Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne le domaine des lampes électriques portatives et notamment une lampe frontale dotée d'un bandeau rigide ou semi-rigide.The present invention relates to the field of portable electric lamps and in particular a headlamp with a rigid or semi-rigid headband.

Etat de la techniqueState of the art

Les lampes frontales, utilisées à l'origine par les mineurs, connaissent un grand développement notamment dans le domaine des loisirs, et notamment la spéléologie et la randonnée.Headlamps, originally used by minors, are experiencing a great development especially in the field of recreation, including caving and hiking.

Elles sont par ailleurs utilisées largement dans le domaine professionnel et ont vocation à trouver de multiples nouvelles applications.They are also widely used in the professional field and are intended to find many new applications.

Comme le rappelle la figure 1 illustrant une lampe frontale conventionnelle, une lampe 10 est, le plus souvent, associée à un bandeau élastique 11 permettant de maintenir la lampe sur la tête de l'utilisateur avec un confort maximum.As recalled by figure 1 illustrating a conventional headlamp, a lamp 10 is, most often, associated with an elastic headband 11 for holding the lamp on the head of the user with maximum comfort.

Une telle lampe présente toutefois l'inconvénient d'être inadaptée à servir de source de lumière dans d'autres circonstances que celles pour lesquelles elle a été conçue initialement. En particulier, lorsque l'utilisateur bivouaque et partage son repas avec un autre utilisateur, l'utilisation de la lampe frontale 10 est inappropriée car susceptible d'éclairer, et même d'éblouir, le convive qui partage son repas avec l'utilisateur.Such a lamp, however, has the disadvantage of being unsuited to serve as a light source in circumstances other than those for which it was originally designed. In particular, when the user bivouacs and shares his meal with another user, the use of the headlamp 10 is inappropriate because it may illuminate, and even dazzle, the guest who shares his meal with the user.

Dans une situation, qui n'est qu'un exemple parmi d'autres, la lampe frontale ne permet pas un usage aussi pratique et convivial qu'elle pourrait le permettre.In a situation, which is only one example among others, the headlamp does not allow a use as practical and user-friendly as it could allow.

La présente invention a pour but de remédier à cette situation.The present invention aims to remedy this situation.

Le document US 2007/177376 décrit une lampe portable portée autour du cou et comportant un axe pivot permettant une rotation de la lampe entre une première et une seconde amplitude.The document US 2007/177376 discloses a portable lamp carried around the neck and having a pivot axis for a rotation of the lamp between a first and a second amplitude.

Exposé de l'inventionPresentation of the invention

La présente invention a pour but de proposer une lampe frontale présentant une ergonomie améliorée...The present invention aims to provide a headlamp with improved ergonomics ...

Un autre but de la présente invention consiste à proposer une lampe frontale permettant une utilisation pratique en « tour de cou » offrant un second mode d'utilisation particulièrement commode en d'autres situations que les situations conventionnelles des lampes frontales.Another object of the present invention is to provide a headlamp for practical use in "chokers" offering a second mode of use particularly convenient in other situations than the conventional situations of headlamps.

C'est un autre but de la présente invention que de fournir un lampe frontale permettant un réglage aisé du faisceau lumineux pour diverses utilisations, notamment lors de l'utilisation en tour de cou, voire lorsque la lampe est tout simplement accrochée à un support, telle qu'une branche d'arbre.It is another object of the present invention to provide a headlamp for easy adjustment of the light beam for various uses, especially when used in the neck, or when the lamp is simply attached to a support, such as a tree branch.

L'invention réalise ces buts au moyen d'une lampe frontale comportant une lampe et un bandeau permettant le maintien de la lampe frontale sur la tête d'un utilisateur, le bandeau comportant une partie avant rigide/semi-rigide servant de support à une lampe. La lampe est dotée d'au moins un pivot permettant de pivoter sur ladite partie avant dudit bandeau, et configurée pour permettre une rotation ayant :

  • une première amplitude d'au moins 0 à +30 degrés, et de préférence 0 à 45 degrés, pour assurer un éclairage approprié lorsque la lampe est portée de manière conventionnelle autour de la tête ;
  • une seconde amplitude allant d'au moins 0 à -45° degrés, et de préférence 0 à -80 degrés, pour assurer un éclairage approprié lorsque la lampe est portée autour du cou sans être renversée ;
avec l'inclinaison 0° correspondant au pivot de la lampe générant un faisceau lumineux horizontal lorsque la lampe frontale est positionnée sur la tête d'un utilisateur se tenant debout, les yeux fixant l'horizon.The invention achieves these goals by means of a headlamp comprising a lamp and a headband for holding the headlamp on the head of a user, the headband having a rigid / semi-rigid front portion serving as a support for a lamp. The lamp is provided with at least one pivot for pivoting on said front portion of said strip, and configured to allow rotation having:
  • a first amplitude of at least 0 to + 30 degrees, and preferably 0 to 45 degrees, to provide adequate illumination when the lamp is conventionally carried around the head;
  • a second amplitude ranging from at least 0 to -45 ° degrees, and preferably 0 to -80 degrees, to provide adequate illumination when the lamp is worn around the neck without being overturned;
with the inclination 0 ° corresponding to the pivot of the lamp generating a horizontal light beam when the headlamp is positioned on the head of a user standing, eyes staring at the horizon.

