Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The following application is a based on and claims the
priority benefit of U.S. provisional application Ser. No.
62/515,591 filed Jun. 6, 2017 currently co-pending; the entire
content of which is incorporated by reference.
BACKGROUND OF THE INVENTION
[0002] A drywall mud applicator handle is provided. The drywall mud
applicator handle has a generally cylindrical exterior tube having
a generally hollow interior having components. The generally hollow
interior of the handle contains a second hollow tube (therein
having a reduced weight over existing solid rods) for activating
the drywall mud applicator. The second hollow tube lacks any bends
and may therein be reversed to dramatically increase the life span
of the second hollow tube by altering the wear and tear on the tube
evenly.
[0003] Drywall mud applicators having interior components have been
invented in the past. For example, U.S. Pat. No. 5,902,451 to
O'Mara discloses an applicator for applying joint compound or mud
to wallboard has six embodiments with a head, a mud outlet and a
mud hose. The applicator has a handle and a control valve for
controlling the flow of mud. Each embodiment also has a screed on
the head above the mud outlet which extends beyond the end of the
head. The screed smoothes down the mud applied to the wall and
wipes away any excess mud. The first embodiment has a fan-shaped
head with baffles to define multiple flow ports. The second and
third embodiments have a rectangular head and a pair of retractable
corner stops which align the mud outlets flush with the corners of
drywall sections. The third embodiment adds a dispersion mechanism
for varying the width of the outlet. The fourth embodiment of the
applicator has a wedge-shaped head and a V-shaped screed with flow
ports in the sidewalls that are designed to apply mud to
right-angled corners. The control valve of the final embodiment has
a cylindrical core with a slot which selectively aligns with a slot
in the mud chamber. The control valve is operated by a
spring-biased lever which contacts the wall. The lever has a pair
of arms and a wheel on each arm. The arms extend from an outer edge
of the control valve past the mud outlet to automatically open flow
when the head is pressed against the wall.
[0004] Further, U.S. Pat. No. 5,545,287 to Carlson discloses a tool
for finishing joints at flat surfaces or corners of wallboard walls
after adhesive and tape have been applied are attached to the
applicator tool by a rotatable yoke connection near the roller of
the applicator so that the finishing tool will follow the
applicator tool. The finishing tool includes a roller rotatable
about an axle for embedding tape into the adhesive. Frame structure
rotatably supported on the roller axle is provided with trowel
means having a working surface moving parallel to the wallboard
surface and placed close to the roller, at least on the sides, to
spread adhesive pressed from under the tape back over the tape.
Finishing means attached to the frame structure to follow the
trowel collects the excess adhesive and distributes it in a smooth
surface generally in the plane of the wallboard, filling in any
voids left by trowel action. A cylindrical roller is used for
joints in flat wallboard. A finishing tool having a complex roller
having a base-to-base dual right frustoconcial form with an axle on
the common axes of the cones and conical surfaces meeting at an
angle of no more than 90.degree is used in the corner.
[0005] However, these drywall mud applicators do not provide a
drywall mud applicator having a hollow interior second tube which
is easy to use, efficient and inexpensive as is disclosed in the
present application.
SUMMARY OF THE INVENTION
[0006] A drywall mud applicator handle is provided. The drywall mud
applicator handle has a generally cylindrical exterior tube having
a generally hollow interior having components. The generally hollow
interior of the handle contains a second hollow tube (therein
having a reduced weight over existing solid rods) for activating
the drywall mud applicator. The second hollow tube lacks any bends
and may therein be reversed to dramatically increase the life span
of the second hollow tube by altering the wear and tear on the tube
evenly.
[0007] An advantage of the present drywall applicator handle is
that life span of the interior second hollow tube (the "activator
component") of the handle may be generally doubled over existing
drywall applicators.
[0008] And another advantage of the present drywall applicator
handle is that the present device may be less expensive to
produce.
[0009] Yet another advantage of the present drywall applicator
handle is that the present device is lighter and easier to use.
