Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

Le secteur technique de la présente invention est celui des systèmes de fixation des dalles ou parements tels que ceux utilisés pour les plafonds ou pour former des cloisons verticales, horizontales ou inclinées. Plus particulièrement, l'invention concerne un système de verrouillage d'une dalle ou parement sur une structure de réception.The technical sector of the present invention is that of systems for fixing slabs or facings such as those used for ceilings or to form vertical, horizontal or inclined partitions. More particularly, the invention relates to a system for locking a slab or facing onto a receiving structure.

ETAT DE LA TECHNIQUESTATE OF THE ART

On connaît de FR2940988 des dalles pour plafond équipées de moyen de fixation qui sont déverrouillés au moyen d'un aimant produisant un champ magnétique.We know of FR2940988 ceiling tiles equipped with fixing means which are unlocked by means of a magnet producing a magnetic field.

De telles dalles présentent généralement une longueur et une largeur de plusieurs décimètre. Elles sont, suivant leurs dimensions, équipées de quatre, six ou huit moyens de fixation. Il apparaît toutefois un problème lorsqu'il est nécessaire de déverrouiller en même temps tous les moyens de fixation. En effet, si on déverrouille un par un les moyens de fixation, il y a une forte probabilité que le moyen de verrouillage qui n'est plus soumis à l'action du champ magnétique se verrouille à nouveau au cadre de réception de la dalle. Il est donc nécessaire de déverrouiller en même temps tous les moyens de fixation pour retirer la dalle du cadre de réception. Il est donc nécessaire de disposer d'autant d'aimants ou moyens magnétiques que de moyens de fixation ou bien d'un aimant ou moyen magnétique suffisamment gros et puissant pour déverrouiller en même temps tous les moyens de fixation. Cela rend difficilement réalisable l'opération de déverrouillage de la dalle par un seul opérateur d'autant plus qu'il est nécessaire de disposer d'outils encombrants.Such slabs generally have a length and width of several decimeters. They are, depending on their dimensions, equipped with four, six or eight fixing means. However, a problem arises when it is necessary to unlock all the fixing means at the same time. Indeed, if we unlock the fixing means one by one, there is a high probability that the locking means which is no longer subject to the action of the magnetic field will lock again to the receiving frame of the panel. It is therefore necessary to unlock all the fixing means at the same time to remove the panel from the receiving frame. It is therefore necessary to have as many magnets or magnetic means as there are fixing means or else a magnet or magnetic means large and powerful enough to unlock all the fixing means at the same time. This makes it difficult to unlock the slab by a single operator, especially since it is necessary to have bulky tools.

Un tel système nécessite cependant un outil de blocage permettant d'amener l'organe de rappel et donc le doigt de verrouillage en position non verrouillée. Il est donc nécessaire que la dalle présente un orifice d'accès permettant l'introduction de l'outil de blocage.The document FR2989395 describes a ratchet locking system further comprising a body, a locking finger, a first elastic member, a return member and a pawl for locking the finger in the unlocked position. Such However, the system requires a locking tool to bring the return member and therefore the locking finger into the unlocked position. It is therefore necessary for the slab to have an access hole allowing the insertion of the blocking tool.

Le but de la présente invention est de pallier les inconvénients précités en fournissant un système de verrouillage permettant un déverrouillage simple des dalles de leur cadre de fixation tout en préservant l'intégrité des dalles.The aim of the present invention is to overcome the aforementioned drawbacks by providing a locking system allowing simple unlocking of the tiles from their fixing frame while preserving the integrity of the tiles.

DESCRIPTION DETAILLEE DE MODES DE REALISATION DE L'INVENTIONDETAILED DESCRIPTION OF MODES OF CARRYING OUT THE INVENTION

Comme décrit précédemment, l'invention concerne un système de verrouillage d'une dalle sur une structure de réception. Le système comprend principalement un corps, un doigt de verrouillage, un organe élastique, un organe de rappel et un moyen de blocage.As described previously, the invention relates to a system for locking a slab onto a receiving structure. The system mainly comprises a body, a locking finger, an elastic member, a return member and a blocking means.

La figure 1 représente une vue éclatée d'un système de verrouillage 1 selon un mode de réalisation de l'invention. Le système de verrouillage 1 comprend un corps 2 de forme sensiblement parallélépipédique. Le corps 2 comprend en outre une face avant 21. La face avant 21 permet par exemple la fixation du corps 2 sur la dalle de façon à ce que le corps 2 soit solidaire de la dalle. Par exemple, la face avant 21 est fixée sur un élément de couverture de la dalle comme un rail 3 ou un repli de la matière de la dalle elle-même. Cet élément de couverture est situé en vis-à-vis du système de verrouillage 1 et est solidaire ou non de la dalle.There figure 1 represents an exploded view of a locking system 1 according to one embodiment of the invention. The locking system 1 comprises a body 2 of substantially parallelepiped shape. The body 2 further comprises a front face 21. The front face 21 allows for example the fixing of the body 2 on the slab so that the body 2 is integral with the slab. For example, the front face 21 is fixed to a covering element of the slab such as a rail 3 or a fold of the material of the slab itself. This covering element is located opposite the locking system 1 and is attached or not to the slab.

Le corps 2 reçoit un organe de rappel 4, un organe élastique 5, un doigt de verrouillage 6, un fourreau 7 et un moyen de blocage 8 de l'organe de rappel 4 en position repliée.The body 2 receives a return member 4, an elastic member 5, a locking finger 6, a sheath 7 and a blocking means 8 of the return member 4 in the folded position.

