  • the furniture boxes are formed by the assembly of panels, usually edge to edge.
  • the assembly means of panels are very diverse ranging from complex assembly forms used in carpentry to a more simple assembly edge to edge, glued and reinforced if necessary by points and staples.
  • the joints glued edge-to-edge often use spacers, such as tongues, tabs, placed in two complementary grooves and glued assemblies, (for example slats of elliptical or rectangular shape diffused under the trademark "Lamello").
  • the present invention aims to develop a furniture box formed by the assembly of panels and whose realization of the assembly at the corners of the box, can be done in a simple manner, with a guaranteed result and without requiring special knowledge in the field of carpentry.
  • the invention relates to a furniture box of the type defined above, characterized in that

  • the furniture box according to the invention assembles in a particularly simple manner since it is sufficient to join the various panels, for example the four panels constituting the parallelepipedal box.
  • the box according to the invention does not require any assembly accessories said hardware, such as screws, pins, eccentric that complicate the packaging and preparation in the factory and also the assembly by the customer who, in principle, is not a specialist in carpentry assembly techniques.
  • the assembly is done by simple casing, also the assembly angles (for example 90 °) are guaranteed because of the simple meeting of the panels.
  • the meeting of the panels may be corrected, in a very simple manner so that the front and rear faces of the panels are perfectly aligned.
  • the box has a bottom housed in a groove made near the rear edge of each of the panels, the assembly is even simpler since the panels are guided in their assembly also by the bottom of the box, engaged in the grooves. The introduction of the locking tabs in the box thus assembled with its bottom, completes the assembly.
  • the assembly is just as simple by joining the panels, then locking their assembly to then put in place the bottom in the rabbet and which covers the ends of the locking tabs.
  • the locking grooves open on only one side of the panels.
  • the locking grooves preferably open on the back side of the panels, that is to say from the rear of the box so that the front face of the box reveals only the line of junction between the bastard tongue and its housing without revealing the channel formed by the meeting of the two locking grooves at each corner.
  • the aspect of the furniture in frontage is of this fact net.
  • the locking grooves can occupy the entire length of the edge of the panels and lead to the front side.
  • the channel can also receive in this case a decorative element which underlines the corner of the furniture in front.
  • the locking tab may have a length greater than the length of the channel if it must protrude forward or a length less than the length of the channel to allow the channel to open freely on the front face and possibly receive an element fixing, such as a pin, at the rear of an element decorating the front face of the box.

  • the tongue is. thus tightly engaged in the channel and strengthens the assembly by locking it and compensating for any play.
  • the locking tab ends at the rear by a tab forming a support or a limit stop engagement engagement of the tongue in the channel.
  • This tab facilitates the introduction of the tongue into the channel especially if the section of the tongue is adapted closely to that of the channel thus increasing the bearing surface,
  • the locking grooves are of rectangular section and the locking tongue has a section at most equal to the clearance, that of a groove to be placed in this groove before assembling the panels without exceeding the groove to be then pushed to the junction of the two grooves when the assembly of the panels is completed so as to lock their assembly.
  • This tongue can be placed in the locking groove after manufacture of the panel so that the panels of a furniture box can be packaged and packaged without worrying about locking tabs that the end user will find and already installed, it will suffice after assembling the panels, pushing each locking tab to also enter the other groove forming the channel.
  • This movement can be done simply using a rod slipped into the groove.

When the panels (10, 20) are assembled, the joining of the grooves (16, 26) forms a channel receiving a locking tongue that locks the tongue in the groove.

Description

« Caisson de meuble »  "Furniture cabinet"
Domaine de l'invention  Field of the invention
La présente invention se rapporte à un caisson de meuble formé de panneaux assemblés bord à bord selon un assemblage à ramure et languette bâtarde dans lequel,  The present invention relates to a furniture box formed of panels assembled edge to edge according to a joint with bastard tongue and tongue in which,
- un premier et un second panneau sont assemblés par le chant du premier panneau venant contre le bord intérieur du deuxième panneau formant ainsi un dièdre, le premier panneau ayant une première orientation et le second panneau ayant une seconde orientation dans le plan perpendiculaire à la direction de l'arête du dièdre formé par l'assemblage.  a first and a second panel are assembled by the edge of the first panel coming against the inner edge of the second panel thus forming a dihedron, the first panel having a first orientation and the second panel having a second orientation in the plane perpendicular to the direction; of the edge of the dihedron formed by the assembly.
Etat de la technique State of the art
Les caissons de meuble sont formés par l'assemblage de panneaux, en général bord à bord.  The furniture boxes are formed by the assembly of panels, usually edge to edge.
Les moyens d'assemblage de panneaux sont très diverses allant de formes d'assemblages complexes utilisées en menuiserie jusqu'à un assemblage plus simple bord à bord, collé et renforcé le cas échéant par des pointes et des agrafes. Les assemblages collés bord à bord utilisent souvent des éléments intercalaires, tels que des languettes, des la- melles, placées dans deux rainures complémentaires et assemblées collées, (par exemple des lamelles de forme elliptique ou rectangulaire diffusées sous la marque "Lamello").  The assembly means of panels are very diverse ranging from complex assembly forms used in carpentry to a more simple assembly edge to edge, glued and reinforced if necessary by points and staples. The joints glued edge-to-edge often use spacers, such as tongues, tabs, placed in two complementary grooves and glued assemblies, (for example slats of elliptical or rectangular shape diffused under the trademark "Lamello").
Mais ces modes d'assemblage nécessitent un savoir-faire pour réussir un bon assemblage.  But these modes of assembly require a know-how to succeed a good assembly.
But de l'invention Purpose of the invention
La présente invention a pour but de développer un caisson de meuble formé par l'assemblage de panneaux et dont la réalisation de l'assemblage aux coins du caisson, puisse se faire de manière simple, avec un résultat garanti et sans nécessiter de connaissances particulières dans le domaine de la menuiserie.  The present invention aims to develop a furniture box formed by the assembly of panels and whose realization of the assembly at the corners of the box, can be done in a simple manner, with a guaranteed result and without requiring special knowledge in the field of carpentry.
Exposé et avantages de l'invention  Description and advantages of the invention
A cet effet l'invention a pour objet un caisson de meuble du type défini ci-dessus, caractérisé en ce que  For this purpose the invention relates to a furniture box of the type defined above, characterized in that
- le premier panneau comporte sur son chant, en bordure de son côté intérieur, une languette bâtarde d'assemblage, laissant une surface d'appui de chant, et  the first panel has on its edge, on the edge of its inner side, a bastard assembly tongue, leaving a singing support surface, and
- une rainure de verrouillage à la base de la languette le long du bord intérieur de ce panneau. le second panneau comporte le long de son bord intérieur un logement de forme complémentaire à celle du chant du premier panneau avec d'une part une rainure d'assemblage, longitudinale, de forme complémentaire à celle de la languette, et d'autre part une surface d'appui ex- térieure au-delà de la rainure pour recevoir la surface d'appui de chant de l'autre panneau, - A locking groove at the base of the tongue along the inner edge of this panel. the second panel comprises along its inner edge a housing of complementary shape to that of the edge of the first panel with on the one hand a longitudinal assembly groove, complementary in shape to that of the tongue, and on the other hand a outer bearing surface beyond the groove to receive the edge-bearing surface of the other panel,
une rainure de verrouillage dans le second panneau débouchant dans le logement d'assemblage dans une position complémentaire à celle de la rainure de verrouillage du premier panneau lorsque les deux pan- neaux sont assemblés, la languette bâtarde du premier panneau venant dans le logement d'assemblage du second pannea^i et la surface d'appui de chant du premier panneau étant appliquée contre la surface d'appui extérieure du deuxième panneau, les rainures de verrouillage se complétant pour former un canal recevant une languette de verrouil- lage, la réunion de la languette bâtarde et de la rainure d'assemblage assurant, le blocage dans la seconde direction et la languette de verrouillage bloquant l'assemblage dans la première direction.  a locking groove in the second panel opening into the assembly housing in a position complementary to that of the locking groove of the first panel when the two panels are assembled, the bastard tongue of the first panel coming into the housing of assembling the second panel and the edge-pressing surface of the first panel being applied against the outer bearing surface of the second panel, the locking grooves completing to form a channel receiving a locking tab, the assembly the bastard tongue and the assembly groove ensuring the locking in the second direction and the locking tab blocking the assembly in the first direction.
