Description
RELATED APPLICATION
[0001] Provisional Patent Application Serial No. 60/172,614, filed
Dec. 20, 1999, is claimed for priority purposes. A copy of this
provisional patent application is attached as Exhibit A, which is
incorporated by this reference in its entirety.
TECHNICAL FIELD
[0002] This invention relates to drywall installation, and, more
particularly, to drywall installation tools and methods.
BACKGROUND OF THE INVENTION
[0003] Drywall (also commonly referred to as or wallboard or
sheetrock) is commonly installed on studs to form the basis for
finished interior walls of residential and commercial buildings.
While drywall can come in many sizes, the typical sizes for
installation are in sheets four feet wide and eight or twelve feet
in length. These standard pieces or sheets of drywall are heavy and
difficult to install by one person alone. Accordingly, commonly at
least two people work to hold and install the sheets of drywall. In
construction, time is of the essence as it relates to
profitability. Use of multiple people reduces efficiency and,
therefore, adds to the cost of construction.
[0004] A particular problem associated with drywall or wallboard
installation relates to hanging the drywall on upper portions of a
stud wall. It is particularly difficult to hold drywall at elevated
positions on the stud wall for installation. It is also difficult
to hold the drywall so that it remains properly aligned with the
stud wall, the ceiling, etc. before being secured in place.
[0005] Another problem associated with drywall installation relates
to securing drywall just above the floor level. It is difficult to
reach down and hold the sheetrock in place. Again, commonly two
people are required to install drywall on lower areas of a stud
wall.
[0006] There is a need, therefore, for a drywall installation
apparatus and method that will allow a single person to hold and
install drywall on a stud wall, particularly at upper reaches and
lower areas of the stud wall. There is further a need to provide a
drywall installation apparatus that will keep the drywall properly
aligned with the studs forming the stud wall by a single person,
who installs the drywall secures the drywall to the stud wall by
fasteners, nails, or the like.
SUMMARY AND OBJECTS OF THE INVENTION
[0007] It is a primary object of the present invention to provide a
drywall installation apparatus and method that will allow
installation of a sheet of drywall on a stud wall by a single
person.
[0008] Another object of the present invention is to provide a
drywall installation apparatus and method that will maintain the
drywall in proper alignment relative to the stud wall while the
drywall is installed on the stud wall.
[0009] Another object of the invention is to provide a drywall
installation apparatus that can be adjusted to accommodate various
different heights for installing the drywall at different heights
on a stud wall.
[0010] Yet another object of the invention is to provide a drywall
installation apparatus that utilizes one of the vertical studs in a
stud wall as a guide to orient the drywall being installed on the
stud wall.
[0011] Another object of the present invention is to provide a
drywall installation apparatus that can be utilized both to install
drywall on lower areas of a stud wall just above a floor and upper
reaches of the stud wall.
[0012] Yet another object of the present invention is to provide a
drywall installation apparatus that supports the drywall with a
cradle during installation of the drywall.
[0013] The present invention relates to a drywall installation
apparatus and method, which comprises an extension, a support
coupled to the extension to receive and support a piece of drywall
during installation, and a base coupled to the extension. The base
includes an aperture for receiving a lifting device, such as the
lifting end of a roll jack. The extension is adjustable to install
drywall on a stud wall at various heights. In an alternative
embodiment, a kickstand may be utilized in connection with a lower
support mechanism to allow a piece of drywall to be installed on a
lower area of a stud wall and lifted in the desired vertical
position relative to the stud wall.
[0014] Other objects, features, and advantages of the invention
will become apparent from the following detailed description of the
invention with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0023] As shown in FIGS. 1-3, the present invention relates to a
drywall installation apparatus 10 which includes generally an
extension or extension section 12, a support or support section 14,
and a base or base section 16. With reference to FIGS. 1 and 2, the
extension section 12 more specifically comprises a tubular outer
member or tubular sleeve 18 (formed preferably of square tube
material), which telescopes over a lower rod 20 and an upper rod
22. Lower rod 20 includes a plurality of apertures 24, and upper
rod 22 includes a plurality of apertures 26 for receiving pin
assemblies 28, 30, respectively, to adjust the height of the
drywall installation apparatus. Pin assembly 30 is extended through
aperture 32 in the upper end oftubular sleeve 18 and through one of
the apertures 26 in the upper rod 22. Pin assembly 28 is similarly
inserted through aperture 34 in the tubular sleeve 18 and through
one of the plurality of apertures 24 in lower rod 20. The extension
12 allows the drywall installation apparatus 10 to be adjusted over
a wide range of heights. In a preferred embodiment, the drywall
installation apparatus 10 can be adjusted from a minimum height of
approximately two feet to a maximum height of approximately seven
feet.
