Abstract

The supply cable(20) enters the circular base(5) via a safety switch(24). An on/off switch(23) controls its connection to the lamp cable(3). This runs in an adjustably oriented flexible sheath secured by a screwed ferrule(17,21). The base's flexible skirt (5b), radially slit(26), permits conformity with curved supporting surfaces e.g., windscreens. Pressing the base against the selected surface, the user turns a pivoted handle(10) through 90 degree, thus raising a central column, fixed internally on the membrane(6), against a return spring(13) and creating a vacuum which securely holds the base, with the attached lamp. The safety pressure switch(24,24a) interrupts the incoming supply immediately the base separates from the surface.

Description

L'invention concerne le domaine des dispositifs d'éclairage baladeur, également dénommés baladeuses, utilisées pour éclairer temporairement une zone dépourvue de lumière.The invention relates to the field of portable lighting devices, also called portable lamps, used for temporarily lighting an area devoid of light.

La baladeuse traditionnelle, composée d'un manche porte douille et d'une cage entourant l'ampoule disposée dans la douille, se fixe par suspension au moyen d'un crochet dont est munie la cage. Si ce mode de fixation convient pour un travail dans un atelier comportant des éléments en saillie, il est inutilisable lorsqu'il n'y a pas de saillies et par exemple pour fixer la source d'éclairage à l'intérieur d'un véhicule ou sur la carrosserie de ce véhicule.The traditional portable lamp, composed of a socket holder handle and a cage surrounding the bulb placed in the socket, is fixed by suspension by means of a hook with which the cage is fitted. If this method of attachment is suitable for work in a workshop with projecting elements, it cannot be used when there are no projections and for example to fix the light source inside a vehicle or on the body of this vehicle.

Il en est de même pour les dispositifs dans lesquels la source d'éclairage est fixée à l'extrémité d'un flexible dont l'autre extrémité est solidaire d'un socle à fixation magnétique car, à l'intérieur d'une automobile actuelle, il existe peu de paroi acceptant une fixation magnétique et, à l'extérieur, la mise en place de la fixation magnétique peut rayer la carrosserie.The same is true for devices in which the light source is fixed to the end of a hose, the other end of which is secured to a base with magnetic fastening because, inside a current automobile , there is little wall accepting a magnetic fixing and, outside, the installation of the magnetic fixing can scratch the bodywork.

Un autre inconvénient de ces dispositifs à flexibles résulte de la direction de départ du flexible par rapport au socle. En effet, le départ du flexible, perpendiculairement à la face d'appui du socle, se combine avec la raideur du flexible, limitant son rayon de cintrage, pour délimiter une aire de balayage par la source lumineuse qui est inférieure à ce qu'on pourrait obtenir en utilisant le seul flexible. Il en résulte que, même si l'on parvient à fixer le socle sur les zones magnétiques disposées à distance de la zone de travail, il n'est pas possible d'utiliser au mieux le flexible et que l'éclairage obtenu est insuffisant.Another disadvantage of these flexible devices results from the direction of departure of the flexible relative to the base. Indeed, the departure of the hose, perpendicular to the support face of the base, combines with the stiffness of the hose, limiting its bending radius, to delimit a scanning area by the light source which is less than what is could get using the single hose. The result is that, even if it is possible to fix the base on the magnetic zones arranged at a distance from the working zone, it is not possible to make the best use of the hose and that the lighting obtained is insufficient.

Le brevet US-A-4 238 816 décrit une baladeuse qui remédie à ces inconvénients en utilisant une ventouse comme moyen de fixation du socle et en orientant sensiblement radialement le départ du fusible flexible.Patent US-A-4 238 816 describes a portable lamp which overcomes these drawbacks by using a suction cup as a means of fixing the base and by orienting the departure of the flexible fuse substantially radially.

A l'utilisation il s'avère que ce mode de fixation, parfaitement adapté pour des surfaces planes, ne convient pas pour les surfaces galbées, de sorte que cette baladeuse ne peut pas être fixée sur la face interne de vitrages galbés d'un véhicule.In use, it turns out that this method of attachment, perfectly suited for flat surfaces, is not suitable for curved surfaces, so that this portable lamp cannot be fixed on the internal face of curved glazing of a vehicle. .

Un autre inconvénient de la fixation par ventouse provient de sa faculté à se désolidariser du support après un temps plus ou moins long, ce qui peut mettre en contact la source lumineuse ou le capot qui la protège et qui est en général brûlant au toucher, avec des parois telles que revêtement synthétique du tableau de bord ou habillage de siège, pouvant fondre ou s'enflammer, en cas de contact prolongé.Another disadvantage of fixing by suction cup comes from its ability to dissociate from the support after a more or less long time, which can bring the light source or the hood which protects it and which is generally hot to the touch, with walls such as synthetic coating of the dashboard or seat cover, which may melt or ignite in the event of prolonged contact.

