본 고안은 차체의 중심지지대를 하부접지점에서 수직관을 입설하여 이에 차체의 전방지지간과 상부지지간을 관삽하고 관삽부의 수직관에 용착된 고정지지판에 보울트로 체결시켜 자전차를 펼치고 보울트를 해체시켜 접을 수 있게 한 절첩용 자전차에 관한 것으로 종래에도 자전차를 절첩하여 휴대하거나 보관할 수 있게 한 자전차가 있었으나 이들은 상부 평행지지관과 전방 삼각지지간을 분해조립할 수 있게 하였기 때문에 분해조립이 복잡하고 견고하게 조립할 수 없어 사고를 유발시키는 예가 허다하였고, 또 다른 절첩식 자전차는 앞삼각대와 뒷삼각대를 별개로 구성하여 이를 상호 유착시켜 고정보울트로 고정하는 동시에 앞바퀴부를 분해조립할 수 있게 하는 것들의 구조가 너무나 복잡하여 사용이 불편한 결점이 있었다.The present invention inserts a vertical tube from the lower ground point to the center support of the car body, inserts the front support part and the upper support part of the car body into the fixed support plate welded to the vertical pipe of the pipe insertion part, and unfolds the bicycle and disassembles the bolt. The folding bicycles were made in the related art. In the past, there were bicycles that could be folded and carried or stored. There have been many examples of accidents, and the other folding bicycles are so complex that the front and rear tripods are separately constructed and bonded to each other to fix them with high information and at the same time disassemble and assemble the front wheels. There was an uncomfortable fault.

이와 같은 결점을 감안하여 선출원한 실용신안 등록출원 82년 제5368호에서 개량고안한 것으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.In view of the above drawbacks, the proposed application for improvement in Utility Model Registration No. 5368 No. 82 filed in advance is described in detail with reference to the accompanying drawings.

차체(1)의 중심지지대(2)를 수직으로 입설시켜 상부를 후방으로 경사지게 만곡시키고 수직부(B)의 상하에 전방 경사지지대(3)와 상부지지대(4)를 회동할 수 있게 관삽시켜 공지한 보울트(3a) (4a)로 체결하고 중심지지대(2) 수직부(B)의 관삽부에 호형의 고정지지편(5) (5a)을 용착시켜 내측에 탄성편(6) (6a)을 착설하고 후방에 나사공(7) (7a)을 뚫어 전방경사지지대(3)와 상부지지대(4)에 용착된 보강편(8) (8a)에서 관통나합된 공지한 체결보울트(9) (9a)로 나합체결되게 하여서 된 것이다. 미설명부호 10은 안장이다.The central support 2 of the vehicle body 1 is vertically inserted to bend the upper portion to be inclined backwards, and the front inclined support 3 and the upper support 4 can be inserted into the upper and lower portions of the vertical portion B so as to be known. Fasten with one bolt (3a) (4a) and weld the arc-shaped fixed support pieces (5) (5a) to the pipe insertion portion of the vertical support (B) of the center support (2) to attach the elastic pieces (6) (6a) to the inside. The well-known fastening bolt 9 and 9a, which are installed and drilled through the reinforcing pieces 8 and 8a welded to the front slope support 3 and the upper support 4 by drilling screw holes 7 and 7a at the rear. It was made by uniting with). Reference numeral 10 is a saddle.

이상과 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as described above are as follows.

차체(1)의 중심지지대(2)를 수직으로 입설시켜 상부를 후방으로 경사지게 만곡시킨 다부에 안정(10)을 착설하고 중심지지대(2)의 수직부(B) 상하에 전방경사지지대(3)와 상부지지대(4)로 회동할 수 있게 관삽시켜 보울트(3a) (4a)로 체결하고 중심지지대(2) 수직부(B)의 관삽부에 용착된 호형 고정지지편(5) (5a)에 탄성편(6) (6a)을 삽착하여 후방에 나사공(7) (7a)을 뚫은 것에 전방경사지지대(3)와 상부지지대(4)에 용착된 보강편(8) (8a)에 관통나합된 체결보울트(9) (9a)를 나합고정하게 되면 차체(7)가 펼쳐져서 자전차를 탈수 있게 되고 체결보울트(9) (9a)를 풀면 전방경사지지대(3)와 상부지지대(4)를 제2도와 같이 후방으로 접을 수 있는바 자전차를 펼치거나 접기가 간편하고 호형 고정지지편(5) (5a)에 전방지지대(3)와 상부지지대(4)를 보울트(9) (9a)로 체결하게 되면 호형 고정지지편(5) (5a)에 삽착된 탄성편이 압축되면서 완강하게 고정되므로 자전차의 운전중에 차체가 요동됨이 없고 접었을 경우에는 휴대보관이 간편한 이점이 있는 것이다.The central support 2 of the vehicle body 1 is placed vertically, and the stabilizer 10 is installed in the ridge in which the upper portion is bent backwards, and the front slope support 3 is placed above and below the vertical portion B of the center support 2. To the arc-shaped fixed support piece (5) (5a) which is inserted into the pipe insertion part of the central support part (2) by fastening with the bolts (3a) and (4a) so as to be rotated by the upper support part (4). Insert the elastic pieces (6) (6a) through the screw holes (7) (7a) in the rear through the reinforcing pieces (8) (8a) welded to the front slope support (3) and the upper support (4). When the fastening bolts 9 and 9a are fastened, the vehicle body 7 can be unfolded to ride the bicycle, and when the fastening bolts 9 and 9a are loosened, the forward tilt support 3 and the upper support 4 are removed. It is easy to fold or fold the bike backwards as shown in 2 degrees, and fasten the front support (3) and the upper support (4) with the bolt (9) (9a) to the arc-shaped fixed support piece (5) (5a). Ho If the fixed support piece (5) so stubbornly fixed while the elastic side compression sapchak to (5a) there is no search body swings during the operation of the motorcycle it is folded to the advantage that the portable storage easy.

Claims
