Definitions

  • the present invention relates to a guide device for a pull-out device, for example for a corner cupboard. Corner cabinet slides are used to provide better access to the storage space located in the corner of a corner cabinet.
  • the guide device is designed as a multi-part guide rail. According to the example described in this document, three guide rails lying one above the other are provided, between which balls are arranged, so that the individual guide rails can slide relative to the respectively adjacent guide rails.
  • Such guide rails are used for pull-out devices for drawers and the like. It has turned out to be a disadvantage of this solution that the torsional rigidity and the flexural rigidity of such guide rails is limited. In particular, when heavy objects are stored in drawers, the guide rails can become deformed in such a way that the user notices these deformations and interprets them as a qualitative defect. Similar solutions are also in the document DE 3834688 A1 or in the document DE 10 2014 119 729 A1 disclosed.
  • the object of the invention is achieved by a guide device according to claim 1.
  • Advantageous exemplary embodiments of the guide device are the subject matter of claims 2 to 14.
  • a guide device comprises a first guide rail arrangement, a second guide rail arrangement and a third guide rail arrangement, the first guide rail arrangement being intended for stationary installation on or on a base element.
  • the first guide rail assembly includes a first pair of guide rails.
  • the second guide rail assembly includes a second pair of guide rails.
  • the third guide rail assembly includes a third pair of guide rails.
  • the second guide rail arrangement can be displaced relative to the first guide rail arrangement by means of at least two pairs of rolling elements that can each be rolled on a guide rail.
  • the third guide rail arrangement is displaceable relative to the second guide rail arrangement by means of at least one pair of rolling elements.
  • the first guide rail arrangement comprises a toothed rack and the third guide rail arrangement comprises a further toothed rack, the toothed rack and the further toothed rack being in engagement with one another via a toothed belt rotatably mounted on two rollers on the second guide rail arrangement.
  • the first guide rail arrangement can each have a rolling element which is rotatably mounted on the first pair of guide rails and is designed to guide one of the guide rails of the second pair.
  • the guide rail has a top surface, a base surface and a web connecting the top surface and base surface. This arrangement has the advantage that adjacent guide rails can be nested in one another to save space.
  • the rolling element is rotatably mounted on the inside of the web of the associated guide rail, and it can be connected to the guide rail or to a connecting element connecting the guide rail.
  • the rollers of the belt drive are rotatably mounted on the second guide rail arrangement.
  • the guide device comprises a first guide rail arrangement, a second guide rail arrangement, and a third guide rail arrangement, the first guide rail arrangement being intended for stationary installation on or on a base element.
  • the first guide rail assembly includes a first pair of guide rails
  • the second guide rail assembly includes a second pair of guide rails
  • the third guide rail assembly includes a third pair of guide rails.
  • the second guide rail arrangement can be displaced relative to the first guide rail arrangement by means of at least two pairs of rolling elements that can each be rolled on one of the guide rails.
  • the third guide rail arrangement is displaceable relative to the second guide rail arrangement by means of at least one pair of rolling elements.
  • the first guide rail arrangement comprises a first toothed rack
  • the second guide rail arrangement comprises a second toothed rack
  • the third guide rail arrangement comprises a third toothed rack.
  • the first toothed rack and the third toothed rack are in engagement with one another via a toothed belt rotatably mounted on two rollers on the second guide rail arrangement.
  • a fourth guide rail arrangement is provided, which has a fourth toothed rack, the fourth toothed rack and the second toothed rack being in engagement with one another via a toothed belt rotatably mounted on two rollers on the third guide rail arrangement.
  • the rollers of the belt drive are rotatably mounted on the third guide rail arrangement.
  • the toothed racks contain guide elements for guiding in the pull-out direction.
  • the guide elements can be designed in particular as grooves, projections, rail elements, ribs, grooves.
  • the guide rails can be connected by means of a connecting element.
  • the rolling elements can each be rotatably mounted in a leg of the connecting element.
  • the guide rails of the second or third guide rail arrangement can be connected by means of a connecting element which is arranged at a rear end of the guide rails.
  • a guide device can be used as a pull-out device for drawers.
  • a guide device can be used for a corner cupboard.
  • An advantage of the guiding device according to the invention lies in its improved accessibility, i.e. the user has improved access to the contents of the storage compartment or compartments.
  • increased rigidity of the pull-out device can be obtained, which leads to increased dimensional stability of the storage compartment or compartments, so that it is ensured that the storage areas remain essentially horizontal, even when relatively heavy objects are placed on the storage areas are, for example, containers filled with liquids such as beverage bottles or the like.
