Description

La présente invention concerne un nouveau mode de positionnement et de maintien en place d'un plan de travail horizontal sur un élément d'appui, et notamment du plateau d'un meuble de bureau sur le dessus d'un bloc dans lequel sont logés des tiroirs ou analogues, dans le cas où ce plateau et ce bloc constituent des éléments d'un système modulaire, tel que décrit par exemple dans le Brevet Européen N° 91440021.3 de la Déposante.The present invention relates to a new method of positioning and holding in place a horizontal work plan on a support element, and in particular the tray of an office furniture on top of a block in which are housed drawers or the like, in the case where this tray and this block constitute elements of a modular system, as described for example in European Patent No. 91440021.3 of the Applicant.

Dans un système de ce genre, il est usuel d'assurer le positionnement et le maintien en place d'un plateau sur son appui au moyen de couples téton/cuvette pratiqués respectivement dans le plateau et l'appui ou inversement, ou par des chevilles traversant complètement le plateau pour venir s'insérer dans un logement de l'appui.In a system of this kind, it is customary to ensure the positioning and the holding in place of a plate on its support by means of nipple / bowl pairs practiced respectively in the plate and the support or vice versa, or by pins completely crossing the plate to come and fit into a housing of the support.

Toutefois, l'un des avantages de ces systèmes étant la possibilité de retourner un plateau de forme angulaire, pour en inverser l'orientation et créer ainsi des formes illimitées de plans de travail, cette faculté de retournement implique que le plateau possède des moyens de positionnement et/ou de maintien en place sur ses deux faces, ce qui nuit à l'esthétique de l'ensemble puisque ceux de ces moyens qui ne sont pas utilisés demeurent visibles sur le dessus des plateaux.However, one of the advantages of these systems being the possibility of inverting an angular-shaped tray, in order to reverse the orientation and thus create unlimited forms of worktops, this faculty of inversion implies that the tray has means of positioning and / or holding in place on its two faces, which affects the aesthetics of the assembly since those of these means which are not used remain visible on the top of the plates.

L'invention vise un nouveau système assurant efficacement ce positionnement et ce maintien en place, et intervenant latéralement sur le champ du plateau, c'est à dire n'affectant pas ni l'une ni l'autre des faces du plan de travail qu'il constitue, quelle que soit son orientation.The invention relates to a new system effectively ensuring this positioning and this holding in place, and acting laterally on the field of the plate, ie not affecting either of the faces of the work surface that 'it constitutes, whatever its orientation.

A cet effet, dans la face supérieure du bloc d'appui, au voisinage d'au moins l'un de ses bords, est logée une pièce intermédiaire fixe comportant sur deux côtés opposés des rainures horizontales parallèles entre elles et à ladite face supérieure et perpendiculaires audit bord, une pièce intermédiaire mobile en forme de fourche horizontale venant s'insérer dans lesdites rainures et comportant un talon vertical dont la face avant vient s'insérer dans une échancrure de forme et dimension correspondantes pratiquée dans le champ dudit plateau, sa face arrière étant de niveau avec ledit champ.For this purpose, in the upper face of the support block, in the vicinity of at least one of its edges, is housed a fixed intermediate piece comprising on two opposite sides horizontal grooves parallel to each other and to said upper face and perpendicular to said edge, a movable intermediate piece in the form of a horizontal fork coming to be inserted in said grooves and comprising a vertical heel, the front face of which is inserted in a notch of corresponding shape and dimension practiced in the field of said plate, its face rear being level with said field.

De préférence, l'ensemble des deux pièces intermédiaires est rendu solidaire au moyen d'une vis traversant l'épaisseur de la fourche parallèlement aux rainures et vissée dans la pièce intermédiaire fixe. Selon un perfectionnement particulièrement utile, alors que le vissage de cette vis assure le blocage en place de l'ensemble et par suite du plateau sur le bloc d'appui, le système à vis est du type qui, par dévissage, avec maintien de la vis immobile en direction axiale par rapport à la pièce intermédiaire mobile, assure le déplacement vers l'arrière de cette pièce intermédiaire mobile, qui par ailleurs serait d'accès difficile en cas de démontage.Preferably, the assembly of the two intermediate parts is made integral by means of a screw passing through the thickness of the fork parallel to the grooves and screwed into the fixed intermediate part. According to a particularly useful improvement, while the screwing of this screw ensures the blocking in place of the assembly and consequently of the plate on the support block, the screw system is of the type which, by unscrewing, with maintenance of the screw immobile in axial direction relative to the movable intermediate piece, ensures the rearward movement of this movable intermediate piece, which would otherwise be difficult to access in the event of disassembly.

