Abstract:
A guide rail assembly for moving a closure panel of a motor vehicle between an open position and a closed position includes a guide rail fixedly secured to the motor vehicle. A slide mechanism slidably engages the guide rail. A rod has one end coupled to the slide mechanism and an opposing end coupled to the closure panel to move the closure panel as the slide mechanism slides along the guide rail. A drive is fixedly secured to the guide rail for selectively driving the slide mechanism along the guide rail. A clasp is operatively secured to the slide mechanism for selectively coupling the drive to the slide mechanism such that the drive moves the slide mechanism along the guide rail to move the closure panel between the open and closed positions when the slide mechanism is coupled with the drive.
Abstract:
A power operator assembly is provided for moving a sliding door between a sliding door of a motor vehicle between a closed position and an open position. The power operator assembly includes a guide rail fixedly secured to the motor vehicle and defining a rail length. A slide mechanism slidingly engages the guide rail. A drive is fixedly secured to the guide rail for selectively moving the slide mechanism along the guide rail in either direction. First and second cables each extend between the sliding door and the slide mechanism for moving the sliding door as the slide mechanism is driven along the guide rail. A compound pulley set is operatively connected to the drive and receives the first and second cables for powered movement of the sliding door a multiplied distance greater than the rail length as the slide mechanism is driven along the guide rail.
Abstract:
A safety cabinet has a body, a pair of doors each pivotal on the body about a respective axis between an open position and a closed position, respective spaced outer guides on the body juxtaposed with the doors, and respective elements displaceable along the guides and coupled to the doors for movement between outer positions when the respective doors are in the open position and inner positions when the respective doors are in the closed positions. A catch between the guides is engageable with the elements and shiftable therewith. A spring also between the guides is engaged between the catch and the body and biases the catch inward toward engagement with the elements. A release device secured between the catch and the body normally holds the catch in an outer position with the spring in a tensioned condition but can release the catch and thereby push the elements with the catch into their inner position to close the doors.
Abstract:
Embodiments of the invention provide a control system for a garage door. The control system can include a motor, a pulley, a synchronous drive member, a carriage, and an operator. The pulley can be coupled to and driven by the motor. The synchronous drive member can be coupled to the pulley and driven by the pulley. The carriage can be coupled to the synchronous drive member and to a bottom edge of a garage door. The operator can be coupled to the motor and can control the motor. The operator can be mounted vertically adjacent to the garage door when the garage door is in a closed position.
Abstract:
A motorized door opener for a vehicle (such as a military or security vehicle), featuring a sensor system that determines door position to prevent door damage while the opener is in operation. The opener features an offset gear system that effectively changes the door's rotation point. Mechanical advantage is gained by using a lengthened lever arm with the gear system, providing increased leverage and allowing the motor to provide enough force to open and close a heavily armored door. The opener can use existing door hinges, and can be provided so as not to protrude into the door space, in order to facilitate passenger and equipment entry/exit through the doors. A safety release mechanism is included in some embodiments, allowing the door to be manually opened or closed.
Abstract:
A safety release mechanism for use with a ball screw type linear motor, featuring a lock lever that can be manually engaged or disengaged. Engaging the lock lever rigidly fixes a telescoping arm, allowing the motor to retract or extend the arm into a cover tube. Disengaging the lock lever allows the telescoping arm to rotate freely in the cover tube. One embodiment of the safety release mechanism is used with a motorized door assist mechanism, however, the release mechanism has many applications beyond a door opener, and can be used in any application requiring a linear motor with a telescoping arm, where in order for the motor to extend or retract the arm, one end of the arm must be fixedly held in place.
Abstract:
A system for dynamic braking a vehicle closure including a drive mechanism mounted to the vehicle, the drive mechanism having contacts to receive a drive signal to cause the drive mechanism to move the vehicle closure between an open and a close position in response to the drive signal, the drive mechanism capable of generating a generated drive signal during at least a portion of the vehicle closure from the open to the close position; and a controller having electrical outputs electrically coupled to the electrical contacts of the drive mechanism and electrical inputs to provide the drive signals to the drive mechanism and to receive generated drive signals from the drive mechanism, the controller configured to provide the generated drive signals back to the drive mechanism during operation of the vehicle closure to provide dynamic braking of the vehicle closure from the open to the close position.
Abstract:
The invention pertains to a method of motorized movement of a vehicle door, wherein the vehicle door can be moved from an open position to a closed position as part of a closing process, wherein a door drive mechanism associated with the vehicle door and a control system are provided, wherein the vehicle door can be moved in the direction of closing starting from the open position using the door drive mechanism. It is proposed that in a first section of the closing process the vehicle door is moved by the door drive mechanism from the open position to a comfortable open position that lies between the open position and the closed position, and that in a second section of the closing process, the vehicle door is further moved from the comfortable open position in the direction of closing, preferably to the closed position, manually by the user and largely free of the door drive mechanism.
Abstract:
A power drive assembly for a rear lift gate assembly of a vehicle includes a screw drive having a screw member and a clutch supported by the screw member.
Abstract:
In an electric motorized hinge apparatus, a biasing means maintains a concavo-convex engagement state between a third rotating member and a second engagement portion in a second rotating member, and thus the second rotating member rotates to follow the third rotating member. Furthermore, the biasing means maintains a concavo-convex holding state between a first engagement portion in the second rotating member and a first rotating member, and thus the first rotating member rotates to follow the second rotating member. Furthermore, as the first rotating member rotates, a lid portion rotates to follow it. During manual rotation of the lid portion, a motor is maintained in an off state and the second rotating member is kept at a stop by a lock means. Therefore, the engagement state at the first concavo-convex engagement part is released by the manual rotation of the lid portion, so that the lid portion can be freely rotated by hand.
