본 고안은 후면 투사방식을 위한 조립식 멀티스크린장치의 개량에 관한 것이다.The present invention relates to an improvement of the assembled multi-screen device for the rear projection method.

종래 컴퓨터나 프로젝터투사기의 후면투사방식에 있어서 화면을 크게 하려면 스크린을 크게하거나 스크린과 투사기 사이에 상당한 거리를 두어야 하나 좁은 공간에서 이것이 이루어지지 못하면 화면이 선명하지 못하므로 이것을 시정하기 위하여 프로제터화면을 원하는 크기로 분활하고 분활된 단위화면에 각각 독립된 투사기를 통하여 투사하면 되나 이경우에는 투사기 상호간에 빛의 간섭이 심하고 분활된 스크린과 스크린사이의 둘레의 테두리로 인하여 화면의 연결이 잘 안되고 또한 각 단위 스크린을 교체하거나 화면을 넓히기 위하여 단위스크린을 좌우 상하로 증설 조립하기가 용이하지 아니하므로 이와같은 문제점을 해결하기 위하여 스크린간에 빛차단판을 설하고 스크린 사이를 1/2인치정도로 최소화하여 조립식으로 한 본 고안자가 고안하여 실용신안등록 출원 제91-15808호로 출원한 것도 있으나 이 경우에도 화면의 연결을 만족하게 해결하지 못하였다. 본 고안은 이와같은 문제점을 해결하기 위하여 스크린과 스크린사이에 T형 투명 아크릴고정구를 끼워서 화면을 연결한 것으로서 이하 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.In the rear projection method of a conventional computer or projector projector, to enlarge the screen, the screen should be enlarged or a considerable distance between the screen and the projector should be provided. However, if this cannot be done in a narrow space, the screen will not be clear. The projector can be projected through the independent projectors on the divided and divided unit screens in the desired size, but in this case, the screen is not connected well due to the interference of light between the projectors and the border around the divided screen and the unit screen. It is not easy to assemble the unit screens left and right and up and down in order to replace the screen or widen the screen. Deviser devises It was open utility model application No. 91-15808 filed arcs, but did not resolve satisfactorily the connection of the screen in this case. The present invention is connected to the screen by inserting a T-type transparent acrylic fixture between the screen and the screen to solve the problems as described below in detail the present invention by the accompanying drawings.

본 고안은 4각 스크린고정칸(1')이 상하좌우로 다수 병설된 후면투사조립식 멀티스크린장치(1)에 있어서 칸막이벽(3)의 전방단부(3')에 당접되게 스크린(2)과 스크린(2)틈사이로 T형투명아크릴테(4)를 끼어넣고 양측에서 고정판(7)(8)을 대고 보울트(5)(5')와 넛트(6)(6')로 체결 고정하고, 스크린(2)과 바깥벽(9)틈사이로 T형 알미늄앵글 (10)을 끼워놓고 고정판(11)을 나사(12)(12')로 나착 고정하는 후면투사조립식 멀티스크린 장치이다.The present invention is a rear projection assembly type multi-screen device (1) in which a quadrilateral screen fixing compartment (1 ') is provided in a plurality of up, down, left and right sides in contact with the front end (3') of the partition wall (3) and Insert T-shaped transparent acryl frame (4) between the screen (2) gaps, and fasten and fix with bolts (5) (5 ') and nuts (6) (6') with fixing plates (7) (8) on both sides. It is a rear projection assembly type multi-screen device that sandwiches the T-shaped aluminum angle 10 between the screen 2 and the outer wall 9, and fixes the fixing plate 11 by screws 12 and 12 '.

본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention is as follows.

본 고안의 멀티스크린장치인 T형 투명아크릴테 (4)를 스크린(2) 사이에 끼워서 그 선단이 칸막이벽(3)의 전방단부(3')에 당접되게 하여 양단부에 걸쳐서 고정판(7) (8)를 좌우양쪽에 대고 보울트(5)(5')와 넛트(6)(6')로 체결하여 고정하였으므로 T형 투명아크릴테(4)은 칸막이벽(3)에 안정하게 결착하고 T형 투명아크릴테(4)은 투명이므로 스크린(2)과 스크린(2)사이에 테두리형상이 적게 나타나므로 해서 화면의 연결을 크게 방해하지 아니한다.The T-shaped transparent acryl frame 4, which is a multi-screen device of the present invention, is sandwiched between the screens 2 so that its tip abuts against the front end 3 'of the partition wall 3, and thus the fixing plate 7 ( 8) Put the bolts (5) (5 ') and the nuts (6) (6') on both sides to fix the T-type transparent acryl (4) to the partition wall (3). Since the transparent acryl frame 4 is transparent, there is less rim shape between the screen 2 and the screen 2, so that the connection of the screen is not significantly disturbed.

또한 제1도와 같이 정부(4')가 반구상으로 형성되면 더욱 효과가 크다.In addition, if the government (4 ') is formed in a hemispherical shape as shown in FIG.

한편 고정판(7)(8)의 외단에 절곡부(7')(8')를 형성하면 스크린(4)을 안밖에 협지하여 잡아주므로 견고하게 조립된다.On the other hand, when the bent portions 7 'and 8' are formed at the outer ends of the fixed plates 7 and 8, the screen 4 is held by the outside and is firmly assembled.

한편 스크린(4)과 바깥벽(9)사이에 끼어서 T형 알미늄앵글(10)은 고정판(11)을 대고 나사(12)(12')로 바깥벽(9)에 나착 고정하면 된다.Meanwhile, the T-shaped aluminum angle 10 is sandwiched between the screen 4 and the outer wall 9 by attaching the fixing plate 11 to the outer wall 9 with screws 12 and 12 '.

또한 4각형 스크린고정칸(1')은 칸막이벽(3)으로 둘러 싸여서 투사기 상호간의 빛의 간섭을 저지하게 되므로 화면이 선명하게 비치게된다. 이와같이 본 고안은 간단한 구조로서 스크린을 견고하게 조립할수 있고 투사기 상호간에 빛의 간섭이 없어서 화면이 선명하고 스크린과 스크린 사이에 테두리현상이 나타나지 아니 하므로 화면을 넓게 연결할 수 있는 매우 유용한 고안이다.In addition, the quadrilateral screen fixing compartment (1 ') is surrounded by the partition wall (3) to block the interference of light between the projectors, so that the screen is clearly reflected. In this way, the present invention is a simple structure, the screen can be firmly assembled and there is no interference of light between the projectors so that the screen is clear and the screen does not appear borders between the screen is very useful design that can be connected widely.
