Description

La présente invention concerne un dispositif de support pour un panneau de signalisation routière, destiné à être placé sur une glissière métallique.The present invention relates to a support device for a road sign, intended to be placed on a metal slide.

Ce dispositif peut être placé sur une glissière située au milieu et/ou de chaque côté d'une route ou d'une autoroute, notamment pour la signalisation temporaire, en cas de travaux ou d'accident par exemple.This device can be placed on a slide located in the middle and / or on each side of a road or highway, especially for temporary signage, in case of work or accident for example.

Un tel dispositif comprend typiquement une base destinée à être placée sur la glissière et recevant le panneau, la base comportant une face d'appui apte à reposer sur la glissière et au moins deux parties latérales destinées à être placées de part et d'autre de la glissière.Such a device typically comprises a base intended to be placed on the slideway and receiving the panel, the base comprising a bearing face adapted to rest on the slideway and at least two lateral parts intended to be placed on either side of the slideway. the slide.

Les dispositifs connus sont difficiles à mettre en place sur la glissière, car cela nécessite généralement une force importante de la part de l'utilisateur, ainsi qu'un outil tel qu'un marteau. Il est en effet indispensable de s'assurer d'une fixation satisfaisante du dispositif de support sur la glissière pour éviter que celui-ci ne soit arraché de la glissière, notamment lors du passage de camions qui produisent de grands mouvements d'air provoquant d'importants efforts sur le panneau. Le recours indispensable à un outil est contraignant et augmente le temps nécessaire pour mettre en place la signalisation temporaire. En outre, une fois le dispositif de support solidement monté sur la glissière, il est également difficile de le retirer, voire impossible sans outil.Known devices are difficult to implement on the slide, as this usually requires significant force on the part of the user, as well as a tool such as a hammer. It is indeed essential to ensure a satisfactory attachment of the support device on the slide to prevent it from being torn off the slide, especially when passing trucks that produce large air movements causing d important efforts on the panel. The essential use of a tool is binding and increases the time required to implement temporary signage. In addition, once the support device firmly mounted on the slide, it is also difficult to remove or impossible without tools.

Les dispositifs connus présentent également d'autres d'inconvénients :

  • ils sont spécifiquement conçus pour un unique type de glissière, et ne peuvent donc être placés sur une glissière d'un autre type, présentant une géométrie différente. Le nombre de dispositifs de support nécessaire, l'espace de stockage et les coûts correspondants en sont considérablement augmentés ;
  • ils sont souvent très lourds, ce qui complique leur maniement et leur mise en place par un unique opérateur ;
  • ils sont difficiles à transporter car de prise en main malaisée ;
  • il existe un risque d'arrachement causé par la circulation des véhicules.
The known devices also have other drawbacks:
  • they are specifically designed for a single type of slide, and therefore can not be placed on a slide of another type, having a different geometry. The number of support devices required, the storage space and the corresponding costs are considerably increased;
  • they are often very heavy, which complicates their handling and their implementation by a single operator;
  • they are difficult to transport because of difficult handling;
  • there is a risk of tearing caused by vehicle traffic.

Par ailleurs, le document FR 2 836 495 décrit un autre type de dispositif de support pour un panneau. Ce dispositif comprend une mâchoire pivotante pourvue d'un bras articulé qui, en position montée, vient en appui contre la glissière dans le cas d'une glissière métallique ou est placé en position escamotée dans le cas d'une glissière béton.In addition, the document FR 2,836,495 discloses another type of support device for a panel. This device comprises a pivoting jaw provided with an articulated arm which, in mounted position, bears against the slide in the case of a metal slide or is placed in the retracted position in the case of a concrete slide.

Ce dispositif présente l'avantage de pouvoir s'adapter à plusieurs profils de glissières (profil trapézoïdal d'une glissière béton ou profil ondulé d'une glissière métallique), mais elle conduit à un montage sur une glissière métallique particulièrement malaisé. En effet, l'opérateur doit à la fois maintenir le bras contre la glissière, par au-dessous, et basculer la poignée pour assurer le blocage du dispositif, par au-dessus.This device has the advantage of being able to adapt to several profiles of slides (trapezoidal profile of a concrete slide or corrugated profile of a metal slide), but it leads to a mounting on a particularly difficult metal slide. Indeed, the operator must both maintain the arm against the slide, from below, and tilt the handle to ensure the locking of the device, from above.

La présente invention vise à fournir un dispositif de support pour un panneau de signalisation routière qui puisse être facilement mis en place sur une glissière métallique, fixé et retiré, sans nécessiter d'outil. Un autre objectif de l'invention est de fournir un unique dispositif de support pouvant être adapté au moins à deux types de glissière métallique, notamment les glissières de type A et de type B existant sur les routes de France. L'invention vise également un dispositif de support pratique à transporter, et de poids réduit.The present invention aims to provide a support device for a road sign that can be easily set up on a metal slide, fixed and removed without requiring tools. Another object of the invention is to provide a single support device that can be adapted to at least two types of metal slide, including type A and type B slides existing on the roads of France. The invention also relates to a practical carrier device to carry, and reduced weight.

