Description

Enjoliveur pour briquet ou similaire constitué de deux demicoquilles.Wheel cover for lighter or similar consisting of two half-shells.

L'invention concerne un enjoliveur pour briquet ou similaire constitué de deux demi-coquilles. Un tel enjoliveur appele également cache-briquet, est destiné à recouvrir un objet banal, tel qu'un briquet jetable, pour lui donner l'aspect d'un objet luxueux. Cet enjoliveur, qui est par exemple en métal argenté, peut constituer un objet d'art ou un produit publicitaire.The invention relates to a cover for a lighter or the like consisting of two half-shells. Such a hubcap also called lighter cover, is intended to cover an ordinary object, such as a disposable lighter, to give it the appearance of a luxurious object. This hubcap, which is for example made of silver metal, can constitute an art object or an advertising product.

Un type connu d'enjoliveur du commerce est constitué par une coquille creuse unique dans laquelle l'objet à cacher, tel que le briquet jetable, peut être introduit par coulissement et en être extrait lorsqu'il doit être changé. La partie supérieure de l'objet doit rester extérieure à la coquille pour permettre cette extraction, ce qui nuit à l'esthétique de l'ensemble.A known type of commercial hubcap consists of a single hollow shell in which the object to be hidden, such as the disposable lighter, can be slid in and out when it needs to be changed. The upper part of the object must remain outside the shell to allow this extraction, which affects the aesthetics of the whole.

Les précisions doivent être élevées pour assurer le serrage de l'objet. En outre, la coquille ne peut être moulée qu'avec des systèmes à tiroirs, ce qui augmente les coûts d'outillage et de fabrication.The details must be high to ensure the tightening of the object. In addition, the shell can only be molded with drawer systems, which increases tooling and manufacturing costs.

On connaît également dans le commerce des enjoliveurs constitués de deux demi-coquilles reliées par une articulation avec un ressort de rappel en fermeture. La construction d'un tel ensemble est compliquée, fragile et coûteuse. En outre, l'articulation est difficile à cacher, ce qui diminue l'aspect de l'ensemble.There are also known in the trade hubcaps consisting of two half-shells connected by an articulation with a return spring when closing. The construction of such an assembly is complicated, fragile and expensive. In addition, the joint is difficult to hide, which decreases the appearance of the whole.

On connaît en outre, également dans le commerce, des enjoliveurs constitués de deux demi-coquilles qui sont réunies par un ou plusieurs liens extérieurs tels que des ceintures élastiques. L'esthétique de tels enjoliveurs est mauvaise et le démontage-remontage des liens est fastidieux.Also known, also commercially, hubcaps consisting of two half-shells which are joined by one or more external links such as elastic belts. The aesthetics of such hubcaps is poor and the disassembly and reassembly of the links is tedious.

La présente invention vise en conséquence à fournir un nouvel enjoliveur qui ne présente pas les inconvénients des enjoliveurs connus décrits ci-dessus. The present invention therefore aims to provide a new hubcap which does not have the drawbacks of the known hubcaps described above.

A cet effet, l'enjoliveur selon l'invention est caractérisé en ce que les deux demi-coquilles sont réunies par un ressortlame précambré logé dans deux évidements des demi-coquilles, ledit ressort-lame comportant un trou central dans lequel pénètre un organe de maintien solidaire des deux demicoquilles.To this end, the hubcap according to the invention is characterized in that the two half-shells are joined by a pre-cam leaf spring housed in two recesses of the half-shells, said leaf spring comprising a central hole into which a member of joint support of the two half-shells.

De préférence, ledit organe de maintien est constitué par de la matière de chacune des demi-coquilles formant le bord d'un demi-alésage formé dans une paroi de chaque évidement sensiblement coaxialement au trou du ressort-lame et de plus petit diamètre qui celui-ci, lesdits bords étant chassés au moyen d'un outil conique pour produire un rivetage.Preferably, said holding member is constituted by material from each of the half-shells forming the edge of a half-bore formed in a wall of each recess substantially coaxially with the hole of the leaf spring and of smaller diameter than that here, said edges being driven out by means of a conical tool to produce riveting.

Selon une forme de réalisation de l'invention, les demicoquilles comprennent des nervures internes de centrage de l'objet contenu.According to one embodiment of the invention, the half shells comprise internal ribs for centering the contained object.

