UNIVERSAL FITNESS MACHINE
A universal fitness machine includes an upright frame formed of a base and a post, a swivel arm mechanism, which has a transverse bar fastened to the top end of the post and two cantilever units respectively rotatably connected to the two distal ends of the transverse bar, each cantilever unit having an elastic rope that has an inner end connected to the respective cantilever unit and an outer end extending to the free end of the respective cantilever and mounted with a grip, a lifter, which has a slide coupled to the post, a seat pad affixed to the front side of the slide and two handles fastened to two opposite lateral sides of the seat pad. By means of pulling the elastic rope or lifting the lifter, the universal fitness machine is used for multiple weight-training exercises.
(a) Field of the Invention
The present invention relates to exercising machines and more particularly, to a universal fitness machine that allows the user to perform various different weight training exercises.
(b) Description of the Prior Art
People may use simple exercising apparatus at home to perform simple exercises. For performing weight training exercises to exercise the muscles of different parts of the body, different exercising apparatus may be used. For example, a sit-up bench or chair may be used for sit-up exercise; a push-up bar may be used for push-up exercise; dumbbells may be used for training arm muscles; a horizontal bar may be used for training the muscles of the back; a chest developer may be used for training the muscles of the chest; a footplate may be used for training calf muscles; a hand grip may be used for training the muscles of the hands. However, it is expensive to prepare many different exercising apparatus for training different parts of the body. When prepared various exercising apparatus are not used, the storage of these exercising apparatus is another problem to be settled.
Therefore, it is desirable to provide a universal fitness machine, which is practical for training different parts of the body and, which is collapsible to reduce the storage space when not used.
SUMMARY OF THE INVENTIONThe present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a universal fitness machine, which is formed of an upright frame, a swivel arm mechanism and a lifter for enabling the user to pull elastic ropes in the swivel arm mechanism in training the muscles of the arms, chest, back and legs, or to keep in a half squat posture and then to push up the legs and pull up the hands in training the muscles of the legs.
It is another object of the present invention to provide a universal fitness machine, which can be collapsed to reduce the dimension when not in use.
To achieve these and other objects of the present invention a universal fitness machine comprises an upright frame formed of a base and a post, a swivel arm mechanism, which has a transverse bar fastened to the top end of the post and two cantilever units respectively rotatably connected to the two distal ends of the transverse bar, each cantilever unit having mounted therein at least one elastic rope that has an inner end connected to the respective cantilever unit and an outer end extending to the free end of the respective cantilever and mounted with a grip, a lifter, which has a slide coupled to the post, a seat pad affixed to the front side of the slide and two handles fastened to two opposite lateral sides of the seat pad. By means of pulling the elastic rope or lifting the lifter, the universal fitness machine is used for multiple weight-training exercises.
Thus, the user can hold the grips with the hands to stretch the elastic ropes, thereby exercising the muscles of different parts of the body in one of a variety of exercising postures. The user can also sit on the seat pad to perform different weight training exercises, or keep in a half squat posture with the hips rested on the seat pad of the lifter and then push up the legs, thereby training the muscles of the legs. When not in use, the major parts of the universal fitness machine can be collapsed, reducing the dimension of the universal fitness machine for storage.
