Description
La présente invention concerne un dispositif perfectionné supportThe present invention relates to an improved support device
d'élément de mobilier urbain escamotable. retractable street furniture element.
Parmi les dispositifs actuellement en service, il sera plus particulièrement fait référence à ceux qui comprennent, en premier lieu, un caisson disposé dans le sol, en deuxième lieu, un ensemble mobile logé dans ce caisson et comportant un plateau support d'un élément de mobilier urbain, qui est mobile entre une position haute dans laquelle l'élément de mobilier urbain émerge du caisson au-dessus du sol et une position basse dans laquelle cet élément de mobilier urbain est escamoté à l'intérieur du caisson de manière que sa partie supérieure ne dépasse pas le niveau du sol, et, en troisième lieu, des moyens d'actionnement pour déplacer l'élément mobile entre ces deux positions. Among the devices currently in use, it will be more particularly referred to those which comprise, first, a box disposed in the ground, secondly, a movable assembly housed in this box and having a support plate of a component of urban furniture, which is movable between a high position in which the urban furniture element emerges from the box above the ground and a low position in which this piece of street furniture is retracted inside the box so that its part higher does not exceed the ground level, and thirdly, actuating means for moving the movable element between these two positions.
Dans le document FR-2705979-A, les moyens d'actionnement sont constitués, d'une part, par un ensemble moto-réducteur alimenté électriquement et, d'autre part, par une sangle s'enroulant à chaque extrémité d'un arbre. L'ensemble moto-réducteur comprend un frein électromagnétique qui a pour but de maintenir l'ensemble mobile en position haute. Cet ensemble motoréducteur est réversible: il peut être entraîné en sens inverse sous l'effet de la masse de l'ensemble mobile comportant l'élément de mobilier urbain dès que le frein éléctro-magnétique n'est plus maintenu en position fermée. C'est cette réversibilité qui permet d'obtenir une borne escamotable à sécurité positive. Par sécurité positive il faut entendre qu'en cas de panne en alimentation électrique, l'ensemble mobile, s'il est en position haute, redescend immédiatement en position basse, par simple gravité et, donc, sans nécessiter l'apport d'une quelconque énergie. In the document FR-2705979-A, the actuating means are constituted, on the one hand, by an electrically powered geared motor assembly and, on the other hand, by a strap winding at each end of a shaft . The geared motor assembly comprises an electromagnetic brake which aims to keep the mobile assembly in the high position. This geared motor assembly is reversible: it can be driven in the opposite direction under the effect of the mass of the moving assembly comprising the street furniture element as soon as the electromagnetic brake is no longer maintained in the closed position. It is this reversibility that makes it possible to obtain a retractable bollard with positive security. For positive security, it must be understood that in the event of a breakdown in the power supply, the mobile unit, if it is in the high position, immediately drops back to the low position, by simple gravity and, therefore, without requiring the provision of a any energy.
Dans le mode de réalisation décrit dans ce dernier document, l'ensemble moto-réducteur fait partie intégrante de l'ensemble mobile: l'élément de mobilier urbain est donc directement fixé sur lui. Ceci a notamment pour conséquence, lors des chocs souvent violents que reçoit l'élément de mobilier urbain en position haute, d'endommager l'ensemble moto-réducteur; cette disposition réduit par conséquent fortement la résistance et la fiabilité fonctionnelle de ce dispositif de l'art antérieur et, par làmême, alourdit les coûts de son entretien. In the embodiment described in the latter document, the geared motor unit is an integral part of the moving assembly: the urban furniture element is therefore directly attached to it. This has the particular consequence, during often violent shocks that receives the urban furniture element in the high position, damaging the geared motor assembly; this arrangement therefore greatly reduces the strength and functional reliability of this device of the prior art and, thereby, increases the costs of its maintenance.
Aussi un des buts de la présente invention est-il de fournir un dispositif perfectionné support d'élément de mobilier urbain escamotable du genre ci-dessus, qui permet de pallier les inconvénients rapportés. It is therefore an object of the present invention to provide an improved retractable street furniture element support device of the above kind, which overcomes the reported disadvantages.
Un autre but est de fournir un tel dispositif qui permet d'intervenir sur l'en-35 semble moto-réducteur de façon aisée et sans risque. Another purpose is to provide such a device that allows to intervene on the en-35 seems motor-gearbox in an easy and risk-free way.
