Tire Inflator Tool
Abstract
The Tire Inflator Tool (T.I.T.) is used to inflate air filled
tires or devices to a constant and precise PSI automatically. The
device is preset to a certain pressure such as 35 psi used almost
exclusively in automobile tires and bicycle tires. T.I.T. can also
be used for other psi recommendations by changing the spring
specifications making the T.I.T. application unlimited in the use
of air inflated tires or devices. T.I.T. has a moulded body with
three intersecting outlets. On one outlet It has a tire valve stem
that is used to attach the air pump or compressed air hose to. On
the second outlet it has a hose with a standard nozzle used to
attach to the valve stem of the tire or device your filling with
air. The third outlet has a spring loaded pressure release valve
that is opened automatically when extra air pressure is achieved
then closes automatically to a preset and constant maintained
pressure.

Claims
1. The T.I.T. is an automatic pressure setting device that uses an
air release system to achieve a designated pressure for
inflatables.
2. The T.I.T. as in claim 1 is easy to use.
3. The T.I.T. as in claim 1 prevents premature wear and blowouts of
inflatables, such as tires due to over or under inflation,
promoting safety and a green environment.
Description
[0001] This application claims the benefit of the earlier filing
date of Nov. 30, 2010 of PROVISIONAL APPLICATION No. 61418259.
DESCRIPTION
[0002] The Tire Inflator Tool (T.I.T.) (FIG. 1) was invented to
make the filling of air inflated tires and devices easier. The
T.I.T. uses a pressure release valve that is preset to a designated
pressure. Although invented for automobile tire use, the T.I.T. can
be manufactured to any pressure requirement for use on bicycle,
trailer, motorcycle or scooter tires and basket or soccer balls.
The T.I.T. would stay the same while different springs would be
used in each application. Alternatively a T.I.T. could be made
using a digital type mechanism that would use a battery or power
source. This version would be intended for a more experienced user
who would have the knowledge to be able to set different pressures
using a digital type display for different applications. This
version would use the same principle design except switches and/or
relays would manipulate the stopper allowing a single T.I.T.
version that could be used for multiple inflating applications.
What sets the T.I.T. apart is its ease of use for all people.
Common tire gauges use air to measure the pressure with the user
responsible for achieving the correct pressure through a trial and
error process of inflating and removing air. Whereas the T.I.T.
uses air to set the tire pressure automatically to a constant
designated precise pressure such as 35 psi used commonly on
automobile tires. When inflating tires a recommended psi needs to
be achieved. To date a person must use a tire gauge that has
multiple measurements even though most all automobile tires use 35
psi. Achieving the precise pressure using a tire gauge is a trial
and error process where the user must inflate or deflate air,
continuously checking the pressure. Even when this is achieved it's
very difficult to fill all the tires the same. The gauges can be
hard to read and hard to understand. Comparing the T.I.T. to other
devices is difficult since there are no other devices like it in
the current marketplace. For all the above noted reasons the T.I.T.
will make tire type gauges and that process obsolete. Because it
has a preset pressure setting and works automatically it makes the
process of achieving correct tire pressure simple. The T.I.T. works
in conjunction with air pumps such as those commonly found at gas
stations or portable air compressors for home use. The process is
the same for all applications. First you connect the T.I.T. flip
nozzle (or alternatively other attachments for filling could be
used for example a needle type for filling footballs or soccer
balls or other types of standard fittings used for inflating tire
valve stems) (14, FIG. 1) to the valve stem of the tire you are
filling, you then turn on the air compressor line and press the air
line to the T.I.T. valve stem (or alternatively other fittings
could be used to connect the T.I.T. directly to an air hose for use
in areas where the T.I.T. is used in a more permanent environment
such as a repair garage) (7, FIG. 1). Continue to fill tire until
pressure relief valve (4, FIG. 1) opens and starts to release air
(5, FIG. 1), remove air compressor line from T.I.T. valve stem (7,
FIG. 1) and wait for the air relief valve (4, FIG. 1) to stop
omitting air by closing (FIG. 6). At this point the tire being
inflated will be set to the exact pressure. The only requirement
for using the T.I.T. is knowing the psi of the tire or device being
inflated and the general knowledge needed to use an air compressor
as described above.
[0003] The T.I.T. is composed of a moulded brass body (10, FIG. 1)
with three intersecting outlets (6,9,11, FIG. 2). The first outlet
(9, FIG. 2) has a standard tire valve stem (7, FIG. 2) held on with
a compression fitting (8, FIG. 2). The second outlet (11, FIG. 2)
has a rubber hose (13, FIG. 1) and flip nozzle (14, FIG. 1) that
can been seen used on most bicycle pumps and is also held on by a
compression fitting (12, FIG. 1). The third outlet (6, FIG. 2) is
the pressure release air valve (4, FIG. 2) that is threaded and
screwed into place (4, FIG. 2). The air relief valve stem is a
standard type with a hollowed body (4, FIG. 6), a spring (3, FIG.
3), a stopper (1, FIG. 4) and a cap (2, FIG. 5). Note that all
springs (3, FIG. 3) used in this T.I.T. have to be engineered to an
absolute specification in order to achieve the specific psi
requirements for each application. FIG. 6 illustrates a
representation of a compound type injection moulded body (15, FIG.
6) that will make manufacturing the final T.I.T. cheaper and
faster. Although the automatic releasing and closing of air will
not change, the general spirit of the design will remain the same
and changes will occur to support manufacturing.
