Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This is the U.S. national stage of application No.
PCT/JP2011/072275, filed on 28 Sep. 2011. Priority under 35U.S.C.
.sctn.119 (a) and 35 U.S.C. .sctn.365 (b) is claimed from Japanese
Application Nos. 2010-221306.2, filed 30 Sep. 2010, and
2011-093084, filed 19 Apr. 2011, the disclosures of which are also
incorporated herein by reference.
TECHNICAL FIELD
[0002] The present invention relates to trousers, work trousers,
and overalls, and particularly relates to ones which are partially
formed of a stretchable material.
BACKGROUND ART
[0003] Conventionally, there have been known sportswear and
dancewear partially provided with a stretchable material to
demonstrate fastening force for facilitating exercises (see, for
example, PTL 1, PTL 2).
[0004] Sportswear disclosed in PTL 1 is lower wear designed to
improve movability in adduction or abduction exercise and provided
with a stretchable material for fastening the body of a wearer, the
stretchable material arranged spirally from the back side of the
lumbar to the crotch through the lateral sides of the lower
wear.
[0005] Also, dancewear disclosed in PTL 2 is formed by joining
multiple different materials and a cloth having fastening force is
provided in predetermined positions of the wear. This prevents
fatigue and facilitates keeping of body balance.
[0006] In other words, the conventional sportswear and dancewear
are designed to fasten the body of a wearer with a stretchable
material (stretchable members) to a moderate degree that enables
balance keeping and prevention of fatigue during exercises by
applying a load to muscles, and thereby to demonstrate effects in
heavy exercises such as running and dancing.

SUMMARY OF INVENTION
Technical Problem
[0009] In this connection, workers working on a roof or the like
for installing solar panels or doing the like often make movements
of keeping a squat-down position for a long period of time, moving
from a standing position to a squat-down position when lifting and
carrying a load, and walking on the roof after shifting from the
squat-down position to the standing position.
[0010] More specifically, since a worker may fall from the roof by
losing the balance, the worker keeps the posture low (squat-down)
to prevent the falling. Also, since installation sites of the solar
panels are around the worker's foot side, the worker needs to be
kept squatted down and work for a long time. Furthermore, there are
cases where the worker frequently repeats movements from the
squat-down position to the standing position and vice versa in
order to carry solar cell panels or change work positions on the
roof.
[0011] When the squat-down position or the squat-down movement is
kept for a long period of time, the conventional sportswear or
dancewear fastening one portion of the body of a wearer causes a
problem of excessively fastening the one portion of the body of the
wearer and fails to provide a sense of comfort.
[0012] In addition to the problem of comfort, if a wearer wearing
conventional sportswear or dancewear keeps the squat-down position
for a long period of time, there is a possibility that the wearer
may lose balance when standing up because compression of blood
vessels of the legs may make the legs numb. Also, if the trousers
(the conventional sportswear or dancewear) are tight and hinders
the squat-down position, the wearer cannot smoothly take the
squat-down position. Thus, there is a possibility that the wearer
may lose the balance when moving to the squat-down position.
[0013] Accordingly, there is a high risk of accidents of falling
from the roof. That it, in works for low-rise houses, very many
accidents of falling are occurring. In 2009, totally 114,152 death
and injury accidents (death cases and injury cases with four or
more days off) of falling happened in all industries in Japan.
Among the accidents, 20,006 accidents, which are 17.5% of the
total, were caused by falling (according to the states of death and
injury accidents by cause and by industry type, "A workers' death
and injury report" by Health, Labour and Welfare Ministry: Japan
Advanced Information Center of Safety and Health). The death
accidents due to falling dominate a high percentage in the
engineering work related to low-rise houses in spite of its
business scale. In the construction industry, 39.62% of the death
accidents were caused by falling, and 17.00% of the falling was
caused in the construction works (for low-rise houses) (according
to the homepage of Construction Industry Safety and Health
Association).
[0014] With the increase of solar power generation which draws
attention as clean energy, for example, the number of works on the
roof of the low-rise houses tends to increase. Also, with recent
popularity of designed houses, the variety of low-rise houses has
become wider, which makes it difficult to take security measures.
Accordingly, to prevent falling accidents in the low-rise houses
has become more important.
[0015] Also, for example, many accidents that occurred during roof
works are reported in "Major Industrial Accidents in Aichi
Association for Constructional Industry 2002." Workers underwent
serious injury or death accidents by losing the balance or taking
difficult positions on a roof or a ladder. Thus, the sense of
comfort provided to the workers (wearers) in work sites can prevent
accidents from occurring as much as possible.
[0016] An object of the present invention is to provide trousers,
work trousers, and overalls which can provide a sense of comfort
(do not harm comfort) in any position, such as a squat-down
position, a knee-raised position, a tiptoe squat position, and a
leg-crossed sit position.

DESCRIPTION OF EMBODIMENTS
[0047] Trousers 1 are long pants (work trousers) which are used for
works with the configuration in which a skin of a wearer does not
come in tight contact therewith during being worn, in other words,
in a state where small space is present between the skin of the
wearer and the trousers 1. Note that when the wearer wearing the
trousers 1 is in a standing position, the state of the trousers 1
is as shown in FIGS. 1 to 3.
[0048] The trousers 1 includes a predetermined portion formed of a
stretchable material (an inner side stretchable material; an outer
side stretchable material) 3. The stretchable material is a two-way
stretch type which is formed of knit (knitted). In other words, the
stretchable material 3 has a stretching property in an in-plane
direction (any direction perpendicular to a direction of a
thickness of the stretchable material 3). Note that the stretchable
material 3 is not provided with a purpose of tightening the body of
the wearer of the trousers 1.
[0049] As the stretchable material 3, a stretchable material with a
stretch rate (an extending rate) of approximately 170% is employed
but one with a stretch rate of approximately 160% to 190% may be
employed, or one with a stretch rate of approximately 140% to 220%
may be employed. Furthermore, one with a stretch rate of
approximately 120% to 250% may be employed. In addition, as the
stretchable material 3, one with a stretch rate of approximately
120% to 170% may be employed or one with a stretch rate of
approximately 110% to 130% may be employed.
[0050] Note that the stretch rate is expressed by the following
equation. (Stretch rate=a maximum length of the stretchable
material 3 when force is applied/a length of the stretchable
material 3 when force is not applied.times.100%)
[0051] Here, the maximum length of the stretchable material 3 when
force is applied means a length of the stretchable material 3 when
maximum tensile force is applied to the stretchable material 3. If
the tensile force to be applied to the stretchable material 3
gradually increases from "0," the length of the stretchable
material 3 is also gradually increased. However, when the
stretchable material 3 is pulled with force equal to or larger than
the maximum tensile force, the stretchable material 3 hardly
extends and is rather broken. Also, as long as the stretchable
material 3 is pulled with force equal to or smaller than the
maximum tensile force, it is designed that the stretchable material
3 is restored. However, when the stretchable material 3 is pulled
with force larger than the maximum tensile force (the maximum
tensile force in the limit of elasticity), permanent distortion
remains in the stretchable material 3.
