Technical Field
[0001] The present invention relates to a garment, and particularly to a garment worn attached
to a body.
Background Art
[0002] A girdle, a body suit, a brassiere, a swim suit, shorts, and other conventional garments
that are worn attached tightly to a body have a tightening portion formed on a predetermined
section of such garments in order to manipulate the body shape of a wearer, correct
the wearer's posture, and improve the wearer's motor ability by means of the tightening
force of the tightening portion. In order to form a garment having such a tightening
portion, a filler cloth is applied to a part of the garment to provide a strong tightening
force, or the thickness of an elastic yarn to be knitted is made thicker. However,
application of a filler cloth is not preferred, since the thickness of the fabric
of the tightening portion increases by the thickness of the filler cloth. Also, when
forming the tightening portion by increasing the thickness of the elastic yarn to
be knitted, the border between the parts with different tightening forces extends
only in a direction in which the elastic yarn is knitted, and thus a desired shape
of tightening portion cannot be obtained.
[0003] Therefore, as described in Patent Document 1, regarding the knit structure of the
fabric, a part to be provided with the tightening force is formed into a satiny structure,
and other parts into a mesh-like structure, so that a desired shape of tightening
portion is obtained without using a filler cloth.

[Problems to be Solved by the Invention]
[0004] However, in the technology of Patent Document 1, the difference in magnitude of tightening
force to be obtained is based on the difference in types of the knit structures, thus
a large difference between the sections with and without the filler cloth when the
filler cloth is used cannot be obtained. Moreover, in order to secure a difference
in tightening force between the knit structures of a knit fabric, flexibility in adopting
the knit structures decreases. The present invention has been contrived to solve the
aforementioned problems, and its object is to provide a garment that is capable of
obtaining a desired shape of tightening portion without using a filler cloth, and
obtaining a sufficient difference in tightening force between sections to be and not
to be provided with a strong tightening force, and that has a small limitation in
adopting a ground structure serving as a base of a knitted fabric.
[Means for Solving the Problems]
[0005] In order to achieve this object, the garment of the present invention is a garment
attached tightly to a body, comprising a belt-like tightening portion that has a strong
tightening portion, which is a part having a relatively strong tightening force, and
a weak tightening portion, which is a part having a relatively weak tightening force,
where the strong tightening portion and the weak tightening portion are switched in
a belt-like longitudinal direction, wherein, in the tightening portion, a yarn for
reinforcing the tightening force is continuously knitted into a ground structure throughout
the strong tightening portion and the weak tightening portion, and a knit structure
of the yarn for reinforcing the tightening force has a greater number of looping structures
in the strong tightening portion than the weak tightening portion, and has a greater
number of insertion structures in the weak tightening portion than the strong tightening
portion.
[0006] According to this garment, the yarn for reinforcing the tightening force is continuously
knitted into the ground structure in the belt-like tightening portion, so that the
strong tightening portion is formed mainly by the looping structures and the weak
tightening portion is formed mainly by the insertion structures. Therefore, the strong
tightening portion is formed into a desired shape at an appropriate position of the
knitted fabric, and a sufficient difference in the tightening force between the strong
tightening portion and the other portion and also between the strong tightening portion
and the weak tightening portion can be obtained.
[0007] Furthermore, the garment of the present invention is a garment attached tightly to
a body, comprising a belt-like tightening portion, wherein the tightening portion
and at least a part of a fabric main body portion that is adjacent to the tightening
portion comprise a common ground structure, the tightening portion has a strong tightening
portion, which is a part having a relatively strong tightening force, and a weak tightening
portion, which is a part having a relatively weak tightening force, where the strong
tightening portion and the weak tightening portion are switched in a belt-like longitudinal
direction, in the tightening portion, a yarn for reinforcing the tightening force
is continuously knitted into a ground structures throughout the strong tightening
portion and the weak tightening portion, and a knit structure of the yarn for reinforcing
the tightening forces has a greater number of looping structures in the strong tightening
portion than the weak tightening portion, and has a greater number of insertion structures
in the weak tightening portion than the strong tightening portion.
[0008] In this case, in the garment of the present invention the yarn for reinforcing the
tightening force is continuously knitted into the ground structure in the belt-like
tightening portion, so that the strong tightening portion is formed mainly by the
looping structures and the weak tightening portion is formed mainly by the insertion
structures. Therefore, the strong tightening portion is formed into a desired shape
at an appropriate position of the knitted fabric, a sufficient difference in the tightening
force between the strong tightening portion and the other portion and also between
the strong tightening portion and the weak tightening portion can be obtained, and
the ground structure can be obtained as a structure that is common between the tightening
portion and the fabric main body portion which is adjacent to the tightening portion.
