Abstract:
An operator system for moving a barrier between limit positions, comprising an operator motor assembly mounted proximate to the barrier, at least a portion of said operator motor assembly movable depending upon an operating condition thereof; a counterbalance system adapted to be connected to the barrier, said counterbalance system coupled to said operator motor assembly to move the barrier; and an integral cable storage drum and transfer assembly connecting said operator motor assembly to said counterbalance system.
Abstract:
A unit support for a motor vehicle door includes at least one longitudinally extended guide rail of a motor vehicle window lifter arranged on the unit support, which extends between a first and a second end portion and on which a drive element serving to receive a window pane to be adjusted along an adjusting path of the guide rail defined by guide surfaces is movably guided. A hollow body is integrally formed on the unit support in the region of at least one end portion of the guide rail. The hollow body extends the guide surfaces of the guide rail serving to guide the drive element, defining the adjusting path and/or a deflection element is provided on the hollow body for deflecting a flexible traction means of the window lifter, in order to increase the length of travel of the motor vehicle window lifter in the direction of extension of the guide rail.
Abstract:
Brackets for interrupting the opening of a multi-panel garage door and methods for their use, the brackets including a first plate having an inner face and an outer face, a pin located on the outer face of the first plate, and a protrusion associated with the first plate, the protrusion and pin defining a gap capable of accepting a garage door opening cable.
Abstract:
A vehicle door articulating and sliding mechanism is provided that includes a swing arm pivotally mounted via a first bracket to a vehicle structure at one end and a sliding assembly comprising a rotating second bracket mounted at an opposite end of the swing arm. The sliding assembly is slidably engaged to a vehicle door. The mechanism also includes a first flexible link at least partially encircling a first sprocket connected to the vehicle structure and a second sprocket fixed to the vehicle door. The mechanism further includes a second flexible link fixed to the vehicle door at one end and fixed to the vehicle structure at the opposite end. The second flexible link at least partially encircles a cam, wherein the first flexible link and cam provide a catch that engages the cam to accelerate movement of the door during opening.
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:
A drive unit is arranged in a side of one side surface of a panel constituting a part of a door, and a drum case of a driven unit is fixed to a side of another side surface of the panel. The side of another side surface of the panel is provided with a plurality of engagement portions, which are engaged respectively with a plurality of to be engaged portions provided in the drum case, thereby positioning the drum case.
Abstract:
A drive unit for a power operated vehicle closure has a track, a guide moveable along the track, a link attached to the guide at one end and adapted to be attached to the vehicle closure at the opposite end, and a motor assembly for moving the guide along the track. The motor assembly has an electric motor and a speed reducer driven by the electric motor that has a first stage and a second stage. The first stage includes a belt drive and the second stage is a spur gear set. Alternatively the first stage is a worm gear and a mating helical gear. The worm gear preferably has a high lead angle and a high number of leads. The speed of the electric motor is reduced to about 1000 rpm or less in the first stage permitting the use of spur gears in the second stage while retaining quiet operation.
Abstract:
The present disclose a support structure with torque transfer function, comprising a link member, whose bottom and top portions have an upper end and a lower end, respectively; a pair of main supports oppositely and perpendicularly disposed at the surface of the base member and are pivoted to the lower end of the link member through an intermediate hinges, such that the link member is rotatably pivoted between the two main brackets; a base member having a pair of oppositely and perpendicularly arranged auxiliary brackets disposed at one side of the pair of main brackets, a base hinge pivoted between the pair of main brackets and the pair of auxiliary brackets, and a base hinge socketingly connected to a resilient support and disposed between the main brackets and the auxiliary brackets, respectively, having one end passing through the auxiliary bracket and socketingly connected to a linkage part and the other end passing the main bracket; and a torque transfer device having upper and lower rotation parts pivoted to the intermediate hinge and the base hinge so as to move synchronously together and a connecting part linking the upper and lower rotation parts to rotate in the same direction, thereby forming a torque transmission path.
Abstract:
Under a method to control a sliding speed in accordance with this invention, the motor is initially accelerated for a predetermined reference speed, and then during the initial acceleration period, if a rotational speed of the wire drum is of and above a given value, a difference between a rotational speed of the wire drum and a rotational speed of the motor is of and above a given value, and a rate of acceleration of the wire drum is of and above a given value, the rotational speed of the motor is reduced temporarily judging the slide door is in a state of abnormal acceleration, and then the motor is accelerated again at a lower rate than the initial acceleration toward the reference speed.
Abstract:
An automatic closing device for returning a sliding section of a sliding door assembly to a closed position without application of an external force. The automatic closing device has a controlled return mechanism that has an adjustable mass assembly and a spring. The controlled return mechanism generates a force that returns the sliding section to its closed position after the sliding section is opened. The controlled return mechanism has a connector having a first end and a second end. The first end of the connector is attached to a fixed position on the sliding door assembly and the second end of the connector is attached to a top end of the controlled return mechanism. The controlled return mechanism has a pulley assembly having a plurality of pulleys that guides the connector from the top end of the controlled return mechanism to the fixed position on the sliding door assembly.
