Description

Il est connu d'utiliser des dispositifs de sécurité pour des personnes se déplaçant sur des chemins de circulation placés à une hauteur importante du sol.It is known to use safety devices for people moving on traffic paths placed at a significant height from the ground.

Généralement, ces dispositifs comprennent, pour l'essentiel, un câble fixé à ses deux extrémités et tendu sensiblement parallèlement au chemin de circulation. Sur ce câble, peut coulisser un organe d'accrochage du type mousqueton relié par une sangle ou autre, à l'utilisateur.Generally, these devices essentially comprise a cable fixed at its two ends and stretched substantially parallel to the circulation path. On this cable, a hooking member of the carabiner type can slide, connected by a strap or the like, to the user.

Dans le cas d'un câble de longueur réduite, il n'est pas nécessaire de le soutenir par des organes supports intermédiaires disposés entre les points de fixation du câble. Il est donc possible, sans aucun problème, de faire coulisser le mousqueton sur la totalité de la longueur du câble.In the case of a cable of reduced length, it is not necessary to support it by intermediate support members arranged between the cable fixing points. It is therefore possible, without any problem, to slide the carabiner over the entire length of the cable.

Par contre, dans le cas d'un câble de grande longueur, ce qui est le plus fréquent, et pour réduire la flèche, il est nécessaire de disposer, généralement à intervalles réguliers, des organes supports pour soutenir le câble notamment en cas de chute de l'intervenant. On conçoit que ces organes supports intermédiaires interdisent le coulissement du mousqueton de manière continue sur la totalité de la longueur du câble. Or, compte-tenu du problème de sécurité recherchée, il n'est pas envisageable que l'utilisateur décroche, à chaque passage d'organes supports, le mousqueton.On the other hand, in the case of a very long cable, which is the most frequent, and to reduce the deflection, it is necessary to have, generally at regular intervals, support members to support the cable in particular in the event of a fall. of the speaker. It will be understood that these intermediate support members prevent the carabiner from sliding continuously over the entire length of the cable. However, given the security problem sought, it is not conceivable that the user takes down, with each passage of support members, the carabiner.

Pour résoudre ce problème, différentes solutions ont été proposées.To solve this problem, different solutions have been proposed.

Dans une forme de réalisation simplifiée, on a prévu de doubler la sangle de retenue et son mousqueton, de sorte qu'il est possible, pour l'utilisateur, de décrocher un des mousquetons au moment du passage de l'organe de soutien, le second mousqueton assurant la sécurité recherchée, étant donné que l'utilisateur est toujours maintenu au câble pr celui-ci. Lorsque le mousqueton, initialement désaccouplé, est accroché au dela de l'organe support, il suffit de décrocher l'autre mousqueton et procéder de la même façon pour le franchissement de l'organe.In a simplified embodiment, provision has been made to double the retaining strap and its carabiner, so that it is possible for the user to unhook one of the carabiners when the support member passes, the second carabiner ensuring the desired security, given that the user is always held by the pr cable. When the carabiner, initially uncoupled, is hooked beyond the support member, it suffices to unhook the other carabiner and proceed in the same way for crossing the member.

On conçoit que cette solution n'est pas rationnelle et n'offre pas une garantie de sécurité absolue, car elle dépend directement de la volonté de l'utilisateur de procéder ou non de cette façon.It is understood that this solution is not rational and does not offer an absolute security guarantee, because it depends directly on the will of the user to proceed or not in this way.

On a proposé également une solution au niveau de l'organe d'accrochage coopérant avec le câble. Un tel état de la technique peut être illustré par l'enseignement des brevets français N. 1 356 533 et 2 617 050. Dans l'un et l'autre de ces brevets, les organes d'accrochage sont équipés de moyens mécaniques permettant le franchissement des supports intermédiaires, sans déccrochage. Cependant, les solutions mécaniques proposées sont relativement complexes et par conséquent d'un coût de revient élevé.A solution has also been proposed at the level of the attachment member cooperating with the cable. Such a state of the art can be illustrated by the teaching of French patents N. 1,356,533 and 2,617,050. In both of these patents, the fastening members are equipped with mechanical means allowing the crossing of intermediate supports, without unhooking. However, the mechanical solutions proposed are relatively complex and consequently of a high cost price.

En outre, des phénomènees d'usure peuvent apparaître au niveau des pièces, de sorte que, la encore, la sécurité obtenue n'est pas absolue.In addition, wear phenomena can appear at the level of the parts, so that, again, the security obtained is not absolute.

