Description

La présente invention a pour objet un casque, notamment pour utilisateurs d'engins motorisés. Ce casque est plus particulièrement destiné aux conducteurs des véhicules automobiles et des motocycles, ainsi qu'aux passagers de ces derniers, mais il peut aussi être utilisé avantageusement dans toute activité impliquant des risques de blessures à la tête, telles que, par exemple, aviation, sports de glace, sports d'hiver, activités professionnelles, etc. L'invention se rattache plus précisément à un casque du type « intégral •, c'est-à-dire à un casque conformé pour envelopper la totalité de la tête de l'utilisateur.The present invention relates to a helmet, in particular for users of motorized vehicles. This helmet is more particularly intended for the drivers of motor vehicles and motorcycles, as well as for the passengers of the latter, but it can also be used advantageously in any activity involving the risk of head injuries, such as, for example, aviation. , ice sports, winter sports, professional activities, etc. The invention relates more precisely to a helmet of the "integral" type, that is to say to a helmet shaped to wrap the entire head of the user.

On connaît (DE-A-3 025 770) un casque intégral démontable exécuté en deux parties indépendantes susceptibles d'être assemblées ou séparées. Lorsque le casque est démonté, il est sans doute possible de loger l'une de ses deux parties dans la seconde, en obtenant une réduction de son volume. Toutefois, dans cette situation, les deux parties du casque sont complètement séparées, de sorte qu'elles peuvent être dispersées. D'autre part, l'assemblage des deux parties indépendantes du casque est malaisé et exige une grande dextérité, en raison du fait que l'on doit les maintenir en position de jonction pendant qu'on installe leur moyen d'assemblage. En fait, un tel casque intégral est démontable, mais non repliable.We know (DE-A-3 025 770) a removable integral helmet executed in two independent parts capable of being assembled or separated. When the helmet is removed, it is probably possible to accommodate one of its two parts in the second, by obtaining a reduction in its volume. However, in this situation, the two parts of the helmet are completely separated, so that they can be dispersed. On the other hand, the assembly of the two independent parts of the helmet is difficult and requires great dexterity, due to the fact that they must be kept in the junction position while their assembly means are being installed. In fact, such a full face helmet is removable, but not foldable.

La présente invention a notamment pour objectif de remédier à ces insuffisances.The present invention aims in particular to remedy these shortcomings.

Selon l'invention, ce but est atteint au moyen d'un casque intégral comportant, d'une part, une coque ou structure rigide protectrice comprenant une coquille ou partie supérieure apte à recouvrir le sommet de la tête de l'utilisateur et une coquille ou partie inférieure destinée à protéger la mâchoire, le cou et la nuque de ce dernier, et, d'autre part, des moyens de verrouillage permettant d'accoupler rigidement ces coquilles supérieure et inférieure complémentaires dans une position déployée d'utilisation suivant laquelle elles se trouvent en contact jointif par leurs bords postérieurs, lesdites coquilles supérieure et inférieure étant dimensionnées de façon que l'une puisse se loger dans l'autre et leurs parties frontales étant conformées de manière à ménager une large ouverture entre leurs bords respectifs, ledit casque intégral étant notamment remarquable par le fait que lesdites coquilles supérieure et inférieure sont assemblées au moyen de deux articulations opposées et coaxiales et sont ainsi liées avec une aptitude de pivotement l'une par rapport à l'autre, de sorte que le casque peut être, soit replié sous un volume plus réduit, par simple pivotement réciproque desdites coquilles, de façon que l'une puisse s'escamoter à l'intérieur de l'autre, soit déployé en position d'utilisation, également par simple pivotement desdites coquilles, afin de reconstituer la forme intégrale dudit casque.According to the invention, this object is achieved by means of an integral helmet comprising, on the one hand, a protective shell or rigid structure comprising a shell or upper part capable of covering the top of the user's head and a shell or lower part intended to protect the jaw, the neck and the nape of the latter, and, on the other hand, locking means making it possible to rigidly couple these complementary upper and lower shells in a deployed position of use according to which they are in contiguous contact by their rear edges, said upper and lower shells being dimensioned so that one can be housed in the other and their front parts being shaped so as to provide a large opening between their respective edges, said helmet integral being particularly remarkable in that said upper and lower shells are assembled by means of two opposite and coaxial joints s and are thus linked with a pivoting ability with respect to one another, so that the helmet can be either folded up in a reduced volume, by simple reciprocal pivoting of said shells, so that one can retract inside the other, or deployed in the position of use, also by simply pivoting said shells, in order to reconstitute the integral shape of said helmet.

