Background

The present invention relates to a furniture element, in particular a shelf or a shelf unit according to the preamble of claim 1.

Furniture elements such as shelves or shelf units are known, for example, from JP 10318669 or DE 102017106170 a1, in which a support plate and a shelf guided thereon and simultaneously rotatable and translatable are arranged.

In particular, the supporting plate described in the latter publication has been proven in practice.

In the case of such shelves or shelving units, there is often the problem that: on the one hand, to protect the items stored thereon from dust contamination and, on the other hand, to allow good access to the items. Furthermore, these shelves or shelf units must always be placed at a distance from the side walls to allow them to rotate without hitting the side walls.

Disclosure of Invention

It is an object of the invention to provide a furniture element comprising at least one base plate and a main body, in particular a shelf or a shelf unit, which likewise ensures protection and good access to objects stored on or in the shelf or shelf unit. The furniture element will be developed further so that the support of the furniture element body on the base plate can be further improved and the furniture element located on the interference contour, such as a furniture element in a wall or corner, can be rotated. The body is a furniture part with a bottom and at least one closed side wall, behind which at least one storage element, for example a shelf, is arranged.

This object is solved by a furniture element having the features of claim 1 or a furniture having the features of claims 17 and 20.

The furniture element comprises a base plate arranged on a body of the furniture element.

The mutually facing bearing surfaces of the main body and the bottom plate have respective raceways in which the rolling elements are guided.

The body of the furniture element can be moved relative to the base plate from an initial position to an intermediate position and further to an open position and back.

In the intermediate position, the main body rotates in one rotational direction with respect to the base plate, and is displaced in a predetermined direction. In the initial position and the open position, the body coincides with the floor, i.e. it does not protrude beyond the dimensions of the floor, but the body is in each case rotated through 180 °.

In case the body in the initial position overlaps the bottom plate in size, or vice versa, the same state (same alignment/same overlap) is restored in the open position, except that the body is rotated by 180 °.

If there is more than one raceway, it is preferred that one of the two raceways of the base plate is designed to open towards the raceway that is open at one edge of the base plate.

In the case of a furniture element, the at least one raceway of the base plate is each formed mirror-symmetrically with respect to an axis of symmetry running at an oblique angle to the side edges of the base plate.

In the case of a furniture element, the at least one raceway of the bearing plate can additionally each be formed mirror-symmetrically with respect to an axis of symmetry running at an oblique angle to the side edge of the bearing plate.

Such a furniture element can be placed, for example, in a corner of a room, which furniture element consists of two side walls at an angle to one another and is swiveled out of this corner of the room in a simple manner, so that the furniture element is placed in an initial position, for example in such a way that the furniture element is covered by the side walls of the body, and is swiveled out of the corner, for example, in an open position through 90 ° or 180 °, so that a user can freely access at least one storage layer of the furniture element.

Such a furniture element according to the invention, which stands against a wall of a room or in a corner of a room, can be moved by turning from a position closed by a side wall of the furniture element body to an open position, while maintaining the same basic position.

Thus, the at least partially combined translational-rotational movement of the furniture element enables access to the contents of the furniture element in a simple manner. The ratio of translation and rotation in the overall movement may vary depending on the design of the raceway throughout the movement.

Unlike conventional furniture elements, there are no blocking doors, flaps or front panels in the entry position that could obstruct access.

Advantageous further developments of the invention are the subject matter of the dependent claims.

According to an advantageous embodiment of the furniture element according to claim 3, the axis of symmetry extends at an angle of 45 ° to the side edges of the base plate and/or the bearing plate.

In particular, this allows the furniture element to be rotated out of a right-angled corner of a room about an axis perpendicular to the raceway plane, wherein the furniture element performs a 45 ° rotational movement to the side edge of the floor plate in an at least partially simultaneous translational manner.

According to one embodiment variant, the base of the body has, on its side facing the base plate, a recess in which the bearing plate is fastened, at least one raceway being formed on the side of the bearing plate facing the base plate. Alternatively, the support plate may be formed integrally with the base of the main body.

This enables furniture elements which were not previously equipped with the possibility of a translatory-rotary movement to be easily assembled and, if necessary, retrofitted with such bearing plates and parts connected thereto to achieve such translatory-rotary movement.

