Abstract

A motorized air register, air diffuser or vent for HVAC systems in commercial and residential applications comprises a supporting frame abutting a floor, wall or ceiling and a second depending frame for enclosing a damper. The damper is motor driven from a first fully open position to a second fully closed position. The damper can be controlled remotely from a wall consol or in accordance with thermostat logic.

Claims

1. A motorized air vent for controlling an air flow, said motorized air vent comprising:

a. A first rectangular frame adapted for supported placement abutting a planar surface;

b. Air diffusion means mounted within said first rectangular frame;

c. A second rectangular frame depending from the first rectangular frame;

d. Vent closure means mounted operatively within said second rectangular frame and positioned adjacent to said air diffusion means; and

,

e. Means for sliding said vent closure means open and closed wherein said means for sliding is in an operative relationship with the air diffusion means permitting said air flow control.

2. The motorized air vent of claim 1 wherein the first rectangular frame is sized for placement around a rectangular hole in said planar surface, wherein said rectangular hole terminates an air duct and wherein the rectangular hole is sized to receive said second rectangular frame in an air tight and positional agreement so that the air flow is directed to the air diffusion means.

3. The motorized air vent of claim 2 wherein the first rectangular frame supports the motorized air vent within the rectangular hole.

4. The motorized air vent of claim 3 wherein said planar surface is one of a floor surface, a wall surface and a ceiling surface.

5. The motorized air vent of claim 4 wherein said air diffusion means comprises a first mesh pattern adapted for omni-directional air diffusion.

6. The motorized air vent of claim 5 wherein said first mesh pattern comprises a plurality of equally spaced and parallel horizontal and vertical members forming a matrix of equally sized rectangular apertures.

7. The motorized air vent of claim 6 wherein said vent closure means comprises a thin rectangular damper comprising a second matrix matching said first matrix so that when said second matrix and the first matrix coincide the motorized air vent is full open and when the second matrix and the first matrix are fully offset, the motorized air vent is fully closed.

8. The motorized air vent of claim 7 wherein the motorized air vent is partially open when the first and second matrices are partially offset.

9. The motorized air vent of claim 2 wherein the second rectangular frame comprises a first and a second parallel long side rectangular members and a first and a second parallel short side rectangular members joined together and defining a rectangular bulkhead dimensioned to fit snuggly within the rectangular hole while allowing easy removal of the motorized air vent from the rectangular hole.

10. The motorized air vent of claim 9 wherein said rectangular damper is permitted a sliding action within said rectangular bulkhead between a fully open position and a fully closed position.

11. The motorized air vent of claim 10 wherein the rectangular damper is permitted said sliding action by said means for sliding.

12. The motorized air vent of claim 11 wherein the means for sliding comprises a mounting plate disposed beneath the rectangular damper and supportively attached width-wise to the second rectangular frame, an electric motor, a battery in communication with said electric motor and actuation means in mechanical communication between the rectangular damper and the electric motor so as to provide a sliding motion to the rectangular damper.

13. The motorized air vent of claim 12 wherein said mounting plate comprises a top surface, a bottom surface and a central aperture, and further wherein the mounting plate is mounted width-wise across the second rectangular frame by mounting means.

14. The motorized air vent of claim 13 wherein said battery is mounted to said bottom surface by battery mounting means, and wherein said battery mounting means includes electrical contact means mounted to said top surface and in communication with the electric motor.

15. The motorized air vent of claim 14 wherein said top surface mounts electric motor control means.

16. The motorized air vent of claim 15 wherein the electric motor includes a drive shaft and is disposed below the mounting plate and mounted thereto by second mounting means so that said drive shaft protrudes through said central aperture.

17. The motorized air vent of claim 16 wherein said actuation means is mounted to the drive shaft and disposed above the mounting plate and comprises a rotatable cam body.

18. The motorized air vent of claim 17 wherein said cam rotatable body has a cylindrical bottom portion axially attached to the drive shaft and a cam head top portion adapted for engagement with a complementary aperture centrally disposed in the rectangular damper.

19. The motorized air vent of claim 18 wherein the rotation of said cam head within said complementary aperture moves the rectangular damper between fully open and fully closed.

20. The motorized air vent of claim 19 wherein said motor control means restricts the rotation of the drive shaft to about 180 degrees.
