Description

L'invention concerne un dispositif anti-franchissement pour élément de clôture. L'invention concerne aussi un élément de clôture comprenant un tel dispositif anti-franchissement. Elle trouve application dans le domaine des clôtures.The invention relates to an anti-crossing device for a fence element. The invention also relates to a fence element comprising such an anti-crossing device. It finds application in the field of fences.

Le document US-4,667,935 décrit un assemblage de différents éléments destinés à réaliser des éléments de clôture. En particulier, les éléments de clôture sont composés des barres verticales reliées entre elles par des barres de maintien horizontales et assemblées de manière à ce que les barres verticales dépassent au dessus des barres de maintien. Des éléments de protection sont emmanchés sur les extrémités des barres verticales qui dépassent. Les éléments de protection sont constitués d'une base percée d'un trou borgne qui permet à la base de s'emmancher sur les extrémités des barres verticales. La fixation des éléments de protection est ensuite réalisée par des vis.US-4,667,935 describes an assembly of different elements for making fence elements. In particular, the fence elements are composed of vertical bars interconnected by horizontal holding bars and assembled so that the vertical bars protrude above the holding bars. Protection elements are fitted on the ends of the vertical bars protruding. The protection elements consist of a base pierced with a blind hole which allows the base to slip on the ends of the vertical bars. The fixing of the protection elements is then carried out by screws.

L'alignement de chaque élément de protection par rapport à l'élément de clôture sur lequel il est monté, est réalisé par l'ajustement entre les dimensions du trou et les dimensions des extrémités des barres verticales et par le serrage de la vis et en particulier par la mise en butée du fond du trou sur le sommet de l'extrémité de la barre verticale.The alignment of each protection element with respect to the fence element on which it is mounted, is achieved by adjusting between the dimensions of the hole and the dimensions of the ends of the vertical bars and by tightening the screw and particular by the abutment of the bottom of the hole on the top of the end of the vertical bar.

Si le trou est trop grand par rapport à la barre verticale, l'élément de protection pourra se trouver désaxé par rapport à la barre verticale et les différents éléments de protection formeront un ensemble disgracieux. L'alignement des éléments de protection entre eux et par rapport à l'élément de clôture n'est donc pas garanti.If the hole is too large in relation to the vertical bar, the protection element may be off-center with respect to the vertical bar and the various protection elements will form an unsightly assembly. The alignment of the protective elements with each other and with the closure element is therefore not guaranteed.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels:

  • la Fig. 1 représente une vue d'un élément de clôture comprenant un dispositif anti-franchissement selon l'invention;
  • la Fig. 2 représente un dispositif anti-franchissement selon une première variante;
  • la Fig. 3 représente un dispositif anti-franchissement selon une deuxième variante;
  • la Fig. 4 représente un dispositif anti-franchissement selon une troisième variante.
The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being given in relation to the attached drawings, among which:
  • FIG. 1 represents a view of a fence element comprising an anti-crossing device according to the invention;
  • FIG. 2 represents an anti-crossing device according to a first variant;
  • FIG. 3 represents an anti-crossing device according to a second variant;
  • FIG. 4 shows an anti-crossing device according to a third variant.

La Fig. 1 représente un élément de clôture 102 constitué de barres verticales 112 et de barres horizontales 110 qui relient les barres verticales 112 entre-elles. Les barres verticales 112 sont emmanchées dans les barres horizontales 110 de manière à les traverser, laissant ainsi dépasser les extrémités 104 des barres verticales 112.Fig. 1 represents a fence element 102 consisting of vertical bars 112 and horizontal bars 110 which connect the vertical bars 112 to each other. The vertical bars 112 are fitted into the horizontal bars 110 so as to pass through, thus leaving the ends 104 of the vertical bars 112.

Les extrémités des barres verticales 112 qui dépassent forment ainsi des picots 104 de forme générale cylindrique qui font saillie par rapport à la barre horizontale 110 qui les relie.The ends of the vertical bars 112 which protrude thus form pins 104 of generally cylindrical shape which project relative to the horizontal bar 110 which connects them.

