L'invention concerne un dispositif d'agrandissement d'une table comportant au moins 3 plateaux, il comporte des moyens pour déplacer les au moins 3 plateaux d'une position initiale où ils forment une surface continue vers une position où ils sont écartés ies uns par rapport aux autres réalisant ainsi un espace vide entre eux. Le dispositif comporte au moins une rallonge comprenant au moins un axe de pivotement et un élément d'extrémité apte à pivoter autour de cet axe. Le dispositif comprend également des moyens mécaniques pour déplacer en translation verticale ou des moyens mécaniques pour déplacer en rotation la rallonge d'une position de rangement où elle est placée en dessous d'un plan contenant les plateaux 1 à une position où elle est alignée avec les plateaux 1 et vient ainsi remplir ledit espace vide de manière à agrandir uniformément la table.The invention relates to a device for enlarging a table comprising at least 3 trays, it comprises means for moving the at least 3 trays from an initial position where they form a continuous surface towards a position where they are separated one by one. compared to the others thus realizing an empty space between them. The device comprises at least one extension comprising at least one pivot axis and an end element pivotable about this axis. The device also comprises mechanical means for moving in vertical translation or mechanical means for rotating the extension of a storage position where it is placed below a plane containing the trays 1 at a position where it is aligned with trays 1 and thus fills said empty space so as to enlarge the table uniformly.
Selon l'invention, la table comprend une ossature comportant pour chacun des plateaux un support 2 destiné à recevoir tes moyens pour déplacer les plateaux 1 , des traverses de jonction 3 reliant chacune deux supports successifs entre eux et une ceinture 4. Les supports 2 sont munis chacun d'un carré 37 pouvant recevoir différents modèles de pieds et de ceintures. L'écartement entre Ses deux supports successifs permet de constituer un espace de fonctionnement pour la rallonge. Les moyens pour déplacer !es plateaux 1 en translation longitudinale sont selon l'invention, pour tous les modes de réalisation de l'invention, des glissières 31 montées chacune au dessus des supports. Ces glissières peuvent être des glissières à queue d'aronde. La figure 1 représente une vue de dessus d'une table ronde en position agrandie selon un premier mode de réalisation de l'invention. La table est constituée de quatre quarts plateaux 1 , comportant une seule rallonge d'un seul tenant ayant une forme de croix 5, et quatre éléments d'extrémité 6 qui sont attachés aux extrémités des bras de Ia rallonge en forme de croix. Les quatre éléments sont des demies rallonges, identiques aux quatre bras de la rallonge ayant une forme de croix 5. La rallonge est fixée sur deux longerons 7. Chaque longeron est articulé au moyen d'une paire de vérins à ressort 8, situés en opposition, de part et d'autre du bras de la rallonge.According to the invention, the table comprises a frame comprising for each of the trays a support 2 intended to receive your means for moving the trays 1, junction crosspieces 3 each connecting two successive supports between them and a belt 4. The supports 2 are each provided with a square 37 which can accommodate different models of feet and belts. The spacing between its two successive supports provides an operating space for the extension. The means for moving the trays 1 in longitudinal translation are according to the invention, for all the embodiments of the invention, slides 31 mounted each above the supports. These slides can be dovetailed slides. Figure 1 shows a top view of a round table in an enlarged position according to a first embodiment of the invention. The table is consisting of four quarters trays 1, having a single integral extension having a cross-shaped 5, and four end members 6 which are attached to the ends of the arms of the cross-shaped extension. The four elements are half extensions, identical to the four arms of the extension having a cross shape 5. The extension is fixed on two longitudinal members 7. Each beam is articulated by means of a pair of spring cylinders 8, located in opposition , on both sides of the extension arm.
