Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne une structure de clôture formée d'éléments de clôture destinés à être assemblés sur place pour réaliser une séparation entre une première et une seconde parties d'un terrain, par exemple une séparation autour d'un terrain de sport entre le terrain lui-même et ses abords.The present invention relates to a fence structure formed of fence elements intended to be assembled on site to make a separation between a first and a second part of a field, for example a separation around a sports field between the field itself and its surroundings.

On connaît déjà des structures de clôture à éléments modulaires assemblés les uns aux autres autour de mini-stades polyvalents.There are already known fence structures with modular elements assembled to each other around versatile mini-stadiums.

Ces clôtures sont réalisées à base de montants scellés dans le sol entre lesquels sont fixées des parois en grillage.These fences are made from uprights sealed in the ground between which are fixed mesh walls.

Ces structures nécessitent de réaliser les scellements, ou même des fondations en attente dans le sol. Cela exclut ou rend difficiles les démontages saisonniers, les modifications pour adaptation de la taille, ou les déplacements de la clôture.These structures require sealing, or even foundations pending in the ground. This excludes or makes difficult seasonal disassembly, modifications to adapt the size, or moving the fence.

On connaît par ailleurs une structure de garde-corps pour toits de bâtiments, décrite dans le document US-A-5 188 342, dans laquelle le garde-corps est stabilisé par des traverses inférieures lestées chacune par un bloc proéminent. Un tel garde-corps, prévu pour une application particulière sur les toits de bâtiments, ne serait manifestement pas utilisable pour une clôture de terrain de sport, car il ne permettrait pas un accès aisé et sûr du public ou des joueurs jusqu'à la face de la clôture munie des traverses et des blocs proéminents.There is also known a railing structure for roofs of buildings, described in document US-A-5 188 342, in which the railing is stabilized by lower crosspieces weighted each with a prominent block. Such a railing, intended for a particular application on the roofs of buildings, would obviously not be usable for a fence of a sports field, because it would not allow easy and safe access of the public or the players to the face. of the fence fitted with prominent crosspieces and blocks.

On connaît également une barrière pour contenir les foules, décrite dans le document GB-A-2 228 510. La barrière est tenue par une plaque métallique horizontale reposant sur le sol le long du premier côté de la barrière, et par un cadre horizontal reposant sur le sol le long du second côté de la barrière à laquelle il est relié par des barres obliques de renfort. Une telle structure ne permet pas un accès aisé et sûr du public ou des joueurs jusqu'à la face de barrière munie du cadre horizontal et des barres obliques de renfort.A barrier is also known for containing crowds, described in document GB-A-2 228 510. The barrier is held by a horizontal metal plate resting on the ground along the first side of the barrier, and by a horizontal frame resting on the ground along the second side of the barrier to which it is connected by reinforcing slashes. Such a structure does not allow easy and safe access by the public or the players to the barrier face provided with the horizontal frame and the reinforcing slashes.

EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION

Le problème proposé par la présente invention est de concevoir une nouvelle structure de clôture qui puisse être aisément déplaçable, facilement transportable, et qui, pour cela, puisse être simplement posée sur le sol sans nécessiter de scellements ou de fondations, tout en présentant en elle-même une stabilité suffisante pour respecter les exigences de sécurité, et en particulier pour supporter les efforts de basculement appliqués sur la clôture tant par les intempéries que par les utilisateurs.The problem proposed by the present invention is to design a new fence structure which can be easily moved, easily transportable, and which, for this, can be simply placed on the ground without requiring seals or foundations, while presenting in it - even sufficient stability to respect the security requirements, and in particular to withstand the tilting forces applied to the fence both by the weather and by users.

Selon l'invention, la stabilité de la clôture doit être obtenue sans pour autant augmenter inutilement l'encombrement de la clôture elle-même, et en particulier sans diminuer l'espace utile du terrain de sport bordant un premier côté d'une telle clôture, et sans empêcher une libre circulation des utilisateurs de l'autre côté de la clôture.According to the invention, the stability of the fence must be obtained without unnecessarily increasing the size of the fence itself, and in particular without reducing the useful space of the sports field bordering a first side of such a fence. , and without preventing free movement of users across the fence.

