Abstract

L'invention a pour objectif de proposer un fermoir pour un article ornemental, applicable à de multiples types de chevilles ayant différents diamètres, applicable à des articles ornementaux de petite taille tels que des boucles d'oreilles pour oreilles percées, et apte à être fabriqué à coûts modérés. Un tube de guidage présentant une partie conique sur sa surface de paroi interne est installé dans un boîtier ayant une ouverture dans laquelle une cheville est introduite. Des sphères et un élément de pression des sphères comportant un élément de bride sont disposés dans l'espace interne du tube de guidage. L'élément de bride est en contact à sa surface inférieure avec les sphères, et l'élément de pression des sphères est toujours sollicité vers l'ouverture dans laquelle la cheville est introduite. La cheville est maintenue à une position qui se situe dans un cercle formé par les sphères et est située à cette position de diamètre interne d'une partie conique qui correspond à la valeur numérique obtenue par l'expression “diamètre de cheville + diamètre de sphère x 2”.
