JP4521689B2 - Walking assist shoes for the disabled - Google Patents

Description

  The present invention is an improvement of shoes dedicated to walking aids for disabled people that are suitable for use by disabled people and physically disabled people who are physically disabled.

Conventional shoes used by ordinary people mainly focus on the appearance of the shoes to fit the feet more and make the feet look more beautiful, but to protect the feet more firmly than ordinary shoes. As a thing, there is a protective shoe for work in which a core material such as a steel plate is arranged on the back of a shoe upper.
There are also shoes that protect the periphery of the bag with a core material such as a steel plate.

By the way, a physically handicapped person who has a disability in his / her body starts with rehabilitation walking practice at a hospital or at home to recover his walking ability.
However, at that time, there is anxiety about carrying a foot that supports his / her own weight, and many disabled persons tend to put on their weights with their ankles bent outward, so-called sprains.

For this reason, walking is also cautious, and power tends to be applied to strange parts of the body.
On the other hand, shoes such as shoes for the general public and sneakers that are kind to the feet are more likely to sprain, and such things as the protective shoes mentioned above are heavy and cannot be used.

In addition, when a person with a disability wears or removes shoes, a part of the instep of the instep of the shoe is opened and closed using, for example, Velcro (registered trademark) or the like so that the operation is easy. There is a type of footwear having an upper that can be bent outwardly of both feet, which facilitates the attachment and detachment of shoes.
Therefore, when the inventor investigated the prior application, there was hardly any thing close to the present invention, and the following three cases were only approximate.

  First of all, for the purpose of mitigating tripping during exercise and mitigating the impact on the foot, the upper surface of the foot flat plate to be installed between the athletic shoe cover and the interior is provided with a convex, A movable plate that provides an auxiliary plate (possibly acting as a cushion) in the lower part of the foot back plate and facilitates the bending and stretching movement of the foot to a height of 1/3 from the lower part around the area where the heel of the foot back plate hits There is a name “injury prevention device for athletic shoes” in which the sprain prevention plate having (difficulty to understand) is erected in order to fix it to the leg from the athletic shoe cover. (For example, refer to Patent Document 1).

  Next, the inventor of the present invention invented the main part of the ankle holding surface standing so as to cover the area of the ankle, and the insole of the insole refracted in an L shape from the lower side. A sprain prevention member consisting of a fixing surface that is long enough to cross the arm is disposed around the outer ankle under the ankle, and the upper part of the outer cover (upper) is connected to the outer side surface part on both sides. The name of the invention “ankle sprain prevention shoe” is provided with a fastener for separating and opening to the vicinity of the hem tape or the hooking tape. (For example, refer to Patent Document 2).

Further, for the same purpose as the above invented by the inventor of the present invention, the main point is that the outsole of the shoe is an outsole having a large overhanging portion in the outer side direction, It consists of an outsole and an outsole with a hard plate in the direction crossing the outsole, and the instep part of the outsole (top) is separated and opened to the side of the side of the side and the toe cap. It is the name of the invention “ankle sprain prevention shoe” provided with a zipper. (For example, refer to Patent Document 3).
JP 2000-245501 A ([0005] to [0006], FIGS. 1 to 2) JP 2001-286302 A ([0011] to [0016], FIGS. 2 to 4) JP 2001-286303 A ([0011] to [0015], FIGS. 1 to 4)

In the above-mentioned Patent Document 1, a sprain prevention plate is erected in the area where the heel of the foot plate hits, so that it may be possible to prevent the foot from tilting somewhat, but on the other hand, it assists the cushion function in the part where the foot is stepped on Since the board is provided, it is thought that the tension does not work and the tilt prevention force is hindered. Furthermore, there is a dislike of being too weak to support a sprain prevention board with the material of a normal athletic shoe cover and interior.
It is difficult to understand the reason for the existence of the movable plate that facilitates the bending and stretching movements of the foot.

  Patent Document 2 is an application by the present inventor, and a sprain prevention member refracted into a L-shaped cross section, which is a main part at the time of commercialization, is provided on the insole of the shoe from the ankle side as a fixing surface. However, it is necessary to cut the incision part on the back of the insole because it is about the same length as the insertion of the fixing surface. There is a disadvantage that a half-finished product generated by the cutting is wasted.

