Abstract

The invention concerns an apparatus comprising first and second planar elements, e.g. of cardboard, which may be assembled together to form a structure, e.g. a cross brace of a bottle crate. Each of these elements has a slit which extends to an edge of the respective element and into which the other element may be introduced. The slits of the two elements have linear portions which are aligned in a predetermined direction when the elements are assembled. The slit of the first element is formed to provide a flap which extends transversely with respect to the predetermined direction and which is pivotable about a folding line which extends obliquely with respect to the predetermined direction. The second element has an aperture in which the flap is engaged with the elements are assembled. Assembly of the elements in a mutually orthogonal position permits the flap to be freely pivoted about the folding line without engaging an edge of the aperture, while subsequent movement of the elements from the orthogonal position to a further position in which they lie against one another prevents the flap from pivoting freely about the folding line without engaging an edge of the aperture.

Description

La présente invention concerne un système d'assemblage d'éléments en plaques en une matière semi-rigide telle que le carton ondulé. Elle concerne plus particulièrement un système de ce type qui puisse être appliqué à des éléments plans imbriqués, susceptibles, par pivotement, d'être ame­nés à plat les uns contre les autres, ledit système assu­rant le verrouillage en position assemblée de ces éléments, aussi bien à plat qu'après mise en volume.The present invention relates to a system for assembling plate elements made of a semi-rigid material such as corrugated cardboard. It relates more particularly to a system of this type which can be applied to nested planar elements, capable, by pivoting, of being brought flat against each other, said system ensuring the locking in the assembled position of these elements, as well flat only after setting in volume.

De tels éléments peuvent être, notamment, des parties de croisillons pour casiers à bouteilles, qui sont constitués de plaques de carton ou de carton ondulé entaillées à in­tervalles réguliers sur une partie de leur hauteur par des fentes, dans lesquelles sont engagées les fentes correspon­dantes de plaques similaires, de manière à former un ensem­ble qui définit avec la caisse en carton dans laquelle il est logé une pluralité de logements identiques pour des bouteilles.Such elements can be, in particular, parts of crosspieces for bottle racks, which consist of cardboard or corrugated cardboard plates notched at regular intervals over part of their height by slots, in which the corresponding slots of similar plates, so as to form an assembly which defines with the cardboard box in which it is housed a plurality of identical housings for bottles.

Les croisillons peuvent être stockés à plat après assem­blage. Il est également fréquent qu'ils soient logés à l'avance dans les caisses américaines qu'ils équipent, en étant parfois solidaires par collage d'une face interne de ces caisses, et ce sont alors les caisses elles-mêmes qui sont stockées à plat avec les croisillons qu'elles contiennent.The braces can be stored flat after assembly. It is also common for them to be housed in advance in the American boxes they equip, sometimes being joined together by gluing an internal face of these boxes, and it is then the boxes themselves that are stored at flat with the braces they contain.

Il est donc important que, tant au cours de la mise en place des croisillons dans les caisses que lors de leur mise en volume, leurs éléments constitutifs ne risquent pas de se désolidariser les uns des autres.It is therefore important that, both during the installation of the crosspieces in the boxes and during their setting in volume, their constituent elements are not likely to dissociate from each other.

Il en est de même lorsque la caisse est pleine de bou­teilles,en particulier lorsque l'on utilise des croisillons du type dit "économique", dans lesquels les logements des croisillons ne protègent les bouteilles que jusqu'à leur épaulement.The same is true when the crate is full of bottles, especially when using braces of the so-called "economic" type, in which the housings of the braces protect the bottles only up to their shoulder.

Il est donc souhaitable que les éléments constitutifs du croisillon soient verrouillés, une fois assemblés, quelles que soient leurs positions relatives et quelles que soient les manipulations qu'on leur fait subir, au cours de leur mise en volume ou après celle-ci.It is therefore desirable that the components of the spider be locked, once assembled, whatever their relative positions and whatever handling they are subjected to, during their setting in volume or after it.

On a déjà proposé dans ce but (voir le brevet français n° 2 154 339 ou le brevet US n° 2 466 275), de verrouiller en position assemblée deux feuilles de carton présentant des entailles dans lesquelles elles sont mutuellement im­briquées, en donnant aux entailles de l'une des plaques un profil non rectiligne définissant une dent, que l'on peut engager dans une fente ou une découpe ménagée en position correspondante dans l'autre plaque.It has already been proposed for this purpose (see French Patent No. 2,154,339 or US Patent No. 2,466,275), to lock in the assembled position two sheets of cardboard having notches in which they are mutually nested, giving the notches of one of the plates a non-rectilinear profile defining a tooth, which can be engaged in a slot or a cut formed in the corresponding position in the other plate.