Le casque intégral selon l'invention a pour avantage de pouvoir être effectivement replié, en dehors des périodes d'utilisation, de façon à occuper un volume réduit équivalent à approximativement la moitié du volume qu'il présente lorsqu'il est déployé en position d'utilisation, ce qui facilite grandement son transport et son rangement. En outre, les différents composants du casque intégral selon l'invention demeurent toujours rattachés les uns aux autres, quel que soit l'état dudit casque (déployé ou replié), de sorte qu'ils ne peuvent être dispersés.The full-face helmet according to the invention has the advantage of being able to be effectively folded back, outside the periods of use, so as to occupy a reduced volume equivalent to approximately half the volume which it presents when it is deployed in position d 'use, which greatly facilitates its transport and storage. In addition, the various components of the integral helmet according to the invention always remain attached to one another, whatever the state of said helmet (deployed or folded), so that they cannot be dispersed.

D'autre part, ce casque intégral peut être très rapidement et très facilement replié et, surtout, replacé en position déployée d'utilisation, en raison du fait que la liaison permanente de ses deux coquilles au moyen d'articulations, permet de les replacer automatiquement en position d'accouplement, par simple pivotement, tandis qu'il est possible de prévoir un moyen de verrouillage entrant automatiquement en action lorsque les bords d'assemblage desdites coquilles viennent au contact l'un de.l'autre, en fin de course de basculement.On the other hand, this full-face helmet can be very quickly and very easily folded and, above all, replaced in the deployed position of use, due to the fact that the permanent connection of its two shells by means of joints, allows them to be replaced automatically in the coupling position, by simple pivoting, while it is possible to provide a locking means automatically coming into action when the assembly edges of said shells come into contact with each other, at the end of tilting stroke.

Les buts, caractéristiques et avantages ci-dessus et d'autres encore, ressortiront mieux de la description qui suit et des dessins annexés dans lesquels :

On se réfère auxdits dessins pour décrire un exemple avantageux, bien que nullement limitatif, d'exécution d'un casque pliant selon l'invention.Reference is made to said drawings to describe an advantageous example, although in no way limiting, of the execution of a folding helmet according to the invention.

Un tel casque comprend une coque ou structure rigide protectrice qui, selon l'invention, est constituée d'une coquille ou partie supérieure 1 et d'une coquille ou partie inférieure 2. Ces deux coquilles ou parties complémentaires sont dimensionnées de façon que l'une puisse se loger à l'intérieur de l'autre.Such a helmet comprises a protective shell or rigid structure which, according to the invention, consists of a shell or upper part 1 and a shell or lower part 2. These two shells or complementary parts are dimensioned so that one can fit inside the other.

De manière préférée, la coquille ou partie supérieure 1 présente un volume extérieur inférieur au volume de l'espace disponible à l'intérieur de la partie inférieure 2 du casque de façon à pouvoir venir se loger, par pivotement, à l'intérieur de cette dernière, comme cela est expliqué dans la suite du présent exposé. Cette disposition est avantageuse, en raison du fait que l'on considère, de manière conventionnelle et pratique que, durant les manoeuvres de pliage ou de développement, c'est la partie inférieure 2 qui reste immobile et constitue l'élément stable de l'ensemble, tandis que la coquille supérieure 1 est l'élément mobile et rotatif dudit ensemble. On précise, toutefois, qu'il est aussi possible d'adopter une disposition inverse suivant laquelle la coquille ou partie inférieure 2 présente un volume extérieur inférieur au volume de l'espace disponible à l'intérieur de la partie supérieure 1 du casque, de manière à pouvoir se loger, par basculement, à l'intérieur de celle-ci.Preferably, the shell or upper part 1 has an external volume less than the volume of the space available inside the lower part 2 of the helmet so as to be able to be housed, by pivoting, inside this last, as explained later in this talk. This arrangement is advantageous, due to the fact that it is considered, in a conventional and practical manner that, during the folding or development maneuvers, it is the lower part 2 which remains stationary and constitutes the stable element of the together, while the upper shell 1 is the movable and rotary element of said assembly. It is specified, however, that it is also possible to adopt a reverse arrangement according to which the shell or lower part 2 has an external volume less than the volume of the space available inside the upper part 1 of the helmet, so that it can be housed, by tilting, inside it.

