Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garment having a portion for covering a body in a tubular shape, and a garment using the garment.

[0002]

2. Description of the Related Art Conventionally, the waist size of clothes is fixed and cannot be freely adjusted.
Therefore, if the body shape changes and the waist size or the like changes, it becomes impossible to wear it. Therefore, conventionally, the dimensions of pants and the like have been modified. Also, there has been proposed a free-size garment in which an elastic material such as rubber is put on the entire circumference of the waist to increase the size of the fabric and make the waist stretchable.

In order to make the size of the waist expandable and contractable, there has been proposed a configuration in which a part of the fabric of the waist has a double structure and an elastic material such as rubber is sewn into the double structure (see, for example, Japanese Patent Application Laid-Open No. H8-208). No. 113805).

[0004]

However, the work of resizing involves the troublesome work of unsewing the sewn cloth, performing sewing, and then performing sewing with the corrected size. There was a problem. When unsealing, scissors must not be cut, so not only is it necessary to use nerves, but also in the case of stitching to increase the waist size, the needle holes and folding lines existing at the previous sewing position It is also necessary to take measures to make the inconspicuousness. Further, in the case of sewing, there is a case where a necessary margin does not exist in the original cloth, and it is not always possible to resize to a required size. In addition, such work requires complicated labor and skill, but it is difficult to obtain a price corresponding to the work.

[0005] In addition, in a free-size garment in which an elastic material such as rubber is put around the waist and the cloth is large, the cloth is large, so that when a person with a narrow waist wears the cloth, the cloth is wrinkled. And there was a problem that the appearance was bad. On the other hand, with a waist with a double structure,
The rubber provided here allows the size to expand and contract to some extent, but the double-structured part is sewn to the lower fabric, and when the double-structured part extends, It was pointed out that the fabric was pulled and wrinkled.

The present invention has been made to solve the above problems and proposes a suitable structure for expanding and contracting the size of clothes. Using this structure, the present invention proposes a garment that achieves both appearance and comfort when worn. The purpose is.

[0007]

Means for Solving the Problems and Actions / Effects The garment size expansion / contraction structure of the present invention is a garment size expansion / contraction structure having a portion for covering the body in a cylindrical shape, and comprises a stretchable band-like elastic material. Two bag portions in which the elastic material is stored are formed, and both ends of the elastic material are sewn to the bag portion, respectively, and the elastic portions are sewn to the clothing to cover the body in a tubular shape. A cloth forming at least a part thereof, and a covering addressing cloth provided at a position covering a portion of the two bag portions accommodating the elastic material in which the fore-edges face each other, wherein the cloth is formed on the cloth. At a position corresponding to the edge of the sewn bag portion, a cut is formed over a predetermined distance in a direction intersecting the direction of expansion and contraction of the elastic material, and the covering cloth covers the cut, and the cut is formed. Outside of
The gist is a structure sewn on the cloth.

[0008] The garment of the present invention is characterized in that such a size elastic structure is provided in at least one place.
As such clothes, pants, culottes, pantalons, skirts, dresses, and the like having cloth covering at least the waist of the body can be considered.
Of course, it is also possible to apply to places other than the waist.

In the garment of the present invention, the size of the garment can be expanded and contracted, and the garment using the expanded and contracted structure can be formed with two bags for accommodating an elastic band-shaped elastic material. Each has a sewn elastic part, and the elastic part of the garment expands and contracts by the elastic force of this elastic material. Therefore, there is no need to make repairs to adjust the dimensions of the clothes when purchasing the clothes or when the wearer's body shape changes after the purchase. Further, it is possible to easily perform daily operations such as sitting, standing, running, and the like.

[0010] Further, the elastic portion including the bag portion is sewn,
The cloth that forms at least a part of the clothing that covers the body in a cylindrical shape has a predetermined distance in a direction that intersects with the direction of expansion and contraction of the elastic material at a position corresponding to the edge of the bag sewn on the cloth. A notch is formed. Therefore,
The expansion and contraction of the cloth due to the expansion and contraction of the elastic material is absorbed by the cuts formed in the cloth, and the expansion and contraction of the elastic material does not affect the expansion and contraction of the cloth. Therefore, the elastic material does not wrinkle over a wide area due to the expansion and contraction of the elastic material, and the silhouette of the clothes can be kept beautiful regardless of whether it is worn or not.

