본 고안은 칠판에 관한 것으로. 특히 곡면으로 설치되는 칠판을 안전적으로 견고하게 고정하도록 안출한 칠판고정구조에 관한 것이다.This invention is about the blackboard. In particular, the present invention relates to a blackboard fixing structure designed to safely and firmly fix a blackboard installed as a curved surface.
일반적으로 칠판은 상호 대각선방향에서도 볼 수 있도록 설정된 곡률반경을 가지는 곡면으로 설치하고 있다. 이러한 고정식 칠판은 그 자체만을 설치하거나, 고정칠판을 포함하여 미닫이칠판 및 회동식칠판 등 여러 가지 형태로 제작된 학습자료용 수개의 칠판을 하나의 틀체에 설치하여 필요에 따라 원하는 칠판을 개폐시켜 사용할 수 있도록 구성된 다기능 칠판에 설치하는 경우도 있다.In general, the board is installed as a curved surface having a curvature radius set so that it can be seen even in a diagonal direction. These fixed boards can be installed by themselves or by installing several blackboards for learning materials in various forms such as sliding boards and rotating boards, including fixed boards, in one frame. Sometimes it is installed on a multifunctional blackboard that is configured to do so.
그런데 이러한 고정식칠판은 대부분 목재이고 또한 이를 구성하기 위한 틀체도 목재로 제작되고 있어, 이들의 제작시 칠판이 설정된 곡률로 형성되기 위하여 틀체를 구성하는 양측벽에 칠판을 못등으로 고정시키고 있는 실정이다.By the way, such a fixed board is mostly wood and the frame for constituting it is also made of wood, the situation of fixing the blackboard with nails on both sides of the frame constituting the frame to form the curvature at the time of their production.
이때, 칠판을 설정된 곡률로 형성하기 위하여 칠판을 휘었을 경우 양측 주연에 작용하는 휨모멘트가 상당히 강하기 때문에 양측틀체에 칠판의 주연의 고정시 많은 갯수의 못을 사용하지 않으면 안되고, 이로인해 제작공수의 증가와 제작의 어려움으로 생산성의 감소원인이 되는 결점이 있었다.At this time, when the board is bent to form the curvature of the board, the bending moment acting on both sides of the board is very strong. Therefore, a large number of nails must be used when fixing the board around the frame. Increasing and difficult manufacturing have the drawback of reducing productivity.
본 고안은 이러한 종래의 문제점을 해결하고자 안출한 것으로, 틀체를 알루미늄 금속재로 제작하여 강도 및 지지력을 높히도록 하고, 칠판의 양측 주연을 고정시키기 위해 양측벽에 받침턱을 돌출 형성한 뒤 그 받침턱에 칠판의 양측 주연을 고정시키도록 하므로서, 제작의 편리함과 공수의 절감으로 생산성을 향상시키고자 하는데 그 목적이 있다.The present invention was devised to solve such a conventional problem, and the frame is made of aluminum metal to increase the strength and bearing capacity, and to form the protruding jaw on both side walls to fix the periphery of the board and then the jaw The purpose of this is to improve the productivity by the convenience of production and the reduction of labor by fixing both sides of the blackboard.
이하 본 고안을 첨부도면에 의하여 상세히 설명한다.Hereinafter, the present invention will be described in detail by the accompanying drawings.
도면 제1도 내지 제4도는 본 고안의 실시예로서, 틀체(10)의 양측벽(11)에 칠판(20)의 양측 끝단(21)을 고정시키도록 한 것에 있어서, 상기 특체(10)는 알루미늄 금속재로 압출성형한 뒤 설정된 규격으로 절단 및 제작하고, 상기 양측벽(11)의 내측벽(12)에는 길이방향으로 받침턱(13)을 돌출형성하여 설정된 곡률반경으로 칠판(20)의 휨발생시 그 양단에 작용하는 휨모멘트를 양측벽(11)의 내측면(12)과 받침턱(13)이 각각 양측 주연(22)과 양측 끝단(21)을 받쳐 주도록 하며, 상기 칠판(20)의 양측 끝단(21)을 받침턱(13)에 고정나사(30)로 고정시켜 주도록 한 것이 본 고안의 특징이다.1 through 4 are embodiments of the present invention, in which both end portions 21 of the blackboard 20 are fixed to both side walls 11 of the frame 10, the feature 10 is After extruded with aluminum metal material and cut and manufactured to the set standard, the inner wall 12 of the both side wall 11 is formed by protruding the base jaw 13 in the longitudinal direction to bend the blackboard 20 with the set curvature radius. When generated, the bending moments acting on both ends of the inner wall 12 and the supporting jaw 13 of both side walls 11 support the two peripheral edges 22 and both end 21, respectively. It is a feature of the present invention that both ends 21 are fixed to the base jaw 13 with a fixing screw 30.
