  • the present invention relates to a floor structure of a high-heeled shoe having a walking mechanism similar to a movement of a human walking when a pedestrian wears high-heeled shoes and walks, and a high-heeled shoe having the same.
  • Pedestrians wearing conventional high-heeled shoes experience ankle sprain due to poor stability of the rearfoot due to high heels when the weight of the human body is loaded on the ground during standing or walking. Therefore, the sole structure of a conventional high-heeled shoe is made of a very hard material in which a metal shank is inserted from the rear boundary of the front portion, which is the portion where the shoe is in contact with the ground to the ground, to the end of the rear foot.
  • the foot of the conventional high-heeled shoes is in a state in which the plantar fascia is pulled tight, a passive movement of bending the toes toward the floor occurs. Therefore, the foot in a state in which high-heeled shoes are worn has a force to bend toward the ground in the front portion, which is a part supported by the ground of high-heeled shoes. Therefore, the front part of the high-heeled shoe is made firmly to maintain the shape of the shoe in a swing phase where the human body's weight is not loaded on the ground. In particular, when the platform is attached to the bottom of the front portion supported on the ground of high-heeled shoes, movement of the forefoot and rearfoot is not allowed at all.
  • extension occurs in the direction of the instep in the metatarsophalangeal joints during the heel off and toe off periods after midstance.
  • the floor structure of the conventional high heel is not flexible, there is a problem in that the heel comes out of the shoe and normal walking is difficult.
  • Figure 24 is a side cross-sectional view showing the main structure of the foot skeleton and shoes in a state in which the conventional high-heeled shoes are worn
  • Figure 25 is a wooden shape (last, also referred to as'last') used to manufacture the conventional high-heeled shoes. It is a diagram showing a general floor structure.

  • high-heeled shoes are made by combining the heel (H) and the outsole (O) with the general floor structure (S).
  • the general floor structure (S) is from the rear boundary BL of the part supporting the ground (part A in FIG. 24) to the end of the forefoot (dot in FIG. 25) for standing or walking stability.
  • a metal shank (MS) is inserted in part B). That is, the general floor structure (S) is a very rigid metal shank (MS, metal shank) connected from the rear boundary (BL) portion of the portion supporting the ground to the rear foot.
  • the part of the foot where the weight is loaded is the heel, the 1st heads of metatarsal bones, and the 5th heads of metatarsal bones.
  • the three points described above are connected to each other in an arc shape, thereby enabling efficient weight loading and walking.
  • the heads of metatarsal bones are artificially raised on their backs. Therefore, in the conventional floor structure S, the part B floating in the air without being supported by the ground is made of a very sturdy material.
  • the heel (H) of the high-heeled shoe is coupled to the rear of the conventional floor structure (S) to maintain the shape of the shoe.
  • 26 is a view for explaining the state of the extension of the metatarsophalangeal joints in a state in which conventional high-heeled shoes are worn.
  • the metatarsophalangeal joint In general, when wearing high-heeled shoes, the metatarsophalangeal joint (MTP) always maintains a stretched state due to the shape of the shoe, and the plantar fascia (PF) is pulled taut (Fig. Indicated by arrows). When the plantar fascia (PF) is pulled in this way, a passive movement (flexion) that flexes the metatarsophalangeal joint (MTP) occurs, causing the toes to bend toward the soles of the feet (in FIG. 26). Indicated by solid arrows). Therefore, the part that supports the ground in high-heeled shoes is manufactured to some extent to maintain the shape of the shoes.

  • the floor structure S is not bent during a heel off period even if the portion supporting the ground is made to some extent.
  • weight is loaded to the ground through the metatarsal head (MTBH), so even if the heel falls off the ground, the front of the foot, including the metatarsal head (MTBH), remains attached to the ground. Therefore, in the conventional floor structure S, even if the portion supporting the ground is somewhat flexible, the floor structure S is not bent during a heel off period, so that the heel comes out of the shoe.
  • the metatarsal head falls off the ground, and only the toe is loaded with weight. Therefore, when the part supporting the ground in the conventional floor structure S is made to some extent, it may be bent to some extent in the lower part of the metatarsophalangeal joint. However, even in this case, it is not bent enough to follow the foot movement, and as shown in FIG. 27(c), the heel comes out of the shoe further.

Description

굽 높은 신발의 바닥구조물 및 이를 구비한 굽 높은 신발High-heeled shoes with floor structure and high-heeled shoes
본 발명은 보행자가 굽 높은 신발을 착용하고 보행할 때 인간 보행의 움직임과 유사한 보행 메커니즘을 가지는 굽 높은 신발의 바닥구조물 및 이를 구비한 굽 높은 신발에 관한 것이다.The present invention relates to a floor structure of a high-heeled shoe having a walking mechanism similar to a movement of a human walking when a pedestrian wears high-heeled shoes and walks, and a high-heeled shoe having the same.
인간의 보행주기 중 입각중기(midstance) 이후 발뒤꿈치떼기(heel off)와 발가락떼기(toe off) 시기에 중족지관절(metatarsophalangeal joints)에서 발등 방향으로 굴곡(신전, extension)이 발생하고 동시에 발뒤꿈치(heel of foot)의 내번(inversion)과 내전(adduction)의 움직임이 발생한다.During the human walking cycle, after midstance, heel off and toe off, metatarsophalangeal joints in the direction of instep in the direction of the instep (extension), and simultaneously heel Movement of inversion and adduction of (heel of foot) occurs.
종래의 굽 높은 신발을 신은 보행자는 기립(standing)이나 보행 중 인체의 체중이 지면에 부하될 때 뒷굽이 높아 후족부(rearfoot)의 안정성이 떨어져 발목 접질림(ankle sprain)을 겪는다. 따라서 종래의 굽 높은 신발의 바닥구조물(sole structure)은 신발이 지면과 닿아 지면에 지지되는 부분인 전면부분의 후방 경계에서부터 후족부 끝까지 금속 생크(metal shank)가 삽입된 매우 단단한 재질이 사용된다.Pedestrians wearing conventional high-heeled shoes experience ankle sprain due to poor stability of the rearfoot due to high heels when the weight of the human body is loaded on the ground during standing or walking. Therefore, the sole structure of a conventional high-heeled shoe is made of a very hard material in which a metal shank is inserted from the rear boundary of the front portion, which is the portion where the shoe is in contact with the ground to the ground, to the end of the rear foot.
또한, 종래의 굽 높은 신발을 신은 상태의 발은 족저근막(plantar fascia)이 팽팽하게 당겨진 상태이므로 발가락들을 바닥 쪽으로 굴곡시키는 수동적 움직임(passive movement)이 발생한다. 따라서 종래의 굽 높은 신발을 신은 상태의 발은 굽 높은 신발의 지면에 지지되는 부분인 전면부분도 지면방향으로 구부러지려는 힘이 작용한다. 따라서 굽 높은 신발의 전면부분은 인체의 체중이 지면에 부하되지 않는 유각기(swing phase)에 신발의 형상을 유지하기 위해 견고하게 제작된다. 특히, 굽 높은 신발의 지면에 지지되는 전면부분의 바닥에 플랫폼(platform)이 부착되는 경우에는 전족부(forefoot)와 후족부(rearfoot)의 움직임이 전혀 허용되지 않는다. In addition, since the foot of the conventional high-heeled shoes is in a state in which the plantar fascia is pulled tight, a passive movement of bending the toes toward the floor occurs. Therefore, the foot in a state in which high-heeled shoes are worn has a force to bend toward the ground in the front portion, which is a part supported by the ground of high-heeled shoes. Therefore, the front part of the high-heeled shoe is made firmly to maintain the shape of the shoe in a swing phase where the human body's weight is not loaded on the ground. In particular, when the platform is attached to the bottom of the front portion supported on the ground of high-heeled shoes, movement of the forefoot and rearfoot is not allowed at all.
또한, 입각중기(midstance) 이후의 발뒤꿈치떼기(heel off)과 발가락떼기(toe off) 시기에 중족지관절(metatarsophalangeal joints)에서 발등 방향으로 신전(extension)이 발생한다. 그러나 종래의 하이힐의 바닥구조물은 유연하지 않으므로 이에 대응하지 못하여 발뒤꿈치가 신발에서 빠져 나와 정상적인 보행이 어려워지는 문제점이 있다. In addition, extension occurs in the direction of the instep in the metatarsophalangeal joints during the heel off and toe off periods after midstance. However, since the floor structure of the conventional high heel is not flexible, there is a problem in that the heel comes out of the shoe and normal walking is difficult.
