Abstract:
A winding device for cables which is used to wind cables round take-up drums along grooves 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 control apparatus and method are disclosed for controlling the output torque of a multiple phase stepper motor, by turning OFF the normally excited phases for predetermined periods.
Abstract:
A gate opener (14) is disclosed for attachment to a pre-existing gate (10) mounted for pivotal motion to a post (12). The gate opener includes a controller (30) for activation by an operator from a remote location, such as a vehicle, to transmit a signal of predetermined frequency to a receiver (32) mounted by the gate. The receiver (32) activates a relay to initiate operation of an electric motor (34) to open or close the gate. The rotating motion of the motor shaft is transferred through a set of pulleys (37, 39), a belt (43), gears (48, 54) and a chain (58) to a wheel (38) in contact with the ground. A gate opener (100) forms a second embodiment of the invention. The gate opener (100) is supported by a parallel arm hinge assembly (104) so that substantially the entire weight of the gate opener (100) is supported on the ground (40) through the ground wheel (132) to provide traction to the ground wheel. An open limiter switch (136) and a closed limiter switch (138) cooperate with adjustable contacts (140, 142) to deactivate the motor upon movement of the gate (10) into the opened or closed positions to permit the motor (116) and ground wheel (132) to continue rotation until the gate is either opened or closed.
Abstract:
An improved curved cable support member adapted to the ends of the rail guides of a Bowden window lift. This support member (2) comprises at least one projecting first catch means at its side facing the rail guide (1), the projecting catch means is undercut so that a free gap about the material thickness of the guide rail (1) exists between a free-standing lip (3) and the body of the support member, and the free-standing lip (3) is provided at its inside with a beak (4) entering a corresponding clearance (5) in the guide rail when the support member is slipped onto the guide rail and secures the support member against being pulled off the guide rail.
Abstract:
A device for indicating the failure of one of the cables in a redundant cable system for assisting the movement of a closure which includes means for so connecting each of the cables to a counterweight suspended therefrom that the counterweight is maintained at a first distance from the closure when both cables are intact and the counterweight so moves to a second distance from the closure when one of the two cables fails that the counterweight can move into a position for inhibiting the raising of the closure, thereby indicating the failure of one of the cables. The second distance is greater than the first distance. The connecting means is a pivoting member having two arms, each being adapted for sliding attachment to one of the cables.
Abstract:
An improved door elevating system for use with a door having a plurality of horizontal door panels hinged together at their horizontal edges and guided at their vertical edges between a pair of guide rails. The system comprises means to displace the door along the guide rails and having a door lifting cable secured at one end to a bottom portion of the door and extending along a vertical edge of the door. An opposed end of the cable is wound on a rotatable drum rotatably supported in alignment with the vertical edge. The drum has an outer cable receiving surface on which the cable can be wound. The drum further has a vertical bearing side face and a free side face. The free side face faces inwardly of the door and a cable passage is provided inside the drum and has an exit port in the free side face whereby the opposed end of the cable exits. An adjustable fastening means is provided to secure the cable in the passage.
Abstract:
A compact and thin wire-driving device for a window regulator which absorbs elongation of wire automatically, wherein both ends of a driving wire are wound round two pulleys arranged parallel, i.e. a first pulley and a second pulley, in the same direction; a first gear is secured coaxially to the first pulley; a second gear is adjacent coaxially to the second pulley through ratchet teeth; the first gear and second gear are meshed to each other; and, when the wire is wound up round the first pulley, a slack of the wire is wound up round the first pulley and the second pulley remains stopped.
Abstract:
The bowden cable drivingly connecting a crank on a motorcar door to a carrier for the window in the door has a plastic compression member whose ends abuttingly engage retaining members near the crank and the window carrier. The ends are of non-circular cross section, and their angular movement about the longitudinal axis of the cable is prevented by conforming engagement with respective retaining members.
