Beschreibung nach Fig. 1 :Description according to Fig. 1 :

Die Erfindung betrifft eine Feststellvorrichtung mit Lenkrolle für Podestleitern oder ähnlich verfahrbaren Arbeitsgeräten, die ein unbeabsichtigtes Verschieben der belasteten Geräte selbsttätig verhindert.The invention relates to a locking device with a swivel castor for platform ladders or similar movable work equipment, which automatically prevents the loaded equipment from being accidentally moved.

Bekannte Einrichtungen gegen unbeabsichtigtes Verschieben sind z.B. federnd gelagerte Rollen, die bei Belastung durch die Standfläche der Leiterfüße ersetzt oder die beim Betreten der Podestleiter selbsttätig festgestellt werden.Known devices to prevent accidental movement include, for example, spring-loaded rollers, which are replaced by the base of the ladder feet when loaded, or which are automatically locked when the platform ladder is stepped on.

Podestleitern mit größeren Podesthöhen und -gewichten haben den Nachteil, daß die Federkraft herkömmlicher federbeiastender Rollen zu schwach ist und schwerer von Hand zu verfahren sind.Platform ladders with larger platform heights and weights have the disadvantage that the spring force of conventional spring-loaded rollers is too weak and they are more difficult to move by hand.

Der Erfindung liegt daher die Aufgabe zugrunde, die vorstehend genannten Nachteile auszuschließen, wie im Folgenden beschrieben.The invention is therefore based on the object of eliminating the above-mentioned disadvantages, as described below.

An einer drehbaren Lenkrolle (1) ist ein U-Profil (2) drehsicher befestigt. Zwischen den zwei gegenüberliegenden Wandungen ist ein Tritthebel (3) mit einer Abdrückrolie (4) verdrehbar befestigt, die sich an einer Abrollfläche zwischen zwei seitlichen Befestigungswinkeln (5) unterhalb der Stufe abrollt, wodurch sich folgender Funktionsablauf, wie in Abb. 1 schematisch dargestellt, ergibt;A U-profile (2) is attached to a rotating castor (1) in a rotationally secure manner. Between the two opposite walls, a step lever (3) is attached to a push-off roller (4) in a rotationally secure manner, which rolls on a rolling surface between two lateral fastening brackets (5) below the step, resulting in the following functional sequence, as shown schematically in Fig. 1;

Befindet sich der Tritthebel (3) unten in Ausgangsstellung, so steht die Podestleiter mit den Leiterfüßen auf dem Boden auf. Um diese verfahren zu können, muß der Tritthebel (3) mit dem Fuß nach oben angehoben werden bis sich die Abdrückrolle (4) über einen oberen Totpunkt an der Abrollfläche feststellt und der Tritthebel (3) gleichzeitig das Trittblech (6) vorne an der untersten Stufe anhebt. Dabei wird die Lenkrolle (1) in Fahrsfeliung nach unten auf den Boden gedrückt und die Leiterfüße stehen nicht mehr auf dem Boden auf, womit die Podesfleiter mit der Lenkrolle und zwei anderen Bockrollen am Stützteil leicht verfahrbar ist.If the step lever (3) is in the starting position at the bottom, the ladder feet rest on the ground. In order to move it, the step lever (3) must be lifted upwards with the foot until the push-off roller (4) is locked above the top dead center on the rolling surface and the step lever (3) simultaneously lifts the step plate (6) at the front of the lowest step. The swivel castor (1) is pressed down onto the ground in the travel position and the ladder feet are no longer on the ground, meaning that the ladder can be easily moved with the swivel castor and two other fixed castors on the support part.

Beim Betreten des Trittbleches (6), das nahezu die Innenbreite der untersten Stufe abdeckt, wird dieses nach unten gegen den Tritthebel (3) gedrückt und löst die Andrückrolle (4) aus der Totpunktstellung, wobei der Tritthebel (3) nach unten in seine Ausgangsstellung zurückfällt und sich die Lenkrolle vom Boden frei abhebt, so daß die Podestleiter wieder mit den Leiterfüßen auf dem Boden aufsteht.When stepping on the step plate (6), which almost covers the inside width of the lowest step, it is pressed downwards against the step lever (3) and releases the pressure roller (4) from the dead center position, whereby the step lever (3) falls back down to its original position and the steering roller lifts freely off the ground so that the platform ladder rests on the ground again with the ladder feet.
