Holding coil for electronic lock
First Claim
1. An electronic lock, the electronic lock comprising:
- a locking mechanism comprising a bolt and extensions coupled with the bolt;
a cartridge comprising a body portion and extension receiving portions, the extension receiving portions configured to receive the extensions of the locking mechanism;
a first coil positioned around the cartridge;
a core disposed within the cartridge and substantially within the first coil;
a first sliding barrier disposed within the cartridge and comprising a first magnetic material, the first sliding barrier selectively in communication with one or more of the extensions of the locking mechanism, the first sliding barrier being located on a first side of the core and being magnetically attracted to the core;
a second sliding barrier disposed within the cartridge and comprising a second magnetic material, the second sliding barrier selectively in communication with one or more of the extensions of the locking mechanism, the second sliding barrier being located on a second side of the core and being magnetically attracted to the core;
a second coil positioned around the cartridge, the second coil being spaced from the first coil and being positioned on the first side of the core;
a third coil positioned around the cartridge, the third coil being spaced from the first coil and being positioned on the second side of the core; and
a control circuit in communication with the first, second, and third coils, the control circuit operative to;
energize the first coil to create a magnetic field in the core, the magnetic field causing the first and second sliding barriers to move away from the core, andenergize the second and third coils after a predetermined time has elapsed, such that the first sliding barrier is magnetically attracted to the second coil and the second sliding barrier is magnetically attracted to the third coil, thereby allowing actuation of the locking mechanism.

Abstract
An electronic lock may include a locking mechanism and a cartridge having a body portion and one or more extension receiving portions that may receive the locking mechanism. The lock may also include a first coil positioned around the cartridge, a core disposed within the cartridge and substantially within the first coil, and a second coil positioned around the cartridge. The second coil may be spaced from the first coil. In addition, a first sliding barrier may be disposed within the cartridge, which barrier may be selectively in communication with the locking mechanism. A control circuit may be included in the lock, which may energize the first and second coils to cause the first sliding barrier to move from a first position magnetically attracted to the core to a second position magnetically attracted to the second coil and thereby allow actuation of the locking mechanism.

15. A method of actuating an electronic lock, the method comprising:
-
energizing a first coil positioned around a cartridge of a lock assembly to generate a first magnetic field within the cartridge; using the first magnetic field to repel a barrier slidably disposed within the cartridge and in communication with a locking mechanism, said repelling causing the barrier to move from the first coil toward a second coil positioned around the cartridge; energizing the second coil to generate a second magnetic field in the coil; and using the second magnetic field to attract the barrier to the second coil, such that the barrier moves away from the locking mechanism and thereby allows movement of the locking mechanism. - View Dependent Claims (16, 17, 18, 19, 20)
