Description

La présente invention concerne les boîtiers de lampes électriques de poche alimentées par piles.The present invention relates to the housings of electric pocket lamps powered by batteries.

Il est de plus en plus connu de substituer aux boîtiers métalliques de lampe de poche des boîtiers réalisés en matière plastique afin de remédier aux inconvénients que ceux-là présentaient. En effet, d'une part un mauvais fonctionnement était généralement dû à de mauvais contacts ou une mauvaise isolation de certains éléments; d'autre part, les boîtiers métalliques étaient souvent détériorés par l'oxydation rapide engendrée par la décomposition des piles déchargée qu'- ils contenaient au bout d'un certain temps de non utilisation.Si l'emploi des matériaux plastiques a pu remédier au second inconvénient cité, les réalisationsactuellement connues utilisent toujours le même type de contacts, consistant à mettre chacune des bornes de la pile en liaison permanente avec une lame métallique flexible dont l'- une aboutit à l'extrémité du culot de l'ampoule et l'autre vient en appui sur la partie cylindrique de la douille par déformation élastique sous l'action d'un bouton poussoir mobile en translation, fermant ainsi le circuit électrique. Ces lames de contact sont soit incorporées dans le moule avant l'injection de la matière plastique, soit introduites après démoulage du boîtier dans des logements prévus à cet effet. L'un et l'autre de ces modes de fabrication ont l'inconvénient d'être onéreux et d'être souvent détériorés dans les zones d'implantation des lames de contact en raison de la variation d'élasticité des matériaux plastiques sous l'influence des basses températures ou du vieillissement.It is increasingly known to replace metal flashlight housings with housings made of plastic material in order to remedy the drawbacks that these presented. On the one hand, a malfunction was generally due to poor contacts or poor insulation of certain elements; on the other hand, the metal cases were often deteriorated by the rapid oxidation caused by the decomposition of the discharged batteries which they contained after a certain period of non-use. If the use of plastic materials could remedy the second disadvantage cited, the currently known embodiments always use the same type of contacts, consisting in putting each of the battery terminals in permanent connection with a flexible metal blade, one of which ends at the end of the base of the bulb and the '' comes to rest on the cylindrical part of the sleeve by elastic deformation under the action of a push button movable in translation, thus closing the electrical circuit. These contact blades are either incorporated into the mold before injection of the plastic material, or introduced after demolding the housing in housings provided for this purpose. Both of these manufacturing methods have the disadvantage of being expensive and of being often deteriorated in the areas of implantation of the contact blades due to the variation in elasticity of the plastic materials under the influence of low temperatures or aging.

Pour éviter la présence de lames de contact, le brevet US 1.404.077 prévoit une pile amovible dans le boîtier d'une lampe électrique. On ferme ou ouvre le circuit électrique pile-ampoule électrique en actionnant un poussoir extérieur au boîtier qui permet de déplacer axialement la pile afin de mettre le plot de la pile en contact ou hors contact avec le culot de l'ampoule. Un tel système étant conçu uniquement pour les piles cylindriques, et n'étant aucunement prévu pour être réalisé en matière plastique,ne résout pas les problèmes exposés ci-dessus.To avoid the presence of contact blades, US Patent 1,404,077 provides a removable battery in the housing of an electric lamp. The electric circuit battery-light bulb is closed or opened by actuating a push button outside the housing which allows the battery to be moved axially in order to put the battery pad in contact or out of contact with the base of the bulb. Such a system being designed only for cylindrical cells, and not being in any way intended to be made of plastic material, does not solve the problems set out above.

On connaît aussi des lampes de poche telles que celles décrites dans le brevet FR 69.16.548, qui comportent une pièce d'un seul tenant destinée à la fixation de la tête éclairante ainsi qu'au logement de l'ampoule, ladite pièceétant faite en un matériau électriquement isolant.Ce brevet FR 69.16.548 décrit des lampes de poche uniquement prévues pour des piles cylindriques et de plus comportant deux fiches métalliques 7 et 9 et un dispositif interrupteur muni d'une lame en contact avec lepôle de la pile opposé au plot de ladite pile cylindrique et venant en contact avec l'une des fiches.There are also known flashlights such as those described in patent FR 69.16.548, which comprise a piece in one piece intended for fixing the lighting head as well as for housing the bulb, said piece being made of an electrically insulating material. This patent FR 69.16.548 describes flashlights only intended for cylindrical batteries and moreover comprising two metal plugs 7 and 9 and a switch device provided with a blade in contact with the pole. of the stack opposite the stud of said cylindrical stack and coming into contact with one of the plugs.

