Definitions
- the present invention relates to improvements to quick fasteners for attaching a tool, such as a bucket, to the end of the arm of a charger.
- a quick coupler has two parts distinct, one of which is made integral with the arm and will be called while the other, who can cooperate with the first, results of a modification of the tool or is constituted by a piece made joint of the tool and will be referred to hereinafter as "adapter".
- one of the parties has a cradle in the shape of a hook likely to grab a tree carried by the other party, both said parts being applied against each other by a judicious rotation of one of them around the axis of the aforementioned tree. In most of the cases this rotation triggers the implementation of a locking device automatic.
- a locking device is described, in particular, in the European patent No. 438931 or in the French patent application No. 2785952 of 12 October 1999.
- the adapter is in the form of a caliper against the fields of the wings which the fastening member is supported at the end of its rotation.
- the contacts are carried out according to two oblique surfaces arranged in vee.
- This device does not give complete satisfaction. Indeed, as he is used in a messy environment, consisting of earth, clay and pebbles forming a conglomerate likely to adhere to the metal parts, we have found that, before locking the tool, it was necessary to ensure the cleanliness the device and remove any impurities that may be in between surfaces to be contacted. Indeed, if the contact is not total lock is made impossible.
- the contacts between the two pieces of the quick coupler take place at points that are distant from the common axis of pivoting of the two said parts.
- the quick coupler comprises two parts 1 and 2.
- part 1 which constitutes the attachment member, is articulated by a shaft 3 to the end of the arm 4 of a digger and it can rotate around the axis of this tree.
- Part 2, or adapter is made integral, a bucket 5, for example.
- part 2 has an extension 6, fit hook, able to pass through an orifice of the middle part 7 of the piece 1 to unlock a locking plate 8 which, under the action of springs 9 (see fig.7), fits under the shoulder 6a of the hook 6.
- Part 1 has, at least, a support extension 10 of a tree 11 1 extending from both sides of said extension.
- Part 2 presents two hooks 12 leaving between them sufficient space to allow the passage of the extension 10. It should be noted that, when the tool 5 rests on the ground, the hooks 12 open down which prevents the earth stagnates in the recesses of said hooks.
- the contact between the two parts 1 and 2 is carried out according to a length L (fig.2) which is very important and if the earth adheres to one or other of the surfaces to come into contact in an area near the shaft 11, the locking between the parts 1 and 2 will be impossible.
- the piece 1 has, for a length at least equal to the length L, oblique bearing surfaces 14, the angle A which, in FIG. 9, is the one formed by each oblique scope and the horizontal, being equal to that B which, in FIG. is that formed by the surface 13 and the horizontal.
- Each surface 13 is extended by a surface 15 which forms with horizontal (fig.6) an angle C greater than that B.
- impurities are present on one or other of the surfaces 15 or 14, these can be housed in the space 16 remaining between the two pieces 1 and 2 and extending over the most of the length of the room 2.
- this disadvantage is remedied by providing means that precludes any relative displacement between square brackets 12 and the shaft 11 when the two parts are locked on one another.
- the piece 1 presents, at the right of the tree 11, a concave stop 17 formed by a cylindrical surface to director circle centered on the axis of the shaft 11.
- One of the hooks 12 at least, has an outer portion 12a constituted by a cylindrical surface with circular director who, in the case of Figure 2, is centered on the axis of the shaft 11 and whose radius is, with the functional game close, equal to that of the direction of the surface forming the abutment 17.
- the portion 12a is connected, without solution of continuity, with a portion 12b whose distance to the aforementioned axis decreases to its end 12c.
- the means described so far have the effect of opposing the appearance of games that could lead to a displacement of parts 1 and 2 in a vertical plane. Since the bearing surfaces 13 are reduced, it is important to provide means to compensate for the lack of lateral guidance.

Abstract
Description
La présente invention est relative à des perfectionnements aux attaches rapides pour fixer un outil, tel qu'un godet, à l'extrémité du bras d'un chargeur.The present invention relates to improvements to quick fasteners for attaching a tool, such as a bucket, to the end of the arm of a charger.
De la façon connue, une attache rapide comporte deux parties distinctes, dont l'une est rendue solidaire du bras et sera dénommée organe d'accrochage, tandis que l'autre, qui peut coopérer avec la première, résulte d'une modification de l'outil ou est constituée par une pièce rendue solidaire de l'outil et sera dénommée ci-après "adaptateur".In known manner, a quick coupler has two parts distinct, one of which is made integral with the arm and will be called while the other, who can cooperate with the first, results of a modification of the tool or is constituted by a piece made joint of the tool and will be referred to hereinafter as "adapter".
Plus précisément, l'une des parties comporte un berceau en forme de crochet susceptible de saisir un arbre porté par l'autre partie, les deux dites parties étant appliquées l'une contre l'autre par une rotation judicieuse de l'une d'entre elles autour de l'axe de l'arbre précité. Dans la plupart des cas cette rotation déclenche la mise en oeuvre d'un dispositif de verrouillage automatique. Un tel dispositif est décrit, notamment, dans le brevet européen N° 438931 ou dans la demande de brevet français N°2785952 du 12 octobre 1999.More specifically, one of the parties has a cradle in the shape of a hook likely to grab a tree carried by the other party, both said parts being applied against each other by a judicious rotation of one of them around the axis of the aforementioned tree. In most of the cases this rotation triggers the implementation of a locking device automatic. Such a device is described, in particular, in the European patent No. 438931 or in the French patent application No. 2785952 of 12 October 1999.
