Since the resilient deforming section 8 is made of the readily deformable material so as to be easily deformed, and accordingly, it has a shape which can be made into close contact with the ground surface line g...g. The body weight of a person can be supported by the tread rear end edge 9 of the heel body section 7.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to shoes that make people look taller, and relates to a technique that allows people (for example, men) who dislike shoes such as high heels that have high heels to make them look taller.

【background】

There are times when people want to look taller, regardless of whether they are men or women.For women, high heels can make you taller, but there is a limit to the height you can increase with women's high heels, and some people dislike the shape of high heels. Therefore, if possible, it would be desirable to have something that can be used by men as well. male m
It is necessary to increase one's height without losing one's masculinity. Some shoes that make you look taller have the following basic structure.For example, as shown in Figure 3, the upper part 2 is fixed to the upper part of the sole part 1, and the upper part 2 is fixed to the upper part of the sole part 1. The heel 3 is fixed to the lower part of the rear part, and the heel ground height H between the rear heel stepping surface 5 of the upper surface 4 of the sole part 1 and the ground contact surface 6 of the heel part 3 is set high. There is.

[Conventional technology]

In the above-mentioned basic structure, conventional structures for making the height appear taller include, for example, Japanese Patent Application Laid-Open No. 82-286401, Jitsuma No. 50-35437, and U.S. Patent Specification No. 437081.
It is stated in issue 7 etc. In addition, if you look into the "shoes that make you look taller" that are currently being sold in Nunouchi, you will find that Niko Co., Ltd., which has the largest and nationwide sales organization, released the shoes in December 1986.
A photograph like the one shown in Figure 2 is published in the O-day issue catalog. According to the catalog, the heel gradually becomes higher toward the rear, and it states that it can increase your height by a maximum of 8 cm. The actual measurement result of this product was a little less than 7 cm when measured directly under the calcaneus. If the photograph of FIG. 2 is drawn in a cross-sectional view and explained, the skeleton 101 of a pair of feet 101 is held in a shoe 103 with a slight fleshy part 102 in between, as shown in FIG. 3. The actual effective height H is the perpendicular line Z passing directly below the calcaneus...
・In figure 1 measured in step 2, the effective height H is 7 cm, the sole thickness is 1 cm, and the heel is 6 cm raised and tilted. (This specification assumes that the shoe size is 26 cm.) Since ordinary men have traditionally worn shoes with heels, assuming that the total heel and sole of commercially available shoes is 4 cm, the products in the catalog ( Even if you purchase and use the product (Fig. 2), you can only increase the height by 3 cm. It is undesirable that the limit is only 3 cm higher than conventional general men's shoes (4 cm in total for heels and soles), but what is even more inconvenient is that this type of "men's shoes that make you look taller""Shoes" are extremely uncomfortable to wear, and the discomfort seems to be proportional to the square of the height. Figure 4 shows the skeleton of a human standing on flat ground, with the knee bone axis X...
...The inclination angle α of the calcaneal end 104 with respect to X-rays is 14 degrees, and the horizontal distance d is 17 mm. If only the heel is raised and the end of the heel bone is raised 6.
When lifted by 0 mm, the knee bone axis i as shown in Figure 5.
ax...Inclination angle β of the heel bone end 104 with respect to X
is 38 degrees, and the horizontal distance is 44 mm. In this case, there is a relationship of sin β D=d, so that the position of the heel bone end 104 is on the knee bone axis X...
・As you move away from X and d becomes more like D, walking becomes more difficult, and walking requires a lot of patience. This product is actually on sale, so you can try it out to see how uncomfortable it is. In this way, we attempted an experiment by using a conventional product sold in cloth, using the same model, and adding only the height. The prototype used in the experiment is as follows. (Prototype) If you modify the product shown in Figures 2 and 3 and add 2 cm 1 l to the height as shown in Figure 6, the inclination of the foot bone will be as shown in Figure 7, and the end of the calcaneus will be 104 cm. is tilted greatly to form an angle γ, and as a result, the distance between the X-ray and the heel bone end 104 becomes as large as 64 mm. If the state in which the calcaneus protrudes rearward in a large distance is depicted in an illustration style, it will look like Figure 9. This is very different from Fig. 8, which shows the case when ordinary shoes are worn, and the heel protrudes significantly backwards. When walking while wearing this prototype, the rear end of the heel 105 collides with the ground upon contact with the ground, causing an intolerable tension on the muscles 108 (FIG. 9). Regarding the effects of distance on knee joints and muscles. For example, it is explained in Japanese Patent Application No. 62-231685. To illustrate this theory, as shown in Fig. 10, at the moment when a person's foot lands on the ground, weight is applied to the heel bone end 104, which generates a force that bends the knee joint 106 in the direction of arrow A. As shown in Figure 11, the knees are bent in a dogleg shape.1
．． The H joint 106 separates from the knee bone axis χ...χ. This phenomenon is repeated step by step, pulling the muscles abnormally and causing lesions in the knee joint. For products of the type shown in Figure 2, the actual maximum length is actually 7 cm, and since walking beyond that becomes painful, commercialization has not been realized. As a means of escaping this pain while walking, there is a
It is necessary to prevent distance #D from becoming larger than d. FIG. 12 shows one example, in which the distance is designed to be close to the distance #d. In other words, the rear end 9 of the ground contact surface of the heel is positioned forward of the rear end of the shoe by the relief dimension E. In this way, the pain that occurs in the case of FIG. 9 will not occur. However, this results in a high heel appearance for women's shoes that is completely different from the men's shoes shown in the catalog. Even if the shoe shape is changed to a boat bottom shape, the rear end 9 of the seed ground will move forward. That is inevitable. There is no need to explain that men dislike wearing such women's shoes.

