ABSTRACT:
In a door lock having a latch bolt selectively retractable by a rotatable driver spindle, the driver spindle being rotatable by operation of an outside manual lever associated with an outside chassis assembly or by operation of an inside manual lever associated with an inside chassis assembly, a lost motion mechanism is provided between the driver spindle and the inside chassis assembly so that rotational movement of the driver spindle is not transmitted to the inside lever. An interconnect mechanism connects the inside lever to a deadbolt operating assembly whereby operation of the inside lever retracts both the latch bolt and the deadbolt. The lost motion mechanism includes a driven spindle located within an axially extending bore in a spindle core and having an opening for receiving an end of the driver spindle, the spindle core being mechanically linked to the inside lever. The driven spindle and core are configured such that rotational movement of the spindle core is transmitted to the driver spindle but rotational movement of the driver spindle and driven spindle is not transmitted to the spindle core. The interconnect mechanism includes a lower cam driven by the spindle core for moving a slide plate, and an upper cam mounted on an operating bar which is rotated to retract or extend the deadbolt. As the lower cam is rotated, it moves the slide plate which is configured to receive and rotate the upper cam so that the operating bar retracts the deadbolt.
