Problems solved by technology

However, under heavy loads, the tilting torque can lead to a bending of the guide rail profile due to the forces transmitted axially via the rolling elements, thus limiting the load-bearing capacity of the pull-out guide

Embodiment Construction

[0027] Two exemplary embodiments of the pull-out guide are described in more detail in the figures described below. figure 1 to 8 relate to the first exemplary embodiment, Figure 9 A second exemplary embodiment is shown, which is modified with respect to the first. In all figures, the same reference symbols designate the same or identically acting components.

[0028] figure 1 A side view of the first exemplary embodiment of the pull-out guide is schematically shown in a partially extended position. The pull-out guide has three guide rails: a main rail 10 , a middle rail 20 , and a slide rail 30 .

[0029] The middle rail 20 is guided such that it is in each case by means of roller-shaped rolling elements ( figure 1 Not shown in ) is displaceable relative to the main body rail 10 and relative to the slide rail 30. The rolling elements used are preferably held in a rolling element cage. Each pair of rails (main rail 10 / middle rail 20 or middle rail 20 / sliding rail 30) ca...

Abstract

The invention relates to a pull-out guide for movable furniture parts, in particular drawers, having a basic-structure rail (10), a C-shaped centre rail (20) and a running rail (30), which can be fastened on the furniture part, wherein the C-shaped centre rail (20) has inwardly oriented inner rolling-body tracks (21', 22') for roller-form rolling bodies (41, 43, 44, 46, 47), which are arranged between the centre rail (20) and the basic-structure rail (10), and also has at least two outwardly oriented and outwardly inclined outer rolling-body tracks (22''), which are spaced apart from one another by a horizontal portion (21) of the centre rail (20) and are intended for further roller-form rolling bodies (51, 52, 53, 54), which are arranged between the centre rail (20) and the running rail (30). The pull-out guide is distinguished in that the C-shaped centre rail (20) has formed on it a free limb (26) which engages partially around the basic-structure rail (10), wherein a further inner rolling-body track (26') for roller-form rolling bodies (42), which are arranged between the centre rail (20) and the basic-structure rail (10), is formed on the inner side of the limb (26).

Description

technical field [0001] The invention relates to a pull-out guide for movable furniture parts, in particular drawers. The pull-out guide has a main body rail, a C-shaped middle rail and a slide rail fixable to the furniture part, wherein the C-shaped middle rail has a roller-shaped center rail for being arranged between the middle rail and the main body rail. an inwardly facing rolling element track for the rolling elements, and at least two outwardly facing and inclined outer rolling element tracks spaced from each other by a horizontal section of the middle rail for further rollers arranged between said middle rail and the slide rail For shaped rolling elements. Background technique [0002] This pull-out guide has a main rail, a central rail and a slide rail, i.e. three rails that are movable relative to each other, so that movable furniture parts, such as in particular drawers also called compartments, or device brackets, etc. Extends smoothly and extends fully out of t...
