Description

Hubgestell für einen höhenverslellbaren Tisch Lifting frame for a height-adjustable table
Die Erfindung betrifft ein Hubgestell für einen höhenvcrstcllbaren Tisch, insbesondere einen höhenverstellbaren Einsäulentisch, wobei mehrere konzentrisch ineinander verschieblich gelagerte Rohre vorgesehen sind, wobei ein inneres Rohr eine Hubeinrichtung aufweist.The invention relates to a lifting frame for a height-adjustable table, in particular a height-adjustable single-column table, wherein a plurality of tubes which are concentrically displaceable one inside the other are provided, an inner tube having a lifting device.
Aus der DE 44 37 392 ist ein Tischgcstcll bekannt, bei der ein Befestigungsabschnitt vorgesehen ist, der eine innere Kontur zur Aufnahme eines Tischbeines in unterschiedlichen Darstellungen aufweist. Zur Fixierung des Beines in dem Befestigungsabschnitt sind gesonderc Bcfcstigungsmittel vorgesehen.From DE 44 37 392 a Tischgcstcll is known, in which a fastening section is provided which has an inner contour for receiving a table leg in different representations. Separate securing means are provided for fixing the leg in the fastening section.
Aus der DE 39 38 496 ist ein Untergestell für einen höhenvcrstcllbaren Einsäulcntisch bekannt, der aus einem Verbund aus mindestens drei zu einer Säule angeordneten Führungscinrichtungcn besteht, wobei wenigstens eine der Führungscinrichtungen eine Gasfeder aufweist. Zur Höhcnverstcllung ist hierbei vorgesehen, daß im Bereich der Gasfcdcr ein Kegel angeordnet ist, wobei der Kegel eine korrespondierend hierzu ausgebildete Brcmscinrichtung aufweist, die auf die Innenwandung der äußeren Führungscinrichlung dieser Vorrichtung wirkt. Im einzelnen besteht die aus dem Stand der Technik bekannte Vorrichtung aus mehreren konzentrisch ineinander gelagerten Führungseinrichtungen in Form von Rohren, die gegeneinander verschieblich sind, und die auch gegeneinander abgestützt gelagert werden müssen. Nachteilig an dieser bekannten Vorrichtung ist ein relativ hoher Bauaufwand, der eine derartige Vorrichtung teuer macht.From DE 39 38 496 a base frame for a height-adjustable one-column table is known, which consists of a composite of at least three guide device arranged to a column, at least one of the guide devices having a gas spring. For height adjustment, it is provided here that a cone is arranged in the area of the gas surface, the cone having a correspondingly designed bridging device which acts on the inner wall of the outer guiding device of this device. In particular, the device known from the prior art consists of several concentrically nested guide devices in the form of tubes which are displaceable against each other and which must also be supported against each other. A disadvantage of this known device is a relatively high construction cost, which makes such a device expensive.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Gestell der eingangs genannten Art für einen höhenvcrstcllbaren Tisch zu schaffen, das einfach und preiswert in der Herstellung ist, und darüber hinaus eine einfache Handhabung bei der Höhenverstellung zuläßt.The invention is therefore based on the object of creating a frame of the type mentioned for a height-adjustable table which is simple and inexpensive to manufacture and moreover allows easy handling in the height adjustment.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Hubgestell zwei Rohre umfaßt, die durch eine Verdrehung relativ zueinander miteinander klemmbar fixierbar sind. Vorteilhaft bei dieser Konstruktion ist, daß keinerlei zusätzliche Bremsmittcl erforderlich sind, um die beiden Rohre des Hubgestclls in einer bestimmten Lage zu fixieren; darüber hinaus ist das Hubgestell im verklemmten Zustand der beiden Rohre miteinander völlig spiel- und damit wackelfrei. Im einzelnen ist hierbei vorgesehen, daß die Form der Rohre derart ist, daß die Rohre bei Verdrehung relativ zueinander an zwei Stellen miteinander klemmend in Verbindung stehen. Hierzu sind die Rohre vorteilhaft eiförmig oder oval ausgebildet. Hieraus folgt, daß zur Höhenvcrstcllung lediglich die Tischplatte leicht verdreht werden muß, damit die beiden miteinander klemmend verbundenen Rohre außer Eingriff gebracht werden können, um dann entweder die Tischplatte hochzustellen, oder aber die Tischplatte durch Druck von oben gegen die Kraft der Hubeinrichtung, beispielsweise einer Gasdruckfeder, nach unter zu drücken. Nach Erreichen der gewünschten Höhe wird dann die Tischplatte wieder etwas verdreht, wobei sich bei diesem Verdrehvorgang die beiden konzentrisch ineinander gelagerten Rohre ineinander verklemmen bzw. verkanten, wobei hierdurch dann die Fixierung der Tischplatte auf einer bestimmten Höhe ermöglicht wird.The object is achieved in that the lifting frame comprises two tubes which can be clamped relative to one another by twisting. The advantage of this construction is that no additional brake means are required to fix the two tubes of the lifting frame in a certain position; In addition, the lifting frame is completely free of play and therefore wobble-free when the two tubes are clamped together. In particular, it is provided here that the shape of the tubes is such that the tubes are connected to one another in a clamping manner when twisted relative to one another. For this purpose, the tubes are advantageously egg-shaped or oval. From this it follows that only the table top has to be rotated slightly in order to raise the height so that the two tubes which are connected by clamping can be disengaged, in order then either to raise the table top or to press the table top against the force of the lifting device, for example one Gas spring to push down. After reaching the desired height, the table top is then slightly rotated again, the two concentrically nested tubes jamming or tilting in this twisting process, which then enables the table top to be fixed at a certain height.
