Definitions

  • the present invention relates to a height-adjustable PC workstation with the typical devices such as a central unit, keyboard, screen and printer. This affects the table work surface and the storage areas for the associated devices.
  • a PC workstation To consist of a table with an office chair positioned in front of it. At least the keyboard and any work documents are on this table. Often the screen is placed on the table and - if there is enough space - the printer. The other devices, especially the central unit, are usually under the table. Modern tables are height adjustable, as are the office swivel chairs used, so that at least the ergonomically correct working height can be set for the devices used on such a table, which are mostly used. At many PC workstations, various side furniture can be found, which serve as a storage area for the device components. This distribution of the devices at different angles to the operator and above all at different heights is ineffective. The operator has to turn and bend frequently to work with the various devices. In addition to the positive effect of a certain movement during long sitting, it is desirable to make the PC workstation more efficient, also in the interest of a clear office arrangement and efficient use of the office space.
  • FR 2 235 871 A1 discloses a frame consisting of two mutually spaced-apart pairs of angular vertical supports, each with an intermediate slideway and a slide guided therein.
  • the vertical supports In the vertical supports there are vertical grooves that run through to the front and back, so that one of the two slides can protrude through the vertical supports.
  • Longitudinal beams are placed over the crossbeams on both sides of the frame, which serve to hold panels that are height-adjustable. form adjustable storage and / or work surfaces.
  • the sleds are powered by a cable.
  • the frame structure with a large space requirement is very solid and only one storage and / or work surface is created. Assembly and service work on the frame are likely to be relatively complex.
  • the situation described may be completely sufficient.
  • the current workplace design has to be assessed as imperfect.
  • the invention is therefore based on the object of creating a height-adjustable PC workstation with improved space organization, more direct device access and more efficient use of space.
  • the task is to further develop the frame described above as known, namely the slide and the slide guide with the aim of creating several differently usable areas and to facilitate assembly and service.
  • the height-adjustable PC workstation rests on a base frame and has a vertical slide guide on both sides of the base frame, which consists of rods that are spaced apart. This results in a sled run between the bars.
  • a slide that can be moved up and down between two end positions is guided, advantageously both slides being rigidly connected to one another, so that only one pull cable drive is required.
  • the traction cable drive is used to move the slides, which carry a table top within the workstation and have consoles on the side for attaching devices - in particular hardware, such as a central unit or a printer.
  • the sled runs are open on both sides.
  • the rods are preferably formed from round material, in particular from tubes.
  • the vertical slide tracks are perpendicular to the vertical plane, which, viewed in the direction of view of a user sitting in front of the workstation, spans between the two slide guides.
  • the configured table top configured in a wider front section and a narrower background section, offers the advantage of a larger body-like work surface with a keyboard and working documents, while a monitor could be in the background.
  • An electric motor is preferably used to drive the pull rope drive, which rotates a winding roller on which a first end of the pull rope is fastened.
  • the second end of the pull rope is guided over deflection rollers from the winding roller past a slide to the second slide at a fixed point.
  • the slides travel along the round bars on guide rollers arranged in pairs. It is particularly advantageous to make the side surfaces of the slides flat and to provide the thickness of the round rods so that they are outstanding on both sides.
  • a spindle drive with a threaded spindle arranged vertically in the slide guide is proposed on both sides of the frame.
  • the drive motor inserted in the slide, includes the spindle, can be removed from the two-part slide and moves the slide up and down on the fixed spindle.
  • the upper spindle end is held in a fixed point positioned in the upper crossbeam.

Abstract

L'invention concerne un meuble multimédia réglable en hauteur présentant, de chaque côté du bâti (1), une coulisse verticale (2) formée de deux barres rondes (20) espacées. On obtient ainsi entre les barres rondes (20) respectivement une glissière (21) ouverte des deux côtés. Des coulisseaux (4, 4'), guidés verticalement dans les glissières (21), sont déplacés par un mécanisme d'entraînement à câble de traction ou à broche (7, 7'). A l'intérieur du meuble multimédia, les coulisseaux (4, 4') supportent un plateau (3) et, à l'extérieur du meuble multimédia, ils supportent des consoles (6) destinées à des appareils ou accessoires. Le plateau (3), saillant à proximité du corps pour constituer le plan de travail et plus étroit entre les coulisses (2), permet de recevoir au fond l'écran et de placer devant soi, par exemple, un clavier et des documents. Le mécanisme à câble de traction doté d'une poulie d'enroulement destinée au câble de traction, lequel est fixé à un coulisseau (4'), est actionné par un moteur électrique. Le câble est guidé à l'aide de poulies de guidage. Dans le cas du mécanisme à broche (7'), le moteur d'entraînement (71') est intégré au coulisseau (4, 4') de façon amovible. Ce meuble multimédia constitue un poste de travail de conception efficace. Il permet un accès direct aux appareils, même aux périphériques et une utilisation rationnelle de l'espace.
