Dans le dessin annexé
- la figure 1 représente une vue partielle en perspective et en éclaté d'un dispositif d'attache rapide selon l'invention.In the attached drawing
- Figure 1 shows a partial perspective and exploded view of a quick coupling device according to the invention.
- la figure 2 représente une vue partielle en plan du même dispositif. - Figure 2 shows a partial plan view of the same device.
Si on se réfère à ces figures on peut voir qu'un dispositif d'attache rapide selon l'invention comporte deux platines 1 et 2 de forme générale rectangulaire. If we refer to these figures we can see that a quick-release device according to the invention comprises two plates 1 and 2 of generally rectangular shape.
La platine 1 est disposée entre deux oreilles 3, dont une seule est représentée sur la figure 1, destinées à être solidarisées à l'extrémité d'un bras de manoeuvre, et entre lesquelles s'étend, à une extrémité, un axe pivot d'accrochage 30. The plate 1 is disposed between two ears 3, only one of which is shown in FIG. 1, intended to be secured to the end of an operating arm, and between which extends, at one end, a pivot axis d 'hanging 30.
La platine 2, destinée à être solidarisée à un godet ou analogue, comporte à l'une de ses extrémités un crochet 20 destiné à être ancré sur l'axe pivot 30 de manière à réunir les deux platines 1 et 2, à plat l'une contre l'autre. The plate 2, intended to be secured to a bucket or the like, has at one of its ends a hook 20 intended to be anchored on the pivot axis 30 so as to join the two plates 1 and 2, flat the one against the other.
La platine 2 comporte également, non loin de son extrémité opposée à celle comportant le crochet 20, deux plots 21 faisant saillie de la face 22 destinée à venir au contact de la platine 1, et présentant chacune latéralement une échancrure 23, tandis que la platine 1 comporte deux trous 10 dans chacun desquels s'insère l'un des plots 21 lorsque les deux platines 1 et 2 sont au contact l'une de l'autre. The plate 2 also comprises, not far from its end opposite to that comprising the hook 20, two studs 21 projecting from the face 22 intended to come into contact with the plate 1, and each having a laterally notch 23, while the plate 1 has two holes 10 in each of which is inserted one of the studs 21 when the two plates 1 and 2 are in contact with one another.
La platine 1 est munie dans la région médiane de sa face supérieure 11, opposée à celle destinée à venir au contact de la face 22 de la platine 2, deux glissières 12 parallèles, perpendiculaires à l'axe pivot 30, entre lesquelles est susceptible de se déplacer une clavette 4 en forme de plaque, sous l'action de deux vérins 13 solidaires de la platine 1 et disposés du côté de l'axe pivot 30. The plate 1 is provided in the middle region of its upper face 11, opposite to that intended to come into contact with the face 22 of the plate 2, two parallel slides 12, perpendicular to the pivot axis 30, between which is capable of move a key 4 in the form of a plate, under the action of two jacks 13 integral with the plate 1 and arranged on the side of the pivot axis 30.
La clavette 4 comporte, du côté opposé à celui en regard de l'axe pivot 30, un bord 40 destiné à être engagé dans les échancrures 23 des plots 21. The key 4 has, on the side opposite that opposite the pivot axis 30, an edge 40 intended to be engaged in the notches 23 of the studs 21.
Le bord 40 présente une partie médiane 41 étroite, bordée de deux pans 42 incliné par rapport à l'axe de déplacement de la clavette 4, les échancrures 23 étant de forme complémentaire, à savoir que le fond 24 de chacune d'elles est parallèle au pan 42 destiné à y être introduit. The edge 40 has a narrow middle portion 41, bordered by two sides 42 inclined relative to the axis of movement of the key 4, the notches 23 being of complementary shape, namely that the bottom 24 of each of them is parallel in pan 42 intended to be introduced there.
On peut voir également sur ces figures qu'un ressort 5 en forme de lame est placé longitudinalement contre la clavette 4, et solidarisé par une extrémité 50 à la platine 1 sensiblement entre les points de solidarisation à celle-ci des vérins 13. It can also be seen in these figures that a blade-shaped spring 5 is placed longitudinally against the key 4, and secured by one end 50 to the plate 1 substantially between the points of attachment to the latter of the jacks 13.