Le corps 2 comprend :

  • un logement 22 pour le doigt de verrouillage 6 disposé dans son fourreau 7, de forme adaptée pour une translation du doigt de verrouillage 6 par rapport au corps 2,
  • un logement 23 pour un axe 41 guidé en rotation de l'organe de rappel 4, et
  • deux logements 24 pour des bras 42 et 43 de l'organe de rappel 4.
Body 2 includes:
  • a housing 22 for the locking finger 6 arranged in its sheath 7, of shape adapted for a translation of the locking finger 6 relative to the body 2,
  • a housing 23 for an axis 41 guided in rotation of the return member 4, and
  • two housings 24 for arms 42 and 43 of the return member 4.

Ces logements 22, 23 et 24 du corps 2 peuvent communiquer entre eux et sont ouverts sur la face avant 21 du corps 2, la face avant 21 étant destinée à être fixée contre le bord d'une ouverture 31 réalisée dans le rail 3 ou le repli comme cela sera expliqué ci-après. Ainsi, le doigt de verrouillage 6 peut émerger par cette ouverture 31 hors du fourreau 7.These housings 22, 23 and 24 of the body 2 can communicate with each other and are open on the front face 21 of the body 2, the front face 21 being intended to be fixed against the edge of an opening 31 made in the rail 3 or the fallback as will be explained below. Thus, the locking finger 6 can emerge through this opening 31 out of the sheath 7.

Les logements 24 des bras 42 et 43 de l'organe de rappel 4 sont disposés de chaque côté du logement 23 recevant le doigt de verrouillage 6. Le logement 23 de l'axe 41 de l'organe de rappel 4 est disposé à l'avant du corps 2 et en dessous du logement 22 pour le doigt de verrouillage 6.The housings 24 of the arms 42 and 43 of the return member 4 are arranged on each side of the housing 23 receiving the locking finger 6. The housing 23 of the axis 41 of the return member 4 is arranged at the front of body 2 and below housing 22 for locking finger 6.

Le corps 2 comprend une paroi inférieure de laquelle deux dents 25 font légèrement saillie vers le haut, une paroi de fond et deux branches guides internes 26 disposées en vis-à-vis de la paroi inférieure. L'axe 41 de l'organe de rappel 4 est par exemple introduit en force dans son logement 23 dans le corps 2. Les branches internes 26 se déforment élastiquement lorsque l'axe 41 passe sur les dents 25 qui maintiennent ensuite l'axe 41 dans son logement 18 et donc l'organe de rappel 4 dans le corps 2. Ainsi, l'axe 41 de l'organe de rappel 4 vient en appui contre les dents 25 en permettant un mouvement de rotation de cet axe entre deux postions comme cela sera expliqué ci-après.The body 2 comprises a lower wall from which two teeth 25 project slightly upwards, a bottom wall and two internal guide branches 26 arranged opposite the lower wall. The axis 41 of the return member 4 is for example introduced by force into its housing 23 in the body 2. The internal branches 26 deform elastically when the axis 41 passes over the teeth 25 which then hold the axis 41 in its housing 18 and therefore the return member 4 in the body 2. Thus, the axis 41 of the return member 4 comes to bear against the teeth 25, allowing a rotational movement of this axis between two positions as this will be explained below.

Le doigt de verrouillage 6 délimite un logement borgne débouchant au niveau de son extrémité arrière destiné à la réception d'un organe élastique 5.The locking finger 6 delimits a blind housing opening at its rear end intended for receiving an elastic member 5.

L'organe de rappel 4 du doigt de verrouillage 6 permet en outre le passage de ce doigt de verrouillage 6 en position non verrouillée. L'organe de rappel 4 est ainsi apte à adopter une position repliée dans laquelle le doigt de verrouillage 6 est en position non verrouillée et une position dépliée dans laquelle le doigt de verrouillage 6 est en position verrouillée. L'organe de rappel 4 comprend en outre une partie magnétisable destinée à être mobilisée sous l'action d'un champ magnétique contre l'action de l'organe élastique 5. Ainsi, l'action d'un champ magnétique appliqué sous le système de verrouillage permet le passage de l'organe de rappel 4 de la position dépliée à la position repliée.The return member 4 of the locking finger 6 also allows this locking finger 6 to pass into the unlocked position. The return member 4 is thus able to adopt a folded position in which the locking finger 6 is in the unlocked position and an unfolded position in which the locking finger 6 is in the locked position. The return member 4 further comprises a magnetizable part intended to be mobilized under the action of a magnetic field against the action of the elastic member 5. Thus, the action of a magnetic field applied under the system locking allows the return member 4 to pass from the unfolded position to the folded position.

L'organe de rappel 4 comprend par exemple un axe 41 permettant la rotation de l'organe de rappel 4 autour de cet axe 41 et deux paires de bras 42 et 43. L'axe 41 est de forme sensiblement cylindrique. L'axe 41 est solidaire de deux paires de bras 42 et 43. Les bras 42 d'une même paire sont parallèles entre eux dans le même plan.The return member 4 comprises for example an axis 41 allowing the rotation of the return member 4 around this axis 41 and two pairs of arms 42 and 43. The axis 41 is of substantially cylindrical shape. The axis 41 is integral with two pairs of arms 42 and 43. The arms 42 of the same pair are parallel between them in the same plane.

L'organe de rappel 4 comprend également une partie magnétisable (non représenté sur la figure 1). La partie magnétisable peut par exemple être représentée par les branches 42 qui sont alors réalisées en un matériau magnétisable. La partie magnétisable peut également se présenter sous la forme d'une pièce supplémentaire pouvant se loger dans l'épaisseur ou sur la paroi des branches 42.The return member 4 also includes a magnetizable part (not shown on the figure 1 ). The magnetizable part can for example be represented by the branches 42 which are then made of a magnetizable material. The magnetizable part can also be in the form of an additional part which can be housed in the thickness or on the wall of the branches 42.

