Disclosure of Invention

The object of the invention is to provide a suction device of the type mentioned at the outset which can be used in a wide variety of ways with a compact design and which can be operated simply and comfortably.

This object is achieved according to the invention in a suction device of the type mentioned at the outset in that the suction device comprises a suction head, a suction container for receiving suction, a suction fan arrangement, a gripper bow which is mounted on the suction head in a pivotable manner, a holding device which is arranged on the suction head, and a receiving region which is associated with the holding device and is provided on a space for at least partially receiving a cable of the suction device, wherein the receiving region is formed on the outer side of the suction head, wherein the gripping bow can be pivoted from a first position into a second position, in the first position, the grip bow occupies a parking position, and in the second position, the suction device can be held and/or moved by means of the grip bow, and wherein the grip bow defines the boundary of the receiving area in sections when the grip bow is in the first position.

The gripping bow of the suction device can be pivoted by the operator from the first position into the second position. In the first position, the gripper bow assumes a retracted position in which it rests in sections against the suction head and/or is oriented almost horizontally. In the second position, the gripping bow projects almost vertically from the suction head.

In the second position, the suction device and/or the suction head can be held or moved in a simple manner by the operator by means of the gripping bow. The suction device can be rolled or slid over the floor surface, for example by an operator by means of a gripping bow. For example, the operator can remove the suction head from the suction container releasably connected to the suction head by means of the gripping bow and connect it again to this suction container.

The cable of the suction device, for example an electrical connection cable, can be arranged and/or can be held at the holding device and the associated receiving region. The cable can be arranged, for example, in a wound-up state at the holding device and the receiving region.

When the grip bow is in the second position, the operator can access the receiving area from above. The cable can then be arranged, for example, in the receiving region and at the holding device. The operator then moves, for example, the gripper bow into a first position in which it adjoins the receiving region.

When the gripper bow is in the first position, the suction head has a particularly compact shape. This enables a particularly space-saving storage of the suction device with the cable optionally arranged thereon.

By virtue of the fact that the gripper bow delimits the receiving region in sections when the gripper bow is in the first position, the suction head can be designed in a particularly space-saving manner and with a smaller number of components. The gripper bow in the first position serves to block the receiving region upward, so that no additional mechanical parts are required for this purpose.

It may be advantageous for the grip bow to have a pivot angle range of at least 85 ° and/or at most 95 ° between the first position and the second position. The gripper bow can thus be pivoted from a horizontal position into an approximately vertical position, for example.

When the gripper bow is moved from the first position into the second position, the gripping element of the gripper bow is moved away from the receiving area, for example, in order to allow an operator to grip the gripper bow.

When the gripping bow is transferred from the first position into the second position, the gripping elements of the gripping bow are moved at least in sections upwards in relation to the height direction of the suction device, for example, in order for an operator to grip the gripping bow.

It may be advantageous if the gripper bow adjoins the cover element of the suction head and/or surrounds the cover element of the suction head in at least sections in the first position. The suction head can thereby be designed particularly compact.

In particular, it may be provided that, when the gripper bow is in the first position, a spatial gripping region for the gripper bow is associated with the gripper bow, wherein the gripping region is at least partially formed at the receiving region. The gripping bow in the first position can be gripped or held in a simple manner by an operator by means of the gripping area. Furthermore, the receiving region serves in particular both as a storage region for the cable of the suction device and as a gripping region. This enables a particularly compact design of the suction head.

When the gripper bow is in the first position, the gripping area is, for example, at least in sections between the gripper bow and the outer side of the suction head.

When the gripper bow is in the first position, the gripping area is, for example, at least in sections between the gripper bow and the cover element of the suction head.

When the gripper bow is in the first position, the gripping region is formed, for example, between the gripping elements of the gripper bow and the outer side of the suction head, wherein the gripper bow is connected to the suction head by means of at least one leg element.

When the gripper bow is in the first position, for example, between the gripper bow and the suction head, there is an upper opening to the receiving region, which upper opening is arranged above the receiving region with respect to the height direction of the suction device.

When the gripper bow is in the first position, for example, between the gripper bow and the suction head there is a first lateral opening to the receiving region and a second lateral opening to the receiving region, wherein a retaining device is arranged between the first lateral opening and the second lateral opening.

The grip bow can be gripped or held particularly simply in the first position by the hand of the operator by means of the upper opening and/or the first and second lateral openings.

When the gripper bow is in the first position, for example, between the gripper bow and the suction head, there is a first lateral opening to the receiving region and a second lateral opening to the receiving region, wherein the first and second lateral openings extend in the height direction of the suction device between the bottom section bounding the receiving region and the gripper bow, respectively.

When the gripper bow is in the first position, the first leg element and/or the second leg element of the gripper bow is/are oriented, for example, transversely and in particular perpendicularly to the height direction of the suction device, wherein the gripper element of the gripper bow is connected to the suction head by means of the first leg element and/or the second leg element.

When the gripper bow is in the first position, it contacts an abutment region formed on the outer side of the suction head, for example, by at least 50% of the total length of the gripper bow.

When the gripper bow is in the first position, the gripper bow is spaced apart from a central longitudinal axis of the suction device by a greater distance than a wall element of the cover element of the suction head facing the gripper bow, wherein the central longitudinal axis is oriented in the height direction of the suction device. The gripper bow thus forms, for example, in part the outer contour of the suction head, which is thus designed particularly compactly with the gripper bow.

When the gripper bow is in the first position, it does not protrude from the cover element of the suction head, for example, with respect to the height direction of the suction device.

When the gripper bow is in the first position, the gripper bow is retracted relative to the cover element of the suction head, for example with respect to the height direction of the suction device.

When the gripper bow is in the second position, the spatial gripping area associated with the gripper bow is formed, for example, at least in sections, between the gripper bow and the outer side of the suction head.

When the gripper bow is in the second position, the spatial gripping area associated with the gripper bow is formed, for example, at least in sections, between the gripper bow and the cover element of the suction head.

When the gripping bow is in the second position, the gripping elements of the gripping bow for gripping the gripping bow by the operator are arranged, for example, spaced apart from the suction head and/or the cover element of the suction head.

