Description

완충구가 내입된 구두굽{Heel of shoes with inner buffer}Heel of shoes with inner buffer}

본 발명은 보행 시 뒷굽에 미치는 충격 하중을 완화시키기 위하여 구두 뒷굽에 탄력성 재질의 완충구를 내입한 보다 개선된 구두굽에 관한 것이다.The present invention relates to a more improved shoe heel incorporating a cushioning material of the elastic material in the shoe heel to mitigate the impact load on the heel when walking.

종래의 신발에도 신체 하중이 많이 미치는 뒷굽 부위에 스프링을 내장하여 완충기능을 부여한 신발이 제안된 바 있으나, 이는 구조가 비교적 복잡하여 비경제적이고, 장기 착용 중 스프링부가 변형되어 완충기능이 장기간 지속되지 못하는 결점이 있었다.
본 발명은 이러한 스프링 내장식 완충구두의 구성과 달리 구두 뒷굽 부위에 신축 탄력이 양호한 완충구를 수납하여 하방에 접설한 작동핀이 상하 승강 작동되면서 완충기능을 원활히 수행할 수 있도록 한 것이다.Conventional shoes have been proposed to impart cushioning function by embedding springs in the heel of the body, which has a large body load. However, this is a relatively complicated structure, which is uneconomical and prevents the cushioning function from being prolonged for a long time due to deformation of the spring part. There was a flaw.
The present invention, unlike the configuration of the spring-incorporated cushioning shoes to accommodate the cushioning elastic good elastic elasticity in the heel of the shoe is to enable the operation function to be installed in the lower and lower lifting operation to smoothly perform the cushioning function.

본 발명은 구두 뒷굽 부위를 고정상태가 아닌 상하 승강 작동식으로 구성한데 특징이 있으며, 지면에 착지되는 작동핀이 스프링에 의한 방식이 아니라 탄력성 합성수지로 구성되는 완충구에 의해 뒷굽이 착지될 시는 뒷굽 내부로 삽입되고, 착지가 해제될 시는 상기 완충구의 탄력에 의해 밖으로 진출하여 신체 하중이 뒷굽에 가해질 때마다 일정한 완충력을 발휘하게 한 것이다.The present invention is characterized in that the heel portion of the shoe is not fixed, but configured to move up and down, when the heel is landed by the cushioning mechanism consisting of a flexible synthetic resin rather than a spring-based operating pin When inserted into the heel and landing is released, the elasticity of the buffer opening to the outside to exert a certain buffering force whenever the body load is applied to the heel.

본 발명의 구성이 갖는 특징은 구두 뒷굽의 중간부에 수납실을 형성하여 그 내부에 신축 탄성이 극히 양호한 완충구와 승강 작동핀을 상하로 내장하여 보행 시 작동핀이 지면에 착지될 시에는 신체 하중에 의해 상기 내장된 완충구가 내측으로 압축되어 작동핀이 뒷굽 본체 속에 진입하면서 완충기능을 발휘하고, 신체 하중이 해소되면 완충구의 복원탄력에 의해 작동핀이 밖으로 진출하도록 구성한 것이다.Features of the configuration of the present invention is to form a storage compartment in the middle of the heel of the shoe, the elastic elasticity is excellent in the elastic body therein and the lifting operation pin built up and down the body load when the operating pin is landing on the ground when walking By the built-in shock absorber is compressed into the inside to act as a working pin enters the heel main body to exhibit a cushioning function, when the body load is released by the restoring elasticity of the shock absorber is configured to go out.

본 발명은 구두 뒷굽에 실리콘 등 탄력성 합성수지제로 된 완충구를 피스톤식으로 승강 작동되는 작동핀과 접합 내장하여 신발 뒷축에 완충기능을 부여함으로써 보행 시 신체에 전가되는 충격부하를 완화하여 신발의 착용감을 향상시키고, 보행에 따른 피로감을 경감할 수 있어 구두의 상품 가치를 크게 향상시킬 수 있는 효과를 가진다.The present invention provides a cushioning function made of elastic synthetic resin such as silicone in the heel of the shoe and the operation pin for lifting and lowering the piston to provide a cushioning function to the heel of the shoe, thereby relieving the impact load transmitted to the body when walking, thereby making the shoe fit. It can improve and reduce the fatigue caused by walking, which has the effect of greatly improving the product value of shoes.

