Abstract
Abstract A door lock includes a main frame having spaced side flanges. An operating lever is intermediately pivoted to the main frame between the side flanges, and the arms of the lever are respectively connected to the inside remote handle and outside release handle. The lever further includes a laterally extending arm to which is pivoted one end of an intermittent member having a laterally extending tab at the free end thereof. A locking lever is pivoted to the side flanges of the frame for movement between locked and unlocked positions and is located in each position by the cooperative action of an overcenter type torsion spring and the engagement of shoulders of the lever with a tab of the frame. The locking lever includes an arcuate slot in which is received the tab of the intermittent member. An inverted fork bolt is mounted on the frame for movement between latched and unlatched positions and a detent for the bolt is also pivoted to the main frame and includes a lateral arm. The locking lever slot in the unlocked position of such lever proscribes a path about the detent pivot. Movement of the operating lever when the locking lever is in unlocked position bodily shifts the intermittent member and engages the intermittent member tab with the detent arm to release the detent When the locking lever is in locked position, the slot thereof pivots the intermittent lever about the operating lever so that the intermittent member tab bypasses the detent arm.

Claim 1
Independent Claim
200 words
A closure latch comprising, in combination, latch means movable between latched and unlatched positions, a detent swingable between detented and undetented positions with respect to the latch means and including an engageable portion, a locking lever swingable about an axis transverse of the detent axis between locked and unlocked positions and including a slot therein generally following a path proscribed about the detent axis when the locking lever is in unlocked position, a swingable operating lever adapted to be connected to inside and outside release means, and an intermittent member swingably supported by the operating lever for translation thereby and swinging movement relative thereto, the intermittent member including a portion received within the slot of the locking lever and located in the path of movement of the engageable portion of the detent when the locking lever is in unlocked position, the slot in the locking lever guiding the portion of the intermittent member along such path upon translation of the intermittent member by the operating lever to thereby swing the intermittent member relative to the operating lever and ensuRe engagement of the intermittent member portion with the detent engageable portion and movement of the detent between detented and undetented positions.
Claim 2
Dependent Claim
200 words
A closure latch comprising, in combination, latch means movable between latched and unlatched positions, a detent swingable between detented and undetented positions with respect to the latch means and including an engageable portion, a locking lever swingable about an axis transverse of the detent axis between locked and unlocked positions and including a slot therein generally following a path proscribed about the detent axis when the locking lever is in unlocked position, a swingable operating lever adapted to be connected to inside and outside release means, and an intermittent member swingably supported by the operating lever for translation thereby and swinging movement relative thereto, the intermittent member including a portion received within the slot of the locking lever and located in the path of movement of the engageable portion of the detent when the locking lever is in unlocked position, the slot in the locking lever guiding the portion of the intermittent member along such path upon translation of the intermittent member by the operating lever to thereby swing the intermittent member relative to the operating lever and ensuRe engagement of the intermittent member portion with the detent engageable portion and movement of the detent between detented and undetented positions.
Claim 3
Dependent Claim
