SUMMARY OF THE INVENTION
PROBLEMS TO BE SOLVED BY THE INVENTION
[0005]
However, a protective garment as in Patent Document 1 has
the problem that when a slider of a zipper is held, and the zipper
is moved downward during undressing, the slider portion cannot
be held, and thus much time is taken for undressing, so that
the garment cannot be quickly taken off in case of emergency.
[0006]

CA 03016396 2018-08-31
In addition, when a slider has a lock as in Patent Document
2, there is the problem that since the slider is touched with
an unclean hand, contaminants likely stick to a body.
[0007]
In addition, when with a grip attached inside, a zipper
is opened to put on or take off a garment as in Patent Document
3, there is the problem that since it is necessary to touch the
inside of the opening portion, contaminants stuck on a hand
likely get to the inside of the garment.
[0008]
Thus, for solving the above-described problems of prior
art, an object of the present invention is to provide a garment
which can be quickly taken off while contaminants stuck on a
hand of a wearer are inhibited from getting to the inside of
the garment and a body during undressing.

EMBODIMENT OF THE INVENTION
[0017]
A garment of the present invention is a garment having
an opening and closing portion for putting on and taking off
, .
CA 03016396 2018-08-31
the garment on the front body, in which a tab is placed at any
position on each of the left and the right outside the opening
and closing portion.
[0018]
In a preferred aspect, the garment of the present
invention has an opening and closing portion for putting on and
taking off the garment, the opening and closing portion passing
through the center of a front body to reach any position on a
waist portion.
[0019]
The garment mentioned in the present invention refers to
an over all type garment in which an upper garment and a lower
garment are integrally formed, or a garment having an opening
and closing portion on the front face of the garment, such as
a jacket or a raincoat. Specific examples of the garment
include antifouling protective garments and chemically
protecting protective garments.
[0020]
The fabric used for the garment may be any fabric such
as a woven fabric, a knitted fabric or a non woven fabric, and
synthetic fibers such as those of polyester and polyethylene
are preferably used as a fiber material that forms such a fabric.
[0021]
In addition, in the present invention, the upper end of
the opening and closing portion refers to an upper end portion
6
,
s
CA 03016396 2018-08-31
of a first tab attached to the upper end of the opening and
closing portion.
[0022]
Next, an embodiment of the garment of the present
invention will be described in detail with reference to the
drawings.
[0023]
Fig. 1 is a front view showing one aspect of the garment
of the present invention. Fig. 2 is a perspective view showing
the opening and closing portion in the present invention. Fig.
3 is a perspective view showing the upper end of the opening
and closing portion in the present invention. Fig. 4 is a front
view showing another aspect of the garment of the present
invention.
[0024]
One aspect of the garment of the present invention is a
garment of a type in which an upper garment 1 and a lower garment
2 are integrally formed as shown in Fig. 1. The upper garment
1 has hood portion 3, and as shown in Fig. 2, a first tab (large)
8a and a first tab (small) 8b, and a second tab (large) 9a and
a second tab (small) 9b are sewn to an opening and closing portion
on the left and right . In addition, in Fig. 1, a substantially
circular opening portion 30 for securing a field of view is
formed on the front face of the hood portion 3. The lower
garment 2 includes left and right leg portions 21a and 21b.
7
CA 03016396 2018-08-31
[0025]
In a preferred aspect, the opening and closing portion
for putting on and taking off the garment of the present
invention extends from the position of the upper end at the
center of the front body to the vicinity of the waist. In a
preferred aspect, the opening and closing portion 5 of a front
body 4 has the first tab (large) 8a and the first tab (small)
8b, and the second tab (large) 9a and the second tab (small)
9b on the left and right for making it possible to take off the
garment, the first tab (large) 8a and the first tab (small) 8b
are sewn on the left and right in conformity to the upper end
11 of the opening and closing portion, and the second tab (large)
9a and the second tab (small) 9b is sewn to the opening and
closing portion 5 in a lower part as compared to the first tab
(large) 8a and the first tab (small) 8b. By placing the tabs
on the left and the right of the opening and closing portion
5, and drawing the tabs to the left and right in the order of
the first tab and the second tab, the opening and closing portion
5 can be opened without holding a slider 7 of a zipper, and the
garment can be quickly taken off while contaminants are
inhibited from getting to a body because the slider is not
touched with an unclean hand.
[0026]
In a preferred aspect, the garment of the present
invention is a garment having an opening and closing portion
8
CA 03016396 2018-08-31
for putting on and taking off the garment on the front body,
in which the tab is placed at any position on each of the left
and the right outside the opening and closing portion 5.
[0027]
In a preferred aspect of the zipper in the present
invention, a distance ha from the upper end 11 of the opening
and closing portion to a zipper insertion is at least 1 cm. Here,
as shown in Fig. 3, an angle a of a line connecting the upper
end 11 of the opening and closing portion and an upper end 7a
of the slider is less than 45 at the position of the upper end
7a of the slider, and thus a force d for moving the slider 7
downward is greater than a force c for opening the tab to the
left and the right, so that a zipper 6 is easily opened. More
preferably, the zipper is attached at such a position that the
distance ha to the zipper insertion fastener is 1 cm or more
and 3 cm or less.
[0028]
When the distance ha to zipper insertion is less than
1 cm, the angle a is 45 or more, and thus the force c for opening
the tab to the left and the right is greater than the force d
for moving the slider downward, so that when there is no
difference in force c for opening the tab, the force d for moving
the slider 7 downward is reduced, thus making it difficult to
open the zipper. In addition, when the zipper 6 is placed at