L'invention s'est fixée pour but de remédier à ces inconvénients de manière simple et efficace.The object of the invention is to remedy these drawbacks in a simple and effective manner.

Le problème que se propose de résoudre l'invention est de créer un dispositif de sécurité qui se situe, non pas au niveau des moyens d'accrochage sur le câble, mais directement au niveau de la conception particulière des organes supports intermédiaires, en évitant ainsi, l'emploi d'organes rapportés de conception relativement compliquée.The problem which the invention proposes to solve is to create a safety device which is located, not at the level of the hooking means on the cable, but directly at the level of the particular design of the intermediate support members, thus avoiding , the use of relatively complicated designs.

Un tel problème est résolu en ce que chaque organe support intermédiaire présente un profil déterminé apte à assurer à la fois le soutien du câble et le passage du mousqueton sans désaccouplement avec ledit câble.Such a problem is solved in that each intermediate support member has a determined profile capable of ensuring both the support of the cable and the passage of the carabiner without uncoupling with said cable.

Plus particulièrement, le problème posé est résolu en ce que le profil (1a) (1b) (1c) de chaque organe support (1) est déterminé pour permettre le passage du mousqueton sans désaccouplement au fur et à mesure de son déplacement le long du câble (C), en soumettant ledit mousqueton à différents mouvements d'orientation angulaire, en combinaison avec ledit profil.More particularly, the problem posed is resolved in that the profile (1a) (1b) (1c) of each support member (1) is determined to allow the passage of the carabiner without uncoupling as it travels along the cable (C), by subjecting said carabiner to different angular movements, in combination with said profile.

Pour résoudre le problème posé du déplacement du mousqueton sans désaccouplement au niveau de chaque organe support, le profil particulier de ces derniers comprend une partie centrale d'appui et de retenue prolongée latéralement par un élément filiforme récourbé constituant une boucle ouverte.To solve the problem of moving the carabiner without uncoupling at each support member, the particular profile of the latter comprises a central support and retaining part extended laterally by a curved filiform element constituting an open loop.

Avantageusement, la partie centrale d'appui et de retenue se présente sous la forme d'un nez profilé formé transversalement en débordement d'une plaque agencée pour assurer la fixation de l'ensemble de l'organe support.Advantageously, the central support and retaining part is in the form of a profiled nose formed transversely in overflow from a plate arranged to ensure the fixing of the assembly of the support member.

Le nez profilé est formé très sensiblement d'une manière perpendiculaire à la plaque de fixation.The profiled nose is formed very substantially perpendicularly to the fixing plate.

L'élément filiforme recourbé constituant une boucle ouverte est disposé d'une manière symétrique au nez profilé.The curved filiform element constituting an open loop is arranged symmetrically to the profiled nose.

Compte-tenu du problème posé, dans une forme de réalisation préférée, le nez profilé présente, transversalement, un profil courbe, tandis que ses côtés latéraux sont disposés angulairement en étant raccordés par un large rayon de courbure, lesdits côtés étant prolongés par l'élément filiforme recourbé.Given the problem posed, in a preferred embodiment, the profiled nose has, transversely, a curved profile, while its lateral sides are arranged angularly by being connected by a wide radius of curvature, said sides being extended by the curved threadlike element.

En outre, l'élément filiforme est doublement recourbé dans un plan latéral et dans un plan transversal pour constituer, très sensiblement, un profil hélicoïdal, disposé de manière symétrique au nez, en constituant en combinaison avec les côtés latéraux, un chemin de guidage continu pour le passage du mousqueton, de manière à le soumettre aux différents mouvements successifs, par rapport au câble en décrivant très sensiblement une sinusoïde.In addition, the filiform element is doubly curved in a lateral plane and in a transverse plane to constitute, very substantially, a helical profile, arranged symmetrically at the nose, constituting in combination with the lateral sides, a continuous guide path. for the passage of the carabiner, so as to subject it to the various successive movements, relative to the cable, very substantially describing a sinusoid.

Le problème posé de pouvoir déplacer le mousqueton en le soumettant à différents mouvements angulaires successifs par rapport au câble, en décrivant tres sensiblement une sinusoïde, est résolu en ce que les différents organes supports sont fixés de sorte que le câble est positionné au centre du chemin de guidage délimité par l'élément filiforme et le nez.The problem posed of being able to move the carabiner by subjecting it to various successive angular movements relative to the cable, by very substantially describing a sinusoid, is solved in that the various support members are fixed so that the cable is positioned in the center of the path guide defined by the filiform element and the nose.

