SHOES HAVING A HEEL HAVING THE OTHER ELASTIC FORCE AND EXCHANG}

The present invention relates to a shoe having a replaceable heel body, and more particularly, to provide a heel block by replacing the heel block to be suitable for a variety of wearer's weight or gait, etc. The present invention relates to a shoe having a heel which is easy to adjust and replace, which cushions and distributes a body load to mitigate an impact with the ground.

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 cushion 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. This is 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 the number of feet in contact with the ground is 1000 times per 100m during running, when the force of 2-3 times the weight acts as a repetitive load, the degenerative change in the joint occurs if sufficient shock absorption is not achieved. It is also associated with low back pain.

Therefore, it is desirable to select sneakers with good cushioning.

Cushionung is the damping of force between two colliding objects (foot and ground when running). Human musculoskeletal system (muscles, bones, joints and ligaments) is a natural moderate shock absorber, which causes pronation, which is the medial rotation of the foot during natural shock absorption, and the degree of knee flexion when the foot touches the ground. It is known to affect the amount of impact.

According to the 1988 Adidas Research and Innovation Lab and the University of Calgary University of Nigg et al. (1998), the amount of force generated when the knee touches the ground is defined as the VFIP (Vertical Force Impact Peak). Larger numbers increase VFIP. Factors affecting the size of the VFIP include weight, kinematic factors, speed, and surface, and it is reported that the higher the speed, the higher the VFIP. At this time, the VFIP of a runner who runs hard tracks is reported to be more than five times the weight.

Figure 1 schematically shows the weight impact site close to the sole of the foot during walking, as shown in Figure 1 (a) the impact force during the VFIP occurs during the initial 20-30ms when the foot touches the ground is greater than the weight In other words, the weight was 2.2 times the impact, and as shown in Figure 1 (b) after the soles all touch the ground, the weight was greater than the support capacity, the next run as shown in Figure 1 (c) The force generated during the 100ms before the forefoot touches the ground and propels the propulsion force is greater than the body weight, 2.8 times the weight.

In this way, it can be seen that the amount of impact applied to the sole in walking or running is more correlated with the weight.

The study of the heel of the body having a function of absorbing impact force in the internal structure of shoes has been continued in terms of injury prevention. Most of these studies, however, do not take into account weight, an internal factor that affects the load experienced by the body.

Some people with heavy weights are more likely to be exposed to injuries while driving, especially in the early stages of driving, with higher weights having a higher incidence of injury than normal weights (Pollock et al. 1977).

However, the shoes produced are indistinguishable from those weighing 50kg or 100kg, so the elasticity of the heel and the weight of the wearer are not optimally balanced, and thus the shock cannot be absorbed due to the body load on the foot. And it was found that there is a problem that the foot and ankle is not dispersed, or the whole shoe is changed and the foot or ankle surgery is often performed to solve the inconvenience and decrease the elasticity during long-term use.

Accordingly, the present invention has been made in order to solve the above problems, the present invention is to provide individual walking by providing a prefabricated resilient body having the most suitable resilience according to the weight when the foot of the shoe wearer in contact with the ground during walking or driving It is an object of the present invention to provide shoes that can be recombined or selected according to characteristics to provide comfortable walking.

In order to achieve the above object, the shoe having a prefabricated heel body according to an embodiment of the present invention, in the shoe consisting of an upper (upper) covering the top of the foot and the sole (sole) of the foot contacting the ground, The bottom material, the front sole and the front bottom; A midsole that serves as a shock absorber, wherein an empty space is formed in the rear bottom portion; And it is coupled to the empty space of the rear bottom surface of the front sole and the midsole, removable member consisting of; the adjustment member, the coupling member is fixed through the rear upper surface of the front sole and one side of the midsole; A coupling spring to which the front portion is detachably coupled to the coupler; A rear sole which is detachably coupled to the rear portion of the coupling spring; And a rear heel is detachably coupled to the upper surface of the rear sole; consisting of a combination of the rear heel, rear sole and coupling springs and disassembly of the adjustment member by providing a shoe that is easy to adjust the hardness and exchange the heel It has its technical features.
And preferably, the rear heel is formed, the inner groove is formed through the upper surface inside, the hardness adjustment projection corresponding to the inner groove is provided so that the hardness of the heel is made by various combinations of the hardness adjustment projection.

