Claims8
A latch device comprising in combination:
- a housing defining an interior and an opening at one end of said housing communicating with said interior;
- a latch element disposed in said housing interior and including a latch body and a latch head connected to said latch body, said latch element being linearly reciprocatably movable relative to said housing between an extended position wherein said head projects from said housing interior through said opening and a retracted position wherein said head is substantially completely retracted in said housing interior;
- means operatively associated with said latch element for moving said latch element from said extended position to said retracted position, said latch element having means including cam means rotatably mounted relative to said housing and adapted to be rotated by actuator means accessible outside said housing and a transmission arm pivotally mounted on said housing within said interior and having spaced first and second projections, said first projection engaging said cam means and said second projection engaging said latch element, said transmission arm pivoting in response to rotation of said cam means to effect linear movement of said latch element from said extended position to said retracted position, said cam means including two relatively movable cam elements disposed side-by-side within said housing, each said cam element including a lobe engageable with said first projection;
- and
- means for moving said transmission arm relative to the cam elements to cause selective engagement between the first projection and the lobes of either or both of said cam elements, said latch element being movable from said extended position to said retracted position only upon rotation of a cam element having the lobe thereof in engagement with said transmission arm first projection, said transmission arm moving means comprising a movable control member engageable with said transmission arm to move said transmission arm to a preselected one of a number of locations in said housing and manually engageable means operatively associated with said control member to effect manual movement of the control member and the transmission arm.

- means operatively associated with said latch element for moving said latch element from said extended position to said retracted position;
- a securement plate positioned on said housing adjacent to said housing opening;
- and
- means for attaching said securement plate to said housing, said housing defining a peripherally extending groove adjacent said opening thereof and said latch device further comprising a washer formed of resilient material disposed in said groove and engaging said securement plate when said securement plate is attached to said housing, said washer compressing to permit said securement plate to tilt relative to said housing to accommodate the bevel of a door.
