und Verminderung des Gewichtes zwischen den beiden Holmteilen eine dünne Metallschiene anzuordnen.
Demgegenüber sollen aber bei der erfindung- gemässen Leiter die Holme deshalb aus zwei fest miteinander verbundenen Holzbalken be- stehen, um etwaige Fehlerstellen in den beiden
Holzbalken gegeneinander zu versetzen.
Durch die besondere Lage der Struktur- zeichnungen der beiden Holzlatten zueinander soll ferner ein etwaiges Verziehen der Holme vermieden und eine grössere Tragfähigkeit der
Holme erreicht werden.
In der Zeichnung ist die Leiter beispielsweise dargestellt. Als Leiterholme dienen je zwei an ihren Breitseiten 1 miteinander verbundene, z. B. verleimte Latten 2 und 3. Die Holme liegen mit ihren Breitseiten quer zu den Leitersprossen 4.
Die Strukturzeichnungen je zweier Lattenquerschnitte sind in bezug auf die Stosskante annährend symmetrisch. Der besseren Verdeutlichung wegen ist im Holm 2 bei 5 und im Holm 3 bei 6 je eine Fehlerstelle eingezeichnet, um zu zeigen, wie durch die erfindungsgemässe Anordnung derartige Stellen gegeneinander versetzt werden können, so dass nirgends der ganze Querschnitt eines Holmes fehlerhaft ist.

and to reduce the weight between the two spar parts to arrange a thin metal rail.
In contrast, however, in the ladder according to the invention, the stiles should therefore consist of two wooden beams that are firmly connected to one another to avoid any faults in the two
To offset wooden beams against each other.
Due to the special position of the structural drawings of the two wooden slats to one another, any warping of the spars should also be avoided and the load-bearing capacity of the
Holme can be reached.
In the drawing, the ladder is shown for example. As ladder stiles each serve two interconnected at their broad sides 1, z. B. glued battens 2 and 3. The broadsides of the stiles lie at right angles to the ladder rungs 4.
The structural drawings of two slat cross-sections are approximately symmetrical in relation to the abutting edge. For the sake of clarity, a fault point is shown in the spar 2 at 5 and in the spar 3 at 6 to show how the arrangement according to the invention can offset such points from one another so that the entire cross-section of a spar is nowhere faulty.
