Abstract

(57) [Summary] [Structure] A shoe 1 is mixed with a shape memory type resin material or alloy material 2, and heat is generated from a bent toe, a flat arch or heel of a person's foot when walking. When the temperature matches, the bent toe part 1a of the outsole, the flat arch part 1
The resin material or alloy material 2 was distributed and mixed so as to restore the original shapes of b and the flat heel portion 1c. Further, a plate-shaped shape memory type resin material or alloy material 3 is embedded in the outsole 1 of the shoe, and if the temperature emanates from the bent toe, the flat arch and the heel during walking, the bent toe portion 1
a The resin material or alloy material was distributed and embedded so that the flat arch 1b and heel 1c were restored to their original shapes. [Effect] Easy to walk, comfortable to wear, assists walking without placing a load on the toes, and feels less tired when worn for a long time.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a book sole in which a shape-memory type resin material or alloy material is mixed with an artificial material for a shoe sole and molded, or embedded integrally in a sandwich shape.

[0002]

[Prior Art]

 Due to the elasticity of natural or artificial materials, the outsole of a shoe flexes or restores its original shape according to the unevenness of the ground surface during walking.

Originally, it is said that a person stands by three-point support of the back of the toes, the back of the base of the toes, and the back of the heel. When walking, the back of the heel touches the ground first and then The circumference of the arch and the bottom surface of the base of the toes are in contact with the ground, then the back surface of the toes is in contact with the ground, and the entire surface of the sole is flat except the arch, and then the bottom surface of the toes and the base of the fingers. While supporting the weight on the back side, the arch and heel stand up, and at a steeper angle, the back side of the base of the toes and the back side of the toes kick the ground surface to proceed, then return to the first movement and repeat the same movement.

Therefore, even when wearing shoes, it is desirable that the outsole be shaped to conform to the state of a foot walking barefoot.

[0005]

[Problems to be solved by the device]

 For natural leather, which is the natural material of the outsole, and synthetic leather or rubber material, which is an artificial material, the toe part and the back surface of the base of the thumb bend due to the unique elasticity of the ground surface, In addition, although it restores to its original shape and so-called rolling, it is not molded from the beginning into the shape most suitable for a person to walk, so it will lose its shape during wearing for a considerable period of time and wear it. It will be difficult, and until then you have to be patient even if it is a little uncomfortable to wear.

The present invention senses the frictional temperature of heat generated from the soles of the feet according to the temperature, the walking speed, and the condition of the ground surface, and is optimal at the respective temperatures when the toes are bent, the arch and the heel are flat. Each shape is stored in the outsole, and the outsole is restored to the shape most suitable for walking to facilitate walking.

[0007]

[Means for Solving the Problems]

 Mix the shape-memory type resin material or alloy material into the artificial material that forms the outsole of the shoe, and increase the temperature at which heat is generated from the bent toe, flat arch, and flat heel of the person's foot when walking. Each of them was measured, and when it matched the measured temperature, it was restored to the original shape of the bent toe part, the flat arch part and the flat heel part of the outsole during walking. The above-mentioned resin material or alloy material is embedded in an artificial material of the outsole or in a natural material in a sandwich shape to be integrally formed, which is an outsole of a shoe.

[0008]

[Action]

 If you start walking while standing upright with the three-point support of the back of the person's toes, the back of the base of the toes, and the back of the heel, the flat heel of the outsole contacts the ground, and then the flat soil. The foot is grounded, and then the total weight is applied to the sole of the person's foot, so that the toe part from the base of the toes to the toes on the outsole is flattened, and then from the arch to the heel. The entire part is separated from the ground surface, the weight is supported by the bent toe part, and then the heel part rises at a steep angle from the arch part. Next, the heel contacts the ground, and the same motion as described above is repeated to walk.

[0009]

【Example】

 An embodiment of the present invention will be described with reference to FIG. 1. The outsole 1 is formed of a toe portion 1a, an arch portion 1b and a heel portion 1c, and the toe portion 1a and the arch portion 1b are the same as those of the outsole 1. It is formed by mixing a shape memory type resin material or a shape memory type powder alloy 2 into an artificial material such as synthetic leather material or rubber material.

The shape memory temperature of the shape memory type resin material or powder alloy is set so that when the person walks, the arch of the sole of the foot comes into contact with the back of the base of the toe, that is, the toe bends. The temperature of each part of the foot that generates heat due to contact with the walking speed and whether the ground surface has unevenness or whether it is flat is measured, and the average value of each part is used to store the shape of each part. Set to.

That is, since the arch part 1b and the heel part 1c are not substantially deformed during walking and are substantially flat, the shape at the shape memory temperature is set to a substantially flat original shape. The toe part 1a bends and stretches during walking, so-called rolling. However, if the toe part 1a is continuously formed flat from the flat arch part 1b, and the toe of the foot does not easily bend when the shoe is worn, The toe portion 1a has an original shape that rises obliquely upward from the arch portion 1b, and the original shape is the shape at the shape memory temperature.

FIG. 2 shows another embodiment, in which a shape-memory type plate-shaped resin is formed in the artificial material of the outsole of the shoe or in the natural material into the toe part 1a and the arch part 1b. Material or shape memory type alloy material 3 is embedded in a sandwich, and when the temperature of each part of the sole of the foot matches the measured temperature during walking, the bent toes of the outsole during walking, the flat arch, the flat heel The resin material or alloy material is distributed and integrally molded so as to restore the original shape of each part.

[0013]

[Effect of the device]

 When a person walks, the heel part 1c of the outsole 1 lands, then the arch part 1b lands, then the toe part 1a lands, and then the toe part 1a bends and walks backward. , Remembering that the shape memory type resin material or alloy material 2 mixed or embedded in the outsole 1 restores the heel part 1c and the arch part 1b to a flat original shape, and the toe part 1a is inclined upward. Since it remembers that it will be restored to its original shape when raised, it is most suitable for the flat shape of the heel part 1c, the arch part 1b and the bent shape when kicking the ground surface with the toe part 1a. Therefore, when walking, the shape of the sole of the person changes and the shape of the outsole 1 are almost the same, so it is easy to walk and wears well, and even new shoes are comfortable and comfortable from the beginning. .

In particular, the toe portion 1a rolls due to the elasticity of the outsole 1 itself in accordance with the situation such as a walking speed, unevenness of the ground surface, and the like. Or, because the alloy material 2 remembers, when the toes of the foot are bent and kicked backward, the toe of the foot and the toe portion 1a of the outsole 1 are almost the same in shape, which assists in walking and helps the toe of the foot. Since it does not put a strain on the wearer, it does not cause fatigue when worn for a long time.
