Description

[Detailed Description of the Invention] [Industrial field of application] This invention is a cloth accessory that is directly worn on the body, such as clothing such as girdles, corsets, bras with corsets, and medical supplies such as back pain corsets and supporters. To the item
The present invention relates to an elastic core material that is attached by means such as sewing and that has a function of complementing / shaping a body shape and shape-supporting bones, joints, muscles, and the like.

[Conventional technology]

Attaching elastic core material to underwear such as clothing, especially girdle, corset, brassiere with corset, etc., and adjusting the waist shape by attaching it to the body, medical equipment such as corset for lower back pain Similarly, an elastic core material is attached to the back of the wearer to support and protect the wearer's lumbar vertebrae, and the back muscles and abdominal muscles can be assisted to maintain good posture and reduce back pain. Has been done. As an elastic core material for exhibiting such effects, a flat elastic core material formed into a narrow plate shape from a material having moderate hardness and elasticity such as metal and synthetic resin, or the like, has been conventionally used. A rod-shaped elastic core material formed into a slender rod shape by a material has been used. Further, a spiral elastic core material in which a steel wire is spirally wound to form a flat rod shape is also used.

[Problems to be solved by the device]

However, the elastic core material used in the past does not always have sufficient strength, and when wearing clothing or the like to which the core material is attached, or when attaching or detaching it,
Furthermore, it may be deformed or damaged when it is washed. When the elastic core material is deformed or damaged, it is not possible to effectively exert the effect as the elastic core material as described above when the clothing is worn, and it is rather incompatible with the body, and the foreign body feels rather. It may cause discomfort, or even damage the skin due to breakage of the core material. Therefore, when the elastic core material is found to be deformed or damaged, if the repair is impossible, the clothing itself must be discarded.

The present invention provides an elastic core material for a cloth accessory which has sufficient strength, is hardly broken, and can be easily returned to its original shape even if it is deformed. Is a technical issue.

[Means for Solving the Problems]

As a means for achieving the above-mentioned object, the present invention proposes, as a means for achieving the above-mentioned object, a continuous, dense spiral winding of a steel wire in one direction, and the entire length in the axial direction inside the core material body whose outer shape is formed into a flat bar shape. The gist is that the elastic core material is configured by internally providing a core metal made of a shape memory alloy.

The core metal may be configured such that it is wrapped with a synthetic resin material to fill the gap between the core metal and the core material body.

[Action]

The elastic core material having the above-described structure has sufficient strength because the core metal is internally provided over the entire length in the axial direction inside the core material body formed by continuously winding the steel wire in one direction in a spiral shape. And is unlikely to be damaged. In addition, even if the elastic core material is deformed when wearing clothing, etc., when it is put on and taken off, or when it is washed, the core metal is made of a shape memory alloy. Therefore, by storing the optimum shape in the core metal at an appropriate temperature, for example, a temperature corresponding to body temperature,
If the elastic core material is heated to that temperature, it can be easily restored to its original shape.

Further, when the core metal is wrapped in the synthetic resin material so as to fill the gap between the core metal and the core material main body, the core metal does not move inside the core material main body.

〔Example〕

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing a partially broken elastic core material of a cloth accessory according to an embodiment of the present invention. The elastic core material has a flat bar-shaped outer shape and has a space inside thereof.
As shown in the transverse sectional view in FIG. 2, one core metal 2 provided inside the core body 1 over its entire length in the axial direction, and caps at both ends of the core body 1. Metal fitting 3,3
It consists of and. Like the conventional spiral elastic core material, the core body 1 is formed by continuously and densely winding a steel wire in one direction in a spiral shape, and has appropriate hardness and elasticity in any direction. It can also be bent and has excellent shape restoration. The cored bar 2 is made of a shape memory alloy, and the cored bar 2 stores an optimum shape at an appropriate temperature, for example, a temperature corresponding to body temperature.

In this elastic core material, the core metal 2 is provided inside the core material main body 1 and the core material main body 1 is reinforced by the core metal 2, so that the elastic core material has sufficient strength as a whole and may be damaged. Less is. Further, in this elastic core material, since the core metal 2 is made of the formation memory alloy, even if the core metal 2 is not deformed and cannot return to its original shape, if the core metal 2 is heated by body temperature, for example,
It easily returns to its original shape due to the unique properties of shape memory alloys.

The cored bar 2 shown in FIG. 2 has a thin rod shape, and since this rod-shaped cored bar 2 bends in any direction, the above-mentioned characteristics of the core material main body 1 that is bendable in any direction are sufficient. Be utilized by However, the elastic core material should be formed as flat as possible in order to prevent the person wearing the elastic core material from feeling a foreign object when the elastic core material is placed on clothing or the like. Since the gold 2 cannot be made too thick, the elastic core material has a slightly reduced shape retaining force, supporting force, and strength.

On the other hand, the core metal 4 shown in FIG. 3 has a flat plate shape, and its cross-sectional area can be made larger than that of the rod-shaped core metal 2 described above. Can be increased. However, when the cored bar 4 has a flat plate shape, there is a disadvantage that the flexibility of the elastic core material in the left-right direction in FIG. 3 is suppressed. Therefore, the use part of the elastic core material,
It may be determined whether to use a thin rod-shaped cored bar or a flat-plate-shaped cored bar according to the application.

Further, the elastic core material shown in FIG. 4 is an example in which the core metal 5 is wrapped with the synthetic resin material 6 to fill the gap between the core metal 5 and the core material main body 1. By thus filling the gap between the core metal 5 and the core body 1 with the synthetic resin material 6, the core metal 5 does not move or slip inside the core body 1.

The elastic core material having the above-mentioned configuration is attached to a cloth accessory directly attached to the body by means of sewing or the like, as in the conventional one, such as clothing and medical supplies such as underwear,
It is used to shape and shape the body, and to retain the shape of bones, joints and muscles. 5 to 9 show
The various usage forms are shown. FIG. 5 shows an example in which the elastic core member 8 is attached to the brassiere 7 with a corset, and FIG. 6 shows an example in which the elastic core member 10 is attached to the high waist girdle 9,