[0052] Here, the specific description of a case when the stretch
rate is 170% is given. It is assumed that the stretchable material
3 with a predetermined thickness, a predetermined width, and a
predetermined length LA (a length of the stretchable material when
tensile force is not applied is LA; for example, 100 mm) is pulled
from the both ends thereof in the longitudinal direction with
tensile force. When the maximum tensile force is applied, the
length of the stretchable material 3 becomes 1.7 times longer
(1.7LA; for example, 170 mm).
[0053] Also, regions other than the region using the stretchable
material 3 are formed of woven fabric (fabric) with little
stretchability. The stretch rate of the woven fabric is
approximately 100% to 102%, which is smaller than the extension
rate of the stretchable material.
[0054] Note that a fabric with stretchability may be employed as
the stretchable material 3 in place of knitted fabric. It is
assumed that the fabric with stretchability is formed by being
woven with stretchable strings.
[0055] The stretchable material 3 is provided in a portion
substantially in a single-roll helical shape vertically extending
to a near-knee inner side region 15 from a lumbar region (a lower
lumbar region) 7 through an upper hip region 9, a hip joint outer
side region 11, and a front-side middle thigh region 13 in this
order. Also, the stretchable material 3 has a predetermined
width.
[0056] Here, the lumbar region 7 is a region for a part immediately
behind the lumbar (a lower part of the lumbar) of the wearer (a
region immediately behind a part between the crotch and the back
waist and immediately below the waist band portion 17; the lower
lumbar region). The upper hip region 9 is a region for the upper
part of the left or right side of the hips of the wearer. The hip
joint outer side region 11 is a region for an outer side of the hip
joint of the wearer (a region for skin parts of the wearer located
on the left of the left hip joint of the wearer, or a region for
skin parts of the wearer located on the right of the right hip
joint of the wearer).
[0057] The front-side middle thigh region 13 is a region for a part
located in a middle position in the vertical direction of the thigh
area of the wearer and on the front side of the thigh area. The
near-knee inner side region 15 is a region for a part near the knee
of the wearer and on an inner side of the thigh area (the right
side of the left thigh area of the wearer and the left side of the
right thigh area of the wearer). Note that the lumbar region 7 and
the like are regions facing the skin parts of the lumbar and the
like of the wearer wearing the trousers.
[0058] The trousers 1 is formed symmetrically and the helical
stretchable material 3 are provided symmetrically. Accordingly, on
the left side of the trousers 1, the portion from the left lumbar
region 7L to the left near-knee inner side region 15L via the left
upper hip region 9L, the left hip joint outer side region 11L, and
the left front-side middle thigh region 13L is formed of the
helical stretchable material 3L with a predetermined width (in a
helical state in a clockwise direction when the trousers 1 is seen
from the top thereof).
[0059] On the right side of the trousers 1, the portion from the
right lumbar region 7R to the right near-knee inner side region 15R
via the right upper hip region 9R, the right hip joint outer side
region 11R, and the right front-side middle thigh region 13R is
formed of the helical stretchable material 3R with a predetermined
width (in a helical state in an anticlockwise direction when the
trousers 1 is seen from the top thereof).
[0060] Note that the stretchable material 3L on the left side and
the stretchable material 3R on the right side are connected with
each other at the lumbar of the wearer (see, FIG. 3).
[0061] Hereinafter, further details are described by using the left
or right side of the trousers 1 as an example.
[0062] The near-knee inner side region 15L of the stretchable
material 3L on the left side reaches slightly behind the region of
an inseam 19 of the trousers 1.
[0063] Here, FIG. 7 is used to more specifically describe the state
where the near-knee inner side region 15L of the stretchable
material 3L on the left side reaches slightly behind the region of
the inseam 19 of the trousers 1. Note that FIG. 7 shows a
cross-sectional view of a tube portion on the left side of the
trousers 1 (a tube portion into which the left leg enters).
However, since the trousers 1 is formed symmetrically as described
above, a tube portion of the trousers 1 on the right side is also
formed similarly to the tube portion on the left.
[0064] FIG. 7 (a) is a drawing showing a cross-section taken along
the IXA-IXA line in FIG. 3 and is a cross-sectional view of the
trousers 1 in the lowermost end of the stretchable material 3L (a
lower end of a linear joint portion between the stretchable
material 3L and a left back pants cloth 27L). FIG. 7(b) is a
drawing showing a cross-section taken along the IXB-IXB in FIG. 3
and is a cross-sectional view of the trousers 1 slightly upper than
the lowermost end of the stretchable material 3L.
[0065] The reference sign LG shown in FIG. 7 shows the thigh area
of the wearer wearing the trousers 1. The reference signs PA1, PB1
show a side seam 33 of the trousers 1. The reference signs OA, OB
show the center of the thigh area LG and the center of the tube
portion of the trousers 1. The reference signs LA1, LB2 show a
straight line connecting the side seam 33 and the inseam 19 of the
trousers 1. Note that it is assumed that the center OA of the thigh
area LG shown in FIG. 7(a) is present on the straight line LA1, for
example, and the center OB of the thigh area LG shown in FIG. 7(b)
is present on the straight line LB1, for example.
[0066] In FIG. 7(a), the reference sign PA2 shows the lowermost end
of the stretchable material 3L (see FIG. 3 together) and the
reference sign LA2 shows the straight line connecting between the
center OA of the thigh area LG and the lowermost end PA1 of the
stretchable material 3L. Here, an angle.theta.A1 of intersection
between the straight line LA1 and the straight line LA2 is
approximately 15.degree..
[0067] In FIG. 7(b), the reference sign PB2 shows the portion
slightly upper than the lowermost end of the stretchable material
3L (see FIG. 3 together) and the reference sign LB2 shows the
straight line connecting between the center OB of the thigh area LG
and the portion PB2 slightly upper than the lowermost end of the
stretchable material 3L. Here, an angle .theta.B1 of intersection
between the straight line LB1 and the straight line LB2 is
approximately 15.degree.. Note that the reference sign PB3 is a
boundary between the stretchable material 3L and the left anterior
trousers cloth 25L.
[0068] As above, the near-knee inner side region 15L of the
stretchable material 3L reaches slightly behind the region of the
inseam 19 of the trousers 1. Note that the intersection angle
.theta.A1 or the intersection angle .theta.B1 may be set as needed
in a range from 10.degree. to 20.degree., which is wider than
15.degree., or may be set in a range which is further wider than
5.degree. to 30.degree., or may be set as needed in a range which
is further wider than 5.degree. to 60.degree..