When the gripper bow is in the second position, the first leg element and/or the second leg element of the gripper bow is/are oriented at least approximately parallel to the height direction of the suction head, wherein the gripper element of the gripper bow is connected to the suction head by means of the first leg element and/or the second leg element.

When the gripper bow is in the second position, the suction device and/or the suction head can be carried and/or held and/or moved, for example by an operator, by means of the gripper bow.

It may be advantageous if the gripper bow has a gripping element for gripping the gripper bow by an operator, wherein the gripping element is connected to the suction head by means of the first leg element of the gripper bow and/or by means of the second leg element of the gripper bow. The first leg element and/or the second leg element can be used to connect the gripping bow to the suction head in a mechanically stable and technically simple manner.

It may be advantageous if the pivot axis of the gripper bow is oriented transversely and in particular perpendicularly to the height direction of the suction device. This results in a compact and symmetrical design of the suction head and the gripper bow arranged thereon.

In particular, it can be provided that the gripper bow is arranged in the end region above the suction head with respect to the height direction of the suction device. The gripping bow can thus be accessed by the operator in a simple manner from above at the suction device.

It may be advantageous if an abutment region for the gripper bow is formed on the outer side of the suction head, wherein the gripper bow abuts against the abutment region in the first position. The grip bow can thus rest against the suction head in a defined position.

The contact region is, for example, flat, at least in sections.

The abutment region adjoins the receiving region, for example, at least in sections.

The abutment region is for example tapered into the receiving region.

The abutment region lies, for example, in a plane oriented transversely and in particular perpendicularly to the height direction of the suction device.

The abutment region comprises, for example, a first sub-region for contacting a first leg element of the gripper bow and a second sub-region for contacting a second leg element of the gripper bow, wherein the first leg element is connected to the second leg element by means of the gripper element of the gripper bow.

The abutment region comprises, for example, a first sub-region for contacting a first leg element of the gripper bow and a second sub-region for contacting a second leg element of the gripper bow, wherein a cover element of the suction head is arranged between the first sub-region and the second sub-region. A cover element of the suction head is then arranged, for example, between the first and second sub-regions.

The contact region is arranged, for example, in the outer region and/or in the edge region of the suction head with respect to a transverse direction oriented transversely and in particular perpendicularly to the height direction of the suction device.

In particular, it can be provided that the receiving region is arranged, with respect to the height direction of the suction device, between the gripper bow and a channel arrangement assigned to the extractor arrangement for guiding process air at the suction head when the gripper bow is in the first position.

It may be advantageous if the suction connection end associated with the extractor device and/or the opening device for cooling air associated with the extractor device and/or the operating element device of the suction device are arranged on a first side of the suction device and the holding device and/or the receiving region of the suction device and/or the air outlet associated with the extractor device are arranged on a second side of the suction device facing away from the first side. The components of the suction device can thus be easily accessible to an operator and/or can be arranged at the suction device in a space-saving manner.

It may be advantageous if the holding device is held on the suction head by means of a wall element which is arranged in relation to the height direction of the suction device between the channel device for guiding the process air at the suction head and the receiving region. A mechanically stable support of the holding device and/or the receiving region at the suction head can thereby be achieved.

The receiving region is delimited, for example, by a transverse section formed on the outer side of the suction head, which is oriented transversely to the height direction of the suction device and/or transversely to the contact region for the gripping bow.

The receiving region is delimited, for example, by a base section formed on the outside of the suction head, which is oriented transversely and in particular perpendicularly to the height direction of the suction device.

The transverse section bounding the receiving region is arranged, for example, between the bottom section bounding the receiving region and an abutment region for the gripper bow.

The bottom section which delimits the receiving region forms, for example, a support surface for the cables arranged in the receiving region in relation to the height direction of the suction device.

The smallest angle between the lateral section delimiting the receiving region and the bottom section delimiting the receiving region is, for example, at least 60 ° and/or at most 70 °.

The receiving region is arranged, for example, in relation to the height direction of the suction device, above the channel arrangement for guiding the process air at the suction head and/or above the air outlet for guiding the process air at the suction head.

The receiving region extends, for example, at least in sections between the holding device and the outside of the suction head.

The receiving region extends, for example, at least in sections between the holding device and a transverse section arranged on the outer side of the suction head, which transverse section delimits the receiving region.

The receiving region is arranged, for example, in a region on a space bounded by a stable outer contour of the suction head, wherein the outer contour extends through an outer side of the suction head, which outer side adjoins the receiving region in the circumferential direction of the suction head, and wherein the circumferential direction is oriented transversely and in particular perpendicularly to the height direction of the suction device.

The outer contour has, for example, at least approximately a constant curvature and/or a constant radius of curvature.

The outer side of the holding device is located, for example, in the outer contour.

The receiving region is configured, for example, as a cutout and/or a recess and/or a depression at the suction head.

In particular, it can be provided that the holding device and/or the receiving region are at least approximately symmetrically configured with respect to a center plane extending parallel to the height direction of the suction device. This allows a symmetrical design of the holding device and/or the receiving region at the suction head, wherein the suction head is designed, in particular, at least in sections, as a mirror image with respect to the center plane.

The holding device is arranged, for example, in the outer region and/or in the edge region of the suction head with respect to a transverse direction oriented transversely and in particular perpendicularly to the height direction of the suction device. The receiving region and/or the holding device can thus be accessed by an operator in a simple manner. In this way, for example, the cable can be arranged in the receiving region and/or on the holding device, wherein the cable projects partially beyond the outer region and/or the edge region of the suction head.

The holding device extends, for example, from a lower end of the receiving region to an upper end, wherein the upper end is arranged at a distance from the lower end in the height direction of the suction device.

The holding device comprises, for example, a hook element for holding and in particular suspending the cable and/or a hook element configured for holding and in particular suspending the cable.

It may be advantageous for the holding device to have a first region connected to the suction head and a second region connected to the first region, wherein the second region is arranged above the first region with respect to the height direction of the suction device. The holding device can thus be manufactured and/or constructed in a technically simple manner.

