Description

Technical field of the invention

The invention relates to an advertising display module for a road safety barrier bordering a traffic axis. The invention applies particularly to road safety barriers bordering automobile circuits, in particular urban automobile circuits.

Technology background

It is common for road traffic lanes, in particular those intended to form at least part of an urban circuit of a motor race, to be equipped with safety barriers intended to prevent vehicles from leaving the traffic lane in the event of an accident. 'accident.

Such a safety barrier is typically formed of one or more superimposed metal profiles each comprising at least one central groove and two lateral ribs separated by said central groove and each extending towards the road lane bordered by this barrier. This specific shape of the safety barrier makes it possible, in the event of an accident, to absorb the energy of the impact of the vehicle against the barrier by deformation of the lateral ribs. Such a slide therefore has an inverted W shape, the points of the W forming the tops of the ribs, and the space between points forming the central groove.

In the case of motor races using such a lane, it is known to place advertising panels or tarpaulins on the safety barriers to promote the commercial partners of the sporting event.

These advertising panels or tarpaulins are generally glued to the slides or fixed with straps or any equivalent means. FR2451606 discloses in particular an advertising display module for a road safety barrier according to the preamble of claim 1.

In practice, the operations of fixing advertising panels or tarpaulins to guardrails are long and fairly complex operations for the panels or tarpaulins to be properly fixed on the guardrails due to the specific shape of the guardrail mentioned below. above. These fixing operations are more restrictive for safety rails made up of several slides superimposed on each other and intended to accommodate large display panels.

In practice, these fixing operations require glues, straps, ground anchors (in the case of advertising tarpaulins), screwdrivers, bolting elements, etc.

In particular, in the case of an advertising tarpaulin mounted on a safety barrier, it should be tightened well so that it does not float between the ribs in order, on the one hand, to be visible to spectators or viewers and to on the other hand not to present a risk for car drivers (risk of the advertising tarpaulin detaching from the slide which could then hinder good visibility of the traffic lane).

The inventor therefore sought to develop an advertising display module which resolves at least some of the drawbacks of the solutions currently used for fixing advertising panels on road safety barriers and in particular, but not exclusively, those bordering the traffic lanes of urban automobile circuits.

Objectives of the invention

The invention aims to provide an advertising display module for a road safety barrier.

The invention aims in particular to provide, in at least one embodiment of the invention, an advertising display module for a road safety barrier bordering a traffic lane of an urban automobile circuit.

The invention also aims to provide, in at least one embodiment of the invention, such a module which can be mounted on a safety barrier without tools.

The invention also aims to provide, in at least one embodiment of the invention, such a module which can be reused to equip other safety barriers, without particular difficulties.

The invention also aims to provide, in at least one embodiment of the invention, such a module which helps to reinforce the safety of pilots in the event of impacts on the safety barrier equipped with such a module.

Presentation of the invention

• une garniture de remplissage longitudinale de section transversale sensiblement trapézoïdale, configurée pour pouvoir être logée dans ladite rainure centrale de ladite glissière de sécurité et présentant une première base en regard du fond de la rainure centrale, une fois la garniture logée dans ladite rainure centrale, et une deuxième base opposée s'étendant entre les sommets desdites nervures,
• des noyaux creux longitudinaux formés dans la garniture de remplissage au voisinage des extrémités latérales desdites bases de ladite garniture de remplissage,
• des aimants logés dans lesdits noyaux creux longitudinaux de manière à permettre le maintien par aimantation de ladite garniture de remplissage dans ladite rainure centrale de ladite glissière de sécurité,
• une surface plane de réception d'un affichage publicitaire formée par ladite deuxième base de ladite garniture qui s'étend sensiblement entre les sommets desdites nervures de ladite glissière lorsque ladite garniture de remplissage est logée dans ladite rainure centrale.

