Description

Technical field of the invention

The present invention relates to the general field of lighting of public places and access roads. It relates more precisely to a public lighting pole provided with a decorative and / or informative part.

State of the art

For many years, public lighting poles (the term "pole" here designating not only a lighting pole but also a public lighting post) placed in particular along access routes can also be used in the framework. display of decorations and / or advertising or informative messages relating, for example, to events taking place in the town where said candelabra are installed. Such messages and / or decoration are conventionally placed on display devices (flag, semi-floating or floating flags, banners, etc.) which are then temporarily fixed along or on the top of the mast of these candelabra.

One of the drawbacks of these solutions is that they have a relatively high wind resistance which generates an application of strong stresses on the mast which supports them, which is not satisfactory.

Furthermore, another drawback of solutions such as floating panels is that, in addition to unsatisfactory aesthetics, their visibility turns out to be relatively poor for people passing nearby (motorists, pedestrians) due to the relative mobility of these panels. This problem is further accentuated during periods when the ambient light is low or even zero and when these floating panels are consequently difficult to read or even illegible. This is not satisfactory in particular from the point of view of the advertising or information impact.

Further, a drawback of such display devices is that the safety is not satisfactory because these devices are dependent on the environmental conditions. For example, panels can come off depending in particular on changing conditions (wind force, etc.). This can have consequences when an advertising flag ends up on the road.

Finally, still due to the nature of the current display devices, the messages are not durable over an extended period (month, season, year) because they do not withstand meteorological hazards, in particular linked to the wind.

Summary of the invention

The aim of the present invention is to provide a pole for public lighting candelabra provided with a decorative and / or informative part that is durable and always perfectly visible whatever the ambient light, said pole being modular, easy to install and particularly resistant. to stresses imposed by the wind in accordance with the requirements of European standard EN40.

Description of embodiments

With reference to figures 1 and 2 , the invention relates to a public lighting pole 1 supporting, generally near its upper part, at least one external lighting member, not shown in the figures, the latter being conventionally of the lantern or spotlight type and fixed directly on the mast 1 or indirectly by means of a complementary element fixed to said mast 1 and being of the bracket, crosshead, end piece, reducer, or even crown type, said external lighting member coming from the "standard" ranges manufacturers of public lighting equipment.

• un tronçon de base 2 agencé pour être fixé sur le sol,
• un tronçon intermédiaire 3 au moins en partie lumineux, et
• un tronçon de tête 4 supportant directement ou indirectement l'organe externe d'éclairage.

Said mast 1 comprises at least three sections assembled together, in a removable manner, namely from the bottom to the top of said mast 1:

• a base section 2 arranged to be fixed to the ground,
• an intermediate section 3 at least partly illuminated, and
• a head section 4 directly or indirectly supporting the external lighting member.

The base section 2 is designed to be fixed to the ground either by means of a base plate, commonly called a sole, welded to the lower end of said base section 2 and fixed to the ground using anchor plug or the like, or using an additional length intended to be directly sealed and embedded in the ground. Said base section 2 comprises at least one hollow barrel 5 made in a conventional manner from sheet metal and a removable inspection hatch 6 closing off an opening 7 made on the barrel 5 of said base section 2, equipped with various accessories, not shown , such as, for example, a fixing bar, or a locking system, and allowing the installation and connection of the electrical equipment, in particular the power cables of said external lighting member, but also the access subsequent to said electrical equipment.

• un premier fût 8 creux fabriqué de manière classique à partir de tôle métallique et muni d'au moins une découpe 9 aménagée sur ledit premier fût 8 de manière à traverser entièrement l'épaisseur de ce dernier et obtenue grâce à un procédé de découpe approprié tel que, par exemple, la découpe laser, plasma, ou encore par jet d'eau,
• un deuxième fût 10 creux translucide ou transparent inséré de façon ajustée à l'intérieur dudit premier fût 8, et
• un organe interne d'éclairage 11 disposé au moins en partie à l'intérieur dudit deuxième fût 10 et conformé pour faire passer la lumière émise par ledit organe interne d'éclairage 11 au travers successivement du deuxième fût 10 et de la découpe 9 du premier fût 8.

Intermediate section 3 comprises at least:

• a first hollow barrel 8 made in a conventional manner from sheet metal and provided with at least one cutout 9 arranged on said first barrel 8 so as to completely pass through the thickness of the latter and obtained by means of an appropriate cutting process such as that, for example, laser or plasma cutting, or even by water jet,
• a second translucent or transparent hollow barrel 10 fitted snugly inside said first barrel 8, and
• an internal lighting member 11 disposed at least in part inside said second shaft 10 and shaped to pass the light emitted by said internal lighting member 11 successively through the second shaft 10 and the cutout 9 of the first barrel 8.

The cutout (s) 9 can be any type of decoration and / or advertising or informative messages relating, for example, to events taking place in the town where the pole 1 of a public lighting candelabra is installed.

In order to be able, if necessary, to easily change the intermediate section 3 on a mast 1, the second barrel 10 and the internal lighting member 11 are fully integrated in the intermediate section 3, that is to say that their length respective is at most equal to that of said intermediate section 3.

The term "fitted in an adjusted manner" here denotes the fact that the second shank 10 of the intermediate section 3 of the pole 1 is shaped so that, when it is inserted into the first shank 8, its outer wall is pressed as closely as possible against the interior wall of said first barrel 8 so as to minimize the space between its exterior wall and the interior wall of said first barrel 8, while allowing light to pass through cutout 9 of first barrel 8.