The second region is arranged, for example, in the upper end region of the holding device.

The second region for example rests on the gripper bow when the gripper bow is in the first position.

The second region projects, for example, from the first region in the direction of the cover element of the suction head and/or in the direction of a transverse section of the suction head which delimits the receiving region.

The holding device narrows, for example, with respect to the width of the holding device from the end of the holding device facing away from the gripper bow to the end of the holding device facing toward the gripper bow, wherein the width direction lies in a plane oriented transversely and in particular perpendicularly to the height direction of the suction device. This enables a simple grip of the gripping bow by the operator in the first position, wherein the holding device is then arranged, for example, between different fingers of the operator.

The holding device has, for example, an upper end face which is at least approximately parallel to an abutment region for the gripping bow arranged at the suction head. An abutment region for the gripping bow can thereby be formed at least partially at the holding device.

The holding device has, for example, an upper end face which is aligned flush with the contact region for the gripper bow.

When the gripper bow is in the first position, it rests, for example, on the upper end face of the holding device.

The retaining device blocks the cable arranged in the receiving region, for example in an upward direction oriented with respect to the height direction of the suction device and/or in a direction pointing towards the cover element of the suction head.

The holding device blocks the cable arranged in the receiving section, for example in an outward direction, wherein the outward direction is oriented transversely and in particular perpendicularly to the height direction of the suction device and/or wherein the outward direction is directed away from the suction head.

When the gripper bow is in the first position, the holding device extends, for example, at least in sections in a direction oriented transversely and in particular perpendicularly to the gripper bow.

In one embodiment, the suction device comprises a holding element for a tube element of the suction device which performs a suction process and/or a blowing process, wherein the holding element is arranged on the outside of the suction head. The tube element can thus be fixed and/or stored at the suction device.

The pipe elements are constructed, for example, to be rigid and/or flexible. The tube element is or comprises, for example, a flexible hose element, such as a suction hose of a suction device.

The holding element is arranged, for example, in relation to the circumferential direction of the suction head, which is oriented perpendicularly to the height direction of the suction device, between the gripper bow and the operating element arrangement of the suction device. The tube element can thereby be arranged at the suction device at a distance from the holding device and/or the receiving region.

The holding element is arranged, for example, with respect to the circumferential direction of the suction head, which is oriented perpendicularly to the height direction of the suction device, between a pivot joint, by means of which the gripper bow is connected to the suction head, and an operating element arrangement of the suction device.

The holding element is arranged at least approximately at the level of the contact region for the gripping bow, for example with respect to the height direction of the suction device.

The holding element is arranged, for example, in the outer region and/or in the edge region of the suction head with respect to a transverse direction oriented transversely and in particular perpendicularly to the height direction of the suction device. This allows the holding element to be accessible to the operator in a simple manner at the suction device.

It may be advantageous for the cable of the suction device to be arranged as a winding wire, and in particular suspended as a winding wire, at the receiving region. The cable can thus be stored in a simple and space-saving manner at the holding device and the receiving region.

In particular, it can be provided that the movement of the cable arranged in the receiving region is blocked upward by the gripper bow with respect to the height direction of the suction device when the gripper bow is in the first position.

In particular, it can be provided that the receiving region is accessible to an operator from the outside and/or that the receiving region is an outwardly open region when the grip bow is in the second position. The cable can then be arranged, for example, in the receiving region and, for example, as a coiled wire.

In one embodiment, the suction device comprises at least one accessory holding element for accommodating and/or storing accessories for the suction device, wherein the at least one accessory holding element is arranged at the cover element of the suction head. This makes it possible to easily and safely hold and/or store the accessory at the suction device.

In particular, it can be provided that the cover element of the suction head has an upper side on which a bearing surface for arranging and/or storing accessories for the suction device is formed, and that, in particular, when the gripper bow is in the second position, accessories for the suction device can be arranged and/or stored on the upper side. This makes it possible, for example, to place or temporarily store the attachment on the upper side using the suction device means.

In particular, it can be provided that the suction fan device is arranged at the suction head.

In one embodiment, the suction device comprises a locking device for fixing and/or locking the gripper bow in the first position. The grip bow can be fixed and/or locked on the holding device by means of a locking device.

In one embodiment, the suction device comprises a spring device associated with the gripper bow, wherein the gripper bow can be moved from the first position into the second position in the direction of the spring force exerted by the spring device or in the opposite direction.

In particular, it can be provided that the gripper bow is pivotably supported by means of at least one pivot joint on the cover element of the suction head.

The at least one pivot joint comprises, for example, a sleeve element arranged on the cover element for receiving a journal element of the at least one pivot joint, wherein the journal element is arranged on the grip bow and in particular on the leg elements of the grip bow.

The sleeve element of the at least one pivot joint for receiving the journal element of the at least one pivot joint is arranged, for example, on a wall element of the cover element facing the gripper bow, wherein the wall element is oriented transversely and in particular perpendicularly to an abutment region for the gripper bow, against which the gripper bow rests in the first position.

The journal element of the at least one pivot joint, which journal element is arranged on the gripper bow, for example, protrudes in the direction of the cover element of the suction head.

The journal element of the at least one pivot joint, which journal element is arranged at the gripper bow, extends, for example, at least approximately parallel to the pivot axis of the gripper bow.

The journal element of the at least one pivot joint is arranged, for example, at an end and/or a tip region of the gripper bow.

When the grip bow is in the first position, the journal element of the at least one pivot joint can be moved out of and/or removed from the sleeve element of the at least one pivot joint, for example by exerting a force on the leg element of the grip bow, wherein the journal element is arranged at the leg element. In this way, the gripper bow can be mounted and/or dismounted on the suction head in the first position without tools.

When the grip bow is in the second position, the journal element of the at least one pivot hinge, for example, cannot be moved out of and/or removed from the sleeve element of the at least one pivot hinge. This prevents the gripper bow from being unintentionally released from the suction head in the second position.

