Abstract

L'invention concerne un dispositif d'ouverture et de fermeture de type à poussée 2 qui peut présenter une fonctionnalité de mise en tampon suffisante par rapport à la rotation d'un couvercle dans la direction de fermeture. Le dispositif d'ouverture et de fermeture de type à poussée 2 comprend : un cadre de support 10 qui définit une ouverture d'entrée 12 ; un couvercle 20 qui ouvre et ferme l'ouverture d'entrée 12, et dont l'extrémité supérieure est supportée sur le cadre de support 10 de manière à pouvoir tourner autour de l'axe de rotation horizontal ; un poids 30 qui est fixé sur le côté arrière du couvercle 20 et qui applique un moment de rotation au niveau du couvercle 20 dans la direction de fermeture ; et un mécanisme d'amortisseur 40 qui supprime la rotation du couvercle 20 dans la direction de fermeture. Le mécanisme d'amortisseur 40 comporte des premier et deuxième éléments de came 41, 42 et un amortisseur linéaire 43 qui sont disposés sur l'axe de rotation L. Le premier élément de came 41 est fixé sur le cadre de support 10 de manière à ne pas pouvoir tourner l'un par rapport à l'autre et à ne pas pouvoir se déplacer dans la direction axiale, et le deuxième élément de came 42 est supporté par le couvercle 20 de façon à ne pas pouvoir tourner l'un par rapport à l'autre. Le deuxième élément de came 42 se déplace dans la direction axiale avec la rotation du couvercle 20. L'amortisseur linéaire 43 supprime le mouvement du deuxième élément de came 42 dans la direction axiale en raison de la rotation du couvercle 20 dans la direction de fermeture.