A cet effet, le dispositif de support selon l'invention comprend :

  • une base sur laquelle le panneau est destiné à être monté, comportant une face d'appui destinée à reposer sur la glissière et une première paroi latérale destinée à coopérer avec l'un des côtés de la glissière ;
  • un bras monté pivotant par rapport à la base autour d'un premier axe longitudinal, fixe par rapport à la base, entre une position extrême abaissée, dans laquelle le bras coopère avec l'autre côté de la glissière pour bloquer la glissière contre la première paroi latérale, et une position extrême relevée, dans laquelle le bras est écarté angulairement de la première paroi latérale, afin de permettre la mise en place du dispositif de support sur la glissière ou le retrait du dispositif de support hors de la glissière ;
  • des moyens d'actionnement du bras, comportant un levier dont une première extrémité est montée pivotante par rapport à la base autour d'un deuxième axe longitudinal, fixe par rapport à la base, et une bielle dont une première extrémité est articulée à la deuxième extrémité du levier autour d'un troisième axe longitudinal et dont la deuxième extrémité est articulée au bras autour d'un quatrième axe longitudinal, les troisième et quatrième axes étant mobiles par rapport à la base, les moyens d'actionnement étant agencés de sorte que le premier axe soit situé sous le quatrième axe et soit disposé - selon la direction transversale - entre le deuxième et le quatrième axes ;
  • des moyens de verrouillage du bras sensiblement dans sa position extrême abaissée.
For this purpose, the support device according to the invention comprises:
  • a base on which the panel is intended to be mounted, having a bearing face intended to rest on the slide and a first side wall intended to cooperate with one of the sides of the slide;
  • an arm pivotally mounted relative to the base about a first longitudinal axis, fixed relative to the base, between an extreme lowered position, wherein the arm cooperates with the other side of the slide to lock the slide against the first side wall, and an extreme raised position, wherein the arm is angularly spaced from the first side wall, to allow the introduction of the support device on the slide or the removal of the support device from the slide;
  • means for actuating the arm, comprising a lever whose first end is pivotally mounted relative to the base around a second longitudinal axis, fixed relative to the base, and a connecting rod whose first end is articulated to the second end of the lever about a third longitudinal axis and whose second end is articulated to the arm about a fourth longitudinal axis, the third and fourth axes being movable relative to the base, the actuating means being arranged so that the first axis is located under the fourth axis and is arranged - in the transverse direction - between the second and fourth axes;
  • locking means of the arm substantially in its lowered extreme position.

De plus, le bras comporte au moins une aile transversale fixe par rapport au bras, comprenant un évidement et une dent en saillie ménagés en regard de la première paroi latérale de la base, en position extrême abaissée du bras, et destinés à coopérer respectivement avec un bourrelet ou un creux longitudinal ménagés d'un côté de la glissière.In addition, the arm comprises at least one transverse wing fixed relative to the arm, comprising a recess and a protruding tooth arranged opposite the first side wall of the base, in the extreme lowered position of the arm, and intended to cooperate respectively with a bead or a longitudinal recess formed on one side of the slide.

Par exemple, le bras comporte deux ailes transversales sensiblement identiques, parallèles et espacées longitudinalement l'une de l'autre, et un fond reliant les deux ailes. Il est à noter que le bras et la ou les ailes forment une seule pièce.For example, the arm comprises two substantially identical transverse wings, parallel and spaced longitudinally from one another, and a bottom connecting the two wings. It should be noted that the arm and the wing (s) form a single piece.

En pratique, l'opérateur place la base sur la glissière alors que le bras est relevé, puis il lui suffit de déplacer à la main le levier pour provoquer le pivotement du bras vers sa position extrême abaissée. Les moyens de verrouillage permettent alors le maintien du bras sensiblement dans cette position pour assurer la fixation du dispositif de support sur la glissière.In practice, the operator places the base on the slide while the arm is raised, then it is sufficient to manually move the lever to cause pivoting of the arm to its lowered extreme position. The locking means then allow the maintenance of the arm substantially in this position to ensure the attachment of the support device on the slide.

Pour le retrait du dispositif de support hors de la glissière, l'opérateur, après avoir déverrouillé le dispositif, soulève le levier, ce qui provoque le pivotement du bras vers sa position extrême relevée. Il suffit alors de soulever le dispositif de support, qui n'est plus maintenu serré contre la glissière.For the removal of the support device from the slide, the operator, after unlocking the device, raises the lever, causing the pivoting arm to its raised extreme position. It is then sufficient to lift the support device, which is no longer held tight against the slide.

Ces manoeuvres sont très simples et rapides à exécuter, et le fonctionnement du système est intuitif. De plus, ces manoeuvres ne nécessitent ni effort ni d'outil particulier. La seule manoeuvre du levier par la poignée suffit à assurer le basculement du bras pivotant et le blocage du dispositif contre la glissière.These maneuvers are very simple and quick to execute, and the operation of the system is intuitive. In addition, these maneuvers require no effort or special tool. The only operation of the lever by the handle is sufficient to ensure the tilting of the pivoting arm and the locking of the device against the slide.

Selon une réalisation avantageuse, le levier et la bielle sont situés au-dessus de la base, le troisième axe étant disposé - selon la direction transversale - entre le deuxième et le quatrième axes, le levier et la bielle étant agencés de telle sorte que, en position de verrouillage du bras, le troisième axe est situé sous le deuxième et le quatrième axes, en butée contre la paroi supérieure de la base.According to an advantageous embodiment, the lever and the connecting rod are located above the base, the third axis being arranged - in the transverse direction - between the second and fourth axes, the lever and the connecting rod being arranged so that, in the locked position of the arm, the third axis is located under the second and fourth axes, in abutment against the upper wall of the base.

