Description

Fixture

The present invention relates to a fixture for clamping and fixing an object, and particularly relates to a fixture that can be applied to a wig base with artificial hair implanted on the user's head.

In order to fix the wig base with artificial hair implanted on the user's head, a wig fixture is sometimes used. This wig fixing device is installed on the back side of the wig base net (the side in contact with the user's head) using sutures, etc., and the user’s hair is clamped by the wig fixing device. The bottom net of the wig can be fixed to the user's head. Among such fixtures for wigs, some people have proposed the use of fixtures (for example, refer to Patent Document 1) having reversal members to which a plurality of comb teeth are attached.

[Patent Document 1] International Publication No. W02007/129708

The reversing member of the wig holder described in Patent Document 1 is formed by a support piece having a plurality of comb teeth attached thereto and a pair of leg pieces protruding from both ends of the support piece. The components and the foot pieces on both sides can be drawn to the inner connecting piece to form a reversible curved shape. In the closed state in which the comb teeth are in contact with the reversing member, the reversing member is reversed to the opposite side to reverse the reversal member, thereby opening the comb teeth to the reversing member, and the user's hair can be inserted Between the opened comb and the reversing member. Then, by reversing the reversing member in the direction in which the comb teeth are closed again, the user's hair can be sandwiched between the comb teeth and the reversing member for fixing.

The fixture for a wig described in Patent Document 1 is twisted so that when the leg pieces on both sides are pulled inward by the connecting piece, the leg piece and the supporting piece are connected as the center. At this time, the length of the leg piece is shorter than the length of the support piece. Therefore, the distance that the tip of the twisted leg piece moves is short, and the amount of deformation of the reversing member is also limited.

Therefore, even if the reversing member deformed by the connecting piece is reversed, the angle at which the comb teeth are opened relative to the reversing member is relatively small. Therefore, when wearing a wig, it is difficult for the user to insert the hair between the opened comb teeth and the reversing member, and the amount of hair caught is also limited.

The purpose of the present invention is to solve the above-mentioned problems. It is to provide a fixture that can switch the comb teeth in the closed state and the comb teeth in the open state by reversing, and the fixture can be used between the comb teeth and the reverse turn Between the components, it is easy to insert hair, and more hair can be inserted.

In order to solve the above-mentioned problems, the fixture of the present invention is provided with: a reversing member, which is formed of an elastic plate-shaped member, and in an undeformed initial state, has two opposite long sides, and The two short side portions of the two short sides constitute a substantially quadrilateral planar shape, and between the long side portion and the short side portion or in the middle of the short side portion, there is a space extending from the short side portion in the direction of the long axis. Area, and has a connecting area on both sides of the aforementioned divided area; a connecting portion, which connects the overlapped connecting area by the deformation of the reversal member; and a plurality of comb teeth, one end of which is fixed in it The aforementioned long side of one side.

As described above, the present invention can provide a fixture that can switch the comb teeth to the closed state and the comb teeth to the open state by reversing. The fixture can be easily inserted between the opened comb teeth and the reversing member. Insert the hair in place, and more hair can be inserted.

[Fig. 14] A schematic plan view showing a wig equipped with the fixture of the present invention.

The fixture of Embodiment 1 of the present invention is provided with: a reversing member, which is formed of an elastic plate-shaped member, and in an undeformed initial state, has two opposing long sides and two opposing sides A substantially quadrilateral planar shape formed by two short side portions, and between the long side portion and the short side portion or in the middle of the short side portion, there is a separate area extending from the short side portion in the long axis direction, And there are connecting areas on both sides of the aforementioned divided area; a connecting portion that connects the overlapped connecting area by the deformation of the reversal member; and a plurality of comb teeth whose one end is fixed to one of them The aforementioned long side.

When there is a separate area between the long side and the short side, not only will there be a separate area between the long side and the short side where a plurality of comb teeth are fixed, there may also be unfixed There may be a separate area between the long side and the short side of the other of the plurality of comb teeth. In addition, when the short side portion has a divided area in the middle, it can have a divided area at any position of the short side portion.

In this embodiment, a reversing member fixed with a plurality of comb teeth can be deformed by bending its flat surface (wide surface) in the vertical direction, so that it can be arranged in the initial state in the connection area on both sides of the divided area. Fold together. In addition, the overlapped connecting regions can be connected to each other by using a connecting member to form a fixture. Such a fixture can be switched by reversing the reversing member to the opposite side by the user: the tips of a plurality of comb teeth contact the closed state of the reversing member, and a plurality of comb teeth The open state of the front end separated from the reversing member. When the user does not perform the reversal operation, various states can be maintained due to the elastic force of the reversing member.

Particularly, in this embodiment, since the divided area extends in the long axis direction of the short side portion, when the connecting area on both sides of the divided area is deformed in a superimposed manner, the length (the dimension in the long axis direction) is long The connecting part of the long side and the short side is twisted by rotating the center. Even if the rotation angle (torsion angle) of the side part that becomes the center of rotation and the connecting part of the side part is the same, the moving distance of the longer side of the rotating (twisted) side at the tip of the rotation becomes bigger. That is, overall, the reversing member 4 can be deformed more. As a result, the reversing member connected in the deformed state has a greater difference in angle of bending in the opposite direction after being reversed.

