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 les 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" to the work surface, such as electrical energy, fluids of all kinds, as well as for removing residues 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 difficile son utilisation et son nettoyage.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 the power supply wires of the 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 the accidental hanging of the wires placed on the front of the table, which can 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, the fact of having water, gas taps, sockets and built-in 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 concealed bowl 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 some 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 of '' a tap or a power supply.

La table suivant l'invention est exempte de tous ces inconvénients.The table according to the invention is free from all these drawbacks.

Elle est caractérisée en ce qu'elle présente une face constituant, lors de l'utilisation la face frontale, un canal comportant une paroi arrière sur laquelle vient s'appliquer le plan de travail et qui est munie de perforations pouvant recevoir des utilités telles que prises électriques, robinetteries et arrivées de fluides, une partie parallèle au plan de travail pouvant servir de réceptacle pour les tuyaux et câbles reliant entre eux les appareils utilisés sur la table et leurs accessoires, et une paroi avant protégeant la paroi arrière du canal.It is characterized in that it has a face constituting, when in use the front face, a channel comprising a rear wall on which the work surface is applied and which is provided with perforations capable of receiving utilities such as electrical outlets, fittings and fluids, a part parallel to the work surface that can serve as a receptacle for pipes and cables connecting together the devices used on the table and their accessories, and a front wall protecting the rear wall of the channel.

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 nonlimiting 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 présente une face constituant, lors de son utilisation, sa face frontale, un canal 1 comportant une paroi arriére la. Dans l'exemple traité, le canal 1 est en forme d'U, à fond plat. La paroi verticale arrière la du canal 1 sur laquelle vient s'appliquer le plan de travail 2, est munie de perforations 3 pour recevoir, par exemple, 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 can be seen in particular in FIG. 1, the table has a face constituting, when in use, its front face, a channel 1 comprising a rear wall 1a. In the example treated, channel 1 is U-shaped, with a flat bottom. The rear vertical wall 1a of the channel 1 on which the work surface 2 is applied, is provided with perforations 3 for receiving, for example, on plates fitting into these perforations, taps 4, electrical sockets 5 and various accessories, connecting to energy distribution plies 6, placed, for example under the work surface 2.

La partie du canal 1 parallèle au plan de travail 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 part of channel 1 parallel to the work surface 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 avant 1b du canal 1 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 front part 1b of the channel 1 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.

Le plan de travail 2 qui peut être monolithique ou en plusieurs éléments juxtaposés, est, suivant l'invention, monté de façon amovible, 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.The worktop 2 which can be monolithic or in several juxtaposed elements, is, according to the invention, removably mounted, advantageously pivotally, as shown in Figure 1. When it is in several elements, as in example treated, it is possible to provide, at the junction of the elements, grooves or rebates 11, in which the cables and other pipes coming from the rear of the devices and passing to the manifold 1 can pass.

Sous le plan de travail 2 est prévu un second canal 10 adjacent au premier canal 1 et dont la paroi verticale avant est constituée par la paroi verticale arrière la du premier canal 1.Under the work surface 2 is provided a second channel 10 adjacent to the first channel 1 and the front vertical wall of which is constituted by the rear vertical wall 1a of the first channel 1.

Dans ce second canal aboutissent les câbles et tuyaux en provenance de l'arrière des appareils disposés sur la table, afin d'y être branchés sur les utilités disposées dans le premier canal 1, ou être conduits par celui-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.In this second channel lead the cables and pipes coming from the back of the devices arranged on the table, in order to be connected to the utilities arranged in the first channel 1, or to be led by it to another location on the table where there is, for example, another device requiring the establishment of a connection with the first device.

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 du canal 1, et, de toute façon, sur un bord tombé 1c que présente le canal 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 channel 1, and, in any case , on a fallen edge 1c presented by the channel 1.

Les extrémités des premier et second canaux sont ouvertes, ce qui permet leur continuité dans le cas du placement de plusieurs tables semblables, bout à bout pour constituer des longueurs déterminées par une pluralité de tables.The ends of the first and second channels are open, which allows their continuity in the case of the placement of several similar tables, end to end to form lengths determined by a plurality of tables.

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 aceaux 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 et 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 allows, in general, to completely disengage the work surface from any cables or connecting pipes, which gives connection cables, which gives free and instant access to the utilities intended to be connected to the devices. located on the table, at fittings, sockets and drainage basins, the surface of the work surface is also completely free from the placement of these various means and organs.

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 montage 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 and pivoting worktop, thus making it easy to assemble by a user in the standing working position.

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.
