- the reversing member 4 has a substantially quadrilateral planar shape including a long side portion 4 a , another long side portion 4 b facing the long side portion 4 a , and two facing short side portions 4 c and 4 d 1 /d 2 .
- the short side portion 4 d 1 /d 2 on the left side of the figure the short side portion 4 d 1 and the short side portion 4 d 2 are apart from each other, and it can also be said that the reversing member 4 in the initial state has a substantially C-shaped planar shape.
- a coupling hole 22 a and a coupling hole 22 b are provided near the end portions of the short side portion 4 d 1 and the short side portion 4 d 2 across the separated space.
- a center-to-center distance between the coupling hole 22 a and the coupling hole 22 b is indicated by D.
- the long side portion 4 a is attached with a plurality of comb teeth 10 and 12 each connected to the long side portion 4 a at one end (see an arrow A in FIG. 1 ), and each having a free end at the other end (see an arrow B in FIG. 1 ). More specifically describing the comb teeth 10 and 12 , they have the first comb tooth 10 and the second comb tooth 12 having different lengths from one end to the other end. The first comb tooth 10 is formed longer than the second comb tooth 12 .
- the first comb tooth 10 includes a shaft portion 10 a and a substantially spherical head portion 10 b provided at a free end of the shaft portion 10 a .
- the second comb tooth 12 includes a shaft portion 12 a and a substantially spherical head portion 12 b provided at a free end of the shaft portion 12 a .
- the first comb tooth 10 and the second comb tooth 12 are formed of a metal material, and are attached to the long side portion 4 a of the reversing member 4 by welding or brazing, for example.
- the first comb tooth 10 and the second comb tooth 12 extend in a direction substantially orthogonal to the longitudinal direction of the long side portion 4 a of the reversing member 4 .
- the first comb tooth 10 and the second comb tooth 12 are not always necessary to be orthogonal to the longitudinal direction of the long side portion 4 a , and may extend in a direction obliquely inclined with respect to the longitudinal direction of the long side portion 4 a .
- the first comb tooth 10 and the second comb tooth 12 are preferably disposed substantially parallel to each other.

- 0.15 to 2 mm can be exemplified as the thickness
- 20 to 50 mm can be exemplified as the length on the long side portion side (see W in FIGS. 1 )
- 6 to 30 mm can be exemplified as the length on the short side portion side.
- 8 to 30 mm can be exemplified as the length of the comb teeth 10 and 12
- 0.3 to 2 mm can be exemplified as the outer diameter of the shaft portions 10 a and 12 a of the comb teeth 10 and 12 .
- 1 to 3 mm can be exemplified as the interval between adjacent comb teeth 10 and 12 .
- these dimensions are exemplary when applied to the wig, and any other dimension can be adopted according to the application.
- the reversing member 4 is deformed so that the coupling hole 22 a and the coupling hole 22 b having had the center-to-center distance D overlap with each other, and is fastened by the coupling member 20 , whereby the fastener 2 as shown in FIG. 2 can be formed.
- the long side portion 4 a and the other long side portion 4 b facing each other are curved so that the central region in the longitudinal direction protrudes.
- the coupling member 20 For example, with a metal rivet as the coupling member 20 , the rivet is inserted and then the inserted tip portion is plastically deformed, so that the coupling can be made. That is, “swaging” enables coupling.
- the coupling method is not limited thereto, and for example, mechanical coupling can be made using other coupling members such as a bolt and a nut, or coupling can be made by welding.
- the use of the coupling member 20 is more excellent in operability because there is a margin for the overlapped coupling regions to relatively move.
- the reversing member 4 of the fastener 2 formed as described above has a substantially rectangular planar shape including four sides. As shown in FIG. 3 A , in the long side portion 4 a and the other long side portion 4 b facing each other, when the central region in the longitudinal direction is curved so as to protrude downward in the figure, the first comb tooth 10 and the second comb tooth 12 come close to the reversing member 4 , and the state is maintained by the elastic force of the reversing member 4 . That is, the state in which the first comb tooth 10 and the second comb tooth 12 are closed is maintained by the elastic force of reversing member 4 .
- the user's hair is scooped up by the first and second comb teeth 10 and 12 , a predetermined amount of hair is inserted between the first and second comb teeth 10 and 12 and the reversing member 4 , and then the reversing member 4 is reversed, and the first and second comb teeth 10 and 12 are changed from an opened state to a closed state, whereby the predetermined amount of hair can be sandwiched between the first and second comb teeth 10 and 12 and the reversing member 4 to be held.
- the reversing member 4 of the fastener 2 has a substantially rectangular planar shape, a state in which the first and second comb teeth 10 and 12 are opened and a state in which the first and second comb teeth 10 and 12 are closed can be stably maintained, and opening and closing of the first and second comb teeth 10 and 12 can be changed by easily reversing the reversing member 4 .
- a friction member 6 is provided on the entire surface of the other long side portion 4 b of the reversing member 4 .
- an elastic material having a high friction coefficient such as rubber including silicon, elastomer, or urethane can be used.
- the friction member formed in a tubular shape 6 is inserted from the separation region (see FIG. 1 ) of the reversing member 4 , attached so as to cover the other long side portion 4 b , and then the reversing member 4 is deformed and coupled, whereby the other long side portion 4 b of the reversing member 4 can be provided with the friction member 6 .
- the present invention is not limited thereto, and after the reversing member 4 is deformed and coupled, the friction member 6 can also be attached to the other long side portion 4 b by adhesion or the like.
