Description

La présente invention concerne un dispositif de potelet escamotable dans le sol et plus particulièrement de potelets de voiries.The present invention relates to a retractable post device in the ground and more particularly road posts.

Il existe déjà dans l'art antérieur des dispositifs de bornes télescopiques escamotables dans le sol permettant de commander à distance l'ouverture ou la fermeture d'un passage ou d'un emplacement. Ce type de dispositif fonctionne à l'aide de moyens de commande constitués par exemple par un vérin pneumatique à simple effet dont le cylindre est relié par un conduit d'alimentation à une source d'un fluide sous pression.There already exist in the prior art devices of telescopic bollards retractable into the ground making it possible to remotely control the opening or closing of a passage or a location. This type of device operates using control means constituted for example by a single-acting pneumatic cylinder, the cylinder of which is connected by a supply duct to a source of a pressurized fluid.

Ce type de dispositif présente l'inconvénient d'être de mise en oeuvre assez complexe puisqu'il nécessite la mise en place de vérins et l'utilisation d'un organe de commande à distance comme par exemple, un émetteur radio.This type of device has the disadvantage of being quite complex to implement since it requires the installation of jacks and the use of a remote control member such as, for example, a radio transmitter.

Le but de l'invention est de remédier à cet inconvénient en proposant un dispositif de structure très simple, fonctionnant uniquement à l'aide de moyens mécaniques simples, l'intervention des moyens de commande à distance étant remplacée par la simple intervention humaine.The object of the invention is to remedy this drawback by proposing a device of very simple structure, operating only using simple mechanical means, the intervention of the remote control means being replaced by simple human intervention.

A cet effet, le dispositif de potelet escamotable selon l'invention comprend un potelet constitué par un corps et un pied, situé en regard de l'extrémité ouverte supérieure d'un manchon cylindrique et creux, et est muni de moyens de verrouillage permettant de déplacer le potelet entre une position de service dans laquelle ledit corps de potelet s'étend au-­dessus du niveau de l'extrémité ouverte supérieure du manchon, et une position de repos dans laquelle ledit corps s'étend par son sommet sensiblement au niveau de l'extrémité supérieure ouverte dudit manchon, ce dispositif de potelet escamotable étant caractérisé en ce que lesdits moyens de verrouillage, comprenant une targette actionnée à l'aide d'une clef engagée dans une serrure, sont disposés dans un réceptacle entourant le pourtour supérieur du manchon cylindrique et creux, ladite targette coopérant en position de service dudit corps de potelet, d'une part avec une fenêtre ménagée le long du pourtour supérieur dudit manchon, et d'autre part, avec une cavité délimitée par deux collerettes en saillie entourant la partie supérieure dudit pied de potelet.To this end, the retractable post device according to the invention comprises a post constituted by a body and a foot, located opposite the upper open end of a cylindrical and hollow sleeve, and is provided with locking means allowing moving the post between a service position in which said post body extends above the level of the upper open end of the sleeve, and a rest position in which said body extends by its top substantially at the level of the open upper end of said sleeve, this retractable post device being characterized in that said locking means, comprising a bolt actuated by means of a key engaged in a lock, are arranged in a receptacle surrounding the upper periphery of the cylindrical and hollow sleeve, said bolt cooperating in the service position of said post body, on the one hand with a window formed along the periphery upper of said sleeve, and on the other hand, with a cavity delimited by two projecting flanges surrounding the upper part of said post foot.

Grâce à ce dispositif, le potelet est verrouillé lorsqu'il est en position de service et est facilement déverrouillable par simple mouvement de la targette libérant le pied du potelet, ledit potelet pouvant alors coulisser à l'intérieur du manchon cylindrique et creux scellé dans le sol.Thanks to this device, the post is locked when it is in the service position and is easily unlockable by simple movement of the bolt releasing the post foot, said post can then slide inside the cylindrical and hollow sleeve sealed in the ground.

Selon un mode préféré de réalisation de l'invention, le réceptacle comportant les moyens de verrouillage est également muni de moyens de renfort du pourtour supérieur du manchon, scellé dans le sol, de manière à protéger celui-ci en cas de choc violent du potelet en position de service. De cette manière, l'endommagement de ce dispositif de potelet escamotable selon l'invention, par exemple, par un véhicule, est alors facilement réparé par la mise en place d'un nouveau potelet tandis que le manchon scellé dans le sol et muni du réceptacle, peut être réutilisé tel quel.According to a preferred embodiment of the invention, the receptacle comprising the locking means is also provided with reinforcing means of the upper periphery of the sleeve, sealed in the ground, so as to protect the latter in the event of a violent impact from the post in the service position. In this way, the damage to this retractable post device according to the invention, for example, by a vehicle, is then easily repaired by the installation of a new post while the sleeve sealed in the ground and provided with the receptacle, can be reused as is.

