Description

Trouser

The present invention relates to a trouser.

Trousers are represented by various names such as suits, slacks, pants or pantalons. The trouser here refers to a trouser mainly composed of woven fabric. A trouser made of such a woven fabric has a lower elasticity than a knitted fabric, but can be used in a beautiful finish in appearance and can be used not only in casual situations but also in formal situations.

By the way, in the above-mentioned types of trousers, the length of the waist portion is generally constant, and the length of the waist portion cannot be adjusted according to the waist size of the wearer.

In this regard, in recent years, a trouser of this type has been developed in which a part of the waist portion 100 is composed of a rubber portion 101 as shown in FIG. In this case, since the rubber portion 101 expands and contracts, the length of the waist portion 100 fluctuates and can follow the waist size of the wearer. Patent Document 1 discloses slacks using a stretch material for the entire waist portion.

JP-A-2015-78447

However, when a part of the waist portion 100 is composed of the rubber portion 101 as described above, the rubber portion 101 is exposed, so that the formal feeling is lowered.

Furthermore, in order to solve the above problem, it is conceivable to install elastic rubber in the waist part. However, in this case, it is necessary to make the dimensions of the front and back surfaces covering the elastic rubber longer than those of the elastic rubber by the amount of extension of the elastic rubber, and to make so-called gathers on the front and back surfaces. For this reason, the formal feeling is rather lowered.

The present invention has been made in view of this point, and an object of the present invention is to provide a trouser mainly composed of a woven fabric, which can follow the waist size of the wearer without deteriorating the formal feeling. And.

The trouser (1) according to one aspect of the present invention includes a waist portion (12) extending to the waist position of the wearer in the trouser (1) made of a woven fabric, and the waist portion (12) is a waist portion (12). An elastic rubber (30) provided along the extending direction of the waist portion (12) and a front / back surface portion (31) covering the elastic rubber (30) are provided, and a stretch material is used for the front / back surface portion (31). It is configured so that gathers are not formed.

According to the present invention, it is possible to provide a trouser that can follow the waist size of the wearer without deteriorating the formal feeling.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. The same elements are designated by the same reference numerals, and duplicate description will be omitted. Furthermore, the dimensional ratios in the drawings are not limited to the ratios shown. Further, the following embodiments are examples for explaining the present invention, and the present invention is not limited to this embodiment.

FIG. 1 is a front view showing an example of the configuration of the trouser 1 according to the present embodiment, and FIG. 2 is a rear view of the trouser 1. The trouser 1 uses a woven fabric such as cloth as the main fabric, and is, for example, a suit, slacks, pants, or pantalon.

The trouser 1 includes, for example, a front body 10, a back body 11, a waist portion 12, and the like.

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

The waist portion 12 is provided at the upper end portion of the trouser 1. The waist portion 12 has a band shape along the waist circumference of the wearer over the front body 10 and the back body 11 of the trouser 1. In the present specification, "upper", "lower", "upper and lower", and "left and right" are directions based on the trouser 1 shown in FIGS. 1 and 2.

As shown in FIGS. 1 to 4, the waist portion 12 has, for example, a front waist portion 20 located on the front body 10 side and a back waist portion 21 located on the back body 11 side. The front waist portion 20 and the back waist portion 21 are sewn to each other on both side portions of the trouser 1.

The back waist portion 21 includes an elastic rubber 30 provided along the extension direction (waist circumference direction) X of the waist portion 12, a front and back surface portion 31 covering the elastic rubber 30 so as to internally install the elastic rubber 30, and a belt. It has a plurality of belt loops 32 for hanging the rubber.

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

The front and back portions 31 are made of a woven fabric that is a stretch material. The stretch material means a material having an elongation rate of 10% or more measured based on the fabric test method of JIS L 1096 woven fabric and knitted fabric. The stretch material of the front and back portions 31 is preferably, for example, one having an elongation rate of 15% or more, and more preferably one having an elongation rate of 20% or more. The stretch material of the front and back portions 31 is realized by weaving an extensible thread such as polyurethane.

As shown in FIG. 5, the front and back surfaces 31 extend upward from the lower end 31a on the front surface side in a vertical cross section cut along a plane perpendicular to the extension direction X of the waist portion 12, fold back at the upper end 31b, and are folded back on the back surface side. It is formed in a loop shape extending to the lower end 31c of the. As a result, an internal space 40 extending in the extending direction X of the waist portion 12 is formed inside the front and back surface portions 31, and the elastic rubber 30 is arranged in the internal space 40.

The lower end portion 31a on the front surface side and the lower end portion 31c on the back surface side of the front and back surface portions 31 are sewn together with the woven fabric of the back body 11 on the lower side of the waist portion 12. A stretch material thread 50 is used for this sewing. That is, the front and back surface portions 31 are attached to the back body 11 adjacent to the front and back surface portions 31 by the threads 50 of the stretch material. The stretch material of the yarn 50 may have, for example, an elongation rate of 15% or more, more preferably 25% or more.

The front and back surfaces 31 have no gathers and are configured so that the front and back surfaces expand and contract while maintaining a flat shape. The term "gather" as used herein refers to something that is intentionally created in advance so that it exists even when the wearer is not wearing the trouser 1. For example, the dimension (dimension when not stretched) L1 of the front and back portions 31 of the extension direction X of the back waist portion 21 shown in FIG. 3 is substantially the same as the dimension (natural length) L2 of the elastic rubber 30 in the same section, for example. It is 1.0 times or more and 1.1 times or less of the dimension L2, and more preferably 1.0 times or more and 1.05 times or less of the dimension L2.

