Patent ID: 8689594

Claim:
An electrical lock system comprising an electric motor, a remote control unit ( 12 ) for authenticating authorized users prior to granting permission and communicating such information to a motor ( 5 ) driver circuitry upon which said motor ( 5 ) automatically effects locking and unlocking by way of rotation of a shaft, said system further comprising a lock cylinder ( 2 ), wherein said motor ( 5 ) is built-in in a doorknob ( 7 ) whose axis of rotation is arranged coaxial to said cylinder's ( 2 ) longitudinal axis such that said motor's shaft extend along a cylinder adaptor region ( 3 ) integrating said doorknob ( 7 ) to said lock cylinder ( 11 ), said cylinder adaptor region ( 3 ) is coupled to a mechanical bloc ( 4 ) connecting said cylinder adaptor region ( 3 ) to a battery bloc ( 10 ) and to said motor ( 5 ) through an intermediary body ( 6 ) integral to said doorknob ( 7 ) enclosing said motor ( 5 ) and a gear mechanism, said gear mechanism couples said motor's ( 5 ) shaft to a shaft being coaxial with the doorknob ( 7 ) longitudinal axis, said main shaft is eccentric to said motor's ( 5 ) shaft, shaft of said cylinder ( 2 ) is directly rotatable by said motor ( 3 ) through said gear mechanism while said doorknob ( 7 ) maintains its stationary position.
