Title: Wigs having length adjusting parts

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a wig to which length adjusting parts are attached, and more particularly, to a wig including a plurality of adjusters or adjusting bands capable of adjusting the length of the wig, which are attached to a back portion of the wig. 
     Generally, there are wigs for totally or partly covering the head or a wig for a bald head. A wig is composed of a wig base having an outwardly curved surface arranged in a shape of wearer&#39;s head and a plurality of hairs affixed to the wig base. The wig base is generally made by nylon yarn and polyester yarn, or is manufactured in the fashion of a net or a network structure made by polyurethane yarn and polycarbonate yarn, etc, or is made with an artificial skin formed by soft synthetic resins such as polyurethane, polycarbonate, etc. There have been used a natural hair, an artificial hair or a mixed hair as wig hair. On the wig base made in the fashion of a net or a network structure, a plurality of hairs made of natural hairs and/or artificial hairs are tied to from a wig. The hairs are fixed on the wig base so that a pair of hairs are protruded above the surface of the wig base. The wig base made by the soft artificial skin has a similar structure to that of the wig base made in the shape of the net or network structure. 
     In case where hairs are fixed on or attached to the net-shaped wig base, an attachment direction or orientation of the hairs is variously selected, and a variety of knots in hairs are provided to prevent the knots from being loose. 
     FIG. 1 is a perspective view showing a conventional wig in which a plurality of hairs are affixed to a net-shaped wig base. As shown in FIG. 1, a conventional wig  10  includes a wig base  11  having a curved surface of an outwardly protruded shape, a plurality of hairs  13  attached to the wig base  11 , an ear support  15  attached to the bottom of a side portion of the wig base  11 , and a back end adjusting part  17  attached to the bottom of a back portion of the wig base  11 . A wearer of the wig properly selects the wig according to his/her tastes in hair colors and the size of his/her head. After wearing the wig, the wearer tightens the wig to fit closely around his/her head and not to be easily uncovered or moved. 
     However, since the back end adjusting part  17  is commonly formed with a Velcro fastener, only a lower portion of the wear&#39;s wig is adjusted to fit to his/her head. Therefore, when having the projected forehead or a slightly abnormal shape of the head, the user should wear the wig hair even though such an arrangement causes any inconvenience, because the length of the front and back of the wig cannot be adjusted. 
     Also, the wig&#39;s wearer adjusts only the back end adjusting part  17  so as to suit the wig to his/her head. Therefore, after wearing the wig by adjusting the back end adjusting part  17 , the wearer should continuously wear the wig even if he/she feels any difficulty due to non-elasticity in a weared condition. 
     SUMMARY OF THE INVENTION 
     In order to solve the problems, an object of the present invention is to provide a wig having length adjusting parts, capable of adjusting the length of the wig according to shapes of wearer&#39;s head and increasing a wearing effect of the wig. 
     To accomplish the above object of the present invention, there is provided a wig including a wig base made by an artificial skin and/or a net having an outwardly curved surface, and a plurality of hairs outwardly sewn on the curved surface of the wig base, comprising: 
     monotapes, affixed to a front portion of the wig base; and a plurality of length adjusting parts, disposed at a back portion of the wig base, for adjusting the length of the front and back of the weared wig. 
     It is preferable that the net forming the wig base is made by filament yarn coated with colors similar to the color of the skin of a wearer&#39;s head. Also, the length adjusting parts are adjusting bands or adjusters. 
     To achieve the above object of the present invention, there is provided a wig including a wig base made by an artificial skin and/or a net having an outwardly curved surface, and a plurality of hairs outwardly sewn on the curved surface of the wig base, comprising: 
     monotapes, affixed to a front portion of the wig base; and an elastic band, attached to the side of the wig base. 
     A plurality of length adjusting parts which can adjust the length of the front and back of the weared wig are further disposed at the back of the wig base. 
     It is preferable that the elastic band which is disposed at the side of the wig base is a wool-made band formed between the front portion and an ear support, and that the net forming the wig base is made by filament yarn coated with colors similar to the color of the skin of a wearer&#39;s head. 
