Abstract

An electric strike for a door frame, comprising: a body; a keeper moveably attached to the body for selectively 5 retaining a latch bolt on a door; a blocking element movable between a blocking position in which the blocking element locks the keeper to prevent a latch from being moved past the keeper, and an unblocking position in which the blocking element unlocks the keeper to allow the latch 10 to move past the keeper; an electronically controlled electric actuator for moving the blocking element between the blocking position and the unblocking position; and an override mechanism to override the electric actuator.

Claims

1. An electric strike for a door frame, comprising:

a body;

a keeper moveably attached to the body for selectively retaining a latch bolt on a door;

a blocking element movable between a blocking position in which the blocking element locks the keeper to prevent a latch from being moved past the keeper, and an unblocking position in which the blocking element unlocks the keeper to allow the latch to move past the keeper;

an electronically controlled electric actuator for moving the blocking element between the blocking position and the unblocking position; and

an override mechanism to override the electric actuator.

2. The electric strike claimed in claim 1, wherein the override mechanism blocks movement of the blocking element.

3. The electric strike claimed in claim 1, wherein the override mechanism moves the blocking element to the non-blocking position.

4. The electric strike claimed in claim 1, wherein the override mechanism is a mechanical override mechanism.

5. The electric strike claimed in claim 1, wherein the override mechanism comprises an override member that moves to reciprocates between a deadlocked position in which the override member prevents the blocking element from moving out of the blocking position, and an unlocked position in which the override member moves the blocking element into the unblocking position.

6. The electric strike claimed in claim 5, wherein the override member further moves to a neutral position between the deadlocked position and the unblocking position.

7. The electric strike claimed in claim 5, wherein the override mechanism comprises one or more mechanical actuators to actuate the override member into the deadlocked position or the unblocking position.

8. The electric strike claimed in claim 5, wherein the override member is a sliding bar having two contact surfaces joined by a bridge, wherein the blocking element is captured between the contact surfaces and slides along the bridge.

9. The electric strike claimed in claim 8, wherein a first surface of the two contact surfaces abuts the blocking element to prevent the blocking element from moving out of the blocking position.

10. The electric strike claimed in claim 8, wherein a second surface of the two contact surfaces pulls the blocking element out of the blocking position and into an unblocking position as the sliding bar moves to an unblocking position.

11. The electric strike claimed in claim 1, wherein a biasing member biases the override mechanism to a neutral position in which the override mechanism does not interfere with the electric actuator.

12. The electric strike claimed in claim 1, wherein the electric actuator is motor powered by a battery or the electric actuator is a solenoid hard wired into an electronic circuit.

13. The electric strike claimed in claim 1, further comprising a deadlock indicator on the body and visible from the exterior of the body.

14. The electric strike claimed in claim 1, wherein the electric actuator is actuated by a portable electronic device using a local wireless communication protocol.

15. The electronic strike claimed in claim 14, wherein the portable electronic device requires a Personal Identification Number (PIN) in order to actuate the electronic actuator.

16. The electric strike claimed in claim 5, wherein the override member further moves to a neutral position between the deadlocked position and the unlocked position.

17. The electric strike claimed in claim 5, wherein the override mechanism comprises one or more mechanical actuators to actuate the override member into the deadlocked position or the unlocked position.