L'ossature de Ia table du dispositif selon le premier mode de réalisation de l'invention comporte une ceinture 4, quatre supports triangulaires 2 pouvant recevoir différents modèles de pieds et de ceintures, quatre traverses de jonction 3, chacune des traverses relie deux supports successifs. Dans un autre mode de réalisation de l'invention, plusieurs traverses de jonction peuvent relier deux supports successifs, contribuant ainsi à renforcer ia structure de la table. L'ajustement angulaire des quatre quarts plateaux 1 à la fermeture de ceux-ci, c'est-à-dire lorsqu'ils sont à la position où ils forment une surface continue s'effectue sur la moitié de Ia longueur, grâce à la rallonge centrale en forme de croix 5.The frame of the table of the device according to the first embodiment of the invention comprises a belt 4, four triangular supports 2 can accommodate different models of feet and belts, four cross members 3, each of the ties connects two successive supports . In another embodiment of the invention, several cross ties can connect two successive supports, thereby helping to strengthen the structure of the table. The angular adjustment of the four quarter plates 1 at the closing thereof, that is to say when they are in the position where they form a continuous surface takes place on half the length, thanks to the central extension in the shape of a cross 5.
La figure 2 représente une vue de dessus en coupe partieϋe l'ossature d'un quart de la table avec un élément d'extrémité 6 fermé sur la rallonge, et un deuxième élément d'extrémité 6 ouvert, posé sur la ceinture 4. Les éléments sont reliés par des charnières invisibles 24 aux extrémités des bras de la rallonge en forme de croix 5. Ces charnières constituent un axe de pivotement pour les éléments d'extrémité pivotants 6. Lorsque la rallonge en forme de croix 5 est en position rangée, c'est-à- dire en dessous du plan des plateaux de la table, elle est maintenue en position horizontale par les deux axes 9, 10, l'ensemble étant posé sur les traverses de jonctions 3. Les traverses reliant entre deux supports triangulaires 2 sont fixées sous les supports, la longueur de l'écartement entre les deux supports permet d'obtenir un espace de fonctionnement entre la rallonge et le support, cet espace permettant le passage du corps du vérin 8 qui effectue des mouvements de rotation.FIG. 2 represents a sectional top view partly of the framework of a quarter of the table with an end element 6 closed on the extension, and a second open end element 6 placed on the belt 4. The elements are connected by invisible hinges 24 to the ends of the arms of the cross-shaped extension 5. These hinges constitute a pivot axis for the pivoting end elements 6. When the cross-shaped extension 5 is in the stowed position, that is to say below the plane of the trays of the table, it is maintained in a horizontal position by the two axes 9, 10, the assembly being placed on the crossings of junctions 3. The ties connecting between two triangular supports 2 are fixed under the supports, the length of the spacing between the two supports makes it possible to obtain an operating space between the extension and support, this space allowing the passage of the body of the cylinder 8 which performs rotational movements.
La figure 3 représente une vue en coupe d'un des bras de la rallonge en forme de croix 5 en position haute fixé sur un des deux longerons 7 avec l'élément d'extrémité 6 fermée sur la rallonge en forme de croix 5 en couvrant totalement le bras de la croix. Le vérin à ressort 8 est maintenu par les deux axes 9 et 10, le premier 9 étant fixé sur le longeron à travers d'une lumière réalisée dans le corps du vérin et le deuxième 10 fixé sur le support triangulaire 2. Une cale inclinée réglable 11 fixée sur le support assure par sa position angulaire la fin de course de la rotation du vérin lors du placement en translation verticale de la rallonge. La présence de cette cale 11 permet d'obtenir la hauteur précise pour la planéité avec les quatre quarts plateaux 1.3 shows a sectional view of one of the arms of the cross-shaped extension 5 in the upper position fixed on one of the two longitudinal members 7 with the end element 6 closed on the cross-shaped extension 5 by covering totally the arm of the cross. The spring cylinder 8 is held by the two axes 9 and 10, the first 9 being fixed to the spar through a light made in the body of the cylinder and the second 10 fixed on the triangular support 2. An adjustable inclined wedge 11 fixed on the support ensures by its angular position the end of stroke of the rotation of the cylinder during the placement in vertical translation of the extension. The presence of this wedge 11 makes it possible to obtain the precise height for the flatness with the four quarter plates 1.