2 and 3 does not show an upper covering the upper part of the foot, but since the upper may be formed in any form, it will not be mentioned separately. In the present invention, as shown in relation to the sole (sole) constituting the shoe except the upper, in the shoe forming a sole (sole) 10 of the foot in contact with the ground, the bottom 10 in terms of material Looking at the outer surface and the first contact with the outer surface is mainly made of a rubber sole and a shoe sole to control the shock absorption and elasticity of EVA (EVA) material or polyurethane (PU) material made of a large midsole (30) . Of course, the outsole 20 may be formed in various forms, such as a heat-modified rubber, such as synthetic resin TIPS (TPR), such as polyurethane (PU) in addition to the rubber material. This may be any material as long as it satisfies the traction enhancement and anti-slip function, which is a unique function of the outsole 20. Similarly, the midsole 30 may also be made of various materials.

Next, the structural aspect can be divided into a front portion (a) to protect the front portion of the foot and a rear portion (b) to protect the rear portion. The present invention focuses on changing the structure of the rear part (b), which is the rear part of the structural shoe, to provide a variety of replacement and shock absorption or customized shoes to suit the characteristics of each individual. It will be described in detail below.

First, the sole 20 will be described. The sole 20 is intended to perform the purpose of improving the conventional non-slip traction, such as the first contact with the outside of the ground, as described above, various materials such as rubber, polyurethane (PU), TPR (TPR) Can be done with. This sole 20 is made of a front sole 22 and the rear sole 106. The rear sole 106 is coupled to other parts of the midsole to be described later to be assembled and disassembled to meet the needs of various consumers.

Since the midsole 30 plays a role of conventional shock absorption and elasticity control, the midsole 30 is made of EVA or PU material, which is conventionally used, and has a C hardness of 50. It is the same as a normal midsole material by about 55-55. However, the structure of the rear portion (b) of the midsole, so as to form a hollow space is formed in the rear bottom portion as shown. It is a feature of the present invention to disassemble and combine the various types of adjustment member 100 to be described later in the empty space.

Hereinafter, the adjusting member 100 will be described. Adjusting member 100 is to be made of a coupling hole 102, the coupling spring 104, the rear sole 106 and the rear heel 108 in the order in which they are coupled. First, the coupler 102 will be described. As shown, the coupler 102 is coupled to and fixed through a rear upper surface of the front sole 22 and a portion of the bottom surface of the midsole 30. Such a coupler should be made of a harder than a normal front outsole 22 because it should be less shaken or deformable as a center coupling portion to allow the separation of the adjustment member to be made, and should be made in the form of an injection molding. The bottom of the coupler 102 may be made in various forms, such as adhesive or high frequency fusion in order to be fixed to the front upper sole rear surface. In addition, the guide groove 102a and the guide piece 102b are formed on the upper portion of the coupler so that the coupling spring 104 to be described later is coupled thereto. On the other hand, the coupler 102 is basically fixed to the front surface of the front sole, after coupling the remaining portion of the adjustment member, such as the coupling spring 104 to be described later, and finally fixed to the bottom of the midsole 30 By engaging, the coupler 102 is firmly fixed to the shoe itself without being separated.

