Description

[0001] The invention relates to a drawer side wall for a drawer according to the preamble of claim 1 and to an arrangement comprising at least one such drawer side wall and at least one drawer extension guide.

[0002] Drawer side walls for a drawer, comprising at least one groove extending longitudinally along the drawer side wall for receiving an edge of a drawer base, wherein the groove has at least one upper and one substantially parallel lower retaining rib spaced apart from it, between which the edge of the drawer base can be arranged, are already known from the prior art. These drawer side walls have a welded-on container rail in the lower region, on which the lower retaining rib is arranged.

[0003] A disadvantage of this design is that the drawer side panels are complex and expensive to manufacture due to the welding of the container rail. Furthermore, tolerances result in relatively large deviations in the groove.

[0004] WO 2010036215 A2, DE 9318382 U1, DE 202009005203, EP 3714735 and WO 2022115890 A1 show drawer side walls according to the prior art.

[0005] The object of the present invention is to at least partially eliminate the aforementioned disadvantages and to provide a drawer side wall improved compared to the prior art and an arrangement of at least one such improved drawer side wall and at least one drawer extension guide, which is characterized in particular by simplified manufacturing and / or improved tolerances.

[0006] This problem is solved by the features of claims 1 and 8.

[0007] The drawer side panel is designed so that at least one side surface of the drawer side panel is formed from a single piece of sheet metal, with the groove together with the two retaining ribs being formed into the sheet metal piece by bending.

[0008] This creates the prerequisite for the drawer side panel to be manufactured without an additional container rail, thus simplifying its production. Furthermore, the groove, along with the two retaining ribs, is formed into the sheet metal piece by means of bends; that is, the two retaining ribs are not located on two separate components, but rather within a single component, namely the sheet metal piece. This reduces tolerance-related deviations. The edge of the drawer base can therefore be held more securely in the groove.

[0009] Furthermore, according to the invention, the sheet metal piece forms a hollow profile, preferably with a U-shaped cross-section, into which at least one, preferably at least two, profile bodies, preferably made of plastic, spaced apart from each other in the longitudinal direction of the drawer side wall, are inserted, which stabilizes the hollow profile at least in one direction transverse to the longitudinal direction of the drawer side wall, wherein the at least one profile body has a shape adapted to the inner shape of the hollow profile, and the at least one profile body has the same cross-sectional shape as the sheet metal piece at least in the area of ​​the groove.
