Description

[0001]
[Industrial application fields]
The present invention relates to a shoe suitable for foot and whole body health and exercise, which is excellent in flexibility, durability and stability as well as elasticity of a shoe bottom portion, and is easy to attach and detach and has good ventilation.
[0002]
[Prior art]
Conventional shoes have various shapes and functions according to their use. In recent years, in particular, as interest in foot health and exercise such as walking has increased, more flexible and elastic materials have been used for the upper part of the shoe that covers the foot and the sole part that protects the sole of the foot. It was. However, in order to reduce the burden on the foot during upright or walking exercises, when using a flexible elastic rubber or the like on the shoe sole, its elasticity is resistant to bending of the midfoot and ankle joints. For this reason, there is a drawback that the flexibility becomes worse. Further, the bending resistance of the shoe bottom part causes cracks and wear, and also causes shoe rubbing and stumbling, resulting in poor durability and stability. Furthermore, in order to fix the foot to the shoe, when a fixing tool such as a string is used at the upper part of the shoe, it is difficult to attach and detach the foot, and heat and steam generated in the shoe are trapped. In order to solve the above problems, several methods have been proposed so far. For example, measures for elasticity / flexibility of shoe soles are as follows: (1) Insole that combines multiple curved materials such as bows (Japanese Patent Publication No. 4-80681), and (2) The projection on the insole Shoes buried in the groove (Japanese Patent Laid-Open No. 8-182504), and a shoe sole provided with a separate type ventilation device (Japanese Patent Laid-Open No. 8-205902) as a measure for ventilation of the shoe.

[Problems to be solved by the invention]
However, when the elasticity is increased with the conventional technology (1) (2) as a three-layer structure consisting of an inner bottom, a midsole and an outer bottom, in proportion to the thickness of the layer, (1) Since the bending resistance generated in the inner bottom and the insole of (2), particularly the protrusion, is increased in the entire shoe sole of (2), there is a problem in flexibility, durability, and stability. Further, the conventional technique (3) has a drawback that a hollow air sac is required at the shoe bottom, and its bending resistance is increased during exhaustion. An object of the present invention is to provide a shoe having excellent flexibility, durability, and stability as well as elasticity of a shoe bottom. Another object of the present invention is to provide a shoe that is easy to attach and detach and has good ventilation without requiring a foot fixture or a ventilation device.
[0004]
[Means for Solving the Problems]
The shoe according to the present invention has two members: a shoe upper portion using a flexible material such as leather, fiber, rubber, and resin, and a shoe bottom portion using a flexible and highly elastic material such as rubber, resin, or foam thereof. The shoe sole portion includes an inner bottom, an outer bottom, and a bent and stretched plate. At the two or more bottoms of the inner bottom, the outer bottom is divided in the shoe length direction to be fixed or integrally formed, and the downward grooves by the opposite side surfaces of the inner bottom and the outer bottom are continuous in the shoe width direction. Provide. This groove allows the shoe sole to bend and stretch upward from the bottom of the shoe. Next, the surface of the bent and stretched plate is fixedly aligned with the surface of the groove. That is, both end surfaces of the bending and stretching plate are fixed to both side surfaces of the groove, and the bottom surface of the inner bottom is pushed up by the central bending surface. Alternatively, the outer bottom is fixed to the bent plate or integrally formed, and then fixed to the bottom surface of the inner bottom. As a result, the upper and lower grooves protruding upward are continuously formed in the shoe width direction by the bent and stretched plate deformed into an arcuate shape, and the shoe is bent upward by the elasticity. On the other hand, the pressure and impact generated during upright or walking exercise are strongly applied to the protruding part of the base of the toe and heel, and the base of the toe has a metatarsal joint. It is known that it is a place where skin disorders such as valgus and joint disorders such as hallux valgus are likely to occur. In addition, when the shoe is standing on the toe and on the heel, the tension generated on the bottom of the outer sole is strongly applied to the base of the toe and the front of the heel, where the part is generally prone to cracking and other deterioration. It is known that Therefore, it is preferable to provide a flexion and extension plate, which is important for reducing the deterioration of the shoe sole as well as the load on the foot and obstacles, at the base of the toe of the shoe sole to improve flexibility, durability and stability. In addition, it is particularly preferable to provide it in two places, that portion and the front portion of the heel. Further, it is particularly preferable to fix the shoe to the foot with these two bent and stretched plates, and to improve the detachability and the ventilation property by opening a gap between the inner bottom and the arch.
[0005]
[Action]
The pressure exerted by the bent and stretched plate deformed into an arcuate shape is applied to the opposite side surfaces of the outer bottom, while the bottom surface of the outer bottom is not resisted by the bending of the shoe and is not tensioned. Further, the pressure by the bent and stretched plate is applied to the bottom surface of the inner bottom, and the tension is applied to the protruding surface. When a shoe bent upward due to the elastic force of the bent plate is stretched downward, the bent plate is bent to increase its elasticity, and conversely when bent upward, the bent plate is extended to reduce its elasticity. Therefore, when the shoe is worn on the foot, the shoe is stretched by the pressure from the bottom of the foot, and as a result of the pressure applied to the opposite side surfaces of the outer bottom due to the elasticity of the bent and stretched plate, the shoe adheres the upper surface of the inner bottom to the bottom of the foot. And fix. In particular, the bent plate stretches and fixes the protruding surface of the inner bottom in close contact with the toe and heel, while opening a gap between the inner bottom and the arch. Next, when the pressure or impact due to body weight is applied to the bottom of the foot, especially the base of the toes, during exercise such as upright or walking, the flexion and extension plate is further deformed and the elasticity is distributed to the opposite side surfaces of the outer bottom. To do. On the other hand, the flexion and extension plate stretches in the bending direction of the middle ankle joint and ankle joint by bending the shoe standing on the tiptoe and flexing the shoe flexibly while assisting the movement of the joint with the elasticity, and the bottom surface of the outer sole Is in close contact with the ground. Furthermore, since the outer bottom moves up and down in conjunction with the bending and stretching of the bending and stretching plate as described above, the shoes exhaust and inhale the air in the gap between the inner bottom and the arch from the opening at the top of the shoe, and the heat generated inside And dissipate steam.

