FIELD OF THE INVENTION
This invention relates to a drywall apparatus and method, and more particularly to a system for creating a reveal between a baseboard and a drywall board, and method for doing same.
BACKGROUND OF THE INVENTION
One aesthetically pleasing way to construct a wall using gypsum or drywall board involves leaving a gap of approximately 1 cm between a baseboard and a drywall board above it. This gap is referred to as a “reveal.” A typical method for creating a drywall reveal is to use a “Z-shaped” moulding that is glued and/or stapled on the front side of the drywall at the bottom thereof. In position, the moulding gives a clean line along the bottom front edge of the board. The moulding is also designed to cover the back of the recessed space or gap between the drywall board and the baseboard to hide the studs or insulation behind the board.
The moulding is fastened to a standard drywall board at the job site. Drywall compound is then added to the moulding and drywall board, and then feathered out. After drying, the compound is sanded. This process of applying compound, feathering and sanding may be repeated several times with the aim of achieving a transition from the raised surface of the moulding to the surface of the drywall that is seamless and cannot be seen when the wall is painted. This process is relatively time consuming and costly.
It is an object of the present invention to provide a system and method for forming a drywall reveal that does not involve so many steps.
SUMMARY OF THE INVENTION
A drywall board system for use in conjunction with a baseboard is described. The drywall board system includes a drywall board for securing to framing members. The drywall board has a back side designed to be adjacent to the framing members when the drywall board is secured thereto, and a front side opposite the back side. Framing drywall liner lines the back side while finishing drywall liner lines the front side. Gypsum material is sandwiched between the framing and finishing drywall liners. The drywall board system further includes a board backing for receiving at least a portion of the baseboard. The board backing is fastened to the back side of the drywall board, such that the board backing extends downward from a bottom of the drywall board.
The board backing may be fastened to the back side of the drywall board with at least one of screws screwed into the back side, nails driven into the back side and adhesive applied to either the gypsum material at the back side or the framing drywall liner.
Also described herein is a baseboard system for use in conjunction with a drywall board. The baseboard system includes a baseboard for securing to framing members. The baseboard has a back side designed to be adjacent to the framing members when the baseboard is secured thereto, and a front side opposite the back side. The baseboard system also includes a board backing for receiving a portion of a drywall board. The board backing is fastened to the back side of the baseboard and extends upwards from the top of the baseboard.

DETAILED DESCRIPTION
FIGS. 1A and 1B show a front and cross sectional view, respectively, of a drywall board system 10 having a drywall board 11 for securing to framing members 12. As explained in more detail below, FIG. 1A does not include a baseboard 28, whereas FIG. 1B includes a baseboard 28. Framing members 12 can include wood or metal studs to which the drywall board 11 may be screwed or nailed. The drywall board 11 has a back side 14 and a front side 16 opposite the back side 14. The back side 14 is the side of the drywall board 11 that is adjacent to the framing members 12 when the drywall board 11 is screwed or nailed thereto. The front side 16, on the other hand, is the opposite side of the drywall board 11 that, after installation, is usually painted, plastered, wall papered or otherwise finished. The back side 14 has framing drywall liner 18, such as drywall paper. The front side 16 has finishing drywall liner 20, such as drywall paper. The framing drywall liner 18 and the finishing drywall liner 20 may be the same, or may have different characteristics, such as different thicknesses. Gypsum material 22 is sandwiched between the framing drywall liner 18 and the finishing drywall liner 20.
In addition to the drywall board 11, the drywall board system 10 further includes a board backing 24 that is fastened to the back side 14 of the drywall board 11. The board backing 24 extends downward from a bottom 26 of the drywall board 11, in one embodiment without contacting the front side 16 of the drywall board 11. The term “bottom” refers to a portion of the board 11 that, when the drywall board system 10 is installed, would be nearest the floor. The board backing 24 receives a portion of a baseboard 28 to form a reveal. The term “receive” can include embodiments in which the baseboard 28 abuts or overlaps the board backing 24. In one embodiment, the board backing 24 extends downward from the bottom 26 of the drywall board 11 by about two inches.
The board backing 24 may be attached to the back side 14 of the drywall board 11 with fasteners, such as screws 29 that are screwed through the framing drywall liner 18 and into the gypsum material 22 without piercing the finishing drywall liner 20. Alternatively, the board backing 24 may be fastened to the back side 14 of the drywall board 11 by bonding with adhesive, for example.
