Description

ARRIERE-PLANBACKGROUND DE L'INVENTIONOF THE INVENTION Domaine de l'inventionField of the invention

La présente invention a trait à une barrière de sécurité, et notamment une barrière de sécurité pour enfants.The present invention relates to a safety barrier, including a child safety barrier.

Arrière-plan technologiqueTechnological background

On connaît des barrières de sécurité utilisées pour empêcher des enfants d'accéder à des zones susceptibles d'être dangereuses telles que des escaliers, le garage, la salle de bain, ...Safety barriers are known to prevent children from accessing potentially dangerous areas such as stairs, the garage, the bathroom, etc.

Ces barrières peuvent comporter, à titre illustratif, deux montants latéraux fixés à l'encadrement d'une porte ou d'un escalier et un battant monté en pivotement sur l'un de ces montants latéraux. Une serrure assure le maintien en position de fermeture de la barrière. Ce battant présente l'avantage d'être facilement manoeuvrable.These barriers may comprise, for illustrative purposes, two lateral uprights fixed to the frame of a door or a staircase and a flap pivotally mounted on one of these lateral uprights. A lock ensures the maintenance in the closed position of the barrier. This wing has the advantage of being easily maneuverable.

Cependant, ce type de barrière nécessite généralement d'enjamber une traverse située au niveau du sol, laquelle sert à relier les divers éléments constitutifs de la barrière. Il existe donc un risque de chute pour l'enfant qui peut s'avérer grave lorsque cette barrière est disposée par exemple dans la partie haute d'un escalier.However, this type of barrier usually requires climbing over a ground-level tie, which serves to connect the various components of the barrier. There is therefore a risk of falling for the child that can be serious when the barrier is disposed for example in the upper part of a staircase.

De plus, l'installation de ces barrières étant longue et complexe, elles sont typiquement posées à poste fixe et ne se prêtent donc pas au suivi d'un déplacement momentané de l'enfant d'une pièce à une autre de la maison.In addition, the installation of these barriers being long and complex, they are typically posed stationary and therefore do not lend themselves to monitoring a momentary movement of the child from one room to another in the house.

On connaît encore des barrières de sécurité à pose et dépose rapide. Ces barrières présentent l'avantage de pouvoir être soulevées dans leur intégralité et déplacées aisément par un opérateur pour libérer l'accès à un passage.Safety barriers are still known for rapid installation and removal. These barriers have the advantage that they can be raised in their and easily moved by an operator to free access to a passage.

Une telle barrière est décrite dans le brevet français FR 2925101 au nom de la présente demanderesse. D'après la Figure 1, cette barrière comprend un panneau d'obstruction 1 comportant des bords latéraux 2, 3 et deux montants latéraux 4, 5 supportant ce panneau d'obstruction 1. Ce panneau d'obstruction 1 ajouré comporte des barres verticales 6 reliées entre elles à chacune de leurs extrémités par une barre horizontale 7, 8 délimitant les extrémités supérieure et inférieure de ce panneau d'obstruction 1.Such a barrier is described in the French patent FR 2925101 on behalf of the plaintiff. According to Figure 1 , this barrier comprises an obstruction panel 1 having lateral edges 2, 3 and two lateral uprights 4, 5 supporting this obstruction panel 1. This openwork obstruction panel 1 comprises vertical bars 6 interconnected to each of their ends by a horizontal bar 7, 8 delimiting the upper and lower ends of this obstruction panel 1.

Le panneau d'obstruction 1 est relié à chacun de ces montants latéraux 4, 5 de manière pivotante par deux organes de couplage 9 de sorte qu'un déplacement en translation de ce panneau d'obstruction 1 par rapport à ces montants latéraux 4, 5 entraîne un rapprochement ou un éloignement des bords latéraux 2, 3 du panneau d'obstruction avec les montants latéraux 4, 5 causant respectivement l'ouverture 10 ou la fermeture 11 de la barrière lorsque celle-ci est placée dans un passage dont l'accès est destiné à être barré.The obstruction panel 1 is connected to each of these lateral uprights 4, 5 pivotally by two coupling members 9 so that a displacement in translation of the obstruction panel 1 with respect to these lateral uprights 4, 5 causes the lateral edges 2, 3 of the obstruction panel to be moved closer to or away from the lateral uprights 4, 5 respectively causing the opening 10 or the closing 11 of the barrier when the latter is placed in a passage whose access is intended to be barred.

