Description
11.~,~7~9'~
The invention relates to a drawer side wall of metal, in particular of aluminium, comprising a vertical flange forming the lateral limitation o~ the drawer, a lower fastenin~
flange for the drawer boktom and an upper horizontal-runniny flange for a supporting roller mounted on khe body of the piece of furniture.
The invention further relates to a proces~ for manufacturing a drawer of this kind, the side wall profile being injection moulded or extruded with a continuously straight horizontal running flange of aluminium or the like.
Many drawers are injection moulded, either as an integral piece of plastics material or assembled of individual structural members, i.e. the two drawer side walls, a front panel, a rear wall and a bottom.
In conventional drawers, the drawer side walls are provided with pull-out rails of a pull-out guide assembly which facilitates insertion and extraction of the drawer into or out of the body of a piece of furniture.

~,' '`'~' J.3~799~
Lately, there has been an increasing use of drawer side walls of metal, the running flange for the pull-out guide assembly being directly moulded to these drawer side walls. Drawers of this kind are advantageously of die cast or extruded aluminum.
It is also advantageous to provide the pull out rails of a pull-out guide assembly, which are on the side of the drawer, with a so-called run-in means. This means that at the front end of the rail, the horizontal running flange extends towards the front end of the drawer rail obliquely upwards.
When the roller on the side of the body comes to lie in this region, the drawer is by its own weight automatically pressed backwards over the slope of the running flange and pulled into the body of the piece. Even a drawer which has not been carefully closed will therefore not project from the body of ~he piece of furniture.
In one aspect the invention provides a drawer side wall for incorporation into a drawer to be mounted for sliding movement into and out of the body of an article of furniture, said drawer side wall having upper and lowsr sides and forward and rearward ends and comprising: a vertical flange to define a lateral limit of the drawer; a lower ~astening flange extending laterally from a lowsr portion o~ said vertical flange and to be used for attaching said drawer side wall to a bottom of the drawer; an upper horizontal running flange extending laterally from an upper portion of said vertical flange and to run on a support roller to be mounted on the body of the article of furniture; said vertical flange, said lower fastening flange and said upper running flange comprising an integral and unitary metal structure resulting from the injection molding or extrusion of said metal; said vertical flange having formed therein, adjacent a .

forward end thereof, a recess; said upper running flange having a forward portion inclined upwardly toward a forward end thereof; and said upwardly inclined forward portion of said upper running flange resulting from upward deformation of the metal of said vertical flange above said recess upon the formation of said recess by mechanical deformation into said vertical flange.
In preferred embodiments of this aspect, the invention provides:
The above drawer side wall, further comprising an additional flange extending laterally from said vertical flange at a position spaced below said upper running flange, said upper running flange, said additional flange and an upper portion of said vertical flange thus defining a running groove for the support roller, and said recess being in said upper portion of said vertical flange.
The above drawer side wall, wherein said recess defines a rectangular surface when viewed from the side of said drawer side wall; and further comprising indicia on said rectangular surface.
The above drawer side wali, wherein said recess is wedge-shaped as viewed in horizontal section through said vertical flange, said recess having a greatest depth at a front end thereof; and wherein said depth of said front end of said recess is greater than half the thickness of said vertical flange.
The above drawer side wall, wherein said vertical 1ange has a thickened portion at a location above said recess, and wherein said metal comprises aluminum.

The above process, comprising forming said recess to be wedge-shaped as viewed in horizontal section through said vertical flange, with said recess having a greatest depth at a front end thereof, and comprising forming said recess such that said depth thereof at said front end thereof is greater than half the thickness of said vertical flange.
The above process, comprising forming said metal structure with said vertical flange having a thickened portion above said recess.
In the following an embodiment of the invention will be described in more detail with reference to the figures of the drawing in which Figure 1 shows a side view of a drawer according to the invention, Figure 2 shows a top view of the front Eegion of the drawer according to the invention, Figure 3 shows a front view of the drawer according to the invention, ~3:~l99~
and Figure 4 shows a sectional view along line I-I o~ Fig. 1 In the drawings, the other parts o the drawer, namely the front panel, the rear wall and the bottom, are not shown, because these parts and their connection with the drawer side wall are state of the art and not subject of the invention.
As already mentioned, the drawer side wall is preferably an extruded aluminium profile. It may, however, also be a different metal suited for the same kind of processing~
The drawer side wall comprises a vertical ~lange 1 forming the lateral limitation of the drawer, the upper horizontal running flange 2 on which a roller (not shown), which is lS mounted on the side of the cabinet body, runs, and a lower horizontal fastening flange 3 for fasteninc~ the drawer bottom.

The upper horizontal flange 7 of the box profile 4 and the running flange 2 define the running groove 8 in which the roller mounted on the side of the cabinet body runs~
The running flange 2 is further provided with lateral limiting flanges 9 which abut on both sides of the roller and thus improve the lateral stability of the drawer in the drawer guiding.
Moreover, the running flange 2 is in a manner known per se provided with stop members 10 which limit the running path of the drawer.
As can be seen from the figures of the drawing, the drawer side wall is cl0s2 to the front edge 11 provided with a deformation 12. Said deformation 12 defines, as can be seen in Fig. 1, a rectangular surface, when the side wall is viewed from the side.
~y means of the deformation 12, the region 6 of the vertical flange 1 is extended in the direction of double arrow A. An insertion slope 13 is thus formed at the running flange 2.
As can particularly be seen from Fig. 4, the deformation 12 in the vertical flange 1 is wedge-sr,aped and ends 7 13~7~
obliquely towards the rear, its maximum depth being at the front end 14.
At the front end 14, the breadth bV of the recess is greater than the breadth bS of the vertical flange 1.
The vertical flange 1 is above the deformation 12 provided with a thickening 15 which forms the transition to the running flange 2.
As already mentioned, the bottom of the deformation 12 may be provided with a logo 16 or the like.