When the gripper bow is in the second position, for example, a limiting element arranged on the suction head and a stop element arranged on the gripper bow are associated with the at least one pivot joint, wherein the movement and/or removal of the journal element of the at least one pivot joint out of the sleeve element of the at least one pivot joint is prevented by the interaction of the limiting element and the stop element, and/or the movement and/or removal of the journal element out of the sleeve element is enabled when the gripper bow is in the first position.

The limiting element associated with the at least one pivot joint is arranged, for example, in an abutment region for the gripper bow, against which the gripper bow abuts in the first position.

For example, a groove is formed at the gripper segment, wherein the limiting element associated with the at least one pivot joint can be passed through or through the groove when the gripper segment is moved from the first position into the second position.

In particular, it can be provided that the gripper bow can be mounted on the suction head in a tool-free manner and/or can be detached from the suction head in a tool-free manner. In particular, a tool-free mounting and/or dismounting of the gripper bow in the first position at the suction head can be achieved. In particular, tool-free mounting and/or dismounting of the gripper bow in the second position is not possible.

The (tool-free) mounting and/or demounting is understood to mean, in particular, a mounting and/or demounting that is damage-free.

It may be advantageous if the aspirate container is releasably connected to the suction head. The suction head can thus be separated from the aspirate container, for example by an operator, in order to empty the aspirate container. The aspirate container can then be connected to the suction head.

It may be advantageous if the suction connection associated with the extractor device is arranged and/or formed at the suction container. The suction air flow can thereby be directly coupled (einkoppeln) into the aspirate container by means of the suction fan device, wherein the dirt fraction of the suction air flow is discharged into the aspirate container and/or out of the filter unit. The clean air is then coupled into the suction head by means of the ventilator device and is coupled out from this suction head via an air outlet (auskoppeln).

In one embodiment, the suction head comprises a suction head housing at which the receiving region and/or the holding device are arranged and/or constructed.

It may be advantageous if the cable of the suction device is guided outwards from the suction head by means of a cable outlet, wherein the cable outlet is arranged spaced apart from the receiving region with respect to the circumference of the suction head, wherein the circumference is oriented perpendicular to the height direction of the suction device. The cable can thus be accessed in a simple manner by an operator of the suction device and can be arranged and/or wound at the holding device and/or in the receiving region in a simple manner.

The cable outlet is arranged below the receiving region, for example, with respect to the height direction of the suction device.

The cable outlet is arranged, for example, in the circumferential direction between the receiving region and a pivot joint of the gripper bow, by means of which the gripper bow is connected to the suction head.

The suction head and/or the suction head housing can thus be constructed in a technically simple manner.

In particular, it can be provided that the suction device is provided and designed as a wet/dry suction unit and/or as a mobile suction unit and/or as a separate suction unit.

Process air refers to air which is drawn by means of the extractor device via the suction connection of the suction device and subsequently coupled out through the air outlet. Process air is not to be understood in particular as air for cooling the extractor device or air which is associated with the cooling air guide of the extractor device.

The longitudinal center axis of the suction device is the longitudinal axis of the suction device oriented in the height direction of the suction device. The suction device is, for example, configured to be at least rotationally symmetrical in sections about a longitudinal center axis.

When the suction device is positioned in the operating state in a defined manner, the longitudinal center axis and/or the height direction are oriented at least approximately parallel to the direction of gravity.

The term "upper" or "lower" and/or the "upper" or "lower" elements of the suction device are always used to refer to the height direction relative to the suction device, wherein this can be based on a defined positioning of the suction device in the operating state (for example, a roller arrangement on the ground).

Unless otherwise stated, the description "about" and "at least approximately" means that the geometry deviates on average by at most 10% from the stated ideal geometry or that the values and/or spacings and/or angles deviate at most 10% from the stated values and/or spacings and/or angles. A deviation of a geometric shape from an ideal geometric shape by a percentage, for example, a deviation of a width and/or length and/or height of the corresponding geometric shape from an average of a width and/or length and/or height of the ideal geometric shape.

One exemplary embodiment of a suction device, which is illustrated in fig. 1 to 17 and is designated therein by reference numeral 10, is a mobile suction device and is designed as a self-contained unit. The suction device 10 is configured, for example, as a wet/dry suction.

The suction device 10 comprises a suction container 12 with a receiving space 14 for suction. The aspirate container 12 is barrel-shaped and has, for example, a cylindrical shape.

The aspirate container 12 comprises a bottom element 16 and a wall element 18 arranged at the bottom element 16, which wall element delimits the receiving space 14. The wall element 18 has for example a cylindrical shape.

A suction head 20 is arranged at the suction container 12 in a releasable and in particular removable manner. A suction fan device 22 is arranged at the suction head 20, which generates a suction flow in the operating state of the suction device 10. The blower device 22 comprises a motor 24, in particular an electric motor, and a blower unit 26 (blower) which is driven by the motor 24.

The suction device 10 has a central longitudinal axis 28, wherein the suction device 10 is configured to be rotationally symmetrical, in particular at least in sections, about the central longitudinal axis 28. The aspirate container 12 and/or the suction head 20 are, for example, at least in sections rotationally symmetrical about a central longitudinal axis 28.

When the suction device 10 is positioned in the operating state as intended, the longitudinal center axis 28 is oriented at least approximately parallel to the direction of gravity 30.

The longitudinal center axis 28 of the suction device 10 is in particular an axis which is oriented parallel to a height direction 32 of the suction device 10, wherein the base element 16 is arranged, for example, at a lower height (that is to say at a much lower or lower gravitational potential energy) than the suction head 20 with respect to this height direction 32 when the suction device 10 is positioned as intended in the operating state.

The following references to "upper" or "lower" and/or "upper" or "lower" elements of the suction device 10 always refer to the height direction relative to the suction device 10, wherein this can be based on the fact that the suction device 10 is positioned as intended in the operating state.

On the suction container 12, a suction connection 34 is arranged spaced apart from the base 16 and/or above the base 16, via which suction connection a suction air flow can be coupled by means of a suction fan device 22 through the suction container 12 into the suction fan device 22 arranged at the suction head 20. A connecting device 36 for a pipe element of the suction device 10 is associated with this suction connection end 34, wherein the connecting device 36 is arranged and/or formed, for example, at least in part at the suction connection end 34.

