The present invention relates to a fastener for a wig to fix the wig to a wearer's head. More specifically, the present invention relates to a fastener for a wig which can facilitate removal of the wig, and a wig which uses this fastener.
In the case that wearer's own hairs remain, for example, a fastener described in the Patent document 1 has been widely used, as a method for fixing a wig to the wearer's head. This type of fastener is provided with comb teeth which clamp and fix the own hairs at one longer side of a frame with inverting ability. The fastener is connected to a rear side of the wig such that the comb teeth are positioned in parallel to an extending direction of the own hairs. In this case, since the extending direction of the comb teeth is parallel to the extending direction of the own hairs, there is a problem such that a clamping strength of the comb teeth to clamp the own hairs is low, and a stable fixing strength cannot be obtained if enough amount of own hairs do not exist.
Further, if the head moves in the lateral direction to the extending direction of the comb teeth, the own hairs will easily slip from the comb teeth. On the contrary, if the head moves in parallel to the extending direction of the comb teeth, the own hairs may be pulled by the comb teeth, and the wearer tends to feel pain. Further, there is also a case such that hair loss progresses by using the fastener at the same position for a long time.
In order to improve the above-mentioned defects, there is disclosed a fastener for a wig which is provided with comb teeth at left and right shorter sides of a frame with inverting ability in Patent documents 2 and Patent documents 3.
In the fastener described in Patent document 2, 3, since the fastener is connected to a rear side of the wig such that the comb teeth are positioned in perpendicular to an extending direction of the own hairs, the pain caused due to the pulled hairs will be reduced compared to the case of Patent document 1. However, each of the fasteners of Patent documents 2, 3 has the following problems because it has a construction such that two framing portions forming the left and right shorter sides to which the comb teeth are attached are connected together and integrated at the center position thereof.
Thus, when a wig is removed from the head, it is necessary to reverse the frames of the fastener to release the condition that the comb teeth clamp the own hairs. At this moment, since the fastener has the construction such that two framing portions at left and right are connected at one central position, it is impossible to reverse both framing portions by one operation of reversing the frame, and thereby requiring at least two revering operations. Otherwise, in many cases, the comb teeth at the intended side do not open due to loading strength or the loading position of the framing portion. Therefore, the wearer tends to feel the attaching and removing operation of the wig to be troublesome (this issue will be explained in the description of embodiments with referring to
Patent document 1: JU S56(1981)-23294A
Patent document 2: JP 2011-149110A
Patent document 3: JP 2013-40430A
The present invention is made according to the above-mentioned actual status of the prior arts. A purpose of the present invention is specifically to enhance operability at removing a wig from the head, relating to a fastener for a wig which is connected to the wig such that comb teeth thereof are positioned in approximately perpendicular to an extending direction of own hairs of a wearer.
A fastener for a wig according to the present invention is connected to an inside surface of the wig and clamps wearer's own hairs, and thereby fixing the wig to a wearer's head, and comprises two approximately U-shape members. Each of the approximately U-shape members is configured of a “comb teeth fixed piece to which comb teeth are fixed”, and “two curved elastic leg portions which extend from both ends of the comb teeth fixed piece in the same direction which is approximately perpendicular to 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. An open position and a closed position may be selected by reversing the bending direction of the curved elastic leg portions, in the open position, the “comb teeth are raised away from the curved elastic leg portions”, and in the closed position, the “comb teeth extend along the curved elastic leg portions”.
According to the fastener for a wig according to the present invention which has the above-mentioned configuration, 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 the curved elastic leg portions are overlapped each other. Accordingly, both of the approximately U-shape members have both a high elastic deformation capability and a high integrity. Therefore, during an operation that the fastener for a wig is 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. In other words, the situation such that “only one of the approximately U-shape members is reversed, which results in requiring two of reversing operations” does not occur.
Accordingly, during the reversing operation, it is possible to reverse the fastener for a wig certainly only by one easy reversing operation without bothering about details relating to how to touch the fastener with fingers, a degree of applied force and a direction thereof (it is possible to remove a wig easily and certainly only by one reversing operation).
Embodiments according to the present invention are hereinafter described with referring to attached drawings.
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 (
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
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.
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
In the “closed position” of
When the wig is removed, the “open position” of
<<Effect in Comparison with Prior Example>>
The effect of the present invention is described in comparison with referring to
According to the fastener S for a wig according to the present invention (
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.
On the contrary, in the fastener for a wig of the prior example (
In the embodiment illustrated in
Taking the above-mentioned issues into account, it is preferable to provide adequate number such as two or more of the connecting points accordingly.
In the embodiment illustrated in
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
Taking the above-mentioned issues into account, the configuration such that the connecting holes 16, 17 exist inside as illustrated in
In the embodiment illustrated in
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.
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
The cylindrical member 30 may be made of any material. It is, however, preferable to use silicon, rubber or other elastic materials.
As being understood in
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.
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.
