The present invention relates to a protective eyewear comprising: a frame resting on the face by a flexible back, the frame receiving a screen, and provided on each side with a hoop for fixing the ends of the headband , the frame comprising a middle arch in the upper part, a nasal arch in the lower part, two lateral loops each formed of a top segment of an intermediate segment mon tant (32, 232) and of a low segment, the high segment and the low segment being connected respectively to one side of the arch and to one side of the nasal arch.
ETAT DE LA TECHNIQUE STATE OF THE ART
De telles lunettes de protection existent sous de multiples variantes. Such protective glasses exist in many variations.
Un problème récurrent des lunettes de protection de moto est la ventila tion du volume compris entre la lunette et le visage, volume dans lequel la transpiration crée une atmosphère humide qui, au contact de l’air froid venant sur l’écran de la lunette risque de générer de la buée. A recurring problem with motorcycle protective eyewear is the ventilation of the volume between the glasses and the face, a volume in which perspiration creates a humid atmosphere which, in contact with the cold air coming on the screen of the glasses, risks generate steam.
Il existe certes, des ouvertures dans le dos de la lunette, c’est-à-dire la bande souple qui permet d’appliquer le cadre de la lunette contre vi sage. Toutefois, cette ventilation n’est pas suffisante d’autant plus que les ouvertures de cette bande périphérique sont orientées transversale ment à la direction de circulation de l’air passant sur les côtés de la tête. There are certainly openings in the back of the bezel, that is to say the flexible band which allows the frame of the bezel to be applied against the face. However, this ventilation is not sufficient especially since the openings of this peripheral band are oriented transversely to the direction of air circulation passing over the sides of the head.
BUT DE L’INVENTION PURPOSE OF THE INVENTION
L’invention a pour but de développer une lunette de protection compor tant un moyen efficace de régler la ventilation du volume d’air entre la lunette et le visage de l’utilisateur. The aim of the invention is to develop a protective eyewear comprising an efficient means of controlling the ventilation of the air volume between the eyewear and the face of the user.
EXPOSE ET AVANTAGES DE L’INVENTION DISCLOSURE AND ADVANTAGES OF THE INVENTION
A cet effet, l’invention a pour objet une lunette de protection compre nant : un cadre s’appuyant sur le visage par un dos souple, le cadre re cevant un écran, et muni sur chaque côté, d’un arceau pour la fixation des extrémités du bandeau, le cadre comprenant une arche médiane en partie haute, une voûte nasale en partie basse, deux boucles latérales formées chacune d’un segment haut d’un segment intermédiaire mon tant et d’un segment bas, le segment haut et le segment bas étant reliés respectivement à un côté de l’arche et à un côté de la voûte nasale, l’arche médiane forme un évent transversal muni d’un volet coulissant, réglable entre une position de fermeture et jusqu’à une position d’ouver ture complète de l’évent. To this end, the invention relates to a protective eyewear comprising: a frame resting on the face by a flexible back, the frame receiving a screen, and provided on each side with a hoop for fixing of the ends of the band, the frame comprising a median arch in the upper part, a nasal arch in the lower part, two lateral loops each formed of a top segment of an intermediate segment mon tant and a low segment, the upper segment and the lower segment being connected respectively to one side of the arch and to one side of the nasal arch, the arch median forms a transverse vent provided with a sliding shutter, adjustable between a closed position and up to a fully open position of the vent.
Cette lunette de protection a l’avantage de pouvoir régler efficacement la ventilation du volume situé derrière la lunette et en particulier au ni veau du front, surface qui, en générale est source de fortes transpira tions, notamment pendant un effort physique intense, tout en tenant compte pour le réglage de l’évent, de paramètres tels que la température de l’air ou la vitesse de circulation pour garantir une ventilation opti male et confortable du volume d’air entre la lunette et le visage du con ducteur. This protective goggles has the advantage of being able to effectively adjust the ventilation of the volume located behind the goggles and in particular at the level of the forehead, a surface which, in general, is a source of heavy perspiration, in particular during intense physical exertion, while taking into account for the adjustment of the vent, parameters such as the air temperature or the circulation speed to guarantee an optimal and comfortable ventilation of the air volume between the bezel and the driver's face.
L’évent est orienté directement face à la direction de circulation de l’air arrivant sur la lunette. The vent is oriented directly in front of the direction of air flow entering the bezel.
Ce réglage est particulièrement simple et peut se faire pendant la con duite, puisque le volet coulissant est facilement accessible. This adjustment is particularly simple and can be done while driving, since the sliding shutter is easily accessible.
Suivant une autre caractéristique avantageuse, l’arche médiane formant l’évent transversal comprend une traverse haute et une lame transver sale basse, délimitant l’ouverture de l’évent, les deux extrémités de la traverse haute et celles de la lame basse étant issues des deux boucles et l’arche médiane ayant un guide de réglage de l’ouverture de l’évent, le volet réglable étant formé d’un corps dont le dos est muni d’un organe d’enclipsage accroché au guide de réglage de l’arche médiane ( 10) et permettant le coulissement de réglage du volet. According to another advantageous characteristic, the median arch forming the transverse vent comprises a high cross member and a low transverse blade, delimiting the opening of the vent, the two ends of the upper cross member and those of the lower blade being taken from of the two loops and the middle arch having a guide for adjusting the opening of the vent, the adjustable flap being formed of a body whose back is provided with a clipping member hooked to the guide for adjusting the 'median arch (10) and allowing sliding of the shutter adjustment.
