Abstract
Abstract A wall shingle consisting of a profiled panel having at an upper, horizontal edge means for fixing the panel to a wall. At the lower edge, the shingle has means for complementary connecting to a shingle below it so that a run of shingles may be extended upwardly. On the vertical edges the shingle has means for interconnecting with a complementary edge of an adjacent shingle. Conveniently, one edge is of a tongue and other of a groove construction of a particular type. The configuration and shape of the shingles is such that both the vertical and horizontal run of the shingles provides for a continuous airspace between the thus defined wall covering and the wall.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
270 words
A wall covering system providing moisture removal from a wall which comprises: on a wall a run of shingles in a horizontal direction and a run of shingles in vertical direction; each shingle having an exterior face including a face exposed to weather; each shingle having a back side exposed to said wall; a top horizontal edge of said shingle resting on said wall with a plurality of horizontally spaced apart surfaces; clamp means placed on said horizontally spaced apart surfaces on said exterior face thereof; each shingle having bent means spaced away from said wall at said top horizontal edge alternating with said horizontally spaced apart surfaces; each shingle having a bottom horizontal edge having a tab means for lockingly engaging with said clamp means on a top horizontal edge of a next shingle in said run of shingles in said vertical direCtion; vent means at said bottom edge alternating with said tab means whereby said vent means cover superimposed thereover a corresponding vent means on top, horizontal edge of said next shingle in said vertical run; each of said shingles having a first vertical edge having groove means therein; each of said shingles having a second vertical edge having a tongue means; each of said tongue means engaging a groove means on a next, adjacent shingle in said run in horizontal direction; means extending from said groove means whereby said tongue and groove are sealingly engaged with each other; said shingles in said run in said horizontal direction and said run in said vertical direction defining a horizontal and vertical space whereby venting of said space is achieved.

A wall covering system providing moisture removal from a wall which comprises: on a wall a run of shingles in a horizontal direction and a run of shingles in vertical direction; each shingle having an exterior face including a face exposed to weather; each shingle having a back side exposed to said wall; a top horizontal edge of said shingle resting on said wall with a plurality of horizontally spaced apart surfaces; clamp means placed on said horizontally spaced apart surfaces on said exterior face thereof; each shingle having bent means spaced away from said wall at said top horizontal edge alternating with said horizontally spaced apart surfaces; each shingle having a bottom horizontal edge having a tab means for lockingly engaging with said clamp means on a top horizontal edge of a next shingle in said run of shingles in said vertical direCtion; vent means at said bottom edge alternating with said tab means whereby said vent means cover superimposed thereover a corresponding vent means on top, horizontal edge of said next shingle in said vertical run; each of said shingles having a first vertical edge having groove means therein; each of said shingles having a second vertical edge having a tongue means; each of said tongue means engaging a groove means on a next, adjacent shingle in said run in horizontal direction; means extending from said groove means whereby said tongue and groove are sealingly engaged with each other; said shingles in said run in said horizontal direction and said run in said vertical direction defining a horizontal and vertical space whereby venting of said space is achieved.
Claim 3
Dependent Claim
47 words
The wall covering as defined in claim 1 and wherein the clamp means is placed exteriorly on the surface of said shingle which rests on said wall and said clamp means and said shingles are affixed to said wall from said exterior surface by fastening means therefor.
Claim 4
Dependent Claim
51 words
The wall covering as defined in claim 2 and wherein the clamp means have an upper ledge and an upturned lower ledge, said lower ledge being spaced apart from said upper ledge and defining channel means for receiving a resilient, locking tab from said upper, adjacent shingle in said vertical run.
Claim 5
Dependent Claim
45 words
The wall covering as defined in claim 1 and wherein said clamp means and said tab means of each successive shingle in said vertical direction cooperate to provide for attachment of said shingles only to said wall at the top horizontal edge of each shingle.