Therefore, in a state where the comb teeth are opened, a larger opening angle formed by the comb teeth and the reversing member can be obtained. With this, the hair can be The insert inserted into the comb teeth is fixed near the root of the reversal member, so more hair can be inserted. In addition, the opening angle when the comb teeth are in the open state is relatively large, so a large distance between the tip of the comb teeth and the reversing member can be obtained. According to this, the hair can be easily inserted between the opened comb teeth and the reversing member.

The fixture of the second embodiment of the present invention is based on the first embodiment, the length of one of the long sides in the initial state is set to W, and the state is overlapped from the initial state. When the amount of movement of the aforementioned connection area is set to D, it has a relationship of 0.15≦D/W≦0.17.

The ratio D/W of the length W of one of the long sides where the comb teeth are attached to the amount of movement D of the connection region from the initial state to the superimposed state means that the larger the value, The reversal member deforms more. Therefore, when the comb teeth are in an open state, a larger angle formed by the comb teeth and the reversing member can be obtained, and a greater distance between the tips of the comb teeth and the reversing member can also be obtained. According to this, hair can be easily inserted between the opened comb teeth and the reversing member, and more hair can also be inserted between the opened comb teeth and the reversing member.

On the other hand, once the amount of deformation increases, it is foreseeable that the durability of the reversing member will decrease, or the force required to reverse the reversal member will increase and the operability will tend to deteriorate.

Taking these considerations together, as described later, by making D/W Values falling within the range of 0.15 or more and 0.17 or less can provide a fixture that makes the hair insertion easy and the amount of hair that can be inserted are suitable, and is also good in terms of durability and operability.

In addition, the amount of movement D can be expressed by the distance between the centers of the holes in the connecting area on both sides of the divided area and the connecting holes that can be inserted by the connecting portion.

In the fixture of Embodiment 3 of the present invention, in the above-mentioned Embodiment 1 or 2, a head is provided at the free end of the comb teeth, and the head is located in the area where the long side portion of the other side exists.

In this embodiment, a part of the shaft part of the comb tooth and the head at the tip are located in the area where the other long side part exists. Therefore, when the comb teeth are closed, the shaft part of the comb tooth and the comb tooth The head, between the long side of the other side, can surely hold the hair. In addition, the comb teeth do not extend further than the long side of the other side, so when the wig is worn, there is no concern that the comb teeth interfere with the bottom net of the wig.

The fixing device of the fourth embodiment of the present invention, in the above-mentioned embodiment 1 or 2, is provided with a head at the free end of the comb teeth, and at least a part of the head is located outside the substantially quadrilateral plane shape, and The other parts of the aforementioned comb teeth are located in the aforementioned substantially quadrilateral planar area.

In this embodiment, at least a part of the head at the tip of the comb teeth can be arranged in a relatively quadrangular planar shape more outwards, and the installation When wearing a wig, it is easy to pick up the user's own hair, and by making the head as close as possible to the long side of the other side, the interference of comb teeth on the bottom net of the wig can be suppressed when wearing the wig.

The fixture of the fifth embodiment of the present invention, in the above-mentioned embodiment 3 or 4, is provided with a friction member on the other long side portion.

In this embodiment, a friction member is provided on the other long side. Therefore, when the comb teeth are in a closed state, the force to hold the hair between the comb teeth and the friction member can be increased, and the hair can be held more reliably . When the width of the other long side portion is increased and the friction member is provided in the entire area, not only the head of the comb teeth can be used, but also the shaft portion of the comb teeth. In between, keep the hair in a wider range.

The fixture of the sixth embodiment of the present invention, in any one of the aforementioned embodiments 1 to 5, has the aforementioned separation area between the long side portion and the short side portion of the other side in the initial state , The connecting area of the other long side portion is arranged to be farther away than the case where the long axis direction of the other long side portion is parallel to the long axis direction of the one of the long sides The long side of one of the foregoing.

In this embodiment, compared to the case where the long side portion of the other side is parallel to the long side portion of one of the long sides, the connection area arranged so that the long side portion of the other side is further away from the long side portion of one side. Can be reversed When the rotation member is deformed from the initial state, the inversion member is deformed to a greater extent, and the connection area can be connected.

Therefore, in the formed fixture, when the comb teeth are in an opened state, a larger angle formed by the comb teeth and the reversing member can be obtained, and the front end of the comb teeth and the reversing member can be enlarged. the distance between.

In the fixture of the seventh embodiment of the present invention, in the sixth embodiment, in the initial state, the central portion of the other long side portion is formed to be bent in a direction closer to the one long side portion .

In the initial state of this embodiment, since the central portion of the other long side portion is formed to be curved in a direction closer to the one of the long sides, the reversing member can be reversed to a greater degree and smoothly Deformed. Therefore, in the formed fixture, when the comb teeth are in the opened state, a larger angle formed by the comb teeth and the reversing member can be obtained, and the front end of the comb teeth and the reversing member can be enlarged. The distance between.

Next, the fixture of the embodiment of the present invention will be described in detail using drawings as follows.

(Description of the fixture for one embodiment)

While referring to FIGS. 1 to 3, a description of a fixture according to an embodiment of the present invention will be made. First, the main component of the fixture, that is, the reversing member, will be described in detail, and then, the entire fixture will be described in detail.

<Description of the reversal member of an embodiment>

Fig. 1 shows the planar shape of the reversing member 4 in the initial state before being deformed. From this initial state, the reversing member 4 is deformed in such a way that the connecting areas indicated by the arrows X and X'are overlapped, and by connecting the connecting member 10, the fixture 2 as shown in FIG. 2 can be formed .

