Description

CASQUE PERFECTIONNE COMPORTANT UNE SOUS COQUE SUR LAQUELLE EST FIXEE LA COQUE EXTERNE IMPROVED HELMET HAVING AN UNDERCOAT ON WHICH THE EXTERNAL SHELL IS ATTACHED
La présente invention concerne un casque de protection, et plus précisément un casque qui est constitué d'une sous coque retenant au moins la coque externe et avantageusement la jugulaire, le bandeau de tour de tête et le calotin.The present invention relates to a protective helmet, and more specifically to a helmet which is constituted by a sub-shell retaining at least the outer shell and advantageously the chinstrap, the headband and the cap.
Les casques de protection sont depuis fort longtemps d'un usage courant dans différents domaines soit à titre professionnel comme c'est le cas pour les militaires, les pilotes d'avion ou d'hélicoptère, les gendarmes ou les pompiers, soit à titre civil ou privé, comme c'est le cas pour les utilisateurs de motos, de voitures de rallye ou de course, ou les employés de chantiers.Protective helmets have been used for a very long time in various fields, either professionally, as is the case for the military, pilots of aircraft or helicopters, gendarmes or firefighters, or in a civil capacity or private, as is the case for users of motorcycles, rally cars or racing, or construction site employees.
Ces casques de l'art antérieur sont généralement formés d'une coque externe plus ou moins rigide et d'un habillage interne destiné à permettre la mise en place du casque et à favoriser le confort de l'utilisateur, et comprennent par ailleurs une jugulaire de retenue.These helmets of the prior art are generally formed of a more or less rigid outer shell and an internal lining intended to allow the introduction of the helmet and to promote the comfort of the user, and further include a chinstrap restraint.
Le but de l'invention est alors de proposer une construction de casque autre particulièrement simple, fiable, ne nécessitant pas d'outillage particulier pour son montage.The object of the invention is then to provide a particularly simple, reliable helmet construction, which does not require special tools for mounting it.
Ainsi le casque de protection de l'invention comprend une coque externe principale de plan de symétrie longitudinal, un bandeau de tour de tête ainsi qu'une jugulaire, et est caractérisé en ce que ledit casque comprend une sous coque sur laquelle est fixée la coque externe principale.Thus, the protective helmet of the invention comprises a main outer shell of longitudinal plane of symmetry, a headband and a chinstrap, and is characterized in that said helmet comprises a sub shell on which is fixed the hull main external.
Selon des caractéristique complémentaire, la sous coque se présente sous la forme d'une large bande sensiblement circulaire en matière plastique, constituée par une paroi périphérique, tandis que la coque externe principale est fixée de façon amovible à la sous coque grâce à des moyens de connexions amovibles.According to complementary features, the under-shell is in the form of a broad, substantially circular strip of plastic material constituted by a peripheral wall, while the main outer shell is removably attached to the underbody by means of removable connections.
Ajoutons que les moyens de connexions sont constitués par au moins trois points de connexions, à savoir des premiers moyens solidaires de la sous coque destinés à coopérer avec des seconds moyens solidaires de la coque externe principale.Add that the connection means are constituted by at least three connection points, namely first integral means of the sub-shell for cooperating with second means integral with the main outer shell.
Notons aussi que la coque externe principale est fixée avantageusement à la sous coque en quatre points, à savoir un point arrière , un point avant, deux points latéraux, un point latéral gauche et un point latéral droit, tandis-que le point arrière de fixation et le point avant de fixation sont réalisés par une saillie coopérant avec un creux.Note also that the main outer shell is advantageously fixed to the underbody at four points, namely a rear point, a front point, two side points, a left side point and a right side point, while the rear point of attachment and the point before fixing are made by a projection cooperating with a hollow.
