Abstract

The bollard (3) is able to slide inside a housing (1) between deployed and retracted positions. The housing contains a cover (4) with a central sleeve (12) which acts as a stop for the base of the bollard when it is deployed. The bollard incorporates at least one additional cover (10) with a sleeve (12) which fits on top of the first with its lower section engaged in the upper part of the first cover (13) and forming an extension to the first cover's sleeve. The first and second covers are linked by tubular spacers (9) with holes for long bolt fasteners.

Description

La présente invention concerne le domaine de la condamnation d'accès et plus particulièrement les bornes anti-intrusion pour véhicules.The present invention relates to the field of blocking access and more particularly the terminals anti-intrusion for vehicles.

On connaít des bornes escamotables qui, en service, constituent un obstacle au franchissement d'une certaine zone par un véhicule. Ces bornes se présentent sous la forme par exemple d'un cylindre métallique qui est montée à coulissement dans un corps de borne enterré de sorte que, hors-service, le cylindre est totalement enfoui avec son sommet affleurant le sol alors qu'en service, le cylindre est dressé au-dessus du sol sur une hauteur d'environ un mètre avec son pied encore maintenu dans le corps de borne.We know retractable bollards which, in service, constitute an obstacle to crossing a certain area by a vehicle. These terminals are presented in the form for example of a metal cylinder which is sliding mounted in a buried terminal body of so that, out of service, the cylinder is completely buried with its summit flush with the ground while in service, the cylinder is erected above the ground on a height about one meter with his foot still held in the terminal body.

Ces dispositifs doivent résister à un choc d'une forte intensité, correspondant par exemple à l'énergie d'un véhicule lancé à plusieurs dizaines de kilomètres/heure contre la borne. De manière préférée, cette résistance doit s'accompagner d'une absorption d'énergie contrôlée afin de maítriser limiter les déformations résultant de ce choc dans des zones déterminées du dispositif qu'il sera par exemple aisé de remplacer pour remettre l'appareil en état de marche. Par ailleurs, dans un souci de rationalisation de la fabrication, il est utile de pouvoir réaliser des bornes de caractéristiques mécaniques différentes avec, si possible, des pièces identiques.These devices must withstand a shock from a high intensity, corresponding for example to the energy of a vehicle launched at several tens of kilometers / hour against the terminal. Preferably, this resistance must be accompanied by a controlled energy absorption in order to control limit the deformations resulting from this shock in specific areas of the device that it will be easy example to replace to restore the device Steps. In addition, for the sake of rationalization of manufacturing, it is useful to be able to carry out terminals of different mechanical characteristics with, if possible, identical parts.

A cet effet, notamment, un dispositif de condamnation d'accès comprend une borne escamotable montée à coulissement dans un corps de borne situé sous le niveau du sol, entre une première position hors-service où une extrémité de la borne affleure le niveau du sol et une seconde position en-service où elle s'étend en saillie par rapport au niveau du sol, un premier couvercle rapporté présentant une chemise centrale cylindrique pour la borne formant un pseudo-encastrement de son pied lorsqu'elle est en service et un second couvercle rapporté sur le premier avec une chemise dont l'extrémité inférieure est emboítée dans la partie supérieure du premier couvercle en prolongement de la chemise de ce dernier. On augmente ainsi de manière simple la hauteur d'encastrement du pied de la borne dans le corps, élevant d'autant la résistance au choc latéral de celle-ci.To this end, in particular, a locking device access includes a retractable bollard mounted at sliding in a terminal body located below the level of the ground, between a first out-of-service position where a end of the terminal is flush with the ground level and a second in-service position where it extends by relative to ground level, a first attached cover having a central cylindrical jacket for the terminal forming a pseudo-embedding of his foot when it is in service and a second cover attached to the first with a shirt whose lower end is fitted in the upper part of the first cover in extension of the latter's shirt. This increases by simple way the installation height of the foot of the terminal in the body, thereby increasing the impact resistance side of it.

Dans un mode de réalisation préféré de l'invention, le second couvercle repose sur le premier couvercle par des entretoises tubulaires encastrées par leurs extrémités dans chacun des couvercles. Ces entretoises constituent des amortisseurs du choc latéral car, pour certaines d'entre elles, celles qui sont situées "derrière" la borne dans la direction du choc, le choc tendant à plier la borne entraíne une déformation en compression de ces entretoises au cours de laquelle elles se déforment plastiquement en dissipant une grande quantité d'énergie.In a preferred embodiment of the invention, the second cover rests on the first cover by tubular spacers embedded by their ends in each of the covers. These spacers constitute side shock absorbers because, for some of them, those located "behind" the terminal in the direction of the shock, the shock tending to bend the terminal causes a compression deformation of these spacers during which they deform plastically by dissipating a large amount of energy.

L'attelage des deux couvercles l'un au-dessus de l'autre et sur le corps de borne est réalisé de préférence par le moyen de tirants logés à l'intérieur des entretoises.The coupling of the two covers one above the other and on the terminal body is preferably made by means of tie rods housed inside the spacers.

D'autres caractéristiques et avantages de l'invention apparaítront de la description donnée ci-après d'un exemple de réalisation.Other characteristics and advantages of the invention will appear from the description given below of a example of realization.

