Description

Die Erfindung bezieht sich auf einen Tisch nach dem Oberbegriff des Anspruches 1. Ein derartiger Tisch ist aus der DE-A-32 11 940 bekannt.The invention relates to a table according to the preamble of claim 1. Such a table is known from DE-A-32 11 940.

Aus der DE-OS 33 23 780 ist ein Tisch vorbekannt, bei dem die Höhenverstellung der Tischplatte mittels eines Parallelogrammgestänges erfolgt, wobei eine Rastscheibe vorgesehen ist, um die Höhenverstelleinrichtung in einzelnen Raststufen zu arretieren. Gänzlich unabhängig davon ist es möglich, die Neigung der Tischplatte mittels eines separaten Mechanismus, beispielsweise eines Stützarmes oder ähnlichem einzustellen. Tische der genannten Art werden beispielsweise als Zeichentische verwendet, wobei sich in Abhängigkeit von den jeweils durchzuführenden Arbeiten eine entsprechende Einstellung der Tischplatte ergibt. Um rationell arbeiten zu können, ist es deshalb nötig, sowohl die Höheneinstellung als auch die Kippung der Tischplatte schnell und einfach verändern zu können. Bei dem bekannten Tisch sind hierzu separate Mechanismen zu betätigen, welche einerseits kompliziert aufgebaut sind und andererseits jeweils unabhängig voneinander eingerastet oder gelöst werden müssen.From DE-OS 33 23 780 a table is previously known in which the height adjustment of the table top is carried out by means of a parallelogram linkage, a locking disc being provided in order to lock the height adjustment device in individual locking stages. Completely independently of this, it is possible to adjust the inclination of the table top by means of a separate mechanism, for example a support arm or the like. Tables of the type mentioned are used, for example, as drawing tables, the table top being correspondingly adjusted depending on the work to be carried out in each case. In order to be able to work efficiently, it is therefore necessary to be able to quickly and easily change both the height setting and the tilt of the table top. In the known table, separate mechanisms have to be actuated for this purpose, which on the one hand have a complicated structure and on the other hand must be locked or released independently of each other.

Ein ähnlicher Tisch ist aus der DE-OS 38 90 499 vorbekannt, auch hierbei dient eine Parallelogrammlenkeranordnung zur Höhenverstellung der Tischplatte, wobei eine Arretier- oder Bremsvorrichtung vorgesehen ist, um die gewählte Höheneinstellung zu fixieren. Eine Verstellung der Neigung der Tischplatte ist hierbei nicht vorgesehen.A similar table is previously known from DE-OS 38 90 499, here too a parallelogram handlebar arrangement is used to adjust the height of the table top, with a locking or braking device being provided to fix the selected height setting. An adjustment of the inclination of the table top is not provided here.

Der Erfindung liegt die Aufgabe zugrunde, einen Tisch der eingangs genannten Art zu schaffen, welcher bei einfachem Aufbau und kostengünstiger Herstellbarkeit mit einem einfach, betriebssicher und schnell zu bedienenden Arretiersystem versehen ist.The invention has for its object to provide a table of the type mentioned, which is provided with a simple, reliable and quick-to-use locking system with a simple structure and inexpensive to manufacture.

Erfindungsgemäß wird die Aufgabe mit den Merkmalen des Anspruches 1 gelöst.According to the invention the object is achieved with the features of claim 1.

Der erfindungsgemäße Tisch zeichnet sich durch eine Reihe erheblicher Vorteile aus. Da nur eine Arretiereinrichtung verwendet wird, kann die Bedienungsperson die Tischplatte in der gewünschten Weise positionieren, d.h. in der Höhe verstellen und kippen. Sobald diese gewünschte Position erreicht ist, kann die Bedienungsperson mittels eines einzigen Handgriffs durch Betätigung der einen Arretiereinrichtung die Tischplatte in ihrer Lage fixieren.The table according to the invention is characterized by a number of considerable advantages. Since only one locking device is used, the operator can position the table top in the desired manner, i.e. adjust in height and tilt. As soon as this desired position is reached, the operator can fix the table top in position by means of a single handle by actuating the one locking device.

Besonders günstig ist es, wenn die erfindungsgemäße Arretiereinrichtung stufenlos einstellbar ist, da dann die Bedienungsperson bei gelöster Arretiereinrichtung die Tischplatte in jede beliebige Stellung bringen und in dieser arretieren kann.It is particularly favorable if the locking device according to the invention is infinitely adjustable, since the operator can then bring the tabletop into any position and lock it in this position when the locking device is released.

