FASTENER FOR WIG AND WIG USING THE SAME

Abstract

A fastener for a wig having two approximately U-shape members, each configured of a comb teeth fixed piece, and two curved elastic leg portions which extend from both ends of the comb teeth fixed piece. The two approximately U-shape members are connected to each other at a plurality of connecting points located away from each other in a direction that each of the curved elastic leg portions extends under the condition that opening portions of the approximately U-shape members face each other and the curved elastic leg portions are overlapped each other. Accordingly, both members have both a high elastic deformation capability and a high integrity. Therefore, during the operation such that the fastener for a wig are reversed by fingers, if one of the approximately U-shape members is reversed, the other approximately U-shape member is always reversed at the same time, one reversing operation is always enough.

DESCRIPTION OF EMBODIMENT

[0021] Embodiments according to the present invention are hereinafter described with referring to attached drawings. FIG. 1 illustrates two approximately U-shape members 10 which form a fastener S for a wig according to one embodiment. In this embodiment, one fastener S for a wig is configured of two approximately U-shape members 10 which are identical. Therefore, a configuration will be hereinafter described only for one approximately U-shape member 10.

<<Configuration of Approximately U-Shape Member>>

[0022] The approximately U-shape member 10 is configured of a comb teeth fixed piece 11 to which comb teeth 20 are fixed, and two curved elastic leg portions 12, 13 which extend from both ends of the comb teeth fixed piece 11 in the same direction which is approximately perpendicular to the comb teeth fixed piece 11. The curved elastic leg portions 12, 13 are not flat members. The curved elastic leg portions 12, 13 have shapes positioned in a hypothetical curved surface, and it may selectively take an “open position” and a “closed position” as described below (FIGS. 2A and 2B).

[0023] Firstly, opening portions 15 of the two approximately U-shape members 10, 10 face each other, and then the condition such that the curved elastic leg portions 12, 13 are overlapped each other is made. Under this condition, the curved elastic leg portions 12, 13 are connected to each other at a plurality of connecting points (in this embodiment, connecting holes 16, 17) located away from each other in a direction that each of the curved elastic leg portions 12, 13 extends. This condition is shown in FIG. 2A.

[0024] At the connecting holes 16, 17, for example, the curved elastic leg portions 12, 13 which are overlapped each other are connected with using caulking pieces such as rivets (not shown). Accordingly, one fastener S for a wig is configured with using the two approximately U-shape members 10.

<<Open Position and Closed Position>>

[0025] The two approximately U-shape members 10 and comb teeth 20 are made of an elastic material such as a metallic material or others. Therefore, the fastener S for a wig may selectively take two conditions such that a bending direction of the curved elastic leg portions is different, as shown in the “open position” of FIG. 2A and the “closed position” of FIG. 2B, by adding an appropriate external force with fingers or the like, and thereby reversing the curved elastic leg portions. In FIG. 2B, the connecting portion (a central portion of the drawing) of the two curved elastic leg portions is schematically illustrated by the dashed line.

[0026] In the “closed position” of FIG. 2B, the comb teeth 20 extend almost along the curved elastic leg portions 12, 13. This indicates the condition that the wig is fixed to the own hairs of the wearer. While FIG. 3B schematically illustrates the condition that the fastener S for a wig is connected to the inner surface of the wig base, the wig is fixed to the head by making the fastener S for a wig clamp the own hairs when the fastener S for a wig is at the “closed position (In FIG. 3B, the wig and the head are illustrated as located apart from each other for a clear illustration).

[0027] When the wig is removed, the “open position” of FIG. 2A is taken by reversing the fastener S for a wig. In this position, the comb teeth 20 are raised away from the curved elastic leg portions 12, 13. As illustrated in the corresponding FIG. 3A, when the fastener S for a wig is in the “open position”, the own hairs which have been clamped are released, and therefore the wig may be removed from the head.

<<Effect in Comparison with Prior Example>>

[0028] The effect of the present invention is described in comparison with referring to FIG. 4. FIG. 4A illustrates the fastener S for a wig shown in FIG. 2A again. On the contrary, FIG. 4B illustrates a fastener for a wig of Patent document 3 (JP 2013-40430A) described in the front portion of the specification (Patent document 3 is the prior application of the applicant).

[0029] According to the fastener S for a wig according to the present invention (FIG. 4a), the two approximately U-shape members 10, 10 are connected to each other at the plurality of connecting points along the longitudinal direction (extending direction) under the condition that the curved elastic leg portions are overlapped each other. Accordingly, both of the approximately U-shape members 10, 10 have both a high elastic deformation capability and a high integrity. Therefore, during the operation such that the fastener S for a wig are reversed by fingers, if one of the approximately U-shape members 10 is reversed, the other approximately U-shape member 10 is always reversed at the same time.

[0030] In other words, the situation such that “only one of the approximately U-shape members is reversed, which results in requiring two reversing operations” does not occur.

[0031] On the contrary, in the fastener for a wig of the prior example (FIG. 4B), since two members at left and right simply come into contact and connected at one position, the two members are highly independent. Due to such configuration, it is possible that only one of the member is reversed according to the degree of applied force during the reversing operation. In this case, the wearer finally feels such operation to be troublesome because two reversing operations are required.

