ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Les meubles de laboratoire sont des produits très spéciaux et très coûteux, du fait qu'ils doivent être prévus pour permettre d'y intégrer des équipements pour l'alimentation en gaz, en eau, et en électricité, des moyens de communications d'informations orales et de données, ainsi que des équipements pour vidanger des liquides et évacuer des fumées et gaz. D'un autre côté, les matériaux qui doivent être employés pour leurs constructions ne peuvent pas être quelconques, puisqu'ils doivent être résistants à divers agents chimiques, ignifugés et faciles à nettoyer, entre autres particularités.Laboratory furniture is a very special and very expensive product because it must be designed to allow the integration of equipment for the supply of gas, water and electricity, means of communication of information. and data, as well as equipment for draining liquids and evacuating fumes and gases. On the other hand, the materials that must be used for their constructions can not be must be resistant to various chemical agents, flame retardant and easy to clean, among other features.

Actuellement, on connaît différents modes de construction de meubles de laboratoire ; certains ont la caractéristique commune de constituer des tables de travail indépendantes qui sont assemblées par simple juxtaposition ou qui comprennent un pied commun entre deux tables, et sur ces tables de travail, sont constituées des structures verticales d'étagères fixées à la table de travail elle-même où au mur, ces étagères, étant par ailleurs destinées à la disposition des bornes d'alimentation, appareils et outils dont on a besoin sur le poste de travail en question.At present, different methods of constructing laboratory furniture are known; some have the common characteristic of constituting independent work tables which are assembled by simple juxtaposition or which include a common foot between two tables, and on these work tables are constituted by vertical structures of shelves fixed to the work table. - even on the wall, these shelves, being also intended for the provision of power terminals, devices and tools that are needed on the workstation in question.

Ces modes de construction connus sont peu adaptables, de sorte que les changements de distribution des postes de travail ou de nature de travaux à réaliser sur ces derniers nécessitent fréquemment de construire un nouveau meuble ou de se servir d'un meuble qui ne répond pas aux besoins du poste de travail et nous rappelons que ces meubles sont d'un prix élevé.These known methods of construction are not very adaptable, so that changes in the distribution of workstations or nature of work to be performed on them often require the construction of a new piece of furniture or use a piece of furniture that does not meet the needs of the workstation and we recall that these furniture are of a high price.

an electrical trunking, front flanges, tray feeds, top feeders, tower feeders, liquid pickups, hanging showcases, grilles; where: the uprights in metal profiles extend from the ground over the entire height of the wall cabinet and they have, both on their vertical fields and on their sides, means that can be used to fix said first, second and third supports and the following supports at the same time on their front and rear sides, as well as these amounts of metal profiles can support between them the vertical frame, the upper and lower gutters, the additional worktop, the shelves without protruding and protruding , tower feeders, liquid collecting bowls, hanging cabinets and grilles; the first supports are fixed to the feet of the metal profile uprights and rest on the ground; the second supports can be attached to the choice at least two ergonomic levels separate from the amounts of metal profiles; the horizontal frame is fixed between the second supports; the worktop is fixed to the horizontal frame; the vertical access frame is fixed between the metal profile uprights and supports the upper and lower gutters which are coupled horizontally to the respective upper and lower edges of the vertical frame and extend between the two metal profile uprights, the upper gutter incorporating the supplemental worktop which is coupled to the upper gutter of the vertical frame and includes supply elements, sinks and draining means; and the following third supports and supports can be selectively attached at various heights of the metal profile posts.

Avec cette constitution, le système proposé rend possible la construction d'une structure qui intègre la table de travail et l'étagère. En supplément, la construction des composants structuraux et leur sélection permettent d'obtenir une construction simple, pouvant être assemblée comme s'il s'agissait d'un jeu de meccano, en employant des moyens de fixation simples et des outils élémentaires ; en même temps qu'ils assurent une grande adaptabilité aux applications.With this constitution, the proposed system makes possible the construction of a structure that integrates the work table and shelf. In addition, the construction of the structural components and their selection allow to obtain a simple construction, being able to be assembled as if it were a game of meccano, by using simple fixing means and elementary tools; at the same time as they ensure great adaptability to applications.