According to a further embodiment variant, the raceway formed in the bearing surface of the main body is designed as a closed circumferential raceway and thus enables reliable guidance of the rolling elements.

Preferably, the bottom plate, the bearing plate, the rolling elements and the rolling element cage form a translation-rotation bearing. Such a translational rotational bearing may be provided in a kit and may in particular also be subsequently integrated into the base of the furniture element.

Preferably, the furniture element may have a body with at least one closed side wall. The body may be designed in such a way that in an initial situation the contents of the furniture element are hidden and thus a kitchen appliance such as a coffee maker or a water kettle may easily "disappear" when not in use.

This makes the design of the kitchen or other living room or studio or bathroom and its furniture very attractive. This is particularly beneficial in open space concepts and conference rooms.

According to a further embodiment variant, the body of the furniture element has a plurality of storage layers, so that the storage space of the furniture element is increased in a simple manner.

According to another embodiment, the rolling elements are captively accommodated in at least one rolling element cage, which is particularly advantageous for the mounting of the rolling elements between the raceways.

According to another embodiment variant, the other translation-rotation bearing is fixed to the cover of the furniture body. This makes it possible in particular to arrange such furniture elements in furniture, such as for example cooking islands, or also in corners of kitchen furniture structures which are open on both sides, for example. This ensures good travel performance of the furniture element and prevents it from tilting.

In particular, this arrangement has the advantage over the drawer of a pharmacist that by guiding the furniture element via two such bearings, simultaneous access of the furniture element in both bearings is achieved, in particular at the bottom and the top.

In such an arrangement of two bearings on a furniture element (also referred to as a "tandem arrangement"), it is important to maintain a proper ratio of the overall height or distance between the bearings to the diameter of the bearings or the curved track formed in the bearings. If this ratio is disadvantageous, for example, if the diameter of the bearings is small and the distance between the bearings is large, tilting easily occurs because it is not always possible to ensure that the upper and lower bearings are loosened at the same time.

In addition, a special linear guidance of the rolling element, as in the case of a pharmacist drawer, can easily lead to tilting of the furniture element. In contrast, the combined translational and rotational action reduces tilting because the rolling elements are guided over the entire surface.

According to a preferred embodiment variant, the raceways formed in the bearing plate form at least one outer raceway and one inner raceway.

According to a preferred further development, a third raceway is formed between the outer raceway and the inner raceway. Such a third raceway is used to perform further functions, such as in particular limiting the rotation of the furniture element. In this case, such a third raceway must also be formed in the bottom plate.

According to another embodiment variant, the fastening device is provided on the body of the furniture element for the vertical fastening of the base plate.

According to another embodiment variant, the base plate has a slot into which a guide sleeve projects from the underside of the base facing the base plate and thus guides the translational movement. This ensures a permanent connection between the bearing plate and the base plate, and thus the function of the bearing, in particular in the case of asymmetrical loading.

The furniture according to the invention comprises a body having a plurality of side walls and/or partitions and a cover. At least one furniture element as described above is arranged in the piece of furniture according to the invention.

Particularly preferably, the furniture element is arranged in a corner region of the furniture.

Particularly preferably, such a furniture element is arranged in at least two corner regions of the furniture.

Another piece of furniture according to the invention comprises at least two furniture elements according to the invention, which are arranged in series with the translation-rotation bearing as described above, and a cover plate covering the at least two furniture elements. This piece of furniture specifically avoids the use of rigid side walls or partitions to connect the base to the cover. The cover plate is therefore supported solely by the at least two furniture elements according to the invention, and the stability of the furniture is ensured by the built-in bearings of the at least two furniture elements. This makes it possible in particular to arrange such a furniture element in a piece of freestanding furniture.

In a preferred variant, a further piece of furniture according to the invention with a first body and a furniture element comprises a body which can be placed in a fixed position on a floor by friction.

Such a piece of furniture can be used, for example, as a table, in particular a desk, or also as a kitchen work table, wherein the furniture element can be moved relative to the stationary furniture body from a position in which the furniture element covers the body to a position in which the furniture element does not completely cover the body and the back, by means of a translation-rotation bearing relative to the stationary furniture body.

