Description

La présente invention concerne une fixation pour visière de casque permettant un basculement de la visière entre une position relevée découvrant le visage et une position rabattue sur le visage.The present invention relates to a helmet visor attachment allowing tilting of the visor between a raised position revealing the face and a folded position on the face.

Les casques avec visière servent à la protection de la tête d'un pilote en cas de choc. Le casque protège le crâne tandis que la visière sert à la protection du visage et au confort visuel en ambiance agressive : vent, poussière, lumière, brouillard,...Helmets with visors are used to protect the head of a pilot in the event of an impact. The helmet protects the skull while the visor serves to protect the face and visual comfort in an aggressive atmosphere: wind, dust, light, fog, ...

Certains casques sont équipés d'un viseur de casque qui est un système optique de projection utilisant la visière rabattue ou plutôt une zone de celle-ci semi-réfléchissante pour afficher aux yeux du pilote des symboles d'aide à la conduite. Ils nécessitent alors un réglage très précis de la position rabattue de la visière par rapport aux autres éléments optiques du viseur portés par le casque.Some helmets are fitted with a helmet visor which is an optical projection system using the folded visor or rather a semi-reflecting area of the latter to display driving assistance symbols to the pilot. They then require very precise adjustment of the folded position of the visor with respect to the other optical elements of the viewfinder carried by the helmet.

La présente invention a pour but de réaliser une fixation articulée d'une visière sur un casque autorisant un basculement de la visière entre une position relevée et une position rabattue précise et reproductible.The present invention aims to achieve an articulated fixing of a visor on a helmet allowing tilting of the visor between a raised position and a folded position precise and reproducible.

Elle a également pour but une fixation articulée d'une visière sur un casque permettant un ajustement fin, selon les trois axes hauteur, largeur et profondeur, du positionnement par rapport au casque de la visière rabattue.It also aims at an articulated fixing of a visor on a helmet allowing a fine adjustment, according to the three axes height, width and depth, of the positioning relative to the helmet of the folded visor.

Elle a aussi pour but une fixation articulée d'une visière sur un casque qui soit d'une réalisation à la fois simple et peu coûteuse.It also aims at an articulated fixing of a visor on a helmet which is of an embodiment both simple and inexpensive.

Elle a pour objet un dispositif de fixation articulée d'une visière sur un casque comportant deux articulations à pivot attachant les côtés de la visière aux parois latérales du casque. Ces articulations comportent chacune deux pièces, l'une fixée au casque, l'autre fixée à la visière, pivotant l'une par rapport à l'autre autour d'un axe de pivot avec des surfaces annulaires en contact dites portées. L'une d'entre elles au moins comporte un mécanisme de blocage par encliquetage sur une position particulière correspondant à la position rabattue de la visière et des moyens de déverrouillage actionnables à volonté pour relâcher le mécanisme de blocage.It relates to an articulated fixing device for a visor on a helmet comprising two pivot joints attaching the sides of the visor to the side walls of the helmet. These articulations each comprise two parts, one fixed to the helmet, the other fixed to the visor, pivoting one relative to the other about a pivot axis with annular surfaces in contact said to be worn. At least one of them comprises a locking mechanism by snap-fastening in a particular position corresponding to the folded position of the visor and unlocking means which can be actuated at will to release the locking mechanism.

Le mécanisme de blocage est constitué d'une rainure diamétrale pratiquée dans l'une des portées dite portée femelle et d'une clavette aux dimensions de la rainure montée élastiquement en relief sur l'autre portée dite portée mâle et escamotable dans cette dernière. Les moyens de déverrouillage comportent un bouton poussoir à tirette centrale qui pénètre dans l'axe creux du pivot au travers de la pièce pivotante supportant la portée femelle, et qui maintient la clavette fixée transversalement à son extrémité au travers d'une ouverture oblongue de l'axe du pivot, et un ressort de rappel agissant sur le bouton poussoir de manière à extraire sa tirette de l'axe creux du pivot et par conséquent à plaquer la clavette sur la portée femelle.The blocking mechanism consists of a diametrical groove formed in one of the so-called female bearing surfaces and of a key with the dimensions of the groove mounted elastically in relief on the other so-called male bearing surface and retractable therein. The unlocking means comprise a push button with central pull which penetrates into the hollow axis of the pivot through the pivoting part supporting the female bearing, and which keeps the key fixed transversely at its end through an oblong opening of the 'axis of the pivot, and a return spring acting on the push button so as to extract its zipper from the hollow axis of the pivot and therefore to press the key on the female seat.

