Abstract

본 고안은 신발용 솔(sole)의 완충장치(cushion system)에 관한 것으로서, 더욱 상세히는 제한된 치수를 갖는 아웃솔(outsole)과 미드솔(midsole)에 최대한의 완충효과를 제공코자 하는 것이다.The present invention relates to a cushioning system of a shoe sole, and more particularly, to provide the maximum cushioning effect to an outsole and a midsole having limited dimensions.

즉 아웃솔(1)과 미드솔(2)의 연접면부에 상호 대칭형의 요입실(3, 4)을 형성하고, 양자를 일체로 접착구성함으로서 폐쇄형으로 이루어지는 에어챔버(5)가 보행시 신축되면서 완충역할을 극대화할 수 있도록 하였으며, 특히 제한된 아웃솔(1)과 미드솔(2)의 치수내에서 큰 체적의 에어챔버(5)를 형성함으로서 종래의 에어챔버를 가진 솔에 비하여 월등한 완충기능을 제공받을 수 있고, 미드솔(2)의 요입실(4)면부에는 TPU시트지(6)를 삽입하여 미드솔(2) 성형시 동시 접착되도록 하므로서 TPU시트지(6)는 요입실(3, 4)의 형성으로 인한 솔 전체의 뒤틀림이나 중심이탈, 내구성 저하 등과 같은 문제를 해결해 줌으로서 제품의 내구성 역시 배가할 수 있도록 한 것이다.That is, by forming mutually symmetric indentation chambers 3 and 4 at the joint surfaces of the outsole 1 and the midsole 2, and bonding them together integrally, the closed air chamber 5 expands and contracts while walking. In order to maximize the role, especially the large volume of the air chamber (5) within the dimensions of the limited outsole (1) and the midsole (2) to provide a superior cushioning function compared to the sole having a conventional air chamber The TPU sheet paper 6 is formed by the formation of the indenting chambers 3 and 4 by inserting the TPU sheet paper 6 into the indentation chamber 4 surface portion of the midsole 2 so as to be simultaneously bonded when the midsole 2 is formed. It solves problems such as twisting of the sole, deviation from the center, and deterioration of durability, thereby increasing the durability of the product.

Description

신발용 솔의 완충장치Buffer of shoe brush

본 고안은 신발용 솔(SOLE)의 완충장치에 관한 것으로서, 더욱 상세히는 신발용 아웃솔과 미드솔 상간에 적용되는 완충장치를 제공코자 하는 것이다.The present invention relates to a shock absorber of a shoe sole (SOLE), and more particularly to provide a shock absorber applied between the shoe outsole and the midsole phase.

종래에는 신발용 솔(SOLE), 즉 아웃솔(OUTSOLE)과 미드솔(MIDSOLE)에는 보행시 발에 가해지는 충격 등을 완충코자 다양한 완충장치가 적용되고 있었다. 그러한 완충장치중 대표적인 수단이 솔에 각각 에어가 출입할 수 있는 에어챔버를 형성하여 에어가 착지시마다 출입할 수 있도록 하여 완충을 행하거나 또는 폐쇄된 에어챔버를 별도의 튜브체로 형성하여 착지시에 튜브가 신축되면서 완충을 행하도록 한 것 등이 있었다.Conventionally, various shock absorbers have been applied to shock absorbers, such as outsoles and midsoles, for shocks applied to the foot when walking. Representative means of such a shock absorber forms an air chamber through which the air can enter and exit each of the soles so that the air can enter and exit each landing, or a closed air chamber is formed into a separate tube body to form a tube at the time of landing. There was such a thing that the buffer was made to expand and contract.

그리고 아웃솔에 요입형의 에어챔버를 형성하여 미드솔과 일체로 접착성형하면 에어챔버가 폐쇄형의 에어챔버로 구성되어 완충을 행하도록 한 것 등이 있는 바, 이러한 아웃솔과 미드솔 독립형의 완충장치는 제한된 치수내에서 에어챔버의 치수를 증대하는 데에는 한계가 있었고, 그로 인한 완충의 효과 역시 제한될 수 밖에 없었으며, 또한 근자에 가장 많이 적용되고 있는 별도의 독립된 에어챔버를 제작 사용할 시는 이로 인한 신발의 제조원가 앙등의 가장 큰 원인이 되고 있는 것이다.In addition, when the insole is formed with a concave-type air chamber and is integrally bonded with the midsole, the air chamber is configured as a closed air chamber to cushion the bar. The outsole and midsole independent shock absorbers are limited. There was a limit to increasing the dimensions of the air chamber within the dimensions, and the effect of the cushioning was limited. Also, when manufacturing and using a separate air chamber that is most applied to the roots, It is the biggest cause of manufacturing cost improvement.

이에 본 고안에서는 상술한 바와 같은 기존의 신발용 완충장치가 갖는 완충효과의 한계를 극복할 수 있도록 극히 간단한 구성의 신발용 솔의 완충장치를 제공코자 하는 것으로서, 특히 미드솔과 아웃솔 양자를 동시에 활용하는 완충장치를 제공코자 한다.Therefore, the present invention is to provide a shock absorber of the shoe sole of a very simple configuration to overcome the limitation of the cushioning effect of the conventional shoe shock absorber as described above, in particular to utilize both the midsole and the outsole at the same time To provide a shock absorber.

