Abstract

The leg (2) is assembled of a horizontal stand (4), an outer bar (6), an inner bar (8) and a gas pressurized spring (24) fixed between them and accommodated inside the inner bar (8). A flat longitudinal element (14) is accommodated inside the outer bar (6) at a short distance from its inner surface, facilitating the insertion of the inner bar (8) between the inner surface of the outer bar (6) and the flat element (14). The spring (24) is stationary joined to a horizontal bolt (28) located at the top of the flat element (14) and hung with a hook (24b) to a plate (26) fixed inside the lower end of the inner bar (8), facilitating an axial motion of the spring (24) within the set limits. When a locking screw (22) guided through both of the bars (6, 8) and the flat element (14) is loosened, the tabletop is lifted by the forces of the spring (24) and can be adjusted by tightening the screw (22) at the appropriate height.

Description

Die Erfindung betrifft eine höhenverstellbare Stütze für Möbel, insbesondere Tische, mit einem auf einem Untergrund abstellbaren ersten Stützelement, einem gegenüber dem ersten Stützelement höhenbewegbaren zweiten Stützelement (8) zur Halterung eines Abschnittes eines Möbels, insbesondere einer Tischplatte und einem Federelement, das das zweite Stützelement mit dem ersten Stützelement derart verbindet, dass es das zweite Stützelement gegenüber dem ersten Stützelement im Wesentlichen federnd vorspannt, und so angeordnet ist, dass sein mit dem ersten Stützelement verbundenes erstes Ende gegenüber dem Untergrund auf einem höheren Niveau als sein mit dem zweiten Stützelement verbundenes zweites Ende liegt.The invention relates to a height-adjustable support for furniture, in particular tables, with a settable on a substrate first support member, a respect to the first support member höhenbewegbaren second support member (8) for supporting a portion of a piece of furniture, in particular a table top and a spring element, the second support element is connected to the first support member such that it biases the second support member relative to the first support member substantially resilient, and is arranged so that its first end connected to the first support member to the ground at a higher level than its second support member connected to the second End lies.

Eine solche Stütze, wie sie beispielsweise aus der US 5,020,752 A1 bekannt ist, und somit auch die beiden Stützelemente weisen gewöhnlich einen länglichen Körper auf, der im wesentlichen aufrecht oder vertikal aufgestellt wird. Dabei bildet das erste Stützelement den unteren Teil der Stütze, welcher mit seinem unteren Ende direkt oder über einen Fuß auf einem Untergrund steht. Demgegenüber handelt es sich bei dem zweiten Stützelement um den oberen Teil der Stütze, an dessen oberem Ende ein Abschnitt des Möbels, im Falle eines Tisches die Tischplatte, befestigt ist. Gewöhnlich sind an einem Möbel mehrere, vorzugsweise drei oder vier, Stützen der zuvor beschriebenen Art vorgesehen, die dann um wesentlichen synchron höhenverstellbar sind. Derartige Stützen werden insbesondere für Tische mit höhenverstellbarer Tischplatte im Bürobereich verwendet. Um das zweite Stützelement und somit den von ihm getragenen Abschnitt des Möbels (beispielsweise Tischplatte) in der gewünschten Höhe zwischen einer oberen und einer unteren Endstellung zu arretieren, ist eine entsprechende Arretiereinrichtung vorgesehen. Das Federelement spannt das zweite Stützelement in die obere Endstellung vor, so dass bei gelöster Arretiereinrichtung das zweite Stützelement vom Federelement in die obere Endstellung bewegt wird.Such a support, as for example from the US 5,020,752 A1 is known, and thus also the two support members usually have an elongated body which is placed upright or vertically substantially. In this case, the first support member forms the lower part of the support, which stands with its lower end directly or over a foot on a substrate. In contrast, it is in the second support member to the upper part of the support, at the upper end of a portion of the furniture, in the case of a table, the table top, is attached. Usually several, preferably three or four, supports of the type described above are provided on a piece of furniture, which are then adjustable in height substantially synchronously. Such supports are used in particular for tables with height-adjustable tabletop in the office area. In order to lock the second support element and thus the portion of the furniture carried by it (for example table top) at the desired height between an upper and a lower end position, a corresponding locking device is provided. The spring element biases the second support element into the upper end position, so that when the locking device is released, the second support element is moved by the spring element into the upper end position.