Bien que cette barrière de sécurité soit aisée à manoeuvrer, légère et robuste, elle peut encore être améliorée en terme de sécurité.Although this safety barrier is easy to maneuver, light and robust, it can be further improved in terms of safety.

Notamment, on s'est aperçu que des enfants pouvaient apprendre à actionner la barrière en observant les adultes manoeuvrer celle-ci devant eux.Notably, it became apparent that children could learn to operate the barrier by watching the adults maneuver it in front of them.

On connaît également dans l'état de la technique la demande PCT N° WO 2012/107335 A1 , qui est un document selon l'Article 54(3) de la Convention sur le Brevet Européen. Ce document de l'état de la technique décrit une barrière de sécurité comportant un élément de barrière, mais qui ne présente pas le même niveau de sécurité que la présente invention.It is also known in the state of the art the demand PCT No. WO 2012/107335 A1 , which is a document under Article 54 (3) of the European Patent Convention. This prior art document describes a safety barrier having a barrier element, but which does not exhibit the same level of security as the present invention.

Il convient dès lors de complexifier le mécanisme de déblocage de la barrière afin de s'assurer qu'un enfant ne puisse ouvrir seul la barrière tout en conservant la simplicité d'utilisation de la présente barrière qui en fait son principal attrait.It is therefore necessary to complicate the mechanism of unlocking the barrier to ensure that a child can not open the barrier alone while maintaining the ease of use of the present barrier which makes it its main attraction.

En particulier, cette barrière doit pouvoir être manoeuvrée d'une seule main par un adulte.In particular, this barrier must be able to be maneuvered with one hand by an adult.

Cette barrière doit également pouvoir être posée rapidement pour bloquer temporairement un passage et en conséquence, ne pas nécessiter de perçage pour sa pose qui viendrait endommager les éléments structurels définissant le passage à barrer.This barrier must also be able to be laid quickly to temporarily block a passage and therefore, do not require drilling for its installation that would damage the structural elements defining the passage to bar.

L'objectif de la présente invention est donc de proposer une barrière de sécurité amovible, simple dans sa conception et dans son mode opératoire, répondant aux problèmes de l'art antérieur exposés ci-dessus.The object of the present invention is therefore to provide a removable safety barrier, simple in its design and its operating mode, responding to the problems of the prior art described above.

BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION

A cet effet, l'invention concerne une barrière de sécurité comprenant un panneau central, deux montants latéraux supportant ledit panneau central, ledit panneau central comportant des bords latéraux et étant relié à chacun desdits montants latéraux de manière pivotante par des éléments d'articulation de sorte qu'un déplacement en translation dudit panneau central par rapport auxdits montants latéraux entraîne un rapprochement ou un éloignement des bords latéraux dudit panneau central avec lesdits montants latéraux causant respectivement l'ouverture ou la fermeture de ladite barrière lorsque celle-ci est placée dans un passage dont l'accès est destiné à être barré.
Selon l'invention, cette barrière comporte

  • un moyen de blocage du déplacement d'au moins un desdits éléments d'articulation de manière à empêcher le déplacement en translation dudit panneau central par rapport auxdits montants latéraux lorsque ladite barrière étant dans sa position de fermeture, et
  • un dispositif de commande manuel permettant de déverrouiller ledit moyen de blocage pour autoriser ledit déplacement en translation dudit panneau central et permettre ainsi l'ouverture de ladite barrière.
To this end, the invention relates to a safety barrier comprising a central panel, two lateral uprights supporting said central panel, said central panel having lateral edges and being connected to each of said lateral uprights pivotally by hinge elements of so that translational movement of said central panel with respect to said lateral uprights causes the lateral edges of said central panel to approach or move away from said lateral uprights, respectively causing said barrier to open or close when said barrier is placed in a passage whose access is intended to be barred.
According to the invention, this barrier comprises
  • means for blocking the displacement of at least one of said hinge members so as to prevent translational displacement of said central panel with respect to said lateral uprights when said barrier is in its closed position, and
  • a manual control device for unlocking said locking means to allow said displacement in translation of said central panel and thus allow the opening of said barrier.

Chacun des bords latéraux du panneau central est avantageusement parallèle au bord intérieur du montant latéral avec lequel il est destiné à se rapprocher et à être plaqué dans la position d'ouverture de la barrière.Each of the lateral edges of the central panel is advantageously parallel to the inner edge of the lateral upright with which it is intended to come closer and to be plated in the open position of the barrier.

