La présente invention est relative à une attache rapide pour fixer un outil à l'extrémité du bras d'un chargeur ou analogue. The present invention relates to a quick coupler for fixing a tool to the end of the arm of a loader or the like.
D'une façon générale, une attache rapide comporte deux parties dont l'une est rendue solidaire du bras de l'engin et l'autre résulte d'une modification de l'outil ou est constituée par une pièce rendue solidaire dudit outil. In general, a quick coupler has two parts, one of which is made integral with the arm of the machine and the other resulting from a modification of the tool or is constituted by a part made integral with said tool.
L'une des parties comporte un arbre, situé vers l'une des extrémités de ladite partie, susceptible de coopérer avec un crochet, formant un palier ouvert, porté par l'autre pièce. One of the parts comprises a shaft, situated towards one of the ends of said part, capable of cooperating with a hook, forming an open bearing, carried by the other part.
Lorsque l'une des parties est accrochée sur l'autre, on fait pivoter l'ensemble de façon à les plaquer l'une sur l'autre ce qui entraîne le verrouillage automatique. Ce processus est bien connu et est décrit amplement dans la demande de brevet français publiée sous le numéro 2785951 ou dans la demande de brevet français NO 00 05606 du 3 mai 2000. When one of the parts is hooked on the other, the assembly is pivoted so as to press them one on the other which results in automatic locking. This process is well known and is fully described in the French patent application published under the number 2785951 or in the French patent application NO 00 05606 of May 3, 2000.
Dans la demande de brevet français N001 03205 du 9 mars 2001, on a exposé le problème selon lequel il importe que des moyens soient prévus pour maintenir, sans jeu, l'arbre appliqué contre le fond du ou des paliers formés par le ou les crochets. In French patent application N001 03205 of March 9, 2001, the problem was explained that it is important that means are provided to hold the shaft applied without play, against the bottom of the bearing or bearings formed by the hook (s) .
Dans la demande du 9 mars 2001, il est préconisé, pour atteindre le résultat précité, d'interposer entre les deux parties de l'attache un organe élastiquement déformable qui se trouve comprimé lorsque les deux pièces sont verrouillées et tend à les maintenir écartées. In the request of March 9, 2001, it is recommended, to achieve the aforementioned result, to interpose between the two parts of the fastener an elastically deformable member which is compressed when the two parts are locked and tends to keep them apart.

Ce dispositif donne toute satisfaction lorsqu'il est appliqué à la fixation de godets de petites dimensions, mais il n'en est plus de même lorsqu'il s'agit de godets de grandes dimensions car les efforts qui entrent en jeu sont incompatibles avec l'utilisation de silentblocs. This device gives full satisfaction when applied to the fixing of small-sized buckets, but it is no longer the same when it comes to large-sized buckets because the forces which come into play are incompatible with the use of silent blocks.
Selon la présente invention, l'une des parties de l'attache comporte un organe de coincement mobile susceptible à la fin du verrouillage des deux parties de s'insérer entre elles, le contact ayant lieu en un point situé sensiblement à l'aplomb de l'arbre. According to the present invention, one of the parts of the fastener comprises a movable wedging member capable, at the end of the locking of the two parts, of being inserted between them, the contact taking place at a point situated substantially in line with the tree.
La présente invention sera mieux comprise par la description qui va suivre faite en se référant aux dessins annexés à titre d'exemple indicatif, seulement, sur lesquels : -la figure 1 est une vue en coupe de la partie de l'attache, comportant l'arbre, modifiée selon l'invention ; -la figure 2 est la vue de dessus de la figure 1 ; -la figure 3 est une vue en coupe de la partie de l'attache comportant les crochets, modifiée selon l'invention ; -la figure 4 est la vue de dessus de la figure 3 ; -la figure 5 est une vue en coupe, à la fin du verrouillage et montrant l'action du dispositif de l'invention ; -la figure 6 est une vue en coupe, analogue à celle 5, montrant la position des organes mobiles permettant le décrochage. The present invention will be better understood from the description which follows made with reference to the accompanying drawings by way of indicative example only, in which: FIG. 1 is a sectional view of the part of the fastener, comprising: 'tree, modified according to the invention; FIG 2 is the top view of Figure 1; FIG. 3 is a sectional view of the part of the fastener comprising the hooks, modified according to the invention; FIG. 4 is the top view of FIG. 3; FIG. 5 is a sectional view, at the end of locking and showing the action of the device of the invention; FIG 6 is a sectional view, similar to that 5, showing the position of the movable members allowing the stall.
L'attache représentée a été limitée, pour ne pas compliquer inutilement les dessins, aux organes nécessaires à la compréhension du dispositif de l'invention. Il y a ainsi lieu de noter que tous les organes nécessaires pour fixer l'une ou l'autre des parties soit sur le godet soit au bras du chargeur ont été omises. The attachment shown has been limited, so as not to unnecessarily complicate the drawings, to the organs necessary for understanding the device of the invention. It should therefore be noted that all the components necessary to fix one or other of the parts either on the bucket or on the loader arm have been omitted.
