Description

  The present invention relates to footwear, and more particularly, to footwear that can contribute to health promotion by enabling active movement of toes inside.

  In recent years, many people suffer from foot diseases such as hallux valgus by wearing shoes. Toe illness also affects leg calves and knees, and if worse, it can cause back pain.

  Such toe disease is often caused by wearing shoes that do not fit the foot. In addition, even when wearing shoes that fit the foot, there is a small space where the toes can move inside the shoe, so the blood circulation of the toes may gradually worsen while wearing shoes for many years. .

  In particular, many modern shoes are designed to be in close contact with the soles and backs of the feet, so there are no gaps above and below the toes, and the toes may be worn with the toes fixed. Many.

  Since the foot has a pumping action as called the second heart and promotes blood circulation, if the foot does not function normally, blood circulation is deteriorated and there is a possibility of causing diseases of the circulatory system.

  Therefore, to prevent toes and other body part illnesses, even with shoes on, the toes can move sufficiently, and the toes can be actively trained and toes It is necessary to be able to increase muscular strength.

  On the other hand, in various sports, regarding the basic motions such as running, jumping, hitting, etc., all of them are basically gripping the ground with toes. That is, by consciously grasping the ground with the toes, the body can be firmly fixed to the ground, and exercises such as running, jumping and striking can be performed more accurately and effectively.

However, in recent sports shoes, as with ordinary shoes, from the viewpoint of protecting the foot, it has been created to fix the foot with a material such as leather, inside the toes,
In particular, there are few things that can move freely in the vertical direction and perform operations such as grabbing the ground.

  Therefore, from the viewpoint of sports medicine and mechanics, it is possible to freely move around by fitting to the foot. At the same time, when running, jumping, swinging golf, baseball, tennis, etc., the toes grab the ground. There is a demand for sport shoes that can be worn.

From the above viewpoint, shoes and footwear described in Patent Document 1 and Patent Document 2 are known.

The upper 13 does not have a shape capable of covering the entire instep, unlike the leather shoes 12 of the first embodiment and the sports shoes 25 of the second embodiment, and only the front half of the foot can be inserted. It is formed in a substantially bag shape.

  Since the materials of the insole 18, the midsole 14, the shock absorbing member 19, the outsole 16, and the upper 13 are the same as those of the leather shoes 12 of the first embodiment, the description thereof is omitted.

  As shown in FIG. 6, the shock absorbing member 19 has a front end cut out (reference numeral 20 indicates the cut out portion), and is fixed to the upper surface side of the midsole 14 by adhesion. Accordingly, a gap 21 is formed in front of the shock absorbing member 19 and above the midsole 14.

  As shown in FIG. 6, an elastic member 22 formed of synthetic latex 33 is disposed in the gap portion 21 along the width direction of the midsole 14. The elastic member 22 is also formed so that the upper surface portion bulges upward and has an inclined portion 23 on the tip side, and the planar shape is substantially crescent like the elastic member 22 of the first embodiment.

  The elastic member 22 has an appropriate rigidity and can obtain a repulsive force when pressed with a toe. Therefore, an appropriate load is applied when the toes are moved downward.

  As shown in FIG. 6, the impact absorbing member 19 is covered with the insole 18 at the top. Since the front end portion of the insole 18 is not cut out like the shock absorbing member 19, the gap portion 21 and the elastic member 22 are also covered and concealed by the insole 18.

The insole 18 is formed of a flexible material. When the toes are bent downward, the insole 18 is pushed by the toes and bent downward to be immersed in the gap 21. Therefore, when the toe is bent downward, the toe can be accommodated in the gap 21.
The insole 18 can be covered with an insole (not shown) on the entire upper surface or the rear half.

  The slipper 27 is configured to be used as a rehabilitation device. In order to effectively perform the rehabilitation exercise, the slipper 27 includes an outer surface portion of the upper 13 as shown in FIGS. 6 and 7. The counter 29 is provided with a liquid crystal display unit 30.

The counter 29 is configured to measure the number of movements when the toes are moved in the vertical direction.
That is, as shown in FIG. 6, in the gap portion 21 of the bottom portion 17, a pair of contact switches 31 and 32 are arranged at opposing positions on the lower surface portion of the insole 18 and the upper surface portion of the midsole 14, and the toes When bent downward, the insole 18 is also bent downward, and the switches 31 and 32 come into contact with each other to send a signal to the counter 29.

If you move the toes up and down while counting the number of times as described above, it will be immediately recognized if the toes are not enough or not enough, and if they are not enough, continue toe up and down further As a result, sufficient exercise can be performed on the toes. Further, if the number of times is sufficient, the exercise can be stopped there, so that an excessive load is not applied to the toes.
The muscle strength on the shin side of the leg can be trained by moving the toes upward, and the muscle strength on the calf side of the legs can be trained by moving the toes downward.