On entend par "bord intérieur du montant latéral", la partie du montant latéral qui est destinée à être placée en regard du panneau central de cette barrière. Cette barrière de sécurité est avantageusement réalisée en bois mais pourrait être également métallique ou en plastique.The term "inner edge of the lateral upright", the portion of the lateral amount which is intended to be placed next to the central panel of this barrier. This security barrier is advantageously made of wood but could also be metal or plastic.

De préférence, le panneau central est relié à chacun de ces deux montants latéraux par au moins deux éléments d'articulation formant avec le bord latéral du panneau central et du montant correspondant un parallélogramme déformable permettant de faire passer la barrière entre une première position dite de blocage où ledit panneau central étant dans une position abaissée, les bords extérieurs des montants latéraux ou les extrémités libres d'éléments d'appui formant saillie de ces bords extérieurs et dont la dimension longitudinale est variable, sont plaqués contre la ou les structures délimitant le passage pour fixer en position ladite barrière et une deuxième position dite de déblocage où ledit panneau central étant dans une position relevée par rapport aux montants latéraux, cette barrière n'est alors plus solidaire de ces structures.Preferably, the central panel is connected to each of these two lateral uprights by at least two hinge elements forming with the lateral edge of the central panel and the corresponding upright a deformable parallelogram making it possible to pass the barrier between a first position known as blocking wherein said central panel being in a lowered position, the outer edges of the lateral uprights or the free ends of bearing elements projecting from these outer edges and whose longitudinal dimension is variable, are pressed against the structure or structures delimiting the passage to fix in position said barrier and a second position called unblocking where said central panel being in a raised position relative to the lateral uprights, this barrier is then no longer integral with these structures.

Ces éléments d'articulation sont avantageusement d'une seule pièce.These articulation elements are advantageously in one piece.

Le plan de rotation de ces éléments d'articulation est confondu avec le plan contenant le panneau central.The plane of rotation of these articulation elements coincides with the plane containing the central panel.

Dans différents modes de réalisation particuliers de cette barrière de sécurité, chacun ayant ses avantages particuliers et susceptibles de nombreuses combinaisons techniques possibles:

  • ledit moyen de blocage comporte :
    • * un doigt relié audit panneau central, ou audit montant latéral comportant l'élément d'articulation dont le déplacement est destiné à être bloqué, ledit doigt étant mobile entre une position rétractée et une position dans laquelle il fait saillie respectivement d'un bord latéral dudit panneau central ou dudit montant latéral, et
    • * un logement placé sur, respectivement ledit montant latéral ou sur ledit bord latéral du panneau central, ledit logement étant destiné à recevoir ledit doigt pour assurer le blocage du déplacement en translation dudit panneau central par rapport audit montant latéral,
  • ledit dispositif de commande manuel comprend un curseur, un bouton ou une poignée.
In various particular embodiments of this safety barrier, each having its particular advantages and likely to have many possible technical combinations:
  • said blocking means comprises:
    • * A finger connected to said central panel, or said side upright comprising the articulation whose displacement is to be blocked element, said finger being movable between a retracted position and a position in which it protrudes respectively from one side edge said central panel or said lateral upright, and
    • * A housing placed on respectively said side upright or on said side edge of the central panel, said housing being intended to receive the said finger in order to lock the translational movement of said central panel relative to said side upright,
  • said manual control device comprises a slider, a button or a handle.

De préférence, le dispositif de commande manuel étant solidaire du doigt, ledit moyen de blocage comporte un moyen de rappel pour ramener ce doigt en position dans laquelle il fait saillie du bord latéral de sorte que le dispositif de commande doit être tenu manuellement pour maintenir ledit doigt dans sa position rétractée lors d'au moins une partie du déplacement dudit panneau central.

  • lesdits éléments d'articulation sont choisis dans le groupe comprenant une languette, une biellette, une plaque et une combinaison de ces éléments,
  • la barrière comporte au moins un élément de protection pour empêcher un éventuel pincement, par exemple, d'un doigt,
  • le panneau central est plein ou ajouré.
Preferably, the manual control device being integral with the finger, said locking means comprises a return means for bringing the finger into position in which it projects from the lateral edge so that the control device must be held manually to maintain said finger in its retracted position during at least part of the displacement of said central panel.
  • said hinge members are selected from the group consisting of a tongue, a link, a plate and a combination of these elements,
  • the barrier comprises at least one protective element to prevent any pinching, for example, of a finger,
  • the central panel is full or openwork.