Es ist Aufgabe der Erfindung, eine gegenüber dem Stand der Technik einfachere Konstruktion vorzuschlagen, die in effektiverer Weise die gewünschte federnde Vorspannung des zweiten Stützelementes gegenüber dem ersten Stützelement ermöglicht.It is an object of the invention to provide a comparison with the prior art simpler construction, which allows in a more effective manner, the desired resilient bias of the second support member relative to the first support member.

Diese Aufgabe wird gelöst durch eine höhenverstellbare Stütze für Möbel, insbesondere Tische, mit einem auf einem Untergrund abstellbaren ersten Stützelement, einem gegenüber dem ersten Stützelement höhenbewegbaren zweiten Stützelement zur Halterung eines Abschnittes eines Möbels, insbesondere einer Tischplatte und einem Federelement, das das zweite Stützelement mit dem ersten Stützelement derart verbindet, dass es das zweite Stützelement gegenüber dem ersten Stützelement im Wesentlichen federnd vorspannt, und so angeordnet ist, dass sein mit dem ersten Stützelement verbundenes erstes Ende gegenüber dem Untergrund auf einem höheren Niveau als sein mit dem zweiten Stützelement verbundenes zweites Ende liegt, dadurch gekennzeichnet, dass das erste Stützelement einen ersten Abschnitt und einen vom ersten Abschnitt beabstandeten, neben diesem angeordneten und sich im Wesentlichen in Längsrichtung des ersten Stützelementes länglich erstreckenden zweiten Abschnitt aufweist, das zweite Stützelement mit einem Abschnitt zwischen den ersten und zweiten Abschnitten des ersten Stützelements liegt und das erste Ende des Federelementes mit dem zweiten Abschnitt des ersten Stützelementes verbunden ist.This object is achieved by a height-adjustable support for furniture, in particular tables, with a settable on a substrate first support element, a höhenbewegbaren relative to the first support member second support member for supporting a portion of a piece of furniture, in particular a table top and a spring element, which with the second support member the first support member connects such that it biases the second support member relative to the first support member substantially resilient, and is arranged so that its first end connected to the first support member relative to the ground at a higher level than its second end connected to the second support member is located, characterized in that the first support member on a first portion and a spaced from the first portion, arranged next to this and extending substantially in the longitudinal direction of the first support member longitudinally extending second portion has the second support member with a portion between the first and second portions of the first support member is located and the first end of the spring element is connected to the second portion of the first support element.

Die Erfindung bietet eine einfache, jedoch wirkungsvolle und zugleich preiswerte Konstruktion für eine höhenverstellbare Stütze für Möbel, bei welcher das einen Abschnitt des Möbels tragende zweite Stützelement einer Vorspannung durch ein Federelement unterworfen wird, und lässt dabei in besonders geschickter Weise eine verdeckte und ihre Funktion nicht beeinträchtigende Anordnung des Federelementes zu. Außerdem wird mit Hilfe der erfindungsgemäßen Konstruktion bei Vorspannung des zweiten Stützelementes in dessen obere Endstellung ein unerwünschtes seitliches Auswandern des Federelementes vermieden, da das Federelement auf Zug beansprucht wird; besondere konstruktive Maßnahmen, um das Federelement zu führen und in Flucht zu halten, sind nicht notwendig.The invention provides a simple, yet effective and at the same time inexpensive construction for a height-adjustable support for furniture, in which a portion of the furniture supporting second support element is subjected to a bias by a spring element, and leaves in a particularly clever way a covert and their function not impairing arrangement of the spring element to. In addition, an undesirable lateral migration of the spring element is avoided with the help of the construction according to the invention in biasing the second support member in its upper end position, since the spring element is subjected to train; special design measures to guide the spring element and keep it in flight, are not necessary.

