BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a garment and an air-conditioned garment.
2. Description of Related Art
[0002] In long-term exercise, it is important to cool a body before, during and/or after
exercise in preparation for a rise in body temperature. Cooling a body is important
because even short-term exercise may increase body temperature depending on a type
and contents of exercise.
[0003] A known garment improves a function to cool a body of a wearer during and/or after
exercise by increasing ventilation, etc. (e.g., Japanese Patent No.
6030812).
[0004] A known air-conditioned garment comprises, as auxiliary equipment that effectively
serves to cool a body by heat of vaporization of sweat:
a garment body made by sewing fabric having low ventilation;
a fan mounted at a lower portion of the garment body on a back side;
a power supply that supplies power to the fan; and
a power cable that electrically connects the power supply and the fan.
[0005] When the fan is operated, a large amount of air is taken into the garment body from
the fan. The taken air flows upward along a surface of a body or an underwear in space
between the garment body and the body or the underwear. The air is discharged outside
from the periphery of a collar and sleeves, for example. The air vaporizes sweat on
the body while flowing in the space between the garment body and the body or the underwear.
Heat of vaporization generated by vaporizing sweat cools the body (e.g., Japanese
Patent No.
4329118).
[0006] Another air-conditioned garment is provided with an air outlet for a belly to cool
not only a chest, a back, etc., but also the belly (e.g., Japanese Patent No.
6536674) .
[0007] During and/or after exercise, hands and surrounding portions sweat. It is desirable
that sweat is wiped off quickly because hand sweat affects sports such as tennis.
Excess sweat prevents vaporization and a decline in body temperature. Hand vessels,
called arteriovenous anastomoses, are said to bring a decline in body temperature.
[0008] However, in a case in which a garment is made of absorbent cloth, the cloth is so
thick that heat tends to stay inside. It often impairs a function to cool a wearer's
body. Thus, many of garment fabrics to be worn during and/or after exercise are less
absorbent. It is difficult for a wearer to wipe hand sweat sufficiently. The air-conditioned
garment utilizing the function of heat of vaporization of sweat for cooling a body
cools a chest, a back, a belly, etc. However, it cannot cool hands of a wearer and
cannot wipe hand sweat sufficiently.
SUMMARY OF THE INVENTION
[0009] An object of the present invention is to provide a garment and an air-conditioned
garment which cool hands of a wearer and which easily wipe hand sweat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0022] Hereinafter, embodiments of the present invention will be described with reference
to FIG. 1 to FIG. 4. However, the scope of the invention is not limited to the disclosed
embodiments. In the following, as a suitable example of the present invention, a case
in which a garment is an air-conditioned garment is described using figures. However,
the scope of the claims of the present invention is not limited thereto. The embodiments
described below can be modified in various ways within the scope of the claims of
the present invention.
[0023] In the following description, front, back, top, bottom, right and left sides respectively
correspond to those of a person wearing an air-conditioned garment 100.
FIRST EMBODIMENT
[0024] A first embodiment of the present invention is described with reference to FIG. 1
to FIG. 3.
1) Configuration of Embodiment
[0025] As shown in FIG. 1 to FIG. 3, the air-conditioned garment 100 according to the first
embodiment includes:
a garment body 1;
a fan 2 that introduces air into the garment body 1;
a power source 3 that supplies power to the fan 2; and
a connection cable 4 that connects the power source 3 and the fan 2.
[0026] The air-conditioned garment 100 allows air taken by the fan 2 into space between
the garment body 1 and a wearer's body to flow along a surface of the wearer's body
or an underwear. Thereby, the air-conditioned garment 100 vaporizes sweat on the body.
Heat of vaporization generated by vaporizing sweat cools the body.
I) Garment Body
[0027] As shown in FIG. 1 to FIG. 3, a garment cloth C forms the garment body 1 in a shape
that covers a trunk, arms and a head of a wearer. The garment cloth C does not breathe
or is breathable to the extent that the garment cloth C is inflated by introduction
of air through the fan 2. The garment cloth C is made of, for example, polyester,
a mix of polyester and cotton, nylon, or the like.
[0028] The garment body is a portion of the air-conditioned garment 100 excluding electrical
components such as the fan 2, the power source 3, the connection cable 4, etc., i.e.,
a portion having a function of a garment. The garment cloth is a portion of a sheet
that constitutes the garment, the portion covering a wearer's body and defining a
shape of the garment. The portion does not include additional parts that do not define
the shape of the garment, such as a sheet used for a pocket.