In günstiger Ausgestaltung der Erfindung ist vorgesehen, daß die Arretiereinrichtung eine horizontale Stange umfaßt, an deren einem Ende zur Klemmung ein Exzenter gelagert ist und welche eine an der Tischplatte gelagerte Kippeinrichtung und eine an dem Fußgestell gelagerte Höhenverstelleinrichtung durchgreift. Diese Ausgestaltungsform ist deshalb besonders vorteilhaft, da eine Klemmung durch einen Exzenter erfolgt, welcher einfach und zuverlässig bedienbar ist und die Aufbringung einer hohen Klemmkraft ermöglicht. Weiterhin ermöglicht die Verwendung der horizontalen Stange eine doppelte Ausbildung der Parallelogrammlenkeranordnung, so daß der gesamte Tisch in hohem Maße stabil und kippsicher ist. Auch bei einer größeren Länge der horizontalen Stange kann unter Verwendung einer einzigen Exzentereinrichtung eine sichere Arretierung und Klemmung erreicht werden.In a favorable embodiment of the invention it is provided that the locking device comprises a horizontal rod, at one end of which an eccentric is mounted for clamping and which engages through a tilting device mounted on the table top and a height adjustment device mounted on the base frame. This embodiment is particularly advantageous because it is clamped by an eccentric, which is easy and reliable to operate and enables a high clamping force to be applied. Furthermore, the use of the horizontal bar enables the parallelogram handlebar arrangement to be designed twice, so that the entire table is highly stable and tipping-proof. Even with a longer length of the horizontal rod, secure locking and clamping can be achieved using a single eccentric device.

Die Höhenverstelleinrichtung weist zumindest zwei Parallelogrammlenker auf, nämlich einen oberen und einen unteren, welche schwenkbar mit jeweils einem Ende an einer vertikalen Säule des Fußgestells sowie an einem Vertikalträger gelagert sind. Es versteht sich, daß zwei vertikale Säulen vorgesehen sein können, an denen jeweils ein Paar von Parallelogrammlenkers gelagert sind. Infolgedessen können auch zwei zueinander parallele Vertikalträger verwendet werden, um die Kippsicherheit des Tisches zu erhöhen. Der obere Bereich des Vertikalträgers trägt dabei die Tischplatte. Um eine Arretierung der Höhenverstellbarkeit zu erreichen, ist an dem oberen Parallelogrammlenker schwenkbar ein Ende eines Zwischenlenkers gelagert, dessen anderes Ende im Bereich der Arretiervorrichtung von der horizontalen Stange durchgriffen wird. Bei einer Verschwenkung der Parallelogrammlenkeranordnung ergibt sich somit eine Verschwenkung oder Verkippung des Zwischenlenkers, so daß dieser relativ zu der horizontalen Stange in unterschiedlichen Positionen klemmbar ist. Der Zwischenlenker ist zur Durchführung der horizontalen Stange mit einem Langloch versehen.The height adjustment device has at least two parallelogram links, namely an upper and a lower one, which are pivotably supported with one end each on a vertical column of the base frame and on a vertical support. It is understood that two vertical columns can be provided, on each of which a pair of parallelogram links are mounted. As a result, two vertical supports that are parallel to each other can also be used to increase the tilt resistance of the table. The upper area of the vertical support supports the table top. In order to achieve a locking of the height adjustability, one end of an intermediate link is pivotally mounted on the upper parallelogram link, the other end of which is penetrated by the horizontal rod in the area of the locking device. When the Parallelogram link arrangement thus results in a pivoting or tilting of the intermediate link, so that it can be clamped in different positions relative to the horizontal rod. The intermediate link is provided with an elongated hole for the passage of the horizontal rod.