[0009] Moreover, the garment of the present invention is a garment attached tightly to a
body, comprising a belt-like tightening portion, wherein a fabric main body portion
comprises a plurality of knitted fabric parts that are formed respectively from ground
structures having different tightening forces, and border lines of the plurality of
knitted fabric parts intersect with the belt-like tightening portion, the tightening
portion has a strong tightening portion, which is a part having a relatively strong
tightening force, and a weak tightening portion, which is a part having a relatively
weak tightening force, where the strong tightening portion and the weak tightening
portion are switched in a belt-like longitudinal direction, in the tightening portion,
a yarn for reinforcing the tightening force is continuously knitted into each of the
ground structures throughout the strong tightening portion and the weak tightening
portion, and a knit structure of the yarn for reinforcing the tightening forces has
a greater number of looping structures in the strong tightening portion than the weak
tightening portion, and has a greater number of insertion structures in the weak tightening
portion than the strong tightening portion, and out of the plurality of knitted fabric
parts, a knitted fabric part with a relatively strong tightening force overlaps with
at least a part of the strong tightening portion.
[0010] In this case, in the garment of the present invention the yarn for reinforcing the
tightening force is continuously knitted into the ground structure in the belt-like
tightening portion, so that the strong tightening portion is formed mainly by the
looping structures and the weak tightening portion is formed mainly by the insertion
structures. Therefore, the strong tightening portion is formed into a desired shape
at an appropriate position of the knitted fabric, and a sufficient difference in the
tightening force between the strong tightening portion and the other portion and also
between the strong tightening portion and the weak tightening portion can be obtained,
Moreover, the fabric main body portion is configured by a plurality of knitted fabric
portions that are formed by the ground structures having different tightening forces,
wherein a part where the knitted fabric portion with a strong tightening force overlaps
with the strong tightening portion can produce a strong tightening force by means
of the tightening forces of the both overlapping each other.
[0011] When the strong tightening portion has a part inclined in the longitudinal direction
of the weak tightening portion, the pressure at a particularly strong tightening portion
can be alleviated because the entire tightening portions are not formed into rings
of the same circumference.
[0012] Note that the garment attached to the body as described in the present specification
is applied not only to a case where the garment is attached in direct contact with
the body surface but also a case where the garment is attached to the body via an
inner cloth.
[0013] The present invention can provide a garment that is worn attached tightly to a body
and has improved freedom of design in terms of the tightening force or shape of a
tightening portion that manipulates the body shape of a wearer, corrects the wearer's
posture, and improves the wearer's motor ability.

Best Modes for Carrying Out the Invention
[0016] Hereinafter, a preferred embodiment of the garment of the present invention is described
in detail. Note that through the explanation the same reference numerals are applied
to the same elements or the elements with the same function, and overlapping explanation
is omitted. Fig. 1 is a perspective view in which a girdle 1 of the present invention,
an example of a garment worn attached to a body, is viewed from its front side. Note
that in the following explanation "tightening portion" is a part configured from a
fabric with lower stretchability than that of a fabric main body portion, and produces
higher pressure than the periphery when the garment is worn. This pressure is called
"tightening force."
[0017] Right and left bodies 2 of the girdle 1 each have two belt-like tightening portions
32a, 32b extending in a horizontal direction on a section corresponding to a thigh
portion thereof. In these tightening portions 32a, 32b, the hatched parts surrounded
by solid lines have relatively strong tightening force compared to weak tightening
portions 322a, 322b as will be described hereinafter, and thus are called "strong
tightening portions 321a, 321b." The parts that are surrounded by solid lines but
are not hatched and extend to the right and left of the strong tightening portions
321a, 321b have relatively weak tightening force compared to the strong tightening
portions 321a, 321b, and thus are called "weak tightening portions 322a, 322b." The
strong tightening portion 321a and the weak tightening portion 322a form one continuous
belt, and the strong tightening portion 321b and the weak tightening portion 322b
similarly form one continuous belt. A central part of the upper strong tightening
portion 321 a is convexed downward (and concaved upward) so as to have a part inclined
in a longitudinal direction of the weak tightening portion 322a, and a central part
of the lower strong tightening portion 321b is convexed upward (and concaved downward)
so as to have a part inclined in a longitudinal direction of the weak tightening portion
322b. Then, the strong tightening portions 321a, 321b forming a horizontally long
X shape are formed by superposing the both of the above-described convexed and concaved
parts.
[0018] The strong tightening portions 321a, 321b each are located in a position corresponding
to a front central part of each thigh of a wearer. Therefore, the wearer's quadriceps
muscle positioned in each of the strong tightening portions 321a, 321b of the girdle
1 is strongly tightened and stimulated. Also, the weak tightening portions 322a, 322b
having a relatively weak but larger tightening force than the fabric main body portion
31 are located at the extensions of the strong tightening portions 321a, 321b. Therefore,
the entire thighs are also tightened sufficiently and, particularly, the quadriceps
muscle of the front central part of each thigh is strongly tightened so that the legs
of the wearer can kick largely when walking, whereby a beautiful body shape can be
maintained. Moreover, the strong tightening portions 321a, 321b are formed into the
shape of an X having a part inclined in the longitudinal direction of the weak tightening
portions 322a, 322b. Therefore, compared to a case where the strong tightening portions
321a, 321b are in the form of strait lines extending in the same circumference, the
two strong tightening portions 321a, 321b concentrate on the central parts of the
thighs of the wearer without compressing the thighs in the form of a ring, and thereby
a tightening force can be dispersed in horizontal and vertical directions.
