Description

L'invention a trait à un dispositif pour le maintien de l'extrémité latérale d'une lame de tablier de volet roulant à l'intérieur d'une coulisse latérale que comporte ledit volet roulant et dans laquelle ladite extrémité est à même de se déplacer. Cette invention est, encore, relative à une lame de tablier de volet roulant équipée d'un tel dispositif ainsi qu'à un volet roulant comportant une telle lame.The invention relates to a device for holding the lateral end of a rolling shutter apron blade inside a lateral slide which comprises said shutter and in which said end is able to move . This invention is, again, relating to a rolling shutter deck blade equipped with such a device and to a roller shutter comprising such a blade.

L'invention concerne le domaine de la fabrication des volets roulants et, plus particulièrement, celui des accessoires venant équiper un tel volet roulant en vue d'en améliorer les performances.The invention relates to the field of the manufacture of shutters and, more particularly, that of the accessories coming to equip such a shutter to improve performance.

L'on connaît, d'ores et déjà, des volets roulant comportant un arbre d'entraînement sur lequel s'enroule et à partir duquel se déroule un tablier constitué par une juxtaposition de lames reliées entre elles par le biais de moyens d'articulation. Ce volet roulant comporte, encore, des coulisses latérales dans lesquelles se déplacent les extrémités latérales des lames constituant le tablier, ceci lors des manoeuvres de déploiement et repliement de ce tablier.Rolling shutters are already known, including a drive shaft on which is wound and from which takes place an apron constituted by a juxtaposition of blades interconnected by means of articulation means. . This roller shutter comprises, again, lateral slides in which move the lateral ends of the blades constituting the deck, this during the deployment maneuvers and folding of this deck.

A ce propos, il convient d'observer que les lames de ce tablier, plus particulièrement lorsqu'elles sont réalisées en un matériau synthétique comme du PVC, présentent une certaine souplesse et une certaine flexibilité de sorte que ces lames ont tendance à se déformer pour former un ventre, ceci sous l'effet d'une force exercée dans une direction sensiblement perpendiculaire au tablier. Une telle force peut être exercée par un vent plus ou moins violent, notamment par une bourrasque d'une tempête, ou encore par un malfaiteur qui tente de pénétrer dans une habitation par effraction.In this regard, it should be noted that the blades of this deck, more particularly when they are made of a synthetic material such as PVC, have a certain flexibility and flexibility so that these blades tend to deform for to form a belly, this under the effect of a force exerted in a direction substantially perpendicular to the apron. Such a force can be exerted by a more or less violent wind, notably by a gust of a storm, or by a malefactor who tries to break into a house.

Aussi, sous l'effet d'une telle force, les lames du tablier subissent une contrainte qui a tendance à extraire ces lames hors des coulisses dans lesquelles elles sont engagées. Ce phénomène est, évidemment, encore plus perceptible dans le cadre de tabliers de grandes largeurs comme ceux équipant des baies vitrées ou analogue.Also, under the effect of such a force, the apron blades undergo a stress that tends to extract these blades out of the wings in which they are engaged. This phenomenon is, obviously, even more noticeable in the context of large aprons such as those equipping windows or the like.

Afin de remédier à ces inconvénients, il a, d'ores et déjà, été imaginé d'augmenter la profondeur des coulisses ainsi que la profondeur d'engagement des lames dans ces coulisses. Ceci ne permet que de remédier partiellement au problème sachant que, sous l'effet d'une force exercée sur le tablier, ce dernier subira toujours une déformation qui ne peut être acceptée, notamment en raison des dimensions limitées (voire ajustées à celles du tablier sans déformation) du caisson de volet roulant dans lequel ce tablier est destiné à être enroulé.In order to overcome these disadvantages, it has already been devised to increase the depth of the slides and the depth of engagement of the blades in these slides. This only makes it possible to partially remedy the problem knowing that, under the effect of a force exerted on the deck, the latter will always undergo a deformation which can not be accepted, in particular because of the limited dimensions (even adjusted to those of the deck without deformation) of the shutter box in which this apron is intended to be wound.

De plus, l'augmentation de la profondeur des coulisses nécessite une augmentation de la largeur de ces coulisses ce qui, d'une part, est considéré comme particulièrement inesthétique et, d'autre part, empiète sur la surface vitrée d'une fenêtre équipée d'un tel volet roulant.In addition, the increase in the depth of the slides requires an increase in the width of these slides which, on the one hand, is considered particularly unsightly and, on the other hand, encroaches on the glass surface of a window equipped such a shutter.

Dans la demande de brevet FR-2.749.880 il est décrit un dispositif pour le maintien de l'extrémité latérale d'une lame de tablier de volet roulant à l'intérieur d'une coulisse latérale que comporte ledit volet roulant et dans laquelle ladite extrémité de lame est à même de se déplacer. Ce dispositif se présente sous la forme d'un embout destiné, d'une part, à être rendu solidaire de l'extrémité latérale d'une lame du tablier et, d'autre part, à venir se positionner au moins en partie à l'intérieur d'une coulisse. Cet embout comporte, d'une part, au moins un levier monté en basculement sur ledit embout, ceci entre une première position dans laquelle un tel levier s'étend latéralement par rapport audit embout pour, en cas de force exercée sur la lame équipée de l'embout et ayant tendance à extraire cette lame hors de sa coulisse, coopérer avec une butée d'arrêt que comporte intérieurement ladite coulisse en vue d'un maintien de l'extrémité latérale de cette lame dans cette coulisse et au moins une seconde position dans laquelle un tel levier est escamoté par rapport audit embout.In the request for FR-2,749,880 there is described a device for holding the lateral end of a rolling shutter apron blade inside a lateral slide which comprises said shutter and in which said blade end is able to move. This device is in the form of a tip intended, on the one hand, to be secured to the lateral end of an apron blade and, secondly, to come to be positioned at least in part to the inside a slide. This tip comprises, on the one hand, at least one lever mounted on said tip, this between a first position in which such a lever extends laterally with respect to said tip for, in case of force exerted on the blade equipped with the tip and having tendency to extract this blade out of its slide, to cooperate with a stop which internally comprises said slide in order to maintain the lateral end of this slide in this slide and at least a second position in which such a lever is retracted relative to said tip.