Un tel système assure un excellent verrouillage de deux plaques assemblées lorsqu'elles sont en position d'utili­sation, c'est-à-dire lorsqu'elles sont perpendiculaires l'une à l'autre. Par contre, lorsqu'elles sont repliées à plat, les dents peuvent très facilement sortir de leur logement, par simple coulissement des plaques au contact l'une de l'autre, et aucune sécurité n'est obtenue dans cette position.Such a system ensures excellent locking of two assembled plates when they are in the use position, that is to say when they are perpendicular to each other. On the other hand, when they are folded flat, the teeth can very easily come out of their housing, by simple sliding of the plates in contact with one another, and no security is obtained in this position.

La présente invention vise à remédier à ces inconvénients de la technique connue, en proposant un système d'assem­blage de deux éléments en carton ou en une matière semi-­rigide coopérant par imbrication de fentes, de forme particulière, pour verrouiller les éléments assem­blés, quel que soit l'angle que forment entre eux les­dits éléments et même lorsqu'ils sont repliés à plat l'un contre l'autre.The present invention aims to remedy these drawbacks of the known technique, by proposing a system for assembling two elements of cardboard or of a semi-rigid material cooperating by nesting of slots, of particular shape, to lock the assembled elements, whatever that is the angle that these elements form between them and even when they are folded flat against each other.

A cet effet, l'invention a pour objet un système d'assem­blage de deux éléments plans en une matière semi-rigide du type dans lequel chacun desdits éléments en plaques com­porte, à partir de l'un de ses bords, une fente dans une partie rectiligne au moins de laquelle l'autre élément est engagé, les parties rectilignes correspondantes des fentes des deux éléments en position assemblée étant dans le pro­longement l'une de l'autre, ce système étant caractérisé en ce que la fente de l'un desdits éléments a un profil tel qu'elle définit une partie formant un volet décalé latéra­lement par rapport à la partie rectiligne de ladite fente et articulé sur ledit élément par une ligne de pliage diri­gée obliquement par rapport à ladite partie rectiligne, et en ce que l'autre élément comporte une ouverture dans la­quelle ledit volet est engagé en position assemblée, ladite ouverture ayant une forme telle que, lorsque lesdits élé­ments assemblés sont disposés perpendiculairement l'un à l'autre, ledit volet peut pivoter librement autour de sa ligne de pliage sans rencontrer les bords de ladite ouver­ture, tandis que, lorsque lesdits éléments sont appliqués l'un contre l'autre en partie assemblée, après pivotement autour d'un axe défini par la direction desdites parties rectilignes, ledit volet ne peut pas pivoter librement au­tour de sa ligne de pliage sans venir en butée contre l'un des bords de ladite ouverture.To this end, the subject of the invention is a system for assembling two planar elements in a semi-rigid material of the type in which each of said plate elements comprises, from one of its edges, a slot in a rectilinear part at least of which the other element is engaged, the corresponding rectilinear parts of the slots of the two elements in the assembled position being in the extension of one another, this system being characterized in that the slot of one of said elements has a profile such that it defines a part forming a flap offset laterally with respect to the rectilinear part of said slot and articulated on said element by a fold line directed obliquely with respect to said rectilinear part, and in that the other element comprises an opening in which said flap is engaged in the assembled position, said opening having a shape such that, when said assembled elements are arranged perpendicular to each other, ledi t flap can pivot freely around its fold line without meeting the edges of said opening, while, when said elements are applied one against the other in part assembly, after pivoting around an axis defined by the direction of said rectilinear parts, said flap cannot pivot freely around its fold line without coming into abutment against one of the edges of said opening.