Die Kippeinrichtung ist in bevorzugter Weise so ausgebildet, daß diese zumindest einen sich senkrecht zur Tischplatte erstreckenden, an der Tischplatte befestigten Träger aufweist, welcher um die horizontale Achse schwenkbar am oberen Ende des Vertikalträgers gelagert ist. Der Träger ist mit einem bogenförmigen Schlitz versehen, dessen Mittelpunkt die horizontale Achse bildet. Durch den bogenförmigen Schlitz erstreckt sich die horizontale Stange. Auf diese Weise kann die jeweilige Kippstellung der Tischplatte durch die in dem bogenförmigen Schlitz gleitende horizontale Stange arretiert werden.The tilting device is preferably designed in such a way that it has at least one support which extends perpendicular to the table top and is fastened to the table top and which is pivotably mounted about the horizontal axis at the upper end of the vertical support. The carrier is provided with an arcuate slot, the center of which forms the horizontal axis. The horizontal bar extends through the arcuate slot. In this way, the respective tilting position of the table top can be locked by the horizontal rod sliding in the arcuate slot.

Um die Klemmkraft einzustellen, ist am freien Ende der horizontalen Stange ein einstellbares Widerlager vorgesehen, beispielsweise in Form einer auf die horizontale Stange aufgeschraubten Mutter.In order to adjust the clamping force, an adjustable abutment is provided at the free end of the horizontal rod, for example in the form of a nut screwed onto the horizontal rod.

Der Exzenter ist erfindungsgemäß bevorzugterweise mittels eines Handhebels betätigbar, wobei dieser in günstiger Weiterbildung längenveränderbar ausgestaltet sein kann. Hierdurch ist es möglich, den Handhebel nach Arretierung der Tischplatte unter diese einzuschieben, so daß der Handhebel nicht stört und so daß unbeabsichtigte Bewegungen des Handhebels vermieden werden.According to the invention, the eccentric can preferably be actuated by means of a hand lever, which, in a favorable further development, can be designed to be variable in length. This makes it possible to insert the hand lever after locking the table top under it so that the hand lever does not interfere and so that unintentional movements of the hand lever are avoided.

Zur Erleichterung der Bedienbarkeit kann es günstig sein, wenn die Kippeinrichtung und die Höhenverstelleinrichtung jeweils mit einer Einrichtung zum Gewichtsausgleich versehen sind, beispielsweise einer Federeinrichtung o.ä.To facilitate operability, it can be advantageous if the tilting device and the height adjustment device are each provided with a device for weight compensation, for example a spring device or the like.

Die Fig. 1 und 2 zeigen jeweils Seitenansichten des erfindungsgemäßen Tisches in unterschiedlichen Stellungen der Tischplatte. Der Tisch umfaßt ein Fußgestell 1, an welchem Zwei vertikale Säulen 8 befestigt sind, welche aus Gründen der Versteifung mittels Querträgern verbunden sind. Das Fußgestell weist, wie üblich, zwei horizontale Streben auf, es kann jedoch in beliebiger anderer Weise ausgebildet sein. An den vertikalen Säulen sind zwei zueinander parallele Parallelogrammlenker 6, 7 schwenkbar gelagert, an deren freiem Ende ein Vertikalträger 9 schwenkbar gelagert ist. Eine Einrichtung 16 zum Gewichtsausgleich dient zur entsprechenden Abstützung oder Abfederung des oberen Lenkers 6. In einem Abstand vom Anlenkpunkt 19 des oberen Lenkers 6 an den Vertikalträger 9 ist an einem Anlenkpunkt 20 ein Zwischenlenker 10 schwenkbar gelagert, welcher sich im wesentlichen parallel zu dem Vertikalträger 9 erstreckt.1 and 2 each show side views of the table according to the invention in different positions of the table top. The table comprises a base frame 1, to which two vertical columns 8 are attached, which are connected by means of cross members for reasons of stiffening. The base frame, as usual, has two horizontal struts, but it can be designed in any other way. On the vertical columns, two parallelogram links 6, 7 parallel to one another are pivotally mounted, at the free end of which a vertical support 9 is pivotally mounted. A device 16 for weight compensation serves for corresponding support or suspension of the upper link 6. At a distance from the articulation point 19 of the upper link 6 to the vertical support 9, an intermediate link 10 is pivotally mounted on an articulation point 20, which is essentially parallel to the vertical support 9 extends.

