Description

Sprossenweise ausfahrbare TeleskopleiterRung-by-rung telescopic ladder

Die Erfindung betrifft eine Leiter, welche teleskopartig, Sprosse für Sprosse auf jede beliebige Höhe ausgefahren werden kann. Dabei muß bei der 3.Sprosse von unten mit dem Auszug begonnen werden.The invention relates to a ladder which can be extended telescopically, rung by rung, to any desired height. The extension must begin at the 3rd rung from the bottom.

Die Stufen sind durch ein Metallverschlußriegelsystem gesichert, das beim Auszug der Leiter in den Holm der nächsthöheren Sprosse automatisch hörbar einrastet.The steps are secured by a metal locking system, which automatically and audibly locks into the rung of the next higher rung when the ladder is extended.

Durch Betätigen des Metallverschlußriegelsystemes an der zweiten unteren Sprosse fährt die Leiter in die Ausgangsposition zurück.By operating the metal locking system on the second lower rung, the ladder returns to its starting position.

Der Vorteil der sprossenweise ausfahrbaren Teleskopleiter zeigt sich an den Stellen, wo herk-ömmliche Leitern nicht eingesetzt werden können, besonders in beengten, niedrigen Räumen und an schwer zugänglichen Orten. Sie ist platzsparend verstau- und leicht transportierbar.The advantage of the rung-by-rung telescopic ladder is evident in places where conventional ladders cannot be used, especially in cramped, low spaces and in places that are difficult to access. It can be stored in a space-saving manner and is easy to transport.

Claims (4)

SchutzansprücheProtection claims 1. Sprossenweise ausfahrbare Teleskopleiter (Fig. la und Ib) dadurch gekennzeichnet, daß die Leiterholme sektionsartig aus einem regelmäßig geschlossenen Profil bestehen, welche an einem Ende aufgeweitet und am anderen Ende verkleinert sind (Fig. 2).1. Telescopic ladder that can be extended rung by rung (Fig. la and 1b), characterized in that the ladder stiles consist of a regularly closed profile in sections, which are widened at one end and reduced in size at the other end (Fig. 2). 2. Sprossenweise ausfahrbare Teleskopleiter nach Anspruch dadurch gekennzeichnet, daß die einzelnen Sektionen der Holme an einem Ende durch die Leitertritte miteinander verbunden sind und sich in den Leitertritten das Metallverschlußriegelsystem (Fig. 3) befindet, außer bei der ersten unteren und der letzten oberen Stufe.2. Telescopic ladder that can be extended rung by rung according to claim 1, characterized in that the individual sections of the spars are connected to one another at one end by the ladder steps and the metal locking system (Fig. 3) is located in the ladder steps, except for the first lower and the last upper step. Sprossenweise ausfahrbare Teleskopleiter nach Anspruch und 2 dadurch gekennzeichnet, daß die Sektionen, bestehend aus zwei Holmen und einem Leitertritt, teleskopartig ineinander passen, und daß beim Aus- und Einfahren der Leiter das Metallverschlußriegelsystem ab der 3.Sprosse von unten automatisch ein- und ausrastet.Telescopic ladder that can be extended rung by rung according to claim 2 and 3, characterized in that the sections, consisting of two stiles and a ladder step, fit into one another in a telescopic manner and that when the ladder is extended and retracted, the metal locking system automatically engages and disengages from the 3rd rung from below. 4. Sprossenweise ausfahrbare Teleskopleiter nach Anspruch 1 bis 3 dadurch gekennzeichnet, daß durch kurzes Ziehen an den Metallringen des Metallverschlußriegelsystemes der zweiten unteren Sprosse (Fig. 4) die Leiter automatisch in die Ausgangsstellung zusammenfährt.4. Telescopic ladder that can be extended rung by rung according to claims 1 to 3, characterized in that by briefly pulling on the metal rings of the metal locking system of the second lower rung (Fig. 4), the ladder automatically retracts into the starting position. Sprossenweise ausfahrbare Teleskopleiter nach Anspruch 1 bis 4 dadurch gekennzeichnet, daß das Metallverschlußriegelsystem in der zweiten unteren Sprosse beim Ausfahren automatisch einrastet, jedoch beim Zusammenfahren der Leiter händisch betätigt werden muß, um wieder auszurasten .Telescopic ladder that can be extended rung by rung according to claims 1 to 4, characterized in that the metal locking latch system in the second lower rung automatically engages when extended, but must be operated manually when the ladder is retracted in order to disengage again.
