본 발명의 헬멧 또는 띠연결 구조에 따르면, 예컨대 고정띠에 형성된 암형 체결구와 연결띠에 형성된 수형 체결구를 결합암에 있어, 암형 체결구로 삽입되는 수형 체결구의 헤드부에 대해 암형 체결구의 스냅부가 스냅 반발을 일으키는 힘의 방향은 고정띠의 표면에 직각을 이루어, 암형 체결구와 수형 체결구가 결합된 후, 암형 체결구의 걸림부에서 수형 체결구의 헤드부를 빼내기 위해 헤드부에 걸리는 외력의 방향 즉, 고정띠의 표면과 평행한 하방과 직각을 이룬다. According to the helmet or the belt connecting structure of the present invention, for example, the female fastener formed in the fastening band and the male fastener formed in the connecting band in the coupling arm, the snap portion of the female fastener snaps against the head of the male fastener inserted into the female fastener. The direction of the force generated is at right angles to the surface of the fastening band, after the female fastener and the male fastener are engaged, the direction of the external force applied to the head to pull the head of the male fastener from the locking part of the female fastener, that is, It is perpendicular to the surface below and parallel to the surface.

따라서, 수형 체결구는 암형 체결구에 결합된 후, 고정띠 표면과 직각인 방향으로 연결띠에 가해지는 외력에 대해서는 헤드부가 강체인 걸림부에 의해 구속되므로, 또 고정띠 표면과 평행한 방향으로 연결띠에 가해지는 외력에 대해서는 헤드부를 구속하는 스냅부가 스냅 탄력을 갖지 않는 방향으로 헤드부를 구속하므로, 스냅 탄력에 의한 변형을 일으켜 걸림부로부터 분리될 수 있는 여지가 없게 된다.Therefore, the male fastener is coupled to the female fastener, and then the head part is restrained by the rigid body engaging portion for the external force applied to the connecting band in a direction perpendicular to the fixing belt surface, and the connecting fastening member is parallel to the fixing belt surface. With respect to the external force applied, the snap portion which restrains the head portion restrains the head portion in a direction in which the snap portion does not have snap elasticity, so that there is no room for the deformation caused by snap elasticity to be separated from the locking portion.

따라서, 고정띠와 연결띠는 외력에 의해서는 분리될 수 없는 견고하고 영구적인 띠연결 구조에 의해 결합되면서도, 마찬가지로 영구 결합인 리벳 등과는 달리 필요에 따라서는 스냅부를 밖으로 밀어내는 조작에 의해 간단히 분리해 낼 수 있으므로, 헬멧 특히 고정띠와 머리띠 또는 연결띠 간의 결합에 따른 내구성능 및 조립성을 동시에 만족시킬 수 있게 된다.Therefore, the fixing band and the connecting band are separated by a rigid and permanent band connecting structure which cannot be separated by external force, but unlike the permanent rivets, etc. Since it can be done, it is possible to satisfy the durability and assembly performance at the same time by the combination between the helmet, in particular the fixing belt and the headband or connecting strap.

At this time, the stem portion 31 of the male fastener 21 enters along the locking groove 47 of the locking portion 43.

곧이어, 도 5 및 도 6에 도시된 바와 같이, 암형 체결구(23)의 걸림부(43) 몸통(45) 안으로 수형 체결구(21)의 헤드부(33)가 밀려들어가면, 헤드부(33)에 의해 바깥쪽으로 밀려 있던 스냅부(41)는 스냅식으로 원위치에 복귀하며, 원위치된 스냅부(41)에 의해 헤드부(33)는 몸통(45)의 포켓(49)에 수용된 상태로 구속된다. 5 and 6, when the head part 33 of the male fastener 21 is pushed into the body 45 of the locking part 43 of the female fastener 23, the head part 33 The snap portion 41 pushed outwards by means of snap) returns to its original position in a snap manner, and the head portion 33 is restrained in a state of being accommodated in the pocket 49 of the body 45 by the snap portion 41 in place. do.

이렇게 해서, 띠연결 구조(20)의 암수형 체결구(23,21)가 도 5에 도시된 것처럼 체결 완료되면, 고정띠(5)의 표면에 직각 방향으로 연결띠(25)에 가해지는 외력에 대해서는 걸림부(43)의 역U자형 몸통(45)이 헤드부(33)를 저지하여 연결띠(25)의 분리를 저지하고, 고정띠(5)의 표면에 평행한 방향에서 하방으로 연결띠(25)에 가해지는 외력에 대해서는 스냅부(41) 선단이 헤드부(33)를 저지한다. 특히, 고정띠(5) 표면에 직각 방향으로 외력이 가해지는 경우, 연결띠(25)에 가해지는 외력의 방향이 스냅부(41)의 스냅반력을 일으키는 힘의 방향과 거의 직각을 이루므로, 외력의 방향과 스냅반력의 방향이 동일하여 외력을 조금만 증대시켜도 스냅결합이 쉽게 분리되는 종래의 스냅 결합과는 달리, 본 발명에 따른 암수형 체결구(23,21)의 결합은 스냅부(41)를 고정띠(5)의 안쪽에서 바깥쪽으로 손가락 등에 의해 눌러 도 7과 같이 변형시키기 밖으로 밀어내기 전에는 아무리 연결띠(25)를 고정띠(5)로부터 잡아당겨도 연결띠(25)를 고정띠(5)에서 분리시키지 못한다. 따라서, 본 발명 띠연결 구조(20)는 스냅결합 구조임에도 불구하고 리벳 등과 같은 기존의 체결구조와 같이 영구적으로 결합을 유지할 수 있게 된다.In this way, when the male and female fasteners 23 and 21 of the belt connection structure 20 are fastened as shown in FIG. 5, an external force applied to the connection band 25 in a direction perpendicular to the surface of the fixing band 5. In contrast, the inverted U-shaped body 45 of the locking portion 43 prevents the head portion 33 from interfering with the separation of the coupling strip 25, and is connected downward in a direction parallel to the surface of the fixing belt 5. Regarding the external force applied to the belt 25, the tip of the snap portion 41 blocks the head portion 33. In particular, when an external force is applied to the surface of the fixing band 5 at right angles, the direction of the external force applied to the connecting band 25 is substantially perpendicular to the direction of the force causing the snap reaction force of the snap portion 41. Unlike the conventional snap coupling, in which the direction of the external force and the direction of the snap reaction force are the same, and the snap coupling is easily separated even if the external force is slightly increased, the coupling of the male and female fasteners 23 and 21 according to the present invention is a snap portion 41. ) By pressing with a finger or the like from the inside of the fixing band 5 to the deformation as shown in FIG. 7, no matter how much the connecting strap 25 is pulled from the fixing belt 5, the fixing strap 25 is fixed. Can not be separated in (5). Therefore, the present invention, the band connection structure 20 is able to maintain the bond permanently, like a conventional fastening structure such as rivets, despite the snap coupling structure.