De préférence, le panneau central étant ajouré, au moins un des montants latéraux comporte sur son bord intérieur, un dégagement permettant une prise d'appui du pied de l'opérateur pour faciliter le déplacement du panneau central vers sa position relevée.

  • le panneau central est de longueur variable.
Preferably, the central panel being perforated, at least one of the lateral uprights has on its inner edge, a clearance allowing a grip support of the operator's foot to facilitate the movement of the central panel to its raised position.
  • the central panel is of variable length.

L'invention concerne également un procédé d'ouverture d'une barrière placée dans un passage de sorte à en barrer l'accès, cette barrière comprenant un panneau central, deux montants latéraux supportant ce panneau central, le panneau central comportant des bords latéraux et étant relié à chacun desdits montants latéraux de manière pivotante par des éléments d'articulation de sorte qu'un déplacement en translation dudit panneau central par rapport à ces montants latéraux entraîne un rapprochement ou un éloignement des bords latéraux du panneau central avec les montants latéraux causant respectivement l'ouverture ou la fermeture de la barrière.The invention also relates to a method of opening a barrier placed in a passage so as to block access to it, this barrier comprising a central panel, two lateral uprights supporting this central panel, the central panel having lateral edges and being connected to each of said lateral uprights pivotally by hinge members so that translational movement of said center panel with respect to these side uprights causes the lateral edges of the central panel to be moved closer to or away from the lateral uprights causing respectively opening or closing the barrier.

Selon l'invention, on réalise au moins les étapes successives suivantes :

  • ladite barrière étant en position fermée et le déplacement d'au moins un desdits éléments d'articulation étant bloqué par un moyen de blocage solidarisant ledit panneau central au montant latéral supportant au moins une partie dudit élément d'articulation, on déverrouille ce moyen de blocage en actionnant un dispositif de commande manuel,
  • tout en conservant ledit dispositif de commande manuel actionné de sorte à autoriser le déplacement dudit au moins un élément d'articulation, on déplace en translation ledit panneau central par rapport auxdits montants latéraux de manière à rapprocher lesdits montants latéraux des bords latéraux dudit panneau central et assurer ainsi l'ouverture de ladite barrière.
According to the invention, at least the following successive steps are carried out:
  • said barrier being in the closed position and the displacement of at least one of said hinge elements being blocked by a locking means solidarisant said central panel to the lateral upright supporting at least a portion of said hinge member, it unlocks this locking means by operating a manual control device,
  • while keeping said manual control device actuated so as to allow the displacement of said at least one hinge member, said central panel is moved in translation with respect to said lateral uprights so as to bring said lateral uprights closer to the lateral edges of said central panel and thus ensure the opening of said barrier.

DESCRIPTIONDESCRIPTION DETAILLEE DE MODES DE REALISATION DE L'INVENTIONDETAILED EMBODIMENTS OF THE INVENTION

Tout d'abord, on note que les figures ne sont pas à l'échelle.First, we note that the figures are not scaled.

Les Figures 3 à 7 montrent une barrière de sécurité selon un premier mode de réalisation de la présente invention.The Figures 3 to 7 show a safety barrier according to a first embodiment of the present invention.

Cette barrière comprend un panneau central 12 ajouré qui est formé de deux traverses opposées dites traverses supérieure et inférieure, reliées entre elles par des barres verticales. Seule la traverse supérieure est ici représentée par souci de clarté de présentation de l'invention.This barrier comprises a central openwork panel 12 which is formed of two opposite crosspieces said upper and lower rails, interconnected by vertical bars. Only the upper cross is here shown for the sake of clarity of presentation of the invention.

La barrière comprend également deux montants latéraux 13 supportant ce panneau central 12. Le panneau central 12 ainsi que les deux montants latéraux 13 sont ici réalisés en bois.The barrier also comprises two lateral uprights 13 supporting this central panel 12. The central panel 12 and the two lateral uprights 13 are here made of wood.

Le panneau central 12 comporte des bords latéraux 14 qui sont déterminés par les extrémités des traverses supérieure et inférieure. Chaque bord latéral 14 du panneau central 12 est parallèle au bord intérieur du montant latéral 13 correspondant.The central panel 12 has side edges 14 which are determined by the ends of the upper and lower rails. Each lateral edge 14 of the central panel 12 is parallel to the inner edge of the corresponding lateral upright 13.