L'existence de la pièce intermédiaire fixe, d'une épaisseur de l'ordre de 10 à 15 mm a pour conséquence que le plateau est maintenu à une distance correspondante du dessus du bloc. Cet espacement contribue à l'esthétique du meuble, mais pour garantir la stabilité du plateau, il est prévu, selon l'invention, de disposer sur le dessus du bloc un certain nombre de cales en matière souple, de même hauteur que la pièce intermédiaire fixe.The existence of the fixed intermediate piece, with a thickness of the order of 10 to 15 mm, has the consequence that the plate is kept at a corresponding distance from the top of the block. This spacing contributes to the aesthetics of the furniture, but to guarantee the stability of the tray, it is provided, according to the invention, to have on the top of the block a number of shims made of flexible material, the same height as the intermediate piece fixed.

Pour assurer l'immobilité en rotation de la pièce intermédiaire fixe, et par suite le maintien en direction perpendiculaire au bord du plateau des rainures qu'elle comporte, il est prévu sous ladite pièce intermédiaire fixe un élément d'ancrage auxiliaire sur la face du bloc, par exemple un téton venant se loger dans ladite face.To ensure the immobility in rotation of the fixed intermediate piece, and consequently the maintenance in the direction perpendicular to the edge of the plate of the grooves which it comprises, there is provided under said fixed intermediate piece an auxiliary anchoring element on the face of the block, for example a stud coming to lodge in said face.

De même, pour prévenir une mise en place défectueuse du talon vertical dans l'échancrure du champ du plateau, un élément d'ancrage auxiliaire est prévu sur ledit talon, par exemple un téton venant se loger dans le fond de ladite échancrure.Likewise, to prevent faulty positioning of the vertical heel in the notch of the platform field, an auxiliary anchoring element is provided on said heel, for example a stud coming to be housed in the bottom of said notch.

Le système de positionnement et de maintien selon l'invention présente de nombreux avantages.The positioning and holding system according to the invention has many advantages.

En premier lieu, il ne comporte pratiquement aucun élément visible de l'extérieur, la seule pièce non dissimulée étant le talon de la pièce intermédiaire mobile venant se loger dans une échancrure du champ du plateau. Du fait que l'on ne peut voir de ce talon que la face arrière qui est à niveau avec ledit champ, et de préférence de même couleur, la ligne de ce champ apparaît pratiquement continue, sauf bien entendu, si, pour des raisons purement esthétiques, les couleurs des faces du plateau et du talon de la pièce intermédiaire mobile sont différentes.First, it has practically no element visible from the outside, the only non-concealed part being the heel of the movable intermediate part which is housed in a notch in the field of the plate. Because we can see from this heel only the rear face which is level with said field, and preferably of the same color, the line of this field appears practically continuous, except of course, if, for purely reasons aesthetic, the colors of the faces of the plate and the heel of the movable intermediate piece are different.

La surface du plateau ne comporte aucun élément du système, de sorte que, conformément à une caractéristique essentielle de l'invention, ce système permet d'utiliser un plateau indifféremment sur l'une ou l'autre de ses deux faces, par simple retournement. Cette réversibilité du plateau permet la création d'ensembles mobiliers très variés, comme il était déjà suggéré dans le EP-A-91440021.3 précité. Aucun autre système de positionnement et de maintien en place ne permet cette réversibilité sans affecter l'aspect des plateaux, puisque tous les systèmes connus font appel à des moyens affectant la surface des plateaux ou même leur perforation.The surface of the plate does not include any element of the system, so that, in accordance with an essential characteristic of the invention, this system makes it possible to use a plate either on one or the other of its two faces, by simple inversion . This reversibility of the tray allows the creation of very varied sets of furniture, as was already suggested in the aforementioned EP-A-91440021.3. No other positioning and holding system allows this reversibility without affecting the appearance of the plates, since all known systems use means affecting the surface of the plates or even their perforation.

