Abstract

The opening (2) in the base of the column (1) is closed by an access door and the edges of the openings are set back towards the inside to extend perpendicular to the plan of the opening. The longitudinal opening edges are rectilinear and set back in rounded form. The transverse edges are cut following an arc and their set part has two profiles, a truncated part oblique with respect to the longitudinal axis of the post and a cylindrical part.

Description

perfectionnements apportés aux poteaux et aux mâts
Les poteaux ou mâts d'éclairage comportent à leur bass une ouverture normalement obturée par une porte de visite.
improvements to poles and masts
Lighting poles or masts have at their bottom an opening normally closed by an inspection door.

Jusqu'à présent, cette ouverture est formée par und simple découpe pratiquée dans la paroi du poteau. Up to now, this opening has been formed by a simple cutout made in the wall of the post.

La présente invention a pour objet un perfectionnement apporté aux poteaux ou mâts d'éclairage qui permet de diminuer notablement leur prix de revient. The present invention relates to an improvement made to lighting poles or masts which makes it possible to significantly reduce their cost price.

Selon la présente invention, les bords de l'ouverture du poteau sont rabattus vers l'intérieur de façon à s'étendre sensiblement perpendiculairement au plan de l'ouverture. According to the present invention, the edges of the opening of the post are folded inwards so as to extend substantially perpendicular to the plane of the opening.

Ces bords rabattus augmentent notablement la résistance du poteau à la flexion et à la torsion. Comme un poteau est principalement soumis à un effort de flexion, on peut, pour une même résistance à la flexion, diminuer l'épaissour de la paroi du poteau, donc le poids de la matière utilisée pour réaliser le poteau. Par ailleurs, ce rabattemen des bords évite tout risque de blessures. These folded edges significantly increase the resistance of the post to bending and twisting. As a post is mainly subjected to a bending force, it is possible, for the same flexural strength, to decrease the thickness of the wall of the post, therefore the weight of the material used to make the post. Furthermore, this folding of the edges avoids any risk of injury.

Les bords longitudinaux de l'ouverture, qui sont rectilignes, peuvent être rabattus suivant une forme arrondie. The longitudinal edges of the opening, which are straight, can be folded down in a rounded shape.

Les bords transversaux de cette ouverture sont généralement découpés suivant un arc, par exemple sensiblement semi-circulaire en se raccordant aux bords longitudinaux de ladite ouverture, de façon à éviter tout angle vif qui risquerait d'être à l'origine de fissures. The transverse edges of this opening are generally cut along an arc, for example substantially semicircular by connecting to the longitudinal edges of said opening, so as to avoid any sharp angle which might cause cracks.

Si l'on rabat ces bords transversaux en leur donnant une forme arrondie, l'expérience montre que l'allongement de la matière qui en résulte, produit des fissures. Pour remédier à ce défaut, il est avantageux de donner à ces bords transversaux une double cassure, le rabat comportant une partie tronconique oblique par rapport à l'axe longitudinal du poteau et une partie cylindrique qui est perpendiculaire à cet axe. If these transverse edges are folded down, giving them a rounded shape, experience shows that the elongation of the material which results therefrom produces cracks. To remedy this defect, it is advantageous to give these transverse edges a double break, the flap comprising a frustoconical part oblique to the longitudinal axis of the post and a cylindrical part which is perpendicular to this axis.

On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation d'un poteau d'éclairage selon l'invention aves référence au dessin annexé dans lequel :
La Figure 1 est une vue en élévation du poteau, au droit de la porte de visite, celle-ci n'étant pas représentée;
La Figure 2 en est une vue en coupe transversale suivant II-II de la figure I;
La Figure 3 en est une vue en coupe longitudinale suivant III-III de la Figure 1.
An embodiment of a lighting pole according to the invention has been described below, by way of nonlimiting example, with reference to the appended drawing in which:
Figure 1 is an elevational view of the post, to the right of the inspection door, the latter not being shown;
Figure 2 is a cross-sectional view along II-II of Figure I;
Figure 3 is a longitudinal section view along III-III of Figure 1.

Tel qu'il est représenté au dessin, le poteau 1 présente une forme conique et a une section circulaire; il est muni à sa partie inférieure d'une ouverture 2 susceptible d'être obturée par une porte 3. Celle-ci comporte un soyage ou feuillure inté- rieure 3a propre à s'engager dans l'ouverture 2 et sa largeur est telle que ses bords longitudinaux recouvrent les bords de l'ouverture 2. As shown in the drawing, the post 1 has a conical shape and has a circular section; it is provided at its lower part with an opening 2 capable of being closed by a door 3. The latter comprises an internal groove or rebate 3a suitable for engaging in the opening 2 and its width is such that its longitudinal edges cover the edges of the opening 2.

Les bords longitudinaux de l'ouverture 2 sont rectilignes et la paroi du poteau est, le long de ces bords, rabattue suivant une forme arrondie vers l'intérieur, comme indiqué en la, de façon à s'étendre sensiblement parallèlement au plan de symétrie X - X du poteau. The longitudinal edges of the opening 2 are rectilinear and the wall of the post is, along these edges, folded down in a rounded shape inwards, as indicated in la, so as to extend substantially parallel to the plane of symmetry X - X of the post.

Par contre , les bords transversaux de l'ouverture 2 sont sensiblement circulaires et se raccordent à ses bords longitudinaux. Le long de ces bords, la paroi du poteau est également rabattue vers l'intérieur. Mais ce rabat, au lieu d'être arrondi, comprend une partie tronconique lb oblique par rapport à l'axe longitudinal du poteau et une portion cylindrique 1.  On the other hand, the transverse edges of the opening 2 are substantially circular and are connected to its longitudinal edges. Along these edges, the wall of the post is also folded inward. However, this flap, instead of being rounded, comprises a frustoconical portion 1b oblique to the longitudinal axis of the post and a cylindrical portion 1.

Xl va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. C'est ainsi, en particulier, que le poteau pourrait Outre cylindrique et non pas tronconique; de même, sa section pourrait store octogonale.  Xl goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but covers, on the contrary, all variants. It is thus, in particular, that the post could be cylindrical and not frustoconical; similarly, its section could be octagonal blind.
