Description

La présente invention concerne le domaine technique de la progression sécurisée d'un utilisateur. Elle est plus particulièrement, mais non exclusivement, relative à une telle progression sécurisée à l'intérieur d'un tunnel.The present invention relates to the technical field of the secure progression of a user. She is more particularly, but not exclusively, relating to a such secure progression inside a tunnel.

Dans un passé récent, on a eu à déplorer des incendies particulièrement dramatiques dans des tunnels, impliquant l'intervention des pompiers. Dans de telles conditions, ces derniers doivent alors s'orienter à l'intérieur du tunnel, ce qui est malaisé notamment en raison de l'épaisse fumée générée par l'incendie.In the recent past, there have been fires particularly dramatic in tunnels, involving intervention of firefighters. Under such conditions, these the latter must then orient themselves inside the tunnel, which is difficult especially due to the thick smoke generated by the fire.

A cet égard, on a proposé de réaliser un rail, s'étendant le long de la paroi du tunnel, sur lequel différents chariots sont montés de façon mobile. De la sorte, chaque pompier s'accroche à un chariot correspondant, par exemple par l'intermédiaire d'un mousqueton, afin de pouvoir progresser dans le tunnel de manière sécurisée.In this regard, it has been proposed to produce a rail, extending along the wall of the tunnel, on which different carriages are movably mounted. Of the so each firefighter hangs on a cart correspondent, for example through a carabiner, in order to progress through the tunnel secure way.

Cette solution connue implique cependant certains inconvénients.This known solution, however, involves certain disadvantages.

Ainsi, le rail précité est constitué d'une succession d'éléments de longueur donnée, qui sont disposés les uns derrière les autres. De ce fait, étant donné que ces éléments métalliques sont sujet de façon sensible au phénomène de dilatation, le rail a tendance à se distordre fortement sous l'effet de la chaleur, ce qui peut empêcher la progression du chariot.Thus, the aforementioned rail consists of a succession elements of given length, which are arranged one behind the others. Therefore, since these metallic elements are subject to a sensitive expansion phenomenon, the rail tends to distort strongly under the effect of heat, which can prevent progress of the carriage.

De plus, chaque pompier subit l'inertie du chariot, lors de sa progression, ce qui rend cette dernière relativement lente. Par ailleurs, l'emploi d'un tel chariot se révèle particulièrement peu commode. A cet égard, il convient de noter que, de façon générale, ce chariot ne peut être placé sur le rail qu'à une extrémité de celui-ci. In addition, each firefighter undergoes the inertia of the truck, as it progresses, making it relatively slow. Furthermore, the use of such a cart is particularly inconvenient. In this regard, he Please note that, in general, this cart does not can be placed on the rail only at one end of it.

Enfin, cette solution implique de disposer d'un nombre élevé de chariots, si de nombreux pompiers doivent intervenir au coeur du tunnel.Finally, this solution involves having a number high carts, if many firefighters have to intervene at the heart of the tunnel.

En effet, chaque chariot peut assurer seulement la progression d'un unique pompier. De la sorte, lorsque tous les chariots sont déjà en service, d'éventuels pompiers supplémentaires ne peuvent plus intervenir, sauf à se déplacer dans des conditions incompatibles avec leur propre sécurité.Indeed, each trolley can only ensure the progression of a single firefighter. So when all the trolleys are already in service, possible firefighters can no longer intervene, except when move in conditions incompatible with their own security.

Ceci étant précisé, l'invention se propose de remédier aux différents inconvénients de l'art intérieur évoqués ci-dessus.Having said this, the invention proposes to remedy to the various drawbacks of interior art mentioned above.

