Title
(EN) PNEUMATIC DOOR OPERATOR HAVING NOVEL PNEUMATIC ACTUATOR AND LOCK
(FR) FERME-PORTE PNEUMATIQUE AVEC NOUVEL ACTUATEUR PNEUMATIQUE ET NOUVEAU DISPOSITIF DE BLOCAGE
Abstract
(EN)
A power door operator for transit vehicles utilizing a rodless pneumatic cylinder (10) to open and close doors (2, 3) in the sidewall of a vehicle. Door movement having a controlled door edge force is achieved through coupling an external piston (11) of the cylinder and vehicle doors through belt (16). Magnetic coupling between internal and external pistons of the cylinder provide force having breakaway value applied to the operated door. A novel lock (30, 31, 32, 33) operated by admission of air to the cylinder (10) latches or unlatches the door in its closed position subsequent or prior to door closing or opening. Control of door motion at the ends of its travel is achieved through the use of a novel differential area (10a) in the cylinder. Piston force is modified for positions approaching either end of the cylinder using a sliding rod (40) contained by the piston (10a). Movement of the rod modifies available force.
(FR)
Le ferme-porte pneumatique décrit, qui est conçu pour des véhicules de transport publique utilise un cylindre pneumatique sans tige (10) assurant l'ouverture et la fermeture des portes (2, 3) de la paroi latérale d'un véhicule. Les mouvements des portes accompagnés d'une régulation de la force de pression des bords de porte sont exécutés par l'intermédiaire d'un couplage par courroie (16) entre un piston externe (11) du cylindre et les portes du véhicule. Un couplage magnétique entre les pistons interne et externe du cylindre assure l'application d'une force ayant une valeur de décollage sur la porte actionnée. Un nouveau dispositif de blocage (30, 31, 32, 33) actionné par admission d'air dans le cylindre (10) assure le verrouillage ou le déverrouillage de la porte se trouvant en position fermée après ou avant la fermeture ou l'ouverture de la porte. La commande des mouvements de la porte à la fin de sa course s'effectue grâce à l'utilisation d'une nouvelle zone différentielle (10a) située dans le cylindre. La force du piston est modifiée pour les positions voisines de l'une ou l'autre extrémité du cylindre au moyen d'une tige coulissante (40) contenue dans le piston (10a). Le mouvement de la tige modifie la force disponible.
