La présente invention a pour objet un poste de travail servant de bureau ou de table à dessin à au moins un utilisateur assis.The present invention relates to a work station serving as an office or a drawing table for at least one seated user.
On connaît par le brevet canadien CA 1 106 895 un bureau comportant un plan de travail transparent sous lequel est disposé un écran fixé à un cadre pouvant coulisser par rapport au plan de travail. Dans ce brevet, le plan de travail est fixé sur un bâti et ne peut être utilisé qu'en position horizontale. Par ailleurs, la zone d'affichage constituée par l'unique écran est de dimensions relativement faibles.We know from Canadian patent CA 1 106 895 a desk comprising a transparent work plan under which is disposed a screen fixed to a frame which can slide relative to the work plan. In this patent, the work surface is fixed to a frame and can only be used in a horizontal position. Furthermore, the display area constituted by the single screen is of relatively small dimensions.
On connaît par la demande internationale WO 85/03626 un poste de travail avec un écran unique disposé sous le plan de travail. L'écran est fixé au poste de travail par l'intermédiaire d'un dispositif lui permettant de glisser et de pivoter suivant plusieurs directions, ce qui rend ce dispositif relativement complexe. Par ailleurs, ce poste de travail ne permet la fixation que d'un unique écran, lequel est de taille relativement réduite, ce qui limite les possibilités d'affichage d'une image de grand format ou de plusieurs images simultanément. Ce poste de travail comporte en outre des pieds télescopiques.International application WO 85/03626 discloses a work station with a single screen arranged under the work plan. The screen is fixed to the workstation by means of a device allowing it to slide and pivot in several directions, which makes this device relatively complex.

On a représenté sur la figure 1 un poste de travail 1 conforme à l'invention, comportant une structure 2 supportée par un bâti 3.FIG. 1 shows a work station 1 according to the invention, comprising a structure 2 supported by a frame 3.
La structure 2 comporte un cadre 2a supportant quatre écrans 5 disposés selon une matrice rectangulaire 2x2. Dans l'exemple décrit, ces écrans 5 sont à tube cathodique.The structure 2 comprises a frame 2a supporting four screens 5 arranged in a rectangular 2x2 matrix. In the example described, these screens 5 are with cathode ray tube.
En variante, ils peuvent être du type à cristaux liquides, à plasma ou encore à microcapsules.Alternatively, they can be of the liquid crystal, plasma or microcapsule type.
Les écrans 5 définissent une zone d'affichage A de format A0 adaptée notamment à l'affichage de documents graphiques de grand format. Les écrans 5 sont fixés sur la structure 2 par l'intermédiaire de moyens de fixation, non représentés, permettant un démontage individuel de ceux-ci en cas de panne. Ils sont en outre recouverts par un vitrage plan 6, non amovible, présentant des propriétés mécaniques suffisantes vis-à-vis des chocs et des rayures, et qui sert également de plan de travail. La structure 2 comporte, le long de son bord longitudinal avant, une rigole 7 permettant à l'utilisateur d'y déposer des instruments de dessin ou d'écriture, par exemple. On peut encore, en plus de cette rigole 7 ou en remplacement de celle-ci, munir la structure 2 d'un ou plusieurs supports périphériques non représentés, permettant d'accueillir un ou plusieurs claviers et/ou de recevoir des touches de commande des écrans.The screens 5 define a display area A of format A0 suitable in particular for displaying large format graphic documents. The screens 5 are fixed to the structure 2 by means of fixing means, not shown, allowing individual disassembly of these in the event of a breakdown. They are also covered by a flat glazing 6, which is not removable, having sufficient mechanical properties with respect to impacts and scratches, and which also serves as a work surface. The structure 2 comprises, along its front longitudinal edge, a channel 7 allowing the user to place drawing or writing instruments there, for example. It is also possible, in addition to this channel 7 or as a replacement for this, to provide the structure 2 with one or more peripheral supports, not shown, making it possible to accommodate one or more keyboards and / or to receive keys for controlling the screens.
La structure 2 est reliée au bâti 3, dans l'exemple décrit, par l'intermédiaire d'un arbre 10 en deux parties, horizontal, et peut tourner autour d'un axe géométrique de rotation X. L'arbre 10 peut être creux de manière à loger des câbles de connexion, le cas échéant.The structure 2 is connected to the frame 3, in the example described, by means of a shaft 10 in two parts, horizontal, and can rotate around a geometric axis of rotation X. The shaft 10 can be hollow so as to accommodate connection cables, if necessary.