Dans un mode de réalisation particulier, le bandeau comporte une partie avant plus ou moins rigide ou semi-rigide et une partie arrière réalisée avec un bandeau textile élastique, la liaison entre la partie avant et la partie arrière étant assurée par deux pièces de liaisons comportant des orifices pour le passage de conducteurs électriques. Les conducteurs électriques sont avantageusement intégrés, à l'avant, dans la partie rigide/semi-rigide avant du bandeau, en sorte que ceux-ci ne « sortent » qu'au niveau du bandeau textile élastique.In a particular embodiment, the strip comprises a front portion more or less rigid or semi-rigid and a rear portion made with an elastic textile strip, the connection between the front portion and the rear portion being provided by two pieces of links comprising orifices for the passage of electrical conductors. The electrical conductors are advantageously integrated, in the front, in the rigid / semi-rigid front part of the headband, so that they only "come out" at the level of the elastic textile headband.

De préférence, le bandeau comporte une alternance d'éléments rigides/semi-rigides conférant une rigidité suffisante à la lampe lorsqu'elle est portée en « tour de cou », l'amplitude du pivot de [- 45°, + 30°] et de préférence [- 80°, + 45 °] autorisant un réglage du faisceau lumineux dans diverses positions..Preferably, the strip comprises an alternation of rigid / semi-rigid elements conferring sufficient rigidity to the lamp when worn in "choker", the amplitude of the pivot of [- 45 °, + 30 °] and preferably [- 80 °, + 45 °] allowing adjustment of the light beam in various positions.

Dans un mode de réalisation particulier, la lampe peut être portée en tour de cou, en sorte que l'amplitude du pivot de [- 45°, + 30°] et de préférence [- 80°, + 45 °] permet d'ajuster le faisceau lumineux dans une large mesure, permettant un éclairage horizontal, mais également vers le bas.In a particular embodiment, the lamp can be worn around the neck, so that the amplitude of the pivot of [- 45 °, + 30 °] and preferably [- 80 °, + 45 °] allows adjust the light beam to a large extent, allowing horizontal illumination, but also downward.

Description d'un mode de réalisation préféréDescription of a preferred embodiment

L'on décrit à présent une lampe frontale améliorée en ce qu'elle permet de nouvelles utilisations particulièrement commode, notamment en tour du cou ou lorsqu'elle est accrochée à un support, comme une branche d'arbre.An improved headlamp is now described in that it allows new and particularly convenient uses, particularly around the neck or when it is hooked to a support, such as a tree branch.

La figure 2 illustre un premier mode de réalisation d'une lampe frontale conforme à la présente invention. La lampe frontale comporte une lampe 20 dotée d'une source lumineuse qui est fixée sur un bandeau permettant le maintien de la lampe frontale sur la tête d'un utilisateur. Le bandeau de la figure 2 est de nature mixte, comportant une partie avant rigide/semi-rigide 30 servant de support à la lampe 20 et une partie arrière qui pourra être, d'une manière conventionnelle, réalisée en un textile élastique 40. La partie avant rigide/semi-rigide présente une forme pré-cintrée suffisamment souple pour s'adapter à différentes formes de têtes, Deux pivots, respectivement 21 et 22, sont disposés sur la partie avant du bandeau pour permettre une liaison pivot d'un large pivotement inédit de la lampe 20 par rapport à la partie avant rigide/semi-rigide 30.The figure 2 illustrates a first embodiment of a headlamp according to the present invention. The headlamp has a lamp 20 having a light source which is fixed on a strip for holding the headlamp on the head of a user. The banner of the figure 2 is of mixed nature, having a rigid / semi-rigid front portion 30 serving as a support for the lamp 20 and a rear portion which may be, in a conventional manner, made of an elastic textile 40. The rigid / semi-rigid front part rigid has a pre-curved shape flexible enough to adapt to different shapes of heads, two pivots, respectively 21 and 22, are arranged on the front portion of the strip to allow a pivot connection of a large pivoting novelty of the lamp 20 with respect to the rigid / semi-rigid front part 30.

Plus spécifiquement, l'on considère le bandeau de la lampe 20 positionnée de manière conventionnelle sur la tête d'un utilisateur se tenant debout, les yeux fixés vers l'horizon et générant un faisceau horizontal servant de référence à une inclinaison de la lampe (inclinaison = 0°),More specifically, it is considered the headband of the lamp 20 positioned conventionally on the head of a user standing, the eyes fixed towards the horizon and generating a horizontal beam serving as a reference to an inclination of the lamp (inclination = 0 °),

Dans un mode de réalisation de l'invention, la lampe est configurée avec une liaison pivot égale à au moins [- 45°, + 30°] au moins et, de préférence, [- 80°, + 45 °] correspondant à une amplitude totale de 125 °.In one embodiment of the invention, the lamp is configured with a pivot connection of at least [- 45 °, + 30 °] at least and preferably [- 80 °, + 45 °] corresponding to a total amplitude of 125 °.

