The traction cable drive having a wind-up reel for a traction cable, said cable being fastened to a carriage (4'), is actuated by an electric motor. The cable is guided by means of deflection pulleys. The station permits an efficient arrangement of the workplace, direct access to peripheral devices and a rational economy of space.

Description

Höhenverstellbare PC-Arbeitsstation Height adjustable PC work station
Anwendungsgebiet der ErfindungField of application of the invention
Gegenstand vorliegender Erfindung ist eine in der Höhe verstellbare PC- Arbeitsstation mit den typischen Geräten, wie Zentraleinheit, Tastatur, Bildschirm und Drucker. Betroffen hierbei sind die Tischarbeitsfläche sowie die Ab- stellflächen für die beigeordneten Geräte.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.
Stand der Technik Derzeit üblich ist, dass ein PC-Arbeitsplatz aus einem Tisch mit davor positioniertem Bürostuhl besteht. Auf diesem Tisch befinden sich zumindest die Tastatur und eventuelle Arbeitsunterlagen. Häufig wird auch noch der Bildschirm auf dem Tisch abgestellt und - sofern der Platz ausreicht - der Drucker. Die übrigen Geräte, insbesondere die Zentraleinheit, stehen zumeist unter dem Tisch. Moderne Tische sind höhenverstellbar, wie auch die benutzten Bürodrehstühle, so dass wenigstens die ergonomisch richtige Arbeitshöhe für die auf einem solchen Tisch abgestellten, zumeist benutzten Geräte, einstellbar ist. An vielen PC-Arbeitsplätzen sind diverse Beistellmöbel anzutreffen, die als Ab- stellfläche für die Gerätekomponenten dienen. Diese Verteilung der Geräte in unterschiedlichen Winkeln zur Bedienperson und vor allem auf verschiedenen Höhen ist ineffektiv. Die Bedienperson muss sich häufig drehen und bücken um mit den verschiedenen Geräten zu arbeiten. Abgesehen vom positiven Effekt einer gewissen Bewegung während längerem Sitzens, ist es doch wünschenswert, den PC-Arbeitsplatz auch im Interesse einer übersichtlichen Büroan- Ordnung und effizienten Nutzung der Bürofläche rationeller zu gestalten.State of the art It is currently customary for 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. Various side furniture can be found at many PC workstations, which serve as a storage space for the device components. This distribution of the devices at different angles to the operator and especially at different heights is ineffective. The operator has to turn and bend frequently to work with the various devices. Apart from the positive effect of a certain movement while sitting for a long time, 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.
Aufgabe der ErfindungObject of the invention
Für den nichtprofessionellen Privatbereich in häuslicher Atmosphäre mit nur zeitweiliger Nutzung des PC und als Einzelplatz mag die geschilderte Situation völlig ausreichend sein. Im geschäftlichen Zweig, insbesondere in kleinerenFor the non-professional private area in a domestic atmosphere with only temporary use of the PC and as a single workstation, the situation described may be completely sufficient. In the business branch, especially in smaller ones
Büroräumen oder in Grossraumbüros mit vielen Angestellten, muss die derzeitige Arbeitsplatzgestaltung jedoch als unvollkommen bewertet werden. Der Erfindung liegt daher die Aufgabe zugrunde, einen höhenverstellbaren PC- Arbeitsplatz mit verbesserter Platzorganisation, direkterem Gerätezugriff und effizienterer Raumausnutzung zu schaffen.Offices or in open-plan offices with many employees, the however, current job design can 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.
Übersicht über die ErfindungOverview of the invention
Die essentiellen Erfindungsmerkmale lassen sich wie folgt zusammenfassen: Die höhenverstellbare PC-Arbeitsstation ruht auf einem Untergestell und weist beidseits des Untergestells je eine vertikale Schlittenführung auf, die aus zueinander beabstandeten Stangen besteht. Hierdurch ergeben sich zwischen den Stangen jeweils eine Schlittenbahn. In jeder Schlittenbahn ist ein, zwischen zwei Endlagen, auf- und abfahrbarer Schlitten geführt, wobei vorteilhaft beide Schlitten quer starr miteinander verbunden, so dann nur ein Zugseilantrieb erforderlich ist. Über den Zugseilantrieb wird das Verfahren der Schlitten bewirkt, die innerhalb der Arbeitsstation eine Tischplatte tragen und seitlich Konsolen zum Aufsetzen von Geräten - insbesondere Hardware, wie eine Zentraleinheit oder einen Drucker - aufweisen. Hierzu sind die Schlittenbahnen nach beiden Seiten offen.The essential features of the invention can be summarized as follows: 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. In each sledge run, a slide that can be moved up and down between two end positions is guided, advantageously both slides being connected rigidly to one another transversely, 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. For this purpose, the sled runs are open on both sides.
