Abstract

PURPOSE:To obtain a string-shaped material having an elasticity enough to put on and take off clothing and subjected to an effective treatment for prevention of elongation without increasing labors required for production. CONSTITUTION:A rectangular covering cloth 2 made of an elastic fabric such as a knitted fabric is doubled in the longitudinal direction and it is further folded up toward the inside in the neighborhood of both the side end parts to form a pair of folding parts 4a and 4b. A tape-shaped core padding 3 especially made of an elastic material having about 100% recovery of Young's modulus is inserted into one of the folding parts 4a and 4b over almost the whole length of the covering cloth 2 so that the longitudinal elongation of the covering cloth 2 and the core padding 3 may be almost equal to each other under application of the same load in that state. The folding parts 4a and 4b are sewn together through a row of stitching 5 and the covering cloth 2 is formed into a string shape by this row of stitching 5. Further, the covering cloth 2 and the core padding 3 are sewn together, thus the objective shoulder string 1 is formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cord-like body provided on clothes, and is preferably implemented as a shoulder strap.

[0002]

2. Description of the Related Art A string-like body used for clothes, especially a shoulder strap,
It is desired to have sufficient stretchability so that it can be easily put on and taken off and does not slip off when worn. However, if a rubber strap or the like is used as it is as a shoulder strap, there is a problem in that the appearance of the clothing is impaired. Therefore, in recent years, it has been preferred to sew elastic cloth such as knit into a string shape for use.

When a cloth such as a knit is stretched many times, the stretchability deteriorates so that the cloth does not shrink to its original length, and the shoulder strap becomes unnecessarily long. Therefore, a method has been proposed in which a tape made of a material having a relatively low elongation is sewn into the shoulder strap to prevent the elongation. A shoulder strap 31 adopting this method is shown in FIG. The shoulder strap 31 is formed by enclosing an outer cloth 32 such as a knit with a core tape 33 made of, for example, wooly nylon, which has a relatively low elongation rate, and is sewn in a string shape with seams 35. In this state where the core tape 33 is merely inserted into the outer cloth 32, it does not stop the expansion, so that the fine stitch 36 extends over the entire length of the shoulder strap 31 so that the middle tape 33 expands and contracts together with the outer cloth 32. Then, the core tape 33 and the outer envelope 32 are sewn together.

[0004]

However, since such a shoulder strap 31 requires the stitch 36 in addition to the seam 35, the labor at the time of sewing increases. In addition, the core tape 33
Since this hinders the extension of the shoulder strap 31, it is difficult to put on and take off the clothes. An object of the present invention is to provide a cord-like body which has sufficient stretchability for putting on and taking off clothes and which is effectively stretch-prevented without increasing labor in manufacturing.

[0005]

The present invention has taken the following technical means in order to achieve the above object. That is, the present invention is a cord-shaped body that is provided integrally with or separately from clothes, and has an extension rate in the longitudinal direction that is substantially the same as that of the outer envelope made of stretchable fabric, And a tape-shaped core made of a fibrous material having a recovery rate of elongation elasticity of almost 100%, and the outer envelope is sewn in a string shape with the core wrapped around the entire length, and The center core is a string-like body of clothes which is sewn to each other by seams for sewing the outer envelope in a string shape.

Further, it is preferable that the cord-shaped body is used as a shoulder strap. Further, in this cord-shaped body, the core is preferably a rubber cord, and particularly urethane rubber is preferable. Alternatively, in the cord-like body, the core may be formed of spandex fiber.

Further, in the cord-like body of the present invention, the outer envelope made of a knit fabric is folded in two along the longitudinal direction, and both widthwise end portions of the two folded outer envelope are respectively inward. It may be formed so that both the folded-back portions are sewn over the entire length of the outer cloth in a state in which the folded-back portion and the inner core are sandwiched in one of the folded-back portions.

[0008]

According to the present invention, in the cord-like body, since the outer cloth and the central core which is wrapped in the outer cloth over the entire length have elasticity, it is possible to perform the operation of the wearer when putting on and taking off clothes. It expands and contracts. In addition, since the core is made of a fiber material having an elastic recovery rate of almost 100%, when the string state is released from the load,
The outer cloth sewn on the center core also shrinks together with the center core, and reliably returns to its original length. At this time, since the elongation rate of the outer envelope and the core is substantially the same in the longitudinal direction, there is no wrinkling on the outer envelope and the core at any stage of expansion and contraction, and the elastic expansion and contraction is smooth. Therefore, the appearance is beautiful and the wearer has an excellent feeling of wearing.

On the other hand, at the time of sewing, the formation of the cord-like body and the sewing of the outer cloth and the core are performed at the same time, which saves labor.

[0010]

1 is a diagram showing the construction of an embodiment of the present invention, and FIG. 2 is a sectional view thereof. Shoulder strap 1 which is a cord-like body
Includes an outer envelope 2 and a core 3. The outer cloth 2 is a rectangular cloth having elasticity such as a knit cloth.
The core 3 has elasticity, and particularly the elastic recovery rate of elongation is almost 1.
It is a tape-like body formed of a material close to 00%. Preferred is a tape made of spandex such as Mobilon (trademark), or a rubber cord containing synthetic rubber such as urethane rubber or natural rubber. In the case of a rubber cord containing natural rubber, about 70% natural rubber and about 30% rayon are preferable.

As shown in FIG. 1, the outer envelope 2 is folded in two along the longitudinal direction, and the vicinity of both ends in the width direction is folded back inward to form a pair of folded portions 4a and 4b. . The core 3 is sandwiched in one of the folded portions 4a (4b). (In the figure, it is sandwiched between the folded portions 4a.) Alternatively, it may be sandwiched between both folded portions 4a and 4b. The lengths of the outer envelope 2 and the inner core 3 in the longitudinal direction are substantially the same, that is, the inner core 3 is enclosed over substantially the entire length of the outer envelope 2.

