Abstract
Description
- This application claims the benefit of priority to U.S. provisional patent application No. 62/844,568, filed May 7, 2019, the contents of which are herein incorporated by reference.
- Embodiments of the invention relates generally to methods and systems for repairing a wall. More particularly, the invention relates to a balloon that an be inflated inside a wall to provide a support for applying plaster, joint compound, spackle or other wall repair spreads in a hole in a wall.
- The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.
- Holes can be formed in a wall through various manners and can be presented in various sizes. Conventional wall repair kits include a patch or tape that one applies across the hole. Then, a compound is applied over the patch or tape, sanded and painted.
- It such repair kits, one must apply enough compound to cover the patch or tape, so that it does not show, yet cannot apply too much compound as to provide a bulge in the wall. Further, with such patches or tapes, it is difficult to make the repair have any substantial thickness, so that the wall repair area becomes a region susceptible to further damage. These conventional methods do not permit the compound placed over the hole to be even close to the thickness of the original wall.
- In view of the foregoing, there is a need for systems and methods for repairing walls that can overcome the deficiencies of conventional methods.
- Embodiments of the present invention provide a wall repair system comprising a backer board configured to be inserted into a hole in a wall, the wall having an outer side facing a living space and a back side facing an opposite wall back side of an opposite wall, the wall and the opposite wall forming a wall space therebetween; and a pressure generating means for pressing at least a portion of the backer board against the back side of the wall about at least a portion of a periphery of the hole.
- Embodiments of the present invention further provide a method for repairing a hole in a wall comprising inserting a deflated balloon into the hole in the wall; inflating the balloon; positioning the inflated balloon to press against at least a portion of an outer periphery of the hole on a back side of the wall; and building up repair material in the hole, against the inflated balloon.
- Embodiments of the present invention further provide a method for repairing a hole in a wall comprising inserting a backer board into the hole in the wall, the backer board having at least one threaded opening therethrough; threading at least one screw into the at least one threaded opening; positioning the backer board in a desired position to press against at least a portion of an outer periphery of the hole on a back side of the wall; turning the screw to cause a distal end thereof to press against a wall opposite the wall with the hole, thus securing the backboard in the desired position; and building up repair material in the hole, against the backer board.
- These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.

- Broadly, embodiments of the present invention provide a wall repair system that includes a balloon that can be inflated within a wall space behind a hole in the wall. The balloon, or, as described below, a backer board attached to the balloon, can provide a surface for placement or build up of wall repair compound so that the repaired wall has substantially the same thickness of the original wall and so that no tape or patch needs to be placed on top of the wall along any location surrounding the hole. In some embodiments, the backer board can have one or more threaded holes therethrough where a threaded rod can be inserted into the threaded holes to contact a wall surface opposite the hole, causing the backer board to stay in place against the back side of the wall having the hole therein, thus blocking all or a part of the hole.
- Referring to
FIGS. 1 through 3 , aballoon 10 can include afill port 12 having astraw 14 extending therefrom. Theballoon 10 may be designed so that thestraw 14 may be used to fill theballoon 10. When thestraw 14 is removed from theballoon 10, theballoon 10 may remain inflated. In other words, the air fillport 12 of the balloon may be self-sealing upon removal of thestraw 14. Theair fill port 12 can include various mechanisms for providing a self-sealingballoon 10 as may be known in the art. For example, a deformable plastic piece may fit around the fill port of theballoon 10, where insertion of thestraw 14 may cause the fill port to open around the straw, permitting inflation of theballoon 10. When thestraw 14 is removed, the resilient material may close the fill port to prevent deflation. Thestraw 14 may be any elongated tubular member and may be flexible, rigid, straight, bent, or combinations thereof. - In some embodiments, the
balloon 10 may be self-filling and be sealed with certain chemicals that create a gaseous product reaction to permit inflation of the balloon upon contact of the chemicals. For example, the balloon may include a first chamber having baking soda and a second chamber with citric acid, vinegar, or the like, so that, when the chambers are combined, the balloon self-inflates. - The system may include a
backer board 16 attached to a portion of the exterior of theballoon 10. Thebacker board 16 may be size adjustable by various means, such as scoring or marking of cut lines, so that thebacker board 16 may be sized to be, at least on one dimension, smaller than thehole 32 in thewall 30, permitting thebacker board 16 to be inserted with the deflatedballoon 10 into thehole 32 as shown inFIG. 4 . When theballoon 10 is inflated inside thewall space 18, thebacker board 16 can be aligned to provide a more firm backing for building up the wall repair. Thebacker board 16 may be made from various materials, such as cardboard, paperboard, plastic, wood, metal, or the like. Typically, thebacker board 16 may be relatively rigid, at least more rigid than theballoon 10, for example. In some embodiments, rather than being attached to theballoon 10, thebacker board 16 may be a separate piece that may be inserted during or after balloon inflation. - The
backer board 16 may be solid or may include a plurality of holes therethough for permitting the repair compound to engage there with. Thebacker board 16 may include a plurality ofscores 18 to permit easy size adjustment. In some embodiments, as shown inFIG. 6 , the scores may be arranged in concentric circles. - Referring back to
FIGS. 1, 4 and 5 , in use, theballoon 10 may be inflated within thewall space 34 so that either anouter edge 20 of theballoon 10, or abacker board 16, can be aligned with a back side (interior to the wall)portion 22 of thewall 30 at the location of thehole 32. Thus, theinflated balloon 10, or thebacker board 16, provides a backing to receive repair compound thereagainst. If conventional repair compound, such as joint compound or spackle, is used on a hole in the wall, as the hole fills with the repair compound, much of the compound can push out beyond the back surface of the wall and simply fall within the wall space. With the repair system of the present invention, a stop is provided to retain repair compound and this stop is positioned at or near a back surface of the wall. In this manner, when the repair is complete, the repaired section will have substantially the same thickness of the rest of the original wall and the repaired area may be smoothed or sanded to be flush with the surrounding wall, since there is no material added about the perimeter of the hole on the wall. - The wall repair system may be used to repair virtually any sized hole in a wall, provided that it is large enough to permit insertion of the balloon therein. Typically, the wall repair system may be used to repair holes from about 1 inch to about 8 inches, for example.
