Description

Shoe for absorbing impact

The present invention relates to a shock-absorbing shoe, and more particularly, to a shock-absorbing shoe that can effectively absorb the impact applied from the outside and improve the wearing comfort.

In general, during an exercise such as running, basketball, soccer and tennis, a significant impact force is applied to the athlete's feet. The impact force is transmitted to the athlete's feet whenever the athlete's shoes are in contact with the ground. The constant impact force transmitted to the athlete's foot causes the user to be inconvenient, tired and injured.

In order to absorb this impact, sneakers typically have a cushion for absorbing shock. The shock absorbing cushion is mounted to the middle sole portion of the rear of the sneaker to absorb the shock generated when the exerciser's load is applied downward.

The shock absorbing cushion may be made of an elastic material, for example, a rubber plate or a sponge, but recently, an air tube has been widely used as a shock absorbing cushion.

1 is a side view of a conventional sneaker equipped with an air tube, and FIG. 2 is a perspective view of the air tube 10 of FIG. As shown in these figures, the sneaker has an outsole 1 forming the bottom of the shoe, a midsole 3 attached to the top of the outsole 1 and an upper sole forming the top of the shoe. sole, 5). On the upper surface of the midsole (3) inside the shoe is attached an insole (insole, 7) in contact with the sole of the athlete.

Shock absorbing air tubes 10 are attached to the midsole 3 at the front and rear portions of the sneakers, respectively. As shown in FIG. 2, the air tube 10 includes an upper plate, a lower plate, and a side wall. The upper and lower plates are each made of a flexible material, and are arranged to face up and down evenly while maintaining a predetermined interval. The side plate is also made of a flexible material, and the upper part of the side plate is hermetically coupled along the edge of the upper plate, and the lower part of the side plate is hermetically coupled along the edge of the lower plate, thereby sealing the inside of the air tube 10. Hollows are formed. The hollow portion of the air tube 10 is filled with shock-absorbing air, so that when the impact force is applied to the air tube 10, the air can act as a shock-absorbing cushion.

Hereinafter will be described the operation and effects of the air tube mounted on a conventional shoe.

When an athlete wearing a sneaker having the above configuration exercises, whenever the athlete's shoes are in contact with the ground, the impact force due to the athlete's load is transmitted to the shoes. The impact force is typically applied primarily to the heel of the sneaker, then gradually moving to the front of the sneaker. The impact force applied to the sneaker is relaxed by the air of the air tube (10).

Figure 3 is a side view showing the shape of the air tube when the impact force is applied to the sneakers. As shown in this figure, when an impact force is applied to a predetermined portion of the upper plate of the air tube 10, the impact force is relaxed while the upper plate portion to which the impact force is applied is pressed downward.

However, when the upper plate is pressed downward by the impact force is applied to the upper plate, the compression force is applied to the air while reducing the gap between the upper plate and the lower plate. At this time, since the hollow portion of the air tube 10 is sealed in a state where the air is faithful, the compressed air flows to a non-compressed area in which the top plate is not pressed, and the compressed air is non-compressed. The upper and lower plates of the pressed area are inflated in the vertical direction.

Thus, a temporary bulging phenomenon occurs in the unpressed area. In addition, when the upper and lower plates of the portion bulged by the bulging phenomenon are returned to their original positions, the upper and lower plates do not maintain an even plane by being temporarily incapable of being positioned at the point of the original height by the inertia force. It does not form a curved plane. Since the bulging phenomenon occurs sequentially at various parts of the air tube 10, when the impact force is continuously applied to the air tube 10 while the upper and lower plates of the air tube 10 do not maintain a flat surface, The air tube 10 whose surface is a curved surface does not adequately relieve the impact force. Accordingly, the sneaker has a low shock-absorbing performance, there is a problem that the wearing comfort is not good.

In addition, the conventional sneakers have a structure that merely performs a role of mitigating external shock, there is a problem that it does not appeal to users who require a variety of functions and the aesthetics are reduced.

