Description

방독면용 고리유닛Gas mask ring unit
본 발명은 방독면에 관한 것으로, 보다 상세하게는 후두부 커버의 상측 결합끈이 감겨져 고정되는 안면마스크의 연결고리에 대한 지지강성을 대폭 보강할 뿐만 아니라 그 제조를 간편하게 하여 제조단가를 절감할 수 있는 방독면용 고리유닛에 관한 것이다. The present invention relates to a gas mask, and more particularly, a gas mask that can greatly reduce the manufacturing cost by simplifying the manufacturing of the face mask to which the upper coupling straps of the rear head cover are wound and fixed. It relates to a ring unit for.
널리 주지된 바와 같이, 방독면은 화학전이나 생물학전 또는 방사능전 등의 위급상황에서 발생되는 유독성 화학가스와 같은 유독물질이 인체에 유입되지 않도록 하기 위하여 안면에 착용하는 것이다. 이러한 방독면은 착용자를 보호하여 착용자를 오염지역에서 안전지역으로 대피시킬 수 있다.As is widely known, gas masks are worn on the face to prevent toxic substances such as toxic chemical gases generated in emergencies such as chemical warfare, biological warfare or radioactive warfare. Such gas masks can protect the wearer and evacuate the wearer from the contaminated area to the safe area.
이러한 방독면은 안면부를 밀폐하는 안면마스크와, 안면마스크의 상부에 마련된 투시창과, 안면마스크의 측방에 마련된 정화통과, 안면마스크의 하부 중앙부에 마련된 배기유닛 등을 가진다. The gas mask has a face mask that seals the face part, a see-through window provided on an upper part of the face mask, a purifying container provided on the side of the face mask, an exhaust unit provided on the lower center of the face mask, and the like.
그리고, 안면마스크에는 착용자의 후두부를 감싸는 후두부 커버가 분리가능하게 연결되고, 또한 필요에 따라 안면마스크에 연결된 후두부 커버 위로 두건 또는 헬멧 등이 착용될 수 있다.In addition, the face mask may be detachably connected to the back head cover surrounding the back of the wearer, and a hood or a helmet may be worn over the back head cover connected to the face mask as necessary.
이러한 후두부 커버의 상측가장자리에는 복수의 상측 결합끈이 외측으로 연장되고, 후두부 커버의 좌우 양측가장자리에는 복수의 측방 결합끈이 연장된다. 이에 대응하여 안면마스크의 좌우 양측가장자리에는 후두부 커버의 측방 결합끈이 분리가능하게 고정되는 버클이 마련되고, 안면마스크의 상부가장자리에는 상측 결합끈이 분리가능하게 고정되는 고리가 마련된다. A plurality of upper coupling straps extend outwardly on the upper edge of the back head cover, and a plurality of side coupling straps extend on both left and right edges of the posterior head cover. Correspondingly, left and right side edges of the face mask are provided with a buckle to which the side coupling straps of the rear head cover are separably fixed, and a top ring of the face mask is detachably fixed to the upper coupling straps.
여기서, 상측 결합끈은 그 단부에 밸크로 파스너가 마련되고, 상측 결합끈의 단부가 안면마스크의 고리에 감겨진 밸크로 패스너가 결합됨에 따라 고리에 고정된다.Here, the upper coupling strap is provided with a Velcro fastener at its end, and the end of the upper coupling strap is fixed to the hook as the Velcro fastener is wound around the loop of the face mask.
하지만, 종래의 방독면은 후두부커버의 상측 결합끈이 고리에 감겨짐에 따라 그 두께가 두꺼워져 상측 결합끈의 감겨진 부분은 고리의 두께방향으로 돌출되고, 이로 인해 그 돌출된 부분이 후두부 커버 위로 착용되는 두건에 걸리거나 헬멧에 의해 가압되어 두피를 자극하면서 통증을 유발시키는 문제점이 있었다.However, in the conventional gas mask, as the upper coupling strap of the rear head cover is wound on the hook, the thickness thereof becomes thicker, so that the wound portion of the upper coupling strap protrudes in the thickness direction of the hook, and thus the protruding portion is placed on the back of the posterior head cover. There was a problem of causing pain while the head is worn or pressed by a helmet to stimulate the scalp.
이러한 단점을 극복하기 위하여 본 발명의 출원인은 안면마스크의 연결고리(걸림링)에 후두부 커버의 상측 결합끈이 감져질 때 상측 결합끈이 연결고리의 두께방향으로 돌출됨을 방지함으로써 두건에 걸리거나 헬멧에 의해 가압되어 통증이 유발되는 단점을 해결한 구성을 등록특허 10-1278436호(2013.06.24, 이하 '선행특허'라 함)에서 제안한 바 있다. Applicants of the present invention to overcome this disadvantage is to catch the hood or helmet by preventing the upper coupling strap protrudes in the thickness direction of the connecting ring when the upper coupling strap of the rear head cover is wound on the connecting ring (hook ring) of the face mask It has been proposed in the Patent Registration No. 10-1278436 (2013.06.24, hereinafter referred to as a 'prior patent') to solve the disadvantage that the pain caused by being pressed by.
하지만, 상술한 선행특허에 의하면, 연결고리(걸림링) 내에 보강재인 인서트가 내장되어 있음에도 불구하고 안면마스크의 상측 가장자리에서 동일체로 돌출되게 형성됨에 따라 후두부 커버의 상측 결합끈이 반복적으로 당겨질 경우 연결고리가 쉽게 파손 내지 파손되어 방독면의 수명이 짧아지는 단점이 있었다. However, according to the above-described prior patent, even though the insert is a reinforcing material in the connecting ring (locking ring) is formed to protrude into the same body from the upper edge of the face mask as the upper coupling strap of the back head cover is repeatedly drawn The ring was easily broken or broken, and thus shortened the life of the gas mask.
또한, 종래의 방독면은 연결고리(걸림링) 내에 보강재를 별도로 인서트 성형하여야 함에 따라 그 제조공정이 복잡해져 제조단가를 상승시키는 요인이 된다. In addition, according to the conventional gas mask surface, inserting the reinforcement in the connecting ring (locking ring) separately, the manufacturing process is complicated, which increases the manufacturing cost.
