Description

  The present invention relates to a wig base, and more particularly, to a wig base that is excellent in adhesiveness of a nape portion, is not easily displaced when worn, and has excellent fit.

  The main purpose of wigs is to obtain a natural appearance when worn, and it is ideal that the person wearing the wig can operate and act as if it were a normal person. However, there is a problem that the wig is shifted to an unintended position by vigorous operation.

  Conventionally, the wig base is formed according to the shape of the user's head and is attached to the head with a stopper, double-sided tape, or a special adhesive, but the wig fits so that the position does not shift. Various ideas and improvements have been made to improve the performance.

  Wigs are classified into “partial wigs” and “whole head wigs” based on the size of the wigs. However, since the head wigs are larger and heavier, there is a high possibility that they will shift when worn. Therefore, it is highly necessary to consider the fit particularly in the whole head wig.

  With respect to such a problem, in Patent Document 1 (Utility Model Registration No. 3065095), a wig base in which a V-shaped notch is formed on the side and the nape and a rubber string is installed at the entrance of the notch is used. is suggesting. Thus, the wig base makes it easy to fit the head by expanding and contracting the side head and the nape.

  However, the wig base of Patent Document 1 mainly corresponds to the fluctuation of the head circumference size due to the elongation of the hair, and there is a stretchable rubber string at the entrance of the notch, but the rubber string contracts and deforms into the notch. Even if this occurs, the two sides forming the V-shape are non-stretchable and cannot absorb deformation. Therefore, for example, the deformation of the wig base that occurs when the head is tilted back and forth cannot sufficiently follow the deformation of the wig base, causing the wig to peel off or rise.

  As a means for preventing the wig from rising, Japanese Patent Application Laid-Open No. 2007-32298 proposes a wig base in which the central region of the nape portion is covered with an elastic net.

  FIG. 4 is a diagram of a wig-based nape described in Patent Document 2. As shown in FIG. The nape part A is divided into a central part 1, a right part 2, and a left part 3, and the right part 2 and the left part 3 are substantially symmetrical. Each part is surrounded by a non-stretchable peripheral member 1a, 2a, 3a, and the inside of the peripheral member 1a of the central part 1 is covered with a stretchable net 1b. The left side portion 3 is covered with non-stretchable members 2b and 3b on both the peripheral members 2a and 3a and the inner side surrounded by them. The stretchable net 1b has a half-moon shape and expands toward the lower end.

  With the above-described configuration, the nape portion easily adheres to the roundness of the neckline, and the elastic net can be expanded and contracted following the vertical and horizontal movements of the user's head.

  However, although the wig base of the above-mentioned patent document 2 is covered with a half-moon shaped elastic net 1b in which the central portion 1 of the nape portion is expanded toward the lower end, the periphery of the wig base is made of an inelastic tape. Since it is surrounded by 1a, it cannot be deformed at all in the arrow direction (lateral direction) shown on the left and right of the figure. Further, only a slight deformation is possible in the arrow direction (vertical direction) shown in the upper and lower parts of the figure, and the area of the net 1b is small, so that the amount of deformation is small. Therefore, sufficient follow-up to the deformation of the nape portion cannot be performed, and there is a possibility that deviation or lifting will occur.

  As shown in this example, it is an effective method to cover the nape portion with the elastic net 1b. However, in order to obtain the necessary elastic force in the required direction, one elastic net 1b is used. This cannot be achieved with a structure that stretches all over.

Utility model registration No. 3065095 JP2007-32298A

  An object of the present invention is to provide a wig base in which the nape portion of the wig base does not rise or shift even when the head is moved back and forth and left and right. is there.

  In order to achieve the above object, the wig base of the present invention is a wig base in which the periphery of the nape portion is surrounded by a peripheral member, and the peripheral member has a bottom portion extending in the lateral direction at the lower end of the nape portion, One or more elastic pieces stretchable in the vertical direction are installed on the inner side surrounded by the peripheral member, and the base part has elasticity, and the vertical elastic coefficient and the horizontal elastic coefficient of the nape part are different. It is characterized by that.

