The spikes have two active positions (8, 8') which are substantially symmetrical relative to the vertical plane containing the shaft (6). <IMAGE>

Description

L'invention concerne un barrage escamotable destiné à constituer, par exemple, un dispositif anti-intrusion pour véhicules terrestres.The invention relates to a retractable barrier intended to constitute, for example, an anti-intrusion device for land vehicles.

Il est connu de barrer des routes ou des voies d'accès au moyen de barrières ou de herses. Les herses munies de pointes sont de véritables défenses destinées à arrêter, en le détériorant, tout véhicule qui tenterait un passage forcé.It is known to block roads or access routes by means of barriers or harrows. Harrows fitted with spikes are real defenses intended to stop, by damaging it, any vehicle that attempts a forced passage.

De nombreux système transportables ont été imaginés tels que frises, poutres à pointes etc. Toutefois, lorsqu'il s'agit de pouvoir barrer à volonté une voie d'accès, soit de manière régulière, soit en cas de nécessité urgente, il est évidemment souhaitable de prévoir un dispositif permanent, mais escamotable.Many transportable systems have been imagined such as friezes, spiked beams, etc. However, when it comes to being able to block an access route at will, either regularly, or in case of urgent need, it is obviously desirable to provide a permanent, but retractable device.

Certains systèmes de ce dernier type ont été envisagés, mais ils ne sont généralement pas ou pas complètement encastrés dans le sol et/ou nécessitent un travail important et onéreux d'implantation. Dans les brevets BE-A-900018 et GB-2032983, par exemple, les dispositifs décrits ne sont pas du tout encastrés (hors sol). Dans les brevets DE-3540739, DE-A-3134247, US- 4,101,235 et US-1,563,637, par exemple, il s'agit de structures métalliques qui doivent venir se loger ou se monter dans une fosse aménagée. En outre, ces systèmes ne sont généralement pas réversibles (fonctionnement unilatéral) et ne comportent pas de motorisation (voir les brevets allemands précités) ou comportent une motorisation non incorporée et complètement à l'écart (voir brevets US précités). De plus, ce dernier type de systèmes, une fois en place, est complètement fixe et ne permet pas d'être éventuellement récupéré en vue d'être déplacé.Some systems of the latter type have been envisaged, but they are generally not or not completely embedded in the ground and / or require significant and expensive installation work. In patents BE-A-900018 and GB-2032983, for example, the devices described are not at all embedded (above ground). In the patents DE-3540739, DE-A-3134247, US-4,101,235 and US-1,563,637, for example, these are metallic structures which must be housed or mounted in a fitted pit. In addition, these systems are generally not reversible (one-sided operation) and do not include a motorization (see the aforementioned German patents) or include an unincorporated motorization and completely separate (see above-mentioned US patents). In addition, this latter type of system, once in place, is completely fixed and does not allow it to be possibly recovered with a view to being moved.

Pour palier ces inconvénients, les inventeurs proposent un barrage escamotable, de conception simple, qui ne nécessite qu'un terrassement minimum. En outre, sa mise en service est rapide et il est récupérable.To overcome these drawbacks, the inventors propose a retractable dam, of simple design, which requires only minimum earthwork. In addition, it is quick to put into service and is recoverable.

Le barrage selon l'invention est remarquable en ce qu'il comporte une coquille monobloc destinée à venir se loger complètement dans une fouille du sol, prévue à cet effet, tandis que dans ladite coquille, est aménagée une barrière escamotable de façon à posséder une position de repos en dessous du niveau du sol, et à pouvoir faire saillie hors du niveau du sol au moyen d'une motorisation incorporée, qui est commandée ou télécommandée par au moins un dispositif d'actionnement manuel et/ou automatique. Il est entendu que le mot fouille est, selon l'invention, une simple excavation, sans travail particulier du Génie Civil, comme le réclame souvent les dispositifs connus, qui ne sont pas prêts à la pose et/ou qui nécessitent des travaux d'implantation.The dam according to the invention is remarkable in that it comprises a one-piece shell intended to come to be completely housed in a ground excavation, provided for this purpose, while that in said shell, a retractable barrier is arranged so as to have a rest position below ground level, and to be able to protrude out of ground level by means of an incorporated motorization, which is controlled or remotely controlled by at minus a manual and / or automatic actuation device. It is understood that the word excavation is, according to the invention, a simple excavation, without any particular work of Civil Engineering, as often claimed by known devices, which are not ready for installation and / or which require work of implantation.

La coquille peut être formée par emboutissage d'une tôle, mais avantageusement, elle est formée par un bloc de béton en forme générale d'auge, qui est préfabriqué en usine (de même que son aménagement intérieur), sa mise en place ultérieurement dans la fouille étant particulièrement simplifiée.The shell can be formed by stamping a sheet, but advantageously, it is formed by a concrete block in the general shape of a trough, which is prefabricated in the factory (as well as its interior layout), its installation later in the search being particularly simplified.