도 24는 종래의 굽 높은 신발을 신은 상태에서 발골격과 신발의 주요구조물을 도시한 측단면도이고, 도 25는 종래의 굽 높은 신발을 제작하는데 사용되는 목형(last, '라스트'라고도 함)과 일반적인 바닥구조물을 도시한 도면이다. Figure 24 is a side cross-sectional view showing the main structure of the foot skeleton and shoes in a state in which the conventional high-heeled shoes are worn, and Figure 25 is a wooden shape (last, also referred to as'last') used to manufacture the conventional high-heeled shoes. It is a diagram showing a general floor structure.
일반적인 굽 높은 신발은 다음과 같은 과정을 통해 제작된다.In general, high-heeled shoes are produced through the following process.
먼저, 굽 높은 신발은 일반적인 바닥구조물(S, sole structure)과 목형(L, last)이 결합된 상태에서 갑피(U)를 씌운 후에 일반적인 바닥구조물(S)에 갑피(U)를 단단히 결합시키는 과정을 통해 제작된다. 그리고 굽 높은 신발은 일반적인 바닥구조물(S)에 뒷굽(H)과 아웃솔(O)을 결합하여 제작된다. 일반적인 바닥구조물(S)은 기립(standing)이나 보행의 안정성(stability)을 위해 지면을 지지하는 부분(도 24의 A 부분)의 후방 경계(BL)에서부터 후족부 끝까지(도 25에서 도트(dot)로 표시된 B 부분)에 금속 생크(MS, metal shank)가 삽입되어 있다. 즉, 일반적인 바닥구조물(S)은 지면을 지지하는 부분의 후방 경계(BL) 부분에서 후족부까지 연결되는 매우 단단한 금속 생크(MS, metal shank)가 결합된다.First, the high-heeled shoes are covered with the upper (U) in a state in which the general floor structure (S, sole structure) and the wooden shape (L, last) are combined, and then the process of firmly bonding the upper (U) to the general floor structure (S) Is produced through. And high-heeled shoes are made by combining the heel (H) and the outsole (O) with the general floor structure (S). The general floor structure (S) is from the rear boundary BL of the part supporting the ground (part A in FIG. 24) to the end of the forefoot (dot in FIG. 25) for standing or walking stability. A metal shank (MS) is inserted in part B). That is, the general floor structure (S) is a very rigid metal shank (MS, metal shank) connected from the rear boundary (BL) portion of the portion supporting the ground to the rear foot.
한편, 발에서 체중이 부하되는 부위는 발뒤꿈치, 첫번째 중족골두(1st heads of metatarsal bones), 그리고 다섯번째 중족골두(5th heads of metatarsal bones)이다. 상술한 세 지점은 서로 아치형태로 연결되어 있어 효율적인 체중부하와 보행을 가능하게 한다. On the other hand, the part of the foot where the weight is loaded is the heel, the 1st heads of metatarsal bones, and the 5th heads of metatarsal bones. The three points described above are connected to each other in an arc shape, thereby enabling efficient weight loading and walking.
굽 높은 신발에서 중족골두(MTBH, heads of metatarsal bones)는 그의 후방부가 인위적으로 올라가 있다. 따라서 종래의 바닥구조물(S) 중 지면에 지지되지 않고 공중에 떠 있는 부분(B)은 매우 견고한 재질이 사용된다. 또한, 굽높은 신발의 뒷굽(H)은 종래의 바닥구조물(S)의 후방에 결합되어 신발의 형상을 유지한다. In high-heeled shoes, the heads of metatarsal bones (MTBH) are artificially raised on their backs. Therefore, in the conventional floor structure S, the part B floating in the air without being supported by the ground is made of a very sturdy material. In addition, the heel (H) of the high-heeled shoe is coupled to the rear of the conventional floor structure (S) to maintain the shape of the shoe.
도 26은 종래의 굽 높은 신발을 신은 상태에서 중족지관절의 신전(extension of metatarsophalangeal joints) 상태를 설명하기 위한 도면이다.26 is a view for explaining the state of the extension of the metatarsophalangeal joints in a state in which conventional high-heeled shoes are worn.
일반적으로 굽 높은 신발을 신게 되면, 중족지관절(MTP)은 신발의 형상으로 인해 항상 신전된 상태를 유지하게 되어, 족저근막(PF, plantar fascia)이 팽팽하게 당겨지게 된다(도 26에서 가상선의 화살표로 표시함). 이와 같이 족저근막(PF)이 당겨지면, 중족지관절(MTP, metatarsophalangeal joint)을 굴곡(flexion)시키는 수동적 움직임(passive movement)이 발생하여 발가락들이 발바닥 쪽으로 구부러지려는 힘이 발생한다(도 26에서 실선의 화살표로 표시함). 따라서 굽 높은 신발에서 지면을 지지하는 부분은 신발의 형상을 유지하기 위해 어느 정도 견고하게 제작된다.In general, when wearing high-heeled shoes, the metatarsophalangeal joint (MTP) always maintains a stretched state due to the shape of the shoe, and the plantar fascia (PF) is pulled taut (Fig. Indicated by arrows). When the plantar fascia (PF) is pulled in this way, a passive movement (flexion) that flexes the metatarsophalangeal joint (MTP) occurs, causing the toes to bend toward the soles of the feet (in FIG. 26). Indicated by solid arrows). Therefore, the part that supports the ground in high-heeled shoes is manufactured to some extent to maintain the shape of the shoes.
도 27의 (a) 내지 (c)는 종래의 굽 높은 신발의 문제점을 설명하기 위한 도면이다. 도 27의 (a)는 굽 높은 신발을 신은 상태에서 기립(standing)이나 보행 중 입각중기(midstance)를 도시한 도면이고, 도 27의 (b)는 보행 중 발뒤꿈치떼기(heel off) 시기를 도시한 도면이며, 도 27의 (c)는 보행 중 발가락떼기(toe off) 시기를 도시한 도면이다. 27(a) to 27(c) are diagrams for explaining the problem of the conventional high-heeled shoes. FIG. 27(a) is a view showing standing or midstance while walking while wearing high-heeled shoes, and FIG. 27(b) shows a time when heel off during walking. FIG. 27(c) is a view showing a toe off period during walking.
종래의 바닥구조물(S)은 지면을 지지하는 부분이 어느 정도 유연하게 제작되더라도 발뒤꿈치떼기(heel off) 시기에는 바닥구조물(S)이 구부러지지 않는다. 발뒤꿈치떼기(heel off) 시기에는 중족골두(MTBH)를 통해 체중이 지면으로 부하되므로 발뒤꿈치가 지면으로부터 떨어지더라도 중족골두(MTBH)를 포함한 발의 전면부는 지면과 붙어있게 된다. 따라서 종래의 바닥구조물(S)은 지면을 지지하는 부분이 어느 정도 유연하더라도 발뒤꿈치떼기(heel off) 시기에는 바닥구조물(S)이 구부러지지 않게 되어, 발뒤꿈치가 신발에서 빠져 나오게 된다. In the conventional floor structure S, the floor structure S is not bent during a heel off period even if the portion supporting the ground is made to some extent. During the heel off period, weight is loaded to the ground through the metatarsal head (MTBH), so even if the heel falls off the ground, the front of the foot, including the metatarsal head (MTBH), remains attached to the ground. Therefore, in the conventional floor structure S, even if the portion supporting the ground is somewhat flexible, the floor structure S is not bent during a heel off period, so that the heel comes out of the shoe.
발가락떼기(toe off) 시기에는 중족골두(MTBH)가 지면으로부터 떨어지면서 발가락으로만 체중이 부하된다. 따라서 종래의 바닥구조물(S)에서 지면을 지지하는 부분이 어느 정도 유연하게 제작될 경우, 중족지관절(metatarsophalangeal joint)의 하방 부위에서 어느 정도 구부러질 수 있다. 하지만, 이 경우에도 발 움직임을 따라갈 정도로 충분히 구부러지지 않게 되어, 도 27의 (c)에 도시한 바와 같이 발뒤꿈치는 신발에서 더욱 빠져 나오게 된다.During the toe off period, the metatarsal head (MTBH) falls off the ground, and only the toe is loaded with weight. Therefore, when the part supporting the ground in the conventional floor structure S is made to some extent, it may be bent to some extent in the lower part of the metatarsophalangeal joint. However, even in this case, it is not bent enough to follow the foot movement, and as shown in FIG. 27(c), the heel comes out of the shoe further.
