Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wig, and particularly to a wig having a shape holding member for preventing the wig base from curling up or being distorted.

[Conventional technology and problems]

Conventionally, in order to prevent the wig base from curling up or becoming distorted, a method of fixing the scalp or hair to the inner surface of the wig base with adhesive 1 double-sided tape has been widely adopted.
With this method, it is very troublesome to put on and take off the wig, and it is also uncomfortable when using it, and especially when double-sided tape is used, its adhesive strength weakens after putting on and taking off the wig several times. , the double-sided tape had to be replaced frequently.

For this reason, a mold holding member made of a metal wire such as wire or a metal plate is placed along the curved shape of the wig base in areas where curling is likely to occur, such as the forehead, sideburns, and nape. The wig base is fitted to the shape of the user's head by manually bending this mold holding member when putting on the wig.

However, in a wig equipped with such a type holding member, in order to ensure that the type holding member curves outward and inward when putting on and taking off the wig, the core layer holding member has a wavy shape as it is deformed and used. It begins to transform into
By arranging the shape holding member in such a wavy shape on the wig base, the fit of the wig is adversely affected, and the shape holding member deforms during use, resulting in damage to the wig, for example. There was a problem in that the tips of the sideburns, forehead, nape, etc., were raised.

[Purpose of the invention]

In view of the above points, the present invention has been developed to prevent the mold holding member from deforming into a wavy shape even after repeated use. The purpose of the present invention is to provide a wig that does not become loose or lift up and can always maintain a good fit over a long period of time.

[Means and actions for solving the problem] The above purpose is:
According to the present invention, in a wig formed by planting a large number of hairs on the convex outer surface of a wig base made of artificial skin or net, any position of the concave inner surface or convex outer surface of the wig base can be set. At least one of the mold holding members disposed along the curved shape of the wig base is heated to a temperature lower than the body temperature of the user's head, for example, about -10°C to 38°C, preferably about 24°C to 36°C. This is achieved by being made of a shape memory alloy which has a transformation temperature of 0.degree. C. and whose memory shape is a curved shape corresponding to the curved shape of the wig base.

According to this invention, as a mold holding member for a wig base,
Since a shape-retaining member made of a shape memory alloy is used, when the wig is worn on the user's head, the shape-retaining member will be heated above its transformation temperature by the body temperature of the user's head. As a result, it is restored to a curved shape corresponding to the curved shape of the wig base, which has a memory shape, and this state is maintained while it is being worn, so when wearing the wig, the shape is maintained especially according to the shape of the user's head. The core layer holding member itself fits snugly into the curved shape of the wig base, which is made to match the shape of the user's head, without curving the member, making it possible to fit the wig base to the shape of the user's head. Furthermore, the mold holding member does not deform into a wavy shape due to repeated use, and it is possible to wear the wig in the same state without manually bending the mold holding member into the appropriate shape. You can easily get a good fit.

〔Example〕

Hereinafter, the present invention will be explained in more detail based on one embodiment shown in the drawings.

FIG. 1 shows an embodiment of the wig according to the present invention, and the wig 10 basically includes a wig base 11 formed to correspond to the shape of the user's head, and a large number of wigs on the outer surface of the wig base 11. Hair consisting of implanted hair and/or artificial hair (
(not shown).

The illustrated wig 10 is formed as a full wig having a wig base 11 having an outer shape along the hairline so as to cover the entire head including the hairline. The material of the wig base 11 may be one mainly made of artificial skin made of soft synthetic resin or one mainly made of net.

For example, in the sideburns 11a of the wig base 11,
A mold holding member 12 is provided to prevent the sideburns 11a from lifting, curling up, distortion, etc. The mold holding member 12 may be attached to the sideburns 11a of the wig base 11 on either the convex outer surface or the concave inner surface of the wig base 11.
It is fixed by appropriate means such as adhesion.

The mold holding member 12 has a temperature lower than the body temperature of the user's head, for example, about -10°C to 38°C, particularly 24°C to 36°C.
The wig base 11 is made of a shape memory alloy having a transformation temperature (Af point) of 0.degree. C., and its memory shape is, for example, as shown in FIG. is stored in a shape that matches the curved shape of.

