Description

TITRE : Feu de signalisation mobile de chantier TITLE: Mobile site signaling light
La présente invention concerne un feu de signalisation mobile de chantier. The present invention relates to a mobile site traffic light.
Les feux de signalisation mobiles de chantier permettent de réguler le trafic des véhicules sur des routes en travaux. Les feux sont apportés sur le chantier par un opérateur dans un véhicule utilitaire. Avec les feux actuels, la place disponible dans les véhicules une fois les feux chargés est très limitée du fait du volume occupé par les feux. D’autres part, lorsque ces feux ne sont pas utilisés, ils prennent une place importante dans les lieux de stockage. Mobile site traffic lights are used to regulate vehicle traffic on roads under construction. The fires are brought to the site by an operator in a utility vehicle. With the current lights, the space available in the vehicles once the lights are loaded is very limited due to the volume occupied by the lights. On the other hand, when these lights are not in use, they take up an important place in storage areas.
Il est connu de CN 110 503 842 A de proposer un feu de signalisation mobile comprenant un châssis et une tête de feu repliable entièrement dans le châssis lorsque le feu de signalisation n’est pas déployé. Cependant, un tel feu de signalisation mobile présente l’inconvénient d’utiliser un système élaboré pour déployer et replier la tête du feu, ce qui est inadapté à l’utilisation du feu de signalisation dans un environnement complexe, tel qu’un chantier. En outre, lorsque la tête de feu est descendue vers sa position repliée, son mouvement peut être très brusque, ce qui peut dès lors s’avérer dangereux. It is known from CN 110 503 842 A to provide a mobile traffic light comprising a frame and a folding light head entirely in the frame when the signal light is not deployed. However, such a mobile traffic light has the disadvantage of using an elaborate system for deploying and folding the head of the light, which is unsuitable for the use of the traffic light in a complex environment, such as a construction site. In addition, when the firehead is lowered to its stowed position, its movement can be very sudden, which can therefore be dangerous.
C’est à ces inconvénients qu’entend remédier l’invention en proposant un nouveau feu de signalisation mobile de chantier dont l’encombrement est réduit pour le transport et le stockage et dont le mécanisme de repli de la tête de feu est amélioré.. It is to these drawbacks that the invention intends to remedy by proposing a new mobile traffic light for construction sites, the size of which is reduced for transport and storage and the mechanism for retracting the head of the fire is improved.
A cet effet, l’invention concerne un feu de signalisation mobile de chantier, comprenant une tête de feu équipée d’un ou plusieurs signaux lumineux, et un châssis muni d’organes de liaison au sol. La tête de feu est mobile en rotation par rapport au châssis entre une position relevée et une position repliée et le châssis définit un volume de réception de la tête de feu en position repliée, dans laquelle la tête de feu ne dépasse pas du volume de réception du châssis. Selon l’invention, le feu de signalisation comprend des moyens de ralentissement de la rotation de la tête de feu entre sa position dépliée et sa position repliée. To this end, the invention relates to a mobile site signaling light, comprising a light head equipped with one or more light signals, and a frame provided with ground links. The fire head is movable in rotation relative to the frame between a raised position and a folded position and the frame defines a reception volume of the fire head in the folded position, in which the fire head does not protrude from the reception volume of the chassis. According to the invention, the traffic light comprises means for slowing down the rotation of the light head between its unfolded position and its folded position.
Grâce à l’invention, l’encombrement du feu lorsqu’il n’est pas en utilisation est réduit. Il est également possible d’empiler plusieurs feux et ainsi réduire l’emprise au sol. En outre, comme le mouvement de rotation de la tête de feu depuis sa position déployée vers sa position repliée est ralenti, les risques de blessure du personnel évoluant autour du feu de signalisation sont diminués. Thanks to the invention, the bulk of the light when not in use is reduced. It is also possible to stack several lights and thus reduce the footprint. In addition, as the rotational movement of the fire head from its deployed position to its folded position is slowed down, the risks of injury to personnel moving around the traffic light are reduced.

