Description

{ARTICLE OF FOOTWEAR}

The present invention relates to a shoe article, and more particularly to a functional shoe article that can improve the shock absorption and rebound elastic properties, and improve the stability.

In general, shoes have been developed to be worn to protect their feet, but as their quality of life has increased recently, the perception of shoes has also changed a lot.

Especially, unlike the previous exercise that used a pair of athletic shoes, recently, functional shoes that are customized for various purposes such as walking, running, climbing, soccer, tennis, Is being developed.

In general, the shoe consists largely of an upper part that protects the foot and joint region, and a sole part that protects the sole. Since the sole portion can transmit the impact to the body when walking and running and the sole portion is heavy, the user can feel fatigue easily, so that the sole portion can absorb and absorb the shock and is provided with a light structure Should be able to.

Accordingly, in recent years, there have been various studies on the sole that can contribute to the weight reduction, minimizing the impact transmitted to the body during walking and traveling, improving the energy efficiency of the body during walking, Development is urgently required.

The present invention provides a functional shoe article having flexibility and appropriate rigidity, and capable of inducing stable walking.

In addition, the present invention provides a functional shoe article that can be restored to the initial state quickly after the lower shock-absorbing portion for absorbing the shock deformed or tilted by the impact force.

In addition, the present invention provides a functional shoe article capable of uniformly dispersing a user's weight, improving shock absorbing and dispersing characteristics, and improving rebound resilience.

The present invention also provides a functional shoe article that can contribute to weight reduction and can simplify the structure and manufacturing process.

Also, the present invention provides a functional shoe that can provide an excellent fit feeling and can improve the energy efficiency of the body even when worn for a long time, thereby minimizing fatigue of the foot.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the functional footwear article is a midsole, a plurality of lower buffers provided in the lower portion of the midsole spaced along the longitudinal direction of the midsole, and a plurality of lower buffers And a supporting string member connecting the side of the portion, wherein the lower cushioning portions are supported by the reinforcing string members, and the reinforcing string members provide restoring force to the lower buffering portion.

The material, shape and structure of the midsole may be varied in various ways depending on the required conditions and design specifications. For reference, the midsole may be composed of a single layer, but in some cases, a plurality of the midsole having the same or similar characteristics or having different characteristics may be stacked.

The lower buffer portion may be formed to correspond to the entire portion of the midsole, or may be formed to partially correspond to a portion of the midsole, and the present invention is not limited or limited by the size and shape of the lower buffer portion.

The bottom buffer may be provided in various shapes and structures depending on the required conditions and design specifications. For example, the lower buffer portion may be formed along the width direction of the midsole, and both ends of the lower buffer portion may be disposed almost adjacent to the side end portion of the midsole. However, some of the plurality of lower buffer parts may be formed to have a relatively short length and disposed in the inner region of the midsole. In some cases, the lower shock absorber may be formed to have a curve or other geometric shape, and the present invention is not limited or limited by the size, shape, and spacing of the lower shock absorber.

In addition, the ends of the lower buffers adjacent to each other are continuously connected to each other, the plurality of lower buffers may be arranged in a zigzag form. Alternatively, the plurality of lower buffers may be approximately connected to the fishbone by continuously connecting the central portions of the lower buffers. fish bone).

In addition, the lower buffer portion may be formed of a single layer, but in some cases, the lower buffer portion composed of a plurality of layers may be used.

The plurality of lower buffer parts may be mutually supported by the reinforcing string member, wherein the lower buffer parts are mutually supported by the reinforcing string member. When the "deformation" is deformed by the impact force generated during walking and driving, the impact force is substantially supported by being supported by another adjacent lower shock absorber (hereinafter referred to as "peripheral lower shock absorber") connected through the reinforcing string member. It can be understood that the upright state of the deformed undercarriage being applied can be elastically maintained.