La présente invention a pour objet de remédier à ces inconvénients.The object of the present invention is to remedy these drawbacks.

A cet effet, dans le dispositif d'éclairage, selon l'invention, le corps du socle est réalisé dans une matière synthétique semi-rigide, et présente une jupe périphérique élastiquement déformable et apte à épouser une surface d'appui concave ou convexe tout en plaquant le bord de la membrane de la ventouse, par réaction à la traction axiale exercée par le levier, ce corps étant solidaire d'un boîtier transversal qui, recevant les moyens d'alimentation de la source lumineuse et portant son interrupteur de commande, s'étend radialement au delà de la membrane pour supporter un contacteur de sécurité, ouvert au repos et dont le palpeur est apte à venir en contact avec la surface recevant le socle pour fermer le circuit électrique aboutissant à l'interrupteurTo this end, in the lighting device according to the invention, the body of the base is made of a semi-rigid synthetic material, and has an elastically deformable peripheral skirt and capable of marrying a concave or convex bearing surface while in pressing the edge of the diaphragm of the suction cup, by reaction to the axial traction exerted by the lever, this body being integral with a transverse housing which, receiving the means for supplying the light source and carrying its control switch, s 'extends radially beyond the membrane to support a safety contactor, open at rest and whose feeler is able to come into contact with the surface receiving the base to close the electrical circuit leading to the switch

Lors de l'actionnement du levier pour créer une dépression sous la ventouse, la réaction à l'effort de traction axial exercé par le levier plaque la jupe du socle sur la membrane en appui sur la surface et force cette jupe à épouser le profil galbé de cette surface. Cela a pour effet d'améliorer, localement et suivant un cercle, le plaquage de la membrane sur la surface, et d'augmenter l'étanchéité, et, en conséquence, le temps pendant lequel la ventouse peut rester fixée sur la surface, notamment le vitrage.When the lever is actuated to create a vacuum under the suction cup, the reaction to the axial tensile force exerted by the lever presses the skirt of the base on the membrane bearing on the surface and forces this skirt to match the curved profile of this surface. This has the effect of improving, locally and in a circle, the plating of the membrane on the surface, and of increasing the tightness, and, consequently, the time during which the suction cup can remain fixed on the surface, in particular glazing.

Dans le cas où la ventouse perd ses propriétés d'adhérence et provoque la chute du dispositif, le palpeur du contacteur de sécurité perd contact avec le support et ouvre le circuit électrique d'alimentation de la source lumineuse, c'est-à-dire interrompt automatiquement l'alimentation de cette source, en supprimant ainsi tous risques de brûlures ou de départ d'incendie.In the event that the suction cup loses its adhesion properties and causes the device to fall, the safety contactor probe loses contact with the support and opens the electrical circuit supplying the light source, that is to say automatically interrupts the supply of this source, thereby eliminating any risk of burns or fire starting.

Cet agencement permet donc d'utiliser, en toute sécurité, une source lumineuse ayant un fort dégagement calorifique, par exemple, de type halogène.This arrangement therefore makes it possible to use, in complete safety, a light source having a high calorific release, for example, of the halogen type.

D'autres caractéristiques et avantages ressortiront de la description qui suit en référence au dessin schématique annexé représentant une forme d'exécution de ce dispositif d'éclairage.

  • Figure 1 est une vue partielle de côté en élévation montrant le dispositif lorsqu'il est mis en place contre la face interne du pare-brise d'un véhicule,
  • Figure 2 est une vue en plan par dessus, à échelle agrandie, du dispositif seul,
  • Figures 3 et 4 sont des vues en coupe suivant, respectivement III-III et IV-IV de figure 2, lorsque la ventouse est respectivement actionnée et au repos.
Other characteristics and advantages will emerge from the description which follows with reference to the appended schematic drawing representing an embodiment of this lighting device.
  • FIG. 1 is a partial side view in elevation showing the device when it is placed against the internal face of the windshield of a vehicle,
  • FIG. 2 is a plan view from above, on an enlarged scale, of the device alone,
  • Figures 3 and 4 are sectional views along line III-III and IV-IV of Figure 2, respectively, when the suction cup is respectively actuated and at rest.

Dans ce dessin, la référence numérique 2 désigne une source lumineuse disposée à l'extrémité d'un flexible 3 dont l'autre extrémité est solidaire d'un socle de fixation 4.In this drawing, the reference numeral 2 designates a light source disposed at the end of a hose 3, the other end of which is secured to a fixing base 4.

