Description

Fastening piece

Technical Field

The present invention relates to a fastener for fixing an object to be clamped, and more particularly, to a fastener suitable for fixing a wig base having a wig implanted therein to a head of a user.

Background

A wig base having a wig implanted therein is sometimes fixed to a user's head by a wig fastener. The wig fastener is attached to the back side (side in contact with the head of the user) of the wig base by sewing or the like, and the wig base can be fixed to the head of the user by sandwiching the hair of the user with the wig fastener. Among such fasteners for wigs, fasteners using a reversible member having a plurality of comb teeth attached thereto have been proposed (for example, see patent document 1). In the wig fastener described in patent document 1, the user's hair can be held and fixed between the comb teeth and the reversible member by opening the comb teeth for the comb teeth to pick up the user's hair and then reversing the reversible member to close the comb teeth.

Problems to be solved by the invention

In the fastener for a wig described in patent document 1, a plurality of comb teeth attached to the reversible member are formed to have the same length. Generally, human hair grows in multiple stages, and is quite bulky, and the length of the hair varies, and the hair flow varies. Therefore, when the lengths of the comb teeth are the same, the tips of the comb teeth are aligned in a straight line, and therefore, when the tips of the comb teeth contact the hair, the hair flow is deviated, and the hair escapes, making it difficult to pick up a sufficient amount of hair.

Further, when the tips of the comb teeth are aligned in a straight line, the hair to be held tends to be oriented in the extending direction of the comb teeth, and there is a possibility that the fastener cannot be fixed with a sufficient force.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a fastener which can clamp a larger amount of user's hair and can strongly fix the hair to the user by inverting a flip member to switch between a state in which comb teeth are closed and a state in which the comb teeth are opened.

Means for solving the problems

In order to solve the above problem, a fastener according to the present invention includes:

a turnover member having a long side portion bent in a manner that a central region in a longitudinal direction is convex, and made of an elastic material; and

a plurality of comb teeth connected to the long side portion at one end and having a free end at the other end, extending in a direction intersecting the longitudinal direction of the long side portion, and arranged at predetermined intervals along the longitudinal direction of the long side portion,

the plurality of comb teeth include at least a first comb tooth and a second comb tooth having different lengths from the one end to the other end, the first comb tooth and the second comb tooth being arranged adjacent to each other in a longitudinal direction of the long side portion,

the plurality of comb teeth are changed to a state close to the reversing member and a state separated from the reversing member by reversing the reversing member.

Effects of the invention

As described above, in the present invention, it is possible to provide a fastener which can grip more user's hair and can strongly fix to the user's hair, and which can switch between a state in which comb teeth are closed and a state in which comb teeth are open by inverting an inversion member.

Fig. 1 is a plan view schematically showing an inverted member constituting a fastener according to a first embodiment of the present invention.

< flip member >

Fig. 1 shows a planar shape of the inversion member 4 in an initial state before deformation. The reversing member 4 of the present embodiment is formed of a metal thin plate as an elastic material. However, the present invention is not limited to this, and any other material such as a resin material may be used as long as it is elastic. The reversible member 4 has a substantially quadrangular planar shape in an initial state, and the substantially quadrangular planar shape is constituted by a long side portion 4a, another long side portion 4b opposed to the long side portion 4a, and two opposed short side portions 4c, 4d1/4d 2.

In the short side portions 4d1 and 4d2 on the left side of the drawing, the short side portion 4d1 and the short side portion 4d2 may be separated from each other, and the flip member 4 in the initial state may have a substantially C-shaped planar shape. The short side portion 4d1 and the short side portion 4d2 have a connection hole 22a and a connection hole 22b in the vicinity of their ends with a space therebetween. The distance between the centers of the

coupling holes

22a and 22b is denoted by D.