Pour cela, l'idée qui est à la base de l'invention résulte de l'observation selon laquelle une clôture pour terrain de loisirs ou de sports sépare généralement deux portions de terrain, une première portion de terrain devant être utilisable pour la pratique des sports jusqu'au ras de la paroi verticale de clôture dans des conditions de sécurité satisfaisantes, la seconde partie de terrain devant pouvoir être utilisée pour le simple déplacement des spectateurs et autres utilisateurs jusqu'au ras de la paroi verticale de clôture. Les deux parties de terrain séparées par la clôture sont ainsi réservées à des usages différents.For this, the idea which is the basis of the invention results from the observation that a fence for recreational or sports grounds generally separates two portions of land, a first portion of land must be usable for the practice of sports close to the vertical fence wall in satisfactory safety conditions, the second part of the field must be able to be used for the simple movement of spectators and other users to the level of the vertical fence wall. The two parts of land separated by the fence are thus reserved for different uses.

Dans d'autres circonstances, on veut pouvoir utiliser les deux parties de terrain pour le déplacement des utilisateurs jusqu'au ras de la paroi verticale de clôture.In other circumstances, we want to be able to use the two parts of the ground for the movement of users up to the level of the vertical fence wall.

L'invention met à profit ces observations pour proposer une nouvelle structure de clôture permettant ces utilisations jusqu'au ras de la paroi verticale de clôture, tout en permettant une auto-stabilité suffisante sans scellements ni fondations.The invention takes advantage of these observations to propose a new fence structure allowing these uses up to the level of the vertical fence wall, while allowing sufficient self-stability without seals or foundations.

Ainsi, un élément de clôture selon l'invention destiné à être assemblé avec d'autres éléments similaires pour former une clôture entre une première et une seconde parties de terrain comprend :

  • une première partie rigide de structure, formant une paroi destinée à être dressée, par exemple verticalement, pour séparer la première et la seconde parties de terrain,
  • une seconde partie rigide de structure, solidaire de la première partie de structure et se développant selon un plan se raccordant angulairement à la base de la première partie de structure, ladite seconde partie rigide de structure étant destinée à reposer sur le sol,
  • au moins un élément amovible de lestage, destiné à venir en appui sur la seconde partie de structure reposant sur le sol, pour s'opposer au basculement de l'élément de clôture et pour lui conférer une auto-stabilité ;
  • la face supérieure des éléments amovibles de lestage des éléments de clôture successifs forme une surface généralement plane sur laquelle les utilisateurs peuvent circuler.
Thus, a fence element according to the invention intended to be assembled with other similar elements to form a fence between a first and a second piece of land comprises:
  • a first rigid structural part, forming a wall intended to be erected, for example vertically, to separate the first and second parts of the ground,
  • a second rigid structural part, integral with the first structural part and developing along a plane connecting angularly to the base of the first structural part, said second rigid structural part being intended to rest on the ground,
  • at least one removable ballasting element, intended to come to bear on the second part of the structure resting on the ground, to oppose the tilting of the fence element and to give it self-stability;
  • the upper face of the removable ballasting elements of the successive closing elements forms a generally flat surface on which the users can circulate.

Selon un premier mode de réalisation, la seconde partie rigide de structure se développe selon un demi-plan depuis la base de la première partie de structure. Ce mode de réalisation est approprié pour clore un terrain de sport : on dispose alors les éléments de clôture de façon que la seconde partie rigide de structure posée sur le sol soit orientée vers l'extérieur du terrain de sport, les spectateurs pouvant marcher sur la surface supérieure des éléments amovibles de lestage.According to a first embodiment, the second rigid structural part develops in a half-plane from the base of the first structural part. This embodiment is suitable for closing a sports field: the fence elements are then placed so that the second rigid structural part placed on the ground is oriented towards the outside of the sports field, spectators being able to walk on the upper surface of removable ballast elements.

Par contre, pour réaliser une aire de rencontre, ces mêmes éléments de clôture sont orientés de façon que la seconde partie rigide de structure posée sur le sol soit dirigée vers l'intérieur de l'aire de rencontre, la face supérieure des éléments amovibles de lestage constituant une surface plane rigide sur laquelle peuvent être posés des sièges dont le dossier peut être constitué par la paroi verticale de clôture.By cons, to achieve a meeting area, these same fence elements are oriented so that the second rigid structural part placed on the ground is directed towards the interior of the meeting area, the upper face of the removable elements of ballasting constituting a rigid flat surface on which seats can be placed, the back of which may consist of the vertical enclosure wall.

