 chung reagieren, an hohen Leitern anbringen zu können. 



   Die Erfindung ist in der Zeichnung in einer   beispielsweisen Ausführungsform   dargestellt. Es zeigen Fig.   l   schaubildlich die Verbindung zwischen Holmen, Treten und Sprossen, Fig. 2 eine Vorderansicht, Fig. 3 eine Seitenansicht der Leiter ohne die Treten, Fig. 4 eine Vorder-und Fig. 5 eine Seitenansicht der fertigen Leiter. 



   Die beiden Holme 1 sind zur Befestigung der Treten 5 in üblicher Weise mit den Nuten 2 versehen und haben unterhalb dieser Nuten Zapfenlöcher 3 in solchem Abstande von den Nuten, dass die in die Löcher 3 eingefügten Sprossen 6 im Abstande von den Treten zu liegen kommen. Die Sprossen werden mit hochkant gestelltem Zapfen in die Holme eingekeilt. Sodann werden die Treten   5   eingeschoben und mittels Schrauben od. dgl. gegen Herausfallen aus den Nuten 2 gesichert. 



   Es hat sich gezeigt, dass diese Bauart die Herstellung hoher Leitern ermöglicht, die auch bei langandauernde Benutzung nicht locker werden und eine sichere und gefahrlose Benutzung gewährleisten.

 EMI1.1
 to be able to attach to high ladders.



   The invention is shown in the drawing in an exemplary embodiment. 1 shows the connection between stiles, steps and rungs, FIG. 2 a front view, FIG. 3 a side view of the ladder without the steps, FIG. 4 a front and FIG. 5 a side view of the finished ladder.



   The two bars 1 are provided with the grooves 2 in the usual way for fastening the steps 5 and have peg holes 3 below these grooves at such a distance from the grooves that the rungs 6 inserted into the holes 3 come to lie at a distance from the steps. The rungs are wedged into the stiles with the tenons upright. The steps 5 are then pushed in and secured against falling out of the grooves 2 by means of screws or the like.



   It has been shown that this type of construction enables the production of tall ladders which do not become loose even with long-term use and ensure safe and risk-free use.