Les coquilles ou parties supérieure 1 et inférieure 2 sont assemblées au moyen de deux articulations 4 et 5 opposées et coaxiales, lesquelles sont avantageusement disposées latéralement. De la sorte, la partie supérieure 1 (ou, éventuellement, la partie inférieure 2) peut pivoter (figures 2 et 5), soit pour s'escamoter complètement dans le logement réservé à l'intérieur de la partie inférieure 2 (ou, éventuellement, dans la partie supérieure 1), comme le montrent les figures 3 et 6, soit pour permettre son accouplement à ladite partie inférieure suivant une ligne équatoriale ou sensiblement équatoriale 3 du casque, ou, autrement dit, suivant le plan médian ou sensiblement médian de ce dernier, afin de reconstituer la forme intégrale dudit casque (figures 1 et 4).The shells or upper 1 and lower 2 parts are assembled by means of two opposite and coaxial joints 4 and 5, which are advantageously arranged laterally. In this way, the upper part 1 (or, optionally, the lower part 2) can pivot (Figures 2 and 5), either to retract completely into the housing reserved inside the lower part 2 (or, possibly , in the upper part 1), as shown in Figures 3 and 6, either to allow its coupling to said lower part along an equatorial or substantially equatorial line 3 of the helmet, or, in other words, along the median or substantially median plane of the latter, in order to reconstruct the integral shape of said helmet (Figures 1 and 4).

Le casque selon l'invention comprend encore des moyens de verrouillage permettant d'accoupler rigidement ses parties supérieure 1 et inférieure 2 dans la position développée d'utilisation dudit casque reconstituant la forme intégrale de ce dernier.The helmet according to the invention also comprises locking means making it possible to rigidly couple its upper 1 and lower 2 parts in the developed position of use of said helmet, reconstituting the integral shape of the latter.

Ces moyens de verrouillage peuvent être variés et deux exemples de tels moyens appropriés sont illustrés aux figures 7, 8 et 12. Suivant l'exemple de la figure 7, les moyens de verrouillage comprennent au moins un crampon coulissant 6 dont les extrémités recourbées ou crochets opposés peuvent glisser dans des rainures 7 et 8 ménagées, extérieurement dans les coquilles supérieure 1 et inférieure 2, respectivement, à proximité des bords jointifs de celles-ci et, de préférence, dans la demi-partie arrière desdites coquilles, lesdites rainures se trouvant placées parallèlement lorsque lesdites coquilles sont accouplées, dans la position développée d'utilisation. Selon ce mode d'exécution, le déverrouillage permettant le pivotement est possible grâce à une diminution de hauteur ou passage vertical ménagé dans le bourrelet délimitant l'une quelconque des rainures 7 ou 8, ledit passage permettant le dégagement de l'extrémité recourbée du crampon coulissant 6 engagée dans ladite rainure et, par conséquent, le désaccouplement des coquilles supérieure 1 et inférieure 2.These locking means can be varied and two examples of such suitable means are illustrated in FIGS. 7, 8 and 12. According to the example in FIG. 7, the locking means comprise at least one sliding clamp 6 whose curved ends or hooks opposite may slide in grooves 7 and 8 formed, externally in the upper shells 1 and lower 2, respectively, near the contiguous edges thereof and, preferably, in the rear half-part of said shells, said grooves being placed in parallel when said shells are coupled, in the developed position of use. According to this embodiment, the unlocking allowing the pivoting is possible thanks to a reduction in height or vertical passage formed in the bead delimiting any of the grooves 7 or 8, said passage allowing the release of the curved end of the crampon sliding 6 engaged in said groove and, consequently, the uncoupling of the upper 1 and lower 2 shells.

