Abstract

In a window covering system with a shade roll, a counterbalanced motorized shade roll system includes a shade roll with a hollow interior connected with a window covering system. A motor is located within the hollow interior. A torsion spring is also located within the hollow interior of the shade roll and the torsion spring is connected with the motor on one end and with the hollow interior on another end. Batteries are also located within the hollow interior of the shade roll opposite from the motor and after the connection of the torsion spring with the hollow interior of the shade roll such that the torsion spring does not surround the batteries.

Claims

1. In a window covering system with a shade roll, a counterbalanced motorized shade roll system comprising:

a. a shade roll with a hollow interior connected with a window covering system;

b. a motor located within said hollow interior;

c. a torsion spring within said shade roll wherein said torsion spring is connected with said motor on one end and with said hollow interior on another end; and

d. batteries located within said hollow interior of said shade roll opposite from said motor and after said connection of said torsion spring with said hollow interior of said shade roll such that said torsion spring does not surround said batteries.

2. The apparatus of claim 1 further including a reduction gear connected with said motor.

3. The apparatus of claim 1 further including a liner in said hollow interior of said shade roll.

4. The apparatus of claim 3 wherein said liner surrounds said torsion spring.

5. The apparatus of claim 3 wherein said torsion spring surrounds said liner.

6. The apparatus of claim 1 wherein said torsion spring at least partially surrounds said motor.

7. The apparatus of claim 1 wherein said motor is connected with a drive shaft and said drive shaft is connected with a drive cone connected within said hollow interior.

8. The apparatus of claim 7 wherein said torsion spring is connected on one end with said drive cone.

9. The apparatus of claim 7 wherein said drive cone is conformed to surround a length of said drive shaft and said drive cone is moveable along said length of said drive shaft.

10. In a window covering system with a shade roll, a counterbalanced motorized shade roll system comprising:

a. a shade roll with a hollow interior connected with a window covering system;

b. a motor located within said hollow interior and connected with said window covering system;

c. a reduction gear connected with said motor;

d. a drive shaft connected with said motor wherein said drive shaft is connected with a drive cone connected within said hollow interior

e. a torsion spring within said shade roll wherein said torsion spring is connected with said motor on one end and with said hollow interior on another end; and

f. batteries located within said hollow interior of said shade roll opposite from said motor and after said connection of said torsion spring with said hollow interior of said shade roll such that said torsion spring does not surround said batteries.

11. The apparatus of claim 10 wherein said reduction gear is a two stage planetary reduction gear.

12. The apparatus of claim 10 further including a liner in said hollow interior of said shade roll.

13. The apparatus of claim 12 wherein said liner surrounds said torsion spring.

14. The apparatus of claim 12 wherein said liner includes a first liner that surrounds said torsion spring and a second liner which said torsion spring surrounds such that said torsion spring is located between said first liner and said second liner.

15. The apparatus of claim 10 wherein said torsion spring at least partially surrounds said motor.

16. The apparatus of claim 10 wherein said torsion spring is connected on one end with said drive cone.

17. In a window covering system with a shade roll, a counterbalanced motorized shade roll method comprising:

a. providing a shade roll with a hollow interior connected with a window covering system;

a motor located within said hollow interior and connected with said window covering system;

a torsion spring within said shade roll wherein said torsion spring is connected with said motor on one end and with said hollow interior on another end; and

batteries located within said hollow interior of said shade roll opposite from said motor and after said connection of said torsion spring with said hollow interior of said shade roll such that said torsion spring does not surround said batteries; and

b. activating said batteries to move said shade roll.

18. The method of claim 17 further including a reduction gear connected with said motor.

19. The method of claim 17 further including a liner in said hollow interior of said shade roll.

20. The method of claim 17 wherein said motor is connected with a drive shaft and said drive shaft is connected with a drive cone connected within said hollow interior.
