Abstract

Abstract A wall crevice repair kit includes a rigid backboard and a preformed sheet rock patch affixed to one face thereof. The preformed patch has a smaller area than the backboard allowing a border to form around the patch. A pressure-sensitive adhesive is carried on the border. The preformed patch is cut in half and the halves abut one against the other so as to define an included plane. A score line is provided along the central longitudinal axis of the backboard. The preformed patch is positioned on the board so as to have the included plane run parallel to and intersect with the score line. This permits the board and patch to fold in a predetermined direction. A templet is provided having substantially the same periphery as the patch allowing a mark to be made about the crevice and used to direct a patch-size cut in the wall. Additionally, the kit includes pull strings that run through the backboard and around the patch to facilitate insertion of the patch in the wall cut.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 154 words
A wallboard kit for repairing an opening in a wallboard surface comprising: a template having an area larger than the opening to be repaired; a preformed sheet rock patch identical in size to said template; a rigid backboard secured to said patch, said backboard being larger than said patch so as to define a border between the periphery of the patch and the edges of the backboard; an adhesive for disposal on the border of said backboard; at least one string connected to said patch; and plaster material for sealing the patch to the wallboard, so that after the wallboard opening is circumscribed by said template and cut out, said patch and backboard are inserted through the opening and pulled into place by said at least one string to permit the adhesive on the border to engage the wallboard, and thereby permit the plaster to seal the patch to the surface of the wallboard.
Claim 2
Dependent Claim 154 words
A wallboard kit for repairing an opening in a wallboard surface comprising: a template having an area larger than the opening to be repaired; a preformed sheet rock patch identical in size to said template; a rigid backboard secured to said patch, said backboard being larger than said patch so as to define a border between the periphery of the patch and the edges of the backboard; an adhesive for disposal on the border of said backboard; at least one string connected to said patch; and plaster material for sealing the patch to the wallboard, so that after the wallboard opening is circumscribed by said template and cut out, said patch and backboard are inserted through the opening and pulled into place by said at least one string to permit the adhesive on the border to engage the wallboard, and thereby permit the plaster to seal the patch to the surface of the wallboard.
Claim 3
Dependent Claim 70 words
The kit as in claim 1 wherein said backboard includes a longitudinal score line positioned so as to run substantially along the central longitudinal axis thereof and wherein said patch includes two halves abutted one against the other so as to define an included plane, the plane running parallel to and intersecting with the score line on said backboard permitting said backboard and patch to fold about the score line.
Claim 4
Dependent Claim 13 words