<Desc/Clms Page number 3> <Desc / Clms Page number 3>
Ceci étant précisé, l'attache se compose de deux parties 1 et 2, celle 1 comportant l'arbre 3 et celle 2 les crochets 4. Having said this, the attachment consists of two parts 1 and 2, that 1 comprising the shaft 3 and that 2 the hooks 4.
Le verrouillage s'effectue par l'entremise d'un encliquetage automatique mettant en jeu une plaque coulissante 5 portée par la partie 1 et le cran 6 d'un sabot 7 porté par la partie 2. Ce mécanisme est décrit dans des documents antérieurs et, notamment, dans le document FR-2785952. The locking is effected by means of an automatic snap-in action involving a sliding plate 5 carried by the part 1 and the notch 6 of a shoe 7 carried by the part 2. This mechanism is described in prior documents and , in particular, in document FR-2785952.
Selon l'invention, la partie 2, comportant les crochets, présente une extension 8 s'étendant sensiblement à l'aplomb de l'emplacement de l'axe de l'arbre 3, ladite extension ménageant entre elle et la face correspondante 1 a de la partie 1, lorsque les deux parties sont verrouillées, un espace dans lequel on peut insérer un organe de coincement 9. According to the invention, the part 2, comprising the hooks, has an extension 8 extending substantially in line with the location of the axis of the shaft 3, said extension forming between it and the corresponding face 1 a of part 1, when the two parts are locked, a space in which a wedging member 9 can be inserted.
L'extension 8 présente une surface oblique 8a, formant rampe, susceptible de coopérer avec une surface ga, analogue, de l'organe 9 lorsque ce dernier se déplace selon la flèche FI. L'organe 9 est porté par une plaque 10, coulissante, maintenue contre la face 1 a de la partie 1. La plaque 10 est constamment soumise à une force tendant à la déplacer selon la flèche Fl. The extension 8 has an oblique surface 8a, forming a ramp, capable of cooperating with a similar surface ga of the member 9 when the latter moves along the arrow FI. The member 9 is carried by a sliding plate 10, held against the face 1a of the part 1. The plate 10 is constantly subjected to a force tending to move it according to the arrow F1.
Des ressorts, non représentés
Le maintien et le guidage de la plaque 10 sont assurés par des moyens connus, analogues à ceux utilisés pour le maintien et le guidage de la plaque de verrouillage 5. Dans le même esprit, la plaque 10 est soumise à l'action de
ressorts (non représentés) analogues à ceux, connus, utilisés pour la plaque 5. Springs, not shown
Maintaining and guiding the plate 10 is ensured by known means, similar to those used for maintaining and guiding the locking plate 5. In the same spirit, the plate 10 is subjected to the action of
springs (not shown) similar to those, known, used for the plate 5.
<Desc/Clms Page number 4> <Desc / Clms Page number 4>
Selon une autre caractéristique de l'invention, le recul de la plaque 5 est utilisé pour déterminer celui de la plaque 10, les deux plaques étant judicieusement dimensionnées de façon à ce que la course de la plaque 5 soit supérieure à celle de la plaque 10. According to another characteristic of the invention, the recoil of the plate 5 is used to determine that of the plate 10, the two plates being judiciously dimensioned so that the stroke of the plate 5 is greater than that of the plate 10 .
La plaque 10 présente, au moins un doigt 11 traversant l'orifice usuel 12 de passage du sabot 7 et celui 13 de la plaque de verrouillage. The plate 10 has at least one finger 11 passing through the usual orifice 12 for the passage of the shoe 7 and that 13 of the locking plate.
Si on considère la figure 5, on voit que l'organe 9 est inséré, à force, dans l'espace ménagé entre la rampe 8a et la face 1 a et tend à les écarter l'une de l'autre ce qui a pour effet de plaquer les paliers ouverts des crochets contre l'arbre 3. If we consider Figure 5, we see that the member 9 is inserted, by force, in the space formed between the ramp 8a and the face 1a and tends to separate them from each other which has for effect of pressing the open bearings of the hooks against the shaft 3.
Pour désaccoupler les deux parties de l'attache, on déplace la plaque 5, selon la flèche F2, de la façon usuelle. Le recul de la plaque 5 détermine celui de la plaque 10 par l'entremise des doigts 11 entraînés par le bord 13a de l'orifice 13. La partie 2 peut alors pivoter librement selon la flèche F3. To decouple the two parts of the fastener, the plate 5 is displaced, according to arrow F2, in the usual way. The recoil of the plate 5 determines that of the plate 10 by means of the fingers 11 entrained by the edge 13a of the orifice 13. The part 2 can then pivot freely according to the arrow F3.
