Abstract
An extension pull-out guide assembly for each side of a drawer includes a pull-out rail fastened to the drawer, a supporting rail on each side of a furniture body and a center rail arranged between the pull-out rail and the supporting rail. A runner roller is mounted on the center rail. The supporting rail has stop members for the runner roller of the center rail to limit the extracting movement of the center rail. The stop members hold the runner roller of the center rail in clamping arrangement between a first passable stop member that can be overrun and a second unpassable stop member. Thus, unintentional displacement of the center rail in the extracted position towards the front as well as towards the rear is prevented.
Claims8
An extension pull-out guide assembly for use on each of opposite sides of a drawer to enable the drawer to be slidably insertable into and withdrawable from a cabinet or article of furniture, said assembly comprising:
- a supporting rail to be fixed to the body of the cabinet or article of furniture,
- a pull-out rail to be fixed to the drawer;
- a center rail mounted between said supporting and pull-out rails and slidable relative thereto, said center rail having mounted thereon at least one runner roller rollingly positioned within said supporting rail;
- whereby said pull-out rail is slidable relative to said center rail and said center rail is slidable relative to said supporting and pull-out rails during insertion and withdrawal movements of the drawer relative to the cabinet or article of furniture;
- and
- front stop means on said supporting rail for limiting withdrawal movement of said center rail relative to said supporting rail and for holding said center rail at a maximum pull-out position relative to said supporting rail, said front stop means comprising a first stop member to be abutted by said runner roller to thereby limit normal relative withdrawal movement of said center rail, said first stop member being passable by said runner roller upon further withdrawal movement of said center rail, and a second stop member to be abutted by said runner roller upon said further withdrawal movement and unpassable thereby, whereby said runner roller is clamped between said first and second stop members, thereby preventing unintentional movement of said center rail relative to said supporting rail in either the insertion or withdrawal directions.
