Exercise bike with side-to-side motion mechanism

Abstract

A bike trainer includes a rocking base having a bottom surface with an arc shaped rocking surface. A pair of support legs are each connected to a side of the base by a tilt mechanism. A main frame extends upward from the base and supports a seat. A pedal assembly is rotatably mounted to the main frame and drivingly connected to a flywheel assembly.

What is claimed is: 
     
         1 . A bike trainer, comprising:

         2 . The bike trainer according to  claim 1 , further comprising a horizontal extension extending from an upper end of the main frame and a handle bar mounted to the horizontal extension. 
     
     
         3 . The bike trainer according to  claim 1 , wherein the main frame is supported on the base by a glide assembly. 
     
     
         4 . The bike trainer according to  claim 3 , wherein the glide mechanism includes a lockout assembly. 
     
     
         5 . The bike trainer according to  claim 3 , further comprising a damper mechanism for adjustable controlling friction of the glide assembly. 
     
     
         6 . The bike trainer according to  claim 1 , wherein the pair of support legs are each pivotally connected to the base by a hinge. 
     
     
         7 . The bike trainer according to  claim 1 , wherein each tilt mechanism includes a spring that biases the pair of support legs in a downward direction. 
     
     
         8 . The bike trainer according to  claim 7 , wherein the spring is an elastomer spring. 
     
     
         9 . The bike trainer according to  claim 7 , wherein the spring is a coil spring. 
     
     
         10 . The bike trainer according to  claim 7 , wherein the spring includes a pair of elastomer springs. 
     
     
         11 . The bike trainer according to  claim 1 , wherein the arc shaped rocking surface is defined by a plurality of arc shaped bars secured to a bottom of the base. 
     
     
         12 . A bike trainer, comprising:
 a base having a pair of support legs each connected to the base;   a glide assembly supported within the base by a pair of front rollers and a pair of rear rollers each received in a respective curved track;   a main frame extending upward from the glide assembly and supporting a seat;   a pedal assembly rotatably mounted to the main frame and drivingly connected to a flywheel assembly; and   a glide damper assembly having a pad adjustably engaging a friction surface of the glide assembly.   
     
     
         13 . The bike trainer according to  claim 12 , further comprising a horizontal extension extending from an upper end of the main frame and a handle bar mounted to the horizontal extension. 
     
     
         14 . The bike trainer according to  claim 13 , wherein the glide assembly includes a lockout mechanism. 
     
     
         15 . The bike trainer according to  claim 12 , wherein the pair of support legs are each pivotally connected to the base by a hinge. 
     
     
         16 . The bike trainer according to  claim 12 , wherein each of the pair of support legs are pivotally connected to the base by a tilt mechanism that includes a spring that biases the pair of support legs in a downward direction. 
     
     
         17 . The bike trainer according to  claim 16 , wherein the spring is an elastomer spring. 
     
     
         18 . The bike trainer according to  claim 16 , wherein the spring is a coil spring. 
     
     
         19 . The bike trainer according to  claim 16 , wherein the spring includes a pair of elastomer springs. 
     
     
         20 . The bike trainer according to  claim 12 , wherein the base includes a bottom surface with an arc shaped rocking surface.