[0011] Further, a covering patch cloth is provided at a position where the front edge of the two bag sections accommodating the elastic material is opposed to each other, and the covering patch cloth covers the cuts formed in the fabric, Outside of this cut is sewn to the fabric. Accordingly, the wrinkles and the elastic material absorbed by the cuts formed in the fabric are not visible from the outside, so that the same aesthetic appearance as that of ordinary trousers having no elastic portion due to the elastic material can be secured. Further, since the bag portion, the cloth, and the like are hardly rubbed with the expansion and contraction of the elastic material, the cloth is not consumed by friction due to the expansion and contraction of the clothes.

Further, the bag portion may be provided along the mounting portion of the belt, and the cloth for covering may be used also as the belt passing. In this case, there is no unnaturalness in the design because the cloth for covering also serves as the belt loop. At the end on the side sewn to the fabric,
The width can be shaped to gradually decrease toward the tip.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION In order to further clarify the structure and operation of the present invention described above, an embodiment of a garment size expansion / contraction structure of the present invention will be described below based on examples. FIG. 1 is an explanatory view showing an elevational surface of a rear waist portion of the pants 10 according to the first embodiment of the present invention. The trousers 10 are substantially the same in structure as conventional trousers except for the elastic structure described later, and the outer shape of the trousers 10 is sewn to the cloth forming the body part with the thread. Is formed. FIG. 1 shows a state in which the waistband body 12 on the rear side of the pants 10 and the back body 14 have already been sewn with a thread. Back body 14 is pocket 1
The back body left 14a and the back body right 14b provided with the body 8 are sewn together by body sutures 22.

The trousers 10 are provided with a belt loop 16 and a loop 20 made of the same fabric as the trousers 10 on the back side of the waist. One end of the belt loop 16 is sewn to the back body 14 and the other end is sewn to the waistband body 12, and the loop 20 is sewn to the back body 14 at one end exposed to the outside of the pants by a loop sewing thread 32. , And is sewn to the other end of the loop 20 existing inside the pants through the sewn portion to the back body 14.

The loop 20 not only plays a role as a belt loop, but also plays a role of hiding the elastic structure, which is a characteristic part of the pants 10 of this embodiment, from being seen from the outside. Therefore, if this loop 20 is removed, the pants 1
The 0 stretch structure is exposed. FIG. 2 shows this exposed state. As shown in FIG.
Is divided into two parts by a line obtained by extending a line along which the body suture 22 sew the left and right back body 14 toward the waistband body 12 (hereinafter referred to as a body suture locus line). Both ends of the separated waistband body 12 have a predetermined length of rubber 24.
Are connected using The rubber 24 plays a role in expanding and contracting the waist portion of the pants 10. Details of this expansion and contraction mode will be described later.

The rubber 24 has a left end 24a and a right end 24a which are separated from the cut end of the waistband body 12 in the direction of the belt loop 16 so that a certain length of elongation is secured.
In FIG. 2 (b), it is sewn on the inner side of the waistband body 12 by a rubber sewing thread 24n. Thus, the waistband body 12 is
Together with the rubber 24, the waist of the pants 10 is constituted.

As shown in FIG. 2, a body notch 26 is formed on the rear body 14 at a position along a body stitching trajectory line. The process of forming the body notch 26 will be described with reference to FIG. First, back body left 14a and back body right 14
b is sewn to the waistband body 12. Pants 1
FIG. 3 (A) shows a view from the back ground of No. 0. Trousers 1
The waist band body 12 serving as the waist portion of the “0” has a folded portion 12a.
3A is formed by being folded back along the alternate long and short dash line in FIG. 3A to the back side of the pants 10, but has not yet been folded before the body notch 26 is formed. A seam allowance 15 for sewing the rear body left 14a and the rear body right 14b is provided at an end of the rear body left 14a and the rear body right 14b. This seam allowance is indicated by a double dashed line.