Dans le dispositif décrit dans la demande de brevet français précitée, l'adaptateur se présente sous la forme d'un étrier contre les champs des ailes duquel l'organe d'accrochage prend appui à la fin de sa rotation. Pour s'opposer à la création de jeux entre les deux pièces, les contacts s'effectuent selon deux surfaces obliques disposées en vé. In the device described in the aforementioned French patent application, the adapter is in the form of a caliper against the fields of the wings which the fastening member is supported at the end of its rotation. For oppose the creation of games between the two pieces, the contacts are carried out according to two oblique surfaces arranged in vee.
Ce dispositif ne donne pas entière satisfaction. En effet, comme il est utilisé dans un milieu salissant, composé de terre, de glaise et de cailloux formant un conglomérat susceptible d'adhérer aux parties métalliques, on a constaté qu'il fallait, avant le verrouillage de l'outil, s'assurer de la propreté du dispositif et éliminer toutes les impuretés susceptibles de se trouver entre des surfaces devant être mises en contact. En effet, si le contact n'est pas total le verrouillage est rendu impossible.This device does not give complete satisfaction. Indeed, as he is used in a messy environment, consisting of earth, clay and pebbles forming a conglomerate likely to adhere to the metal parts, we have found that, before locking the tool, it was necessary to ensure the cleanliness the device and remove any impurities that may be in between surfaces to be contacted. Indeed, if the contact is not total lock is made impossible.
Selon l'invention, qui remédie à cet inconvénient, les contacts entre les deux pièces de l'attache rapide ont lieu en des points qui sont éloignés de l'axe commun de pivotement des deux dites pièces.According to the invention, which overcomes this drawback, the contacts between the two pieces of the quick coupler take place at points that are distant from the common axis of pivoting of the two said parts.
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 élévation d'une attache rapide conforme à l'invention appliquée à la fixation d'un godet à l'extrémité du bras d'un chargeur;
- la figure 2 est une vue, analogue à la figure 1, montrant une phase ultérieure de l'accrochage;
- la figure 3 est une vue à plus grande échelle et limitée à l'attache montrant celle-ci en position de verrouillage de l'outil;
- la figure 4 est une vue en coupe verticale de l'adaptateur;
- la figure 5 est la vue de gauche de la figure 4;
- la figure 6 est une vue en coupe effectuée selon la ligne VI-VI de la figure 4;
- la figure 7 est une vue en élévation de l'organe d'accrochage;
- la figure 8 est la vue de gauche de la figure 7;
- la figure 9 est une vue en coupe effectuée selon la ligne IX-IX de la figure 7.
- les figures 10 et 11 sont des vues en coupe effectuées respectivement selon les lignes X-X et XI-XI de la figure 3, les vues en coupe étant redressées.
- Figure 1 is an elevational view of a quick coupler according to the invention applied to the attachment of a bucket at the end of the arm of a loader;
- Figure 2 is a view similar to Figure 1 showing a subsequent phase of the attachment;

- Figure 7 is an elevational view of the latching member;
- Figure 8 is the left view of Figure 7;
- FIG. 9 is a sectional view along the line IX-IX of FIG. 7.
- Figures 10 and 11 are sectional views taken respectively along the lines XX and XI-XI of Figure 3, the sectional views being rectified.
Da la façon connue, l'attache rapide comporte deux parties 1 et 2. La
partie 1, qui constitue l'organe d'accrochage, est articulée, par un arbre 3 à
l'extrémité du bras 4 d'une pelle mécanique et elle peut pivoter autour de
l'axe de cet arbre. La partie 2, ou adaptateur, est rendue solidaire, d'un godet
5, par exemple.In the known manner, the quick coupler comprises two
D'une façon générale, les moyens utilisés pour verrouiller la partie 1 sur
celle 2 sont identiques à ceux décrits dans la demande de brevet français
N°2785952. Cela signifie que la partie 2 présente une extension 6, en forme
de crochet, susceptible de traverser un orifice de la partie médiane 7 de la
pièce 1 pour déverrouiller une plaque de verrouillage 8 qui, sous l'action de
ressorts 9 (voir fig.7), s'insère sous l'épaulement 6a du crochet 6.In general, the means used to lock
La partie 1 présente, au moins, une extension 10 de support d'un arbre
11 1 s'étendant de part et d'autre de ladite extension. La partie 2 présente
deux crochets 12 ménageant entre eux un espace suffisant pour permettre le
passage de l'extension 10. Il est à noter que, lorsque l'outil 5 repose sur le
sol, les crochets 12 s'ouvrent vers le bas ce qui évite que de la terre stagne
dans les creux desdits crochets.
