Description

La présente invention concerne une table pliante du type comprenant un plateau, deux piètements montés pivotants sur une face du plateau et des moyens de fixation des piètements au plateau lorsque la table est en position montée.The present invention relates to a folding table of the type comprising a tray, two legs pivotally mounted on one face of the tray and means for fixing the legs to the tray when the table is in the mounted position.

D'une manière générale, il existe de nombreux modèles de tables pliantes dont les structures varient au niveau des systèmes d'articulation entre piètements et plateau en fonction notamment de la forme des piètements, et au niveau des moyens de fixation en fonction notamment des dimensions de la table, en prenant également en compte les matériaux utilisés, la destination de la table et des facteurs économiques pour arriver à un rapport qualité/prix acceptable.In general, there are many models of folding tables, the structures of which vary at the level of the articulation systems between the legs and the top, depending in particular on the shape of the legs, and at the level of the fixing means, depending in particular on the dimensions. of the table, also taking into account the materials used, the destination of the table and economic factors to arrive at an acceptable quality / price ratio.

De telles tables présentent le plus souvent une stabilité et une rigidité très moyennes, c'est-à-dire qu'elles ne sont pas aptes à supporter des charges trop pesantes.Such tables most often have very average stability and rigidity, that is to say that they are not able to support too heavy loads.

Le but de l'invention est d'arriver à une structure de table pliante de conception entièrement nouvelle et qui permette de pallier notamment les inconvénients précités, tout en étant facile à monter et en ne faisant intervenir que des éléments constitutifs simples et en nombre limité, en particulier au niveau des articulations et des moyens de fixation entre piètements et plateau.The object of the invention is to arrive at a folding table structure of an entirely new design and which makes it possible in particular to overcome the aforementioned drawbacks, while being easy to assemble and using only simple constituent elements and in limited number , in particular at the level of the joints and the means of fixing between legs and top.

A cet effet, l'invention propse une table du type précité et qui se caractérise en ce que chaque piètement comprend au moins deux montants parallèles reliés l'un à l'autre par un premier élément de liaison qui supporte une partie des moyens de fixation dont l'autre partie est supportée par le plateau, et par un second élément de liaison articulé de façon pivotante au plateau.To this end, the invention provides a table of the aforementioned type and which is characterized in that each base comprises at least two parallel uprights connected one to the other by a first connecting element which supports part of the fixing means, the other part of which is supported by the plate, and by a second connecting element pivotally articulated to the plate.

Selon une autre disposition de l'invention, les moyens de fixation associés à chaque piètement comprennent un seul dispositif constitue par exemple par une tige filetée supportée par le premier élément de liaison et par un trou taraudé prévu dans le plateau ou dans un élément intermédiaire solidaire du plateau et dans lequel se visse la tige filetée pour assurer la solidarisation entre le piètement et le plateau.According to another arrangement of the invention, the fixing means associated with each base comprise a single device constituted for example by a threaded rod supported by the first connecting element and by a tapped hole provided in the tray or in an integral intermediate element of the tray and into which the threaded rod is screwed to secure the connection between the base and the tray.

Selon une autre disposition de l'invention conformément à un mode de réalisation particulier, les deux éléments de liaison forment un cadre rigide sur lequel vient en appui le plateau et tel que les deux montants d'au moins un piètement, en position montée de la table, se retrouvent à l'extérieur du plateau.According to another arrangement of the invention in accordance with a particular embodiment, the two connecting elements form a rigid frame on which the plate comes to bear and such that the two uprights of at least one base, in the mounted position of the table, are found outside the tray.

Selon une autre disposition de l'invention, les deux montants d'un piètement qui se retrouvent alors à l'extérieur du plateau en position montée de la table, sont des tubes creux dans l'un au moins desquels peut être engagée l'extrémité du pied de support d'un équipement auxiliaire tel une tablette.According to another arrangement of the invention, the two uprights of a base which are then found outside of the table in the mounted position of the table, are hollow tubes in at least one of which can be engaged the end the support leg of auxiliary equipment such as a tablet.

La table 1 conforme a l'invention comprend un plateau 2 et deux piètements 3 articulés à la face de dessous du plateau 2.Table 1 in accordance with the invention comprises a plate 2 and two legs 3 articulated on the underside of the plate 2.

