Description

L'invention concerne un distributeur pour bande de papier en rouleau sans mandrin selon le préambule de la revendication 1 (US-A-3 329 366).The invention relates to a dispenser for paper tape made of roller without core according to the preamble of claim 1 (US-A-3,329,366).

L'invention concerne plus particulièrement un distributeur de papier, destiné notamment aux collectivités, dans lequel le distributeur, en forme de boítier, comporte au moins un rouleau monté sur une tige support. L'extrémité libre de la bande de papier en rouleau est destinée à dépasser au travers d'un orifice de distribution, réalisé par exemple sous la forme d'une fente ou d'une fenêtre, et l'utilisateur, en tirant sur l'extrémité libre, provoque le dévidage du rouleau par rotation autour de l'axe fixe de la tige support.The invention relates more particularly to a dispenser of paper, intended in particular for communities, in which the distributor, in form of housing, comprises at least one roller mounted on a rod support. The free end of the roll paper strip is intended for protrude through a dispensing orifice, made for example under the shape of a slot or window, and the user, pulling on the end free, causes the unwinding of the roll by rotation around the fixed axis of the support rod.

L'invention se rapporte plus particulièrement aux distributeurs de papier destinés à recevoir des rouleaux sans mandrin, c'est-à-dire des rouleaux dans lesquels le centre de l'enroulement du papier à distribuer est directement au contact de la tige support.The invention relates more particularly to distributors of paper intended to receive rolls without a core, i.e. rolls in which the center of the winding of the paper to be dispensed is directly in contact with the support rod.

De tels rouleaux sans mandrin permettent d'obtenir un enroulement plus serré et par conséquent une plus grande longueur de papier dans un même encombrement radial du rouleau.Such rolls without mandrel make it possible to obtain a winding tighter and therefore a greater length of paper in a same radial size of the roller.

De ce fait, les rouleaux sans mandrin doivent être utilisés dans des distributeurs spécifiques.Therefore, rollers without a core must be used in specific distributors.

Lorsque l'utilisateur souhaite dérouler une certaine longueur de papier, il provoque l'entraínement en rotation du rouleau. Si l'effort de traction qu'il exerce sur le papier est relativement énergique, le rouleau acquiert une certaine vitesse de rotation autour de la tige support et, si rien n'est prévu, l'énergie cinétique emmagasinée par le rouleau risque de provoquer un dévidage excédentaire du rouleau jusqu'à auto-rotation, au-delà de la longueur de papier souhaitée par l'utilisateur.When the user wishes to unroll a certain length of paper, it causes the rotation of the roller. If the effort of traction on paper is relatively strong, the roller acquires a certain speed of rotation around the support rod and, if nothing kinetic energy stored by the roller risks cause excess unwinding of the roll until auto-rotation, beyond the length of paper desired by the user.

L'invention a donc pour but de proposer des moyens simples et économiques permettant de freiner efficacement le rouleau pour éviter un tel excès de dévidage, les moyens de freinage ne devant toutefois pas imposer une résistance trop forte au dévidage volontaire de l'utilisateur et ne devant pas détériorer le rouleau de papier. La résistance doit être inférieure à la force de rupture de la prédécoupe.The object of the invention is therefore to propose simple and economical to effectively brake the roller to avoid such excess unwinding, the braking means however not having to impose too much resistance to voluntary user unwinding and not to damage the paper roll. Resistance must be less than the breaking force of the precut.

Par ailleurs, il est apparu nécessaire de déterminer avec une relative précision et surtout de maintenir la position axiale du rouleau en position de dévidage. En effet, lorsque l'utilisateur déroule le papier, son effort de traction est rarement parfaitement perpendiculaire à l'axe de rotation du rouleau, si bien que le rouleau tend à être décalé axialement sur sa tige support au point parfois d'être décalé axialement par rapport à l'ouverture du boítier au travers de laquelle le papier doit être distribué.Furthermore, it appeared necessary to determine with relative precision and above all to maintain the axial position of the roller in position unwinding. When the user unrolls the paper, his effort to traction is rarely perfectly perpendicular to the axis of rotation of the roller, so that the roller tends to be offset axially on its rod support sometimes to be offset axially with respect to the opening the box through which the paper is to be distributed.

