Non-sewing material for a footwear upper, footwear upper and footwear using the same

Abstract

A material for a footwear upper, includes a first side corresponding to an inner foot top and an inner side of a foot, a second side corresponding to an outer foot top and an outer side of the foot and extending outwards from an end of the first side to face the first side, a first wing portion extending outwards from the first side in a wing shape, and a second wing portion extending outwards from the second side in the wing shape. The first side and the second side, the first side and the first wing portion, and the second side and the second wing portion are integrated with each other, respectively so that a loss of the material may be reduced and manufacturing efficiency may be improved.

         3 . The material as set forth in  claim 1 , wherein each of the first and second sides comprises an anterior region, a middle region and a heel region which are integrated with each other,
 at a position around a first extrapolated line where the anterior region meets the middle region, a sum of a width of the first side and a width of the first wing portion is equal to a sum of a width of the second side and a width of the second wing portion.   
     
     
         4 . The material as set forth in  claim 3 , wherein, at a position around a second extrapolated line where the middle region meets the heel region, the sum of the width of the first side and the width of the first wing portion is equal to the sum of the width of the second side and the width of the second wing portion. 
     
     
         5 . The material as set forth in  claim 3 , wherein, at the position around the first extrapolated line, the first side is larger in width than the second side, and the first wing portion is smaller in width than the second wing portion. 
     
     
         6 . The material as set forth in  claim 4 , wherein, at the position around the second extrapolated line, the first side is equal in width to the second side, and the first wing portion is equal in width to the second wing portion. 
     
     
         7 . The material as set forth in  claim 1 , wherein the second side extends from a front end or a rear end of the first side. 
     
     
         8 . The material as set forth in  claim 1 , wherein a leading end of the first wing portion is located behind a leading end of the first side, and a leading end of the second wing portion is located behind a leading end of the second side. 
     
     
         9 . The material as set forth in  claim 1 , wherein at a front portion, the first side and the first wing portion, and the second side and the second wing portion are branched, respectively, from each other in an approximately V shape;
 at a rear portion, the first side and the first wing portion, and the second side and the second wing portion are branched, respectively, from each other in an approximately Λ shape; and   at the front portion, a point where the first side and the first wing portion are branched from each other is located in front of a point where the second side and the second wing portion are branched from each other.   
     
     
         10 . The material as set forth in  claim 1 , wherein the material for the footwear upper is non-sewing material. 
     
     
         11 . The material as set forth in  claim 1 , wherein the material is made of textile woven by weft and warp. 
     
     
         12 . The material as set forth in  claim 11 , further comprising:
 an air ventilating portion formed on a predetermined portion of at least one of the first side and the second side;   wherein the air ventilating portion is made by simultaneously weaving upper and lower plates that are looser than a peripheral portion and are vertically separated from each other, and a total number of strands of the weft and warp forming the upper and lower plates is equal to a total number of strands of weft and warp forming the peripheral portion of the air ventilating portion.   
     
     
         13 . The material as set forth in  claim 12 , wherein the upper plate is formed of transparent warp and weft, a colored logo portion is formed on at least portion of the lower plate, and at least one of weft and warp forming the logo portion comprises colored fiber. 
     
     
         14 . A footwear upper manufactured using a material for the footwear upper described in  claim 1 . 
     
     
         15 . A footwear upper, comprising:
 a first side corresponding to an inner foot top and an inner side of a foot;   a second side corresponding to an outer foot top and an outer side of the foot, and extending from an end of the first side to define an opening in footwear in cooperation with the first side; and   a bottom surface extending from the first side and the second side, the bottom surface comprising:
 a first wing portion extending outwards from the first side in a wing shape; and 
 a second wing portion extending outwards from the second side in a wing shape. 
   
     
     
         16 . The footwear upper as set forth in  claim 15 , wherein at a front portion, the first side and the first wing portion, and the second side and the second wing portion are branched, respectively, from each other in an approximately V shape;