Par une manoeuvre judicieuse du bras 4 on engage l'extension 10 entre
les crochets 12, puis on soulève le godet (fig.2) tout en faisant pivoter la
pièce 1 autour de l'axe de l'arbre 11 pour amener cette dernière dans la
position représentée sur la figure 3, qui correspond à celle de verrouillage du
godet, la pièce 1 étant appliquée contre celle 2. By a judicious maneuvering of the
Durant la rotation précitée, il est nécessaire que rien ne s'oppose au
contact entre les deux pièces 1 et 2 car, autrement, la plaque de verrouillage
ne peut pas s'insérer sous la partie 6a du crochet 6.During the aforementioned rotation, it is necessary that nothing precludes
contact between the two
Dans les dispositif connus, le contact entre les deux pièces 1 et 2
s'effectue selon une longueur L (fig.2) qui est très importante et si de la
terre adhère à l'une ou l'autre des surfaces devant entrer en contact dans
une zone située près de l'arbre 11, le verrouillage entre les pièces 1 et 2 sera
impossible.In the known devices, the contact between the two
Selon l'invention, le contact entre les pièces 1 et 2, bien que
s'effectuant de la façon connue selon deux surfaces disposées en Vé, a lieu
sur une portion très réduite 13 située à l'opposé des crochets 12.According to the invention, the contact between
La pièce 1 présente, sur une longueur au moins égale à la longueur L,
des portées obliques 14, l'angle A qui, sur la figure 9, est celui formé par
chaque portée oblique et l'horizontale, étant égal à celui B qui, sur la figure 6,
est celui formé par la surface 13 et l'horizontale.The
Chaque surface 13 se prolonge par une surface 15 qui forme avec
l'horizontale (fig.6) un angle C supérieur à celui B.Each
Il est à noter que les bords supérieurs des surfaces 13 et 15
correspondante sont dans le prolongement l'un de l'autre. De ce fait, et
comme cela ressort des figures 10 et 11, l'espace qui subsiste entre les
pièces 1 et 2 assemblées est obturé latéralement de façon à s'opposer à
l'introduction intempestive de terre et autres. It should be noted that the upper edges of
Comme cela ressort de la figure 11, si des impuretés sont présentes
sur l'une ou l'autre des surfaces 15 ou 14, celles-ci peuvent se loger dans
l'espace 16 subsistant entre les deux pièces 1 et 2 et s'étendant sur la
majeure partie de la longueur de la pièce 2.As shown in Figure 11, if impurities are present
on one or other of the
En réduisant l'importance des surfaces en contact on favorise, intempestivement, l'apparition de jeux destructeurs.By reducing the importance of the surfaces in contact we favor, inadvertently, the appearance of destructive games.
Selon l'invention, on remédie à cet inconvénient en prévoyant des
moyens qui s'oppose à tout déplacement relatif entre les crochets 12 et
l'arbre 11 lorsque les deux pièces sont verrouillées l'une sur l'autre.According to the invention, this disadvantage is remedied by providing
means that precludes any relative displacement between
Selon un mode de réalisation, la pièce 1 présente, au droit de l'arbre
11, une butée 17 concave formée par une surface cylindrique à directrice
circulaire centrée sur l'axe de l'arbre 11. L'un des crochets 12, au moins,
présente une portion extérieure 12a constituée par une surface cylindrique à
directrice circulaire qui, dans le cas de la figure 2, est centrée sur l'axe de
l'arbre 11 et dont le rayon est, au jeu fonctionnel près, égal à celui de la
directrice de la surface formant la butée 17. La portion 12a se raccorde, sans
solution de continuité, à une portion 12b dont la distance à l'axe précité
décroít jusqu'à son extrémité 12c.According to one embodiment, the
De cette façon et comme cela ressort de la figure 3, lorsque les pièces
1 et 2 sont verrouillées l'une sur l'autre, la portion 12a est disposée en
regard de la butée 17 et aucun déplacement n'est possible à ce niveau.In this way and as can be seen from Figure 3, when
1 and 2 are locked on one another, the portion 12a is arranged in
look at the
Les moyens décrits jusqu'à présent ont pour effet de s'opposer à
l'apparition de jeux pouvant entraíner un déplacement des pièces 1 et 2 dans
un plan vertical. Comme les surfaces d'appui 13 sont réduites, il importe de
prévoir des moyens pour compenser le manque de guidage latéral.The means described so far have the effect of opposing
the appearance of games that could lead to a displacement of
Selon l'invention et comme cela ressort de la figure 8 et 5, les faces
externes 18 de l'extension 10 et celles internes 19 des crochets 12 sont
fortement dépouillées étant fait observer que la distance d mesurée à la
naissance desdits crochets est égale, au jeu fonctionnel près, à la distance D
mesurée à la naissance de l'extension 10.According to the invention and as is apparent from FIGS. 8 and 5, the
De cette façon, on constate qu'un jeu important existe à l'instant où
l'arbre va pénétrer dans les crochets 12 et que ce jeu va diminuer durant la
rotation de la pièce 1 pour être nul lorsque les deux pièces 1 et 2 sont
verrouillées l'une sur l'autre.In this way, we see that an important game exists at the moment when
the tree will enter the
