Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to slacks, and more particularly to a skirt structure capable of being extended stepwise in a slack and a method for forming the skirt structure.

[0002]

2. Description of the Related Art Conventionally, slacks that are comfortable to wear such as fit and wear and have excellent design have been required. Then, the tailoring technology and materials have been developed, and nowadays, the ones which are extremely excellent in terms of design and comfort are put on the market.

In recent years, however, even in this field, customer needs have been diversified or individualized, and in view of the trend, it is sufficient to pursue designability, or comfort such as fit and wearability. It is not going to go. In particular, recently, there has been a movement to pursue functionality that has not been so much conscious of in the past.

By the way, clothes for people in a growing period,
Especially for school clothes, the wearing period is extremely limited. The reason for this is that because of the height of growth, the growth of the height is fast and the slacks become shorter immediately than the length of the lower limbs. Therefore, even before the expiry date of the slacks land, it must be changed to a longer slacks. That is, even though the slacks are in good working order, it is necessary to dispose of them and purchase a new larger slacks. This is extremely uneconomical. In order to save money, the only way to extend the relatively short inseam, that is, to lengthen the slacks, is to extend the hem (particularly the hem folding allowance).

To this end, as shown in the procedure of FIG. 8, after the Lewis sewn portion is unwound [FIG. 8 (A) → FIG. 8 (B)], the shoe-rubbing prevention cloth already sewn is once removed. [FIG. 8 (B) → FIG. 8 (C)] must be reattached. [FIG. 8 (D)] After that, the folded-back portion of the hem needs to be sewn again. By the way, in this case, a rake stitch sewing machine or a chopstick sewing machine is used to perform work such as bending up to make a back festival or edging.

As described above, in order to extend the length of the slacks, a special sewing technique and skill of sewing are required. In addition, as can be seen from FIG. 8D, the length of the folded-back portion of the hem is inevitably shortened, which is not always satisfactory in terms of external shape. On the other hand,
When removing the anti-skid cloth, scissors and blades may damage the fabric.

In view of the above, a method has been developed in which the hem of the slacks having the double hem is formed in double from the beginning. In this method, when the height is increased, the double-formed hem portion can be unwound and lengthened. As a result, the leg length is changed to a normal single hem and the crotch length is extended by a certain length. In this way, since the length can be increased according to the height, it is extremely useful for a growing child. However, even in this method, the shoe-rubbing prevention cloth must be reattached after the hem is unraveled.

For this reason, as mentioned above, a person who requires a skilled sewing technique and who cannot do it will eventually
It will be left to the experts for a fee. Furthermore, it can be applied when the hem of the slacks is double, and the length of the hem of the single can not be extended. In recent years, the hem of the single has become larger than that of the double, and it has become necessary to increase the length of the hem of the single.

[0009]

The present invention has been made against the background of such technical problems. That is, an object of the present invention is to provide a hemming structure in which the length of the slacks can be easily extended and at the same time, the hemming portion can be easily formed. Furthermore, it is to provide a hemming method therefor.

[0010]

The inventors of the present invention, as a result of earnest research on such a problem,
In the hem of the slacks, it was found that the hem can be easily and gradually stepped up by considering how to arrange the shoe-rubbing prevention cloth and how to fold it, and the present invention was completed based on this finding. It is a thing.

That is, the present invention (1) has a hem-height structure capable of extending the slacks length, in which a shoe-rubbing prevention cloth is sewn to the hem of the back body, and the shoe-rubbing prevention cloth is partially formed. The bag is folded inward like a bag, and it is sewn in a ring shape on the back body so as to cover the folded part, and the anti-shoe cloth is partially exposed on the back side and not exposed on the front side. It exists in the hemming structure where the hem mouth is sewn in the state.

(2) By unfastening the sewn hem mouth, the upper end of the bag-shaped folded state can be pulled out to expose the shoe-rubbing prevention cloth on the back side. It exists in the hemming structure.

