ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a swing training machine for golf, throw events, racket sports etc. for learning a smooth swing motion involving twisting of the body and at the same time, strengthening and improving flexibility of arm muscles, shoulders, the body and legs (abbreviated as the swing training machine hereinafter).
DESCRIPTION OF THE PRIOR ART
Heretofore, there have been twisting machines available at a general sports club etc. as an exercising machine for twisting of the body. To use this machine, one twists his/her body by retaining the posture of the upper half of the body by holding such as a handrail and rotating the lower half of the body on a free rotary stand. The purpose of this machine is, however, to relax or improve flexibility of one's body, and not to learn the motion of sports with twisting motion or to strengthen muscles.
It is possible to strengthen muscles of the body by combining several weight training machines, but that is inefficient to strengthen the muscles mainly concerned which directly contribute to the swing motion. Although it is desirable to do the muscle training exercises with the actual motion in mind, it is difficult for beginners or those who have not yet learned the technique to associate the effect of general muscle training with swing motion characteristic of the actual event, which an expert who has learned the correct motion of the event might be able to do.
In the case of throw training such as golf swing and hammer throw, and training of racket sports such as tennis, it is difficult and inefficient to strengthen muscles required to add power to the swing, and at the same time to have technical training. It is even highly possible to twist one's waist.
SUMMARY OF THE INVENTION
The main objects of the invention are (1) to help the users learn the swing motion, which is difficult to learn by conventional techniques, in golf, throw events, racket sports etc. easily and safely, and at the same time (2) to strengthen and improve flexibility of arm muscles of arms, shoulders, the body and legs effective and efficiently when the actual motion of each event is produced efficiently.
In order to solve the said problems, as a result of his earnest research, the inventor has found that the combination of a self-rotating circular stand of a rotary motion type (abbreviated as the circular stand, hereinafter) and a motion arm of an outer circumference rotary type which rotates inversely to the said circular stand (abbreviated as the arm part, hereinafter) permits safe and easy swing motion involving twist motion of the body; and the proper combination of the said arm part, wire, an apparatus for adjusting the wire length, a handle part and an apparatus for perpendicular motion of the wire-mounted part, or the proper combination of each circular stand-apparatus, a power part and a load apparatus (preferably, a magnetic brake) permits muscle training and motion learning based on the actual motion in various sport events requiring swing motion (golf, hammer throw, tennis etc.).
