Abstract

The fitting has a hemispherical cover (7) with a mirror (2) on the edge. Inside the cover is a lamp mounted on a base (12) and a ballast, capacitor and fuses. The equipment is mounted on a fork pivoted on the mirror edge (4) and held by a fixing (5) pressing on the edge (4). It also presses on the edge (6) of the cover (7). The equipment is hidden by a screen (18) also fixed on the fork. Another fork (8) turning on an axis in the centre of the mirror is combined with the movement of the first fork to direct the screen.

Description

De nombreux modèles de lanternes avec calotte à bord circulaire, équipées de miroir assymétrique sont fréquemment utilisées sur la voie publique pour donner un faisceau lumineux dirigé selon l'axe de la route. Souvent, dans ces modèles de lanternes , l'espace libre à l'intérieur même de la calotte est suffisant pour y loger l'appareillage constitué d'un ballast, d'un condensateur et des fusibles. Many models of lanterns with circular edge caps, equipped with asymmetrical mirror are frequently used on public roads to give a light beam directed along the axis of the road. Often, in these models of lanterns, the free space inside the cap itself is sufficient to accommodate the equipment consisting of a ballast, a capacitor and fuses.

Par contre, l'utilisation de ces lanternes est peu commode pour l'éclairage d'une place publique pour laquelle on recherche à la fois: des faisceaux lumineux de forme appropriée à la configuration des lieux et un nombre minimum de poteaux pour conserver une bonne accessibilité à l'endroit éclairé. On the other hand, the use of these lanterns is inconvenient for the lighting of a public place for which one seeks at the same time: light beams of a shape appropriate to the configuration of the places and a minimum number of poles to keep a good accessibility to the lit area.

Pour disposer de larges possibilités de réglage du flux lumineux, il est fréquent d'utiliser des lanternes -équipées de miroir à bord circulaire comme par exemple des lanternes à miroir semi-sphérique ou cylindro-parabolique pour lesquelles il est difficile de loger l'appareillage à l'intérieur de la lanterne. Pour ces lanternes à miroir symétrique par rapport à l'axe, l'appareillage est alors logé au pied du poteau, et, dans ce cas, l'encombrement des appareillages limite généralement le nombre de lanternes, montées par poteau, à deux très exceptionnellement à quatre. To have large possibilities of adjusting the luminous flux, it is frequent to use lanterns -equipped with mirror with circular edge like for example lanterns with semi-spherical or cylindro-parabolic mirror for which it is difficult to accommodate the apparatus inside the lantern. For these lanterns with mirror symmetrical with respect to the axis, the apparatus is then housed at the foot of the pole, and, in this case, the size of the apparatus generally limits the number of lanterns, mounted per pole, to two very exceptionally at four.

La présente invention est relative à une lanterne avec calotte à bord circulaire équipée d'un dispositif particulier assurant à la fois le logement de l'appareillage à l'intérieur de la lanterne et de multiples possibilités de réglage de flux lumineux. Cette disposition permet d'installer un grand nombre de lanternes par poteau. The present invention relates to a lantern with cap with circular edge equipped with a particular device ensuring both the housing of the apparatus inside the lantern and multiple possibilities for adjusting the luminous flux. This arrangement makes it possible to install a large number of lanterns per post.

L'invention est exposée plus en détail dans les figures suivantes:
La figure I est une vue en perspective d'un exemple d'exécution de la lanterne.The invention is explained in more detail in the following figures:
Figure I is a perspective view of an exemplary embodiment of the lantern.

La figure 2 est une coupe partielle de l'agrandissement de la partie A de la figure 1. FIG. 2 is a partial section of the enlargement of part A of FIG. 1.

Sur la figure 1, le dispositif représentant un exemple de réali- sation de l'invention se compose d'un étrier (1) pivotant au centre d' un miroir (2) à symétrie de révolution et nanti d'une plaquette (3) sur laquelle se monte l'appareillage non représenté. In FIG. 1, the device representing an exemplary embodiment of the invention consists of a stirrup (1) pivoting in the center of a mirror (2) with symmetry of revolution and provided with a plate (3) on which the apparatus, not shown, is mounted.

L'étrier (I) se prolonge au delà du bord (4) du miroir (2) par une partie coudée (5) aboutissant sur un rebord (6) d'une lanterne à calotte par exemple de forme semi-sphérique (7). Au centre, cet étrier (I) porte un premier cavalier (8) muni de fentes verticales (9) permettant le réglage en hauteur d'un second cavalier (10) muni de fentes horizontales (11) et portante son milieu un culot (12) pour recevoir une source lumineuse non représentée. Les fentes horizontales (11) permettent un réglage horizontal du culot (12) et l'intersection des fentes horizontales (11) et verticales (9) definissent un axe horizontal autour duquel le cavalier (10) portant le culot (12) peut pivoter. The stirrup (I) extends beyond the edge (4) of the mirror (2) by a bent part (5) ending on a ledge (6) of a lantern with a cap for example of semi-spherical shape (7) . In the center, this stirrup (I) carries a first jumper (8) provided with vertical slots (9) allowing the height adjustment of a second jumper (10) provided with horizontal slots (11) and carrying its base a base (12 ) to receive a light source not shown. The horizontal slots (11) allow horizontal adjustment of the base (12) and the intersection of the horizontal (11) and vertical (9) slots define a horizontal axis around which the rider (10) carrying the base (12) can pivot.