La clavette 4 comporte dans sa région médiane une lumière 43, tandis que le ressort 5 présente un ergot 51, non visible sur la figure 2, faisant saillie de sa face inférieure, qui prend appui sous l'effet élastique du ressort 5 contre la clavette 4, et susceptible de s'introduire dans la lumière 43 lorsque le bord 40 de la clavette 4 est introduit dans les échancrures 23 des plots 21. The key 4 has in its middle region a lumen 43, while the spring 5 has a lug 51, not visible in FIG. 2, protruding from its underside, which bears under the elastic effect of the spring 5 against the key 4, and capable of entering the lumen 43 when the edge 40 of the key 4 is introduced into the notches 23 of the studs 21.
On notera que le mécanisme est recouvert d'un carter, non représenté, permettant de le protéger, et qu'il comporte un système de lubrification, également non représenté, agissant notamment entre la clavette 4 et la platine 1. It will be noted that the mechanism is covered with a casing, not shown, making it possible to protect it, and that it comprises a lubrication system, also not shown, acting in particular between the key 4 and the plate 1.
Le fonctionnement du dispositif d'attache rapide selon l'invention est le suivant, de manière connue l'axe pivot 30 est crocheté par le crochet 20, et les platines 1 et 2 sont amenées l'une au contact de l'autre tandis que les plots 21 traversent la platine 1 par les trous 10. Sous l'action des vérins 13, la clavette 4 coulisse dans les glissières 12 en direction des plots 21, la partie 41 du bord 40 permettant le centrage de la clavette 4 entre les plots 21 dont les échancrures 23 accueillent les pans 42. Du fait du déplacement de la clavette 4, la lumière 43 se place en regard de l'ergot 51 qui, sous l'effet élastique du ressort 5, vient se loger dans la lumière 43 de manière à bloquer la clavette 4 dans la position de verrouillage. The operation of the quick coupling device according to the invention is as follows, in known manner the pivot axis 30 is hooked by the hook 20, and the plates 1 and 2 are brought into contact with each other while the studs 21 pass through the plate 1 through the holes 10. Under the action of the jacks 13, the key 4 slides in the slides 12 in the direction of the studs 21, the part 41 of the edge 40 allowing the key 4 to be centered between the studs 21, the notches 23 of which accommodate the flaps 42. Due to the displacement of the key 4, the light 43 is placed opposite the lug 51 which, under the elastic effect of the spring 5, is housed in the light 43 of so as to lock the key 4 in the locked position.
L'ouverture de l'attache rapide est réalisée en opérant de manière inverse, après avoir préalablement, afin de désengager l'ergot 51 de la lumière 43, soulevé le ressort 5 par son extrémité libre 52 au moyen d'un outil de forme adaptée permettant d'atteindre l'extrémité 52 en passant par une ouverture pratiquée dans le carter, non représenté. The opening of the quick coupler is carried out by operating in reverse, after having previously, in order to disengage the lug 51 from the light 43, lift the spring 5 by its free end 52 by means of a tool of suitable shape. to reach the end 52 through an opening in the housing, not shown.
I1 est à noter que dans ce mode de réalisation les vérins 13 sont pneumatiques, aussi, dans une variante, ceux-ci peuvent être remplacés par au moins un vérin hydraulique double effet, et dans ce cas, il n'est pas nécessaire d'équiper le dispositif d'un ressort 5 de verrouillage. I1 it should be noted that in this embodiment the jacks 13 are pneumatic, also, in a variant, these can be replaced by at least one double-acting hydraulic jack, and in this case, it is not necessary to equip the device with a locking spring 5.
I1 va de soi que la présente invention ne saurait être limitée à la description qui précède d'un de ses modes de réalisation, susceptible de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention. It goes without saying that the present invention cannot be limited to the preceding description of one of its embodiments, capable of undergoing a certain number of modifications without departing from the scope of the invention.