  • La figure 2 est une vue de face de l'organe support selon l'invention.
  • La figure 3 est une vue en plan correspondant à la figure 2.
  • La figure 4 est une vue arrière correspondant à la figure 2.
  • La figure 5 est une vue de profil correspondant à la figure 4.
The invention is set out below in more detail using the appended drawings, in which:
  • Figure 1 is a schematic front view showing an example of use of the safety device for raceway.
  • Figure 2 is a front view of the support member according to the invention.
  • FIG. 3 is a plan view corresponding to FIG. 2.
  • FIG. 4 is a rear view corresponding to FIG. 2.
  • FIG. 5 is a side view corresponding to FIG. 4.

Les figures 6 à 10 montrent, par différentes vues en perspectives, le passage du mousqueton en combinaison avec le profil de l'organe support et la déformation du câble.Figures 6 to 10 show, by different perspective views, the passage of the carabiner in combination with the profile of the support member and the deformation of the cable.

On voit, figure 1, un exemple d'application du dispositif de sécurité à un chemin de circulation (A) situé à une distance importante du sol. De manière connue, le dispositif de sécurité est établi essentiellement à partir d'un câble (C) fixé à chacune de ses extrémités, au moyen de tout élément approprié apte à maintenir le câble en tension. Compte-tenu de la longueur du câble, ce dernier coopère de préférence à intervalles réguliers avec des organes supports intermédiaires désignés dans leur ensemble, par (1). Ce câble est destiné à assurer la retenue de la personne devant se déplacer sur le chemin (A). Les organes supports assurent le soutien du câble en cas de chute de l'intervenant qui est relié au câble par une sangle ou autre, présentant, en bout, un mousqueton (M) qui peut coulisser le long du câble au fur et à mesure de son déplacement.We see, Figure 1, an example of application of the safety device to a traffic path (A) located at a significant distance from the ground. In known manner, the safety device is essentially established from a cable (C) fixed at each of its ends, by means of any suitable element capable of keeping the cable in tension. Given the length of the cable, the latter preferably cooperates at regular intervals with intermediate support members designated as a whole, by (1). This cable is intended to ensure the restraint of the person having to move on the path (A). The support members provide support for the cable in the event of a fall of the operator who is connected to the cable by a strap or the like, having, at the end, a carabiner (M) which can slide along the cable as and when its displacement.

Selon l'invention, chaque organe support intermédiaire (1) présente un profil déterminé apte à assurer à la fois, le soutien du câble (C), notamment en cas de chute, et le passage du mousqueton (M) sans désaccouplement de ce dernier avec ledit câble.According to the invention, each intermediate support member (1) has a determined profile capable of ensuring both the support of the cable (C), in particular in the event of a fall, and the passage of the carabiner (M) without uncoupling of the latter. with said cable.

Plus particulièrement, comme le montrent les figures 6 à 10 et comme il sera indiqué dans la suite de la description, le profil de chaque organe support (1) est déterminé pour permettre, de manière continue, le passage du mousqueton, au fur et à mesure de son déplacement le long du câble, en soumettant ledit mousqueton à différents mouvements d'orientai- ton angulaire en combinaison avec ledit profil.More particularly, as shown in Figures 6 to 10 and as will be indicated in the following description, the profile of each support member (1) is determined to allow, continuously, the passage of the carabiner, as and measuring its displacement along the cable, by subjecting said carabiner to different movements of angular orientation in combination with said profile.

Dans ce but, le profil de chaque organe support (1) est constitué d'une partie centrale d'appui et de retenue (1a) prolongée latéralement, par un élément filiforme (1b) recourbé pour constituer une boucle ouverte (1c). La partie centrale (1a) se présente sous forme d'un nez profilé, formé transversalement, en débordement d'une plaque (1d) agencée pour assurer la fixation de l'ensemble de l'organe support (1). A noter que cette fixation peut s'effectuer par tout moyen, par exemple, par boulonnage, soudure...For this purpose, the profile of each support member (1) consists of a central support and retaining part (1a) extended laterally, by a filiform element (1b) curved to form an open loop (1c). The central part (1a) is in the form of a profiled nose, formed transversely, projecting from a plate (1d) arranged to ensure the fixing of the whole of the support member (1). Note that this fixing can be done by any means, for example, by bolting, welding ...

Comme le montre la figure 4, le nez profilé (1 a) présente, transversalement, un profil courbe déterminé pour assurer la retenue du câble en cas de chute. Le nez (1a) est formé très sensiblement de manière perpendiculairement à la plaque de fixation (1d) (figure 5).As shown in Figure 4, the profiled nose (1a) has, transversely, a curved profile determined to ensure the retention of the cable in the event of a fall. The nose (1a) is formed very substantially perpendicularly to the fixing plate (1d) (Figure 5).

