Description

ROAD TRAFFIC SIGNALING SYSTEM

TECHNICAL DOMAIN E TO WHICH THE INVENTION REFERS

The present invention relates generally to the field of road signs. It relates more particularly to a road sign system on a road vehicle. It is more particularly intended for the neutralization by way of marking of traffic lanes with a lane changeover requirement for vehicles traveling by Lightning Arrow (FLR).

ARRI TECHNOLOGICAL BACKGROUND E

Road traffic signaling systems are known, in particular on a road vehicle and / or by luminous display, by the documents FR2729979, FR2972734, FR3012155, FR2883892, EP1837444, FR2706923, FR2671895, WO200724179, EP-570284 and US3622980.

The following documents are also known:

- DE 20 2016 106258 U1 which describes a system for limited height warning with a high panel which can be pivoted laterally around a joint in order to be able to overflow laterally,

WO 2007/024179 A1, which describes a panel system with a top-tilting light display and a part of which can translate laterally (the arms 6a and 6b), and

- FR 3,012,155 A1 which describes a high-panel light system with tilting light display, surmounting a low panel, all of the two panels can translate laterally.

The main use case of a lane change requirement is lane assignment at scheduled sites. The road vehicle carrying the prescription is located in full lane for the purpose of signaling. There is therefore a significant risk of collision by approaching vehicles at the rear of the vehicle. In order to reduce the risks and consequences of collisions, it has been proposed to shift the signaling assembly laterally relative to the chassis of the vehicle so that the majority of the shocks are experienced by the signaling assembly rather than by the vehicle itself. -even. However, there is no solution to avoid or further reduce collisions in certain identified cases and in particular in the case of passenger vehicles, which are generally the most numerous to circulate compared to van-type utility vehicles. or truck.

More specifically, the only movable part in lateral translation of the display assembly is its upper part which is light, which is lightweight in structure, and which can therefore protrude laterally from the general gauge of the trailer or the vehicle carrying the assembly. display. Consequently, there can be a lateral overflow of the general gauge of the trailer or the vehicle only above a height determined with respect to the roadway, this determined height being greater than the height of the passenger vehicles so that they can pass under the mobile part of the display unit in case they have not deviated sufficiently according to the prescriptions given by the signaling system.

Device

The invention therefore relates to a road and highway signaling system towed or on board vehicles. The terms front and rear are defined with respect to the direction of traffic of the vehicles to be deviated: they arrive from the rear of the signaling system and the signals that the system comprises must therefore be seen from the rear of the system.

Figures 1 to 10, there is shown by way of example a system 1 of road signs on a road vehicle which is a trailer 7 and to simplify the description its implementation to divert vehicles to the left. However, it is understood that the invention can be applied to other types of gear and that thanks to the possibilities of rotation of the B21 panel a1 or B21 a2 and displacement of one side side or the other of the high luminous arrow that the system includes, it is also possible to indicate a deviation to the right.

In Figure 1, the system 1 is in the configuration of displacement / transport and can be seen from the rear of the system, from the bottom up, the support structure which is a trailer 7, a lower section 2 of a first set display comprising information panels consisting of standard road signs and a first portion 6 of a second display assembly which is bright. The lower section 2 is substantially vertical and in a fixed position on the width of the trailer 7: it remains in the gauge of the width of the trailer 7. The first part 6 is fixed and arranged upwards of the lower section 2 of the set of panels and parallel to the upper edge of said section Like the lower section 2, this first part 6 remains in the width gauge of the trailer 7. The first part 6 here comprises eight light points of the type of individual luminous projectors 61 aligned horizontally, the upper edge of the lower section 2 itself being horizontal.

The lower section 2 comprises identification panels including a panel 24 of type B21 a1 or B21 a2 or its equivalent disposed in the median position and which is bordered at the bottom by a lower marking signal 22 and laterally by two lateral marking signals 21, 23 with typical red and white retroreflective taper strips B21 panel a1 or B21 a2 can be rotated to point to one side of the signaling system and this rotation can be manual (as in this example) or motorized .

This configuration of displacement / transport allows relatively high circulation speeds due to low air intake. This move / transport configuration also corresponds to a non-functional storage / storage configuration of the system.

In Figure 2, the system 1 is in pre-installation configuration on site: the trailer is at low speed and is about to stop or even is already stopped and the upper section 3 of the first set The display was unfolded upwards to position itself above the lower section 2. In fact, this upper section 3 which was in the folded position forward and not visible in FIG. 1 because hidden by the lower section 2 is here, in Figure 2, moved to the unfolded position.

The upper section 3, in this unfolded position, is substantially vertical. The upper section, both in folded and unfolded position remains fixed transversely: it remains in the gauge of the width of the trailer 7. The upper section 3 comprises signs including an upper beacon signal 32 and laterally two lateral marking signals 31, 33.

