Description

쿠션기능을 구비한 신발 밑창Shoe sole with cushioning function
본 발명은 쿠션기능을 구비한 신발 밑창에 관한 것으로, 더욱 상세하게는 밑창 본체의 외면 구조를 변경하여 쿠션기능을 배가시키는 신발 밑창에 관한 것이다.The present invention relates to a shoe sole having a cushion function, and more particularly, to a shoe sole that doubles the cushion function by changing the outer surface structure of the sole body.
일반적으로 신발은 2개의 주요 요소인, 갑피(upper) 및 밑창(sole) 구조물을 포함한다. 갑피는 밑창 구조물에 고정되고, 안락하고 확실하게 발을 수용하기 위한 신발 내부의 빈 공간을 제공한다.Footwear generally includes two main elements: an upper and a sole structure. The upper is secured to the sole structure and provides a void inside the shoe for comfortably and securely receiving the foot.
갑피는 발의 내측 측부(medial side) 및 외측 측부(lateral side)를 따라서, 그리고 발의 뒤꿈치까지, 발의 발등(instep)과 발가락을 감싸는 것이다. The upper covers the instep and toes of the foot along the medial and lateral sides of the foot and up to the heel of the foot.
밑창 구조물은 갑피의 하부 표면에 고정된 것이다. 이러한 밑창은 갑피와 지면 사이에 배치된다. 예를 들어, 밑창 구조물은 중간창(midsole) 및 바닥창(outsole)을 포함한다.The sole structure is secured to the lower surface of the upper. This outsole is disposed between the upper and the ground. For example, a sole structure includes a midsole and an outsole.
중간창은 도보, 달리기, 및 다른 보행 활동 중에 지면 반력(reaction force)을 감소시켜 발과 다리에 가해지는 응력을 줄이기 위한 재료로 형성된 것이다.The midsole is formed of a material intended to reduce the stress on the foot and leg by reducing ground reaction forces during walking, running, and other ambulatory activities.
바닥창은 중간창의 하부 표면에 고정되고, 내구적인 그리고 내마모성인 재료로 형성된 밑창 구조물의 지면-결합 부분을 형성한다.The outsole is secured to the lower surface of the midsole and forms the ground-engaging portion of the sole structure formed from a durable and wear-resistant material.
신발의 밑창은 발의 앞꿈치를 지지하는 앞굽 부분과 뒤꿈치를 지지하는 뒤굽 영역으로 구분될 수 있다. 이처럼 앞꿈치를 지지하는 앞굽 부분과 뒤꿈치를 지지하는 뒤굽 부분 사이의 하부는 발바닥 앞뒤 사이의 오목한 부분을 지지하는 것으로서, 앞뒤 굽 부분보다 지면으로부터 떠있는 구조로 마련된다.The outsole of a shoe may be divided into a front heel portion supporting the heel of the foot and a heel region supporting the heel. As such, the lower part between the heel part supporting the forefoot and the heel part supporting the heel supports the concave part between the front and back of the sole, and is provided in a structure floating from the ground than the front and rear heel parts.
더욱이, 신발 밑창은 착용자의 체중에 의해 가해지는 충격의 상당부분이 착용자의 발목과 무릎에 그대로 전해지므로 이를 최소화하기 위해 쿠션력을 향상시키기 위한 기능성 제품이 출시되고 있다.Moreover, since a significant portion of the shock applied by the wearer's weight is transmitted to the wearer's ankles and knees as it is, functional products for improving cushioning power are being released to minimize this.
이러한, 쿠션력을 향상시키기 위한 신발 밑창과 관련된 기술이 한국등록특허 제1278647호에 제안된 바 있다.A technology related to shoe soles for improving cushioning power has been proposed in Korean Patent Registration No. 1278647.
그러나 특허문헌 1은 쿠션력 발생을 위한 별도의 구조물을 신발밑창 내부에 설치하여야 하므로 신발밑창의 구조 및 제조가 복잡해지는 문제점이 있다.However, Patent Document 1 has a problem in that the structure and manufacturing of the shoe sole become complicated because a separate structure for generating a cushioning force must be installed inside the shoe sole.