L'élément de clôture 102 peut être un panneau fixe ou un panneau mobile du type portail.The closure element 102 may be a fixed panel or a movable panel of the portal type.

L'élément de clôture 102 peut être aussi un poteau de clôture sur lequel viennent se fixer des panneaux de clôture.The fence element 102 may also be a fence post on which fence panels are attached.

L'élément de clôture 102 peut aussi être un bavolet.The fence element 102 may also be a flap.

Sur les picots 104 sont agencés des dispositifs anti-franchissement 100 qui peuvent être placé sur chaque picot 104 ou certains de ces picots 104.On the pins 104 are arranged anti-crossing devices 100 which can be placed on each pin 104 or some of these pins 104.

Les dispositifs anti-franchissement 100 sont ainsi disposés sur la partie supérieure de l'élément de clôture 102 pour dissuader les personnes non autorisées d'escalader l'élément de clôture 102 pour pénétrer à l'intérieur de l'espace clos.The anti-crossing devices 100 are thus disposed on the upper part of the fence element 102 to deter unauthorized persons from climbing the fence element 102 to penetrate inside the enclosed space.

Chaque dispositif anti-franchissement 100 comprend un moyen de fixation 106 qui permet la fixation du dispositif anti-franchissement 100 sur l'élément de clôture 102 avec lequel il est prévu pour coopérer. Chaque dispositif anti-franchissement 100 comprend aussi au moins une lame 108 solidaire du moyen de fixation 106.Each anti-crossing device 100 comprises a fixing means 106 which allows the fixing of the anti-crossing device 100 on the closing element 102 with which it is intended to cooperate. Each anti-crossing device 100 also comprises at least one blade 108 integral with the fixing means 106.

Le moyen de fixation 106 est constitué d'une base 208 percée d'un trou 202 qui est destiné à permettre l'emmanchement selon une direction X1 de la base 208 sur un premier élément de l'élément de clôture 102, en l'occurrence l'un des picots 104. Pour maintenir le dispositif anti-franchissement 100 sur le premier élément 104, des moyens de maintien 204 (Fig. 2) sont agencés à l'intérieur du trou 202.The fixing means 106 consists of a base 208 pierced with a hole 202 which is intended to allow the fitting in a direction X1 of the base 208 on a first element of the closing element 102, in this case one of the pins 104. To maintain the anti-crossing device 100 on the first element 104, holding means 204 (FIG 2) are arranged inside the hole 202.

Pour permettre la venue en butée de la base 208 sur un deuxième élément de l'élément de clôture 102, en l'occurrence l'une des barres horizontales 110, le trou 202 est débouchant. La mise en butée de chaque base 208 sur le deuxième élément 110, c'est-à-dire un élément commun, permet d'aligner tous les dispositifs anti-franchissement 100 entre eux avant que ceux-ci soient définitivement mis en position par les moyens de maintien 204 et donc de réaliser un assemblage esthétique.To allow the abutment of the base 208 on a second element of the closing element 102, in this case one of the horizontal bars 110, the hole 202 is open. The abutment of each base 208 on the second element 110, that is to say a common element, makes it possible to align all the anti-crossing devices 100 with each other before they are definitively put into position by the holding means 204 and thus to achieve an aesthetic assembly.

La base 208 est dans l'exemple constituée d'une rondelle plate dont la face inférieure vient en butée sur la barre horizontale 110.The base 208 is in the example consisting of a flat washer whose lower face abuts on the horizontal bar 110.