Au surplus, le système selon l'invention est d'une extrême robustesse, ce qui est conforme aux normes internationales en vigueur.Furthermore, the system according to the invention is extremely robust, which complies with the international standards in force.

Enfin, il est d'une très grande simplicité, aussi bien pour sa mise en place que pour son démontage, ne faisant intervenir qu'une simple vis, d'ailleurs non visible de l'extérieur.Finally, it is very simple, both for its installation and for its disassembly, involving only a single screw, moreover not visible from the outside.

On va maintenant décrire l'invention en se référant au dessin annexé, sur lequel :

  • La figure 1 est une coupe verticale schématique du système selon l'invention, en place pour le maintien et le positionnement du plateau d'un ensemble de bureau sur un bloc d'appui.
  • La figure 2 est une vue de dessous suivant II-II de la figure 1.
  • Les figures 3a et 3b sont des vues en perspective de la pièce intermédiaire mobile en forme de fourche du système selon l'invention, respectivement par dessus et par dessous.
  • La figure 4 est une vue en perspective de la pièce intermédiaire fixe ou "sabot".
  • Enfin, la figure 5 illustre le mécanisme à vis permettant à la fois le blocage du système en place et l'extraction de la pièce intermédiaire mobile.
We will now describe the invention with reference to the accompanying drawing, in which:
  • Figure 1 is a schematic vertical section of the system according to the invention, in place for the maintenance and positioning of the tray of an office assembly on a support block.
  • Figure 2 is a bottom view along II-II of Figure 1.
  • Figures 3 a and 3 b are perspective views of the movable intermediate piece bifurcated system according to the invention, respectively from above and below.
  • Figure 4 is a perspective view of the fixed intermediate piece or "shoe".
  • Finally, FIG. 5 illustrates the screw mechanism allowing both the locking of the system in place and the extraction of the movable intermediate piece.

Le système selon l'invention est destiné au positionnement et au maintien en place du plateau P d'un meuble de bureau sur un bloc d'appui A.The system according to the invention is intended for positioning and holding in place the tray P of an office furniture on a support block A.

Ce système se compose d'une pièce intermédiaire fixe ou "sabot", désignée par la référence générale (1), et d'une pièce intermédiaire mobile, désignée par la référence générale (2), coopérant entre elles et avec le plateau P et le bloc A, en étant bloquées en position assemblée par un mécanisme à vis, désignée par la référence générale (3).This system consists of a fixed intermediate piece or "shoe", designated by the general reference (1), and a mobile intermediate piece, designated by the general reference (2), cooperating with each other and with the plate P and the block A, being locked in the assembled position by a screw mechanism, designated by the general reference (3).

En se référant plus spécialement à la figure 4, on voit que la pièce (1) est formée par une plaque de base (4), de préférence en métal moulé tel que du "ZAMAK", renforcé par des nervures (5), portant sur la face supérieure une plaque d'appui (6) également en "ZAMAK", et sur sa face inférieure deux tétons (7) et (8). La plaque d'appui (6) est solidaire de la plaque de base (4) par une zone de raccordement définissant deux rainures (9) et (10) parallèles entre elles et à l'axe XX' réunissant les axes des tétons (7) et (8), et qui est, comme on le voit sur la figure 2, perpendiculaire au bord B du plateau P. Le téton (7) a un diamètre sensiblement supérieur à celui du téton (8), et comporte un alésage intérieur (11), lisse et destiné à recevoir une vis autotaraudeuse.Referring more particularly to FIG. 4, it can be seen that the part (1) is formed by a base plate (4), preferably of molded metal such as "ZAMAK", reinforced by ribs (5), bearing on the upper face a support plate (6) also in "ZAMAK", and on its lower face two pins (7) and (8). The support plate (6) is integral with the base plate (4) by a connection zone defining two grooves (9) and (10) parallel to each other and to the axis XX 'joining the axes of the studs (7 ) and (8), and which is, as seen in FIG. 2, perpendicular to the edge B of the plate P. The stud (7) has a diameter substantially greater than that of the stud (8), and has an internal bore (11), smooth and intended to receive a self-tapping screw.

