Description

La présente invention concerne un système pour l'assemblage d'au moins deux pièces le long de leurs surfaces d'allure plane en regard, et est plus particulièrement destinée à s'appliquer dans le domaine du mobilier, pour relier deux plateaux horizontaux formant plan de travail à un unique piétement support.The present invention relates to a system for assembling at least two parts along their facing planar surfaces, and is more particularly intended to be applied in the field of furniture, to connect two horizontal plates forming a plane work table with a single support base.

Ce dernier doit bien entendu pouvoir également être fixé à un unique plan de travail, dans des conditions équivalentes.The latter must of course also be able to be fixed to a single work plan, under equivalent conditions.

On connaît déjà des dispositifs permettant d'assurer partiellement ces fonctions. Ainsi, le brevet européen EP 0 458 042 porte sur un système de verrouillage rotatif disposé sous des plateaux de table, et coopérant avec des tenons situés sur la partie supérieure de pieds supports. Chaque pied peut être soit entièrement situé sous un unique plateau, soit partagé entre deux plateaux contigus, dont les chants en regard viennent alors en contact l'une de l'autre.Devices are already known which make it possible to partially perform these functions. Thus, European patent EP 0 458 042 relates to a rotary locking system arranged under table tops, and cooperating with tenons located on the upper part of support legs. Each leg can either be entirely located under a single plate, or shared between two adjoining plates, whose facing edges then come into contact with one another.

La plaque de blocage du pied est munie de boutonnières coopérant avec lesdits tenons, et pivote autour d'un axe vertical, ce qui implique qu'elle n'occupe nécessairement qu'une surface limitée. En effet, une plaque d'allure circulaire et comportant des moyens de blocage périphériques ayant vocation à s'appliquer en bordure du plateau d'une table doit être d'un diamètre raisonnable, afin de ne pas déborder, pour d'évidentes raisons économiques et techniques. Par conséquent, ce système ne peut s'appliquer que dans des régions d'angles, en coopération avec des pieds classiques à section de faible importance.The blocking plate of the foot is provided with buttonholes cooperating with said pins, and pivots about a vertical axis, which implies that it necessarily occupies only a limited area. In fact, a plate with a circular appearance and comprising peripheral blocking means intended to be applied at the edge of the table top must be of a reasonable diameter, so as not to overflow, for obvious economic reasons. and techniques. Consequently, this system can only be applied in corner regions, in cooperation with conventional feet of small cross section.

Un tel système implique au surplus le montage séquentiel d'un premier pied, puis du second, alors que les commandes de blocage de chacun des pieds sont d'un accès malaisé, puisqu'elles sont situées sous la surface inférieure de chaque plateau. Du point de vue montage, l'installation de pieds sous un unique plateau ou sous deux plateaux horizontaux accolés par leurs chants transversaux est équivalente.Such a system moreover involves the sequential mounting of a first leg, then of the second, while the locking commands of each of the legs are difficult to access, since they are located under the lower surface of each tray. From the mounting point of view, the installation of feet under a single plate or under two horizontal plates joined by their transverse edges is equivalent.

L'objet de la présente invention permet au contraire de réaliser en une seule opération la fixation d'un piétement supportant un côté d'un plateau ou deux côtés de deux plateaux accolés.The object of the present invention allows instead to achieve in a single operation the fixing of a base supporting one side of a plate or two sides of two adjoining plates.

En outre, le verrouillage simultané du piétement au plateau s'effectue très aisément, et est réalisable de l'extérieur du volume couvert par ledit plateau, en une seul manoeuvre de l'opérateur.In addition, the simultaneous locking of the base to the tray is very easy, and is achievable from outside the volume covered by said tray, in a single maneuver by the operator.

De même, le déverrouillage simultané de la totalité des points de fixation le long d'un ou de deux chants (dans les deux hypothèses précitées) est possible simplement en réalisant la manoeuvre contraire à la précédente.Similarly, the simultaneous unlocking of all the fixing points along one or two edges (in the two aforementioned cases) is possible simply by performing the maneuver contrary to the previous one.

L'objectif principal de l'invention est donc de simplifier à l'extrême l'assemblage et le désassemblage d'un piétement à un ou deux plateaux horizontaux.The main objective of the invention is therefore to simplify in the extreme the assembly and disassembly of a base with one or two horizontal plates.

