Ein Tischgestell dieser Art ist aus der EP-A2 0 123 972 und der DE-A-3933237 bekannt. Dabei ist die Quertraverse aus einem Grundprofil-Abschnitt eines U-Profilstranges und zwei seitlichen Hohlprofilabschnitten zusammengesetzt. Die Tischbeine sind direkt mit den Verbindungsbügeln verbunden, an die der Grundprofilabschnitt und die seitlichen Hohlprofilabschnitte angeschlossen sind. Die seitlichen Hohlprofilabschnitte sind als hochkant stehende Rechteckprofilabschnitte ausgebildet, deren horizontale Schmalseiten mit durchgehenden Längsnuten versehen sind. Auf diese Weise können an den seitlichen Hohlprofilabschnitt mittels klammerartiger Befestigungsmittel Zusatzeinrichtungen angebracht werden.A table frame of this type is known from EP-A2 0 123 972 and DE-A-3933237. The crossbar is composed of a basic profile section of a U-profile strand and two lateral hollow profile sections. The table legs are directly connected to the connecting brackets, to which the basic profile section and the lateral hollow profile sections are connected. The lateral hollow profile sections are designed as upright rectangular profile sections, the horizontal narrow sides of which are provided with continuous longitudinal grooves. In this way, additional devices can be attached to the lateral hollow profile section by means of clip-like fastening means.
Dieses bekannte Tischgestell erfordert zum Aufbau der Quertraverse drei Profilabschnitte, die miteinander zu verbinden, insbesondere zu verschweißen sind. Die Quertraverse ist daher sehr aufwendig und teuer. Dasselbe gilt auch für die Verbindungsbügel, die als Gußteile ausgebildet sind und auch als Anschlußelement für eine weitere Quertraverse dienen.This known table frame requires three profile sections for the construction of the crossbeam, which sections are to be connected, in particular welded. The crossbar is therefore very complex and expensive. The same also applies to the connecting brackets, which are designed as castings and also serve as a connecting element for a further crossbar.
Es ist Aufgabe der Erfindung, ein Tischgestell der eingangs erwähnten Art zu schaffen, das aus wenigen, einfachen und kostengünstig herstellbaren Teilen mit minimalem Montageaufwand zusammengebaut werden kann, ohne das stirnseitige und seitliche Anbringen von Zusatzeinrichtungen an der Quertraverse zu beeinträchtigen.It is an object of the invention to provide a table frame of the type mentioned at the outset, which can be assembled from a few, simple and inexpensive parts which can be produced with minimal assembly effort, without impairing the frontal and lateral attachment of additional devices to the crossbar.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Quertraverse mit den Seitenwänden als Blechprofilabschnitt ausgebildet ist, daß in die Aufnahme des Blechprofilabschnittes an beiden Enden Verbindungsbügel eingesetzt sind, die mit dem Blechprofilabschnitt und den Tischbeinen verbunden sind, und daß in die Enden der als Hohlprofile ausgebildeten Seitenwände des Blechprofilabschnittes Einsatzverbinder eingeschoben sind, die stirnseitig und über Durchbrüche der Seitenwände des Blechprofilabschnittes zugängliche Befestigungsaufnahmen zum Anbringen der Zusatzeinrichtungen aufweisen.This object is achieved according to the invention in that the crossbar with the side walls is designed as a sheet profile section, that in the receptacle of the sheet profile section at both ends connecting brackets are used, which are connected to the sheet profile section and the table legs, and that in the ends of the as Hollow-profile side walls of the sheet-metal profile section insert connectors are inserted, which have fastening receptacles accessible at the front and through openings in the side walls of the sheet-metal section section for attaching the additional devices.
