Abstract

A lightweight tubular housing open at both ends is specially constructed so as to be buried in the earth to almost its full height and yet withstand thrust forces of fill material. For this purpose the housing has outwardly curved side walls, it is tapered to a larger dimension toward the bottom, and its walls have an increasing outward curvature toward the bottom. The front wall of the housing is of less height than the rear wall to provide front access to the equipment. An inverted cup-shaped cover closes the upper open end of the housing and has a hinged connection that allows it to be opened or to be readily disconnected. To allow the housing to be buried throughout most of its height if necessary as well as to provide a large area at the lower portion of the housing for storing excess length of cable and for adjusting the cable laterally for convenient hook-up to the equipment, the front access opening preferably extends only a minimum distance down from the top relative to the over-all height of the enclosure.

Claims

1. An enclosure for equipment comprising

(a) a vertical tubular housing having an inner area defined by surrounding front, rear and side walls,

(b) the lower end of said housing being open for receiving cable extending up from the ground,

(c) the upper end of said housing being open throughout its entire cross sectional area,

(d) a substantially straight wall portion at the upper end of said rear wall arranged to support equipment to be connected to the cable,

(e) said front wall being of less height than said rear wall to provide a front access opeing to the equipment supported on the upper portion of said rear wall,

(f) the walls of said housing being curved outwardly at a progressively smaller radius toward the bottom,

(g) and a cover having a downwardly extending flange and arranged to cover said upper open end including said front wall opening.

2. The enclosure of claim 1 wherein said housing has inset means at the upper portion of said front wall forming a shoulder arranged to provide a seat for the bottom edge of said cover in the mounted position of said cover on said housing.

3. The enclosure of claim 1 wherein said straight wall portion of said rear wall is offset inwardly to provide a space for equipment fastening means between said straight wall portion and said cover.

4. The enclosure of claim 1 wherein said side walls have angled top edges extending upwardly from the bottom of said access opening to the top of said rear wall.

5. The enclosure of claim 1 wherein said housing is tapered to a larger dimension toward the bottom.

6. The enclosure of claim 5 including an outwardly turned flange at the bottom of said housing arranged either to support said housing on a surface pad or to anchor said housing in the ground when said housing is partially buried.

7. An enclosure for equipment comprising

(a) a vertical tubular housing having an inner area defined by surrounding front, rear and side walls,

(b) the lower end of said housing being open for receiving cable extending up from the ground,

(c) the upper end of said housing being open throughout its entire cross sectional area,

(d) a substantially straight wall portion at the upper end of said rear wall arranged to support equipment to be connected to the cable,

(e) said front wall being of less height than said rear wall to provide a front access opening to the equipment supported on the upper portion of said rear wall,

(f) said front access opening extending down less than one-half the height of said housing,

(g) and a cover having a downwardly extending flange and arranged to cover said upper open end including said front wall opening, the walls of said housing being curved outwardly at a progressively smaller radius toward the bottom.

8. The enclosure of claim 7 including an outwardly turned flange at the bottom of said housing arranged either to support said housing on a surface pad or to anchor said housing in the ground when said housing is partially buried.