A cet effet, d'une manière très générale, l'invention consiste en un système pour l'assemblage d'au moins deux pièces le long de leurs surfaces d'allure plane en regard, la première comportant au moins deux boutons perpendiculaires munis d'une rainure, chaque bouton pouvant se loger dans un orifice de la seconde pièce, à laquelle est associé un organe mobile parallèlement à elle, du côté opposé à la surface en regard de la première pièce, ledit organe pouvant se déplacer entre une position de fermeture verrouillant les deux pièces l'une contre l'autre, et une position d'ouverture permettant de les désolidariser, caractérisé en ce que les boutons perpendiculaires sont situés à distance l'un de l'autre, l'organe mobile agissant simultanément sur eux par coulissement le long de la seconde pièce, suivant un axe défini par la ligne rejoignant lesdits boutons.To this end, in a very general manner, the invention consists of a system for assembling at least two parts along their facing planar surfaces, the first comprising at least two perpendicular buttons provided with '' a groove, each button being able to be housed in an orifice of the second part, with which is associated a movable member parallel to it, on the side opposite the facing surface of the first piece, said member being able to move between a position of closure locking the two parts against each other, and an open position making it possible to separate them, characterized in that the perpendicular buttons are located at a distance from each other, the movable member acting simultaneously on them by sliding along the second part, along an axis defined by the line joining said buttons.

Les deux pièces visées ci-dessus sont bien entendu d'une part un plateau horizontal formant plan de travail, et d'autre part un piétement destiné à supporter ledit plateau.The two parts referred to above are of course on the one hand a horizontal plate forming a work surface, and on the other hand a base intended to support said plate.

L'avantage considérable procuré par l'invention réside dans l'utilisation combinée de boutons dépassant de la surface inférieure du plan de travail, et situés de préférence dans ses zones d'angle, et d'un moyen de verrouillage opérant par coulissement et coopérant simultanément avec tous lesdits boutons le long d'un chant.The considerable advantage provided by the invention resides in the combined use of buttons protruding from the lower surface of the work surface, and preferably located in its corner areas, and a locking means operating by sliding and cooperating simultaneously with all of said buttons along a song.

La forme de l'organe de verrouillage coulissant à donc fait l'objet d'une étude particulièrement approfondie, du fait de sa double coopération d'une part avec la pièce dans laquelle elle coulisse et d'autre part avec les boutons du plateau horizontal.The shape of the sliding locking member has therefore been the subject of a particularly in-depth study, due to its double cooperation on the one hand with the part in which it slides and on the other hand with the buttons of the horizontal plate. .

Cet organe mobile comporte un cadre d'allure allongée dont la forme est prévue pour coopérer avec la rainure des boutons en obturant partiellement les orifices de la seconde pièce en position fermée, ladite forme permettant de libérer la totalité de la surface desdits orifices lors du coulissement visant à obtenir la position d'ouverture.This movable member comprises an elongated frame whose shape is designed to cooperate with the groove of the buttons by partially closing the orifices of the second part in the closed position, said shape making it possible to free the entire surface of said orifices during sliding. aimed at obtaining the open position.

De préférence, l'organe mobile comporte un cadre élastique réalisé en fil métallique dessinant des sinuosités obturant une partie de la périphérie de la surface des orifices de la seconde pièce en position fermée.Preferably, the movable member comprises an elastic frame made of metal wire drawing sinuosities closing part of the periphery of the surface of the orifices of the second part in the closed position.

De plus, pour pouvoir être manipulable pratiquement de l'extérieur du volume couvert par le plateau horizontal, il comporte, à l'une de ses extrémités, un élément de préhension dépassant de la surface de la seconde pièce, et permettant la manipulation par coulissement entre la position fermée et la position ouverte.In addition, to be able to be manipulated practically from outside the volume covered by the horizontal plate, it comprises, at one of its ends, a gripping element projecting from the surface of the second part, and allowing manipulation by sliding. between the closed position and the open position.

Cet élément de préhension est conçu de sorte qu'il puisse être manoeuvré par simple traction ou pression exercée à l'aide d'un doigt de l'utilisateur, sans effort excessif, dans une zone située à proximité d'un chant du plateau horizontal formant plan de travail.This gripping element is designed so that it can be maneuvered by simple traction or pressure exerted with the finger of the user, without excessive effort, in an area located near a edge of the horizontal plate. forming work plan.

Cet organe coopère de façon étroite avec la seconde pièce, c'est à dire le piétement. En réalité, l'interaction mécanique a lieu dans la partie supérieure du piétement, qui est destinée à supporter le plateau horizontal, et que l'on nomme la semelle supérieure du piétement.This member cooperates closely with the second part, that is to say the base. In reality, the mechanical interaction takes place in the upper part of the base, which is intended to support the horizontal plate, and which is called the upper sole of the base.

