    • Fig. 1 zeigt eine teleskopische Vorrichtung mit einer als Rohr ausgebildeten äußeren Stange 5 und einer in diese eingefügten, ebenfalls als Rohr ausgebildeten inneren Stange 6. Im Bereich des Endes der äußeren Stange 5, durch das die innere Stange 6 geführt ist, ist ein Gurt 2 an der äußeren Stange festgemacht, wobei der Gurt in das Innere der äußeren Stange 5 verläuft, um eine Umlenkeinrichtung 1, die eine am inneren bzw. hier auch unteren Ende der inneren Stange 6 angebrachte Umlenkrolle 26 aufweist, wieder hinauf in Richtung freies Ende der äußeren Stange 5 und von dort durch einen Gurtstrammer 36 geführt.Fig. 1 shows a telescopic device with a formed as a tube outer rod 5 and one in this inserted inner rod, also designed as a tube 6. In the area of the end of the outer rod 5 through which the inner rod 6 is guided, a belt 2 on the outer Rod fastened with the strap inside the outer Rod 5 extends to a deflection device 1, the one on inner or lower end of the inner rod 6 attached deflection roller 26, up again in the direction free end of the outer rod 5 and from there through a belt tensioner 36 out.

    Der Gurtstrammer 36 kann herkömmlicher Bauart, beispielsweise ein Ratschenstrammer, sein. Dieser weist eine Trommel mit einem die Trommelachse 13 enthaltenden Schlitz auf, in den der Gurt eingelegt werden kann. In einer Stellung des Gurtstrammerhebels 7 kann der Gurt über erhebliche Längen von Hand durch den Schlitz gezogen werden, womit bei der dargestellten Ausführungsform die innere Stange 6 in entsprechender Länge aus der äußeren Stange 5 herausgehoben wird. Im dargestellten Beispiel tritt ein Flaschenzugeffekt von 1:2 auf, der auch im Sinne einer Verringerung der für das manuelle Ziehen am Gurt benötigten Kraft wirkt. Sobald die Endstellung erreicht oder nahezu erreicht ist, beispielsweise unter einer abzustützenden Schalung, wird mit einer Ratschenbewegung der Hebel 7 in Tätigkeit gesetzt, wodurch der Gurt, wie aus Fig. 1 ersichtlich, auf sich selbst geklemmt wird und über eine geringe Strecke zu der Erzeugung des erforderlichen Anpreßdrucks gespannt bzw. festgezurrt werden kann. Nach Erreichen der Endstellung wird durch Umklappen des Hebels 7 der Gurt in dieser Stellung arretiert.The belt tensioner 36 can be of conventional design, for example a ratchet tight. This one Drum with a slot containing the drum axis 13 in which the belt can be inserted. In one position the belt pretensioner lever 7, the belt can be considerable Lengths are pulled by hand through the slot, with which the illustrated embodiment, the inner rod 6 in appropriate length lifted out of the outer rod 5 becomes. In the example shown, a pulley effect occurs from 1: 2 on, which also means reducing the for the manual pull on the belt required force acts. As soon as the end position has been reached or almost reached, for example under a formwork to be supported, with a ratchet movement of lever 7 is activated, whereby the belt, as shown in Fig. 1, on itself itself is clamped and over a short distance to the Generation of the required contact pressure can be lashed down. After reaching the end position by folding the lever 7 of the belt in this position locked.

    Ein Kasten 29 nimmt überschüssige Gurtlänge auf. DerA box 29 takes up excess belt length. The

    Gurt kann mit einem Federwerk aufgerollt werden.Belt can be rolled up with a spring mechanism.

    Eine an sich bekannte Kraftanzeige 21, die den festgezurrten Gurt federbelastet, wirkt gleichzeitig als elastischer Puffer zur Aufnahme etwaiger zusätzlicher Gurtlänge, die infolge einer Streckung des Gurtes unter der Einwirkung der Last zustandekommen kann.A power indicator 21 known per se, which the lashed down Belt spring-loaded, acts as elastic at the same time Buffer to accommodate any additional belt length, the result of stretching the belt under the action the load can come about.

    Die Umlenkrolle 26 ist bei dieser Ausführungsform, wie im Vergleich mit Fig. 2 zu sehen, mittels eines umsteckbaren Achszapfens 30 von der inneren Stange auf die äußere Stange umsteckbar. Wenn gleichzeitig die Befestigung des befestigten Endes 20 des Gurtes 2 an der inneren Stange 6 anstatt an der äußeren Stange 5 vorgenommen wird, eignet sich die gegenständliche Vorrichtung zum Einspannen von Gegenständen, weil dann unter der Wirkung einer Gurtstraffung die beiden teleskopierenden Teile 5 und 6 gegeneinander bewegt werden.The deflection roller 26 is in this embodiment, as seen in comparison with Fig. 2, by means of a removable Axle journal 30 from the inner rod to the outer rod changeable. If at the same time the attachment of the attached End 20 of the belt 2 on the inner rod 6 instead of the outer rod 5 is made, the subject is suitable Device for clamping objects, because then, under the effect of a belt tension, the two telescopic parts 5 and 6 are moved against each other.