The reversing member 4 is formed of a thin metal plate of elastic material. As shown in FIG. 1, the reversing member 4 is in an initial state, and has a substantially quadrangular planar shape composed of two opposing long side portions 4a and 4b and two opposing short side portions 4c and 4d. In the long side part 4a on the lower side of the figure, a plurality of comb teeth 6 are fixed there in a cantilever state. The long side portion 4a is referred to as one of the long side portions 4a, and may also be referred to as a comb tooth attachment portion 4a.

The long side portion 4b arranged at a position opposite to the long side portion 4a is referred to as the other long side portion 4b, and as described later using FIG. 2(a), since the friction member 20 is attached, it may be It is called the friction body mounting part 4b. In addition, the short side 4c connected to the right end in the illustration of one of the long side portions (comb tooth mounting portion) 4a is referred to as one of the short side portions 4c. The short side portion 4d connected to the left end of the one long side portion (comb tooth attachment portion) 4a in the figure is called the other short side portion 4d.

One of the short side portions 4c and the other short side portion 4d extend in the same direction substantially orthogonal to the long axis direction of one of the long side portions (comb tooth attachment portion) 4a. Except between the end of the other long side portion (friction body mounting portion) 4b and the end of the other short side portion 4d, one of the long sides (comb mounting portion) 4a and the other long side The portion (friction body mounting portion) 4b, one of the short side portions 4c, and the other short side portion 4d are connected to each other by ends. There is a separation area between the end of the other long side portion (friction body mounting portion) 4b and the other short side portion 4d.

If explained in a different way, the two ends of one of the long side portions (comb tooth mounting portion) 4a are connected to one of the short side portions 4c and the other short side portion 4d, and one of the short side portions The end portion on the opposite side of 4c is connected to the other long side portion (friction body mounting portion) 4b. The other long side portion (friction body mounting portion) 4b is relative to one of the long side portions (comb tooth mounting portion) 4a, from the portion connected to one of the short side portions 4c (see arrow Z ) Extends out.

Then, between the free end side end of the other long side portion (friction mounting portion) 4b and the free end side end of the other short side portion 4d, there is a separation area indicated by arrow Y. This divided area (please refer to arrow Y) extends in the direction of the long axis of the other short side 4d.

On both sides of the separated area (please refer to arrow Y), there are provided connecting areas that overlap each other when the reversing member 4 is deformed. On the free end side of the other long side portion (friction body mounting portion) 4b is provided with The connecting area indicated by arrow X, and a connecting hole 12 is provided in this connecting area (please refer to arrow X). A connecting area indicated by an arrow X'is provided at the free end side of the other short side portion 4d, and a connecting hole 14 is provided in this connecting area (please refer to the arrow X').

In this embodiment, the connection area (please refer to arrow X) of the other long side portion (friction mounting portion) 4b is longer than the long axis direction of the other long side portion (friction mounting portion). When the long axis direction of the side part (comb tooth attachment part) 4a is parallel, it is arrange|positioned so that it may be farther away from one of the long side part (comb tooth fitting part) 4a. Thereby, it is not necessary to shorten the length of the other short side portion 4d, and a larger separation area can be ensured (please refer to arrow Y).

Furthermore, as shown by arrow A, the center part of the other long side part (friction attachment part) 4b is curved in the direction approaching one of the long side parts (comb tooth attachment part). That is, the central portion is curved so as to protrude toward the inner side of the substantially quadrangular shape.

Moreover, the width dimension of the other long side part (friction body attachment part) 4b is formed larger than the other side parts 4a, 4c, and 4d. On the other long side portion (friction body mounting portion) 4b, two weight-reducing holes 22 are provided, whereby the other long side portion (friction body mounting portion) 4b is separated by 4b1, 4b2, and It is composed of the three areas indicated by 4b3. With this weight reduction hole 22, the weight of the reversing member 4 can be reduced, and the reversing member 4 can be easily deformed.

In addition, five mounting holes 24 are provided in the entire reversal member 4. By passing a suture thread or the like through the mounting hole 24, the fixture 2 can be sewn to the bottom net of the wig or the like.

The plurality of comb teeth 6 made of metal are composed of a shaft portion 6a and a head portion 6b having a larger diameter than the shaft portion 6a. The shaft portion 6a of the comb tooth 6 is attached to the end portion on the opposite side to the side with the head portion 6b, and is fixed to the reversing member 4 by welding (for example, welding). That is, the comb teeth 6 are fixed to the reversing member 4 in a cantilever state. However, the fixing method is not limited to welding, and a connecting member may be used to mechanically fix, and other arbitrary fixing methods may also be used.

The comb teeth 6 are formed in a reversible reversible member 4 in such a way that the concave-convex shape after bending faces the opposite direction. One of the states is the comb teeth 6, especially the head 6b of the comb teeth 6 and When the reversing member 4 is in contact with the closed state and is reversed to the opposite side, the comb teeth 6 can be opened from the reversing member 4 at a predetermined angle and fixed to the reversing member. 4.

Use Figure 2 and Figure 3 to illustrate this situation. Figure 2(a) shows a plan view of the state where the reversing member 4 shown in Figure 1 is deformed (curved), and the connecting regions (please refer to arrows X, X') are superimposed together to connect the connecting members .