For example, in the open position, the furniture element may be aligned perpendicular to the fixed furniture body. The first lifting means may additionally be attached to the main body.

In this case, the furniture element can have a second lifting device which can be actuated synchronously with the first lifting device, wherein the translational-rotational bearing of the furniture element is mounted on the first lifting device.

Detailed Description

In the description of the drawings that follows, terms such as top, bottom, left, right, front, rear, and the like refer exclusively to the exemplary representations and locations of the furniture elements, bodies, raceways, floors, rolling elements, and the like that are selected in the various figures. These terms should not be construed restrictively, i.e., these references may vary for different working positions or mirror-symmetrical designs, etc.

In fig. 1 to 4, a first variant of the furniture element according to the invention is designated by the reference numeral 2.

In fig. 7 to 15, reference numeral 3 denotes an alternative embodiment variant of the furniture element.

In fig. 16 to 22, reference numeral 12 designates a further alternative embodiment variant of the furniture element.

The furniture element 2 shown in fig. 1 to 4 is designed by way of example as a shelf with a square base and three storage chambers.

The furniture element 2 comprises a body 22 having a base 23 and a plurality of shelves 25. The uppermost side of the shelf 25 here forms the top of the shelf, so that the shelf is designed to be closed at the top.

The body 22 of the furniture element 2 also comprises two side walls 24 which enclose the furniture element 2 from two sides.

The furniture element 2 further comprises a bottom plate 21, which is arranged on the main body 22, in this case on a base 23 of the furniture element 2.

The mutually facing bearing surfaces of the main body 22 and the bottom plate 21 have respective raceways 27, 28 in which rolling elements 51 are guided for a movable bearing of the main body 22 relative to the bottom plate 21.

In a first exemplary embodiment, according to fig. 4, the raceway 27 associated with the main body 22 is arranged on a support plate 26, which is fixed to the base 23 of the main body 22. However, the support plate 26 can also be an integral part of the base 23.

The rolling elements 51 are mounted in a rolling element cage 5, which in the embodiment variant shown here is designed as a square frame in which a total of eight rolling elements 51 (preferably designed as balls) are mounted.

Depending on the degree of surface pressure and thus the force acting on the rolling elements 51, it is conceivable to vary the number and/or diameter of the rolling elements 51 in order to obtain the desired surface pressure.

The rolling elements 51 are arranged in the corners of a rolling element cage 5, which is designed as a square frame, respectively for improved support of the main body 22 relative to the bottom plate 21. Four further rolling elements are placed centrally on the respective side faces of the rolling element cage 5.

Although the raceway 27 on the underside of the bearing plate 26 facing the base plate 21 is formed as a closed circumferential raceway, preferably two raceways 28 of the base plate 21 are each formed mirror-symmetrically with respect to an axis of symmetry which extends at an oblique angle, preferably 45 °, to the side edges of the base plate 21.

In the embodiment variant shown here, the axis of symmetry extends parallel to the side edges of the bottom plate 21.

One of the two raceways 28 is formed as a closed circumferential raceway. The second of these raceways 28 is designed in such a way that its ends open into the two side edges of the base plate 21 which are at an angle to each other and are thus designed as open raceways.

The choice of open and closed raceways therefore enables the furniture element 2 to be sufficiently stable both when at rest and during rotation of the furniture element 2, as long as the surface overlap between the base plate 21 and the body 22 of the furniture element 2 is at least 50% in each position.

If the surface overlap between the base plate and the body of the furniture element 2 is less than 50% in any position, more than one open raceway is required to ensure sufficient stability of the furniture element 2 at rest and during rotation of the furniture element 2.

In general, by varying the type and number of raceways, the orientation and positioning of the raceways with respect to the desired direction of translational movement, and optionally further supporting functional elements such as the fixing means 7 mentioned further below, a sufficient stabilization of the furniture element 2 is possible both when stationary and during rotation of the furniture element 2.

This design of the raceway 28 and the floor plate 21 enables the body 22 of the furniture element 2 to be rotated into a room corner 4, schematically shown in fig. 1 to 3, which corner comprises a base 41 on which the floor plate 21 of the furniture element 2 rests and two side walls 42, 43, which are aligned at right angles to one another here, wherein the two side edges of the floor plate 21 are positioned close to the side walls 42, 43, so that the furniture element 2 is positioned in its entirety in the room corner.