Les deux éléments pourront ainsi être assemblés dans une position dans laquelle ils sont perpendiculaires l'un à l'autre, en engageant de façon usuelle chacun desdits élé­ments dans la fente de l'autre élément. Ledit volet s'esca­mote en pivotant autour de sa ligne de pliage lorsqu'il rencontre une partie pleine de l'autre élément et, lors­qu'il se trouve en regard de la découpe de l'autre panneau, il pivote par élasticité en sens inverse autour de sa ligne de pliage et revient dans le plan de l'élément auquel il est attenant en traversant ladite découpe. Dans cette posi­tion, où les deux éléments de carton sont perpendiculaires l'un à l'autre avec le volet engagé dans la découpe asso­ciée,perpendiculairement au plan de cette découpe, le volet empêche les deux éléments de se désolidariser.The two elements can thus be assembled in a position in which they are perpendicular to each other, by customarily engaging each of said elements in the slot of the other element. Said flap retracts by pivoting around its fold line when it meets a solid part of the other element and, when it is opposite the cutout of the other panel, it pivots by elasticity in the opposite direction around its fold line and returns to the plane of the element to which it is attached by crossing said cut. In this position, where the two cardboard elements are perpendicular to each other with the flap engaged in the associated cut, perpendicular to the plane of this cut, the flap prevents the two elements from coming apart.

Si l'on fait alors pivoter les deux éléments par rapport à l'axe matérialisé par la direction générale de leurs fentes, pour les amener à plat l'un contre l'autre, la ligne de pliage servant d'articulation au volet sera d'un côté du panneau comportant l'ouverture, tandis qu'une par­tie de ce volet sera de l'autre côté dudit panneau, puisque le volet ne peut pas pivoter librement, dans cette posi­tion, autour de sa ligne de pliage. Dans cette position également, par conséquent, le volet restera engagé oblique­ment dans l'ouverture associée et les deux éléments seront donc dans tous les cas verrouillés en position assemblée.If the two elements are then pivoted relative to the axis materialized by the general direction of their slots, to bring them flat against each other, the fold line serving as an articulation for the flap will be d 'one side of the panel having the opening, while a part of this flap will be on the other side of said panel, since the flap cannot pivot freely, in this position, around its fold line. In this position also, therefore, the flap will remain engaged obliquely in the associated opening and the two elements will therefore in all cases be locked in the assembled position.

Bien entendu, chacun des éléments assemblés conformément à l'invention peut comprendre un volet destiné à être engagé dans une ouverture de l'autre élément et une ouverture des­tinée à recevoir un volet de l'autre élément.Of course, each of the elements assembled in accordance with the invention may comprise a flap intended to be engaged in an opening of the other element and an opening intended to receive a flap of the other element.

Un tel système est donc particulièrement bien adapté au verrouillage en position assemblée des éléments de croi­sillons pour casiers à bouteilles, car il ne modifie pas de façon sensible leur fabrication ou leur montage. On notera d'ailleurs qu'il y a autoblocage des éléments au cours du montage,le volet venant s'engager de lui-même dans l'ouver­ture associée. Une telle application à l'assemblage d'élé­ments de croisillons pour bouteilles du système selon l'in­vention constitue donc un autre objet de l'invention.Such a system is therefore particularly well suited to locking in the assembled position of the crosspiece elements for bottle racks, since it does not significantly modify their manufacture or their mounting. Note also that there is autoblocking of the elements during assembly, the shutter engaging itself in the associated opening. Another object of the invention is such an application to the assembly of cross-pieces for bottles of the system according to the invention.

De nombreuses formes pourront être données au volet et à la découpe associée. Le volet et la découpe pourront, par exemple, avoir un profil triangulaire, l'un des côtés du triangle étant constitué, pour le volet, par sa ligne de pliage et, pour la découpe, par un prolongement décalé de la partie rectiligne de la fente du panneau dans lequel elle est pratiquée. Avantageusement, la découpe aura une forme symétrique par rapport à la partie rectiligne de la­dite fente, afin que le volet puisse s'escamoter, par pivo­tement autour de sa ligne de pliage, indifféremment dans un sens ou dans l'autre avant de s'engager dans la découpe, lorsque l'on assemble les deux panneaux.Many shapes can be given to the shutter and the associated cutout. The shutter and the cut could, for example, have a triangular profile, one of the sides of the triangle being constituted, for the shutter, by its fold line and, for the cut, by an offset offset of the rectilinear part of the panel slot in which it is practiced. Advantageously, the cut will have a symmetrical shape with respect to the rectilinear part of said slot, so that the flap can be retracted, by pivoting around its fold line, indifferently in one direction or the other before engaging. in the cutout, when the two panels are assembled.

Le volet et la découpe pourront également avoir des profils curvilignes.The shutter and the cut can also have curvilinear profiles.