[Issue to be solved]

■ The rear end of ground contact m9 does not move forward into a feminine shape as shown in Figure 12, and has an appearance that can be used by men as well. ■ The height exceeds the maximum value listed in the catalog (Figure 2). To make it possible for people who want to raise their feet even higher, to make it possible to achieve a height that exceeds the current level.
The purpose is to avoid causing abnormal tension (Figure 9) and joint lesions.

[Means to solve]

A1 Invention 1 Invention 1 is characterized in that, for example, as shown in FIG. 1, a first-order improved structure is combined with the above-mentioned basic structure. Namely. The heel part 3 consists of a heel body part 7 and an elastically deformable part 8. The heel body part 7 is made of a hard material that does not substantially undergo compressive deformation depending on the stepping force during walking. The end edge 9 is positioned forward of the rear surface 10 of the heel portion 3 by the relief dimension E, and the elastic deformation portion 8 is made of a soft elastic material that can be easily elastically deformed by the stepping force during one walk. Position it at least toward the bottom of the rear side. In a ground contact start state A in which the rear end edge 9 of the ground contact surface 6 of the heel main body 7 begins to touch the ground after stepping out, the plane that contacts the ground contact rear end edge 9 is named a ground contact start virtual plane G at the time of stepping. The lower surface 11 of the elastically deformable portion 8 is a virtual plane G at which ground contact starts when stepping.
Move it further down and position it. In the grounding start state A in which the rear end edge 9 of the ground contact surface 6 of the heel main body 7 begins to touch the ground after taking a step, the lower surface 11 of the first elastically deformable portion 8 is moved to the grounding start virtual plane G due to the grounding reaction force F.
The elastically deformable portion 8 is configured to have a shape, size, and structure that allows it to easily elastically deform and escape. B6 Invention 2 Invention 2 is 1, for example, as shown in FIG. This invention is characterized in that the first improved structure is combined with the first invention. That is, in front of the toe storage space 22 in the foot storage space 21 inside the upper 2, a space 23 is formed to prevent the toe C of the foot B from getting caught, and the tip 15 of the upper 2 is The front overhanging space 24 is formed by overhanging forward from the extra space 23. The spaces 23 and 24 are both spaces, and the three spaces may be a series of spaces, or may be filled with stuffing or spacers. C0 Invention 3 Invention 3, for example, as shown in FIG. 1, is characterized in that the following improved structures are combined in the inventions 1 and 2 above. That is, the upper surface 34 of the sole l in the foot accommodation space 21 inside the upper 2 is raised higher than the lower peripheral edge 31 of the upper 2. D0 Invention 4 Invention 4, for example, as shown in FIGS. 16 to 29,
In the inventions 1 to 3 above. It is characterized by a combination of the following improved structures. That is, the heel stepping surface 41 is supported such that its height can be changed. E0 Invention 5 Invention 5 is 1 For example, as shown in FIGS. 32 to 33,
In the inventions 1 to 4 above. It is characterized by a combination of the following improved structures. That is, the ground contact surface of the heel body 7 is formed by three parts, a ground contact surface 51 formed on the inside and a contact surface 52 formed on the outside, spaced apart from each other. A notch 53 is formed in the middle of the three parts, and extends upward away from the ground. F1 Invention 6 Invention 6, for example, as shown in FIGS. 35 to 36,
In the inventions 1 to 5 above. It is characterized by a combination of the following improved structures. That is, in order to make the wear resistance of the outer ground contact surface 52 higher than that of the inner ground contact surface 51, the area of the outer ground contact surface 52 is made larger than the area of the inner ground contact surface 51. Alternatively, the material of the outer ground plane 52 is configured to have higher wear resistance than the material of the inner ground plane 51.