The upper section 3 carries towards the rear of the system (observer side in FIGS. 2 to 8) a second portion 5 of the second display assembly which is illuminated. This second part 5 is mounted movable in lateral translation, on one lateral side or the other, on the high section 3. The first part 6 of the luminous display has been marked by dotted lines as this first part 6 is further forward than the horizontal low line of light spots of the second illuminated display part 5 and is masked by the latter, as can be better seen in the following figures, including the 9.

The upper section 3 in the unfolded position in FIGS. 2 to 9 is substantially vertical and in the plane of the lower section 2. The second part 5 comprises a set of luminous spots of the type of individual luminous projectors 52 fixed on a substantially rectangular perforated frame. consisting of profiles 53b, 53h, 54 assembled to form the upper (section 53h), lower (profile 53b) and lateral (profiles 54) sides of the frame as well as two inner intersecting diagonal sections 55. Each oblique profile joins at one of its ends the sections 53b, 54 of sides at the lower corner, right or left, of the frame. This arrangement of the profiles and the luminous projectors 52 makes it possible to create luminous arrows oriented either on one lateral side or on the other side of the system by lighting some of said luminous projectors 52. Two more powerful and / or flashing lights 51 are further installed at the two upper side corners of the frame of the second portion 5 of the second illuminated display assembly.

The light spots of the first part 6 and the second part 5 are typically projectors type KR1 200 mm in diameter. Those of the second part 5 allow, depending on the selection of those who are lit, to form a downward oblique light arrow, type KR43. The two lights 51 are of type KR2. These light points and lights 61, 51, 52 are controlled so that the light intensity is reduced during the night. For this purpose, a manual switch or automatic detection J / N is implemented.

It is understood that the set of identification panels consisting of the lower section 2 and the upper section 3 and which is fixed laterally and remains in the width gauge of the trailer 7 comprises two frames, one per section, each carrying the panels. corresponding signs. These two frames of the two sections 2, 3 are made of metal profiles. These two frames are hinged together along a horizontal transverse hinge axis and located at the lower horizontal edge of the upper section 3 and the upper horizontal edge of the lower section 2. The articulation corresponding to the axis horizontal transverse articulation is biocable and this blocking can for example be achieved by the installation of at least one nut + bolt through the openings of the frame profiles of the two sections 2, 3 hinged together or by any other means of locking for the unfolded position, the sections 2, 3 then being parallel to each other, and / or folded, the sections 2, 3 then being inclined to one another. In variants, the locking means may be disposed between the upper section 3 and a portion of the vehicle.

In Figures 3 to 7, the system is stopped and the means of stabilization and immobilization of the trailer 7 have been deployed. Initially, FIG. 3, the system was passed in an on-site installation configuration when, in particular, retractable feet 77 and a rolling front wheel 73 were lowered on the roadway whereas previously they had been reassembled. If the trailer has a wheel brake 72, the latter is also placed in the clamping position.

In these Figures 3 to 7 there is shown the lateral translation, here to the left, of the second portion 5 of the second light display assembly to move the system to the final functional configuration. This offset in lateral translation makes it possible to make the profiles constituting the frame of the second part 5 more visible in the figures and to realize that this second part is indeed a light structure having little grip on wind or air displacements caused by by the traffic of deviated vehicles.

It may be noted that in FIG. 3, the first luminous display portion 6 is still marked by dashed lines because the latter is obscured by the horizontal low line of light spots of the second illuminated display portion 5 which is further back (towards the observer). In the following figures 4 to 7, the first portion 6 of light display is progressively unmasked as the lateral offset of the second portion 5.

The lightning down arrow can be displayed by the second portion 5 of the second illuminated display assembly is therefore laterally shifted. This lateral displacement of the second portion 5 of the second light display assembly is provided by a conventional mechanical drive system motorized gear type, rack, guide rails and rollers. As an example of such a mechanical drive system can be referred to the patent application FR2972734. More generally, the system of the invention with a lateral offset of the luminous drawdown arrow can be embarked or towed.

FIG. 8 of the final functional configuration of the system makes it possible to better visualize the structures of the two main display assemblies, the first set of descriptive panels with its lower section 2 and its upper section 3 and the second set of illuminated displays with its first fixed part 6 and its second part 5 movable in lateral translation. In this figure 8 can be seen forwards (in the background in the figure) cross sections 34 of the frame of the upper section 3.

In FIG. 9, the exemplified system is in the final functional configuration and it can be seen that the raised section 3 which has been raised is substantially in the vertical continuity / in the plane of the lower section 2 with respect to the first set of panels. Safety. The lower section 2 is fixed downwards along the rear edge of a platform 71 of the trailer 7. The lower section 2 is also fixed and retained towards its upper edge by oblique amounts 75 extended from top to bottom and back to front. Preferably there is an oblique amount 75 on each lateral side of the trailer. The panel 24 of type B21 a1 or B21 a2 or its equivalent of the lower section 2 is, in this example, manually turned and a device 25 with gripping handle and locking / unlocking is visible in Figures 9 and 10 behind the section bass 2.