Dans la zone située au dessus dudit téton (7), la plaque de base (4) comporte une surépaisseur (12) dans laquelle est pratiqué un filetage horizontal (13) pour le mécanisme à vis, comme il sera décrit plus loin en détail.In the area above said stud (7), the base plate (4) has an extra thickness (12) in which a horizontal thread (13) is made for the screw mechanism, as will be described later in detail.

Comme on le voit en particulier sur la figure 1, le sabot (1) est mis en place sur la face supérieure F1 du bloc A, chaque téton (7) et (8) étant enfoncé dans un logement correspondant, une vis de maintien verticale (non représentée) étant vissée à travers la paroi du bloc A dans l'alésage (11). Le téton (8) sert à empêcher toute rotation éventuelle du sabot (1) autour du téton (7), ce qui affecterait la bonne orientation des rainures (9) et (10) qui doivent demeurer perpendiculaires au bord B du plateau P.As can be seen in particular in FIG. 1, the shoe (1) is placed on the upper face F1 of the block A, each stud (7) and (8) being inserted in a corresponding housing, a vertical retaining screw (not shown) being screwed through the wall of the block A in the bore (11). The stud (8) serves to prevent any possible rotation of the shoe (1) around the stud (7), which would affect the correct orientation of the grooves (9) and (10) which must remain perpendicular to the edge B of the plate P.

En se référant maintenant plus spécialement aux figures 3a et 3b, on voit que la pièce intermédiaire mobile (2), réalisée également en un métal tel que le "ZAMAK", se compose d'une fourche désignée par la référence générale (20) et d'un talon désigné par la référence générale (21) et perpendiculaire au plan de la fourche (20).Referring now more particularly to FIGS. 3 a and 3 b , it can be seen that the movable intermediate piece (2), also made of a metal such as the "ZAMAK", consists of a fork designated by the general reference (20) and a heel designated by the general reference (21) and perpendicular to the plane of the fork (20).

Comme le montre en particulier la figure 3b, la fourche (20) se compose d'un corps arrière (22), relativement épais, et percé dans sa partie centrale pour le passage et l'adaptation du mécanisme à vis servant à bloquer cette pièce (2) et à l'extraire en vue du démontage du système.As shown in particular in Figure 3b , the fork (20) consists of a rear body (22), relatively thick, and pierced in its central part for the passage and adaptation of the screw mechanism used to block this part (2) and extract it for disassembly of the system.

De ce corps (22) partent deux branches (23), (24), à section en L, les ailes horizontales (25) de ces branches étant parallèles et espacées d'une distance e₁ légèrement supérieure à la distance e₂ séparant le fond des rainures (9) et (10) de la pièce (1).From this body (22) leave two branches (23), (24), of L-section, the horizontal wings (25) of these branches being parallel and spaced by a distance e ₁ slightly greater than the distance e ₂ separating the bottom of the grooves (9) and (10) of the part (1).

Un peu décalée vers l'arrière par rapport au corps (22) la pièce (2) porte le talon (21) d'allure générale verticale, c'est-à-dire perpendiculaire à la fourche (23, 24) et ayant la forme d'une portion de cylindre, dont la surface dirigée vers l'avant (26) est arrondie et la face arrière (27) est plane. Comme il sera expliqué plus en détail ci-après, le volume de ce talon (21) délimité par les faces (26) et (27) vient se loger exactement dans une échancrure correspondante (30) au champ du plateau P, la hauteur du talon étant égale à l'épaisseur dudit plateau P.Slightly offset backwards with respect to the body (22) the part (2) carries the heel (21) of generally vertical appearance, that is to say perpendicular to the fork (23, 24) and having the in the form of a cylinder portion, the forward-facing surface (26) of which is rounded and the rear face (27) is planar. As will be explained in more detail below, the volume of this heel (21) delimited by the faces (26) and (27) is housed exactly in a corresponding notch (30) in the field of the plate P, the height of the heel being equal to the thickness of said plate P.

Pour mieux assurer la mise en place du talon (21) dans ladite échancrure, un téton additionnel (28) dépasse vers l'avant de la face (26) pour venir se placer dans un logement correspondant (29) de ladite échancrure.To better ensure the establishment of the heel (21) in said notch, an additional stud (28) protrudes towards the front of the face (26) to be placed in a corresponding housing (29) of said notch.