[Effect]

A. Invention 1 Invention 1 operates as follows. That is, FIG. 13 shows a state A in which a person walks and starts touching the ground, and the elastic deformation part 8 is made of a soft elastic material that can be easily elastically deformed, and easily deforms under the weight of the person, as shown in the figure. Ground type...
. . . The zero weight, which is in close contact with gl*, is substantially supported by the trailing edge 9 of the heel body 7 when it touches the ground. In this case, the line 1g...g is the "virtual plane G at the start of ground contact when stepping down" in FIG. It intersects with the ground contact surface S...sli of the shoe at an angle θ2. E is a relief dimension provided for advancing the edge 9. When a person with a leg length of 80 cm walks with a stride length of 60 cm, the ground contact angle θ2 is, for example, 22 degrees. It is preferable that C2 be made sufficiently large in consideration of walking with longer strides or walking on a slope. 0 When the elastic deformation part 8 is made of a sufficiently flexible elastic material, or when a sufficient void is formed. When the knee bends, the harmful "knee bending action" described above with reference to FIGS. 11 and 9 does not occur, and the pulling of the muscle 108 does not cause lesions in the knee joint. As explained above, if there is a deformable part in the distance #E behind the rear heel 9, the knee bending phenomenon will not occur when the rear heel 9 touches the ground, but when this shoe is actually used. This seems to be an effect that cannot be fully explained by the above explanation alone. The reason for this is probably the problems caused by traditional thick-heeled shoes.
This is thought to be because the shoe does not fall forward when it touches the ground. Figure 14 shows the phenomenon of falling forward when it touches the ground, and is the moment when a thick-heeled shoe touches the ground. When it touches the ground, a force is generated that causes the shoe to fall in the direction of the arrow. The downward arrow in the diagram indicates the influence of gravity, and the forward arrow indicates forward movement due to inertia.As a result, gravity and inertia act synergistically, causing the ankle to fall forward.This "forward falling phenomenon" This occurs particularly when the human body is heavy and walks at a high speed.This causes the muscles 108 to become painful as shown in FIG. 9, making walking painful.According to the present invention, the elasticity The deformed portion 8 deforms flexibly, and as a result, the fulcrum for supporting one's body weight moves to the rear edge 9 of heel contact, and as a result, arrow A in Figure 11, forward arrow, downward arrow in Figure 14, Disorders based on the "forward falling phenomenon" such as muscle tension in the case of Figure 9 can be prevented. B6 Invention 2 Invention 2 works as follows. That is, the catalog product (Figure 2) When in use, the skeletal condition is as shown in Figure 5, where the foot is slanted and the horizontal distance Y from front to back is short.If the shoes are fitted to such a short dimension Y, the shoes will have a feminine short dimension. Unfortunately, short people often have small ankles (sole of the foot), and when the sole of the foot slopes like a high heel, the shoes become shorter and the horizontal distance Y becomes smaller. Disadvantages 0 In the present invention, the heel part is made high to make the person look taller, so even if the horizontal distance Y between the soles of the foot is shortened, as shown in Fig. By forming the tip 15 of the instep 2 in front of the front overhanging space 24, even if the sole of the foot is inclined and the horizontal distance Y is shortened as shown in Fig. 7, it can be used by a man with a large size that is manly. It is generally said that when a person wears shoes that are disproportionately large, muscles become strained.However, the effect of Invention 1 prevents muscle tension, so the synergistic effect of Invention 1 and Invention 2 , Even if you wear shoes that are larger than your feet, as in invention 2, the phenomenon of muscle tension does not occur. It is narrow, and becomes thicker and wider as it moves away from the front end.In the above-mentioned invention 2, as shown in Figure 1, the upper