Comme montré plus particulièrement aux figures 2 et 3, ce socle 4 est constitué par le corps d'appui 5 d'un dispositif de fixation à ventouse comportant une membrane circulaire 6, solidaire d'un axe vertical 7 monté coulissant dans un palier 8 du corps 5. Une goupille 9 traversant de part en part l'extrémité supérieure de l'axe 7 assure l'articulation de cet axe avec les deux branches d'une chape 10a, ménagée à l'extrémité d'un levier 10. Les faces 12a et 12b de la chape 10a venant en contact avec le palier 8 sont séparées de l'axe géométrique de la goupille 9 par des distances différentes et un ressort 13 interposé entre la membrane 6 et le fond du corps 5, rappelle constamment l'une de ces faces contre la face supérieure du palier 8.As shown more particularly in FIGS. 2 and 3, this base 4 is constituted by the support body 5 of a suction cup fixing device comprising a circular membrane 6, integral with a vertical axis 7 slidably mounted in a bearing 8 of the body 5. A pin 9 passing right through the upper end of the axis 7 ensures the articulation of this axis with the two branches of a yoke 10a, formed at the end of a lever 10. The faces 12a and 12b of the yoke 10a coming into contact with the bearing 8 are separated from the geometric axis of the pin 9 by different distances and a spring 13 interposed between the membrane 6 and the bottom of the body 5, constantly reminds one of these faces against the upper face of the bearing 8.

On conçoit aisément que, lorsque le levier 10 est redressé à la verticale, avec sa face 12b en contact avec le palier 8, la membrane 6 est libre et vient en contact par toute sa surface avec la face 11 contre laquelle elle est posée, comme montré figure 4, tandis que, lorsque le levier est abaissé, comme montré à la figure 3, avec la face 12a en contact avec le palier, la partie centrale de la membrane 6 est espacée de la surface d'appui 11 en formant un vide qui assure la fixation de la membrane et de la ventouse sur cette face d'appui.It is easily understood that, when the lever 10 is straightened vertically, with its face 12b in contact with the bearing 8, the membrane 6 is free and comes into contact through its entire surface with the face 11 against which it is placed, as shown in Figure 4, while when the lever is lowered, as shown in Figure 3, with the face 12a in contact with the bearing, the central part of the membrane 6 is spaced from the bearing surface 11 by forming a vacuum which ensures the attachment of the membrane and the suction cup on this support face.

Dans la forme d'exécution représentée, le corps d'appui 5 est composé d'un fond 5a et d'une jupe circulaire 5b venant en appui sur le bord périphérique de la membrane 6, mais il est évident qu'il peut présenter toute autre forme géométrique.In the embodiment shown, the support body 5 is composed of a bottom 5a and a circular skirt 5b bearing on the peripheral edge of the membrane 6, but it is obvious that it can have any other geometric shape.

Selon l'invention, ce corps est réalisé dans une matière synthétique semi-rigide élastiquement déformable de manière que sa jupe 5b puisse se déformer pour épouser le galbe, convexe ou concave du support, qu'il s'agisse d'un vitrage ou du garnissage du tableau.According to the invention, this body is made of an elastically deformable semi-rigid synthetic material so that its skirt 5b can be deformed to conform to the curve, convex or concave of the support, whether it is a glazing or a panel filling.

Le corps 5 est solidaire d'un boîtier 14 qui, disposé transversalement, est parallèle au plan diamétral confondu avec le plan médian du levier 10. L'une des extrémités de ce boîtier, et par exemple celle 15 à la figure 4, sert à la fixation du flexible 3. A cet effet, le palier est traversé par un alésage 16 servant au passage d'une tige de fixation creuse 17, solidaire du flexible 3. L'extrémité libre de cette tige pénètre dans un puits 18 juxtaposé au palier 15 et ménagé dans le boîtier 14. Ce puits est utilisé pour la mise en place d'un écrou 21 de fixation et pour le passage du circuit d'alimentation 19 de la source lumineuse 2.The body 5 is integral with a housing 14 which, arranged transversely, is parallel to the diametral plane coinciding with the median plane of the lever 10. One of the ends of this housing, and for example that 15 in FIG. 4, serves to the fixing of the flexible 3. For this purpose, the bearing is crossed by a bore 16 serving for the passage of a hollow fixing rod 17, integral with the flexible 3. The free end of this rod enters a well 18 juxtaposed with the bearing 15 and formed in the housing 14. This well is used for the installation of a nut 21 for fixing and for the passage of the supply circuit 19 of the light source 2.

La forme d'exécution représentée correspondant à un dispositif d'éclairage à alimentation par le secteur, le cordon d'alimentation 20, muni à son extrémité libre de la fiche de connexion en réseau, non représentée, pénètre dans le boîtier 14 par l'extrémité de ce boîtier qui est opposée à celle liée au flexible 3. Les conducteurs isolés 22 du cordon sont connectés à l'interrupteur 23, lui-même raccordé au circuit d'alimentation 19.The embodiment shown corresponding to a mains-powered lighting device, the power cord 20, provided at its free end with the network connection plug, not shown, enters the housing 14 through the end of this box which is opposite to that linked to the flexible 3. The insulated conductors 22 of the cord are connected to the switch 23, itself connected to the supply circuit 19.