Further, (3) is a slacks length extensible hem-up structure in which a shoe-rubbing-prevention cloth is sewn on the hem of the back body, and the shoe-rubbing-prevention cloth is partially left. It is folded inside in a bag shape, and a seam is formed in the bag-shaped folded state part. It is sewn in a ring shape on the back body so as to cover the folded state part, and a shoe rub prevention cloth. However, there is a hem-up structure in which the hem mouth is sewn with a part exposed on the back side and not exposed on the front side.

Further, (4), by unfolding the folded state, it becomes possible to pull out the middle stitched portion and expose a part of the shoe rub prevention cloth on the back side and not expose it on the front side. There is a hemming structure.

Further, (5), there is a hemming structure in which a plurality of sewn portions in the folded state are formed.

Further, (6), there is a hemming structure in which the sewn portion in the folded state is sewn with a color thread that is easily visible.

Further, (7) the slacks according to any one of claims 1 to 6 having the hem-raising structure.

Further, (8) is a method of forming a hem raising structure capable of extending the slacks length, wherein shoe rub-preventing cloth is sewn on the front hem of the back body and part of the shoe rub-preventing cloth is sewn. And sew the bottom of the bag in a folded state, and sew the hem mouth in a loop so as to cover the folded state at the back body, and the shoe rub cloth is partially exposed on the back side and the front side is exposed. It exists in the method of forming the hemming structure, which is characterized in that it is not exposed to the outside.

Further, (9) the method for forming a hem-up structure in which a plurality of sewn portions are formed in the folded state portion and the slacks length can be extended stepwise.

Further, (10) a method of forming a hem-up structure in which the degree of extension of the slacks length is changed stepwise by changing the positions of a plurality of stitched portions.

According to the present invention, as long as it is in accordance with this object, a substantial hemming structure in which two or more selected from the above 1 to 7 are combined, and 2 selected from 8 to 10 are used. Substantial configurations in which three or more are combined can also be adopted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to specific drawings. (First Embodiment) FIGS. 1A and 1B are views showing the entire slacks (trousers), (A) showing before lengthening and (B) showing after lengthening. In addition, for reference, (C) shows the second step after the height of the second embodiment. Slacks is one back body 1
And one front body 3 are sewn together to form a hollow leg into which the lower leg can be inserted.

FIG. 2 is a schematic view showing a hem raising structure in the slacks (trousers) of the present invention, in which a cross section of a rear body portion is shown. (A) shows the hem-up part before lengthening, and (B) shows the hem-up part after lengthening. Then, a shoe rub prevention cloth 2 having a wide width of 6 to 8 cm (for example, 6 cm) is sewn to a hem portion of the rear body 1 at a position apart from a lower end thereof by a certain distance (see FIG. 4 (A)). .

Incidentally, in the conventional (ordinary) slacks, the shoe-rubbing-preventing cloth 2 has a short width of about 2 to 3 cm (for example, 2 cm) at a position separated from the lower end of the hem part by a common cloth. (See FIG. 8B).
The length of this anti-skid cloth 2 is the same as that of the back body 1 as usual.
It is preferable to make it slightly shorter than the width. For your reference,
FIG. 3 is a diagram showing the length of the shoe-rubbing prevention cloth with the back side being exposed.

By the way, as shown in FIG.
The sewn-in portion (this portion is a double layer of the back body 1 and the shoe-rubbing prevention cloth 21) is folded inward in a bag shape, leaving a part thereof, to form a bag-shaped portion F. ing. In this case, the shoe-rubbing prevention cloth 2 is partially sewn at the hem folding margin (the shoe-rubbing prevention cloth 22) and is not exposed on the front side, and is sewn. The so-called hem mouth F1 of the bag-shaped portion F
Is sutured and the bag part is closed. Then, the back body is folded inward (toward the human foot), and then the body 1 is sewn into a ring shape (a trapezoidal shape) so as to cover the folded portion. In this sewing, the upper end portion P of the hem folding margin is usually sewn with a Lewis sewing machine. The sewing of the hem opening F1 must be performed by the sewing machine before the upper end P is sewn. As described above, the hem portion A is formed.