Cette semelle est en fait un profilé comportant notamment une surface dans laquelle sont pratiqués les orifices destinés à loger les boutons de la première pièce, ainsi que des découpes, pliages et emboutissages formant notamment la glissière de l'organe mobile.This sole is in fact a profile comprising in particular a surface in which are formed the orifices intended to accommodate the buttons of the first part, as well as cutouts, folds and stampings forming in particular the slide of the movable member.

Située au sommet du piétement, ladite surface est plane et est configurée horizontalement de manière à supporter le plateau formant le plan de travail du bureau. C'est dans cette surface que sont par conséquent pratiqués les découpes, pliages et emboutissages formant la glissière, selon des techniques de fabrication bien connues, faciles à mettre en oeuvre et abaissant d'une manière importante les coûts de fabrication.Located at the top of the base, said surface is flat and is configured horizontally so as to support the tray forming the work surface of the office. It is therefore in this surface that the cutouts, bends and stampings forming the slide are made, according to well known manufacturing techniques, easy to implement and significantly lowering manufacturing costs.

De préférence, la seconde pièce et l'organe mobile sont symétriques suivant un plan médian qui est parallèle à l'axe de coulissement et perpendiculaire aux surfaces en regard, de part et d'autre duquel sont pratiqués notamment deux séries d'orifices destinés à loger des boutons de deux premières pièces homologues.Preferably, the second part and the movable member are symmetrical along a median plane which is parallel to the sliding axis and perpendicular to the facing surfaces, on either side of which are made in particular two series of orifices intended to accommodate buttons from the first two homologous parts.

Lorsqu'un piétement n'est associé qu'à un unique plateau, les boutons de ce dernier coopèrent avec un seul jeu d'orifices, ceux qui sont le plus proche du chant latéral dudit plateau, de manière que le piétement soit compris dans le volume couvert par celui-ci. La semelle du piétement est alors voisine du chant latéral dudit plateau.When a base is only associated with a single plate, the buttons of the latter cooperate with a single set of orifices, those which are closest to the lateral edge of said plate, so that the base is included in the volume covered by it. The base of the base is then close to the lateral edge of said plate.

En utilisation avec deux plateaux accolés, le plan de séparation ou plan de contact est confondu avec le plan de symétrie.In use with two adjoining plates, the separation plane or contact plane is coincident with the plane of symmetry.

Avec un ou deux plateaux, l'assemblage est extrêmement simple, puisqu'il suffit de loger les tétons ou boutons placés sous le plateau dans les orifices correspondants du piétement. Ceci se fait naturellement en utilisant la gravitation, le centrage étant facilité par le fait que les boutons sont solidaires de la pièce du haut, dont on utilise par conséquent le poids au cours du montage.With one or two trays, assembly is extremely simple, since it suffices to house the pins or buttons placed under the tray in the corresponding holes in the base. This is done naturally by using gravitation, centering being facilitated by the fact that the buttons are integral with the top part, the weight of which is therefore used during assembly.

Comme on l'a évoqué, les moyens de mises en oeuvre et de fabrication de l'invention sont peu onéreux, et le montage des éléments de bureaux est extrêmement rapide, rendant l'invention très attrayante sur le plan économique.As mentioned, the means of implementing and manufacturing the invention are inexpensive, and the assembly of office elements is extremely rapid, making the invention very attractive from an economic point of view.

Dans la suite, on va procéder à une description détaillée du système, notamment en référence aux figures annexées, pour lesquelles :

  • La figure 1 est une vue perspective d'un piétement surmonté d'une semelle selon l'invention ;
  • La figure 2 est une vue de côté montrant un piétement et un plateau horizontal en cours d'assemblage ;
  • La figure 3 montre le même ensemble monté ;
  • La figure 4 représente un bureau monté en perspective ;
  • La figure 5 est une vue en perspective d'un organe de verrouillage mobile, et
  • La figure 6 est une vue de dessus d'une semelle.
In the following, we will proceed to a detailed description of the system, in particular with reference to the appended figures, for which:
  • Figure 1 is a perspective view of a base surmounted by a sole according to the invention;
  • Figure 2 is a side view showing a base and a horizontal plate during assembly;
  • Figure 3 shows the same assembly mounted;
  • Figure 4 shows a desk mounted in perspective;
  • FIG. 5 is a perspective view of a movable locking member, and
  • Figure 6 is a top view of a sole.

Les différentes figures représentent une configuration préférentielle de l'invention, appliquée à des ensembles de mobilier de bureaux, et plus spécifiquement à l'assemblage de piétements avec un ou plusieurs plateaux horizontaux formant plans de travail.The various figures represent a preferred configuration of the invention, applied to sets of office furniture, and more specifically to the assembly of legs with one or more horizontal plates forming work plans.

