Figure 2 : vue latérale du dispositif de la figure 1 ;
Figures 3,4 et 5 : vues de détail montrant le mécanisme de l'attache des figures 1 et 2 successivement en configuration déverrouillage (figure 3), configuration intermédiaire (figure 4) avec déplacement des axes d'un godet, et configuration verrouillage (figure 5). The invention will be better understood with the aid of the description below, of a nonlimiting embodiment, made with reference to the following appended figures:
Figure 1: overview of a quick coupling device according to the invention;
Figure 2: side view of the device of Figure 1;
Figures 3,4 and 5: detailed views showing the attachment mechanism of Figures 1 and 2 successively in unlocking configuration (Figure 3), intermediate configuration (Figure 4) with displacement of the axes of a bucket, and locking configuration ( figure 5).
L'attache rapide représentée sur les figures se compose d'un caisson 1 et d'un mécanisme de verrouillage. The quick coupler shown in the figures consists of a box 1 and a locking mechanism.
Le caisson 1 est formé de deux flasques latéraux 2 maintenus parallèles par plusieurs entre-axes, dont deux entre-axes supérieurs 3 et 4 servant également à la fixation du caisson au bout du bras ou de la flèche d'une pelle mécanique (non représentée), et un entre-axe inférieur 5, par exemple de même diamètre que les entre-axes supérieurs 3 et 4, et servant d'axe de rotation pour un ensemble de déverrouillage détaillé plus loin. Un quatrième entre-axe 6, de diamètre pouvant être inférieur à celui des précédents entre-axes, sert d'axe de rotation pour une gâchette détaillée plus loin. The box 1 is formed by two lateral flanges 2 held parallel by several center lines, including two upper center lines 3 and 4 also serving for fixing the box at the end of the arm or of the boom of a mechanical shovel (not shown ), and a lower center distance 5, for example of the same diameter as the upper center lines 3 and 4, and serving as the axis of rotation for an unlocking assembly detailed below. A fourth inter-axis 6, of diameter which may be less than that of the previous inter-axes, serves as an axis of rotation for a trigger detailed below.
Chaque flasque latéral 2 comporte deux lumières débouchantes 7 et 8, dont une première lumière 7 à axe horizontal 9 débouchant sur l'avant du caisson, et une deuxième lumière 8 débouchant en dessous du caisson, avec un segment à axe 10 incliné d'un angle et par rapport à l'horizontale et un prolongement 11 à axe horizontal. Each lateral flange 2 has two openings 7 and 8, including a first light 7 with a horizontal axis 9 opening onto the front of the box, and a second light 8 opening below the box, with a segment with an axis 10 inclined by a angle and relative to the horizontal and an extension 11 to the horizontal axis.
L'ensemble de verrouillage se compose de trois organes de verrouillage 12a, 12b, 12c parallèles et solidaires montés à pivotement sur l'entre axe inférieur 5 entre une position de déverrouillage visible en figure 3 et une The locking assembly consists of three parallel and integral locking members 12a, 12b, 12c pivotally mounted on the lower axis 5 between an unlocking position visible in Figure 3 and a
<Desc/Clms Page number 3><Desc / Clms Page number 3>
position de verrouillage visible en figure 5 vers laquelle il est automatiquement ramené par un deuxième ressort de pression 14. locking position visible in FIG. 5 to which it is automatically brought back by a second pressure spring 14.
Chaque organe de verrouillage comporte en extrémité une encoche 21 de forme et dimension appropriées pour pouvoir bloquer un des axes d'accrochage d'un godet dans le fond de la deuxième lumière 8 (figure 5). Cette encoche 21 forme en haut de verrou, une dent 18 prolongeant le verrou vers l'arrière du caisson. Each locking member has at its end a notch 21 of suitable shape and size to be able to block one of the attachment axes of a bucket in the bottom of the second lumen 8 (FIG. 5). This notch 21 forms at the top of the lock, a tooth 18 extending the lock towards the rear of the box.
Une gâchette 15 en forme de doigt est montée à pivotement sur le quatrième entre-axe 6 prévu en haut du caisson et entre les deux entre-axes supérieurs 3 et 4. A finger-shaped trigger 15 is pivotally mounted on the fourth inter-axis 6 provided at the top of the box and between the two upper inter-axes 3 and 4.
Cette gâchette est mobile dans un plan vertical, contre le flan interne de l'un des flasques 2, entre une position déverrouillage (figure 3) selon laquelle son extrémité 15a obture le fond de la deuxième lumière débouchante 8 et une position verrouillage (figure 5) selon laquelle son extrémité dégage ladite lumière 8. This trigger is movable in a vertical plane, against the internal blank of one of the flanges 2, between an unlocking position (FIG. 3) according to which its end 15a closes the bottom of the second through light 8 and a locking position (FIG. 5) ) according to which its end gives off said light 8.