Le dispositif illustré à la figure 8 diffère du précédent, principalement par le fait que les bourrelets 9 et 10 délimitant les rainures de verrouillage dans lesquelles sont engagées les extrémités recourbées du crampon de blocage coulissant 11, sont disposées intérieurement.The device illustrated in FIG. 8 differs from the previous one, mainly by the fact that the beads 9 and 10 delimiting the locking grooves in which the curved ends of the sliding blocking crampon 11 are engaged, are arranged internally.

La figure 12 représente un autre moyen de verrouillage un peu plus complexe. Selon ce mode d'exécution, le bord de l'une des coquilles (coquille supérieure 1) est solidaire d'un doigt élastique de blocage 21 destiné à s'engager dans une petite gâche 22 ménagée dans le bord de la seconde coquille (coquille inférieure 2), ledit doigt comportant un bec venant automatiquement s'accrocher sur un épaulement que présente la paroi extérieure de ladite gâche, lorsque les bords desdites coquilles sont placés en situation jointive d'accouplement. Un poussoir 12 porté par la coquille pourvue de la gâche 22 et rappelé automatiquement par un ressort 13, permet de repousser le doigt de blocage 21 et de déverrouiller les coquilles. Ce dispositif d'accouplement élastique facilite les manoeuvres de verrouillage et de déverrouillage. Les bords d'accouplement 14 et 15 des parties supérieure 1 et inférieure 2, respectivement, du casque pliant selon l'invention, sont prévus dans la portion arrière desdites parties complémentaires. Comme le montrent les figures 7 à 12, la jonction de ces bords d'accouplement 14 et 15 n'est pas assurée au moyen de surfaces lisses, mais au moyen de reliefs et creux complémentaires. Cette disposition permet de renforcer la rigidité du casque pliant.Figure 12 shows another slightly more complex locking means. According to this embodiment, the edge of one of the shells (upper shell 1) is integral with an elastic blocking finger 21 intended to engage in a small keeper 22 formed in the edge of the second shell (shell lower 2), said finger comprising a beak coming automatically to hook onto a shoulder which has the outer wall of said keeper, when the edges of said shells are placed in contiguous mating position. A pusher 12 carried by the shell provided with the keeper 22 and automatically recalled by a spring 13, makes it possible to push back the locking finger 21 and to unlock the shells. This elastic coupling device facilitates locking and unlocking operations. The coupling edges 14 and 15 of the upper 1 and lower 2 parts, respectively, of the folding helmet according to the invention, are provided in the rear portion of said complementary parts. As shown in Figures 7 to 12, the junction of these coupling edges 14 and 15 is not ensured by means of smooth surfaces, but by means of complementary reliefs and hollows. This arrangement makes it possible to reinforce the rigidity of the folding helmet.

Selon le mode d'exécution illustré aux figures 7 et 8, l'accouplement est du type mâle-femelle, le bord d'assemblage de l'une des coquilles (coquille 1) étant pourvu d'une mortaise 16, tandis que le bord d'assemblage de la seconde coquille (coquille 2) est muni d'un tenon 17. Suivant le mode de réalisation représenté à la figure 9, l'accouplement des parties supérieure 1 et inférieure 2 est réalisé au moyen d'un assemblage à emboîtement 18.According to the embodiment illustrated in Figures 7 and 8, the coupling is of the male-female type, the assembly edge of one of the shells (shell 1) being provided with a mortise 16, while the edge of assembly of the second shell (shell 2) is provided with a lug 17. According to the embodiment shown in FIG. 9, the coupling of the upper 1 and lower 2 parts is carried out by means of a snap-on assembly 18.