In this state, when the same load is applied to the envelope 2 and the core 3, the elongation rates in the longitudinal direction are almost the same. However, a difference in the elongation rate of the outer envelope 2 of about 60% to 140% of the elongation rate of the core 3 is allowed. Core 3
In this state of sandwiching, the folded-back portions 4a and 4b are sewn by, for example, chain stitches 5. With this seam 5,
At the same time that the outer envelope 2 is formed in a string shape, the outer envelope 2 and the core 3 are sewn together to form the shoulder strap 1. The sewn outer covering 2 and the core 3 expand and contract together. As shown in FIG. 3, the shoulder strap 1 is a garment body 1 of a garment 10 such as a camisole.
1. Shoulder is attached.

As described above, the shoulder strap 1 is stretchable and can be easily operated when putting on and taking off clothes and wearing. In addition, as described above, since the elongation rates of the outer envelope 2 and the center core 3 in the longitudinal direction are substantially the same, the expansion and contraction operation is smooth, and the envelope 2 and the center core 3 are in any stage of expansion and contraction. There are no problems such as wrinkles that make them unsightly or stiff and make them uncomfortable to wear.

Further, the core 3 has a recovery rate of elongation elasticity of almost 100% as described above, so that the core 3 is recovered to the original length with the sewn outer covering 2. Therefore, after the shoulder strap 1 is stretched by applying a load, the shoulder strap 1 instantly returns to the original length when released from the load, so that the durability does not change even if the shoulder strap 1 is repeatedly worn, and the durability is improved. On the other hand, at the time of sewing, the formation of the shoulder strap 1 and the sewing of the outer cloth 2 and the core 3 are simultaneously performed in one sewing, which saves labor and cost.

The outer envelope 2 may be a knitted fabric of any knitting method, and a stretchable woven fabric such as spandex may be used. Further, it is more preferable in terms of appearance that the outer wrap 2 and the garment body 11 are made of the same knitted fabric or woven fabric. Further, as shown in FIG. 4, the outer cloth 2 of the shoulder strap 1 and the piping tape 9 for the cloth edge treatment of the upper edge of the garment body 11 may be provided so as to be integrally connected.

FIG. 5 is a simplified diagram showing a sectional view of another embodiment of the present invention. The difference from the above-described first embodiment is the shape of the outer envelope, and the other parts are the same as in the first embodiment, so description will be omitted. Figure 5
(A) shows the center core 3 in the folded-back portion of the outer wrap 21 which is folded in three.
And is sewn by the seam 5. Alternatively, as shown by the alternate long and short dash line in the figure, the core 3 may be sandwiched between the end portion of the outer envelope 21 on the side opposite to the folded portion and the folded portion.

In FIG. 5B, the outer cloth 22 is folded in two,
The center core 3 is sandwiched. In FIG. 5C, two outer envelopes 23a and 23b are folded in two and meshed with each other, and the core 3 is sandwiched between the meshed portions. Alternatively, the center core 3 may be sandwiched at the position indicated by the alternate long and short dash line in the figure. Figure 5
In (D), one end in the width direction of the outer envelope 24 is folded back, and the core 3 is provided so as to be sandwiched between the folded back portions.

In FIG. 5 (E), one end of the outer cloth 25 in the width direction is folded in three and the other end is folded in two.
The center core 3 is sandwiched between the two folded portions or between the folded portions. The core may be provided at any position indicated by a solid line or a one-dot chain line in the figure. In FIG. 5F, the outer envelope 26 has a circumferential shape in which both ends in the width direction overlap each other, and the center core 3 is provided inside. The core may be provided at any position indicated by a solid line or a one-dot chain line in the figure.

Although the single needle sewing is shown in the drawings (A) to (F), it may be double needle sewing. In FIG. 5 (G), both ends in the width direction of the outer envelope 27 are folded back in the same direction, and the core 3 is arranged so that both ends of the core 3 are sandwiched in the folded portions.
Both folded-back portions are sewn by double needle sewing. In the examples shown in (A) to (G) above, the stitching may be either chain stitch or lock stitch, and any stitch such as straight stitch, zigzag stitch, and various pattern stitches may be used. Good.

FIG. 6 is a diagram showing another embodiment of the present invention. The string-shaped body S that is implemented as the shoulder strap 1 such as the camisole in the above-described embodiment can be implemented as a string-shaped body that is provided integrally with or separately from any other clothes. For example, slips (shown in (A) in the figure) for women, shoulder straps for bras, tank top type outerwear (shown in (B) in the figure) for outerwear, and shoulder straps for slip-type dresses , A belt for lower garments such as skirts and pants (shown in (C) in the figure), an opening stop for vests (shown in (D) in the figure), back strap for upper garments (shown in (E) in the figure) And so on.

[0021]

According to the present invention, since the cord-shaped body can be expanded and contracted, it is easy to put on and take off clothes and to perform an operation during wearing. In addition, the expansion and contraction operation is smooth, and there is no problem that the outer cloth and the core are wrinkled at any stage of expansion and contraction, and are uncomfortable, and the feeling of wearing is poor.

Further, since the cord-like body is stretched by applying a load and then immediately returns to its original length when released from the load,
The durability of the string-shaped body and the garment itself is improved without changing the length even after being repeatedly worn. On the other hand, at the time of sewing, the cord-like body is formed and the outer envelope and the core are sewn at the same time, which saves labor.