[0019] Next, a fabric 3 configuring the body 2 of the girdle 1 is described with reference
to Fig. 2. Fig. 2 is a schematic diagram showing one unit of fabric 3 for creating
the body 2 on the left side of the girdle 1. The fabric 3 is a warp knitted fabric
knitted by yarns supplied in the direction shown by the arrow S, and has the two belt-like
tightening portions 32a, 32b formed at a part of the fabric main body portion 31 configured
by a ground structure. The tightening portions 32a, 32b are configured by the strong
tightening portions 321a, 321b and the weak tightening portions 322a, 322b as described
with reference to Fig. 1. Furthermore, hems 33 for preventing raveling of the yarns
are formed at upper and lower edges respectively. In order to produce the girdle 1,
the left body 2 is cut from the fabric shown in Fig. 2, similarly the right body 2
is cut from a fabric symmetric with the one shown in Fig. 2, and these bodies 2, an
abdominal cloth 4 and a crotch are stitched together.
[0020] Next, Fig. 3 shows a state in which eight units of the fabric 3 of Fig. 2 are integrated
by a warp-knitting machine. The fabrics 3 are disposed such that two units thereof
are disposed in a long-side direction and four units in a short-side direction. The
hems 33 are formed on the borders on the long sides of each fabric 3. The fabrics
3 on both sides of one yarn located at the center in the width direction of the hems
33 are knitted into a knitted fabric, which is configured such that these fabrics
3 can be separated from each other with the divided hems 33, by pulling the yarn.
A border 34 on a short side of each fabric 3 is formed so as to be distinguishable,
by changing the knit structure from the after-described ground structure to 1 x 1
tricot structure by six courses. The eight units are knitted simultaneously and integrally
by the warp-knitting machine. The direction of knitting at this moment is shown by
the arrow S.
[0021] Before explaining the knit structure of the knitted fabric according to the present
embodiment, the knit structure and an organizational diagram will be described first
based on Fig. 4. In Fig. 4, black dots represent the positions of needle heads in
each course, and a space between black dots in a horizontal direction represents a
needle space portion. A row of black dots arranged in the horizontal direction represents
one course and shows how one yarn can be knitted in each of the courses C 1 through
Cn when the yarn is supplied in the direction of the arrow S.
[0022] Moreover, the knit structure is divided largely into two structures: a looping structure
and an insertion structure. The looping structure is a structure for forming a loop
by guiding a yarn using a guide bar and then wrapping the yarn. When the loops intersect
with each other to form a closed stitch, this stitch is called "closed loop," and
when the loops are opened without intersecting with each other, thus obtained stitch
is called "open stitch." Yarns Ya through Yd shown in Fig. 4 each are an example of
the looping structure, wherein the yarns Ya and Yd are the looping structures configured
by the closed loops in all courses, while the yarns Yb and Yc each are the looping
structures configured by the open loops in all courses. Furthermore, in order to represent
the knitting of the yarns by means of the positions of the needle space portions,
numbers 1, 2, 3 and the like are applied in this order to the left, with the right-most
needle space portion through which each yarn is guided and caused to pass by the guide
bar is 0 (sometimes 0, 2, 4, 6 and the like are used depending on the type of the
knitting machine). For example, in the case of the yarn Ya, it moves from the needle
space portion 1 to the needle space portion 2 in the course C1, moves from the needle
space portion 1 to the needle space portion 0 in the course C2, and thereafter repeats
this movement, hence this movement is expressed as "1, 2/1, 0//." The knit structure
of the yarn Ya is called "1/1 tricot structure" or "denbigh structure." Also, the
structures of the yarns Yc, Yd are called "chain structure."
[0023] The insertion structure is a structure in which an insertion yarn is inserted into
other structure. The insertion yarn itself does not form a stitch and is laid between,
for example, a needle loop and a sinker loop of other structure. Yarns Ye and Yf shown
in Fig. 4 are examples of the insertion structure. The yarn Ye is an insertion structure
moving alternately in adjacent two needle space portions only, such that the guide
bar swings in and out of the position of the needle space portion 1 in the course
C1, swings in and out at the position 0 in the course 2, and thereafter repeats this
movement, hence this movement is expressed as "1, 1/0, 0//." The yarn Yf is an insertion
structure that is caused to swing in the horizontal direction (course direction) in
one needle space portion, and thus is expressed as "2, 2/0, 0//."
