Abstract

PURPOSE: An interlocking device of a bicycle is provided to dissolve a problem of oil staining clothes in case of without additional cover at a chain and in case the chain is frequently separated. CONSTITUTION: Interlocking bases(11,11') are arranged one by one in a mutually counter direction of rear wheel and one side of interlocking bases and links(12,12') are connected with rivets(13,13'). Distance from a center of a rear wheel shaft(3) to a center of the rivets(13,13') of left and right sides is to be equal. Moreover, at right and left sides of a crank axle(2), in a middle of cranks(5,5'), sills(6,6') are formed to connect other sides of the links(12,12'). And a distance from the center of crank shaft to a center of left and right sills of crank is equal to a distance from a center of rear axle to left and right rivets. Since a rotational locus of left and right sills(6,6') of crank rotating by pedals(4,4') and of the rives of interlocking base of rear axle is equaled, left and right sills (6,6') of crank and left and right interlocking bases are connected by the links. Accordingly, with pedals(4,4'), the cranks(5,5') rotate and the left and right links connected to the sills rotate together for rotating the interlocking bases(11,11') of rear axle as to advance the rear wheel axle.

Description

자전거 연동장치Bicycle linkage

본 발명은 자전거의 연동장치에 관한 것이다.The present invention relates to a bicycle interlock device.

종래의 자전거 연동장치는 페달로 스프로킷을 돌려서 체인이 뒷바퀴축에 결합된 스프로킷을 돌려주는 구조였다.Conventional bicycle linkage was a structure that rotates the sprocket connected to the rear wheel shaft by rotating the sprocket with a pedal.

그러나, 스프로킷과 체인으로 구동되는 종래의 자전거는 체인이 스프로킷에서 자주 이탈되고, 체인에 별도의 커버가 없는 경우에는 옷등에 체인의 기름이 묻는 폐단이 있었다.However, in a conventional bicycle driven by a sprocket and a chain, when the chain is frequently detached from the sprocket, and there is no separate cover on the chain, there is a closed end where the oil of the chain gets on the clothes and the like.

본 발명은 위와 같은 폐단을 해소시키기 위하여 종래에 자전거 연동장치로 사용되던 스프로킷과 체인대신에 페달에 의하여 회전하는 크랭크와 뒷바퀴축의 좌우에 설치된 연동대를 링크로 연결시켜 뒷바퀴가 전진하도록 구성한 것이다.The present invention is to configure the rear wheel to move forward by connecting the linkage installed on the left and right of the rear crank and the rear crank rotated by the pedal instead of the sprocket and chain used in the prior art as a bicycle linkage device to eliminate the above-mentioned end.

즉, 본 발명은 스프로킷 대신에 뒷바퀴축의 좌우측에 연동대를 상호반대 방향으로 하나씩 설치하며, 각각의 연동대와 링크의 한쪽을 리벳으로 연결시키고, 페달이 결합된 크랭크의 중간에 형성된 좌우턱에 링크의 한쪽을 연결시킴으로써, 페달에 의해 크랭크가 회전할 때 링크가 회동하면서 뒷바퀴축의 좌우에 설치된 연동대가 회전되어 뒷바퀴가 전진하는 구조이다.That is, in the present invention, instead of the sprocket, the linkages are installed on the left and right sides of the rear wheel shaft one by one in opposite directions, and each linkage and one side of the link are connected by rivets, and the links are formed on the left and right jaws formed in the middle of the crank to which the pedal is coupled. By connecting one side of the, when the crank is rotated by the pedal, the linkage is rotated while the linkages installed on the left and right of the rear wheel shaft is rotated to move the rear wheel forward.

제2도는 본 발명의 단면도.2 is a cross-sectional view of the present invention.

본 발명의 구체적인 구성과 작용을 첨부된 일실시예로서의 도면을 참조하여 상세히 설명하면 다음과 같다.The detailed configuration and operation of the present invention will be described in detail with reference to the accompanying drawings as an embodiment.

도 1은 본 발명의 측면도이며, 도 2는 본 발명의 단면도이다.1 is a side view of the present invention, Figure 2 is a cross-sectional view of the present invention.

