Abstract

A table, notably a laboratory table, characterized in that it is provided, in its frontal face, with a collector-distributor made of a channel arranged in such a manner as to support the utilities such as the electric plugs, water fittings and fluid feeding pipes, disposal basins for equipping the table, as well as to receive and lead the cables and pipes likely to connect the apparatuses used on the table and their accessories to each others.

Description

La présente invention concerne une table, notamment de laboratoire, perfectionnée.The present invention relates to an improved table, in particular a laboratory table.

La condition essentielle que doit satisfaire une table, notamment de laboratoire, est d'offrir un plan de travail dont la surface est aussi dégagée que possible des saillies et obstacles qui peuvent résulter de la présence d'organes et de moyens, tels que prises, robinets, cuvettes et autres, nécessaires aussi bien pour amener au plan de travail les diverses "utilités", telles qu'énergie électrique, fluides de toutes sortes, que pour évacuer le§ résidus des travaux effectués sur la table.The essential condition which a table, in particular a laboratory table, must satisfy is to offer a work surface whose surface is as free as possible from the projections and obstacles which may result from the presence of organs and means, such as sockets, taps, bowls and the like, necessary both for bringing the various "utilities", such as electrical energy, fluids of all kinds, to the worktop, as well as for removing the residue from work carried out on the table.

Cette condition n'est guère satisfaite par les tables connues, dans lesquelles les utilités dont il vient d'être question, toujours placées à l'arrière du plateau de la table, l'encombrent au détriment des appareils qu'elle reçoit sur son plan de travail, ces mêmes appareils nuisant à l'accessibilité, pour utilisation ou réglage, des utilités dont s'agit.This condition is hardly satisfied by the known tables, in which the utilities just mentioned, still placed at the back of the table top, clutter it to the detriment of the devices it receives on its plane of work, these same devices impairing the accessibility, for use or adjustment, of the utilities in question.

Il est certes connu, pour remédier partiellement à ces défauts, de disposer certains moyens ou organes, tels que prises de courant électrique, sur la retombée avant de la table, mais alors des fils d'alimentation .des appareils pendent sur la face avant de la table, pour ensuite repartir vers l'arrière des appareils où leur branchement s'effectue habituellement. Ce placement frontal des prises électriques a pour inconvénient d'occasionner l'accrochage accidentel des fils placés sur l'avant de la table, ce qui peut entraîner la chute des appareils et de leurs accessoires. Ce placement a aussi pour inconvénient de faire courir sur le plan de travail des fils nécessaires au raccordement des.appareils, ce qui encombre la surface de travail et rend son utilisation et son nettoyage difficiles.It is certainly known, to partially remedy these faults, to have certain means or organs, such as electrical outlets, on the front drop of the table, but then power wires. Devices hang on the front face of the table, and then set off towards the rear of the devices where they are usually connected. This front placement of electrical outlets has the disadvantage of causing accidental hanging of the wires placed on the front from the table, which could cause the devices and their accessories to fall. This placement also has the disadvantage of running on the work surface of the wires necessary for the connection of the devices, which clutters the work surface and makes its use and cleaning difficult.

Par ailleurs, le fait de disposer des robinetteries d'eau, de gaz, des prises de courant et des cuvettes encastrées sur un plan de travail rend celui-ci inamovible et ne permet pas de le lever pour accéder aisément aux tuyauteries principales d'alimentation, pour effectuer toutes opérations d'entretien, de dépannage, ainsi que des raccordements complémentaires.In addition, having water, gas taps, sockets and flush-mounted bowls on a work surface makes it irremovable and does not allow it to be lifted for easy access to the main supply pipes. , to carry out all maintenance and troubleshooting operations, as well as additional connections.

Dans ces conditions, la transformation en vue de l'adaptation de la table à d'autres utilisations que celle prévue à l'origine est extrêmement difficile, comme, par exemple, la création d'un poste d'eau constitué d'une cuvette encastrée et de son évacuation, ou du montage d'une robinetterie supplémentaire.Under these conditions, the transformation with a view to adapting the table to other uses than that originally planned is extremely difficult, such as, for example, the creation of a water station consisting of a bowl concealed and its evacuation, or the fitting of an additional tap.

Le principal défaut des tables de conception traditionnelle vient, en définitive, du positionnement des utilités sur la partie arrière de la table, ce qui rend difficile leur mise en oeuvre quand, comme dans la majorité des cas, les appareils placés devant elles les masquent au point qu'elles ne sont plus accessibles. Dans certains cas d'appareils ou de montages larges et hauts, il est pratiquement impossible d'accéder aux utilités, ce qui est parfois un facteur d'accident, dont la victime est l'utilisateur, quand il faut intervenir avec rapidité sur la coupure d'une robinetterie ou d'une alimentation électrique.The main defect of tables of traditional design comes, ultimately, from the positioning of utilities on the back of the table, which makes their implementation difficult when, as in most cases, the devices placed in front of them hide them point that they are no longer accessible. In certain cases of wide and high devices or fixtures, it is practically impossible to access the utilities, which is sometimes a factor of accident, of which the victim is the user, when it is necessary to intervene quickly on the cut a tap or a power supply.