[0024] Next, the knit structures according to the present embodiment is described with reference
to Fig. 5 through Fig. 7. Note that in order to obtain the knitted fabric of the present
embodiment, a knitting machine such as RSE5EL manufactured by Karl Mayer Co. can be
used. Fig. 5 shows the knit structure, which is the knit structure of the fabric main
body portion 31 of the fabric 3 and is also the ground structure of the knitted fabrics
of the tightening portions 32a, 32b. A yarn Y1 is, for example, a nylon yarn of 56
dtex, which is caused to pass through a guide bar of a comb L1 and supplied in the
direction of the arrow S to perform knitting. In all of the courses, the closed loops
are formed, and six courses C1 through C6 consist one repeating unit R, which is expressed
as "1, 2/1, 2/1, 2/1, 0/1, 0/1, 0//." A yarn Y2 is a polyurethane yarn of 310 dtex,
which is caused to pass through a guide bar of a comb L2 and supplied in the direction
of the arrow S to perform knitting. All of the courses consist an insertion structure,
wherein the six courses C1 through C6 consist one repeating unit R, which is expressed
as "2, 2/1, 1/3, 3/1, 1/2, 2/0, 0//."
[0025] These yarns Y1 and Y2 are knitted at the positions of all needle points, whereby
a satin ground structure of the fabric 3 is knitted. This state is shown as an organizational
diagram in Fig. 6. However, the ground structure of the fabric 3 is not limited to
those shown in Figs. 5 and 6, and thus 1/1 tricot structure, 1/2 tricot structure,
1/3 tricot structure, structure having a combination of these structures, a combination
of a chain structure and an insertion structure, or other appropriate structure can
be adopted. Moreover, the thickness or types of the yarns can also be selected appropriately.
[0026] Fig. 7 is an organizational diagram showing how the yarns are knitted into the ground
structure in order to reinforce the tightening force. Yarn Y3 and yarn Y4 each are
a FTY 22t x 33t elastic yarn obtained by twisting a 33 dtex nylon yarn around a 22
dtex polyurethane yarn as a wick. The reason for using such yarn having a polyurethane
yarn and a nylon yarn entwined with each other is to reduce the difference in dyeing
effect between the fabric main body portion and this yarn, which is caused by the
fact that the dyeing characteristics of the polyurethane yarn is poorer than those
of the nylon yarn. Moreover, a yarn of an appropriate type and thickness can be adopted
as the yarn Y3 and yarn Y4. For example, a thick yarn can be adopted as the yarn Y3
and yarn Y4 for obtaining stronger tightening force.
[0027] The yarn Y3 is caused to pass through the guide bar of a comb L3, supplied in the
direction of the arrow S, and knitted. The yarn Y4 is caused to pass through the guide
bar of a comb L4, supplied in the direction of the arrow S, and knitted. Specifically,
the yarn Y4 shown in Fig. 7 is knitted into all wales in the belt of the tightening
portion 32a formed continuously from the bottom to the top in the order of the weak
tightening portion 322a, strong tightening portion 321a, weak tightening portion 322a,
strong tightening portion 321a, and weak tightening portion 322a, as shown in Fig.
3. Similarly, the yarn Y3 shown in Fig. 7 is knitted into all wales in the belt of
the tightening portion 32b formed continuously from the bottom to the top in the order
of the weak tightening portion 322b, strong tightening portion 321b, weak tightening
portion 322b, strong tightening portion 321b, and weak tightening portion 322b, as
shown in Fig. 3.
[0028] These yarns Y3 and Y4 are knitted simultaneously with the yarn Y1 and the yarn Y2
that form the ground structures, but these yarns are explained separately for the
convenience of explanation. The yarn Y3 and yarn Y4 in the courses of a range A1 are
both knitted into the ground structure knitted by the yarns Y1 and Y2, in the form
of the insertion structure "1, 1/0, 0//" where a yarn moves between only two adjacent
needle space portions alternately. This section corresponds to the weak tightening
portions 322a and 322b located at the bottom of the fabric 3 shown in Fig. 3, wherein
the yarn Y3 is knitted into the weak tightening portion 322b and the yarn Y4 into
the weak tightening portion 322a. Since the structures of the yarn Y3 and yarn Y4
are the insertion structures where a yarn moves between only the adjacent two needle
space portions alternately, the quantity of required yarns is small and the quantity
of yarns to be supplied is controlled to a small quantity by an electronic control
device. Since the yarn Y3 and yarn Y4 are knitted into the ground structure knitted
by the yarn Y1 and yarn Y2, the weak tightening portions 322a, 322b are formed into
fabrics denser than the peripheral fabric main body portion 31 formed only by the
ground structures and thus generate a strong tightening force. However, compared to
the strong tightening portions 321a, 321b described hereinafter, the weak tightening
portions 322a, 322b have low density and relatively small tightening force and thus
are not as visually apparent as the strong tightening portions 321a, 321b.
[0029] The yarn Y3 and yarn Y4 gradually shift so as to approach each other on the basis
of the chain structures in the courses within a range A2. Then, in the courses within
a range A3, the yarn Y3 and yarn Y4 are formed by only the linear chain structures
that are parallel to each other. Although not illustrated in Fig. 7, in the courses
within the range next to the range A3, as opposed to A2, the structure to shift in
the direction spreading each other on the basis of the chain structures is continued.