The pipe elements are constructed, for example, to be rigid and/or flexible. The tube element is, for example, a flexible hose element, such as a suction hose of the suction device 10. The suction process may be performed by an operator of the suction device 10, for example, by means of a tube element.

A fluid-effective, releasable connection can be established between the suction coupling end 34 and the pipe element by means of the connecting device 36. In order to establish a releasable connection of the pipe element to the connecting device 36, the pipe element comprises adapter means.

The suction connection end 34 comprises, for example, an opening 38, which is, for example, circular in shape and is arranged at the aspirate container 12 at a distance from the base 16 and/or above the base 16. The opening 38 is arranged or formed, for example, at the wall element 18 of the suction container.

By means of the suction coupling end 34 and the connecting device 36, a releasable, fluid-effective connection can be established between the pipe element and the suction coupling end 34. A fluid-effective connection can thus be established between the tube element and the receiving space 14 of the aspirate container 12 by means of the suction connection end 34, for example via the opening 38.

In one embodiment, a stand 40 is associated with the aspirate container 12. This stand 40 is, for example, annular in shape and has a receiving region 42 for the aspirate container 12.

The receiving region 42 is delimited, for example, by a projection 43 of the stand 40.

The stand 40 comprises rollers 44 by which the stand 40 and thus the suction device 10 can be moved. It can also be provided that "removable" rollers are arranged on the stand 40 and that the suction device 10 can be slid on the ground by means of the stand 40 when the "rollers are retracted" or can be moved on the ground by means of the rollers when the "rollers are removed", depending on the application.

The aspirate container 12 is closed off towards an upper side 46 of the aspirate container (in the direction away from the base element 16) by a lower side 48 of the suction head 20 arranged at the aspirate container 12.

Alternatively or additionally, it is also possible for the aspirate container 12 to be closed by a separate aspirate container lid (not shown).

When the adapter device 186 is connected to the connecting device 184 as intended, the adapter device 186 is arranged in particular at least partially in the interior 70 of the suction head housing 68.

The adapter device 186 comprises, for example, a mechanical connecting element 188, for example a latching element, wherein a releasable connection can be established between the adapter device 186 and the connecting device 184 by means of the connecting element 188.

The channel unit 96 and/or the closure device 185 are arranged and designed in such a way that the second channel 108 is closed in the suction head housing 68 in a fluid-tight manner relative to the connecting channel 166 when the adapter device 186 is connected to the connecting device 184 as intended. In this case, the process air to be coupled out is coupled out only via the first channel 106 and the first air outlet 102 by means of the channel arrangement 96.

When the adapter device 186 is decoupled from the connecting device 184, in the interior 70 both the first channel 106 and the second channel 108 are fluidically connected effectively to the connecting channel 166, so that a coupling-out of process air via both the first channel 106 and the first air outlet 102 and the second channel 108 and the second air outlet 104 is possible.

A wall element is assigned to the closing device 185, which wall element can assume a first position in which the air inlet openings 160 of the second channels 107 are released, and a second position in which the air inlet openings 160 are blocked by means of the wall element 189.

In the exemplary embodiment shown, the wall element assigned to the closure element 185 is formed at the adapter device 186. When the adapter device 186 is properly connected to the connecting device 184, the air inlet opening 160 of the second channel 108 is blocked and/or closed by means of the wall element 189 of the adapter device 186. The wall element 189 is then, for example, arranged in the interior 70 of the suction head housing 68 and/or covers the air inlet opening 160 (second positioning of the wall element 189).

When the adapter device 186 is disconnected from the connection device 184, air is released into the opening 160 (first positioning of the wall element 189).

The wall element 189 has for example a cylindrical shape and/or defines a flow space 187 for air formed in the adapter device 186.

The connection 184 for the first air outlet 102 is in particular configured in the same way as the connection 36 for the suction connection end 34, so that, for example, a tube element 186a can be connected in a fluid-effective manner releasably by means of the adapter device 186 also with the connection 36 for the suction connection end 34.

The center point 190 and/or the center of gravity of the suction fan device 22 is arranged on a first side 194 with respect to a central plane 192 of the suction device 10, which extends through the longitudinal center axis 28. The connecting channel 166 is arranged substantially on a second side 196, wherein the second side 196 is opposite the first side 194 with respect to the central plane 192.

The first air outlet 102 is arranged on the second side 196 with respect to the central plane 192 and the second air outlet 104 is arranged on the first side 194 with respect to the central plane 192.

The suction device 10 has a gripper bow 202, which is pivotably supported at the suction head 20 and is arranged in a tip region 204 of the suction device 10 and/or of the suction head 20 with respect to the height direction 32. The grip bow 202 is configured, for example, in a U-shape.

The grip bow 202 is pivotable from a first position 203a (see fig. 2) into a second position 203b (see fig. 1). In the first position 203a, the gripper bow 202 is oriented approximately horizontally in the operating state when the suction device 10 is positioned as intended. In the second position 203b, the gripper bow 202 is oriented approximately vertically.

The gripper bow 202 forms, in particular, at least in sections, the outer contour of the suction head housing 68 when the gripper bow is in the first position 203 a.

In the illustrated embodiment, the gripper bow 202 is oriented at least approximately parallel to the upper side 78 of the cover element 76 in the first position 203 a.

In the second position 203b, the gripper bow 202 is located, for example, at least approximately in a central plane (not shown) extending through the longitudinal center axis 28 of the suction device 10.

When the gripper bow 202 is in the first position 203a, the region 205 above the gripper bow 202 is located at least approximately at the level of the upper side 78 with respect to the height direction 32.

The grip bow 202 has a first leg element 206 and a second leg element 208, wherein the first leg element 206 and the second leg element 208 are connected to each other by means of a grip element 210.

The first leg member 206 and the second leg member 208 are each connected to the suction head housing 68 by a pivot hinge 212. The pivot hinge 212 is arranged in the end region 204 above the suction head 20.

