L'invention sera mieux comprise grâce à la description qui va suivre donnée à titre d'exemple non limitatif au regard des dessins annexés dans lesquels
La figure 1 représente une vue schématique d'un dispositif formant prise automatique d'outils de l'art antérieur avec indication de la position de verrouillage.The invention will be better understood thanks to the description which follows given by way of nonlimiting example with regard to the appended drawings in which
FIG. 1 represents a schematic view of a device forming an automatic grip for tools of the prior art with indication of the locking position.

La figure 2 représente une vue schématique d'un dispositif formant prise automatique d'outils de l'art antérieur dans le cas du non-verrouillage. FIG. 2 represents a schematic view of a device forming an automatic grip for tools of the prior art in the case of non-locking.

La figure 3 représente une vue schématique de dessus partielle du dispositif selon l'invention. FIG. 3 represents a partial schematic top view of the device according to the invention.

La figure 4 représente une vue schématique de côté dans le sens de la flèche IV de la figure 3, du dispositif selon 1 'invention.  Figure 4 shows a schematic side view in the direction of arrow IV of Figure 3, of the device 1 according to the invention.

La figure 5 représente une vue schématique du fonctionnement du dispositif selon l'invention. FIG. 5 represents a schematic view of the operation of the device according to the invention.

En référence à la figure 1, un ensemble 1 d'extrémité d'une machine de terrassement est muni d'un embout conique 2 et d'un orifice conique 3. With reference to FIG. 1, an end assembly 1 of an earthmoving machine is provided with a conical tip 2 and a conical orifice 3.

De préférence, conformément au brevet français 80 02095 dont le contenu est considéré comme incorporé dans la présente description, l'ensemble d'extrémité 1 comporte une paire d'embout coniques 2 solidaires d'une traverse et une paire d'orifices coniques 3 solidaires d'une autre traverse.  Preferably, in accordance with French patent 80 02095, the content of which is considered to be incorporated in the present description, the end assembly 1 comprises a pair of conical end pieces 2 secured to a cross member and a pair of conical orifices 3 secured to it from another cross.

Les embouts coniques 2 sont destinés à coopérer avec des portées correspondantes d'orifices coniques 4 solidaires de l'outil à prendre, tandis que les orifices coniques 3 coopèrent avec des embouts coniques 5 solidaires de l'outil à prendre. The conical tips 2 are intended to cooperate with corresponding bearing surfaces of conical orifices 4 secured to the tool to be taken, while the conical orifices 3 cooperate with conical tips 5 secured to the tool to be taken.

Après engagement respectif des portées coniques correspondantes, le verrouillage de l'outil est opéré par le blocage d'une béquille de retenue 6 solidaire de l'ensemble d'extrémité 1 contre un plot de verrouillage 7 solidaire de l'coutil à prendre. After respective engagement of the corresponding conical bearing surfaces, the tool is locked by blocking a retaining stand 6 secured to the end assembly 1 against a locking stud 7 secured to the tool to be taken.

La béquille de retenue 6 peut être tarée par un ressort 8 travaillant par compression ou actionnée par un système hydraulique 9 comportant par exemple un vérin. The retaining stand 6 can be calibrated by a spring 8 working by compression or actuated by a hydraulic system 9 comprising for example a jack.

L'essentiel est que le verrouillage soit assuré par blocage de l'extrémité de la béquille 6 contre la portée correspondante 10 du plot de verrouillage 7. The main thing is that the locking is ensured by blocking the end of the stand 6 against the corresponding bearing surface 10 of the locking stud 7.

Selon la figure 1, la béquille 6 est représentée en traits pointillés dans sa position de verrouillage. According to Figure 1, the stand 6 is shown in dotted lines in its locked position.

En référence à la figure 2, où les repères de chiffres identiques désignent des éléments identiques ou similaires à ceux de la figure 1, la béquille 6 est représentée en traits pointillés dans une position de nonverrouillage. With reference to FIG. 2, where the references of identical numbers designate elements identical or similar to those of FIG. 1, the stand 6 is shown in dotted lines in a non-locking position.