D'autres avantages et réalisations de l'invention ressortiront de la description qui va suivre et en se référant aux dessins annexés, montrant, à titre d'exemple un mode de réalisation préféré du dispositif selon l'invention. Sur ces dessins :

  • - la figure 3 est une vue en coupe longitudinale du sommet du corps de potelet selon l'invention dans un deuxième mode de réalisation.
Other advantages and embodiments of the invention will emerge from the description which follows and with reference to the appended drawings, showing, by way of example, a preferred embodiment of the device according to the invention. In these drawings:
  • - Figure 1 is a longitudinal sectional view of the device according to the invention, the retractable post being in the service position;
  • - Figure 2 is a top view at the receptacle of the installation according to the invention;
  • - Figure 3 is a longitudinal sectional view of the top of the post body according to the invention in a second embodiment.

Le dispositif escamotable selon l'invention tel que représenté à la figure 1, comporte un potelet (1) constitué par un corps (2) et une pied (3), situé en regard de l'extrémité ouverte supérieure d'un manchon (4) cylindrique et creux, ce dispositif selon l'invention étant muni de moyens verrouillables (5) permettant de déplacer le corps de potelet (2) entre une position de service dans laquelle ledit corps de potelet (2) s'étend au-dessus du niveau de l'extrémité ouverte supérieure du manchon (4) et une position de repos dans laquelle ledit corps (2) s'étend par son sommet sensiblement au niveau de l'extrémité supérieure ouverte du manchon (4).The retractable device according to the invention as shown in Figure 1, comprises a post (1) constituted by a body (2) and a foot (3), located opposite the upper open end of a sleeve (4 ) cylindrical and hollow, this device according to the invention being provided with locking means (5) making it possible to move the post body (2) between a service position in which said post body (2) extends above the level of the upper open end of the sleeve (4) and a rest position in which said body (2) extends by its apex substantially at the level of the upper open end of the sleeve (4).

De façon plus précise, le dispositif selon l'invention, présente des moyens de verrouillage (5) comprenant une targette (6) actionnée à l'aide d'une clef (7) engagée dans une serrure (8), cesdits moyens de verrouillage (5) étant disposés dans un réceptacle (9) entourant le pourtour supérieur (10) du manchon (4), ladite targette (6) coopérant en position de service dudit corps de poteau (2), d'une part avec une fenêtre (11) ménagée le long du pourtour supérieur (10) du manchon (4) et d'autre part, avec une cavité (12) délimitée par deux collerettes (13) en saillie entourant la partie supérieure dudit pied de potelet (3).More specifically, the device according to the invention has locking means (5) comprising a bolt (6) actuated by means of a key (7) engaged in a lock (8), said locking means (5) being arranged in a receptacle (9) surrounding the upper periphery (10) of the sleeve (4), said bolt (6) cooperating in the service position of said post body (2), on the one hand with a window ( 11) formed along the upper periphery (10) of the sleeve (4) and on the other hand, with a cavity (12) delimited by two projecting flanges (13) surrounding the upper part of said post foot (3).

Comme on le voit sur la figure 1, le potelet (1) étant en position de service, la targette (6) pénètre à la fois dans ladite fenêtre (11) et dans ladite cavité (12) dont la largeur est sensiblement supérieure à l'épaisseur de ladite targette (6). De cette manière, le potelet est parfaitement verrouillé en position de service.As seen in Figure 1, the post (1) being in position service, the bolt (6) penetrates both into said window (11) and into said cavity (12) whose width is substantially greater than the thickness of said targette (6). In this way, the post is perfectly locked in the service position.

De plus, le pourtour inférieur du pied de potelet (3) comporte avantageusement une collerette d'appui (14) afin de reposer au fond du manchon (4) lorsque le potelet (1) se trouve en position de repos, c'est-­à-dire à l'intérieur dudit manchon (4).In addition, the lower periphery of the post base (3) advantageously comprises a support flange (14) in order to rest at the bottom of the sleeve (4) when the post (1) is in the rest position, that is to say ie inside said sleeve (4).