[0010] For a more complete understanding of the above listed
features and advantages of the present drywall mud applicator
handle device reference should be made to the following detailed
description of the preferred embodiments. Further, additional
features and advantages of the invention are described in, and will
be apparent from, the detailed description of the preferred
embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] A drywall mud applicator handle is provided. The drywall mud
applicator handle has a generally cylindrical exterior tube having
a generally hollow interior having components. The generally hollow
interior of the handle contains a second hollow tube (therein
having a reduced weight over existing solid rods) for activating
the drywall mud applicator. The second hollow tube lacks any bends
and may therein be reversed to dramatically increase the life span
of the second hollow tube by altering the wear and tear on the tube
evenly.
[0016] Referring first to FIG. 2, an embodiment, a drywall mud
applicator handle 1 is provided. The handle 1 may have a first end
2, a second end 3 (FIG. 4), a generally cylindrical side 4 and a
generally hollow interior 5. Within the generally hollow interior 5
of the handle 1 may be an elongated activator tube 10, wherein the
elongated activator tube 10 has a first end 11 and a second end
(not shown). A pull rod 85 (FIGS. 1 and 2) may be connected to a
trigger mechanism for a person to control with his/her hands.
Typically, elongated activator tubes 10 of existing prior art
drywall mud applicator handles are solid. As a result, the overall
weight and cost of production of the device is increased over the
present elongated activator tube 10 as a result of the present tube
10 being hollow. Located at the first end 11 of the elongated
activator tube 10 may be a "pinched" or flattened portion 90 (FIG.
3) which receives a pin 91 for activating the tip 100 of the
device.
[0017] In an embodiment, the pinched portion 90 of the elongated
activator tube 10 is located off-center from the tip 100 of the
device 1 as is illustrated in FIG. 2. In particular, a generally
flat connection unit 95 having rounded edges may connect the
pinched portion 90 of the first end 11 of the elongated activator
tube 10 to the tip 100 of the device by means of two pins 91 (one
at each end of the connection unit 95). The pins 91 may allow the
connection unit 95 to rotate; therein allowing the first end 11 of
the elongated activator tube 10 to move slightly closer to or away
from the tip 100. Thus, the two pins 91 act as pivots between the
elongated activator tube 10 and the tip 100. In an embodiment, the
tip 100 locks a drywall mud applicator box (not shown) and secures
the same for use.
[0018] In an alternative embodiment, as illustrated in FIG. 4, the
second end 3 of the drywall mud applicator handle 1 may have a
threaded portion 50 which correspondingly is secured into a
threaded portion 51 of a second unit 52. The second unit 52 may
allow for the length of the overall handle 1 to be extended so as
to allow a user to reach higher surfaces on a wall. The second unit
52 may be easily added or removed from the second end 3 of the
handle 1, depending on the needed use.
[0019] The present elongated activator tube 10 may further be
straight, whereas existing prior art activator tubes have a bend
near 40 the front end (see FIG. 1). The bend of existing prior art
elongated activator tubes allows the tube to extend through an
opening 30 which is off-centered on an end cap 35 of the handle 1.
As a result, the elongated activator tube of existing prior art
devices may not be flipped over as the bended portion will therein
not be directed into the off-centered opening 30 in the end cap
35.
[0020] The present elongated activator tube 10 may be flipped over
as a result of being straight (See FIG. 2). The straight elongated
activator tube 10 may extend through a centered opening 30 of the
end cap 35 of the present device 1 as is shown in FIG. 2. As a
result, the elongated activator tube 10 of the present device may
be flipped so that wear and tear on the elongated activator tube 10
may be evenly divided. In particular, in normal use in existing
activator rods (#10 of FIG. 1), a washer 75 digs into the rod more
heavily on one side than the other side of the elongated rod. More
specifically, a washer 75 activated by a pull rod 85 causes the
washer 75 to unevenly apply pressure to one side of the elongated
activator tube 10. This causes uneven wear and tear. The present
device allows for a quick flipping of the elongated activator tube
10 so that the elongated activator tube 10 experiences even wear
and tear. In an alternative embodiment, the pull rod 85 may be a
stainless steel band, as opposed to a rod, so as to the overall
reduce weight of the device. For clarity purposes, as described
above, the present elongated activator tube 10 may be flipped so
that the #90 on FIG. 3 would then be located next to the #95 in
FIG. 3 once flipped.
[0021] Although embodiments of the invention are shown and
described therein, it should be understood that various changes and
modifications to the presently preferred embodiments will be
apparent to those skilled in the art. Such changes and
modifications may be made without departing from the spirit and
scope of the invention and without diminishing its attendant
advantages.