[0069] The width of the stretchable material 3R (3L) on the right
becomes downwardly wider gradually. Here, the width direction of
the stretchable material 3R (3L) is a direction perpendicular to a
helical extending direction (the longitudinal direction) of the
stretchable material 3R (3L). However, the width direction of the
stretchable material 3R (3L) may be set in the vertical direction
of the trousers 1.
[0070] FIG. 4 shows shapes of the stretchable material 3R and the
like on the right side before being sewed together. The stretchable
material 3R and the like shown in FIG. 4 are formed in a planar
shape. Also, a direction perpendicular to the paper plane of FIG. 4
is a thick direction of the stretchable material 3R and the like.
Note that seam allowances of the stretchable material 3R and the
like are not illustrated in FIG. 4 for sake of simplicity.
[0071] The trousers 1 is formed by, for example, sewing together
the stretchable material 3R, a right front body cloth 21R (in the
case of a left front body cloth, 21L), a right back side joint
cloth 23R (in the case of a left back side joint cloth, 23L), a
right front pants cloth 25R (in the case of a light front pants
cloth, 25L), and a right back pants cloth 27R (in the case of a
left back pants cloth, 27L) as needed.
[0072] Here, it is designed that one side portion 29R of the right
front pants cloth 25R and one side portion 31R of the right back
pants cloth 27R are jointed with each other to form the side seam
33 of the trousers 1.
[0073] Also, one portions of another side portion (one side portion
facing the one side portion 29R) of the right front pants cloth 25R
and another one side portion (one side portion facing the one side
portion 31R) 37R of the right back pants cloth 27R are joined
together to form a joint portion (a sewing portion) 39 near the
inseam 19 (see, FIG. 3). Note that the two-dot chain line L1 shown
in the right front pants cloth 25R is a portion to be the inseam 19
of the trousers 1.
[0074] Also, other portions of another side portion (one end
portion in the longitudinal direction) 52R of the stretchable
material 3 and one portion of another side portion 37R of the right
back pants cloth 27R are joined together to form the joint portion
39 near the inseam 19.
[0075] Accordingly, the near-knee inner side region 15R of the
stretchable material 3L reaches a portion slightly behind the
region of the inseam 19 of the trousers 1.
[0076] In addition, it is designed in the trousers 1 that another
one side portion 41R of the right front pants cloth 25R and another
one side portion 43R of the right back pants cloth 27R are joined
together with the one side portion (one side portion in the width
direction) of the stretchable material 3, and one side portion 47R
of the right front open cloth 21R and one side portion 49R of the
right back side joint cloth 23R are joined together with one side
portion (the other side portion in the width direction) 51R of the
stretchable material 3. Note that the both side portions 45R, 51R,
(45L, 51L) in the width direction of the stretchable material 3 is
substantially straight for facilitating the joint.
[0077] Although portions other than the joints are also joined in
the trousers 1, the description thereof is omitted.
[0078] As described above, in the trousers 1 that is formed by
joining together the stretchable material 3, the right front open
cloth 21R, the right back side joint cloth 23R, the right front
pants cloth 25R, and the right back pants cloth 27R, compression
force is, of course, not applied to the stretchable material 3 and
tensile force is also not applied. In other words, no force is
applied.
[0079] Also, in the trousers 1, the ring-shaped waist band portion
17 is joined by sewing or the like with the upper portion of the
front open cloths 21R, 21L and the back side joint cloths 23R, 23L,
and side pockets 55 and back pockets 57 are provided.
[0080] Furthermore, in the trousers 1, when seen from the front
side thereof, a crotch seam 6 and the stretchable material 3 have a
predetermined distance between them (a distance in the inseam 19)
L2 (for example, approximately 100 mm) (see, FIG. 1). Accordingly,
the strength of the trousers 1 (tensile strength in the crotch seam
6 and the like) can be increased, and also the looking of the
trousers 1 can be improved when seen from the front thereof. In
other words, if the distance L2 is set "0," the stretchable
material 3L and the stretchable material 3R are joined together in
the crotch seam 6 of the trousers 1, which results in decreasing
the strength in the crotch seam 6. In addition, when the wearer of
the trousers 1 is seen from the front thereof, the wearer looks as
if he/she put underwear on the trousers. Thus, the looking is
bad.
[0081] However, the crotch seam 6 and the stretchable material 3
are spaced apart from each other by the predetermined distance L2,
so that the strength insufficiency and bad looking can be
avoided.
[0082] In addition, in the trousers 1, as shown in FIG. 1, in the
vertical direction, a value of the distance (dimension) L2, a value
of the distance (dimension) L3, and a value of the distance
(dimension) L4 are substantially equal to one another, or the value
of the distance L4 is slightly larger than the value of the
distance L3, and the value of the distance L3 is slightly larger
than the value of the distance L2.
[0083] Accordingly, even in a case where the wearer of the trousers
1 takes a squat-down position with the skin of the legs extended,
the trousers 1 stretches as needed and thus the wearer does not
feel any sense of discomfort. In other words, in the squat-down
position, the skin on the thigh area of the wearer is extended
utmost at the knee portions. The extended amount of the trousers 1
becomes gradually smaller from the knee portion toward the crotch
portion. The dimensions L2, L3, and L4 are set as described above,
so that the stretchable material 3 is provided near the portions in
which the skin stretches. Accordingly, the stretchable material 3
stretches following the stretch of the skin. Thus, there is almost
no sense of discomfort. Note that, even when the dimension L4 is
set smaller than the dimension L2 or the dimension L3, the
stretchable material 3 follows the stretch of the skin on the front
side of the thigh portion. On the other hand, however, the
stretchable material 3 is placed in a friction portion (near-knee
portion), which is not preferable. Also, if the dimension L2 is set
"0" or smaller, the stretching region of the skin on the thigh
front side and the position of the stretchable material 3 do not
meet each other. Thus, the wearer may feel a sense of
discomfort.
[0084] Note that the dimension L3 is a dimension in the vertical
direction of the stretchable material 3 (the width of the
stretchable material 3 in the inseam 19) and the dimension L4 is a
dimension between a region for the center of the knee and the lower
end of the stretchable material 3 (the dimension of the right front
pants cloth 25R or the left front pants cloth 25L in the inseam
19).
[0085] The trousers 1 provides an effect of making a wearer feel
comfortable (without losing a sense of comfort) in any position,
such as the squat-down position, knee-raised position, tiptoe squat
position, open legs position or the like when the wearer wears the
trousers 1. In other words, even though a wearer (a worker) works
on the roof or the like in a position such as the squat down
position or open leg position, the trousers 1 ensure the comfort of
the wearer following the position of the wearer.
[0086] More specifically, among joints of a human body, main joints
related to the trousers 1 are hip joints and knee joints. For
example, the shape of the trousers 1 is decided along with a state
(a standing state; a stand-upright state) where the wearer does not
bend the hip joints and the knee joints.