such a position that the distance ha is more than 3 cm, the
9
CA 03016396 2018-08-31
upper end 11 of the opening and closing portion is opened, and
therefore contaminants may enter from the opening and closing
portion 5, resulting in sticking of contaminants to a body.
[0029]
The zipper 6 in the present invention is preferably a
fastener, and the slider 7 of the fastener is preferably a slider
having no lock. In the case of a slider having a lock, it is
necessary that the slider 7 be held by hand, lifted upward and
moved downward, so that contaminants stuck on a hand more likely
stick to a body.
[0030]
The position at which the second tab (large) 9a and the
second tab (small) 9b in the present invention are attached is
preferably at a distance of 20 cm or more and 40 cm or less from
the first tab (large) 8a and the first tab (small) 8b. In a
preferred aspect, the distance is more preferably 25 cm or more
and 35 cm or less. When the position of the second tabs 9a and
9b are at a distance of less than 20 cm, the distance from the
second tab to the waist portion is long, so that even when the
second tab is expanded to the left and the right, the opening
and closing portion 5 cannot be fully opened. In addition, when
the positions of the second tab (large) 9a and the second tab
(small) 9b are disposed at a distance of more than 40 cm below
the first tab (large) 8a and the first tab (small) 8b, the zipper
can be opened to the vicinity of the solar pleus, but the second
=
CA 03016396 2018-08-31
tab is disposed below the solar pleus, and therefore even when
the second tab (large) 9a and the second tab (small) 9b are
expanded to the left and the right, the opening and closing
portion 5 cannot be opened.
[0031]
In the present invention, it is preferable that the first
tab (large) 8a and the first tab (small) 8b have
bilateral-asymmetric in size, and the second tab (large) 9a and
the second tab (small) 9b have bilateral-asymmetric in size.
More preferably, the smaller tabs, e.g. the first tab (small)
8b and the second tab (small) 9b, are disposed inside the larger
tabs, e.g. the first tab (large) 8a and the second tab (large)
9a.
[0032]
Generally, when a tab is placed, a double-sided tape or
a fastener tape are often placed inside the tab for suppressing
fluttering of the tab. Here, when the sizes of tabs on left
and the right are the same, or the size of a tab disposed on
the lower side is larger than the size of the other tab, the
upper and lower tabs are bonded to each other at the time of
providing a double-sided tape or a fastener tape inside the tab
disposed on the upper side.
[0033]
It is preferable to provide a cover member 10 which covers
the opening and closing portion 5 at the time of closing the
11
CA 03016396 2018-08-31
opening and closing portion 5, and exposes the opening and
closing portion 5 at the time of opening the opening and closing
portion 5. The cover member 10 is formed of a fabric identical
to that of a body part, and the cover member 10 can be kept in
a closed state by a double-sided tape, a fastener tape or the
like.
[0034]
The garment of the present invention is produced in the
following manner. The fabric that forms the garment is cut into
parts such as the upper garment 1, the hood portion 3, the leg
portions 21a and 21b, the first tab (large) 8a, the first tab
(small) 8b, the second tab (large) 9a, and the second tab (small)
9b.
[0035]
Examples of the method for joining the parts include
sewing with a sewing thread, welding with an ultrasonic wave
or a high-frequency sewing machine, and bonding with an adhesive
tape. In addition, the jointed portion can be reinforced with
a resin tape or the like. In addition, the first tab (large)
8a and the first tab (small) 8b, the second tab (large) 9a and
the second tab (small) 9b, and fasteners are attached to the
opening and closing portion 5 on the left and the right, and
the cover member 10 is attached to the opening and closing
portion 5 on one of the right or the left so as to cover the
opening and closing portion 5. In addition, a stretchable
12
CA 03016396 2018-08-31
material such as rubber is sewn to a hood hem opening 30, a sleeve
hem, a bottom hem, and the like.
[0036]
The garment of the present invention is put on and taken
off in the following manner. For putting on the garment, the
body is put in the garment from the opening and closing portion
5, and fitted with the garment, and the hood portion 3 is put
on the body. Subsequently, the slider 7 of the fastener is moved
to the position of the upper end of the zipper, and the opening
and closing portion 5 is closed. Thereafter, the first tab
(large) 8a and the first tab (small) 8b, the second tab (large)
9a and the second tab (small) 9b, and the cover member 10 are
closed to cover the opening and closing portion 5.
[0037]
Also, for taking off the garment, the cover member 10,
the first tab (large) 8a and the second tab (large) 9a are opened
to expose the opening and closing portion 5. Subsequently, the
tabs are opened in the left and right in the order of the first
tab (large) 8a and the first tab (small) 8b, and the second tab
(large) 9a and the second tab (small) 9b, so that the opening
and closing portion 5 is opened. Next, the head is released
from the hood portion 3, and both the sleeves are unfastened.
The garment is drawn down, and finally both the legs are drawn
out to take off the garment.

[0050]
(Comparative Example 1)
As with Example 1, a vertically continuous over all type
18
CA 03016396 2018-08-31
garment was fabricated using as a fabric a non woven fabric
obtained by providing a non woven fabric on each of the front
and back sides, and disposing a waterproof and
moisture-permeable film between the non woven fabrics on the
front and back sides. For joining at each position, welding
was performed with a seam margin of 1 cm using an ultrasonic
welding machine, and welded portions were bonded with a resin
tape. Here, only one tab (large) was sewn to an upper end of
an opening portion 5 on the left side of the opening and closing
portion 5, a slider having a lock was used as the slider 7 to
be attached to a zipper 6, and a distance ha to a zipper
insertion was 0 cm. A cover member 10 was sewed so as to cover
the opening and closing portion 5 with the cover member 10. Here,
the tab was disposed on the cover member 10. In addition, rubber
was sewn to a hood hem, a sleeve hem, and a bottom hem. Results
are shown in Table 1.
