Description

La présente invention concerne un piètement rigide d'assemblage rapide procurant une accessibilité totale autour des pieds, supportant un plateau réversible et muni d'un passage de câbles. Elle concerne également les bureaux à plateau réversible équipés d'un tel piètement.The present invention relates to a rigid base quick assembly providing full accessibility around feet, supporting a reversible tray and provided with a cable passage. It also concerns offices in reversible tray fitted with such a base.

Un piètement de ce type est révélé dans le document EP 125 869 qui décrit un système de bureau particulièrement adapté au passage de câbles grâce à des logements spéciaux disposés entre les montants de chaque pied. Un tel système présente plusieurs inconvénients. Chaque montant tubulaire est coiffé d'une potence sur laquelle est fixé le plateau par des vis pénétrant dans sa face inférieure, ce qui ne permet pas la réversibilité du plateau. De plus, la rigidité de l'ensemble dépend de celle du plateau, à moins de relier les deux pieds par un ou des montants longitudinaux. Or, pour être efficace, de tels montants devront être situés assez bas sous le plateau et limiteront ainsi l'accès sous ce même plateau.A base of this type is revealed in the document EP 125 869 which describes a particularly office system suitable for cable routing thanks to special housings arranged between the uprights of each leg. Such a system has several drawbacks. Each tubular upright is topped with a bracket on which the tray is fixed by screws penetrating into its underside, which does not allow not the reversibility of the plate. In addition, the rigidity of the whole depends on that of the set, unless you connect the two feet by one or more longitudinal uprights. Now, for be effective, such amounts should be set low enough under the tray and thus limit access under the same tray.

Le piètement selon la présente invention permet, en particulier, de remédier à ces inconvénients. A cet effet, il est proposé un piètement rigide à assemblage rapide permettant la fixation d'un plateau réversible, par exemple rectangulaire, comportant deux montants normalement verticaux, reposant directement ou indirectement sur le sol, et disposés à l'aplomb de deux extrémités opposées dudit plateau caractérisé en ce que chaque montant porte à son extrémité supérieure, fixée de manière à ce que son arête soit parallèle à la largeur dudit plateau, un profilé formant cornière inférieure constituée d'une aile horizontale émergeant de la largeur du montant, en direction de l'autre montant et d'une aile verticale reliée à l'aile horizontale par une aile oblique s'étendant depuis l'extérieur du montant par venir se fixer contre l'aile verticale d'une cornière supérieure de direction générale parallèle à celle de la cornière inférieure et de plus grande largeur, dont l'aile horizontale s'étend, au dessus de l'aile verticale, en direction de l'autre montant pour reposer sur la partie supérieure des extrémités de deux longerons horizontaux, fixés perpendiculairement sur les ailes verticales desdites cornières supérieures, et maintenus parallèles entre eux grâce à deux traverses tubulaires fixées perpendiculairement entre lesdits longerons et en retrait de leurs extrémités, de façon à reposer chacune sur l'aile horizontale de la cornière inférieure d'un des montants à laquelle elle est fixée, pour constituer un châssis rigide sur lequel vient reposer le plateau, bloqué en translation dans le plan horizontal par emboítement de l'épaisseur des ailes horizontales des cornières supérieures dans un évidement inférieur correspondant, pratiqué à chacune des extrémités de la face intérieure dudit plateau.The base according to the present invention allows, in particular, to remedy these drawbacks. To this end, it a rigid base with quick assembly is proposed allowing the attachment of a reversible plate, for example rectangular, with two uprights normally vertical, resting directly or indirectly on the ground, and arranged vertically at two opposite ends of said tray characterized in that each upright carries its upper end, fixed so that its edge either parallel to the width of said plate, a profile forming angle iron lower consists of a horizontal wing emerging from the width of the upright, towards the other upright and one vertical wing connected to the horizontal wing by an oblique wing extending from the outside of the upright by coming to be fixed against the vertical wing an upper angle of general direction parallel to that of the lower and larger angle, whose horizontal wing extends, above the wing vertical, towards the other upright to rest on the upper part of the ends of two beams horizontal, fixed perpendicularly on the wings vertical of said upper angles, and maintained parallel to each other thanks to two fixed tubular sleepers perpendicularly between said beams and set back from their ends, so as to rest each on the wing horizontal of the lower angle of one of the uprights to which it is fixed to form a rigid frame on which the plate rests, blocked in translation in the horizontal plane by nesting the thickness of horizontal wings of the upper angles in a corresponding lower recess, made in each of the ends of the inner face of said tray.