The range from A2 to this range corresponds to the substantially X-shaped strong tightening
portions 321a, 321b shown in Fig. 3, wherein the yarn Y3 is knitted into the strong
tightening portion 321b, and the yarn Y4 into the strong tightening portion 321a.
Since the yarn Y3 and yarn Y4 configure the looping structures, the quantity of required
yarns is large, and the quantity of yarns to be supplied is controlled to a large
quantity by the electronic control device. Therefore, in the strong tightening portions
321a, 321b, fabrics are formed into denser fabrics, compared to not only the peripheral
fabric main body portion 31 but also the weak tightening portions 322a, 322b. Moreover,
the chain structures are strongly apt to prevent the extension (reduce the degree
of elongation) in the warp direction of the fabric (knitting direction, which is the
direction of the arrow S), compared to the other structures. Therefore, combined with
the fact that the fabrics are formed densely, the strong tightening portions 321a,
321b can generate a strong tightening force.
[0030] Although not illustrated in Fig. 7, after forming the structures based on the chain
structures knitted into the strong tightening portions 321a, 321b, the yarn Y3 and
yarn Y4 are knitted into the weak tightening portions 322a, 322b, in the form of the
insertion structures similar to those formed in the range A1. Thereafter, courses
subsequent to A2 continue in the form of the chain structures knitted into the part
configured by the strong tightening portions 321a, 321b shown at the top of Fig. 3,
and finally the courses end up with the insertion structures knitted into the part
configured by short weak tightening portions 322a, 322b. As shown in Fig. 7, the yarn
Y3 and yarn Y4 are substantially symmetry with respect to a line. Although Fig. 7
illustrates only one of each yarns Y3 and Y4 and a part of each of the ranges A1,
A2 and A3, the same shapes as those of the tightening portions 32a, 32b shown in Fig.
3 are formed by drawing, in Fig. 7, all of the yarns Y3 and Y4, which are knitted
into the tightening portions 32a and 32b respectively, throughout the whole ranges.
[0031] Here, the insertion structures formed in the range A1 and the like are not limited
to the insertion structure of "1, 1/0, 0//" where a yarn moves between only two adjacent
needle space portions alternately as shown in Fig. 7, and thus may be the insertion
structure of "2, 2/0, 0//" shown by a yarn Y5, for example, or may be the insertion
structures shown by a yarn Y6 and a yarn Y7, as shown in Fig. 8. Increasing the swing
width of the inserted yarns in the horizontal direction (course direction) thereof
increases the quantity of yarns used and the tightening force of the weak tightening
portions 322a, 322b to be formed. In addition, as shown with a yarn Y8, appropriate
looping structures may be incorporated in accordance with the insertion structures.
In this case, the larger the proportion of the looping structures, the larger the
quantity of yarns used and the greater the tightening force of the weak tightening
portions 322a, 322b to be formed. However, the proportion of the looping structures
of the weak tightening portions 322a, 322b is smaller than the looping structures
included in the strong tightening forces 321a, 321b formed in the same belt, and the
tightening force of the weak tightening portions 322a, 322b is relatively weaker than
that of the strong tightening portions 3 21 a, 321b.
[0032] Moreover, the looping structures formed in the ranges A2, A3 and the like may not
necessarily be based on the chain structures shown in Fig. 7, but also may be based
on the 1/1 tricot structure shown with a yarn Y9 in Fig. 9 or the structure having
a combination of an open stitch and a closed stitch, as shown with a yarn Y10. When
not based on the chain structure, the effect of reducing the degree of elongation
of the fabric in the stitching direction becomes low, but the tightening force can
be adjusted accordingly. Moreover, the insertion structures may be combined based
on the looping structures as shown with yarns Y11, Y12. In this case, the larger the
proportion of the insertion structures, the lower the quantity of yarns used and the
weaker the tightening force. However, the proportion of the insertion structures of
the strong tightening portions 321a, 321b is lower than that of the weak tightening
portions 322a, 322b formed in the same belt, and the tightening force of the strong
tightening portions 321, 321b is relatively stronger than that of the weak tightening
portions 322a, 322b.
[0033] It should be noted that, regarding the amount of yarns used, the above has described
the simple situation where the amount of yarns to be supplied is controlled according
to the structure type only, but the structure type does not always determine the amount
of yarns used, or the tightening force is not always determined from the amount yarns
used. For example, even the insertion structure of "1, 1/0, 0//" in which the swing
width is small can adjust the amount of yarns to be supplied to be larger than that
of an insertion structure having a larger swing width. However, the increase of the
amount of yarns to be supplied does not necessarily lead to the increase of the tightening
force.
