Abstract
A locking device for a mobile filing and storage system comprises a reciprocable pin disposed in a rotatable handwheel. The pin is adapted to selectively engage or disengage locking apertures in a stationary plate mounted to the storage frame. The pin is formed with a pair of symmetrical frusto-conical surfaces having apexes that blend into concave surfaces that receive biasing means to retain the pin in the selected engaged or disengaged position against accidental reciprocation of the pin and to provide a tactile feel of proper location in and displacement from the engaged or disengaged position.