Bevorzugte Ausführungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Preferred embodiments of the invention are indicated in the dependent claims.

So sollte das Federelement auf Zug vorgespannt sein, wodurch das zweite Stützelement in die obere Endstellung vorgespannt wird.Thus, the spring element should be biased to train, whereby the second support member is biased in the upper end position.

Zweckmäßigerweise greift das erste Ende des Federelementes an einem oberen Abschnitt des ersten Stützelementes und das zweite Ende des Federelementes an einem gegenüber dem oberen Abschnitt des ersten Stützelementes tiefer liegenden unteren Abschnitt des zweiten Stützelementes an.Conveniently, the first end of the spring element engages an upper portion of the first support member and the second end of the spring member at a lower relative to the upper portion of the first support member lower portion of the second support member.

Gewöhnlich ist noch eine Feststelleinrichtung zum wahlweisen Fixieren des zweiten Stützelementes gegenüber dem ersten Stützelement vorgesehen. Bei einer Weiterbildung der zuletzt beschriebenen bevorzugten Ausführung weist die Feststelleinrichtung Mittel zum Erzeugen eines Reibschlusses zwischen den ersten und zweiten Abschnitten des ersten Stützelementes und dem zweiten Stützelement auf. Somit wird zum Feststellen das zweite Stützelement mit einem Abschnitt zwischen den ersten und zweiten Abschnitten des ersten Stützelementes eingeklemmt. Hierzu können vorzugsweise die ersten und zweiten Abschnitte des ersten Stützelementes jeweils eine Bohrung und der dazwischen liegende Abschnitt des zweiten Stützelementes ein sich in Bewegungsrichtung erstreckendes Langloch aufweisen und ist das Mittel zum Erzeugen des Reibschlusses eine Schraube, die sich durch die Bohrungen und das Langloch erstreckt. Die Schraube kann sich in Schraubeingriff mit dem ersten oder dem zweiten Abschnitt des ersten Stützelementes befinden, je nachdem welcher dieser beiden Abschnitte vom Kopf der Schraube entfernter liegt. Alternativ ist es aber auch denkbar, die Schraube mit einer Mutter zu sichern.Usually, a locking device for selectively fixing the second support member relative to the first support member is provided. In a development of the last-described preferred embodiment, the locking device has means for generating a frictional connection between the first and second sections of the first support element and the second support element. Thus, for fixing, the second support member is provided with a portion between the first and second portions of the first support member trapped. For this purpose, preferably, the first and second portions of the first support member each have a bore and the intermediate portion of the second support member extending in the direction of movement slot and the means for generating the frictional engagement is a screw which extends through the holes and the slot. The screw may be in screw engagement with the first or second portion of the first support member depending on which of these two portions is more remote from the head of the screw. Alternatively, it is also conceivable to secure the screw with a nut.

Gewöhnlich weisen die ersten und zweiten Stützelemente teleskopierbar ineinander geführte Rohre auf, von denen vorzugsweise das Rohr des zweiten Stützelementes im Rohr des ersten Stützelementes geführt sein sollte.Usually, the first and second support members telescopically guided into each other tubes, of which preferably the tube of the second support member should be performed in the tube of the first support element.

Vorzugsweise sollte der erste Abschnitt des ersten Stützelementes als Außenrohr und dessen zweiter Abschnitt als innenliegende, sich im wesentlichen in Längsrichtung des Stützelementes erstreckende Leiste ausgebildet sein, so dass das Rohr des zweiten Stützelementes mit einem Abschnitt zwischen dem Außenrohr des ersten Stützelementes und der innenliegenden Leiste einklemmbar ist.Preferably, the first portion of the first support member should be formed as an outer tube and the second portion as an inner, extending substantially in the longitudinal direction of the support member bar, so that the tube of the second support member with a portion between the outer tube of the first support member and the inner bar clamped is.