Figures 2(b) and (c) are schematic side views as viewed from arrow B in Figure 2(a), (b) shows the comb teeth 6 in the closed state; (c) shows the comb teeth 6 in the open state. As shown in Figure 2(b), the lower part of the reversing member 4 in the figure is in a convexly curved state, that is, the comb teeth 6, especially the comb teeth where the head 6b of the comb teeth 6 is in contact with the reversing member 4 6 was closed. On the other hand, the reversing member 4 is reversed in the opposite direction, as shown in FIG. 2(c), when the upper part of the reversing member 4 in the figure becomes a convexly curved state, that is, the comb teeth 6 The comb teeth separated from the reversing member 4 are opened. These two states are maintained by the elastic force of the reversal member 4. Therefore, when the comb teeth 6 are in the open state, the hair is inserted between the comb teeth 6 and the reversing member 4, and thereafter, if the comb teeth 6 are closed, the state can still be maintained, so the hair can be reliably held ( Hold) between the comb teeth 6 and the reversing member 4.

In the embodiment shown in Fig. 3, Fig. 3(a) is the same plan view as Fig. 2(a), and Fig. 3(b) is also the same as Fig. 2(b), which shows that the comb teeth 6 are closed. The side view as viewed from arrow B in Fig. 3(a).

On the other hand, Fig. 3(c) is a side view as viewed from arrow C in Fig. 3(a) showing the comb teeth are in the open state, and clearly shows that the comb teeth 6 are in the open state. FIG. 3(c) shows that the comb teeth 6 of the length L only open the opening angle θ to the reversing member 4, and the result shows that the head 6b of the comb teeth 6 is separated from the reversing member 4 by only H distance. The length L of the comb teeth 6 is the length excluding the fixed part (welded part) on the reversing member 4, and has a relationship of H=L×Sin θ .

<Description of Deformation of Reversal Member>

In the initial state shown in FIG. 1, the position of the connecting hole 12 provided on the long side portion (friction body mounting portion) 4b of the other side can be aligned with the position of the connecting hole 14 provided on the other short side portion 4d. In this way, the reversing member 4 is deformed (bent). In this state, by inserting the connecting member 10 into the connecting hole 12 and the connecting hole 14, the overlapped connecting area (please refer to arrows X, X') can be connected Together. For example, a metal rivet can be used as the connecting member 10. After the rivet is inserted, the inserted tip can be plastically deformed. link. That is, it can be connected by "rivet fixing".

However, the connection method is not limited to this. For example, other connection members such as bolts and nuts may be used to mechanically connect, or may be connected by welding. However, the use of the connection member 10 allows the overlapped connection area to have a margin for relative movement, so it is considered to be more excellent in operability.

Next, a description will be given in more detail about the manner in which the reversing member 4 is deformed (curved) so that the positions of the connecting hole 12 and the connecting hole 14 of the reversing member 4 are aligned.

The reversing member 4 is deformed so that the reversing member 4 is bent in a direction orthogonal to the plane of the reversing member 4 in the initial state (that is, in the vertical direction of the paper surface of FIG. 1 ). At this time, because the separated area (please refer to arrow Y) extends in the direction of the long axis of the short side portion (especially the other short side portion 4d), the connecting area on both sides of the separated area (please refer to arrow Y) (Please refer to the arrows X, X') When the reversing member 4 is deformed by overlapping together, the long sides 4a, 4b with longer lengths (dimensions in the long axis direction) are connected to one of the short sides 4c The part (please refer to the arrows Z, Z') is twisted so that the center is rotated. This action is schematically represented by the dashed arrow in FIG. 1. Even if the rotation angle (torsion angle) of the side portion that becomes the center of rotation and the connecting portion of the side portion are the same, the longer the length of the side portion that is rotated (twisted) has a relatively large movement distance at the tip portion of the rotation. That is, overall, the reversing member 4 can be deformed more. Thereby, the difference in the angle at which the reversing member 4 connected in the deformed state is bent in the opposite direction at the time of reversal becomes larger.

Therefore, when the comb teeth 6 as shown in FIG. 3(c) are in an open state, a larger opening angle θ formed by the comb teeth 6 and the reversing member 4 can be obtained. Thereby, since the hair can be inserted until the comb teeth 6 are fixed to the vicinity of the comb teeth root of the reversing member 4, more hair can be inserted. In addition, since the opening angle θ of the comb teeth 6 in the open state is greater, a greater distance H between the tip of the comb teeth 6 and the reversing member 4 can be obtained. Thereby, hair can be easily inserted between the opened comb teeth 6 and the reversing member 4.

The reversing member 4 is deformed so that the distance D between the center of the connecting hole 12 and the center of the connecting hole 14 in the initial state shown in FIG. 1 becomes zero. That is, the amount of deformation from the initial state of the connection region (please refer to arrows X, X') to the superimposed state is the same as the distance D. As shown in Figure 1, when the length of one of the long sides (comb mounting portion) 4a is set to W, the amount of movement D from the initial state to the superimposed state can be compared with the length of either one The ratio of the length W of the side portion (comb tooth attachment portion) 4a is represented by D/W.

The value of D/W is an index indicating the degree of deformation of the reversing member 4, and basically the greater the value of D/W, the greater the degree of deformation. Therefore, if the formed fixture 2 has a larger D/W value, when the comb teeth 6 are opened, the opening angle θ formed by the comb teeth 6 and the reversing member 4 becomes larger, and the comb teeth 6 can be obtained. The distance H between the front end (head 6b) and the reversing member 4 is relatively large. However, as the movement amount D increases, the durability of the reversing member 4 tends to deteriorate, and the force required to reverse the reversal member 4 also increases.

