Description

Technical Field

[0007] , ,

[0001] The invention relates to a drawer guide for drawers, having at least one cabinet rail to be attached to a fixed furniture part and at least one attachment section by means of which the at least one cabinet rail can be attached to the fixed furniture part. The invention further relates to furniture having such a drawer guide and preferably to a method for manufacturing such a drawer guide.

[0002] Drawer guides for drawers are already well known from the prior art. In the prior art, at least one attachment section is usually an integral part of the cabinet rail. That is, the attachment section is formed from an extended part of the cabinet rail. However, this results in high material costs, which also have an adverse effect on the cost of the drawer guide.

[0003] In order to reduce the material costs, it is also known to weld an L-shaped attachment section to the cabinet rail by means of a lap joint. In this case, an overlap is necessary in order to achieve sufficient mechanical stability. For this purpose, the L-shaped attachment section also contributes (more overlap).

[0004] The object of the invention is to provide an improved drawer guide for drawers, furniture having such a drawer guide and preferably a method for manufacturing such a drawer guide with respect to the prior art.

[0005] This object is solved by the features according to claims 1, 15 and 16.

[0006] Thus, according to the invention, it has been determined that at least one attachment section is joined to at least one cabinet rail by butt welding.

[0007] In the context of this application, butt welding is understood to be a welding process that utilizes a butt joint. In other words, two parts are arranged substantially on the same plane, and the end faces of these parts are welded to each other.

[0008] The applicant's experiments have shown, surprisingly, that drawer guides with sufficient mechanical stability can be manufactured even by butt joints between cabinet rails and mounting sections.

[0009] This minimizes material costs. Furthermore, it simplifies the manufacturing process because both the cabinet rails and mounting compartments can be manufactured with simpler shapes.

[0010] The present invention further identifies furniture comprising a fixed furniture portion, preferably a furniture cabinet, a drawer, and at least one such drawer guide, wherein the drawer is supported by the fixed furniture portion so as to be movable via at least one drawer guide.

[0011] The method for manufacturing drawer guides is as follows: - The step of preparing at least one cabinet rail, preferably bending the cabinet rail into a substantially U-shape, - The step of preparing at least one mounting section, - The step of butt welding at least one cabinet rail to at least one mounting section. It has been identified.

[0012] Another advantageous embodiment of the present invention is provided in the dependent claims.

[0013] Preferably, at least one cabinet rail and at least one mounting section may each have at least one end face, and the at least one cabinet rail and at least one mounting section may be connected to each other at their end faces.

[0014] Advantageously, the end face may be specified to be formed by the material thickness of at least one cabinet rail and / or at least one mounting section, preferably having substantially the same material thickness as at least one cabinet rail and at least one mounting section. This can further simplify the manufacture of the drawer guide.

[0015] According to embodiments of the present invention, at least one cabinet rail may be formed in a substantially U-shape. The U-shape provides, on the one hand, good mechanical stability for the cabinet rail, and on the other hand, is an advantageous shape for guiding a drawer rail along the cabinet rail, on which drawers can be subsequently placed.

[0016] It may be specified that at least one end face of at least one cabinet rail is positioned on the leg of a U-shaped cabinet rail.

[0017] Furthermore, it may be specified that at least one mounting section is substantially located on a plane including the legs of the U-shaped cabinet rail.

[0018] These measures can reduce the space required for drawer guides.

[0019] Preferably, at least two mounting sections are provided, and preferably, at least two mounting sections are coupled to at least one cabinet rail at intervals from each other along the longitudinal extension of at least one cabinet rail. This allows for a stable connection between the cabinet rail and the fixed furniture section.

[0020] According to another embodiment of the present invention, at least one mounting section may have a hole pattern for receiving mounting means. By utilizing the pattern, the position of the cabinet rail can be easily adapted to a fixed piece of furniture.

[0021] For mounting, screws can be used, for example. However, basically, all suitable means are available.

[0022] It may be specified that the mounting sections are arranged vertically at the assembly position. This also has a favorable impact on the required space for the drawer guide.

[0023] Preferably, at least one mounting section may also be specified as being joined to at least one cabinet rail via laser beam welding and / or high-frequency welding. This is a simple means of achieving butt welding.

[0024] Preferably, the mounting section may be specified to be substantially formed in the shape of a rectangular parallelepiped.

[0025] Particularly preferably, the length of at least one mounting section may be shorter than the length of the cabinet rail, and preferably the length of the mounting section may be specified to be 1 / 10 to 1 / 5 of the length of the cabinet rail.

[0026] These measures, either individually or in combination, enable the simple and inexpensive manufacturing of mounting sections, and consequently, drawer guides, while saving materials.

[0027] Furthermore, the drawer guide may be specified to have a drawer rail to which it is to be coupled, which is supported so as to be movable relative to the cabinet rail. This allows for a simple implementation of the drawer guide.

[0028] Advantageously, it may also be specified that the drawer guide has an intermediate rail that is movably supported between the cabinet rail and the drawer rail. Thereby, the drawer guide can be realized as being capable of being fully pulled out.

[0029] Regarding the method, it may further be specified that a laser beam welding method and / or a high-frequency welding method are used. This is a simple means of realizing butt welding.

[0030] The further details and advantages of the present invention will be described in more detail below with reference to the drawings based on the description of the drawings.
