Abstract:
The subject is a slide gate or a slide door. There is a DC electric motor which is battery powered. The source of electricity can be from an AC power source such as 110 or 120 volts. A transformer and a converter change the voltage to about 24 volts and rectify the current from alternating current to direct current. There is the electric motor and gear box combination connecting with a drive pulley. Further, there is a pulley on a spaced-apart post. A cable runs around the two pulleys. The drive pulley is connected to the slide gate or the slide door for moving the gate or door.
Abstract:
An articulation arrangement connects individual elements of a folding structure which consists of two or more individual elements and is configured to be unfolded and locked in an unfolded position and swivellably disposed on a central body. The arrangement comprises two hinge parts each rigidly fastened at one of two adjacent individual elements and swivellable about a common hinge axle, a slotted disk provided with a slot and forming part of one of the two hinge parts, a lever swivellably disposed on the other of the two hinge parts and provided with a pin. The pin is configured and arranged such that, before the unfolded position is completely reached, the pin slides on an edge of the slotted disk and, in the completely unfolded position at which locking occurs, the pin is engaged in the slot. For unlocking of the folding structure there are provided a rotatable cam plate with an edge curve of changing radius to disengage the pin and pulleys as well as driving and transmitting devices to rotate the cam plate and to transmit the rotation to the respective adjacent elements.
Abstract:
A thin window regulator which can be assembled easily and which requires less installation space inside a door panel is disclosed. Both longitudinal ends of a belt are connected to a pair of sliders and the belt is made into a ring shape. Sliders are movable along a guide rail and are biased closer to each other by springs. Thus, since the ring-shaped belt is wound around a sprocket and the sliding portion, tension is not reduced by a creep phenomenon and the belt does not loosen. One end of the ring shaped belt is formed to be wound around the sliding portion. Thus, the window regulator can be made thinner compared with prior art systems in which both ends of a belt are wound around pulleys and a required installation space inside the door at the upper portion of the guide rail can be made thinner.
Abstract:
A gate opening apparatus which utilizes a horizontably swingable arm assembly which is to be operated electrically to effect movement of a gate between a closed position and an open position. The arm assembly is mounted through a latching mechanism to the motor mechanism of the gate opening apparatus. This latching mechanism can be manually released which will permit the arm assembly to pivot through a vertical plane so as to provide for manual movement of the gate between the open and closed position during instances when electrical power is not available to operate the gate opening apparatus.
Abstract:
An apparatus is provided for operating a segmented sliding overhead door. The door is of the type for sliding in a pair of side tracks mounted at either side of the door between a dosed vertical position and an open horizontal position. A driver is mounted at the side-to-side center of the door and extends away from an interior side of the door. The driver includes a screw drive shaft adapted to be mounted horizontally above the door. A motor is engaged with the drive shaft and provides reversible rotational drive force to the drive shaft. A drive shaft coupling unit engages the drive shaft for moving along the drive shaft in response to rotation of the drive shaft. A track assembly engages and supports the rotating drive shaft and guides the coupling unit in linear travel along the drive shaft. A door connecting rod assembly serves to rigidly jam the door against the floor when the door is in the fully closed position, and connects the carrier unit to the door for moving the door along the side tracks. Preferably, a safety release is included for releasing the connecting rod assembly from the door so that the door may be manually operated. The apparatus is particularly shock resistant.
Abstract:
Control systems including control circuitry and optional communications systems for operating a sliding power-operated member of an automotive vehicle. A powered sliding door in an automotive vehicle, such as a van, moves along a predetermined path of travel between a closed position and a fully open position relative to the body of the vehicle. Such a sliding door may be provided with one or more electrically-operated actuators for performing functions associated with the door, such as power opening and closing the door, power unlatching the door, power locking and unlocking the door, and power clamping and unclamping the door in a soft or low-momentum manner. The invention is directed toward improved control systems and circuitry for operating such power-sliding door systems. One such control system employs a wireless communications link between the door and body, which is preferably implemented using radio frequency communication signals containing digitally encoded control signals. Control circuitry is preferably provided in the body and the door of the vehicle for supervising and carrying out the foregoing functions in an orderly manner in response to requests generated locally at the door or remotely by the driver from the console of the vehicle. A second, simpler, control system provides electrically-actuated mechanisms for unlatching the door and operating the door lock without the use of either a wireless communication system or a retractable electrical cable interconnecting the sliding door to the vehicle body.
Abstract:
A power window device in which a drive pulley around which a wire to open and close a window is wound is disposed within a case of a power window drive section and a wire guide for guiding the wire is mounted on the case. The wire guide is composed of a first wire guide for guiding one end of the wire and a second wire guide for guiding the other end of the wire. The second wire guide is removably coupled to the first wire guide. A wire guide angle .theta..sub.0 between the wire guides can be changed merely by exchanging the second wire guide. Even when a different wire guide angle is required, the size of the component to be replaced can be reduced, as can the cost to manufacture.

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 van door slidable in tracks (16, 18 and 20). An operating module is mounted inside the van adjacent center track 18. A front cable attached to drive pulley (144) extends through guide assembly (54) to hinge and roller assemble (26). A rear cable attached to drive pulley (136) extends through guide assembly (56) to hinge and roller assembly (26). The drive pulleys (136 and 144) each have a large diameter spiral cable groove (164), a small diameter cable groove (208) and a transition cable groove (210). A motor rotates the drive pulleys. The small diameter cable grooves drive the door when the door is in the forward portion of the tracks. The large diameter spiral cable grooves drive the door when the door is in the center and rear portions of the track. Fixed idler rollers (226 and 254) are positioned relative to the cable drive pulleys to insure that the total cable in the continuous cable loop is substantially the same when the cable is driven by the small diameter cable grooves as when the cable is driven by the large diameter spiral cable grooves. A cable tension system (220) maintains cable tension. A slack cable take-up pulley (174) on the drive pulley (136) takes up slack cable to set cable tension and is then locked in position.