Le caisson de meuble selon l'invention s'assemble d'une manière particulièrement simple puisqu'il suffit de réunir les différents panneaux, par exemple les quatre panneaux constituant le caisson paral- lélépipédique. Le caisson selon l'invention ne nécessite aucun accessoire d'assemblage dit de quincaillerie, tel que vis, tourillon, excentrique qui compliquent le conditionnement et la préparation en usine et aussi l'assemblage par le client qui, en principe, n'est pas un spécialiste des tech- niques d'assemblage en menuiserie.  The furniture box according to the invention assembles in a particularly simple manner since it is sufficient to join the various panels, for example the four panels constituting the parallelepipedal box. The box according to the invention does not require any assembly accessories said hardware, such as screws, pins, eccentric that complicate the packaging and preparation in the factory and also the assembly by the customer who, in principle, is not a specialist in carpentry assembly techniques.
En revanche selon l'invention l'assemblage se fait par simple emboîtage, aussi les angles d'assemblage (par exemple 90°) sont garantis du fait de la simple réunion des panneaux. En cas d'erreur d'alignement le long de la ligne d'assemblage, la réunion des panneaux peut être éventuellement corrigée, de manière très simple de façon que les faces avant et les faces arrière des panneaux soient parfaitement alignées.  On the other hand according to the invention the assembly is done by simple casing, also the assembly angles (for example 90 °) are guaranteed because of the simple meeting of the panels. In the event of misalignment along the assembly line, the meeting of the panels may be corrected, in a very simple manner so that the front and rear faces of the panels are perfectly aligned.
Puis, il suffit de verrouiller les assemblages en introduisant, la languette de verrouillage dans le canal formé par la réunion des deux rainures de verrouillage au niveau de chaque coin d'assemblage.  Then, simply lock the assemblies by introducing the locking tab into the channel formed by the union of the two locking grooves at each assembly corner.
Si le caisson comporte un fond logé dans une rainure réalisée près du bord arrière de chacun des panneaux, l'assemblage est encore plus simple puisque les panneaux sont guidés dans leur assemblage également par le fond du caisson, engagé dans les rainures. L'introduction des languettes de verrouillage dans le caisson ainsi assemblé avec son fond, termine l'ensemble. If the box has a bottom housed in a groove made near the rear edge of each of the panels, the assembly is even simpler since the panels are guided in their assembly also by the bottom of the box, engaged in the grooves. The introduction of the locking tabs in the box thus assembled with its bottom, completes the assembly.
Dans le cas d'un caisson avec un fond logé dans une feuillure réalisée le long du bord arrière des panneaux, l'assemblage se fait tout aussi simplement en réunissant les panneaux, puis en verrouillant leur assemblage pour ensuite mettre en place le fond dans la feuillure et qui couvre les extrémités des languettes de verrouillage.  In the case of a box with a bottom housed in a rabbet made along the rear edge of the panels, the assembly is just as simple by joining the panels, then locking their assembly to then put in place the bottom in the rabbet and which covers the ends of the locking tabs.
Suivant une caractéristique avantageuse, les rainures de verrouillage débouchent sur un côté seulement des panneaux. Les rai- nures de verrouillage débouchent de préférence du côté arrière des panneaux, c'est-à-dire de l'arrière du caisson de sorte que la face avant du caisson ne laisse apparaître que la ligne de jonction entre la languette bâtarde et son logement sans faire apparaître le canal formé par la réunion des deux rainures de verrouillage au niveau de chaque coin. L'aspect du meuble en façade est de ce fait net.  According to an advantageous characteristic, the locking grooves open on only one side of the panels. The locking grooves preferably open on the back side of the panels, that is to say from the rear of the box so that the front face of the box reveals only the line of junction between the bastard tongue and its housing without revealing the channel formed by the meeting of the two locking grooves at each corner. The aspect of the furniture in frontage is of this fact net.
Toutefois, suivant une caractéristique avantageuse, si pour des raisons d'esthétique, l'apparition du débouché du canal en face avant, est voulue, les rainures de verrouillage peuvent occuper toute la longueur du bord des panneaux et déboucher sur le côté avant. Le canal peut éga- lement recevoir dans ce cas un élément décoratif qui souligne le coin du meuble en façade.  However, according to an advantageous characteristic, if for aesthetic reasons, the appearance of the outflow of the channel in the front face, is desired, the locking grooves can occupy the entire length of the edge of the panels and lead to the front side. The channel can also receive in this case a decorative element which underlines the corner of the furniture in front.
Dans ce cas, la languette de verrouillage pourra avoir une longueur supérieure à la longueur du canal si elle doit dépasser à l'avant ou une longueur inférieure à la longueur du canal pour laisser le canal déboucher librement en face avant et recevoir éventuellement, un élément de fixation, tel qu'une broche, à l'arrière d'un élément décorant la face avant du caisson.  In this case, the locking tab may have a length greater than the length of the channel if it must protrude forward or a length less than the length of the channel to allow the channel to open freely on the front face and possibly receive an element fixing, such as a pin, at the rear of an element decorating the front face of the box.
Suivant une autre caractéristique avantageuse, les rainures de verrouillage ont une section rectangulaire et la languette de verrouillage a une section rectangulaire égale, au jeu près, à celle du canal formé par la réunion des deux rainures de verrouillage,  According to another advantageous characteristic, the locking grooves have a rectangular section and the locking tongue has a rectangular section equal, with the clearance, to that of the channel formed by the union of the two locking grooves,
La languette est. ainsi engagée étroitement, dans le canal et renforce l'assemblage en le verrouillant et en compensant un éventuel jeu.  The tongue is. thus tightly engaged in the channel and strengthens the assembly by locking it and compensating for any play.
Suivant une autre caractéristique avantageuse, la languette de verrouillage se termine à l'arrière par une patte formant un appui ou une butée de fin de course d'engagement de la languette dans le canal. Cette patte facilite l'introduction de la languette dans le canal surtout si la section de la languette est adaptée étroitement à celle du canal en augmentant ainsi la surface d'appui, According to another advantageous characteristic, the locking tab ends at the rear by a tab forming a support or a limit stop engagement engagement of the tongue in the channel. This tab facilitates the introduction of the tongue into the channel especially if the section of the tongue is adapted closely to that of the channel thus increasing the bearing surface,
Suivant une autre caractéristique avantageuse, les rainures de verrouillage sont de section rectangulaire et la languette de verrouillage a une section au plus égale, au jeu près, à celle d'une rainure pour être placée dans cette rainure avant l'assemblage des panneaux sans dépasser de la rainure pour être ensuite poussée à cheval de la jonction des deux rainures lorsque l'assemblage des panneaux est terminé de façon à verrouiller leur assemblage.  According to another advantageous feature, the locking grooves are of rectangular section and the locking tongue has a section at most equal to the clearance, that of a groove to be placed in this groove before assembling the panels without exceeding the groove to be then pushed to the junction of the two grooves when the assembly of the panels is completed so as to lock their assembly.
Cette languette peut être placée dans la rainure de verrouillage après la fabrication du panneau de sorte que les panneaux d'un caisson de meuble peuvent être conditionnés et emballés sans se préoccuper des languettes de verrouillage que l'utilisateur final trouvera ainsi déjà installées, il suffira après l'assemblage des panneaux, de repousser chaque languette de verrouillage pour la faire également pénétrer dans l'autre rainure formant le canal. Ce mouvement peut se faire simplement à l'aide d'une tige glissée dans la rainure. Cette forme de réalisation a l'avantage de garantir que la languette de verrouillage occupe toute la longueur de la rainure et qu'elle ne risque pas de se bloquer avant d'atteindre l'extrémité du canal, au cas où une aspérité constituerait un obstacle accidentel à la progression de la languette le long du canal.  This tongue can be placed in the locking groove after manufacture of the panel so that the panels of a furniture box can be packaged and packaged without worrying about locking tabs that the end user will find and already installed, it will suffice after assembling the panels, pushing each locking tab to also enter the other groove forming the channel. This movement can be done simply using a rod slipped into the groove. This embodiment has the advantage of ensuring that the locking tongue occupies the entire length of the groove and that it will not lock before reaching the end of the channel, in case an asperity would be an obstacle accidental to the progression of the tongue along the channel.