    Die Welle 27 ist mittels eines Federnockens 31 in einem Schlitz der inneren Stange 6 festgelegt und kann gegen den Widerstand dieses Federnockens mit der Umlenkrolle herausgezogen werden.The shaft 27 is in one by means of a spring cam 31 Slit of the inner rod 6 is fixed and can against the Pull out the resistance of this spring cam with the deflection roller become.

    Eine gleiche Klemmwirkung zwischen dem Fuß der äußeren Stange 5 und dem Fuß der inneren Stange 6 kann erzielt werden, wenn die innere Stange durch die äußere Stange nach unten (bei Sicht gemäß Fig. 2) durchgeschoben wird und dabei gegenüber der äußeren Stange so liegt wie in der kombinierten Fig. 2 und 2a. Der Gurt ist dabei natürlich (wie in Fig. 1) an der äußeren Stange einzuhängen.An equal clamping effect between the foot of the outer Rod 5 and the foot of the inner rod 6 can be achieved when the inner rod goes through the outer rod is pushed through (as seen in FIG. 2) and thereby opposite the outer rod as in the combined one 2 and 2a. The belt is natural (as in Fig. 1) Hang on the outer rod.

    Die äußere Stange weist ferner ein Fußteil 4 aus biegesteifen Platten auf, das über elastische Auflagekörper 3 auf einem Boden aufliegen kann.The outer rod also has a foot part 4 made of rigid Plates on that on elastic support body 3 can rest on a floor.

    Fig. 3 zeigt eine Ausführungsform, bei welcher der Gurtstrammer 36 mit einer Klemmvorrichtung 8 mit Keilen 14 und 15 zusammenwirkt, die in der Schließstellung des Gurtstrammers (Hebel 7 hin in etwa vertikaler Stellung) vom Gurtstrammer frei sind und unter Federbelastung sich zwischen innerer und äußerer Stange 6 bzw. 5 verkeilen und so eine Lagefestlegung der beiden Stangen zueinander bewirken, die von den Haltekräften des Gurts unabhängig ist. Der Gurt könnte dann im Prinzip durchtrennt werden, ohne daß dies von Einfluß auf die Relativposition der beiden Stangen 5 und 6 ist.Fig. 3 shows an embodiment in which the Belt tensioner 36 with a clamping device 8 with wedges 14 and 15 cooperates in the closed position of the belt tensioner (Lever 7 towards the vertical position) from Belt tensioners are free and under spring load between themselves wedge inner and outer rods 6 and 5 and so cause the two rods to be fixed in position, which is independent of the belt holding forces. The belt could then in principle be severed without this from Influence on the relative position of the two rods 5 and 6 is.

    Wird der Hebel 7 aus dieser Schließstellung umgelegt, so hebt eine entsprechende Nase 70 dieses Hebels die Keile 14 und 15 aus ihrer Klemmstellung an, so daß dann die beiden Stangen 5 und 6 insoweit in ihrer Relativbewegung frei sind.If lever 7 is flipped from this closed position, a corresponding nose 70 of this lever lifts the wedges 14 and 15 from their clamping position, so that the two Bars 5 and 6 are so far free in their relative movement.

    Die gurtlängenkompensierende Kraftmeßeinrichtung 21 wirkt hier zwischen dem Umlenkteil 1 und der inneren Stange 6.The belt length compensating force measuring device 21 acts here between the deflection part 1 and the inner rod 6.

    Fig. 4 zeigt die Klemmeinrichtung 8 der Fig. 3 in Lösestellung.Fig. 4 shows the clamping device 8 of Fig. 3 in the release position.

    Gemäß Fig. 5 preßt ein am Hebel 7 vorgesehener, um die Trommelachse 13 verstellbarer mittels Riegel 12 festzusetzender, Exzenter 9 über eine Platte 10 der Klemmvorrichtung, in einer anderen Möglichkeit auch direkt, die innere Stange 6. In anderen Stellungen des Hebels 7 ist die Klemmeinrichtung 8 gelöst.5 presses a provided on the lever 7 to the Drum axis 13 adjustable by means of latch 12, Eccentric 9 via a plate 10 of the clamping device, in another possibility also directly, the inner rod 6. In other positions of the lever 7 is the clamping device 8 solved.

    Fig. 6 zeigt eine mögliche Ausführungsform für die Teile 15 bzw. 14 und 10. Sie wirken nach dieser Ausführungsform mit entsprechenden Schrägflächen nur gegen komplementäre Schrägflächen im Eckbereich des Querschnitts der inneren Stange 6. Durch die dadurch bewirkte keilförmige Anlage zwischen diesen Teilen und der Stange 6 wird eine verstärkte Klemmwirkung erreicht.Fig. 6 shows a possible embodiment for the Parts 15 or 14 and 10. They work according to this embodiment with corresponding inclined surfaces only against complementary ones Sloping surfaces in the corner area of the cross section of the inner Rod 6.