On va maintenant décrire la mise en oeuvre du système selon l'invention, en se référant aux figures 1 et 2, ainsi qu'à la figure 5.We will now describe the implementation of the system according to the invention, with reference to FIGS. 1 and 2, as well as to FIG. 5.

En vue du positionnement précis du plateau P sur le bloc A, et du maintien en place de ce positionnement, on fixe en premier lieu la pièce (1) sur la face supérieure F1 du bloc A, en enfonçant à force les tétons (7), (8) dans leurs logements, et en consolidant le tout, éventuellement par une vis insérée dans l'alésage (11) du téton (7).In view of the precise positioning of the plate P on the block A, and of maintaining this positioning in place, the part (1) is first fixed on the upper face F1 of the block A, by forcing the nipples (7) , (8) in their housings, and consolidating the whole, possibly by a screw inserted in the bore (11) of the stud (7).

La pièce (1) offre alors deux glissières (9) et (10), parallèles et orientées avec précision, à la fourche (23, 24) de la pièce (2) avec un jeu minimum, grâce à la correspondance des distances e₁ et e₂.The part (1) then offers two slides (9) and (10), parallel and precisely oriented, at the fork (23, 24) of the part (2) with minimum clearance, thanks to the correspondence of the distances e ₁ and e ₂.

On peut donc insérer la pièce (2) dans la pièce (1) et ensuite mettre en place le plateau P qui repose sur la plaque d'appui (6) de la pièce (1) et dans une échancrure (30) du champ duquel vient s'insérer le talon (21), avec le têton (28) venant s'insérer dans son logement (29).We can therefore insert the part (2) in the part (1) and then set up the plate P which rests on the support plate (6) of the part (1) and in a notch (30) of the field from which the heel (21) is inserted, with the stud (28) coming to be inserted in its housing (29).

Le guidage de la fourche (23, 24) par les rainures (9) et (10), et la coopération du talon (21) et de son téton (28) avec les logements correspondants (29), (30) assurent un positionnement précis et indéréglable du plateau P sur le bloc A.The guidance of the fork (23, 24) by the grooves (9) and (10), and the cooperation of the heel (21) and its stud (28) with the corresponding housings (29), (30) ensure positioning precise and foolproof from plate P to block A.

Comme il a été indiqué au début, et comme il apparaît notamment à la fig. 2, la face arrière (27) du talon (21) est exactement dans le prolongement du champ vertical B du plateau P, de sorte que ce champ ne présente à l'oeil aucune solution de continuité. Du fait que par ailleurs la surface proprement dite du plateau P n'est en aucune façon affectée par le système, la mise en oeuvre de ce dernier garantit le maintien de l'esthétique de l'ensemble mobilier. Cette esthétique se trouve renforcée par l'espace séparant la face supérieure F1 du bloc A et la face inférieure F2 du plateau P, cet espace libre allégeant l'aspect de l'ensemble du plateau et du bloc sur lequel il repose.As indicated at the beginning, and as it appears in particular in FIG. 2, the rear face (27) of the heel (21) is exactly in the extension of the vertical field B of the plate P, so that this field does not present any solution to the eye. Because, moreover, the actual surface of the tray P is in no way affected by the system, the implementation of the latter guarantees the maintenance of the aesthetics of the furniture assembly. This aesthetic is reinforced by the space separating the upper face F1 of the block A and the lower face F2 of the plate P, this free space reducing the appearance of the whole of the plate and of the block on which it rests.

Dans le but d'assurer la stabilité du plateau compte tenu de cet espace, il est prévu de disposer des cales en matière souple telles que représentées en (31) autour de chaque point d'ancrage, pour qu'en ces points le plateau repose toujours sur quatre appuis, au minimum, garantissant la stabilité de l'ensemble.In order to ensure the stability of the plate taking into account this space, it is planned to have shims made of flexible material as shown in (31) around each anchoring point, so that at these points the plate rests always on at least four supports, guaranteeing the stability of the whole.

Comme il a également déjà été indiqué, un avantage essentiel du système selon l'invention est d'offrir la possibilité de réversibilité au plateau, les échancrures (30) étant pratiquées sur chaque champ sans préjuger de la face du plateau qui sera posée sur bloc A.As has already been indicated, an essential advantage of the system according to the invention is to offer the possibility of reversibility to the plate, the notches (30) being formed on each field without prejudging the face of the plate which will be placed on the block. AT.

