More particularly, the present invention relates to a functional shoe having shock-absorbing means interposed between an outer sole and a midsole, wherein said shock-absorbing means includes: a lower member coupled to the upper surface of the outer sole; an upper member coupled to the lower surface of the midsole; and a shock mitigation member to which a lower shock mitigation part and an upper shock mitigation part are alternately attached, wherein said lower shock mitigation part is bent into a round shape, and both ends thereof are bonded to the side surface of the lower member forming a tunnel shape, and said upper shock mitigation member is bent into a round shape, and both ends thereof are bonded to the side surface of the upper member forming an inverted tunnel shape. Thus, the shoe of the present invention absorbs shocks at the heel part and at the toe part of a foot, on which the largest load is applied while walking, and quickly rebounds from the ground at the same time by an elastic force, thereby providing a wearer with feeling of optimum stability.

Description

Functional shoes with both shock absorption and resilience

The present invention relates to a functional shoe made of both shock absorbing and rebound elasticity, and more particularly, to a functional shoe made of both shock absorbing and rebound elasticity at the same time by maximally harmonizing mutually symmetrical shock absorbing and rebound elasticity in the function of the shoe. It is about.

In general, a shoe protects a person's foot. When a shoe is running or walking, the shoe is blocked from the outside and the foot is protected.

If a person weighing about 60kg walks an average of 6000 steps per day, the foot will carry a load of about 432 tons, which is more than the weight of the jumbo for international flights (about 400 tons).

As such, the simplest way to develop a shoe for absorbing impact on the sole is to lower the hardness of the shoe. If we define the cushion as simply reducing the maximum force, a good cushion can be defined as absorbing the shock to the extent that it does not overwhelm the skeletal muscle system. However, in addition to cushioning, propulsion is an important factor in athletic performance, so it is not good for a given force to be completely absorbed by the cushioning system. After all, this is a complex problem and it is not easy to define the optimal shoe hardness for the shock shock absorption of skeletal muscle against repeated impact forces. Because you need to know information about the magnitude of the force.

As a result of analyzing the ground repulsion force using the pressure plate, it can be seen that the magnitude of the vertical force between the ground and the foot appears 2-3 times the weight. If your feet are touching the ground about 1000 times per 100m when running, when the force of 2-3 times the weight acts as a repetitive load, if the shock is not absorbed enough, the joint will degenerate. It is also associated with low back pain. Therefore, it is desirable to select a good sneaker with a cushion that is well absorbed well.

Figure 1 schematically shows the weight impact site close to the sole of the foot during walking, as shown in Fig. 1 (a) during the initial 20-30ms when the foot touches the ground, the impact force is greater than the weight, that is, the weight of The impact was 2.2 times, and as shown in FIG. 1 (b), when the soles all touched the ground, the body weight was larger than the supporting force, and as shown in FIG. The force generated during the 100ms until the forefoot touches the ground and reaches the ground is reported that the driving force is greater than the weight, that is, the load is 2.8 times the weight.

In this way, it can be seen that the amount of impact applied to the soles of walking or running is larger than expected.

Therefore, in order to alleviate such a shock, various types of shock absorbers, for example, cushioning members such as air bags or sponge foams, are used. However, when the shock absorber is used, the shock absorber is somewhat effective. However, the better the shock absorber, the lower the repulsive force, and the more the fatigue is accumulated when walking or running for a long time.

That is, in the structure of shoes, the shock absorption to be reduced when stepping on the foot and the rebound elasticity to be increased when the foot is symmetrical are symmetrical, and when one satisfies one, there is a double problem of sacrificing the other.

The present invention has been made to solve the above problems, the present invention is to absorb the impact applied when the foot of the shoe wearer in contact with the ground while running, on the contrary to increase the resilience when bumping the ground shock absorption and rebound elasticity The purpose is to provide functional footwear with improved functionality.

The present invention for achieving the above object is a functional shoe having a shock absorbing means mounted between the outsole and the midsole, the shock absorbing means, the lower member is coupled to the upper side of the outsole; An upper member coupled to a lower side of the midsole; The lower impact portion which is bent in a round shape and both ends are combined with the side surface of the lower member to form a tunnel shape, and the upper impact portion which is bent in round shape and both ends are combined with the side surface of the upper member form an inverse tunnel shape are alternately arranged. And a shock absorbing member coupled to each other, wherein the shock absorbing and rebounding elasticities are simultaneously achieved using the absorbed resilient elastic force as well as the shock absorbing by the lower impact part and the upper impact part.