- In the above embodiment, the inflated balloon provides pressure for itself or a backer board to receive the build-up of the wall repair compound. Referring to
FIGS. 7 and 8 , in some embodiments, a threadedbacker board 70 can include one or more female threaded throughopenings 72. Ascrew 74 may be inserted into the through openings. Thescrew 74 may be long enough to permit the screw to contact anopposite wall 76 within thewall space 34, thus pushing the threadedbacker board 70 against theback side portion 22 of thewall 30 with thehole 32. An oppositewall contacting side 78 of thescrew 74 may have anenlarged head 80 to provide a large surface area to push against theopposite wall 76 during use. Theenlarged head 80 may be integral with thescrew 74 or may be attached to thescrew 74 during use and after threading thescrew 74 into the threadedopening 72. - The
hole facing side 82 of thescrew 74 can include ascrew engaging shape 84, such as Phillips-head shape, to permit a screwdriver to turn thescrew 74. The length of thescrew 74 may be pre-sized to fit within standard wall openings. For example, thescrew 74 may be from about 3.25 to about 3.75 inches in length for a standard 2×4 wall construction. Other screw lengths may be provided for other wall widths. - The threaded
backer board 70 may include hinges 86, or similar structure, to permit folding of the threadedbacker board 70. Typically, thehinges 86 may permit folding one or more sides of the threadedbacker board 70 outward (toward the hole when the threadedbacker board 70 is inserted into place behind the hole in the wall), but not inward (toward theopposite wall 76 in the wall space 34) so that, as thescrew 74 is tightened, causing the threadedbacker board 70 to push against at least a portion of the inner perimeter of the hole, the one or more hinged sides do not bent inward. - The threaded
backer board 70 may be scored to permit size adjustment and may include one or more hinged features to permit folding of the board for insertion and allowing for opening of the hinged features within the wall space. In use, thescrew 74 may provide a handle to hold the threadedbacker board 70 in the proper orientation for placement thereof. - In some embodiments, the threaded
backer board 70 may include a pressure sensitive adhesive with a removable backing strip. The threadedbacker board 70 may be inserted into thewall space 34, the removable backing strip may be removed, and at least a portion of the threadedbacker board 70 may adhere to the back side of the wall about at least a portion of the periphery of the hole. Such adhesive may hole the threadedbacker board 70 in place while the user tightens the one or more screws to more securely hold the threadedbacker board 70 in place. - All the features disclosed in this specification, including any accompanying abstract and drawings, may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.
- Claim elements and steps herein may have been numbered and/or lettered solely as an aid in readability and understanding. Any such numbering and lettering in itself is not intended to and should not be taken to indicate the ordering of elements and/or steps in the claims.
- Many alterations and modifications may be made by those having ordinary skill in the art without departing from the spirit and scope of the invention. Therefore, it must be understood that the illustrated embodiments have been set forth only for the purposes of examples and that they should not be taken as limiting the invention as defined by the following claims. For example, notwithstanding the fact that the elements of a claim are set forth below in a certain combination, it must be expressly understood that the invention includes other combinations of fewer, more or different ones of the disclosed elements.
- The words used in this specification to describe the invention and its various embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification the generic structure, material or acts of which they represent a single species.
- The definitions of the words or elements of the following claims are, therefore, defined in this specification to not only include the combination of elements which are literally set forth. In this sense it is therefore contemplated that an equivalent substitution of two or more elements may be made for any one of the elements in the claims below or that a single element may be substituted for two or more elements in a claim. Although elements may be described above as acting in certain combinations and even initially claimed as such, it is to be expressly understood that one or more elements from a claimed combination can in some cases be excised from the combination and that the claimed combination may be directed to a subcombination or variation of a subcombination.
- Insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalently within the scope of the claims. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements.
- The claims are thus to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted and also what incorporates the essential idea of the invention.
