WIG

Abstract: A wig or hairpiece comprising a wig base (1, 11) formed by a network (2, 12) having such a convexly curved face as is in argreement with the contour of the head of the user, and hair (H) planted all over the surface of the convexly curved face of the network (2, 12), wherein the wig base (1, 11) is made zigzag at its front edge portion (4) which corresponds to the upper forehead of the user's head and wherein the wig base (1, 11) is stitched a little inside its front portion (4) by a filament (5).

Description: BACKGROUND OF THE INVENTION a) Field of the Invention The present invention relates to a wig or hairpiece whose base is formed by a network and, more particularly, it relates to an improvement of wigs or hairpieces, enabling a natural hairline to be simulated at the front of the head of a wearer, a whirlpool of hairs to be formed on the head, that wig base, which is exposed at the hair-parting line, to seem as if it were the natural head skin of the wearer, and the wig itself to be made sufficiently wear-durable. b) Description of the Prior Art Various kinds of wigs or hairpieces whose bases are formed by networks are well known. One of these wig bases is taught, for example, by the wig base manufacturing method disclosed in a Japanese Patent Preliminary Publication No. Sho 61-124615 laid open on June 12, 1986 and filed by the same applicant as that of the present invention. According to this wig base manufacturing method, the wig base is formed by applying a special shaping treatment to its network to insure that the wig can keep such contour and dimension as are in strict agreement with the shape of the head of the wearer or user on which the wig is to be placed. This makes it more difficult that the wig base is deformed, even after it is used for a long time. In the case of this wig base, however, no consideration is paid to making the front edge portion of the wig base, which is located at the front of the head of the user, look natural. In the case of those wigs whose bases are formed by a network, a fringing ribbon or tape is stitched or stuck along the inner face of the peripheral edge of the network so as to reinforce the shape of the network and conform the whole of the wig to the contour of that scalp area of the user which is to be covered. In the wigs of the so-called hard front type, this fringing ribbon or tape is stitched to the inner face of the front edge portion of the wig base which corresponds to the hairline portion on the forehead of the user, so that the front edge portion of the wig can be prevented from floating from the forehead of the user. When this reinforcement technique of stitching or sticking the fringing ribbon or tape to the wig base is applied to the wig base which is made according to the method of the Japanese Patent Preliminary Publication No. Sho 61-124615, the wig thus formed can keep its shape more effectively and enhance its wear-durability. In the case where the wig thus formed lends itself to brush-back hair styles, however, those hairs which have been attached to the outer face of the front edge portion of the wig base are combed rearwardly of the hairline at the front edge portion of the wig base. Therefore, the fringing ribbon or tape which has been stitched or stuck to the inner face of the front edge portion of the wig base is exposed to thereby create a visual indication of the presence of the wig. In order to overcome this problem, a wig or hairpiece of the so-called lace front type is provided by a US Patent No. 4,509,539, for example. In the case of this wig, the whole of wig base is constituted of a network of lace meshes wherein a plurality of filaments which are crossed one another to form meshes are ultrasonically welded at their intersections. Therefore, this network of lace meshes is not fringed at the front edge portion thereof and the wig of this type thus enables its hairline to look as if its hairs were growing directly from the skin of the user's head at his upper forehead area. Even in the case of brush-back hair styles, therefore, the border between the user's forehead and the front edge portion of the wig can certainly provide a natural hairline, but this wig or hairpiece has the following drawbacks. The network of those filaments which form the front edge portion of the wig base is ultrasonically welded at the intersections of the filaments, but as compared with the wigs of the above-described hard front type, it is not fringed at its front edge portion. Its shape-holding capacity becomes lower accordingly, and this wig thus loses and deforms its shape as years go by. Clearance is thus created between the user's forehead and the front edge portion of the wig base, thereby causing this front edge portion to be curled up or bent under itself and sometimes causing the filaments, which form the front edge portion of the wig base, to be made visible because of the front edge portion of the wig base floated from the user's forehead. When this wig is used for a long period, those filaments which form the wig base along the front edge portion thereof are parted from one another at some of their welded intersections and some of those filaments which form the not-reinforced network are broken, thereby making it likely for the network to become loose at the front edge portion of the wig base. The deformation of the wig base and the loosening of the network at the front edge portion thereof are often caused at hair brushing, washing and careless treating times, thereby reducing the wear-durability of the wig. On the other hand, this wig of the lace mesh type is constituted