Moreover, since the cutting operation and the fixing operation itself with an adhesive increase the manufacturing cost rather than such a drawback, for example, the fixing surface is integrally formed with the outsole at the time of manufacturing the outsole so that these operations can be omitted. For example, we want to greatly simplify the manufacturing process.
However, the anti-spraining member with the fixing surface is a large one that is refracted into an L-shaped cross section. Therefore, the design of the integral molding die is unreasonable and cannot be performed easily.

Further, the ankle holding surface itself of the sprain prevention member should be able to be replaced with the most suitable one according to the actual condition of the user's obstacle with respect to its shape, length, and the like.
That is, it is much more convenient for the user to prepare several different ankle holding surfaces even if the shoes are the same so that they can be exchanged when necessary.

In addition, in the upper part of the instep, a zipper was provided to separate and open the front and rear side parts on both sides and close to the hoxing tape. It turned out that this act itself was not easy by pulling the zipper.
Therefore, we would like to change this method to other means.

  Patent Document 3 is also an application by the present inventor, and the prior application by a third party was completely zero because of the specificity of the shape. Certainly, the presence effect of the overhanging portion is large, but it can be said that it is preferable to add the ankle holding surface of Patent Document 2 in order to enhance the effect. In other words, the inventor wants to combine Patent Document 2 and Patent Document 3.

  In addition, the upper part of the upper part of Patent Document 3 is also provided with a fastener for separating and opening up to the vicinity of the front side surface part and the toe cap on both sides, but in order to actually perform this opening and closing action, It turned out to bend deeply and pull the zipper towards the toe, which proved difficult. Therefore, I would like to change this method to other means.

  As described in detail above, the object of the present invention is to merge the advantages of Patent Document 2 and Patent Document 3, and to obtain an effect more than the merger of both.

The structure of the present invention will be described below with reference to the drawings. In these drawings, the same reference numerals are used to designate the same functional elements even if the shapes are slightly different.
In addition, the lead lines are not necessarily provided at all locations to which the same reference numerals are attached, and some of them are representatively selected.
Furthermore, both the shoe of the present invention and the other shoe have one foot, and with the one foot aligned, the description is distinguished from the disabled foot side and the healthy foot side, and one of them. The left and right directions of the shoes were also distinguished by referring to the left side of the left shoe as the outside and the right side as the inside, the left side of the right shoe as the inside and the right side as the outside. Also, the vertical distinction is the same.

By the way, in the shoe manufacturing industry, there are various names used for shoe parts and materials, and here they will be described in general terms but will be described here.
The one shown at the top is adopted for all, and the latter is often used in the field.
Outsole; Outsole, Outer, Cover: Outer heel / Tail surface / Upper, Feather: Wing, Insole: Middle / Insole / Texon, etc.

In general, leather, synthetic leather, synthetic resin, rubber, cloth, hemp, etc. are used as the sole material of shoes. In the sole 1, which is adopted in the present invention, a polyurethane-based synthetic material that can be injection-molded. There are resin (hereinafter referred to as PU material), thermoplastic rubber (hereinafter referred to as TPR material), PVC (vinyl chloride resin), etc., and PU material was used as the main subject of explanation. The material used for the upper is leather, synthetic leather, synthetic resin, rubber, polyurethane-based material, nylon-based material, cotton, hemp, material, etc., but the upper 11 blade 12 employed in the present invention. As the material for the blade stopper 13 and the like, polyurethane synthetic leather (hereinafter referred to as “PU material”) was used as an explanation subject.
Therefore, the present invention is not limited by the difference in materials of these shoes.

As shown in FIGS. 1 and 2, in shoes having a protruding portion 2 in the outward direction of the outsole 1, as shown in FIGS. 6 and 10 , the outsole 1 is almost traversed with an ankle-like width. There is an outsole reinforcing plate 3 that is inherently present, and an overhanging portion reinforcing plate 4 that is present over substantially the entire region of the overhanging portion 2 or covers the upper surface. In addition, it is assumed that having ankle holding member 5 for covering the ankle around as shown in FIGS. 4 and 8.
And this heel holding member 5 is formed by connecting the outsole reinforcing plate 3 and the overhanging portion reinforcing plate 4 in an inverted T-shaped cross section. Shoes.