Selon un premier mode de réalisation représenté aux figures 1 à 4, chaque piètement 3 comprend deux montants 4 tels deux éléments tubulaires parallèles formant pieds à une extrémité et qui, vers l'autre extrémité, sont réunis par un premier élément de liaison tel une barre transversale rigide 5. Chaque piètement 3 est articulé de façon pivotante au plateau 2 au moyen d'un second élément de liaison tel un tirant 6 relié aux montants 4. Plus précisément, le tirant 6 se présente sous la forme d'une tige métallique légèrement élastiquement déformable, en forme de U avec une partie centrale 6a et deux parties latérales ou ailes 6b dont les extrémités libres sont repliées sensiblement à 90° vers l'extérieur pour former des pions de liaison 6c.According to a first embodiment shown in Figures 1 to 4, each base 3 includes two uprights 4 such as two parallel tubular elements forming feet at one end and which, towards the other end, are joined by a first connecting element such as a bar rigid transverse 5. Each base 3 is pivotally articulated to the plate 2 by means of a second connecting element such as a tie rod 6 connected to the uprights 4. More specifically, the tie rod 6 is in the form of a slightly metallic rod elastically deformable, U-shaped with a central part 6a and two lateral parts or wings 6b whose free ends are folded substantially at 90 ° outwards to form connecting pins 6c.

Le tirant 6 n'est pas fixé de manière rigide aux montants 4. Après rapprochement des parties latérales 6b par déformation élastique et relâchement de celles-ci, les pions de liaison 6c sont engagés positivement dans deux trous 8 en vis-à-vis prévus dans les montants 4 tout en permettant à ceux-ci de pivoter par rapport à l'axe formé par les deux pions 6c axialement alignés. La partie centrale 6a du tirant 6 vient en appui contre la face de dessous du plateau 2 parallèlement à la barre 5 et est maintenue par deux charnières 9 pour relier de façon pivotante chaque piètement 3 au plateau 2.The tie rod 6 is not rigidly fixed to the uprights 4. After the lateral parts 6b have been brought together by elastic deformation and loosening thereof, the connecting pins 6c are positively engaged in two opposite holes 8 provided in the uprights 4 while allowing them to pivot relative to the axis formed by the two pins 6c axially aligned. The central part 6a of the tie rod 6 comes to bear against the underside of the plate 2 parallel to the bar 5 and is held by two hinges 9 to pivotally connect each base 3 to the plate 2.

Ainsi, comme les deux montants 4 peuvent pivoter autour des pions de liaison 6c et que le tirant 6 peut pivoter au moyen des charnières 9, les montants 4 peuvent grâce à ces deux articulations prendre soit une position à 90° par rapport au plateau 2 (position dépliée montrée a la figure 3), soit une position sensiblement parallèle au plateau 2 (position rabattue montrée à la figure 4).Thus, as the two uprights 4 can pivot around the connecting pins 6c and the tie rod 6 can pivot by means of the hinges 9, the uprights 4 can, thanks to these two articulations, take either a position at 90 ° relative to the plate 2 ( unfolded position shown in Figure 3), or a position substantially parallel to the plate 2 (folded position shown in Figure 4).

Il est important de noter que dans ce premier mode de réalisation, comme cela est visible aux figures 3 et 4, les charnières 9 sont fixées sur la face de dessous du plateau 2 en une position telle que la distance entre la partie centrale 6a du tirant 6 et le côté adjacent 2a du plateau 2 parallèle à ladite partie centrale 6a soit supérieure à la longueur des ailes 6b du tirant 6, de manière à ce que les extrémités libres des montants 4 opposées à celles formant les pieds viennent au contact du plateau 2 en position montée de la table 1 avant d'être maintenus dans cette position par des moyens de fixation 10 décrits ci-après.It is important to note that in this first embodiment, as can be seen in FIGS. 3 and 4, the hinges 9 are fixed on the underside of the plate 2 in a position such that the distance between the central part 6a of the tie rod 6 and the adjacent side 2a of the plate 2 parallel to said central part 6a is greater than the length of the wings 6b of the tie rod 6, so that the free ends of the uprights 4 opposite to those forming the feet come into contact with the plate 2 in the mounted position of the table 1 before being held in this position by fixing means 10 described below.

Les moyens de fixation entre chaque piètement 3 et le plateau 2 sont constitués par un seul dispositif 10 qui, dans l'exemple considéré ici, est une tige filetée 11a terminée à une extrémité par un bouton b de commande en rotation, et un trou taraudé 11b destiné à recevoir la tige filetée 11a. Cette tige 11a est montée au travers de la barre 5, sensiblement au milieu de celle-ci, et le trou taraudé 11b est prévu sur la face de dessous du plateau 2. Bien entendu, la longueur de la tige filetée 11a est supérieure à la distance séparant la barre 5 du plateau 2, lorsque chaque piètement 3 est en position dépliée.The fixing means between each base 3 and the plate 2 are constituted by a single device 10 which, in the example considered here, is a threaded rod 11a terminated at one end by a button b for controlling rotation, and a tapped hole 11b intended to receive the threaded rod 11a. This rod 11a is mounted through the bar 5, substantially in the middle of the latter, and the tapped hole 11b is provided on the underside of the tray 2. Of course, the length of the threaded rod 11a is greater than the distance separating the bar 5 from the tray 2, when each base 3 is in the unfolded position.