Dans une forme de réalisation préférée de l'invention, dans le panneau équipé dudit volet, une languette articulée sur ce panneau par une ligne de pliage sensiblement perpendi­culaire à la partie rectiligne de la fente sera prévue au-­dessous de l'extrémité inférieure de la découpe inférieure de cette fente, en vue d'amortir les chocs entre panneaux, lors de leur imbriquement, et d'assurer ainsi un position­nement adéquat du volet et de la découpe associée.In a preferred embodiment of the invention, in the panel equipped with said flap, a tongue articulated on this panel by a fold line substantially perpendicular to the rectilinear part of the slot will be provided below the lower end of the lower cutout of this slot, in order to absorb shocks between panels, during their overlapping, and thus ensure adequate positioning of the shutter and the associated cutout.

L'invention sera exposée ci-après plus en détail, en réfé­rence aux dessins annexés, sur lesquels:

The invention will be explained below in more detail, with reference to the accompanying drawings, in which:
  • Figures 1 and 2 are perspective views of two cardboard panels capable of being assembled in accordance with the invention;
  • Figures 3 and 4 are views on a larger scale, respectively, of the flap of one of these panels and the cutout of the other panel;
  • Figures 5 and 6 are perspective views of the panels of Figures 1 and 2, arranged perpendicular to each other, respectively during assembly and after assembly;
  • Figure 7 shows the two assembled panels, applied one against the other, after pivoting 90 ° relative to the position of Figures 5 and 6.
  • FIGS. 8 and 9 are perspective views illustrating the application of this system to a crosspiece for a bottle rack, shown respectively in the position of use and during folding flat.
  • Figure 10 is a variant of Figure 2, in a preferred embodiment of the invention.

Les panneaux de carton 1 et 2 représentés sur les figures 1 et 2 comprennent chacun, à partir d'un bord, une fente, respectivement 3 et 4, permettant de les assembler, en les imbriquant l'un dans l'autre, et de les faire pivoter après assemblage autour d'un axe matérialisé par la direction générale des fentes.The cardboard panels 1 and 2 shown in FIGS. 1 and 2 each comprise, from an edge, a slot, respectively 3 and 4, making it possible to assemble them, by nesting them one inside the other, and rotate them after assembly around an axis materialized by the general direction of the slots.

La fente 4 du panneau 2 est sensiblement rectiligne tandis que la fente 3 du panneau 1 comporte une partie sensible­ment rectiligne 5, de longueur égale à celle de la fente 4, dans le prolongement de laquelle se trouve en position assemblée. La partie 5 de la fente 3 est prolongée par des parties 6 et 7, délimitant un volet 8, articulé sur le panneau 1 par une ligne de pliage 9, disposée obliquement par rapport à la partie 5 de la fente 3.The slot 4 of the panel 2 is substantially rectilinear while the slot 3 of the panel 1 comprises a substantially rectilinear part 5, of length equal to that of the slot 4, in the extension of which is in the assembled position. Part 5 of the slot 3 is extended by parts 6 and 7, delimiting a flap 8, articulated on the panel 1 by a fold line 9, arranged obliquely relative to the part 5 of the slot 3.

Une découpe 10 est ménagée dans le panneau 2, dans une position telle qu'en position assemblée le volet 8 puisse y pénétrer librement, lorsque les panneaux sont assemblés, dans une position perpendiculaire l'un à l'autre. Cette découpe 10 a une forme telle que, lorsque les deux élé­ments 1 et 2 assemblés sont perpendiculaires l'un à l'autre (position de la figure 6), le volet 8 puisse pivoter libre­ment autour de la ligne de pliage 9, sans rencontrer les bords de la découpe 10, tandis que, lorsqu'ils sont assem­blés et appliqués l'un contre l'autre (position de la figure 7), le volet 8 ne puisse pas pivoter autour de la ligne 9 sans être arrêté par un ou des bords 10a de la découpe 10.A cutout 10 is provided in the panel 2, in a position such that in the assembled position the flap 8 can penetrate it freely, when the panels are assembled, in a position perpendicular to one another. This cutout 10 has a shape such that, when the two elements 1 and 2 assembled are perpendicular to each other (position in FIG. 6), the flap 8 can pivot freely around the fold line 9, without meeting the edges of the cutout 10, while, when they are assembled and applied one against the other (position in FIG. 7), the flap 8 cannot pivot around the line 9 without being stopped by one or more edges 10a of the cutout 10.

