DETAILED DESCRIPTION OF THE INVENTION
Referring initially to FIG. 1 of the drawing, depicted at 20 therein is a wall patch system constructed in accordance with, and embodying, the principles of the present invention. The wall patch system 20 is shown in the drawing covering a hole 22 formed in a section of drywall 24. The hole 22 may be purposely formed or may be formed by accident. In any event, the hole 22 should be repaired aesthetic and possibly functional reasons.
The drywall 24 is conventionally formed by drywall material that has io been mudded and taped at the seams, primed, and coated with finish coat of texture material and/or paint. The drywall 24 is conventional and will be described herein only to the extent necessary for a complete understanding of the present invention.
The wall patch system 20 comprises a plate member 30 and a is mesh sheet assembly 32. The plate member 30 can be made of any relatively rigid sheet material such as metal or plastic. Shown in FIG. 1 is an example plate member 30a made of a metal such as aluminum or steel and comprising a scored portion 34.
FIGS. 2-3 further illustrate that the plate member 30a may be 2o formed from a larger plate member 30 comprising a plurality of scored portions 34a and 34b in the form of straight lines. Part of the material forming the plate member 30 is stamped, cut, or otherwise worked at the scored portions to create a weakened portion of the plate member 30.
The example scored portions 34a and 34b divide the plate member into a 2s plurality of plate portions 36a, 36b, 36c, and 36d.
The larger plate member 30 may be used intact to cover a hole 22 of relatively large dimensions. In this case, the scored portions 34a and 34b are not used; these scored portions 34a and 34b do not affect the ability of the plate member 30 to function as the primary structural portion so of a wall patch.
_5_ However, the scored portions 34 allow the larger plate member 30 to be separated by hand along either of the scored portions 34a and 34b into a plurality of intermediate-sized plate members such as the plate members 30a and 30b shown in FIG. 4. In particular, the user simply grasps the plate member 30 on either side of the desired score portion, in this case the scored portion 34a, and bends the plate member one or more times along the scored portion 34a until the plate member 30 breaks into the smaller plate members 30a and 30b. The plate portions 30a and 30b comprise score portions 34c and 34d, respectively.
to As will be described in detail below, at least one of the intermediate plate members 30a and 30b may be sized and dimensioned to fit the dimensions of the hole 22 without excessive overlap beyond the edges of the hole 22. In this case, the plate members 30a and/or 30b may be used as shown in FIG. 4 to patch a hole 22 of appropriate dimensions.
is If, however, the plate members 30a and 30b excessively overlap beyond the edges of the hole 22, either of these smaller plate members 30a or 30b may be broken along the score portions 34c and 34d into even smaller plate members 30c and 30d as shown in FIG. 4A. As an example, FIG. 4A depicts the situation in which the intermediate-sized plate member 20 30a is broken along the scored portion 34c to obtain the plate members 30c and 30d. In the example wall patch system 20, the scored portion 34c is located such that plate portion 36a is larger than the plate portion 36c, resulting in the plate member 30c being bigger than the plate member 30d.
The formation of the original scored portions 34a and 34b on the 2s original plate member 30 thus provides the user with significant flexibility in providing a plate member 30, 30a, 30b, 30c, or 30d of appropriate size to efficiently cover holes 22 of a large range of sizes.
The process of covering the hole using a plate member 30 of an appropriate size will now be described with reference to FIGS. 1 and 5.
3o FIGS. 1 and 5 illustrate the mesh sheet assembly 32 comprises a mesh or surface sheet 40 and a release paper 42. The mesh sheet 40 comprises a mesh layer 50 and an adhesive layer 52. The mesh layer 50 is formed by a matrix of material defining openings or indentations that allow drywall mud or the like to grip the mesh layer 50 as will be described in further s detail below. Typically, the mesh layer 50 is formed by a non-woven grid of bonded glass fibers, but other materials and configurations can be used to form the mesh layer 50. For example, the mesh layer 50 can be formed of metal, polymers, or other materials configured to form the desired openings or indentations by perforations, weaving, or the like.
io The adhesive layer 52 may take the form of a solid layer of material to which the mesh layer 50 is attached. Alternatively, the adhesive layer 52 may be formed by spraying adhesive material in wet form onto the mesh layer 50 and allowing the adhesive material to dry in the form of an adhesive coating on one side of the mesh layer 50, in which case the is adhesive layer 52 will not be solid. In the example mesh sheet 40, the adhesive layer 52 is sprayed onto the grid of glass fibers forming the mesh layer 50. The adhesive layer 52 should be formulated to bond securely both to the mesh layer and to drywall material, whether the drywall material is bare or coated with a finish coat.
2o The release paper 42 is formed of a material having at least one surface designed to stick to the adhesive layer 52 during transportation and storage during transportation and storage but which allows the release paper 42 to be peeled away from the adhesive layer 52 immediately prior to use. The release paper 52 prevents the adhesive layer 52 from 2s inadvertently sticking to packaging materials and the plate member 30 prior to use. The release paper 52 also protects the adhesive layer 52 from contamination prior to use and during cutting of the mesh sheet 40 as will be described below.
