Abstract

A mounting fixture for mounting a piece of telecommunications equipment within an underground vault is disclosed. The mounting fixture includes a frame structure configured to be mounted to an upper edge of an open end of a vault. The mounting fixture also includes a can structure for receiving the piece of telecommunications equipment. The can structure includes a closed end, an open end, and a sidewall extending between the closed end and the open end, the can structure being mounted to the frame structure. A cover including a top end and a skirt portion extending downwardly from the top end is slidably received within the can structure, the skirt portion sized to fit around the piece of telecommunications equipment and sized to fit within the sidewall of the can structure, the top end of the cover forming a water tight seal with the top end of the can structure.

Claims

1. An underground mounting fixture for mounting a piece of telecommunications equipment within a vault, the vault defining a closed bottom end positioned underground, an open top end accessible from street level, and a sidewall extending between the bottom end and the top end, the sidewall defining an upper peripheral edge of the open top end, the vault defining an opening for feeding cable into the vault, the mounting fixture comprising:

a frame structure configured to be mounted to the upper edge of the open end of the vault, the frame structure supporting the piece of telecommunications equipment within the vault, the frame structure comprising;

a center frame section including a first end and a second end;

two leg sections, one of the leg sections extending from the first end of the center frame section and the other one of the leg sections extending from the second end of the center frame section, the two leg sections constructed to fit into slots formed around the upper peripheral edge of the vault, each of the leg sections being configured to slidably telescope with respect to the center frame section to vary the size of the frame structure.

2. The mounting fixture according to claim 1, wherein the two legs are slidably received within the slots formed around the upper peripheral edge of the vault.

3. The mounting fixture according to claim 1, wherein the two legs cooperatively define a width of the frame structure, the width of the frame structure corresponding to a width of the vault, wherein the legs are slidable with respect to the center frame section such that the center frame section can be mounted at different locations along the width of the vault.

4. The mounting fixture according to claim 1, wherein the center frame section and the two leg sections include discrete interlocking structures for fixing the size of the frame structure.

5. The mounting fixture according to claim 3, wherein the center frame section and the two leg sections include discrete interlocking structures for fixing the location of the center frame section along the width of the vault.

6. The mounting fixture according to claim 4, wherein the interlocking structures include pin slots.

7. The mounting fixture according to claim 5, wherein the interlocking structures include pin slots.
