The present invention relates to a spring-loaded Masai Walking (rolling shoe) mounting midsole professional, more specifically, the spring-loaded bag is built in the upper pad to preserve the original shape of the sole and shoes as well as the bending of the walking The present invention relates to a midsole for mounting a specialized walking shoe for Masai Walking, which has a high frequency of soles, and has a spring-loading effect that improves walking stability.

In Korean Patent No. 10-377822, the reference numerals are 1: shoe, 2: upper, 3: shoe sole, 10: insole, 12: midsole, and 13: outsole. Looking at Korean Patent No. 10-377822, Masai Walking's active rolling walking foorware: walking shoes that have no heel of the shoe and the sole of the shoe is curved like a Masai. 2 to 4 of Korean Patent No. 10-377822 shows a walking method as described below, and is described as "walking by Masai Walking."

The Korean Walking Association, the World Walking Association, the footwear industry, and the general consumer call shoes such as Masai Barefoot Technology shoes walking like the Maasai without the heel of the shoe and the sole of the shoe's sole. Books, newspapers, magazines and television broadcasts are referred to as Masai Walking Shoes or Masai Walking Shoes.

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 formed at a right angle to the ground, and in the case of shoes, a sharp edge is formed on the heel so that this edge touches the ground first during the landing stage. Because of its linear 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 walking. It becomes unnatural.

When using a spring loaded bag material having a hardness of 15 to 30 for a conventional shoe sole, such a soft sponge material is used since the spring loaded bag material having a hardness of 15 to 30 is made of a soft sponge (Soft Sponge, Soft Wedge, Masai spring loaded bag). Hydrolysis occurred in the wet or wet soil, so when wearing shoes in a wet place or rural paddy field, there was a problem that the spring-loaded bag fell tattered in less than one month. Because the shoes are made of soft sponges, water is absorbed and spring-loaded bags are tattered from the shoes when the absorbed sponges are pressed tens of thousands of times a day for more than one month continuously with the hoof applied to the weight of 60kg to 100kg. There was this. Furthermore, if you wear a shoe made of spring-loaded bag with a hardness of 15 to 30, and you run a marathon or run, you can bark the sponge with your hoof with a weight of 100 kg to 300 kg for a whole day and press it tens of thousands of times a day. There was a problem that the spring loaded bag was tattered. Particularly, it was presented to parents in the countryside as a filial piety shoe. In the case of wearing shoes made of spring-loaded bags with a hardness of 15 to 30 in rural paddy fields, the spring-loaded bags fell tattered in less than one month, so the shoe soles were repaired again. There was a problem of performing after-service (recall).

The present invention has been made to improve the problems seen in the above-described conventional shoes, spring mounting bag is built in the upper pad can be easily and simply produced a midsole for mounting the rolling motion rolling shoes with a spring built-in spring mounting bag inside As water or wet soil is not absorbed and hydrolysis does not occur due to the absorption of water, spring-loaded bags can be prevented from being damaged by hydrolysis. The purpose of the present invention is to provide a midsole for mounting a rolling shoe with a built-in spring which improves the stability of walking and improves the shape of the sole with high frequency.

In the present invention, the midsole has a plurality of slits in which the front part is opened to the front end at a predetermined position of the front in the front of the insole, insole, insole, convex curved midsole with high elastic shank and convex curved outsole. A high-elastic shank 29 is formed in the upper portion of the upper waist portion in which the rib 29b is formed in the front and rear directions to form a portion 29a and is divided into several parts. The upper pad 110 is formed of a polyurethane having a hardness of 50 to 70, and has a spring-loaded bag 300 having an elliptical shape having a convex curved surface with respect to the ground. A lower pad 120 covering the spring-loaded bag 300 of the upper pad 110 from the bottom; The upper pad 110 and the lower pad 120 relates to a spring-loaded professional massaging walking shoe mounting midsole, characterized in that the finished product of the midsole is formed in a bonded state using an adhesive.

Spring mounting bag 300 is a symmetrical form in the midsole for mounting a professional shoe for walking shoes of the present invention, the upper and lower one to fix the coil springs on the inner side of the upper and lower pads 1 to 10 The upper pad 310 and the lower pad 320 having ˜10 spring fixing protrusions 312 and 322 formed therebetween and having 1 to 10 high frequency adhesive support rods 314 formed therebetween. ; A coil spring 330 fixed to the spring fixing protrusions 312 and 322 of the upper and lower pads 320; The high frequency adhesive side surface 316 of the upper pad 310 is in contact with the lower pad 320 in a state of high frequency adhesive treatment to wrap the outside of the upper pad 310 and the lower pad 320 to fill air therein. Characterized in that it consists of an outer air cover to form an air vacancy.