La liaison entre le cordon 20 et les conducteurs 22 est assurée par l'intermédiaire d'un contacteur de sécurité 24, disposé dans le boîtier 14, et muni d'un palpeur 24a faisant saillie vers le bas, au-delà de la membrane 6, dont il est espacé radialement. Dans sa position de repos, montrée à la figure 4, le contacteur 24 ouvre le circuit électrique et empêche toute alimentation de la source lumineuse 2. Par contre, lorsque le dispositif est posé sur une surface, le recul du palpeur 24a dans son boîtier ferme le circuit et permet cette alimentation. Cet agencement évite donc toute alimentation du dispositif, lorsqu'il n'est pas posé sur une surface et interrompt donc cette alimentation en cas de chute du dispositif par décollement de la ventouse.The connection between the cord 20 and the conductors 22 is ensured by means of a safety contactor 24, disposed in the housing 14, and provided with a probe 24a projecting downward, beyond the membrane 6 , from which it is radially spaced. In its rest position, shown in FIG. 4, the contactor 24 opens the electrical circuit and prevents any supply of the light source 2. On the other hand, when the device is placed on a surface, the recoil of the probe 24a in its closed housing the circuit and allows this supply. This arrangement therefore avoids any supply of the device, when it is not placed on a surface and therefore interrupts this supply in case of fall of the device by detachment of the suction cup.

La figure 1 montre que ce dispositif peut être fixé sur toute surface lisse et, par exemple sur la face interne du vitrage avant d'un véhicule pour éclairer une zone de travail sur le tableau de bord de ce véhicule. Grâce à la jupe élastiquement déformable 5b qui, pour des galbes courants, se déforme en prenant appui sur la membrane par une portée sensiblement circulaire, l'étanchéité entre l'extérieur et la partie interne de la ventouse est améliorée et la durée de fixation est augmentée.Figure 1 shows that this device can be fixed on any smooth surface and, for example on the internal face of the front glazing of a vehicle to illuminate a work area on the dashboard of this vehicle. Thanks to the elastically deformable skirt 5b which, for common curves, is deformed by bearing on the membrane by a substantially circular bearing, the seal between the outside and the internal part of the suction cup is improved and the duration of fixing is increased.

La déformabilité du socle est augmentée en réalisant dans son corps 5 des fentes radiales 26, espacées angulairement les unes des autres. Ces fentes s'étendent depuis la jupe 5b jusque dans le fond 5a du socle. Comme représenté, ces fentes peuvent ne pas déboucher de la jupe, ou au contraire déboucher de celle ci, pour augmenter la déformabilité du socle et lui permettre d'épouser des surfaces plus galbées, concaves ou convexes.The deformability of the base is increased by producing in its body 5 radial slots 26, angularly spaced from one another. These slots extend from the skirt 5b to the bottom 5a of the base. As shown, these slots may not open out of the skirt, or on the contrary open out of the latter, to increase the deformability of the base and allow it to marry more curved, concave or convex surfaces.

Il ressort de ce qui précède que le dispositif selon l'invention est simple et peu onéreux à réaliser, peut être fixé sur toute surface lisse, magnétique ou non, plane, concave ou convexe, à l'intérieur ou à l'extérieur du véhicule, mais aussi sur toute autre surface juxtaposée à une zone nécessitant une réparation et un entretien. La fixation par ventouse ne procure aucune détérioration de la surface contre laquelle elle est apposée, ce qui permet de fixer le dispositif, même sur des surfaces fragiles ou dont la réparation est onéreuse.It appears from the above that the device according to the invention is simple and inexpensive to produce, can be fixed to any smooth surface, magnetic or not, flat, concave or convex, inside or outside the vehicle , but also on any other surface adjacent to an area requiring repair and maintenance. The suction cup fixing does not cause any deterioration of the surface against which it is affixed, which makes it possible to fix the device, even on fragile surfaces or whose repair is expensive.

Il est évident que l'invention ne se limite pas à la forme d'exécution du dispositif qui a été décrit ci-dessus, tant en ce qui concerne la forme de la ventouse, le nombre de ventouses utilisées, la nature de la source lumineuse et les moyens assurant son alimentation, ces moyens pouvant être non seulement le réseau, mais aussi le circuit électrique 12 volts du véhicule, et voire même une pile intégrée au dispositif.It is obvious that the invention is not limited to the embodiment of the device which has been described above, both with regard to the shape of the suction cup, the number of suction cups used, the nature of the light source. and the means ensuring its supply, these means being able to be not only the network, but also the 12-volt electric circuit of the vehicle, and even even a battery integrated into the device.