The long side portion 4a is provided with a plurality of

comb teeth

10 and 12, and one end (see arrow a in fig. 1) of each of the

comb teeth

10 and 12 is connected to the long side portion 4a, and the other end (see arrow B in fig. 1) is a free end. If the

comb teeth

10, 12 are explained in more detail, they have a first comb tooth 10 and a second comb tooth 12 which differ in length from one end to the other. The first comb tooth 10 is formed longer than the second comb tooth 12.

The first comb teeth 10 include a shaft 10a and a substantially spherical head 10b provided at a free end of the shaft 10 a. Similarly, the second comb teeth 12 include a shaft portion 12a and a substantially spherical head portion 12b provided at a free end of the shaft portion 12a. The first comb teeth 10 and the second comb teeth 12 are formed of a metal material, and are attached to the long side portion 4a of the flip member 4 by, for example, welding or brazing.

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 4a of the inversion member 4. However, the long side portion 4a does not always need to be orthogonal to the longitudinal direction thereof, and may extend in a direction inclined with respect to the longitudinal direction of the long side portion 4a. However, the first comb tooth 10 and the second comb tooth 12 are preferably arranged substantially parallel to each other.

As described above, the first comb teeth 10 and the second comb teeth 12 extend in a direction intersecting the longitudinal direction of the long side portion 4a of the reversible member 4. The first comb teeth 10 and the second comb teeth 12 are arranged at predetermined intervals in the longitudinal direction of the long side portion 4a of the flip member 4.

The flip member 4, the first comb teeth 10, and the second comb teeth 12 may be formed of a metal material such as stainless steel, carbon steel, aluminum, copper, titanium, or the like. Further, the surface of the metal thin plate may be coated, and in particular, the coating of the metal surface is effective for coping with metal allergy. In order to improve the touch at the time of attachment, for example, coating of rubber touch may be performed, or any other material may be coated for the purpose.

When describing the size of the reversible member 4, the thickness is exemplified by 0.15 to 2mm, the length on the long side (see W in fig. 1) is exemplified by 20 to 50mm, and the length on the short side is exemplified by 6 to 30mm. The length of the

comb teeth

10, 12 is exemplified by 8 to 30mm, and the outer diameter of the

shaft portions

10a, 12a of the

comb teeth

10, 12 is exemplified by 0.3 to 2mm. The interval between

adjacent comb teeth

10 and 12 is, for example, 1 to 3mm. However, these dimensions are illustrative of the case of applying to wigs, and any other dimensions may be used depending on the application.

From this initial state, as shown by the broken line arrow in fig. 1, the fastener 2 shown in fig. 2 can be formed by deforming the reversible member 4 so that the

coupling holes

22a and 22b at the center-to-center distance D overlap each other and fastening them by the coupling member 20. At this time, the opposing long side portion 4a and the other long side portion 4b are curved so that the central region in the longitudinal direction thereof is convex.

For example, a metal rivet may be used as the coupling member 20, and after the rivet is inserted, the inserted tip end portion is plastically deformed and coupled. That is, the connection may be by "riveting". However, the connection method is not limited to this, and for example, mechanical connection may be performed using another connection structure such as a bolt or a nut, or connection may be performed by welding. However, since the connecting member 20 has more room for relative movement in the overlapping connecting region, the operability is considered to be more excellent.

< fastener >

The reversing member 4 of the fastener 2 formed as described above has a substantially rectangular planar shape constituted by four sides. As shown in fig. 3A, when the opposing long side portion 4a and the other long side portion 4b are curved such that the central regions in the longitudinal direction thereof are convex toward the lower side in the drawing, the first comb tooth 10 and the second comb tooth 12 are in a state of being close to the reversible member 4, and this state is maintained by the elastic force of the reversible 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 the flip member 4.

When the user turns the reversible member 4 from this state, as shown in fig. 3B, the opposing long side portion 4a and the other long side portion 4B are curved so that the central regions in the longitudinal direction thereof are convex toward the upper side in the drawing, and the first comb tooth 10 and the second comb tooth 12 are separated from the reversible member 4. Then, this state is maintained by the elastic force of the flip member 4. That is, the state in which the first comb tooth 10 and the second comb tooth 12 are opened is maintained by the elastic force of the flip member 4.

