Abstract:
Die Erfindung betrifft einen Antrieb einer an einem Fahrzeug vorgesehenen Klappe, insbesondere einer Motorhaube (3), mit einem Elektromotor, einer Betätigungswelle (11), die mit der Klappe verbunden ist, einem Untersetzungsgetriebe, durch das der Rotor (27) des Elektromotors an die Betätigungswelle (11) angekoppelt ist, und einem Kraftspeicher, durch den die Betätigungswelle (11) unabhängig vom Elektromotor antreibbar ist. Bei diesem Antrieb ist das Untersetzungsgetriebe so ausgebildet, daß die Betätigungswelle (11) in einer Drehrichtung (B) nur vom Kraftspeicher angetrieben wird und der Elektromotor die Betätigungswelle (11) in der Gegendrehrichtung (A) antreibt und dabei dem Kraftspeicher die Energie zuführt, die zum Antrieb der Betätigungswelle (11) in Drehrichtung notwendig ist.
Abstract:
Support and operating device for sliding doors, in particular for wardrobe cabinets, wherein the doors (6) are moved from a closed and lowered position, to an open and raised position, shifted forward in relation to the closed doors, and vice versa. The device comprising one upper group of component parts and one lower group of component parts for each door (6), suitable for determining the movement of the door in such a way that it is always kept in its correct parallel and orthogonal position in all the shifted positions thereof.
Abstract:
Dispositif (1) de fermeture automatique d'un ouvrant coulissant, notamment une porte (2) de placard, comprenant au moins un boitier (4) fixé en bas ou en haut de la porte (2), et un axe sur lequel est montée une roue (3) coopérant avec un rail de guidage (5) de la porte (2), caractérisé en ce que la roue est intégrée au boitier (4) et est assujettie à un ressort spiral (6) dont une extrémité externe (6a) est solidaire d'un point fixe (7) du boitier (4), et dont l'autre extrémité (6b) est solidaire d'un point (8) de la roue (3), ou inversement, de manière que lors d'une rotation de celle-ci dans un sens d'ouverture de la porte (2) s'effectuant manuellement, le ressort (6) s'enroule et emmagasine de l'énergie, qu'il restitue à la roue (3) qui devient motrice, pour un retour en fermeture automatique de la porte (2).
Abstract:
Actuator has drive shaft (11) connected to bonnet and connected by transmission to rotor (27) of electric drive motor. Drive shaft can also be driven by stored power source independently from motor. Transmission has gear (35) with meshing gear (37). One part of circumference of first gear has no teeth to allow free movement in which auxiliary power source is connected. Auxiliary power source can be coil spring (39).
Abstract:
A safety mechanism for a closing installation, comprising a shaft and an element having teeth for cooperating with a catch which oscillates during rotational movements of the shaft. The mechanism further comprises a safety system including a ring for braking the oscillatory movement of the catch. The movement of the ring is controlled by a detecting system that detects the state of a spring which used to compensate the torque exerted on the shaft by the screen body.
Abstract:
A support mechanism supports a hood (10) in a raised position with respect to a vehicle to which the hood (10) is pivotally coupled. The support mechanism (14) includes a pivotal lift rod (40) coupled between the vehicle and the hood (10). The mechanism (14) also includes a pair of arm members (16, 30) which are pivotally coupled to each other by a central pivot pin (24), and which are coupled between the vehicle and a central portion (54) of the rod (40). A flat coil spring (60) is coiled around the central pivot pin (24) and is attached to the arm members (16, 30). The spring (60) is biased to pivot the hood (10) upwardly. The lower end (42) of the rod (40) is anchored by a removable pivot pin (44), which, when removed, permits the hood (10) to be raised approximately 90 degrees from it lowered position.
Abstract:
The invention relates to an automatic door, especially a sliding door, which is provided with a drive device (2) for opening and closing the door. A metal spring in the form of a flat spiral spring (10) is used as the mechanic energy storage device (9) which stores energy when the door is being closed and releases the stored energy for opening the door when the drive device (2) breaks down. Said spring is arranged around a drive shaft (6) and is under tension when the door is being closed. A rubber rope can be provided instead.
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').
