Description

OBSTACLE EVENTUELLEMENT ESCAMOTABLE DANS LE SOL.OBSTACLE POSSIBLY REMOVABLE IN THE SOIL.

L'invention se rapporte à un obstacle éventuellement escamotable notamment dans le sol.  The invention relates to a possibly retractable obstacle, particularly in the ground.

Pour contrôler ou interdire l'accès des véhicules à certains lieux, il est connu de placer sur le chemin d'accès à ce lieu un obstacle interdisant le passage des véhicules. Pour interdire l'accès, il suffit de fixer au sol une borne fixe dont le pied est ancré dans un massif en béton.  To control or prohibit the access of vehicles to certain places, it is known to place on the path to this place an obstacle prohibiting the passage of vehicles. To prevent access, it is sufficient to fix on the ground a fixed terminal whose foot is anchored in a concrete block.

Pour permettre cependant l'accès à certains lieux, l'obstacle doit être escamotable.  However, to allow access to certain places, the obstacle must be retractable.

Il existe des barrières qui barrent transversalement le passage à contrôler et qui peuvent être relevées par pivotement autour d'un axe pour laisser passer les véhicules. Il s'agit souvent de barrières pour l'accès à des parkings. L'obstacle est souvent en matériau plastique.  There are barriers that crossbar the passage to control and can be raised by pivoting around an axis to let the vehicles. These are often barriers to access to car parks. The obstacle is often made of plastic material.

On a conçu d'autres obstacles qui sont, cette fois ci, escamotables dans le sol.  Other obstacles have been conceived which are, this time, retractable into the ground.

Ces obstacles se présentent généralement comme un cylindre en acier ou en aluminium faisant saillie au dessus du sol et venant se loger dans une enveloppe enterrée.  These obstacles are generally like a cylinder steel or aluminum projecting above the ground and being housed in a buried envelope.

Un mécanisme sert à faire monter et descendre le cylindre. Ce mécanisme comprend un moteur qui peut être électrique, hydraulique ou pneumatique cependant la 20 manoeuvre de la borne pourrait être manuelle.  A mechanism is used to raise and lower the cylinder. This mechanism includes a motor which can be electric, hydraulic or pneumatic however the operation of the terminal could be manual.

Il comprend également des moyens de guidage de la partie cylindrique venant au dessus du sol.  It also comprises means for guiding the cylindrical portion coming above the ground.

Ce type d'obstacle enterré est souvent de faible hauteur.  This type of buried obstacle is often of low height.

Il est alors moins visible et il arrive fréquemment que ces obstacles soient heurtés par des véhicules.  It is then less visible and it often happens that these obstacles are struck by vehicles.

Il arrive parfois que le choc soit si important qu'il provoque la rupture de la partie cylindrique située au dessus du sol.  It sometimes happens that the shock is so important that it causes the rupture of the cylindrical part situated above the ground.

Cette situation pose problème notamment sur un sol en pente.  This situation is problematic especially on sloping ground.

En effet, du fait de sa forme cylindrique, cette partie arrachée roule sur le sol et 30 pourrait provoquer des accidents voire blesser quelqu'un.  Indeed, because of its cylindrical shape, this torn part rolls on the ground and 30 could cause accidents or even hurt someone.

Un autre problème important est que cette partie arrachée soit projetée plus ou moins loin lors de l'impact.  Another important problem is that this part torn off is projected more or less far during the impact.

L'invention a pour but d'apporter une solution aux problèmes évoqués ci avant.  The invention aims to provide a solution to the problems mentioned above.

A cet effet, l'invention a pour objet, un obstacle éventuellement escamotable dans le sol comprenant une fixation avec le sol et une partie visible formant obstacle, cet obstacle étant caractérisé en ce qu'un lien souple relie la partie visible au moins indirectement au sol, ce lien ayant une longueur supérieure à la distance séparant les deux points d'attaches dudit lien.  For this purpose, the object of the invention is an obstacle that can be retracted into the ground, which comprises an attachment with the ground and a visible part forming an obstacle, this obstacle being characterized in that a flexible link connects the visible part at least indirectly to the ground, this link having a length greater than the distance separating the two points of attachment of said link.

L'invention sera bien comprise à l'aide de la description ci-après faite à titre 10 d'exemple non limitatif en regard du dessin qui représente: FIG 1: une coupe verticale de l'obstacle en position interdisant le passage FIG 2: une coupe verticale de l'obstacle après un accident.  The invention will be better understood from the following description given by way of nonlimiting example with reference to the drawing which represents: FIG. 1: a vertical section of the obstacle in position preventing the passage FIG. a vertical section of the obstacle after an accident.

FIG 3: une coupe verticale d'un obstacle fixe.  FIG 3: a vertical section of a fixed obstacle.

FIG 4: Vue partielle en coupe verticale d'une borne escamotable.  FIG 4: Partial view in vertical section of a retractable terminal.

En se reportant au dessin, on voit une borne 1 destinée à interdire l'accès d'un lieu à un véhicule.  Referring to the drawing, there is a terminal 1 for prohibiting access of a place to a vehicle.

Cette borne 1 fixe est ancrée dans le sol par une fixation.  This fixed terminal 1 is anchored in the ground by a fixing.

Par exemple, elle comprend une embase 2 logée dans le sol et une partie visible 3 formant obstacle.  For example, it comprises a base 2 housed in the ground and a visible part 3 forming an obstacle.