L’assemblage de cette lunette, c’est-à-dire du volet sur le cadre se fait de manière très simple par enclipsage. Cette forme d’accrochage permet le réglage du volet entre les différentes positions par de simples coulisse ments du volet sur l’organe d’enclipsage. The assembly of this bezel, that is to say the shutter on the frame, is done very simply by clipping. This form of attachment allows the shutter to be adjusted between the different positions by simply sliding the shutter on the clipping member.
La circulation d’air arrivant sur la lunette ne risque pas de déplacer le volet puisque celui-ci est réglable dans une direction pratiquement per pendiculaire à la direction de l’air arrivant sur la lunette. The circulation of air arriving on the bezel does not risk moving the shutter since the latter is adjustable in a direction almost perpendicular to the direction of the air arriving on the bezel.
Suivant une caractéristique particulièrement avantageuse pour le ré glage de l’évent, le guide de réglage est formé de deux tiges reliant la traverse haute à la lame basse en barrant l’ouverture de l’évent selon la direction de réglage, l’organe d’enclipsage étant une barrette reliée au dos du corps du volet par deux pieds laissant un intervalle égal à l’épaisseur des deux tiges, la barrette est terminée par deux becs avec une rampe pour faire passer la barrette avec ses deux becs entre les deux tiges et s’accrocher derrière celles-ci, la barrette ayant une boucle souple lui confèrent 1’élasticité transversale nécessaire au passage des becs entre les deux tiges longueur de la barrette entre ses becs étant, à l’état détendu, supérieure à l’écartement des deux tiges. According to a particularly advantageous feature for the adjustment of the vent, the adjustment guide is formed of two rods connecting the upper cross member to the lower blade by blocking the opening of the vent in the direction of adjustment, the member of 'clip being a bar connected to the back of the shutter body by two feet leaving an interval equal to the thickness of the two rods, the bar is terminated by two nozzles with a ramp to pass the bar with its two nozzles between the two rods and hang behind them, the bar having a flexible loop gives it elasticity transverse necessary for the passage of the beaks between the two rods, the length of the bar between its beaks being, in the relaxed state, greater than the spacing of the two rods.
Suivant une caractéristique particulièrement intéressante la face avant de la traverse a au moins un bossage et le dos du volet venant au con tact de la face avant de la traverse à au moins un bossage complémen taire, dans une position homologue, de façon à définir au moins deux positions de retenue du corps de volet par rapport à la traverse, ces po sitions constituant des positions de réglage de l’ouverture de l’évent. According to a particularly interesting feature, the front face of the cross member has at least one boss and the back of the shutter coming into contact with the front face of the cross member has at least one additional boss, in a corresponding position, so as to define at least one additional boss. at least two retaining positions of the shutter body relative to the cross member, these positions constituting positions for adjusting the opening of the vent.
Ces organes de retenue constitués par les bossages du cadre et du volet permettent de maintenir efficacement le volet dans la position réglée, malgré les secousses violentes auxquelles la lunette peut être exposée. These retaining members formed by the bosses of the frame and of the shutter make it possible to effectively maintain the shutter in the adjusted position, despite the violent jolts to which the bezel may be exposed.
Ces bossages permettent également à l’utilisateur de repérer de manière haptique les différentes positions de réglage. Ces bossages sont notam ment en forme de nervures orientées transversalement. These bosses also allow the user to haptically locate the different adjustment positions. These bosses are in particular in the form of ribs oriented transversely.
Selon une réalisation avantageuse, le guide de réglage le guide de ré glage est formé de deux coulisses munies de reliefs et l’organe d’enclip- sage est formé par deux broches au dos de la plaquette formant le corps du volet, les broches enclipsées chacune dans l’une des coulisses, étant retenues dans la position de réglage en coulissement par les reliefs of frant une résistance au passage des broches. According to an advantageous embodiment, the adjustment guide the adjustment guide is formed by two slides provided with reliefs and the clipping member is formed by two pins on the back of the plate forming the body of the shutter, the pins clipped. each in one of the slides, being retained in the sliding adjustment position by the reliefs of frant resistance to the passage of the pins.
Cette réalisation du guide de réglage et du volet constitue une solution particulièrement simple par la forme des moyens de guidage et de ré glage entre le volet et l’arche médiane pour régler efficacement l’ouver ture de l’évent. This realization of the adjustment guide and the shutter is a particularly simple solution due to the shape of the guide and adjustment means between the shutter and the median arch to effectively adjust the opening of the vent.
De façon avantageuse, le volet a une surface d’aspérité ou de relief telle que, par exemple, l’impression d’une marque ou d’une indication en re lief permettant de manœuvrer facilement le volet avec la main gantée du conducteur. Advantageously, the flap has a rough or raised surface such as, for example, the printing of a mark or an indication in relief allowing the flap to be easily operated with the gloved hand of the driver.
Suivant une autre caractéristique avantageuse, la boucle rejoint l’arche médiane par un segment haut d’épaisseur réduite formant un décroche ment un palier et le segment bas a également une section réduite du côté du montant avec un palier aligné sur le palier du segment haut pour former l’axe de pivotement d’un arceau dont les extrémités des branches munies de pivots engagés dans le palier respectif de la boucle correspondante. Cette forme de réalisation des arceaux pour l’accro chage des deux extrémités du bandeau de la lunette permet d’intégrer les arceaux dans le contour général de la lunette ce qui est avantageux à la fois pour ne pas créer de différences de relief par lesquelles la lu nette pourrait s’accrocher dans certaines conditions d’utilisation. De plus, cela améliore l’effet esthétique de la lunette. According to another advantageous characteristic, the loop joins the median arch by a high segment of reduced thickness forming a landing and the lower segment also has a reduced section on the side of the upright with a bearing aligned with the bearing of the upper segment. to form the pivot axis of a hoop whose ends of the branches provided with pivots engaged in the respective bearing of the buckle corresponding. This embodiment of the hoops for hooking the two ends of the band of the bezel makes it possible to integrate the hoops into the general outline of the bezel which is advantageous both so as not to create differences in relief by which the The net read may catch on under certain conditions of use. In addition, it improves the aesthetic effect of the bezel.
