Weiterhin weist das innere Stützelement 14 in seiner vorderen Breitseite 18 eine Längsöffnung 20 mit quer zur Teleskopierrichtung gegenüberliegend und entgegengesetzt paarig ausgebildeten Rastaussparungen auf, von denen nur einige mit der Bezugszahl 22 gekennzeichnet sind. Darüber hinaus weist das innere Stützelement 14 an seinen beiden Schmalseiten, von denen nur eine zu sehen und mit 21 gekennzeichnet ist, im Bereich beider Enden der Längsöffnungen quer zur Teleskopierrichtung gegenüberliegend ausgebildete Öffnungen 24, 26, 28 und 30 auf, in die von der Innenseite des inneren Stützelements 14 jeweils ein Kugelwälzlager 32, 34, 36 und 38 einklippsbar ist. Besagte Kugelwälzlager dienen zur Führung des inneren Stützelements 14 in dem äußeren Stützelement 12.Furthermore, the inner support member 14 in its front broad side 18 on a longitudinal opening 20 with opposite to the telescoping opposite and oppositely paired locking recesses, of which only a few are designated by the reference numeral 22. In addition, the inner support member 14 at its two narrow sides, of which only one is seen and marked 21, in the region of both ends of the longitudinal openings transverse to the telescoping oppositely formed openings 24, 26, 28 and 30, in the from the inside of the inner support member 14 is a ball bearing 32, 34, 36 and 38 einklippsbar. Said ball bearings serve to guide the inner support member 14 in the outer support member 12th

Wie sich unter Hinzuziehung der Figuren 2 bis 5 ergibt, erstreckt sich im Inneren des inneren Stützelements 14 in Längsrichtung desselben ein Außenrohr 40 aus Kunststoff, dessen oberes Ende 42 in einer oben geschlossenen, an dem inneren Stützelement, genauer gesagt, an der hinteren Breitseite 44, lösbar befestigten oberen Aufnahme 46 steckt und dessen unteres Ende 48 sich auf einem Rand 50 einer Öffnung 52 in der Unterseite einer an dem inneren Stützelement 14 lösbar befestigten Aufnahme 54 abstützt. Ein Innenrohr 56 aus Aluminium ist in das Außenrohr 40 geschoben. Es erstreckt sich durch die untere Aufnahme 54 und stützt sich mit seinem unteren Ende 58 auf einer Bodenplatte 60 in dem äußeren Stützelement 12 ab. Das Innenrohr 56 ist kürzer als das Außenrohr 40. Über dem Innenrohr 56 ist eine Druckfeder (Schraubenfeder) 62 in das Außenrohr 40 geschoben. Besagte Druckfeder 62 stützt sich mit ihrem unteren Ende 64 auf dem oberen Ende 59 des Innenrohres 56 ab. Ihr oberes Ende 66 steckt in der oberen Aufnahme 46, so dass sie zwischen dem Innenrohr 56 und der oberen Aufnahme 46 eingespannt ist. Durch diese Einspannung wird das innere Stützelement 14 in seine obere Endstellung vorgespannt.How to join in the FIGS. 2 to 5 results in the interior of the inner support member 14 in the longitudinal direction of the same an outer tube 40 made of plastic, the upper end 42 in an upwardly closed, on the inner support member, more precisely, on the rear broad side 44, releasably secured upper receptacle 46 inserted and its lower end 48 is supported on an edge 50 of an opening 52 in the bottom of a releasably secured to the inner support member 14 receptacle 54. An inner tube 56 made of aluminum is pushed into the outer tube 40. It extends through the lower receptacle 54 and is supported by its lower end 58 on a bottom plate 60 in the outer support member 12 from. The inner tube 56 is shorter than the outer tube 40. Above the inner tube 56, a compression spring (coil spring) 62 is pushed into the outer tube 40. Said compression spring 62 is supported with its lower end 64 on the upper end 59 of the inner tube 56. Its upper end 66 is in the upper receptacle 46, so that it is clamped between the inner tube 56 and the upper receptacle 46. By this clamping the inner support member 14 is biased in its upper end position.

Wie sich anhand der Figuren 2, 4 und 5 ergibt, weist die hintere Breitseite 44 des inneren Stützelements 14 Montageöffnungen 68 zur werkzeuglosen lösbaren Befestigung der Aufnahmen 46 und 54 durch Einsetzen und Zur-Seite-Schieben von an den Rückseiten der Aufnahmen angeordneten pilzförmigen Befestigungselementen 70 auf.As reflected by the Figures 2 . 4 and 5 shows, the rear broad side 44 of the inner support member 14 mounting holes 68 for tool-free releasably securing the receptacles 46 and 54 by inserting and Zur-side pushing arranged on the backs of the receptacles mushroom-shaped fasteners 70 on.

Wie sich anhand der Figuren 1, 3 und 4 ergibt, sind im oberen Bereich der hinteren Breitseite 44 des inneren Stützelements 14 zwei Schenkel 72 zur Anbindung an eine Traverse (nicht gezeigt) vorgesehen. Besagte Schenkel 72 sind im Abstand zueinander angeordnet und verlaufen parallel zueinander senkrecht zur hinteren Breitseite 44.As reflected by the FIGS. 1 . 3 and 4 results, 14 two legs 72 are provided for connection to a cross member (not shown) in the upper region of the rear broad side 44 of the inner support member. Said legs 72 are arranged at a distance from each other and parallel to each other perpendicular to the rear broad side 44th

Wie sich anhand der Figur 3 ergibt, wird das innere Stützelement 14 in dem äußeren Stützelement 12 nach oben geschoben, wenn der Druckfeder 62 ermöglicht wird, sich zu "entspannen". Die Druckfeder 62 zieht dabei die untere Aufnahme 54 gemeinsam mit dem inneren Stützelement 14 nach oben. Das heißt also, dass die untere Aufnahme 54 über das Innenrohr 56 nach oben geschoben wird.As reflected by the FIG. 3 results, the inner support member 14 is pushed in the outer support member 12 upwards when the compression spring 62 is allowed to "relax". The compression spring 62 pulls the lower receptacle 54 together with the inner support member 14 upwards. This means that the lower receptacle 54 is pushed over the inner tube 56 upwards.

Im Übrigen wird nicht nur die komplette höhenverstellbare Stütze, sondern auch die Federeinrichtung alleine beansprucht.Incidentally, not only the complete height-adjustable support, but also the spring device is claimed alone.

Die in der vorstehenden Beschreibung, in den Zeichnungen sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in den beliebigen Kombinationen für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen wesentlich sein.The features of the invention disclosed in the foregoing description, in the drawings and in the claims may be essential both individually and in any desired combinations for the realization of the invention in its various embodiments.