[0029] In FIG. 1 to FIG. 3, the garment body 1 has a shape of a jacket having three-quarter
sleeves. A shape of the garment body 1 is not limited thereto. The garment body 1
may have any shape that covers at least a portion of a wearer's body. For example,
the garment body 1 may not include a hood 14 that covers a head, and may have long
sleeves or short sleeves. Alternatively, the garment body 1 may be a sleeveless vest.
[0030] In the following explanation, an inner surface of the garment cloth C is a surface
facing a person when the person wears the garment body 1. An outer surface of the
garment cloth C is a surface facing outer space when a person wears the garment body
1, which is opposite to the inner surface. When a person wears the garment body 1,
the inner surface of the garment cloth C as well as portions on a side of the person
is on an inner side of the garment body 1. When a person wears the garment body 1,
the outer surface of the garment cloth C as well as portions outside of the garment
cloth C is on an outer side of the garment body 1.
[0031] As shown in FIG. 1 to FIG. 3, the garment body 1 includes a fastener 11, an air seal
12, fan holes 13, the hood 14, sleeve openings 15, power source holders 16, cable
eyelets 17, front openings 18, envelope members 19, and absorbers 20. Air taken in
by the fan 2 from the fan holes 13 is discharged from the sleeve openings 15 and a
hood opening 141 formed in the hood 14.
i) Fastener
[0032] The fastener 11 opens and closes a front of the garment body 1 when the air-conditioned
garment 100 is put on. As shown in FIG. 1 and FIG. 3, the front of the garment body
1 is divided into left and right portions. For example, a zipper, a hook-and-loop
fastener or the like is mounted on each edges of the divided portion so that the divided
portion is opened and closed. Thus, the fastener 11 is formed.
ii) Air Seal
[0033] As shown in FIG. 1 to FIG. 3, the air seal 12 squeezes a hem at the bottom of the
garment body 1 so that the hem adheres to a wearer's body. Thus, the air seal 12 prevents
air in space between the garment body 1 and the wearer's body from being leaked out
of the hem of the garment body 1.
[0034] In FIG. 1 to FIG. 3, the hem of the garment body 1 includes, as the air seal 12:
a cord guide around a wearer's body except a portion near the fastener 11;
a cord passed through the cord guide; and
a cord stopper provided at a portion of the cord coming of the cord guide.
[0035] The portion of the cord coming out of the cord guide is pulled, and then the cord
stopper is fixed. Thus, the hem of the garment body 1 adheres to a wearer's body.
However, the air seal 12 is not limited thereto. For example, the air seal 12 may
be formed at the hem of the garment body 1 by wrapping an elastic member, such as
a rubber cord, around a wearer's body.
iii) Fan Hole
[0036] As shown in FIG. 2 and FIG. 3, the fan hole 13 is a circular hole formed in a back
of the garment cloth C constituting the garment body 1. The fan hole 13 connects space
between the garment body 1 and a wearer's body with outer space of the garment body
1 when the air-conditioned garment 100 is worn.
[0037] A diameter of the fan hole 13 is substantially the same as that of the fan 2. The
fan 2 is inserted and mounted in the fan hole 13. External air is taken through the
fan hole 13 into the space between the garment body 1 and the wearer's body.
[0038] The periphery of the fan hole 13 is preferably reinforced, for example, by attaching
a flat annular member made of plastic or the like, or by folding back and sewing a
portion of the cloth of the garment body 1 around the fan hole 13.
[0039] A position of the fan hole 13 is not limited to the above. The fan hole 13 may be
formed on a lateral side, the front side, etc. of the garment body 1. The number of
the fan holes 13 is not limited to two, and may be less or more. The number of the
fans 2 to be mounted corresponds to the number of the fan holes 13.
iv) Hood
[0040] The hood 14 protrudes from the top of the garment body 1 to cover a head of a wearer.
The hood 14 has the hood opening 141 at a front position corresponding to a face of
a wearer. Sufficient space is saved even when a wearer wears a hat. A cord guide is
provided around the hood opening 141. A cord passes through the cord guide. A length
of a portion where the cord passes through the cord guide is adjusted using a cord
stopper or the like. Thus, a size of the hood opening 141 is changed.
v) Sleeve Opening
[0041] The sleeve opening 15 is an opening formed at the end of the sleeve of the garment
body 1. A wearer passes a hand through the sleeve opening 15 to let the hand out of
the garment body 1.
