본 고안은 곡선형의 체대 전후에 직경이 작고 큰 차륜을 축착하여 직경이 큰 후차륜에 동력전달장치를 장착하므로서 제작시 조립작업이 간편할 뿐 아니라 페달을 밟으면 직경이 큰 후차륜의 측이 회전되어 동력이 직접 전달되므로 인력 소모를 줄임과 동시에 적은 인력으로 속도를 낼수 있게한 자전거에 관한 것이다.The present invention is equipped with a power transmission device on the large diameter rear wheels by condensing the large diameter wheels before and after the curved body, so that the assembly work is easy in manufacturing and the side of the large rear wheel rotates when the pedal is pressed. As the power is directly transmitted, it reduces the manpower consumption and at the same time speeds the bicycle with less manpower.

종래의 일반적인 자전거는 전후 차륜의 직경이 동일하고 동력전달은 폐달을 밟으면 폐달축상의 기어와 체인에 의하여 연동되는 후차륜과 동일축상의 기어가 회전과 동시에 후차륜이 회전 되면서 전진되는 것인데, 전진을 하기 위한 출발 동작시는 많은 인력이 소요될 뿐 아니라 동력전달을 폐달측의 기어와 축의 프라이 휘일을 내부에 장착한 기어를 체인에 의하여 전달되게 한 것이므로 구조적으로 복잡하여 조립공정이 번거러운 반면에 조립 역시 까다로워서 많은 인력과 시간을 소모하고 체인에 의한 동력 전달시에는 오일이 밖으로 누출되는 부분이 많아 옷을 더럽히는 등의 결점이 있었다.Conventional bicycles have the same diameter of the front and rear wheels, and power transmission is when the rear wheel is rotated and the rear wheel is rotated at the same time as the rear wheel linked by the gear and chain on the closed moon shaft is advanced. In the starting operation, it takes not only a lot of manpower but also the power transmission to the gears with the gears on the closed side and the fry wheels of the shafts transferred by the chain, which is structurally complicated and the assembly process is cumbersome. It consumed a lot of manpower and time, and when the power was transmitted by the chain, the oil leaked out a lot, and the clothes were dirty.

본 고안은 자전거에 관하여 상기한 바와 같은 종래의 제반 문제점을 해소하고져 안출한 것으로서, 그 요지를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made to solve the conventional problems as described above with respect to the bicycle, the gist will be described in detail by the accompanying drawings as follows.

핸들(1)하방에 아동용 의자를 겸한 바구니 재치틀(2)을 착설하고, 체대(3)를 곡선형으로 형성하여 전후에 직경이 작고 큰 전차륜(4)과 후차륜(5)을 축착하며, 체대(3)의 하측단부에 고정환체(6)(6')를 고착하여 편심공(7)(7')상의 베어링(8)(8')에 삽착된 회전축(9)상에는 베어링(10)(10')으로 축삽되고 양쪽에서 나합되게한 프라이휘일(11)(11')을 축삽하되, 회전축(9)의 요홈(9')과 원통체(12)의 삽공(12') 직하방의 요홈(12')간에 괘구(13)를 삽설하여 코일스프링(14)을 탄착하고, 원통체(12)의 일측에는 요구(15)(15')를 형성하여 압구(16)(16')를 삽착후 하부에 탄편(17)(17')을 탄착시켜서 입구(16)(16')의 돌출단부를 프리이휘일(11)(11')내면 일측의 일방으로 향한 거치형의 잇발(18)(18')과 치합되게 하며, 양쪽의 고정환체(6)(6') 외측에는 베어링(19)(19')의 내연부를 나합하고, 외연부에는 회전축(9)양단의 소기어(20)(20')와 치합된 내면기어(21)(21')를 형성하고 전후 반대로 폐달(22)(22')을 착설한 회전환체(23)(23')를 나합하여서 된 것이다.Under the handle (1), a basket mounting frame (2) serving as a chair for children is installed, and the body (3) is formed in a curved shape, and the front and rear wheels (5) and the rear wheels (5) are small and have a small diameter before and after The fixed ring 6, 6 'is fixed to the lower end of the body 3 and the bearing 10 is mounted on the rotating shaft 9 inserted into the bearings 8, 8' on the eccentric holes 7, 7 '. 10 ') and insert the primary wheels 11 and 11' which are screwed on both sides, and are directly below the groove 9 'of the rotating shaft 9 and the insertion hole 12' of the cylindrical body 12 '. Inserting the ruler 13 between the grooves 12 'to secure the coil springs 14, and on one side of the cylindrical body 12, requests 15 and 15' are formed to form the inlet 16 and 16 '. After insertion, the pieces 17 and 17 'are attached to the lower part so that the protruding ends of the inlets 16 and 16' are oriented toward one side of the inner side of the free wheel 11 and 11 '. The inner edges of the bearings (19) and (19 ') on the outside of the fixed ring (6) (6') on both sides, Rotating ring 23 formed with inner gears 21 and 21 'engaged with small gears 20 and 20' at both ends of the rotating shaft 9, and on the opposite side of the rotating shafts 22 and 22 '. 23 ').

도면중 미설명 부호 24는 안장, 25,25' 및 26,26'는 스포오크, 27,27' 공정공, 28은 삽공, 29는 압봉이다.In the drawings, reference numeral 24 denotes a saddle, 25, 25 'and 26, 26' are spokes, 27, 27 'process workers, 28 are insertion holes, and 29 are push rods.

