A pair of coaxial hooks is provided at the level of cross arms. Each hook is engaged on each fixation bar and housed in such a way that the tool is conveniently supported by the frame.

Description

La présente invention concerne un cadre porte-outil à caractère polyvalent destiné à équiper un chargeur, notamment un chargeur frontal à usage agricole monté sur un tracteur.The present invention relates to a versatile toolholder frame intended to equip a loader, including a front loader for agricultural use mounted on a tractor.

Un tel chargeur, à commande hydraulique, est conçu pour pouvoir manipuler des matériaux divers dans une exploitation agricole, tels que de la paille, du foin, du fumier, de la terre, des engrais, des céréales, des betteraves, des pommes de terre, de l'ensilage, notamment.Such a hydraulically operated loader is designed to handle various materials on a farm, such as straw, hay, manure, soil, fertilizer, cereals, beets, potatoes , silage, in particular.

A cet effet, l'exploitant doit avoir à disposition divers outils amovibles, adaptés chacun à des travaux et/ou des matériaux spécifiques.To this end, the operator must have available various removable tools, each adapted to specific work and / or materials.

Ces outils sont en particulier des bennes, des griffes, des grappins, des lames, des fourches, des transpalettes, ou des outils combinés, tels que des bennes à griffes par exemple.These tools are in particular skips, claws, grapples, blades, forks, pallet trucks, or combined tools, such as clamshells, for example.

Le cadre porte-outil fixé au bout des bras du chargeur et la face dorsale de l'outil (face tournée vers le chargeur) possèdent des moyens d'accouplement complémentaires dont la conception permet le changement rapide de l'outil.The tool holder frame attached to the end of the loader arms and the back face of the tool (face facing the loader) have complementary coupling means whose design allows the rapid change of the tool.

Une difficulté rencontrée par les constructeurs et leurs clients utilisateurs réside dans le fait qu'il n'y a pas de normalisation en la matière, de sorte qu'un outil provenant d'un constructeur donné n'est pas forcément adaptable sur un ensemble chargeur/cadre porte-outil provenant de chez un autre constructeur.A difficulty encountered by manufacturers and their user customers lies in the fact that there is no standardization in the field, so that a tool from a given manufacturer is not necessarily adaptable on a loader assembly / tool holder frame from another manufacturer.

Le choix d'un usager souhaitant s'équiper en nouveaux outils se trouve par conséquent limité dans la mesure où il ne peut acheter que des modèles adaptables sur le chargeur qu'il a en sa possession.The choice of a user wishing to equip himself with new tools is therefore limited insofar as he can only buy adaptable models on the charger he has in his possession.

Inversement, s'il souhaite changer de chargeur, il peut être dissuadé, pour des raisons pécuniaires, d'acheter un modèle sur lequel il ne pourra pas adapter les outils préalablement achetés, dont il dispose.Conversely, if he wants to change charger, he can be dissuaded, for pecuniary reasons, to buy a model on which he can not adapt the previously purchased tools, which he has.

En pratique, il existe en Europe trois grandes catégories de systèmes d'accouplement, correspondant à des standards de fait.In practice, there are three main categories of coupling systems in Europe, corresponding to de facto standards.

Un premier standard, commercialisé sous la marque "MAILLEUX", est caractérisé en ce que le cadre porte-outil comporte une paire de mains d'accrochage identiques de section approximativement en "U", dont l'ouverture est dirigée vers le haut, disposées coaxialement et symétriquement de part et d'autre du plan vertical et longitudinal médian du cadre porte-outil, tandis que la face dorsale de l'outil est pourvue, en partie haute, d'une paire de barreaux coaxiaux, ainsi dimensionnés et positionnés que chacun d'eux peut s'emboîter et se loger à l'intérieur d'une main d'accrochage. Chaque barreau est monté entre deux ferrures, dont l'une se prolonge vers le bas, et présente un orifice de verrouillage et une encoche. Le cadre porte-outil est équipé d'un dispositif de verrouillage comprenant une paire de broches mobiles en translation, aptes à venir s'insérer chacune dans l'un de ces orifices, et assurer la fixation de l'outil sur le cadre porte-outil. L'encoche sert de zone d'appui de la partie basse de l'outil contre des butées appropriées dont est muni le cadre porte-outil.A first standard, marketed under the trademark "MAILLEUX", is characterized in that the tool holder frame comprises a pair of identical hooking hands of approximately "U" -shaped section, whose opening is directed upwards, arranged coaxially and symmetrically on both sides of the vertical and longitudinal median plane of the tool frame, while the dorsal surface of the tool is provided, at the top, with a pair of bars coaxial, so dimensioned and positioned that each of them can fit and be housed inside a gripping hand. Each bar is mounted between two fittings, one of which extends downwards, and has a locking hole and a notch. The tool-holder frame is equipped with a locking device comprising a pair of pins movable in translation, each adapted to fit into one of these orifices, and ensuring the attachment of the tool to the frame-holder tool. The notch serves as a bearing area of the lower part of the tool against appropriate stops which is provided with the tool holder frame.

Selon les modèles, le dispositif de verrouillage est commandé manuellement, à l'aide d'un levier de manoeuvre, ou hydrauliquement, au moyen d'un vérin, comme cela est décrit par exemple dans le document FR 2 776 316 , qui décrit un porte-outil selon le préambule de la revendication 1.According to the models, the locking device is controlled manually, using an operating lever, or hydraulically, by means of a jack, as described for example in the document FR 2,776,316 which describes a tool holder according to the preamble of claim 1.

Un deuxième standard, notamment usité sur le marché allemand, et communément désigné "DGS", est caractérisé en ce que le cadre porte-outil comporte une paire de barreaux d'accrochage coaxiaux disposés symétriquement de part et d'autre du plan vertical et longitudinal médian du cadre porte-outil, tandis que la face dorsale est pourvue, en partie haute, d'une paire de crochets coaxiaux, dont l'ouverture est dirigée vers le bas, ainsi dimensionnés et positionnés que chacun d'eux peut s'engager sur un barreau d'accrochage, et l'emprisonner.A second standard, particularly used on the German market, and commonly referred to as "DGS", is characterized in that the tool holder frame comprises a pair of coaxial hooking bars arranged symmetrically on either side of the vertical and longitudinal plane. middle of the tool holder frame, while the dorsal surface is provided, in the upper part, a pair of coaxial hooks, whose opening is directed downwards, so dimensioned and positioned that each of them can engage on a hanging bar, and imprison him.