En d'autres termes, lorsque le levier et la bielle sont sensiblement alignés, le bras est en position extrême abaissée et le troisième axe est situé à proximité mais à distance de la paroi supérieure de la base. Ainsi, le verrouillage est obtenu en abaissant encore le levier, jusqu'à ce que le troisième axe vienne en contact avec la paroi supérieure de la base, ce qui constitue une butée limitant le déplacement. Pour déverrouiller le dispositif, l'opérateur doit relever le levier. Ce déplacement nécessite de déformer légèrement l'ensemble constitué du dispositif de support et de la glissière, pour passer au-delà du point dur - c'est-à-dire lorsque le levier et la bielle sont alignés. Le déverrouillage nécessite ainsi un effort qui est calibré : l'effort est suffisamment faible pour pouvoir être fourni facilement par l'opérateur et suffisamment important pour écarter tout risque de déverrouillage intempestif.In other words, when the lever and the connecting rod are substantially aligned, the arm is in the extreme lowered position and the third axis is located near but at a distance from the upper wall of the base. Thus, locking is achieved by further lowering the lever, until the third axis comes into contact with the upper wall of the base, which is a stop limiting displacement. To unlock the device, the operator must raise the lever. This movement requires slightly deforming the assembly consisting of the support device and the slide, to pass beyond the hard point - that is to say when the lever and the connecting rod are aligned. The unlocking thus requires a force that is calibrated: the force is low enough to be easily supplied by the operator and large enough to avoid any risk of inadvertent unlocking.

Un avantage supplémentaire de cette structure réside dans le fait que le dispositif de support est insensible aux vibrations liées au passage des véhicules.An additional advantage of this structure lies in the fact that the support device is insensitive to vibrations related to the passage of vehicles.

Le dispositif de support peut en outre comprendre une deuxième paroi latérale fixée à la face d'appui et destinée à coopérer avec l'autre côté de la glissière. La hauteur de la deuxième paroi latérale est par exemple inférieure aux deux tiers de la hauteur de la première paroi latérale, afin de permettre un maintien satisfaisant du dispositif sur la glissière sans toutefois gêner sa mise en place sur la glissière.The support device may further comprise a second side wall fixed to the bearing face and intended to cooperate with the other side of the slide. The height of the second side wall is for example less than two thirds of the height of the first side wall, to allow a satisfactory maintenance of the device on the slide without interfering with its establishment on the slide.

Selon une réalisation possible, la première et/ou la deuxième paroi latérale est sensiblement plane, et disposée longitudinalement de façon orthogonale à la face d'appui.According to one possible embodiment, the first and / or the second lateral wall is substantially flat, and disposed longitudinally orthogonal to the bearing face.

Par ailleurs, le dispositif de support peut comprendre au moins un crochet solidaire de la base, dont l'ouverture est située sous la face d'appui, le crochet étant agencé pour coopérer avec le rebord supérieur d'au moins un type de glissière. Avantageusement, la hauteur du crochet est suffisamment petite pour que, lorsque le dispositif est monté sur une glissière d'un autre type, le crochet soit situé au-dessus de ladite glissière, à distance de celle-ci.Furthermore, the support device may comprise at least one hook integral with the base, whose opening is located under the bearing face, the hook being arranged to cooperate with the upper rim of at least one type of slide. Advantageously, the height of the hook is sufficiently small so that, when the device is mounted on a slide of another type, the hook is located above said slide, at a distance from the latter.

Selon une réalisation possible, la dent en saillie comporte un bord supérieur et un bord inférieur convergeant l'un vers l'autre en direction de la première paroi latérale, en position extrême abaissée du bras, au moins l'un des bords comportant une première partie inclinée par rapport à l'horizontale d'un angle β, prolongée, lorsque l'on s'éloigne de la première paroi latérale, par une deuxième partie inclinée par rapport à l'horizontale d'un angle γ inférieur à β.According to one possible embodiment, the projecting tooth has an upper edge and a lower edge converging towards one another towards the first side wall, in the extreme lowered position of the arm, at least one of the edges comprising a first part inclined relative to the horizontal of an angle β, extended, when one moves away from the first side wall, by a second portion inclined relative to the horizontal of an angle γ less than β.

La figure 1 représente un dispositif de support 1, qui est par exemple réalisé à partir de plaques de tôle découpées, pliées et soudées.Figure 1 shows a support device 1, which is for example made from sheet metal plates cut, folded and welded.

Le dispositif de support 1 comprend une base 2, formée ici d'un tube creux de section carrée. Un poteau 3, également formé d'un tube creux de section carrée et pourvu d'un fond 4 fermé, est fixé à une première extrémité de la base 2, orthogonalement à celle-ci. Le poteau 3 est destiné à recevoir le mât d'un panneau de signalisation routière.The support device 1 comprises a base 2, formed here of a hollow tube of square section. A post 3, also formed of a hollow tube of square section and provided with a closed bottom 4, is attached to a first end of the base 2, orthogonally thereto. The post 3 is intended to receive the mast of a road sign.