Les figures 1 à 7 représentent un feu de signalisation 1 mobile de chantier selon un premier mode de réalisation, comprenant une tête de feu 3 équipée d’un ou plusieurs signaux lumineux 5, et un châssis 7 muni d’organes de liaison au sol. Les organes de liaison au sol comprennent notamment une roue principale 9, des roulettes 11 , et une surface 13 de fond du châssis 7 permettant au feu de signalisation 1 de reposer au sol en position statique. Figures 1 to 7 show a mobile site traffic light 1 according to a first embodiment, comprising a light head 3 equipped with one or more light signals 5, and a frame 7 provided with ground connection members. The ground connection members include in particular a main wheel 9, casters 11, and a bottom surface 13 of the frame 7 allowing the signal light 1 to rest on the ground in a static position.
Le châssis 7 est avantageusement fabriqué en plastique roto moulé. La tête de feu 3 est reliée au châssis 7 par une liaison pivot au tour d’un axe X3, la tête de feu 3 étant mobile en rotation par rapport au châssis 7 entre une position dépliée, représentée aux figures 1 et 2, et une position repliée représentée aux figures 3 et 4. Le châssis 7 définit un volume de réception V7 de la tête de feu 3 en position repliée, dans laquelle la tête de feu 3 ne dépasse pas du volume de réception V7. Ainsi la tête de feu 3 peut être entièrement escamotée dans le châssis 7 en configuration repliée pour le transport dans un véhicule ou le rangement dans un local, la hauteur du feu de signalisation 1 étant considérablement réduite dans cette configuration par rapport à la position dépliée. Le repli de la tête de feu 3 dans le volume de réception V7 permet également de protéger la tête de feu 3. The frame 7 is advantageously made of rotomoulded plastic. The fire head 3 is connected to the frame 7 by a pivot connection around an axis X3, the fire head 3 being movable in rotation relative to the frame 7 between an unfolded position, shown in Figures 1 and 2, and a folded position shown in Figures 3 and 4. The frame 7 defines a receiving volume V7 of the fire head 3 in the folded position, in which the fire head 3 does not protrude from the receiving volume V7. Thus the light head 3 can be fully retracted into the frame 7 in the folded configuration for transport in a vehicle or storage in a room, the height of the signal light 1 being considerably reduced in this configuration compared to the unfolded position. The folding of the fire head 3 in the reception volume V7 also makes it possible to protect the fire head 3.
Avant le repli de la tête de feu 3, des visières 50 amovibles équipant les signaux lumineux 5 peuvent être avantageusement retirées. Before the fire head 3 is folded back, removable visors 50 fitted to the light signals 5 can advantageously be removed.
Une partie supérieure 70 du châssis 7 présente une surface plane 70A autour du volume de réception V7 de la tête de feu 3. Cette surface 70A s’étend sur deux parties latérales du châssis 7 situées de part et d’autre du volume de réception V7. Cette surface plane 70A permet d’empiler deux feux de signalisation 1 en configuration repliée comme cela est représenté à la figure 7. Dans un tel cas, la surface de fond 13 du feu de signalisation 1 située au-dessus repose sur la surface plane 70A du feu de signalisation 1 situé en-dessous. Ceci permet de réduire considérablement la surface au sol dans un lieu de stockage de feux de signalisation 1. En outre, d’autres objets, par exemple des planches, des outils, peut être posés sur les surfaces planes 70A. An upper part 70 of the frame 7 has a flat surface 70A around the receiving volume V7 of the fire head 3. This surface 70A extends over two lateral parts of the frame 7 located on either side of the receiving volume V7. . This flat surface 70A makes it possible to stack two traffic lights 1 in the folded configuration as shown in FIG. 7. In such a case, the bottom surface 13 of the signal light 1 located above rests on the flat surface 70A. traffic light 1 located below. This considerably reduces the floor space in a traffic light storage place 1. In addition, other objects, for example boards, tools, can be placed on the flat surfaces 70A.
Selon un aspect optionnel, le feu de signalisation 1 comprend des moyens de ralentissement de la rotation de la tête de feu 3 entre sa position dépliée et sa position repliée. Ces moyens de ralentissement évitent une rotation trop rapide de la tête de feu 3 vers sa position repliée et des éventuelles détériorations de la tête de feu 3 ou des signaux lumineux 5. Avantageusement, ces moyens de ralentissement permettent de contrôler la descente de la tête de feu 3 en résistant à la force de gravité. According to an optional aspect, the signal light 1 comprises means for slowing down the rotation of the light head 3 between its unfolded position and its folded position. These slowing means prevent too rapid rotation of the fire head 3 towards its folded position and possible damage to the fire head 3 or the light signals 5. Advantageously, these slowing means make it possible to control the descent of the fire head. fire 3 by resisting the force of gravity.
