Abstract

La présente invention concerne une charnière à aimant qui est pourvue d'un aimant permanent ayant une structure spéciale dans une charnière disposée sur une porte tournante, une fermeture de porte, une adaptation de pièce, une charnière de couvercle et autre, ladite charnière réduisant à un minimum un frottement par l'utilisation de forces d'attraction et de répulsion, étant écologique car il n'est pas utilisé d'huile, permettant à la porte ayant la charnière à aimant attachée à celle-ci d'être ouverte ou fermée selon un angle prédéterminé lorsqu'elle est ouverte à un angle inférieur ou égal à un angle spécifique, et d'être complètement ouverte lorsqu'elle est ouverte à un angle supérieur ou égal à l'angle spécifique. Lorsque la charnière à aimant est appliquée à une charnière, la charnière à aimant comprend : une partie de combinaison fixe ayant une ouverture rectangulaire formée au centre de celle-ci et une pluralité de trous de vis formés autour de l'ouverture ; une partie de combinaison rotative adaptée dans l'ouverture et ayant une pluralité de trous de vis formés sur un côté de celle-ci ; un joint d'articulation fixe et un joint d'articulation de rotation respectivement intégrés aux centres de rotation de la partie de combinaison fixe et de la partie de combinaison de rotation et enroulés sous la forme d'un tube ; un arbre de charnière fixé au joint d'articulation fixe et combiné de façon à pouvoir tourner au joint d'articulation de rotation ; une paire de porte-aimants combinés à l'une des surfaces de contact du joint d'articulation fixe et du joint d'articulation de rotation ; des rainures d'aimant circulaires respectivement formées à une profondeur prédéterminée sur les surfaces correspondantes de la paire de porte-aimants ; un aimant de réglage d'angle dans lequel un aimant du type annulaire est divisé en quatre parties respectives et les pôles (pôle N et pôle S) des surfaces en vis-à-vis des aimants adjacents sont agencés de façon à être différents les uns des autres afin de se combiner, dans la paire de trous d'aimant ; des capuchons d'arbre de charnière dans lesquels l'extrémité supérieure et l'extrémité inférieure du joint d'articulation fixe sont respectivement ajustées par pression.
