Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a console or bracket, in particular for constructing furniture on a metal support.

The invention also relates to a method of making such a console and furniture including it.

In particular, the console providing a rigid fixation of each corner of the shelf to the furniture leg comprises a substantially flat hexagonal plate (5) which receives the corresponding corner of the shelf. This plate is oriented transversely to the leg in the position of use. This hexagonal plate has a molded knurl at one of its vertices adapted to match the cross section of the molded piece of the leg. A reinforcing bracket is attached to this hexagonal plate. These reinforcement brackets are made of approximately six hexagonal plates.
It is constructed with square side pieces. This side piece is
For example, on either side of the plate, it is folded back, or to form a flange, by being folded laterally following the intersection angle that the recessed top makes with respect to the plane of the plate. Each reinforcing bracket has a supporting edge transverse to the folding angle and forms a molded recess in the plate so that it rests on the leg parallel to the generatrix of the leg in the console's position of use.

The construction of this console consists of cutting out a sheet metal material having a shape corresponding to the desired shape of a triangular plate with a recessed top and two approximately hexagonal side pieces;
forming a flange on said hexagonal plate by bending its two side pieces transversely to the plane of said plate (6) following the intersecting angle forming the recess in said top; consists of things.

The above-mentioned console, for example, was released in 1974
French patent application no.
From French Patent Application No. 74-43115 dated May 27, 2007, i.e. French Painting JIq Patent Application No. 2.295,714 (known from French Patent Application No. 74-43115, French Patent Application No. 2.295,714), this console is particularly useful when constructing metal furniture. This gives good results when forming a metal table consisting of a plurality of legs and a table having each tab fixed to one of the legs.

However, the use of this console in constructing metal tables, particularly those intended to support relatively heavy weights, presents significant problems. '1-that is, French painting patent application 71-
The console described in the '43115 patent does not solve this problem satisfactorily. The stability of this ridge table, and in particular the stability of securing each corner of the shelf to its associated leg, is determined by the fact that the supporting edges of the rectangular valley sides of each console are pressed against the adjacent surfaces of the corresponding leg. determined by the stiffness maintained. This corresponding leg consists, for example, of a metal tube with a square or rounded cross section.

To directly join each support line to the adjacent legs, brazing (for example by arc welding) between the support edge and the legs as described in French Painting Patent Application No. 74-27400.
(soldering) work. However, this relatively expensive and complex brazing operation, especially for parts made of lightweight alloys or stainless steel, has local effects on the surface appearance of these parts, especially for initial primer or finish coatings. There are certain drawbacks that destroy the anti-corrosion protection of. These coatings then have to be redone, which is a pain.

If this soldering is not carried out, the supporting edges of the side pieces of the console are firmly and permanently pressed by the clamping screws associated with the legs. The head of this screw is welded to the side piece forming the bracket of the console and the triangular plate above it, as described in the above-mentioned French Painting Patent Application No. 74-431'15. It is fixed to the auxiliary plate, which is fixed by However, this auxiliary plate is a relatively expensive additional part, and it is extremely disadvantageous in practice to fix this auxiliary plate by welding it to the side pieces of the console and its hexagonal plate. . Furthermore, the long-term support of the supporting edges of the side pieces of the console against the legs can cause local damage to the legs, or even simply to their covering surfaces, affecting the stiffness of the furniture. This can begin to affect furniture with intermittent strain and relatively strong rattling, such as tables on casters that support relatively heavy weights, especially if the legs are made of lightweight metal. I know this from experience.

The object of the invention is to simply eliminate these drawbacks by providing a console as described above which does not have these drawbacks.

A related object of the invention is to provide a method by which such a console (9) can be made easily, in order to ensure the rigidity of the metal furniture containing it.

The console according to the invention has the type described above. The console of the invention extends the valley reinforcing bracket beyond the supporting edge transversely to the plane of the reinforcing bracket by means of a connecting depending portion oriented in the direction of the recess and conforms to the recess transversely to the plate. The shape is such that it can be assembled with corresponding pieces having the shape of one leg. Each interlocking depending portion has at least one hole through which the fastening piece cooperates with a corresponding hole in the leg.

The method of the present invention provides that, within a cutout sheet metal stack having the shape described above and adapted to form a console, each hexagonal side piece is generally rectangular in shape with extending beyond its supporting edge. It is characterized by forming a connected hanging portion. The method of the present invention further includes forming a flange by bending the hexagonal side pieces each having a connecting drooping portion transversely to the plate, and then folding each connecting drooping portion into the connecting drooping portion (10). The shape is determined by providing a flange for the supporting hexagonal side piece by folding it back laterally following the supporting edge of this connecting droop, so that each connecting droop fits into a recess in the top of the console plate. to match the cross section of the adjacent edge of.

Furthermore, according to the invention, a piece of furniture, for example a table with a metal body, is provided with at least one such console for fixing a shelf to the legs of this piece of furniture.

For one example of the present invention, two consoles of the present invention will be described below.
Two interlocking depending portions in the extension of the two triangular side pieces are effectively pressed against the leg on one surface for tightening. Each connecting depending part is connected to this leg by means of a conventional fastening piece, for example, each connecting hole formed for this purpose in each connecting depending part, and two capped holes respectively formed therethrough and corresponding to the legs. It can be easily fixed in a rigid state by means of two screws cooperating with each other. The desired stiffness and durability of the console and of the metal furniture thus assembled does not require expensive additional pieces or complex soldering work that would damage the good appearance of the piece of furniture in question. This way you can definitely get it without having to do it.