- the force of holding the hair between the first and second comb teeth 10 and 12 and the friction member 6 can increase in a state where the first and second comb teeth 10 and 12 are closed, and the fastener 2 can be more reliably fixed to the hair.
- the reversing member 4 is provided with a total of five attaching holes 24 including two attaching holes on the left side and three attaching holes on the right side in the figure. Furthermore, a central portion of the coupling member 20 is also opened, and substantially three attaching holes on each of the left and right sides are provided.
- the fastener 2 can be sewn onto the wig base, with a sewing thread or the like passing through the attaching hole 24 or the like.
- the attaching hole 24 reduces the weight of the fastener 2 , and makes the reversing member 4 easily deformed.
- the long side portion 4 a and the other long side portion 4 b are curved.
- the larger the center-to-center distance D between the coupling holes 22 a and 22 b is than the length W (see FIG. 1 ) in the longitudinal direction of the long side portion 4 a the more greatly the reversing member 4 is deformed, and the degree of curvature of the long side portion 4 a and the other long side portion 4 b can be increased.
- the opening angle formed by the first and second comb teeth 10 and 12 and the reversing member 4 can be made larger in a state where the first and second comb teeth 10 and 12 are opened. Therefore, since the hair can be inserted to the vicinity of the root portion where the first and second comb teeth 10 and 12 are fixed to the reversing member 4 , more hair can be inserted.
- the opening angles of the comb teeth 10 and 12 in the opened state are large, the distance between the tips of the first and second comb teeth 10 and 12 and the reversing member 4 can be increased. Accordingly, hair can be easily inserted between the opened first and second comb teeth 10 and 12 and the reversing member 4 .
- the distance between the tips of the first and second comb teeth 10 and 12 and the reversing member 4 can be sufficiently increased.
- the length of first comb tooth 10 is about 12 mm
- a distance of about 6 mm can be taken between the tip of the first comb tooth 10 and the reversing member 4 in the opened state.
- the fastener 2 includes the first comb tooth 10 and the second comb tooth 12 having different lengths from one end (see arrow A in FIG. 1 ) to the other end (see arrow B in FIG. 1 ), and the first comb tooth 10 and the second comb tooth 12 are disposed adjacent to each other in the longitudinal direction of the long side portion 4 a of the reversing member 4 .
- human hair grows in multiple stages, is quite voluminous, has different lengths, and has different hair streams.
- the fastener 2 In order to sandwich the user's hair in the fastener 2 to fix the fastener 2 to the hair, it is necessary to insert the hair between the first and second comb teeth 10 and 12 in the opened state and the reversing member 4 .
- the hair escaping and failing to be scooped up when hair is attempted to be scooped up by the first comb tooth 10 having a longer length can be scooped up by the adjacent second comb tooth 12 having a smaller length. Accordingly, more hair can be easily put into between the first and second comb teeth 10 and 12 and the reversing member 4 .
- the hair when the hair is sandwiched between the comb teeth 10 and 12 and the reversing member 4 , the hair is oriented not only in the extending direction of the comb teeth 10 and 12 but also in a direction oblique to the extending direction of the comb teeth.
- the sandwiched hair is entangled with the comb teeth 10 and 12 at various angles, a force of sandwiching and fixing the hair with the fastener 2 can be increased. Therefore, the fastener 2 can be firmly and stably fixed to the user's hair.
- a fastener 2 capable of switching between a state in which the comb teeth are closed and a state in which the comb teeth are opened by reversing the reversing member 4 , the fastener 2 capable of easily sandwiching more hair between the comb teeth 10 and 12 and the reversing member 4 , the fastener 2 capable of being firmly and stably fixed to the user's hair.
- a first comb teeth region 10 A including two first comb teeth 10 arranged adjacent to each other and a second comb teeth region 12 A including two second comb teeth 12 arranged adjacent to each other are arranged adjacent to each other.
- the first comb teeth region 10 A and second comb teeth region 12 A respectively including a plurality of comb teeth 10 and 12 arranged adjacent to each other allow the hair to be more reliably scooped up, and allow the hair having not been scooped up in the first comb teeth region 10 A to be reliably scooped up in the adjacent second comb teeth region 12 A having a shorter length.
- the present embodiment has an arrangement pattern in which the first comb teeth region 10 A and the second comb teeth region 12 A are alternately arranged in the longitudinal direction of the long side portion 4 a of the reversing member 4 .
- the first comb teeth region 10 A, the second comb teeth region 12 A, the first comb teeth region 10 A, the second comb teeth region 12 A, and the first comb teeth region 10 A are arranged in this order.
- the hair can be reliably sandwiched between the comb teeth 10 and 12 and the reversing member 4 in substantially the entire region in the longitudinal direction of the long side portion 4 a of the reversing member 4 .
- the first comb tooth 10 and the second comb tooth 12 are arranged bilaterally symmetrically with respect to the central portion in the longitudinal direction of the long side portion 4 a of the reversing member 4 .
- This symmetrical arrangement allows the hair to be sandwiched in a well-balanced manner between the comb teeth 10 and 12 and the reversing member 4 , and thus fixation in which the fastener 2 is less likely to be displaced from the hair can be achieved.
- the free ends of the first and second comb teeth 10 and 12 are provided with substantially spherical head portions 10 b and 12 b , and the head portions 10 b and 12 b are positioned outside the substantially quadrilateral planar shape of the reversing member 4 . Accordingly, it is possible to cause the first and second comb teeth 10 and 12 to easily scoop up the user's hair. On the other hand, when the first and second comb teeth 10 and 12 extend too long, the head portions 10 b and 12 b are more likely to be caught in the net of the wig when the fastener 2 is attached to the wig base.