Comme pour le premier standard, la face dorsale de l'outil comporte une paire de ferrures présentant un orifice de verrouillage, et une zone d'appui pour sa partie basse.As for the first standard, the back face of the tool comprises a pair of fittings having a locking hole, and a support zone for its lower part.

Il y a en quelque sorte une inversion des organes d'accrochage, les organes "mâles" (barreaux) étant portés par l'outil dans le premier standard, et par le cadre porte-outil dans le deuxième standard, tandis que les organes "femelles" (mains ou crochets) sont portés par le cadre porte-outil dans le premier standard, et par l'outil dans le deuxième standard.There is somehow an inversion of the attachment members, the "male" members (bars) being carried by the tool in the first standard, and the tool holder in the second standard, while the organs " females "(hands or hooks) are carried by the tool holder in the first standard, and by the tool in the second standard.

De plus, les orifices de verrouillage, et corrélativement les broches qui y pénètrent, ont des diamètres différents; le diamètre de ces orifices est de 30 mm pour le premier standard et de 20 mm pour le deuxième.In addition, the locking holes, and correlatively the pins that penetrate, have different diameters; the diameter of these orifices is 30 mm for the first standard and 20 mm for the second.

Un troisième standard, notamment usité sur le marché suédois, et communément désigné "SMS", a une structure globalement similaire à celle du deuxième standard, les barreaux étant portés par le cadre porte-outil, et les crochets par l'outil. Toutefois, chacun des orifices de verrouillage est constitué non pas par un alésage percé dans une ferrure, mais par un oeillet fixé à la base d'une tige plate dont la partie supérieure porte un crochet. Selon ce troisième standard, chaque crochet se trouve donc dans le même plan vertical et longitudinal qu'un orifice de verrouillage, alors que selon les deux premiers standards, les moyens d'accrochage (barreaux ou crochets) sont décalés latéralement, vers l'extérieur, par rapport aux ferrures dans lesquelles sont percés les orifices de verrouillage.A third standard, particularly used on the Swedish market, and commonly referred to as "SMS", has a structure similar to that of the second standard, the bars being carried by the tool holder frame, and the hooks by the tool. However, each of the locking holes is constituted not by a bore drilled in a fitting, but by an eyelet fixed to the base of a flat rod whose upper part carries a hook. According to this third standard, each hook is therefore in the same vertical and longitudinal plane as an orifice of locking, while according to the first two standards, the hooking means (bars or hooks) are offset laterally outwardly relative to the fittings in which are drilled the locking holes.

En outre, les crochets des second et troisièmes standards, tous deux en forme de "U" renversé, ont des largeurs différentes; corrélativement, les barreaux d'accrochage ont des diamètres différents, de valeur 40 mm pour le second standard, et 60 mm pour le troisième.In addition, the hooks of the second and third standards, both U-shaped overturned, have different widths; correspondingly, the fastening bars have different diameters, of value 40 mm for the second standard, and 60 mm for the third.

Les barreaux d'accrochage du premier standard ont, quant à eux, un diamètre ayant une valeur de 50 mm.The snap bars of the first standard have, for their part, a diameter having a value of 50 mm.

Par ailleurs, les valeurs des écartements mutuels -ou entraxes- des organes de fixation et des orifices de verrouillage d'une même paire sont différentes pour chacun de ces trois standards.Furthermore, the values of the mutual spacings - or center distances - of fasteners and locking holes of the same pair are different for each of these three standards.

La présente invention a pour but de résoudre ces problèmes d'incompatibilité en proposant un cadre porte-outil capable d'être accouplé à un outil conforme au premier standard précité, et au moins à l'un des deux autres, ce cadre porte-outil étant néanmoins de conception relativement simple, d'un prix de revient acceptable, et commode d'utilisation.The object of the present invention is to solve these incompatibility problems by proposing a tool-holder frame capable of being coupled to a tool conforming to the aforementioned first standard, and at least to one of the other two, this tool-holder frame. nevertheless being of relatively simple design, an acceptable cost price, and convenient to use.

Conformément à l'invention, le cadre porte-outil comporte, en outre, au moins une paire de barreaux d'accrochage coaxiaux disposés symétriquement de part et d'autre du plan vertical et longitudinal médian du cadre porte-outil, qui autorisent l'accouplement de ce dernier à un outil satisfaisant à au moins un autre standard de montage, dit "deuxième standard", dont la face dorsale est pourvue, en partie haute, d'une paire de crochets coaxiaux, dont l'ouverture est dirigée vers le bas, ainsi dimensionnés et positionnés que chacun d'eux peut s'engager sur un barreau d'accrochage, et l'emprisonner, de telle sorte que l'outil conforme au deuxième standard se trouve alors convenablement supporté par le cadre porte-outilAccording to the invention, the tool holder frame further comprises at least one pair of coaxial hooking bars arranged symmetrically on both sides of the vertical and longitudinal median plane of the tool holder frame, which allow the coupling of the latter to a tool satisfying at least one other mounting standard, called "second standard", whose dorsal face is provided, in the upper part, a pair of coaxial hooks, the opening is directed towards the down, so sized and positioned that each of them can engage on a hooking bar, and to trap it, so that the tool conforming to the second standard is then properly supported by the tool-holder frame

La figure 1 représente un tracteur agricole TA équipé d'un chargeur CH de type connu, comprenant un brancard BR dont les mouvements de levage et d'abaissement sont assurés par un vérin hydraulique VL dit vérin de levage.The figure 1 represents an agricultural tractor TA equipped with a CH loader of known type, comprising a BR stretcher whose lifting and lowering movements are provided by a hydraulic cylinder VL said lifting cylinder.

A l'extrémité libre du brancard BR est monté un cadre porte-outil 1 qui est articulé à sa base, son pivotement étant assuré par un autre vérin hydraulique VB dit vérin de bennage ou vérin de cavage.At the free end of the BR stretcher is mounted a tool holder frame 1 which is articulated at its base, its pivoting being provided by another hydraulic cylinder VB said tipping cylinder or digging cylinder.

