Abstract

The invention relates to an improved articulated door, especially for rail vehicles. Said articulated door 1 is equipped with an additional retaining device taking the form of an electromagnet 6 which, when this door is closed, keeps a pivoting footboard 2 in its position laid against the bottom of the carriage. The invention is used particularly for the equipment of rail vehicles.

Description

La présente invention se rapporte à une porte articulée, destinée en particulier à des véhicules ferroviaires et comportant un marchepied pivotant qui, recouvrant à l'état fermé l'alcôve d'accès est articulé sur ladite porte et accompagne les mouvements de cette dernière pe tels marchepieds reposent par leur propre poids sur le fond du wagon et sont affectés de l'inconvénient de pouvoir être soulevés par un vent fort pendant le déplacement du véhicule, ce qui provoque des courants d'air, entre autres la pénétration de neige fondue dans le wagon.Conformément à la présente invention, ces inconvénients sont évités par le fait qu'il est prévu un dispositif supplémentaire individuel de retenue qui , lorsque la porte est fermée, maintient fermement le marchepied pivotant dans sa position appliquée contre le fond du wagon. Selon une autre caractéristique de l'nvention,, le dispositif de retenue est réalisé sous la forme deun électro-aimant qui, incorporé dans le fond du wagon, attire contre ce dernier liextrémité du marchepied pivotant. The present invention relates to an articulated door, intended in particular for railway vehicles and comprising a pivoting step which, covering in the closed state the access alcove is articulated on said door and accompanies the movements of the latter eg footboards rest by their own weight on the bottom of the wagon and are affected by the disadvantage of being able to be lifted by a strong wind during the movement of the vehicle, which causes drafts, inter alia the penetration of melted snow into the In accordance with the present invention, these drawbacks are avoided by the fact that an additional individual retaining device is provided which, when the door is closed, firmly maintains the pivoting step in its position applied against the bottom of the wagon. According to another characteristic of the invention, the retaining device is produced in the form of an electromagnet which, incorporated in the bottom of the wagon, attracts against the latter the end of the pivoting step.

Selon une autre caractéristique de ltinvention, ltélectro-aimant est raccordé à une source de courant dépendante de la vitesse, de sorte que cet électro-aimant n'agit qu'en présence d'une grande vitesse de déplacement. According to another characteristic of the invention, the electromagnet is connected to a speed-dependent current source, so that this electromagnet acts only in the presence of a high speed of movement.

L'invention va à présent être décrite plus en détail à titre d'exemple nullement limitatif en regard du dessin annexé sur lequel
la figure 1 est une vue en plan de la porte selon l'invention ; et
la figure 2 est une couipe selon la ligne II-II de la figure 1.
The invention will now be described in more detail by way of non-limiting example with regard to the appended drawing in which
Figure 1 is a plan view of the door according to the invention; and
Figure 2 is a section along the line II-II of Figure 1.

Comme le montre le dessin, une porte articulée 1 est incorporée dans un wagon et elle possède à son extré- mité inférieure un marchepied pivotant 2 articulé par des charnières, qui recouvre une alc8ve d'accès 7 et auquel, comme l-'indiquent des traits mixtes sur la figure 1, un bras télescopique 4 imprime un pivotement vers le haut lors de- l'ouverture de la porte 1. Le marchepied pivotant 2 comporte à son extrémité inférieure une garniture d'étanchement 5 en caout chouc, par laquelle il est appliqué sur la face inférie-ure en vue de garantir un contact irréprochable par pression de ladite garniture 5 avec le fond du wagon dans toutes les circonstances, par exemple lorsque de la crasse est présente ou que la pression du vent s, exerce dans la direction des flèches Facette extrémité du marchepied pivotant, un dispositif de retenue 3 en caoutchouc maintient rigidement en place un induit magnétique 8 excité par un électro-aimant 6 installé dans le fond du wagon Cet électro-aimant ó et raccordé à une source de courant dépendante de la vitesse et ne délivrant du courant électrique que lorsque la vitesse de déplacement est accrue, de sorte que le marchepied pivotant est fixé au sol seulement lorsque le véhicule se déplace à une telle vitesse. A la, place du dispositif de retenue 3 en caoutchouc, il est possible de prévoir un montage articulé, pour faire en sorte que la force magnétique agisse plus facilement sur l'induit dans chaque position, ainsi que pour permettre une compensation de tolérances de fabrication. As the drawing shows, a hinged door 1 is incorporated in a wagon and has at its lower end a pivoting step 2 hinged by hinges, which covers an access alc8ve 7 and to which, as shown in dashed lines in FIG. 1, a telescopic arm 4 gives an upward pivot when the door is opened. The pivoting step 2 has at its lower end a sealing gasket 5 made of rubber, by which it is applied to the underside-ure in order to guarantee impeccable contact by pressure of said lining 5 with the bottom of the wagon in all circumstances, for example when dirt is present or that the wind pressure is exerted in the direction of arrows Facet end of the pivoting step, a rubber retainer 3 rigidly holds in place a magnetic armature 8 excited by an electromagnet 6 installed in the bottom of the wagon This electromagnet ó and ra cconnected to a speed-dependent power source and supplying electric current only when the travel speed is increased, so that the swivel step is fixed to the ground only when the vehicle is traveling at such speed. Instead of the rubber retainer 3, it is possible to provide an articulated assembly, to make the magnetic force act more easily on the armature in each position, as well as to allow compensation for manufacturing tolerances. .

L'invention ne se limite pas à l'exemple de réalisation illustré parc-e que, au lieu d'être disposé au centre, l'électro-aimant peut aussi se trouver dans un coin, de préférence sur des charnières de la porte. The invention is not limited to the example of embodiment illustrated in that, instead of being placed in the center, the electromagnet can also be located in a corner, preferably on hinges of the door.

Il va donc de soi que de nombreuses modifications peuvent être apportées à la porte articulée décrite et repré sentée, sans sortir du cadre de l'inyentîon.  It therefore goes without saying that numerous modifications can be made to the hinged door described and shown, without going beyond the scope of the invention.
