Abstract

The present invention relates to a magnetic control multifunctional exercise apparatus and includes a base frame, an upright rod connected to a bottom of the base frame, a seat pad, a back pad, two hollow supporting arms pivotably connected at a top of the upright rod, a resisting arm pivotably connected at a front of the base frame and a magnetic control resisting mechanism connected to the base frame. A plurality of pulleys are utilized in combination with two ropes to connect the supporting arms, the resisting arm, and the magnetic control resisting mechanism so that a user can pull the ropes of the supporting arms or push the resisting arm. A flywheel of the magnetic control resisting mechanism will unidirectionally turn to achieve the expected magnetic resistance.

Claims

1. A magnetic control multi-functional exercise apparatus comprising:

a) a base frame having a base frame front, a base frame bottom and a cross rod;

b) an upright rod having an upright rod top and an upright rod bottom, the upright rod bottom being connected to the base frame bottom;

c) first and second hollow support arms pivotally connected to opposite sides of the upright rod top;

d) a resisting arm pivotally connected to the base frame front;

e) a back pad connected to the upright rod between the upright rod top and bottom;

f) a seat pad connected to the base frame between the upright rod and the resisting arm;

g) a magnetic control resisting mechanism having a shaft, a flywheel rotatably adjoined to the shaft by a unidirectional bearing, a pulley rotatably connected to the shaft including a spring band that compresses as the pulley rotates from a first position and applies a force to return the pulley to the first position, the magnetic control resisting mechanism rotatably connected by the shaft to the cross rod;

h) a magnetic set adjacent to, but spaced from, the flywheel, the magnetic set including an adjusting device whereby a distance between the magnetic set and the flywheel is manually adjustable; and

,

i) an operating device having a plurality of pulleys and a plurality of ropes to operably connect the hollow support arms and the resisting arm to the magnetic control resisting mechanism.
