코일스프링 경첩의 탄발력 조절장치{ELASTICITY CONTROL DEVICE FOR SPRING HINGE}Resilience control device of coil spring hinge {ELASTICITY CONTROL DEVICE FOR SPRING HINGE}

본 발명은 코일스프링 경첩의 탄발력 조절장치에 관한 것이다. 좀더 자세하게는 연결편에 단일체로된 관형 동체의 상, 하단에는 타측연결편에 부착시킨 회전관을 설치하고 하부회전관에 지지축을 삽입시켜 관형 동체 하단에 나사물림으로 고정시켜 관형 동체 내부에 설치된 코일스프링의 하단을 고정시키고 상부 회전관에는 중앙부에 확개부를 형성한 회전축을 삽입시켜 확개부의 단턱에 코일스프링의 상단을 고정시키며, 회전축의 중앙 확개부 상면에 방사상으로 래칫을 형성하여 회전관에 삽입 고정시킨 지지링의 일측에 설치한 출몰 래칫폴이 맏물리게 하여 코일스프링을 감아 탄발력을 강화 시키거나 코일스프링을 풀어 주어 탄발력을 약화시킬 수 있게 한 코일스프링의 탄발력 조절장치에 관한 것이다.The present invention relates to an elastic force adjusting device of the coil spring hinge. More specifically, the upper and lower parts of the tubular fuselage on the connecting piece are installed at the lower part of the tubular body, and the support shaft is inserted into the lower part of the tubular fuselage. The lower end is fixed, and the upper rotating tube is inserted with a rotating shaft having an enlarged portion at the center to fix the upper end of the coil spring at the stepped portion of the enlarged portion, and the ratchet is formed radially on the upper surface of the central extended portion of the rotating shaft to be inserted into the rotating tube. The present invention relates to a coil spring elasticity adjusting device which allows the spring ratchet pole installed on one side of the ring to be wound up to reinforce the elastic force by winding the coil spring or to release the coil spring to weaken the elastic force.

종래의 코일스프링 경첩은 일정한 탄발력을 유지시킨 상태에서 조립하였기 때문에 조립이 어려운 문제점이 있었으며, 문과 문틀 사이에 강한 경첩을 설치하였을 경우에는 문을 열거나 닫을 경우에 탄발력이 강하여 문이 빠른 속도로 닫히게 되므로 문이 탄발력에 의하여 파손되는 경우가 허다 하였으며, 문틀과 문틀 사이에 손이 끼어 있을 경우에는 부상을 입게 되는 예가 허다 하였다. 따라서 코일스프링의 탄발력을 조절하여야 하는데 코일스프링의 탄발력을 조절하기에는 커다란 문제점이 있었다.Conventional coil spring hinges are difficult to assemble because they are assembled in a state of maintaining a constant elasticity, and when a strong hinge is installed between the door and the door frame, when the door is opened or closed, the door is fast due to strong elasticity Since the door is closed due to the elastic force, it is frequently used. When the hand is caught between the door frame and the door frame, there are many cases of injury. Therefore, the elastic force of the coil spring should be adjusted, but there was a big problem in controlling the elastic force of the coil spring.