Une autre possibilité est de prévoir une seconde partie rigide de structure en deux zones s'étendant respectivement de part et d'autre de la base de la première partie de structure.Another possibility is to provide a second rigid part of the structure in two zones extending respectively on either side of the base of the first part of the structure.

Selon un mode de réalisation, l'élément de clôture selon l'invention est tel que :

  • la seconde partie de structure comprend un ou plusieurs cadres rigides formés d'un profilé périphérique comportant une aile verticale périphérique et une aile horizontale inférieure intérieure, les cadres étant solidarisés extérieurement à deux traverses,
  • le ou les éléments amovibles de lestage sont en appui sur l'aile horizontale du cadre et sont bordés par l'aile verticale du cadre,
  • les traverses sont solidarisées à deux montants respectifs entre lesquels sont fixés des panneaux.
According to one embodiment, the fence element according to the invention is such that:
  • the second part of the structure comprises one or more rigid frames formed by a peripheral profile comprising a peripheral vertical wing and an inner lower horizontal wing, the frames being secured externally to two crosspieces,
  • the removable ballasting element (s) are supported on the horizontal wing of the frame and are bordered by the vertical wing of the frame,
  • the crosspieces are secured to two respective uprights between which panels are fixed.

De préférence, les traverses présentent une section carrée, dimensionnée de façon que leurs faces supérieures soient sensiblement en affleurement de la face supérieure des éléments amovibles de lestage, de façon à constituer un trottoir ou zone de déambulation à surface supérieure régulière.Preferably, the sleepers have a square section, dimensioned so that their upper faces are substantially flush with the upper face of the removable ballast elements, so as to constitute a sidewalk or wandering area with regular upper surface.

De préférence, les montants sont des tubes métalliques à section ronde, bouchonnés à leur extrémité supérieure, soudés à leur extrémité inférieure sur la face supérieure de la traverse respective. Une telle section ronde favorise la sécurité, évitant que des utilisateurs viennent se blesser lors d'un choc contre la paroi verticale de clôture.Preferably, the uprights are metal tubes of round section, capped at their upper end, welded at their lower end to the upper face of the respective crosspiece. Such a round section promotes safety, preventing users from being injured in an impact against the vertical fence wall.

Les éléments amovibles de lestage 9 s'opposent au basculement de l'élément de clôture 1-3 pour lui conférer une auto-stabilité.Removable ballast elements 9 are placed in abutment on the second rigid part 7 of structure which itself rests on the ground. The removable ballasting elements 9 oppose the tilting of the closing element 1-3 to give it self-stability.

Les faces supérieures 10 des éléments amovibles de lestage 9 des éléments de clôture successifs forment une surface généralement plane sur laquelle les utilisateurs peuvent circuler.The upper faces 10 of the removable ballasting elements 9 of the successive closing elements form a generally flat surface on which the users can circulate.

Dans les modes de réalisation représentés, la seconde partie 7 de structure comprend un cadre rigide 11 formé d'un profilé périphérique comportant une aile verticale périphérique 12 et une aile horizontale inférieure 13 orientée vers l'intérieur du cadre. Le cadre rigide 11 présente par exemple un contour rectangulaire, et ses deux côtés transversaux 14 et 15 sont solidarisés extérieurement à deux traverses respectives 16 et 17.In the embodiments shown, the second structural part 7 comprises a rigid frame 11 formed of a peripheral profile comprising a vertical peripheral wing 12 and a lower horizontal wing 13 oriented towards the inside of the frame. The rigid frame 11 has for example a rectangular outline, and its two transverse sides 14 and 15 are secured externally to two respective crosspieces 16 and 17.

Les éléments amovibles de lestage 9 viennent s'encastrer dans le cadre 11, en appui sur l'aile horizontale 13 du cadre 11 et bordés par l'aile verticale 12 du cadre 11.The removable ballasting elements 9 are embedded in the frame 11, bearing on the horizontal wing 13 of the frame 11 and bordered by the vertical wing 12 of the frame 11.