Suivant une autre caractéristique avantageuse, le segment bas de la boucle rejoint le côté incliné de la boucle nasale par un évent en forme de fente réalisé dans l’épaisseur augmentée du segment bas. Là encore l’évent latéral au bas de chaque côté de la lunette s’intégre avantageuse ment dans le contour global de la lunette et constitue un point d’aéra tion ou d’entrée d’air supplémentaire de chaque côté du bas de la lunette. According to another advantageous feature, the bottom segment of the loop joins the inclined side of the nasal loop through a slot-shaped vent made in the increased thickness of the bottom segment. Here again the side vent at the bottom of each side of the bezel is advantageously integrated into the overall contour of the bezel and constitutes an additional ventilation or air intake point on each side of the bottom of the bezel. .
Suivant une autre caractéristique, l’évent de l’arche médiane et les évents des segments bas sont barrés par une grille. Cette grille est, par exemple, constituée par un voile muni de petites perforations qui évitent le passage de petits objets transportés par le vent de circulation tels que des grains de poussière ou des insectes. Sans pour autant nuire à l’effi cacité de la ventilation. According to another feature, the vent of the middle arch and the vents of the lower segments are blocked by a grid. This grid is, for example, constituted by a veil provided with small perforations which prevent the passage of small objects carried by the circulating wind such as grains of dust or insects. Without compromising the efficiency of ventilation.
Suivant une autre caractéristique, le cadre a un dos formé d’un contour avant relié par une bande intermédiaire au contour arrière, cette bande étant en forme de treillis sur le dessus et les côtés et sur une partie du retour de chaque côté vers la voûte nasale. According to another characteristic, the frame has a back formed by a front contour connected by an intermediate strip to the rear contour, this strip being in the form of a lattice on the top and the sides and on a part of the return on each side towards the arch. nasal.
Cette forme de contour a l’avantage de constituer une interface souple entre l’avant de la lunette avec son écran et le visage du conducteur. La jonction du contour avant et de la bande forme une rainure pour l’ac crochage du dos souple à une nervure en relief du cadre. Le dos est ainsi simplement enclipsable dans le cadre. Cela permet, le cas échéant, de remplacer facilement le dos qui est une pièce d’usure. Cela permet également d’adapter plus précisément la forme du dos de la lunette à la forme du visage. This contour shape has the advantage of providing a flexible interface between the front of the bezel with its screen and the driver's face. The junction of the front contour and the band forms a groove for hooking the flexible back to a raised rib of the frame. The back is thus simply clipped into the frame. This allows, if necessary, to easily replace the back which is a wearing part. This also allows the shape of the back of the glasses to be more precisely adapted to the shape of the face.
Suivant une autre caractéristique avantageuse, la bande intermédiaire rejoint le contour arrière par une surface continue formant une voûte nasale souple dans le prolongement de la voûte nasale du cadre. According to another advantageous characteristic, the intermediate band joins the rear contour by a continuous surface forming a flexible nasal arch in the extension of the nasal arch of the frame.
Ainsi, en résumé, la lunette selon l’invention est une réalisation particu lièrement simple puisqu’elle est composée de différents éléments qui sont fabriqués séparément pour être reliés les uns aux autres par des liaisons par la forme tel que l’enclipsage permettant de réaliser les diffé rents éléments avec des matériaux de caractéristiques appropriées à chaque fonction. La lunette a l’avantage d’offrir une excellente ventila tion du volume entre la lunette et le visage grâce au réglage de l’arrivée de l’air en fonction des paramètres extérieurs. Thus, in summary, the bezel according to the invention is a particularly simple realization since it is composed of different elements which are manufactured separately to be connected to each other by connections by the form such as the clipping allowing to achieve the different elements with materials of suitable characteristics each function. The glasses have the advantage of offering excellent ventilation of the volume between the glasses and the face thanks to the adjustment of the air inlet according to the external parameters.

DESCRIPTION DETAILLEE D’EXEMPLES DE REALISATION DETAILED DESCRIPTION OF EXAMPLES OF IMPLEMENTATION
Selon la figure 1 qui montre un premier mode de réalisation, la lunette de protection se compose d’un cadre 100 recevant un écran 120 et muni latéralement de deux arceaux 130 pour fixer les extrémités du bandeau de la lunette. According to Figure 1 which shows a first embodiment, the protective glasses consists of a frame 100 receiving a screen 120 and laterally provided with two arches 130 for fixing the ends of the band of the glasses.
Le dos 1 10 du cadre 100 est un contour souple avec des ouvertures pour venir au contact du visage, les ouvertures assurant la ventilation du volume compris entre la lunette et le visage. The back 110 of the frame 100 is a flexible outline with openings to come into contact with the face, the openings ensuring ventilation of the volume between the bezel and the face.
La lunette est symétrique selon le plan de symétrie PVM qui est son plan vertical médian. Chaque arceau 130 se compose d’une branche haute 51, d’une tige 52 pour la fixation d’une extrémité du bandeau non représenté et d’une branche basse 53. Les extrémités des branches 51, 53 sont fixées au cadre 1 1 par des points de fixation 54 formant des articulations de pivotement. The bezel is symmetrical along the PVM plane of symmetry, which is its median vertical plane. Each hoop 130 consists of a high branch 51, a rod 52 for fixing one end of the band, not shown, and a low branch 53. The ends of the branches 51, 53 are fixed to the frame 1 1 by fixing points 54 forming pivot joints.