Dans une telle hypothèse, la partie du piétement p représenté en figure 1 qui est directement concernée par l'invention est la semelle 1, coopérant avec un organe mobile de verrouillage 2 permettant de bloquer un plateau horizontal comme on l'expliquera en détail ci-après. Celui-ci est figuré en cours de montage.In such a case, the part of the base p shown in FIG. 1 which is directly concerned by the invention is the sole 1, cooperating with a movable locking member 2 making it possible to block a horizontal plate as will be explained in detail below. after. This is shown during assembly.

La surface supérieure de la semelle 1 comporte des orifices, pliages et emboutissages dont les fonctions sont différenciées, et seront également clarifiées dans la suite.The upper surface of the sole 1 has holes, bends and stampings whose functions are differentiated, and will also be clarified below.

A titre principal, les orifices 3a à 3d et 4a à 4d sont destinés à assurer la liaison avec des tétons ou boutons 5 positionnés sur la surface inférieure du plateau horizontal 6 (voir figure 2). Selon une configuration préférentielle, chaque plateau ne comporte au voisinage d'un chant que deux boutons espacés de telle sorte qu'ils coopèrent avec des orifices référencés par une lettre identique (3a, 4a ; 3b, 4b ; ...). Dans ce cas, il peut donc y avoir un réglage de position entre deux positions distinctes.Mainly, the orifices 3a to 3d and 4a to 4d are intended to provide the connection with pins or buttons 5 positioned on the lower surface of the horizontal plate 6 (see FIG. 2). According to a preferred configuration, each plate has in the vicinity of a song only two buttons spaced so that they cooperate with orifices referenced by an identical letter (3a, 4a; 3b, 4b; ...). In this case, there can therefore be a position adjustment between two distinct positions.

Bien entendu, rien n'empêche de placer lesdits boutons de manière différente, notamment si le plateau est particulièrement large ou lourd, ou même d'ajouter des boutons supplémentaires.Of course, nothing prevents placing said buttons differently, especially if the tray is particularly large or heavy, or even to add additional buttons.

L'organe mobile 2 coulisse dans la semelle, sous la surface supérieure sur laquelle repose le plateau horizontal 6, et est réalisé sous forme filaire par une tige métallique pliée de telle sorte qu'elle puisse remplir la fonction qui lui est dévolue. Celle-ci consiste à bloquer les boutons 5 lorsque le plateau horizontal 6 repose sur la semelle 1, et que lesdits boutons 5 sont par conséquent insérés dans les orifices précités.The movable member 2 slides in the sole, under the upper surface on which the horizontal plate 6 rests, and is produced in wire form by a bent metal rod so that it can fulfill the function assigned to it. This consists in blocking the buttons 5 when the horizontal plate 6 rests on the sole 1, and when said buttons 5 are consequently inserted into the aforementioned holes.

L'organe mobile peut être déplacé entre une position de blocage et une position de déblocage. La position de blocage est obtenue lorsque l'organe 2 est en butée au fond de la semelle 1, car les sinuosités 7a à 7d et 8a à 8d (voir figure 5) sont alors au niveau des orifices 3a à 3d et 4a à 4d, qu'ils obstruent partiellement, coopèrant ainsi avec les rainures 10 des boutons 5 lorsque ceux-ci sont insérés.The movable member can be moved between a locking position and an unlocking position. The locking position is obtained when the member 2 is in abutment at the bottom of the sole 1, because the sinuosities 7a to 7d and 8a to 8d (see FIG. 5) are then at the orifices 3a to 3d and 4a to 4d, that they partially obstruct, thus cooperating with the grooves 10 of the buttons 5 when these are inserted.

Le déblocage est obtenu en tirant sur l'organe mobile 2 à l'aide d'une extrémité recourbée 9 faisant office d'élément de préhension ou de manoeuvre. La course entre la position de blocage et la position de déblocage est d'environ 15 mm. Ledit organe mobile 2 est réalisé d'une manière simple et peu onéreuse à l'aide d'une tige métallique pliée et déformée pour aboutir à la configuration de la figure 5.The release is obtained by pulling on the movable member 2 using a curved end 9 acting as a gripping element or maneuver. The travel between the locking position and the unlocking position is approximately 15 mm. Said movable member 2 is produced in a simple and inexpensive manner using a bent and deformed metal rod to result in the configuration of FIG. 5.

