Abstract

Device intended to provide sealing of closure of a vehicle covered with a tarpaulin equipped with hoops, which can move along the vehicle, for supporting the tarpaulin. According to the invention, the closing hoop is composed of two hoops joined together, a standard hoop 8 for supporting the tarpaulin 6, and an additional hoop 11 of smaller cross-section placed so as to be directed towards the closing joint 9 fitted in the vertical end wall 2.

Description

Dispositif destiné à assurer l'étanchéité d'un véhicule bâché
La présente invention se rapporte à l'amélioration de l'étanchéité d'un véhicule totalement ou partiellement bâché, du type comportant une bâche soutenue par des arceaux, ou analogue, dont au moins l'un d'entre eux est mobile le long du véhicule.
Device for sealing a tarpaulin vehicle
The present invention relates to improving the sealing of a fully or partially covered vehicle, of the type comprising a tarpaulin supported by arches, or the like, at least one of which is movable along the vehicle.

D'une manière générale, un véhicule bâché, wagon ou camion par exemple, est constitué, comme représenté schématiquement sur la figure 1 jointe, d'un châssis 1, de deux parois verticales d'extrémité 2, et est équipé de deux chemins de roulement 3 disposés de part et d'autre du ch s- sis 1, sur toute la longueur de celui-ci. Sur ces chemins de roulement peuvent circuler des chariots 4 sur lesquels sont fixés les arceaux 5 qui supportent la bâche 6. A chaque extrémité, les chariots 7 sont des chariots doubles portant deux arceaux 8 généralement reliés entre eux, ceci de façon à faciliter les manoeuvres d'ouverture et de fermeture de la bâche. Generally, a tarpaulin vehicle, wagon or truck for example, consists, as shown diagrammatically in the attached FIG. 1, of a chassis 1, of two vertical end walls 2, and is equipped with two bearing 3 arranged on either side of the chassis 1, over the entire length thereof. On these raceways can circulate carriages 4 on which are fixed the poles 5 which support the tarpaulin 6. At each end, the carriages 7 are double carriages carrying two poles 8 generally connected together, this so as to facilitate maneuvers opening and closing of the cover.

Comme on le voit sur la figure 2, qui est une coupe selon la direction aa de la figure 1, l'étanchéité entre les arceaux 8 extrêmes et
les parois verticales d'extrémité 2 est assurée au moyen d'un joint 9, faisant face audit arceau d'extrémité sur toute la longueur de celui-ci, et noyé en général dans l'épaisseur de cette paroi extreme. Des moyens annexes de fermeture 10 à action manuelle permettent de maintenir les arceaux entre mes en contact étroit avec les joints 9 correspondants.
As can be seen in FIG. 2, which is a section along the direction aa of FIG. 1, the seal between the extreme hoops 8 and
the vertical end walls 2 is ensured by means of a seal 9, facing said end hoop over the entire length thereof, and generally embedded in the thickness of this extreme wall. Additional closing means 10 with manual action make it possible to maintain the arches between my in close contact with the corresponding seals 9.

En raison du poids assez élevé de la bâche à supporter et des diverses contraintes mécaniques à rencontrer, les arceaux sont largement dimensionnés et ont en général une section circulaire, comme on le voit sur la figure 2. La pression de contact entre le joint 9 et l'arceau extrême 8 est directement fonction de l'effort appliqué aux moyens de fermeture 10, et ledit effort est musculaire, donc limité. Due to the fairly high weight of the tarpaulin to be supported and the various mechanical constraints to be encountered, the arches are largely dimensioned and generally have a circular section, as can be seen in FIG. 2. The contact pressure between the gasket 9 and the extreme arch 8 is a direct function of the force applied to the closure means 10, and said force is muscular, therefore limited.

Par ailleurs, la bâche 6 n'est généralement pas parfaitement tendue sur les arceaux extrêmes et peut présenter quelques petits plis perpendiculaires à l'arceau. Furthermore, the sheet 6 is generally not perfectly stretched over the end hoops and may have some small folds perpendicular to the hoop.

I1 en résulte que l'on obtient rarement une étanchéité parfaite entre la paroi verticale d'extrémité et la bâche, du fait que l'effort musculaire développé par l'opérateur n'est jamais suffisant pour écraser assez 'les plis de la bâche, étant donné les surfaces assez importantes en contact. As a result, a perfect seal is rarely obtained between the vertical end wall and the cover, because the muscular effort developed by the operator is never sufficient to crush the folds of the cover enough, given the fairly large surfaces in contact.

Le véhicule bâché conforme à l'invention présente une étanchéité de fermeture améliorée par rapport à ces véhicules connus. Il est comme eux du type comportant une bâche soutenue par des arceaux dont au moins l'un d'entre eux est mobile le long du véhicule et vient se plaquer, en position de fermeture de la bâche, contre un joint correspondant pris dans une structure correspondante placée sur ledit véhicule en regard dudit arceau, mais il est caractérisé en ce que ledit arceau a une section profilée qui forme une arête du c8té dirigé vers ledit joint. The tarpaulin vehicle according to the invention has an improved closure seal compared to these known vehicles. It is like them of the type comprising a tarpaulin supported by arches of which at least one of them is movable along the vehicle and comes to be pressed, in the closed position of the tarpaulin, against a corresponding joint taken in a structure corresponding placed on said vehicle opposite said hoop, but it is characterized in that said hoop has a profiled section which forms an edge of the side directed towards said joint.

