Technical Field

The invention relates to a platform with legs and supports on the legs, wherein the supports are pivotably connected to a mounting of the legs by means of a pivot axis and are operatively connected to one another in such a way that a pivoting of one support causes a pivoting of one or more other supports which are operatively connected, wherein the operative connection is achieved by force transmission by means of a transmission between the supports.

Background

Pedestals of the type described are known. The stand preferably has a central leg, which extends in the use position in a vertically oriented manner, from which a support is articulated on the foot side for the purpose of bearing on the floor or the like, said support projecting substantially radially outward with reference to the geometric longitudinal axis of the stand leg or the stand leg and, furthermore, with reference to the plan shape or plan view of the stand, in which the geometric axis is represented as a point. For this purpose, preferably four or more, for example five or six, brackets can be provided, more preferably at even circumferential distances from one another.

In order to be able to stand the stands stably even on potentially uneven ground, known solutions provide for an operative connection between the supports by force transmission, so that the deflection of one support about a deflection axis oriented preferably transversely to the geometric longitudinal axis of the table leg for adapting the stand to a given ground surface adapts the deflection position of the other support by the operative connection.

In connection therewith reference may be made to patent document EP 2515713B 1.

Disclosure of Invention

In view of the prior art described above, the object of the invention is to further develop a stand of the type described.

A possible solution to the stated problem is provided according to a first inventive concept relating to a stand in which the transmission arrangement has a transmission section which is movable relative to the two supports.

In one possible embodiment, the transfer section can preferably be arranged movably in the region of the fastening of the leg. This may be, for example, the slidability of the transmission section, by means of which the movement of at least one carrier can be transmitted to at least one other carrier, but if necessary also to all other carriers.

Through a transmission structure, it is necessaryThe specific design of the transmission section allows a reduction (german: untersetzong) or an increase (german:)。

further features of the invention are generally set forth below and in the description of the figures in their preferred configurations with respect to the solution of claim 1 or the features of the other claims. The further features may, however, also be of significance only with respect to claim 1 or with respect to individual features of the respective further claim or independently of one another.

The transmission can thus have a deflection region in which a change in direction of the force transmission can be achieved without directly interacting with the carrier. The direction of movement of the first transmission member may extend at an angle, preferably at right angles (90 degrees), to the direction of movement of the second transmission member, e.g. the transmission section. An acute angle of less than 90 degrees, for example 45 degrees, or an angle of more than 90 degrees, for example to 135 degrees, may also be enclosed.

The change in direction of the force transmission is accompanied by a change in direction of movement, wherein the change in direction can also be produced several times in its entirety by the transmission section between the two supports.

In one possible embodiment, a first direction of movement of the first transmission section, which is oriented substantially approximately parallel to the geometric longitudinal axis of the table leg, and a second direction of movement of the second transmission section, for example of the transmission section, in a direction viewed transversely to the first direction of movement are produced, so that a change in direction of force transmission can produce a change in direction of movement from vertical to horizontal or from horizontal to vertical when the geometric longitudinal axis of the table leg can be oriented precisely vertically.

The transmission structure enables the use of the fastening element for the support independently of the force application in the axis of rotation. The fastening element can provide guidance for the transmission structure, in particular the transmission element, and the transmission section.

In one possible embodiment, the two brackets in operative connection can only indirectly abut against each other via the transmission. The force transmission between the two supports can preferably take place exclusively via the transmission.

In other embodiments, the support can have a radially outer end and a radially inner end with reference to the geometric vertical center axis of the table leg. The two operatively connected carriers can thus interact with the transmission structure in the section of the radially outer end of the carriers, in each case with reference to the rotational axis of the carriers. The interaction of the carrier with the transmission structure accordingly preferably takes place only in a limited region, if appropriate only in a punctiform or linear manner. In a preferred embodiment, it is furthermore provided that all the supports of the stand which are in operative connection are of substantially identical design and act on the transmission structure in the same manner.

The radially inner ends of the struts which are in operative connection with one another can be kept at a distance independently of the deflection position between the end positions. In a preferred embodiment, it is therefore provided that the two supports which are in operative connection with one another do not bear directly against one another, irrespective of the deflected position in which the supports are in the deflected position.

The radially inner ends of the struts which are in operative connection with one another can still be stopped in one or both end positions. Thus, the region of the support associated therewith can cooperate with the region of the fastening element to define the deflection end position.