The raceway 28 in the base plate 21 and the raceway 27 in the bearing plate 26 and the rolling elements 51 arranged therebetween enable a rotation and a translation of the main body 22 relative to the base plate 21, which allows the furniture element 2 to be positioned in the corner 4 of the room in the initial position shown in fig. 1. At the same time, the furniture element 2 is closed, i.e. covered, by the side wall 24, which prevents access to objects stored in the furniture element 2 or protects them from dust or splashed water and gives the furniture element 2 an aesthetic impression.

By rotating the body 22 relative to the bottom plate 21 from this initial position, the furniture element 2 is opened, i.e. the side wall 24 of the body 22 is moved during rotation to a position in which the side wall 24 is arranged directly opposite the side walls 42, 43, so that objects stored in the furniture element 2 are now freely accessible.

The design of the raceways 27, 28 is such that the furniture element 2 can be positioned with its base 23 again in line with the bottom plate 21 in the open position shown in fig. 3.

Only in the intermediate position shown in fig. 2, the base 23 of the furniture element 2 is pivoted towards the floor panel 21.

To further stabilize the translational and rotational movement of the body 22 relative to the base plate 21 and to secure the base plate 21 to the body 22, the base plate 21 has a slot 29 that is aligned in the direction of the axis of symmetry of the raceway 28 of the base plate 21. A guide sleeve 71 projects into this slot 29 and is fixed by a screw 72 which projects from the base 23 facing the underside of the bottom plate 21.

The screw 72 is centrally positioned in the base 23 of the body 22 of the furniture element 2.

Other securing options are also contemplated, such as latching, clamping, pressing, gluing, screwing, and the like.

For use, the furniture element 2 located in the room corner 4 in fig. 1 can therefore also be moved out of the room corner 4 in the direction a and rotated substantially simultaneously by: about a vertical axis of rotation of which the position can be varied, from an initial position shown in fig. 1 in the direction of rotation M₁、M₂Rotated to the open position shown in fig. 3. In this case, the proportion of translation and rotation in the overall movement may vary throughout the movement.

As shown in fig. 5, in an alternative embodiment variation, a third raceway 28c is integrally formed in the base plate 21 and the support plate 26 in addition to the outer raceway 28a and the inner raceway 28 b.

Such a third raceway 28c enables a further translatory-rotational movement of the furniture elements 2, 3.

The third track 28c extends further radially inward in fig. 5 along a section of the outer track 28a from the start of the rotational movement, here for limiting the rotation of the furniture element.

To make this possible, the rolling-element cage 5 'shown in the middle of the three illustrations in fig. 5 is here approximately square, with slightly radially inwardly curved sides, which cage is formed with recesses for the rolling elements 51, which recesses are arranged in the outer corners of the rolling-element cage 5' for the rolling elements 51 that can move in the outer raceway grooves 28 a. These rolling elements 51 are arranged on the outer circle K₁The above.

A receptacle for further rolling elements 51 is formed integrally substantially centrally on the side of the rolling element cage 5', said rolling elements 51 being movable in the inner raceway groove 28 b. These rolling elements 51 are arranged on the inner circle K₂The above.

The rolling elements 51 guided in the third raceway 28c are arranged radially inside one of the rolling elements 51 arranged in a corner of the rolling-element cage 5'. The rolling elements 51 are arranged in a central circle K₃The above.

Circle K₁On the axis of symmetry SK of the rolling element arrangement 51₁Relative to circle K₂On the axis of symmetry SK of the rolling element arrangement 51₂Is inclined by 45 degrees.

As can be seen in the lower view of fig. 5, an inner raceway groove 27a and an outer raceway groove 27b, and another third raceway groove 27c, which is also formed further radially inward toward the rotation origin U with respect to a part of one of the outer raceway grooves 27b, are also integrally formed in the support plate 26.

As can be further seen in this figure, the raceways 27a and 27b are shaped about the axis of symmetry S₁(vertical here) and horizontal symmetry axis S₂And (4) symmetry.

Fig. 6 shows a further embodiment variant of a rolling-element cage 5, 5 ″ with rolling-element receptacles which are arranged in such a way that they are respectively arranged at the outer circle K₁And an inner circle K₂The above.

