Description

[0001] Drawer side panel

[0002] The invention relates to a drawer side wall for a drawer according to the preamble of claim 1. The invention further relates to a drawer with at least two such drawer side walls and to a method for mounting a drawer bottom on such a drawer side wall.

[0003] WO 2017 / 144521 A1 discloses a drawer side wall in which adapters are arranged on the drawer side wall to which a drawer base can be attached.

[0004] The disadvantage is that this solution is not suitable for securely attaching thin drawer bottoms, i.e., drawer bottoms with a thickness of less than 10 mm, to the drawer side panel. Furthermore, the drawer side panel is complex to manufacture, as several adapters must be attached to the drawer side panel and aligned relative to each other.

[0005] The object of the present invention is to at least partially remedy the disadvantages known from the prior art and to provide a drawer side wall that is improved compared to the prior art and is characterized in particular by the fact that thin drawer bottoms can be attached to the drawer side wall in a simple and secure manner. Furthermore, a drawer with at least two drawer side walls improved in this way and a method for mounting a drawer bottom on such an improved drawer side wall are to be provided.

[0006] This object is achieved by the features of claims 1, 14 and 15. In the drawer side wall for a drawer according to the invention, it is provided that the drawer side wall comprises at least one groove-shaped receiving channel running between two essentially parallel webs, into which an edge of a drawer base can be inserted, wherein at least one claw is provided on the at least one receiving channel for preferably clamping the edge of the drawer base. The at least one claw is inclined relative to one of the webs of the receiving channel at an angle 9 between 45° and 85°, preferably between 50° and 80°, particularly preferably between 55° and 75°. For example, the angle can be 60°.

[0007] Contrary to the teaching of WO 2017 / 144521 A1, the at least one claw has a relatively large angle. This size has proven to be ideal for securely fastening thin drawer bottoms. The core of WO 2017 / 144521 A1 is that the claw of the adapter is elastically deflected about an axis parallel to the longitudinal axis of the receiving channel. This effect plays a role in the present invention, but not the only one. A further important effect is that when the edge of the drawer bottom is inserted into the at least one receiving channel, the at least one claw digs or eats into the material of the drawer bottom, at least in sections, whereby a retaining effect counter to the joining direction can be achieved. At the same time, however, the edge of the drawer must not be cut too deeply, which would be the case if the angle of the at least one claw were too large.Otherwise, the edge of the drawer bottom would break, which in turn would impair the drawer bottom's grip in the receiving channel. Furthermore, an excessively large angle of at least one claw would also be disadvantageous, as the force required by a fitter to insert the edge of the drawer bottom would be excessive.

[0008] Based on the teaching of the prior art, it was not obvious for a person skilled in the art to find an angle range suitable for the secure fastening of thin drawer bottoms, especially since this step would first of all require the knowledge that the angle of at least one claw relative to one of the webs of the receiving channel represents a parameter which is crucial for solving the problem.

[0009] As already explained, the present invention is particularly suitable for the secure fastening of thin drawer bottoms. In this context, it is advantageous for the at least one claw to have a plurality of points at its end, wherein a minimum distance between the points and an opposite web of the at least one receiving channel is less than 10 mm, preferably less than 8 mm, particularly preferably less than 6 mm. For example, the minimum distance can be 4 mm.

[0010] Alternatively or additionally, the distance between the two webs of the at least one receiving channel may be less than 10 mm, preferably less than 8 mm, particularly preferably less than 6 mm. For example, the distance may be 5 mm.

[0011] It has been found to be particularly advantageous for the secure fastening of thin drawer bases if the at least one claw has at least three, preferably four or five, points at the end, and / or if the at least one claw has a plurality of, preferably equidistant, points at the end, wherein a distance between two adjacent points is between 2 mm and 5 mm. For example, the distance can be 4 mm, and / or if the at least one claw has a plurality of points at the end, wherein at least one of the points is delimited by two sides which enclose an angle between 80° and 120°, preferably between 90° and 110°, and / or if at least one of the points has the shape of an isosceles triangle. For example, the angle can be 100°.

[0012] Solutions are known from the prior art in which claws are arranged below the at least one receiving channel. After inserting the drawer base, the claws are sunk by bending, e.g., into a groove in the drawer base. This, however, requires a further processing step. The assembly of the drawer base can be simplified compared to the prior art in that at least one

[0013] Claw protrudes into at least one receiving channel.

[0014] It has proven advantageous that a plurality of claws, spaced apart from one another in the longitudinal direction of the receiving channel, are provided on the at least one receiving channel for fastening the edge of the drawer base, preferably wherein the claws are designed essentially identically.

[0015] As already explained, a disadvantage of the teaching of WO 2017 / 144521 is that the drawer side wall disclosed therein is complex to manufacture. To avoid this disadvantage, it can be advantageously provided in the present invention that at least one inner surface of the drawer side wall, preferably an entire outer shell of the drawer side wall, is formed from a single piece of sheet metal and the at least one receiving channel and / or the at least one claw is or are formed integrally into the inner surface, preferably wherein the drawer side wall has an outer surface which is aligned substantially parallel to the inner surface. Further preferred embodiments are defined in the further dependent claims.

[0016] As stated at the outset, protection is also sought for a drawer with at least two drawer side walls according to the invention and a drawer base, wherein edges of the drawer base are inserted into the receiving channels of the at least two drawer side walls, preferably wherein a drawer rear wall is provided which is connected in an articulated manner to the at least one drawer base.

[0017] And finally, protection is sought for a method for mounting a drawer base on a drawer side wall according to the invention, wherein an edge of the drawer base is inserted into the at least one receiving channel in a direction transverse to the longitudinal direction of the receiving channel, wherein the at least one claw digs at least partially into the material of the drawer base, preferably wherein a drawer rear wall is provided which is connected in an articulated manner to the at least one drawer base, and the drawer rear wall is inserted at least partially into at least one rear wall holder arranged on the drawer side wall when the edge of the drawer base is inserted into the at least one groove-shaped receiving channel.

[0018] Further details and advantages of the invention are explained in more detail below with reference to the figures and the drawings.