The drive mechanism can preferably be a wedge mechanism, wherein the wedge mechanism preferably has two vertically movable and one horizontally movable drive element for the operative connection between the two supports with reference to the normal use position of the table leg, wherein the wedge mechanism furthermore preferably connects all supports in operative connection for the action of the mutual forces. The vertically and horizontally movable transmission elements interact via a wedge surface, wherein the horizontally movable transmission elements are preferably transmission segments. The wedge surfaces of the vertically movable transmission part and the directly connected horizontally movable transmission part can thus lie flat and flat against one another, wherein the wedge surfaces preferably essentially represent an angular bisector between the directions of movement of the vertically and horizontally movable transmission parts.

A vertical downward movement of the transmission element by means of the wedge surfaces correspondingly leads to a horizontal movement of the other transmission elements, in particular of the transmission sections, and vice versa.

Each support preferably acts on a vertically movable transmission element or is influenced by a vertically movable transmission element in terms of the deflected position of the support. Between two supports which follow one another in the circumferential direction of the table leg, a horizontally movable transmission element in the form of a transmission section is arranged between the respectively associated vertically movable transmission elements.

This results in a preferably closed loop-like structure of the wedge mechanism. This loop-like design is particularly suitable for the overall wraparound effect. A geometrically circular arrangement is not necessarily specified. Instead, a closed loop-like structure can be defined in a polygonal manner, for example in a square manner when four supports are arranged, with reference to the projection in the horizontal plane.

Detailed Description

First, with reference to fig. 1, a table 1 with table legs 2 on which a table plate 3 is arranged is shown and described.

A pedestal 4, which in the embodiment shown has four supports 5, is formed on the table leg 2 facing away from the table plate 3.

With reference to a central axis x of the table leg 2, which is geometric and perpendicular in the normal use position of the table 1, the supports 5 extend radially to the outside with reference to a planar shape in which the central axis x appears as a point, wherein the supports 5 can also have the same distance from one another, viewed in the circumferential direction.

In the exemplary embodiment shown, the support 5 is essentially formed by a support carrier 6 and a support shield 7 fastened thereto, which is only visible when the table 1 is in normal use.

The support 5 is pivotably connected to a mounting 8 of the leg 2. The fastening element 8 provides a housing for this purpose, which has a fastening element cover 9, a fastening element wall 10 which is surrounded with reference to the center axis x, and a fastening element cover 11 which can be mounted on the underside.

The support body 6 of the support 5 extends in an angular direction with reference to the plan shape of the arrangement. Each support carrier 6 therefore has first of all a plate-shaped holding section 12, to which holding section 12 a fastening section 13 is connected at the end face, enclosing an obtuse angle of, for example, 135 to 150 degrees with the holding section 12. The fastening section is likewise of substantially plate-like design, and has a height, viewed in the use position along the direction of extension of the central axis x, which exceeds the material thickness, viewed transversely thereto, by a factor of approximately three to six.

The bracket shield 7 in the form of a flap can be fixed to the fastening section 13.

The carrier support body 6 extends with its holding section 12 in the fastening element 8, where it passes through the fastening element wall 10 approximately in the transition region to the fastening section 13 in the region of the slot-like recess 14. The fastening section 13 thus extends substantially beyond the fastening element 8.

The support 5 and thus the support carrier 6 and the support shield 7 are of identical design.

Each support 5 is held on the mount 8 by a holding section 12 so as to be pivotable about an axis of rotation y. The axis of rotation y extends transversely to the center axis x and is formed by the geometric center axis of the screw 15, which passes through the fastening part wall 10 and the retaining section 12 in the radial direction with reference to the center axis x.

The axial free height of the fastening means 8 between the fastening means cover 9 and the fastening means cover 11 and the height of the support body 6, viewed in the same direction, in particular in the region of the holding section 12, are selected such that a deflection of the support 5 with its support body about the axis of rotation y can be achieved, preferably with limited stops.

On the one hand, a stop limit can be produced by the fastener cover 11 against which the holding section 12 can rest in the end-of-deflection position. The other end positions of the deflection can be limited by stops relative to the fastening section.

The active connection causes a deflection of the support 5 simultaneously or likewise a deflection active connection of the other supports 5. This operative connection is achieved by force transmission by means of the transmission structure G between the brackets 5.

The drive mechanism G is in the exemplary embodiment shown designed as a circumferentially closed, endless wedge-shaped mechanism 26, which has a first drive element 16 that is movable substantially vertically in the normal use position of the table leg 2, said first drive element being adapted in number to the number of supports 5. In the case of four carriers 5, four first transmission parts 16 of a transmission arrangement G are respectively provided in the corner regions, which in the present exemplary embodiment is of substantially square design in the planar shape according to fig. 7. A second transmission member 17, which functions as a transmission section 18, which is horizontally movable, extends between the two first transmission members 16.