Accordingly, when the first comb tooth 10 and the second comb tooth 12 are opened, the user's hair is picked up by the first comb tooth 10 and the second comb tooth 12, a predetermined amount of hair is put between the first comb tooth 10, the second comb tooth 12, and the reversible member 4, and then the reversible member 4 is reversed, and the first comb tooth 10 and the second comb tooth 12 are changed from the opened state to the closed state, whereby a predetermined amount of hair can be held between the first comb tooth 10, the second comb tooth 12, and the reversible member 4.

Since flip member 4 of fastener 2 has a substantially rectangular planar shape, it is possible to stably maintain first comb tooth 10 and second comb tooth 12 in the open state and in the closed state, and to easily flip member 4 to change the opening and closing of first comb tooth 10 and second comb tooth 12.

A friction member 6 is provided on the entire surface of the other long side portion 4b of the reversible member 4. As the friction member 6, an elastic material having a high friction coefficient such as rubber including silicone, elastomer, urethane, or the like can be used. For example, the friction member 6 formed in a tubular shape may be inserted from a separate region (refer to fig. 1) of the reversed member 4 in an initial state, attached so as to cover the other long-side portion 4b, and then the friction member 6 may be provided to the other long-side portion 4b of the reversed member 4 by deforming and coupling the reversed member 4. However, the present invention is not limited to this, and the friction member 6 may be attached to the other long side portion 4b by bonding or the like after the inversion member 4 is deformed and connected.

In the present embodiment, since the friction member 6 is provided on the other long side portion 4b, in a state where the first comb tooth 10 and the second comb tooth 12 are closed, the force for holding the hair between the first comb tooth 10 and the second comb tooth 12 and the friction member 6 can be increased, and the fastener 2 can be more reliably fixed to the hair.

A total of five mounting holes 24 are provided in the flip member 4, two holes are provided on the left side of the drawing, and three holes are provided on the right side. The center of the coupling member 20 is also open, and three mounting holes are provided on each of the left and right sides. The fastener 2 can be sewn to the wig base by inserting a thread or the like through the mounting holes 24 or the like. Further, the weight of the fastener 2 is reduced by the mounting hole 24, and the reversible member 4 is easily deformed.

< opening of comb teeth >

In the initial state as described above, the long-side portion 4a and the other long-side portion 4b are bent by deforming the reversible member 4 until the positions of the

coupling holes

22a and 22b separated by the center-to-center distance D match. At this time, the larger the center-to-center distance D between the

coupling holes

22a and 22b is with respect to the length W in the longitudinal direction of the long side portion 4a (see fig. 1), the greater the degree to which the inversion member 4 can be deformed more largely to bend the long side portion 4a and the other long side portion 4b.

Accordingly, in a state where the first comb tooth 10 and the second comb tooth 12 are open, the opening angle formed by the first comb tooth 10 and the second comb tooth 12 and the flip member 4 can be made larger. Therefore, the hairs can be inserted to the vicinity of the root portions of the first comb tooth 10 and the second comb tooth 12 fixed to the reversible member 4, and thus more hairs can be inserted. When the opening angle of the

comb teeth

10 and 12 in the opened state is large, the distance between the tip ends of the first and

second comb teeth

10 and 12 and the flip member 4 can be made large. This allows hair to be easily inserted between the opened first and

second comb teeth

10 and 12 and the reversible member 4.

Thus, it is known that: in order to increase the opening angle between the first and

second comb teeth

10 and 12 and the inversion member 4, if the value of D/W between the distance D between the centers of the

coupling holes

22a and 22b (that is, the amount of movement from the initial state to the overlapping state) and the length W of the long side portion 4a in the longitudinal direction is 0.15 or more, the distance between the tips of the first and

second comb teeth

10 and 12 and the inversion member 4 can be sufficiently increased. For example, when the length of the first comb tooth 10 is about 12mm, the distance between the tip of the first comb tooth 10 and the flip member 4 can be about 6mm in the opened state.

