EXERCISE MACHINE

摘要

PURPOSE: An exercise machine is provided to maximize the assembling property and productivity by simplifying a power transmission structure and provide excellent exercise effect by a seesaw operation of a footboard by constantly transmitting the driving force of a motor to the left and right sides of the footboard. CONSTITUTION: A footboard(1) is provided on a base(2). The footboard(1) is fixed to a supporting shaft(7) by clamps(8), both opposite ends performing a seesaw operation for alternately lifting and falling the left and right sides upon receipt of the driving force of a motor axis(M-1) of a motor(M), thereby strengthening the body muscle force of an exerciser. A single rotary shaft(10) extending in the left and right directions is rotatably supported on a lower part of the footboard(1) to connect a single belt(V) to the motor axis(M-1), a driving pulleys(P1) and a driven pulley(P2) for driving and transmission. Eccentric shafts are formed at both opposite ends of the rotary shafts(10) to thereby isolate a plurality of actuating plates(15) so as to be rotatable.