Pour simplifier, on décrit le dispositif de support 1 dans la position qu'il occupe lorsqu'il est mis en place sur une glissière : le poteau 3 est alors sensiblement vertical et la base 2 sensiblement horizontale et orthogonale à la direction générale de la glissière. On définit la direction verticale z, par rapport à laquelle sont utilisés les termes « supérieur », « inférieur », « hauteur », et la direction transversale y comme la direction dans laquelle s'étend la base 2, par rapport à laquelle sont utilisés les termes « latéral », « côté », « largeur ». Enfin, on définit la direction longitudinale x comme la direction orthogonale aux directions verticale et transversale (voir figure 1), qui correspond à la direction dans laquelle s'étend la glissière.For simplicity, the support device 1 is described in the position it occupies when it is put in place on a slideway: the pole 3 is then substantially vertical and the base 2 substantially horizontal and orthogonal to the general direction of the slideway . We define the vertical direction z, with respect to which are used the terms "upper", "lower", "height", and the transverse direction y as the direction in which the base 2 extends, with respect to which are used the terms "lateral", "side", "width". Finally, the longitudinal direction x is defined as the direction orthogonal to the vertical and transverse directions (see FIG. 1), which corresponds to the direction in which the slideway extends.

A sa partie extrême opposée au poteau 3, la base 2 comprend une première paroi latérale 5, sensiblement plane et s'étendant orthogonalement à la direction transversale y. La base 2 comporte également, à sa deuxième extrémité, une deuxième paroi latérale 6, sensiblement plane et parallèle à la première paroi latérale 5. Les deux parois latérales 5, 6 sont situées sous la base 2 et sont fixées à celle-ci, en étant espacées l'une de l'autre d'une distance d. La hauteur de la deuxième paroi latérale 6 est inférieure à la hauteur de la première paroi latérale 5, et par exemple voisine du tiers. Les longueurs des parois latérales 5, 6 (selon la direction x) sont suffisantes pour permettre un maintien satisfaisant du dispositif de support 1 sur une glissière. Ces longueurs, qui sont ici sensiblement identiques, sont par exemple comprises entre 10 et 20 cm.At its end opposite to the post 3, the base 2 comprises a first lateral wall 5, substantially flat and extending orthogonally to the transverse direction y. The base 2 also comprises, at its second end, a second lateral wall 6, substantially flat and parallel to the first side wall 5. The two side walls 5, 6 are located under the base 2 and are fixed thereto, being spaced from each other by a distance d. The height of the second side wall 6 is less than the height of the first side wall 5, and for example close to one-third. The lengths of the side walls 5, 6 (in the x direction) are sufficient for allow a satisfactory maintenance of the support device 1 on a slide. These lengths, which are here substantially identical, are for example between 10 and 20 cm.

La face inférieure de la base 2 située entre les parois latérales 5, 6 forme une face d'appui 7 destinée à reposer sur la glissière. Selon une réalisation possible, les parois latérales 5, 6 sont formées par les branches d'une tôle pliée en U, dont le fond est soudé sous la base 2 et constitue la face d'appui 7. Des pattes 8 s'étendant orthogonalement à la direction x font saillie depuis le fond de cette tôle en U, vers le haut, de part et d'autre dudit fond (selon la direction x). Le bord supérieur des pattes 8 est de préférence au même niveau que la face supérieure 28 de la base 2.The lower face of the base 2 located between the side walls 5, 6 forms a bearing face 7 intended to rest on the slide. According to one possible embodiment, the side walls 5, 6 are formed by the branches of a U-folded sheet, the bottom of which is welded under the base 2 and constitutes the bearing face 7. Tabs 8 extending orthogonally to the direction x project from the bottom of the U-shaped sheet, upwards, on either side of said bottom (in the x direction). The upper edge of the tabs 8 is preferably at the same level as the upper face 28 of the base 2.

En outre, il peut être prévu une pièce de renfort en coin 9 placée entre la base 2 et la première paroi latérale 5.In addition, there may be provided a corner reinforcing piece 9 placed between the base 2 and the first side wall 5.

Le dispositif de support 1 comporte également un bras 10, formé d'une tôle pliée en U, comprenant un fond 11 et deux ailes latérales 12 sensiblement identiques et orthogonales au fond 11.The support device 1 also comprises an arm 10, formed of a U-folded sheet, comprising a bottom 11 and two lateral wings 12 substantially identical and orthogonal to the bottom 11.

Chaque aile 12 présente une forme sensiblement rectangulaire comportant un évidement 13 débouchant dans le bord de l'aile 12 opposé au bord de cette aile 12 lié au fond 11. Sont ainsi définis, de part et d'autre de cet évidement 13, d'une part une langue 14, sensiblement rectangulaire, et d'autre part une dent 15.Each wing 12 has a substantially rectangular shape with a recess 13 opening into the edge of the flange 12 opposite the edge of the flange 12 bonded to the bottom 11. Are thus defined, on either side of this recess 13, of partly a tongue 14, substantially rectangular, and secondly a tooth 15.

Le bras 10 est monté sur la base 2 de façon pivotante autour d'un premier axe 16 longitudinal. Dans la réalisation représentée, le premier axe 16 est formé par deux tiges engagées chacune dans la partie extrême libre d'une langue 14 et la patte 8 correspondante. La distance entre les ailes 12 est ainsi sensiblement égale à la longueur des parois latérales 5, 6. Le premier axe 16 est situé en partie supérieure du bras 10.The arm 10 is mounted on the base 2 pivotally about a first longitudinal axis 16. In the embodiment shown, the first axis 16 is formed by two rods each engaged in the free end portion of a tongue 14 and the corresponding tab 8. The distance between the wings 12 is thus substantially equal to the length of the side walls 5, 6. The first axis 16 is located in the upper part of the arm 10.