도 1은 본 발명의 쿠션기능을 구비한 신발 밑창을 도시한 좌측면도이고, 도 2는 본 발명의 쿠션기능을 구비한 신발 밑창을 도시한 우측면도이고, 도 3은 본 발명의 쿠션기능을 구비한 신발 밑창을 도시한 평단면도이고, 도 4는 본 발명의 쿠션기능을 구비한 신발 밑창을 도시한 정면도이며, 도 5는 본 발명의 쿠션기능을 구비한 신발 밑창에서 기둥부가 부가 설치된 상태를 도시한 평단면도이다.1 is a left side view showing a shoe sole having a cushion function of the present invention, FIG. 2 is a right side view showing a shoe sole having a cushion function of the present invention, and FIG. 3 is a shoe sole having a cushion function of the present invention. Fig. 4 is a front view showing a shoe sole having a cushion function according to the present invention, and Fig. 5 shows a state in which a column part is installed in the shoe sole having a cushion function according to the present invention. It is a flat cross section.
도 1 내지 도 5를 참조하면, 본 발명에 의한 쿠션기능을 구비한 신발 밑창(100)은 발이 들어가도록 발 형상을 갖는 신발 본체(도면에 미도시)의 하부에 결합되는 밑창 본체(110)를 포함한다.1 to 5, the shoe sole 100 having a cushion function according to the present invention includes a sole body 110 coupled to the lower part of a shoe body (not shown) having a foot shape so that the foot enters. include
밑창 본체(110)는 도 1 내지 도 4에 도시된 바와 같이 외면을 따라 함몰 형성되어 체중에 의한 가압시 충격을 흡수하면서 쿠션력을 제공하도록 완충부(120)를 포함한다.As shown in FIGS. 1 to 4 , the outsole body 110 includes a shock absorber 120 formed to be recessed along the outer surface to provide a cushioning force while absorbing shock when pressed by the body weight.
즉, 완충부(120)는 밑창 본체(110)의 외면(측면)을 따라 함몰 형성된다.That is, the shock absorber 120 is recessed along the outer surface (side surface) of the sole body 110 .
이때, 완충부(120)는 종단면 형상이 반원홈 형상으로 형성되는 것으로 예시하며, 이에 한정하지 않고 반타원형, 사각형, 사다리꼴형 등으로 변경 실시가 가능하다.At this time, the buffer unit 120 is exemplified as being formed in a semi-circular groove shape in the longitudinal section, but is not limited thereto and may be changed to a semi-elliptical shape, a square shape, a trapezoid shape, or the like.
더욱 상세히 설명하면, 완충부(120)는 밑창 본체(110)의 외면을 따라 함몰 형성되어 충격 흡수와 함께 체중에 의한 가압시 반발에 의한 쿠션력에 의해 걸음걸이가 빨라지게 한다.More specifically, the shock absorber 120 is recessed along the outer surface of the outsole body 110 to absorb shock and speed up the gait due to the cushioning force generated by repulsion when pressed by the body weight.
더욱이, 완충부(120)는 밑창 본체(110)의 외면에서 1.0~2.5cm의 깊이를 갖도록 형성되며, 이에 한정하지 않고 깊이의 변경이 가능하다.Furthermore, the buffer part 120 is formed to have a depth of 1.0 to 2.5 cm on the outer surface of the sole body 110, and the depth can be changed without being limited thereto.
그리고 완충부(120)는 상하부 즉, 밑창 본체(110)의 외면과의 경계 지점에 지탱돌출부가 구비된다. 지탱돌출부는 체중에 의한 우측 또는 좌측의 가압 부위에 대한 변형을 최소화하게 된다. 즉, 신발을 신은 사용자의 체중이 일측으로 쏠려 발뒤꿈치의 일측단(좌측 또는 우측)이 기울어지면 반대측인 타측단(우측 또는 좌측)의 지탱돌출부재(126)가 이를 지탱하도록 보강하므로 가압 부위의 변형(쏠림)을 최소화하면서 쿠션기능을 배가시킬 수 있다. 더욱이, 지탱돌출부는 발 뒤꿈치 부분에서도 좌우측으로 쏠리지 않는 뒤꿈치(후방 또는 좌후방측 또는 우후방측)로 힘을 받았을 때도 후방과, 좌우의 지탱돌출부재(126)가 반대 방향(전방 또는 우전방측 또는 좌전방측)으로 잡아주게 되므로 뒤꿈치에 힘을 받아도 발 앞쪽이 들리지 않게 된다. 또한, 지탱돌출부는 앞발가락 부분에서도 우측 또는 좌측 또는 발 뒤꿈치와 같이 동일한 효과를 얻는다.In addition, the shock absorber 120 is provided with supporting protrusions at the upper and lower portions, that is, at the boundary points with the outer surface of the sole body 110. The support protrusion minimizes the deformation of the right or left pressed portion by the weight. That is, when the weight of the user wearing shoes is leaned to one side and one side end (left or right) of the heel is tilted, the support protrusion member 126 of the opposite side (right or left) reinforces it to support it, so that the pressure area The cushioning function can be doubled while minimizing deformation (leaking). Moreover, even when the supporting protrusion receives force from the heel (rear or left rear side or right rear side) that does not lean to the left and right even in the heel portion, the rear and left and right supporting protrusion members 126 move in the opposite direction (front or right front side). Or left anterior side), so the front of the foot is not lifted even if the heel is forced. In addition, the supporting protrusion obtains the same effect as the right or left side or the heel in the fore toe portion.
