Abstract
Description
Die Erfindung betrifft eine freistehende Leiter. Bisher ist es in der Praxis üblich freistehende Leitern als Bockleiter, Podestleiter oder als unhandliche Stehleiter mit Stabilisatoren auszuführen. Die in der Praxis für die Ernte von Obst nur bedingt geeignet sind. Schwere Handhabung der Leitern, schlechte Zugänglichkeit von halbhohen Bäumen. Nur bedingte Kippsicherheit bei unebenem Gelände von Bockleitern und Podestleitern.The invention relates to a free-standing ladder. So far it has been common in practice free-standing ladders as step ladders, platform ladders or unwieldy stepladders to be carried out with stabilizers. In practice for fruit harvesting only are conditionally suitable. Heavy handling of the ladders, bad Accessibility from mid-high trees. Only limited safety against tipping uneven terrain of step ladders and platform ladders.
Aufgabe der Erfindung ist es, eine standsichere frei stehende Leiter zu schaffen, die eine gute Zugänglichkeit einzelner Objekte zuläßt, ohne diese zu belasten. Wie zum Beispiel: Obstbäume. Dabei sollte eine gute Handhabbarkeit und ein Anpassen an die örtlichen Gegebenheiten im Vordergrund stehen. Diese Aufgabe wurde wie folgt gelöst.The object of the invention is to provide a stable, free-standing ladder, that allows easy access to individual objects without burdening them. Such as: fruit trees. It should be easy to handle and a Adapt to the local conditions in the foreground. This task was solved as follows.
Eine handelsübliche Leiter wird durch nachstehende Aufbauteile ergänzt oder komplett neu gefertigt.A commercially available ladder is supplemented with the following components or completely new made.
Zwei Leiterstabilisatoren 2 die vorzugsweise V-förmig nach außen stehen werden drehbar an den Holmen der Leiter 1 befestigt oder in einer Sprosse gelagert. Durch die V-Form wird eine gute Stand bzw. Kippsicherheit erreicht. Dies läßt sich nach Bedarf erhöhen, durch einen breiten Leiterfuß 7, mit eventuell unabhängig voneinander einstellbaren Füßen 8, bei unebenem Gelände. Bei unebenem Gelände ist auch ein nicht einstellbarer Einzelfuß 9 oder eine schmale Leiter 1 bei eingeschränkter Kippsicherheit möglich. Dies ergibt eine Dreipunktauflage oder eine annähernde Dreipunktauflage, wobei man sich beim Leiteraufstieg dem Zentrum nähert.Two ladder stabilizers 2, which are preferably V-shaped to the outside, are rotatably attached to the bars of the ladder 1 or are mounted in a rung. The V-shape ensures good stability and tipping safety. This can be increased as required by a wide ladder foot 7 , with feet 8 that can be adjusted independently of one another, on uneven terrain. In the case of uneven terrain, a non-adjustable single foot 9 or a narrow ladder 1 is also possible with limited safety against tipping over. This results in a three-point support or an approximate three-point support, whereby one approaches the center when climbing the ladder.
Die zwei Leiterstabilisatoren 2 sind nach Bedarf für ein leichtes Händling mit Rädern 5 oder Gleitschuhen 6 ausgerüstet.The two ladder stabilizers 2 are equipped with wheels 5 or slide shoes 6 as required for easy handling.
Um ein Auseinanderdrücken der Leiterstabilisatoren 2 zu verhindern ist eine Querstrebe 4 erforderlich. Die für eine gute Zugänglichkeit der Objekte zurückgesetzt ist. Dies ermöglicht ein umfahren (einfahren) der Objekte. Die beiden Leiterstabilisatoren 2 werden durch die in der Länge veränderbaren Längsstreben 3 am Leiterholm fixiert, dadurch entsteht ein stabiles Dreieck. Durch eine unterschiedliche Fixierung der Längsstreben 3 kann die Leiter an eine Querneigung des Geländes angepaßt werden, durch gleichmäßige Verstellung werden Unebenheiten des Geländes ausgeglichen, oder die Steigung der Leiter geändert. Durch überlange Längsstreben 3 hat man Griffe wie bei einer Schubkarre zum anheben und verfahren. Je nach Gelände und Einsatz sind die Füße möglicherweise mit Dornen bestückt.In order to prevent the conductor stabilizers 2 from being pushed apart, a cross strut 4 is required. Which is reset for easy access to the objects. This enables the objects to be driven around. The two ladder stabilizers 2 are fixed to the ladder rail by the longitudinal struts 3 , which can be changed in length, thereby creating a stable triangle. By fixing the longitudinal struts 3 differently, the ladder can be adapted to a cross slope of the terrain, uneven areas of the terrain can be compensated for by uniform adjustment, or the slope of the ladder can be changed. Due to the lengthways struts 3 , you have handles like a wheelbarrow to lift and move. Depending on the terrain and use, the feet may be equipped with thorns.
