Description
본 발명은 신발용 바닥부에 관한 것으로, 더욱 구체적으로는 고강도 내마모성 엘라스토머를 사용하고, 새로운 바닥부 구조를 적용하여 쿠션용 발포 입자들이 벌집 구조를 형성하는 기능성 신발용 바닥부 및 이를 이용한 신발에 관한 것이다.The present invention relates to soles for shoes, and more specifically, to soles for functional shoes in which foam particles for cushioning form a honeycomb structure by using high-strength, wear-resistant elastomer and applying a new sole structure, and to shoes using the same. will be.
일반적으로 신발은 인체의 발부위를 보호하기 위하여 착용하는 것으로서 매우 다양한 형태와 종류로 제작되어 시판되고 있으나, 통상적으로는 발등과 발목 부위을 덮어서 보호하는 갑피(甲皮)와, 발바닥을 보호하면서 지면과의 마찰력을 높여 보행성을 향상시키도록 하는 동시에, 보행시 발바닥에 가해지는 충격을 완화시키도록 하는 신발밑창으로 구성되고 있다.In general, shoes are worn to protect the feet of the human body and are manufactured and sold in a wide variety of shapes and types. However, they usually consist of an upper that covers and protects the instep and ankle area, and an upper that protects the sole of the foot and protects the ground and the ground. It consists of a shoe sole that improves walking ability by increasing friction and at the same time relieves the shock applied to the sole of the foot when walking.
상기와 같은 통상적인 신발의 경우 보행시 지면으로부터 발바닥으로 전해지는 충격을 흡수할 수 있도록, 신발의 내측 바닥면에 깔창을 깔거나 신발밑창과 뒤축 부분을 완충력이 우수한 고무 및 발포 스폰지 재질로 제작하거나, 또는 에어백(Air bag)이나 스프링 등의 탄성복원체를 신발밑창에 내장시키도록 한 것이 알려져 있다.In the case of conventional shoes as described above, in order to absorb the shock transmitted from the ground to the sole of the foot when walking, an insole is placed on the inner sole of the shoe, or the sole and heel are made of rubber or foam sponge material with excellent cushioning power. It is known that elastic restorers such as air bags or springs are built into shoe soles.
상기와 같이 고무나 발포 스폰지 재질로 신발밑창을 제조하거나 또는 에어백이나 스프링 등의 탄성복원체를 신발밑창에 내장시킨 경우에는 단순한 충격 흡수의 기능만을 수행할 수 있을 뿐이며, 보행자의 발뒤꿈치로부터 발가락에 이르기까지 개략 원호 형상을 가지면서 지면과 접촉하게 되는 보행경로를 기준으로 할 경우, 종래의 일반적인 신발밑창은 자연적이고 능률적인 보행을 수행토록 하는 측면에 거의 기여하지 못하는 문제점이 있었다.As described above, when shoe soles are made of rubber or foam sponge, or when elastic restorers such as airbags or springs are built into shoe soles, they can only perform a simple shock absorption function, and can only perform the function of simple shock absorption, and can affect the pedestrian's heels and toes. When based on a walking path that has a roughly circular shape and is in contact with the ground, conventional shoe soles have a problem in that they hardly contribute to the aspect of performing natural and efficient walking.
또한 종래 기술의 모든 발포 신발 밑창에는 문제점이 있는데, 예를 들어 EVA, PU, 아디다스 팝콘, PU 발포 팝콘 등은 착용시 물을 흡수하고 냄새가 나며, 공공장소(병원 등) 출입시 더러운 물을 빨아 들여 세균 등을 집으로 가져오게 된다.In addition, all foam shoe soles in the prior art have problems. For example, EVA, PU, Adidas popcorn, PU foam popcorn, etc. absorb water and smell when worn, and suck dirty water when entering public places (hospitals, etc.). You bring germs and germs into your home.
또한 밑창의 경우 내부를 청소할 수 없으며, 연결된 통풍구 등의 전도 효과로 인해 겨울에는 땅에서 추위를, 여름에는 땅에서 열을 흡수하는 문제점이 있다.Additionally, the inside of the sole cannot be cleaned, and due to the conduction effect of connected vents, there is a problem of absorbing cold from the ground in winter and heat from the ground in summer.
관련된 종래기술로 등록특허 10-1644454호(충격흡수, 이물질 낌 방지 및 미끄럼방지 구조를 가지는 신발밑창)는,As a related prior art, registered patent No. 10-1644454 (shoe sole with shock absorption, foreign matter prevention, and anti-slip structure),
"밑판과, 상기 밑판에 다수 개의 조각구가 돌출 형성된 신발밑창에 있어서, 상기 조각구는, 내측에서 외측으로 절개된 복수 개의 분할홈에 의해 구획된 단위조각구가 형성되어 지면과 맞닿아 충격을 흡수하고, 상기 조각구 각각 사이에는 연결구로 연결되어 상기 단위조각구의 충격하중을 분산하는 것을 특징으로 하고, 조각구 사이의 간격을 조각구 높이보다 동일 또는 그 이상으로 하여 이물질 낌 현상을 방지하여 조각구 간격을 좁혀 밀착력, 충격흡수 및 미끄럼방지 기능을 향상시킨 신발밑창"을 제시한바 있다."In a shoe sole having a sole plate and a plurality of sculpture holes protruding from the sole plate, the sculpture holes are formed as unit sculpture spheres divided by a plurality of split grooves cut from the inside to the outside, and come into contact with the ground to absorb shock. And, each of the sculpture spheres is connected by a connector to distribute the impact load of the unit sculpture sphere, and the spacing between the sculpture spheres is made equal to or greater than the height of the sculpture spheres to prevent the phenomenon of foreign matter sticking to the sculpture sphere. A shoe sole that narrows the gap and improves adhesion, shock absorption, and anti-slip functions has been proposed.
