 Smithtown, N.Y. 11788; Albert Mauceri, 69 Bretton Rd., Hauppage, NY. 11787 [22] Filed: Aug. 2, 1973 [21] Appl. No.: 384,872  
 Primary ExaminerWilliam 1. Price Assistant Examiner-Douglas B. Farrow Attorney, Agent, or Firm-Allison C. Collard [57] 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&#39;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 and to 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 al lowing 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.  
 3 Claims, 5 Drawing Figures I WALL CREVICE REPAIR KIT v This invention relates to a wall pat&#39;ch kit and more particularly. to a wall pa-tch kit having preformed patch. 5  
  It has been found to be difficultto repair apertures or crevices created when sheet/rock walls crack and open. It has been suggested to place paper in the crevice and then apply. a plaster material over the paper to restore the wall surface. However. if the crevice is large, it is difficult to obtain a patch having a strong and flat surface.  
  Accordingly, the present invention overcomes the aforementioned difficulties by providing in the preferred embodiment. a preformed patch secured to one side of a rigid. backboard. The backboard is slightly larger than the patch. The backboard is supplied with a longitudinal score line and the patch is cut in half. with the sections abutting. The abutting sections result in an included plane that is disposed parallel with and aligned on the score line. This permits the backboard and accompanying patch to fold. The folded structure is then inserted through a cut made about where the crevice existed. To effect accurate registration of the cut, the inventive device provides a templet substantially complimentary with the patch periphery.  
  Adhesive means coats an exposed portion or border disposed about the preformed patch. The inventive device provides for pull means or strings engaging the backboard to permit the patch to be drawn flush with the wall face. Accordingly, the adhesive means in conjunction with the strings allow the patch to be securely positioned in the wall as the adhesively coated border engages the wall surface interior.  
  It is, therefore, an object of the present invention to provide a wall patch that minimizes the repair area and eliminates the need for excessive amounts of spackle or plaster.  
  It is another object of the present invention to provide a sheet rock patch kit that is simple in design, and easy to manufacture.  
  Other objects and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawings. It is to be understood, however, that the drawings are designed for the purposes of illustration only and not as a definition of the limits of the invention.  
  In the drawings, wherein similar numerals denote similar elements throughout the several views:  
 FIG. I is a perspective view of the inventive patch kit;  
  FIG. 2 is a perspective view of the two kinds of templets according to the inventive device, either of which may be used for positioning about the wall crevice:  
  FIG. 3 is a plan view of the wall crevice showing the templet outline in position;  
  FIG. 4 shows the wall cutout and insertion of the inventive device: and  
  FIG. 5 shows the inventive patch kit secured in the wall crevice and ready for application of plaster or spackle material.  
  Referring now to the drawings, and in particular. FIG. I. there is shown the inventive patch kit seen generally as II) having a rigid backboard I2. Backboard 12 carries both a sheet rock patch I4 and a score line 16. Score line I6 extends preferably along the longitudinal central axis of backboard I2. Patch I4 is cut approximately in half and is affixed to backboard 12 so that sheet ro&#39;ck half sections abut in a plane 14a that intersects with andis parallel to score line 16. Patch 14. while having substantially the same configuration or area of backboard 12, is dimensionally smaller, providing for a border area existing between the patch extremity and the backboard edge.  
  Adhesive means 18 is carried on the border area allowing the rigid backboard to fasten securely to the interior of the wall surface.  
  At least one pull means 20 which in the preferred embodiment comprises strings, is disposed through backboard 12 and around the back of patch 14. String 20 is provided with a predetermined amount of slack.  
  It will be apparent that the resulting structure may then be folded along score line 16 in the direction of arrows F as seen in FIG. I.  
  Adhesive means I8 will preferably comprise a pressure sensitive adhesive. However, it is to be understood that adhesive means 18 may comprise any suitable glue-type material as common in the art.  
  The inventive device also contemplates supplying a rigid board. In another embodiment, backboard I2 is devoid of score line 16. Accordingly, patch 14 may comprise a solid slab affixed to the unscribed board. The unscribed backboard may then be inserted lengthwise in a wall cut, described hereinafter.  
  Referring now to FIG. 2. there is shown two templets 22 and 22a, one of which, templet 22. is cut so as to have its outer periphery 22(- substantially complimentary with the outer periphery of sheet rock patch 14. Templet 22 in the preferred embodiment will be a translucent material so that it may be placed over the wall crevice and thereby allow its visual orientation in relation to the wall&#39;crack.  
  Templet 220 contains an included cut-out 22h. Cutout 22b has its periphery substantially complimentary with the outer periphery of patch I4.  
  In operation, either templet 22 or templet 22a is positioned over the wall crevice. It is then possible to scribe or mark an outline 22d of either templet on the wall surface as seen in FIG. 3. Scribe marks 22d will then define the outer periphery of a patch size cut that is to be made about the wall crevice.  
  Referring now to FIG. 4, there is shown the resulting aperture that is produced by cutting along the scribe marks 22d of FIG. 3.  
  Rigid backboard I2 is then folded along score line I6 in direction F as above described. Either before or after the folding or bending of rigid backboard l2, adhesive surface 18 is prepared which in the preferred embodiment will comprise peeling a protective release paper from the adhesive film.  
 It is then possible to insert the inventive device in the patch size wall cut as indicated in FIG. 4 wherein the patch faces the wall aperture or cut. Upon insertion of the rigid backboard through the wall aperture it is then possible to grasp strings or pull devices 20 and cause the sheet rock patch to engage the periphery of the squarely cut wall aperture. Adhesive means 18 will secure backboard 12 to the interior wall surfaces adjacent the cut.  
  As seen in FIG. 5, the resulting sheet rock patch substantially fills the aperture or cut and it is then merely necessary to remove or cut the pull devices 20 that remain along the patched wall surface.  
  It will be appreciated that patch material 14 effectively fills the entire void. The area is then coated with plaster or spackle so that the interstieies existing between the patch material and the wall cut, and the longitudinal break in the patch material itself are filled. After the plaster has dried the wall surface may be prepared to match the surrounding area.  
  While only a few embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that many changes and modifications may be made thereto without departing from the spirit and scope of the invention.  
  What is claimed is: l. 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 eircumseribed 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. 2. The kit as in claim I wherein said backboard ineludes 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.  
 3. The wallboard kit as recited in claim I wherein said template is translucent.
