Abstract

A door lock system includes a knob and an apparatus that controls transmission of displacement or rotational mechanical energy. A bolt is coupled to a door, an input rod and an output rod. At least one of an interior or exterior knob is coupled to the bolt and the apparatus that controls transmission of displacement or rotational mechanical energy. An energy source is coupled to the apparatus that controls transmission of displacement or rotational mechanical energy. The mobile device provides authorization to engage the apparatus that controls transmission of displacement or rotational mechanical energy and allows a door user to manually open the door.

Claims

1. A door lock system with a knob comprising:

a position sensing device to sense position of a drive shaft of the door lock system to assists in locking and unlocking the bolt in response to communication with an user'"'"'s mobile device;

an engine with a memory coupled to the position sensing device and a wireless communication device, the engine executing instructions received from the user'"'"'s mobile device to execute operation of the door lock system;

an energy source coupled to position sensing device and the engine to supply energy therein;

the door lock system with a proximity sensor configured to provide that when the user'"'"'s mobile device is at an exterior of a dwelling and in a close proximity to the dwelling, the user'"'"'s mobile device is utilized to unlock the door;

an apparatus that controls transmission of displacement or rotational mechanical energy coupled to the position sensing device and the engine;

a bolt coupled to a door, the bolt coupled to an input rod and an output rod, the bolt locking and unlocking a door in response transmission of displacement or delivery of rotational mechanical energy when the actuation device is actuated by the user'"'"'s mobile device;

the wireless communication device coupled to the apparatus and in communication with a mobile device, with the mobile device providing authorization to engage the apparatus to controls transmission of displacement or rotational mechanical energy and allows a user to manually open the door; and

a haptic device provides a visual indication that the bolt of lock device has reached a home open position verses a final position so user does not over-torque when turn the knob to open the door after the door lock system received authorized from the mobile device.

2. The system of claim 1, further comprising:

an actuator coupled to the apparatus that controls transmission of displacement or rotational mechanical energy, the actuator enabling enable the apparatus to provide its operation of transmission of displacement or rotational mechanical energy to the bolt.

3. The system of claim 1, further comprising:

an audio or visual indicator that provides a confirmation of a door locking.

4. The system of claim 1, wherein the system is configured to identify the door user based on a door user'"'"'s habits.

5. The system of claim 1, wherein the door is unlocked by movement of the input rod, output rod and the bolt.

6. The system of claim 1, wherein the energy source is one or more batteries.

7. The system of claim 6, wherein the batteries are positioned in an interior of the knob.

8. The system of claim 1, wherein the knob has a first end section and a section end section.

9. The system of claim 8, wherein the first end section is closer to the to the door bolt than the second end section.

10. The system of claim 8, wherein the apparatus that controls transmission of displacement or rotational mechanical energy is at the first end section of the knob.

11. The system of claim 8, wherein the apparatus that controls transmission of displacement or rotational mechanical energy is in an interior of the first end section.

12. The system of claim 1, wherein the energy source and the wireless communication device are positioned in an interior of the knob.

13. The system of claim 1, wherein following authorization the apparatus that controls transmission of displacement or rotational mechanical is operated and engaged.

14. The system of claim 1, wherein following authorization, the knob is moved which causes the output rod to move.

15. The system of claim 1, further comprising:

a device that converts energy into mechanical energy coupled to a circuit, the input rod and the device that converts energy being coupled to the energy source to receive energy from the energy source.

16. The system of claim 1, wherein the input rod and the output rod are inter-changeable relative to door opening and access.

17. The system of claim 1, wherein the device that converts energy into mechanical energy imparts movement to the input rod.

18. The system of claim 1, further comprising:

an RF transmitter or receiver.

19. The system of claim 1, further comprising:

a knock sensor.

20. The system of claim 1, further comprising:

an audio speaker or audio microphone coupled to the circuit.

21. The system of claim 1, further comprising:

one or more LED'"'"'s coupled to the circuit.

22. The system of claim 1, further comprising:

one or more buttons for locking.

23. The system of claim 1, wherein the knob is a door handle.

24. The system of claim 1, further comprising:

a circuit; and

an engine with a memory coupled to the circuit and the wireless communication device.

25. The system of claim 1, wherein the apparatus that controls transmission of displacement or rotational mechanical energy is a clutch with first and second elements configured to be engaged and disengaged.