Each transfer section 18 or each second transmission element 17 is provided with a wedge surface 19 on the end side and facing the associated first transmission element 16. The wedge surface extends at an angle of preferably approximately 30 to 60 degrees, further approximately 45 degrees, with respect to the sliding surface of the second transmission part 17, with reference to a longitudinal section according to the illustration in fig. 12.

The wedge surface 19 is configured for co-action with a mating wedge surface 20 on the first transmission member 16. The first transmission part 16 has two mating wedge surfaces 20, respectively, which are offset by 90 degrees in plan view.

The aforementioned transmission structure G is fixed in a shell-like transmission housing 21, wherein, in the elevation position of the transmission structure G (german:) The gear housing 21 can be closed off in its entirety from the underside by a corresponding cover 22, as shown in fig. 12. Only the first transmission part 16 can project unhindered vertically downwards through the cover 22 and thus bear on the facing, vertically upwards-directed end face of the respectively associated retaining section 12 of the carrier 5.

As can be seen, for example, from fig. 6, each transmission member 16 has a continuous, planar stop face 27 toward the holding section 12. The contact surfaces produced in this case can extend in a direction oriented exactly transversely to the direction of movement of the transmission element 16.

The contact surfaces can alternatively also be designed in a stepped manner according to the view of fig. 8, for example with a planar step portion 28 and a protruding portion 29 protruding relative to the step portion 28.

In the area of the planar mutual overlap of the wedge surface 19 of the second transmission part 17 and the mating wedge surface 20 of the first transmission part 16, a deflection area U is created, in which a change in direction of the force transmission can be achieved without direct interaction with the carrier 5.

The ends 24 of the support 5 or of the support carrier 6 radially inside with reference to the center axis x are designed independently of the deflection position of the support 5, so that the distance a is always maintained between the ends.

In the region of the radially outer end 23, the carrier 5 interacts with its holding section 12 with the transmission structure G. This bearing structure is not relevant for the bearing of the force in the axis of rotation y or the bolt 15.

The transmission section 18 forming the second transmission member 17 is movable relative to the carrier 5 directly in active connection via the transmission arrangement G.

The function of the stand 4 is essentially as follows: fig. 12 shows a stand deflection position in which, when stand 5 is supported on ground 25, stand 5 or stand support body 6 of the stand encloses an acute angle α with the horizontal.

The first associated gear part 16 is supported by its contact surface 27 on the radially outer end 23 of the holding portion 12 on the holding portion 12. With the wedge surfaces 19 resting against the counter wedge surfaces 20, the second transmission part 17 or the transmission section 18 is displaced horizontally into the corresponding position, which in turn allows the first transmission part 16 following in the direction of the action circuit (wirkreischtung) to be vertically lowered into the transmission housing 21 while keeping the counter wedge surfaces 20 of the first transmission part resting against the facing wedge surfaces 19. This results in a deflection position of the respective support 5 assigned to the transmission element 16 or of the support carrier 6 of said support, in which the respective support 5 is deflected out of a horizontal plane E that is tangent to the axis of rotation y in the preferred embodiment. In this position, the other holders 5, which are offset by 90 degrees in plan view, enclose numerically the same angle with the horizontal plane E, as the holder 5 descends in fig. 12.

The operative connection of the supports 5 takes place over the entire circumference of the transmission G, correspondingly over all the supports 5, wherein in a preferred arrangement of four supports 5 two directly opposite supports 5 are each deflected or deflected by the transmission G in the same direction by the same amount with reference to the horizontal plane E.

Fig. 13 shows the changed deflected position of the support 5 relative to fig. 12. The stand 5 is raised according to the respective ground orientation, the line intersecting the axis of rotation y and the current line enclosing an acute angle α above the horizontal plane E with respect to the horizontal plane E.

The respectively associated first transmission part 16 is moved perpendicularly by the holding section 12 of the carrier 5 in the direction of the transmission housing 21 (arrow c). A horizontal sliding movement (arrow b) of the transmission section 18 or of the second transmission member 17 in the direction of the other first transmission member 16 in active connection is thereby formed. The further first transmission part 16 is raised by means of a wedge surface and a counter wedge surface (arrow c'), and accordingly projects further downwards out of the transmission housing 21 under a corresponding load of the respectively associated holding section 12 of the further carrier 5. The other support 5 is preferably lowered by the same angle in the case of a corresponding raising of the support 5 shown in fig. 13 due to a corresponding deflection (arrow d) about the axis of rotation y.
