Description

[Detailed description of the invention] <<Industrial application>> This invention is used for clothing worn on the human body, such as brassieres, by being sewn into designated areas to maintain the normal external shape of the clothing. The present invention relates to a core material for clothing made of a spring elastic material.

《Prior art》 As is known, this type of core material includes (a) those using synthetic resin materials (Utility Model Application No. 129907/1983, and No. 74007/1983), and (b) stainless steel. etc. (Japanese Unexamined Patent Application No. 58-54438, Utility Model Application No. 54-54437), and (c) those using shape memory alloys (Unexamined Japanese Patent Application No. 58-13706, Utility Model Application No. 60-1983). −89205
However, in the case of (a) above, once formed into a specific shape, it is impossible to deform and use it, and it is vulnerable to external pressure and deforms quickly. In contrast, in the case of (b), although it has an elastic return force and has a shaping function, when subjected to unwanted external pressure, such as when washing, for example, Since the restoring force against the deformation is small, it remains deformed and cannot be reused, or it must be manually restored to its original shape.

In addition, in any of the above cases (a), (b), and (c), the core material for clothing that has been used so far is a round wire rod as shown in Figure 3b, curved as shown in Figure 3a, As shown in Figure c, a material made of a slightly curved plate material is used, or even a pipe-shaped material is used as the material, as shown in Figure d.

As a result, if you try to increase the strength of round wire material for shaping, you have to use a fairly thick material, which not only makes it heavy, but even if the shaping effect of the clothing is good, However, it is difficult to satisfy the wearing feeling, that is, the feeling of conformity to the human body surface, and there is also a risk that the brassiere wire may cause pain or discomfort when it comes into contact with the body.

In addition, in the case of using the above-mentioned curved plate material, its cross-sectional shape S is approximately rectangular, and therefore, in order to provide the required strength, it must be considerably heavy, and its inner surface in the width direction W ₁ Since the outer surface _W2 in the width direction is curved and curved as shown in Figure 3 a, the arrow
Although the resistance (spreading stiffness) against the force that tries to spread in the P ₁ and P ₂ directions is large, and therefore a desirable result can be obtained in shaping the clothing, the bending stiffness in the thickness d direction of the cross-sectional shape S It also has the disadvantage that it becomes quite large, making it less comfortable to fit the body.

Furthermore, when using the pipe-shaped material shown in Fig. 3d,
Although it is possible to reduce the weight compared to the above-mentioned round wire rod, it has to be thicker to increase the rigidity when expanded, and the bending rigidity increases, resulting in poor fitting feeling, and it is susceptible to buckling due to external force.
There are problems such as difficulty in returning to the original shape.

On the other hand, even if a shape memory alloy is used as in (c) above, if the material is made of a material such as the round wire rod, the stability is poor and the material fluctuates unexpectedly, so shape memory treatment is required. cannot be performed stably, resulting in poor quality.

<<Problem to be solved by the invention>> The present application was studied in view of the above-mentioned defects of the conventional example, and in the case of the core material for clothing according to the present invention, a spring elastic material is added to the main line of the core material. By adopting this method, the required parts of clothing can be maintained in a taut state so that they are always shaped, and buckling deformation does not occur even when subjected to external pressure during washing etc. The first is that It is a purpose.

Furthermore, by forming the main core material into a band plate having a specific irregular shape, that is, a substantially C-shaped cross-sectional shape, and curving this in the width direction instead of the thickness direction, it is possible to make the core material relatively thin. In addition to increasing the spreading rigidity described above and satisfying the shaping function of clothing, the thinning described above reduces bending rigidity and not only improves the fit to the body surface. The second purpose is to achieve considerable weight reduction by forming the C-shaped cross section as described above.

By forming one or both of the outer end surfaces, which are the front and back sides of the main line of the core material, to be parallel to the center line in the thickness direction of the C-shaped cross-sectional shape, When the core material for clothing is sewn into a bra, etc. and assembled, it is stable in the state covered by the fabric and does not move or twist unexpectedly, which is desirable from the standpoint of shaping and fit. When something is obtained and a shape memory alloy is used, it can be stabilized by pressing it.
This enables desirable shape memory processing,
The third purpose is to be able to efficiently produce products of stable quality.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present application has a core main line formed of a spring elastic material, which has a flat band-like part with a predetermined width, and grooves formed from both sides in the width direction. The core material main line is formed into a substantially C-shaped cross section by a pair of protrusions protruding through the core material, and the core material main line is formed into a desired shape by curving each of the inner and outer end surfaces in the width direction, and , one or both of the outer end surface of the flat plate band-like part in the thickness direction of the core material main line and the outer end surface of the protruding strip are parallel to the center line in the thickness direction of the C-shaped cross-sectional shape. The purpose of the present invention is to provide a core material for clothing formed of.

<<Operation>> When using the core material for clothing of the present invention, even if an external force is applied to both free ends of the main line of the core material in the direction of widening or narrowing it, the resistance against this is large, and the shaping of the clothing is therefore large. The function (spreading rigidity) is large.

