Abstract

A lever latch, for releasably latching a door to a corresponding door frame, includes a housing having a handle pivotally mounted therein and rotatable between opened and closed positions. In the handle closed position, a bolt mounted to the handle engages the door frame, and in the handle opened position, the bolt is disengaged from the door frame. The housing includes a trigger pivotally mounted therein, and pivotable between a first position to retain the handle in the closed position and a second position to release the handle to the opened position. A pawl is rotatably mounted to a lock cylinder on the housing and rotatable between locked and unlocked positions to allow the trigger to pivot to the second position and to prevent the trigger from being pivoted to the second position, respectively.
