Abstract

The present invention relates to a magnetic control multifunctional exercise apparatus with double cable sheave. The exercise apparatus includes a base frame having a seat pad and an adjustable back pad. Two upright bars and one support frame are disposed at rear and front ends of the base frame. The base frame further has a magnetic control retarding mechanism provided with two cable sheaves and disposed at the bottom of the rear end of the base frame. Two pull cables are connected with two drive cables of the magnetic control retarding mechanism by means of a plurality of guide pulleys. Furthermore, a flywheel of the magnetic control retarding mechanism is coupled for unidirectional rotation, thereby reaching the expected effect of the magnetic control retarding mechanism.

Claims

1. A magnetic control multifunctional exercise apparatus with double cable sheave comprising:

a base frame;

a seat pad;

a back pad;

two upright bars disposed at both sides of the rear end of said base frame;

a support frame arranged at front end of said base frame;

a magnetic control retarding mechanism provided with two cable sheaves and disposed at the bottom of the rear end of said base frame, wherein two additional pull cables are used to couple with two drive cables of the magnetic control retarding mechanism by means of a plurality of guide pulleys such that a coupled flywheel of said magnetic control retarding mechanism is rotatable in single direction, thereby reaching the expected effect of the magnetic control retarding mechanism.

2. The magnetic control multifunctional exercise apparatus of claim 1, wherein said magnetic control retarding mechanism includes two drive cables, two fixed guide pulleys, one press pulley, two winding cable sheaves, two winding wheels, two large belt wheels, two belts, two small belt wheels, two unidirectional bearings, one flywheel, one flywheel'"'"'s shaft and a magnet set, and wherein said drive cables, said fixed guide pulleys, said winding cable sheaves, said winding wheels, said large belt wheels, said belts, said small belt wheels and said unidirectional bearings constitute two sets of power transmission system which are coupled with said flywheel'"'"'s shaft by means that said small belt wheels are in contact with said unidirectional bearings such that said flywheel is driven to rotate on said flywheel'"'"'s shaft.
