Description

A sole for health footwear having a barefoot technology}

The present invention relates to a side tunnel protrusion type shoe sole, and more particularly, when the wearer wears shoes and the weight of the wearer is loaded on the auxiliary midsole, the midsole side preventing projection member is compressed so that the weight of the wearer is not transmitted to the ground. The midsole-side preventive projection member absorbs the primary shock that occurs first, and the midsole-side preventive projection member is inflated again in the compressed state, and the secondary shock and surplus energy generated by the secondary are beneficially returned. It relates to a side tunnel projection shoe sole.

In general, the movement of the foot on the ground during walking is a three-step process, in which the left and right feet repeat the landing step by the heel, the center moving step from the heel to the heel, and the step of the heel pushing off the ground. In conventional shoes, the shape of the heel is almost perpendicular to the ground, and in the case of shoes, a sharp edge is formed on the heel so that the edge touches the ground first during the landing stage. Because of its shape, the impact at the time of landing is large, and the movement to the center movement stage, which is the next stage of landing, is performed at once, so that a sudden impact force is transmitted to each joint of the leg and body as well as the ankle joint, resulting in poor landing feeling and poor walking. Naturally.

Conventional tunnel protrusion type shoe sole is not formed with an insertion groove in the upper pad and the insertion groove side edge jaw is not formed on both sides of the insertion groove, and between the lower portion of the upper support protrusion and the upper portion of the lower support protrusion. Since the cushion space part of the oval shape is not formed, the thickness of the shoe sole is heavy, the weight of the shoe sole is heavy, and it is inconvenient to wear, and it is unstable and unstable posture to maintain the safety accident caused by wearing shoes. There was this.

Conventional tunnel protrusion type shoe sole has a problem that the lower portion of the upper support protrusion and the upper portion of the lower support protrusion cannot maintain the center of the support protrusion in a constant state, and the cushion movement of the up and down direction is operated at the correct position. There is a problem that can not be, when the landing of the shoe sole has a problem that the center of the support protrusion is broken or broken when the cushion movement in the vertical direction for a long time due to the strong landing force.

Conventional tunnel protrusion-shaped shoe sole is when the lower pad is coupled to the lower portion of the upper pad, an elliptical cushion space portion is not formed between the lower portion of the upper support protrusion and the upper portion of the lower support protrusion, and before and after the landing of the shoe sole. Since the lower part of the upper support protrusion and the upper part of the lower support protrusion are always bonded, the cushion and the repulsive force are weak and the lower part of the upper support protrusion and the upper part of the lower support protrusion are bonded to each other with adhesive. Repulsive force is weak and there is a weak buffer effect.

The conventional through tunnel protrusion type shoe sole has no insertion groove formed at both sides of the rear side edge of the upper pad, and the insertion groove side edge jaw is not formed at both sides of the insertion groove from one side to the other side. The penetrating through tunnel is formed, and if it is worn for a long time, the rain water penetrates between the penetrating tunnel, the shoe itself is extremely heavy and uncomfortable when worn, and there is a problem that foreign matter is inserted between the through tunnel and becomes dirty and dirty.

The upper midsole-type shoe sole combined with the conventional auxiliary midsole has no insertion groove formed in the upper pad, and the side grooves of the insertion groove are not formed on both sides of the insertion groove, and the lower portion and the lower support protrusion of the upper support protrusion. Since the cushion space of the oval shape is not formed between the upper parts of the shoe, the sole of the shoe is thick and the weight of the shoe is heavy, and it is inconvenient to wear. There was a problem that an accident occurred.

The present invention is to improve the problem that appears in a conventional shoe sole, a support protrusion is formed in the midsole and a tunnel is formed between the support protrusion is landed on the ground at the bottom surface of the sole of the shoe sole and flat slip form The purpose is to provide a shoe sole that can achieve the effect of forming a feeling of walking on the sand barefoot.

The shoe sole of the present invention has a support protrusion formed in the midsole, and a tunnel is formed between the support protrusions so that when the shoe is worn from the heel while the shoe is worn, the support protrusion and the tunnel are expanded and restored in the restored state when the sole is inflated. Because the part landing on the ground forms a flat slip shape with the ground, the impact amount due to the landing of the sole surface of the shoe is relatively reduced, and the support protrusion and the tunnel are contracted in parallel with the ground, resulting in high cushioning efficiency and smooth landing. The midsole, with its supporting protrusions and tunnels, cuts the impact hardness in half and doubles the cushioning effect.