Chaque montant latéral 13 peut de plus comporter des éléments d'appui (non représentés) de ce montant à une structure qui peut être un barreau d'une balustrade, un côté d'un encadrement de porte, ou autre délimitant un bord du passage dont l'accès est destiné à être barré par la barrière. De préférence, la dimension longitudinale de ces éléments d'appui est variable de manière à assurer l'ajustement de la barrière à des passages de dimensions différentes.Each lateral upright 13 may further comprise bearing elements (not shown) of this amount to a structure which may be a bar of a balustrade, a side of a door frame, or other delimiting an edge of the passage of which the access is intended to be blocked by the barrier. Preferably, the longitudinal dimension of these support elements is variable so as to ensure the adjustment of the barrier to passages of different dimensions.

Chaque élément d'appui est reçu à une de ses extrémités dans un logement 15 prévu à cet effet dans le corps du montant latéral correspondant 13.Each support element is received at one of its ends in a housing 15 provided for this purpose in the body of the corresponding lateral upright 13.

Ce panneau central 12 est relié à chaque montant latéral 13 de manière pivotante par des éléments d'articulation 16 formés ici par des languettes métalliques percées à leurs extrémités.This central panel 12 is connected to each lateral upright 13 pivotally by hinge members 16 formed here by metal tongues pierced at their ends.

Une première partie de chaque élément d'articulation 16 est reçue dans une fente 17 correspondante placée dans un montant latéral 13 correspondant, cette fente 17 débouchant sur le bord intérieur à la barrière de ce montant latéral 13 tandis qu'une deuxième partie de cet élément d'articulation 16 est reçue dans une autre fente placée sur le panneau central 12, ces fentes 17 étant placées en vis-à-vis et les parties des éléments d'articulation 16 étant mobiles en rotation dans leurs logements constitués par ces fentes 17 pour autoriser le mouvement du panneau central 12 par rapport aux montants latéraux 13.A first part of each articulation element 16 is received in a corresponding slot 17 placed in a corresponding lateral upright 13, this slot 17 opening on the inner edge at the barrier of this lateral upright 13 while a second part of this element articulation 16 is received in another slot placed on the central panel 12, these slots 17 being placed facing each other and the parts of the articulation elements 16 being rotatable in their housings formed by these slots 17 for allow the movement of the central panel 12 relative to the lateral uprights 13.

En ce qui concerne la partie supérieure des montants latéraux 13 de cette barrière, chaque fente 17 débouche également sur le sommet du montant latéral 13 correspondant pour permettre à la traverse supérieure du panneau central 12 de se déplacer au moins en partie au-dessus de ces montants latéraux 13 dans une position relevée de ce panneau central lors de l'ouverture de la barrière.With regard to the upper part of the lateral uprights 13 of this barrier, each slot 17 also opens onto the top of the corresponding lateral upright 13 to allow the upper cross member of the central panel 12 to move at least partly above them. side uprights 13 in a raised position of this central panel when opening the barrier.

Chaque montant latéral 13 forme avec ses deux éléments d'articulation 16 et le bord latéral 14 correspondant du panneau central 12, un parallélogramme régulier déformable permettant par un déplacement en translation du panneau central 12 par rapport aux montants latéraux 13 de faire passer la barrière, d'une première position dite de blocage où le panneau central 12 est dans une position abaissée (Figures 4 et 7) à une deuxième position dite de déblocage où le panneau central 12 étant dans une position relevée (Figures 5 et 7) par rapport aux montants latéraux 13, la barrière n'est plus solidaire des structures délimitant le passage à barrer.Each lateral upright 13 forms with its two hinge elements 16 and the corresponding lateral edge 14 of the central panel 12, a deformable regular parallelogram permitting, by translational displacement of the central panel 12 with respect to the lateral uprights 13, to pass the barrier, a first so-called locking position where the central panel 12 is in a lowered position ( Figures 4 and 7 ) at a second unlocking position where the central panel 12 is in a raised position ( Figures 5 and 7 ) relative to the lateral uprights 13, the barrier is no longer integral with the structures defining the passage to be barred.