Accordingly, an object of the present invention is to solve the above problems, to provide a shock-absorbing shoes that can effectively absorb the impact applied from the outside and improve the wearing comfort.

As shown in these figures, shock absorbing shoes, for example, sneakers according to the present invention, the outsole 101 to form the bottom of the shoe, the midsole 103 attached to the top of the outsole 101, the midsole ( It is composed of an upper sole 105 attached to the upper portion of the 103 to surround the upper region to form a space for accommodating the user's foot, and a cushion for absorbing cushion 110 installed in parallel in the midsole 103 portion. have. An insole 107 is attached to the upper surface of the midsole 103 inside the sneaker to be in contact with the sole of the athlete.

Shock absorbing cushion unit 110 is mounted to the midsole 103 of the rear axle of the sneakers. As shown in FIGS. 6 and 7, the shock absorbing cushion unit 110 is vertically up and down while maintaining a predetermined distance from the upper plate 111 and the upper plate 111 at the lower portion of the upper plate 111. Consisting of the lower plate 112 and a plurality of shock-absorbing springs 113 interposed between the upper plate 111 and the lower plate 112 to alleviate the impact, and is transmitted to the user's foot from the bottom of the shoe The shock is to be alleviated by the shock mitigating spring 113.

A plurality of through holes 120 are formed on the upper plate 111 and the lower plate 112. And, in the outer periphery of the through-hole 120 of the upper plate 111 and the lower plate 112, the locking jaw is formed, respectively, the upper and lower ends of the shock-absorbing spring 113 is fixed to the locking jaw respectively up and down To be supported.

In addition, an outer cover 114 is formed to surround the upper plate 111 and the lower plate 112 to form an air chamber in which air is faithfully formed, and an impact inside the air chamber formed by the outer cover 114. The relaxation air is enriched, and the shock applied to the upper plate 111 or the lower plate 112 can be mitigated primarily. At the same time, the external shock is alleviated by the elastic force of the shock-absorbing spring 113. The upper and lower plates 111 and 112 are made of a resin material, and the outer cover 114 is made of a flexible material, for example, a flexible vinyl material.

Hereinafter will be described the operation and effect of the shock-absorbing shoes according to the present invention.

When an athlete wearing a sneaker having the above configuration exercises, whenever the athlete's shoes are in contact with the ground, the impact force due to the athlete's load is transmitted to the shoes. The impact force is transmitted to the shock absorbing cushion 110 installed on the heel of the sneaker, and is primarily relaxed by the buffering action of the air contained in the cushion 110. In addition, the impact is mitigated again by the impact relief spring 113, so that the impact force applied to the user's foot can be significantly reduced.

At this time, the upper plate 111 of the cushion portion is pressed downward by the pressure of the impact force, the compression force is applied to the air while reducing the interval between the upper plate 111 and the lower plate 112 at the pressing point. The compressed air flows to the non-pressed area in which the upper plate 111 is not pressed, thereby expanding the upper plate 111 and the lower plate 112 in the non-pressed area upward and downward.

8 is a side view illustrating a state when an impact is applied to the shoe of FIG. 6. As shown in this figure, when the pressing force by the impact is applied to the pressing point of the upper plate 111, the upper plate 111 and the lower plate 112 is inflated in the up and down direction in the non-pressed region The upper plate 111 and the lower plate 112 are subjected to swelling force. At this time, since both ends of the plurality of shock-absorbing springs 113 installed in the air chamber are pulling the upper plate 111 and the lower plate 112 inward, the upper plate 111 and the lower plate 112. ) Does not swell and maintains a flat surface. The upper and lower plates 112, in particular the upper plate 111 is to maintain a flat surface. Thus, when the impact force is continuously applied to the upper plate 111 of the cushion for absorbing shock 110, since the upper plate 111 always maintains a flat surface, the impact force is appropriately alleviated.

Accordingly, when the external impact force is applied, the impact force can be appropriately alleviated by the shock releasing spring 113 and the air inside the air chamber, and the upper plate 111 always maintains a flat surface, so that the feeling of wearing It can also be much improved compared to the prior art.
