MULTI-T

MULTI-T

Abrégé anglais

The present invention is used to hold sheetrock in an
elevated position, while it is being secured. This device
has an upper horizontal tubing platform T that comes in
contact with the sheetrock. This platform is covered
with a foam rubber to protect and secure the sheetrock.
The lower verticle tubing comes in contact with the
floor. Where the tubing meets the floor, a rubber boot
is secured. The cupling under the boot is adjustable to
make up the difference in the holes in the middle tubing
if needed. This unit is telescopic in the way that one
tube slides over the other as it goes through a selection
of holes, which choses the height of the ceiling. Also
this device comes apart below the two upper support
braces. By backing off the handle attachment you now
have an extension handle. Also this extension handle
comes apart at screw safety lock nut. Now you have two
single handles. Attachments can be used on these exten-
sion handles to do various other jobs such as, painting
sanding, and washing windows etc. This device is a MULTI
use tool,and it can be easily disassembled and stored
away for further use.

Revendications

Claims
The embodiments of the invention in which an ex-
clusive property or privilege is claimed are defined as
follows:"
Claim (1) This is a device that will hold up sheetrock
while it is being secured to the ceiling.
There is an upper horizontal platform T that
is padded with foam rubber to protect the
sheetrock as well as keeping it from moving
around. This pad is secured with adhesive
glue.
Claim (2) The device that is defined in claim (1) is
telescopic. The middle tube moves up and down
over the lower tube. Because it is telescopic
you can chose different heights for different
ceilings. While holding the lower tube press
in the spring button and turn the middle
section outer tube slightly. Now the spring
button is riding in between the middle section
outer tube and the lower tube. When desired
height of ceiling is reached line up arrows
that are marked on middle and lower tubing,
while holding the device at a slight angle.
Now let the button go into the nearest hole
while straighten up the device vertically to
hold tension on the sheetrock. Now one end of
the sheetrock is secured for nailing.

Claim (3) This floor engaging part of the device is tel-
escopic. A rubber boot is glued to the cupling.
The cupling is threaded and it screws over the
inner lower tubing which is also threaded. This
telescopic boot will make up the difference
between the holes in the middle tubing.
Claim (4) Now referring to claim (1) the upper horizon-
tal platform T is strategicly electric welded
in five places to strengthen the support syst-
em.
Claim (5) The temporary support device used in enstall-
ing sheetrock to the ceiling, as in claim (2)
has a dual purpose which is one long extension
handle or two short extension handles. The
extension handle comes apart at the top of the
middle tubing, which is the handle attachment
nut. As exclaimed in claim (2), the extension
handle can go through a series of heights by
depressing the spring button. The extension
handle also comes apart at the screw safety
lock nut to make two shorter extension hand-
les by pressing in the spring button and
turning the lower inner tubing slightly and
pulling downward by backing off the safety
lock nut.
When your job is completed, Your MULTI-T
device can be disassembled and put away for
further use.

Backqround Of Invention
Field Of Invention
This invention relates to a manually operated device that
holds sheetrock to the ceiling while it is being installed.
Description Of Prior Art
Sheetrock installation is a job requiring more then one
person. A wooden T is a device that many have used in the past and
are still using today. This was made of two pieces of wood nailed
together. One long vertical piece meets the shorter horizontal one
in the center. This device damaged the sheetrock as well it is
very awkward to use and trying to acquire the right height seemed
like an endless chore.
Also there is a floor jack device for holding up sheetrock.
The device is very complicated to operate, plus big and bulky. The
price is very expensive and beyond the means of the average
person.
There are some devices on the market similar to mine, but
they are complicated, bulky, and expensive.
Summary Of Invention
I have found that my invention has overcome the disadvant-
ages of the prior art.
My invention is very lightweight, but yet strong enough to
hold heavy sheetrock. It is also inexpensive to manufacture. The
device is easy to handle, plus you won't need a course to operate
it. This device is not a dead item. When your ceiling is completed
the device can be changed into an extension handle by separating
the device below the upper platform braces. Now you can use this
extension handle for painting, sanding, and cleaning windows etc.

Description of The Preferred Embodiment
Referring to Fig. (1), A device for holding sheetrock to
the ceiling in accordance with the invention. It includes a
horizontal tubing platform T (3) that comes in contact with
the sheetrock, and is connected to an outer tube (6a) and
inner tube (10). These tubes are vertical and telescopic in
nature. The inner tube (10) is connected to the rubber boot (11).
This rubber boot (11) comes in contact with the floor.
Referring to Fig. (2), Comprises of horizontal tubing
platform T (3) that comes in contact with sheetrock as shown in
Fig. (1). This is covered with sponge rubber (2) which runs from
end to end on the upper horizontal platform T (3). In the upper
horizontal platform T (3) there are inserted plastic plugs (1) in
each end. Also there are welded upper support braces (4) running
at a 45 degree angle from vertical tubing (6a) to end of vertical
tubing (6a), just below upper support braces (4), opposite end to
horizontal T (3) is welded inside outermost tubing (6a) an extra
course thread nut (14) to accommodate threaded stock (15) which is
upper end of extension handle.

Referring to Fig. (3), Comprises of middle section (6b) and
is also the upper view of the extension handle as mentioned in
Fig. (2). In the middle section tubing (6b) are holes (7) drilled
at same intervals running vertically from below handle attachment
nut (13) to above screw safety lock nut (8). By pressing spring
button (5) the device will manually travel up or down vertically,
as you chose the hole (7) to the desired height of the ceiling
which is 7 to 10'. The upper view of the extension handle or
upper middle section (6b) consists of threaded stock (15) welded
into middle section tubing (6b). The handle attachment nut (13) is
slipped over threaded stock (15) so it does not cover any of the
threaded stock (15). Then set screw (8) is tightened into handle
nut (13) to secure it. Lower end of middle section (6b) running
vertically is threaded (9) to take screw safety lock nut (8).
Referring to Fig. (4), Is a vertical sectional view of lower
section which was mentioned in Fig. (3). It consists of a vertical
piece of tubing (10) which fits inside middle tubing (6b) in a
telescopic way as told in Fig. (1) The upper part of tubing (10)
has a hole (20) drilled in it. Spring button (5) with a hole
drilled in one end of it has a shoulder on it. The spring (19) is
set in the hole of the spring button (5). then set the spring (19)
which is set in the hole of the spring button (5) down the upper
part of tubing (10) till the spring button (5) goes into the hole
(20) so as the spring (19) runs Horizontally to let the button
come out through the hole (20). There by the shoulder on the
button (5) will not let the button (5) come out through the hole
(20). This spring button (5) goes out through the holes (7) in the
middle section (6b) as in Fig. (3) to make the device telescopic.
The lower part of tubing (10) is threaded (16) so it could take a
cupling (17). This adjusting boot (11) makes up the difference
between the holes (7) in the middle section (6b). Extra course
threaded stock (21) is welded into end of lower section tube (10)
opposition end to rubber boot (11).