Therefore, by controlling D/W in an appropriate range, the system can provide: Easily insert hair between the opened comb teeth 6 and the reversing member 4, and more hair can be inserted between the opened comb teeth 6 and the reversing member 4. The durability and operability are both fixed well With 2.

The direction of movement from the initial state to the superimposed state is the same as the long axis direction of the other short side portion 4d, so it is approximately positive with the long axis direction of one of the long side portions (comb mounting portion) 4a. Turn in the direction. However, it is not necessary to be orthogonal to each other precisely. As will be described later, the direction of movement of the connection region when the reversal member 4 is deformed should be aligned with the long axis direction of one of the long sides (comb mounting portion) 4a. The direction of intersection can be kept within a predetermined angle range.

<Describe an embodiment of the fixture>

As described above, the reversing member 4 in which the connection area is connected in a deformed state has a substantially rectangular shape formed by four sides without a divided area.

It can be seen from Fig. 2(a) that the head b of the comb tooth 6 is located in the area where the other long side part (friction body mounting part) 4b exists. Thereby, since a part of the shaft portion 6a of the comb teeth 6 and the head 6b at the front end are located in the area where the other long side portion (friction body mounting portion) 4b exists, when the comb teeth 6 are in a closed state, The hair can be reliably held between the shaft portion 6a of the comb tooth 6, the head portion 6b of the comb tooth, and the other long side portion (friction body attachment portion) 4b. In addition, since the comb teeth do not extend out more than the long side of the other side, there is no fear that the comb teeth interfere with the bottom net of the wig when the wig is worn.

However, the length of the comb teeth 6 and the position of the head b are not Limited to the situation shown in Figure 2. Fig. 10 is a schematic plan view of a fixture of another embodiment having a comb tooth shape different from that of Fig. 2. In addition, FIG. 11 is a diagram (photograph) showing an example of the fixture of the other embodiment shown in FIG. 10.

As shown in Figures 10 and 11, at least a part of the head b of the comb tooth 6 is located: it is taught by two opposite long sides 4a, 4b and two opposite short sides 4c, 4d. The substantially quadrilateral planar shape is more outside (that is, located more outside than the other long side portion 4b), and the other parts of the comb teeth 6 may be located in the substantially quadrilateral planar shape. This means that only the head b of the comb teeth 6 or only a part of the head b of the comb teeth 6 can be extended by the other long side part 4b.

If the comb teeth 6 protrude more outwards than the flat shape of a quadrilateral, it is easier to pick up your own hair when wearing a wig. On the other hand, if the protrusion is too large, the comb teeth 6 may also hook. To the bottom net of the wig. Therefore, in this embodiment, by arranging at least a part of the head 6b at the front end of the comb teeth 6 on the outside of the planar shape of the quadrangle as taught, the hair can be easily picked up when wearing a wig. In addition, the head 6b can be as close as possible to the other long side portion (friction body mounting portion) 4b, thereby preventing the comb teeth 6 from interfering with the bottom net of the wig when the wig is worn.

Moreover, not only the head b of the comb teeth 6, but also a local area close to the shaft 6a of the head 6b (for example, the area within 1 mm in length from the boundary between the shaft 6a and the head 6b), and it is also slightly quadrilateral When the planar shape is located further outside, almost the same effect as the above can be achieved.

In addition, if the outer diameter of the shaft portion 6b of the comb teeth 6 is the same, since the bending moment of the base portion of the comb teeth 6 (the part attached to the reversing member 4) is the same, the length of the comb teeth 6 is the shorter one. The force of the front end of the comb teeth 6 pushing toward the reversing member 4 side becomes relatively large. On the other hand, in the case where the length of the comb teeth 6 is long, since a larger area for installing the friction member 20 can be obtained, in this regard, the hair retention force can be improved.

In the embodiment shown in FIG. 2 or FIG. 10, both are related to the pressing force at the front end of the comb teeth 6 and the setting area (length) of the friction member 20, and it can be said that the length of the comb teeth 6 that can be balanced is adopted.

Moreover, the whole of the other long side part (friction body attachment part) 4b of the reversing member 4 is equipped with the friction member 20. As shown in FIG. The friction member 20 can be made of elastic materials with high friction coefficients such as rubber, elastomer, or urethane, such as silicon.

For example: the friction member 20 formed in the tube is inserted from the separate area (please refer to arrow Y) in the initial state and installed to cover the other long side (friction body installation portion) 4b, and then by The reversing member 4 is deformed and then connected, and the friction member 20 may be provided on the other long side portion (friction body mounting portion) 4b of the reversing member 4. However, it is not limited to this, and after the reversing member 4 is deformed and connected, the friction member 20 may be attached to the other long side portion (friction body attachment portion) 4b by means such as adhesion.

In this embodiment, since the other long side portion (friction body mounting portion) 4b is provided with the friction member 20, when the comb teeth 6 are in the closed state, it is possible to strengthen and hold the hair between the comb teeth 6 and the friction member 20. Power, but can Keep hair more surely. As described above, the other long side portion (friction body mounting portion) 4b can be obtained with a larger width dimension. Therefore, by providing the friction member 20 in the entire area, not only the head 6b of the comb tooth 6 can be used. The shaft a of the comb teeth 6 can hold hair between the comb teeth 6 and the friction member 20 in a wider range.

In addition, in the case shown in FIGS. 10 and 11, the friction member 20 exists slightly outside of the other long side portion (friction body mounting portion) 4b, so that the hair can be held on the head b of the comb tooth 6. Between and the friction member 20.