Here, the shape memory alloy that can be applied to the present invention is an alloy that once memorizes a certain shape through memory heat treatment, and can be restored to the memorized shape by just heating it appropriately even if it is deformed. For example, without limitation, Cu-
Copper-based alloys such as Zn-Al, Ni-Ti alloys commercially available as shape memory NT gold alloys (manufactured by Furukawa Electric), etc. can be suitably used. This shape memory processing is usually 400~
This is done by heat treatment at 500''C for 10-30 minutes.

In the present invention, the shape memory alloy as described above is made into a wire or thin plate shape, for example, a wire rod having a cross-sectional shape of 0.1 to 2 m in diameter, or a wire rod with a wart width of 2 to 10 cm and a thickness of 0.2 to 21 cm. It is preferable to use a thin plate with a rectangular cross section. In any case, if the cross section is too thick, the wig base will become thicker, which is not preferable.

The wig according to the present invention is constructed as described above, and when the present wig is to be worn on the user's head, the wig 10 is first placed at a predetermined position on the user's head, and the wig base 12 is placed around the wig base 12. It is attached using a fixing member (not shown) provided in the holder, adhesive, or the like. If left in this state for a while, the shape memory alloy constituting the mold holding member 12 will be heated to the Af point or higher due to the body temperature of the user's head, and therefore the core layer holding member 12 will lose its shape. Since it is restored to a curved shape corresponding to the curved shape of the wig base, which is the memory shape of the memory alloy, the tip of the sideburns 11a of the wig base 11 fits into the user's sideburns according to the memorized shape.

Therefore, even if the mold holding member 2 is deformed during storage of the wig 10, there is no need to modify the shape of the mold holding member 12. IO will be fitted. Also, while the wig 10 is in use, the mold holding member 12 attached to the wig base 11 is always maintained at a temperature above the transformation temperature, so no external force is applied. Even if the wig base 11 is deformed into a shape that deviates from the curved shape due to
There is no such thing as a turning up.

In the above embodiments, the case where the mold holding member 12 made of a shape memory alloy is provided on the sideburns 11a of the wig base 11 constituting the wig 10 has been described, but this is not limited to this. For example, as shown in FIGS. 3 to 7, along the lower edge of the nave portion of the wig base 11 constituting the wig 10 (FIG. 3) ,
Along the center of the back of the head (Figure 4), connecting the tops of the ears on both sides in a nearly horizontal direction (Figure 5), and in parallel from the front of the head to the top of the head (Figure 6), and then the tops of the ears on both sides. Shape memory alloy wires of any size and number are tied horizontally and extend downward from the central part of the back of the head to the nape part (Fig. 7) at any position on the inner or outer surface of the wig base 11. It is possible to attach the mold holding member 12 freely. Further, when attaching the mold holding member 12, for example, in order to avoid direct contact with the scalp, the nuclear layer holding member may be sewn or glued while being housed in a bag made of cloth or net. , there are no particular restrictions.

Furthermore, although each side above is shown for the case of a full wig, it is clear that exactly the same effect can be obtained in the case of a partial wig.

〔Effect of the invention〕

As described above, according to the present invention, in a wig formed by planting a large number of hairs on the convex outer surface of a wig base made of artificial skin or net, the concave inner surface or convex surface of the wig base At least one of the mold holding members disposed along the curved shape of the wig base at any position on the outer surface has a temperature lower than the body temperature of the user's head, for example, about -10°C to 38°C1, preferably about 24℃～36℃
Since the wig is made of a shape memory alloy that has a transformation temperature of , the mold holding member is heated above the metamorphosis temperature by the body temperature of the user's head, and as a result, it is restored to the curved shape corresponding to the curved shape of the wig base, which is a memorized shape, so when wearing the wig, In particular, without curving the mold holding member to suit the shape of the user's head, the nuclear layer holding member itself naturally extends to the curved shape of the wig base made to match the shape of the user's head.
They fit snugly and can be maintained that way during their wearing.

Therefore, even after repeated use of this wig, the shape holding member does not deform into a wavy shape, and the wig can be worn without manually bending the shape holding member into an appropriate shape. It is possible to achieve a good fit very easily.

Thus, according to the present invention, the mold holding member does not deform into a wavy shape even after repeated use, and furthermore, the mold holding member does not deform during use and the wig base does not curl up or lift off from the user's head. Therefore, it is possible to provide an extremely excellent wig that does not cause any wear and tear, and therefore provides a constant wig fit over a long period of time.