Suivant une autre caractéristique avantageuse, dans le cas d'un caisson muni d'un fond logé dans une rainure périphérique réalisée près du bord de chacun des panneaux, le fond comporte une découpe près de ses coins pour laisser dégagé le canal formé par les rainures,  According to another advantageous characteristic, in the case of a box provided with a bottom housed in a peripheral groove formed near the edge of each of the panels, the bottom has a cut-out near its corners to allow the channel formed by the grooves to be disengaged. ,
Cette réalisation permet d'adapter étroitement les dimensions du fond aux dimensions en hauteur et en largeur de remplacement défini par les rainures périphériques destinées à le recevoir, de manière à ce que le fond soit adapté étroitement à la dimension de la forme définie par les rainures.  This embodiment makes it possible to closely adapt the dimensions of the bottom to the dimensions in height and replacement width defined by the peripheral grooves intended to receive it, so that the bottom is adapted closely to the dimension of the shape defined by the grooves. .
Suivant une caractéristique particulièrement avantageuse, la languette de verrouillage est terminée par un organe de verrouillage accroché à l'extrémité du dièdre du caisson formé par l'assemblage de deux panneaux en s 'appuyant sur le chant et en se logeant dans la rainure des panneaux recevant les bords du fond pour immobiliser la languette de verrouillage. Cet organe de verrouillage permet de caler la languette de verrouillage et d'éviter que celle-ci ne dépasse de l'arrière du caisson sous l'effet des mouvements de vibration ou autres auxquels le caisson peut être soumis, L'organe de verrouillage a également l'avantage de caler le fond dans la rainure périphérique des parois pour éviter une éventuelle vibration du fond. According to a particularly advantageous characteristic, the locking tab is terminated by a locking member hooked to the end of the dihedral of the box formed by the assembly of two panels by pressing on the edge and housing in the groove of the panels receiving the edges of the bottom to immobilize the locking tab. This locking member makes it possible to wedge the locking tab and to prevent it from protruding from the rear of the box under the effect of vibration or other movements to which the box can The locking member also has the advantage of wedging the bottom in the peripheral groove of the walls to prevent possible vibration of the bottom.
Cette languette de verrouillage munie d'un tel organe de verrouillage s'installe simplement par une légère déformation de l'organe de verrouillage par rapport à la languette pour le faire passer sur le côté intérieur des surfaces du dièdre formé par la jonction des deux panneaux au niveau du coin puis laisser revenir l'organe de verrouillage en appui contre les faces intérieures, contre le dessus du caisson (en général le côté arrière) et dans la rainure périphérique.  This locking tongue provided with such a locking member is simply installed by a slight deformation of the locking member relative to the tongue to pass on the inner side of the surfaces of the dihedron formed by the junction of the two panels at the corner then let the locking member bear against the inner faces, against the top of the box (usually the back side) and in the peripheral groove.
Suivant une caractéristique particulièrement avantageuse, l'organe de verrouillage comporte une grande base en forme d'êquerre pour s'appuyer à plat, sur le chant des panneaux à leur jonction formant le dièdre d'assemblage, cette grande base solidaire de la languette de verrouillage étant prolongée par une partie de liaison en forme de dièdre venant se caler contre la face inférieure de la jonction en forme de dièdre des panneaux et portant une petite base avec des lamelles d'accrochage, en saillie, venant dans la rainure périphérique recevant les bords du fond. Cette forme de réalisation de l'organe de verrouillage assure un excellent calage de cet organe contre le côté intérieur des deux panneaux à leur jonction.  According to a particularly advantageous characteristic, the locking member comprises a large base-shaped bracket to rest flat on the edge of the panels at their junction forming the dihedral assembly, this large base secured to the tongue of locking being prolonged by a dihedral shaped connecting portion coming to wedge against the underside of the dihedral junction of the panels and carrying a small base with projecting hooking slats, coming in the peripheral groove receiving the bottom edges. This embodiment of the locking member ensures an excellent wedging of this member against the inner side of the two panels at their junction.
Suivant une autre caractéristique avantageuse, la petite base de forme triangulaire forme un fond dans l'intérieur du dièdre de la partie de liaison et comporte une encoche de manœuvre. Cette encoche permet d'introduire l'extrémité d'un outil formant levier tel que l'extrémité d'un tournevis dans l'encoche pour légèrement basculer ou déformer la petite base de l'organe de verrouillage et extraire les lamelles de verrouillage de la rainure périphérique des deux panneaux pour ensuite tirer facilement l'organe de verrouillage avec la languette de verrouillage.  According to another advantageous characteristic, the small triangular base forms a bottom in the interior of the dihedral of the connecting portion and comprises a maneuvering notch. This notch allows to introduce the end of a lever forming tool such as the end of a screwdriver in the notch to slightly tilt or deform the small base of the locking member and extract the locking slats of the peripheral groove of the two panels to then easily pull the locking member with the locking tab.
Bien que cette extraction soit alors simple, elle ne détériore en rien l'excellent accrochage de l'organe de verrouillage appuyé sur le chant des panneaux et pris dans la raimire recevant les bords du fond du caisson.  Although this extraction is simple, it does not deteriorate in any way the excellent attachment of the locking member pressed against the edge of the panels and caught in the raimire receiving the edges of the bottom of the box.
Suivant une autre caractéristique avantageuse, la grande base déborde de la partie de liaison en forme de dièdre d'une largeur correspondant à la largeur de la surface d'appui du décrochement réalisé dans le chant des panneaux. La grande base de l'organe de verrouillage comporte avantageusement une encoche sensiblement au droit de l'encoche de la, petite base pour recevoir l'outil formant levier et éviter que celui-ci ne glisse sur le grand côté de la grande base. According to another advantageous characteristic, the large base protrudes from the dihedral shaped connecting portion of a width corresponding to the width of the bearing surface of the recess made in the edge of the panels. The large base of the locking member advantageously comprises a notch substantially to the right of the notch of the small base to receive the lever tool and prevent it from slipping on the long side of the large base.
Avantageusement, l'organe de verrouillage a une forme symétrique par rapport au plan bi- secteur de la jonction des deux panneaux contre lesquels il s'applique.  Advantageously, the locking member has a symmetrical shape with respect to the two-sector plane of the junction of the two panels against which it is applied.
Suivant une autre caractéristique avantageuse, la languette de verrouillage est fractionnable poiir s'adapter à la profondeur du meuble et en particulier, la languette est subdivisée par des réductions locales de section délimitant des segments, en particulier des segments de longueurs différentes pour ne fabriquer qu'un type de languette et l'adapter à la profondeur des meubles ou caissons par simple enlèvement d'un ou plusieurs segments.  According to another advantageous characteristic, the locking tab is divisible to adapt to the depth of the piece of furniture and in particular, the tongue is subdivided by local sectional reductions delimiting segments, in particular segments of different lengths to manufacture only a type of tongue and adapt it to the depth of the furniture or boxes by simple removal of one or more segments.

L'invention a pour objet un caisson de meuble formé de panneaux assemblés bord à bord selon un assemblage à rainure et languette bâtarde, ici un caisson parallélêpipédique.  The invention relates to a furniture box formed of panels assembled edge to edge according to an assembly with groove and bastard tongue, here a parallelepiped box.
La figure 1 montre la région d'assemblage de deux panneaux 10, 20 selon l'invention représentatif de l'assemblage de quatre panneaux du caisson.  Figure 1 shows the assembly region of two panels 10, 20 according to the invention representative of the assembly of four panels of the box.
Un caisson est en général formé de quatre côtés, deux côtés latéraux, un dessus, un dessous et un fond. Mais l'invention ne se limite pas à une telle structure parallélêpipédique dont les panneaux sont à i'équerre. L'angle entre deux côtés peut être différent de 90° et les panneaux peuvent être assemblés avec des angles à 120° ou à 135° pour des sections octogonales ou hexagonales. De tels caissons peuvent être consti- tutifs d'un ensemble modulaire ou être des éléments utilisés individuellement. Les caissons peuvent être orientés comme cela est généralement le cas avec les arêtes horizontales, mais aussi avec des arêtes verticales pour former par exemple des piêtements de table, notamment de tables basses ou de sièges. A caisson is generally formed of four sides, two lateral sides, a top, a bottom and a bottom. But the invention is not limited to such a parallelepipedal structure whose panels are at equilibrium. The angle between two sides can be different from 90 ° and the panels can be assembled with 120 ° or 135 ° angles for octagonal or hexagonal sections. Such boxes can be made of a modular set or be used individually. The boxes can be oriented as is generally the case with the horizontal edges, but also with vertical edges to form for example tabletops, including coffee tables or seats.
