Abstract

L'invention concerne un module coulissant, et plus particulièrement un module coulissant dans lequel deux rails mobiles sont disposés dans le sens de coulissement du coulisseau qui se déplace vers le haut ou vers le bas par le biais d'une charnière ménagée dans un téléphone portatif de type coulissant, un téléphone intelligent ou analogue. Les deux rails mobiles sont inclinés dans des directions opposées, c'est-à-dire vers la gauche et vers la droite, respectivement, d'un point de départ du coulissement au point intermédiaire du coulissement, puis inclinés de nouveau dans l'autre direction, à l'opposé du point intermédiaire du coulissement, si bien que le point de fin de course du coulissement se situe sur la même ligne que le point de départ du coulissement.