Il est à noter que lorsque le panneau central 12 se déplace de sa position de déblocage, ou ouverte, à sa position de blocage, encore dite position de fermeture, les montants latéraux 13 se déplacent en sens opposé en s'éloignant du panneau central 12. Ce déplacement des montants latéraux 13 permet de plaquer les bords extérieurs des montants latéraux 13 ou les éléments d'appui portés par ces montants latéraux 13 contre les structures délimitant le passage pour caler en position la barrière de sécurité.It should be noted that when the central panel 12 moves from its unlocking position, or open, to its locking position, still said closed position, the lateral uprights 13 move in opposite directions away from the central panel 12 This displacement of the lateral uprights 13 makes it possible to press the outer edges of the lateral uprights 13 or the bearing elements carried by these lateral uprights 13 against the structures defining the passage to wedge in position the safety barrier.

Toutefois, et pour rendre encore plus sûr le fonctionnement de cette barrière toute en conservant sa simplicité d'utilisation, celle-ci comporte également un moyen de blocage du déplacement d'un des éléments d'articulation 16 lorsque la barrière est dans sa position de fermeture de sorte que le panneau central 12 ne peut être déplacé en translation par rapport aux montants latéraux 13 sans action préalable de l'opérateur pour déverrouiller et maintenir déverrouillé ce moyen de blocage lors du déplacement du panneau central 12 de sa position de fermeture vers sa position d'ouverture.However, and to make the operation of this barrier even safer while retaining its simplicity of use, it also comprises a means of blocking the displacement of one of the articulation elements 16 when the barrier is in its position of closing so that the central panel 12 can not be moved in translation relative to the lateral uprights 13 without the prior action of the operator to unlock and maintain unlocked this locking means during movement of the central panel 12 from its closed position to its opening position.

Ce moyen de blocage qui est ici monté dans la partie supérieure de la barrière comporte d'une part un doigt 18 solidaire du panneau central 12 et d'autre part, un logement 20 destiné à recevoir ce doigt lorsque celui-ci fait saillie du bord latéral 14 correspondant du panneau central 12 dans la position de blocage, ou encore de fermeture, de la barrière, ce logement 20 étant placé dans la partie supérieure du montant latéral 13 portant l'élément d'articulation dont le déplacement est à bloquer.This locking means which is here mounted in the upper part of the barrier comprises firstly a finger 18 secured to the central panel 12 and secondly, a housing 20 for receiving the finger when the latter protrudes from the edge lateral 14 corresponding central panel 12 in the blocking position, or closing, the barrier, this housing 20 being placed in the upper part of the lateral upright 13 carrying the hinge element whose movement is to be blocked.

Le doigt 18 est mobile entre une position rétractée dans laquelle il est placé à distance du bord intérieur 19 du montant latéral 13 correspondant de manière à autoriser le pivotement de l'élément d'articulation 16, et une position dans laquelle il fait saillie du bord latéral 14 correspondant de ce panneau central 12 de manière à être partiellement reçu dans le logement 20 lorsque la barrière est dans sa position de fermeture.The finger 18 is movable between a retracted position in which it is placed at a distance from the inner edge 19 of the corresponding lateral upright 13 so as to allow pivoting of the hinge element 16, and a position in which it projects from the edge lateral 14 corresponding to this central panel 12 so as to be partially received in the housing 20 when the barrier is in its closed position.

Un moyen de rappel 21 tel qu'un ressort assure le rappel du doigt 18 dans sa position dans laquelle il forme saillie du bord latéral 14 du panneau central 12 de sorte que sans action de l'opérateur, le moyen de blocage bloque systématiquement, dans la position de fermeture de la barrière, l'ouverture de celle-ci.A return means 21 such as a spring ensures the return of the finger 18 in its position in which it projects from the lateral edge 14 of the central panel 12 so that without action by the operator, the locking means systematically blocks, in the closing position of the barrier, the opening thereof.

La Figure 6 montre une vue en perspective du corps 22 rigide en matière plastique dans lequel est formé ce logement 20 destiné à recevoir le doigt 18 du moyen de blocage.The Figure 6 shows a perspective view of the rigid body 22 of plastic in which is formed the housing 20 for receiving the finger 18 of the locking means.

Ce corps 22 comprend d'une part des premiers orifices 23 pour le passage de la tige d'organe de fixation et d'autre part, un second orifice 24 pour le passage du doigt 18, ledit second orifice 24 étant en communication avec le logement 20.This body 22 comprises on the one hand first orifices 23 for the passage of the fastener rod and secondly, a second orifice 24 for the passage of the finger 18, said second orifice 24 being in communication with the housing 20.