A cet effet, elle a pour objet un dispositif de progression sécurisée destiné à être placé le long d'une paroi, comprenant un élément allongé, notamment un câble, des moyens de fixation sur la paroi des deux extrémités dudit élément allongé, ainsi qu'au moins un ensemble de soutien intermédiaire dudit élément allongé, apte à être fixé dans ladite paroi, chaque ensemble de soutien comprenant un organe tournant, apte à être fixé dans ladite paroi, qui comporte plusieurs éléments en saillie radiale, ou bras, définissant deux à deux des renfoncements correspondants, chaque ensemble de soutien comprenant également un organe fixe solidaire dudit élément allongé, alors qu'il est prévu des moyens permettant de solidariser mutuellement en translation les organes fixe et tournant, quelle que soit la configuration angulaire de l'organe tournant, de sorte que, lors de la progression d'un utilisateur, un organe d'accrochage rapide puisse progresser autour dudit organe fixe, tout en étant reçu dans un renfoncement de l'organe tournant, de manière à provoquer la rotation de celui-ci.To this end, it relates to a device for secure progression intended to be placed along a wall, comprising an elongated element, in particular a cable, fixing means on the wall of the two ends of said elongated member, as well as at least one set of intermediate support of said elongated element, capable of being fixed in said wall, each support assembly comprising a rotating member, capable of being fixed in said wall, which has several radially projecting elements, or arm, defining two by two of the recesses correspondents, each support package including also a fixed member integral with said elongated element, while means are provided for securing mutually in translation the fixed and rotating members, whatever the angular configuration of the organ turning, so that as a user, a quick coupling device can progress around said fixed member, while being received in a recess in the rotating member, so that cause it to rotate.

According to other characteristics of the invention:
  • the fixed member is hollowed out with a track, extending in an arc, a track in which the arms of the rotating member are capable of advancing in rotation, while the means of securing in translation comprise at least one stud , which are provided with the walls of said track, capable of cooperating with at least one corresponding groove, formed in each arm;
  • whatever the angular configuration of the rotating member, at least one and, preferably, at least two arms is (are) permanently engaged with the track, in service;
  • the track is open on one side of the or each stud and is extended, on the other side of the or each stud, by a curved end portion;

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple non limitatif, et faite en se référant aux dessins annexés, dans lesquels :

  • la figure 1 est une vue schématique, illustrant l'implantation dans un tunnel d'un dispositif de progression sécurisée, conforme à l'invention ;
  • la figure 2 est une vue de face, illustrant de façon partielle un câble appartenant au dispositif de la figure 1, ainsi qu'un des ensembles de soutien intermédiaires de ce câble ;
  • la figure 3 est une vue en coupe selon la ligne III-III à la figure 2 ; et
  • les figures 4 à 7 sont des vues de face, analogues à la figure 2, illustrant trois phases de progression d'un organe d'accrochage rapide le long du câble précité.
The invention will be better understood on reading the description which follows, given solely by way of nonlimiting example, and made with reference to the appended drawings, in which:
  • Figure 1 is a schematic view illustrating the installation in a tunnel of a secure progression device, according to the invention;
  • Figure 2 is a front view, partially illustrating a cable belonging to the device of Figure 1, and one of the intermediate support assemblies of this cable;
  • Figure 3 is a sectional view along line III-III in Figure 2; and
  • Figures 4 to 7 are front views, similar to Figure 2, illustrating three phases of progression of a quick coupling member along the aforementioned cable.

La figure 1 illustre un dispositif de progression sécurisée conforme à l'invention, qui est agencé le long d'une paroi 2 d'un tunnel, représentée de façon schématique.Figure 1 illustrates a progression device secure according to the invention, which is arranged along of a wall 2 of a tunnel, represented so schematic.

Ce dispositif comprend un organe allongé, qui est par exemple un câble métallique 4. La nature métallique de cet organe allongé est avantageuse, dans la mesure où elle lui permet de résister, de façon satisfaisante, à un éventuel incendie se produisant dans le tunnel.This device comprises an elongated member, which is by example a metallic cable 4. The metallic nature of this elongated organ is advantageous, insofar as it allows to resist, satisfactorily, a possible fire occurring in the tunnel.

Ce câble métallique apporte en outre une solution satisfaisante au problème de dilatation, étant donné qu'il est réalisé d'un seul tenant. A cet égard, il convient de noter que deux dispositifs, permettant de régler de façon connue en soi la tension de ce câble, sont prévus aux deux extrémités de ce dernier.This metal cable also provides a solution satisfies the dilation problem, since it is made in one piece. In this regard, it is appropriate to note that two devices, allowing to adjust so known in itself the tension of this cable, are provided for both ends of the latter.