(Forming Method of Hem Lifting Structure) FIG. 4 is a diagram showing a procedure of forming the hemming structure. FIG. 4 (A) shows a state in which a shoe rub prevention cloth is sewn on the front hem of the back body. (B) shows a state in which a part of the shoe-rubbing prevention cloth is left and folded inward in a bag shape,
(C) is a state in which the hem mouth of the folded state is sewn,
(D) shows a state in which the back body is sewn in a ring shape so as to cover the folded portion.

To form the hem, the procedure as shown in FIG. 4 is performed. First, the wide anti-shoe cloth 2 is sewn to the front hem of the back body 1 at a position apart from the lower end by a certain distance (see FIG. 4 (A)). Next, a part of the shoe rub prevention cloth 2 is left and folded in a bag shape [FIG. 4 (B)].
reference〕. And the hem mouth F of the portion F folded in a bag shape
1 is sewn [see FIG. 4 (C)]. Further, the back body 1 is bent and sewn into a ring shape (a trapezoidal shape) so as to cover the folded portion F (sewn portion P) [see FIG. 4 (D)]. As a result, a hem-raising structure is formed in which the shoe-rubbing prevention cloth 2 is partially exposed on the back side and not exposed on the front side.

(How to adjust the length of the hem up) Now, in order to lengthen (extend) the length of the slacks by unraveling the hem up structure as described above, first, before hem up (before extension) From the state [see FIG. 2 (A)], the suture thread (two back body materials are sewn at the same time with the sewing machine) at the lower end portion of the hem raising portion (that is, the hem opening F1) is cut and removed. With this, the bag-shaped portion (portion folded in a bag shape) F is opened, so that it can be easily pulled out (turned over). By being pulled out downward, the upper end portion P of the bag-shaped portion F
Appears and is located at the lower end of the slacks [(see FIG. 2B)].

In this lengthened state (extended state), the shoe-rubbing prevention cloth 2 is not exposed at all on the front side, but is entirely exposed on the back side. And the area exposed on the back side is a certain width portion from the lower end of the slacks [shoe rub prevention cloth 2
All of (21 + 22)]. In the finally lengthened hem-up portion A, the shoe-rubbing prevention cloth 2 of the bag-shaped portion F is completely exposed on the back side, and the folding margin of the hem-up portion is extended by the width L.
That is, the length of the slacks is extended by the length L. As described above, in order to extend the length of the slacks, unsewn the hem mouth F1 may be unfastened, specifically, the operation of simply cutting and removing the suture thread sewn at the hem mouth F1,
It is extremely simple and easy for an amateur to do.

(Second Embodiment) In this embodiment,
This is an example in which slacks length can be extended in two steps. Figure 5
[Fig. 3] is a schematic view showing a hem with a two-stage extension, where (A) is a hem of the hem before the lengthening, (B) is a hem of the first length after the lengthening, and ( C) shows the hem-height portion after the lengthening of the second stage. The structure of the hem portion A is almost the same as that of the first embodiment.

That is, the anti-shoe cloth 2 is sewn to the front hem of the back body 1, and a wide cloth is sewn to the back hem 1 at a certain distance from the end of the hem. The rear body 1 is bent inward (toward the human foot), and the upper end portion P of the hem folding margin is sewn (for example, oversewn with a Lewis sewing machine).

Further, a portion where the shoe-rubbing prevention cloth 2 is sewn (this portion is a double layer of the back body 1 and the shoe-rubbing prevention cloth 21) is folded inward in a bag shape, leaving a part thereof. Is a bag-shaped portion F. In this case, the shoe-rubbing prevention cloth 2 is sewn in such a manner that a part (the shoe-rubbing prevention cloth 23) is exposed on the back side at the hem folding margin and is not exposed on the front side at all. The hem opening F1 of the bag-shaped portion F is sewn, but this sewn is performed before the above-mentioned upper end P is sewn.

Here, further, the middle position (intermediate stitching portion X1) of the bag-shaped portion F is intentionally stitched.
For the stitching of the intermediate stitching portion X1, it is preferable to use color yarns and perform sewing with coarse stitches so that it is easy to see when cutting the yarns during lengthening work. As described above, the present embodiment differs from the first embodiment in that, in addition to the hem opening F1, another sewn portion is formed in the bag-shaped portion F.

