Balance assembly of an exercise auxiliary system

Abstract

A balance assembly adapted for an exercise auxiliary system includes a base, a supporting seat pivotally engaged with the base, multiple springs sandwiched between the supporting seat and the base to support the base and a fixed seat slidably connected to the supporting seat via wheels mounted on opposite sides of the supporting seat. The base has two phases, a pre-movement phase and an in-movement phase. In the pre-movement phase, the base is still resulted from supporting force from the springs and in the in-movement phase, the base rocks.

1 . A balance assembly adapted for an exercise auxiliary system, the balance assembly comprising: 
 a base;    a supporting seat pivotally engaged with the base;    multiple springs sandwiched between the supporting seat and the base to support the base such that the base has two phases, a pre-movement phase and an in-movement phase, wherein in the pre-movement phase, the base is still resulted from supporting force from the springs, in the in-movement phase, the base rocks; and    a fixed seat slidably connected to the supporting seat via wheels mounted on opposite sides of the supporting seat.    
   
   
       2 . The balance assembly as claimed in  claim 1 , wherein each of the springs has a pad formed on an end thereof so that the springs are connected to a bottom face of the base via the pads.  
   
   
       3 . The balance assembly as claimed in  claim 2 , wherein the base has an extension formed on the bottom face of the base and the supporting seat has a connecting block formed on a top face of the supporting seat to correspond to the extension of the base so that a pin is able to extend through the extension and the connecting block to complete the pivotal engagement between the base and the supporting seat.  
   
   
       4 . The balance assembly as claimed in  claim 1  further comprising multiple securing devices mounted on two opposite sides of a top face of the supporting seat to selectively immobilize the base relative to the supporting seat.  
   
   
       5 . The balance assembly as claimed in  claim 2  further comprising multiple securing devices mounted on two opposite sides of a top face of the supporting seat to selectively immobilize the base relative to the supporting seat.  
   
   
       6 . The balance assembly as claimed in  claim 3  further comprising multiple securing devices mounted on two opposite sides of the top face of the supporting seat to selectively immobilize the base relative to the supporting seat.  
   
   
       7 . The balance assembly as claimed in  claim 5 , wherein each securing device includes a threaded rod securely mounted on a top face of the supporting seat and a sleeve movably connected to the threaded rod and having a path to threadingly receive therein the threaded rod such that the sleeve is able to be threadingly extended relative to the threaded rod to abut the bottom face of the base so as to immobilize the base.  
   
   
       8 . The balance assembly as claimed in  claim 6 , wherein each securing device includes a threaded rod securely mounted on a top face of the supporting seat and a sleeve movably connected to the threaded rod and having a path to threadingly receive therein the threaded rod such that the sleeve is able to be threadingly extended relative to the threaded rod to abut the bottom face of the base so as to immobilize the base.  
   
   
       9 . The balance assembly as claimed in  claim 6 , wherein the fixed seat has a track formed on two opposite sides of the fixed seat to rotatably receive therein the wheels of the supporting seat.  
   
   
       10 . The balance assembly as claimed in  claim 7 , wherein the fixed seat has a track formed on two opposite sides of the fixed seat to rotatably receive therein the wheels of the supporting seat.  
   
   
       11 . The balance assembly as claimed in  claim 8 , wherein the fixed seat has a track formed on two opposite sides of the fixed seat to rotatably receive therein the wheels of the supporting seat.