A ce propos, on observera que ledit levier est monté en libre rotation autour d'un axe sur ledit embout et est soumis à son propre poids. Ce levier est conçu en sorte de présenter un décalage entre la position de son centre de gravité et de son axe de rotation de manière à permettre le basculement de ce levier sous l'effet de son propre poids en direction de la première position d'extension latérale susmentionnée. Un tel dispositif s'avère, en fait, peu efficace et particulièrement sujet au grippage de sorte que le basculement naturel du levier, sous l'effet de son propre poids et en direction de la première position d'extension, reste particulièrement aléatoire et aucunement systématique.In this regard, it will be observed that said lever is mounted in free rotation about an axis on said tip and is subjected to its own weight. This lever is designed so as to have a shift between the position of its center of gravity and its axis of rotation so as to allow the tilting of the lever under the effect of its own weight in the direction of the first extended position mentioned above. Such a device proves, in fact, inefficient and particularly subject to seizure so that the natural tilting of the lever, under the effect of its own weight and towards the first extended position, remains particularly random and in no way systematic.

La présente invention se veut à même de remédier aux inconvénients des volets roulants de l'état de la technique.The present invention is intended to overcome the disadvantages of rolling shutters of the state of the art.

A cet effet, l'invention concerne un dispositif pour le maintien de l'extrémité latérale d'une lame de tablier de volet roulant à l'intérieur d'une coulisse latérale que comporte ledit volet roulant et dans laquelle ladite extrémité de lame est à même de se déplacer. Ce dispositif se présente sous la forme d'un embout destiné, d'une part, à être rendu solidaire de l'extrémité latérale d'une lame du tablier et, d'autre part, à venir se positionner au moins en partie à l'intérieur d'une coulisse. Cet embout comporte au moins un levier monté en basculement sur ledit embout, ceci entre une première position dans laquelle un tel levier s'étend latéralement par rapport audit embout pour, en cas de force exercée sur la lame équipée de l'embout et ayant tendance à extraire cette lame hors de sa coulisse, coopérer avec une butée d'arrêt que comporte intérieurement ladite coulisse en vue d'un maintien de l'extrémité latérale de cette lame dans cette coulisse et au moins une seconde position dans laquelle un tel levier est escamoté par rapport audit embout. Ce dispositif est caractérisé par le fait que l'embout comporte des moyens de rappel d'un tel levier dans ladite première position dans laquelle un tel levier s'étend latéralement par rapport à l'embout.For this purpose, the invention relates to a device for holding the lateral end of a rolling shutter apron blade inside a lateral slide that comprises said shutter and in which said blade end is at even to move. This device is in the form of a tip intended, on the one hand, to be secured to the lateral end of an apron blade and, secondly, to come to be positioned at least in part to the inside a slide. This endpiece comprises at least one lever pivotally mounted on said endpiece, this between a first position in which such a lever extends laterally with respect to said end piece, in case of force exerted on the blade equipped with the endpiece and having a tendency to extract this blade out of its slide, to cooperate with a stop which internally comprises said slide in order to maintain the lateral end of this blade in this slide and at least a second position in which such a lever is retracted relative to said nozzle. This device is characterized in that the tip comprises return means of such a lever in said first position in which such a lever extends laterally relative to the tip.

L'invention concerne, encore, une lame de tablier de volet roulant présentant des extrémités latérales destinées à se déplacer dans des coulisses latérales que comporte un tel volet roulant et recevant, au niveau de l'une au moins de ses extrémités latérales, un dispositif de maintien conforme à celui susmentionné.The invention also relates to a rolling shutter apron blade having lateral ends intended to move in lateral wings that comprises such a shutter and receiving, at at least one of its lateral ends, a device in keeping with that mentioned above.

Cette invention concerne, également, un volet roulant comportant, d'une part, un tablier constitué par un assemblage de lames, notamment articulées entre elles, et présentant, chacune, des extrémités latérales, d'autre part, des coulisses latérales à l'intérieur desquelles se déplacent les extrémités latérales des lames du tablier et, d'autre part encore et au niveau d'au moins une extrémité d'au moins une lame du tablier, un dispositif de maintien conforme à celui susmentionné.This invention also relates to a roller shutter comprising, on the one hand, an apron consisting of an assembly of blades, in particular articulated between them, and each having lateral ends, on the other hand, lateral slides to the inside which move the lateral ends of the apron blades and, secondly and at the level of at least one end of at least one deck blade, a holding device according to the aforementioned.

Les avantages de la présente invention consistent en ce que l'embout, lorsqu'il est positionné à l'intérieur d'une coulisse, comporte au moins un levier qui s'étend latéralement par rapport à cet embout et qui est conçu apte, lorsqu'une force est exercée sur une lame équipée de cet embout et ayant tendance à extraire cette lame hors de sa coulisse, à coopérer avec une butée d'arrêt que comporte intérieurement ladite coulisse en vue d'un maintien de l'extrémité latérale de cette lame dans cette coulisse.The advantages of the present invention consist in that the endpiece, when positioned inside a slide, comprises at least one lever which extends laterally with respect to this endpiece and which is designed suitable, when a force is exerted on a blade equipped with this endpiece and having a tendency to extract this blade out of its slide, to cooperate with a stop which internally comprises said slide in order to maintain the lateral end of this blade in this slider.

De manière avantageuse, le levier de cet embout est susceptible d'adopter une position escamotée par rapport à cet embout, plus particulièrement lorsque la lame équipée de cet embout pénètre dans la coulisse ou en sort, voire lorsque les lames sont superposées au sein d'un enroulement du tablier à l'intérieur du caisson.Advantageously, the lever of this tip is likely to adopt a retracted position relative to this tip, more particularly when the blade equipped with this nozzle enters the slide or leaves or even when the blades are superimposed within a winding of the apron inside the box.

La présente invention concerne le domaine de la fabrication des volets roulants destinés à équiper une porte, une fenêtre ou analogue.The present invention relates to the field of the manufacture of shutters intended to equip a door, a window or the like.

Un tel volet roulant 1 comporte, usuellement, un caisson 2 à l'intérieur duquel est monté en rotation un arbre sur lequel s'enroule et à partir duquel se déroule le tablier 3 d'un tel volet roulant 1. Un tel tablier 3 est constitué par une juxtaposition de lames 4 reliées entre elles par le biais de moyens d'articulation 5 et présentant, chacune 4, deux extrémités latérales 6.Such a shutter 1 comprises, usually, a box 2 inside which is mounted in rotation a shaft on which rolls and from which takes place the deck 3 of such a shutter 1. Such apron 3 is constituted by a juxtaposition of blades 4 connected to each other by means of articulation means 5 and having, each 4, two lateral ends 6.