Le doigt de verrouillage 6 est mobile en translation dans le logement 22 réalisé dans le corps 2. Le doigt de verrouillage 6 est apte à adopter d'une part, une position verrouillée dans laquelle il vient en appui sur le cadre de réception et, d'autre part, une position non verrouillée dans laquelle il se retrouve entièrement dans le corps 2.The locking finger 6 is movable in translation in the housing 22 made in the body 2. The locking finger 6 is able to adopt, on the one hand, a locked position in which it comes to bear on the receiving frame and, On the other hand, an unlocked position in which it is entirely in body 2.

Le doigt de verrouillage 6 peut par exemple se présenter sous une forme sensiblement cylindrique. Il comprend en outre un biseau 61 réalisé sur sa partie avant et destiné à venir contre la structure de réception de la dalle. Le doigt de verrouillage 6 comprend également des ergots latéraux 62 de forme cylindrique destinée à coopérer avec l'organe de rappel 4 comme cela expliqué ci-après.The locking finger 6 can for example be in a substantially cylindrical shape. It further comprises a bevel 61 made on its front part and intended to come against the structure receiving the slab. The locking finger 6 also comprises lateral lugs 62 of cylindrical shape intended to cooperate with the return member 4 as explained below.

L'organe élastique 5 permet en outre le maintien du doigt de verrouillage 6 en position verrouillée comme cela est visible sur la figure 2. Il se présente par exemple sous la forme d'un ressort hélicoïdal. Ce ressort 5 peut être en métal. Le ressort 5 comprend par exemple deux extrémités. Une extrémité est insérée dans le logement du doigt de verrouillage 6 et l'autre extrémité libre est située en regard du fond du corps 2.The elastic member 5 also allows the locking finger 6 to be maintained in the locked position as is visible on the figure 2 . It takes the form of a helical spring, for example. This spring 5 can be made of metal. The spring 5 includes, for example, two ends. One end is inserted into the housing of the locking finger 6 and the other free end is located opposite the bottom of the body 2.

Le fourreau 7 est par exemple une douille de forme sensiblement cylindrique et comprend une collerette 71 avant et des griffes 72 arrières. Une rainure latérale 73 est réalisée de chaque côté du fourreau 7 afin de permettre le passage des ergots latéraux 62. La collerette 71 est destinée à venir en appui autour et à l'extérieur de l'ouverture 31 réalisée dans le rail 3 ou le repli en vis-à-vis du système de verrouillage 1.The sheath 7 is for example a socket of substantially cylindrical shape and comprises a front flange 71 and rear claws 72. A lateral groove 73 is made on each side of the sheath 7 in order to allow the passage of the lateral lugs 62. The collar 71 is intended to come to rest around and outside the opening 31 made in the rail 3 or the fold opposite the locking system 1.

Le fourreau 7 est guidé en translation dans le logement 22 du doigt de verrouillage 6 et est fixé par les griffes 72 en saillie à l'arrière du corps 2 du logement 22. Cette configuration permet de fixer l'ensemble constitué par le corps 2 et le fourreau 7 sur le rail 3 ou le repli. Le guidage en translation du doigt 6 dans son fourreau 7 peut être réalisé par les deux ergots 62 solidaires du doigt de verrouillage 6 et disposés de chaque côté du doigt de verrouillage 6 pour coulisser dans les rainures latérales 73 du fourreau 7. Le guidage en translation du doigt de verrouillage 6 par rapport au fourreau 7 peut être réalisé par le logement 22 de forme complémentaire à celle du doigt de verrouillage 6 et correspondant sensiblement à la section du doigt de verrouillage 6.The sheath 7 is guided in translation in the housing 22 of the locking finger 6 and is fixed by the claws 72 projecting from the rear of the body 2 of the housing 22. This configuration makes it possible to fix the assembly consisting of the body 2 and the sheath 7 on the rail 3 or the fold. The translation guidance of the finger 6 in its sheath 7 can be achieved by the two lugs 62 secured to the locking finger 6 and arranged on each side of the locking finger 6 to slide in the lateral grooves 73 of the sheath 7. The translation guidance of the locking finger 6 relative to the sheath 7 can be produced by the housing 22 of a shape complementary to that of the locking finger 6 and corresponding substantially to the section of the locking finger 6.

Le moyen de blocage 8 comprend en outre une première partie 81 destinée à se trouver en appui contre l'organe de rappel 4 en position repliée. La première partie 81 permet en outre de maintenir l'organe de rappel 4 en position repliée. La première partie 81 permet également de fixer le moyen de blocage 8 sur le corps 2.The blocking means 8 further comprises a first part 81 intended to bear against the return member 4 in the folded position. The first part 81 also makes it possible to maintain the return member 4 in the folded position. The first part 81 also makes it possible to fix the blocking means 8 on the body 2.

Le moyen de blocage 8 comprend également une deuxième partie 82 apte à permettre la déformation du moyen de blocage 8 par application d'une force sur ladite deuxième partie 82. Cela permet en outre à la première partie 81 de se retrouver à l'écart de l'organe de rappel 4 en position repliée de façon à permettre le passage de l'organe de rappel 4 de la position repliée à la dépliée. Ce retour en position dépliée est en outre permis par l'action de l'organe élastique 5 sur le doigt de verrouillage 6 et par la coopération entre le doigt de verrouillage 6 et l'organe de rappel 4 par l'intermédiaire des ergots 62.The blocking means 8 also comprises a second part 82 capable of allowing the deformation of the blocking means 8 by application of a force on said second part 82. This also allows the first part 81 to be located away from the return member 4 in the folded position so as to allow the return member 4 to pass from the folded position to the unfolded position. This return to the unfolded position is also made possible by the action of the elastic member 5 on the locking finger 6 and by the cooperation between the locking finger 6 and the return member 4 via the lugs 62.