As shown in FIG. 5 , first of all, the connecting means of the bottom bottom reinforcing plate 3, the overhanging portion reinforcing plate 4 and the heel holding member 5 is one of the preferable means as shown in FIG. It is assumed that the partial reinforcing plates 4 are connected on the same plane. Then, it is assumed that the heel holding portion connecting member 6 is provided on the upper surface of the surface bottom reinforcing plate 3 exposed from the shoe, that is, on the upper surface of the boundary between the surface bottom reinforcing plate 3 and the overhanging portion reinforcing plate 4. That is, the heel holding member 5 as shown in FIG. 4 is formed in a reverse T-shaped cross section so as to be detachable on the series of outsole reinforcing plates 3 and overhanging reinforcing plates 4 via the heel holding portion connecting members 6. It is erected.

Other coupling means, and that the overhanging portion reinforcing plate 4 and the ankle holding member 5 is integrated in an L-shaped cross section as shown in FIG.
Then, as shown in FIG. 9 , a heel holding portion connecting member 6 is provided on one end side exposed from the shoe of the outsole reinforcing plate 3, and the one end side portion of the heel holding portion connecting member 6 is integrated with the above. Further, the refracting side 7 having an L-shaped cross section is brought into contact with each other, and both are connected by an appropriate coupling means.
In addition, the attachment means to the front-and-bottom reinforcement board 3 of this heel holding | maintenance part connection member 6 may be welded or screwed together with the above-mentioned thing. Moreover, the overhang | projection part reinforcement board 4 in this structure is affixed on the upper surface of the overhang | projection part 2 with a strong adhesive agent.

Furthermore, the outsole reinforcing plate 3, and that has a large number of through holes 8 as shown in FIGS. 5 and 9, as seen in dotted lines in FIG. 6 and FIG. 10, and made the outsole 1 synthetic resin After the injection, that is, the injection molding is performed at the time of manufacturing the outer bottom 1, the resin is integrally cured through the many through-holes 8, and the fixation of the outer bottom reinforcing plate 3 and the outer bottom 1 is strengthened. is there.

In addition, as shown in FIG. 5 , the overhanging portion reinforcing plate 4 connected to the top bottom reinforcing plate 3 on the same plane is integrally formed in the same manner. 8 is assumed to have.
Furthermore, the binding of the ankle holding member 5 and the ankle holding part connecting member 6 has been described above with linking at Naru suitable coupling means, as seen in FIGS. 4 and 8, the refractive edge 7 of the ankle holding member 5 the clearance hole 9 of appropriate number of the ankle holding part connecting member 6 provided with a clearance hole 9 and at least as many female screw 10 of FIG. 1 both at screws 19 as seen in FIGS. 2 and 12 It is configured to be detachably coupled.
In addition, since various structures can be considered for the specific shape of the heel holding portion connecting member 6, refer to the following embodiments.

Of course, there are various conventional methods for the coupling means of both, so any coupling means may be used. However, the product of the present invention is not frequently exchanged, and the mounting itself is desired to be solid. I want to use screws 19 for the screws.
In addition, depending on the contents of the disability of the handicapped person, a thing as shown in FIG. 12 in which the heel holding member 5 is extended upward so as to follow the leg shin is also necessary. In this case, it is preferable to arrange several types of heel holding members 5 having different lengths.

Although the shoes for the normal foot side are shown in FIG. 3 according to the type of shoes for explaining the present invention, as shown in FIGS. The left and right shoes are directed toward the inside of the shoe as the direction of refraction when closing.
In the opening and closing means for closing and closing, a tape (trade name “magic tape” or “Velcro”) that presses the two together is sewn to the back surface of the blade stopper 13 and a part of the blade 12 that is opposite to the tape. deep.

  By the way, in the shoe on the healthy foot side in FIG. 3, the finger insertion ring 23 for separating the wing retainer 13 from a part of the wing 12 is on the near side on the inside of both feet, and the shoe in FIG. Since the shoe is placed in front, the closing direction of the blade 13 is closed in the inner direction of both feet and opened from the inner side to the outer side.