D'une manière préférentielle, il est prévu deux plaques 20 fixées à la face de dessous du plateau 2 pour servir d'interface entre les piètements 3 et le plateau 2, respectivement. Dans ce cas, chaque trou 11 comme représenté à la figure 2 est réalisé dans l'épaisseur de la plaque 20 associée. Chaque plaque 20 présente, en regard des deux montants 4 du piètement associé 3, deux portions cylindriques en saillie 21 d'un diamètre légèrement inférieur à celui des montants 4 pour s'emboîter dans ceux-ci et assurer une meilleure stabilité de la table 1 en position montée.Preferably, two plates 20 are provided fixed to the underside of the plate 2 to serve as an interface between the legs 3 and the plate 2, respectively. In this case, each hole 11 as shown in Figure 2 is made in the thickness of the associated plate 20. Each plate 20 has, opposite the two uprights 4 of the associated base 3, two projecting cylindrical portions 21 with a diameter slightly less than that of the uprights 4 to fit into them and ensure better stability of the table 1 in the mounted position.

Selon un second mode de réalisation représenté aux figures 5 à 7, chaque piètement 3a, 3b est formé par deux montants 4 tels que deux éléments tubulaires parallèles formant pieds à une extrémité et qui, à l'autre extrémité, sont réunis par un premier élément de liaison tel une barre transversale rigide 50. Chaque piètement 3a,3b est monté pivotant au plateau 2 au moyen d'un second élément de liaison tel une barre 60 en forme de U dont les deux extrémités libres des deux parties latérales ou ailes 60b sont reliées aux montants 4, de manière à ce que les barres 50,60 soient au contact du plateau 2 lorsque la table 1 est en position montée.According to a second embodiment shown in Figures 5 to 7, each base 3a, 3b is formed by two uprights 4 such that two parallel tubular elements forming feet at one end and which, at the other end, are joined by a first element of connection such as a rigid transverse bar 50. Each base 3a, 3b is pivotally mounted on the plate 2 by means of a second connecting element such as a U-shaped bar 60 whose two free ends of the two lateral parts or wings 60b are connected to the uprights 4, so that the bars 50.60 are in contact with the plate 2 when the table 1 is in the assembled position.

La partie centrale 60a de la barre 60 en appui contre le dessous du plateau 2 est maintenue par deux charnières 9 permettant au piètement 3a,3b associé de pivoter par rapport au plateau 2.The central part 60a of the bar 60 bearing against the underside of the plate 2 is held by two hinges 9 allowing the base 3a, 3b associated to pivot relative to the plate 2.

Dans ce second mode de réalisation, en considérant le piètement 3a (figures 5 et 7), les charnières 9 sont fixées sur la face de dessous du plateau 2 en une position telle que la distance de la partie centrale 60a de la barre 60 et le côté adjacent 2a du plateau 2 parallèle à ladite partie centrale 60a soit supérieure à la longueur des parties latérales 60b de la barre 60, de manière à ce que les extrémités libres des montants 4 opposées à celles formant les pieds viennent au contact du plateau 2 en position montée de la table 1.In this second embodiment, considering the base 3a (Figures 5 and 7), the hinges 9 are fixed on the underside of the plate 2 in a position such that the distance from the central part 60a of the bar 60 and the adjacent side 2a of tray 2 parallel to said central part 60a is greater than the length of the lateral parts 60b of the bar 60, so that the free ends of the uprights 4 opposite to those forming the feet come into contact with the plate 2 in the mounted position of the table 1 .

En considérant maintenant le piètement 3b (figures 5 et 6), les charnières 9 sont fixées sur la face de dessous du plateau 2 en une position telle que la longueur des parties latérales 60b de la barre 60 soit supérieure à la distance séparant les charnières 9 du côté adjacent 2a du plateau 2 parallèle à la partie centrale 60a de la barre 60, et que la distance séparant cette partie centrale 60a et la barre 50 soit inférieure à la distance précitée. Dans ces conditions, lorsque le piètement 3b est en position dépliée, les montants 4 se retrouvent à l'extérieur du plateau 2, alors que les barres 50 et 60 sont en contact avec le plateau 2 pour assurer la stabilité et la rigidité de la table 1.Now considering the base 3b (FIGS. 5 and 6), the hinges 9 are fixed on the underside of the plate 2 in a position such that the length of the lateral parts 60b of the bar 60 is greater than the distance separating the hinges 9 on the adjacent side 2a of the plate 2 parallel to the central part 60a of the bar 60, and that the distance separating this central part 60a and the bar 50 is less than the aforementioned distance. Under these conditions, when the base 3b is in the unfolded position, the uprights 4 are found outside the plate 2, while the bars 50 and 60 are in contact with the plate 2 to ensure the stability and rigidity of the table 1.