Un tel piètement permet d'utiliser un plateau ne possédant pas une rigidité intrinsèque élevée, puisque ce dernier ne participe pas à la rigidité de l'ensemble. De plus, un tel piètement permet d'utiliser un plateau réversible. Il suffit pour cela de pratiquer des évidements symétriques sur chacune des faces du plateau.Such a base makes it possible to use a table only not having high intrinsic rigidity, since this the latter does not participate in the rigidity of the whole. Of more, such a base allows the use of a tray reversible. It is enough to practice recesses symmetrical on each side of the plate.

On décrira ci-après, à titre d'exemple non limitatif, diverses formes d'exécution de la présente invention en référence au dessin annexé sur lequel :

  • la figure 1 est une vue partielle en perspective éclatée, partiellement transparente, du plateau monté sur le piètement selon l'invention,
  • la figure 2 est une vue en coupe selon l'axe de symétrie longitudinal du plateau de la figure 1,
Various embodiments of the present invention will be described below, by way of non-limiting example, with reference to the appended drawing in which:
  • FIG. 1 is a partial exploded perspective view, partially transparent, of the plate mounted on the base according to the invention,
  • FIG. 2 is a sectional view along the longitudinal axis of symmetry of the plate of FIG. 1,

Le piètement 1 selon l'invention, supportant un plateau 2 réversible, par exemple rectangulaire, comme représenté sur la figure 2, comporte principalement deux montants 3 normalement verticaux, reposant directement ou indirectement sur le sol, et disposés à l'aplomb de deux extrémités opposées dudit plateau 2. Chaque montant 3 porte, à son extrémité supérieure, fixée de manière à ce que son arête soit parallèle à la largeur dudit plateau 2, une cornière inférieure 4. Cette cornière inférieure 4, qui peut, par exemple être soudée au montant 3, présente une aile horizontale 4a émergeant de la largeur du montant 3, en direction de l'autre montant 3 et une aile verticale 4b s'étendant depuis l'extérieur du montant 3 vers le haut. Ces deux ailes 4a, 4b peuvent se rejoindre directement selon une arête unique ou, selon une variante particulière représentée sur la figure 1, être reliées par une aile oblique 4c. L'aile verticale 4b s'élargit vers le haut pour constituer l'aile verticale 5b d'une cornière supérieure 5 de direction générale parallèle à celle de la cornière inférieure 4 et de plus grande largeur, dont l'aile horizontale 5a s'étend, en direction de l'autre montant 3, au dessus de l'aile verticale 5b. Cet ensemble constitué des deux cornières inférieure 4 et supérieure 5 peut être constitué d'une pièce monobloc obtenue par découpage et par pliage ou bien provenir de l'assemblage de cornières indépendantes. Dans ce dernier cas, l'aile verticale 4b pourra être prolongée, en direction de l'autre montant 3, par un rebord horizontal qui servira d'appui à l'aile horizontale 5a, facilitant ainsi la mise en place et l'assemblage des deux cornières inférieure 4 et supérieure 5, comme il est représenté sur la figure 1. L'aile horizontale 5a de ladite cornière supérieure 5 repose sur la partie supérieure des extrémités 6a de deux longerons 6 horizontaux fixés perpendiculairement sur les ailes verticales 5b desdites cornières supérieures 5, par tout moyen, connu de l'homme du métier, procurant une grande rigidité au montage. Un tel moyen peut constituer, par exemple, dans le cas où les longerons 6 sont tubulaires, en un vissage des ailes verticales 5b sur une noix intérieure 7 à tampons tangents disposée à l'intérieur de chacune des extrémités 6a desdits longerons 6, comme représenté sur la figure 1. Ces longerons 6 sont par ailleurs maintenus parallèles entre eux grâce à deux traverses 8 fixées, par exemple soudées, perpendiculairement entre lesdits longerons 6. Chaque traverse 8 est fixée en retrait des extrémités 6a entre les longerons 6 de façon à reposer, par son milieu, sur l'aile horizontale 4a de la cornière inférieure 4 d'un des montants 3 sur laquelle elle est fixée, constituant ainsi un châssis rigide sur lequel vient reposer le plateau 2. Selon une variante particulière, chacune des deux traverses 8 est tubulaire et munie, au milieu de sa face inférieure 8a de deux trous oblongs 9a élargis en leur centre par un trou circulaire de diamètre supérieur à la largeur dudit trou oblong 9a, auxquels correspondent, sur l'aile horizontale 4a de la cornière inférieure 