Definitions

  • the invention relates to a pull-out with a fastened to a furniture body carcass, attachable to a pull-out furniture part pull-out rail and arranged between the carcass rail and the pull-out middle rail, the rails are mutually slidably guided and at least the pull-out relative to the center rail by means of at least one of the rails rotatably mounted rollers is guided displaceably.
  • rollers serving for displacement of the rails are rotatably mounted on the rails about (at least substantially) stationary to these axes lying.
  • roller pull-out guides are known.
  • load-transmitting rollers are rotatably mounted on all rails and it will be extended without further action, the pull-out and the center rail successively from the carcass rail. It comes at the end of Ausziehweges pull-out of the middle rail to a stop of the pull-out on the center rail and an associated shock, whereby the running culture is impaired.
  • roller extension guides according to the differential type are known, in which a rotatably mounted on the center rail load-transmitting differential roller is present, whereby a synchronous or Differentialiallauf the rails is achieved.
  • the middle rail only covers half the path of the pull-out rail with respect to the carcass rail.
  • pull-out guides which are also referred to as differential roller pull-out guides or shorter differential pull-out guides and have a high running culture, advantageously all the rollers can be rotatably mounted on the middle rail.
  • Such role differential extension guides are for example in the AT 391 603 B . AT 505 053 B1 and EP 2 074 909 B1 described.
  • pull-out guides with a differential run of the rails may be the case that the pull-out rail when inserting the pull-out guide is behind its intended position. This has the consequence that the center rail reaches its fully inserted position in front of the pull-out rail.
  • the fully retracted position of the pull-out rail in the case of a roller pull-out guide with a differential running of the rails causing differential or drive roller must be a sliding shift relative to the surface of the differential guide the rail-causing role. It is characterized a greatly increased effort required, which also depends on the weight of the pull-out furniture part and its loading. In the case of the embodiment of the pull-out guide with a damped pull-in mechanism, such an increased force expenditure can not usually be applied by the pull-in mechanism, so that the pull-out rail is not completely retracted by the pull-in mechanism.
  • pullout guides In addition to roller pull-out guides, in which the rollers are rotatably mounted on the rails, pullout guides are also known, which have equipped with balls or rollers carriage. These have in each case their own advantages and disadvantages compared to roller pull-out guides, whereby the problems resulting from the design and construction differ considerably from those of the roller pull-out guides.
  • Pull-out guides which have trolleys equipped with balls or rollers, have less good running properties than roller pull-out guides.
  • the pull-out rail is not designed detachable from the middle rail without tools. In contrast, this is generally the case with roller pull-out guides.
  • the assembly of Ausziehschienen can be done on both sides of the extendable furniture part with removed slide rails. Additional adapter rails on the pull-out furniture part to connect this with the pull-out rails, so are not required.
  • the DE 20 2008 013 242 U1 shows a further pull-out with arranged between the rails carriage, which have rack profiles.
  • the axes of the meshing with the rack profiles gears are hereby elastically mounted relative to the center rail.
  • Another generic pull-out is from the AT7723U known.
  • the object of the invention is to provide an advantageous pull-out of the aforementioned type with a high running culture. According to the invention, this is achieved by a pull-out guide with the features of claim 1.
  • the carcass rail has a first rack profile and the pull-out rail has a second rack profile.
  • a gear unit having at least one gear is arranged, which is in meshing with the first rack profile and the second rack profile for positively controlling a synchronous running of the rails when pulling the pull-out in a pull-out direction and insertion of the pull-out rail.
  • the adjustment of the basic position in the release position can hereby advantageously by exercising a sufficiently high, acting parallel to the withdrawal force be achieved between the middle rail and the rail, which has the at least partially elastically deflectable rack profile.
  • a sufficiently high, acting parallel to the withdrawal force be achieved between the middle rail and the rail, which has the at least partially elastically deflectable rack profile.
  • Such a force results in a force component acting in the sense of pushing the teeth apart.
  • the teeth of the gear unit and of the at least partially elastically deflectable rack profile are disengaged, if this rack profile is elastically deflectable in the region in which the toothed engagement with the gear unit is present.
  • the pull-out of the center rail in particular without tools, can be removed, for example, for mounting on the pull-out furniture part, and can be used in a montage friendly way back to the center rail.
  • the tooth engagement between the gear unit and the at least partially elastically deflectable rack profile in the elastically deflectable region of this rack profile is present when the center rail is in its fully inserted into the carcass rail position.
  • the removed pull-out can thus be used in this fully inserted position of the center rail in the middle rail and inserted until it is also in its fully retracted position, the positive control between the rails by the elastic deflectability of at least a portion of the racks can be overcome ,
  • the removability of the pull-out rail from the center rail can be realized in a manner usual for roller pull-out guides, in particular by means of an adjustable safety-release part.
  • the safety catch part When the safety catch part is in its open position, one can, with respect to the pull-out direction, be raised front end of the pull-out, so that stop elements of the pull-out rail and the center rail can be moved past each other.
  • the lifting of the front end of the pull-out rail is blocked at least to the extent that the stop elements of the pull-out rail and the middle rail can not be moved past each other and the extraction of the pull-out rail from the center rail is limited by these cooperating stop elements.
  • the center rail relative to the carcass rail is guided displaceably by means of at least one of the rails rotatably mounted rollers. It is then a pure roller pull-out, in which the sliding guide both the center rail relative to the carcass rail and the pull-out relative to the center rail by rotatably mounted about rollers and not arranged by means of between the rails and with respect to these movable carriage , which are equipped with rolling elements.

  • the differential roller supports the synchronous movement of the rails, which supports the positive control caused by the gear unit and rack profiles. It can thereby be achieved particularly advantageous running characteristics of the pull-out, whereby the positive mutual control of the correct mutual position of the rails can be ensured during normal operation. Nevertheless, the pull-out rail, especially for assembly and maintenance purposes, removed and reused in a practical way.
