Description
<Desc/Clms Page number 1> <Desc / Clms Page number 1>
La présente invention concerne un élément de construction structurel de forme allongée conçu pour supporter des charges, fabriqué en métal et en matière plastique par surmoulage, destiné à être utilisé sur des véhicules, des appareils électroménagers, des meubles et similaires. The present invention relates to an elongated structural building element designed to support loads, made of metal and plastic by overmolding, for use on vehicles, household appliances, furniture and the like.
Cet élément combine un corps de base allongé, creux et ouvert d'un côté, fait en tôle métallique, et une partie en matière plastique incorporée au corps de base par surmoulage, qui comprend un treillis de nervures de renforcement transversales à l'intérieur du corps de base, et des moyens de liaison des deux parties en plastique sur le corps en métal, faits dans le même plastique pendant le même processus de moulage. This element combines an elongated base body, hollow and open on one side, made of metal sheet, and a plastic part incorporated into the base body by overmolding, which comprises a lattice of transverse reinforcing ribs inside the base body, and means for connecting the two plastic parts to the metal body, made of the same plastic during the same molding process.
ETAT ANTERIEUR DE LA TECHNIQUE
Un exemple de poutre creuse en forme de gaine, faite sur un corps de base creux en tôle métallique emboutie, et avec des nervures de renforcement en plastique surmoulées, est divulgué dans le document EP-3 703 42-Bl. Par la technique de surmoulage sur un corps métallique, on obtient en élément structurel, par exemple pour la construction de composants automobiles, qui, tout en étant léger, est rigide et supporte bien les charges de compression. Les nervures de renforcement s'étendent tout au long de l'élément de construction connu, croisées et raccordée entre elles à l'intérieur du creux du corps métallique, celles-ci étant raccordées à ces parois latérales en tôle par des ancrages dans le même plastique surmoulé que les nervures de renforcement, qui ont été façonnées dan la même opération de moulage à travers des orifices de passage de ces parois latérales. PRIOR STATE OF THE ART
An example of a hollow sheath in the form of a sheath, made on a hollow base body of stamped metal sheet, and with overmolded plastic reinforcing ribs, is disclosed in document EP-3 703 42-B1. By the technique of overmolding on a metallic body, a structural element is obtained, for example for the construction of automobile components, which, while being light, is rigid and withstands well the compression loads. The reinforcing ribs extend throughout the known building element, crossed and connected together inside the hollow of the metal body, these being connected to these lateral sheet metal walls by anchors in the same plastic overmolded as the reinforcing ribs, which have been shaped in the same molding operation through orifices for passage of these side walls.
EXPOSE DE L'INVENTION
Selon la présente invention, l'élément structurel du type défini est caractérisé en ce que le corps de base est formé d'un creux entre deux parois latérales, chacune d'elles étant dotée d'un rebord, et la partie en matière plastique comprend en plus un revêtement à partir duquel s'étendent au moins une partie des moyens de liaison reliant le corps de base avec ces nervures de renforcement, au-dessus des bords des parois latérales. STATEMENT OF THE INVENTION
According to the present invention, the structural element of the defined type is characterized in that the basic body is formed by a hollow between two side walls, each of which is provided with a flange, and the plastic part comprises in addition a coating from which extend at least part of the connecting means connecting the base body with these reinforcing ribs, above the edges of the side walls.
L'avantage de l'élément de construction composé selon l'invention par rapport à l'élément de construction connu réside dans la disposition des nervures de renforcement, qui sont simples et peu encombrantes étant donné qu'elles ne sont pas conditionnées par des perforations sur la base métallique comme c'est le cas dans l'état de la technique cité, en permettant ainsi un meilleur ajustement des épaisseurs. The advantage of the building element composed according to the invention compared to the known building element lies in the arrangement of the reinforcing ribs, which are simple and compact since they are not conditioned by perforations on the metal base as is the case in the state of the art cited, thus allowing better adjustment of the thicknesses.
<Desc/Clms Page number 2> <Desc / Clms Page number 2>
Selon d'autres caractéristiques avantageuses, le treillis de nervures transversales comprend des nervures perpendiculaires ou croi- sées aux parois latérales du corps de base, dépassant la hauteur de ces bords latéraux. La partie en matière plastique est projetée vers l'intérieur creux du corps de base à travers plusieurs orifices pour former une série de boutons d'ancrage. According to other advantageous characteristics, the lattice of transverse ribs includes ribs perpendicular or crossed to the side walls of the base body, exceeding the height of these side edges. The plastic part is projected towards the hollow interior of the base body through several orifices to form a series of anchoring buttons.
L'invention, par l'intermédiaire de la conception des ancrages, a un objectif additionnel, à savoir faciliter la séparation des deux matériaux acier et plastique, dans le processus de broyage préalable à l'opération de recyclage à laquelle sera soumis l'élément structurel composé lorsqu'il ne sera plus utilisé. The invention, through the design of the anchors, has an additional objective, namely to facilitate the separation of the two steel and plastic materials, in the grinding process prior to the recycling operation to which the element will be subjected. structural compound when it is no longer in use.