In the reversing member 4 in the initial state shown in Figure 1(a) above, the long axis direction of the other long side portion (friction body mounting portion) 4b is aligned with one of the long side portions (comb teeth). When the long axis direction of the mounting part) 4a is parallel, the connection area of the other long side part (friction body mounting part) 4b (please refer to arrow X) is arranged on the long side part farther away from one of them (comb mounting part) Part) 4a. Thereby, it is not necessary to shorten the length of the other short side portion 4d, and a larger separation area can be ensured (please refer to arrow Y).

Furthermore, since a larger separation area can be ensured (please refer to arrow Y), when the reversing member 4 is deformed from the initial state, the reversing member 4 can be deformed more and the connecting area (please refer to the arrow X, X') are connected. Thereby, in the formed fixture 2, when the comb teeth 6 are in an open state, a larger opening angle θ formed by the comb teeth 6 and the reversing member 4 can be obtained, and a larger comb teeth can be obtained. 6 The distance H between the front end (head 6b) and the reversing member 4.

In addition, in the reverse of the initial state shown in Figure 1(a) above The turning member 4 is formed by bending the central portion of the other long side (friction body mounting portion) 4b in a direction close to one of the long sides (comb mounting portion) 4a (please refer to arrow A), Therefore, the reversing member 4 can be deformed in a manner that reverses more greatly and smoothly. Therefore, in the formed fixture 2, when the comb teeth 6 are in an open state, a larger opening angle θ formed by the comb teeth 6 and the reversing member 4 can be obtained, and a larger comb teeth 6 can be obtained. The distance H between the front end (head 6b) and the reversing member 4.

As a metal material constituting the reversing member 4 or the comb teeth 6, a metal material such as stainless steel, carbon steel, aluminum, copper, and titanium can be used. In addition, it can also be coated on the surface of the metal sheet, especially the coating on the metal surface is very effective to prevent allergy to metal. In order to improve the tactile feeling during wearing, a rubber-touch coating film can be applied, and other required materials can be coated according to its purpose.

If described based on the dimensions of the reversing member 4, the thickness can be 0.5~2mm, the length of the long side corresponding to W can be 20~50mm, or the length of the short side can be exemplified as 15~30mm. In addition, the length of the comb teeth 6 may be 10-30 mm, and the outer diameter of the shaft portion 6a of the comb teeth 6 may be 0.3-2 mm. However, these sizes are examples for wigs, and other sizes can be used according to different uses.

<Description of Reversal Member in Other Embodiments>

Next, while referring to FIGS. 4 and 5, the reversing member 4 according to another embodiment of the present invention will be described. Figure 4 and Figure 5 respectively show A schematic plan view of the reversing member 4 according to another embodiment of the present invention.

<Description of the embodiment shown in Figure 4>

The reversing member 4 of the other embodiment shown in FIG. 4 has a shape similar to that of the reversing member 4 of the embodiment shown in FIG. 1. However, the difference is: the reversing member 4 shown in Fig. 1 is located at the end (please refer to the arrow X) of the other long side (friction body mounting portion) 4b and the other short side on the upper side of the drawing. There is a separate area between the ends of the part 4d (please refer to arrow X') (please refer to arrow Y); and the reversing member 4 shown in Figure 4 is located on one of the long sides of the lower side of the drawing (Friction body mounting part) There is a separation area (please refer to arrow Y) between the end of 4a (please refer to arrow X') and the end of the other short side portion 4d (please refer to arrow X). Therefore, the reversing member 4 of the other embodiment shown in FIG. 4 has a structure which connects the other long side part (friction body attachment part) 4b and the other short side part 4d.

When deforming (bending) the reversing member 4, basically the same as the reversing member 4 of the embodiment shown in FIG. 1, due to the long sides 4a, 4b having a longer length (dimension in the longitudinal direction), It is twisted by rotating the connection part with one of the short sides 4c (please refer to arrows Z, Z') as the center (please refer to the dotted arrow), so the reversing member 4 can be made larger Deformed.

In addition, the other shapes are the same as the reversing member 4 of the embodiment shown in FIG. 1, so a more detailed description thereof is omitted.

<Description of the embodiment shown in Figure 5>

The reversing member 4 of the other embodiment shown in FIG. 5, in an initial state, has: an outline consisting of two opposing long side portions 4a, 4b and two opposing short side portions 4c, 4d The planar shape of a quadrilateral and the point that a plurality of comb teeth 6 are fixed to one of the long sides 4a on the lower side of the drawing is the same as the reversing member 4 of the embodiment shown in FIGS. 1 and 4. However, in the middle of the other short side portion 4d, there is a separate area extending in the direction of the long axis of the short side portion 4d (please refer to arrow Y), which is similar to the embodiment shown in FIGS. 1 and 4 The reversal member 4 is different. Therefore, the long side parts 4a, 4b and the short side parts 4c, 4d are all connected by ends.

When deforming (bending) the reversing member 4, basically the same as the reversing member 4 of the embodiment shown in FIG. 1, the long sides 4a, 4b having a longer length (dimension in the longitudinal direction) are It is twisted by rotating around the connection part (please refer to arrows Z, Z') with one of the short sides 4c (please refer to the dotted arrow), so the reversing member 4 can be deformed more greatly .

In addition, other shapes and the like are substantially the same as the reversing member 4 of the embodiment shown in FIGS. 1 and 4, so a more detailed description thereof is omitted.