[0042] In the embodiment, the sleeve opening 15 and the hood opening 141 function as air
outlets. The air outlets allows air introduced into space between the garment body
1 and a wearer's body from the fan hole 13 by the fan 2 to flow along the wearer's
body or an underwear and to go out. A position of the air outlet is not limited thereto.
The air outlet may be formed at any other position as long as the air outlet allows
air introduced from the fan hole 13 to flow along a wearer's body or an underwear
and to go out.
vi) Power Source Holder
[0043] The power source holder 16 holds the power source 3 at a position where the power
source 3 can supply power to the fan 2 through the connection cable 4. As shown in
FIG. 1, the power source holder 16 may be a pocket that accommodates the power source
3 on the outer side of the garment body 1. In FIG. 1, the power source holder 16 is
formed at each of left and right positions in front of a chest of a wearer. However,
a position of the power source holder 16 is not limited thereto. The power source
holder 16 may be placed at any other position on the inner and outer sides of the
garment as long as the power source 3 can supply power to the fan 2 through the connection
cable 4.
[0044] In a case in which the power source 3 is on the outer side of the garment, a hole
(not shown) is formed so that the connection cable 4 connecting the power source 3
and the fan 2 passes through the hole.
vii) Cable Eyelet
[0045] As shown in FIG. 1 and FIG. 3, the cable eyelet 17 is a slit which is formed in the
garment cloth C to draw the connection cable 4 connecting the power source 3 and the
fan 2 from the outer side to the inner side of the garment body 1. The cable eyelet
17 is formed in the vicinity of each power source holder 16. A position of the cable
eyelet 17 is not limited to the positions shown in FIG. 1 and FIG. 3. However, to
shorten a portion of the connection cable 4 coming out of the garment body 1, the
cable eyelet 17 should be formed near the power source holder 16.
[0046] It is preferable to form piping at each edge of the slit as the cable eyelet 17 such
that piping at one edge overlaps with piping at the other edge. It prevents air leakage
from the cable eyelet 17.
viii) Front Opening
[0047] As shown in FIG. 1, the front opening 18 is a slit formed in the garment cloth C
in the front of the garment body 1. The front opening 18 is formed on each of left
and right sides of the fastener 11.
[0048] A wearer inserts a hand through the front opening 18 from the outer side to the inner
side of the garment body 1. In view of this, the front opening 18 is formed at a portion
which a wearer's hand can reach in the front of the garment body 1. The front opening
18 is large enough to pass a wearer's hand through the front opening 18. It is preferable
to form piping also at each edge of the slit as the front opening 18 such that piping
at one edge overlaps with piping at the other edge. It prevents air leakage from the
front opening 18.
ix) Envelope Member
[0049] As shown in FIG. 3, the envelope member 19 is formed to have a shape of an envelope
by overlapping two substantially square-shaped sheets, joining the sheet edges on
two opposite sides, and forming an opening on the other two opposite sides. The envelope
member 19 is attached to the inner surface of the garment cloth C of the garment body
1.
[0050] As shown in FIG. 3, of the sheets forming the envelope member, one disposed on the
side of the garment cloth C of the garment body 1 is the first sheet 191, and one
disposed on the side of a wearer of the air-conditioned garment 100 is the second
sheet 192. In the following explanation, a surface on the inner side of the envelope
where the first sheet 191 and the second sheet 192 face with each other is an inner
surface of the envelope member 19. The surface opposite to the inner surface, i.e.,
the surface on the outer side the envelope, is an outer surface of the envelope member
19.
[0051] The first sheet 191 and the second sheet 192 may be formed by piling two separate
sheets and joining sheet edges by sewing or the like on two opposite sides. Alternatively,
the first sheet 191 and the second sheet 192 may be formed by folding a single sheet
and joining sheet edges by sewing or the like on the side opposite to the folded side.
[0052] One opening of the envelope member 19 is attached to the inner surface of the garment
cloth C of the garment body 1 around the front opening 18 by sewing or the like. A
wearer inserts a hand through the front opening 18 and the envelope member 19 into
space between the garment body 1 and the wearer's body.
[0053] Specifically, the first sheet 191 and the second sheet 192 are respectively attached
to the left and right edges of the slit as the front opening 18. Thus, the envelope
member 19 is attached to the inner surface of the garment cloth C around the front
opening 18.
