The present invention relates to a sports helmet of the enveloping type, capable of being provided according to the requirements of the user, with a visor or a front element.

Comme on le sait, les usagers de motocyclettes, soit comme simple moyen de transport, soit pour la compétition, employent habituellement des casques pour la protection de la tête en cas de chute.As we know, motorcycle users, either as a means of transport or for competition, usually use helmets for head protection in the event of a fall.

On sait également que, selon les conditions climatiques, I'usager peut employer un casque fermé avec visière, ou un casque ouvert sur l'avant du visage et pourvu d'un simple élément frontal.It is also known that, depending on the climatic conditions, the user can use a closed helmet with visor, or a helmet open on the front of the face and provided with a simple frontal element.

Cette exigence demande demande que l'usager soit pourvu de deux casques différents.This requirement requires that the user be provided with two different helmets.

Le but de la présente invention est d'éliminer cet inconvénient, en réalisant un casque de sport (ou casque intégral), de type enveloppant, sur lequel on peut appliquer, selon les exigences de l'usager, soit une visière soit un élément frontal.The object of the present invention is to eliminate this drawback, by making a sports helmet (or full-face helmet), of the enveloping type, to which, depending on the user's requirements, either a visor or a front element can be applied. .

Pour atteindre le but mentionné ci-dessus, la présente invention réalise un casque de sport de type enveloppant, appelé aussi casque intégral, sur lequel ladite visière et ledit élément frontal peuvent être appliqués de manière facile par de simples opérations manuelles.To achieve the above-mentioned object, the present invention provides an enveloping type sports helmet, also called an integral helmet, to which said visor and said front element can be applied easily by simple manual operations.

Un autre but de la présente invention, est de réaliser un casque de sport de type enveloppant qui, une fois muni de la visière ou de l'élément frontal soit très sûr. Another object of the present invention is to provide a sports helmet of the enveloping type which, once fitted with the visor or the front element, is very safe.

Les buts mentionnés ci-dessus, ainsi que d'autres qui apparaîtront dans la description suivante, sont atteints par un casque de sport de type enveloppant, caractérisé en ce qu'il est pourvu, en correspondance des extrémités de l'ouverture frontale, d'éléments façonnés correspondants, formant la partie de connexion de deux dispositifs de blocage rapide, auxquels on peut accoupler les extrémités convenablement façonnées d'une visière ou d'un élément frontal, ces dispositifs de blocage rapide comprenant en particulier un élément fixe solidaire de la calotte dudit casque et un élément apte à tourner partiellement superposé sur l'élément fixe.The objects mentioned above, as well as others which will appear in the following description, are achieved by a sports helmet of the enveloping type, characterized in that it is provided, in correspondence with the ends of the front opening, of 'corresponding shaped elements, forming the connection part of two rapid locking devices, to which the suitably shaped ends of a visor or a front element can be coupled, these rapid locking devices comprising in particular a fixed element integral with the cap of said helmet and an element capable of turning partially superimposed on the fixed element.

En référence aux figures, le casque de sport de type enveloppant ou intégral, selon la présente invention, est formé d'une calotte 1, avec mentonnière 2 ayant une forme sensiblement conventionnelle, et pourvu en correspondance des deux extrémités de son ouverture frontale 3, d'éléments cylindriques correspondants, appropriés pour loger un premier disque 4 convenablement structuré.With reference to the figures, the sports helmet of the enveloping or integral type, according to the present invention, is formed of a cap 1, with chin strap 2 having a substantially conventional shape, and provided in correspondence with the two ends of its front opening 3, corresponding cylindrical elements, suitable for housing a first disc 4 suitably structured.

Plus précisément, ce premier disque est pourvu de deux petits goujons disposés sur sa périphérie, (non représentés) dans des positions diamètralement opposées sur l'une des faces, et susceptibles d'être insérés dans des trous traversants correspondants, formés dans ledit élément cylindrique.More specifically, this first disc is provided with two small studs arranged on its periphery, (not shown) in diametrically opposite positions on one of the faces, and capable of being inserted in corresponding through holes, formed in said cylindrical element .

Ce premier disque est en outre pourvu de deux séries de trous traversants 5 et 6 ayant des dispositions opposées, I'une d'elles étant disposée à flanc, sur l'intérieur d'une fente courbée.This first disc is further provided with two series of through holes 5 and 6 having opposite arrangements, one of them being disposed on the side, on the inside of a curved slot.

Ce premier disque est en outre pourvu d'une ouverture centrale façonnée 8, dans laquelle on peut insérer une portion saillante correspondante 9, formée dans ledit élément cylindrique, et pourvue d'un trou traversant 10.This first disc is further provided with a shaped central opening 8, into which a corresponding projecting portion 9 can be inserted, formed in said cylindrical element, and provided with a through hole 10.

