본 발명은 신발창의 뒤꿈치 내부에 삽입되어 보행 시 내부 공기를 신발 외부로 강제 배출(신발 내부로 강제 공급)하여 통풍시킬 수 있도록 한 신발용 에어펌프에 관한 것으로서, 보다 구체적으로는 구성을 간소화 하면서도 기능성이 우수한 염가의 신발용 에어펌프를 제공코자 한 것이다.The present invention relates to a shoe air pump which is inserted into the heel of the shoe sole to allow ventilation of the internal air to the outside of the shoe when walking (forcibly fed into the shoe), and more specifically, to simplify the configuration and functional It is to provide a low cost shoe air pump.

신발내의 공기 유통이 어려워 땀과 습기를 외부로 배출할 수 없기 때문에 항시 신발이 습하여 각종 세균이 번식하게 되고, 그로 인해 악취(발 냄새) 및 무좀과 같은 피부병 발생의 원인이 되었다.Since the air in the shoes is difficult to distribute sweat and moisture to the outside, the shoes are always wet, and various germs multiply, which causes odors (foot odors) and skin diseases such as athlete's foot.

근자에는 이러한 문제점을 해결할 목적으로 통풍 신발이 개발되고 있으며, 대표적으로는 신발 뒷굽에 흡입관과 배출관에 각각 체크밸브가 결합 구성된 에어펌프를 내입하여 보행하는 족압에 의해 내부공기를 흡입하여 신발 외부로 배출하거나 또는 외부 공기를 신발 내부로 공급하게 한 것과, 신발밑창에 적당한 크기의 함실을 만들고 이 함실에 체크밸브가 결합 구성된 흡입관과 배출관에 배관 설치하고, 함실을 족압에 의해 가압되는 커버로 밀폐하여 구성한 것 등이다.In recent years, ventilated shoes have been developed for the purpose of solving these problems, and typically, the air pump is configured by injecting an air pump composed of a check valve in each of the suction pipe and the discharge pipe of the shoe heel to discharge internal air by the foot pressure. Or by supplying outside air to the inside of the shoe, making a compartment of a suitable size in the sole of the shoe, and installing the piping in the suction and discharge pipes in which the check valve is coupled to the compartment, and sealing the compartment with a cover pressurized by foot pressure. Etc.

상기와 같은 종래 신발용 에어펌프는 신발 내부 공기를 유통시켜 신발 내부의 습도를 조절하는 기능과, 보행 시 에어펌프에 의한 쿠션력 제공으로 착화감을 향상시킬 수 있어 대부분의 신발에서 채택 사용되고 있다.The conventional air pump for shoes as described above is used in most shoes to improve the ignition feeling by providing a cushion force by the air pump and the function of controlling the humidity in the shoes by circulating the air inside the shoe.

그러나 상기한 바와 같은 에어펌프의 경우 부품이 많아 조립 등에 따른 비용이 많이 들고, 생산성이 떨어지며, 제조과정에서 많은 불량이 발생하게 되는 등의 문제점이 있었고, 그로 인해 신발 가격도 동반 상승시키게 되어 가격 경쟁력을 저하시키게 되는 등 다수의 문제점이 있었다.However, in the case of the air pump as described above, there are a lot of parts, such as high costs due to the assembly, productivity is low, there are problems such as a lot of defects occur in the manufacturing process, thereby increasing the price of the shoes accompanied by price competitiveness There are a number of problems, such as lowering.

이에 본 발명자는 일반적으로 널리 사용되고 있는 신발용 에어펌프의 제반 문제점을 해결코자 연구한 것이다.Therefore, the present inventors have studied to solve all the problems of the air pump for shoes that are generally widely used.

즉, 본 발명에서는 종래와 같이 체크밸브를 별도 제작 사용하지 않고 사출성형에서 성형되는 상하 분할되는 한 쌍의 구성부재를 단순히 결합하는 공정만으로 펌핑력이 우수한 에어펌프를 완성할 수 있게 함으로 해서 부품의 간소화로 제조원가 및 작업능률을 획기적으로 향상시킬 수 있는 신발용 에어펌프를 제공함에 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.
That is, in the present invention, the air pump having excellent pumping force can be completed by simply combining a pair of upper and lower constituent members which are molded in injection molding without using a check valve separately. The present invention has been completed with the technical problem of the present invention by providing an air pump for shoes that can significantly improve the manufacturing cost and work efficiency by simplification.

