Description

La présente invention concerne un système de plancher amovible pour un véhicule.The present invention relates to a removable floor system for a vehicle.

L'invention concerne également un véhicule, notamment un véhicule ferroviaire, comprenant un tel système de plancher amovible.The invention also relates to a vehicle, in particular a railway vehicle, comprising such a removable floor system.

L'invention concerne le domaine de la sécurisation des espaces de travail lors du montage ou de la maintenance de véhicules.The invention relates to the field of securing work spaces during the assembly or maintenance of vehicles.

Le document DE 197 44 124 A1 décrit un système de plancher amovible pour un véhicule comprenant une caisse, notamment un véhicule ferroviaire, le système de plancher comprenant au moins un élément de plancher, un dispositif de suspension apte à suspendre l'élément de plancher à la caisse, et définissant un axe de rotation de l'élément de plancher, et au moins un dispositif de verrouillage configuré pour être fixé à l'élément de plancher.The document DE 197 44 124 A1 describes a removable floor system for a vehicle comprising a body, in particular a railway vehicle, the floor system comprising at least one floor element, a suspension device capable of suspending the floor element from the body, and defining an axis rotation of the floor element, and at least one locking device configured to be fixed to the floor element.

Lors du montage ou de la maintenance d'un véhicule, il existe des positions en hauteur qui sont difficiles à atteindre par un agent, par exemple pour fixer ou remplacer des éléments fonctionnels ou décoratifs dans le véhicule.When assembling or maintaining a vehicle, there are height positions that are difficult to reach by an agent, for example to fix or replace functional or decorative elements in the vehicle.

Cette problématique est particulièrement importante dans des véhicules ayant une grande hauteur, tels que des véhicules ferroviaires à deux niveaux, des bus à deux niveaux ou encore des véhicules navals tels que des ferries ou des bateaux de croisière.This problem is particularly important in vehicles with a great height, such as double-deck railway vehicles, double-deck buses or even naval vehicles such as ferries or cruise ships.

Pour atteindre ces positions, on connaît l'utilisation d'échafaudages mobiles ou échelles mobiles qui sont positionnés par l'agent à l'emplacement désiré. Cependant, cette solution n'est pas entièrement satisfaisante en termes de sécurité de travail de l'agent, car l'échafaudage ou l'échelle n'est pas toujours stable.To reach these positions, the use of mobile scaffolding or mobile ladders which are positioned by the agent at the desired location is known. However, this solution is not entirely satisfactory in terms of the agent's working safety, because the scaffolding or ladder is not always stable.

En particulier lorsqu'un échafaudage mobile est placé sur un escalier à l'intérieur du véhicule, pour atteindre des positions en hauteur sur l'escalier, il est difficile de le positionner de manière à exclure un mouvement involontaire de celui-ci.In particular when a mobile scaffolding is placed on a staircase inside the vehicle, to reach high positions on the staircase, it is difficult to position it in such a way as to exclude involuntary movement thereof.

Par ailleurs, lors du montage de véhicules à deux niveaux superposés, avant l'agencement des escaliers, il existe des ouvertures entre les deux niveaux, qui présentent un risque de chute pour un agent depuis le niveau supérieur.Furthermore, when assembling vehicles with two superimposed levels, before the arrangement of the stairs, there are openings between the two levels, which present a risk of falling for an agent from the upper level.

De plus, la solution « échafaudage » est longue à mettre à mettre en place et engendre un risque de dégradation du véhicule.In addition, the “scaffolding” solution takes a long time to put in place and creates a risk of damage to the vehicle.

Un but de l'invention est de remédier à ces problèmes. En particulier, un but de la présente invention est d'obtenir un système facile à mettre en place dans un véhicule, qui permet au moins de réduire le risque de chutes d'un agent lors du montage ou de la maintenance du véhicule.An aim of the invention is to remedy these problems. In particular, an aim of the present invention is to obtain a system that is easy to implement in a vehicle, which at least makes it possible to reduce the risk of an agent falling during assembly or maintenance of the vehicle.