Les arceaux 130 sont dégagés du contour des côtés du cadre 100 pour pouvoir pivoter librement sans s’accrocher aux côtés du cadre 100. The hoops 130 are released from the outline of the sides of the frame 100 so that they can pivot freely without snagging the sides of the frame 100.
Les points de fixation 54 se situent sensiblement près du milieu de chaque moitié en haut et en bas du cadre pour que la traction exercée par le bandeau puisse bien appliquer la lunette sur le visage. The attachment points 54 are located substantially near the middle of each half at the top and bottom of the frame so that the traction exerted by the band can properly apply the glasses to the face.
Dans cette forme de réalisation, les branches 51, 53 des deux arceaux 130 s’inscrivent bien dans le contour haut et bas du cadre 100. In this embodiment, the branches 51, 53 of the two arches 130 fit well into the top and bottom contour of the frame 100.
Le cadre 100 sera décrit ci-après, de façon plus détaillée à l’aide de la fi gure 2. The frame 100 will be described below, in more detail with the aid of Figure 2.
Le cadre 100 se compose en général de façon symétrique par rapport au plan vertical médian PVM, de l’arche médiane 10 en partie haute et de la voûte nasale 40 en partie médiane basse. La partie haute du cadre y compris l’arche 10 se situe au niveau du front et la voûte nasale 40 coiffe le nez. La voûte 40 se compose d’un dessus 41 bordé par deux cô tés 42 inclinés. The frame 100 is generally made up symmetrically with respect to the vertical median plane PVM, of the median arch 10 in the upper part and of the nasal arch 40 in the lower median part. The upper part of the frame including the arch 10 is located at the level of the forehead and the nasal arch 40 covers the nose. The vault 40 consists of a top 41 bordered by two inclined sides 42.
Sur les côtés, le cadre 100 a deux boucles 30 en forme de U couché composée chacune d’un segment haut 31, d’un segment intermédiaire montant 32 et d’un segment bas 33. Le segment haut 31 est relié à l’arche médiane 10 et le segment bas 33 est relié au côté incliné 42 de la voûte nasale 40. On the sides, the frame 100 has two loops 30 in the shape of a lying U each composed of a top segment 31, an intermediate segment rising 32 and a bottom segment 33. The upper segment 31 is connected to the middle arch 10 and the lower segment 33 is connected to the inclined side 42 of the nasal arch 40.
Les boucles 30 en U, ont une forme trapézoïdale. Le segment haut 31 de la boucle 30 de part et d’autre de l’arche 10 a une partie relevée 31a for mant ensuite vers le côté un décrochement 31c et une surface de jonc tion réduite 31b recevant l’extrémité de la branche haute 51 d’un arceau 130. L’autre branche 53 de l’arceau est assemblée au segment bas 33 de la boucle 30 dans une partie 31b également de hauteur ré duite, de façon à intégrer chaque fois la jonction de la branche basse 53 de l’arceau 130 et du cadre 100 dans la section globale du cordon for mant le cadre 100. Cette partie réduite 33b rejoint la partie 33a par un décrochement 33c. The U-shaped loops 30 have a trapezoidal shape. The top segment 31 of the loop 30 on either side of the arch 10 has a raised part 31a then forming towards the side a step 31c and a reduced junction surface 31b receiving the end of the high branch 51 a hoop 130. The other branch 53 of the hoop is assembled to the lower segment 33 of the loop 30 in a part 31b also of reduced height, so as to integrate each time the junction of the lower branch 53 of the 'hoop 130 and of the frame 100 in the overall section of the cord forming the frame 100. This reduced part 33b joins the part 33a by a step 33c.
L’arche médiane 10 forme un évent 140 muni d’un volet réglable 150, coulissant dans la direction de réglage D (direction "verticale"). The middle arch 10 forms a vent 140 provided with an adjustable shutter 150, sliding in the adjustment direction D ("vertical" direction).
La figure 2 montre le cadre 100 et le volet 150 en vue éclatée permet tant de mieux voir la structure du cadre sans son dos 1 10 et sans les arceaux 130. Figure 2 shows the frame 100 and the shutter 150 in exploded view allows both to better see the structure of the frame without its back 1 10 and without the hoops 130.
Ainsi cette vue met en évidence les différentes parties du cadre 100 et notamment la forme des deux boucles 30, symétriques par rapport au plan médian PVM (figure 1). Thus this view highlights the different parts of the frame 100 and in particular the shape of the two loops 30, symmetrical with respect to the median plane PVM (FIG. 1).
L’arche médiane 10 a une hauteur plus importante que la partie 31a du segment haut 31 de chaque boucle 30 pour réaliser l’évent 140. The middle arch 10 has a greater height than the part 31a of the top segment 31 of each loop 30 to achieve the vent 140.
Le volet 150 est présenté dans son orientation face à l’arche médiane 10 et des lignes en pointillés montrent la direction de l’assemblage du volet 150 à l’arche médiane 10 pour compléter l’évent 140. The shutter 150 is shown in its orientation facing the middle arch 10 and dashed lines show the direction of assembly of the shutter 150 to the middle arch 10 to complete the vent 140.
La figure 3 dans ses parties 3A, 3B montre en perspective l’arche mé diane du cadre 100 ; le volet 150 a été retourné pour montrer son côté arrière qui sera tourné face à la traverse 1 1. Figure 3 in its parts 3A, 3B shows in perspective the middle arch of the frame 100; the shutter 150 has been turned over to show its rear side which will be turned facing the crossmember 1 1.