Les panneaux 10, 20 ont une face intérieure 10a, 20a et une face extérieure 10b, 20b,  The panels 10, 20 have an inner face 10a, 20a and an outer face 10b, 20b,
Le premier panneau 10 comporte une languette bâtarde 1 1, c'est-à-dire située dans le prolongement du côté intérieur 10a du panneau 10. Cette languette 1 1 s'étend sur toute la longueur du panneau 10 et forme une surface avant 12 et deux surfaces d'appui latérales 13, 14 dont l'une rejoint une surface d'appui de chant 15. Le côté intérieur 100 du premier panneau 10, à la base de la languette bâtarde 1 1 , comporte une rainure de verrouillage 16 parallèle au chant.  The first panel 10 has a bastard tongue 1 1, that is to say located in the extension of the inner side 10a of the panel 10. This tongue 1 1 extends over the entire length of the panel 10 and forms a front surface 12 and two lateral bearing surfaces 13, 14, one of which joins an edge bearing surface 15. The inner side 100 of the first panel 10, at the base of the bastard tongue 11, has a parallel locking groove 16 singing.
Le second panneau 20 comporte près de son bord, sur le côté intérieur 20a, un logement ou découpe de forme complémentaire à celle du chant du premier panneau, c'est-à-dire un logement formant la ramure d'assemblage 21 destinée à recevoir la languette bâtarde 1 1 et au- delà de la ramure d'assemblage, une surface d'appui intérieure 25,  The second panel 20 has near its edge, on the inner side 20a, a housing or cut complementary shape to that of the edge of the first panel, that is to say a housing forming the assembly groove 21 for receiving the bastard tongue 1 1 and beyond the assembly groove, an inner bearing surface 25,
La ramure d'assemblage 21 est bordée d'une grande surface 23 d'appui, formé de deux parties 23a, 23b et d'une petite surface d'appui 24.  The assembly groove 21 is bordered by a large bearing surface 23 formed of two parts 23a, 23b and a small bearing surface 24.
La grande surface d'appui 23 est munie d'une rainure de verrouillage 26 dans une position homologue à celle de la rainure de verrouillage 16 du premier panneau 10 lorsque les deux panneaux 10, 20 sont réunis, la languette bâtarde 1 1 étant introduite à fond dans la rainure d'assemblage 21 et la surface d'appui de chant 15 du premier panneau 10 venant contre la surface d'appui intérieure 25 du second panneau 20.  The large bearing surface 23 is provided with a locking groove 26 in a position homologous to that of the locking groove 16 of the first panel 10 when the two panels 10, 20 are joined, the bastard tongue 1 1 being introduced to bottom in the assembly groove 21 and the abutment surface 15 of the first panel 10 against the inner bearing surface 25 of the second panel 20.
Dans cette position assemblée représentée à la figure 2, les deux rainures de verrouillage 16, 26 se rejoignent et forment un canal 30 parallèle à l'axe d'assemblage et recevant une languette de verrouillage 40.  In this assembled position shown in FIG. 2, the two locking grooves 16, 26 meet and form a channel 30 parallel to the assembly axis and receiving a locking tongue 40.
Les rainures de verrouillage 16, 26 des deux panneaux 10, 20 sont de préférence arrêtées juste avant l'extrémité des deux panneaxax 10, 20, mais débouchant par l'autre extrémité des panneaux. Cela permet d'introduire une languette de verrouillage 40 maïs évite que celle-ci ne dépasse d'un côté de l'assemblage (celui en-dessous du plan de la figure 1} de façon que la forme des deux rainures d'assemblage 16, 26 n'apparaît pas sur la tranche des deux panneaux assemblés 10, 20. The locking grooves 16, 26 of the two panels 10, 20 are preferably stopped just before the end of the two panneaxax 10, 20, but opening through the other end of the panels. This makes it possible to introduce a locking tab 40 corn avoids that it exceeds one side of the assembly (the one below the plane of Figure 1} so that the shape of the two assembly grooves 16, 26 does not appear on the edge of the two assembled panels 10, 20.
Selon les figures 1 et. 2, les deux panneaux 10, 20 une fois assemblés forment un dièdre dont l'arête est la direction de l'assemblage.  According to Figures 1 and. 2, the two panels 10, 20 once assembled form a dihedral whose edge is the direction of assembly.
Pour faciliter la description, le premier panneau 10 a une orientation X et le second panneau 20 a une orientation Y, ces orientations étant prises dans le plan perpendiculaire à l'arête du dièdre formé, qui est ici le plan constitué de la. feuille du dessin de la figure 1.  To facilitate the description, the first panel 10 has an orientation X and the second panel 20 has an orientation Y, these orientations being taken in the plane perpendicular to the edge of the formed dihedron, which is here the plane consisting of the. drawing sheet of Figure 1.
L'assemblage de la languette bâtarde 1 1 dans la rainure d'assemblage 21 se fait dans la direction Y et le verrouillage de cet assemblage par la languette 40 introduite dans le canal 30 qui est la réunion des deux ramures d'assemblage 16, 26, réalise le verrouillage dans la direction X.  The assembly of the bastard tongue 1 1 in the assembly groove 21 is in the direction Y and the locking of this assembly by the tongue 40 introduced into the channel 30 which is the union of the two assembly branches 16, 26 , performs locking in the X direction.
La figure 1 montre également que la surface d'appui intérieure 25 du second panneau 20 est en retrait de la distance R par rapport au plan du côté intérieur 20a du panneau 20. Réciproquement, la surface d'appui de chant 15 du premier panneau 10 est avancée de la distance A de sorte que la languette bâtarde 1 1 est plus courte que la languette bâtarde connue.  FIG. 1 also shows that the internal bearing surface 25 of the second panel 20 is set back from the distance R with respect to the plane of the inner side 20a of the panel 20. Conversely, the abutment surface 15 of the first panel 10 is advanced from the distance A so that the bastard tongue 1 1 is shorter than the bastard tongue known.
Les figures 3A, 3B montrent schématiquement la réalisation de la structure d'assemblage du panneau 20 et de sa rainure d'assemblage 21 avec sa rainure de verrouillage 26.  FIGS. 3A, 3B schematically show the realization of the assembly structure of the panel 20 and its assembly groove 21 with its locking groove 26.
Selon ce mode de réalisation, on forme d'abord la rainure d'assemblage 21 avec une fraise FR1 (figure 3A) la fraise tournant autour d'un axe Yl -Yl parallèle à la direction Y en enlevant également la partie devant la surface d'appui intérieure 25 pour former la partie en retrait.  According to this embodiment, the assembly groove 21 is first formed with a milling cutter FR1 (FIG. 3A), the milling cutter rotating around a Y1-Y1 axis parallel to the Y direction while also removing the part in front of the milling surface. inner bearing 25 to form the recessed portion.
Ensuite, avec une fraise F*R2 tournant autour d'un axe XI- XI (parallèle à l'axe X-X), on passe la surface d'appui intérieure 25 et on fraise la rainure de verrouillage 26. Then, with a milling cutter F * R2 rotating about an axis XI-XI (parallel to the axis XX), passing the inner bearing surface 25 and milling the locking groove 26.
La figure 4 montre un exemple de languette de verrouillage 40 de section rectangulaire, d'extrémité avant 41 en pointe et ayant à son extrémité arrière une patte 42 servant d'appui et de butée d'enfoncement, La patte 42 sert également au démontage du caisson pour faciliter l'extraction de la languette.  FIG. 4 shows an example of a locking tab 40 of rectangular section, with a pointed front end 41 and having at its rear end a tab 42 serving as a support and driving abutment. The tab 42 also serves for disassembling the box to facilitate the extraction of the tongue.
