Electro-mechanical locks with bezel turning function

1. An electro-mechanical lock assembly comprising:

a housing configured to house the electro-mechanical lock assembly;

a keypad within the housing;

a motor operable upon a selective input from the keypad;

a gear driven by the motor;

a flower in selective engagement with the housing and gear such that when flower is engaged with the housing and gear all rotate in unison and when flower is not engaged with housing and gear all will not rotate in unison;

a torque member attached to the housing and selectively rotatable only when the flower is engaged with the gear;

a latch attached to the torque member thereby moving as the torque member is selectively rotated;

a bezel attached to the gear such that when the flower is engaged with both the gear and the housing, manual rotation of the bezel will rotate the housing; and

wherein the housing is selectively attached to the torque member which is configured to move the latch such that when the bezel rotates the latch is moved.

2. The electro-mechanical lock assembly of claim 1 , further comprising a base located adjacent the bezel and configured to fit against a door.

3. The electro-mechanical lock assembly of claim 1 , wherein the keypad is configured to receive a combination code as the selective input to operate the motor.

4. The electro-mechanical lock assembly of claim 1 , further comprising a cable ribbon in communication with a PCB board that determines if a proper combination code as the selective input is entered into the keypad to direct a signal to the motor to operate the motor.

5. The electro-mechanical lock assembly of claim 4 , wherein the cable ribbon is extendable from the electro-mechanical lock assembly and connectable to a battery case in a turnpiece assembly.

6. The electro-mechanical lock assembly of claim 5 , wherein the cable ribbon is supported by a support attached to the electro-mechanical lock assembly so the cable ribbon does not interfere with any backset assembly components that move a door latch or bolt.

7. The electro-mechanical lock assembly of claim 5 , wherein the turnpiece assembly includes a plate, a button, vibration dampening pads, a rose, and a knob.

8. The electro-mechanical lock assembly of claim 7 , wherein the button may engage a switch mechanism that is in communication with at least one battery in the battery case to send a signal through the ribbon cable to operate the motor.

9. The electro-mechanical lock assembly of claim 1 , further comprising a drive rod that is attached to the motor; wherein the drive rod rotates as the motor operates; a pin extends transversely through the drive rod and rotates with the drive rod; a spring is wound around the drive rod; a second spring extends from the flower to the housing; wherein the pin acts as a cam follower by engagement of the coil wire of the spring.

10. The electro-mechanical lock assembly of claim 9 , wherein engagement of the coil wire of the spring compresses or extends the spring along the longitudinal length of the drive rod; a carriage is movable back and forth along the drive rod such that as the spring expands or compresses the carriage is engagable with the flower such that as the pin extends or retracts the spring the flower is likewise pulled or pushed.

11. The electro-mechanical lock assembly of claim 10 , wherein the second spring is in compression so it biases the flower towards the pin.

12. The electro-mechanical lock assembly of claim 11 , wherein when the flower is moved to a location that is between both the housing and the gear, manually rotating the bezel which is attached to the gear, rotates the housing which is attached to and rotates the torque member.

13. The electro-mechanical lock assembly of claim 12 , wherein when the flower is not engaged to both the housing and the gear, the housing will not rotate the torque member.

14. The electro-mechanical lock assembly of claim 1 , wherein the torque member is attached to the housing by a second pin.

15. An electro-mechanical lock assembly comprising:

a housing configured to house the electro-mechanical lock assembly;

a motor operable upon a selective input;

a flower;

a driver;

a torque member;

a bezel;

wherein the motor is coupled to the driver to engage both the flower and the housing when the motor is in operation;

wherein the bezel is attached to the flower such that when the driver is engaged with both the flower and the housing, manual rotation of the bezel will rotate the housing; and

wherein the housing is attached to the torque member which is configured to move a latch such that when the bezel rotates the latch is moved.

16. The electro-mechanical lock assembly of claim 15 , further comprising a base located adjacent the bezel and configured to fit against a door.

17. The electro-mechanical lock assembly of claim 15 , further comprising a keypad that is configured to receive a combination code to operate the motor.

18. The electro-mechanical lock assembly of claim 15 , further comprising a cable ribbon in communication with a PCB board that determines if a proper combination code as the selective input is entered into the keypad to direct a signal to the motor to operate the motor.

19. The electro-mechanical lock assembly of claim 18 , wherein the cable ribbon is extendable from the electro-mechanical lock assembly and connectable to a battery case in a turnpiece assembly.

20. The electro-mechanical lock assembly of claim 19 , wherein the cable ribbon is supported by a support attached to the electro-mechanical lock assembly so the cable ribbon does not interfere with any backset assembly components that move a door latch or bolt.