L’évent 140 de l’arche médiane 10 selon la figure 3 A est formé par la traverse haute 1 1 rejoignant les parties 31a du segment haut 31 de chaque boucle 30 en même temps que les extrémités 12b de la lame basse 12. The vent 140 of the middle arch 10 according to Figure 3A is formed by the top cross member 11 joining the parts 31a of the top segment 31 of each loop 30 at the same time as the ends 12b of the bottom blade 12.
La lame basse 12 suit en parallèle le tracé de la traverse 1 1 et remonte par ses extrémités 12b sur les côtés des parties 31a ; l’ensemble en vue de face a une forme trapézoïdale. La traverse haute 1 1 n’occupe pas toute l’épaisseur du cadre définie par la lame 12 et les parties 31a laissant un volume libre devant sa face avant 1 la et le dessus 12a de la lame 12. The low blade 12 follows in parallel the path of the cross member 1 1 and goes up by its ends 12b on the sides of the parts 31a; the whole in front view has a trapezoidal shape. The high cross member 11 does not occupy the entire thickness of the frame defined by the blade 12 and the parts 31a leaving a free space in front of its front face 11a and the top 12a of the blade 12.
La traverse 1 1 laisse un intervalle au-dessus de la lame 1 1 formant deux passages 14 délimités par des guides d’enclipsage et de réglage 13 du volet 150. The crosspiece 1 1 leaves an interval above the blade 1 1 forming two passages 14 delimited by clips 13 and adjustment of the shutter 150.
Les guides 13 ( 13a, b) en forme de tige laissent entre eux un passage central 15 à double fonction, celle de faire partie de l’évent et celle de permettre l’enclipsage du volet coulissant 150. The rod-shaped guides 13 (13a, b) leave between them a central passage 15 with a dual function, that of being part of the vent and that of allowing the sliding shutter 150 to be clipped.
Le volet coulissant 150 est constitué d’une plaquette 20 formant le corps de volet. Cette plaquette 20 a la forme d’un trapèze s’inscrivant dans le contour trapézoïdal courbe du volume libre devant la traverse 1 1 au-dessus de la lame 12. The sliding shutter 150 consists of a plate 20 forming the shutter body. This plate 20 has the shape of a trapezoid forming part of the curved trapezoidal contour of the free volume in front of the cross member 1 1 above the blade 12.
Le dos 20a du corps 20 qui suit la forme de la traverse 1 1 (ici une forme bombée) est muni d’une barrette enclipsable 21 formant un organe d’enclipsage relié au corps 20 par deux pieds 22. The back 20a of the body 20 which follows the shape of the crosspiece 11 (here a convex shape) is provided with a clip-on bar 21 forming a clipping member connected to the body 20 by two feet 22.
La barrette 21 a une ondulation souple 23 entre les deux pieds 22 et se termine, dans la direction transversale au-delà des pieds 22, par des becs de retenue 24. The bar 21 has a flexible corrugation 23 between the two feet 22 and ends, in the transverse direction beyond the feet 22, with retaining spouts 24.
Chaque bec 24 a une rampe 241 tournée vers le dos 20a et une facette 24b définissant, avec le corps du volet 20 un intervalle I correspondant sensiblement à l’épaisseur des tiges 13a, 13b. Each spout 24 has a ramp 241 facing the back 20a and a facet 24b defining, with the body of the shutter 20, an interval I corresponding substantially to the thickness of the rods 13a, 13b.
Le dos 20adu corps de volet 20 a également des bossages 26 (bossage haut 26a et bossage bas 26b) pour coopérer avec des formes complé mentaires 16 de la face avant 1 la de la traverse 1 1 et permettre de ré gler trois positions du corps de volet 20. The back 20adu shutter body 20 also has bosses 26 (top boss 26a and bottom boss 26b) to cooperate with complementary shapes 16 of the front face 11a of the crosspiece 1 1 and allow three positions of the body to be adjusted. shutter 20.
Selon l’exemple représenté, les bossages 26, 26a, 26b sont des reliefs en forme de barrette transversale et le bossage 16 de la face avant 1 la de la traverse l i a une forme analogue et dans une position homologue à celle des bossages 26a, 26b pour réaliser les positions de réglage de l’évent 30 comme cela sera décrit à l’aide des figures 5a-5c et des fi gures 6a-6c. According to the example shown, the bosses 26, 26a, 26b are reliefs in the form of a transverse bar and the boss 16 of the front face 1a of the cross member has a similar shape and in a position homologous to that of the bosses 26a, 26b to achieve the adjustment positions of the vent 30 as will be described with the aid of Figures 5a-5c and Figures 6a-6c.
Le volet 150 est accroché de façon réglable en coulissement comme cela sera décrit ci-après, à l’aide des figures 4A, 4B. La figure 4A est une vue en coupe de l’arche médiane 10 sous la tra verse 1 1 ; cette vue en coupe passe par les tiges 13a, 13b et montre ainsi les intervalles formés par les passages 14, 15. la figure 4B est une vue en coupe horizontale identique à celle de la fi gure 4A mais de l’évent 140 avec le volet 150 mis en place par enclip- sage. The shutter 150 is hooked in an adjustable sliding manner as will be described below, using FIGS. 4A, 4B. Figure 4A is a sectional view of the median arch 10 under the traverses 1 1; this sectional view passes through the rods 13a, 13b and thus shows the intervals formed by the passages 14, 15. FIG. 4B is a horizontal sectional view identical to that of FIG. 4A but of the vent 140 with the shutter 150 put in place by snapping.
