Description
TECHNICAL FIELD OF THE INVENTION
[0001] This invention relates, in general, to a personal cooling
system and, in particular, to a clothing cooling system, and method
for use of the same, for providing temporary cooling comfort to a
human wearer in order to facilitate cooling the wearer, in part, by
temperature control.
BACKGROUND OF THE INVENTION
[0002] Hyperthermia is an elevated body temperature due to failed
thermoregulation. On a cold day, elevated body temperature can help
the body maintain an optimal temperature. On a hot day, however,
hyperthermia can occur when the body produces or absorbs more heat
than can be dissipated. When the elevated body temperatures are
sufficiently high, hyperthermia is a medical emergency and requires
immediate treatment to prevent disability or death.
[0003] Hypothermia is typically experienced during physical
exertion in a hot environment. Wearing a personal cooling system
can prevent or mitigate the risks of hypothermia in such
conditions. Important factors to the selection of a personal
cooling system are weight and convenience. Existing personal
cooling systems that utilize heat pumps or cold packs are
encumbering, and particularly so, during physical exertion. There
continues to be a need for advances in personal cooling
systems.
SUMMARY OF THE INVENTION
[0004] It would be advantageous to achieve a cooling clothing
system and method for use of the same for personal cooling. It
would also be desirable to enable temporary cooling comfort to a
human wearer without unnecessarily encumbering the human wearer. To
better address one or more of these concerns, in one aspect of the
invention, one embodiment of a system is presented having article
of clothing and belt that correspond to the human skeletal system
to mitigate encumbered movement. Multiple sealable pouches are
formed within the article of clothing and belt. Each of the
respective exterior sealable pouches defines a volume for
selectively accepting a pack of heat exchange material. The heat
exchange material includes a melting/freezing temperature in a
temperature range of about 50.degree. F. and about 70.degree. F.
During use, thermal gradients are formed from the skin of the human
wearer to the heat exchange material, thereby providing temporary
cooling comfort to the human wearer. These and other aspects of the
invention will be apparent from and elucidated with reference to
the embodiment(s) described hereinafter.

DETAILED DESCRIPTION OF THE INVENTION
[0013] While the making and using of various embodiments of the
present invention are discussed in detail below, it should be
appreciated that the present invention provides many applicable
inventive concepts which can be embodied in a wide variety of
specific contexts. The specific embodiments discussed herein are
merely illustrative of specific ways to make and use the invention,
and do not delimit the scope of the present invention.
[0014] Referring initially to FIGS. 1 through 4, therein is
depicted a cooling clothing system that is schematically
illustrated and generally designated 10. The cooling clothing
system 10 provides temporary cooling comfort to a human wearer 12
and the cooling clothing system 10 includes an article of clothing
14, depicted as a vest, and a belt 16. It should be appreciated,
however, that the cooling clothing system 10 may be utilized with
an animal as well after appropriate modification.
[0015] The vest 14, which also may be a shirt, includes a chest
enclosing portion 18 and a back enclosing portion 20 connected by
adjustable straps 22, 24 and fasteners 26, 28, both of which may be
buckles or Velcro-type attachment elements. The belt 16 cinches
about the waist and may be adjusted by a fastener 30. When worn,
the vest 14 and belt 16 are snug but comfortable and do not
encumber movement. Stated another way, during use, the article of
clothing 14 and belt correspond to the human skeletal system to
mitigate encumbered movement of the human wearer 12 during
activity. More particularly, the vest 14 and belt 16 use biomimicry
to respond to the structure and the corresponding movement of the
human skeletal system. The thoracic cavity (or chest cavity) is the
chamber of the human body is protected by the thoracic wall, which
includes the thoracic cage and associated skin, muscle, and
fascia.
[0016] The thoracic cage or rib cage is a component of the human
respiratory system as the thoracic cavity contains the lungs which
must have sufficient space for inhaling and exhaling air. On the
other hand, the pelvic cavity is a body cavity that is bound by the
bones of the pelvis and which primarily contains reproductive
organs, the urinary bladder, and the rectum. The pelvic cavity
plays a large role in the movement and bipedal locomotion.
