Abstract
Abstract The invention provides a solar heating arrangement which has a plurality of substantially hollow elongate members with at least one fluid passage way therein, a plurality of substantially hollow connecting members each adapted to interlock one with the other, each connecting member being adapted so as to interlock with a respective elongate member at each end thereof, the connecting members and the elongate members being interlocked to form a heating arrangement which, when in use, has fluid flowing through it.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
174 words
For use in a heating arrangement which in use has fluid flowing therethrough, in combination: (i) at least one tubular connecting member open at each of its ends and having a through passage, said connecting member having its internal cross-section circular at one of its ends, said connecting member having its external cross-section circular at the other of its ends, said external cross-section being of less diameter than said internal cross-section whereby a plurality of said tubular connecting members may be assembled serially by engagement of an end of each into an end of the next, each connecting member having a portion projecting radially therefrom along part of its length, said projecting portion defining a rectangular passage opening at one end to the exterior of the connecting member and opening at the other end into the through passage of the connecting member, and (ii) at least one substantially hollow elongate member having at least one end thereof a rectangular cross-section of such dimensions as to fit within the rectangular passage of said projecting portion.
Claim 2
Dependent Claim
174 words
For use in a heating arrangement which in use has fluid flowing therethrough, in combination: (i) at least one tubular connecting member open at each of its ends and having a through passage, said connecting member having its internal cross-section circular at one of its ends, said connecting member having its external cross-section circular at the other of its ends, said external cross-section being of less diameter than said internal cross-section whereby a plurality of said tubular connecting members may be assembled serially by engagement of an end of each into an end of the next, each connecting member having a portion projecting radially therefrom along part of its length, said projecting portion defining a rectangular passage opening at one end to the exterior of the connecting member and opening at the other end into the through passage of the connecting member, and (ii) at least one substantially hollow elongate member having at least one end thereof a rectangular cross-section of such dimensions as to fit within the rectangular passage of said projecting portion.
Claim 3
Dependent Claim
25 words
The combination of claim 1 wherein said hollow elongate member includes at least one internal longitudinal wall defining a plurality of fluid flow passages therein.
Claim 4
Dependent Claim
22 words
The combination of claim 1 wherein each connecting member is an integral moulding, and wherein each elongate member is an integral moulding.
Claim 5
Dependent Claim
171 words
A heating arrangement comprising, in combination: (a) an assembly formed from two series of the connecting members set forth in claim 1, the members of each series having said other end of less diameter of one said member inserted in said one end of another of said members, and a plurality of elongate members as set forth in claim 1, each of said elongate members having a first said end of rectangular cross-section engaged within said rectangular passage of a member of one of said series of connecting members, each of said elongate members having a second said end of rectangular cross-section engaged within said rectangular passage of a member of the other of said series of connecting members, (b) an open-ended recessed housing within which said assembly is disposed, (c) a sheet of at least semi-transparent material mounted over the open end of said housing and above said assembly, (d) means providing a fluid inlet and a fluid outlet for said housing connected respectively to said series of connecting members.
Claim 6
Dependent Claim
22 words
The heating arrangement of claim 4 further comprising a layer of thermally insulating material disposed within said housing and beneath said assembly.
Claim 7
Dependent Claim
30 words
In combination, (i) the heating arrangement of claim 4 (ii) a thermally insulated fluid reservoir, and (iii) means connecting said fluid inlet and said fluid outlet to said fluid reservoir.
Claim 8
Dependent Claim
26 words
In combination: (i) a plurality of the heating arrangements of claim 3, and (ii) means interconnecting said assemblies to provide a continuous fluid flow path therethrough.