Ainsi, la première partie 81 du moyen de blocage 8 se retrouve à l'intérieur du corps 2 de façon à coopérer avec l'organe de rappel 4. Sa deuxième partie 82 se trouve à l'extérieur du corps 2.Thus, the first part 81 of the blocking means 8 is found inside the body 2 so as to cooperate with the return member 4. Its second part 82 is located outside the body 2.

La deuxième partie 82 du moyen de blocage 8 est par exemple située sur la partie externe de la partie supérieure du corps 2. Elle s'étend de l'arrière du corps 2 jusqu'à l'avant du corps 2.The second part 82 of the blocking means 8 is for example located on the external part of the upper part of the body 2. It extends from the rear of the body 2 to the front of the body 2.

La première partie 81 du moyen de blocage 8 est par exemple située à l'intérieur du corps 2. Elle s'étend de l'avant du corps 2 vers l'intérieur du corps 2.The first part 81 of the blocking means 8 is for example located inside the body 2. It extends from the front of the body 2 towards the inside of the body 2.

Selon un mode de réalisation de l'invention, le moyen de blocage 8 comprend successivement une première extrémité 83, un premier coude 84, un renflement 85, un deuxième coude 86 et une deuxième extrémité 87.According to one embodiment of the invention, the locking means 8 successively comprises a first end 83, a first elbow 84, a bulge 85, a second elbow 86 and a second end 87.

Selon un autre mode de réalisation de l'invention, le moyen de blocage 8 se présente par exemple sous la forme d'une lame plate comprenant une première partie 81 et une deuxième partie 82. La lame plate peut par exemple être réalisée d'un seul tenant en un matériau métallique. La première partie 81 est alors représentée par la portion située entre le deuxième coude 86 et la deuxième extrémité 87. La deuxième partie 85 est alors représentée par la portion située entre la première extrémité 83 et le deuxième coude 86 et comprend le renflement 85.According to another embodiment of the invention, the blocking means 8 is for example in the form of a flat blade comprising a first part 81 and a second part 82. The flat blade can for example be made of a made of a metallic material. The first part 81 is then represented by the portion located between the second elbow 86 and the second end 87. The second part 85 is then represented by the portion located between the first end 83 and the second elbow 86 and includes the bulge 85.

La lame plate peut par exemple comprendre, de l'arrière du corps 2 vers la face avant 21 du corps 2, une première extrémité 83, un premier coude 84, un renflement 85, un deuxième coude 86 et une deuxième extrémité 87. La première partie 81 est alors représentée par la portion située entre le deuxième coude 86 et la deuxième extrémité 87. La deuxième partie 85 est alors représentée par la portion située entre la première extrémité 83 et le deuxième coude 86 et comprend le renflement 85.The flat blade can for example comprise, from the rear of the body 2 towards the front face 21 of the body 2, a first end 83, a first bend 84, a bulge 85, a second bend 86 and a second end 87. The first part 81 is then represented by the portion located between the second elbow 86 and the second end 87. The second part 85 is then represented by the portion located between the first end 83 and the second elbow 86 and includes the bulge 85.

La première extrémité 83 est par exemple située à l'arrière du corps 2 ou dans une fente pratiquée dans l'épaisseur de la face arrière du corps 2. Le premier coude 84 est situé au niveau de la jonction entre la face supérieure et la face arrière du corps 2. Le deuxième coude 86 est situé à l'avant du corps 2 au niveau de l'extrémité avant de la face supérieure du corps 2. Le renflement 85 est alors situé sur la partie externe de la face supérieure du corps 2 et la deuxième extrémité 81 est située dans le corps 2. L'application d'une force de haut en bas par exemple sur le renflement 85 permet ainsi de déformer le moyen de blocage 8 sans le désolidariser du corps 2. Le renflement 85 permet également deThe first end 83 is for example located at the rear of the body 2 or in a slot made in the thickness of the rear face of the body 2. The first elbow 84 is located at the junction between the upper face and the face rear of the body 2. The second elbow 86 is located at the front of the body 2 at the level of the front end of the upper face of the body 2. The bulge 85 is then located on the external part of the upper face of the body 2 and the second end 81 is located in the body 2. The application of a force from top to bottom for example on the bulge 85 thus makes it possible to deform the blocking means 8 without separating it from the body 2. The bulge 85 also allows of

En outre, l'application de haut en bas d'une force au niveau du renflement 85 de la deuxième partie 82 du moyen de blocage 8 permet de déformer le moyen de blocage 8 et de permettre à la deuxième extrémité 87 de se déplacer vers le haut par rapport à sa position initiale.In addition, applying a force from top to bottom at the level of the bulge 85 of the second part 82 of the means of blocking 8 makes it possible to deform the blocking means 8 and to allow the second end 87 to move upwards relative to its initial position.

Lors du montage, le doigt 6 est introduit avec l'organe élastique 5 dans le corps 2. L'organe élastique 5 est disposé entre la face arrière du doigt de verrouillage 6 et la paroi interne du corps 2. La partie biseautée 61 du doigt de verrouillage 61 est orientée vers le haut.During assembly, the finger 6 is introduced with the elastic member 5 into the body 2. The elastic member 5 is arranged between the rear face of the locking finger 6 and the internal wall of the body 2. The beveled part 61 of the finger locking 61 is oriented upwards.

Le moyen de blocage 8 et l'organe de rappel 4 sont ensuite insérés dans le corps 2. Les bras 42 et 43 de l'organe de rappel 4 viennent de part et d'autre de chacun des ergots 62 du doigt de verrouillage 6. Le corps 2 est ensuite disposé contre le bord d'une découpe 31 réalisée dans un rail 3 ou le repli venant en vis-à-vis du système de verrouillage 1.The blocking means 8 and the return member 4 are then inserted into the body 2. The arms 42 and 43 of the return member 4 come on either side of each of the lugs 62 of the locking finger 6. The body 2 is then placed against the edge of a cutout 31 made in a rail 3 or the fold facing the locking system 1.

