Description

Domaine technique de l'inventionTechnical field of the invention

L'invention est relative à une lampe électrique portative à boîtier monté angulairement déplaçable, et en particulier à une lampe électrique portative frontale utilisée en alpinisme.The invention relates to a portable electric lamp housing mounted angularly displaceable, and in particular to a frontal portable electric lamp used in mountaineering.

État de la techniqueState of the art

Actuellement, on utilise des lampes électriques portatives à boîtier compact comprenant un module d'éclairage renfermant, par exemple, des diodes électroluminescentes (LED). Généralement, la lampe comporte un support muni d'une sangle permettant de porter la lampe sur la tête. Certaines lampes, comme par exemple celles décrites dans la demande de brevet européen EP 1965129 , ont leur boîtier qui est monté angulairement déplaçable sur le support, autour d'un axe de rotation, de façon à pouvoir orienter l'éclairage en fonction de la distance des objets à éclairer. En outre ces lampes sont pourvues d'ergots pour coopérer avec des crans d'ajustement montés sur le boîtier afin de maintenir le module d'éclairage dans différentes positions. Mais ces systèmes de crans ont tendance à s'user à l'usage. En outre, ces systèmes de crans sont bruyants et peuvent gêner l'utilisateur lorsqu'il souhaite se déplacer discrètement.Currently, compact portable portable lamps are used comprising a lighting module containing, for example, light emitting diodes (LEDs). Generally, the lamp comprises a support provided with a strap for carrying the lamp on the head. Some lamps, such as those described in the European patent application EP 1965129 have their housing which is mounted angularly displaceable on the support, around an axis of rotation, so as to be able to orient the lighting according to the distance of the objects to be illuminated. In addition these lamps are provided with pins to cooperate with adjustment notches mounted on the housing to maintain the lighting module in different positions. But these notches systems tend to wear out with use. In addition, these notches systems are noisy and can hinder the user when he wants to move discreetly.

D'autres lampes, comme par exemple celles décrites dans la demande de brevet européen EP 2251586 , peuvent comporter un support ayant deux extrémités annulaires en saillie pour loger respectivement les deux extrémités du boîtier. Ces extrémités annulaires comprennent également des crans d'ajustement pour maintenir le boîtier en position. Mais ces extrémités annulaires sont encombrantes.Other lamps, such as those described in the European patent application EP 2251586 may comprise a support having two projecting annular ends for respectively housing the two ends of the housing. These annular ends also include Adjustment notches to hold the housing in position. But these annular ends are bulky.

On peut citer par exemple le brevet américain US 1352708 qui divulgue une lampe électrique comprenant un support angulaire sur lequel la lampe est solidement fixée à l'aide de ressorts. Le support angulaire est monté sur une tête sphérique qui peut être animée en rotation pour amener la lampe dans diverses positions selon le point désiré à éclairer. Mais cette lampe est encombrante et sensible à l'usure.For example, the American patent US 1352708 which discloses an electric lamp comprising an angular support on which the lamp is securely fixed by means of springs. The angular support is mounted on a spherical head which can be rotated to bring the lamp into various positions according to the desired point to be illuminated. But this lamp is bulky and sensitive to wear.

Objet de l'inventionObject of the invention

L'objet de l'invention consiste à remédier à ces inconvénients, et à réaliser une lampe électrique portative pourvue d'un moyen d'orientation du module d'éclairage robuste et suffisamment compact.The object of the invention is to overcome these disadvantages, and to achieve a portable electric lamp provided with a means of orientation of the robust and sufficiently compact lighting module.

Selon un aspect de l'invention, il est proposé une lampe électrique portative, caractérisée en ce qu'elle comporte au moins une pièce ayant une forme globalement filaire et comprenant une partie en forme de collier entourant le boîtier autour de l'axe de rotation, ladite pièce étant déformable par élasticité pour maintenir par frottement le boîtier en le maintenant par frottement contre le support dans une position angulaire déterminée.According to one aspect of the invention, there is provided a portable electric lamp, characterized in that it comprises at least one piece having a generally wire-like shape and comprising a collar-shaped portion surrounding the housing around the axis of rotation said part being elastically deformable to frictionally maintain the housing by frictionally holding it against the support in a predetermined angular position.

