[0008] Preferred embodiments will be described in detail below, with reference to drawings as appropriate.

[0009] The hair extension device 1 shown in Figures 1A and 1B is a device for securing a wig or the like to the head. Here, "hair extension" refers to hair that is secured to the head by the hair extension device 1, regardless of whether it is human hair or synthetic hair.

[0010] The hair extension device 1 shown in Figures 1A and 1B comprises a first sheet 2 and a second sheet 3. The first sheet 2 and the second sheet 3 are formed by folding a single sheet 4. Sheet 4 is a sheet that can be deformed to conform to the shape of the head. The material of sheet 4 is not particularly limited, but examples include polyurethane, polyester, silk, etc. One end 2E of the first sheet 2 and one end 3E of the second sheet 3 are formed by a fold 4F of sheet 4.

[0011] The prosthetic hair fixation device 1 has an opening 5. The opening 5 is formed by cutting a portion of the fold 4F of the sheet 4. The opening 5 is located on a line extending from one end 2E of the first sheet 2 and one end 3E of the second sheet 3.

[0012] In Figure 1A, the double-headed arrow W2 represents the width of the first sheet 2. Width W2 is the distance from one end 2E to the other end 2F. The double-headed arrow W3 represents the width of the second sheet 3. Width W3 is the distance from one end 3E to the other end 3F. In this prosthetic hair fixation device 1, widths W2 and W3 are the same size. In Figure 1B, the double-headed arrow T represents the thickness of sheet 4. This thickness T is also the thickness of the first sheet 2 and the second sheet 3. Note that the thickness of the first sheet 2 and the second sheet 3 may be different.

[0013] In Figure 1A, the double arrow HL represents the length of the opening 5. The double arrow HW represents the width of the opening 5. The double arrow C1 represents the connection length between the first sheet 2 and the second sheet 3 from one end of edge 2E of the first sheet 2 to the opening 5. The double arrow C2 represents the connection length between the first sheet 2 and the second sheet 3 from the other end of edge 2E of the first sheet 2 to the opening 5.

[0014] Figures 2A and 2B show the state of use of the hair extension device 1. As shown in Figure 2B, in the hair extension device 1, human hair 6, which serves as the hair extension, is fixed to the surface 2A of the first sheet 2. The human hair 6 is fixed with the root towards the edge 2E and the tip towards the edge 2F. This human hair 6 is directly bonded and fixed to the first sheet 2, but the first sheet 2 may be sewn or bonded to a net or cloth to which the human hair 6 is fixed.

[0015] As shown in Figures 2A and 2B, the natural hair 8 growing on the head 7 is passed through the opening 5. As shown in Figure 2A, the natural hair 8 that has passed through the opening 5 is aligned along the length of the opening 5. As shown in Figure 2B, the natural hair 8 that has not passed through the opening 5 is kept away from the hair extension fixture 1. As shown in Figures 2A and 2B, the edge 2E of the first sheet 2 is in contact with the head 7. As shown in Figure 2B, the natural hair 8 that has passed through the opening 5 is sandwiched between the first sheet 2 and the second sheet 3. The back surface 2B of the first sheet 2 and the back surface 3B of the second sheet 3 are bonded together with adhesive, sandwiching the natural hair 8 between them. This adhesive bonds the natural hair 8 to the back surface 2B of the first sheet 2 and the back surface 3B of the second sheet 3.

[0016] Figure 3A shows a cross-section of the prosthetic hair fixation device 1 along the line segment IIIA-IIIA in Figure 2A. In the cross-section of Figure 3A, the natural hair 8 is not sandwiched between the back surface 2B of the first sheet 2 and the back surface 3B of the second sheet 3. The back surface 2B of the first sheet 2 and the back surface 3B of the second sheet 3 are bonded together with adhesive.

[0017] In Figure 3B, the hair extension device 1 is lying flat along the head 7, along with the surrounding natural hair 8. The human hair 6 fixed to the hair extension device 1 also extends along the head 7, along with the surrounding natural hair 8.

[0018] Here, the method of attaching the wig fixture 1 shown in FIGS. 2A and 2B will be described. As shown in FIG. 2B, a wig fixture 1 with human hair 6 fixed to the first sheet 2 is prepared. At the head 7 of the person wearing the wig fixture 1, a part of the natural hair 8 is separated from other natural hair 8. The separated part of the natural hair 8 is pulled out from the opening 5. The edge 2E of the first sheet 2 and the edge 3E of the second sheet 3 are brought close to the head 7 around the part of the natural hair 8 pulled out from the opening 5. An adhesive is applied to the back surface 2B of the first sheet 2 and the back surface 3B of the second sheet 3. With the edge 2E of the first sheet 2 and the edge 3E of the second sheet 3 in contact with the head 7, the back surface 2B of the first sheet 2 and the back surface 3B of the second sheet 3 are adhered with a part of the natural hair 8 pulled out from the opening 5 sandwiched therebetween. In this way, the wig fixture 1 is put into the use state shown in FIGS. 2A, 2B and 3A.

