Abstract
Description
L'invention concerne un dispositif de guidage vertical d'une visière de protection. utilisable avec ou sans le port de lunettes correctives et escamotable à l'intérieur d'un casque de sécurité. The invention relates to a device for vertically guiding a protective visor. can be used with or without the wearing of corrective glasses and retractable inside a safety helmet.
Le guidage de ce type de visière, par jeux de biellettes formant des parallélogrammes déformables articulés, disposés à droite et à gauche de la visière de protection, sont bien connus. Mais l'utilisation de ce type de guidage, qui n'a qu'un seul degré de liberté, impose un écartement suffisant entre la visière de protection et les lunettes correctives pour éviter tout accrochage lors de la manoeuvre de mise en service de la visière ou vise-versa. n en résulte de ce fait. en position service, un manque sérieux de protection au bord inférieur de la visière. The guidance of this type of visor, by sets of rods forming articulated deformable parallelograms, arranged to the right and to the left of the protective visor, are well known. However, the use of this type of guide, which has only one degree of freedom, imposes a sufficient distance between the protective visor and the corrective glasses to avoid any catching during the operation of putting the visor into service. or vice versa. n results from this fact. in the service position, a serious lack of protection at the lower edge of the visor.
L'invention à donc essentiellement pour but de remédier à cette lacune et de proposer un dispositif à mouvement combiné qui permet, d'avoir en position escamotée à l'intérieur du casque (position haute) la visière suffisamment écartée des lunettes correctives. pour manoeuvrer librement. sans accrochage pendant la montée ou la descente de la visière et d'avoir en position service (position basse] la visière devant les yeux avec le bord inférieur de la visière appliqué sur le visage. The invention therefore essentially aims to remedy this shortcoming and to provide a combined movement device which allows, in the retracted position inside the helmet (high position) the visor sufficiently spaced from the corrective glasses. to maneuver freely. without catching during raising or lowering of the visor and having in the service position (low position] the visor in front of the eyes with the lower edge of the visor applied to the face.
La description qui va suivre en regard des dessins annexés à titre d'exemple non limitatif permettra de comprendre comment l'invention peut étre mise en pratique. The description which follows with reference to the accompanying drawings by way of nonlimiting example will make it possible to understand how the invention can be put into practice.
Dans les descriptions et les dessins qui suivent on ne considère souvent qu'un seul des côtés de la visière, en l'occurence le gauche, le côté droit étant symétrique. Sur tout les dessins, seule la partie AV du casque qui reçoit la visière est représentée. In the descriptions and the drawings which follow, we often only consider one of the sides of the visor, in this case the left, the right side being symmetrical. In all the drawings, only the front part of the helmet which receives the visor is shown.
La figure 1 - représente une vue de côté d'un dispositif connu. Figure 1 - shows a side view of a known device.
La figure 2 - represente une vue de côté d'un dispositif selon l'invention. Figure 2 - shows a side view of a device according to the invention.
La figure 3 - représente une vue de côté d'une variante du dispositif. Figure 3 - shows a side view of a variant of the device.
La figure 4 - represente une coupe suivant un axe I I. Figure 4 - represents a section along an axis I I.
La figure 1 montre une visière de protection(l) logée a l'intérieur d'un casque(2). par exemple de chantier, en position haute(H). Pour passer de la position haute(H) à la position basse(B) la visière est guidée, à droite comme à gauche. par des jeux de biellettes(3-4) formant entre elles des parallélogrammes déformables, articulés à l'intérieur du casque(2) sur les tourillons(5-6) et sur les faces laterales(l8) de la visière(1) sur les tourillons(7-8). On volt sur la figure 1 en position(B) au bord inferleur de la visière(1a) l'espace(E) laissé entre la visière de protection et le visage de l'utilisateur.Cet espace est nécessaire pour éviter que la visière(1) n'accroche les lunettes correctives(10) lors du mouvement de descente ou de montée. Figure 1 shows a protective visor (l) housed inside a helmet (2). for example on site, in the high position (H). To pass from the high position (H) to the low position (B) the visor is guided, on the right as on the left. by sets of links (3-4) forming between them deformable parallelograms, articulated inside the helmet (2) on the pins (5-6) and on the lateral faces (18) of the visor (1) on the pins (7-8). We are flying in Figure 1 in position (B) at the lower edge of the visor (1a) the space (E) left between the protective visor and the face of the user. This space is necessary to prevent the visor ( 1) does not hang the corrective glasses (10) during the downward or upward movement.
11 laisse de ce fait un passage important aux projections dirigées suivant les nèches(P-Pa) et donc un manque sérieux d'efficacité dans la protection. It therefore leaves an important passage to the projections directed along the niches (P-Pa) and therefore a serious lack of effectiveness in protection.
