Sole structure and method of making the same

Abstract

A sole structure includes a soft body, a hard inner layer member, and a plurality of soft engaging members; wherein the body is made of soft-fiber composite materials without adding thermoset epoxy resin (such as carbon fiber/glass fiber) and formed in a laminate sole shape with a peripheral member, on a bottom surface of the body are formed a plurality of holes; the hard inner layer member is made of engineering plastics and fixed to the bottom surface of the body and includes a number of apertures in response to the holes; the soft engaging members are injection molded from soft composite materials (such as TPU, TPR, etc.) and integrally coupled with the hard inner layer member on the body, such that the soft body, the hard inner layer member, and the soft engaging members are integrally coupled together to form the sole structure.

1 . A sole structure comprising:
 a soft body, a hard inner layer member, and a plurality of soft engaging members; wherein   the body is made of soft-fiber composite materials without adding thermoset epoxy resin and formed in a laminate sole shape with a peripheral member, on a bottom surface of the body are formed a plurality of holes;   the hard inner layer member is made of engineering plastics and fixed to the bottom surface of the body and includes a number of apertures in response to the holes;   the soft engaging members are injection molded from soft composite materials and integrally coupled with the hard inner layer member on the body.   
     
     
         2 . The sole structure as claimed in  claim 1 , wherein the soft-fiber composite materials are selected from carbon fiber and glass fabric 
     
     
         3 . The sole structure as claimed in  claim 1 , wherein the composite materials made into the soft engaging member are selected from TPU and TPR. 
     
     
         4 . The sole structure as claimed in  claim 1 , wherein on connecting portions of the body and the engaging members are arranged a plurality of apertures. 
     
     
         5 . The sole structure as claimed in  claim 1 , wherein the engaging members are fixed on front and rear portions of the bottom surface of the body. 
     
     
         6 . The sole structure as claimed in  claim 1 , wherein the engaging members are fixed on front and rear portions of the bottom surface of the body. 
     
     
         7 . A method of making a sole structure comprising:
 a. making soft-fiber composite materials into a laminate body with a peripheral member and arranging a plurality of holes and openings on a bottom surface of a sole structure;   b. making the engaging members from soft composite materials;   c. putting the body and the engaging members into the mold;   d. injection molding a hard inner layer member which is made of engineering plastics from the mold to an inner end surface of the body and then injection molding the openings and the engaging members together to the body, thereby forming the sole structure.   
     
     
         8 . A method of making a sole structure comprising:
 a. forming soft-fiber composite materials to a laminate body with a peripheral member and arranging a plurality of holes on a bottom surface of a sole structure;   b. putting the body into a mold;   c. injecting a plurality of engaging members from the mold to an outer end surface of the body so as to integrally form the engaging members and the body.   d. putting the integrally formed body and engaging members into another mold;   e. injecting an inner layer member from the mold to an inner end surface of the body so that the inner layer member is integrally formed with the body, thus forming a sole structure.