Avec ce dispositif, les possibilités de réglage du flux lumineux sont multiples. Par exemple, lorsque la source lumineuse est placée au centre de la lanterne, on obtient un flux diffusant circulaire, par contre, au fur et à mesure que l'on rapproche la source lumineuse du miroir on obtient un flux lumineux de plus en plus étroit, agissant comme un véritable projecteur dans la direction choisie selon l'orientation donnée à l'étrier (1). With this device, the possibilities of adjusting the luminous flux are multiple. For example, when the light source is placed in the center of the lantern, a circular diffusing flux is obtained, on the other hand, as the light source is brought closer to the mirror, an increasingly narrow luminous flux is obtained , acting like a real spotlight in the direction chosen according to the orientation given to the stirrup (1).

Le repérage de la position de l'étrier (1) est facilitée par un secteur gradué (13) situé au centre du miroir (2) et devant lequel se déplace l'étrier (1). Après réglage, les deux cavaliers (8 et 10) sont maintenus en place par un jeu de deux écrous (14). The location of the stirrup position (1) is facilitated by a graduated sector (13) located in the center of the mirror (2) and in front of which the stirrup (1) moves. After adjustment, the two jumpers (8 and 10) are held in place by a set of two nuts (14).

La figure 2 donne le détail de dispositif de verrouillage de étrier (1). Figure 2 shows the detail of the caliper locking device (1).

Sur la partie coudée (5) aboutissant au dessus du rebord intérieur (6) de la calotte semi-sphérique (7), se trouve une pièce (15) portant deux-épaulements (16) pourlui permettre de ne pas se détacher de la partie coudée (5) lorsque une vis de pression (17) est désserrée. On the bent part (5) ending above the inner rim (6) of the semi-spherical cap (7), there is a part (15) carrying two shoulders (16) to allow it not to detach from the part angled (5) when a pressure screw (17) is loosened.

Lorsque la vis de pression (17) est déserrée, on peut donner à étrier (1) l'orientation voulue en le faisant pivoter au centre du miroir (2).When the pressure screw (17) is loose, the stirrup (1) can be given the desired orientation by pivoting it in the center of the mirror (2).

En serrant la vis de pression (17) on rapproche la pièce (15) de la partie coudée (5) et on pince le rebord (4) du miroir (2) entre 1' étrier (1) et la pièce (15), immobilisant ainsi l'étrier (1) dans la position choisie.By tightening the pressure screw (17), the part (15) is brought closer to the bent part (5) and the flange (4) of the mirror (2) is clamped between the bracket (1) and the part (15), thus immobilizing the stirrup (1) in the chosen position.

L'appareillage, placé sur la plaquette (3) est dissimulé soit par un panneau (18), qui fait office de miroir et d'écran thermique pour protéger l'appareillage contre la chaleur émanant de la source lumineuse, soit par une surlargeur de l'étrier (1) qui remplit les mêmes fonctions.  The switchgear, placed on the plate (3) is concealed either by a panel (18), which acts as a mirror and thermal screen to protect the switchgear against the heat emanating from the light source, or by an extra width the stirrup (1) which performs the same functions.

L'appareillage placé sur la plaquette (3) est alimenté par un câble électrique, non représenté conduit le long de l'étrier (I) au départ du centre du miroir (2). De la sorte, quelle que soit la position de l'étrier (1) la longueur du cabale d'alimentation reste constante et empêche la formation de boucle contrariant le déplacement de 1' étrier. Dans cet exemple d'exécution, une vis (19), située au centre du miroir (2) et solidaire d'un pont, non représenté, inséré entre la calotte semi-sphérique (7) et le miroir (2), fait office d'axe de rotation autour duquel pivote l'étrier (1). The apparatus placed on the plate (3) is supplied by an electric cable, not shown, driven along the stirrup (I) from the center of the mirror (2). In this way, whatever the position of the stirrup (1), the length of the supply cabal remains constant and prevents the formation of a loop, which hinders the movement of the stirrup. In this exemplary embodiment, a screw (19), located in the center of the mirror (2) and secured to a bridge, not shown, inserted between the semi-spherical cap (7) and the mirror (2), acts axis of rotation about which the stirrup pivot (1).

Le démontage dé l'étrier (1) se fait avec grande facilité en enlevant la vis (19) et en desserrant la vis de pression (17) servant à la fixation périphérique de l'étrier (1).  Disassembly of the caliper (1) is done with great ease by removing the screw (19) and loosening the pressure screw (17) used for the peripheral fixing of the caliper (1).