따라서 종래의 바닥구조물(S)이 적용된 굽 높은 신발은 보행에 따른 발의 움직임을 따라가지 못하고 발을 지지(support)하지 못하게 된다.Therefore, the high-heeled shoes to which the conventional floor structure S is applied cannot follow the movement of the foot due to walking and cannot support the foot.
따라서, 본 발명은 상기한 문제점을 해결하기 위하여 제안된 것으로써, 본 발명의 목적은 유각기(swing phase)에는 중족지관절(metatarsophalangeal joint)의 굴곡(flexion)을 제한하여 신발의 형상을 유지하고, 지면에 체중이 부하되는 입각기(stance phase)나 기립(standing) 시에는 체중을 지지하여 보행의 안정성을 향상시키는 굽 높은 신발의 바닥구조물 및 이를 구비한 굽 높은 신발을 제공하는데 있다. Therefore, the present invention is proposed to solve the above problems, and the object of the present invention is to limit the flexion of the metatarsophalangeal joint in the swing phase to maintain the shape of the shoe, In order to improve the stability of walking by supporting the weight in the case of standing or standing in a standing phase where weight is loaded on the ground, it is to provide a high-heeled shoe with a bottom structure of the high-heeled shoe.
본 발명의 다른 목적은 보행 중 발뒤꿈치떼기(heel off) 및 발가락떼기(toe-off) 시기에 중족지관절(metatarsophalangeal joint)의 신전(extension)이 가능하도록 하여 발의 움직임에 최적화되는 굽 높은 신발의 바닥구조물 및 이를 구비한 굽 높은 신발을 제공하는데 있다.Another object of the present invention is to allow the extension of the metatarsophalangeal joint during heel off and toe-off during walking, and the high-heeled shoes optimized for the movement of the foot. It is to provide a floor structure and high-heeled shoes with the same.
상기와 같은 본 발명의 목적을 달성하기 위하여, 본 발명은 지면을 지지하는 프론트부, 상기 프론트부에서 연장되어 중족지관절의 후방부에 위치하고 지면 반대 방향으로 구부러지는 밴딩부, 그리고 상기 밴딩부에서 연장되는 리어부를 포함하는 굽 높은 신발의 바닥구조물을 제공한다.In order to achieve the object of the present invention as described above, the present invention is a front portion that supports the ground, a bending portion that extends from the front portion and is positioned at a rear portion of the metatarsal joint and bends in the opposite direction to the ground, and the bending portion It provides a floor structure of a high-heeled shoe including an extended rear portion.
상기 밴딩부는 지면 반대방향으로 오목한 곡면을 이루는 밴딩곡면부로 이루어지는 것이 바람직하다.The bending portion is preferably made of a bending curved portion forming a concave curved surface in the opposite direction to the ground.

맨발을 기준으로 인간의 보행 주기에 따른 발의 움직임을 도 6을 통해 설명한다.The movement of the foot according to the human walking cycle based on the bare foot will be described with reference to FIG. 6.
도 6의 (a) 내지 (e)는 인간의 보행 주기를 설명하기 위한 도면이다.6A to 6E are diagrams for explaining a human walking cycle.
인간의 보행 주기는 한쪽 발(도면에서 빗금으로 표시한 부분)을 기준으로 입각기(stance phase)와 유각기(swing phase)로 구분된다.The walking cycle of a human is divided into a stance phase and a swing phase based on one foot (the portion indicated by hatching in the drawing).
입각기(stance phase)는 보행 중 발의 일부분이 지면에 닿아 있는 상태이다. 이러한 입각기(stance phase)는 발뒤꿈치접지(heel strike), 하중반응기(loading response), 입각중기(midstance), 발뒤꿈치떼기(heel off), 및 발가락떼기(toe off)의 5단계로 구분할 수 있다. In the stance phase, a part of the foot is in contact with the ground while walking. This stance phase can be divided into five stages: heel strike, loading response, midstance, heel off, and toe off. have.
발뒤꿈치접지(heel strike)는 발뒤꿈치가 지면에 접촉되는 순간을 의미한다. 하중반응기(loading response)는 발뒤꿈치접지(heel strike) 후에 발바닥 전체가 지면에 접촉되는 단계이다.Heel strike means the moment when the heel comes into contact with the ground. The loading response is a step in which the entire sole comes into contact with the ground after a heel strike.
발뒤꿈치접지(heel strike)와 하중반응기(loading response)는 지면으로부터의 충격을 흡수하고 체중을 분산시키는 과정이다(도 6의 (a)와 (b)에 도시함). 입각중기(midstance)는 다리가 지면에 수직으로 놓여 있는 상태로 발에 체중이 최대로 실리는 단계이다(도 6의 (c)에 도시함). 발뒤꿈치떼기(heel off)는 발의 뒤꿈치가 지면에서 떨어지는 단계이다(도 6의 (d)에 도시함). 발가락떼기(toe off)는 발 끝이 지면에서 떨어지는(the toes leave the ground) 단계이다(도 6의 (e)에 도시함). Heel strike and loading response is a process of absorbing impact from the ground and dispersing body weight (shown in FIGS. 6(a) and 6(b)). Midstance (midstance) is a stage in which the weight is placed on the feet to the maximum with the legs perpendicular to the ground (shown in Fig. 6(c)). Heel off is the stage where the heel of the foot falls off the ground (shown in Figure 6(d)). Toe off is the step of the toes leave the ground (shown in Figure 6(e)).
한편, 유각기(swing phase)는 발 전체가 지면과 떨어져 있는 상태를 의미한다. 유각기 동안에는 발가락 들림(toe clearance)이 충분하여야 한다. 즉, 발끝이 지면에 끌리거나(toe drag) 걸리지 않아야 낙상의 위험성이 줄어들어 안정적인 보행이 이루어진다. 보행은 입각기와 유각기(swing phase)가 반복적으로 순환하면서 이루어진다.On the other hand, the swing phase (swing phase) refers to the state of the entire foot away from the ground. There should be sufficient toe clearance during the swing phase. That is, when the toe is not dragged to the ground (toe drag), the risk of falling is reduced and stable walking is achieved. Gait is achieved by repetitive cycles of the standing phase and swing phase.
도 7의 (a)는 맨발 보행 중 발뒤꿈치떼기(heel off) 상태의 측면이고, 도 7의 (b)는 맨발 보행 중 발뒤꿈치떼기(heel off) 상태를 후방(발뒤꿈치 측)에서 본 도면이다.Figure 7 (a) is a side view of the heel off (heel off) state while walking barefoot, and Figure 7 (b) is a view of the heel off (heel off) state while walking barefoot from the rear (heel side) to be.
입각중기(midstance) 이후에는 발뒤꿈치가 지면에서 떨어지므로, 지면과 접촉하는 전면부 발(front foot)을 기준으로 발뒤꿈치의 움직임이 발생한다. 발뒤꿈치떼기(heel off) 단계에서는 중족골두(MTBH)부터 발가락 끝까지 지면과 접촉하여 체중이 지면으로 부하된다.After the midstance, since the heel falls off the ground, the movement of the heel occurs based on the front foot contacting the ground. In the heel off stage, the weight comes into contact with the ground from the metatarsal head (MTBH) to the tip of the toe, and the weight is loaded to the ground.
맨발의 발뒤꿈치떼기(heel off) 상태에서는 발뒤꿈치가 지면에서 떨어지면서 중족지관절(MTP, metatarsophalangeal joints)의 신전(extension, 도 7의 (a)에서 가상선 화살표 방향의 움직임)이 일어난다. 그리고 이와 동시에 발뒤꿈치가 내측으로 회전하는 움직임인 내번(inversion, 도 7의 (b)에서 가상선 곡선화살표(i) 방향의 움직임)과 내측으로 가까워지는 움직임인 내전(adduction, 도 7의 (b)에서 가상선 직선화살표(a) 방향의 움직임)이 발생한다. In the heel off state of the bare foot, the heel falls off the ground, causing the extension of the metatarsophalangeal joints (MTP) (extension (movement in the direction of the imaginary line arrow in FIG. 7(a))). At the same time, at the same time, inward movement (inversion, movement in the direction of the imaginary line curved arrow (i) in FIG. 7(b)), which is a movement in which the heel rotates inward, and adduction (movement) in FIG. 7 (b) ), the movement of the straight line (a) in the virtual line occurs.
도 8의 (a)는 맨발 보행 중 발가락떼기(toe off) 상태의 측면이고, 도 8의 (b)는 맨발 보행 중 발가락떼기(toe off) 상태를 후방(발뒤꿈치 측)에서 본 도면이다.FIG. 8(a) is a side view of a toe off state while walking barefoot, and FIG. 8(b) is a view of a toe off state while walking barefoot from a rear side (heel side).
