Abstract

Le crochet faisant l'objet de la présente invention comporte un crochet 5 dans lequel est logée une rotule 2 pourvue d'un logement pour le pivot de l'outil à accrocher; il est prévu un dispositif de blocage, pour bloquer le pivot dans son logement, comportant une dent 41 qui peut tourner autour de l'axe fixe d'un premier pivot 6. La dent, dans sa position de blocage, déborde sur le logement ménagé dans la rotule qui est pourvue d'une fente 2b susceptible de permettre le passage de la dent elle-même ; la dent est constamment poussée dans sa position de blocage par un ressort 3 plat qui est logé dans une rainure 5a prévue dans le corps-crochet L'une des extrémités du ressort 3 est insérée dans une rainure 2a ménagée dans la rotule 2. La dent et l'extrémité du ressort empêchent la rotation de la rotule autour de son propre axe et sa sortie du corps-crochet. La dent peut tourner à l'aide d'un bras de levier 42 qui peut être relié à la dent elle-même, soit directement, soit par un système de leviers comportant un deuxième pivot 90 qui présente une surface excentrique faisant fonction de came. Le crochet en question sert à accrocher de manière rapide et automatique un outil un tracteur.The hook forming the subject of the present invention comprises a hook 5 in which is housed a ball joint 2 provided with a housing for the pivot of the tool to be hooked; a locking device is provided, for locking the pivot in its housing, comprising a tooth 41 which can rotate about the fixed axis of a first pivot 6. The tooth, in its locking position, projects over the housing provided in the patella which is provided with a slot 2b capable of allowing the passage of the tooth itself; the tooth is constantly pushed into its locking position by a flat spring 3 which is housed in a groove 5a provided in the hook body One end of the spring 3 is inserted in a groove 2a formed in the ball 2. The tooth and the end of the spring prevent the rotation of the ball about its own axis and its exit from the hook body. The tooth can rotate by means of a lever arm 42 which can be connected to the tooth itself, either directly or by a system of levers comprising a second pivot 90 which has an eccentric surface acting as a cam. The hook in question is used to quickly and automatically hook a tool to a tractor.