Figures 9 and 10, the first portion 6 of the second light display assembly is visible at the top of the lower section 2 on the rear of the latter. The upper section 3 is slidably rearwardly movable, the second part 5 of the second illuminated display assembly. The high section 3 and the second part

5 are and remain parallel to each other. It is clearly understood that the light spots 52 aligned horizontally along the lower leg 53b of the frame of the second part 5 are level with the light points 61 aligned horizontally towards the upper edge of the first part 6 and therefore that seen from the rear as in FIGS. 2 to 8, the light spots 61 of the first part

6 are masked partially or totally (according to the lateral offset of the second part 5) by those of the second part 5.

In Figure 10, the upper section 3 has been folded forward and is caused to rest on the oblique posts 75 and where it can be locked as a safety measure by a mechanical lock or magnetic or electromagnetic control.

The towing arm 74 is disposed at the front of the towed system 1 and a front wheel 73 which can be lowered allows taxiing during installation or during storage. The retractable feet 77 motorized here are in the lower position Figure 9, resting on the road, and in the high position Figure 10. The trailer exemplified is four-wheel 72, two on each side of the trailer 7. A compartment 76 is installed on platform 71 of the trailer

7 to house useful equipment such as a power supply and electronic and computer means including automation.

The operation of the system 1 can be completely manual or, then, partially or fully motorized with respect to the unfolding or folding of the upper section 3 and the lateral translation of the second part 5 for its offset or its return to the template width of the road vehicle and, possibly, for the retractable feet 77 and / or the front wheel 73. In addition, in case of motorization, the corresponding commands may be under the control of a road / operator agent or, then , be partly or fully automated and, in particular, automatic tripping (s) with slaving to the speed of the towing vehicle or carrier of the system. The system preferably comprises a computer / electronic control device for the operation of the system allowing in its most evolved version an extensive automatism. The system can also be remote controlled, by wire or radio, and possibly transmitted by wire or radio, data and / or information. Wired transmission may be possible for a system installed on the roof and rear of a vehicle since the system is then attached to the vehicle.

Thus, preferably, the unfolding of the upper section 3 occurs when the towing vehicle has a speed which passes below a first threshold and the offset / lateral translation of the second part 5 occurs when the towing vehicle has a speed which passes below a second threshold below the first speed threshold. It is understood that there is a device to allow / unblock or not / block this automation will unlock this automation on arrival at the site where the system must be installed and made operational. Similarly, in case of automation, the road officer has manual controls to take over the whole system or for part or all possible maneuvers including those of the high section 3 and the second part 5 The automation is preferably connected to sensors making it possible to know in particular the positions of the mobile elements of the system or other parameters useful for control, security or recording. Thus, the currents / intensities of the electric motors of the motorized elements can be measured to detect blockages or resistance to mobility and / or delays are implemented to stop commands or return to safety positions if an action does not occur. could not be executed within a predefined time. Similarly, shock detectors can be implemented.

As an example of automation and in accordance with the safety rules and the marking procedures, the automation analyzes the speed of the vehicle and starts the lateral offset operation of the second part 5 automatically, without operation of the road agent, as soon as the speed of the vehicle falls below a defined threshold. This threshold is preferably adjustable. For example, the automatic offset threshold of the second part 5 is set to 30km / h.

It is understood that before the luminous arrow displayed on the second part can be shifted laterally, it is necessary that the road officer has previously unfolded the upper section 3 either by a manual control, or by the automatic unlocked for this purpose by the road officer and in the latter case by detecting a speed less than or equal to 90km / h (but greater than the lateral offset threshold of the second part 5): the high section 3 then gets up and can start its signaling illuminated by remaining in the width gauge of the road vehicle. The towing or hauling vehicle decelerates up to 30km / h and the boom then drifts automatically to the appropriate side, in accordance with the active light signaling and with the orientation of the panel type B21 a1 or B21 a2. Note that for the latter, in the case where its rotation is manual, the road agent will have taken care to guide before leaving for the installation site.

Thanks to the system, the offset of the only Lightning Folding Arrow allows the road officer to position himself further away from the traffic of the traffic lane while condemning it as with a conventional lightening boom.

For example, if a user in Light Vehicle approaching the markup does not deviate sufficiently his trajectory in time, he could be brought to pass under the light arrow instead of striking the signaling device of the existing solutions.

To uninstall the system, either to move it to the site or to repatriate it to its home base, the previous steps are run backwards. To allow the displacement on site one can be satisfied to raise the retractable feet 77 or even the roulette before 73 if a towing is necessary. For repatriation, it is necessary to bring the second part 5 next to the upper section 3 and then fold this upper section 3. As previously these steps can be manual, semi-automatic or automatic.