[0019] Furthermore, the wig fixture 1 and the human hair 6 are arranged along the head 7 together with the natural hair 8. In this way, the wig fixture 1 is put into the use state shown in FIG. 3B. Further, an adhesive may be applied to the front surface 3A of the second sheet 3, and the front surface 3A may be adhered to the head 7.

[0020] This wig fixture 1 has an opening 5 on the line along which the edge 2E of the first sheet 2 and the edge 3E of the second sheet 3 extend. Around the natural hair 8 passed through the opening 5, the edge 2E of the first sheet 2 and the edge 3E of the second sheet 3 are located near the head 7. When the edge 2E of the first sheet 2 and the edge 3E of the second sheet 3 approach the head 7, this wig fixture 1 can suppress other natural hair 8 not passed through the opening 5 from interfering with the first sheet 2 and the second sheet 3. As the edge 2E of the first sheet 2 and the edge 3E of the second sheet 3 approach the head 7, the play of the natural hair 8 between the head 7 and the first sheet 2 and the second sheet 3 is reduced. Thereby, the wig fixture 1 is firmly fixed to the head 7.

[0021] When the prosthetic hair fixing device 1 is positioned along the head 7, the root side of the natural hair 8 is positioned above the hair tip side. Therefore, between the first sheet 2 and the second sheet 3, water and other liquids are more likely to penetrate from the side of the upper edge 2E and edge 3E than from the side of the lower edge 2F and edge 3F. In this prosthetic hair fixing device 1, since the edge 2E of the first sheet 2 and the edge 3E of the second sheet 3 are connected, the penetration of water and other liquids between the first sheet 2 and the second sheet 3 from between the edge 2E and edge 3E is suppressed. As a result, the prosthetic hair fixing device 1 can maintain the adhesive strength of the adhesive over a long period of time.

[0022] Furthermore, in the hair extension device 1, the edge 2E of the first sheet 2 and the edge 3E of the second sheet 3 are the fold line 4F of sheet 4. This hair extension device 1 can be easily manufactured by processing a single sheet 4.

[0023] The hair extension device 1 attached to the head 7 is preferably thin. The thin first sheet 2 and second sheet 3, shown in Figure 1B, with a thickness T, do not impair the appearance of the head 7 to which the hair extension device 1 is attached. The hair extension device 1 is unlikely to cause discomfort when touched to the head 7. Furthermore, the hair extension device 1 is unlikely to cause discomfort even when the head 7 is placed on a pillow while attached. From these viewpoints, the thickness T is preferably 0.29 mm or less, more preferably 0.20 mm or less, and particularly preferably 0.15 mm or less.

[0024] As shown in Figure 1A, a prosthetic hair fixing device 1 with a large opening length HL is easily fixed to the head 7 and less likely to slip. Therefore, the length HL of the opening 5 is preferably 20 mm or more, more preferably 25 mm or more, and particularly preferably 30 mm or more. On the other hand, a prosthetic hair fixing device 1 with a small opening length HL makes it easier to conform the opening 5 to the shape of the head 7. Therefore, the length HL of the opening 5 is preferably 40 mm or less, and more preferably 35 mm or less.

[0025] Furthermore, the hair extension device 1 with a small opening width HW shown in Figure 1A makes it easier to apply adhesive to the natural hair 8 that passes through the opening 5, and also easier to adhere to the first sheet 2 and the second sheet 3. This hair extension device 1 can reduce the number of natural hairs 8 that pass through the opening 5 but are not adhered to the first sheet 2 or the second sheet 3.

[0026] Furthermore, as shown in Figure 3B, when the hair extension device 1 is fitted along the head 7, the hair extension device 1 with a small width HW can shorten the length of the natural hair 8 from the edge of the opening 5 to the head 7 in the first sheet 2 located on the outside. This hair extension device 1 can reduce the slack of the natural hair 8 from the edge of the opening 5 to the head 7.

[0027] Thus, the width HW of the opening 5 is preferably less than 1 mm, and more preferably 0.5 mm or less, from the viewpoint of bonding the natural hair 8 to the first sheet 2 or the second sheet 3 and minimizing the slack of the natural hair 8 between the head 7 and the opening 5. Furthermore, the opening 5 may be formed by cutting a part of the fold 4F of the sheet 4.