【Example】
The shoe according to this example is composed of a shoe upper portion using a soft leather and a shoe bottom portion using a soft and elastic rubber. As shown in FIGS. 1 and 2, on the bottom surface of the inner bottom 1, Outer bases 2, 3, and 4 are fixedly or integrally formed at three locations of the arch and heel, respectively, and the two outer bases 1a at the base of the toe and the bottom 1b at the front of the heel are respectively opposed to the outer bottom. Grooves 7 and 8 are provided by the side surfaces 2a and 3a and 3b and 4b. Next, as shown in FIG. 3, the surfaces of the bent and stretched plates 5 and 6 are fixedly aligned with the surfaces of the grooves 7 and 8, respectively. That is, both end surfaces of the bent and stretched plates 5 and 6 are fixed to both side surfaces of the grooves 7 and 8, and the bottom surfaces 1a and 1b of the inner bottom 1 are pushed up by the central bent surfaces. As a result, the upper and lower surfaces 1c and 1d of the inner bottom 1 projecting upward and the downward grooves are continuously formed in the shoe width direction by the bent and stretched plates 5 and 6 deformed into an arcuate shape. The shoes are bent upward by pushing up the outer soles 2 and 4 by elasticity.
[0007]
As shown in FIG. 4, when the shoe is worn on the foot and no pressure is applied due to the weight, the shoe is extended by pushing down the outer bottoms 2 and 4 with the pressure from the bottom of the foot. The upper surface of 1 is fixed to the bottom surface of the foot, particularly the protruding upper surfaces 1c and 1d to the toes and heels, while a gap is formed between the upper surface of the inner bottom 1 and the arch. Next, as shown in FIG. 5, when pressure or impact due to body weight is applied to the bottom of the foot, especially the base of the toes, during exercise such as standing or walking, the flexion and extension plates 5 and 6 are further deformed to release the elasticity. Disperse to the bottom. On the other hand, as shown in FIG. 6 and FIG. 7, the bent and stretched plates 5 and 6 are stretched in the bending direction of the middle ankle joint and the ankle joint due to the bending of the shoes standing on the toe and the heel, and the elasticity of the joints is exercised by the elasticity. While helping, the shoe sole is flexed flexibly so that the bottom surfaces of the outer soles 2, 3 and 4 are in close contact with the ground. Further, as is apparent from FIGS. 4 and 5, the outer bottom 3 moves up and down in the opposite direction to the outer bottoms 2 and 4 so that the shoe exhausts the air in the gap between the inner bottom 1 and the arch from the opening at the top of the shoe.・ Inhale and dissipate heat and steam generated inside.
[0008]
【The invention's effect】
When wearing shoes according to the present invention and exercising such as standing up and walking, absorb the pressure and impact applied to the bottom of the foot, especially the base of the toes and the heel with the elasticity of the bent and stretched plate, Can reduce leg disorders such as bean, octopus, corn, hallux valgus, sprain. In addition, the shoe flexes flexibly so that the bottom of the outer bottom, particularly the toe and heel, can be in close contact with the ground, making it easy to bend the shoe while standing on the toe, causing deterioration of cracks, wear, etc. It is possible to reduce obstacles and slipping or tripping of shoes. In addition, it is easy to attach and detach because the upper surface of the inner bottom can be in close contact with the bottom of the foot, especially the toe and heel, with the elasticity of the bent plate without the need for a foot fixing tool at the top of the shoe. The ventilation of shoes is improved, and foot diseases such as foot fatigue and athlete's foot caused by heat and steam can be reduced without the need for a ventilation device. Therefore, the shoes according to the present invention are superior in elasticity, flexibility, durability, and stability, and in addition to detachability and ventilation, compared to conventional shoes.
