Ventilated shoe with protection sheet

Abstract

An upper of a shoe is provided with a first ventilating opening which extends through the inner and outer surfaces of the upper. A flexible protection sheet is disposed over the first ventilating opening and is fixed to the upper. A second ventilating opening is defined at least by the protection sheet for cooperating with the first ventilating opening so as to ventilate the shoe, and is staggered with respect to the first ventilating opening. The protection sheet prevents contaminants from entering the shoe through the first ventilating opening while still permitting effective ventilation through the first ventilating opening.

1 . A shoe comprising: 
 an outsole;    an upper connected to said outsole, said upper having an inner surface, an outer surface, and at least one first ventilating opening extending through said inner and outer surfaces;    a flexible protection sheet disposed over said first ventilating opening and fixed to said upper;    a second ventilating opening which is defined at least by said protection sheet and which is staggered with respect to said first ventilating opening, said second ventilating opening being cooperative with said first ventilating opening to ventilate the shoe; and    a fastening unit to fix said protection sheet to said upper.    
     
     
         2 . The shoe as claimed in  claim 1 , wherein said protection sheet has a marginal end and an interior part surrounded by said marginal end, said fastening unit being attached solely to said marginal end so that said interior part is movable relative to said upper.  
     
     
         3 . The shoe as claimed in  claim 2 , wherein said protection sheet covers entirely said first ventilating opening, said fastening unit being attached to a portion of said marginal end so that said marginal end has another portion which is movable relative to said upper, said second ventilating opening being defined between said another portion of said marginal end and said outer surface of said upper.  
     
     
         4 . The shoe as claimed in  claim 2 , wherein said protection sheet is polygonal and has a plurality of sides which define said marginal end, said sides including two first sides which are substantially opposite to each other, and second sides connected to said first sides, said fastening unit being attached to said first sides, said second ventilating opening being defined between each of said second sides and said outer surface of said upper.  
     
     
         5 . The shoe as claimed in  claim 1 , wherein said fastening unit includes stitches which fasten said protection sheet to said upper.  
     
     
         6 . The shoe as claimed in  claim 1 , wherein said fastening unit includes an adhesive which cements said protection sheet to said upper.  
     
     
         7 . The shoe as claimed in  claim 1 , wherein said upper includes a plurality of said first ventilating openings.  
     
     
         8 . The shoe as claimed in  claim 1 , wherein said first ventilating opening is configured as a slit.  
     
     
         9 . The shoe as claimed in  claim 1 , wherein said upper is formed of a plurality of sheet parts which are assembled together, said first ventilating opening being defined by more than one of said sheet parts which are adjacent to each other, said more than one of said sheet parts having respective edges which are indented to cooperatively define said first ventilating opening.  
     
     
         10 . The shoe as claimed in  claim 1 , wherein said fastening unit includes hook-and-loop fasteners.  
     
     
         11 . The shoe as claimed in  claim 1 , wherein said fastening unit includes a plurality of studs.  
     
     
         12 . The shoe as claimed in  claim 1 , wherein said second ventilating opening is formed in said interior part of said protection sheet at a position which is staggered with respect to said first ventilating opening.  
     
     
         13 . The shoe as claimed in  claim 1 , further comprising an air permeable sheet which covers said first ventilating opening and which is disposed inwardly of said protection sheet.  
     
     
         14 . The shoe as claimed in  claim 13 , wherein said air permeable sheet is disposed between said upper and said protection sheet.  
     
     
         15 . The shoe as claimed in  claim 14 , wherein said air permeable sheet is provided with screen openings.
