Abstract
Abstract The invention consists in an immersible solar heat collecting means capable of being laid at the bottom of a pool where it can be walked upon. The substantially laminar portions of the collector each includes a surface of higher light absorbence than the other side thereof so that by folding or otherwise overlapping and rearranging the various portions a different number of higher light absorbence surfaces can be presented to the sun to heat the water at any particular time. Such an apparatus makes possible the controlled solar heating of a pool.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
194 words
A water immersible solar heat collecting means comprising an array of substantially laminar members with one side having a higher light absorbence than the other, each of which laminar member is of a configuration and sufficient density to lie flat on the bottom of a water filled swimming pool, hinge means connecting at least one edge of each member to an edge of another member to provide a unitary structure capable of being laid out in a flat position with the higher light absorbence surface of all of said members facing upwardly and of being rearranged by folding said members about said hinge means to selectively vary the number of members having their higher light absorbence surface facing upwardly, at least one of said laminar members has two edges each connected by a said hinge means to an edge of different laminar members, wherein two of said edges are normal with respect to each other, wherein there are four laminar members two of which have one said hinge means and two of which have two said hinge means one of the hinge means being located between the two laminar members having two hinge means.
Claim 2
Dependent Claim
194 words
A water immersible solar heat collecting means comprising an array of substantially laminar members with one side having a higher light absorbence than the other, each of which laminar member is of a configuration and sufficient density to lie flat on the bottom of a water filled swimming pool, hinge means connecting at least one edge of each member to an edge of another member to provide a unitary structure capable of being laid out in a flat position with the higher light absorbence surface of all of said members facing upwardly and of being rearranged by folding said members about said hinge means to selectively vary the number of members having their higher light absorbence surface facing upwardly, at least one of said laminar members has two edges each connected by a said hinge means to an edge of different laminar members, wherein two of said edges are normal with respect to each other, wherein there are four laminar members two of which have one said hinge means and two of which have two said hinge means one of the hinge means being located between the two laminar members having two hinge means.
Claim 3
Dependent Claim
14 words
A collecting means as claimed in claim 1 wherein said edges are straight edges.
Claim 4
Dependent Claim
15 words
A collecting means as claimed in claim 2 wherein each laminar member is substantially rectangular.
Claim 5
Dependent Claim
18 words
A collecting means as claimed in claim 1 wherein said members are substantially identical in size and configuration.
Claim 6
Dependent Claim
36 words
A collecting means as claimed in claim 1 wherein each laminar member is substantially rigid and said hinge means provide for folding said members in both directions so as to allow either overlapping or underlapping thereof.
Claim 7
Dependent Claim
33 words
A collecting means as claimed in claim 5 wherein each said laminar member includes a layer of metal and a layer of flexible plastic material, said plastic material serving as said hinge means.
Claim 8
Dependent Claim
33 words
A collecting means as claimed in claim 6 wherein each laminar member is comprised of a layer of metal covered on both sides with a layer of flexible plastic material of vinyl chloride.
Claim 9
Dependent Claim
26 words
A collecting means as claimed in claim 7 wherein said side having a higher light absorbence is colored black and said other side is colored aqua.