Ce volet roulant 1 comporte, de plus, des coulisses latérales 7, surmontées par ledit caisson 2 et débouchant à l'intérieur de ce dernier 2 (figures 5 à 8). C'est, plus particulièrement, à l'intérieur de ces coulisses latérales 7 que se déplacent les extrémités latérales 6 des lames 4 du tablier 3, ceci lors des manoeuvres de déploiement et repliement de ce tablier 3.This roller shutter 1 has, in addition, lateral slides 7, surmounted by said box 2 and opening into the latter 2 ( Figures 5 to 8 ). It is, more particularly, within these lateral slides 7 that the lateral ends 6 of the blades 4 of the deck 3 move, this during the deployment and folding maneuvers of this deck 3.

A ce propos, on observera que le tablier 3 d'un tel volet roulant 1 peut être soumis à une force, notamment résultant d'un vent ou d'une tentative d'effraction, s'exerçant de manière sensiblement perpendiculaire au plan de ce tablier 3 et se traduisant par une force F tendant à extraire l'extrémité latérale 6 d'une lame 4 hors de la coulisse latérale 7 dans laquelle cette lame 4 est positionnée.In this regard, it will be observed that the deck 3 of such a shutter 1 may be subjected to a force, in particular resulting from a wind or an attempted break-in, acting in a manner substantially perpendicular to the plane of this apron 3 and resulting in a force F tending to extract the lateral end 6 of a blade 4 out of the lateral slide 7 in which the blade 4 is positioned.

L'invention concerne, alors, un dispositif 8 pour le maintien de l'extrémité latérale 6 d'une lame 4 de tablier 3 de volet roulant 1 à l'intérieur d'une coulisse latérale 7 que comporte ledit volet roulant 1 et dans laquelle ladite extrémité 6 de lame 4 est à même de se déplacer.The invention relates, then, to a device 8 for holding the lateral end 6 of a blade 4 of roller shutter apron 3 inside a lateral slide 7 that comprises said shutter 1 and in which said blade end 4 is able to move.

Tel que visible sur les figures en annexe, un tel dispositif 8 se présente sous la forme d'un embout 9 destiné, d'une part, à être rendu solidaire de l'extrémité latérale 6 d'une lame 4 du tablier 3 et, d'autre part, à venir se positionner au moins en partie à l'intérieur d'une coulisse 7.As can be seen in the appended figures, such a device 8 is in the form of a nozzle 9 intended, on the one hand, to be secured to the lateral end 6 of a blade 4 of the apron 3 and, on the other hand, to be positioned at least partially inside a slide 7.

Cet embout 9 comporte au moins un levier 10, 10' monté en basculement sur ledit embout 9, ceci entre une première position (notamment figures 1, 1a, 3, 4, 5, 8, 9, 13 et 14) et au moins une seconde position (notamment figure 2, 2a, 10, 11 et 15).This endpiece 9 comprises at least one lever 10, 10 'pivotally mounted on said endpiece 9, this between a first position (in particular FIGS. 1, 1a, 3, 4 , 5 , 8 , 9 , 13 and 14 ) and at least one second position (especially figure 2, 2a , 10, 11 and 15 ).

A ce propos, on observera que le dispositif 8 conforme à la présente invention est conçu en sorte que le basculement d'un tel levier 10, 10' s'opère autour d'un axe s'étendant de manière sensiblement parallèle au plan du tablier 3, voire encore de manière sensiblement parallèle à la direction dans laquelle s'étend la lame 4 recevant ce dispositif 8.In this regard, it will be observed that the device 8 according to the present invention is designed so that the tilting of such a lever 10, 10 'operates around an axis extending substantially parallel to the plane of the apron 3, or even substantially parallel to the direction in which extends the blade 4 receiving the device 8.

Dans ladite première position, un tel levier 10, 10' s'étend latéralement par rapport audit embout 9 pour, en cas de force F exercée sur la lame 4 équipée de l'embout 9 (ou sur le tablier 3 comportant une telle lame 4) et ayant tendance à extraire cette lame 4 hors de sa coulisse 7, coopérer avec une butée d'arrêt 11, 11' que comporte intérieurement ladite coulisse 7, ceci en vue d'un maintien de l'extrémité latérale 6 de cette lame 4 dans cette coulisse 7. Tel que visible dans les figures en annexe, lorsqu'un tel levier 10, 10' se trouve dans cette première position, ce levier 10, 10' est, au moins en partie, déployé par rapport audit embout 9.In said first position, such a lever 10, 10 'extends laterally relative to said nozzle 9 to, in case of force F exerted on the blade 4 equipped with the nozzle 9 (or on the apron 3 comprising such a blade 4) and having a tendency to extract this blade 4 out of its slide 7, to cooperate with a stopper 11, 11 'which internally comprises said slide 7, this in order to maintain the lateral end 6 of this blade 4 in this slide 7. As can be seen in the appended figures, when such a lever 10, 10 'is in this first position, this lever 10, 10' is, at least in part, deployed by report to said tip 9.

Dans ladite ou lesdites secondes positions, un tel levier 10, 10' est au moins en partie escamoté par rapport audit embout 9, notamment à l'intérieur de celui-ci 9. Un tel levier 10, 10' se retrouve dans une telle position escamotée, notamment lors de la pénétration dans une coulisse 7 (figures 6, 7) ou lors de la sortie hors de cette coulisse 7, de la lame 4 équipée d'un embout 9, plus particulièrement lors des manoeuvres de déploiement et de repliement du tablier 3.In said second position or positions, such a lever 10, 10 'is at least partially retracted relative to said nozzle 9, in particular inside thereof 9. Such a lever 10, 10' is found in such a position retracted, especially when penetrating a slide 7 ( figures 6 , 7 ) or when exiting from this slide 7, the blade 4 equipped with a nozzle 9, particularly during deployment and folding maneuvers apron 3.

Selon un premier type de réalisation non représenté, l'embout 9 du dispositif 8 de maintien peut comporter un seul levier 10.According to a first type of embodiment not shown, the tip 9 of the holding device 8 may comprise a single lever 10.

Cependant et selon un type de réalisation préféré de l'invention, l'embout 9 du dispositif 8 de maintien comporte deux leviers 10, 10' montés en basculement sur ledit embout 9 et conçus aptes à s'étendre de part et d'autre de cet embout 9, ceci dans une première position dans laquelle ces leviers 10, 10' sont destinés à coopérer, chacun 10 ; 10', avec une butée d'arrêt 11 ; 11' que comporte intérieurement une coulisse 7, plus particulièrement de part et d'autre d'une ouverture 12 traversée par la lame 4 recevant le dispositif de maintien 8.However, according to a preferred embodiment of the invention, the tip 9 of the holding device 8 comprises two levers 10, 10 'pivotally mounted on said tip 9 and designed to extend on either side of this tip 9, this in a first position in which these levers 10, 10 'are intended to cooperate, each 10; 10 ', with a stopper 11; 11 'internally comprises a slide 7, more particularly on either side of an opening 12 traversed by the blade 4 receiving the holding device 8.

