Abstract

A mud ring assembly for supporting an electrical device including a base member configured to be coupled to a junction box having a first corner and a second corner. The base member has a perimeter configured to extend around the first corner and not reach the second corner so that the base member is not positioned above the second corner. The mud ring assembly also includes a movable member configured to support the electrical device. The movable member is pivotably connected to the base member and pivotable relative to the base member between a closed position in which a back of the electrical device is enclosed in the junction box and an open position permitting access to the back of the electrical device. The movable member is couplable at a second portion of the junction box to selectively secure the movable member in the closed position.

First claim

What is claimed is:

1. A mud ring assembly for supporting an electrical device, the mud ring assembly comprising:
a base member configured to be coupled to a junction box, the base member configured to extend around only a portion of the junction box perimeter; and
a movable member configured to support the electrical device, the movable member being pivotably connected to the base member and pivotable relative to the base member between a closed position in which a back of the electrical device is enclosed in the junction box and an open position in which the back of the electrical device is accessible, the movable member being securable in the closed position.

2. The mud ring assembly of claim 1 , wherein the base member is configured to extend around at least two edges of an opening of the junction box.

3. The mud ring assembly of claim 1 , wherein the base member includes a slot configured to receive a fastener for coupling the base member to the junction box.

4. The mud ring assembly of claim 1 , wherein the movable member includes a projection movable between a bent position and an unbent position, the projection configured to secure the movable member against uncoupling from the base member.

5. The mud ring assembly of claim 1 , wherein the junction box includes an edge forming the perimeter, the base member configured to expose at least a portion of the edge when the movable member is in the open position.

6. The mud ring assembly of claim 1 , wherein the movable member is also supported for tilting movement relative to the base member, wherein closing the movable member requires tilting the movable member away from an orientation that is squarely aligned with the base member and pivoting the movable member to permit an opening of the movable member to pass over a fastener.

7. The mud ring assembly of claim 6 , wherein the opening of the movable member has a keyhole shape.

8. The mud ring assembly of claim 1 , wherein a portion of a peripheral edge of the movable member is inclined at an acute angle relative to an adjacent portion of the peripheral edge.

9. The mud ring assembly of claim 1 , wherein a peripheral edge of the base member includes a flange, wherein a complementary portion of a peripheral edge of the movable member includes a flange, the flange of the base member and the flange of the movable member forming a substantially continuous perimeter when the movable member is in a closed position.

10. A mud ring assembly comprising:
a base member having a surface, the base member is configured to be coupled to a junction box having an opening; and
a movable member configured to support the electrical device, the movable member being pivotably connected to the base member and pivotable relative to the base member between a closed position in which a back of the electrical device is enclosed in the junction box and an open position in which the back of the electrical device is accessible, the movable member being also supported for tilting movement relative to the base member, securing the movable member against the base member requires tilting the movable member away from an orientation that is squarely aligned with the base member and pivoting the movable member to permit an opening of the movable member to pass over a fastener.

11. The mud ring assembly of claim 10 , wherein the base member is configured to extend around at least two edges of an opening of the junction box.

12. The mud ring assembly of claim 10 , wherein the base member includes a slot configured to receive a fastener for coupling the base member to the junction box.

13. The mud ring assembly of claim 10 , wherein the movable member includes a projection movable between a bent position and an unbent position, the projection configured to secure the movable member against uncoupling from the base member.

14. The mud ring assembly of claim 10 , wherein the junction box includes an edge forming the perimeter, the base member configured to expose at least a portion of the edge when the movable member is in the open position.

15. The mud ring assembly of claim 10 , wherein the base member is configured to extend along a portion of a perimeter of the opening of the junction box.

16. The mud ring assembly of claim 10 , wherein the opening of the movable member has a keyhole shape.

17. The mud ring assembly of claim 10 , wherein a portion of a peripheral edge of the movable member is inclined at an acute angle relative to an adjacent portion of the peripheral edge.

18. The mud ring assembly of claim 10 , wherein a peripheral edge of the base member includes a flange, wherein a complementary portion of a peripheral edge of the movable member includes a flange, the flange of the base member and the flange of the movable member forming a substantially continuous perimeter when the movable member is in a closed position.