[0087] Here, for example, as shown in FIG. 5, in contrast with the
standing state, when the wearer is in the knee-raised position, the
legs of the wearer is most deformed and the deformation force is
most received by the wearing trousers 1 of the wearer from the legs
of the wearer. In other words, the hip joint is bent and the knee
joint is bent so that the crotch portion opens, and the other knee
(the right knee in FIG. 5) kneels on the ground or the floor.
Accordingly, in the knee-raised position, the tensile force as
shown by an arrow in FIG. 5 acts on the trousers 1. Even when such
tensile force acts, the stretchable material 3 stretches as needed.
Thus, the wearer wearing the trousers 1 easily takes the
knee-raised position.
[0088] When the wearer is in the knee-raised position as shown in
FIG. 5, the stretchable material 3 stretches most in the width
direction of the stretchable material 3 in the portion shown by the
arrow (the near-knee inner side region). Also, it is designed that
the stretchable material 3 stretches in other portions. Then, the
stretchable material 3 is formed in one helical state, so that the
stretchable material 3 extends substantially 360.degree. around the
axis of the leg as the center thereof. Thus, when the wearer is in
the knee-raised position as shown in FIG. 5, the stretchable
material 3 elastically deforms as needed, which makes the wearer to
easily take the knee-raised position.
[0089] The case where the wearer is in the knee-raised position as
shown in FIG. 5 is further specifically described by using FIG. 6.
FIG. 6(a) is a drawing showing a state where the wearer is in the
standing position (the stand upright position). FIG. 6(b) is a
drawing showing the wearer is in the knee-raise position, which
corresponds to FIG. 5.
[0090] A curve L11 shown by the broken line in FIG. 6(a) extends
from the inner part of the right knee of the wearer to the inner
part of the left knee of the wearer via the crotch of the wearer
(passes through the inner thigh of the wearer). Also, a curve L12
shown by the broken line in FIG. 6(b) is a curve passing through
the same portions as the curve L11 (parts of the skin of the same
wearer as the wearer shown in FIG. 6 (a)).
[0091] In the state shown in FIG. 6 (a), the curve L11 has a length
of 70.5 cm, for example, whereas in the state shown in FIG. 6 (b),
the curve L12 has a length of 83.5 cm, for example. Accordingly,
the length of the skin in the inner thigh area of the wearer
increases by approximately 18%.
[0092] In this manner, even when the length of the skin in the
inner thigh area of the wearer increases by approximately 18%,
since the stretchable material 3 is provided, the wearer can easily
take the knee-raised position.
[0093] On the other hand, since a stretchable material is not
provided in trousers including a front body 201 and a back body 203
as shown in FIG. 20, the trousers cannot sufficiently accommodate
the 18% increase. Thus, the wearer can hardly take the knee-raised
position.
[0094] Note that the trousers 1 can provide a sense of comfort not
only when the wearer is in the knee-raised position but also when
the wearer is in the tiptoe squat position, the crossed leg
position, and the like, and the wearer can easily take the tiptoe
squat position or crossed leg position as similar to the case where
the wearer is in the knee-raised position.
[0095] Also, the stretchable material 3 is weaker to friction or
stretching as compared with the other regions of the trousers 1
(the region formed of woven fabric) and the knitted string thereof
tends to cause snagging or pilling by the friction or scratching.
However, since the stretchable material 3 is provided in the
above-described portion in the trousers 1, even when the wearer
sits down on the floor or the ground with the trousers 1 being put
on during working, the stretchable material 3 is unlikely to come
in touch with the floor or the ground or the wall. For example, the
stretchable material 3 is positioned at an upper region of the hips
while avoiding a lower region of the hips. Thus, even when the
wearer sits down with the hips placed on the roof, the stretchable
material 3 does not come into contact with the roof. Accordingly,
the friction or the like does not occur (the snagging or the
pilling does not occur) in the stretchable material 3, so that the
stretchable material 3 is prevented from being damaged as much as
possible.
[0096] On the other hand, in case of conventional sportswear or
dancewear, an entire wear is formed of a stretchable material such
as knit. Thus, snagging or pilling is easily occurred when a wearer
is working on the roof or the like.
[0097] Also, the stretchable material 3 is provided as described
above. Accordingly, the stretchable material 3 and the side pockets
55 do not interfere with each other. Thus, the side pockets 55
become easy to place.
[0098] Furthermore, the region formed of the stretchable material 3
does not exist under the knee in the trousers 1, so that the amount
of the stretchable material 3 used is reduced and such a damage
that entanglement is caused by contact between the stretchable
material 3 and the wall or the like in the region under the knee
can be prevented.
[0099] Also, in the trousers 1, the near-knee inner side region 15
of the stretchable material 3 reaches slightly behind the region of
the inseam 19 of the trousers 1. Accordingly, the wearer becomes
easier to take the knee-raised position when wearing the trousers
1.
[0100] In other words, as described above, it is preferable that
the stretchable material 3 greatly stretch at the inseam 19 of the
trousers 1 when the wearer is in the knee-raised position. However,
if the near-knee inner side region 15 stops at the region of the
inseam 19 of the trousers 1, the stretchable material 3 joined with
the woven fabric cannot sufficiently stretch due to the
interruption of the woven fabric. In contrast, in the trousers 1,
the near-knee inner side region 15 of the stretchable material 3
reaches slightly behind the region of the inseam 19 of the trousers
1. Accordingly, the effect of the woven fabric becomes smaller and
the stretchable material 3 sufficiently stretches at the region of
the inseam 19 of the trousers 1. Thus, the wearer can further
easily take the knee-raised position.
[0101] Also, since the width of the stretchable material 3
gradually downwardly increases in the trousers 1, the wearer can
further easily take the knee-raised position.
[0102] In other words, when the wearer takes the knee-raised
position as shown in FIG. 5, the stretchable material 3 stretches
most in the width direction at the inseam 19 in the near-knee inner
side region 15. The amount of stretch becomes upwardly smaller. In
this manner, since the width of the stretchable material 3
gradually downwardly increases, the wearer can further easily take
the knee-raised position.
[0103] Also, since the width of the stretchable material 3 is
smaller on the upper side (the lumbar side), the stretchable
material 3 and the back pockets 57 do not interfere with each other
even when the back pockets 57 are provided on the hip region of the
trousers 1, the stretchable material 3. Thus, the back pockets
become easier to be placed.
[0104] Furthermore, the stretchable material 3 obliquely extends in
a direction close to the horizon on the upper side of the trousers
1 (the lumbar, particularly the sacral region and vicinity
thereof). Thus, the interference with the back pockets 57 can be
further securely avoided.
