본 발명은 무소음 맨홀의 잠금장치에 관한 것으로서, 특히 맨홀 덮개에 구성된 잠금수단이 탄지스프링에 의해 탄력설치되게 함과 동시에, 덮개의 잠금편이 걸려지는 받침대의 받침편 전부분에 걸쳐 요철이 형성되게 하므로서, 덮개에 구성된 잠금편이 받침대의 받침편과 걸림이 이루어진 상태에서는 인위적으로 잠금을 해지시키지 않는한 잠금이 이완되거나 풀리지 않게 구성한 것이다.The present invention relates to a lock device for a noiseless manhole, and in particular, the locking means configured in the manhole cover is elastically installed by the tanger spring, and at the same time, so that the unevenness is formed over the entire portion of the support piece on which the locking piece of the cover is caught. , The locking piece configured in the cover is configured so that the lock is not relaxed or loosened unless the lock is artificially released in a state where the locking piece is engaged with the support piece of the pedestal.

잠금장치가 구성된 맨홀에 대하여서는 여러구성들의 맨홀들이 제공된바 있다.Manholes of various configurations have been provided for manholes with locking devices.

일예로서 덮개에 구성된 잠금편이 회전하여 받침대의 받침편에 걸려지게 하므로서 잠금이 이루어지게 한 수단이 제공된바 있으나, 이러한 잠금수단은 덮개에 구성된 잠금편과 받침대의 받침편 사이에 간격의 오차없이 정확히 일치되어야 하나, 주물성형하는 맨홀의 특성상 정밀제작이 어렵기 때문에 받침편과 잠금편 사이에 공간이 생기면서 소음이 발생하게 될 뿐 아니라 충격이나 진동에 의해 잠금이 풀리게 될 우려가 있는 등의 단점이 있는 것이었다.As an example, a means for locking is provided by rotating the locking piece configured on the cover to be hung on the support piece of the pedestal, but the locking means is exactly matched without any gap between the locking piece configured on the cover and the support piece of the pedestal. However, due to the nature of casting manholes, it is difficult to precisely fabricate them. Therefore, space is created between the supporting piece and the locking piece, which causes noise, and there is a possibility that the lock may be released by shock or vibration. Was.

이러한 문제를 해결하기 위한 수단으로서 특허 제522295호 "맨홀 뚜껑의 잠 금장치"로 특허된 맨홀제품이 제공된바 있다.As a means to solve this problem has been provided a manhole product patented in the patent "522295" manhole cover locking device ".

즉 도 11에서와 같이 뚜껑틀(40) 상에 뚜껑(20)이 결합되는 맨홀(가)에 잠금장치를 구성함에 있어서, 뚜껑(20) 일측에 축공(22)을 구성하고, 상기 축공(22) 하단에 작동요부(21)를 구성하고, 작동요부(21) 단부에 밀폐턱(23)을 구성하고, 상기 축공(22)에 요철(12)이 형성된 잠금원판(11)과, 축봉(13) 및 걸림대(14)로 구성된 잠금쇠(10)를 설치하되, 잠금쇠(10)의 축봉(13)이 축공(22)에 끼워지고, 잠금원판(11)이 작동요부(21)에 위치되게 하였으며, 이때 잠금원판(11)은 일측으로 경사지게 구성되어 있다.That is, in the configuration of the locking device in the manhole (A) is coupled to the lid 20 on the lid frame 40, as shown in Figure 11, to configure the shaft hole 22 on one side of the lid 20, the shaft hole 22 Lock base plate 11 and the shaft 13 formed at the lower end of the operating recess 21, the closing jaw 23 at the end of the operating recess 21, the concave-convex 12 is formed in the shaft hole (22). ) And the fastener (10) consisting of a hanger 14, the shaft rod 13 of the fastener 10 is fitted into the shaft hole 22, the locking disc 11 is positioned in the operation recess 21, At this time, the locking disc 11 is configured to be inclined to one side.

상기 뚜껑(20)의 잠금쇠(10)와 결합되는 뚜껑틀(40)에는 안착홈(44)을 구성하여 뚜껑(20)이 안치되게 하고, 안착홈(44) 일측에는 걸림돌부(42)를 돌출구성하여 하단에 잠금요부(41)가 구성되게 하므로서 잠금쇠(10)의 잠금원판(11)이 걸려질 수 있게 하고, 상기 잠금요부(41) 아랫쪽에는 밀폐돌기(43)를 구성하고, 상기 밀폐돌기(43) 단부에 밀폐링(30)을 끼워 뚜껑(20)의 밀폐턱(23)이 위치되게 한 것이다.The lid frame 40 is coupled to the clamping pad 10 of the lid 20 to form a seating groove 44 so that the lid 20 is settled, protruding the locking protrusion 42 on one side of the seating groove 44. By configuring the locking recess 41 at the lower end so that the locking disc 11 of the clamp 10 can be caught, and to form the sealing protrusion 43 below the locking recess 41, the sealing protrusion (43) The sealing ring 30 is fitted to the end so that the sealing jaw 23 of the lid 20 is positioned.

따라서 상기한 구성의 맨홀 뚜껑 잠금장치는 뚜껑(20)의 다수곳에 구성된 잠금쇠(10)를 회전시키면 잠금원판(11)이 회전하고, 상기 잠금원판(11)이 뚜껑틀(40)의 잠금요부(41)에 진입하면서 걸림돌부(42)에 걸려 잠금이 이루어지게 되며, 이때 잠금원판(11)에는 요철부(12)와 경사면이 구성되어 있어 잠금쇠(10)를 시계방향으로 회전시키면 요철부(12)와 경사면에 의해 잠금이 더욱 견고히 이루어지게 된다는 구성이다.Therefore, the manhole cover locking device of the above configuration rotates the locking plate 11 formed in a plurality of places of the lid 20, the locking disc 11 is rotated, the locking disc 11 is the locking recess of the lid frame 40 ( 41 is locked to the locking portion 42 while entering the lock is made, the locking disc 11 is formed with an uneven portion 12 and the inclined surface, if the locking plate 10 is rotated in the clockwise direction uneven portion 12 ) And the inclined surface lock is more firmly made.

