Description

TITRE : Dispositif de sécurité pour attache rapide destinée à fixer un outil à l'extrémité du bras d'un chargeur ou analogue. TITLE: Safety device for quick coupler intended to fix a tool at the end of the arm of a loader or the like.
La présente invention est relative à un dispositif de sécurité pour attache rapide destinée à fixer un outil à l'extrémité du bras d'un chargeur ou analogue.The present invention relates to a safety device for quick coupler intended to fix a tool at the end of the arm of a loader or the like.
L'état de la technique est constitué, entre autres, par l'attache décrite dans la demande de brevet français publiée sous le numéro 2785952.The state of the art consists, among other things, of the fastener described in the French patent application published under the number 2785952.
Dans ce document, il est décrit une attache en deux parties, comportant un organe d'accrochage pourvu d'un berceau permettant d'enfourcher un arbre rendu solidaire de l'autre partie, l'une des parties comportant une ouverture pouvant être traversée par une extension en forme de crochet sous laquelle peut s'insérer une plaque de verrouillage coulissante permettant de maintenir plaquée l'une contre l'autre les deux pièces constituant l'attache.In this document, there is described a fastener in two parts, comprising a hooking member provided with a cradle making it possible to straddle a shaft made integral with the other part, one of the parts comprising an opening that can be crossed by a hook-shaped extension under which a sliding locking plate can be inserted, making it possible to keep the two parts constituting the fastener pressed against one another.
La plaque de verrouillage est maintenue en position armée et, dans cette position, elle ne s'oppose pas au passage de l'extension en forme de crochet à travers l'ouverture précitée. C'est lors de ce passage que l'extension précitée libère la plaque de verrouillage qui, sous l'action de ressorts qui se détendent, s'insère sous le crochet pour verrouiller les deux parties de l'attache l'une contre l'autre.The locking plate is kept in the armed position and, in this position, it does not oppose the passage of the hook-shaped extension through the aforementioned opening. It is during this passage that the aforementioned extension releases the locking plate which, under the action of springs which relax, is inserted under the hook to lock the two parts of the fastener one against the other.
Le crochet et la plaque présentent des surfaces obliques qui coopèrent et plaquent les deux parties de l'attache l'une contre l'autre. Si, pour une raison quelconque, présence de terre par exemple, la plaque de verrouillage ne s'étend qu'imparfaitement sous la partie correspondante du crochet, la coopération précitée est imparfaite et sous les chocs et les vibrations, un risque de décrochage est à craindre avec tous les inconvénients que cela peut présenter.The hook and the plate have oblique surfaces which cooperate and press the two parts of the fastener one against the other. If, for any reason, presence of earth for example, the locking plate extends only imperfectly under the corresponding part of the hook, the abovementioned cooperation is imperfect and under shock and vibration, there is a risk of stalling fear with all the inconvenience this may present.
La présente invention, qui remédie à cet inconvénient, est remarquable en ce que le crochet présente un moyen susceptible de coopérer avec la plaque de verrouillage pour s'opposer à la rotation de la partie de l'attache comportant ledit crochet.The present invention, which overcomes this drawback, is remarkable in that the hook has a means capable of cooperating with the locking plate to oppose the rotation of the part of the fastener comprising said hook.
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 :The present invention will be better understood from the following description made with reference to the accompanying drawings by way of indicative example only, in which:
-la figure 1 est une vue d'une attache rapide d'un type connu;FIG. 1 is a view of a quick coupler of a known type;
-la figure 2 est une vue, à plus grande échelle de la figure 1 , montrant la position de la plaque de verrouillage lorsqu'un incident se produit;FIG. 2 is a view, on a larger scale of FIG. 1, showing the position of the locking plate when an incident occurs;
-la figure 3 est une vue, analogue à celle 1 , montrant une attache modifiée selon l'invention;FIG. 3 is a view, similar to that 1, showing a modified fastener according to the invention;
-la figure 4 est la vue de dessus de la figure 3;FIG. 4 is the top view of FIG. 3;
-la figure 5 est une vue, analogue à celle 4, montrant l'attache en position de sécurité;FIG. 5 is a view, similar to that 4, showing the fastener in the safety position;
-la figure 6 est la vue en élévation de la figure 5FIG. 6 is the elevation view of FIG. 5
En se reportant à la figure 1 , on voit que l'attache, qui est conforme à celle décrite dans la demande de brevet français publiée sous le numéro 2785952, comporte deux parties 1 et 2, affectant chacune sensiblement la forme d'un étrier. L'une des parties comporte un arbre 3 pouvant être saisi par un berceau 4 de l'autre partie.Referring to Figure 1, we see that the fastener, which conforms to that described in the French patent application published under the number 2785952, has two parts 1 and 2, each substantially affecting the shape of a stirrup. One of the parts has a shaft 3 which can be gripped by a cradle 4 of the other part.
La pièce 2 présente sur sa partie médiane 2a une extension 5 formantThe part 2 has on its middle part 2a an extension 5 forming
I un crochet 6. L'extension 5 peut traverser une ouverture 7 prévue sur la partie médiane 1 a de la partie 1.I a hook 6. The extension 5 can pass through an opening 7 provided on the middle part 1 a of part 1.