Un premier mode de réalisation illustré figures 1 à 8 consiste en ce que ces deux leviers 10, 10' sont définis au niveau d'une même pièce 13 montée en basculement sur ledit embout 9, plus particulièrement à proximité ou au niveau de l'extrémité de cet embout 9.A first illustrated embodiment Figures 1 to 8 consists in that these two levers 10, 10 'are defined at the same part 13 mounted in tilting on said tip 9, more particularly near or at the end of this tip 9.

Un second et un troisième mode de réalisation consiste en ce que ces deux leviers 10, 10' sont indépendants l'un 10 de l'autre 10' et sont montés, chacun, en basculement sur ledit embout 9, plus particulièrement à proximité ou au niveau de l'extrémité de cet embout 9.A second and a third embodiment consists in that these two levers 10, 10 'are independent of one another 10' and are each mounted in tilting on said tip 9, more particularly near or at level of the end of this tip 9.

A ce propos et tel qu'illustré figures 9 à 16, un tel levier 10, 10' peut être défini au niveau d'un crochet 26, 26' que comporte le dispositif de maintien 8 et qui est monté en basculement sur ledit embout 9, ceci entre, d'une part, une première position (position déployée) dans laquelle le levier 10, 10' d'un tel crochet 26, 26' s'étend latéralement par rapport audit embout 9 (figures 9, 13 et 14) et, d'autre part, au moins une seconde position (figures 10, 11 et 15) dans laquelle le levier 10, 10' d'un tel crochet 26, 26' est escamoté par rapport à cet embout 9.In this respect and as illustrated Figures 9 to 16 , such a lever 10, 10 'can be defined at a hook 26, 26' that includes the holding device 8 and which is pivotally mounted on said nozzle 9, this enters, on the one hand, a first position (deployed position) in which the lever 10, 10 'of such a hook 26, 26' extends laterally with respect to said end piece 9 ( figures 9 , 13 and 14 ) and, on the other hand, at least a second position ( Figures 10, 11 and 15 ) in which the lever 10, 10 'of such a hook 26, 26' is retracted relative to this nozzle 9.

Plus particulièrement et tel que visible sur les figures 9 à 16, un tel crochet 26 comporte, d'une part, une première partie 27 au niveau de laquelle est défini un tel levier 10 et, d'autre part, une seconde partie 28, se situant dans la prolongement de ladite première partie 27, et orientée, de préférence, de manière sensiblement perpendiculaire à cette première partie 27. Cette seconde partie 28 s'étend, sensiblement, selon l'axe de basculement du crochet 26 (donc du levier 10) sur l'embout 9 et est rendue solidaire de cet embout 9 par le biais de moyens autorisant un tel basculement.More particularly and as visible on the Figures 9 to 16 such a hook 26 comprises, on the one hand, a first part 27 at which said lever 10 is defined and, on the other hand, a second part 28 situated in the extension of said first part 27, and oriented, preferably, substantially perpendicularly to this first portion 27. This second portion 28 extends substantially along the axis of tilting of the hook 26 (and therefore the lever 10) on the tip 9 and is secured to this tip 9 by means allowing such a tilting.

A ce propos, on observera que les moyens aptes à rendre un tel crochet 26 solidaire de l'embout 9 sont constitués par des moyens 29 de réception d'un tel crochet 26, plus particulièrement des moyens 29 de réception de ladite seconde partie 28 d'un tel crochet 26, et que comporte ledit embout 9.In this regard, it will be observed that the means capable of rendering such a hook 26 integral with the end piece 9 are constituted by means 29 for receiving such a hook 26, more particularly means 29 for receiving said second part 28. such a hook 26, and that includes said tip 9.

De tels moyens de réception 29 sont conçus aptes à autoriser le basculement susmentionné d'un tel crochet 26 par rapport audit embout 9 et peuvent être constitués par un logement (notamment sous la forme d'une rainure) à l'intérieur duquel vient se positionner au moins en partie ce crochet 26, plus particulièrement, la seconde partie 28 de ce crochet 26.Such receiving means 29 are designed to allow the aforementioned tilting of such a hook 26 relative to said nozzle 9 and may be constituted by a housing (in particular in the form of a groove) within which is positioned at least in part this hook 26, more particularly, the second part 28 of this hook 26.

De plus et tel que visible sur les figures 9 à 16, un tel crochet 26 comporte, au niveau de l'extrémité libre de ladite seconde partie 28, un retour 30 destiné à coopérer avec un rebord d'accrochage que comporte ledit embout 9, ceci au moins dans la première position du levier 10, 10' d'un tel crochet 26 (position déployée) dans laquelle un tel levier 10, 10' est susceptible de coopérer avec une butée d'arrêt 11, 11'.Moreover and as visible on the Figures 9 to 16 , such a hook 26 comprises, at the free end of said second portion 28, a return 30 intended to cooperate with a hooking flange that comprises said tip 9, this at least in the first position of the lever 10, 10 of such a hook 26 (extended position) in which such a lever 10, 10 'is capable of cooperating with a stopper 11, 11'.

Une telle coopération permet de maintenir ledit crochet 26 sur l'embout 9 et d'éviter son arrachage en cas d'accrochage du levier 10, 10' de ce crochet 26 sur une butée d'arrêt 11, 11'.Such cooperation makes it possible to hold said hook 26 on the end piece 9 and to prevent it being pulled in the event of attachment of the lever 10, 10 'of this hook 26 to a stopper 11, 11'.

Une autre caractéristique de cet embout 9 consiste en ce qu'il comporte au moins un logement 14, 14', notamment pour la réception d'au moins un levier 10, 10', et à l'intérieur duquel vient, au moins en partie, s'effacer un tel levier 10, 10' en position d'escamotage de ce dernier 10, 10' (figures 2, 2a, 10, 11 et 15).Another feature of this nozzle 9 is that it comprises at least one housing 14, 14 ', in particular for receiving at least one lever 10, 10', and inside which comes, at least in part , erase such a lever 10, 10 'in the retracted position of the latter 10, 10' ( Figures 2, 2a , 10, 11 and 15 ).

