Description

Die Erfindung betrifft einen höhenverstellbaren Tisch für Bildschirmarbeitsplätze mit einem Tischgestell mit Tischsäulen aus aufstehenden Säulenunterteilen und damit teleskopierenden Säulenoberteilen und mit die Säulenunterteile verbindender Traverse mit Höhenstellvorrichtungen für die teleskopierenden, einerseits eine Tastaturplatte, andererseits eine unabhängig von der Tastaturplatte verstellbare Bildschirmplatte tragenden Säulenoberteile, wobei das Tischgestell für die Tastaturplatte und die Bildschirmplatte jeweils eigene Säulenunterteile, Säulenoberteile und eine eigene Höhenverstellvorrichtung aus in vertikaler Position an den Säulenunterteilen und der Traverse gelagerten Spindeln mit Spindelmuttern aufweist, die einerseits mittels durch Schlitzführungen in den Säulenunterteilen hindurchgreifender Verbindungsstege mit den teleskopierenden Säulenoberteilen, andererseits mittels sich über die Länge der Traverse erstreckender Verbindungswellen miteinander verbunden sind, ferner mit auf der Vorderseite des Tisches der rechten Tischsäule und der linken Tischsäule zugeordneten Betätigungsvorrichtungen mit zu den Verbindungswellen orthogonalen Antriebswellen für die Spindeln einerseits der Tastaturplatte und andererseits der Bildschirmplatte.The invention relates to a height-adjustable table for VDU workstations with a table frame with table columns made of standing column bases and thus telescoping column top parts and with the column bottom parts crossbar with height adjustment devices for the telescopic, on the one hand a keyboard plate, and on the other hand, an independent of the keyboard plate adjustable tabletop carrying column tops, the table frame for the keyboard plate and the screen plate each have their own pillar lower parts, upper pillar parts and their own height adjustment device consisting of spindles with spindle nuts mounted in a vertical position on the pillar lower parts and the traverse, which on the one hand by means of connecting webs with slot telescoping through the pillar lower parts with the telescopic pillar upper parts, and on the other hand, over the length of the traverse extending connecting shafts are connected to each other, also with on the front of the table of the right table column and the left table column actuators associated with drive shafts orthogonal to the connecting shafts for the spindles on the one hand the keyboard plate and on the other hand the display plate.

Es ist ein höhenverstellbarer Tisch bekannt, bei welchem die Antriebswellen für die beiden getrennt zu betätigenden Höhenverstellvorrichtungen einerseits der rechten und andererseits der linken Tischsäule zugeordnet sind und endseitig Betätigungsknöpfe aufweisen. Bei dieser bekannten Ausführungsform liegen die Antriebswellen jedoch sichtbar ausserhalb der Tischsäulen. Das stört nicht nur in ästhetischer Hinsicht, sondern verlangt ausserdem zusätzliche konstruktive Massnahmen zur Lagerung der Antriebswellen and den im übrigen getrennten Traversen für die einerseits der Tastaturplatte, andererseits der Bildschirmplatte zugeordneten Tischsäulen.A height-adjustable table is known in which the drive shafts for the two height adjustment devices to be operated separately are assigned to the right and left table columns on the one hand and have actuating buttons on the end. In this known embodiment, however, the drive shafts are visibly outside the table columns. This is not only aesthetically disturbing, but also requires additional structural measures for mounting the drive shafts and the separate crossbeams for the table columns assigned to the keyboard plate on the one hand and the display plate on the other.

