 FUNCTIONAL SHOES WHICH IS ROLLING MOVEMENT FOR RARE FOOT WALKING}

 The present invention relates to a functional shoe, and more specifically, the movement of the cloud according to the seesaw principle of the cloud body along the path of movement of the ground reaction force during walking to enable walking in the form most similar to barefoot walking to the human body The present invention relates to a functional shoe in which a cloud movement of barefoot walking is performed to allow proper walking.

In general, if a person weighing about 60kg walks at an average of 6000 steps per day, the foot will have a load of about 432 tons, which is more than the weight of the jumbo for international flights (about 400 tons), which is transmitted through the soles by walking. How to distribute the load according to the walking method is a factor directly to the health of the foot or human body.

There are 26 large and small bones on the foot, which are supported by ligaments and muscles, and the most ideal gait allows the human body to live a healthy life by maximally protecting the ligaments and gait. Its value is determined by how it is assigned.

Various types of functional shoes have been developed in order to impart the function of shoes for the most ideal walking, and will continue to be developed in the future.

As a sample study for this ideal gait, the African Maasai barefoot walking method is most widely known to the general public, and various numerical data are supported by experiments. There are two characteristics of the Maasai barefoot walking method, one of which is to increase the stride length to make full use of the muscles and skeletons that make up the foot. In other words, if the stride length is increased, the entire sole of the foot must be moved to support the weight, which leads to correct motion. Secondly, another advantage of the Masai's pedestrian nature is walking barefoot barefoot. This is the most suitable form of the human body given in the beginning, and since there is no external fixation (shoes, etc.) from the ankle to the sole of the ankle, sufficient internal movement of the foot is possible. It becomes possible.

Therefore, shoes having a primary function of protecting the foot from external foreign matters are faithful to the basic purpose, but there is a fundamental problem that it is impossible to faithfully walk because it is a factor that suppresses possible internal movement in bare feet.

In order to solve this problem, various functional shoes have been developed that are suitable for barefoot walking, and are still under development. However, there is a problem that none of the existing functional shoes satisfy the shock absorbing function applied to the foot at the same time while faithfully performing the internal movement that occurs naturally by barefoot walking.

 The present invention has been made in order to solve the above problems, the purpose of providing a functional shoe to enable the internal movement in the barefoot walking by the rolling body made of natural rolling motion in accordance with the pressure applied through the sole have.

In order to achieve the above object, a shoe according to an embodiment of the present invention, the shoe, the sole which forms the outer surface bottom; An insole positioned above the sole and in contact with the bottom of the sole; Concave groove formed on one surface of the sole or insole; And formed on the sole or insole surface of the corresponding position where the concave groove is formed, the cloud body made of a smaller size than the recess; It is a technical feature to provide a functional shoe in which the rolling motion is made in the concave groove by the rolling body according to the pressure applied to it.

And, preferably, the rolling body is located on the path of the ground heel center, the center of heel and the ground reaction center leading to the front portion, which is the order of the ground reaction on the sole of the foot while walking, the ground reaction center point is moved It should be located at the site corresponding to the focal point on the path. In addition, the sole surface is to be made of a spherical shape protruding on one side of the injection molding surrounding the bottom heel of the insole in contact.

In addition, the cloud body is located on at least two or more points of the outside of the heel, the center of the foot, and the front portion on the path of the ground reaction center point, and the ground reaction center point on the bottom of the insole that the sole surface is in contact An injection molding is attached to the movement path and a spherical cloud body protruding from the injection molding is positioned.

 As described above, the present invention has the effect of making walking more accurate as well as walking more comfortably, as well as more comfortable walking by the cloud body.

 Hereinafter, with reference to the drawings showing a functional shoe made of the inner motion of the barefoot walking according to the present invention having the above characteristics will be described in more detail.

1 is a plan view showing the tracheal trajectory of the foot according to the normal walking. As shown, in the normal case of the pedestrian posture, the foot center line a walks on the sole 10 in a toe out position rotated by 7 ° outward with respect to the traveling direction b.

The range of toe out, which is considered to be normal walking, is when the center of gravity line a is rotated outward by 0 to 10 ° with respect to the direction of travel. When the foot is viewed from above, when the foot is viewed from above, the front part of the foot is rotated about 7 ° out of the body to perform the rolling motion in contact with the ground. . Since the ground reaction center point is moved to the inside of the sole surface 10, the ground reaction center point is moved along the foot center line a.

2 is a plan view showing a path along which the ground reaction center point moves on the sole. As shown, the movement trajectory 20 of the most ideal ground reaction center point when viewed with respect to the center of gravity line (a) touches the floor from the outside of the heel and moves in a straight line in the middle part, which is the center point P of the sole 10. Afterwards, the center of ground reaction force moves to the second toe in a curved line. For example, in the case of a non-O-shaped leg, the movement trace 30 of the ground reaction center point appears when walking, and in the case of an X-shaped bridge, the movement trace 40 of the ground reaction center point during walking is Appear inward.