To do this, the invention relates to an advertising display module for a road safety barrier formed of a metal profile extending along a longitudinal direction and comprising at least one central groove and two lateral ribs each extending projecting from a vertical plane tangent to the bottom of the central groove in the direction of the roadway bordered by this slide, said display module being characterized in that it comprises:

• a longitudinal filling lining of substantially trapezoidal cross section, configured to be able to be housed in said central groove of said safety barrier and having a first base facing the bottom of the central groove, once the lining housed in said central groove, and a second opposite base extending between the vertices of said ribs,
• longitudinal hollow cores formed in the filling liner near the lateral ends of said bases of said filling liner,
• magnets housed in said longitudinal hollow cores so as to allow said filling lining to be maintained by magnetization in said central groove of said safety barrier,
• a flat surface for receiving an advertising display formed by said second base of said lining which extends substantially between the tops of said ribs of said slide when said filling lining is housed in said central groove.

The advertising display module therefore has the advantage of being able to be housed in the central groove of the metal profile of a road safety barrier and to extend up to the level of the ribs of the barrier.

In particular, the display module comprises a longitudinal filling insert of substantially trapezoidal cross section, which makes it possible to accommodate the insert in the central groove by conforming to the shape of the slide.

By definition, a trapezoid is a convex quadrilateral which has two parallel opposite sides designated by the base terms.

In the case of the filling pad, the first base, also referred to as the “inner base”, is arranged facing the bottom of the central groove, once the module is housed in the slide, and the second opposite base, also designated by the terms “display base” or “external base”, extends between the tops of the ribs of the slide and forms a flat surface for receiving an advertising display. This flat surface extends substantially between the tops of the ribs so that the plane of this flat display surface merges substantially with the plane which passes through the two tops of the ribs. In other words, the filling trim of a module according to the invention makes it possible to fill the void between the two tops of the ribs of the slide.

The display module according to the invention therefore makes it possible to form a plane support for receiving an advertising display. This advertising display can be reported on the display basis by collage, by adhesive, or by any equivalent means.

Furthermore, the module is configured to be able to be held fixedly in the central groove via magnets housed in longitudinal hollow cores formed in the filling liner. Such a module can therefore be fixed in the slide without tools and without particular difficulty by an operator.

The magnets being housed in the filling lining, they ensure magnetization through the thickness of the filling lining.

Housing the magnets in the filling trim prevents direct contact between the magnets and a vehicle in the event of an accident. In other words, the magnets are embedded in the trim, which limits any risk of direct contact between the magnets and the vehicles in the event of an accident.

In addition, housing the magnets in the cores of the filling liner protects them against climatic conditions, and in particular rain, which prevents the appearance of corrosion.

Advantageously and according to the invention, each longitudinal hollow core receives a plurality of magnets regularly distributed inside the hollow core and spaced from one another by a spacer to prevent any movement of the magnets inside the cores.

In addition, this alternative embodiment makes it possible to form modules of great length, for example 3 meters, by providing for housing a plurality of magnets inside each core regularly distributed over the entire length of the core.

For example, for a 3 meter module, it can be planned to use 30 magnets of 4 cm each separated from each other by spacers (for example in PVC) of 6 cm each.

Of course, other distributions of magnets can be provided inside the longitudinal hollow cores without this calling into question the effect of the invention.

Another advantage of this alternative embodiment is to allow the modules to be mounted in slides bordering the bending zones while guaranteeing good magnetization of the module over the entire curvature of the bend.

According to other embodiment variants, the magnets can nevertheless extend longitudinally on either side of the hollow cores of the filling liner.

According to an advantageous variant, the magnets are neodymium magnets.

Of course, nothing prevents the use of other types of magnets to ensure the magnetization of the module in the guardrail.

Preferably, the module comprises four longitudinal hollow cores housed respectively near the lateral ends of the interior and display bases of the trim.

Advantageously and according to the invention, said filling trim further comprises at least one longitudinal recess whose cross section is shaped to at least one bolting element of said slide.