Selon une autre caractéristique, la sous coque comprend une cuvette d'encastrement arrière destinée à coopérer avec une saillie arrière de dimension correspondante faisant saillie vers l'intérieur de la coque externe principale, au niveau de la portion de paroi arrière inférieure, ainsi qu'un logement d'encastrement avant destiné à coopérer avec une saillie avant de dimensions correspondantes faisant saillie vers l'intérieur de la coque externe principale, au niveau de la portion de paroi avant supérieure, au niveau de la zone frontale de la coque, tandis qu'il est prévu une languette élastique qui après engagement de ladite saillie revient à sa position initiale afin d'en assurer le verrouillage.According to another characteristic, the underbody comprises a rear recessing cup intended to cooperate with a rear projection of corresponding dimension projecting towards the inside of the main outer shell, at the level of the lower rear wall portion, as well as a front recess housing for cooperating with a corresponding corresponding front protrusion projecting inwardly of the main outer shell, at the upper front wall portion, at the front zone of the shell, while there is provided an elastic tongue which after engagement of said projection returns to its initial position to ensure locking.
La sous coque comprend par ailleurs, de chaque coté un trou de fixation, dans chacun desquels est engagé une saillie amovible correspondante de fixation respectivement dont le verrouillage est assuré par une goupille de blocage.The sub-shell furthermore comprises, on each side, a fixing hole, in each of which is engaged a respective detachable fixing projection, the locking of which is ensured by a locking pin.
Notons que chacune des saillies de fixation sont des pièces indépendantes, qui sont par exemple issues de pièces latérales d'accrochage destinées par exemple à fixer un masque respiratoire, ou une lampe d'éclairage, voir un écran facial pivotant.Note that each of the attachment projections are independent parts, which are for example from side attachment parts for example to fix a breathing mask, or a lighting lamp, see a swivel face screen.
La sous coque assure aussi la retenue de la jugulaire , et la paroi périphérique de la sous coque comprend à cet effet un ensemble de trous destiné au passage des sangles de la jugulaire, et assure aussi la retenue du le calotin qui est en fixé sur la sous coque par clipsage, pour former un sous ensemble interne.The underbody also holds the chin strap, and the peripheral wall of the underbody comprises for this purpose a set of holes for the passage of the straps of the chin strap, and also ensures the retention of the chin strap. the cap which is fixed on the under shell by clipping, to form an internal subassembly.
D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifs.Other features and advantages of the invention will become apparent from the description which follows with reference to the accompanying drawings which are given by way of non-limiting examples.
La figure 1 est une vue en perspective éclatée du casque selon l'invention.Figure 1 is an exploded perspective view of the helmet according to the invention.
La figure 2 est une vue du sous ensemble interne, sous coque /calotin.Figure 2 is a view of the internal subassembly, under shell / cap.
La figure 3 est une vue de dessous de la coqueFigure 3 is a bottom view of the hull
La figure 4 est une vue en coupe du casque selon le plan vertical de symétrie généraleFIG. 4 is a sectional view of the helmet along the vertical plane of general symmetry
Le casque de protection représenté à titre d'exemple à la figure 1 à portant la référence générale (1) est par exemple un casque de pompier, (mais pourrait être un casque d'un tout autre genre, comme par exemple un casque militaire, de cycliste, de motocycliste ou autre) qui présente un plan longitudinal de symétrie générale (P) qui comprend de façon connue en soi une coque externe principale (2) ainsi qu'une jugulaire (12) assurant le maintien du casque sur la tête de l'utilisateur. Par ailleurs le casque comprend de façon connue en soi un calotin (13) ainsi qu'un bandeau de tour de tête (14), et peut comprendre aussi un écran facial pivotant (15).The protective helmet represented by way of example in FIG. 1 with the general reference (1) is for example a fireman's helmet (but could be a helmet of a completely different kind, such as for example a military helmet, cyclist, motorcyclist or other) which has a longitudinal plane of general symmetry (P) which comprises in known manner a main outer shell (2) and a chinstrap (12) ensuring the maintenance of the helmet on the head of the user. Furthermore the helmet comprises in known manner a cap (13) and a headband (14), and may also include a pivoting face shield (15).