도 1은 본 발명의 단면도이고, 도 2는 도 1의 구성 중 내부에 수용하는 완충구의 사시도이며, 도 3은 본 발명의 장치가 설치된 구두의 측면도이며, 도 5는 본 발명의 요부를 발췌한 분리 사시도이다.
본 발명의 적용대상은 주로 여성용 신발(뒷굽이 높은 하이힐 계통)과 뒷굽이 높은 남성용 구두에 적용한다.
본 발명은 뒷굽본체(1) 내부에 상측 개구부(3)와 하측 개구부(4)에 의해 상하로 관통되는 수납실(2)을 형성하고, 상기 수납실(2)의 하측에는 단턱부(11)를 두어 이 단턱부(11)에 걸리도록 상부에 헤드(5a)가 일체로 형성된 원통형의 작동핀(5)을 상측 개구부(3)측으로부터 끼워 넣어 하측 개구부(4)로 하향 돌출되도록 구성한다.
상기 작동핀(5)은 금속제 및 경질 합성수지제 등 견고한 재질로 형성하며, 바람직하기로는 하측 접지부(接地部)측에 마모방지팁(5b)을 부착시킨다.
상기 작동핀(5)의 상부측 수납실(2)에는 탄력성 재질의 완충구(6)를 내입하되, 완충구(6)는 고밀도 실리콘, 합성고무, 천연고무 등 양호한 탄력을 갖는 재질을 선택하며, 상기 완충구(6)의 내부에는 하부가 개방되고 상부가 막힌 상태의 공실(6a)을 형성하여 일정한 공간을 둔다. 이 공간은 완충구(6)가 하중에 의해 압축될 시 완충구(6)의 높이가 낮아지도록 수축량을 흡수하기 위한 것이며, 이러한 압축 시 공실(6a) 내부에서 하부로 밀려나오는 공기는 수납실(2) 측면의 배기공(7)으로 배출되도록 구성한다.
상기 완충구(6)의 상측 개구부(3)에는 측벽에 나사부(3a)를 형성하여 상기 완충구(6)가 상부로 이탈하지 못하도록 고정볼트(8)를 나사 결합한다.
도면 중 미 설명부호 8a는 상기 고정볼트(8)를 돌리는 요입홈이다.
이상과 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.
본 발명의 완충장치가 구비된 신발을 착용하고 보행을 하게 되면 뒷굽본체(1)의 작동핀(5)이 지면에 착지될 시 작동핀(5) 자체는 경질이고 완충구(6)는 일정 탄성력을 갖는 연질이므로 신체 하중에 의해 완충구(6)가 뒷굽본체(1)에 나사 결합된 고정볼트(8)의 지지압력을 받아 도 4와 같이 압축되므로 그 높이가 낮아진다.
이때 공실(6a)은 완충구(6)의 수축되는 부피를 흡수하는 여유 공간의 기능을 하므로 자연히 공실(6a)의 부피는 작아지고, 공실(6a) 내부의 공기는 하부로 밀려나 수납실(2) 측벽의 틈새를 통해 배기공(7) 밖으로 배출되어 완충구(6)의 수축 기능을 원활하게 한다.
이와 같이 완충구(6)가 수축되어 상하 높이가 낮아지는 만큼 작동핀(5)은 수납실(2) 속으로 삽입되어 들어가게 되고, 뒷굽이 지면으로부터 떨어져 신체 하중이 가해지지 않을 시에는 상기 완충구(6)가 양호한 복원탄성을 발휘하여 작동핀(5)의 헤드(5a)를 밀게 되며, 헤드(5a)가 단턱부(11)에 걸리면서 완충구(6) 자체는 도 1과 같은 원래의 상태로 복귀된다.
상기 완충구(6)의 복귀 시 공실(6a)도 원래의 형태로 복귀하므로 이때는 공실(6a)측에 진공압이 미쳐서 배기공(7)으로부터 공기가 수납실(2) 내부를 통해 공실(6a)에 보충됨으로써 완충구(6)의 복귀기능이 그만큼 신속하게 이루어진다.
본 발명은 상기와 같은 완충구(6)의 양호한 수축 및 팽창 작용에 따라 작동핀(5)의 하측 개구부(4)를 통해 일정한 높이로 출몰(出沒)하게 되는바, 보행 시 이러한 구두 뒷굽의 높낮이 변화는 다음과 같은 기능상의 장점을 가진다.
① 구두를 신고 보행 시 뒷굽이 지면에 닿으면 신체 하중에 의해 작동핀(5)이 수납실(2) 내부로 밀려들어가면서 내부의 완충구(6)를 압축하게 되므로 착지 충격이 신체에 바로 전달되지 않고, 완충구(6)에 가하여져 상당량의 완충력을 발휘하므로 보행의 피로감을 크게 경감시킨다.
② 뒷굽의 착지 감촉이 종래와 같이 딱딱하지 않으므로 보행 시 부드러운 완충 탄력을 늘 감지하게 되어 보행 감각이 사뿐사뿐할 정도로 늘 구두의 착용감이 경쾌하고 부드러운 것이다.
③ 착지 시 신체에 가해지는 충격 압력이 상당량 감소하므로 관절에 무리한 하중이 전달되지 않아 관절보호에 효과가 크고, 따라서 관절이 약하거나 퇴행성 관절질환을 갖는 사람들의 건강 신발로도 크게 기여할 수 있다.
④ 내부의 완충구(6)를 적정한 탄력을 갖는 고밀도 합성수지제로 제조, 형성하므로 완충기능이 극히 양호하고, 내구성을 보장할 수 있으며, 구조적으로도 간단하고 안정성이 있어 고장 발생의 우려가 적다.Figure 1 is a cross-sectional view of the present invention, Figure 2 is a perspective view of the cushioning device accommodated inside of the configuration of Figure 1, Figure 3 is a side view of the shoe is installed the device of the present invention, Figure 5 is an extract of the main portion of the present invention Isolated perspective view.
The subject of the present invention is mainly applied to women's shoes (high heels) and high heels men's shoes.
The present invention forms a storage chamber 2 penetrating up and down by the upper opening portion 3 and the lower opening portion 4 in the heel body 1, and the step portion 11 below the storage chamber 2. In such a way, the cylindrical actuating pin 5 having the head 5a integrally formed on the upper end portion 11 so as to be caught by the upper end portion 11 is inserted from the upper opening 3 side, and configured to protrude downward to the lower opening 4.
The operation pin 5 is formed of a rigid material such as metal and hard synthetic resin, and preferably attaches a wear preventing tip 5b to the lower ground portion.
In the upper side storage chamber (2) of the operating pin (5) is inserted into the buffer opening 6 of the elastic material, the buffer hole 6 selects a material having good elasticity, such as high-density silicone, synthetic rubber, natural rubber The inside of the buffer port 6 forms a vacant space 6a in which the lower part is opened and the upper part is blocked, thereby leaving a constant space. This space is for absorbing the amount of shrinkage so that the height of the buffer opening 6 is lowered when the buffer opening 6 is compressed by a load, the air pushed out from the inside of the empty space (6a) during the compression is a storage compartment ( 2) It is configured to be discharged to the exhaust hole (7) of the side.