Une fois l'extrémité au moins du doigt 18 reçue dans ce logement, l'élément d'articulation 16 est bloqué en déplacement. Ce corps 22 comporte également une fente 25 coïncidant avec la fente 17 du montant latéral 13 sur lequel il est monté pour assurer le passage de l'élément d'articulation 16 lors de son déplacement. La partie supérieure de ce corps est également arrondie pour faciliter le passage de la traverse supérieure du panneau central 12 lors du déplacement en translation du panneau central de sa position abaissée vers sa position relevée par rapport aux montants latéraux 13. Ce corps 22 est destiné à être monté dans un évidement réalisé dans le montant latéral 13 correspondant (Figures 3 et 5).Once at least the end of the finger 18 received in this housing, the hinge member 16 is blocked in motion. This body 22 also has a slot 25 coinciding with the slot 17 of the lateral upright 13 on which it is mounted to ensure the passage of the hinge member 16 during its movement. The upper part of this body is also rounded to facilitate the passage of the upper cross member of the central panel 12 during the displacement in translation of the central panel from its lowered position to its raised position relative to the lateral uprights 13. This body 22 is intended for to be mounted in a recess made in the corresponding side post 13 ( Figures 3 and 5 ).

Pour assurer le déblocage de l'élément d'articulation 16, la barrière comporte un dispositif de commande manuel qui est ici un bouton 26 déplaçable le long d'un rail de guidage, ou encore un curseur, ce bouton 26 étant solidaire dudit doigt 18.To ensure the release of the hinge member 16, the barrier comprises a manual control device which is here a button 26 movable along a guide rail, or a slider, the button 26 being secured to said finger 18 .

Ainsi, en agissant sur ce bouton 26, l'opérateur peut manuellement déplacer le doigt 18 entre ses deux positions extrêmes de sorte que celui-ci s'efface au moins partiellement pour libérer l'élément d'articulation 16 dans la position de fermeture de la barrière. L'élément d'articulation 16 étant ainsi libre de pivoter, l'opérateur peut dés lors déplacer librement en translation le panneau central 12 de sa position de fermeture vers sa position d'ouverture.Thus, by acting on this button 26, the operator can manually move the finger 18 between its two extreme positions so that it fades at least partially to release the hinge member 16 in the closed position of the barrier. The hinge member 16 is thus free to rotate, the operator can then move freely in translation the central panel 12 from its closed position to its open position.

Comme représenté sur la Figure 7, si un opérateur tente d'ouvrir la barrière alors qu'un des éléments d'articulation 16 est bloqué, la barrière se déforme entraînant une rotation d'une partie de celle-ci et une accentuation du verrouillage empêchant toute ouverture intempestive de la barrière.As shown on the Figure 7 , if an operator tries to open the barrier while one of the hinge elements 16 is blocked, the barrier is deformed causing a rotation of a portion thereof and an accentuation of the lock preventing unintentional opening of the barrier .

En partant d'une barrière en position de blocage, ou de fermeture, l'opérateur doit donc réaliser deux étapes successives pour assurer l'ouverture de la barrière représentée sur les Figures 3 à 7 :

  • 1) l'actionnement du dispositif de commande manuel 26 pour libérer l'élément d'articulation 16 bloqué par le moyen de blocage,
  • 2) le maintien de l'appui sur le bouton 26 pour contrer la force de rappel du ressort 21 et assurer ainsi le maintien du doigt 18 dans sa position rétractée, et le soulèvement simultané du panneau central 12 pour assurer son déplacement en translation par rapport aux montants latéraux 13.
Starting from a barrier in the locked position, or closing, the operator must therefore perform two successive steps to ensure the opening of the barrier represented on the Figures 3 to 7 :
  • 1) actuating the manual control device 26 to release the hinge member 16 blocked by the blocking means,
  • 2) maintaining the support on the button 26 to counter the return force of the spring 21 and thus ensure the retention of the finger 18 in its retracted position, and the simultaneous lifting of the central panel 12 to ensure its displacement in translation relative to the lateral uprights 13.

Bien entendu, l'opérateur n'a aucune obligation de maintenir le bouton 26 pendant tout le déplacement du panneau central 12 pour arriver à l'ouverture de la barrière. Le doigt 18 étant solidaire de la traverse supérieure du panneau central, il suffit que celle-ci ait été amenée au-dessus du logement 20 monté sur le montant latéral 13.Of course, the operator has no obligation to maintain the button 26 during the entire displacement of the central panel 12 to arrive at the opening of the barrier. The finger 18 being integral with the upper cross member of the central panel, it is sufficient that it has been brought above the housing 20 mounted on the lateral upright 13.

