Shoes for competitions

Abstract

The shoe for bicycle competition, with a first member having a convex portion projecting on the bottom with the mounting surface to which a cleat is mounted for position adjustment, covering the heel, the side, and the sole of the feet integrally, the cleat for fixing to a bicycle pedal detachable, and the second member covering the sole to close the opening located on the opposite side of the convex portion. The first member forms an undercut shape with its lateral width narrower upward for the heel of the foot only to move forward, and the third member and the first member share the overlapping portion at least on the side surface of the foot, and by tightening the third member, be integrated by deformation and friction to form a monocoque structure.

What is claimed is: 
     
         1 . A competition shoes wherein on the bottom side, the fixing member for fixing to a fixed object, or blade for skating is detachable,
 having the first member covers integrally foot heel, foot side, and the soles of the foot, having a convex portion projecting to the bottom side,   having the second member covering the sole of the foot, wherein to close the opening located on the opposite side of the convex portion of said first member attached to said first member,   said convex portion has a mounting surface for said fixing member or said blade for the skate, to be mounted for position adjustment.   
     
     
         2 . The competition shoe according to said  claim 1 , wherein said first member is made of the high strength material. 
     
     
         3 . The competition shoe according to said  claim 1 , wherein said convex portion has said mounting surface,
 wherein said cleat is attached adjustably position and angle on the surface,   said fixing member is a cleat for connecting said first member to a bicycle pedal, said the fixed object is said pedal.   
     
     
         4 . The competition shoe according to said  claim 1 , wherein the surface in contact with the foot of said first member and said the second member is created based on the 3-dimensional measurement data of the shape of the individual foot. 
     
     
         5 . The competition shoe according to  claim 1 , wherein the portion of the said first member that covers said side of the foot forms an undercut shape that the lateral width is narrower toward upward from said heel of the foot,
 has a degree of rigidity that heel of the foot can only move forward and not upward in the said first member.   
     
     
         6 . The competition shoe according said  claim 5 , wherein
 said third member covers foot toes, the side of the foot and the instep of the foot, which can move upward and forward direction away from said first member, with a surface in contact with the foot is created based on the 3-dimensional measurement data of the shape of the individual foot and,   the fourth member mounted on the outside of said third member, having a fastening part for clamping and fixing said third member to the said first member, and   said third member and the said first member have a portion which overlaps at least the side surface of the feet, said the third member deformed at tightening, integrated by friction, form a stressed-skin structure.   
     
     
         7 . The competition shoe according to said  claim 6 , wherein the said first member and said third member, are made of a material comprising a high strength fiber and a thermosetting resin. 
     
     
         8 . The competition shoe according to  claim 6 , wherein said first member, and said third member is made of a material comprising fibers and a thermosetting resin having a high strength,
 the dimension in said width and height direction of said foot which contact with the foot of said first member is smaller than said measured data of the shape of the foot of the person,   the size of the toe covering portion of the foot of said third member is greater than, said measurement data of the shape of the foot of the person.   
     
     
         9 . The competition shoe according to  claim 1 , wherein said second member is a plate-like member of a material containing high-strength fibers and a thermosetting resin, an internally hollow cavity member, or a block-like member having a honeycomb or foam structure. 
     
     
         10 . The competition shoe according to  claim 6 , wherein said third member uses a prepreg with parallel aligned extended high-strength fibers, impregnated with a thermosetting resin, then make the tape width 10 mm to 30 mm, and laid up without slack or gap on the mold which was made in advance, side by side, overlapping 3 from 6 directions, with structure having the edge portion of said third member overlapped by said tape parallel to the edge. 
     
     
         11 . The competition shoe according to said  claim 1 , wherein said first member uses a prepreg with parallel aligned extended high-strength fibers, impregnated with a thermosetting resin, then make the tape width 10 mm to 30 mm, and laid up without slack or gap on the mold which was made in advance, side by side, overlapping 3 from 6 directions, with structure having the edge portion of said first member overlapped by said tape parallel to the edge.