4 de chaque montant 3 deux trous 9b dans lesquels sont enfilés deux clés 10 à serrage rapide venant solidariser ladite traverse 8 avec ladite aile 4a. Ces clés 10 peuvent, par exemple, être du type constitué d'une tête 10a en "clé à violon" reliée à l'épaulement d'un bouton moleté 10b par un axe de diamètre égal à celui de la partie circulaire des trous oblongs 9a et 9b, comme représenté sur la figure 1. Ces clés contribuent au montage et au démontage rapide du piètement 1. En effet, il suffit de les introduire avec leur tête 10a parallèle au grand axe du trou oblong 9a pour amener l'épaulement au contact des parois dudit trou oblong 9a, puis de faire subir au bouton moleté 10b resté à l'extérieur une rotation de 90° pour provoquer le blocage. Le déblocage sera obtenu en effectuant ces mêmes opérations dans l'ordre inverse.The base 1 according to the invention, supporting a reversible plate 2, for example rectangular, as shown in FIG. 2, mainly comprises two uprights 3 normally vertical, resting directly or indirectly on the ground, and arranged vertically at two ends opposite of said plate 2. Each upright 3 carries, at its upper end, fixed so that its edge is parallel to the width of said plate 2, a lower angle 4. This lower angle 4, which can, for example be welded to upright 3 has a horizontal wing 4 has emerging from the width of upright 3, towards the other upright 3 and a vertical wing 4 b extending from the outside of amount 3 upwards. These two wings 4, 4b can be joined directly or by means of one edge, according to a particular embodiment shown in FIG 1, be connected by an oblique wing 4 c. The vertical wing 4 b widens upwards to constitute the vertical wing 5 b of an upper angle 5 of general direction parallel to that of the lower angle 4 and of greater width, including the horizontal wing 5 a extends, in the direction of the other upright 3, above the vertical wing 5 b . This assembly consisting of the two lower angles 4 and upper 5 may consist of a single piece obtained by cutting and folding or else come from the assembly of independent angles. In the latter case, the vertical wing 4 b may be extended, in the direction of the other upright 3, by a horizontal flange which will serve as a support for the horizontal wing 5 a , thus facilitating the positioning and assembly of the two lower 4 and upper 5 angles, as shown in FIG. 1. The horizontal wing 5 a of said upper angle 5 rests on the upper part of the ends 6 a of two horizontal beams 6 fixed perpendicularly to the vertical wings 5 b of said upper angles 5, by any means known to those skilled in the art, providing great rigidity in mounting. Such a means can constitute, for example, in the case where the longitudinal members 6 are tubular, in a screwing of the vertical wings 5b on an inner nut 7 with tangent buffers disposed inside each of the ends 6 has said longitudinal members 6, as shown in Figure 1. These longitudinal beams 6 are also kept mutually parallel by two crosspieces 8 fixed, for example welded perpendicularly between said side rails 6. Each cross member 8 is secured recessed of the ends 6a between the side members 6 of so as to rest, through its center, on the horizontal wing 4 a of the lower angle 4 of one of the uprights 3 on which it is fixed, thus constituting a rigid frame on which the plate 2 rests. According to a particular variant, each of the two crosspieces 8 is tubular and provided, in the middle of its lower face 8 a with two oblong holes 9 has widened in their center by a circular hole of diameter greater than the wide one ur of said oblong hole 9 a , to which correspond, on the horizontal wing 4 a of the lower angle 4 of each upright 3 two holes 9 b in which are threaded two quick-tightening keys 10 fastening said cross member 8 with said wing 4 a . These keys 10 can, for example, be of the type consisting of a head 10a in "violin key" connected to the shoulder of a knurled button 10b by an axis of diameter equal to that of the circular part of the oblong holes 9 a and 9 b , as shown in FIG. 1. These keys contribute to the rapid assembly and disassembly of the base 1. Indeed, it suffices to introduce them with their head 10 a parallel to the major axis of the oblong hole 9 a to bring the shoulder in contact with the walls of said oblong hole 9a, and then to subject the knurled knob 10 b stayed outside a rotation of 90 ° to cause blocking. The release will be obtained by performing these same operations in reverse order.