- the fastener 2 since the fastener 2 can be firmly fixed to the user's hair, in the substantially quadrilateral planar shape of the reversing member 4 , even when the lengths of the two facing short side portions 4 c and 4 d 1 /d 2 are shortened, a sufficient force of fixing can be obtained. Therefore, even when the head portions 10 b and 12 b of the first and second comb teeth 10 and 12 are positioned outside the substantially quadrilateral planar shape of the reversing member 4 , the first and second comb teeth 10 and 12 do not extend too long. Accordingly, it is possible to provide a fastener 2 making it easy to scoop up the user's hair and less likely to be caught in the net of the wig.
- the arrangement of the comb teeth having different lengths is not limited to the first embodiment, and any other arrangement of comb teeth can be adopted as long as the first comb tooth 10 and the second comb tooth 12 having at least different lengths are provided, and the first comb tooth 10 and the second comb tooth 12 are arranged adjacent to each other in the longitudinal direction of the long side portion 4 a of the reversing member 4 .
- a fastener according to second to fourth embodiments of the present invention will be described below with reference to FIGS. 4 A to 4 C .
- FIG. 4 A is a plan view schematically showing a region of comb teeth of a fastener according to a second embodiment of the present invention.
- a first comb teeth region 10 A including one first comb tooth 10 and a second comb teeth region 12 A including one second comb tooth 12 shorter than the first comb tooth 10 are arranged adjacent to each other.
- the first and second comb teeth regions 10 A and 12 A respectively include a plurality of first and second comb teeth 10 and 12 arranged adjacent to each other, but in the present embodiment, it is different in that the first and second comb teeth regions 10 A and 12 A respectively include one first and second comb teeth 10 and 12 .
- first and second comb teeth regions 10 A and 12 A respectively include one first and second comb teeth 10 and 12 , even when the length of the long side portions 4 a of the reversing member 4 are the same, it is possible to increase the number of states in which comb teeth having different lengths are adjacent to each other. Accordingly, a function of scooping up hair that has not been scooped up by the first comb tooth 10 with the adjacent second comb tooth 12 having a smaller length can be more effectively exhibited.
- FIG. 4 B is a plan view schematically showing a region of comb teeth of a fastener according to a third embodiment of the present invention.
- a first comb teeth region 10 A including two first comb teeth 10 arranged adjacent to each other and a second comb teeth region 12 A including one second comb tooth 12 shorter than the first comb tooth 10 are arranged adjacent to each other.
- the first and second comb teeth regions 10 A and 12 A respectively include the same number of first and second comb teeth 10 and 12 arranged adjacent to each other, but in the present embodiment, it is different in that the first and second comb teeth regions 10 A and 12 A include the different number of first and second comb teeth 10 and 12 .
- an arrangement pattern is provided in which the first comb teeth region 10 A and the second comb teeth region 12 A are alternately arranged in the longitudinal direction of the long side portion 4 a of the reversing member 4 .
- the second comb teeth region 12 A, the first comb teeth region 10 A, the second comb teeth region 12 A, the first comb teeth region 10 A, the second comb teeth region 12 A, the first comb teeth region 10 A, and the second comb teeth region 12 A are arranged in this order.
- the first comb tooth 10 and the second comb tooth 12 are arranged bilaterally symmetrically with respect to the central portion in the longitudinal direction of the long side portion 4 a of the reversing member 4 .
- FIG. 4 C is a plan view schematically showing a region of comb teeth of a fastener according to a fourth embodiment of the present invention.
- the fastener 2 according to the present embodiment in the longitudinal direction of the long side portion 4 a of the reversing member 4 , it is different from the first embodiment in that a third comb teeth region 14 A including one third comb tooth 14 shorter than the second comb tooth 12 is provided, in addition to a first comb teeth region 10 A including two first comb teeth 10 arranged adjacent to each other and a second comb teeth region 12 A including one second comb tooth 12 shorter than the first comb tooth 10 .
- first comb tooth 10 the second comb tooth 12 , and the third comb tooth 14 are arranged bilaterally symmetrically with respect to the central portion.
- the third comb tooth 14 shorter than the second comb tooth 12 is disposed adjacent to the second comb tooth 12 , hair that has not been scooped up by the first comb tooth 10 can be scooped up by the adjacent second comb tooth 12 having a smaller length, and furthermore, hair that has not been scooped up by the second comb tooth 12 can be scooped up by the adjacent third comb tooth 14 having a still smaller length.

- In the fastener for a wig described in
Patent Literature 1, the plurality of comb teeth attached to the reversing member are formed to have the same length. In general, human hair grows in multiple stages, is quite voluminous, has different lengths, and has different hair streams. For this reason, when the lengths of the comb teeth are the same, the tips of the comb teeth are aligned in a straight line. Therefore, when the tips of the comb teeth touch the hair, the hair streams deviate, and the hair escapes, so that it is difficult to scoop up a sufficient amount of hair. - In addition, when the tips of the comb teeth are aligned in a straight line, the sandwiched hair tends to be oriented along the extending direction of the comb teeth, and there is a possibility that the fastener cannot be fixed with a sufficient force.
- An object of the present invention is to solve the above problems, and an object of the present invention is to provide a fastener capable of switching between a state in which comb teeth are closed and a state in which comb teeth are opened by reversing a reversing member, the fastener capable of sandwiching more user's hair and of being firmly fixed to the user's hair.
