Abstract

<P>PROBLEM TO BE SOLVED: To provide an insole which improves air circulation in a shoe to avoid stuffiness by forming an air layer in an insole to discharge air in the insole from the toe by a weight movement and does not reduce the air amount much to enable dehumidification in a shoe although the insole is thinned as much as possible not to deteriorate the comfortability of the shoe. <P>SOLUTION: This air-circulating insole has air spaces at its toe and heel positions and, therefore, air stays in both toe and heel layers when the foot is in the air. Therefore, although it is thin, it can fill some capacity. In addition, an air inlet is at the heel position, and fresh air comes in. A valve 2 is fixed and the air does not leak. Besides, a protruding rib 12a is fixed on the insole and a space is kept between the insole and a sole. Because of this space, stuffiness is prevented and a spring for expand the air layer at the heel is no more needed. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an insole in which the inside of a shoe is hardly peeled by circulating air in the shoe by walking.

  Among the common concerns about feet, athlete's foot is a strong enemy. Recently, athlete's athlete's foot drugs are surpassed by each manufacturer, and many kinds are sold. On the other hand, many insoles are sold. This is because there are so many people with athlete's foot. If you look at the prevention methods for athlete's foot, there are frequent medications, dehumidification in shoes, and drying. For this reason, dehumidifying the shoes creates a very good environment for athlete's foot prevention. The insole currently on the market also plays a very important role in preventing athlete's foot from the point of drying the feet, but there may be something that can be expected to be even more effective.

  The insole that is usually sold is one that makes use of the material and one that has improved ventilation by making a hole in it, but since there is not much air movement, fresh air does not enter, I can't wipe out the moisture of my feet.

  However, it is too exaggerated to install a fan or use a motor for ventilation, which puts a burden on the foot and a bad appearance. It must be as simple as possible, cheap and productive.

As an improvement measure, a space layer was created between the upper and lower rubber fibers that sandwiched the insole so that fresh air could be taken into the space from the outside of the shoe. The insole has two air layers consisting of 3 buttocks and 6 toes on the insole, and the air taken into the buttocks is pushed by the scissors, passing through the 4 ventilation holes in the arch. Entering the air layer of the toe part, when the weight is on the toe, the air layer of the toe 6 is crushed, and the air in the shoes directly flows in and out of the shoe every time it walks by injecting air near the toes. This ensures that fresh air is always sent into the shoes. In addition, the product is designed to fit most shoes by reducing the thickness as much as possible by increasing the area of the air layer of the insole.
Yoshiki Miyaji / Hen "Sweetworm Q &A"

  The problem to be solved is how to circulate the air in the shoes so that the shoes can always be dried.

  The present invention has an air layer at two places, a heel and a toe, to carry and release outside air to the tip of the foot, and consists of movement of weight. In other words, when the kite is raised, air is taken into the kite's air layer. When force is applied to the kite, the air passes through the four ventilation holes without returning the air with the valve 2. When moving to the air layer of the toe and force is applied to the toe due to the movement of the body weight, air is released from the hole at the tip of the insole toward the fingertip. At this time, the air in the toe layer is prevented from returning to the bag by the 5 valve.

  The air moves from the heel to the toes, and if you keep walking, fresh air is released from the tip.

  Air circulation alone does not improve foot stuffiness. Since the sole (insole) and the sole of the foot are in close contact with each other, moisture is apt to accumulate and stuffiness occurs. To prevent this, we decided to add a horizontally long groove on the surface that hits the insole, that is, the upper surface. This further improved the air flow.

  FIG. 1 shows an embodiment of the apparatus of the present invention, which is a plan view and a simple sectional view. Air is taken from the opening of 1 and passes through 2 ball valves and enters the 3 踵 air layer. Subsequently, when force is applied to the heel, it moves through the 4 vent holes, through the 5 valve, and into the 6 toe layer. At this time, the valve 5 prevents backflow so that air does not return to the soot. The air is then pushed out of the small hole 7 and released near the finger.

  8 is a solid insole, which is intended to prevent air from accumulating in the center of the foot at the arch.

  The embodiment of FIG. 2 is an enlarged cross-sectional view of the insole. When the ball of 2a moves like 3a, air enters from the opening of 1a, but when the kite is pushed, the ball moves again to the exit, so the kite air never escapes out of the insole. . The air escape path is only in the toe direction and the air from 6a again passes through the 7a ball valve and enters the toe layer at 10a. The air that has lost its escape is released from the hole 11a. In addition, the convex part of 12a was applied so that the insole and the sole of the foot were in close contact with each other and did not get steamed.

  By keeping the air circulation insole as thin as possible, it can be used for a wide range of shoes, and at the same time, it is effective for those who are wearing shoes all day long, such as office workers, in order to eliminate stuffiness.

Claims (1)

  By providing an air layer in the insole and taking outside air into the air layer from the movement of the foot, the insole is always filled with fresh air, and on the other hand, a two-part valve provided on the insole is used. Thus, an air circulation type insole that does not allow air to escape and is released only from a specific hole is provided.