De façon plus précise, comme représenté sur la figure 2, le réceptacle (9) destiné à recevoir lesdits moyens de verrouillage (5), constitués par la targette (6) actionnée à l'aide d'une clef (7) engagée dans la serrure (8), est de forme quelconque préférentiellement carrée et comporte à chacun de ses angles, un élément carré (15) destiné à recevoir les vis de maintien du couvercle du réceptacle (9). Lors de la mise en place du dispositif selon l'invention, seul le couvercle dudit réceptacle (9) muni des orifices de passage du corps du potelet (2) et de la serrure (8), est visible de l'extérieur, ledit manchon (4) cylindrique et creux étant scellé dans le sol ainsi que le réceptacle (9).More precisely, as shown in FIG. 2, the receptacle (9) intended to receive said locking means (5), constituted by the bolt (6) actuated by means of a key (7) engaged in the lock (8), is of any preferentially square shape and comprises at each of its angles, a square element (15) intended to receive the screws for holding the cover of the receptacle (9). When the device according to the invention is put in place, only the cover of said receptacle (9) provided with holes for the passage of the post body (2) and the lock (8), is visible from the outside, said sleeve (4) cylindrical and hollow being sealed in the ground as well as the receptacle (9).

Dans un mode préféré de réalisation de l'invention, le couvercle du réceptacle (9) est légèrement incliné sur la chaussée et dépasse dudit réceptacle (9) afin de permettre l'écoulement des eaux de ruissellement.In a preferred embodiment of the invention, the cover of the receptacle (9) is slightly inclined on the roadway and protrudes from said receptacle (9) in order to allow the flow of runoff water.

De même, pour éviter la stagnation d'eaux superficielles sur le couvercle du réceptacle (9), celui-ci est avantageusement réalisé en pointes de diamant.Similarly, to avoid stagnation of surface water on the cover of the receptacle (9), the latter is advantageously made of diamond points.

Comme on l'a vu précédemment, le corps du potelet (2) est susceptible de subir des chocs assez violents lorsqu' il se trouve en position de service. Par conséquent, dans un mode préféré de réalisation de l'invention, le réceptacle (9) comprend des moyens de renfort (16) constitués par un fer plat (17) qui entoure complétement le pourtour supérieur (10) du manchon (4), et comporte une ouverture en regard de la fenêtre (11) pour laisser passer la targette (6), cedit fer plat (17) étant raccordé aux quatre éléments carrés (15) dudit réceptacle (9) par quatre languettes plates (18) délimitant ainsi trois compartiments (19) jouant également le rôle de renfort une fois rempli de béton, le quatrième compartiment comportant lesdits moyens de verrouillage (5).As we have seen previously, the post body (2) is liable to undergo fairly violent shocks when it is in the service position. Consequently, in a preferred embodiment of the invention, the receptacle (9) comprises reinforcing means (16) constituted by a flat iron (17) which completely surrounds the upper periphery (10) of the sleeve (4), and has an opening opposite the window (11) to let through the bolt (6), said flat iron (17) being connected to the four square elements (15) of said receptacle (9) by four flat tabs (18) thus delimiting three compartments (19) also playing the role of reinforcement once filled with concrete, the fourth compartment comprising said locking means (5).

Enfin, le fonctionnement du dispositif selon l'invention, nécessite le soulèvement du corps de poteau (2) lorsque celui-ci est en position de repos pour amener ce corps en position de service, la cavité (12)étant alors en regard de la fenêtre (11) de manière à permettre le passage de ladite targette (6).Finally, the operation of the device according to the invention requires the lifting of the post body (2) when the latter is in the rest position to bring this body into the operating position, the cavity (12) being then opposite the window (11) so as to allow the passage of said bolt (6).

Dans un premier mode de réalisation de l'invention tel que représenté sur la figure 1, le soulèvement dudit corps de potelet (2) est réalisé à l'aide de la clef (7). En effet, ladite clef (7) comporte un manche (20) dont l'extrémité libre présente la forme d'un "T" coopérant avec un orifice (21), situé au sommet dudit corps de poteau (2). De cette manière, on soulève le corps de potelet (2) avec ladite clef (7), puis on maintient le corps (2) d'une main tandis que la clef (7) actionne la targette (6). Ce premier mode de réalisation présente l'inconvénient de devoir maintenir le corps (2) sans moyen de préhension particulier, tandis que la clef (7) actionne la serrure (8).In a first embodiment of the invention as shown in Figure 1, the lifting of said post body (2) is carried out using the key (7). Indeed, said key (7) has a handle (20) whose free end has the shape of a "T" cooperating with an orifice (21), located at the top of said post body (2). In this way, the post body (2) is lifted with said key (7), then the body (2) is held with one hand while the key (7) actuates the bolt (6). This first embodiment has the drawback of having to hold the body (2) without any particular gripping means, while the key (7) actuates the lock (8).

