Abstract

La présente invention a pour objet de fournir un dispositif de porte d'ascenseur qui peut empêcher de manière efficace un dispositif de protection contre la sortie de sortir d'une gorge de guidage par dispersion et réception d'une charge appliquée en utilisant deux cliquets qui présentent des effets de prévention de sortie différents, c'est-à-dire un premier cliquet qui bute et vient en prise contre la première surface latérale de la gorge de guidage, et un deuxième cliquet qui bute contre la deuxième surface latérale de la gorge de guidage du fait de la déformation d'un montant de porte, et qui se déforme plastiquement de manière à venir en prise contre la deuxième surface latérale. L'invention concerne un dispositif de porte d'ascenseur comprenant une pluralité de cliquets, un premier cliquet et un second cliquet, qui sont disposés de manière à faire saillie au niveau d'un côté ou des deux côtés de la direction de la largeur d'un montant de porte et qui coulissent dans le sens de la largeur dans une rainure de guidage à l'unisson avec le montant de porte et qui peuvent chacun indépendamment se déformer en association avec la déformation du montant de porte. Le premier cliquet vient en butée contre et vient en prise contre la première surface latérale de la rainure de guidage en conséquence de son déplacement d'une position normale par une charge qui est générée quand une porte coulissante est poussée à partir d'une direction principalement verticale par rapport à la direction de la largeur. Le deuxième cliquet vient en butée contre la deuxième surface latérale de la rainure de guidage en raison de la déformation du montant de porte, et se déforme de manière plastique pour venir en prise contre la deuxième surface latérale.
