Folding table

The innovation relates to folding tables, the legs of which can be swiveled under the table top so that the tables can be stacked.

In known folding tables, support fittings are known which consist of slot guides and corresponding, guided therein 0 rods exist. However, this results because of the large number of individual parts and articulation points and because of the relatively great length the linkage a rather unstable locking of the table legs, so that the table tends to wobble.

The innovation is based on the task of creating a folding table with a locking fitting that has few individual parts and simple structure, a play-free locking of the table legs in the unfolded position and a secure stand of the table guaranteed, with a very flat design in the folded state and thus an extremely space-saving Stapelu Tables is made possible.

According to the latest innovation, this is achieved * by means of locking fittings, which are mounted pivotably about an axis running perpendicular to the pivot axis of the legs and with the legs unfolded enter into a backlash-free locking connection with a cross member of a pair of the same. The locking devices are expediently

Schlag Mounted and stand in adjustable bearings without play when opened under the action of a spring.

In one embodiment of the innovation, each locking, locking fitting a plate with a V-shaped incision on- --- * show that the crossbar of a pair of legs in the unfolded position * "·, · absorbs play-free and self-locking. This plate of the locking fitting can be made to collapse in. '

position through the cross bar against the force of the spring down-c! is held. The cross bar can act directly on the plate.

In a further embodiment according to the invention, the Locking fitting has a bolt with a conical tip which engages in a groove in the cross bar in the unfolded position.

Depending on the design of the locking fitting and / or the transverse spar, the transverse spar can be attached to an approach of the locking fitting attack to hold the latter down in the folded position.

The innovation will now be described with reference to the drawing showing them for example, namely shows

Fig. 1 shows a view from below of one end of a table in the area of a locking fitting 1, which consists of a bracket 3 attached to the table top 2 with point bearings 4 and a plate 5 which is mounted in the point bearings 1 about an axis aa, which runs perpendicular to an axis bb about which a pair of table legs 6 is pivotably mounted in bearings 7 * ... The bearings 7 _t ^di © can be made of metal, plastic or * ··· wood and accommodate the ends of a cross member 8 of the table - *** · "legs 6 with little play, are also on the underside,". the table top 2 attached. The plate 5 has a V-shaped "··· notch 9» which, in the unfolded state (see Fig. 2), receives the '"· cross member 8 without play and in a self-locking manner, so that this'

and the table legs 6 are held steady. The top camp 4

can also be replaced by another adjustable, zero-play bearing. are set.

The plate 5 is under the action of a torsion spring 10, which tends to move the plate 5 in the direction of the arrow in fl. 2, i.e. to press into the unfolded or locked position. The arrangement is such that the angle that the plate 5 forms with the table top 2 in the unfolded position, remains below 90 °. To fold in the table legs 6, the plate 5 is pushed back against the action of the spring 10 by hand. As a result, the self-locking retaining connection between the plate 5 and the cross member 8 is canceled. The plate 5 is designed so that it cannot pivot past the transverse bar 8 in any position. It is therefore also in the folded state held by the cross member 8 as long as the table top 2 is down in accordance with the stacking position (see FIG. 5). The cranked training of the cross member 8 ensures the pre-frustrated operative connection with the plate 5 of the locking fitting 1.

In order to achieve a backlash-free storage of the plate 5, is one of the tip bearings 4 is designed to be adjustable by means of a screw 11 and a lock nut 12.

Fig. 3 shows an embodiment which differs from that of Figs. 1 and 2 through a different design of the table legs 6 ¹

and of the cross member 8 · differs. In this embodiment, the table legs 6 ^{1 are pivotably mounted in bearings 7 1} with inwardly protruding bearing journals 13, which each consist of two parts placed one on top of the other. The locking fitting 1 is essentially the same as that of the Pign. 1 and 2. It we.isfc on also the plate 5 which in the top bearings ¹ I gelagert'Ys, t and has the V-shaped notch. 9 So that the plate 5 '>' can interact with the transverse spar 8 ¹ in the manner described above, it has an attachment I ^ which always rests on the transverse spar 8 ·. It should be expressly pointed out that the shape of the table legs or pairs of legs can be any, if only one

fitting 1 is guaranteed. ;

The one in Pig. Ί illustrated embodiment, "in which the table legs 6 ', seen from the bearings 7', sit on the outside, the locking fitting 1 has a bolt 15 with a conical tip 16 instead of the plate 5, which in the unfolded position in a corresponding conical groove 17 engages in the cross bar 8 "without play and in a self-locking manner. On the bolt 15, the same approach 1Ί as in Fig. 3 is provided so that a corresponding operative connection, as described, with the cross member 8 ^{lf is} possible. Instead of the bolt 15, a plate with a single point can also be provided, which corresponds to the point 16 and the groove 17 can pivot into ν.

In Fig. 5, to which reference was already made in the preceding description, sections of two tables stacked on top of one another are shown, which are stacked with the table top 2 facing downwards, which here has a circumferential edge 18 protruding downwards in the position of use and upwards in the stacking position which, however, does not necessarily have to be present. 5 shows that the bearings 7 ¹ protrude beyond the circumferential edge 18, so that the table tops 2 each rest on the bearings 7 'and 7 of the table below. In order to avoid scratching the table tops 2, the bearings 7 or 7 'have a felt covering 19 or the like (see also FIG. 2).