Zweckmäßigerweise kann das zweite Ende des Federelementes an einem Verbindungselement verankert sein, das am unteren Ende des Rohres des zweiten Stützelementes anliegt oder angeordnet ist.Conveniently, the second end of the spring element can be anchored to a connecting element, which rests or is arranged at the lower end of the tube of the second support element.

Nachfolgend wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand der beiliegenden Zeichnungen näher erläutert. Es zeigen:

Figur 2
die wesentlichen Einzelteile der Stütze von Figur 1 in demontierter bzw. auseinandergezogener, teilweise geschnittener, perspektivischer Darstellung.
Hereinafter, a preferred embodiment of the invention will be explained in more detail with reference to the accompanying drawings. Show it:
FIG. 1
a preferred embodiment of a height-adjustable support in a partially sectioned perspective view; and
FIG. 2
the essential items of the prop of FIG. 1 in disassembled or exploded, partially cut, perspective view.

Die in den Figuren 1 und 2 dargestellte höhenverstellbare Stütze 2 bildet vorzugsweise einen Teil eines Schreibtisches und trägt die zugehörige Tischplatte. Gewöhnlich sind mindestens zwei solcher Stützen angeordnet, und zwar vorzugsweise eine Stütze an der rechten Seite und eine weitere Stütze an der linken Seite des Tisches. Gleichwohl ist es aber auch denkbar, die dargestellte Stütze 2 für andere Möbel zu verwenden, bei denen eine Höhenverstellbarkeit gefordert ist.The in the Figures 1 and 2 illustrated height-adjustable support 2 preferably forms part of a desk and carries the associated tabletop. Usually at least two such supports are arranged, preferably one support on the right side and another support on the left side of the table. However, it is also conceivable to use the illustrated support 2 for other furniture in which a height adjustment is required.

Wie Figur 1 erkennen lässt, weist die dargestellte Stütze 2 ein horizontal ausgerichtetes Fußelement 4 auf, das der Stütze 2 eine ausreichende Standfestigkeit gibt, damit die Stütze 2 sicher auf einem nicht dargestellten Untergrund stehen kann.As FIG. 1 can recognize, the illustrated support 2 has a horizontally oriented foot member 4, which gives the support 2 sufficient stability, so that the support 2 can stand securely on a substrate, not shown.

Die Stütze 2 weist ein unteres erstes rohrförmiges Stützelement 6 auf, das mit seinem unteren Ende 6a etwa rechtwinklig auf dem Fußelement 4 befestigt ist. Das erste rohrförmige Stützelement 6 ist an seinem oberen Ende 6b offen, in das ein oberes zweites rohrförmiges Stützelement 8 gesteckt ist, so dass das untere Ende 8a des zweiten rohrförmigen Stützelementes 8 innerhalb des ersten rohrförmigen Stützelements 6 liegt. Das obere Ende 8b des zweiten rohrförmigen Stützelementes 8 befindet sich außerhalb des ersten rohrförmigen Stützelementes 6 und liegt oberhalb dessen oberen Endes 6b. Im dargestellten Ausführungsbeispiel ist am oberen Ende 8b des zweiten rohrförmigen Stützelementes 8 ein Beschlag 10 zur Halterung einer Tischplatte u.dgl. befestigt.The support 2 has a lower first tubular support element 6, which is fastened with its lower end 6 a approximately at right angles to the base element 4. The first tubular support member 6 is open at its upper end 6 b, into which an upper second tubular support member 8 is inserted, so that the lower end 8 a of the second tubular support member 8 is within the first tubular support member 6. The upper end 8b of the second tubular support member 8 is located outside the first tubular support member 6 and lies above the upper end 6b thereof. In the illustrated embodiment, a fitting 10 for holding a table top and the like at the upper end 8b of the second tubular support member 8. attached.