- In order to solve the above problems, a fastener according to the present invention includes: a reversing member having a long side portion curved so that a central region in a longitudinal direction protrudes, the reversing member made of an elastic material; and a plurality of comb teeth, each of the plurality of comb teeth connected at one end to the long side portion, another end of each of the plurality of comb teeth being a free end, the plurality of comb teeth extending in a direction intersecting the longitudinal direction of the long side portion, the plurality of comb teeth arranged at predetermined intervals along the longitudinal direction of the long side portion. The plurality of comb teeth include a first comb tooth and a second comb tooth at least having different lengths from the one end to the other end, and the first comb tooth and the second comb tooth are disposed adjacent to each other in the longitudinal direction of the long side portion. The plurality of comb teeth are changed to a state of being in proximity to and a state of being apart from the reversing member by reversing of the reversing member.
- As described above, the present invention can provide a fastener capable of switching between a state in which comb teeth are closed and a state in which comb teeth are opened by reversing a reversing member, the fastener capable of sandwiching more user's hair and of being firmly fixed to the user's hair.

- First, a fastener according to a first embodiment of the present invention will be described with reference to
FIGS. 1, 2, 3A, and 3B .FIG. 1 is a plan view schematically showing a reversing member constituting a fastener according to a first embodiment of the present invention.FIG. 2 is a plan view schematically showing a fastener according to the first embodiment of the present invention.FIG. 3A is a side view as viewed from an arrow C inFIG. 2 , and particularly, a view showing a state in which comb teeth are closed.FIG. 3B is a side view as viewed from an arrow C inFIG. 2 , and particularly, a view showing a state in which comb teeth are opened. -
FIG. 1 shows a planar shape of the reversingmember 4 in an initial state before deformation. The reversingmember 4 according to the present embodiment is formed of a metal thin plate being an elastic material. However, the material is not limited thereto, and any other material including a resin material can be used as long as the material has elasticity. In the initial state, the reversingmember 4 has a substantially quadrilateral planar shape including along side portion 4 a, anotherlong side portion 4 b facing thelong side portion 4 a, and two facingshort side portions 4 c and 4d 1/d2. - In the short side portion 4
d 1/d2 on the left side of the figure, the short side portion 4d 1 and the short side portion 4d 2 are apart from each other, and it can also be said that the reversingmember 4 in the initial state has a substantially C-shaped planar shape. Acoupling hole 22 a and acoupling hole 22 b are provided near the end portions of the short side portion 4d 1 and the short side portion 4d 2 across the separated space. A center-to-center distance between thecoupling hole 22 a and thecoupling hole 22 b is indicated by D. - The
long side portion 4 a is attached with a plurality ofcomb teeth long side portion 4 a at one end (see an arrow A inFIG. 1 ), and each having a free end at the other end (see an arrow B inFIG. 1 ). More specifically describing thecomb teeth first comb tooth 10 and thesecond comb tooth 12 having different lengths from one end to the other end. Thefirst comb tooth 10 is formed longer than thesecond comb tooth 12. - The
first comb tooth 10 includes ashaft portion 10 a and a substantiallyspherical head portion 10 b provided at a free end of theshaft portion 10 a. Similarly, thesecond comb tooth 12 includes ashaft portion 12 a and a substantiallyspherical head portion 12 b provided at a free end of theshaft portion 12 a. Thefirst comb tooth 10 and thesecond comb tooth 12 are formed of a metal material, and are attached to thelong side portion 4 a of the reversingmember 4 by welding or brazing, for example. - The
first comb tooth 10 and thesecond comb tooth 12 extend in a direction substantially orthogonal to the longitudinal direction of thelong side portion 4 a of the reversingmember 4. However, thefirst comb tooth 10 and thesecond comb tooth 12 are not always necessary to be orthogonal to the longitudinal direction of thelong side portion 4 a, and may extend in a direction obliquely inclined with respect to the longitudinal direction of thelong side portion 4 a. However, thefirst comb tooth 10 and thesecond comb tooth 12 are preferably disposed substantially parallel to each other. - To summarize the above description, it can be said that the
first comb tooth 10 and thesecond comb tooth 12 extend in a direction intersecting the longitudinal direction of thelong side portion 4 a of the reversingmember 4. Thefirst comb tooth 10 and thesecond comb tooth 12 are arranged at predetermined intervals along the longitudinal direction of thelong side portion 4 a of the reversingmember 4. - The reversing
member 4, thefirst comb tooth 10, and thesecond comb tooth 12 can be formed of a metal material such as stainless steel, carbon steel, aluminum, copper, or titanium. Furthermore, coating can also be performed on the surface of the sheet metal, and in particular, coating on the metal surface is effective to cope with a metal allergy. In order to improve the feel when worn, for example, rubber touch coating can be applied, or any other material can be coated according to the application. - Regarding the dimensions of the reversing
member 4, 0.15 to 2 mm can be exemplified as the thickness, 20 to 50 mm can be exemplified as the length on the long side portion side (see W inFIGS. 1 ), and 6 to 30 mm can be exemplified as the length on the short side portion side. In addition, 8 to 30 mm can be exemplified as the length of thecomb teeth shaft portions comb teeth adjacent comb teeth - From this initial state, as indicated by a dotted arrow in