Ce problème est tout particulièrement important lorsque le distributeur est prévu pour recevoir, sur la même tige support, un deuxième rouleau en position de stockage. Dans un tel distributeur, lorsque le rouleau en position de dévidage est épuisé, il suffit de décaler axialement le deuxième rouleau de la position de stockage vers la position de dévidage, ceci étant possible grâce au fait que les rouleaux sont du type sans mandrin.This problem is particularly important when the distributor is designed to receive, on the same support rod, a second roller in storage position. In such a distributor, when the roll in the feed position is exhausted, simply shift the axially second roll from the storage position to the unwinding position, this being possible thanks to the fact that the rollers are of the type without mandrel.

L'invention a donc aussi pour objet de proposer des moyens de blocage axial du rouleau en position de dévidage.The object of the invention is therefore also to propose means of axial locking of the roll in the unwinding position.

Dans ce but, l'invention propose un distributeur selon la revendication 1.For this purpose, the invention provides a dispenser according to claim 1.

La fente de distribution 16 est ici agencée vers le bas, sur la gauche du distributeur en regardant les figures, de telle sorte que la partie droite du distributeur 10 reçoit le rouleau en réserve 11S en position de stockage.The distribution slot 16 is here arranged downwards, on the left dispenser by looking at the figures, so that the right part the distributor 10 receives the reserve roll 11S in the storage position.

Lorsque le rouleau en position de dévidage est terminé, un mécanisme non représenté permet de déplacer axialement le rouleau de réserve le long de la tige support 14 jusqu'à la position de dévidage 11D, ceci sans nécessiter l'ouverture du couvercle. Le coulissement du rouleau de réserve n'est en effet pas entravé par un éventuel mandrin du rouleau épuisé qui empêcherait d'amener le rouleau de réserve en position de dévidage.When the roll in the feed position is finished, a mechanism not shown allows the roller to be moved axially reserve along the support rod 14 to the unwinding position 11D, this without requiring the opening of the cover. Roller sliding reserve is indeed not hampered by a possible mandrel of the roller exhausted which would prevent the reserve roll from being brought into the reeling.

La tige support 14 peut être montée de manière amovible dans le corps principal 12 du distributeur 10.The support rod 14 can be removably mounted in the main body 12 of the distributor 10.

Le corps principal 12 comporte une face arrière verticale plane 18 destinée à permettre son montage, par exemple contre un mur. La tige support 14, qui est agencée sensiblement au centre du distributeur 10, est rendue solidaire par ses deux extrémités aux deux parois latérales 20 verticales du corps principal 12. Cette tige est amovible ou non, pivotante ou non autour de l'une de ses extrémités.The main body 12 has a flat vertical rear face 18 intended to allow its mounting, for example against a wall. The rod support 14, which is arranged substantially in the center of the distributor 10, is made integral by its two ends with the two side walls 20 vertical of the main body 12. This rod is removable or not, pivoting or not around one of its ends.

A cet effet, la tige 14 comporte, à une première extrémité 22, un tronçon cylindrique 24 d'axe A2 transversal, perpendiculaire à l'axe A1 de la tige 14 et sensiblement horizontal, de telle sorte que l'extrémité 22 de la tige 14 présente, vue de dessus, une forme de T.To this end, the rod 14 has, at a first end 22, a cylindrical section 24 of transverse axis A2, perpendicular to the axis A1 of the rod 14 and substantially horizontal, so that the end 22 of the rod 14 has, seen from above, a T shape.

Les parois latérales 20 du distributeur 10 comportent, sur leurs faces internes 26, une gouttière 28 dont la forme en section par un plan longitudinal vertical est sensiblement celle d'un U ouvert verticalement vers le haut.The side walls 20 of the distributor 10 have, on their internal faces 26, a gutter 28 whose shape in section by a plane longitudinal vertical is substantially that of a U open vertically towards the top.

Le rebord vertical interne 30 de chacune des deux gouttières 28 comporte une encoche 32 dont la dimension selon la direction transversale est sensiblement égale au diamètre de la tige support 14.The internal vertical rim 30 of each of the two gutters 28 has a notch 32 whose dimension in the transverse direction is substantially equal to the diameter of the support rod 14.

