Abstract:
A power drive mechanism (10) for a motor vehicle liftgate includes a linking arm (18) pivotally connected with the liftgate, a crank arm (12) drivable for pivotal movement and connected with the linking arm (18), and a gear train (20) operatively engaging the crank arm (12). A drive motor (34) is operatively connected with the crank arm (12) through the gear train (20) to provide power assisted opening and closing of the liftgate. The gear train (20) is disengageable from the drive motor (34) to permit manual opening and closing of the liftgate without backdriving the drive motor (34). An actuator (74) is operatively connected with the gear train (20) to move the gear train into and out of engagement with the drive motor. A holding linkage (60, 62) is operatively associated with the gear train (20) to maintain the gear train (20) in engagement during power assisted opening and closing of the liftgate.
Abstract:
The invention relates to an emergency opening device for a preferably automatic two-panel sliding door having an energy storage element embodied by a rubber belt (6). Said rubber belt (6) is on one side irremovably fixed in a support (9) and on the other side removably fixed to a holding device (7) by means of a slide (8). During normal operation of the sliding door the pretensed rubber belt (6) has no effect. The holding device (7) releases the slide (8) with the rubber belt only in an emergency, such as a fire or power failure. The slide (8) interacts with the pulley carriages (5b) of the sliding door and by means of the energy stored in the rubber belt (6) moves the sliding panels (1a, 1b) into the fully opened position. To prevent a sudden, severe impact of the slide (8) against the pulley carriage (5b) the slide (8) comprises a friction brake (82, 83, 84). This brake (82, 83, 84) is released by a control device (56) only after the slide has contacted the pulley carriage (5b) so that the entire energy stored in the rubber belt (6) is then able to act upon the pulley carriage (5b). When the emergency is over the rubber belt (6) is tensed during the first closure of the sliding door by the movement of the pulley carriage (5b) and again fixed to the holding device (7).
Abstract:
A portable remotely controlled automatic door closing apparatus enables the door of a room or office to be closed from a remote location within the room or office by transmitting a signal to an actuator (48) which exerts a force on the door to move it from an opened position to a closed position. The apparatus comprises a battery or AC powered motor (36) which moves a lever arm into engagement with the door to rotate the door abolut its hinges from the open to the closed position. The apparatus is free standing and immobilized on the floor in a non-connected relationship thereto between an adjacent wall and the door in its open position. The apparatus is immobilized to prevent slipping by a floor engaging mechanism, such as an adhesive (134), an anti-skid rubber material, or suctioncups, or carpet engaging projections.
Abstract:
The invention relates to an emergency opening device for a folding hinged door (1) or a folding hinged gate using an electric motor drive mechanism with an electromagnetic engaging and disengaging clutch to open and close the wings (2, 2', 3, 3'). The invention is characterized in that an emergency opening device, which is assigned to the door, comprises an elastic traction or pressure mechanism (12, 15, 19, 22) which can be prestressed when closing the door and which engages in the driving axle (6, 6') of the outer wing (2, 2') or in the region of the main closing edge (7, 7') of the inner wing (3, 3').
Abstract:
The openable window sash is in the closed position secured to the frame by locking means on the sash engaging lock fittings on the frame. After release of the locking means from the lock fittings my means of an operating device the sash is moved to an open position by at least one window operator (14, 15) positioned at a frame member. The sash is moved to a ventilating position by the operating device which has a motor (3) which via a driving member (4) moves a locking rod (7) which is longitudinally displaceable in a sash member (2), said locking rod being also in engagement with a relative to the longitudinal frame member inclined section (10) of a track (9) in the lock fitting (8) of the frame. By longitudinal displacement of the locking rod the sash is moved in a direction away from the frame, the sash being, until the ventilating position has been reached, secured to the frame by the engagement between the locking rod and the track of the lock fitting.
Abstract:
An automotive door system includes a hinge supporting a door. A door check module interconnects to one of the vehicle and the door by a linkage assembly. An output shaft is connected to the linkage assembly and rotates relative to a door check module housing. The output shaft provides an output torque to check the door in a desired door position. A sensor detects rotation of the shaft and produces a signal in response thereto. A brake assembly includes a shaft member operatively connected to the output shaft. The brake assembly has a normally closed position in which the shaft member is grounded to the housing in a door check mode. The brake assembly includes an open position that corresponds to one of a door closing mode and a door opening mode. The brake assembly moves from the normally closed position to the open position in response to the signal.
Abstract:
The invention relates to a device for opening the cabinet door of a cabinet body, wherein the cabinet door (11) is attached to the cabinet body (10) by means of self-closing hinges (12), wherein the cabinet door (11) is held in the closed position at a small distance (x) from the front side of the cabinet body (10). In order to allow the cabinet door to be opened without gripping elements, without hindering the self-closing of the hinges, the invention provides for a unit (20) having an ejection piston (21) having a locking apparatus (24) and for a tension rod (25) in the cabinet body (10), wherein the ejection piston (21) is supported in the unit (20) by means of a compression spring (23) and the tension rod (25) is supported in the unit by means of a tension spring (26). The ejection piston (21) and the tension rod (25) are coupled to each other by means of a control apparatus (27) having a freewheel, and thus by tapping (a) on the cabinet door the opening of the cabinet door (11) can be initiated and the cabinet door can be brought into an intermediate position. In the intermediate position, the cabinet door (11) can be grasped by a hand and opened further. The invention further relates to an additional embodiment of the device having the same functions.
Abstract:
Die Erfindung betrifft eine Vorrichtung zum Öffnen der Schranktüre eines Schrankkorpus, wobei die Schranktüre (11) mittels Scharnieren (12) mit Selbsteinzug am Schrankkorpus (10) angebracht ist, wobei die Schranktüre (11) in der Schließstellung in kleinem Abstand (x) zur Vorderseite des Schrankkorpus (10) gehalten ist. Damit das Öffnen der Schranktüre ohne Griffelemente ermöglicht wird, ohne den Selbsteinzug der Scharniere zu behindern, sieht die Erfindung im Schrankkorpus (10) eine Einheit (20) mit Auswurfkolben (21) mit Verriegelungseinrichtung (24) und eine Spannstange (25) vor, wobei der Auswurfkolben (21) mit einer Druckfeder (23) und die Spannstange (25) mit einer Zugfeder (26) in der Einheit (20) gelagert ist. Der Auswurfkolben (21) und die Spannstange (25) sind über eine Steuerungseinrichtung (27) mit Freilauf miteinander gekoppelt, so dass das Öffnen der Schranktüre (11) durch Antippen (a) derselben einleitbar und in eine Zwischenstellung bringbar ist. Die Schranktüre (11) kann in der Zwischenstellung mit der Hand gefasst und weiter geöffnet werden. Eine weitere Ausgestaltung der Vorrichtung mit denselben Funktionen ist in der Erfindung mit enthalten.
