Abstract:
Die Erfindung betrifft eine Torantriebsvorrichtung, insbesondere zum Antreiben eines zumindest teilweise anzuhebenden Tores, mit einem Elektromotor mit einem Rotor (14) und einem Stator (17). Um einen sicheren Torantrieb mit besseren Wirkungsgrad zu schaffen, wird vorgeschlagen, dass eine Halte- und/oder Bremseinrichtung (132, 18) zum Halten oder Bremsen des Rotors (14) in Ruhezeiten und/oder Störfällen vorgesehen ist.
Abstract:
L'invention concerne un dispositif d'obturation d'une baie ménagée dans la carrosserie d'un véhicule automobile, comprenant une structure fixe (11) dans laquelle est définie une ouverture (12), et au moins un panneau coulissant (13) présentant un cadre (132) portant au moins deux pions de guidage (21, 22). Selon l'invention, un tel dispositif d'obturation comprend : - au moins un coulisseau (25) présentant une gorge de réception pour chacun desdits deux pions de guidage (21, 22), lesdites gorges étant sensiblement identiques et présentant une portion inclinée formant un angle compris entre 1 et 89° avec ledit axe de coulissement; un élément de guidage solidaire dudit panneau coulissant (13), guidés dans un desdits rails (14) de guidage; et des moyens de rappel destinés à contrôler un mouvement relatif du ou desdits coulisseaux (25, 31) par rapport audit élément de guidage suivant ledit axe de coulissement, de façon à permettre un déplacement dudit panneau coulissant (13) suivant une direction perpendiculaire au plan de ladite structure fixe (11).
Abstract:
The invention relates to a locking unit for a first flap, a second flap and a carrier, comprising a locking element (101, 201) which can be housed in a displaceable manner on the first flap and which comprises a tappet (120; 253), and a driveable actuation device (112; 212) which is used to displace the locking element (101; 201). In a first position, said locking element (101; 201) couples the first flap to the second flap in order to form a unit, and in a second position, the first flap is released from the second flap, and in an intermediate position, the first flap and the second flap are fixed together in the carrier. An active connection between the tappet (120; 253) of the locking element (101; 201) and the actuation element (112; 212) can be formed in said intermediate position.
Abstract:
The invention relates to a drive arrangement for the electric adjustment of a functional element (1) in a motor vehicle. A drive motor (2), which adjusts the functional element (1) in an electrical manner in two adjustable directions, is provided and the drive motor is drivingly coupled to the functional element (1) by means of a first drive train (3) and a second drive train (4). The drive force is transmitted, simultaneously via the two drive trains (3, 4), at least in an adjusting device, during the electrical adjustment of the functional element (1). One of the two drive trains (3, 4) comprises a cable pull transfer (5) comprising a drive cable (6) which is used to transfer drive force. According to the invention, only one of the two drive trains (3, 4), primarily the second drive train (4), has a cable pull transfer (5) which is used to transfer drive force and the first drive train (3) is embodied in a cable pull free manner.
Abstract:
An electric roller door drive system (10) is described enabling also selective manual operation of the associated door by means of a manual drive wheel (26) coupled to a power output (18) (which the motor (16) can also drive) so as to enable manual movement of the door between the open and closed positions. A clutch mechanism (30) has a normal default condition and an electrically initiated motor drive enabling condition, the clutch mechanism in the normal default condition enabling the manual operation and, in its motor drive enabling condition, functioning so as to firstly disable the manual drive mechanism so that manual rotation of the manual drive wheel (26) does not transfer drive through the power output (18) to move the door; and secondly enable operation of the drive motor. The clutch mechanism is electrically operated to change from its normal default condition to its motor drive enabling condition when the electric drive mechanism is to be operated to drive the associated door between its open and closed positions. The manual drive wheel (26) in the normal default condition of the clutch is biased by a biasing spring means (31) into its operative position, and electrornagnetically operable displacement means (41) is operative upon supply of electric power thereto to displace the manual drive wheel against the bias of the biasing means away from its operative position and into its idling position.
Abstract:
An unlock mechanism for a rotary door operator of a transit vehicle includes a pivotally disposed unlock member adapted for rotating a lock member into an unlock position and activating a valve for discharging the fluid pressure from the drive cylinder to enable manual opening of the door. A spring is provided for biasing the unlock member to a non-activated position. The unlock member may be activated either with a cable or a lever handle. A lock sensing switch provides a feedback on the lock condition to the transit vehicle control system. Additionally, a guiding bracket is provided for securing the cable in proximity of the unlock member.
Abstract:
Die Erfindung betrifft einen Türantrieb, insbesondere die Türverriegelung, von Schienenfahrzeugen, aufweisend einen Spindelantrieb, dessen Spindel mit einem Freilauf verbunden ist, der die Drehung der Spindel in der Richtung, die der Schliessrichtung der Tür entspricht, gestattet und die Drehung der Spindel in der Richtung, die der Öffnungsrichtung entspricht, verhindert, wobei der spindelferne Teil des Freilaufs (1) drehbar, aber durch eine von einem Hubmagneten (8) lüftbare Kupplung (3, 6) lösbar fixiert bezüglich einer Lüftungsvorrichtung (2) gelagert ist. Die Erfindung ist dadurch gekennzeichnet, dass die Bremse, Kupplung od.dgl. in ihrer Offenposition fixiert oder fixierbar ist, und dass ein Schliessmagnet vorgesehen ist. In einer ersten Variante ist die Kupplung (3, 6) durch ein Gestänge (9) betätigbar, und zwischen der gelüfteten Position des Gestänges (9) und der verriegelten Position des Gestänges (9) liegt eine Totpunktlage. In einer zweiten Variante wird die Offenposition durch einen Permanentmagneten gehalten.
Abstract:
A system and method for decoupling a barrier from a barrier movement apparatus for the manual operation of the barrier. Advantageously, the decoupling is performed in response to a wireless signal and may be done only when the barrier is determined to be in a safe position.
