First, with reference to Figures 1 to 4 will be described a functional roll sole according to an embodiment of the present invention.

1 is an overall perspective view showing a functional rolled shoe sole according to an embodiment of the present invention, Figure 2 is an exploded perspective view of Figure 1, Figure 3 is a cross-sectional view of Figure 1, Figure 4 shows a separate cross-sectional view of FIG. will be.

As shown in Figures 1 to 4, the functional rolled shoe sole according to an embodiment of the present invention is a Masai Barefoot Technology (Masai Barefoot Technology) shoes that do not have a rear axle of the shoes and walking like a Masai, the bottom of the shoe (curved) In the hollow cushioning projection 130 is formed is a cushion window 100 and the sole 200 is coupled to the bottom surface of the cushion window 100 to form an arc shape of the curved surface convex from the heel portion to the front of the foot It is configured to include.

First, the cushion window 100 will be described.

The cushion window 100 is made of a soft synthetic resin material (eg, polyurethane foaming resin) having a low hardness and having a very low hardness, and having a low compressive strain, and the structure has a sole shape. The edge wall 120 protruding downward toward the outer circumference of the bottom of the window sheet part 110 is formed. At this time, the edge wall 120 is formed in the cushion window sheet portion 110 in a state in which the upper surface of the sole 200 to be described later is left to be bonded.

In addition, a partition 112 partitioned into a front space part and a rear space part protrudes downward in the horizontal direction in the middle of the bottom of the cushion window sheet part 110. An air flow passage 114 connecting the front and the rear is installed in the partition 112, and an intermediate check valve 114 a is installed in the air flow passage 114 to partition the air at the rear side of the partition 112. ) Only to the front side.

In addition, the front and rear of the cushion window seat 110 is formed in the front space side of the outsole 100 is formed in the inner outlet inlet 116 and the rear space portion side of the outsole 100 to allow air to flow. And an external outlet opening 118 through which air is distributed. The inner check inlet 116 is provided with a front check valve 116a to discharge the air in the front space side of the partition 112 to the front of the sole, and the outer check inlet 118 has a rear check valve 118a Installed to allow the outside air of the rear side of the cushion window sheet portion 110 partitioned by the partition wall 112 to flow into the rear space portion under the cushion window sheet portion 110 behind the partition wall 112.

As such, when the cushion window 100 is stepped on by the sole and the operation of lifting the foot is repeated, an air pumping action is active in the closed space formed between the lower portion of the cushion window 100 and the sole 200 to be described later. It is done.

And, the upper surface of the cushion window sheet portion 110 may be attached to the insole 140 is freely ventilated, such as a woven paper. The insole 140 is also provided with a through-hole 142 through which air can be distributed.

Next, the hollow cushion protrusion 130 will be described.

As shown, the hollow cushion protrusion 130 is formed to protrude downward on the bottom surface of the cushion window sheet portion 110, the hollow interior having an opening 132, one end or both ends of which are open, and an empty space is formed. When the air contained in the sealed air pressure is generated by the compression deformation caused by the external force. Since the hollow cushion protrusion 130 is also made of a rubber material having elasticity according to contraction and restoration to some extent, such as the cushion window 100, the shock transmitted through the sole of the user is the hollow inside of the hollow cushion protrusion 130. The air enclosed in the air is compressed and then restored to help to alleviate the impact, which allows it to act as a midsole. In addition, since the empty space is formed between the plurality of hollow cushion protrusions 130, the weight of the sole can be reduced.

And as the hollow cushion projections 130 are formed at regular intervals between the air cushion between the hollow cushion projections 130 is to be formed.

The opening 132 of the hollow cushion protrusion 130 is attached to the upper surface of the sole 100 to be described later to be closed so that the air is sealed in the hollow inside of the hollow cushion protrusion 130 (134) (hereinafter, The hollow interior formed by sealing the opening 132 of the hollow cushion protrusion 130 may be referred to as an 'air chamber'.

As such, when the air chamber 134 is formed in the hollow of the hollow cushion protrusion 130, each of the hollow cushion protrusions 130 is elastically compressed in the air chamber 134 like a rubber ball, thereby acting as an air cushion. The shock absorption effect is excellent. Therefore, the cushion window 100 is returned to its original position by the restoring force of the hollow cushion protrusion 130 itself, in which the air compressed in the air chamber 134 is instantaneously restored, thereby providing a very soft and rhythmic grounding to the sole. Will be.

