Definitions

  • the present invention relates to a device for fixing a drawer on a rail of a pull-out slide, comprising a drawer, a fastening means fixed to a rail and a receiving element held on the drawer which is at least partially overlapped by the fastening means.
  • a pull-out guide for drawers is shown in which a hook is integrally formed or fixed on a rail of the pull-out guide.
  • a spring element can be easily seen on the hook in order to clamp the drawer between the rear hook and a front fastening device. However, this reduces the overlap between the hook and the drawer.
  • a drawer has manufacturing-related tolerances in the longitudinal direction of a rail of the pull-out guide. So that the pull-out guide can be used for different drawers, the length of the mostly hook-shaped fastening means is limited in the longitudinal direction of the drawer, for example so that the fastening means can be inserted into an opening in a rear wall made of a wood material. If such tolerances lead to a lack of overlap between the fastening means and a receiving element on the back of the drawer, the drawer is no longer secured against lifting.
  • EP 1 986523 B1 therefore proposes an adjustable bracket on a rear end of a running rail to set a drawer.
  • the adjustable bracket has a large number of components, so that the assembly and manufacture are complex.
  • the receiving element which is at least partially overlapped by the fastening means, is movably held on the drawer and is pretensioned towards the fastening means.
  • tolerance compensation can take place in the longitudinal direction of the rail, so that sufficient coverage of the fastening means on the receiving element is ensured. This ensures that the drawer is securely fixed to the rail of the pull-out slide.
  • the receiving element is preferably arranged at a distance from a rear wall and a bottom of the drawer and is moved during assembly via the fastening means to the drawer against the force of a spring or the elastic receiving element.
  • the fastening means can rest against the receiving element in a clamping manner, the clamping force being generated either by an additional spring or by the elastically formed receiving element itself.
  • the receiving element is slidably guided on the holder.

  • the receiving element can comprise a sleeve into which the fastening means is at least partially inserted.
  • a sleeve can be slidably mounted on a tubular holder, so that a particularly compact structure results.