Il sera fait référence au dessin annexe qui est un schéma partiel en coupe d'une borne conforme à l'invention,Reference will be made to the accompanying drawing which is a partial diagram in section of a terminal in accordance with the invention,

A la figure, le dispositif est représenté comportant un corps enterré 1 sous forme par exemple d'un caisson sensiblement parallélépipédique qui contient des éléments de guidage intérieurs 2 pour une borne cylindrique 3 montée coulissante de manière connue dans le corps 1. Le corps 1 est équipé d'un premier couvercle 4 reposant par des pieds cylindriques creux 5 sur des oreilles intérieures 6 du corps 1 disposées par exemple dans chacun de ses angles.In the figure, the device is shown comprising a buried body 1 in the form for example of a box substantially parallelepipedic which contains elements internal guide 2 for a cylindrical terminal 3 mounted sliding in known manner in the body 1. The body 1 is equipped with a first cover 4 resting on feet hollow cylindrical 5 on inner ears 6 of the body 1 arranged for example in each of its angles.

Chacun des pieds est pourvu d'un orifice cylindrique de passage d'un tirant 7 de fixation du couvercle 4 au corps 1. En partie supérieure, cet orifice comporte un lamage 8 destiné à accueillir soit la tête du tirant 7, lorsque n'est mis en oeuvre qu'un couvercle, soit une entretoise tubulaire 9 lorsque le couvercle 4 est surmonté d'un second couvercle 10. A son extrémité inférieure, chaque pied est également pourvu d'un lamage 11 pour, le cas échéant, accueillir et centrer une entretoise tubulaire. Au centre, le couvercle 4 comporte une chemise tubulaire 12 de diamètre intérieur égal au diamètre extérieur de la borne 3 de manière que celle-ci puisse y coulisser avec un minimum de jeu afin qu'elle y soit maintenue comme si elle était encastrée dans le couvercle. En partie supérieure, cette chemise comporte une portion d'entrée 13 de diamètre intérieur élargi par rapport au diamètre de la borne de manière à pouvoir accueillir la partie inférieure d'une chemise tubulaire identique appartenant à un couvercle supérieur. Cet emboítement permet d'offrir à la borne une longueur de maintien plus importante dans le corps de borne et donc une capacité de résistance à l'arrachement sous l'effet d'un choc latéral augmentée dans une borne comportant deux couvercles au lieu d'un.Each leg has a cylindrical hole passage of a tie rod 7 for fixing the cover 4 to the body 1. In the upper part, this orifice has a counterbore 8 intended to accommodate either the head of the tie rod 7, when only a cover is used, i.e. a tubular spacer 9 when the cover 4 is surmounted a second cover 10. At its lower end, each foot is also provided with a counterbore 11 for, the if necessary, accommodate and center a tubular spacer. In the center, the cover 4 has a tubular jacket 12 of inside diameter equal to outside diameter of terminal 3 so that it can slide there with a minimum of play so that it is kept there as if it was embedded in the cover. In part upper, this shirt has an inlet portion 13 inner diameter enlarged compared to the diameter of the terminal so that it can accommodate the lower part an identical tubular jacket belonging to a cover superior. This nesting allows to offer the terminal a longer holding length in the body of terminal and therefore a tear resistance capacity under the effect of an increased lateral shock in a terminal with two covers instead of one.

Le second couvercle 10 est de structure identique a celle du couvercle 4, avec des pieds 5, un orifice de passage de tirant débouchant dans des lamages supérieur 8 et inférieur 11 et une chemise centrale 12. Dans l'exemple représenté, les pieds 5 reposent directement sur les oreilles 6 du corps de borne. Ce n'est pas sortir du cadre de l'invention que de prévoir également un lamage dans chaque oreille 6 pour accueillir une entretoise tubulaire intercalée entre chaque pied et chaque oreille, la longueur de cette entretoise étant suffisante pour que les pieds soient écartés des oreilles de fixation.The second cover 10 is of identical structure to that of the cover 4, with feet 5, an orifice passage of tie rod opening into upper counterbores 8 and lower 11 and a central folder 12. In the example shown, the feet 5 rest directly on the ears 6 of the terminal body. It's not going out of the frame of the invention than to also provide a counterbore in each ear 6 to accommodate a tubular spacer inserted between each foot and each ear, the length of this spacer being sufficient for the feet are moved away from the mounting ears.

Lors d'un choc subi par la borne en position de service, les tirants "au choc" sont sollicités en traction tandis que les tirants "sous le choc" ou plus exactement les entretoises "sous le choc" 9 sont sollicitées en compression. Ces entretoises ont des dimensions qui ont été calculées pour se déformer plastiquement sous une compression donnée, si bien qu'elles constituent une sorte de fusible qui absorbe une grande quantité d'énergie sous une très faible course. Cette déformation peut suffire pour dissiper toute l'énergie engendrée par le choc; on a ainsi préservé les autres organes de la borne d'une déformation qui aurait demandé leur remplacement.In the event of an impact to the terminal in the position service, the “impact” tie rods are stressed in tension while the tie rods "in shock" or more exactly the “shock” spacers 9 are stressed in compression. These spacers have dimensions that have been calculated to deform plastically under compression given so much so that they constitute a kind of fuse that absorbs a large amount of energy under a very short stroke. This deformation may be sufficient for dissipate all the energy generated by the shock; so we have preserved the other terminal organs from deformation who would have asked for their replacement.

L'exemple ci-dessus décrit concerne deux couvercles superposés. Ce n'est pas sortir du cadre de l'invention que de prévoir plus de deux couvercles superposés.The example described above concerns two covers superimposed. It is not going beyond the scope of the invention than providing more than two overlapping covers.