of a network. In the case where a hair-parting line is formed on the wig, therefore, the filaments which form the network are exposed at this hair parting line where the user's own skin should appear, thereby visually indicating the presence of the wig. When a whirlpool of hairs is to be formed on the wig, hair fibers which are planted on the surface of the wig base must have a higher density at an area where the whirlpool of hairs is formed than at the other remaining area. When they are planted, the hair fibers must also be directed in clockwise or anti-clockwise direction to have a flow or whirlpool of hairs. In a case where the whirlpool of hairs is to be formed on the wig which is made by a network according to the US Patent No. 4,509,539, however, the number of hair fibers planted cannot be increased because the meshes of the network are formed rectangular and certain in size. Further, the hair fibers are bound to those filaments which form the rectangular meshes, and they has a pattern of lattice when thus planted, thereby making it difficult to form a pattern of whirlpool. Still further, each of the hair fibers which have been bound to the mesh filaments is shifted from its original position and direction by hair brushing or the like. It is therefore difficult to keep the hair fibers planted under a certain flow of hairs, thereby making it impossible to form the whirlpool of hairs on the wig of this US Patent. Furthermore, in order to make the hairline look natural at the front edge portion of the wig base, it is more preferable that the hair fibers which are to be planted at the front edge portion are bound there with an appropriate space and at random rather than in linear and close alignment. When meshes are rough at the front edge portion of the wig base, however, the hair fibers bound are limited in number and position, thereby making it difficult to provide a random and natural hairline. SUMMARY OF THE INVENTION An object of the present invention is to provide a wig or hairpiece having nothing but the advantages presented by the above-described wigs of the hard and lace front types. Another object of the present invention is to provide a wig or hairpiece wherein the wig base cannot become loose at its front edge portion which corresponds to the upper forehead of a user and wherein those hair fibers which have been planted at the front edge portion of the wig base can create a natural hairline. A further object of the present invention is to provide a wig or hairpiece enabling a whirlpool of hairs to be formed on the wig base and hairs to be appeared as if they were growing directly from the user's own skin, so that a net work which forms the wig base cannot be made visible at the whirlpool of hairs and hair-parting line. A still further object of the present invention is to provide a wig or hairpiece which can keep its shape even after its long use and which is light in weight and has sufficient ventilation. According to the present invention, these and other objects can be achieved by a wig or hairpiece comprising a wig base constituted of a network having a convexly curved face which conforms to the contour of a user's head to be covered, and hair fibers planted on all over the convexly curved face of the wig base, wherein the network of the wig base is formed zigzag at its front edge portion which corresponds to the upper forehead of the user and wherein the front edge portion of the wig base is stitched along and a little inside the front edge thereof by a filament. The network which forms the wig base comprises substantially diamond-shaped meshes formed by ultrasonically welding filaments, preferably resin-coated filaments at their intersections. The wig or hairpiece is preferably cut away at least at an area of its network where a whirlpool of hairs is to be formed, and this cut-away portion is covered by a flesh-colored artificial skin made of a sheet of flexible plastics and same in shape as the cut-away portion. In this case, the artificial skin complementally attached to the cut-away portion is formed zigzag at the front edge portion thereof, as seen at the front edge portion of the network. This can also be said similarly about the front edge portion of the cut-away portion. The cut-away portion may be extended from the whirlpool of hairs and along the hair-parting line, and it may be closed by a flesh-colored artificial skin made of flexible plastics and same in shape as it. In this case, the artificial skin complementally attached to the cut-away portion is formed preferably zigzag at the front edge portion thereof, similarly to the front edge portion of the network. The artificial skin is preferably provided with a plurality of pinholes for ventilation. The network which forms the wig base is stitched zigzag along and a little inside the front edge thereof by a filament, the stitching of said filament zigzagging along or against the zigzag of the front edge portion of the network. The wig or hairpiece comprises a first net occupying hair-parting and forehead areas of the network and a second net occupying the other remaining area of the network. The first net has meshes smaller than those of the second net.For example, the first net has about 28 - 48 meshes per square inch, preferably about 32 - 35 meshes per square inch, while the second net has about 14 - 24 meshes per square inch, preferably about 16 - 20 meshes per square inch. The first and second nets are bonded by resin coating or stitched together at their peripheral edges. According to the present invention, almost all of the wig base is formed by a network and