Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
In particular, the present invention relates to training shoes that are effective for strengthening and stretching the strength of the triceps surae, or for improving health.

[0002]

2. Description of the Related Art Muscle training of the lower leg, particularly training of the triceps surae, is very important for enhancing propulsive force in running and instantaneous force in jumping motion.

[0003] As a general training method for triceps surae, a training is carried out in which the triceps surae is stretched by riding on an inclined plate, extending the lower leg for several seconds, and simultaneously stretching the gastrocnemius and soleus muscles. Place a block of about 5 cm in height under the ball of the foot and repeat the exercise of fully raising the heel and then returning it to give the triceps surae muscle dynamic muscle endurance. Known are a training method and a training method in which a K board is used to perform two front, back, left, and right ways of standing on the K board for balance.

However, all of the above training methods are simple tools, but each requires a special tool, and daily training requires the willingness to continue, and the training method You can also do strength training on the triceps surae on a daily basis with the tip of your toes in the train, but it usually does not last long.

Therefore, in order to easily perform training and stretching without using such a special tool or without continuous will, a shoe with a flexible sole having a non-slip bottom is conventionally used. Training in which the non-flexible reinforcing plate, which is polymer-bonded to the front part of the sole and the front part is inserted and bonded between the rear part of the sole and the shoe sole, is polymer-bonded to the heel part of the lower sole of the shoe sole and the shoe heel part is omitted Shoes (Shokai Sho 55-131102)
Further, there is disclosed a reverse-sloping health footwear (No. 4-9104) which is formed by providing a front heel member in front of the sole so that the toe side of the footwear is higher than the heel side.

[0006]

By the way, in the triceps surae, the range of motion of the dorsiflexion is significantly reduced due to aging. Therefore, if only strength training is performed, the range of motion of the dorsiflexion of the joint is decreased, and the function is functionally decreased. descend. Therefore, it is necessary to stretch at the same time. Also, if you do not use balance training together, not only will it not be useful for actual competition,
It is easy to cause a sprain. In this way, if you do not fully train by studying physical functions and kinematics,
Not only will it not be possible to obtain a sufficient effect, but it will also cause unexpected problems in terms of safety and foam making.

[0007] However, the above training shoes and the reverse inclined health footwear can perform only one of triceps surae strength training and stretch training, and no balance training is suggested. In addition, there were problems such as insufficient research on fatigue, safety and foam making.

Therefore, the present invention solves such a problem, and can perform training such as strength training and balance training of the triceps surae by simply wearing and walking or running, or performing a normal sports competition. Not only that, it aims to provide training shoes that can improve muscle stretching and blood circulation in the legs, prevent sports disorders, and correct ideal running form.

[0009]

In order to solve the above-mentioned problems, a training shoe of the present invention has a sole body fixed to the bottom of a shoe main body, and the sole body is attached to the sole body from the rear portion to the rear end from the center of the entire length. It is characterized by forming a heel excision part by cutting out the rear lower part in a scooping shape, and setting the center of gravity of the shoe forward of the heel excision part and slightly forward of the center of the entire length.

Preferably, the straight line connecting the ball of the big toe and the heel of the upper surface of the sole body is inclined at about 15 ° with respect to the horizontal line of the bottom surface of the sole body when the shoe is placed in a natural state. If the heel excision part is formed so that the bottom part of the sole body inclines upward by about 25 ° with respect to the contact surface while the heel excision part is in contact with the ground, the most effective and safe muscle strength and balance training is possible. And stretch training can be performed.

[0011]

In the training shoe of the present invention, the center of gravity of the shoe is set in front of the heel excision portion and slightly in front of the center of the entire length. Therefore, if the shoe is placed on the floor normally, the sole body bottom portion comes into contact with the heel portion. It is in a state of being separated upward from the floor surface. In addition, as a basic form, it is possible to take a state in which the heel excision portion after the sole body bottom portion rear end edge portion is grounded and only the sole body bottom surface rear end edge portion is grounded.

When the user wears the training shoe of the present invention and stands upright, the sole body bottom surface is in contact with the ground and the heel portion is upwardly separated from the floor surface, that is, a state in which the tip of the toe is slightly raised, and the muscles of the foot are moderately strained. , The back muscles are stretched. Further, by wearing the training shoe of the present invention and grounding the heel excision portion after the rear edge portion of the sole bottom surface, the calf muscles and muscles are stretched, and the muscles on the front side of the abdomen are in a tense state. Further, if only the rear end edge of the bottom surface of the sole body is grounded, the balance adjusting action can be achieved.

In the training shoe of the present invention, since the lower rear part of the sole body has a scooped heel excision portion, the heel excision portion bends when landing from the heel, and the impact applied to the foot is buffered.

According to the training shoe of the second aspect, at least a portion of the insole, which is a bottom portion of the shoe main body portion, from the abutment portion of the big toe ball to the heel end portion is inclined about 15 ° with respect to the sole body bottom portion. Therefore, when wearing this training shoe and standing upright, the bottom of the foot is about 15 ° with respect to the ground contact surface.
It will be tilted. This angle is a state in which the ankle joint is at the intermediate position and has the most stable joint angle.

When the user wears this training shoe and grounds the heel excision portion after the rear edge of the bottom of the sole body,
The bottom of the foot is inclined by about 25 ° above the toe with respect to the ground contact surface, and the ankle joint also assumes a dorsiflexion position of about 25 °. In this state, the anterior stabilization mechanism, that is, the mechanism in which the muscles and the ligaments are in harmony to stabilize the function of the joint, works most efficiently,
This is a state suitable for reducing the impact on the foot.