(Description of the relationship between the D/W ratio and the distance H when the comb teeth are open)

Next, referring to FIGS. 6 to 9, the appropriate range of the above D/W ratio will be explained. Fig. 6 shows: a view of Example 1 of the fixture with the reversal member according to an embodiment of the present invention shown in Fig. 1 (photo sheet). Fig. 7 shows a view (photograph) of Example 2 of a fixture having a reversal member according to another embodiment of the present invention shown in Fig. 5. Fig. 8 shows a diagram (photograph) of Example 3 of a fixture having a reversal member according to another embodiment of the present invention shown in Fig. 5. Fig. 9 shows a diagram (photograph) of Example 4 of the fixture having the reversal member according to one embodiment of the present invention shown in Fig. 1.

In Example 1 shown in Fig. 6, the length W of one of the long sides (comb tooth mounting portion) of the reversing member in the initial state is 40.5mm, and the value of the movement amount D when the reversing member is deformed It is 6.85mm. Therefore, the ratio of the movement amount D to the length W of the long side portion (comb tooth attachment portion), that is, the ratio of D/W becomes 0.619. At this time, the distance (the maximum distance) H between the front end of the comb teeth in the open state and the reversing member (the comb teeth in the center becomes the maximum distance) is 9.3 mm. The length L of the comb teeth other than the welding portion is 11 mm, so the opening angle θ formed by the shaft portion of the comb teeth and the reversing member is 58 degrees.

That is, in Embodiment 1 shown in FIG. 6, the opening height H of the opened comb teeth for inserting the hair is 9.3 mm, and the opening angle θ is 58 degrees. In fact, when a user performs a hair insertion test, the opening height H that can easily insert the hair is obtained, and a good judgment result of the opening angle θ at which a sufficient amount of hair can be inserted can be obtained. In addition, even if a test in which the inversion member is repeatedly inverted, a good judgment result can be obtained in terms of durability and operability.

In Example 2 shown in FIG. 7, the length W of one of the long sides (comb tooth mounting portion) of the reversing member in the initial state is 35.5mm, the value of the movement D when deforming the reversal member is 4.9mm. Therefore, the ratio of the movement amount D to the length W of the long side portion (comb tooth attachment portion), that is, the D/W ratio, is 0.138. At this time, the distance (maximum distance) H between the tip of the comb tooth in the open state and the reversing member is 4.9 mm. The length L of the comb teeth other than the welding portion is 16 mm, so the opening angle θ formed by the shaft portion of the comb teeth and the reversing member is 18 degrees.

That is, in Embodiment 2 shown in FIG. 7, the opening height H of the opened comb teeth for inserting hair is 4.9 mm, and the opening angle θ is 18 degrees. In fact, when the user performs a hair insertion test, it can be known that although the hair can be inserted, it does not reach the level of Example 1, and the amount of hair inserted does not reach the level of Example 1.

That is, although it is practically usable, it is impossible to obtain the same good judgment result as Example 1 in terms of the ease of hair insertion and the amount of hair that can be inserted. On the other hand, after the test of repeatedly reversing the reversing member, a good judgment result similar to that of Example 1 was obtained in terms of durability and operability.

In Example 3 shown in FIG. 8, in the initial state, the length W of one of the long side portions (comb tooth attachment portion) is 48.5 mm, and the value of the movement amount D when the reversing member is deformed is 5.55 mm. Therefore, the ratio of the movement amount D to the length W of the long side portion (comb tooth attachment portion), that is, the ratio D/W, is 0.114. At this time, the distance (maximum distance) H between the tip of the comb tooth in the open state and the reversing member is 4.7 mm. The length L of the comb teeth other than the welding portion is 16 mm, so the opening angle θ formed by the shaft portion of the comb teeth and the reversing member is 17 degrees.

That is, in Example 3 shown in FIG. 8, the opening height H of the opened comb teeth for inserting hair is 4.7 mm, and the opening angle θ is 17 degrees. In fact, when the user performs a hair insertion test, it can be known that although the hair can be inserted, it does not reach the level of Example 1, and the amount of hair inserted does not reach the level of Example 1.

That is, although it is practically usable, it is impossible to obtain the same good judgment result as Example 1 in terms of the ease of hair insertion and the amount of hair that can be inserted. On the other hand, after the test of repeatedly reversing the reversing member, a good judgment result similar to that of Example 1 was obtained in terms of durability and operability.

In Example 4 shown in FIG. 9, the length W of one of the long sides (comb mounting portion) of the reversing member in the initial state is 40.5mm, and the ratio of the amount of movement D when the reversing member is deformed It is 7.0mm. Therefore, the ratio of the movement amount D to the length W of the long side portion (comb tooth attachment portion), that is, the D/W ratio, is 0.173. At this time, the distance (maximum distance) H between the tip of the comb teeth in the open state and the reversing member is 10.3 mm. The length L of the comb teeth other than the welding portion is 11 mm, so the opening angle θ formed by the shaft portion of the comb teeth and the reversing member is 69 degrees.

That is, in Embodiment 4 shown in FIG. 9, the opening height H of the opened comb teeth for inserting hair is 10.3 mm, and the opening angle θ is 69 degrees. In fact, when the user performs a hair insertion test, it can be seen that, as in Example 1, it has an opening height H that allows hair to be easily inserted, and an opening angle θ that can insert a sufficient amount of hair. However, when the experiment of reversing the reversing member repeatedly, it can be known that: Durability and operability did not reach the level of Example 1.