Le fourreau 7 est ensuite introduit dans l'ouverture 31 du rail 3 ou repli pour pénétrer dans le logement 22 du doigt de verrouillage 6. La collerette 71 est disposée en appui contre le rail 3 ou repli et les griffes 72 sont bloquées à l'arrière dans le corps 2.The sheath 7 is then introduced into the opening 31 of the rail 3 or fold to penetrate into the housing 22 of the locking finger 6. The collar 71 is arranged to rest against the rail 3 or fold and the claws 72 are blocked at the rear in body 2.

Les références au haut, bas, dessus, dessous, avant et arrière du système de verrouillage 1 ou du corps 2 correspondent à une dalle horizontale insérée du bas vers le haut pour un plafond. Bien entendu, les dalles peuvent aussi être disposées verticalement ou inclinées voire même horizontalement pour former un plancher pour lequel les dalles sont alors insérées du haut vers le bas.The references to the top, bottom, top, bottom, front and rear of the locking system 1 or body 2 correspond to a horizontal slab inserted from bottom to top for a ceiling. Of course, the slabs can also be arranged vertically or inclined or even horizontally to form a floor for which the slabs are then inserted from top to bottom.

Des détails supplémentaires apparaissent sur les figures 2 à 5 illustrant quatre positions fonctionnelles du système de verrouillage 1 selon un mode de réalisation de l'invention. Les cloisons latérales du corps 2 du système de verrouillage 1 ont été retirées pour les besoins de la description. Ces figures illustrent la coopération entre le doigt de verrouillage 6, l'organe de rappel 4 et le moyen de blocage 8.Additional details appear on the figures 2 to 5 illustrating four functional positions of the locking system 1 according to one embodiment of the invention. The side partitions of the body 2 of the locking system 1 have been removed for the purposes of the description. These figures illustrate the cooperation between the locking finger 6, the return member 4 and the blocking means 8.

Sur la figure 2, le doigt de verrouillage 6 est disposé dans une position verrouillée qui correspond à la position dans laquelle se trouve le système de verrouillage 1 avant ou après l'insertion de la dalle dans la structure de réception. Le doigt de verrouillage 6 est en position saillante au maximum et sa portion biseautée 61 est disposée face au la structure de réception avant l'insertion de la dalle.On the figure 2 , the locking finger 6 is arranged in a locked position which corresponds to the position in which the locking system 1 is located before or after the insertion of the slab into the receiving structure. The locking finger 6 is in the maximum protruding position and its beveled portion 61 is placed facing the receiving structure before insertion of the slab.

La position verrouillée du doigt de verrouillage 6 correspond également à la position du doigt de verrouillage 6 après insertion de la dalle dans la structure de réception. Le doigt de verrouillage 6 retrouve sa position saillante au maximum pour venir en appui contre la structure de réception. La portion venant en appui contre la structure de réception dans la position verrouillée est la portion 63 opposé au biseau 61.The locked position of the locking finger 6 also corresponds to the position of the locking finger 6 after insertion of the slab into the receiving structure. The locking finger 6 returns to its maximum protruding position to come to rest against the receiving structure. The portion bearing against the receiving structure in the locked position is the portion 63 opposite the bevel 61.

L'organe élastique 5, en appui sur le corps 2, repousse le doigt de verrouillage 6 et maintient le doigt de verrouillage 6 en position verrouillée.The elastic member 5, resting on the body 2, pushes back the locking finger 6 and maintains the locking finger 6 in the locked position.

Dans cette position, l'organe de rappel 4 qui est en position dépliée, n'exerce pas d'action sur le doigt de verrouillage 6. Les ergots 62 du doigt de verrouillage 6 viennent simplement en contact avec les bras 43 de l'organe de rappel 4 et maintiennent ainsi l'organe de rappel 4 en position repliée.In this position, the return member 4 which is in the unfolded position does not exert any action on the locking finger 6. The lugs 62 of the locking finger 6 simply come into contact with the arms 43 of the member return member 4 and thus maintain the return member 4 in the folded position.

Le rail 3 ou repli (non représenté sur la figure 2), auquel est fixé le système de verrouillage 1, est disposé entre la face d'appui 21 du corps 2 et la collerette 71 du fourreau 7.Rail 3 or fold (not shown on the figure 2 ), to which the locking system 1 is fixed, is arranged between the bearing face 21 of the body 2 and the flange 71 of the sheath 7.

Les griffes 72 de fixation du fourreau 7 font saillie hors du corps 2 en venant s'accrocher sur la paroi arrière dudit corps.The claws 72 for fixing the sheath 7 project out of the body 2, hooking onto the rear wall of said body.

Les parties magnétisables sont disposées à proximité de l'extrémité libre de chacun des bras 42 positionnés en dessous des ergots 62.The magnetizable parts are arranged near the free end of each of the arms 42 positioned below the lugs 62.

Selon un mode de réalisation particulier de l'invention, la partie magnétisable des bras 42 s'étend chacune sur une portion de chaque bras 42 s'étendant depuis son extrémité libre jusqu'à environ la moitié de sa longueur. Selon un autre mode de réalisation de l'invention, la partie magnétisable est une pièce supplémentaire insérée dans chacun des bras 42 par son extrémité libre dans laquelle un évidement est pratiqué.According to a particular embodiment of the invention, the magnetizable part of the arms 42 each extends over a portion of each arm 42 extending from its free end to approximately half of its length. According to another embodiment of the invention, the magnetizable part is an additional part inserted into each of the arms 42 by its free end in which a recess is made.

