Abstract:
A power window apparatus capable of opening a window or windows of a submerged automobile by manually operating a driver seat window open switch or a passenger seat window open switch both located on a driver seat window operation unit. The driver seat window operation unit and passenger seat window operation units have each a window close switch, a window open switch, a window open/close motor, and a motor drive controller. The driver seat window operation unit has a submersion detector for generating a submersion detection signal, a motor drive controller incorporating a control driver for opening windows when the driver manually operates corresponding window open switches, and connection lines for connecting normally close contacts of passenger seat window open switches located on the driver seat window operation unit with the normally close contacts of the window open switches located on the passenger seat window operation units.
Abstract:
A window lift mechanism for raising and lowering a window in a vehicle door includes a support bracket mounted to the window and a motor supported on the support bracket. A pair of parallel, vertical racks are mounted to the door and are positioned immediately adjacent the window. Pinion gears driven by the motor are supported on the support bracket and engaged with the rack to permit vertical movement of the window.
Abstract:
An open/close control system for a vehicle slide door includes in one embodiment, a drive source, e.g., a motor, a slide door opening/closing mechanism, a clutch for transmitting a drive force of the drive source to the opening/closing mechanism interruptively, movement signal generator for generating a signal dependent on the moving direction of the slide door, and slide door controller for controlling the drive force to be transmitted to the opening/closing mechanism by controlling the drive source and the clutch. The slide door controller stops the operation of the drive source and thereby stops the slide door, declutches the clutch to allow the slide door to be movable, detects a movement of the slide door caused by its weight by use of an output signal of the movement signal generator, and determines an inclination of the vehicle on the basis of the detection result.
Abstract:
A device for automatically controlling the operation of a sliding door for a vehicle, the sliding door being mounted on a side of the vehicle body so as to automatically be operated by a driving source such as a motor and freedom and safety incompatible with each other being able to be controlled, the device comprising a door driving portion having a motor rotatable in forward and reverse directions, motor load detector for detecting the load of the motor, door position detector for detecting a door position within a range from a fully opened position to a fully closed position, door speed detection for detecting the travelling speed of the door, a storage device storing the load of the motor when the vehicle body is in a normal posture as a specific load of the motor associated with the position of the door by correlating the motor detector with the door position detector and motor controller for controlling electric power supplied to the motor while detecting a motor speed, by a deviation between a motor load stored for a specific door position and a motor load for driving the door at that position.
Abstract:
A locking system (10, 110, 210) for a sectional overhead door (11) powered through a counterbalance system (30) including, a flexible member (C) interconnecting the counterbalance system and the door and providing tensioning during opening and closing of the door, a movable stop (50, 150, 250) selectively actuatable to a locked position precluding movement of the door, and a biasing member (65, 165, 255) urging the movable stop toward the locked position, whereby in the event of slack in the flexible member the biasing member displaces the movable stop to the locked position.
Abstract:
A power door for a transit vehicle includes a door panel, a base and hanger unit, a door support, a drive member and a motor. The door support is attached to the door panel and includes at least one roller which engages a hanger portion of the base and hanger unit for motion along the base and hanger unit. The hanger portion includes a longitudinal cavity and a slot communicating with the cavity. The drive member is disposed within the cavity and a drive member connector passes through the slot to connect the drive member to the door support.
Abstract:
An automatic door operator for swing doors which uses a worm gear transmission to connect the motor to a belt and pulley which in turn is connected to a spur gear and drive gear. The door arm of the swing door is connected to a double-ended shaft which is part of the drive gear. A rack and pinion gear and spring are used to provide the closing force to the door arm. The motor is mounted over the spring and the belt and pulleys are located alongside the motor which results in a compact non-handed design.
Abstract:
A drive apparatus, in particular for the automatic actuation of a sliding door of a motor vehicle, comprising a fast running motor, the motor shaft of which is connected to a transmission with a large step-down ratio, the transmission having a first gear wheel which can be secured against rotation, via a releasable blocking device, and a second rotatable gear wheel which is rotationally fixedly connected to an output drive shaft and which is rotatable relative to the first gear wheel by the rotation of the motor when the first gear wheel is blocked, with the number of teeth of the first gear wheel only differing by a few teeth from the number of teeth of the second gear wheel and with the large step-down ratio being determined by this difference of the tooth numbers. By releasing the blocking device, the step-down ratio of the transmission changes. In particular a step-down ratio of 1:1 results. The transmission is thereby capable of being driven in reverse, so that a manual actuation of the sliding door of a motor vehicle is possible, without the requirement for a releasable clutch device between the sliding door and the drive apparatus.
Abstract:
A power operating system for opening and closing a vehicle liftgate has a pair of drive units supported on the vehicle roof and connected to the liftgate for opening and closing the liftgate. Each drive unit includes a bracket that is secured to the vehicle body for supporting several parts including a reversible electric motor, a gear unit and a track. The electric motor drives a segmented sector inside the track via a gear reduction unit. The segmented sector includes an arcuate link that slides in an arcuate track portion of the track and a plurality of short sector links that are stored in a storage track portion when the liftgate is closed. The arcuate link has an outboard end that is pivotally connected to the liftgate to open and close the liftgate as the arcuate link is extended and retracted by the segmented rack.
Abstract:
A method of programming a controller for a movable barrier operator includes enabling and disabling an input device within a predetermined period of time, a predetermined number of times. This sequence of short activations of an input device, such as a switch on a wall unit, puts the controller in a learn mode or a programmed state. Thereafter, the controller is responsive to learn any of the various routines that can be programmed for the movable barrier operator, such as transmitter code, limits of travel, force settings, and so on.
