Abstract
The bollard has an external shell (10) housing electrically powered lamps, and is fabricated from a durable plastic with a base plate (14). The latter is fixed to the road by bolts (16) which will shear easily under the impact of a motor vehicle colliding with the bollard. The base of the bollard is reinforced to ensure that the bolts break under impact. - The external walls of the bollard are fitted with translucent panels (20) on which is marked a traffic direction sign, or carry panels (22) which are covered with a strongly reflective material to increase their visibility.
Description
"Bornes de signalisation" "Bornes de signalisation".
La présente invention est relative, d'une façon générale, aux bornes de signalisation.
Une borne de signalisation comprend normalement un logement en tôle métallique , qui contient une source lumineuse pour éclairer un signal se trouvant à l'avant de la borne. Les deux côtés de cette borne sont également éclairés et une porte est prévue à l'arrière pour donner accès à la source lumineuse. La borne est fixée à un ilôt de trafic ou zone similaire grâce à des moyens tels que des boulons ancrés.
Un désavantage principal de telles bornes de signalisation est qu'elles sont facilement endommagées lorsqu'elles sont heurtées par un véhicule, ce qui a habituellement pour résultat des dégâts au logement en tôle métallique, à la source lumineuse et aux connexions électriques fournissant le courant à la borne.
Le but de l'invention est d'éviter le désavantage précédent.
La présente invention prévoit une borne de signalisation comprenant un logement fait d'une matière plastique durable, une plaque de base destinée à être fixée en place sur une route ou dans une rue, le logement étant fixé à la plaque de base par des boulons pouvant se cisailler facilement, de sorte que, si un véhicule heurte la borne, les boulons se cisailleront en libérant ainsi cette borne de sa fixation sur la route.
La section inférieure du logement est avantageusement renforcée pour aider au cisaillement des boulons.
Les faces externes du logement comportent des indications ou des signaux réalisés en une matière très réfléchissante.
A titre de variante, on peut prévoir une source lumineuse dans les limites de la plaque de base, et des panneaux translucides portant une indication ou un signal sont prévus sur le logement, de sorte que ces panneaux peuvent être illuminés par la source lumineuse se trouvant dans la plaque de base.
L'invention sera décrite plus complètement encore ci-après avec référence aux dessins non limitatifs annexés, qui illustrent deux formes de réalisation suivant l'invention.
La Figure 1 est une vue en perspective développée d'une borne de signalisation suivant l'invention, comportant un logement, un chapeau, un matériel de signalisation et une plaque de base. La Figure 2 est une vue en élévation de la borne de signalisation.
Les Figures 3 et 4 sont des vues latérales de cette même borne.
La Figure 5 est une vue en plan de la borne de signalisation. La Figure 6 est une vue en plan de la plaque de base. La Figure 7 montre diverses formes de signaux qui peuvent être incorporés dans la borne. La Figure 8 est une vue en perspective développée d'une source lumineuse incorporée dans la plaque de base de la seconde forme de réalisation susdite.
Si on se reporte aux dessins, la borne de signalisation comprend un logement 10, un chapeau 12 et une plaque de base 14. Le logement 10 et le chapeau 12 sont fabriqués en une matière plastique durable, par exemple en polyester renforcé par du verre. Le logement 10 est attaché à la plaque de base 14 grâce à quatre boulons en Nylon 16, pouvant se cisailler facilement, ces boulons pénétrant dans des trous complémentaires 17 et 18 prévus respectivement dans la plaque de base et dans le logement. Dans la section inférieure du logement 10, est incorporée une section en acier (non représentée) qui aide au cisaillement des boulons 16.
Les indications et les signaux de trafic, par exemple tels qu'illustrés par la Figure 7, sont incorporés dans la zone circulaire de signalisation 20 de la borne. La zone circulaire 20, le panneau rectangulaire frontal 22 et les panneaux rectangulaires 24, prévus suivant les côtés de la borne, sont tous fabriqués en une matière fortement réfléchissante. Les panneaux rectangulaires 24 prévus sur les côtés de la borne sont localisés vers la face avant de la borne de manière que le conducteur d'un véhicule s'approchant de celle-ci latéralement pourra savoir où se trouve l'avant de la borne. Des cavités peuvent être prévues sur la borne 10 pour recevoir le signal circulaire 20, ainsi que les panneaux rectangulaires
22 et 24.
Lors de l'utilisation, la plaque de base 14 est attachée à un ilôt de trafic, sur une route ou dans une rue, grâce à des boulons ancrés (non représentés), et le logement 10 est attaché à la plaque de base 14 par les boulons en Nylon 16. Si un véhicule heurte la borne, les boulons en Nylon 16 sont cisaillés, ce qui permet ainsi à la borne d'être chassée de la plaque de base 14 par ce véhicule. Ceci réduira les dégâts à la borne de sorte que le logement 10 pourra être ultérieurement refixé en place sur la plaque de base
14 en utilisant de nouveaux boulons 16.