La coque externe principale (2) est constituée par une paroi sensiblement sphérique de plan général vertical de symétrie (P) qui est réalisée avantageusement en matériau composite du type comprenant par exemple un empilage de couches de fibres de renfort, imprégnées et liées entre elles par une matrice en résine. Les fibres peuvent être des fibres de verre, d'aramide, de Nylon, de polyéthylène ou de carbone, tandis que la matrice peut être une résine du type thermodurcissable ou thermoplastique. Bien entendu, la coque pourrait être en tout autre matériau comme, par exemple réalisée par injection d'une matière plastique, et avantageusement d'une matière plastique chargée.The main outer shell (2) consists of a substantially spherical wall of general vertical plane of symmetry (P) which is advantageously made of a composite material of the type comprising, for example, a stack of layers of reinforcing fibers, impregnated and bonded together by a resin matrix. The fibers may be glass, aramid, nylon, polyethylene or carbon fibers, while the matrix may be a thermosetting or thermoplastic resin. Of course, the hull could be in any other material such as, for example, made by injection of a plastic material, and preferably a filled plastic material.
La coque externe principale (2) comprend plusieurs portions de paroi, comme le montre la figure 1, à savoir une portion avant supérieure de paroi (3) prolongée vers l'arrière par une portion arrière supérieure de paroi (4), elle-même prolongée vers le bas par une portion arrière inférieure de paroi (5), et comprend, par ailleurs, deux portions latérales de paroi (6a, 6b).The main outer shell (2) comprises several wall portions, as shown in Figure 1, namely an upper wall front portion (3) extended rearwardly by an upper rear wall portion (4), itself extended downwards by a lower rear wall portion (5), and further comprises two sidewall portions (6a, 6b).
La portion avant supérieure (3) correspond à la zone occupée par le front de l'utilisateur et est limitée par la bordure supérieure (7) de l'ouverture faciale (8) qui, quant à elle, est limitée latéralement par deux bordures latérales (9a, 9b).The upper front portion (3) corresponds to the area occupied by the user's forehead and is limited by the upper edge (7) of the facial opening (8) which, in turn, is limited laterally by two side edges. (9a, 9b).
La portion avant supérieure de paroi (3) correspond à la zone occupée par la boîte crânienne de l'utilisateur, tandis que la portion arrière inférieure de paroi (5) correspond à la zone occupée par la nuque de l'utilisateur.The upper front wall portion (3) corresponds to the area occupied by the cranial box of the user, while the lower rear wall portion (5) corresponds to the area occupied by the neck of the user.
Ajoutons à cela que la paroi de la coque est limitée vers le bas par une bordure inférieure (10). Les portions latérales de paroi (7a, 7b) correspondent aux zones occupées par les oreilles de l'utilisateur et sont limitées vers l'avant par la bordure latérale correspondante (9) de l'ouverture faciale (8) et vers le bas par la bordure inférieure (10).Add to this that the wall of the shell is limited downward by a lower border (10). The lateral wall portions (7a, 7b) correspond to the areas occupied by the user's ears and are limited forwardly by the corresponding lateral border (9) of the facial opening (8) and downwards by the lower border (10).
Selon l'invention, le casque de protection (1) comporte des moyens de maintien de la coque principale (2) constitués par une sous coque (11).According to the invention, the protective helmet (1) comprises means for maintaining the main hull (2) constituted by an underbody (11).
Par ailleurs cette sous coque (11) assure la retenue dé la jugulaire (12) permettre l'ajustement et la fixation du casque (1) sur la tête de l'utilisateur.Moreover this under shell (11) ensures the retention of the chinstrap (12) allow adjustment and attachment of the helmet (1) on the head of the user.
La sous coque (11) se présente sous la forme d'une large bande sensiblement circulaire en matière plastique, constituée par une paroi périphérique. Selon l'invention la coque externe principale (2) est fixée de façon amovible à la sous coque (11) grâce à des moyens de connexions amovibles. Ces moyens sont constitués par au moins trois points de connexions des premiers moyens solidaires de la sous coque (11) destinés à coopérer avec des seconds moyens solidaires de la coque externe principale (2).The underbody (11) is in the form of a broad band substantially circular plastic material consisting of a peripheral wall. According to the invention, the main outer shell (2) is removably attached to the underbody (11) by means of removable connections. These means consist of at least three connection points of the first integral means of the sub-shell (11) for to cooperate with second means integral with the main outer shell (2).