La présente invention élimine tous ces inconvénients.The present invention eliminates all of these drawbacks.

Elle consiste essentiellement à faire comporter à la table, sur sa face frontale, un collecteur-distributeur constitué par une goulotte technique agencée de façon à recevoir toutes les utilités, telles que prises électriques, robinetteries de gaz et arrivées d'eau, cuvettes d'évacuation d'eau, destinées à équiper la table, et également agencée, suivant l'invention, pour recevoir et conduire les câbles et tuyaux qui relient entre eux les appareils et leurs accessoires.It essentially consists in making the table have, on its front face, a collector-distributor constituted by a technical chute arranged so as to receive all the utilities, such as electrical outlets, gas taps and water inlets, bowls. water evacuation, intended to equip the table, and also arranged, according to the invention, to receive and conduct cables and pipes which interconnect the devices and their accessories.

On a décrit ci-après, à titre d'exemple non limitatif, une forme de réalisation de l'invention, en référence aux dessins annexés, sur lesquels

  • - la Figure 1 est une vue en perspective ;
  • - la Figure 2 est une vue partielle, en coupe transversale, d'une table de laboratoire suivant l'invention ; et,
  • - les Figures 3 à 5 sont des vues partielles, en perspective, montrant l'adaptation à la table de certains accessoires.
An embodiment of the invention has been described below, by way of non-limiting example, with reference to the appended drawings, in which
  • - Figure 1 is a perspective view;
  • - Figure 2 is a partial view, in cross section, of a laboratory table according to the invention; and,
  • - Figures 3 to 5 are partial perspective views showing the adaptation of certain accessories to the table.

Comme on le voit notamment sur la Figure 1, la table comporte, suivant l'invention, prévue sur sa face frontale, une goulotte 1, formant collecteur-distributeur. Dans l'exemple traité, la goulotte est en forme d'U, à fond plat. La paroi verticale arrière la, sur laquelle vient s'appliquer le plan de travail 2, est munie de perforations 3 pour recevoir, sur des platines s'emboîtant dans ces perforations, des robinetteries 4, des prises électriques 5 et des accessoires divers, se raccordant sur des nappes 6 de distribution d'énergies, placées, par exemple, sous le plan de travail 2.As seen in particular in Figure 1, the table comprises, according to the invention, provided on its front face, a chute 1, forming a collector-distributor. In the example treated, the chute is U-shaped, with a flat bottom. The rear vertical wall 1a, on which the work surface 2 is applied, is provided with perforations 3 for receiving, on plates fitting into these perforations, taps 4, electrical sockets 5 and various accessories, connecting on 6 energy distribution plies, placed, for example, under the worktop 2.

La partie horizontale de la goulotte est utilisée pour conduire et porter les câbles et tuyaux, tels que 7, qui relient les appareils, tels que 8, et leurs accessoires, tels que 9, entre eux.The horizontal part of the chute is used to conduct and carry cables and pipes, such as 7, which connect the devices, such as 8, and their accessories, such as 9, to each other.

La partie verticale et frontale lb de la goulotte protège les câbles et les manoeuvres des robinetteries de fluides, tels que gaz et eau, de tout accrochage accidentel de la part de l'utilisateur, au cours de ses déplacements ou de ses mouvements dans le laboratoire.The vertical and front part l b of the trunking protects the cables and the maneuvers of the taps from fluids, such as gas and water, from any accidental hanging on the part of the user, during his movements or his movements in the laboratory.

La goulotte 1, servant de collecteur-distributeur, est avantageusement en communication avec un vide technique 10, prévu sous le plan de travail, vide dans lequel les câbles et tuyaux en provenance de l'arrière des appareils disposés sur la table aboutissent, afin d'y être branchés sur les utilités disposées dans la goulotte, ou être conduits par celle-ci à un autre emplacement de la table où se trouve, par exemple, un autre appareil nécessitant l'établissement d'une liaison avec le premier appareil.The chute 1, serving as a collector-distributor, is advantageously in communication with a technical vacuum 10, provided under the work plan vail, void in which the cables and hoses coming from the back of the apparatuses arranged on the table lead, in order to be connected there on utilities arranged in the chute, or to be led by this one to another location of the table where, for example, there is another device requiring the establishment of a connection with the first device.