Dans un exemple représenté aux figures 5 et 6, le feu de signalisation 1 comporte une pièce de liaison 15 entre la tête de feu 3 et le châssis 7, cette pièce de liaison 15 étant fixe par rapport au châssis 7 et portant un arbre de rotation 17 de la tête de feu 3, qui est confondu avec l’axe de rotation X3. La pièce de liaison 15 est formée par deux ailes 150 parallèles et verticales, reliées par une base horizontale 152 fixée au châssis 7 par tout moyen approprié. La pièce de liaison 15 forme un « U ». Les deux ailes 150 et la base 152 forment un espace 154 dans lequel est situé un mât 30 de la tête de châssis 3. Le mât 30 a la possibilité de tourner dans l’espace 154 autour de l’axe X3. La pièce de liaison 15 peut être réalisée en deux parties, formant chacune un demi-U, divisées au milieu de la base 152, ou bien être réalisée d’une seule pièce monobloc, par exemple en tôle métallique pliée. In an example shown in Figures 5 and 6, the signal light 1 comprises a connecting piece 15 between the light head 3 and the frame 7, this connecting piece 15 being fixed relative to the frame 7 and carrying a rotation shaft 17 of the light head 3, which coincides with the axis of rotation X3. The connecting piece 15 is formed by two parallel and vertical wings 150, connected by a horizontal base 152 fixed to the frame 7 by any suitable means. The connecting piece 15 forms a "U". The two wings 150 and the base 152 form a space 154 in which is located a mast 30 of the frame head 3. The mast 30 has the possibility of rotating in the space 154 around the axis X3. The connecting piece 15 can be made in two parts, each forming a half-U, divided in the middle of the base 152, or else be made in one single piece, for example in folded sheet metal.
Les moyens de ralentissement sont formés par une rainure circulaire 156 prévue sur la pièce de liaison 15, plus particulièrement sur l’une des ailes 150 ou bien sur chacune d’elles, et par un pion 32 solidaire de la tête de feu 3, le pion 32 se déplaçant dans la rainure circulaire 156. La rainure 156 décrit une portion de cercle. La tête de feu 3 peut comprendre deux pions 32 configurés pour se déplacer chacun dans une rainure 156 ménagée dans chacune des ailes 150. Cette rainure circulaire 156 présente des crans 156A, distribués le long de la portion de cercle décrite par la rainure 156. Le pion 32 est entraîné dans ces crans 156A par un ressort 19 (représenté schématiquement aux figures 5 et 6) monté entre le pion 32 et l’arbre de rotation 17, et qui attire le pion 32 vers l’arbre de rotation 17 de manière que le pion 32 est automatiquement entraîné dans les crans 156A par le ressort 19, ralentissant la rotation de la tête de feu 3 vers sa position repliée. The slowing means are formed by a circular groove 156 provided on the connecting piece 15, more particularly on one of the wings 150 or else on each of them, and by a pin 32 integral with the fire head 3, the pin 32 moving in the circular groove 156. The groove 156 describes a portion of a circle. The light head 3 can comprise two pins 32 configured to move each in a groove 156 formed in each of the wings 150. This circular groove 156 has notches 156A, distributed along the portion of a circle described by the groove 156. The circular groove 156 has notches 156A, distributed along the portion of a circle described by the groove 156. The pin 32 is driven in these notches 156A by a spring 19 (shown schematically in Figures 5 and 6) mounted between the pin 32 and the rotation shaft 17, and which attracts the pin 32 towards the rotation shaft 17 so that the pin 32 is automatically driven into the notches 156A by the spring 19, slowing the rotation of the fire head 3 towards its folded position.
La rainure circulaire 156 comprend une encoche terminale inférieure 156B, dans laquelle le pion 32 est reçu en position dépliée de la tête de feu 3, et une encoche terminale 156C supérieure dans laquelle le pion 32 est reçu en position repliée de la tête de feu 3. The circular groove 156 comprises a lower end notch 156B, in which the pin 32 is received in the unfolded position of the fire head 3, and an upper end notch 156C in which the pin 32 is received in the folded position of the fire head 3. .