The upper opening 3 of the buffer opening 6 forms a screw portion 3a on the side wall to screw the fixing bolt 8 to prevent the buffer opening 6 from escaping upward.
Unexplained reference numeral 8a in the drawing is a recess groove for turning the fixing bolt (8).
Referring to the effects of the present invention configured as described above are as follows.
When walking and wearing a shoe equipped with a shock absorber of the present invention, when the actuating pin 5 of the heel body 1 lands on the ground, the actuating pin 5 itself is hard and the cushioning opening 6 has a constant elastic force. Since the soft body having a pressure receiving the support pressure of the fixing bolt (8) screwed to the heel main body 1 by the body load is compressed as shown in Figure 4 because the height is lowered.
At this time, the vacancy 6a functions as a free space that absorbs the contracted volume of the buffer port 6, so that the volume of the vacancy 6a naturally decreases, and the air inside the vacancy 6a is pushed downward to accommodate the storage chamber 2 ) It is discharged out of the exhaust hole 7 through the gap of the side wall to facilitate the contracting function of the buffer port 6.
As the shock absorber 6 is contracted and the vertical height is lowered, the actuating pin 5 is inserted into the storage compartment 2, and when the heel is separated from the ground, the shock absorber is not applied. (6) exerts good restoring elasticity to push the head (5a) of the actuating pin (5), the head (5a) is caught in the stepped portion 11, the buffer port 6 itself in the original state as shown in FIG. Return to.
When the buffer port 6 is returned, the vacancy 6a also returns to its original shape. At this time, the vacuum pressure is exerted on the vacancy 6a side so that air from the exhaust hole 7 passes through the interior of the storage chamber 2 6a. ), The return function of the shock absorbing port 6 is made so fast.
According to the present invention, according to the good contraction and expansion action of the shock absorber 6, it is projected to a certain height through the lower opening 4 of the operation pin 5, and the height of the heel of the shoe when walking Change has the following functional advantages.
① If the heel touches the ground while walking with shoes, the working pin (5) is pushed into the storage compartment (2) by the body load, compressing the internal shock absorber (6). In addition, since it is applied to the buffer opening 6 and exhibits a considerable amount of buffering force, the fatigue of walking is greatly reduced.
② Since the landing texture of the heel is not as hard as before, the soft cushioning elasticity is always detected when walking, and the feeling of wearing is light and soft all the time.
③ The impact pressure on the body is greatly reduced when landing, so it is not effective to transfer the load to the joint, so it is effective in protecting the joint. Therefore, it can contribute greatly to the health shoes of people with weak joints or degenerative joint diseases.
④ The internal buffer port 6 is manufactured and formed of high-density synthetic resin with proper elasticity, so the buffer function is extremely good, durability can be guaranteed, and structurally simple and stable.