[0028] In the hair extension device 1 shown in Figure 1A, where the connection length C1 is large, alignment is easier when bonding the first sheet 2 and the second sheet 3 together. Therefore, the connection length C1 is preferably 2.5 mm or more, more preferably 5.0 mm or more, and particularly preferably 7.5 mm or more. On the other hand, in the hair extension device 1, where the connection length C1 is small, the lengths of the first sheet 2 and the second sheet 3 can be shortened. Therefore, the connection length C1 is preferably 10 mm or less, more preferably 7.5 mm or more, and particularly preferably 5.0 mm or less.

[0029] As shown in Figure 1A, the prosthetic hair fixation device 1 with a large connection length C2 allows for easy alignment when bonding the first sheet 2 and the second sheet 3. On the other hand, the prosthetic hair fixation device 1 with a small connection length C2 allows for shorter lengths of the first sheet 2 and the second sheet 3. Therefore, the preferred range for the connection length C2 is the same as the preferred range for the connection length C1.

[0030] Furthermore, in a prosthetic hair fixation device 1 where the end edge 2E of the first sheet 2 is connected to the end edge 3E of the second sheet 3 at both ends of the first sheet 2, alignment is easily achieved when bonding the first sheet 2 and the second sheet 3 together. Note that the connection between the end edge 2E of the first sheet 2 and the end edge 3E of the second sheet 3 may be made at only one of the ends of the end edge 2E of the first sheet 2.

[0031] Furthermore, in the prosthetic hair fixation device 1, the first sheet 2 and the second sheet 3 may be made of separate sheets. It is sufficient that the edges 2E of the first sheet 2 and the edge 3E of the second sheet 3 are connected when the separate first sheet 2 and second sheet 3 are bonded together. By bonding and connecting the edges 2E of the first sheet 2 and the edge 3E of the second sheet 3, it is possible to suppress the intrusion of water, etc., between the first sheet 2 and the second sheet 3 from between the edges 2E and 3E.

[0032] Furthermore, from the viewpoint of preventing water or other substances from entering between the first sheet 2 and the second sheet 3, it is preferable that the first sheet 2 and the second sheet 3 be bonded and connected from one end of edge 2E and edge 3E to the other end, including the area where the opening 5 between edge 2E and edge 3E is formed. Moreover, from this viewpoint, it is preferable that the entire surface of the back surface 2B of the first sheet 2 and the entire surface of the back surface 3B of the second sheet 3 be bonded together.

[0033] In this hair extension device 1, the back surface 2B of the first sheet 2 and the back surface 3B of the second sheet 3 can be bonded for a long period of time. Furthermore, the hair extension device 1 minimizes the slack of natural hair 8 between the head 7 and the first and second sheets 3. As a result, the hair extension device 1 can be fixed to the head 7 for a long period of time. The hair extension device 1 can be used during bathing and hair washing without removal. It does not need to be attached or removed during daily life. Also, when natural hair 8 grows, the bond between the first and second sheets 3 can be released using a cleaner, and then the first and second sheets 3 can be reattached while closer to the head 7, thereby minimizing the slack of natural hair 8 between the head 7 and the first and second sheets 3. With regular maintenance, the hair extension device 1 can be worn on the head 7 without interfering with daily life.

[0034] Furthermore, in the artificial hair fixing device 1, the first sheet 2 and the second sheet 3 are bonded together with adhesive, but they may also be bonded together with double-sided tape. When bonding the back surface 2B of the first sheet 2 and the back surface 3B of the second sheet 3, the film may be peeled off from the adhesive surfaces of the double-sided tape on the back surfaces 2B and 3B, thereby bonding the first sheet 2 and the second sheet 3 together.

[0035] Furthermore, in the hair extension device 1, natural hair 8 growing from the head 7 is passed through the opening 5, but it is not limited to natural hair 8. Alternatively, artificial hair fixed to the head 7 by means other than the hair extension device 1 may be passed through the opening 5, and the hair extension device 1 may be fixed to the head 7.

[0036] Furthermore, Figures 4A and 4B show other usage states of the hair extension device 1. Here, the configuration and effects that differ from those of the hair extension device 1 in Figures 2A and 2B will be explained, while the explanation of similar configurations and effects will be omitted.