Suivant une forme particulièrement avantageuse de l'invention, ledit arceau est constitué par l'assemblage d'un premier arceau standard de support de bâche, par exemple à section circulaire, et d'un deuxième arceau de même longueur, mais de section plus faible, préférentiellement circulaire, ledit deuxième arceau étant accouplé au premier de façon à être en regard dudit joint. According to a particularly advantageous form of the invention, said arch is constituted by the assembly of a first standard arch of tarpaulin support, for example with circular section, and a second arch of the same length, but of smaller section , preferably circular, said second hoop being coupled to the first so as to be opposite said seal.

L'invention sera mieux comprise à l'aide de la description suivante de quelques exemples de réalisation, en référence aux dessins annexés dans lesquels - la figure 1 est une vue latérale schématique d'un wagon bâché classique, - la figure 2 montre, en coupe selon la direction aa de la figure 1, un dispositif d'étanchéité de fermeture de bâche de l'art antérieur, - la figure 3 montre, également en coupe selon la direction aa de la figure 1, une première forme de dispositif d'étanchéité de fermeture de bâche conforme à l'invention, - la figure 4 montre de la même façon une deuxième forme de dispositif d'étanchéité de fermeture de bâche conforme à l'invention, - la figure 5 montre de même une troisième forme de dispositif d'étanchéité de fermeture de bâche conforme à l'invention. The invention will be better understood with the aid of the following description of a few exemplary embodiments, with reference to the appended drawings in which - FIG. 1 is a schematic side view of a conventional tarpaulin wagon, - FIG. 2 shows, in section along the direction aa of FIG. 1, a tarpaulin closure sealing device of the prior art, FIG. 3 shows, also in section along the direction aa of FIG. 1, a first form of device for tarpaulin closure sealing according to the invention, - Figure 4 shows in the same way a second form of tarpaulin closure sealing device according to the invention, - Figure 5 similarly shows a third form of device cover closure seal according to the invention.

Les figures 1 et 2 ont déjà été explicitées ci-dessus. Elles permettent de se rendre compte du fait que ce genre de dispositif connu ne permet pas un écrasement suffisant des plis éventuels de la bâche 6 pour obtenir une étanchéité toujours satisfaisante. Le dispositif de l'invention a pour but de réduire la surface de bâche en contact avec le joint 9 de telle sorte que l'effort musculaire de l'opérateur permette un écrasement suffisant des plis éventuels de la bâche 9 autour du dernier arceau 8. Figures 1 and 2 have already been explained above. They make it possible to realize that this kind of known device does not allow sufficient crushing of the possible folds of the sheet 6 to obtain an always satisfactory seal. The aim of the device of the invention is to reduce the covering surface in contact with the seal 9 so that the muscular effort of the operator allows sufficient crushing of any folds of the covering 9 around the last arch 8.

Un premier mode de réalisation de l'invention, particulièrement avantageux pour sa simplicité de réalisation, est représenté sur la figure 3. A first embodiment of the invention, particularly advantageous for its simplicity of embodiment, is shown in FIG. 3.

Comme on le voit sur le dessin, on donne à l'arceau extrême, destiné à s'appliquer en position de fermeture contre le joint 9, une section profilée formant une arête du côté dirigé vers le joint 9, par l'adjonction à l'arceau standard 8, c1 section circulaire, d'un deuxième arceau 11 de même longueur, de section circulaire mais plus faible, et soudé comme représenté tout le long du premier de façon à être dirigé face au joint 9. L'ensemble ainsi constitué (8, 11), une fois recouvert par la hache 6, présente donc une arête permettant de s'enfoncer dans le joint élastique 9 plus profondement que précédemment, tel que sur la figure 2 par exemple. La déformation du joint 9 étant plus importante, les plis éventuels de la bâche 6 sont mieux écrasés que précédemment. As can be seen in the drawing, there is given to the end hoop, intended to be applied in the closed position against the seal 9, a profiled section forming an edge on the side directed towards the seal 9, by the addition to the standard hoop 8, c1 circular section, of a second hoop 11 of the same length, of circular section but smaller, and welded as shown all along the first so as to be directed opposite the joint 9. The assembly thus formed (8, 11), once covered by the ax 6, therefore has an edge making it possible to sink into the elastic seal 9 more deeply than previously, as in FIG. 2 for example. The deformation of the seal 9 being greater, the possible folds of the sheet 6 are better crushed than previously.

La figure 4 reprdsente une autre forme de réalisation de l'inven pion, dans laquelle l'arête de l'arceau de fermeture 8 est obtenue en donnant ao profil de cet arceau une section dissymétrique présentant une pointe en direction du joint 9. FIG. 4 represents another embodiment of the invention, in which the edge of the closing hoop 8 is obtained by giving a profile of this hoop an asymmetrical section having a point in the direction of the joint 9.

La figure 5 représente une autre forme de réalisation de l'invention, selon laquelle on utilise, pour l'arceau extrême de fermeture 8, un profil anguleux, carré dans l'exemple représenté, dont un angle pointe en direction du joint 9.  FIG. 5 represents another embodiment of the invention, according to which an angular profile, square in the example shown, whose angle points in the direction of the joint 9, is used for the end closure arch 8.