excellent ventilation is thus provided not to make the user's head stuffy. Further, the zigzag front edge of the wig base makes it difficult for other persons to visually notice the front edge portion of the wig base. Still further, the wig base is stitched a little inside the front edge thereof by a filament and thus reinforced, so that the net can be prevented from becoming loose at the front edge portion of the wig base even after the wig is used for a long period, and that the wig base can also be prevented from curling up or deforming its shape at the front edge portion thereof while it is being used. According to one aspect of the present invention, at least an area of the wig base where a whirlpool of hairs is to be formed or this area including the hair-parting portion of the wig base is formed by a flesh-colored artificial skin instead of a network. The whirlpool of hairs can be thus formed by implanted hair fibers. In addition, the arti ficial skin which is exposed at the whirlpool of hairs and along the hair-parting portion can make it more difficult for other persons to visually notice the presence of the wig. Further, according to another aspect of the present invention, the hair-parting portion of the wig base including that area thereof which corresponds to the user's forehead is formed by a first net which has meshes smaller than those of a second net which occupies the other remaining area of the wig base network. The first net having smaller meshes is thus exposed at the front edge portion and along the hair-parting portion of the wig base, thereby leaving the presence of the wig much less noticeable. In addition, the first net can help the wig base keep its shape. In this case, the hair fibers can be randomly attached to the first more-finely-meshed net at the front edge portion of the wig base, thereby creating a natural hairline. Other characteristics and merits of the present invention will become apparent from the following detailed description with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail, referring to some embodiments of the present invention shown in the drawings. Fig. 1 is a view showing the inner face of a wig or hairpiece W which is embodied as a first embodiment of the present invention. The wig W comprises a wig base 1 having a convexly curved face which is in strict agreement with the contour and dimension of the head scalp of a user, and human and/or artificial hairs H attached to the convexly curved face of the wig base 1. The whole of the wig base 1 is formed by a network 2 comprising first and second filaments 2a and 2b, each being colored to look as if it had same color as the head skin of a user, made of nylon and having usually 220 - 330 deniers, wherein the first and second filaments 2a and 2b are plain-woven, alternately crossing each other at intervals, and wherein the first and second filaments 2a and 2b thus woven are ultrasonically welded at their intersections 2d to form rectangular or preferably diamond-shaped net patterns 2c, as shown in Fig. 2. Each of the filaments 2a and 2b which form the network 2 is coated with a polyurethane resin film 3, as shown in Fig. 3, to have a certain strength and enable the wig base 1 to retain its convexly curved face which is in agreement with the scalp of the user's head. The method of forming this network 2 is disclosed by the Japanese Patent Preliminary Publication No. Sho 61-124615 filed by the same applicant as of the present invention. As shown in Fig. 4, hair fibers H are bound to the first and second filaments 2a and 2b at some appropriate positions and welded-intersections 2d of these filaments. The network 2 which forms the wig b ase 1 has a front edge portion 4 which conforms to the position and dimension of the upper forehead of the user's head. As apparent from an enlarged part of the front edge portion 4 of the network 2 shown in Fig. 5, the free end of the front edge portion 4 is formed zigzag, extending right to left on the upper forehead of the user's head, so as to achieve such a camouflaging effect that the front edge portion 4 of the wig base 1 creates a natural hairline looking as if it were a natural border of hairs at the upper forehead of the user's head, and the hair fibers H are bound as near the outer tip of each of the zigzags as possible. Further, the wig base 1 is stitched zigzag a little or about 3 - 15mm, for example, inside the zigzag front edge portion 4 thereof by a nylon filament 5 made of same material and colored in same color as those of the first and second filaments 2a and 2b, said nylon filament 5 zigzagging along or against the zigzags of the front edge portion 4 and extending right to left on the upper forehead of the user's head. When the stitching filament 5 is not zigzag- but line-sewed, it can be easily noticed through clearances between the planted hair fibers. It is therefore preferable that the stitching filament 5 is zigzag-sewed. It is also preferable that the nylon filament which is used as the stitching filament 5 is as fine as possible, having 30 - 60 deniers, more preferably 40 - 50 deniers. When the stitching filament 5 has a value larger than 60 deniers, the area of the front edge portion 4 which is stitched by the filament 5 is deformed to deteriorate the shape-retaining capacity, and the filament 5 contacts the upper forehead of the user's head to make the user feel disagreeable. When the filament is too fine, its strength becomes low to thereby loosen the front edge portion 4 of the network. As shown by a broken line in Fig. 1, a cut-away portion 6 is formed near the backside of the wig base 1 and