본 고안은 고정 칠판이 형성되고 그 칠판의 전면으로 미닫이식 칠판과 경첩에 의하여 회동되는 회동칠판을 부설한 개폐식 칠판에 있어서 회동 칠판의 회동을 원활하게 함과 동시에 칠판의 집중하중에 대하여 충분히 견딜 수 있도록 하여 칠판의 사용수명을 길게 한 개폐식 칠판용 경첩에 관한 것이다.The present invention is a retractable blackboard in which a fixed blackboard is formed and a sliding blackboard and a sliding blackboard pivoted by a hinge are provided on the front of the blackboard to smoothly rotate the rotating blackboard and to withstand the concentrated load of the blackboard. It relates to a hinge for a retractable blackboard which extends the service life of the blackboard.

본원 출원인은 본인의 선출원인 1986년 실용신안등록출원 제 7742호(공고번호 : 89-2932)에서 칠판의 저면부와 칠판의 정면부를 나사못으로 고정시키도록 한 경첩의 축을 저면부 외곽틀체의 상부에 고정된 고정목의 축삽입공에 삽입시킨 경첩이 부설된 다용도 칠판을 제안한 바 있다.The applicant of the applicant's application in 1986, Utility Model Registration Application No. 7742 (Notice: 89-2932), the shaft of the hinge which fixes the bottom part of the board and the front part of the board with a screw on the upper part of the bottom frame. A multi-purpose blackboard with hinges inserted into the shaft insertion hole of a fixed fixture has been proposed.

그런데 상기한 본인의 선출원에서의 경첩은 회동칠판의 상, 하부에 고정되는 "ㄱ"자형 고정편이 외부로 노출되어 외관을 해하였고 이 노출된 고정편으로 인하여 칠판지우개의 외피를 상하게 하는 등의 문제점이 있었던 것이다.However, the above-mentioned hinge in my application is a problem that the "a" shaped fixing piece fixed to the upper and lower parts of the rotating blackboard is exposed to the outside and damaged the appearance, and the exposed fixing piece damages the outer cover of the blackboard eraser. This was there.

따라서 상기 결점을 보완하는 것으로 실용신안공보 제 1718호(공고번호 : 93-717)에 칠판테에 삽지공과 절곡받침편을 형성한 고정판을 고정하고 경첩핀을 삽지공에 끼우도록 하여 경첩핀을 길게 연장하고 보조편을 ㄱ자형으로 절곡시켜서 된 절첩식 칠판의 경첩이 제안되어 칠판지우개의 외피를 상하게 하는 것을 방지케 하였으나 상기 구성으로는 절첩식 칠판의 집중하중을 경첩에서 받게되는데 이때 경첩이 집중하중을 견디지 못하고 휨이 발생되어 절첩식칠판의 개폐를 원활하게 하지 못한게 되므로서 결국 절첩식칠판의 수명을 단축케 하여 수요자들로 하여금 환영을 받지 못하였던 것이다.Therefore, to compensate for the above deficiency, Utility Model Publication No. 1718 (Notification No. 93-717) secures the fixing plate formed with the insertion hole and the bending support piece on the blackboard frame, and the hinge pin is inserted into the insertion hole to extend the hinge pin. And the hinge of the folding board was made by bending the auxiliary piece to the "A" shape to prevent damaging the outer shell of the eraser.However, the above configuration receives the concentrated load of the folding board from the hinge. It could not endure the bending and the opening and closing of the folded blackboard could not be smooth and eventually shortened the life of the folded blackboard was not welcomed by the customers.

본 고안은 상기와 같은 문제점들을 감안하여 개폐식 칠판의 전면에 경첩부위가 노출되지 아니하고 또한 칠판의 집중하중에 대하여 충분히 견딜 수 있는 경첩을 제공하여 장기간 아무문제없이 사용할 수 있도록 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention, in view of the above problems, the hinge portion is not exposed on the front of the retractable blackboard and provides a hinge that can withstand the concentrated load of the blackboard enough to be used for a long time without any problem. When described in detail as follows.

칠판(11)의 양측으로 게시판(12) (12')을 위치고정시키고 그 전면으로 미닫이식 교육칠판(13) (13')을 설치시킨후, 그 전면에 경첩에 의하여 축지지되어 개폐되도록 한 개폐칠판(14) (14')을 설치한 통상의 것에 있어서 개페칠판(14) (14')의 상, 하단에 고정금구(4)로 고정되는자형 고정판(3)의 측면중앙에 축삽입구멍(2)이 상, 하로 관통된 지지간(1)을 용착시키고 이와 대응되는 칠판틀체(10) 표면에 고정축(5)을 용착고정시킨자형 받침판(6)을 고정금구(4')로 고정시켜서 된 것이다.Position the bulletin board 12 (12 ') on both sides of the blackboard 11, and install the sliding education blackboard 13 (13') on the front side of the board 11, and then axially supported by the hinge to open and close the front. In the normal one provided with the opening and closing blackboards 14 and 14 ', the fixing bracket 4 is fixed to the upper and lower ends of the opening boards 14 and 14'. The support shaft 1 through which the shaft insertion hole 2 penetrated up and down is welded on the side center of the female fixing plate 3, and the fixing shaft 5 is welded and fixed on the surface of the board frame 10 corresponding thereto. The female base plate 6 is fixed by the fixing bracket 4 '.