Next, the sole 200 will be described.

2 and 3, the sole 200 is formed in the shape of a convex curved convex from the heel to the front of the foot, is formed so that the inclination angle of the heel is 25 to 50 °. MBT shoes. In addition, the bottom window 200 is provided with an upper jaw 210 to be bonded to the outer circumference of the cushion window sheet portion 110 to the upper surface, the inner side of the upper jaw 210 to the cushion window 100 A groove 220 that can accommodate the formed partition wall 112, the edge jaw 120, and the hollow cushion protrusion 130 is formed.

Here, the sole 200 is made of any one selected from polyester or polyurethane having a hardness of 40 to 60. Here, when the hardness of the sole 200 is 40 or less, the soft sole does not function as a support, and when the hardness of the sole 200 is 60 or more, the sole 200 acts as an elastic body. There is a problem that can not be. In addition, the non-slip window 230 having excellent abrasion resistance is attached to the entire bottom surface of the sole 200 by forming a non-foamed layer having a rubber series or elasticity that is stronger and stronger than the sole 200. Can be installed.

Functional rolled sole provided as described above acts as follows.

By the air chamber 134 formed in the hollow cushioning projection 130 of the cushion window 100 during the landing and the center movement step by the wearer's walking, as if the rubber ball always maintains a firm elasticity At the same time, the initial impact force is more attenuated by the sole 200. In addition, since the shapes of the hollow cushion protrusion 130 and the sole 200 of the retracted cushion window 100 at the step of restoring are simultaneously restored, the repulsive force is added to increase the walking efficiency more than conventional MBT shoes. .

In addition, whenever the foot lands on the ground, the cushion window 100 circulates a large amount of air sequentially from the front to the back. That is, when the rear side of the cushion window 100 is pressed by the foot rear axle, the air filled in the rear space portion is temporarily installed in the rear space portion while the rear space portion formed on the rear side of the partition wall 112 is temporarily installed. As the air flows out through the intermediate check valve 114a through the flow passage 114 and flows into the front space corresponding to the front part of the sole, the amount of air filled with the air volume of the front space is filled in front of the internal outlet opening 116. It is forced to discharge into the upper shoe through the check valve 116a.

Subsequently, when the front side of the cushion window 100 is pressed by the front part of the sole, which is the next operation, the air filled in the front space part while being contracted by the lower front space part is installed in the front space part of the cushion window 100. Through the front check valve (116a) to be discharged to the front of the sole to ventilate the front part of the sole is sweaty and humid much cold. In addition, when the front part of the sole of the sole is pressed the front side of the cushion window 100, the heel of the foot is lifted up, the cushion window 100 of the rear side that was compressed by stepping on the heel of the foot is expanded at the same time as the foot heel is lifted, The rear check valve 118a installed at the outer outlet opening 118 of the cushion window 100 sucks the outside air into the rear space so that the air is filled in the rear space, and is then discharged to the front of the sole in the next operation. .

Since the three forward and backward check valves 114a, 116a, and 118a described above are to flow air only in one direction, the air in the rear space portion is moved to the front space portion as described above, and the air in the front space portion is It moves to the front of the sole, and the outside air toward the rear of the foot is only introduced into the rear space. That is, whenever the sole lands on the ground, a large amount of air can be circulated sequentially from the front to the back.

Figure 5 is a perspective view showing a functional rolled shoe sole further provided with a transparent member according to another embodiment of the present invention, Figure 6 is a cross-sectional view of the functional rolled shoe sole is a transparent hose according to the present invention, Figure 7 is the present invention The cross-sectional view of the functional rolled sole is provided with a transparent member in the form of a transparent plate.

The transparent member 300 is provided in the form of a transparent hose 310 or a transparent plate 320 to apply a color to the surface of the hollow cushion projection 130 of the cushion window 100 to be described later transparent hose 310 B can be increased by making the inside visible through the transparent plate 320.

As shown in FIG. 6, the transparent hose 310 seals the air in the space at atmospheric pressure. When the external hose is compressed, the sealed space is compressed, and the air pressure inside the transparent hose 310 is compressed. Generated to absorb shocks.

As illustrated in FIG. 7, the transparent plate 320 may convex a surface to make the hollow cushion protrusions 130 more enlarged, thereby making the inside of the sole 100 visible. .