Le bras 10 peut donc pivoter entre :

  • une position extrême abaissée (figures 1, 3, 5), dans laquelle le fond 11 est sensiblement vertical et orthogonal à la direction y, les ailes 12 étant dirigées vers la première paroi latérale 5. Dans cette position, le fond 11 est donc sensiblement parallèle à la première paroi latérale 5. Il est de plus espacé de la deuxième paroi latérale 6, à l'opposé du poteau 3 (voir figures 3 et 5). Par ailleurs, le bord libre 17 des dents 15 est situé - selon la direction y - entre les parois latérales 5, 6, et à distance de chacune d'entre elles ;
  • et une position extrême relevée (figures 2, 4), dans laquelle le fond 11 du bras 10 est incliné d'un angle α par rapport à la verticale. L'angle α est suffisamment important pour que le bord libre 17 des dents 15 soit situé - selon la direction y - au-delà de la deuxième paroi latérale 6 et non plus entre les parois latérales 5, 6. Ceci permet de faciliter le retrait du dispositif de support 1 hors d'une glissière, comme on le verra plus loin. α est par exemple compris entre 20 et 40°.
The arm 10 can therefore rotate between:
  • an extreme lowered position (Figures 1, 3, 5), wherein the bottom 11 is substantially vertical and orthogonal to the direction y, the flanges 12 being directed towards the first side wall 5. In this position, the bottom 11 is substantially parallel to the first side wall 5. It is further spaced from the second side wall 6, opposite the pole 3 (see Figures 3 and 5). Furthermore, the free edge 17 of the teeth 15 is located - in the direction y - between the side walls 5, 6, and at a distance from each of them;
  • and an extreme raised position (Figures 2, 4), wherein the bottom 11 of the arm 10 is inclined at an angle α relative to the vertical. The angle α is large enough so that the free edge 17 of the teeth 15 is located - in the direction y - beyond the second side wall 6 and no longer between the side walls 5, 6. This facilitates the withdrawal. the support device 1 out of a slide, as will be seen later. α is for example between 20 and 40 °.

La dent 15 de chaque aile 12 comporte un bord supérieur 18 (adjacent à l'évidement 13) et un bord inférieur 19 convergeant l'un vers l'autre depuis le fond 11 du bras 10 en direction du bord libre 17. Les bords 18, 19 sont sensiblement symétriques et comportent une première partie 20 qui s'étend depuis le bord libre 17 et est inclinée par rapport à l'horizontale (lorsque le bras est en position extrême abaissée) d'un angle β. La première partie 20 est prolongée en direction du fond 11 par une deuxième partie 21 qui est inclinée par rapport à l'horizontale (lorsque le bras est en position extrême abaissée) d'un angle γ inférieur à β. Entre les première et deuxième parties 20, 21 est donc définie une zone d'angle arrondie 22. Les angles β et γ sont adaptés à la géométrie des glissières existantes, comme on le verra plus loin. Ainsi, β est de l'ordre de 25 à 35°, et γ est de l'ordre de 5 à 15°.The tooth 15 of each wing 12 has an upper edge 18 (adjacent to the recess 13) and a lower edge 19 converging towards each other from the bottom 11 of the arm 10 towards the free edge 17. The edges 18 , 19 are substantially symmetrical and comprise a first portion 20 which extends from the free edge 17 and is inclined relative to the horizontal (when the arm is in the extreme lowered position) by an angle β. The first portion 20 is extended towards the bottom 11 by a second portion 21 which is inclined relative to the horizontal (when the arm is in the extreme lowered position) by an angle γ less than β. Between the first and second parts 20, 21 is therefore defined a rounded corner area 22. The angles β and γ are adapted to the geometry of the existing slides, as will be seen later. Thus, β is of the order of 25 to 35 °, and γ is of the order of 5 to 15 °.

Le dispositif de support 1 comporte en outre des moyens d'actionnement permettant à un opérateur de faire pivoter le bras 10.The support device 1 further comprises actuating means enabling an operator to rotate the arm 10.

Ces moyens comprennent un levier 22 et une bielle 23, tous deux s'étendant sensiblement dans un plan orthogonal à la direction x et médian de la base 2, en étant situés au-dessus de la base 2. Une première extrémité du levier 22 est montée pivotante par rapport à la base 2 autour d'un deuxième axe longitudinal 24, tandis qu'une deuxième extrémité du levier 22 est montée pivotante par rapport à la bielle 23 autour d'un troisième axe longitudinal 25. Enfin, la deuxième extrémité de la bielle 23 est montée pivotante par rapport au bras 10 autour d'un quatrième axe longitudinal 26.These means comprise a lever 22 and a connecting rod 23, both extending substantially in a plane orthogonal to the x and median direction of the base 2, being situated above the base 2. A first end of the lever 22 is pivotally mounted relative to the base 2 about a second longitudinal axis 24, while a second end of the lever 22 is pivotally mounted relative to the connecting rod 23 about a third longitudinal axis 25. Finally, the second end of the connecting rod 23 is pivotally mounted relative to the arm 10 around a fourth longitudinal axis 26.

