Abstract

An electronic and manual lock assembly having a lock housing, a mechanical lock, an electric motor, and a shackle having a pair of legs. The shackle can be unlocked relative to the housing by having one leg pivotally connected with the housing and the other leg rotated out of the housing. The lock includes a first stop member that prevents one leg from being rotated out of the housing. The first stop member is moveable as a result of unlocking the mechanical lock. The lock includes a second stop member that prevents one of the legs from being rotated out of the lock housing and is moveable as a result of operating the electric motor. The first stop member and the second stop member are independently moveable by the mechanical lock and the electric motor.

Claims

1. An electronic and manual lock assembly comprising:

a lock housing;

a mechanical lock carried by the lock housing;

an electric motor carried by the lock housing;

a shackle having a pair of legs, the shackle configured to be unlocked relative to the lock housing by having one of the legs pivotally connected with the lock housing and the other of the legs rotated out of the lock housing;

a first stop member operable to prevent one of the legs from being rotated out of the lock housing through a first side opening in the lock housing, the first stop member being moveable as a result of unlocking the mechanical lock to enable one of the legs to be rotated out of the lock housing; and

a second stop member operable to prevent one of the legs from being rotated out of the lock housing through a second side opening in the lock housing, the second stop member being moveable as a result of operating the electric motor to enable one of the legs to be rotated out of the lock housing;

wherein the first stop member and the second stop member being independently moveable by the mechanical lock and the electric motor respectively.

2. The lock of claim 1, wherein the first stop member is a slideable panel located on one side of the lock housing such that in the unlocked position, a second leg of the pair of the legs is rotatable out of the lock housing in a first direction.

3. The lock of claim 2, wherein the second stop member is a slideable panel located on another side of the lock housing such that in the unlocked position, the second leg of the pair of the legs is rotatable out of the lock housing in a second direction.

4. The lock of claim 1, wherein the mechanical lock comprises a key cylinder.

5. The lock of claim 1, wherein the mechanical lock comprises a combination lock.

6. The lock of claim 1, further comprising a controller constructed and arranged to be in communication with the motor.

7. The lock of claim 6, wherein the controller comprises a radio frequency receiver configured to receive signals comprising an unlock code from an electronic key.

8. The lock of claim 7, wherein the electronic key comprises a radio frequency transmitter configured to transmit signals comprising an unlock code.

9. The lock of claim 7, wherein the lock comprises a slot constructed and arranged to receive the electronic key.

10. The lock of claim 7, wherein the controller comprises memory configured to store unlock codes, and wherein the controller is configured to compare the unlock code received from the electronic key to the unlock codes stored in memory to determine if the unlock code received from the electronic key is an authorized unlock code.

11. The lock of claim 10, wherein the controller is constructed and arranged to enable the motor to move the second stop member to the unlocked position in response to an authorized unlock code transmitted from the electronic key.

12. The lock of claim 6, further comprising an encoder constructed and arranged to be operatively connected to a rotatable component of the mechanical lock and in communication with the controller.

13. The lock of claim 12, wherein electric signals sent by the encoder to the controller enable the controller to determine an angular position of the rotatable component of the mechanical lock.

14. The lock of claim 13, wherein the electric signals sent by the encoder to the controller in response to the angular position of the rotatable component of the mechanical lock are associated with operations that the controller is configured to perform.

15. The lock of claim 14, wherein the operations comprise adding or deleting unlock codes from memory.

16. The lock of claim 12, further comprising a guide structure constructed and arranged to connect the encoder to the rotatable component, wherein rotation of the rotatable component rotates the guide structure and the encoder.

17. The lock of claim 16, further comprising an indicator constructed and arranged to operate with the rotatable component to indicate that a selected position of the rotatable component has been reached during rotation of the mechanical lock.

18. The lock of claim 17, wherein the indicator comprises a spring loaded ball constructed and arranged to be received in a detent formed in the guide structure during rotation of the rotatable component.

19. The lock of claim 12, wherein the rotatable component comprises a key cylinder.

20. An electronic and manual lock assembly comprising:

a lock housing;

a shackle having a pair of legs, the shackle being unlockable relative to the lock housing by having at least one of the legs being moved out of the lock housing through a side opening in the lock housing;

a controller having a memory configured to store unlock codes transmitted from at least one electronic key;

an electric motor carried by the lock housing and configured to be moveable by the controller to unlock the shackle relative to the lock housing based on the unlock codes received by the controller from the at least one electronic key; and

a mechanical lock carried by the lock housing and moveable by a mechanical key between a plurality of positions;

wherein movement of the mechanical lock by the mechanical key to a first position of the plurality of positions enables the controller to add unlock codes to the memory and movement of the mechanical lock by the mechanical key to a second position of the plurality of positions unlocks the shackle relative to the lock housing.

21. The lock of claim 20, wherein movement of the mechanical lock by the mechanical key to a third position of the plurality of positions enables the controller to delete unlock codes from the memory.

22. The lock of claim 21, wherein the first and third positions are different positions.

23. The lock of claim 21, wherein the first and third positions are the same positions.

24. The lock of claim 21, further comprising an encoder operatively connected to the mechanical lock such that movement of the mechanical lock by the mechanical key effects the encoder to send signals associated with the position of the mechanical lock to the controller.

25. The lock of claim 24, wherein the encoder is an incremental encoder.

26. The lock of claim 24, further comprising a guide structure that connects the mechanical lock to the encoder such that movement of the mechanical lock effects movement of the encoder.

27. The lock of claim 20, further comprising an electric motor carried by the lock housing and moveable by an electronic key configured to transmit radio frequency signals comprising unlock codes.

28. The lock of claim 27, wherein movement of the electric motor by the electronic key unlocks the shackle relative to the lock housing.

29. The lock of claim 20, wherein the mechanical lock comprises a lock cylinder.