The first leg element 206 is pivotably connected to the suction head 20, for example by means of a first pivot hinge 212a and the second leg element 208 by means of a second pivot hinge 212 b.

The pivot joint 212 is arranged in the outer region 214 and/or in the edge region of the suction head housing 68 with respect to the transverse direction 174 lying in a plane oriented transversely and in particular perpendicularly to the longitudinal center axis 28. The pivot joint 212 is located at least approximately in a central plane (not shown) extending through the longitudinal mid-axis 28.

The outer region 214 and/or the edge region refers to the region lying outside the region at the suction-head housing 68 with reference to a direction oriented transversely and in particular perpendicularly to the longitudinal center axis 28.

A spatial receiving region 216 is associated with the holding device 92, which is formed on the outside 218 of the suction head housing 68. When the grip bow 202 is in the first position 203a, the grip bow 202 abuts the accommodation region 216 and/or defines a boundary of the accommodation region 216.

The outer side 218 refers to the side of the suction head housing 68 and/or the suction head 20 facing away from the inner chamber 70. The outer side 218 is in particular the side facing the operator of the suction device 10.

The retaining device 92 and the receiving region 216 are arranged between the channel device 96 and the cover element 76 with respect to the height direction 32.

The holding device 92 and the receiving region 216 are provided and designed in particular for holding the cable 94 and/or for partially receiving the cable 94, for example in the wound-up state.

The grip bow 202 surrounds the cover element 76 in the first position 203a in a U-shaped and/or semicircular manner. The cover element 76 is further inward with respect to the transverse direction 174 than the gripper bow 202.

The grip bow 202 abuts, for example, the cover element 76 in the first position 203 a. The gripping element 210 is arranged in the first position 203a, for example, on the second side 90 of the suction device 10.

The gripper bow 202 can be pivoted by the operator from the first position 203a into the second position 203b (or vice versa) by means of the gripper element 210. In the second position 203b, the gripping element 210 is arranged spaced apart from the upper side 78 of the suction head housing 68.

The handle element 210 can be grasped and/or held by an operator. The suction device 10 can be held and/or moved, for example, by gripping the grip element 210.

When the gripper bow 202 is in the first position 203a, a spatial gripping region 220 is associated with the gripping elements 210 of the gripper bow 202. The gripping element 210 may thus be gripped and/or held by an operator in the first position 203 a. The gripping area 220 serves in particular to accommodate the hands and/or fingers of the operator when the operator grips the gripping element 210 in the first position 203 a.

The grip region 220 is at least partially formed in the receiving region 216.

Furthermore, the grip region 220 extends at least partially between the grip element 210 and the outer side 218 of the suction head housing 68. A section of gripping area 220 extends, for example, between gripping element 210 and a wall element 221 of cover element 76 facing toward gripping element 210. This wall element 221 is oriented, for example, at least approximately parallel or transverse to the longitudinal center axis 28 of the suction device 10.

When the gripper bow 202 is in the first position 203a, an upper opening 222 is formed between the gripping element 210 of the gripper bow 202 and the outer side 218 of the suction head housing 68. The upper opening 222 is accessible from above with respect to the height direction 32 and/or is arranged at least approximately at the height of the upper side 78 of the cover element 76 with respect to the height direction 32.

Furthermore, when the grip bow 202 is in the first position 203a, a first lateral opening 224 and a second lateral opening 226 spaced apart from the first lateral opening 224 in the circumferential direction 100 are formed between the grip element 210 and the outer side 218. The first and second lateral openings 224, 226 are disposed on the second side 90 of the suction apparatus 10 and/or are accessible from the second side 90 of the suction apparatus 10. A retaining device 92 is arranged between the first lateral opening 224 and the second lateral opening 226.

The first lateral opening 224 and the second lateral opening 226 each extend in particular in a plane which is transverse and in particular perpendicular to the plane in which the upper opening 222 extends.

The first lateral opening 224 and the second lateral opening 226 extend between a bottom section 228 formed at the outer side 218 of the suction head housing 68, which bottom section delimits the receiving region 216, and the gripping element 210 of the gripping bow 202.

The upper opening 222 extends, for example, between the grip element 210 and the wall element 221 of the cover element 76.

The bottom section 228 is formed on a wall element 229 of the suction head housing 68, which is arranged in the height direction 32 between the channel arrangement 96 and the receiving region 216. The holding means 92 is arranged at the wall element 229.

When the grip bow 202 is in the first position 203a, the receiving region 216 is accessible through the upper opening 222, the first lateral opening 224 and the second lateral opening 226, for example, for an operator's hand to grip the grip element 210.

A particularly flat contact region 230 is formed on the outer side 218 of the suction head housing 68, which at least sectionally adjoins the receiving region 216 and/or tapers into the receiving region 216. In the first position 203a, the gripper bow 202 rests at least in sections against the abutment region 230.

The abutment region 230 is not necessarily configured to be spatially coherent. In the example shown, the abutment region 230 comprises a first sub-region 230a for contacting the first leg element 206 of the grip bow 202 and a second sub-region 230b for contacting the second leg element 208. The first and second subregions 230a, 230b are arranged, for example, opposite one another on the suction head housing. The first and second partial regions 230a, 230b are arranged on different sides and/or on opposite sides of the cover element 76 of the suction head housing 68.

The abutment region 230 lies, for example, in a plane oriented transversely and in particular perpendicularly to the longitudinal mid-axis 28. The abutment region 230 extends between the pivot joint 212 and the receiving region 216 in the outer region 214 and/or in the edge region of the suction head housing 68.

The abutment region 230 and/or the first sub-region 230a and/or the second sub-region 230b taper, for example, into a transverse section 232 formed at the outer side 218 that defines a boundary of the accommodation region 216. This transverse section 232 is oriented transversely to the abutment region 230 and/or the bottom section 228. The transverse section 232 is arranged between the bottom section 228 and the abutment region 230.

The smallest angle between the transverse section 232 and the bottom section 228 is, for example, about 65 °.

The holding device 92 and the associated receiving region 216 are configured at least approximately mirror-symmetrically with respect to a plane, for example with respect to a central plane 192 extending through the longitudinal center axis 228.

