본 고안은 절첩식 칠판에 관한 것으로서, 더욱 상세하게는 칠판을 이루는 후레임의 모서리결합을 용이하게 하고 칠판의 표면을 이루는 칠판의 고정이 견고하고 용이하도록 한 것이다.The present invention relates to a folding blackboard, and more particularly, to facilitate the corners of the frame forming the blackboard and to make the fixing of the blackboard forming the surface of the blackboard solid and easy.

특히, 본 고안은 본인의 선출원(실용신안등록출원 제94-12197호: 칠판구조)을 더욱 개량한 것으로서, 종래의 칠판은 예시도면 제1도 내지 제2도에 도시한 바와같이 고정칠판(100)의 전면에 경첩(101)을 이용하여 절첩할 수 있는 절첩식 칠판(102)이 결합되고, 절첩식 칠판(102)은 4각틀(103)의 전후면에 칠판으로 사용하기 위한 철판(104)을 결합하되, 철판(104)의 각 모서리부(105)를 따내어 4면의 단부를 4각틀(103)의 외측에서 내측으로 감싸듯이 접은후 스포트용접을 하였으며, 충진공(106)을 통하여 4각틀(103)과 전후면의 철판(104)이 이루는 육면체의 공간(107)내에 우레탄폼을 충진시키도록 되어 있었다.In particular, the present invention is a further improvement of his prior application (Utility Model Registration Application No. 94-12197: blackboard structure), the conventional blackboard is fixed board (100) as shown in Figures 1 to 2 of the exemplary drawings Foldable blackboard 102 that can be folded by using a hinge 101 is coupled to the front of the), the folding blackboard 102 is iron plate 104 for use as a blackboard on the front and back of the square frame 103 Combined, but each corner portion 105 of the iron plate 104 is folded to wrap the end of the four sides as the inner side from the outside of the square frame 103, and then spot welding, and through the filling hole 106 4 The urethane foam was filled in the space 107 of the hexahedron formed by the frame 103 and the iron plate 104 on the front and rear surfaces.

위와같이 4각틀내에 우레탄폼을 충진시키는 경우에는 전체적으로 칠판의 무게를 경감시킬 수 있으나 4각틀을 목재로 하였기 때문에 무거울 뿐만 아니라 철판을 4각틀의 외주에서 접은후에 스포트용접을 하는 등 제작시간이 많이 소요되며 정교함을 요하는 어려움이 있었다.In the case of filling urethane foam in the four-sided frame as above, it is possible to reduce the weight of the board as a whole, but since the four-sided frame is made of wood, it is not only heavy but also takes a lot of production time such as spot welding after folding the iron plate on the outer periphery of the four-sided frame. There was a difficulty that required sophistication.

본 고안은 상술한 바와같은 종래의 결점을 해결하기 위하여 칠판본체의 후레임을 4각파이프형의 알미늄샷시로 구성하고 중앙에 하나의 세로보강대를 설치하여 보강대 양측에 스티로폴판을 삽입하거나 우레탄폼을 충진시키고, 알미늄샷시로 구성된 후레임 외면에는 철판을 지지할 수 있는 지지홈 및 지지대를 형성함으로서 가볍고 견고하며 제작이 간편한 절첩식 칠판을 제공함에 목적이 있다.In order to solve the above-mentioned drawbacks of the present invention, the frame of the blackboard main body is composed of aluminum pipe of square pipe type and one longitudinal reinforcing bar is installed in the center to insert styropol plates on both sides of the reinforcing bar or to fill the urethane foam. In addition, the frame is made of aluminum sash the outer surface of the frame to form a support groove and support for supporting the iron plate is intended to provide a folding, lightweight, easy to manufacture folding board.

본 고안을 첨부된 예시도면과 함께 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.

본 고안은 후레임(1)을 4각파이프형의 알미늄샷시로 구성하고 모서리부(2)를 45도로 절단하여 연결구(3)로 결합시키도록 하고, 후레임(1)의 좌우양측에는 지지홈(4)을 형성하며, 후레임(1)의 상하 양측에는 지지대(5)를 결합하여 철판(6)을 지지하도록 한 것이다.The present invention consists of a frame made of aluminum pipe of the square pipe (1) and cut the corner portion 2 to 45 degrees to be coupled to the connector (3), the support grooves (4) on the left and right sides of the frame (1) ) And to support the iron plate (6) by coupling the support (5) to the upper and lower sides of the frame (1).

미설명부호 7은 후레임(1)으로 구성되는 후레임본체, 8은 후레임본체(7)내에 삽입되는 스티로폴판, 9는 연결구(3)의 절곡단부, 10은 연결구(3)의 모서리부, 11은 후레임(1)내에 형성된 돌기대, 12는 연결구(3)의 저부, 13,14는 각각 후레임(1)과 연결구(3)에 천공된 보울트공, 15는 경첩, 16은 지지목이다.Reference numeral 7 is a frame body consisting of a frame (1), 8 is a styropole plate inserted into the frame body (7), 9 is a bent end of the connector (3), 10 is a corner of the connector (3), 11 is Protrusions formed in the frame 1, 12 is the bottom of the connector 3, 13, 14 are the bolt hole perforated in the frame 1 and the connector 3, 15 is the hinge, 16 is the support wood.