Cette disposition assure une très grande rigidité en torsion du piètement 1. En particulier, l'échelle il constituée des longerons 6 et des traverses 8 est fixée selon trois axes sur chaque support 12 constitué d'un montant 3 et des deux cornières inférieure 4 et supérieure 5, deux axes horizontaux parallèles O1 et O2 correspondant aux axes des longerons 6 et un axe vertical O3 perpendiculaire et équidistant des deux précédents, situé au milieu desdits trous 9a. Cette triangulation procure au piètement 1 une très grande résistance à la rotation des supports 12 par rapport à l'échelle il autour d'un axe horizontal quelconque situé dans le plan de l'échelle 11 et passant par l'axe vertical des supports 12, et par conséquent une très grande rigidité intrinsèque indépendante des caractéristiques mécaniques dudit plateau 2. De plus, ce dernier est bloqué en translation dans le plan horizontal par emboítement de l'épaisseur des ailes horizontales 5a des cornières supérieures 5 dans un évidement inférieur 13a correspondant, pratiqué à chacune des extrémités de la face inférieure 2a dudit plateau. Afin de permettre la réversibilité du plateau 2, celui-ci est fixé au piètement 1 par vissage à travers ce même plateau 2, sur les ailes horizontales 5a des cornières supérieures 5, de deux plaques de fixation 14a encastrées chacune à une extrémité de la face supérieure 2b dudit plateau 2 dans un évidement supérieur 13b symétrique de l'évidement inférieur 13a par rapport au plan dudit plateau 2. Les deux plaques de fixation 14a encastrées permettent d'augmenter la résistance au basculement du plateau 2 sur le piètement 1 tout en procurant une face supérieure 2b dudit plateau 2 parfaitement plane. Le retournement du plateau 2 pourra s'effectuer, sans modifier sa disposition par rapport au piètement 1, par rotation autour de l'axe de symétrie longitudinale dudit plateau 2 si les évidements 13 sont symétriques par rapport à cet axe, par rotation autour de l'axe de symétrie transversale dudit plateau 2 si les évidements 13 sont symétriques par rapport à cet axe. Bien évidemment, on pourra toujours retourner le plateau 2, même si le positionnement des évidements 13 n'est pas symétrique, mais on obtiendra alors une modification de la disposition du plateau 2 par rapport au piètement 1.This arrangement provides very high torsional rigidity of the base 1. In particular, the ladder made up of side members 6 and cross members 8 is fixed along three axes on each support 12 made up of an upright 3 and two lower angles 4 and upper 5, two parallel horizontal axes O 1 and O 2 corresponding to the axes of the side members 6 and a vertical axis O 3 perpendicular and equidistant from the previous two, located in the middle of said holes 9 a . This triangulation provides the base 1 with very high resistance to rotation of the supports 12 relative to the scale 11 about any horizontal axis situated in the plane of the scale 11 and passing through the vertical axis of the supports 12, and therefore a very high intrinsic rigidity independent of the mechanical characteristics of said plate 2. In addition, the latter is blocked in translation in the horizontal plane by interlocking the thickness of the horizontal wings 5 has upper angles 5 in a lower recess 13 a corresponding, made at each end of the lower face 2 a of said plate. In order to enable the reversibility of the plate 2, the latter is fixed to the base 1 by screwing through the same plate 2, on the wings 5 has upper brackets 5, two mounting plates 14 fitted to each at one end of the upper face 2 b of said plate 2 in an upper recess 13 b symmetrical with the lower recess 13 a with respect to the plane of said plate 2. The two fixing plates 14 has recessed make it possible to increase the resistance to tilting of the plate 2 on the base 1 while providing an upper face 2 b of said plate 2 perfectly flat. The tray 2 can be turned over, without modifying its arrangement with respect to the base 1, by rotation about the longitudinal axis of symmetry of said tray 2 if the recesses 13 are symmetrical with respect to this axis, by rotation around the 'axis of transverse symmetry of said plate 2 if the recesses 13 are symmetrical with respect to this axis. Obviously, we can always turn over the plate 2, even if the positioning of the recesses 13 is not symmetrical, but we will then obtain a modification of the arrangement of the plate 2 relative to the base 1.

