Abstract
Abstract An improved one-piece camera latch which may be formed from plastic or other moldable material and which includes a latching lug for releasably latching the cover member in a closed position, a resilient abutment member for urging the cover member to an open position when the latching lug is in a releasing position, and an end portion for moving a camera film-winding clutch member between an extended position when the latching lug is in a latching position and a retracted position when the latching lug is in a releasing position.

Claim 1
Independent Claim
233 words
A latch and release member for a camera, said camera including a housing having first and second abutment surfaces and a cover member having closed and open positions, said latch and release member comprising: a plate member mounted on the camera for movement between first and second positions; a latching lug movable with said plate member for engaging the cover member when the palate member is in its first position to latch the cover member in the closed position and for unlatching the cover member when the plate member is in its second position; a resiliently flexible arm having first and second opposed ends, said first end being connected to said plate member; and a release lug connected to the second end of said flexible arm, said release lug having: a. a cam surface for engaging the first abutment surface of said housing during movement of said plate member from its first to its second position, to first move said release lug in a direction stressing said resilient arm and then release said lug to permit said resilient arm to move said lug to engage the cover member and urge the cover member to an open position, and b. a plate member latching surface cooperable with said second abutment surface for latching said plate member in said second position as said release lug moves to urge said cover member to an open position.
Claim 2
Dependent Claim
