Abstract

Die Erfindung betrifft eine freistehende Leiter, wobei die bisherigen in der Praxis bspw. für die Ernte von Obst, für Baumarbeiten oder andere Tätigkeiten, wie Latemenpflege etc. nur bedingt geeignet sind. Insbesondere beim Obstbau ist eine leichte Handhabung der Leitern, gute Zugänglichkeit von halbhohen Bäumen und Kippsicherheit bei unebenen Gelände erwünscht. Daher ist es Aufgabe der Erfindung, eine standsichere, leicht handhabbare freistehende Leiter zu schaffen. Die Aufgabe wird gelöst durch eine freistehende Leiter mit: zwei an der Leiter befestigten Leiterstabilisatoren 2, 2', mindestens einer zwischen den Leiterstabilisatoren 2,2' befestigten Querstrebe 4; und zwei an den Leiterholmen 1 und am bodenseitigen Abschnitt der Leiterstabilisatoren 2, 2' befestigten Längsstreben 3, 3', wobei die einzelnen Leiterstabilisatoren 2, 2' gemeinsam mit einem Längsstrebenstabilisafionsabschnitt 3a, 3a' und einem Leiterholmabschnitt ein stabiles Dreieck bilden.
