Folding device

제1도는 본 고안의 사시도.1 is a perspective view of the present invention.

제2도는 본 고안의 요부를 발췌한 상태의 확대 사시도.Figure 2 is an enlarged perspective view of the state of extracting the main portion of the present invention.

제3도는 본 고안의 하부에 부착하는 상태의 요부 분해사시도.Figure 3 is an exploded perspective view of the main part attached to the lower portion of the present invention.

본 고안은 흑판의 전면 양측에 별도의 양면 흑판을 절첩토록 부착하여 절첩 작용을 장기간에 걸쳐서 사용하여도 마모가 되지않고 고장이 없으며 탈리되지 않을 뿐 아니라 지지력이 견고하면서 절첩작용이 용이하도록 개량한 흑판의 절첩장치에 관한 것이다.The present invention attaches separate double-sided boards on both sides of the front of the board, so that even if the folding action is used for a long time, it does not wear out, there is no breakdown, it does not come off, and the supporting force is solid and the folding board is easily improved. It relates to a folding device.

종래의 본원 출원인이 선등록한 79-972호로 공고된 다면을 형성한 개량흑판은 절첩작용이 불편하고 장기간 절첩사용하게 되면 마모로 인해 탈리가 되며 절첩시에 정확한 위치에 절첩 위치되지 않고 견고성이 없는 등의 문제점이 대두되었던 것이다.The improved black board which forms a multi-faceted surface as announced by the applicant of the prior application No. 79-972 is uncomfortable to the folding action, and when it is used for a long time, it is detached due to abrasion, and is not folded at the correct position at the time of folding and has no firmness. The problem has arisen.

본 고안은 이와 같은 선등록한 다면을 형성한 개량흑판의 문제점을 근본적으로 해결 및 보완하여 절첩작용이 용이하고 고장이 없으며 견고하여 조기마모의 폐단이 없어 사용중 탈리되지 않을뿐 아니라 특히 절첩작용이 원활하도록 안출한 것으로서 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention fundamentally solves and complements the problems of the improved black board which forms such a pre-registered facet, so that the folding action is easy, there is no breakdown, and it is solid, there is no closing of the early wear, so that it is not detached during use, and especially the folding action is smooth. When described in detail by the accompanying drawings as a draft as follows.

흑판(1) 전면에 보조흑판(2)을 부착하고 양면에 절첩흑판(3)(3')를 형성한 것에 있어서, 흑판(1)의 상하양면의 보조흑판(2) 양단부 지점에 삽지공(7)이 천설되고 돌편(6)을 돌설시킨 고정편(4)을 부착하고 축핀(10)을 축삽하여 돌기(11)을 돌설시킨 경첩(8)(8')를 보조흑판(2) 상하양단과 절첩흑판(3)(3') 내접단면 상하부에 부착하여 돌기(11)을 삽지공(7)에 유삽케 하여서 됨을 특징으로 한 것이다.In the case where the auxiliary black board 2 is attached to the front of the blackboard 1 and the folded black boards 3 and 3 'are formed on both sides, insertion holes 7 are provided at both ends of the auxiliary black board 2 of the upper and lower surfaces of the black board 1, respectively. ) And a hinge (8) (8 ') in which the projection (11) is protruded by attaching the fixing piece (4) which is installed and protrudes the stone piece (6) and the shaft pin (10). It is characterized in that the projection 11 is attached to the upper and lower folds of the folded blackboard 3 and 3 'to induce the insertion hole 7 into the insertion hole 7.

미설명부호 5, 9, 9'는 보울트공, 12, 12'는 협지편이다.Unexplained symbols 5, 9 and 9 'are bolted balls, and 12 and 12' are pinched pieces.

이와 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as follows.

먼저 흑판(1)의 전면 중앙에 보조흑판(2)을 부착하고 보조흑판(2)의 양단면부 상하위치의 중심지점에 고정편(4)을 보울트로 조여서 고정한다. 그리고 양측의 절첩흑판(3)(3')을 보조흑판(2)의 전면부로 접속시켜서 보조흑판(2)의 단면과 절첩흑판(3)(3')의 단면을 일치시킨 후 돌기(11)를 삽지공(7)에 끼운 다음 경첩(8)은 보조흑판(2)의 단면에 보울트로 보울트공(9)에 나착하여 고정하고 경첩(8')는 절첩흑판(3)의 단면부에 보울트로서 보울트공(9')에 나착하여 고정한다. 즉 이와 같은 방법으로 하단부와 타측의 상하면도 동일하게 조립 후 절첩흑판(3)(3')를 제쳐서 흑판(1)에 접속시키면 보조흑판(2)과 평면을 이루게 된다. 절첩사용시에는 상하축핀(10)의 돌기(11)이 돌편(6)의 삽지공(7)에 유삽 지지되어 절첩판(3)(3')이 절첩작용케 됨으로 고장이 나지 않고 사용도중 탈리되거나 마모가 되지 않으며 견고하게 된다.First, the subsidiary blackboard 2 is attached to the center of the front surface of the blackboard 1, and the fixing piece 4 is fixed to the center of the upper and lower positions of both end surfaces of the subsidiary blackboard 2 by tightening with a bowl. Then, the folding blackboards 3 and 3 'on both sides are connected to the front portion of the auxiliary blackboard 2 so that the cross section of the auxiliary blackboard 2 and the cross section of the folding blackboard 3 and 3' are aligned, and then the projection 11 To the insertion hole 7 and then the hinge 8 is bolted to the bolt hole 9 with a bolt on the end face of the auxiliary blackboard 2 and the hinge 8 'is bolted to the end face of the folded blackboard 3. Fix it by screwing on the bolt hole (9 '). In other words, when the lower end and the upper and lower surfaces of the other side are assembled in the same way, the folding black boards 3 and 3 'are connected to the black board 1 to form a flat surface with the auxiliary black board 2. In folding use, the projection 11 of the upper and lower shaft pins 10 is supported by the insertion hole 7 of the stone piece 6 so that the folding plates 3, 3 'are folded, so that the folding plates 3 and 3' do not fail and are detached or worn during use. Will not be and will be firm.

이와 같이 된 본 고안은 흑판에 여러면을 이용할 수 있으며 신속하게 절첩사용케 되는 효과적인 것이다.In this way, the present invention can use multiple surfaces on the blackboard and it is effective to be folded quickly.

Claims
