Description

La présente invention concerne un élément de barrière amovible utilisable avec d'autres éléments amovibles permettant de constituer une barrière dite de sécurité tel que décrit dans la première partie de la revendication 1.The present invention relates to a removable barrier element which can be used with other removable elements making it possible to constitute a so-called security barrier as described in the first part of claim 1.

Une telle barrière est couramment utilisée pour, par exemple, délimiter une aire, interdire un accès ou canaliser une foule lors d'une manifestation de rue, notamment. Elle est constituée par assemblage d'éléments métalliques bien connus, chaque élément comprenant un cadre rectangulaire horizontal, muni de barres transversales parallèles, des pieds situés dans le prolongement des montants latéraux du cadre et des moyens d'accrochage aux éléments adjacents, situés sur ces montants latéraux.Such a barrier is commonly used to, for example, delimit an area, prohibit access or channel a crowd during a street demonstration, in particular. It is formed by assembling well-known metallic elements, each element comprising a horizontal rectangular frame, provided with parallel transverse bars, feet situated in the extension of the lateral uprights of the frame and means for hooking to the adjacent elements, situated on these side uprights.

Il est souvent nécessaire de permettre le franchissement contrôlé de cette barrière, en un point précis de celle-ci. Pour réaliser un tel franchissement, il est usuel de ne pas accrocher deux éléments consécutifs et de les orienter en oblique par rapport à la barrière, afin de délimiter un passage.It is often necessary to allow controlled crossing of this barrier, at a specific point of it. To achieve such a crossing, it is usual not to hang two consecutive elements and to orient them obliquely relative to the barrier, in order to delimit a passage.

Ce décrochage présente l'inconvénient de rompre la continuité de la barrière et de rendre un renversement ou le déplacement de l'un ou l'autre des deux tronçons de celle-ci possible, en cas de mouvement de foule incontrôlé.This stall has the drawback of breaking the continuity of the barrier and of making it possible for one or the other of the two sections to overturn or move, in the event of uncontrolled crowd movement.

De plus, ce décrochage peut être difficile à réaliser dans certains cas, et les moyens d'accrochage, constitués par des pattes recourbées en forme de crochet, sont exposés au passage de la foule et peuvent être blessants.In addition, this stall can be difficult to achieve in some cases, and the attachment means, constituted by hook-shaped curved legs, are exposed to the passage of the crowd and can be injurious.

Le brevet britannique n° 679 297 décrit des éléments de barrière permettant de constituer une barrière de sécurité. Il est prévu un élément comprenant une plaque inférieure formant une semelle, deux montants latéraux indépendants l'un de l'autre, fixés aux extrémités de cette plaque, et un portillon monté pivotant sur l'un de ces montants.British Patent No. 679,297 describes barrier elements for constituting a safety barrier. An element is provided comprising a lower plate forming a sole, two lateral uprights independent of each other, fixed to the ends of this plate, and a door pivotally mounted on one of these uprights.

Cet élément à portillon a pour inconvénient de ne présenter qu'une solidité longitudinale limitée, de sorte qu'il serait sans aucun doute amené à se déformer en cas de contrainte longitudinale exercée sur la barrière, à la suite d'un mouvement de foule, par exemple. Cette déformation pourrait provoquer le décrochage des éléments, et donc la rupture de la continuité de la barrière, qui pourrait se renverser. De plus, les extrémités de ces montants peuvent être blessantes en cas de mouvement de foule, particulièrement en cas de déformation et de torsion de cet élément.This flap element has the disadvantage of having only a limited longitudinal solidity, so that it would undoubtedly have to deform in the event of longitudinal stress exerted on the barrier, following a crowd movement, for example. This deformation could cause the elements to drop out, and therefore break the continuity of the barrier, which could overturn. In addition, the ends of these uprights can be offensive in the event of crowd movement, particularly in the event of deformation and torsion of this element.

En outre, l'élément à portillon décrit par le brevet britannique n° 679 297 n'est adaptable qu'aux barrières spécifiquement décrites par ce document et non aux barrières couramment utilisées en pratique, et a pour inconvénient de ne pas comprendre de système de verrouillage et de décrochage rapide.In addition, the wicket element described by British Patent No. 679,297 is only adaptable to the barriers specifically described by this document and not to the barriers commonly used in practice, and has the disadvantage of not comprising a system of locking and quick release.