Next, the operation of the above embodiment will be described.
As shown in FIGS. 1 and 3 to 6, the leather shoes 12, the sports shoes 25, the sandals 26, and the slippers 27 as the footwear 11 according to the embodiment have the toes at the front end portion of the bottom portion 17. Since the gap 21 that can be bent downward is provided, the toe can be accommodated in the gap 21 when the tip of the toe is bent downward. Therefore, the exercise | movement which moves a toe up and down is attained, and blood circulation can be promoted and health can be promoted by performing this exercise.
As shown in FIGS. 1 to 6, the gap portion 21 is provided with an elastic member 22 that is elastically deformed when the toe of the toe is bent downward and can apply a repulsive force to the toe. Therefore, when the toe is bent downward, the elastic member 22 receives a repulsive force, and a load is applied when the toe moves up and down. Therefore, the muscle strength of the toes can be strengthened by repeatedly performing the exercise of bending the toes downward, and knee pain and back pain can be prevented.

Further, as shown in FIGS. 1 and 3 to 6, the bottom portion 17 of the footwear 11 has an insole 18 and a midsole 14, and an impact absorbing member 19 is disposed between the insole 18 and the midsole 14. When the tip of the impact absorbing member 19 is notched, the gap 21 is formed, and the toes are bent downward without going through a complicated process of forming a recess in the bottom 17. The gap 21 for accommodating the toes can be easily formed.
Further, as shown in FIGS. 1 and 3 to 6, the elastic member 22 is formed so that the upper surface portion protrudes upward and the tip end side is inclined, so that the toes along the inclined portion 23 are formed. Can be easily bent downward. Further, since the elastic member 22 is fixed by bonding along the width direction of the midsole 14, a complicated process of embedding and fixing the elastic member 22 in the recess is not necessary.

  Further, as shown in FIG. 3, the elastic member 22 is covered with the insole 18 and the insole 18 is formed of a flexible material that can be deformed when the toes are bent downward. When the toes are bent downward, the insole 18 also follows and deforms, so that the toes can be accommodated in the gap 21 without hindrance. Further, since the insole 18 conceals the elastic member 22, the footwear 11 where the front end portion of the bottom portion 17 such as the sandal 26 is exposed looks good.

  Further, since the elastic member 22 is formed of the synthetic latex 33 having a rigidity that can be deformed when the toes are bent with an appropriate pressure by the toes, the toes are moved downward. An appropriate load can be applied to the toes when a bending exercise is performed.

Also, as shown in FIG. 4, since the footwear 11 is configured as a sports shoe 25, the ground can be firmly grasped with toes, so that the basic operations of sports such as running, jumping and hitting can be ensured. It can be carried out.
In addition, as shown in FIG. 5, the footwear 11 is configured as a sandal 26, so that even when going out casually, the toes are sufficiently exercised to cause diseases such as feet, knees, and lower back. Can be prevented.
Further, as shown in FIGS. 6 and 7, the footwear 11 is configured as a slipper 27, so that even when in the room, the toes are sufficiently exercised to cause diseases such as feet, knees, and waist. Can be prevented.

Further, as shown in FIGS. 6 and 7, the footwear 11 is configured as a rehabilitation device 28 so that not only a healthy person but also a person who already has a disease such as a foot, a knee, and a waist can heal them. The footwear 11 can be used.
Further, as shown in FIG. 6, the rehabilitation device 28 is provided with a gap portion 21 in which the toe of the foot can bend downward at the front end portion of the bottom portion 17. It is formed as a slipper 27 provided with an elastic member 22 capable of elastically deforming and applying a repulsive force to the toes, so that the body can be moved by moving the toes up and down and moving the toes sufficiently. Blood circulation can be promoted, and muscle strength of the toes can be trained using the repulsive force of the elastic member 22.
In addition, if you move your toes upward, you can train the muscle strength on the shin side of the leg, and if you move your toes downward, you can train the muscle strength on the calf side of the leg, so you can train your legs forward and backward. It is extremely effective in restoring the function of the foot with disease.

Further, as shown in FIGS. 6 and 7, the rehabilitation device 28 is provided with a counter 29 that can measure and display the number of movements of the toes in the vertical direction. The number of exercises in the vertical direction of the toes can be easily recognized by looking at the displayed numbers. Therefore, it is possible to immediately recognize whether the toe's vertical movement is insufficient or sufficient, and if it is not enough, the toe's movement can be continued. It can be carried out.
In the above embodiment, the elastic member formed of synthetic latex has been described as an example, but is not limited to the above embodiment, and is formed of a synthetic resin material having flexibility and a certain rigidity, The front end portion of the midsole 14 may be formed by a leaf spring member having a predetermined width disposed below the insole 18 and disposed along the width direction of the midsole 14, and is not limited to the above-described embodiment.