According to this variant, the module can be fixed on a slide having bolting elements such as screwing bolts of the slide on a post for fixing the slide or bolts connecting the slide to a slide adjacent. The recess being longitudinal, the installation of the module in the slide can be done without any particular precautions. In fact, each bolt will be housed in the recess of the corresponding trim, whatever the longitudinal position of the bolt relative to the module housed in the central groove of the slide.

In practice, a slide comprises at least one bolt, called a base bolt, intended to allow the fixing of the slide on a foot intended to carry the slide above the ground. This bolt is generally housed in the central groove of the slide. In practice, a slide also includes at each of its longitudinal ends, at least two bolts, called connecting bolts, intended to connect the slide to an adjacent slide. These bolts are generally arranged on the inclined walls connecting the central slide to each of the two adjacent ribs.

Advantageously and according to this variant, the module comprises at least three longitudinal recesses arranged respectively in the first base and on each of the two side walls of said filling insert connecting said bases in pairs.

This advantageous variant allows the module to be mounted at the level of the slide presenting the base bolts and the connecting bolts.

This advantageous variant makes it possible to fix the module on a slide having bolts, not only at the bottom of the central groove, but also on each of the side walls connecting the bottom of the groove and the tops of the ribs of the slide.

Advantageously and according to this variant, said longitudinal hollow cores are arranged on either side of the longitudinal recesses so that said magnets housed in said hollow cores can hold the lining on either side of the longitudinal recesses by magnetization.

This variant makes it possible to press the filling trim against the safety barrier on either side of the longitudinal recesses for passing the slide fixing bolts onto a fixing post.

Advantageously and according to this variant, each recess is delimited by a flexible wall adapted to be able to be stretched on either side of the elements of safety barrier bolting to adapt the magnetization zone defined by the position of the hollow cores.

This variant makes it possible to slightly stretch the flexible walls on either side of the bolting elements present in the guardrail to ensure the magnetization of the magnets on the guardrail.

Each wall can for example have a plurality of hinges in the wall, which gives it the flexibility and elasticity necessary to surround the bolting elements of the slide depending on their size.

Advantageously and according to the invention, said filling trim further comprises at least one side wing configured to be able to extend beyond the top of a rib of the slide, when said module is housed in said central groove of the slide , so as to make it possible to fill a space between the slides of a safety rail formed by at least two superimposed slides.

This advantageous variant is particularly intended for safety rails formed from a stack of safety barriers. Indeed, in the context of a stack of crash barriers (this is typically a stack of 3 or 4 crash barriers for Formula 1 type motor racing), an inter-railway space is naturally present between safety barriers. This space is delimited by the upper edge of the upper rib of the lower slide and by the lower edge of the lower rib of the upper slide.

The side wing of the module filling trim according to this variant which extends beyond the top of the rib (upper or lower depending on the orientation of the side wing) therefore makes it possible to fill this inter-slide space.

It is thus possible to form a large flat advertising display surface.

Also note that the module according to the invention could be modified to be able to be housed directly in the inter-slide space. In this case, the interior base of the module would no longer be intended to be housed in the central groove of the slide, but in the space between the slides. The overall structure of the module would be substantially identical, but the dimensions would have to be adapted to this inter-slide space.

Advantageously and according to the invention, said filling liner is made of elastomer.

This advantageous variant makes it possible to give the display module shock absorption properties which thus contributes to improving the safety of pilots in the event of an accident against the guardrails equipped with the display modules according to this variant.

Advantageously and according to the invention, the module further comprises light means, of the electroluminescent diode type, arranged on said flat surface for receiving an advertising display.

According to this advantageous variant, the display module comprises light means housed at the level of the display surface, for example on the periphery of the display surface to highlight the message on the display. These light means are for example light-emitting diodes (better known by the acronym LED) powered by batteries housed in the filling lining or any other known means.

The invention also relates to a road safety barrier formed of a metal profile extending along a longitudinal direction and comprising at least one central groove and two lateral ribs each extending projecting from a vertical plane tangent to the bottom of the groove towards the road lane bordered by this slide, characterized in that it further comprises at least one display module according to the invention housed in said central groove.

