Description

Technical Field

[0001] The present invention relates to a drawer side wall in the form according to the generic concept of claim 1, and an assembly consisting of at least one such drawer side wall and at least one drawer guide for the drawer.

[0002] A drawer side wall for a drawer, having at least one groove extending in the longitudinal direction of the drawer side wall for accommodating the edge of the drawer bottom, the groove having at least one upper retaining web and a lower retaining web spaced apart from the upper retaining web and extending substantially parallel thereto, and a drawer side wall between the upper retaining web and the lower retaining web in which the edge of the drawer bottom can be arranged is already known from the prior art. Such a drawer side wall has, in the lower region, a welded container rail on which the lower retaining web is arranged.

[0003] The disadvantage in this case is that the production of the drawer side wall is time-consuming due to the welding of the container rail, making the drawer side wall expensive. Furthermore, relatively large displacements occur due to manufacturing errors in the grooves.

[0004] WO 2010 / 036215, DE Utility Model No. 9318382, DE Utility Model No. 202009005203, EP 3714735 A1, and WO 2022 / 115890 show drawer side walls according to the prior art.

[0005] The object of the present invention is to at least partially eliminate the above-mentioned disadvantages, and in particular to provide an improved drawer side wall compared to the prior art, which is excellent in terms of simple production and / or improved manufacturing errors, and an assembly consisting of at least one such improved drawer side wall and at least one drawer guide for the drawer.

[0006] This object is solved by the features according to claims 1 and 8.

[0007] That is, on the drawer side wall, at least one side surface of the drawer side wall is formed from an integral metal sheet piece, and it has been specified that the groove, together with both holding webs, is formed by bending in the metal sheet piece.

[0008] This provides the prerequisite for being able to form the drawer side wall without an additional container rail, thereby simplifying the manufacture of the drawer side wall. Furthermore, the groove, together with both holding webs, is formed by bending in the metal sheet piece, that is, both holding webs are not two different components, but are arranged within a single component, that is, within the metal sheet piece. Thereby, misalignment due to manufacturing errors is reduced. The edge of the drawer bottom surface can thus be more reliably held within the groove.

[0009] Furthermore, according to the present invention, the metal sheet piece preferably forms a hollow profile having a U-shaped cross-section, and 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 into the hollow profile. The profile bodies stabilize the hollow profile in at least a direction transverse to the longitudinal direction of the drawer side wall. Preferably in this case, at least one profile body has a shape adapted to the inner shape of the hollow profile, and at least one profile body has been specified to have the same cross-sectional shape as the metal sheet piece, at least in the region of the groove.

[0010] Advantageous embodiments are defined in the dependent claims.

[0011] Further details and advantages of the present invention will be explained in more detail below with reference to the drawings based on the description of the drawings.
