Abstract

See full text

A door latch has an adjustable cam (25) to accommodate two backsets of the bore (24) through a door. The cam (25) is operably attached to a handle 14. Rotation of the handle (24) approximately 45.degree. fully retracts latch bolt (54) and deadbolt (56) through a slide actuator (100) that pulls a link (112) which pivots a cam lever (104) that retracts the bolt (54). The bolt (54) retracting motion is magnified with respect to the motion of actuator (100) via the link (112) and cam lever (104). The link (112) and cam lever (104) are mounted within cylinder section half (52) of housing (28) so as not to interfere with the deadbolt (56) and its slide (150) and deadbolt locking plate (170) that are mounted in a complementary cylinder half (51).