Tel que visible sur les figures 1, 1a, 2 et 2a, c'est, plus particulièrement, à l'intérieur d'un tel logement 14 qu'est, au moins en partie, implantée la pièce 13 au niveau de laquelle sont définis les deux leviers 10, 10' correspondant au premier mode de réalisation du dispositif de maintien 8 selon l'invention.As visible on the Figures 1, 1a, 2 and 2a it is, more particularly, within such a housing 14 that is at least partially implanted the part 13 at which are defined the two levers 10, 10 'corresponding to the first embodiment of the holding device 8 according to the invention.

Ledit embout 9 peut, de plus, être conçu en sorte que cette pièce 13 vienne intégralement s'effacer à l'intérieur de ce logement 14 (figures 2, 2a), plus particulièrement en position d'escamotage du ou des leviers 10, 10'.Said end piece 9 may, in addition, be designed so that this part 13 comes completely to fade inside this accommodation 14 ( Figures 2, 2a ), more particularly in the retracted position of the lever or levers 10, 10 '.

Cependant et tel que visible sur les figures 10, 11 et 15 correspondant aux second et troisième modes de réalisation du dispositif de maintien 8 selon l'invention, c'est, plus particulièrement, à l'intérieur d'un tel logement 14, 14' que le levier 10, 10', constitué par ladite première partie 27 que comporte un crochet 26, 26', vient, au moins en partie, s'effacer, ceci en position d'escamotage d'un tel levier 10, 10'.However and as visible on the Figures 10, 11 and 15 corresponding to the second and third embodiments of the holding device 8 according to the invention, it is, more particularly, inside such a housing 14, 14 'that the lever 10, 10', constituted by said first part 27 that includes a hook 26, 26 ', comes, at least partly, fade, this in the retracted position of such a lever 10, 10'.

A ce propos, on observera qu'un tel logement 14, 14' peut être conçu en sorte de pouvoir recevoir un tel levier 10, 10' dans deux positions d'escamotage (figure 10 et figure 11) dans lesquelles un tel levier 10, 10' peut être positionné de part (figures 10 et 15) et d'autre (figure 11) d'une première position (position déployée visibles figures 9, 13 et 14) d'un tel levier 10, 10', plus particulièrement à + ou - 90° d'une telle position déployée.In this regard, it will be observed that such a housing 14, 14 'can be designed so as to be able to receive such a lever 10, 10' in two retracted positions ( Figure 10 and Figure 11 ) in which such a lever 10, 10 'can be positioned from figures 10 and 15 ) and other ( figure 11 ) a first position (visible deployed position figures 9 , 13 and 14 ) of such a lever 10, 10 ', more particularly at + or - 90 ° of such an extended position.

Selon une autre caractéristique du dispositif 8 selon l'invention, l'embout 9 comporte, encore, des moyens 15 de rappel d'un tel levier 10 dans ladite première position dans laquelle un tel levier 10 s'étend latéralement par rapport à l'embout 9 (position déployée).According to another characteristic of the device 8 according to the invention, the nozzle 9 further comprises means 15 for returning such a lever 10 to said first position in which such a lever 10 extends laterally with respect to the tip 9 (extended position).

Selon un premier type de réalisation de l'invention illustré figures 1 à 11 et correspondant aux premier et second modes de réalisation de l'invention, de tels moyens de rappel 15 sont définis au niveau de l'embout 9 et sont constitués par un doigt élastique 16 conçu pour exercer, sur au moins un levier 10, 10' ou sur au moins un crochet 26 comportant un tel levier 10, 10', une force apte à provoquer le basculement d'un tel levier 10, 10' dans ladite première position dans laquelle un tel levier 10, 10' s'étend latéralement par rapport à l'embout 9 (position déployée).According to a first embodiment of the illustrated invention Figures 1 to 11 and corresponding to the first and second embodiments of the invention, such return means 15 are defined at the tip 9 and are constituted by an elastic finger 16 designed to exert, on at least one lever 10, 10 ' or on at least one hook 26 comprising such a lever 10, 10 ', a force capable of causing the tilting of such a lever 10, 10' in said first position in which such a lever 10, 10 'extends laterally relative to the tip 9 (extended position).

En fait et tel que visible sur les figures 1 à 8 correspondant au premier mode de réalisation du dispositif de maintien 8 selon l'invention, un tel doigt élastique 16 est conçu pour exercer une telle force sur la pièce 13 au niveau de laquelle sont définis les leviers 10, 10'.In fact and as visible on the Figures 1 to 8 corresponding to the first embodiment of the holding device 8 according to the invention, such an elastic finger 16 is designed to exert such force on the part 13 at which the levers 10, 10 'are defined.

Cependant et tel que visible figures 9 à 11 correspondant au second mode de réalisation du dispositif de maintien 8 selon l'invention, un tel doigt élastique 16 est conçu pour exercer une telle force sur le crochet 26, plus particulièrement sur une portion 31 que présente la seconde partie 28 de ce crochet 26 et qui est excentrée par rapport à l'axe de basculement du levier 10, 10' de ce crochet 26 passant, précisément, par ladite seconde partie 28 de ce crochet 26.However and as visible Figures 9 to 11 corresponding to the second embodiment of the holding device 8 according to the invention, such an elastic finger 16 is designed to exert such a force on the hook 26, more particularly on a portion 31 that has the second portion 28 of the hook 26 and which is eccentric with respect to the axis of tilting of the lever 10, 10 'of this hook 26 passing, precisely, by said second part 28 of this hook 26.

Cette portion 31 excentrée par rapport à l'axe de basculement du levier 10, 10' de ce crochet 26 est, en fait, conçue pour coopérer avec les moyens de rappel 15 (doigt élastique 16) d'un tel levier 10, 10' dans ladite première position (position déployée) dans laquelle un tel levier 10, 10' s'étend latéralement par rapport à l'embout 9.This portion 31 eccentric with respect to the tilting axis of the lever 10, 10 'of this hook 26 is, in fact, designed to cooperate with the biasing means 15 (elastic finger 16) of such a lever 10, 10' in said first position (extended position) in which such a lever 10, 10 'extends laterally with respect to the end piece 9.

Tel que visible sur les figures 9 à 12, cette portion excentrée 31 présente une courbure orientée dans une direction opposée à celle dans laquelle s'étend le levier 10, 10'.As visible on the Figures 9 to 12 this eccentric portion 31 has a curvature oriented in a direction opposite to that in which the lever 10, 10 'extends.