at an area 6a thereof where a whirlpool of hairs is to be formed, and an artificial skin 7 made of a sheet of plastics and having a shape which conforms to the cut-away portion 6 is fixed to the network 2 to cover the cut-away portion 6. The artificial skin 7 is made of preferably soft, elastic and flexible polyurethane or silicone resin, having a thickness of about 0.1 - 0.6mm, usually about 0.4mm. The artificial skin 7 which has been colored in same color as the head skin of the user is transparent or semi-transparent and its surface is frost-finished. It is provided with a plurality of fine through-holes 8 each having a diameter of about 0.5mm so as to provide excellent ventilation to prevent the scalp area of the user's head, which is covered by it, from feeling stuffy. In the case of this embodiment shown in Fig. 1, the cut-away portion 6 extends from the whirlpool area 6a and along a hair-parting portion 6b and it is zigzagged at its front edge 6c to achieve the camouflaging effect of blurring its portion overlapped with the artificial skin 7. The artificial skin 7 is also zigzagged a the front edge thereof and along the zigzags of the front edge of the network 2 to achieve the same camouflaging effect. The border between the artificial skin and the network can be thus prevented from visually noticing through clearances between the hairs, even when the wig user is seen in front of him. The artificial skin 7 is welded, bonded or stitched to the cut-away portion 6 at their peripheral edge. It is therefore advantageous that the artificial skin 7 is made a little larger than the cut-away portion 6. The circumferential rim of the network 2 which includes right and left side edge and backside edge portions but for the front edge portion 4 is fringed by a coating of polyurethane resin or the like to prevent the filaments, which form the network 2, from becoming loose and reinforce the network 2. This fringed rim 9 is covered by the planted hair fibers and thus left unexposed. As shown by a broken line in Fig. 1, plural b onding strips (four strips in Fig. 1) 10a, 10b, 10c and 10d made of coating of polyurethane resin may be arranged on the inner face of the circumferential rim of the wig base 1. These bonding strips serve as stoppers or stays such as double-bonded tape to fix the wig W to the user's head. It is extremely advantageous to use the stopper disclosed by a Japanese Patent Publication No. Sho 54-16785 filed by the same applicant as of the present invention. A polyurethane resin film may be stitched to some appropriate positions on the inner face of the wig, without forming the bonding strips 10a, 10b, 10c and 10d by coating. A wig manufacturing process of the present invention will be described below. Using a male die which is in strict agreement with the contour and dimension of the scalp of the user's head, the network 2 is made according to the method of the Japanese Patent Preliminary Publication No. Sho 61-124615. The front edge portion 4 of the network 2 is zigzagged right to left by scissors to cover the upper forehead of the user's head and the network 2 is then machine-sewed about 3 - 15mm inside the zigzag front edge portion 4 thereof by a nylon filament. When the nylon filament is not line- but zigzag-sewed along or against the zigzag front edge portion 4 this time, the camouflaging effect is enhanced to leave the filament-stitching portion 5 imperceptible. The sloping side of each of the zigzags formed at the front edge of the network 2 and by the stitching filament 5 may be made about 3 - 13mm long, respectively. Each of the filaments 2a and 2b which form the network 2 is coated by the polyurethane resin film 3, as shown in Fig. 3, to make them strong and prevent them from becoming loose. In addition, they are ultrasonically welded at their intersections 2d by the ultrasonic welder. It is preferable that the stitching nylon filament is also coated by the polyurethane resin film 3 and welded to the network at their intersections to increase the strength of the network. The network 2 is cut away by scissors at the whirlpool-forming area thereof and also at the hair-parting area thereof extending from the whirlpool-forming area to thereby form the cut-away portion 6, whose front edge is cut zigzag this time. The artificial skin 7 same in shape as or preferably a little wider than the cut-away portion 6 is independently made using the above-mentioned male die and bonded or stitched to cover the cut-away portion 6. When coating is applied using polyurethane or silicone resin, the artificial skin 7 is made about 3mm wider than the cut-away portion 6 and coated masking its peripheral rim of about 3mm which is overlapped upon the network 2 to cover the cut-away portion 6. Fringing resin coating is similarly applied to the peripheral rim of the network 2 except the front edge portion thereof and the fixing bond strips 10a, 10b, 10c and 10d such as stopper and double-bonded tape are formed by resin coating at some appropriate positions on the inner face of the network 2 and along the peripheral rim thereof. Instead of the bonding strips, a polyurethane resin film may be stitched to the inner circumferential face of the network 2. Finally, human and/or artificial hairs are implanted on the outer surface of the wig base thus manufactured. It is preferable in this case that the hair fibers H are attached as near the tip of each of the zigzags as possible at the front edge portion 4 of the network 2 to create a natural hair line. Further, as compared with the other remaining area of the network 2, a larger number of the hair fibers H are attached