상기와 같이 구성된 본 고안은 후레임본체(7)내에 스티로폴판(8)을 내입하여 그 양면에 철판(6)을 결합하도록 된 것으로서 후레임본체(7)내의 공간이 넓은 경우에는 중앙에 세로방향으로 보강대를 설치하여 그 양단에 스티로폴판(8)을 결합 또는 우레탄폼을 충진시키는 것이다.The present invention configured as described above is to incorporate the styropole plate 8 into the frame body 7 to couple the iron plate 6 to both sides thereof, and when the space in the frame body 7 is large, the reinforcing bar is vertically in the center. By installing the styropole plate 8 is coupled to either end or to fill the urethane foam.

후레임본체(7)의 전,후면에 철판(6)을 결합할때는 철판(6)의 좌우양단이 지지홈(4)내에 삽입되어 끼워지도록 하고, 상하양단은 지지대(5)가 지지하도록 한 것이다. 따라서 지지대(5)의 내측 홈은 후레임(1)과 2개의 철판(6)을 동시에 끼울 수 있는 크기로 구성된다. 각 후레임(1)의 결합은 모서리부(2)를 45도로 절단하여 연결구(3)의 양단을 각 후레임(1)의 모서리부(2)내로 삽입한 후 보울트공(13)(14)을 일치시켜 보울트를 나합함으로서 이루어지는데, 연결구(3)를 모서리부(2)에 삽입하면, 연결구(3)의 저부(12)가 후레임(1)의 내측에 형성된 돌기대(11)상에 꼭맞도록 되어 있으며, 동시에 절곡단부(9)가 후레임(1)내측 상단에 밀접될 뿐만 아니라, 연결구(3)의 모서리부(10)도 절곡단부(9)와 동일한 높이로서 후레임(1)의 내측상단에 밀접되므로 후레임(1)과 인접한 후레임(1)은 견고히 결합되는 것이다.When the iron plate 6 is coupled to the front and rear of the frame body 7, the left and right ends of the iron plate 6 are inserted into the support groove 4 to be fitted, and the upper and lower ends are supported by the support 5. Therefore, the inner groove of the support 5 is configured to fit the frame 1 and the two iron plate 6 at the same time. The combination of each frame 1 cuts the corner portion 2 to 45 degrees, inserts both ends of the connector 3 into the corner portion 2 of each frame 1, and coincides with the bolt balls 13 and 14. It is made by screwing the bolts. When the connector 3 is inserted into the corner portion 2, the bottom portion 12 of the connector 3 fits snugly on the protrusion 11 formed inside the frame 1. At the same time, the bent end 9 is not only close to the upper end of the frame 1, but also the edge 10 of the connector 3 is also close to the inner top of the frame 1 at the same height as the bent end 9. Therefore, the frame (1) and the adjacent frame (1) is to be firmly coupled.

예시도면 제4도는 경첩(15)결합부를 확대도시한 것으로서, 경첩(15)을 결합하는 부위는 지지홈(4)을 약간 제거하여 경첩으로 인한 양측 칠판간의 거리가 생기지 않도록 한 것이다.4 is an enlarged view of the hinge unit 15, and the hinge unit 15 is coupled to a portion of the support groove 4 so as not to generate a distance between the two boards due to the hinge.

철판(6)은 그 이면에서 스티로폴판(8)과 접착되어 있을뿐만 아니라 지지대(5)에 의해 지지되므로 요동이 없게 되고, 지지대(5)는 후레임본체(7)에 리벳팅되어 있으므로 사용시 또는 운반시에 들뜨거나 이탈되지 않게 된다.The iron plate 6 is not only bonded to the styropole plate 8 on the back side thereof but also supported by the support 5 so that there is no swing, and the support 5 is riveted to the frame body 7 so that it is used or transported. You won't be lifted or escaping the poem.

본 고안은 가벼운 재질인 알미늄샷시로 후레임이 구성되고 4각파이프형태로 구성되어 가볍고 견고할 뿐만 아니라, 연결구로 연결되므로 각 모서리부가 견고하며, 상,하부에는 지지대가 리벳팅되어 철판을 견고히 지지하므로 철판(6)의 단부가 들뜨거나 분리되지 않는 효과가 있다.The present invention is made of aluminum sash, which is a lightweight material, and consists of a square pipe shape, which is not only light and strong, but also connected to the connector so that each corner is solid, and the upper and lower parts are riveted to support the steel plate. There is an effect that the end of the iron plate 6 is not lifted or separated.
