Definitions

  • the invention relates to a Unterêtauszieh arrangement for pull-out furniture parts, especially drawers and drawers, fastened to the furniture body carcass rail, attachable to the underside of the extendable furniture part pull-out rail and between the carcass rail and the pull-out rail and between these differentially running center rail on both sides of the extendable Furniture part, being provided to allow the mutual displacement of the rails rollers.
  • roller pull-out guides are known in which the rollers are rotatably mounted on the rails by means of axles attached to the rails.
  • roller extension guides usually have relatively large heights and are usually used mainly for to be arranged on the side walls of the pull-out furniture parts pull-out, especially if it is a full extension.
  • Roller full extension with different running medium rail have become known in different embodiments.
  • the CH 679 735 A5 shows a fastened to the side walls of the extendable furniture part differential extract, in which all rollers are arranged on the center rail. In the region of its front end, a front roller is rotatably mounted on the center rail, which projects beyond the center rail downwards.
  • a rear roller In the area of its rear end, a rear roller is rotatably mounted, which projects beyond the middle rail upwards.
  • upper and lower middle rollers are rotatably mounted, of which the lower roller is designed as a play with respect to its axis rotatably mounted differential role.
  • the carcass rail is U-shaped and surrounds the middle rail.
  • the pull-out rail has a horizontal land having a downwardly-directed track for engagement with the front roller and the lower middle track roller of the center rail and an upwardly-directed track for engagement with the upper center track roller of the center rail.
  • the differential extract shown in CH 679 735 A5 has a relatively large height and the differential extension is only slightly stable compared to laterally acting forces.
  • a Unterêtauszieh operation in the form of a full extension with arranged between the rails in cages roller-shaped rolling elements is known from DE 296 16 756 U1.
  • the cages also extend into the areas between the vertical flanges of the adjacent guide rails and have between these vertical flanges rolling about vertical axes rotatable rollers. It is a telescopic extension without differential movement of the middle rail.
  • a guide for extendable furniture parts in the form of a single extension is known from EP 0 196 412 A1.
  • rolling elements are provided, whose axes are aligned perpendicular to each other and which are alternately supported on two opposite of the four running surfaces of the rails.
  • the treads are each offset by 90 ° from each other and have angles of 45 ° to the vertical or horizontal.
  • pull-out guide in the form of a single extension with rolling elements arranged in cages is known from EP 1 066 773 A1. From this document goes u.a. an embodiment (as shown in FIG. 9), in which the pull-out rail has two mutually facing downwardly facing raceways and an upwardly directed track and the carcass rail has two angularly mutually facing upwardly facing tracks and a downward career.
