Healthcare Footwear Article with Silicon Rubber Sole Body and Its Manufacturing Method

Abstract

A healthcare footwear article includes an upper shoe body defining an attachment surface, a healthcare sole member and a midsole member. The healthcare sole member is provided underneath the upper shoe body, and has a bottom outsole portion, an upper insole portion, and a connecting surface, wherein the healthcare sole member is configured from silicon rubber material. The midsole member is provided on the connecting surface of the healthcare sole member, wherein the attachment surface is securely attached on the connecting surface and the midsole member for securely connecting the upper shoe body to the healthcare sole member.

What is claimed is: 
     
         1 . A healthcare footwear article, comprising:
 an upper shoe body defining a receiving cavity and having an attachment surface;   a healthcare sole member which is provided underneath said upper shoe body, and has a bottom outsole portion, an upper insole portion, and a connecting surface, wherein said healthcare sole member is configured from silicon rubber material; and   a midsole member provided on said connecting surface of said healthcare sole member, wherein said attachment surface is securely attached on said connecting surface and said midsole member for securely connecting said upper shoe body to said healthcare sole member.   
     
     
         2 . The healthcare footwear article, as recited in  claim 1 , wherein said upper shoe body is configured from a material other than silicon rubber. 
     
     
         3 . The healthcare footwear article, as recited in  claim 2 , wherein said healthcare sole member has a wearing surface, while said connecting surface of said healthcare sole member is circumferentially and upwardly extended from a side edge portion of said wearing surface, and is arranged to overlappedly attach to said attachment surface of said upper shoe body while said midsole member is sandwiched between said connecting surface and said attachment surface. 
     
     
         4 . The healthcare footwear article, as recited in  claim 3 , wherein said midsole member is configured from fabric materials. 
     
     
         5 . The healthcare footwear article, as recited in  claim 4 , wherein said bottom outsole portion of said healthcare sole member has a bottom surface adapted to contact with an external surface, wherein said upper insole portion is integrally and upwardly extended from said bottom outsole portion. 
     
     
         6 . The healthcare footwear article, as recited in  claim 5 , wherein said upper shoe body, said healthcare sole member and said midsole member are attached together at said connecting surface and said attachment surface by a predetermined adhesive agent. 
     
     
         7 . The healthcare footwear article, as recited in  claim 6 , further comprising at least one reinforcing fiber connecting said upper shoe body and said healthcare sole member, wherein said reinforcing fiber is circumferentially stitched along said attachment surface and said connecting surface so as to reinforce a connection between said attachment surface and said connecting surface. 
     
     
         8 . The healthcare footwear article, as recited in  claim 2 , wherein a thickness of said midsole member is at most 0.15 millimeter. 
     
     
         9 . The healthcare footwear article, as recited in  claim 4 , wherein a thickness of said midsole member is at most 0.15 millimeter. 
     
     
         10 . The healthcare footwear article, as recited in  claim 7 , wherein a thickness of said midsole member is at most 0.15 millimeter. 
     
     
         11 . The healthcare footwear article, as recited in  claim 8 , wherein said bottom surface of said bottom outsole portion has a plurality of indentions formed thereon. 
     
     
         12 . The healthcare footwear article, as recited in  claim 9 , wherein said bottom surface of said bottom outsole portion has a plurality of indentions formed thereon. 
     
     
         13 . The healthcare footwear article, as recited in  claim 10 , wherein said bottom surface of said bottom outsole portion has a plurality of indentions formed thereon. 
     
     
         14 . A method of manufacturing a healthcare footwear article, comprising the steps of:
 (a) providing a healthcare sole member by injection molding or pressing technology, wherein said healthcare sole member is configured from silicon rubber material, and has a bottom outsole portion, an upper insole portion, and a connecting surface;   (b) attaching a midsole member on the connecting surface of said healthcare sole member by injection molding or pressing technology;   (c) providing an upper shoe body which defines a receiving cavity and has an attachment surface, wherein said upper shoe body is configured from a material other than silicon rubber; and   (d) securely attaching said attachment surface of said upper shoe body on said connecting surface and said midsole member for securely connecting said upper shoe body to said healthcare sole member.   
     
     
         15 . The method, as recited in  claim 14 , wherein said (d) comprises the steps of:
 (d.1) applying a layer of adhesive agent onto said connecting surface of said healthcare sole member and said midsole member; and   (d.2) attaching said attachment surface of said upper shoe body to said connecting surface of said healthcare sole member and said midsole member so as to securely connect said upper shoe body to said healthcare sole member, wherein said midsole member is sandwiched between said connecting surface and said attachment surface.   
     
     
         16 . The method, as recited in  claim 15 , further comprising the step of providing at least one reinforcing fiber arranged to connect said upper shoe body and said healthcare sole member by circumferentially stitching said reinforcing fiber along said attachment surface and said connecting surface. 
     
     
         17 . The method, as recited in  claim 16 , further comprising a step of forming a plurality of indentions on said bottom surface of said bottom outsole portion. 
     
     
         18 . The method, as recited in  claim 15 , wherein a thickness of said midsole member is at most 0.15 millimeter.