Therefore, it is preferable to walk along the movement trajectory 20 of the normal ground reaction as described above, and the greatest feature of the present invention for achieving this is that the force of the sole applied when walking is naturally distributed according to the trajectory of the ground reaction force 20. It is to be possible. To do this, the main point is to arrange the cloud body at the position that forms the trajectory of the ground reaction force of the sole of the shoe and the insole so that the cloud movement can be performed according to the movement trajectory. Hereinafter, each embodiment will be described in detail.

3 is a view according to an embodiment of the present invention. As shown, the present invention is provided with a cloud body 200 protruding in the area corresponding to the center point (P) of the sole surface shown in Figure 2 in order to allow the force to be transmitted according to the movement trajectory of the ground reaction force . The cloud 200 is made of a ball shape and made of a relatively hard material, and forms a shape that is attached to the bottom of the insole 110 forming the inner window of the shoe (100). In addition, such a ball is not formed at the same time as the soft insole 110 and made of a separate process.

Preferably, the cloud 200 is attached to the injection molding 210 that extends from the heel of the insole 110 to the concave portion of the sole through the center point P and is integrally formed. Therefore, the injection molding 210 has the advantage that can hold the heel of the foot can be firmly wrapped heel stably.

On the other hand, the concave groove 300 into which the cloud body 200 is inserted is formed on one side of the midsole 122 in contact with the bottom surface of the insole 110 of the portion constituting the sole (120).

The size of the concave groove 300 will be sufficient if the rolling body 200 to be inserted is only slightly large enough to be able to slide in the left and right or front and rear directions. In addition, when the cloud body 200 is inserted into the concave groove 300, the upper surface of the concave groove 300 and the bottom of the injection molding 210 are slightly spaced apart, preferably having a margin of about 1 to 5 mm. It will be enough.

When the falling distance is less than 1mm, the bottom surface of the insole 110 and the top surface of the sole 120 is too close to expect the effect of the cloud movement by the cloud body 200 at all, if it falls more than 5mm cloud movement This may occur smoothly, but the movement of the sole of the foot is too large, which may cause inconvenience in walking.

Therefore, it is desirable to space the above degree in order to allow a proper rolling movement but to give comfort in walking. In addition, when the outer surface of the concave groove 300 is also made of a relatively hard material such as injection molding, the rolling motion of the rolling body will be more effective.

When the cloud body 200 is provided around the center point P of the foot as described above, when the force is moved from the heel to the outside to the tip of the toe, the cloud body 200 becomes the center of the cloud movement as shown in FIG. 4. Likewise, force transmission is performed in the front and rear and right and left directions by the seesaw principle, which extends to the entire surface of the insole 110 by sliding motion through the concave groove, so that the force can be easily transmitted and the correct walking can be made naturally.

That is, as shown in Fig. 4, according to the iso principle, a natural rotational motion, that is, cloud motion, occurs about the center point of the center when the force is transmitted from one end to the other end, which makes it possible to move with less force. will be. When applied to walking, it is possible to move only by a small force (less ground reaction force) transmitted to the sole during the same walking, which has the advantage of reducing the impact on the knee. In addition, since there exists a cloud body on the ground reaction trajectory, the cloud becomes the center point and the force is transmitted to the ground reaction trajectory, thereby inducing correct walking.

Next, Figure 5 is a view according to another embodiment of the present invention. As shown, in this embodiment, the injection molding 210 'having a plurality of rolling bodies 200' is provided on the bottom of the insole 110 corresponding to the movement trace of the ground reaction force. In addition, a concave groove corresponding to the cloud body 200 ′ is formed on the midsole 122 surface of the sole 120 corresponding thereto according to the movement trajectory of the ground reaction force. Of course, even in this case, the concave grooves may be made of an injection molding which is a hard material.

Even in the case described above, the cloud 200 'will be positioned to have a margin of about 1 to 5 mm as in the case of FIG. 3 described above. In this embodiment, the cloud body 200 'is formed in three parts such as a heel part, a center point, and an anterior part, thereby enabling more efficient cloud motion.

Meanwhile, in the above-described embodiment, the rigid injection molding 210 'is positioned at the bottom of the insole 110 according to the movement trajectory so that the force transmission due to the rolling motion by the rolling body is transmitted as it is according to the movement trajectory of the ground reaction force. The advantage is that more effective cloud walking is possible. This operation principle will be described later through the operation process. However, in the present embodiment, the largest feature is that a plurality of rolling bodies are arranged on the movement trajectory of the ground reaction force in the case of normal walking.