Cette embase 2 est ancrée, par exemple dans un massif en béton ou est constituée par ce massif en béton. Sur cette embase est fixée la partie visible.  This base 2 is anchored, for example in a concrete block or is constituted by the concrete base. On this base is fixed the visible part.

Pour permettre l'accès à un lieu, on fait cette fois ci appel à un obstacle 1 ( Figure 1 et Figure 2) qui est escamotable dans le sol.  To allow access to a place, this time it uses an obstacle 1 (Figure 1 and Figure 2) that is retractable into the ground.

Cet obstacle escamotable comprend une enveloppe logée dans le sol dans laquelle coulisse ledit obstacle.  This retractable obstacle comprises an envelope housed in the ground in which slides said obstacle.

Cette enveloppe ancrée dans le sol a des dimensions au moins suffisantes pour loger toute la hauteur de l'obstacle afin qu'en position escamotée, le haut de l'obstacle soit sensiblement à la rase du sol.  This envelope anchored in the ground has dimensions at least sufficient to accommodate the entire height of the obstacle so that in the retracted position, the top of the obstacle is substantially at the level of the ground.

Cette enveloppe forme l'embase 2 pour la partie visible qui constitue l'obstacle.  This envelope forms the base 2 for the visible part which constitutes the obstacle.

Un mécanisme 4 logé au moins partiellement dans l'enveloppe permet le déplacement de l'obstacle.  A mechanism 4 housed at least partially in the envelope allows the displacement of the obstacle.

Cet obstacle est bien évidemment solidaire du mécanisme et ne peut être détaché que volontairement ou par rupture d'une liaison existant entre l'obstacle et le mécanisme. Ce mécanisme comprend un châssis fixé dans l'enveloppe, des moyens de guidage en translation de l'obstacle et généralement un moyen moteur pour déplacer l'obstacle.  This obstacle is obviously integral with the mechanism and can be detached only voluntarily or by breaking an existing link between the obstacle and the mechanism. This mechanism comprises a frame fixed in the casing, guide means in translation of the obstacle and generally a motor means for moving the obstacle.

Une alimentation en énergie est prévue pour ce moteur.  A power supply is provided for this engine.

Un dispositif 5 de commande tel un ensemble émetteur/récepteur commande le déplacement de l'obstacle.  A control device such as a transmitter / receiver assembly controls the movement of the obstacle.

Selon l'invention, un lien 6 souple relie au moins indirectement le sol ou l'embase 2 à la partie visible 3, ce lien 6 ayant une longueur supérieure à la distance séparant les 10 deux points d'attache 7,8 dudit lien.  According to the invention, a flexible link 6 at least indirectly connects the ground or the base 2 to the visible portion 3, this link 6 having a length greater than the distance between the two attachment points 7,8 of said link.

Ainsi, si un choc avec l'obstacle provoque la désolidarisation de la partie visible avec le châssis ou l'enveloppe ou l'embase ou un autre point d'ancrage dans le sol, cette partie visible formant l'obstacle est encore retenue par le lien.  Thus, if an impact with the obstacle causes the visible part to separate from the chassis or the envelope or the base or another anchoring point in the ground, this visible part forming the obstacle is still retained by the link.

Par exemple, le lien est fixé sur le chariot 9 mobile portant la partie visible de la borne 15 escamotable et sur la partie visible.  For example, the link is fixed on the mobile carriage 9 carrying the visible part of the retractable terminal 15 and on the visible part.

Ce chariot est déplacé verticalement par un moyen moteur et il est guidé en translation sur des guides présenté par un châssis.  This carriage is moved vertically by a motor means and is guided in translation on guides presented by a frame.

Du fait que le lien soit plus long que la distance entre les deux points d'attache, l'énergie du choc est en premier dissipée dans les moyens de liaison entre la partie 20 visible et l'embase et le lien ne subit que le résiduel de l'énergie.  Since the link is longer than the distance between the two attachment points, the energy of the shock is first dissipated in the connection means between the visible part and the base and the link undergoes only the residual Energy.

Ce lien 6 est, par exemple, conformé en spirale afin de mieux se positionner dans la partie creuse de la borne lors de la montée ou descente lorsqu'il s'agit d'une borne escamotable dans le sol.  This link 6 is, for example, shaped spiral to better position itself in the hollow portion of the terminal when climbing or descending when it is a retractable terminal in the ground.

Le lien va éventuellement absorbé le reste de l'énergie et empêcher que l'obstacle de 25 trop s'éloigner de son emplacement initial.  The link will eventually absorb the rest of the energy and prevent the obstacle from getting too far from its original location.

On peut utiliser un câble métallique ou une chaîne ou un moyen équivalent.  A wire rope or chain or equivalent means may be used.

Il est prévu sur la face interne de l'obstacle qui est généralement creux, un point d'attache du lien obtenu lors de la fabrication de l'obstacle.  It is provided on the inner face of the obstacle which is generally hollow, a point of attachment of the link obtained during the manufacture of the obstacle.

Un tel élément apporte une sécurité supplémentaire et évite les accidents induits par la 30 projection de la partie visible lors d'un choc provoquant la rupture de la borne.  Such an element provides additional security and avoids the accidents caused by the projection of the visible part during an impact causing the breakage of the terminal.
