Definitions
- the present invention relates to an improved lamppost arm, and more particularly an arm fixed on one side to a support element, such as a lamppost mast or a wall, and supporting or being connected on the other side a unit of 'lighting.
- Public lighting devices comprising an arm, generally fixed approximately horizontally on a vertical support element such as a lamppost mast or a support wall, are well known in the state of the art.
- To make such complex structures use is made of fixed foundry arms, for example aluminum foundry or cast steel.
- This implementation has a number of drawbacks.
- an arm made in foundry has defined dimensions, different arm dimensions which cannot be produced by means of the same tool, but on the contrary different molds of different lengths are necessary to be able to make arms in foundry of variable lengths.
- the mechanical strength of a casting is not always optimal, especially when the structure is complicated and has areas of weakness, as is often the case with the lamppost arms.
- the object of the present invention is to provide a lamppost arm which does not have the abovementioned drawbacks.
- the present invention thus aims to provide a lamp post which is simple and inexpensive to manufacture and assemble.
- the present invention also aims to provide a floor lamp arm, making it possible to easily produce the floor lamp arms of any desired size and shape, with high mechanical strength.
- the present invention also aims to provide a modular lamp arm, that is to say that its shape and functionality can be transformed as desired, without having to manufacture each time a new arm. This is particularly important to cover with the same aesthetic the different models necessary for a global layout and which can be declined in different heights, number of lighting units, and therefore number of arms, as well as the length of these arms.
- the present invention therefore relates to a lamp post fixed on one side to a support element, such as a mast or a wall, and connected on the other side to a lighting unit, characterized in that said arm comprises a profile produced by spinning a material with high mechanical resistance with any constant cross section over the entire length of the arm.
- said arm has internal bosses defining a fictitious cylinder registered.
- said fictitious cylinder cooperates with a complementary cylindrical projection provided on or connected to said support element, to fix said arm to said support element.
- said arm is assembled on said support element.
- said arm includes reservations, adapted in particular to receive cables.
- said reservations are closed by removable closing means such as finishing plates.
- said arm comprises connection means, such as reservations or ribs, adapted to receive added external elements, provided with connection elements complementary to said connection means.
- said arm is fixed to the support element so as to form an angle between approximately 90 ° approximately 120 ° relative to said support element.
- said arm can be curved in its longitudinal direction.
- the present invention also relates to a street lighting street lamp comprising one or more arms as described above.
- FIG. 1 is a schematic cross-sectional view of an arm according to an advantageous embodiment of the present invention
- FIG. 2 is a view similar to Figure 1, showing another embodiment of the invention
- FIG. 5 is a schematic cross-sectional views of still other alternative embodiments of the present invention
- FIG. 5 is a schematic perspective view showing a public lighting device according to an advantageous embodiment of the invention, in which the arm has the section shown in FIG. 5,
- FIG. 7 is a schematic perspective view of a public lighting device according to another alternative embodiment
- FIG. 8 shows yet another alternative embodiment of the invention, in which the arm has the section shown in FIG. 1, and
- FIG. 9 also represents a schematic perspective view of another alternative embodiment of the invention, in which the arm has the section shown in FIG. 2.
- the public lighting devices conventionally comprise an arm 10, generally called a lamppost arm, which is fixed on one side to a support element 20, such as a lamppost mast, as shown in the Figures 6, 8 and 9, or a support wall, as shown in Figure 7.
- a support element 20 such as a lamppost mast, as shown in the Figures 6, 8 and 9, or a support wall, as shown in Figure 7.
- the arm 10 is connected to a lighting unit 30, which will not be described in more detail below since it is not directly linked to the invention.
- the arm 10 has a profile which is produced by spinning or extruding a material with high mechanical strength, in particular aluminum, and which has any constant cross section over the entire length of the arm.
- This implementation makes it possible to make lamppost arms of any length and any complex shape.
- several arms can be cut from the same extruded profile.
- the profile can also be machined after extrusion.
- the profile of the arm 10 comprises several internal bosses 11 which define contact surfaces 12 on their inner radial edge, which advantageously form a fictitious inscribed cylinder 13 inside the arm 10.
- bosses 11 improves on the one hand the resistance of the arm 10, and on the other hand allows, by means of the fictitious cylinder registered 13, to fix the arm on the support element 20, in particular by engaging said fictitious cylinder registered 13 on a complementary cylindrical projection (not shown) provided on or connected to said support element 20.
- said arm can also be screwed onto said support element, for example by means of threads made at the holes 15, and which make it possible to screw said arm 10 onto said support element 20.
- an advantageous characteristic of the invention consists in providing reservations or pre-machining 16, 17, which extend over the entire length of the arm 10.
- These reservations 16, 17 can be adapted to receive cables, in which case said reservations are advantageously closed by removable closing means 18, such as for example a plate or a finishing or termination cloth.
- these reservations 16, 17 can also be intended to receive and fix external elements reported such as decorations, which allow to easily modulate the desired external shape of said arm from a single central arm.
- the arm 10 can comprise connection or fixing means 16, 17, 19, which can therefore either be produced in the form of the aforesaid reservations 16, 17, or in the form of ribs 19, as shown in the figure 5.
- the added external elements 50 in this case comprise additional connection or fixing elements.
- the attached external element 50 which in this case is a decorative element, has a groove corresponding in shape to the external rib 19 of the arm 10, so that the element 50 can be clipped under the arm 10. Thanks to this modularity, any shapes, and very variable can be obtained without having to modify the machine for manufacturing said arm, by simple application of various external elements of equally arbitrary shapes.
- the arm 10 forms an angle ⁇ situated between 90 ° and 120 ° relative to to the support element 20.
- This angle ⁇ could be less than 90 ° (in which case the arm 10 would be inclined downward) or greater than 120 ° if desired.
- the arm 10 is curved in its longitudinal direction, while keeping a constant cross section.
- the present invention therefore provides an arm structure which simultaneously optimizes the following functions: - high mechanical strength by virtue of its seamless extruded aluminum profile, and which is not altered even if the arm is then machined to modify its aesthetics , - any external shapes, in particular geometrically complex, and in particular different from the usual smooth sections, such as round, square or rectangular profiles, - modular external forms, by means of added external elements,
