    • PCT No. PCT/AT92/00017 Sec. 371 Date Oct. 8, 1992 Sec. 102(e) Date Oct. 8, 1992 PCT Filed Feb. 11, 1992 PCT Pub. No. WO92/13473 PCT Pub. Date Aug. 20, 1992.An extension guide assembly for use on a side of a drawer to guide movement of the drawer into and out of a furniture body includes a support rail to be attached to the furniture body, an extension rail to be attached to the drawer, and a central rail between the extension rail and the support rail. The central rail has a U-shaped transverse profile opening downwardly, and carriages are positioned within the profile of the central rail and support rolling bodies transferring the load of the drawer from the central rail to the support rail. Guide members or runners are disposed on top of the central rail between the central rail and the extension rail. The extension rail has a downwardly open U-shaped transverse cross section including an upper horizontal leg above the guide members, lateral vertical legs extending downwardly from opposite sides of the upper horizontal leg along respective sides of the guide members, and a lower horizontal leg extending from one of the vertical legs to a position beneath each guide member. Thereby the extension rail and drawer are prevented from being lifted from the guide members and the central rail.

    • A drawer slide having a pull-out rail (2) fastened to the drawer, a supporting rail (3) fastened to the furniture carcase, and a centre rail (5) running between these two rails, on each side of the drawer. Load-transmitting rolling bodies are provided. Mounted on the centre rail (5) is a blocking device which locks the centre rail (5) in the rear region of the pull-out path of the drawer in relation to the pull-out rail (2) and in the front region of the pull-out path in relation to the supporting rail (3). The blocking device is formed by a crank (14) rotatably mounted at the rear end of the centre rail (5). The crank (14) has two crank arms (24), each with a projection (25), one of which reaches, when the drawer is extended, into a guideway (18), designed as a control cam, of the supporting rail (3) and the other of which projects, when the rear end of the pull-out rail (2) is located at the crank (14), into a guideway (13), likewise designed as a control cam, on the pull-out rail (2). The centre rail (5) is thus coupled in the front pull-out region to the supporting rail (3) and in the rear pull-out region to the pull-out rail (2).
