DISPOSITIF DE GUIDAGE ET D'ANCRAGE DES CHARIOTS DE
SERVICE DANS LES AERONEFS La présente invention concerne un dispositif pour guider dans les aéronefs les chariots de service (communément appelés Troleys) et les ancrer au plancher en cas de dépression brutale de l'aéronef afin d'assurer la sécurité des passagers et du personnel navigant. GUIDANCE AND ANCHORING DEVICE FOR TROLLEYS
SERVICE IN AIRCRAFT The present invention relates to a device for guiding in service aircraft trolleys (commonly called Troleys) and anchoring them to the floor in the event of sudden depression of the aircraft in order to ensure the safety of passengers and flight personnel .

Traditionnellement, lesdits troleys comportent des roulettes qui leur permettent d'être poussés ou tirés par le personnel de service dans l'allée centrale de l'aéronef. Ils sont donc totalement libres et leur conduite est délicate du fait de l'exiguïté de l'espace central. D'autre part, en cas de dépression brutale de l'aéronef ils constituent un danger certain pour les passagers et le personnel au même titre que tout objet non fixé ou non enfermé dans les racks (coffres à bagages) Le dispositif selon l'invention permet de remédier à ces inconvénients. Traditionally, said troleys have rollers which allow them to be pushed or pulled by service personnel in the central aisle of the aircraft. They are therefore completely free and their conduct is delicate due to the small size of the central space. On the other hand, in the event of a sudden depression of the aircraft, they constitute a certain danger for passengers and staff just like any object that is not fixed or not enclosed in the racks (luggage compartments). The device according to the invention overcomes these disadvantages.

Il peut comporter en effet selon une première caractéristique un rail-guide fixé sur le plancher dans l'axe de la cellule entre les sièges. Ce rail peut être pourvu de deux ailes permettant l'ancrage des troleys en cas de dépression brutale de l'aréonef. On peut associer à ce rail un dispositif rétractable d'occlusion de l'espace constitué par l'âme creuse du rail, ceci afin d'éviter l'encrassement dudit espace, ainsi que les inconvénients qui pourraient résulter de sa présence pour la sécurité des personnes (talons de chaussures de femme, par exemple). According to a first characteristic, it may in fact comprise a guide rail fixed to the floor in the axis of the cell between the seats. This rail can be provided with two wings allowing the anchoring of the troleys in the event of sudden depression of the aircraft. We can associate with this rail a retractable device for occluding the space formed by the hollow core of the rail, this in order to avoid fouling of said space, as well as the drawbacks which could result from its presence for the safety of people (women's shoe heels, for example).

Les troleys peuvent eux être équipés d'un dispositif rétractable ou relevable (appelé ci-après crosse) d'une forme adaptée au profil du rail et qui, lors de la mise en service du dispositif par le personnel utilisateur vient s'enclencher dans le rail facilitant ainsi le guidage des troleys. The troleys can themselves be fitted with a retractable or liftable device (hereinafter called a stock) of a shape adapted to the profile of the rail and which, when the device is put into service by the user personnel, engages in the rail thus facilitating the guiding of the troleys.

Selon des modes particuliers de réalisation : - Le profil du rail comporte deux ailes permettant le passage du dispositif de guidage et d'ancrage fixé sur le troley - Le rail peut comporter un dispositif d'occlusion rétractable, mû par le dispositif de guidage, au passage du troley. Ce dispositif peut par exemple être constitué de plaques de dimensions et de matière constitutive adaptées, recevant un système de ressorts permettant leur déplacement transversal lors du passage du troley et leur remise en position sitôt après. According to particular embodiments: - The profile of the rail comprises two wings allowing the passage of the guiding and anchoring device fixed on the troley - The rail can comprise a retractable occlusion device, moved by the guiding device, at passage of the troley. This device can for example be made up of plates of suitable dimensions and constituent material, receiving a system of springs allowing their transverse displacement during the passage of the troley and their repositioning immediately after.

Sous le troley, un ou plusieurs dispositifs de guidage et d'ancrage (crosse) peuvent être fixés. Leurs formes et dimensions sont adaptées à celles de l'âme du rail. Il peuvent comporter un dispositif de relevage et de blocage afin de les maintenir en position verticale (en service) ou en position horizontale (hors service). Under the troley, one or more guiding and anchoring devices (stock) can be fixed. Their shapes and dimensions are adapted to those of the rail core. They may include a lifting and blocking device in order to keep them in a vertical position (in service) or in a horizontal position (out of service).

En tête de dispositif, le rail peut être évasé en forme de tulipe pour permettre l'introduction facile des crosses dans le rail.  At the head of the device, the rail can be flared in the shape of a tulip to allow the easy introduction of the hooks into the rail.

Les dessins annexés illustrent l'invention. The accompanying drawings illustrate the invention.

La figure1 représente vu en coupe l'ensemble du dispositif dans sa position de fonctionnement. Figure 1 shows a sectional view of the entire device in its operating position.

La figure 2 représente vu de dessus le dispositif d'occlusion du rail dans sa position ouverte, c'est à dire en fonctionnement. Figure 2 shows a top view of the rail occlusion device in its open position, that is to say in operation.

La figure 3 représente vu en coupe l'ensemble du dispositif dans sa position de repos. Figure 3 shows a sectional view of the entire device in its rest position.

La figure 4 représente vu de dessus le dispositif d'occlusion dans sa position fermée, c'est à dire au repos. Figure 4 shows a top view of the occlusion device in its closed position, that is to say at rest.

La figure 5 représente vue de profil la partie du dispositif fixée sur le troley. Figure 5 shows a side view of the part of the device fixed to the troley.

La figure 6 représente vue de face la partie du dispositif fixée sur le troley La figure 7 représente vue de dessous la partie du dispositif fixée sur le troley En référence à ces dessins, le dispositif comporte un rail (2) comportant deux ailes qui peuvent être asymétriques ainsi qu'un dispositif d'occlusion, rétractable, constitué par exemple de plaques (3) qui s'effacent lors du passage de la crosse du dispositif de guidage (1) et reprennent leurs emplacements d'origine dès le passage accompli de ce dernier, ce mouvement pouvant être assuré par exemple par des ressorts de rappel (4). FIG. 6 represents a front view of the part of the device fixed on the troley FIG. 7 represents a bottom view of the part of the device fixed on the troley With reference to these drawings, the device comprises a rail (2) comprising two wings which can be asymmetrical as well as a retractable occlusion device, consisting for example of plates (3) which disappear when the stock of the guide device (1) passes and return to their original locations as soon as this last, this movement can be ensured for example by return springs (4).

Dans la forme de réalisation selon les figures 5,6, 7, les dispositifs de guidage et d'ancrage (1) comportent un dispositif de relevage (5) et un dispositif de blocage (6) dans les deux positions possibles, en service ou hors service. In the embodiment according to FIGS. 5, 6, 7, the guiding and anchoring devices (1) comprise a lifting device (5) and a locking device (6) in the two possible positions, in service or out of order.

Selon une variante non illustrée, le rail peut être encastré dans le plancher de l'aéronef permettant d'éviter tout relief, et conserver une planéité générale de la surface du plancherAccording to a variant not illustrated, the rail can be embedded in the floor of the aircraft making it possible to avoid any relief, and to maintain a general flatness of the surface of the floor.
