Abstract
Abstract A reflector for mounting above a heating pipe is elongated and in transverse direction subdivided in three sections each of which is arcuately curved in the transverse direction. The center of curvature of the middle section coincides with the vertical symmetry plane of the reflector; the center of curvature of the outer flanking sections are laterally offset and vertically downwardly spaced relative to the center of curvature of the middle section.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
A reflector, particularly for mounting above a heating pipe to reflect heat radiated upwardly by the pipe, comprising an elongated sheet-material reflector body having at least three parallel longitudinally extending concave sections each of which is arcuately curved in transverse direction; each of said arcuately curved sections having a center of curvature, the center of curvature of a center one of said sections being located in a vertical longitudinal plane of symmetry of said reflector body; and the centers of curvature of the sections which flank said center section being laterally spaced from said vertical plane in mutually opposite direction and being spaced from the center of curvature of said center section in a direction away from the center section.
Claim 2
Dependent Claim
120 words
A reflector, particularly for mounting above a heating pipe to reflect heat radiated upwardly by the pipe, comprising an elongated sheet-material reflector body having at least three parallel longitudinally extending concave sections each of which is arcuately curved in transverse direction; each of said arcuately curved sections having a center of curvature, the center of curvature of a center one of said sections being located in a vertical longitudinal plane of symmetry of said reflector body; and the centers of curvature of the sections which flank said center section being laterally spaced from said vertical plane in mutually opposite direction and being spaced from the center of curvature of said center section in a direction away from the center section.
Claim 3
Dependent Claim
41 words
A reflector as defined in claim 1, wherein said centers of curvature of the flanking sections are spaced from said vertical plane by identical distances and are also spaced from said center of curvature of said center section by identical distances.
Claim 4
Dependent Claim
28 words
A reflector as defined in claim 1, said sheet material of said body having longitudinally extending edge portions which are shaped to form hollow, tubular circumferentially incomplete beads.
Claim 5
Dependent Claim
31 words
A reflector as defined in claim 3; further comprising an arcuate sheet material member above said reflector body and having longitudinal edges which extend into and are retained in, said beads.
Claim 6
Dependent Claim
19 words
A reflector as defined in claim 3; further comprising mounting means for mounting said reflector body on a pipe.
Claim 7
Dependent Claim
198 words
A reflector particularly for mounting above a heating pipe to reflect heat radiated upwardly by the pipe, comprising an elongated sheet-material reflector body having at least three parallel longitudinally extending sections each of which is arcuately curved in transverse direction; each of said arcuately curved sections having a center of curvature, the center of curvature of a center one of said sections being located in a vertical longitudinal plane of symmetry of said reflector body; the centers of curvature of the sections which flank said center section being laterally spaced from said vertical plane in mutually opposite direction and being spaced from the center of curvature of said center section in a direction away from the center section; said sheet material of said body having longitudinally extending edge portions which are shaped to form hollow, tubular circumferentially incomplete beads; mounting means for mounting said reflector body on a pipe, said mounting means comprising a mounting structure of elastically yieldable sheet material having a part-circular center clamping portion adapted to at least partly encircle a pipe, and a pair of arms projecting at an angle from said center portion and inclined upwardly relatively thereto from a lower part thereof.
Claim 8
Dependent Claim
198 words
A reflector particularly for mounting above a heating pipe to reflect heat radiated upwardly by the pipe, comprising an elongated sheet-material reflector body having at least three parallel longitudinally extending sections each of which is arcuately curved in transverse direction; each of said arcuately curved sections having a center of curvature, the center of curvature of a center one of said sections being located in a vertical longitudinal plane of symmetry of said reflector body; the centers of curvature of the sections which flank said center section being laterally spaced from said vertical plane in mutually opposite direction and being spaced from the center of curvature of said center section in a direction away from the center section; said sheet material of said body having longitudinally extending edge portions which are shaped to form hollow, tubular circumferentially incomplete beads; mounting means for mounting said reflector body on a pipe, said mounting means comprising a mounting structure of elastically yieldable sheet material having a part-circular center clamping portion adapted to at least partly encircle a pipe, and a pair of arms projecting at an angle from said center portion and inclined upwardly relatively thereto from a lower part thereof.
Claim 9
Dependent Claim
17 words
A reflector as defined in claim 6, said sheet material of said mounting structure being spring steel.
Claim 10
Dependent Claim
24 words
A reflector as defined in claim 6, said center clamping portion being dimensioned to embrace a pipe over about three-quarters of the pipe circumference.
Claim 11
Dependent Claim
49 words
A reflector as defined in claim 6, said arms including an angle of between about 10° and 50° with a straight line connecting the centers of said hollow tubular beads, and said arms having free ends shaped to arcuate form so as to embrace and retain the respective beads.
