Description

FUNCTIONAL SHOES FOR THE EXTENSION GROWTH}

The present invention relates to a shoe, and more particularly, to minimize the impact on the knee cartilage by absorbing and dispersing the load applied by the action applied during walking, the heel portion to help the kidney growth by resilient elastic resilience It relates to a functional shoe for promoting kidney growth to ensure that only the concentrated stimulus is transmitted to prevent damage to the human body and stimulate the growth plate according to the shock absorption.

In general, the growth of a person means the increase in the size and height of the body as the cell proliferation and hypertrophy, the growth of the kidney refers to the growth of bones and muscles around the bones together. If you look at the growth of human kidneys in terms of bones, the spine and leg bones, called the spinal column is the largest role. In particular, the growth of the leg bone is caused by the growth hormone secreted from the anterior pituitary gland stimulates a site called pelvic cartilage or growth plate in the hip and ankle of the hip, causing cell division to grow the length of the bone, resulting in elongation.

It is widely known that proper stimulation of growth plate through proper exercise is effective for such growth, and stimulation by jumping action such as jumping rope, basketball, etc. can promote bone growth by activating cell division of growth plate. Known. The jump is achieved by stimulation through the soles, in particular through heel stimulating the growth plate of the knee. The growth plate stimulation of the knee joint by the direct impact stimulation helps the kidney growth, but the adverse effect is not enough. In other words, one of the important functions in the shoe is a shock absorbing function, which is the impact that is transmitted through the soles of the ground and the first contact in the running, such as running, jumping will damage the human body, and in severe cases will cause damage to the knee cartilage. In addition, if the stress absorbing ability is excessively emphasized, there is a problem in that walking becomes uncomfortable due to the lack of resilience. Therefore, the proper balance of shock absorption capacity and rebound elasticity is the important function of shoes. Hereinafter, the shock absorption and rebound elasticity will be briefly described. 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 also an important factor in athletic performance, so it is not good for a given force to be fully 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 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 can be seen that it is desirable to select a good sneaker with good shock absorption.

However, the shock absorbing ability applied when landing and the resilience elasticity applied when walking are symmetrical with each other, and when one function is strengthened, there is a contradiction to sacrifice the other.

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 weight was greater than the supporting force, and as shown in FIG. 1 (c), the propulsion was performed for the next run. 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 greater than expected. Therefore, in order to alleviate such a shock, various types of shock absorbers, for example, cushioning members such as airbags or sponge foams, are used. However, when such a shock absorber is used, the shock absorber is somewhat effective, but there is a problem in that it is more difficult to walk or run by reducing the ground repulsion force.

That is, in the structure of the shoe, 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.

As briefly described above, it is very difficult to develop shoes in consideration of the important shock absorbing ability, resilience elasticity in the shoes, and in parallel with the appropriate stimulus to help the kidney growth. In particular, it is a very difficult concept to deliver a stimulus that helps kidney growth while utilizing shock absorbing ability and resilience.

Looking at existing known devices for promoting kidney growth, for example, according to Korean Patent Laid-Open Publication No. 10-2005-116030, a device for promoting bone growth by artificial gravity is disclosed. Such a device is a device that helps to promote growth by giving a certain stimulus to the growth plate of the human body, but a device that is expensive and fixedly used in a certain place, there are many restrictions to be widely used in daily use.

According to Korean Patent Laid-Open Publication No. 10-2005-39686, the structure of the growth plate is stimulated through direct impact through the sole by changing the hardness of the sole constituting the shoe. In particular, the sole (insole, midsole outsole) to take the structure to strengthen the impact of the entire sole by strengthening the hardness of the midsole, but there is a problem that the wearing feeling of the shoe is significantly reduced under the above structure. And, above all, the structure of inserting the hardness control member into the corresponding portion of the midsole corresponding to the heel portion for the growth of the heel, but this does not take into account the shock absorbing dispersion ability, but simply by stronger impact transfer Direct stimulation of the heel promotes kidney growth, so it may be suitable as a stimulus for growth, but rather there is a problem of promoting damage to the knee cartilage.

