Description

DISPOSITIF A ELEMENT SIGNALETIQUE AUTORELEVANT DEVICE WITH SELF-LIFTING SIGNAL ELEMENT
La présente invention concerne un dispositif, notamment de signalisation de type autorelevant . On utilise souvent dans le domaine de la signalisation routière, afin de marquer des zones dangereuses, des dispositifs de signalisation qui sont constitués d'éléments coniques maintenus en position verticale par une embase plane. Ces dispositifs qui, par nature, se doivent d'être particulièrement légers, présentent l'inconvénient d'être facilement renversables notamment sous l'effet du vent, et restent ensuite en position renversée. Or on sait que de tels dispositifs, lorsqu'ils sont renversés, deviennent quasiment invisibles aux usagers, si bien qu'ils constituent alors un réel danger à l'égard des usagers de la route.The present invention relates to a device, in particular for signaling of the self-rising type. Often used in the field of road signs, to mark dangerous areas, signaling devices which consist of conical elements held in vertical position by a flat base. These devices, which by their nature must be particularly light, have the drawback of being easily reversible, in particular under the effect of the wind, and then remain in the inverted position. However, we know that such devices, when overturned, become almost invisible to users, so that they then constitute a real danger with regard to road users.
Une telle situation contraint les services de maintenance à effectuer de multiples interventions afin de les remettre en position verticale. La présente invention a pour but de proposer un dispositif, utilisable notamment dans le domaine de la signalisation, qui présente la particularité essentielle de se relever de lui-même.Such a situation forces maintenance services to carry out multiple interventions in order to return them to an upright position. The present invention aims to provide a device, used in particular in the field of signaling, which has the essential characteristic of getting up on its own.
La présente invention a ainsi pour objet un dispositif, notamment de signalisation, comportant une embase, et un élément signalétique solidaire de celle-ci, ce dispositif étant apte à occuper une position couchée instable et une position relevée stable, caractérisé en ce que : - la section droite axiale de l'embase forme quatre côtés, à savoir une petite base, apte à venir en contact avec le sol lorsque le dispositif est en position relevée, une grande base opposée à la petite base et parallèle à celle-ci, deux côtés latéraux symétriques par rapport à un axe perpendiculaire aux bases et qui forment une ligne convexe vue de l'extérieur,The present invention thus relates to a device, in particular for signaling, comprising a base, and a signaling element integral with the latter, this device being capable of occupying an unstable lying position and a stable raised position, characterized in that: - the axial cross section of the base forms four sides, namely a small base, capable of coming into contact with the ground when the device is in the raised position, a large base opposite to and parallel to the small base, two lateral sides symmetrical with respect to an axis perpendicular to the bases and which form a convex line seen from the outside,
- les formes et dimensions de l'embase et de l'élément signalétique sont telles que, lorsque le dispositif est couché sur le sol, son centre de gravité est situé du côté de la petite base par rapport à une ligne perpendiculaire au sol au point de contact de l'embase avec celui-ci.- the shapes and dimensions of the base and the descriptive element are such that, when the device is lying on the ground, its center of gravity is located on the side of the small base with respect to a line perpendicular to the ground at the point contact of the base with it.
Dans un mode de mise en oeuvre de l'invention la grande base et/ou la petite base de l'embase est de forme carrée, ou rectangulaire. Elle peut également être polygonale ou circulaire.In one embodiment of the invention, the large base and / or the small base of the base is square, or rectangular. It can also be polygonal or circular.
Préférentiellement l'embase est réalisée dans un matériau de plus forte densité que celle de l'élément signalétique. Par ailleurs la partie supérieure de l'embase peut être creusée de façon à former une cuvette . La présente invention est particulièrement intéressante en ce que malgré ses capacités de relevage il se trouve, en position normale d'utilisation, dans une position aussi stable que ceux de l'état antérieur de la technique . Le présent dispositif est également intéressant en ce que, comme les dispositifs de l'état antérieur de la technique, il est facilement empilable, ce qui facilite son transport et son stockage.Preferably, the base is made of a material of higher density than that of the sign. Furthermore, the upper part of the base can be hollowed out so as to form a bowl. The present invention is particularly advantageous in that, despite its lifting capacities, it is in the normal position of use, in a position as stable as those of the prior art. The present device is also advantageous in that, like the devices of the prior art, it is easily stackable, which facilitates its transport and storage.
