ABSTRACT:
An extension pull-out guide assembly for a drawer includes a supporting rail on the side of the furniture body, a center rail and a pull-out rail on each side of the drawer. The supporting rail has one or two resilient stops of resilient material and a rigid stop which cannot be overrun by a roller of the center rail. A lower horizontal flange of the supporting rail is provided at the outer edge thereof with a vertical flange. An opening is provided in the vertical flange in front of rigid stop. When the center rail is extracted from the supporting rail, the roller is first held by the resilient stop. When the roller is moved past the resilient stop, it comes to rest against the rigid stop. Thus, the center rail cannot be extracted unintentionally from the supporting rail. The roller may, however, be laterally moved through the opening, such that the center rail can be released from the supporting rail.
