본 고안은 후면투사 방식을 위한 조립식 멀티스크린을 전면에서 착탈하는 고정장치에 관한것이다.The present invention relates to a fixing device for attaching and detaching a prefabricated multi-screen for the rear projection type from the front.

종래의 후면투사 방식을 위한 조립식 멀티스크린 장치는 통상적으로 화면을 원하는 크기로 분할하고, 각분할된 단위화면에 독립된 투사기를 통하여 투사하는 구성이나, 이 경우에 각 분할된 단위스크린의 가장자리에 둘린 테두리가 장애가 되어 영상이 끊어져 화면의 연결이 잘 안되고, 또한 각 단위 스크린을 교환하거나 화면을 확대하기 위하여 단위스크린 옆으로나 위로 증설하지 못하였으므로, 이와같은 문제점을 해고하기 위한 것으로 본 출원인이 고안한 실용신안등록출원 91-15808호도 있으나, 이 경우에는 구조상 스크린을 1/2인치 정도의 알루미늄판체로된 테두리로 둘러 씌워야 되므로 둘린 테두리의 폭이 비교적 넓어서 영상의 단절을 최소화하지는 못하였다.In the conventional multi-projection apparatus for rear projection, a screen is usually divided into a desired size and projected through an independent projector on each divided unit screen, or in this case, an edge surrounded by an edge of each divided unit screen. The screen breaks down due to an obstacle, and the screen is not connected well. Also, the utility model devised by the present applicant for the purpose of dismissing such a problem has not been expanded to the side or up of the unit screen in order to replace each unit screen or enlarge the screen. There is also a registration application 91-15808, but in this case, because the screen should be surrounded by a frame made of aluminum plate of about 1/2 inch, the width of the frame was relatively wide, which did not minimize the disconnection of the image.

본 고안은 이와같은 문제점을 해결하기 위하여 스크린의 가장자리를 둘러싼 테두리의 폭을 최소화하여 화면의 연결이 잘되고, 각 단위 멀티스크린이 전면에서 착탈 자재하게 조립되게 하여 증설과 감축이 용이하고, 외관도 미려하게한 것으로서, 이하 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.In order to solve such problems, the present invention minimizes the width of the edges surrounding the edges of the screen so that the screens are connected well, and each unit multi-screen is detachably assembled from the front, so that the expansion and reduction is easy and the appearance is beautiful. As described above, the present invention is described in detail by the accompanying drawings as follows.

본 고안의 구성은 4각형 스크린고정칸(1')이 상하좌우로 병설된 후면투사 조립식 멀티스크린 장치에 있어서, 상자본체(1)의 좌우측판(2)(2') 및 상하판(3)(3')과 종격판(6) 및 횡격판(6')(6")의 전방 단연에 돌편(7)을 다수 경사지게 돌설하여 요철면을 형성하고, 4방 가장자리에 돌편(8)이 다수 경사지게 돌설하여 요철면을 형성하고, 4방가장자리에 돌편(8)이 다수 형성된 스크린(9)을 개재하여 스크린고정프레임(10)(10')(10")(10'")으로 고정하되, 스크린고정프레임(10)(10')(10")(10'")의 후방 단연에 4각형틈(11')이 안깊이 연장 요입된 경사진 요결부(11)를 스크린(9)의 돌편(8)에 대응되게 형성하여 스크린(9)의 돌편(8)을 스크린 고정프레임(10)(10')(10")(10' ")의 4각형 틈(11')에 괘지하고, 고정구(12)로 체결 고정하여 전면에서 착탈되게 한 후면 투사 조립식 멀티스크린 고정장치이다.The structure of the present invention is a rear projection assembled multi-screen device in which a quadrangular screen fixing compartment (1 ') is installed in a vertical, horizontal, horizontal direction, left and right side plates (2) (2') and upper and lower plates (3) of the box body (1). (3 ') and a plurality of stone pieces (7) inclined at the front edge of the longitudinal plate (6) and the transverse plate (6') (6 ") to form a concave-convex surface, and a large number of stone pieces (8) at four edges The inclined protrusion is formed to form an uneven surface, and is fixed to the screen fixing frames 10, 10 ', 10 ", 10'" via a screen 9 having a plurality of stone pieces 8 formed at four edges. Inclined concave convex part 11 in which the quadrangular gap 11 'extends deeply into the rear edge of the screen fixing frames 10, 10', 10 " and 10 '" Formed to correspond to (8) so that the projections 8 of the screen 9 hang on the quadrangular gaps 11 'of the screen fixing frames 10, 10', 10 " and 10 '" Rear projection prefabricated multi-screen fixture that is secured with (12) and detached from the front The.

또한, 본 고안에 있어서는 종격판(6)과 횡격판(6')(6")의 전방 단연의 돌편(7)과 이것에 결착되는 스크린 고정프레임(10)(10')(10")(10' ")의 요결부(11)를 스크린(9)의 돌편(8)의 두배로 형성하여, 인접된 칸(1')에 스크린(9)의 돌편(8)이 교호로 괘지할 수도 있다.Further, in the present invention, the projection 7 of the front edge of the longitudinal plate 6 and the transverse plate 6 ', 6 "and the screen fixing frames 10, 10', 10" which are bound to this ( The concave portion 11 of 10 '"may be formed twice as large as the projection piece 8 of the screen 9, and the projection piece 8 of the screen 9 may alternately hang in the adjacent compartment 1'. .