In addition, in normal sneaker running shoes, the function to absorb the impact of the load applied is mainly in the midsole (midsole), in consideration of the shock absorbing power, etc., in general, based on the ASKER Type C hardness tester 50 to 60 degree and the repulsive elasticity according to the repulsive elasticity of about 40 to 45% is used, but in the prior art by using a high hardness of 65 to 85 hardness itself, the impact strength is relatively strong for users possessing active athletic ability Strong, there is a problem inconvenient to wear due to high hardness.

Therefore, the present invention is to solve the above problems, while absorbing the impact due to the force applied to the ground while walking as much as possible to increase the resilience elasticity to promote walking, the local stimulation transfer is not shock on the heel The purpose is to provide a shoe that promotes kidney growth.

According to a feature of the present invention for achieving the above object, in the shoe provided with an insole forming the insole and the midsole forming the insole and the insole, is installed on the portion corresponding to the heel portion, according to the load Sponge with an ASK TYPE C hardness of 45 or less and 50% or more of resilient elasticity so that the resilient elasticity restored during shrinkage deformation and load removal is relatively faster than that of the midsole made of ethylene vinyl acetate or polyurethane. A midsole having a resilient elastic body made of a foam; And an insole having a magnetic pole member made of a growth point stimulus formed of a protrusion for stimulating the heel and a stimulating absorber for contracting and restoring according to a load applied thereto. Impact absorption occurs according to the contraction of the magnetic pole absorber and the resilient elastic body of the magnetic pole member according to the load, and the growth point stimulator stimulates the heel by the resilient elastic restoring force of the relatively repulsive elastic body during the removal of the load, thereby promoting the elongation growth. It is to provide a functional shoe for promoting kidney growth.

Preferably, the magnetic pole member comprises: a growth point stimulator formed of a protrusion; An elastic force of the spring, comprising: a lower support plate positioned below the growth point stimulator and supporting the growth point stimulator, a lower support plate positioned on the repulsive elastic body of the midsole, and a spring positioned between the upper and lower support plates By the contraction and restoration to be made by, or made of a synthetic resin material having a deformable, and an injection molding surrounding the outer surface; A growth point stimulator protruding through an upper surface of the injection molded product and formed in a protrusion shape; Located under the growth point stimulator, the gel material filling the inside of the injection molding; and made to shrink and restore by the deformability of the gel material. The growth point stimulator further comprises an insole protrusion protruding from the upper surface of the insole.

According to the present invention made as described above there is an advantage that can minimize the damage to the human body by the shock absorption according to the load, and help the kidney growth by stimulation by the resilient elasticity.

According to the present invention, the following effects are obtained.

As the growth point stimulator for kidney growth is stimulated by resilience by repulsive elasticity rather than by shock transfer due to load, renal growth without harm to human body, especially knee cartilage, does not harm the human body. There is an effect that can help.

In addition, the present invention exhibits the maximum impact absorption force according to the load is made even shock absorption, there is another effect that helps to walk by making a quick rebound elasticity.

Hereinafter, with reference to the drawings showing the shoe according to the present invention will be described in more detail. Figure 2 is a view according to one embodiment of the insole provided with a midsole and a magnetic pole member provided with a shock absorber of the shoe according to the present invention.

As shown, the present invention is structured across a midsole 10 commonly referred to as a midsole among insoles (outsoles, midsoles, insoles) and insoles 30 used as inner insoles in the shoe structure. That is, the present invention is based on the midsole 10 and insole 30, which are generally used in sneakers, running shoes, etc. in the structure of the shoe, and will be described below, the midsole 10 and the insole 30, respectively The overall function will be explained.

