Description
Um einen am Baumstamm befestigten Mast schwenkbare Baumleiter. Die Erfindung betrifft eine Baumleiter, die um einen am Baumstamm befestigten Mast verschwenkbar ist. Das Neue besteht darin, daß die oberen Enden der Leiterwangen zu einer Schleife ausgebildet sind, welche den über die Baumkrone hinausragenden Teil des am Baumstamm befestigten Mastes umfaßt. Dadurch erzielt man für die Leiter einen festen Stand, und sie kann auch leichter gebaut sein, als wenn sie nur vom Schwenkarm gehalten wird.Tree ladder swiveling around a mast attached to the tree trunk. the The invention relates to a tree ladder which can be pivoted about a mast attached to the tree trunk is. The new thing is that the upper ends of the ladder cheeks form a loop are formed, which protrudes over the treetop part of the tree trunk fixed mast included. This gives the ladder a firm footing, and it can also be built lighter than if it were only held by the swivel arm will.
Auf der Zeichnung ist eine beispielsweise Ausführung der Erfindung in Abb. z in schaubildlicher Ansicht dargestellt.The drawing shows an example embodiment of the invention shown in Fig. z in a diagrammatic view.
Die Abb. 2 und 3 zeigen Einzelheiten. Ein Mast a, der aus Einzelteilen zusammengesetzt werden kann (Abb. a), ist mittels Riemen b o. dgl. am Stamm befestigt. Die Leiter besteht aus zwei Wangen e und einer Versteifungsstrebe f nebst den Stufen g. Die oberen Enden der 'Wangen sind zu einer bei aufgestellter Leiter etwa wagerecht liegenden Strecke h umgebogen; dadurch kommt die Leiter an der Außenzone des Baumes zu stehen. Die eine Wange endet in einer Schlaufe i, an der die andere Wange angeschweißt ist.Figures 2 and 3 show details. A mast a, which can be assembled from individual parts (Fig. a), is secured by means of belt b or the like attached to the trunk. The ladder consists of two cheeks e and a stiffening strut f together with levels g. The upper ends of the 'cheeks are at one with erect Ladder bent over approximately horizontal route h; this is how the ladder arrives to stand in the outer zone of the tree. One cheek ends in a loop i, an the other cheek is welded on.
Die Leiter wird mit der Schlaufe i über den Mast a gehoben. Unten steht sie auf, oben stützt sie sich mit der Schlaufe am Mast ab. Dadurch entsteht ein Versteifungswinkel, der sicheren Halt gibt. Je steiler die Leiter steht, desto höher geht sie hinauf; je flacher sie gestellt wird, desto tiefer rückt das Oberende am Maste herunter.The ladder is lifted with the loop i over the mast a. Below she stands up, at the top she supports herself with the loop on the mast. This creates a stiffening bracket that provides a secure hold. The steeper the ladder, the higher it is higher it goes up; the flatter it is made, the lower the top moves down the mast.
Zur Sicherheit kann man an der Schlaufe noch eine Klemmvorrichtung anbringen, die während des Anlegens oder Verstellens durch einen vom Boden aus zu handhabenden Zug geöffnet werden kann und nach Freigabe selbsttätig in Wirkung tritt.To be on the safe side, a clamping device can be attached to the loop attach the during the creation or adjustment by one from the ground handling train can be opened and automatically takes effect after release.
