본 고안은 1면 반사 투과형 프로젝션 테레비젼(Projection TV)에 있어서 렌즈와 투사관으로 구성되는 투사부의 각도를 조절하여 스크린의 중심에 화면의 중심이 투사될 수 있게 하는 투사각 조정장치에 대한 것이다.The present invention is directed to a projection angle adjusting device that allows the center of the screen to be projected to the center of the screen by adjusting the angle of the projection unit consisting of a lens and a projection tube in a one-side reflection transmission type projection TV.

종래의 프로젝션 테레비젼은 편향 회로 및 편향 마그네트를 이용하여 화면의 중심이 스크린의 중심에 맞도록 하는 장치를 사용하였으나 이러한 전기적 조절방법으로는 투사각을 조정할 수 있는 가변의 범위가 한정되어 있기 때문에 그 범위를 벗어난 상에 대하여는 조정이 불가능하였다.Conventional projection TVs use a device that allows the center of the screen to be aligned with the center of the screen by using a deflection circuit and a deflection magnet. However, the electric control method has a limited range of adjustable projection angles. No adjustment was possible for the out of phase image.

즉, 프로젝션 테레비젼을 조립 완료한 후 상의 조정을 하는 과정에서 조립의 오차 및 부품자체의 오차등에 의해 화면의 중심이 스크린의 중심에 투사되지 않기 때문에 통상적으로 투사관에 부착된 센터링 마그네트로이를 전기적으로 조정하고 있으나, 투사거리는 긴 렌즈를 이용할 때 미세한 각의 오차로 인해 중심거리의 편차가 크게 발생하기 때문에 전기적인 가변방법으로는 효과적으로 조정할 수 없었다.That is, since the center of the screen is not projected to the center of the screen due to the assembly error and the error of the parts themselves during the adjustment of the image after the projection TV is assembled, the centering magnet Roy attached to the projection tube is normally electrically However, the projection distance could not be effectively adjusted by the electric variable method because a large deviation of the center distance occurs due to a slight angle error when using a long lens.

또한 이런점을 해소하기 위해 반사경자체 또는 반사경이 부착된 백캐비네트를 움직여 이를 조정하는 방법도 있었으나 이 경우에는 중량이나 부피가 큰 백캐비네트를 움직이기 위해서는 많은 힘이들며 번거롭고 불폄함은 물론 정확한 조정이 되지 못하였으며 또 반사경 자체만을 움직이는 벙법도 있으나 이는 반사경의 고정이 불안정하게 되기 때문에 반사경이 쉬 파손되는 등의 폐단이 있었다.In order to solve this problem, there was a method of adjusting the reflector itself or a back cabinet attached with a reflector. However, in this case, moving a heavy or bulky back cabinet requires a lot of force, and is cumbersome and troublesome. There was no adjustment and there was a way to move only the reflector itself.

본 고안은 이와 같은 점들을 해결하기 위해 투사관과 렌즈를 착설한 고정대를 워엄과 워엄기어를 이용하여 회동자재토록 한 것으로 이런 방법으로 조정할 경우 화면의 중심이 스크린의 중심에 정확하게 투사됨은 물론 조정작업이 매우 간편 용이하게 되는 것으로 첨부도면에 의거 상술하면 다음과 같다.In order to solve these problems, the present invention uses a worm and a worm gear to rotate the mounting bracket on which the projection tube and the lens are installed. In this way, the center of the screen is accurately projected to the center of the screen. This will be very easy to be described in detail based on the accompanying drawings as follows.

렌즈(2)와 투사관(3)을 고정부착한 고정대(1)를 양측의 지지축(4)으로 고정판 (5)(5')에 회동자재토록 설치하고, 고정대(1)의 일측 후면에는 회전고정판(6)을 부착하여 고정판(5)에 뚫어진 장공(7)을 통해 보울트(8)와 나비너트(9)를 고정토록 하고, 전면에는 워엄기어(10)를 부착하여 고정판(5)에 뚫어진 회동장공(11)을 통해 외측으로 노출시켜 그 측방에 회전되게 착설한 워엄(12)과 치합시키고 이 워엄(12)의 상단에는 조정홈(13)을 형성하여서 된 것이다.A fixing stand (1) having the lens (2) and the projection tube (3) fixed thereto is installed on the fixing plates (5) (5 ') by the support shafts (4) on both sides so as to be rotatable. The rotating fixing plate (6) is attached to fix the bolt (8) and the butterfly nut (9) through the long hole (7) drilled in the fixing plate (5), and the worm gear (10) is attached to the fixing plate (5) on the front side. Exposed to the outside through the piercing turning hole 11 is engaged with the worm 12 installed so as to rotate on the side, and the upper end of the worm 12 is to form an adjustment groove 13.

이와 같이 구성된 본 고안은 작용상태를 설명하면 다음과 같다.The present invention configured as described above is as follows.

화면의 투사각을 조정할 때에는 나비너트(9)를 적당히 풀어서 회전고정판(6)에 부착된 보울트(8)가 장공(7)을 따라 이동될 수 있도록한 다음, 워엄(12)의 상단에 형성된 조정홈(13)에 드라이버등을 끼워 워엄(12)을 필요한 방향으로 회전시키면 이 워엄(12)에 치합된 워엄기어(10)가 회동되기 때문에 이 워엄기어(10)의 회동으로 고정대(1)가 양측의 지지축(4)에 의해 고정판(5)(5')사이에는 필요한 방향으로 회동되어 렌즈(2)의 방향을 바꿔주게 되는 것이며, 이렇게 하여 렌즈(2)의 방향조정이 완료된면 이후 나비너트(9)를 조여서 회전고정판(6)을 고정시켜주면 이에의해 고정대(1)가 조정된 상태에서 정지되어 움직이지 않게 되는 것이다.When adjusting the projection angle of the screen, loosen the butterfly nut (9) properly so that the bolt (8) attached to the rotation fixing plate (6) can be moved along the long hole (7), and then the adjustment groove formed at the top of the worm (12) When the worm 12 is rotated in the required direction by inserting a screwdriver or the like in (13), the worm gear 10 engaged with the worm 12 is rotated. By the support shaft 4 of the fixed plate (5) (5 ') is rotated in the required direction to change the direction of the lens (2), in this way, after the direction of the lens 2 is completed, the butterfly nut Tighten (9) to fix the rotation fixing plate (6) by this stops the fixed stand (1) in the adjusted state will not move.

이와 같이 작동되는 본 고안은 워엄을 회전시켜주는 것만으로 화면의 중심이 스크린의 중심에 정확히 투사될 수 있도록 조정할 수 있으므로 조정방법이 매우 간편 용이하고, 또 그 조정범위가 넓게 되어 항상 선명한 화상을 얻을 수 있게 되며, 그 구조가 간단하고 고장의 염려가 없는 등 매우 효과적인 고안이다.The present invention, which operates in this way, can be adjusted so that the center of the screen can be accurately projected to the center of the screen simply by rotating the worm, so the adjustment method is very simple and easy, and the range of adjustment is wide so that a clear image is always obtained. It is possible to design, the structure is simple, and there is no fear of failure, it is a very effective design.
