Abstract

A wall box includes an enclosure having a base and a cover connected to the base. The base and the cover enclose an interior region. The wall box further includes a plurality of fiber optic adapters mounted to the enclosure. The fiber optic adapters include an inner port positioned inside the interior region and an outer port positioned at an outer surface of the enclosure. A tray stack is mounted within the interior region. The tray stack includes a tray mount pivotally connected to the enclosure. The tray mount includes a top surface and an oppositely disposed bottom surface. A first splice tray mounting area is disposed on the top surface and a second splice tray mounting area is disposed on the bottom surface. A plurality of trays is disposed in the first splice tray mounting area. A tray is disposed in the second splice tray mounting area.

Claims

1. A wall box comprising:

an enclosure having;

a base;

a front cover connected to the base, wherein the base and the front cover cooperate to enclose an interior region of the enclosure;

a plurality of fiber optic adapters mounted to the enclosure, wherein the fiber optic adapters include an inner port positioned inside the interior region and an outer port positioned at an outer surface of the enclosure;

a tray stack mounted within the interior region of the enclosure, the tray stack including;

a tray mount pivotally connected to the enclosure, the tray mount including a top surface and an oppositely disposed bottom surface, wherein a first splice tray mounting area is disposed on the top surface and a second splice tray mounting area is disposed on the bottom surface;

a plurality of trays disposed in the first splice tray mounting area; and

a tray disposed in the second splice tray mounting area.

2. The wall box of claim 1, wherein the tray mount is pivotally connected to the front cover of the enclosure.

3. The wall box of claim 1, wherein each of the plurality of trays disposed in the first splice tray mounting area is a splice tray.

4. The wall box of claim 3, wherein each splice tray includes two splice mounting locations.

5. The wall box of claim 4, wherein a fiber storage region is disposed between the two splice mounting locations.

6. The wall box of claim 5, wherein the fiber storage region includes two spaced apart half spools about which excess fiber can be spooled.

7. The wall box of claim 6, wherein the fiber storage region includes two full spools positioned in an area defined between the two half spools.

8. The wall box of claim 1, wherein the tray disposed in the second splice tray mounting area is a splitter tray having a splitter mounted thereon.

9. A wall box comprising:

an enclosure having;

a base;

a cover pivotally connected to the base, wherein the base and the cover cooperate to enclose an interior region of the enclosure;

a hinge assembly for pivotally connecting the cover to the base, the hinge assembly including at least one pin member and a plurality of hinge portions, each hinge portion having a free end including a hook portion defining an opening that is adapted to selectively receive the at least one pin member, the hook portions defining gaps between adjacent hook portions;

a retention member adapted to retain the pin member in the opening of the hinge portion, the retention member being a resilient member having a first end portion and an oppositely disposed second end portion that selectively flexes about the first end portion, wherein the second end portion blocks at least a portion of the opening in a relaxed position to retain the pin member in the opening, wherein the second end portion of the retention member is generally aligned with a gap defined between two adjacent hook portions; and

a plurality of fiber optic adapters mounted to the enclosure, wherein the fiber optic adapters include an inner port positioned inside the interior region and an outer port positioned at an outer surface of the enclosure.

10. A wall box as claimed in claim 9, wherein the hinge portions are portion is mounted to the cover and the pin member extends along the length of a side of the base between supports that extend outwardly from the side of the base and that support the pin member.

11. A wall box as claimed in claim 10, wherein the pin member is a generally cylindrical member.

12. A wall box as claimed in claim 10, wherein the first end portion of the retention member is mounted to a side of the cover.

13. A wall box as claimed in claim 9, wherein the second end portion of the retention member includes an end surface that is adapted to abut the pin member when the retention member is in the relaxed position.

14. A wall box as claimed in claim 9, further comprising:

a tray stack mounted within the interior region of the enclosure, the tray stack including;

a tray mount pivotally connected to the enclosure, the tray mount including a top surface and an oppositely disposed bottom surface, wherein a first splice tray mounting area is disposed on the top surface and a second splice tray mounting area is disposed on the bottom surface;

a plurality of trays disposed in the first splice tray mounting area; and

a tray disposed in the second splice tray mounting area.

15. The wall box of claim 14, wherein each of the plurality of trays disposed in the first splice tray mounting area is a splice tray.

16. The wall box of claim 15, wherein the tray disposed in the second splice tray mounting area is a splitter tray having a splitter mounted thereon.

17. A wall box comprising:

an enclosure having;

a base;

a cover pivotally connected to the base, wherein the base and the cover cooperate to enclose an interior region of the enclosure;

a plurality of fiber optic adapters mounted to the enclosure, wherein the fiber optic adapters include an inner port positioned inside the interior region and an outer port positioned at an outer surface of the enclosure;

a tray stack mounted within the interior region of the enclosure, the tray stack including;

a tray mount pivotally connected to the enclosure, the tray mount including a top surface and an oppositely disposed bottom surface, wherein a first splice tray mounting area is disposed on the top surface and a second splice tray mounting area is disposed on the bottom surface;

a plurality of trays disposed in the first splice tray mounting area; and

a tray disposed in the second splice tray mounting area;

a hinge assembly for pivotally connecting the cover to the base, the hinge assembly including at least one pin member and at least one hinge portion, the hinge portion having a free end defining an opening that is adapted to selectively receive the pin member; and

a retention member adapted to retain the pin member in the opening of the hinge portion, the retention member being a resilient member having a first end portion and an oppositely disposed second end portion that selectively flexes about the first end portion, wherein the second end portion blocks at least a portion of the opening in a relaxed position to retain the pin member in the opening.

18. The wall box of claim 17, wherein each of the plurality of trays disposed in the first splice tray mounting area is a splice tray.