La seconde forme de réalisation de borne de signalisation comprend la source lumineuse telle qu'illustrée par la Figure
8. Cette source lumineuse comprend un certain nombre de tubes fluorescents 32 prévus dans un logement 34 qui est logé dans la plaque de base 14 et fixé à celle-ci. Sur le haut du logement 34, est localisé un couvercle 36 qui comprend un panneau transparent
38 pour permettre une projection de la lumière vers le haut. La borne de cette seconde forme de réalisation diffère de celle de la première forme de réalisation par le fait que les panneaux 20,
22 et 24 sont fabriqués en polycarbonate translucide. Les panneaux en polycarbonate qui sont réalisés par sérigraphie sont ensuite attachés en place sur le loge m ent 10. Celui-ci est alors fixé sur la plaque de base 14 grâce à des boulons en Nylon 16. Comme les panneaux en polycarbonate sont translucides, la borne est illuminée de l'intérieur.
Si la borne est heurtée par un véhicule, les boulons 16 se cisailleront et le véhicule pourra se déplacer par-dessus la source lumineuse 30 sans l'endommager.
REVENDICATIONS.
1. Borne de signalisation, comprenant un logement fait en une matière plastique durable, une plaque de base destinée à être fixée en place sur une route ou dans une rue, ce logement étant fixé à la plaque de base par des boulons pouvant se cisailler facilement, de sorte que, si un véhicule heurte la borne, les boulons seront cisaillés en libérant ainsi la borne de sa fixation sur la route ou la rue.
"Signaling terminals" "Signaling terminals".
The present invention relates, in general, to signaling terminals.
A signaling terminal normally includes a sheet metal housing, which contains a light source to illuminate a signal located at the front of the terminal. The two sides of this bollard are also lit and a door is provided at the rear to give access to the light source. The bollard is fixed to a traffic island or similar zone by means such as anchored bolts.
A main disadvantage of such signaling posts is that they are easily damaged when struck by a vehicle, which usually results in damage to the sheet metal housing, the light source and the electrical connections supplying the current to terminal.
The object of the invention is to avoid the above disadvantage.
The present invention provides a signaling terminal comprising a housing made of a durable plastic material, a base plate intended to be fixed in place on a road or in a street, the housing being fixed to the base plate by bolts capable of shear easily, so that if a vehicle hits the bollard, the bolts will shear, freeing that bollard from its attachment to the road.
The lower section of the housing is advantageously reinforced to help shear the bolts.
The external faces of the housing include indications or signals made of a highly reflective material.
Alternatively, a light source may be provided within the limits of the base plate, and translucent panels carrying an indication or a signal are provided on the housing, so that these panels can be illuminated by the light source located in the base plate.
The invention will be described more fully still below with reference to the accompanying non-limiting drawings, which illustrate two embodiments according to the invention.
Figure 1 is a perspective view developed of a signaling terminal according to the invention, comprising a housing, a cap, signaling equipment and a base plate. Figure 2 is an elevational view of the signaling terminal.
Figures 3 and 4 are side views of this same terminal.
Figure 5 is a plan view of the signaling terminal. Figure 6 is a plan view of the base plate. Figure 7 shows various forms of signals that can be incorporated into the terminal. Figure 8 is a perspective view developed of a light source incorporated in the base plate of the second embodiment above.
Referring to the drawings, the signaling terminal comprises a housing 10, a cap 12 and a base plate 14. The housing 10 and the cap 12 are made of a durable plastic material, for example polyester reinforced with glass. The housing 10 is attached to the base plate 14 by means of four nylon bolts 16, which can be easily sheared, these bolts penetrating into complementary holes 17 and 18 provided respectively in the base plate and in the housing. In the lower section of the housing 10, there is incorporated a steel section (not shown) which assists in the shearing of the bolts 16.
The traffic indications and signals, for example as illustrated in FIG. 7, are incorporated in the circular signaling area 20 of the terminal. The circular area 20, the front rectangular panel 22 and the rectangular panels 24, provided along the sides of the terminal, are all made of a highly reflective material. The rectangular panels 24 provided on the sides of the terminal are located towards the front face of the terminal so that the driver of a vehicle approaching it laterally will be able to know where the front of the terminal is located. Cavities can be provided on terminal 10 to receive the circular signal 20, as well as the rectangular panels
22 and 24.
In use, the base plate 14 is attached to a traffic island, on a road or in a street, by anchored bolts (not shown), and the housing 10 is attached to the base plate 14 by the Nylon bolts 16. If a vehicle hits the bollard, the Nylon 16 bolts are sheared, thereby allowing the bollard to be driven from the base plate 14 by this vehicle. This will reduce damage to the terminal so that the housing 10 can later be reattached in place on the base plate
14 using new bolts 16.
The second embodiment of the signaling terminal comprises the light source as illustrated in the Figure
8. This light source comprises a number of fluorescent tubes 32 provided in a housing 34 which is housed in the base plate 14 and fixed thereto. On the top of the housing 34 is located a cover 36 which includes a transparent panel
38 to allow projection of the light upwards. The terminal of this second embodiment differs from that of the first embodiment in that the panels 20,
22 and 24 are made of translucent polycarbonate. The polycarbonate panels which are produced by screen printing are then attached in place on the housing m ent 10. This is then fixed to the base plate 14 with nylon bolts 16. As the polycarbonate panels are translucent, the bollard is illuminated from the inside.
If the bollard is struck by a vehicle, the bolts 16 will shear and the vehicle can move over the light source 30 without damaging it.