[0024] Upper rod 22 and lower rod 20 both have generally square
cross-sections. In other words, both are tubular in configuration
and generally rectangular in cross-section. Upper rod 22 has a
slightly larger inside diameter as compared to the outside diameter
of lower rod 20. As such, the upper rod 22 may be inserted over
lower rod 20 and the two parts connected directly together, without
tubular sleeve 18, to form a relatively shorter drywall
installation apparatus 10. To accommodate the relatively smaller
cross-sectionally dimensioned lower rod 20, an insert 25 (FIG. 2)
is inserted into tubular sleeve 18 (as shown in phantom in FIG. 2)
and secured in place by welding or some other suitable securement
method. The insert 25 has essentially the same cross-sectional
dimensions as the upper rod 22 to allow the lower rod 20 to slide
inside of the tubular sleeve section 18 and held securely in place.
The insert 25 includes an aperture 27 which is aligned with
aperture 34 in tubular sleeve section 18 so that the pin assembly
28 can be secured through both the tubular sleeve section 18 and
insert member 25.
[0025] The support section 14, as shown in FIG. 3, comprises a
support plate 36, which may be in the form of a trough or cradle
(as shown in the embodiment of FIGS. 1-3). Those skilled in the art
will understand that the support 36 could be formed in any suitable
configuration that would support the weight of a sheet of drywall
and allow for installation. The support 36 is generally U-shaped,
with a back wall 38, a bottom wall 40, and a front wall 42.
Preferably, there is a gap 45 in front wall 42. This gap 45 is
formed by edges 43 formed in front wall 42. The gap 45 allows the
sheet of drywall (not shown) to rest firmly in position on the top
surfaces of the studs forming a stud wall. Even when the
installation apparatus 10 is raised or lowered, gap 45 allows
constant, flush contact of the piece of drywall with the studs.
Gussets 44 are welded between trough 36 and upper rod 22 for
increased strength and stability of the drywall installation
apparatus 10.
[0026] With continued reference to FIGS. 2 and 3, an alignment
member 46, more specifically shown in the preferred embodiment as a
stud guide 46, is secured, by welding or other suitable fastening
methods, to the upper rod 22 of the drywall installation apparatus
10. The stud guide 46 comprises opposed flanges 48, 50, which are
sized and spaced to be inserted over a stud forming a portion of a
stud wall on which the sheet of drywall is to be installed. The
opposed flanges 48, 50 are integrally connected by an integral,
interconnecting wall 52, which is welded to the upper rod 22. The
alignment member or stud guide 46 maintains the drywall
installation apparatus in the desired position when the sheet of
drywall is being raised and lowered relative to the stud wall. The
stud guide 46 prevents the combined drywall and drywall
installation apparatus 10 from tipping to one side or another
during the installation process.
[0027] The base section 16 more specifically comprises a foot piece
54. The foot piece includes an aperture where a lifting device can
be coupled so the leveraging force can be applied to lift the
drywall installation apparatus in combination with the sheet of
drywall for installation on a stud wall. The foot piece 54 of the
base 16 comprises opposed downward extension pieces 56, 58, which
extend downwardly from an integral cross member 60 which is welded,
in turn, to lower rod 20. The combined downward extension sections
56, 58 and the cross member 60 form a slot or aperture 62 into
which a lifting or leveraging device is inserted for lifting the
combined drywall installation apparatus 10 and sheet of drywall.
Those skilled in the art will understand that any configuration of
a base or foot piece may be utilized so long as a lifting or
leveraging force can be applied to the drywall installation
apparatus 10.
[0028] An alternative embodiment of the present invention is shown
in FIGS. 4-5. To install a piece of sheetrock or drywall on a lower
portion of a stud wall, a specialized, alternative embodiment of
the drywall installation apparatus may be used. As shown in FIG. 4,
a support assembly 70 is shown, which includes a support 72 in the
form of a trough or cradle, which comprises a front wall 74, a
bottom wall 76, and a back wall 78. A cantilevered support arm 80
holds the trough 72 away from the lower rod 20. A stabilizing arm
or gusset plate 82 interconnects the cantilevered extension arm 80
and the telescoping tubular section 84. In a preferred embodiment,
the brace or gusset plate 82 is welded to the extension arm 80 and
the tubular sleeve portion 84. The tubular section 84 includes an
aperture 86 through which an appropriate pin assembly 87 (identical
to pin assemblies 28,30 shown and described in FIGS. 1 and 2) is
inserted, depending on the desired height of the trough 72.
