Abstract

Cette invention concerne une chaussure de femme à double usage, comprenant un ensemble talon pivotant. L'ensemble talon comprend un boîtier et une pièce de talon. Le pivotement est commandé par l'utilisation d'une fermeture à baïonnette à deux étages qui peut être manipulée de façon sélective pour convertir la chaussure entre un style escarpin avec le talon complètement déployé sous la forme d'un talon haut et un autre style de hauteur inférieure avec la pièce de talon dans une position rétractée sous la semelle. L'autre style peut être de type semelle compensée, mocassin, mule ou sandale. L'ensemble talon peut comprendre un ressort qui sollicite la pièce de talon vers la configuration de talon haut complètement déployée, de telle sorte que la pièce de talon dans configuration rétractée passe à configuration de talon haut complètement déployée lorsqu'un bouton de la fermeture à baïonnette est enfoncé.