Les figure SA, 5B de présentation analogue facilitent la comparaison de l'assemblage de l'invention (figure 5A) à l'assemblage connu à rainure et languette bâtarde (figure 5B). Cette comparaison met en. évidence les caractéristiques essentielles de l'invention : - les rainures de verrouillage 16, 26, formant le canal recevant la languette de verrouillage 40, Figures SA, 5B of similar presentation facilitate the comparison of the assembly of the invention (Figure 5A) to the known assembly groove and bastard tongue (Figure 5B). This comparison puts in. the essential characteristics of the invention: the locking grooves 16, 26 forming the channel receiving the locking tongue 40,
- les surfaces d'appui 15, 25 dont l'une (15) est avancée (A) et l'autre (25) est en retrait (R),  the bearing surfaces 15, 25 of which one (15) is advanced (A) and the other (25) is recessed (R),
Dans le cas de l'assemblage à rainure et languette bâtarde connu des panneaux 100, 200, l'un des panneaux (100) a une languette bâtarde 1 1 1 longue et l'autre 200 a une rainure 221 profonde puisque le côté intérieur 200a est continu sans retrait et que le chant du panneau 100 n'est pas avancé sur la partie subsistant sous la languette bâtarde 1 1 1.  In the case of the known bastard and tongue joint assembly of the panels 100, 200, one of the panels (100) has a long bastard tongue 1 1 1 and the other 200 has a deep groove 221 since the inner side 200a is continuous without shrinkage and that the edge of the panel 100 is not advanced on the part remaining under the bastard tongue 1 1 1.
Cette comparaison met en évidence dans l'assemblage de l'invention la forme du logement 21 du second panneau 20 qui ne se limite pas à la seule ramure d'assemblage 21 mais comporte une partie en retrait R devant la surface d'appui intérieure 25. Cette partie en retrait R est reportée sur la languette bâtarde 1 1 qui est plus courte du fait de l'avancée A de sa surface d'appui de chant 15. La partie en retrait R et la partie avancée A sont mises en évidence par des traits en pointillé.  This comparison shows in the assembly of the invention the shape of the housing 21 of the second panel 20 which is not limited to the single assembly groove 21 but has a recessed portion R in front of the inner bearing surface 25 This recessed part R is transferred to the bastard tongue 1 1 which is shorter because of the advance A of its abutment surface 15. The recessed part R and the advanced part A are highlighted by dotted lines.
La figure 5C montre l'assemblage à plat, joint, utilisant des accessoires d'assemblage tels que des vis, des chevilles des tourillons, des excentrique, tous ces accessoires sont schématisés ici par une vis 240 réunissant les panneaux 130, 230. Cet assemblage est complexe à préparer et nécessite les accessoires énoncés ci-dessus.  FIG. 5C shows the assembly flat, jointed, using assembly accessories such as screws, dowel pins, eccentric, all these accessories are schematized here by a screw 240 joining the panels 130, 230. This assembly is complex to prepare and requires the accessories listed above.
La figure 6 montre un premier mode de réalisation d'un caisson parallélépipédique 300 composé de deux parois latérales 20A, 20B d'une paroi inférieure 10A et d'une paroi supérieure 10B et d'un fond 50. Ces parois sont constituées par des panneaux assemblés par leurs côtés par un assemblage selon l'invention. La vue isométrique de la figure 6A montre la face avant. Les détails de l'assemblage décrits dans leur généralité à l'aide des figures 1 à 5, apparaissent aux figures 6B, 6C, 6D qui montrent des détails de certaines parties de paroi et de l'assemblage sachant que les assemblages des quatre coins du caisson sont réalisés de la même manière.  FIG. 6 shows a first embodiment of a parallelepiped box 300 composed of two side walls 20A, 20B of a bottom wall 10A and an upper wall 10B and a bottom 50. These walls are constituted by panels assembled by their sides by an assembly according to the invention. The isometric view of Figure 6A shows the front face. The details of the assembly described in their generality with the aid of FIGS. 1 to 5, appear in FIGS. 6B, 6C, 6D which show details of certain parts of the wall and of the assembly, knowing that the assemblies of the four corners of the caisson are made in the same way.
La disposition générale des parois latérales 20A, 20B et de la paroi inférieure 10A et de la paroi supérieure 10B, correspond aux principes généraux de la construction d'un meuble ou d'un caisson : le fond 10A et le dessus 10B ne rejoignent pas le dessous et le dessus des parois latérales 20A, 20B, mais viennent contre le côté intérieur de ces parois. De manière détaillée et pour une zone d'assemblage de deux parois la figure 6B montre la rainure d'assemblage 21 de la paroi 20B débouchant à l'avant et laissant apparaître la surface d'appui intérieure 25, The general arrangement of the side walls 20A, 20B and the bottom wall 10A and the upper wall 10B, corresponds to the general principles of the construction of a piece of furniture or a box: the bottom 10A and the top 10B do not join the below and above the side walls 20A, 20B, but come against the inner side of these walls. In a detailed manner and for an assembly zone of two walls, FIG. 6B shows the assembly groove 21 of the wall 20B opening at the front and revealing the internal bearing surface 25,
La figure 6C montre un détail d'un côté d'assemblage du panneau 10A constituant la paroi inférieure du caisson 300. Ce côté correspond à la languette bâtarde 1 1 dont les caractéristiques géométriques sont celles déjà décrites aux figures 1 à 5. Cette figure 6C montre aussi la rainure de verrouillage 16 réalisée à la base de la languette bâtarde 1 1. Cette rainure 16 se termine avant la face avant du panneau 10A. Elle ne débouche pas dans la face avant, mais uniquement dans la face arrière (non représentée dans cette figure).  FIG. 6C shows a detail of an assembly side of the panel 10A constituting the bottom wall of the box 300. This side corresponds to the bastard tongue 1 1 whose geometric characteristics are those already described in FIGS. 1 to 5. This FIG. 6C also shows the locking groove 16 formed at the base of the bastard tongue 1 1. This groove 16 terminates before the front face of the panel 10A. It does not open in the front face, but only in the rear face (not shown in this figure).
La figure 6D montre l'aspect de l'assemblage des deux panneaux 1QA, 20B au niveau du coin inférieur droit, ne montrant pas les deux rainures de verrouillage formant le canal de verrouillage n'apparaissant pas à la face avant du caisson.  FIG. 6D shows the appearance of the assembly of the two panels 1QA, 20B at the bottom right corner, not showing the two locking grooves forming the locking channel not appearing at the front face of the box.
La figure 7 est une vue de la face arrière du caisson 300 qui, dans cet exemple, comporte un fond 50 logé dans des rainures 51-54 réalisées près du bord arrière de chacun des quatre panneaux 10A,B, 20A,B.  Figure 7 is a view of the rear face of the box 300 which, in this example, has a bottom 50 housed in grooves 51-54 made near the rear edge of each of the four panels 10A, B, 20A, B.
La figure 7A est une vue éclatée des quatre panneaux 10A? B, 20A, B constituant le caisson 300 et du panneau de fond 50. Cette vue isométrique laisse apparaître la rainure 51 près du bord arrière du panneau inférieur LQA et la rainure 52 près du bord arrière du panneau latéral droit 20A. Figure 7A is an exploded view of the four panels 10A ? B, 20A, B constituting the box 300 and the bottom panel 50. This isometric view shows the groove 51 near the rear edge of the bottom panel LQA and the groove 52 near the rear edge of the right side panel 20A.
Les autres panneaux 10B, 20B ont des rainures 53, 54 dans la même position de façon à constituer une rainure périphérique qui reçoit le bord du panneau constituant le fond 50, par simple engagement par la forme.  The other panels 10B, 20B have grooves 53, 54 in the same position so as to form a peripheral groove which receives the edge of the panel constituting the bottom 50, by simple engagement by the form.
La figure 7B montre l'un des coins découpés 55 du panneau de fond 50 de manière à ce qu'une fois le fond engagé dans les rainures 51-54, le coin 55 ne déborde pas dans les rainures de verrouillage 16, 26 des panneaux assemblés et n'interdise la mise en place des languettes de verrouillage 40 dans les CH.-Q n.l 30 fermés par l'assemblage des coins.  Figure 7B shows one of the cut corners 55 of the bottom panel 50 so that once the bottom engaged in the grooves 51-54, the corner 55 does not protrude into the locking grooves 16, 26 of the panels assembled and prohibits the establishment of the locking tongues 40 in CH.-Q nl 30 closed by the assembly of the corners.
La vue de détail de la figure 7C montre la rainure 52 dans le panneau inférieur 10A rainure de verrouillage 16 le long du bord d'assemblage de ce panneau inférieur 10A.  The detail view of Fig. 7C shows the groove 52 in the lower panel 10A locking groove 16 along the joining edge of this bottom panel 10A.