Dans ce système de construction, la gouttière supérieure du bâti vertical est destinée à incorporer les éviers et les moyens de vidange nécessaires ; tandis que la gouttière inférieure du bâti vertical supporte les canalisations d'alimentation en eau et en gaz ; les moyens d'alimentation électrique sont réalisés au moyen d'un chemin de câbles électriques, auquel sont reliés une galerie d'alimentations, un luminaire avec interrupteur double prise, des bornes de communication orale et d'échange de données, et d'une cloison intérieure de séparation pour le câblage nécessaire. C'est-à-dire que le meuble-étagère constitué selon l'invention prévoit la séparation correcte des différents types d'alimentation nécessaires, conformément aux normes de sécurité en vigueur.In this construction system, the upper gutter of the vertical frame is intended to incorporate the sinks and the necessary emptying means; while the lower gutter of the vertical frame supports the water supply pipes and gas; the power supply means are made by means of an electrical cable tray, to which are connected a feed gallery, a luminaire with double-jack switch, terminals for oral communication and data exchange, and a internal partition wall for the necessary wiring. That is to say, the shelf unit constituted according to the invention provides for the correct separation of the different types of power supply required, in accordance with the safety standards in force.

Une autre particularité de l'invention consiste en ce que le bâti vertical d'accès est muni de portes d'accès coulissantes ou battantes, de manière qu'on dispose d'un accès rapide et commode aux moyens d'alimentations et à leurs moyens de mesure et de contrôle (compteurs, pressostats, etc.), disposés de façon dissimulée derrière ledit bâti vertical d'accès.Another feature of the invention is that the vertical access frame is provided with sliding or hinged access doors, so that there is a quick and convenient access to power means and their means measuring and control (counters, pressure switches, etc.), arranged concealed behind said vertical access frame.

Egalement selon l'invention, les bordures frontales sont des profilés qui sont accouplés aux bords longitudinaux des tablettes en porte à faux ou non, et qui font convenablement saillie par rapport à leur plan supérieur. De telles bordures sont destinées à empêcher la chute des éléments déposés sur les tablettes ; lorsque ces éléments peuvent produire des écoulements de liquide, les tablettes en porte à faux ou non sont remplacées par les cuvettes collectrices de liquides. De même, les bordures peuvent être placées de telle manière que la tablette soit au ras dudit profilé pour placer des appareils d'instrumentation.Also according to the invention, the front edges are profiles which are coupled to the longitudinal edges of the shelves cantilevered or not, and which properly protrude from their upper plane. Such borders are intended to prevent the falling of the elements deposited on the shelves; when these elements can produce liquid flows, the shelves cantilevered or not are replaced by the liquid collecting bowls. Similarly, the borders can be placed in such a way that the tablet is flush with said profile to place instruments of instrumentation.

En plus de la simplicité de construction et de conception du système proposé, il convient de remarquer que les premiers et deuxièmes supports sont identiques entre eux, sauf qu'ils sont montés dans des positions retournées de 180 ° pour que les premiers supports constituent des pattes d'appui des montants en profilés métalliques et que les deuxièmes supports jouent le rôle de supports de soutien du plan de travail. En supplément, les troisièmes supports et les supports suivants répondent au même concept de conception que les premiers et deuxièmes supports, sauf qu'ils sont de longueurs différentes.In addition to the simplicity of construction and design of the proposed system, it should be noted that the first and second supports are identical to each other, except that they are mounted in positions turned up by 180 ° so that the first supports constitute legs support of the amounts of metal profiles and that the second supports play the role of support supports of the work plan. In addition, the third supports and the following supports meet the same concept of design as the first and second supports, except that they are of different lengths.

