Abstract:
A mechanism and method for operating a track-mounted door is disclosed. The mechanism includes a pair of side drums that are connected by first cables to the bottom of the door. The side drums are coaxially mounted on a shaft for simultaneous rotation with a pair of cable drums. The cable drums are connected to high pressure gas struts by second cables. Each second cable is carried around a shiv wheel that slides along a guide track as the second cable moves. Each shiv wheel is operatively connected to one of the gas struts. As the shiv wheel moves along the guide track toward the cable drum, the gas strut is charged. As the shiv wheel moves away from the cable drum, the gas strut is discharged. A standard electric motor and screw driven lift-arm is used to initiate the opening and closing of the door. The charged gas strut stores sufficient energy to overcome friction and gravity to assist the electric motor and lift-arm to open the door.
Abstract:
An opening/closing apparatus for a vehicle, which has a door-lock mechanism, is provided. An output of a motor unit is transmitted to a drum having a planetary gear mechanism, and the slide door of the vehicle is driven by an open-side cable and a close-side cable wound around the drum. A closer cable of the door-lock mechanism is coupled to a carrier of the planetary gear mechanism, and coupled to a latch of the door-lock mechanism via a coupling link. The coupling link is constituted as a toggle mechanism so as to regulate the rotation of the latch by the traction force of the closer cable until the latch is rotated toward a full latch direction from an unlatch position. When the regulation of the latch by the toggle mechanism is released, the latch is rotationally driven toward the full latch direction due to the rotation of the carrier.
Abstract:
The present invention provides a cable guide for changing direction of an inner cable for operating a sliding door of a car, comprising a pulley casing having a box shape with an opening at its top and a guide recess at an inner side of its bottom, a slider provided with a sliding plate slidably guided by means of the guide recess of the pulley casing and a shaft extending upward from a top of the sliding plate, a pulley rotatably supported by the shaft of the slider, an urging member urging the slider along the guide recess toward a direction for giving tension to the inner cable, and a casing cover covering the opening of the pulley casing, and being configured so that an inner side of the casing cover and a top face of the shaft are slidable each other.
Abstract:
An improved apparatus and method for operating an auxiliary door is provided. Preferably, a remote signal, such as a radio signal, is used to initiate the opening of the door by a battery powered cable-retracting device or the like. The device is generally mounted on the wall adjacent to the door, but could also be mounted on the door. A cantilever extends out from the wall and door at the door hinge. A cable operated by a motor and pulley in the device is attached to the door such that when the motor is energized the door is opened to the cantilever overcoming the closing force for the door. This force is normally provided by a spring, hydraulic, pneumatic, or other known door closing device. Controls are provided to stop the opening motion if an obstacle blocks the door.
Abstract:
A barrier operating system having a diagnostic performance feature includes a motorized barrier movable between limit positions and a counterbalance system coupled to the barrier. A disconnect mechanism may be interposed between the motor and the counterbalance system so that the barrier can be moved manually without assistance from the motor. A position detection device is coupled to either the barrier or the counterbalance system and generates a barrier position signal. One of the motor and the position detection device generates operational parameter values for the barrier moving in either direction. A controller receives the operational parameter values and the barrier position signal, and as the barrier is manually moved, the controller compares operational parameter values for each direction of movement at a given position and generates a diagnostic signal based upon the comparison.
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 method and system for monitoring a movable partition. In one embodiment, the system includes a sensor linked to a movable partition, a drive system, and a controller. The drive system is configured to move the movable partition. The sensor, which in one embodiment includes a drum connected to the partition by a cable, is independent of the drive system. The sensor transmits a signal indicative of the rotational motion of the drum to the controller, which receives the transmitted signal and calculates at least one of a speed, acceleration, position, and direction of movement of the movable partition.
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 sealing plug for a block-and-tackle balance comprises a sealing member having an outer periphery shaped so as to conform to an inner surface of a channel of a window jamb in which the block-and-tackle balance is accommodated. An opening is defined in the sealing member allowing a cord of the block-and-tackle balance to pass therethrough such that the cord is movable with a movement of a window panel. A connector configuration in the sealing member and allows the sealing member to be releasably secured to a bottom end of the block-and-tackle balance.
Abstract:
An automatic opening/closing apparatus for vehicle including a detected subject and a detection sensor for detecting rotation of an output shaft is downsized. A worm gear mechanism decelerating a rotation speed of an electric motor to output it from the output shaft is accommodated in a gear case, and a drum is fixed to a tip portion of the output shaft projecting from the gear case to the outside, whereby motive power of the output shaft is transmitted from this drum to a sliding door. A concave portion centering at an axial center and recessed in an axial direction is formed in a worm wheel constituting the worm gear mechanism, a magnet unit constituting a rotation sensor is disposed inside the concave portion of the worm wheel, and a magnetic sensor for detecting rotation of the magnet unit is fixed to an inner surface of the gear case.
