Abstract
Vorrichtung zum Geländeausgleich für Leitern und Gerüstständer, die nur ein minimales Eingreifen des Benutzers erfordert. Es genügt ein langsames Absetzen der senkrecht gehaltenen Leiter.
Wesentlicher Bestandteil der Vorrichtung ist eine zwischen den Halmen (1,2) unter der untersten Sprosse seitlich verschiebbar angebrachte Traverse (3), an der zwei Standbeine (6,7), schwenkbar befestigt sind. Jedes dieser Standbeine ist in die Richtung eines Halms geschwenkt und wird dort mit einer Beinführung (8,9) unter dem jeweiligen Holm durchgeführt oder an ihm vorbei geführt. Die Beinführungen halten die Standbeine so, dass noch eine Schwenkbewegung und eine Bewegung entlang ihrer Längsachse möglich ist.
Durch Verschieben der Traverse wird die Steilheit der Standbeine unterschiedlich verändert. Dies bewirkt den Ausgleichseffekt. Die Anordnung kann so gestaltet werden, dass sich die Traverse selbstständig verschiebt, solange beim Absetzen nur ein Standbein den Boden berührt. Sobald beide Standbeine den Boden berühren und die Leiter belastet wird, ist ein sicherer Stand gewährleistet.
Device for terrain compensation for ladders and scaffold stands, which requires only minimal intervention of the user. It is sufficient to slowly settle the vertically held ladder.
An essential part of the device is a between the stalks (1,2) under the lowest rung laterally slidably mounted cross member (3), are pivotally mounted on the two legs (6,7). Each of these legs is pivoted in the direction of a straw and is carried out there with a leg guide (8,9) under the respective spar or past him. The leg guides hold the legs so that a pivotal movement and a movement along its longitudinal axis is still possible.
By moving the traverse the steepness of the legs is changed differently. This causes the balancing effect. The arrangement can be designed so that the truss moves independently, as long as only one leg touches the ground when weaning. Once both legs touch the ground and the ladder is loaded, a secure stand is guaranteed.