발가락떼기(toe off) 단계에서는 중족골두(MTBH)가 지면으로부터 떨어지면서 발가락을 통해서만 체중이 지면으로 부하된다. In the toe off phase, the metatarsal head (MTBH) falls off the ground, and only the toes lose weight to the ground.
도 8에 도시한 바와 같이, 발가락떼기(toe off) 시기에는 중족지관절(MTP, metatarsophalangeal joint)이 더욱 신전되면서 발뒤꿈치의 내번(inversion)과 내전(adduction) 움직임이 최대가 된다.As shown in FIG. 8, in the toe off period, metatarsophalangeal joints (MTPs) are further extended and inversion and adduction movements of the heel are maximized.

도 9a의 (a)에 도시한 바와 같이, 만곡이 없는 유연한 평판구조물(flat plate)은 구부러짐에 대한 방향성이 없어 종축면(LP, Longitudinal plane)과 횡축면(TP, Transverse plane)을 따라 상방과 하방으로 모두 쉽게 구부러진다.As shown in (a) of FIG. 9A, the flexible flat plate without curvature has no directionality for bending, and upwards and downwards along the longitudinal plane (LP) and transverse plane (TP). All bends down easily.
도 9a의 (b)는 한 개의 축을 따라 만곡을 주었을 때(zero gaussian curvature) 이와 교차하는 축을 따라 구부러짐(bending)이 제한되는 것을 설명하기 위한 도면이다. 도 9a의 (b)에 도시한 바와 같이, 횡축면(TP)을 따라 상방으로 오목하게 만곡을 주었을 때 이와 교차하는 종축면(LP)에서의 구부러짐(bending)은 제한되며, 특히 하방을 향한 구부러짐이 가장 많이 제한된다.FIG. 9A (b) is a diagram for explaining that bending is limited along an axis intersecting it when a curve is given along one axis (zero gaussian curvature). As shown in FIG. 9A (b), bending is limited in the longitudinal axis LP intersecting the curve when concavely curved upward along the transverse axis TP, and in particular bending downward. This is the most limited.
도 9a의 (c)와 도 9b의 (d)는 서로 교차하는 2개 축을 따라 만곡을 주었을 때 구부러짐(bending)의 방향성을 설명한 도면이다. 9A (C) and 9B (D) are views illustrating the direction of bending when bending along two axes intersecting each other.
도 9a의 (c)에 도시한 바와 같이, 횡축면(TP)을 따른 만곡방향(상방으로 오목)과 종축면(LP)을 따른 만곡방향(하방으로 오목)이 반대일 경우(negative gaussian curvature)에는 종축면과 횡축면에 대한 상방 및 하방 구부러짐(bending)이 모두 제한된다. 반면, 도 9b의 (d)에 도시한 바와 같이, 2개 축에 대한 만곡방향이 동일한 경우(positive gaussian curvature), 예를 들어 종축면(LP)과 횡축면(TP)을 따라 상방으로 모두 오목하면 종축면(LP)과 횡축면(TP) 모두에서 하방으로 구부러짐(bending)이 제한된다.As shown in Fig. 9A (c), when the bending direction along the transverse plane TP (concave upward) and the bending direction along the longitudinal axis LP (concave downward) are opposite (negative gaussian curvature) In both the upper and lower bending of the longitudinal and transverse planes is limited. On the other hand, as shown in (d) of FIG. 9B, when the curved directions for the two axes are the same (positive gaussian curvature), for example, they are both concave upward along the longitudinal axis LP and the transverse axis TP. When the lower surface of the longitudinal axis (LP) and the horizontal axis (TP) both the bending (bending) is limited.
도 9b의 (e)는 급하게 이루어지는 만곡 형상일수록 만곡 축과 교차하는 축에서 만곡방향의 반대방향으로 구부러짐은 더욱 제한됨을 설명하기 위한 도면이다. 도 9b의 (e)에 도시한 바와 같이, 횡축면(TP)을 따라 상방으로 오목한 만곡이 급하게 이루어질수록, 즉 곡률이 클수록 이와 교차하는 종축면(LP)에서 하방을 향한 구부러짐(bending)은 더욱 제한된다.FIG. 9B(e) is a view for explaining that the more the curved shape formed in a hurry, the more the bending in the opposite direction of the curved direction in the axis intersecting the curved axis is further limited. As shown in (e) of FIG. 9B, the more rapidly the concave curve is made upward along the transverse plane TP, that is, the larger the curvature, the more downward bending in the longitudinal axis LP intersecting it becomes more. Is limited.
도 9b의 (f)는 도 9b의 (e)와 동일하게 횡축면(TP)의 곡률을 종축면(LP)의 곡률보다 크게 하고, 횡축면(TP)의 곡률에서 내측부의 곡률(rM)보다 외측부의 곡률(rL)을 더 크게 하여 횡축면(TP)으로 잘라서 본 도면이다. 외측부의 만곡이 내측부보다 급하게 이루어지므로, 종축면(LP)에서 하방을 향한 구부러짐은 외측부가 내측부보다 더욱 제한된다.9B (f), in the same manner as in FIG. 9B (e), the curvature of the transverse axis TP is greater than that of the longitudinal axis LP, and the curvature of the transverse axis TP is greater than the curvature of the inner portion rM. It is a figure seen by cutting the curvature rL of the outer part to a larger horizontal axis TP. Since the curvature of the outer portion is made more steeply than the inner portion, bending toward the downward direction in the longitudinal axis LP is more limited than the inner portion.
곡선의 곡률은 곡선상에 있는 점(point)에서의 곡률로 표현된다. 따라서 2차원상의 평면 곡선(plane curve)의 곡률(curvature) 크기는 각각의 평면 곡선에서 최대곡률값을 갖는 점의 곡률 값으로 비교할 수 있다. 또는 곡선상의 모든 점에서 곡률값을 구하여 그에 대한 평균으로도 비교할 수 있다.The curvature of a curve is expressed as the curvature at a point on the curve. Therefore, the magnitude of the curvature of a two-dimensional plane curve can be compared with the curvature value of a point having a maximum curvature value in each plane curve. Alternatively, the curvature values at all points on the curve can be obtained and compared with the average.

도 12는 본 발명의 제1 실시예의 바닥구조물(5)을 도시한 사시도이고, 도 13은 도 12의 측면도이다. 도 12에서 가상의 선으로 표시한 종축선(5a)들과 횡축선(5b)들은 바닥구조물(5)의 만곡도(곡률)를 표현하기 위해 바닥구조물(5)에 격자선(grid line)을 투영(projection)한 것이다. 도 12에 도시된 종축선(5a)들은 지면을 향하여 수직방향으로 바닥구조물(5)에 투영된 선들이며, 발의 종축(LA)과 나란한 선들이다. 도 12에 도시된 횡축선(5b)들은 직선 AB(도 13에서 도시함)에 대하여 직각방향으로 바닥구조물(5)에 투영된 선들이며, 발의 횡축(TA)과 나란한 선들이다. 도 13에 도시된 직선 AB는 바닥구조물(5)의 후방부 끝지점(PA)과 지면을 지지하는 프론트부(11)의 후방부 끝지점(PB)을 이은 선으로 발의 종축과 나란한 직선이다. 이러한 종축선(5a)들과 횡축선(5b)들은 격자선(grid line)을 이루며 이를 투영(projection)한 것이다.12 is a perspective view showing the floor structure 5 of the first embodiment of the present invention, and FIG. 13 is a side view of FIG. 12. In FIG. 12, the vertical axis lines 5a and the horizontal axis lines 5b indicated by virtual lines project a grid line on the floor structure 5 to express the curvature (curvature) of the floor structure 5. (projection). The vertical axis lines 5a shown in FIG. 12 are lines projected on the floor structure 5 in the vertical direction toward the ground, and are lines parallel to the vertical axis LA of the foot.

The straight line AB shown in FIG. 13 is a straight line parallel to the longitudinal axis of the foot with a line connecting the rear end point PA of the floor structure 5 and the rear end point PB of the front part 11 supporting the ground. The vertical axis lines 5a and the horizontal axis lines 5b form a grid line and project it.
본 발명의 제1 실시예의 바닥구조물(5)은, 도 12와 도 13에 도시한 바와 같이, 프론트부(11), 밴딩부(13), 그리고 리어부(15)를 포함한다.The floor structure 5 of the first embodiment of the present invention includes a front portion 11, a bending portion 13, and a rear portion 15, as shown in Figs.