또한, 밑창 본체(110)는 완충부(120)를 기점으로 상하를 구획하게 되며, 상, 하부의 폭이 동일 또는 상이하도록 구비 가능하다.In addition, the sole main body 110 divides the upper and lower portions from the shock absorber 120 as a starting point, and the upper and lower portions may have the same or different widths.
즉, 도 4를 참조하면, 밑창 본체(110) 중 완충부(120)의 상부 폭(a1)이 하부 폭(a2)보다 작게 형성 가능하다. 이 경우, 지면에 닿는 면적이 커서 노인 등과 같은 착용자의 안전성을 도모하게 된다.That is, referring to FIG. 4 , the upper width a1 of the shock absorber 120 of the sole body 110 may be smaller than the lower width a2. In this case, since the area in contact with the ground is large, the safety of wearers such as the elderly is promoted.
이와 다르게, 도면에는 도시하지 않았지만 밑창 본체(110) 중 완충부(120)의 상부 폭이 하부 폭보다 크게 형성하는 경우, 지면에 닿는 면적이 작고 밑창 본체(110)의 하부가 걸리지 않도록 하므로 달리기 용도로 사용 가능하다.Unlike this, although not shown in the drawing, when the upper width of the buffer part 120 is formed to be larger than the lower width of the sole body 110, the area in contact with the ground is small and the lower portion of the sole body 110 is prevented from being caught, so it is used for running. can be used as
더욱이, 밑창 본체(110)는 바닥면 전후방이 라운딩 형성되므로 걷는 과정에서 뒷부분이 닿을 때 지면에 부드럽게 마찰되고, 발을 디뎟을 때 뒷부분이 들리고 밑창 본체의 앞부분에 닿게 되면서 부드럽게 넘어가므로 걸음걸이가 편해지게 된다.Moreover, since the front and rear of the sole body 110 are rounded on the bottom surface, when the rear part touches the ground while walking, the rear part is gently rubbed against the ground. will lose
기둥부(130)는 도 2 및 도 3에 도시된 바와 같이 완충부(120) 중 발날의 바깥쪽 부분이 위치되는 적어도 하나의 지점에 형성된다. 이때, 본 실시예에서는 기둥부(130)가 발날의 바깥쪽 부분 중 앞쪽에 2개 뒤쪽에 1개 이렇게 형성되는 것으로 예시하며, 개수 및 형성 위치는 이에 한정하지 않고 변경 실시가 가능하다.As shown in FIGS. 2 and 3 , the pillar part 130 is formed at at least one point of the buffer part 120 where the outer part of the foot blade is located. At this time, in this embodiment, it is exemplified that the pillar portion 130 is formed with two on the front and one on the rear of the outer part of the foot blade, and the number and formation position are not limited thereto and can be changed.
즉, 기둥부(130)는 밑창 본체(110)의 외면과 동일면 상에 위치되도록 완충부(120)를 채워 형성된다.That is, the pillar part 130 is formed by filling the buffer part 120 so as to be positioned on the same surface as the outer surface of the sole body 110 .
또한, 기둥부(130)는 도 5에 도시된 바와 같이 발날의 바깥쪽 부분과 반대쪽인 발꿈치 안쪽에도 추가적으로 형성 가능하다. 이때, 기둥부(130) 중 발꿈치 안쪽에 구비되는 그것은 1개 형성되는 것으로 예시하며, 개수 및 형성 위치는 이에 한정하지 않고 변경 실시가 가능하다.In addition, as shown in FIG. 5 , the pillar portion 130 may additionally be formed on the inside of the heel opposite to the outer portion of the foot blade. At this time, it is exemplified that one pillar part 130 provided on the inside of the heel is formed, and the number and formation position are not limited thereto and can be changed.