L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dont la figure unique est une vue schématique en coupe longitudinale transversale de la partie inférieure d'un enjoliveur selon un exemple de réalisation de l'invention. The invention will be clearly understood on reading the following description made with reference to the appended drawing, the single figure of which is a schematic view in transverse longitudinal section of the lower part of a hubcap according to an exemplary embodiment of the invention.

L'enjoliveur selon l'invention comprend deux demi-coquilles 1, 2 moulées par exemple en alliage de zinc avec une base 3, 4 relativement épaisse et une paroi latérale 5, 6 mince délimitant des volumes intérieurs 7, 8 qui forment, lorsque les deux demi-coquilles 1, 2 sont accolées, un volume intérieur ouvert vers le haut et destiné à contenir un objet tel qu'un briquet jetable (non représenté).The hubcap according to the invention comprises two half-shells 1, 2 molded for example from zinc alloy with a relatively thick base 3, 4 and a thin side wall 5, 6 delimiting interior volumes 7, 8 which form, when the two half-shells 1, 2 are placed side by side, an interior volume open upwards and intended to contain an object such as a disposable lighter (not shown).

Conformément à l'invention, les demi-coquilles 1, 2 sont réunies par un ressort-lame précambré 9 logé dans des évidements 10, 11 respectifs des fonds 3, 4 des demicoquilles, avec sa concavité dirigée vers les volumes 7, 8. Le ressort-lame 9 comporte un trou central 12 disposé coaxial à deux demi-alésages 13, 14 ménagés respectivement dans la paroi des évidements 10, 11 opposée aux fonds 3, 4. Le diamètre des demi-alésages 13, 14 est inférieur à celui du trou 12.According to the invention, the half-shells 1, 2 are joined by a precambered leaf spring 9 housed in respective recesses 10, 11 of the bottoms 3, 4 of the half-shells, with its concavity directed towards the volumes 7, 8. The leaf spring 9 has a central hole 12 arranged coaxial with two half-bores 13, 14 formed respectively in the wall of the recesses 10, 11 opposite the bottoms 3, 4. The diameter of the half-bores 13, 14 is less than that of the hole 12.

Après positionnement des demi-coquilles 1, 2 face à face, un outil conique est enfoncé dans l'alésage 13, 14 de manière à chasser la matière du bord de cet alésage dans le trou 12 du ressort-lame 9 pour former un rivetage. Le ressort-lame 9 tend, par sa précontrainte, à rapprocher l'une de l'autre les demi-coquilles 1, 2 en enserrant l'objet. Le serrage et le centrage de cet objet sont encore améliorés par des nervures intérieures formées dans les volumes intérieurs 7, 8. L'objet peut être complètement enfermé entre les demi-coquilles 1, 2, sans partie saillante, ce qui permet d'obtenir une esthétique optimale. L'extraction se fait par un léger écartement des demi-coquilles 1, 2, par exemple à l'aide d'un trombone.After positioning the half-shells 1, 2 face to face, a conical tool is pressed into the bore 13, 14 so as to drive the material from the edge of this bore into the hole 12 of the leaf spring 9 to form a riveting. The leaf spring 9 tends, by its preload, to bring the half-shells 1, 2 closer to one another by enclosing the object. The tightening and centering of this object are further improved by internal ribs formed in the interior volumes 7, 8. The object can be completely enclosed between the half-shells 1, 2, without a projecting part, which makes it possible to obtain optimal aesthetics. The extraction is done by a slight spacing of the half-shells 1, 2, for example using a paper clip.

L'écartement entre les demi-coquilles 1, 2 peut être pratiquement nul, leur écartement produisant en effet un déplacement sensiblement parallèle grâce à la déformation du ressort-lame 9. L'esthétique peut ainsi être optimisée.The spacing between the half-shells 1, 2 can be practically zero, their spacing in effect producing a substantially parallel displacement thanks to the deformation of the leaf spring 9. The aesthetics can thus be optimized.

Les demi-coquilles 1, 2 sont avantageusement moulées en alliage de zinc, avec les volumes intérieurs 7, 8 et les évidements 10, 11, dans un moule à plat de réalisation simple.The half-shells 1, 2 are advantageously molded from a zinc alloy, with the interior volumes 7, 8 and the recesses 10, 11, in a flat mold of simple production.

Les demi-coquilles 1, 2 sont ensuite argentées sur leur face externe. The half-shells 1, 2 are then silvered on their external face.