Le maintien en position haute et la planéité de la rallonge par rapport aux plateaux 1 de la table sont donc assurés par le vérin à ressort 8 et ia cale inclinée réglable 11 disposée sur le corps du vérin.The holding in high position and the flatness of the extension relative to the trays 1 of the table are thus provided by the spring cylinder 8 and the inclined adjustable wedge 11 disposed on the body of the cylinder.
Lors de la mise en place de l'agrandissement, une levée de la rallonge est effectuée alternativement des deux côtés comportant les vérins à ressort. La prise en main des deux côtés de la rallonge 5 avec l'élément d'extrémité 6 fermé sur la rallonge est facilitée par le passage laissé entre l'arc de cercle de la ceinture 4 et le bord du bras de la rallonge 5. Les deux longerons 7 portant la rallonge effectuent un mouvement en translation verticale sur 6 cm au moyen des vérins à ressort 8 qui effectuent un mouvement de rotation dans le sens trigonométrique. Pour avoir uniquement un mouvement en translation vertical, pendant le mouvement de rotation du vérin, l'axe 9 fixé sur le longeron 7 vient appuyer l'extrémité du ressort 25 situé dans la lumière réalisé dans le corps du vérin 8. Cette compression du ressort 25 permet de compenser le déplacement longitudinal du longeron selon un axe longitudinal porté par le longeron. La levée du longeron 7 s'arrête lorsque Ia cafle inclinée 11 vient en butée contre la rallonge, indiquant ainsi la fin de la course angulaire du vérin à ressort 8. Lorsque la rallonge en forme de croix 5 est en positon haute, pour finir l'agrandissement, chaque élément d'extrémité 6 effectue une rotation de 180° par rapport à l'axe de pivotement situé aux extrémités de chaque bras de la rallonge pour venir prendre appui sur la ceinture 4 de la table. Celle-ci apporte par son porte-à-faux l'avantage de conserver la planéité sur une éventuelle faiblesse du ressort 25 du vérin.When setting up the enlargement, an extension of the extension is performed alternately on both sides with the spring cylinders. The grip on both sides of the extension 5 with the end element 6 closed on the extension is facilitated by the passage left between the arc of the waistband 4 and the edge of the arm of the extension 5. The two longitudinal members 7 carrying the extension perform a movement in vertical translation over 6 cm by means of the spring cylinders 8 which perform a rotational movement in the trigonometric direction. To have only a vertical translational movement, during the rotational movement of the jack, the axis 9 fixed on the spar 7 comes to support the end of the spring 25 located in the bore formed in the body of the jack 8. This spring compression 25 makes it possible to compensate the longitudinal displacement of the spar along a longitudinal axis carried by the spar. The lifting of the spar 7 stops when the inclined cafe 11 abuts against the extension, thus indicating the end of the angular stroke of the spring cylinder 8. When the cross-shaped extension 5 is in the high position, to finish the enlargement, each end element 6 rotates 180 ° relative to the pivot axis located at the ends of each arm of the extension to come take support on the belt 4 of the table. This brings by its overhang the advantage of keeping the flatness on a possible weakness of the spring 25 of the cylinder.
La figure 1 présente la vue de dessus de la table ronde agrandie, avec la rallonge 5 et les éléments d'extrémités 6 déployés et alignés avec les plateaux 1. Pour consolider l'ensemble, des crochets de fermeture 26 attachent de part et d'autre chaque élément d'extrémité 6 aux plateaux correspondant.FIG. 1 shows the top view of the enlarged round table, with the extension 5 and the end elements 6 deployed and aligned with the plates 1. To consolidate the assembly, closure hooks 26 attach to each other and to each other end member 6 to the corresponding trays.
Lors de la mise en place de la rallonge en position de rangement, chaque élément d'extrémité 6 est rabattu sur chaque bras de la rallonge 5 en forme de croix. Les deux côtés de la rallonge en forme de croix 5 comportant les vérins sont poussés alternativement vers le bas, pendant cette poussée le vérin effectue une rotation angulaire de 70° autour de l'axe 10, la rotation du vérin induit un déplacement en translation verticale vers le bas du longerons.When placing the extension in the storage position, each end element 6 is folded down on each arm of the extension 5 cross-shaped. The two sides of the cross-shaped extension 5 comprising the cylinders are pushed alternately downwards, during this thrust the cylinder performs an angular rotation of 70 ° around the axis 10, the rotation of the jack induces a displacement in vertical translation. down the spars.
