selon l' invention.according to the invention.
La chaine 1 representee sur la figure 1 est formee de maillons 2 articules entre eux autour d'axes verticaux. Une premiere extremite 3 de la chane est fixee a un franc 4 d'un support en forme de canal. Une premiere branche 6 de la chaine, s'etendant en ligne droite a partir de ltextremite 3 le long du franc 4, se raccorde par une boucle 7 en forme d'arc convexe a une seconde branche 8 qui s'etend en ligne droite le long d'un second franc vertical non represente du canal, jusqu'a une seconde extremite 9. Les deux branches reposent sur un fond 10 du canal. Des moyens d'entranement non representes permettent de deplacer l'extremite 9 le long du franc correspondent selon la double fleche F1. Lorsque l'extremite 9 se deplace vers la droite, c'est-a-dire vers la boucle 7, la longueur de la branche 8 diminue et la longueur de la branche 6 augmente correlativement, et inversement The chain 1 represented in FIG. 1 is formed of links 2 articulated together around vertical axes. A first end 3 of the chain is fixed to a franc 4 of a channel-shaped support. A first branch 6 of the chain, extending in a straight line from the end 3 along the franc 4, is connected by a loop 7 in the form of a convex arc to a second branch 8 which extends in a straight line the along a second vertical franc not represented by the canal, up to a second end 9. The two branches rest on a bottom 10 of the canal. Drive means not shown make it possible to move the end 9 along the franc correspond according to the double arrow F1. When the end 9 moves to the right, that is to say towards the loop 7, the length of the branch 8 decreases and the length of the branch 6 increases correlatively, and vice versa
lorsque l'extremite 9 se deplace dans l'autre sees. when end 9 moves into the other sees.
La figure 2, sur laquelle le second franc du canal est indique par la reference 11, montre un phenomene qui se produit avec un dispositif de l'etat de la technique dans lequel le fond 10 du canal est fixe sur toute sa largeur. Lorsque l'extremite 9 de la chane se deplace en direction de la boucle 7 dans le sens de la fleche F2, le frottement de la branche 8 sur le fond 10 s 'oppose a son deplacement, de sorte qu'elle se deforme en formant une ondulation 12 qui s'eloigne du franc 11. Pour eviter ce phenomena, dans le dispositif selon l' invention represente sur la figure 3, le support 20 en forme de canal comporte un fond composite. Le canal 20 comprend deux profiles lateraux 21, 22, symetriques l'un de l'autre par rapport au plan vertical median P du support. Ces profiles presentent une section en L comprenant une aile verticale 23, 24 definissant un franc du canal, et une aile horizontale 25, 26 repliee Figure 2, on which the second franc of the channel is indicated by the reference 11, shows a phenomenon which occurs with a device of the state of the art in which the bottom 10 of the channel is fixed over its entire width. When the end 9 of the chain moves in the direction of the loop 7 in the direction of the arrow F2, the friction of the branch 8 on the bottom 10 is opposed to its displacement, so that it deforms forming a corrugation 12 which moves away from the franc 11. To avoid this phenomenon, in the device according to the invention represented in FIG. 3, the support 20 in the form of a channel comprises a composite bottom. The channel 20 comprises two lateral profiles 21, 22, symmetrical to one another with respect to the vertical median plane P of the support. These profiles have an L-shaped section comprising a vertical wing 23, 24 defining a channel franc, and a horizontal wing 25, 26 folded
horizontalement vers l'autre profile a partir du bord infe- horizontally towards the other profile from the lower edge
rieur de l'aile verticale. Un profile 27 est fixe sur la face interne de l'aile 23 definissant le premier franc du canal. Le profile 27 comprend une aile intermediaire plane et horizon tale 28 a partir des deux bords longitudinaux de laquelle s'etendent vers le teas des ailes verticales respectives 29, 30, l'aile 29 etant accolee au franc 23 et solidarisee a celui-ci par exemple par soudage. L'aile 30 porte une serie d'arbres horizontaux 31, situes a la meme hauteur et a egale distance les uns des autres le long du canal, sur lesquels des galets respectifs 32 vent montes de maniere a tourner libre meet. Les galets 32 s'etendent sur la quasi totalite de la distance laterale entre l'aile 30 et le franc 24, audessus de l'aile 26, et presentent une legere conicite, de telle sorte que leur generatrice superieure 33 est legerement inclinee vers le teas en direction du franc 24. Ainsi, tandis que la premiere branche 6 de la chane, dans laquelle vent loges des cables 35, repose sur une partie de fond plane fixe 28, comme dans letat de la technique, la seconde branche 8 repose sur les generatrices 33 des galets, situees au voisinage du plan de la partie fixe 28, de sorte que les galets vent entranes en rotation par le deplacement de la branche 8 et n'opposent pratiquement pas de resistance a ce deplacement. L'inclinaison des generatrices 33 tend a appliquer la branche 8 contre le franc 24, par gravite, contribuant a assurer la linearite de cette branche. Avantageusement, des patins 34 en materiau a faible-coefficient-de frottement vent prevus sur le franc 24, pour venir en contact avec la branche 8 et reduire encore la laughing of the vertical wing. A profile 27 is fixed on the internal face of the wing 23 defining the first franc of the channel. The profile 27 comprises a flat intermediate wing and horizontal horizon 28 from the two longitudinal edges from which extend towards the teas of the respective vertical wings 29, 30, the wing 29 being attached to the franc 23 and secured to it by example by welding. The wing 30 carries a series of horizontal shafts 31, situated at the same height and at equal distance from each other along the channel, on which respective rollers 32 are mounted so as to rotate freely to meet. The rollers 32 extend over almost the entire lateral distance between the wing 30 and the franc 24, above the wing 26, and have a slight conicity, so that their upper generator 33 is slightly inclined towards the teas in the direction of the franc 24. Thus, while the first branch 6 of the chain, in which the wind cells of the cables 35, rests on a fixed flat bottom part 28, as in the prior art, the second branch 8 rests on the generators 33 of the rollers, located in the vicinity of the plane of the fixed part 28, so that the rollers are driven in rotation by the movement of the branch 8 and practically do not oppose resistance to this displacement. The inclination of the generators 33 tends to apply the branch 8 against the franc 24, by gravity, helping to ensure the linearity of this branch. Advantageously, pads 34 made of a material with a low coefficient of wind friction provided on the franc 24, to come into contact with the branch 8 and further reduce the
resistance opposee au deplacement de celle-ci. resistance opposed to the displacement thereof.
Dans une variante de realisation, le canal 20 est constitue d'un profile en U dans lequel est rapporte un autre profile en U de dimensions plus petites et en position inversee. Les galets vent alors portes sur l'un des francs de ce dernier profile. Au lieu d'etre tronconiques comme dans l'exemple decrit, les galets peuvent etre cylindriques. Il est alors avantageux, pour maintenir l'inclinaison de leur generatrice superieure, In an alternative embodiment, the channel 20 consists of a U-shaped profile in which another U-shaped profile of smaller dimensions and in the inverted position is attached. The pebbles are then carried on one of the francs of this last profile. Instead of being frustoconical as in the example described, the rollers can be cylindrical. It is then advantageous, to maintain the inclination of their upper generator,
que les axes de rotation des galets soient eux-memes inclines. that the axes of rotation of the rollers are themselves inclined.