이렇게, 기둥부(130)는 발날의 바깥쪽 부분에 구비되면 뒤뚱거림 방지와 함께 체중 쏠림으로 인한 발이 바깥쪽으로 꺾이지 않게 하면서 장시간 걸을 수 있게 하고, 발뒤꿈치 안쪽에 구비되면 상대적으로 꺾임율이 낮은 발 안쪽으로도 꺾임 현상을 추가적으로 방지하게 된다.In this way, when the pillar part 130 is provided on the outer part of the foot blade, it prevents waddling and prevents the foot from bending outward due to weight inclination, so that the foot can walk for a long time, and when provided on the inside of the heel, the foot with a relatively low bending rate Inward bending is additionally prevented.
한편, 도면에는 도시하지 않았지만 기둥부(130)는 밑창 본체(110)와 다른 재질로 성형할 수 있다. 즉, 완충부(120) 일부를 밑창 본체(110)보다 경질의 재질로 성형하여 체중에 의한 가압 부위의 변형을 최소화할 수 있다. Meanwhile, although not shown in the drawings, the pillar portion 130 may be formed of a material different from that of the sole body 110 . That is, by molding a part of the shock absorbing part 120 with a material harder than the sole body 110, deformation of the pressurized part due to body weight can be minimized.
이외에도 도면에는 도시하지 않았지만, 밑창 본체(110)의 성형시 기둥부(130)가 위치되는 부분에 홈을 형성하고, 경질의 재질로 구비된 기둥부(130)를 홈 내에 삽입 고정이 가능하다. 이때, 기둥부(130)의 대향면과 기둥부(130)가 삽입되는 밑창 본체(110)의 홈 대향면이 요철 결합 가능하다. In addition, although not shown in the drawing, a groove is formed at the part where the pillar part 130 is located when molding the sole body 110, and the pillar part 130 made of a hard material can be inserted and fixed into the groove. At this time, the opposite surface of the pillar part 130 and the groove facing surface of the sole body 110 into which the pillar part 130 is inserted can be concavo-convexly coupled.
또한, 기둥부(130)를 밑창 본체(110)의 홈 내에 삽입할 때 홈의 입구의 가장자리를 따라 중심방향으로 돌출시켜 기둥부(130)의 분리를 방지 가능하다.In addition, when the pillar part 130 is inserted into the groove of the sole body 110, separation of the pillar part 130 can be prevented by protruding toward the center along the edge of the inlet of the groove.
이와 같이, 본 발명에 의한 쿠션기능을 구비한 신발 밑창(100)은 밑창 본체(110)의 외면을 따라 함몰된 완충부(120)가 형성되고, 완충부(120) 중 발날의 바깥쪽 부분 중 앞쪽과 뒤쪽에 기둥부(130)가 형성되면서 선택적으로 발꿈치 안쪽에도 추가적으로 형성 가능하므로 완충부(120)에 의해 충격을 흡수 가능하고 장시간 걸을 수 있으면서 걸음걸이가 빨라지게 하는 효과가 있다.As described above, in the shoe sole 100 having a cushion function according to the present invention, a shock absorber 120 is formed along the outer surface of the sole body 110, and among the shock absorber 120, the outer part of the foot blade is formed. Since the pillar portion 130 is formed on the front and rear sides and can optionally be additionally formed on the inside of the heel, shock can be absorbed by the buffer portion 120, and walking for a long time has the effect of speeding up the gait.
더욱이, 밑창 본체(110)는 바닥면 전후방에 형성된 곡면에 의해 걷는 과정에서 뒷부분이 닿을 때 지면에 부드럽게 마찰되고, 발을 디뎟을 때 뒷부분이 들리고 밑창 본체의 앞부분에 닿게 되면서 부드럽게 넘어가므로 걸음걸이가 편해지게 된다.Furthermore, the sole body 110 is gently rubbed against the ground when the rear part touches the ground in the process of walking due to the curved surfaces formed on the front and rear surfaces of the sole body 110, and the rear part lifts when the foot steps and moves smoothly while touching the front part of the sole body, so the gait is improved. become comfortable
그리고 기둥부(130)는 체중에 의한 가압시 반발력이 형성되도록 하므로 체중 쏠림으로 인한 발이 바깥쪽으로 꺾이지 않게 한다.In addition, since the pillar portion 130 forms a repulsive force when pressurized by the weight, it prevents the foot from bending outward due to weight inclination.
또한, 발뒤꿈치 안쪽에도 기둥부(130)가 형성되므로 혹시 모를 발의 안쪽 방향 꺾임을 방지 가능하다.In addition, since the pillar part 130 is formed on the inside of the heel, it is possible to prevent the inward bending of the foot.
