Mortise lock apparatus and electronic operating system

摘要

The disclosure describes a locking system for a door with a mortise pocket. The locking system has a mortise case within the mortise pocket. The mortise case defines an alignment hole. The locking system also has a gear box with a worm gear that defines a notched passage that receives a lock knob shaft. A worm within the gear box is coupled to a motor that rotates the worm. The worm engages the worm gear such that the worm gear rotates when the worm rotates. A control board in the gear box is adapted to receive electronic signals and transmit them to the motor to cause the motor to rotate the worm. The gear box also has a worm gear hub that defines a keyed passage and a hub tab. The worm gear hub fits within the notched passage and the keyed passage receives the lock knob shaft. The worm gear also has two notches that the hub tab contacts individually when the gear hub rotates within the notched passage.

主权项

1. A locking system for a door including a mortise pocket and a centerline, the locking system comprising:
a mortise case adapted for disposal within the mortise pocket, the mortise case defining an alignment hole; an inner escutcheon adapted for disposal on one side of the door adjacent the mortise pocket; an outer escutcheon adapted for disposal on another side of the door adjacent the mortise pocket; a pin adapted for fastening substantially perpendicularly to one side of the inner escutcheon and including an angled cam channel, wherein the pin is shaped to enter the mortise case through the alignment hole such that the angled cam channel is disposed inside the mortise case; and a mortise case screw adapted for disposal within the mortise case substantially perpendicular to the pin, wherein one end of the mortise case screw is adapted to engage the angled cam channel and pull the inner escutcheon toward the centerline of the door, without pulling the outer escutcheon towards the centerline of the door, as the mortise case screw is tightened.