Dans un mode de mise en oeuvre intéressant de l'invention, le dispositif peut être constitué en deux parties, à savoir une embase qui est en permanence en contact avec le sol et un élément signalétique, notamment constitué d'un cône, qui est apte à se fixer sur l'embase, par exemple par emboîtement à force. On décrira ci-après, à titre d'exemples non limitatifs, diverses formes d'exécution de la présente invention, en référence aux dessins annexés sur lesquels :In an advantageous embodiment of the invention, the device can be made up of two parts, namely a base which is permanently in contact with the ground and a sign, in particular consisting of a cone, which is capable of being fixed on the base, for example by force fitting. Various embodiments of the present invention will be described below, by way of non-limiting examples, with reference to the appended drawings in which:
La figure 1 est une vue en coupe axiale et verticale d'un dispositif de signalisation suivant l'invention en position renversée.Figure 1 is an axial and vertical sectional view of a signaling device according to the invention in the inverted position.
La figure 2 est une vue en coupe axiale et verticale du dispositif de signalisation représenté sur la figure 1 au cours de sa phase de redressement .Figure 2 is an axial and vertical sectional view of the signaling device shown in Figure 1 during its recovery phase.
La figure 3 est une vue partielle en coupe axiale et verticale du dispositif de signalisation représenté sur les figures 1 et 2 en position stable d'utilisation.Figure 3 is a partial view in axial and vertical section of the signaling device shown in Figures 1 and 2 in the stable position of use.
La figure 4 est une vue de dessus du dispositif de signalisation représenté sur les figures 1 à 3.FIG. 4 is a top view of the signaling device shown in FIGS. 1 to 3.
La figure 5 est une vue en coupe partielle axiale et verticale d'un dispositif de signalisation suivant l'invention réalisé en deux pièces solidarisées.Figure 5 is a partial axial and vertical sectional view of a signaling device according to the invention produced in two integral parts.
La figure 6 est une vue partielle en coupe axiale et verticale d'une variante d'un dispositif de signalisation suivant l'invention à couple de redressement amélioré. Le dispositif de signalisation représenté sur les figures 1 à 4 est essentiellement constitué d'une embase 1 et d'un élément signalétique constitué dans l'exemple représenté par un cône 3. Dans le présent mode de mise en oeuvre, l'embase 1 et le cône 3 sont constitués d'une même pièce en matière de synthèse obtenue par moulage. En vue de dessus, ainsi que représenté sur la figure 4, l'embase 1 a la forme d'un carré dont les angles sont arrondis . Cette embase pourrait bien entendu notamment être de forme circulaire ou rectangulaire. Le dispositif de signalisation présente un axe de symétrie yy' , et si on le représente en coupe par un plan passant par cet axe de symétrie yy' , ainsi que représenté notamment sur les figures 1 et 2, on constate que la section droite de l'embase 1 est constituée de quatre côtés, à savoir une petite base la, une grande base lb et deux côtés latéraux le qui sont symétriques par rapport à l'axe yy' . La petite base la du dispositif de signalisation est disposée à la partie inférieure de l'embase 1 de façon, qu'en position normale d'utilisation, le dispositif prenne appui sur celle-ci, ainsi que représenté, sur la figure 3 ce qui lui confère une bonne stabilité. Les extrémités de la grande base lb et de la petite base la sont réunies par les deux autres côtés le qui forment une courbe convexe lorsqu'on la regarde de 1 ' extérieur. Ainsi que représenté sur les figures, l'embase 1 est creusée de façon à former une cuvette 4 , ce qui permet de déplacer son centre de gravité G en direction de la petite base la. Les dimensions de l'élément signalétique 3, et notamment sa longueur, ainsi que la répartition du poids de l'embase 1 sont telles que, lorsque le dispositif de signalisation est en position couchée, ainsi que représenté sur la figure 1, et qu'il est ainsi en contact avec le sol d'une part par son élément de signalisation 3 et par l'angle supérieur de l'embase 1, le centre le gravité G de l'ensemble soit situé du côté de la petite base la par rapport à une droite zz' perpendiculaire au sol au point de contact 0 de l'embase 1 avec celui-ci.Figure 6 is a partial view in axial and vertical section of a variant of a signaling device according to the invention with improved righting torque. The signaling device represented in FIGS. 1 to 4 essentially consists of a base 1 and of a descriptive element constituted in the example represented by a cone 3. In the present embodiment, the base 1 and the cone 3 are made of a single piece of synthetic material obtained by molding. In top view, as shown in Figure 4, the base 1 has the shape of a square whose corners are rounded. This base could of course in particular be of circular or rectangular shape. The signaling device has an axis of symmetry yy ', and if it is represented in section by a plane passing through this axis of symmetry yy', as shown in particular in Figures 1 and 2, we see that the cross section of the 'base 1 is made up of four sides, namely a small base la, a large base lb and two lateral sides le which are symmetrical with respect to the axis yy'. The small base 1a of the signaling device is arranged at the lower part of the base 1 so that, in the normal position of use, the device is supported thereon, as shown in FIG. 3 which gives it good stability. The ends of the large base 1b and the small base 1a are joined by the two other sides 1c which form a convex curve when viewed from the outside. As shown in the figures, the base 1 is hollowed out so as to form a bowl 4, which makes it possible to move its center of gravity G in the direction of the small base 1a. The dimensions of the descriptive element 3, and in particular its length, as well as the distribution of the weight of the base 1 are such that, when the signaling device is in the lying position, as shown in FIG. 1, and that it is thus in contact with the ground on the one hand by its signaling element 3 and by the upper angle of the base 1, the center the gravity G of the assembly is located on the side of the small base by with respect to a straight line zz 'perpendicular to the ground at the point of contact 0 of the base 1 with it.