[0105] Also, since the trousers 1 is provided with the stretchable
material 3, the wearer can easily bend the knees or the waist to
open legs even when the trousers 1 stick to the skin of the legs of
the wearer with sweat. In other words, in the case of conventional
trousers, if a wearer tries to make a movement such as to open legs
with the trousers sticking to the legs of the wearer, slippage
hardly occurs between the trousers and the skin of the legs. Thus,
the trousers disturb the movement of opening the legs of the
wearer. However, in the case of the trousers 1, if the wearer tries
to make a movement such as to open legs with the trousers 1
sticking to the legs of the wearer, slippage hardly occurs between
the trousers 1 and the skin of the legs, but the stretchable
material 3 stretches as needed, so that the trousers do not
disturbs the movement of opening the legs of the wearer.
[0106] Also, in the case of the trousers 1, even when the wearer
squats down with the knees or the like bent from the standing
state, the stretchable material 3 stretches as needed. Accordingly,
there is no need to lift up the trousers (the conventional
trousers) as shown in FIG. 16. And, even when the both hands of the
wearer are blocked with a luggage or the like, the wearer can
easily take in the squat-down position.
[0107] Here, the stretch or the like of the skin of the wearer (the
worker) of the wearer 1 is described.
[0108] When the worker takes the squat-down position such as tiptoe
squat or knee raising (takes the squat-down position from the
standing position), the change in the body dimensions occurs. This
change in the dimensions occurs due to extension and contraction of
the skin by bending and stretching of mainly the hip joint and the
knee joint, the contraction of muscle, and movement of bones. Main
positions of the squat-down position are "bending and stretching,"
"tiptoe squat," and "leg-crossed sit." The worker works on the roof
while keeping the squat-down position for a long period of
time.
[0109] In the squat-down position, the bending movement of the
joints of the legs is at least performed. In the tiptoe squat
position, the legs perform outward turn and abduction movement in
addition to the bending movement of the legs.
[0110] The bones particularly related to the squat-down position
include the pelvis, the femur, the patella, and the tibia. Portions
which connect these bones related to the squat-down position and
which are movable are joints. The joints particularly related to
the squat-down position are the hip joint which is a connected
portion of the pelvis and the femur, and the knee joint which is a
connected portion of the femur and knee cap.
[0111] The movement of the joints in the squat-down motion (the
motion changing from the standing position to the squat-down
position) is described. As for the legs, when squatting down, the
hip joint and the knee joint are bent. Also, in the squat-down
movement along with the opening-leg movement such as the tiptoe
squat, the hip joint outwardly turns and abducts.
[0112] The bending of the hip joint is a movement to bend the leg
thrusting forward. When the worker is standing (when in the
standing position), if the knees are not bent, the leg (the thigh
area) can be bent at an angle up to approximately 90.degree. to the
body (the belly part and the chest part). Also, when the worker is
standing (when in the standing position), if the knees are bent,
the leg (the thigh area) can be bent at an angle up to
approximately 125.degree. to the body (the belly part and the chest
part).
[0113] The bending in the hip joint is a movement in which the
lower leg part (a part of the leg below the shin) is bent
backwardly putting out to the thigh area and can be bent at an
angle up to approximately 130.degree..
[0114] The abduction in the hip joint is a movement in which the
thigh area is opened so that the thigh area moves apart from the
body axis. The thigh area can be bent by an angle up to
approximately 45.degree. toward the side with respect to the body
axis (the trunk of the body).
[0115] The outward turn in the hip joint is a movement in which the
thigh area is turned (rotated) about the axis of the thigh area and
the thigh area can be bent by an angle up to approximately
20.degree..
[0116] The squat-down movement of the worker is made in combination
of the bending movements of the hip joint and the knee joint, the
abduction movement of the hip joint, and the outward turn of the
hip joint.
[0117] The movement of the muscles in the squat-down motion (the
motion changing from the standing position to the squat-down
position) is described. The muscles acting in the squat-down
movement are muscles of the legs.
[0118] More specifically, when the hip joint is bent, the psoas
major muscle, the iliac muscle, the rectus femoris muscle, and the
sartorius muscle are contracted. When the hip joint is bent, the
gracilis muscle, the sartorius muscle, the biceps femoris muscle,
the semimembraneous muscle, the semitendinosus muscle, the
gastrocnemius muscle, and the popliteus muscle are contracted. When
the hip joint is abducted, the gluteus medius muscle, the gluteus
minimus muscle, and the sartorius muscle act, while when the hip
joint is outwardly turned, the gluteus maximus muscle, the
piriformis muscle, the sartorius muscle, and the biceps femoris
muscle act.
[0119] As described above, the kinds of motions, bones, joints, and
muscles in the squat-down movement are described. However, the
dimensions of the body surface changes according to the motions in
the squat-down movement. This is because the body surface U (the
skin of the worker) is extended and the position is changed by the
movement of the bones, the contraction of the muscles, and bending
of the joints in the squat-down movement.
[0120] Here, the change in the body surface is described.
[0121] Due to the bending movement, the abduction, and outward turn
movement of the hip joint and the bending movement of the knee
joint, the muscles of the thigh area (the psoas major muscle, the
iliac muscle, the rectus femoris muscle, and the sartorius muscle)
are contract. As a result, protrusion of the muscles occurs and the
circumference of the thigh area (the outer circumferential length;
the diameter of the thigh area) becomes larger. Furthermore, the
tendon protrudes on the back portion of the knee. Accordingly, the
dimension of the knee portion also becomes larger.
[0122] When the hip joint is bent, the pelvis and the femur are
moved (turned). When the knee joint is bent, movements (positional
changes) in the pelvis, the femur, the patella, and the tibia in
the knee joint occur. When the hip joint is abducted, the femur
moves in a direction away from the body axis. When the hip joint is
outwardly turned, the patella moves to the side of the body.
[0123] The skin of the hips extends due to the bending of the hip
joint. The surface of the knee portion protrudes and the skin of
the front portion of the knee extends due to the bending of the
knee joint. The skin from the crotch portion to the inner side of
the knee extends due to the abduction of the hip joint. The skin
from the front portion of the knee to the crotch portion extends
due to the outward turn of the hip joint.
[0124] The change in the above-described extension of the skin in
the knee-raised position (the change occurred when moving from the
standing position to the knee-raised). Note that, the knee-raised
position is shown in FIG. 5, FIG. 6, FIG. 9(a), FIG. 12(a), FIG.
14, and FIG. 15. In the knee-raised position, one hip joint is
opened and the other knee touches the roof. In FIG. 9, FIG. 12,
FIG. 14, and FIG. 15, the worker bends the left knee on the
roof.
[0125] FIG. 8 (a) is a drawing in which the thigh areas and the
belly are seen from the front side when the wearer is standing.
Also, FIG. 8(a) shows A to D and A' to D' of skin parts (the parts
on the front and inner sides in the thigh areas including the femur
triangles). FIG. 8(b) is an exploded drawing of the parts A to D
and A' to D' of the skin.