Le quatrième axe 26 est formé par une tige engagée dans la bielle 23 et dans des languettes 27 faisant saillie du fond 11 du bras 10, en direction du poteau 3, de part et d'autre de la bielle 23 (selon la direction longitudinale) et comportant chacune une partie orthogonale à l'axe x. Deux entretoises cylindriques (non représentées) sont engagées autour de la tige, de part et d'autre de la bielle 23, pour empêcher le déplacement selon x de la bielle 23 par rapport au bras 10. Le quatrième axe 26 est plus éloigné du poteau 3 (selon la direction y) que le premier axe 16 dans toutes les positions possibles du bras 10.The fourth axis 26 is formed by a rod engaged in the rod 23 and in tongues 27 protruding from the bottom 11 of the arm 10, towards the pole 3, on either side of the rod 23 (in the longitudinal direction) and each having a portion orthogonal to the x-axis. Two cylindrical spacers (not shown) are engaged around the rod, on either side of the connecting rod 23, to prevent the displacement along x of the connecting rod 23 relative to the arm 10. The fourth axis 26 is farther from the post 3 (in the y direction) as the first axis 16 in all possible positions of the arm 10.

Le deuxième axe 24 est porté par une pièce 29 soudée sur la base 2. Il est situé sensiblement à mi distance entre le poteau 3 et la deuxième paroi latérale 6, et à une faible distance (par exemple inférieure à 5 cm) de la face supérieure 28 de la base 2.The second axis 24 is carried by a part 29 welded to the base 2. It is located substantially midway between the post 3 and the second side wall 6, and at a short distance (for example less than 5 cm) from the face upper 28 of the base 2.

Quant au troisième axe 25, il est situé entre les deuxième et quatrième axes 24, 26, sensiblement dans le même plan vertical que le premier axe 16. La longueur du levier 22 (selon la direction y) est nettement supérieure à celle de la bielle 23, par exemple supérieure au triple.As for the third axis 25, it is located between the second and fourth axes 24, 26, substantially in the same vertical plane as the first axis 16. The length of the lever 22 (in the y direction) is significantly greater than that of the connecting rod 23, for example greater than triple.

Avantageusement, le levier 22 peut comporter une poignée 30, qui facilite le transport du dispositif de support 1 et l'actionnement du levier 22.Advantageously, the lever 22 may comprise a handle 30, which facilitates the transport of the support device 1 and the actuation of the lever 22.

Enfin, le dispositif de support 1 comporte deux crochets 31 transversaux, fixés sous la base 2, entre les parois latérales 5, 6, de part et d'autre de la base 2 selon la direction longitudinale. Par exemple, les crochets 31 sont situés dans le prolongement vertical des pattes 8. Chaque crochet 31 présente une ouverture tournée vers le bras 10, et présente, dans la réalisation représentée, une forme en L.Finally, the support device 1 comprises two transverse hooks 31, fixed under the base 2, between the side walls 5, 6, on either side of the base 2 in the longitudinal direction. For example, the hooks 31 are located in the vertical extension of the tabs 8. Each hook 31 has an opening facing the arm 10, and has, in the embodiment shown, an L-shaped.

On se réfère à présent aux figures 2 et 3.Reference is now made to Figures 2 and 3.

Sur ces figures est représentée une glissière 32 d'un premier type (dit « type A »), qui comporte deux ondulations définissant d'un premier côté de la glissière d'une part un bourrelet central longitudinal, formant une face verticale 33 sensiblement plane, et d'autre part deux creux longitudinaux. Symétriquement, le deuxième côté de la glissière 32 comporte donc d'une part un creux central longitudinal 34 limité par des parois supérieure 35 et inférieure 36 convergeant l'une vers l'autre en direction de la face verticale 33 selon un angle (par rapport à l'horizontale) voisin de β, et d'autre part deux bourrelets longitudinaux présentant une section globalement triangulaire et un sommet 37 arrondi. Le rebord supérieur 38 de la glissière 32 est situé sensiblement dans le même plan vertical que la face verticale 33.In these figures is represented a slide 32 of a first type (called "type A"), which comprises two corrugations defining a first side of the slide on the one hand a longitudinal central bead, forming a vertical face 33 substantially flat , and on the other hand two longitudinal hollows. Symmetrically, the second side of the slideway 32 therefore comprises on the one hand a longitudinal central cavity 34 bounded by upper and lower walls 36 converging towards each other in the direction of the vertical face 33 at an angle (relative to horizontally) adjacent to β, and secondly two longitudinal beads having a generally triangular section and a rounded vertex 37. The upper edge 38 of the slide 32 is located substantially in the same vertical plane as the vertical face 33.

Pour la mise en place du dispositif de support 1 sur la glissière 32, un opérateur soulève le levier 22 par la poignée 30, provoquant de ce fait le pivotement du bras 10 vers sa position extrême relevée. Le dispositif 1 est alors placé sur la glissière 32, de sorte que la face d'appui 7 repose sur la glissière 2 et que les parois latérales 5, 6 soient placées de part et d'autre de la glissière 32.For the establishment of the support device 1 on the slide 32, an operator lifts the lever 22 by the handle 30, thereby causing the pivoting arm 10 to its raised extreme position. The device 1 is then placed on the slide 32, so that the bearing face 7 rests on the slide 2 and the side walls 5, 6 are placed on either side of the slide 32.