Le pion 32 est configuré pour être dégagé des encoches 156B et 156C de la rainure circulaire 156 par une poussée sur la tête de feu 3 en direction de l’axe de rotation X3, selon la flèche F1 à la figure 5, à l’encontre de la force du ressort 19. Ainsi lorsque l’on souhaite mettre le feu de signalisation 1 en position repliée, on appuie sur la tête de feu 3 pour dégager le pion 32 de l’encoche 156B et permettre son déplacement dans la rainure 156 selon la flèche F2, via les crans 156A, jusqu’à l’encoche 156C. De même pour débloquer la tête de feu de sa position repliée, il est nécessaire d’exercer une poussée pour dégager le pion 32 de l’encoche 156C. Il ne peut donc pas y avoir de rotations intempestives de la tête de feu 3, notamment de sa position dépliée vers sa position repliée. The pin 32 is configured to be disengaged from the notches 156B and 156C of the circular groove 156 by a thrust on the fire head 3 in the direction of the axis of rotation X3, according to the arrow F1 in FIG. 5, against of the force of the spring 19. Thus when it is desired to put the signal light 1 in the folded position, the light head 3 is pressed to release the pin 32 from the notch 156B and allow its movement in the groove 156 according to arrow F2, via notches 156A, up to notch 156C. Likewise, to unlock the fire head from its folded position, it is necessary to exert a push to release the pin 32 from the notch 156C. There can therefore be no untimely rotations of the light head 3, in particular from its unfolded position to its folded position.
Selon un aspect optionnel visible à la figure 5, le feu de signalisation 1 peut comprendre un organe de serrage rapide 21 permettant la réduction des jeux mécaniques entre la pièce de liaison 15 et le mât 30 en position dépliée. Cet organe de serrage 21 peut comprendre une poignée mobile 23 permettant de resserrer, à l’aide d’une tige 25 passant à travers les ailes 150 et dans l’espace 154, les ailes 150 contre les faces du mât 30. Un contact surfacique est alors exercé entre les ailes 150 et le mât 30, réduisant les jeux mécaniques et améliorant la stabilité de la tête de feu 3 en position dépliée. According to an optional aspect visible in FIG. 5, the signal light 1 can comprise a quick clamping member 21 allowing the reduction of the mechanical clearances between the connecting piece 15 and the mast 30 in the unfolded position. This clamping member 21 may include a movable handle 23 making it possible to tighten, using a rod 25 passing through the wings 150 and in the space 154, the wings 150 against the faces of the mast 30. A surface contact is then exerted between the wings 150 and the mast 30, reducing the mechanical games and improving the stability of the fire head 3 in the unfolded position.
Selon un aspect optionnel visible à la figure 7, le châssis 7 peut comprendre une surface de butée 74 coopérant avec une partie de la tête de feu 3 pour empêcher celle-ci de se déplacer vers l’avant du châssis 7, c’est-à-dire à l’opposé de l’axe de rotation X3, en position repliée. Selon une autre variante non représentée, la rainure 156 peut ne pas comprendre les crans 156A, mais seulement les encoches 156B et 156C. According to an optional aspect visible in FIG. 7, the frame 7 can comprise a stop surface 74 cooperating with a part of the light head 3 to prevent the latter from moving towards the front of the frame 7, that is to say. that is to say opposite the axis of rotation X3, in the folded position. According to another variant not shown, the groove 156 may not include the notches 156A, but only the notches 156B and 156C.
Selon une autre variante non représentée, une surface 72 de fond du volume de réception V7 peut comprendre des organes d’amortissement de la tête de feu 3, évitant des chocs sur la tête de feu 3 lorsque celle-ci arrive en position repliée. Ces organes d’amortissement peuvent prendre toute forme ou matière adaptée, telle que des blocs de mousse synthétique, des pièces en caoutchouc, etc. According to another variant not shown, a bottom surface 72 of the receiving volume V7 can include damping members for the fire head 3, avoiding impacts on the fire head 3 when the latter arrives in the folded position. These damping members can take any suitable shape or material, such as blocks of synthetic foam, rubber parts, etc.