Avantageusement, l'une au moins des articulations comporte une manette surmontant la pièce pivotante fixée à la visière et permettant de rabattre la visière sans avoir à la toucher.Advantageously, at least one of the articulations comprises a lever surmounting the pivoting part fixed to the visor and allowing the visor to be folded down without having to touch it.

Avantageusement, l'une au moins des articulations est munie de moyens de rappel élastique tendant à rappeler la visière en position relevée.Advantageously, at least one of the articulations is provided with elastic return means tending to return the visor to the raised position.

Avantageusement, les deux articulations comportent des cales d'épaisseur pelables disposées sur l'axe de pivot de part et d'autre de la pièce pivotante fixée à la visière permettant un réglage transversal fin de la position de la visière par rapport au casque.Advantageously, the two articulations comprise peelable shims arranged on the pivot axis on either side of the pivoting part fixed to the visor allowing fine transverse adjustment of the position of the visor relative to the helmet.

Avantageusement, les articulations ont leur pièce pivotante fixée à la visière attachée à la visière par l'intermédiaire d'une patte intercalaire à laquelle elle est assemblée par boulonnage de deux brides plates percées de trous oblongs permettant un réglage fin en hauteur et en profondeur de la position de la visière par rapport au casque lorsqu'elle est rabattue.Advantageously, the joints have their pivoting part fixed to the visor attached to the visor by means of an intermediate tab to which it is assembled by bolting two flat flanges pierced with oblong holes allowing fine adjustment in height and depth of the position of the visor relative to the helmet when it is folded down.

D'autres caractéristiques et avantages de l'invention ressortiront de la description d'un mode de réalisation donné à titre d'exemple. Cette description sera faite ci-après en regard du dessin dans lequel :

  • une figure 1 représente un casque de pilote équipé d'un dispositif de fixation de visière selon l'invention ;
  • une figure 2 représente en perspective une platine support de viseur de casque qui est destinée à être attachée sur l'extérieur de la coque d'un casque et sur laquelle sont fixées les articulations du dispositif de fixation de visière, l'une d'entre elles étant vue démontée ;
  • une figure 3 représente en coupe une articulation du dispositif de fixation de visière ; et
  • une figure 4 est une vue d'une articulation du dispositif de fixation de visière équipée d'un ressort de traction permettant de rappeler la visière en position relevée.
Other characteristics and advantages of the invention will emerge from the description of an embodiment given by way of example. This description will be made below with reference to the drawing in which:
  • FIG. 1 represents a pilot helmet fitted with a visor fixing device according to the invention;
  • 2 shows in perspective a helmet visor support plate which is intended to be attached to the outside of the shell of a helmet and on which are fixed the joints of the visor fixing device, one of they being seen dismantled;
  • Figure 3 shows in section an articulation of the visor fixing device; and
  • Figure 4 is a view of a hinge of the visor fixing device equipped with a tension spring for returning the visor in the raised position.

Le dispositif de fixation articulée qui va être décrit sert à l'attache d'une visière sur un casque de pilote prévu pour être équipé d'un viseur de casque.The articulated fixing device which will be described is used for attaching a visor to a pilot helmet intended to be equipped with a helmet visor.

Le casque lui-même comporte une coque 1 de protection enveloppant le crâne à l'exception du visage. Cette coque 1 est surmontée d'une platine 2 en forme de calotte qui est recouverte d'un capotage 55 et qui supporte le tube générateur d'image et les éléments du système optique du viseur de casque projetant l'image du tube générateur d'image sur une zone semi-réfléchissante de la visière. La platine 2 est fixée sur le dessus de la coque 1 du casque grâce à des pattes de fixations boulonnées, un système de trous oblongs permettant d'ajuster la position relative de la calotte 2 par rapport à la coque 1 pour régler la position du viseur de casque par rapport aux yeux du porteur du casque. Elle présente deux pattes latérales 3 qui descendent le long de la coque 1 du casque à hauteur des tempes et portent les articulations 4 du dispositif de fixation articulée de la visière 5.The helmet itself comprises a protective shell 1 enveloping the skull with the exception of the face. This shell 1 is surmounted by a plate 2 in the form of a cap which is covered with a cover 55 and which supports the image generator tube and the elements of the optical system of the helmet viewfinder projecting the image of the tube generating image on a semi-reflecting area of the visor. The plate 2 is fixed on the top of the shell 1 of the helmet by means of bolted fixing lugs, a system of oblong holes making it possible to adjust the relative position of the cap 2 relative to the shell 1 to adjust the position of the viewfinder helmet compared to the helmet wearer's eyes. It has two lateral tabs 3 which descend along the shell 1 of the helmet at the level of the temples and carry the articulations 4 of the articulated fixing device of the visor 5.

