본 고안은 방송용 카메라를 EFP시스템으로 사용할때 카메라와 신호보상장치를 연결해 주는 케이블을 감아주기 위하여 사용되는 드럼에 관한 것으로서 케이블을 일정한 길이만큼 인출한 후 더이상 드럼이 회전하여 케이블이 풀리는 것을 방지하기 위한 브레이크 장치를 보다 간단하게 개량한 것이다.The present invention relates to a drum used to wind a cable connecting a camera and a signal compensator when the broadcasting camera is used as an EFP system. After the cable is drawn out to a certain length, the drum is no longer rotated to prevent the cable from being released. It is a simpler improvement of the brake system.
종래 케이블을 감는 드럼에 사용되어온 브레이크장치로서는 마찰력을 이용하여 드럼의 회전력을 제어하는 수단을 사용하였으나 이러한 장치는 브레이크 작용을 확실하게 제어할 수 없는 단점이 있으며 이와 같은 점을 해소하기 위하여 라쳇휄(Ratchet Wheel)을 사용하는 방법이 강구되었었다.Conventionally, as a brake device used in a drum for winding a cable, a means of controlling the rotational force of the drum by using a friction force is used. However, such a device has a disadvantage in that the brake action cannot be reliably controlled. Ratchet Wheels were used.
그러나 라쳇휄을 사용할시에는 케이블을 감을시에 라쳇휄과 라쳇기어와의 마찰소음이 발생하는 문제점이 있었다.However, when the ratchet is used, there is a problem that friction noise between ratchet and ratchet gear occurs when the cable is wound.
본고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로서 드럼의 회전이 불필요할 경우 간단한 장치에 의해 확실하게 드럼의 회전을 제어할 수 있으며 브레이크의 해제도 용이하게 실시할 수 있도록 함을 본 고안의 목적으로 한다.The present invention was devised to solve the above problems, and when the rotation of the drum is unnecessary, it is possible to reliably control the rotation of the drum by a simple device and to easily release the brake. The purpose.
상기와 같은 목적을 달성하기 위한 바람직한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings a preferred embodiment for achieving the above object as follows.
우선 첨부된 도면에 의거 본 고안의 구성을 설명하면, 케이블을 드럼(1)과 트러스(2) 사이에 장착되는 브레이트 장치는 감는 드럼(1)의 외주면상에 일정간격(A)을 가지며 양측면이 절곡되어 돌출부(3')를 갖는 안내판(3)을 설치하고 트러스(2)의 내측에는 상측의 힌지축(4)에 비틀림 스프링(5)을 탄지되며, 안내홈(7)을 가지는 제동판(8)을 단부(8')가 드럼(1) 외주면에 설치된 안내판(3) 사이에서 잠금 및 해제되도록하며, 상기 제동판(8)을 제어하는 브레이크축(6)은 트러스(2)내면의 스토파링(9)에 지지되어 핸들(10)로 작동시킬수 있도록 하여서 된 것으로서, 이와 같이 구성된 본 고안의 작용효과는 우선 케이블이 감긴 드럼에서 케이블을 풀고자 할 경우에는 제 3 도에 가상선으로 도시된 바와 같이 브레이크축(6)의 단부(6')가 제동판(8)의 안내홈(7)의 하측면을 지지하고 있으므로 제동판의 단부(8')가 드럼(1)에 설치된 안내판(3)으로 부터 이탈된 상태이므로 드럼(1)은 자유스럽게 회전할 수 있는 상태가 된다.Referring to the configuration of the present invention based on the accompanying drawings, the brate device for mounting the cable between the drum (1) and the truss (2) has a certain distance (A) on the outer peripheral surface of the winding drum (1) and both sides The guide plate 3 which is bent and provided with the protrusion part 3 'is installed, and the torsion spring 5 is supported by the upper hinge shaft 4 inside the truss 2, and the braking plate having the guide groove 7 8) the end 8 'is locked and released between the guide plates 3 provided on the outer peripheral surface of the drum 1, and the brake shaft 6 controlling the braking plate 8 is a stow on the inner surface of the truss 2. It is to be supported by the paring (9) to be operated by the handle 10, the effect of the present invention is configured as shown in Figure 3 as a virtual line in the case of first unwinding the cable from the cable wound drum The end 6 'of the brake shaft 6 supports the lower side of the guide groove 7 of the brake plate 8 as shown. Because so that the exit from the end portion (8 ') a guide plate (3) installed on the drum 1 of the copper state drum 1 is in a state capable of rotating freely.
