Abstract
Description
Le brevet principal a pour objet une cosse pour élingue qui comprend un premier élément en croissant, deux flasques latéraux sensiblement plans réunis par une gorge, et un deuxième élément, formant étai, qui est fixé à l'intérieur du premier élément et délimite une ouverture pour le passage d'un élément de suspension, tel qu'un crochet. The main patent relates to a sling lug which comprises a first crescent element, two substantially flat lateral flanges joined by a groove, and a second element, forming a forestay, which is fixed inside the first element and delimits an opening. for the passage of a suspension element, such as a hook.
Lors du montage de cette cosse, on enfile l'élément en croissant dans l'oeil d'un crochet, par exemple, et on soude ensuite l'étai à l'intérieur de cet élément. When mounting this terminal, the crescent element is threaded into the eye with a hook, for example, and the forestay is then welded inside this element.
Le premier certificat d'addition a pour objet un perfec tionnement apporté à cette cosse, selon'lequel la gorge a une profondeur suffisamment grande pour que les extrémités des bords des flasques constituent des butées limitant le pivotement du crochet et empbehant ceSui-ci de se dégager de l'élément en croissant. The first certificate of addition relates to an improvement made to this terminal, according to which the groove has a depth large enough for the ends of the edges of the flanges to constitute stops limiting the pivoting of the hook and preventing it from release from the crescent element.
La présente addition a pour objet un autre perfectionnement qui permet d'améliorer encore les conditions dans lesquelles la cosse travaille. The present addition relates to another improvement which makes it possible to further improve the conditions under which the terminal works.
Selon cette addition, la cosse est associée à un élément de suspension qui -comporte, dispose de part et d'autre de la cosse, deux bossages limitant le débattement latéral de cette cosse. According to this addition, the terminal is associated with a suspension element which comprises, has on either side of the terminal, two bosses limiting the lateral movement of this terminal.
L'élément de suspension peut être constitué par exemple par un crochet ou une manille. The suspension element can be constituted for example by a hook or a shackle.
On a décrit ci-après, à titre d'exemple non limitatif, deux modes de réalisation de l'invention avec référence au dessin annexé dans lequel :
La Figure 1 est une vue en coupe de la cosse, avant mise en place et sertissage du ciblez dans un premier mode de réalisa tion,
La Figure 2 est une vue semblable à la Figure 1, dans un second mode de réalisation,
A la Figure 1 on retrouve l'élément en croissant 1 et l'étai 3 qui a été soudé dans l'élément 1, après enfilage de ce dernier dans l'oeil dun crochet 5. Two embodiments of the invention have been described below, by way of non-limiting example, with reference to the appended drawing in which:
FIG. 1 is a sectional view of the terminal, before positioning and crimping of the target in a first embodiment,
Figure 2 is a view similar to Figure 1, in a second embodiment,
In FIG. 1 we find the crescent element 1 and the forestay 3 which has been welded in the element 1, after threading of the latter in the eye of a hook 5.
Nais le crochet 5 auquel est associé la cosse comporte sur sa périphérie extérieure deux bossages 9 qui sont disposés de part et d'autre de la cosse et limitent le débattement latéral de cette cosse,
Dans le mode de réalisation de la Figure 2, le crochet 5 a été remplacé par une manille 3:0 dont la périphérie extérieure porte deux bossages 11 analogues aux bossages 9.Nais the hook 5 with which the terminal is associated has on its outer periphery two bosses 9 which are arranged on either side of the terminal and limit the lateral movement of this terminal,
In the embodiment of FIG. 2, the hook 5 has been replaced by a 3: 0 shackle, the outer periphery of which carries two bosses 11 similar to the bosses 9.
I1 va de soi-que la présente addition ne doit pas être considérée comme limitée aux modes. de réalisation décrits et représentés, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present addition should not be considered as limited to the modes. described and shown, but covers, on the contrary, all variants.