Ainsi, on offre une lampe dont le module d'éclairage est orientable à l'aide d'une pièce qui est peu encombrante et peu sensible à l'usure. En outre, la pièce est intégrée au boîtier de manière à former un ensemble particulièrement compact. Par ailleurs, la forme de collier d'une partie de la pièce assure un maintien efficace du boîtier contre le support. Une telle lampe permet d'orienter le module d'éclairage selon un nombre de positions angulaires qui est supérieur à celui proposé par les lampes de l'art antérieur.Thus, there is provided a lamp whose lighting module is adjustable with a piece that is compact and insensitive to wear. In addition, the part is integrated into the housing so as to form a particularly compact assembly. Furthermore, the collar shape of a part of the part ensures an effective maintenance of the housing against the support. Such a lamp makes it possible to orient the lighting module according to a number of angular positions which is greater than that proposed by the lamps of the prior art.

Notamment, l'absence de crans d'ajustement offre une rotation du module d'éclairage qui est discret.In particular, the absence of adjustment notches provides a rotation of the lighting module which is discreet.

L'élasticité de la pièce facilite le déplacement angulaire du boîtier. Ainsi, lorsqu'une pièce subit une déformation elle permet une rotation du boîtier, et lorsque la pièce tend à reprendre sa forme elle assure un maintien du boîtier en position par rapport au support.The elasticity of the part facilitates the angular displacement of the housing. Thus, when a part undergoes a deformation it allows a rotation of the housing, and when the part tends to return to its shape it ensures a maintenance of the housing in position relative to the support.

La pièce peut être un ressort de flexion exerçant une force de rappel apte à maintenir par frottement le boîtier contre le support.The part may be a bending spring exerting a restoring force able to frictionally hold the housing against the support.

Le boîtier peut comporter une partie cylindrique entourée par la partie en forme de collier de chaque pièce.The housing may include a cylindrical portion surrounded by the collar portion of each piece.

Ladite pièce peut être de nature métallique pour, notamment, renforcer les propriétés de maintien en position du boîtier et offrir une déformation élastique durable.Said part may be of a metallic nature, in particular to reinforce the properties of maintaining the housing in position and to provide a durable elastic deformation.

Le support peut comporter au moins un ergot coopérant avec des crans d'ajustement montés sur le boîtier pour assurer un réglage indexé angulaire du boîtier.The support may comprise at least one lug cooperating with adjustment notches mounted on the housing to provide an angular indexed adjustment of the housing.

Ainsi, on renforce le maintien en position du boîtier par rapport au support.Thus, it reinforces the holding position of the housing relative to the support.

Description détailléedetailed description

Sur la figure 1, on a représenté de façon schématique une lampe électrique portative 1 comportant un boîtier compact 2 renfermant un module d'éclairage 3 muni d'une LED, de préférence une LED de puissance. Le module d'éclairage 3 peut également comporter plusieurs LED, de puissance ou standards. Le boîtier 2 peut comporter en outre un compartiment pour loger une source d'alimentation, non représentée ici à des fins de simplification. La source d'alimentation est formée par une batterie ou des piles, et est configurée pour alimenter le module d'éclairage 3. Selon un autre mode de réalisation, la source d'alimentation est logée dans un compartiment extérieur au boîtier 2 et est couplée au module d'éclairage 3 par l'intermédiaire d'une connexion électrique filaire. La lampe électrique portative 1 peut être une lampe frontale, ou une lampe torche, et le boîtier 2 peut être réalisé en matériau isolant ou métallique.On the figure 1 , schematically shows a portable electric lamp 1 having a compact housing 2 enclosing a lighting module 3 provided with an LED, preferably a power LED. The lighting module 3 may also include several LEDs, power or standards. The housing 2 may further include a compartment for housing a power source, not shown here for simplification purposes. The power source is formed by a battery or batteries, and is configured to power the lighting module 3. According to another embodiment, the power source is housed in a compartment outside the housing 2 and is coupled to the lighting module 3 via a wired electrical connection. The portable electric lamp 1 may be a headlamp, or a flashlight, and the housing 2 may be made of insulating or metallic material.