Les moyens de maintien sont constitués de doigts flexibles 204 séparés par des espaces 206 et qui sont issus de la base 208 et dirigés vers l'intérieur du trou débouchant 202. Les doigts 204 peuvent ainsi enserrer les picots 104 et assurer le blocage du dispositif anti-franchissement 100 sans mise en place d'éléments de fixation complémentaire. Selon la flexibilité des doigts 204 et le diamètre du trou 202, les dispositifs anti-franchissement 100 pourront s'adapter à des picots 104 de dimensions variables. Un dispositif anti-franchissement 100 pourra donc être monté sur des picots de dimensions différentes. La flexibilité des doigts est assurée par leurs dimensions, en particulier par leur épaisseur et par le matériau les constituant. Le dimensionnement des doigts 204 par rapport aux picots 104 sera tel que le démontage des dispositifs anti-franchissement 100 sera excessivement difficile voire impossible sans que les dispositifs anti-franchissement 100 soient détruits.The holding means consist of flexible fingers 204 separated by spaces 206 and which come from the base 208 and directed towards the inside of the opening hole 202. The fingers 204 can thus grip the pins 104 and ensure the locking of the anti-rotation device. -franchissement 100 without setting up additional fastening elements. Depending on the flexibility of the fingers 204 and the diameter of the hole 202, the anti-crossing devices 100 will be able to adapt to pins 104 of variable dimensions. An anti-crossing device 100 may therefore be mounted on pins of different dimensions. The flexibility of the fingers is ensured by their dimensions, in particular by their thickness and by the material constituting them. The sizing of the fingers 204 with respect to the pins 104 will be such that the disassembly of the anti-crossing devices 100 will be excessively difficult if not impossible without the anti-crossing devices 100 being destroyed.

Le dispositif anti-franchissement 100 peut être en métal ou en plastique ou en tout matériau suffisamment rigide, il peut être constitué d'un ou plusieurs de ces matériaux.The anti-crossing device 100 may be made of metal or plastic or any sufficiently rigid material, it may consist of one or more of these materials.

Dans le cas où les picots 104 sont verticaux et pointent vers le haut, les dispositifs anti-franchissement 100 sont emmanchés selon une direction d'emmanchement X1 verticale dirigée vers le bas. Pour faciliter l'emmanchement du dispositif anti-franchissement 100 sur les picots 104, les doigts 204 sont montants en direction du centre du trou débouchant 202 dans une direction opposée à la direction d'emmanchement X1. Dans l'exemple, les doigts 204 pointent donc vers le haut. Cette disposition facilite l'écartement des doigts 204 sous l'action du picot 104 lors de l'emmanchement. En outre, cette disposition empêche aussi l'enlèvement des dispositifs anti-franchissement 100, en effet, les doigts 204 se resserrent d'autant plus sur les picots 104, que la force d'extraction dirigée vers le haut est forte.In the case where the pins 104 are vertical and point upwards, the anti-crossing devices 100 are fitted in one direction vertical X1 fitting downwards. To facilitate the fitting of the anti-crossing device 100 on the pins 104, the fingers 204 are upright towards the center of the through hole 202 in a direction opposite to the fitting direction X1. In the example, the fingers 204 are pointing upwards. This arrangement facilitates the spacing of the fingers 204 under the action of the pin 104 during fitting. In addition, this arrangement also prevents the removal of anti-crossing devices 100, in fact, the fingers 204 are tightened even more on the pins 104, the pulling force directed upwards is strong.

La Fig. 2 représente un dispositif anti-franchissement 100 selon un premier mode de réalisation et la Fig. 3 représente un dispositif anti-franchissement 100 selon un deuxième mode de réalisation.Fig. 2 shows an anti-crossing device 100 according to a first embodiment and FIG. 3 represents an anti-crossing device 100 according to a second embodiment.

Les dispositifs anti-franchissement 100 comprennent une pluralité de lames 108 sous forme de triangle dont l'un des côtés est solidaire de la base 208 et dont l'angle opposé pointe dans une direction sensiblement opposée à la direction d'emmanchement X1. Dans l'exemple, les lames 108 peuvent être verticales ou présenter un angle compris entre 0 et 20 degrés avec la verticale.The anti-crossing devices 100 comprise a plurality of blades 108 in the form of a triangle whose one side is secured to the base 208 and whose opposite angle points in a direction substantially opposite to the fitting direction X1. In the example, the blades 108 may be vertical or have an angle between 0 and 20 degrees with the vertical.