Bien entendu, les dimensions du dispositif 1 sont adaptées à celles de la glissière 32. Ainsi, la distance d séparant les parois latérales 5, 6 est légèrement supérieure à la largeur de la glissière 32, afin de permettre la mise en place du dispositif 1 tout en assurant un maintien satisfaisant en position. En effet, en position montée, la première paroi latérale 5 est sensiblement en contact d'une part avec la face verticale 33 de la glissière 32 et avec le rebord supérieur 38, tandis que la deuxième paroi latérale 6 est sensiblement en contact avec le sommet 37 du bourrelet supérieur. La deuxième paroi 6 présente donc une hauteur suffisamment grande pour être en regard dudit sommet 37, et suffisamment petite pour ne pas gêner la mise en place du dispositif 1 sur la glissière, qui peut s'effectuer par pivotement autour d'un axe longitudinal.Of course, the dimensions of the device 1 are adapted to those of the slide 32. Thus, the distance d separating the side walls 5, 6 is slightly greater than the width of the slide 32, to allow the introduction of the device 1 while ensuring a satisfactory maintenance in position. Indeed, in the mounted position, the first side wall 5 is substantially in contact with the vertical face 33 of the slide 32 and with the upper rim 38, while the second lateral wall 6 is substantially in contact with the top. 37 of the upper bead. The second wall 6 thus has a height large enough to be opposite said top 37, and small enough not to interfere with the introduction of the device 1 on the slide, which can be performed by pivoting about a longitudinal axis.

En outre, la hauteur des crochets 31 est suffisamment faible pour que ceux-ci soit situés au-dessus de la glissière 32 sans gêner le positionnement du dispositif 1 (les crochets 31 n'étant pas indispensables au maintien dans ce cas).In addition, the height of the hooks 31 is small enough that they are located above the slide 32 without interfering with the positioning of the device 1 (the hooks 31 are not essential for maintaining in this case).

L'opérateur appuie alors sur le levier 22, ce qui a pour effet de le faire pivoter autour du deuxième axe 24. En conséquence, la bielle 23 pivote autour des axes 25, 26 et tend à s'aligner avec le levier 22, le quatrième axe 26 s'éloigne du poteau 3, et donc le bras 10 pivote autour du premier axe 16 et s'abaisse, les dents 15 venant s'engager dans le creux 34 de la glissière.The operator then presses the lever 22, which has the effect of rotating it about the second axis 24. As a result, the rod 23 pivots about the axes 25, 26 and tends to align with the lever 22, the fourth axis 26 moves away from the pole 3, and thus the arm 10 pivots about the first axis 16 and lowers, the teeth 15 coming into the recess 34 of the slide.

La géométrie de l'ensemble est agencée pour que, lorsque le levier 22 et la bielle 23 sont sensiblement alignés, le bras 10 soit dans sa position extrême abaissée. Le troisième axe 25 est alors situé à proximité mais à distance de la face supérieure 28 de la base 2. Dans cette position, la distance entre les deuxième et quatrième axes 24, 27 est maximale, et les dents 15 sont poussées contre la glissière 32, le dispositif 1 et la glissière 32 étant légèrement déformés élastiquement.The geometry of the assembly is arranged so that, when the lever 22 and the rod 23 are substantially aligned, the arm 10 is in its extreme lowered position. The third axis 25 is then located near but at a distance from the upper face 28 of the base 2. In this position, the distance between the second and fourth axes 24, 27 is maximum, and the teeth 15 are pushed against the slide 32 , the device 1 and the slide 32 being slightly elastically deformed.

L'opérateur continue ensuite d'appuyer sur le levier 22, jusqu'à venir en butée dans ce mouvement contre la face supérieure 28 de la base 2. La distance D a alors légèrement diminué et le bras 10 s'est légèrement relevé (figure 3).The operator then continues to press the lever 22, until it abuts in this movement against the upper face 28 of the base 2. The distance D has then slightly decreased and the arm 10 is slightly raised (FIG. 3).

Dans cette position, le dispositif 1 est maintenu de façon satisfaisante sur la glissière 32 par la coopération entre les parois latérales 5, 6 et les côtés de la glissière 32, ainsi que par la coopération entre les premières parties 20 des bords supérieur 18 et inférieur 19 des dents 15 et les parois supérieure 35 et inférieure 36 du creux 34 de la glissière 32. Ainsi, dans cette position, chaque aile 12 s'étend sensiblement verticalement, et la dent 15 de chaque aile 12 est en contact et en appui contre la glissière 32, du côté opposé à la première paroi latérale 5.In this position, the device 1 is maintained satisfactorily on the slide 32 by the cooperation between the side walls 5, 6 and the sides of the slide 32, as well as by the cooperation between the first parts 20 of the upper and lower edges 18 19 teeth 15 and the walls 35 upper and lower 36 of the hollow 34 of the slide 32. Thus, in this position, each wing 12 extends substantially vertically, and the tooth 15 of each wing 12 is in contact and bears against the slide 32, the opposite side at the first side wall 5.

De plus, le dispositif 1 est verrouillé sur la glissière 32. En effet, pour relever le bras 10, il faut repasser par la position sensiblement alignée du levier 22 et de la bielle 23, c'est-à-dire augmenter la distance D, et provoquer une déformation élastique de l'ensemble. Or, le dispositif 1 est dimensionné pour que ceci soit impossible sans action humaine, par exemple uniquement sous l'effet des efforts s'exerçant sur le panneau lorsque le dispositif 1 est placé au bord d'une route ou d'une autoroute.In addition, the device 1 is locked on the slide 32. In fact, to raise the arm 10, it is necessary to go back through the substantially aligned position of the lever 22 and the connecting rod 23, that is to say, to increase the distance D , and cause elastic deformation of the whole. However, the device 1 is dimensioned so that this is impossible without human action, for example only under the effect of the forces exerted on the panel when the device 1 is placed at the edge of a road or highway.

