Abstract

A wall-mounted enclosure having a standard forward-facing opening but also having an expanded enclosure behind the opening. The opening allows the use of conventional prior art components (such as cover plates). The expanded enclosure allows a more generous bend radius for the creation of a service loop in a fiber optic cable or similar component.

First claim

Having described our invention, we claim:

1. An expanded electrical box configured to provide an enlarged service loop for a cable, comprising:
(a) a mounting wall;
(b) a forward wall;
(c) a two-gang opening in said forward wall;
(d) said two-gang opening being bounded by a coaming extending forward from said forward wall;
(e) wherein a width of said two-gang opening is between 3.75 and 4.50 inches;
(f) wherein a height of said two-gang opening is between 3.75 and 4.25 inches;
(g) an expanded enclosure behind said forward wall, wherein said expanded enclosure is larger than said two-gang opening;
(h) wherein said expanded enclosure has a height of at least 5.25 inches;
(i) wherein said expanded enclosure has a width of at least 5.25 inches; and
(j) a cable opening leading into said expanded enclosure.

2. The expanded electrical box as recited in claim 1 wherein said coaming provides a suitable standoff distance for installing dry wall forward of said forward wall.

3. The expanded electrical box as recited in claim 1 , further comprising a first nail mount with a first nail and a second nail mount with a second nail.

4. The expanded electrical box as recited in claim 1 , wherein said cable opening includes a cable clamp.

5. The expanded electrical box as recited in claim 1 , wherein said expanded enclosure includes four side walls and a rear wall.

6. The expanded electrical box as recited in claim 1 , wherein said expanded enclosure includes a circular perimeter and a rear wall.

7. The expanded electrical box as recited in claim 6 , wherein said coaming provides a suitable standoff distance for installing dry wall forward of said forward wall.

8. The expanded electrical box as recited in claim 6 , further comprising a first nail mount with a first nail and a second nail mount with a second nail.

9. The expanded electrical box as recited in claim 6 , wherein said cable opening is located in a position that is approximately tangential to said circular perimeter.

10. The expanded electrical box as recited in claim 9 wherein said coaming provides a suitable standoff distance for installing dry wall forward of said forward wall.

11. An expanded electrical box configured to provide an enlarged service loop for a cable, comprising:
(a) a mounting wall;
(b) a forward wall;
(c) a two-gang opening in said forward wall;
(d) said two-gang opening including a protrusion extending forward from said forward wall;
(e) wherein a width of said two-gang opening is between 3.75 and 4.50 inches;
(f) wherein a height of said two-gang opening is between 3.75 and 4.25 inches;
(g) an expanded enclosure behind said forward wall, wherein said expanded enclosure is larger than said two-gang opening;
(h) wherein said expanded enclosure has a height of at least 5.25 inches;
(i) wherein said expanded enclosure has a width of at least 5.25 inches; and
(j) a cable opening leading into said expanded enclosure.

12. The expanded electrical box as recited in claim 11 wherein said protrusion extending forward from said forward wall provides a suitable standoff distance for installing dry wall forward of said forward wall.

13. The expanded electrical box as recited in claim 11 , further comprising a first nail mount with a first nail and a second nail mount with a second nail.

14. The expanded electrical box as recited in claim 11 , wherein said cable opening includes a cable clamp.

15. The expanded electrical box as recited in claim 11 , wherein said expanded enclosure includes four side walls and a rear wall.

16. The expanded electrical box as recited in claim 11 , wherein said expanded enclosure includes a circular perimeter and a rear wall.

17. The expanded electrical box as recited in claim 16 , wherein said protrusion extending forward from said forward wall provides a suitable standoff distance for installing dry wall forward of said forward wall.

18. The expanded electrical box as recited in claim 16 , further comprising a first nail mount with a first nail and a second nail mount with a second nail.

19. The expanded electrical box as recited in claim 16 , wherein said cable opening is located in a position that is approximately tangential to said circular perimeter.

20. The expanded electrical box as recited in claim 19 wherein said protrusion extending forward from said forward wall provides a suitable standoff distance for installing dry wall forward of said forward wall.
