Furthermore, in order to solve the above-mentioned problems, it is also considered to provide elastic rubber in the waist. However, in this case, the size of the front and back parts of the covering elastic rubber must be longer than the elastic rubber by the amount that the elastic rubber stretches, and so-called wrinkles are formed on the front and back parts. Therefore, it will lead to a lower sense of formality.

The present invention was completed in view of the above-mentioned problems, and its object is to provide a trousers, which is mainly composed of fabric and can follow the wearer's waist size without reducing the sense of formality. [Technical means to solve the problem]

The trousers (1) of one aspect of the present invention are made of fabric, and have a waist (12) extending at the waist of the wearer, and the waist (12) is provided with an extending direction along the waist (12) The elastic rubber (30) and the front and back parts (31) covering the elastic rubber (30), and the front and back parts (31) are configured to use elastic materials without forming wrinkles. [Effects of Invention]

According to the present invention, it is possible to provide trousers that can follow the wearer's waist size without reducing the sense of formality.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In addition, the same elements are denoted by the same symbols, and repeated descriptions are omitted. Furthermore, the dimensional ratios of the drawings are not limited to the ratios shown in the drawings. In addition, the following embodiments are examples for explaining the present invention, and the present invention is not limited to the embodiments.

FIG. 1 is a front view showing an example of the structure of the trousers 1 of the present embodiment, and FIG. 2 is a rear view of the trousers 1. As shown in FIG. The trousers 1 are those using fabrics such as cloth as the main fabric, such as rompers, slacks, shorts, or flared pants.

The trousers 1 includes, for example, a front piece 10, a back piece 11, a waist 12, and the like.

The front body piece 10 and the back body piece 11 are mainly composed of fabric cloth. For the warp and weft of the fabric, for example, polyester, rayon, polyurethane, silk or cotton yarns are used.

The waist 12 is arranged at the upper end of the trousers 1. The waist 12 spans the front body 10 and the back body 11 of the trousers 1, and has a belt shape along the waist of the wearer. Furthermore, in this manual, "up", "down", "up and down", and "left and right" refer to the trousers 1 shown in Figure 1 and Figure 2 as the reference direction.

As shown in FIGS. 1 to 4, the waist 12 has, for example, a front waist 20 on the front body 10 side and a back waist 21 on the back body 11 side. The front waist portion 20 and the back waist portion 21 are stitched together on both sides of the trousers 1.

The back waist 21 has an elastic rubber 30 arranged along the extension direction of the waist 12 (waist circumference direction) X, the front and back parts 31 of the elastic rubber 30 are covered with the elastic rubber 30 inside, and a plurality of belts are used to pass through. A belt loop 32.

The elastic rubber 30 has, for example, a linear belt shape. The elastic rubber 30 has a general retention rate of 80% or more, for example.

The front and back parts 31 are made of woven fabric which is an elastic material. The so-called elastic material refers to those with an elongation rate of 10% or more measured based on the JIS L 1096 fabric and knitted fabric test method. The elastic material of the front and back parts 31 is preferably one having an elongation of 15% or more, and more preferably one having an elongation of 20% or more. The elastic material of the front and back parts 31 is realized by, for example, weaving a yarn having extensibility such as polyurethane.

As shown in FIG. 5, the front and back portions 31 are formed in a ring shape in a longitudinal section cut on a plane perpendicular to the extension direction X of the waist 12, that is, extending upward from the lower end 31a on the front side. It is folded back at the upper end 31b and extends to the lower end 31c on the back side. Thereby, an internal space 40 extending in the extending direction X of the waist 12 is formed inside the front and back parts 31, and the elastic rubber 30 is arranged in the internal space 40.

The lower end 31a of the front side and the lower end 31c of the back side of the front and back parts 31 are sewn together with the fabric cloth of the back body 11 on the lower side of the waist part 12. This stitching uses a thread 50 of elastic material. That is, the front and back parts 31 are sewn to the back body 11 adjacent to the front and back parts 31 by a thread 50 of elastic material. The elastic material of the thread 50 may be, for example, one having an elongation rate of 15% or more, more preferably 25% or more.

The front and back parts 31 are configured without wrinkles, and the front and back sides maintain a flat shape and can expand and contract. Furthermore, the "wrinkle" in this specification refers to a deliberate pre-production that exists even when the wearer is not wearing the trousers 1, for example. For example, as shown in FIG. 3, the size (unextended size) L1 of the front and back portions 31 in the extension direction X of the back waist portion 21 is approximately the same as the size (natural length) L2 of the elastic rubber 30 in the same interval, for example It is 1.0 times or more and 1.1 times or less of the size L2, more preferably 1.0 times or more and 1.05 times or less of the size L2.

