상기와 같이 구성되어 있는 본 발명의 작용관계를 도 1 내지 도 6을 참고하여 설명하면 다음과 같다.Referring to Figures 1 to 6 the working relationship of the present invention configured as described above is as follows.
본 발명에 의한 신발창(1)이 부착된 신발을 착용하고 보행을 하게 되면, 본 발명을 구성하는 신발창(1)에는 상측부터 신발창본체(2)와, 1차쿠션(4), 그리고 2차쿠션(5)이 차례로 적층되어 3단의 층을 이루며 3단으로 쿠션이 작용하게 된다.When the shoe sole 1 according to the present invention is worn with walking shoes, the sole 1 constituting the present invention has a sole body 2, a primary cushion 4, and a secondary cushion from the upper side. (5) is stacked in order to form a three-tier layer and the cushion acts in three stages.
특히, 보행 중 뒤축에 가장 큰 하중이 작용하는데, 본 발명의 신발창(1)에는 뒤축부분에 3단으로 쿠션작용이 이루어지게 함에 따라 발뒤축에 작용하는 충격을 우수하게 완화시키게 된다.In particular, the largest load acts on the heel during walking, the shoe sole 1 of the present invention is excellent cushioning of the impact acting on the heel of the foot as the cushion acts in three stages in the heel.
상기 신발창본체(2)는 1,2차쿠션(4,5) 보다 경도(58도 내외)가 높아서 발바닥을 충분히 지지해주게 되어 발바닥이 내측이나 또는 외측으로 급격히 주저앉지 않게 한다.The sole body 2 has a higher hardness (about 58 degrees) than the primary and secondary cushions 4 and 5 to sufficiently support the soles of the soles so that the soles do not suddenly fall to the inside or the outside.
위에서 칭한 경도 58도는 너무 단단하지도 않고 너무 무르지도 않은 상태로서 엄지로 강하게 눌렀을 때, 쿠션감을 느낄 정도로 쿠션을 지니고 있는 상태로서 발바닥을 지지함과 아울러 발바닥에 딱딱한 느낌을 주지 않고 약간은 부드러움을 느낄 수 있을 정도이다.The hardness of 58 degrees is not too hard and not too soft. When pressed strongly with your thumb, it has a cushion enough to feel a cushion, supporting the soles of the feet and not feeling hard on the soles. It is enough.
위와 같이 신발창본체(2)에서 발바닥을 지지하는 상황에서 그 하측에는 신발창본체(2) 보다 절반정도로 경도가 낮은 1차쿠션(4)이 위치하고 있어서 이 1차쿠션(4)에서 푹신한 느낌으로 압축되면서 2차로 쿠션이 작용하게 되며, 그 하측에 설치된 2차쿠션(5)은 1차쿠션(4) 보다는 경도가 높고 신발창본체(2) 보다는 경도나 낮아서 1차쿠션(4)이 최대로 압축되는 것을 그 하측에서 받쳐주면서 3차로 쿠션작용하게 된다.In the situation where the sole body (2) supports the sole as above, the primary cushion (4), which is about half the hardness of the sole body (2), is located at the lower side, and the primary cushion (4) is compressed with a soft feeling. The cushion acts as a secondary, and the secondary cushion (5) installed on the lower side is higher than the primary cushion (4) and the hardness is lower than the sole body (2), so that the primary cushion (4) is compressed to the maximum. Supporting from the lower side will be cushioned third.
따라서, 본 발명에 의한 신발창(1)은 뒤축 부분에서 3단계로 완충작용을 하여 편안한 착용감을 제공하게 되는 것이다.Therefore, the sole 1 according to the present invention is to provide a comfortable fit by buffering in three steps in the heel portion.