Certaines variantes de réalisation sont destinées aux moyens prévus pour régler à volonté la position en hauteur du plan de travail, qui sont des moyens de réglage sélectivement variable de façon continue ou discontinue.Some embodiments are intended for the means provided to adjust at will the height position of the work plane, which are selectively variable adjustment means continuously or discontinuously.

En ce qui concerne les moyens de réglage continu, un mode de réalisation du dispositif de réglage en hauteur sélectivement variable consiste en ce que les montants possèdent, sur leurs bords verticaux, des cannelures longitudinales qui sont plus étroites sur leur côté longitudinal ouvert qu'à leur intérieur et qui, dans cet intérieur, peuvent recevoir des arrêts à pression montés dans les deuxièmes supports. En utilisant des cannelures verticales telles que celles indiquées, l'invention envisage deux autres variantes de réalisation : la première consiste en ce que ces cannelures verticales incorporent intérieurement, et avec ajustement glissant, une plaquette munie de trous filetés pour des premières vis respectives montées dans les deuxièmes supports ; et la deuxième consiste en ce que les cannelures verticales sont des parties constitutives de moyens d'accouplement glissants qui sont complémentaires d'autres qui existent dans les deuxièmes supports, ces deuxièmes supports sont réunis au bâti horizontal et ce bâti horizontal est fixé à l'extrémité d'un piston qui fait partie d'un cylindre à fluide vertical. Un autre mode de réalisation qui n'est pas basé sur des cannelures verticales consiste en ce qu'il est prévu des crémaillères dentées verticales qui sont fixées aux montants et dans lesquelles s'engrènent des pignons motorisés qui sont fixés aux deuxièmes supports.With regard to the continuous adjustment means, one embodiment of the selectively variable height adjustment device consists in that the uprights have, on their vertical edges, longitudinal grooves which are narrower on their open longitudinal side than on their interior and which, in this interior, can receive pressure stops mounted in the second supports. By using vertical splines such as those indicated, the invention contemplates two other variants of embodiment: the first consists in that these vertical splines incorporate internally, and with sliding adjustment, a plate provided with threaded holes for respective first screws mounted in the second supports; and the second is that the vertical splines are constituent parts of sliding coupling means which are complementary to others which exist in the second supports, these second supports are joined to the horizontal frame and this horizontal frame is attached to the end of a piston which is part of a vertical fluid cylinder. Another embodiment which is not based on vertical splines is that there are vertical toothed racks which are fixed to the uprights and in which meshing motorized gears are attached to the second supports.

En ce qui concerne les moyens de réglage en hauteur de façon discontinue, le présent brevet d'addition envisage deux possibilités. Une première possibilité consiste en ce que les champs verticaux des montants possèdent, avec une distribution appropriée, une pluralité de trous filetés pour des deuxièmes vis respectives qui sont montées dans les deuxièmes supports. La deuxième possibilité est celle dans laquelle les champs verticaux des montants présentent un rainurage possédant un pas approprié entre les rainures consécutives, tandis que les deuxièmes supports possèdent une paire de nervures susceptibles d'être accouplés dans des rainures correspondantes dudit rainurage, consécutives ou non.With regard to the height adjustment means in a discontinuous manner, the present patent of addition envisages two possibilities. A first possibility is that the vertical fields of the uprights have, with appropriate distribution, a plurality of threaded holes for respective second screws which are mounted in the second supports. The second possibility is that in which the vertical fields of the uprights have a groove having a suitable pitch between the consecutive grooves, while the second supports have a pair of ribs that can be coupled in corresponding grooves of said grooving, consecutive or not.