First, the midsole 10 will be described. In general, the midsole 10 is made of polyurethane or ethylene vinyl acetate, called pylon, in order to provide shape maintenance and proper shock absorption ability of the shoe. Typically, the midsole 10 has a main function of shock absorption according to walking, and thus, in the case of sneakers, running shoes, etc., is made of a sponge foam, and is made of appropriate hardness. The lower the hardness, the better the shock absorption, but has a problem of low resilience. That is, a pylon material is most commonly used as a material having a hardness of about 50 to 60 based on the ASC TYPE C hardness meter and having a repulsive elasticity of about 40 to 45%. If it is lower than the hardness, the rebound elasticity is lowered, and if it is higher than the hardness, the shock absorbing power is lowered. Therefore, the midsole used in the present invention is based on the use of a midsole of 50 to 60 as an ASKER TYPE C hardness meter.

Next, the resilient elastic body 20 is installed at a portion corresponding to the heel portion which helps the kidney growth in the midsole 10.

The repulsive elastic body 20 is made in the form of a sponge foam to form a deformation due to the force applied as a whole, when the applied force is removed, a plurality of spaces 20a to facilitate the original restoration force of the structure The formed structure is taken. The shape of the resilient elastic body 20 is easily contracted by the applied force when a force (vertical drag) is applied from the outside, but when such a force is removed, the original recovery force can be made faster by the action of the space portion 20a. Will be. In particular, the resilient elastic body 20 used in the present invention is deformed by a force faster than the midsole 10, the inherent impact absorption capacity and resilience of the midsole 10 will vary depending on the site. That is, in the case of the midsole 10 provided with the resilient elastic body 20, when a load is applied by walking, running, jumping, or the like, a specific portion of the heel provided with the resilient elastic body 20 is relatively midsole (10). By showing a shock absorbing ability faster than the material, and having a resilience due to the fast recovery force will have a different function than the other parts of the midsole (10).

That is, the basic condition of the resilient elastic body 20 required by the present invention should be less than 45 hardness measured by ASKER TYPE C durometer for faster shock absorption than the midsole, preferably 35 or less 45 because less than 35 If it becomes too soft to cause inconvenience in walking, if more than 45 can not exhibit sufficient shock absorption capacity. In order to have a fast rebound elasticity, it is preferable that the rebound elasticity is 50% or more, preferably 50% or more and 70% or less. Because less than 50% does not have a sufficient rebound elasticity effect, 70% or more can give a strain on the knees.
For reference, the hardness is measured using an Asker Type C hardness tester, and the resilient elastic force is measured using a resilience tester, and these values are widely used in the art. to be. Then, the resilient elastic force will be described in more detail. Resilience is the value measured along with hardness as needed for the outsole, midsole, or insole in the footwear industry.The definition is that the weight falls freely on specimens of any size (about 40 to 60 mm in diameter and about 4 to 7 mm in thickness). The electronic sensor measures the return height to the specimen and compares the peak position of the weight with the return height. The value is expressed in%. If it is 50%, it is half height, and if it is 100%, it is raised to the initial height with full elasticity. will be. The resilient elastic force is a standard test method (BS 903: PAB) is determined, the resilient elastic body according to the present invention also shows a value tested by the resilence tester (Resilence Tester) by the standard test method.
Therefore, the resilient elastic body according to the present invention is softer because the hardness is lower than that of the general midsole, and thus excellent shock absorption during load transfer prevents damage to knee cartilage, etc. It can stimulate your heels. This repulsive elasticity is the same principle that the stimulus is applied to the heel when performing skipping, jumping, and the like. This stimulus is transmitted through the heel to form a growth plate stimulus, which is the same as that which can usually be taller by known exercise. In other words, it is possible to prevent the damage to knee cartilage, etc. by better shock absorption than normal shoes, and to stimulate the heel more by fast and strong repulsive elasticity, which can help to promote kidney growth by growth plate stimulation. .
The reason for requiring such physical properties is that the present invention is not intended to help the growth of the growth by the impact of the applied load, but to minimize the damage to the human body by absorbing the impact as much as possible, giving local stimulation by the resilient elastic force that is restored to renal growth. To help. Therefore, as the resilient elastic body 20 according to the present invention has a faster shock absorbing ability and a faster rebound elastic force than the midsole 10, the heel portion in which the resilient elastic body 20 is installed is not an impact due to a load, but other resilient elasticity. Local stimulation is caused by, and this stimulus is to help the kidney growth.

