Abstract

PROBLEM TO BE SOLVED: To provide shoes with excellent bendability, durability and stability together with the elasticity of a shoe sole part and excellent ventilation to be easily put on and taken off. SOLUTION: On the bottom surface of an inner sole 1, outer soles 2, 3 and 4 are fixed or integrally formed at the three parts of a toe, the foot arch and the heel and grooves are provided on two parts. Flexible plates 5 and 6 are fixed matched with the surface of the grooves and the upper surfaces 1c and 1d of the inner sole 1 projected upwards and a downward groove are provided successively in a shoe width direction. This shoe is bent upwards by the elastic force of the flexible plates 5 and 6 deformed in an arch shape. Thus, while the flexible plates 5 and 6 are deformed by a pressure by body weight and disperse the elastic force to both side faces opposing each other of the outer sole, they are stretched in the bending direction of a joint and flexibly bend the shoe while helping the movement of the joint by the elastic force.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe which is excellent in elasticity of a shoe sole, flexibility, durability and stability, is easy to put on and take off and has good ventilation, and is suitable for foot and whole body health and exercise. Things.

[0002]

2. Description of the Related Art Conventional shoes have various shapes and functions according to their uses. In recent years, in particular, with the growing interest in the health of the foot and exercise such as walking, more flexible and resilient materials have been used for the top of the shoe covering the foot and the bottom of the shoe protecting the sole of the foot. Was. However, in order to reduce the burden on the foot when exercising such as standing up or walking, if the shoe sole is made of rubber with high elasticity, the elasticity will be less than the resistance to bending of the metatarsal joint or ankle joint. To become
There was a drawback that the flexibility deteriorated. In addition, since the bending resistance of the sole of the shoe causes cracks and wear, and also causes rubbing and tripping of the shoe, the durability and the stability also deteriorate. Further, when a fixing device such as a string is used on the upper part of the shoe to fix the foot to the shoe, it is difficult to attach and detach the foot, and there is a drawback that heat and steam generated inside the shoe are trapped.
Several methods have been proposed so far to solve the above problems. For example, the elasticity of the shoe sole
As a measure against the flexibility, an insole (Japanese Patent Publication No. 4-80681) in which a plurality of materials curved in an arcuate shape or the like are combined, and a shoe in which a protrusion on the insole is buried in a groove in an outer sole (Japanese Patent Laid-Open No. Hei.
4) In addition, as a measure for ventilation of shoes, there is a shoe sole provided with a separation type ventilation device (JP-A-8-205902).

[0003]

However, when the elasticity of the shoe sole is increased by a conventional technique as a three-layer structure composed of an inner sole, an inner sole, and an outer sole, the sole is proportional to the thickness of the layer. Since the bending resistance generated in the entire shoe sole, the inner sole and the insole, especially the protruding portion, also increases, there is a problem in the flexibility, durability and stability. Further, in the conventional technique, a hollow air bag is required at the sole of the shoe, and there is a drawback that the bending resistance increases during exhaust. An object of the present invention is to provide a shoe having excellent elasticity of a shoe sole, flexibility, durability, and stability. It is another object of the present invention to provide a shoe that can be easily attached and detached and has good ventilation without requiring a foot fixing device or a ventilation device.

[0004]

A shoe according to the present invention comprises a shoe upper made of a soft material such as leather, fiber, rubber or resin, and a soft and highly elastic material such as rubber, resin or a foam thereof. , And the sole is composed of an inner sole, an outer sole, and a bent and stretched plate. At two or more locations on the bottom surface of the inner sole, the outer sole is divided and fixed or integrally formed in the shoe length direction, and a downward groove formed by the opposing bottom surfaces of the inner sole and the outer sole is continuous in the shoe width direction. Provided. This groove allows the shoe sole to bend and stretch upward from below the shoe. Next, the surface of the bending and stretching plate is fixed to the surface of the groove, preferably in conformity with 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 center bending surface. Alternatively, similarly, after the outer bottom is fixed to or integrally formed with the bending and stretching plate, it is fixed to the bottom surface of the inner bottom. As a result, the upper and lower surfaces of the inner bottom and the downward groove protruding upward are respectively formed continuously in the shoe width direction by the bent and stretched plate deformed into an arc shape or the like, and the shoe is bent upward by the elasticity thereof. On the other hand, the pressure and impact generated when exercising, such as standing up or walking, are strongly applied to the base of the toe and the protruding part of the heel. It is known that this is a place where skin disorders such as valgus and joint disorders such as hallux valgus are likely to occur. In addition, the tension generated on the bottom surface of the outer sole due to the bending of the shoe standing on the toe and the heel is strongly applied to the base of the toe and the two places in front of the heel. It is known that Therefore, it is preferable to provide the bending and stretching plate, which is important for reducing the deterioration of the sole of the shoe together with the burden and obstacle on the foot, at the base of the toe of the sole of the shoe to improve the flexibility, durability and stability. It is particularly preferable to provide it at two places, that part and the front part of the heel. Further, it is particularly preferable that the shoes be fixed to the foot with the two bent and stretched plates, and that a gap between the inner bottom and the arch be provided to improve the detachability and ventilation.

