Definitions
- the invention relates to a lock for a pivotable table leg attached to a table top, which one pivotable about an axis on the table top Hand lever to release the locking device for pivoting of the table leg in a position parallel to the plane of the Has tabletop.
- Such detents are general known and in use.
- table legs When tables are transported in motor vehicles or at When not in use, they should be kept to save space then you often provide them with removable or table legs pivotable towards the table top. Swiveling So far, table legs have been provided with struts, which from the table legs diagonally up to Guide the table top and thereby the respective table leg in fix the swiveled position. The lock then serves to loosen these struts so that the table legs can then be pivoted. Despite such Striving often creates the problem that the Table legs less rigidly connected to the table top are as table legs firmly attached to it. The table then tends to vibrate.
- the struts that stabilize the table legs the disadvantage that they are cumbersome when using the table because, for example, the armrests of chairs collide with the struts when you see such chairs want to push under the table. Even when sitting on one Table with such struts can be annoying.
- the invention is based on the problem of a lock for a pivotally attached to a table top Design the table leg so that the table leg is locked in place Condition as rigid as possible even without struts the table top is connected.
- Such a table leg can be swung out can be clamped to the table top without play, without the space below the table top is narrowed. Since the locking is done by means of a wedge when locking, dimensional deviations between the fixed stop, the cam and the support of the clamping wedge balanced, so that the locking device according to the invention are manufactured with low manufacturing accuracy can. If you provide the cam on the cross tube, then needed one lock for every two table legs. However, it is also possible to have each table leg individually and to be stored independently and one cam for each table leg and to provide a lock. Thanks to the backlash-free Clamping the table legs can be done on the previously the struts required to swivel the table legs.
- the hand lever and the clamping wedge can also be used with immediate Force transmission into the base plate as a single Component are formed when the edge surface of the recess curved concentrically to the axis of the hand lever runs and the clamping wedge in one piece with the hand lever and is sickle-shaped.
- the clamping wedge and the hand lever are separate parts. This is possible if according to another training the invention, the edge surface of the recess runs straight and the clamping wedge through a joint with play transverse to a direction of displacement with the hand lever connected is.
- the table legs move automatically after swiveling up tensioned when the clamping wedge is loaded by a spring in the clamping direction is biased.
- the locking is particularly simple and space-saving formed when the spring is a semicircular curved, with its free end against the clamping wedge Leaf spring is.
- a swiveling of the clamping wedge in This would result in a clamping position with the table leg swung in cause the clamping wedge when swiveling the table leg up is in the way of the cam of the table leg. Therefore the locking mechanism may only be used when the Move the table leg into its locking position. That leaves achieve themselves particularly simply by the fact that the free End of the clamping wedge in a transverse to the plane of the clamping wedge Direction of movement of the cam when swiveling the Has table leg extending guide surface.
- Tables with swiveling table legs often have cross tubes on which each have two table legs together connect and pivot each in two main bearings are stored. With such tables you can bend the cross tubes by locking in a simple way reliably exclude if in addition to the main bearings on each base plate another bearing for the Cross tube is arranged.
- FIG. 1 partially shows a table top 1 with a Table leg 2.
- the table leg 2 is non-rotatable with a Cross tube 3 connected, which in at the bottom of Table top 1 fastened main bearings 4 rotatably and two opposite table legs 2 with each other connects.
- a base plate 5 is fixed with a recess 6. In this recess 6 protrudes upwards from the Cross tube 3 projecting cam 7, which in the illustrated, pivoted position of the table leg 2 against an adjustable fixed stop 8 is present.
- a clamping wedge 9 is also located within the recess 6 arranged in the clamping position with a wedge surface 10th presses the cam 7 against the fixed stop 8.
- On this Wedge 9 is an L-shaped guide body 11 welded.
- Figure 2 shows that in addition to that the bottom of the table top 1 attached main bearing 4 a bearing 17 is arranged on the base plate 5, which the cross tube 3 is as close as possible to the cam 7.
- FIG. 2 also shows that on the base plate 5 a hand lever 13 is pivotally mounted by means of an axis 12 is.
- This hand lever 13 is a game by means of a having joint 14 connected to the clamping wedge 9.
- the clamping wedge 9 lies against an edge surface 15 of the recess 6 and is straight on this edge surface 15 slidable. As shown in Figure 2, it shifts above, then he presses increasingly with his wedge surface 10 against the cam shown in dash-dotted lines in FIG 7, so that this between the fixed stop 8 and the wedge surface 10 is clamped.
- the guide body 11 has on its downward Leg a guide surface 16.
- a spring 18 of the clamping wedge 9 is arranged in the clamping direction, which is a semicircular curve Leaf spring acts, which with one end on the base plate 5 is attached and with its other end in Figure 2 seen to the right of the joint 14 against the clamping wedge 9 is present.
- the spring 18 tensions the clamping wedge 9 in primarily in the clamping direction.
- the clamping wedge is 9 Crescent-shaped and integrally formed with the hand lever 13.
- the edge surface 15 extends to the axis 12 curved in an arc.