On décrit à présent des deuxième, troisième, quatrième et cinquième mode de réalisation du feu de signalisation, en référence aux figures 8 à 11. Dans les deuxième à cinquième modes de réalisation, les éléments analogues à ceux du premier mode de réalisation portent les mêmes références et fonctionnement de la même façon. Dans ce qui suit, on décrit principalement les différences entre chaque mode de réalisation et le ou les précédents. Second, third, fourth and fifth embodiments of the traffic light are now described, with reference to FIGS. 8 to 11. In the second to fifth embodiments, elements similar to those of the first embodiment bear the same elements. references and operation in the same way. In what follows, the differences between each embodiment and the previous one or more are mainly described.
Une des principales différences entre les premier et deuxième modes de réalisation, est que, dans le deuxième mode de réalisation représenté à la figure 8, les moyens de ralentissement de la rotation de la tête de feu 3 entre sa position dépliée et sa position repliée sont formés par un vérin 200. One of the main differences between the first and second embodiments is that, in the second embodiment shown in FIG. 8, the means for slowing down the rotation of the fire head 3 between its unfolded position and its folded position are formed by a cylinder 200.
Le vérin 200 est configuré pour ralentir la rotation de la tête de feu 3 lors de sa descente en exerçant un effort sur le mât 30 s’opposant à la force de gravité. The cylinder 200 is configured to slow the rotation of the fire head 3 during its descent by exerting a force on the mast 30 opposing the force of gravity.
Ainsi, le vérin 200 accompagne la rotation de la tête de feu 3. Thus, the jack 200 accompanies the rotation of the fire head 3.
Le vérin 200 est par exemple un vérin à gaz, autrement dénommé ressort à gaz, qui présente l’avantage de ne pas nécessiter d’alimentation en énergie pour fonctionner. Ainsi, le ralentissement de la rotation de la tête de feu 3 lors de sa descente est réalisée sans intervention d’un utilisateur et sans apport d’énergie extérieur, ce qui est avantageux. The actuator 200 is for example a gas spring, otherwise referred to as a gas spring, which has the advantage of not requiring a power supply to operate. Thus, the slowing down of the rotation of the fire head 3 during its descent is achieved without user intervention and without external energy input, which is advantageous.
Selon un autre exemple, le vérin 200 est un vérin électrique. Dans un tel exemple, le vérin 200 est alors configuré pour accompagner la rotation de la tête de feu 3 entre sa position dépliée et sa position repliée, c’est-à-dire lors de sa descente, en diminuant le poids apparent de la tête de feu, mais également faciliter la rotation de la tête de feu 3 entre sa position repliée et sa position dépliée, c’est-à-dire lors de sa montée, en diminuant également le poids apparent de la tête de feu 3. According to another example, the jack 200 is an electric jack. In such an example, the jack 200 is then configured to accompany the rotation of the fire head 3 between its unfolded position and its folded position, that is to say during its descent, by reducing the apparent weight of the head. light, but also facilitate the rotation of the fire head 3 between its folded position and its unfolded position, that is to say during its ascent, also reducing the apparent weight of the fire head 3.
Ainsi, lorsque le vérin 200 est un vérin électrique, la rotation de la tête de feu 3 autour de l’axe de rotation X3 est facilitée d’une part lors de la descente de la tête de feu 3 et d’autre part lors de sa montée. Thus, when the jack 200 is an electric jack, the rotation of the fire head 3 around the axis of rotation X3 is facilitated on the one hand during the descent of the fire head 3 and on the other hand when its rise.
Une des principales différences entre d’une part les premier et deuxième modes de réalisation et d’autre part le troisième mode de réalisation représenté à la figure 9, est que, dans le troisième mode de réalisation, les moyens de ralentissement de la rotation de la tête de feu 3 entre sa position dépliée et sa position repliée sont formés par un dispositif à friction 300, représenté à la figure 9. One of the main differences between the first and second embodiments on the one hand and the third embodiment shown in FIG. 9 on the other hand, is that, in the third embodiment, the means for slowing down the rotation of the fire head 3 between its unfolded position and its folded position are formed by a friction device 300, shown in Figure 9.
À la figure 9, une partie de la pièce de liaison 15 est omise pour rendre visible le dispositif à friction 300. In Figure 9, part of the connecting piece 15 is omitted to make the friction device 300 visible.
