Abstract

La présente invention a trait à une charnière pivotante multicouche destinée à un terminal portatif, et plus particulièrement à une charnière pivotante multicouche destinée à un terminal portatif qui fait tourner un corps auxiliaire relié à la section supérieure d'un corps principal dans la direction horizontale par rapport à ce corps principal afin d'ouvrir ou de fermer ledit terminal portatif. Cette charnière pivotante multicouche destinée à un terminal portatif comprend : un boîtier qui est monté sur le corps principal du terminal portatif ; une partie rotative qui est reliée rotative à ce boîtier et qui comprend une came supérieure et une came inférieure empilées verticalement à l'emplacement de la section inférieure de la partie rotative, ladite partie rotative étant montée sur le corps auxiliaire qui tourne par rapport au corps principal ; une coulisse qui est insérée dans ledit boîtier et qui est en contact avec la came supérieure ou la came inférieure ; et un ressort qui est introduit dans ledit boîtier afin de soutenir élastiquement la coulisse dans une direction de la partie rotative. Lorsque la partie rotative tourne, son angle de rotation au moment où elle tourne automatiquement en raison de la force de rappel élastique du ressort comprimé est plus grand que son angle de rotation au moment où elle comprime le ressort.