Le bâti 3 comporte deux éléments de support 12 (ou montants) chacun en forme de H, comprenant chacun deux pieds télescopiques 11, réglables en hauteur. Les pieds 11 peuvent être montés sur des roulettes permettant de déplacer facilement le poste de travail, ces pieds étant alors équipés d'un dispositif de blocage.The frame 3 comprises two support elements 12 (or uprights) each in the shape of an H, each comprising two telescopic legs 11, adjustable in height. The feet 11 can be mounted on casters allowing the work station to be easily moved, these feet then being fitted with a locking device.
Chaque élément de support 12 comporte en outre une traverse horizontale 15 reliant les pieds 11 et sur laquelle l'arbre 10 se raccorde par une articulation 18.Each support element 12 further comprises a horizontal crosspiece 15 connecting the feet 11 and on which the shaft 10 is connected by a hinge 18.
Un élément de verrouillage 19 agissant sur l'articulation 18 permet de verrouiller la structure 2 dans une position angulaire souhaitée, par exemple en position horizontale comme représenté sur la figure 1 ou en position inclinée, comme représenté sur la figure 2, voire verticale.A locking element 19 acting on the articulation 18 makes it possible to lock the structure 2 in a desired angular position, for example in a horizontal position as represented in FIG. 1 or in an inclined position, as shown in FIG. 2, even vertical.
Les réglages en hauteur et/ou de l'inclinaison de la structure 2 peuvent être effectués manuellement ou de manière motorisée. Le poste de travail peut comporter des éléments de blocage supplémentaires interdisant ou freinant la rotation de la structure 2 au-delà d'angles autorisés.The height and / or inclination of the structure 2 can be adjusted manually or in a motorized manner. The work station may include additional blocking elements preventing or braking the rotation of the structure 2 beyond authorized angles.
L'un des deux éléments de support 12, voire les deux, peut comporter au moins une étagère 16 permettant d'accueillir une unité centrale 17 servant d'appareil de contrôle des écrans, à laquelle sont reliés les écrans 5 par l'intermédiaire de câbles de connexion, non représentés.One of the two support elements 12, or even both, may comprise at least one shelf 16 making it possible to accommodate a central unit 17 serving as a screen control device, to which the screens 5 are connected by means of connection cables, not shown.
On peut bien entendu disposer sur l'étagère 16 tout autre élément périphérique tels qu'une imprimante, un scanner, des lecteurs de cédérom ou de DVD ou encore un onduleur.It is of course possible to have on the shelf 16 any other peripheral element such as a printer, a scanner, CD-ROM or DVD readers or even an inverter.
La carte mère de l'unité centrale et éventuellement d'autres cartes peuvent être placées dans des aménagements prévus dans la structure 2.The motherboard of the central unit and possibly other cards can be placed in the arrangements provided in structure 2.
L'unité centrale 17 est agencée pour permettre la gestion du contenu affiché sur chacun des écrans 5, et peut notamment commander la mise en marche d'une partie seulement des écrans 5 lorsque l'utilisateur ne souhaite utiliser qu'une partie de la zone d'affichage A. Lorsque plusieurs utilisateurs sont présents autour du poste de travail 1, l'unité centrale 17 peut commander l'apparition en différents endroits de la zone d'affichage A de plusieurs images, identiques ou non, orientées suivant des directions adaptées à chacun des utilisateurs. L'unité centrale 17 peut encore être agencée de manière à permettre une rotation de l'image affichée dans le plan du vitrage, afin d'orienter celle-ci suivant une direction souhaitée, adaptée à l'orientation de la structure 2.The central unit 17 is arranged to allow the management of the content displayed on each of the screens 5, and can in particular control the switching on of only part of the screens 5 when the user wishes to use only part of the area display A. When several users are present around the workstation 1, the central unit 17 can control the appearance in different places of the display area A of several images, identical or not, oriented in suitable directions to each of the users. The central unit 17 can also be arranged so as to allow rotation of the image displayed in the plane of the glazing, in order to orient the latter in a desired direction, adapted to the orientation of the structure 2.
La zone d'affichage A peut être agencée de manière à interagir avec un stylet électronique permettant à un utilisateur de modifier l'image affichée.The display area A can be arranged so as to interact with an electronic stylus allowing a user to modify the displayed image.