도 1은 본 발명의 바람직한 일 실시예를 보인 사시도를 도시한 것이고, 도 2는 본 발명의 분해 사시도, 도 3은 본 발명의 결합상태 단면도, 도 4는 본 발명의 일 사용상태 예시 단면도를 도시한 것으로서, 이하에서 본 발명의 구성을 설명하기로 한다.1 is a perspective view showing a preferred embodiment of the present invention, Figure 2 is an exploded perspective view of the present invention, Figure 3 is a cross-sectional view of the coupling state of the present invention, Figure 4 is a cross-sectional view illustrating an exemplary use state of the present invention. As one, the configuration of the present invention will be described below.

본 발명에서 제공하는 신발용 에어펌프(1)는 공간부(3) 양측으로 상측이 개방되고 단면이 직사각형상인 흡입로(4)와 배출로(5)가 일체 형성된 하측부재(2)와, 상기 공간부(3)와 대응하는 공간부(7) 양측으로 흡입로(4)와 배출로(5)를 커버링하 는 덮개판(8)(9)이 일체 형성되고 하측부재(2)와 수밀되도록 견고하게 접착 결합하는 상측부재(6)로 구성된다.The air pump 1 for shoes provided by the present invention includes a lower member 2 having an upper side open to both sides of the space portion 3 and a rectangular cross section having an inlet passage 4 and an outlet passage 5 formed therein, and The cover plates 8 and 9, which cover the suction passage 4 and the discharge passage 5, are integrally formed on both sides of the space portion 7 and the corresponding space portion 7 so as to be watertight with the lower member 2. It consists of an upper member (6) firmly adhesively bonded.

상기 하측 및 상측부재(2)(6)의 공간부(3)(7)에 의해 밀폐 형성된 에어챔버(A) 내에는 족압에 의해 에어펌프(1)가 작동할 때 신속한 복원력을 제공하는 복원수단으로 하측 및 상측부재(2)(6)에는 서로 대칭하는 복원돌기(10)(11)를 형성한다.Restoration means for providing rapid restoring force when the air pump 1 is operated by foot pressure in the air chamber A sealed by the space portions 3 and 7 of the lower and upper members 2 and 6. As a result, the lower and upper members 2 and 6 are provided with restoration protrusions 10 and 11 symmetric to each other.

그리고 상기 흡입로(4)와 배출로(5)를 커버링하는 덮개판(8)(9)의 아래쪽으로는 흡입로(4)와 배출로(5)의 측벽과 바닥에 긴밀하게 밀착되고 에어챔버(A)가 족압에 의해 가압 및 복원함에 따라서 개폐되게 일측 방향으로 경사지는 체크변(12)(13)을 형성하며, 상기 체크변(12)(13) 단면은 덮개판(8)(9)측이 두껍고 선단쪽으로 점차적으로 얇아져 뾰족하게 형성된 역삼각형으로 형성한다.The lower side of the cover plates 8 and 9 covering the suction passage 4 and the discharge passage 5 closely adheres to the side walls and the bottom of the suction passage 4 and the discharge passage 5, and the air chamber. (A) forms check edges 12 and 13 that are inclined in one direction to open and close as they are pressed and restored by foot pressure, and the check edges 12 and 13 end faces cover plates 8 and 9. The side is thick and gradually thinned toward the tip to form a sharp inverted triangle.

즉, 상기 체크변(12)(13) 중 흡입로(4) 측에 위치하는 것은 에어챔버(A) 측으로 소정각도로 경사지게 형성하며, 배출로(5)측에 위치하는 것은 에어챔버(A) 반대측으로 소정각도로 경사지게 형성한다.That is, the check valves 12 and 13 located on the suction path 4 side are formed to be inclined at a predetermined angle toward the air chamber A side, and the air valve A located on the discharge path 5 side. It is formed to be inclined at a predetermined angle to the opposite side.

한편 상기 배출로(5)에는 체크변(13)이 닫칠 때 에어챔버(A) 쪽으로 과도하게 회동되는 것을 방지할 수 있게 스토퍼(14)를 돌출 형성한다.Meanwhile, the stopper 14 protrudes from the discharge path 5 so as to prevent excessive rotation of the check valve 13 toward the air chamber A.

도면 중 미설명 부호 15는 신발, 16, 17은 흡입로(4)와 배출로(5)가 각각 연결되는 흡입관 및 배출관을 도시한 것이다.In the drawings, reference numeral 15 denotes a shoe, and 16 and 17 show suction pipes and discharge pipes to which the suction path 4 and the discharge path 5 are respectively connected.

이상과 같이 구성되는 본 발명 신발용 에어펌프(1)는 도 4에 도시된 바와 같 이 신발(15)의 내부와 외부로 연결되어 있는 흡입관(16) 및 배출관(17)에 흡입로(4)와 배출로(5)가 연결되도록 뒷굽 내부에 설치하는 것으로서, 이하에서 본 발명의 사용에 따른 작용 등을 설명한다.Shoe air pump 1 of the present invention constituted as described above is the suction passage 4 to the suction pipe 16 and the discharge pipe 17 connected to the inside and outside of the shoe 15 as shown in FIG. As installed in the heel to be connected to the discharge passage 5, the operation and the like according to the use of the present invention will be described below.