In other words, in terms of the ease of hair insertion and the amount of hair that can be inserted, the same good judgment results as in Example 1 can be obtained, but in terms of durability and operability, the same results as in Example 1 cannot be obtained. The same good judgment result.

The above results are summarized into the following chart.

In other words, only Example 1 with D/W=1.169 was obtained in terms of the ease of insertion and the amount of hair that can be inserted, as well as durability and operability.

<Relationship between D/W and H>

According to the data obtained above, the ratio of D/W and the distance (maximum distance) H between the front end of the comb teeth and the reversing member can be expressed by the following approximate formula (cubic formula).

H=11,160×(D/W) ³ -2,269×(D/W) ² +4,760×(D/W)+12.3

The relationship between D/W and H expressed by this formula is shown in the graph of Fig. 12 together with the above four measured values. Figure 12 shows: in the present invention In the fixture, the ratio D/W between the amount of movement D that deforms the reversing member and the length W of one of the long sides thereof is a graph showing the relationship between the distance (maximum distance) H when the comb teeth are opened.

<The relationship between D/W and θ>

Similarly, according to the data obtained above, the ratio of D/W and the opening angle θ of the comb teeth from the reversing member can be expressed by the following approximate formula (cubic formula).

θ=322,072×(D/W) ³ -11,289×(D/W) ² +13,103×(D/W)+487

The relationship between D/W and θ expressed by this formula is shown in the graph of Fig. 13 together with the above four measured values. Fig. 13 shows: in the fixture of the present invention, the ratio D/W between the amount of movement D for deforming the reversing member and the length W of one of the long sides thereof is related to the opening angle θ when the comb teeth are opened chart.

The distance H depends not only on the opening condition of the comb teeth, but also on the length of the shaft portion of the comb teeth, so it can be said that the opening angle θ can more objectively express the opening condition of the comb teeth. Using comb teeth with various opening angles, assuming the actual condition of wearing the wig on the head, in the test of inserting the hair between the comb teeth and the reversing member, it can be found that: when the opening angle θ is 25 degrees or more It is good in terms of the ease of hair insertion and the amount of hair inserted between the comb teeth and the reversing member. This result is consistent with the data of the above 4 experiments.

Furthermore, when the opening angle θ is more than 35 degrees, especially more than 40 degrees, it can be seen that it is better in terms of the ease of hair insertion and the amount of hair inserted between the comb teeth and the reversing member .

On the other hand, it is also known that even if the opening angle θ has an opening angle of more than 60 degrees, there is almost no effect on the ease of hair insertion and the amount of hair that can be inserted in practice. Furthermore, it is also known that, as shown in the above-mentioned Example 4, if the opening angle θ exceeds 60 degrees, the durability and operability of the reversing member tend to deteriorate.

之關係為佳。 Therefore, in the wig holder of the present invention, as the ratio D/W between the amount of movement D that deforms the reversing member and the length W of one of the long sides, according to the graph in FIG. 13, it can be seen that: With an opening angle θ corresponding to 25 degrees above 60 degrees

The relationship is better.

之關係為更佳。 Furthermore, according to the graph in Fig. 13, it can be seen that the opening angle θ corresponds to the range of about 40 degrees to 60 degrees.

The relationship is better.

D/W

0.17(式1)之關係的話，在將插入毛髮之容易度、可插入之毛髮量、耐久性以及操作性上的方面皆為良好，且若具有0.16

D/W

0.17(式2)之關係的話，在插入毛髮之容 易度及可插入之毛髮量上更佳，而在耐久性及操作性的方面還是良好。 As mentioned above, it can be known that if there is 0.15

D/W

With the relationship of 0.17 (Equation 1), the ease of inserting hair, the amount of hair that can be inserted, durability and operability are all good, and if it has 0.16

D/W

With the relationship of 0.17 (Equation 2), the ease of hair insertion and the amount of hair that can be inserted are better, and durability and operability are still better.

D/W

0.17之關係。因此，係與實施例1同樣地，圖11所示之實施例亦可得知：在插入毛髮之容易度、可插入之毛髮量、耐久性及操作性皆為優異。 Furthermore, in the example shown in FIG. 11, the ratio of D/W is 0.169 as in Example 1. In addition, the distance (maximum distance) H between the front end of the comb teeth in the open state and the reversing member is 13 mm. The length L of the comb teeth other than the welding portion is 16 mm, so the opening angle θ formed by the shaft portion of the comb teeth and the reversing member becomes 54 degrees. That is, the opening angle θ is about 40 degrees or more and 60 degrees or less, with 0.16

D/W

0.17 relationship. Therefore, as in Example 1, the example shown in FIG. 11 can also be found to be excellent in the ease of hair insertion, the amount of hair that can be inserted, durability and operability.

From the initial state to the superimposed state, although the connection area has only moved by the amount of movement D, since the direction of movement is along the long axis of the short side, it is roughly orthogonal to the long axis of the long side. . However, it is not necessary to accurately orthogonalize. For example, when the amount of movement in the direction that is accurately orthogonal to 90 degrees is set to 100% (Sin90 degrees), the case of 80 degrees is set to 98% (Sin80 degrees). The case of 70 degrees is set to about 94% (Sin70 degrees). It can be considered that if it is within this range, the above (conditional expression 1) and (conditional expression 2) can be applied substantially. Therefore, it can be considered that the above-mentioned (conditional expression 1) and (conditional expression) can be applied if the moving direction of the connecting region shown by the moving distance D has an angle of 70 degrees or more with respect to the long axis direction of the long side portion 2).