그러나 상기한 구성의 잠금장치는 다음과 같은 단점이 있다.However, the locking device of the above configuration has the following disadvantages.

즉 뚜껑(20)에 결합된 잠금쇠(10)의 잠금원반(11)이 뚜껑틀(40)의 걸림돌부(42)에 걸려 잠금이 이루어지게 되고, 잠금원반(11)의 요철부(12)와 경사면에 의해 잠금이 이루어지게 되나, 잠금쇠(10)를 구성하는 재질 자체가 탄성이 전혀 없는 주물로 구성되어 있어, 뚜껑(20)에 결합된 잠금쇠(10)가 상하방향으로 유격이 없는한 잠금자체에 어려움이 있고 또한 잠금이 이루어진다 하더라도, 뚜껑틀(40)의 걸림돌부(42)에는 잠금원판(11)의 요철부(12)와 걸림이 이루어질 수 없는 평면으로 구성되어 있어 잠금이 이루어진 상태에서 맨홀 위를 주행하는 차량에 의해 충격과 진동이 반복되면 경사지게 구성된 잠금원반(11)의 잠금이 풀리면서 걸림돌부(42)로부터 이탈되는 현상이 발생하게 되므로 잠금의 기능을 상실하면서 소음이 발생하게 될 뿐 아니라 심할 경우 뚜껑틀(40)로부터 뚜껑(20)이 이탈하면서 안전사고의 위험이 따르게 되는 문제가 있는 것이었다.That is, the locking disk 11 of the clamp 10 coupled to the lid 20 is caught by the locking protrusion 42 of the lid frame 40 to be locked, and the uneven portion 12 of the locking disk 11 is fixed. Locking is made by the inclined surface, but the material constituting the clamping pad 10 itself is composed of a cast-free elasticity, the locking clamp 10 coupled to the lid 20 as long as there is no play in the vertical direction lock itself Even if there is a difficulty in the locking and the locking is made, the locking portion 42 of the lid frame 40 is made of a flat surface that can not be engaged with the uneven portion 12 of the lock disc 11 manhole in the locked state When the shock and vibration are repeated by the vehicle traveling above, the locking disk 11, which is inclined, is released and the phenomenon of being separated from the locking portion 42 is generated. Therefore, noise is generated while losing the function of the locking. If severe, lid frame (40) At the lid (20) The departure was a problem that follow the risk of accidents.

또한 뚜껑(20)의 다수곳에 결합된 잠금쇠(10)의 결합부위를 통하여 빗물등이 누수되므로 뚜껑(20)과 뚜껑틀(40) 하단에 밀폐를 위한 밀폐링(30)과 밀폐턱(23), 밀폐돌기(43)와 같은 구성을 추가하여야 하므로 구성이 복잡해지게 되는 단점도 있다.In addition, since rainwater is leaked through the coupling portion of the clamp 10 coupled to a plurality of places of the lid 20, the sealing ring 30 and the sealing jaw 23 for sealing the bottom of the lid 20 and the lid frame 40 are closed. , Since the same configuration as the sealing protrusion 43 must be added, there is a disadvantage that the configuration becomes complicated.

특히 뚜껑(20)에 구성되는 잠금쇠(10)는, 뚜껑(20)에 조립식으로 결합하는 것이 아니라, 요철부(12)가 형성된 잠금원판(11)과, 축봉(13), 걸림테(14) 및 사각체결부(15)가 일체형으로 주물성형되게 먼저 제작하고, 상기 성형된 잠금쇠(10) 외면에 3mm정도의 두께로 주물사를 코팅한 다음 뚜껑(20) 성형시 금형틀에 고정시키고, 주물을 부어 뚜껑(20)의 축공(22)에 회전이 가능토록 일체형으로 구성되게 한 것이기 때문에 제작에 어려움이 있고, 취급 및 사용중 잠금쇠(10)가 부분적으로 파손될 경우 교체할 수 있는 수단이 없는 관계로 뚜껑(20) 전체를 교환하여야 하는 폐단이 있고, 잠금쇠(10)의 축공(13)이 끼워진 축공(22) 상단부가 외부로 노출되어 있어 사용중 축공(22) 부분에 이물질이 유입되고, 이러한 경우 뚜껑(20)을 개방시키고자 할 때마다 작업자가 이물질을 일일히 제거하여야 하는 등의 불편함이 있는것이었다.In particular, the clasp 10 constituted by the lid 20 is not coupled to the lid 20 in a prefabricated manner, but the locking disc 11 having the uneven portion 12 formed thereon, the shaft rod 13, and the hook frame 14. And first, the square fastening part 15 is integrally formed into a cast molding, and then the casting sand is coated with a thickness of about 3 mm on the outer surface of the formed clamp 10, and then fixed to the mold frame when forming the lid 20, the casting It is difficult to manufacture because it is made to be integrally formed so that the shaft hole 22 of the pour lid 20 can be rotated, and there is no replaceable means when the clamp 10 is partially damaged during handling and use. (20) There is a closed end that needs to be replaced, and the upper end of the shaft hole 22 into which the shaft hole 13 of the clamping hole 10 is fitted is exposed to the outside, so that foreign matter enters the shaft hole 22 during use, and in this case, the lid ( 20) Whenever you want to open the That the discomfort was such as to be removed.
