Definitions
- the present invention relates to headlamps and in particular a device for holding a headlamp strip.
- Headlamps originally used in coal mines, have been very successful in the leisure sector, particularly speleology and hiking. They also figure prominently in the range of professional tools.
- the most recent headlamps have a high-power light source, located at the front, and a heavy-duty battery pack which is located at the rear.
- the figure 1 illustrates a first type of known headband, marketed by the applicant company, making it possible to ensure the attachment to the head of a user of a headlamp provided with a fairly large battery, fixed to the belt.
- the figure 2 illustrates a second example of a fairly bulky fastening device comprising several fixing bands, as described in the patent application EP2462825 , allowing the attachment of a protective helmet or welding mask on the head of a user.
- the figure 3 illustrates another example of a fastening system, as described in the patent FR3047570 allowing the fixing of glasses
- the present invention aims to provide a headlamp with a new type of rigid / semi-rigid headband allowing wide possibilities of adjustment on various heads of users.
- Another object of the present invention to provide a headlamp with a light support band and with a load balancing system between the weight of the lamp and that - more importantly - of the battery pack .
- the fastening elements are removable, for example by clipping.
- the first ends (A, A ') of the first and second strands are fixed via a sliding element making it possible to vary the position of the points A and A' on the strip.
- the second ends (B, B ') of the first and second strands are merged at the same point located close to the battery at the rear of the strip.
- the strip is of constant length, symmetrical with respect to a median sagittal plane, and comprises an alternation of rigid / semi-rigid elements to allow deformation in space and adjustment to the head of a user. .
- the invention is particularly suitable for producing a compact lamp comprising the light module and a relatively heavy power source.
- the load balancing device which will be described below is perfectly suited to the production of a headlamp comprising a rigid / semi-rigid retaining strip offering a structure that is particularly easy to adjust, allowing perfect retention of the lamp even when it has, in particular, a particularly heavy battery at the rear. It should be noted that the device could also be advantageous in the case of a remote battery to allow load balancing when the strip supports a particularly heavy headlamp which would tend to destabilize the headlamp forwards. Consequently, the embodiments which will be described below provide a significant solution for rebalancing the loads which would appear either at the front or at the rear of the retaining strip.
- the balancing device described below proves to be usable for any type of headlamp, and any type of headband, elastic or not, the device will be more specifically described in relation to a specific headlamp, such as described in the European patent application EP3290785 , entitled “ Headlamp with a rigid or semi / rigid headband ", filed on August 28, 2017 by the applicant of this patent application, which allows the realization of a light headlamp, well balanced and perfectly aesthetic.
- This new type of headlamp has a rigid / semi-rigid headband that makes a “break” with conventional headbands, bringing a new aesthetic but also new functionalities for almost immediate adjustment of the headband on the head of a user.
- This headlamp uses for this purpose a specific headband presenting a combination of rigid / semi-rigid structures of constant length and belonging to a family of shapes three-dimensional likely to deform in space, in several planes.
- This strip allows it to maintain a constant length, while allowing deformations along the three planes, which allows the strip to match the shape of the head of a user.
- the front part 21, the side parts 24 and 22, and the rear part 23 which are all semi-rigid, allow the deformation of the strip at constant length in the three planes (x, y), (x, z) and (y , z), thus causing the variability of the rays of curves R1, R2 and R3 allowing the fixing of the strip 10 on a head of any dimension.
- the figure 4b illustrates the positioning of the headband on the head of a user, without the lamp supply battery, while the figure 4c shows the strip with a supply battery 38 at the rear, as well as a device 39 for fixing the tightening elastic.
- the figure 4d illustrates a front perspective of the same banner illustrated in the figures 4a-4c , where we can clearly see the lamp 40 located at the front and the battery 38 in the rear position.
- FIGS. 5a and 5b show more specifically the detail of a first simplified embodiment of a strip 50 comprising an alternation of deformable semi-rigid elements (in dark) and rigid elements (in light), allowing the deformation of the strip at constant length in the three planes (x, y), (x, z) and (y, z) and the variability of the angles of curvature R1, R2 and R3, respectively.
- the figure 5a more specifically shows the left arm of the first embodiment which comprises a semi-rigid front part 100, on which is fixed a rigid part called “plate” serving as support, via a pivot connection, to a lamp 101 comprising one or more LEDs (s) associated with an optical system and a corresponding electronic circuit.