En revanche, un opérateur peut tout à fait soulever le levier 2 sans effort excessif, pour retirer le dispositif 1 hors de la glissière 32. Lorsqu'un opérateur soulève ou tient le dispositif 1 par la poignée 30, notamment lors du transport, le bras 10 est automatiquement déplacé vers sa position relevée du fait du poids de la base 2.On the other hand, an operator can quite lift the lever 2 without excessive effort, to remove the device 1 from the slide 32. When an operator raises or holds the device 1 by the handle 30, especially during transport, the arm 10 is automatically moved to its raised position due to the weight of the base 2.

Il est à noter que la fin du mouvement de déplacement du levier 22 vers la base 2 nécessite un petit effort, ce qui est souhaitable pour indiquer à l'opérateur qu'il arrive en position verrouillée. Cet effort est toutefois relativement faible, de sorte que tout opérateur puisse le fournir.It should be noted that the end of the movement of movement of the lever 22 towards the base 2 requires a small effort, which is desirable to indicate to the operator that he arrives in the locked position. This effort is however relatively small, so that any operator can provide it.

On se réfère à présent aux figures 4 et 5.Reference is now made to Figures 4 and 5.

Sur ces figures est représentée une glissière 32' d'un second type (dit « type B »), qui comporte également deux ondulations, mais de forme différente par rapport à la glissière 32 du premier type.In these figures is shown a slide 32 'of a second type (called "type B"), which also has two corrugations, but of different shape with respect to the slide 32 of the first type.

Ainsi, notamment, les bourrelets longitudinaux ménagés du deuxième côté de la glissière 32' présentent une section globalement trapézoïdale comportant un sommet 37' sensiblement plan et vertical. En outre, les parois supérieure 35' et inférieure 36' du creux central 34' sont inclinées d'un angle (par rapport à l'horizontale) plus faible que l'angle β. Enfin, le rebord supérieur 38' est situé à distance du plan vertical défini par la face verticale 33', vers le deuxième côté de la glissière 32'.Thus, in particular, the longitudinal beads formed on the second side of the slide 32 'have a generally trapezoidal section having a substantially plane and vertical apex 37'. In addition, the upper walls 35 'and lower 36' of the central recess 34 'are inclined at an angle (relative to the horizontal) lower than the angle β. Finally, the upper flange 38 'is located at a distance from the vertical plane defined by the vertical face 33', towards the second side of the slide 32 '.

Le fonctionnement est similaire à celui précédemment décrit.The operation is similar to that previously described.

Toutefois, si les parois latérales 5, 6 sont toujours en contact avec les côtés de la glissière 32' (respectivement face verticale 33' et sommet 37'), les dents 15 sont dans ce cas en contact avec les parois supérieure 35' et inférieure 36' du creux central 34' au niveau des zones d'angle arrondies 22. Ainsi, en position montée, chaque aile 12 s'étend sensiblement verticalement, et la dent 15 de chaque aile 12 est en contact et en appui contre la glissière 32', du côté opposé à la première paroi latérale 5.However, if the side walls 5, 6 are still in contact with the sides of the slide 32 '(respectively vertical face 33' and top 37 '), the teeth 15 are in this case in contact with the upper walls 35' and lower 36 'of the central hollow 34' at the rounded corner areas 22. Thus, in the mounted position, each wing 12 extends substantially vertically, and the tooth 15 of each wing 12 is in contact and bears against the slideway 32 ', on the opposite side to the first lateral wall 5.

Par ailleurs, les crochets 31 coopèrent avec le rebord supérieur 38' de la glissière 32', ce qui permet d'éviter le basculement du dispositif 1 du fait que la première paroi latérale 5 n'est pas en contact avec ce rebord 38'.Furthermore, the hooks 31 cooperate with the upper rim 38 'of the slide 32', which prevents the tilting of the device 1 because the first side wall 5 is not in contact with the flange 38 '.

Ainsi, l'invention apporte une amélioration déterminante à la technique antérieure, en fournissant un dispositif de support de maniement simple, ne nécessitant pas d'outil ni une force particulière, et dont le verrouillage et le déverrouillage sont intuitifs. Parmi les autres avantages du dispositif de support selon l'invention, on peut citer :

  • le fait qu'il s'adapte aux deux types classiques de glissières métalliques notamment grâce à la géométrie particulière des dents ;
  • le dispositif de support est facile à transporter grâce à la poignée servant également de moyen d'actionnement du pivotement du bras ; le dispositif de support se fixe efficacement sur la glissière sans que cela nuise à la facilité de retrait ultérieur ;
  • la masse du dispositif est bien inférieure à celle des dispositifs connus (dans la réalisation représentée, le dispositif pèse environ 7 kg).
Thus, the invention provides a decisive improvement to the prior art, providing a support device for simple handling, requiring no tools or special force, and whose locking and unlocking are intuitive. Among the other advantages of the support device according to the invention, mention may be made of:
  • the fact that it adapts to the two conventional types of metal rails, particularly thanks to the particular geometry of the teeth;
  • the support device is easy to transport thanks to the handle also serving as means for actuating the pivoting of the arm; the support device is effectively fixed to the slideway without affecting the ease of subsequent removal;
  • the mass of the device is much lower than that of known devices (in the embodiment shown, the device weighs about 7 kg).

Il va de soi que l'invention n'est pas limitée aux modes de réalisation décrits ci-dessus à titre d'exemples mais qu'elle en embrasse au contraire toutes les variantes de réalisation.It goes without saying that the invention is not limited to the embodiments described above as examples but that it encompasses all variants.
