Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wig in which the ends of a wig base are inconspicuous and a hair-like wire made of a shape memory alloy is used to cover the ends of the wig base. This is a wig in which the shape of the wire is formed so that the end of the wig base is not exposed even when the hair is turned up by wind or the like, and the hair can be easily set to a desired hairstyle.

[0002]

2. Description of the Related Art In a wig in which a hair material is planted on the outer surface of a wig base, it is necessary to take care and care so that the end of the wig base is not exposed, and make a hairstyle that covers the end of the base as much as possible. Is required. As a result, not only can he not choose his preferred hairstyle, but he is also unable to escape from anxiety, fearing that he will be curled up by the wind. In addition, the result is that the hair is forced into an unnatural hairstyle that hangs deeply in the front.

[0003]

[Problems to be solved] Prevent the hair material from curling up due to wind and exposing the base, and even if the hair material is curling up, the end of the base is not exposed and It relieves anxiety and reduces restrictions on the hairstyle so as not to force an unnatural hairstyle, making it possible to form a masculine hairstyle.

[0004]

[Means for solving problems]

A. Invention 1 Invention 1 solves the above-mentioned problems, and in a wig constituted by a wig base and a hair material (H) planted on the convex outer surface of the wig base, the wig base close to the wig base is provided. A large number of wire rods (F), which are planted at the edges and bent in a direction away from the end of the wig base, are arranged, and the wire rods (F) are bent into a shape approaching human skin. The wire rod (F) is made of a shape memory alloy, and the transformation temperature of the shape memory alloy is lower than the operating temperature of the wig user. It is what B. Invention 2 The invention 2 is the same as the invention 1 described above, in which the skin approaching portion is formed by a bent portion of the wire (F). C. Invention 3 According to Invention 3, in the above Invention 1, the skin-approaching portion is formed by a tip portion of a wire (F).

[0005]

[Function] Generally, a shape memory alloy is capable of arbitrarily deforming its shape at a temperature below its transformation temperature, but has a property of restoring to a memorized shape at a temperature above the transformation temperature,
Therefore, even if it is deformed, it is immediately restored and the shape cannot be freely changed by humans. This property is called "superelasticity", and on the one hand it has a troublesome difficulty of "deformation processing", but on the other hand it has an excellent restoration property and has the preferable advantage that it returns to its original shape when bent.

The present invention utilizes the shape restoring force of shape memory alloys. Therefore, there is a resistance to the strangeness of using a metal wire as a hair material, but as for the appearance of the wig, humans cannot detect that the material is a metal wire. Therefore, if the wire rod of the shape memory alloy is molded at a high temperature so that the end portion of the wig base is not exposed, the shape reverts to the high temperature molded shape in order to always restore the memorized shape at room temperature. The above-mentioned high temperature molding temperature is, for example, 350 ° C to 550 ° C, and the temperature (normal temperature) used by the user of the wig is -10 ° on a cold day and 4 on a hot day.
Assuming that the temperature is about 0 ° C, the transformation temperature of the shape memory alloy is, for example, -10 ° C or less. Therefore, at room temperature, the shape is always trying to recover. The shape-recovering ability of shape-memory alloys is incomparably stronger than that of natural and artificial hair, and according to experiments, the shape-retaining power that resists the wind and retains its shape is so strong that humans feel strange. .

[0007]

EXAMPLE 1 In FIG. 1, a wig 1 is composed of a wig base 2 and a hair material H planted on the convex outer surface of the wig base 2. A wire F is planted in the near edge portion 3 of the wig base. Hair material H
A large number of wire rods and wire rods F are planted in the base 2, but for ease of illustration, the number is reduced and drawn roughly, the wire rods F are drawn in solid lines, and the hair materials H are drawn in two-dot chain lines. Wire F
Is bent in a direction away from the end 4 of the wig base 2 in the lateral direction, and the wire F is bent in a shape to approach the human skin 6 to form a skin approaching portion 7. Although this wire F is a kind of wire, it has a color similar to the hair H, a similar gloss, and a similar appearance (thickness). If necessary, a material thinner than the hair material H may be used. If the wire is thin, it may be convenient because it reduces the ability of the human eye to discern.