However, if the distance D between the centers of the

coupling holes

22a and 22b is too large with respect to the length W of the long side portion 4a, the deformation of the inversion member 4 becomes too large, and a large force is required at the time of inversion.

When the above is comprehensively determined, it can be said that the following relationship is preferably established between the center-to-center distance D of the

coupling holes

22a, 22b and the length W of the long side portion 4a.

0.15≤D/W)≤0.17

By setting the center-to-center distance D of the

coupling holes

22a, 22b with respect to the length W of the long side portion 4a within the above range, the opening angle formed by the first comb tooth 10, the second comb tooth 12 and the reversible member 4 in the opened state can be increased, and the fastener 2 capable of easily reversing the reversible member 4 can be realized.

(Length of comb teeth)

The fastener 2 of the present embodiment includes a first comb tooth 10 and a 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 arranged adjacent to each other in the longitudinal direction of the long side portion 4a of the reversible member 4. Generally, human hair grows in multiple stages, and is quite bulky, and the hair length and hair flow vary.

In order to clamp the user's hair to the fastener 2 and fix the fastener 2 to the hair, the hair needs to be inserted between the first and

second comb teeth

10 and 12 in the opened state and the reversible member 4. In the fastener 2 of the present embodiment, since the first comb teeth 10 and the second comb teeth 12 having different lengths are arranged adjacent to each other, it is possible to lift the hair that escapes and cannot be lifted when lifting the hair with the first comb teeth 10 having a long length, with the second comb teeth 12 having a short length adjacent to each other. This makes it easy to insert more hairs between the first and

second comb teeth

10 and 12 and the flip member 4.

Further, as described in the present embodiment, when the first comb teeth 10 and the second comb teeth 12 having different lengths form the concave-convex tip shape, when the hair is sandwiched between the

comb teeth

10 and 12 and the flip member 4, the hair is oriented not only in the extending direction of the

comb teeth

10 and 12 but also in a direction inclined with respect to the extending direction of the comb teeth. Since the held hair is entangled with the

comb teeth

10 and 12 at various angles, the force with which the hair can be held and fixed by the fastener 2 is large. Therefore, the fastener 2 can be strongly and stably fixed to the hair of the user.

Therefore, in the present embodiment, the fastener 2 can be provided which switches between the state in which the comb teeth are closed and the state in which the comb teeth are opened by inverting the inversion member 4, and the fastener 2 can easily hold more hair between the

comb teeth

10 and 12 and the inversion member 4 and can strongly and stably fix the hair to the user.

More specifically, the fastener 2 of the present embodiment is disposed adjacent to the long side portion 4a of the inversion member 4 in the longitudinal direction thereof: a first comb tooth region 10A composed of two first comb teeth 10 arranged adjacently, and a second comb tooth region 12A composed of two second comb teeth 12 arranged adjacently. By the first comb-tooth region 10A and the second comb-tooth region 12A in which the plurality of

comb teeth

10 and 12 are arranged adjacent to each other, it is possible to more reliably pick up hair, and hair that cannot be picked up by the first comb-tooth region 10A can be reliably picked up by the adjacent second comb-tooth region 12A having a short length.

In the present embodiment, the first comb-tooth regions 10A and the second comb-tooth regions 12A are alternately arranged in the longitudinal direction of the long side portion 4a of the inversion member 4. Referring to fig. 2, the first comb-tooth region 10A, the second comb-tooth region 12A, and the first comb-tooth region 10A are arranged in this order from the left side of the drawing.

With such an arrangement pattern, the hair can be reliably held between the

comb teeth

10, 12 and the reversible member 4 over substantially the entire longitudinal region of the long side portion 4a of the reversible member 4.

Further, according to such an arrangement pattern, the first comb tooth 10 and the second comb tooth 12 are arranged in bilateral symmetry with respect to the center portion in the longitudinal direction of the long side portion 4a of the inversion member 4. With such a symmetrical arrangement, the hair can be held between the

comb teeth

10 and 12 and the reversible member 4 in a well-balanced manner, and the fastener 2 can be fixed so as not to be easily displaced from the hair.