틀체(10)에 칠판(20)의 고정시 사용되는 고정나사(30)의 고정위치와 수량은 칠판(20)을 고정시킬 수 있을 정도로 설계하여 제작공수와 편리함을 주어 생산성을 향상시키도록 하는 것이 바람직하다.The fixing position and the number of fixing screws 30 used to fix the board 20 to the frame 10 are designed to fix the board 20 so that the productivity and convenience are improved to increase productivity. desirable.
그리고 상기 받침턱(13)과, 칠판(20)의 양측 끝단(21)에 각각 나사조립구멍을 설정된 위치에 각각 형성하며, 이는 칠판(20)의 설치시 동시에 뚫어도 무방하다.In addition, the support jaw 13 and the screw assembly holes are respectively formed at predetermined positions on both ends 21 of the blackboard 20, which may be drilled at the same time when the blackboard 20 is installed.
이와같이 구성된 본 고안은, 틀체(10)에 칠판(20)의 설치시 칠판(20)이 설정된 곡률반경으로 휘어지도록 칠판의 길이를 틀체(10)보다 크게 제작한 뒤, 칠판(20)의 양측 주연(22)이 각각 틀체(10)의 양측벽(11)의 내측면(12)에 밀착되게 칠판(20)을 굴곡시키면 양측 끝단(21)은 양측벽(11)에 돌출된 받침턱(13)에 걸리게 되므로 칠판(20)의 휨모멘트는 양측벽(11)의 내측면(12)과 받침턱(13)에 각각 전달되어 견고하게 지지된다.According to the present invention configured as described above, the length of the board is made larger than the frame 10 so that the board 20 is bent at a set curvature radius when the board 20 is installed on the frame 10, and both sides of the board 20 are cast. When the boards 20 bend the boards 20 so as to be in close contact with the inner surfaces 12 of the side walls 11 of the frame 10, respectively, the end portions 21 of the base wall 13 protrude from the side walls 11. Since the bending moment of the blackboard 20 is transmitted to the inner surface 12 and the support jaw 13 of both side walls 11, respectively, it is firmly supported.
그 후 칠판(20)의 양측 끝단(21)을 틀체(10)의 받침턱(13)에 고정시키기 위하여 양측 끝단(21)과 받침턱(13)에 동시에 나사조립구멍을 뚫어서 고정나사(30)로 조립하거나, 미리 고정나사(30)의 조립위치에 나사조립구멍을 뚫은 뒤 고정나사(30)를 조립하여 틀체(10)에 칠판(20)을 고정시키도록 한다.Then, to fix both ends 21 of the blackboard 20 to the support jaw 13 of the frame 10, a screw assembly hole is drilled into both ends 21 and the support jaw 13 at the same time to fix the screw 30. Or assembling the screw assembly hole in the assembly position of the fixing screw 30 in advance, and then assembling the fixing screw 30 to fix the blackboard 20 to the frame 10.
이와 같이 본 고안은 칠판(20)의 양측 끝단에 작용하는 휨모멘트를 금속재인 틀체(10)의 양측벽(11)이 견고하게 지지하여 주는 동시에 양측벽(11)에 돌출된 받침턱(13)에 양측 끝단(21)을 고정나사(30)로 간단하게 조립고정하여 주므로서 제작이 매우 편리하고, 제작공수도 줄일 수가 있어 생산성을 향상시킬 수 있는 매우 유용한 고안인 것이다.As described above, the present invention supports both side walls 11 of the frame 10 made of metal and firmly supports the bending moments acting on both ends of the board 20, and at the same time, protrudes from the side walls 11. By simply assembling and fixing both ends 21 to the fixing screw 30, the production is very convenient, and the manufacturing work can be reduced, which is a very useful design that can improve productivity.
