Fitness apparatus for chest expansion and tension pulling

Abstract

A fitness apparatus for chest expansion and tension pulling mainly includes an arcuate support board, two oscillating rod bodies and one or more than one elastic bodies, wherein the central area on the external portion of the arcuate support board is soldered with an axle seat provided for pivotally conjoining two rotary pivot housings at the rear ends of the two oscillating rod bodies; two cotters respectively and pivotally position the two oscillating rod bodies onto the axle seat. The front end of the oscillating rod body is a grip rod while the middle rear segment thereof is disposed with a bush for housing one or more than one elastic bodies. When in operation, the arcuate support board pushes against and positions at the user's abdominal portion providing a stable point for force exertion. Therefore, the two oscillating rod bodies elastically expand and close in a smooth operation to avoid sport injury and sway so as to increase stability and correctly implement tension.

1 . A fitness apparatus for chest expansion and tension pulling comprising: 
 an arcuate support board, two oscillating rod bodies and one or more than one elastic bodies, wherein the central area on the external portion of the arcuate support board is soldered with an axle seat provided for pivotally conjoining two rotary pivot housings at the rear ends of the two oscillating rod bodies; two cotters respectively and pivotally position the two oscillating rod bodies onto the axle seat; the front end of the oscillating rod body is a grip rod while the middle rear segment thereof is disposed with a bush for housing one or more than one elastic bodies;    when in operation, the arcuate support board pushes against and positions at the user's abdominal portion providing a stable point for force exertion; therefore, the two oscillating rod bodies elastically expands and closes to have a smooth operation and avoid sport injury.    
     
     
         2 . A fitness apparatus for chest expansion and tension pulling according to  claim 1 , wherein a pair of positioning hook and loop band of is disposed backwardly on the arcuate support board to circle around the user's abdominal portion for reinforcing its position on the arcuate support board.  
     
     
         3 . A fitness apparatus for chest expansion and tension pulling according to  claim 1 , wherein a soft pad is disposed on the inner lateral plane of the arcuate support board.  
     
     
         4 . A fitness apparatus for chest expansion and tension pulling according to  claim 1 , wherein the arcuate support board is unitarily molded with a plurality of protruding massage beads disposed on the inner lateral plane thereof to not only achieve the effect of fitness exercise, but also increasing the massage effect.