프론트부(11)는 하중반응기(loading response)에 굽 높은 신발의 전방측이 지면에 지지되는 부분이다. The front portion 11 is a portion in which the front side of shoes with high heels in the loading response is supported on the ground.
본 발명의 제1 실시예에서는 프론트부(11)가 지면을 지지하는 부분 중 일부분만 커버하는 크기로 이루어지는 예를 도시하여 설명하기로 한다. 본 발명의 제1 실시예의 바닥구조물(5)은 프론트부(11)가 지면을 지지하는 부분 중 일부분만 커버하는 크기로 이루어질 때, 도 11에 도시한 바와 같이 별도의 보조부재(Sb1, Sb2)들이 프론트부(11)에 부착될 수 있다.In the first embodiment of the present invention, an example in which the front portion 11 is made of a size that covers only a portion of the portion supporting the ground will be described and described. When the floor structure 5 of the first embodiment of the present invention is made of a size in which the front portion 11 covers only a portion of the portion supporting the ground, separate auxiliary members Sb1 and Sb2 as shown in FIG. These may be attached to the front portion 11.
프론트부(11)는 밴딩부(13)에 연장되는 후방 부분이 평면도로 볼 때 전방을 향해 오목한 라운드 모양의 경계를 가지는 지면 지지 경계선(BL)을 포함할 수 있다.The front portion 11 may include a ground support boundary line BL having a concave round-shaped boundary toward the front when the rear portion extending to the bending portion 13 is viewed in plan view.
이러한 프론트부(11)의 지면 지지 경계선(BL)은 프론트부(11)가 지면에 견고하게 지지되도록 하여 입각기에 보행의 안정성을 향상시킨다. 또한 프론트부(11)는 지면 지지 경계선(BL)의 형상으로 인해 구부러짐(bending)이 제한되어 신발 형상을 유지할 수 있다. The ground support boundary line BL of the front portion 11 allows the front portion 11 to be firmly supported on the ground, thereby improving walking stability in the stance phase. In addition, the front portion 11 may be bent due to the shape of the ground support boundary line BL to maintain the shape of the shoe.
밴딩부(13)는 지면과 반대 방향으로만 구부러지는 일방향밴딩부 또는 지면 반대 방향으로 오목한 곡면을 이루는 밴딩곡면부로 이루어질 수 있다.The bending portion 13 may be formed of a one-way bending portion that is bent only in a direction opposite to the ground or a bending curved portion forming a concave curved surface in the direction opposite to the ground.
밴딩부(13)는 프론트부(11)의 지면 지지 경계선(BL)에서 연장되어 중족지관절(MTP)의 후방부에 위치하는 것이 바람직하다. 다시 말하면, 밴딩부(13)는 프론트부(11)의 지면 지지 경계선(BL)을 기준으로 발뒤꿈치 측에 위치하는 것이 바람직하다. 즉, 밴딩부(13)는 프론트부(11)의 지면 지지 경계선(BL) 및 중족부(MF)와 전족부(FF)가 이루는 경계선(도 13과 도 15에서 점선으로 표시함)의 사이에 위치할 수 있다.It is preferable that the bending portion 13 extends from the ground support boundary line BL of the front portion 11 and is located at the rear portion of the metatarsal joint MTP. In other words, the bending portion 13 is preferably located on the heel side with respect to the ground support boundary line BL of the front portion 11. That is, the bending portion 13 is located between the ground support boundary line BL of the front portion 11 and the boundary line formed by the midfoot portion MF and the forefoot portion FF (indicated by a dotted line in FIGS. 13 and 15). can do.
밴딩부(13)는 밴딩곡면부로 이루어져 지면 방향을 향하는 방향으로 구부러짐이 제한되며 지면과 반대 방향으로 유연하게 구부러질 수 있다. 즉, 밴딩부(13)는 지면과 반대 방향을 향해 일방향으로 구부러질 수 있다.The bending portion 13 is formed of a bending curved portion, and bending is limited in a direction toward the ground direction, and the bending portion 13 can be flexibly bent in a direction opposite to the ground. That is, the bending portion 13 may be bent in one direction toward the direction opposite to the ground.
밴딩부(13)는 지면 반대 방향으로 오목한 곡면을 이루는 밴딩곡면부로 이루어지는 것이 바람직하다. 따라서, 밴딩부(13)에서 밴딩부 종축 중심선(13ac)과 나란한 종축선(13a, 도 12에서 길이 방향으로 표시된 가상의 선)들과 밴딩부 횡축 중심선(13bc)과 나란한 횡축선(13b, 도 12에서 폭 방향으로 표시된 가상의 선)들은 지면 반대 방향으로 오목하게 이루어지는 곡률을 가진다. 본 발명의 제1 실시예의 설명에서 밴딩부 종축 중심선(13ac)은 밴딩부(13)에서 발의 종축(LA)을 지나는 중심선이며, 밴딩부 횡축 중심선(13bc)은 발의 횡축(TA)과 나란하면서 밴딩부(13)의 가운데 부분을 폭 방향으로 지나는 중심선이다.The bending portion 13 is preferably made of a bending curved portion forming a concave curved surface in a direction opposite to the ground. Accordingly, in the bending portion 13, the vertical axis 13a (the virtual line shown in the longitudinal direction in FIG. 12) parallel to the vertical axis 13b of the bending portion and the horizontal axis 13b parallel to the bending center horizontal axis 13bc, FIG. The imaginary lines indicated in the width direction at 12) have a curvature that is concave in the opposite direction to the ground. In the description of the first embodiment of the present invention, the vertical axis of the bending portion 13ac is a central line passing through the vertical axis LA of the foot in the bending portion 13, and the horizontal axis of the bending portion 13bc is parallel to the horizontal axis of the foot (TA). It is a centerline passing in the width direction of the center portion of the part (13).
밴딩부 횡축 중심선(13bc)의 곡률(r2)은 밴딩부 종축 중심선(13ac)의 곡률(r1)보다 더 크게 이루어지는 것이 바람직하다. 곡률이란 한 점이 일정한 속도로 곡선을 따라 이동할 때 생기는 접선의 기울기의 변화를 의미하므로 평면 곡선(plane curve)의 곡률은 곡선상에 있는 점(point)에서의 곡률로 표현된다. 따라서 본 발명의 설명에서 "밴딩부 횡축 중심선(13bc)의 곡률(r2)이 밴딩부 종축 중심선(13ac)의 곡률(r1)보다 크다"라고 함은 밴딩부 횡축 중심선(13bc)에서 최대곡률값을 갖는 점의 곡률 값이 밴딩부 종축 중심선(13ac)에서 최대곡률값을 갖는 점의 곡률 값보다 큰 것을 의미한다. 또는 밴딩부 횡축 중심선(13bc)의 곡률값의 평균(average)이 밴딩부 종축 중심선(13ac)의 곡률값의 평균(average)보다 큰 것을 의미한다. 또한, 이러한 곡률값의 크기를 비교함에 있어서 밴딩부(13)의 경계부, 특히 프론트부(11)와의 경계부나 양측 끝단에서의 곡률값은 제외됨이 당연하다.It is preferable that the curvature r2 of the center line 13bc of the bending portion is greater than the curvature r1 of the center line 13ac of the bending portion vertical axis. Curvature refers to the change in the slope of the tangent line that occurs when a point moves along a curve at a constant speed, so the curvature of a plane curve is expressed as the curvature at a point on the curve. Therefore, in the description of the present invention, "the curvature r2 of the horizontal axis of the bending section 13bc is greater than the curvature r1 of the vertical axis of the bending section 13ac" means that the maximum curvature value at the bending center axis 13b It means that the curvature value of the point having is greater than the curvature value of the point having the maximum curvature value at the center line 13ac of the vertical axis of the bending portion. Or, it means that the average value of the curvature of the bending part horizontal axis center line 13bc is greater than the average value of the curvature value of the bending part vertical axis center line 13ac. In addition, in comparing the magnitudes of the curvature values, it is natural that the curvature values of the boundary portion of the banding portion 13, in particular, the boundary portion with the front portion 11 or the both ends are excluded.