Préférentiellement les lames 108 sont régulièrement réparties autour de la base 208. Dans le premier mode de réalisation, les lames 108 sont au nombre de deux et diamétralement opposées. Dans le deuxième mode de réalisation, les lames 108 sont au nombre de trois et réparties régulièrement selon des angles de 120°. Le nombre de lames 108 n'est limité que par l'espace disponible autour de la base 208 et leur disposition autour de la base 208 peut être spécifique selon l'esthétisme ou l'encombrement disponible autour de l'élément de clôture 102.Preferably the blades 108 are evenly distributed around the base 208. In the first embodiment, the blades 108 are two in number and diametrically opposed. In the second embodiment, the blades 108 are three in number and evenly distributed at angles of 120 °. The number of blades 108 is limited only by the space available around the base 208 and their arrangement around the base 208 may be specific according to the aesthetics or the space available around the fence element 102.

La Fig. 4 représente un troisième mode de réalisation du dispositif anti-franchissement. Le dispositif anti-franchissement 400 est constitué d'un moyen de fixation 406 qui vient se positionner sur l'élément de clôture 102. Le dispositif anti-franchissement 400 comprend une pluralité de lames 408 solidaire du moyen de fixation 406, qui est constitué d'une base 410 percée d'une pluralité de trous 402, ici deux, destinés à permettre l'emmanchement de la base 410 sur la pluralité de picots 104 qui sont en regard des trous 402. A l'intérieur de ces trous sont agencés des moyens de maintien 404 destinés à maintenir le dispositif anti-franchissement 400 sur les picots 104. Les trous 402 sont débouchants pour permettre la venue en butée de la base 410 sur les barres horizontales 110.Fig. 4 shows a third embodiment of the anti-crossing device. The anti-crossing device 400 consists of a fixing means 406 which is positioned on the closing element 102. The anti-crossing device 400 comprises a plurality of blades 408 secured to the fastening means 406, which consists of a base 410 pierced with a plurality of holes 402, here two, intended to allow the fitting of the base 410 on the plurality of pins 104 which are opposite the holes 402. Inside these holes are arranged holding means 404 for holding the anti-crossing device 400 on the pins 104. The holes 402 open to allow the abutment of the base 410 on the horizontal bars 110.

Dans l'exemple de la Fig. 4, le dispositif anti-franchissement 400 a la forme d'une barrette en U dont les extrémités des branches dirigées vers le haut forment les lames 408.In the example of FIG. 4, the anti-crossing device 400 has the shape of a U-shaped bar whose ends of the branches directed upwards form the blades 408.

Le nombre de trous 402 ne correspond pas forcément au nombre de picots en regard, dans ce cas les trous 402 qui permettent la fixation du dispositif anti-franchissement 400 sont répartis sur la longueur de la base 410 et pour permettre l' insertion des picots 104 intermédiaires situés entre deux trous 402, des orifices 412 sont réalisés dans la base 410. Ces orifices permettent ainsi le passage des picots 104 qui ne sont pas en vis-à-vis de trous de fixation 402.The number of holes 402 does not necessarily correspond to the number of pins opposite, in this case the holes 402 which allow the fixing of the anti-crossing device 400 are distributed over the length of the base 410 and to allow the insertion of the pins 104 intermediates located between two holes 402, orifices 412 are formed in the base 410. These orifices thus allow the passage of the pins 104 which are not vis-a-vis the fixing holes 402.

De manière similaire aux modes de réalisation précédents, les moyens de maintien 404 sont constitués de doigts flexibles montants et les lames 408 sont réparties le long de la base 410.Similar to the previous embodiments, the holding means 404 consist of flexible upright fingers and the blades 408 are distributed along the base 410.

Une pluralité de dispositifs anti-franchissement peut être emmanchée les uns sur les autres. Le premier dispositif anti-franchissement placé sur l'élément de clôture 102 vient en butée sur le deuxième élément 110 et le dispositif suivant vient alors en butée sur le premier dispositif anti-franchissement et ainsi de suite.A plurality of anti-crossing devices can be fitted onto each other. The first anti-crossing device placed on the closing element 102 abuts the second element 110 and the next device then abuts on the first anti-crossing device and so on.

Bien entendu, la présente invention n'est pas limitée aux exemples et modes de réalisation décrits et représentés, mais elle est susceptible de nombreuses variantes accessibles à l'homme de l'art.Of course, the present invention is not limited to the examples and embodiments described and shown, but it is capable of many variants accessible to those skilled in the art.