본 발명은 이와 같은 문제점을 해결하기 위하여 연결편에 단일체로된 관형 동체의 상, 하단에는 타측연결편에 부착시킨 회전관 설치하고 하부회전관에 지지축을 삽입시켜 관형 동체 하단에 나사물림으로 고정시켜 관형 동체 내부에 설치된 코일스프링의 하단을 고정시키고 상부 회전관에는 중앙부에 확개부를 형성한 회전축을 삽입시켜 확개부의 단턱에 코일스프링의 상단을 고정시키며, 확개부의 상면에는 방사상으로 래칫을 형성하고, 회전축의 중앙 확개부 상부에 형성된 회전축에 지지링을 삽입시켜 회전관에 보울트로 고정시키고, 지지링의 일측에 형성된 삽입홈에 코일스프링으로 탄지시킨 출몰 래칫폴을 설치하여 확개부에 형성된 방사상의 래칫과 맏물리게 하고,래칫폴을 상부로 가는 봉으로 연장시켜 지지링의 상부로 노출시킨 단부에 너트를 나사물림시키고 너트의 하부에는 지지링의 양측양측에 형성된 호형 지지편에 핀으로 연결시킨 링형 해지구의 절결단부를 접지시키고 상부 회전축의 단부에는 공구 삽입구가 형성된 너트를 나사물림 시키므로써 공구를 이용하여 너트를 우회전시키면 확개부 상면에 형성된 래칫이 래칫폴을 밀어 올리면서 회전축과 같이 회전하면서 스프링을 감기게 하고, 링형 해지구의 일측을 하강시켜 래칫폴을 들어 올리게 되면 래칫과 래칫폴이 해지되므로 코잉스프링의 탄발력에 의하여 회전축이 역회전 하면서 코일스프링의 탄발력은 약하게 플리게 하기 위한 것이다.The present invention is installed in the upper and lower parts of the tubular body of the tubular fuselage to the connecting piece in order to solve this problem, and the support shaft is inserted into the lower rotary tube to be fixed to the lower end of the tubular fuselage by screwing the tubular fuselage Fixing the lower end of the coil spring installed inside, and inserting the rotary shaft formed in the center of the upper rotary tube to secure the upper end of the coil spring on the stepped portion of the expansion, and forming a ratchet radially on the upper surface of the extension, the center of the rotating shaft Insert the support ring into the rotary shaft formed on the upper part of the extension part and fix it with a bolt on the rotary tube, and install the outgoing ratchet pole held by the coil spring in the insertion groove formed on one side of the support ring so that the ratchet with the radial ratchet formed in the extension part And nut at the end exposed to the top of the support ring by extending the ratchet pole Screw the nut and ground the cutout of the ring-shaped release hole connected with pins to the arc-shaped support pieces formed on both sides of the support ring at the lower part of the nut, and screwing the nut with the tool insertion hole at the end of the upper rotating shaft. When the nut is turned to the right, the ratchet formed on the upper part of the extension part pushes up the ratchet pole and rotates together with the rotating shaft to wind the spring, and when the ratchet pole is lifted by lowering one side of the ring-shaped release hole, the ratchet and ratchet pole are released. The elasticity of the coil spring is weakened while the rotating shaft reverses due to the elasticity of the coil.

It was allowed to rotate safely. The coil spring 30 is wound or unrolled according to the rotational direction of the rotation shaft 21 by fixing the upper end of the coil spring 30 to the stepped portion of the extension portion 21a formed on the rotation shaft 21. In addition, the ratchet 23 is radially formed on the upper surface of the extension portion 21a, and the support ring 40 is inserted into the rotation shaft 21b formed at the upper portion of the central extension portion 21a of the rotation shaft 21 to rotate the rotary tube ( 12) is fixed to the bolt 41 to be rotated along with the rotary tube 12, and one side of the support ring 40 is supported by the coil spring 31 in the insertion groove 40b in which the through hole 40a is formed.

Ground (51). Therefore, when one side of the ring-shaped release sphere 50 is pressed, the ratchet pawl 24 is released from the ratchet as it enters into the insertion groove 40a formed in the support 40 while compressing the coil spring 31. Due to the resilience of 30, the revolving shafts 21 and 21b are reversely rotated so that the resilience of the coil spring 30 is weakly released. And when the hand holding the release sphere 50 is released, the ratchet pole 24 is first caught by the ratchet by the elastic force of the coil spring 31, and the tool insertion groove 52a is formed at the end of the upper rotating shaft 21b. By inserting the tool into the tool insertion groove 52a by fastening the formed nut 52 by screwing, when the nut 52 is rotated to the right, the ratchet 23 formed on the upper surface of the enlarged portion 21a receives the ratchet pole 24. The coil spring 30 is wound while being rotated together with the rotary shafts 21 and 21a while being pushed up, and the coiled coil coil 30 is wound up by the ratchet 23 until the ratchet poles 24 are lifted. Since the elastic force of the coil spring 30 can be freely adjusted, the hinge is minimized during use, and when the hinge is installed between the door and the door frame, the coil spring 30 can be installed with little elastic force. Hinges are easy to install.
