COOL COAT
Abstract
A thermal coat or garment for maintaining a person comfortably
cool, the garment comprising an article of clothing having a tube,
the tubular network comprising a passage containing water and other
chemicals such as Freon used in refrigerator mechanisms, and the
tubes having capillary openings through the wall thereof so to
permit the tube to evaporate outwardly, the evaporating operation
creating a cooling effect to a wearer.

Claims
What I now claim is:
1. In a cool coat, the combination of a thermal garment, said
thermal garment comprising an article of clothing, said article of
clothing including an inner wall and an outer wall, either one of
said walls being deformed so to form corrugations therein forming a
tubular network comprised of a plurality of interconnecting tubes
between said walls, and said walls having capillary openings
extending therethrough so to allow evaporation therethrough of a
liquid placed within said tubular network, said tubular network
being provided at one end with an inlet into which said liquid is
received into said tubular network, a rear side of said garment
being provided with a liquid reservoir, said reservoir being
connected by a tube to said tubular network, said tube being
intercepted by a hand operated pressure bulb located on the rear of
said garment for moving said liquid between said reservoir and said
tubular network, said coolant liquid comprising a mixture of water
and a refrigerant cooler consisting of Freon.
Description
This invention relates generally to thermal garments. More
specifically it relates to thermal garments for maintaining a
person in a comfortably cool condition.
A principle object of the present invention is to provide a cool
coat having a novel construction based upon the principles of
refrigeration wherein an evaporation of a liquid creates a cooling
state, and wherein the present invention does not employ any
mechanisms to create the evaporative action.
Another object of the present invention is to provide a cool coat
which in a modified form of the invention may include a hand
operated valve between a liquid reservoir and the coat so as to
move the cooling liquid into the tubular system or network after a
quantity thereof has evaporated during a cooling action.
Other objects of the present invention are to provide a cool coat
which is simple in design, inexpensive to manufacture, rugged in
construction, easy to use and efficient in operation.
These and other objects will be readily evident upon a study of the
following specification and the accompanying drawing wherein:
FIG. 1 is a perspective view of the present invention,
FIG. 2 is a fragmentary enlarged cross-sectional view taken on the
line 2--2 of FIG. 1 and showing the tube construction,
FIG. 3 is a further enlarged cross-sectional perspective view of
one of the tubes showing the capillary openings through the wall of
the tube so to effect an evaporation of liquid contained within the
tube, and
FIG. 4 is a rear elevation view of a modified design of the present
invention employing a hand operated valve and a liquid
reservoir.
Referring now to the drawing in detail, and more particularly to
FIGS. 1 to 3 at this time, the reference numeral 10 represents a
cool coat according to the present invention wherein there is a
garment 11 which may comprise a vest, as shown, or which may
otherwise comprise a coat, a pair of trousers or any other garment,
and which incorporates the present invention.
The garment 11 includes an inner wall 12 and an outer wall 13,
either one of the walls being configurated with corrugations so to
form a tubular network 14 comprised of interconnecting tubes 15.
One end of the tubes, as shown in FIG. 1 of the drawing, is
provided with an inlet 16 into which liquid may be received for
circulating throughout the tubular network 14.
The opposite end 17 of the tubular network is closed, as shown in
FIG. 1. It will thus be evident that the liquid is dispensed from
the tubular network by other means than an outlet, such means
comprising a plurality of capillary openings 18 extending through
the tubular walls, as shown in detail in FIG. 3 of the drawing.
Thus it will be evident that the liquid will evaporate from within
the tube and accordingly the tubular system will require
replacement of cooling liquid.
Such cooling liquid may comprise a mixture of water and a
refrigerant chemical such as Freon generally used in refrigeration
cooling systems.
In operative use, it will now be evident that when the tubular
network is filled with a coolant liquid, the same will evaporate
through the capillary openings 18, such evaporation causing a
lowering of temperature at the surface of the vessel or tubular
wall, and thus cooling off the wearer of the garment.
In FIG. 4 of the drawing, a slightly modified form of the present
invention is shown to comprise a garment 19 which is generally
similar to the garment illustrated in FIG. 1 of the drawing, but
wherein as shown in the rear view, there is a liquid reservoir 20
containing the coolant liquid, the reservoir being replenished by a
removable cap 21.
A manually operated pressure bulb 22 is mounted along a tube 23
communicating between the reservoir 20 and the tubular network 24.
The tubular network 24 comprises a generally like tubular system as
above described.
In the present form of the invention, the inlet 16 is not
necessary. When the pressure bulb is squeezed by hand, it will pump
the warm liquid, heated by the natural body warmth from the tubular
network to the reservoir and at the same time recirculate a fresh
cool refrigerant liquid from the reservoir back into the tubular
network.
Also thus as the liquid coolant is vaporized through the capillary
openings 18 of the tubes, the liquid may be replenished into the
network 24. It is to be noted that there may be provided a
T-configurated fitting 25 at the junction of the tube 23 and the
tubular network 24 so as to branch the liquid travel toward the
right and left side of the garment.
In one form of the invention, gravity may drain the fluid downward
to the reservoir 20 gradually after which a manual squeezing of the
pressure bulb 22 will cause the liquid to be again raised upwardly
into the tubular network.
Thus a continuous or almost continuous movement of the liquid will
aid in circulation thereof and thus aid in the cooling
operation.
Accordingly in one form of the invention, the pressure bulb may
contain two directional passages, whereas in another form of the
invention, the pressure bulb may include only a one-way valve so to
normally force the liquid upwardly.