[0126] FIG. 9(a) is a drawing in which the thigh areas and the
belly are seen from the front side when the wearer takes the
knee-raised position. Also, FIG. 9(a) shows A to D and A' to D' of
skin parts (the parts on the front and inner sides in the thigh
areas including the femur triangles). FIG. 9(b) is an exploded
drawing of the parts A to D and A' to D' of the skin.
[0127] FIG. 11(a) is a drawing in which the legs and the belly are
seen from the front side when the wearer is standing. Also, FIG.
11(a) shows E to G and E' to G' of skin parts (the lumbar and the
hip part). FIG. 11(b) is an exploded drawing of the skin parts E to
G and E' to G'.
[0128] FIG. 12(a) is a drawing in which the legs and the belly are
seen from the front side when the wearer is in the knee-raised
position. Also, FIG. 12(a) shows E to G and E' to G' of skin parts
(the lumbar and the hip part). FIG. 12(b) is an exploded drawing of
the skin parts E to G and E' to G'.
[0129] The stretch of the skin parts on the front side of the
wearer is described.
[0130] As shown in FIG. 10, when the part A shown in FIG. 8(the
right side part in the standing position) and the part A shown in
FIG. 9 (the right side part in the knee-raised position) are
compared with each other, the area becomes approximately 200%
(precisely, 196.7%) with the movement from the standing position to
the knee-raised position. Also, with the movement from the standing
position to the knee-raised position, the length of the part A (the
dimension in the lateral direction in FIG. 9(b)) becomes
approximately doubled.
[0131] When the part B shown in FIG. 8 (the right side part in the
standing position) and the part B shown in FIG. 9(the right side
part in the knee-raised position) are compared with each other, the
area becomes approximately 80% (precisely, 80.1%) with the movement
from the standing position to the knee-raised position.
[0132] When the part C shown in FIG. 8 (the right side part in the
standing position) and the part C shown in FIG. 9(the right side
part in the knee-raised position) are compared with each other, the
area shows almost no change (precisely, it becomes 104.3%) even
with the movement from the standing position to the knee-raised
position.
[0133] When the part D shown in FIG. 8 (the right side part in the
standing position) and the part D shown in FIG. 9(the right side
part in the knee-raised position) are compared with each other, the
area becomes approximately 140% (precisely, 136.7%) with the
movement from the standing position to the knee-raised
position.
[0134] When the part A' shown in FIG. 8 (the left side part in the
standing position) and the part A' shown in FIG. 9(the left side
part in the knee-raised position) are compared with each other, the
area becomes approximately 160% (precisely, 162.7%) with the
movement from the standing position to the knee-raised position.
Also, with the movement from the standing position to the
knee-raised position, the length (the dimension in the lateral
direction in FIG. 9(b)) becomes approximately 1.7 to 1.8 times.
[0135] When the region B' shown in FIG. 8(the left side part in the
standing position) and the part B' shown in FIG. 9 (the left side
part in the knee-raised position) are compared with each other, the
area becomes approximately 90% (precisely, 85.9%) with the movement
from the standing position to the knee-raised position.
[0136] When the part C' shown in FIG. (the left side part in the
standing position) and the part C' shown in FIG. 9(the left side
part in the knee-raised position) are compared with each other, the
area becomes approximately 110% (precisely, 114.8%) with the
movement from the standing position to the knee-raised
position.
[0137] When the part D' shown in FIG. 8 (the left side part in the
standing position) and the part D' shown in FIG. 9(the left side
part in the knee-raised position) are compared with each other, the
area becomes approximately 140% (precisely, 142.9%) with the
movement from the standing position to the knee-raised
position.
[0138] The stretch of the skin parts on the back side of the wearer
is described.
[0139] As shown in FIG. 13, when the part E shown in FIG. 11(the
left side part in the standing position) and the part E shown in
FIG. 12(the left side part in the knee-raised position) are
compared with each other, the area becomes approximately 130%
(precisely, 134.5%) with the movement from the standing position to
the knee-raised position.
[0140] When the part F shown in FIG. 11 (the left side part in the
standing position) and the part F shown in FIG. 12 (the left side
part in the knee-raised position) are compared with each other, the
area becomes approximately 120% (precisely, 120.3%) with the
movement from the standing position to the knee-raised
position.
[0141] When the part G shown in FIG. 11 (the left side part in the
standing position) and the part G shown in FIG. 12(the left side
part in the knee-raised position) are compared with each other, the
area becomes approximately 220% (precisely, 222.5%) with the
movement from the standing position to the knee-raised position.
Also, with the movement from the standing position to the
knee-raised position, the length (the dimension in the vertical
direction in FIG. 12(b)) becomes approximately 2.2 times.
Furthermore, as it can be seen from the diamond shaped slit in the
part G shown in FIG. 11(b) from the "V"-letter shaped cutout in the
part G shown in FIG. 12(b), the form of the part G (the
three-dimensional form) is also changed.
[0142] As can be seen from FIG. 11(b) and FIG. 12(b), the stretches
of the skin are substantially equal to each other on the left and
right sides on the back side of the wearer.
[0143] When the worker is in the squat-down position, particularly
in the position with open legs, the skin of the wearer is stretched
(contracted) as described above. Accordingly, to obtain a sense of
comfort when the wearer of the trousers 1 takes the squat-down
position, the stretchable material (the stretchable member) has to
be provided according to the aforementioned stretch and contraction
of the skin.
[0144] Since the trousers 1 is provided with the stretchable
material 3 in the thigh region (thing area) of the front body, the
stretchable material 3 stretches following the stretch of the skin
parts A, A' sown in FIG. 8 and FIG. 9. Thus, the sense of tightness
or tight fit in the thigh portion can be prevented and the sense of
comfort can be secured.
[0145] In the trousers 1, the stretchable material 3 provided on
the back side of the lumbar also stretches in the back body, and
the stretchable material 3 stretches following the stretch of the
skin parts G, G' shown in FIG. 11 and FIG. 12. Thus, the sense of
tightness or tight fit on the backside of the lumbar can be
prevented and the sense of comfort can be secured.
[0146] And now, in FIG. 14 and FIG. 15, the skin parts A, A' and
the skin part G, G' are not overlapped with the stretchable
material 3. However, since the stretchable material 3 stretches
along with the stretch of the parts A, A' and G, G', the sense of
tightness or tight fit can be prevented.
[0147] For example, the wearer of the trousers 1 wears underwear.
Accordingly, the skin of the wearer does not come into direct
contact with the parts A, A' and the parts G, G' of the trousers 1.
In addition, even when the wearer sweats, the trousers 1 does not
stick to the skin of the wearer (the parts A, A' or the parts G,
G'). Accordingly, even though the parts A, A' and the parts G, G'
are not overlapped with the stretchable material 3, the stretchable
material 3 stretches in place of the regions of the trousers 1 for
the parts A, A' or the parts G, G' (the regions formed of the cloth
of the trousers 1 which overlap with the parts A, A' and the parts
G, G'), when the wearer is in the squat-down position. Thus, the
sense of tightness or tight fit can be prevented.