An extra overhanging space 24 is provided at the front end of the toe section C, so that the ceiling 32 of the toe section C is sufficiently high.The present invention 3 utilizes the lower space of this raised ceiling 32. For normal shoe soles, a slight insole may be used when the lower peripheral edge 31 of the upper 2 is in contact with the sole 1, but even in that case, there is a limit to the thickness of the insole, and the toe All I had to do was use something thin enough not to hit the upper part 2. However, in the above-mentioned invention 2, since the ceiling 32 of the toe part is high, the upper surface of the sole at the toe part 34 is made higher than the upper surface 4 of the sole part. The height can be increased by h. As a result of lifting it up high in this way, the height that can be lifted can be further increased compared to when only the heel part is lifted, as in the product described in the catalog (Fig. 2). D0 Invention 4 Invention 4 operates as follows. Namely. The aforementioned inventions 1 to 3. Although inventions 5 and 6 described later enable short men to appear taller, there is only one drawback. That is, when you take off your shoes, other people can see them. The present invention 4 alleviates this drawback, which is that the bottom is shallow. In FIG. 16, the stepping surface 41 is supported by a support shaft 42, and the support shaft 42 is slidably held in a hole 43 provided in the heel body 7. The support shaft 42 has a notch 44, the heel body 7 has a locking piece 45, and the locking piece 45 is biased toward the notch 44 (
(explained in the Examples section). When a person removes the locking piece 45 with his/her finger against the urging force, the heel stepping surface 41 falls down and becomes a low stepping surface 46 as shown in FIG. 18 with one touch. E1 Invention 5 Invention 5 operates as follows. That is, the heel stepping surface 5 is raised to a height 1 that has never been experienced before.
For example, if it becomes 120mm. Unexpected obstacles appear. When you actually walk on the road with such 120 mm shoes, you will notice that they tend to fall sideways. Figure 30 shows an example of this, where the heel part W is 80 mm and the height H of the heel stepping surface is 120 mm. Then, the height H is 1.5 times as large as the width W. As shown in FIG. 31, when the road is uneven, the vehicle becomes unstable in the lateral direction and "falls sideways". FIG. 32 is a side view depicting only the heel body 7 in the form of a partial part when the present invention 5 is implemented. Seed nucleus ground 6 is the 33rd
As shown in the figure (rear view), there is a ground plane 51 formed on the inside and a ground plane 52 formed on the outside.
The three parties were formed at a distance from each other. A notch 53 is formed between the ground plane 51 and the ground plane 52, and is spaced apart from the ground and recessed upward, so as not to contact the ground. Therefore, even if the road is uneven, as shown in FIG. 34, for example, it is less likely that the vehicle will fall sideways due to the unevenness of the road. F0 Invention 6 Invention 6 operates as follows. In other words, when a man walks, the lower end of the calcaneus is "slightly on the outside" at the moment when the heel contacts the ground surface, and the weight is supported from the outside (left and right outside of humans) toward the center of the body. Ru. Therefore, the heels of men's shoes generally wear out first from the outside of the shoe,
The heel gradually "declines." However, in the case of a high heel as shown in FIGS. 32 and 33, when the outer side begins to decrease, extra weight is placed on the lower heel, accelerating wear on the outer side. Shoes that reduce the outside of the heel in this way are bad for the knee joints, causing the knees to develop genu varum (genu varus, cranial crotch), and leading to various knee joint disorders. In order to prevent the occurrence of such lesions and to stably maintain the high tread surface 5, in the present invention 6, the inner tread surface 51
The wear resistance of the outer ground contact surface 52 is made higher than that of the outer contact surface 52. For this purpose, (a) the area of the outer ground plane 52 is formed larger than the area of the inner ground plane 51; or. (b) The material of the outer ground contact surface 52 is configured to have higher wear resistance than the material of the inner ground contact surface 51. In this case, both (a) and (b) above may be used together. FIG. 35 is a rear view with a portion of the heel body 7 temporarily taken out, showing an example in which the area of the inner ground contact surface 51 and the outer contact surface 52 is different, and FIG. 36 and FIG. 37 are bottom views of the same. . By creating a difference in ground contact area and abrasion resistance between the inner and outer sides, even if the bottom of the shoe wears out after long-term use, this prevents the outer side from wearing out first, and the inner and outer sides wear out. Wear progresses gradually while maintaining balance, and "leaning" is prevented.