본 발명은 하측부재(2) 상측으로 상측부재(6)를 열접착 등의 방법으로 결합하기만 하면 조립 완성되는 것으로서, 본 발명이 설치되는 신발(15)을 착화한 상태에서 보행을 하게 되면 족압에 의해 에어챔버(A)가 가압 및 복원 작동을 반복하면서 종래 에어펌프와 같이 신발(15) 내부 공기를 강제 흡입하여 신발(15) 외부로 배출하게 되는 것이다.The present invention is to complete the assembly simply by combining the upper member 6 to the upper side of the lower member 2 by a method such as thermal bonding, the foot pressure when walking in the ignition state of the shoe 15 is installed the present invention By the air chamber (A) by repeatedly pressing and restoring the operation is forced to suck the air in the shoe 15, like the conventional air pump to discharge the shoe 15 outside.

즉, 본 발명에 의하면 족압이 상측부재(6)에 가해질 때 에어챔버(A)가 가압되는데 이때 배출로(5)에 접하고 있는 에어챔버(A) 반대측으로 경사진 체크변(13)이 자연스럽게 회동되어 배출로(5)측으로 개방이 이루어져 에어챔버(A) 내의 공기가 배출된다.(이때 흡입로(4)측 체크변(12)은 닫힌 상태를 유지하게 된다.) That is, according to the present invention, when the foot pressure is applied to the upper member 6, the air chamber A is pressurized. At this time, the check valve 13 inclined to the opposite side of the air chamber A in contact with the discharge path 5 naturally rotates. Then, the air is released from the air chamber A by the opening to the discharge passage 5 side. (At this time, the check valve 12 on the suction passage 4 maintains the closed state.)

상기한 상태에서 에어챔버(A)에 가해지는 족압이 해지되면 에어챔버(A) 내에 마련되어 있는 복원돌기(10)(11)의 복원력에 의해 상측부재(6)가 원상태로 복원되며 이 과정에서 에어챔버(A) 내에서 배출로(5) 측으로 배출한 공기만큼을 필요로 하는 힘이 발생하게 되는데 이때 흡입로(4)와 배출로(5)에 위치하는 양측 체크변(12)(13)은 에어챔버(A)측으로 강하게 당겨지게 된다.When the foot pressure applied to the air chamber A is released in the above state, the upper member 6 is restored to its original state by the restoring force of the restoring protrusions 10 and 11 provided in the air chamber A. In the chamber A, a force that requires as much air as is discharged to the discharge passage 5 side is generated. At this time, both check valves 12 and 13 positioned at the suction passage 4 and the discharge passage 5 are It is strongly pulled toward the air chamber A side.

따라서 상기와 같이 에어챔버(A)의 복원에 의해 흡입력이 발생할 때 배출로(5)측 체크변(13)은 에어챔버(A)측으로 회동되어 배출로(5)를 차단하게 되고 반대로 흡입로(4)측 체크변(12)은 에어챔버(A)측으로 개방되어 흡입관(16)을 통해 신발 (15) 내부 공기를 흡입하게 되는 것이다.Therefore, when the suction force is generated by the restoration of the air chamber A as described above, the discharge path 5 side check valve 13 is rotated to the air chamber A side to block the discharge path 5 and vice versa. 4) The side check edge 12 is opened to the air chamber (A) side to suck the air inside the shoe 15 through the suction pipe (16).

이상과 같이 구성 및 작용하는 본 발명의 신발용 에어펌프(1)는 종래와 같이 별도 구성되는 체크밸브를 결합하지 않고 상측부재(6)에 일체 형성되어 있는 체크변(12)(13)으로 공기의 흐름을 차단할 수 있게 한 것으로서, 본 발명에 의하면 구성부품을 간소화 할 수 있어 제조비용을 획기적으로 절감할 수 있고, 부품조립에 따른 공정을 대폭 줄일 수 있어 생산성 향상을 기대할 수 있는 것이며, 조립에 따른 불량률도 대폭 줄일 수 있는 등 기대 이상의 효과를 제공하는 매우 유용한 발명이다.The shoe air pump 1 of the present invention constructed and acting as described above is provided with check valves 12 and 13 that are integrally formed on the upper member 6 without engaging a check valve that is separately configured as in the prior art. According to the present invention, the components can be simplified, the manufacturing cost can be drastically reduced, and the manufacturing process can be greatly reduced, and the productivity can be expected to be improved. It is a very useful invention to provide more than expected effect, such as significantly reduce the defective rate.
