An object detection system for use in detecting the presence of an object within a space, such as in an aisle of a mobile storage system bounded by at least one mobile storage unit, includes a pair of pivotable light emitter/receiver unit located outwardly of each side of the space and a series of reflectors located outwardly of each side of the space. Each emitter/receiver unit includes a pivotable emitter which emits a beam of light which passes across and through the space and impinges upon the reflectors located outwardly of the opposite side of the space. A receiver associated with each emitter/receiver unit receives reflected light from the reflectors. The presence of an object within the space prevents the light beam from reaching one or more of the reflectors, and the absence of one or more reflected light beams is detected such that operation of the mobile storage unit is prevented until the object exits or is removed from the space.

Rotating light source system for detecting an obstruction in a space, for use in a mobile storage system

A rotary storage unit includes a cabinet defining an interior within which a rotary storage member is located. A latch mechanism is mounted to the cabinet, and selectively engages the rotary storage member for maintaining the storage member in either an open position or a closed position. A motorized actuator arrangement is interconnected with the latch mechanism, for selectively moving the latch mechanism between a latching position and a release position. The motorized actuator arrangement includes a motor which imparts movement to an actuator rod interconnected with the latch mechanism, for moving the latch mechanism between its latching and release positions in response to axial movement of the actuator rod. The motor moves the actuator rod so as to return the latch mechanism to its latching position after expiration of a predetermined time delay. The actuator rod is interconnected with a spring which biases the latch mechanism toward its latching position, to provide a positive stop when the storage member is moved to a predetermined position relative to the cabinet. The motorized actuator arrangement is operable in response to operation of a hand-operable switch mounted to the cabinet.