The front waist portion 20 is continuously connected to both ends of the back waist portion 21 as shown in FIGS. 3 and 4. The front waist portion 20 has the same structure as the back waist portion 21 except that, for example, the elastic rubber 30 is not provided internally. That is, the front waist portion 20 has a front / back surface portion 31 and a belt loop 32. Further, the front waist portion 20 includes a button 60, a buttonhole 61 for fastening the button 60, a stitch 62, a fastener 63 for fastening the stitch 62, and the like.

Belt loops 32 are provided at predetermined intervals over the entire waist portion 12. As shown in FIG. 6, the belt loop 32 is formed in a band shape, the first end portion 32a is sewn to the front body 10 or the back body 11 adjacent to the waist portion 12, and the second end portion 32b is the waist portion. It is sewn near the upper part on the back surface side of the twelve. The belt loop 32 is sewn to the elastic rubber 30 and the front and back surfaces 31 at the back waist portion 21, and is sewn to the front and back surfaces 31 at the front waist portion 20.

As shown in FIG. 7, the belt loop 32 is sewn so that the sewing line 70 is square with respect to the waist portion 12. That is, the sewing line 70 is formed in a one-stroke shape so as to have two sides in each of the vertical direction and the horizontal direction (extension direction X).

According to the present embodiment, in the trouser 1 mainly composed of the woven fabric, the waist portion 12 is provided with the elastic rubber 30 provided along the extending direction X of the waist portion 12 and the elastic rubber 30 internally. The front and back portions 31 that cover the elastic rubber 30 are provided, and the front and back portions 31 are made of a stretch material and are configured so as not to have gathers.

As a result, the front and back portions 31 extend in the extending direction X of the waist portion 12 according to the waist size of the wearer, and the elastic rubber 30 inside follows the elongation of the front and back portions 31 while shrinking in the direction of contraction. Give power. As a result, the waist portion 12 expands and contracts without gathers on the front and back surfaces 31 of the waist portion 12.

Therefore, in the trouser 1 mainly composed of the woven fabric, it is possible to realize the trouser 1 that follows the waist size of the wearer without deteriorating the formal feeling.

Since the back waist portion 21 has the elastic rubber 30 and the front and back surfaces 31 and the front waist portion 20 does not have the elastic rubber 30, only the relatively long back waist portion 21 expands and contracts, and the length of the waist portion 12 is long. The adjustment of the rubber can be done effectively.

The belt loop 32 is sewn to the front and back portions 31 and the elastic rubber 30 so that the sewing line 70 has a rectangular shape. Conventionally, the belt loop is sewn only on the sewing line of the waist portion 12 in the extending direction X, but by making the sewing line 70 square, damage due to sewing to the elastic rubber 30 while ensuring the sewing force. Can be reduced.

Further, by forming the sewing line 70 in the direction perpendicular to the extending direction X, the load applied to the elastic rubber 30 can be dispersed through the sewing line 70, and the elastic rubber 30 can be prevented from being easily cut.

Since the waist portion 12 is sewn with the thread 50 of the stretch material to the portion adjacent to the waist portion 12 (rear body 11), the thread 50 follows the expansion and contraction of the waist portion 12. As a result, it is possible to prevent the waist portion 12 from being pulled by the adjacent portion and wrinkling in the vicinity of sewing when the waist portion 12 is expanded or contracted.

Since the dimension L1 of the front and back portions 31 in the extending direction X of the waist portion 12 is 1.0 times or more and 1.1 times or less of the dimension L2 of the elastic rubber 30 forming the same section as the front and back portions 31, the front and back portions 31 is preferably configured flat so that there is no gathering.

In the present embodiment, the elastic rubber 30 is provided only on the back waist portion 21, but may be provided on the entire waist portion 12, that is, on the front waist portion 20 as well. In such a case, the length of the waist portion 12 is adjusted more effectively in the extending direction X.

In the above embodiment, as shown in FIG. 8, the back waist portion 21 has a convex curved shape on the buttocks side of the wearer, and the elastic rubber 30 is curved along the curved shape of the back waist portion 21. You may be. In such a case, since the elastic rubber 30 follows the shape of the waist portion 12, the appearance of the waist portion 12 becomes beautiful. Further, the elastic rubber 30 is preferably expanded and contracted in the extending direction X of the waist portion 12.

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

In the above embodiment, when the elastic rubber 30 is provided on the front waist portion 20, the elastic rubber 30 may have a straight band shape as shown in FIG. Further, similarly to the back waist portion 21 shown in FIG. 8, when the front waist portion 20 has a curved shape that is convexly curved toward the buttocks of the wearer, it is curved along the curved shape. May be good.

The trouser 1 is not limited to that of the above embodiment. For example, the trouser 1 may not have the belt loop 32. The trouser 1 is not limited to long trousers, but may be short trousers. The trauser 1 may be mainly composed of a woven fabric, and may be partially made of a material other than the woven fabric.

The present invention is useful in providing a trouser that is mainly composed of a woven fabric and that can follow the waist size of the wearer without deteriorating the formal feeling.
