Definitions

  • the invention relates to a guide device for guiding a movable relative to a furniture body furniture part, in particular drawer, door or flap, with at least one guide unit, which can be fastened to a furniture carcass rail, a lower rail guide means relative to the carcass rail slidably mounted center rail and an upper Rail guide means relative to the center rail slidably mounted, with an extractable pull-out rail has, and wherein in addition to the lower rail guide means lower rail support means are provided for supporting the center rail on the carcass rail.
  • a guide unit of a guide device or furniture drawer guide which has a carcass rail, a middle rail and a pull-out rail, which are mounted relative to each other via rail guide means relatively displaceable, is also referred to as full extension.
