Abstract
A door latch assembly includes a housing, an inside and outside handle operably coupled with the housing, and a latch plunger. A latch cam is operably coupled with the inside and outside handles, and the latch cam further includes a crank arm slidably disposed against an inclined surface of an offset plunger leg operably coupled to the latch plunger. A biasing member urges the latch plunger to an extended position, wherein rotation of the inside or outside door latch handle in a first direction rotates the crank arm of the latch cam and displaces the plunger leg of the latch plunger and the latch plunger to a retracted position against the urging of the biasing member.
Claims27
A closable door latch assembly for an egress/ingress door pivotable between an open position and a closed position, the closable door latch assembly comprising:
- a first housing cover and a second housing cover in juxtaposed relation with one another to define a housing;
- a rotatable inside door latch handle operably coupled with the housing;
- a rotatable outside door latch handle operably coupled with the housing and the rotatable inside door latch handle;
- a latch plunger movable between an extended position and a retracted position, the latch plunger further comprising a plunger leg having an inclined surface;
- a latch cam operably coupled with each of the rotatable inside door latch handle and the rotatable outside door latch handle, the latch cam further comprising a crank arm slidably disposed against the inclined surface of the plunger leg;
- and
- a biasing member mounted within the housing urging the latch plunger to an extended position;
- wherein rotation of either of the rotatable inside door latch handle or the rotatable outside door latch handle in a first direction rotates the crank arm of the latch cam and displaces the plunger leg of the latch plunger and the latch plunger to the retracted position against the urging of the biasing member;
- and
- wherein the latch plunger comprises a main body received within an elongated recess disposed within the housing, and the latch plunger further comprises an offset portion upon which the plunger leg is mounted such that the plunger leg is disposed adjacent an interior surface of the first or second housing cover.
