Abstract
Abstract A door lock of the freewheeling type includes a locking lever movable between locked and unlocked positions to move the intermittent link between uncoupled and coupled positions. An abutment member carried by the locking lever is moved to an engaging position with respect to the detent when the locking lever is in locked position to thereby provide for automatic reconnecting. A set lever controlled by the outside operating means is operable to move the abutment member to a bypass position to provide keyless locking. Momentary actuation of the outside operating means is all that is required.

Claim 3
Dependent Claim
273 words
A closure latch comprising, in combination, latch means movable between latched and unlatched positions, detent means movable between detent and undetented positions with respect to the latch means and movable by the latch means in undetented position upon movement of the latch means from unlatched to latched position, movable operating means, coupling means operatively connected to the operating means for movement independently thereof between coupled and uncoupled positions with respect to the detent means and movement thereby in each position, movement of the coupling means in coupled position by the operating means moving the detent means to undetented position and releasing the latch means, locking means operatively connected to the coupling means for moving the coupling means between coupled and uncoupled positions with respect to the detent means upon movement of the locking means in unison therewith between unlocked and locked positions, movable abutment means mounted on the locking means for movement therewith from nonengaging to engaging positions with respect to the detent means in unison with movement of the coupling means from respective coupled to uncoupled positions, the abutment means being engageable in engaging position by the detent means upon movement of the detent means in undetented position by the latch means for movement of the abutment means from engaging to nonengaging position and movement of the locking means from locked to unlocked position to move the coupling means from uncoupled to coupled position, and means operative upon momentary operation of the operating means in the unlatched position of the latch means for moving the abutment means independently of the locking means to a bypass position with respect to the detent means.
Claim 4
Dependent Claim
273 words
A closure latch comprising, in combination, latch means movable between latched and unlatched positions, detent means movable between detent and undetented positions with respect to the latch means and movable by the latch means in undetented position upon movement of the latch means from unlatched to latched position, movable operating means, coupling means operatively connected to the operating means for movement independently thereof between coupled and uncoupled positions with respect to the detent means and movement thereby in each position, movement of the coupling means in coupled position by the operating means moving the detent means to undetented position and releasing the latch means, locking means operatively connected to the coupling means for moving the coupling means between coupled and uncoupled positions with respect to the detent means upon movement of the locking means in unison therewith between unlocked and locked positions, movable abutment means mounted on the locking means for movement therewith from nonengaging to engaging positions with respect to the detent means in unison with movement of the coupling means from respective coupled to uncoupled positions, the abutment means being engageable in engaging position by the detent means upon movement of the detent means in undetented position by the latch means for movement of the abutment means from engaging to nonengaging position and movement of the locking means from locked to unlocked position to move the coupling means from uncoupled to coupled position, and means operative upon momentary operation of the operating means in the unlatched position of the latch means for moving the abutment means independently of the locking means to a bypass position with respect to the detent means.
