A shock absorber system connectable to a roller ski wheel shaft

Abstract

A shock absorber system according to the present invention is connectable to a shaft ( 16 ) supporting a roller ski wheel ( 13 ), wherein a circular shaped rubber or rubber like material ( 10 ) is arranged around a centered position ( 11 ) of a wheel support ( 14 ) supporting an end part of the shaft ( 16 ) supporting the roller ski wheel ( 13 ).

1 . A shock absorber system connectable to a shaft ( 16 ) supporting a roller ski wheel ( 13 ) comprising:
 a wheel support ( 14 ) configured with at least one arm being insertable into at least a backend of a roller ski body ( 15 ),   a circle shaped end section ( 21 ) of the at least one arm of the wheel support ( 14 ) comprises a centered position ( 11 ) configured to support an end part ( 18   a ,  18   b ) of the shaft ( 16 ) supporting the roller ski wheel ( 13 ), characterized by:   a circular shaped rubber or rubber like material ( 10 ) is arranged around the centered position ( 11 ) supporting the end (part  18   a ,  18   b ) of the shaft ( 16 ) supporting the roller ski wheel ( 13 ).   
     
     
         2 . The system of  claim 1 , wherein the wheel support ( 14 ) comprises two members ( 14   a ,  14   b ) wherein one member is a mirrored version of the other member, wherein the shaft ( 16 ) is supported in between the two members ( 14   a ,  14   b ). 
     
     
         3 . The system of  claim 1 , wherein the shaft ( 16 ) is configured with a ball bearing ( 17 ) constrained to rotate in one forward direction supporting the roller ski wheel ( 13 ). 
     
     
         4 . The system of  claim 1 , wherein the shaft ( 16 ) is configured with respective indents in the respective end parts ( 18   a ,  18   b ) having at least one flat surface forming a tap like protruding element configured to be insertable into adapted holes ( 22   a ,  22   b ) located at the centered position ( 11 ) of the end section ( 21 ) of the at least one arm. 
     
     
         5 . The system of  claim 4 , wherein the respective indents in the respective end parts ( 18   a ,  18   b ) of the shaft ( 16 ) is configured with a threaded hole ( 20 ) in an end surface of the shaft ( 16 ) orthogonal to the at least one flat surface of the respective indents of the respective ends ( 18   a ,  18   b ). 
     
     
         6 . The system of  claim 5 , wherein a bolt or screw ( 12 ) is configured to fasten a wheel ( 13 ) to the shaft ( 16 ) when inserted into the threaded hole ( 20 ) of the shaft ( 16 ). 
     
     
         7 . The system of  claim 1 , wherein a circular shaped space in the end section ( 21 ) comprises the rubber or rubber like material ( 10 ) and a first zigzag shaped metal part ( 26 ) running along the periphery of the circular shaped space, and a second metal part ( 28 ) attachable to the shaft ( 16 ) is configured with two opposite outwardly pointing extensions adapted to fit inside adapted openings in the zigzag pattern of the first metal part ( 26 ). 
     
     
         8 . The system of  claim 7 , wherein a clearance opening ( 25 ) is configured between the outwardly extending extensions of the second metal part ( 28 ) and the zigzag shaped first metal part ( 26 ). 
     
     
         9 . The system of  claim 8 , wherein a width of the respective outwardly pointing extensions of the second metal part ( 28 ) is defined to provide a certain dimension of the clearance ( 25 ). 
     
     
         10 . The system of  claim 9 , wherein the second metal part ( 28 ) is changeable, wherein respective metal parts ( 28 ) are arranged with different widths of the outwardly pointing extensions of the second metal part ( 28 ). 
     
     
         11 . The system of  claim 1 , wherein the wheel ( 13 ) is configured with an indent ( 13   a ) running around a periphery of the wheel ( 13 ) along a centered line, wherein side surfaces of the indent are inclined downwards towards a bottom surface of the indent ( 13   a ). 
     
     
         12 . Use of a system according to any  claim 1-11  in a scooter.