In one embodiment, the board backing 24 contains metal that is attracted to magnetic material in the baseboard 28, or the opposite arrangement where the baseboard 28 contains metal and the board backing 24 contains magnetic material is also possible. The attraction of the metal to the magnetic material helps affix the baseboard 28 to the board backing 24. The metal can be white, pre-coated steel or aluminum, for example. In one embodiment, the thickness of the board backing 24 is about 0.032 inches.
FIGS. 2A-C show an embodiment consistent with the present invention that employs a magnet. Pockets 30 are stamped into a metallic board backing 24. Complimentary magnetic projections 32 are disposed on the surface of the baseboard 28 projecting from the rear of the baseboard 28 (see FIG. 2C). The magnetic projections 32 fit into the pockets 30 and are affixed thereto, in whole or in part, via the attraction between magnetic material in the magnetic projections 32 and the metallic baseboard backing 24. The attraction of the metal to the magnetic material helps affix the baseboard 28 to the board backing 24 in an appropriate position. The appropriate position would leave the board backing 24 leveled and at the right height to leave a suitable gap for the reveal. The gap, for example, can be in the range of 1-3 cm. It is also contemplated that instead of having the pockets 30 in the board backing 24 and the projections 32 in the baseboard 28, the pockets can reside in the baseboard and the projections in the board backing.
It is aesthetically desirable for the front bottom edge of the drywall board 11 to have a sharp edge. At least two ways to form this edge are now described.
With reference to FIGS. 3A and 3B, a horizontal groove 50 is formed on the back side 14 of the drywall board 11. A hingeable lower lip 52 is thus created at the bottom of the drywall board 11. In FIG. 3B, the lip 52 is shown in a folded position attained by rotating the lip 52 to close the groove 50, which action is suggested by the dashed arrow in FIG. 3A. Adhesive, for example, can be used to keep the lip 52 in the folded position shown in FIG. 3B.
FIGS. 4A and 4B show a different horizontal groove 60 formed on the back side 14 of the drywall board 11. A hingeable lower lip 62 is thus created at the bottom of the drywall board 11. In FIG. 4B, the lip 62 is shown in a folded position attained by rotating the lip 62 to close the groove, which action is suggested by the dashed arrow in FIG. 4A. As in the previous embodiment, adhesive can be used to keep the lip 62 in the folded position shown in FIG. 4B.
Instead of disposing a backing on the drywall board, the backing can instead be disposed on the baseboard. Such an alternative is described in FIGS. 5A (front view) and 5B (cross-sectional view), where a baseboard system 100 that accepts a drywall board 128 is shown. As explained in more detail below, FIG. 5A does not include a drywall board, whereas FIG. 5B includes a drywall board 128. The drywall board 128 is secured to framing members 112. Framing members 112 can include wood or metal studs to which the baseboard system 100 may also be screwed or nailed. The baseboard system 100 includes a baseboard 107 having a back side 114 and a front side 116 opposite the back side 114. The back side 114 is the side of the baseboard 107 that is adjacent to the framing members 112 when the baseboard system 100 is affixed thereto, such as with screws or nails. The front side 116, on the other hand, is the opposite side of the baseboard 107 that, after installation, may be left as is, painted or otherwise finished. The baseboard 107 is comprised of an appropriate material, such as wood, gypsum material, elastomer, plastic, metal, stone, medium density fiberboard (MDF), or polyurethane.
In addition to the baseboard 107, the baseboard system 100 further includes a board backing 124. The board backing 124 extends upward from a top 126 of the baseboard 107, in one embodiment without contacting the front side 116 of the baseboard 10. The term “top” refers to a portion of the baseboard 107, which, when the baseboard system 100 is installed, would usually be the portion furthest from the floor. The board backing 124 receives a portion of a drywall board 128 to form a reveal or gap 130 between the baseboard 107 and the drywall board 128. The term “receives” can include embodiments in which the drywall board 128 abuts or overlaps the board backing 124. In the former case, when the drywall board 128 is meant to merely abut the board backing 124, the height of the portion of the board backing 124 that extends above the top 126 of the baseboard 107 would be the height of the reveal.
In some embodiments, the board backing 124 can be rigid or semi-rigid to allow some flex, and can be composed of wood, elastomer, plastic, polyurethane or metal.