Sur îa partie 1 peut coulisser une plaque de verrouillage 8, présentant une ouverture 9 de passage de l'extension 5.On the part 1 can slide a locking plate 8, having an opening 9 for passage of the extension 5.
Sur la figure 1 , la plaque 8 est représentée en position armée, les ouvertures 7 et 9 étant sensiblement en coïncidence. La plaque 8 est maintenue dans cette position au moyen, par exemple d'un doigt de verrouillage pivotant 10.In Figure 1, the plate 8 is shown in the armed position, the openings 7 and 9 being substantially coincident. The plate 8 is held in this position by means, for example of a pivoting locking finger 10.
Lors de la rotation, autour de l'axe de l'arbre 3, l'extension 5 repousse le doigt 10 et la plaque , sous l'effet des ressorts de rappel usuels, se déplace selon la flèche Fi .During rotation, around the axis of the shaft 3, the extension 5 pushes the finger 10 and the plate, under the effect of the usual return springs, moves according to the arrow Fi.
Si rien ne s'oppose au déplacement, présence de terre par exemple, le bord oblique 8a de la plaque 8 vient s'insérer sous la partie 6a du crochet, la coopération des parties obliques en contact ayant pour effet de plaquer des deux parties de l'attache l'une contre l'autre.If nothing prevents the movement, presence of earth for example, the oblique edge 8a of the plate 8 is inserted under the part 6a of the hook, the cooperation of the oblique parts in contact having the effect of pressing two parts of tie it together.
Si les surfaces devant coopérer sont plus ou moins noyées dans de la terre, la plaque 8 sous l'action des ressorts, qui sont alors fortement bandés, va se déplacer selon la flèche F1 mais ne s'insérer qu'imparfaitement sous le crochet en donnant l'illusion d'un verrouillage qui, en fait, ne s'est pas effectué. C'est ce type d'incident qui est représenté sur la figure 2. Sur cette figure, on constate que les surfaces 8a et 6a ne sont pas appliquées l'une contre-, l'autre. De ce fait, lors du travail, les chocs et les vibrations peuvent entraîner le décrochage et la chute de l'outil relié au bras de l'engin.If the surfaces to cooperate are more or less embedded in the earth, the plate 8 under the action of the springs, which are then strongly bandaged, will move according to the arrow F1 but only be inserted imperfectly under the hook in giving the illusion of a locking which, in fact, did not happen. This type of incident is shown in Figure 2. In this figure, it can be seen that the surfaces 8a and 6a are not applied one against the other. Therefore, during work, shocks and vibrations can cause the tool connected to the arm of the machine to fall off and fall.
La présente invention, qui remédie à cet inconvénient, consiste à prévoir un dispositif de sécurité s'opposant au pivotement de la partie comportant le crochet dès que celui-ci a traversé les ouvertures 7 et 9.The present invention, which overcomes this drawback, consists in providing a safety device opposing the pivoting of the part comprising the hook as soon as the latter has passed through the openings 7 and 9.
Selon un mode de réalisation, l'extension 5 présente à sa partie supérieure, au moins, un doigt latéral 11 , les ouvertures 7 et 9 présentant des décrochements 12 et 13 permettant le passage dudit doigt.According to one embodiment, the extension 5 has at its upper part, at least, a lateral finger 11, the openings 7 and 9 having recesses 12 and 13 allowing the passage of said finger.
Lorsque la plaque 8 est en position armée, les ressorts de rappel usuels 14 étant bandés, les décrochements 12 et 13 sont en coïncidence (fig.3 et 4) .When the plate 8 is in the armed position, the usual return springs 14 being bandaged, the recesses 12 and 13 are in coincidence (fig. 3 and 4).
A la fin du mouvement, pour passer de la position représentée sur la figure 4 à celle représentée sur la figure 6, l'extension 5 repousse le doigt 10 et les doigts 11 se trouvent situés au-dessus du plan de la plaque 8, qui se déplace selon la flèche Fi.At the end of the movement, in order to pass from the position shown in FIG. 4 to that shown in FIG. 6, the extension 5 repels the finger 10 and the fingers 11 are located above the plane of the plate 8, which moves according to the arrow Fi.
Sur la figure 6 est montré le même type d'incident que celui représenté sur la figure 2 : le contact entre les surfaces 6a et 8a est très imparfait de la terre empêchant, par exemple, à la plaque 8 de s'insérer complètement sous le crochet. Si le contact entre les deux surfaces précitées est rompu, la partie 2 de l'attache va pivoter, légèrement jusqu'au moment où les doigts 11 vont venir prendre appui contre la plaque 8 en s'opposant au décrochage et à la chute de l'outil relié à ladite partie 2. In FIG. 6 is shown the same type of incident as that represented in FIG. 2: the contact between the surfaces 6a and 8a is very imperfect from the ground preventing, for example, the plate 8 from fitting completely under the hook. If the contact between the two aforementioned surfaces is broken, part 2 of the fastener will pivot, slightly until the fingers 11 will come to bear against the plate 8 by opposing the stall and the fall of the tool linked to said part 2.