Toujours de manière connue, un jeu de biellettes BC assure la liaison entre la tige de ce vérin VB et le cadre porte-outil 1.Still in a known manner, a set of connecting rods BC ensures the connection between the rod of this jack VB and the tool holder frame 1.

Ce cadre porte-outil est pourvu en partie haute d'une paire de mains MA, en forme de gouttières ouvertes vers le haut, destinées à assurer son accrochage sur un outil 2, par exemple une benne.This tool holder frame is provided in the upper part of a pair of hands MA , shaped gutters open upwards, intended to ensure its attachment to a tool 2, for example a bucket.

Cet outil 2 comporte sur sa face dorsale des moyens d'accrochage et de retenue qui consistent notamment en une paire de barreaux TA aptes à s'engager (par un mouvement du haut vers le bas) sur les mains MA ; de plus, des ferrures FE situées au dos de l'outil 2 présentent des orifices de verrouillage OV pouvant être traversés des broches de verrouillage portées par le cadre porte-outil 1, de manière à assurer la solidarisation de l'outil sur ce cadre porte-outil.This tool 2 has on its dorsal face means of attachment and retention which consist in particular of a pair of bars TA able to engage (by a movement from top to bottom) on hands MA ; in addition, FE fittings located on the back of the tool 2 have OV locking holes through which the locking pins carried by the tool holder frame 1 can pass, so as to ensure the attachment of the tool to this door frame -tool.

On notera également que les ferrures FE présentent à leur base une zone d'appui ZA, en forme d'encoche, apte à venir prendre appui contre une traverse BA s'étendant transversalement à la base du cadre 1.It will also be noted that the FE fittings have at their base a bearing zone ZA , in the form of a notch, able to bear against a crossbar BA extending transversely to the base of the frame 1.

Dans la suite de la description, et dans les revendications, on désignera par "direction longitudinale" la direction horizontale correspondant à la direction d'avance du tracteur (située dans le plan de la feuille de dessin de la figure 1) et par "direction transversale" la direction perpendiculaire à la direction longitudinale (perpendiculaire au plan de la feuille).In the remainder of the description, and in the claims, the term "longitudinal direction" will be referred to as the horizontal direction corresponding to the direction of travel of the tractor (located in the plane of the drawing sheet of the figure 1 ) and "transverse direction" the direction perpendicular to the longitudinal direction (perpendicular to the plane of the sheet).

En référence à la figure 2, nous allons maintenant décrire la structure du cadre porte-outil conforme à l'invention.With reference to the figure 2 , we will now describe the structure of the tool holder frame according to the invention.

Ce cadre porte-outil 1a une configuration généralement symétrique par rapport à plan vertical longitudinal médian.This tool holder frame 1 has a generally symmetrical configuration with respect to the median longitudinal vertical plane.

Il comprend à ses extrémités latérales une paire de plaques métalliques 3, 4 reliées les unes aux autres par des entretoises appropriées de manière à constituer une paire de flasques solidaires l'un de l'autre.It comprises at its lateral ends a pair of metal plates 3, 4 connected to each other by appropriate spacers so as to form a pair of flanges integral with each other.

Les deux flasques sont fixés par soudage aux extrémités d'une paire de traverses haute 5 et basse 6, lesquelles sont constituées par des tiges cylindriques métalliques.The two flanges are fixed by welding at the ends of a pair of high and low crosspieces 6, which consist of cylindrical metal rods.

On a désigné par les références X-X' et Y-Y', respectivement, les axes des traverses 5 et 6. X-X ' and Y-Y' respectively denote the axes of the crosspieces 5 and 6.

Par ailleurs, les deux flasques sont reliés l'un à l'autre par une tige 30 située en dessous de la traverse supérieure 5, d'axe également horizontal et transversal W-W'.Furthermore, the two flanges are connected to each other by a rod 30 located below the upper cross member 5, also horizontal axis and transverse W-W ' .

La traverse supérieure 5 possède des extrémités en forme de manchons 50 qui sont fixés aux flasques intérieurs 4.The upper crossmember 5 has sleeve-like ends 50 which are fixed to the inner flanges 4.

Chaque manchon 50 est solidaire d'une plaquette 51 qui s'étend verticalement vers le haut et possède des chants chanfreinés inclinés 510, respectivement 511, qui lui confèrent la forme d'un trapèze.Each sleeve 50 is integral with a plate 51 which extends vertically upwards and has inclined chamfered edges 510, respectively 511, which give it the shape of a trapezium.

Entre chacun des jeux de flasques 3-4 est disposé un levier 7 qui est articulé à sa base autour de la tige 30.Between each of the sets of flanges 3-4 is a lever 7 which is articulated at its base around the rod 30.

Sur la vue de la figure 2, dans un but de meilleure lisibilité, seul l'un de ces deux leviers a été représenté, dans une position démontée et est visible en haut et à droite de la figure.On the view of the figure 2 , for the sake of better legibility, only one of these two levers has been shown in a disassembled position and is visible at the top right of the figure.

Un levier identique, prévu sur la partie gauche du dessin, n'est pas représenté.An identical lever, provided on the left side of the drawing, is not shown.

La vue de détail éclatée qui est détachée de la figure, permet de constater que le levier 7 comprend un corps arqué 70 dont la base est traversée par un alésage transversal 71, lequel reçoit la tige d'articulation 30.The exploded detail view which is detached from the figure, allows to note that the lever 7 comprises an arched body 70 whose base is traversed by a transverse bore 71, which receives the hinge rod 30.

A son extrémité supérieure, le levier porte une gouttière 700, qui constitue la main d'accrochage MA dont il a été fait état plus haut.At its upper end, the lever carries a gutter 700, which is the attachment hand MA which has been mentioned above.

La gouttière 700 a approximativement la forme générale d'un "U" dont l'ouverture est dirigée vers le haut.The trough 700 is approximately the general shape of a "U" whose opening is directed upwards.

En partie haute, le levier 7 est traversé par un alésage transversal 72 dans lequel peut s'engager une tige 52 dont une extrémité (tournée vers la droite de la figure) porte une manette de préhension 53, tandis que son autre extrémité est susceptible de s'engager, après avoir traversé l'alésage 72 dans un perçage 500 prévu dans le manchon 50.In the upper part, the lever 7 is traversed by a transverse bore 72 in which can engage a rod 52, one end (facing to the right of the figure) carries a handle 53, while its other end is likely to engage, after passing through the bore 72 in a bore 500 provided in the sleeve 50.