<<Number of Connecting Point>>

[0032] In the embodiment illustrated in FIG. 1 and FIG. 2, two of the connecting points (connecting holes 16, 17) are provided along the longitudinal direction (extending direction) of the curved elastic leg portions 12, 13 of the approximately U-shape members 10 (Since two connecting points exist per one leg portion, total four connecting portions exist). From the view point of enhancing integrity of the two approximately U-shape members 10, a large number of the connecting points will be preferable. Therefore, three or more of the connecting points may be provided. On the contrary, if too many connecting points are provided, an adequate elastic deformation (reversing property of the fastener S for a wig) will be lost.

[0033] Taking the above-mentioned issues into account, it is preferable to provide adequate number such as two or more of the connecting points accordingly.

<<Arrangement of Connecting Point>>

[0034] In the embodiment illustrated in FIG. 1 and FIG. 2, protruding portions 6, 7 which protrude inwardly and face each other are provided in two of the curved elastic leg portions 12, 13 of the approximately U-shape members 10. The connecting holes 16, 17 are formed in the protruding portions 6, 7, and the connecting holes 16, 17 work as the connecting points of the two curved elastic leg portions.

[0035] Accordingly, the connecting points exist at the offset position located inside the curved elastic leg portions 12, 13 themselves, which brings the following advantage. The advantage is hereinafter described with referring to FIG. 5.

[0036] FIG. 5 schematically illustrates relative positions of the connecting holes 16, 17 in the fastener S for a wig after assembly. The two approximately U-shape members 10 which are overlapped together are shown as a simple frame work, and an illustration of the comb teeth 20 are omitted. FIG. 5(A) corresponds to the embodiment of FIGS. 1,2, and the connecting holes 16, 17 exists inside.

[0037] FIG. 5(B) illustrates the case that the connecting holes 16,17 are provided in the connecting portions (not illustrated) which extrude outwardly. In this case, it is not preferable because it may be considered that the own hairs entwine the protruding parts, or the scalp is injured. Further, in the case that a cylindrical member 30 such as a silicon tube is installed (described later with referring to FIG. 6), the cylindrical member 30 tends to be damaged. Therefore, it is not preferable in this point.

[0038] FIG. 5(C) illustrates the case that the connecting holes 16, 17 are located within the members of the curved elastic leg portions 12, 13 themselves. In this case, it is not preferable in the view point of durability because a large load is applied to the curved elastic leg portions 12, 13 due to repeat of the reversing operation. Further, it is not preferable because it cannot utilize elastic deforming property of the curved elastic leg portions 12, 13 themselves, and the force for holding the hairs becomes weak.

[0039] Taking the above-mentioned issues into account, the configuration such that the connecting holes 16, 17 exist inside as illustrated in FIG. 5(A) is most preferable. While the configurations of FIG. 5(B) and FIG. 5(C) are inferior to the configuration of FIG. 5(A) in the above-mentioned points, it may obtain the effect such that the reversing operability is improved as described with referring to FIG. 4.

<<Connecting Mode at Connecting Point>>

[0040] In the embodiment illustrated in FIG. 1 and FIG. 2, the connecting holes 16, 17 are applied as the connecting points, and a fixing work is performed by inserting the caulking pieces such as rivets (not illustrated) and deforming them. However, in the present invention, the curved elastic leg portions 12, 13 which are overlapped each other are connected and fixed in anyway at the plurality of connecting points located apart from each other along the longitudinal direction (extending direction) of the curved elastic leg portions 12, 13.

[0041] For example, fixing work may be performed by winding the string to the connecting holes 16, 17 or by using threaded fasteners. Further, fixing work may be performed at the plurality of points located apart from each other by using adhesive agent or by spot welding without using the connecting holes.

<<Cylindrical Member 30>>

[0042] FIG. 6 illustrates a fastener S′ for a wig according to another embodiment of the present invention. This fastener S′ for a wig is different from the fastener S for a wig illustrated in FIGS. 1, 2 in the point of adding a cylindrical member 30, and the other points are the same.

[0043] The cylindrical member 30 is inserted onto the curved elastic leg portions 12, 13 which are overlapped each other and fixed together, in the manner of surrounding the curved elastic leg portions 12, 13. In the case that the cylindrical member 30 exists, if the fastener S′ for a wig is in the “closed position” as illustrated in FIG. 2B, a force of clamping the own hairs between the comb teeth 20 and the cylindrical member 30 becomes larger, and thereby fixing the wig stably.

[0044] The cylindrical member 30 may be made of any material. It is, however, preferable to use silicon, rubber or other elastic materials.

[0045] As being understood in FIGS. 3A,B, an inner surface of the wig base is located at the upper side of the fastener for a wig during use of the wig. Therefore, even if the cylindrical member 30 does not exist, it may obtain the function of clamping the own hairs by the inner surface (or any member attached to the inner surface) of the wig base together with the comb teeth 20. Accordingly, the cylindrical member 30 is not a mandatory element, but it is preferable element to be installed.

Other Embodiment

[0046] In the illustrated embodiments, the fastener for a wig is configured by using, and connecting and fixing two of the same (one kind of) two approximately U-shape members 10. In this case, it is advantageous in the view point of a simplified manufacturing process and a cost down because it is enough to prepare only one kind of the member.

[0047] However, it is not necessary to use two approximately U-shape members which are completely the same. It is possible to use two approximately U-shape members which are different from each other as far as the fastener for a wig which is substantially similar to those described so far by combining these two approximately U-shape members.
