Mittelst der beschriebenen Doppelrüstbockleiter soll einem im Bauhandwerk bestehenden Mangel an gutem und einfachem Rüstzeug für äufseren Abputz sowohl wie auch fürs Innere der zu 'verputzenden und decorirenden Räume abgeholfen werden.The middle of the double scaffolding trestle ladder described is intended to be an existing one in the building trade Lack of good and simple tools for external plastering as well as for the interior of those to be plastered and decorated Spaces to be remedied.
Dieselbe ist in beiden auf beiliegender Zeichnung dargestellten Constructionen innen wie aufsen bei Bauten benutzbar und besteht im wesentlichen aus zwei Leitern, deren Schenkel parallel oder divergirend nach unten gehen können, welche entweder allein oder in Verbindung mit je zwei Rüstfüfsen zu den auszuführenden verschiedenartigen Arbeiten zusammengesetzt werden.It is the same inside as in both constructions shown in the accompanying drawing can be used outside in buildings and consists essentially of two ladders, the legs of which can go down parallel or diverging, either alone or in conjunction Assembled with two legs for the various types of work to be carried out will.
Auf beiliegender Zeichnung ist:The attached drawing shows:
Fig. ι eine gewöhnliche Leiter, welche mit einem der in den Seitenansichten der Leiter, Fig. ι a und 1 b, dargestellten Scharniertheile .4r oder B1 versehen ist,Fig. Ι an ordinary ladder, which is provided with one of the hinge parts shown in the side views of the ladder, Fig. Ι a and 1 b, 4 r or B 1 ,
Fig. 2 die Seitenansicht einer einfach zusammengelegten Doppelstehleiter,2 shows the side view of a simply folded double step ladder,
Fig. 2 a Detail des Knotenpunktes der Leiter, Fig. 2 b Schnitt nach a-b der Fig. 2 a,Fig. 2 a detail of the junction of the ladder, Fig. 2 b section after from Fig. 2 a,
Fig. 2 c Schnitt nach c-d, Fig. 2 a.Fig. 2 c section after cd, Fig. 2 a.
Die Zusammensetzung der Leiter zu einer Doppelstehleiter geschieht in der Weise, dafs die beiden an jeder Seite einer jeden Leiter A und B eingelassenen Scharnierbleche A1 und B1 derart zusammengelegt werden, dafs sich der im Scharnierblech B1 befindliche Ausschnitt B2 in den im Scharnierblech A1 an correspondirender Stelle angenieteten Bolzen A2 einlegt. Die Scharnierbleche ^1 und B1 sind an ihrem unteren frei vorstehenden Ende jedes mit einer, wenn zusammengelegt, mit einander correspondirenden Oeffnung.43 Bs versehen. Das Scharnierblech B1 ist des Weiteren mit einer Agraffe oder einem Haken 5* versehen, welcher, wenn nach vorn geklappt, sich um den Bolzen A2 legt und sich mit der an seinem freien Ende befindlichen Oeffnung J35, in welcher eine Lappenschraube C sitzt, genau über die besagten, mit Gewinde versehenen Oeffnungen A3 B3 legt, durch welche dann die Lappenschraube C geschraubt wird. Auf diese Weise sind die beiden Leitern dann in ihrem Knotenpunkt unwandelbar mit einander befestigt.The assembly of the ladder to form a double step ladder is done in such a way that the two hinge plates A 1 and B 1 embedded on each side of each ladder A and B are put together in such a way that the cutout B 2 in the hinge plate B 1 is in the hinge plate A 1 inserts bolt A 2 riveted to the corresponding point. The hinge plates ^ 1 and B 1 are each provided at their lower free protruding end with an opening 4 3 B s that correspond to one another when folded. The hinge plate B 1 is also provided with a clasp or a hook 5 *, which, when folded forward, wraps around the bolt A 2 and the opening J3 5 at its free end, in which a lobed screw C is seated , exactly over the said threaded openings A 3 B 3 , through which the lobe screw C is then screwed. In this way, the two ladders are fixed to one another in their nodal point so that they cannot be changed.