Wie Figur 1 ferner erkennen lässt, sind im aufgestellten Zustand des dargestellten Ausführungsbeispiels die ersten und zweiten rohrförmigen Stützelemente 6, 8 etwa vertikal oder aufrecht angeordnet. Denkbar wäre aber auch eine gegenüber dem Untergrund geneigte Anordnung. Das obere zweite rohrförmige Stützelement 8 ist etwa koaxial zum unteren ersten rohrförmigen Stützelement 6 und gegenüber diesem in Längsrichtung verschiebbar angeordnet. Somit bilden die ineinander gesteckten ersten und zweiten rohrförmigen Stützelemente 6, 8 eine Teleskopanordnung zur Höhenverstellung, wobei gegenüber dem nicht dargestellten Untergrund das untere erste rohrförmige Stützelement 6 stationär und das obere zweite rohrförmige Stützelement 8 beweglich ist. Dadurch, dass das obere zweite rohrförmige Stützelement 8 über einen begrenzten Weg wahlweise herausgezogen und in dieses hineingeschoben werden kann, ist das obere zweite rohrförmige Stützelement 8 zwischen einer unteren Endstellung und einer oberen Endstellung höhenverstellbar.As FIG. 1 can also be seen, the first and second tubular support members 6, 8 are arranged approximately vertically or upright in the erected state of the illustrated embodiment. It would also be conceivable, however, an arrangement inclined to the ground. The upper second tubular support member 8 is arranged approximately coaxially with the lower first tubular support member 6 and against this longitudinally displaceable. Thus, the nested first and second tubular support members 6, 8 form a telescopic assembly for height adjustment, with respect to the substrate, not shown, the lower first tubular support member 6 stationary and the upper second tubular support member 8 is movable. Characterized in that the upper second tubular support member 8 can optionally be pulled out over a limited way and pushed into this, the upper second tubular support member 8 height adjustable between a lower end position and an upper end position.

Wie insbesondere Figur 2 erkennen lässt, weist das untere erste Stützelement 6 ein Rohr 12 und eine Leiste 14 auf, die innerhalb des Rohres 12 angeordnet ist und sich in dessen Längsrichtung erstreckt. Mit ihrem unteren Ende 14a ist die Leiste 14 im Bereich des unteren Endes 6a des ersten Stützelementes 6 mit Hilfe einer Schraube 16 am Rohr 12 befestigt, während das obere Ende 14b der Leiste 14 aus dem Rohr 12 herausragt und somit oberhalb des oberen Endes 6b des ersten Stützelementes 6 liegt.In particular FIG. 2 can recognize, the lower first support member 6, a tube 12 and a bar 14 which is disposed within the tube 12 and extending in the longitudinal direction thereof. With its lower end 14a, the bar 14 is fixed in the region of the lower end 6a of the first support member 6 by means of a screw 16 on the tube 12, while the upper end 14b of the bar 14 protrudes from the tube 12 and thus above the upper end 6b of the first support element 6 is located.

Die Leiste 14 ist innerhalb des Rohres 12 des ersten Stützelementes 6 in einem solchen Abstand von der Innenwandung des Rohres 12 angeordnet, dass das obere zweite rohrförmige Stützelement 8 mit seinem benachbarten Abschnitt zwischen der Innenwandung des Rohres 12 des ersten Stützelementes 6 und der Leiste 14 liegt. Dabei kann die Anordnung so getroffen sein, dass die Außenwandung des zweiten rohrförmigen Stützelementes 8 an der Innenwandung des Rohres 12 des ersten Stützelementes 6 und die Innenwandung des zweiten rohrförmigen Stützelementes 8 an der Leiste 14 leicht anliegen kann, wobei allerdings noch so viel Spiel vorhanden sein muss, damit das zweite rohrförmige Stützelement 8 gegenüber dem ersten rohrförmigen Stützelement 6 teleskopierbar bewegt werden kann.The strip 14 is disposed within the tube 12 of the first support member 6 at such a distance from the inner wall of the tube 12 that the upper second tubular support member 8 is located with its adjacent portion between the inner wall of the tube 12 of the first support member 6 and the bar 14 , In this case, the arrangement may be such that the outer wall of the second tubular support member 8 on the inner wall of the tube 12 of the first support member 6 and the inner wall of the second tubular support member 8 may rest against the bar 14, but still so much game be present must, so that the second tubular support member 8 relative to the first tubular support member 6 can be moved telescopically.