A cet effet, la présente invention a pour un objet un système de plancher amovible pour un véhicule comprenant une caisse, notamment un véhicule ferroviaire, le système de plancher comprenant au moins un élément de plancher, un dispositif de suspension apte à suspendre l'élément de plancher à la caisse, et définissant un axe de rotation de l'élément de plancher, et au moins un dispositif de verrouillage configuré pour être fixé à l'élément de plancher,For this purpose, the present invention relates to a removable floor system for a vehicle comprising a body, in particular a railway vehicle, the floor system comprising at least one floor element, a suspension device capable of suspending the element floor to the body, and defining an axis of rotation of the floor element, and at least one locking device configured to be fixed to the floor element,

l'élément de plancher, lorsqu'il est suspendu par le dispositif de suspension, étant mobile en rotation autour de l'axe de rotation entre une pluralité de positions de montage, et une position d'utilisation, dans laquelle l'élément de plancher est suspendu en outre par le dispositif de verrouillage, configuré pour verrouiller la position de l'élément de plancher par rapport à la caisse.the floor element, when suspended by the suspension device, being movable in rotation about the axis of rotation between a plurality of mounting positions, and a position of use, in which the floor element is further suspended by the locking device, configured to lock the position of the floor element relative to the body.

Grâce au système de plancher selon l'invention, il est alors possible de réduire le risque de chutes d'un agent lors du montage ou de la maintenance du véhicule, car l'agent est positionné sur l'élément de plancher dans la position d'utilisation. Ainsi, il n'est plus nécessaire de prévoir des échafaudages mobiles ou des échelles mobiles pour effectuer des travaux en hauteur.Thanks to the floor system according to the invention, it is then possible to reduce the risk of an agent falling during assembly or maintenance of the vehicle, because the agent is positioned on the floor element in the position of 'use. Thus, it is no longer necessary to provide mobile scaffolding or mobile ladders to carry out work at height.

Aussi, lorsque le système de plancher couvre une ouverture dans un plancher intermédiaire entre deux niveaux du véhicule, le risque d'une chute de l'agent à travers cette ouverture est réduit.Also, when the floor system covers an opening in an intermediate floor between two levels of the vehicle, the risk of the agent falling through this opening is reduced.

Par exemple, la base 32 est configurée pour être fixée à la poutre 6 par des vis 38 et/ou des rivets, non représentés, ou tout autre système permettant le blocage/verrouillage de la position du support.For example, the base 32 is configured to be fixed to the beam 6 by screws 38 and/or rivets, not shown, or any other system allowing the blocking/locking of the position of the support.

De préférence, la base 32 est réalisée en une seule pièce.Preferably, the base 32 is made in one piece.

En référence à la figure 4, le dispositif de verrouillage 14 comprend une tige de verrouillage 40 et un élément d'accueil 42 pour recevoir la tige de verrouillage 40.In reference to the figure 4 , the locking device 14 comprises a locking rod 40 and a receiving element 42 for receiving the locking rod 40.

La tige de verrouillage 40 est mobile en translation entre une position rétractée, visible par exemple sur la figure 1, prévue pour les positions de montage de l'élément de plancher 10 et une position de verrouillage, visible par exemple dans les figures 2 et 4, prévue pour la position d'utilisation de l'élément de plancher 10.The locking rod 40 is movable in translation between a retracted position, visible for example on the figure 1 , provided for the mounting positions of the floor element 10 and a locking position, visible for example in the figure 2 And 4 , intended for the position of use of the floor element 10.

La tige de verrouillage 40 est configurée pour être engagée, dans la position de verrouillage, dans la structure de plancher intermédiaire 8 de la caisse 2. Cela est par exemple illustré sur la figure 2.The locking rod 40 is configured to be engaged, in the locking position, in the intermediate floor structure 8 of the body 2. This is for example illustrated in the figure 2 .

En variante non représentée, la tige de verrouillage 40 est configurée pour être engagée dans une autre partie de la caisse 2, par exemple dans la poutre 6.As a variant not shown, the locking rod 40 is configured to be engaged in another part of the body 2, for example in the beam 6.

L'élément d'accueil 42 est configuré pour être fixé sur la surface de plafond 20 à la deuxième extrémité 24, par exemple par soudage, rivetage ou collage, et pour recevoir la tige de verrouillage 40.The docking element 42 is configured to be fixed to the ceiling surface 20 at the second end 24, for example by welding, riveting or gluing, and to receive the locking rod 40.

Un exemple d'un montage du système de plancher amovible 4 est maintenant décrit.An example of an assembly of the removable floor system 4 is now described.

Lors d'une étape optionnelle préliminaire, un agent fixe la première partie 26 du dispositif de suspension 12 et le dispositif de verrouillage 14 à l'élément de plancher 10.During a preliminary optional step, an agent fixes the first part 26 of the suspension device 12 and the locking device 14 to the floor element 10.

