Description

The present invention relates to a drawer guide for a drawer, comprising at least one cabinet rail to be attached to a fixed piece of furniture, and at least one mounting section to which the at least one cabinet rail can be attached to the fixed piece of furniture. The present invention further relates to furniture equipped with such a drawer guide, and preferably to a method for manufacturing such a drawer guide. Drawer guides for drawers are already well known through prior art. In the prior art, at least one mounting section is usually an integral part of the cabinet rail. That is, the mounting section is formed from an extended portion of the cabinet rail. However, this results in high material costs, which unfavorably impact the cost of the drawer guide. To reduce material costs, it is also known that L-shaped mounting sections are typically welded to the cabinet rails using lap joints. In this case, overlap is necessary to achieve sufficient mechanical stability. The L-shaped mounting section also contributes to this (more overlap). The object of the present invention is to provide a drawer guide for a drawer, furniture equipped with such a drawer guide, and preferably a method for manufacturing such a drawer guide, which is an improvement over the prior art. This problem is solved by the features described in claims 1, 15, and 16. Therefore, according to the present invention, it is specified that at least one mounting section is joined to at least one cabinet rail by butt welding. 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 their end faces are welded to each other. The applicant's experiments have surprisingly demonstrated that drawer guides with sufficient mechanical stability can be manufactured even by butt joints between cabinet rails and mounting sections. This minimizes material costs. Furthermore, it simplifies the manufacturing process because both the cabinet rails and mounting compartments can be manufactured with simpler shapes. According to the present invention, the furniture is further specified as comprising a fixed furniture portion, preferably a furniture cabinet, a drawer, and at least one such drawer guide, wherein the drawer is supported movably by the fixed furniture portion via at least one drawer guide. 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 steps of preparing at least one mounting section and butt welding at least one cabinet rail to at least one mounting section are specified. Another advantageous embodiment of the present invention is provided in the dependent claims. 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. Advantageously, the end face may 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 further simplifies the manufacture of the drawer guide. According to embodiments of the present invention, at least one cabinet rail may be substantially U-shaped. The U-shape provides, on the one hand, good mechanical stability for the cabinet rail, and on the other hand, an advantageous shape for guiding a drawer rail along the cabinet rail, on which drawers can be subsequently placed. 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. 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. These measures can reduce the space required for drawer guides. 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 portion. According to another embodiment of the present invention, at least one mounting section may have a hole pattern for receiving mounting means. By utilizing this pattern, the position of the cabinet rail can be easily adapted to the fixed furniture portion. For mounting, screws can be used, for example. However, basically, all suitable means are available. The mounting sections may be specified to be arranged vertically at the assembly location. This also has a favorable impact on the required space for the drawer guide. Preferably, at least one mounting section may also be specified as being joined