L'invention vise à remédier à ces inconvénients, en fournissant un élément de barrière permettant le franchissement aisé et contrôlé d'une barrière dite "de sécurité". Elle vise également à fournir un élément simple à fabriquer, à transporter et à manipuler.The invention aims to remedy these drawbacks by providing a barrier element allowing the easy and controlled crossing of a so-called "security" barrier. It also aims to provide an element that is simple to manufacture, transport and handle.

L'élément qu'elle concerne comprend, de manière connue en soi, des montants latéraux munis de moyens d'accrochage aux éléments de barrière adjacents, et un battant pivotant, pouvant être verrouillé dans le plan de la barrière, pour interdire tout franchissement de celle-ci, et être effacé par pivotement, pour permettre le passage de personnes de part et d'autre de la barrière.The element which it concerns comprises, in a manner known per se, lateral uprights provided with means for hooking to the adjacent barrier elements, and a pivoting leaf, which can be locked in the plane of the barrier, to prevent any crossing of this, and be erased by pivoting, to allow the passage of people on either side of the barrier.

Selon l'invention, les montants latéraux de l'élément se prolongent vers le haut et sont reliés l'un à l'autre, à leur partie supérieure, par une traverse, cette traverse étant située à une hauteur telle qu'elle permet le passage d'une personne.According to the invention, the lateral uprights of the element extend upwards and are connected to each other, at their upper part, by a cross member, this cross member being situated at a height such that it allows the passage of a person.

L'élément selon l'invention comprend ainsi un cadre rectangulaire faisant saillie verticalement en cours d'utilisation. Ce cadre confère une bonne homogénéité de structure à l'élément, permettant à ce dernier de résister sans dommages aux efforts longitudinaux que peut subir la barrière ou aux manipulations et transport, et constitue une embrasure permettant le passage facile, sûr et contrôlé de personnes.The element according to the invention thus comprises a rectangular frame projecting vertically in progress of use. This frame gives good structural homogeneity to the element, allowing the latter to resist without damage to the longitudinal forces which the barrier may undergo or to handling and transport, and constitutes a recess allowing the easy, safe and controlled passage of people.

La partie supérieure de l'élément peut recevoir un panneau comprenant des indications telles que "ENTREE", "SORTIE", ou "CAISSE", par exemple, aisément visibles du public.The upper part of the element can receive a panel comprising indications such as "ENTRY", "EXIT", or "CASE", for example, easily visible to the public.

Selon un autre aspect de l'invention, l'élément de barrière comprend au moins deux barres latérales formant des pieds de maintien de l'élément en position verticale, qui sont articulées, à leur partie supérieure, à l'un des montants latéraux de l'élément et qui comprennent, à leur partie inférieure, des tiges escamotables formant, en position active, une entretoise de maintien des barres en position déployée, et ne faisant pas obstacle, en position effacée, au rabat des barres contre les montants latéraux de l'élément.According to another aspect of the invention, the barrier element comprises at least two lateral bars forming feet for holding the element in a vertical position, which are articulated, at their upper part, to one of the lateral uprights of the element and which comprise, at their lower part, retractable rods forming, in the active position, a spacer for holding the bars in the deployed position, and not obstructing, in the erased position, the flap of the bars against the lateral uprights of the item.

Ces barres assurent un maintien stable de l'élément lorsqu'elles sont déployées et n'ont qu'un faible encombrement lorsqu'elles sont rabattues contre l'élément.These bars ensure stable maintenance of the element when they are deployed and have only a small footprint when they are folded against the element.

Selon une forme de réalisation préférée de l'invention, dans ce cas, l'élément comprend deux paires de barres latérales formant des pieds, chaque paire étant montée pivotante sur l'un des montants latéraux de l'élément ; les deux barres situées du même côté de l'élément sont reliées l'une à l'autre par une même tige escamotable pivotante, coudée au moins deux fois pour présenter une partie médiane allongée parallèle à une traverse inférieure que l'élément comprend ; et cette traverse inférieure de l'élément comprend des rainures aptes à recevoir et à retenir amoviblement les parties médianes allongées des tiges.According to a preferred embodiment of the invention, in this case, the element comprises two pairs of lateral bars forming feet, each pair being pivotally mounted on one of the lateral uprights of the element; the two bars located on the same side of the element are connected to one another by the same pivoting retractable rod, bent at least twice to present an elongated middle part parallel to a lower crosspiece that the element comprises; and this lower cross member of the element comprises grooves capable of receiving and removably retaining the elongated middle parts of the rods.

