Abstract

A guide rail (11) is fixed into the body of the furniture (12) for receiving a runner (15) mounted in one side of the drawer (16). The runner is moved on rollers (17) along a track in a profiled rail (13) at one or both ends of the guide arrangement (10). The area of the profiled rail engaging with the runner has at least one region displaced from the vertical so that it extends in the direction of the lateral forces that occur in the arrangement when the runner is placed under load.

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drawer guide mechanism for furniture or furniture, particularly residential furniture, a guide rail that can be fixed to the furniture main body or furniture main body, a traveling rail that can be attached to the drawer and is guided using rolling elements. And for the type consisting of a shaped rail having a runway at one end section or both end sections for rolling elements.
[0002]
[Prior art]
Various types of drawer guide mechanisms of the above type are known. When the drawer guide mechanism is formed as a partial drawer, the guide rail is integral with the molded rail. Therefore, the traveling rail is attached to the drawer. In such a structure, the drawer is pulled out only partially from the furniture body. In the complete drawer, the drawer guide mechanism includes two traveling rails, one traveling rail is attached to the drawer, and the other traveling rail is attached to the guide rail. A structure in which a stationary traveling rail is formed integrally with a guide rail is also known.
[0003]
In such a structure, the molded rail is provided with a running surface (Laufflaeche) or a running path for rolling elements at both ends. When the drawer starts, the molded rail also runs. In known constructions, the section adjacent to the runway extends in parallel with the side wall of the furniture body to which the guide rail is attached, both in the case of a partial drawer and in the case of a full drawer. That is, usually adjacent sections are positioned vertically. When the drawer runs out, side forces (seitliche Kraft) also act on the guide mechanism. In the known structure, the lateral stability of the guide mechanism is low. Therefore, inconvenience arises especially when the drawer is taken in and out, especially because the section located outside the running path of the molded rail is elastically deformed.
[0004]
[Problems to be solved by the invention]
It is an object of the present invention to improve a drawer guide mechanism of the type described at the outset and to significantly increase the lateral stability of the drawer guide mechanism with a simple structure without increasing the components.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the configuration of the present invention, the section (anschliessender Bereich) following the traveling path of the formed rail is at least partially shifted with respect to the vertical line and acts on the side of the drawer guide mechanism. It is located in the direction of the resultant force or almost in that direction.
[0006]
【The invention's effect】
Contrary to the previously known structure, the section following the runway no longer extends parallel to the side wall of the furniture body to which the guide rail is attached, but extends at least partially inclined. In the drawer guide mechanism formed as a complete drawer, the section is located between the travel paths at both ends and is therefore a middle section (mittlerer Bereich). In the drawer guide mechanism formed as a partial drawer, the section is located between the angle-shaped guide rail and the travel path. The inclination angle with respect to the vertical line is defined according to the structure of the drawer guide mechanism. Based on the appropriate slope of the section, the section is not elastically deformed by the acting lateral force.
[0007]
The section of the molded rail may be variously formed. In one embodiment, the section following the runway of the shaped rail is arranged substantially linearly but inclined with respect to the vertical line. Furthermore, it is also conceivable to fold the section following the traveling path of the molded rail one or more times in the same direction or in opposite directions. In this case, the bent portion may be formed such that the web sections (Steg) located in the same row extend in the direction of the vertical line. Furthermore, the section may be formed in a saegezahnfoermig, arc or similar shape.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The drawer guide mechanism (Schubkastenauszugfuehrung) 10 shown in FIG. 1 and FIG. 2 has a guide rail (Fuehrungsschiene) 11, the guide rail is formed in an angle shape (winkelfoermig), and the side wall 12 of the furniture body (the furniture body) Only the side walls are shown). In the embodiment of FIG. 1, a molded rail (Profilschiene) 13 and a guide rail (Fuehrungsschiene) 11 together form an integral rail.
[0009]
In the embodiment of FIG. 2, an integral rail is formed by a guide rail 11 and a stationary traveling rail (Laufschiene) 14. A traveling rail 15 having substantially the same structure in cross section is attached to a partially-drawn drawer (Schubkasten) 16. In the embodiment of FIG. 1, the traveling rail 14 is omitted. In the embodiment of FIG. 1, the forming rail 13 has three running paths (Laufbahn). In the embodiment of FIG. 2, the molded rail is formed with the same end at both ends (End), and therefore has three running paths at each end. A plurality of rolling elements 17 arranged side by side in the shape of a sphere are provided on each traveling path of the molded rail 13. In particular, as shown in FIG. 2, the sections located between the running paths on the end side of the molded rail extend inclining with respect to the vertical line (Vertikale). This also applies to the embodiment of FIG. An angle formed by a section adjacent to the traveling path or a section located between the traveling paths is defined so that the section extends in a direction of a resultant force of a side force acting on the pulling guide mechanism 10. The section does not extend linearly or arcuately, but may be folded once, preferably multiple times.
[0010]
Further, the molded body may be, for example, a zick-zack-foermige Anordnung, whereby a specific part is shifted with respect to the vertical line depending on the structure of the section, or is positioned obliquely. Yes. In this case, the remaining part may extend in the direction of the vertical line.
[0011]
In the illustrated embodiment, three traveling paths provided corresponding to the traveling rails 14 and 15 are formed by a plurality of times of bending (Abwinkeln). Thereby, a groove (Nut) 18 is formed, and an edge section (Endsteg) 19 is inserted into the groove by bending.
[0012]
The present invention is not limited to the illustrated embodiment. Importantly, the sections adjacent to or between the roads may be formed in various ways, deviating from the vertical line, and as a result, elastic deformation due to lateral force (Seitenkraft) is reduced. That is.