Le dispositif à friction 300 comprend au moins une plaque mobile 302, dans l’exemple deux plaques mobiles 302, et au moins une plaque fixe 304, dans l’exemple deux plaques fixes 304. The friction device 300 comprises at least one movable plate 302, in the example two movable plates 302, and at least one fixed plate 304, in the example two fixed plates 304.
En pratique, chaque plaque mobile 302 est solidaire du mât 30 de la tête de feu 3 et chaque plaque fixe 304 est solidaire de la pièce de liaison 15. In practice, each movable plate 302 is integral with the mast 30 of the fire head 3 and each fixed plate 304 is integral with the connecting piece 15.
De plus, chaque plaque mobile 302 est en contact avec une plaque fixe 304. In addition, each movable plate 302 is in contact with a fixed plate 304.
Ainsi, lorsque la tête de feu 3 est mise en rotation autour de l’axe X3 pour passer de sa position dépliée à sa position repliée, chaque plaque mobile 302 frotte sur une plaque fixe 304. Les frottements entre les plaques fixes et mobiles génèrent un couple de frottement entre le mât 30 et la pièce de liaison 15 qui s’oppose mouvement de descente de la tête de feu 3, permettant ainsi de limiter la vitesse de rotation de la descente de la tête de feu. Thus, when the fire head 3 is rotated around the axis X3 to pass from its unfolded position to its folded position, each movable plate 302 rubs against a fixed plate 304. The friction between the fixed and movable plates generates a friction torque between the mast 30 and the connecting piece 15 which opposes the downward movement of the fire head 3, thus making it possible to limit the speed of rotation of the descent of the fire head.
En outre, dans le troisième mode de réalisation, le feu de signalisation 1 comprend également au moins un pion 306, de préférence deux pions 306. Chaque pion 306 est configuré pour s’engager dans une encoche 308 d’une plaque mobile 302 et dans une encoche 310 de la plaque fixe 304 en contact avec cette plaque mobile, lorsque la tête de feu 3 est en position dépliée, de sorte à empêcher la rotation de la tête de feu et ainsi verrouiller la position dépliée de la tête de feu. Further, in the third embodiment, the traffic light 1 also comprises at least one pin 306, preferably two pins 306. Each pin 306 is configured to engage in a notch 308 of a movable plate 302 and in a notch 310 of the fixed plate 304 in contact with this movable plate, when the fire head 3 is in the unfolded position, so as to prevent the rotation of the fire head and thus lock the unfolded position of the fire head.
Un avantage du troisième mode de réalisation est de ne pas nécessiter d’intervention d’un utilisateur et ni d’apport d’énergie extérieur pour ralentir la rotation de la tête de feu 3. An advantage of the third embodiment is that it does not require user intervention and no external energy input to slow the rotation of the fire head 3.
Un autre avantage du troisième mode de réalisation est d’être utilisable en environnement de chantier, par exemple dans un environnement subissant de fortes variations de températures et/ou pollué par des particules, telles que du sable, car le dispositif de friction 300 est robuste et fiable. Another advantage of the third embodiment is that it can be used in a work site environment, for example in an environment subject to strong variations in temperature and / or polluted by particles, such as sand, because the friction device 300 is robust. and reliable.
Une des principales différences entre d’une part les premier, deuxième et troisième modes de réalisation et d’autre part le quatrième mode de réalisation représenté à la figure 10, est que, dans le quatrième mode de réalisation, les moyens de ralentissement de la rotation de la tête de feu 3 entre sa position dépliée et sa position repliée sont formés par un mécanisme à pédale 400. Le mécanisme à pédale 400 comprend une pédale 402, un levier 404 qui comprend une première extrémité 406 à laquelle la pédale 402 est fixée et une deuxième extrémité 408. One of the main differences between on the one hand the first, second and third embodiments and on the other hand the fourth embodiment shown in FIG. 10, is that, in the fourth embodiment, the means for slowing down the rotation of the fire head 3 between its unfolded position and its folded position are formed by a pedal mechanism 400. The pedal mechanism 400 includes a pedal 402, a lever 404 which includes a first end 406 to which the pedal 402 is attached and a second end 408.
