Description
Background of the Invention
The present invention generally concerns the plaster and drywall art and more particularly pertains to an improved laminate patch for repairing a hole in an interior wall surface from the facing surface thereof.
There has long been a need in the art for inexpensive wall repair systems, which are relatively uncomplicated and which may be utilized by the non-professional, such as the homeowner. Prior art devices have generally been disposable in the interior of the wall and have functioned to serve as backing plates for plaster or other wall repair materials. The prior art devices have been adequate in their functioning for that purpose. However, many such devices have been unduly complicated in structure, and hence expensive to produce and complicated to use.
Accordingly, in view of the shortcomings of the prior art, it is an object of the improved laminate patch of the present invention to provide an inexpensive, relatively uncomplicated, and fireproof patch for applying on the surface of an interior wall having a hole therein to be repaired.
It is an additional object of the improved laminate patch of the present invention to provide a patch which is applied directly on the facing surface of the interior wall, and hence requires no support from the opposite wall.
It is a further object of the improved laminate patch of the present invention to provide a patch which will provide a smooth transition between the wall surface and that of the wall repair compound applied over the laminate patch to complete the repair.
It is a yet further object of the improved laminate patch of the present invention to provide a patch which may be easily cut by scissors or other means for fitting around a miscut switch plate or light fixture hole, or a pipe projecting from the wall surface to seal the wall, especially from the elements and/or insects.
These and other objects and advantages of the improved laminate patch of the present invention will become apparent to one skilled in the art upon review of the following description and drawing.
Summary of the Invention
The improved laminate patch of the present invention is particularly suitable for closing an opening on the facing surface of an interior wall by means of a thin plate of non-combustible material. For purposes of the present invention, the term "wall surface" includes the facing surfaces of both vertical walls and ceilings, and whether made of drywall, plaster or other wall material. The thin plate has on one side thereof a central portion for covering the opening to be closed in the wall surface. A periphery surrounds the central portion on the thin plate, and when disposed into intimate proximity with the wall surface is held thereagainst by means of an adhesive.
A plate cover means is laminated at the interior surface thereof to the outer side of the thin plate for covering it and for extending over and smoothly covering the edge portions thereof. The repair is then completed by applying plaster, spackle or other wall repair compound over the exterior surface of the laminate patch to effect a smooth and substantially planar surface.
The thin plate is made of a non-combustible material, preferably thin gauge aluminum sheeting, which may easily be cut by scissors. The adhesive coating for bonding the thin plate to the wall surface is preferably a two-sided adhesive tape, although pressure sensitive adhesive compounds may be applied directly to the thin plate. The plate cover material preferably comprises a fibrous material with an exterior surface of porosity sufficient to be bonded to a wall finishing compound to complete the repair. Paper or fabric are examples of such a material.
The plate cover includes an outer margin which extends over the edge portions of the thin plate preferably for a substantial distance and bears an adhesive on the inner surface thereof for bonding the plate cover directly to the wall surface to provide a substantially planar configuration with respect to the wall surface for receiving a thin coating of plaster to effect a smooth and invisible repair.

Detailed Description of the Preferred Embodiments
Referring now to the drawing and FIG. 1 in particular, the improved laminate patch of the present invention, shown generally at 10, is formed from a thin and relatively rigid plate 12 which is made of a non-combustible material, preferably thin gauge aluminum sheeting. Aluminum sheeting is most suitable because of its relatively light weight and because aluminum may be easily trimmed to size or may have a hole cut therein to accommodate and seal a pipe extending from the wall surface. Aluminum sheeting also is easily bent to repair a hole at a wall corner.
Plate 12 is covered at least in part by an adhesive coating 14 for firmly bonding plate 12 at its interior side 13 into intimate proximity to the wall surface 11 to be repaired. A plate cover 16 is laminated on the interior surface 17 thereof to the exterior side of plate 12 to cover the plate 12 and to form a smooth transition from plate 12 over the edges 15 thereof and onto wall surface 11. Plate cover 16 has a preferably presssure sensitive adhesive layer 18 applied to the interior surface 17 thereof to bond plate cover 16 to wall surface 11. A release coated film 20 may be applied to the improved laminate patch 10, which film 20 is to be stripped away prior to use.
Referring now to FIG. 2, improved laminate patch 10 is shown disposed on a section of drywall generally designated at 22, and comprising paper layers 24, 26 sandwiching a plaster layer 29. Plate 12 and plate cover 16 are shown in phantom covering the hole or opening 30 to be repaired.
Referring now to FIG. 3, improved laminate patch 10 is shown applied to repair hole 30 in drywall 22, and when installed is covered by a thin layer of plaster, spackle or other wall repair compound 32. Plate 12 has a central portion 33 on interior side 13 thereof for covering opening 30 in drywall section 22, and a periphery 34 on interior side 13 thereof for disposition into intimate proximity with drywall surface 11 and is bordered by edges 15. Adhesive coating 14 is disposed on interior side 13 of plate 12 over at least a substantial portion of the periphery thereof and alternatively over the entire interior surface 13 of plate 12 for firmly bonding plate 12 to drywall surface 11 to be repaired. The plate cover 16 is laminated at the interior surface 17 thereof to the exterior side of plate 12 for covering plate 12 and for extending over the edges 15 of plate 12 to form the smooth transition between plate 12 and wall surface 11.
The improved laminate patch 10 of the present invention is used by removing the stripable, release coated backing 20 and applying patch 10 with pressure over the hole or opening 30 in wall surface 11. After plate 12 and plate cover 16 have been pressed firmly against wall surface 11, plaster, spackle or other wall repair compound is applied over patch 10 to complete the repair. The result is a smooth and planar wall surface. The improved laminate patch of the present invention is safe and easy to use and relatively inexpensive to manufacturer.
The improved laminate patch 10 of the present invention may be used to repair a variety of different types of holes in a wall surface, including for example, the hole around a pipe disposed through and projecting from the wall surface, a hole caused by wall damage, a miscut switch plate hole or light fixture hole. Improved laminate patch 10 may also be used in the same manner to repair a hole in a hollow door structure commonly manufactured of Masonite material.
Although the improved laminate patch of the present invention may be generally of any size or shape, generally a dimension of eight inches by eight inches will be large enough to cover any usually encountered holes. The aluminum sheeting used may be of any suitable gauge which is sufficiently rigid to serve as a backing for the wall finishing compound, such as plaster or spackle, but which is sufficiently light in gauge to have a thinness which does not protrude excessively from the wall surface. The paper and adhesives used may be of various types, although one paper which has been particularly successful for the plate cover has been "Fasson" made by Avery International, which is a paper coated with a pressure sensitive adhesive. The adhesive for coating the plate may be double-faced carpet tape in one preferred embodiment.
The basic and novel characteristics of the improved laminate patch of the present invention and the advantages thereof will be readily understood from the foregoing disclosure by those skilled in the art. It will become readily apparent that various changes and modifications may be made in the form, construction and arrangement of the elements thereof as set forth hereinabove without departing from the spirit and scope of the invention. Accordingly, the preferred and alternative embodiments of the present invention set forth hereinabove are not intended to limit such spirit and scope in any way.