이와 같이, 밴딩부 종축 중심선(13ac)의 곡률(r1)보다 밴딩부 횡축 중심선(13bc)의 곡률(r2)이 더 크게 이루어지면, 도 9b의 (e)에서 설명하였듯이 종축에서 하방을 향한 구부러짐(bending)은 더욱 제한된다. 밴딩부(13)는 입각중기(midstance) 이후 발뒤꿈치떼기(heel off) 및 발가락떼기(toe off) 시기에 지면 반대 방향으로 오목하게 구부러지고, 지면 방향으로 구부러짐이 제한된다. 다시 말하면, 밴딩부(13)는 중족지관절(MTP, metatarsophalangeal joint)의 신전(extension)의 움직임과 같은 방향으로 구부러지고 중족지관절(MTP, metatarsophalangeal joint)의 굴곡(flexion)의 움직임과 같은 방향으로 구부러지는 것이 제한된다. As described above, when the curvature r2 of the horizontal axis of the central axis of the bending portion 13bc is greater than the curvature r1 of the central axis of the vertical axis of the bending portion 13ac, as illustrated in (e) of FIG. 9B, the downward bending from the vertical axis ( bending) is more limited. The bending portion 13 is concavely bent in the opposite direction to the ground at the time of heel off and toe off after the midstance, and bending in the ground direction is limited. In other words, the bending portion 13 is bent in the same direction as the movement of the extension of the metatarsophalangeal joint (MTP), and in the same direction as the movement of the flexion of the metatarsophalangeal joint (MTP). It is limited to bend.
이러한 밴딩부(13)는 보행 중 입각중기(midstance) 이후 발뒤꿈치떼기(heel off)과 발가락떼기(toe off) 시기에 중족지관절(MTP, metatarsophalangeal joint)의 신전(extension)의 움직임과 같은 방향으로 구부러지는 유연성(flexibility)을 가진다. 따라서 맨발의 보행과 마찬가지로 굽 높은 신발을 신은 상태에서도 보행자는 발뒤꿈치떼기(heel off)과 발가락떼기(toe off) 시기에 자연스러운 보행을 할 수 있다. The banding portion 13 is in the same direction as the movement of the extension of the metatarsophalangeal joint (MTP) during heel off and toe off after walking midstance during walking. It has the flexibility to bend. Therefore, like walking barefoot, even in high-heeled shoes, pedestrians can walk naturally during heel off and toe off.
또한, 밴딩부(13)는 보행 중 발뒤꿈치떼기(heel off)과 발가락떼기(toe off) 시기에 맨발의 움직임과 같은 방향으로 구부러지면서 리어부(15)도 상방으로 움직이므로 발뒤꿈치가 발 고정부(1)에서 빠지는 것을 방지하는 역할을 한다.In addition, the banding portion 13 is bent in the same direction as the movement of the bare feet during heel off and toe off during walking, and the rear portion 15 also moves upwards, so that the heel is raised. It serves to prevent the government (1) from falling out.
착용자가 뒷굽이 높은 신발을 신게 되면, 족저근막(PF, plantar fascia)이 팽팽하게 당겨져 중족지관절(MTP, metatarsophalangeal joint)을 굴곡(flexion)시키는 힘이 발생하게 된다(도 26에서 도시함). 특히 유각기(swing phase) 동안에는 신발의 바닥이 지면에서 떨어져 있으므로 중족지관절(MTP, metatarsophalangeal joint)의 굴곡(flexion)에 의하여 신발의 앞 끝이 지면 쪽으로 구부러질 수 있다.When the wearer wears high-heeled shoes, the plantar fascia (PF) is pulled taut and the force that flexes the metatarsophalangeal joint (MTP) occurs (shown in Figure 26). In particular, during the swing phase, the front end of the shoe may be bent toward the ground by flexion of the metatarsophalangeal joint (MTP) because the bottom of the shoe is off the ground.
본 발명의 밴딩부(13)는 유각기(swing phase)동안 지면 방향으로 구부러짐이 제한되므로 중족지관절(MTP, metatarsophalangeal joint)이 굴곡(flexion)되는 움직임도 제한하게 된다. 따라서 유각기 동안 발가락 들림(toe clearance)이 충분하게 제공되므로, 신발 끝이 지면에 끌리거나 걸리지 않게 되어 안정적인 보행이 이루어진다.Since the bending part 13 of the present invention is restricted in bending in the direction of the ground during the swing phase, the movement of the metatarsophalangeal joint (MTP) is also restricted. Therefore, toe clearance is sufficiently provided during the swing phase, so that the tip of the shoe is not dragged or caught on the ground, thereby ensuring stable walking.
한편, 밴딩부(13)의 내측과 외측의 가장자리 부분은 프론트부(11)와 지면 지지 경계선(BL)의 양측면으로 더욱 연장되는 지지보강부(13e, 13f)를 형성할 수 있다. 이러한 밴딩부(13)의 지지보강부(13e, 13f)는 라운드 모양의 지면 지지 경계선(BL)의 양측면으로부터 상방으로 연장되므로 지면의 반대 방향으로 오목하게 구부러짐을 허용하지만 지면 방향으로 구부러지는 것을 더욱 제한할 수 있다.On the other hand, the inner and outer edge portions of the bending portion 13 may form support reinforcement portions 13e, 13f that extend further to both sides of the front portion 11 and the ground support boundary line BL. The support reinforcing portions 13e and 13f of the banding portion 13 extend upward from both sides of the round-shaped ground support boundary line BL, thereby allowing concave bending in the opposite direction of the ground, but further bending in the ground direction Can be limited.
따라서 본 발명의 바닥구조물(5)은 발의 움직임 중 발뒤꿈치떼기(heel off) 및 발가락떼기(toe off) 시기에는 중족지관절(MTP, metatarsophalangeal joint)의 신전(extension)의 움직임을 더욱 용이하게 허용한다. 또한, 본 발명의 바닥구조물(5)은 유각기(swing phase)에는 중족지관절(MTP, metatarsophalangeal joint)의 굴곡(flexion)의 움직임을 더욱 제한할 수 있다. 따라서 굽 높은 신발을 신은 보행자는 더욱 안정성을 가지는 보행을 할 수 있다.Therefore, the floor structure 5 of the present invention allows the movement of the extension of the metatarsophalangeal joint (MTP) more easily during the heel off and toe off periods of the foot movement. do. In addition, the floor structure 5 of the present invention can further limit the movement of the flexion of the metatarsophalangeal joint (MTP) in the swing phase. Therefore, pedestrians wearing high-heeled shoes can walk more stably.
이러한 본 발명은 바닥구조물(5)이 간단한 구조로 이루어져 생산 비용 및 제조 비용을 줄일 수 있다. 즉, 본 발명의 바닥구조물(5)은 입각중기(midstance) 이후 발뒤꿈치떼기(heel off)과 발가락떼기(toe off) 시기에 중족지관절(MTP, metatarsophalangeal joint)의 신전(extension)의 움직임을 최대한 확보할 수 있다. 이와 동시에 본 발명의 바닥구조물(5)은 유각기에서 중족지관절(MTP, metatarsophalangeal joint)의 굴곡(flexion)의 움직임을 제한하는 구조를 가지면서도 간단한 구조로 이루어져 굽 높은 신발에 용이하게 적용할 수 있고 제조 비용을 줄일 수 있다.In the present invention, the floor structure 5 is made of a simple structure, thereby reducing production cost and manufacturing cost. That is, the floor structure (5) of the present invention moves the movement of the extension of the metatarsophalangeal joint (MTP) at the time of heel off and toe off after midstance. It can be secured as much as possible. At the same time, the floor structure (5) of the present invention has a structure that restricts the movement of flexion of the metatarsophalangeal joint (MTP) in the swing phase, and has a structure that is simple and can be easily applied to high-heeled shoes. And reduce manufacturing costs.
도 14는 제1 실시예에서 밴딩부(13)의 횡단면을 전면에서 바라본 도면으로, 밴딩부 횡축 중심선(13bc)의 곡률(r2)을 외측 부분(13c)의 곡률(r3)과 내측 부분(13d)의 곡률(r4)로 분할하여 도시하였다. 도 15는 제1 실시예에서 바닥구조물(5)의 종축을 따라 잘라서 본 도면이다.14 is a view of the cross section of the bending portion 13 in the first embodiment as viewed from the front, the curvature r2 of the center line 13bc of the bending portion is curvature r3 and inner portion 13d of the outer portion 13c ) Divided by the curvature (r4). FIG. 15 is a view cut along the longitudinal axis of the floor structure 5 in the first embodiment.
