Abstract

An automatic door opening and closing device include a housing which may contain a control unit. A motor may be in electronic communication with the control unit, and a wheel may be coupled to the motor so that the motor may be operable to rotate the wheel in a clockwise direction and in a counter clockwise direction. A chassis may be configured to couple the motor to a door so that the wheel is in contact with a ground surface below the door. The motor may be operable to rotate the wheel clockwise across the ground surface to motivate the door in a first direction, and the motor may be operable to rotate the wheel counterclockwise across the ground surface to motivate the door in a second direction. By motivating the door in either the first direction or the second direction, the device may be configured to move the door into, out of, and between the open and closed positions.

Claims

1. An automatic door opening and closing device, the device comprising:

a. a control unit, the control unit having a radio module;

b. a motor in electronic communication with the control unit;

c. a wheel coupled to the motor;

d. a chassis for coupling the motor to a door so that the wheel is in contact with a ground surface, wherein the motor is operable to rotate the wheel; and

e. a translator in communication with the control unit, the translator comprising a processor, memory, and a power source, wherein the translator receives a first communication in a first protocol selected from one of;

a Wi-Fi protocol, a Bluetooth protocol, and a Zigbee protocol, and translates the first communication into a second communication in a second protocol, the second protocol an infrared protocol, the second communication receivable by the radio module of the control unit.

2. The device of claim 1, wherein the wheel is movably coupled to the chassis.

3. The device of claim 2, further comprising a tensioner configured to tension the wheel into contact with the floor surface.

4. The device of claim 3, wherein the chassis comprises a slide movably coupled within a channel and the tensioner is coupled to the slide and channel to tension the slide and channel away from each other.

5. The device of claim 1, further comprising a barrier sensor in communication with the control unit, wherein the control unit controls the motor to cease rotation of the wheel when the barrier sensor detects movement of the door is being blocked.

6. The device of claim 1, wherein the control unit controls the motor to cease rotation of the wheel when the radio module receives a wireless signal.

7. The device of claim 1, further comprising a remote control configured to generate a wireless signal, wherein the control unit controls the motor the rotate the wheel when the radio module receives the wireless signal.

8. The device of claim 1, wherein the control unit controls the motor the rotate the wheel when the radio module receives a wireless signal from a radio of a client device.

9. The device of claim 1, further comprising a transmission configured to resist rotation of the wheel not caused by the motor.

10. An automatic door opening and closing device, the device comprising:

a. a control unit, the control unit having a radio module;

b. a motor in electronic communication with the control unit;

c. a wheel coupled to the motor;

d. a chassis for movably coupling the wheel to a door so that the wheel is in contact with a ground surface, wherein the motor is operable to rotate the wheel;

e. a transmission comprising a single stage gear reducer configured to resist rotation of the wheel not caused by the motor;

the device further comprising a remote control configured to generate a wireless signal, wherein the control unit controls the motor to rotate the wheel when the radio module receives the wireless signal; and

wherein the control unit controls the motor to rotate the wheel when the radio module receives a wireless signal from a radio of a translator, the translator comprising a processor, memory, and a power source, wherein the translator receives a first communication in a first protocol from the remote control and translates the first communication into a second communication in a second protocol, the second communication receivable by the radio module of the control unit, the first protocol being different from the second protocol.

11. The device of claim 10, wherein the wheel comprises a flexible material.

12. The device of claim 10, wherein the device comprises a power source.

13. The device of claim 12, further comprising a tensioner configured to tension the wheel into contact with the floor surface.

14. The device of claim 10, wherein the chassis comprises a slide movably coupled within a channel and a tensioner coupled to the slide and channel to tension the slide and channel away from each other.

15. The device of claim 10, further comprising a barrier sensor in communication with the control unit, wherein the control unit controls the motor to cease rotation of the wheel when the barrier sensor detects movement of the door is being blocked.

16. The device of claim 10, wherein the control unit controls the motor to cease rotation of the wheel when the radio module receives a wireless signal.