La lampe 1 comporte un support 4 sur lequel le boîtier 2 est monté angulairement déplaçable autour d'un axe de rotation 5 correspondant à un axe longitudinal de la lampe 1. On peut ainsi déplacer le boîtier 2 entre une position haute et une position basse pour modifier l'orientation de l'éclairage de la LED. Dans la position haute, on favorise l'éclairage des objets éloignés et dans une position basse, on favorise celui des objets proches. Le boîtier 2 a un corps ayant une partie cylindrique 6 destinée à être en appui contre le support 4, et s'étendant le long de l'axe de rotation 5. Un actionneur de commande 7 est prévu à une extrémité du corps du boîtier 2 pour commander l'éclairage, et l'extinction, de la lampe 1. La lampe 1 peut également comporter un actionneur additionnel de commande 8, situé sur une face supérieure du corps du boîtier 2, afin de sélectionner l'activation d'une LED parmi les LED du module d'éclairage 3. Avantageusement, le module d'éclairage 3 peut être monté mobile en rotation autour d'un axe transversal 9 sensiblement perpendiculaire à l'axe longitudinal 5. Par ailleurs, la lampe 1 comprend au moins une pièce additionnelle 10, 11 pour maintenir le boîtier 2, et en particulier la partie cylindrique 6, selon une position angulaire déterminée par rapport au support 4. Dans l'exemple illustré aux figures 1 et 2a, la lampe 1 comporte deux pièces additionnelles 10, 11, et on peut également envisager de munir la lampe 1 de plusieurs pièces additionnelles.The lamp 1 comprises a support 4 on which the housing 2 is mounted angularly displaceable about an axis of rotation corresponding to a longitudinal axis of the lamp 1. It is thus possible to move the housing 2 between a high position and a low position for change the orientation of the lighting of the LED. In the high position, we favor the lighting of distant objects and in a low position, we favor that of nearby objects. The housing 2 has a body having a cylindrical portion 6 intended to bear against the support 4, and extending along the axis of rotation 5. A control actuator 7 is provided at one end of the body of the housing 2 to control the lighting, and extinguishing, of the lamp 1. The lamp 1 may also include an additional control actuator 8, located on an upper face of the body of the housing 2, to select the activation of an LED 3. Advantageously, the lighting module 3 can be rotatably mounted about a transverse axis 9 substantially perpendicular to the longitudinal axis 5. Furthermore, the lamp 1 comprises at least one additional piece 10, 11 for holding the housing 2, and in particular the cylindrical portion 6, in a predetermined angular position relative to the support 4. In the example illustrated in FIGS. Figures 1 and 2a the lamp 1 comprises two additional pieces 10, 11, and it is also conceivable to provide the lamp 1 with several additional pieces.