Ainsi conformé, l'élément selon l'invention est particulièrement simple à manipuler.Thus shaped, the element according to the invention is particularly simple to handle.

Selon une forme de réalisation préférée des moyens d'accrochage de l'élément à d'autres éléments de barrière, l'un des montants latéraux de l'élément comprend des pattes recourbées en forme de crochet, susceptibles d'être engagées autour du montant latéral correspondant de l'élément voisin ; ces pattes comportent des biellettes reliées à une barre de verrouillage, cette barre de verrouillage étant mobile, par pivotement des biellettes, entre une position effacée, dans laquelle le montant latéral de l'élément de barrière adjacent peut être introduit dans les pattes ou dégagé hors de celles-ci, et une position de verrouillage, dans laquelle elle vient en contact avec le montant latéral de l'élément de barrière adjacent, de manière à le maintenir dans le fond des parties recourbées des pattes et à empêcher tout dégagement de ce montant hors de ces pattes.According to a preferred embodiment of the means for attaching the element to other barrier elements, one of the lateral uprights of the element comprises hook-shaped curved legs, capable of being engaged around the upright corresponding side of the neighboring element; these tabs comprise connecting rods connected to a locking bar, this locking bar being movable, by pivoting of the connecting rods, between a retracted position, in which the lateral upright of the adjacent barrier element can be introduced into the tabs or released out of these, and a locking position, in which it comes into contact with the lateral upright of the adjacent barrier element, so as to keep it in the bottom of the curved portions of the legs and to prevent any release of this upright out of these legs.

Ce système permet en outre un décrochage rapide, afin de créer, si nécessaire, un grand passage, et permet l'adaptation de l'élément à portillon selon l'invention, au type de barrières de rues couramment utilisées en pratique.This system also allows a quick release, in order to create, if necessary, a large passage, and allows the adaptation of the gate element according to the invention, to the type of street barriers commonly used in practice.

L'accrochage de l'élément selon l'invention à un élément de barrière adjacent est ainsi réalisé de manière parfaitement sûre, et tout risque de décrochage est évité. La barre peut être immobilisée en position de verrouillage par un moyen approprié, tel qu'un cadenas.The attachment of the element according to the invention to an adjacent barrier element is thus carried out in a perfectly safe manner, and any risk of detachment is avoided. The bar can be immobilized in the locked position by an appropriate means, such as a padlock.

Pour sa bonne compréhension, l'invention est à nouveau décrite ci-dessous en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme de réalisation préférée de l'élément qu'elle concerne.

  • la figure 3 est une vue de détail, à échelle agrandie, de ses moyens d'accrochage et de verrouillage à un élément de barrière adjacent, et
  • la figure 4 en est une vue en coupe selon la ligne IV-IV de la figure 1.
For a good understanding, the invention is again described below with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, a preferred embodiment of the element which it concerns.
  • Figure 1 is a front view, in elevation, while it is attached to two adjacent barrier elements;
  • Figure 2 is a side view;
  • FIG. 3 is a detail view, on an enlarged scale, of its means for hooking and locking to an adjacent barrier element, and
  • Figure 4 is a sectional view along the line IV-IV of Figure 1.

Les figures 1 et 2 représentent, sous différents angles, un élément de barrière 1 utilisable avec des éléments de barrière 2 permettant de constituer une barrière dite "de sécurité".Figures 1 and 2 show, from different angles, a barrier element 1 usable with barrier elements 2 making it possible to constitute a so-called "security" barrier.

