Abstract

A ventilation grille having a trim ring and a plate releasably connected to the trim ring. The trim ring defines an aperture allowing connection of the trim ring to a main housing of a ventilation system defining an internal region in which a blower is located. The plate is releasably connected to the trim ring to allow access to the trim ring aperture for connection of the trim ring to the main housing or blower and disconnection of the trim ring from the main housing or blower.

First claim

We claim:

1. A ventilation system comprising
a main housing defining an internal region and the main housing configured to be positioned adjacent to a room of a building structure,
a blower in the internal region and configured to draw air out of the room of the building structure, and
a grille configured to at least partially block view of the main housing and the blower, the grille comprising:
a trim ring releasably connectable to the main housing or the blower by a grille spring, the trim ring defining an aperture through which the air is configured to flow and providing access to the main housing or blower when the trim ring is connected to the main housing or blower; and
a plate configured to releasably connect to the trim ring to cover the aperture.

2. The system of claim 1 , wherein the trim ring aperture provides access to the grille spring when the trim ring is connected to the main housing or blower.

3. The system of claim 1 , wherein the plate is releasably connected to the trim ring by an attachment mechanism.

4. The system of claim 1 , wherein the plate is releasably connected to the trim ring by an attachment mechanism and the attachment mechanism comprises a magnet.

5. The system of claim 1 , wherein the plate defines apertures to allow movement of air through the plate.

6. A grille configured to be connected to a ventilation system comprising a main housing defining an internal region and a blower in the internal region and configured to move air, the grille comprising:
a trim ring releasably connectable to the main housing or the blower by a grille spring, the trim ring defining an aperture through which the air is configured to flow and providing access to the main housing or blower when the trim ring is connected to the main housing or blower; and
a plate configured to releasably connect to the trim ring to cover the aperture.

7. The grille of claim 6 , wherein the trim ring aperture provides access to the grille spring when the trim ring is connected to the main housing or blower.

8. The grille of claim 6 , wherein the plate is releasably connected to the trim ring by an attachment mechanism.

9. The grille of claim 6 , wherein the plate is releasably connected to the trim ring by an attachment mechanism and the attachment mechanism comprises a magnet.

10. The grille of claim 6 , wherein the plate defines apertures to allow movement of air through the plate.

11. A grille configured to be connected to a ventilation system comprising a main housing defining an internal region and a blower in the internal region and configured to move air, the grille comprising:
a trim ring having a grille spring for connecting the trim ring to the main housing or the blower, the trim ring defining an aperture through which the air is configured to flow and providing access to the main housing or blower when the trim ring is connected to the main housing or blower; and
a plate configured to releasably connect to the trim ring to cover the aperture.

12. The grille of claim 11 , wherein the trim ring aperture provides access to the grille spring when the trim ring is connected to the main housing or blower.

13. The grille of claim 11 , wherein the plate is releasably connectable to the trim ring by an attachment mechanism.

14. The grille of claim 11 , wherein the plate is releasably connectable to the trim ring by an attachment mechanism and the attachment mechanism comprises a magnet.

15. The grille of claim 11 , wherein the plate defines apertures to allow movement of air through the plate.

16. A ventilation system comprising
a main housing defining an internal region and the main housing configured to be positioned adjacent to a room of a building structure,
a blower in the internal region and configured to draw air out of the room of the building structure, and
a grille configured to at least partially block view of the main housing and the blower, the grille comprising:
a trim ring releasably connectable to the main housing or the blower by a grille spring; and
a plate for releasably connecting to the trim ring

wherein the trim ring defines an aperture through which the air is configured to flow and providing access to the main housing or blower when the trim ring is connected to the main housing or blower.

17. A grille for connection to a ventilation system comprising a main housing defining an internal region and a blower in the internal region and configured to move air, the grille comprising:
a trim ring releasably connectable to the main housing or the blower by a grille spring; and
a plate for releasably connecting to the trim ring;
wherein the trim ring defines an aperture through which the air is configured to flow and providing access to the main housing or blower when the trim ring is connected to the main housing or blower.

18. A grille for connection to a ventilation system comprising a main housing defining an internal region and a blower in the internal region and configured to move air, the grille comprising:
a trim ring having a connection mechanism for connecting the trim ring to the main housing or the blower; and
a plate for releasably connectable to the trim ring;
wherein the trim ring defines an aperture through which the air is configured to flow and provides access to the connection mechanism and the main housing or blower when the trim ring is connected to the main housing or blower.

19. The grille of claim 18 , wherein the connection mechanism is a grille spring.