미 설명부호5는 결착금구이다.Reference numeral 5 is a fastener.

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

본 고안의 상자본체(1)는 좌우측판(2)(2'), 상하판(3)(3') 및 종횡격판(6)(6')으로 조립하여 스크린고정칸(1')을 병설하고, 각 칸(1')을 둘러싼 판체의 전방 단연에 경사진 돌편(7)을 다수 형성하고, 돌편(7)에 대향되게 안쪽 단연에 4각형 틈(11')이 안깊이 요입 연장된 경사진 요결부(11)가 다수 형성된 스크린 고정프레임(6)(6')(6")로 조립하여 스크린고정칸(1')을 병설하고, 각 칸(1')을 둘러싼 판체의 전방 단연에 경사진 돌편(7)을 다수 형성하고, 돌편(7)에 대향되게 안쪽 단연에 4각형 틈(11')이 안 깊이 요입 연장된 경사진 요결부(11)가 다수 형성된 스크린 고정프레임(10)(10')(10" )(10'")을 가장자리에 돌편(8)이 형성된 스크린(9)을 개재 하여, 측판 전방 단연의 돌편(7)에 감착한다. 이때 스크린의 돌편(8)은 스크린 고정프레임(10)(10')(10")(10' ")의 후방에 안깊이 요결된 4각형 틈(11')에 괘지되고,스크린(9)은스크린고정프레임(10)(10')(10")(10'")의 요결부(11)사이에 얹히어져 지지되고, 경사진 요결부에 감합되므로 고정구(12)로 스크린 고정프레임(10)(10')(10")(10' ")을 각 측판에 체결 고정하면, 스크린(9)은 스크린 고정프레임(10)(10')(10")(10' ")위에 놓여 안전하게 고정하게 되는데, 종격판(6)과 횡격판(6')(6") 전방의 돌편(7)과 이것과 괘지되는 스크린 고정프레임(10)(10')(10")(10' ")의 요결부(11)는 인접 칸(1')에 착설하는 스크린(9)을 공동으로 괘지 고정하여야 되므로 스크린(9)의 돌편(7)의 두배로 요결부(11)를 형성하여, 옆 칸(1')의 스크린(9)의 돌편(7)이 교호로 괘지되게 하면된다. 한편, 스크린 고정프레임(10)(10')(10")(10' ")은 종횡으로 괘지되어 있어서 스크린(9)의 하중에도 불구하고 안전하게 고정된다. 이와같이 본 고안은 후면투사 조립식 멀티스크린 고정장치에 있어서, 스크린 고정프레임(10)의 폭이 좁아서 영상의 단절을 최소화하여 화면 연결이 잘되고 단위스크린이 전면에서 착탈자개하게 조립되므로 증설과 감축이 용이하고, 외관이 미려한 매우 실용적인 고안이다.The box body 1 of the present invention is assembled with left and right side plates (2) (2 '), top and bottom plates (3) (3'), and vertical transverse plates (6) (6 ') to provide a screen fixing compartment (1'). In addition, a plurality of inclined stone pieces 7 are formed on the front edge of the plate body surrounding each compartment 1 ', and the quadrangular gap 11' is deeply recessed in the inner edge so as to face the stone pieces 7. Assembling with screen fixing frames 6, 6 ', 6 "having a plurality of photo concave portions 11, the screen fixing compartment 1' is installed in parallel, and the front edge of the plate body surrounding each compartment 1 'is provided. Screen fixing frame (10) formed with a plurality of inclined protrusion pieces (7), and formed with a plurality of inclined concave parts (11) in which the quadrangular gap (11 ') is deeply indented and extended inwardly to face the stone pieces (7) (10 ') 10 "(10'") is attached to the stone piece 7 of the front edge of a side plate through the screen 9 in which the stone piece 8 was formed in the edge. Is a square shape deeply recessed at the rear of the screen fixing frames 10, 10 ', 10 "and 10'". Hanged by the gap 11 ', the screen 9 is supported between the concave portions 11 of the screen fixing frames 10, 10', 10 ", 10 '", and is inclined. And the screen fixing frames 10, 10 ', 10 " and 10' " are fastened to the respective side plates by means of the fasteners 12, the screen 9 is the screen fixing frames 10 and 10 '. (10 ") (10 '"), which is secured and secured, with the projections (7) in front of the longitudinal plate (6) and the transverse plate (6') and 6 "and the screen fixing frame (10) hanging thereon. The concave portion 11 of 10 ') 10 " (10' ") is twice as large as the projection 7 of the screen 9 because the screen 9, which is installed in the adjacent compartment 1 ', must be fixed in common. The concave convex part 11 may be formed, and the protrusion 7 of the screen 9 of the side compartment 1 'may be alternately rubbed. On the other hand, the screen fixing frames 10, 10 ', 10 " and 10' " are vertically and horizontally held so that they are securely fixed despite the load of the screen 9. As such, the present invention is a rear projection assembly type multi-screen fixing device, the width of the screen fixing frame (10) is narrow, minimizing the disconnection of the image is connected to the screen well and the unit screen is assembled detachably from the front, easy to expand and reduce It is a very practical design with beautiful appearance.