De manière générale, chaque pièce additionnelle 10, 11 a une partie 12, 13 en forme de collier ouvert, en particulier en forme de C, qui entoure la partie cylindrique 6 du boîtier 2. Chaque pièce 10, 11 comprend deux extrémités 14 à 17 en vis-à-vis l'une de l'autre et formant l'ouverture 18, 19 de la partie 12, 13 en forme de collier. Les extrémités 14 à 17 sont montées fixes sur le support 4, par exemple elles sont logées respectivement dans des cavités 20 à 23 prévues dans le support 4. Chaque ouverture 18, 19 formée entre deux extrémités d'une pièce 10, 11 permet un contact entre le corps cylindrique 6 et le support 4. En d'autres termes, la partie 12, 13 en forme de collier s'étend autour de l'axe longitudinal 5 de façon à permettre un déplacement angulaire de la partie cylindrique 6 du boîtier 2. Avantageusement, chaque pièce additionnelle 10, 11 est réalisée en matière élastique, par exemple en matière plastique ou métallique, comportant un effet ressort pour tolérer une déformation permettant d'une part de faciliter la rotation du boîtier 2 lorsqu'il est déformé, et d'autre part de renforcer le maintien du boîtier 2 en position lorsqu'il tend à reprendre sa forme initiale. Ainsi, le boîtier 2 est maintenu selon une position angulaire déterminée, par un frottement du boîtier 2 contre le support 4, afin de garantir un éclairage selon une direction constante souhaitée par l'utilisateur. L'effet ressort de la pièce 10, 11 empêche une rotation complète du boîtier 2, c'est-à-dire une rotation sans aucune retenue. Par ailleurs, la partie cylindrique 6 du boîtier 2 permet d'obtenir plusieurs orientations possibles pour le module d'éclairage 3. Lors du montage de la pièce additionnelle 10, 11, les extrémités 14, 15 d'une pièce 10 sont logées dans les cavités 20, 21 respectives et la pièce 10 adopte une forme initiale sans contrainte. Puis, la partie cylindrique 6 du boîtier 2 est insérée dans chaque partie 12, 13 en forme de collier de sorte que chaque pièce additionnelle 10, 11 est déformée, en d'autres termes mise en contrainte. La mise en contrainte des extrémités 14, 15 permet de plaquer le boîtier 2 contre le support 4, pour le maintenir dans une position angulaire déterminée, notamment par les forces de frottement générées. Ainsi, la partie 12, 13 en forme de collier de chaque pièce 10, 11 est au contact de la partie cylindrique 6 et génère une force de frottement qui participe avec les forces de réaction générées par les extrémités 14 à 17 pour maintenir efficacement le boîtier 2 dans une position angulaire déterminée. La pièce additionnelle 10, 11 réalise une fonction charnière permettant le réglage de l'orientation du module d'éclairage 4. Avantageusement, chaque pièce 10, 11 est une pièce distincte du boîtier 2 et du support 4, de façon à obtenir des éléments qui sont simples à fabriquer et à assembler.In general, each additional piece 10, 11 has a portion 12, 13 in the form of an open collar, in particular C-shaped, which surrounds the cylindrical portion 6 of the housing 2. Each part 10, 11 comprises two ends 14 to 17 facing each other and forming the opening 18, 19 of the portion 12, 13 in the form of a collar. The ends 14 to 17 are mounted fixed on the support 4, for example they are respectively housed in cavities 20 to 23 provided in the support 4. Each opening 18, 19 formed between two ends of a part 10, 11 allows a contact between the cylindrical body 6 and the support 4. In other words, the portion 12, 13 in the form of collar extends around the longitudinal axis 5 so as to allow angular displacement of the cylindrical portion 6 of the housing 2 Advantageously, each additional piece 10, 11 is made of an elastic material, for example a plastic or metal material, comprising a spring effect to tolerate a deformation on the one hand to facilitate the rotation of the housing 2 when it is deformed, and on the other hand to strengthen the maintenance of the housing 2 in position when it tends to resume its original shape. Thus, the housing 2 is held in a predetermined angular position, by friction of the housing 2 against the support 4, to ensure illumination in a constant direction desired by the user. The spring effect of the piece 10, 11 prevents a complete rotation of the housing 2, that is to say a rotation without any restraint. Moreover, the cylindrical portion 6 of the housing 2 makes it possible to obtain several possible orientations for the lighting module 3. During the assembly of the additional part 10, 11, the ends 14, 15 of a part 10 are housed in the cavities 20, 21 respectively and the piece 10 adopts an initial form without constraint. Then, the cylindrical portion 6 of the housing 2 is inserted into each portion 12, 13 in the form of a collar so that each additional piece 10, 11 is deformed, in other words stressed. The stressing of the ends 14, 15 makes it possible to press the housing 2 against the support 4, to maintain it in a determined angular position, in particular by the friction forces generated. Thus, the collar portion 12, 13 of each piece 10, 11 is in contact with the cylindrical portion 6 and generates a friction force which participates with the reaction forces generated by the ends 14 to 17 to effectively maintain the housing 2 in a determined angular position. The additional piece 10, 11 performs a hinge function for adjusting the orientation of the lighting module 4. Advantageously, each piece 10, 11 is a separate piece of the housing 2 and the support 4, so as to obtain elements that are simple to manufacture and assemble.