The wire F is made of a shape memory alloy, and the shape memory alloy has a transformation temperature lower than the operating temperature of the wig user, for example, -10 ° C. Therefore, at room temperature, the wire F has a property of always returning to the set shape, and a person cannot freely bend it, and even if it is bent by wind or the like, it immediately returns to its original shape.

In the case of FIG. 1, the state of claim 2 (invention 2) is shown, and the skin proximity portion 7 is formed by the bent portion R of the wire F. Therefore, the end 4 of the wig base is covered with a large number of wires F, so that the end 4 is hidden and invisible. Even if the wind blows, the wire F has a stronger restoring force than the normal hair H, and therefore has a strong force to resist the wind and restores quickly.

Since human hair is different for each person, it is difficult to show only one example, but FIG. 4 is a plan view of the example and shows the left half of the human forehead.
This example is for a person without hair on the top 9 and the side 8
Has hair h. For this person, as shown in FIG. 5, the wig base 2 is covered on the hairless top portion 9. The wig base 2 has a hair material H (two-dot chain line) and a wire material F (solid line) as shown in FIG. Are planted in large numbers. FIG. 6 is drawn roughly so that the base 2 can be seen through, but in the actual product, the wire F and the hair material H are dense as shown in FIG. 7, and the end 4 of the wig base is completely invisible, It looks like the figure. In addition to the hairstyle shown in FIG. 7, various hairstyles can be tried. For example, when the wire F is roughly planted in the base 2a as shown in FIG. 8, it becomes as shown in FIG. 9, and when it is densely packed, it becomes as shown in FIG.

2 and 3, the state of claim 3 (invention 3) is shown, and the skin approaching portion 7 is formed by the tip P of the wire F. If the tip P is formed so as to come into contact with the skin 6, the wire F looks as if it has grown from the skin, and the tip P falls into the illusion that it is on the hair root side. By applying such an illusion phenomenon, various hairstyles can be tried. For example, it can be used as shown in FIG. 3 to form an artificial "green line". In any case, when the tip P is brought close to the skin as shown in FIGS. 2 and 3, even when the hair material H is turned up, the base end is hidden and the hair is not exposed.

[0012]

[Embodiment 2] An arbitrary number of wire rods F are not provided with the skin-approaching portion 7 that comes into contact with the skin. For example, as shown by reference numeral 7b in FIGS. Good. The effect is to indirectly cover and hide the base end 4 and help to hold the hairstyle near the hairline.

[0013]

[Third Embodiment] In the above description, the wire F is planted at the end of the wig base and in the vicinity thereof (referred to as the near edge 3). Besides, the wire F may be implanted, or may be mixed with the hair material H such as the crown. When expanding the area in this way, the wire F is implanted or mixed regardless of the end (or the near edge) of the wig base. Hair effect H
The overall shape retaining function can be improved. If the hairstyle holding function according to this embodiment is applied, it can also be used for a female wig.
In that case, it is possible not only to keep the set hairstyle for a long time and save the time and cost required for setting, but also to create a new hairstyle that could not be realized due to the wind.

[0014]

[Embodiment 4] If the price is high, the hair material H may be entirely replaced by the wire material F, and the hair-like portion may be entirely composed of the wire material F. In this case, the above-mentioned women's products can be used in the same manner as in the previous section [0013], and the same effect as the previous section can be obtained.

[0015]

Fifth Embodiment Since the wire F described above has a problem that it is difficult to form, it is more difficult to manufacture a wig than a conventional one. In preparation for the difficult problem of such production, an example of the production method will be shown below. This is merely an example and the present invention is not limited to this means.