Le tronçon cylindrique transversal 24 de l'extrémité 22 en forme de T de la tige 14 est donc susceptible d'être emboíté élastiquement, du haut vers le bas en regardant les figures, dans l'une ou l'autre des gouttières 28, la tige 14 étant alors reçue dans l'encoche 32 correspondante.The transverse cylindrical section 24 of the end 22 in the form of T of the rod 14 is therefore likely to be fitted elastically, from the top looking down at the figures, in one or other of the gutters 28, the rod 14 then being received in the corresponding notch 32.

L'extrémité opposée 34 de la tige support 14 est dépourvue de tronçon transversal mais elle est reçue au travers de l'encoche 32 de la gouttière opposée dans laquelle elle est maintenue par la simple action de son poids combinée avec celle du poids du rouleau, ou des rouleaux, lorsqu'il est monté sur la tige 14.The opposite end 34 of the support rod 14 is devoid of transverse section but it is received through the notch 32 of the opposite gutter in which it is held by the simple action of its weight combined with that of the weight of the roller, or rollers, when mounted on the rod 14.

Un tel mode de fixation de la tige 14 est particulièrement avantageux car il permet d'une part un maintien simple et efficace de celle-ci et, d'autre part, il empêche la tige 14 de pouvoir pivoter sur elle-même autour de son axe A1. Par ailleurs, en choisissant un tronçon transversal 24 de forme cylindrique et une gouttière 28 de forme correspondante, la tige 14 est articulée autour de l'axe A2 du tronçon transversal 24 par rapport au corps principal 12 du distributeur. Such a method of fixing the rod 14 is particularly advantageous because it allows on the one hand a simple and effective maintenance thereof and, on the other hand, it prevents the rod 14 from being able to pivot on itself around its axis A1. Furthermore, by choosing a transverse section 24 of cylindrical shape and a gutter 28 of corresponding shape, the rod 14 is articulated around the axis A2 of the transverse section 24 relative to the main body 12 of the distributor.

Ainsi, lorsque la tige 14 est montée sur le distributeur 10, il est possible de monter les rouleaux de papier sur la tige 14 en faisant pivoter celle-ci autour de son extrémité 22 en forme de T de manière à introduire les rouleaux par l'extrémité opposée 34, sans qu'il soit nécessaire de démonter entièrement la tige 14.Thus, when the rod 14 is mounted on the distributor 10, it is possible to mount paper rolls on rod 14 by rotating this around its T-shaped end 22 so as to introduce the rollers by the opposite end 34, without the need to completely dismantle the rod 14.

En tout état de cause, le montage et le démontage, le remplacement complet de la tige 14 restent très simples à effectuer, par simple emboítement et déboítement du tronçon transversal 24.In any event, assembly and disassembly, replacement rod 14 remain very simple to perform, by simple fitting and dislodging of the transverse section 24.

Selon un premier aspect de l'invention, l'exemple de réalisation qui est illustré aux figures 1 à 4 comporte une tige 14 qui est munie d'une excroissance radiale 36 qui permet de freiner le rouleau de papier lors du dévidage.According to a first aspect of the invention, the embodiment which is illustrated in Figures 1 to 4 has a rod 14 which is provided with a radial protuberance 36 which makes it possible to brake the paper roll during the reeling.

L'excroissance radiale 36 s'étend sur une longueur axiale limitée, inférieure à la dimension du rouleau de papier selon cette direction, et elle est agencée sensiblement au milieu du rouleau lorsque celui-ci est en position de dévidage 11D sur la tige 14.The radial protuberance 36 extends over a limited axial length, smaller than the size of the paper roll in this direction, and it is arranged substantially in the middle of the roller when the latter is in unwinding position 11D on the rod 14.

Il n'est en effet pas prévu, dans le mode de réalisation représenté sur les figures, d'excroissance de la tige 14 correspondant à la position de stockage du rouleau.It is indeed not provided, in the embodiment shown in the figures, protrusion of the rod 14 corresponding to the position of roller storage.

L'agencement en position centrale de l'excroissance 36 tend à provoquer un centrage du rouleau lorsqu'il se dévide, évitant qu'il ne se déplace trop selon la direction axiale de la tige 14. Il assure ainsi un freinage contrôlé en position centrale. Le rouleau ne vient pas frotter sur les parties latérales. Le rouleau reste ainsi en regard de la fente de distribution 16.The arrangement in the central position of the projection 36 tends to cause the roll to be centered when it unwinds, preventing it from moves too much in the axial direction of the rod 14. It thus ensures a braking controlled in central position. The roller does not rub on the side parts. The roller thus remains opposite the slot of distribution 16.