【Effect of the invention】

A1 Invention 1 Since the present invention 1 is configured and operates as described above, it has the following effects. ■ Since the elastically deformable portion 8 deforms flexibly, even if the actual fulcrum that supports the body weight (the rear end of the heel bottom 9) is located forward by the dimension E, the elastically deformable portion 8 is - It can be advanced below the G line, so the appearance of the heel part does not look strange and can be made to look like a normal male heel. ■ When you take a step and the rear edge of the contact surface of the heel body begins to touch the ground, the "forward fall phenomenon" in which the ankle or knee falls forward does not occur. ■ As a result, there is no undue tension in the muscles, so you can walk without pain and no lesions occur in the knee joints. ■ Therefore, for example, 12
It can be as high as 0 mm. B1 Invention 2 Since the present invention 2 is configured and operates as described above, it has the following effects. ■ Even if the ankle is inclined like a high heel with a high heel stepping surface such as 120 mm as described in (2) above, the horizontal dimensions of the shoe will not become short, and in the case of shoes for men, the manly dimensions can be maintained. ■ As a result, you end up wearing shoes that are unsuitable for you, but due to the synergistic effect of effect ■ and effect ■, even if you wear shoes that are unsuitable for you, you will not experience muscle tension. C8 Invention 3 Since the present invention 3 is configured and operates as described above, it has the first effect. ■ Compared to the method of raising only the heel, a significantly higher heel stepping surface 5 can be obtained, and due to the synergistic effect with the above-mentioned effects ■ ~ Effect ■, there is no muscle tension, so it is possible to easily reach heights such as 120 mm. A high heel stepping surface height can be achieved. Invention 4 Invention 4 is configured and operates as described above, and therefore has the first effect. (2) If you do not want others to see your high heel stepping surface, such as when you take off your shoes, you can lower the heel stepping surface with a one-touch operation as in the fourth embodiment. E1 Invention 5 Since the present invention 5 is configured and operates as described above, it has the first effect. ■ Since it is possible to reduce the "sideways fall" caused by falling from side to side due to unevenness of the road, the synergistic effect with effect (■) to effect (2) allows the user to walk safely on uneven roads even if the heel depression surface is as high as 120 mm. F0 Invention 6 Since the present invention 6 is configured and operates as described above, it has the following effects. [Phase] Wear progresses evenly on the inside and outside of the heel, so
120m that does not “decrease inclination” even when the heel sole wears out
Safety is required in the case of high heel-pressing hematopoiesis such as m, but the present invention is safe without ``reducing the slope''. This means that the height can be made taller, and it can be made taller than currently possible with commercially available products.For convenience of explanation, the height is assumed to be, for example, 120 mm, but if there is a case where a higher one is desired, for example, 1
A length of 50 mm or more is also possible. (Example)