Next, as shown in FIG.
The back body left 14a and the back body right 14b are sewn together with the body suture 22 while leaving the seam allowance 15 behind the zero. The back body left 14a and the back body right 14b are
The part is sewn up to a point Y before reaching the part, and is not sewn thereafter. The dimension X shown in the figure indicates the shortest distance from the terminal point Y where the back body left 14a and the back body right 14b are sewn to the sewn portion between the back body 14 and the waistband body 12, and in this embodiment, This value is set to 20 mm to 30 mm. The dimension X may be determined according to the size of the pants, the properties of the cloth, or the range of expansion and contraction adjustment, and the like.
What is necessary is just to determine suitably between several mm and about 100 mm.

Next, as shown in FIG. 3 (C), the left and right seam allowances 15 of the portions not sewn by the body sutures 22 are respectively opened outward to expand the width of the seam allowance 15, and this expanded seam allowance is obtained. Stitch 2 at the bent part of the seam allowance
Apply 3. As a result, a substantially V-shaped notch 25 is provided between the cloth for the back body left 14a and the cloth for the back body right 14b.
Is formed.

The size of opening the seam allowance 15 outward is arbitrary, but the seam allowance 15 is opened outward so that the maximum width of the notch 25 when the rubber 24 is extended is smaller than the width of the loop 20. Is desirable. If the original width of the seam allowance 15 is maintained without being opened at all, the notch 25
If the cloth is loose in the vicinity and the silhouette of the trousers cannot be maintained beautifully, but too wide, the maximum width of the notch 25 becomes larger than the width of the loop 20 and the rubber 24 becomes visible from the outside. The maximum width of the notch 25 may be appropriately determined from these points.

In the expanded seam allowance, FIG.
The hatched portion in (C) is cut off. this is,
This is because when the rubber 24 is sewn to the waistband body 12 and the folded back portion 12a is turned back to the back side of the pants 10, the burden on the expansion and contraction of the rubber 24 due to the thickness of the waistband body 12 is prevented. . By cutting off the hatched portions in the figure, the waistband body 12 does not become excessively thick. The area to be cut off may be determined as appropriate depending on the thickness of the cloth of the pants 10 and the presence or absence of stiffness.

Next, as shown in FIG.
A predetermined length of rubber 24 is sewn to the second folded portion 12a. In this embodiment, the length is 100 mm to 120 mm.
Then, in order to use the rubber 24 having a width smaller than the width of the folded portion 12a by about 5 mm and to expand and contract the rubber 24 equally to the left and right, the position of the rubber 24 is adjusted so that the center of the rubber 24 is on the body sewing locus line. I have decided. At this position, a rubber left end 24a and a rubber right end 2
4b is sewn twice to the folded-back portion 12a to secure elasticity of the rubber in the left-right direction of the waist. Of course, the present invention is not limited to rubber, and other elastic materials, for example, synthetic resin or cloth material having a certain elasticity may be used. Further, the length, arrangement, sewing position and sewing method of the elastic material such as rubber can be appropriately changed according to the elastic force of the elastic material used and the width of the cutout 25.

After the rubber 24 is sewn to the folded portion 12a, the folded portion 12a is folded back along the chain line shown in FIG. Is sewn on the line where is sewn. As a result, as shown in FIG.
A body notch 26 is formed in a space surrounded by the body 4 and the back body 14. Since the folded portion 12a is folded back toward the back side of the pants 10 to form a bag portion, the sewing thread 2 in which the rubber 24 stored in the bag portion is sewn to the folded portion 12a.
4n is not visible from the outside of the pants 10.