Le dispositif de progression sécurisée comporte également deux moyens de fixation 6, prévus aux extrémités longitudinales du câble 4. Ces moyens de fixation, de type connu en soi, sont par exemple des anneaux de fixation, des pièces mécano-soudées en forme de T, ou bien des pièces en acier pliées, munies de trous de fixation des ancres structurelles et d'un trou d'ancrage de l'extrémité du câble.The secure progression device includes also two fixing means 6, provided at the ends longitudinal of the cable 4. These fixing means, of the type known per se, are for example fixing rings, mechanically welded T-shaped parts, or parts made of bent steel, fitted with anchor fixing holes structural and an anchor hole at the end of the cable.

Il est enfin prévu différents moyens intermédiaires 8, permettant de soutenir le câble 4 entre ses deux extrémités. Ces ensembles de soutien 8 sont avantageusement répartis de façon régulière, selon des intervalles d prédéterminés, de sorte que l'utilisateur est à même de connaítre précisément la position qu'il occupe au sein du tunnel.Finally, various intermediate means 8 are provided, making it possible to support the cable 4 between its two ends. These support assemblies 8 are advantageously distributed regularly, according to predetermined intervals, so that the user is able to know precisely the position he occupies within the tunnel.

Les figures 2 et 3 illustrent, de façon plus précise, l'un des ensembles de soutien 8 représentés schématiquement sur la figure 1.Figures 2 and 3 illustrate, more precisely, one of the support assemblies 8 shown diagrammatically in figure 1.

Chaque ensemble de soutien 8 comprend ainsi un organe fixe 10, solidaire du câble, qui est par exemple formé de deux parties symétriques, mutuellemement réunies par tout moyen approprié, par exemple par vissage.Each support assembly 8 thus comprises a member fixed 10, integral with the cable, which is for example formed of two symmetrical parts, mutually joined by everything suitable means, for example by screwing.

Cet organe fixe est creusé, à ses deux extrémités longitudinales, d'ouvertures 12 débouchant respectivement dans une gorge médiane 14. Ainsi, le câble 4 s'étend à l'intérieur de ces ouvertures, ainsi que de cette gorge.This fixed member is hollowed out at its two ends longitudinal, of openings 12 opening respectively in a central groove 14. Thus, the cable 4 extends to inside these openings, as well as this groove.

A l'opposé de la gorge 14, à savoir sur la partie supérieure de la figure 2, une piste 16 est ménagée dans le corps de l'organe fixe 10. Vue de face, cette piste s'étend selon un arc de cercle dont le secteur angulaire est fonction de la nature et du diamètre du câble 4, de la dimension du mousqueton 38 et du diamètre de la roue 28, qui seront tous deux décrits dans ce qui suit.Opposite throat 14, namely on the part upper of Figure 2, a track 16 is provided in the body of the fixed member 10. Front view, this track extends according to an arc of a circle whose angular sector is depending on the nature and diameter of the cable 4, the dimension of the carabiner 38 and the diameter of the wheel 28, both of which will be described below.

Vue en coupe transversale, comme illustré à la figure 3, cette piste 16, qui est ouverte vers le haut, forme un col 18, du fait de la présence de deux tétons 20 faisant saillie l'un vers l'autre. Cette piste 16 s'évase ensuite, au-delà du col 18, de façon à former une portion d'extrémité bombée 22.Cross-sectional view, as illustrated in the figure 3, this track 16, which is open at the top, forms a col 18, due to the presence of two nipples 20 making protruding towards each other. This track 16 then flares, beyond the neck 18, so as to form a portion curved end 22.

L'ensemble de soutien 8 des figures 2 et 3 comprend également un organe tournant 24, qui comporte un axe 26, ici sensiblement horizontal, qui s'étend transversalement par rapport à la paroi 2. Cet axe 26 supporte une roue 28, qui est pourvue de différents bras 30, en saillie radiale, définissant deux à deux des renfoncements 32 correspondants.The support assembly 8 of Figures 2 and 3 includes also a rotating member 24, which has an axis 26, here substantially horizontal, which extends transversely relative to the wall 2. This axis 26 supports a wheel 28, which is provided with different arms 30, projecting radially, defining two by two of the recesses 32 correspondents.