The advantages and technical effects of the display module according to the invention apply mutatis mutandis to the road safety barrier according to the invention.

Advantageously and according to the invention, the road safety barrier comprises a plurality of display modules housed longitudinally end to end in said central groove.

This advantageous variant makes it possible to produce a display on a long portion of the safety barrier.

Furthermore, the display modules according to the invention preferably have a length of between 0.5 m and 3 m so that it is possible to mount the modules in slides bordering the turning zones, the size of each module making it possible to follow the shape of the bend by placing the modules end to end. Furthermore, for elastomer modules, it is easy to deform the module longitudinally due to the elasticity of the material which constitutes them.

However, nothing prevents the provision of shorter or longer modules depending on the needs and the shape of the circuit to be equipped.

The invention also relates to a display module and a safety barrier, characterized in combination by all or part of the characteristics mentioned above or below.

Detailed description of an embodiment of the invention

In the figures, scales and proportions are not strictly respected for purposes of illustration and clarity. Throughout the detailed description which follows with reference to the figures, unless otherwise indicated, each element of the display module is described as it is arranged when the display module is mounted on a road safety barrier. This arrangement is represented in particular by the Figure 3 .

Furthermore, throughout the detailed description, the longitudinal direction corresponds to the main direction of the display module which coincides with the main direction of the road safety barrier intended to receive this display module. The vertical direction corresponds to the gravity of the location of the slide intended to receive the display module and the transverse direction corresponds to the direction perpendicular to the longitudinal and vertical directions.

The longitudinal, vertical and transverse directions are represented schematically by the trihedron L, V, T in the different figures.

In addition, identical, similar or analogous elements are designated by the same references in all the figures.

There figure 1 illustrates an advertising display module 10 intended to be mounted on a road safety barrier 40 formed of a metal profile which extends along the longitudinal direction L.

This slide shown in section on the Figure 5 comprises at least one central groove 41 and two lateral ribs 42, 43 which each extend projecting from a vertical plane P tangent to the bottom of the central groove 41 in the direction of the road lane bordered by this slide.

In general, the lateral ribs 42, 43 are identical so that the plane S which connects the top of the ribs 42, 43 is parallel to the plane P.

The display module comprises a longitudinal filling liner 11 which has a substantially trapezoidal cross section.

This trapezoidal section consists of a first base, called the interior base 12, which extends facing the bottom of the central groove 41, once the module housed in the slide, and an opposite parallel base, called the external base 13, which extends in the plane S between the vertices of the ribs 42, 43, once the module housed in the slide.

The trapezoidal section also has side walls 14, 15 which connect the interior 12 and exterior 13 bases in pairs.

As shown in the figures, the gasket 11 is preferably hollow so that the trapezoidal cross section corresponds to the periphery of the gasket.

The display module also includes longitudinal hollow cores 16, 17, 18, 19 formed in the filling lining in the vicinity of the lateral ends of the interior 12 and exterior 13 bases.

These cores 16, 17, 18, 19 house magnets 30, 31, 32, 33 intended to allow the display module to be fixed in the road safety barrier by magnetization.

A filling trim for a display module according to the invention is for example manufactured by elastomeric extrusion. Once the lining has been obtained, the magnets 30, 31, 32, 33 are inserted into the hollow cores 16, 17, 18, 19 of the lining.

According to an advantageous embodiment, the magnets 30, 31, 32, 33 are each formed of a plurality of individual magnets regularly distributed inside each hollow core and spaced from one another by a spacer , not shown in the figures, to prevent any movement of the magnets inside the core. In practice, we insert a first magnet into a hollow core, then we insert a spacer, for example made of PVC, then we insert a second magnet, then a spacer, and so on until each core is completely filled magnets and spacers.

In other words, in the figures, the references 30, 31, 33, 33 each represent a plurality of individual magnets housed in the respective hollow cores 16, 17, 18, 19.

