Abstract
A quick cam latch mechanism having an operatively coupled bolt and cam assembly disposed in a latch housing. A handle is coupled to the cam assembly for moving the bolt between an extended or engaged position and a retracted or disengaged position. The cam assembly includes a primary cam operatively coupled to a secondary cam or linkage that is in turn operatively coupled to the bolt. Rotation of the primary cam translates into increased pivoting of the linkage and thereby increased retraction of the bolt. As a result, less rotation of primary cam is needed to retract the bolt. In an example embodiment of the invention, at least two linkages are utilized to quickly retract the bolt regardless of the direction of rotation of the handle.