Pour relier le volet 150 au cadre 100, on le présente devant la face l ia de la traverse 1 1 et plus précisément avec son organe d’enclipsage 21 devant le passage central 15 et les pieds 13a, 13b. To connect the shutter 150 to the frame 100, it is presented in front of the face l ia of the crosspiece 11 and more precisely with its clipping member 21 in front of the central passage 15 and the feet 13a, 13b.
Les rampes 24a se glissent alors entre les tiges 13a, 13b en déformant les pieds 22 grâce à l’ondulation souple 23 qui repousse ensuite élasti- quement les becs 24 lorsque ceux-ci sont arrivés derrière les guides 13a, 13b pour s’y accrocher par les surfaces d’appui formées par les fa cettes 24b. The ramps 24a then slide between the rods 13a, 13b, deforming the feet 22 thanks to the flexible corrugation 23 which then elastically pushes back the nozzles 24 when the latter have arrived behind the guides 13a, 13b in order to cling to them. by the bearing surfaces formed by the facets 24b.
Ainsi accroché, le volet 150 peut coulisser le long des guides 13a, 13b dans la direction perpendiculaire au plan de la figure 4B, c’est-à-dire selon la direction D (figure 1). Thus hung, the shutter 150 can slide along the guides 13a, 13b in the direction perpendicular to the plane of Figure 4B, that is to say in direction D (Figure 1).
Les figures 5A-5C montrent la position du corps 20 du volet 150 par rapport à la traverse haute 1 1 et la lame basse 12. Figures 5A-5C show the position of the body 20 of the shutter 150 relative to the top cross member 1 1 and the bottom blade 12.
Les figures 5A-5C sont des vues en coupe selon le plan PVM (figure 1) laissant apparaître derrière le plan de coupe, la forme du corps 20 et de la lame 12. Les lignes représentées sont dues au cintrage des éléments. FIGS. 5A-5C are sectional views along the PVM plane (FIG. 1) showing behind the section plane, the shape of the body 20 and of the blade 12. The lines shown are due to the bending of the elements.
La figure 5A montre le corps 20 en position haute dégageant complète ment les passages 14, 15. Le corps 20 est en appui par son bossage bas 26b au-dessus du bossage 16 de la traverse 1 1 en étant ainsi retenu. Figure 5A shows the body 20 in the high position completely releasing the passages 14, 15. The body 20 is supported by its low boss 26b above the boss 16 of the cross member 1 1 while being thus retained.
La figure 5B montre le corps de volet 20 en position intermédiaire : les bossages haut 26a et bas 26b sont à cheval sur le bossage 16. Les pas sages 14, 15 sont alors partiellement fermés. FIG. 5B shows the shutter body 20 in an intermediate position: the top 26a and bottom 26b bosses straddle the boss 16. The wise steps 14, 15 are then partially closed.
La figure 5C montre le corps de volet 20 complètement abaissé. Le bos sage haut 26a est retenu sous le bossage 16. Les passages 14, 15 sont complètement fermés. Figure 5C shows the shutter body 20 fully lowered. The top sage bos 26a is retained under the boss 16. The passages 14, 15 are completely closed.
Le mouvement du volet 20 d’une position à l’autre se fait en poussant suffisamment sur le volet 20 dans la direction D pour le déformer par son élasticité et passer sur le bossage 16 par l’un ou les deux bossages 26a, 26b. Ce mouvement avec déformation élastique du corps de volet 20 est rendu possible par la position des bossages 26a, 26b sur les deux côtés du corps de volet 20 au-delà des pieds 22 et de la tête 24 de la barrette 21. The movement of the shutter 20 from one position to the other is effected by pushing the shutter 20 sufficiently in the direction D to deform it by its elasticity and pass over the boss 16 through one or both bosses 26a, 26b. This movement with elastic deformation of the shutter body 20 is made possible by the position of the bosses 26a, 26b on both sides of the shutter body 20 beyond the feet 22 and the head 24 of the bar 21.
Les figures 6A-6C sont des vues en coupe simplifiées ne montrant que la surface coupée des différents éléments en mettant ainsi clairement en évidence raccrochage du corps de volet 20 par ses bossages 26a, 26b au bossage 16 de la traverse haute 1 1. Figures 6A-6C are simplified sectional views showing only the cut surface of the various elements, thus clearly showing the attachment of the shutter body 20 by its bosses 26a, 26b to the boss 16 of the top cross member 1 1.
Les figures 7A-7B sont des vues en perspective complètes de la lunette 100 pour le volet 150 en position d’ouverture complète (figure 7A) et de fermeture complète (figure 7B). Figures 7A-7B are full perspective views of the bezel 100 for the shutter 150 in the fully open (Figure 7A) and fully closed (Figure 7B) position.
La figure 7A correspond à la position du volet 150 selon les vues en coupe des figures 5A, 5B. La figure 7B correspond à la position du volet 150 des vues en coupe des figures 5C, 6C. FIG. 7A corresponds to the position of the shutter 150 according to the sectional views of FIGS. 5A, 5B. FIG. 7B corresponds to the position of the shutter 150 of the sectional views of FIGS. 5C, 6C.
Selon les figures 8, 8A, le second mode de réalisation de la lunette LA se compose d’un cadre 100A auquel est fixé un dos 1 10A, souple pour l’appui sur le visage. According to Figures 8, 8A, the second embodiment of the LA telescope consists of a frame 100A to which is attached a back 110A, flexible for support on the face.
Le cadre 100A, muni d’un écran 120A porte deux arceaux 130A reliés de façon pivotante au cadre 100A et servant à la fixation des extrémités du bandeau non représenté. The frame 100A, provided with a screen 120A carries two hoops 130A pivotally connected to the frame 100A and serving for fixing the ends of the strip, not shown.