The reinforcing string member may be provided in various structures according to the required conditions and design specifications. For example, the reinforcing string member may be provided such that both ends thereof are connected to the side of the lower buffer part to form a closed loop. For example, the reinforcing string member may be formed to have an approximately elliptical band shape in which both ends are connected, and may be disposed to surround the side of the lower buffer part as a whole. In some cases, the reinforcing string member may be provided to form a rectangular closed loop shape or other geometric closed loop shape. As another example, the reinforcing string member may be provided in a structure in which both ends are separated from the side of the lower buffer portion. For example, the reinforcing string member may be provided in a substantially "S" shape or "C" shape with both ends separated to partially cover only one side of both sides of the lower buffer part, and may be provided by the structure and number of the reinforcing string members. The present invention is not limited or limited.

The reinforcing string member connects the side surfaces of the lower shock absorber to each other, and allows the lower shock absorber to be mutually supported, and also enables the lower shock absorber to be more elastically supported by its own elastic force. Here, the upright state of the lower shock absorber may be understood as an upright position before the lower shock absorber is deformed by the impact force generated during walking and driving.

The placement position of the reinforcing string member with respect to the lower buffer part may be variously changed according to required conditions and design specifications. For example, the reinforcing string member is floated away from the bottom of the midsole and the bottom of the midsole so that the shock absorbing performance can be actively adjusted according to the change in the amount of impact according to the intended use. It can be placed between the bottom. As another example, the reinforcing string member may be spaced apart from the lower end of the lower shock absorber and in close contact with the bottom surface of the midsole.

In addition, the reinforcing string member may be configured to include a string body connecting the side of the lower shock absorbing portion, and an extension part integrally extending to the string body and in contact with the ground. At least some of the extensions may be disposed at the bottom of the lower buffer or midsole to serve as an outsole. As such, in a structure in which the string body is connected to the side of the lower buffer part and the extension portion integrally extended to the string body is connected to the bottom surface of the lower buffer part or the midsole, the arrangement state of the reinforcing string member may be maintained more stably. . In particular, even if sudden bending occurs repeatedly in the midsole, since the reinforcing string member is connected to the side and the bottom of the lower buffer portion at the same time, the reinforcing string member is not easily detached, it is possible to stably maintain the arrangement state.

In order to more effectively absorb and disperse the impact applied to the lower shock absorber, the lower shock absorber may have a buffer space that is open to the outside. In addition, the lower buffer portion may be formed with a connection passage communicating with the buffer space, when the shock is applied to the lower buffer portion, the internal air (or external air) of the buffer space can flow through the connection passage.

According to the functional shoe article of the present invention, shock absorption and dispersion characteristics can be improved.

According to the present invention, by allowing the lower shock absorber to be supported by the reinforcing string member, the lower shock absorber can be quickly restored to an initial state after being deformed by the impact force. In particular, according to the present invention, when the lower shock absorber is deformed to be inclined with respect to the direction perpendicular to the ground, the lower shock absorber can be restored to the initial state (upright state) more quickly and elastically by the reinforcing string member.

In addition, according to the present invention can improve the impact absorption and dispersion characteristics that can minimize the shock delivered to the body, and at the same time, it is possible to improve the repulsive elasticity (propulsion force) characteristics to help the energy for the next operation.

In addition, according to the present invention, since the upright state of the lower buffer part can be more elastically supported by the elastic force of the reinforcing string member, it is possible to improve the flow stability during walking and driving, and to more effectively cushion the impact.

In addition, according to the present invention, since the reinforcing string member is disposed between the bottom of the midsole and the lower end of the lower buffer part in a floating manner, the shock absorbing performance can be actively adjusted according to the change in the amount of impact according to the intended use. For example, when a relatively small impact amount acts on the lower buffer part, only a portion of the lower buffer part corresponding to the lower part of the reinforcing string member may be configured to elastically act. All regions can be configured to act elastically. In this way, according to the present invention, the shock absorbing performance can be actively varied according to various use conditions such as during walking and running, and the shock absorbing performance optimized for each use purpose can be provided through one shoe.