Par ailleurs, dans l'exemple de réalisation représenté sur les figures 1 à 4, l'excroissance radiale 36 n'est pas symétrique autour de l'axe A1. En effet, elle ne s'étend que sur un angle inférieur à 180° autour de l'axe A1, et elle est orientée vers le haut de telle sorte que, en coupe selon un plan transversal, la section de la tige 14 est sensiblement de forme oblongue, allongée vers le haut par rapport à l'axe A1.Furthermore, in the embodiment shown in the figures 1 to 4, the radial projection 36 is not symmetrical about the axis A1. In indeed, it only extends over an angle less than 180 ° around the axis A1, and it is oriented upwards so that, in section along a plane transverse, the section of the rod 14 is substantially oblong, elongated upwards with respect to the axis A1.

L'excroissance radiale 36 présente, en vue de profil selon une direction horizontale, tel que représenté à la figure 3, une surface bombée convexe 38 raccordée symétriquement, de part et d'autre le long de la direction axiale, par des surfaces courbes concaves 40 avec la surface cylindrique de la tige 14. Ainsi, la variation de section transversale de la tige 14 au niveau de l'excroissance 36 est progressive et continue.The radial protuberance 36 presents, in profile view according to a horizontal direction, as shown in Figure 3, a curved surface convex 38 connected symmetrically on either side along the axial direction, by concave curved surfaces 40 with the surface cylindrical of the rod 14. Thus, the variation in cross section of the rod 14 at the projection 36 is progressive and continuous.

Dans l'exemple de réalisation qui est représenté sur les figures 1 à 4, l'excroissance radiale 36 est dirigée vers le haut du fait d'une part de la prise en compte du poids des rouleaux qui s'exerce du haut vers le bas et, d'autre part, du fait que l'ouverture 16 permet à l'utilisateur de dérouler le rouleau de papier en tirant sur celui-ci, sensiblement verticalement vers le bas, à l'opposé de l'excroissance radiale 36.In the embodiment which is represented in FIGS. 1 to 4, the radial protuberance 36 is directed upwards on the one hand from the taking into account the weight of the rollers which is exerted from top to bottom and, on the other hand, the fact that the opening 16 allows the user to unwind the roll of paper by pulling it, substantially vertically towards the bottom, opposite the radial protrusion 36.

Ainsi, la combinaison de ces deux actions provoque un frottement suffisamment important du rouleau sur l'excroissance radiale 36 pour que celle-ci provoque le freinage du rouleau par frottement.So the combination of these two actions causes friction large enough of the roller on the radial projection 36 so that this causes the braking of the roller by friction.

L'excroissance radiale 36 étant dépourvue de toute surface anguleuse, elle ne risque pas de détériorer le rouleau de papier.The radial protuberance 36 being devoid of any surface angular, there is no risk of damaging the paper roll.

Selon un second aspect de l'invention, le distributeur 10 comporte des moyens pour assurer le blocage du rouleau selon la direction axiale en position de dévidage.According to a second aspect of the invention, the distributor 10 comprises means for locking the roller in the axial direction in wire feed position.

A cet effet, la tige 14 comporte un bossage tronconique 48 qui est agencé sensiblement au milieu de la tige 14, entre les positions de stockage et de dévidage du rouleau.To this end, the rod 14 has a frustoconical boss 48 which is arranged substantially in the middle of the rod 14, between the storage positions and unwinding the roll.

La base 50 du bossage tronconique 48 forme une surface transversale d'épaulement 50 qui empêche le rouleau de revenir de sa position de dévidage vers sa position de stockage, ce qui l'oblige à rester en regard de la fente de distribution 16.The base 50 of the frustoconical boss 48 forms a surface transverse shoulder 50 which prevents the roller from returning from its reeling position to its storage position, which forces it to remain next to the distribution slot 16.

Au contraire, la surface conique du bossage 48 permet au rouleau de passer facilement de sa position de stockage à sa position de dévidage.On the contrary, the conical surface of the boss 48 allows the roller easily move from its storage position to its unwinding position.

Pour bloquer le rouleau selon l'autre sens, on peut prévoir que, comme dans le mode de réalisation représenté aux figures 1 à 4, le rouleau vienne simplement en appui contre la gouttière 28.To block the roller in the other direction, it can be provided that, as in the embodiment shown in Figures 1 to 4, the roller simply press against the gutter 28.