[0017] As will be discussed in further detail hereinbelow, the vest
14 and belt 16 of the cooling clothing system 10 furnish temporary
cooling comfort to a human wearer 12 in order to facilitate cooling
the human wearer 12, in part, by temperature control. In one
embodiment, the two part construction of the vest 14 and belt 16
corresponds to the chest and pelvic cavities to provide cooling
close to critical internal organs while not encumbering movement or
breathing. The belt 16 also covers the stomach and cools the
internal organs. That is, this arrangement allows for physical
movement without binding by providing for the selective placement
of heat exchange packs based on the application or sport.
[0018] Referring again to FIGS. 1 through 4, more particularly, the
article of clothing 14 includes chest 18, left and right shoulder
32, 34, and back 20 regions. The chest enclosing portion 18 and the
back enclosing portion 20 include adjustably joined front and rear
layers of fabric having insides and outsides, which are configured
to support thermal communication with skin of the human wearer in
order to conform thereto such that physical movement is
unencumbered. The chest enclosing portion 18 and the back enclosing
portion 20 are configured such that the inside is positioned to
contact human skin and the outside presents a substantially
continuous surface. In one implementation, the front and rear
layers of fabric may be a stretchability sufficient to permit the
article of clothing to fluctuate with respect to the body of the
human wearer 12 and/or the front and rear layers of fabric may
include stitching or a porous and hydrophilic material. Closure
mechanisms 32, 34, which may be Velcro-type attachments, may join
and separate the front and rear layers of fabric. The adjustably
joined front and rear layers of fabric 18, 20 may include a 250
thread count cotton, for example.
[0019] Respective exterior front sealable pouches 40, 42 are formed
on the outside of the front layer of the fabric proximate to the
left and right shoulder regions of the human wearer 12. Each of the
respective exterior sealable pouches 40, 42 define a volume for
selectively accepting a pack of heat exchange material 70, which
will be discussed in greater detail hereinbelow. A closure
mechanism, such as Velcro', for example, may provide for the
opening and closing of the sealable pouches (See FIGS. 6A & 6B,
82-86). Further, it should be appreciated that the pouches may be
different sizes and shapes depending on location in the cooling
clothing system. Alternatively, certain pouches may be removed or
extra pouches added. For example, the respective exterior sealable
pouches 40, 42 may not be included. Moreover, the cooling clothing
system 10 allows for the selective application of the packs of heat
exchange material based on the sport or application. As each sport
or application has different movements, the packs of heat exchange
material are selectively placed so not to create hindrance.
[0020] An interior front sealable pouch 44 is formed on the inside
of the front layer of the fabric proximate to the chest region. The
interior front sealable pouch 44 defines a volume for accepting a
pack of the heat exchange material. Interior rear sealable pouches
46, 48, 50, 52 are formed on the inside of the rear layer of the
fabric proximate to the back region. Each of these interior rear
sealable pouches 46, 48, 50, 52 also define a volume for accepting
a pack of the heat exchange material. In one embodiment, at least
one of the exterior front sealable pouches 40, 42, interior front
sealable pouch 44, and interior rear sealable pouches 46-52
comprises a plurality of overlapping pouches, each of the plurality
of vertically overlapping pouches defining adjacent volumes for
selectively accepting overlapping packs of the heat exchange
material. In particular, such overlapping pouches may be used to
mimic the contour of the back on the back enclosing portion 20.
[0021] Respective closure mechanism pairs 43, 45 and 47, 49 further
provide for height adjustment and proper fit. As depicted in the
illustrated embodiment, a closure mechanism, such as Velcro.RTM.
provides for the opening, closing, and adjusting of the closure
mechanism pairs 43, 45 and 47, 49, wherein closure mechanisms 43,
47 are associated with the chest portion 18 and the corresponding
closure mechanisms 45, 49 are associated with the back portion
20.