Un premier ressort de pression 16 ramène automatiquement la gâchette en configuration déverrouillage (figure 3). Une encoche 17 est prévue vers l'avant de la gâchette et sert à l'accrochage de la dent 18 de l'un des organes de verrouillage 12a ou 12b ou 12c placé contre le même flasque que la gâchette. A first pressure spring 16 automatically returns the trigger to the unlocking configuration (FIG. 3). A notch 17 is provided towards the front of the trigger and is used for hooking the tooth 18 of one of the locking members 12a or 12b or 12c placed against the same flange as the trigger.
Lorsque la dent 18 est encliquetée dans l'encoche 17, l'ensemble de verrouillage est en configuration déverrouillage ; il est incliné avec la dent dirigée vers le haut du caisson et il libère totalement les deuxièmes lumières 8. When the tooth 18 is snapped into the notch 17, the locking assembly is in the unlocking configuration; it is inclined with the tooth directed towards the top of the box and it completely releases the second lights 8.
Lorsque le caisson se présente devant un godet ou tout autre outil à attacher, les deux axes d'accrochage 19 et 20 du godet sont présentés aux entrées des lumières 7 et 8, puis guidés dans les lumières selon leurs axes respectifs 9,10 et 11 (figure 4) jusqu'à arriver dans les fonds des dites lumières. Arrivé en bout de When the box is presented in front of a bucket or any other tool to be attached, the two attachment axes 19 and 20 of the bucket are presented at the entrances of the openings 7 and 8, then guided in the openings along their respective axes 9, 10 and 11 (Figure 4) until reaching the bottom of said lights. Arrived at the end of
<Desc/Clms Page number 4><Desc / Clms Page number 4>
course, l'axe arrière 20 du godet appuie sur l'extrémité 15a de la gâchette 15 qui recule et libère la dent 18 de l'ensemble de verrouillage qui bascule en position de verrouillage en bloquant le dit axe arrière 20 dans les fonds des lumières 8. stroke, the rear axis 20 of the bucket presses on the end 15a of the trigger 15 which moves back and releases the tooth 18 from the locking assembly which switches to the locking position by blocking said rear axis 20 in the bottoms of the lights 8.
Pour le déverrouillage du godet ou de l'outil, on peut prévoir des moyens à action manuelle, ou des moyens à action électrique. For unlocking the bucket or the tool, there may be means with manual action, or means with electric action.
Avantageusement, comme illustré notamment en figure 3, les axes respectifs des 9, 11 des lumières ou encoches 7,8 sont alignés dans le prolongement l'un de l'autre, et l'axe 5 servant à la rotation de l'ensemble de verrouillage est disposé sur la même ligne. Advantageously, as illustrated in particular in FIG. 3, the respective axes of the 9, 11 of the slots or notches 7, 8 are aligned in the extension of one another, and the axis 5 serving for the rotation of the assembly of lock is arranged on the same line.
Selon une première variante simple, l'organe central de verrouillage est équipé d'un levier de manoeuvre 13 déjà cité. Une pression en extrémité du levier soulève l'ensemble du verrouillage, libère le godet et encliquète la dent 18 dans l'encoche 17. According to a first simple variant, the central locking member is equipped with an operating lever 13 already mentioned. Pressing at the end of the lever lifts the locking assembly, releases the bucket and snaps the tooth 18 into the notch 17.
Les deux organes de verrouillage latéraux 12a et 12c sont placés contre les flancs intérieurs des flasques 2. L'organe de verrouillage central 12b pouvant être prolongé vers l'avant du caisson par un levier de manoeuvre 13. The two lateral locking members 12a and 12c are placed against the inner sides of the flanges 2. The central locking member 12b can be extended towards the front of the box by an operating lever 13.
Selon une deuxième variante non représentée, le déverrouillage est commandé électriquement par un système à solénoïde alimenté en courant depuis la cabine de la pelle mécanique. According to a second variant, not shown, the unlocking is electrically controlled by a solenoid system supplied with current from the cabin of the mechanical shovel.
Pour éviter les accidents, cette commande fonctionne avec une clé de contact. To avoid accidents, this command works with an ignition key.
En outre, la largeur du caisson est modifiable par remplacement des entre-axes par des entre-axes de la longueur recherchée. A cet effet, les entre-axes sont démontables et maintenus en place par des vis de pression 22. In addition, the width of the box can be modified by replacing the inter-axes with inter-axes of the desired length. For this purpose, the inter-axes are removable and held in place by pressure screws 22.
Il est également possible d'attacher un godet ou tout autre outil sur un caisson de largeur inférieure à la distance entre les oreilles du godet ; il suffit que les axes d'attache 19 et 20 du godet aient un diamètre inférieur à la largeur des lumières 7 et 8. It is also possible to attach a bucket or any other tool to a box of width less than the distance between the ears of the bucket; it is sufficient that the attachment pins 19 and 20 of the bucket have a diameter less than the width of the openings 7 and 8.

Enfin, une attache rapide selon l'invention est simple à construire et à utiliser, et sa fiabilité est totale car le godet ne peut se décrocher même s'il subit des chocs ou des vibrations pendant le travail. Finally, a quick coupler according to the invention is simple to build and use, and its reliability is total because the bucket cannot come off even if it is subjected to shocks or vibrations during work.
