Abstract

A mud ring supports an electrical device with respect to a junction box. The mud ring includes a base member configured to be coupled to the junction box; a cover coupled to the base member for movement between a first position and a second position, the cover including an opening; and an insert positioned in the opening and supported for movement relative to the cover, the insert configured to be coupled to the electrical device.

First claim

What is claimed is:

1. A mud ring for supporting an electrical device with respect to a junction box, the mud ring comprising:
a base member configured to be coupled to the junction box;
a cover coupled to the base member for movement between a first position and a second position, the cover including an opening;
an insert positioned in the opening and supported for movement relative to the cover, the insert configured to be coupled to the electrical device;
an actuator coupled between the insert and the cover for driving the insert to move relative to the cover,
wherein the insert includes a first portion to limit movement of the insert in a first direction relative to the cover and a second portion to limit movement of the insert in a second direction opposite the first direction.

2. The mud ring of claim 1 , further comprising a latch for selectively securing the cover against movement relative to the base member.

3. The mud ring of claim 2 , wherein the latch is movable between a latched position and an unlatched position, and, when the latch is in the latched position, the latch engages a fastener to secure the cover against movement relative to the base member.

4. The mud ring of claim 1 , wherein the base member is configured to extend along a portion of a perimeter of the junction box, a first portion of the base member secured to one corner of the junction box and a second portion of the base member positioned adjacent an opposite corner of the junction box.

5. The mud ring of claim 1 , wherein the base member has a substantially L-shaped profile.

6. The mud ring of claim 1 , wherein the base member has a substantially C-shaped profile.

7. The mud ring of claim 1 , wherein the base member is capable of being secured to the junction box in a first configuration and a second configuration.

8. The mud ring of claim 1 , wherein the base member has a profile that extends around fastener mounting portions of the junction box.

9. The mud ring of claim 1 , wherein the actuator extends through a first flange in the insert and a second flange in the cover.

10. The mud ring of claim 1 , wherein the actuator includes a threaded fastener supported for free rotation relative to one of the insert and the cover, rotation of the threaded fastener causing the insert to translate relative to the cover in a direction normal to a plane of the cover.

11. A mud ring for supporting an electrical device with respect to an electrical box, the mud ring comprising:
a base member configured to be coupled to an electrical box via a fastener;
a cover coupled to the base member for pivoting movement about a pivot axis between a closed position and an open position, the cover permitting access to an interior portion the electrical box in the open position, the cover including an opening;
an insert positioned in the opening and supported for movement relative to the cover in a direction oriented perpendicular to the pivot axis, the insert configured to be coupled to the electrical device; and
a latch for selectively securing the cover against movement relative to the base member,
wherein the latch is rotatable between a latched position and an unlatched position, and, when the latch is in the latched position, the latch engages the fastener to secure the cover against movement relative to the base member.

12. The mud ring of claim 11 , wherein the latch includes an arm pivotally supporting on the cover and a slot for receiving the fastener.

13. The mud ring of claim 11 , wherein the base member is configured to extend along a portion of a perimeter of the electrical box, a first portion of the base member secured to one corner of the electrical box and a second portion of the base member positioned adjacent an opposite corner of the electrical box.

14. The mud ring of claim 11 , wherein the base member is configured to be coupled to the electrical box by a plurality of fasteners, wherein the plurality of fasteners may engage the base member in a plurality of configurations.

15. The mud ring of claim 11 , wherein the base member has a profile that extends around fastener mounting portions of the electrical box.

16. The mud ring of claim 11 , wherein the base member has a substantially L-shaped profile.

17. The mud ring of claim 11 , wherein the base member has a substantially C-shaped profile.

18. The mud ring of claim 11 , further comprising an actuator coupled between the insert and the cover for driving the insert to move relative to the cover.

19. The mud ring of claim 18 , wherein the actuator includes a threaded fastener supported for free rotation relative to one of the insert and the cover, rotation of the threaded fastener causing the insert to translate relative to the cover in a direction normal to a plane of the cover.

20. The mud ring of claim 3 , wherein the latch is rotatable between the latched position and the unlatched position.