[0022] The belt 16 includes multiple interior and/or exterior waist
sealable pouches, such as pouch 60, formed on an inside or outside
of the belt 16. The cinching mechanism 30 adjustably secures the
belt to the human wearer. Similar to the vest 14, each of the
sealable pouches 60 define a volume for accepting a pack of the
heat exchange material. It should be appreciated that although
particular pouch placements are presented, other pouch placements
are within the teachings of the present invention. Moreover, which
pouches will receive packs of the heat exchange material depends on
the particular activity and sport to be undertaken and the physical
structure of the human wearer.
[0023] The sealable pouches 40-52 formed on the front and rear
layers of fabric 18, 20 selectively accept a pack of the heat
exchange material 70. The variety of locations provided by the
sealable pouches 40-52 enable the selection of specific locations
depending on the sport or application. In one embodiment, each
sealable pouch 40-52 that defines a volume includes a layer of
removable insulation, such as neoprene or other waterproof
material, on the exterior of the layers of fabric that keeps the
packs insulated from the outside. Each layer of removable
insulation may be independently removed and reapplied, as
appropriate. That is, in one embodiment, the insulation is only
used as needed when and where packs of heat exchange material are
placed. During use, thermal gradients are formed from the skin of
the human wearer to the deposits or packs of heat exchange
material, thereby providing temporary cooling comfort to the human
wearer.
[0024] Referring to FIG. 5, the packs of the heat exchange material
70 include a melting/freezing temperature in a temperature range of
about 50.degree. F. and about 70.degree. F. In one implementation,
the melting/freezing temperature is about 60.degree. F. The heat
exchange material 70 changes phase through substantially direct
contact with the wearer from solid to liquid within the practical
temperature range by absorbing heat from the wearer's body. By way
of example, and not by way of limitation, the heat exchange
material 70 may be a phase change material such as n-Hexadecane or
n-Tetradecane. Moreover, depending on the application and placement
the packs of heat exchange material 70 may have different sizes and
shapes.
[0025] With reference to FIGS. 6A and 6B, the cooling clothing
system 10 may be worn during strenuous physical activity in a harsh
environment where it will be difficult for the body to
self-thermoregulate. As shown, the article of clothing 14 and the
belt are adjacent to the skin 80 of the human wearer 12. Packs of
heat exchange material 70 are located within exterior front
sealable pouch 40, interior front sealable pouch 44, and belt pouch
60 by way of respective sealable openings 82, 84, 86. As previously
discussed, thermal gradients are formed from the skin 80 of the
human wearer 12 to the packs of heat exchange material 70, thereby
providing temporary cooling comfort to the human wearer. With
particular attention to a comparison between FIGS. 6A and 6B,
during physical activity (FIG. 6B), heat (H) is transferred from
the human wearer to the pack of heat exchange material, which
absorbs the heat and changes phase. The enthalpy of vaporization
(.DELTA.H.sub.VAP) depicts the heat transfer from the skin of the
human wearer to the environment by way of absorption of the heat by
the packs of heat exchange material, which may change phase from a
solid (S) to a liquid (L), as represented by the state transition
indication (S/L). In this manner, the cooling system 10 permits a
person or animal to exercise in hot weather without
overheating.
[0026] Moreover, the article of clothing 14 does not stay skin
tight. Rather, the article of clothing fluctuates, as shown by the
letter (F), in and out of contact with the skin. In particular, the
packs of heat exchange material 70 proximate contact to the skin of
the body of the human wearer and quickly absorb heat (H), then the
packs of heat exchange material 70 swing away from the body of the
wearer 12 to allow air and evaporation (A) to occur. In one
implementation, the fluctuation may be approximately inch or more.
The fluctuation (F) cools the human wearer 12 further.
[0027] While this invention has been described with reference to
illustrative embodiments, this description is not intended to be
construed in a limiting sense. Various modifications and
combinations of the illustrative embodiments as well as other
embodiments of the invention, will be apparent to persons skilled
in the art upon reference to the description. It is, therefore,
intended that the appended claims encompass any such modifications
or embodiments.