Les lampes de poche selon le brevet français cité ont un montage complexe et sont donc onéreuses à fabriquer.Flashlights according to the cited French patent have a complex assembly and are therefore expensive to manufacture.

Le boîtier suivant l'invention permet d'- éviter tous les inconvénients exposés ci-dessus en limitant à une le nombre de pièces métalliques entrant dans sa réalisation, laquelle pièce,éventuellement, peut être facilement remplacée en cas de détérioration.The housing according to the invention makes it possible to avoid all of the drawbacks set out above by limiting the number of metal parts entering into its production to one, which part, possibly, can be easily replaced in the event of deterioration.

Le boîtier objet de l'invention est constitué principalement d'un corps inférieur et d'un corps supérieur en matière plastique s'assemblant par clipsage élastique. Le corps supérieur comporte le réflecteur parabolique et le verre ainsi qu'une bague épaulée démontable réalisée en matière plastique moulée sur une douille métallique comportant,obtenus par repoussage,des filets dans lesquels se visse l'ampoule électrique, laquelle douille métallique comporte à sa base une lame métallique flexible destinée à réaliser le contact avec le pôle de la pile. Le corps inférieurde section rectangulaire,comporte,en partie haute de l'une de ses petites faces, une rainure débouchante dans le plan de joint des corps supérieur et inférieur dans laquelle se déplace en translation l'axe d'un bouton poussoir, lequel commande le déplacement vertical alterné d'un berceau supportant la pile de façon à mettre en contact les bornes de celle-ci avec la lame métallique de la douille et du culot de la lampe pour fermer le circuit électrique.The housing object of the invention consists mainly of a lower body and an upper body of plastic material assembled by elastic clipping. The upper body comprises the parabolic reflector and the glass as well as a removable shouldered ring made of plastic molded on a metal socket comprising, obtained by pushing back, threads in which the electric bulb is screwed, which metal socket has at its base a flexible metal blade intended to make contact with the pole of the battery. The lower body of rectangular section, comprises, in the upper part of one of its small faces, a through groove in the joint plane of the upper and lower bodies in which the axis of a push button moves in translation, which controls the alternating vertical displacement of a cradle supporting the battery so as to bring the terminals of the latter into contact with the metal blade of the socket and of the lamp base to close the electrical circuit.

The accompanying drawings illustrate, by way of example, a preferred embodiment of the housing according to the present invention. These represent:
  • - Fig. 1, a sectional elevation view along AA of the housing.
  • - Fig. 2, a cross section along BB,
  • - Fig. 3, an end view on the pusher side,
  • - Fig. 4, an end view on the pusher side, the latter being assumed to be removed.

Tel qu'il est représenté,le boîtier est constitué d'un corps inférieur 1 et d'un corps supérieur 2 s'assemblant par clipsage selon un joint horizontal. Le corps supérieur comporte en partie haute un renflement hémisphérique dans lequel s'- encastre un réflecteur parabolique 3 maintenu en position par la mise en place du verre 4 dans l'- embrèvement que forment les bords du renflement hémisphérique,réalisant par l'élasticité du matériau un sertissage de l'assemblage. Le réflecteur 3 porte en son centre un alésage dans lequel s'ajuste à force une bague épaulée 5 réalisée en matière plastique moulée sur une douille métallique 6 comportant, obtenus par repoussage, des filets dans lesquels se visse l'ampoule 7. La base de la douille 6 comporte une lame métallique flexible 8 destinée à réaliser le contact avec le pôle de la pile.As shown, the housing consists of a lower body 1 and an upper body 2 which are assembled by clipping along a horizontal joint. The upper body has in the upper part a hemispherical bulge in which is embedded a parabolic reflector 3 held in position by the positioning of the glass 4 in the recess formed by the edges of the hemispherical bulge, achieving by the elasticity of the material a crimp of the assembly. The reflector 3 carries in its center a bore in which a forced ring 5 made of plastic material molded onto a metal socket 6 having, obtained by pushing back, threads into which the bulb 7 is screwed in. the socket 6 comprises a flexible metal blade 8 intended to make contact with the pole of the battery.