< position of head of comb teeth >

Substantially

spherical heads

10b, 12b are provided at the free ends of the first and

second comb teeth

10, 12, but the

heads

10b, 12b are located outside the substantially quadrangular planar shape of the flip member 4. This makes it easy to lift the user's hair up to the first comb teeth 10 and the second comb teeth 12. On the other hand, when the first and

second comb teeth

10 and 12 are excessively elongated, the possibility of the

heads

10b and 12b scraping the net of the wig when the fastener 2 is attached to the wig base becomes high.

In the fastening tool 2 of the present embodiment, since the fastening tool 2 can be strongly fixed to the hair of the user, a sufficient fixing force can be obtained even if the lengths of the two opposing short side portions 4c, 4d1/4d2 are shortened in the substantially rectangular planar shape of the reversible member 4. Therefore, even if the

heads

10b, 12b of the first and

second comb teeth

10, 12 are located outside the substantially quadrangular planar shape of the flip member 4, the first and

second comb teeth

10, 12 do not excessively extend. This makes it possible to provide the fastener 2 that is easy to pick up the user's hair and less likely to scrape the net of the wig.

(fasteners of other embodiments of the invention)

The arrangement of the comb teeth having different lengths is not limited to the first embodiment described above, and any other arrangement of the comb teeth may be employed as long as at least the first comb tooth 10 and the second comb tooth 12 having 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 4a of the reversible member 4. As one example thereof, referring to fig. 4A to 4C, a description will be given below of fasteners according to second to fourth embodiments of the present invention.

< fastener of second embodiment >

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 the fastener 2 of the present embodiment, the long side portion 4a of the reversible member 4 is disposed adjacent to each other in the longitudinal direction: a first comb-tooth region 10A constituted by one first comb-tooth 10 and a second comb-tooth region 12A constituted by one second comb-tooth 12 shorter than the first comb-tooth 10. In the first embodiment described above, the first comb-tooth region 10A and the second comb-tooth region 12A are configured such that a plurality of first comb-teeth 10 and a plurality of second comb-teeth 12 are arranged adjacent to each other, but the present embodiment is different in that the first comb-tooth region 10A and the second comb-tooth region 12A are configured by one first comb-tooth 10 and one second comb-tooth 12, respectively.

However, as in the first embodiment, the first comb tooth regions 10A and the second comb tooth regions 12A are alternately arranged in the longitudinal direction of the long side portion 4a of the inversion member 4, and the first comb tooth 10 and the second comb tooth 12 are arranged symmetrically with respect to the center portion.

Since the first comb-tooth region 10A and the second comb-tooth region 12A are each constituted by one first comb-tooth 10 and one second comb-tooth 12, more comb-teeth having different lengths can be adjacent to each other even if the length of the long side portion 4a of the reversible member 4 is the same. This makes it possible to more effectively play a role of picking up hairs that cannot be picked up by the first comb teeth 10 with the second comb teeth 12 having short lengths adjacent to each other.

< fastener of third embodiment >

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 the fastener 2 of the present embodiment, the long side portion 4a of the reversible member 4 is disposed adjacent to each other in the longitudinal direction: a first comb tooth region 10A including two first comb teeth 10 arranged adjacent to each other, and a second comb tooth region 12A including one second comb tooth 12 shorter than the first comb tooth 10. In the first embodiment described above, the first comb-tooth region 10A and the second comb-tooth region 12A are configured such that the same number of first comb-teeth 10 and the same number of second comb-teeth 12 are arranged adjacent to each other, but the present embodiment is different in that the first comb-tooth region 10A and the second comb-tooth region 12A are configured by the different numbers of first comb-teeth 10 and second comb-teeth 12.