Fig. 7 to 15 show a further embodiment variant of the furniture element 3 according to the invention.

As shown in the exploded view in fig. 7, in contrast to the embodiment variant of the furniture element described on the basis of fig. 1 to 4, the pan-swivel bearing 6 is arranged in each case below the base 33 of the body 32 of the furniture element 3 and above the cover 31 of the furniture body 32 of the furniture element 3, with the upper bearing 6 arranged with the base plate 61 facing upwards.

In this case, the base 33 and the cover 31 form a cavity with an upper edge and a lower edge of the furniture body 32, in which cavity at least a part of the bearing 6 is accommodated.

The basic structure of the two bearings 6 is substantially the same as described with reference to fig. 1 to 4. In this exemplary embodiment, there is also a fixing device 7 with a screw 72 and a guide sleeve 71 and a rolling element cage 62 with rolling elements 66.

In this case, the bottom plate 61 corresponds to the bottom plate 21, and the support plate 63 corresponds to the support plate 26. In the application of the furniture element 3 shown in fig. 7, this element can preferably be used in a piece of furniture 8 as shown in fig. 8 to 15.

Fig. 8 to 15 show a piece of furniture 8, here for example a kitchen piece of furniture in the form of a cooking island. However, other places of use of such a furniture element 3 are also conceivable.

In order to adapt the base plate 61 of the pan-tilt bearing 6, which is fixed under the base 33 of the furniture element 3, to the height of the base of the other parts of the piece of furniture 8, a foot 68 is attached to the underside of the base plate 61 facing away from the raceway 64. These feet 68 can be designed to be adjustable.

The bearing plate 63 is preferably attached to the underside of the base 33 of the body 32 of the furniture element 3 facing the bottom plate 61. It is also conceivable here to machine the raceway 65 directly to the underside of the base 33 instead of the bearing plate 63.

Fig. 8 shows a piece of furniture 8 in the form of an island unit having a cover panel 81, several side walls 83 and a base panel 82, wherein the furniture element 3 is arranged in a corner in the closed state of the furniture element 3. The feet 68 are disposed behind the base panel 82.

Fig. 9 shows the furniture element 3 in a slightly open position, fig. 10 shows the furniture element 3 in an almost fully rotated open position, and fig. 11 shows the furniture 8 with the furniture element 3 fully open.

In fig. 12, the piece of furniture 8 is again shown in broken lines to show the furniture element 3 mounted in the piece of furniture 8 below the cover plate 81.

Fig. 13 to 15 show possible embodiment variants of a piece of furniture having one furniture element 3 (fig. 13), two such furniture elements 3 (fig. 14) and four such furniture elements 3 (fig. 15). When a plurality of furniture elements 3 are arranged, preferably only one common cover 81 is used.

Fig. 16 to 22 show a further embodiment variant of a piece of furniture 10 according to the invention, which has a furniture element 12 that can be moved in translation and in rotation relative to a furniture body 11 that is fixed or frictionally mounted on a room floor.

As shown in particular in fig. 16 and 20 to 22, the piece of furniture 10 is designed as desk furniture or as kitchen island or kitchen table or the like, having a furniture body 11 which is fixedly placed on the floor of a room and a furniture element 12 which can be moved translationally and rotationally relative to the furniture body 11.

As shown in fig. 17, 21 and 22, the furniture body 11 comprises a receptacle 112 in the central region of the work surface 111 for accommodating the first lifting device 13.

The lifting device 13, which is designed here as a telescopic lifting device, is accommodated in the receptacle 112 of the furniture carcass 11, wherein the telescopic elements 131, 132, 133 can be moved upwards out of the receptacle 112.

A support plate 134 is mounted uppermost of the telescopic elements 133. A bottom plate 91 of another embodiment variant of the pan-swivel bearing 9 is mounted on the support plate 134.

As shown by way of example in fig. 17, the furniture element 12 has a body 121 with an operating face, to the base of which the bearing plate 93 of the pan-swivel bearing 9 is attached.

A side part 122 is arranged, in particular fastened, at one end of the body 121, which side part 122 has a central receptacle for accommodating the second lifting means 16.