  In addition, as shown in FIG. 1 and FIG. 2, these two wings 12 are inclined so as to follow the contour of the wing 12 from the vicinity of the toe of one wing 12 in the length direction of the shoe. The pull-up loop band 14 is provided in the shape of the other blade 12 around the mouth.

  When walking with the shoes of the present invention, even if the weight is applied with a heel with the ankle bent outward, there is an overhanging portion 2 in the outward direction of the outsole 1, and the outsole 1 Since the bottom reinforcing plate 3 is integrated and integrated, and the overhanging portion reinforcing plate 4 is embedded or stuck on the overhanging portion 2 on the same plane, the width of the outsole is widened. 1 itself does not turn easily.

  In addition, since the heel holding member 5 is erected vertically to the overhanging portion reinforcing plate 4, the effect of preventing the ankle from bending outward is further enhanced. Therefore, since it becomes difficult for the shoes to tilt outward, the angle of the ankle is naturally corrected to prevent falls and sprains, walking anxiety is resolved, Because it doesn't give power to strange places, people with disabilities can feel confident in walking.

  Also, since the bottom bottom reinforcing plate 3 part and the heel holding member 5 can be separated, the integral injection molding becomes possible, so that the manufacturing cost can be greatly reduced, and the bottom bottom reinforcing plate 3 had a large number of through-holes 8, the resin at the time of injection molding was cured through the through-holes 8, and the fixation of the outsole reinforcing plate 3 and the outsole 1 was reinforced.

  In addition, by making the bottom bottom reinforcing plate 3 part and the heel holding member 5 separable, depending on the disability contents of the handicapped person, the heel holding member 5 is extended so as to follow the leg, etc. The most suitable one can be selected and used from the heel holding member 5.

In addition, two new means have been invented in order to facilitate attachment and detachment when a disabled person puts on and takes off shoes. First, a pull-up loop band 14 is provided from the vicinity of the toe of one blade 12 over the mouth of the other blade 12 so as to hang along the contour of the blade 12 in the length direction of the shoe. That is.
This is because when a person with a physical disability lifts or removes a shoe, he first lifts the disabled leg up to the healthy knee with one hand without an obstacle, but this requires considerable force. is there.

For example, in general, a person with a disability on the right is often disabled on the right limb. Therefore, in the case of taking off the shoes, the shoes on the right foot of the heel that was worn in the past are lifted so as to hold the right ankle with only the left hand without any obstacles and carried to the left foot or above the knee. Because it was, it was not easy.
Therefore, by providing the pull-up loop band 14 that is easy to grip, it can be easily lifted even with one hand.

Secondly, the wing retainer 13 for overlapping and securing both wings 12 of the upper 11 is closed toward the inner side of the shoe as the refractive direction of both the left and right shoes.
Also in this case, if the right foot is inconvenient, only the left hand becomes the dominant hand, so the action of the wing 13 of the right shoe for obstacles is performed with the left hand, rather than pulling from the left to the right outside, It is easier to pull from the left to the left. If the left foot is inconvenient, the opposite is true, and in all cases it was easier to move toward the inside of the shoe and it was actually very popular.

Even if it is the best mode for carrying out the present invention, it is somewhat different depending on the type of shoes, so here it is described as sneaker-style shoes.
First, the outsole 1 and the overhang portion 2 employ a material that can be injection injection molded, such as a PU material, TPR, or PVC. Then, the outsole reinforcing plate 3 that is substantially transversely integrated with the width of the ankle in the outsole 1 and the overhanging portion reinforcing plate 4 that is integrated over almost the entire region of the overhanging portion 2 are coplanar. As the body, an iron plate having a thickness of about 2 mm in which a large number of through-holes 8 are previously drilled in both is adopted.

Further, a plurality of heel holding members 5 are detachably erected on the upper surface of the bottom bottom reinforcing plate 3 exposed from the shoes, that is, on the upper surface near the boundary between the top bottom reinforcing plate 3 and the overhanging portion reinforcing plate 4. The heel holding part connecting member 6 having the female screws 10 arranged in parallel is made as shown in FIG .
Na us, 20 is the refractive edge portion is refracted extend upwardly for preventing leakage between stationary.

