Fastener

Abstract

A fastener including a reversing member (4) having a long side portion (4a,4b) curved so that a central region in a longitudinal direction protrudes; and a plurality of comb teeth (10,12) connected at one end to the long side portion, another end of the comb teeth being a free end. The comb teeth extend in a direction intersecting the longitudinal direction of the long side portion, and the comb teeth are arranged at predetermined intervals along the longitudinal direction of the long side portion. The comb teeth include a first and second comb teeth at least having different lengths from the one end to the other end, and the first and second comb teeth are disposed adjacent to each other in the longitudinal direction of the long side portion, and extend side by side from the one end to the other end.

1 . A fastener comprising:
 a reversing member having a long side portion curved so that a central region in a longitudinal direction protrudes, the reversing member made of an elastic material; and   a plurality of comb teeth, each of the plurality of comb teeth connected at one end to the long side portion, another end of each of the plurality of comb teeth being a free end, the plurality of comb teeth extending in a direction intersecting the longitudinal direction of the long side portion, the plurality of comb teeth arranged at predetermined intervals along the longitudinal direction of the long side portion,   wherein the plurality of comb teeth include a first comb tooth and a second comb tooth at least having different lengths from the one end to the other end, and the first comb tooth and the second comb tooth are disposed adjacent to each other in the longitudinal direction of the long side portion,   wherein the first comb tooth and the second comb tooth extend side by side from the one end to the other end,   wherein the plurality of comb teeth are changed to a state of being in proximity to and a state of being apart from the reversing member by reversing of the reversing member, and   wherein at a time of use, the first comb tooth and the second comb tooth sandwich hair of a user between the first comb tooth and second comb tooth, and the reversing member in proximity.   
     
     
         2 . The fastener according to  claim 1 , wherein in the longitudinal direction of the long side portion, a first comb teeth region including the one first comb tooth or a plurality of the first comb tooth arranged adjacent to each other and a second comb teeth region including the one second comb tooth or a plurality of the second comb tooth arranged adjacent to each other are arranged adjacent to each other. 
     
     
         3 . The fastener according to  claim 2 , further comprising an arrangement pattern in which the first comb teeth region and the second comb teeth region are alternately arranged in the longitudinal direction of the long side portion. 
     
     
         4 . The fastener according to  claim 1 , wherein the first comb tooth and the second comb tooth are arranged symmetrically with respect to a central portion in the longitudinal direction of the long side portion. 
     
     
         5 . The fastener according to  claim 1 , wherein the reversing member has a substantially quadrilateral planar shape including the long side portion, another long side portion facing the long side portion and curved so that a central region in a longitudinal direction protrudes, and two facing short side portions. 
     
     
         6 . The fastener according to  claim 5 , further comprising a head portion at the free end of each of the comb teeth,
 wherein the head portion is positioned outside the substantially quadrilateral planar shape.   
     
     
         7 . The fastener according to  claim 5 , wherein the other long side portion is provided with a friction member. 
     
     
         8 . The fastener according to  claim 6 , wherein the other long side portion is provided with a friction member.