En fait, la présence de cette portion excentrée 31 permet au crochet 26 d'adopter la forme d'un vilebrequin sur lequel le doigt élastique 16 exerce en permanence une force permettant, avantageusement et en permanence, de ramener un tel crochet 26 dans une position déployée (première position du ou des leviers 10, 10').In fact, the presence of this eccentric portion 31 allows the hook 26 to adopt the shape of a crankshaft on which the elastic finger 16 permanently exerts a force advantageously and permanently, to bring such a hook 26 in a position deployed (first position of the lever or levers 10, 10 ').

Selon une autre caractéristique de l'invention, ce doigt élastique 16 est défini de matière avec l'embout 9.According to another characteristic of the invention, this elastic finger 16 is defined in material with the tip 9.

A ce propos, on observera que cet embout 9 est, de préférence, réalisé en un matériau synthétique.In this regard, it will be observed that this nozzle 9 is preferably made of a synthetic material.

Selon un second type de réalisation de l'invention illustré figures 13 à 16, de tels moyens de rappel 15 sont définis au niveau du crochet 26, 26' comportant le levier 10, 10', ceci par une portion 32 de ce crochet 26 conçue apte à subir une déformation élastique et réversible sous l'effet d'une contrainte exercée sur le levier 10, 10' de ce crochet 26, 26'.According to a second embodiment of the illustrated invention Figures 13 to 16 , such return means 15 are defined at the hook 26, 26 'comprising the lever 10, 10', this by a portion 32 of the hook 26 designed adapted to undergo elastic deformation and reversible under the effect of a stress exerted on the lever 10, 10 'of this hook 26, 26'.

A ce propos, on observera que cette contrainte a pour effet d'amener un tel levier 10 d'une première position (dite position de repos dans laquelle ce levier 10 s'étend latéralement par rapport à l'embout 9) dans une seconde position dans laquelle ce levier 10 est au moins en partie escamoté. Dans cette seconde position, la portion 32 est sous contrainte et présente une déformation. Lorsque la contrainte n'est plus exercée sur le levier 10, la portion 32 se redresse jusqu'à ne plus être déformée et le levier 10 revient dans sa première position (position de repos).In this regard, it will be observed that this constraint has the effect of causing such a lever 10 of a first position (said rest position in which this lever 10 extends laterally relative to the end piece 9) in a second position. wherein this lever 10 is at least partially retracted. In this second position, the portion 32 is under stress and has a deformation. When the constraint is no longer exerted on the lever 10, the portion 32 recovers until no longer deformed and the lever 10 returns to its first position (rest position).

En fait, tel que visible sur les figures 13 à 16, de tels moyens de rappel 15 sont définis au niveau de la seconde partie 28 de ce crochet 26 par des moyens 33 apte à subir une déformation élastique réversible sous l'effet d'une contrainte exercée sur le levier 10 de ce crochet 26.In fact, as visible on the Figures 13 to 16 , such return means 15 are defined at the second portion 28 of this hook 26 by means 33 adapted to undergo a reversible elastic deformation under the effect of a stress exerted on the lever 10 of the hook 26.

A ce propos, on observera que cette seconde partie 28 du crochet 26 comporte deux axes 34, 34' constituant les moyens 33 aptes à subir une déformation élastique réversible et conçus pour adopter, l'un 34 par rapport à l'autre 34', d'une part, une première position dite de repos (figures 13, 14 et 16) dans laquelle le levier 10, associé à cette seconde partie 28, s'étend latéralement par rapport à l'embout 9 et, d'autre part, une seconde position dite sous contrainte (figure 15) dans laquelle ce levier 10 est au moins en partie escamoté sous l'effet d'une contrainte exercée sur ce levier 10.In this regard, it will be observed that this second portion 28 of the hook 26 has two pins 34, 34 'constituting the means 33 adapted to undergo a reversible elastic deformation and designed to adopt, one 34 relative to the other 34', on the one hand, a first so-called rest position ( Figures 13, 14 and 16 ) in which the lever 10, associated with this second part 28, extends laterally with respect to the end piece 9 and, secondly, a second position called under stress ( figure 15 ) in which this lever 10 is at least partly retracted under the effect of a constraint exerted on the lever 10.

Dans cette seconde position, les moyens 33 sont sous contrainte et présentent une déformation. Lorsque la contrainte n'est plus exercée sur le levier 10, les moyens 33 se redressent jusqu'à ne plus être déformés.In this second position, the means 33 are under stress and have a deformation. When the stress is no longer exerted on the lever 10, the means 33 are straightened until they are no longer deformed.

En fait, en position de repos, le crochet 26 peut être conçu en sorte que les deux axes 34, 34' forment un angle entre eux.In fact, in the rest position, the hook 26 can be designed so that the two axes 34, 34 'form an angle between them.

Cependant et selon un mode préféré de réalisation de l'invention illustré figures 13 à 16, les deux axes 34, 34' de la seconde partie 28 du crochet 26 s'étendant de manière sensiblement parallèle en position de repos du crochet 26 et du levier 10.However, and according to a preferred embodiment of the illustrated invention Figures 13 to 16 , the two axes 34, 34 'of the second portion 28 of the hook 26 extending substantially parallel in the rest position of the hook 26 and the lever 10.

Selon une autre caractéristique de l'invention, le crochet 26, correspondant aux second et troisième modes de réalisation illustrés figures 9 à 16, peut adopter la forme d'une pièce unique réalisée par pliage d'un élément tubulaire.According to another characteristic of the invention, the hook 26, corresponding to the second and third illustrated embodiments Figures 9 to 16 can take the form of a single piece made by folding a tubular element.

Dans un pareil cas, les axes 34, 34' des moyens 33 peuvent être constitués par un prolongement d'une portion en « U » constituant le levier 10 d'un tel crochet 26.In such a case, the axes 34, 34 'of the means 33 may be constituted by an extension of a "U" portion constituting the lever 10 of such a hook 26.

Une caractéristique additionnelle consiste en ce qu'au moins le crochet 26 correspondant au troisième mode de réalisation est, au moins en partie, réalisé en un matériau conçu pour subir une déformation élastique réversible, notamment en un matériau à mémoire de forme. Un tel matériau peut être de type métallique ou analogue.An additional feature is that at least the hook 26 corresponding to the third embodiment is, at least in part, made of a material designed to undergo reversible elastic deformation, in particular a shape memory material. Such a material may be of metal type or the like.