Grâce à cette disposition particulière inédite, lorsque la lampe frontale est positionnée sur la tête d'un utilisateur, un pivotement de [0, + 30°] permet un réglage approprié du faisceau lumineux. Il est à noter que dans cette position l'amplitude [-45°, 0°] ne serait pas utilisable dans cette circonstance car la lampe aurait tendance à venir « buter » contre le front de l'utilisateur.Thanks to this unique arrangement, when the headlamp is positioned on the head of a user, a rotation of [0, + 30 °] allows appropriate adjustment of the light beam. It should be noted that in this position the amplitude [-45 °, 0 °] would not be usable in this circumstance because the lamp would tend to "abut" against the front of the user.

En revanche, et c'est un avantage considérable de la présente invention, la lampe frontale peut à présent être directement positionnée, sans être « retournée à l'envers », en « tour de cou », tout en assurant un réglage convenable du faisceau lumineux grâce à l'amplitude [-45°,0°] au moins, comme cela est illustrée en figure 3.On the other hand, and this is a considerable advantage of the present invention, the headlamp can now be directly positioned, without being "turned upside down", in "choker", while ensuring a proper adjustment of the beam luminous thanks to the amplitude [-45 °, 0 °] at least, as illustrated in figure 3 .

Grâce à cette disposition particulièrement opportune, on obtient deux effets techniques particulièrement féconds :

  • En premier lieu, un pivot de [- 45°, + 30°] permet alors de venir régler le faisceau lumineux dans une large gamme d'utilisation, en lampe frontale ou en « tour de cou » . Dans l'une ou l'autre configuration, l'utilisateur pour ajuster le faisceau lumineux pour qu'il éclaire vers le bas ou, au contraire pour qu'il éclaire à l'horizontal. La lampe devient ainsi utilisable dans deux configurations alternatives, voire d'autres puisque la même facilité de réglage devient possible lorsque la lampe frontale est accrochée à un support ;
  • En second lieu, le pivot étant fixée sur une partie avant d'un bandeau qui est relativement rigide/semi-rigide, comme cela est représenté dans la figure 2, il en découle une grande stabilité de la lampe dans la configuration « tour de cou » qui peut alors être ajustée avec précision et facilité en fonction des besoins de l'utilisateur.
Thanks to this particularly timely arrangement, we obtain two particularly fruitful technical effects:
  • In the first place, a pivot of [- 45 °, + 30 °] makes it possible to adjust the light beam in a wide range of use, as a headlamp or as a "choker". In one or the other configuration, the user to adjust the light beam so that it lights down or, on the contrary so that it lights up horizontally. The lamp thus becomes usable in two alternative configurations, and even others since the same ease of adjustment becomes possible when the headlamp is hooked to a support;
  • Secondly, the pivot being fixed on a front portion of a strip which is relatively rigid / semi-rigid, as shown in FIG. figure 2 , it follows a great stability of the lamp in the configuration "choker" which can then be adjusted accurately and easily according to the needs of the user.

Comme on le voit, la combinaison des deux moyens de l'invention, un pivot d'une grande amplitude, d'au moins [- 45°, + 30°] sur un support rigide/semi-rigide , confère à la lampe frontale de nouvelles possibilités d'utilisation.As can be seen, the combination of the two means of the invention, a pivot of a large amplitude, of at least [- 45 °, + 30 °] on a rigid / semi-rigid support, gives the headlamp new possibilities of use.

Dans un mode de réalisation particulier, la lampe comporte une batterie fixée d'une manière conventionnelle à l'arrière du bandeau, au niveau du textile élastique. De préférence, la partie rigide/semi rigide du bandeau sera excavée de manière à permettre l'insertion de conducteurs électriques à l'intérieur de la partie avant rigide/semi-rigide 30 du bandeau. Deux éléments de liaison, respectivement 41 et 42 représentés sur la figure, permettent alors la liaison entre la partie avant 30 et le textile élastique 40. Ces deux éléments liaison permettent, de surcroît la sortie des conducteurs électriques hors de la partie rigide/semi-rigide, qui pourront alors prendre la forme du conducteur en spiral quelconque connecté, via un connecteur approprié, à la batterie situé à la l'arrière de la lampe (et non représentée).In a particular embodiment, the lamp comprises a battery fixed in a conventional manner at the rear of the strip, at the level of the elastic textile. Preferably, the rigid / semi-rigid portion of the strip will be excavated so as to allow insertion of electrical conductors within the rigid / semi-rigid front part 30 of the strip. Two connecting elements, respectively 41 and 42 shown in the figure, then allow the connection between the front portion 30 and the elastic textile 40. These two connecting elements allow, moreover the output of the electrical conductors out of the rigid / semi-rigid part. rigid, which can then take the form of any spiral conductor connected via a suitable connector to the battery located at the rear of the lamp (and not shown).

Dans d'autres modes de réalisation, comme ceux qui vont être décrits plus en détail à présent, et qui sont illustrées dans les figures suivantes, le bandeau de la lampe frontale pourra être avantageusement un bandeau complètement rigide/semi-rigide.In other embodiments, such as those which will be described in more detail now, and which are illustrated in the following figures, the headband of the headlamp may advantageously be a completely rigid / semi-rigid headband.