Selon un mode de réalisation illustré à la figure 2a, la lampe 1 comporte deux pièces additionnelles 10, 11. Chaque pièce 10, 11 est un fil métallique plié à propriété élastique. Dans ce cas, chaque pièce 10, 11 comporte deux extrémités 14 à 17 destinées à être montées fixes sur le support 4 et comporte une partie 12, 13 en forme de C destinée à être enroulée autour de la partie cylindrique 6 du boîtier 2.According to an embodiment illustrated in figure 2a the lamp 1 comprises two additional pieces 10, 11. Each piece 10, 11 is a folded wire with elastic property. In this case, each piece 10, 11 has two ends 14 to 17 intended to be fixedly mounted on the support 4 and has a C-shaped portion 12, 13 to be wound around the cylindrical portion 6 of the housing 2.

Selon un mode de réalisation préféré, illustré à la figure 2b, on réalise une unique pièce additionnelle 10 qui peut comporter une ou plusieurs parties 12, 13 en forme de C entourant le boîtier 2. La pièce 10 est un fil métallique plié à propriété élastique pour former deux parties 12, 13 en forme de collier ouvert. Les deux parties 12, 13 de la pièce additionnelle 10 sont réunies par au moins deux extrémités opposées 14, 16 ou 15, 17 de manière à former une seule pièce. Le fil métallique offre une meilleure solidité pour obtenir un effet ressort durable.According to a preferred embodiment, illustrated in FIG. figure 2b a single additional piece 10 is made which may comprise one or more C-shaped portions 12, 13 surrounding the casing 2. The piece 10 is a folded wire of elastic property to form two open-necked portions 12, 13 . The two parts 12, 13 of the additional piece 10 are joined by at least two opposite ends 14, 16 or 15, 17 so as to form a single piece. Wire provides greater strength for a durable spring effect.

Sur la figure 3, on a représenté une vue en coupe schématique selon l'axe A-A de la figure 1. On note sur la figure 3 que le support 4 est incliné d'un angle d'environ 45° par rapport à l'axe transversal 9.On the figure 3 , there is shown a schematic sectional view along the axis AA of the figure 1 . We note on the figure 3 that the support 4 is inclined at an angle of approximately 45 ° with respect to the transverse axis 9.

Sur la figure 4, on a illustré schématiquement encore un autre mode de réalisation, dans lequel la lampe 1 comporte, de manière optionnelle, un système d'indexage 24, par exemple un système 24 de crans d'ajustement 25, pour notamment renforcer le maintien du boîtier 2 en position. Dans cet autre mode de réalisation, le support 4 comporte un ergot 26 destiné à coopérer avec les crans d'ajustement 25 montés sur le boîtier 2. Lors de la rotation du boîtier 2, le franchissement des crans génère une force qui tend à déplacer transversalement l'axe de rotation 5 de la lampe 1 en déformant les pièces additionnelles 10, 11. Le déplacement transversal de l'axe de rotation 5 est possible grâce à l'élasticité de chaque pièce 10, 11.On the figure 4 another embodiment is schematically illustrated, in which the lamp 1 optionally comprises an indexing system 24, for example a system 24 of adjustment notches 25, in particular to strengthen the retention of the housing 2 in position. In this other embodiment, the support 4 comprises a lug 26 intended to cooperate with the adjustment notches 25 mounted on the casing 2. During the rotation of the casing 2, the crossing of the catches generates a force which tends to move transversely. the axis of rotation 5 of the lamp 1 by deforming the additional parts 10, 11. The transverse displacement of the axis of rotation 5 is possible thanks to the elasticity of each piece 10, 11.

Ainsi, on offre une lampe électrique portative compacte pourvue d'un système simple et robuste pour permettre de régler l'inclinaison du module d'éclairage tout en assurant son maintien dans une position souhaitée par l'utilisateur. On peut avantageusement régler la rotation du module d'éclairage selon un axe de rotation fixe par rapport au support, en particulier selon un axe longitudinal de la lampe, pour garantir la compacité de celle-ci.Thus, there is provided a compact portable electric lamp with a simple and robust system to allow adjusting the inclination of the lighting module while ensuring its maintenance in a desired position by the user. It is advantageous to adjust the rotation of the module lighting according to a fixed axis of rotation relative to the support, in particular along a longitudinal axis of the lamp, to ensure the compactness thereof.
