LIGHT WEIGHT SHOE SOLE HAVING STRUCTURE FOR SHOCK ABSORPTION AND ELASTIC REBOUND}

The present invention relates to a shoe sole, and more particularly, to a lightweight shoe sole having a structure that can improve impact absorption and rebound elasticity, and exhibits impact absorption and rebound elasticity that can contribute to weight reduction.

In general, shoes were developed to be worn to protect the foot, but as the quality of life has increased recently, the perception of shoes is also changing.

In particular, unlike the past, where a pair of sneakers were used for various sports, recently, functional shoes specialized for various uses such as walking, running, climbing, soccer, tennis, baseball, golf, etc. Is being developed.

In general, shoes are composed of an upper part that protects the instep and the joint area, and a sole part that protects the sole of the foot. Through the sole portion, the impact can be transmitted to the body during walking and driving, and when the sole portion is heavy, the user can easily feel fatigue, so the sole portion can cushion and absorb the impact and be provided in a light structure. It should be possible.

Accordingly, in recent years, the impact transmitted to the body during walking and driving can be minimized, and various studies have been made on the sole portion that can contribute to light weight, but there is still insufficient development of it.

The present invention provides a lightweight shoe sole having a resilient elasticity that has a shock absorbing function that can minimize the shock transmitted to the body during walking and driving, and at the same time helps energy for the next operation.

In addition, the present invention can provide an excellent fit, and provides a lightweight shoe sole that can minimize the fatigue of the foot by improving the body energy efficiency even when worn for a long time.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the lightweight shoe sole having a structure that exhibits shock absorption and resilience, the reinforcing member, the first projection supported on one surface of the reinforcing member integrally A first midsole formed and a second midsole integrally formed with a second protrusion supported on the other surface of the reinforcing member, wherein the first protrusion and the second protrusion are formed in a non-overlapping region not overlapping each other. It is supported by the reinforcing member.

A plurality of first and second protrusions may be provided spaced apart from each other at predetermined intervals along the length direction of the first and second midsoles, and first and second buffer spaces are formed between the first and second protrusions, respectively. Can be.

The shape, size, and spacing of the first and second protrusions can be variously changed according to the required conditions and design specifications, and the first and second buffers are formed by the shape, size, and spacing of the first and second protrusions. The shape and size of the space can be changed. For example, the plurality of first and second protrusions may be formed to have a substantially wave shape along the length direction of the first and second midsoles, respectively. In addition, the first and second protrusions may be provided in a continuous or integral plurality in a width direction of the first and second midsoles.

The first midsole and the second midsole may be formed of the same material to have the same elasticity and hardness, but in some cases, the first midsole and the second midsole may be formed of different materials.

In the present invention, it is understood that the first and second protrusions are supported by the reinforcing member in the non-overlapping region, so that the respective support portions of the first and second protrusions supported by the reinforcing member when the plane is transparent do not overlap each other. Can be. More specifically, in planar projection, the first protrusion may be supported by the reinforcing member on the second buffer space region, and the second protrusion may be supported by the reinforcement member on the first buffer space region. In addition, at least one of the first buffer space and the second buffer space may be formed in communication with the outside.

For example, the reinforcing member may be formed of a high elastic material having a relatively higher elasticity than the first midsole and the second midsole. In some cases, the reinforcing member may be formed of a low elastic material having a relatively lower elasticity than the first midsole and the second midsole, and the hardness of the reinforcing member and each midsole may be changed in various ways according to the required conditions and design specifications. Can be.

The structure of the reinforcing member may be changed in various ways according to the required conditions and design specifications. For example, the reinforcing member includes a reinforcing plate on which the first and second protrusions are supported, and a reinforcing rib integrally bent at a side end portion of the reinforcing plate to surround a side of at least one of the first and second midsoles. It can be configured.

The reinforcement ribs may suppress warpage that may occur during walking and running, thereby ensuring more stable walking and running, and the reinforcing ribs may be formed with a relatively thicker thickness (T2> T1) than the reinforcing plates.

In addition, at least one cut may be formed in the reinforcing plate so that the fluidity of the reinforcing member may be more stably ensured during walking and driving. Meanwhile, an exposure hole may be formed in the first midsole disposed under the reinforcing member, and a part of the reinforcing plate may be exposed to the bottom surface of the first midsole through the exposure hole.

According to the present invention, a lightweight shoe sole having a structure that exhibits shock absorption and resilience can improve energy absorption and dispersion characteristics while minimizing the shock transmitted to the body during walking and driving, and at the same time, energy for the next operation. It can improve the resilient elastic properties to help and contribute to weight reduction.

Particularly, according to the present invention, the first protrusion of the first midsole is supported by the reinforcing member made of a high elastic material in a non-overlapping region not overlapping with the second protrusion of the second midsole, thereby effectively absorbing and dispersing the shock generated during walking and driving. You can. That is, according to the present invention, since the impact force transmitted through the first and second protrusions through the reinforcing member can be uniformly dispersed and absorbed as a whole, the shock absorption and dispersion characteristics can be maximized.

In addition, according to the present invention, since the first and second protrusions are supported by the reinforcing member made of a high elastic material, it is possible to maximize the resilient elastic properties that may help energy for the next operation. In other words, the propulsive force (rebound resilience) can be improved when the vehicle is taken off and off.

Therefore, according to the present invention, it is possible to provide an excellent fit, to ensure a more comfortable walking and running, as well as to improve the body energy efficiency even during long-term wearing can minimize the fatigue of the foot.

In addition, according to the present invention, since the first buffer space and the second buffer space are formed on both sides with the reinforcing member interposed therebetween, the shoe sole can be made lighter while ensuring excellent shock absorption performance.

In addition, according to the present invention can be effectively absorbed and dispersed side impact even if the impact occurs in the side.

In addition, according to the present invention by filling the filler in the first buffer space and the second buffer space, the cushioning and shock absorbing performance degradation due to the inflow of foreign matter such as sand, gravel into the first buffer space and the second buffer space. It can prevent it beforehand.

The reinforcing member 300 is provided between the first midsole 100 and the second midsole 200, the first midsole 100 and the second midsole 200 including the reinforcing member 300 is insole ( an insole (not shown) and an outsole 400 (outsole). Hereinafter, an example in which the first midsole 100 is disposed below the reinforcing member 300 and the second midsole 200 is disposed above the reinforcing member 300 will be described. In some cases, the arrangement positions of the first midsole and the second midsole may be changed.

The first protrusion 110 is integrally formed on the upper surface of the first midsole 100. For example, the first midsole 100 having the first protrusion 110 may be formed by conventional foam molding using conventional rubber and synthetic resin, and in some cases, the first midsole 100 may be formed. It may also be formed of an unfoamed body or other materials.

The first protrusions 110 may be provided in plural to be spaced apart at predetermined intervals along the length direction of the first midsole 100, and the first buffer space 120 may be disposed between the first protrusions 110. This can be formed.

For example, the first protrusion 2110 and the second protrusion 2210 may be formed to form a substantially hollow cylindrical closed loop, and the second protrusion 2210 may be formed to have a smaller diameter than the first protrusion 2110. It may be configured to be supported by the reinforcing member 2300 in a region corresponding to the inner region of the first protrusion 2110. In some cases, the second protrusion may be formed to have a relatively larger diameter (or size) than the first protrusion, and may be configured to be supported by the reinforcing member in the outer region of the first protrusion. In addition, the first and second protrusions may be formed to have other closed loop shapes according to the required conditions and design specifications. Alternatively, the first and second protrusions may have closed loop shapes corresponding to the overall shoe shape.