The process of forming the body notch 26 has been described above. However, this process is merely an example, and the body notch 26 can be formed by a process different from this process. For example, from the state in which the back body left 14a and the back body right 14b of FIG. 3A are sewn to the waistband body 12, first, the upper right part of the back body left 14a and the back body right 14b. Is cut diagonally from the waistband body 12 to the back body 14, and the cloth on the cut surface is several meters.
Fold back about m and stitch the fold back, then sew the back body left 14a and the back body right 14b together, and the clothing for the back body left 14a and the back body right 14b
A substantially V-shaped notch 25 surrounded by a cut surface with stitches may be formed between the garment and the clothing. By doing so, the notch 25 and the body notch 26 can be formed with more accurate dimensions.

In this embodiment, the notch 25 and the body notch 26 are linearly formed into a substantially inverted triangular shape. However, the present invention is not limited to such a shape, and the notch continuous from the waistband body 12 to the back body 14 is not limited thereto. If a portion is provided, it can be formed by cutting out in a curved shape.

Next, the body notch 26 formed in the back body 14 and the loop 20 provided in the exposed portion of the rubber 24 will be described. FIG. 4A is a developed view of the loop 20 used in the present embodiment. Loop 20 is for pants 1
It consists of the same fabric as the front fabric of No. 0. The loop 20 includes an outer portion 20a exposed on the front side of the pants 10 and an inner portion 20b hidden on the back side of the pants 10. Outer part 2
0a and the inner part 20b have a substantially equal length h, and the length h is from the end point Y where the back body left 14a and the back body right 14b shown in FIG. The length is set to be several mm longer than the vertical distance to the upper end of the body 12.

The width w of the outer portion 20a and the inner portion 20b is set to be larger than the width of the exposed portion of the rubber 24 and the width of the body notch 26 when the rubber 24 is stretched most. The width w of the outer portion 20a gradually decreases while drawing a gentle curve toward the end of the loop 20. Since the width of the other belt loops 16 is relatively small, the width of the lower end of the loop 20 is reduced, so that the overall design of the pants 10 is well balanced. Further, since the loop 20 has a shape in which the width of the lower end portion is gradually reduced, when the trousers 10 are actually worn through the belt, the lower end portion does not roll up. The shape of the outer portion 20a is not limited to this, and may be a simple rectangular shape that does not take the design into consideration, such as the loop 38 shown in FIG. 4B, or another special design. Good. Further, since the width w of the loop 20 is relatively wide, it is possible to apply a pattern, a mark, or the like to the surface of the loop 20 by embroidery, transfer, or the like.
This, coupled with the smooth outline of the loop 20,
The design of the loop 20 can be further improved.

Next, a method of attaching the loop 20 to the pants 10 will be described with reference to FIGS.
FIG. 5 shows the front side of the rear waist portion of the pants 10, and FIG. 6 shows the rear side thereof. The loop 20 includes a loop sewing thread 36, a loop suture thread 30, and a loop sewing thread 32.
Are attached to the pants 10. The loop sewing thread 36 connects the loop 20 and the rubber 24,
The loop suture 30 connects the outer portion 20 a and the inner portion 20 b of the loop 20, and the loop suture 32 connects the loop 20 and the back body 1.
4 are sutured. Hereinafter, description will be given according to the actual operation procedure.

First, the inner portion 20 b of the loop 20 is applied to the back of the waistband 12. At this time, the position where the inner part 20b is applied is a position where the outer part 20a and the inner part 20b that are folded in two cover the rubber 24 sewn to the waistband body 12. Next, the inner portion 20b is sewn to the rubber 24 by the loop sewing thread 36. As a result, even when the rubber 24 is stretched, the loop 20 moves following the direction in which the rubber is stretched, so that the loop 20 does not independently shift back and forth and right and left. Therefore, the rubber 24 is always in the loop 20 even if the waist is twisted left or right or the like.
And the rubber 24 is not visible from the outside. Further, when the posture is returned to the original position, the left and right ends of the loop 20 do not get caught on the waistband body 12. Further, the rubber 24 and the inner portion 20b are sewn from the back side of the pants 10, and the loop sewing thread 36 is not visible from the outside, so that the appearance of the pants 10 is not spoiled.
In addition, since the outer portion 20a and the rubber 24 are not sewn together, the outer portion 20a can be used as a belt for the loop 20 without any problem.

