DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to improvements of an auxiliary instrument for stretching and softening exercises.
BACKGROUND TECHNIQUE
The stretching and softening exercise is an exercise to stretch and soften muscles and tendons by gradually adding a reasonable proper force to the muscles and tendons of various parts of a human body to stretch and relax them and is a so-called stretching exercise.
There are such effects that, if this stretching exercise is carried out as a preparatory exercise before playing a sport, such unexpected injury as a muscle separation in the sport will be able to be prevented and, if it is carried out as an adjusting exercise after the end of the sport, the excitation of the muscles and tendons severely used in the sport will be tranquilized and the fatique will be quickly removed.
Further, it is endorsed by the health and physical education theory that such stretching exercise makes the body softer, keeps health and serves for beauty. Together with its handiness, the stretching exercise has recently come to be popular not only in the sport circle but also generally.
There has been no auxiliary instrument for stretching and softening exercises which have been considered to be exercises using no instrument.
The present invention is made to further elevate the effects of such stretching and softening exercise and is to provide an auxiliary instrument for stretching and softening exercises serving for exercises for stretching particularly the Achilles' tendons and calves.
DISCLOSURE OF THE INVENTION
The auxiliary instrument for stretching and softening exercises according of the present invention comprises a supporting base 1, a treading base 2 hinged at one end to this supporting base so as to be free to rise and fall and to open and close, an angle adjusting member 3 interposed between the supporting base 1 and treading base 2 so as to keep the opening and closing angle between them at a predetermined angle and a stopper 4 erected in the rear of the treading base 2 or supporting base 1. The auxiliary instrument may also comprise, a semi-cylindrical member 21 formed to be of a curved surface corresponding to the plantar arches of feet being fitted on the upper surface of the above mentioned treading base 2. The supporting base 1 may be provided with a carrying handle 5. recess 11 for containing the angle adjusting member 3 is made on the upper surface of the above mentioned supporting base 1. The connecting part 13 of the treading base 2 and the erecting part of the stopper 4 may be separated from each other to provide a heel space part on the supporting base 1.
The invention shall be described in the following with reference to the drawings.
FIG. 1 is a view showing that the supporting base 1 and treading base 2 are opened from each other with the hinged connecting part 13 as a fulcrum and the angle adjusting member 3 is inserted between the supporting base 1 and treading base 2 so as to secure the opening between the supporting base 1 and treading base 2. When a person stands on this treading base 2 with the tiptoes directed forward, that is, in the higher direction, the Achilles' tendons, calf muscles and flatfish muscles will be able to be reasonably stretched.
Further, when the person exercises to bend forward as in FIG. 1 from the standing state, such muscle parts as the muscles in the rear of the thighs, back muscle, muscle in the rear of the neck, Achilles' tendons, calf muscles and flatfish muscles will be stretched. Therefore, there are such stretching effects as the prevention of waist pain, rehabilitation of a person suffering from waist pain, recovery from fatigue by a work in a waist bending posture, prevention of the spinal curvature, cure of the spinal curvature and rehabilitation of a person having had the Achilles' tendon broken. Further, by taking such forward bent posture, anyone can easily measure the forward bent softness.
The angle between the supporting base 1 and treading base 2 must be varied in response to the softness of the body of the