La figure 7D est une vue du coin inférieur du panneau latéral droit 20A montrant la rainure 52 recevant le bord du panneau de fond 50, Cette rainure 52 ne coupe pas la surface d'appui intérieure 25 du bord du panneau latéral 20A. puisque la rainure 52 pour le bord du fond 50 est à la même profondeur que la rainure 26 recevant la languette de verrouillage 40 et que, comme cela apparaît à la figure 1 , la rainure de verrouil- lage a l'un de ses côtés dans le prolongement de la surface d'appui intérieure 25, du seul fait que la rainure de verrouillage est réalisée par fraisage, ce qui aboutit à cette disposition coplanaire, Figure 7D is a view of the lower corner of the right side panel 20A showing the groove 52 receiving the edge of the bottom panel 50, This groove 52 does not cut the inner bearing surface 25 of the edge of the side panel 20A. since the groove 52 for the edge of the bottom 50 is at the same depth as the groove 26 receiving the locking tab 40 and that, as shown in FIG. 1, the locking groove has one of its sides in the extension of the internal bearing surface 25, simply because the locking groove is made by milling, which results in this coplanar arrangement,
La figure 8 montre dans ses parties 8A-8C, différentes détails de la poursuite de l'assemblage et du verrouillage du caisson 300.  Figure 8 shows in its parts 8A-8C, various details of the further assembly and locking of the box 300.
Ainsi, la figure 8A montre la situation au niveau d'un coin inférieur du panneau latéral 20B, le panneau de fond 50 étant engagé dans sa rainure 51 et le coin découpé 55 laisse libre la rainure de verrouillage 16 à la base de la languette bâtarde 1 1 de ce côté du panneau inférieur 10A. La partie découpée 55 du panneau de fond 50 remonte au- dessus de la surface du panneau inférieur 10A pour ne pas couper la rainure de verrouillage 26 du second panneau 20B représenté à gauche.  Thus, FIG. 8A shows the situation at a lower corner of the side panel 20B, the bottom panel 50 being engaged in its groove 51 and the cut corner 55 leaves the locking groove 16 free at the base of the bastard tongue. 1 1 on this side of the bottom panel 10A. The cutout portion 55 of the bottom panel 50 rises above the surface of the bottom panel 10A so as not to cut the locking groove 26 of the second panel 20B shown to the left.
La figure 8B montre une vue arrière du caisson 300 dont le fond 50 a été mis dans les rainures 51-54 et les quatre panneaux 10A, B ; 20A, B assemblés par l'engagement de chaque languette bâtarde dans sa rainure respective. Cette figure indique également les languettes de verrouillage 40,  Figure 8B shows a rear view of the box 300 whose bottom 50 has been placed in the grooves 51-54 and the four panels 10A, B; 20A, B assembled by the engagement of each bastard tongue in its respective groove. This figure also indicates the locking tabs 40,
La figure 8C est une vue à échelle agrandie de cette languette de verrouillage 40 face au canal de verrouillage 30. La languette de verrouillage 40 est constituée par une lame d'une certaine épaisseur ter- minée côté arrière par une languette de préhension 42.  FIG. 8C is a view on an enlarged scale of this locking tab 40 facing the locking channel 30. The locking tab 40 is constituted by a blade of a certain thickness terminated at the rear by a gripping tab 42.
La figure 9 montre dans ses parties 9A-9D, une variante de caisson 400 qui diffère du caisson 300 dit. "à rainures" décrit aux figures 7 et 8 par sa feuillure 61-64 recevant le fond 70.  Figure 9 shows in its parts 9A-9D, a variant of box 400 which differs from the box 300 said. "with grooves" described in Figures 7 and 8 by its rabbet 61-64 receiving the bottom 70.
Selon la figure 9A, les quatre panneaux 10AA, 10BB ; 20AA, 20BB destinés à être assemblés, comportent un bord arrière formant une feuillure 61-64 pour recevoir le panneau de fond 70 dont les coins ne sont pas découpés à l'endroit des rainures de verrouillage 16, 26.  According to FIG. 9A, the four panels 10AA, 10BB; 20AA, 20BB for assembly, have a trailing edge 61-64 for receiving the bottom panel 70 whose corners are not cut at the location of the locking grooves 16, 26.
La figure 9B montre le détail, d'un coin arrière du panneau, inférieur 10AA avec la rainure de verrouillage 16 qui débouche à l'arrière au-dessus de la partie formant la feuillure 61 (un dépassement du bord inférieur du panneau). La figure 9C montre la forme inférieure du panneau latéral montrant la feuillure. Les autres coins des panneaux latéraux et des panneaux inférieurs et. supérieurs, ont une structure homologue. Figure 9B shows the detail of a rear corner of the panel, lower 10AA with the locking groove 16 which opens at the rear above the portion forming the rabbet 61 (an overshoot of the lower edge of the panel). Figure 9C shows the lower shape of the side panel showing the rebate. The other corners of the side panels and the bottom panels and. higher, have a homologous structure.
Lorsque les panneaux 10AA-20BB sont assemblés et verrouillés chaque fois par une languette de verrouillage 40, la feuillure 61- 64 reçoit le panneau de fond 70 qui est simplement placé dans la feuillure 61-64. Il est fixé à. l'aide d'agrafes ou de pointes 71 comme le montre la figure 9D.  When the panels 10AA-20BB are assembled and locked each time by a locking tab 40, the rebate 61-64 receives the bottom panel 70 which is simply placed in the rabbet 61-64. It is fixed at. using staples or spikes 71 as shown in Figure 9D.
Selon un mode de réalisation non représenté, l'une des rainures de verrouillage, par exemple la rainure de verrouillage 26 loge une languette de verrouillage qui ne dépasse pas de l'ouverture de la rainure et après la réunion des deux panneaux, la languette bâtarde 1 1 étant à fond dans le logement d'assemblage 21, il suffit de faire descendre la lemguette de verrouillage en la repoussant, dans la rainure de verrouillage 16 de l'autre panneau 10, de façon que la rainure constitue un verrou venant à la fois en saillie dans la rainure de verrouillage 16 tout en restant en saillie dans la rainure de verrouillage 26. De façon avantageuse, la languette de verrouillage est de préférence placée dans la rainure de verrouillage 26 qui est parallèle au plan du panneau 20 plutôt que dans la rainure de verrouillage 16 du panneau 10 car alors elle serait perpendiculaire au plan du panneau et une profondeur de rainure de verrouillage 16 trop importante affaiblirait la languette bâtarde 1 1 ; cela n'est pas le cas pour la rainure de verrouillage 26 qui peut avoir une profondeur beaucoup plus importante sans que cela ne fragilise le futur assemblage,  According to an embodiment not shown, one of the locking grooves, for example the locking groove 26 houses a locking tab which does not protrude from the opening of the groove and after the meeting of the two panels, the bastard tongue 1 1 being fully in the assembly housing 21, it suffices to lower the locking lemugette by pushing it, in the locking groove 16 of the other panel 10, so that the groove constitutes a lock coming to the protruding into the locking groove 16 while projecting into the locking groove 26. Advantageously, the locking tab is preferably placed in the locking groove 26 which is parallel to the plane of the panel 20 rather than in the the locking groove 16 of the panel 10 because then it would be perpendicular to the plane of the panel and a depth of lock groove 16 too large weaken the tab stick arde 1 1; this is not the case for the locking groove 26 which can have a much greater depth without this weakening the future assembly,
La figure 10 montre un autre mode de réalisation de la languette de verrouillage 40 pour l'assemblage de deux panneaux 10, 20 qui diffère de celui décrit ci-dessiis par l'organe de verrouillage 60 porté par l'extrémité arrière de la languette de verrouillage 40 qui, elle, reste identique. Selon ce mode de réalisation, le chant 10- 1, 20- 1 des deux panneaux 10, 20 est muni d'un décrochage formant une surface d'appui périphérique 10-2, 20-2 sur tous les panneaux 10, 20 au niveau de leur chant 10- 1, 20- 1 , en général le chant du côté arrière du caisson.  FIG. 10 shows another embodiment of the locking tongue 40 for the assembly of two panels 10, 20 which differs from that described above by the locking member 60 carried by the rear end of the tongue of FIG. lock 40 which remains identical. According to this embodiment, the edge 10-1, 20-1 of the two panels 10, 20 is provided with a stall forming a peripheral bearing surface 10-2, 20-2 on all the panels 10, 20 at the top. their singing 10-1, 20-1, usually singing the back side of the box.
