BeschreibungDescription
LeiterDirector
Die Erfindung betrifft eine Leiter mit zwischen Leiterholmen angeordneten Trittstufen oder Sprossen.The invention relates to a ladder with steps or rungs arranged between ladder stiles.
Als Steighilfen sind unterschiedliche Leitertypen bekannt, beispielsweise Anstellleitern und Stehleitern. Die Verwendung der Leitern in schrägem oder unebenem Gelände oder an Treppen oder Podesten ist oftmals sehr problematisch, da die bekannten Leitern keine Einrichtungen haben, sie an unebenes Gelände anzupassen. Dies kann ein hohes Unfallrisiko für den Benutzer bedeuten.Different types of ladders are known as climbing aids, for example leaning ladders and step ladders. Using the ladders on sloping or uneven terrain or on stairs or platforms is often very problematic, as the known ladders do not have any devices to adjust them to uneven terrain. This can mean a high risk of accidents for the user.
Der Erfindung liegt die Aufgabe zugrunde, eine Leiter zu schaffen, die Einrichtungen besitzt, mit denen die Leiter an schräges oder unebenes Gelände angepasst werden kann.The invention is based on the object of creating a ladder which has devices with which the ladder can be adapted to sloping or uneven terrain.
Die Lösung dieser Aufgabe erhält man durch die im Anspruch 1 angegebenen Merkmale. Die erfindungsgemäße Leiter besitzt teleskopartige oder klappbare Stützen, die mittels Arretirelementen auf unterschiedliche Stützlängen einstellbar sind. ( FIG 1,2,3 ).This object is achieved by the features specified in claim 1. The ladder according to the invention has telescopic or foldable supports which can be adjusted to different support lengths by means of locking elements. ( FIGS. 1, 2, 3 ).
Bei längeren Teleskopstützen kann es vorteilhaft sein, wenn diese gegen seitliches Ausbrechen miteinander verstrebt werden. Die Querstreben sollen dann vorzugsweise am unteren Ende der jeweiligen Teleskopstütze angebracht werden.For longer telescopic supports, it can be advantageous to brace them against sideways breaking. The cross braces should then preferably be attached to the lower end of the respective telescopic support.
Anstelle von verstellbaren Stützen kann auch dadurch an das Gelände angepasst werden, indem man den Winkel (0?) zwischen Leiter und Stützen verstellen kann ( FIG. 5 ,6 ). Ein entsprechendes Arretierelement muß an den DrehpunktenInstead of adjustable supports, the ladder can also be adapted to the terrain by adjusting the angle (0?) between the ladder and the supports ( FIG. 5 , 6 ). A corresponding locking element must be attached to the pivot points
von Leiter und Stützen angebracht sein. 10of ladder and supports. 10
Handelt es sich um eine Anstellleiter, genügt eine Teleskopverlängerung an einem Leiterholmen ( FIG. 7,8,9,10,11 ).If it is a step ladder, a telescopic extension on one of the ladder stiles is sufficient ( FIG. 7,8,9,10,11 ).
Zur Erhöhung der Standfestigkeit dienen unten Querholme. In diesem Fall muß bei einem der Leiterholme der Drehpunkt für den Querholm in einem Langloch geführt werden, damit der Drehpunkt hin- und hergleiten kann. ( FIG. 7,8,9 )Crossbars are used at the bottom to increase stability. In this case, the pivot point for the crossbar must be guided in a slotted hole on one of the ladder bars so that the pivot point can slide back and forth. ( FIG. 7,8,9 )
Schließlich läßt sich die Neigung der Aufstellfläche auch ^O dadurch erreichen, indem die Leiterholmen unten zusammenführt werden und an einem zentralen Punkt ein drehbarer Querholm angebracht wird, der über eine kreisförmige Arretierscheibe oder Arretierring in seinem Winkel eingestellt werden kann. ( FIG. 12,13 )
25Finally, the inclination of the installation surface can also be achieved by bringing the ladder stiles together at the bottom and attaching a rotating cross stile to a central point, the angle of which can be adjusted using a circular locking disc or locking ring. ( FIG. 12,13 )

Gebräuchlich sind auch Leitern, bei denen frei schwenkbare Stützen eine Anpassung an unebenes bzw. abschüssiges Gelände ermöglichen. Die dabei gesetzten Grenzen können erweitert werden, indem man die Stützen als Teleskopstützen auslegt. ( FIG. 4 )Ladders with freely pivoting supports that allow adaptation to uneven or sloping terrain are also common. The limits set here can be extended by designing the supports as telescopic supports. ( FIG. 4 )
Als Arretierelemente sind verschiedene Lösungen möglich: mittels Klappklemmen, wie man es von Fotostativen kennt, mittels Klemmschrauben,
mittels Lochreihen und Sicherungsstiften, mittels Zahnstangen und entsprechenden Arretierelementen.Various locking solutions are possible: using folding clamps, as is known from photo tripods, using clamping screws,
by means of rows of holes and locking pins, by means of racks and corresponding locking elements.
Die Erfindung wird nachfolgend anhand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert.The invention is explained in more detail below with reference to embodiments shown in the drawings.