La figure 4 illustre une vue de droite d'un mannequin portant, autour de son cou, un second mode de réalisation d'une lampe frontale dotée d'un bandeau rigide/semi-rigide, conforme à la présente invention, dans lequel la lampe est montrée dans deux positions de pivot distinctes.The figure 4 illustrates a right view of a dummy wearing, around its neck, a second embodiment of a headlamp having a rigid / semi-rigid headband according to the present invention, wherein the lamp is shown in FIG. two distinct pivot positions.

La figure 5 illustre une vue de gauche d'un mannequin portant, autour de son cou, un mode de réalisation d'une lampe frontale conforme à la présente invention.The figure 5 illustrates a left view of a dummy wearing, around its neck, an embodiment of a headlamp according to the present invention.

La figure 6a illustre un second mode de réalisation d'un bandeau rigide/semi-rigide 50 d'une lampe frontale présentant un « arrière » qui descend avant de traverser le plan sagittal médian. Plus spécifiquement, le bandeau comporte une partie avant qui est rigide/semi-rigide, permettant la fixation d'une lampe via une liaison pivot, et qui est localisée approximativement dans un plan horizontal (x, y) correspondant à un plan transversal du porteur de la lampe. En première approximation, on a représenté le rayon de courbure R1 de la courbe 51 qui se situe dans le plan (x,y).The figure 6a illustrates a second embodiment of a rigid / semi-rigid headband 50 of a headlamp having a "back" which descends before crossing the median sagittal plane. More specifically, the strip comprises a front portion which is rigid / semi-rigid, allowing the attachment of a lamp via a pivot connection, and which is located approximately in a horizontal plane (x, y) corresponding to a transverse plane of the wearer. of the lamp. As a first approximation, the radius of curvature R1 of the curve 51, which lies in the plane (x, y), is represented.

En arrière de la partie avant - vers la droite dans la figure 5 - on voit que le bandeau 50 suit ensuite une courbe latérale qui s'inscrit approximativement dans un plan vertical (x, z) parallèle au plan sagittal de l'utilisateur et, à nouveau, on a représenté l'approximation du rayon de courbure R2.Behind the front - to the right in the figure 5 - It is seen that the strip 50 then follows a lateral curve which is approximately in a vertical plane (x, z) parallel to the sagittal plane of the user and, again, there is shown the approximation of the radius of curvature R2 .

En arrière du bandeau, le bandeau 50 suit une courbe arrière qui s'inscrit approximativement plutôt dans un plan (y, z) correspondant au plan frontal par rapport à l'utilisateur de la lampe et l'on voit l'approximation d'un rayon de « courbure » égal à R3...At the rear of the headband, the headband 50 follows a rear curve which is approximately in a plane (y, z) corresponding to the front plane with respect to the user of the lamp and the approximation of a radius of "curvature" equal to R3 ...

Par conséquent la plan sagittal médian sert de plan de symétrie et la partie en pointillé correspondant à la partie du bandeau située « derrière » le plan sagittal médian (x, z).Consequently, the median sagittal plane serves as a plane of symmetry and the dashed portion corresponds to the part of the strip located "behind" the median sagittal plane (x, z).

On voit que la partie arrière du bandeau 50 rigide/semi-rigide « descend » à présent avant de rencontrer le plan sagittal médian. Il ne s'agit là que d'un exemple de réalisation, nullement limitatif d'un bandeau complètement rigide/semi-rigide.It can be seen that the rear portion of the rigid / semi-rigid headband 50 "now" descends before meeting the median sagittal plane. This is only an example of embodiment, in no way limiting a completely rigid / semi-rigid headband.

Le bandeau 50 comporte donc :

  • une partie avant rigide/semi-rigide permettant la fixation d'une lampe 101 et offrant une certaine déformabilité suivant un premier plan (x, y) qui est approximativement un plan transversal ;
  • une partie latérale intermédiaire rigide/semi-rigide permettant une certaine déformabilité suivant approximativement un second plan (x, z) qui est un plan sagittal ;
  • une partie arrière rigide/semi-rigide assurant une certaine déformabilité suivant approximativement un troisième plan (y, z) qui est un plan frontal.
The strip 50 therefore comprises:
  • a rigid / semi-rigid front portion for fixing a lamp 101 and providing a certain deformability along a first plane (x, y) which is approximately a transverse plane;
  • a rigid / semi-rigid intermediate side portion allowing a certain deformability along approximately a second (x, z) plane which is a sagittal plane;
  • a rigid / semi-rigid rear portion providing a certain deformability along approximately a third plane (y, z) which is a frontal plane.

L'on obtient ainsi, grâce à cette disposition avantageuse, une forme tridimensionnelle qui est déformable, suivant l'un quelconque des plans ci-dessus, tout en préservant une longueur constante pour le bandeau 50.Thus, thanks to this advantageous arrangement, a three-dimensional shape which is deformable, according to any one of the above planes, is obtained while preserving a constant length for the strip 50.

