Abstract
Description
La présente invention est relative à un globe pour appareils d'éclairage,notamment, extérieur
Les globes connus sont réalisés en une seule pièce selon deux procédés.The present invention relates to a globe for lighting devices, in particular, exterior
The known globes are produced in a single piece according to two methods.
Selon un premier procédé, la matière plastique,sous forme de granulés, est placée dans un moule chauffé et lten semble est centrifugé.Seuls le polyéthylène, le polycarbonate et le propionate se prêtent à cette opération. According to a first process, the plastic material, in the form of granules, is placed in a heated mold and lten seems to be centrifuged. Only polyethylene, polycarbonate and propionate are suitable for this operation.
Selonsun second procédé, on extrude la matière sous la forme d'un tube borgne, qui est ensuite placé dans un moule et on achève la formation du globe par thermo-soufflage. According to a second process, the material is extruded in the form of a blind tube, which is then placed in a mold and the formation of the globe is completed by heat blowing.
Ces deux procédés ne donnent pas satisfaction. These two methods are not satisfactory.
En premier lieu, il faut signaler que ces procédés ne permettent pas de contrôler l'épaisseur de la paroi du globe et on a constaté, notamment, que celle-ci était toujours plus mince dans la région équatoriale. Firstly, it should be noted that these methods do not make it possible to control the thickness of the wall of the globe and it has been observed, in particular, that it was always thinner in the equatorial region.
En second lieu, on a constaté que les traitements physiques auxquels la matière était soumise durant la fabrication (centrifugation ou soufflage) détruisaient en partie les agents contre les rayons ultraviolets incorporés à la matière plastique.De ce fait, on assiste à une rapide destruction du globe qui devient très fragile, se craquelle et se fend,ces phénomènes étant généralement accompagnés d'une modification profonde de la couleur du globe. Secondly, it has been found that the physical treatments to which the material was subjected during manufacture (centrifugation or blowing) partially destroyed the agents against the ultraviolet rays incorporated in the plastic material. globe which becomes very fragile, cracks and splits, these phenomena being generally accompanied by a profound change in the color of the globe.
Enfin, il faut signaler aussi que ces globes,dont le diamètre est au minimum de l'ordre de quarante à cinquante centimètres, sont très encombrants ce qui pose des problèmes de stockage et de frais d'expédition lorsqu'ils doivent être livrés a' l'étranger. Finally, it should also be noted that these globes, whose diameter is at least of the order of forty to fifty centimeters, are very bulky which poses problems of storage and shipping costs when they have to be delivered to ' the stranger.
La présente invention, qui remédie à ces inconvénients, est remarquable en ce que le globe est réalisé en deux parties sensiblement hemisphériques, obtenues par injection et s'assemblant selon un plan de joint sensiblement équatorial, chacune des parties étant pourvue d'organes d'accrochage mutuel prévus dans l'épaisseur de la paroi. The present invention, which overcomes these drawbacks, is remarkable in that the globe is produced in two substantially hemispherical parts, obtained by injection and assembling according to a substantially equatorial joint plane, each of the parts being provided with organs mutual attachment provided in the thickness of the wall.
L'invention sera mieux comprise par la description qui va suivre, faite en se référant aux dessins annexés à titre d'exemple indicatif seulement, sur lesquels:
La figure 1 est une vue en élévation montrant les deux parties du globe;
La figure 2 est une vue analogue montrant les deux parties assemblees;
La figure 3 est une vue analogue montrant les deux parties du globe en position de stockage ou de transport;
La figure 4 est une vue partielle, en perspective-et à grande échelle, montrant la paroi intérieure des deux parties du globe et les organes d'accrochage;
La figure 5 est une vue analogue à celle 4, les deux parties étant vues de l'extérieur;
La figure 6 est une vue partielle, vue de l'intérieur, montrant le début de l'assemblage des deux parties;;
La figure 7 est une vue analogue à celle 6 montrant les deux parties assemblées;
La figure 8 est une vue en coupe effectuée selon la ligne
VIII-VIII de la figure 6;
La figure 9 est une vue en coupe effectuée selon la ligne

Figure 7 is a view similar to that 6 showing the two parts assembled;
Figure 8 is a sectional view taken along the line
VIII-VIII of Figure 6;
Figure 9 is a sectional view taken along the line
IX-IX of figure 7.
En se reportant aux dessins, on voit que le globe est obtenu par l'assemblage, sans solution de continuité visible, de deux parties 1 et 2 réalisées en une matière plastique injectée. Referring to the drawings, it can be seen that the globe is obtained by assembling, without visible continuity, two parts 1 and 2 made of an injected plastic.
Dans l'exemple représenté, les deux parties sont sensiblement hémisphériques et le plan de joint est équatorial. In the example shown, the two parts are substantially hemispherical and the joint plane is equatorial.