L'agent fixe ensuite la deuxième partie 28 du dispositif de suspension 12 à la poutre 6, par exemple au moyen des vis 38.The agent then fixes the second part 28 of the suspension device 12 to the beam 6, for example by means of screws 38.

Au présent stade du montage du système de plancher amovible 4, l'élément de plancher 10 est dans un état dégagé, dans lequel la première partie 26 est écartée de la deuxième partie 28.At the present stage of assembly of the removable floor system 4, the floor element 10 is in a disengaged state, in which the first part 26 is spaced from the second part 28.

L'agent engage ensuite le crochet avec le pivot 30 pour passer l'élément de plancher 10 de l'état dégagé vers un état de suspension, dans lequel la première partie 26 repose sur la deuxième partie 28. Par exemple, l'agent oriente l'élément de plancher 10 dans l'une des positions de montage, de préférence dans une position dans laquelle les surfaces 18, 20 de l'élément de plancher 10 s'étendent parallèlement à la direction d'élévation du véhicule, et déplace l'élément de plancher 10 vers le bas pour engager le crochet avec le pivot 30.The agent then engages the hook with the pivot 30 to move the floor element 10 from the disengaged state to a suspended state, in which the first part 26 rests on the second part 28. For example, the agent directs the floor element 10 in one of the mounting positions, preferably in a position in which the surfaces 18, 20 of the floor element 10 extend parallel to the direction of elevation of the vehicle, and moves the floor element 10 downwards to engage the hook with the pivot 30.

L'élément de plancher 10 est alors dans l'état de suspension, car il est suspendu par le dispositif de suspension 12.The floor element 10 is then in the suspended state, because it is suspended by the suspension device 12.

L'agent bascule ensuite l'élément de plancher 10 autour de l'axe de rotation R pour passer l'élément de plancher 10 des positions de montage, dont une est visible sur la figure 1, vers la position d'utilisation, visible sur la figure 2.The agent then tilts the floor element 10 around the axis of rotation R to move the floor element 10 from the mounting positions, one of which is visible on the figure 1 , towards the position of use, visible on the figure 2 .

L'agent verrouille ensuite l'élément de plancher 10 avec la caisse 2 en passant la tige de verrouillage 40 de la position rétractée à la position de verrouillage.The agent then locks the floor element 10 with the body 2 by moving the locking rod 40 from the retracted position to the locking position.

Un démontage du système de plancher amovible 4, par exemple après que le montage du véhicule ou la maintenance est terminé, se fait dans l'ordre inversé des étapes précitées.Dismantling of the removable floor system 4, for example after assembly of the vehicle or maintenance is completed, is done in the reverse order of the aforementioned steps.

On conçoit que le système de plancher 4 présente un grand nombre d'avantages.We can see that the floor system 4 has a large number of advantages.

En effet, le système 4 permet de réduire le risque de chutes de l'agent lors du montage ou de la maintenance du véhicule en rendant inutile l'utilisation d'un échafaudage mobile ou d'une échelle mobile.In fact, system 4 makes it possible to reduce the risk of the agent falling during assembly or maintenance of the vehicle by making the use of a mobile scaffolding or a mobile ladder unnecessary.

De plus, la mise en place du système de plancher 4 est très simple, et peut être effectuée par exemple par une seule personne en toute sécurité.In addition, the installation of the floor system 4 is very simple, and can be carried out for example by a single person in complete safety.

Le système de plancher 4 permet également la mise en sécurité du ou des agent(s) de la mise en place du système 4 jusqu'à la dépose de celui-ci. Toute la manoeuvre se fait en particulier depuis le premier niveau, et le risque de chute, par un trou tel que la trémie depuis le deuxième niveau, de l'agent mettant en place de système de plancher 4 est ainsi au moins réduit ou éliminé.The floor system 4 also allows the safety of the agent(s) from the installation of the system 4 until its removal. The entire maneuver is carried out in particular from the first level, and the risk of falling, through a hole such as the hopper from the second level, of the agent installing the floor system 4 is thus at least reduced or eliminated.

Aussi, le système de plancher 4 permet d'effectuer des travaux, tels que la maintenance ou le montage du véhicule, en simultanée sur le premier et le deuxième niveau, sans risque de chute ou de gênes.Also, the floor system 4 allows work, such as maintenance or vehicle assembly, to be carried out simultaneously on the first and second levels, without risk of falling or discomfort.

Bien entendu, d'autres modes de réalisation sont envisageables.Of course, other embodiments are possible.