La deuxième extrémité 408 du levier 404 est en contact avec le mât 30 de la tête de feu 3. The second end 408 of the lever 404 is in contact with the mast 30 of the fire head 3.
De plus, le levier 404 est guidé par un système de guidage, non-représenté, de sorte que le déplacement de la pédale 402 entraîne le déplacement du mât 30 par l’intermédiaire de la deuxième extrémité 408. In addition, the lever 404 is guided by a guide system, not shown, so that the movement of the pedal 402 causes the movement of the mast 30 through the second end 408.
À l’inverse, le déplacement du mât 30 entraîne le déplacement de la pédale 402. Ainsi, un utilisateur du feu de signalisation 1 peut contrôler, par exemple ralentir, la descente de la tête de feu 3 en exerçant un effort résistant sur la pédale 402, par exemple en appuyant avec un pied sur la pédale 402, de sorte à exercer un effort de ralentissement sur le mât 30 s’opposant à la gravité. Conversely, the movement of the mast 30 causes the movement of the pedal 402. Thus, a user of the traffic light 1 can control, for example slow down, the descent of the light head 3 by exerting a resistant force on the pedal. 402, for example by pressing with one foot on the pedal 402, so as to exert a slowing force on the mast 30 opposing gravity.
De même, grâce au mécanisme à pédale 400, il est possible de faciliter la montée de la tête de feu 3 de sa position repliée vers sa position dépliée, en exerçant un effort entraînant sur la pédale 402 de sorte à exercer un effort d’entrainement sur le mât 30. Likewise, thanks to the pedal mechanism 400, it is possible to facilitate the ascent of the fire head 3 from its folded position to its unfolded position, by exerting a driving force on the pedal 402 so as to exert a driving force. on the mast 30.
En outre, grâce à un mécanisme de verrouillage non-représenté, il est possible de bloquer la position de la pédale 402 et du levier 404 de sorte à verrouiller la position de la tête de feu 3, par exemple la position dépliée de la tête de feu. In addition, thanks to a locking mechanism not shown, it is possible to block the position of the pedal 402 and of the lever 404 so as to lock the position of the fire head 3, for example the unfolded position of the fire head. fire.
Dans l’exemple représenté, la pédale 402 est située à l’arrière du châssis 7. En variante non-représentée, la pédale 402 est située sur un côté du châssis 7. In the example shown, the pedal 402 is located at the rear of the frame 7. In a variant not shown, the pedal 402 is located on one side of the frame 7.
En variante non-représentée, la pédale 402 est remplacée par un levier d’actionnement, situé à l’arrière du châssis 7, ou sur un côté du châssis 7. In a variant not shown, the pedal 402 is replaced by an actuating lever, located at the rear of the frame 7, or on one side of the frame 7.
Une des principales différences entre, d’une part, les premier, deuxième, troisième et quatrième modes de réalisation, et d’autre part le cinquième mode de réalisation représenté à la figure 11 , est que, dans le cinquième mode de réalisation, les moyens de ralentissement de la rotation de la tête de feu 3 entre sa position dépliée et sa position repliée comprennent un motoréducteur 500. One of the main differences between, on the one hand, the first, second, third and fourth embodiments, and on the other hand the fifth embodiment shown in Fig. 11, is that, in the fifth embodiment, the means for slowing down the rotation of the fire head 3 between its unfolded position and its folded position comprise a geared motor 500.
Le motoréducteur 500 est en pratique un moteur, de préférence électrique, dont le châssis 502 est fixé à la pièce de liaison 15 et dont une sortie, non-visible à la figure 11 , est fixée au mât 30. The geared motor 500 is in practice a motor, preferably electric, the frame 502 of which is fixed to the connecting piece 15 and of which an outlet, not visible in FIG. 11, is fixed to the mast 30.