Said head section 4 comprises a hollow barrel 12 made in a conventional manner from sheet metal.

According to an advantageous but non-limiting embodiment, the respective cross sections of the base section 2, of the intermediate section 3 and of the head section 4 are generally circular, and, with reference to figures 1 and 2 , the base 2 and head 4 sections are conical and the intermediate section 3 is cylindrical for obvious reasons of ease of manufacture.

The term “generally circular” denotes here the fact that each section has a cross section which may be in the shape of a totally or partially of a circle, of an ellipse or of a closed planar curve not comprising a right angle.

However, the respective cross section of the base section 2, of the intermediate section 3 and of the head section 4 may not be generally circular and the base 2 and head 4 sections may not be conical, without going beyond the scope of the present invention.

Furthermore, in order to have a mast 1 in accordance with the invention with a beautiful aesthetic appearance, it will be understood that the cross section of the lower and upper ends of the intermediate section 3 have dimensions respectively close to those of the cross section of the end. top section of base section 2 and those of the cross section of the lower end of head section 4.

The term “of similar dimensions” denotes here the fact that the various cross sections are homothetic and of similar dimensions but not necessarily strictly equal. Indeed, it is well understood that depending on the method of assembly of different sections 2, 3, 4 of the mast 1 (especially in the case of a joint), the dimensions of these different cross sections may be slightly greater or less.

With reference to figures 2 to 4 , according to an advantageous but non-limiting embodiment, the base section 2, the intermediate section 3 and the head section 4 are assembled together using external flanges 13,14,15 and screws 16. Thus, the base section 2 comprises an external flange 13 welded to its upper end and provided with at least one through hole 17, the intermediate section 3 comprises an external flange 14 welded to each of its ends and provided with at least one thread 18 non-opening, and the head section 4 comprises an external flange 15 welded to its lower end and provided with at least one orifice 19 passing through. To assemble the mast 1, a screw 16 is inserted into each hole 17 of the outer flange 13 of the base section 2 and into each hole 19 of the outer flange 15 of the head section 4 and they are screwed into a female thread. 18 of the external flange 14 associated with the intermediate section 3. To enhance the aesthetic appearance of the mast 1 according to the invention, each orifice 17 of the external flange 13 of the base section 2 and each orifice 19 of the external flange 15 of the section head 4 advantageously comprises a countersink 20 to embed the head of the screws 16.

With reference to figures 5 to 8 , the internal lighting member 11 comprises a hollow section 21 provided with a lower flange 22 disposed near its lower end and an upper flange 23 disposed near its upper end and at least one light source , not shown, disposed on the external face of said hollow section 21, preferably between said lower 22 and upper 23 flanges, and facing the cutout 9 of the first shaft 8 of the intermediate section 3, when the internal member lighting 11 is placed in said intermediate section 3. The hollow section 21 allows the passage of the power cables of or external lighting members while avoiding the creation of a shadow projected on the second translucent shaft 10 or transparent of the intermediate section 3. Moreover, in the hypothesis of a plurality of cutouts 9 arranged on the periphery of the first shaft 8 of the intermediate section 3, it is possible to obtain a homogeneous lighting, soft and without peak luminance s ur all or part of the length of the intermediate section 3 to 360 degrees. It is then understood that the cutout (s) 9 will always be perfectly visible whatever the ambient light.

In addition, the light source or sources are advantageously light-emitting diodes to obtain dynamic and configurable lighting.

According to an advantageous but non-limiting embodiment, the overall dimensions of the lower flange 22 of the hollow section 21 of the internal lighting member 11 are between the overall dimensions of the cross section of the interior wall of said first shaft 8 of the intermediate section 3 and the overall dimensions of the cross section of the outer wall of the second barrel 10 of the intermediate section 3, so that said hollow section 21 supports said second barrel 10. Furthermore, the overall dimensions of the upper flange 23 of the hollow profile 21 of the internal lighting member 11 are smaller than the overall dimensions of the cross section of the inner wall of the second shaft 10 of the intermediate section 3, so that the hollow profile 21 of the internal lighting member 11 can be inserted into said second barrel 10 by its upper flange 23. Said upper flange 23 of the hollow section 21 of the internal lighting member 11 e st shaped to be secured to the first shaft 8 of the intermediate section 3 by means, for example, of a fixing plate 24 welded into said first shaft 8 in the upper part. Finally, the second shaft 10 is such that its length advantageously less than the distance between the lower 22 and upper 23 flanges of the hollow section 21 of the internal lighting member 11.

Thus, with such a configuration, to assemble the intermediate section 3, the second barrel 10 is inserted into the first barrel 8, then the internal lighting member 11 is inserted into the first barrel 8 - second barrel 10 assembly until that the upper flange 23 of the hollow section 21 comes to bear against the fixing plate 24 of said first shaft 8 (Cf. figure 3 Finally, the upper flange 23 of the hollow profile 21 and the fixing plate 24 are secured together using, for example, screws. Incidentally, the lower flange 22 of the hollow section 21 may be in contact with the lower face of the second shaft 10. It is therefore understood that this assembly is particularly easy and rapid.

The pole 1 of a street lighting post according to the invention applies more particularly to the lighting of access roads, but it can also be used to illuminate public places such as, for example, shopping areas or public areas. pedestrian places.

Finally, it goes without saying that the examples of masts 1 in accordance with the invention which have just been described are only specific illustrations, in no way limiting the invention.
