Abstract

The present invention relates to an assembly component device made from metal, specifically non-rotational and inextractable after moulding in any technical plastic materials intended for the manufacture of components or of industrial objects requiring the use of highly reliable fixing means.

Description

La présente invention concerne un dispositif de composant d'assemblage, en métal, spécifiquement antirotatif et inextrac tible après surmoulage dans toutes matières plastiques techniques destinées à la fabrication de pièces ou d'objets industriels, nécessitant l'emploi de moyens de fixation hautement fiable. The present invention relates to an assembly component device, made of metal, specifically anti-rotating and inextrac tible after overmolding in all technical plastics intended for the manufacture of parts or industrial objects, requiring the use of highly reliable fixing means.

3ans le domaine considéré, après multiples recherches brevets français et européens - il n'apparait aucune antériorité à retenir, en l'espèce. 3 In the field under consideration, after multiple searches for French and European patents - there does not appear to be any prior art in this case.

Ceci étant, ledit dispositif, innovant, comporte l'avantage d'un ancrage on ne peut plus solide, dont la structure a faculté de pouvoir entre proportionnée aux forces qu'il devra subir, tant au plan du couple quta celui de la traction, et ce, selon les applications auxquelles l'utilisateur le destinerait. That said, said device, innovative, has the advantage of an anchoring which could not be more solid, the structure of which has the faculty of being able to be proportionate to the forces which it will have to undergo, both in terms of the torque quta that of the traction, and this, depending on the applications to which the user intended it.

l'ancrage de ce dispositif a pour caractéristiques principales, qu'il est : massif, cruciforme, et modulable. the anchoring of this device has the main characteristics that it is: massive, cruciform, and modular.

En effet, cet ancrage est modulable, car les branches de sa partie cruciforme peuvent, toutes - ou seulement par paires -, être prolongées ainsi que réduites en diamètre dans le sens de leur hauteur pour, à leur extrémité, se terminer par une section plane en parallèle avec la base du dispositif (fig 4). Indeed, this anchoring is modular, because the branches of its cruciform part can, all - or only in pairs -, be extended as well as reduced in diameter in the direction of their height to, at their end, end in a flat section in parallel with the base of the device (fig 4).

La figure 1 représente le dispositif dans sa version goujon fileté,
La figure 2 représente le dispositif dans sa version douille taraudée,
La figure 3 représente le dispositif en plan, vu par sa base,
La figure 4 représente le dispositif dans sa version goujon fileté à ancrage cruciforme en saillie - à la base - pourvu de branches allongées à diamètre décroissant et section plane en haut,
La figure 5 représente le dispositif dans sa version goujon fileté à ancrage cruciforme en saillie, pourvu de branches de faible hauteur,
Les figures 6, 7 et 8 représentent le dispositif dans sa version plate, en plan (fig 6) en perspective (fig 7) en coupe (fig 8).FIG. 1 represents the device in its threaded stud version,
FIG. 2 shows the device in its tapped bushing version,
FIG. 3 represents the device in plan, seen from its base,
FIG. 4 shows the device in its threaded stud version with projecting cruciform anchoring - at the base - provided with elongated branches of decreasing diameter and planar section at the top,
FIG. 5 shows the device in its threaded stud version with protruding cruciform anchor, provided with branches of low height,
Figures 6, 7 and 8 show the device in its flat version, in plan (fig 6) in perspective (fig 7) in section (fig 8).

Nota : les goujon et douille peuvent aussi être réalisés en version raccord tubulaire et douille à trou débouchant. Note: the stud and socket can also be produced in a tubular connection and socket with through hole version.

Le dispositif représenté figure 1, version goujon, usiné en une seule pièce, comprend :
- une partie filetée, pouvant indifféremment, suivant demande, recevoir un filetage - ou un taraudage : douille (fig 2) à l'un quelconque des pas connus utilisés dans les industries françaises ou étrangères,
- un corps principal, disposant :
en tête, d'une collerette,
au milieu, d'une partie cylindrique,
à à la base, d'un ancrage cruciforme à quatre branches
de même hauteur, et ayantun diamètre constant, lequel
peut être égal ou différent de celui de la collerette.The device shown in Figure 1, stud version, machined in one piece, includes:
- a threaded part, which can indifferently, upon request, receive a thread - or a tapping: socket (fig 2) in any of the known pitches used in French or foreign industries,
- a main body, with:
at the head, with a collar,
in the middle, of a cylindrical part,
at the base, a cruciform anchor with four branches
of the same height, and having a constant diameter, which
may be equal to or different from that of the collar.

A noter que les hauteurs, respectives, des collerette partie intermédiaire cylindrique et ancrage, peuvent être égales ou non. Note that the respective heights of the cylindrical intermediate portion and anchoring flange may or may not be equal.

le dispositif selon l'invention, compte tenu des spécif-cités énoncées, apporte donc, d'une part une pluralité d'adaptations conceptuelles, et, d'autre part plus ie sécurité dans les moyens d'attache mis en oeuvre, traditionnellement, dans les innombrables et diverses inaustries utilisatrices, -en France comme à ltéchet--n mondial. the device according to the invention, taking into account the specificities mentioned, therefore provides, on the one hand a plurality of conceptual adaptations, and, on the other hand, more safety in the attachment means implemented, traditionally, in the innumerable and diverse user industries, - in France as well as in the world - n worldwide.

Claims

REYENDICATIONS