Sur la figure 1, on représente une variante de réalisation munie de deux tablettes avec saillie (13) et une goulotte électrique dans lequel sont intégrés (figure 3 à 6) une galerie d'alimentations (23), un luminaire avec interrupteur, des prises doubles, des bornes de communication d'informations orales et d'échange de données, en supplément d'incorporer une cloison interne de séparation pour le câblage nécessaire ; sur les figures 5 et 6, on peut voir la disposition de cette cloison interne de séparation pour le câblage. Sur la figure 1, on observe aussi les portes coulissantes ou abattantes (11) pour le bâti vertical (6), ainsi qu'un supplément de plan de travail (10) qui est doté de deux éviers (22) disposés au droit d'arrivées de liquides qui sont produites au moyen des alimentations supérieures (17), comme le montre la figure 2, au moyen d'alimentations de plateau (16), comme le montre la figure 12 ou, y compris, par la combinaison d'alimentations de plateau (16) et supérieures (17) comme on le voit sur les figures 13 et 14.FIG. 1 shows an alternative embodiment provided with two protruding shelves (13) and an electrical trough in which are integrated (FIGS. 3 to 6) a feed gallery (23), a luminaire with switch, sockets dual, oral information communication and data exchange terminals, in addition to incorporating an internal partition for the necessary wiring; in FIGS. 5 and 6, the arrangement of this internal partition wall for the wiring can be seen. In Figure 1, there are also sliding or flap doors (11) for the vertical frame (6), and an additional worktop (10) which is provided with two sinks (22) arranged at right liquid inflows which are produced by means of the upper feeds (17), as shown in Figure 2, by means of tray feeds (16), as shown in Figure 12 or, including, by the combination of feeds of tray (16) and upper (17) as seen in Figures 13 and 14.

Les figures 3 à 8 illustrent des sous-ensembles rapportés à l'ensemble d'une goulotte avec luminaire (14) accouplée dans sa partie inférieure à des tablettes en porte à faux (13), à fond distinct qui sont fixées entre une paire de troisièmes supports (4) et terminées par des bordures frontales respectives (15) qui empêchent ou rendent plus difficile la chute accidentelle des objets déposés sur ces tablettes, dans le cas où l'on prévoit des déversements de liquides, les tablettes en porte à faux (13) ou non (12) peuvent être remplacées par des cuvettes collectrices de liquides (19) en forme de bassins, comme celle qui est représentée sur la figure 9. La réalisation de la figure 14 est analogue à celle de la figure 13, mais avec une goulotte électrique différente, munie d'un luminaire (14).Figures 3 to 8 illustrate subassemblies reported to the assembly of a chute with luminaire (14) coupled in its lower part to shelves in cantilever (13), which are fixed between a pair of third supports (4) and terminated by respective front edges (15) which prevent or make more difficult the accidental fall of the objects deposited on these tablets, in the in the event of liquid spills, the cantilevered (13) or non-collapsed (12) shelves may be replaced by basin-like liquid collecting cups (19), as shown in the figure 9. The embodiment of Figure 14 is similar to that of Figure 13, but with a different electrical chute, provided with a luminaire (14).

Les bordures frontales (15) sont des profilés qui sont accouplés aux bords longitudinaux des tablettes en porte à faux (13) ou non (12), au ras du plan supérieur de ces tablettes ou en formant un rebord.The front edges (15) are profiles that are coupled to the longitudinal edges of the cantilevered shelves (13) or not (12), flush with the upper plane of these shelves or forming a flange.

Comme on le voit sur les figures 10 et 11, la bordure frontale (15) peut être montée sur l'avant de la tablette en porte à faux ou non (12 ou 13) ; sur la figure 10, l'accouplement est réalisé en constituant un rebord qui empêchera la chute des appareils et récipients situés sur la tablette avec ou sans saillie (12 ou 13), tandis que, sur la figure 11, la bordure frontale (15) est au ras de la surface de la tablette. L'un ou l'autre montage est obtenu par simple rotation de 180 ° de la bordure frontale (15) et par accouplement de la nervure asymétrique (24) de la bordure frontale (15).As seen in Figures 10 and 11, the front edge (15) can be mounted on the front of the shelf cantilevered or not (12 or 13); in Figure 10, the coupling is formed by forming a rim which will prevent the falling of the apparatus and containers on the shelf with or without protrusion (12 or 13), whereas in Figure 11 the front edge (15) is flush with the surface of the tablet. One or the other assembly is obtained by simple rotation of 180 ° of the front edge (15) and by coupling of the asymmetrical rib (24) of the front edge (15).