However, as in the first embodiment, the first comb-tooth regions 10A and the second comb-tooth regions 12A are alternately arranged in the longitudinal direction of the long side portion 4a of the inversion member 4. Referring to fig. 4B, the second comb-tooth region 12A, the first comb-tooth region 10A, and the second comb-tooth region 12A are arranged in this order from the left side of the drawing. Further, as in the first embodiment, the first comb tooth 10 and the second comb tooth 12 are arranged symmetrically with respect to the center portion in the longitudinal direction of the long side portion 4a of the reversible member 4.

In the present embodiment, since the number of the first comb teeth 10 having a long length is large, more hairs can be picked up by using the first comb teeth 10.

< fastener of fourth embodiment >

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. The fastener 2 of the present embodiment differs from the first embodiment in that a third comb tooth region 14A including a third comb tooth 14 shorter than the second comb tooth 12 is provided in addition to a first comb tooth region 10A including two first comb teeth 10 arranged adjacent to each other and a second comb tooth region 12A including a second comb tooth 12 shorter than the first comb tooth 10 in the longitudinal direction of the long side portion 4A of the reversible member 4.

However, as in the first embodiment, the first comb tooth 10, the second comb tooth 12, and the third comb tooth 14 are arranged symmetrically with respect to the center portion.

In the present embodiment, since the third comb teeth 14 shorter than the second comb teeth 12 are arranged adjacent to each other, the hairs that cannot be picked up by the first comb teeth 10 can be picked up by the second comb teeth 12 that are adjacent to each other and the hairs that cannot be picked up by the second comb teeth 12 can be picked up by the third comb teeth 14 that are adjacent to each other and have a shorter length. Therefore, more hairs can be effectively held between the

comb teeth

10, 12, 14 and the flip member 4.

As described above, in consideration of creating a state in which a plurality of comb teeth having different lengths are adjacent to each other without excessively increasing the length of the long side portion 4A of the inversion member 4, the number of

comb teeth

10, 12, 14 in each

comb tooth region

10A, 12A, 14A is preferably about one to three. In consideration of the balance of the amount of hair picked up by the respective comb-

tooth regions

10A, 12A, and 14A, the number of

comb teeth

10, 12, and 14 in the respective comb-

tooth regions

10A, 12A, and 14A is preferably the same, or even if there is a difference in the number, the difference is about one or two.

(examples)

Next, the results of a comparative test performed using the fastener 2 of the first embodiment as an example and the conventional fastener 102 as a comparative example will be described. Fig. 5A is a view (photograph) showing a fastener according to an embodiment of the present invention. Fig. 5B is a view (photograph) showing a fastener as a comparative example of the conventional fastener. The example shown in fig. 5A has the same configuration as the fastener 2 of the first embodiment described above, and includes a first comb tooth 10 and a second comb tooth 12 having different lengths. On the other hand, in the comparative example as the conventional fastener, all the comb teeth have the same length. The examples and comparative examples have almost the same shape except for the length of the comb teeth.

< example 1 >

First, referring to fig. 6, example 1 in which the number of hairs picked up by the comb teeth of the fastener is compared will be described. Fig. 6 is a diagram (photograph) showing a test for measuring the number of hairs that can be picked up using the fastener comb teeth of the example.

As shown in fig. 6, one hundred sewing threads, which were regarded as hairs, were fixed to the plate, and tests were performed 10 times to hold the sewing threads between the comb teeth and the flip member using the fastener 2 of the example shown in fig. 5A and the fastener 102 of the comparative example shown in fig. 5B, respectively. The results are shown in the following table.

(Table 1)

	1 time of	2 times (one time)	3 times of	4 times (twice)	5 times (twice)	6 times of	7 times of	8 times of	9 times of	10 times of	Average
												Examples	33	32	30	26	35	24	23	29	32	31	29.5
Comparative example	14	17	30	20	27	22	18	34	30	26	23.8

As described above, it is clear that the fastener 2 of the embodiment can hold an average of 29.5 sewing threads and can hold more sewing threads than the comparative example which holds an average of 23.8 sewing threads. It was confirmed that more hairs can be held by adjacently arranging the first comb tooth 10 and the second comb tooth 12 having different lengths.

