Abstract
Abstract A backing plate (11) is positioned to cover a hole (13) on a backside (14) of a wall (15). Integral with the backing plate (11) is a fastener (21) which protrudes through the hole (13) in the direction of a frontside (16) of the wall (15). The hole (13) is filled from the frontside (16) with a patching material before a dam (27) is positioned over the hole (13). The dam (27) accommodates the fastener (21) so that fastener (21) can be tightened for exerting pressure on the patching material between the dam (27) and the backing plate (11).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
236 words
A method for repairing a hole in a front surface of a wall without having access to the back surface thereof, said method comprising steps of: inserting a backing means through the hole to the back side of the wall, and thereafter controlling the position of said backing means from the front side of the wall to cover a portion of the backside of said wall with said backing means, said covered backside portion substantially encompassing said hole, said backing means having at least one adjustable fastening means attached thereto and protruding through said hole when said backing means covers said backside portion of said wall which is used for controlling the position of the backing means; filling said hole in said wall with a patching material while holding said backing means in a position covering said backside portion of said wall with said fastening means from the front side of said wall; thereafter positioning a dam means over a portion of a front side of said wall, said front-side portion substantially encompassing said hole, said dam means being adapted to receive said fastening means protruding through said hole; thereafter tightening said fastening means of said backing means against said dam means so as to exert pressure on said patching material between said dam means and said backing means; and, removing said fastening means and said dam means from said front side portion of said wall.
Claim 2
Independent Claim
236 words
A method for repairing a hole in a front surface of a wall without having access to the back surface thereof, said method comprising steps of: inserting a backing means through the hole to the back side of the wall, and thereafter controlling the position of said backing means from the front side of the wall to cover a portion of the backside of said wall with said backing means, said covered backside portion substantially encompassing said hole, said backing means having at least one adjustable fastening means attached thereto and protruding through said hole when said backing means covers said backside portion of said wall which is used for controlling the position of the backing means; filling said hole in said wall with a patching material while holding said backing means in a position covering said backside portion of said wall with said fastening means from the front side of said wall; thereafter positioning a dam means over a portion of a front side of said wall, said front-side portion substantially encompassing said hole, said dam means being adapted to receive said fastening means protruding through said hole; thereafter tightening said fastening means of said backing means against said dam means so as to exert pressure on said patching material between said dam means and said backing means; and, removing said fastening means and said dam means from said front side portion of said wall.
Claim 3
Dependent Claim
33 words
The method of claim 1, further comprising the step of: filling with said patching material a hole left by the removal of said fastening means from said front side portion of said wall.
Claim 4
Dependent Claim
44 words
The method of claim 1, further comprising the steps of: drilling at least one hole in said backing means, said hole in said backing means being adapted to receive said fastening means; and inserting said fastening means into said hole in said backing means.
Claim 5
Dependent Claim
230 words
Apparatus for repairing holes in a wall, said apparatus comprising: backing means for being inserted from the frontside of the wall through a hole in the wall to the backside thereof, and thereafter for covering a portion of the backside of said wall, said covered backside portion substantially encompassing said hole; adjustable fastening means having an enlarged head and a shank portion and means engageable with said backing means, said adjustable fastening means being adapted to protrude through said hole in said wall when said backing means covers said backside portion for allowing one to control the position of the backing means from the frontside of the wall while said hole is filled with patching materials from the frontside of said wall; dam means for thereafter covering a portion of the front-side of said wall, said frontside portion substantially encompassing said hole, and for coming into engagement with said fastening means as said fastening means protrudes through said patching materials in said hole for maintaining a fixed distance between said backing means and said dam means to thereby hold said patching material in said hole; said dam means having a slot therein extending from a side edge of said dam means to a point near its center, said slot being of a width to allow passage therethrough of said shank of said fastening means, but not said enlarged head thereof.
Claim 6
Dependent Claim
230 words
Apparatus for repairing holes in a wall, said apparatus comprising: backing means for being inserted from the frontside of the wall through a hole in the wall to the backside thereof, and thereafter for covering a portion of the backside of said wall, said covered backside portion substantially encompassing said hole; adjustable fastening means having an enlarged head and a shank portion and means engageable with said backing means, said adjustable fastening means being adapted to protrude through said hole in said wall when said backing means covers said backside portion for allowing one to control the position of the backing means from the frontside of the wall while said hole is filled with patching materials from the frontside of said wall; dam means for thereafter covering a portion of the front-side of said wall, said frontside portion substantially encompassing said hole, and for coming into engagement with said fastening means as said fastening means protrudes through said patching materials in said hole for maintaining a fixed distance between said backing means and said dam means to thereby hold said patching material in said hole; said dam means having a slot therein extending from a side edge of said dam means to a point near its center, said slot being of a width to allow passage therethrough of said shank of said fastening means, but not said enlarged head thereof.