The transparent hose 310 or the material of the transparent plate 320 may be selected as a material having excellent transparency, restoring force, tensile force, cold resistance, etc., but may be generally made of a polyurethane resin.

8 is a cross-sectional view of a functional rolled sole according to another embodiment of the present invention, Figure 9 is an exploded cross-sectional view of FIG.

As shown in FIG. 8, this embodiment is generally similar to the embodiment described based on FIGS. 1 to 4, but the hollow cushion protrusion 130 of the cushion window 100 is turned upside down so that the upper window 200 is visible. It is characterized in that coupled to, the non-breathable plate 400 is configured to be further coupled to the upper side of the cushion window 100 will be described only for the other parts and description of the same parts will be omitted.

The cushion window 100 is formed with a border portion 120 protruding upward from the outer circumference of the upper surface of the cushion window sheet portion 110 having a sole shape, and is located in an inner space surrounded by the edge portion 120. The plurality of hollow cushion protrusions 130 protrude upward at a predetermined interval so as to have an arc-shaped convex shape.

In addition, the partition wall 112 partitioned into the front space portion and the rear space portion in the inner space of the cushion window sheet portion 110 is formed to protrude upward in the lateral direction. An air flow passage 114 connecting the front space portion and the rear space portion is formed in the partition 112, and the air flow passage 114 has an intermediate check valve for moving only the air in the rear space portion to the front space portion. 114a is provided.

The non-breathable plate 400 is prepared in advance to be processed, it may be formed of a soft synthetic resin material having a higher hardness than the cushion window 100, the tensile strength and cold resistance. For example, it may be formed of a foamed expanded material or a non-foamed polyurethane resin material composed of a pre-processed EVA base compound. In addition, the non-breathable plate 400 is provided with a non-breathable material that does not pass through the air is coupled to the upper side of the cushion window 100 is provided in the shape of an arc shape concave in the middle so as to seal the space therebetween.

In addition, the non-breathable plate 400 has an inner outlet opening 416 formed on one side of the front side to allow air to flow through an upper side of the front space portion of the cushion window sheet 110, and an external outlet opening on the rear side of the non-breathable sheet 400. 418 is penetrated to allow air to flow through the upper portion of the rear space of the cushion window sheet 110. In this case, the inner check inlet 416 and the outer check inlet 418 are provided with a front check valve 416a and a rear check valve 418a, respectively.

Functional roll sole according to the present embodiment provided as described above acts as follows.

By covering the non-breathable plate 400 with the upper surface of the cushion window 100 is coupled to the interior of the cushion window 100 to be a closed space.

At this time, when the shoe sole receives an external force, the non-breathable plate 400 descends to compress the hollow cushion protrusions 130 of the cushion window 100 to absorb shock, and the unit area of the inner sealed space of the cushion window 100 is absorbed. As it is compressed, the unit area becomes narrower. At this time, the air staying in the space around the hollow cushion protrusions 130 is forced out through the intermediate check valve 114a and the front check valve 416a to the shoe inner space or the outside of the space, and was compressed when the external force is released. As the hollow cushion protrusions 130 are restored to the original state at once, the unit area of the inner space is also restored, and the narrowed space area is increased, and the outside air is sucked in as much air as the inner space is increased through the rear check valve 418a.

In more detail, when the rear space part of the cushion window seat part 110 receives an external force, the air of the rear space part is installed on the air passage 114 of the partition 112 and the non-breathable plate 400. It is forcibly moved into the shoe through the front check valve 416a installed at the inner outlet inlet 416 of the rear, and the rear check valve 418a installed at the outer outlet inlet 418 of the non-breathable sheet 400 when the external force is released. Through the air inside the shoe is injected into the rear space. In addition, when the front space portion of the cushion window seat 110 receives an external force, the air of the front space portion is forcibly discharged into the shoe through the front check valve 416a installed at the inner outlet opening 416 of the non-breathable plate 400 When the external force is released, the air or the outside air of the rear space is injected into the front space through the middle check valve 114a of the partition 112 and refilled so that the air inside the shoe can be continuously circulated continuously.

As described above, the shoe equipped with the functional rolled sole according to the present invention as shown in FIGS. 1 to 9 is moved smoothly along the curved shape so that the ankle joint, the leg and each joint of the body are soft without causing a sudden impact. Natural walking is achieved.