[Manufacturing Method A] (1) While the wire F is cooled below the transformation temperature, the wire F is molded. (2) Next, a high temperature treatment (set) is performed at a high temperature (eg, 500 ° C). (3) Next, at room temperature, a base is prepared to form a strip-shaped base such as the base B1 shown in FIGS. 11 and 12, and a large number of wire rods f1 are arranged in parallel. Resin may be used instead of planting. The resin is preferably elastomeric and elastic. When viewed from above, the thus formed member has a comb-like shape as shown in FIG. (4) Prepare the second narrow band-shaped base B2 from the left end, and implant a large number of wire rods f2 in parallel with it or hold it with resin / elastomer. (5) Repeat for f3. Each strip-shaped base B1, B2, B3 and each wire rod f1,
Both f2 and f3 are shaped like comb teeth as shown in FIG. (6) The above steps can be completed at once. For example, the f1 row, the f2 row, and the f3 row, which are arranged in a row, are held via an appropriate spacer so that the respective rows are appropriately spaced, and the hair root portion of the group of wire rods is held. Is commonly filled with an elastomer or the like to form artificial skin.

[Manufacturing Method B] (a) As shown in FIG. 13 (a), the wire rod holding plate 10 has holes 1
It is assumed that the material has a large number of 1 and is made of a shape memory alloy, and that the shape memory alloy is restored to the memorized shape at a transformation temperature higher than normal temperature. However, at room temperature,
3 (a) is formed by plastic deformation so as to maintain the shape. (B) When the wire rod holding plate 10 is heated above the transformation temperature, it returns to the memorized shape. In this embodiment, the shape which is stored so as to be restored by heating is as shown in FIG. 13B, and the cross section taken along line XX is as shown in FIG. 13C. This shape is an example of a shape in which the wire F is set in a desired three-dimensional shape. (C) Further, the auxiliary plate 12 is, as shown in FIG.
Like the wire rod holding plate 10, it has a large number of holes 13, and its material is also formed of a shape memory alloy like the wire rod holding plate 10, and the shape memory alloy also has a high temperature at the wire rod holding plate 10.
It shall be restored to the same shape as. This is also formed by plastic deformation so as to maintain the shape as shown in FIG. 13 (d) at room temperature. Note that the needle indicated by reference numeral 14 in FIG. 14 is omitted in FIG. 13 (d). The needle 1
Reference numeral 4 denotes a needle that is erected to prevent the wire F from slipping sideways, which will be described in the next item (d). (D) As shown in an enlarged manner in FIG. 14, first, the wire F is wound around the wire holding plate 10 at room temperature, and the auxiliary plate is pressed so as to sandwich the wire. In this embodiment, two auxiliary plates 12a and 12b were used. The above-mentioned needle 14 stands on one of the 12a, and the needle is the hole 1 of the wire holding plate 10.
Penetrates 1. (E) When the wire F is wound around the wire holding plate 10 in this manner and heated as described above while being pressed by the auxiliary plate, both the wire holding plate and the auxiliary plate are deformed, for example, as shown in FIG.
As shown in (b) and (c), the three-dimensional shape of the wire F is formed. When the wire f is heated at a temperature equal to or higher than the transformation temperature of the wire f in this state, the wire f is set and its shape is stored. (F) Since the wire F is coiled when cooled to normal temperature, the wire holding plate 10 and the auxiliary plate 12 are temporarily held while temporarily holding the end 15 of the coil with, for example, an adhesive tape or a comb.
Remove a and 12b. In this way, when only one end 15 is held by an adhesive tape or the like, a coil temporarily held in a comb shape can be obtained, and both ends including the other end (not shown) can be held. In this case, a coil temporarily held in a ladder shape is obtained. If the wire rod holding plate 10 is not removed, a coil temporarily held in a core is obtained. (G) The wire F is turned around an imaginary perpendicular line to the artificial skin surface so as to be oblique to the artificial skin, for example, as shown in FIG.
Alternatively, the root of the hair may be embedded while keeping the shape of the loop, and the loop of the tip of the hair may be cut to open the tip of the hair freely.