Dans le mode de réalisation représenté sur les figures 1 à 3, plusieurs éléments amovibles de lestage, par exemple six éléments, de forme générale parallélépipédique plate, sont posés côte-à-côte pour remplir l'espace délimité par le cadre périphérique 11. Chaque élément amovible de lestage 9 a avantageusement un poids inférieur à la limite admissible pour un déplacement manuel, par exemple un poids inférieur à 80 kilogrammes.In the embodiment shown in FIGS. 1 to 3, several removable ballasting elements, for example six elements, of generally flat parallelepiped shape, are placed side by side to fill the space delimited by the peripheral frame 11. Each removable ballast element 9 advantageously has a weight less than the admissible limit for manual movement, for example a weight less than 80 kilograms.

Les éléments amovibles de lestage 9 sont réalisés par exemple en béton armé moulé, et peuvent être préfabriqués.The removable ballast elements 9 are made for example of molded reinforced concrete, and can be prefabricated.

Une autre solution consiste à couler sur place une plaque de béton dans le cadre 11 en prévoyant une plaque inférieure de coffrage. L'élément de lestage ainsi constitué peut être ultérieurement déplacé à l'aide d'une grue ou d'un autre engin de manutention.Another solution is to pour a concrete plate on site in the frame 11 by providing a lower formwork plate. The ballast element thus formed can be subsequently moved using a crane or another handling device.

Dans tous les cas, la masse des éléments de lestage 9 est choisie de façon à s'opposer à tout basculement de la clôture lorsqu'elle subit une sollicitation horizontale inférieure à une valeur de sollicitation déterminée, correspondant par exemple à la poussée de deux personnes, ou au poids de deux personnes accrochées à la première partie rigide 6 de structure.In all cases, the mass of the ballasting elements 9 is chosen so as to oppose any tilting of the fence when it is subjected to a horizontal stress lower than a determined stress value, corresponding for example to the thrust of two people , or the weight of two people attached to the first rigid part 6 of the structure.

Les traverses telles que les traverses 16 et 17 présentent de préférence une section carrée, et sont dimensionnées de façon que leur face supérieure telle que la face supérieure 18 de la traverse 17, soit sensiblement en affleurement de la face supérieure 10 des éléments amovibles de lestage 9 lorsque ceux-ci sont posés dans le cadre rigide 11.The crossmembers such as the crossmembers 16 and 17 preferably have a square section, and are dimensioned so that their upper face such as the upper face 18 of the crossmember 17 is substantially flush with the upper face 10 of the removable ballasting elements. 9 when these are placed in the rigid frame 11.

Les traverses 16 et 17 sont solidarisées à deux montants respectifs 19 et 20. Les montants 19 et 20 sont des tubes métalliques à section ronde, bouchonnés à leurs extrémités supérieures respectives 21 et 22, et soudés à leurs extrémités inférieures sur la face supérieure de la traverse respective 16 ou 17.The crosspieces 16 and 17 are secured to two respective uprights 19 and 20. The uprights 19 and 20 are metal tubes of round section, capped at their respective upper ends 21 and 22, and welded at their lower ends to the upper face of the respective crosspiece 16 or 17.

Le cadre rigide 11 est par exemple fixé aux traverses respectives 16 et 17 par boulonnage, le boulon traversant des trous respectifs représentés sur les figures. Des réservations appropriées telles que la réservation 23 sont prévues dans les éléments amovibles de lestage 9 pour le passage des boulons d'assemblage des traverses au cadre rigide.The rigid frame 11 is for example fixed to the respective crosspieces 16 and 17 by bolting, the bolt passing through respective holes shown in the figures. Appropriate reservations such as reservation 23 are provided in the removable ballast elements 9 for the passage of the assembly bolts of the crosspieces to the rigid frame.

Des panneaux tels que le panneau 24 rectangulaire sont fixés entre les montants successifs tels que les montants 19 et 20. La fixation des panneaux s'effectue de préférence par boulonnage dans des trous ménagés dans des pattes respectives de fixation dépassant latéralement des montants et des bords verticaux des panneaux. Par exemple, une fixation est prévue par boulonnage dans les pattes respectives de fixation 25 du montant 20 et 26 du bord vertical gauche du panneau 24.Panels such as the rectangular panel 24 are fixed between the successive uprights such as the uprights 19 and 20. The fixing of the panels is preferably carried out by bolting in holes made in respective fixing lugs projecting laterally from the uprights and edges vertical panels. For example, a fixing is provided by bolting in the respective fixing lugs 25 of the upright 20 and 26 of the left vertical edge of the panel 24.