In order to integrate them, the injection molding is carried out to form the outsole 1 having the overhanging portion 2 of the present invention. However, the injection molding mold is preliminarily made light so that the outsole 1 itself is also lightened. also in order to save material, it is preferable to considerations such as to make produce multiple recessed outsole of the hole 21 as shown in FIGS. 6 and 10.

As shown in FIG. 4 , the heel holding member 5 also employs an iron plate having a thickness of about 2 mm, and has a plurality of fool holes 9 corresponding to the female screws 10 that match the fool holes 9 of the heel holding portion connecting member 6. , the outer and ankle protection bending portion 17 of the ankle holding member 5, forms a refractive edges 7 by pressing on it, preferably rather want to consider the press die that allows stamping molding in one pressing.

At that time, the parallel arrangement interval of the hole 9 of the hook holding member 5 and the female screw 10 of the hook holding part connecting member 6 is narrowed, and the number of the hole 10 or the female screw 10, that is, either one of them. It is desirable to increase the number of the heel holding member connecting member 6 with respect to the heel holding portion connecting member 6 so that the attachment / detachment position of the heel holding member 5 can be slightly adjusted in the front-rear direction of the shoe.
In addition, cheap and strong iron plates and steel shapes are used as the material of the heel holding member 5, the heel holding portion connecting member 6, the outsole reinforcing plate 3, and the overhanging portion reinforcing plate 4, but it is expensive but lightweight and strong. It can be said that it is more preferable if other metal materials such as duralumin, carbon materials, or reinforced plastic materials containing glass fibers can be adopted.

Then, a fool of the scissors holding member 5 obtained by press working into 9 rows of staggered holes which are 10 rows of female threads of the scissor holding portion connecting member 6 exposing one side portion on the outside of the bottom 1 obtained by injection molding. The holes 9 are assigned and tightened with screws 19 such as bolts. The bolt used at that time is preferably of the type that is screwed with a hexagon wrench only in a narrow space.

The long heel holding member 5 as shown in FIG. 12 (in which the overhanging portion reinforcing plate 4 is stuck on the overhanging portion 2) becomes heavy because it becomes heavy, but it is expensive but is made of carbon material or glass fiber. The reinforced plastic material may be used. If you use an iron plate, you should cover it with neoprene material in consideration of the coldness of winter use. Of course, it is assumed that a band 16 is provided at an appropriate position of the long heel holding member 5 so as to be fixed to the shin. Of course, the length of the heel holding member 5 may be several types according to the contents of the obstacle of the user.

Now, the material of the upper 11 and its blades 12 is a so-called PU synthetic leather that employs PU material, and is joined to the bottom 1 that is the so-called PU bottom with an adhesive at the lower side. Of course, an insole, an insole, etc. are necessary as shoes, but the description is omitted because they are not related to the present invention.
Note that a blade stopper 13 is provided on one of the blades 12, but a U-shaped belt body 22, which is a PU material sewn with a ring-shaped nylon tape 23 into which a finger is inserted, is connected to the blade 12 through an elliptical eyelet 18. It shall be fastened to the back of the.

  Further, a tape (trade name) that presses and joins both commercially available products to the back side of the straight portion around the center of the U-shaped belt body 22 and the other blade 12 corresponding to the straight portion. "Magic tape" or "Velcro").

  The pulling loop band 14 is made of a tough nylon material and is suitable over the mouth of the other wing 12 so as to be hooked diagonally from the vicinity of the toe of the wing 12 in the length direction of the shoe. Although it is sewn with a space, the strongest part of the blade 12, that is, as shown in FIGS. 1 and 2, the outline of the blade 12 that is thin and thick as an edge winding It is better to sew on the part.

Explaining Example 1 as a sneaker-style shoe, FIGS. 1 and 2 show the right shoe for the right handicapped person and the left shoe for normal use shown in FIG. However, in both figures, the overhanging portion reinforcing plate 4 should be viewed as being invisible in the overhanging portion 2.
First, the outsole 1 which is a common embodiment will be described. In FIG. 1 and FIG. 2, PU material is adopted, the entire length of the outsole 1 is 250 mm, the width of the upper part is 98 mm, and the overhanging part 2 is provided. In the example in which the width of the narrowest edge portion is 75 mm, the length of the overhang portion 2 is 140 mm, and the arc shape has a width of 50 mm.