The holding device 92 and the associated receiving region 216 are arranged in relation to the transverse direction 174 in an outer region 214 and/or in an edge region of the suction head housing 68, wherein the holding device 92 is arranged at an outer contour 234 of the suction head housing 68.

The outer contour 234 is a limiting line and/or limiting surface which is external to the suction head housing 68 with respect to the transverse direction 174 and which is oriented, for example, in the circumferential direction 100. Outer contour 234, for example, has at least approximately a constant curvature and/or a constant radius of curvature.

The outer contour 234 extends, for example, over an outer side 235 of the suction head housing 68 in the outer region 214 and/or in the edge region, which outer side adjoins the receiving region 216 in the circumferential direction 100.

The receiving region 216 is configured as a recess with respect to the outer contour 234.

The receiving region 216 extends from the outer contour 234 and/or from the holding device 92 inward (toward the cover element 76 and/or the longitudinal center axis 28).

The retaining device 92 extends in the height direction 32 from a lower end 236 to an upper end 238 of the receiving region 216. The bottom section 228 is, for example, arranged at the level of the lower end 236 and the transverse section 232 extends between the lower end 236 and the upper end 238.

The holding device 92 is configured, for example, as a hook element 239 or comprises a hook element 239.

The holding device 92 comprises a second region 240 which is arranged in an end region 242 above the holding device 92. The second region 240 is connected to a first region 244 of the holding device 92, wherein the first region 244 is connected to the suction head housing 68.

The second region 240 is connected to the first region 244, for example by means of a screw connection. The first region 244 is connected integrally to the suction head housing 68, for example.

The second region 240 protrudes beyond the first region in the transverse direction 174. The second region 240 projects beyond the first region 244, for example in the transverse direction 174, toward the cover element 76 and/or the longitudinal center axis 28.

The retaining device 92 has a width B1, wherein the width direction is oriented in the circumferential direction 100 of the suction head housing 68. The width B1 is greatest at the lower end 246 of the retainer 92 and smallest at the upper end 248 of the retainer 92.

The lower end 246 is located at the level of the lower end 236 of the receiving region 216 and the upper end 248 is located at the level of the upper end 238 of the receiving region 216.

The holding device 92 has an upper end face 250 which is oriented at least approximately parallel to the contact region 230. The upper end face is located at least approximately at the height of the contact region 230, for example with respect to the height direction 32. The abutment region 230 and the upper end face 250 lie, for example, at least approximately in one plane.

When the gripper bow 202 is in the first position 203a, the gripping elements 210 of the gripper bow 202 rest, for example, on the upper end face 250. The upper end face 250 forms, for example, an abutment region for the gripper bow 202 and/or the gripper element 210.

The retaining device 92 has an outer side 252 which faces away from the receiving region 216 and/or the longitudinal center axis 28. This outer side 252 is located, for example, in outer contour 234.

It can be provided that a locking device 254 is associated with the gripper segment 202, by means of which the gripper segment 202 can be fixed and/or snapped into and/or locked in the first position 203 a. The grip bow 202 can be fixed and/or snapped and/or locked in the first position 203a at the holding device 92, for example, by means of a locking device 254.

In one embodiment, a spring device 256 is associated with the gripper bracket 202, by means of which spring device the gripper bracket 202 can be moved from the first position 203a into the second position 203b in or against the direction of the spring force exerted by the spring device 256. The spring device 256 is arranged or constructed, for example, at least one of the pivot joints 212.

The first pivot hinge 212a includes a journal element 258, the journal element 258 being disposed and/or configured at the first leg element 206. This journal element 258 extends from the first leg element 206 in the direction of the cover element 76 of the suction head 20 when the gripper bow 202 is positioned as intended at the suction device 10. The journal element 258 projects, for example, from the first leg element 206 in the direction of the cover element 76.

The first pivot joint 212a and/or the journal element 258 are arranged, for example, at the end 259 at the cover element 76 and/or at the end region of the gripper bow 202.

Furthermore, the first pivot hinge 212a comprises a sleeve element 260 for rotatably supporting the journal element 258. The journal element 258 can be received by a sleeve element 260 and/or the journal element 258 can be retracted into the sleeve element 260, for example.

The journal element 258 can be arranged, for example, on the sleeve element 260 and/or can be introduced into the sleeve element 260 toward the cover element 76.

The sleeve element 260 is arranged and/or constructed at the cover element 76. The sleeve element 260 is configured, for example, as a recess at a wall element 262 of the cover element 76 facing the first leg element 206 and/or the journal element 258.

When the grip bow 202 is in the first position 203a, the wall element 221 of the cover element 76 facing the grip element 220 is coupled to the wall element 262, for example in the circumferential direction 100.

The first pivot hinge 212a is constructed in the illustrated embodiment identically to the second pivot hinge 212 b.

By means of the first pivot joint 212a and/or the second pivot joint 212b, the gripper bow 202 can be pivoted about a pivot axis 264 and/or a rotation axis, which is oriented, for example, transversely or, in particular, perpendicularly to the longitudinal center axis 28 and/or the height direction 32.

In one embodiment, a limiting element 266 associated with the first pivot joint 212a is provided, by means of which the movement of the first leg element 206 in the direction away from the cover element 76 is blocked when the gripper bow 202 is in the second position 203 b. Accordingly, it can be provided that a limiting element 266 is associated with the second pivot joint 212 b.

The limiting element 266 is arranged at the suction head 20 spaced apart from the cover element 76 and/or spaced apart from the sleeve element 260 in the example shown. The delimiting element 266 is arranged in a region 268 at the pivot hinge 212 a.

The delimiting element 266 is arranged, for example, at the first subregion 230a of the abutment region 230. The limiting element 266 is configured, for example, as a projection.

The grip bow 202 includes a wall element 268 facing toward the inside of the cover element 76 and a wall element 270 facing away from the outside of the cover element 76. The journal element 258 is arranged in particular at the inner wall element 268.