En ce qui concerne ledit embout 9 du dispositif de maintien 8, celui-ci est conçu apte à être engagé, en partie, à l'intérieur d'un logement défini au niveau de l'extrémité 6 latérale d'une lame 4 du tablier 3, cet embout 9 comportant des moyens 17 pour son immobilisation à l'intérieur de cette lame 4.With regard to said tip 9 of the holding device 8, it is designed to be engaged, in part, inside a housing defined at the level of the lateral end 6 of a blade 4 of the apron 3, this endpiece 9 having means 17 for its immobilization inside this blade 4.

Selon un mode de réalisation préféré de l'invention, les moyens d'immobilisation 17 que comporte l'embout 9 sont constitués par des moyens 18 destinés à recevoir des moyens d'immobilisation complémentaires associés à la lame 9 ou que comporte cette dernière 9.According to a preferred embodiment of the invention, the immobilization means 17 that comprises the tip 9 are constituted by means 18 for receiving additional immobilization means associated with the blade 9 or that comprises the latter 9.

En ce qui concerne lesdits moyens de réception 18, ceux-ci sont constitués par un logement défini au niveau de l'embout 9.As regards said receiving means 18, these consist of a housing defined at the endpiece 9.

En ce qui concerne les moyens d'immobilisation complémentaires, ceux-ci peuvent être constitués par une vis, un rivet ou analogue traversant une paroi de la lame 4 pour coopérer avec ledit logement des moyens de réception 18.As regards the complementary immobilization means, these may be constituted by a screw, a rivet or the like passing through a wall of the blade 4 to cooperate with said housing of the receiving means 18.

Cependant et selon un mode de réalisation préféré, les moyens d'immobilisation complémentaires sont constitués par des moyens de sertissage définis au niveau de cette lame 4, plus particulièrement au niveau d'au moins une découpe, réalisée au niveau d'une paroi de cette lame 4, et dont les bords sont conçus aptes à être repliés à l'intérieur de la lame 4 et à l'intérieur du logement des moyens de réception 18.However, and according to a preferred embodiment, the complementary immobilization means consist of crimping means defined at the level of this blade 4, more particularly at the level of at least one cut, made at a wall of this blade 4, and whose edges are designed to be folded inside the blade 4 and inside the housing of the receiving means 18.

Selon une autre caractéristique, l'embout 9 comporte, d'une part, une embase 19 destinée à être engagée à l'intérieur d'un logement défini au niveau de l'extrémité latérale 6 d'une lame 4 de tablier 3 et, d'autre part, un support 20 situé dans le prolongement de ladite embase 19 et destiné à venir se positionner extérieurement à ladite lame 4 et à l'intérieur d'une coulisse 7.According to another characteristic, the nozzle 9 comprises, on the one hand, a base 19 intended to be engaged inside a housing defined at the lateral end 6 of a deck blade 4 and, on the other hand, a support 20 located in the extension of said base 19 and intended to be positioned externally to said blade 4 and inside a slide 7.

C'est, plus particulièrement, au niveau de cette embase 19 que sont définis les moyens de réception 18 des moyens d'immobilisation complémentaires ainsi que, éventuellement, des moyens pour le guidage 21 de l'embout 9 à l'intérieur de la lame 4 lors de sa mise en place.It is, more particularly, at this base 19 that the means of reception 18 of the means are defined. additional immobilization as well as, possibly, means for guiding 21 of the nozzle 9 inside the blade 4 during its introduction.

De plus et comme visible figures 9 à 15 correspondant aux second et troisième modes de réalisation du dispositif de maintien 8 selon l'invention, c'est au niveau de cette embase 19 que peuvent être définis les moyens 29 de réception d'un crochet 26, plus particulièrement constitués par un logement ou analogue.In addition and as visible Figures 9 to 15 corresponding to the second and third embodiments of the holding device 8 according to the invention, it is at this base 19 that can be defined the means 29 for receiving a hook 26, more particularly constituted by a housing or the like .

Tel que visible sur les figures en annexe, c'est, plus particulièrement, au niveau dudit support 20 que comporte l'embout 9 que sont définis, d'une part, le ou les logements 14, 14' à l'intérieur desquels s'escamotent le ou les leviers 10, 10' et, d'autre part, les moyens de rappel 15 du ou des leviers 10, 10' des premier et second modes de réalisation de l'invention (figures 1 à 12).As can be seen in the appended figures, it is, more particularly, at the level of said support 20 that the end piece 9 is defined, on the one hand, the housing or recesses 14, 14 'inside which 'retract the lever or levers 10, 10' and, secondly, the return means 15 of the lever or levers 10, 10 'of the first and second embodiments of the invention ( Figures 1 to 12 ).

C'est, encore, au niveau de ce support 20 que sont positionnés le ou les leviers 10, 10' que comporte le dispositif de maintien 8.It is, again, at this support 20 that the lever or levers 10, 10 'that the holding device 8 has are positioned.

A ce propos, on observera que, conformément au premier mode de réalisation du dispositif de maintien 8 selon l'invention illustré figures 1 à 8, c'est, notamment, ce support 20 qui reçoit le ou les leviers 10, 10' de ce dispositif 8, plus particulièrement la pièce unique 13 au niveau de laquelle sont définis ce ou ces leviers 10, 10'.In this connection, it will be observed that, in accordance with the first embodiment of the holding device 8 according to the illustrated invention, Figures 1 to 8 it is, in particular, this support 20 which receives the lever or levers 10, 10 'of this device 8, more particularly the single piece 13 at which are defined or these levers 10, 10'.

Finalement, il convient d'observer que si la description qui précède concerne, essentiellement, un dispositif de maintien 8 comportant deux leviers 10, 10', la présente invention n'y est aucunement limitée et concerne, également, un tel dispositif 8 comportant un unique levier (premier type de réalisation susmentionné) adoptant, selon le cas, la forme d'une pièce unique conforme au premier mode de réalisation de l'invention mais comportant un unique levier ou la forme d'un unique crochet, conforme aux second et troisième modes de réalisation de l'invention, et comportant une première partie au niveau de laquelle est défini un tel levier ainsi qu'une seconde partie montée en basculement sur un embout.Finally, it should be observed that if the foregoing description concerns, essentially, a holding device 8 comprising two levers 10, 10 ', the present invention is in no way limited thereto and also relates to such a device 8 comprising a single lever (first embodiment mentioned above) adopting, as the case may be, the shape of a single piece according to the first embodiment of the invention but having a single lever or the form of a single hook, according to the second and third embodiments of the invention, and having a first portion at which is defined such a lever and a second portion mounted in tilting on a tip.