La fixation de la visière 5 à la platine 2 et non à la coque 1 du casque permet de réunir en un ensemble à part les différents éléments du viseur de casque dont fait partie une zone semi-réfléchissante de la visière. Cela facilite les réglages des positionnements respectifs des éléments du système optique de projection du viseur de casque, permet de s'affranchir des problèmes posés par le manque de rigidité de la coque 1 du casque et simplifie la maintenance du viseur de casque.The attachment of the visor 5 to the plate 2 and not to the shell 1 of the helmet makes it possible to bring together in a separate set the different elements of the helmet viewfinder which includes a semi-reflecting area of the visor. This facilitates the adjustments of the respective positions of the elements of the helmet visor projection optical system, makes it possible to overcome the problems posed by the lack of rigidity of the shell 1 of the helmet and simplifies the maintenance of the helmet visor.

Chaque patte latérale 3 de la platine 2 porte à son extrémité une articulation 4 à pivot horizontal. Elle se termine, sensiblement à la verticale, par une oreille 10 qui forme une première pièce pivotante d'articulation solidaire du casque. Cette oreille 10 est percée d'un trou 11 pour un axe de pivot horizontal 12 présentant une tête circulaire aplatie 13 prolongée par une tige creuse 14. L'axe de pivot 12 est enfilé dans le trou 11 de l'oreille 10 par l'intérieur. Sa tête circulaire aplatie 13 vient se plaquer contre la paroi arrière de l'oreille 10 tandis que sa tige 14 dépasse à l'horizontal de la paroi avant de l'oreille 10. La tête circulaire aplatie 13 de l'axe de pivot 12 est percée à sa périphérie de trous 15 permettant sa fixation par vis à la patte 3 de la platine 2. La paroi avant de l'oreille 10 prend, autour de la base de la tige 14 de l'axe de pivot 12, la forme d'un plateau annulaire 16 servant de portée à l'articulation.Each lateral tab 3 of the plate 2 carries at its end an articulation 4 with horizontal pivot. It ends, substantially vertically, by an ear 10 which forms a first pivoting articulation part attached to the helmet. This ear 10 is pierced with a hole 11 for a horizontal pivot axis 12 having a flattened circular head 13 extended by a hollow rod 14. The pivot axis 12 is threaded into the hole 11 of the ear 10 by the interior. Its flattened circular head 13 is pressed against the rear wall of the ear 10 while its rod 14 protrudes horizontally from the front wall of the ear 10. The flattened circular head 13 of the pivot axis 12 is pierced at its periphery with holes 15 allowing its fixing by screw to the tab 3 of the plate 2. The front wall of the ear 10 takes, around the base of the rod 14 of the pivot axis 12, the shape d 'An annular plate 16 serving as a bearing for the joint.

Sur la tige creuse 14 de l'axe de pivot il vient tout d'abord une première rondelle 17, puis la deuxième pièce pivotante 18 de l'articulation qui est solidaire de la visière 5, une deuxième rondelle 19 et enfin un circlip 20 qui s'encliquette dans une rainure 21 pratiquée sur l'extérieur de l'extrémité de la tige creuse 14 de l'axe du pivot pour assurer l'assemblage des pièces de l'articulation.On the hollow rod 14 of the pivot axis there comes first a first washer 17, then the second pivoting part 18 of the articulation which is integral with the visor 5, a second washer 19 and finally a circlip 20 which engages in a groove 21 formed on the outside of the end of the hollow rod 14 of the pivot axis to ensure the assembly of the parts of the joint.

Les première et deuxième rondelles 17, 19 servent de cales d'épaisseur. Elles sont pelables. En ajustant leurs épaisseurs individuelles tout en leur conservant une épaisseur globale constante, on peut faire varier la position latérale de la deuxième pièce pivotante 18 de l'articulation par rapport à la platine 2 pour un réglage transversal fin de la position de la visière 5 par rapport au casque.The first and second washers 17, 19 serve as shims. They are peelable. By adjusting their individual thicknesses while keeping them a constant overall thickness, the lateral position of the second pivoting part 18 of the articulation can be varied relative to the plate 2 for fine transverse adjustment of the position of the visor 5 by compared to the helmet.