Ces buts, ainsi que d'autres qui apparaîtront par la suite, sont atteints par un dispositif perfectionné support d'élément de mobilier urbain escamotable comprenant, en premier lieu, un caisson disposé dans le sol, en deuxième lieu, un ensemble mobile logé dans ce caisson et comportant un plateau support d'un élément de mobilier urbain, qui est mobile entre une position haute dans laquelle l'élément de mobilier urbain émerge du caisson au-dessus du sol et une position basse dans laquelle cet élément de mobilier urbain est escamoté à l'intérieur du caisson de manière que sa partie supérieure ne dépasse pas le niveau du sol, et, en troisième lieu, des moyens d'actionnement pour déplacer l'ensemble mobile entre ces deux positions, lequel dispositif est caractérisé, selon la présente invention, par le fait que, d'une part, le caisson comporte un logement latéral débouchant à la surface du sol, et que, d'autre part, les moyens d'actionnement comprennent, d'une part, un ensemble moto- réducteur qui est situé dans ce logement latéral et qui est associé à un variateur de fréquence et, d'autre part, des moyens de trans- mission pour convertir le mouvement de rotation de cet ensemble moto- réducteur en un mouvement de translation de l'ensemble mobile entre sa position haute et sa position basse. These and other objects that will appear later are achieved by an improved retractable street furniture element support device comprising, firstly, a box disposed in the ground, secondly, a movable assembly housed in this box and comprising a support plate of an urban furniture element, which is movable between a high position in which the urban furniture element emerges from the box above the ground and a low position in which this item of street furniture is retracted inside the box so that its upper portion does not exceed the ground level, and, thirdly, actuating means for moving the movable assembly between these two positions, which device is characterized, according to the invention, in that on the one hand, the box has a lateral housing opening to the surface of the ground, and that, on the other hand, the actuating means comprise, a pa rt, a motor-gear unit which is located in this lateral housing and which is associated with a frequency converter and, secondly, transmission means for converting the rotational movement of this motor-reduction unit into a gearbox. translational movement of the movable assembly between its upper position and its lower position.
De préférence, les moyens de transmission sont constitués par une sangle dont une extrémité est solidaire de l'axe de l'ensemble moto-réducteur associé à un variateur de fréquence et l'autre extrémité est fixée au caisson en un point diamétralement opposé et qui coopère avec l'ensemble mobile. Preferably, the transmission means consist of a strap whose one end is integral with the axis of the geared motor assembly associated with a frequency converter and the other end is fixed to the box at a diametrically opposite point and which cooperates with the moving assembly.
La description qui va suivre et qui ne présente aucun caractère limitatif, doit être lue en regard de la figure unique annexée qui représente en coupe longitudinale verticale un dispositif support d'élément de mobilier urbain escamotable selon la présente invention. The following description, which has no limiting character, should be read in conjunction with the single appended figure which shows in vertical longitudinal section a retractable street furniture element support device according to the present invention.
Un tel dispositif comprend un caisson 1 de forme générale cylindrique qui est disposé dans un sol 2, un ensemble mobile 3 et des moyens d'actionnement 4. Such a device comprises a casing 1 of generally cylindrical shape which is disposed in a floor 2, a movable assembly 3 and actuating means 4.
L'ensemble mobile 3 est logé dans le caisson 1 et comporte un plateau support 5 sur lequel est fixé un élément de mobilier urbain 6 telle qu'une borne cylindrique: l'ensemble mobile 3 et le caisson 1 sont de même forme, le premier coulissant dans le second. Cet ensemble mobile 3 est mobile entre une position haute dans laquelle la borne 6 émerge du caisson 1 au-dessus du sol 2 et une position basse dans laquelle la borne 6 est escamotée à l'intérieur de ce caisson 1 de manière que sa partie supérieure ne dépasse pas le niveau du sol 2. The moving assembly 3 is housed in the casing 1 and comprises a support plate 5 on which is fixed a piece of street furniture 6 such as a cylindrical terminal: the moving assembly 3 and the casing 1 are of the same shape, the first sliding in the second. This mobile assembly 3 is movable between a high position in which the terminal 6 emerges from the box 1 above the floor 2 and a low position in which the terminal 6 is retracted inside this box 1 so that its upper part does not exceed ground level 2.