De nombreuses formes de volet et de découpe remplissent ces conditions. Dans le cas des dessins, le volet 8 a une forme triangulaire, tandis que la découpe 10 a un profil symétri­que par rapport à l'axe de la fente 4 et a la forme d'un quadrilatère formé par la juxtaposition de deux triangles identiques. C'est contre les dépouilles 10a formées par les côtés inférieurs de ce quadrilatère que vient buter le volet 8, lorsque les panneaux 1 et 2 sont appliqués à plat l'un contre l'autre. Naturellement, la base de ce quadri­latère pourrait avoir une forme curviligne, celle d'un arc de cercle par exemple, sans sortir du cadre de l'invention.Many forms of shutter and cutout meet these conditions. In the case of the drawings, the flap 8 has a triangular shape, while the cutout 10 has a symmetrical profile with respect to the axis of the slot 4 and has the shape of a quadrilateral formed by the juxtaposition of two identical triangles. It is against the bodies 10a formed by the lower sides of this quadrilateral that the shutter 8 abuts, when the panels 1 and 2 are applied flat against each other. Naturally, the base of this quadrilateral could have a curvilinear shape, that of an arc of a circle for example, without departing from the scope of the invention.

L'assemblage des panneaux 1 et 2 s'effectue de la manière illustrée par les figures 5 et 6. Les panneaux étant per­pendiculaires entre eux, on les engage respectivement de façon usuelle dans la fente 3 ou 4 de l'autre panneau. A mesure que progresse l'imbrication des panneaux, le volet 8 est repoussé par le panneau et pivote latéralement autour de la ligne de pliage 9, suivant la flèche F₁ (figure 5) pour s'escamoter, jusqu'à ce qu'il arrive en regard de la découpe 10. Du fait de son élasticité, il pivote alors en sens inverse autour de la ligne 9, suivant la flèche F₂, en pénétrant dans la découpe 10, pour revenir ainsi dans le plan du panneau 1 et verrouiller les panneaux en position assemblée (figure 6). Il y a donc auto-blocage des deux panneaux, sans qu'une intervention manuelle ou mécanique soit nécessaire pour engager le volet 8 dans la fente 10.The assembly of the panels 1 and 2 is carried out in the manner illustrated by FIGS. 5 and 6. The panels being perpendicular to each other, they are respectively engaged in the usual manner in the slot 3 or 4 of the other panel. As the interlocking of the panels progresses, the flap 8 is pushed back by the panel and pivots laterally around the fold line 9, along the arrow F₁ (FIG. 5) to retract, until it arrives opposite the cutout 10. Because of its elasticity, it then pivots in the opposite direction around the line 9, along the arrow F₂, entering the cutout 10, thus returning to the plane of the panel 1 and locking the panels in assembled position (figure 6). There is therefore self-locking of the two panels, without manual or mechanical intervention being necessary to engage the flap 8 in the slot 10.

Si l'on fait alors pivoter les deux panneaux autour de l'axe matérialisé par les parties des fentes 3 et 4 situées dans le prolongement l'une de l'autre pour les amener à plat l'un sur l'autre (figure 7), le volet 8 ne peut pas sortir de la découpe 10 en pivotant autour de la ligne de pliage 9, puisque sa pointe 11 rencontrait, en pivotant, le bord inférieur 10a de cette découpe. Il demeure donc engagé obliquement dans celle-ci et, même dans cette position de pliage à plat, les deux panneaux ne peuvent se désolida­riser l'un de l'autre.If we then rotate the two panels around the axis materialized by the parts of the slots 3 and 4 located in the extension of one another to bring them flat one on the other (Figure 7 ), the flap 8 cannot exit from the cutout 10 by pivoting around the fold line 9, since its tip 11 encountered, by pivoting, the lower edge 10a of this cutout. It therefore remains obliquely engaged in the latter and, even in this flat folding position, the two panels cannot separate from one another.

Bien entendu, chacun des panneaux 1 et 2 peut comprendre un volet et une ouverture pour recevoir le volet de l'autre panneau.Of course, each of the panels 1 and 2 may include a shutter and an opening for receiving the shutter from the other panel.

Comme on l'a dit ci-dessus, un tel système d'assemblage est donc particulièrement bien adapté au verrouillage en posi­tion assemblée des éléments d'un croisillon de casiers à bouteilles. Ceci apparaît clairement sur les figures 8 et 9, où les organes déjà décrits en relation avec les figures précédentes sont désignés par les mêmes chiffres de réfé­rences affectés de l'indice ' .As mentioned above, such an assembly system is therefore particularly well suited to locking in the assembled position the elements of a cross of bottle racks. This is clearly shown in FIGS. 8 and 9, where the members already described in relation to the preceding figures are designated by the same reference numbers assigned to the index '.