Les figures 2 et 3 montrent les positions relatives des différents éléments du système lorsque l'opération de montage est en cours, puis terminée. L'organe mobile de verrouillage est en position sortie en figure 2, et en butée à l'intérieur de la semelle 1 en figure 3, dans laquelle le plateau 6 horizontal est verrouillé au piétement p.Figures 2 and 3 show the relative positions of the various elements of the system when the mounting operation is in progress, then completed. The movable locking member is in the extended position in FIG. 2, and in abutment inside the sole 1 in FIG. 3, in which the horizontal plate 6 is locked to the base p.

La figure 4 complète la figure 3 en montrant en perspective les élément du bureau en position fixée. Les deux piétements p supportent le plateau horizontal 6, qui ne peut leur être désolidarisé puisque les boutons 5, au nombre de quatre dans cette configuration particulière, coopèrent avec les organes mobiles 2 en butée dans les semelles 1. L'élément de manoeuvre 9 dudit organe coulissant 2 est situé à proximité du chant longitudinal du plateau 6, aisément accessible à l'utilisateur, mais couvert par ledit plateau 6 en position fermée.Figure 4 completes Figure 3 showing in perspective the elements of the desk in the fixed position. The two legs p support the horizontal plate 6, which cannot be separated from them since the buttons 5, four in number in this particular configuration, cooperate with the movable members 2 abutting in the soles 1. The operating element 9 of said sliding member 2 is located near the longitudinal edge of the plate 6, easily accessible to the user, but covered by said plate 6 in the closed position.

La glissière permettant le coulissement de l'organe mobile 2 est réalisée par simples découpages, pliages et emboutissages de diverses formes dans la surface supérieure de la semelle 1. Ceux-ci apparaissent notamment en figure 6.The slide allowing the movable member 2 to slide is produced by simple cutting, bending and stamping of various shapes in the upper surface of the sole 1. These appear in particular in FIG. 6.

Outre les orifices destinés à loger les boutons 5 des plateaux supérieurs 6, référencés 3a à 3d et 4a à 4d, les semelles comportent des fentes 11a à 11d obtenues par découpage de deux lignes transversalement à la semelle, dans la partie centrale de celle-ci, puis par emboutissage de la zone située entre les deux lignes, qui descend sous le niveau de la surface supérieure de la semelle et ménage entre elles un espace de guidage pour l'organe mobile 2. Ce guidage est préférentiellement un guidage destiné à soutenir l'élément coulissant 2.In addition to the orifices intended to accommodate the buttons 5 of the upper plates 6, referenced 3a to 3d and 4a to 4d, the soles have slots 11a to 11d obtained by cutting two lines transversely to the sole, in the central part of the latter. , then by stamping the zone located between the two lines, which descends below the level of the upper surface of the sole and provides between them a guide space for the movable member 2. This guide is preferably a guide intended to support the sliding element 2.

Un guidage central est assuré par des fentes en forme de U 12a à 12c découpées dans la surface supérieure, les pièces délimitées par ces fentes étant ensuite repliées à 90°. La pièce métallique repliée ainsi créée s'insère entre les deux branches de la tige pliée formant l'organe de coulissement 9.Central guidance is provided by U-shaped slots 12a to 12c cut in the upper surface, the parts delimited by these slots are then folded back at 90 °. The folded metal part thus created is inserted between the two branches of the folded rod forming the sliding member 9.

Un guidage additionnel provient des fenêtres 13a et 13b également découpées sur trois faces puis repliées à 90° et qui comportent également une fente centrée analogue aux fentes précitées, c'est à dire opérant un guidage central.Additional guidance comes from windows 13a and 13b also cut on three sides then folded at 90 ° and which also have a centered slot similar to the aforementioned slots, ie operating a central guide.

Certains des orifices formés dans la semelle 1 peuvent additionnellement servir à loger l'extrémité d'un cavalier (non représenté) dont l'autre extrémité se loge dans un orifice homologue d'une semelle 1 identique, en vue de les solidariser l'une à l'autre.Some of the orifices formed in the sole 1 can additionally serve to accommodate the end of a jumper (not shown), the other end of which is housed in a homologous orifice of an identical sole 1, with a view to securing them one to the other.

Enfin, la surface supérieure de la semelle 1 comporte des tétons 14a, 14b et 14c dépassant légèrement et de surface supérieure plane, formant des zones d'appui disposées symétriquement par rapport à un axe longitudinal.Finally, the upper surface of the sole 1 comprises studs 14a, 14b and 14c projecting slightly and of planar upper surface, forming support zones arranged symmetrically with respect to a longitudinal axis.
