Abstract:
A power-operated system (32) for actuating the rear doors or liftgates (18) of motor vehicles (10) is disclosed. The system includes a strut assembly having two struts (30), each strut mounted on one side of the door between the door and the vehicle's door frame. One end of each strut (30) is connected to a powered moving arm (40). To open the door, the arms (40) move to change the angular orientation of the struts (30) such that they have a substantial mechanical advantage. In this position, the force provided by the struts (30) overcomes the weight bias of the door (18), thus opening the door. To close the door, the moving arms (30) change the angular orientation of the struts (30) such that the struts have a decreased mechanical advantage, reducing the force provided by the struts, and therefore allowing the door (18) to fall closed under its own weight bias. A control system for controlling the power-operated system (32) is also disclosed.
Abstract:
A sliding door or the like (10) driven by a motor (16) is controlled by the use of a motion detector (25) coupled with the door. Pulses from the motion detector are counted by control circuitry, and the door is moved at a reduced speed in the region of its limits of travel. The limits are defined by the number of pulses from the motion detector equalling a predetermined value. The motor is de-energized if a stationary state of the door is detected in the low speed region, and reversed if a stationary condition is detected in the remainder of its movement.
Abstract:
Zur Optimierung einer Torflügelbewegung schafft die Erfindung eine Torantriebsvorrichtung (12) zum Antreiben eines Torflügels eines Tores, mit einem Elektromotor, einem durch den Elektromotor antreibbaren Torantriebsgetriebe (10), sowie einer an eine Drehwelle des Torantriebes angeschlossene Torflügelpositionserfassungseinrichtung (14) zum Erfassen einer Torflügelposition, wobei die Torflügelpositionserfassungseinrichtung (14) einen an einer Getriebeabtriebswelle (18) des Torantriebsgetriebes (10) vorgesehenen Drehgeber (34) zum unmittelbaren Erfassen einer Drehwinkelposition der Getriebeabtriebswelle (18) umfasst.
Abstract:
Die Erfindung betrifft einen Türfeststeller für eine Fahrzeugtür, umfassend eine Haltestange (20), die an einem von beiden Türanordnungsteilen Tür (8) und Türrahmen (6) anschließbar ist und ein Haltegehäuse (13), das an dem anderen Türanordnungsteil anschließbar ist. Ein Türfeststeller, der ein zuverlässiges und sicheres automatisiertes Feststellen einer Fahrzeugtür ermöglicht, wird erfindungsgemäß dadurch geschaffen, dass eine Spindelstange (50) in einem Hohlraum der Haltestange (20) axial verschiebbar aufnehmbar ist.
Abstract:
The invention relates to a door drive (1) arranged on a door leaf, a door frame, a door lintel, a wall or the like, said drive comprising a drive unit (2) provided with at least one motor (3) and a transmission (4) co-operating with a closing shaft (5). According to the invention, the drive unit (2) comprises a shaft encoder (6) which provides information on the position and/or the movement of the door leaf by means of an electrical signal.
Abstract:
An apparatus for opening and closing a deck lid of a vehicle body includes a jack-screw type drive unit having two elongated relatively rotatable drive elements which are threadably engaged for controlled bi-directional displacement. An electric motor engages the rotatable drive element. A first mounting device pivotally connects the rotatable drive element to a relatively fixed point on the vehicle. A second mounting device pivotally connects the non-rotatable drive element to the deck lid, or vice versa. The motor is energized to affect bi-directional control of the drive unit while enabling low back-drive effort. A concentric spring counters loading due to the weight of the deck lid.
Abstract:
A method and system for monitoring a movable partition. In one embodiment, the system includes a sensor (25) linked to a movable partition (15), a drive system (20), and a controller (30). The drive system (20) is configured to move the movable partition (15). The sensor (170), which in one embodiment includes a drum (160) connected to the partition by a cable (155), is independent of the drive system. The sensor (170) transmits a signal indicative of the rotational motion of the drum (160) to the controller, which receives the transmitted signal and calculates at least one of a speed, acceleration, position, and direction of movement of the movable partition.
Abstract:
A mechanical memory as used with a movable barrier operator serves to provide characterizing codes and/or executable code to the movable barrier operator. In one embodiment the mechanical memory is integrated with an RPM cup (20). The mechanical memory includes physical aspects that interact in a predetermined way with energy such as for example, light. This interaction can include passage, reflection, and absorption. Regular placement of at least some of the physical aspects can be used to permit real-time monitoring of at least one operating parameter of the movable barrier operator (such as motor speed or movable barrier position). In addition, these and/or additional physical aspects can be modified to correlate to data, such as or symbols, that represent the operator code.
Abstract:
The invention pertains to the operating mode of an electromotive actuator for a lifting sun roof in a vehicle (16), involving a signal processing unit (20) with a microprocessor to which a signal on the actual position and a command (23) from an actuator (22) for positioning as prescribed the lifting sun roof (16) are transmitted, as well as another signal on the snapshot position of at least one element (26, 32, 34, 52, 54) designed to determine the actual position of the actuating mechanism (10) and/or the lifting sun roof (16), and which controls or adjusts the actuator (10) enabling the lifting sun roof to be positioned as prescribed. The microprocessor (21) permits snapshot-position signals to be cyclically input and, based on the signal combination, a response from the memory to be read out, from which response it can be seen whether and how any kind of manoeuvring (22) with the actuator can generate via the signal processing unit (20) a change in the actual behaviour of the actuating mechanism.