이러한 상태에서 드럼(1)에 감긴 케이블을 필요한 길이만큼 풀어낸후 드럼(1)이 더이상 회전하지 못하도록 제동을 가하고자 할 경우에는 제 3 도에 실선으로 도시된 바와 같이 핸들(10)을 180°회전시키면 브레이크축(6)이 같이 회전하면서 브레이크축(6)의 단부(6')가 안내홈(7)에 안내되어 상측으로 옮겨가게 되므로 힌지축(4)에서 가까운 거리를 압지하게 되어 제동판(8)은 비틀림 스프링(5)의 탄력에 의해 외측으로 벌어지게 되는데 이때 제동판(8)의 단부(8')가 드럼(1)의 외측에 설치된 안내판(3)사이에서 벌어지므로 드럼(1)의 안내판(3)의 돌출부(3')가 상기 제동판단부(8')에 걸리게 되므로 드럼(1)의 회전하지 못하게 된다. 또한 제동판(8)의 단부(8')가 안내판(3)과 일치된 경우에는 돌출부(3')가 경사져 있으므로 제동판(8)의 단부(8')가 경사면에 안내되어져 제동판(8)이 트러스(2)방향으로 눌렸다가 비틀림스프링(5)의 복원력에 의하여 원위치 하면서 제동판(8)의 단부(8')가 상기 안내판(3) 사이에서 돌출부(3')에 걸리게 되므로 드럼(1)은 회전하지 못하게 된다. 즉 제동이 걸리게 되는 것이다.In this state, when the cable wound on the drum 1 is loosened to the required length, and the brake is to be applied to prevent the drum 1 from rotating any further, the handle 10 is rotated 180 ° as shown by the solid line in FIG. When the brake shaft 6 rotates together, the end portion 6 'of the brake shaft 6 is guided to the guide groove 7 and moved upward, thereby holding a close distance from the hinge shaft 4 to the brake plate ( 8) is opened to the outside by the elasticity of the torsion spring (5) in which the end (8 ') of the brake plate (8) is opened between the guide plate (3) provided on the outside of the drum (1) Since the protrusion 3 'of the guide plate 3 is caught by the braking end 8', the drum 1 cannot be rotated. In addition, when the end 8 'of the braking plate 8 coincides with the guide plate 3, since the protrusion 3' is inclined, the end 8 'of the braking plate 8 is guided to the inclined surface and the braking plate 8 ) Is pressed in the direction of the truss (2) and the end 8 'of the braking plate 8 is caught by the projection 3' between the guide plates 3 while being retracted by the restoring force of the torsion spring 5 (1) will not rotate. That is, braking takes place.
이와 같은 상태에서 케이블을 드럼에 감거나 또는 더인출 하기 위하여 드럼(1)을 회전시키고자 할 경우에는 핸들(10) 상기와 반대방향으로 180° 회전시키면 상기 제어동작의 역순으로 브레이크축(6)의 단부(6')가 밑으로 회전하면서 제동판(8)을 트러스(2) 방향으로 밀게되므로 제동판(8)은 안내판(3) 사이에서 돌출부(3')를 벗어나 이탈되므로 드럼을 드럼은 자유상태가 되므로 자유로이 회전시킬수 있게 되는 것으로 드럼(1)을 회전시켜 케이블을 감거나 풀어줄수 있게된다.In such a state, when the drum 1 is to be rotated in order to wind the cable to the drum or draw further, the handle shaft 10 is rotated 180 ° in the opposite direction to the brake shaft 6 in the reverse order of the control operation. The drum 6 is displaced out of the projection 3 'between the guide plates 3 because the end plate 6' of the brake plate 8 is pushed in the direction of the truss 2 while rotating downward. Since the free state can be freely rotated by rotating the drum (1) it is possible to wind or unwind the cable.
이상 설명한 바와 같이 본 고안에 의하면 간단한 장치에 의하여 불필요한 소음을 발생하지 않고 드럼의 회전을 정확하게 멈춤 또는 해제할 수 있게된다.As described above, according to the present invention, the rotation of the drum can be accurately stopped or released by a simple device without generating unnecessary noise.
