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 control compartment;

b. an operation compartment;

c. an automatic rail system;

d. a head system;

e. a main motor; and

f. a head motor;

wherein said head system has two main functions;

i. said head system travels from a first position to a second position or vice versa, wherein rotation of a main motor drive shaft in the clockwise direction pulls a control cord of said curtain in the clockwise direction and makes said head system travel to the first position and make contact with said control cord at the first position, and the rotation of said main motor drive shaft in the counter-clockwise direction pulls said control cord of said curtain in the counter-clockwise direction and makes said head system travel to the second position and make contact with said control cord in said second position;

ii. said head system is rotated using a head motor drive shaft which rotates in clockwise and counter-clockwise directions, after contact between said head system and said control cord occurs in said first position the head system is rotated in a clockwise direction to pull the control cord that is in an extended position out of the operation compartment, and after contact between said head system and control cord occurs in said second position the head system is rotated in a counter-clockwise direction which pulls the control cord that is in an extended position out of said operation compartment;

wherein when said main motor drive shaft rotates clockwise said head motor drive shaft rotates clockwise too, and when said main motor drive shaft rotates counter-clockwise, said head motor drive shaft rotates counter-clockwise too.

2. The device of claim 1, wherein said head system is operably connected to said head motor separate from said main motor.

3. The device of claim 1, wherein said operation compartment is placed in said automatic rail system attached to a wall proximate a window therein at an approximate mid-vertical height of said window, which automatically allows movement of said operation compartment downward when said control cord stretches over time providing a tight connection between a pulley and said control cord, and automatically locks said operation compartment which limits said operation compartment from upward movement and lateral movement.

4. The device of claim 1, wherein said control compartment and said operation compartment are pivotally attached to each other, wherein the said control compartment pivots clockwise and counter-clockwise in a direction of a movement of said main motor to facilitate contact between said head system and said control cord.

5. The device of claim 1, wherein when the device reaches a full opened or closed position of the curtain, said main motor, which is connected to said pulley, moves in an opposite direction for 0.5 seconds, the opposite direction movement results in a release of tension existing in said control cord.

6. 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 a weight of greater than 1 pound, associated with a total 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.

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

a. an operation compartment comprising;

i. a main motor with a main motor drive shaft connected to a pulley through which a control cord of a curtain travels wherein said main motor drive shaft rotates in clockwise and counter-clockwise directions;

ii. a head motor is connected to a head system through a head motor drive shaft, wherein said head system has two primary functions;

1. said head system moves from a first position and a second position wherein the rotation of said main motor drive shaft in the clockwise direction makes said head system move to a first position and make contact with said control cord at said first position, and rotation of said main motor drive shaft in the counter-clockwise direction makes said head system move to said second position and make contact with said control cord at said second position; and

2. the said head system is connected to said head motor drive shaft of said head motor which rotates in clockwise and counter-clockwise directions, wherein after said head system and said control cord make contact with one another at either the first position or second position the rotation of said head motor drive shaft pulls the control cord that is in an extended position out of said operation compartment, wherein when said main motor drive shaft rotates clockwise, said head motor drive shaft rotates clockwise too, and when said main motor drive shaft rotates counter-clockwise said head motor drive shaft rotates counter-clockwise too;

b. a control compartment comprising;

i. mechanical hardware; and

ii. electronic hardware;

wherein said mechanical hardware and said electronic hardware make said head system and said main motor work,

c. an automatic rail system wherein the said operation compartment is placed in said automatic rail system attached to a wall proximate a window therein at an approximate mid-vertical height of said window, which automatically allows the movement of said operation compartment downward when said control cord stretches over time providing a tight connection between said pulley and said control cord and wherein said rail system automatically limits from upward or lateral movement of the operation compartment;

wherein the weight of the device which is 1.65 pounds rests on said control cord;

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