- the front part can be extruded.
- the strip also comprises a rigid rear part 116 (clear) forming a rear part of the strip.
- the element 116 may become semi-rigid to adapt to the xy plane.
- the strip comprises, on its left branch, a first rigid element 111 (of rigidity greater 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 end upper fixed to a second semi-rigid element 112 (dark, therefore more flexible).
- the rigid element 111 comprises, respectively at its two lower and upper ends, two passage elements 111a and 111b for a first tightening elastic 150.
- the second semi-rigid element 112 has a first end fixed to the second end of the first element 111 and a second end fixed to a first end of a third rigid element 113 serving as a point of passage for the elastic 150 coming from the elements 111b of the left branch.
- the strip then comprises a fourth flexible (semi-rigid) element 114 having a first upper end fixed to a second end of the third element 113 and a second end fixed to a fifth rigid element 115 allowing the fixing of the first elastic 150 from crossing point 111a.
- a fourth flexible (semi-rigid) element 114 having a first upper end fixed to a second end of the third element 113 and a second end fixed to a fifth rigid element 115 allowing the fixing of the first elastic 150 from crossing point 111a.
- the left branch of the strip is finally fixed to a first end of the rigid or semi-rigid strip 116 forming the rear part of the rigid / semi-rigid strip, via a second end of the rigid strip 115.
- the rear part 116 can be rigid or semi-rigid so that the elements 115 and 116 can be manufactured or not.
- the fifth rigid element 115 will be distinct from the latter.
- the elements 115 and 116 may be identical.
- the figure 5b illustrates the detail of the right branch of the strip which is, as we can see, perfectly symmetrical with respect to the left branch.
- the straight branch comprises a sixth rigid element 121 having a first lower end fixed to a second end of the front part 100 as well as a second upper end fixed to a first end of a seventh flexible element ( semi-rigid) 122.
- the rigid element 121 comprises, respectively at its two lower and upper ends, two passage elements 121a and 121b for a second tightening elastic 151.
- the flexible element 122 has a first end fixed to the element 121 and a second end fixed to an eighth rigid element 123 serving as a point of passage for the elastic 151 coming from the elements 121b of the left branch.
- the strip then comprises a ninth flexible (semi-rigid) element 124 having a first upper end fixed to a second end of the element 123 and a second lower end located at a first end of a tenth rigid element 125 and allowing the fixing of the second elastic 151 coming from the crossing point 121a.
- a ninth flexible (semi-rigid) element 124 having a first upper end fixed to a second end of the element 123 and a second lower end located at a first end of a tenth rigid element 125 and allowing the fixing of the second elastic 151 coming from the crossing point 121a.
- the straight branch of the strip is finally fixed 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.
- the rigid element 121 has, at its two ends 121a and 121b, the points of passage 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 5c shows the positioning of the rigid / semi-rigid strip on the head of a user with, highlighted, the role of the elastic bands 150 and 151, making it possible to constrain the deformation of the rigid / semi-rigid strip according to the three planes , reducing the radii of curvature R1-R3 and finally adjusting the tightness of the headband on the head of a user.
- This first embodiment of a rigid / semi-rigid strip illustrated in detail in the figures 5a and 5b proves to be perfectly suited for the production of a light headlamp capable of holding in place a headlamp 101 situated at the front and, at the rear, a battery pack 130, even a large one.
- headlamps are today such that there is a tendency to associate light sources of relatively light LED type - but nevertheless of high brightness - with a relatively heavy supply battery. This is how we notice a difference significant weight between the weight of the lamp 101 present at the front of the strip and that of the battery 130 disposed at the rear.
- the rigid / semi-rigid headband is equipped, as we will now see with the figures 6 and following, of a perfectly specific balancing device which, if it proves to be perfectly suited to the type of rigid / semi-rigid strip may nevertheless be installed on any type of more conventional strip.
- the figure 6 illustrates a top view of a first preferred embodiment of a rigid / semi-rigid strip provided with a load balancing device.
- the device comprises two strands 200 and 300, not extensible, each provided with a first end (resp. 210, 310) and a second end (resp. 220, 320).
