ABSTRACT:
A locking latch includes an outer housing and a handle in relative movable engagement with the outer housing. In rigid engagement with the handle is a barrel positioned in the outer housing. A key cylinder is in relative movable engagement with the barrel. The key cylinder is rotatable by a key between locked and unlocked positions in which rotation of the handle is, respectively, inhibited and enabled. A latching member is in movable engagement with the barrel so that rotation of the barrel by the handle induces movement of the latching member to latch and unlatch an access structure of a container. An engaging member is in movable engagement with the key cylinder so that rotation of the key cylinder induces movement of the engaging member between an engaged position where the handle is locked to the outer housing to inhibit rotation of the handle and an unengaged position where rotation of the handle is not inhibited.