Ausserdem kennt man einen höhenverstellbaren Tisch, bei welchem zur Höhenverstellung der Tischplatte eine Antriebswelle vorgesehen ist, welche beide Säulenunterteile und Säulenoberteile für die Tischplatte durchdringt und zugleich die Funktion einer Verbindungswelle in einer Traverse für beide Tischbeine erfüllt. Die durchdrungenen Säulenoberteile weisen vertikale Langlöcher von zumindest Hublänge für die sie durchdringende Antriebswelle auf (vgl. CH-A 180 358). - Die Probleme um eine funktionsgerechte und in ästhetischer Hinsicht befriedigende Anordnung von Antriebswellen, welche im wesentlichen orthogonal zu denVerbindungsweIlen in der Traverse verlaufen, sind durch diese bekannten Massnahmen nicht massgebend beeinflusst worden.In addition, a height-adjustable table is known, in which a drive shaft is provided for height adjustment of the table top, which penetrates both lower and upper column parts for the table top and at the same time fulfills the function of a connecting shaft in a traverse for both table legs. The penetrated column tops have vertical elongated holes of at least stroke length for the drive shaft penetrating them (cf. CH-A 180 358). - The problems of a functionally appropriate and aesthetically satisfactory arrangement of drive shafts, which are essentially orthogonal to the connecting shafts in the traverse, have not been significantly influenced by these known measures.

Der Erfindung liegt die Aufgabe zugrunde, einen höhenverstellbaren Tisch für Bildschirmarbeitsplätze der eingangs beschriebenen Art zu schaffen, bei dem die Antribswellen für die Höhenverstellvorrichtungen gleichsam unsichtbar im Tischgestell untergebracht und einfach gelagert sind.The invention has for its object to provide a height-adjustable table for VDU workstations of the type described above, in which the anvils for the height adjustment devices are invisibly housed in the table frame and stored easily.