- the first end 210 (point A) of the strand 200 is fixed on a front part of the left branch of the strip while the second end 220 (point B) of the strand 200 is fixed to a rear element of the strip.
- the first end 310 (point A ') of the strand 300 is fixed to a front part of the straight branch of the strip while the second end 320 (point B') of the strand 300 is fixed to a rear element of the banner.
- the fixing points A, B, A 'and B' may be permanent or removable, for example by clipping, knot etc ...
- the strip may include a plurality of clip positions enabling the fastening elements to be fixed at several possible locations.
- the two strands are threaded inside an element 400, preferably sliding, making it possible to make a junction C between the two strands 200 and 300.
- the sliding element 400 can be made of any material (plastic , metal, textile) of various shapes (ring, textile).
- the sliding element may consist of two pulleys whose axes are parallel and substantially vertical.
- the figure 7 illustrates the operating principle of the balancing device based on the sliding element 400 which makes it possible to bring the two strands 200 and 300 together at a point C. It will also be observed that the ends B and B 'are close, while the ends A and A 'are relatively distant.
- slightly elastic strands 200 and 300 will be chosen, wide enough to provide comfort for the user, and thin enough not to excessively increase the weight of the strip.
- the sliding element 400 may be made of injected plastic with a shape studied for the comfort of the user, in particular exposing large refined and curved surfaces for optimal contact with the head of the user.
- the sliding element 400 is endowed with a mechanism for tightening the strands 200 and 300, which further accentuates the possibilities of adjusting the strip.
- the ends A, B, A 'and B' are fitted with fixing elements on the rigid / semi-rigid strip respectively 210, 220, 310 and 320 which can be fixed or removable by clipping for example, so that the device balancing based on the sliding element 400 may itself be a removable accessory, useful for certain activities.
- the headlamp can be used in its “refined” form, as shown in the figures 5a and 5b .
- the user wishes to engage in a more “dynamic” activity, such as running, for example, he will find an appreciable advantage in the installation of the balancing device based on the two strands 200 and 300 and the sliding element 400.
- the attachment points will be positioned on rigid elements making up the rigid / semi-rigid strip. Alternatively, they can be positioned on more flexible elements.
- FIGS. 8a, 8b , 8c, 8d and 8th illustrate several perspective views of a second embodiment of a more sophisticated rigid / semi-rigid strip, comprising fixing points A and A ′ fixed respectively to the front part, while the two rear fixing points B and B 'are arranged on the elements 113 and 123 of the left and right branches of the strip.
- the fixing points are produced by means of clips which are configured to be able to be placed in one or more notches arranged on the sides of the strip so as to allow adjustable fixing.
- the attachment points can also be produced by means of slides allowing lateral movement of the attachment points on each side of the headlamp retaining strip.
- the figure 9 illustrates how to obtain, as the sliding element 400 slides (point C), various possibilities for adjusting the strip on the user's head.
- the strands 200 and 300 gradually come to conform to the shape of the head. The efforts are thus distributed in good part on the top of the head, increasing the comfort and the stability of the headlamp.
- the figures 10, 11 and 12 illustrate the way in which a user can, thanks to the advantageous arrangement of the invention, position the headlamp on his head and cause the adjustment of the strip by manipulating the sliding element 400 with one hand.
- the figure 13 illustrates a third embodiment in which the attachment points B and B ′ are made to coincide on the battery 130, when the latter is arranged at the rear of the headlamp.
- this arrangement can be provided even in the absence of a battery at the rear, when the headlamp comprises, for example, a remote battery.
- the attachment points may advantageously be fixed to rear attachment points of the strip.
- the load balancing device has an attachment point at the rear which is based on the "tanka" usually used for adjusting the strip.
- the sliding element 400 can be replaced by a seam, as in the example of Figures 16a and 16b , and it is the same "tanka" which is used for the adjustment of the strip which also allows the adjustment of the load balancing device.
- the figure 15a to 15c illustrate three different variants of the sliding element 400.
- the figure 15a recalls the preferred form of the sliding element 400 which is the form used in the embodiments which have been described in relation to the preceding figures.
- the figure 15b illustrates a second variant in which the sliding element 500 comprises two independent slides, respectively based on two parts 510 and 520, respectively left and right, into which each of the two strands 200 and 300 would be threaded.