Shrinkage deformation or restoring force due to the force of the repulsive elastic bodies 20 can be controlled by the size of the porous or sponge material of the sponge foam itself, these various forms of the resilient elastic bodies 20, such as shock absorbers or noise inhibitors Since the general technology is currently widely used for the purpose of the manufacturing process or features of such a resilient elastic body 20 will be omitted in the following detailed description. For example, the crosslinked foamed molded article shown in the Republic of Korea Patent Registration (Registration No .: 10-0482427) "crosslinked foamed molded article and the molding method in which the molding body and the internal cavity structure is integrally formed." The above patent sufficiently shows the physical properties of the semi-elastic elastomer 20 required by the present invention as a crosslinked foamed molded product. In other words, the physical properties shown in p15 is shown as the surface hardness is 37, the resilience is 55%. That is, since the hardness of the midsole 10 is softer than the hardness of 50 to 60, the shock absorbing force is more excellent, and the rebound elasticity also has a 55% greater than the midsole 10, so the required value of the repulsive elastic body 20 required by the present invention. Satisfied enough.

Next, the insole 30 will be described. Insole 30 in the present invention as a general insole 30 used in ordinary sneakers, etc., but the magnetic pole member 40 in the insole 30 of the upper portion of the portion where the resilient elastic body 20 of the midsole 10 is located To be provided.

The magnetic pole member 40 is composed of a growth point stimulator 42 and the magnetic pole absorber (44). Growth point stimulator 42 is in contact with a specific portion of the heel is a portion to make a stimulus is made of a protrusion form. As shown in FIG. 2, the growth point stimulator 42 is made of a rigid material rather than the insole 30, and is formed of a plurality of protrusions. The protrusion 42 may be inserted into the insole 30 to be closed to the heel when shrinkage deformation due to the load, but may be configured to protrude an end portion of the protrusion on the top surface of the insole 30.

Alternatively, it may be possible to have other protruding insoles 42a on the upper surface of the inner insertion protrusion 42 and the corresponding insole 30 as shown in FIG. 3. In this case, the inner protrusion 42 stimulates the insole protrusion 42a, and thus the insole protrusion 42a has a dual structure of stimulating the heel.

Next, the stimulation absorber 44 will be described. The magnetic pole absorber 44 has a structure that contracts and restores according to a load applied to the lower surface of the growth point magnetic pole body 42. As shown in Figs. 2 and 3, the magnetic pole absorber 44 basically has a structure composed of a spring 44c which is easily deformable by force. That is, a spring 44c connected to the growth point magnetic pole body 42 is installed between the bottom support plate 44a for the fixed support of the spring 44c and the top support plate 44b supporting the growth point magnetic pole body 42 on the bottom surface. It becomes the structure that becomes. Therefore, the impact due to the force transmitted when the load is applied by the heel is absorbed by the contraction of the spring 44c of the magnetic pole member 40, when the load is removed by the elastic restoring force of the spring 44c The growth point stimulator 42 is intended to stimulate the heel portion. Of course, although the growth point stimulus 42 of the heel portion during the load transfer stimulates some, shock absorption due to the contraction of the spring 44c is given priority over the stimulus as a whole, and the promotion of extension growth by the heel stimulation is described above. The repulsive elastic body 20 of the midsole 10 is combined, the stimulus due to the elastic restoring force is mainly acted.

Next will be described another embodiment according to the present invention. 4 shows another embodiment of the magnetic pole member 40 'and shows a case where the magnetic pole absorber 44' is filled with a gel material. That is, the growth point stimulus 42 'is basically provided, and the growth point stimulus 42' is positioned above the gel material 44 'filled in the injection molding 46. Therefore, in this case, the injection molding 46 surrounding the outside is made of a film-like material having a certain degree of deformability due to the applied force, thereby transmitting the gel material upon the force acting on the upper surface of the growth point stimulator 42 '. Shock absorption by 44 'can be achieved. When such a gel material 44 'is filled inside, there is an advantage in that an appropriate response can be made to a small force change. In other words, when walking or running in shoes, analyzing the pattern of force, the sequential transmission of force occurs from the outside of the heel to the inside and forward. Therefore, when the gel material 44 'is filled, the growth point stimulator may respond to each other in accordance with the position and strength according to the delivered force, so that the shock absorbing ability or the restoring force may be more effectively coped.