Masai walking professional rolling shoes equipped with a midsole of the present invention is a normal shoe composed of an upper 10, an outsole and an insole, and the sole of the shoe consists of an insole 21, a midsole 22 and an outsole 24, and Masai Barefoot Technology shoes, Masai Walking special shoes or Masai walking specialty shoes that do not have a rear axle and walk like a Masai with curved soles. In the shoe of the present invention, as shown in Figure 4, the rear axle of the outsole 24 is formed in an inclined curved shape of the main inclination angle of the shoe heel to the ground 5 to 40 degrees, the main inclination angle is less than 5 degrees Masai walking professional rolling shoes If the action is not achieved and the main inclination angle is more than 40 degrees, the inclination may be too steep, resulting in an unstable and unstable posture when wearing shoes or standing.

3 to 8, the heel of the midsole is equipped with a spring-loaded bag 300 according to the inclined curved shape as shown in FIGS. In addition, when the spring-loaded bag is built from the heel portion of the midsole to the fore-knee portion, it is preferable that a plurality of spring-loaded bags are formed in a plurality of forms. As can be seen in Figures 3 to 8, the massaging professional walking shoe equipped with the midsole of the present invention, in order to manufacture the finished product of the midsole 22, first, the upper pad 110 made of polyurethane having a hardness of 50 to 70. After the lower pad 120 is manufactured separately and the upper pad 110 and the lower pad 120 are in contact with each other in a position corresponding to the lower pad 120 at the edge of the spring mounting bag 300 of the upper pad 110. ) To produce the finished product of the midsole 22 in a state in which the spring-loaded back of the midsole is formed and then mounted inside the shoe. When the hardness of the midsole (22) is 50 or less in the Masai walking professional rolling shoes equipped with the midsole of the present invention, the midsole does not act as a support, and when the hardness of the midsole (22) is 70 or more, the midsole acts as an elastomer. There is a problem that can not.

Rolling shoes equipped with a midsole of the present invention can increase elasticity and resilience by embedding the spring-loaded bag 300 in the interior of the upper pad 110, as can be seen in Figures 3 to 8. If the hardness of the spring-loaded bag 300 is less than 15 so soft that the spring-loaded bag does not act as a support, and if the hardness of the spring-loaded bag 300 is 30 or more, there is a problem that the spring-loaded bag does not act as an elastic body.

In the spring-loaded rolling shoe mounting midsole of the present invention, the spring-loaded bag may be formed on the heel portion of the shoe and may be formed on the heel portion of the shoe from the heel portion of the shoe, and is selected from the heel portion of the shoe to the heel portion. Spring-loaded bags can be formed at either site. As can be seen in Figures 3 to 8 in the midsole of the present invention, the upper pad 110 is an elliptical spring mounting bag 300 of the main inclination angle of the heel is formed 5 to 40 degrees heel to the ground Formed. The spring-loaded bag embedded in the midsole of the present invention reduces the elastic hardness in half and increases the buffering effect in comparison with the case where the spring-loaded bag is not built.

The midsole of the present invention has a built-in spring-loaded bag 300 so that the spring-loaded bag 300 is placed in parallel with the ground when landing in contact with the lower pad 120 to increase the buffering efficiency due to shrinkage. The spring-loaded bag contracted during the landing and centering stages increases the walking efficiency because the shape is restored during the detachment stage and generates a repulsive force. In the spring movement bag mounting midsole for mounting a rolling shoe of the spring mounting bag of the present invention, the spring mounting bag of the midsole is manufactured in a state in which the upper pad 110 and the lower pad 120 are in close contact or the upper pad 110 and the lower pad ( 120 may be manufactured in a bonded form using an adhesive.

The spring-loaded bag 300 mounted on the shoe of the present invention is wrapped in a synthetic resin and does not have a separate work process for manufacturing an air cover and does not have a separate work process for installing a relaxation prevention wire inside the spring. In the process of combining the upper pad 310 and the lower pad 320 to form the air cover, the air cover and the high frequency adhesive support rod are formed by the high frequency bonding method to shorten the manufacturing process, and the air cover itself is torn or air leaks. It relates to a shock-absorbing functional well-being shoes buffer solved. The spring-loaded bag 300 mounted on the shoe of the present invention can effectively absorb the shock applied to the bottom of the shoe as a shock-absorbing shock absorber, thereby improving the wearing comfort of the shoe and protecting the knee or joint of the shoe wearer. Even if the shoes equipped with the relief device are used for a long period of time, the mounted spring 330 does not break or be damaged, and it is shocked by injection pylon (PHYLON) without producing by high frequency bonding or bond bonding. Midsoles and shock-absorbing shoes equipped with cushioning shock absorbers can be manufactured.