Next, another embodiment of the present invention will be described with reference to FIG. 6. As shown, this embodiment is basically similar to the embodiment of Fig. 3, but the rolling body 200 "is formed in the shape of a roller, not in the form of a ball. Since the rolling motion is made only in the direction, the roller is positioned on the movement trajectory of the ground reaction force, and thus the roller is positioned in the movement trajectory direction, so that sufficient rolling movement is possible as in the embodiment of Fig. 3. Of course, in this case, the outsole 120 Roller groove (300 ') is formed in the corresponding portion of the), it will be preferable that the roller groove (300') is made of an injection molding.

7 is a view according to another embodiment of the present invention. As shown, in the present embodiment, only the insole 110 is shown. That is, in a general shoe, the sole 120 is integral with the upper, but separates the insole 110 separately, so that it is easy to replace with a new one, so that it can be used in existing shoes. That is, as shown in Figure 7, the insole body (110a) and the insoles made of irradiated (110b). The insole 110 is to be provided with a concave groove 112, the concave groove 112 may be made of an injection molding. In addition, the insole irradiated output (110b) is molded into an injection, it represents a case where the cloud body 200 is integrally injected to the position located on the movement trajectory of the ground reaction force.

Therefore, the cloud body 200 is coupled to the concave groove 112 position formed on the bottom surface of the insole body 110a, as described above, the insole support project 110b in a state to have a margin of about 1-5mm It is coupled to the bottom of the insole 110a. Therefore, in this case, the recessed grooves corresponding to the rolling bodies do not need to be provided in a separate outsole. Therefore, even by replacing only the insole 110 made by combining the insoles of the present invention 110b and the insole body 110a in the existing general sneakers can achieve the object of the present invention sufficient in the general shoe. .

Next will be described in detail the operation of the present invention configured as described above. First, the following description will be made with reference to FIG. 3, and the following principles will be applied to all cases of FIGS. 5, 6, and 7.

First, in the case of Figure 3 will be described a case where the cloud is present at the center point (P) of the foot. In this embodiment, since the injection molding 210 wraps a portion corresponding to the bottom heel of the insole 110, the heel can be stably supported when the shoe 100 is worn. In this state, when the foot begins to step on the heel for walking, the transmission of force depends on the movement of ground reaction force. In this case, the cloud body 200 located at the center point P of the foot is floating with some space (about 1 to 5 mm) on the top surface of the sole 120 and the bottom of the insole 110. Therefore, the rear part corresponding to the heel of the cloud body 200 is pressed by the force by the force transmitted from the heel, and thus the cloud body 200 is positioned in a slightly lifted state of the front part.

Afterwards, the rolling body 200 has a rolling motion in the concave groove 300 from the rear part to the front part by the continuous force transmission gradually, and the rolling motion more easily transmits the force from the heel to the front part. The user will be able to walk comfortably walking clouds, and will be able to exercise in the assembly according to the movement trajectory of the ground reaction force.

That is, as shown in Fig. 6, when the force applied to one end by the seesaw principle is gradually transferred to the other side, the weight movement is naturally shifted around the center of the seesaw, which leads to a flexible rolling motion.

And, as described above, if the O-shaped legs are present, the force transmission is outward from the movement trajectory of the normal ground reaction force, but even in this case, the rolling body 200 which is the center point of the seesaw motion Since it is located at the center point (P), the ergonomic shape in which the force transmission is more outward than the normal case also primarily shows the effect of the cloud motion by the seesaw motion by the cloud body 200. It is also suitable for calibration as it can be changed to. Of course, even in the case of the X-shaped legs, the direction of force transfer gradually reaches the normal ground reaction trajectory due to the seesaw motion principle of the rolling body 200 located at the center point P of the foot from the inside. .

Next, the case of FIG. 5 will be described. As shown in FIG. 5, in the present embodiment, the cloud body is provided with a heel, a center point, and an anterior part. The overall force transfer also gradually moves from the heel to the toes. In this case, the force transmitted to the first heel is a cloud motion based on the seesaw principle through the first cloud body 200 ′ at the rear, thereby enabling a more smooth power transmission and cloud motion than normal. Then, the transmitted force is a rolling motion occurs through the second cloud body 200 'located at the center of gravity point (P), and again through the third cloud body 200' located at the front of the foot Can be achieved. Therefore, in the case of overall walking, the seesaw movement is possible through each cloud body 200 'when the force is transmitted from the heel to the front part, so that the smooth walking of the cloud is more easily possible. Of course, even in this case, the O-shaped legs and the X-shaped legs will be able to gradually walk normally as the seesaw movement is performed by each cloud body. 6 and 7 are also implemented by the same operating principle, detailed description thereof will be omitted below.

As described above, in the present invention, there is a main point to achieve the cloud walking by the seesaw motion by the cloud body on the movement trajectory of the ground reaction force, the configuration and operation according to the embodiment for the above description and the drawings Although illustrated according to the present invention, it is merely an example, and various changes and modifications are possible without departing from the technical spirit of the present invention.