In particular, a gap 272 is formed between the inner wall element 268 and the outer wall element 270, which gap is open in particular toward an underside 274 of the gripper bow 202, wherein the underside 274 faces the abutment region 230 when the gripper bow 202 is in the first position 203 a.

In the gap 272, for example, one or more rib elements 276 are arranged, which are arranged between the inner wall element 268 and the outer wall element 270. The rib element 276 is oriented, for example, transversely and in particular perpendicularly, to the inner wall element 268 and/or the outer wall element 270.

The limiting element 266 is arranged at least in sections in the gap 272 and/or at least in sections between the inner wall element 268 and the outer wall element 270.

When the gripper bow 202 is in the second position 203b, the limiting element 266 is arranged between the outer wall element 270 and the stop element 278. When the gripper bow 202 is in the second position, this stop element 278 can bear against the limiting element 266 and thus prevent a movement of the first leg element 206 in one direction away from the cover element 76.

When the grip bow 202 is in the second position, the first leg element 206 is prevented from moving in a direction away from the cover element 76 by the cooperation of the limiting element 266 and the stop element 278. Thereby preventing the journal element 258 from moving out of the sleeve element 260 in the second position 203 b.

The stop element 278 can be pivoted and/or rotated relative to the limiting element about the pivot axis 267, so that the gripper bow 202 can be moved from the second position 203b into the first position 203 a.

The stop element 278 is arranged, for example, in the gap 272 between the outer wall element 270 and the inner wall element 268. The stop element 278 is arranged, for example, on a rib element 276a, which is oriented transversely and in particular perpendicularly to the inner wall element 268 and/or the outer wall element 270. The stop element 278 is oriented, for example, transversely and in particular perpendicularly to the rib element 276 a.

Provision can be made for a groove 280 to be formed at the rib element 276a, wherein the limiting element 266 can be guided or guided at least in sections through the groove 280 when the grip bow 202 is moved from the second position 203b into the first position 203 a.

In the first position 203a, the limiting element 266 is arranged spaced apart from the stop element 278. The stop element 278 can then be moved relative to the delimiting element 266, in particular without being obstructed by the delimiting element 266. The gripper bow 202 is movable in the first position 203a, for example, between a first position in which the limiting element 266 rests against the outer wall element 270 and a second position in which the limiting element 266 rests against the inner wall element 268 (see fig. 14 and 15).

In the first orientation, the journal element 268 is disposed in the sleeve element 260. In the second orientation, the journal element 258 is disposed outside of the sleeve element 260. In this way, the gripper bow 202 can be mounted and/or dismounted without tools at the suction head 20 in the first position 203 a.

The suction device according to the invention works as follows:

to perform a suction process with the suction apparatus 10, the operator connects, for example, a suction hose of the suction apparatus 10 with the suction coupling end 34. The operator then switches on the suction device 10, for example by means of the operating element arrangement 82. The respective parameters of the suction process can be controlled, for example, by an operator by means of the operating element arrangement 82.

The (dirty) process air is coupled into the receiving space 14 of the aspirate container 12 by means of the suction fan device 22 via the suction connection 34.

The dirty part of the process air supplied in is discharged into the receiving space 14 of the aspirate container 12 and/or to the dirty side 64 of the filter unit 56.

The (clean) process air is coupled into the suction fan device 22 via the clean side 60 of the filter unit 56. This process air is then coupled out of the suction head 20 via the channel arrangement 96 via the first air outlet 102 and the second air outlet 104.

To empty the aspirate container 12, the fastening device 52 is opened and the suction head 20 is subsequently lifted upwards from the aspirate container 12 by means of the gripper bow 202. For this purpose, the gripper bow 202 is moved into the second position 203b by the operator. After emptying the aspirate container 12, the suction head 20 is again placed onto the aspirate container 12 by means of the gripper bracket 202 and is fixed to this aspirate container by the fixing device 52.

In order to carry out the blowing process by means of the suction device 10, the suction hose is connected by means of an adapter unit 186 to the connection 184 of the first air outlet 102.

The closing device 185 is thus switched from the first state into the second state, so that no process air is coupled out of the suction head 20 via the second air outlet 104. The coupling-out of the process air is then effected via the first air outlet 102 and in particular via the first air outlet 102 only.

The process air is thus coupled into the suction hose and is coupled out again at one end of the suction hose, so that the blowing function can be used by the operator with the aid of the suction hose.

To store the suction device 10, the suction hose is, for example, released from the suction coupling end 34 and/or the connection 184. The suction hose can be fastened and/or stored at the suction head 20, for example, by means of the holding element 79.

The cable 94 of the suction device 10 can be held and/or stored at the suction head 20 by means of the holding device 92 and the receiving region 216 associated with the holding device 92.

In order to arrange the cable 94 in the receiving region 216, the operator switches the grip bow 202 into the second position 203b, so that the receiving region 216 is accessible from above at the suction head 20 (see, for example, fig. 1). In this state, the cable 94 is arranged in the receiving region 216 and is arranged there, for example, wound up and/or as a coiled wire.

The operator then switches the gripper bow 202, for example, into the first position 203a, so that the gripper bow 202 adjoins the receiving region 216. In this position of the grip bow 202, the cable 94 arranged in the receiving region 214 is blocked against movement in an upward direction and outward in the transverse direction 174 (see, for example, fig. 2).

To remove the cable 94 from the receiving region 216, the operator switches the grip bow from the first position 203a into the second position 203b, so that the cable 94 can be removed upward from the receiving region 216 (see, for example, fig. 1).

In order to remove the gripper bow 202 without a tool, this gripper bow is transferred into the first position 203 a. The first leg element 206 is pressed by the operator outwardly away from the cover element 76 until the limiting element 266 bears against the inner wall element 268 and/or until the journal element 258 is removed from the sleeve element 260 (see fig. 15). The first leg element 206 can then be moved upward away from the suction head when the journal element 258 is disengaged. When the first leg element 206 is hung off, this operation is repeated with the second leg element 208 accordingly, so that the gripper bow 202 is released from the suction head 20. For tool-less mounting, the steps are carried out correspondingly in the reverse order.