In one embodiment, the baseboard 107 and the board backing 124 are two separate pieces that are fastened together, such as with nails, screws or adhesive. In another embodiment, the baseboard and board backing may be formed as one piece. For example, such a baseboard system may be manufactured by injection moulding or die casting using a single mould. For this purpose, the baseboard system may be made out of metal, elastomer or thermoplastic.
The height of the portion of the backing 124 that extends upwards past the top of the baseboard 107 can range from the height of the intended reveal to many centimeters beyond. In one embodiment, the height of this portion of the backing can be one centimeter or less. This would be useful in a process where the drywall board 128 is affixed to the studs 112 before the baseboard system. In such case, the relatively short height of the portion of the backing 124 can be squeezed between the drywall board 128 and the studs 112.
FIGS. 6A-C show another embodiment of a baseboard system having a flange. The baseboard system 150, which includes a baseboard 154, of FIG. 6 is similar to the baseboard system 100, but in addition has a board backing 152 that includes a flange 153 that runs longitudinally. The vertical distance 155 from the top of the baseboard 154 to the flange 153 corresponds to the height of the reveal or gap that is created. Advantageously, as shown in FIG. 6C, a drywall board 156 can rest on the flange 153 while the board is being secured to the studs 158. The depth 157 of the flange 153, which in FIGS. 6B and 6C is the distance of the flange as measured from left to right is no larger than the thickness of the drywall board, e.g., half the thickness. In a preferred embodiment, the flange 153 has a depth that is large enough to allow the drywall board 156 to rest thereon, but small enough that it is not easily seen after the baseboard system 150 and drywall board 156 are installed. In one embodiment, a range for the depth of the flange of 25% to 75% of the thickness of the drywall board is appropriate. If the thickness of the board is ½ of an inch, this corresponds to a range for the depth of the flange of 0.125-0.375 inches; if the thickness is ⅜ of an inch, this corresponds to a depth of 0.0938-0.281 inches. In another embodiment, the depth of the flange is equal to the thickness of the drywall board.
It will be appreciated that while the flange 153 in the embodiment of FIGS. 6A-6C is disposed approximately midway up the backing 152, in another embodiment the flange can be disposed at or near the top of the backing 152, including the very top. In the latter case, where the flange 153 is disposed at the very top of the backing, no amount of backing extends above the flange. Such a configuration might be employed when the drywall board 156 is affixed to the studs 158 first, before the baseboard system 150 is affixed to the studs.
In addition to providing a resting surface for the drywall board 156 that makes installation easier, the flange 153 furnishes the correct height and levelling of the reveal without having to make measurements.
FIG. 7 shows a flow chart for constructing a reveal using the baseboard system of FIGS. 6A-C. In step 200, at least one flooring spacer is disposed on a subfloor. The flooring spacer can be a block of wood or any other appropriate material that has the same height as the flooring that will be installed on the subfloor. Alternatively, the flooring spacer can be an element of the flooring that will be installed on the subflooring, such as a hardwood, cork, bamboo floorboard, or tile. In step 202, the baseboard system is placed on the at least one flooring spacer. In step 204, the baseboard system is fastened to framing members, such as wood studs, with screws or nails. In step 206, a drywall board is placed on the flange to rest thereon. In step 208, the drywall board is fastened to the board backing and to the studs. In optional step 210, the at least one flooring spacer can be removed. The flooring spacer would typically be removed if the flooring spacer is a block of wood used merely for spacing. On the other hand, if the flooring spacer is a floorboard, the flooring spacer can be left in place if the floorboard is one of many other floorboards comprising the flooring, and more floorboards are to be added on the subflooring to complete the flooring. In the latter case, the floorboard can optionally be removed until the drywall is installed, at which point the flooring can be installed. Such might be the case if the drywall boards or baseboard is to be painted; by removing the floorboards, one avoids getting paint splatter on the floorboards. In any of these alternatives, a suitable spacing is achieved between the bottom of the baseboard and the subflooring to ensure proper fitting of the flooring members therebetween.
In this vain, some or all of the baseboard can be covered or shrink wrapped with a protective plastic, or other suitable material, to avoid getting paint splatter on the baseboard if the drywall above the baseboard is to be painted. After the paint dries, the cover or shrink wrap on the baseboard is designed to be easily removed.