그리고 칠판틀체(10)의 표면부와 받침판(6)이 사이에는자형 보강간(7)을 삽입시켜 고정금구(4')로 받침판(6)을 고정시킬때 받침판(6), 보강간(7), 틀체(10)가 고정금구(4')에 의하여 동시에 고정되도록 하므로서 개폐칠판(14) (14')의 사용에 의하여 고정금구(4')가 틀체(10)의 내측에서 강한 하중에도 견디고 유동되는 것 또한 미연에 방지하도록 하였다.And between the surface portion of the blackboard frame body 10 and the support plate 6 When the supporting plate 6 is fixed by the fixing bracket 4 'by inserting the male reinforcing bar 7, the supporting plate 6, the reinforcing bar 7, and the frame 10 are simultaneously fixed by the fixing bracket 4'. By using the opening and closing blackboard 14 (14 '), the fixing bracket 4' withstands the heavy load and flows inside the frame 10 and prevents it from flowing.

이를 실시하기 위한 실시예로서 고정금구(4')를 나사못으로 하는 경우 나사못의 나선부분이 보강간(7)의 구멍에 결합되므로서 개폐칠판(14) (14')이 회동 개폐될때의 하중을 보강간(7)에서 받아주어 틀체(10)의 내부와 나사못사이에 공간부가 생기게되는 것을 방지케 할 수 있다.As an embodiment for carrying out this, when the fixing bracket 4 'is screwed, the threaded portion of the screw is coupled to the hole of the reinforcing rod 7, so that the load of the blackboard 14 and 14' is rotated. Received in the reinforcing bar (7) can be prevented from creating a space between the interior of the frame 10 and the screw.

도면중 미설명부호 8은 고정축(5)에 삽입되어 받침판(6)과 지지간(1)사이에 위치되는 와셔이다.In the figure, reference numeral 8 denotes a washer inserted into the fixed shaft 5 and positioned between the support plate 6 and the support member 1.

상술한 바와 같은 본 고안은 첨부도면 제 1, 3 도에서 예시한 바와같이 여러 종류의 교육용 칠판을 하나의 틀체에 형성하여 교육효과를 높이기 위한 개폐식 칠판에 있어서, 상, 하부에 설치된 경첩에 의하여 회동되는 개폐식칠판의 개폐를 원활하게 함과 동시에 개폐칠판의 개폐작동시에 생기는 집중하중에 대하여 충분히 견딜수 있게 하므로서 그 수명을 장구하게 하기 위한 목적으로 사용되는 것이다.The present invention as described above in the retractable blackboard to increase the educational effect by forming a variety of educational blackboards in one frame as illustrated in Figures 1 and 3 of the accompanying drawings, rotated by hinges installed on the upper and lower parts It is used for the purpose of making the opening and closing of the retractable board smooth and at the same time being able to withstand the concentrated load generated during the opening and closing operation of the opening and closing board to prolong its life.

즉, 본원고안은 첨부도면 제 2, 4, 5 도에 예시한 바와같이 개폐칠판(14) (14')의 상, 하단에 고정금구(4)로 고정되는자형 고정판(3)의 측면 중앙에 축삽입구멍(2)이 상, 하로 관통된 지지간(1)을 용착시키고 이와 대응되는 칠판틀체(10)표면에 고정축(5)을 융착 고정시킨자형 받침판(6)을 고정금구(4')로 고정시킨 구조로 되어 있으므로 개폐칠판(14) (14')의 희동시에 그 집중하중이 고정축(5)과 고정판(3)과 받침판(6) 세군데로 분산되어 고정축(5)이 무리한 힘을 받지 않게 된다.That is, the present application is fixed to the upper and lower sides of the opening and closing blackboard 14, 14 'as illustrated in the attached drawings 2, 4, 5 is fixed with a fixing bracket (4) The support shaft 1 through which the shaft insertion hole 2 penetrates up and down is welded to the center of the side of the female fixing plate 3, and the fixing shaft 5 is fusion-fixed to the surface of the blackboard frame body 10 corresponding thereto. Since the support plate 6 is fixed by the fixing bracket 4 ', the concentrated load is fixed at the time of the opening and closing of the blackboard 14 or 14' with the fixed shaft 5, the fixed plate 3, and the support plate 6 It is dispersed in three places so that the fixed shaft (5) is not subjected to excessive force.

따라서 개폐칠판(14)(14')을 교육적 효과를 위하여 개폐시키거나 또는 고정칠판(11)의 사용시 고정칠판(11)의 양측에서 들어오는 햇빛을 차단시키기 위하여 곡면칠판(14) (14')을 제 1 도에서와 같이 경사진 각도로 위치시키는 등, 개폐칠판(14) (14')을 자주 개폐시키더라도 경첩자체에 무리한 힘이 전달되지 아니하며 고정개폐식 칠판을 장기간동안 고장없이 사용할 수 있는 유용한 고안인 것이다.Therefore, to open and close the opening and closing blackboard (14, 14 ') for the educational effect or to block sunlight coming from both sides of the fixed blackboard (11) when using the fixed blackboard (11) Even if the blackboard 14 and 14 'are frequently opened and closed, such as being positioned at an inclined angle as shown in FIG. 1, the forceless force is not transmitted to the hinge itself. It is
