Abstract
(EN)
The present invention relates to a movable magnet type bicycle pedal, and a shoe coupling device equipped with a means for preventing attachment of metal powder. More particularly, the present invention relates to a movable magnet type bicycle pedal, and a shoe coupling device equipped with a means for preventing attachment of metal powder, wherein the shoe coupling device and the pedal are respectively provided with a magnet, and are coupled to each other by magnetic force only during pedaling, and, when the pedaling is stopped or the running of a bicycle is stopped, the coupling between the magnets is released through a magnetic separation means and at the same time metal powder attached to a shoe is caused to fallso as to prevent the metal powder from being attached to the shoe.

La présente invention concerne une pédale de bicyclette de type à aimant mobile, et un dispositif de couplage de chaussure équipé d’un moyen pour empêcher la fixation de poudre métallique. Plus particulièrement, la présente invention concerne une pédale de bicyclette de type à aimant mobile, et un dispositif de couplage de chaussure équipé d’un moyen pour empêcher la fixation de poudre métallique, le dispositif de couplage de chaussure et la pédale étant respectivement pourvus d’un aimant, et étant couplés l’un à l’autre par une force magnétique uniquement pendant le pédalage, et, lorsque le pédalage est arrêté ou lorsque le déplacement d’une bicyclette est arrêté, le couplage entre les aimants est libéré par l’intermédiaire d’un moyen de séparation magnétique et, simultanément, une poudre métallique fixée à une chaussure est amenée à tomber de façon à éviter que la poudre métallique soit fixée à la chaussure.

본 발명은 이동 자석식 자전거 페달 및 쇳가루 부착 방지 수단이 구비된 신발 결합장치에 관한 것으로, 더욱 상세하게는 신발 결합장치 및 페달에 각각 자석을 구비하고, 페달링시에만 자력에 의한 결합이 이루어지도록 하고, 페달링을 멈춘 경우, 또는 자전거의 주행을 완료한 경우에는 자석 분리수단을 통해 자석들 간의 결합을 해제함과 동시에 신발에 부착된 쇳가루를 떨어트려 쇳가루가 신발에 부착되는 것을 방지하는 이동 자석식 자전거 페달 및 쇳가루 부착 방지 수단이 구비된 신발 결합장치에 관한 것이다.