Les moyens de fixation 10 sont constitués comme dans le premier mode de réalisation par un seul dispositif 10 tel une tige filetée 10a, avec un bouton de commande en rotation 10b, qui est supportée par la barre 50 et qui coopère avec un trou taraudé 11b prévu dans la face de dessous du plateau 2 ou dans une plaque intermédiaire 20′ fixée au plateau 2.The fixing means 10 are constituted as in the first embodiment by a single device 10 such as a threaded rod 10a, with a rotary control button 10b, which is supported by the bar 50 and which cooperates with a tapped hole 11b provided in the underside of the plate 2 or in an intermediate plate 20 ′ fixed to the plate 2.

Comme schématiquement représenté à la figure 7, la position extérieure du piètement 3b par rapport au plateau 2 permet d'associer à la table un équipement auxiliaire tel qu'une tablette T qui est par exemple supportée par un montant tubulaire 4′ formant pied qui peut s'emboîter partiellement dans l'un des montants 4 du piètement 3b. Cette tablette T est par exemple une tablette de téléphone, lorsque la table sert de bureau.As schematically represented in FIG. 7, the external position of the base 3b relative to the plate 2 makes it possible to associate with the table an auxiliary equipment such as a shelf T which is for example supported by a tubular upright 4 ′ forming a foot which can partially fit into one of the uprights 4 of the base 3b. This tablet T is for example a telephone tablet, when the table serves as an office.

Le dispositif de fixation 10 utilisé dans les deux modes de réalisation décrits précédemment peut être remplacé par tout dispositif équivalent tel que celui illustré à la figure 8.The fixing device 10 used in the two embodiments described above can be replaced by any equivalent device such as that illustrated in Figure 8.

Dans ce cas, chaque dispositif de fixation 10 est du type à encliquetage automatique avec un pion 12b élastiquement rétractable qui coopère avec un orifice 12a. Dans l'exemple considéré, le pion 12b fait en partie saillie d'un boîtier 70 fixé a la face de dessous du plateau 2. Ce boîtier 70 renferme un ressort 71 qui permet au pion 12b de s'escamoter à l'intérieur du boîtier 70. L'orifice 12a est prévu dans le premier élément de liaison 5, 50 de chaque piétement 3, 3a et 3b.In this case, each fixing device 10 is of the automatic snap-on type with an elastically retractable pin 12b which cooperates with an orifice 12a. In the example considered, the pin 12b projects in part from a housing 70 fixed to the underside of the plate 2. This housing 70 contains a spring 71 which allows the pin 12b to retract inside the housing 70. The orifice 12a is provided in the first connecting element 5, 50 of each base 3, 3a and 3b.

Lors de l'opération de montage de la table, l'élément de liaison 5, 50 de chaque piètement 3 à la fin du mouvement pivotant de ce dernier, vient au contact du pion 12b associé et l'oblige à s'escamoter temporairement à l'intérieur du boîtier 70. Dès que l'orifice 12a de l'élément de liaison 5, 50 est en regard du pion 12b, celui-ci fait à nouveau saillie du boîtier 70 pour s'engager dans l'orifice 12a et assurer ainsi la fixation entre le piètement 3 et le plateau 2. Pour désolidariser le piétement 3, il suffit de prévoir un orifice 72 dans l'élément de liaison 5, 50 qui soit opposé à l'orifice 12a pour dégager le pion 12b au moyen d'un outil pointu engagé dans cet orifice 72.During the table mounting operation, the connecting element 5, 50 of each base 3 at the end of the latter's pivoting movement, comes into contact with the associated pin 12b and forces it to retract temporarily to inside the housing 70. As soon as the orifice 12a of the connecting element 5, 50 faces the pin 12b, the latter protrudes again from the housing 70 to engage in the orifice 12a and ensure thus the fixing between the base 3 and the plate 2. To separate the base 3, it suffices to provide an orifice 72 in the connecting element 5, 50 which is opposite to the orifice 12a to release the pin 12b by means of 'a pointed tool engaged in this orifice 72.

Bien évidemment, les deux modes de réalisation décrits précédemment ne sont pas limitatifs de l'invention, et des dispositions équivalentes peuvent être facilement envisagées par l'homme de métier sans sortir du cadre de l'invention. En particulier, chaque élément de fixation 10 associé à chaque piètement 3,3a,3b peut être également constitué par une simple vis.Obviously, the two embodiments described above are not limitative of the invention, and equivalent arrangements can be easily envisaged by those skilled in the art without departing from the scope of the invention. In particular, each fixing element 10 associated with each base 3.3a, 3b can also be constituted by a simple screw.