Le caisson assemblé est représenté ici couché, en position horizontale.  The assembled box is shown here lying in horizontal position.
Dans l'exemple des figures 10, 1 1 A, 1 1B, les chants 10- 1, 20- 1 avec leur décrochement ont une forme est légèrement différente de ce qui apparaît dans les figures précédentes, par exemple dans la figure 8C. En effet, le décrochement est une partie fraisée qui borde le côté in té- rieur de chaque panneau de sorte que le canal 30 est coupé et débouche dans la surface d'appui 20-2 (ce débouché n'est pas représenté) et la languette bâtarde 1 1 est partiellement coupée par le décrochement formant la surface d'appui 20-2. La languette bâtarde 11 et la rainure d'assemblage 21 apparaissent sur le dessus de l'assemblage de la figure 10. In the example of FIGS. 10, 11A, 11B, the edges 10-1, 20-1 with their recess have a shape that is slightly different from that which appears in the preceding figures, for example in FIG. 8C. Indeed, the recess is a milled part which borders the internal side. each of the panels so that the channel 30 is cut and opens into the bearing surface 20-2 (this outlet is not shown) and the bastard tongue 11 is partially cut by the recess forming the bearing surface 20-2. The bastard tongue 11 and the assembly groove 21 appear on the top of the assembly of FIG. 10.
La description de ce mode de réalisation de la languette 40 avec son organe de verrouillage 60 faite pour un coin du caisson s'applique dans les mêmes conditions aux autres coins du caisson.  The description of this embodiment of the tongue 40 with its locking member 60 made for a corner of the box applies under the same conditions to the other corners of the box.
La languette de verrouillage 40, représentée engagée dans le canal 30 (non représenté) formé par l'assemblage des deux panneaux 10, 20, est munie à son extrémité supérieure correspondant au côté arrière de la languette, d'un organe d'accrochage qui vient se loger dans le dièdre formé par l'assemblage des deux panneaux et s'accrocher d'une part en s'appuyant sur le chant 10- 1 , 20- 1, c'est-à-dire ici la surface d'appui 10-2, 20-2 du décrochage et d'autre part, en venant s'engager par des lamelles d'accrochage 63- 1 dans la rainure 51, 52 (53, 54) périphérique réalisée dans les panneaux 10, 20 pour recevoir les bords du fond 50 du caisson.  The locking tab 40, shown engaged in the channel 30 (not shown) formed by the assembly of the two panels 10, 20, is provided at its upper end corresponding to the rear side of the tongue, a fastening member which is housed in the dihedron formed by the assembly of the two panels and hang on the one hand by leaning on the edge 10-1, 20-1, that is to say here the support surface 10-2, 20-2 of the stall and on the other hand, coming to engage by attachment slats 63-1 in the groove 51, 52 (53, 54) device made in the panels 10, 20 to receive the edges of the bottom 50 of the box.
De façon plus détaillée, l'organe de verrouillage 60 selon cet exemple de réalisation est constitué par une grande base 61 en forme d'équerre pour s'appuyer sur le chant 10-1, 20- 1 des panneaux 10, 20, ici sur les surfaces d'appui 10-2, 20-2 réalisées par les décrochements des chants 10- 1, 20-1. Cette grande base 61 est reliée à l'extrémité supérieure (selon l'orientation de cette figure) de la languette de verrouillage 40 ; cette extrémité supérieure est en général l'extrémité arrière de la languette puisque les chants 10- 1, 20- 1 correspondent au côté arrière du caisson par où on introduit les languettes de verrouillage 40.  In more detail, the locking member 60 according to this exemplary embodiment consists of a large base 61 in the form of a square to bear on the edge 10-1, 20-1 of the panels 10, 20, here on the bearing surfaces 10-2, 20-2 formed by the recesses of the edges 10-1, 20-1. This large base 61 is connected to the upper end (according to the orientation of this figure) of the locking tongue 40; this upper end is in general the rear end of the tongue since the edges 10-1, 20-1 correspond to the rear side of the box through which the locking tabs 40 are introduced.
La grande base 61 est munie d'une partie de liaison 62 en forme de dièdre venant s'appuyer contre les faces intérieures des panneaux 10, 20 sous les surfaces d'appui 10-2, 20-2. Cette partie de liaison en forme de dièdre 62 a une hauteur (h) correspondant sensiblement à la distance séparant le chant 10 - 1, 20-1 (ou ici la surface d'appui 10-2, 20-2) du bord de la rainure 51 , 52. L'extrémité de cette partie de liaison 62 porte une petite base 63 de forme triangulaire, barrant le fond du dièdre et se prolongeant au-delà de la partie de liaison 62 par deux lamelles d'accrochage 63- 1 en saillie venant dans la rainure 51 , 52 des panneaux 10, 20 au-dessus du fond 50.  The large base 61 is provided with a connecting portion 62 in the form of a dihedral coming to bear against the inner faces of the panels 10, 20 under the bearing surfaces 10-2, 20-2. This dihedral shaped connecting portion 62 has a height (h) corresponding substantially to the distance between the edge 10 - 1, 20-1 (or here the bearing surface 10-2, 20-2) of the edge of the groove 51, 52. The end of this connecting portion 62 carries a small base 63 of triangular shape, blocking the bottom of the dihedron and extending beyond the connecting portion 62 by two attachment slats 63-1. projection in the groove 51, 52 of the panels 10, 20 above the bottom 50.
La ramure périphérique 51-54 est en général suffisamment large pour que le fond 50 puisse s'y loger facilement et l'espace libre est alors occupé par les lamelles d'accrochage 63- 1 , 63-2 des deux côtés 62- 1 , 62-2 de la partie de liaison en forme de dièdre 62. La petite base 63 occupe ici l'intérieur du dièdre par une partie intérieure 63-3 munie d'une encoche 63-4 de façon à permettre le dégagement de l'organe de verrouil- lage 60 et l'extraction de la languette de verrouillage 40. The peripheral branch 51-54 is generally wide enough so that the bottom 50 can be easily accommodated therein and the free space is then occupied by the attachment slats 63-1, 63-2 on both sides 62-1, 62-2 of the dihedral-shaped connecting portion 62. The small base 63 here occupies the interior of the dihedron by a part 63-3 interior provided with a notch 63-4 so as to allow the release of the locking member 60 and the extraction of the locking tab 40.
Pour ce dêverrouillage, on utilise un outil schématisé par la ligne 64, représentant un outil faisant levier tel qu'un tournevis dont on introduit l'extrémité « inférieure » dans l'encoche 63-4 et que l'on appuie contre le bord de la grande base 61 pour effectuer un mouvement de levier en poussant selon la flèche F, pour extraire les lamelles d'accrochage 63- 1 de la rainure 51 , 52 et permettre ainsi de tirer l'organe de verrouillage 60 vers le haut avec la languette de verrouillage 40. Pour guider l'outil 64 et éviter qu'il ne glisse d'un côté ou de l'autre contre le grand côté de la grande base 61 , il est. prévu une découpe 61-3. Ce mouvement de déver- rouillage est un pivotement de la partie de liaison 62 autour de sa jonction avec la grande base 61 ou même un pivotement de l'ensemble de l'organe de verrouillage 60 autour de sa liaison avec l'extrémité de la langiiette de verrouillage 40 ou encore une déformation élastique de ces éléments en jouant dans les différents cas sur une certaine souplesse de la matière.  For this unlocking, a tool is shown schematically by the line 64, representing a lever-forming tool such as a screwdriver whose "lower" end is inserted into the notch 63-4 and which is pressed against the edge of the large base 61 to perform a lever movement by pushing the arrow F, to extract the attachment slats 63-1 of the groove 51, 52 and thus allow the locking member 60 to be pulled up with the tongue 40. To guide the tool 64 and prevent it from sliding on one side or the other against the long side of the large base 61, it is. provided a cut 61-3. This unlocking movement is a pivoting of the connecting portion 62 around its junction with the large base 61 or even a pivoting of the whole of the locking member 60 around its connection with the end of the tongue. locking 40 or elastic deformation of these elements playing in different cases on a certain flexibility of the material.
