Abstract

An enhanced bolt control system for safes and the like utilizes a reversible motor and worm gear drive that operates the deadbolt linkage. An electronic control with a microcomputer interface drives the motor control and the system may be operated by a keypad or a remote wireless control device.

Claims

1. A locking system for safes and the like wherein a door is locked and unlocked to a cabinet, comprising in combination, a motor means carried either by the door or cabinet, said motor means rotatably connected to a mechanical linkage having locked and unlocked positions, and control means for driving said motor to move said linkage from the locked to the unlocked position.

2. A locking system as claimed in claim 1, wherein said motor means is driven to move said linkage from the unlocked to the locked position.

3. A locking system as claimed in claim 1, wherein said motor is a two-direction reversible motor.

4. A locking system as claimed in claim 1, wherein said locked position of said linkage is force resisting.

5. A locking system as claimed in claim 1, wherein said motor means drives said mechanical linkage means through gear reduction means.

6. A locking system as claimed in claim 5, wherein said gear reduction means includes first reduction gears, and a second gear reduction means.

7. A locking system as claimed in claim 6, wherein said second gear reduction means includes a worm gear and a helical gear.

8. A locking system as claimed in claim 7, wherein said helical gear is interfaced to at least 2 teeth of the worm gear.

9. A locking system as claimed in claim 4, wherein said motor means includes an access control means.

10. A locking system as claimed in claim 9, wherein said access control means is remotely operable.

11. A locking system as claimed in claim 9, including an override means for energizing said motor independent of said motor control means and access control means.

12. A locking system as claimed in claim 9, wherein the control means and motor are powered by a battery source.

13. A locking system as claimed in claim 9, wherein position switch means provides a lock trigger signal for energizing said motor to lock the deadbolt means.

14. A locking system as claimed in claim 9, wherein said access control means is operated by an access input means carried by the door or cabinet.

15. A locking system as claimed in claim 4, wherein sensing means is included for said motor to detect motor current and either reverse the motor direction or deenergize the motor upon reaching predetermined current levels.

16. A locking system as claimed in claim 9, wherein said access control means is operable only by input of a unique preset access code signal.

17. A locking system as claimed in claim 9, wherein said control includes a battery saver sleep mode and an operational mode upon input of an access signal.

18. A method of unlocking a door to a cabinet wherein deadbolt means is carried by either the door or cabinet and mechanical linkage means moves the deadbolt means for unlocking the door with the cabinet comprising providing motor means with an electronic motor control to drive the mechanical linkage means between a force resisting locked position and an open position and powering said motor to drive the linkage thereby unlocking the deadbolt means.

19. A method as claimed in claim 18, including providing microcomputer means for directing operation of said electronic motor control and motor.

20. A method as claimed in claim 19, wherein access control means is provided including provision for operating said locking system external to the door and cabinet.

21. A locking system for safes and the like wherein a door is locked and unlocked to a cabinet on which the door is pivotally mounted, comprising in combination, a deadbolt means carried either by the door or cabinet, mechanical linkage means for moving the deadbolt means for unlocking the door from the cabinet, a motor means connected for driving the mechanical linkage means from force resisting locked position to open position, and a motor control for operating the motor to drive the mechanical linkage means to unlock the deadbolt means between the door and cabinet.

22. A locking system as claim in claim 21, wherein said motor is rotatably connected for driving the mechanical linkage.

23. A locking system as claim in claim 22, wherein said motor is further rotatably connected for driving the mechanical linkage from open position to force resisting locked position and said motor control operates the motor to drive the mechanical linkage means to lock the deadbolt means between the door and cabinet.

24. A locking system as claimed in claim 21, wherein said motor means includes an access control means.

25. A locking system as claimed in claim 24, wherein said control includes a battery saver sleep mode and an operational mode upon input of an access signal.

26. A locking system as claimed in claim 21, wherein said motor is reversible and operable in two directions to move the deadbolt means.

27. A locking system as claimed in claim 21, wherein said motor is reversible and operable in one direction to move the deadbolt means.
