Wig base with adjusting mechanism in trifurcate shape

Abstract

In a wig base comprising an occipital base A, a parietal base B, a side base C and a nape portion base D, one end of a first adjusting belt 10 which can expand and contract is fixed to the side base C, one end of a second adjusting belt 20 which can expand and contract is fixed to the parietal base B, and one end of a third adjusting belt 30 which can expand and contract is fixed to the nape portion base D respectively. Other ends of first to third adjusting belts are coupled at one position in a trifurcate shape, thereby forming an adjusting mechanism. The wig base having this configuration can be adjusted finely so as to make the wig base fit a wearer's head with using a pull from three directions by the three adjusting belts.

1 . A wig base, wherein:
 one end of a first adjusting belt which can expand and contract, one end of a second adjusting belt which can expand and contract and one end of a third adjusting belt which can expand and contract are fixed to arbitrary three positions on an inner surface of the wig base respectively, and other ends of the first to third adjusting belts are coupled at one position in a trifurcate shape.   
     
     
         2 . The wig base according to  claim 1 , wherein:
 said three positions includes two positions located at an interval along a circumferential direction of a wearer's head, and remaining one position located at an inner location of the wig base.

 an occipital base which covers the occipital region of a wearer's head,   a parietal base connected to the occipital base, which covers an area from the parietal region to the sinciput region of the wearer's head,   a side base connected to the parietal base, which covers the temporal region of the wearer's head,   a nape portion base connected to the occipital base, which covers a neckline of the wearer,   wherein:   said one end of the first adjusting belt is fixed to the side base, said one end of the second adjusting belt is fixed to the parietal base, and said one end of the third adjusting belt is fixed to the nape portion base respectively.   
     
     
         4 . The wig base according to  claim 1 , wherein:
 at least one of the first to third adjusting belts is configured such that a reference length thereof to which no external force is applied can be adjusted.   
     
     
         5 . The wig base according to  claim 1 , wherein:
 loop portions are formed at said other ends of the first to thirds adjusting belt respectively, and said other ends are coupled at one position in the trifurcate shape by inserting a ring member into the loop portions.   
     
     
         6 . The wig base according to  claim 3 , wherein:
 in said nape portion base, a plurality of belt end connecting portions are provided along a circumferential direction of the wig base, and   said one end of the third adjusting belt is position-changeably fixed to the nape portion base by coupling a connecting portion provided at said one end of the third adjusting belt to any one of the belt end connecting portions.   
     
     
         7 . The wig base according to  claim 3 , wherein:
 at least one of said first and third adjusting belts is engaged with the occipital base by flexible member.