Comme représenté à la figure 10, l'organe de verrouillage 60 se compose d'une grande base 61 en équerre dont le côté 61-1 est relié à la languette de verrouillage 40 alors que l'autre côté 61-2 est libre. De même, la partie de liaison en forme de dièdre 62 est constituée de deux parois 62- 1, 62-2 mais selon une variante non représentée, l'organe de verrouillage pourrait se limiter à la seule paroi 62- 1 de la partie de liaison en forme de dièdre reliée à la grande base 61, elle-même limitée pratiquement à son côté 61- 1. Il en serait de même de la petite base 63 limitée à son seul côté avec la lamelle 63- 1 homologue au côté 61- 1 de la grande base 61 , Dans ce cas également, l'organe de verrouillage serait en appui sur le chant 20-1 du panneau 20 ou de sa surface d'appui 20-2 selon l'exemple représenté et sa lamelle 63- 1 viendrait dans la rainure 52 au- dessus du fond 50 pour bloquer la languette de verrouillage 40.  As shown in Figure 10, the locking member 60 is composed of a large base 61 at right angle whose side 61-1 is connected to the locking tab 40 while the other side 61-2 is free. Similarly, the dihedral-shaped connecting portion 62 consists of two walls 62-1, 62-2 but according to a variant not shown, the locking member could be limited to the single wall 62-1 of the part of dihedral-shaped connection connected to the large base 61, itself substantially limited to its side 61-1. It would be the same for the small base 63 limited to its only side with the plate 63- 1 homologous to the side 61- 1 of the large base 61, In this case also, the locking member would bear against the edge 20-1 of the panel 20 or its bearing surface 20-2 according to the example shown and its plate 63-1 would come into the groove 52 above the bottom 50 to lock the locking tongue 40.
De façon avantageuse, pour caler l'organe de verrouillage 60, les côtés 61- 1, 61-2 de la grande base 61 dépassent de la partie de liaison 62 d'une longueur sensiblement égale à la largeur (i) des surfaces d'appui 10-2, 20-2. La mise en place de la languette de verrouillage 40 avec son organe de verrouillage 60 est montrée par deux étapes aux figures 1 1 A, 1 1B. Advantageously, to wedge the locking member 60, the sides 61-1, 61-2 of the large base 61 protrude from the connecting portion 62 by a length substantially equal to the width (i) of the surfaces of support 10-2, 20-2. The establishment of the locking tongue 40 with its locking member 60 is shown by two steps in Figures 1 1 A, 1 1B.
La figure 1 1A montre l'introduction de la languette de ver- rouillage 40 dans le canal 30, l'extrémité de la languette 40 étant encore à l'extérieur de l'assemblage des panneaux 10, 20. Puis en continuant d'enfoncer la languette 40, on écarte légèrement l'organe de verrouillage 60 et on le fait glisser par le bord de ses deux lamelles d'accrochage contre la surface intérieure des deux panneaux 10, 20 jusqu'à ce que les lamelles 63- 1, 63-2 arrivent devant la rainure 51 , 52 des deux panneaux 10, 20 au-dessus du fond 50 et puissent s'y engager. Dans cette position, le dessous des côtés 61- 1 , 61-2 de la grande base 61 qui dépassent des côtés 62-1 , 62-2 de l'organe de partie de liaison 62 est alors en appui sur les surfaces d'appui 10-2, 20-2. L'organe de verrouillage 60 constitue ainsi à la fois une cale pour le fond 50 et un moyen de verrouillage de la languette de verrouillage 40 pour que celle-ci ne puisse s'échapper vers l'arrière (côté des chants 10- 1 , 20- 1) sous l'effet des mouvements ou des vibrations auxquels le caisson pourrait être soumis.  FIG. 11A shows the introduction of the locking tongue 40 into the channel 30, the end of the tongue 40 being still outside the assembly of the panels 10, 20. Then continuing to drive the tab 40, the locking member 60 is slightly spaced apart and is slid by the edge of its two attachment strips against the inner surface of the two panels 10, 20 until the plates 63- 1, 63 -2 arrive in front of the groove 51, 52 of the two panels 10, 20 above the bottom 50 and can engage. In this position, the underside of the sides 61-1, 61-2 of the large base 61 protruding from the sides 62-1, 62-2 of the connecting portion member 62 is then resting on the bearing surfaces 10-2, 20-2. The locking member 60 thus constitutes both a wedge for the bottom 50 and a locking means of the locking tongue 40 so that it can not escape towards the rear (side of the edges 10-1, 20-1) under the effect of the movements or vibrations to which the box could be subjected.
La vue en coupe de la figure 12 met en évidence la partie de liaison 62 en forme de dièdre avec sa petite base 63 se prolongeant côté « extérieur » par les lamelles d'accrochage 63-1 , 63-2. Cette figure montre également la partie intérieure 63-3 avec l'encoche 63-4 ainsi que la languette de verrouillage 40, coupée par le plan I.  The sectional view of Figure 12 highlights the connecting portion 62 in the form of dihedral with its small base 63 extending on the "outer" side by the attachment slats 63-1, 63-2. This figure also shows the inner part 63-3 with the notch 63-4 and the locking tongue 40, cut by the plane I.
Le triangle tracé en trait interrompu est le contour de la grande base 61 qui n'apparaît pas dans cette vue en coupe de dessus.  The triangle drawn in broken line is the outline of the large base 61 which does not appear in this view in section from above.
La figure 13 est une vue en coupe de dessous selon le plan Si montrant la partie de liaison en forme de dièdre 62, coupée, de même que la languette de verrouillage 40. La grande base 61 avec ses deux côtés 61- 1, 61-2 apparaît ainsi que l'encoche 63-4.  FIG. 13 is a bottom sectional view along the plane Si showing the dihedral shaped connecting portion 62, cut, as well as the locking tongue 40. The large base 61 with its two sides 61-1, 61- 2 appears as well as the notch 63-4.
La figure 14 est une vue de dessus de l'assemblage montrant par transparence les différents éléments déjà décrits ci-dessus. L'encoche 63-4 apparaît du fait de la découpe 61-3 réalisée dans la grande base 61.  Figure 14 is a top view of the assembly showing by transparency the various elements already described above. The notch 63-4 appears due to the cut 61-3 made in the large base 61.
La figure 15 est une vue de dessous de la languette de ver- rouillage 40 avec son organe de verrouillage 60.  FIG. 15 is a bottom view of the locking tab 40 with its locking member 60.
La figure 16 est une variante de la languette de verrouillage 40 et de son organe de verrouillage 60 dans lequel la petite base 63 ne comporte pas de partie intérieure 63-3 ni d'encoche 63-4, les autres parties identiques aux précédentes portent les mêmes références. FIG. 16 is a variant of the locking tongue 40 and its locking member 60 in which the small base 63 does not has no inner portion 63-3 nor notch 63-4, the other parts identical to the previous ones have the same references.
Selon la figure 17, la languette 40A est une languette fractionnable de manière à pouvoir facilement adapter sa, longueur à la profondeur du caisson à partir d'une languette de longueur uniforme.  According to Figure 17, the tongue 40A is a splittable tongue so as to easily adapt its length to the depth of the box from a tongue of uniform length.
Cette languette est subdivisée par des réductions locales de section 41- 1, 41-2 (41-i) réparties régulièrement ou irrégulièrement sur la longueur de base de la languette 40A et définissant des segments (42- 1 , 42-2...42-i) de longueur Li égale ou différente pour la meilleure adaptation à la profondeur d'un caisson.  This tongue is subdivided by local reductions section 41- 1, 41-2 (41-i) distributed regularly or irregularly over the base length of the tongue 40A and defining segments (42-1, 42-2 ... 42-i) of length Li equal to or different for the best adaptation to the depth of a box.
Les segments ainsi délimités ont une longueur Li et les réductions de section 41-i sont constituées par des encoches réalisées par moulage de la languette 40A.  The segments thus delimited have a length Li and section reductions 41-i consist of notches made by molding the tongue 40A.
Les réductions de section 41-i ont des surfaces arrondies A1B 1 (AiBi) de façon à éviter tout accrochage dans le canal formé par l'assemblage des deux panneaux du caisson recevant la languette. Section reductions 41-i have rounded surfaces A1B 1 (AiBi) so as to avoid any attachment in the channel formed by the assembly of the two panels of the box receiving the tongue.