to the artificial skin, which covers the whirlpool-forming area of the network 2, to form the whirlpool directed clockwise or anti-clockwise. After the hair fibers H are thus planted, the artificial skin is punched to form a plurality of fine through-holes each having a diameter of about 0.5mm, thereby enabling the first example of the wig to be finished. Fig. 6 shows a second embodiment of the present invention, which is a variation of the artificial skin fixed to the cut-away portion of the network. Generally, the shape of a human head is a semi-sphere when curved lines are drawn in all directions, centering the parietal point of the head, and the portion of the head which extends from the parietal area to the forehead can be most visually noticed by other persons. When the network is formed by an artificial skin, colored in same color as the head skin of the user, at that portion of the head where the head skin can be easily noticed through clearances between the hair fibers, therefore, the presence of the wig can be made much less noticeable. An artificial skin 7′ is therefore extended from the whirlpool-forming area to the neighborhood of the forehead along the hair-parting line. When a cut-away portion 6′ is zigzagged, as seen in Fig. 1, at least at the front edge 6′c thereof which faces the forehead of the user's head and the artificial skin 7′ substantially same in shape as the cut-away portion 6′ is fixed to the cut-away portion 6′ in this case, the border between the network 2 and the artificial skin 7′ can be blurred to enhance the camouflaging effect. In the case of the two embodiments shown in Figs. 1 and 6, a part of the network is cut away and a piece of artificial skin is attached to this cut-away portion of the network. However, the piece of artificial skin which is made independently of the network may be attached to that area of the network where the whirlpool and/or hair-parting portion are to be formed, without cutting away this area of the network. Alternatively, resin coating may be applied directly onto this area of the network where the whirlpool and/or hair-parting portion are to be formed. Same effects as those of the first and second embodiments can be attained in any cases. Fig. 7 shows the inner face of a wig W which is embodied as a third example of the present invention. The whole of this wig base 11 is formed by a network 12 comprising a first net 12a which occupies the hair-parting portion and forehead area of the user's head, and a second net 12b which occupied the other remaining area thereof. Filaments which form the first and second nets 12a and 12b are resin-coated at the circumferential surface thereof and ultrasonically welded at their intersections, as seen in the first embodiment of the present invention. As exaggeratedly shown in Fig. 7, the first net 12a which occupies the hair-parting portion and forehead area has meshes smaller than those of the second net 12b which occupies the other remaining area including the side area opposed to the hair-parting portion, the parietal area and the back area of the user's head. Generally, the net which forms the wig base has comparatively rough meshes or about 14 - 24 meshes per square inch and this roughly-meshed net which is conventionally available can be used as the second net 12b. However, the hair-parting portion and forehead area of the user's head can be most easily noticed by other persons and when the roughly-meshed net is used to cover the hair-parting portion and forehead area, therefore, the number of hair fibers which are bound to net filaments is limited and the wig base net is thus made more noticeable through clearances between the hair fibers. As a result of various studies on this point, it has been found that when the first net 12a has about 28 - 48, preferably about 32 - 35 meshes per square inch, the above problem can be solved because a sufficient number of hair fibers can be planted on the net. The first net 12a has the front edge portion 4 which conforms to the position and dimension of the upper forehead of the user's head. This front edge portion 4 is zigzagged at its free end and stitched zigzag a little inside it by a filament 5, said stitching filament zigzagging along or against its zigzag free end. Numeral 13 represents a connected portion b etween the first and second nets 12a and 12b, wherein the first and second nets 12a and 12b are placed one upon the other at their opposing rims and connected each other by resin coating. They may be stitched or bonded together at their overlapped portions instead of using resin coating, but it is more preferable from the viewpoint of strength and shape-retaining capacity that they are machine-sewed and then connected by resin coating. It should be understood that the present invention is not limited to the above-described embodiments, but that various changes and modifications can be made without departing from the spirit and scope of the present invention. For example, it may be optionally done by those skilled in the art that the wig base shown in Fig. 7 is cut away at its portion on which a whirlpool of hairs is formed and that an artificial skin is attached to this cut-away portion. Further, the present invention can be applied to those wig bases which are formed by a woven or non-woven net, as well as the wig base disclosed by the Japanese Patent Preliminary Publication No. Sho 61-124615 filed by the same applicant as of the present invention. The present invention can be therefore applied to the wig base of the US Patent No. 3,905,378, for example, which is formed by a non-woven nylon net.