[0029] A stand assembly 90 is installed over the lower rod 20 and
secured in place through aperture 96 in tubular section 94 with an
appropriate pin assembly 97 (identical to pin assemblies 28, 30
shown and described in FIGS. 1 and 2) at the lowermost aperture 24
(FIG. 3) formed in the lower rod 20. The stand assembly 90 is
intended to remain in the lowermost position relative to lower rod
20 to aid in supporting the drywall installation apparatus and the
sheet of drywall it holds. The stand assembly 90 includes a
downwardly extending stand piece 92, which terminates at an angled
edge 93 corresponding to the orientation of the floor, and a
tubular, telescoping sleeve section 94, which slides over lower rod
20. It should be noted that the foot piece 54 of the base 16 in the
alternative embodiment shown in FIGS. 4 and 5 is substantially
identical to the foot piece and base described with respect to FIG.
3. The foot piece 54 defines an appropriately sized aperture 62
through which a lifting or leveraging device can be inserted for
lifting the drywall installation apparatus 68 and the piece of
drywall it is holding into an appropriate position on a stud
wall.
[0030] FIG. 6 shows the operation of the drywall installation
apparatus 10 shown and described with respect to FIGS. 1 and 3.
Generally speaking, the embodiment of FIGS. 1-3 is utilized for
installing a sheet of drywall or wallboard 100 on a stud wall 102.
The stud wall will comprise a plurality of vertically aligned studs
104 secured between a top cross piece (not shown) and a bottom
cross piece 106. When installing a sheet of drywall 100 to an upper
portion of the stud wall 102, it can be difficult for a single
person to hold the drywall in place while anchoring the piece of
drywall to the stud wall. As shown in FIG. 6 the alignment member
or stud guide 46 is then positioned over one of the studs 104,
depending on the desired location for installing the sheet of
drywall. Thereafter, an edge of the sheet of drywall 100 is placed
inside the support assembly 14 of the installation apparatus 10.
The overall length of the drywall installation apparatus 10 will
have previously been adjusted using the telescoping extension
section 12 to the appropriate size by moving the upper rod 22 and
lower rod 20 relative to the tubular sleeve 18 and secured in place
by pin assemblies 28 and 30. When the sheet of drywall 100 is
appropriately positioned inside the support assembly 14, a
conventional roll jack 110 is positioned so that the front edge of
the roll jack 112 is inserted through the aperture 62 formed in the
base or foot assembly 54. Thereafter, the installer's foot is
placed on the rear end 114 of the roll jack and, with the weight of
the installer, the roll jack 110 pivots about the fulcrum (roller
116) which places an upwardly leveraging force on the drywall
installation apparatus 10 to place the sheet of drywall 100 in the
appropriate position for fastening. Since the installer's foot is
used to raise and hold the sheet of drywall 100 to the appropriate
position for installation, and since the stud guide 46 prevents the
device 10 from tipping from one side to another, the installer can
easily use both hands to secure the fasteners through the sheet of
drywall 100 and into the stud wall 104. The installation apparatus
10 as shown in FIG. 6 is intended to aid in installing drywall at
upper reaches of a stud wall.
[0031] FIG. 7 shows the operation of the alternative embodiment of
the drywall installation apparatus 68. In general, the embodiment
of the drywall installation apparatus 68 shown and described with
respect to FIGS. 4 and 5, and in operation shown in FIG. 7 is
intended to be utilized for installing a sheet of drywall 100 on
lower areas of a stud wall 102. The installation apparatus 68 is
positioned to hold a piece of drywall 100 in the desired location
for installation with the exception of some minor vertical
positioning. The lower edge of the sheet of drywall 100 is
positioned inside the support or support assembly 72 in the form of
a cradle or trough. Prior to placing the piece of drywall 100 into
the trough 72 of the support assembly 70, the height of the trough
72 is adjusted by moving the tubular sleeve portion 84 relative to
the lower rod 20 and secured in place by inserting pin assembly 87
through the aperture 86 (FIGS. 4 and 5) of the tubular sleeve
section 84 and through one of the apertures 24 formed in the lower
rod 20. The stand assembly 90 assists in holding the entire
installation apparatus 68 in position, including the piece of
drywall 100, prior to installing the sheet of drywall 100. A
conventional roll jack 110, similar to the one shown in FIG. 6, is
positioned and utilized to create an upward lifting or leveraging
force on the drywall installation apparatus 68 so that the operator
can utilize his or her hands and secure the piece of drywall 100 in
the appropriate position on stud wall 102. It will be noted that
the alternative embodiment of the drywall installation apparatus 68
is utilized such that the support assembly 70 remains between the
studs 104 during installation. Accordingly, no modifications are
necessary to the front end of the trough (such as the gap 45 shown
in the embodiment of FIGS. 1-3) to allow for flush positioning of
the sheet of drywall 100 on the studs 104.
[0032] While this invention has been described with reference to
certain specific embodiments and examples, it will be recognized by
those skilled in the art that many variations are possible without
departing from the scope and spirit of this invention. The
invention, as described by the claims, is intended to cover all
changes and modifications of the invention which do not depart from
the spirit of the invention. The words "including" and "having," as
used in the written description and the claims, shall have the same
meaning as the word "comprising."