Next, the coupling spring 104 will be described. The coupling spring 104 serves as a support for supporting the rear sole 106 and the heel 108, which will be described later, and at the same time, provides an elastic restoring force to play a role of absorbing shock of the shoe. The overall structure of the coupling spring 104 is to be made in a plane, it is also possible that the rear portion is formed to be slightly inclined upward compared to the front portion. The engaging portion is formed at the front end portion so that the engaging protrusion and the front portion are seated and coupled to the guide groove 102a of the coupler 102. At this time, the front portion of the coupling spring 104 is supported by the guide piece 102b, so that movement in both directions is limited, so the direction of movement of the coupling spring is limited only in the up and down direction, thereby providing elastic restoring force.

That is, after the coupling spring 104 receives the force in the vertical direction of the ground by the load transmitted through the sole when walking, the force is applied to the heel when the force transmission according to the walking is made of the front part of the foot, so that the coupling spring By the elastic restoring force of (104) it is possible to assist in walking while at the same time recovering the original.

On the other hand, the rear portion of the coupling spring 104 is to be coupled to the rear sole 106. That is, the bottom surface of the rear sole 106 to form a sole groove (106a), the rear portion of the coupling spring 104 is inserted into the sole groove 106a so that the coupling spring 104 and the rear sole 106 ) Are combined. Since the rear sole 106 serves as a sole, it is to be made of a conventional material for improving the anti-skid grounding, but can be combined and disassembled so that the rear sole 106 of the various soles according to the strength of the sole material It can be provided. That is, since the most frequently worn out part of the shoe part is the rear sole 106 part, not only this part can be replaced, but also various forms such as replacing and combining the high sole or the anti-abrasion rear sole 106 according to physical conditions. Rear sole 106 can be replaced and coupled. In addition, an inner groove 106b is formed in the upper surface portion of the rear sole 106, and a rear heel 108 to be described later is coupled to the inner groove 106b.

Next, the heel 108 will be described. The heel 108 is to be basically made of EVA or polyurethane (PU) material to perform the role of the midsole. Of course, in addition to the role of the midsole will be available in a variety of materials, such as TPU or rubber material. The biggest feature of the heel 108 is to be made of a variety of forms of hardness. By providing the heel body 108 of various hardness, it is possible to provide a shoe of a customized form by providing a heel body suitable for the characteristics of each individual. The bottom surface of the rear heel 108 is made to have a shape corresponding to the inner groove 106b formed on the upper surface of the rear sole 106 to be coupled to the rear sole 106. In addition, the front portion of the rear body 108 is formed with a protrusion 108a, and the midsole 30 is formed with a protrusion groove 30a corresponding to the protrusion 108a so that the rear body 108 is coupled to each other. ) Make sure that the tight coupling is achieved. That is, the rear heel 108 is coupled through the protruding groove 30a of the rear sole 106 and the midsole 30, so that after the coupling, it is possible to maintain a firm coupling without movement or departure.

On the other hand, with reference to Figure 4 shown will be described another form of the heel body 108.

As shown, the heel body 108 is to be formed with a plurality of heel body grooves (108b), and to be provided with a hardness control projection (108c) coupled to the heel body groove (108b). Therefore, the hardness control of the entire heel according to the coupling of the hardness control projection (108c), or to make it possible to partially adjust the hardness. That is, in the heel of the Figures 2 and 3 described above, the hardness is adjusted through various hardness of the heel itself, in the present embodiment, the hardness is made in various forms and parts through the hardness control projection 108c It becomes possible. It will be described with reference to Figure 5 showing an example of the hardness control using the hardness control projection (108c).