Selon une variante particulière, les évidements inférieurs 13a, supérieurs 13b débouchent respectivement latéralement à la face inférieure 2a, supérieure 2b dudit plateau 2 pour converger en un évidement latéral 13c réalisé dans le flan latéral 2c dudit plateau 2. Dans cet évidement latéral 13c est encastrée une aile verticale 14b prolongeant vers le bas chacune des plaques de fixation 14a pour former une cornière extérieure 14 de forme complémentaire de celle de la cornière supérieure 5. Les deux cornières supérieure 5 et extérieure 14 pincent donc le plateau 2 entre leurs ailes horizontales respectives 5a, 14a et sont en appui l'une contre l'autre par leurs ailes verticales 5b, 14b. Cette configuration améliore le maintien du plateau 2 sur le piètement 1, mais surtout, permet de réaliser sur les évidements latéraux 13c, les ailes verticales 5b des cornières supérieures 5 et les ailes verticales 14b des cornières extérieure 14, des renfoncements verticaux respectifs 13d,5d,14d, correspondants s'emboítant les uns dans les autres et réalisés, par exemple, sous la forme d'arrondis. Le renfoncement vertical 14d des ailes verticales 14b des cornières extérieures 14, permet le passage de câbles, comme des câbles informatiques, que l'on pourra dissimuler par un cache adapté, non représenté sur les figures. Ce passage peut, selon une variante particulière être prolongé vers le bas par l'espace situé entre deux tubes verticaux et parallèles constituant les montants 3. Un tel passage de câbles, qui peut s'ouvrir sur toute sa longueur est particulièrement avantageux lorsque les câbles à installer sont munis de prises dont l'encombrement est trop important pour permettre l'enfilage desdits câbles à travers le passage qui leur est généralement réservé. De plus, en disposant côte à côte, deux bureaux équipés du piètement selon l'invention, on peut apparier deux renfoncements 14d pour former un seul passage de câbles de dimension plus importante.According to a particular variant, the lower recesses 13 a , upper 13 b respectively open laterally to the lower face 2 a , upper 2 b of said plate 2 to converge into a lateral recess 13 c produced in the lateral blank 2 c of said plate 2. In this lateral recess 13 c is embedded a vertical wing 14 b extending downwards each of the fixing plates 14 a to form an external angle 14 of a shape complementary to that of the upper angle 5. The two upper 5 and external 14 angles therefore pinch the plate 2 between their respective horizontal flanges 5a, 14a and are supported against one another by their vertical flanges 5 b, 14 b. This configuration improves the retention of the plate 2 on the base 1, but above all, makes it possible to produce on the lateral recesses 13 c , the vertical wings 5 b of the upper angles 5 and the vertical wings 14 b of the external angles 14, respective vertical recesses 13 d , 5 d , 14 d , correspondents fitting into each other and produced, for example, in the form of roundings. The vertical recess 14 d of the vertical wings 14 b of the external angles 14, allows the passage of cables, such as computer cables, which can be concealed by a suitable cover, not shown in the figures. This passage can, according to a particular variant, be extended downwards by the space situated between two vertical and parallel tubes constituting the uprights 3. Such a cable passage, which can open over its entire length, is particularly advantageous when the cables to be installed are provided with sockets which are too large to allow threading of said cables through the passage which is generally reserved for them. In addition, by having side by side, two desks equipped with the base according to the invention, one can pair two recesses 14 d to form a single passage of cables of larger dimension.

Bien entendu, toute la description qui vient d'être donnée d'un bureau à plateau rectangulaire peut être adaptée à des plateaux de toutes formes : carrée, oblongue et même ronde, moyennant de simples adaptations tout à fait à la portée de l'homme du métier ayant une habileté moyenne.Of course, all the description that has just been data of a rectangular desk can be adapted to trays of all shapes: square, oblong and even round, with simple adaptations entirely to the scope of the skilled person with average skill.