In the above description, the stimulation absorbers 44 and 44 'are described as springs or gel materials, but are not limited thereto. In other words, it is sufficient to absorb a given load and have a resilience restoring force, so that a shock absorbing force is faster than a conventional insole, and a faster rebound elasticity will be sufficient. As an example of such a material it is possible to form a variety of sponge foam, such as a polyurethane foam, Y-A foam, a silicone foam is a physical property control.

Next, the process of delivering the stimulation for promoting kidney growth in the shoe provided with the midsole 10 and the insole 30 according to the present invention configured as described above will be described.

As described above, the basic function to be provided in the shoe is the assistance of walking by the protection of the human body by the shock absorbing power and the resilience elasticity. However, the stimulation for kidney growth should literally give a local stimulus to the heel, the conventional shoe structure was approached in the opposite concept of shock absorption by allowing excessive shock transfer to the heel. This helps the growth of the kidney, but in order to cause damage to the knee cartilage, etc. in the present invention, in order to facilitate the growth of the kidney by the stimulation due to the resilience of the resilience rather than the shock transmitted by the load to inherent It is aimed at helping kidney growth while utilizing shock absorption and resilience.

Looking at the process, first, when the load is applied in the process of the force of the walk forward through the heel portion, the load is through the midsole 10 and the outsole (not shown) through the insole 30 in contact with the sole surface Ground reactions are made. Since the force received by the human body receives the shock caused by the repulsive force between the sole surface and the ground, the damage to the human body is determined depending on how much shock absorption or dispersion is performed in the intermediate vehicle.

Therefore, the insole 30 and the midsole 10 are generally installed in consideration of the maximum impact absorbing power, in particular, considering the impact concentrated on the heel, the resilience should be sufficiently considered.

In the present invention, when the load is transmitted, the insole 30 is transmitted to the midsole 10 through the insole 30 and the midsole 10 exerts a shock absorbing force as well as the load transmitted to the magnetic pole member 40 is stimulated It is transmitted to the absorbers (44, 44 '), and thus the stimulus absorber (44.44') is absorbed by the stimulus is contracted, and this load is also transmitted to the resilient elastic body 20 of the midsole (10) to absorb shock Is done. Therefore, in the heel portion where the most shock is transmitted during load transfer, the shock absorbing power by the stimulation absorbers 44 and 44 'and the resilient elastic body 20 is increased, so that sufficient shock absorption can be achieved, thereby minimizing the effect on the human body. Will be.

Next, when the heel load is moved to the front part, the resilient elastic body 20 and the magnetic pole absorber 44 and 44 'have elastic restoring force, and the elastic restoring force is the midsole 10 and the insole 30. Branches are made at a much faster rate than elastic resilience. Therefore, the heel of the sole as the resilient elastic force of the resilient elastic body 20 having the fastest elastic restoring force and the next magnetic pole absorber 44,44 'is made faster than the midsole 10 and the insole 30. In this part, the growth point stimulus 42 delivers a stimulus, not a shock, to the heel. That is, the stimulus due to the elastic restoring force is applied to the heel rather than the stimulus due to the applied load, and thus a certain amount of stimulus transmission is achieved, and the stimulus transfer can help the kidney growth by being transmitted to the growth plate of the knee. That is, in the conventional shoes, but not accompanied by damage to the knee cartilage and help the kidney growth due to the transmission of the stimulation by the shock and the shock absorbing force due to the shock at the same time, in the present invention, there is no damage to the human body by the shock absorbing power at all Of course, by increasing the resilience elasticity to help walking, as well as heel stimulation can be performed at the same time can help the kidney growth.