Pendant ce mouvement de rotation du vérin accompagné du mouvement de translation vertical, l'axe 9 comprime le ressort 25 de 12 mm. L'ensemble de ces mouvements amène les longerons 7 par inclinaison en butée avec les traverses de jonction 3 fixées au dessous des supports 2During this movement of rotation of the cylinder accompanied by the vertical translation movement, the axis 9 compresses the spring 25 by 12 mm. All of these movements bring the longitudinal members 7 by inclination in abutment with the connecting rails 3 fixed below the supports 2
Selon une variante du premier mode de réalisation de l'invention, les moyens pour déplacer les rallonges en translation verticale peuvent être un bras télescopique qui permet de monter et descendre la rallonge en forme de croix 5.According to a variant of the first embodiment of the invention, the means for moving the extensions in vertical translation may be a telescopic arm which allows to move up and down the cross-shaped extension 5.
Ils peuvent être également des bras télescopiques montés chacun sur des supports correspondant, et portant la rallonge pour la faire monter et descendre.They can also be telescopic arms each mounted on corresponding supports, and carrying the extension to make it up and down.

Le clip de maintien 36 est enlevé permettant à l'élément d'extrémité d'effectuer une rotation de 180° par rapport à î'axe de pivotement constitué par des charnières invisibles 24 et de venir prendre appui sur la ceinture 4 entre deux plateaux de la table. La pîanéité avec les plateaux est assurée par la présence de joints 35 disposés sur les côtés de chaque élément d'extrémité et par l'attachement de chaque élément d'extrémité aux plateaux correspondant au moyen des crochets de fermeture 26.In a first step, the assembly constituting the extension and the end element rotates 180 ° relative to the axis of rotation fixed on the support 2 by means of the metal brackets 15 in order to remove the extension of the below the transom. The extension comes to bear on the cross member 3. The holding clip 36 is removed allowing the end member to rotate 180 ° relative to the pivot axis constituted by invisible hinges 24 and to come take support on the belt 4 between two trays of the table. The paneality with the trays is ensured by the presence of seals 35 arranged on the sides of each end element and the attachment of each end element to the corresponding plates by means of the closing hooks 26.
Pour finaliser l'agrandissement, l'espace vide central laissé vide par ies extrémités des rallonges présentant un côté sensiblement droit des quatre rallonges est rempli par le panneau 14 réversible et amovible.To finalize the enlargement, the central empty space left empty by the ends of the extensions having a substantially straight side of the four extensions is filled by the panel 14 reversible and removable.
Selon un troisième mode de réalisation de l'invention, le dispositif d'agrandissement comporte quatre rallonges 16, chacune des quatre rallonges comprend à une extrémité un élément d'extrémité pivotant 6 et à l'autre extrémité une pointe ayant un angle de 90° 34. Ce dispositif est représenté sur la figure 8 qui illustre une vue de dessus d'une table ronde en position d'agrandie comportant ce dispositif d'agrandissement.According to a third embodiment of the invention, the enlarging device comprises four extensions 16, each of the four extensions comprises at one end a pivoting end element 6 and at the other end a tip having an angle of 90 ° 34. This device is shown in Figure 8 which shows a top view of a round table in enlarged position with this enlarging device.