Ce manchon a par conséquent une forme tubulaire.This sleeve therefore has a tubular shape.

Bien entendu, la longueur de la tige 52 est supérieure à l'écartement mutuel du jeu de plaques 3 et 4.Of course, the length of the rod 52 is greater than the mutual spacing of the set of plates 3 and 4.

Comme on le comprend aisément à la simple observation de la figure 2, le levier 7 étant articulé sur la tige d'articulation 30, elle peut basculer vers le bas entre les flasques 3 et 4 ; dans ce cas, si on introduit la tige 52 de l'extérieur vers l'intérieur du cadre porte-outil à travers une ouverture appropriée prévue en partie haute de la plaque 3, on peut faire pénétrer l'extrémité libre de la tige 52 dans le manchon 50.As is easily understood by simply observing the figure 2 the lever 7 being articulated on the hinge pin 30, it can swing down between the flanges 3 and 4; in this case, if the rod 52 is inserted from the outside towards the inside of the tool-holder frame through an appropriate aperture provided in the upper part of the plate 3, the free end of the rod 52 can be penetrated into the sleeve 50.

Des moyens appropriés non représentés, sont prévus pour assurer le blocage de cette tige 52 dans cette position en foncée, représentée sur la figure 2.Suitable means not shown, are provided to ensure the locking of this rod 52 in this dark position, shown on the figure 2 .

Comme on le verra plus tard, dans ce cas, les deux tiges 52 servent de barreaux d'accrochage pour un outil conforme Ă  un second standard.As will be seen later, in this case, the two rods 52 serve as hooking bars for a tool according to a second standard.

Si au contraire, le levier pivotant 7 se trouve dans une position dressée de telle sorte que son alésage 72 se trouve centré sur l'axe X-X', l'introduction de la tige 52 dans cet alésage 72 puis dans le perçage du manchon 50 a pour effet d'assurer le maintien du levier 7 et, corrélativement, de la main 700 dans sa position dressée ; il s'agit d'une position active dans laquelle la main 700 est adaptée pour recevoir un barreau d'accrochage dont est pourvu un outil conforme au premier standard.If on the contrary, the pivoting lever 7 is in an erect position so that its bore 72 is centered on the axis X-X ' , the introduction of the rod 52 in the bore 72 and in the drilling of the sleeve 50 a for effect to maintain the lever 7 and, correspondingly, the hand 700 in its erect position; it is an active position in which the hand 700 is adapted to receive a gripping bar which is provided with a tool complies with the first standard.

A la partie inférieure du cadre porte-outil 1 est installé un dispositif de verrouillage 8 qui, de manière connue, comprend un levier de manoeuvre 81 adapté pour assurer les déplacements en translation axiale, suivant un axe référencé Z-Z', de deux tiges de verrouillage coaxiales 80, via un jeu de biellettes 811.At the lower part of the tool holder frame 1 is installed a locking device 8 which, in a known manner, comprises an operating lever 81 adapted to provide displacements in axial translation, along an axis referenced Z-Z ' , of two locking rods. coaxial 80, via a set of rods 811.

Dans un autre mode de réalisation possible de l'invention, ces déplacements peuvent être commandés par un vérin hydraulique.In another possible embodiment of the invention, these displacements can be controlled by a hydraulic cylinder.

Le levier 81 est coudé en partie inférieure ; il est articulé autour d'un axe 810 sur une plaque 62 qui est portée par un étrier 60, en forme de "U" retourné, dont les branches latérales sont fixées, par exemple par soudage, sur le dessus de la traverse basse 6.The lever 81 is bent at the bottom; it is articulated about an axis 810 on a plate 62 which is carried by a stirrup 60, in the shape of a "U" returned, whose lateral branches are fixed, for example by welding, on the top of the bottom rail 6.

Les branches 61 présentent des orifices qui permettent le passage et le guidage des tiges de verrouillage 80 ; une lumière 600 prévue dans la branche horizontale supérieure de l'étrier 60 autorise le passage et le débattement de l'une des biellettes 811 et de la partie inférieure du levier 81.The branches 61 have orifices which allow the passage and the guide of the locking rods 80; a light 600 provided in the upper horizontal leg of the stirrup 60 allows the passage and the movement of one of the links 811 and the lower part of the lever 81.

Le pivotement latéral du levier de commande 81, autour de son axe d'articulation 810, assure le déplacement simultané des deux tiges 80 vers l'extérieur (pour le verrouillage) ou vers l'intérieur (pour le déverrouillage), selon le sens de ce pivotement.The lateral pivoting of the control lever 81, around its hinge axis 810, ensures the simultaneous movement of the two rods 80 outwards (for locking) or inwards (for unlocking), in the direction of this pivoting.

Par ailleurs, à la base de chacune des plaques intérieures 4 du jeu de flasques 3-4, est monté un organe d'appui 9 ; celui-ci affecte la forme d'un rouleau d'axe transversal horizontal (parallèle à Y-Y') porté par un petit levier 90 articulé autour d'un axe 900 à la base de la plaque 4.Furthermore, at the base of each of the inner plates 4 of the flange set 3-4 is mounted a support member 9; it affects the shape of a transverse horizontal axis roller (parallel to Y-Y ') carried by a small lever 90 hinged about an axis 900 at the base of the plate 4.

Le rouleau 9 s'étend entre ce levier 900 de forme arquée, et un élément d'appui 91, également de forme arquée.The roller 9 extends between this lever 900 of arcuate shape, and a bearing element 91, also of arcuate shape.

En faisant pivoter le rouleau 9 autour de l'axe 900, on peut l'amener soit dans une position basse, dans laquelle les éléments 90 et 91 sont en appui contre la traverse 6, soit dans une position relevée désignée 9' (position escamotée illustrée en traits interrompus sur la droite de la figure 2).By rotating the roller 9 about the axis 900, it can be brought to a low position, in which the elements 90 and 91 are in abutment against the crossbar 6, or in a raised position designated 9 '(retracted position shown in broken lines on the right of the figure 2 ).