Les deuxièmes supports (3) sont réglables en hauteur le long du montant en profilé métallique, de sorte que le plan de travail l'est aussi, ce qui nous permet d'adapter facilement la position ergonomique du plan de travail aussi bien à l'élément concret ou à la fonction qui va se réaliser sur ce lieu spécifique, qu'à la position de travail la plus idoine pour le ou les usagers.The second supports (3) are adjustable in height along the metal profile upright, so that the worktop is also, which allows us to easily adapt the ergonomic position of the worktop as well to the concrete element or function that will be realized on this specific place, that the most suitable working position for the user or users.

Pour une quelconque des tablettes avec ou sans saillie (12 ou 13) il est prévu qu'elle possède une configuration de cuvette collectrice de liquides (19).For any of the protruding or non-protruding tablets (12 or 13) it is provided that it has a liquid collecting cup configuration (19).

Pour les applications dans lesquelles on exige un degré spécial de propreté, comme dans ce qu'on appelle "les salles blanches", il est prévu l'emploi d'un panneau post-formé dépourvu d'arête ; comme on le représente sur la figure 15.For applications in which a special degree of cleanliness is required, as in the so-called "clean rooms", the use of a post-formed panel without a ridge is foreseen; as shown in Figure 15.

Les figures 18 et 20 montrent diverses réalisations équipées d'alimentations en tour (18) qui incorporent en elles-mêmes aussi bien des alimentations liquides que des alimentations électriques, de gaz, ou des moyens de communication d'informations orales ou d'échange de données. La réalisation de la figure 18 comprend une seule tablette sans saillie (12), celle de la figure 19 dispose de deux tablettes sans saillie (12) et celle de la figure 18 comprend en supplément une vitrine suspendue (20).Figures 18 and 20 show various embodiments equipped with tower feeders (18) which incorporate in themselves liquid feeds as well as power supplies, gas, or means of oral information communication or exchange of information. data. The embodiment of FIG. 18 comprises a single non-protruding shelf (12), that of FIG. 19 has two protruding shelves (12) and that of FIG. 18 additionally comprises a suspended window (20).

Les figures 19 et 20 montrent des réalisations qui comprennent des grilles (21) destinées à réaliser sur elles des montages de circuits ou de dispositifs à étudier. Sur ces figures, le plan de travail (9) est à un niveau plus bas que dans les réalisations indiquées précédemment.Figures 19 and 20 show embodiments which comprise grids (21) intended to carry on them assemblies of circuits or devices to be studied. In these figures, the work plane (9) is at a lower level than in the embodiments indicated above.

La figure 21 montre une réalisation double, en ce sens que, sur des mêmes montants en profilés métalliques (1), on a formé une structure de meuble-étagère portant deux postes de travail face à face.Figure 21 shows a dual embodiment, in that on the same amounts of metal profiles (1), there is formed a furniture-shelf structure with two work stations facing each other.

D'autres caractéristiques sont expliquées ci-après en se reportant aux figures 22 à 28 de la représentation graphique annexée ; elles se réfèrent à des variantes de moyens de réglage sélectivement variable de la hauteur du plan de travail (9) pour les meubles-étagères de laboratoire qui sont constitués selon le système de construction dont la configuration représentée sur la figure annexée est un exemple purement illustratif.Other characteristics are explained below with reference to FIGS. 22 to 28 of the appended graphical representation; they refer to variants of selectively variable adjustment means of the height of the worktop (9) for laboratory furniture-shelves which are constituted according to the construction system whose configuration shown in the attached figure is a purely illustrative example .