As shown, (a) of FIG. 5 shows a case of Heavy Cushion. In the case of valgus valgus, it is necessary to make shoes with soft cushion as much as possible because the recovery ability is delayed even for small wounds. Therefore, in this case, the hardness adjustment projection 108c is made of the softest projection, for example, by using the hardness adjustment projection 108c made of about 70 to 80 as the C type (C Type) hardness is made as soft as possible To lose. In the case of Fig. 5B, the case of the vulgar group Varus is shown. In the case of the outer leg is a relatively large force is applied to the outer part of the foot wears out quickly because the outer part will continue to walk if left unattended and cause abnormality in the musculoskeletal system. In the case of such a sub-group, it is necessary to gradually lead to have a normal walking habit by distributing the force relatively to the inside of the foot. Therefore, by inserting a hardness control projection 108c made of a relatively high hardness in the heel groove 108b corresponding to the outer portion of the foot so that the hardness of the outer and inner portions of the foot is different. Therefore, when the shoe is equipped with such a heeled shoe 108, the force applied to the foot when walking is relatively low in hardness, so a lot of force is applied to the outer part, and the outer part of the foot gradually becomes the same form as the inner and outer sides. As it is possible to walk in the form of force applied, it can be possible to treat the outskirts. In the case of (c) of Fig. 5, it shows the case of (Valgus) in the case of the inner group is a case where the relative force is applied to the inner part as opposed to the outer group in this case corresponds to the inner part as opposed to the outer group. Treatment is possible by inserting a hardness adjustment protrusion 108c made of high hardness into the heel groove 108b.

As described above, since the combination of various hardness and materials of the heel 108 and the rear sole 106 is possible, various customized shoes are possible according to each individual.

Next, in the shoe of the present invention made as described above will be described the coupling and exchange process of the heel and the rear sole.

First, the combining process will be described. The front sole 20 and the midsole 30 according to the present invention are prepared through a separate process. The coupler 102 is fixedly coupled to the rear upper surface of the front sole 20 through an adhesive or high frequency fusion. Thereafter, the front portion of the coupling spring 104 is fitted into the guide groove 102a of the coupling hole 102 to be coupled. In the above state, the upper surface of the coupler 102 is fixedly bonded to the bottom of the portion where the empty space of the midsole 30 is formed by an adhesive or other method. Therefore, since the coupler 102 is firmly coupled through the upper surface of the front sole 20 and the bottom of the midsole 30, the coupler 102 may serve as a support for the entire coupling of the adjusting member 100. Then, the rear sole 106 is engaged by engaging with the coupling spring 104 through the sole sole 106a of the rear sole 106. In the above state, after the heel body 108 is coupled with the rear sole 106, the protrusion 108a of the heel body 108 is fitted into the protrusion groove 30a of the midsole 30 so that the heel body 108 is fixed. ). Accordingly, the rear sole 108 may be firmly coupled and supported through the rear sole 106 and the midsole 30. Meanwhile, unlike the above combination, the rear sole 106 and the rear sole 108 may be In the first coupled state, the protrusion 108a of the heel body 108 is coupled to the protrusion groove 30a of the midsole, and at the same time, the coupling hole 102 may be fixed to the bottom of the midsole 30. In any type of coupling, the coupling of the coupler 102 is the main focus of the coupling through the bottom surface of the front sole 20 and the midsole 30 is fixedly coupled to serve as a support.

Next, the process of decomposition and recombination of various types of control members will be described. If it is necessary to adjust the hardness of the rear sole or wear of the rear sole due to normal walking, by lifting the rear portion of the midsole 30 by force, the rear heel 108 is forcibly separated from the shoe. In such a state that the rear heel 108 is separated, so much free space is formed, so that the rear sole 106 can be easily separated from the coupling spring 104 and removed. Of course, the coupling spring 104 can also be separated from the coupling sphere (102). Since the coupler is fixed through the bottom of the front sole 22 and the midsole 30 is not removable. As the coupling spring 104, the rear sole 106 and the rear heel 108 can be separated as described above, the rear sole 106 or the rear heel 108 can be reversed in any combination according to the characteristics of each individual. After coupling in the order of, by combining the midsole 30 with the heel 108, it is possible to disassemble the coupling of the heel portion of the prefabricated shoes. Although the configuration and operation of the heel body according to the present invention have been described in accordance with the above description and drawings, this is merely an example, and various changes and modifications are possible without departing from the technical spirit of the present invention. .