The method of forming the skirting structure in this embodiment may be performed by referring to the method of forming the skirting structure in the first embodiment. However, since it is stepwise, the number of stitches to be formed in the stitched portion of the bag-shaped portion (folded portion) F only increases, and naturally, the stitched portion of this stitched portion fits the stitch at the hem mouth. You can go back and forth.

(Method of extending the second step of the hem up portion) (Extension of the first step) First, from the state before the length is extended (see FIG. 5A), the lower end portion of the hem up portion (that is, the hem mouth F1) Cut the suture (corresponding to the above) and remove it. Since the bag-shaped portion F is now opened, it can be easily turned over and pulled out. When it is pulled out downward, the stitched portion X1 appears and is positioned at the lower end of the slacks [see FIG. 5 (B)].

In the lengthened state (extended state), as is apparent from the figure, the shoe-rubbing prevention cloth 2 (22, 23) is exposed only on the back side and is not exposed on the front side at all. Then, the new region exposed on the back side is a part (a part 22 of the shoe-rubbing prevention cloth) having a constant width from the lower end of the slacks. That is, the slacks length is extended by the length L1.
In the hem raised portion A extended in this way, the position of the intermediate stitching portion X1 of the bag-shaped portion F becomes the lower end (hem opening) of the slacks, and the shoe rub prevention cloth 22 is further exposed to the back side and the hem raised portion is It is extended by the width L1.

(Extending the Second Stage) Next, the sutured portion of the bottom end F1 of the slacks, that is, the suture thread of the intermediate sutured portion X1 is cut and removed. Since the bag-shaped portion F is now opened, it can be easily turned over and pulled out. When pulled out to the outside, the upper end F2 of the bag-shaped portion F appears,
Located at the bottom of the slacks [Fig. 5 (C), Fig. 1 (C)]
reference〕. In this extended state, the shoe rub prevention cloth 2 (21,
22 and 23) are exposed only on the back side and are not exposed at all on the front side. This state is the same as the extended state in the first embodiment.

In the hem-raised portion A thus extended, the position of the upper end portion P of the bag-shaped portion F becomes the lower end of the slacks, and the shoe rub prevention cloth 2 (21, 21, 2) originally in the bag-shaped portion is provided.
2) is completely exposed on the back side, and as a result, the hem raised portion A is extended by the width L1 + L2. That is, the length of the slacks is extended by the length L1 + L2. In this way, in order to extend the length of the slacks in two steps, it is sufficient to simply cut and remove the suture thread of the hem opening F twice, and the work is extremely simple and can be performed by an amateur. Moreover, by appropriately selecting the lengths of L1 and L2, the extension degree in each stage of the slacks length can be freely changed. In this embodiment, since the length of the slacks slack can be adjusted twice for a child such as a student who is in the growing season, the service life of the slacks becomes long.

(Other Embodiments) In the above embodiments, the intermediate stitching portion of the bag-shaped portion F is provided at one location, but it is also possible to have a plurality of N locations at two or more locations. In this case as well, it is preferable to use colored threads and perform stitch sewing with rough stitches so that the threads can be visually recognized easily.

FIG. 6 is a schematic view showing several stepwise hemming structures in the slacks. (A) is a hemming portion before lengthening, (B) is a hemming portion after lengthening, ( C) shows the hem after the lengthening in several stages. In this case, the slacks length can be extended stepwise, and the number of extended steps is N-1. Then, the degree of extension of the slacks length can be changed by changing and setting the intervals between the intermediate stitched portions.

Although the present invention has been described above, it is needless to say that the present invention is not limited to the embodiments and various other modifications can be made without departing from the essence thereof. Although described as slacks (trousers), it is naturally applicable to lengthening of hem such as skirt (see FIG. 7), jacket, coat and cuffs.

[0042]

The length of the slacks or the like is extremely convenient because it can be extended by simple work without remaking the hem.
Also, the slacks length can be easily extended in several stages. The slacks length can be adjusted according to the growth, so the service life is increased.