In order to examine whether the functions shown in the present invention are sufficiently performed, the feasibility was examined by performing the following experiment.

FIG. 5 is a measured value and a pictorial value obtained by experimenting with foot pressure and dispersion by the midsole, and FIG. 6 is a graph showing numerical results of walking by foot over the entire sole of the foot.

As shown, Figures 5 and 6 show only the case of the midsole. 5A and 6A show a case of a midsole equipped with a resilient elastic body according to the present invention, and FIGS. 5B and 6B show a case of a general midsole.

FIG. 5 is measured using a Pedar Cable product of Novel, Germany, and FIG. 6 is measured using Zebris, a treadmill system for gait analysis, which is widely used for shoe pressure and dispersion measurement.

As shown in Fig. 5, MO1 represents a posterior foot pressure, MO2 represents a midfoot pressure, and MO3 represents a forefoot pressure. In the figure, the pressure increases from black to red. The midsole of the present invention in which the repulsive elastic body of FIG. 5A was inserted showed better pressure relief and pressure dispersion in all areas of MO1 to MO3 than the general midsole of FIG. 5B and was numerically superior. In particular, it can be seen that MO1, which is a posterior foot region, is more excellent. That is, it can be seen that the resilient elastic body exhibits a certain amount of shock absorbing force in the midsole, thereby exhibiting even shock absorbing ability throughout the entire portion, thereby suppressing damage to the human body as much as possible.

On the other hand, as shown in Figure 6, when looking at the walking analysis graph by the treadmill wearing a shoe wearing a midsole provided with an insole and a resilient elastic body and a general shoe and a midsole provided with a stimulating member according to the present invention, The difference between the two is clearly shown.

In other words, the hill strike area is the area where the foot (shoe) touches the ground during walking. Excessive pressure concentration on this area will cause damage to the human body, and the toe area should be as low as possible. (Shoes) represents the area of resilient elasticity that kicks out of the ground. Too low a value causes walking discomfort.

Analyzing the graph of the quantum shoes, it can be seen that the present invention shown in Figure 6a exhibits a uniform pressure distribution as a whole exhibits a shock-absorbing power and even distribution. Looking at the numerical values, the deviations range from 15 to 22 over the entire walk. On the contrary, the general shoes shown in FIG. 6B have deviations from 20 to 33. That is, in the present invention, the default value of the shock absorbing power is excellent in the shock absorbing ability by 20 in 15 general shoes, and the maximum value of 30 appears in the normal shoes. On the other hand, as shown in the inclination of the graph showing the even distribution of the impact, the present invention shows a uniform dispersion, while in normal shoes the deviation is too large, it can be seen that the impact according to the load is transmitted as it is.

Let's look at the repulsive elastic part. In the present invention, when moving from the hill strike part to which the initial load is transmitted to the tow area where the load transfer is reduced, the original recovery by the resilient elasticity occurs while walking about 25% to 15 parts, which is the lowest point of excellent shock absorbing power. In ordinary shoes, up to about 45% of progression is smooth. That is, in other words, in the present invention, it exhibits rapid rebound elasticity, which leads to the conclusion that the growth point stimulator may stimulate the heel portion. On the other hand, as shown in the tow, it can be seen that the shoes according to the present invention is more effective than the ordinary shoes when the walking force due to the fast rebound elasticity.

As shown in the experimental results of FIG. 5 and FIG. 6, in the present invention, it can be seen that the shock absorbing force is increased as well as fast rebound elasticity. Accordingly, the growth point stimulator sufficiently stimulates the heel to help the kidney growth. Of course, it can be seen that it is possible to suppress the damage to the human body as much as possible by inducing even distribution of the impact.

As described above, in the present invention, the shock absorbing force according to the applied load is maximally exerted, induces even pressure distribution, provides resilient elastic force to the maximum, thereby heel stimulation, thereby helping kidney growth. As such, it will be apparent that various forms required by the present invention can be made without specifically indicating all cases in the embodiments.
