Endless belt for treadmill

Abstract

A belt device includes one or more intermediate layers each having one or more conductive wires for reducing or for eliminating static electricity. The intermediate layers each includes a number of longitudinal fibers arranged parallel to the conductive wire, and/or includes a number of lateral fibers arranged parallel to the conductive wire. An outer peripheral layer may be attached onto the intermediate layer, or having the intermediate layer engaged into the outer peripheral layer, or an inner peripheral layer may be attached onto the intermediate layer, for allowing the intermediate layer to be disposed between the outer and the inner peripheral layers.

1 . A belt device comprising: 
 at least one intermediate layer including at least one conductive wire engaged therein for eliminating static electricity.    
   
   
       2 . The belt device as claimed in  claim 1 , wherein said at least one intermediate layer includes a plurality of longitudinal fibers arranged parallel to said at least one conductive wire.  
   
   
       3 . The belt device as claimed in  claim 1 , wherein said at least one intermediate layer includes a plurality of lateral fibers arranged parallel to said at least one conductive wire.  
   
   
       4 . The belt device as claimed in  claim 1  further comprising an outer peripheral layer attached onto said at least one intermediate layer.  
   
   
       5 . The belt device as claimed in  claim 4 , wherein said at least one intermediate layer is engaged in said outer peripheral layer.  
   
   
       6 . The belt device as claimed in  claim 1  further comprising an inner peripheral layer attached onto said at least one intermediate layer.
