Shoe having peeling prevention structure of roll-up portion

Abstract

A shoe comprises: an upper 7 wrapping an instep; an outsole 3 contact with a floor or a road; a front roll-up portion 32 formed as the outsole 3 is rolled up upward along a front end portion 71 of the upper 7 and fixed to the upper 7 ; through hole means running through the front end portion 71 and the front roll-up portion 32 ; and a clamper 1 running through the through hole means to clamp together the upper 7 and the outsole 3 and keep them clamped therein, thus strengthening a fixing strength between the upper 7 and the outsole 3 , wherein the clamper 1 is made of a resin and includes: first flange means engaging with the front roll-up portion 32 on a front surface 31 of the front roll-up portion 32 ; second flange means engaging with the upper 7 on an inner surface of the front end portion of the upper 7 ; and pipe means connecting the first and second flange means and running through the through hole means for ventilation between an inside and an outside of the shoe.

1 . A shoe in which an outsole made of a foamed resin and/or a rubber is rolled up along an upper, comprising:
 an upper for wrapping around an instep;   an outsole to be in contact with a floor surface or a road surface;   a front roll-up portion formed as the outsole is rolled up in an upward direction along a front end portion of the upper and fixed to the upper;   through hole means running through the front end portion of the upper and the front roll-up portion; and   a clamper running through the through hole means to clamp together the upper and the outsole and keep them clamped therein, thus strengthening a fixing strength between the upper and the outsole, wherein the clamper is made of a resin and comprises:   first flange means engaging with the front roll-up portion on a front surface of the front roll-up portion;   second flange means engaging with the upper on an inner surface of the front end portion of the upper; and   pipe means connecting between the first flange means and the second flange means and running through the through hole means for ventilation between an inside and an outside of the shoe.   
     
     
         2 . A shoe according to  claim 1 , wherein the front roll-up portion includes a concave portion concaved in a rear direction, and the first flange means fits in the concave portion. 
     
     
         3 . A shoe according to  claim 2 , wherein the front roll-up portion includes an exposed surface that the first flange means avoids covering and that is exposed in a front direction, and a surface of the first flange means is generally flush with the exposed surface of the front roll-up portion or protrudes in the front direction relative to the exposed surface of the front roll-up portion. 
     
     
         4 . A shoe according to  claim 1 , wherein the first flange means is formed by a strip-shaped first member extending in a width direction of the shoe. 
     
     
         5 . A shoe according to  claim 4 , wherein the front roll-up portion is exposed around an upper side, a lower side, a medial side and a lateral side of the first member. 
     
     
         6 . A shoe according to  claim 4 , further comprising one fitting hole or a plurality of fitting holes running through the strip-shaped first member, wherein one second member or a plurality of second members that are formed so that the second flange means and the pipe means are integrated with each other fit in the fitting hole or the fitting holes. 
     
     
         7 . A shoe according to  claim 6 , wherein there are a plurality of fitting holes and a plurality of second members. 
     
     
         8 . A shoe according to  claim 7 , wherein the fitting hole is provided at each of two end portions of the first member in the width direction, and the second members each fit in one of the fitting holes. 
     
     
         9 . A shoe according to  claim 1 , wherein the clamper further comprises:
 a first member forming the first flange means and including a fitting hole running through the first flange means; and   a second member in which the second flange means and the pipe means are integrated with each other, wherein:   the pipe means of the second member runs through the fitting hole of the first member; and   the clamper clamps together the front roll-up portion and the front end portion of the upper, with an engagement portion formed in the pipe means engaging with a periphery of the fitting hole of the first member.   
     
     
         10 . A shoe according to  claim 1 , wherein a JIS K 6253A hardness of a member of the first flange means of the clamper is greater than a JIS K 6253A hardness of the front roll-up portion. 
     
     
         11 . A shoe according to  claim 1 , wherein the first flange means includes a strip-shaped first flange portion extending in a width direction of the shoe or a plurality of first flange portions spaced apart from each other in the width direction of the shoe;
 the second flange means includes a strip-shaped second flange portion extending in the width direction of the shoe or a plurality of second flange portions spaced apart from each other in the width direction of the shoe; and   the pipe means includes a strip-shaped pipe portion whose transverse cross section extends in the width direction of the shoe or a plurality of pipe portions spaced apart from each other in the width direction of the shoe.   
     
     
         12 . A shoe according to  claim 1 , wherein the pipe means is formed by a pipe portion having a ventilation hole, and a position of a lower end of the ventilation hole is placed at a same level as an upper surface of an innersole placed on an upper side of the outsole or is placed at a vicinity that is upper level than the upper surface. 
     
     
         13 . A shoe according to  claim 12 , wherein the second flange means includes a second flange portion protruding in a radial direction of the pipe portion, wherein a lower end of the second flange portion is placed at a lower level than the upper surface of the innersole, and a lower end portion of the second flange portion is sandwiched between the upper and a front end of the innersole.