In addition, according to the present invention, it is possible to enhance the comfort and stability of the shoe and to improve the energy efficiency of the body even when wearing the shoe for a long period of time, thereby minimizing fatigue of the foot.

In addition, according to the present invention, since the space between each lower buffer part can be provided as a substantially empty space, the shoe sole can be made lighter while ensuring excellent shock absorption performance. Furthermore, since the lower buffer parts spaced apart from each other can be connected by the reinforcing string member, it is possible to maintain flexibility and at the same time, the appropriate rigidity.

In addition, according to the present invention because the reinforcing string member can be disposed along the side of the lower buffer portion can create a beautiful appearance, can improve the design characteristics and improve the merchandise value.

The lower buffer part 200 is provided in the lower portion of the midsole 100 to be spaced apart along the longitudinal direction of the midsole 100. For example, the lower buffer part 200 may be formed along the width direction of the midsole 100, and both ends of the lower buffer part may be disposed almost adjacent to the side end of the midsole 100. However, some of the plurality of lower buffer parts 200 may be formed to have a relatively short length and disposed in the inner region of the midsole 100.

The lower buffer unit 200 may be formed to correspond to the entire portion of the midsole 100, or may be formed to partially correspond to a portion of the midsole 100, by the size and shape of the lower buffer unit 200 The present invention is not limited or limited. Hereinafter, the lower buffer part 200 will be described with an example formed to form an elliptic shape in the front part and the center part of the midsole 100. In addition, a rear cushion portion (not shown) that is atypically divided may be formed at the rear portion of the midsole 100.

Hereinafter, a plurality of lower buffer parts 200 extending in a substantially rod shape along the width direction of the midsole 100 are spaced apart from each other at predetermined intervals, and end portions of the lower buffer parts 200 adjacent to each other are continuously connected to each other. For example, the plurality of lower buffer parts 200 will be described by way of example in a substantially zigzag form. In some cases, the lower shock absorber may be formed to have a curve or other geometric shape, and the present invention is not limited or limited by the size, shape, and spacing of the lower shock absorber.

And a deformation in which the impact force is substantially applied by being supported by another adjacent lower buffer part (hereinafter, referred to as “a peripheral lower buffer part”) connected through the reinforcing string member 300 when deformed by the impact force generated during driving. It can be understood that the upright state of the lower buffer part can be more elastically maintained. Since the lower shock absorber 200 may be supported by the reinforcing string member 300, the lower shock absorber 200 may be restored to an initial state more quickly after being deformed by the impact force, and in particular, the lower shock absorber 200 may be grounded. Even if it is deformed to be inclined with respect to the vertical direction, the lower buffer portion 200 can be restored to the initial state (upright state) more quickly and elastically by the reinforcing string member 300.

The reinforcing string member 300 may be provided in various structures according to the required conditions and design specifications. For example, the reinforcing string member 300 may be provided such that both ends thereof are connected to the side of the lower buffer part 200 to form a closed loop. Hereinafter, for example, the reinforcing string member 300 is formed to have an approximately elliptical band shape in which both ends thereof are connected to surround the side of the lower buffer part 200 formed at the front part and the center part of the midsole 100. Let's do it. In some cases, the reinforcing string member may be provided to form a rectangular closed loop shape or other geometric closed loop shape.

The reinforcing string member 300 may be formed of a material having a relatively large strength and elasticity than the lower buffer unit 200. For example, the reinforcing string member 300 may be formed of a high elastic rubber material.

The reinforcing string member 300 connects the side surfaces of the lower shock absorber 200 to each other and allows the lower shock absorber 200 to be mutually supported, and also the lower shock absorber by its own elastic force. The upright state of 200 can be more elastically supported. Here, the upright state of the lower shock absorber 200 may be understood as an upright position before the lower shock absorber 200 is deformed by the impact force generated during walking and driving.
