Digitally programmable protecting means and a key for mechanical rotary locking devices
First Claim
1. A digitally programmable protecting means and a key for a mechanical rotary locking device,said programmable protecting means comprising:
- a housing with a key way born rotatably in said housing and at least one communicating opening in said housing arranged from the outer surface of said housing to said key way for communicating to said key when said key is positioned in said key way;
a rotatable latchable means operationally attached to said housing at the end of said key way axially aligned with said key way, said rotatable latchable means having a key coupling cavity opened to said key way, rotatably aligned to said key way, an oblong strip attached to said rotatable latchable means for mechanical operating of said mechanical rotary locking device, said rotatable latchable means having at least one latching cavity designated to be engaged in mechanical latching action of said rotatable latchable means;
an electromechanical latching means, positioned adjacent to said rotatable latchable means, having a movable mechanical operational member insertable in said latching cavity of said rotatable latchable means for setting a latching state;
a key code sensing means, having a plurality of code bit sensing members, said code bit sensing members being exposed to said key way of said housing through said communicating opening in said housing for having direct contact with said key, positioned in said key way;
a key code decoding means communicably connected with said key code sensing means and with said electromechanical latching means for verification of the code received from said key code sensing means, and for operating of said electromechanical latching means reflective results of said key code verification;
said key comprising;
a central core with cross-sectional dimension smaller than diameter of said key way, said central core bearing a lock operating tip having shape and size matching said key coupling cavity of said rotatable latchable means for being freely inserted in said key coupling cavity, said central core having a guiding cylindrical hub positioned close to said lock operating tip, said cylindrical hub engaging in pressure contact with at least one said code bit sensing member of said key code sensing means, said cylindrical hub having diameter matching diameter of said key way of said housing for being freely inserted in said key way;
a plurality of cylindrical binary bit coding members having axially oriented openings matching the cross-sectional size and shape of said central core and having outer diameters not larger than diameter of said cylindrical hub, said bit coding members are put on said central core of said key for composing a binary code positioned along said central core;
a key handle fixedly attached to said central core on the opposite end of said lock operating tip for manual operation of said key.

Abstract
A digitally programmable protecting mechanism and a programmable key for a mechanical rotary lock for providing enhanced protection and enabling user to change mechanical and electronic security code configuration at any time without involving of special tools. The device includes a mechanical digitally configurable key where the protecting binary code configuration is formed by cylindrical binary coding members put on a central core of the key, and an electronic programmable digital module attached to a mechanical rotary lock for capturing the key code configuration, verifying, and releasing the lock if the verification proves that the key coding configuration and the electronic module coding are matched.