The structure of the second lifting means 16 preferably corresponds to the structure of the first lifting means 13, i.e. it also has a first, a second and a third telescopic element 161, 162, 163.

A foot 165 with at least two rolling elements 166 is arranged on the lowermost first telescopic element 161 of the lifting device 16.

The side portion 122 thus serves as a second supporting leg of the furniture element 12 for the lifting device 16 arranged thereon.

The furniture element 12 is therefore supported on the one hand by the side portions 122 and the second lifting means 16 arranged thereon and via the first lifting means 13.

The lifting device 13 thus supports the body 121 of the furniture element 12 via the translation-rotation bearing 9 accommodated therebetween.

The furniture element 12 can thus be moved from an initial position shown in fig. 16, in which the furniture element 12 completely covers the furniture carcass 11 here by synchronous actuation of the lifting devices 13, 16, into an open position shown in fig. 20, by means of which the furniture element 12 can be lifted relative to the furniture carcass 11.

In the open position, the upper side of the body 121 of the furniture element 12 (here used as a work surface) is aligned perpendicular to the work surface 111 of the furniture body 11. Other open positions are also contemplated. Depending on the orientation and embodiment of the pan-swivel bearing 9, the furniture element 12 can be moved by a greater or lesser angle, for example 180 °.

The arrangement of the pan-swivel bearing 9 on the supporting plate 134 of the first lifting device 13 is such that when the furniture body 11 is located in a corner of a room, the furniture element 12 can be moved from the position shown in fig. 16 to the position shown in fig. 20 without the furniture element 12 projecting beyond the rear edge of the furniture body 11 during the movement. This is particularly advantageous when the furniture body 11 is arranged against a wall or in a corner.

The pan-swivel bearing 9 shown in fig. 17 is shown in detail in fig. 18 and 19.

As fig. 18 and 19 show, the base plate 91 also has, on its bearing surface facing the bearing plate 93, a raceway 94 for guiding the rolling elements 51, here in the form of balls.

The rolling elements 51 are also captively received in the rolling element cage 92. As in the embodiment variant shown in fig. 7, the rolling element cage 92 is circular, with several arms extending radially outwards.

Here, too, the guide channel 97 is centrally and diagonally arranged on both side edges of the bottom plate 91, which are aligned at right angles to one another.

The guide carriage 151 is displaceably mounted in this guide channel 97.

The guide carriage 151, which is part of the fastening device 15, comprises, on its upper side facing the support plate 93 or the body 121 of the furniture element 12, a support neck 152 which projects into the opening 99 in the support plate 93, which support neck is preferably integrally formed on the upper side of the guide carriage 151.

Said bearing neck 152 serves as the axis of the rolling bearing ring 157 (in particular a ball bearing ring) inserted into the opening 99 (preferably in the form of a hole) of the bearing plate 93, by means of which low-friction rotational movement of the bearing plate 93 relative to the guide carriage 151 and thus relative to the base plate 91 is possible.

A roller bearing with at least two rollers 154 arranged one after the other in the longitudinal direction of the guide channel 97 is arranged, in particular fastened, on the underside of the guide carriage 151 facing away from the bearing plate 93.

Each of these rollers 154 has a circumferential V-shaped groove 155 in which V-shaped webs 95 projecting from opposite side walls of the guide channel 97 form running faces of the rollers 154.

The V-shaped groove 155 of the roller 154 is guided in the guide channel 97 along the V-shaped web 95, producing an extremely stable and constant sequence of translational-rotational movements of the furniture element 12.

In addition, a push-moving mechanism in the form of an ejector element 14 is shown in fig. 18, which mechanism comprises an accumulator 141 and a plunger 142 and is arranged in the guide channel 97 in order to eject the furniture element 12 after unlocking in the direction of movement.

The use of such a push-movement mechanism makes it possible to specifically design a furniture element without an actuating handle and initiate an opening movement of the furniture element by pushing it against the intended opening direction. It is also conceivable to use an ejection mechanism which can be activated in another way.

Alternatively, the piece of furniture can also be designed as desk furniture or as a kitchen island or kitchen work bench or the like, without the need for further second lifting devices on the furniture element 12. In this case, the furniture part which is movable in a translatory-rotary manner is supported solely by the first lifting device arranged on the stationary furniture body.