This is because the core main line is curved in the direction in which the inner end face in the width direction and the outer end face in the width direction are curved, and therefore the core main line is bent in the thickness direction, that is, the bending rigidity It becomes weaker and easily adapts to the body, giving a good fit.

In addition, since the material is a spring elastic material, it will return to its original shape by itself even if it receives an unexpected external force, and will not remain deformed or buckled.

Furthermore, since the cross-sectional shape of the main wire is C-shaped due to the flat strip and a pair of protrusions protruding from this, the bending rigidity is weak, and since it is made of a spring elastic material, Buckling is also less likely to occur in the thickness direction.

Further, since one or both of the outer end face of the flat plate band-shaped portion or the outer end faces of the pair of protrusions is parallel to the center line in the thickness direction of the cross-sectional shape,
It can be fixed in a stable state by pressing it into a predetermined location, making it easy to perform shape memory treatment.Furthermore, when sewn into clothing, the core material of this clothing can be involuntarily moved in the fabric of the clothing. This will not reduce the orthopedic function or worsen the fit to the body.

《Example》 Regarding the present application, with reference to Figures 1 and 2 below,
To describe this in detail, the core main wire 1 is made of a spring steel material such as a piano wire, a hard steel wire, or a stainless steel wire, or a spring elastic material made of a shape memory alloy material.

First, let me explain about the above materials.
The former steel material for springs has a large elastic restoring force and can be processed into wires and freely shaped in cross-section.

On the other hand, the latter shape memory alloy material has an alloy composition of Ni-Ti, and its characteristics are that when external force is applied in the martensitic state, the deformation is completed through twin deformation; Since the connections between the crystals remain the same before and after external force is applied, they return to the parent phase when heated, but
At that time, the deformation strain is also eliminated.

Since the transformation point of a shape memory alloy changes depending on the composition ratio of Ti and Ni or the memory treatment temperature, it is possible to adjust the transformation point.

In addition, as is known, there is a superelastic material among shape memory alloys, which is also the same Ti-Ni alloy, but it can be obtained by slightly changing the composition and keeping the heat treatment temperature low. By applying martensitic transformation to a superelastic material at a temperature much lower than body temperature, it is possible to always maintain the ability to return to shape against deformation.

As mentioned above, the core main line 1 made of a spring elastic material is
It is one-dimensionally curved when viewed from the front as shown in Fig. 1a, but as shown in Fig. 1b, a perspective view taken along the line A-A in Fig. 1a is shown in Fig. 1b.
The cross-sectional shape 2 is formed by a flat plate band-shaped portion 2a having a predetermined width W, and a pair of protrusions 2b and 2c that protrude orthogonally from both sides in the width direction via a grooved groove 3.
It is formed in a substantially C-shape.

Therefore, the core main line 1 is curved in a direction in which the inner end surface 2d in the width direction and the outer end surface 2e in the width direction are curved.

Further, regarding the above-mentioned cross-sectional shape 2, referring to FIG. Corner parts 4a, 4b, 4c, 4
d, and the concave grooves 3 are omitted from the protrusions 2b and 2c, and in the present invention, the main line of the core material is 1, the outer end surface 2f of the flat plate band-shaped portion 2a in the direction D
One or both of the outer end surfaces 2g and 2h of the protrusions 2b and 2c are formed in parallel.

Here, in FIG. 2, the Y-Y line is the center line in the width W direction of the cross-sectional shape 2, and in the illustrated example, the inner end surface 2d in the width direction and the outer end surface 2e in the width direction of the core main line 1 are , is formed in a protruding arc shape symmetrically with respect to the center line Y-Y line.

The core main wire 1 can be formed by cutting or wire drawing, and then processed into a desired external shape such as a semicircular shape or a circular shape as shown in FIG. 1a.

Of course, it goes without saying that the final processed shape must match the shape of the clothing to be used.

In the case of a shape memory alloy, processing is completed by performing shape memory treatment.

The transformation point by the shape memory processing is set at a temperature at which transformation occurs by sensing the body temperature of the human body.

The core material for clothing explained above is used by being sewn into the required part of the intended clothing, so that the bra etc. can be shaped into the desired shape, and even if external pressure is applied, the main core material will remain intact. Due to the spreading rigidity of the core material 1, it returns to its original shape and maintains the shaping function, and together with the moderately weak bending rigidity of the core material main line 1, it also exhibits a good fit against the surface of the body. Become.

<<Effect of the invention>> Since the present application is structured as described above,
According to the present invention, there is no buckling due to the core main line made of a spring elastic material, and the original shape can be maintained for a long period of time even when undesired external forces are applied. By maintaining the expansion rigidity of the core main line and weakening the bending rigidity, it is possible to achieve both the shaping function of brassieres and the like and the sense of fit to the body, and at the same time, it is possible to realize weight reduction.

Furthermore, since the outer end surfaces of the flat strip and the protrusions are selectively formed parallel to the center line in the thickness direction, quality stability and productivity can be improved even when using shape memory treatment. Moreover, even when sewn into clothing, its position is stable and it is possible to provide a product that always feels comfortable.
