PATENTAMT.PATENT OFFICE.
Bei der zusammenlegbaren Baumleiter besteht die Erfindung in der am oberen Ende angebrachten Zangenvorrichtung, durch die bezweckt wird, eine sichere Aufstellung der Leiter zu ermöglichen und ein oberes, seitliches Abrutschen sowie auch ein Ausgleiten am Boden zu vermeiden, wodurch die Leiter besonders bei an Bäumen, Telegraphenstangen usw. vorzunehmenden Arbeiten vorzüglich zu ίο gebrauchen ist.In the case of the collapsible tree ladder, the invention consists in the one at the top attached pliers device, which is intended to ensure a safe installation of the To enable ladder and an upper, lateral slipping as well as sliding out Avoid on the ground, making the ladder especially when on trees, telegraph poles etc. work to be carried out is ideal for ίο.
In der Zeichnung ist
Fig. ι eine Vorderansicht,
Fig. 2 eine Seitenansicht der Leiter,
Fig. 3 eine Einzelheit des Zangengetriebes, Fig. 4 eine Einzelheit der Gelenke im Schnitt
nach der Linie A-B in Fig. 1.In the drawing is
Fig. Ι a front view,
Fig. 2 is a side view of the ladder,
3 shows a detail of the pincer gear, FIG. 4 shows a detail of the joints in section along the line AB in FIG. 1.
Die Leiter kann aus einer beliebigen Anzahl von Teilen bestehen, welche mit einer
Gelenkvorrichtung α (Fig. 2 und 4) versehen sind zum schnellen Auseinanderklappen und
Zusammenlegen. Der feste Stand dieser Verbindung wird durch eine dem Gelenk gegenüberliegende
Vorrichtung mit Haken und Federung b (Fig. i, 2 und 4) erreicht.
Der Hauptteil der Leiter am oberen Ende ist die Zangenvorrichtung, welche den Stamm
von rechts und links faßt und die Standsicherheit der ganzen Leiter bewirkt.The ladder can consist of any number of parts, which are provided with a hinge device α (Fig. 2 and 4) for quick unfolding and folding. The firm state of this connection is achieved by a device opposite the joint with hooks and suspension b (Fig. I, 2 and 4).
The main part of the ladder at the top is the pliers device, which grips the trunk from the right and left and ensures the stability of the entire ladder.
Durch Schlüssel c (Fig. 3, oben) oder durch Kettenantrieb mit Übersetzung und Kurbel d (Fig. ι und 2, unten) an der Leiter werden die geriffelten Zangenbacken β (Fig. 1 bis 3), welche an der Führungsstange f (Fig. 1) laufen, durch Rechts- und Linksgewinde g an den Stamm angepreßt, was den zu Anfang genannten Zweck erfüllt.With key c (Fig. 3, above) or by chain drive with translation and crank d (Fig. Ι and 2, below) on the ladder, the corrugated pliers jaws β (Fig. 1 to 3), which are attached to the guide rod f (Fig . 1) run, pressed against the trunk by right-hand and left-hand threads g , which fulfills the purpose mentioned at the beginning.
Außer Gebrauch kann die Vorrichtung leicht abgenommen werden, weil sie nur durch einen einseitig angenieteten Stift h und eine Schraube mit Kopf und Mutter i an je einen Leiterschenkel befestigt ist.When not in use, the device can easily be removed because it is only attached to a ladder leg by a pin h riveted on one side and a screw with a head and nut i.