When the shoe sole of the present invention wears shoes, the midsole side preventing protrusion member is primarily generated so that the weight of the wearer is not transmitted to the ground while the midsole side preventing protrusion member is pressed when the wearer's weight is loaded on the auxiliary midsole. It is a system that absorbs the shock and returns the secondary shock and surplus energy generated by the second solely as the midsole-side preventive protrusion member is compressed again, and it returns cushioning and repulsion force in preparation for the conventional shoe sole. It is increased by 2 to 4 times and reduces the impact hardness by the increased cushion and repulsive force in half and increases the cushioning effect by the increased cushion and repulsive force by 2 to 4 times or more.

In addition, the shoe sole of the present invention has a support protrusion formed on the midsole, and a tunnel is formed between the support protrusions, so the midsole is compressed, so that the part landed on the ground at the bottom of the shoe sole forms a flat slip shape with the ground. Soft and natural gait is achieved without sudden impact on joints, legs and joints of the body, and repulsion occurs when the bottom surface of the sole is out of the ground and the support protrusion and tunnel of the midsole contracted in the previous step are restored. And the pedestrian's foot is pushed in the direction of progress, the walking efficiency is high, light and light walking is possible, and the effect of walking on the sand with bare feet can be obtained.

The present invention is coupled to the lower part of the upper and consists of a midsole and an outsole, and the sole surface is formed in an arc shape in which the bottom surface is convex downward from the front portion to the rear portion, and the bottom surface is hooked from the front portion to the rear portion. Midsole consisting of a midsole side preventive projection member 30 is formed in an arc-shaped convex shape in the lower direction, coupled between the midsole front member 22, the midsole rear member 24 and the midsole front member 22 ( 20); It is coupled to the rear of the midsole front member 22, 1 to 10 side preventing projections 36 are formed between the upper plate 32 and the lower plate 34, and the side through tunnel between the side preventing projections 36 ( A midsole-side preventive projection member (30) formed with 38); Auxiliary midsole 40 is coupled to the upper portion of the midsole side preventive projection member 30; And is coupled to the lower portion of the midsole 20, the side surface is characterized in that the bottom surface is composed of an outsole 10 made of a convex shape convex downward from the front portion to the rear portion so as to be masai walking It relates to a side tunnel projection shoe sole formed with a support projection and a side through tunnel.

The present invention is coupled to the lower part of the upper and consists of a midsole and an outsole, and the sole surface is formed in an arc shape in which the bottom surface is convex downward from the front portion to the rear portion, and the bottom surface is hooked from the front portion to the rear portion. A midsole 20 formed of a convex arc shape convex in a downward direction and composed of a midsole side preventing protrusion member 30 coupled to the rear of the midsole front member 22; It is coupled across the rear of the midsole front member 22, and 3 to 40 side preventive projections 36 are formed between the upper plate 32 and the lower plate 34, and are laterally disposed between the side preventive projections 36. A midsole-side preventive projection member 30 having a through tunnel 38 formed therein; Auxiliary midsole 40 is coupled to the upper portion of the midsole side preventive projection member 30; And a side preventive projection and a side through tunnel, which are coupled to the lower part of the midsole 20 and have an outsole 10 formed in an arc shape convex in a downward direction from the front part to the rear part. It relates to a formed side tunnel projection shoe sole.

The shoe sole of the present invention is to manufacture the midsole side preventive projection member 30 separately to combine the midsole side preventive projection member 30 coupled to the rear of the midsole front member 22. In the shoe sole of the present invention, the midsole 20 is preferably manufactured by combining the midsole front member 22 and the midsole side preventing projection member 30 with an adhesive.

The shoe sole of the present invention, when the wearer wears shoes when the weight of the wearer is loaded on the auxiliary midsole 40, the midsole side preventing protrusion member 30 is compressed so that the weight of the wearer is not transmitted to the ground. 1) absorbs the primary shock that occurs first, the midsole side preventive projection member 30 is made of a system that returns the secondary impact and surplus energy beneficially returned as it expands again in a compressed state.

In the present invention, the midsole side preventive projection member 30 has a plurality of lateral through tunnels 38 penetrated in one form from one side to another, such as a seagull, mulberry, triangular prism, square prism, cylindrical or elliptic prism. ) Is formed, between the lateral through tunnel 38 and the lateral through tunnel 38, the side preventive projection 36 formed in the form of gull, mulberry, triangular prism, square pillar, cylindrical or elliptic cylinder. Many are formed.

