Definitions

• Mobile device for signaling the occupation of a road lane and diverting traffic.
• the present invention relates to the road sector and more particularly to a separate roadway and has as its object a mobile signaling device to inform road users as far upstream as possible of the occupation of a lane and to divert traffic.
• the device according to the invention overcomes these drawbacks.
• it is preferably mounted as a kit on a vehicle of 2 to 5 tonnes of total weight laden, or even on a trailer, and makes it possible to signal the neutralization of a lane on a road with separate carriageways and to be brought the user i gradually slow down first and then deviate.
• the device comprises a motorized arm, articulated at one of its ends provided at the other end with a preferentially parabolic reflector equipped with a preferentially halogen light source, capped with an external cover delimiting preferably a boom, the assembly can be seen at a distance of the order of a kilometer, the arm in operation is permanently animated by an alternating rotation movement oriented either on the right side to deviate to the right, or on the left side to deviate to the left, at the same time time the light source is lit, either continuously or discontinuously, during the descent of the arm, preferably with progressive switching on and off.
• a motorized arm articulated at one of its ends provided at the other end with a preferentially parabolic reflector equipped with a preferentially halogen light source, capped with an external cover delimiting preferably a boom, the assembly can be seen at a distance of the order of a kilometer, the arm in operation is permanently animated by an alternating rotation movement oriented either on the right side to deviate to the right,
• - continuous or even discontinuous ignition is an information message that is both strong and quiet, immediately understandable by users, who then manage their stress much better.
• the vehicle can be equipped at the rear with one or more fixed or removable shock absorbers, possibly 3 one or more being liftable so, after recovery, & occupy a reduced space in the garage and during transport, to constitute a mask of the signaling system and to trivialize the vehicle.
• the attenuators can be placed one above the other, the one above recessed from the one below, so that the lower mitigates the shocks of light vehicles, the higher and lower reduce the impact of heavy vehicles.
• the device makes it possible to divert the traffic on either side of the carrier vehicle by creating the alternative oscillation of travel adjustable on either side of the vertical plane passing through the axis of rotation of the arm.
• the arm and its reflector can move by construction - on the one hand laterally outside the vehicle gauge generally limited to 2.50 meters and until occupying at least the entire width of the track generally limited & 3.50 meters which allows the mounting of an arm distance between axis and end of the order of 2.25 meters.
• the axis of rotation of the arm can be mounted on a mobile column, for example telescopic, secured to the chassis and / or possibly translatable for example laterally.
• the arm can be equipped with one or more forearms, which allows, by combination of movements, all types of positioning and displacement, for example a vertical alternating movement above the lateral track.
• an obstacle presence sensor for example with ultrasound or infrared, preferably installed at the end of the arm, makes it possible to detect, for example, the apron of an overpass, or an electric wire and to automatically trigger the removal of the column or arm to bring these elements inside the available templates while ensuring beyond these delicate passages the automatic or manual return to the initial positions.
• the arm can be split symmetrically, balanced, the two arms are then integral, driven in a rotational movement which can be
• the plane formed by the arm (s) which is perpendicular to the axis of the vehicle can be oriented around a vertical axis, for example the axis of the column so as to partially correct the parallax defect between the axis of the light source and the axis of vision of road users, in particular in the case of an installation at a bend in the road.
• This orientation can be carried out manually or automatically by a mechanical link connected to a connecting rod of the vehicle steering or any other system chosen by analogy with the servo systems used on vehicles with four steered, mechanical, electric, electronic wheels.
• the visibility of the arrow can be reinforced by the presence of a visor, this visor can be rotatable, for example around the free edge of the bowl containing the reflector for example by means of a ball crown and the position of the visor can be controlled by means of pinions or belt and teeth on the crown or by means of a parallelogram to a base fixed at the level of the axis of the arm so as to maintain the same orientation of the visor whatever the position of the arm. Another way is to simply ballast the visor at its opposite low point.
• the device to be regulatory may include one or more type B 21 panels, preferably placed on the low attenuator so as to retract them with the raising of the attenuators, thus trivializing the vehicle.
• the adapted optics on the reflector can be flat, it can also be constituted by a Fresnel lens so as to improve identification by users.
• the light source can be composed of several sources, in particular a flash source which will preferably be triggered automatically only when the Visibility is doubtful, all the sources being able to be synchronized using a automaton whose incrementation can be made by sensor or by a cam sector mounted on the axis of the arm making automatic synchronization while remaining adjustable by the displacement of the sensors whatever the stroke chosen for the beating of the arms.
• Side rails surround the vehicle.
• the arm can be equipped with projectors synchronized with the lighting of the light source so as to reinforce the arrow effect.
• Figure 1 shows, seen by the user, the device according to the invention.
• Figure 2 shows, laterally this device.
• the device shown in Figures 1 and 2 comprises a vehicle (1) equipped with a support (2) located behind the cabin provided in its upper part with a substantially horizontal axis (3) on which is articulated an arm (4 ) carrying at its end a bowl (5) of the order of 0.80 m in diameter, preferably hemispherical, ovoid and / or cylindrical in shape provided with a reflector (6), one or more light sources (7 ), an optic (8), a cover (9).
• the length between the axis of the arm and its end on the bowl is of the order of 1.25 m up to 2.25 m and more.
• a not shown gearmotor or a not shown actuator drives the arm in one direction or the other via a controller and synchronization, for example by cam and rotary contacts.
• a jack (14) not shown housed horizontally in the axis of the chase ensures the simultaneous lifting by the tie rod (15) of the high attenuator secured to that of the arm by belts and lateral arms (16) articulated, consisting of simple plates so as not to transmit stress without shock.
• a boom of 1.50 meters which can for example be composed of 7 lamps of 35 W of 50 centimeters in diameter with 300 mm of unit length, that is 245 watts or 30,000 lumens, visible from more than one kilometer distance.
• the ignition of sodium lamps is long on the order of 10 minutes, this is not a drawback because this period remains less often than travel time. Switching off for one to a few seconds and instant re-ignition are possible by the following assembly from a 12 or 24 volt DC battery by combining:
• a manual or automatic intensity reduction device coupled to a brightness measurement cell.
• the battery can be replaced by an alternating current generator eliminating the inverter.
• a single new light source preferably can be mounted on a new independent telescopic column placing the above source very high above the vehicle to signal it.
• low pressure sodium lamps can be used to signal places, for example construction site, accident zone, black dot, ...
• This signaling could be fixed or animated, being able to represent symbols or simply suffice with its illuminating tube, in particular positioned vertically, asserting its singularity and offering low wind resistance.