Dans le mode de réalisation de la figure 1, la clôture est de hauteur relativement réduite. Ce mode de réalisation est adapté pour une hauteur de 120 centimètres environ. L'élément de clôture peut alors comprendre un seul panneau 24 rectangulaire, et les montants 19 et 20 sont simplement soudés sur les traverses respectives 16 et 17.In the embodiment of Figure 1, the fence is of relatively reduced height. This embodiment is suitable for a height of approximately 120 centimeters. The fence element can then comprise a single rectangular panel 24, and the uprights 19 and 20 are simply welded to the respective crosspieces 16 and 17.

Dans le mode de réalisation de la figure 2, la hauteur de clôture est sensiblement le double de la hauteur du mode de réalisation de la figure 1, et les montants 19 et 20 reçoivent deux panneaux 24 et 124, par exemple identiques.In the embodiment of Figure 2, the fence height is substantially double the height of the embodiment of Figure 1, and the uprights 19 and 20 receive two panels 24 and 124, for example identical.

Le mode de réalisation de la figure 3 est adapté à des barrières de plus grande hauteur, la hauteur totale étant sensiblement le triple de la hauteur de la barrière du mode de réalisation de la figure 1. Dans ce cas, les montants 19 et 20 reçoivent trois panneaux 24, 124 et 224 disposés les uns au-dessus des autres. Pour rigidifier une telle structure, les montants 19 et 20 sont associés à des contre-fiches 27 et 28 de rigidification reliant une zone élevée du montant respectif 19 ou 20 à la zone d'extrémité de la traverse correspondante 16 ou 17.The embodiment of FIG. 3 is suitable for barriers of greater height, the total height being substantially three times the height of the barrier of the embodiment of FIG. 1. In this case, the uprights 19 and 20 receive three panels 24, 124 and 224 arranged one above the other. To stiffen such a structure, the uprights 19 and 20 are associated with stiffening struts 27 and 28 connecting an elevated area of the respective upright 19 or 20 to the end area of the corresponding cross member 16 or 17.

Comme l'illustrent les figures 5 et 6, le boulonnage des panneaux est assuré de préférence par des tiges filetées telles que la tige 29, traversant les trous respectifs 30 et 31 ménagés dans les pattes respectives 25 du montant 20 et 26 du cadre 24. Aux extrémités de la tige filetée 29, on visse des capuchons borgnes taraudés 32 et 33, dont la paroi d'extrémité 34 est conformée pour être actionnée en rotation par un outil spécial, interdisant ainsi un dévissage intempestif par les outils traditionnels. Par exemple, on ménage sur la face d'extrémité 34 deux ou plusieurs trous dans lesquels viennent s'engager des ergots correspondants d'un outil de vissage.As illustrated in FIGS. 5 and 6, the bolting of the panels is preferably ensured by threaded rods such as the rod 29, passing through the respective holes 30 and 31 formed in the respective tabs 25 of the upright 20 and 26 of the frame 24. At the ends of the threaded rod 29, threaded blind caps 32 and 33 are screwed, the end wall 34 of which is shaped to be actuated in rotation by a special tool, thus preventing untimely unscrewing by traditional tools. For example, on the end face 34 are housed two or more holes into which engage corresponding lugs of a screwing tool.

La figure 7 illustre, en vue de dessus, une forme particulière d'élément amovible de lestage. L'ensemble constitue un secteur circulaire en quart de cercle, formé de deux éléments amovibles de lestage 35 et 36.FIG. 7 illustrates, in top view, a particular form of removable ballasting element. The assembly constitutes a circular sector in a quarter circle, formed by two removable ballasting elements 35 and 36.

La figure 4 est une vue en perspective montrant un assemblage d'éléments de clôture selon l'invention pour former la zone de clôture proche des buts d'un terrain de sport.Figure 4 is a perspective view showing an assembly of fence elements according to the invention to form the fence area close to the goals of a sports field.