An dem oberen Endbereich des Vertikalträgers 9 ist eine horizontale Achse 2 vorgesehen, um welche eine Tischplatte 3 kippbar ist. Im einzelnen dient hierzu ein Träger 12, welcher sich, wie insbesondere aus Fig. 7 ersichtlich ist, im rechten Winkel zu der Tischplatte 3 erstreckt. Eine Einrichtung 17, beispielsweise in Form einer Feder, dient zur Abfederung und Aufnahme des Gewichts der Tischplatte 3 bei deren Kippung.At the upper end region of the vertical support 9, a horizontal axis 2 is provided, around which a table top 3 can be tilted. In particular, a carrier 12 is used for this purpose, which, as can be seen in particular from FIG. 7, extends at right angles to the table top 3. A device 17, for example in the form of a spring, serves to cushion and absorb the weight of the table top 3 when it is tilted.

Mit der oben beschriebenen Konstruktion ist es möglich, die Tischplatte 3 in der Höhe zu verstellen und zu verkippen. Im nachfolgenden wird der erfindungsgemäße Brems- oder Arretiermechanismus beschrieben.With the construction described above, it is possible to adjust and tilt the table top 3. The braking or locking mechanism according to the invention is described below.

Am oberen Endbereich des Vertikalträgers 9 ist, etwa in Höhe der horizontalen Achse 2, eine horizontale Stange 4 angeordnet, welche sich frei verschiebbar durch den Vertikalträger 9 erstreckt (siehe Fig. 7). Die horizontale Stange 4 erstreckt sich weiterhin durch ein Langloch 11, welches in vertikaler Richtung am Endbereich des Zwischenlenkers 10 ausgebildet ist. Weiterhin erstreckt sich die horizontale Stange 4 durch einen bogenförmigen Schlitz 13 des Trägers 12. Die horizontale Stange 4 behindert somit weder die Verschwenkung der Tischplatte 3 noch die Horizontalverstellung mittels des Parallelogrammgestänges, da der bogenförmige Schlitz 13 ebenso eine Bewegung des Träger 12 zuläßt, wie das Langloch 11 eine Bewegung des Zwischenlenkers 10 ermöglicht.At the upper end region of the vertical support 9 is approximately in height the horizontal axis 2, a horizontal rod 4 is arranged, which extends freely through the vertical support 9 (see Fig. 7). The horizontal rod 4 also extends through an elongated hole 11, which is formed in the vertical direction at the end region of the intermediate link 10. Furthermore, the horizontal rod 4 extends through an arcuate slot 13 of the carrier 12. The horizontal rod 4 thus does not hinder the pivoting of the table top 3 nor the horizontal adjustment by means of the parallelogram linkage, since the arcuate slot 13 also allows the carrier 12 to move, as is the case Elongated hole 11 allows movement of the intermediate link 10.

Die Fig. 7 zeigt, daß an einem Ende der horizontalen Stange 4 ein Widerlager 14 vorgesehen ist, welches in Form einer Mutter ausgebildet ist und somit eine Einstellmöglichkeit bietet. An dem anderen Ende der horizontalen Stange 4 ist ein Exzenter 5 vorgesehen, welcher durch Drehung eines Handhebels 15, welcher mit einem Handgriff 21 versehen ist, in verschiedene Stellungen gebracht werden kann, so daß eine Klemmung zwischen den Vertikalträgern 9, den Trägern 12 und dem Zwischenlenker 10 auftritt, welche eine Arretierung oder Bremsung der Tischplatte 3 in einer beliebigen Stellung bewirkt. Die Fig. 5 und 6 zeigen im Vergleich unterschiedliche Stellungen des Exzenters 5, aus welchen sich der mögliche Spannweg 22 ergibt.Fig. 7 shows that an abutment 14 is provided at one end of the horizontal rod 4, which is designed in the form of a nut and thus offers an adjustment option. At the other end of the horizontal rod 4, an eccentric 5 is provided, which can be brought into different positions by rotating a hand lever 15, which is provided with a handle 21, so that a clamping between the vertical supports 9, the supports 12 and the Intermediate link 10 occurs, which causes a locking or braking of the table top 3 in any position. 5 and 6 show in comparison different positions of the eccentric 5, from which the possible clamping path 22 results.