본 발명의 제1 실시예에서 밴딩부(13)는 외측 부분(13c)의 곡률(r3)이 내측 부분(13d)의 곡률(r4)에 비해 더 크게 이루어지는 것이 바람직하다. 이러한 밴딩부(13)는 내측 부분(13d)이 외측 부분(13c)보다 더 유연함을 의미한다. In the first embodiment of the present invention, the bending portion 13 is preferably made to have a larger curvature r3 of the outer portion 13c than a curvature r4 of the inner portion 13d. The bending portion 13 means that the inner portion 13d is more flexible than the outer portion 13c.
입각중기(midstance) 이후에는 신발의 뒷굽(9)이 지면과 떨어지게 되므로 바닥구조물(5)의 프론트부(11)만이 지면과 접촉하여 체중이 부하되게 된다. 그러므로 발뒤꿈치떼기(heel off)와 발가락떼기(toe off) 시기에는 프론트부(11)가 지면에 고정된 상태에서 바닥구조물(5)의 나머지 후방부위에서 움직임이 발생한다. 즉, 밴딩부(13)에서 내측 부분(13d)과 외측 부분(13c)의 유연성 차이로 리어부(15)의 움직임의 방향이 결정된다.After the midstance, since the heel 9 of the shoe falls off the ground, only the front portion 11 of the floor structure 5 comes into contact with the ground, and the weight is loaded. Therefore, during the heel off and toe off periods, movement occurs in the remaining rear portion of the floor structure 5 while the front portion 11 is fixed to the ground. That is, the direction of movement of the rear portion 15 is determined by a difference in flexibility between the inner portion 13d and the outer portion 13c in the bending portion 13.
따라서 본 발명의 바닥구조물(5)은 보행주기 중 발뒤꿈치떼기(heel off)와 발가락떼기(toe off) 구간에서 밴딩부(13)에서 후방으로 연장된 리어부(15)가 프론트부(11)를 기준으로 상방으로 올라감(도 15에서 가상선 화살표 방향)과 동시에 내측(M) 방향으로 회전(twisting movement, 도 14에서 가상선 곡선 화살표) 및 이동(도 14에서 가상선 직선 화살표)하게 된다. 따라서 보행주기 중 발뒤꿈치떼기(heel off)과 발가락떼기(toe off) 구간에서 리어부(15)는 발뒤꿈치의 내번(inversion)과 내전(adduction) 방향과 동일한 방향으로 움직이게 된다. 즉, 이와 같이 밴딩부(13)가 외측 부분(13c)의 곡률(r3)이 내측 부분(13d)의 곡률(r4)에 비해 더 큰 구조는 보행자가 굽 높은 신발을 신은 경우에도 발뒤꿈치의 움직임과 같은 방향으로 바닥구조물(5)의 리어부(15)가 움직일 수 있다. 따라서 본 발명의 바닥구조물(5)이 적용된 굽 높은 신발을 신은 보행자는 더욱 안정성이 있는 보행을 할 수 있다.Therefore, in the floor structure 5 of the present invention, the rear portion 15 extending rearward from the bending portion 13 in the heel off and toe off section during the walking cycle has a front portion 11. Based on the upward movement (in the direction of the imaginary line arrow in FIG. 15) and at the same time, rotation (twisting movement, the imaginary line curved arrow in FIG. 14) and movement (in the direction of the imaginary line arrow in FIG. 14) are performed. Therefore, in the heel off and toe off section during the walking cycle, the rear portion 15 moves in the same direction as the inversion and adduction directions of the heel. That is, the structure in which the bending portion 13 has a larger curvature r3 of the outer portion 13c than the curvature r4 of the inner portion 13d has heel movement even when a pedestrian wears high-heeled shoes. The rear portion 15 of the floor structure 5 may move in the same direction. Therefore, a pedestrian with high-heeled shoes to which the floor structure 5 of the present invention is applied can walk more stably.

In addition, the floor structure of the present invention can be processed with a synthetic resin material of the same material, thereby reducing manufacturing costs.
도 16은 본 발명의 제1 실시예를 설명하기 위해 굽 높은 신발을 착용한 상태에서 보행할 때 밴딩부(13)가 작용하는 과정을 설명하기 위한 도면이다. 16 is a view for explaining the process of the bending portion 13 when walking while wearing high-heeled shoes to explain the first embodiment of the present invention.
도 16의 (a)는 보행 주기 중 발뒤꿈치접지(heel strike) 상태를 도시한 도면이다. 도 16 (a)는 중족지관절(MTP, metatarsophalangeal joint)의 후방 또는 지면을 지지하는 프론트부(11)의 후방에 있는 밴딩부(13)가 지면 방향으로 구부러지지 않은 상태를 나타낸다. 물론, 밴딩부(13)는 유각기(swing phase)에서도 지면 방향으로 구부러지지 않는다. 즉, 본 발명의 바닥구조물(5)은 밴딩부 종축 중심선(13ac)의 곡률(r1)보다 밴딩부 횡축 중심선(13bc)의 곡률(r2)이 더 크게 이루어지므로 발뒤꿈치접지(heel strike) 및 유각기(swing phase)에 지면 방향으로 구부러지지 않는다. 또한, 본 발명의 바닥구조물(5)은 밴딩부(13)의 지지보강부(13e, 13f)에 의해 발뒤꿈치접지(heel strike) 및 유각기(swing phase)에 밴딩부(13)와 프론트부(11)가 지면 방향으로 구부러지는 것이 더욱 제한된다. 다시 말하면, 본 발명의 바닥구조물(5)이 적용된 굽 높은 신발을 신고 보행을 할 때, 족저근막이 당겨지면서 발가락들이 지면방향으로 굴곡(flexion)되는 힘이 발생하지만 밴딩부(13)의 작용으로 밴딩부(13)와 프론트부(11)가 지면 방향으로 구부러지는 것을 방지한다. 16A is a view showing a heel strike state during a walking cycle. FIG. 16(a) shows a state in which the bending portion 13 at the rear of the metatarsophalangeal joint (MTP) or the front portion 11 supporting the ground is not bent toward the ground. Of course, the bending portion 13 is not bent in the ground direction even in the swing phase. That is, the floor structure (5) of the present invention has a greater curvature (r2) of the bending center transverse center line (13bc) than the curvature (r1) of the bending center axis (13ac), so heel strike and play It does not bend to the ground during each swing phase. In addition, the floor structure 5 of the present invention is a bending portion 13 and a front portion on a heel strike and swing phase by the support reinforcement portions 13e, 13f of the bending portion 13. It is further limited that 11 is bent in the ground direction. In other words, when walking with high-heeled shoes to which the floor structure 5 of the present invention is applied, while the plantar fascia is pulled, toes are flexed in the direction of the ground, but due to the action of the bending portion 13 The bending portion 13 and the front portion 11 are prevented from bending in the ground direction.
따라서 본 발명의 제1 실시예의 바닥구조물(5)은 유각기(swing phase) 및 발뒤꿈치접지(heel strike) 시기에 중족지관절(metatarsophalangeal joint)의 신전(extension) 상태를 유지하도록 하여 안정성 있는 보행을 가능하게 한다.Therefore, the floor structure 5 of the first embodiment of the present invention is stable walking by maintaining the extension state of the metatarsophalangeal joint at the time of swing phase and heel strike. Makes it possible.
그리고 밴딩부(13)는 발뒤꿈치접지(heel strike) 직후의 하중반응기(loading response)에 프론트부(11)가 지면을 지지하게 되는데 이 때에도 구부러짐이 제한된다.In addition, the bending portion 13 supports the ground by the front portion 11 in a loading response immediately after a heel strike, but bending is limited at this time.
도 16의 (b)는 보행 주기 중 입각중기(midstance) 상태를 도시한 도면이다. 도 16의 (b)는 프론트부(11)가 지면을 지지하고 있는 상태이다. 밴딩부(13)는 입각중기(midstance)에 유각기(swing phase) 및 발뒤꿈치접지(heel strike) 시기와 마찬가지로 구부러지지 않는다.FIG. 16(b) is a view showing a midstance state during a walking cycle. 16B is a state in which the front portion 11 supports the ground. The bending portion 13 is not bent as in the swing phase and the heel strike period in the midstance.