[0054] As shown in FIG. 3, one of the two joined edges of the first sheet 191 and the second
sheet 192 of the envelope member 19 (in FIG. 3, the upper edge of the envelope member
19) is attached to the inner surface of the garment cloth C of the garment body 1
by sewing or the like. In contrast, the other of the two joined edges of the first
sheet 191 and the second sheet 192 (in FIG. 3, the lower edge of the envelope member
19) is not attached to the garment cloth C of the garment body 1. Thus, the lower
portion of the envelope member 19 is separated from the garment cloth C of the garment
body 1. In the example, the envelope member 19 has a shape of an envelope having an
opening on each of two sides. Alternatively, the envelope member 19 may have a shape
of a bag having an opening on only one side.
x) Absorber
[0055] The absorber 20 is a more absorbent sheet than the garment cloth C of the garment
body 1. For example, it is pile fabric and is made of a mix of rayon and polyester,
100% cotton, a mix of cotton, polyester and polyurethane, or the like. As shown in
FIG. 3, the absorber 20 covers the entire inner surface of the envelope member 19
and is disposed around the opening 18 on the inner side of the garment body 1.
[0056] To provide the absorber 20 to the garment body 1, the first sheet 191 and the second
sheet 192 forming the envelope member 19 may be more absorbent than the garment cloth
C of the garment body 1. Alternatively, the first sheet 191 and the second sheet 192
of the same fabric as the garment cloth C of the garment body 1 may be used to form
the envelope member 19. In this case, the absorber 20 is put on the inner surface
of the envelope member 19.
[0057] In the former case, the first sheet 191 and the second sheet 192 of the envelope
member 19 and the absorber 20 are the same. In this case, the absorber 20 is provided
to the outer surface in addition to the inner surface of the envelope member 19. In
the latter case, the first sheet 191 and the second sheet 192 of the envelope member
19 and the absorber 20 are separate. In this case, the absorber 20 is provided only
to the inner surface of the envelope member 19.
[0058] The absorber 20 may be removable and attachable from/to the garment body 1. In this
case, the absorber 20 can be replaced when it is stained.
II) Fan
[0059] As shown in FIG. 2 and FIG. 3, the fan 2 is inserted into the fan hole 13 to be attached
to the garment body 1. The fan 2 introduces air through the fan hole 13 into space
between the garment body 1 and a wearer's body. The power source 3 provides necessary
power to the fan 2 through the connection cable 4.
[0060] The fan 2 may have any specific configuration as long as the fan 2 can be inserted
into the fan hole 13 to be attached to the garment body 1 and can introduce air into
space between the garment body 1 and a wearer's body,.
III) Power Source
[0061] The power source 3 is a member that supplies power to the fan 2. The power source
3 has, for example, a built-in lithium-ion batteries with a safety protection circuit.
As shown in FIG. 1 and FIG. 3, the power source 3 is connected to the fan 2 through
the connection cable 4. The power source 3 includes a switch (not shown) that turns
on and off power supplied to the fan 2.
[0062] The power source 3 may have any specific configuration as long as the power source
3 can supply power to the fan 2.
IV) Connection Cable
[0063] As shown in FIG. 1 and FIG. 3, the connection cable 4 connects the power source 3
and the fan 2. The power source 3 supplies the fan 2 with power required to operate
the fan 2 through the connection cable 4.
[0064] The connection cable 4 may have any specific configuration as long as the power source
3 can supply the fan 2 with power required to operate the fan 2.
2) Effect of Embodiment
[0065] The air-conditioned garment 100 according to the embodiment includes the absorber
20 which is more absorbent than the garment cloth C of the garment body 1 around the
front opening 18 on the inner side of the garment body 1. When a wearer of the air-conditioned
garment 100 inserts a hand from the front opening 18 to the inner side of the garment
body 1, the absorber 20 wipes sweat on the hand.
[0066] The garment cloth C of the garment body 1 does not have to be the absorber 20. Any
material can be used for the garment cloth C. Therefore, the absorber 20 does not
prevent improvement in a function of cooling a wearer's body.
[0067] The absorber 20 is provided on the inner side of the garment body 1. When a wearer
wears the garment body 1, the absorber 20 is not visible from the outside of the garment
body 1. Therefore, the absorber 20 does not spoil appearance of the garment body 1.
[0068] The absorber 20 is provided to the envelope member 19 attached to the inner surface
of the garment cloth C around the front opening 18. Therefore, when a wearer inserts
a hand from the front opening 18 to the inner side of the garment body 1, the hand
is easily wiped.