본 발명의 종래의 스프로킷 대신에 연동대(11,11')를 뒷바퀴축의 좌우측에 상호 반대방향으로 하나씩 설치하여 각각의 연동대(11,11')와 링크(12,12')의 한쪽을 리벳(13,13')으로 연결시키고 뒷바퀴축(3)의 중심으로부터 좌우측 리벳(13,13')의중심까지의 거리가 동일하게 한다.Instead of the conventional sprocket of the present invention, the linkages 11 and 11 'are installed on the left and right sides of the rear wheel shaft one by one in opposite directions to rivet one of each linkage 11 and 11' and the link 12 and 12 '. (13, 13 ') and the distance from the center of the rear wheel shaft (3) to the center of the left and right rivets (13, 13') is equal.

또한 크랭크축(2)의 좌우로 크랭크(5,5')의 중간에 턱(6,6')을 형성하여 링크(12,12')의 다른 한쪽을 연결시키며 크랭크축(2)의 중심으로부터 링크가 연결된 크랭크좌우턱(6,6')의 중심까지의 거리와 뒷바퀴축(3)의 중심으로부터 좌우리벳(13,13')의 중심까지의 거리가 동일하게 한다.In addition, the jaws 6, 6 'are formed in the middle of the cranks 5, 5' to the left and right of the crank shaft 2 to connect the other side of the links 12, 12 'and from the center of the crank shaft 2 The distance from the center of the rear wheel shaft 3 to the center of the right and left rivets 13 and 13 'is equal to the center of the crank left and right jaws 6 and 6' to which the link is connected.

페달(4,4')에 의하여 회전하는 크랭크의 좌우턱(6,6')과 뒷바퀴축의 좌우에 설치된 연동대의 리벳(13,13')의 회전 궤적이 동일하므로, 크랭크 좌우의 턱(6,6')과 뒷바퀴축의 좌우 연동대(11,11')를 각각 링크(12,12')로 연결시키면 종래의 자전거에 있어서의 스프로킷과 체인을 대신할 수가 있다.Since the rotation trajectories of the right and left jaws 6 and 6 'of the crank rotated by the pedals 4 and 4' and the rivets 13 and 13 'of the linkages installed on the left and right of the rear wheel shaft are the same, the jaws 6 and 6 of the crank left and right are the same. 6 ') and the left and right linkages 11 and 11' of the rear wheel shaft are connected to the links 12 and 12 ', respectively, to replace the sprocket and the chain in the conventional bicycle.

따라서, 페달(4,4')에 의하여 크랭크(5,5')가 회전하면서, 크랭크의 턱(6,6')에 연결된 좌우의 링크(12,12')가 회동하며 뒷바퀴축(3)의 좌우측에 설치된 연동대(11,11')가 회전하여 뒷바퀴가 전진하게 된다.Accordingly, while the cranks 5 and 5 'are rotated by the pedals 4 and 4', the left and right links 12 and 12 'connected to the jaws 6 and 6' of the crank rotate and the rear wheel shaft 3 is rotated. Interlocks (11, 11 ') installed on the left and right sides of the rear wheel is advanced.

그리고, 본 발명에 의하여 대체되는 그 이외의 부분 예를 들어, 뒷바퀴의 역회전 방지를 위하여 래치트기어를 뒷바퀴축에 결합시킨다든가, 앞바퀴와 뒷바퀴에 브래이크를 설치하는 것등은 종래의 자전거와 동일하다.And other parts replaced by the present invention, for example, to engage the ratchet gear to the rear wheel shaft to prevent the reverse rotation of the rear wheel, or to install the brakes on the front wheel and the rear wheel, and the same as the conventional bicycle Do.

종래의 자전거에서 사용되던 스프로킷과 체인을 연동대와 링크로 대체 시킴으로써, 체인이 스프로킷에서 자주 이탈하는 폐단이 없으며, 생산공정이 보다 더 단순화되고, 생산비용도 크게 절감된다.By replacing the sprocket and chain used in the conventional bicycle with the linkage and the link, there is no closing end of the chain from the sprocket frequently, the production process is more simplified and the production cost is greatly reduced.

또한 페달의 회전수와 뒷바퀴의 회전수가 일치하므로, 적은 힘만으로도 주행이 가능하여 경사진 도로에서도 별도의 기어가 필요없으며, 과속으로 인한 위험발생이 없다.In addition, since the number of rotations of the pedal and the number of rotations of the rear wheels coincide with each other, it is possible to drive with only a small amount of power, so there is no need for a separate gear even on a sloping road and there is no danger of overspeed.
