Compartment door latch

A compartment door latch for a closable compartment door having an outer perimeter comprising:

• a housing forming an interior chamber and mounted to the compartment door;
• a plunger mounted within the housing, the plunger having an extended position extending outside of the perimeter of the compartment door and a retracted position retracted within the perimeter of the compartment door, and a resilient member operably coupled with the plunger and urging the plunger to the extended position;
• a manually actuated exterior latch paddle handle mounted to an outer face of the housing, the exterior latch paddle handle having a closed position and an open position;
• a paddle cam operably coupled with the exterior latch paddle handle and extending into the interior chamber;
• a plunger cam operably coupled with the paddle cam and the plunger, whereupon actuation of the exterior latch paddle handle from the closed position to the open position displaces the paddle cam and actuates the plunger cam to displace the plunger from the extended position to the retracted position against the urging of the resilient member;
• and
• a lock bolt having a locked position and an unlocked position and adapted to prevent movement of the plunger in the locked position;
• a lock bolt driver disposed upon a lock bolt clutch operably coupled with a key lock and operably coupled with the lock bolt, wherein a lock bolt clutch and the lock bolt driver are rotatable between a first locked position and a second unlock position;
• and
• an electrically actuated motor and a motor actuator operably coupled with the lock bolt, and a controller for actuating the motor actuator, wherein the motor actuator is rotatable between a first locked position and a second unlock position;
• wherein the lock bolt is selectively displaceable between the locked position and the unlocked position by either of the key lock or the controller;
• and
• wherein the lock bolt further comprises a tab extending through a slot in a wafer spring and wherein the wafer spring has a first spring element that aligns with a first detent on an adjacent plate within the housing when the lock bolt is the locked position and the wafer spring has a second spring element that aligns with a second detent on the adjacent plate within the housing when the lock bolt is the unlocked position.

A compartment door latch for a closable compartment door having an outer perimeter comprising:

• an inner housing comprising a base plate having a base recess in an outer face thereof;
• an outer housing comprising a paddle recess in an outer face thereof, wherein the paddle recess is received within the base recess and an interior chamber is defined therebetween;
• a plunger mounted to one of the inner housing or outer housing, the plunger having an extended position extending outside of the perimeter of the compartment door and a retracted position retracted within the perimeter of the compartment door, and a resilient member operably coupled with the plunger and urging the plunger to the extended position
• a plunger actuator operably coupled with the plunger, the plunger actuator comprising a manually actuated exterior latch paddle handle rotatably mounted to the outer face and within the paddle recess of the outer housing, a paddle cam operably coupled with the exterior latch paddle handle, and a plunger cam rotatably mounting and operably coupled with the paddle cam and the plunger, whereupon actuation of the exterior latch paddle handle from a closed position to an open position displaces the paddle cam and rotates the plunger cam to displace the plunger from the extended position to the retracted position against the urging of the resilient member;
• a locking mechanism comprising a lock bolt having a locked position and an unlocked position, a lock bolt driver disposed on a lock bolt clutch and operably coupled with a key lock and operably coupled with the lock bolt, an electrically actuated motor and a motor actuator operably coupled with the lock bolt, and a controller for actuating the electrically actuated motor and motor actuator;
• a battery pack adapted to energize the electrically actuated motor mounted to the inner housing;
• a lock bolt stop disposed at a proximal end of the plunger that is engaged by the lock bolt when the lock bolt is displaced to the locked position or a lock bolt stop disposed on the paddle cam that is engaged by the lock bolt when the lock bolt is displaced to the locked position;
• a remote latch mount disposed on the plunger of the compartment door latch or a remote linkage cam mounted to the plunger cam, such that the remote linkage cam rotates simultaneously and in unison with the plunger cam;
• and
• one or more perimeter door latches disposed about an outer perimeter of the compartment door, wherein at least one of the plurality of perimeter door latches is operably coupled with the remote latch mount by a linkage;
• wherein the lock bolt is selectively displaceable between the locked position and the unlocked position by either of the key lock or the controller.
