Abstract:
The door glass raising and falling apparatus comprises a carrier plate 71 to be mounted onto the lower end portion 70b of a door glass 70. The door glass 70 is capable of rising and falling along sashes 41, 42 respectively disposed in the front and rear portions of a door. The carrier plate 71 extends in the back-and-forth direction of the door glass 70 along the lower end of the door glass 70 and includes securing portions respectively formed in the given portions of the carrier plate 71, while the moving portions 67a, 67b of a wire-rope body 67 can be respectively fixed to the securing portions of the carrier plate 71. The carrier plate 71 further comprises a glass support portion 74 for supporting the middle portion of the lower end of the door glass 70 in the back-and-forth direction thereof, and a pair of front and rear glass fixing portions 77, 78 each including a screw member 75. In the door glass 70, there are formed mounting holes which can be supported by the glass fixing portions 77, 78, respectively. The dimension of each of the mounting holes is set sufficiently larger than the outside diameter of the shaft portion of each of the screw members 75 so that, when the screw members 75 are loosened, the door glass 70 can be moved with respect to the carrier plate 71. Also, the door glass raising and falling apparatus further comprises a wire-rope body 150 for raising and falling a glass rising and falling body 162. The wire-rope body 150 is wired over and between a plurality of pulleys. Of these pulleys, pulleys 142, 143, which are situated on the lower side, are rotatably mounted on frame members 136, 137 by pulley shafts 182 respectively. Rubber stoppers 184 are mounted on the pulley shafts 182, respectively. The rubber stoppers 184 are structured such that, when the glass rising and falling body 162 reaches its falling limit, the lower end face of the glass rising and falling body 162 can be contacted with the rubber stoppers 184.

This invention relates to a window lifter comprising a window connecting element; a cable drive motor element, offset from the travel of the connecting element, a first and a second cable return which returns are arranged at one end of the travel of the connecting element and superposed, a third cable return arranged at another end of the travel of the connecting element, a cable secured to the window connecting element. This window lifter has, in particular, greater compactness.
Abstract:
A cable deflection pulley pertaining to a window lifter comprising a drive unit, a guide rail for a driver which is connected to the window and to the cable, and cable deflection pulleys with a guide or bearing groove for the cable. The device has an axially directed assembly groove in the proximity of the bearing groove to facilitate and accelerate assembly and to reduce the amount of cable required. The assembly groove contains an area adjacent to the axis of the cable deflection pulley, and an area adjacent to the bearing groove, through which the cable is pulled from the assembly groove into the bearing groove.
Abstract:
In a system for automatically opening or closing a sliding door or the like for a vehicle, an undesired clamping of an object between the door and the vehicle body, resulting in increased tension force in the wire moving the door, is sent early and relieved quickly. The wire (4) is solidly secured to the sliding door and wound onto a drum (10) to open or close the door by a motor driving the drum, and two tensioners (11a and 11b) are provided respectively on opposite sides of the drum and between the drum and door. Each sensor has a movable part (19) positioned in accordance with the tension force in the wire passing through the tensioner, sensor plates (20) are provided on the movable parts of the tensioners, and magnetic sensors (21) are provided to detect the moving speeds of the plates. When the moving speeds of the plates are larger than a predetermined value, preset in advance, in cases other than when the door is at a fully closed or fully opened condition, a controller concludes that some object has been clamped between the door and the vehicle body and immediately relieves such clamping.
Abstract:
A powered sliding device for sliding a vehicle sliding door along a guide rail comprises a base plate fixed to the vehicle body, a wire drum rotatably mounted on the base plate and rotated by a motor, a wire cable provided between the wire drum and the sliding door, a first holder provided in the vicinity of one end of the guide rail and having a first pulley making contact with the wire cable, a second holder provided in the vicinity of the other end of the guide rail and having a second pulley making contact with the wire cable, a tension roller provided on the base plate for making contact with the wire cable by resiliency of a spring, a flexible cable sheath covering the outer periphery of the wire cable between the first holder and the base plate and having one end to be connected to the first holder, a supporting member connected to the other end of the cable sheath. The supporting member is slidably mounted to the base plate in parallel with a running direction of the wire cable.
Abstract:
A powered sliding-door system of an automobile with a sliding-door drive device A and an automatic door closer B. The sliding-door drive device A has a case body 1 opening downward, a case cover 2 covering the opening of the case body 1. A pair of guide pulleys are rotatably supported by axes, and each axis stands on the front end and the rear end of the case in slanting posture. A loop of cable is arranged between the pair of guide pulleys so that a working side is arranged outside of the case body and a return side is arranged in the case body. The loop of cable is driven by an motor driven actuator 12.
Abstract:
An elevator car has a drive mechanism mounted in a compact housing on the upper surface of the car. The drive mechanism includes a rotatable drive shaft, around which is mounted a linear actuator block having a plurality of ball bearings, obliquely arranged relative to the shaft, and firmly touching the shaft. Rotation of the shaft by a motor makes the block move linearly along the shaft. A bracket attached to the block carries an elevator door. Rotation of the shaft therefore opens and closes the door. The direction of movement of the block, and hence the door, depends on the direction of rotation of the shaft. The drive mechanism is compact and simple, and can be applied to new elevators or can be used to retrofit existing elevator cars.
Abstract:
A cable window winder, particularly for installation in motor vehicles, which has at least one guide rail with a slide element guided therein and connectable with the window pane, at least one holding angle (3) connected to the guide rail and supporting at least one guide pulley (31), as well as fastening means (32) for fitting the cable window winder. According to the invention one of the fastening means (32) is mounted in the rotary axis of the guide pulley (31) and is connected directly to the metal vehicle plate.
Abstract:
A tensioning device for an elevator air cord that forms a loop has: a support having a relatively accessible first surface and a relatively inaccessible second surface; a holder on the second surface for fixedly holding a first end of the air cord; a tensioning device on said second surface for holding a second end of said air cord such that the tension of the loop of air cord may be adjusted; and key communicating between the first and second surfaces for manipulating the tensioning device to adjust the tension of the air cord loop.
Abstract:
A mechanism particularly well suited for converting bidirectional rotation, as of a reversible electric motor or a hand crank, into the linear up and down motion of a windowpane relative to the frame of a passenger car door. Included is an elongate guide rail gently curved longitudinally to conform to the vertical curvature of the vehicular door and providing a vertical guideway on its convex side. A wire rope or cable is looped about a pair of terminal guide pulleys or nonrotatable guides on the opposite ends of the guide rail. One of the two stretches of the cable is coupled to a windowpane carriage which is coupled to the windowpane for joint up and down movement therewith along the guideway. A drive mechanism including a drive reel is mounted to the guide rail and coupled to the other stretch of the cable for bidirectionally driving the windowpane carriage along the guideway. The drive mechanism is compactly disposed on the concave side of the guide rail for minimal space requirement.
