Abstract
An electronic access control device with an actuator that requires little energy to change between the coupled and decoupled states. The actuator can have levers that interact to bias the control actuator in the decoupled state. The actuator can be changed between coupled and decoupled states by magnetizing and demagnetizing an armature that interacts with the levers. The electronic lock can include a security apparatus that prohibits the electronic lock from changing between the coupled and decoupled states when an external magnetic field is applied.
Claims13
An electronic access control device for a lock to secure a closure panel, the lock including a latch, a force transfer member and a coupling apparatus, the coupling apparatus coupling the force transfer member to the latch in a coupled state, the force transfer member not coupled to the latch in the decoupled state, the electronic access control device comprising:
- an authenticator circuit;
- and
- an actuator comprising an actuator lever, an armature and a coil;
- wherein the authenticator circuit provides an electrical current to the coil to magnetize and demagnetize the armature to place the actuator lever in the coupled state and decoupled state, respectively;
- and
- wherein the electrical current is provided to the coil only to change between the coupled and decoupled states.
An electronic access control device for a lock to secure a closure panel, the lock including a latch and a force transfer member, the electronic access control device comprising:
- a coupling apparatus including a blocking member, the coupling apparatus coupling the force transfer member to the latch in a coupled state when the blocking member is in a coupled position, the force transfer member not coupled to the latch in a decoupled state when the blocking member is in a decoupled position, the blocking member biased to the coupled position by a blocking spring;
- an authenticator circuit;
- and
- an actuator including an actuator lever biased by a lever spring to push the blocking member into the decoupled position;
- wherein the lever spring overcomes the blocking spring in the decoupled state.