[0037] In Figures 4A and 4B, the human hair 6 is fixed to the hair extension fixture 1 in the opposite direction to that shown in Figures 2A and 2B. As shown in Figure 4B, the human hair 6 is fixed with the roots towards edge 2F and the tips towards edge 2E. The other edge 2F of the first sheet 2 and the other edge 3F of the second sheet 3 are in contact with the head 7.

[0038] In Figure 4A, the double-headed arrow RL represents the length of the area R to which the natural hair 8 is attached on the back surface 2B of the first sheet 2. For example, the length of area R RL is the same as the length L of the opening 5. The double-headed arrow RW represents the width of the area R to which the natural hair 8 is attached on the back surface 2B of the first sheet 2.

[0039] Here, the method for attaching the hair extension device 1 shown in Figures 4A and 4B will be explained. As shown in Figure 4B, the hair extension device 1 is prepared with human hair 6 fixed to the first sheet 2. Adhesive is applied to the area R of the back surface 2B shown in Figure 4A. On the head 7 of the person to whom the hair extension device 1 will be worn, some of the natural hair 8 is separated from the rest of the natural hair 8. The edge 2F of the first sheet 2 is brought closer to the head 7 around the separated portion of natural hair 8. The separated portion of natural hair 8 is bonded to the area R of the back surface 2B of the first sheet 2. The separated portion of natural hair 8 is pulled out through the opening 5. Adhesive is applied to the back surface 2B of the first sheet 2 and the back surface 3B of the second sheet 3. With the edge 2F of the first sheet 2 and the edge 3F of the second sheet 3 in contact with the head 7, the back surface 2B of the first sheet 2 and the back surface 3B of the second sheet 3 are bonded together, sandwiching the portion of natural hair 8. In this way, the hair extension device 1 is put into the state of use shown in Figures 4A and 4B.

[0040] Although not shown in the diagram, the artificial hair fixing device 1 and the human hair 6 are attached to the head 7 together with the natural hair 8. Furthermore, adhesive may be applied to the surface 3A of the second sheet 3, and the surface 3A may be adhered to the head 7.

[0042] The hair extension device 10 comprises a third sheet 13 to which a net 11 is attached on its surface 13A, and a fourth sheet 14 to which the patient's own hair 8 is sandwiched and bonded between the third sheet 13 and its back surface 13B. The device has an opening 15 through which the patient's own hair 8 passes, on a line between one end 13E of the third sheet 13 and one end 14E of the fourth sheet 14. One end 13E of the third sheet 13 and one end 14E of the fourth sheet 14 are connected. Human hair 12 is attached to the surface 13A via the net 11. The hair extension device 10 has the same structure as the hair extension device 1.

[0043] In the wig 9's hair fixing device 1, the edge 2F of the first sheet 2 is located on the root side of the human hair 12, and the edge 2E and opening 5 are located on the tip side of the human hair 12. In the hair fixing device 10, the edge 13F of the third sheet 13 is located on the root side of the human hair 12, and the edge 13E and opening 15 are located on the tip side of the human hair 12. Alternatively, the edge 2E and opening 5 of the first sheet 2 may be located on the root side of the human hair 12, and the edge 2F may be located on the tip side of the human hair 12. Similarly, the edge 13E and opening 15 of the third sheet 13 may be located on the root side of the human hair 12, and the edge 13F may be located on the tip side of the human hair 12.

[0044] In the wig 9, the hair extension fasteners 1 and 10 are positioned separately and each is attached to the head 7, preventing the wig 9 from peeling off the head 7. Furthermore, the wig 7 can be made less likely to shift and can be fixed in place for a long period of time.

[0045] Figure 6 shows a wig 16. This wig 16 comprises a plurality of hair extension fasteners 1, a net 17 to which the plurality of hair extension fasteners 1 are attached, and a plurality of human hair strands 18 fixed to the net 17. The plurality of hair extension fasteners 1 are sewn to the net 17. The plurality of hair extension fasteners 1 are positioned in a line along the edge of the net 17. The plurality of hair extension fasteners 1 may be sewn to the net 17 or glued to it. The net 17 has multiple meshes throughout its entire surface through which the natural hair 8 can be passed.

[0046] In the wig 16 hair fixing device 1, the end edge 2E and opening 5 of the first sheet 2 are located on the root side of the human hair 18, and the end edge 2F is located on the tip side of the human hair 18. However, the end edge 2F of the first sheet 2 may be located on the root side of the human hair 18, and the end edge 2E and opening 5 may be located on the tip side of the human hair 18.

[0047] The wig 16 is fixed to the head 7 by attaching multiple hair extension devices 1 to the head 7. The wig 16 is less likely to shift and can be fixed for a long period of time.