La barrière peut être quelconque, sous forme de grille ou autrement. Toutefois, l'invention est plus particulièrement destinée à constituer un dispositif anti-intrusion de sécurité et comporte, à cet effet, une herse escamotable. Selon un mode de réalisation, la barrière escamotable comporte un arbre tournant muni d'une pluralité de pointes disposées de manière sensiblement perpendiculaire audit arbre, de façon à pouvoir faire saillie hors du sol ou s'escamoter selon la position angulaire de l'arbre, tandis qu'une grille de roulement recouvre la coquille, la structure de ladite grille étant prévue pour laisser passer à volonté lesdites pointes. Avantageusement, chaque pointe se présente sous la forme d'un cylindre dont l'extrémité libre est munie d'au moins un biseau, tandis que ladite pointe est fixée sur l'arbre, de manière démontable, son autre extrémité traversant ledit arbre diamétralement.The barrier can be any, in the form of a grid or otherwise. However, the invention is more particularly intended to constitute a security anti-intrusion device and comprises, for this purpose, a retractable harrow. According to one embodiment, the retractable barrier comprises a rotating shaft provided with a plurality of spikes arranged substantially perpendicular to said shaft, so as to be able to project out of the ground or retract according to the angular position of the tree, while a rolling grid covers the shell, the structure of said grid being designed to allow said spikes to pass at will. Advantageously, each point is in the form of a cylinder, the free end of which is provided with at least one bevel, while said point is fixed on the shaft, in a removable manner, its other end passing through said shaft diametrically.

De Préférence, l'extrémité de la pointe présente, sur une partie au moins de sa longueur, une rainure longitudinale selon une génératrice du cylindre constituant ladite pointe de manière à former un évent pour favoriser en cas de besoin le dégonflage des pneumatiques d'un véhicule.Preferably, the end of the tip has, over at least part of its length, a longitudinal groove along a generatrix of the cylinder constituting said tip so as to form a vent to favor, if necessary, the deflation of the tires of a vehicle.

Selon un mode de réalisation, les pointes sont régulièrement réparties le long de l'arbre et de façon sensiblement parallèles entre elles, tandis que ledit arbre et les pointes possèdent au moins une première position d'action qui est sensiblement symétrique, par rapport à la verticale, d'une autre position que lesdites pointes occupent, soit après avoir été forcées en rotation à partir de la première position d'action, soit volontairement pour constituer une autre position d'action inverse de la première. En outre, l'arbre est par exemple maintenu dans la coquille au moyen de paliers tandis qu'il est mû en rotation par au moins un motoréducteur frein associé à un limiteur de couple et une transmission à chaîne ou courroie.According to one embodiment, the tips are regularly distributed along the tree and substantially parallel to each other, while said tree and the points have at least a first position of action which is substantially symmetrical, with respect to the vertical, from another position than said points occupy, either after having been forced into rotation from the first position of action, or voluntarily to constitute another position of action opposite to the first. In addition, the shaft is for example held in the shell by means of bearings while it is rotated by at least one brake gear motor associated with a torque limiter and a chain or belt transmission.

La coquille disposée ainsi dans le sol doit être capable d'évacuer les eaux pluviales, mais elle peut même constituer un véritable caniveau d'évacuation en étant aménagée au bas d'une zone en déclivité. A cet effet, la coquille présente un fond en pente dans son sens longitudinal et/ou transversal et des orifices en partie basse pour l'évacuation des eaux pluviales éventuelles.The shell thus placed in the ground must be able to evacuate rainwater, but it can even constitute a real evacuation channel by being fitted at the bottom of a declining area. To this end, the shell has a sloping bottom in its longitudinal and / or transverse direction and orifices in the lower part for the evacuation of any rainwater.

Le dispositif selon l'invention se présente donc comme un ensemble monobloc prêt à la pose, avec une préparation du sol tout à fait simplifiée, ce qui n'était pas le cas jusqu'à présent. Un tel dispositif est entièrement préfabriqué, monté et précablé en usine, de telle sorte qu'après sa mise en place dans le sol, il n'y a plus qu'à effectuer les branchements et raccordements nécessaires.The device according to the invention therefore presents itself as a one-piece assembly ready for installation, with completely simplified soil preparation, which was not the case until now. Such a device is entirely prefabricated, assembled and pre-wired in the factory, so that after it has been placed in the ground, all that is required is to make the necessary connections and connections.

