Sitting type stepper

Abstract

A sitting type stepper includes a stationary base having a support frame, a seat provided on the support frame, and a stepping assembly. The stepping assembly is provided on the stationary base, including two transmission units pivoted on the support frame of the stationary base, and each of the transmission unit has a handle and a pedal connected to the handle that the pedal is moved by swinging the handle.

1 . A sitting type stepper, comprising:
 a stationary base having a support frame;   a seat provided on the support frame; and   a stepping assembly, which is provided on the stationary base, including two transmission units pivoted on the support frame of the stationary base, and each of the transmission unit having a handle and a pedal connected to the handle that the pedal is moved by swinging the handle.   
     
     
         2 . The sitting type stepper as defined in  claim 1 , wherein each of the transmission units further includes an operating bar, which has a first end and a second end, pivoted on the support frame, a four-linkage mechanism, and a linkage having opposite ends connected to a second end of the operating bar and the four-linkage mechanism, and further wherein the handle is connected to the first end of the operating bar, and the four-linkage mechanism is pivoted on the support frame, and the pedal is connected to the four-linkage mechanism. 
     
     
         3 . The sitting type stepper as defined in  claim 2 , wherein the stepping assembly further includes a resistance device, which is provided on the support frame, including a belt having an end connected to the four-linkage mechanism and a spring having opposite ends connected to the support frame and the belt. 
     
     
         4 . The sitting type stepper as defined in  claim 3 , wherein the resistance device further includes a plurality of guiding wheels and a belt wheel pivoted on the support frame that the belt runs around the guiding wheels and the belt wheel in sequence. 
     
     
         5 . The sitting type stepper as defined in  claim 1 , wherein the stationary base further includes a base frame, on which the seat and the support frame are provided. 
     
     
         6 . The sitting type stepper as defined in  claim 5 , wherein the seat is provided with a sliding base engaging the base frame, and a control device provided on the sliding base with an end against the base frame. 
     
     
         7 . The sitting type stepper as defined in  claim 6 , wherein the seat is above the stepping assembly.
