Abstract

L'invention concerne une paire de lunettes comprenant plusieurs pièces comme en particulier des verres de lunettes (2), des branches de lunettes (3), un pont de lunettes (4), un encadrement des verres, des éléments décoratifs (5) ou similaires. En tant que perfectionnement avantageux, au moins deux pièces peuvent être assemblées ou sont assemblées, en particulier de manière amovible, au moyen d'un accouplement à emboîtement (6), au moins une pièce comprenant en au moins une zone de raccordement respectivement une paire de languettes élastiques (11) écartées l'une de l'autre, en particulier de manière parallèle, qui comportent à leur extrémité longitudinale libre une saillie (17) orientée à l'opposé de la languette élastique voisine (11). Pour permettre un assemblage libérable de ladite pièce avec une autre pièce, cette dernière comporte directement ou indirectement au moins une ou plusieurs ouvertures de passage (19), la distance maximale entre les surfaces extérieures orientées à l'opposé l'une de l'autre des deux saillies (17) sur la paire de languettes élastiques (11), lorsque ces dernières sont à l'état non sollicité, étant supérieure à une largeur de l'ouverture de passage (19).