Die Stangen sind vorzugsweise aus Rundmaterial, insbesondere aus Rohren gebildet. Die vertikalen Schlittenbahnen liegen senkrecht zur Vertikalebene, die sich, in Blickrichtung eines vor der Arbeitsstation sitzenden Benutzers, zwischen beiden Schlittenführungen aufspannt. Die konfigurierte Tischplatte bietet in eine breitere Frontpartie und eine schmalere Hintergrundpartie kon- figuriert, den Vorteil einer grösseren körpernahen Arbeitsfläche mit z.B. einer Tastatur und Arbeitsunterlagen, während im Hintergrund ein Monitor stehen könnte.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 e.g. a keyboard and work documents, while a monitor could stand in the background.

Anhand der beiliegenden Zeichnungen erfolgt nachstehend die detaillierte Beschreibung eines Ausführungsbeispiels zur erfindungsgemässen höhenverstellbaren PC-Arbeitsstation.The accompanying drawings provide a detailed description of an exemplary embodiment of the height-adjustable PC workstation according to the invention.
Figuren 1 und 2Figures 1 and 2
Die PC-Arbeitsstation ruht auf einem auf den Boden aufsetzenden Untergestell 1 mit zwei beabstandeten ausladenden, zweiarmigen Beinen 10 und einer zwischen den Beinen eingefügten Traverse 11. Von den Seiten des Untergestells 1 erstreckt sich vertikal je eine vertikale Schlittenführung 2, die aus zuein- ander beabstandeten Rundstangen 20 besteht. Die beiden Rundstangen 20 sind so aufgestellt, dass sich dazwischen je eine in Querrichtung - der Erstreckung der Traverse 11 folgend - beidseits offene Schlittenbahn 21 ergibt. Zwischen den beiden Schlittenführungen 2, die über der Traverse 11 eine in Blickrichtung des vor der PC-Arbeitsstation sitzenden Benutzers eine Vertikal- ebene V aufspannen, ist eine horizontale Tischplatte 3 eingesetzt. Diese konfigurierte Tischplatte 3 besitzt eine verbreiterte Frontpartie 30, die sich vor der Vertikalebene V seitlich erweitert, und eine Hintergrundpartie 31 , welche sich zwischen den Schlittenführungen 2 verengend, hinter der Vertikalebene V erstreckt. Die Frontpartie 30 bietet somit eine breitere Arbeitsfläche für die Tastatur und zum Auslegen von Dokumenten, während die schmalere Hintergrundpartie 31 zum Aufstellen des Monitors vorgesehen ist. Oben werden die beiden Schlittenführungen 2 von einer Traverse 8 überbrückt und eine Abdeckung 9 verleiht der PC-Arbeitsstation einen geschlossenen Eindruck.The PC workstation rests on a base frame 1 resting on the floor with two spaced, projecting, two-armed legs 10 and a crossbar 11 inserted between the legs. A vertical slide guide 2 extends vertically from the sides of the base frame 1 and extends from one another spaced round rods 20 there. The two round bars 20 are set up in such a way that there is in each case a slide track 21 which is open on both sides in the transverse direction - following the extension of the crossmember 11. Between the two slide guides 2, which above the crossbar 11 a vertical in the viewing direction of the user sitting in front of the PC workstation plane V, a horizontal table top 3 is used. This configured table top 3 has a widened front part 30, which widens laterally in front of the vertical plane V, and a background part 31, which narrows between the slide guides 2, extends behind the vertical plane V. The front part 30 thus offers a wider working surface for the keyboard and for laying out documents, while the narrower background part 31 is provided for setting up the monitor. At the top, the two slide guides 2 are bridged by a traverse 8 and a cover 9 gives the PC workstation a closed impression.
In beide Schlittenbahnen 21 sind auf- und abfahrbare Schlitten 4,4' eingesetzt. An den Schlitten 4,4' sind eine gemeinsame nach innen weisende Innenkonsole 5 und jeweils nach aussen weisende Aussenkonsolen 6 befestigt, die Supporte für die innere Tischplatte 3 und für die aussen installierten Geräte bzw. Utensilien darstellen. Die Innenkonsole 5 bewirkt zugleich eine starre Verbindung zwischen den Schlitten 4,4". Alternativ zu einer einzigen Innenkonsole 5, welche die Tischplatte 3 trägt und beide Schlitten 4,4' verbindet, kann man auch zwei getrennte Innenkonsolen 5 vorsehen und die Verbindung der Schlitten 4,4' durch eine Traverse erreichen.Retractable and retractable slides 4, 4 'are inserted in both slide tracks 21. A common inward-facing inner console 5 and outward-facing outer consoles 6 are fastened to the slides 4, 4 'and represent supports for the inner table top 3 and for the devices or utensils installed on the outside. The inner console 5 also provides a rigid connection between the carriages 4, 4 ". As an alternative to a single inner console 5, which supports the table top 3 and connects both carriages 4, 4 ', two separate inner consoles 5 can also be provided and the connection of the carriages Reach 4.4 'by means of a traverse.