Wie insbesondere Figur 2 ferner erkennen lässt, ist zwischen dem unteren Ende 6a und dem oberen Ende 6b an einer Stelle im Rohr 12 des ersten Stützelementes 6 eine Bohrung 18 ausgebildet. Auf gleicher Höhe und mit dieser Bohrung 18 fluchtend ist in der Leiste 14 ebenfalls eine Bohrung vorgesehen, die jedoch in den Figuren nicht erkennbar ist. Ferner ist auf gleicher Höhe im zweiten rohrförmigen Stützelement 8 ein Langloch 20 ausgebildet, das sich in Längsrichtung des zweiten Stützelementes 8 erstreckt. Durch die Bohrung 18 im Rohr 12 des ersten Stützelementes 6, das Langloch 20 im zweiten Stützelement 8 und die Bohrung in der Leiste 14 ist eine Arretierschraube 22 gesteckt, die bei Festziehen einen Reibschluss zwischen dem Rohr 12 und der Leiste 14 des ersten Stützelement 6 einerseits und dem zweiten Stützelement 8 andererseits herstellt. Zur Erzielung eines Schraubeingriffes ist die in der Leiste 14 vorgesehene Bohrung als Gewindebohrung ausgebildet; alternativ ist es aber auch beispielsweise denkbar, die Bohrung in der Leiste 14 als Durchgangsbohrung vorzusehen und an der rückwärtigen Seite der Leiste 14 eine Mutter anzuschweißen. Demnach bildet die Arretierschraube 22 eine Feststelleinrichtung, um das zweite Stützelement 8 in einer gewünschten Höhe zwischen der oberen Endstellung und der unteren Endstellung gegenüber dem ersten Stützelement 6 arretieren zu können. Dabei wird der Hubweg für die Höhenverstellung zwischen der oberen Endstellung der unteren Endstellung durch die Länge des Langloches 20 im zweiten Stützelement 8 definiert.In particular FIG. 2 can also be seen, a bore 18 is formed between the lower end 6a and the upper end 6b at a location in the tube 12 of the first support member 6. At the same height and with this bore 18 is aligned in the bar 14 also provided a bore, which is not visible in the figures. Further, a slot 20 is formed at the same height in the second tubular support member 8, which extends in the longitudinal direction of the second support member 8. Through the bore 18 in the tube 12 of the first support member 6, the slot 20 in the second support member 8 and the bore in the bar 14, a locking screw 22 is inserted, the tightening a frictional engagement between the tube 12 and the bar 14 of the first support member 6 on the one hand and the second support member 8 on the other hand. To achieve a screw engagement provided in the bar 14 hole is formed as a threaded hole; Alternatively, however, it is also conceivable, for example to provide the bore in the strip 14 as a through hole and to weld a nut on the rear side of the bar 14. Accordingly, the locking screw 22 forms a locking device to lock the second support member 8 at a desired height between the upper end position and the lower end position relative to the first support member 6 can. The stroke for the height adjustment between the upper end position of the lower end position is defined by the length of the elongated hole 20 in the second support member 8.