Selon le mode préféré donné à titre d'exemple la coque externe principale (2) est fixée à la sous coque (11) en quatre points, à savoir un point arrière (16), un point avant (17), deux points latéraux (18a, 18), un point latéral gauche (18a) et un point latéral droit (18b).According to the preferred embodiment given by way of example, the main outer shell (2) is fixed to the underbody (11) at four points, namely a rear point (16), a front point (17), two lateral points ( 18a, 18), a left side point (18a) and a right side point (18b).
Le point arrière de fixation (16) est réalisé par une saillie coopérant avec un creux. Ainsi, la sous coque (11) comprend une cuvette d'encastrement (19) destiné à coopérer avec une saillie arrière (20) de dimension correspondante faisant saillie vers l'intérieur de la coque externe principale, au niveau de la portion de paroi arrière inférieure (5).The rear attachment point (16) is formed by a projection cooperating with a recess. Thus, the underbody (11) comprises a recess cup (19) for cooperating with a rear projection (20) of corresponding dimension projecting inwardly of the main outer shell, at the rear wall portion lower (5).
Le point avant de fixation (17) est réalisé par une saillie coopérant avec un profil en creux. Ainsi, la sous coque (11) comprend un logement d'encastrement (21) destiné à coopérer avec une saillie avant (22) de dimensions correspondantes faisant saillie vers l'intérieur de la coque externe principale, au niveau de la portion de paroi avant supérieure (3), au niveau de la zone frontale de la coque. Afin de permettre l'engagement de la saillie avant (22) dans son logement correspondant (21) de la sous coque, il est prévu une languette élastique (210) qui après engagement de ladite saillie revient à sa position initiale afin d'en assurer le verrouillage.The fixing front point (17) is formed by a projection cooperating with a recessed profile. Thus, the underbody (11) comprises a recess housing (21) intended to cooperate with a corresponding projection (22) of corresponding dimensions projecting towards the inside of the main outer shell, at the level of the front wall portion. upper (3), at the frontal area of the hull. In order to allow engagement of the front projection (22) in its corresponding housing (21) of the underbody, there is provided an elastic tongue (210) which after engagement of said projection returns to its initial position to ensure locking.
Les points latéraux de fixation (18a, 18b) sont réalisés chacun par une saillie coopérant avec un profil en creux. Ainsi, la sous coque (11) comprend de chaque coté un trou de fixation (23a, 23b), dans chacun desquels est engagé une saillie amovible correspondante de fixation respectivement (24a, 24b) dont le verrouillage est assuré par une goupille de blocage (25). Ainsi, chacune des saillies de fixation (24a, 24b) est engagée à la fois dans un trou (180a, 180b) de la paroi latérale de la coque et dans le trou de fixation (23a, 23b) de la sous coque, et son verrouillage est assuré par la goupille de blocage qui est engagée dans un trou correspondant (240) réalisé dans la saille de fixation.The lateral attachment points (18a, 18b) are each formed by a projection cooperating with a recessed profile. Thus, the underbody (11) comprises on each side a fixing hole (23a, 23b), in each of which is engaged a respective detachable fixing protrusion respectively (24a, 24b), the locking of which is ensured by a locking pin ( 25). Thus, each of the attachment projections (24a, 24b) is engaged both in a hole (180a, 180b) of the side wall of the shell and in the attachment hole (23a, 23b) of the underbody, and its locking is provided by the locking pin which is engaged in a corresponding hole (240) made in the fastener.
Les saillies de fixation (24a, 24b) sont des pièces indépendantes, qui sont par exemple issues de pièces latérales d'accrochage (30) destinées par exemple à fixer un masque respiratoire, ou une lampe d'éclairage, voir un écran facial pivotant.The fixing projections (24a, 24b) are independent parts, which are for example coming from lateral attachment parts (30) intended to for example to attach a respirator, or a lighting lamp, see a swiveling face shield.
Ajoutons que selon le mode préféré de l'invention tel qu'illustre, la sous coque est destinée aussi à retenir la jugulaire (12). A cet effet la paroi périphérique de la sous coque comprend un ensemble de trous (26a, 26b- 27a, 27b) destiné au passage des sangles de la jugulaire. Cette dernière est donc fixée à la sous coque (11) et non à la coque (2) comme cela est le cas dans les casques traditionnels.Add that according to the preferred embodiment of the invention as illustrated, the underbody is also intended to retain the jugular (12). For this purpose the peripheral wall of the underbody comprises a set of holes (26a, 26b-27a, 27b) for the passage of the straps of the jugular. The latter is therefore attached to the underbody (11) and not to the hull (2) as is the case in traditional helmets.