Quant au plan de travail 2, qui peut être monolithique ou en plusieurs éléments juxtaposés, les dispositions adoptées suivant l'invention permettent de le monter de façon amovible, et avantageusement à pivotement, comme le montre la Figure 1. Lorsqu'il est en plusieurs éléments, comme dans l'exemple traité, il est possible de prévoir, à la jonction des éléments, des rainures ou feuillures 11, dans lesquelles peuvent passer les câbles et autres tuyaux provenant de l'arrière des appareils et aboutissant au collecteur 1.As for the work plan 2, which can be monolithic or in several juxtaposed elements, the arrangements adopted according to the invention make it possible to mount it in a removable manner, and advantageously with pivoting, as shown in Figure 1. When it is in several elements, as in the example treated, it is possible to provide, at the junction of the elements, grooves or rebates 11, through which the cables and other pipes coming from the rear of the apparatuses and leading to the collector 1 can pass.

Grâce aux dispositions adoptées suivant l'invention, il est facile, comme le montrent les Figures 3 à 5, d'adapter à la table, et en un point quelconque de cette dernière, les accessoires les plus divers, tels que tablettes à écrire 12 (Figure 4), porte-éprouvettes 13 et mini- cuvette 14 (Figure 3), écran de protection 15 (Figure 5), prenant appui soit sur le plan de travail, soit sur le fond de la goulotte-collecteur, et, de toute façon, sur un bord tombé lc que présente la goulotte 1.Thanks to the arrangements adopted according to the invention, it is easy, as shown in Figures 3 to 5, to adapt to the table, and at any point of the latter, the most diverse accessories, such as writing tablets 12 (Figure 4), test-tube holder 13 and mini-bowl 14 (Figure 3), protective screen 15 (Figure 5), supported either on the work surface or on the bottom of the collecting trough, and anyway, on a fallen edge l c presented by the chute 1.

On voit, de ce qui précède, que l'invention présente d'importants et nombreux avantages.It can be seen from the above that the invention has important and numerous advantages.

Elle permet d'abord, d'une façon générale, de dégager totalement le plan de travail de tous câbles ou tuyaux de liaison, ce qui donne accès libre et instantané aux utilités destinées à être raccordées sur les appareils situés sur la table, aux robinetteries, prises de courant at cuvettes d'évacuation, la surface du plan de travail étant en outre totalement libérée du placement de ces divers moyens et organes.First of all, it generally clears the work surface of all cables or connecting pipes, which gives free and instant access to utilities intended to be connected to devices located on the table, to fittings , sockets and drainage basins, the surface of the work surface also being completely free from the placement of these various means and members.

Par ailleurs, l'invention se prête particulièrement bien à la disposition des tuyauteries principales en nappes horizontales, situées sous le plan de travail amovible et pivotant, rendant ainsi aisé leur mon- w tage par un utilisateur en position de travail debout.Furthermore, the invention lends itself particularly well to the provision of main pipes in horizontal plies, located under the removable worktop and pivoting, thus making easy their MON w floor by a standing working position in user.

Egalement, l'invention permet l'accès facile, par levage du plan de travail, aux tuyauteries principales, pour effectuer tous travaux d'entretien, de raccordements supplémentaires, ou autres.Also, the invention allows easy access, by lifting the worktop, to the main pipes, to carry out any maintenance work, additional connections, or other.

L'invention permet la fabrication standard et industrialisée de plans de travail libérés de tous percements pour robinetterie ou placement de cuvettes d'évacuation, d'où la possibilité d'une fabrication industrielle de modules standard de tables préfabriquées recevant leur équipement à la demande, répondant ainsi à l'exigence de souplesse d'installation, d'adaptation et de reconversion qu'exigent les laboratoires modernes, en particulier en ce qui concerne le placement, le déplacement des modules de tables et la création d'utilités de toute nature, robinetteries, cuvettes d'évacuation, prises de courant, etc.The invention allows standard and industrialized manufacture of worktops free from any holes for taps or placement of drainage bowls, hence the possibility of industrial manufacture of standard modules of prefabricated tables receiving their equipment on demand, thus meeting the requirement of flexibility of installation, adaptation and reconversion that modern laboratories demand, in particular with regard to the placement, the displacement of table modules and the creation of utilities of all kinds, fittings, drainage basins, sockets, etc.

Enfin, l'invention se prête particulièrement bien à l'organisation par l'utilisateur de son poste de travail, en ce qui concerne le transport des câbles et tuyaux reliant les appareils entre eux, et à la satisfaction des exigences de sécurité pour l'accès usuel et pour l'intervention d'urgence aux robinets d'arrêt et aux coupures des alimentations électriques.Finally, the invention lends itself particularly well to the organization by the user of his work station, with regard to the transport of cables and pipes connecting the devices together, and to the satisfaction of safety requirements for the usual and emergency access to shut-off valves and to power cutouts.
