Abstract

Provided is an electronic curtain moving device. Thus device can comprise: a pulley operably connected to a motor, the pulley having a groove through which a cord of a curtain travels, wherein the pulley can move in clockwise and counter-clockwise directions; a head capable of movement from a first and a second position; Wherein movement of the pulley in the clockwise direction makes the head move to the first position and make contact with the cord, and movement of the pulley in the counter-clockwise direction makes the head move to the second position and make contact with the cord at a different location than contact at the first position.

Claims

1. An electronic device for movement of a curtain comprising:

a. a pulley operably connected to a motor, the pulley having a groove through which a cord of a curtain travels, wherein the pulley can move in clockwise and counter-clockwise directions;

b. a head capable of movement from a first and a second position;

Wherein movement of the pulley in the clockwise direction makes the head move to the first position and make contact with the cord, and movement of the pulley in the counter-clockwise direction makes the head move to the second position and make contact with the cord at a different location than contact at the first position.

2. The device of claim 1, wherein the head is operably connected to a motor separate from the motor of the pulley.

3. The device of claim 1, wherein the pulley has a V shaped groove for placement of the cord and the groove of the pulley has a textured plastic coating that creates a non-uniform surface.

4. The device of claim 1, wherein weight of the device is supported by the cord, allowing the device to move downward in the event that the cord stretches overtime, providing a tight connection between the pulley and the cord all the time.

5. The device of claim 4, wherein device is placed in a rail system attached to the wall that limits the movement of the device in lateral and upward direction.

6. The device of claim 1, wherein device comprises a first and second section pivotally attached to each other, wherein the first section pivots clockwise and counterclockwise in direction of movement of the pulley to allow for contact between the head and the cord.

7. The device of claim 1, wherein the device determines the position of beginning and ending of the curtain rod based on amperage that the pulley motor uses.

8. The device of claim 7, wherein the device terminates operation of pulling the cord when the motor amperage exceeds a predetermined level.

9. The device of claim 8, wherein the device upon termination of the operation allows free movement of the pulley, the free movement resulting in release of tension existing in the cord.

10. The device of claim 8, wherein the predetermined level indicates a full open or full closed position.

11. The device of claim 8, wherein the predetermined level indicates an obstacle.

12. The device of claim 1, wherein the device measures amperage of the motor a plurality of times every second.

13. The device of claim 1, wherein the device self-programs its action based on prior use.

14. The device of claim 1, wherein the device can open and close the curtain randomly to provide an impression that a person is opening and closing the curtain.

15. The device of claim 1, wherein the device can close the curtain in direct sun light.

16. The device of claim 1, wherein the device can be remotely controlled.

17. The device of claim 1, wherein the device automatically pulls the cord to fully open or fully close the curtain based on pre-set time of day.

18. A method for operating a curtain comprising using the device of claim 1.

19. An electronic device for movement of a curtain comprising a pulley operably connected to a motor, the pulley having a groove through which a cord of a curtain travels, wherein the pulley can move in clockwise and counter-clockwise directions;

wherein weight of the device rests on the cord.

20. An electronic device for movement of a curtain comprising:

a) An operation compartment comprising

i) A pulley operably connected to a first motor, the pulley having a groove through which a cord of a curtain travels, wherein the pulley can move in clockwise and counter-clockwise directions;

ii) A head operably connected to a second motor capable of movement from a first and a second position;

wherein movement of the pulley in the clockwise direction makes the head move to the first position and make contact with the cord, and movement of the pulley in the counter-clockwise direction makes the head move to the second position and make contact with the cord at a different location than contact at the first position;

b) A control compartment comprising mechanical and electronic hardware for making the head and the pulley work;

wherein the operation compartment is placed in a rail system that limits lateral or upward movement of the operation compartment;

wherein the weight of the device rests on the cord;

wherein the first motor has a shaft that creates a pivot point, allowing the control compartment to pivot in relation to the operation compartment, direction of the pivot determined by direction of rotation of the pulley.
