Collapsible trestle Priority: France of March 9, 1973 No. 73 09 643

The innovation concerns a fully collapsible trestle, which is very small in the collapsed position Has dimensions.

The well-known trestles, for example for supporting table

ι · ♦ ·

or worktops, are generally made up of four solid, formed with a cross member connected legs. Such trestles generally consist of swsi Bsinp & srsr., Which sit two cross members are connected by suitable devices, such as hinges, for collapsing.

However, as a result of these prior art blocks, they are only partially collapsible and also in the collapsed State take up a relatively large space, handicaps in terms of transport and classification.

The present innovation has set itself the task of «creating a goat that does not have these disadvantages, because it is completely collapsible and in the collapsed State takes up very little space.

To solve the set up; abe will according to the innovation a collapsible trestle of the type mentioned is proposed, which is characterized in that it is essentially formed by four legs or feet which are connected to one another via a cross member and can be folded up along this, with the legs or feet in

the collapsed position to each other, two on each side of the cross member.

In order to enable precise folding, the trestle also has wedges, according to the innovation serve to spread the legs or feet and which are arranged on both sides at an outer end, with the Connection point each a plate of essentially the same Thickness as that of a leg or foot is intended.

According to another characteristic of the innovation, the

Legs or feet bolted and manually operated Nuts tightened.

The subject of the innovation is to be explained in more detail using the example of a preferred embodiment with the aid of the drawing will.

In the drawing shows

Fig. 1 is a plan view of a collapsed trestle according to the innovation.

Fig. 2 shows a side view in the direction of the arrow Fl of the erected trestle.

Fig. 3 shows a side view in the direction of arrow F2 of the stand erected according to the innovation.

Fig. 4 shows a side view of a leg part.

As can be seen from Fig. 1, the block according to the innovation consists essentially of a cross member 1 on which four legs or feet 2 are attached. They become legs in pairs in the erected or collapsed position each with a screw bolt 5 and one that can be actuated by hand Nut tightened.

As can be seen from Fig. 2, the spreading apart of the legs 2 to achieve a good stability by intermediate layer an angle 6 between each leg and the traverse 1 obtained.

To the buck exactly with a minimum of space To be able to collapse, the legs 2 must overlap.

For this purpose there is one at an outer end of the cross member 1 between this or the wedge 6 and the legs 2 Plate 3 of a thickness * which is at least equal to or a little larger than that of a leg 2 is placed (see Fig. 3). The legs 2, the traverse 1, the wedges 6 and the plates 3 can be made of wood, glass fiber reinforced Plastic, metal, plywood or some other material.

The plate 3 and the wedge 6, which are arranged on each side of the traverse 1 at an outer end thereof, can advantageously also be replaced by a single piece.

Fig. 4 shows a side view of a part of a leg 2, which on the inside rosette-like elevations 8 and Has recesses 7, which when tightening the two prevent rotation with respect to the cross member 1.

The buck according to the present innovation can due to its low Ruuabeanspretzung in the collapsed Condition can easily be transported in small vehicles, where-

the subject of the innovation makes it a particularly interesting use in various building trades, in particular by painters and decorators.

For use, two trestles can be set up and a table or worktop placed over them. Finally you can the trestles can also be used in schools and day-care centers used by school and gaming tables. However, the scope is not limited to the areas shown, but can extend to all other areas where such a buck either alone or is required in combination with several.

Furthermore, the innovation is not limited to that in the drawing

and the embodiment shown in the description is limited.

There are changes, especially with regard to the *

construction within the scope of the following claims, bow lair, without that the framework of innovation is left.

Claims (5)

PIAIA, Jacques, ',.',:!. '; "; ' (Protection claims 1. Collapsible block, characterized in that it is essentially formed by vicsr legs or feet which are connected to one another via a cross member and can be folded up along this, the Legs or feet in the folded position lie next to each other in 3 pairs on each side of the cross member. 2. Bocic according to claim 1, characterized in that the legs or feet together in the collapsed position due to an intermediate piece of the same thickness as one of the legs, which at the connection point has a outer end of the cross member between a foot and on both sides of the cross member is provided, and that the spreading of the legs to obtain good stability of the block is ensured by the arrangement of wedges (6) on both sides of the cross member. 3. Bock according to one of claims 1 and 2, characterized shows that the wedge (6) and the flat bar (?) consist of a single piece. 4. Bock according to one of claims 1 to 3, characterized in that the legs in pairs by means of a Screw nut (5) and a nut that can be operated by hand are tightened. 5. Bock according to claim 4, characterized in that the nut (4) as a wing nut, knurled wheel, as a lifting nut or is designed in another form which enables manual operation.
