Abstract:
A vehicle (10) has a sliding door (14) mounted on rollers (22, 24 and 30) that are supported by and slidable in tracks (16, 18 and 20). A front cable is attached to the front cable drive pulley (144), and extends from the pulley through a front cable roller guide assembly and is attached to the hinge and roller assembly (26). A rear cable is attached to the rear cable drive pulley (136) and extends from the pulley through a rear cable roller guide assembly and is attached to the hinge and roller assembly (26). A motor rotates the front and rear cable drive pulleys to move the sliding door. A slack cable take-up pulley (174) on the rear cable drive pulley (136) takes up slack cable to set cable tension and is then locked in position.
Abstract:
57 A winding device for cables which is used to wind cables round take-up drums (5,6) along grooves (7,8) provided on the outer circumferences thereof, said grooves formed such that the cables will not cause chafing against the side walls of the grooves, so that no unusual noise is caused or the cables will not be worn severely during operation. This winding device can be applied to a window regulator for automobiles.
Abstract:
A counterbalance system for balancing an overhead door installed against a structure of a vehicle or a house, the door having at least one door panel, the system has a longitude pipe with non-circular section cut; a pair of U-brackets having two side walls with one center hole on each side; a pair of torsion spring assemblies received within the pipe, and the inboard end of the assembly being slidingly engaged within the pipe; a pair of connecting shaft, with inboard side connected with the outboard end of each of the spring assemblies; the shaft passing through the center holes of the U-bracket; the outboard end of each shaft being fixed with the side wall on the outboard end of each of the U-brackets; a pair of drums each having a center hole received by the shaft, and each of the drums located between two side walls of the U-bracket.
Abstract:
A cable drive device of an adjustment system of a motor vehicle has an actuating drive and a cable drive housing in which a cable drum that is rotatably coupled to the actuating drive and has a traction cable wound thereon is received. The cable drum, for receiving a cable nipple fastened to the traction cable, on at least one end side has a nipple chamber having a chamber opening and mutually spaced apart chamber walls. The nipple chamber on at least one of the chamber walls has a delimiting element. The cable nipple when introduced into the nipple chamber by way of the chamber opening engaging below the delimiting element.
Abstract:
A threaded drum is rotated by a drive shaft. As the threaded drum rotates, part of a cable is wrapped around the drum, while at the same time, a second part of the cable is unwrapped from the drum. Rotation of the drive shaft is based on rotation of an operator.
Abstract:
The contact-free detection device for detecting the position of a winding drum (2) for a handling door is made up of a cam or code wheel (3) secured to the winding drum (2), inductive sensors (4, 5) positioned near the cam or code wheel (3), and an electronic board (7) including at least one prevention and security module (12) receiving the pulses generated by the inductive sensors (4, 5) so as to ensure the security of the rotation command of the driving axis of the winding drum (2) of the handling door.
Abstract:
A cable lift mechanism for a multi panel, overhead garage door includes a drum having a spiral groove comprised of two adjacent sections that are generally coaxial with the longitudinal axis of the cable drum. The groove or grooves in a first section adjacent the attachment end of the cable to the drum have a lesser radius than the remaining grooves of the second section of the drum which have substantially equal radii of greater diameter than the first section radii. As a consequence, initial torque associated with lifting of a garage door is increased to lift a heavier upper or top panel or panels of a multi-panel garage door.
Abstract:
A door assembly is provided that includes integral impact regions that obviate the need for a separate impact beam. The door assembly includes an outer panel and an inner panel, operably connected to the outer panel so that a compartment is formed therebetween. At least one hardware-mounting surface is integrally formed from the inner panel and extends towards the outer panel. Each of the hardware mounting surfaces is operable to mount a hardware component between the inner and outer panels. At least one integrally-formed impact region is provided on the inner panel that is operable to strengthen the door assembly and increase its intrusion resistance of the vehicle door during a collision. The inner panel has substantially no large access openings that would be deleterious to impact resistance and substantially seals the vehicle passenger compartment from the external environment. The at least one impact region is also displaced at least as far away from the outer panel as the at least one hardware mounting surface.
Abstract:
A power closure actuator especially suitable for use in powering various automotive closure devices. The actuator includes a brushless pancake electric motor having an output shaft; a sun gear on the output shaft; a plurality of compound planet gears each having a large diameter lower portion meshingly engaging the sun gear and a small diameter upper portion; a ring gear surrounding and meshingly engaging the small diameter upper portions of the planet gears, and a cable drum splined to the ring gear. A mounting plate positioned in overlying confronting relation to the flat upper face of the motor mounts a plurality of planet shafts extending upwardly from the mounting plate in circumferentially spaced relation to the motor output shaft with one of the compound planet gears journaled on each planet shaft.