Enfin, bien que le système se suffise à lui-même par sa conception et sa construction pour le positionnement et le maintien en place du plateau sur le bloc, il est prévu selon l'invention un mécanisme à vis permettant aussi bien de bloquer le système en position montée que d'extraire la pièce (2) pour démonter le système. En effet, la précision du système est telle que, une fois le talon (21) inséré dans l'échancrure (30), l'usager n'a guère de prise pour l'extraire en vue du démontage.Finally, although the system is sufficient in itself by its design and construction for positioning and holding the plate in place on the block, there is provided according to the invention a screw mechanism making it possible to block the system as well in the assembled position than extracting the part (2) to dismantle the system. Indeed, the precision of the system is such that, once the heel (21) inserted into the notch (30), the user has little grip to extract it for disassembly.

Ce mécanisme est illustré à la figure 5, qui est une coupe verticale partielle par le plan de symétrie des pièces (1) et (2), ce couple de pièces (1) et (2) étant assemblées par une vis (40) horizontale les traversant tour à tour en pénétrant par l'orifice (44).This mechanism is illustrated in FIG. 5, which is a partial vertical section through the plane of symmetry of the parts (1) and (2), this pair of parts (1) and (2) being assembled by a horizontal screw (40). passing through them in turn by entering through the orifice (44).

La tête de vis (41) est immobilisée axialement entre l'arrière du corps (22) et une première patte (42) non filetée, puis la vis (40) traverse une seconde patte de guidage (43) également non filetée pour arriver au filetage (13) du sabot (1).The screw head (41) is immobilized axially between the rear of the body (22) and a first unthreaded tab (42), then the screw (40) passes through a second guide tab (43) also unthreaded to reach the thread (13) of the shoe (1).

Quand au moyen d'un outil approprié du genre tournevis introduit dans une fente de la tête (41), on fait tourner la vis dans le sens des aiguilles d'une montre, la vis (40) se visse dans le filetage (13), en rapprochant l'une de l'autre les pièces (1) et (2), les rainures de (1) guidant les branches (25) de la fourche (2), jusqu'à un blocage de l'ensemble du système, la face arrière (27) du talon (21) étant à niveau avec le champ B du plateau P.When by means of a suitable tool of the screwdriver type inserted into a head slot (41), the screw is turned clockwise, the screw (40) is screwed into the thread (13) , bringing the parts (1) and (2) closer to each other, the grooves of (1) guiding the legs (25) of the fork (2), until the whole system is blocked , the rear face (27) of the heel (21) being level with the field B of the plate P.

Dans cette position, il est impossible de dégager le talon (21) du plateau P pour démonter le système. Pour ce démontage, il suffit de tourner la vis (40) en sens contraire : la tête (41) étant immobilisée entre les pattes (42), (22) la rotation de la vis entraînant son déplacement axial vers l'arrière a pour conséquence que c est toute la pièce (2) qui se déplace vers l'arrière, en se dégageant du plateau P.In this position, it is impossible to disengage the heel (21) from the plate P to dismantle the system. For this disassembly, it suffices to turn the screw (40) in the opposite direction: the head (41) being immobilized between the legs (42), (22) the rotation of the screw causing its axial displacement towards the rear has the consequence that it is the whole part (2) which moves backwards, freeing itself from the plate P.

Bien entendu, la description qui précède n'est donnée qu'à titre d'exemple illustratif, et de nombreuses variantes pourront en être conçues, notamment en ce qui concerne la forme respective des divers éléments.Of course, the foregoing description is given only by way of illustrative example, and numerous variants may be conceived thereof, in particular as regards the respective shape of the various elements.

En particulier, on notera que sur les fig. 1, 3a et 3b, le rebord arrière du corps (22) est incliné vers la base de manière que l'ouverture (44) ne soit pas visible de l'extérieur. Il est clair que le rebord arrière pourrait être de niveau avec la face arrière (27) du talon (21) sans que l'on s'écarte de l'invention.In particular, it will be noted that in FIGS. 1, 3 a and 3 b , the rear edge of the body (22) is inclined towards the base so that the opening (44) is not visible from the outside. It is clear that the rear edge could be level with the rear face (27) of the heel (21) without departing from the invention.
