Abstract
Description
Dispositif dc fixation et de manoeuvre d'écran transparent pour les casques de motocyclistes et similaires. Transparent screen fixing and operating device for motorcycle helmets and the like.
Il est destiné à permettre son verrouillage en position fermée, son immobilisation dans une position d'ouverture partielle ou totale et son interchangeabilité par démontage simplifié. It is intended to allow its locking in the closed position, its immobilization in a partial or total open position and its interchangeability by simplified disassembly.
Les écrans actuels ne~ permettent généralement pas leur manoeuvre d'ouverture ou de fermeture à l'aide d'une seule main par simple action sur l'écran lui-même. De plus, l'inter- changeabilité de cet écran doit pour en modifier la transparence, soit pour le nettoyer, soit enfin pour le changer demande une série d'opérations avec l'aide d'outils. Current screens do not generally allow their opening or closing maneuver using a single hand by simple action on the screen itself. In addition, the interchangeability of this screen must, to modify its transparency, either to clean it, or finally to change it requires a series of operations with the help of tools.
Le dispositif suivant l'invention supprime ces inconvénients et facilite la manoeuvre instantanée pour le positionnement de l'écran sur la calotte du casque avec sa stabilisation en toute position, mais permet surtout d'assurer son amovibilité sans outillage spécial. The device according to the invention eliminates these drawbacks and facilitates instantaneous maneuvering for positioning the screen on the cap of the helmet with its stabilization in any position, but above all makes it possible to ensure its removability without special tools.
Il est constitué par la combinaison de deux mécanismes symétriques placés de chaque côté du casque consistant en un boîtier plat dans lequel se déplace l'extrémité de l'écran à profil fonctionnel et qui est rendu solidaire de lCa coque par deux glissières. It consists of the combination of two symmetrical mechanisms placed on each side of the helmet consisting of a flat box in which the end of the screen with a functional profile moves and which is made integral with the shell by two slides.

La figure 5 est une vue en coupe suivant les lignes
CD et EF, de la figure 3.Figure 5 is a sectional view along the lines
CD and EF, of figure 3.
L'écran 1, figure 1, est en position fermée et en position semi-ouverte 1'. The screen 1, FIG. 1, is in the closed position and in the semi-open position 1 ′.
Le dispositif de préhension 2 est placé à la partie inférieure. L'écran 1 dans sa position fermée est encastré dans la feuillure 3 pratiquée dans la calotte. The gripping device 2 is placed at the bottom. The screen 1 in its closed position is embedded in the rebate 3 formed in the cap.
Le dispositif de préhension de l'écran, figure 2, est constitué par la trappe 2 reliée à la calotte 5 par un ressort à lame 4 qui fait fonction de charnière et de ressort de rappel ainsi que de butée dans le sens de mouvement vers l'extérieur. The screen gripping device, Figure 2, is constituted by the hatch 2 connected to the cap 5 by a leaf spring 4 which acts as a hinge and return spring as well as a stop in the direction of movement towards the 'outside.
En faisant pression sur la trappe 2 suivant le sens de la flèche P, on efface partiellement la feuillure. By pressing the hatch 2 in the direction of the arrow P, the rebate is partially erased.
La trappe prenant la position tracée en traits pointillés permet au doigt de relever l'écran 1, suivant la flèche
R.The hatch taking the position traced in dotted lines allows the finger to raise the screen 1, according to the arrow
R.
Le dispositif de fixation de l'écran sur la calotte est formé par une boîtier composé par une embase 6 et par un couvercle 7 assemblés par un rivetage 8 (Fig 3, 4, 5) après intro (diction de l'écran 1. Chaque boîtier , gauche et droit est fixé sur la calotte par engagement dans les glissières 9 pratiquées dans la pièce 10, elle-même fixée sur la coque 5. The device for fixing the screen to the cap is formed by a housing composed by a base 6 and by a cover 7 assembled by a riveting 8 (Fig 3, 4, 5) after intro (diction of the screen 1. Each housing, left and right is fixed on the cap by engagement in the slides 9 made in the part 10, itself fixed on the shell 5.
Cette pièce 10 comporte le clip 11 qui empêche le boîtier de s'échapper des glissières 9. This part 10 comprises the clip 11 which prevents the housing from escaping from the slides 9.
L'extrémité de 1 'écran introduit dans les boîtiers comporte une lumière oblongue 12 qui se déplace en appui sur le bossage 13 et deux bossages 14, 15 qui s'appuient sur les rampes 16 et 17. The end of the screen introduced into the housings comprises an oblong slot 12 which moves in abutment on the boss 13 and two bosses 14, 15 which bear on the ramps 16 and 17.