Le premier disque mentionné ci-dessus coopère avec un deuxième disque 11, pourvu lui-même d'un trou traversant central 12, de manière à pouvoir être relié au premier disque et à la calotte, par une vis à écrou 13.The first disc mentioned above cooperates with a second disc 11, itself provided with a central through hole 12, so that it can be connected to the first disc and to the cap, by a nut screw 13.

Ce deuxième disque est pourvu préférablement mais non nécessairement d'une portion saillante radiale 14, et est en outre pourvu, sur la face prévue pour se superposer au premier disque, de deux petits goujons arrondis 15 et 16, disposés sur le périmètre du disque et le long d'un diamètre, et apte à être insérés dans les trous correspondants desdites séries de trous 5 et 6, ainsi que d'un petit goujon 17 s'engageant dans la fente 7 dudit premier disque.This second disc is preferably but not necessarily provided with a radial protruding portion 14, and is further provided, on the face intended to be superimposed on the first disc, with two small rounded studs 15 and 16, arranged on the perimeter of the disc and along a diameter, and adapted to be inserted into the corresponding holes of said series of holes 5 and 6, as well as a small stud 17 engaging in the slot 7 of said first disc.

Sur le deuxième disque 11 on a formé en outre, deux portions saillantes 18 et 19 ayant un profil convenable disposées sur le périmétre dudit disque dans une position opposée audit petit goujon et présentant une allure qui converge sensiblement vers la partie saillante radiale 14 dudit disque.On the second disc 11, two projecting portions 18 and 19 having a suitable profile have also been formed, arranged on the perimeter of said disc in a position opposite to said small stud and having a shape which substantially converges towards the radial projecting part 14 of said disc.

Les deux extrémités longitudinales 20 de la visière 21 et de l'élément frontal 22, se terminent par deux portions saillantes divergentes 23 et 24 présentant en correspondance avec les bords extérieurs, des profils respectivement 23' et 24' adaptés à s'engager dans les portions saillantes 18 et 19 mentionnées ci-dessus, à la périphérie dudit deuxième disque.The two longitudinal ends 20 of the visor 21 and of the front element 22, terminate in two divergent projecting portions 23 and 24 having, respectively in correspondence with the outer edges, profiles 23 'and 24' adapted to engage in the protruding portions 18 and 19 mentioned above, at the periphery of said second disc.

Dans la pratique, pour appliquer la visière ou l'élément frontal sur le casque, il suffit d'insérer dans les fentes définies par les deux disques superposés 4 et 11, les extémités de la visière ou de 1' élément frontal, en pressant jusqu'à l'engagement des portions saillantes desdits éléments dans les portions saillantes correspondantes 18 et 19, formées sur'les deux côtés desdites fentes.In practice, to apply the visor or the front element to the helmet, it suffices to insert into the slots defined by the two superimposed discs 4 and 11, the ends of the visor or of the front element, by pressing until 'in the engagement of the projecting portions of said elements in the corresponding projecting portions 18 and 19, formed on both sides of said slots.

Cette opération d'insertion et de poussée est favorisée par un profil de guidage convenable 25, formé le long des extrémités des parties saillantes 23 et 24.This insertion and pushing operation is favored by a suitable guide profile 25, formed along the ends of the protrusions 23 and 24.

Le dégagement de la visière, ou de l'élément frontal est également obtenu d'une manière très simple, comme on l'a représenté schématiquement sur la figure 7, en approchant manuellement les portions saillantes 23 et 24, de manière à dégager les profils 23' et 24' des portions saillantes 18 et 19.The clearance of the visor, or of the front element is also obtained in a very simple manner, as shown diagrammatically in FIG. 7, by manually approaching the projecting portions 23 and 24, so as to release the profiles 23 'and 24' of the protruding portions 18 and 19.

Grâce à la description précédente et à l'observation des figures annexées, on peut remarquer la grande facilité d'emploi qui caractérise le casque de sport de type enveloppant selon la présente invention. Thanks to the previous description and to the observation of the appended figures, one can notice the great ease of use which characterizes the sports helmet of the enveloping type according to the present invention.

Naturellement, les opérations d'insertion et de dégagement rapide mentionnées ci-dessus, peuvent être réalisées au moyen de dispositifs de blocage et de déblocage d'autres types, techniquement équivalents aux dispositifs décrits ci-dessus, et susceptibles de positionner convenablement la visière, au moyen de la connexion de petits goujons 15 et 16, dans l'un ou l'autre des trous des séries de trous 5 et 6. Naturally, the above-mentioned insertion and quick release operations can be carried out by means of locking and unlocking devices of other types, technically equivalent to the devices described above, and capable of properly positioning the visor, by means of the connection of small studs 15 and 16, in one or the other of the holes in the series of holes 5 and 6.
