Definitions

• the present invention relates to a pull-out guide for a pull-out part of a piece of furniture, comprising a guide rail which can be fastened to the body of a piece of furniture, a running rail which can be coupled to a pull-out part and an extension rail arranged between the guide rail and the running rail, which extends in relation to the guide rail and the running rail by means of rolling element cages held rolling elements and synchronized by a cable control.
• Pull-out guides of the generic type are known to sic, the synchronization of the middle rail by a cable control fulfills the purpose, in any possible extension position a maximum overlap between the center rail on the one hand and the guide rail and the running rail on the other. guarantee.
• the cable of the cable control is connected to the front end of the guide rail and the rear end of the center rail.
• the entire length of the rope must be at least twice the length of the Mitteischiene.
• the present invention has for its object to provide a drawer guide of the generic type, which has low cost and has a longer life.
• the cable control consists of a guided around two on the center rail deflection rollers rope which is attached to the WälzConsequently sake mufigen WälzMechlafigen between the running rail and the guide rail on the one hand and the center rail on the other.
• the cable control requires only about half the length of the center rail, which corresponding to the entire cable length the cable control can be reduced by half compared to previously known constructions. This results in a not inconsiderable cost reduction in the production of corresponding pullout guides and beyond there is the advantage that the peripheral speeds of the pulleys over known constructions are also significantly reduced, whereby the expected life of a correspondingly designed pullout guide is considerably increased.
• Multi-part rolling bearings consist of a front and rear roller cage, which are connected by a spacer bar.
• the cable is connected in multi-part rolling bearings on the front lying in the extension direction WälzMechshifigen.
• the cable is preferably connected in the extension direction in the front areas of WälzMechlafige.
• a particularly advantageous embodiment of the invention is that the rope is attached to the WälzSystemurafigen without play.
• the cable is welded to the WälzSystemurafigen, preferably by ultrasonic welding.
• the rope itself does not have to be prefabricated, which results in a further manufacturing advantage.
• Figure 1 is a view of a pullout guide according to the invention
• Figure 2 is a perspective view of the pullout guide according to FIG.
• FIGS. 1 and 2 shows an end view of the pullout guide according to FIGS. 1 and 2
• Figure 4 shows a middle rail of a pull-out guide according to the invention according to an embodiment of the invention as a single part
• Figure 5 is a view of a center rail with WälzMechhimfigen and a
• Figure 6 is a view of a pullout guide from one of Figure 1 opposite viewing direction.
• reference numeral 1 denotes a drawer guide as a whole, which is intended for a pull-out part of a piece of furniture, for example a drawer or the like.
• the pullout guide 1 essentially comprises a guide rail 2, a running rail 3 and a center rail 4 extending the length of the rail.
• the guide rail 2 is fixed in a known manner fixed to the body of a piece of furniture.
• the running rail 3 serves for coupling with a pull-out part of a piece of furniture, for example with a drawer.
• the réellezverofficerernde center rail 4 is disposed between the guide rail 2 and the slide rail 3 and guided against said rails 2 and 3 by rolling elements held in WälzMechshifigen 5, wherein rolling elements are preferably provided as rolling elements, which are not shown further.
• the upper and lower rolling bearings 11 are made of WälzMechhimfigen 5, which are connected together mitteis a spacer rod 10.
• the pullout guide 1 is equipped with a cable control 6 for synchronizing the center rail 4.
• the cable control 6 consists of a guided around two pulleys 7 rope 8, which is fixed to the seen in the extension direction front WälzSystemkarfigen 5.
• the deflection rollers 7 are arranged on the one hand in the front region of the center rail 4 and on the other hand approximately in the middle of the center rail 4 at this, which is particularly the figures 1, 2 and 5 show.
• connection between the WäizSystem hofigen 5 and the rope 8 is executed without play, it is preferred that the cable 8 is welded to correspondingly shaped cable holders 5a. In this case, an ultrasonic welding is preferably used.
• the total length of the required rope 8 corresponds approximately to the entire length of the center rail 4 and is thus practically only half as long as the rope 8 in a prior art construction in which the rope 8 at the guide rail 2 on the one hand and the middle rail 4 on the other end is connected.
• the center rail 4 consists of a formed by a molding process, in cross-section approximately C-shaped profile. In this case, the side webs 4 a of the center rail 4 are folded roof-shaped for the formation of running surfaces 4 b for the rolling elements, which make the figures 3 and 4 very clear.
• the described measures and embodiments of the pullout guide 1 overall result in a cost-effective material-saving production of a corresponding pullout guide 1, combined with the additional advantage of a presumably significantly increased service life due to lower stress, in particular of the pulleys 7 of the pulley control 6.