Le haut du cadre 100A comporte un évent 14 IA équipé d’un volet 150A pour régler l’ouverture de l’évent entre sa position complètement ou verte jusqu’à sa position complètement fermée. Le bas du cadre 100A a une voûte nasale 240 munie d’un prolongement 260 enclipsé. The top of the 100A frame features a 14 IA vent fitted with a 150A shutter to adjust the vent opening from its full or green position to its fully closed position. The bottom of the frame 100A has a nasal arch 240 with a snap-on extension 260.
Les différents composants de la lunette LA seront détaillés ci-après. The various components of the LA telescope will be detailed below.
Selon les figures 8, 9, 9A, 10, 10A, le cadre 100A se compose d’une arche médiane 210 formée d’une traverse haute 21 1 avec une face avant 21 la et d’une lame basse 212 avec un dessus 212a laissant le passage 214 transversal, ouvert, muni d’une grille 215. According to Figures 8, 9, 9A, 10, 10A, the frame 100A consists of a median arch 210 formed of a high cross member 21 1 with a front face 21 la and a low blade 212 with a top 212a leaving the transverse passage 214, open, provided with a grid 215.
Le cadre 100A, symétrique par rapport au plan médian, se compose de deux boucles 230 en forme de U couché, chaque boucle étant composée d’un segment haut 231, d’un segment intermédiaire 232, montant et d’un segment bas 233. The frame 100A, symmetrical with respect to the median plane, consists of two loops 230 in the shape of a lying U, each loop being composed of a high segment 231, an intermediate segment 232, rising and a low segment 233.
Le segment haut 231 rejoint l’extrémité de l’arche médiane 210 en réali sant un décrochement 23 IC entre la partie relevée 231a et la partie réduite 231b (hauteur réduite). Cette dernière se prolonge sur tout le segment haut 231 jusqu’au montant 232. The high segment 231 joins the end of the median arch 210 by making a step 23 IC between the raised part 231a and the part reduced 231b (reduced height). The latter extends over the entire top segment 231 to the upright 232.
Derrière le décrochement 231c, le cadre a un palier 234 avec un per çage pour recevoir le pivot de l’arceau 130A comme cela sera décrit en suite. Behind the step 231c, the frame has a bearing 234 with a bore to receive the pivot of the hoop 130A as will be described below.
La section de la partie réduite 231b est sensiblement conservée pour le montant 232 rejoignant le segment bas 233, incliné, qui est relié au côté incliné 242 de la voûte nasale 240. The section of the reduced part 231b is substantially retained for the upright 232 joining the lower segment 233, inclined, which is connected to the inclined side 242 of the nasal arch 240.
Sur une partie de sa longueur, près du côté 242, le segment bas 233 augmente de hauteur pour former une ouverture allongée 235 occupée par une grille 236. Derrière cette ouverture 235, dans l’alignement du palier 234 du segment haut, il y a un palier 237 pour former l’axe de pi votement AP pour l’arceau 130A. Along part of its length, near side 242, the low segment 233 increases in height to form an elongated opening 235 occupied by a grid 236. Behind this opening 235, in line with the bearing 234 of the high segment, there is a bearing 237 to form the axis of pi votement AP for the hoop 130A.
Les deux paliers 234, 237 avec leur axe AP apparaissent derrière le cadre en partie gauche aux figures 10, 10A. The two bearings 234, 237 with their axis AP appear behind the frame in the left part in Figures 10, 10A.
La partie médiane basse du cadre 1 10A est occupée par la voûte nasale 240 composée des deux côtés inclinés 242 et du dessus droit 241. The lower middle part of the frame 110A is occupied by the nasal arch 240 composed of the two inclined sides 242 and the right top 241.
En partie haute, l’évent 140A est muni du volet 150A formé d’une pla quette 220 dont le dos 220a (figure 10A) a deux broches 221 d’enclip- sage, avec une tête de champignon pour s’engager dans une coulisse 222 respective réalisée dans la traverse haute 21 1. At the top, the vent 140A is provided with the shutter 150A formed by a plate 220 whose back 220a (FIG. 10A) has two clipping pins 221, with a mushroom head to engage in a slide. 222 respectively made in the top cross member 21 1.
Les deux coulisses 222, d’orientation verticale, en position symétrique, ont des reliefs de retenue 216 pour définir les positions de réglage de la plaquette 220, c’est-à-dire du degré d’ouverture ou de fermeture de l’évent. The two slides 222, vertically oriented, in a symmetrical position, have retaining reliefs 216 to define the adjustment positions of the plate 220, that is to say the degree of opening or closing of the vent. .
Dans la vue de dessus de la figure 10A, le volet 150A est représenté au- dessus de l’évent 140A et non accroché aux coulisses 222a. In the top view of Figure 10A, the shutter 150A is shown above the vent 140A and not hooked to the slides 222a.
Le corps 220 du volet a une épaisseur inférieure à la profondeur du vo lume libre devant la traverse 210. La face avant 220b du corps 220 est munie de reliefs de préhension 223, par exemple, la marque en relief du produit pour faciliter au conducteur la manœuvre de réglage du volet 150A avec sa main gantée. The body 220 of the shutter has a thickness less than the depth of the free space in front of the crosspiece 210. The front face 220b of the body 220 is provided with gripping reliefs 223, for example, the raised mark of the product to facilitate the driver's handling. 150A shutter adjustment maneuver with his gloved hand.
Selon les figures 1 1, 1 IA, 1 IB, le dos 1 10A du cadre 100A est une pièce en matière au moins en partie souple formée d’un contour avant 270 relié à un contour arrière 272 par une bande intermédiaire 271 partiel lement en forme de treillis. According to Figures 1 1, 1 IA, 1 IB, the back 110A of the frame 100A is a part of at least partially flexible material formed of a front contour 270 connected to a rear contour 272 by an intermediate strip 271 partially in the form of a lattice.