그리고, 상기와 같이 뒤축부분에서 완충작용을 할 때, 가장 경도나 낮아 무른 1차쿠션(4)이 신발창본체(2)와 2차쿠션(5) 사이에 개재되어 있으면서, 1차쿠션(4)의 전후방측에서는 2차쿠션홈부(3b) 부분이 1차쿠션(4) 보다 경도가 높은 신발창본체(2)와 2차쿠션(5)의 전후방이 받치고 있어서, 2차쿠션홈부(3b) 부분이 크게 압축되지 않고 1차쿠션(4)이 설치된 부분에서 상하로 신축의 폭이 큼에 따라 1차쿠션(4)이 설치된 부분에서 우수한 쿠션이 작용하게 된다.And, when the cushioning action in the rear axle portion as described above, the primary cushion (4) while the first and second cushion (4) is the most soft and soft, interposed between the sole body (2) and the secondary cushion (5) The front and rear sides of the secondary cushion groove portion 3b are supported by the front and rear portions of the sole body 2 and the secondary cushion 5 having higher hardness than the primary cushion 4, so that the portion of the secondary cushion groove portion 3b is large. As the width of the expansion and contraction is increased up and down in the portion where the primary cushion 4 is installed without compression, the excellent cushion acts in the portion where the primary cushion 4 is installed.
이러한, 신발창(1)에서 2차쿠션(5)과 신발창본체(2)의 저면을 질긴 소재로 형성된 논슬립창(8)이 부착 설치되어서 논슬립창(8) 보다 질기지 않은 신발창본체(2)와 2차쿠션(5)의 마모를 예방함과 아울러, 신발창(1)의 저면부분에서 신발창본체(2)와 2차쿠션(5)이 연결되는 부분이 질긴 소재로 된 논슬립창(8)이 커버함에 따라 2차쿠션(5)과, 2차쿠션(5)이 연결된 부분이 분리되지 않게 하는 기능을 함께 하게 되는 것이다.In the shoe sole 1, the non-slip window 8 formed of a material having a chewy bottom surface of the secondary cushion 5 and the sole body 2 is attached to the sole body 2 which is less durable than the non-slip window 8. In addition to preventing wear of the secondary cushion (5), the non-slip window (8) made of a tough material is covered in the bottom portion of the sole (1) where the sole body (2) and the secondary cushion (5) are connected. As the secondary cushion (5), and the secondary cushion (5) connected to the function that will not be separated.
본 발명에 의한 신발창(1)이 부착 설치된 신발을 착용한 상태로 보행을 하는 과정에서 제일 먼저 뒤축이 지면을 디딜 때, 위에서의 설명에서와 같이 신발창본체(2) 및 1,2차쿠션(4,5)에 의해 3단으로 쿠션작용을 함과 동시에 상기와 같이 발뒤축이 후방생크(10)의 후방측을 누르게 된다.When the heel treads the ground first in the process of walking in the state of wearing a shoe with an attached shoe sole 1 according to the present invention, the sole body 2 and the primary and secondary cushions 4 as described above. By the step 5, cushioning in three stages at the same time as the heel of the foot presses the rear side of the rear shank (10).
상기와 같이 발뒤축이 후방생크(10)의 후방측을 강하게 디딜 때, 도 2 및 도 3에서 보는 바와 같이 후방생크(10)의 후방측이 디뎌지면서 그 전방측은 허공에 뜬 상태가 되는데, 생크는 전후방생크(9,10)로 분리 형성된 상태에서 전후방생크(9,10)가 마주 대하며 끼워진 끼움부(15)가 순간적으로 솟아오르게 된다.As described above, when the heel of the foot treads the rear side of the rear shank 10 strongly, the rear side of the rear shank 10 treads as shown in FIGS. 2 and 3, and the front side is in the air. In the state formed separately from the front and rear shanks 9 and 10, the front and rear shanks 9 and 10 face each other, and the fitted portion 15 is immediately raised.
이렇게 전후방생크(9,10)가 마주대하는 부분이 순간적으로 솟아오른 상태에서 뒤이어 곧바로 발바닥의 중앙부분이 지면을 접촉하게 되는데, 이때 전후방생크(9,10)의 솟아오른 끼움부(15)가 발바닥의 중간부분에 밟히게 된다.In this way, the front and rear shank (9, 10) facing each other immediately rises in a state where the center portion of the sole immediately contacted the ground, at this time the raised portion (15) of the front and rear shank (9, 10) is the sole Stepped in the middle of the.