Innerhalb des zweiten rohrförmigen Stützelementes 8 erstreckt sich nicht nur die Leiste 14 des ersten Stützelementes 6, sondern zusätzlich auch noch eine Feder 24 in Längsrichtung der ersten und zweiten rohrförmigen Stützelemente 6, 8. Die Feder 24 weist ein unteres hakenförmiges Ende 24b auf, das an einem querliegenden und somit horizontal angeordneten Plättchen 26 verankert ist, welches am unteren Ende 8a des zweiten rohrförmigen Stützelementes 8 anliegt oder daran befestigt ist, jedoch weder mit dem Rohr 12 noch mit der Leiste 14 in Verbindung steht, sondern gegenüber dem ersten Stützelement 6 beweglich ist. Ferner weist die Feder 24 ein hakenförmiges oberes Ende 24a auf, das an einem Querbolzen 28 verankert ist, welcher am oberen Ende 14b der Leiste 14 befestigt ist.Within the second tubular support member 8, not only the strip 14 of the first support member 6 extends, but in addition also a spring 24 in the longitudinal direction of the first and second tubular support members 6, 8. The spring 24 has a lower hook-shaped end 24 b, the at a transverse and thus horizontally arranged plate 26 is anchored, which abuts the lower end 8a of the second tubular support member 8 or is attached thereto, but is not in communication with the tube 12 and the bar 14, but is movable relative to the first support member 6 , Further, the spring 24 has a hook-shaped upper end 24a which is anchored to a transverse pin 28 which is secured to the upper end 14b of the strip 14.

Im dargestellten Ausführungsbeispiel ist die Feder 24 als Zugfeder ausgebildet. Da sie mit ihrem oberen Ende 24a am oberen Ende 14b der Leiste 14 befestigt ist, welche Bestandteil des stationär angeordneten ersten Stützelementes 6 ist, befindet sich das obere Ende 24a der Feder 24 ebenfalls in einer gegenüber dem Untergrund fixierten Position. Demgegenüber ist das untere Ende 24b der Feder 24 beweglich, da es am unteren Ende 8a des in der Höhe beweglichen zweiten Stützelementes 8 verankert ist. Da eine Zugfeder stets die Eigenschaft hat, ihre kürzeste Länge einzunehmen, hat dies zur Folge, dass bei gelöster Arretierschraube 22 die Feder 24 das zweite Stützelement 8 nach oben zieht, dadurch der Abstand zwischen dem unteren Ende 8a des zweiten Stützelementes 8 und dem oberen Ende 14b der Leiste 14 des ersten Stützelementes 6 auf einen Mindestwert verkürzt wird, somit das zweite Stützelement 8 in die obere Endstellung federnd vorgespannt wird und dabei die am Beschlag 10 befestigte (in den Figuren nicht dargestellte) Tischplatte auf die größtmögliche Höhe gegenüber dem Untergrund verbracht wird. Soll dagegen die Höhe reduziert werden, muss gegen die Spannung der Feder 24 entsprechend Druck auf das bewegliche zweite Stützelement 8 ausgeübt werden, um dieses in Richtung auf das untere Ende 6a des ersten Stützelementes 6 zu bewegen, wobei dann durch Festziehen der Arretierschraube 22 die Stütze 2 auf die gewünschte Höhe fixiert wird.In the illustrated embodiment, the spring 24 is formed as a tension spring. Since it is attached with its upper end 24a at the upper end 14b of the bar 14, which is part of the stationarily arranged first support member 6, the upper end 24a of the spring 24 is also in a fixed position relative to the ground. In contrast, the lower end 24b of the spring 24 is movable, since it is anchored at the lower end 8a of the second support element 8 which is movable in height. Since a tension spring always has the property to take their shortest length, this has the consequence that when dissolved locking screw 22, the spring 24, the second support member 8 pulls up, thereby the distance between the lower end 8a of the second support member 8 and the upper end 14b of the bar 14 of the first support member 6 is shortened to a minimum value, thus the second support member 8 is resiliently biased in the upper end position and thereby attached to the fitting 10 (not shown in the figures) table top is spent on the maximum height to the ground , If, on the other hand, the height is to be reduced, it must be against the tension the spring 24 are applied according to pressure on the movable second support member 8 to move it in the direction of the lower end 6a of the first support member 6, in which case by tightening the locking screw 22, the support 2 is fixed to the desired height.