[0148] Furthermore, even though the wearer of the trousers 1 keeps
the squat-down position for a long period of time, the stretchable
material 3 stretches as needed and accordingly the blood vessel of
the legs are hardly compressed. Thus, there is no possibility of
losing balance when standing up. Also, when the wearer of the
trousers 1 is in the squat-down position, the stretchable material
3 stretches as needed, which does not cause the sense of tightness.
Accordingly, the wearer can smoothly take the squat-down position
and there is no possibility of losing the balance when moving to
take the squat-down position. As a result, the occurrence of
accidents of falling from the roof can be suppressed.
[0149] In addition, with the trousers 1, when the wearer of the
trousers 1 climbs a ladder with the legs being bent and lifted, the
stretchable material 3 stretches as needed. Thus, the sense of
tightness due to the bending of the legs can be prevented. As a
result, the accidents of falling from the roof can be
suppressed.
[0150] Furthermore, with the trousers 1, the stretchable material 3
stretches as needed when the wearer of the trousers 1 takes the
squat-down position. Accordingly, there is not such a case that the
belly portion is not compressed by a belt and the backbone is
compressed with the compression. Thus, the occurrence of the
strained back due to the compression of the belly portion or the
backbone can be avoided.
[0151] And now, the above description is about the trousers (lower
wear), but the stretchable material 3 may be provided in an overall
61. In other words, in the overall 61 including an upper wear
portion (a jacket portion) 65 and trousers portion 63 (see, FIG. 17
and FIG. 18), any change may be made in such a manner, for example,
the trousers portion 63 is formed as similar to the trousers 1 or a
body of the overall (the overall shown in FIG. 17 and FIG. 19) is
provided with cargo pockets 59. FIG. 18 is an exploded drawing of
the overall 61. The reference signs same as those of the trousers 1
shown in FIG. 4 are given to denote portions of the trousers
portion 63.
[0152] The overall 61 in which the trousers portion 63 is formed
similarly to the trousers 1 is symmetrically formed similarly to
the trousers 1.
[0153] Also, the overall 61 (the upper wear portion 65) is provided
with a belt-like stretchable material (an upper wear shoulder front
stretchable material) 67. The upper wear shoulder front stretchable
material 67 is a portion from a neck base diagonally-front region
69 to an armpit front region 73 via an arm base front region 71 of
a wearer and constitutes a part of the upper wear portion 65.
[0154] The neck base diagonally-front region 69 is a region for a
part that is at the neck base of the wearer (a boundary between the
neck and a trunk or a portion slightly below the boundary) and is
located diagonally in front. The arm base front region 71 is a
region for a part that is at an arm base of the wearer (a boundary
between the arm and the trunk) and is located on the front side.
The armpit front region 73 is a region for a part that is at the
armpit of the wearer and is located on the front side.
[0155] More specifically, the overall 61 is symmetrically formed.
Accordingly, the upper wear shoulder front stretchable material 67
includes the upper wear shoulder right front stretchable material
67R and the upper wear shoulder left front stretchable material
67L. Then, the upper wear shoulder right front stretchable material
67R is provided extending from the neck base diagonally-right-front
region 69R to the armpit right front region 73R via the arm base
right front region 71R.
[0156] The neck base right front region 69R is a region for a part
that is at the neck base of the wearer and is located diagonally in
right front of the wearer. The arm base right front region 71R is a
region for a part that is at the right arm base of the wearer and
located on the front side of the wearer (substantially the center
of the right arm base in the vertical direction). The armpit right
front region 73R is a region for the front side part of the right
armpit of the wearer.
[0157] The longitudinal direction of the upper wear shoulder right
front stretchable material 67R is a direction in which the upper
wear shoulder right front stretchable material 67R is extended (the
direction passing from the neck base diagonally-right-front region
69R to the armpit right front region 73R via the arm base right
front region 71R). The width direction of the upper wear shoulder
right front stretchable material 67R is a direction substantially
perpendicular to the longitudinal direction of the upper wear
shoulder right front stretchable material 67R.
[0158] The width of the upper wear shoulder right front stretchable
material 67R is not constant, for example, but decreases at the
neck base diagonally-right-front region 69R and gradually increases
toward the arm base right front region 71R, and then gradually
decreases toward the armpit right front region 73R. In other words,
a value of the width of the upper wear shoulder right front
stretchable material 67R smoothly changes, and is small on the both
ends of the longitudinal direction and is large on the center
portion of the longitudinal direction.
[0159] The upper wear shoulder left front stretchable material 67L
is provided to be symmetrical with the upper wear shoulder right
front stretchable material 67R.
[0160] Also, the overall 61 (the upper wear portion 65) is provided
with a belt-like stretchable material (the upper wear shoulder back
stretchable material) 75. The upper wear shoulder back stretchable
material 75 is a portion passing from a neck base diagonally-back
region 77 to an armpit back portion 81 via an arm base back region
79 of a wearer and constitutes a part of the upper wear portion
65.
[0161] The neck base diagonally-back region 77 is a region for a
part that is at the neck base (a boundary between the neck and a
trunk or a portion slightly below the boundary) and is located
diagonally in back.
[0162] The arm base back side region 79 is a region for a part that
is at an arm base and is located on the back side.
[0163] The armpit back region 81 is a region for a part that is at
the armpit and is located on the back side.
[0164] More specifically, the overall 61 is symmetrically formed.
Accordingly, as similar to the upper wear shoulder front
stretchable material 67, the upper wear shoulder back stretchable
material 75 also includes the upper wear shoulder right back
stretchable material 75R and the upper wear shoulder left back
stretchable material 75L. Then, the upper wear shoulder right back
stretchable material 75R is provided extending from the neck base
diagonal right back region 77R to the armpit right back region 81R
via the arm base right back region 79R.
[0165] The neck base right back region 77R is a region for a part
that is at the neck base of the wearer and is located diagonally in
right back of the wearer. The arm base right back region 79R is a
region for a part that is at the right arm base of the wearer and
is located on the back side of the wearer (substantially the center
of the right arm base in the vertical direction). The armpit right
back region 81R is a region for the back side part of the right
armpit of the wearer.
[0166] The longitudinal direction of the upper wear shoulder right
back stretchable material 75R is a direction in which the upper
wear shoulder right back stretchable material 75R is extended (the
direction passing from the neck base diagonal right back region 77R
to the armpit right back region 81R via the arm base right back
region 71R). The width direction of the upper wear shoulder right
back stretchable material 75R is a direction substantially
perpendicular to the longitudinal direction of the upper wear
shoulder right back stretchable material 75R.