도 1은 본 고안에서 개시하는 신발용 솔(sole) 완충장치(cushion system)의 바람직한 일실시예를 보인 분해사시도이며, 도 2는 결합상태 단면도로서, 통상 고무 등으로 성형되는 신발용 아웃솔(1)의 상면부와 EVA스폰지 등으로 성형되는 미드솔(2)의 저면부에는 각각 대칭형의 요입실(3, 4)을 형성하고, 상기 요입실(3, 4)의 단부가 서로 일치하도록 아웃솔(1)과 미드솔(2)을 접착제를 사용하여 접착구성함으로서 상기 요입실(3, 4)이 폐쇄형의 에어챔버(5)를 형성토록 한다. 상기 에어챔버(5)는 다양한 형상이 개시될 수 있지만 토우(tow)와 힐(hill) 부분에 적정의 체적을 갖는 에어챔버(5)를 형성하고, 이들을 연결하는 통로(2A)를 형성한 예를 도면상에서는 예시하고 있다.1 is an exploded perspective view showing a preferred embodiment of a shoe sole cushion (sole) cushion system disclosed in the present invention, Figure 2 is a cross-sectional view of the bonded state, usually a shoe outsole (1) Symmetric indenting chambers 3 and 4 are formed on the upper surface of the upper surface and the bottom of the midsole 2 formed of EVA sponge or the like, and the outsole 1 is formed so that the ends of the indenting chambers 3 and 4 coincide with each other. ) And the midsole 2 are bonded to each other using an adhesive so that the urinary chambers 3 and 4 form a closed air chamber 5. Although the air chamber 5 may have various shapes, an example in which an air chamber 5 having an appropriate volume is formed in the tow and the hill, and a passage 2A connecting them is formed. Is illustrated on the drawing.

한편 미드솔(2)에는 도 5와 같이 에어통로(2A)를 없애더라도 연접된 아웃솔(1)의 에어통로(2A)만으로도 본 기능을 수행하는데는 아무런 문제가 없는 것이다.Meanwhile, even if the air passage 2A is removed from the midsole 2 as shown in FIG. 5, only the air passage 2A of the connected outsole 1 has no problem in performing this function.

그리고 상기 미드솔(2)의 요입실(4)을 커버링할 수 있는 TPU시트지(6)는 미드솔(2) 프레스 성형시 동시에 인서트몰딩 처리로 접착되어 에어챔버(5)의 효과를 극대화하고 솔의 뒤틀림방지 및 신발의 중심설정, 견고성을 배가할 수 있도록 한 것이다.And the TPU sheet 6, which can cover the indentation chamber 4 of the midsole 2, is bonded by insert molding at the same time during the press forming of the midsole 2 to maximize the effect of the air chamber 5 and to warp the sole. Prevention and centering of the shoes, it is intended to double the firmness.

도면중의 부호 7은 접착층을 도시한 것이다.Reference numeral 7 in the figure shows an adhesive layer.

상기와 같이 구성될 수 있는 본 고안은 아웃솔(1)과 미드솔(2)의 연접면부에 대칭형의 요입실(3, 4)을 형성하고 양자를 서로 접착함으로서 상기 요입실(3, 4)은 폐쇄형의 에어챔버(5)를 형성하게 되고, 이는 신발에 적용할 경우 신발 보행자가 착지시에 발에 가해지는 충격을 보다 에어챔버(5)가 신축되면서 완충을 수행하게 되어 보행감 향상과 함께 발에 가해지는 충격으로 인한 관절손상이나 발의 피로도를 대폭 줄일 수 있는 것이다.The present invention, which can be configured as described above, forms the symmetric indenting chambers 3 and 4 at the joint surfaces of the outsole 1 and the midsole 2 and adheres them to each other so that the indenting chambers 3 and 4 are closed. The air chamber 5 of the type is formed, and when applied to the shoe, the air chamber 5 expands and cushions the foot when the pedestrian of the shoe lands. It can significantly reduce joint fatigue or foot fatigue caused by the impact.

이상에서 상세히 살펴본 바와 같이 본 고안은 아웃솔(1)과 미드솔(2)의 연접면부에 상호 대칭형의 요입실(3, 4)을 형성하고, TPU시트지(6)를 미드솔(2) 성형시 동시 인서트몰딩으로 부착하여 양자를 일체로 접착구성함으로서 폐쇄형으로 이루어지는 에어챔버(5)가 보행시 신축되면서 완충역할을 극대화할 수 있는 것이며, 특히 제한된 아웃솔(1)과 미드솔(2)의 치수내에서 큰 체적의 에어챔버(5)를 형성함으로서 종래의 에어챔버를 가진 솔에 비하여 월등한 완충기능을 제공받을 수 있는 것이며, TPU시트지(6)는 요입실(3, 4)의 형성으로 인한 솔 전체의 뒤틀림이나 중심 이탈, 내구성저하 등과 같은 문제를 해결해 줌으로서 제품의 내구성 역시 배가할 수 있는 등 그 기대되는 효과가 다대한 고안이다.As described in detail above, the present invention forms mutually symmetric indenting chambers 3 and 4 at the joint surfaces of the outsole 1 and the midsole 2, and simultaneously inserts the TPU sheet 6 into the midsole 2. It is possible to maximize the buffering role as the closed air chamber 5 is stretched when walking by attaching molding and bonding the two together integrally, especially in the limited size of the outsole 1 and the midsole 2. By forming the volume of the air chamber 5, it is possible to provide a superior cushioning function as compared to the sole having a conventional air chamber, the TPU sheet 6 is the entire sole of the sole due to the formation of the concave chamber (3, 4) It solves problems such as warping, defocusing, and durability, which can double the durability of the product.
