Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manufacturing method for shoe soles, sneakers, sandals and the like, and shoe soles and inner soles for the purpose of health and diet.

[0002]

2. Description of the Related Art Among conventional health and diet shoes and sandals, there are those in which the entire heel portion is cut, those in which a part of the sole is cut, and those in which a foot contact portion has a protrusion.

[0003]

However, the conventional one with all the heels cut is tired and unbalanced because the force is always applied to the front of the foot. Conventional projections have pain when worn for a long time, and also have health problems.

[0004]

In order to solve the above-mentioned problems, the present invention balances during walking or standing by flattening the center of the sole. Due to the effect of the spring and the effect of making the inside hollow, it makes walking stable and light. In addition, the soft protrusions that have the acupressure effect are designed to touch the soles of the feet indirectly, so that it does not hurt and does not cause fatigue and can be used for a long time.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a toe and a heel of a shoe sole are cut, and shape memory alloy plates shaped into respective shoe soles are provided on the toe and the heel. And the balance of the standing position was improved.

A bellows type spring is provided at the center quadrant of the shoe sole, and a spring is recoiled by providing a stopper at the center of the spring, and the return force can be used for light movement.

A jelly-like material (for example, silicon) on the inner sole of the shoe
By providing a bag containing, it is possible to overcome individual differences in the shape of the sole.

Further, a soft (for example, silicone or rubber-like) protrusion is attached to the upper part of the bag and the place where the acupressure of the sole is located.
By putting a thin insole with a cloth on it, you can soften the contact of the protrusion with the sole of the foot.

The inside of the shoe sole is hollow to reduce the weight.

Applicable to shoes, sneakers, sandals, etc.

EXAMPLES Examples will be described with reference to the drawings.
In FIG. 1, the toe part (2) and the heel part (3) of the shoe sole are each cut to a quarter of the sole, and a shape memory alloy plate is provided at the positions (4, 5). . A stopper (7) was provided in the center of the shoe at the center two-quarters position, and bellows type springs (6) were arranged on the left and right. To protect (4,5) and make movement smooth and safe, cover the rubber bottom (4, 5) of FIG. This forms a deep groove on the side of the triangle to match the bending of (4, 5) and make it difficult to slip. To protect the central stopper and spring, place the hardened rubber in Fig. 3 on (10) and connect it to (8, 9) (4,5, 5).
The movement of 6) becomes smooth. The sole (11) is provided with a rigid and lightweight frame to make the inside hollow.

In the embodiment shown in FIG. 4, the heel is attached. The lateral groove of the rubber bottom of (9) overlaps and extends flatly to extend (5), and the entire spring is depressed by pushing the spring inside.

In the embodiment shown in FIG. 5, due to the action of returning, the forces of the plywood and the spring are overlapped with each other, and the force moves forward.

[0014]

The present invention is carried out in the form as described above, and has the following effects.

The muscles behind the legs and the muscles for stretching the muscles can be exercised, and it is particularly effective for relieving the lack of exercise for women who often wear heel shoes.

Due to the returning force of the bellows type spring and the shape memory alloy plate, the weight can be lightly moved, so that the elderly can exercise lightly.

Due to the effect of cutting the toes and the heel, the force of kicking back and forth naturally enters, and the exercise for extending the legs and the whole becomes possible without difficulty.

By providing the jelly-like bag inside the shoe, it is possible to overcome the individual differences in the shape of the sole, so that it fits the sole of the foot and does not get tired.

The projections for the acupressure of the sole of the foot are made of a soft material (for example, silicone or rubber), and a thin cloth insole coated with a cloth is laid on the projection to soften the contact with the sole of the foot. There is no reason to use it.

Since the insole can be washed, it can always be used cleanly.

In order to reduce the weight, the inside of the shoe sole is hollow so that it is light and does not easily get tired even when used for a long time.