Further, there is an edge height portion 24 around the entire circumference of the outsole 1 shown in FIG. 6, and as seen from the side surface of FIG. 7 , the height of the edge height portion 24 around the heel holding portion connecting member 6 is 29 mm. Although the upper surface of the heel holding portion connecting member 6 is drawn lower as shown by the dotted line, this height is slightly different from the level of this figure depending on the embodiments to be described later.

  Of course, since the outsole reinforcing plate 3 and the overhanging portion reinforcing plate 4 are buried in the PU material of the outsole 1, the top surfaces of the outsole reinforcing plate 3 and the overhanging portion reinforcing plate 4 are edge height portions. The height of 24 is much lower than 29 mm. Incidentally, the height (thickness) around the hole 21 in the bottom 1 is about 9 mm and about the half of the height of the edge height portion 24.

Now, the bottom bottom reinforcing plate 3 and the overhanging portion reinforcing plate 4 shown in FIG. 5 employ a steel plate having a thickness of 2 mm with through holes 8 drilled at appropriate locations, and the length of the bottom bottom reinforcing plate 3 is 90 mm. as width 55mm parts to be buried in the PU material and shall refractive sides 20 provided at a height of about 2mm toward the one side upward as seen in FIG.
Incidentally, the projecting portion reinforcing plate 4, as shown by the dotted line in FIG. 6, but is obtained by pressing cut to shape nearly the size of the overhang portion 2, the outer shape is similar to FIG. 6 There is no need.

  This refracting side portion 20 is for the purpose of improving stability during injection molding and preventing slipping off. The reason for facing upward is that if it is provided downward, the shoe will be worn out and the back of the bottom 1 will be worn out. This is because the refracting side portion 20 is exposed first when it is touched, and thus it is difficult to touch the hard ground and become slippery. The refracting side portion 20 is not necessarily necessary because the bottom bottom reinforcing plate 3 is fixed due to the presence of a large number of through holes 8.

Next, the heel holding member 5, which is a common embodiment, has a height up to the vicinity of the ankle and a width of about 90 mm, which is substantially matched to the heel holding portion connecting member 6, and an ankle protective curve that curves outwardly around the ankle. It has a portion 17 and is made of a 2 mm thick iron plate having a refracted side 7 with a fool hole 9 for fitting with the female screw 10 of the collar holding portion connecting member 6.
And it attaches with the volt | bolt which is the screws 19 screwed in from the outer side of the upper 11 with a hexagon wrench.

Although the heel holding member 5 is made of an iron plate, for example, a sock-shaped bag body part containing neoprene material or sponge material which is substantially the same shape as the heel holding member 5 is covered with PU material from the top to the bottom. It is good to take measures.
As a result, even if you touch the ankle or heel part in winter, you can prevent the cold feeling, and the disabled person loses the posture, and even if an unexpected force is applied to the heel holding member 5 on the ankle or heel part, you feel pain. So that you can get a sense of security.

Figure shows the ankle holding part connecting member 6 is omitted, which employs a U-shaped cross section of the channel steel, the width and height of about 15 mm, the length was approximately 90mm Similar the Table bottom reinforcing plate 3, On one surface of the channel steel facing the outside of the shoe, at least four fool holes 9 corresponding to the fool holes 9 of the heel holding member 5 are drilled. Then, a commercially available nut is provided as a female screw 10 in each of the fool holes 9 on the surface facing the inside of the shoe by electric spot welding.
In addition, the lower surface of the channel steel is fixed to the boundary between the outsole reinforcing plate 3 and the overhanging reinforcing plate 4 by electric spot welding.

In order to prevent the PU material from entering the female screw 10 at the time of injection molding, a cover such as a single tin plate, for example, needs to be provided on the front surface of the female screw 10 row.
In this case, although not shown in the drawings, it is desirable to make a long hexagonal cylindrical cover that matches the outer shape of a commercially available nut, and cover each nut.
The reason for making this cylindrical cover longer is that the bolts, which are the screws 19 to be screwed, are longer than the nuts.

