Abstract:
An automatic opening/closing apparatus for vehicle, which is provided with a tensioner mechanism for applying a predetermined tension to a cable member, is downsized. A case of a driving unit is provided with a tensioner housing, and the tensioner mechanism for applying the predetermined tension to a cable is accommodated in the tensioner housing. The tensioner mechanism includes a pulley holder movably mounted on a guide shaft, and a spring for biasing the pulley holder, wherein a movable pulley is rotatably supported by the pulley holder. The cable drawn in the tensioner housing is wound about the movable pulley so that a direction in which the cable is drawn out from the case is substantially parallel to a direction in which the cable is drawn out from a driving drum, whereby the predetermined tension is applied to the cable by a spring force of the spring.
Abstract:
A drive arrangement for a shaft has a module carried by the shaft and including a motor, a driven wheel and a drive wheel. The motor, gearbox and drive wheel are carried on a slider plate which can slide transverse to the axis of the shaft. A front plate is fixed transverse to the axis of the shaft. A Bowden cable has its sheath attached to the front plate, and its inner cable attached to the slider plate, so that manipulation of the Bowden cable at a remote location allows force to be applied between the plates either tightening the belt to apply drive from the motor to the shaft, or releasing tension in the belt, to disengage the drive.
Abstract:
A door opening system includes a power transmission mechanism, a trolley, and a connecting arm. The power transmission mechanism includes a motor, a drive wheel driven rotatably by the motor, an indirect wheel, and a tension wheel. A transmission rope is trained on the drive, indirect and tension wheels in a closed loop such that parts of the transmission rope extend along a spiral path on the drive and indirect wheels, and do not contact each other, and such that rotation of the drive wheel drives the indirect and tension wheels rotatably. The trolley is coupled to the transmission rope, and is disposed between the indirect and tension wheels of the power transmission mechanism. The connecting arm has a first end coupled to the trolley, and a second end adapted to be coupled to the garage door.
Abstract:
A motorized operator for moving a barrier, such as an upward acting garage door, between open and closed positions includes a support mounted adjacent one of a pair of barrier guide tracks or along a barrier counterbalance shaft and a drive mechanism mounted on the support and engaged with an elongated flexible member, such as a chain, cable or cog belt. A cog belt, for example, is connected to a drawbar connected to the barrier at one end and the belt is either connected directly to the barrier at the opposite end or to a storage reel supported for rotation on and with a shaft of a barrier counterbalance mechanism. The storage reel may include a spiral groove and be supported on the counterbalance shaft for axial translation to receive and dereel the belt as the barrier is moved between open and closed positions. One or more belt tensioning pulleys may be mounted on the support.
Abstract:
A vehicle door drive unit for raising and lowering a glass plate is constructed so that a plurality of pulleys across which wires extend are provided at upper and lower sides of a base panel. The glass plate is supported by a carrier plate which is connected to the wire ends. The glass plate is moved up and down by the wires and is prevented from excessively moving in a vehicle inward direction when the door is closed by a supporting rod positioned along an upward and downward path of the glass plate and a contact member. Trumpet shaped guide portions are formed at the edges of holes of the wire fixing portions of the carrier plate and the circumferential surfaces of a V-shaped tensioner are provided for eliminating slack in the wires.
Abstract:
The invention relates to a deflection device for an adjustment device of a motor vehicle for the deflection of an elongate, flexible traction means which can be moved along a direction of extent by means of an adjustment drive and to which a motor vehicle part which is to be adjusted with the adjustment device can be connected. The deflection device comprising a support, at least one deflection element which is arranged on the support, a receptacle which is integrally formed on the support and protrudes from the support for the deflection element, an undercut which is formed on the receptacle and an elastic element which is integrally formed on the support or the deflection element and acts on the deflection element in such a manner that the deflection element tends to engage in the undercut of the receptacle.
Abstract:
A power slide device includes a first cable connected to a wire drum and moving in a first direction when wound up by the wire drum, a second cable connected to the wire drum and moving in a second direction when wound up by the wire drum, a first tension roller having a first abutting surface abutting against the first cable, and a second tension roller having a second abutting surface abutting against the second cable. The first abutting surface is taken as an inclined surface becoming gradually shorter in diameter toward the first direction, and the second abutting surface is taken as an inclined surface becoming gradually shorter in diameter toward the second direction.
Abstract:
An automation assembly is adapted to be connected to a door system of a motor vehicle. The automation assembly is modular and includes a frame that is fixedly secured to the motor vehicle. A motor is fixedly secured to the frame and adapted to receive power. The motor converts the power into a rotational output force. The motor includes a non-ferrous core. A set of pulleys and rollers are fixedly secured to the frame at predetermined positions to direct the path of a continuous belt. The continuous belt is fixedly secured to the door system such that the motor moves the continuous belt and the door system bidirectionally between an open position and a closed position. Sensors are used to determine the position of the door, the speed thereof and whether the door is being moved manually.
Abstract:
An automotive vehicle door has a glass window that is raised and lowered by a window regulator that includes a roller cable assembly (15). The roller cable assembly (15) has a rolled section guide rail (18) and a bracket assembly (16) at the lower end portion of the glass window that runs on an L-shaped flange (36) of the guide rail (18). The roller cable assembly (15) includes upper and lower roller assemblies (28 and 30) at the respective upper and lower ends of guide rail (18) and a cable (20) that is trained on rollers (22 and 24) of the roller assemblies and on a drive roller (26) that is driven by an electric motor (32). Each roller assembly includes a base (42) that is slideably attached to the guide rail (16) and a detachable cap pin (44) that attaches the guide roller to the base (42).
Abstract:
A door glass raising and falling apparatus has a carrier plate 71 mounted onto a door glass 70. The door glass 70 is movable along sashes 41, 42 disposed on a door. The carrier plate 71 includes securing portions that are fixed to moving portions 67a, 67b of a wire-rope body 67. The carrier plate 71 also has a glass support portion 74 for supporting the door glass 70, and a pair of front and rear glass fixing portions 77, 78 each including a screw member 75. The door glass 70 has mounting holes supported by the glass fixing portions 77, 78, respectively. The dimension of the mounting holes is larger than the outside diameter of the shaft portion of each of the screw members 75 so that the door glass 70 is moveable with respect to the carrier plate 71. Also, a wire-rope body 150 extends over a plurality of pulleys. Some of the pulleys 142, 143 are rotatably mounted on frame members 136, 137 by pulley shafts 182 respectively. stoppers 184 are mounted on the pulley shafts 182, to limit the falling distance of the glass rising and falling body 162.