Les plaques 4 présentent une large échancrure centrale 40, dirigée vers l'avant (vers l'outil à recevoir) qui autorise le débattement de l'organe 9 dans son mouvement de pivotement.The plates 4 have a large central notch 40, directed forward (towards the tool to receive) which allows the movement of the member 9 in its pivoting movement.

Des moyens d'indexage et de blocage appropriés, non représentés, sont prévus pour assurer le maintien des organes d'appui 9 dans leur position haute escamotée.Suitable indexing and locking means, not shown, are provided to maintain the support members 9 in their retracted high position.

Des moyens similaires peuvent être prévus pour assurer le maintien des leviers 7 dans leur position basse escamotée, entre les paires de flasques 3 et 4.Similar means may be provided to maintain the levers 7 in their retracted low position between the pairs of flanges 3 and 4.

On notera sur la figure 2 l'existence de manchons 800, représentés en traits interrompus. Leur fonction et leur liaison avec le dispositif de verrouillage seront décrites plus loin, en référence notamment aux figures 15 à 18.We will note on the figure 2 the existence of sleeves 800, shown in broken lines. Their function and their connection with the locking device will be described later, with particular reference to Figures 15 to 18 .

En effet, ce dispositif n'a pas été représenté sur la figure 2 afin de ne pas l'alourdir exagérément.Indeed, this device was not represented on the figure 2 so as not to weigh it down too much.

En nous référant maintenant aux figures 3 à 5 nous allons décrire les organes d'accouplement d'un outil avec ce cadre porte-outil.Referring now to Figures 3 to 5 we will describe the coupling elements of a tool with this tool holder frame.

La figure 3 représente la face dorsale d'un outil appartenant à un premier standard, du type commercialisé par la société MAILLEUX.The figure 3 represents the dorsal surface of a tool belonging to a first standard, of the type marketed by MAILLEUX.

Dans l'exemple illustré, il s'agit d'une benne ; il est bien entendu que des outils autres que des bennes, conformes à ce premier standard portent des moyens d'accouplement identiques à ceux de cette benne.In the illustrated example, it is a bucket; it is understood that tools other than buckets, in accordance with this first standard carry coupling means identical to those of this bucket.

Les éléments d'accouplement de cet outil sur le cadre porte-outil comprennent essentiellement une paire de ferrures verticales 20a qui courent de la partie supérieure à la partie inférieure de la face dorsale de la benne, à laquelle elles sont soudées, ainsi qu'une paire de pattes 20'A, situées chacune en vis-à-vis de la partie haute de chaque ferrure, à une certaine distance de celle-ci, vers l'extérieur.The coupling elements of this tool on the tool holder frame essentially comprise a pair of vertical fittings 20a which run from the upper part to the lower part of the dorsal face of the body, to which they are welded, as well as a pair of legs 20'A, each located vis-à-vis the upper part of each fitting, at a distance from it, outwardly.

Entre la partie supérieure de chaque ferrure 20A et la patte 20'A associée est fixé un barreau 21 A d'axe horizontal et transversal.Between the upper part of each fitting 20A and the associated tab 20'A is fixed a bar 21 A of horizontal and transverse axis.

Les deux barreaux 21A équipant l'outil sont situés symétriquement de part et d'autre d'un axe vertical longitudinal médian et sont disposés coaxialement, c'est-à-dire dans le prolongement l'un de l'autre.The two bars 21A equipping the tool are located symmetrically on either side of a longitudinal central vertical axis and are arranged coaxially, that is to say in the extension of one another.

Dans leur partie basse, les ferrures 20A présentent un orifice de verrouillage 22A et une encoche 23A.In their lower part, the fittings 20A have a locking orifice 22A and a notch 23A.

Les orifices 22A sont Ă©galement coaxiaux, de mĂŞme que les encoches.The orifices 22A are also coaxial, as are the notches.

L'outil de la figure 4, qui est conforme à un deuxième standard, en l'occurrence le standard allemand désigné "DGS" est également une benne 2B, dont la face dorsale est pourvue d'une paire de ferrures 20B de type voisin de celles de l'outil précédemment décrit 2A.The tool of figure 4 , which conforms to a second standard, in this case the German standard designated "DGS" is also a body 2B, whose back face is provided with a pair of fittings 20B similar to those of the previously described tool 2A.

Toutefois, les ferrures 20B sont légèrement plus rapprochées l'une de l'autre que les ferrures 20A. Du côté extérieur, au niveau de la partie haute de chaque ferrure, est fixé un crochet 21B dont la partie active a la forme générale d'un bec en"U" retourné, formant une cavité semi-cylindrique.However, the fittings 20B are slightly closer to each other than the fittings 20A. On the outer side, at the upper part of each fitting, is fixed a hook 21B whose active part has the general shape of a beak "U" returned, forming a semi-cylindrical cavity.

Comme pour l'outil 2A, les ferrures 20B présentent en partie inférieure un orifice de verrouillage 22 B.As for the tool 2A, the fittings 20B have in the lower part a locking hole 22 B.

Au lieu d'une encoche, ces ferrures présentent un chant plat 23B qui fait office de surface d'appui contre le porte-outil, comme on le verra plus loin.Instead of a notch, these fittings have a flat edge 23B which acts as a bearing surface against the tool holder, as will be seen below.

L'outil 2C illustré à la figure 5 est une griffe. Il s'agit d'un outil conforme à un troisième standard en service sur le marché suédois, désigné "SMS".The 2C tool shown in figure 5 is a claw. It is a third standard compliant service tool on the Swedish market, designated "SMS".

Les ferrures prévues au dos de ces outils sont des tiges plates verticales 20C qui sont pourvues en partie haute d'un crochet 21C ayant la forme d'un bec dont l'ouverture, semi-cylindrique, est tournée vers le bas.The fittings provided on the back of these tools are vertical flat rods 20C which are provided in the upper part of a hook 21C having the shape of a spout whose opening, semi-cylindrical, is turned downwards.

A la base de chaque ferrure est prévu un oeillet semi-cylindrique 22C. Il présente une ouverture transversale faisant office d'orifice de verrouillage.At the base of each fitting is provided a semi-cylindrical eyelet 22C. It has a transverse opening acting as a locking orifice.