On constate ainsi, dans ces conditions, que le centre de gravité G, lorsque le dispositif de signalisation est couché, crée un couple de redressement C ayant pour effet de faire pivoter le dispositif sur le côté le pour 1 ' amener tout d'abord dans une position intermédiaire, ainsi que représenté figure 2, puis en position stable, ainsi que représenté sur la figure 3 puisqu'il prend alors appui sur la petite base plane la.It is thus found, under these conditions, that the center of gravity G, when the signaling device is lying, creates a righting torque C having the effect of pivoting the device on the side to bring it first in an intermediate position, as shown in Figure 2, then in a stable position, as shown in Figure 3 since it then rests on the small flat base.
Le dispositif de signalisation suivant 1 ' invention est ainsi un dispositif redressable qui, après avoir été couché sous l'effet d'un choc, du vent, etc... reprend de lui-même une position stable . Bien entendu, afin d'améliorer la valeur du couple de redressement C on peut disposer à la partie inférieure de l'embase 1 des moyens de lestage, qui peuvent être constitués notamment par une rondelle métallique 6 fixée par collage dans celle-ci, ainsi que représenté sur la figure 6 , ou encore par des billes métalliques .The signaling device according to the invention is thus a rectifiable device which, after having been laid down under the effect of a shock, wind, etc., resumes itself a stable position. Of course, in order to improve the value of the righting torque C, it is possible to have ballasting means at the lower part of the base 1, which can be constituted in particular by a metal washer 6 fixed by bonding therein, thus as shown in Figure 6, or by metal balls.
Bien entendu l'élément signalétique qui, dans les exemples décrits, est constitué d'un cône 3, peut être formé de tout autre élément, fonction de l'utilisation que 1 ' on souhaite en faire . Ainsi que représenté sur la figure 5 le dispositif de signalisation peut être réalisé en deux parties, qui peuvent être faites de matériaux différents, et notamment de matériaux de densités différentes . On prendra ainsi un matériau beaucoup plus dense pour réaliser l'embase 1, ce qui aura pour effet d'améliorer le couple de redressement C du dispositif.Of course, the descriptive element which, in the examples described, consists of a cone 3, can be formed of any other element, depending on the use which one wishes to make of it. As shown in Figure 5 the signaling device can be made in two parts, which can be made of different materials, and in particular of materials of different densities. This will take a much denser material to make the base 1, which will have the effect of improving the righting torque C of the device.
Dans l'exemple représenté sur la figure 5 la partie inférieure de 1 ' embase 1 comporte un orifice tronconique 7 de même conicité que celle de l'élément signalétique 3, si bien que ces deux éléments peuvent se fixer par exemple par coincement, avec adjonction ou non de moyens de collage.In the example shown in Figure 5 the lower part of 1 base 1 has a frustoconical orifice 7 of the same conicity as that of the sign 3, so that these two elements can be fixed for example by wedging, with addition or not of bonding means.
Un avantage du dispositif de signalisation suivant l'invention est qu'il est empilable ce qui est intéressant du point de vue du stockage et du transport. An advantage of the signaling device according to the invention is that it is stackable, which is advantageous from the point of view of storage and transport.
