ABSTRACT:
A door handle assembly including an escutcheon plate, a handle secured to the outer face of the escutcheon plate, and a turn lever mounted on the outer face of the escutcheon plate. The turn lever includes an actuator portion which passes through a transverse slot in the escutcheon plate and through an actuator hole in the door for access to the actuator of a latch assembly so as to move the latch assembly between latched and unlatched positions in response to turning of the turn lever. The actuator portion of the turn lever may be moved laterally within the slot in the escutcheon plate to accommodate door installations in which the actuator hole is centered with respect to the mounting holes for the escutcheon plate as well as installations in which the actuator hole is offset with respect to the mounting holes and the lever portion of the turn lever acts in both installations, and in all positions of the actuator portion of the turn lever, to completely mask the slot so as to preserve a pleasing exterior appearance for the door assembly. The slot also allows the same door assembly to be used for either right handed or left handed installations. The slot is provided offset with respect to the longitudinal midpoint of the escutcheon plate so as to accommodate the vast majority of door installations and a further slot is provided on the midpoint of the escutcheon plate to accommodate those installations where the actuator hole in the door is centered with respect to the mounting holes in the door.
