Electrical cylinder lock
View Patent ↗An electrical lock system comprises an electric motor, a remote control unit for authenticating authorized users prior to granting permission and communicating such information to a motor ( 5 ) driver circuitry wherein said motor ( 5 ) is built-in in a doorknob whose axis of rotation is arranged coaxial to said cylinder's longitudinal axis such that said motor's shaft extend along a cylinder adaptor region integrating said doorknob to said lock cylinder. Said adaptor portion is coupled to a mechanical bloc connecting said adaptor region to a battery bloc and to said motor ( 5 ) through an intermediary body integral to said doorknob enclosing said motor ( 5 ) and gear mechanism.
1. 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.
2. An electrical lock system as set forth in claim 1 wherein said gear mechanism is an eccentric gear comprising a stationary gear wheel and an eccentric gear wheel where a first orbiting cog wheel coupled to the main shaft engages with a secondary cog wheel in association with said motor's ( 5 ) shaft.
3. An electrical lock system as set forth in claim 1 or 2 wherein said motor ( 5 ) is responsive to the rotation of the main shaft such that it is automatically actuable thereupon.
4. An electrical lock system as set forth in claim 1 wherein both said cylinder ( 2 ) is equipped with a key slot for effecting unlocking by means of a key operable from the opposite side of said doorknob ( 7 ).
5. An electrical lock system as set forth in claim 4 wherein said battery bloc ( 10 ) is communicating with said motor ( 5 ) and an electronic control unit ( 8 ) through a conductive plate ( 9 ) enclosed in said intermediary body ( 6 ) integral to said doorknob ( 7 ).
6. An electrical lock system as set forth in claim 5 wherein said remote control unit ( 12 ) is a fingerprint reader module.
7. An electrical lock system as set forth in claim 6 wherein said remote control ( 12 ) unit is adapted to establish wireless communication with said motor ( 5 ) driver circuitry.
8. An electrical lock system as set forth in claim 1 wherein said lock cylinder ( 2 ) comprises a longitudinally extending cylindrical portion in the form of two divisions or cylindrical half-housings such that a first division of said lock cylinder ( 2 ) is mechanically operable without activating the motor ( 5 ).
