Skate fitness car

Abstract

A skate fitness car includes left and right support rods having a front end pivotally coupled to a vertical pipe and freely swayed sideway, a rear end pivotally coupled to a rear driving wheel module for automatic position restorations, and a link rod pivotally coupled between the left and right support rods. If a user releases the link rod and applies forces by both legs to bring together and separate the left and right support rods, the left and right rear driving wheels can be rolled forward in an S-shaped path. A front compacting wheel below the vertical pipe is provided for driving a car body to move forward. If the user locks the link rod, the user can apply forces to the left and right support rods by both legs or twist the body to roll the left and right rear driving wheels forward in an S-shaped path and drive the front compacting wheel to slide the car body, so as to achieve the multiple operating modes and give more funs to the fitness exercise.

1 . An improved skate fitness car, comprising:
 a vertical pipe, having a handlebar and a front compacting wheel installed at top and bottom of the vertical pipe respectively; left and right support rods, each having a carrier, with a front end pivotally coupled to the vertical pipe, and a rear end installing a rear driving wheel module of a rear driving wheel; characterized in that the left and right support rods are pivotally coupled to the vertical pipe and freely swayed sideway, and the rear driving wheel module is pivotally coupled to the left and right support rods and freely swayed for automatic position restoration and correction, and a link rod is pivotally coupled between the left and right support rods; thereby the link rod is selectively connected and a user can stand on the left and right carriers to apply forces by the user's legs or twist the user's body to bring together or separate the left and right carriers, so as to drive the rear driving wheel of the rear driving wheel module to slide a car body forward in an S-shaped path.   
     
     
         2 . The improved skate fitness car of  claim 1 , wherein the front end of the left and right support rods is pivotally coupled to an extended arm by a pivot, and the extended arm and the carrier rods are locked and controlled by a lock element. 
     
     
         3 . The improved skate fitness car of  claim 2 , wherein the extended arm of the left and right support rods includes a bushing disposed at a front end of the extended arm, pivotally coupled and freely rotated up and down the vertical pipe. 
     
     
         4 . The improved skate fitness car of  claim 2 , wherein each extended arm at the front end of the left and right support rods includes a corresponding shock absorber, and the left and right shock absorbers are stopped by each other when the left and right support rods are separated from each other with a predetermined maximum angle. 
     
     
         5 . The improved skate fitness car of  claim 1 , wherein the link rod has an end movably coupled to the left and right support rods by a pivot, and another end is selectively locked by a lock element, such that if the lock element is locked, then the left and right support rods will be combined integrally and swayed by using the vertical pipe as a turning point, and if the lock element is released, then the left and right support rods will be separated from each other and swayed by using the vertical pipe as the turning point. 
     
     
         6 . The improved skate fitness car of  claim 1 , wherein the rear driving wheel of the rear driving wheel module is pivotally coupled to a rear end of the carrier rod and eccentrically compressed by the rear fork and a slanting rotating pivot.