이와같이 구성된 본 고안은 핸들(1) 하방의 재치틀(2)에 바구니를 재치하여 바구니속에 물건들을 수용하여 운반하거나 어린이를 앉힐수 있으며, 운전자가 핸들(1)을 잡은 상태로 안장(24)에 앉게되면 상체가 앞쪽으로 기울어 지게 되고 이렇게 안정된 상태로 폐달(22)(22')을 밟아, 회전시키게 되면 회전환체(23)(23')는 체대(3)의 하측 단부에 고정된 고정환체(6)(6')의 베어링(19)(19')에 의지된 채 베어링의 원활한 굴림작동에 의하여 회전된다.The present invention configured as described above allows the basket to be placed on the mounting frame 2 below the handle 1 to accommodate and carry items in the basket or to sit a child, while the driver holds the handle 1 to the saddle 24. When seated, the upper body is inclined forward, and when the pedal moon 22 (22 ') is stepped in such a stable state and rotated, the rotation ring 23, 23' is fixed to the lower end of the body 3 (6) It is rotated by the smooth rolling operation of the bearing while being relied on the bearings 19 and 19 'of 6'.

따라서, 회전환체(23)(23') 내면기어(21)(21')에 치합된 소기어(20)(20')의 증속된 회전으로 회전축(9)이 회전될 때 회전축(9)의 요홈(9')에서 코일스프링(14)에 탄지된 괘구(13)가 원통체(12)의 요홈(12")에 삽설된 상태에서 원통체(12)가 동시 회전되며, 원통체(12)의 회전시에 일측의 요구(15)(15')내에서 탄편(17)(17')의 탄력으로 탄출된 압구(16)(16')의 돌출 단부가 프리이휘일(11)(11')의 일방으로 향한 거치형 잇발(18)(18')과 치합상태에서 같이 회전되므로 프리이휘일(11)(11')과 스포오크(27)(27')로 결속되어 원형을 유지하는 후차륜(5)이 회전됨과 동시에 전진되고, 전진에 의한 가속화된 탄력으로 폐달(22)(22')을 밟고 있거나 폐달(22)(22')을 반대로 회전시킬때는 프리이휘일(11)(11')의 내면기어(21)(21')가 반대 회전시에 압구(15)(15')를 누르면서 공회전되는 것이다.Accordingly, the rotary shaft 9 when the rotary shaft 9 is rotated by the accelerated rotation of the small gears 20 and 20 'engaged with the inner gears 21 and 21' of the rotating ring 23, 23 '. The cylindrical body 12 is simultaneously rotated in the state in which the ruler 13 supported by the coil spring 14 in the groove 9 'is inserted into the groove 12 "of the cylindrical body 12, and the cylindrical body 12 ), The protruding end of the pressure port 16, 16 'is elastically projected by the elastic pieces 17, 17' within one side of the request 15, 15 'at the time of rotation of the pre-wheel 11, 11'. The rear wheel (1) (11 ') and the spokes (27', 27 ') that are rotated together in the state of engagement with the stationary tooth (18) (18') toward one side of the rear wheel (1) 5) is rotated and advanced at the same time, and when the pedal moon 22 (22 ') is stepped on by the accelerated elasticity by the forward movement or when the lung moon 22 (22') is rotated in reverse, the free wheel 11 (11 ') When the inner gears 21 and 21 'are rotated in opposite directions, the inner gears 21 and 21' are idle while pressing the pressure balls 15 and 15 '.

그리고, 후차륜(5)을 축착하여 회전축(9)과 원통체(12)를 고정시킬 때는 후차륜(5) 중앙의 프리이휘일(11)(11')을 회전축(9)상에서 한바퀴 회동시키면 회동 도중에 회전축(9)의 요홈(9')에 탄착된 괘구(13)가 원통체(12)의 요홈(12") 위치에서 코일스프링(14)의 탄발력으로 돌출되어 괘지 고정되는 것이며, 반대로 분리할 시에는 프리이휘일(11)(11')의 삽공(28)과 원통체(12)의 삽공(12')을 일치시켜 제4도의 도시와 같이 압봉(29)으로 눌린후 후차륜(5)과 같이 프리이휘일(11)(11')을 회동시키면 괘구(13)는 괘지 상태를 해제하는 것이다.Then, when the rear wheel 5 is fixed and the rotary shaft 9 and the cylindrical body 12 are fixed, the pre-wheel 11, 11 ′ in the center of the rear wheel 5 is rotated once on the rotary shaft 9 to rotate. The ruler 13, which is in contact with the groove 9 ′ of the rotating shaft 9, is projected by the elastic force of the coil spring 14 at the groove 12 ″ of the cylindrical body 12 and fixed to the ruler. At the time of insertion, the insertion hole 28 of the free wheel 11, 11 'and the insertion hole 12' of the cylindrical body 12 coincide with each other and are pressed by the push rod 29 as shown in FIG. As described above, when the free wheels 11 and 11 'are rotated, the ruler 13 releases the ruled state.

본 고안은 상기와 같이 동력전달장치를 후차륜(5) 회전 축 (9)에 같이 장착함으로서, 구조를 간편하게 하여 조립작업이 용이한 반면에 페달의 회전으로 발생하는 동력전달을 후차륜에 직접 전달되게 한 것이므로 출발동작으로부터 주행시에는 인력의 소모를 최대한으로 줄일수 있으며 체인을 사용함이 없어 오일의 누출이 방지 되므로 의류를 더럽히는 일이 없는등의 효과가 있다.The present invention is equipped with a power transmission device on the rear wheel (5) rotation shaft (9) as described above, while simplifying the structure and easy assembly work, while the power transmission generated by the rotation of the pedal directly transfers to the rear wheel. Since it is possible to reduce the consumption of manpower as much as possible when driving from the starting operation, and there is no use of the chain, oil leakage is prevented, so there is no effect of dirtying clothes.