On reconnaît, dans cet assemblage, deux éléments d'extrémité 3 et 103, à trois panneaux chacun, du type de celui décrit dans le mode de réalisation de la figure 3, et bordant un ensemble central 50. L'ensemble central 50 comprend un panneau supérieur 51, en alignement des panneaux des éléments latéraux 3 et 103, un montant central 52 en recul et associé à une traverse 53 en arrière de la zone occupée par les secondes parties rigides de structure des éléments de clôture 3 et 103. La traverse 53 est associée à deux cadres rigides 54 et 55, disposés de part et d'autre de la traverse centrale 53, et venant border partiellement les côtés postérieurs des cadres rigides d'éléments latéraux 3 et 103. Des cadres de raccordement en secteur à quart de cercle 56 et 57 prolongent les cadres rigides rectangulaires respectifs 54 et 55, et réalisent une surface élargie dans les zones latérales, surface permettant par exemple le retournement de fauteuils d'handicapés.We recognize, in this assembly, two end elements 3 and 103, with three panels each, of the type described in the embodiment of Figure 3, and bordering a central assembly 50. The central assembly 50 comprises a upper panel 51, in alignment with the panels of the lateral elements 3 and 103, a central upright 52 receding and associated with a cross-member 53 behind the area occupied by the second rigid structural parts of the closing elements 3 and 103. The cross-member 53 is associated with two rigid frames 54 and 55, disposed on either side of the central crosspiece 53, and partially bordering the rear sides of the rigid frames of lateral elements 3 and 103. Connection frames in quarter-circle sector 56 and 57 extend the respective rectangular rigid frames 54 and 55, and provide an enlarged surface in the lateral zones, a surface allowing for example the overturning of disabled wheelchairs.

Le montant central 52 porte une potence 58 dont l'extrémité porte un panier de basket ball 59.The central upright 52 carries a bracket 58 whose end carries a basketball hoop 59.

Le panneau supérieur 51 est fixé aux deux montants adjacents des éléments latéraux 3 et 103. L'espace situé au-dessous du panneau supérieur 51 constitue l'ouverture des buts. Dans la zone d'ouverture des buts, les deux montants adjacents des éléments latéraux 3 et 103 sont recouverts par des montants secondaires respectifs 61 et 60 à section ronde, dépourvus de pattes d'accrochage sur la surface apparente. Des éléments amovibles de lestage sont en appui sur tous les cadres rigides, la figure représentant certains seulement des éléments en cours d'assemblage. Les cadres de raccordement reçoivent des éléments 35 et 36 en secteur circulaire représentés sur la figure 7.The upper panel 51 is fixed to the two adjacent uprights of the side elements 3 and 103. The space below the upper panel 51 constitutes the opening of the goals. In the goal opening zone, the two adjacent uprights of the lateral elements 3 and 103 are covered by respective secondary uprights 61 and 60 of round section, devoid of hooking lugs on the visible surface. Removable ballast elements are supported on all the rigid frames, the figure representing some only of the elements being assembled. The connection frames receive elements 35 and 36 in a circular sector shown in FIG. 7.

La figure 10 illustre le panneau 24 dans un mode de réalisation dans le lequel le panneau comprend un cadre périphérique 70 en tube d'acier à section circulaire sur lequel est soudé un treillis soudé 71 à maille carrée, réalisé par exemple en fil de diamètre égal à 5 millimètres environ. Un tel panneau peut avoir une longueur de 2,40 mètres et une hauteur de 1 mètre environ.FIG. 10 illustrates the panel 24 in an embodiment in which the panel comprises a peripheral frame 70 of circular section steel tube on which is welded a welded mesh 71 with square mesh, made for example of wire of equal diameter about 5 millimeters. Such a panel can have a length of 2.40 meters and a height of about 1 meter.

La figure 11 illustre un second mode de réalisation du panneau 24, dans lequel le treillis soudé est remplacé par des lisses 72 en bois, solidaires du cadre 70 métallique.FIG. 11 illustrates a second embodiment of the panel 24, in which the welded mesh is replaced by wooden beams 72, integral with the metal frame 70.