Les éléments d'extrémité 6 pivotant sont des demies rallonges articulées qui sont attachées chacun aux extrémités des rallonges à l'aide des charnières classiques 27. Avantageusement, les charnières classiques 27 sont fixées au dessous des rallonges et des éléments d'extrémité, permettant d'avoir une structure de base à l'état brut pour le dessus des quatre quart plateaux et des rallonges, laissant ainsi la possibilité de choisir le composant pour la finition du dessus. Notamment le composant pour la finition du dessus peut être du carrelage. Les éléments d'extrémité 6 viennent se rabattre et de s'ouvrir par rapport à !a rallonge par un mouvement de rotation de 180° au moyen d'un axe de pivotement qui est constitué par les charnières classiques 27.The pivoting end members 6 are articulated extension halves which are each attached to the ends of the extensions by means of the conventional hinges 27. Advantageously, the conventional hinges 27 are attached below the extensions and the end members, allowing the to have a raw basic structure for the top of the four quarter trays and extensions, thus leaving the possibility of choosing the component for finishing the top. In particular, the component for finishing the top may be tiling. The end members 6 are folded down and opened relative to the extension by a rotational movement of 180 ° by means of a pivot axis which is constituted by the conventional hinges 27.
Selon l'invention, l'ossature de ce dispositif est modifiée par l'apport d'un croisillon central 19, les extrémités de chaque bras du croisillon étant fixées sous les supports triangulaires 2. Le centre du croisillon est confondu avec le centre de la table. Les traverses de jonction 3 reliant chacune deux supports successifs 2 sont montées sous le support 2, réalisant ainsi un espace de fonctionnement pour les rallonges.According to the invention, the framework of this device is modified by the provision of a central spider 19, the ends of each arm of the spider being fixed under the triangular supports 2. The center of the spider is merged with the center of the table. The connecting crosspieces 3 each connecting two successive supports 2 are mounted under the support 2, thus providing an operating space for the extensions.
La figure 9 représente une vue de dessus en coupe d'un quart de Sa table de la figure 8. Elle illustre un des éléments d'extrémité ouvert en prenant appui sur la ceinture et un deuxième élément fermé. La figure 10 illustre l'une des quatre rallonges en position de rangement en dessous du plan de la table. En position de rangement, l'élément d'extrémité 6 se trouve replié sous la rallonge 16, et ils sont maintenus ensemble à l'aide d'un clip 23. L'ensemble est maintenu en position horizontale parallèle au plan de la table dune part par une paire de leviers 17 et d'autre part en contre poids en appui sur une élément de maintien 18 qui est une butée fixée sur le support 2.FIG. 9 represents a top view in section of a quarter of its table of FIG. 8. It illustrates one of the open end elements while resting on the belt and a second closed element. Figure 10 illustrates one of the four extensions in storage position below the plane of the table. In the storage position, the end element 6 is folded under the extension 16, and they are held together by means of a clip 23. The assembly is held in a horizontal position parallel to the plane of the table dune part by a pair of levers 17 and secondly against weight bearing on a holding element 18 which is a stop fixed on the support 2.
La paire de leviers 17 est disposée de part et d'autre de chaque rallonge, chaque levier étant monté d'une part en rotation sur ladite rallonge par un premier axe 29 fixé dans la rallonge et d'autre part en rotation sur le support correspondant par un deuxième axe 28 fixé dans le support.The pair of levers 17 is disposed on either side of each extension, each lever being mounted firstly in rotation on said extension by a first axis 29 fixed in the extension and secondly in rotation on the corresponding support by a second axis 28 fixed in the support.
L'angle de repos du levier 17 obtenue par une butée 33 permet d'avoir un jeu de fonctionnement pour la rotation de la rallonge entre la rallonge et la ceinture 4. La mise en place de Ia sortie de la rallonge est réalisée en deux temps, elle est illustrée sur les figures 11 et 12.The angle of repose of the lever 17 obtained by a stop 33 makes it possible to have an operating clearance for the rotation of the extension between the extension and the belt 4. The installation of the output of the extension is carried out in two stages it is illustrated in Figures 11 and 12.
Dans un premier temps, une prise en main est effectuée du côté des extrémités comportant les charnières classiques 27, l'ensemble est soulevé par un mouvement en rotation autour de l'axe 29, l'ensemble est amené par contre poids en position d'appui sur la traverse de jonction 3, avec l'extrémité de la rallonge comportant la pointe en appui sur la traverse telle qu'elle représentée sur la figure 11.At first, a grip is performed on the side of the ends comprising the conventional hinges 27, the assembly is lifted by a rotational movement about the axis 29, the assembly is brought against weight in the position of support on the connecting crossbar 3, with the end of the extension having the point bearing on the crosspiece as shown in Figure 11.