Die Fig. 4 zeigt, daß parallel nebeneinander zwei Exzenter 5 vorgesehen sind, welche in Form von Kugellagern ausgebildet sind. Hierdurch ergeben sich günstige Kraft- und Reibungsverhältnisse. Die Innenringe der beiden Kugellager sind auf ein Rohr 23 aufgesetzt, in welchem der eigentliche Handhebel 15 verschiebbar gelagert ist. Hierdurch ist es möglich, den Handhebel bei Nichtgebrauch unter die Tischplatte 3 einzuschieben. Um eine Verdrehung des Rohres 23 zu ermöglichen, weist dieses an seinem freien Ende einen Schlitz 24 auf, in welchem ein Quer-Bolzen 25 des Handhebels 15 einsteckbar ist. Der Bolzen 25 und der Schlitz 24 bilden somit eine Kupplung. Das vordere Ende des Handhebels 15 ist einem Halteblech 26 aufgenommen und abgestützt.Fig. 4 shows that two eccentrics 5 are provided in parallel, which are designed in the form of ball bearings. This results in favorable force and friction conditions. The inner rings of the two ball bearings are placed on a tube 23 in which the actual hand lever 15 is slidably mounted. This makes it possible to insert the hand lever under the table top 3 when not in use. In order to enable the tube 23 to be rotated, it has a slot 24 at its free end, in which a cross pin 25 of the hand lever 15 can be inserted. The bolt 25 and the slot 24 thus form a coupling. The front end of the hand lever 15 is received and supported by a holding plate 26.

Wie insbesondere in Fig. 3 dargestellt, sind parallel zu dem Zwischenlenker 10 Laschen 27 vorgesehen, welche ebenfalls ein Langloch aufweisen und an dem Zwischenlenker 10 gelagert sind. Derartige Laschen können auch, wie in Fig. 7 gezeigt, im Innenraum des Zwischenlenkers 10 angebracht sein. Sie dienen zusammen mit Unterlegscheiben 28 der Reibungserhöhung, wobei die Unterlegscheiben 28, wie ebenfalls aus Fig. 7 ersichtlich, jeweils zwischen den einzelnen Elementen angeordnet sein können.As shown in particular in FIG. 3, 10 tabs 27 are provided parallel to the intermediate link, which also have an elongated hole and are mounted on the intermediate link 10. Such tabs can also, as shown in FIG. 7, be attached in the interior of the intermediate link 10. Together with washers 28, they serve to increase the friction, whereby the washers 28, as can also be seen in FIG. 7, can each be arranged between the individual elements.

Zur Verstellung des erfindungsgemäßen Tisches zieht die Bedienungsperson zunächst mittels des Handgriffs 21 den Handhebel 15 nach außen, so daß der Bolzen 25 in den Schlitz 24 eingreift. Hierdurch ist durch Drehung des Handgriffs 21 eine Drehung des Rohres 23 möglich, durch welche der Exzenter 5 in die gelöste Stellung verdreht wird. Nunmehr ist es möglich, die Tischplatte 3 sowohl in der Höhe als auch in der Neigung zu verstellen, da die horizontale Stange 4 frei in dem Langloch 11 bzw. dem bogenförmigen Schlitz 13 verschiebbar ist. Sobald die gewünschte Stellung der Tischplatte 3 erreicht ist, dreht die Bedienungsperson wieder den Handgriff 21, wodurch der Exzenter 5 in seine Sperrstellung gebracht wird. Sollte die Klemmkraft nicht ausreichen, so kann durch Nachstellen des Widerlagers 14 ein entsprechender Ausgleich geschaffen werden. Die Bedienungsperson kann jetzt den Handhebel 15 unter die Tischplatte 3 einschieben, ohne daß hierdurch der Klemmvorgang beeinträchtigt würde.To adjust the table according to the invention, the operator first pulls the hand lever 15 outwards by means of the handle 21, so that the bolt 25 engages in the slot 24. As a result, by rotating the handle 21, a rotation of the tube 23 is possible, through which the eccentric 5 is rotated into the released position. Now it is possible to adjust the table top 3 both in height and in inclination, since the horizontal rod 4 is freely displaceable in the elongated hole 11 or the arcuate slot 13. As soon as the desired position of the table top 3 is reached, the operator rotates the handle 21 again, whereby the eccentric 5 is brought into its locked position. If the clamping force is not sufficient, an appropriate compensation can be created by adjusting the abutment 14. The operator can now push the hand lever 15 under the table top 3 without the clamping process being affected thereby.

Die Erfindung ist nicht auf das gezeigte Ausführungsbeispiel beschränkt, vielmehr ergeben im Rahmen der Erfindung vielfältige Abwandlungs- und Modifikationsmöglichkeiten.The invention is not limited to the exemplary embodiment shown, rather there are various modification and modification possibilities within the scope of the invention.
