본 고안은 3륜자전거로 사용함과동시에 제3륜을 절첩하여 2륜자전거로도 사용할 수 있는 2륜 및 3륜겸용의 절첩식 3륜자전거에 관한 것이다.The present invention relates to a two-wheeled and three-wheeled folding three-wheeled bicycle that can be used as a two-wheeled bicycle by folding the third wheel at the same time as a three-wheeled bicycle.

종래에는 공고번호 77-223호에 의하여 2륜, 3륜겸용 자전거가 공지되어 있었으나, 이와같은 자전거는 제3륜의 후레임과 후속륜(자전거 뒷바퀴)의 후레임의 일체로 조립 구성되어 있어서 제3륜을 후속륜에 간단히 절첩이 불가능하므로 3륜으로 사용하다가 제3륜이 불필요할 경우에는 제3륜을 일일히 분해해야되는 폐단이 있었다.Conventionally, two- and three-wheeled bicycles are known according to the notification No. 77-223, but such bicycles are constructed by integrally combining the frame of the third wheel and the frame of the subsequent wheel (rear wheel). Since it is impossible to simply fold the subsequent wheel, it was used as a three wheel, and when the third wheel was unnecessary, there was a closed end to disassemble the third wheel daily.

본 고안은 이와같은 점을 감안하여 제3륜이 부착된 상태로는 적재함을 적재시켜 물건을 운반하는 용도로 사용할 수도 있고, 유아용 유모기구를 안치시켜 3륜 유모차로도 사용될 수 있으며, 이와같은 제3륜으로 사용중 2륜으로 사용할 경우에는 제3륜을 후속륜에 간단히 절첩하여 제3륜을 후속륜의 측면에 달고 2륜자전거로 사용할 수 있는 3륜자전거를 새로이 안출하는 것이다. 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention can be used for carrying goods by loading a loading box in the state where the third wheel is attached in view of such a point, and can be used as a three-wheeled stroller by placing a baby stroller. In the case of three wheels, the second wheel is simply folded to the next wheel to attach the third wheel to the side of the next wheel, and a new three-wheel bicycle can be used as a two-wheeled bicycle. This will be described in detail based on the accompanying drawings.

좌, 우 본체(3)(3')를 내통상관설한 상, 하 후레임(1)(2)의 일측면에는 제3륜(8)의 후레임(9)이 괘지편(4)으로써 일체로 고정되고 타측면은 후속륜(11)에 돌출구성된 2개의 지지간(5)(5')에 상, 하 네곳에 각각 괘지편(4)으로써 고정하여서되며 상기 상후레임(1)의 작동간(7)에는 스프링(6)이 지지간(5) 하부에 탄설되고, 하후레임(2)의 작동간(7')에는 제2스프링(6')이 후속륜(11)의 적당한 윗부분에 탄설 구성된다. 특히, 좌, 우본체(3)(3')는 상, 하 후레임(1)(2)의 좌, 우에서 각각 "t-1"형으로 관설되므로 상하후레임(1)(2)과 제3륜(8) 일체의 후레임(9)이 항시 좌, 우 유동될 수 있게된다.The frame 9 of the third wheel 8 is integrally fixed by the hanging piece 4 on one side of the upper and lower frames 1 and 2 having the left and right main bodies 3 and 3 'in the usual manner. And the other side is fixed to the two support rods 5, 5 ', which are configured to protrude on the subsequent wheels 11, respectively, by a hanging piece 4 on each of the upper and lower portions, and between the operation of the upper frame 1 (7). The spring 6 is coalesced in the lower portion of the supporting rod 5, and the second spring 6 'is coalesced in a suitable upper portion of the subsequent wheel 11 in the actuating portion 7' of the lower frame 2. . In particular, the left and right main bodies (3) and (3 ') are arranged in the form of "t-1" at the left and right sides of the upper and lower frames (1) and (2), respectively, so that the upper and lower frames (1) and (2) and the third The frame 9 of the wheels 8 can always be flown left and right.

또한, 일측 지지간(5')에는 탄발괘지구(10)를 구성하여 아래후레임(2)을 절첩시 괘지시킨다.In addition, the support frame 5 ′ is configured with a ballistic ruler 10 so that the lower frame 2 is hung when folded.

미설명부호 12는 자전거 본체이다.Reference numeral 12 is a bicycle body.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

본 고안은 3륜자전거로 주행할 경우의 제5(a)도, 제5(b)도와 같이 작동간(7)(7') 각각에 탄설된 스프링(6)(6')에 의하여 후레임(1)(2)의 좌, 우 유동을 제어하게 되며, 2륜자전거로 주행코자하면, 스프링(6)(6')을 제거한뒤 제3륜(8) 일체의 후레임(9)을 후속륜(11)쪽으로 회동시키어 후레임(2) 일측을 지지간(5')의 탄발괘지구(10)에 괘지시킴에 의하여 후속륜(11) 일측에 간단히 절첩 휴대케 된다. (제4도 참조)According to the present invention, when driving in a three-wheeled bicycle, as shown in FIG. 5 (a) and FIG. 5 (b), the frame is installed by springs 6 and 6 'installed in each of the operation sections 7 and 7'. 1) It controls the left and right flow of (2), and when driving with a two-wheeled bicycle, after removing the spring (6) (6 ') and the frame (9) of the third wheel (8) integral wheel (9) 11) by folding the frame (2) side of the support frame (5 ') of the ballistic footing zone 10 of the supporting wheel (5') is simply folded on one side of the subsequent wheel (11). (See Figure 4)

이와같이 본 고안은 종래 알려진 2륜겸용 3륜자전거가 2륜으로 주행코자 할경우 일일히 분해하여 제3륜을 제거한뒤 2륜자전거로 사용케되는 문제점을 개선하여 2륜으로 사용하더라도 제3륜을 제거하지 않고 그대로 후속륜(11)에 절첩시킬수 있게되는 특징이 있는 유용한 고안이다.As such, the present invention improves the problem that the conventionally known two-wheeled three-wheeled bicycle is used as a two-wheeled bicycle after disassembling and removing the third wheel, if the two-wheeled three-wheeled bicycle wants to run with two wheels. It is a useful design that can be folded to the subsequent wheel 11 as it is without removing.