La figure 2 montre un dispositif, selon l'invention qui est compose de parallélogrammes déformables constitués par des blellettes hautes(3) et basses(4) articulées sur des tourillons(5-6-7-81. La particularité de ces parallélogrammes est la biellette basse(4) qui est extensible suivant la flèche(X). Cet allongement peut etre obtenu soit par un trou oblong(43) figure ici sur une des extrémités de la biellette(4) figure 2. Soit par une biellette télescopique figure 2a - soit par une biellette proprement élastique figure 2b moulée dans un matériau plastique approprié.Cette biellette extensible(4) coopère avec un ressort(9) qui tend à ramener l'articulation(8) de la visière(l) vers le tourillon(6) du casque(2) ce qui a pour effet de faire pivoter la visière d'un certain angle(Y) proportionnel à la course (Xa). Dans cette disposition il faut. pour éviter d'accrocher les lunettes correctives (10) quand on met la visière(l) en service, écarter d'abord la visière en l'emmenant en position (Ha) et la maintenir ainsi pendant le mouvement de descente. Arrivé en position(B) le ressort(9). sous tension, amène le bord inferieur(1a) de la visière au contact du visage en faisant pivoter la visière suivant la fleche(Z). L'espace(E) est réduit à zéro d'où une efficacité de protection nettement accrue.Pendant les manoeuvres de remontée de la visière, les mouvements sont inversés. FIG. 2 shows a device according to the invention which is made up of deformable parallelograms constituted by high (3) and low (4) rods articulated on trunnions (5-6-7-81. The particularity of these parallelograms is the lower link (4) which is extendable along arrow (X). This extension can be obtained either by an oblong hole (43) shown here on one of the ends of the link (4) figure 2. Or by a telescopic link figure 2a - either by a properly elastic link Figure 2b molded in a suitable plastic material.This extendable link (4) cooperates with a spring (9) which tends to bring the joint (8) of the visor (l) to the pin (6 ) of the helmet (2) which has the effect of rotating the visor by a certain angle (Y) proportional to the travel (Xa). In this arrangement it is necessary to avoid hanging the corrective glasses (10) when we put the visor (l) in service, first move the visor aside leading to position (Ha) and keep it there during the downward movement. Arrived in position (B) the spring (9). under tension, brings the lower edge (1a) of the visor into contact with the face by rotating the visor according to the arrow (Z). The space (E) is reduced to zero, resulting in a significantly increased protection efficiency. During the visor raising operations, the movements are reversed.
Dans la forme de realisation suivant la figure3, le guidage est assuré seulement par deux biellettes(3) situées l'une à droite l'autre à gauche. Cette disposition laisse à la visière(1) un degré supplémentaire de liberté puisque la visière est libre de pivoter suivant les deux sens de rotation autour du tourillon(7). La liberté de pivotement de la visière(1) est assujettie à un ressort de traction(1 1) accroché à une de ses extrémites sur le casque(2) au point d'ancrage(13) et à l'autre extrémité sur la visière(1) au point d'ancrage(l2).Le ressort(11) est placé de telle sorte qu'il maintien, pendant pratiquement tout le mouvement de montée ou de descente, la visfère(l) écartée pour éviter l'accrochage des lunettes correctives(10). En effet. sous l'action du ressort(1 1). légèrement sous tension. les points(7-12-13) restent toujours en ligne. En fin de course basse, le bord inférieur(1a) pivote suivant la flèche(FZ gardant de ce fait le bas de la visière au contact du visage quelqu'en soit la morphologie. L'utilisateur se trouve ainsi totalement protégé des projections. In the embodiment according to Figure 3, the guidance is provided only by two rods (3) located one to the right the other to the left. This arrangement leaves the visor (1) with an additional degree of freedom since the visor is free to pivot in the two directions of rotation around the pin (7). The freedom of pivoting of the visor (1) is subject to a tension spring (1 1) attached to one of its ends on the helmet (2) at the anchoring point (13) and at the other end on the visor (1) at the anchoring point (l2). The spring (11) is placed so that it keeps the screw (l) apart for practically the entire up or down movement to avoid catching the corrective glasses (10). Indeed. under the action of the spring (1 1). slightly energized. the points (7-12-13) always remain online. At the end of the lower stroke, the lower edge (1a) pivots according to the arrow (FZ thereby keeping the bottom of the visor in contact with the face whatever the morphology. The user is thus completely protected from projections.
La figure 4 montre selon la figure 3. en vue du dessus. les mecanismes du dispositif situés sur le côte gauche de la visière. les mecanismes situés du côté droit sont symétriques. Figure 4 shows according to Figure 3. seen from above. the mechanisms of the device located on the left side of the visor. the mechanisms located on the right side are symmetrical.
Comme il y va de soi et comme il résulte d'ailleurs déjà de ce qui précède, l'invention ne se limite nullement à ceux de ces modes d'application et de réalisation qui ont éte plus spécialement envisagés, elle en embrasse, au contraire, toutes les variantes. As goes without saying and as it moreover already results from the foregoing, the invention is in no way limited to those of these modes of application and embodiments which have been more especially envisaged, it embraces them, on the contrary , all variants.
