Door lock and operation mechanism
First Claim
1. A programmable biometric door locking apparatus comprising:
- a door operation device comprising;
a door handle a and a door handle support body defining a rotational axis about which the door handle rotates relative to the support body;
a bolt having a locked and an unlocked state as controlled by a locking mechanism;
an operating rod extending along the rotational axis of the door handle to connect the bolt and the door handle;
an electronic user verification system comprising;
a first input having a non-optical biometric fingerprint scanning surface aligned on an outer surface of the door handle perpendicular and coaxial about the axis of rotation of the door handle or receiving input data from direct contact with a user'"'"'s fingerprint;
a memory for storing comparison data;
a processor for comparing received input data with the stored comparison data and producing an output instruction to the locking mechanism to place the bolt in the looked or the unlocked state; and
a second input positioned on the door handle support body apart from the first input to facilitate the storage of comparison data in the memory.

Abstract
A locking doorknob 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 electro-mechanical device which can be powered by a remote electrical power system, specifically by electromagnetic induction through the door latch and strike plate. During operation, as soon as a user grasps the doorknob, a fingerprint is measured and searched, 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.