En référence à la figure 6, nous allons maintenant expliquer comment s'opèrent l'accrochage et la mise en place d'un outil conforme au premier standard sur le cadre porte-outil.With reference to the figure 6 , we will now explain how the hooking and the implementation of a tool complies with the first standard on the tool holder frame.

Il va de soi que, de manière connue, l'opérateur qui se trouve sur le tracteur agricole peut manipuler à sa guise le cadre porte-outil, en l'inclinant plus ou moins grâce au vérin de bennage et en le soulevant plus ou moins, grâce au vérin de levage, pour l'engager contre la face dorsale de l'outil, et pour accrocher l'outil.It goes without saying that, in a known manner, the operator on the agricultural tractor can manipulate the tool holder as he wishes, tilting it more or less with the tipping cylinder and lifting it more or less. , thanks to the lifting cylinder, to engage it against the dorsal surface of the tool, and to hook the tool.

Afin de pouvoir accoupler le cadre porte-outil à un outil conforme au premier standard, on relève les leviers 7 et on les immobilise dans leur position relevée, grâce aux tiges 52, comme cela a été expliqué plus haut.In order to be able to couple the tool frame to a tool according to the first standard, the levers 7 are raised and immobilized in their raised position, thanks to the rods 52, as explained above.

Les deux mains 700 se trouvent ainsi en position active.Both hands 700 are thus in the active position.

Par ailleurs, on abaisse les rouleaux d'appui 9 de telle sorte qu'ils se trouvent en butée contre la traverse 6.Furthermore, the support rollers 9 are lowered so that they abut against the crosspiece 6.

C'est cette configuration du cadre porte-outil qui est représenté sur la figure 6. La dimension transversale de chaque main 700 correspond, au jeu d'engagement près, à la longueur de chaque barreau 21 A, et leur écartement mutuel correspond également, bien entendu, à l'écartement mutuel de ces barreaux.It is this configuration of the tool holder frame which is represented on the figure 6 . The transverse dimension of each hand 700 corresponds to the game close engagement, the length of each bar 21 A, and their mutual spacing also corresponds, of course, to the mutual spacing of these bars.

De même, la largeur de la gouttière que constitue chaque main 700 correspond, au jeu d'emboîtement près, au diamètre d'un barreau 2 1 A.Likewise, the width of the gutter that constitutes each hand 700 corresponds, with the interlocking clearance, to the diameter of a bar 2 1 A.

En pratique, ce diamètre est égal à 50 mm.In practice, this diameter is equal to 50 mm.

La position des rouleaux 9 par rapport aux mains 700 lorsque ces rouleaux se trouvent dans leur position active de la figure 6, est déterminée de telle manière que lorsque les barreaux 21A sont engagés dans les mains 700, chaque rouleau vient en appui dans l'encoche 23A d'une ferrure.The position of the rollers 9 relative to the hands 700 when these rollers are in their active position of the figure 6 , is determined such that when the bars 21A are engaged in the hands 700, each roller bears in the notch 23A of a fitting.

De même, la position des tiges de verrouillage 80 est déterminée de telle sorte qu'après accrochage et mise en appui de l'outil 2A sur le porte-outil 1, les orifices de verrouillage 22A se trouvent chacun dans l'alignement axial Z-Z' desdites tiges 80.Similarly, the position of the locking rods 80 is determined such that after latching and pressing the tool 2A on the tool holder 1, the locking holes 22A are each in the axial alignment Z-Z ' said rods 80.

En référence à la figure 7, nous allons maintenant expliquer comment se fait l'accouplement du cadre porte-outil avec un outil 2B appartenant au second standard.With reference to the figure 7 , we will now explain how the coupling of the tool holder is done with a tool 2B belonging to the second standard.

On constate que les leviers 7 ont été escamotés, en position basse référencée 7'.It can be seen that the levers 7 have been retracted, in the low position referenced 7 '.

En revanche, les organes d'appui 9 ont été maintenus en position saillante active, comme dans la configuration précédente.On the other hand, the support members 9 have been kept in the active projecting position, as in the previous configuration.

Dans cette configuration, ce sont les tiges 52, faisant alors office d'organe d'accrochage, qui sont adaptées pour s'engager dans les crochets 21B, l'écartement mutuel des tiges 52 étant naturellement déterminé en conséquence.In this configuration, it is the rods 52, then acting hook member, which are adapted to engage in the hooks 21B, the spacing between the rods 52 being naturally determined accordingly.

Les tiges 52 ont un diamètre qui correspond, au jeu d'emboîtement près, à la largeur des ouvertures des crochets 21 B.The rods 52 have a diameter which corresponds to the interlocking clearance, to the width of the openings of the hooks 21 B.

En pratique, ce diamètre est de 40 mm.In practice, this diameter is 40 mm.

Comme dans le mode de fonctionnement précédent, les orifices 22B se positionnent en regard des tiges de verrouillage 80 et les chants d'appui 23B de l'outil viennent en appui contre les rouleaux 9.As in the previous operating mode, the orifices 22B are positioned opposite the locking rods 80 and the support edges 23B of the tool bear against the rollers 9.

En référence à la figure 8, nous allons maintenant expliquer quelle est la configuration du cadre porte-outil en vue de l'accouplement avec un outil 2C qui correspond au troisième standard.With reference to the figure 8 , we will now explain what is the configuration of the tool holder frame for the coupling with a tool 2C which corresponds to the third standard.

Comme précédemment, les leviers 7 sont escamotés (dans une position référencée 7') ; les rouleaux 9 sont également escamotés, par relevage, dans une position référencée 9'.As before, the levers 7 are retracted (in a position referenced 7 '); the rollers 9 are also retracted, by lifting, in a referenced position 9 '.

Dans cette configuration, ce sont les manchons 50, et plus particulièrement les portions de ces manchons qui se trouvent vers l'intérieur du cadre porte-outil par rapport aux plaquettes 51, qui font office de barreaux d'accrochage pour la paire de crochets 21C.In this configuration, it is the sleeves 50, and more particularly the portions of these sleeves which are towards the inside of the tool holder frame with respect to the plates 51, which serve as hooking bars for the pair of hooks 21C. .

L'écartement mutuel de ces portions de manchons correspond bien sûr à celui des deux crochets 21C ; de même, leur diamètre externe correspond à la largeur d'ouverture des crochets 21C.The mutual spacing of these sleeve portions corresponds of course to that of the two hooks 21C; likewise, their external diameter corresponds to the opening width of the hooks 21C.