La partie magnétisable est destinée à déplacer l'organe de rappel 4 sous l'action d'un champ magnétique. L'attraction de la partie magnétisable par un champ magnétique venant d'en dessous du système de verrouillage 1 entraîne ainsi la rotation de l'organe de rappel 4 autour de son axe 41, l'abaissement des bras 42 et le déplacement vers le fond du corps 2 des bras 43 comme cela est visible sur les figures 4 et 5. Ainsi, par l'action d'un champ magnétique venant d'en dessous du système de verrouillage 1, l'organe de rappel 4 passe de la position dépliée à la position repliée.The magnetizable part is intended to move the return member 4 under the action of a magnetic field. The attraction of the magnetizable part by a magnetic field coming from it below the locking system 1 thus causes the rotation of the return member 4 around its axis 41, the lowering of the arms 42 and the movement towards the bottom of the body 2 of the arms 43 as is visible on the figures 4 and 5 . Thus, by the action of a magnetic field coming from below the locking system 1, the return member 4 passes from the unfolded position to the folded position.

Le moyen de blocage 8 n'exerce pas d'action sur l'organe de rappel 4 en position dépliée. Le moyen de blocage 8 est de conception telle qu'il autorise le passage de l'organe de rappel 4 de la position dépliée à la position repliée.The blocking means 8 does not exert any action on the return member 4 in the unfolded position. The blocking means 8 is designed such that it allows the return member 4 to pass from the unfolded position to the folded position.

La figure 3 représente la position du doigt de verrouillage 6 au moment de l'insertion de la dalle dans la structure de réception. Le doigt de verrouillage 6 affleure la surface externe de la collerette 71 et ne fait pas saillie hors du fourreau 7. Un jeu peut être prévu entre cette collerette 35 et la structure de réception de la dalle auquel cas le doigt de verrouillage 6 vienne en retrait par rapport à sa position de verrouillage représentée à la figure 2. La représentation de la figure 3 correspond à un recul maximum nécessaire du doigt de verrouillage 6 lors de l'insertion de la dalle dans la structure de réception.There Figure 3 represents the position of the locking finger 6 at the time of insertion of the slab into the receiving structure. The locking finger 6 is flush with the external surface of the flange 71 and does not project out of the sheath 7. A clearance can be provided between this flange 35 and the structure receiving the slab in which case the locking finger 6 is recessed relative to its locking position shown in figure 2 . The representation of the Figure 3 corresponds to a maximum necessary recoil of the locking finger 6 when inserting the slab into the receiving structure.

L'organe de rappel 4 ne perturbe pas le mouvement de translation effectué par le doigt de verrouillage 6. En particulier, même si les ergots 62 du doigt de verrouillage 6 viennent en contact avec les bras 42 ou 43 de l'organe de rappel 4, l'organe de rappel 4 n'est ici pas déplacé par la translation du doigt de verrouillage 6. L'organe de rappel 4 ne bloque pas le doigt de verrouillage 6 dans ses positions intermédiaires et le moyen de blocage 8 n'exerce pas d'action sur l'organe de rappel 4. Ainsi, lors de l'insertion de la dalle dans la structure de réception, on réalise le verrouillage automatique de la dalle dans la structure de réception.The return member 4 does not disturb the translation movement carried out by the locking finger 6. In particular, even if the lugs 62 of the locking finger 6 come into contact with the arms 42 or 43 of the return member 4 , the return member 4 is not here moved by the translation of the locking finger 6. The return member 4 does not block the locking finger 6 in its intermediate positions and the blocking means 8 does not exert of action on the return member 4. Thus, when inserting the slab into the receiving structure, the slab is automatically locked in the receiving structure.

Sur la figure 4, on a représenté le doigt de verrouillage 6 en position non verrouillée. Le doigt de verrouillage 6 adopte ici sa position de recul maximum dans le logement 22 du corps 2. L'application d'un champ magnétique venant d'en dessous du système de verrouillage 1 entraîne la rotation de l'organe de rappel 4 autour de son axe 41, l'abaissement des bras 42 vers le fond du corps 2.On the figure 4 , the locking finger 6 is shown in the unlocked position. The locking finger 6 here adopts its maximum recoil position in the housing 22 of the body 2. The application of a magnetic field coming from it below the locking system 1 causes the rotation of the return member 4 around its axis 41, the lowering of the arms 42 towards the bottom of the body 2.

Le déplacement vers le fond du corps 2 des bras 43 entraîne le déplacement en translation du doigt de verrouillage 6. En effet, les bras 43 viennent buter contre les ergots 62 ce qui entraîne le doigt de verrouillage 6 dans sa position non verrouillée, et cela contre l'action de l'organe élastique 5.The movement towards the bottom of the body 2 of the arms 43 causes the translational movement of the locking finger 6. In fact, the arms 43 abut against the lugs 62 which causes the locking finger 6 in its unlocked position, and this against the action of the elastic member 5.

Ainsi, sous l'action d'un champ magnétique, l'organe de rappel 4 se retrouve en position repliée et le doigt de verrouillage 6 en position non verrouillée.Thus, under the action of a magnetic field, the return member 4 finds itself in the folded position and the locking finger 6 in the unlocked position.

Le moyen de blocage 8 vient alors en appui contre l'organe de rappel 4 de façon à maintenir l'organe de rappel 4 en position repliée, ce qui maintient le doigt de verrouillage 6 en position non verrouillée. Ainsi, l'organe de rappel 4 est maintenu en position repliée même en l'absence d'un champ magnétique exercé par le dessous du système de verrouillage 1.The blocking means 8 then comes to bear against the return member 4 so as to maintain the return member 4 in the folded position, which maintains the locking finger 6 in the unlocked position. Thus, the return member 4 is maintained in the folded position even in the absence of a magnetic field exerted from below the locking system 1.

