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). <IMAGE> |