Le poste de travail 1 comporte en outre, dans l'exemple illustré, un traceur 20 fixé sur les éléments de support 12 suffisamment au-dessus et/ou en arrière de la structure 2 pour ne pas entraver sa rotation.The work station 1 also comprises, in the example illustrated, a tracer 20 fixed on the support elements 12 sufficiently above and / or behind the structure 2 so as not to impede its rotation.
On ne sort pas du cadre de la présente invention en remplaçant au moins l'un des écrans 5 par un dispositif de projection d'images 35, par exemple un vidéo projecteur, fixé à la structure 2, comme illustré à la figure 5.It is not going beyond the scope of the present invention to replace at least one of the screens 5 with an image projection device 35, for example a video projector, fixed to the structure 2, as illustrated in FIG. 5.
Le dispositif de projection 35 est apte à projeter une image sur la partie de la zone d'affichage A située au-dessus.The projection device 35 is capable of projecting an image on the part of the display area A situated above.
Le dispositif de projection 35 peut s'étendre sur une profondeur relativement importante sous le vitrage 6 mais l'utilisateur peut encore aisément placer ses jambes sous les trois écrans 5.The projection device 35 can extend over a relatively large depth under the glazing 6 but the user can still easily place his legs under the three screens 5.
On ne sort pas du cadre de la présente invention en n'utilisant qu'un seul écran.It is not beyond the scope of the present invention by using only one screen.
On a représenté sur la figure 3 un poste de travail 1 ' comportant une structure 2' fixée à un bâti 3 analogue à celui de l'exemple des figures 1 et 2.FIG. 3 shows a work station 1 ′ comprising a structure 2 ′ fixed to a frame 3 similar to that of the example in FIGS. 1 and 2.
La structure 2' comporte un caisson 25 et un panneau 26 refermant le caisson 25 et articulé sur le bord longitudinal arrière de ce dernier.The structure 2 ′ comprises a box 25 and a panel 26 closing the box 25 and articulated on the rear longitudinal edge of the latter.
Le panneau 26 supporte un vitrage 27 et un écran plat unique 5', de format A0, disposé sous celui-ci. Le panneau 26 peut être soulevé par l'utilisateur en le faisant pivoter vers l'arrière, comme représenté sur la figure 4, pour accéder à un compartiment intérieur 30. En variante, lorsque le vitrage est constitué de dalles, seule une dalle et l'écran associé pourraient être soulevés.The panel 26 supports a glazing 27 and a single flat screen 5 ′, of format A0, placed under it. The panel 26 can be lifted by the user by pivoting it backwards, as shown in FIG. 4, to access an interior compartment 30. As a variant, when the glazing consists of slabs, only one slab and the associated screen could be raised.
Bien entendu, l'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits.Of course, the invention is not limited to the exemplary embodiments which have just been described.
Les éléments de support 12 peuvent avoir une forme différente, notamment en A ou en T retourné, et être raccordés entre eux au niveau du sol.The support elements 12 can have a different shape, in particular in A or in inverted T, and be connected together at ground level.
On peut encore utiliser, si le poids de la structure le permet, un pied central unique, la structure étant par exemple reliée par une articulation de type rotule à ce pied. Dans ce cas, la structure peut pivoter d'un angle plus au moins important, voire proche de 90° par rapport à l'horizontale, dans un sens ou dans l'autre.We can still use, if the weight of the structure allows it, a central leg single, the structure being for example connected by a ball joint type to this foot. In this case, the structure can pivot by a more or less large angle, or even close to 90 ° relative to the horizontal, in one direction or the other.
Le poste de travail peut également servir de table à digitaliser ou de table lumineuse pour visualiser des transparents, par exemple. Il peut également servir de poste informatique comportant de nombreux équipements informatiques. Il peut encore comporter un ou plusieurs écrans tactiles.The workstation can also be used as a digitizing table or a light table for viewing transparencies, for example. It can also be used as a computer station with numerous computer equipment. It may also include one or more touch screens.
On peut encore munir le poste de travail d'un élément permettant de supprimer ou de limiter des reflets de lumière sur la zone d'affichage, par exemple une capote surplombant la zone d'affichage.It is also possible to provide the workstation with an element making it possible to suppress or limit reflections of light on the display area, for example a hood overhanging the display area.
La structure peut être reliée de manière non articulée au bâti, le pivotement s'effectuant en modifiant la hauteur des pieds du bâti.The structure can be connected in a non-articulated manner to the frame, the pivoting being effected by modifying the height of the legs of the frame.
Le bâti peut reposer sur une semelle ou un socle. The frame can rest on a sole or a base.