La figure 12 illustre un autre mode de réalisation dans lequel le cadre est un treillis soudé 73.FIG. 12 illustrates another embodiment in which the frame is a welded mesh 73.

La figure 8 illustre, en vue de dessus, un terrain de sport entouré d'une clôture selon l'invention. Les éléments de clôture sont disposés tout autour du terrain de sport 80, les montants tels que le montant 81 étant adjacents au terrain de sport, les cadres et les éléments amovibles de lestage tels que l'élément 82 étant déportés vers l'extérieur du terrain de sport. Les éléments de lestage 82 constituent ainsi une zone périphérique externe plate sur laquelle peuvent se déplacer les utilisateurs. Les zones de buts 83 et 84 sont constituées par exemple comme le représente la figure 4. On peut avantageusement prévoir une chicane de pénétration 85, constituée d'un élément de clôture disposé selon une orientation opposée aux éléments adjacents, c'est-à-dire avec les éléments amovibles de lestage et les cadres rigides orientés vers l'intérieur du terrain de sport, l'élément de clôture étant toutefois déporté vers l'extérieur comme le représente la figure.Figure 8 illustrates, in top view, a sports field surrounded by a fence according to the invention. The fence elements are arranged all around the sports ground 80, the uprights such as the upright 81 being adjacent to the sports ground, the frames and the removable ballast elements such as the element 82 being offset towards the outside of the field sport. The ballasting elements 82 thus constitute a flat external peripheral zone over which the users. The end zones 83 and 84 are constituted for example as shown in FIG. 4. It is advantageously possible to provide a penetration baffle 85, consisting of a fence element arranged in an orientation opposite to the adjacent elements, that is to say say with the removable ballast elements and the rigid frames oriented towards the inside of the sports field, the fence element being however offset towards the outside as shown in the figure.

La figure 9 illustre un mode d'utilisation des éléments de clôture selon l'invention pour la réalisation d'une aire de rencontre. Plusieurs éléments de clôture similaires à celui du mode de réalisation de la figure 1 sont disposés les uns à la suite des autres, pour former un cercle ouvert, les éléments de lestage 9 étant orientés vers l'intérieur du cercle. Des sièges 90 peuvent être disposés sur les éléments de lestage, les panneaux tels que le panneau 24 constituant un dossier pour les sièges.Figure 9 illustrates a mode of use of the fence elements according to the invention for the realization of a meeting area. Several closing elements similar to that of the embodiment of FIG. 1 are arranged one after the other, to form an open circle, the ballasting elements 9 being oriented towards the inside of the circle. Seats 90 can be arranged on the ballast elements, the panels such as the panel 24 constituting a backrest for the seats.

La figure 13 illustre un mode de réalisation d'éléments de clôture dans lequel la seconde partie rigide 7 de structure comprend deux zones de seconde partie rigide 7 de structure qui se développent respectivement dans l'un et l'autre des demi-plans de part et d'autre de la base 8 de la première partie rigide 6 de structure.FIG. 13 illustrates an embodiment of fence elements in which the second rigid part 7 of structure comprises two zones of second rigid part 7 of structure which develop respectively in one and the other of the half-planes on the part and other of the base 8 of the first rigid part 6 of structure.

Chaque zone de seconde partie rigide 7 de structure a une structure similaire de celle de la seconde partie rigide de structure des modes de réalisation des figures 1 à 3. Elle comprend ainsi un cadre 11, des éléments amovibles de lestage 9, des traverses 16, 17 solidarisées aux montants 19, 20.Each second rigid part 7 of structural area has a structure similar to that of the second rigid structural part of the embodiments of FIGS. 1 to 3. It thus comprises a frame 11, removable ballasting elements 9, cross members 16, 17 secured to the uprights 19, 20.

La présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle en inclut les diverses variantes et généralisations contenues dans le domaine des revendications ci-après. On pourra notamment concevoir un élément de clôture dont la première partie rigide 6 de structure est destinée à être inclinée selon un angle approprié par rapport à la verticale : l'angle formé entre les deux parties rigides de structure est alors un angle non droit.The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof contained in the field of claims below. We can in particular design a fence element whose first rigid part 6 of structure is intended to be inclined at an appropriate angle relative to the vertical: the angle formed between the two rigid parts of structure is then a non-right angle.
