Abstract:
Ein Antrieb weist eine drehbare Welle (10) und mindestends einen Rollenkopf (20) auf, der gegenüber der axial festgehaltenen Welle verschieblich jedoch selbst undrehbar ist. Der Rollenkopf wirkt über windschief bezüglich der Wellenachse angeordneten Rollen (6) mittels Reibung auf die Welle. Bei einer Drehung der Welle wird so eine axiale Verschiebung des Rollenkopfs erzeugt und von diesem auf einen damit verbundenen Schiebeflügel oder dgl. übertragen.
Abstract:
Ein Scharnier, insbesondere für einen Herd, umfaßt ein Gehäuse, an dem ein Schwenkarm (4) schwenkbar (5) gelagert ist. Um ein derartiges Scharnier zu verbessern ist an dem Gehäuse ein Antrieb (8) zum Betätigen des Schwenkarms (4) vorgesehen (Fig. 2).
Abstract:
To provide a movable body driving device which has simple structure and is capable of moving a movable body in a certain direction and automatic drawer equipment. A movable body driving device is provided which comprises a roller 12 as a rotary member which is rotatably supported on an inner frame 11 as a supporting member and a motor 13 for rotating the roller 12. The roller 12 is brought in contact with the movable body, which is adapted to be movable in a certain direction, with predetermined force using elastic force of coil springs 21, 22, 23 as elastic members. The movable body is moved by frictional force between the movable body and the roller 12. Automatic drawer equipment employing the movable body driving device as its drawer driving mechanism is also provided.
Abstract:
An apparatus for moving sliding gates that slide on two or more bottom idler wheels along a guide rail comprises, in combination: mobile movement means, designed to slide fixedly with respect to the gate itself on a slide guide, remaining adherent thereto during the displacement of the gate from the opening position to the closing position and vice versa, as well as electronic means for detecting the position of the gate both when it is moving and when it is stationary and for interrupting the motion of the gate in the case of obstacles present on the opening/closing path of the gate itself.