As shown in FIG. 2, the heel excision portion 61 after the sole body bottom portion rear end edge portion 63a is grounded, that is, the sole body bottom portion rear end edge portion 63a and the heel contact surface portion 66 are grounded. In the state of being grounded to A, the bottom 63 of the sole body is on the floor A
The heel excision portion 61 to the heel ground surface portion 66 are formed so as to be inclined forward and upward by about 25 °.

The inclination angle of the heel ground contact surface portion 66 is such that the heel ground contact surface portion 66 is entirely grounded to the floor surface A when the sole body bottom surface rear end edge portion 63a and the heel ground contact surface portion 66 are grounded. It is set.

The midsole portion 7 may be formed of rubber, hard rubber, urethane foam, or any other material having a cushioning property, and its shape is, for example, as shown in FIG. The portion (toe side) 71 to the area around the ball of the big toe X is formed in a substantially flat or slightly upward slope shape, and the ball of the big toe X is formed to be flat or slightly curved, and its rear part, that is, The upper part of the ball of the toe X to the rear end is formed in an upward slope shape, and the peripheral edge is raised to form the peripheral wall portion 72. At the bottom side, the front side up to the center of the entire length is made flat. The fixed stepped portion 73 having an appropriate width is formed on the rear side thereof, and further, a cutout portion 74 is formed in a slightly arched shape and upsloped up to the rear heel end portion 65, and the rear end portion of the cutout portion 74 is formed. Slope-shaped cutting shape It is sufficient to form a heel contact surface portion 66 and.

On the other hand, in the outsole portion 8, as shown in FIG. 3, for example, a stud portion having an arbitrary shape is formed on the bottom surface portion 81, and a thick step portion corresponding to the fixed step portion 73 is formed at the rear edge portion. 82, and the side surface portion 83 at the rear end
It is sufficient that the sole body bottom surface rear end edge portion 63a is formed so as to project upward so as to form the arch-shaped heel cut portion 61 continuously with the cut portion 74. With this structure, even if a strong impact is applied to the sole body bottom portion rear end edge portion 63a, the thick stepped portion 82 serves as a cushion to cushion the impact transmitted to the foot, and the firm adhesion causes the peeling. It can prevent and improve durability.

Further, as shown in FIG. 1, the sole body 6,
If the reinforcing plate member 9 made of an iron plate, a plastic plate, or the like is inserted between the upper part of the thick step portion 82 and the vicinity of the rear end portion between the insole 5, the durability of the training shoe 1 is further enhanced. Can be increased.

Since the shoe body 2 is supported by the sole body 6 having the above-described shape, the shoe body 2 is normally placed on the floor surface A and is inclined downward to the toes, while the sole body bottom surface is attached to the floor surface A. The heel excision portion 61 after the rear end edge portion 63a is in a state of being grounded, and is in a state of being inclined upward to the toe.

Further, the heel excision portion 61 to the heel grounding surface portion 6 are so arranged that the straight line connecting the ball of the big toe X of the upper surface portion 62 and the center portion Y of the heel is inclined about 15 ° with respect to the horizontal line of the sole body bottom portion 63.
If 6 is formed, at least the portion of the insole 4 from the vicinity of the toe ball contact portion to the rear end portion is also inclined by about 15 ° with respect to the floor A. On the other hand, the heel excision portion 61 is arranged so that the sole body bottom surface portion 63 is inclined forward about 25 ° with respect to the floor surface A.
If the heel ground contact surface portion 66 is formed, the front portion of the insole 4 from at least around the toe ball contact portion is also inclined to the floor surface A by approximately 25 ° in a tip upward direction.

Although the sneaker-shaped shoe body 2 is shown in FIG. 1, it is not particularly limited to this shape, and so-called leather shoes or the like may be used, and any shape and any structure may be used.

When the training shoe 1 is formed as described above, since the center of gravity of the shoe is set in front of the heel excision portion 61 and slightly in front of the center of the entire length of the shoe, the training shoe 1 is normally placed on the floor surface A. When placed on top, the sole body bottom portion 63 is in a grounded state, as shown in FIG. In addition, if the person wears the training shoe of the present invention and stands upright, the center of gravity of the person is located at substantially the same position, that is, in front of the heel excision portion 61 and slightly in front of the center of the entire shoe length. It becomes a state. In this state of light tiptoe, the muscles of the foot are moderately tense,
Optimal state for muscle strength. At this time, the back muscles and knees are also stretched, so that the posture can be corrected.

Further, as described above, the heel excision portions 61 to heel are so arranged that the straight line connecting the ball X of the big toe and the center Y of the heel of the upper surface portion 62 is inclined about 15 ° with respect to the horizontal line of the sole body bottom portion 63. If the ground contact surface portion 66 is formed, the sole of the foot also flexes substantially at the same angle, and the ankle joint is at the intermediate position, that is, the most stable joint angle, and it is possible to further effectively strengthen the muscle and correct the posture.

When the training shoe 1 is put on and the heel excision portion 61 is grounded, that is, the sole bottom surface rear end edge portion 63a and the heel ground surface portion 66 are grounded to the floor surface A, the back of the foot is from the heel to the toe. It leans upwards to the side and can stretch the calf muscles and muscles of the foot that normally tend to shrink and become stiff.

Further, if the heel excision portion 61 to the heel ground contact surface portion 66 are formed so that the sole body bottom surface portion 63 floats above the floor surface A and inclines forward and upward by about 25 °, the soles of the soles also have substantially the same angle. Plantar flexion and ankle joint dorsiflexion of approximately 25 °. This dorsiflexion of the ankle is for walking, running, tennis, etc.