  The nape part is divided into a central part and left and right side parts, the bottom part is the bottom part of the central part, and the elastic piece is in the central part. It is configured to be integrally molded, or a plurality of elastic pieces that are stretchable in the vertical direction are configured to be separated from each other, or the peripheral member surrounds the upper edge of the nape portion. And the upper side portion can also be stretchable.

  According to the present invention, since the bottom part of the peripheral member has elasticity, the peripheral member of the nape part can be deformed even if the wig base is deformed by shaking the head (neck) back and forth after mounting the wig. In particular, the base portion of the base can be expanded and contracted to sufficiently follow the deformation of the nape portion. Therefore, it is possible to obtain a wig base excellent in fit without causing the wig to shift or float.

  Further, by making the elastic coefficients different from each other in the vertical direction and in the horizontal direction, it can be expanded and contracted in the required direction as much as necessary, and the fitting property is further improved.

It is a perspective view which shows the state which mounted | worn the wig base of this invention to the head, (a) is the state which straightened the head, (b) is the state which inclined the head ahead, (c) is the head. It is each perspective view which shows the state inclined backward. It is a figure of the nape part of the wig base of this invention, (a) is a figure when a head is inclined ahead, (b) is a figure which shows the state which inclined the head back. FIG. 6 is a view showing another embodiment of the wig base of the present invention, in which (a) is an embodiment in which the peripheral member on the upper side of the central portion is a stretchable member, and further, elastic pieces are provided in a lattice shape; These are the Example by which the non-expandable member of the left side head part and the right side head part is integrally molded. It is a figure of the nape part of the conventional wig base.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a state in which the wig base 10 of the present invention is mounted on the head, where (a) is a state in which the head is straightened, (b) is a state in which the head is tilted forward, (c ) Is a perspective view showing a state in which the head is tilted rearward. 2A and 2B are views of the nape portion of the wig base according to the present invention. FIG. 2A is a diagram when the head is tilted forward, and FIG. 2B is a diagram illustrating a state where the head is tilted rearward. . In the present invention, the cross-hatched portion of FIG. 2 is used as an elastic member.

  The wig base 10 of the present invention is made in accordance with the three-dimensional shape of the wearer's head, and uses a net-like fiber material, artificial skin using polyurethane, silicon, or the like. However, the material is not particularly limited. At the lower end of the back of the wig base 10 is a nape 11. As shown in FIG. 2, the nape portion 11 is divided into a left head portion 12, a right head portion 13, and a central portion 14. The left side head 12 and the right side head 13 are substantially symmetrical.

  The central portion 14 is surrounded by a peripheral member 14a on the upper side, a peripheral member 14b on the left side, a peripheral member 14c on the right side, and a peripheral member 14d on the lower side in the lateral direction. In this example, the peripheral members 14 b and 14 c surround the left and right sides of the central portion 14 and also surround the three sides of the left head portion 12 and the right head portion 13, but the left head portion other than the boundary with the central portion 14. The part surrounding 12 and the right side head 13 may be another peripheral member. The upper side 12 a of the left head portion 12, the upper side 13 a of the right head portion 13, and the peripheral member 14 a on the upper side of the central portion are portions connected to the portion that becomes the main body of the wig base 10. Elastic pieces 15 made of a plurality of stretchable tapes are erected apart from each other in the longitudinal direction inside the central portion 14 surrounded by the peripheral member.

  The movement of the head includes the movement of tilting the head in the front-rear and left-right directions and the twisting in the left-right direction when moving the line of sight to the left and right. It is an exercise to defeat. If it is possible to follow the deformation of the nape due to this movement, it is considered that the deformation of the nape due to other movements can be sufficiently handled.