Le contour avant 270 suit le contour du cadre 100A et comporte des re liefs pour coopérer avec la forme du cadre pour y être accroché. Le con tour avant 270 forme avec la bande intermédiaire 271 une rainure 273 (figure 1 IA) pour recevoir, un relief en forme de nervure bordant l’inté rieur du cadre 1 10A. The front contour 270 follows the contour of the frame 100A and includes reliefs to cooperate with the shape of the frame to be hung thereon. The front tour 270 forms with the intermediate strip 271 a groove 273 (Figure 1 IA) for receiving a rib-shaped relief bordering the inside of the frame 110A.
Le dos 1 10A comporte également des passages 274 pour les pivots des arceaux 130A. The back 110A also has passages 274 for the pivots of the hoops 130A.
La forme en treillis de la bande intermédiaire 272 donnant la souplesse sur le dessus et les côtés apparaissant clairement aux figures 1 1 et 1 IA. Dans sa partie inférieure, la bande intermédiaire 27 lest continue et dans le prolongement 275 de ce qui correspond à la voûte nasale 240, la bande 271 se rétrécit. The lattice shape of the intermediate strip 272 giving flexibility on the top and the sides clearly appearing in Figures 11 and 1 IA. In its lower part, the intermediate strip 27 continuous ballast and in the extension 275 of what corresponds to the nasal arch 240, the strip 271 narrows.
Le contour arrière 272 est une bande plate formant un appui contre le visage de l’utilisateur. Cette bande s’étend sur le haut et les côtés avec un décrochement 276 dans la partie montante des deux côtés pour for mer un passage d’air latéral. Puis, le contour arrière devient en partie inférieure, une forme continue avec un élargissement muni d’entailles 277, radiales au niveau de la voûte nasale 275 pour s’adapter en sou plesse au visage. The rear contour 272 is a flat band forming a support against the face of the user. This band runs on the top and sides with a cutout 276 in the rising part on both sides to provide a side air passage. Then, the rear contour becomes in the lower part, a continuous shape with an enlargement provided with notches 277, radial at the level of the nasal arch 275 to adapt smoothly to the face.
La figure 12 montre en une vue éclatée, le cadre 100A avec les deux ar ceaux 130A et le prolongement 260. FIG. 12 shows in an exploded view the frame 100A with the two arches 130A and the extension 260.
Chaque arceau 130A est composé d’une branche haute 251 reliée par une branche montante 252 à une branche basse 253. Each hoop 130A is composed of a high branch 251 connected by a rising branch 252 to a low branch 253.
Les branches haute 251 et basse 253 sont en forme de lamelles et la branche montante 252 est en forme de bande couvrant une tige 255 à laquelle on fixe l’extrémité respective du bandeau. The high 251 and low 253 branches are in the form of strips and the rising branch 252 is in the form of a strip covering a rod 255 to which the respective end of the band is fixed.
Les branches 251, 253 se terminent par un pivot 254 qui s’engage dans les paires de palier 234, 237. Branches 251, 253 terminate in a pivot 254 which engages bearing pairs 234, 237.
Le prolongement 260 en forme d’auvent est une pièce à facettes 261, 262 avec des arêtes dans le prolongement de la voûte nasale 240 du cadre 100A, de son dessus 241 et de ses côtés inclinés 242. Le prolongement 260 est muni de languettes de fixation 263 qui s’enga gent et s’accrochent dans des orifices de forme correspondante de la voûte nasale 240 du cadre 100A. The extension 260 in the form of a canopy is a faceted piece 261, 262 with ridges in the extension of the nasal arch 240 of the frame 100A, its top 241 and its inclined sides 242. The extension 260 is provided with fixing tabs 263 which engage and hook into correspondingly shaped orifices of the nasal arch 240 of the frame 100A.
Les figures 13, 13A- 13C sont diverses vues de la lunette complète LA sans le bandeau. Figures 13, 13A-13C are various views of the complete telescope LA without the band.
La vue de la figure 13 met en évidence la forme de l’évent 140A avec son volet 150A ouvert, laissant voir la grille 215. Les ouvertures 235 avec leur grille 236 forment des prises d’air dans la partie inférieure de la lu nette. The view in Figure 13 shows the shape of the vent 140A with its shutter 150A open, showing the grille 215. The openings 235 with their grille 236 form air intakes in the lower part of the net.
Les branches haute et basse 251, 253 des arceaux 130A s’inscrivent dans le contour général du cadre 100A. La vue de face montre aussi le dos 1 10A, ses décrochements 276 et l’élargissement muni d’entailles ra diales 277. The top and bottom legs 251, 253 of the hoops 130A fit into the general outline of the frame 100A. The front view also shows the back 110A, its indentations 276 and the enlargement provided with radical notches 277.
La vue arrière (figure 13 A) montre tout particulièrement le dos 1 1 OA et les arceaux 130A avec la tige respective 253. The rear view (Figure 13A) shows in particular the back 1 1 OA and the hoops 130A with the respective rod 253.
La vue de côté (figure 13B) montre plus particulièrement la position de l’arceau pivotant 130A, venant légèrement devant le contour du cadre 1 10A et la forme de la voûte nasale 240, du prolongement et de la voûte nasale 275 du contour avant du dos. The side view (FIG. 13B) shows more particularly the position of the pivoting arch 130A, coming slightly in front of the outline of the frame 110A and the shape of the nasal arch 240, of the extension and of the nasal arch 275 of the front outline of the back.
