Abstract
The lock includes a latch member moveable between a retracted position where the truck door can be moved and an extended position where movement of the door is prevented. The latch member is moved by a reversible motor connected to drive a threaded screw through a set of speed reduction gears. An internally threaded drive nut is moveable along the screw. The drive nut has a radially extending protrusion which engages a slot formed in the latch member. Limit switches are tripped by the latch member at either end of its path of movement. The drive nut is situated between two springs. A control circuit is provided to regulate the energization of the motor and other functions of the lock.
