The invention relates to a double-walled drawer side wall having an outer wall and an inner wall, the inner wall being connected to the outer wall. The invention also relates to a method for manufacturing such a double-walled drawer side wall and a drawer having such a double-walled drawer side wall.

Double-walled drawer sidewalls are well known in the art. Most of the side walls of these double-wall drawers are composed of cover-shaped metal plates, in which the outer wall and the inner wall can be integrally formed with each other. However, these two walls can also be connected to each other by known connection techniques. Overall, the advantage of such a double-walled drawer side wall is that the interior can accommodate functional components, for example in the front area, a connection device for detachably connecting with a front wall support, which is pre-installed on The front panel of the drawer. At the rear end, a so-called rear wall support can be provided, on which the rear wall of the drawer can be locked.

The double-walled drawer side wall is usually hood-shaped, wherein the lower side can be placed on the rail system directly or by a container rail connected to the outer wall and/or the inner wall. Such a track system usually includes a main body track fixed on the furniture main body and a movable body relative to the main body track, especially by rolling elements Drawer rail, which can be firmly connected to the drawer during operation. Between these two rails, an intermediate rail can still be arranged to achieve a so-called full pull-out.

The double-wall drawer side wall may have a longitudinally extending shaped container rail in the lower region of the double-wall drawer side wall, and the container rail is firmly connected to the double-wall drawer side wall. This kind of container track usually also contains a narrow piece (Steg) pointing to the inside of the drawer, on which the bottom of the drawer can be placed. The area of the container rail that is vacated during the forming and is substantially U-shaped downward is used to receive and connect to the drawer rail of the rail system. All these details and details can also be preferably provided in the double-walled drawer side wall according to the invention.

Drawers having left and right such double-walled drawer side walls, drawer bottom, rear rear wall and front front panel can usually be detachably hung in a rail system provided in the main body and detachably connected to the rail system. That is, the drawer can be easily inserted into the rail system in the furniture body and removed from the rail system again, for example, for cleaning purposes or during the first installation. The problem is that for the removed drawer, the support (such as the kitchen work board) is damaged due to the operation of the drawer, and is particularly scratched.

The object of the present invention is to provide a double-walled drawer side wall with which the risk of damage is reduced when operating a drawer with such a double-walled drawer side wall. In addition, a method for manufacturing such a drawer side wall and a drawer equipped with the drawer side wall are provided.

According to the present invention, this object is solved by the characteristics of claim items 1, 13, and 15.

The present invention is based on the recognition that the main risk of damage to the support (especially the surface of the kitchen workboard) is that the front side of the drawer placed on the support (especially the surface of the kitchen workboard) is raised because the side walls of the double-walled drawer The lower end of the (usually forming a sharp edge) will scratch and thus damage the support.

Now, the basic idea of the present invention is to make the edge of this critical rear lower end of the outer wall less rounded by the rounded portion, thereby minimizing the risk of damage.

This rounded portion may be formed in the material of the drawer side wall itself, but according to another variation of the invention, the rounded portion may also be formed on a separate edge protection member connected to the outer wall (preferably by locking connection) .

A further improvement of scratch protection can be achieved as follows: the end face of the rounded portion and the remaining double-walled drawer side walls are coated. This coating can be, for example, a powder coating or a lacquer. Other coatings are also considered and possible. Importantly, these coatings are softer and smoother (especially when applied to the end face of the rounded portion) and the risk of scratching is further reduced compared to most metallic materials of the outer wall.
