Abstract
Abstract A closure latch includes a ring member connecting the lock operating lever and slidably engaged over an angularly inclined portion of the rod connecting the inside remote handle and the latch operating lever. Initiation of actuation of the inside remote handle shifts the rod and causes the ring to be translated to move the locking lever from its locked position to its unlocked position. Continued actuating movement of the inside remote handle unlatches the door. Thus, the closure latch is unlocked and unlatched by a single actuation of the inside handle rather than by the sequential and separate lifting of a lock button followed by actuation of the inside handle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
90 words
A closure latch comprising in combination, a bolt movable between latched and unlatched positions, detent means for maintaining the bolt in the latched position, outside operating means, locking means incuding a locking lever for selectively coupling and uncoupling the outside operating means and the detent means, an inside operator, means coupling the inside operator to the outside operating means, and means interconnecting the inside operator and the locking means for operating the locking means to selectively couple the inside operator to the detent means upon operation of the inside operator.
Claim 2
Dependent Claim
90 words
A closure latch comprising in combination, a bolt movable between latched and unlatched positions, detent means for maintaining the bolt in the latched position, outside operating means, locking means incuding a locking lever for selectively coupling and uncoupling the outside operating means and the detent means, an inside operator, means coupling the inside operator to the outside operating means, and means interconnecting the inside operator and the locking means for operating the locking means to selectively couple the inside operator to the detent means upon operation of the inside operator.
Claim 3
Dependent Claim
119 words
A closure latch comprising in combination, a bolt movable between latched and unlatched positions, detent means for maintaining the bolt in the latched position, an operating lever, outside operating means actuable to operate the operating lever, an inside remote handle, a rod interconnecting the inside remote handle and the operating lever, locking means including a locking lever for selectively coupling and uncoupling the operating lever and the detent means, and means interconnecting the rod and the locking lever so that actuation of the inside remote handle sequentially operates the locking lever to couple the operating lever and detent and then operates the operating lever to move the detent means to a position releasing the bolt to the unlatched position.
Claim 4
Dependent Claim
119 words
A closure latch comprising in combination, a bolt movable between latched and unlatched positions, detent means for maintaining the bolt in the latched position, an operating lever, outside operating means actuable to operate the operating lever, an inside remote handle, a rod interconnecting the inside remote handle and the operating lever, locking means including a locking lever for selectively coupling and uncoupling the operating lever and the detent means, and means interconnecting the rod and the locking lever so that actuation of the inside remote handle sequentially operates the locking lever to couple the operating lever and detent and then operates the operating lever to move the detent means to a position releasing the bolt to the unlatched position.
Claim 5
Dependent Claim
191 words
A closure latch and lock therefor comprising in in combination, a bolt movable between latched and unlatched positions, detent means having a detenting position maintaining the bolt in the latched position and movable to an undetenting position permitting movement of the bolt to the unlatched position, an operating lever, an intermittent lever actuatable by the operating lever and movable between a position coupling the operating lever to the detent means and an uncoupling position uncoupling the operating lever from the detent, a locking lever operable to shift the intermittent lever between coupling and uncoupling positions, an inside remote handle, a rod interconnecting the inside remote handle and the operating lever for operating the operating lever upon actuation of the inside remote handle, a ring member connected to the locking lever and slidably engaging the rod whereby initiation of actuation of the inside remote handle translates the rod and operates the locking lever to couple the intermittent lever to the detent means so that the continued actuation of the inside remote handle operates the operating lever to move the detent means to its undetenting position releasing the bolt to the unreleased position.
Claim 6
Dependent Claim
191 words
