Abstract

La présente invention concerne un dispositif d'une structure de canapé comprenant une base (1), un mécanisme de liaison (2) et deux structures de déploiement (3) disposées symétriquement au niveau de la base (1). Le mécanisme de liaison (2) comprend une première tige de liaison (21) et une seconde tige de liaison (22). Deux extrémités de la première tige de liaison (21) sont respectivement reliées aux deux structures de déploiement (3). Deux extrémités de la seconde tige de liaison (22) sont elles aussi respectivement reliées aux deux structures de déploiement (3). Un premier connecteur (211) est disposé sur une partie centrale de la première tige de liaison (21) et un second connecteur (221) est disposé sur une partie centrale de la seconde tige de liaison (22). Le premier connecteur (211) et le second connecteur (221) sont reliés à un élément d'entraînement et sont entraînés par l'élément d'entraînement pour se déplacer l'un par rapport à l'autre, de façon à amener les deux structures de déploiement (3) à se déployer ou à se rétracter. Le dispositif de la structure de canapé permet d'exécuter un mouvement harmonieux et silencieux pendant la conversion de la position d'un canapé, d'éviter des changements soudains de vitesse, et d'empêcher le dispositif de la structure de se coincer ou d'être secoué.