FIG. 1 , the reversingmember 4 is deformed so that thecoupling hole 22 a and thecoupling hole 22 b having had the center-to-center distance D overlap with each other, and is fastened by thecoupling member 20, whereby thefastener 2 as shown inFIG. 2 can be formed. At this time, thelong side portion 4 a and the otherlong side portion 4 b facing each other are curved so that the central region in the longitudinal direction protrudes. - For example, with a metal rivet as the
coupling member 20, the rivet is inserted and then the inserted tip portion is plastically deformed, so that the coupling can be made. That is, “swaging” enables coupling. However, the coupling method is not limited thereto, and for example, mechanical coupling can be made using other coupling members such as a bolt and a nut, or coupling can be made by welding. However, it is considered that the use of thecoupling member 20 is more excellent in operability because there is a margin for the overlapped coupling regions to relatively move. - The reversing
member 4 of thefastener 2 formed as described above has a substantially rectangular planar shape including four sides. As shown inFIG. 3A , in thelong side portion 4 a and the otherlong side portion 4 b facing each other, when the central region in the longitudinal direction is curved so as to protrude downward in the figure, thefirst comb tooth 10 and thesecond comb tooth 12 come close to the reversingmember 4, and the state is maintained by the elastic force of the reversingmember 4. That is, the state in which thefirst comb tooth 10 and thesecond comb tooth 12 are closed is maintained by the elastic force of reversingmember 4. - From this state, when the user reverses the reversing
member 4 and curves the reversingmember 4 so that the central region in the longitudinal direction thereof protrudes upward in the figure, in thelong side portion 4 a and the otherlong side portion 4 b facing each other, as shown inFIG. 3B , the state is changed to a state in which thefirst comb tooth 10 and thesecond comb tooth 12 are apart from the reversingmember 4. Then, the state is maintained by the elastic force of the reversingmember 4. That is, the state in which thefirst comb tooth 10 and thesecond comb tooth 12 are opened is maintained by the elastic force of reversingmember 4. - Accordingly, in a state where the first and
second comb teeth second comb teeth second comb teeth member 4, and then the reversingmember 4 is reversed, and the first andsecond comb teeth second comb teeth member 4 to be held. - Since the reversing
member 4 of thefastener 2 has a substantially rectangular planar shape, a state in which the first andsecond comb teeth second comb teeth second comb teeth member 4. - In addition, a
friction member 6 is provided on the entire surface of the otherlong side portion 4 b of the reversingmember 4. As thefriction member 6, an elastic material having a high friction coefficient such as rubber including silicon, elastomer, or urethane can be used. For example, in the initial state, the friction member formed in atubular shape 6 is inserted from the separation region (seeFIG. 1 ) of the reversingmember 4, attached so as to cover the otherlong side portion 4 b, and then the reversingmember 4 is deformed and coupled, whereby the otherlong side portion 4 b of the reversingmember 4 can be provided with thefriction member 6. However, the present invention is not limited thereto, and after the reversingmember 4 is deformed and coupled, thefriction member 6 can also be attached to the otherlong side portion 4 b by adhesion or the like. - In the present embodiment, since the other
long side portion 4 b is provided with thefriction member 6, the force of holding the hair between the first andsecond comb teeth friction member 6 can increase in a state where the first andsecond comb teeth fastener 2 can be more reliably fixed to the hair. - It should be noted that the reversing
member 4 is provided with a total of five attachingholes 24 including two attaching holes on the left side and three attaching holes on the right side in the figure. Furthermore, a central portion of thecoupling member 20 is also opened, and substantially three attaching holes on each of the left and right sides are provided. Thefastener 2 can be sewn onto the wig base, with a sewing thread or the like passing through the attachinghole 24 or the like. In addition, the attachinghole 24 reduces the weight of thefastener 2, and makes the reversingmember 4 easily deformed. - As described above, in the initial state, by deforming the reversing
member 4 until the positions of the coupling holes 22 a and 22 b separated by the center-to-center distance D coincide with each other, thelong side portion 4 a and the otherlong side portion 4 b are curved. At this time, the larger the center-to-center distance D between the coupling holes 22 a and 22 b is than the length W (seeFIG. 1 ) in the longitudinal direction of thelong side portion 4 a, the more greatly the reversingmember 4 is deformed, and the degree of curvature of thelong side portion 4 a and the otherlong side portion 4 b can be increased. - Accordingly, the opening angle formed by the first and
second comb teeth member 4 can be made larger in a state where the first andsecond comb teeth second comb teeth member 4, more hair can be inserted. When the opening angles of thecomb teeth second comb teeth member 4 can be increased. Accordingly, hair can be easily inserted between the opened first andsecond comb teeth member 4. - As described above, in order to increase the opening angle formed by the first and
second comb teeth member 4, it has been found that when the value of D/W is 0.15 or more between the center-to-center distance (that is, the movement amount from the initial state to the superposed state) D of the coupling holes 22 a and 22 b and the length W in the longitudinal direction of thelong side portion 4 a, the distance between the tips of the first andsecond comb teeth member 4 can be sufficiently increased. For example, when the length offirst comb tooth 10 is about 12 mm, a distance of about 6 mm can be taken between the tip of thefirst comb tooth 10 and the reversingmember 4 in the opened state. - However, when the center-to-center distance D between the coupling holes 22 a and 22 b is too large with respect to the length W of the
