Abstract
Description
La présente invention concerne un dispositif de bâchage pour véhicule articulé, tel que par exemple un wagon articulé à trois ou quatre essieux compose de deux demi-wagons accouplés par une liaison centrale. The present invention relates to a tarpaulin device for an articulated vehicle, such as for example an articulated wagon with three or four axles composed of two half-wagons coupled by a central link.
Les véhicules articulés bâchés sont généralement constitués d'au moins deux demi-véhicules reliés l'un à l'autre par une articulation et composés chacun d'un châssis équipé à ses deux extrémités de parois métalliques entre lesquelles peut être fixée une bâche supportée sur toute sa longueur par une succession d'arceaux roulant sur les rails prevus à cet effet. Entre les cloisons métalliques situées du côté de l'articulation des demi-véhicules est ménagé un espace suffisant pour permettre le débattement en courbe des deux demichâssis. The articulated tarpaulin vehicles generally consist of at least two half-vehicles connected to each other by a hinge and each composed of a chassis equipped at its two ends with metal walls between which a tarpaulin supported on its entire length by a succession of arches rolling on the rails provided for this purpose. Between the metal partitions located on the side of the articulation of the half-vehicles, sufficient space is provided to allow the deflection in curve of the two half-chassis.
Ces dispositifs connus présentent de nombreux inconvénients - les deux parois centrales, c'est-a-dire situees du côté de l'articu
lation, représentent pour l'essieu central, ou les essieux centraux,
un poids mort qui diminue considérablement la capacité de chargement
de l'ensemble du wagon - le prix de réalisation des cloisons centrales est élevé, ce qui
renchérit le coût du véhicule - les dispositifs de fermeture de bâche sont au nombre de quatre,
alors qu'il n'y en a que deux sur les wagons ordinaires non
articulés, ce qui augmente le prix global, les coûts d'entretien,
et les risques de fuites - pour le chargement, le wagon articulé est divisé, en raison de la
présence des cloisons centrales, en deux compartiments, ce qui
interdit le chargement de certaines charges longues et indivisibles;; - l'épaisseur des cloisons centrales ne peut être utilisée pour
le chargement, ce qui réduit d'autant le volume utile.These known devices have many disadvantages - the two central walls, that is to say located on the side of the articu
lation, represent for the central axle, or the central axles,
dead weight which considerably reduces the loading capacity
of the entire wagon - the cost of producing the central partitions is high, which
increases the cost of the vehicle - there are four tarpaulin closers,
when there are only two on ordinary wagons not
articulated, which increases the overall price, maintenance costs,
and the risk of leaks - for loading, the articulated wagon is divided, due to the
presence of the central partitions, in two compartments, which
prohibits the loading of certain long and indivisible loads; - the thickness of the central partitions cannot be used for
loading, which reduces the useful volume accordingly.
Le dispositif de bâchage de l'invention ne présente pas les inconvénients des dispositifs précédents, ne necessitant pas la présence de cloisons centrales fixes. Il est du type comportant une bâche coulissante par portion de véhicule, chacune des bâches des portions extrêmes étant fixée par sa partie extrême aux cloisons d'extrémité du véhicule, et est caractérise en ce que chaque extré- mité coulissante de chacune desdites bâches est montée sur un ensemble coulissant comportant un ou plusieurs arceaux de soutien fixé(s) sur deux chariots de roulement, un de chaque côté du vehicule, et en ce qu'au moins un parmi deux ensembles coulissants adjacents comporte un supplément de bâche extensible lui-même terminé par un arceau mobile de fermeture muni d'un dispositif de fixation étanche contre l'extré- mité correspondante de la bâche adjacente. The tarpaulin device of the invention does not have the disadvantages of the previous devices, not requiring the presence of fixed central partitions. It is of the type comprising a sliding cover per portion of vehicle, each of the covers of the end portions being fixed by its end portion to the end partitions of the vehicle, and is characterized in that each sliding end of each of said covers is mounted on a sliding assembly comprising one or more support arches fixed on two rolling carriages, one on each side of the vehicle, and in that at least one of two adjacent sliding assemblies has an additional extendable tarpaulin itself terminated by a movable closing hoop fitted with a tight fixing device against the corresponding end of the adjacent tarpaulin.

On reconnaît sur la figure 1 un wagon de marchandises articulé comportant, de maniere classique, trois essieux (1, 2, 3) et deux demi-châssis (4, 5) reposant sur un châssis central 6. Chaque demi. châssis (4, 5) est muni. d'une bâche (7, 8) coulissante dont la partie extrême est fixée aux parois d'extrémité (9, 10 ) de chaque demi-châssis, et dont l'autre extrémité vient se fermer sur les parois centrales (11, 12) du wagon. We recognize in Figure 1 an articulated goods wagon comprising, conventionally, three axles (1, 2, 3) and two half-chassis (4, 5) resting on a central chassis 6. Each half. chassis (4, 5) is provided. a sliding tarpaulin (7, 8), the end part of which is fixed to the end walls (9, 10) of each half-frame, and the other end of which closes on the central walls (11, 12) from the wagon.
Les figures 2 et 3 montrent schematiquement le même wagon muni du dispositif de bâchage de l'invention avec ses bâches (7, 8) respectivement ouvertes et fermees. On voit que le wagon, étant dépourvu de parois centrales, ne présente aucun des nombreux inconvénients inhérents à leur présence, et enuméres précédemment. Figures 2 and 3 show schematically the same wagon fitted with the covering device of the invention with its covers (7, 8) respectively open and closed. We see that the wagon, being devoid of central walls, has none of the many drawbacks inherent in their presence, and listed above.