Le corps inférieur 2,de section rectangulaire,comporte,en partie haute de l'une de ses petites faces, une rainure 9 débouchant dans le plan jointif des corps supérieur et inférieur dans laquelle se déplace en translation l'axe 10 d'un bouton poussoir 11 commandant le déplacement vertical alterné d'un berceau 12 soutenant latéralement et par dessus et en dessous la pile 13, de façon à mettre ou non en contact les bornes de celle-ci avec la lame métallique 8 de la douille 6 et avec le culot de l'ampoule 7. Les flancs latéraux du berceau sont inclinés pour situer la traverse inférieure sous la partie milieu de la pile, la retenue supérieure se limitant à quelques millimètres de recouvrement du bord transversal de la pile de façon à ne pas interférer avec l'une des bornes de celle-ci. L'immobilisation du poussoir 11 en position "allumée" ou "éteinte" est réalisée par la découpe de la rainure 9, laquelle découpe est composée de deux orifices circulaires sécants 9a et 9b, débouchant sur le plan jointif des corps supérieur et inférieur par une rainure à bords parallèles 9c. Le diamètre des orifices 9a et 9b d'une part et la largeur de la rainure 9c et de l'étranglement 9d créé par l'intersection desdits orifices d'autre part correspondent respectivement,aux jeux fonctionnels près, aux diamètres étagés 10a et lOb de l'axe 10 du bouton poussoir.L'alternance de ces diamètres pour permettre la translation dudit bouton poussoir est obtenue par pression selon la flèche F, provoquant une translation de l'axe du poussoir dans cette direction, la mise en regard du diamètre 10b avec l'épaisseur du boîtier étant rendue possible par l'élasticité des ailes du bouton poussoir dont les extrémités recourbées sont en appui permanent sur la face externe du boîtier. Le guidage vertical en translation du bouton poussoir est obtenu au moyen de deux nervures 14 encadrant latéralement ledit bouton poussoir.The lower body 2, of rectangular section, comprises, in the upper part of one of its small faces, a groove 9 opening into the contiguous plane of the upper and lower body in which the axis 10 of a button moves in translation. pusher 11 controlling the alternating vertical movement of a cradle 12 supporting laterally and above and below the stack 13, so as to put or not in contact the terminals thereof with the metal blade 8 of the socket 6 and with the base of the bulb 7. The lateral sides of the cradle are inclined to locate the lower cross member under the middle part of the stack, the retainer upper limit is limited to a few millimeters of overlap of the transverse edge of the stack so as not to interfere with one of the terminals thereof. Immobilization of the pusher 11 in the "on" or "off" position is achieved by cutting the groove 9, which cut is made up of two intersecting circular orifices 9a and 9b, opening onto the joined plane of the upper and lower bodies by a parallel edge groove 9c. The diameter of the orifices 9a and 9b on the one hand and the width of the groove 9c and of the constriction 9d created by the intersection of said orifices on the other hand correspond respectively, apart from the functional clearances, to the stepped diameters 10a and 10b of the axis 10 of the push button. The alternation of these diameters to allow the translation of said push button is obtained by pressing along arrow F, causing a translation of the axis of the push button in this direction, the comparison of the diameter 10b with the thickness of the housing being made possible by the elasticity of the wings of the push button, the curved ends of which are in permanent support on the external face of the housing. The vertical guide in translation of the push button is obtained by means of two ribs 14 laterally framing said push button.

L'invention ne se limite aucunement au mode de réalisation spécialement décrit, mais elle embrasse au contraire toutes les variantes possibles à condition que celles-ci ne soient pas en contradiction avec l'objet de chacune des revendications annexées à la présente description.The invention is in no way limited to the embodiment especially described, but it em on the contrary brews all possible variants provided that these are not inconsistent with the subject of each of the claims appended to this description.

C'est ainsi que la bague épaulée peut comporter, exécutés dans le matériau qui la constitue,les filets dans lesquels se visse l'ampoule, la lame métallique flexible 8 étant alors seule incorporée à la bague de façon telle que son extrémité puisse venir en contact avec la douille après vissage de celle-ci.Thus, the shouldered ring may comprise, executed in the material which constitutes it, the threads in which the bulb is screwed, the flexible metal blade 8 then being alone incorporated into the ring so that its end can come in contact with the socket after screwing it.

L'invention s'applique à la réalisation de tous boîtiers de lampe de poche électriques.The invention applies to the production of all electric flashlight housings.