long side portion 4 a, the deformation of the reversingmember 4 is too large, and a large force is required when the reversingmember 4 is reversed. - When the above is comprehensively determined, between the center-to-center distance D of the coupling holes 22 a and 22 b and the length W of the
long side portion 4 a, it can be said that a following relationship is preferably satisfied: -
0.15≤D/W≤0.17. - As described above, by setting the center-to-center distance D between the coupling holes 22 a and 22 b within the above range with respect to the length W of the
long side portion 4 a, it is possible to increase the opening angle formed by the first andsecond comb teeth member 4 in the opened state, and to achieve thefastener 2 capable of easily reversing the reversingmember 4. - The
fastener 2 according to the present embodiment includes thefirst comb tooth 10 and thesecond comb tooth 12 having different lengths from one end (see arrow A inFIG. 1 ) to the other end (see arrow B inFIG. 1 ), and thefirst comb tooth 10 and thesecond comb tooth 12 are disposed adjacent to each other in the longitudinal direction of thelong side portion 4 a of the reversingmember 4. In general, human hair grows in multiple stages, is quite voluminous, has different lengths, and has different hair streams. - In order to sandwich the user's hair in the
fastener 2 to fix thefastener 2 to the hair, it is necessary to insert the hair between the first andsecond comb teeth member 4. In thefastener 2 according to the present embodiment, since thefirst comb tooth 10 and thesecond comb tooth 12 having different lengths are disposed adjacent to each other, the hair escaping and failing to be scooped up when hair is attempted to be scooped up by thefirst comb tooth 10 having a longer length can be scooped up by the adjacentsecond comb tooth 12 having a smaller length. Accordingly, more hair can be easily put into between the first andsecond comb teeth member 4. - Furthermore, in the case where the
first comb tooth 10 and thesecond comb tooth 12 having different lengths form an uneven tip shape as in the present embodiment, when the hair is sandwiched between thecomb teeth member 4, the hair is oriented not only in the extending direction of thecomb teeth comb teeth fastener 2 can be increased. Therefore, thefastener 2 can be firmly and stably fixed to the user's hair. - Therefore, in the present embodiment, it is possible to provide a
fastener 2 capable of switching between a state in which the comb teeth are closed and a state in which the comb teeth are opened by reversing the reversingmember 4, thefastener 2 capable of easily sandwiching more hair between thecomb teeth member 4, thefastener 2 capable of being firmly and stably fixed to the user's hair. - More specifically, in the
fastener 2 according to the present embodiment, in the longitudinal direction of thelong side portion 4 a of the reversingmember 4, a firstcomb teeth region 10A including twofirst comb teeth 10 arranged adjacent to each other and a secondcomb teeth region 12A including twosecond comb teeth 12 arranged adjacent to each other are arranged adjacent to each other. The firstcomb teeth region 10A and secondcomb teeth region 12A respectively including a plurality ofcomb teeth comb teeth region 10A to be reliably scooped up in the adjacent secondcomb teeth region 12A having a shorter length. - Furthermore, the present embodiment has an arrangement pattern in which the first
comb teeth region 10A and the secondcomb teeth region 12A are alternately arranged in the longitudinal direction of thelong side portion 4 a of the reversingmember 4. Referring toFIG. 2 , from the left in the figure, the firstcomb teeth region 10A, the secondcomb teeth region 12A, the firstcomb teeth region 10A, the secondcomb teeth region 12A, and the firstcomb teeth region 10A are arranged in this order. - With this arrangement pattern, the hair can be reliably sandwiched between the
comb teeth member 4 in substantially the entire region in the longitudinal direction of thelong side portion 4 a of the reversingmember 4. - Furthermore, with this arrangement pattern, the
first comb tooth 10 and thesecond comb tooth 12 are arranged bilaterally symmetrically with respect to the central portion in the longitudinal direction of thelong side portion 4 a of the reversingmember 4. This symmetrical arrangement allows the hair to be sandwiched in a well-balanced manner between thecomb teeth member 4, and thus fixation in which thefastener 2 is less likely to be displaced from the hair can be achieved. - The free ends of the first and
second comb teeth spherical head portions head portions member 4. Accordingly, it is possible to cause the first andsecond comb teeth second comb teeth head portions fastener 2 is attached to the wig base. - In the
fastener 2 according to the present embodiment, since thefastener 2 can be firmly fixed to the user's hair, in the substantially quadrilateral planar shape of the reversingmember 4, even when the lengths of the two facingshort side portions 4 c and 4d 1/d2 are shortened, a sufficient force of fixing can be obtained. Therefore, even when thehead portions second comb teeth member 4, the first andsecond comb teeth fastener 2 making it easy to scoop up the user's hair and less likely to be caught in the net of the wig. - The arrangement of the comb teeth having different lengths is not limited to the first embodiment, and any other arrangement of comb teeth can be adopted as long as the
first comb tooth 10 and thesecond comb tooth 12 having at least different lengths are provided, and thefirst comb tooth 10 and thesecond comb tooth 12 are arranged adjacent to each other in the longitudinal direction of thelong side portion 4 a of the reversingmember 4. As an example, a fastener according to second to fourth embodiments of the present invention will be described below with reference toFIGS. 4A to 4C . -
FIG. 4A is a plan view schematically showing a region of comb teeth of a fastener according to a second embodiment of the present invention. In thefastener 2 according to the present embodiment, in the longitudinal direction of thelong side portion 4 a of the reversingmember 4, a firstcomb teeth region 10A including onefirst comb tooth 10 and a secondcomb teeth region 12A including onesecond comb tooth 12 shorter than thefirst comb tooth 10 are arranged adjacent to each other. In the first embodiment, the first and secondcomb teeth regions second comb teeth comb teeth regions second comb teeth - However, similarly to the first embodiment, in the longitudinal direction of the