Le motoréducteur 500 est configuré pour entraîner le mât 30 en rotation autour de l’axe de rotation X3. En outre, selon le sens de fonctionnement du motoréducteur 500, le mât 30 est entraîné en rotation de sorte à faire monter la tête de feu 3, ou alors de sorte à faire descendre la tête de feu 3. Ainsi, le motoréducteur 500 génère un contrôle électromécanique qui permet d’entraîner, de façon contrôlée, la tête de feu 3 en rotation par rapport au châssis 7, depuis sa position dépliée vers sa position repliée ou depuis sa position repliée vers sa position dépliée. The geared motor 500 is configured to drive the mast 30 in rotation about the axis of rotation X3. In addition, depending on the direction of operation of the geared motor 500, the mast 30 is rotated so as to raise the light head 3, or else so as to lower the light head 3. Thus, the geared motor 500 generates an electromechanical control which makes it possible to drive, in a controlled manner, the fire head 3 in rotation with respect to the frame 7, from its unfolded position to its folded position or from its folded position to its unfolded position.
De préférence, le motoréducteur 500 est commandé par un utilisateur, soit à l’aide de boutons non-représentés situés sur le châssis 502, soit à distance, par exemple à l’aide d’une télécommande non-représentée. Preferably, the geared motor 500 is controlled by a user, either using buttons (not shown) located on the frame 502, or remotely, for example using a remote control (not shown).
Grâce au motoréducteur 500, la montée et la descente de la tête de feu 3 sont contrôlées sans nécessiter de manipulation de la tête de feu par un utilisateur et donc sans qu’un utilisateur ne doive fournir d’effort physique. La montée et la descente de la tête de feu 3 sont donc facilitées. Thanks to the gear motor 500, the ascent and descent of the fire head 3 are controlled without requiring manipulation of the fire head by a user and therefore without a user having to provide physical effort. The ascent and descent of the fire head 3 are therefore facilitated.
Les moyens de ralentissement de la rotation de la tête de feu 3 décrits dans le premier mode de réalisation, dans l’exemple du deuxième mode de réalisation où le vérin est un vérin à gaz, dans le troisième mode de réalisation et dans le quatrième mode de réalisation sont particulièrement avantageux, car ils permettent de contrôler la descente de la tête de feu 3 sans recourir à une source d’énergie extérieure. Le feu de signalisation 1 est donc autonome et utilisable en sécurité y-compris dans des environnements dépourvus d’alimentation en énergie. The means for slowing down the rotation of the fire head 3 described in the first embodiment, in the example of the second embodiment where the cylinder is a gas cylinder, in the third embodiment and in the fourth embodiment These embodiments are particularly advantageous because they make it possible to control the descent of the fire head 3 without resorting to an external energy source. The traffic light 1 is therefore autonomous and can be used safely, including in environments with no power supply.
Les moyens de ralentissement de la rotation de la tête de feu 3 décrits dans le premier mode de réalisation, dans le deuxième mode de réalisation et dans le troisième mode de réalisation sont particulièrement avantageux, car ils permettent de contrôler la descente de la tête de feu 3 de manière passive, c’est-à-dire sans action spécifique d’un utilisateur. En effet, ces moyens de ralentissement fonctionnent de manière automatique, de sorte qu’un utilisateur souhaitant descendre la tête de feu 3 doit simplement entraîner le mouvement de descente de la tête de feu. The means for slowing down the rotation of the fire head 3 described in the first embodiment, in the second embodiment and in the third embodiment are particularly advantageous, since they make it possible to control the descent of the fire head. 3 passively, that is to say without specific action by a user. Indeed, these slowing means operate automatically, so that a user wishing to lower the fire head 3 simply has to cause the fire head to descend.
Les moyens de ralentissement de la rotation de la tête de feu 3 décrits dans le premier mode de réalisation, dans le troisième mode de réalisation et dans le quatrième mode de réalisation sont particulièrement avantageux, car ils permettent de contrôler la descente de la tête de feu 3 y-compris lorsque le feu de signalisation 1 est installé dans un milieu complexe, par exemple dans un milieu pollué par des particules telles que du sable ou dans un milieu subissant de fortes variations de température ou soumis à l’eau. En effet, ces moyens de ralentissement sont robustes et fiables et ne sont pas sensibles aux conditions environnementales. The means for slowing down the rotation of the fire head 3 described in the first embodiment, in the third embodiment and in the fourth embodiment are particularly advantageous, since they make it possible to control the descent of the fire head. 3 including when the traffic light 1 is installed in a complex environment, for example in an environment polluted by particles such as sand or in an environment subject to strong variations in temperature or subjected to water. Indeed, these deceleration means are robust and reliable and are not sensitive to environmental conditions.
