Abstract: A lock structure for mounting between first and second supporting surfaces including a cup mounted on the first surface, a housing mounted on the cup, a rocker arm located within the housing and pivotally mounted on the cup, a keeper mounted on the second supporting surface, interengaging surfaces between the rocker arm and the keeper for effecting a locking relationship therebetween, a spring located between the housing and the rocker arm to bias the rocker arm in a locking position relative to the keeper, and an actuator shaft keyed to the rocker arm and rotatably mounted in the housing and having a curvilinear groove therein for receiving a mating key for pivoting the actuator shaft and the rocker arm keyed thereto out of locking engagement with the keeper.
Abstract: A latch/ejector mechanism (2), designed for use with components (6) such as power supplies, computer modules and circuit boards, is used to secure a component to and release the component from a housing (104) by engaging and disengaging a catch element (96) on the housing. The mechanism includes a handle (8) pivotally mounted to the component for moving between latched and unlatched positions. The handle has a latch (94) at one end (28) which engages with and disengages from the catch element during such pivotal movement of the handle. The mechanism also includes a trigger (10) which must be actuated to permit the handle to be moved from the latched position to the unlatched position. A security lock (12), movable between locked and unlocked positions, is used to prevent the actuation of the trigger. In the locked position the lock surface (86) of the security lock opposes a portion of the trigger, called a prevent element (90).