In the present invention, when the midsole side preventive projection member 30 is formed at the rear portion of the midsole as shown in Figs. 1 to 6, preferably, 1 to 10 side preventive protrusions 36 are formed, and the front of the midsole. In the case where the portion is formed across the rear portion, preferably 3 to 40 side blocking projections 36 are formed. The shoe sole of the present invention has a plurality of side through tunnels 38 formed in a seagull form from one side to the other side and between the side through tunnel 38 and side through tunnel 38, seagull, mulberry type. Since the triangular prism shape, the square pillar shape, the cylindrical shape or the ellipsoidal shape of the side prevention projections 36 formed in plural, there is an effect of increasing the elasticity and restoring force of the sole by 2 to 3 times.

In the present invention as shown in Figures 1 to 6 the number of side preventive projections can be formed from a stable support form from one when formed in the rear portion of the midsole, if the number of support projections 10 or more tunnel spacing Narrow problems arise from the cushioning and repulsive force caused by the support protrusion. In the present invention, the number of the side preventive protrusions may form a stable support form from three when the number of the side protrusions is formed from the front part to the rear part of the midsole, and when the number of the supporting protrusions is 40 or more, the tunnel interval is narrowed. The problem of weak cushioning and repulsive force caused by projections is generated.

In the shoe sole of the present invention, since the cushioning and repulsion force are acted while the side prevention projections 36 formed in the shape of a seagull are pressed at the moment of landing of the shoe sole, the cushion and repulsion force are increased by 2 to 4 times or more as compared to the conventional shoe sole. The impact hardness caused by the cushion and the repulsive force is reduced by half, and the cushioning effect by the increased cushion and the repulsive force is increased by 2 to 4 times.

In the case of the foot wearing the shoe sole of the present invention, the movement of the foot with respect to the ground during walking can be observed by being divided into a landing stage, a center movement stage, and a departure stage. The shoe sole of the present invention forms a slip shape that is flat on the ground at the bottom surface of the shoe sole in the restored state after the side preventive projection 36 is compressed and restored after the side preventive projection 36 is compressed. Therefore, the amount of impact due to the landing of the sole surface of the shoe is relatively reduced, and the side prevention projection is contracted in parallel with the ground, resulting in high buffering efficiency, smooth landing, and weight distribution. The midsole of the present invention can obtain the effect of dispersing the weight to reduce the impact hardness in half and increase the buffering effect by more than 2 times in case the support protrusion and the tunnel is not formed.

In the shoe sole of the present invention, when the heel touches the ground at the landing stage, the ground area of the sole is wide at the moment the heel touches the ground, so that the amount of impact due to landing is relatively reduced and the side prevention projections 36 are parallel to the ground. As it contracts in posture, it has high cushioning efficiency and smooth landing, and reduces the impact hardness by half and increases the buffering effect more than twice. The shoe sole of the present invention has a side support projection 36 formed in the midsole, and since the through tunnel is formed between the side prevention projection 36 and the side prevention projection 36, the soft support protrusion ground when the shoe sole is landed. It can be placed in parallel with the state to increase the buffering efficiency due to shrinkage, and during the landing and center movement stage, the support protrusion is reconstructed in the detachment stage to generate a repulsive force, thereby improving the walking efficiency and weight distribution. In addition, the shoe sole of the present invention is compressed by the support protrusion when the walking movement is connected to the center movement step, so that the part landing on the ground from the bottom surface of the shoe sole forms a flat slip shape with the ground, according to the landing of the sole surface of the sole Since the impact amount is relatively reduced and the support protrusion is contracted in parallel with the ground, a high cushioning efficiency and a soft landing are achieved, and the impact force is continuously dispersed and absorbed, and the weight is dispersed.

In addition, the shoe sole of the present invention does not cause a sudden impact on the ankle joint, the leg and each joint of the body because the site where the support protrusion is compressed to form a flat slip form with the ground from the bottom surface of the sole of the shoe A smooth and natural gait is achieved and the weight is distributed. In the shoe sole of the present invention, the bottom surface of the sole is out of the ground at the departure stage, the support protrusion, which was contracted at the landing stage, is restored, and the pedestrian's foot is pushed in the direction of progress so that the walking efficiency is high and the light and light walking is possible. This dispersion effect can be obtained.