Die Quertraverse ist ein einfaches Blechbiegeteil, das mit den als Hohlprofile ausgebildeten Seitenwänden dennoch eine ausreichende Stabilität aufweist. Die Verbindungsbügel sind einfache Teile, die im Bereich der Knoten zwischen der Quertraverse und den Tischbeinen eine ausreichende Festigkeit sicherstellen. In die Hohlprofile werden die Einsatzverbinder eingeschoben, die so zur Tischvorderseite, zur Tischrückseite und zur Tischoberseite hin Befestigungsmöglichkeiten für Zusatzeinrichtungen bieten. Über die Stirnseiten der Einsatzverbinder läßt sich auch einfach eine Anreihverbindung zu anschließenden gleichen Arbeits-oder Bürotischen und anderen Zusatzeinrichtungen schaffen. Damit erfüllt das Tischgestell nach der Erfindung alle Anforderungen, die an einen modernen Arbeits- oder Bürotisch gestellt sind. Die Quertraverse integriert in Verbindung mit der Kabelkanal-Abdeckung zudem einen leicht zugänglichen Kabelkanal.The crossbar is a simple bent sheet metal part, which nevertheless has sufficient stability with the side walls designed as hollow profiles. The connecting brackets are simple parts that ensure sufficient strength in the area of the nodes between the crossbeam and the table legs. The insert connectors are inserted into the hollow profiles inserted, which thus offer fastening options for additional devices to the front of the table, to the back of the table and to the top of the table. Via the end faces of the insert connectors, a baying connection to the same work or office tables and other additional devices can also be easily created. The table frame according to the invention thus fulfills all the requirements placed on a modern work or office table. The crossbar also integrates an easily accessible cable duct in connection with the cable duct cover.
Nach einer Ausgestaltung ist vorgesehen, daß die Hohlprofile der Seitenwände des Blechprofilabschnittes im Querschnitt halbhohlzylinderförmig ausgebildet sind, wobei die vom Basisschenkel des Blechprofilabschnittes in die konvex gewölbten Außenabschnitte und dann in die geraden, vertikalen Innenabschnitte übergehen. Diese Form der Quertraverse ist optisch ansprechend.According to one embodiment, it is provided that the hollow profiles of the side walls of the sheet-metal profile section are semi-hollow-cylindrical in cross-section, with the transition from the base leg of the sheet-metal profile section into the convexly curved outer sections and then into the straight, vertical inner sections. This form of crossbar is visually appealing.
Für die Herstellung der Quertraverse ist nach einer Ausgestaltung vorgesehen, daß der Blechprofilabschnitt aus einem Blechzuschnitt gebogen ist, wobei die vertikalen Innenabschnitte in horizontale Befestigungsabschnitte auslaufen, die mit dem Basisschenkel fest verbunden, z.B. verschweißt sind.For the manufacture of the crossbar, it is provided according to one embodiment that the sheet metal section is bent from a sheet metal blank, the vertical inner sections ending in horizontal fastening sections which are firmly connected to the base leg, e.g. are welded.
Die leicht lösbare Verbindung zwischen dem Blechprofilabschnitt und der Kabelkanal-Abdeckung wird dadurch geschaffen, daß die Übergänge der konvex gewölbten Außenabschnitte der Seitenwände des Blechprofilabschnittes über einen abgesetzten, horizontalen Verbindungsabschnitt in die geraden, vertikalen Innenabschnitte übergehen und daß sich die Kabelkanal-Abdeckung mittels abgebogener, längsgerichteter Federstege rastend in den Verbindungsabschnitten abstützen und gehalten sind.The easily detachable connection between the sheet profile section and the cable duct cover is created in that the transitions of the convexly curved outer sections of the side walls of the sheet profile section pass over a stepped, horizontal connecting section into the straight, vertical inner sections and that the cable duct cover is merged support and hold the bent, longitudinal spring bars in the connecting sections.
Dabei kann nach einer Ausgestaltung vorgesehen sein, daß die Kabelkanal-Abdeckung als Deckel ausgebildet ist, der die offene Seite des Blechprofilabschnittes bündig verschließt.It can be provided according to one embodiment that the cable duct cover is designed as a cover which closes the open side of the sheet metal section section flush.