En pratique, ce diamètre est de 60 mm.In practice, this diameter is 60 mm.

Les rouleaux d'appui 9 étant escamotés, la face dorsale de l'outil 2C vient en appui, par sa zone inférieure, directement contre la traverse 6. Dans cette position, les trous des oeillets 22C se positionnent dans l'axe Z-Z' des tiges de verrouillage 80.The support rollers 9 being retracted, the dorsal surface of the tool 2C abuts, by its lower zone, directly against the crosspiece 6. In this position, the holes of the eyelets 22C are positioned in the Z-Z ' axis . locking rods 80.

Les figures 9 à 14 illustrent également ces différentes configurations.The Figures 9 to 14 also illustrate these different configurations.

En référence aux figures 15 à 18, nous allons décrire les moyens de verrouillage de chacun de ces outils sur le cadre porte-outil.With reference to Figures 15 to 18 , we will describe the locking means of each of these tools on the tool holder frame.

Les orifices de verrouillage 22B et 22C ont un diamètre plus petit que les orifices de verrouillage 22A de l'outil 2A.The locking holes 22B and 22C have a smaller diameter than the locking holes 22A of the tool 2A.

Plus précisément, ces diamètres sont de 20 mm pour les outils 2B et 2C et de 30 mm pour l'outil 2A.More precisely, these diameters are 20 mm for tools 2B and 2C and 30 mm for tool 2A.

Les tiges de verrouillage 80 ont un diamètre adapté pour s'engager directement dans un orifice 22B ou 22C. Leur diamètre est donc légèrement inférieur à 20 mm.The locking rods 80 have a diameter adapted to engage directly in an orifice 22B or 22C. Their diameter is therefore slightly less than 20 mm.

Elles ne sont néanmoins pas adaptées pour pénétrer dans les orifices de verrouillage, dont le diamètre est nettement plus grand, d'un outil 1A.They are nevertheless not adapted to penetrate the locking holes, whose diameter is significantly larger, a tool 1A.

Grâce au dispositif illustré sur les figures 15 à 18, il est possible, malgré tout, d'assurer un verrouillage correct de chacun des trois types d'outils. Un système identique est associé à chacune des deux tiges 80.Thanks to the device illustrated on the Figures 15 to 18 , it is possible, in spite of everything, to ensure a correct locking of each of the three types of tools. An identical system is associated with each of the two rods 80.

La tige 80 est solidaire à son extrémité d'une barrette 83. Cette dernière est traversée par un alésage qui est engagé sur la portion d'extrémité de la tige 80, une goupille 830 assurant la solidarisation complète de la barrette 83 avec la tige 80.The rod 80 is integral at its end with a bar 83. The latter is traversed by a bore which is engaged on the end portion of the rod 80, a pin 830 ensuring the complete joining of the bar 83 with the rod 80 .

La barrette 83 s'Ă©tend perpendiculairement Ă  la tige 80, sensiblement dans un plan horizontal.The bar 83 extends perpendicular to the rod 80, substantially in a horizontal plane.

Le dispositif de verrouillage comprend également un levier articulé 87, qui peut pivoter en sa partie centrale autour d'un axe vertical 88.The locking device also comprises an articulated lever 87, which can pivot in its central part around a vertical axis 88.

Cet axe est porté par une plaque référencée 63 sur la figure 2.This axis is carried by a plate referenced 63 on the figure 2 .

A l'une de ses extrémités, ce levier 87 est solidaire d'un manchon 800. Une biellette 84 assure la liaison d'une extrémité de la barrette 83 avec l'autre extrémité du levier 87.At one of its ends, this lever 87 is integral with a sleeve 800. A connecting rod 84 connects one end of the bar 83 with the other end of the lever 87.

La biellette 84 est directement articulée, via un axe 86, sur le levier 87.The rod 84 is directly articulated, via an axis 86, on the lever 87.

Cette biellette présente une lumière 840 à l'intérieur de laquelle s'engage un doigt 85 solidaire de la barrette 83.This rod has a light 840 inside which engages a finger 85 integral with the bar 83.

Le manchon 800 a un diamètre d2 supérieur au diamètre d1 de la tige 80.The sleeve 800 has a diameter d 2 greater than the diameter d 1 of the rod 80.

Le manchon 800 est tubulaire ; il présente une ouverture centrale cylindrique 801 apte à s'engager, avec un certain jeu, sur la partie d'extrémité de la tige 80.The sleeve 800 is tubular; it has a cylindrical central opening 801 able to engage, with a certain clearance, on the end portion of the rod 80.

En observant les figures 15 et 16, on comprend que si la tige 80 est déplacée en translation axiale vers l'extérieur (vers la droite de la figure 15), comme cela est symbolisé par la flèche f, il en résulte un déplacement de la biellette 84 qui induit un pivotement du levier 87 autour de l'axe fixe 88, comme cela est symbolisé par la flèche g.By observing Figures 15 and 16 , it is understood that if the rod 80 is displaced in axial translation outwards (to the right of the figure 15 ), as is symbolized by the arrow f , it results in a displacement of the rod 84 which induces a pivoting of the lever 87 around the fixed axis 88, as is symbolized by the arrow g .

On a désigné par la référence t la trajectoire du centre du manchon 800 au cours de ce pivotement ; il s'agit d'une trajectoire en arc de cercle, tangente à l'axe de la tige 80.Reference t indicates the trajectory of the center of the sleeve 800 during this pivoting; it is a trajectory in an arc of a circle, tangent to the axis of the rod 80.

Ces mouvements sont rendus possible par la présence de la lumière 840 ; en fin de course, correspondant à la position de la figure 16, le manchon 800 se trouve engagé coaxialement sur la partie d'extrémité de la tige 80.These movements are made possible by the presence of light 840; at the end of the race, corresponding to the position of the figure 16 , the sleeve 800 is engaged coaxially on the end portion of the rod 80.

On notera que l'ouverture 801 intérieure au manchon 800 est bordée par une surface d'entrée conique 801', constituant une embouchure évasée qui autorise cet engagement en fin de course de pivotement du levier 87.It will be noted that the opening 801 inside the sleeve 800 is bordered by a conical inlet surface 801 'constituting a flared mouthpiece which allows this engagement at the end of the pivoting stroke of the lever 87.