Next, the outer portion 20a and the inner portion 20b are sewn together by the loop suture 30. The body notch 26 is provided on the back side of the loop 20 at the sewing position.
, The outer portion 20a and the inner portion 20b are directly sewn together. As a result, the independence of the loop 20 is ensured, and it is possible to prevent the loop 20 from being lifted or exposed by a small daily movement. In addition, the waistband body 1
Since the rubber 24 is sewn to the lower end position of the loop 2, it is difficult to see the rubber 24 from the left and right sides of the loop 20, and it is difficult to determine that the pants 10 use the rubber 24.

Finally, the lower end of the outer portion 20a and the lower end of the inner portion 20b are sewn to the back body 14 with a loop sewing thread 32. In the present embodiment, this sewing is realized by the same loop sewing thread 32. That is, the loop sewing thread 32 includes the outer portion 20a, the back body 14, the seam allowance 1
5, penetrates the inner part 20b.

The manner in which the trousers 10 of the present embodiment having the above-described structure actually expands and contracts the waist will be described with reference to FIG. FIG. 7 shows the operation of the telescopic portion hidden by the loop 20 before and after wearing the pants 10.

FIG. 7A shows a state in which the waist is most contracted, that is, a state in which the waist is not worn. In this state, the rubber 24 shrinks, so that both edges of the waistband body 12 are
4 and a back body left 14a and a back body right 14b sewn to the waistband body 12 accordingly.
Has been pulled as well. As a result, wrinkles usually occur in the back body 14 below the rubber 24. However, as shown in FIG. 7A, the shrink width of the back body 14 is absorbed by the body notch 26, There is almost no wrinkle on the rear body 14 below the rubber 24 in a range visible from the outside.

When the trousers 10 are worn and the waist is in the most stretched state, the stretchable portion hidden by the loop 20 is in a state as shown in FIG. 7B. That is, when the waistband body 12 is pulled in accordance with the body shape of the wearer by the action of hooking the waist portion on the front side of the pants, the rubber 24 sewn to the waistband body 12 extends right and left. Along with this, the back body left 14a and the back body right 14b sewn to the waistband body 12 are also pulled leftward and rightward, respectively. At this time, the width of extension of the rear body 14 is absorbed by the expansion of the width of the body notch 26. Therefore, due to the pulling force of the waist portion, no excessive force is applied to the rear body 14 of the pants 10 to cause the wrinkles to be pulled or torn in some cases. In addition, back body left 1
The body suture 22 that stitches the back body 4a and the back body right 14b does not fray.

As described above, since the loop 20 has a width larger than the width of the exposed portion of the rubber 24 and the width of the body notch 26 when the rubber 24 is stretched most,
Even if the waist of the pants 10 is fully extended, the rubber 2
4 and the body notch 26 are not visible from the outside. When the pants 10 are taken off, the elastic portion returns to the state shown in FIG. 7A, and a beautiful trouser silhouette without wrinkles below the elastic portion is maintained.

The trousers 10 according to the first embodiment to which the waist elastic structure such as trousers of the present invention is applied have been described. Next, a pants 40 according to a second embodiment will be described with reference to FIGS. FIG. 8 is an explanatory view showing an elevational surface of a waist portion on the left lateral side of the pants 40 according to the second embodiment of the present invention. The trousers 40 are provided with a loop 50 made of the same fabric as the trousers 40 on the left side and the right side (not shown) of the waist, and the waist is stretched using a rubber 54 in a portion covered by the loop 50. It has a part.

The loop 50 is sewn to the front body 42 by a loop sewing thread 60. When the loop 50 is removed, the elastic structure of the pants 40 is exposed. FIG. 9 shows this exposed state. As shown in FIG. 9, the waistband body 12 of the pants 40 has a line obtained by extending a line along which the body suture 52 sews the front body 42 and the back body 14 toward the waistband body 12 (hereinafter referred to as a body suture locus). (Referred to as a line). This separated waistband body 12
Are connected by rubber 54 of a predetermined length. The rubber 54 plays a role in expanding and contracting the waist portion of the pants 40. Details of the expansion and contraction will be described later.