[0034] As described above, devising the structures of the weak tightening portions 322a,
322b and the structures of the strong tightening portions 321a, 321b can provide appropriate
tightening force to these tightening portions. Therefore, the difference in tightening
force between the strong tightening portions 322a, 322b and the fabric main body portion
31 and the difference in tightening force between the strong tightening portions 322a,
322b and the weak tightening portions 321a, 321b can be designed appropriately. Moreover,
the tightening force of the strong tightening portions 322a, 322b can be changed in
a multistage manner in the knitting direction and, similarly, the tightening force
of the weak tightening portions 321a, 321b can be changed in a multistage manner in
the knitting direction.
[0035] Measurement of the wearing pressure was performed on the girdle 1 of the present
embodiment that is created by the ground structures shown in Fig. 5 and Fig. 6 and
the yarn structures for reinforcing the tightening force as shown in Fig. 7, and as
a result the wearing pressure of the area where the strong tightening portions 321a,
321b are attached to a front thigh was 36 gf/cm2, and the wearing pressure of the
area where the fabric main body portion 31 without the tightening portions 32a, 32b
is attached to a back thigh was 24.4 gf/cm2, hence preferred wearing pressures and
a wearing pressure difference were realized. That is, no significant effect is anticipated
on the front thigh when the wearing pressure of the strong tightening portions 321a,
321b is low, but the wearer feels tightness when the wearing pressure of the strong
tightening portions 321a, 321b is high. Moreover, in order for the strong tightening
portions 321a, 321b to exert the effect thereof, it is desired that the wearing pressure
of the strong tightening portions 321a, 321b and the wearing pressure of the section
that does not form the tightening portions differ from each other by at least 10 gf/cm2.
Note that the wearing pressures were measured with a contact pressure measuring instrument
manufactured by AMI Co., Ltd. (Airpack type. The specifications: table type: AMI 3037-20;
sensor section: 20 mm diameter; maximum measured value: approximately 15000 Pa; guide
tube: 1.5 m), by putting the girdle 1 on a dummy (made of FRP). Regarding the waist
of the dummy, the length therefrom to the floor is 553 mm, the peripheral diameter
is 650 mm, the lateral diameter is 230 mm, and the thickness is 165 mm. Regarding
the hip of the dummy, the length therefrom to the floor is 385 mm, the peripheral
diameter is 895 mm, the lateral diameter is 320 mm, and the thickness is 215 mm. Regarding
a groin of the dummy, the length therefrom to the floor is 285 mm, the peripheral
diameter is 520 mm, the lateral diameter is 150 mm, and the thickness is 170 mm. Regarding
the section where the interspinal point of the dummy is located, the length therefrom
to the floor is 435 mm, the peripheral diameter is 845 mm, the lateral diameter is
305 mm, and the thickness is 202 mm.
[0036] As described above, in the girdle 1 of the present embodiment the yarn Y3 and the
yarn Y4 for reinforcing the tightening force are knitted continuously into the common
ground structures in the belt-like tightening portions 32a, 32b, and the strong tightening
portions 321a, 321b are formed mainly by the looping structures, while the weak tightening
portions 322a, 322b are formed mainly by the insertion structures. Therefore, the
strong tightening portions 321a, 321b are formed into a desired shape in an appropriate
position of the knitted fabric, and a sufficient difference in the tightening force
between the strong tightening portions 321a, 321b and the fabric main body portion
31 except the strong tightening portion and also between the strong tightening portions
321a, 321b and the weak tightening portions 322a, 322b can be obtained.
[0037] Furthermore, when the structures of the yarns for reinforcing the tightening force
of the strong tightening portions 321a, 321b are based on the chain structure, the
chain structure is strongly apt to prevent the extension (reduce the degree of elongation)
in the warp direction of the fabric. Therefore, combined with the fact that the fabrics
are formed densely, the strong tightening portions 321a, 321b can generate a strong
tightening force. Moreover, the strong tightening portions 321a, 321b are formed into
the shape of an X having the part inclined in the longitudinal directions of the weak
tightening portions 322a, 322b. Therefore, compared to a case where the strong tightening
portions 321a, 321b are in the form of strait lines extending in the same circumference,
the two strong tightening portions 321a, 321b concentrate on the central parts of
the thighs of the wearer without compressing the thighs in the form of a ring, and
thereby a tightening force can be dispersed in horizontal and vertical directions.
In addition, the tightening force can be set to a predetermined amount by changing
the structures of the yarns Y3 and Y4 for reinforcing the tightening force of the
strong tightening portions 321a, 321b, which are based on the chain structure, to
the other structure or by combining the structures of the yarns Y3 and Y4 with the
insertion structures. Similarly, regarding the structures of the yarns Y3 and Y4 for
reinforcing the tightening force of the weak tightening portions 322a, 322b, the tightening
force can be set to a predetermined amount by increasing the swing width in the horizontal
direction from the insertion structures of "1, 1/0, 0//" or by combining the structures
of the yarns Y3 and Y4 with the insertion structures. Moreover, the tightening force
of the strong tightening portions 322a, 322b can be changed in a multistage manner
in the knitting direction and, similarly, the tightening force of the weak tightening
portions 321a, 321b can be changed in a multistage manner in the knitting direction,
by changing the knit structures formed by the yarns Y3 and Y4 for reinforcing the
tightening force of the tightening portions 32a, 32b.
