자전거 및 자전거형 운동기구의 페달{PEDAL OF BICYCLE AND BICYCLE TYPE EXERCISING MACHINE}PEDAL OF BICYCLE AND BICYCLE TYPE EXERCISING MACHINE}

본 발명은 자전거 및 자전거형 운동기구의 페달에 관한 것으로, 발판과 축을 멈춤 링으로 결합함으로서 각 부품들 간의 결합 상태를 안정적이게 하고 조립 공정을 단순하게 하며, 발판의 축 삽입구 내, 발판과 축 사이에 윤활제 보관 공간을 둠으로써 각 부품들 간의 마찰 부위에 윤활제를 지속적으로 공급할 수 있게 하는 것을 특징으로 한다.The present invention relates to a pedal of a bicycle and a bicycle-type exercise equipment, by combining the footrest and the shaft with a stop ring to stabilize the coupling state between the components and simplify the assembly process, in the shaft insertion hole of the footrest, between the footrest and the shaft By providing a lubricant storage space in the lubricant characterized in that it is possible to continuously supply the lubricant to the friction portion between the parts.

일반적으로 자전거 및 자전거형 운동기구의 페달은 발판의 한 끝에서 그 다른 한 끝까지 관통한 축 삽입구에 한 쪽에서 축을 삽입하고, 그 다른 한 쪽에서 와셔를 축의 끝에 끼우고 축의 끝을 타격하여 축의 끝이 벌어지게 하여 와셔를 고정하거나, 수나사가 있는 축의 끝에 와셔와 너트를 또는 너트만을 체결하여 발판과 축을 결합한다. 또한 페달의 발판과 축 사이에 볼 베어링을 사용한다.Generally, a pedal of a bicycle and a bicycle type exercise machine is constituted such that a shaft is inserted from one end to the shaft insertion hole penetrating from one end of the foot plate to the other end, the washer is fitted to the end of the shaft from the other side, To fix the washer, or engage the foot and shaft by tightening the washer and nut or only the nut at the end of the shaft with male thread. A ball bearing is also used between the pedal foot and the shaft.

기술적 과제Technical Challenge

발판 한 끝에서 그 다른 한 끝까지 관통한 축 삽입구에 한쪽에서 축을 삽입하고, 그 다른 한쪽에서 와셔를 축의 끝에 끼우고 축의 끝을 타격하여 축의 끝이 벌어지게 하여 와셔를 고정하는 방법으로 발판과 축을 결합한 경우에는 축의 끝에 타격을 가할 때 축이 휘어져 발판이 잘 돌지 않을 수 있으며, 수나사가 있는 축의 끝에 와셔와 너트를 또는 너트만을 체결하여 발판과 축을 결합한 경우에는 너트의 조임 정도에 따라 발판이 잘 돌지 않거나 너무 헐거울 수 있으며 풀릴 수도 있다. 어느 방법이든 페달의 발판과 축의 결합 상태가 불안정하고 조립 공정이 복잡하다. 또한 발판과 축 사이에 볼 베어링을 사용함에 따라서 발판이 두꺼울 수밖에 없으며, 페달이 장기간 자연 환경에 노출되면 각 부품들 간의 마찰 부위에 윤활제가 결핍될 수 있다Insert the shaft from one end into the shaft insertion hole that penetrated from one end to the other end, and from the other side, put the washer at the end of the shaft and hit the end of the shaft to open the end of the shaft so that the washer is fixed. In this case, when the end of the shaft is bent, the foot may be bent and the foot may not turn well.In the case where the foot and the shaft are combined with a washer and a nut or only with a nut at the end of the shaft, the foot may not turn well depending on the tightness of the nut. It can be too loose and loose. Either way, the pedal's foot and shaft are unstable and the assembly process is complicated. In addition, the use of ball bearings between the scaffold and the shaft makes the scaffold thick, and if the pedal is exposed to the natural environment for a long time, the friction between the parts may lack lubricant.

과제 해결 수단Challenge solution

이를 해결하고자 본 발명은 발판(1a)과 축(2a)을 멈춤 링(3)으로 결합하거나 축 삽입구(11b) 양쪽에 니들 롤러 베어링(4)을 삽입한 발판(1b)과 축(2b)을 멈춤 링(3)으로 결합한다. 또한 각 부품들 간의 마찰 부위에 지속적으로 공급될 윤활제를 보관하는 공간(21a,21b)을 발판(1a,1b)의 축 삽입구(11a,11b) 내, 발판(1a,1b)과 축(2a,2b) 사이에 둔다.In order to solve this problem, the present invention combines the footrest 1a and the shaft 2a with the stop ring 3 or the footrest 1b and the shaft 2b having the needle roller bearings 4 inserted into both of the shaft insertion holes 11b. Engage with the stop ring (3). The spaces 21a and 21b for storing the lubricant to be continuously supplied to the friction portions between the respective components are inserted into the shaft insertion holes 11a and 11b of the foot plates 1a and 1b and between the foot plates 1a and 1b and the shafts 2a and 2b, 2b).

발명의 효과Effects of the Invention

이로써 본 발명은 발판(1a,1b)과 축(2a,2b)의 결합 상태를 보다 안정적이게 하고, 조립 공정을 단순하게 하며, 발판(1b)과 축(2b) 사이에 볼 베어링을 사용할 때 보다 발판(1b)을 얇게 만들 수 있게 하고, 각 부품들 간의 마찰 부위에 윤활제를 지속적으로 공급을 할 수 있게 한다.As a result, the present invention makes the coupling state of the footrests 1a and 1b and the shafts 2a and 2b more stable, simplifies the assembly process, and is more effective than using a ball bearing between the footrests 1b and the shafts 2b. It is possible to make the footrest 1b thin, and to continuously supply lubricant to the friction part between the parts.