Dans un mode de réalisation particulier, le bandeau 50 comporte une alternance d'élément rigides/semi-rigides (déformables). Les éléments rigides sont illustrés en clair sur la figure tandis que les éléments semi-rigides (déformables) sont représentés en foncé. Comme on le voit, le bandeau 50 de la figure 6a comporte une branche gauche dotée d'une partie avant 51 semi-rigide déformable (foncé) puis, de la gauche vers la droite:

  • une partie latérale 56 rigide (claire),
  • une partie latérale 54 semi-rigide (foncée),
  • une partie latérale 57 rigide (claire),
  • une partie latérale 52 semi-rigide (foncée),
  • une partie latérale 58 rigide (claire),
  • une partie arrière 53 semi-rigide (foncée).
In a particular embodiment, the strip 50 comprises an alternation of rigid / semi-rigid (deformable) elements. The rigid elements are illustrated in clear in the figure while the semi-rigid elements (deformable) are represented in dark. As we see, the band 50 of the figure 6a has a left branch with a front part 51 semi-rigid deformable (dark) then, from left to right:
  • a lateral part 56 rigid (clear),
  • a lateral portion 54 semi-rigid (dark),
  • a lateral part 57 rigid (clear),
  • a lateral part 52 semi-rigid (dark),
  • a rigid lateral portion 58 (clear),
  • a rear part 53 semi-rigid (dark).

Comme on le voit dans ce mode de réalisation spécifique, la partie avant 51, les parties latérales 54 et 52, et la partie arrière 53 qui sont toute semi-rigides, permettent la déformation du bandeau à longueur constante dans les trois plans (x, y), (x, z) et (y, z). Provoquant ainsi la variabilité des rayons de courbures R1, R2 et R3 permettant la fixation du bandeau 50 sur une tête de dimension quelconque, comme ce que l'on voit dans l'illustration de la figure 6b.As seen in this specific embodiment, the front portion 51, the lateral portions 54 and 52, and the rear portion 53 which are all semi-rigid, allow the deformation of the constant length band in the three planes (x, y), (x, z) and (y, z). Thus provoking the variability of the radii of curvature R1, R2 and R3 allowing the attachment of the strip 50 to a head of any size, as can be seen in the illustration of FIG. figure 6b .

On voit également dans la figure 6b que le bandeau 50 comporte des éléments rigides permettant la fixation et le passage d'un élastique, respectivement 150 et 151, pour assurer le serrage permettant de contraindre la déformation du bandeau rigide/semi-rigide suivant les trois plans, en réduisant les rayons de courbures R1-R3, comme cela est représenté dans le schéma de la figure 6a.We also see in the figure 6b that the strip 50 comprises rigid elements allowing the attachment and the passage of an elastic, respectively 150 and 151, to ensure the clamping to constrain the deformation of the rigid / semi-rigid strip along the three planes, reducing the radii of curvatures R1-R3, as shown in the diagram of the figure 6a .

Les figures 7 et 8 illustrent le détail d'une réalisation concrète d'un bandeau rigide/semi-rigide suivant le second mode de réalisation. Le bandeau comporte une alternance d'éléments rigides, représentés en clair sur les figures 7 et 8, et d'éléments plus souples qui sont représentés en foncé.The figures 7 and 8 illustrate the detail of a concrete embodiment of a rigid / semi-rigid strip according to the second embodiment. The headband has an alternation of rigid elements, represented in clear on the figures 7 and 8 , and more flexible elements that are represented in dark.

Dans un mode de réalisation particulier, les éléments pourront être réalisé en polyuréthane thermoplastique (TPU) ou en polyamide, polyester , PVC avec des grades choisis pour permettre la réalisation d'une structure rigide/semi-rigide offrant une structure stable (permettant même le positionnement du bandeau sur une table) tout en étant suffisamment déformable au moyen d'un élastique 150. En pratique, les éléments plus rigides présenteront un grade compris dans la gamme [_, 73SHD] tandis que les éléments plus souples (semi-rigides) présenteront un grade compris dans la plage de valeurs [_, 70SHA].In a particular embodiment, the elements may be made of thermoplastic polyurethane (TPU) or polyamide, polyester, PVC with grades chosen to allow the realization of a rigid / semi-rigid structure providing a stable structure (allowing even the positioning the band on a table) while being sufficiently deformable by means of an elastic 150. In practice, the more rigid elements will present a grade included in the range [_, 73SHD] while the more flexible elements (semi-rigid) will have a grade in the [_, 70SHA] range.

En référence à la figure 7 qui montre plus spécifiquement une vue de gauche du bandeau, celui-ci comporte une partie avant semi-rigide 100 sur laquelle sera fixée, via une liaison pivot, une lampe 101 comportant une ou plusieurs LED(s) associée(s) à son circuit électronique. La partie avant pourra être extrudée. De préférence, la lampe 101 comporte une pluralité de LEDs de puissance moyenne, et leur optique associées. De ce fait, la lampe prendra une forme relativement plate, avec une surface de dissipation de la chaleur importante, ce qui permettra de disposer directement les LEDs sur un circuit imprimé faisant office de radiateur. Il en résultera ainsi une lampe 101 particulièrement compacte.With reference to the figure 7 which more specifically shows a left view of the strip, it comprises a semi-rigid front portion 100 on which will be fixed, via a pivot connection, a lamp 101 having one or more LED (s) associated with its circuit electronic. The front part can be extruded. Preferably, the lamp 101 comprises a plurality of LEDs of average power, and their associated optics. As a result, the lamp will assume a relatively flat shape, with a large heat dissipation surface, which will allow the LEDs to be placed directly on a printed circuit serving as a radiator. This will result in a lamp 101 particularly compact.

