Abstract

Abstract Apparatus is disclosed for repairing holes in hollow walls such as wallboard or sheetrock or the like. The apparatus comprises an interior plate having a positioner guide thereon so that when the interior plate is inserted through the hole to be repaired the positioner guide may rest on one side of said hole as the interior plate abuts the interior surface of the wall and covers the hole. A surface plate is sized to fit securely and firmly into the hole and has retainer clips at each side thereof to retain and position the surface of the surface plate flush with the surface of the wall. A positioner wire extends through both the interior plate and the surface plate and allows the interior plate to be pushed through the wall opening and then to be pulled back into proper position relative to the surface plate. An attaching bolt is extended through the surface plate and engages a nut fixed to the interior plate to securely fasten the surface plate in the hole.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 178 words
A device for attachment to sheetrock or the like wall boards for repairing holes therein or attaching fixtures thereto comprising: a surface plate having an area approximately that of the area of an opening in said sheetrock, and having an attaching bolt hole and a positioner hole extending completely therethrough; retainer means carried by said surface plate and extending laterally outwardly therefrom; an interior plate having an area larger than the area of said surface plate and said opening in the sheetrock, and having an attaching bolt hole and a positioner hole extending completely therethrough; and a threaded nut securely attached to said interior plate and aligned with said attaching bolt hole; positioner guide means carried by said interior plate; an elongated flexible member extending through said positioner holes in said surface plate and said interior plate and having anchoring means at each end thereof, so that said plates may be separated and moved along said flexible member without sliding off said member; and, an attaching bolt for passage through the bolt holes to engage said threaded nut.
Claim 2
Independent Claim 178 words
A device for attachment to sheetrock or the like wall boards for repairing holes therein or attaching fixtures thereto comprising: a surface plate having an area approximately that of the area of an opening in said sheetrock, and having an attaching bolt hole and a positioner hole extending completely therethrough; retainer means carried by said surface plate and extending laterally outwardly therefrom; an interior plate having an area larger than the area of said surface plate and said opening in the sheetrock, and having an attaching bolt hole and a positioner hole extending completely therethrough; and a threaded nut securely attached to said interior plate and aligned with said attaching bolt hole; positioner guide means carried by said interior plate; an elongated flexible member extending through said positioner holes in said surface plate and said interior plate and having anchoring means at each end thereof, so that said plates may be separated and moved along said flexible member without sliding off said member; and, an attaching bolt for passage through the bolt holes to engage said threaded nut.