Par exemple, l'élément de clôture 102 a été représenté comme étant constitué de barres verticales 112 et de barres horizontales 110, mais ces barres peuvent prendre toutes les orientations compatibles avec l'esthétisme de la clôture et avec le mode de fabrication de l'élément de clôture 102, en particulier, l'un ou les deux barres 110, 112 peuvent être agencées de manière oblique.For example, the fence element 102 has been shown to consist of vertical bars 112 and horizontal bars 110, but these bars can take all the orientations compatible with the aesthetics of the fence and with the method of manufacture of the fence. fence element 102, in particular, one or both bars 110, 112 may be arranged obliquely.

De manière identique, les picots sur lesquels les dispositifs anti-franchissement viennent se positionner sont verticaux et dirigés vers le haut, mais ils peuvent prendre toutes les orientations possibles selon les applications désirées.Similarly, the pins on which the anti-crossing devices are positioned are vertical and directed upwards, but they can take all possible orientations depending on the desired applications.

Les barres 110, 112 constituant l'élément de clôture 102 peuvent être pleines ou creuses et de section quelconque, en particulier la section peut être circulaire, rectangulaire, losange ou autres. De la même manière, les picots 104 ont une forme générale de cylindre, de parallélogramme ou autre.The bars 110, 112 constituting the closing element 102 may be solid or hollow and of any cross-section, in particular the section may be circular, rectangular, rhombic or other. In the same way, the pins 104 have a general shape of cylinder, parallelogram or other.

Par exemple, les lames 108 ont une forme de triangle, mais elles peuvent prendre toute forme adéquate, comme par exemple une couronne constituée d'une pluralité de pointes ou un élément décoratif ou une combinaison constituée d'un élément décoratif et d'un élément sécuritaire. Dans ce dernier cas, l'élément décoratif sera avantageusement placé du côté intérieur de l'espace à protéger et l'élément sécuritaire sera placé du côté extérieur de l'espace à protéger, de l'intérieur de l'espace à protéger, l'élément décoratif cachera l'élément sécuritaire.For example, the blades 108 have a triangle shape, but they can take any suitable shape, such as for example a crown consisting of a plurality of points or a decorative element or a combination consisting of a decorative element and a safe element. In the latter case, the decorative element will advantageously be placed on the inside of the space to be protected and the security element will be placed on the outside of the space to be protected, from the inside of the space to be protected. decorative element will hide the security element.

Les lames 108 ont été présentées comme ayant un angle compris entre 0 et 20 degrés avec la verticale, mais elles peuvent avoir une direction quelconque comprise entre 0 degré et 180 degrés par rapport à la direction d'emmanchement, permettant ainsi de diriger les lames 108 en direction des intrus potentiels.The blades 108 have been shown to have an angle between 0 and 20 degrees to the vertical, but they can have any direction between 0 degrees and 180 degrees relative to the direction of fitting, thus allowing the blades 108 to be directed. towards potential intruders.

Les premiers éléments 104 sont constitués par les prolongements des barres verticales 112 qui dépassent des barres horizontales, mais ces premiers éléments peuvent être des picots fixés sur les barres horizontales.The first elements 104 are constituted by the extensions of the vertical bars 112 which protrude from the horizontal bars, but these first elements may be pins fixed on the horizontal bars.

Les deuxièmes éléments 110 sont constitués des barres horizontales, mais ces deuxièmes éléments peuvent être constitués par des épaulements réalisés sur les premiers éléments 104 et sur lesquels les bases 208 viennent en butée.The second elements 110 consist of horizontal bars, but these second elements may consist of shoulders made on the first elements 104 and on which the bases 208 abut.

La base 208 a été représentée comme étant constituée d'une rondelle plate de faible épaisseur, mais elle peut être constitué d'une portion de cylindre et les moyens de maintien 204 peuvent alors être constitués d'une ou plusieurs vis.The base 208 has been shown to consist of a flat washer of small thickness, but it may consist of a cylinder portion and the holding means 204 may then consist of one or more screws.