Das Aufnahmevermögen des Kabelkanals wird dadurch auf einfache Weise vergrößert, daß die Kabelkanal-Abdeckung im Querschnitt U-förmig mit sich spreizenden Seitenschenkeln ausgebildet ist und daß mindestens einer der Seitenschenkel mit einer eingeformten durchgehenden Griffnut versehen ist.The capacity of the cable duct is increased in a simple manner in that the cable duct cover is U-shaped in cross section with spreading side legs and that at least one of the side legs is provided with a molded-in continuous grip groove.
Ist weiterhin vorgesehen, daß die Tischbeine als Hohlprofilabschnitte mit im wesentlichen rechteckförmigem Querschnitt ausgebildet sind und daß die Basisschenkel des Blechprofilabschnittes und die Verbindungsbügel über den Hohlprofilabschnitten der Tischbeine mit Durchbrüchen versehen sind, dann können die Tischbeine zum Zuführen elektrischer Kabel verwendet werden, die leicht in die Quertraverse einführbar sind.If it is further provided that the table legs are designed as hollow profile sections with a substantially rectangular cross section and that the base legs of the sheet metal profile section and the connecting brackets are provided with openings above the hollow profile sections of the table legs, then the table legs can be used for supplying electrical cables that are easily connected to the Crossbar are insertable.
Die Tischbeine lassen sich dadurch zur Anbringung von weiteren Zusatzeinrichtungen ausnützen, daß die Schmalseitenwände als Verbindungsstege über die Breitseitenwände der als Tischbeine verwendeten Hohlprofilabschnitte hinaus verlängert sind und daß zwischen den Verbindungsstegen einer Breitseitenwand jeweils eine Kabelkanal-Abdeckung festlegbar ist.The table legs can be used for the attachment of further additional devices that the narrow side walls as connecting webs are extended beyond the wide side walls of the hollow profile sections used as table legs and that a cable duct cover can be fixed between the connecting webs of a wide side wall.
Die Stabilität im Bereich der Knoten zwischen Quertraverse und den Tischbeinen wird dadurch verbessert, daß die Einsatzverbinder im Querschnitt an den Querschnitt der als Hohlprofile ausgebildeten Seitenwände des Blechprofilabschnittes angepaßt und mit einer durchgehenden Bohrung oder Gewindebohrung versehen sind. Diese Bohrung oder Gewindebohrung dient zur leichten Ankopplung weiterer Anreihmöbel. Dabei kann auch nur vorgesehen sein, daß die Gewindebohrungen als Gewindesacklochbohrungen in die Stirnseiten der Einsatzverbinder eingebracht sind, die einfache Schraubverbindungen an den Stirnseiten der Quertraverse zulassen.The stability in the area of the knots between the crossbeam and the table legs is improved in that the Insert connectors in cross-section are adapted to the cross-section of the side walls of the sheet-metal profile section designed as hollow profiles and are provided with a continuous bore or threaded bore. This hole or threaded hole is used for easy coupling of additional modular furniture. It can also be provided that the threaded holes are drilled as threaded blind holes in the end faces of the insert connectors, which allow simple screw connections on the end faces of the crossbar.
Anbaumöglichkeiten im Bereich der Längskanten der Quertraverse werden dadurch geschaffen, daß die Einsatzverbinder den konvex gewölbten Außenabschnitten der Seitenwände des Blechprofilabschnittes zugekehrt mittels Ausnehmungen in vorgegebenem Raster angeordnete Verbindungsstege unterteilt ist und daß Zusatzeinrichtungen, wie Tragarme, oder Stützen, durch die konvex gewölbten Außenabschnitte der Seitenwände hindurch mit diesen Verbindungsstegen verbindbar, z.B. verschraubbar sind.Possibilities of attachment in the area of the longitudinal edges of the crossbar are created in that the insert connectors facing the convexly curved outer sections of the side walls of the sheet-metal section are subdivided by means of recesses arranged in a predetermined grid, and that additional devices, such as support arms or supports, are divided through the convexly curved outer sections of the side walls connectable with these connecting bars, e.g. are screwable.