L'invention sera bien comprise et d'autres particularités apparaîtront à la lecture de la description qui va suivre et qui se rapporte aux dessins annexés dans lesquels:

  • - la figure 1 est une coupe en vue transversale d'un dispositif selon l'invention, mis en place dans une fouille,
  • - la figure 2 est une vue en coupe longitudinale du dispositif de la figure 1,
  • - la figure 3 est une vue en plan du dispositif des figures 1 et 2;
  • - la figure 4 est une vue en élévation et partiellement en coupe d'une pointe fixée sur son arbre.
The invention will be clearly understood and other particularities will appear on reading the description which follows and which relates to the appended drawings in which:
  • FIG. 1 is a cross-section through a device according to the invention, placed in a dig,
  • FIG. 2 is a view in longitudinal section of the device in FIG. 1,
  • - Figure 3 is a plan view of the device of Figures 1 and 2;
  • - Figure 4 is an elevational view partially in section of a tip fixed on its shaft.

Le dispositif selon l'invention comporte une coquille 1 (figures 1 à 3), ici en béton compacte fabriqué en usine.The device according to the invention comprises a shell 1 (Figures 1 to 3), here in compact concrete made in the factory.

Cette coquille présente une forme sensiblement d'auge avec un contour extérieur sensiblement trapézoïdal (figure 1). La coquille 1 présente en outre un fond 2 en pente (figure 2) de manière à permettre, comme déjà dit, l'évacuation éventuelle d'eaux pluviales, suivant, bien sûr, le lieu d'implantation du dispositif.This shell has a substantially trough shape with a substantially trapezoidal outer contour (Figure 1). The shell 1 also has a sloping bottom 2 (Figure 2) so as to allow, as already said, the possible evacuation of rainwater, depending, of course, on the location of the device.

Pour permettre cette évacuation des eaux, la coquille, qui peut constituer un véritable caniveau, comporte à cet effet, dans sa partie basse, des orifices 17.To allow this evacuation of water, the shell, which can constitute a real gutter, has for this purpose, in its lower part, orifices 17.

La coquille 1 est destinée à venir se loger dans une fouille 3, qui comporte, de manière classique, par exemple, une feuille d'étanchéité, un lit de "tout venant" 4 et un lit de "grave laitier" 5 (figure 1), le reste de la fouille étant évidemment destiné à être comblé, une fois le dispositif mis en place.The shell 1 is intended to be housed in an excavation 3, which comprises, in a conventional manner, for example, a sealing sheet, a bed of "all comers" 4 and a bed of "grave slag" 5 (FIG. 1 ), the rest of the excavation is obviously intended to be filled, once the device is in place.

Dans la coquille 1, est aménagé un arbre 6 (figures 1 et 2) disposé dans le sens longitudinal de ladite coquille. L'arbre 6 est supporté par des paliers tels que 7 (figure 2).In the shell 1, a shaft 6 (Figures 1 and 2) is arranged arranged in the longitudinal direction of the said shell. The shaft 6 is supported by bearings such as 7 (Figure 2).

L'arbre 6 est pourvu d'une pluralité de pointes 8 (figures 2 et 4) constituant ainsi une herse.The shaft 6 is provided with a plurality of points 8 (Figures 2 and 4) thus constituting a harrow.

L'arbre 6 peut être mis en rotation par une motorisation, comme un motoréducteur frein 9 (figures 1 et 2) dénommé ci-après motoréducteur. Le motoréducteur 9, disposé, comme montré, dans la coquille 1, est relié à l'arbre 6, au moyen d'une transmission qui comporte, par exemple, une chaîne ou une courroie 10 et un limiteur de couple 18.The shaft 6 can be rotated by a motor, such as a brake gear motor 9 (Figures 1 and 2) hereinafter referred to as a gear motor. The geared motor 9, arranged, as shown, in the shell 1, is connected to the shaft 6, by means of a transmission which comprises, for example, a chain or a belt 10 and a torque limiter 18.

Il est bien sûr possible d'utiliser à la place du motoréducteur, par exemple, un vérin électro-mécanique ou hydraulique aménagé de manière à entraîner l'arbre 6 en rotation.It is of course possible to use in place of the geared motor, for example, an electro-mechanical or hydraulic cylinder arranged so as to drive the shaft 6 in rotation.

La coquille 1 est couverte sur le dessus par une grille de roulement 11 (figures 2 et 3), qui repose sur un épaulement périphérique ménagé à cet effet sur le bord supérieur de ladite coquille.The shell 1 is covered on top by a rolling grid 11 (Figures 2 and 3), which rests on a peripheral shoulder formed for this purpose on the upper edge of said shell.