- Each of the parts 510 and 520 could thus slide along the two strands, in order to reveal two junction points C and C '.
- Such an arrangement proves to be particularly advantageous when the rear attachment points are particularly distant, as illustrated in the second embodiment of the figures 8a-8e , since it becomes possible to adjust the device by independently sliding each of the parts 510 and 520. With thus a double possibility of adjustment, at the front and at the rear, with a "triangle opening" both at front and back.
- the double slide formed by the parts 510 and 520 is made of deformable plastic material, which makes it possible to obtain two slides deformable under the tension of the strands 200 and 300, which could thus facilitate the tightening of the device. load distribution by simple friction or friction on the deformable parts 510 and 520.
- the slide element comprises three distinct non-deformable parts, namely a left element 610, a central element 620 and a right element 630, making it possible to cause significant changes in direction of each of the two strands 800 and 900 used to connect the points of 'fasteners A, A', B and B 'on the retaining strip. So we get thanks in this configuration a crossing of the links and a fairly significant friction allowing the tightening of the device on the skull of the user.
- FIGS 16a and 16b illustrate a fifth embodiment of a load balancing device, in which there is, instead of the slide 400 present on the two strands 200 and 300 - only the strand 200 being shown in the figure 16b - a seam 1010 to connect the two strands 200 and 300 at a fixed point C.
- the attachment point A is embodied, in this embodiment, by a textile placed on the retaining strip comprising a loop 1020 in which comes s 'thread the strand 200 and then go to join a fixation on a sliding element 1030 positioned on the strip. Thanks to this configuration, a simple and nevertheless effective adjustment possibility is thus obtained.

Le dispositif d'équilibrage de charges que l'on va décrire ci-après est parfaitement adapté à la réalisation d'une lampe frontale comportant un bandeau de maintien rigide/semi-rigide offrant une structure particulièrement aisée à régler, permettant un parfait maintien de la lampe même lorsque celle-ci comporte, notamment, une batterie particulièrement lourde à l'arrière. Il convient de noter que le dispositif pourra également être avantageux dans le cas d'une batterie déportée pour permettre l'équilibrage des charges lorsque le bandeau soutient une lampe frontale particulièrement lourde et qui tendrait à déstabiliser la lampe frontale vers l'avant. Par conséquent, les modes de réalisation qui vont être décrits plus loin apportent une solution significative pour ré-équilibrer des charges qui se présenteraient soit à l'avant, soit à l'arrière du bandeau de maintien.The load balancing device which will be described below is perfectly suited to the production of a headlamp comprising a rigid / semi-rigid retaining strip offering a structure that is particularly easy to adjust, allowing perfect retention of the lamp even when it has, in particular, a particularly heavy battery at the rear. It should be noted that the device could also be advantageous in the case of a remote battery to allow load balancing when the strip supports a particularly heavy headlamp which would tend to destabilize the headlamp forwards. Consequently, the embodiments which will be described below provide a significant solution for rebalancing the loads which would appear either at the front or at the rear of the retaining strip.
Bien que le dispositif d'équilibrage décrit ci-après s'avère utilisable pour tout type de lampe frontale, et tout type de bandeau, élastique ou non, l'on décrira plus spécifiquement le dispositif en relation avec une lampe frontale spécifique, telle que décrite dans la demande de brevet européen
L'on rappelle la structure générale d'un bandeau rigide/semi-rigide en relation avec les
Ce nouveau type de lampe frontale comporte un bandeau rigide/semi-rigide venant réaliser une « rupture » avec les bandeaux conventionnels, apportant une nouvelle esthétique mais également de nouvelles fonctionnalités d'ajustement quasi-immédiat du bandeau sur la tête d'un utilisateur. Cette lampe frontale utilise à cet effet un bandeau spécifique présentant une combinaison de structures rigides/semi-rigides de longueur constante et appartenant à une famille de formes tridimensionnelles susceptibles de se déformer dans l'espace, suivant plusieurs plans.This new type of headlamp has a rigid / semi-rigid headband that makes a “break” with conventional headbands, bringing a new aesthetic but also new functionalities for almost immediate adjustment of the headband on the head of a user. This headlamp uses for this purpose a specific headband presenting a combination of rigid / semi-rigid structures of constant length and belonging to a family of shapes three-dimensional likely to deform in space, in several planes.