[0005]

The pressure exerted by the bent and stretched plate deformed into an arc shape or the like is applied to both opposing side surfaces of the outer sole, while no tension is applied to the bottom surface of the outer sole because there is no resistance due to bending of the shoe. In addition, pressure by the bending and stretching plate is applied to the bottom surface of the inner bottom, and tension is applied to the protruding surface. When the shoe bent upward by the elasticity of the bending and stretching plate is stretched downward, the bending and stretching plate bends to increase the elasticity, and when bent upward, the bending and stretching plate expands and the elasticity decreases. Therefore, when the shoe is worn on the foot, the shoe is stretched by the pressure of the sole, and pressure is applied to the opposite sides of the outer sole by the elasticity of the bending and stretching plate. As a result, the shoe adheres the upper surface of the inner sole to the sole. And fix it. In particular, the bending and stretching plate secures the protruding surface of the inner bottom in close contact with the toe and the heel, while leaving a gap between the inner bottom and the arch. Next, when the pressure or impact due to the weight is applied to the sole of the foot, especially at the base of the toe and the heel by exercise such as standing or walking, the bending and stretching plate is further deformed and its elasticity is distributed to the opposing sides of the outer sole. I do. On the other hand, with the bending of the shoe standing on the toe and the heel, the flexion and extension plate stretches in the direction of bending of the metatarsal joint and the ankle joint, and the elasticity of the shoe flexes the shoe while assisting the movement of the joint, and the bottom of the outer sole To the ground. Furthermore, since the outer sole moves up and down in conjunction with the bending and stretching of the bending and stretching plate as described above, the shoe discharges and inhales the air in the gap between the inner sole and the arch from the opening at the top of the shoe, generating heat inside the shoe. And vapor to the outside.

And downward grooves are respectively formed continuously in the shoe width direction, and the bending and stretching plates 5, 6 push up the outer soles 2, 4 by the elasticity thereof to bend the shoes upward.

As shown in FIG. 4, when the shoe is worn on the foot and no pressure due to the weight is applied, the outer sole 2 is pressed by the pressure on the sole.
4 The shoe is stretched by pressing down, and the elasticity of the bending and stretching plates 5 and 6 makes the upper surface of the inner sole 1 the sole of the foot, especially the protruding upper surface 1.
While c and 1d are tightly fixed to the toe and the heel, 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 weight is applied to the sole of the foot, particularly at the base of the toe and the heel by exercise such as standing or walking, the bending and stretching plates 5 and 6 are further deformed to lose elasticity. Disperse at the bottom. On the other hand, as shown in FIG. 6 and FIG.
The shoe sole is flexibly bent while the midfoot joint or the ankle joint is stretched in a bending direction and the elasticity of the joint assists the movement of the joint, and the bottom surfaces of the outer soles 2, 3, and 4 are brought into close contact with the ground. FIG. 4
As apparent from FIG. 5 and FIG. 5, since the outer sole 3 moves up and down in the opposite direction to the outer soles 2 and 4, the shoe discharges and inhales the air in the gap between the inner sole 1 and the arch from the opening in the upper part of the shoe. To dissipate the heat and steam generated inside to the outside.

[0008]

When the shoe according to the present invention is worn and exercising such as upright or walking, the elasticity of the bending and stretching plate absorbs the pressure and shock applied to the bottom of the foot, especially the base of the toe and the heel, Can reduce the burden on the feet and leg disorders such as blisters, octopus, sea urchin, hallux valgus and sprains. Also, because the shoes flex flexibly and the bottom surface of the outer sole, especially the toes and heels, can adhere to the ground,
It is easy to bend the shoes in the state of standing on the toe and the heel, and it is possible to reduce deterioration such as cracks and abrasion, obstacles to the feet such as rubbing of shoes, and slipping or tripping of shoes. In addition, the upper surface of the inner sole can be fixed to the sole of the foot, especially the toe and heel, with the elasticity of the bending and stretching plate, without specially requiring the fixing device for the upper leg of the shoe. The shoes are well ventilated, and foot illness such as foot fatigue and athlete's foot due to heat or steam can be reduced without particularly requiring a ventilation device. Therefore, the shoe according to the present invention has elasticity and flexibility as compared with conventional shoes.
It has excellent durability and stability, and has excellent ventilation as well as detachability.