상기한 종래기술 및 선행기술은 밑창의 쿠션부가 발포입자로 되어 있지만 이러한 발포입자 쿠션부에 통풍구가 형성되어 있어, 착용시 물을 흡수하고 냄새가 나며, 공공장소(병원 등) 출입시 더러운 물을 빨아 들여 세균 등을 집으로 가져오게 되는 문제점 및 연결된 통풍구에 따른 전도 효과로 인해 겨울에는 땅에서 추위를, 여름에는 땅에서 열을 흡수하는 문제점을 있는바,In the above-described prior art and prior art, the cushion part of the sole is made of foam particles, but vents are formed in the foam particle cushion part, so it absorbs water and generates odor when worn, and dirty water is discharged when entering and exiting public places (hospitals, etc.). There is the problem of sucking in germs and bringing them into the house, and the problem of absorbing cold from the ground in winter and heat from the ground in summer due to the conduction effect of connected vents.
본 발명은 상기한 문제점을 해결하는 기능성 신발용 바닥부 및 이를 이용한 신발을 제공하고자 한다.The present invention seeks to provide a functional shoe sole that solves the above problems and a shoe using the same.
또한 본 발명은 발포된 완충입자부가 닳아도 오염된 물과 세균은 표면에 입자층만 남게되어 깊은 내부로 빨려 들어 가지 않기 때문에 자연 건조 및 살균이 용이하게 되며, 또한, 완충접합부가 투명하여 직사광선으로 살균하는 기능도 수행할 수 있는 기능성 신발용 바닥부 및 이를 이용한 신발을 제공하고자 한다.In addition, the present invention facilitates natural drying and sterilization because even when the foamed buffer particle part wears out, only the particle layer remains on the surface and the contaminated water and bacteria are not sucked deep into the interior. In addition, the buffer joint is transparent, so it can be sterilized by direct sunlight. The goal is to provide functional shoe soles that can also perform the following functions and shoes using them.

또한 본 발명은 상기한 완충입자부(221)의 완충입자(221-1)는 폴리우레탄 재질로 된 것이고,In addition, in the present invention, the buffer particles 221-1 of the buffer particle unit 221 are made of polyurethane material,

도 3에서 보는 바처럼, 완충부(220)는 상기한 바닥부(200)의 내부에 안치되어 형성되는 구조로 되어 있다.As shown in FIG. 3, the buffer portion 220 is structured to be placed inside the bottom portion 200 described above.
또한 상기한 완충부(220)는 바닥본체부(210)와 결합하여 형성될 수 있으며 완충부(220)의 일부는 바닥에 직접 접촉할 수 있는 구조로 형성될 수 있다.Additionally, the buffer unit 220 may be formed in combination with the floor body unit 210, and a portion of the buffer unit 220 may be formed in a structure that can directly contact the floor.
본 발명의 이와 같은 완충부는 투명하고 통풍구가 연결되어 있지 않고 접착제를 사용하지 않는 특징을 갖는다,This buffer part of the present invention has the characteristics of being transparent, not connected to ventilation holes, and using no adhesive.
또한 본 발명은 완충입자부(221)와 완충접합부(222)가 결합하여 일체로 형성되어 발포 입자 사이의 기공을 밀봉하고 채우게 되며 발포 입자 사이에 연결된 통풍구가 없기 때문에 종래 기술의 발포 입자를 사용하는 경우의 문제점을 해결하게 된다.In addition, the present invention is formed by combining the cushioning particle portion 221 and the cushioning joint portion 222 to seal and fill the pores between the foam particles. Since there is no ventilation hole connected between the foam particles, it is possible to use foam particles of the prior art. This solves the problem in the case.
즉, 본 발명은 종래기술의 쿠션용 밑창을 가진 신발의 경우 쿠션부가 발포입자로 되고 이러한 발포입자 쿠션부에 통풍구가 형성되어 있어 신발 착용시 물을 흡수하고 냄새가 나며, 공공장소(병원 등) 출입시 더러운 물을 빨아 들여 세균 등을 집으로 가져오게 되는 문제점이 있고, 또한 종래기술의 경우 쿠션부의 통풍구에 의한 전도 효과로 인해 겨울에는 땅에서 추위를, 여름에는 땅에서 열을 흡수하는 문제점을 있는 데 이를 완전히 해결하게 된다.That is, in the present invention, in the case of shoes with a conventional cushion sole, the cushion part is made of foam particles and a ventilation hole is formed in the foam particle cushion part, so that water is absorbed and odor is generated when the shoe is worn, and it is used in public places (hospitals, etc.) There is a problem of sucking in dirty water and bringing germs into the house when entering and exiting, and in the case of the prior art, there is a problem of absorbing cold from the ground in winter and heat from the ground in summer due to the conduction effect caused by the vents in the cushion part. This will be completely resolved.
또한, 발포된 완충입자부(221)가 닳아도 오염 된 물과 세균은 표면에 입자층 만 남게되어 깊은 내부로 빨려 들어 가지 않기 때문에 자연 건조 및 살균이 용이하게 되며, 또한, 엘라스토머를 주재료로 한 완충접합부(222)는 투명하여 직사광선으로 직접 바닥부를 살균하는 기능도 수행하게 된다.In addition, even if the foamed cushioning particle part 221 wears out, only the particle layer remains on the surface and the contaminated water and bacteria are not sucked into the deep interior, making natural drying and sterilization easy. In addition, the cushioning material made of elastomer is easy. The joint 222 is transparent, so it also performs the function of sterilizing the bottom directly with direct sunlight.