Cet ensemble de guidage impose à l'écran sa trajectoire au cours de son déplacement de la position fermée à la position ouverte. This guide assembly imposes on the screen its trajectory during its displacement from the closed position to the open position.
Le tenon 18 légèrement en forme de queue d' aronde s'introduit dans le logement 19 également en queue d'aronde, grâce à sa possibilité de déformation élastique facilité par la fente 20. The tenon 18 slightly in the shape of a dovetail is introduced into the housing 19 also in dovetail, thanks to its possibility of elastic deformation facilitated by the slot 20.
Un certain effort doit être exercé sur l'écran afin de l'engager ou de le dégager de sa position fermée qui correspond au tenon 18 en place dans le logement 19. A certain effort must be exerted on the screen in order to engage or disengage it from its closed position which corresponds to the lug 18 in place in the housing 19.
C'est le bossage 21 qui sous l'effet de la précontrainte subie par l'embase 6 lors de son rivetage sur le couvercle 7 exerce une pression sur l'écran 1 et provoque une fermeté dans ses déplacements, lui permettant de conserver des positions intermédiaires malgré la pression exercée par l'air, due à la vitesse. It is the boss 21 which under the effect of the prestressing undergone by the base 6 when it is riveted on the cover 7 exerts pressure on the screen 1 and causes firmness in its movements, allowing it to maintain positions intermediate despite the pressure exerted by the air, due to the speed.
L'écran de rechange est fourni avec les boîtiers montés à ses extrémités, comprenant l'embrase 6 et le couvercle 7. The replacement screen is supplied with the boxes mounted at its ends, comprising the base 6 and the cover 7.
Pour changer d'écran, il suffit d'appuyer sur les clips 11 en tirant vers l'avant. To change the screen, simply press the clips 11 while pulling forward.
Pour la mise en place de l'écran 1, il faut engager les boîtiers dans leurs glissières 9 respectives et pousser vers l'arrière jusqu'au franchissement des clips 11. For the installation of the screen 1, it is necessary to engage the boxes in their respective slides 9 and push backwards until the clips 11 are crossed.
Le moyen principal avec la combinaison des organes consiste en un boîtier plat dans lequel se déplace l'extrémité de l'écran 1 découpé suivant un profil spécifique, comportant une lumière oblongue traversée par un bossage cylindrique solidaire du boîtier et servant de guide pendant le déplacement. The main means with the combination of the members consists of a flat case in which the end of the screen 1 cut out following a specific profile moves, comprising an oblong lumen traversed by a cylindrical boss fixed to the case and serving as a guide during the movement .
Le profil de l'écran comporte également des bossages s'appuyant chacun sur une rampe permettant à l'écran de se déplacer suivant une trajectoire bien définie qui le maintient le plus près possible de la calotte dans les positions intermédiaires et lui permet au début de l'ouverture de se dégager de la feuillure pratiquée dans la calotte, autour de la lunette et dans laquelle il est encastré dans la position fermée. The profile of the screen also includes bosses each leaning on a ramp allowing the screen to move along a well-defined trajectory which keeps it as close as possible to the cap in the intermediate positions and allows it at the start of the opening to emerge from the rabbet formed in the cap, around the bezel and in which it is embedded in the closed position.
Cet ensemble est compléte par- un dispositif de préhension facilitant la manoeuvre avec un seul doigt pour faire pression de bas en haut sur le bord inférieur de écran pour l'ouvrir rapidement et sans difficulté. This set is completed by a gripping device facilitating the operation with a single finger to apply pressure from bottom to top on the lower edge of the screen to open it quickly and without difficulty.
A cet effet, on peut pratiquer au centre de la partie de la calotte appelée "protection maxiliaire" et sous le bord inférieur de 1 'écran, une petite ouverture obstruée par une- petite trappe mobile, qui en s'enfonçant sous la pression du doigt, dégage partiellement le bord inférieur de l'écran. For this purpose, one can practice in the center of the part of the cap called "maxillary protection" and under the lower edge of one screen, a small opening obstructed by a small mobile hatch, which sinking under the pressure of the finger, partially clears the bottom edge of the screen.
Toutefois les formes, dimensions et dispositions des différents éléments, pourront varier dans la limite des équiva lents, comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela, la conception générale de l'invention qui vient d'être décrite. However, the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents, like the materials used for their manufacture, without changing the general conception of the invention which has just been described.