La deuxième pièce pivotante 18 de l'articulation est enfilée sur la tige 14 de l'axe de pivot 12 par un orifice 25 bordé, du côté tourné vers l'oreille 10 de la platine, d'un plateau annulaire 26 servant de portée à l'articulation. Sensiblement verticale, elle est attachée à la visière par l'intermédiaire d'une patte intercalaire 27 qui lui est fixée par un système de brides plates 28, 29 boulonnées autorisant un ajustement de leurs positions respectives dans le plan vertical grâce à des orifices de perçage 30, 31, 32, 33 de formes oblongues en direction horizontale pour la bride plate 28 de la deuxième pièce pivotante 18 et en direction verticale pour la bride plate 29 de la patte intercalaire 27. Cet ajustement dans le plan vertical des positions relatives de la deuxième pièce pivotante 18 et de la patte intercalaire 27 permet un réglage fin en hauteur et profondeur de la position de la visière par rapport au casque lorsqu'elle est rabattue.The second pivoting part 18 of the articulation is threaded on the rod 14 of the pivot axis 12 by an orifice 25 bordered, on the side facing the ear 10 of the plate, with an annular plate 26 serving as a bearing for the joint. Significantly vertical, it is attached to the visor by means of an intermediate tab 27 which is fixed to it by a system of flat flanges 28, 29 bolted allowing an adjustment of their respective positions in the vertical plane by means of drilling orifices 30, 31, 32, 33 of oblong shapes in the horizontal direction for the flat flange 28 of the second pivoting part 18 and in the vertical direction for the flat flange 29 of the intermediate tab 27. This adjustment in the vertical plane of the relative positions of the second pivoting part 18 and the intermediate tab 27 allows fine adjustment in height and depth of the position of the visor relative to the helmet when it is folded down.

La patte intercalaire 27 présente, au dos de sa bride plate 29 qui vient se fixer derrière la bride plate 28 de la deuxième pièce pivotante 18, une rainure 34 sensiblement verticale emprisonnant les écrous des boulons de fixation pour les bloquer en rotation tout en les laissant libres de coulisser pour l'ajustement des positions relatives des brides 28, 29. Elle se prolonge, du côté de la visière par une languette 35 percée de trous de rivetage 36, 37 prévus pour des rivets ancrés dans le côté de la visière.The intermediate tab 27 has, on the back of its flat flange 29 which is fixed behind the flat flange 28 of the second pivoting part 18, a substantially vertical groove 34 trapping the nuts of the fixing bolts to block them in rotation while leaving them free to slide for the adjustment of the relative positions of the flanges 28, 29. It is extended, on the side of the visor by a tongue 35 pierced with riveting holes 36, 37 provided for rivets anchored in the side of the visor.

L'articulation 4 est pourvue d'un mécanisme de blocage par encliquetage dans une position particulière correspondant à la position rabattue de la visière. Ce mécanisme de blocage est constitué d'une rainure diamétrale 40 pratiquée dans la portée du plateau annulaire 26 de la deuxième pièce pivotante 18 de manière à réaliser une empreinte femelle, et d'une clavette 41 aux dimensions de la rainure diamétrale 40 montée élastiquement en relief sur la portée du plateau annulaire 16 de l'oreille 10 de la platine 2 de manière à réaliser une empreinte mâle.The articulation 4 is provided with a latching locking mechanism in a particular position corresponding to the folded position of the visor. This locking mechanism consists of a diametrical groove 40 formed in the range of the annular plate 26 of the second pivoting part 18 so as to produce a female imprint, and of a key 41 to the dimensions of the diametrical groove 40 mounted elastically in relief on the bearing surface of the annular plate 16 of the ear 10 of the plate 2 so as to produce a male imprint.