long side portion 4 a of reversingmember 4, an arrangement pattern in which the firstcomb teeth region 10A and the secondcomb teeth region 12A are alternately arranged is provided, and thefirst comb tooth 10 and thesecond comb tooth 12 are symmetrically arranged with respect to the central portion. - As described above, since the first and second
comb teeth regions second comb teeth long side portions 4 a of the reversingmember 4 are the same, it is possible to increase the number of states in which comb teeth having different lengths are adjacent to each other. Accordingly, a function of scooping up hair that has not been scooped up by thefirst comb tooth 10 with the adjacentsecond comb tooth 12 having a smaller length can be more effectively exhibited. -
FIG. 4B is a plan view schematically showing a region of comb teeth of a fastener according to a third embodiment of the present invention. In thefastener 2 according to the present embodiment, in the longitudinal direction of thelong side portion 4 a of the reversingmember 4, a firstcomb teeth region 10A including twofirst comb teeth 10 arranged adjacent to each other and a secondcomb teeth region 12A including onesecond comb tooth 12 shorter than thefirst comb tooth 10 are arranged adjacent to each other. In the first embodiment, the first and secondcomb teeth regions second comb teeth comb teeth regions second comb teeth - However, similarly to first embodiment, an arrangement pattern is provided in which the first
comb teeth region 10A and the secondcomb teeth region 12A are alternately arranged in the longitudinal direction of thelong side portion 4 a of the reversingmember 4. Referring toFIG. 4B , from the left in the figure, the secondcomb teeth region 12A, the firstcomb teeth region 10A, the secondcomb teeth region 12A, the firstcomb teeth region 10A, the secondcomb teeth region 12A, the firstcomb teeth region 10A, and the secondcomb teeth region 12A are arranged in this order. In addition, similarly to first embodiment, thefirst comb tooth 10 and thesecond comb tooth 12 are arranged bilaterally symmetrically with respect to the central portion in the longitudinal direction of thelong side portion 4 a of the reversingmember 4. - In the present embodiment, since the number of
first comb teeth 10 having a larger length is large, more hair can be scooped up using thefirst comb teeth 10. -
FIG. 4C is a plan view schematically showing a region of comb teeth of a fastener according to a fourth embodiment of the present invention. In thefastener 2 according to the present embodiment, in the longitudinal direction of thelong side portion 4 a of the reversingmember 4, it is different from the first embodiment in that a third comb teeth region 14A including one third comb tooth 14 shorter than thesecond comb tooth 12 is provided, in addition to a firstcomb teeth region 10A including twofirst comb teeth 10 arranged adjacent to each other and a secondcomb teeth region 12A including onesecond comb tooth 12 shorter than thefirst comb tooth 10. - However, similarly to first embodiment, the
first comb tooth 10, thesecond comb tooth 12, and the third comb tooth 14 are arranged bilaterally symmetrically with respect to the central portion. - In the present embodiment, since the third comb tooth 14 shorter than the
second comb tooth 12 is disposed adjacent to thesecond comb tooth 12, hair that has not been scooped up by thefirst comb tooth 10 can be scooped up by the adjacentsecond comb tooth 12 having a smaller length, and furthermore, hair that has not been scooped up by thesecond comb tooth 12 can be scooped up by the adjacent third comb tooth 14 having a still smaller length. Therefore, more hair can be effectively sandwiched between thecomb teeth member 4. - As described above, in consideration of making a large number of states in which comb teeth with different lengths are adjacent to each other without unnecessarily increasing the length of the
long side portion 4 a of the reversingmember 4, the number ofcomb teeth comb teeth regions comb teeth regions comb teeth comb teeth regions - Next, with the
fastener 2 according to the first embodiment being actually manufactured as an example, and with theconventional fastener 102 as a comparative example, a result of performing a comparative test will be described.FIG. 5A is a view (photograph) showing a fastener of an example of the present invention.FIG. 5B is a view (photograph) showing a fastener of a comparative example being a conventional fastener. The example shown inFIG. 5A has the same structure as thefastener 2 according to the first embodiment and includes afirst comb tooth 10 and asecond comb tooth 12 having different lengths. On the other hand, in the comparative example being a conventional fastener, all the comb teeth have the same length. It should be noted that except for the length of the comb teeth, the example and the comparative example have substantially the same shape. - First, with reference to
FIG. 6 , a description will be given of the example 1 in which the number of hairs scooped up with the comb teeth of the fastener is compared.FIG. 6 is a view (photograph) showing a test of measuring the number of hairs that can be scooped up with comb teeth using the fastener of the example. - As shown in
FIG. 6 , a test in which 100 sewing threads likened to hair were fixed to a plate, and the sewing threads were sandwiched between comb teeth and a reversing member with each of thefastener 2 of the example shown inFIG. 5A and thefastener 102 of the comparative example shown inFIG. 5B was performed 10 times. The results are shown in the following table. -
TABLE 1 First Second Third Fourth Fifth Sixth Seventh Eighth Ninth Tenth time time time time time time time time time time Average Example 33 32 30 26 35 24 23 29 32 31 29.5 Comparative 14 17 30 20 27 22 18 34 30 26 23.8 example - As described above, it was found that the average of 29.5 sewing threads can be sandwiched in the example, and more sewing threads can be sandwiched than the average of 23.8 sewing threads in the comparative example.