[Embodiment 1] [Invention 1] [See FIG. 1] In FIG. 1, a shoe 12 is constructed of leather, rubber, synthetic resin, etc., singly or in combination. In order to make the shoes lighter, it is preferable to use a large amount of foamed resin that contains a large amount of gas to reduce weight. Furthermore, a large number of void spaces 13 are formed to reduce the weight. A lower peripheral edge 31 of the upper 2 is fixed to the upper surface 4 of the sole 1. The heel part 3 consists of a heel body part 7 and an elastically deformable part 8, and the heel stepping surface 5 at the rear of the sole 1 is connected to the heel part 3.
In this example, the ground height H between the ground plane 6 and the ground plane 6 is 12.0 m.
It is set to m. The heel main body part 7 is made of a hard material that does not substantially undergo compressive deformation depending on the stepping force during one walk, and the rear edge 9 of the contact surface 6 of the heel main body 7 is made to escape to the front side of the rear surface 10 of the heel part 3. It is positioned by moving it forward by a dimension E (40 mm in this example). The heel body 7 is embedded in the sheath body 12 and cannot be attached or detached, but if it is taken out and shown in the form of parts, Figure 32 (side view) and Figure 33 (rear view) )
The lower surface 54 is made of a wear-resistant material such as urethane resin, and the outer surface 52 has a larger area than the inner surface 51 as shown in FIGS. 35, 36, and 37. It is. Instead of providing a difference in area between the inner side 51 and the outer side 52, a difference may be provided in the wear resistance of the wear-resistant materials, and the outer side 52 may be provided with greater wear resistance than the inner side 51. The elastically deformable portion 8 is made of a soft elastic material that can be easily elastically deformed by stepping force during walking, and has a cavity 14 formed therein so as to be easily elastically deformed. Furthermore, the lower surface 11 of the elastically deformable portion 8 is formed with an angle θ deviating upward so that the elastically deformable portion 8 is easily deformed. This angle θ1 is set to a level that is not noticeable or unsightly, such as 1 degree, for example, 10 degrees. The elastic deformation portion 8 is located at the rear of the heel body portion 7, and is located at least (at least at a lower position) at a lower portion of the heel body portion 7. It may also be formed to extend upwardly. When forming the void 14, the elastically deformable portion 8 becomes thin and easily wears out and breaks, so in that case, a material that has both elastic deformability and abrasion resistance, such as urethane resin, is used. Preferably, this elastically deformable portion 8 may have a bottom 16, or may be bottomless and skirt-shaped. In a grounding start state A in which the rear edge 9 of the ground contact surface 6 of the heel body 7 begins to touch the ground after stepping out, a plane in contact with the rear edge 9 of the heel body 7 is referred to as a "virtual ground contact start plane G upon stepping".
1. The lower surface 11 of the elastic deformation part 8 is extended below the virtual plane G at which ground contact starts when stepping on the ground.
・It is formed close to the g-line (or the contact surface S...sm of the shoe). On the lower surface 11 of the elastic deformation part 8, there is a ground contact force F that initiates ground contact when stepping down in the above-mentioned ground contact start state A. The elastically deformable portion 8 is configured to have a shape, size, and structure that easily elastically deforms and escapes to the virtual plane G.

There is a space 2 on the front side of 2 that prevents the toe C of foot B from getting stuck.
3, and make the tip 15 of the upper 2 protrude from the cut-off space 23 to the forward overhanging space 24/ by an extra amount. Even if you end up wearing shoes, muscle tension will not occur due to the synergistic effect of effect ① and effect ②.Space 23 and space 24 are considered as a series (integral) space, as disclosed in Japanese Patent Application No. 63-214366. It may also be formed as
It may be filled with stuffing or spacers. [Embodiment 3] [Invention 3] [See FIG. 1] Upper surface 34 of the sole 1 in the foot accommodation space 21 inside the upper 2
It is formed so that it is raised and positioned one step higher than the lower peripheral edge 31 of the upper part 2. In this embodiment, the height h above the ground of the upper surface 34 is set to 60 mm. As a means of maintaining this height of 60 mm, a removable insole-like mat 18 may be used.Even in such an insole-like configuration, only the portion 19 that receives the load of the calcaneus is substantially It is better to use a material that does not undergo compressive deformation even under load. The above description has been made assuming that the height of the heel stepping surface 5 above the ground is 120 mm, but if a short person desires a higher height, the heel stepping surface 5 can be designed higher, for example, 150 mm or more. In Figure 38, the height of the heel stepping surface is 150 mm.
Here is an example of a design.

[Example 4] [Invention 4] [See Figures 16 to 29]

As shown in Fig. 8, a low stepping surface 46 can be achieved with one touch.

【mouth】

This embodiment (b) is also an embodiment of the fourth invention. In FIG. 19, a support shaft 40 supporting the heel stepping surface 41
1 is formed with a convoluted protrusion 402. The lower part of the support shaft 401 is slidably held in the hole 403, and the heel body 7 is formed with a concession-shaped hole 403 as shown in FIG. 20, and a concession-shaped projection 402 is formed as shown in FIG. 19. The height of the stepping surface 41 is maintained by contacting the upper surface of the heel body 7.