L'extrémité libre de chaque bras 30, opposée à l'axe 26, présente un profil similaire à celui de la piste précitée 16. Ainsi, on retrouve un col 33, défini par deux rainures latérales 34, ainsi qu'une portion d'extrémité 36, analogues respectivement au col 18 et à la portion 22 de la piste 16.The free end of each arm 30, opposite the axis 26, has a profile similar to that of the runway supra 16. Thus, there is a collar 33, defined by two lateral grooves 34, as well as an end portion 36, analogous respectively to col 18 and portion 22 of the track 16.

L'utilisation du dispositif de progression sécurisée, décrit en référence aux figures 1 à 3, va maintenant être explicitée en référence aux figure 4 à 7.The use of the secure progression device, described with reference to Figures 1 to 3, will now be explained with reference to Figures 4 to 7.

L'utilisateur, tel un pompier, pénètre dans le tunnel par l'une de ses extrémités. Il dispose alors autour du câble 4 un organe d'accrochage rapide, encore dénommé organe de connexion, tel un mousqueton 38, au voisinage d'un des moyens 6 de fixation d'extrémité.The user, like a firefighter, enters the tunnel by one of its ends. He then has around the cable 4 a quick-attaching member, also known as connection member, such as a carabiner 38, in the vicinity one of the end fixing means 6.

Le pompier progresse alors de façon sécurisée, jusqu'à arriver à proximité du premier ensemble de soutien 8 (figure 4). On supposera, en référence aux figures 4 à 7, que le pompier se déplace de la gauche vers la droite. The firefighter then progresses safely, until get close to the first support set 8 (figure 4). We will assume, with reference to Figures 4 to 7, as the firefighter moves from left to right.

Comme le montre la figure 5, le mousqueton 38 entre tout d'abord en contact avec le bras 301, en prise avec la piste 16, qui lui est adjacent. L'avancée du pompier induit ainsi un mouvement de translation globale du mousqueton, selon la flèche F, ce qui provoque alors un mouvement correspondant de pivotement de la roue 28, selon la flèche f. As shown in Figure 5, the carabiner 38 first comes into contact with the arm 30 1 , engaged with the track 16, which is adjacent to it. The advance of the firefighter thus induces a global translational movement of the carabiner, according to arrow F, which then causes a corresponding pivoting movement of the wheel 28, according to arrow f.

De la sorte, à un stade intermédiaire de la progression (figure 6), le mousqueton 38 se trouve logé dans le renfoncement 321, délimité par le bras 301 précité, ainsi que par le bras 302 qui lui est adjacent. Il est à noter que ce mousqueton 38 se trouve en permanence lié au câble 4, lors de son avancée, étant donnée la présence de l'organe fixe 10.In this way, at an intermediate stage of progression (Figure 6), the carabiner 38 is housed in the recess 32 1 , delimited by the aforementioned arm 30 1 , as well as by the arm 30 2 which is adjacent to it. It should be noted that this carabiner 38 is permanently linked to the cable 4, during its advance, given the presence of the fixed member 10.

A cet égard, il convient de souligner qu'il n'est pas nécessaire de désolidariser le mousqueton 8 par rapport à ce câble 4, lors du franchissement de l'ensemble de soutien 8.In this regard, it should be emphasized that it is not necessary to separate the carabiner 8 from this cable 4, when crossing the support assembly 8.

Puis, au fur et à mesure de l'avancée du pompier, le mousqueton poursuit son mouvement de translation, qui continue à induire le pivotement correspondant de la roue 28. Lorsque le bras 301 est dégagé de la piste 16 (figure 7), le mousqueton se trouve libéré par rapport à la roue 28. Le pompier peut donc continuer à progresser en direction de l'ensemble de soutien suivant, alors que le mousqueton 38 se trouve toujours solidaire du câble 4.Then, as the fireman advances, the carabiner continues its translational movement, which continues to induce the corresponding pivoting of the wheel 28. When the arm 30 1 is released from the track 16 (FIG. 7), the carabiner is released relative to the wheel 28. The firefighter can therefore continue to progress towards the following support assembly, while the carabiner 38 is always secured to the cable 4.

Il est à noter que, quelle que soit la configuration angulaire de la roue 28, au moins deux bras 30 se trouvent en prise avec la piste 16, par coopération des tétons 20 avec les rainures 34.It should be noted that, whatever the configuration angle of the wheel 28, at least two arms 30 are located in contact with runway 16, by cooperation of nipples 20 with grooves 34.

