Description

Vorrichtung zum gelenkigen Befestigen von abnehmbaren Stützen an Freistelleitern Bei den bisher üblichen Freistelleitern ist jede Stütze nur mit einem Holm verbunden. Solche Leitern stehen nicht fest und sind auch für unebenes Gelände ungeeignet. Gemäß der Erfindung werden die Stützen in neuartiger Weise ,an der Leiter befestigt; das obere Ende jeder Stütze ist als Welle ,ausgebildet, die von beiden Holmen getragen wird und so gelagert ist, daß jede Stütze sich unabhängig von der anderen windmühlenflügelartig an der Leiber im Kreise herumdrehen läßt. Dabei kann die Anordnung so sein, daß die Welle sich in ihren an beiden Holmen befindlichen Lagen mitdreht oder daß sie stillsteht und die Stütze an ihr drehbar angebracht ist.Device for the articulated fastening of removable supports on free ladders With the free ladders that have been customary up to now, each support is only connected to one stile. Such ladders are not fixed and are also unsuitable for uneven terrain. According to the invention, the supports are attached to the ladder in a novel manner; the upper end of each support is designed as a shaft, which is carried by both spars is and is mounted so that each support is independent of the other like a windmill turns the bodies around in circles. The arrangement can be such that the shaft rotates in its positions located on both spars or that it stands still and the support is rotatably attached to her.

Hierdurch ist es möglich, die Stützen unabhängig voneinander in verschiedensten Neigungswinkeln gegen die Leiter aufzustellen, so daß die Leiter in jedem, auch in stark bergigem Gelände sicher und fest aufgestellt werden kann. Auch kann man die Leiter leicht über die lotrechte Lage hinaus in die Gegenschräglage kippen. Die Stützen schwingen dabei ,an den Holmen vorbei und stützen sich auf der anderen Seite fest. Die Reichweite der Leiter wird so aufs einfachste und schnellste verdoppelt.This makes it possible to use the supports independently of one another in a wide variety of ways Incline angles against the ladder so that the ladder is in each one, too can be set up safely and securely in very mountainous terrain. You can too Tilt the ladder slightly beyond the vertical position into the opposite inclined position. The supports swing past the spars and are supported on the other Side fixed. The range of the ladder is doubled in the simplest and fastest way.

Die Zeichnung zeigt in Abb-. i und 2 ein Ausführungsbeispiel des Erfindungsgegenstandes. An jedem Holma ist eine Lasche b mit zwei übereinanderliegenden Bohrungen c. ,cl .angebracht. Jede Stützed hat am oberen Ende einen Rundstabe, dessen Ende abgebogen ist und durch die oberen Bohrungen c bzw. durch die unteren Bohrungen cl beider Laschen hindurchgesteckt und gegen Zurückfahren gesichert ist. Statt der Laschen können naturgemäß ,auch andere Befestigungsarten gewählt werden, z. B. Haspen.The drawing shows in Fig-. i and 2 an embodiment of the subject matter of the invention. On each spar is a tab b with two holes c one above the other. , cl .appropriate. Each support has a round rod at the upper end, the end of which is bent is and through the upper bores c or through the lower bores cl of both The tabs are pushed through and secured against retraction. Instead of the tabs Naturally, other types of fastening can also be selected, e.g. B. Hasps.

Wesentlich für .alle Ausführungen ist, daß jede Stütze mit beiden Holmen verbunden ist und windmühlenflügelartig leerumgeschwenkt werden kann.It is essential for .all versions that each support with both Holmen is connected and can be swung empty like windmill blades.
