Grout Sealer Applicator
Abstract
The Grout Sealer Applicator is a plastic wand type tool used to
apply grout sealer. The applicator wand can be attached to the end
of a chemical sprayer trigger. The applicator has a long tubular
body with an angled brush at one end and a connection nut on the
other. The applicator shaft is hallow, allowing grout sealer to
flow from the nut end, through the shaft and into the brush. The
grout sealer applicator gives the user the ability to apply sealer
directly onto the grout surface in a standing position. The Grout
Sealer Applicator is a wand type tool used to apply grout sealer.
The applicator wand can be attached to the end of a compression
sprayer trigger. The applicator has a long tubular body with an
angled brush at one end and a connection nut on the other. The
applicator shaft is hallow, allowing grout sealer to flow from the
nut end, through the shaft and into the brush. The grout sealer
applicator gives the user the ability to apply sealer directly onto
the grout surface in a standing position.

Description
BACKGROUND OF THE INVENTION
[0001] This invention relates to grout sealer applicators. More
over it relates to devices used to apply grout sealer, such as
mechanical.
[0002] Typically grout sealer is applied with a paint roller or
brush. Usually poured directly onto the grout and tile, then
painted or rolled into the grout lines.
[0003] Grout sealer that is applied by brush is not only time
consuming but normally done on the knees of the user, in an
uncomfortable position.
[0004] If it is being rolled into the grout lines it is messy and
wasteful.
[0005] Therefore it would be very advantageous to remedy this
process and other problems related to the above.
[0006] The object of this invention is to give the user a
comfortable way to apply grout sealer accurately and without waste,
saving the user both time and money.
[0007] Another object of this invention is to give the user more
control over the amount of grout sealer being applied, minimizing
mess and clean up time.
SUMMARY OF THE INVENTION
[0008] To achieve the objects described in the above background the
grout sealer applicator wand should be designed as follows:
[0009] A wand designed to attach directly to the threaded end of
most or all chemical sprayer triggers. If needed a special threaded
adapter can be used with the applicator to fit other triggers.
[0010] The wand has a hole through the shaft that allows grout
sealer to flow from the connection nut into the brush end. From the
brush it is applied directly and accurately onto the grout surface,
keeping the sealer in between the lines and not on the tile.
[0011] The length of the applicator wand should be about 3 feet or
long enough that it can be used in a comfortable standing
position.
[0012] The adjustable switch goes from high to low setting.
Depending on the users speed and accuracy they can choose the
setting that best suits them. The switch is mounted into the brush
end housing, inline with the shaft hole.
[0013] The brush is angled to compensate the users own angle at
which they stand giving the brushes more surface contact. The brush
bristles should be of high to medium quality to ensure the
applicator can be used repeatedly and to ensure that no bristles
come loose during application of the sealer.
[0014] To prevent excessive pressure at the nut & trigger
connection and possibly stripping the threads; the body of the
grout sealer applicator wand should be strong, flexible but also
light weight.
[0015] The connection nut should have enough threads to compensate
for the length and weight of the wand, ensuring a good and strong
connection to the sprayer trigger.
[0016] If needed the connection nut can also contain an internal
o-ring to seat and seal the connection.
[0017] The grout sealer applicator wand could be designed with its
own chemical sprayer and trigger or as stated can be used with most
standard chemical sprayers and triggers.
[0018] The applicator pays for itself on jobs that are 800 square
feet or more of tile and can be stored and used every year that
sealer needs to be applied.
[0019] Leftover grout sealer can be saved in the sprayer reservoir
and used again. Only the brush needs to be washed after use.
[0020] A wand designed to attach directly to the threaded trigger
end of most, all or one compression sprayer. If needed a special
threaded adapter can be used with the applicator to fit most, all
or one compression sprayer triggers.
[0021] The grout sealer applicator wand could be designed with its
own compression sprayer and trigger or as stated can be used with
most standard compression sprayers and triggers.
BRIEF DESCRIPTION OF THE DRAWINGS
[0022] FIG. 1 is a side view of the Grout Sealer Wand, showing the
entire body of the applicator, the angle of the brush, the
adjustment switch and the connection nut end.
[0023] FIG. 2 is an angled view of the applicator brush end,
without the brush bristles or the selector switch.
[0024] FIG. 3 is an angled view of the applicator shaft, without
the connection nut or brush. This figure shows a detailed look at
the nut end of the shaft, without the connection nut.
[0025] FIG. 4 is a side view of the applicator connection nut and
threads.
[0026] FIG. 5 is a side view and an internal view of the high and
low selector switch.
[0027] FIG. 6 is a view of the grout sealer applicator wand in
action or working.
DETAILED DESCRIPTION OF THE INVENTION
[0028] Now to the drawings in which similar reference characters
indicate the corresponding parts throughout different views. First
we look at FIG. 1 position 1 which shows direction of sealer flow
through the middle of the applicator shaft, from nut end to brush
end. Next FIG. 1 position 2 points to the threads in the connection
nut. Then FIG. 1 position 3 points to the body or shaft of the
applicator wand. Next FIG. 1 position 4 shows the length of the
shaft to be about 3 feet. FIG. 1 position 5 points to the high and
low setting switch. FIG. 1 position 6 points to the hole at the
brush end where grout sealer flows out and into the brush bristles.
FIG. 1 position 7 points to the angled brush bristles.
[0029] Now looking to FIG. 2 position 1, which shows an o-ring
groove on the wall of the high and low selector slot. Next FIG. 2
position 2 shows the hole at the brush end, where the sealer will
flow out. FIG. 2 position 3 shows another hole, where the sealer
flows into the selector switch, then to the brush side and out the
brush end. FIG. 2 position 4 shows one the four small round
indentations used for locking the high and low selector switch into
position. The indentations should be evenly spaced to provide a
secure lock.
[0030] Next we look at FIG. 3 position 1 which shows the direction
of sealer flow through the hollow shaft of the applicator. Then
FIG. 3 position 2 points to the shaft of the grout sealer
applicator wand. FIG. 3 position 3 points to the hole at the nut
end of the applicator shaft. FIG. 3 position 4 shows an optional
o-ring that could be used at the nut end to provide a better
seal.
[0031] Now to FIG. 4 position 1 which shows the threads inside the
applicator connection nut. There should be enough threads to insure
a solid connection. FIG. 4 position 2 points to the overall length
of the applicator connection nut. Which should be about 1/2'' or
long enough to support the length and weight of the grout sealer
applicator wand without stripping the threads of the connection nut
or trigger.
[0032] Next FIG. 5 position 1 shows one of the four locking knobs
that should hold the selector switch into place. FIG. 5 position 2
points at the selector switch o-ring. FIG. 5 position 3 shows the
hole of the low side. FIG. 5 position 4 points to the larger hole
which is the high side. FIG. 5 position 5 shows an internal look at
the low side hole of the selector knob. FIG. 5 position 6 shows an
internal look at the high side hole of the selector knob.
[0033] In FIG. 6 position 1 shows the chemical sprayer pump and
reservoir. FIG. 6 position 2 shows an average person using the
grout sealer applicator wand in a comfortable standing position.
FIG. 6 position 3 points to the applicator wand making contact with
the grout lines.
