Elevated tubing lane system

Abstract

A tubing surface for inner tubes adjustably displaced above the ground.

I claim: 
     
         1 . An elevated tubing lane system, comprising:
 a tubing surface ( 20 );   an elevation means ( 60 ) to position said tubing surface ( 20 ) above a ground;   two boundaries ( 30 ) on said tubing surface ( 20 );   an elevation means ( 60 ) supporting said tubing surface ( 20 ) above the ground.   
     
     
         2 . The apparatus of  claim 1 , further comprising:
 a slowdown strip ( 120 ) disposed on said tubing surface ( 20 ) disposed near the boundaries ( 30 ) and away from the middle of the tubing surface ( 20 ).   
     
     
         3 . The apparatus of  claim 2 , further comprising:
 said tubing lane ( 20 ) having a lower middle portion ( 130 ).   
     
     
         4 . The apparatus of  claim 3 , whereby the lower middle portion ( 130 ) is 0.68 inches lower than the edges ( 140 ). 
     
     
         5 . An elevated tubing lane system ( 10 ), comprising:
 a tubing surface ( 20 ):   said tubing surface ( 20 ) has a boundary ( 30 ) disposed leftwardly and rightwardly of the tubing surface ( 20 );   an elevation means ( 60 ) that elevates the tubing surface ( 20 ) above the ground;   a boundary lengthwise termination pointe ( 70 );   the tubing surface ( 20 ) has slow down strips ( 120 ) that have a higher coefficient of friction than the other portions of the tubing surface ( 20 );   the slow down strips ( 120 ) are made of Rough Top 150 SBR Rubber;   the slow down strips ( 120 ) are disposed on the tubing lane ( 20 ) so that the slow down strips ( 120 ) contact the outside perimeter of an inner tube ( 40 );   said tubing surface  20  is disposed between two boundaries ( 30 );   a lengthwise support means ( 80 ) supporting the tubing surface ( 20 );   an elevation means ( 60 ) elevates the tubing surface ( 20 ) above the ground  100 ;   said elevation means ( 60 ) has a lower end that is disposed on the ground ( 100 ) and an upper end that is attached to a lengthwise support means ( 80 );   a crossbar ( 90 ) is connected at each end to the elevation means ( 60 ) to assist in supporting the lengthwise support means ( 80 );   said elevation means ( 60 ) is adjustable so the tubing surface ( 20 ) can be made substantially perpendicular with respect to the direction of the force of gravity;   said crossbar ( 90 ) is disposed between each elevation means ( 60 ); said crossbar ( 90 ) is connected to the lengthwise support means ( 80 ), which supports the tubing surface ( 20 );   said tubing lane ( 20 ) has a lower middle portion ( 130 ) that causes the inner tube ( 40 ) to be forced to the middle of the tubing surface ( 20 ) via gravity; and   edges ( 140 ) are disposed on the leftwardly and rightwardly sides of the tubing lane ( 20 );   said boundaries ( 30 ) are placed above the edges ( 140 ).