Afin de remédier à cet inconvénient, dans un deuxième mode de réalisation du soulèvement du corps de potelet (2) tel que représenté sur la figure (3), le sommet du corps de potelet (2) comporte alors un orifice (21) prolongé par un fourreau (22) permettant le passage d'une poignée coulissante (23) dont la course est limitée par un écrou (24)venant buter sur le pourtour inférieur dudit fourreau (22).In order to remedy this drawback, in a second embodiment of the lifting of the post body (2) as shown in FIG. (3), the top of the post body (2) then comprises an orifice (21) extended by a sheath (22) allowing the passage of a sliding handle (23) whose stroke is limited by a nut (24) abutting on the lower periphery of said sheath (22).

De cette manière, l'utilisateur peut à la fois soulever le corps de poteau (2) par ladite poignée coulissante (23) tandis qu'il possède une main libre pour actionner ladite targette (6) à l'aide de la clef (7).In this way, the user can both lift the post body (2) by said sliding handle (23) while he has a free hand to actuate said bolt (6) using the key (7 ).

Dans une variante de réalisation du soulèvement du corps de potelet (2) selon la figure 3, on peut envisager le logement de ladite poignée coulissante (23) dans une cavité ménagée au sommet du corps de potelet (2) de manière à ce qu'en position de repos, la poignée coulissante (23) ne soit pas visible de l'extérieur.In an alternative embodiment of the lifting of the post body (2) according to FIG. 3, one can envisage the housing of said sliding handle (23) in a cavity formed at the top of the post body (2) so that in the rest position, the sliding handle (23) is not visible from the outside.

En effet, selon ce mode de réalisation du corps de potelet (2) selon la figure 3, le dispositif selon l'invention est utilisé et fonctionne de la manière suivante :In fact, according to this embodiment of the post body (2) according to FIG. 3, the device according to the invention is used and operates in the following manner:

Le réceptacle (9) et le manchon (4) cylindrique et creux étant scellés dans le sol, seul le couvercle dudit réceptacle (9) muni de deux orifices, à savoir, un en regard de l'extrémité ouverte supérieure dudit manchon (4) et le second en regard de la serrure (8) des moyens de verrouillage (5), étant visible, l'utilisateur descend le potelet (1) à l'intérieur du manchon cylindrique et creux (4). Le potelet (1) est alors en position de repos et il suffit à l'utilisateur de soulever le corps du potelet (2) par l'intermédiaire de la poignée coulissante (23) jusqu'à ce que la cavité (12) soit en regard de la fenêtre (11) du pourtour supérieur du manchon (4), puis d'actionner la targette (6) à l'aide d'une clef (7) afin que cette dite targette (6) pénètre dans la cavité (12) à travers la fenêtre (11). Le dispositif selon l'invention est alors en position de service et il suffit d'effectuer la manoeuvre inverse en tournant la clef (7) afin que la targette (6) soit en position d'ouverture, pour que la cavité (12) soit libérée de manière à permettre le coulissement du potelet (1) dans le manchon (4), en position de repos.The receptacle (9) and the cylindrical and hollow sleeve (4) being sealed in the ground, only the cover of said receptacle (9) provided with two orifices, namely, one facing the upper open end of said sleeve (4) and the second facing the lock (8) of the locking means (5), being visible, the user lowers the post (1) inside the cylindrical and hollow sleeve (4). The post (1) is then in the rest position and the user need only lift the body of the post (2) by means of the sliding handle (23) until the cavity (12) is opposite the window (11) of the upper periphery of the sleeve (4), then actuate the bolt (6) using a key (7) so that this so-called bolt (6 ) enters the cavity (12) through the window (11). The device according to the invention is then in the service position and it suffices to carry out the reverse maneuver by turning the key (7) so that the bolt (6) is in the open position, so that the cavity (12) is released so as to allow the post (1) to slide in the sleeve (4), in the rest position.