Les bras 43 de l'organe de rappel 4 sont en appui contre les ergots 62 du doigt de verrouillage 6 qui est maintenu dans la position non verrouillée et il ne peut ainsi plus se verrouiller contre la structure de réception de la dalle. L'organe de rappel 4 maintient le doigt en position non verrouillée malgré l'action du premier organe élastique 5 comprimé entre le doigt de verrouillage 6 et le corps 2.The arms 43 of the return member 4 bear against the lugs 62 of the locking finger 6 which is held in the unlocked position and it can thus no longer be locked against the structure receiving the slab. The return member 4 maintains the finger in the unlocked position despite the action of the first elastic member 5 compressed between the locking finger 6 and the body 2.

Selon le mode de réalisation de l'invention représenté sur la figure 4, c'est la deuxième extrémité 87 du moyen de blocage 8 qui vient en appui contre l'organe de rappel 8 en position repliée et maintient ainsi l'organe de rappel 8 en position repliée.According to the embodiment of the invention represented on the Figure 4 , it is the second end 87 of the blocking means 8 which comes to bear against the return member 8 in the folded position and thus maintains the return member 8 in the folded position.

Le moyen de blocage 8 est de conception telle qu'il permet de maintenir l'organe de rappel 4 en position repliée. En outre, le moyen de blocage 8 permet de maintenir l'organe de rappel 4 en position repliée et, ce, malgré la force contraire exercée par l'organe élastique 5.The blocking means 8 is designed such that it allows the return member 4 to be maintained in the folded position. Furthermore, the blocking means 8 makes it possible to maintain the return member 4 in the folded position, despite the opposing force exerted by the elastic member 5.

Ainsi, pour une dalle comprenant plusieurs systèmes de verrouillage 1 selon l'invention, en positionnant l'ensemble des systèmes de verrouillage 1 en position non verrouillée, donc chaque organe de rappel 4 en position repliée et maintenu ainsi par les moyens de blocage 8, la dalle peut être retirée de la structure de réception et inversement.Thus, for a slab comprising several locking systems 1 according to the invention, by positioning all of the locking systems 1 in the unlocked position, therefore each return member 4 in the folded and maintained position thus by the blocking means 8, the slab can be removed from the receiving structure and vice versa.

Une fois la dalle retirée de son cadre de réception, la deuxième partie 82 de chaque moyen de blocage 8 de chaque système de verrouillage 1 est accessible pour un utilisateur.Once the slab has been removed from its receiving frame, the second part 82 of each blocking means 8 of each locking system 1 is accessible to a user.

La figure 5 illustre l'instant de la libération de l'organe de rappel 4 après la récupération de la dalle. Pour replacer ladite dalle dans le plafond, il faut amener le doigt 6 dans la position représentée sur la figure 2. En exerçant une force (F) par exemple sur la deuxième partie 82 du moyen de blocage 8 qui est devenu accessible, le moyen de blocage 8 se déforme et la première partie 81 se retrouve écartée de l'organe de rappel 4 en position dépliée. Le doigt de verrouillage 6 revient alors, sous l'action de l'organe élastique 5, dans sa position verrouillée telle que représentée à la figure 2.There Figure 5 illustrates the moment of release of the return member 4 after recovery of the slab. To replace said tile in the ceiling, you must bring finger 6 to the position shown on the figure 2 . By exerting a force (F) for example on the second part 82 of the blocking means 8 which has become accessible, the blocking means 8 is deformed and the first part 81 finds itself separated from the return member 4 in the unfolded position. The locking finger 6 then returns, under the action of the elastic member 5, to its locked position as shown in figure 2 .

Le retour en position verrouillée du doigt de verrouillage 6 ne nécessite aucun outil particulier. Une simple pression du doigt par exemple sur le renflement 85 suffit à déformer le moyen de blocage 8 et à entraîner un déplacement vers le haut de la deuxième extrémité 87 du moyen de blocage 8.Returning the locking finger 6 to the locked position does not require any special tools. A simple pressure of the finger for example on the bulge 85 is enough to deform the blocking means 8 and to cause an upward movement of the second end 87 of the blocking means 8.

Ainsi, le moyen de blocage 8 selon l'invention remplit plusieurs fonctions différentes et cela dans différentes positions de l'organe de rappel 4.Thus, the blocking means 8 according to the invention fulfills several different functions and this in different positions of the return member 4.

En effet, le moyen de blocage 8 autorise le passage de l'organe de rappel 4 de la position repliée de la figure 5 à la position dépliée de la figure 2. La première partie 81 du moyen de blocage 8 ne bloque pas le déplacement des bras 43 depuis l'avant du corps 2 vers l'arrière du corps 2. Les bras 43 de l'organe de rappel 4 sont en contact intime avec la partie inférieure de la première partie 81 du moyen de blocage 8 qui se déforme légèrement pour permettre le déplacement des bras 43 depuis le deuxième coude 86 vers la deuxième extrémité 87 du moyen de blocage 8. Par exemple, lors du passage de l'organe de rappel 4 en position dépliée, l'extrémité libre du bras 43 parcourt la première partie 81 du moyen de blocage 8 depuis le deuxième coude 86 jusqu'à dépasser la deuxième extrémité 87 du moyen de blocage 8.In fact, the blocking means 8 allows the return member 4 to pass from the folded position of the Figure 5 to the unfolded position of the figure 2 . The first part 81 of the blocking means 8 does not block the movement of the arms 43 from the front of the body 2 towards the rear of the body 2. The arms 43 of the return member 4 are in intimate contact with the lower part of the first part 81 of the blocking means 8 which deforms slightly to allow the movement of the arms 43 from the second elbow 86 towards the second end 87 of the blocking means 8. For example, during the passage of the return member 4 in the unfolded position, the free end of the arm 43 runs along the first part 81 of the blocking means 8 from the second elbow 86 until it passes the second end 87 of the blocking means 8.