In the present invention, the midsole 22 is formed in the shape of a plate, modeling the shape of the sole and the surface of the sole, and a high elastic shank 29 is built in the upper inside of the midsole 22, so that the bottom surface of the heel of the sole According to the shape of the heel and the motion trajectory of the heel relative to the ankle joint during walking, the rolling motion is performed with respect to the ground during walking by forming a curved shape in front and rear directions. The high-elastic shank (29) embedded in the midsole of the present invention is divided into several parts by forming a plurality of slits (29a) in which the front portion is opened to the front end at a certain position in front of the front portion for reinforcement in the central waist portion A bead-shaped rib 29b is formed in the front-back direction, and the bottom surface of the heel of the sole is formed in a curved shape in the front-back direction according to the shape of the heel and the motion trajectory of the heel relative to the ankle joint during walking. The spring-loaded bag is built according to the curved shape inclined to the rear axle of the sole so that the rolling motion is performed.

As can be seen in Figures 3 to 8 in the midsole 22 is equipped with a midsole of the present invention, the midsole 22 is inserted into a shank (29) of a high elastic material therein, which preserves the sole of the sole and shoes and walks When the sole with high deformation frequency of flexion and elongation is restored to its original shape smoothly, it improves the stability of walking when walking and the repulsive force is added at the departure stage to promote light walking. In the rolling shoe equipped with the midsole of the present invention, the shank 29 may be formed in any shape and material. However, the shape of the plate is formed using a PVC material, which is modeled after the outer shape and curved surface of the midsole 22. The front portion of the shank 29, which is preferably formed with a relatively large bending angle during walking, forms a plurality of slits 29a open to the front end at a predetermined position in front of the shank, thereby dividing it into equal parts. Of the midsole 22 by forming a plurality of through-holes 29c by forming a bead-shaped rib 29b in the front-rear direction for easy reinforcement and the center waist portion of the shank 29 for reinforcement. It is formed so that the molding liquid can flow smoothly during manufacturing.

Rolling shoes equipped with a midsole of the present invention can observe the movement of the foot on the ground is divided into a landing stage, a center movement stage and a departure phase when walking. Rolling shoes equipped with the midsole of the present invention is the grounding area of the outsole to the ground at the moment of landing in the landing stage, because the grounding area of the sole is relatively reduced the amount of impact due to landing and the spring-loaded back shrinks in parallel with the ground, cushioning efficiency This high, smooth landing is achieved, and the midsole with spring loaded bag reduces the hardness by half and increases the cushioning effect in case the spring loaded bag is not formed. Rolling shoes equipped with a midsole of the present invention, when the walking motion is connected to the center movement step, the bottom surface of the curved rear axial rolls along the ground and the impact force is continuously absorbed and absorbed. In addition, since the center of the rolling shoe is equipped with a midsole of the present invention is gradually moved along the curved shape, the ankle joint, the leg and each joint of the body does not cause a sudden impact and smooth and natural walking. Rolling shoes equipped with the midsole of the present invention is the heel of the sole out of the ground at the step of leaving the spring-loaded back that was retracted in the previous step as the resilience occurs and pushes the foot of the pedestrian in the direction of progress, the walking efficiency is high and only It is possible to walk lightly.

In the rolling shoe equipped with the midsole of the present invention, the sole of the sole and the shoe are well preserved by the shank 29 inserted into the midsole 22, and the frequency of the sole which is deformed in flexion and extension during walking is high. Restoration to the original shape is smooth and the shape of the sole is elastic and firm, so the walking stability is high and the repulsive force is added by the restoring force at the step of release, pushing the front gum in the direction of walking, making walking lighter and more efficient. This is high.

According to the present invention, the spring-loaded bag is built in, so that the spring-loaded rolling movement can be easily and simply manufactured. The hydrolysis by the absorption of water without absorbing water or soil with water inside the spring-loaded bag is possible. It is possible to prevent the spring-loaded bag from being damaged by hydrolysis as it does not occur, thus preserving the original shape of the sole and shoes, and excellent in restoring the shape of the sole with high frequency of bending during walking and improving the stability of walking. It is very useful in the shoe industry.