De la façon connue, le globe présente un orifice à sa partie inférieure et une collerette de fixation non visible sur les dessins. In known manner, the globe has an opening at its lower part and a fixing flange not visible in the drawings.
Pour chacune des parties 1 et 2, le plan de joint est matérialisé par le bord 3. For each of parts 1 and 2, the joint plane is materialized by edge 3.
Chacune des parties présente une succession de logements 4, débouchant sur le bord 3 et à l'intérieur de la partie correspondante, séparés par des pattes 5 s'étendant au-delà du bord 3. Each of the parts has a succession of housings 4, opening onto the edge 3 and inside the corresponding part, separated by lugs 5 extending beyond the edge 3.
Comme montre sur les dessins,les dimensions des logements et des pattes sont telles que lorsque les deux parties sont scrposes et que les bords 3 sont en contact les pattes 5 d'une partie pénètrent librement dans le logement 4 de l'autre. As shown in the drawings, the dimensions of the housings and of the legs are such that when the two parts are scrposed and the edges 3 are in contact, the legs 5 of one part freely penetrate into the housing 4 of the other.
A ce stade, les deux parties sont parfaitement centrés l'une par rapport à l'autre et on pourrait alors concevoir un assemblage par collage. At this stage, the two parts are perfectly centered with respect to each other and one could then design an assembly by gluing.
Selon une autre caractéristique de l'invention, on préfère réaliser un assemblage démontable. According to another characteristic of the invention, it is preferred to produce a dismountable assembly.
A cet effet, chaque patte présente à son extrémité un épaulement 6, prévu sur la face externe de ladite patte, susceptible lorsque les deux parties sont assemblées, comme décrit ci-dessus, de venir prendre appui par une rotation partielle desdites parties en sens inverse l'une de l'autre,sous un épaulement 7 prévu dans le logement 4 de l'autre partie. To this end, each tab has at its end a shoulder 6, provided on the external face of said tab, capable when the two parts are assembled, as described above, to come to bear by a partial rotation of said parts in opposite directions one from the other, under a shoulder 7 provided in the housing 4 of the other part.
Comme montré sur les dessins, les épaulements 6 et 7 sont légèrement obliques par rapport au plan de joint de façon à former des rampes ayant pour effet de-serrer lFun contre l'autre les bords 3 des parties 1 et 2. As shown in the drawings, the shoulders 6 and 7 are slightly oblique with respect to the joint plane so as to form ramps having the effect of tightening the edges 3 of the parts 1 and 2 against each other.
Selon une variante, on peut prévoir sur les épbulements 7 une encoche 8 ( figure 4) dans laquelle, en fin de rotation, peut s'engager, par une déformation élastique de la matière, un bossage9 prévu sur les épaulements 6 des pattes 5 de l'autre partie ( figure 5). Alternatively, one can provide on the projections 7 a notch 8 (Figure 4) in which, at the end of rotation, can engage, by an elastic deformation of the material, a boss9 provided on the shoulders 6 of the legs 5 of the other part (figure 5).
I1 faut noter que la conception des organes d'assemblage est telle que les deux parties 1 et 2 sont absolument identiques et qu'au niveau du plan de joint, le même moule peut etre utilisé pour réaliser l'une ou l'autre desdites parties. It should be noted that the design of the assembly members is such that the two parts 1 and 2 are absolutely identical and that at the joint plane, the same mold can be used to make one or the other of said parts. .
I1 faut noter, aussi, que la conception du globe permet d'accèder à l'intérieur avant assemblage pour y fixer des éléments spéciaux ou décoratifs qui ne passeraient pas par le trou inférieur de la fixation du globe sur son socle. It should also be noted that the design of the globe allows access to the interior before assembly to attach special or decorative elements which would not pass through the lower hole in the attachment of the globe to its base.
Bien entendu, la présente invention ne se limite pas au mode de réalisation décrit et représenté mais s'étend, au contraire, à toutes variantes de formes et dimensions. Of course, the present invention is not limited to the embodiment described and shown but extends, on the contrary, to all variants of shapes and dimensions.
C'est ainsi, entre autres, que sans sortir du cadre de l'invention, on peut réaliser des "globes" oblongs ou tronconiques en deux parties ou en trois par l'interposition, entre les parties 1 et 2,d'une virole cylindrique ou tronconique (non représentée). Thus, among other things, without departing from the scope of the invention, it is possible to produce oblong or frustoconical "globes" in two parts or in three by the interposition, between parts 1 and 2, of a ferrule cylindrical or frustoconical (not shown).
Naturellement, ce globe peut être utilise pour des appareils d'éclairage intérieur. Naturally, this globe can be used for interior lighting fixtures.