[0167] The width of the upper wear shoulder right back stretchable
material 75R is not constant, for example, but as similar to the
upper wear shoulder right front stretchable material 67R, and
increases at the center of the longitudinal direction and decreases
on the both ends.
[0168] The upper wear shoulder left back stretchable material 75L
is provided so as to be symmetrical with the upper wear shoulder
right back stretchable material 75R.
[0169] Note that in the overall 61, the upper wear shoulder right
front stretchable material 67R (the upper wear shoulder left front
stretchable material 67L) and the upper wear shoulder right back
stretchable material 75R (the upper wear shoulder left back
stretchable material 75L) are not connected with each other (are
separated at the armpit portion of the wearer), but the upper wear
shoulder right front stretchable material 67R (the upper wear
shoulder left front stretchable material 67L) and the upper wear
shoulder right back stretchable material 75R (the upper wear
shoulder left back stretchable material 75L) may be connected with
each other (may be connected at the armpit portion of the
wearer).
[0170] Also, one or both of the upper wear shoulder front
stretchable material 67 and the upper wear shoulder back
stretchable material 75 may be excluded. FIG. 19 is a drawing
showing the overall 61 whose upper wear shoulder front stretchable
material 67 is omitted, which corresponds to FIG. 17.
[0171] Also, the overall 61 (the upper wear portion 65) is provided
with a belt-like stretchable material (the upper wear trunk
stretchable material) 83. The upper wear trunk stretchable material
83 is a portion passing from an upper lumbar region 85 to a
diagonally-front belly region 89 via a side belly region 87 and
constitutes a part of the upper wear 65.
[0172] The upper lumbar region 85 is a region for the lumbar of the
wearer (an upper part of the lumbar). The side belly region 87 is a
region for a side belly part of the wearer. The diagonally-front
belly region 89 is a region for a diagonally-front belly part of
the wearer.
[0173] More specifically, since the overall 61 is formed
symmetrically, the upper wear trunk stretchable material 83 is
provided extending from the diagonally-right-front belly region
89R, the right side belly region 87R, the upper lumbar region 85,
the left side belly region 87R, and the diagonally-left-front belly
region 89L in this order.
[0174] The diagonally-right-front belly region 89R is a region for
apart away from the navel of the wearer to the right by a
predetermined distance (for example, approximately 10 cm). The
right side belly region 87R is a right region for the right belly
of the wearer (a part located in substantially the same height
direction the naval and in the boundary between the belly and the
back). The upper lumbar region 85 is a region for a part right
behind the wearer on the upper side of the lumbar of the
wearer.
[0175] The left side belly region 87L is a left region for the left
belly of the wearer (a part located in substantially the same
height direction the naval and in the boundary between the belly
and the back). The diagonally-left-front belly region 89L is a
region for a part away from the navel of the wearer to the left by
a predetermined distance (for example, approximately 10 cm).
[0176] The longitudinal direction of the upper wear trunk
stretchable material 83 is a direction provided by extending the
upper wear trunk stretchable material 83 (the direction from the
diagonally-right-front belly region 89R, to the right side belly
region 87R, the upper lumbar region 85, the left side belly region
87L, and the diagonally-left-front belly region 89L, in this
order). The width direction of the upper wear trunk stretchable
material 83 is a direction substantially perpendicular to the
longitudinal direction of the upper wear trunk stretchable material
83.
[0177] The width of the upper wear trunk stretchable material 83 is
not constant, for example, but as similar to the upper wear
shoulder right front stretchable material 67R, and increases at the
center of the longitudinal direction and decreases on the both
ends.
[0178] If the wearer and the overall 61 are seen in the planar view
when the wearer wears the overall 61, the upper wear trunk
stretchable material 83 is in a "C"-letter shape with the front
side of the wearer being open.
[0179] Note that the upper wear trunk stretchable material 83 and
the stretchable material 3 (3R, 3L) of the trousers portion 63 are
spaced apart from each other with the waist band cloth 91 being
therebetween, but the upper wear trunk stretchable material 83 and
the stretchable material 3 of the trousers portion 63 may be
connected with each other. In other words, the pants-side
stretchable material 3 and the upper wear trunk stretchable
material 83 may be connected with each other at the region 93 shown
in FIG. 17(b) (the region with a predetermined width narrower than
the width of the lumbar). Furthermore, the pants-side stretchable
material 3 and the upper wear trunk stretchable material 83 may be
formed of an integral stretchable material.
[0180] The overall 61 is further described by referring to FIG. 18.
Note that only right side portion of the overall 61 is exploded in
FIG. 18. Also, the cloth shown in FIG. 18 in which double
semi-circle 95 is drawn (including the stretchable material) is
formed symmetrical with respect to a line segment 97 in which the
double semi-circle 95 is drawn.
[0181] In other words, in the overall 61, the trousers side
stretchable material 3, the waist band cloth 91, an upper trunk
portion stretchable material 83, a back center body cloth 99, and a
collar cloth 101 are actually symmetrical with respect to the line
segment 97.
[0182] Also, the overall 61 is formed of cloths forming the right
front body 103 (103R), the right upper sleeve cloth 105(105R), the
right lower sleeve cloth 107 (107R), and the trousers portion 63,
and each cloth shown in FIG. 18 and each cloth in symmetry thereof
(each cloth on the left side) are sewed up together as needed to
create the overall 61.
[0183] And now, in the trousers 1 shown in FIG. 1 and the like, the
left and right stretchable materials 3R, 3L are divided, and the
left and right stretchable materials 3R, 3L are sewed up together
to create the trousers 1. However, in the trousers 1 shown in FIG.
1 and the like, the left and right stretchable materials 3R, 3L may
be integrally formed without being divided.
[0184] Also, the upper wear trunk stretchable material 83 shown in
FIG. 18 is integrally formed. However, the upper wear trunk
stretchable material 83 shown in FIG. 18 may be divided into left
and right parts, and the divided left and right upper wear trunk
stretchable materials may be sewed up together to form the upper
wear trunk stretchable material.
[0185] The overall 61 is provided with the upper wear shoulder
front stretchable material 67 and the upper wear shoulder back
stretchable material 75, so that the upper wear shoulder front
stretchable material 67 and the upper wear shoulder back
stretchable material 75 stretch when the wearer moves the arms of
the wearer. Thus, the arms can be easily moved.
[0186] Also, the overall 61 is provided with the upper wear trunk
stretchable material 83, so that the upper wear trunk stretchable
material 83 stretches when the wearer bends the waist of the
overall 61. Thus, the waist can be easily moved.
[0187] Note that the overall 61 shown in FIG. 17 and the like are a
long sleeve type, but the overall may be a short sleeve type or a
sling type (a running type).
[0188] Also, in the overall 61, the trousers portion 63 may be
deleted and only the upper wear 65 is left, which may be used as an
upper wear.