Les côtés latéraux (1a1) et (1a3) du nez sont disposés angulairement pour être raccordés par un large rayon de courbure (1 a2), lesdits côtés étant combinés avec l'élément filiforme (1 b) recourbé, formant boucle ouverte.The lateral sides (1a1) and (1a3) of the nose are angularly arranged to be connected by a wide radius of curvature (1 a2), said sides being combined with the curved filiform element (1b), forming an open loop.

On voit, aux figures des dessins, que l'élément filiforme (1 b) est doublement recourbé dans un plan latéral et dans un plan transversal pour constituer, très sensiblement, un profil hélicoïdal.It can be seen in the figures of the drawings that the filiform element (1b) is doubly curved in a lateral plane and in a transverse plane to constitute, very substantially, a helical profile.

Ce profil hélicoïdal (1 b) est disposé de manière symétrique au nez (1a) en constituant, en combinaison avec les côtés latéraux (1a1) (1a3) un chemin de guidage continu pour le passage du mousqueton (M) en le soumettant à différents mouvements angulaires successifs, par rapport au câble, de manière a décrire très sensiblement, une sinusoïde (figures 2 et 4).This helical profile (1b) is arranged symmetrically to the nose (1a) constituting, in combination with the lateral sides (1a1) (1a3) a continuous guide path for the passage of the carabiner (M) by subjecting it to different successive angular movements, relative to the cable, so as to describe very substantially, a sinusoid (Figures 2 and 4).

D'une manière importante, les diférents organes supports (1) sont fixés de sorte que le câble (C) est positionné au centre du chemin de guidage délimité par l'élément filiforme (1 b) et le nez (1 a).Importantly, the different support members (1) are fixed so that the cable (C) is positioned in the center of the guide path delimited by the filiform element (1b) and the nose (1a).

On décrit, ci-après, en se référant aux figures 6 à 10, le passage du mousqueton sans désaccouplement avec ledit câble, au niveau d'un organe support, compte-tenu du chemin de guidage hélicoïdal résultant du profil particulier dudit organe support.We describe below, with reference to Figures 6 to 10, the passage of the carabiner without uncoupling with said cable, at a support member, taking into account the helical guide path resulting from the particular profile of said support member.

La figure 6 représente le mousqueton (M) accroché au câble et avant le passage de l'organe support (1). Pour le passage du mousqueton, on oriente ce dernier angulairement (figure 7), pour permettre l'introduction dudit mousqueton dans l'ouverture de la boucle (1c). Le mousqueton est ensuite positionné, toujours en étant accouplé au câble et après un nouveau mouvement d'orientation angulaire, entre la boucle et le bord latéral profilé (1a1) du nez (figure. 8). On rabat angulairement le mousqueton pour le faire passer au dessus du profil courbe (1a2) du nez (figure 9). Le mousqueton peut ensuite être disposé au dela de l'autre côté latéral (1a3) du nez (figure 10) puis, après une nouvelle orientation angulaire, franchir l'autre boucle.Figure 6 shows the carabiner (M) attached to the cable and before the passage of the support member (1). For the passage of the carabiner, the latter is oriented angularly (Figure 7), to allow the introduction of said carabiner into the opening of the loop (1c). The carabiner is then positioned, still being coupled to the cable and after a new angular movement, between the loop and the profiled lateral edge (1a1) of the nose (Figure. 8). The carabiner is angularly folded down so that it passes over the curved profile (1a2) of the nose (Figure 9). The carabiner can then be placed beyond the other lateral side (1a3) of the nose (Figure 10) then, after a new angular orientation, cross the other loop.

Les avantages ressortent bien de la description, en particulier on souligne et on rappelle la simplicité de réalisation et la sécurité obtenue par un profil particulier adapté au niveau de chacun des organes supports permettant le passage sans désaccouplement du mousqueton et évitant l'emploi de moyens sophistiqués rapportés, permettant ainsi, à l'intervenant de se déplacer en toute sécurité sur tous les sites, d'un point à un autre, sur un axe horizontal.The advantages emerge clearly from the description, in particular the simplicity of construction and the security obtained by a particular profile adapted to each of the support members allowing and allowing the passage without uncoupling of the carabiner and avoiding the use of sophisticated means to be emphasized and recalled reported, allowing the operator to move safely on all sites, from one point to another, on a horizontal axis.
