Abstract

Ce perfectionnement concerne plus particulièrement les loqueteaux utilisant des aimants du type Ferrite. Selon l'invention, les deux pièces polaires en contact avec l'aimant sont conformées de manière à transporter le flux magnétique vers deux régions formant des pôles, éloignées l'une de l'autre d'une distance sensiblement supérieure à la longueur de l'aimant, et aptes à venir en contact avec une armature placée sur la partie ouvrante. Cette disposition permet d'étendre le champ d'attraction, malgré la faible longueur des aimants du type utilisé. Application aux loqueteaux servant à la fermeture de porte ou d'autres parties ouvrantes, notamment dans le domaine du mobilier.
