Abstract

L'invention concerne un tablier de sécurité pour train. Ce tablier de sécurité, qui comprend un élément d'interconnexion de porte exploitable selon la position d'ouverture ou de fermeture de la porte, convertit le mouvement horizontal de la porte en mouvement vertical; un premier élément de guidage relié à la porte et monté de part et d'autre du cadre de la porte pour élever/abaisser la porte selon une course prédéterminée; un second élément de guidage, monté sur le premier élément de guidage, qui donne une force de tension prédéterminée à l'élément d'interconnexion de porte; un élément cylindrique, monté de part et d'autre du cadre de la porte, qui donne une force élastique au premier élément de guidage lors des positions d'élévation/abaissement du premier élément de guidage; un tablier articulé sur le premier élément de guidage, amené dans une position de déploiement et de repli lorsque le premier élément de guidage est en position d'élévation ou tiré sur le quai lorsque le premier élément de guidage est en position d'abaissement; et enfin, un élément de confinement, monté sur le parcours du premier élément de guidage et du second élément de guidage, qui interfère avec le mouvement ascendant du tablier lorsque la porte est fermée, et qui entraîne le tablier dans une position de repli. Le tablier de sécurité pour train peut prévenir les accidents causés par le vide entre le train et le quai, plus exactement entre la marchepied du train et le bord supérieur du quai, lors de la montée ou de la descente du train. De plus, l'exploitation du tablier de sécurité peut être adaptée à l'ouverture/fermeture de la porte du train, et son fonctionnement ne requiert pas l'installation d'une nouvelle alimentation ou d'un dispositif de commande supplémentaire.
