Abstract
Abstract An insulated pipe enclosure for use above ground includes opposed, internally insulated, generally C-shaped, thin-walled base and cover sections, which are interconnected end-to-end by overlapping one section with the next, each cover and base being interconnected by screws in flanges extending outwardly from each side of the cover and base. The pipes in the enclosure rest on vertically extending supports, which are embedded in the insulation of the base sections.

Total Claims: 9
Claim 1
Independent Claim
156 words
A pipe enclosure for use above ground comprising: (a) an elongated casing, including (i) a generally C-shaped, upwardly opening base defined by a bottom wall, upwardly and outwardly extending side walls, and outwardly extending flanges having downwardly turned edges on upper free ends of said side walls, and (ii) a generally C-shaped, downwardly opening cover defined by a top wall, outwardly and downwardly extending side walls, and outwardly extending flanges having downwardly turned edges on lower free ends of said side walls for engaging the correspondingly shaped flanges on said base to define a closed casing; (b) means for releasably interconnecting said base and cover; (c) insulation on the interior of said base and said cover, and (d) first support means having a U-shaped cross section and supported by the insulation in said base and spaced from said base for supporting at least one pipe in said casing and spaced from said casing by said insulation.
Claim 2
Dependent Claim
156 words
A pipe enclosure for use above ground comprising: (a) an elongated casing, including (i) a generally C-shaped, upwardly opening base defined by a bottom wall, upwardly and outwardly extending side walls, and outwardly extending flanges having downwardly turned edges on upper free ends of said side walls, and (ii) a generally C-shaped, downwardly opening cover defined by a top wall, outwardly and downwardly extending side walls, and outwardly extending flanges having downwardly turned edges on lower free ends of said side walls for engaging the correspondingly shaped flanges on said base to define a closed casing; (b) means for releasably interconnecting said base and cover; (c) insulation on the interior of said base and said cover, and (d) first support means having a U-shaped cross section and supported by the insulation in said base and spaced from said base for supporting at least one pipe in said casing and spaced from said casing by said insulation.
Claim 3
Dependent Claim
37 words
A pipe enclosure according to claim 1, wherein said base and cover are metal, and wherein said base and cover are adapted to be connected end-to-end with other bases and covers by overlapping adjacent bases and covers.
Claim 4
Dependent Claim
35 words
