본 고안은 자전거의 사용시 좌우의 페달에 의하여 회전되는 중앙부위의 체인휠에 대하여 감력판을 취착하여, 그 주면에 형성한 고정판에 좌우측 페달봉의 내측의 연장단부를 고정되게 하므로서, 자전거의 사용시 소모되는 밟는 힘을 감축되게 함과 동시에 특히 경사진 언덕길을 오를 때에 용이하게 주행될 수 있게한 자전거용 감인력 체인휠 장치에 관한 것이다.According to the present invention, a shock absorbing plate is attached to a chain wheel of a central part rotated by left and right pedals when the bicycle is used, and the extension end of the left and right pedal rods is fixed to a fixed plate formed on the main surface thereof. In particular, the present invention relates to a bicycle-powered chain wheel device for a bicycle, which reduces the stepping force and, in particular, makes it easy to travel when climbing a sloped hill.

종래의 자전거에 있어서, 그 양측의 페달봉은 체인휠판의 회전축의 양측에 단순하게 축착되게 한 것이어서, 체인휠에 걸려 있는 후륜측의 체인을 돌리게 하였던 단순한 구조이어서, 사용자의 밟는 힘은 1차적으로 작용할뿐, 체인휠의 측 자체를 효과적으로 회전되게 할 수 없어서 특히 경사진 언덕 등을 오를때는 사용자의 밟는 힘이 매우 많이 소비되었던 것이고, 또한 변속기어를 장착하여 속도를 조절하거나, 주행에 소비되는 힘을 조절하는 경우도 있으나 이는 주행중의 기어조작으로 사고의 위험이 따랐고, 장치의 복잡성으로 고장이 잦은 결점이 있었다.In the conventional bicycle, the pedal rods on both sides are simply fixed to both sides of the rotation shaft of the chain wheel plate, and thus the simple structure used to rotate the chain on the rear wheel side hanging on the chain wheel, so that the user's stepping force will act primarily. In addition, the side of the chain wheel itself could not be effectively rotated, especially when climbing slopes, etc., the user's stepping force was very much consumed. Also, the gear was mounted to adjust the speed or to drive. In some cases, this was accompanied by the risk of accidents due to the operation of gears while driving, and the defects were frequent due to the complexity of the device.

본 고안은 자전거용 체인휠 장치에 관하여, 전기한 바와같은 결점을 제거코져 고안한 것으로, 본 고안의 요지를 도면의 실시예에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to remove the drawbacks as described above with respect to the bicycle chainwheel device for bicycles, and the subject matter of the present invention will be described in detail by the embodiments of the drawings.

자전거의 체인휠(1)에 있어서, 그 회전축(2)에 대하여 보호판(3)과의 사이에 감력판(4)을 볼트넛트(5)(5')등으로 결합시키되, 감력판(4)의 주면에는 두쌍의 고정돌판(6)(6') 및 (7)(7')을 형성하고, 일측 페달봉(8)은 그 축공(9)을 회전축(2)에 축착하되, 페달봉(8)의 내측 선단을 연장한 연장단부(10)를 형성하여 이를 전기한 고정돌판(6)(6')에 고정되게 하고, 타측 페달봉(11)은 회전축(2)에 축착하되, 회전축(2)에 연동간(12)을 축착하여, 연동간(12)의 선단부를 전기 고정돌판(7)(7')에 고정되게 한 구성이다.In the chain wheel (1) of the bicycle, the damping plate (4) is coupled to the rotary shaft (2) with the protective plate (3) by bolt nuts (5) (5 ') or the like. On the main surface of the two pairs of fixed stone plate (6) (6 ') and (7) (7'), one side of the pedal rod (8) is the shaft hole (9) on the rotary shaft (2), but the pedal rod ( 8 to form an extension end portion 10 extending the inner end of the fixed end 6 to be fixed to the fixed stone plate (6) (6 '), and the other pedal rod 11 is fixed to the rotary shaft (2), but the rotary shaft ( The interlocking rod 12 is condensed in 2), and the front end of the interlocking rod 12 is fixed to the electric fixing stones 7 and 7 '.

미설명부호 13, 13′는 결합공, 14는 체인, 15, 15′는 페달, 16은 축수부, 17은 차체이다.Reference numerals 13 and 13 'are engagement holes, 14 are chains, 15 and 15' are pedals, 16 are bearing parts, and 17 are body parts.

이와같이된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above is as follows.

통상의 자전가 차체(17)의 축수부(16)에 본 고안에 의한 체인휠(1)의 회전축 (2)을 유삽하여 설착하되, 체인휠(1)의 회전축(2)에 감력판(4)을 설착하여 그 주면부에 형성한 고정돌판(6)(6')에 일측 페달봉(8)의 내측 길이를 연장하여 형성한 연장단부 (10)를 고정되게 한 것이고, 타측 페달봉(11)은 회전축(2)을 통하여 결합된 연동간 (12)의 단부가 고정돌판(7)(7')에 고정되게 한 것이어서, 자전거의 사용시 좌우 양쪽 페달(15)(15')을 밟으면 그 밟는 힘에 의하여 일측의 페달봉(8)의 연장단부(10)의 길이의 타측의 페달봉(11)의 연동간(12)의 길이만큼의 회전축(2)을 돌리는 반대방향의 회동력이 증가되므로, 페달을 밟은 인력이 절감되는 것이므로 도로상의 통상의 사용에도 수월하게 주행할 수 있고, 특히 경사진 언덕길을 오를때는 그 효과가 더욱 현저한 것이어서, 용이하게 오를 수 잇는 것이다.The rotating shaft 2 of the chain wheel 1 according to the present invention is installed by inserting it into the bearing portion 16 of the ordinary rotating vehicle body 17, but the pressure plate 4 is attached to the rotating shaft 2 of the chain wheel 1. The extension end portion 10 formed by extending the inner length of one pedal rod 8 to the fixed stone plate 6, 6 'formed on the main surface portion thereof and fixed to the other side pedal rod 11; The end portion of the interlocking rod 12 coupled through the rotation shaft 2 is fixed to the fixed stone plates 7 and 7 ', and when the bicycle is used, the stepping force is applied when the pedals 15 and 15' are pressed. Since the rotational force in the opposite direction of turning the rotary shaft 2 by the length of the interlocking portion 12 of the pedal rod 11 on the other side of the length of the extension end 10 of the pedal rod 8 on one side is increased, Since the manpower that is pedaled is reduced, it can be easily driven even in normal use on the road, and the effect is more remarkable, especially when climbing a sloped hill. It can climb.

본 고안의 실시에 있어서, 감력판(4)의 직경이나 페달봉(8)(11)의 연장단부 (10) 및 연동간(12)의 길이 등은 자전거의 대소 규격이나 화물 운반용 또는 대소인용 등의 다양한 용도에 따라 그 설계를 임의로 변경할 수 있어서, 다양한 규격으로 실시할 수 있는 것이고, 또한 본 고안은 통상의 자전거의 축수부(16)에 대하여, 용이하게 설착할 수 있으므로, 널리 보급될 수 있는 효과가 있는 것이다.In the practice of the present invention, the diameter of the shock absorbing plate 4, the length of the extension end 10 and the interlocking rod 12 of the pedal rods 8, 11, etc., is the size of the bike, the size of the cargo, The design can be arbitrarily changed according to various uses of the present invention, which can be carried out in various standards, and the present invention can be easily installed on the bearing part 16 of a conventional bicycle, and thus can be widely used. It works.
