Abstract
A cylinder lock insert 10 has a manually operable knob 14 which is used to operate a lock bolt 6 of a rim lock 8 or the like. The knob 14 substantially encloses a lock input means 30 which is preferably a finger or thumb print recognition device. Correct user input causes a controller to engage a solenoid operated clutch 16 which in turn allows torque from the manual turning of knob 14 to be transmitted to the mechanism of the bolt 6. The lock may be rechargeable by means of a solar cell 34 and/or a knob operated dynamo (74 FIG. 4).
Claims20
A cylinder insert for use in a cylinder lock of the type comprising a housing for attachment to a structure and including a bolt or latch operably moveable from a closed to an open position, said cylinder insert comprising:—
- a user input device for receiving unlocking information from the user;
- a controller for determining the validity of the user input;
- a manually rotatable unlocking knob for operating said bolt or latch, the knob extending substantially peripherally around the input device;
- and
- a drive rotatable about an axis, for driveably connecting the knob to the bolt or latch, and for transmitting rotation of the knob in use to the cylinder lock along said axis to cause said bolt or latch to move from its locking position to its unlocking position, the drive including a coupling, said coupling being responsive to said controller to selectively engage said drive to allow transmission of said rotation to said cylinder lock along said axis when said controller determines valid user input.
An electrically operable lock or lock insert, including a manually rotatable part for causing locking or unlocking action of the lock, the manually rotatable part being in driving communication with a dynamo for producing current when the manually operable part is rotated.