이때, 전후방생크(9,10)의 끼움부(15)에 형성된 핑거부(13)에는 돌기부(16)가 돌출되게 형성되어서 그 돌기부(16) 들이 발바닥에 밟히면서 발바닥을 자극하게 되는데, 발바닥의 중앙부분, 특히 족궁(아치부) 부위에는 다수개의 경혈점이 분포되어서 그 다수개의 경혈점들이 돌기부(16)에 자극되면서 마사지 효과를 볼 수 있게 되는 것이다.At this time, the finger portion 13 formed on the fitting portion 15 of the front and rear shanks 9 and 10 is formed so that the protrusions 16 protrude so that the protrusions 16 step on the soles of the feet to stimulate the soles of the soles. The central part, especially the foot arch (arch part) is a plurality of acupuncture points are distributed so that the plurality of acupuncture points are stimulated by the protrusions 16 will be able to see the massage effect.
이와 같이 상측으로 솟아오른 부분이 발바닥의 중앙부에 밟히면서 전후방생크(9,10)가 마주 대하는 부분이 하측으로 내려가고, 뒤이어 발바닥의 전방하측이 지면을 밟을 때에도 발바닥에 밟힌 부분은 내려가고 밟히지 않은 부분은 후방생크(10) 보다는 그 상하로 오르내리는 높이가 낮지만 전방생크(9)도 앞쪽은 내려가고 뒤쪽은 올라가게 된다.In this way, the part that rises upward is stepped on the center of the sole, and the part facing the front and rear shanks (9,10) goes down, and when the front and the bottom of the sole step on the ground, the part stepped on the sole goes down and is stepped on. The lower part is lower than the rear shank 10, the height is lowered up and down, but the front shank (9) also goes down the front and the rear is raised.
위와 같이 전후방생크(9,10)가 발바닥에 밟히는 부분이 내려가고 밟히지 않은 부분이 올라가는 것은 전후방생크(9,10)를 호형으로 형성하면서, 이들 전후방생크(9,10)가 마주 대하는 부분이 양측 손가락을 마주 끼운 상태와 같은 상태에서 쿠션을 지닌 신발창본체(2)의 내부에 매설된 상태임에 따라 전후방생크(9,10)이 올라가고 내려가는 동작을 반복하게 된다.As described above, the portions where the front and rear shanks 9 and 10 step on the sole are lowered and the parts not stepped on form the front and rear shanks 9 and 10 as arcs, while the front and rear shanks 9 and 10 face each other. The front and rear shanks 9 and 10 are repeatedly moved up and down according to the state of being embedded in the sole body 2 having a cushion in a state where both fingers are faced with each other.
따라서, 보행자의 발바닥은 위와 같이 상하로 움직이는 끼움부(15)의 돌기부를 반복적으로 밟으면서 발바닥에 대한 마사지 효과를 볼 수 있게 되는 것이다.Therefore, the sole of the pedestrian is able to see the massage effect on the sole while repeatedly stepping on the protrusion of the fitting portion 15 moving up and down as above.
도 6의 경우에 전후방생크(9,10)의 끼움부(15)가 위치하는 부분에 신발창본체(2)를 형성하는 소재가 채워지지 않고 중공 상태인 공간부(7)가 형성되어서 상기와 같이 전후방생크(9,10)가 도 3에서 보는 바와 같이 솟아오름과 내려감을 반복할 때, 그 전후방생크(9,10) 부분이 더욱더 잘 구부려지게 되고, 발바닥에 더욱 더 근 자극을 줄 수 있게 되는 것이다.In the case of FIG. 6, the hollow portion 7 is not formed and the hollow portion 7 is formed in the portion where the fitting portions 15 of the front and rear shanks 9 and 10 are located, and is hollow as described above. When the front and rear shanks 9 and 10 are repeatedly raised and lowered as shown in FIG. 3, the front and rear shanks 9 and 10 are bent more and more, and the foot soles can be further stimulated. will be.