On se reportera maintenant aux figures 4 à 7 qui montrent plus en détails le dispositif de l'invention. La partie extrême mobile de chaque bâche 7 et 8 est constituée par un ensemble 16 coulissant sur les rails de roulement lateraux 1.1 et comportant - deux chariots de roulement 12, un de chaque côté du wagon, munis
chacun de quatre galets de roulement 13, - deux arceaux (14, 15) fixés sur les chariots 12, à chacune de leurs
extrémités, - quatre glissières 17, deux de chaque côte du wagon, dans lesquelles
coulissent des bras 18 guidés par des galets 19 et munis chacun d'une
butée arrière de fin de course 20, - un arceau de fermeture, respectivement 21 pour la bâche 7 et 22 pour
la bâche 8, mobile longitudinalement et monté aux extrémités des
bras 18 opposés aux butees 20.We will now refer to Figures 4 to 7 which show in more detail the device of the invention. The movable end part of each sheet 7 and 8 is constituted by an assembly 16 sliding on the lateral running rails 1.1 and comprising - two rolling carriages 12, one on each side of the wagon, provided
each of four rollers 13, - two arches (14, 15) fixed on the carriages 12, at each of their
ends, - four slides 17, two on each side of the wagon, in which
slide arms 18 guided by rollers 19 and each provided with a
rear end-of-travel stop 20, - a closing hoop, respectively 21 for the cover 7 and 22 for
the sheet 8, movable longitudinally and mounted at the ends of the
arms 18 opposite the stops 20.
Les portions de bâche (23, 24) recouvrant les parties comprises entre les arceaux de fermeture (21, 22) et les arceaux d'extrémité 15 des chariots 12 sont des portions "en accordéon, donc extensibles. The cover portions (23, 24) covering the parts included between the closing arches (21, 22) and the end arches 15 of the carriages 12 are "accordion" portions, and therefore extendable.
On voit donc que, par le jeu des bras coulissants 18 et des portions variables 23 et 24, l'espace compris entre les deux arceaux d'extrémité 15 va pouvoir s'allonger et se retrécir librement de manière à permettre le passage en courbe du wagon articule.It can therefore be seen that, by the play of the sliding arms 18 and of the variable portions 23 and 24, the space between the two end arches 15 will be able to lengthen and shrink freely so as to allow the curve to pass through. articulated wagon.
De manière à bloquer les chariots 12 le long des rails dans leur position de fermeture des bâches, chaque chariot 12 est muni d'une encoche inférieure 25 dans laquelle vient s'enclencher un doigt de verrouillage automatique 26 en forme de L. Ces doigts de verrouillage 26 sont articulés sur les châssis (4, 5) autour d'axes de rotation 27, rappelés par des ressorts 28 et liés deux à deux de part et d'autre du wagon par une barre d'accouplement 29 (figure 5). In order to block the carriages 12 along the rails in their tarpaulin closing position, each carriage 12 is provided with a lower notch 25 in which an L-shaped automatic locking finger 26 engages. locking 26 are articulated on the chassis (4, 5) around axes of rotation 27, recalled by springs 28 and linked in pairs on either side of the wagon by a coupling bar 29 (Figure 5).
Comme on le voit en particulier sur l'agrandissement de la figure 7, les arceaux de fermeture 21 et 22 ont des profils s'emboitant l'un dans l'autre, l'étanchéité étant assurée à l'aide d'un joint 30, et les portions de bâche extensibles 23 et 24 étant fixées à l'aide de couvre-joints 24. De manière classique par ailleurs, les arceaux de fermeture 21 et 22 sont rendus solidaires à l'aide d'anneaux de verrouillage (31, 32) fixés aux extrémités des bras 18 comme figuré sur le dessin de la figure 4. As can be seen in particular on the enlargement of FIG. 7, the closing arches 21 and 22 have profiles which fit into one another, the seal being ensured by means of a seal 30 , and the extendable tarpaulin portions 23 and 24 being fixed using joint covers 24. In a conventional manner, moreover, the closing arches 21 and 22 are made integral with the aid of locking rings (31, 32) fixed to the ends of the arms 18 as shown in the drawing in FIG. 4.
Bien évidemment, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit, mais englobe tous les dispositifs équivalents. Par exemple, on pourra avantageusement utiliser pour la partie centrale, un dispositif tel que décrit dans la demande de brevet français déposée par la demanderesse le 22 Septembre 1978 sous le NO. 78 27256. Dans ce-cas, seul un parmi deux ensembles coulissants aura besoin d'être muni d'un ensemble mobile d'extrémité destiné à permettre le passage en courbe, tel qu'un des ensembles (17, 18, 19, 23) précédemment décrit. L'invention s'applique également aux véhicules articules à trois éléments ou plus. Obviously, the invention is not limited to the embodiment which has just been described, but encompasses all equivalent devices. For example, one could advantageously use for the central part, a device as described in the French patent application filed by the applicant on September 22, 1978 under the NO. 78 27256. In this case, only one of two sliding assemblies will need to be provided with a movable end assembly intended to allow passage in a curve, such as one of the assemblies (17, 18, 19, 23 ) previously described. The invention also applies to articulated vehicles with three or more elements.
L'invention trouve son utilisation dans l'industrie du transport de marchandises. The invention finds its use in the freight transport industry.