< example 2 >

Next, referring to fig. 7A and 7B, example 2 will be described, and this example 2 is a comparative observation of a state in which hairs held by fasteners of examples and comparative examples are tangled in comb teeth, using a sewing thread regarded as hairs. Fig. 7A is a view (photograph) showing a state of hair when the hair is sandwiched between comb teeth and a reversible member using the fastener 2 of the embodiment. Fig. 7B is a diagram (photograph) showing a state of hair when hair is sandwiched between comb teeth and a flip member using the fastener 102 of the comparative example.

It is clear that: as shown by the arrows in fig. 7A, in the fastener 2 of the embodiment, since the first comb tooth 10 and the second comb tooth 12 having different lengths form the concave-convex tip shape, the hair is oriented not only in the extending direction of the

comb teeth

10, 12 but also in a direction inclined with respect to the extending direction of the

comb teeth

10, 12. On the other hand, it is clear that: in the fastener 102 of the comparative example in which the lengths of all the comb teeth are the same, almost all the hairs are oriented in the extending direction of the comb teeth.

Thus, the main reason why the force for holding the hair by the fastener 2 of the example is larger than the force for holding the hair by the fastener 102 of the comparative example can be confirmed.

< example 3 >

Next, example 3 is described with reference to fig. 8, and in example 3, the force with which the hair is clamped and fixed by the fastener 2 of the example and the force with which the hair is clamped and fixed by the fastener 102 of the comparative example are measured. Fig. 8 is a diagram (photograph) showing a state in which a force capable of clamping hair between comb teeth of a fastener and a flip member and fixing the fastener to the hair is measured using a spring scale.

As shown in fig. 8, the

fastening pieces

2 and 102 of the examples and comparative examples were pulled by a spring balance while holding a sewing thread, which was regarded as hair, between the comb teeth and the flip member of the

fastening pieces

2 and 102, and the fixing force was measured.

Specifically, the force for pulling the spring balance is gradually increased, and the value of the spring balance when the

fastener

2 or 102 starts moving is set as the fixed force. As a result, the fastening force in the fastening device 102 of the comparative example was 20 to 30g, whereas the fastening force in the fastening device 2 of the example was 40 to 50g.

Thus, it is clear that the force of fixation of the fastener 2 of the embodiment is larger than that of the fastener 102 of the comparative example. Thus, it was confirmed that the hair held by the first comb tooth 10 and the second comb tooth 12 having different lengths can be fixed to the hair with a greater force in the fastener 2 of the embodiment in which the hair is oriented not only in the extending direction of the comb teeth but also in a direction inclined with respect to the extending direction of the comb teeth.

In this manner, in the fastener 2 including the first comb tooth 10 and the second comb tooth 12 having different lengths, since the force for sandwiching and fixing the hair is large, a sufficient fixing force can be secured even if the lengths of the two opposing short side portions 4c, 4d1/4d2 are shortened in the substantially quadrangular planar shape of the reversible member 4. For example, it is recognized that: in the substantially rectangular planar shape of the reversible member 4, when the length of the long side portion is L1 and the length of the short side portion is L2, a sufficient fixing force can be obtained even if the value of L2/L1 is 0.3 or less. However, since too large a difference between the long side and the short side tends to make it difficult to use, it is considered that the following range is preferable.

0.2≤L2/L1≤0.3

Thus, even if the distal ends of the first and

second comb teeth

10 and 12 extend to the outside of the substantially quadrangular planar shape, it is possible to suppress scraping of the net of the wig when the fastener 2 is attached to the wig base. Therefore, the fastening tool 2 can be provided which is easy to pick up the user's hair and less likely to scrape the net of the wig.

(instruction of wig fitted with fastener)

Next, a wig to which the fastener of the above-described various embodiments is attached will be described with reference to fig. 9. FIG. 9 is a top view schematically showing a wig equipped with the fastener of the present invention.