Les diamètres d1 et d2 correspondent, au jeu d'engagement près, aux diamètres D1 et D2 correspondant, respectivement, aux diamètres des orifices de verrouillage des outils conformes au deuxième et au troisième standard, d'une part (20 mm), et au premier standard, d'autre part (30 mm).The diameters d 1 and d 2 correspond, with the engagement clearance, to the diameters D 1 and D 2 corresponding, respectively, to the diameters of the locking holes of the tools according to the second and third standards, on the one hand (20 mm ), and the first standard, on the other hand (30 mm).

L'écartement mutuel des orifices 22C est légèrement plus petit que l'écartement mutuel des orifices 22B, lequel est lui-même légèrement plus petit que l'écartement mutuel des orifices 22A.The mutual spacing of the orifices 22C is slightly smaller than the mutual spacing of the orifices 22B, which itself is slightly smaller than the mutual spacing of the orifices 22A.

Le dispositif de verrouillage est ainsi positionné et dimensionné que les ferrures 20B et 20C viennent se positionner en regard de la portion d'extrémité des tiges 80, entre la barrette 83 et le manchon 800 (figure 17).The locking device is thus positioned and dimensioned so that the fittings 20B and 20C are positioned facing the end portion of the rods 80, between the bar 83 and the sleeve 800 (FIGS. figure 17 ).

En revanche, la ferrure 20A, et corrélativement son orifice de verrouillage 22A, vient se positionner au niveau du manchon 800 (figure 18).In contrast, the fitting 20A, and correspondingly its locking orifice 22A, is positioned at the sleeve 800 ( figure 18 ).

On comprend donc que grâce à ce dispositif, on assure le verrouillage d'un outil conforme au premier standard par l'engagement du manchon 800 dans l'orifice 22A, comme cela est visible sur la figure 18 ; au contraire, pour un outil conforme au deuxième ou au troisième standard, le verrouillage est réalisé par la portion d'extrémité de la tige 80, comme cela est visible sur la figure 17.It is therefore understood that, thanks to this device, the locking of a tool conforming to the first standard is ensured by the engagement of the sleeve 800 in the orifice 22A, as can be seen in FIG. figure 18 ; on the contrary, for a tool conforming to the second or third standard, the locking is carried out by the end portion of the rod 80, as is visible on the figure 17 .

La mise en place de l'outil sur le cadre porte-outil se fait, bien sûr, alors que le dispositif est ouvert (figure 15), chaque ferrure 20 venant se placer entre l'extrémité d'une tige 80 et le manchon associé 800, après quoi on effectue le verrouillage (figure 17 ou 18).The implementation of the tool on the tool holder frame is, of course, while the device is open ( figure 15 ), each fitting 20 being placed between the end of a rod 80 and the associated sleeve 800, after which the locking is carried out ( figure 17 or 18 ).

Le déverrouillage s'opère par des mouvements en sens inverse.Unlocking occurs by movements in the opposite direction.

Sur les figures 19 à 21, on a hachuré les organes d'accouplement qui sont solidaires de l'outil, à des fins de meilleure lisibilité.On the Figures 19 to 21 the coupling members which are integral with the tool have been hatched, for purposes of better legibility.

La vue de la figure 19, qui se rapporte à un outil conforme au premier standard, montre que, d'une part, les barreaux 21A sont engagés dans les mains 700, et que les ferrures 20A se trouvent au niveau des manchons 800, lesquels en assurent le verrouillage.The view of the figure 19 , which refers to a tool according to the first standard, shows that, firstly, the bars 21A are engaged in the hands 700, and that the fittings 20A are at the sleeves 800, which ensure the locking.

On notera à l'observation de cette figure 19 que les pattes 20'A possèdent une portion oblique 200'A en forme de rampe, qui assure le bon guidage du cadre porte-outil par rapport à l'outil en début d'opération.Note the observation of this figure 19 that the tabs 20'A have a sloping portion 200'A ramp-shaped, which ensures the correct guidance of the tool holder frame relative to the tool at the beginning of operation.

Sur la vue de la figure 20, on constate que les ferrures 21B se trouvent en vis-à-vis des tiges 52, à l'extérieur des manchons 50 et des plaquettes 51 ; on observe également que les ferrures 20B se trouvent en regard des portions 80 des tiges de verrouillage (qui les traversent).On the view of the figure 20 it is found that the fittings 21B are opposite the rods 52, outside the sleeves 50 and the plates 51; it is also observed that the fittings 20B are opposite the portions 80 of the locking rods (which pass through them).

Dans ce mode de réalisation, ce sont les chants inclinés externes 510 des plaquettes 51 qui assurent le guidage et le centrage du cadre porte-outil par rapport à l'outil au cours de la phase d'approche, facilitant le bon positionnement des manchons 50 entre les crochets 21 B.In this embodiment, it is the external inclined edges 510 of the plates 51 which ensure the guiding and centering of the tool-holder frame relative to the tool during the approach phase, facilitating the proper positioning of the sleeves 50 between the brackets 21 B.

Sur la vue de la figure 21, on observe que les crochets 21C sont en prise avec les portions des manchons 50 situées vers l'intérieur par rapport aux plaquettes 51 ; ce sont les chants inclinés internes 511 des plaquettes 51 qui assurent le guidage et le centrage de l'outil par rapport au cadre porte-outil au cours de la phase d'approche, les crochets venant cette fois se placer à l'intérieur des deux plaquettes 51.On the view of the figure 21 it is observed that the hooks 21C are in engagement with the portions of the sleeves 50 situated inward with respect to the plates 51; it is the internal inclined edges 511 of the plates 51 which ensure the guiding and centering of the tool relative to the tool holder frame during the approach phase, the hooks this time being placed inside the two pads 51.

Comme dans le cas précédent, les orifices de verrouillage 22C se trouvent positionnés vis-à-vis des tiges 80, qui les traversent, dans une position légèrement décalée vers l'intérieur par rapport à la position occupée par les orifices 22B.As in the previous case, the locking holes 22C are positioned relative to the rods 80, which pass through them, in a position slightly inwardly offset with respect to the position occupied by the orifices 22B.
