Definitions
- the present invention relates to a drawer pull-out guide for movably mounting a drawer on a furniture body, comprising:
- At least one drawer rail to be connected to the drawer, which is mounted so that it can be displaced in a longitudinal direction relative to the cabinet rail, and optionally at least one middle rail arranged between the cabinet rail and the drawer rail,
- At least one of the rails preferably the body rail, the center rail and/or the at least one drawer rail, has at least one profile formed from at least one flat sheet metal with two longitudinal edges running parallel to one another in a cross section normal to the longitudinal direction.
- the invention relates to a drawer side wall with a drawer extension guide of the type to be described and with a hollow chamber profile which is connected or can be connected to the at least one drawer rail of the drawer extension guide.
- the rails of a drawer pull-out guide are often made from a flat sheet metal, which is processed into a profile rail by subsequent bending and/or forming.
- the loads on the drawer slide in the horizontal and vertical directions are absorbed by the finished profiles, as a result of which the drawer connected to the drawer slide can be guided in a stable manner.
- a general problem is the need for metal, which is necessary for the manufacture of a drawer slide.
- a high use of material leads to a high weight and increased costs in serial production. It is therefore desirable to use as little metal as possible, especially since using raw materials in a way that conserves resources has both ecological and economic advantages.
- a drawer extension guide is shown in EP 0363583 A1, with a center rail being movably mounted between the body rail and the extension rail. In a cross-section, the center rail has two lateral catwalks for running rollers. The side catwalks of the middle rail are each made of a cover with double the material thickness. The disadvantage of this is that the bending process for producing the center rail is relatively complex.
- the object of the present invention is to specify a drawer slide of the type mentioned at the outset while avoiding the disadvantages mentioned above.
- the profile of the at least one rail has at least one fold with at least twice the material thickness on at least one longitudinal edge, preferably on both longitudinal edges.
- the profile of the body rail and/or the profile of the drawer rail and/or the profile of the center rail has a fold-over with at least twice the wall thickness on at least one longitudinal edge, preferably on both longitudinal edges.
- this enables a simple bending process for the sheet metal, and on the other hand, the rigidity of the profile in the area of the fold can be increased.
- the fold creates a rounded edge, which reduces the risk of injury from an otherwise sharp longitudinal edge.
- a particular advantage of the invention is that thinner sheet metal than usual can be used to produce the drawer pull-out guide (ie, for example, sheet metal with a thickness of 0.7 mm instead of sheet metal with a thickness of 1.5 mm).
- the rigidity of the highly stressed areas of the cabinet rail and/or the drawer rail and/or the middle rail can be increased by the at least one flap increase.
- the highly stressed areas include, in particular, the running tracks of the body rail and/or the drawer rail and/or the center rail, on which rolling bodies (in particular rolling bodies of a carriage) can roll.
- the highly stressed areas are 1.4 mm thick due to the fold.
- the rolling elements can be optimally guided along the rails thanks to the resistant raceways.
- the remaining areas of the rails, which are not exposed to major loads, can be made with a simple, reduced material thickness (i.e. with a thickness of 0.7 mm).
- the drawer pull-out guide has at least one rolling body, which can be moved at least in sections in the longitudinal direction along the at least one cover.
- At least one between the body rail and the at least one drawer rail arranged carriage is provided, in which at least one rolling body is arranged, and / or
- At least one rolling element mounted rotatably about an axis of rotation is provided, the axis of rotation of the rolling element being aligned transversely to a longitudinal edge.