Le croisillon représenté sur ces figures comprend un pan­neau 2' assemblé conformément à l'invention avec deux pan­neaux parallèles 1' qui forment avec un élément de raccor­dement 12' un ensemble à section en U, pouvant, de façon connue en soi, être rendu solidaire de la paroi interne d'une caisse américaine par collage de l'élément 12' contre cette paroi. Dans le cas du dessin, l'élément 12' repré­sentant la base du U est parallèle au panneau 2', mais il pourrait aussi bien être perpendiculaire à cette paroi (comme schématisé en 12" sur la figure 8), pour être dis­posé au fond de la caisse, après mise en forme de celle-ci.The spider shown in these figures comprises a panel 2 'assembled in accordance with the invention with two parallel panels 1' which form with a connection element 12 'a U-section assembly, which can, in a manner known per se, be made integral of the internal wall of an American box by bonding of the element 12 'against this wall. In the case of the drawing, the element 12 'representing the base of the U is parallel to the panel 2', but it could as well be perpendicular to this wall (as shown diagrammatically in 12 "in FIG. 8), to be arranged at the bottom of the body, after formatting thereof.

La figure 10 illustre une forme de mise en oeuvre préférée de l'invention. Sur cette figure, qui est une variante de la figure 3, les éléments déjà décrits conservent les mêmes chiffres de référence.Figure 10 illustrates a preferred embodiment of the invention. In this figure, which is a variant of Figure 3, the elements already described retain the same reference numbers.

On remarquera toutefois qu'à l'extrémité inférieure de la partie 7 de la fente, une languette 14, découpée dans le panneau 1, est articulée sur celui-ci par une ligne de pliage 15 sensiblement perpendiculaire à la partie recti­ligne 5 de la fente 3. La raison en est que, dans la forme de réalisation représentée sur les figures 1 à 4, lorsque les panneaux 1 et 2 viennent s'encastrer les uns dans les autres à grande vitesse, le panneau 2, chutant dans la fente 3 du panneau 1, risque d'endommager et même de déchi­rer sous le choc l'extrémité inférieure de la partie 7 de la découpe. Dans cette éventualité, le panneau 2 risque d'être décalé vers le bas par rapport au panneau 1 et la languette 8 de ne pas être avec précision dans la position adéquate par rapport à la découpe 10 pour assurer un ver­rouillage des panneaux lorsqu'ils sont assemblés.It will be noted however that at the lower end of the part 7 of the slot, a tongue 14, cut out from the panel 1, is articulated on the latter by a line of folding 15 substantially perpendicular to the straight part 5 of the slot 3. The reason is that, in the embodiment shown in Figures 1 to 4, when the panels 1 and 2 are recessed into each other at large speed, the panel 2, falling into the slot 3 of the panel 1, risks damaging and even tearing under the impact the lower end of the part 7 of the cutout. In this event, the panel 2 may be shifted downward relative to the panel 1 and the tongue 8 may not be precisely in the correct position relative to the cutout 10 to ensure locking of the panels when they are assembled.

En prévoyant une languette pivotante 14 au-dessous de l'ex­trémité inférieure de la découpe 7, cette languette amor­tira en pivotant autour de la ligne 15 le choc exercé par la chute du panneau 1 et éliminera les risques de déchi­rure. En outre, en reprenant par élasticité sa position initiale par pivotement en sens inverse autour de la ligne 15, la languette 14 sollicitera vers le haut le panneau et le ramènera ainsi dans une position propre à permettre le verrouillage à plat des panneaux associés.By providing a pivoting tab 14 below the lower end of the cutout 7, this tab will absorb, by pivoting around the line 15, the shock exerted by the fall of the panel 1 and will eliminate the risks of tearing. In addition, resuming by elasticity its initial position by pivoting in the opposite direction around the line 15, the tongue 14 will urge the panel upwards and thus bring it back to a position suitable for allowing the associated panels to be locked flat.

L'invention apporte donc un système très simple, facile à réaliser et à monter, pour le verrouillage en toutes posi­tions de deux éléments plans assemblés par imbrication l'un dans l'autre d'un système de fentes.The invention therefore provides a very simple system, easy to make and to assemble, for locking in any position of two planar elements assembled by nesting one inside the other of a system of slots.