Referring now again for a moment to FIG. 1, it can be seen that the 3o hole 22 defines a hole surface area 60, a first hole perimeter area 62, and a second hole perimeter area 64. The example hole surface area 60 is an irregular closed shape defined by the actual surface area of the wall 24 removed to form the hole 22. The example first hole perimeter area 62 is a rectangular shape that surrounds the hole surface area 60. The s example second hole perimeter area 64 is also a rectangular shape that surrounds the first hole perimeter area 62. As shown by broken lines in FIGS. 1 and 5, the plate member 30 is sized and dimensioned to match the first hole perimeter area 62, while the mesh sheet 40 is sized and dimensioned to match the second hole perimeter area.
io The process of using the wall patch system 20 will now be described in further detail. First, the dimensions of the first hole perimeter area 62 are determined based on the dimensions of the hole 22. The first hole perimeter area 62 should be slightly larger than the hole surface area 60 so that the plate member 30a has firm support around the entire hole is 22. The exact dimensions of the first hole perimeter area 62 relative to the hole surface area 60 but can very depending upon the particular circumstances. For example, a larger hole may require more overlap of the plate member 30a with the wall 24 around the hole 22. The dimensions of the first hole perimeter area 62 should also be determined 2o based on the sizes of the plate portions 36, both individually and added together.
Once the dimensions of the first hole perimeter area 62 are determined, the plate member 30 may be separated into at least one piece corresponding to the dimensions of the first hole perimeter area if the 2s original plate member 30 is too large. In the example system 20, the dimensions of the first hole perimeter area 62 substantially match the area of the combined plate portions 36a and 36c. Accordingly, the plate member is bent along the scored portion 34a as shown in FIG. 3 to form the smaller plate members 30a and 30b shown in FIG. 4. The plate 3o member 30a comprises the plate portions 36a and 36c and thus has _$_ substantially the same cross-sectional area as the first hole perimeter area 62.
Next, the dimensions of the second hole perimeter area 64 are determined. The dimensions of the second hole perimeter area 64 are s determined based on the size of the first hole perimeter area 62. In particular, the mesh sheet 40 is cut to a size slightly larger than that of the plate member 30a. Again, the exact dimensions of the mesh sheet 40 are not critical. However, enough overlap should exist between the mesh sheet 40 and the wall 24 beyond the plate member 30a that the adhesive io layer 52 securely holds the plate member 30a and the mesh layer 50 in place over the hole 22. A grid or design may be imprinted on the release paper 42 to facilitate the cutting of mesh sheet 40 to the appropriate size.
As mentioned above, the mesh sheet 40 should be cut as part of the mesh sheet assembly 32 (with the release paper 42 attached), but the mesh is sheet 42 may be cut with the release paper 42 removed.
After mesh sheet 40 is trimmed to the proper size as described above, the release paper 42 is removed (if not already removed). The plate member 30a is then brought into contact with the adhesive layer 52 such that the plate member 30a is attached to a central portion of the 2o mesh sheet as shown in FIG. 6 to form a patch assembly 70.
Then, as shown in F1G. 7, the patch assembly 70 is then brought into contact with the wall 24 such that the plate member 30a covers the hole 22, with a portion of the plate member 30a preferably overlapping with the wall 24 around the entire hole 22. In this configuration, the 2s adhesive layer 52 comes into contact with the wall 24 around the plate member 30a to hold the patch assembly 70 in place over the hole 22.
At this point, the hole 22 is patched. However, as shown in the close up of FIG. 8, drywall mud 80 is preferably placed over the patch assembly 70. While wet, the drywall mud 80 is feathered beyond the 3o edges of the mesh sheet 40 and worked into the indentations formed by _g_ the mesh sheet. When the drywall mud 80 dries, the drywall mud 80 mechanically engages the holes andlor indentations formed by the mesh sheet 40 to hold the dried drywall mud in place. The drywall mud 80 is then typically sanded.
As shown in FIG. 8, a finish layer 90 is then typically formed over the dried drywall mud 80. The finish layer 90 typically comprises a layer of primer and paint and may also comprise conventional texture material if necessary to match a texture of the wall 22 surrounding the patch assembly 70.

is If, however, the plate members 30a and 30b excessively overlap beyond the edges of the hole 22, either of these smaller plate members 30a or 30b may be broken along the score portions 34c and 34d into even smaller plate members 30c and 30d as shown in FIG. 4A. As an example, FIG. 4A depicts the situation in which the intermediate-sized plate member 20 30a is broken along the scored portion 34c to obtain the plate members 30c and 30d. In the example wall patch system 20, the scored portion 34c is located such that plate portion 36a is larger than the plate portion 36c, resulting in the plate member 30c being bigger than the plate member 30d.
The formation of the original scored portions 34a and 34b on the 2s original plate member 30 thus provides the user with significant flexibility in providing a plate member 30, 30a, 30b, 30c, or 30d of appropriate size to efficiently cover holes 22 of a large range of sizes.

While wet, the drywall mud 80 is feathered beyond the 3o edges of the mesh sheet 40 and worked into the indentations formed by _g_ the mesh sheet. When the drywall mud 80 dries, the drywall mud 80 mechanically engages the holes andlor indentations formed by the mesh sheet 40 to hold the dried drywall mud in place. The drywall mud 80 is then typically sanded.
As shown in FIG. 8, a finish layer 90 is then typically formed over the dried drywall mud 80. The finish layer 90 typically comprises a layer of primer and paint and may also comprise conventional texture material if necessary to match a texture of the wall 22 surrounding the patch assembly 70.