La clavette 41 est placée dans un logement rectangulaire à sa taille creusé au centre de la première rondelle 17 intercalée entre les deux pièces pivotantes 10, 18 de l'articulation. Solidaire en rotation de l'axe de pivot 12 et donc de la platine 2, elle se débat en profondeur le long de l'axe de pivot 12 au travers d'un trou diamétral 42 oblong traversant les parois de la tige creuse 14 de l'axe de pivot 12. Elle est fixée transversalement à l'extrémité d'une tirette 43 qui pénètre dans la tige 14 de l'axe de pivot au travers de la deuxième pièce pivotante 18 de l'articulation et qui prolonge la base d'un bouton poussoir 44 coiffant l'extrémité de la tige creuse de l'axe de pivot 12. Un ressort de compression 45 bobiné autour de la tirette 43 prend appui entre la base du bouton poussoir 44 et le flanc de la deuxième pièce pivotante 18 tourné vers l'extérieur de l'articulation et tend à extraire la tirette 43 de la tige creuse 14 de l'axe de pivot et à rapprocher la clavette 41 de la partie rainurée de la deuxième pièce pivotante 18 de l'articulation.The key 41 is placed in a rectangular housing at its size hollowed out in the center of the first washer 17 interposed between the two pivoting parts 10, 18 of the joint. In rotation with the pivot axis 12 and therefore with the plate 2, it struggles in depth along the pivot axis 12 through a oblong diametral hole 42 passing through the walls of the hollow rod 14 of the pivot axis 12. It is fixed transversely to the end of a pull rod 43 which enters the rod 14 of the pivot axis through the second pivoting part 18 of the joint and which extends the base of a push button 44 covering the end of the hollow rod of the pivot axis 12. A compression spring 45 wound around the pull tab 43 is supported between the base of the push button 44 and the side of the second pivoting part 18 turned towards the outside of the joint and tends to extract the pull rod 43 from the hollow rod 14 from the pivot axis and to bring the key 41 closer to the grooved part of the second pivoting part 18 of the joint.

Au cours d'une manoeuvre de la visière, la clavette 41 qui est solidaire en rotation du casque glisse sur la portée du plateau annulaire 26 de la deuxième pièce pivotante 18 solidaire en rotation de la visière jusqu'à ce qu'elle se retrouve alignée avec la rainure diamétrale 40 ce qui se produit lorsque la visière parvient dans la position rabattue convenant au viseur de casque. Elle s'encliquette alors dans la rainure 40 bloquant l'articulation.During a maneuver of the visor, the key 41 which is integral in rotation with the helmet slides on the surface of the annular plate 26 of the second pivoting part 18 integral in rotation with the visor until it finds itself aligned with the diametrical groove 40 which occurs when the visor reaches the folded position suitable for the helmet visor. It then snaps into the groove 40 blocking the joint.

Pour relever la visière à partir de sa position rabattue, il faut, avant de basculer la visière, appuyer sur le bouton poussoir 44 pour extraire la clavette 41 de la rainure 40 et débloquer l'articulation.To raise the visor from its folded position, before tilting the visor, press the push button 44 to extract the key 41 from the groove 40 and unlock the joint.

La deuxième pièce pivotante 18 et la patte intercalaire 27 qui la fixe à la visière sont capotées par une manette 46 en forme de coquille traversée par le bouton poussoir 44. Cette manette 46 est vissée sur des pattes 47, 48, 49 que présente la deuxième pièce pivotante 18 à la périphérie de son orifice 25 traversé par l'axe de pivot 12. Elle possède sur sa surface extérieure deux cannelures 50, 51 sensiblement horizontales allant de la visière à l'axe de pivot 12 de l'articulation et facilitant sa prise en main. Elle permet de basculer la visière sans avoir à la toucher.The second pivoting part 18 and the intermediate tab 27 which fixes it to the visor are covered by a lever 46 in the form of a shell through which the push button 44 passes. This lever 46 is screwed onto lugs 47, 48, 49 which the second has pivoting part 18 at the periphery of its orifice 25 crossed by the pivot axis 12. It has on its outer surface two substantially horizontal grooves 50, 51 running from the visor to the pivot axis 12 of the articulation and facilitating its grip. It allows you to tilt the visor without having to touch it.

Un ressort de traction 52 plus particulièrement visible sur la figure 4, accroché entre un point d'ancrage 53 sur la coque 1 du casque et la vis supérieure de fixation 54 de la manette 46 rappelle la visière en position relevée de sorte qu'il suffit au porteur du casque pour relever sa visière d'appuyer sur les boutons poussoirs 44 de déblocage des articulations.A tension spring 52 more particularly visible in FIG. 4, hooked between an anchoring point 53 on the shell 1 of the helmet and the upper fixing screw 54 of the lever 46 recalls the visor in the raised position so that it suffices the wearer of the helmet to raise his visor to press the push buttons 44 for unlocking the joints.