Da sich die Verbindungsstege nahezu über 180° erstrecken, steht auch dieser Winkelbereich für den Anbau von Zusatzeinrichtungen zur Verfügung. Dabei ist zu beachten, daß die Winkelbereiche an bei den konvexen Außenabschnitten der Quertraverse aneinander anschließen.Since the connecting webs extend almost over 180 °, this angular range is also available for the attachment of additional devices. It should be noted that the angular areas connect to each other at the convex outer sections of the crossbar.
Wird der Arbeits- oder Bürotisch freistehend verwendet, dann ist nach einer weiteren Ausgestaltung vorgesehen, daß die Stirnseiten der Quertraverse mittels Abschlußelementen abdeckbar sind.If the work or office table is used freestanding, then according to a further embodiment it is provided that the end faces of the crossbar can be covered by means of end elements.
Ein bevorzugtes Ausführungsbeispiel sieht vor, daß die Quertraverse um einen vorgegebenen Betrag über die als Hohlprofilabschnitte ausgebildeten Tischbeine hinausragt, um beim Aneinanderreihen gleicher Arbeits- oder Bürotische einen ausreichenden Abstand zwischen den Tischbeinen benachbarter Arbeits- oder Bürotische zu erhalten.A preferred embodiment provides that the crossbar projects by a predetermined amount beyond the table legs designed as hollow profile sections, in order to maintain a sufficient distance between the table legs of adjacent work or office tables when the same work or office tables are lined up.

Dabei laufen die geraden, vertikalen Innenabschnitte 23 und 24 in horizontale Befestigungsabschnitte aus, die fest mit dem Basisschenkel des Blechprofilabschnittes 20 verbunden, z.B. verschweißt sind. Um die offene Seite des Blechprofilabschnittes 20 zu verschließen, wird die Kabelkanal-Abdeckung 28 verwendet, deren Seitenschenkel sich zu den freien Enden hin spreizen und in Federstege 29 auslaufen. Diese Federstege 29 rasten in die horizontalen Verbindungsabschnitte 25 und 26 des Blechprofilabschnittes 29 ein, die an den Übergängen von den konvex gewölbten Außenabschnitten 21 und 22 zu den geraden, vertikalen Innenabschnitten 23 und 24 abgesetzt sind, so daß sich die Federstege 29 darin verrasten können. Die Kabelkanal-Abdeckung 28 vervollständigt den Kabelkanal 27 mit großem Querschnitt. Wie Fig. 6 zeigt, kann die Kabelkanal-Abdeckung 28 auch die offene Seite des Blechprofilabschnittes 20 bündig verschließen.In Fig. 2, the base element of the crossbar, the
Der Querschnitt der Tischbeine 30 ist in Fig. 3 gezeigt. Das Tischbein 30 umfaßt den Hohlprofilabschnitt 31, der einen im wesentlichen rechteckförmigen Querschnitt hat. Die Schmalseitenwände 32 des Hohlprofilabschnittes 31 sind über die Breitseitenwände des Hohlprofilabschnittes 31 hinaus als Verbindungsstege 33 und 34 verlängert. Zwischen die Verbindungsstege 33 bzw. 34 einer Breitseitenwand kann die Kabelkanal-Abdeckung 35 eingerastet werden. Dabei weisen die Verbindungsstege 33 und 34 leichte Hinterschneidungen auf, in die an der Kabelkanal-Abdeckung 35 angeformte Raststege einrasten. Auf diese Weise bilden sich an beiden Breitseitenwänden des Hohlprofilabschnittes 31 Kabelkanäle 36, die durch Abnehmen der Kabelkanal-Abdeckungen 35 leicht zugänglich sind.The cross section of the
