Door lock and operation mechanism
First Claim
1. A door locking apparatus comprising:
- a user verification system for receiving input data from the user comprising;
a memory for storing comparison data;
a processor for comparing received input data with the stored comparison data and producing an output instruction;
a controller for actuating a switch according to the output instruction;
a locking and unlocking mechanism controlled according to the actuation of the switch, the locking and unlocking mechanism comprising;
a gear, immovably retained against rotation around an axis by a fixed sleeve defining a locked state of the door locking apparatus, and an unlocked state of the door locking apparatus defined by axial displacement of the gear along the axis and out of engagement with the fixed sleeve; and
a bolt mechanism connected to the locking and unlocking mechanism for causing relative movement of a bolt between an extended and retracted positions.

Abstract
A locking doorknob which recognizes a fingerprint in which the detecting sensor of a fingerprint is installed on the spot of the doorknob that a thumb or other fingers are placed naturally as the door is being opened. The locking doorknob is an electromechanical device which can be powered by a remote electrical power system, specifically by electromagnetic induction through the door latch and strike plate. During operation, a fingerprint is measured and searched as soon as a user grasps the doorknob and, if the fingerprint corresponds to a fingerprint previously input, the door is unlocked and the doorknob can be turned to open the door. In this way, fingerprint recognition and opening of the door are performed at the same time.