[0038] The garment of the present invention that is attached tightly to a body is not limited
to the one described above. For example, the belt-like tightening portions 32a, 32b
may be formed into various shapes by the strong tightening portions 321a, 321b and
weak tightening portions 322a, 322b shown in (A) through (H) of Fig. 10. As shown
in (F), when the strong tightening portions 321a, 321b are formed linearly along with
the weak tightening portions 322a, 322b, a thigh can be tightened strongly in the
form of a ring. Conversely, when avoiding a ring-like tightness, the strong tightening
portions 321a, 321b are formed into an appropriate shape so as to have the parts inclined
in the longitudinal directions of the weak tightening portions 322a, 322b as shown
in the diagrams other than (F) of Fig. 10, so that desired direction and position
of the tightening force of the strong tightening portions 321a, 321b can be obtained.
Furthermore, a single belt-like tightening portion 32a may be obtained without combining
the two belt-like tightening portions 32a, 32b, as shown in an example in (H).
[0039] Also, the place for forming the tightening portions 32a, 32b is not limited to the
front thigh of the girdle 1. Fig. 11 is a perspective view showing an example in which
the present invention is applied to other section of the girdle 1, wherein the girdle
1 is viewed from the front. One tightening portion 32a is formed in the abdominal
cloth 4. Especially by forming the strong tightening portion 321a in the center of
the abdomen, a tightening force can be added to the abdomen of the wearer so as to
prevent the abdomen from bulging. Fig. 12 is a perspective view showing another example
of application of the present invention, wherein the girdle 1 is viewed from behind.
The hip of the wearer can be lifted up by forming the strong tightening portions 321a,
321b of the tightening portions 32a, 32b in a section between the lower part of the
bulge of the hip of the wearer and a side part of the hip, whereby the body shape
of the wearer can be compensated. Fig. 13 is a perspective view showing yet another
example of application of the present invention, wherein a short girdle 5 is viewed
from behind. The tightening portion is formed by one belt-like tightening portion
32a. The strong tightening portion 321a is formed in a section corresponding to the
lower part of the bulge of the hip of the wearer, whereby the hip of the wearer can
be lifted up to compensate the body shape of the wearer. Fig. 14 is a perspective
view similarly showing the back of the short girdle 5. The strong tightening portion
321a is similarly formed in the section corresponding to the lower part of the bulge
of the hip of the wearer, but the strong tightening portion 321a and the weak tightening
portion 322a are formed alternately in a multistage manner, and the length in a belt
direction of the strong tightening portion 321a is increased at a lower part of the
center of the hip to adjust the strength of the tightening force in the belt direction
in a multistage manner. Accordingly, the tightening force can be applied gradually
from the section requiring a strong tightening force toward a section that does not
require a strong tightening force. Furthermore, although not shown, the strong tightening
portion can be formed in a section between a side portion and a back portion of a
brassiere, or a side portion and a rear portion of a body suit.
[0040] Moreover, in the garments shown in Fig. 11 through Fig. 14 and a brassiere or a body
suit that is not shown, the shapes of the tightening portions are not limited, hence
the belt-like weak tightening portions and strong tightening portions may be formed
in various shapes as shown in the modifications shown in Fig. 10.
[0041] The above has described the case where the ground structures of the fabric main body
portion 31 are identical to each other, but the ground structures configuring the
fabric main body portion 31 may vary depending on the places thereof in the fabric
main body portion 31. Examples of application of such ground structures are described
with reference to Fig. 15 through Fig. 17. Fig. 15 is a view in which the girdle 1
is viewed edge-on. The fabric main body portion 31 forming the body 2 is sectioned
into knitted fabric parts that are formed respectively by two types of ground structures
having different tightening forces. A knitted fabric part 31a positioned in the center
with respect to the horizontal direction is knitted by a ground structure having a
relatively strong tightening force, and knitted fabric parts 31b positioned on both
sides of the knitted fabric part 31 a are knitted respectively by weak ground structures
having a relatively weak tightening force. The weak tightening portion 322a of the
single belt-like tightening portion 32a are formed at substantially right angles to
borderlines 35 of the knitted fabric parts 31 a, 31b. The weak tightening portions
322a are formed on two sides, the right and left sides, with a step formed therein
so as to overlap with the knitted fabric part 31 b having a relatively weak tightening
force, and the strong tightening portion 321 a is formed between the weak tightening
portions 322a so as to overlap with the knitted fabric part 31 a having a relatively
strong tightening force. The strong tightening portion 321a is inclined such that
the front side thereof is positioned upward.
