Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG.

In FIG. 1, the shoe 1 is provided with an insole 10 surrounding the foot and a sole 30 integrally coupled with the insole 10 and touching the bottom surface, and impacted between the insole 10 and the sole 30. Interposed midsole 20 is coupled to absorb the. The insole 10 may be formed of a structure that covers the heel including the heel, but may be a structure that traverses the top of the foot like slippers. The sole 30 may be flat to a certain thickness or may be different in various shapes, shapes, or heights.

The midsole 20 is positioned below the insole 10 and is approximately flat in shape. The midsole 20 may be rubber, synthetic resin, or the like as a material having elasticity, and in particular, polyurethane may be applied. The midsole 20 plane is interviewed with the bottom of the insole 10. The bottom surface of the midsole 20 is formed with a plurality of protrusions protruding. The bottom of the midsole 20 is divided into a front, a center, and a rear, and protrusions of different lengths are formed.

A plurality of first protrusions 21 having a predetermined height protrudes at a predetermined interval in front of the bottom of the midsole 20. In addition, a plurality of second protrusions 22 having a height smaller than that of the first protrusions 21 are formed between the first protrusions 21. The second protrusion 22 may have a smaller diameter than the second protrusion 22. The first protrusion 21 absorbs the primary shock when the sole 30 touches the ground, and the second protrusion 22 absorbs the secondary shock. In other words, after the first protrusion 21 absorbs the shock primarily, the second protrusion 22 may absorb the second protrusion when the first protrusion 21 is compressed and the shock is transmitted.

In addition, a plurality of third protrusions 23 having a predetermined height are protruded at regular intervals in the lower center of the midsole 20. In addition, a plurality of fourth protrusions 24 having a predetermined height protrude at regular intervals from the lower rear of the midsole 20. The length of the fourth protrusion 24 is the longest among the protrusions formed at the bottom of the midsole, and then the length of the fourth protrusion 24 is smaller in order of the first protrusion 21, the third protrusion 23, and the second protrusion 22. Projections formed to protrude below the midsole 20 are adapted to absorb shocks by varying the length depending on the weight applied to the sole when a person walks. In addition, the amount of impact absorption will also vary depending on the number of protrusions.

On the other hand, the upper portion of the sole 30 coupled to the protrusions formed on the bottom surface of the midsole 20 is formed with a plurality of receiving grooves and grooves.

A first accommodating groove 31 for accommodating the insole 10 is formed at the upper edge of the sole 30. The first accommodating groove 31 is a groove in which the insole 10 is inserted, and has a border shape surrounding the outer periphery of the bottom of the insole 10. Thus, a second accommodation groove 32 for receiving the midsole 20 is formed inside the first accommodation groove 31. The second accommodating groove 32 has a groove formed to the depth of the midsole 20 so that when the midsole 20 is accommodated in the second accommodating groove 32, the sole 30 and the midsole 20 have a flat surface. The bottom surface of the insole 10 is coupled in surface contact therewith. In addition, in the front of the second accommodation groove 32 of the sole 30, a third accommodation groove 33 for receiving the first projection 21 and the second projection 22 is formed, the third accommodation groove 33 ), The first groove 35 into which the first protrusion 21 is inserted is formed. Furthermore, the second projection 22 of the midsole 20 is in contact with the bottom surface of the second accommodation groove 32. Accordingly, the first protrusion 21 is inserted into the first recess 35, and the second protrusion 22 is in surface contact with the surface of the third accommodation recess 33. In addition, a second groove 36 for accommodating the third protrusion 23 is formed at the center of the second accommodation groove 32 of the sole 30. In addition, a fourth accommodation groove 34 for receiving the fourth protrusion 24 is formed at the rear of the second accommodation groove 32 of the sole 30. The fourth accommodation groove 34 is provided as a single groove to accommodate a plurality of fourth projections 24 formed in the midsole 20 at one time. The fourth protrusion 24 is formed to protrude from the convex portion 25 protruding from the bottom surface of the midsole 20, and the convex portion 25 is inserted into the fourth accommodation groove 34.

A plurality of third grooves 37 are formed in front of the first accommodating groove 31 of the sole 30 to form an air layer when combined with the insole 10.

In Figure 2, the shock-absorbing shoe of the present invention made of such a structure consists of a structure of the plurality of protrusions formed on the bottom of the midsole and the detailed structure of the receiving groove and groove formed on the top of the sole corresponding to the bottom of the midsole.

In FIG. 3, the fourth protrusion 24 of the midsole 20 is completely inserted into and sealed in the fourth accommodation groove 34 formed as a predetermined space of the sole 30. At this time, when the shoe wearer walks, the heel first touches the foot, and the fourth protrusion 24 of the midsole 20 accommodated in the fourth accommodation groove 34 of the sole 30 as a portion to which the body load is directly applied. The weight applied to the shock is absorbed and alleviated in the fourth protrusion 24. In addition, air pressure is applied to the space formed between the fourth protrusions 24 in the fourth accommodation groove 34. In addition, after the heel touches the ground, the center of the sole touches. At this time, the weight applied through the third protrusion 23 of the midsole 20 inserted into the second recess 36 of the sole 30 is absorbed. Since the third protrusion 23 typically has a small impact on the concave portion where the sole does not touch the ground, the third protrusion 23 may have a small length but a wide contact area.

In addition, a rather large load is applied to the front of the foot after the sole touches the ground. Since the front of the foot is the widest part of the sole, the second protrusion 22 and the first protrusion 21 inserted into the first recess 35 are in contact with the third receiving groove 33 of the sole 30. The load is distributed. Accordingly, the first protrusion 21 absorbs the primary shock on the direct load, and the second protrusion 22 absorbs the secondary shock on the load distributed after the impact is applied to the first protrusion 21. At the same time, additional support is provided.

And finally, the front of the sole, that is, the toe portion to the part which touches the ground so that the shock delivered to the sole by the air pressure formed in the third groove 37 to be absorbed.

Therefore, the shock-absorbing shoe structure of the present invention is a structure that can sufficiently support and absorb the corresponding impact amount according to the portion applied to the sole of the shoe when the wearer walks, and does not burden the joints such as the ankle or the knee. By making the foot comfortable even when walking for a long time, there is an advantage of improving the reliability of the shock-absorbing shoes.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone who has it will know it easily.