Wie die Fig. 6 zeigt, wird an beiden Enden des Blechprofilabschnittes 20 ein Verbindungsbügel 36 eingesetzt. Die Seitenschenkel 37 der Verbindungsbügel 36 werden fest mit den geraden, vertikalen Innenabschnitten 23 und 24 der Seitenwände des wannenartigen Blechprofilabschnittes 20 verbunden, z.B. verschraubt. Der Mittelschenkel des Verbindungsbügels 36 wird zusammen mit dem Basisschenkel des Blechprofilabschnittes 20 mit dem Hohlprofilabschnitt 31 des Tischbeines 30 verbunden, z.B. verschweißt oder verschraubt. Damit erhält der Knoten zwischen der Quertraverse und dem Tischbein 30 eine ausgezeichnete Stabilität.As shown in FIG. 6, a connecting
In die Hohlprofile der Seitenwände des Blechprofilabschnittes 20 werden Einsatzverbinder 50 eingesteckt, die im Querschnitt auf den Querschnitt der Hohlprofile abgestimmt sind. Diese Einsatzverbinder 50 weisen eine durchgehende Bohrung 51 oder eine Gewindebohrung auf, die auch nur als stirnseitige Gewindesacklochbohrung ausgebildet sein kann. Damit werden stirnseitig Anschlußmöglichkeiten für andere Arbeits- oder Bürotische sowie andere Zusatzeinrichtungen geschaffen. Werden diese Anschlußmöglichkeiten nicht genützt, dann werden die Stirnseiten mit den Abschlußelementen 60 nach Fig. 1 verschlossen. Dabei können die Bohrungen 51 oder die Gewindebohrungen in den Einsatzverbindern 50 mit verwendet werden.
In Längsrichtung sind die Einsatzverbinder 50 durch Ausnehmungen 52 in vorgegebenem Raster in Verbindungsstege 54 unterteilt, die satt an den konkaven Innenseiten der konvex gewölbten Außenabschnitte 21 und 22 der Hohlprofile des Blechprofilabschnittes 20 anliegen. Durch Schraubverbindungen können Zusatzeinrichtungen direkt an den Einsatzverbindern 50 angeschraubt werden, wobei die Schrauben die konvex gewölbten Außenabschnitte 21 und 22 durchdringen und in Gewindebohrungen der Verbindungsstege 54 eingeschraubt sind. Auf diese Weise kann z.B. das kreisbogenförmige, schwalbenschwanzförmige Führungselement 41 befestigt werden, an dem der Tragarm 40 mit einer entsprechenden kreisbogenförmigen Schwalbenschwanznut begrenzt verschwenkbar ist.In the longitudinal direction, the
Es ist auch möglich, Zusatzeinrichtungen durch Durchbrüche in den konvex gewölbten Außenabschnitten 21 und 22 in die Ausnehmungen 52 der Einsatzverbinder 50 einzuführen und dort mit einem in die Bohrung 51 eingeführten Bolzen festzulegen.It is also possible to insert additional devices through openings in the convexly curved
Wie die Fig. 4 und 5 zeigen, kann der Verbindungsbügel 36 auch fest mit dem Hohlprofilabschnitt 31 des Tischbeines 30 verschweißt sein und eine Einheit bilden. Die Quertraverse, d.h. der Blechprofilabschnitt 20 wird dann zwischen die Seitenschenkel 37 des Verbindungsbügels 36 eingebracht und mit diesen oder dem Mittelschenkel des Verbindungsbügels 36 verbunden. Die Fig. 4 und 5 zeigen auch, daß der Verbindungsbügel 36 so ausgespart ist, wie der Durchbruch 38 zeigt, daß vom Hohlraum des Tischbeines 30 ein direkter Zugang zum Kabelkanal 27 der Quertraverse besteht, wenn auch der Basisschenkel des Blechprofilabschnittes 20 entsprechend ausgespart ist.4 and 5 show, the connecting