Dans un deuxième temps, après avoir enlevé la fixation du clip 23 qui maintient ensemble la rallonge 16 et l'élément d'extrémité 6, une prise en main facilitée par la position inclinée de l'ensemble est effectuée du côté de l'extrémité de l'élément d'extrémité pivotant 6 afin de le placer en appui sur la ceinture 4.In a second step, after removing the attachment of the clip 23 which holds together the extension 16 and the end member 6, a grip facilitated by the inclined position of the assembly is performed on the side of the end of the pivoting end element 6 in order to place it in abutment on the belt 4.
La figure 12 illustre la position de l'élément d'extrémité en appui sur la ceinture. Chaque élément d'extrémité comporte chacun une vis 21 , la vis étant fixée en dessous d'une des extrémité de l'élément. Chacune des vis est destinée à venir s'enclencher dans une fourchette 22 fixée sur la ceinture. Cet enclenchement est réalisé par une légère poussée horizontale de 2.5 cm sur l'élément. Les fourchettes permettent ainsi de fixer un axe de poussée, un centrage et assure une pianéité des éléments avec les plateaux. Elles évitent également un effet de basculement de la rallonge sous le poids de l'élément. Cette même poussée permet au levier 17 par sa position angulaire, d'effectuer une légère rotation autour de l'axe 28 d'un angle de 50° et d'effectuer une rotation de 135 ° autour de Taxe 29. La combinaison de la rotation des deux axes permet d'aligner la rallonge avec les plateaux 1.Figure 12 illustrates the position of the end member resting on the belt. Each end element each comprises a screw 21, the screw being fixed below one end of the element. Each of the screws is intended to snap into a fork 22 fixed on the belt. This engagement is achieved by a slight horizontal push of 2.5 cm on the element. The forks thus make it possible to fix an axis of thrust, a centering and ensures a pianety of the elements with the plates. They also avoid a tilting effect of the extension under the weight of the element. This same thrust allows the lever 17 by its angular position, to perform a slight rotation about the axis 28 by an angle of 50 ° and to rotate 135 ° around Tax 29. The combination of the rotation two axes allows to align the extension with the plates 1.
Selon l'invention, une cale 20 est fixée sous la pointe de chaque rallonge. Pendant l'alignement, cette cale vient en butée contre l'angle formé entre deux bras du croisiilon 19, permettant ainsi d'assurer l'alignement de la rallonge avec les plateaux.According to the invention, a shim 20 is fixed under the tip of each extension. During alignment, this wedge abuts against the angle formed between two arms of the crank 19, thus ensuring the alignment of the extension with the trays.
Avantageusement, l'élément d'extrémité 6 est réglable en hauteur en réalisant un logement 30 permettant un choix de composant et de son épaisseur pour la surface de finition du plateau.Advantageously, the end element 6 is adjustable in height by providing a housing 30 allowing a choice of component and its thickness for the finishing surface of the tray.
Selon ce troisième de réalisation de l'invention, la fabrication complète des tables peut être réalisée totalement ou partiellement avec des matières différentes.According to this third embodiment of the invention, the complete manufacture of the tables can be carried out totally or partially with different materials.
Selon l'invention, pour tous les modes de réalisation de l'invention, le déplacement en translation longitudinale des plateaux d'une position initiale où les plateaux forment une surface continue vers une position où ils sont écartés les uns par rapport aux autres réalisant un espace vide est accompli au moyen des glissières 31. Ces glissières qui peuvent être des glissières à queue d'aronde sont montées sur supports. According to the invention, for all the embodiments of the invention, the displacement in longitudinal translation of the trays of an initial position where the trays form a continuous surface towards a position where they are spaced apart from each other realizing a empty space is accomplished by means of the slides 31.