     Also, in case that the wig base is manufactured with an artificial skin, it is preferable that the skin is made by using one of a transparent resin or a semi-transparent resin colored by one of the color of the skin or milk-white color.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Preferred embodiments of the present invention will be described below in more detail with reference to the accompanying drawings. 
     FIG. 2 is a schematically perspective view showing mainly a front portion of the wig according to one embodiment of the present invention. As shown in FIG. 2, the wig is composed of a wig base  100  having an outwardly curved surface and a plurality of hairs  200  adhered to the curved surface of the wig base  100 . Materials constituting the wig base  100  are mainly classified into two parts. First, a front portion directly contacting the forehead or skin of a wearer when wearing the wig, is formed with monotapes  111  having a loose texture. That is, the monotapes  111  are affixed at a constant interval in a vertical direction centering the upper portion of the wig base  100 , and also attached to the lower portion thereof in order to finish a lower end of the wig base  100 . To a back portion  120  at which the back of the wearer&#39;s head is placed, bands  121  being a material of the conventional wig base are affixed approximately across the affixation direction of the monotapes  111  of the front portion  110 . An adhesive member such as an adhesive sheet is attached to a portion where the front portion  110  and the back portion  120  are across each other, in order to connect the front portion  110  and the back porting  120 . Thus, such a treatment can prevent any skin troubles to be caused when a synthetic fiber of the wig&#39;s material contacts the human skin. 
     Also, to further increase a natural viewing effect when wearing the wig, it is preferable to manufacture the wig base  100  by filament yarn coated with colors similar to the skin color of the wearer&#39;s head. Additionally, when the wig base  100  is formed with an artificial skin, it is preferable to manufacture the skin with one of a transparent resin or a semi-transparent resin colored with one of a color of the skin or a milk-white color. 
     To the back portion  120  of the wig base  100 , a plurality of length adjusting parts  122  capable of adjusting the length of the front and back of the wig according to the shape of the wearer&#39;s head are attached, which can be seen in FIG. 3 mainly illustrating the back portion of the wig according to the present invention. 
     In FIG. 3, the length adjusting parts  122  are affixed to the lower portions of the bands  121  constituted in the back portion  120  of the wig base  100 . The length adjusting parts  122  include adjusting bands  122   a  of which one end is attached to the lower portion of the band  121 , and pieces  122   b  of a link shape having a function of adjusting the length of the band  122  by connecting one end of the adjusting band  122   a  with the other end thereof which is placed at a further lower portion of the adjusting band  122   a . This embodiment describes the adjusting band  122  as an example of the length adjusting part, but any part having a length adjusting function such as an adjuster can be used as the length adjusting part  122 , with attachment to the adjusting band. 
     Another embodiment of the present invention can constitute the side of the wig base  100  with an elastic band  150 . FIG. 4 is an enlarged sectional view showing a portion “A” of FIG. 2, which in detail shows the elastic band  150 . That is, a portion between the front portion  110  and an ear support  140  of the wig base  100  which is positioned around the wearer&#39; 3  s ear when wearing the wig, is made by an elastic material, and thus it is prevented that the lower portion of the wig base  100  presses around the ear during wearing. A wool-made band is preferred as the elastic band  150 , but any materials having elasticity can be used. 
     In this embodiment, a plurality of length adjusting parts  122  can be additionally attached to the back portion  120  of the wig base  100  as described in the above embodiment. 
     As described above, the present invention provides the wig of which the length can be freely adjusted by a wearer when wearing the wig, and which can solve any difficulty due to the pressure that the wearer feels during wearing the conventional wig. Also, the present invention provides an effect that the wig&#39;s hair looks like natural human hair by coloring materials of a wig base with colors similar to the color of the head skin. 
     While only certain embodiments of the invention have been specifically described herein, it will be apparent that numerous modifications may be made thereto without departing from the spirit and scope of the invention.
