Description

Technical Field

[0001] The invention relates to a side wall for a drawer according to the preamble of claim 1 and a method for producing such a side wall. Background Art

[0002] From the prior art, side walls for drawers are known which comprise a support profile and a holding device for connecting the side wall to a drawer rear wall or a drawer front wall, which are at least partially formed from a metal material and are welded to each other by means of a laser weld.

[0003] However, there is the risk that, under certain loads, for example when adjusting the inclination of the drawer front wall via the rail, the retaining device will again fall off the support profile. Summary of the invention

[0004] The object of the present invention is to provide a side wall which is improved compared to the prior art and a method for producing such an improved side wall, wherein the side wall is characterized in particular by a greater load-bearing capacity without the retaining device falling off the supporting profile.

[0005] This object is achieved by the features of claims 1 and 10 .

[0006] In the side wall, it is provided that the support profile has, in the region of the at least one laser weld seam, at least one laser deformation caused by the laser and separate from the at least one laser weld seam.

[0007] Therefore, additional laser treatment is also performed in the region of the weld. Thus, on the one hand, the guide rail is more stable, and on the other hand, the holding device is not easily torn off.

[0008] In other words, during the welding operation for fastening the retaining device, heat is additionally introduced into the support profile by means of the laser. This causes the at least one support profile to deform slightly and bend upwards. This means that stresses are generated in the support profile in a targeted manner, which result in a preferred deformation.

[0009] Given certain material qualities, structural changes may also occur and thus initiate a hardening process.

[0010] By additional laser treatment, the support profile can be more strongly supported, so that a greater load on the drawer rear wall or drawer front wall connected to the retaining device is possible. This is advantageous, for example, when the inclination adjustment of the drawer front wall is achieved via a railing.

[0011] Similarly, in the method for manufacturing the side wall for a drawer of the present invention, it is provided that: the at least one supporting profile and the at least one retaining device are welded to each other by means of a laser weld, and in the area of ​​the at least one laser weld, a laser deformation portion separated from the at least one laser weld is induced by irradiation with a laser.

[0012] According to a preferred embodiment of the side wall, the majority of the at least one laser weld is arranged at a location of the at least one support profile at which the at least one retaining device and the at least one support profile are in contact. In the method, provision can accordingly be made for the majority of the at least one laser weld to be arranged at a location of the at least one support profile at which the at least one retaining device and the at least one support profile are in contact.

[0013] Alternatively or additionally, it can be provided that the majority of the at least one laser weld is arranged at a location of the at least one support profile at which the at least one holding device and the at least one support profile are not in contact. In other words, the at least one holding device and the at least one support profile are designed to be contactless at this location. In the method, it can be provided accordingly that the majority of the at least one laser deformation is arranged at a location of the at least one support profile at which the at least one holding device and the at least one support profile are not in contact.

[0014] Another advantageous design of the side wall is characterized in that the at least one laser deformation is arranged offset from the at least one laser weld seam on the at least one support profile. In the method, provision can accordingly be made for the at least one laser deformation to be arranged offset from the at least one laser weld seam on the at least one support profile.

[0015] It has proven to be advantageous if the at least one laser deformation and the at least one laser weld have at least one intersection point and / or if the at least one laser deformation extends over a greater width in a direction transverse to the longitudinal direction of the at least one support profile than the at least one laser weld and / or if the at least one laser deformation is at least partially linear and / or has a sawtooth shape. In the method, provision can accordingly be made for the at least one laser deformation and the at least one laser weld to be arranged relative to one another in such a way that the laser deformation and the laser weld have at least one intersection point and / or if the at least one laser deformation extends over a greater width in a direction transverse to the longitudinal direction of the at least one support profile than the at least one laser weld and / or if the at least one laser deformation is at least partially linear and has a sawtooth shape.

[0016] A preferred embodiment of the side wall is characterized in that the at least one laser weld seam and the at least one laser deformation are at least partially linear, and wherein the laser weld seam and the laser deformation have different line widths, preferably wherein the line width of the laser deformation is greater than the line width of the laser weld seam. In the method, provision can accordingly be made that the at least one laser weld seam and the at least one laser deformation are produced using the same laser, wherein after producing the laser weld seam and before producing the at least one laser deformation, the focus of the laser is adjusted, preferably widened.

[0017] And finally, it has proven to be advantageous for the side wall that the at least one retaining device and the at least one supporting profile are partially in contact on a first side of the supporting profile, and wherein the at least one laser weld seam and the at least one laser deformation are arranged on a second side, which is opposite the first side and is separated from the first side by the material thickness of the supporting profile, preferably wherein, in the use position of the side wall, the first side is the top side of the supporting profile pointing upwards, and the second side is the bottom side of the supporting profile pointing downwards. In the method, provision can accordingly be made that the at least one retaining device and the at least one supporting profile are partially in contact on a first side of the supporting profile, and wherein the at least one laser weld seam and the at least one laser deformation are arranged on a second side, which is opposite the first side and is separated from the first side by the material thickness of the supporting profile, preferably wherein, in the use position of the side wall, the first side is the top side of the supporting profile pointing upwards, and the second side is the bottom side of the supporting profile pointing downwards.

[0027] The holding devices 3 and 18 can be arranged partially in a hollow profile 16 which is connected or connectable to the support profile 2 .

[0028] In the following figures, the invention is explained using the example of a holding device 3. As an alternative or in addition, the invention can be applied to a holding device 18.

[0029] Figure 3 and Figure 4 The supporting profile 2 of the side wall 1 with the retaining device 3 is shown in a perspective view from above and in a partial view from below, wherein Figure 3 The section 17 is additionally shown enlarged.

[0030] In the case shown, the support profile 2 can have a horizontal web having a first side surface 11 and a second side surface 12 which is opposite the first side surface and is spaced apart from the first side surface 11 by a material web of the support profile 2 .

The at least one laser weld 4 is mostly arranged at the location of the at least one support profile 2 at which the at least one holding device 3, 18 and the at least one support profile 2 are in contact.

[0035] The support profile 2 has at least one laser-induced laser deformation 5, 6 in the region of the at least one laser weld seam 4, which is separate from the laser weld seam.
