Abstract
A locking mechanism is provided for an apparatus having a first member movable relative to a second member providing a plurality of spaced holes therein including: a housing secured to the first member; a lock pin extendably retractably mounted in the housing for insertion into the holes in the second member; and a powered control circuit having an actuated member movably mounted within the housing and connected to the lock pin, the actuator member providing differential force applying surfaces selectively exerting a predetermined locking force to hold the lock pin in the holes and a lower indexing force permitting substantially unrestricted relative movement between the first and second members and automatic insertion of the pin into one of the aligned holes.
