The present invention relates to a cushion and a ventilator for shoes, and more particularly to a cushion and a ventilator for shoes that can mitigate the impact of weight when walking and ventilate the air inside.

Typically, most shoes, including sneakers, are configured as soles and uppers, and the soles are in contact with the ground and absorb the shocks to the wearer, but the cushioning power is insufficient to provide the wearer with many ankle and knee joints. It is easy to apply a load and to be easily fatigued or injured.

In addition, when the shoes are worn, the feet are blocked from the outside, so the air does not pass smoothly, and thus, the smell of the feet is severe and sweat is generated, resulting in various unsanitary problems.

         Conventional means for solving this problem is formed by inserting an elastic material such as a sponge or airbag in the heel of the shoe to mitigate the impact with the ground when landing, the airbag has a passage connected to the front to the weight Each time the pressure is applied by the air inside the air bag has a structure that is introduced into the shoe through the passage.

       However, among such conventional methods, elastic materials such as sponge have little cushioning effect, and thus have little cushioning effect, and means using airbags may cause puncture when exposed parts come into contact with external objects. There is a problem that greatly increases.

       Therefore, airbags are used for some expensive sneakers, but cushioning and ventilation means are not commercialized in other shoes such as hiking boots, safety shoes, and boots.

The present invention is to overcome the above-mentioned conventional problems, the purpose of the present invention is to mitigate the impact of landing to minimize the fatigue of the pedestrians foot protection and to keep the interior of the shoe in a comfortable and clean state To provide a cushion and a ventilation device for the shoe.

Another object of the present invention is to provide a shoe cushion and a ventilator that can be produced with high durability, solid and low cost.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

       1 is an exploded perspective view of a shoe cushion and a ventilator according to the present invention, Figure 2 and Figure 3 is a cross-sectional view showing the operating state of the shoe cushion and a ventilator according to the present invention cushion and pumping means installed in the rear It is provided to mitigate the impact and at the same time the internal air is transferred to the front of the shoe by the pressure input.

The above is described in more detail as follows.

       First, the shoe sole 10 has a predetermined space portion 12 is formed in the rear, and the central passage 16 is connected to the front of the shoe from the space portion to the front. In addition, the front central passage 16 of the shoe sole is formed with one or more divided passages 18 connected to both sides. In addition, a suction hole 14 communicating with the outside is formed at the rear or the side of the space 12, and a check valve 15 is installed at the suction hole 14 to introduce external air into the inside.

      Thereafter, the space 20 of the shoe sole is fitted with a case 20 having an open upper surface. The front of the case has a hole 21 connected to the central passage and also has a hole 22 communicating with the suction hole 14.

      At least one cushion plate 22 or 23 molded in a semicircular shape by a metal or resin having a predetermined elastic force is assembled at the top of the case 20. Both ends of the cushion plate are inserted into the inner surface of the case, and both sides of the case are provided with a ruler 23 for supporting both ends of the cushion plate. On the other hand, the cushion plate may be configured as a single body, but the predetermined interval between each cushion plate (24, 25) can facilitate the inflow of air into the case of the air, which is the speed of the circulation of air It can be increased.

     In addition, the shoe sole 30 and the shoe insole 40 attached to the shoe sole 10 are formed at the upper part of the case so that a first ventilation hole 32 is formed to increase the inflow of air during pumping, and the front angle of the shoe sole 30 is increased. Whenever the air in the case is pumped by the cushion plate as the second vent 34 is formed to be located above the central passage and the split passage. Air is exhausted into the shoe.

Therefore, when the pressure input is applied to the heel by the wearer's walking as shown in Figures 2 and 3, the shock is alleviated by the cushion plate to compress the inside of the case and at the same time, the air inside the case is the central passage 16 and the split passage ( 18) is discharged to the upper vent. Afterwards, when the pressure input disappears by walking, the cushion plates 24 and 25 return to their original positions, and suction force is generated inside the case, and outside air is introduced into the case through the check valve.

As the walking is repeated in this way, the air in the shoe is continuously ventilated with the buffer.

As described above, the shoe cushion and the ventilation device according to the present invention can be produced in a relatively simple structure at a low cost, so that it can be used without significantly increasing the product price for hiking boots, boots, etc. Together it can be used for a long time without any trouble.
