Definitions

• the present invention relates to a pull-out guide for a drawer, with a guide rail which can be fixed on the furniture body and with a pull-out rail fastened to the drawer, and with an inner profile rail provided with a plurality of ball guides and connecting the guide rail with the pull-out rail, the balls being set and between the two Outer surfaces of the inner profile rail and the inner surfaces of the guide rail and the pull-out rail are arranged such that they can be rolled.
• the pull-out rail attached to the drawer consists of a square tube with rounded corners.
• the guide rail attached to the furniture body is inside the pull-out rail and is solid.
• the balls arranged in sets roll on the inside corners 0 of the pull-out rail. The balls are held over a cage.
• the present invention is based on the object of designing a pull-out guide of the type described at the outset in such a way that it can be produced in a material-saving manner and consequently the weight is reduced. In addition, it should also be cheaper to manufacture.
• the object is achieved in that the guide rail and the pull-out rail are angular in cross-section, the two opposite free edge regions for forming ball guides each running in an inward arc so that three balls form a set of balls.
• the pull-out rail is mounted to the guide rail so that they do not overlap, so that the same number of balls are arranged on one side of the upper region of the inner profile rail as on the same side of the lower range. That is, two balls roll on the upper and lower area on one side and only one ball on the other side.
• FIG. 1 shows the various mounting options, each in a front view.
• the pull-out guide 10 shown in FIG. 1 consists of a pull-out rail 11 fixed to a drawer (not shown), a guide rail 12 fixed to the furniture body (not shown), an inner profile rail 13 as well as balls 14 (not shown in FIG. 1) and a synchronous roller 15. From the figures it follows that the functions of the identical rails can also be interchanged if they are installed accordingly. It can be seen from FIGS. 2 to 4 that the pull-out rail 11 and the guide rail 12 are of an angular design, the corner being rounded to form a ball guide. The outer free edge areas run in inward arcs, so that they also form ball guides.
• the inner profile rail is particularly narrow, as a result of which particularly precise guidance is achieved, which in turn leads to the lateral stability.
• the arches of the pull-out rail 11 and the guide rail 12 facing one another are still at a distance from one another.
• the pull-out rail 11 and the guide rail 12 are mounted reversely to one another, so that two balls roll in the upper area of the inner profile rail 13 on the left side and two balls 14 in the lower area on the right side.
• the pull-out guide 10 can therefore be referred to as asymmetrical with respect to the vertical and the horizontal central axis.
• the overall height is reduced overall, since the inner profile rail 13 has a substantially lower height.
• the cross sections of the pull-out rail 11 and the guide rail 12 are again the same, with an overlap.
• the pull-out rail 11 and the guide rail 12 are mounted in such a way that the inward arches of the two rails are at a short distance from one another on one side. On this side, two balls are supported on the left side in the upper and lower area, while only one ball is supported on the other side. This creates a longitudinal slot, the height of which is slightly smaller than the height of the inner profile rail 13.
• the synchronizing roller 15, which acts as a friction roller, is mounted on a pin 16 attached to the inner profile rail 13.
• each pull-out guide can also be equipped with several synchronous rollers 15.
• the embodiment shown in FIG. 4 is symmetrical with respect to the horizontal center plane.
• the embodiment according to FIG. 2 can also be equipped with synchronous rollers if one of the inwardly directed arches has sharp edges on the outside.
• the designs according to FIGS. 2 and 4 offer the possibility of installing retraction devices in the longitudinal slot instead of synchronous rollers.