Plus spécifiquement, le bandeau comporte:
- une partie avant rigide/semi-rigide permettant une certaine déformabilité suivant un premier plan (x, y) qui est un plan transversal ;
- une partie intermédiaire rigide/semi-rigide permettant une certaine déformabilité suivant un second plan (x, z) qui est un plan sagittal ;
- une partie arrière rigide/semi-rigide permettant une certaine déformabilité suivant un troisième plan (y, z) qui est un plan frontal.
- a rigid / semi-rigid front part allowing a certain deformability along a first plane (x, y) which is a transverse plane;
- a rigid / semi-rigid intermediate part allowing a certain deformability along a second plane (x, z) which is a sagittal plane;
- a rigid / semi-rigid rear part allowing a certain deformability in a third plane (y, z) which is a frontal plane.
La forme tridimensionnelle de ce bandeau lui permet de conserver une longueur constante, tout en autorisant des déformations suivant les trois plans, ce qui permet au bandeau d'épouser la forme de la tête d'un utilisateur.The three-dimensional shape of this strip allows it to maintain a constant length, while allowing deformations along the three planes, which allows the strip to match the shape of the head of a user.
En se référant plus spécifiquement au schéma de la

- une partie latérale 24 semi-rigide (foncée),
- une partie latérale 27 rigide (claire),
- une partie latérale 22 semi-rigide (foncée),
- une partie latérale 28 rigide (claire),

La partie avant 21, les parties latérales 24 et 22, et la partie arrière 23 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 10 sur une tête de dimension quelconque.The

Le bandeau comporte, en outre, une partie arrière 116 rigide (claire) formant une partie arrière du bandeau. Alternativement, l'élément 116 pourra devenir semi-rigide pour s'adapter sur le plan xy.The strip also comprises a rigid rear part 116 (clear) forming a rear part of the strip. Alternatively, the
Le bandeau 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 comprises, on its left branch, a first rigid element 111 (of rigidity greater than the semi-rigid element 100) having a first lower end fixed to a first end of the
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'éléments 111b de la branche gauche.The second
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 (semi-rigid)
La branche gauche du bandeau est fixée enfin à une première extrémité de l'élément rigide ou semi-rigide 116 formant la partie arrière du bandeau rigide/semi-rigide, via une seconde extrémité de l'élément rigide 115. 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.The left branch of the strip is finally fixed to a first end of the rigid or

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
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 située 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)
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 straight branch of the strip is finally fixed to the rear (semi-rigid)
Comme on le voit dans la figure, l'élément rigide 121 comporte, 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).As seen in the figure, the

Les caractéristiques technologiques des lampes frontales sont aujourd'hui telles que l'on a tendance à associer des sources lumineuses de type LED relativement légère - mais néanmoins de forte luminosité - avec une batterie d'alimentation relativement lourde. C'est ainsi que l'on note une différence significative de poids entre le poids de la lampe 101 présente à l'avant du bandeau et celui de la batterie 130 disposée à l'arrière.The technological characteristics of headlamps are today such that there is a tendency to associate light sources of relatively light LED type - but nevertheless of high brightness - with a relatively heavy supply battery. This is how we notice a difference significant weight between the weight of the
Il en résulte un déséquilibre assez important qui peut être source d'inconfort et de gêne pour l'utilisateur, surtout dans certaines situations de mouvements intenses, comme par exemple lors d'une course à pied.This results in a fairly large imbalance which can be a source of discomfort and discomfort for the user, especially in certain situations of intense movement, such as during a running race.
Pour augmenter significativement la sensation de confort, mais également l'équilibrage de la lampe frontale, le bandeau rigide/semi-rigide est équipé, comme on va le voir à présent avec les
La
Le dispositif comporte deux brins 200 et 300, non extensibles, dotés chacun d'une première extrémité (resp. 210, 310) et d'une seconde extrémité (resp. 220, 320).The device comprises two
La première extrémité 210 (point A) du brin 200 est fixée sur une partie avant de la branche gauche du bandeau tandis que la seconde extrémité 220 (point B) du brin 200 est fixée à un élément arrière du bandeau. D'une manière similaire, la première extrémité 310 (point A') du brin 300 est fixée sur une partie avant de la branche droite du bandeau tandis que la seconde extrémité 320 (point B') du brin 300 est fixée à un élément arrière du bandeau.The first end 210 (point A) of the
Dans un mode de réalisation particulier, les points de fixation A, B, A' et B' pourront être permanent ou amovible, par exemple par clipsage, nœud etc...In a particular embodiment, the fixing points A, B, A 'and B' may be permanent or removable, for example by clipping, knot etc ...