Les figures 10 et 11 montrent que le tenon 17 de l'assemblage mâle-femelle peut être prévu soit sur la partie supérieure 1, soit sur la partie inférieure 2.FIGS. 10 and 11 show that the post 17 of the male-female assembly can be provided either on the upper part 1 or on the lower part 2.

On obtient un bon équilibre en prévoyant des portées distinctes le long des bords opposés 14 et 15, de façon que dans l'une d'elles l'assemblage soit conforme au mode d'exécution illustré à la figure 10 et, dans l'autre, corresponde à la réalisation représentée à la figure 11, ou bien en plaçant le tenon 17 alternativement sur la partie supérieure 1 et sur la partie inférieure 2.A good balance is obtained by providing separate spans along the opposite edges 14 and 15, so that in one of them the assembly conforms to the embodiment illustrated in Figure 10 and, in the other , corresponds to the embodiment shown in FIG. 11, or else by placing the pin 17 alternately on the upper part 1 and on the lower part 2.

Il est évident que le casque pliant selon l'invention peut avoir toute forme extérieure permettant le pivotement de l'une de ses parties complémentaires et son escamotage dans l'autre.It is obvious that the folding helmet according to the invention can have any external shape allowing the pivoting of one of its complementary parts and its retraction in the other.

D'autre part, ce casque peut être doté de ses compléments et équipements habituels tels que visière 19 et capitonnage intérieur 20. On conçoit que ledit capitonnage 20 doit avoir la forme appropriée pour autoriser les pivotements de la partie supérieure 1 (ou, suivant le cas, de la partie inférieure 2), en vue du pliage ou du développement du casque.On the other hand, this helmet can be equipped with its Complements and usual equipment such as visor 19 and interior upholstery 20. It is understood that said upholstery 20 must have the appropriate shape to allow the pivoting of the upper part 1 (or, as the case may be, of the lower part 2), in view of the folding or developing the helmet.

Selon le mode d'exécution illustré, la visière 19 est fixée sur la partie supérieure 1, au moyen d'articulations latérales 23, opposées et coaxiales, et ces articulations sont disposées à distance des articulations 4 et 5 des coquilles supérieure 1 et inférieure 2. En outre, les articulations 23 de la visière pivotante 19 sont disposées au-dessus et en arrière des articulations 4 et 5, lorsque les parties supérieure 1 et inférieure 2 sont accouplées en position développée. De la sorte, lorsque la partie supérieure 1 est escamotée à l'intérieur de la partie inférieure 2, par pivotement vers l'avant, la visière 19 vient entourer la portion antérieure de cette dernière, comme le montrent les figures 3 et 6, ses articulations 23 se trouvant placées, dans cette position, en avant des articulations 4, 5 desdites parties supérieure et inférieure.According to the illustrated embodiment, the visor 19 is fixed to the upper part 1, by means of lateral articulations 23, opposite and coaxial, and these articulations are arranged at a distance from the articulations 4 and 5 from the upper 1 and lower 2 shells. In addition, the joints 23 of the pivoting visor 19 are arranged above and behind the joints 4 and 5, when the upper 1 and lower 2 parts are coupled in the developed position. In this way, when the upper part 1 is retracted inside the lower part 2, by pivoting forwards, the visor 19 comes to surround the anterior portion of the latter, as shown in FIGS. 3 and 6, its joints 23 being placed, in this position, in front of the joints 4, 5 of said upper and lower parts.

On observe que, dans la position de pliage (figures 3 et 6), le bord d'accouplement 14 de la partie supérieure 1 dont la dimension est égale à celle du bord d'accouplement 15 de la partie inférieure 2, se trouve placé au niveau de la découpe ménagée, pour la visibilité, dans la portion antérieure de ladite partie inférieure, de sorte que le pivotement de ladite partie supérieure n'est aucunement contrarié par cette égalité de dimensions.It is observed that, in the folding position (FIGS. 3 and 6), the coupling edge 14 of the upper part 1, the dimension of which is equal to that of the coupling edge 15 of the lower part 2, is placed at the level of the cutout, for visibility, in the front portion of said lower part, so that the pivoting of said upper part is in no way hampered by this equality of dimensions.
