Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides effective training for strengthening or stretching the triceps muscles of the lower limbs, or improving health, and is used by attaching to footwear such as shoes, sandals, and slippers. It is about stretching insoles.

[0002]

2. Description of the Related Art Muscle strength training of the lower leg, especially training of the triceps surae, is important for increasing the propulsive force and jumping motion in running and the like. In addition, stretching exercises are flexible exercises designed to consciously extend the muscles and tendons that support the body.For example, if they are performed as a preparatory exercise before performing sports, etc. It prevents accidents such as injury. Furthermore, it is supported by insurance physical education theory that stretching exercise increases physical flexibility, keeps youth and health, and is also useful for beauty, and in recent years it has become widely popular not only in the sports world but also widely I have.

Japanese Unexamined Patent Publication No. Hei 7-136001 discloses that a sole body is fixed to the bottom of a shoe main body, and a sole body is attached to the sole body from a rear part of a center of the full length. There is disclosed a training shoe in which a heel resection portion in which the lower rear portion up to the end is cut off in a scalloped manner is formed, and the center of gravity of the shoe is set forward of the heel resection portion and slightly ahead of the center of the entire length. The bottom of this training shoe has a forward inclination of 15 degrees, and when the rear end of the shoe sole lands, it has a rear inclination of 25 degrees.

On the other hand, Japanese Patent Application Laid-Open No. H11-299926 discloses a stepping plate having a heel stopper on the upper side of a rear end thereof, and a support for supporting the stepping plate at a desired angle. A member is provided, and on the upper surface of the plate, a desired number of engagement concave grooves for angle adjustment directed in the width direction of the plate are formed in parallel at a predetermined interval in the front-rear direction of the plate, and the support member is A pair of leg rods of a predetermined length connected and fixed at an interval corresponding to the width of the plate, and the upper ends of both leg rods are bent at right angles so as to be located on a line connecting the both leg rods in a straight line. An engaging rod to be formed and engaged with the concave groove; and the lower and upper engaging rods having a distance corresponding to a thickness of the plate between the engaging rod and the lower end of the engaging rod. Stretching assist device consisting of a supporting rod horizontally fixed between bridges It has been disclosed.

Japanese Patent Application Laid-Open No. 10-286104 discloses that in order to make the tip of the foot higher than the rear, the bottom of the tip of the footwear is raised, or the tip of the bottom is cut into a flat surface so that the toe can be raised. Thus, footwear having a tip portion higher than a rear portion is disclosed.

[0006]

SUMMARY OF THE INVENTION The above-mentioned JP-A-7-136
According to the training shoes disclosed in JP-A-001-001, not only can the triceps surae muscle strength training and balance training be performed simply by walking, running, or performing a normal sports competition while wearing the muscles, but also by stretching muscles and feet. It is said that blood circulation can be improved. However, in this training shoe, since the center of gravity of the shoe is set forward of the heel resection and slightly forward of the center of the entire length, the user must always walk or run at a forward inclination of 15 degrees. Also, when landing on the rear end of the sole, not only must you walk or run at a 25 ° rearward inclination,
Since the center of gravity of the training shoes is set slightly forward of the center of the entire length, it is required to always exercise in an unstable state. In addition, beginners lean forward 1 from the beginning.
Exercising at 5 degrees or 25 degrees backwards is not only very painful, but prolonged training is not possible. Furthermore, in order to perform this training, there was a problem that a special training shoe had to be used.

On the other hand, in the stretching aid described in Japanese Patent Application Laid-Open No. H11-299926, the stepping plate can be inclined at a desired angle and supported by simply changing the mounting position of the support member. It is possible. However, when performing a stretching exercise, this equipment is not only necessary, but also because it is necessary to perform a stretching exercise consciously, if you do not have a strong will and a sense of purpose, continue the stretching exercise. It was difficult to do.

The footwear disclosed in Japanese Patent Application Laid-Open No. 10-286104 in which the front end portion is higher than the rear portion is intended to be used when a housewife stands and works in a kitchen or the like. Because it is much higher, using it while standing would be unstable and could cause an unexpected event.

[0009]