[0069] Of the two joined edges of the first sheet 191 and the second sheet 192 of the envelope
member 19, the upper edge is attached to the inner surface of the garment cloth C
of the garment body 1, and the lower edge is not attached to the inner surface of
the garment cloth C of the garment body 1. Therefore, the bottom of the envelope member
19 is separated from the garment cloth C of the garment body 1. A wearer can more
easily wipe a hand with the absorber 20. Since the upper edge is attached to the garment
cloth C of the garment body 1, the envelope member 19 is prevented from being bent
while the air-conditioned garment 100 is put on.
[0070] The fan 2 of the air-conditioned garment 100 takes air into space between the garment
body 1 and a wearer's body and send air to air outlets (the hood opening 141 and the
sleeve openings 15). It cools the wearer's body much more effectively as compared
with a case in which a garment is improved only in ventilation.
[0071] The envelope member 19 extends from the front opening 18 into space between the garment
body 1 and a wearer's body. The wearer of the air-conditioned garment 100 inserts
a hand from the outside of the garment body 1 into the space between the garment body
1 and the wearer's body through the front opening 18 and the envelope member 19. Air
introduced by the fan 2 into the space between the garment body 1 and the wearer's
body cools the hand of the wearer, too.
SECOND EMBODIMENT
[0072] The second embodiment of the present invention is described based on Fig.4. Explanation
is omitted for the same parts as the first embodiment.
1) Configuration of Embodiment
[0073] As shown in FIG. 4, the garment body 1A of the air-conditioned garment 100A according
to the second embodiment has long sleeves, and includes the absorbers 20A on the inner
side of the garment body 1 around the sleeve openings 15 formed at sleeve ends. The
air-conditioned garment 100A differs from the garment body 1 of the air-conditioned
garment 100 according to the first embodiment in that the front opening 18, the envelope
members 19, and the absorbers 20 are not provided in the front. Other configurations
are the same as the air-conditioned garment 100 according to the first embodiment.
[0074] As shown in FIG. 4, the sleeves of the garment body 1A are longer than long sleeves
of a common jacket so as to cover substantially the entire hands of a wearer.
[0075] The absorbers 20A are put on the inner surface of the garment cloth C around the
sleeve openings 15. Like the absorbers 20 according to the first embodiment, the absorber
20A is a more absorbent sheet than the garment cloth C of the garment body 1A. For
example, it is pile fabric and is made of a mix of rayon and polyester, 100% cotton,
a mix of cotton, polyester and polyurethane, or the like.
[0076] In the case shown in FIG. 4, the air-conditioned garment 100A differs from the garment
body 1 of the air-conditioned garment 100 according to the first embodiment in that
the front opening 18, the envelope members 19, and the absorbers 20 are not provided
in the front.
However, in addition to the absorbers 20A provided in the long sleeves, the air-conditioned
garment 100A may be provided with the front opening 18, the envelope members 19, and
the absorbers 20 in the front.
2) Effect of Embodiment
[0077] The air-conditioned garment 100A according to the present embodiment is provided
with the absorbers 20A which are more absorbent than the garment cloth C of the garment
body 1A around the sleeve openings 15. Therefore, a wearer of the air-conditioned
garment 100A can wipe hand sweat with the absorber 20A.
[0078] The garment cloth C of the garment body 1A itself does not have to be the absorber
20A. Any material can be used for the garment cloth C. Therefore, the absorber 20A
does not prevent improvement in a function of cooling a wearer's body.
[0079] The absorber 20A is provided on the inner side of the garment body 1A. When a wearer
wears the garment body 1A, the absorber 20A is not visible from the outside of the
garment body 1A. Therefore, the absorber 20A does not spoil appearance of the garment
body 1A.
[0080] The fan 2 of the air-conditioned garment 100A takes air into space between the garment
body 1A and a wearer's body and send air to air outlets (the hood opening 141 and
the sleeve openings 15). It cools the wearer's body much more effectively as compared
with a case in which a garment is improved only in ventilation.
[0081] The sleeves of the garment body 1A are longer than long sleeves of a common jacket
so as to cover substantially the entire hands of a wearer. Air introduced by the fan
2 into the space between the garment body 1A and the wearer's body flows around the
hands. The hands of the wearer are thus cooled down.
[0082] To apply the present invention to an air-conditioned garment, the absorber may be
omitted in a case in which cooling hands is required but wiping hand sweat is not
required.
[0083] Although embodiments of the present invention have been described and illustrated
in detail, the disclosed embodiments are made for purposes of illustration and example
only and not limitation. The scope of the present invention should be interpreted
by terms of the appended claims.
