Abstract:
A clutch mechanism of a powered sliding device for a vehicle sliding door comprises a swingable member held at a neutral position by means of resilient force of a return spring, an output gear fixed to an output shaft of a motor, first gears rotatably supported to the swingable member and engaged with the output gear, second gears rotatably supported to the swingable member and brought into contact with the first gears with predetermined frictional resistance, respectively, rack members fixed to the base plate and engaged with the second gears, respectively, a wire drum connected to the sliding door through a wire cable, a drum gear integrally rotated with the wire drum. When the first gears and the second gears are rotated by the motor, the swingable member is rotated due to the engagements of the second gears and the rack members against the resilient force of the return spring so that one of the first gears is engaged with the drum gear. When the motor is not energized, the return spring returns the swingable member to the neutral position.
Abstract:
A collapsible cable regulator assembly is provided, having a collapsible support structure wherein one or more swing arms are pivotably mounted to a lateral member. Cable guide means are provided for mounting a regulator cable, including a cable return at the free end of each of the swing arms. The collapsible support structure is openable from a collapsed condition in which each swing arm is at an acute angle to the lateral member, to an operating condition in which each swing arm is at an operating angle to the lateral member which is greater than the aforesaid acute angle. The cable regulator assembly in its collapsed condition has improved installation capability, being especially advantageous for installation through limited access openings. Once in proper location, the cable regulator assembly is opened to its operating condition. The regulator assembly can then be permanently or non-permanently mounted in position, and a windowpane or other moveable member attached to mounting brackets or gliders driven by the regulator cable. In the operating position the swing arms act as guide rails with good parallelism aided by the lateral member acting as an interconnecting cross-member between the guide rails.
Abstract:
A door window regulator for vertically moving a door window glass of a vehicle includes a guide member which guides the vertical movement of the door window glass. A wire is stretched between pulleys respectively provided at the upper and lower portions of the guide member and is connected to the lower portion of the window glass, whereby the window glass is vertically moved by the driving force transmitted from a driving unit. The axis of either one of the pulleys extends in the direction substantially orthogonal to the plane which includes the portion of the wire which extends from that pulley to the driving unit and is directed toward the inside of the compartment of the vehicle, whereby the condition in which the wire is passed over the pulley is maintained in an appropriate state at all times.
Abstract:
A first and a second pulleys are rotatably supported at a fixed separation along a guide rail. A link arm is at one end pivotably connected to the axle of the first pulley and supports at the other end a drum which is rotatable manually or by an electric motor. A drive wire is fixed to the drum, sequentially wound around the first and second pulleys and finally secured to the drum. A window bracket, adapted to be secured to a window pane, is also secured to the wire so that rotation of the drum causes the wire and therefore the window pane to move along the guide rail. The regulator may include an additional pulley rotatably supported at a point opposite the first pulley with respect to the second pulley in which case, the drive wire is wound from the drum, around the first pulley, around the second pulley, around the additional pulley, around the first pulley again, and back to the drum. A device may be disposed near one of the second and additional pulleys to impart appropriate tension to the drive wire.
Abstract:
A patio door operating unit comprises a housing which mounts on the floor beside the location that the door occupies when the sliding door is in its open position. Within the housing in an endless belt which engages the door adjacent its bottom and is trained for movement along a path at the bottom of the door. This belt is driven by an electric motor. There are limit switches to stop the electric motor at the open and closed positions of the door. The belt is tightened by a solenoid connected to the motor circuit so that when the electric power fails the belt is loose and the door can be moved by hand.