And, the lower impact portion and the upper impact portion is characterized in that the center line coincides.

And, the upper member is characterized in that the wing pieces protruding to both sides and the rear side to further surround the lower side of the midsole.

The front end of the upper member and the front end of the lower member are connected, and the rear end of the upper member and the rear end of the lower member are connected.

As described above, the present invention has an effect of providing optimal stability to the wearer because the rebound elasticity is quickly made at the same time as the shock absorbing at the heel and the front part of the foot where the load of the foot is most applied.

Hereinafter, with reference to the accompanying drawings will be described a functional shoe made at the same time shock absorption and rebound elasticity.

Figure 2 is a perspective view showing a functional shoe made of a shock absorbing and rebound elasticity at the same time according to the present invention, Figure 3 is a perspective view showing a shock absorbing means of a functional shoe made at the same time the shock absorbing and rebound elasticity according to the present invention.

2 and 3, the shock absorbing means 1 mounted between the outsole 4 and the midsole 2 of the present invention is the lower member 10 is coupled to the upper side of the outsole 4 Wow; An upper member 20 coupled to a lower side of the midsole 2; The lower impact portion 32, which is bent in a round shape and both ends are combined with the side surface of the lower member 10, forms a tunnel shape, and both ends are bent in a round shape, and both ends are combined with the side surface of the upper member 20. The shock absorbing member 30 coupled to the upper impact portion 34 to form a shape alternately arranged; consists of.

Hereinafter, each configuration will be described in detail.

First, in the present invention, a space is formed between the outsole and the midsole of the heel portion of the shoe 100 to couple the shock absorbing means 1, and the material of the shock absorbing means 1 of the present invention is made of polyurethane and reinforced plastic. The mixed material is used to have high strength and hardness and strong elasticity, but is not limited to polyurethane or reinforced plastics, but various materials having high strength and hardness and good resilience can be used.

Lower member 10 according to the present invention is coupled to the upper surface of the outsole 4 of the heel portion of the shoe 100, the shape corresponds to the shape of the upper surface of the outsole (4). Thus, when the outsole 4 has a flat upper surface, the lower surface of the lower member 10 is also flat and coupled. However, in order for the shock absorbing means to be strongly coupled between the outsole and the midsole, a protrusion (not shown) is formed on the upper surface of the outsole in a transverse direction, and the lower member 10 protrudes in a transverse direction correspondingly. It is preferable that the groove 12 is formed to couple the lower member 10 to the outsole 4 after the protrusion (not shown) is inserted into the protrusion groove 12. When the impact of the large shear force is applied to the shoe 100, the flatly coupled lower member 10 may be displaced apart and damaged, but as described above, the lower member 10 may withstand the large impact.

The upper member 20 according to the present invention is coupled to the bottom surface of the midsole 2 of the heel portion of the shoe 100, the shape of which corresponds to the shape of the bottom surface of the midsole 2. Thus, when the lower surface of the midsole 2 is flat, the upper surface of the upper member 20 is also flat and is strongly coupled.

Preferably, the upper member 20 surrounds the lower side and the rear side of the midsole 2 so that the shock absorbing means 1 is strongly coupled between the outsole 4 and the midsole 2. It is preferable that the wing pieces 22 protruding to both sides and the rear side so as to be further provided.

The wing piece 22 is made of the same material as the upper member 20, and the front side is opened and formed on both sides and the rear side like a support wall. That is, since the support wall is formed by the blade piece 22, when the midsole 2 is seated and coupled to the upper surface of the upper member 20, the midsole 2 and the shock absorbing means even in severe impact (1) is not separated from each other.

As shown in Figure 4, the shock absorbing member 30 according to the present invention is bent in a round, both ends are combined with the side of the lower member 10, the lower impact portion 32 to form a tunnel, round It is bent so that both ends are joined to the side of the upper member 20 to form an upper impact portion 34 to form a reverse tunnel alternately. This is because the alternating space generated by the role of the cushion to reduce the friction generated by the collision with each other, and the bending elastic force is increased by the rebound elastic force is reduced to reduce the consumption of the force pushing the ground.