Mit dem simultanen Bewegen beider Schlitten 4,4' werden sowohl die Innenais auch die Aussenkonsolen 5,6 stets auf gleicher Höhe gehalten, so dass die Tischplatte 3 und auch die aussen aufgesetzten Objekte auf einer gemeinsamen Höhe positioniert sind.With the simultaneous movement of both carriages 4, 4 ', both the inner and outer consoles 5, 6 are always held at the same height, so that the table top 3 and also the objects placed on the outside are positioned at a common height.
Die Bewegung der Schlitten 4,4' geschieht über einen motorgetriebenen Zugseilantrieb 7 mit zugehöriger Schalteinheit 70 für die Befehle "AUF", "AB" und "STOP". In der oberen und der unteren Endlage wird der Schlittenantrieb 7 automatisch gestoppt. Der Zugseilantrieb 7 besteht neben dem nicht darge- stellten Elektromotor und der Schalteinheit 70 ferner aus einer Aufwickelrolle 71, die vom Motor angetrieben wird und das Auf- bzw. Abwickeln des Zugseils 72 betreibt. Geführt wird das Zugseil 72 von der Aufwickelrolle 71 beginnend, über die Umlenkrollen 73,74,75, welche in den Eckpunkten des Zugseilantriebes 7 angeordnet sind. Das erste Ende des Zugseils 72 ist an der Aufwickelrolle 71 befestigt, während das zweite Ende am zweiten Schlitten 4' in einem Fixpunkt 76 eingehängt ist, zu dem der volle Seilweg am ersten Schlitten 4 vorbei führt.The movement of the carriages 4, 4 'takes place via a motor-driven traction cable drive 7 with an associated switching unit 70 for the commands "UP", "DOWN" and "STOP". The carriage drive 7 is automatically stopped in the upper and lower end positions. In addition to the electric motor (not shown) and the switching unit 70, the pull rope drive 7 also consists of a winding roller 71 which is driven by the motor and the winding or unwinding of the pull rope 72 operates. The traction cable 72 is guided starting from the take-up reel 71, over the deflection rollers 73, 74, 75, which are arranged in the corner points of the traction cable drive 7. The first end of the pull rope 72 is fastened to the take-up reel 71, while the second end is hooked onto the second slide 4 ′ in a fixed point 76, to which the full rope path leads past the first slide 4.
Beim Befehl "AUF" dreht sich die Aufwickelrolle 71 in Aufwickelrichtung, so dass das Zugseil 72, sich sukzessive verkürzt, d.h. über die Umlenkrollen 73- 75 das Zugseil 72 einholt und hierbei den Schlitten 4' hochzieht, der mit dem anderen Schlitten 4 verbunden ist, wodurch beide Schlitten 4,4' simultan hochfahren. Ergeht der Befehl "AB", dreht sich die Aufwickelrolle 71 in Abwickelrichtung, worauf sich das Zugseil 72 und die Schlitten 4,4' simultan abwärtsfahren.With the command "OPEN" the take-up reel 71 rotates in the take-up direction so that the pull rope 72 is successively shortened, i.e. pulls the pull rope 72 over the deflection pulleys 73-75 and pulls up the carriage 4 ', which is connected to the other carriage 4, whereby both carriages 4, 4' move up simultaneously. If the command "AB" is issued, the take-up reel 71 rotates in the unwinding direction, whereupon the pull rope 72 and the slides 4, 4 'simultaneously descend.
Für die Rundstangen 20 kommt insbesondere Rohrmaterial in Betracht. In einer Einfachversion könnte die PC-Arbeitsstation auch mit einem manuell betätigten Zugseilantrieb, vorzugsweise mittels einer Kurbelanordnung, betrieben werden.Pipe material is particularly suitable for the round bars 20. In a simple version, the PC workstation could also be operated with a manually operated pull rope drive, preferably by means of a crank arrangement.

Zur reibungsarmen Führung der Schlitten 4,4' in der Schlittenbahn 21 zwischen den beiden Rundstangen 20, sind an den Schlitten 4,4' paarweise Führungsrollen 40 vorgesehen, die an den Rundstangen 20 ansetzen und Laufräder für die Schlitten 4,4' bilden. Vorzugsweise besitzen die Schlitten 4,4' ebene Seitenflächen 41 und eine Dicke, welche den Durchmesser der Rundstangen 20, überragt, so dass vorgenommene Anbauten nicht in Kontakt mit den Rundstangen 20 kommen können. Den Rundstangen 20 zugewandt besitzen die Schlitten 4,4" vorteilhaft beidseits vertikale Auskehlungen 42 in denen berührungsfrei die Rundstangen 20 stehen. For low-friction guidance of the carriages 4, 4 'in the carriage track 21 between the two round bars 20, pairs of guide rollers 40 are provided on the carriages 4, 4', which attach to the round bars 20 and form running wheels for the carriages 4, 4 '. The slides 4, 4 ′ preferably have flat side surfaces 41 and a thickness that projects beyond the diameter of the round bars 20, so that attachments made cannot come into contact with the round bars 20. Facing the round bars 20, the carriages 4, 4 "advantageously have vertical grooves 42 on both sides in which the round bars 20 are free of contact.
