    Abstract: An improved garage door operator of the motor-driven chain-and-sprocket type comprising a molded plastic gear case assembly supporting an output shaft for rotation relative thereto. A molded plastic worm wheel is loosely disposed on the shaft for limited rotation relative thereto and is driven by a reversible electric motor through a worm. Camming surfaces on the worm wheel and a second element which is fixedly disposed on the shaft form a low-torque coupling such that under normal conditions the motor drives the shaft to move the garage door. If the door encounters an obstacle and is unable to move, continued rotation of the motor drives the cam surface of the second element up the cam surface of the wheel so as to axially shift the second element relative to the gear case to trip a reversing switch. Up and down limits are established by means of a small threaded shaft which is driven off of the worm wheel and which produces linear displacement of a limit switch actuator traveler. The traveler carries adjustable dogs which operate respective limit switches in a limit switch carrier which is mounted on the gear case.

    Abstract: A locking device for securing a motor vehicle component which is displaceable relative to a motor vehicle structure and which may be secured by means of the locking device within a displacement range in a respective position of rest reached by displacement is provided. The locking device comprising at least one first frictional element and at least one second frictional element, which is moved relative to the first frictional element upon displacement of the motor vehicle component and thereby may slide with a friction surface along a friction surface of the first frictional element under sliding friction conditions and which, in a respective position of rest of the motor vehicle component, with its friction surface bears against the friction surface of the second frictional element under static friction conditions. A flowable additional medium is provided which may be brought, upon a relative movement of the frictional elements, between their friction surfaces.