De la sorte, l'organe fixe 10 se trouve en permanence solidarisé, en translation, avec l'organe mobile 24. Ceci garantit donc un soutien fiable du câble 4, par l'intermédiaire de chaque ensemble 8. In this way, the fixed member 10 is permanently located secured in translation with the movable member 24. This therefore guarantees reliable support for cable 4, by through each set 8.

Ainsi, dans l'exemple illustré, il est prévu sept bras 30, régulièrement répartis, de sorte que deux bras adjacents forment un angle α voisin de 51,4°. De la sorte, pour qu'au moins deux bras 30 se trouvent en permanence en prise avec la piste 16, cette dernière doit s'étendre selon un angle β supérieur ou égal au double de l'angle α, soit environ 102,8°.Thus, in the example illustrated, seven arms are provided 30, evenly distributed, so that two arms adjacent form an angle α close to 51.4 °. In this way, so that at least two arms 30 are permanently in taken with runway 16, the latter must extend as an angle β greater than or equal to twice the angle α, that is about 102.8 °.

A titre de variante, il est cependant possible de prévoir qu'un unique bras 30 de la roue 28 soit en permanence en prise avec l'organe fixe 10, quelle que soit la configuration angulaire de l'organe tournant 24. Dans cette optique, la piste 16 doit alors s'étendre selon un secteur angulaire supérieur ou égal à l'angle α précité, défini par deux bras 30 adjacents, à savoir environ 51,4° dans l'exemple illustré.As a variant, it is however possible to provide that a single arm 30 of the wheel 28 is in permanently engaged with the fixed member 10, whatever the angular configuration of the rotating member 24. In this optic, the track 16 must then extend according to a angular sector greater than or equal to the above-mentioned angle α, defined by two adjacent arms 30, namely approximately 51.4 ° in the example shown.

L'invention permet de réaliser les objectifs précédemment mentionnés.The invention achieves the objectives previously mentioned.

En effet, l'utilisateur est à même de progresser de façon rapide le long du dispositif conforme à l'invention, étant donné qu'il a uniquement à se munir d'un organe d'accrochage rapide, tel un mousqueton, qui est donc léger et peu encombrant. Par ailleurs, cette progression est particulièrement commode, notamment lors du franchissement des différents ensembles de soutien.Indeed, the user is able to progress from quickly along the device according to the invention, since he only has to bring an organ quick attachment, such as a carabiner, which is therefore light and space-saving. Furthermore, this progression is particularly convenient, especially when crossing different support packages.

En outre, il est à noter qu'un nombre élevé d'utilisateurs peuvent progresser en même temps le long du dispositif de l'invention, puisqu'il leur suffit de venir avec leur propre organe d'accrochage rapide. Ceci est à comparer avec l'art antérieur, faisant appel à des chariots agencés au préalable sur un rail.In addition, it should be noted that a high number users can progress along the device of the invention, since they just have to come with their own quick hook. This is at compare with the prior art, using carts arranged beforehand on a rail.

Enfin, le dispositif de l'invention n'est que peu sensible au phénomène de dilatation, dû à l'effet de la chaleur, étant donné que le câble métallique 4 auquel il est fait appel se trouve réalisé d'un seul tenant.Finally, the device of the invention is only slightly sensitive to the phenomenon of expansion, due to the effect of heat, since the metal cable 4 to which it is appealed is carried out in one piece.

En effet, dans ces conditions, la flèche du câble 4 se creuse entre les différents ensembles de soutien 8, ce qui ne gène pratiquement pas l'avancée du pompier. Ceci est à comparer avec l'art antérieur tirant parti d'un rail formé de plusieurs éléments, qui est donc sujet à des déformations sensibles sous l'effet de la chaleur, ce qui peut rendre la progression du chariot délicate, voire impossible.In fact, under these conditions, the deflection of the cable 4 is digs between the different support sets 8, which hardly hinders the advance of the firefighter. This is at compare with prior art taking advantage of a formed rail of several elements, which is therefore subject to significant deformation under the effect of heat, which can make the carriage progress difficult, even impossible.