Dans le premier exemple de réalisation de la tige 14 qui est représenté sur les figures 1 à 4, la tige 14 est réalisée venue de matière en une seule pièce.In the first embodiment of the rod 14 which is shown in Figures 1 to 4, the rod 14 is made integrally in one piece.

Au contraire, dans l'exemple de réalisation qui est représenté sur la figure 5, l'extrémité 22 en forme de T de la tige 14 est réalisée sous la forme d'une pièce rapportée 42.On the contrary, in the exemplary embodiment which is represented on the FIG. 5, the T-shaped end 22 of the rod 14 is produced under the shape of an insert 42.

L'extrémité rapportée 42 en forme de T comporte une cheville 44 d'axe A1 destinée à être introduite dans un orifice 45 correspondant de l'extrémité de la tige 14. La fixation de la cheville 44 dans l'orifice 45 peut être réalisée par tout moyen approprié, par exemple par vissage, par collage ou par emboítement à force.The T-shaped attached end 42 has a dowel 44 of axis A1 intended to be introduced into a corresponding orifice 45 of the end of the rod 14. The fixing of the pin 44 in the orifice 45 can be carried out by any suitable means, for example by screwing, by bonding or interlocking by force.

De plus, dans ce second mode de réalisation, on a prévu des moyens qui permettent d'assurer un meilleur guidage latéral du rouleau en position de dévidage selon la direction axiale de la tige 14. In addition, in this second embodiment, provision has been made for means which allow better lateral guidance of the roller in unwinding position in the axial direction of the rod 14.

A cet effet, une rondelle annulaire transversale 46 est montée sur la cheville 44 de l'extrémité rapportée 42 pour immobiliser le rouleau selon un premier sens, et notamment pour éviter que celui-ci ne puisse venir frotter contre la paroi latérale 20 du corps principal 12 et contre la gouttière 28.For this purpose, a transverse annular washer 46 is mounted on the pin 44 of the attached end 42 to immobilize the roller according to a first sense, and in particular to prevent it from coming to rub against the side wall 20 of the main body 12 and against the gutter 28.

On a représenté sur les figures 6 à 8 un troisième mode de réalisation d'un distributeur qui comporte des moyens perfectionnés de freinage du rouleau. Des éléments identiques ou similaires à ceux décrits précédemment seront désignés par les mêmes chiffres de référence.FIGS. 6 to 8 show a third mode of realization of a distributor which includes means advanced roller braking. Identical or similar elements to those described above will be designated by the same numbers of reference.

Comme dans les deux précédents modes de réalisation, la tige support 14 comporte un bossage tronconique 48 qui est agencé sensiblement au centre de la tige 14 pour empêcher à un rouleau de passer de sa position de dévidage à sa position de stockage, c'est-à-dire selon une première direction axiale.As in the previous two embodiments, the rod support 14 has a frustoconical boss 48 which is arranged substantially in the center of the rod 14 to prevent a roller from passing from its unwinding position to its storage position, that is to say according to a first axial direction.

Toutefois, ce troisième mode de réalisation de l'invention se distingue par le fait que les moyens de freinage du rouleau servent en même temps à bloquer le rouleau selon la direction opposée.However, this third embodiment of the invention is distinguishes by the fact that the braking means of the roller serve the same time to block the roller in the opposite direction.

En effet, le distributeur 10 comporte un patin de freinage 52 qui est monté coulissant sur la tige support 14, du côté de la face transversale 54 du rouleau qui est opposée à la face transversale 56 par laquelle le rouleau 11D coopère avec la base 50 du bossage tronconique 48. Le patin de freinage 52 est sollicité axialement en appui contre la face correspondante 54 du rouleau et il est immobile en rotation autour de l'axe A1.In fact, the distributor 10 includes a brake shoe 52 which is sliding mounted on the support rod 14, on the side of the transverse face 54 of the roller which is opposite to the transverse face 56 by which the roller 11D cooperates with the base 50 of the frustoconical boss 48. The skid of braking 52 is axially biased in abutment against the corresponding face 54 of the roller and it is stationary in rotation about the axis A1.