Cette position résulte par exemple de la présence d'objets solides ou d'obstacles 11 au voisinage de la portée 10 du plot de verrouillage 7. This position results for example from the presence of solid objects or obstacles 11 in the vicinity of the bearing surface 10 of the locking stud 7.

En référence aux figures 3 et 4, selon l'invention, le dispositif comporte un moyen de retenue 12, dont le bord 13 situé du côté de la portée 10 du plot 7 est en retrait d'une distance prédéterminée d. Referring to Figures 3 and 4, according to the invention, the device comprises a retaining means 12, the edge 13 located on the side of the surface 10 of the pad 7 is set back by a predetermined distance d.

La distance d entre le bord 13 et la portée 10 est de l'ordre de ou inférieure à la moitié de la longueur C d'engagement des portées coniques. The distance d between the edge 13 and the bearing surface 10 is of the order of or less than half the length C of engagement of the conical bearing surfaces.

De préférence, pour éviter tout encrassement supplémentaire sous le rebord du moyen de retenue 12, la largeur du moyen de retenue 12 est de l'ordre de ou inférieure à la largeur du plot de verrouillage 7. Preferably, to avoid any additional fouling under the rim of the retaining means 12, the width of the retaining means 12 is of the order of or less than the width of the locking stud 7.

Le moyen de retenue 12 présente une forme coopérant avec la forme de la béquille de verrouillage 6 : de préférence, on découpera cette forme par exemple rectangulaire dans une tôle ayant de préférence une épaisseur au moins égale à la moitié de celle du plot 7 et on la soudera directement sur le plot de verrouillage 7 en respectant la distance d prédéterminée. The retaining means 12 has a shape cooperating with the shape of the locking stand 6: preferably, this shape, for example rectangular, will be cut from a sheet preferably having a thickness at least equal to half that of the stud 7 and weld it directly to the locking pad 7, respecting the predetermined distance.

En référence à la figure 5, la béquille 6 de verrouillage est retenue par le bord 13 du moyen de retenue 12 lorsqu'elle n'est pas en position de blocage normal au contact de la portée 10. With reference to FIG. 5, the locking stand 6 is retained by the edge 13 of the retaining means 12 when it is not in the normal locking position in contact with the bearing 10.

La béquille 6 coopérant avec le bord 13 retient ainsi l'outil sur l'ensemble d'extrémité 1. Cependant, du fait du jeu correspondant à la distance prédéterminée d, l'outil a tendance à se déplacer lors du mouvement de la machine de terrassement. The stand 6 cooperating with the edge 13 thus retains the tool on the end assembly 1. However, due to the play corresponding to the predetermined distance d, the tool tends to move during the movement of the machine. earthworks.

Ce "flottement" de l'outil avertit ainsi le conducteur de l'engin de terrassement ; le conducteur intervient alors pour assurer le verrouillage correct de la béquille 6 sur la portée 10 et ainsi de l'coutil sur l'ensemble d'extrémité 1. Tout risque d'accident personnel ou de dommage grave pour le matériel est ainsi évité. This "floating" of the tool thus warns the operator of the earth-moving machine; the driver then intervenes to ensure the correct locking of the stand 6 on the seat 10 and thus of the tool on the end assembly 1. Any risk of personal accident or serious damage to the equipment is thus avoided.

L'invention n'est pas limitée au cas d'un ensemble de verrouillage 6, 7 constitué par une béquille 6 et un plot 7, mais englobe au contraire toute variante d'ensemble de verrouillage et de moyen de retenue 12 permettant de retenir l'outil avec un jeu d prédéterminé propre à avertir le conducteur d'engin.  The invention is not limited to the case of a locking assembly 6, 7 consisting of a crutch 6 and a stud 7, but on the contrary encompasses any variant of locking assembly and retaining means 12 making it possible to retain the 'tool with a predetermined clearance suitable for warning the machine operator.