도 16의 (c)는 보행 주기 중 발뒤꿈치떼기(heel off) 상태를 도시한 도면이다. 도 16의 (c)는 중족지관절(MTP, metatarsophalangeal joint)의 후방 또는 지면을 지지하는 프론트부(11)의 후방에 있는 밴딩부(13)가 지면 반대 방향으로 구부러지는 상태를 나타낸다. 발뒤꿈치떼기(heel off) 시기에는 발뒤꿈치가 지면으로부터 떨어지지만 중족골두(MTBH)를 통하여 지면으로 체중이 계속 부하된다. 따라서 지면 지지 경계선(BL)의 전방에 위치하는 프론트부(11)는 지면과 붙어있게 되어 구부러지지 않으며, 지면 지지 경계선(BL)의 후방에 위치하는 밴딩부(13)가 구부러지게 된다.16(c) is a view showing a heel off state during a gait cycle. FIG. 16(c) shows a state in which the bending portion 13 at the rear of the metatarsophalangeal joint (MTP) or the front portion 11 supporting the ground is bent in the opposite direction to the ground. During the heel off period, the heel falls off the ground, but the weight continues to be loaded into the ground through the metatarsal head (MTBH). Therefore, the front portion 11 positioned in front of the ground support boundary line BL is not bent because it is attached to the ground, and the bending portion 13 positioned behind the ground support boundary line BL is bent.
본 발명의 밴딩부(13)는 종축과 횡축에 대한 만곡방향이 동일하므로 발뒤꿈치떼기(heel off)시기에 상방으로 오목한 곡면을 이루며 구부러진다. 또한, 밴딩부(13)는 발뒤꿈치떼기(heel off)시기에 밴딩부 종축 중심선(13ac)의 곡률(r1)보다 밴딩부 횡축 중심선(13bc)의 곡률(r2)이 더 큰 구조에 의해 횡축과 교차하는 종축을 따라 지면 방향으로 구부러짐(bending)은 더욱 제한된다.The bending portion 13 of the present invention has the same curved direction with respect to the vertical axis and the horizontal axis, and thus bends while forming a concave curved surface upward at the time of heel off. In addition, the bending portion 13 has a greater curvature (r2) than the curvature (r1) of the bending center axis (13ac) of the bending center axis (13ac) at the heel off (heel off) period, and the transverse axis and Bending in the direction of the ground along the intersecting longitudinal axis is further limited.
또한 리어부(15)가 밴딩부 횡축 중심선(13bc)에서 외측 부분(13c)의 곡률(r3)이 내측 부분(13d)의 곡률(r4)에 비해 더 큰 구조에 의해 발뒤꿈치의 내번(inversion)과 내전(adduction)의 움직임에 대응하여 움직인다. 따라서 본 발명의 제1 실시예의 바닥구조물(5)은 맨발에서의 보행과 마찬가지로 중족지관절(MTP, metatarsophalangeal joint)의 신전(extension)의 움직임과 같은 방향으로 구부러지고 동시에 발의 내번(inversion)과 내전(adduction) 움직임과 같은 방향으로 구부러진다. 그러므로 본 발명의 제1 실시예는 굽 높은 신발을 착용하고 보행하여도 안정성 있는 보행이 이루어진다. In addition, the inversion of the heel due to a structure in which the rear portion 15 has a greater curvature r3 of the outer portion 13c than the bending portion transverse centerline 13bc compared to the curvature r4 of the inner portion 13d. It moves in response to the movement of and adduction. Therefore, the floor structure 5 of the first embodiment of the present invention is bent in the same direction as the movement of the extension of the metatarsophalangeal joint (MTP), similar to walking on the bare feet, and at the same time inversion and pronation of the foot. (adduction) Bends in the same direction as the movement. Therefore, in the first embodiment of the present invention, stable walking is achieved even when walking while wearing high-heeled shoes.
또한, 이러한 본 발명의 제1 실시예의 바닥구조물(5)은 밴딩부(13)가 지면 반대 방향으로 쉽게 구부러지면서 리어부(15)가 맨발의 보행에서와 같은 방향으로 발뒤꿈치가 이동하여 발뒤꿈치에서 신발이 이탈되는 것을 방지할 수 있다. In addition, the floor structure 5 of the first embodiment of the present invention, the bending portion 13 is easily bent in the opposite direction to the ground, and the rear portion 15 moves the heel in the same direction as in barefoot walking, and the heel moves. Can prevent the shoes from falling off.
도 17은 종래의 굽 높은 신발과 본 발명의 제1 실시예의 굽 높은 신발을 신은 경우 발의 후방에서 보아 발뒤꿈치의 움직임에 대응하는 바닥구조물(5)의 움직임을 비교하여 설명하는 도면이다.17 is a view for comparing and explaining the movement of the floor structure 5 corresponding to the movement of the heel when viewed from the rear of the foot when the high-heeled shoes and the high-heeled shoes of the first embodiment of the present invention are worn.
도 17의 (a)는 종래의 굽 높은 신발을 신은 상태에서 발뒤꿈치떼기(heel off) 시기에 발뒤꿈치의 내번(inversion)과 내전(adduction)의 움직임이 발생할 때, 신발의 바닥구조물과 발뒤꿈치가 서로 떨어지는 상태를 보여준다. 발뒤꿈치떼기(heel off) 시기에는 뒷굽(9)이 지면에서 떨어지므로 지면(G)을 기준으로 발뒤꿈치와 바닥구조물의 리어부(15)가 서로 다르게 움직인다. 종래의 바닥구조물은 유연성이 부족하고 구부러지더라도 상방으로만 구부러지므로 발뒤꿈치의 움직임과 바닥구조물의 움직임은 일치하지 않게 된다. 즉, 도 17의 (a)에서 도시한 바와 같이 발뒤꿈치의 축(AH)은 뒷굽(9)의 축(AHS)과 일치하지 않게 된다.Figure 17 (a) is a heel inversion (heel off) in the state of wearing a conventional high-heeled shoes when heel inversion (inversion) and adduction (adduction) movement occurs, the bottom structure of the shoe and the heel Shows the states that fall off each other. In the heel off period, the heel 9 and the heel and the rear portion 15 of the floor structure move differently based on the ground G because the heel 9 falls off the ground. Conventional floor structures lack flexibility and are only bent upward even when bent, so the movement of the heel and the movement of the floor structure do not match. That is, as shown in Fig. 17 (a), the axis AH of the heel does not coincide with the axis AHS of the heel 9.
반면, 도 17의 (b)는 본 발명의 제1 실시예의 굽 높은 신발을 신은 상태에서 발뒤꿈치떼기(heel off) 시기에 바닥구조물(5)의 리어부(15)가 발뒤꿈치의 움직임과 동일한 방향으로 움직이는 상태를 보여준다. 본 발명의 제1 실시예의 리어부(15)는 상술한 제1 실시예의 밴딩부(13)의 작용으로 상방으로 움직이는 것이 용이하고 동시에 발뒤꿈치의 내번(도 17의 (b)에서 가상선 곡선 화살표(i))과 내전(도 17의 (b)에서 가상선 직선 화살표(a))의 움직임에 대응하여 내측방향으로 회전 및 이동한다. 따라서 발뒤꿈치의 축(AH)과 뒷굽(9)의 축(AHS)은 서로 일치하게 되어 보행의 안정성을 향상시킬 수 있다.On the other hand, FIG. 17(b) shows that the rear portion 15 of the floor structure 5 is the same as the movement of the heel in the heel off period in the high-heeled shoes of the first embodiment of the present invention. It shows the state of movement in the direction. The rear portion 15 of the first embodiment of the present invention is easy to move upward by the action of the banding portion 13 of the first embodiment described above, and at the same time, the curve of the heel line (in FIG. 17(b) is an imaginary curve arrow) (i)) and civil war (in FIG. 17(b), the rotation and movement in the inner direction correspond to the movement of the linear arrow (a). Therefore, the axis of the heel (AH) and the axis of the heel (AHS) coincide with each other, thereby improving walking stability.
도 18은 본 발명의 제2 실시예를 설명하기 위해 도시한 도면이다. 도 19는 도 18의 바닥구조물(5)의 밴딩부(13)를 횡축 중심선을 따라 잘라서 본 단면도이다. 도 20은 도 18의 바닥구조물(5)을 종축 중심선을 따라 잘라서 본 단면도이다. 도 21은 제2 실시예에서 보조부재(Sb)를 부착한 도면이다. 본 발명의 제2 실시예는 제1 실시예와 비교하여 다른 점만을 설명하고 동일한 부분은 그의 설명으로 대치하기로 한다.18 is a view for explaining a second embodiment of the present invention. 19 is a cross-sectional view of the bending portion 13 of the floor structure 5 of FIG. 18 taken along the horizontal axis. 20 is a cross-sectional view of the floor structure 5 of FIG. 18 taken along the longitudinal axis. 21 is a view to which the auxiliary member (Sb) is attached in the second embodiment. In the second embodiment of the present invention, only the differences from the first embodiment will be described, and the same parts will be replaced by the description thereof.
