Abstract

An air register can control airflow direction and intensity. The air register includes an attachment mechanism that is configured to attach to a surface. The air register further includes a plurality of diffuser discs attached to the attachment mechanism and configured so that they may be manually moved from a closed configuration to an open configuration. The diffuser discs include a plurality of apertures that allow air to flow therethrough. In the closed configuration, the diffuser discs are arranged to cover the apertures so that air cannot flow therethrough. In the open configuration, the plurality of diffuser discs are spaced apart to allow air to flow through the apertures. Further, the diffuser discs can be tilted to control airflow direction.

First claim

The invention claimed is:

1. An air register, comprising:
an attachment member configured to be attached to a surface;
a first diffuser disc coupled to the attachment member, the first diffuser disc including at least one first diffuser disc aperture extending therethrough;
a tilt member coupled to the first diffuser disc within a central aperture thereof, wherein the tilt member is a tilt ring that includes tilt ring semi-circular apertures; and
a second diffuser disc coupled to the tilt member and configured to cover the at least one first diffuser disc aperture when in a closed position and be spaced from the first diffuser disc when in an open position,
wherein the tilt member allows for rotation and tilting of the second diffuser disc.

2. The air register of claim 1 , wherein the at least one first diffuser disc aperture is formed by a cylindrical flange that extends inwardly from the first diffuser disc.

3. The air register of claim 1 , wherein the first diffuser disc further includes a plurality of apertures extending therethrough, wherein the second diffuser disc is configured to cover the plurality of apertures when in the closed position.

4. The air register of claim 1 , wherein the attachment member is an attachment ring that includes a cylindrical wall with a lip extending outwardly from a first end thereof, and wherein the cylindrical wall is configured to be inserted into and retained within a cavity in the surface, and the lip is configured to abut the surface.

5. The air register of claim 4 , wherein the first diffuser disc is retained on an outer side thereof by a portion of the lip that extends inwardly of the cylindrical wall of the attachment ring.

6. The air register of claim 4 , wherein the first diffuser disc is retained on an inner side thereof by a plurality of ridges extending inwardly from and spaced around the cylindrical wall.

7. The air register of claim 6 , wherein the plurality of ridges comprises four equally-spaced ridges.

8. The air register of claim 1 , wherein the second diffuser disc includes at least one second diffuser disc aperture and two semi-circular apertures extending therethrough, wherein the two semi-circular apertures are positioned on opposing sides of the second diffuser disc aperture, and the air register further includes:
a third diffuser disc member coupled to the second diffuser disc and configured to cover the at least one second diffuser disc aperture when in the closed position and be spaced from the second diffuser disc when in the open position,
wherein the tilt member allows for rotation and tilting of the third diffuser disc.

9. The air register of claim 8 , wherein the first, second, and third diffuser discs are circular in shape.

10. The air register of claim 8 , wherein the third diffuser disc includes an inner surface, an outer surface, and a third diffuser disc latch that extends from the inner surface and through the second diffuser disc aperture.

11. The air register of claim 8 , wherein the third diffuser disc includes a knob, wherein the knob is configured to allow a user to pull the third diffuser disc outwardly from the second diffuser disc and the second diffuser disc outwardly from the first diffuser disc, which arranges the air register in the open position.

12. The air register of claim 8 , wherein the tilt ring includes a central circular aperture, the two tilt ring semi-circular apertures, and at least one slot positioned between the two tilt ring semi-circular apertures.

13. The air register of claim 12 , wherein when in the open position, airflow moves through the tilt ring semi-circular apertures, through the semi-circular apertures in the second diffuser disc, and around the third diffuser disc.

14. An air register, comprising:
an attachment member configured to be attached to a surface;
a first diffuser disc coupled to the attachment member, the first diffuser disc including at least one first diffuser disc aperture extending therethrough;
a tilt member coupled to the first diffuser disc, wherein the tilt member is a tilt ring that includes a central circular aperture, two semi-circular apertures, and at least one slot positioned between the tilt ring semi-circular apertures;
a second diffuser disc including at least one second diffuser disc aperture extending therethrough, wherein the second diffuser disc is coupled to the tilt member and configured to cover the at least one first diffuser disc aperture when in a closed position and be spaced from the first diffuser disc when in an open position; and
a third diffuser disc member coupled to the second diffuser disc and configured to cover the at least one second diffuser disc aperture when in the closed position and be spaced from the second diffuser disc when in the open position,
wherein the tilt member allows for rotation and tilting of the second diffuser disc and the third diffuser disc.

15. The air register of claim 14 , wherein the second diffuser disc includes two semi-circular apertures extending therethrough and are positioned on opposing sides of the second diffuser disc aperture.

16. The air register of claim 15 , wherein the second diffuser disc further includes an inner wall and at least one leg extending therefrom, wherein a latch is positioned at an inner end of the at least one leg.

17. The air register of claim 16 , wherein the second diffuser disc further includes a detent positioned between the inner end and an outer end of the at least one leg.

18. The air register of claim 17 , wherein the at least one leg is configured to extend through the at least one slot of the tilt ring.

19. The air register of claim 18 , wherein the third diffuser disc includes an inner surface, an outer surface, a third diffuser disc latch that extends from the inner surface and through the second diffuser disc aperture, and a knob that is configured to allow a user to pull the third diffuser disc outwardly from the second diffuser disc and the second diffuser disc outwardly from the first diffuser disc, which arranges the air register in the open position.

20. An air register, comprising:
an attachment member configured to be attached to a surface, wherein the attachment member is an attachment ring that includes a cylindrical wall with a lip extending outwardly from a first end thereof, and wherein the cylindrical wall is configured to be inserted into and retained within a cavity, and the lip is configured to abut the surface;
a first diffuser disc coupled to the attachment member, the first diffuser disc including at least one first diffuser disc aperture that is formed by a cylindrical flange that extends inwardly from the first diffuser disc;
a tilt member coupled to the first diffuser disc, wherein the tilt member is a tilt ring that includes a central circular aperture, two semi-circular apertures, and at least one slot positioned between the tilt ring semi-circular apertures;
a second diffuser disc that includes at least one second diffuser disc aperture and two semi-circular apertures extending therethrough, the two semi-circular apertures positioned on opposing sides of the second diffuser disc aperture, wherein the second diffuser disc is coupled to the tilt member and configured to cover the at least one first diffuser disc aperture when in a closed position and be spaced from the first diffuser disc when in an open position; and
a third diffuser disc member coupled to the second diffuser disc and configured to cover the at least one second diffuser disc aperture whe