As shown in FIGS. 3 and 4, both ends of the front waist portion 20 and the back waist portion 21 are continuously connected. The front waist portion 20 has, for example, the same structure as the above-mentioned rear waist portion 21 except that the elastic rubber 30 is not provided therein. That is, the front waist portion 20 has a front and back portion 31 and a belt loop 32. Furthermore, the front waist portion 20 is provided with a button 60, a button hole 61 for fastening the button 60, a trouser hook 62, a fastener 63 for fixing the trouser hook 62, and the like.

The belt loops 32 are arranged at specific intervals throughout the waist 12. As shown in FIG. 6, the belt loop 32 is formed in a belt shape, the first end 32a is sewn to the front body 10 or the back body 11 adjacent to the waist 12, and the second end 32b is sewn to the upper part of the back side of the waist 12 nearby. The belt loop 32 is sewn to the elastic rubber 30 and the front and back parts 31 at the back waist 21, and is sewn to the front and back parts 31 at the front waist 20.

As shown in FIG. 7, the belt loop 32 is sewn to the waist 12 in such a way that the suture 70 becomes a square shape. That is, the stitches 70 are formed in a single row so as to have two sides each in the up-down direction and the left-right direction (extending direction X).

According to this embodiment, in the trousers 1 mainly composed of fabric, the waist 12 has an elastic rubber 30 arranged along the extending direction X of the waist 12, and the front surface of the elastic rubber 30 is covered by the elastic rubber 30 inside. And the back part 31, and the front and back part 31 are elastic materials, and are comprised so that it may be wrinkle-free.

Thereby, the front and back parts 31 are extended in the extension direction X of the waist 12 corresponding to the waist size of the wearer, and the elastic rubber 30 inside follows the extension of the front and back parts 31 while imparting a reaction force in the contraction direction. . As a result, the waist 12 expands and contracts with no wrinkles on the front and back 31 of the waist 12.

As a result, in the trousers 1 mainly composed of fabric cloth, it is possible to realize the trousers 1 which does not reduce the sense of formality and which follows the waist size of the wearer.

The back waist portion 21 has elastic rubber 30 and front and back portions 31. The front waist portion 20 does not have the elastic rubber 30. Therefore, only the relatively long back waist portion 21 stretches and contracts, so that the length of the waist portion 12 can be effectively adjusted.

The belt loop 32 is sewn to the front and back portions 31 and the elastic rubber 30 in such a way that the suture 70 becomes a square shape. The previous belt loop suture is performed only with sutures in the extending direction X of the waist 12, but by making the suture 70 a square shape, the suture force can be ensured and the damage to the elastic rubber 30 caused by the suture can be reduced.

In addition, by forming the suture 70 in the direction at right angles to the extending direction X, the load applied to the elastic rubber 30 can be dispersed by the suture 70, thereby preventing the elastic rubber 30 from becoming fragile.

The waist 12 is sewn to the adjacent part (the back piece 11) by a thread 50 of elastic material. Therefore, the thread 50 follows the expansion and contraction of the waist 12. Thereby, when the waist 12 is stretched and contracted, it can be suppressed that the waist 12 is pulled by an adjacent part and wrinkles are generated in the vicinity of the stitching.

The size L1 of the front and back portions 31 in the extension direction X of the waist portion 12 is 1.0 to 1.1 times the size L2 of the elastic rubber 30 constituting the same section as the front and back portions 31. Therefore, the front and back portions 31 are proper It is smoothly structured to be flat without wrinkles.

In this embodiment, the elastic rubber 30 is only provided on the back waist 21, but it can also be provided on the entire waist 12, that is, also on the front waist 20. In this case, the length can be adjusted in the extension direction X of the waist 12 more effectively.

In the above embodiment, as shown in FIG. 8, the back waist 21 has a curved shape protruding toward the hip side of the wearer, and the elastic rubber 30 is curved along the curved shape of the back waist 21. In this case, since the elastic rubber 30 follows the shape of the waist 12, the appearance of the waist 12 becomes beautiful. In addition, the elastic rubber 30 can be expanded and contracted in the extension direction X of the waist 12 smoothly.

In the above embodiment, the elastic rubber 30 is provided in the back waist 21, but the elastic rubber 30 may not be provided in the back waist 21 and only the elastic rubber 30 is provided in the front waist 20.

In the above embodiment, when the elastic rubber 30 is provided on the front waist 20, the elastic rubber 30 may also have a linear belt shape as shown in FIG. 9. In addition, when the front waist portion 20 has a curved shape that is convexly curved toward the wearer's buttocks side like the back waist portion 21 shown in FIG. 8, the elastic rubber 30 may also be curved along the curved shape.

The trousers 1 is not limited to the above-mentioned embodiment. For example, the trousers 1 may be those without belt loops 32. The trousers 1 are not limited to trousers, and may be shorts. As long as the trousers 1 are mainly composed of fabric cloth, fabrics other than the fabric cloth may be partially used. [Industrial availability]