Chaque pointe 8 est, par exemple, du type de celle représentée plus en détail sur la figure 4. Ici la pointe 8 est formée par un cylindre biseauté à son extrémité libre, tandis qu'elle est fixée de manière démontable sur l'arbre 6 (représenté ici en traits interrompus). Comme le montre la figure 4, la pointe traverse diamétralement l'arbre 6 et se fixe au moyen d'un boulon 12 et d'une goupille 13 ou similaire.Each point 8 is, for example, of the type shown in more detail in FIG. 4. Here the point 8 is formed by a beveled cylinder at its free end, while it is detachably fixed on the shaft 6 (shown here in dashed lines). As shown in Figure 4, the tip diametrically passes through the shaft 6 and is fixed by means of a bolt 12 and a pin 13 or the like.

En outre, comme le montre aussi cette figure 4, l'extrémité libre de la pointe présente une rainure longitudinale 14 sur une partie de sa longueur. La rainure 14, de préférence à bords francs, accentue les effets de pointe et constitue un véritable évent, qui accélère le dégonflage des pneumatiques en cas de besoin.In addition, as also shown in this Figure 4, the free end of the tip has a longitudinal groove 14 over part of its length. The groove 14, preferably with straight edges, accentuates the peak effects and constitutes a real vent, which accelerates the deflation of the tires when necessary.

Comme le montre de plus la figure 2, les points 8 sont disposées de manière sensiblement parallèles entre elles de façon à présenter au moins une position escamotée 8′ (représentée en pointillé sur la figure 1, position dans laquelle les pointes au repos recouvrent le motoréducteur 9), une position d'action 8 (les pointes étant tournées dans le sens opposé au sens d'avancement à interdire) et une position extrême 8˝ (représentée aussi en pointillé sur la figure 1) dans laquelle chaque pointe repose sur le bord supérieur de la coquille 1.As further shown in Figure 2, the points 8 are arranged substantially parallel to each other so as to have at least one retracted position 8 '(shown in dotted lines in Figure 1, position in which the points at rest cover the gearmotor 9), an action position 8 (the points being turned in the opposite direction to the direction of advance to be prohibited) and an extreme position 8˝ (also shown in dotted lines in FIG. 1) in which each point rests on the edge upper shell 1.

Il est clair que les positions 8 et 8′ sont obtenues au moyen du motoréducteur 9 qui entraîne l'arbre 6 en rotation. Par contre, la position 8˝ est celle occupée par les pointes, soit après avoir été forcées en rotation à partir de la position 8, soit après rotation complémentaire et volontaire de l'arbre 6 par le motoréducteur 9 lorsque l'on désire interdire la circulation dans l'autre sens, (par exemple, pour interdire la sortie d'un véhicule auquel on vient d'autoriser l'entrée).It is clear that positions 8 and 8 ′ are obtained by means of the geared motor 9 which drives the shaft 6 in rotation. On the other hand, the position 8˝ is that occupied by the tips, either after having been forced into rotation from position 8, or after complementary and voluntary rotation of the shaft 6 by the geared motor 9 when it is desired to prohibit the traffic in the other direction, (for example, to prohibit the exit of a vehicle which has just been authorized to enter).

Sur les dessins, on peut constater en outre des éléments de fin de course 15 (figure 2), des éléments étanches d'éclairage 16 (figure 2), un orifice d'entrée 19 pour les câbles de raccordement destinés à la connexion électrique d'une ou plusieurs boîtes de raccordement, telle la boîte 20 (figure 2), pour le circuit de puissance et le circuit de commande de la motorisation et des divers éléments électriques, ...In the drawings, it can also be seen end-of-travel elements 15 (FIG. 2), waterproof lighting elements 16 (FIG. 2), an inlet orifice 19 for the connection cables intended for the electrical connection of one or more connection boxes, such as the box 20 (FIG. 2), for the power circuit and the control circuit motorization and various electrical elements, ...

Naturellement la grille 11 présente une structure qui permet le passage aisé des pointes 8.Naturally, the grid 11 has a structure which allows the points 8 to pass easily.

Enfin, le motoréducteur 9 peut, bien sûr, être commandé ou télécommandé manuellement ou automatiquement par tout système convenable, optique, électronique, radio etc., un système entièrement manuel, à levier par exemple, étant par ailleurs éventuellement prévu.Finally, the gear motor 9 can, of course, be controlled or remotely controlled manually or automatically by any suitable system, optical, electronic, radio, etc., a fully manual system, for example with a lever, being also possibly provided.

La description qui précède montre bien la facilité de mise en place du dispositif qui se présente comme un ensemble prêt à la pose et qui est en outre récupérable (la figure 3 montre, sur la périphérie de la coquille 1, des points d'ancrage pour la manutention de cette dernière ou de l'ensemble du dispositif).The above description clearly shows the ease of installation of the device which is presented as an assembly ready for installation and which is also recoverable (FIG. 3 shows, on the periphery of the shell 1, anchoring points for handling of the latter or of the entire device).