The hook holding part connecting member 6 of Example 2 (not shown) adopts the same channel steel as that of Example 1 and has a width and height of about 15 mm and a length of about 90 mm, which is similar to the outsole reinforcing plate 3. It was.
Then, four short square members 25 having a size that fits within the U-shape of the channel steel and screwed with the female screw 10 are subjected to electric spot welding at a designated position.
Of course, in this case as well, in order to prevent the PU material from entering the female screw 10 at the time of injection molding, it is necessary to provide a single tin cover (not shown) on the inner surface of the shoe.

Next, the heel holding part connecting member 6 of Example 3 will be described. This is an angle steel with an L-shaped cross section (not shown) , and the size thereof is the same as in the case of the groove steels of Example 1 and Example 2, so that the description of dimensions is omitted.
This Example 3 is an example in which the most weight reduction is aimed at as the heel holding portion connecting member 6. However, this is also because exposed considering that at the time of injection molding, it is necessary to provide a cover such as manufactured by blanking Riki in front of the female screw 10 columns.

However, problems are likely to occur when used for a long time. That is, the upper side portion of the angle steel has a refracted side 7 in the heel holding member 5 even though the width is narrow, so there is no particular problem in the connection of the heel holding member 5, but if it is worn for a long time as a shoe, of even cover it had been subjected, in the human body weight come at the outsole 1 is depressed, the nut and the female screw 10, which may damage the foot so sole hits the screws 19 It is. On the other hand, if channel steel is adopted, there is a flat part on the upper side, so there is no worry of damaging the sole even if it is worn for a long time and dents.

Furthermore, the heel holding part connecting member 6 of Example 4 will be described with reference to FIG . This is a square material just iron, width 18 mm, thickness 10 mm, the length and 90mm Similar the Table bottom reinforcing plate 3, parallel to the female screw 10 which is a blind hole which does not four through toward the outer shoe Set up. The upper surface is provided with four holes 15 at positions avoiding the female screw 10 for weight reduction.
In the fourth embodiment, since the length of the female screw 10 is about 15 mm and is not penetrated, a cover or the like for preventing the PU material from entering is unnecessary. Naturally, the bolt used as the screws 19 has a total length of 15 mm or less.

In Example 5, as shown in FIG. 9 , the overhanging portion reinforcing plate 4 was separated from the outsole reinforcing plate 3 on the assumption that the heel holding member 5 and the overhanging portion reinforcing plate 4 were integrated into an L-shaped cross section. However, since the others are the same as those of the first embodiment, description of dimensions and the like is omitted.
However, as described above, the overhanging portion reinforcing plate 4 is adhered to the upper surface of the overhanging portion 2 with a strong adhesive, and FIGS. 8 to 10 relate to the fifth embodiment.

Example 6 is shown in FIG. 12 , and the heel holding member 5 is extended long upward along the shin of the leg. The illustrated example has an overall height of 300 mm, and is provided with a band 16 for turning around and attaching to a leg at two points in the middle. In FIG. 12 , the overhanging portion reinforcing plate 4 is illustrated as being attached to the overhanging portion 2. However, if the overhanging portion reinforcing plate 4 is embedded in the overhanging portion 2, the overhanging portion reinforcing plate 4 cannot be seen. It goes without saying that it is good.

Further, it is sufficient if the heel holding member 5 is made of expensive carbon, but if it is made of an iron plate, it is cold in winter, so that it is necessary to take measures to cover it with a neoprene sack, for example.
Further, it is desired to select the heel holding member 5 having a length of 140 mm so that it can be selected depending on the degree of disability.
In addition, since the Example of the pulling-up loop belt | band | zone 14 and the blade stopper 13 was explained in full detail in the term of the best form for implementing this invention, description is abbreviate | omitted.

It is a perspective view of the Example of this invention. (Example 1 and Example 5) It is a top view of FIG. (Example 1 and Example 5) FIG. 3 is a perspective view of a shoe worn on a healthy foot. It is a perspective view of the heel holding member of the example of this invention.