However, according to other embodiments, nothing prevents the provision of magnets in one piece which each occupies all the space available in the hollow core receiving it.

Whatever the embodiment of the magnets, a display module according to the invention can be fixed without particular difficulty in the central groove 41 of a road safety barrier by magnetization.

The exterior base 13 of the lining forms, once the module housed in the slide, a flat surface for receiving an advertising display.

Thus and as represented schematically on the Figure 3 , an advertising display 48 can be stuck on the flat surface formed by the exterior base 13 of the trim, once the module is housed in the road safety barrier 40.

A module according to the invention is therefore particularly useful when road safety rails formed from the superposition of a plurality of road safety barriers are installed at the edge of a traffic lane.

Indeed, the arrangement of a plurality of modules in each slide makes it possible to form a large flat surface for receiving a large advertising display.

This therefore advantageously makes it possible to replace the tarpaulins used until now to cover road safety barriers during automobile competitions in particular.

The invention can also be used for the display of advertising messages in the vicinity of supermarkets or for the display of road safety instructions intended for motorists, for example to signal the occurrence of a dangerous bend or any other type of information.

According to a particular embodiment, the display module can further comprise light means housed at the level of the display surface, for example on the periphery of the display surface to highlight the message of the display . These light means are for example light-emitting diodes (better known by the acronym LED) powered by batteries housed in the filling lining or any other known means.

As shown in the figures, a display module according to a preferred embodiment further comprises longitudinal recesses 21, 22, 23 each having a cross section shaped like bolts 45 of the slide. These recesses are arranged respectively in the first base and on each of the two inclined side walls of said filling liner connecting two by two the bases of the filling liner 11.

According to this embodiment, the longitudinal hollow cores 16, 17, 18, 19 are arranged on either side of the longitudinal recesses 21, 22, 23 so that the magnets 30, 31, 32, 33 housed in the hollow cores 16, 17, 18, 19 can hold the lining 11 by magnetization on either side of the longitudinal recesses.

Each recess is delimited by a flexible wall so as to be able to adapt the magnetization zone defined by the position of the hollow cores according to the size of the bolting elements 45 of the safety barrier.

The flexibility of the wall is for example, and as shown in the figures, obtained by the presence of a plurality of hinges formed in the wall delimiting the recess. These hinges have the form of longitudinal notches which give flexibility to the wall due to the possibility of stretching the wall vertically (for the wall delimiting the recess 21), which thus allows the magnets to be well positioned on either side. and other bolting elements present in the slides.

According to a particular embodiment, a hinge of the wall formed at the level of the recess 21 can be complete, that is to say that the wall is cut at the level of this hinge. This makes it possible to separate the magnets 31, 32 from each other, without being limited by the wall delimiting the recess if necessary, and in particular if the bolting element to be covered by this wall presents a bulk important.

Of course, the shape and position of the recesses can be adapted, during the manufacture of the filling trim, to the shape, dimensions and positioning of the bolting elements of the safety barriers on which the module is intended to be fixed.

According to another embodiment not shown in the figures, the display module comprises a single recess 21 to accommodate the base bolt 45 of the slide. In this case, it is possible to predict only two lateral cores each extending substantially between the inner and outer bases and configured to receive each of the shaped magnets. This variant has the advantage compared to the embodiment of the figures of ensuring greater magnetization due to the size of the magnets housed in these two cores.

In practice, the filling of a slide can be carried out with modules according to the embodiment of the figures at the level of the slide comprising connecting bolts, that is to say in practice, in the vicinity of the longitudinal ends of the slide, and modules according to the embodiment with a single recess 21 elsewhere.

There figure 8 schematically illustrates three slides according to the invention superimposed on one another and each equipped with a plurality of display modules according to the invention.

There Figure 9 illustrates the same slides with a display panel stuck on the common flat surface formed by the plurality of display zones formed by the different display modules housed in the different slides.