The right end 54b of the rubber 54 has a waistband 1 so that a certain length of extension is secured in the rearward direction of the pants.
At a position spaced apart from the right cut end of No. 2 in the direction of the belt loop 16 on the rear side, the waistband body 12 is
Sewn inside. On the other hand, the left end 54a of the rubber 54 is sewn to the inside of the waistband body 12 by a rubber sewing thread 54n at a position near the left cut end of the waistband body 12. Thus, the waistband body 12 is
Together with the waist of the pants 40.

On the front body 42 and the back body 14, a body notch 56 is formed at a position of the body suture trajectory line. The process of forming the body notch 56 is substantially the same as that of the first embodiment. That is, after the front body 42 and the back body 14 are sewn to the waistband body 12, respectively, the front body 42 and the back body 14 are sewn to the point before reaching the waistband body 12 by the body sutures 52. Next, from the back side of the pants 40, the width of the seam allowance is expanded by outwardly opening the left and right seam allowances of the portion not sewn by the body sutures 52, and the width of the seam allowance for the front body 42 and the back body 14 are increased. A substantially V-shaped notch is formed between the garment and the fabric.

Next, a predetermined length of rubber 54 is sewn to the folded portion of the waistband body 12. In this embodiment, in order to expand and contract the rubber 54 only in the rearward direction, the center of the rubber 54 is set to the right side of the body suture trajectory line, and the left end 54 a of the rubber 54 is located near the left end of the waistband body 12. The position of the rubber 54 is determined.

Next, the folded portion 1 on which the rubber 54 is sewn
The 2a is folded back toward the back side of the pants 40, and is sewn on the line where the front body 42 and the back body 14 and the waistband body 12 are already sewn. By doing so, the rubber 5
A body notch 56 is formed in a space surrounded by the front body 4, the front body 42, and the back body 14.

The loop 50 is obtained by changing the shape and the material of the loop 20 in the first embodiment, and the basic configuration and the method of attaching to the pants are substantially the same as those of the loop 20. That is, the inner portion of the loop 50 is applied to a position on the back side of the waistband body 12 where the outer portion and the inner portion folded in two cover the rubber 54 sewn to the waistband body 12.
Next, the loop inner portion is covered with rubber 54 by a loop sewing thread.
Then, the lower front side of the outer side portion of the loop and the lower front side of the inner side portion are sewn to the front body 42 by the loop sewing thread 60.

However, in the second embodiment, the loop 5
0 designates a body notch 56 between the outer portion and the inner portion of the loop 20.
Not directly stitched over. This is because, as shown in FIG. 8, the loop 50 is
2 is sewn to the lower end position, so that the loop 50
This is because the independence of the loop 50 is sufficiently ensured without sewing the outer portion and the inner portion of the loop 50, and the loop 50 does not float or bulge. Of course, similarly to the first embodiment, the outer portion and the inner portion of the loop 50 may be stitched together.

The operation of expanding and contracting the waist of the pants 40 according to the second embodiment having the above-described structure will be described. In the unworn state in which the waist portion has contracted most, the rubber 54 shrinks toward the front side of the trousers 40, so that the waistband body 12
Is pulled so as to approach the left edge of the waistband body 12, and accordingly, the back body 14 sewn to the waistband body 12 is also pulled in the same direction. As a result, wrinkles usually occur in the back body 14 below the rubber 54, but the shrink width of the back body 14 is reduced by the body notch 5
6, almost no wrinkles are formed on the rear body 14 in a range visible from the outside below the rubber 54.

