본 고안은 접는 자전거로서 좁은 공간을 이용해야 하는 현대사회에서 개인의 운반수단과 좁은 공간에서의 보관방법, 고층화시대의 고층에서의 보관 및 운반등을 보다 편리하게 하기 위한것으로서 본인이 선출원 공고된 실용신안 제86-455호의 절첩용 자전거를 개량발전시킨 것으로서 선출원 공고된 실용신안 제86-455호는 접거나 펼쳐서 자전거를 타는데는 더없이 튼튼하고 좋으나 중심지지대의 상하지지대 및 호형 고정지지편을 제작함에 있어서 제작비가 많이들고 제작과정이 까다로워 원가상승의 요인이 되며 체결볼트를 상하 2군데를 체결하므로 접고 펼치는데 번거로움과 많은 시간이 소요되었는바 제작원가를 낮출수 있으며 10초 이내에 접고 펼칠수 있게 개량 고안된 것으로 상세히 설명하면 다음과 같다.The present invention is intended to make personal transport and storage in narrow spaces and storage and transport on high floors of the high-rise era more convenient in modern society where folding spaces should be used. Utility Model No. 86-455, which was previously announced as an improvement of the folding bicycle of Shinan No. 86-455, is strong and good for riding a bicycle by folding or unfolding it, The production cost is high and the production process is difficult, which is a factor of the increase in cost, and the fastening and unfolding of two fastening bolts are fastened and unfolded, and it takes a lot of time and effort to reduce the production cost. It is designed to be folded and unfolded within 10 seconds. It will be described in detail as follows.

차체(1)의 중심지지대(2)를 수직으로 입설시켜 하단에 하부지지간(4) 가운데 중앙교정부(6) 상단에 상부지지간(3)이 되게 중심지지대(2)에 관삽시키고 그 상단에는 중간 연결관(5)을 중심지지대(2) 상단에 관삽시켜 용착하고 중심지지대(2)에 관삽된 상부지지간(3)과 하부지지간(4)은 회동할수 있게 하며 가운데 중앙고정부 (6)는 전방을 향하게 하여 중심지지대(2)에 용착하고 전방고정부(7)의 철판을 상부지지간(3) 후단 우측면과 하부지지간(4) 후단우측면에 용착하여 상하지지간(3)(4)이 별개일때의 삐거덕거림을 막음과 동시에 자전거를 펼쳐서 고정시킬때 중앙고정부(6)와 튼튼하게 고정할수 있는 고정부가 되게하고 숫나사부(7-1)는 숫나사의 양측면을 절삭(7-2)시켜 0모양되게 하며 숫나사부(7-1)를 전방고정부(7)의 가운데 구멍에서 흘러 빠지지않게 수용하고 중앙고정부(6)의 가운데 암나사부(6-1)는 암나사부(6-1)의 양측이 홈이되게 절삭 숫나사부(7-1)가 들어갈수 있게 장홈부(6-2)를 형성시켜서 자전거를 펼쳐서 고정시킬때는 숫나사부(7-1)를 암나사의 장홈부 (6-2)에 삽입시켜 1/4 바퀴만 우회전 시키면 숫나사부(7-1)의 나사와 암나사부(6-1)가 결합되어 고정되므로 자전거를 탈수 있으며 좁은 장소나 운반등 필요에 따라 접어야할 경우에는 숫나사부(7-1)를 1/4만 좌회전시키면 숫나사부(7-1)의 나사가 암나사부(6-1)에서 벗겨져서 장홈부 (6-1)로 빠져 나오므로 앞차체전체를 180°회전시켜서 접어지는 자전거이다.The center support 2 of the vehicle body 1 is vertically inserted and inserted into the center support 2 so that the upper support section 3 is formed at the upper end of the central correction section 6 among the lower support sections 4 at the lower end thereof. The intermediate connecting pipe (5) is inserted into the upper end of the center support (2) for welding, and the upper support section (3) and the lower support section (4) inserted into the center support section (2) are pivotable. The upper and lower limbs (3) and (4) are separated by welding the steel plate of the front fixing part (7) on the right side of the rear end of the upper support section (3) and the right rear side of the lower support section (4). At the same time to prevent the squeaky and at the same time to unfold the bicycle to fix the central fixing part (6) and the fixing part that can be securely fixed, the male part (7-1) is to cut (7-2) both sides of the male screw 0 The male part (7-1) from the center hole of the front fixing part (7) The female thread portion 6-1 in the center of the Ango government 6 forms a long slot portion 6-2 to allow the cutting male thread portion 7-1 to enter the groove so that both sides of the female thread portion 6-1 are grooved. To fix it, insert the male part (7-1) into the long groove (6-2) of the female thread, and turn it only 1/4 turn to turn the screw and the female part (6-1) of the male part (7-1). Since it is combined and fixed, it is possible to ride a bicycle and when it is necessary to fold as needed in a narrow place or transport, if the male screw part 7-1 is turned 1/4 left, the male screw part 7-1 is screwed on the female thread part 6-1. It is peeled off from) and comes out to the long groove (6-1), so it is a bicycle that is folded by rotating the whole front body 180 °.

이와 같이 구성된 본 고안은 중심지지대(2)의 가운데 중앙고정부(6)와 전방고정부(7)가 전후 차체를 고정되게 하므로서 제작과정의 어려움과 제작비를 줄일 수 있으므로 소비자에게 보다 싼값의 접는 자전거를 제공할수가 있으며 체결볼트 숫나사부 (7-1)의 양면을 절삭(7-2)하고 암나사부(6-1)의 양측 안쪽을 절삭 장홈부 (6-2)를 형성 하므로서 걸림없이 숫나사부(7-1)가 장홈부(6-2)에 단번에 삽입되거나 빠져나올수 있으므로 나사숫자만큼 회전시켜야만 고정되거나 풀리는 일반볼트의 체결보다 빠르며 간단하게 원텃치로 자전거를 접었다 펼칠수 있는 잇점이 있다.The present invention configured as described above allows the central fixing part 6 and the front fixing part 7 of the center support 2 to be fixed to the front and rear bodies, thereby reducing the difficulty and manufacturing cost of the manufacturing process. It is possible to provide the cutting bolt male part (7-1) by cutting both sides (7-2) and both sides of the internal threaded portion (6-1) to form a cutting long groove (6-2), so that the male thread portion ( 7-1) can be inserted into or out of the long groove 6-2 at once, so it must be rotated by the number of screws, which is faster than the fastening of general bolts and has the advantage of simply folding and unfolding the bicycle in one-touch.
