Abstract

La présente invention se rapporte à un banc pliable du type à retour automatique. Le banc pliable du type à retour automatique comprend : une partie siège ; un support qui supporte la partie siège ; une partie pivotante qui peut tourner entre un état utilisable, dans lequel la partie siège peut être placée sur le support, et un état plié, dans lequel la partie siège est pliée vers le haut ; une partie d'entraînement principale qui maintient l'état plié de la partie siège et stocke une force de rappel lorsque la partie siège est mise en rotation par une force externe pour passer à l'état utilisable ; et une partie d'entraînement auxiliaire qui fait d'abord tourner la partie siège par une force de rappel automatique pour aider à la rotation de la partie siège jusqu'à l'état pliable par la force de rappel stockée dans la partie d'entraînement principale. La partie pivotante est couplée à un arbre disposé sur le support de telle sorte qu'un côté du centre de l'arbre puisse pivoter. Une extrémité de la partie pivotante est fixée à la partie siège, et l'autre extrémité comprend une came de rotation raccordée à la partie d'entraînement principale. La partie d'entraînement principale a une extrémité qui est utilisée comme vérin pneumatique et une autre extrémité qui est utilisée comme vérin hydraulique, lesdits vérins étant respectivement supportés sur l'autre extrémité de la came de rotation et un côté du support. La partie d'entraînement auxiliaire utilise l'une et l'autre de ses extrémités comme ressorts hélicoïdaux qui sont respectivement supportés sur l'autre extrémité de la came de rotation et l'autre côté du support. Ainsi, puisque la partie siège est automatiquement pliée en passant de l'état utilisable à l'état plié, le banc peut être installé et utilisé de manière efficace. De même, le pliage de la partie siège peut être effectué de manière stable et facilement au moyen de la partie d'entraînement principale et de la partie d'entraînement auxiliaire.