Nach einem weiteren Merkmal der Erfindung weist das eine Rohr eine Trägerplatte und das andere Rohr ein Fußelement auf. Weilerhin ist vorgesehen, daß die Kolbenstange der Gasdruckfeder am Fußclcmenl und der Zylinder der Gasdruckfcdcr an der Trägcrplatte angeordnet ist. Die Trägcrplatte dient hierbei der Aufnahme der Tischplatte. An das Fußelcment kann ein entsprechender Fuß angebracht werden.According to a further feature of the invention, the one tube has a carrier plate and the other tube has a foot element. Because of this, it is provided that the piston rod of the gas pressure spring is arranged on the base plate and the cylinder of the gas pressure plate is arranged on the support plate. The carrier plate serves to accommodate the Table top. A corresponding foot can be attached to the foot element.
Anhand der Zeichnung wird die Erfindung nachstehend beispielhaft näher erläutert.The invention is explained in more detail below by way of example with reference to the drawing.
Figur 1 zeigt das Hubgestell in einer Seitenansicht;Figure 1 shows the lifting frame in a side view;
Figur 2 zeigt einen Schnitt gemäß der Linie II - II aus Figur 1 ;Figure 2 shows a section along the line II - II of Figure 1;
Figur 3 zeigt eine Darstellung gemäß Figur 2, wobei jedoch die beiden konzentrisch ineinander gelagerten Rohre des Hubgestells gegeneinander verdreht sind.FIG. 3 shows a representation according to FIG. 2, but the two concentrically nested tubes of the lifting frame are rotated relative to one another.
Gemäß Figur 1 besteht das insgesamt mit 1 bezeichnete Hubgcslcll aus den beiden konzentrisch ineinander parallel zur Längsachse vcrschicblich gelagerten Rohren 10 und 1 1 , wobei das innere Rohr 1 1 den Zylinder 21 . der insgesamt die mit 20 bezeichneten Gasdruckfeder aufnimmt. Der Zylinder 21 der Gasruckfeder 20, die in dem inneren Rohr 1 1 gelagert ist, ist an der Trägcrplatte 30 angclcnkt, die der Aufnahme der Tischplatte dient. Die Kolbenstange 22 der Gasdruckfeder 20 stützt sich demgegenüber am Fußelcment 40 ab. Entgegen der Kraft der Ga.sdruckfeder 20 oder durch die Kraft der Gasdruckfcdcr 20 werden nun die beiden konzentrisch ineinander gelagerten Rohre 10 und 11 teleskopartig verlängert oder verkürzt.According to FIG. 1, the overall stroke number 1 is composed of the two tubes 10 and 11 which are mounted concentrically one inside the other parallel to the longitudinal axis, the inner tube 11 being the cylinder 21. which receives the gas pressure spring labeled 20 in total. The cylinder 21 of the gas spring 20, which is mounted in the inner tube 11, is attached to the support plate 30, which serves to receive the table top. In contrast, the piston rod 22 of the gas pressure spring 20 is supported on the foot element 40. Contrary to the force of the gas pressure spring 20 or by the force of the gas pressure spring 20, the two tubes 10 and 11, which are mounted concentrically one inside the other, are now extended or shortened telescopically.
Die Ausbildung der Rohre 10 und 11 des Hubgestclls ergibt sich aus den Figuren 2 und 3. So ist insbesondere aus diesen Figuren erkennbar, daß die konzentrisch ineinander gelagerten Rohre 10 und 11 des Hubgestells 1 oval ausgebildet sind, und mit Abstand zueinander ineinander gelagert sind. Hierbei ist wesentlich, daß die Hauptachse des ovalen oder elliptischen inneren Rohres, bezogen auf den Außcndurchmcsscr, größer ist, als die Nebenachse des äußeren Rohres 10, bezogen auf den Innenradius. Ist dies nicht der Fall , wäre eine Vcrklcmmung der beiden Rohre durch Verdrehung, wie in Figur 3 dargestellt, nicht möglich. The design of the tubes 10 and 11 of the lifting frame results from FIGS. 2 and 3. It can be seen in particular from these figures that the tubes 10 and 11 of the lifting frame 1, which are concentrically nested in one another, are oval in shape and are spaced one from the other. It is essential here that the main axis of the oval or elliptical inner tube, based on the outer diameter, is larger than the minor axis of the outer tube 10, based on the inner radius. If this is not the case, a twisting of the two pipes by twisting, as shown in FIG. 3, would not be possible.
