Abstract
Abstract A solar heat collecting building block, having top, bottom, front, back and side surfaces, the block having at least one vertical passage extending therethrough from the bottom surface to the top surface, the top surface having an upper portion which protrudes above the plane of the top surface, the bottom surface having a recessed portion for mating receipt of the upper portion of another block, the front surface of the block having at least one transparent member embedded therein to allow solar rays to pass therethrough and strike the interior portions of said block and heat the same.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
122 words
A solar heat collecting building block comprising a cast block of porous heat sink material having top, bottom, front, back and side surfaces, said block having at least one vertical passage extending therethrough from said bottom surface to said top surface, said top surface having an upper portion which dwells generally above the plane of said top surface, said bottom surface having a recessed portion which dwells in a plane recessed from the plane of said bottom surface, said upper portion of one block being capable of matingly being received in said recessed portion of another block, said front surface having at least one transparent member embedded therein to allow solar rays to pass therethrough and strike interior portions of said block.
Claim 2
Dependent Claim
122 words
A solar heat collecting building block comprising a cast block of porous heat sink material having top, bottom, front, back and side surfaces, said block having at least one vertical passage extending therethrough from said bottom surface to said top surface, said top surface having an upper portion which dwells generally above the plane of said top surface, said bottom surface having a recessed portion which dwells in a plane recessed from the plane of said bottom surface, said upper portion of one block being capable of matingly being received in said recessed portion of another block, said front surface having at least one transparent member embedded therein to allow solar rays to pass therethrough and strike interior portions of said block.
Claim 3
Dependent Claim
14 words
The block of claim 1 wherein said block has a plurality of vertical passages.
Claim 4
Dependent Claim
12 words
The block of claim 1 wherein said block is a concrete block.
Claim 5
Dependent Claim
13 words
The block of claim 1 wherein said block is a porous Haydite block.
Claim 6
Dependent Claim
18 words
The block of claim 1 wherein said block has adjacent said back wall, a layer of insulation material.
Claim 7
Dependent Claim
15 words
The building wall of claim 1 wherein said blocks are a dark, heat absorbing color.
Claim 8
Dependent Claim
26 words
The block of claim 2 wherein said vertical passages extend from the recessed area of said bottom surface through the upper portion of said top surface.
Claim 9
Dependent Claim
22 words
The block of claim 2 wherein said block includes a hot air collecting passage, just behind and adjacent to said transparent member.
Claim 10
Dependent Claim
33 words
The block of claim 8 wherein a first transparent member has spaced apart and immediately behind it, a second transparent member, said hot air collecting passage being just behind said second transparent member.
Claim 11
Dependent Claim
118 words
A building wall formed of a plurality of the cast blocks of claim 8 stacked in a tier, said vertical passages of each block being in intercommunication with said vertical passages of other blocks of the same tier, said hot air collecting passage of each block being in intercommunication with said hot air collecting passages of other blocks of the same tier, means connecting said air collecting passage of the top block of said tier to said vertical passages of said top block such that said hot air collecting passages are in intercommunication with said vertical passages, and means to move air into and through said hot air collecting passages and through and out of said vertical passages.
Claim 12
Dependent Claim
61 words
The block of claim 9 wherein said front surface is comprised of first and second faces, said first face being downwardly and outwardly protruding from said top surface and said second face being upwardly and outwardly protruding from said bottom surface so as to meet said first face at approximately a 90° angle, with said first face having said transparent member.
Claim 13
Dependent Claim
37 words
The block of claim 11 wherein the angle between said first and second transparent members and said top and bottom surfaces is approximately 60° so that solar rays will strike perpendicular to said first and second members.
Claim 14
Dependent Claim
20 words
The block of claim 13 wherein said second second face has a layer of insulation material to prevent heat loss.