Le bandeau comporte, en outre, une partie arrière 116 rigide (clair) formant une partie arrière du bandeau. Alternativement l'élément 116 pourra devenir semi-rigide (foncé) pour s'adapter sur le plan xy.The strip further comprises a rear portion 116 rigid (clear) forming a rear portion of the strip. Alternatively the element 116 may become semi-rigid (dark) to fit on the xy plane.

Le bandeau 20 comporte, sur sa branche de gauche, un premier élément rigide 111 (de rigidité supérieure à l'élément semi-rigide 100) ayant une première extrémité inférieure fixée à une première extrémité de la partie avant 100, ainsi qu'une seconde extrémité supérieure fixée à un second élément 112 semi-rigide (foncé, donc plus souple). L'élément rigide 111 comporte, respectivement à ses deux extrémités inférieure et supérieure, deux éléments de passage 111a et 111b pour un premier élastique de serrage 150.The strip 20 comprises, on its left-hand branch, a first rigid element 111 (of greater rigidity than the semi-rigid element 100) having a first lower end fixed to a first end of the front part 100, as well as a second upper end attached to a second element 112 semi-rigid (dark, so more flexible). The rigid element 111 comprises, respectively, its two lower and upper ends, two passage members 111a and 111b for a first clamping elastic 150.

Le second élément semi-rigide 112 comporte une première extrémité fixée à la seconde extrémité du premier élément 111 et une seconde extrémité fixée à une première extrémité d'un troisième élément rigide 113 servant de point de passage de l'élastique 150 provenant de l'élément 111b de la branche gauche.The second semi-rigid element 112 has a first end attached to the second end of the first element 111 and a second end attached to a first end of a third rigid element 113 serving as a point of passage of the elastic 150 coming from the element 111b of the left branch.

Le bandeau comporte ensuite un quatrième élément souple (semi-rigide) 114 disposant d'une première extrémité supérieure fixée à une seconde extrémité du troisième élément 113 et d'une seconde extrémité fixée à un cinquième élément rigide 115 permettant la fixation du premier élastique 150 provenant du point de passage 111a.The strip then comprises a fourth flexible element (semi-rigid) 114 having a first upper end attached to a second end of the third member 113 and a second end attached to a fifth rigid member 115 for fixing the first elastic member 150 from crossing point 111a.

On notera que suivant le mode de réalisation considéré, la partie arrière 116 pourra être rigide ou semi-rigide en sorte que les éléments 115 et 116 pourront être de fabrication ou non. Lorsque la partie arrière 116 sera semi-rigide (foncé), alors le cinquième élément rigide 115 sera distinct de cette dernière . Au contraire, si la partie arrière 116 est rigide, les éléments 115 et 116 pourront être identiques.Note that according to the embodiment considered, the rear portion 116 may be rigid or semi-rigid so that the elements 115 and 116 may be of manufacture or not. When the rear portion 116 is semi-rigid (dark), then the fifth rigid member 115 will be distinct from the latter. On the contrary, if the rear portion 116 is rigid, the elements 115 and 116 may be identical.

La branche gauche du bandeau est fixée enfin à une première extrémité de la partie arrière 116 via une seconde extrémité de l'élément rigide 115.The left branch of the strip is finally attached to a first end of the rear portion 116 via a second end of the rigid element 115.

La figure 8 illustre le détail de la branche de droite du bandeau qui est, comme on le voit , parfaitement symétrique par rapport à la branche droite. On y voit que la branche droite comporte un sixième élément rigide 121 ayant une première extrémité inférieure fixée à une seconde extrémité de la partie avant 100 ainsi qu'une seconde extrémité supérieure fixée à une première extrémité d'un septième élément souple (semi-rigide) 122. L'élément rigide 121 comporte, respectivement à ses deux extrémités inférieure et supérieure, deux éléments de passage 121a et 121b pour un second élastique de serrage 151.The figure 8 illustrates the detail of the right branch of the band which is, as we see, perfectly symmetrical with respect to the right branch. It can be seen that the straight branch comprises a sixth rigid element 121 having a first lower end attached to a second end of the front portion 100 and a second upper end attached to a first end of a seventh flexible element (semi-rigid 122. The rigid element 121 has, respectively at its two lower and upper ends, two passage elements 121a and 121b for a second clamping elastic 151.

L'élément souple 122 comporte une première extrémité fixée à l'élément 121 et une seconde extrémité fixée à un huitième élément rigide 123 servant de point de passage de l'élastique 151 provenant de l'éléments 121b de la branche gauche.The flexible element 122 has a first end attached to the element 121 and a second end attached to an eighth rigid element 123 serving as a point passage of the elastic 151 from the element 121b of the left branch.

Le bandeau comporte ensuite un neuvième élément souple (semi-rigide) 124 disposant d'une première extrémité supérieure fixée à une seconde extrémité de l'élément 123 et d'une seconde extrémité inférieure fixée à une première extrémité d'un dixième élément rigide 125 et permettant la fixation du second élastique 151 provenant du point de passage 121a.The strip then comprises a ninth flexible (semi-rigid) element 124 having a first upper end attached to a second end of the element 123 and a second lower end attached to a first end of a tenth rigid element 125 and allowing attachment of the second elastic 151 from the passage point 121a.