Ainsi, par frottement contre la face 54, le patin 52 assure le freinage du rouleau, et, simultanément, il pousse le rouleau en appui contre la base 50 du bossage tronconique 48 ce qui permet de déterminer de manière très fiable sa position dans le distributeur 10.Thus, by friction against the face 54, the shoe 52 ensures the braking of the roller, and simultaneously pushes the roller against the base 50 of the frustoconical boss 48 which makes it possible to determine very reliably its position in the distributor 10.

Dans l'exemple de réalisation illustré, le patin 52 est réalisé sous la forme d'une plaque qui s'étend dans un plan transversal, qui est allongée radialement selon un diamètre du rouleau et qui est de faible largeur.In the illustrated embodiment, the shoe 52 is produced under the form of a plate which extends in a transverse plane, which is elongated radially along a diameter of the roller and which is of small width.

Le patin 52, qui coulisse axialement sur la tige 14, est immobilisé par rapport au corps principal 12 du distributeur 10 par deux pattes 58 qui s'étendent à chacune des extrémités radiales du patin 52, axialement dans la direction à celle du rouleau. Les pattes 58 sont reçues à coulissement axial chacune dans une lumière correspondante 60 formée dans une plaque de garde 62 qui est fixe dans le distributeur 10.The shoe 52, which slides axially on the rod 14, is immobilized relative to the main body 12 of the distributor 10 by two legs 58 which extend at each of the radial ends of the shoe 52, axially in the direction to that of the roller. The legs 58 are received with axial sliding each in a corresponding lumen 60 formed in a plate of guard 62 which is fixed in the distributor 10.

La plaque de garde 62 représentée sur les figures présente sensiblement la même forme que le patin de freinage 52 et elle peut être soit réalisée venue de matière avec la tige 14, soit réalisé sous la forme d'une pièce rapportée à la manière de la rondelle annulaire 46 du deuxième mode de réalisation précédemment décrit.The guard plate 62 shown in the figures presents substantially the same shape as the brake shoe 52 and it can be either produced integrally with the rod 14, or produced in the form of an insert in the manner of the annular washer 46 of the second previously described embodiment.

Un ressort de compression 64 est agencé entre la plaque de garde 60 et le patin de freinage 52 de manière à solliciter ce dernier en appui contre la face latérale transversale 54 du rouleau 11D. Les pattes 58 comportent des moyens de butée qui empêchent que le patin 52 ne s'écarte trop de la plaque de garde 62 lorsqu'il n'y a pas de rouleau en position de dévidage.A compression spring 64 is arranged between the guard plate 60 and the brake shoe 52 so as to urge the latter to bear against the transverse lateral face 54 of the roller 11D. Legs 58 have stop means which prevent the shoe 52 from moving away too much of the guard plate 62 when there is no roller in the position of reeling.

Bien entendu, d'autres solutions sont envisageables pour assurer l'immobilisation en rotation du patin de freinage. Ainsi, le patin 52 peut comporter une douille cannelée montée coulissante sur une portion cannelée de la tige 14.Of course, other solutions are possible to ensure immobilization of the brake shoe in rotation. Thus, the pad 52 can have a grooved sleeve slidingly mounted on a portion grooved rod 14.

Le patin 52 présente l'avantage selon lequel sa surface de contact avec le rouleau est proportionnelle au diamètre du rouleau. Ainsi, la force de freinage exercée par le patin diminue avec le diamètre du rouleau. Or, lorsque le diamètre du rouleau diminue, son inertie et donc la force nécessaire pour le freiner diminuent aussi. De la sorte, la force de freinage exercée par le patin 52 sur le rouleau est toujours adaptée à ce qui est nécessaire.The shoe 52 has the advantage that its contact surface with the roller is proportional to the diameter of the roller. So the strength brake applied by the shoe decreases with the diameter of the roller. Gold, when the diameter of the roller decreases, its inertia and therefore the force necessary to brake it also decrease. In this way, the braking force exerted by the pad 52 on the roller is always adapted to what is necessary.

Par ailleurs, dans ce troisième mode de réalisation, la tige de support 14 est articulée sur le corps principal 12 du distributeur 10 par une extrémité en forme de chape dont chaque branche est percée d'un orifice d'axe A2 pour le passage d'une tige d'articulation portée par le distributeur 10.Furthermore, in this third embodiment, the rod of support 14 is articulated on the main body 12 of the distributor 10 by a clevis-shaped end, each branch of which has an orifice of axis A2 for the passage of an articulation rod carried by the distributor 10.
