Abstract:
An operator system for moving a barrier between limit positions, includes an operator motor assembly mounted to the barrier, wherein the motor assembly is movable between an operating position and a locking position with the motor assembly blocking movement of the barrier. A bias assembly allows the motor assembly to move toward the locking position when either a predetermined force overcomes a biasing force, or when the barrier is moved to a closed position or when forced entry is imposed on the barrier. A modified blocker tab having a plurality of projections, and which is part of the motor assembly, allows the speed/angular position of the rotation of the motor assembly to be monitored with increased resolution.
Abstract:
An operator for use in connection with a door system including an axle having an operator framework supporting an operator motor, the operator framework defining a clearance adapted to insertably receive the axle therein, a gear assembly defining a bore in which the axle is received and including a removable gear segment adapted to selectively medially open the bore to receive the axle, wherein the motor is interconnected with the gear assembly to cause rotation thereof.
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 system for moving a barrier between limit positions, includes an operator motor assembly mounted proximate to the barrier, wherein at least a portion of the motor assembly is movable between an operating position and a locking position with the motor assembly blocking movement of the barrier. A bias assembly biases the motor assembly in the operating position and allows the motor assembly to move toward the locking position when either a predetermined force overcomes a biasing force or when the barrier is moved to a closed limit position or when forced entry is imposed on the barrier. The biasing force may be adjusted by moving posts on the motor assembly that are engaged by the bias assembly. A disengagement feature may also be provided that allows pivotable movement of the motor assembly even when in a locking position. And the pivoting motor assembly may be used as a secondary entrapment input to an operator controller.
Abstract:
A system for raising and lowering a sectional overhead door between an open position and a closed position including, a counterbalance system adapted to be connected to the door, an operator motor assembly mounted proximate to the sectional overhead door in the closed position of the sectional overhead door, at least a portion of the operator motor assembly movable between a door operating position and a door locking position, and a locking assembly (370) having an engaged position to hold the motor assembly in the operating position and a disengaged position to release the motor assembly allowing it to move to the door locking position. The system may be provided with a remote light assembly having a switchable light source in sensing communication with the operator motor such that operation of the motor activates the light source. The system is further provided with a handle assembly (515) operatively engaging the motor assembly (40) and counterbalance system (30) to selectively disconnect the motor assembly (40) from the counterbalance system (30), whereby urging of a rotatable handle (516) to a disconnect position (516′) allows the door (D) to be manually freely moveable with the aid of the counterbalance system (30).

Abstract:
The invention relates to a motorized locking device for a door intended in particular for a rail vehicle, with at least one leaf. The device includes a tilting-body motor intended to be mounted on the vehicle. The axis of the motor is substantially parallel to the longitudinal direction of movement of the leaf.
Abstract:
An operator (10, 210) for moving in upward and downward directions a sectional door (D) having a counterbalancing system (30) including a drive tube (31) interconnected with the door comprising, a reversible motor (41), selectively driven in two directions by the motor, a driven gear (54) freely rotatably mounted on the drive tube and engaging the drive gear, a slide guide (56) non-rotatably mounted on the drive tube, a disconnect (70) mounted on the slide guide and selectively movable between a first position rotatably connecting the driven gear and the slide guide and a second position disconnecting the drive gear and the slide guide, and an actuator (80) for selectively moving the disconnect between the first position and the second position.
Abstract:
A sliding door operating mechanism for a vehicle to provide access to the vehicle through an opening in a wall thereof, includes at least one sliding door and reciprocating power means and transmission means for transmitting movement of the power means to the door for performing opening, closing and locking movements thereof. A beam structure carries the door, the power means and the transmission means. The beam structure extends across and is accommodated with an upper portion of the opening so as to be slidingly movably driven by the power means between a relatively retracted position within the opening, in which the door is located in a first plane in a closed position confined within the opening, and a relatively less retracted position, in which the door is located in a second plane exteriorly of the opening allowing movement of the door means along the second plane.
Abstract:
A method of aligning a door operating system for operating an upwardly acting door including an operator that directly interrelates with a counterbalance assembly in the door operating system to move the door, where the operator is at least partially supported on the counterbalance assembly, loosely attaching the operator to a header adjacent the door, and, moving the door from a closed position to an open position and returning the door to the closed position to achieve alignment. Once aligned, the operator is securely attached to the header to maintain the system's alignment.