En position haute, le plateau support 5 est près de la surface du sol; en position basse, ce plateau support 5 est au plus près du fond du caisson 1. In the high position, the support plate 5 is close to the surface of the ground; in the low position, this support plate 5 is closer to the bottom of the box 1.
Selon la présente invention, le caisson 1 comporte un logement latéral 7 débouchant à la surface du sol 2 et de moindre profondeur que lui. Ce logement latéral 7 peut d'ailleurs être obturé par une trappe amovible 8 permettant d'accéder à son intérieur. According to the present invention, the box 1 comprises a lateral housing 7 opening on the surface of the ground 2 and of lesser depth than it. This lateral housing 7 can also be closed by a removable door 8 to access its interior.
Quant aux moyens d'actionnement, ils comprennent, d'une part, un ensemble moto-réducteur 9 qui est situé dans le logement latéral 7 et qui est associé à un variateur de fréquence et, d'autre part, des moyens de transmission pour convertir le mouvement de rotation du moteur en un mouvement de translation de l'ensemble mobile entre sa position haute et sa position basse. L'utilisation d'un ensemble moto-réducteur associé à un variateur de fréquence permet, entre autre chose, de répondre favorablement à la notion de sécurité positive exposée dans la norme NFP 98-310. As for the actuating means, they comprise, on the one hand, a geared motor assembly 9 which is located in the lateral housing 7 and which is associated with a frequency converter and, on the other hand, transmission means for converting the rotational movement of the motor into a translation movement of the movable assembly between its high position and its low position. The use of a geared motor assembly associated with a frequency converter makes it possible, among other things, to respond positively to the concept of positive security as described in the NFP 98-310 standard.
Ces moyens de transmission sont constitués par une sangle 10 dont une extrémité 10a est solidaire de l'axe de l'ensemble moto-réducteur 9 et l'autre extrémité 10b est fixée au caisson 1 en un point sensiblement diamétralement opposé et qui coopère avec le plateau support 5 de l'ensemble mobile. Ce dernier comporte, par exemple, des poulies 11 sous lesquelles passe la sangle 10. These transmission means consist of a strap 10, one end 10a of which is integral with the axis of the geared motor assembly 9 and the other end 10b is fixed to the box 1 at a substantially diametrically opposite point and which cooperates with the support plate 5 of the mobile assembly. The latter comprises, for example, pulleys 11 under which the strap 10 passes.
Lorsque l'ensemble mobile est en position basse, la sangle 10 est déployée 20 au maximum et la borne ne dépasse pas du sol: de préférence, le sommet de la borne affleure le sol 2. When the moving assembly is in the low position, the strap 10 is deployed to the maximum and the terminal does not protrude from the ground: preferably, the top of the terminal is flush with the ground 2.
Quand l'ensemble moto-réducteur 9 associé à un variateur de fréquence est alimenté, la sangle 10 s'enroule autour de l'axe du moteur, ce qui entraîne la montée de l'ensemble mobile 3 jusqu'à ce que la borne 6 soit en position haute. When the geared motor unit 9 associated with a frequency converter is powered, the strap 10 wraps around the axis of the motor, which causes the assembly of the mobile assembly 3 until the terminal 6 in the high position.
L'ensemble moto-réducteur 9 restant sous tension, la borne 6 reste en position haute. En inversant le sens de rotation de l'ensemble motoréducteur 9, la borne revient en position basse. The geared motor unit 9 remains energized, the terminal 6 remains in the high position. By reversing the direction of rotation of the geared motor assembly 9, the terminal returns to the low position.
En cas de coupure de l'alimentation électrique, la borne reste en position basse ou y revient par le principe même de réversibilité du motoréducteur 9: la 30 sécurité positive est ainsi respectée. In case of power failure, the terminal remains in the low position or returns to it by the very principle of reversibility of the geared motor 9: the positive security is thus respected.
En cas de choc, le fait que l'ensemble moto-réducteur 9 associé à un variateur de fréquence soit dans le logement latéral 7, le protège de toute atteinte directe ou indirecte. In the event of an impact, the fact that the geared motor assembly 9 associated with a frequency converter is in the lateral housing 7 protects it from any direct or indirect damage.