Alternativement, le bandeau peut comporter une pluralité de position de clipsage permettant de fixer les éléments d'attache à plusieurs endroits possibles.Alternatively, the strip may include a plurality of clip positions enabling the fastening elements to be fixed at several possible locations.
Par ailleurs, les deux brins sont enfilés à l'intérieur d'un élément 400, de préférence coulissant, permettant de réaliser une jonction C entre les deux brins 200 et 300. L'élément coulissant 400 pourra être réalisé en un matériau quelconque (plastique, métal, textile) de forme diverses (anneau, textile). Dans un mode de réalisation particulier, l'élément coulissant pourra être constitué de deux poulies dont les axes sont parallèles et sensiblement verticaux.Furthermore, the two strands are threaded inside an

Il en résulte un double effet technique, à savoir un ajustement complémentaire du bandeau sur la tête de l'utilisateur et également la mise en place d'un élément de maintien supplémentaire réalisé par l'élément 400 et les deux brins prenant appui sur la tête de l'utilisateur.This results in a double technical effect, namely an additional adjustment of the strip on the head of the user and also the installation of an additional holding element produced by the
Ce qui assure une meilleure disposition des charges même lorsque les poids respectifs de la source lumineuse 101 et de la batterie 130 s'avèrent être très distincts.This ensures a better arrangement of the charges even when the respective weights of the
Dans des modes de réalisation particuliers, on choisira des brins 200 et 300 légèrement élastiques, assez larges pour assurer un confort pour l'utilisateur, et suffisamment fins pour ne pas alourdir de manière excessive le poids du bandeau. L'élément coulissant 400 pourra être réalisé en plastique injecté avec une forme étudiée pour le confort de l'utilisateur, en particulier exposant des larges surfaces affinées et galbées pour un contact optimal avec la tête de l'utilisateur.In particular embodiments, slightly
Dans un mode de réalisation particulier, on dote l'élément coulissant 400 d'un mécanisme de serrage des brins 200 et 300, ce qui permet d'accentuer encore les possibilités d'ajustage du bandeau. Les extrémités A, B, A' et B' sont équipées d'éléments de fixation sur le bandeau rigide/semi-rigide respectivement 210, 220, 310 et 320 qui pourront être fixes ou amovibles par clipsage par exemple, en sorte que le dispositif d'équilibrage basé sur l'élément coulissant 400 pourra être lui-même un accessoire amovible, utile pour certaines activités. Ainsi, pour des activités plutôt « statiques », l'on pourra utiliser la lampe frontale sous sa forme « épurée », telle que représentée dans les
Plusieurs variantes sont possibles pour la disposition précise des points de fixation A, B, A' et B'.Several variants are possible for the precise arrangement of the fixing points A, B, A 'and B'.
Dans un mode de réalisation particulier, on viendra positionner les points de fixation sur des éléments rigides composants le bandeau rigide/semi-rigide. Alternativement, ils pourront être positionnés sur des éléments plus souples.In a particular embodiment, the attachment points will be positioned on rigid elements making up the rigid / semi-rigid strip. Alternatively, they can be positioned on more flexible elements.
Les
De préférence, les points de fixation sont réalisés au moyen de clips qui sont configurés pour pouvoir être placés dans une ou plusieurs encoches disposées sur les côtés du bandeau de manière à permettre une fixation réglable. Alternativement, les points de fixation pourront être également réalisés au moyens de coulisseaux permettant un déplacement latéral des points de fixation sur chaque côté du bandeau de maintien de la lampe frontale.Preferably, the fixing points are produced by means of clips which are configured to be able to be placed in one or more notches arranged on the sides of the strip so as to allow adjustable fixing. Alternatively, the attachment points can also be produced by means of slides allowing lateral movement of the attachment points on each side of the headlamp retaining strip.