Notons aussi que le calotin (13) qui est lui aussi fixé sur la sous coque (11) par clipsage. C'est donc la sous coque qui retient ce calotin.Note also that the cap (13) which is also fixed on the underbody (11) by clipping. It is therefore the underbody that holds this cap.
Ajoutons, que le casque de l'invention comprend un rembourrage de confort (28), mis en place sous le calotin qui est destiné à être en contact avec la tête de l'utilisateur et lui assurer un bon confort de portage.Add, that the headset of the invention comprises a comfort padding (28), set up under the cap that is intended to be in contact with the user's head and ensure a good wearing comfort.
Par ailleurs, le casque comprend un bandeau de tour de tête (14).In addition, the helmet comprises a headband (14).
Ledit bandeau avec la jugulaire assure le maintien du casque sur la tête de l'utilisateur.Said band with the jugular ensures the maintenance of the helmet on the head of the user.
Le bandeau de tour de tête (14) qui est constitué par une bande périphérique est fixé à la sous coque (11). Le bandeau (14) est réalisé par exemple en matière plastique déformable ou similaire, de façon à pouvoir enserrer la périphérie de la tête de l'utilisateur pour assurer une bonne retenue du casque et ce avec un confort optimal. Notons que la dimension périphérique du bandeau peut être réglée pour être adaptée à la morphologie et notamment aux dimensions de la tête de l'utilisateur. A cet effet des moyens de réglage sont prévu comme par exemple ceux décrit dans la demande de brevet française 0605223.The headband band (14) which is constituted by a peripheral band is fixed to the underbody (11). The strip (14) is made for example of deformable plastic or the like, so as to grip the periphery of the head of the user to ensure good retention of the helmet and with optimum comfort. Note that the peripheral dimension of the strip can be adjusted to be adapted to the morphology and in particular to the dimensions of the head of the user. For this purpose adjustment means are provided such as those described in French patent application 0605223.
Ainsi, le montage du casque nécessite que peu de manipulation et se fait sans outillage particulier.Thus, the mounting of the helmet requires little manipulation and is done without special tools.
Le calotin (13) est dans un premier temps clipsé sur la sous coque (11). Puis la coque est mise en place sur la sous coque. Pour se faire, la cuvette arrière d'encastrement (19) de la sous coque est engagée autour de la saillie arrière (20) de la coque, puis l'avant de la sous coque est pivoté pour venir clipsé la saillie avant (22) de la coque dans le logement d'encastrement (21) de la sous coque (11) et ce par déformation de la languette de verrouillage avant (210). La coque est alors dans sa position par rapport à la sous coque, et chacune des saillies amovibles de fixation (24a, 24b) sont alors engagées à la fois dans un trou (180a, 180b) de la paroi latérale de la coque et dans le trou de fixation de la sous coque (11), et son verrouillage est assuré par la goupille de blocage qui est engagée dans un trou correspondant (240) réalisé dans la saille de fixation.The calotin (13) is first clipped on the underbody (11). Then the hull is put in place on the underbody. To do this, the rear recessing bowl (19) of the underbody is engaged around the rear projection (20) of the hull, then the front of the hull is pivoted to snap the front projection (22) of the hull into the recess housing (21) of the hull (11) and this by deforming the front locking tab (210). The shell is then in its position relative to the underbody, and each of the removable attachment projections (24a, 24b) are then engaged both in a hole (180a, 180b) of the side wall of the shell and in the fixing hole of the sub-shell (11), and its locking is ensured by the locking pin which is engaged in a corresponding hole (240) made in the fastener.
La jugulaire (11) est avantageusement de type trois points ou quatre points et est constituée de façon connue en soi par un ensemble de sangles souples avec mentonnière.The chinstrap (11) is advantageously three-point or four-point type and is constituted in a manner known per se by a set of flexible straps with chin strap.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons. Of course, the invention is not limited to the embodiments described and represented by way of examples, but it also includes all the technical equivalents as well as their combinations.
