Exerciser chair

Abstract

An exerciser chair has a main frame with a rail, a seat assembly slidably mounted on the rail of the main frame, a stop formed on the rail to limit sliding movement of the seat assembly. A front end of the main frame selectively combines with a bicycling device, footrest device or extending device. The seat assembly has arms for gripping and further has a pivotal backrest to provide a back-extending movement. Thereby, the exerciser chair has various combinations and operational selections in use.

1 . An exerciser chair comprising:
 a main frame having a rail, an ear formed at a bottom face of the rail, two stops formed at two sides of the rail;   a seat assembly slidably mounted on the main frame and having
 a sliding mount slidably mounted on the rail and has an ear formed at a bottom face of the sliding mount; 
 a resilient element connected between the ear of the rail and the ear of the sliding mount; 
 a pivoting block extending from the bottom face of the sliding mount; and 
 multiple wheels rotatably attached to the bottom face of the sliding mount to make the seat assembly smoothly slide along the rail; 
   a backrest assembly mounted on the seat assembly and having
 a backrest attached to the seat; 
 two supporting tubes attached to a backside of the backrest and pivotally connected to the pivoting block on the sliding mount; and 
 at least one resilient element connected between the sliding mount and the two supporting tubes; and 
   a foot-mounting assembly mounted at a front end of the main frame.   
     
     
         2 . The exerciser chair as claimed in  claim 1 , wherein the foot-mounting assembly is a bicycling device comprising:
 a connecting rod secured on the front end of the main frame and having a free end;   wheel assembly with a resistance-adjusting element mounted on the free end of the connecting rod;   two cranks oppositely and operationally attached the wheel assembly;   two pedals respectively mounted on two distal ends of the two cranks; and   a knob mounted on the wheel assembly to adjust the resistance-adjusting element.   
     
     
         3 . The exerciser chair as claimed in  claim 1 , wherein the foot-mounting assembly is a footrest device comprising:
 a connecting rod secured on the front end of the main frame and having a free end;   a transversal rod perpendicularly mounted on the free end of the connecting rod;   two stationary pedals respectively mounted on two ends of the transversal rod.   
     
     
         4 . The exerciser chair as claimed in  claim 1 , wherein the foot-mounting assembly is an extending device comprising:
 a connecting rod secured on the front end of the main frame and having a free end;   a T-shaped rod pivotally mounted on the free end of the main frame; and   multiple resilient elements connected between the T-shaped rod and the rail.   
     
     
         5 . The exerciser chair as claimed in  claim 1 , wherein the seat assembly further has two arms mounted on the seat. 
     
     
         6 . The exerciser chair as claimed in  claim 4 , wherein the resilient elements connected between the T-shaped rod and the rail are resilient ropes.
