Abstract
Abstract A device for supporting patching compounds in its plastic state during the repair of holes in building walls of gypsum board construction. The backing device includes an apertured, foldable plate member which may be inserted through the hole to be patched and then erected so as to cover the hole. The invention is also characterized by a telescoping support member which passes through the aperture in the foldable plate and will retain the plate in position by acting against the plate and the inner surface of the opposing wall.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
A backing device for use in repairing building construction characterized by opposed walls with a space therebetween, said backing device comprising: a foldable plate, said plate including at least two segments joined by hinge means, said plate further being characterized by an aperture therethrough, said aperture being defined with the plate in a substantially planar erected condition; telescoping means, said telescoping means having an extended length in excess of the spacing between the opposed building walls and having a cross-sectional area of sufficient dimension to permit passage of said telescoping means through said plate aperture; and means carried by said telescoping means for engaging said plate whereby said plate may be inserted through a hole in a building wall and erected and said telescoping means thereafter inserted through the plate aperture and into contact with the opposing building walls such that the plate will be held in position over the building wall hole by the engaging means carried by the telescoping means.
Claim 2
Dependent Claim
162 words
A backing device for use in repairing building construction characterized by opposed walls with a space therebetween, said backing device comprising: a foldable plate, said plate including at least two segments joined by hinge means, said plate further being characterized by an aperture therethrough, said aperture being defined with the plate in a substantially planar erected condition; telescoping means, said telescoping means having an extended length in excess of the spacing between the opposed building walls and having a cross-sectional area of sufficient dimension to permit passage of said telescoping means through said plate aperture; and means carried by said telescoping means for engaging said plate whereby said plate may be inserted through a hole in a building wall and erected and said telescoping means thereafter inserted through the plate aperture and into contact with the opposing building walls such that the plate will be held in position over the building wall hole by the engaging means carried by the telescoping means.
Claim 3
Dependent Claim
46 words
The apparatus of claim 1 wherein said foldable plate includes two segments and each of said segments comprises: a planar member having a cut-out in the edge thereof which will be hinged to the segment defining member, said cut-out defining a portion of the plate aperture.
Claim 4
Dependent Claim
39 words
The apparatus of claim 2 wherein said plate segment cut-outs define a circular aperture having a pair of opposed slots extending outwardly therefrom in opposite directions, said slots being commensurate in size and shape with said plate engaging means.
Claim 5
Dependent Claim
28 words
The apparatus of claim 3 further comprising: erecting means connected to each of said plate segments, said erecting means including a flexible member extending between the plate segments.
Claim 6
Dependent Claim
31 words
The apparatus of claim 3 wherein said telescoping means comprises: a first tubular member, said first tubular member supporting said locking means; and means movably supported in said first tubular member.
Claim 7
Dependent Claim
33 words
The apparatus of claim 5 wherein said movably supported means comprises: resilient means coaxial with said first tubular member, said resilient means having a diameter less than that of said first tubular member.
Claim 8
Dependent Claim
12 words
The apparatus of claim 6 wherein said resilient means comprises: a spring.
Claim 9
Dependent Claim
43 words
The apparatus of claim 6 wherein said resilient means further comprises: a second tubular member having an outer diameter less than the inner diameter of said first tubular member, said second tubular member being coupled to said first tubular member by said spring.
Claim 10
Dependent Claim
28 words
The apparatus of claim 7 further comprising: erecting means connected to each of said plate segments, said erecting means including a flexible member extending between the plate segments.
Claim 11
Dependent Claim
17 words
The apparatus of claim 9 wherein said plate segments are each perforated by an array of holes.