REALISATION PREFERENTIELLE DE L'INVENTION
En ce qui concerne les figures 1-4, l'élément 1 de construction mixte représenté en réalisation préférentielle, comprend un corps de base 2 creux fabriqué en tôle emboutie et pourvu d'un fond 2a fermé et de deux parois latérales 2b, un treillis 3 de nervures 3a, 3b de renforcement fabriquées en plastique surmoulé sur le creux intérieur du corps de base, un revêtement 4 dans le même plastique que les nervures et surmoulé dans la même opération d'injection du plastique, sur la superficie extérieure du corps de base 2, avec des moyens 5 de liaison du treillis 3 de nervures à ces parois 2b latérales et des moyens 6 d'ancrage du revêtement 4 au corps de base 2. PREFERENTIAL IMPLEMENTATION OF THE INVENTION
As regards Figures 1-4, the element 1 of mixed construction shown in preferred embodiment, comprises a hollow base body 2 made of stamped sheet metal and provided with a closed bottom 2a and two side walls 2b, a trellis 3 of ribs 3a, 3b of reinforcement made of plastic overmolded on the interior hollow of the base body, a coating 4 in the same plastic as the ribs and overmolded in the same injection operation of the plastic, on the external surface of the body of base 2, with means 5 for connecting the mesh 3 of ribs to these lateral walls 2b and means 6 for anchoring the covering 4 to the base body 2.
Le corps de base 2, à coupe en U par exemple, possède deux parois 2b latérales planes pourvues d'un rebord 7 respectif (figure 1 et 3), lequel peut être droit ou replié vers l'extérieur. Le revêtement 4 extérieur en plastique s'étend sur la superficie extérieure du fond 2a et des deux parois latérales et dépasse les rebords 7 des parois latérales, pour former sur eux pendant la même opération de surmoulage un rabat 4a en plastique dans le même revêtement. Le treillis 3 de nervures comprend une série de nervures transversales 3a, 3b regroupées en modules ou in- The base body 2, in U-cut for example, has two flat side walls 2b provided with a respective flange 7 (FIGS. 1 and 3), which can be straight or folded outwards. The outer plastic coating 4 extends over the outer surface of the bottom 2a and the two side walls and exceeds the edges 7 of the side walls, to form on them during the same molding operation a plastic flap 4a in the same coating. The trellis 3 of ribs comprises a series of transverse ribs 3a, 3b grouped in modules or in-
<Desc/Clms Page number 3><Desc / Clms Page number 3>
dépendantes les unes des autres, disposées tout au long du corps de base à des intervalles 9 de séparation déterminés en fonction de la répartition des charges soumises. Chacun de ces modules, 3a, 3b, de nervures combinées comprend un couple de nervures 3a et deux nervures 3b croisées entre ce couple de nervures. Dans un exemple de réalisation, le treillis 3 ne comprend que des nervures 3a perpendiculaires aux parois latérales 2b ou que des nervures 3b croisant ces parois. dependent on each other, arranged throughout the base body at intervals 9 of separation determined as a function of the distribution of the loads subjected. Each of these modules, 3a, 3b, of combined ribs comprises a pair of ribs 3a and two ribs 3b crossed between this pair of ribs. In an exemplary embodiment, the trellis 3 only comprises ribs 3a perpendicular to the side walls 2b or only ribs 3b crossing these walls.
Toutes les nervures 3a, 3b s'étendent du fond matallique 2a du corps, en contact avec lui, à la hauteur des parois latérales 2b. ces deux types de nervures 3a, 3b dépassent la hauteur des parois latérales 2b et s'étendent jusqu'à se relier avec le rabat 4a (figure 4) sur les rebords 7 en tôle, en enfermant le corps métallique 2 entre les nervures 3a, 3b et le revêtement 4. All the ribs 3a, 3b extend from the metallic bottom 2a of the body, in contact with it, at the height of the side walls 2b. these two types of ribs 3a, 3b exceed the height of the side walls 2b and extend until they connect with the flap 4a (FIG. 4) on the edges 7 made of sheet metal, enclosing the metal body 2 between the ribs 3a, 3b and the coating 4.
Le fond 2a du corps de base a des orifices 8, entre les nervures 3, ou 3a et 3b, pour laisser passer pendant le processus de surmoulage, le plastique du revêtement 4 jusqu'au trou du corps de base 2 et former sur chacun des orifices 8 un bouton 6 d'ancrage qui fixe le revêtement 4 au corps de base 2 en tôle, et qui renforce en même temps le joint des nervures 3a, 3b. L'ancrage au moyen des boutons 6 est amélioré par un façonnage des bords métalliques des orifices 8, non représenté sur les dessins. The bottom 2a of the base body has holes 8, between the ribs 3, or 3a and 3b, to allow the plastic of the coating 4 to pass during the molding process up to the hole of the base body 2 and form on each of the orifices 8 a button 6 for anchoring which fixes the covering 4 to the base body 2 made of sheet metal, and which at the same time strengthens the joint of the ribs 3a, 3b. The anchoring by means of the buttons 6 is improved by shaping the metal edges of the orifices 8, not shown in the drawings.