Les' figures 23 à 26 représentent des variantes respectives de moyens de réglage qui sont de ceux qui rendent possible un réglage continu. La variante représentée sur la figure 23 consiste en ce que les montants (1) présentent sur leurs champs verticaux des cannelures longitudinales (25) qui sont plus étroites sur leur côté longitudinal ouvert que dans leur intérieur et qui, dans cet intérieur, peuvent recevoir des arrêts à pression (26) montés sur les deuxièmes supports (3).Figs. 23 to 26 show respective variants of adjustment means which are of those which make continuous adjustment possible. The variant shown in FIG. 23 is that the uprights (1) have on their vertical fields longitudinal grooves (25) which are narrower on their open longitudinal side than in their interior and which, in this interior, can receive pressure stops (26) mounted on the second supports ( 3).

Dans la solution que montre la figure 24, il existe des cannelures longitudinales (25) comme les précédentes, mais qui incorporent dans leur intérieur et avec ajustement glissant, une plaquette (27) dotée de trous filetés (28) prévues pour des premières vis (29) montées sur les deuxièmes supports (3).In the solution shown in FIG. 24, there are longitudinal grooves (25) like the preceding ones, but which incorporate in their interior and with a sliding fit, a plate (27) provided with threaded holes (28) provided for first screws ( 29) mounted on the second supports (3).

Les cannelures longitudinales (25) font elles aussi partie de la variante représentée sur la figure 25, où elles font partie constitutive de moyens d'accouplement glissants qui sont complémentaires d'autres qui sont présents sur les deuxièmes supports (3), ces deuxièmes supports (3) sont réunis au bâti horizontal (5) et ce bâti horizontal (5) est fixé à l'extrémité d'un piston (31) qui fait partie d'un cylindre à fluide vertical (30).The longitudinal grooves (25) are also part of the variant shown in Figure 25, where they are part of sliding coupling means which are complementary to others which are present on the second supports (3), these second supports (3) are joined to the horizontal frame (5) and this horizontal frame (5) is attached to the end of a piston (31) which is part of a vertical fluid cylinder (30).

La figure 26 représente une solution où les cannelures longitudinales (25) ne sont pas nécessaires mais, pour obtenir le réglage continu et sélectivement variable en hauteur, il est prévu des crémaillères dentées verticales (32) correspondantes qui sont fixées aux montants (1) et dans lesquelles s'engrènent des pignons motorisés (33) qui sont fixés aux deuxièmes supports (3).FIG. 26 shows a solution where the longitudinal grooves (25) are not necessary but, in order to obtain the continuous and selectively variable adjustment in height, vertical toothed racks (32) are provided which are fixed to the uprights (1) and in which motorized gears (33) are meshes which are fixed to the second supports (3).

Les figures 27 et 28 représentent des solutions respectives pour permettre le réglage voulu, mais d'une façon discontinue, c'est-à-dire pas à pas. La variante représentée sur la figure 27 consiste en ce que les champs verticaux des montants (1), possèdent une pluralité de trous filetés avec une distribution appropriée (34), pour des deuxièmes vis respectives (35) qui sont montées sur les deuxièmes supports (3). De son côté, la figure 28 montre la variante consistant en ce que les champs verticaux des montants (1) présentent un rainurage (36) possédant un pas approprié entre les rainures consécutives, tandis que les deuxièmes supports (3) possèdent une paire de nervures (37) pouvant être accouplées dans des rainures correspondantes, consécutives ou non, dudit rainurage (36).Figures 27 and 28 show respective solutions to allow the desired adjustment, but in a discontinuous manner, that is to say step by step. The variant shown in FIG. 27 consists in that the vertical fields of the uprights (1) have a plurality of threaded holes with a suitable distribution (34), for respective second screws (35) which are mounted on the second supports ( 3). For its part, Figure 28 shows the variant consisting of the vertical fields of the uprights (1) have a groove (36) having a suitable pitch between the consecutive grooves, while the second supports (3) have a pair of ribs (37) which can be coupled in corresponding, consecutive grooves or no, said grooving (36).