Les Figures 8 à 11 montrent une barrière de sécurité selon un autre mode de réalisation de la présente invention. Les références sur les Figures 8 à 11 identiques à celles des Figures 3 à 7 représentent les mêmes objets, lesquels ne seront pas décrits de nouveau ci-après.The Figures 8 to 11 show a safety barrier according to another embodiment of the present invention. References on Figures 8 to 11 identical to those of Figures 3 to 7 represent the same objects, which will not be described again below.

La barrière montrée sur les Figures 8 à 11 se distingue de celle représentée sur les Figures 3 à 7 en ce que le doigt 18 du moyen de blocage de l'élément d'articulation 16 est relié à un bouton 27 se déplaçant dans un rail de guidage 28 placé dans la partie supérieure d'un corps 29 présentant deux ailes latérales 30, 31 de sorte qu'il a une section en forme de U. Ce corps 29 vient ainsi recouvrir la traverse supérieure 12 en étant reçu dans un évidement 32 réalisé dans celle-ci de sorte qu'une fois ce corps 29 monté sur la traverse, la surface extérieure de chaque aile 30, 31 de corps est placé de niveau ou sensiblement de niveau avec la surface extérieure de la traverse supérieure 12 formant ainsi une surface continue ou sensiblement continue.The barrier shown on Figures 8 to 11 differs from that shown in the Figures 3 to 7 in that the finger 18 of the locking means of the articulation element 16 is connected to a button 27 moving in a guide rail 28 placed in the upper part of a body 29 having two lateral wings 30, 31 of so that it has a U-shaped section. This body 29 thus covers the upper cross member 12 being received in a recess 32 formed therein so that once the body 29 mounted on the cross, the surface the outer surface of each body flange 30, 31 is placed at or substantially level with the outer surface of the upper cross member 12 thus forming a continuous or substantially continuous surface.

De plus, l'axe de pivotement 33 de l'élément d'articulation 16 qui est également ici une languette, est confondu avec les axes principaux des orifices 34, 35 du corps 29 et de la traverse supérieure 12 assurant le passage de la tige de l'organe de fixation du corps 29 avec son logement 32 sur la traverse supérieure 12. Ce mode de réalisation assure avantageusement la conservation de la distance séparant le bord latéral du panneau central 12 du montant latéral 13 correspondant, garantissant ainsi le bon fonctionnement de la barrière de sécurité.In addition, the pivot axis 33 of the hinge member 16 which is also a tongue here, is coincident with the main axes of the orifices 34, 35 of the body 29 and the upper cross member 12 ensuring the passage of the rod the fixing member of the body 29 with its housing 32 on the upper crosspiece 12. This embodiment advantageously ensures the preservation of the distance separating the lateral edge of the central panel 12 of the corresponding side post 13, thus ensuring the proper functioning of the security barrier.

Chaque montant latéral 13 comporte par ailleurs dans sa partie inférieure et sur son bord intérieur à la barrière, une échancrure 36 destinée à permettre le déplacement de la traverse inférieure 37 lors du passage du panneau central 12 entre sa position abaissée et sa position relevée. Dans cette dernière position, les extrémités de la traverse inférieure 37 viennent en butée contre ces échancrures 36 pour stopper le déplacement du panneau central 12.Each side upright 13 also has in its lower part and on its inner edge to the barrier, a recess 36 intended to allow the movement of the lower cross member 37 during the passage of the central panel 12 between its lowered position and its raised position. In this latter position, the ends of the lower cross member 37 abut against these notches 36 to stop the displacement of the central panel 12.

La barrière comporte encore sur chacun de ses montants latéraux 13, deux éléments d'appui 38 constitués d'une tige filetée portant à son extrémité libre une surface d'appui du type disque, destinés à assurer l'appui de la barrière avec la structure délimitant le passage à barrer.The barrier still has on each of its lateral uprights 13, two support elements 38 consisting of a threaded rod carrying at its free end a support surface of the disc type, intended to ensure the support of the barrier with the structure delimiting the passage to be barred.

Des coupelles 39 destinées à être montées sur la structure délimitant le passage à bloquer, forment des butées pour empêcher le soulèvement de la barrière ainsi que son déplacement hors du plan passant par le panneau central de la barrière.Cups 39 intended to be mounted on the structure defining the passage to be blocked, form stops to prevent the lifting of the barrier and its movement out of the plane passing through the central panel of the barrier.
