Abstract

This construction relates to a simpler possible use of the folding steps for which an application has already been made under Patent No. 3217334.2. This embodiment has the advantage that is can be used suitably and universally as an escape ladder. By unlocking the roll-out step, the ladder is free to open. The ladder rungs fold at the same time into the horizontal position. Closing of the ladder takes place by drawing the closing linkage into the centre. At the same time as the closing linkage is raised, the movable upright can be pushed together effortlessly. Subsequently the roll-out step is folded up, as a result of which the ladder is locked against external actuation.

Description

Bei dieser Weiterentwicklung der schott bekannten Falt-In this further development of the folding

treppe, handelt es sich um eine Leiterkonstruktion, die für alle Flucht und Revisionsmöglichkeiten verwendung finden kann.staircase, it is a ladder construction that is used for all escape and revision options can be used.

Durch Entriegeln der Ausrollstufe 4( Verriegelung nicht dargestellt) und abklappen der selben, kann der Fahrholm 1 sehr leicht ausgezogen werden, wie in Fig.2 dargestellt.Dabei rollt der Fahrholm 1 auf der Konsole 7 mit Laufrad 8 in Offenstellung.By unlocking the roll-out step 4 (locking not shown) and fold down the same, the handlebar 1 can be pulled out very easily, as in Fig. 2. The travel beam 1 rolls on the console 7 with the running wheel 8 in open position.

Die Leitersprossen 2 die an die Fahrholme 1 angelenkt sind, klappen dabei in die waagerechte Stellung. Dadurch ist die Leiter begehbar, wie in Fig. 1 dargestllt.The ladder rungs 2, which are hinged to the driving bars 1, fold in the horizontal position. This means that the ladder can be walked on, as shown in Fig. 1 shown.

Soll die Leiter wieder geschlossen werden, ist das Schließgestänge 6 über den Bremsnocken 10 in Mittelstellung zu schieben, dargestellt in Fig. 1.If the ladder is to be closed again, the locking rod is used 6 to be pushed over the brake cam 10 into the middle position, shown in FIG. 1.

Durch leichtes Anheben des Schließgestänges ó, werden die Sprossen 2 nach oben eingeknickt und der Fahrholm 1 kann nach dem Gebrauch der Leiter wieder eingeschoben werden.By slightly lifting the locking rod ó, the rungs are 2 buckled upwards and the handlebar 1 can be used again after the ladder has been used be inserted.

Um vom Fußboden unabhängig zu sein, wurde die Ausrollstufe 4 klappbar und gleichzeitig als unterste Sprosse konstruiert. Sie übernimmt ebenfalls die einfache Möglichkeit das Leiterpaket sinnvoll zu verriegeln.In order to be independent of the floor, the roll-out step 4 can be folded down and at the same time constructed as the lowest rung. It also takes over the simple one Possibility to lock the ladder package sensibly.

Als Verriegelung können einfache Rasten oder Klinken, aber auch alle bekannten elektrischen oder pneumatischen Sicherungen eingebaut werden.Simple notches or latches, but also all of them, can be used as locking known electrical or pneumatic fuses can be installed.

Die Impulsentriegelung hat den Vorteil, daß die Leiter nicht von unbefugten Personen benutzt werden kann.The pulse unlocking has the advantage that the ladder cannot be accessed by unauthorized persons People can be used.

Im folgenden werden die Konstruktiotlsmerkmale anhand von -Zeichnungen näher beschrieben.In the following the construction features are based on drawings described in more detail.

Fig. 1 Veranschaulicht die ausgefahrene Leiter, bei der das Schließgestänge G in D1ittelstellung gebracht ist. Bereitstellung zum Einschieben der Leiter.Fig. 1 illustrates the extended ladder in which the locking linkage G is in the middle position. Provision for pushing in the ladder.

Fig. 2 Darstellung der Leiter ist der Ausrollstufe 4 als Träger und Verschlußelement.Fig. 2 representation of the ladder is the roll-out stage 4 as a carrier and Closure element.

Fig. 3 Die Leiterkonstruktion wird in geschlossenem Zustand gezeicht, wobei die Anordnving der einzelnen Bauelemente ersichtlich wird.Fig. 3 The ladder construction is shown in the closed state, whereby the arrangement of the individual components becomes apparent.

Diese erfindungsgemäße Leiterkonstruktion wird für die Sicherheit an allen öffentlichen und privaten gebäuden von großem Nutzen sein.This ladder construction according to the invention is used for safety be of great use in all public and private buildings.

Ein großer Vorteil liegt auch darin, daß die Leiter nur von befugten Personen begangen werden kann.Another great advantage is that the ladder can only be used by authorized personnel People can be committed.

Die Entwicklung dieser Leiter erlaubt außerdem allen Archt.The development of this ladder also allows all archt.

und Bauherren eine formschöne Ausführung der notwendigen Sicherheitsleiter zu instalieren.and builders an elegant design of the necessary safety ladder to install.
