Pedal lever distance adjusting structure for sport exercise cycle

Abstract

The present invention relates to a pedal lever distance adjusting structure mounted between a sport exercise cycle and two pedal support racks. Each of the two pedal lever support racks is provided with multiple through holes. Two adjusting tubes are each provided to mate with the pedal lever support rack, and each adjusting tube defines multiple through holes to mate with the through holes of the pedal lever support rack. An insertion pin in turn extends through the through hole of the adjusting tube, and the through hole of the pedal lever support rack. In such a manner, the distance between the pedal lever support rack and the adjusting tube can be adjusted freely, thereby facilitating adjusting the distance between two pedal levers and a human body, so that the present invention may be available for a user whose two feet have different lengths.

What is claimed is:  
     
         1 . A pedal lever distance adjusting structure of a sport exercise cycle, mounted between a sport exercise cycle that has a driving structure and two pedal support racks ( 20 ), said sport exercise cycle being driven by a driving member that includes a single direction ratchet wheel ( 10 ) co-operating with a spring ( 11 ), and said driving member being driven by a pedal lever ( 15 ) of said sport exercise cycle; 
 wherein,    each of said two pedal lever support racks ( 20 ), is pivotally provided with said pedal lever ( 15 ), and is provided with at least one first through hole ( 21 );    two adjusting tubes ( 30 ), are each secured on a front end of said sport exercise cycle, and each of said two adjusting tubes ( 30 ) axially defines a receiving channel ( 31 ) for slidably receiving a respective pedal lever support rack ( 20 ), and defines at least one second through hole ( 32 ) communicating with said receiving channel ( 31 ) and aligning with said first through hole ( 21 ) of said respective pedal lever support rack ( 20 ); and    at least one insertion pin ( 40 ), in turn extends through said second through hole ( 32 ) of said adjusting tube ( 30 ), through said receiving channel ( 31 ) of said adjusting tube ( 30 ), and into said first through hole ( 21 ) of said pedal lever support rack ( 20 ).