[0042] Here, each of the weak tightening portions 322a and the respective borderlines 35
are formed at substantially right angles to each other, but may form a different crossing
angle, hence the belt-like tightening portion 32a constituted by the strong tightening
portion 321a and the weak tightening portions 322a may intersect with the borderlines
35. Moreover, the position of the knitted fabric part 31b with a relatively weak tightening
force overlaps with the positions of the weak tightening portions 322a, and the position
of the knitted fabric part 31a with a relatively strong tightening force overlaps
with the positions of the strong tightening portions 321a, but these positions may
not be overlapped and the knitted fabric part 31a with a strong tightening force may
overlap with at least a part of the strong tightening portion 321a. Then, the overlapped
parts are provided with a stronger tightening force due to the strong tightening force
of the ground structures of the knitted fabric and the overlapping strong tightening
portion 321a of the tightening portion 32a.
[0043] The tightening portion 32a is positioned on an outer periphery of an upper part of
a thigh of the wearer, and the strong tightening portion 321a of the tightening portion
32a is positioned in each side portion of the hip. Therefore, the section between
the upper part of the thigh and the lower part of the hip of the wearer is tightened,
and particularly the strong tightening portion 321 a prevents the both sides of the
hip from bulging, whereby the body shape is fixed. Moreover, because not only the
strong tightening portion 321a of the side portion of the hip but also the knitted
fabrics 31a positioned above and below the strong tightening portion 321a are formed
to have a stronger tightening force compared to the other knitted fabric parts 31b,
the entire side portion of the hip can be tightened. Also, because the strong tightening
portion 321a is inclined upward or downward and has the part inclined in the longitudinal
direction of the weak tightening portion 322a, the entire tightening portion 32a is
prevented from being formed into a ring of the same circumference, and particularly
the tightness generated by the strong tightening portion 321a can be alleviated.
[0044] Next, the fabric 3 configuring the body 2 of the girdle 1 is described with reference
to Fig. 16. As with Fig. 2, Fig. 16 is a schematic diagram showing one unit of fabric
3 for creating the body 2 on the left side of the girdle 1. The fabric 3 is a warp
knitted fabric knitted by yarns supplied in the direction shown by the arrow S, and
has the one belt-like tightening portions 32a formed at a part of the fabric main
body portion 31 configured by a ground structure. The tightening portion 32a is configured
by the strong tightening portion 321a and the weak tightening portion 322a as described
with reference to Fig. 15. Furthermore, the hems 33 for preventing raveling of the
yarns are formed at upper and lower edges. As with the cases shown in Fig. 1 through
Fig. 3, in order to produce the girdle 1, the left body 2 is cut from the fabric shown
in Fig. 16, similarly the right body 2 is cut from a fabric symmetric with the one
shown in Fig. 16, and these bodies 2, an abdominal cloth 4 and a crotch are stitched
together, and eight units of the fabric 3 are knitted integrally by the warp-knitting
machine.
[0045] The major difference between Fig. 16 and each of Fig. 1 through Fig. 3 is that in
Fig. 16 the ground structure of the range between the right end of the fabric 3 and
the borderline 35 is knitted by a 1/2 tricot structure shown in, for example, the
left side of Fig. 17, and that the subsequent range up to the left borderline 35 is
knitted by a 1/3 tricot structure shown on the right side of Fig. 17. Compared to
the 1/2 tricot structure, the 1/3 tricot structure has a larger amount of yarns used
and a relatively stronger tightening force. Note that, as with the cases shown in
Fig. 1 through Fig. 7, the yarns for reinforcing the tightening force are knitted
into the fabric 3 so that the tightening portion 31 is formed along with the ground
structures.
[0046] Moreover, as the ground structures with different tightening forces, not only such
1/2 tricot structure and 1/3 tricot structure but also appropriate structures can
be adopted in which, for example, a net structure (mesh structure) having low-density
stitches is formed as the weak knitted fabric part 31 b having a relatively weak tightening
force, and various satin structures having denser stitches are formed as the strong
knitted fabric part 31a having a relatively strong tightening force. Furthermore,
there may be three or more types of such different ground structures, and each of
the knitted fabric portions may be sectioned into four or more sections or two sections.
In addition, the knitted structure of the tightening portion 32a may be configured
in various ways as described with reference to Fig. 8 and Fig. 9, and various shapes
as illustrated in Fig. 10 can be adopted as the shape of the tightening portion.
[0047] In addition, regarding Fig. 15, Fig. 16 and the modifications thereof, because all
of the borderlines 35 of the knitted fabrics are formed so as to intersect with the
belt-like tightening portion 32a, the tightening portion 32a configures the ground
structure that is common in the knitted fabric parts 31a, 31 b of the fabric main
body portion 31 that are adjacent to the tightening portion 32a and all adjacent portions.
However, for example, the ground structure of the tightening portion 32a including
the strong tightening portion 321a and the weak tightening portion 322a can be configured
to be the same as the ground structure of the knitted fabric part 31a having a strong
tightening force. In this case, of the tightening portion 32a, only a section adjacent
to the knitted fabric part 31a with a strong tightening force is formed into the ground
structure that is identical to the ground structure of the fabric main body portion
31, and the ground structures of the knitted fabric part 31b with a weak tightening
force and a part adjacent thereto become different.