Here, the lower impact portion 32 is usually long oval long oval, and is coupled to the outer surface of the outsole (4). And, since it is alternately disposed with the upper impact portion 34, the lower impact portion 32 is formed in a plurality at a predetermined interval. The width can be adjusted in various ways.

Preferably, when the lower impact portion 32 is assumed to be a semi-ellipse, the long axis and the short axis of the lower impact portion 32 disposed in the center are the longest and the length thereof becomes shorter toward the front and rear. This is because the load of the middle portion of the heel of the sole structure of the person acts the most, since the corresponding portion is the center of the lower impact portion 32, it is easy to absorb the shock when the length and width are long.

Here, the upper impact portion 34 also has a long elliptical long axis like the lower impact portion 32, it is coupled to the outer surface of the midsole (2). Then, the coupling between the lower impact portion 32, the lower impact portion 32 and the upper impact portion 34 is to be coupled while being alternately arranged.

As described above, when the upper shock part 34 is also assumed to be a semi-ellipse, the long axis and the short axis of the upper shock part 34 disposed in the center are the longest.

Therefore, the shock absorbing member 30 is composed of the upper impact portion 34 and the lower impact portion 32, so that the shock absorbency is 1000N / 3.5ms ~ 1200N / 3.5ms and the propulsion according to the repulsive elasticity is absorbed Allow about 20% of the power to be promoted.

As shown in Figure 5, the left foot was wearing the functional shoes of the present invention and the right foot was worn conventional shoes to compare the pressure, force, area and the like.

When a person walks or runs, it can be seen from the graph of the right foot wearing conventional shoes that the pressure is concentrated on the heel and the heel. However, according to the graph of the left foot wearing the present invention, it can be seen that when the pressure is reduced, the propulsion force enters less.

Preferably, the impact mitigating member 30 is preferably coupled to the center line of the lower impact portion 32 and the upper impact portion 34 to match. That is, the upper surface of the highest point of the lower impact portion 32 and the lower surface of the lowest point of the upper impact portion 34 should be arranged in a straight line. This is to equally absorb the shock transmitted to the shoe 100, the shock is absorbed only in one direction when the arrangement is shifted, the life of the shock absorbing means 1 is shortened.

Preferably, the front end of the upper member 20 and the front end of the lower member 10 is connected, the rear end of the upper member 20 and the rear end of the lower member 10 is connected. good. This is because the structure of the sole of the person is a shape in which the bone is dug in the middle portion than the heel and heel, so that the front end of the upper member 20 and the front end of the lower member 10 should be connected to correspond to the shape. do.

In addition, as described above, since the center portion of the heel receives the greatest load, the width and length of the upper member 20 and the lower member 10 are increased toward the front and rear from the center to absorb the same impact. Will be reduced. Thus, the front end of the upper member 20 and the front end of the lower member 10 are connected, the rear end of the upper member 20 and the rear end of the lower member 10 should be connected to the center height The largest and the height becomes smaller toward the front and rear, the upper member 20 and the lower member 10 may be mounted.

As shown in FIG. 6, (a) shows that the shock absorbing member is completely relaxed when the user does not wear shoes, and (b) shows that when the user wears shoes, a strong shock is applied. It shows that the shock absorbing member is compressed.

Next, an embodiment of a functional shoe made at the same time the shock absorption and rebound elasticity according to the present invention.

When the wearer runs or walks, the wearer wears the functional shoe 100 made of the shock absorbing and resilient elasticity of the present invention. When running or walking, the load of the wearer is transmitted to the shoe 100, and the shock applied when the foot of the wearer comes into contact with the ground absorbs the shock absorbing member 30 of the shock absorbing means 1 as much as possible. On the contrary, when impacting the ground, the shock-absorbing member 30 is relaxed while increasing the resilience to reduce the consumption of force and protect the knee.

As described above, the present invention has a basic technical idea of alternately arranging the lower impact portion of the tunnel shape and the upper impact portion of the reverse tunnel between the outsole and the midsole of the shoe, which is merely exemplary, and is common in the art. Those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom, and the true technical protection scope of the present invention should be defined only by the appended claims.

The present invention can be used in functional shoes made of both shock absorption and rebound elasticity, and more specifically, functional shoes made of both shock absorption and resilience at the same time by maximally harmonizing mutually symmetrical shock absorption and rebound elasticity in the function of shoes. It is available for.