La branche droite du bandeau est enfin fixée à l'élément arrière (semi-rigide) 116 qui forme l'arrière du bandeau rigide/semi-rigide via une seconde extrémité de l'élément rigide 125.The right branch of the strip is finally attached to the rear (semi-rigid) element 116 which forms the rear of the rigid / semi-rigid strip via a second end of the rigid element 125.

La figure 9a illustre le détail de l'élément rigide 121 comportant, à ses deux extrémités 121a et 121b, les points de passage de l'élastique 151 permettant la contrainte sur le rayon de courbure R2 et , par conséquent, la déformation du bandeau dans le plan sagittal (x, z)
La figure 9b illustre un exemple d'une lampe 101 fixée sur la partie avant semi-rigide du bandeau, et ce au moyen d'un pivot présentant une large amplitude - égale au moins à [- 45°, + 30°] - sur un élément rigide à l'avant du bandeau. Cette fonction pivot de large amplitude permet, comme on le verra ci-après, une possibilité d'ajustement supplémentaire de la lampe frontale lorsque celle-ci est utilisée en « tour de cou ». Plus précisément, le pivot de la lampe frontale est avantageusement configurée pour permettre une rotation de 90° environ, ce qui permet une meilleure adaptabilité à la morphologie du porteur et donc améliore le confort. Cette rotation permet aussi d'augmenter considérablement l'équilibre de la lampe quand elle est posée sur une table par exemple.The figure 9a illustrates the detail of the rigid element 121 comprising, at its two ends 121a and 121b, the passage points of the elastic 151 allowing the stress on the radius of curvature R2 and, consequently, the deformation of the strip in the sagittal plane (x, z)
The figure 9b illustrates an example of a lamp 101 fixed on the semi-rigid front part of the strip, and this by means of a pivot having a large amplitude - equal to at least [- 45 °, + 30 °] - on a rigid element at the front of the headband. This pivot function of large amplitude allows, as discussed below, a possibility of additional adjustment of the headlamp when it is used in "neck". More specifically, the pivot of the headlamp is advantageously configured to allow a rotation of about 90 °, which allows a better adaptability to the morphology of the wearer and thus improves comfort. This rotation also makes it possible to considerably increase the balance of the lamp when it is placed on a table for example.

Dans un mode de réalisation particulier, le bandeau illustré dans les figures 7 et 8 comporte, à l'arrière une batterie d'alimentation 130 pour l'alimentation en courant de la lampe 101. De préférence, la batterie comporte, sur le dessus, un trou de passage pour les élastiques 150 et 151 avec un bouton de blocage 140. La figure 10 illustre une vue arrière du bandeau mettant clairement en évidence la batterie 130, le trou de passage des élastiques 150 et 151 et le bouton de blocage 140. Dans le schéma de la figure 10, on constate que la partie arrière 116 est réalisé en matériau rigide comme l'élément 116, en sorte que les deux éléments 115 et 116 sont réalisés à partir d'un même procédé de fabrication. Mais il ne s'agit que d'un mode de réalisation particulier car, une fois encore, l'élément 116 pourra être , optionnellement, en matériau semi-rigide.In a particular embodiment, the strip illustrated in the figures 7 and 8 comprises, at the rear, a battery 130 for supplying power to the lamp 101. Preferably, the battery comprises, on the top, a through hole for the elastics 150 and 151 with a locking button 140 . The figure 10 illustrates a rear view of the strip clearly showing the battery 130, the passage hole of the elastics 150 and 151 and the locking button 140. In the diagram of the figure 10 it is found that the rear portion 116 is made of rigid material such as the element 116, so that the two elements 115 and 116 are made from the same manufacturing process. But this is only a particular embodiment because, once again, the element 116 may be, optionally, semi-rigid material.

Comme on le voit, le bandeau forme une structure d'ensemble, constituée d'une alternance d'éléments rigides et semi-rigides, qui est relativement stable puisqu'elle peut être posée sur une table à la manière d'un objet quelconque. De cette manière, la lampe frontale pourra servir de lampe de table. Par ailleurs, la flexibilité des éléments souples permet une déformabilité du bandeau dans l'espace qui est réalisée par le serrage des élastiques 150 et 151 et leur blocage au niveau du bouton de blocage 140 situé sur le dessus de la batterie qui, elle également, pourra pivoter vers l'arrière en tant que de besoin.As can be seen, the band forms an overall structure, consisting of an alternation of rigid and semi-rigid elements, which is relatively stable since it can be placed on a table in the manner of any object. In this way, the headlamp can be used as a table lamp. Furthermore, the flexibility of the flexible elements allows a deformability of the strip in the space which is achieved by the tightening of the elastics 150 and 151 and their blocking at the blocking button 140 located on the top of the battery which, also, can rotate backwards as needed.

L'on réalise ainsi un bandeau présentant une nouvelle esthétique, une allure inédite et originale, qui est susceptible de rencontrer de nouvelles catégories de consommateurs, potentiellement rebutés par l'aspect « outil » des lampes frontales traditionnelles.Thus, a headband presenting a new aesthetic, a new and original look, which is likely to meet new categories of consumers, potentially put off by the "tool" aspect of traditional headlamps.