Diese Aufgabe löst die Erfindung bei einem gattungsgemässen höhenverstellbaren Tisch dadurch, dass die Antriebswellen jeweils das Säulenunterteil und das Säulenoberteil für die Tastaturplatte durchdringen, und dass die durchdrungenen Säulenoberteile vertikale Langlöcher von zumindest Hublänge für die sie durchdringenden Antriebswellen aufweisen. - Diese Massnahmen der Erfindung haben zur Folge, dass das Tischgestell der Antriebswellen herangezogen werden kann, und zwar derart, dass nur noch die zwangsläufig aussenliegenden Betätigungsvorrichtungen für diese Antriebswellen unterhalb der Tischplatte auf der Vorderseite des Tisches sichtbar sind. Im Rahmen der Erfindung besteht grundsätzlich auch die Möglichkeit, die Antribswellen so anzuordnen, dass sie jeweils das Säulenunterteil und das Säulenoberteil für die Bildschirmplatte durchdringen, sich folglich die Betätigungsvorrichtungen für die Antriebswellen auf der Rückseite des erfindungsgemässen Tisches befinden. Stets kann die Betätigung der Höhenverstellvorrichtungen von der Vorderseite bzw. Rückseite des Tisches erfolgen.This object is achieved by the invention in the case of a generic height-adjustable table in that the drive shafts penetrate the column lower part and the column upper part for the keyboard plate, and that the penetrated column upper parts have vertical elongated holes of at least stroke length for the drive shafts penetrating them. - These measures of the invention have the result that the table frame of the drive shafts can be used in such a way that only the inevitably external actuating devices for these drive shafts are visible below the table top on the front of the table. Within the scope of the invention there is in principle also the possibility of arranging the anvil shafts in such a way that they respectively penetrate the lower column part and the upper column part for the screen plate, and consequently the actuating devices for the drive shafts are located on the rear of the table according to the invention. The height adjustment devices can always be operated from the front or rear of the table.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind im folgenden aufgeführt. So empfiehlt die Erfindung, dass die Antriebswellen in den Säulenunterteilen und/oder in der sämtliche Säulenunterteile verbindenden Traverse gelagert sind und dazu die Traverse Lagerwangen für die Antriebswellen aufweist. Insoweit wird eine vollständige Abdeckung auch jener Antriebswelle erreicht, welche auf die hintere Höhenverstellvorrichtung für die Bildschirmplatte arbeitet. Vorzugsweise sind innerhalb der Traverse auf den Antriebswellen und auf den oberen Enden der Spindeln für jeweils die Höhenverstellung der Tastaturplatte und der Bildschirmplatte kämmende Kegelräder oder Schnecken und Schneckenräder angeordnet. Darüber hinaus können über die Länge der Traverse Verbindungswellen mit endseitigen Kegelrädern für die Spindeln der Höhenverstellvorrichtungen vorgesehen sein, so dass verkantungsfreie Höhenverstellung der Säulenoberteile in den Säulenunterteilen erfolgt, obwohl der Antrieb einseitig, nämlich mittels der einerseits in der rechten Tischsäule und andererseits in der linken Tischsäule gelagerten Antribswellen erfolgt. Über die Verbindungswellen wird ferner eine beidseitig synchrone Höhenverstellung erreicht. - Auf den über die Säulenunterteile vorstehenden Enden der Antriebswellen können auswechselbare Handhabungen wie Betätigungsknöpfe, Handkurbeln, Handräder oder dergleichen befestigt sein. Vorzugsweise weisen die vorstehenden Enden der Antriebswellen Steckvorrichtungen zum Aufstecken von Handkurbeln auf, so dass mit einer einzigen Handkurbel beide Antriebswellen wechselweise betätigt werden können.Further advantageous embodiments of the invention are listed below. The invention thus recommends that the drive shafts are mounted in the lower pillar parts and / or in the crossbar connecting all lower pillar parts and for this purpose the crossbar has bearing cheeks for the drive shafts. In this respect, complete coverage is also achieved for that drive shaft which works on the rear height adjustment device for the screen plate. Preferably, bevel gears or worms and worm gears meshing within the crossbeam are arranged on the drive shafts and on the upper ends of the spindles for the height adjustment of the keyboard plate and the screen plate. In addition, connecting shafts with end bevel gears for the spindles of the height adjustment devices can be provided over the length of the cross member, so that tilt-free height adjustment of the column upper parts takes place in the column lower parts, although the drive is one-sided, namely by means of the one in the right table column and the other in the left table column stored attribute waves. A height adjustment that is synchronous on both sides is also achieved via the connecting shafts. - Interchangeable manipulations such as actuating buttons, hand cranks, hand wheels or the like can be attached to the ends of the drive shafts projecting above the column lower parts. The projecting ends of the drive shafts preferably have plug-in devices for attaching hand cranks, so that both drive shafts can be actuated alternately with a single hand crank.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass ein höhenverstellbarer Tisch für Bildschirmarbeitsplätze verwirklicht wird, bei dem die Antriebswellen für die Höhenverstellvorrichtungen praktisch vollständig in dem Tischgestell bzw. einerseits in der rechten Tischsäule und andererseits in der linken Tischsäule untergebracht sind. Aus dieser gleichsam unsichtbaren Unterbringung der Antriebswellen resultiert einerseits eine in ästhetischer Hinsicht befriedigende Ausführungsform, andererseits eine vereinfachte Lagerung der Antriebswellen selbst. Denn für die Lagerung können die ohnehin vorhandenen Säulenunterteile und die sie verbindende Traverse herangezogen werden. Im Ergebnis bleiben lediglich die Betätigungsvorrichtungen für die Antriebswellen sichtbar, beispielsweise Handknöpfe oder Handkurbeln.The advantages achieved by the invention can be seen essentially in the fact that a height-adjustable table for VDU workstations is realized, in which the drive shafts for the height adjustment devices are practically completely housed in the table frame or on the one hand in the right table column and on the other hand in the left table column. This invisible placement of the drive shafts results on the one hand in an aesthetically satisfactory embodiment, and on the other hand simplifies the mounting of the drive shafts themselves. For the storage, the already existing pillar lower parts and the crossbar connecting them can be used. As a result, only the actuation devices for the drive shafts remain visible, for example hand buttons or hand cranks.