L'invention concerne, encore, une lame 4 de tablier 3 de volet roulant 1 présentant des extrémités latérales 6 destinées à se déplacer dans des coulisses latérales 7 que comporte un tel volet roulant 1. Une telle lame 4 reçoit, au niveau de l'une au moins de ses extrémités latérales 6, un dispositif de maintien 8 aux caractéristiques susmentionnées.The invention also relates to a blade 4 of rolling shutter apron 1 having lateral ends 6 intended to move in lateral slides 7 that includes such a shutter 1. Such a blade 4 receives, at the level of the at least one of its lateral ends 6, a holding device 8 with the above-mentioned characteristics.

Un mode préféré de réalisation consiste en une lame 4 de tablier 3 de volet roulant 1 recevant au niveau de ses deux extrémités latérales 6 un dispositif 8 de maintien selon l'invention.A preferred embodiment consists of a blade 4 of roller shutter apron 3 receiving at its two lateral ends 6 a holding device 8 according to the invention.

L'invention concerne, également, un volet roulant 1 comportant, d'une part, un tablier 3 constitué par un assemblage de lames 4, notamment articulées entre elles par le biais de moyens d'articulation 5, et présentant, chacune 4, des extrémités latérales 6 et, d'autre part, des coulisses latérales 7 à l'intérieur desquelles se déplacent les extrémités latérales 6 des lames 4 du tablier 3 de ce volet roulant 1. Ce volet roulant 1 comporte, alors, au niveau d'au moins une extrémité latérale 7 d'au moins une lame 4 du tablier 3, un dispositif de maintien 8 aux caractéristiques susmentionnées.The invention also relates to a shutter 1 comprising, on the one hand, an apron 3 consisting of an assembly of blades 4, in particular articulated together by means of articulation means 5, and each having 4 lateral ends 6 and, on the other hand, lateral slides 7 inside which move the lateral ends 6 of the blades 4 of the deck 3 of this shutter 1. This roller shutter 1 then comprises at the level of at at least one lateral end 7 of at least one blade 4 of the apron 3, a holding device 8 having the above-mentioned characteristics.

Un mode préféré de réalisation consiste en ce qu'une lame 4 sur deux, voire une lame 4 sur trois reçoit un tel dispositif de maintien 8.A preferred embodiment consists in that a blade 4 on two, or even a blade 4 on three receives such a holding device 8.

Selon une autre caractéristique du volet roulant 1 de l'invention, celui-ci comporte des moyens 22 conçus aptes à provoquer un escamotage du ou des leviers 10 ; 10' que comporte l'embout 9, ceci lors la pénétration de cet embout 9 dans la coulisse 7 et/ou lors de la sortie de cet embout 9 hors de cette coulisse 7.According to another characteristic of the shutter 1 of the invention, it comprises means 22 designed to cause a retraction of the lever or levers 10; 10 'that includes the tip 9, this during the penetration of this tip 9 in the slide 7 and / or at the exit of this nozzle 9 out of this slide 7.

Tel que visible sur la figure 6, de tels moyens d'escamotage 22 peuvent, d'une part, être disposés en sortie de la coulisse 7 et à l'intérieur du caisson 2 et, d'autre part, être constitués par une langue, un doigt 25, une lame, un déflecteur ou analogue conçu apte à appuyer sur un tel levier 10 pour le faire basculer en position d'escamotage, ceci lors de la pénétration de l'embout 9 dans la coulisse 7.As visible on the figure 6 such retraction means 22 may, on the one hand, be arranged at the outlet of the slide 7 and inside the casing 2 and, on the other hand, be constituted by a tongue, a finger 25, a blade , a baffle or the like designed adapted to press on such a lever 10 to tilt it into the retracted position, this during the penetration of the nozzle 9 in the slide 7.

De tels moyens d'escamotage 22 peuvent, encore, être constitués par une rampe de guidage 23, définie au niveau d'une tulipe de guidage 24 engagée dans la coulisse 7, et conçu apte à appuyer sur un tel levier 10 pour le faire basculer en position d'escamotage, ceci lors de la sortie de l'embout 9 hors de la coulisse 7.Such retraction means 22 may, again, be constituted by a guide ramp 23, defined at a guide tulip 24 engaged in the slide 7, and designed to press on such a lever 10 to tilt it. in the retracted position, this at the exit of the nozzle 9 out of the slide 7.

A ce propos, on observera que ces moyens 22 pour provoquer un escamotage du ou des leviers 10, 10' peuvent équiper un volet roulant 1 dont au moins une partie des lames 4 reçoit un dispositif de maintien 8 conforme à l'un quelconque des modes de réalisation susmentionnés (pièce unique 13 ou crochet 26).In this regard, it will be observed that these means 22 for causing a retraction of the lever or levers 10, 10 'can equip a shutter 1, at least a portion of the blades 4 receives a holding device 8 according to any of the modes aforementioned embodiments (single piece 13 or hook 26).

On remarquera, cependant, que, dans le cas des second et troisième modes de réalisation relatif à un levier 10 défini au niveau d'un crochet 26, ce crochet 26 est susceptible de basculer de part et d'autre de sa position déployée ce qui autorise, avantageusement, un basculement de ce crochet 26, d'une part et dans une certaine direction lors de l'entrée dans une coulisse 7 de la lame 4 équipée du dispositif de maintien 8 pourvue d'un tel crochet 26 (déploiement du tablier 3) et, d'autre part et dans une direction opposée lors de la sortie d'une telle lame 4 hors d'une telle coulisse 7 (repliement du tablier 3).It will be noted, however, that, in the case of the second and third embodiments relating to a lever 10 defined at a hook 26, this hook 26 is capable of tilting on either side of its deployed position which advantageously allows a tilting of this hook 26, on the one hand and in a certain direction when entering a slide 7 of the blade 4 equipped with the holding device 8 provided with such a hook 26 (deployment of the apron 3) and, on the other hand and in an opposite direction when exiting such a blade 4 out of such a slide 7 (folding apron 3).

Ce mode de réalisation autorise un entraînement en basculement d'un tel levier 10 ainsi que son escamotage, quel que soit le sens de défilement du tablier 3. Ceci permet, également, d'éviter tout accrochage d'un tel levier 10 avec une extrémité de la coulisse 7 ou avec la tulipe 24 et permet, avantageusement, d'éviter l'utilisation des moyens 22 pour provoquer un escamotage d'un tel levier 10.This embodiment allows a tilting drive of such a lever 10 and its retraction, regardless of the direction of travel of the apron 3. This also makes it possible to avoid any attachment of such a lever 10 with one end. of the slide 7 or with the tulip 24 and advantageously avoids the use of the means 22 to cause a retraction of such a lever 10.