Selon le mode de réalisation de l'invention représenté sur la figure 5, le moyen de blocage comprend également un troisième coude 88 situé entre la première extrémité 83 et le premier coude 84. Le troisième coude 88 est de conception telle qu'il permet la préhension de la première extrémité 83.According to the embodiment of the invention represented on there Figure 5 , the blocking means also comprises a third elbow 88 located between the first end 83 and the first elbow 84. The third elbow 88 is of such a design that it allows the first end 83 to be gripped.

Comme représenté sur la figure 6, cela permet en outre d'appliquer une force F2 du bas vers le haut au niveau de la première extrémité 83 de la deuxième partie 82 du moyen de blocage 8. L'application de cette force permet de déformer et de faire pivoter le moyen de blocage 8 ce qui permet à la deuxième extrémité 87 de se déplacer vers le haut par rapport à sa position initiale. Ainsi, lors de l'application de la force F2 sur la première extrémité 83 du moyen de blocage 8, la deuxième extrémité 87 se retrouve à l'écart de l'organe de rappel 4 en position repliée.As shown on the Figure 6 , this further makes it possible to apply a force F2 from bottom to top at the level of the first end 83 of the second part 82 of the blocking means 8. The application of this force makes it possible to deform and rotate the means of blocking 8 which allows the second end 87 to move upwards relative to its initial position. Thus, when the force F2 is applied to the first end 83 of the blocking means 8, the second end 87 finds itself away from the return member 4 in the folded position.

Ce mode de réalisation permet d'aboutir aux mêmes résultats que lorsqu'une force F1 est appliquée sur le renflement 85 du moyen de blocage 8.This embodiment makes it possible to achieve the same results as when a force F1 is applied to the bulge 85 of the blocking means 8.

Le moyen de blocage 8 permet également de maintenir l'organe de rappel 4 en position repliée. En effet, lorsque les bras 43 se déplacent vers l'arrière du corps 2, ils déforment légèrement la première partie 81 de moyen de blocage 8 jusqu'à dépasser la deuxième extrémité 87 du moyen de blocage 8. La première partie 81 du moyen de blocage 8 reprend alors sa position initiale et vient en appui au niveau de l'extrémité libre de bras 43 de l'organe de rappel 4 comme cela est illustré sur la figure 4. Dans cette configuration le moyen de blocage 8 maintient l'organe de rappel 4 en position repliée en interdisant le retour, sous l'effet de l'organe élastique 5, de l'organe de rappel 4 en position repliée. En effet, l'organe de blocage 8 exerce ici une force inverse à la force exercée par l'organe élastique 5, par l'intermédiaire des ergots 62 du doigt de verrouillage 6, sur l'organe de rappel 4 qui est ainsi maintenu en position repliée.The blocking means 8 also makes it possible to maintain the return member 4 in the folded position. Indeed, when the arms 43 move towards the rear of the body 2, they slightly deform the first part 81 of the blocking means 8 until they exceed the second end 87 of the blocking means 8. The first part 81 of the blocking means blocking 8 then returns to its initial position and comes to bear at the level of the free end of arm 43 of the return member 4 as is illustrated in the Figure 4 . In this configuration, the blocking means 8 maintains the return member 4 in the folded position by preventing the return, under the effect of the elastic member 5, of the return member 4 in the folded position. In fact, the blocking member 8 here exerts a force opposite to the force exerted by the elastic member 5, via the lugs 62 of the locking finger 6, on the return member 4 which is thus held in place. folded position.

Le moyen de blocage 8 autorise également le passage de l'organe de rappel 4 de la position repliée à la position dépliée en se déformant sous l'action d'une force exercée (F1 ou F2) sur la deuxième partie 82 du moyen de blocage 8 accessible lorsque la dalle a été retirée de la structure de fixation. La conception particulière du moyen de blocage 8 ainsi que sa coopération avec le corps 2 permettent à la deuxième extrémité 87 du moyen de blocage 8 de se déplacer vers la face supérieure du corps lorsqu'une force (F1) de haut en bas est exercée sur le renflement 85 ou lorsqu'une une force (F2) de bas en haut est exercée sur la première extrémité 835.The blocking means 8 also allows the return member 4 to pass from the folded position to the unfolded position by deforming under the action of a force exerted (F1 or F2) on the second part 82 of the blocking means 8 accessible when the slab has been removed from the structure fixation. The particular design of the blocking means 8 as well as its cooperation with the body 2 allow the second end 87 of the blocking means 8 to move towards the upper face of the body when a force (F1) from top to bottom is exerted on the bulge 85 or when a force (F2) from bottom to top is exerted on the first end 835.

Le système de verrouillage 1 selon l'invention est par exemple destiné à être installé sur des dalles pour permettre leur verrouillage sur une structure de fixation adaptée. Une dalle comprend par exemple deux systèmes de verrouillage 1 selon l'invention. Selon la dimension de la dalle, le nombre de système de verrouillage est adapté en fonction.The locking system 1 according to the invention is for example intended to be installed on slabs to allow them to be locked on a suitable fixing structure. A slab comprises for example two locking systems 1 according to the invention. Depending on the size of the slab, the number of locking systems is adapted accordingly.

De façon à permettre le passage du doigt de verrouillage 6 de la position verrouillée à la position verrouillée, il est possible de fournir un kit comprenant une dalle équipée d'au moins deux systèmes de verrouillage 1 selon l'invention et un moyen d'émission d'un champ magnétique, par exemple un aimant.In order to allow the locking finger 6 to move from the locked position to the locked position, it is possible to provide a kit comprising a panel equipped with at least two locking systems 1 according to the invention and an emission means of a magnetic field, for example a magnet.