- Accordingly, it was demonstrated that more hair can be sandwiched by arranging the
first comb tooth 10 and thesecond comb tooth 12 having different lengths adjacent to each other. - Next, with reference to
FIGS. 7A and 7B , a description will be given of the example 2 in which a state in which hair sandwiched between fasteners according to the example and the comparative example is entangled with comb teeth is compared and observed using sewing threads likened to hairs.FIG. 7A is a view (photograph) showing a state of hair when hair is sandwiched between the comb teeth and the reversing member using thefastener 2 of the example.FIG. 7B is a view (photograph) showing a state of hair when hair is sandwiched between the comb teeth and the reversing member using thefastener 102 of the comparative example. - As indicated by an arrow in
FIG. 7A , in thefastener 2 of the example, since thefirst comb tooth 10 and thesecond comb tooth 12 having different lengths form an uneven tip shape, it was found that hair orients not only along a direction in which thecomb teeth comb teeth fastener 102 of the comparative example in which all the comb teeth have the same length, it was found that almost all the hairs orient in the extending direction of the comb teeth. - Accordingly, it was possible to demonstrate the factor that the force of sandwiching and fixing the hair using the
fastener 2 of the example is larger than the force of sandwiching and fixing the hair using thefastener 102 of the comparative example. - Next, with reference to
FIG. 8 , a description will be given of the example 3 in which a force of sandwiching and fixing hair with thefastener 2 of the example and a force of sandwiching and fixing hair with thefastener 102 of the comparative example are measured.FIG. 8 is a view (photograph) showing measuring, using a spring balance, a force capable of sandwiching the hair between the comb teeth and the reversing member of the fastener and fixing the fastener to the hair. - As shown in
FIG. 8 , the sewing thread likened to hair was sandwiched between the comb teeth and the reversing member of thefasteners fasteners - Specifically, the force of pulling the spring balance was increased, and the value of the spring balance when the
fasteners fastener 102 of the comparative example, whereas the force of fixing was 40 to 50 g in thefastener 2 of the example. - Accordingly, it was found that the force of fixing of the
fastener 2 of the example is larger than the force of fixing of thefastener 102 of the comparative example. Therefore, it was demonstrated that in thefastener 2 of the example in which due to thefirst comb tooth 10 and thesecond comb tooth 12 having different lengths, the sandwiched hair orients not only in the extending direction of the comb teeth but also in a direction oblique to the extending direction of the comb teeth, thefastener 2 can be fixed to the hair with a larger force. - As described above, in the
fastener 2 including thefirst comb tooth 10 and thesecond comb tooth 12 having different lengths, since the force of sandwiching and fixing the hair is large, even when the lengths of the two facingshort side portions 4 c and 4d 1/d2 are shortened in the substantially quadrilateral planar shape of the reversingmember 4, a sufficient force of fixing can be secured. For example, in the substantially quadrilateral planar shape of the reversingmember 4, when the length of the long side portion is L1 and the length of the short side portion is L2, it was found that a sufficient force of fixing can be obtained even when the value of L2/L1 is 0.3 or less. However, since too large difference between the long side and the short side will also have a tendency of difficulty in use, the following range is considered to be preferred: -
0.2≤L2/L10.3. - Accordingly, even when the tips of the
first comb tooth 10 and thesecond comb tooth 12 extend outside the substantially quadrilateral planar shape, it is possible to suppress the catch in the net of the wig when thefastener 2 is attached to the wig base. Therefore, it is possible to provide afastener 2 making it easy to scoop up the user's hair and less likely to be caught in the net of the wig. - (Description of Wig to which Fastener is Attached)

It should be noted that the number offasteners 2 attached to thewig base 30 is not limited to two, and any number offasteners 2 can be attached according to the application. - As a method for attaching the
fastener 2 to thewig base 30, it is conceivable to sew thefastener 2 to thewig base 30, with a sewing thread passing through a plurality of attachingholes 24 or an opening of thecoupling member 20 provided in thefastener 2. However, the present invention is not limited thereto, and thefastener 2 can be attached to thewig base 30 by any known method including using another coupling member. - The
false hairs 32 are planted in thiswig base 30 to form thewig 40. When the user wears thewig 40, after thewig base 30 is worn on the head portion, the user's hair is inserted between the comb teeth and the reversing member with the comb teeth of thefastener 2 in the region in front of the ear (temple) opened, and then the reversing member is reversed, and the hair is sandwiched between the comb teeth and the reversing member to be held. - Accordingly, the
wig 40 can stably be fixed to the head portion. - As described above, the

fastener 2 according to each of the above embodiments, in the longitudinal direction of thelong side portion 4 a, a firstcomb teeth region 10A including the onefirst comb tooth 10 or a plurality of thefirst comb tooth 10 arranged adjacent to each other and a secondcomb teeth region 12A including the onesecond comb tooth 12 or a plurality of thesecond comb tooth 12 arranged adjacent to each other are arranged adjacent to each other. - Accordingly, the hair having not been scooped up in the first
comb teeth region 10A can be reliably scooped up in the adjacent secondcomb teeth region 12A having a smaller length. - In particular, in the first to third embodiments described above, in the longitudinal direction of
long side portion 4 a, since an arrangement pattern in which the firstcomb teeth region 10A and the secondcomb teeth region 12A are alternately arranged in the longitudinal direction of thelong side portion 4 a is provided, the hair can be reliably sandwiched between thecomb teeth member 4 over substantially the entire region in the longitudinal direction of thelong side portion 4 a. - Furthermore, in the
fastener 2 according to each of the above embodiments, since thefirst comb tooth 10 and thesecond comb tooth 12 are disposed symmetrically with respect to the central portion in the longitudinal direction of thelong side portion 4 a, the hair can be sandwiched between thecomb teeth member 4 in a well-balanced manner, and thus fixing in which thefastener 2 is less likely to be displaced from the hair can be achieved. - The fastener according to the present invention can be applied not only to the application of fixing the wig base described above, but also to any other fields as long as an object to be fixed is inserted between the comb teeth and the reversing member, the reversing member is reversed, and the object is sandwiched and fixed by the elastic force of the reversing member.