When the pants 40 are worn and a hook is applied to the waist portion in front of the pants, the waistband 12
However, the rubber 54 sewn on the left cut end side of the waistband body 12 is also pulled according to the body shape of the wearer.
It is pulled to the front of zero. The left end 54a of the rubber 54 is sewn near the left cut end of the waistband body 12, and
It has almost no frontal extension length of zero. Accordingly, the pulling force of the waistband body 12 toward the front side is not absorbed by the extension of the rubber 54, and the rubber 54 itself tries to move to the front side of the pants 40 as it is. However, when the waistband body 12 moved forward and came into close contact with the wearer's waist,
A force acts to return the right cut end side of the waistband body 12 to the rear side of the pants 40. Accordingly, the rubber 54 sewn near the right edge of the waistband body 12 extends in the rearward direction of the pants 40 due to this force, and accordingly, the back body 14 sewn to the waistband body 12 also moves rightward. Pulled. At this time, the extension width of the back body 14 is absorbed by the expansion of the width of the body notch 56. Therefore, due to the pulling force of the waist portion, an unreasonable force is applied to the rear body 14 of the trousers 40 to prevent the wrinkles from being pulled or torn in some cases. Further, the body suture 52 that stitches the front body 42 and the back body 14 does not fray.

Further, since the loop 50 has a width larger than the width of the exposed portion of the rubber 54 and the width of the body cutout portion 56 when the rubber 54 is stretched most, the waist portion of the pants 40 is completely stretched. The rubber 54 and the body notch 5
6 is not visible from the outside. When the trousers 40 are taken off, the elastic part returns to its original state, and the beautiful trouser silhouette without wrinkles below the elastic part is maintained.

In the second embodiment, rubber 54 is sewn on both sides of the waist of the pants so as to extend and contract the waist only in the rear direction of the pants. Therefore, since the wrinkles do not locally form on the body below the waist elastic portion, the silhouette of the pants when not worn can be made closer to ordinary pants. In addition, rubber 5
Since the tightening of the waist by 4 is distributed on both the left and right sides, the feeling of pressure on the waist when wearing pants can be reduced.

In this embodiment, the waist portion is expanded and contracted only in the rear direction of the pants 40.
By changing the attachment position of the rubber 54 to the second member 2, it is also possible to adopt a configuration in which the rubber is expanded and contracted only in the front direction, or a configuration in which the rubber 54 is expanded and contracted in both the front and rear directions. In this way, by changing the direction of expansion and contraction, it is possible to provide pants corresponding to the use of the wearer. For example, in the case of work pants, since the pants tend to be bent forward, they can be configured to expand and contract in the rear direction of the pants.
On the other hand, in the case of trousers for people whose body shape in the front abdomen changes drastically, it expands and contracts in the front direction of the pants, or in the case of sports pants, expands and contracts in both the front and rear directions. It is also possible to configure the waist.

The pants to which the waist elastic structure of the present invention is applied have been described as the first and second embodiments. However, embodiments for carrying out the present invention are not limited to the above-described embodiments, and can be carried out in other forms. First, in the present embodiment, the pants with the belt passing are described as an example, but it goes without saying that the pants without the belt passing may be used. Further, in the present embodiment, the loop and rubber,
The outside and the inside of the loop and the loop and the back body are respectively joined by a thread, but may be joined by other joining means such as a button.

Further, in this embodiment, the position of the expansion / contraction portion is
It is formed above the stitched part of the body. This is because the body cutout can be easily formed by using the stitched portion, but, of course, the expansion and contraction portion may be provided at other positions.

In this embodiment, the case where the clothing size expansion / contraction structure is applied to the pants has been described. Of course, the expansion / contraction structure of the present invention can be applied to clothing other than the pants, for example, the waist portion of a skirt or the like. is there. Further, the elastic structure such as the waist of the present invention can be adopted as an elastic structure other than the waist part of the clothes. In particular, a sufficient effect can be obtained by applying the stretchable structure of the present invention to a part of clothes using fabric that is difficult to expand and contract, and is likely to expand and contract due to movement of the body. Applicable garments and their parts include, for example, suits, side portions and elbows of shirts, knees of pants, tight skirts and buttocks of dresses, and the like. In such a case, as a hidden material of the elastic part,
Appliques, decorative buckles, ribbons and the like may be used.

The embodiments of the present invention have been described above.
The present invention is not limited to such embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention.