Les éléments 2 sont bien connus. Chacun comprend un cadre rectangulaire horizontal 3 muni de barres transversales parallèles 4, des pieds 5 situés ou non dans le prolongement des montants latéraux 3a du cadre 3 et des pattes saillantes 6, recourbées en forme de crochet, qui sont situées sur l'un des montants latéraux 3a. Ces pattes 6 peuvent recevoir le montant 3a dépourvu de pattes 6 d'un élément 2 adjacent, et permettent ainsi l'accrochage des éléments 2 les uns à la suite des autres.Elements 2 are well known. Each comprises a horizontal rectangular frame 3 provided with parallel transverse bars 4, feet 5 located or not in the extension of the lateral uprights 3a of the frame 3 and projecting legs 6, curved in the shape of a hook, which are located on one of the lateral uprights 3a. These legs 6 can receive the amount 3a devoid of legs 6 of an adjacent element 2, and thus allow the attachment of the elements 2 one after the other.

L'élément 1 comprend un cadre rectangulaire 10, orienté verticalement en cours d'utilisation, qui est muni d'une traverse supérieure 12 supportant un panneau 13 et d'une traverse inférieure 14 comportant deux étriers 15. Ces étriers 15 délimitent des rainures latérales 15a, comme le montre la figure 2.The element 1 comprises a rectangular frame 10, oriented vertically during use, which is provided with an upper cross member 12 supporting a panel 13 and a lower cross member 14 comprising two stirrups 15. These stirrups 15 delimit lateral grooves 15a, as shown in Figure 2.

Le panneau 13 comporte des indications telles que "ENTREE", "SORTIE", ou "CAISSE", par exemple.The panel 13 includes indications such as "ENTER", "EXIT", or "CASE", for example.

L'un des montants latéraux 10a du cadre 10 est muni de pattes saillantes 16 pour l'accrochage à un élément 2 adjacent, et l'autre montant latéral 10a peut être engagé dans les pattes 6 de l'autre élément 2 adjacent.One of the lateral uprights 10a of the frame 10 is provided with projecting lugs 16 for attachment to an adjacent element 2, and the other lateral upright 10a can be engaged in the lugs 6 of the other adjacent element 2.

En outre, l'un des montants latéraux 10a comporte un battant 20, pivotant autour d'un axe vertical. Ce battant 20 est formé par un élément de bordure 21 en U, des barres transversales 22 et des pattes 23, de butée du battant 20 en position fermée, visibles à la figure 4.In addition, one of the lateral uprights 10a has a leaf 20, pivoting about a vertical axis. This leaf 20 is formed by a U-shaped edge element 21, transverse bars 22 and lugs 23, of the leaf 20 stop in the closed position, visible in FIG. 4.

Le cadre 10 comprend en outre deux paires de barres latérales 25 formant des pieds de maintien de l'élément 1 en position verticale. Ces barres 25 sont montées pivotantes, à leur partie supérieure, sur les montants latéraux 10a, autour d'un axe perpendiculaire à ces montants. Les deux barres 25 situées du même côté du cadre 10 sont reliées l'une à l'autre par une tige pivotante 26. Chaque tige 26 est coudée quatre fois à angle droit pour former deux tourillons d'extrémité coaxiaux, engagés au travers des barres 25, qui permettent le pivotement de la tige 26 par rapport aux barres 25, et une partie médiane allongée 26a, parallèle à la traverse inférieure 14 du cadre 10.The frame 10 further comprises two pairs of side bars 25 forming feet for holding the element 1 in a vertical position. These bars 25 are pivotally mounted, at their upper part, on the lateral uprights 10a, around an axis perpendicular to these uprights. The two bars 25 located on the same side of the frame 10 are connected to each other by a pivoting rod 26. Each rod 26 is bent four times at right angles to form two coaxial end journals, engaged through the bars 25, which allow the rod 26 to pivot relative to the bars 25, and an elongated middle part 26a, parallel to the lower cross member 14 of the frame 10.

Les tiges 26 sont mobiles entre une position active et une position effacée. En position active, leurs parties médianes allongées 26a peuvent être reçues et être retenues amoviblement dans les rainures 15a, comme cela apparaît à la figure 2, formant ainsi des entretoises de maintien des barres 25 en position déployée. En position effacée, les tiges 26 ne font pas obstacle au rabat des barres 25 contre les montants 10a.The rods 26 are movable between an active position and an erased position. In the active position, their elongated middle portions 26a can be received and be detachably retained in the grooves 15a, as appears in FIG. 2, thus forming spacers for holding the bars 25 in the deployed position. In the retracted position, the rods 26 do not obstruct the flap of the bars 25 against the uprights 10a.