  FIGS. 1B and 1C are views showing a state where the head is tilted in the front-rear direction. As shown in FIG. 1B, when the head equipped with the wig base 10 is tilted forward, the left head 12 is pulled obliquely in the upper left direction as shown by the arrow in FIG. On the other hand, the right head 13 is pulled obliquely in the upper right direction as shown by the arrow in the figure. The central portion 14 of the nape portion 11 is pulled left and right, and pulled upward as shown by a broken line as a whole. Then, the peripheral member 14d surrounding the lower side of the central portion 14 is pulled downward, and the peripheral member 14d is greatly curved downward in an arcuate shape. That is, in FIG. 2A, since the peripheral member 14d which is the bottom of the central portion 14 is made of a stretchable member, it can be sufficiently deformed by bending downward in a large arc shape in accordance with this force. It is possible to prevent wig-based displacement and lifting.

  As shown in FIG. 2A, a plurality of elastic pieces 15 made of a stretchable tape are installed in the center portion 14 so as to be separated from each other. These elastic pieces 15 can be extended and deformed due to the stretchability of the peripheral member 14d as it is bent and deformed downward in a large bow shape.

  As shown in FIG. 1 (c), when the head mounted with the wig base 10 is tilted rearward, the peripheral member 14d surrounding the lower side of the central portion 14 is subjected to a force that pushes upward. As shown in FIG. 2B, the left head portion 12 is pushed down obliquely in the lower right direction as shown by the arrow in the figure. On the other hand, the right side head 13 is pushed down diagonally to the lower left as shown by the arrow in the figure. A tensile force is applied to the upper peripheral member 14a and acts to push down the nape portion 11 as a whole. As a result, the peripheral member 14d on the lower side is greatly curved upward. At this time, the elastic piece 15 is contracted because a contracting force is applied.

  In the present invention, since the peripheral member 14d and the elastic piece 15 are separate members, the elastic coefficient of the peripheral member 14d and the elastic coefficient of the elastic piece 15 can be the same, or different elastic coefficients. It is. Further, since the plurality of elastic pieces 15 are spaced apart from each other, the elastic pieces 15 have no resistance to lateral elongation.

  In general, by the operation of tilting the head back and forth, in the nape portion 11, the vertical expansion and contraction is large, and the horizontal expansion and contraction (expansion and contraction due to the bending of the peripheral member 14 d) is smaller than the vertical direction. If the elastic modulus in the longitudinal direction, which is the longitudinal direction of the peripheral member 14d, is made easier to extend and the elastic modulus in the lateral direction, which is the longitudinal direction of the peripheral member 14d, is made larger than that in the longitudinal direction, the followability is improved.

  3A and 3B show another embodiment of the present invention. In the embodiment shown in (a), not only the peripheral member 14d at the bottom of the central portion 14 but also the peripheral member 14a at the upper side is made of a stretchable member, and an elastic piece 16 that intersects the elastic piece 15 is provided. It has become. With this configuration, the entire central portion 14 can be expanded and contracted in both the vertical and horizontal directions, and in particular, the expansion and contraction force in the horizontal direction can be improved. In addition, since the elastic pieces 15 and the elastic pieces 16 are arranged in a lattice shape, a large number of elastic pieces are used, and it is possible to cope with fine expansion and contraction. In this case, the elastic coefficients of the elastic piece 15 and the elastic piece 16 can be the same or different.

The embodiment shown in FIG. 3B is an example in which the non-expandable members of the left head portion 12 and the right head portion 13 are integrally formed. That is, the peripheral members 12a, 13a, 14a, 14b, and 14c are continuous. The area to be expanded / contracted, that is, the bottom side of the central portion 14 may not be surrounded by the non-expandable member.

  In the above embodiment, the nape part 11 is divided into three parts, that is, the left head part 12, the right head part 13 and the central part 14, but the central part is extended to the left and right so that these three parts are integrated. You may make it give a stretching property to the whole part.

  The elastic member such as the peripheral member 14d on the bottom side and the elastic piece 15 is not particularly limited as long as it is a material having elasticity. For example, a stretch material such as rubber or spandex, or a material having an elastic structure such as a spring may be used.