Par ailleurs, ce bandeau rigide/semi-rigide d'un nouveau type offre de multiples nouvelles fonctionnalités, comme on va le voir à présent.In addition, this rigid / semi-rigid band of a new type offers many new features, as we will see now.

Dans un mode de réalisation particulier, les branches gauche et/ou droite du bandeau sont creuses et leur longueur constante permet de venir y intégrer une pluralité de conducteurs électriques et/ou fibres optiques, On s'affranchit ainsi, d'une manière particulièrement élégante et fonctionnelle, des fils électriques que l'on connaît dans les lampes frontales conventionnelles dotées d'un bandeau élastique à longueur non constante. L'espace sera suffisant pour y intégrer, au sein des éléments rigides/souples, des conducteurs de puissance et des conducteurs de commande qui y seront ainsi particulièrement bien protégés.In a particular embodiment, the left and / or right branches of the strip are hollow and their constant length makes it possible to integrate a plurality of electrical conductors and / or optical fibers therein, thus eliminating, in a particularly elegant manner and functional, electrical son that is known in conventional headlamps with an elastic band non-constant length. The space will be sufficient to integrate, within the rigid / flexible elements, power conductors and control conductors which will be particularly well protected there.

Dans un mode de réalisation particulier, le bandeau comporte un feu arrière permettant la signalisation du porteur de la lampe. Ce feu arrière pourra être réalisé au moyen d'une lampe secondaire fixée sur la batterie 130 ou, alternativement, en venant déporter une fraction de la lumière créée par la lampe 101 grâce à une ou plusieurs fibres optiques. L'on peut ainsi avantageusement déporter de la lumière de l'avant vers l'arrière. Inversement, l'on peut également combiner une source lumineuse dans le boîtier arrière (rouge) avec un jeu de fibres optiques afin de venir déporter vers l'avant ou vers le côté une fraction de la lumière (rouge) générée par le boîtier arrière.In a particular embodiment, the strip comprises a rear light for signaling the lamp holder. This rear light can be achieved by means of a secondary lamp attached to the battery 130 or, alternatively, by deporting a fraction of the light created by the lamp 101 through one or more optical fibers. It can thus advantageously deport light from the front to the back. Conversely, it is also possible to combine a light source in the rear housing (red) with a set of optical fibers to move forward or to the side a fraction of the light (red) generated by the rear housing.

Dans un mode de réalisation particulier, la partie avant 100, voire les branches rigides 111 et 121 sont équipés de commutateurs permettant la commande des fonctionnalités de la lampe, ce que n'offrait assurément pas les bandeaux conventionnels. Alternativement et/ou cumulativement on peut prévoir un ou plusieurs afficheurs permettant de réaliser une ergonomie homme-machine ( IHM) avantageuse.In a particular embodiment, the front portion 100 or rigid branches 111 and 121 are equipped with switches for controlling the functionality of the lamp, which certainly did not offer the conventional strips. Alternatively and / or cumulatively one or more displays can be provided to achieve a man-machine ergonomics (HMI) advantageous.

Dans un autre mode de réalisation particulier, les branches gauche et droite du bandeau sont conçues pour être lumineuse de manière à permettre un signalement latéral efficace du porteur de la lampe.In another particular embodiment, the left and right branches of the strip are designed to be illuminated so as to allow effective lateral signaling of the lamp holder.

Claims (9)

  1. A headlamp comprising:
    - a lamp (20);
    - a band (30, 40) for holding said lamp (20) on the head of a user, said band (30, 40) having a front portion (30) rigid/semi-rigid flexible enough to adapt to different head shapes for supporting said lamp (20); wherein said lamp (20) is attached to said front portion (30) via a pivot connection (21, 22) allowing rotation with a first amplitude and a second amplitude;
    characterized in that said connexion (21, 22) is configured to allow a rotation having:
    - a first amplitude of at least 0 to + 30 degrees, and preferably 0 to 45 degrees, to provide adequate illumination when the lamp is conventionally carried around the head ;
    - a second amplitude ranging from at least 0 to -45 degrees, and preferably 0 to -80 degrees, to provide adequate illumination when the lamp is carried around the neck without being reversed,
    wherein the "0 degree" inclination corresponding to the pivot of the lamp when the latter generates a horizontal light beam when the headlamp is positioned on the head of a standing user, the eyes fixing the horizon
    wherein said second amplitude of at least 0 to - 45 degrees is unusable when the headlamp is positioned on the head because it tends to abut the lamp against the front of the user but allows the adjustment of the light beam when the lamp is positioned around the neck.
  2. The headlamp according to claim 1 characterized in that the headband (30, 40) comprises a rigid/semi-rigid front portion (30) which has a flexible pre-bent shape adaptable to different head shapes, and a rear portion (40) made with an elastic textile headband, the connection between the front portion and the rear portion being provided by two connecting pieces having orifices for the passage of electrical conductors, said electrical conductors being integrated, in the front, in the rigid/semi-rigid front part of the band, in which the flexible pre-bent portion provides stability to the lamp when worn around the neck.
  3. The headlamp according to claim 1 characterized in that the headband (30, 40) comprises an alternation of rigid/semi-rigid elements conferring sufficient rigidity to the lamp when it is worn in "round neck", said pivot connection being configured to allow a adjustment of the light beam in various positions ..