Le montant latéral 10a comprenant les pattes 16 est en outre muni d'une barre de verrouillage 30 à section en T, reliée à ces pattes 16 par l'intermédiaire de deux biellettes doubles 31, l'ensemble formant un parallélogramme déformable. Comme le montre la figure 3, cette barre de verrouillage 30 est mobile entre une position effacée, représentée en traits mixtes, dans laquelle le montant latéral 3a de l'élément de barrière 2 adjacent peut être introduit dans les pattes 16 ou dégagé hors de celles-ci, et une position de verrouillage, représentée en traits pleins, dans laquelle la barre 30 vient en contact avec le montant latéral 3a, de manière à le maintenir dans le fond de la partie recourbée des pattes 16 et à empêcher tout dégagement de ce montant 3a hors de ces pattes 16.The lateral upright 10a comprising the legs 16 is further provided with a locking bar 30 with T-section, connected to these legs 16 by means of two double links 31, the assembly forming a deformable parallelogram. As shown in FIG. 3, this locking bar 30 is movable between an erased position, shown in phantom, in which the lateral upright 3a of the adjacent barrier element 2 can be introduced into the legs 16 or released from those -ci, and a locking position, shown in solid lines, in which the bar 30 comes into contact with the lateral upright 3a, so as to maintain it in the bottom of the curved part of the legs 16 and to prevent any release of this amount 3a out of these legs 16.

La figure 4 montre que l'élément 1 comprend également un loquet pivotant 40, venant, dans la position représentée, en face des butées 23 et assurant ainsi le verrouillage du battant 20 en position fermée, et pouvant être effacé pour permettre l'ouverture du battant 20. Ce loquet 40 est monté, par simplification, sur le même axe 41 que celui permettant le pivotement de la biellette 31 supérieure.Figure 4 shows that the element 1 also comprises a pivoting latch 40, coming, in the position shown, opposite the stops 23 and thus ensuring the locking of the leaf 20 in the closed position, and which can be erased to allow the opening of the leaf 20. This latch 40 is mounted, for simplicity, on the same axis 41 as that allowing the pivoting of the upper link 31.

Il va de soi que l'invention n'est pas limitée à la forme de réalisation décrite ci-dessus à titre d'exemple mais qu'elle en embrasse, au contraire, toutes les variantes de réalisation.It goes without saying that the invention is not limited to the embodiment described above by way of example but that it embraces, on the contrary, all the variant embodiments.

Ainsi, l'une ou l'autre des pattes 16 et la barre 30 peuvent comprendre des trous venant en face l'un de l'autre en position active de la barre 30, permettant le passage d'un moyen de verrouillage approprié, tel que la anse d'un cadenas, qui assure l'immobilisation de la barre 30 dans cette position active.Thus, one or the other of the legs 16 and the bar 30 may comprise holes coming opposite one another in the active position of the bar 30, allowing the passage of an appropriate locking means, such as that the handle of a padlock, which ensures the immobilization of the bar 30 in this active position.

Le loquet 40 peut également comprendre un trou venant en face de ces deux trous en position de verrouillage du battant 20, de sorte que ce loquet peut être immobilisé par ce même moyen de verrouillage ou cadenas.The latch 40 may also include a hole coming opposite these two holes in the locking position of the leaf 20, so that this latch can be immobilized by this same locking means or padlock.

L'invention fournit ainsi un élément de barrière muni d'un battant, permettant d'interdire tout franchissement de la barrière lorsque le battant est fermé, ou tout décrochage des éléments 1 et 2 lorsque la barre 30 est verrouillée en position active.The invention thus provides a barrier element provided with a leaf, making it possible to prohibit any crossing of the barrier when the leaf is closed, or any stalling of the elements 1 and 2 when the bar 30 is locked in the active position.

Lorsque le battant 20 est ouvert, l'élément 1 permet le passage aisé et contrôlé de personnes de part et d'autre de la barrière.When the leaf 20 is open, the element 1 allows the easy and controlled passage of people on either side of the barrier.