[Manufacturing Method C] The coiled wire F obtained by the manufacturing method [B] as described above may have the roots of hair embedded in a film-like artificial skin or the like. A breathable and stretchable material can also be used. In this case, (I) An adhesive agent is previously attached to the hair root portion and brought into contact with the net or knit to adhere them. If the net and the knit side are coated with a thin adhesive beforehand, the wire F
Makes it easier to adhere to the side. The wire F may be in any state, that is, the root of the hair is left as a loop, or the loop is cut to form the tip of the wire. FIG. 16 shows an example in which a loop-shaped hair root portion 21 is adhered to the base 20 with an adhesive 27. (II) The material for forming the base may be woven or knitted with a thin wire of a shape memory alloy, or a non-woven fabric. (III) The hair root may stand against the base,
Alternatively, the hair root may be bent into an L-shape and the hair root may be brought into contact with the base surface in parallel. Such parallel contact makes adhesion even easier. FIG. 17 shows an example in which the hair root portion 22 bent into an L shape is adhered to the base 20 with an adhesive 27. Further, when the hair root portion is brought into contact with the base in parallel, the hair root portion may be joined to the base by means such as suturing without using an adhesive. (IV) Wire F uses the superelasticity of shape memory alloy,
Even so, when it is bent at an extremely sharp angle, for example, when it is pressed against a sharp 90 degree corner and bent into a sharp curve, it is plastically deformed beyond the limit of superelasticity. As a means for preventing the occurrence of such plastic deformation, it is preferable to use a flexible material, for example, as artificial skin so that the hair root portion does not come into contact with a hard corner. Therefore, even if an adhesive is used as described in (I) above, the use of an adhesive having a slight flexibility, if possible, causes the wire rod F to be plastically deformed by a sharp corner (for example, 90 degrees). It can be prevented from occurring. (V) Even with a shape memory alloy, if it bends at a steep angle beyond the limit, it plastically deforms as described above, but if this phenomenon is applied in reverse, the hairstyle can be corrected at room temperature. FIG. 18 is an example of the tool, and the cross section of the sandwiching portion YY shows an end face as shown in FIG. Although not shown in the figure, the actual corners 25, 26
Is sharply formed, and when the wire rod F is sandwiched, the wire rod is forcibly plastically deformed at the sharp corner to correct the memorized shape.

For the sake of convenience of explanation, the wire rods F, f have been described by drawing most of them in a straight line shape through the respective embodiments and drawings, but in reality, the wire rods F and f are slightly widened in the textile industry and the beauty industry. It is better to provide the crimpability (textile industry) and the wave (beauty industry), which makes the bulk look larger. As a method of forming the wavy wire F in such a manner, for example, the above-described wire rod holding plate 10 and the auxiliary plate 12 may be made to have a wavy shape memory.

Further, although the base is drawn so as to be in close contact with the scalp for convenience of explanation through the above respective embodiments and drawings, generally, a slight gap is maintained between the base and the scalp to allow ventilation. In many cases, consideration is given to things such as doing well. In the present invention, since the end of the base is not exposed, even if the space between the base and the scalp is large, it is rarely exposed. For example, as shown in FIG. 20, the base 2 supported by a side portion (not shown) of the head has a gap 30 between the scalp 9a of the top 9 of the head and the base 2, and the base is the scalp. Not in direct contact with. However, if the wire F is bent toward the skin 6 as shown in FIG. 21, the wire F is kept close to the skin 6 by the shape-recovering force of the shape memory alloy, and the base floats in the air. You won't notice it. The same parts as those in FIGS. 1 to 3 are denoted by the same reference numerals, and the description thereof is omitted.

The following reference examples depart from the claims and should be originally filed as separate applications. [Reference example] When the hairline is exposed, even when it is used as a female wig, when it is not shameful, the part bent in the direction away from the end of the base and the skin approach The part may not be provided.

[0022]

[Effects] (1) Due to the shape restoring force of the shape memory alloy called superelasticity, it has a strong force to hold and restore the hairstyle by resisting the wind, etc. Also, if the hair is turned up by the wind, it is immediately restored. (2) It eliminates the anxiety of males that the end of the wig may be exposed, and breaks away from the hairstyle peculiar to wigs, which is conventional, to form a wig with a "raw hairline" that is masculine. . (3) When used for women, it holds and restores the set hairstyle for a long time. It also allows the creation of unknown hairstyles that could not be realized due to the wind.