Fig. 9 shows a state where two fasteners 2 are attached to the back surface side (the side contacting the head of the user) of the wig base 30. In particular, in the vicinity of the peripheral edge portion of the wig base 30, i.e., the region in front of the user's ear (temple). It should be noted that the number of the fastening members 2 to be assembled to the wig base 30 is not limited to two, and any number may be assembled according to the purpose.

As a method of attaching the fastener 2 to the wig base 30, it is conceivable to sew the fastener 2 to the wig base 30 through a suture from the plurality of attachment holes 24 provided in the fastener 2 and the opening of the connecting member 20. However, it is not limited thereto, and the fastener 2 may be mounted to the wig base 30 by any known method such as using other coupling members.

The wig 40 is formed by implanting the artificial hair 32 on the wig base 30. When attaching the wig 40, the user puts the comb teeth of the fastener 2 located in the area in front of the ear (temple) in an open state after attaching the wig base 30 to the head, and after inserting the user's hair between the comb teeth and the flip member, the flip member is flipped, and the hair is held while being sandwiched between the comb teeth and the flip member. This enables the wig 40 to be stably fixed to the head.

(fastener according to the embodiment of the invention)

As described above, the fastener 2 according to each of the above embodiments includes: a flip member 4 made of an elastic material and having a long side portion 4a bent so that a central region in a longitudinal direction thereof is convex; and a plurality of

comb teeth

10, 12 connected to the long side portion 4a at one end and having a free end at the other end, extending in a direction intersecting the longitudinal direction of the long side portion 4a, and arranged at a predetermined interval in the longitudinal direction of the long side portion 4a, the plurality of

comb teeth

10, 12 including at least a first comb tooth 10 and a second comb tooth 12 having different lengths from one end to the other end, the first comb tooth 10 and the second comb tooth 12 being arranged adjacent to each other in the longitudinal direction of the long side portion 4a, and the plurality of

comb teeth

10, 12 being changed to a state of being close to the reversible member 4 and a state of being separated from the reversible member 4 by the reversing of the reversible member 4.

Thus, the fastener 2 can be switched between the state in which the

comb teeth

10 and 12 are closed and the state in which the

comb teeth

10 and 12 are opened by inverting the inverting member, and the fastener 2 can hold more user's hair and can be strongly fixed to the user's hair.

In the fastener 2 of each of the above embodiments, the following are disposed adjacent to each other in the longitudinal direction of the long side portion 4a: a first comb-tooth region 10A constituted by one or a plurality of first comb-teeth 10 arranged adjacently, and a second comb-tooth region 12A constituted by one or a plurality of second comb-teeth 12 arranged adjacently.

This enables the second comb-tooth region 12A having a short length adjacent thereto to reliably pick up hairs that cannot be picked up by the first comb-tooth region 10A.

In particular, in the first to third embodiments described above, since the first comb-tooth regions 10A and the second comb-tooth regions 12A are alternately arranged in the longitudinal direction of the long side portion 4a, the hair can be reliably held between the

comb teeth

10 and 12 and the reversible member 4 over substantially the entire longitudinal direction of the long side portion 4a.

Furthermore, in the fastener 2 of each of the above embodiments, since the first comb tooth 10 and the second comb tooth 12 are arranged symmetrically with respect to the center portion in the longitudinal direction of the long side portion 4a, the hair can be sandwiched between the

comb teeth

10 and 12 and the reversible member 4 in a well-balanced manner, and thus the fastener 2 can be fixed with less possibility of being displaced from the hair.

The fastener of the present invention is not only suitable for fixing the wig base described above, but also can be applied to any other fields as long as the object to be fixed is inserted between the comb teeth and the reversible member, the reversible member is reversed, and the object is sandwiched and fixed by the elastic force of the reversible member.

The embodiments of the present invention have been described, but the disclosure may be changed in details of the structure, and combinations of elements, changes in the order, and the like in the embodiments may be implemented without departing from the scope and spirit of the present invention.
