Description
KAISERLICHES A IMPERIAL A
PATENTAMT.PATENT OFFICE.
Den Gegenstand der Erfindung bildet eine zusammenlegbare Leiter. Von den bekannten
ähnlichen Leitern unterscheidet sich die vor-. liegende im wesentlichen dadurch, daß die
Sprossen abwechslungsweise vorn und hinten an den Leiterholmen befestigt sind, so daß
die Leiter sich enger' zusammenlegen läßt, da die Sprossen sich gegenseitig nicht behindern.
Auf der Zeichnung ist der Erfindungsgegenstand in Fig. ι in einer Ansicht der gebrauchsfertigen
Leiter näher veranschaulicht. Fig. 2 zeigt einen Längsschnitt, Fig. 3 eine Seitenansicht der zusammengelegten Leiter
und Fig. 4 einen wagerechten Schnitt.
An den Seitenteilen α sind Sprossen c mittels Niete b drehbar befestigt. Die
Sprossen c sind ferner, wie die Zeichnung veranschaulicht, oben links und unten rechts
an den Drehpunkten entsprechend abgerundet. Infolge dieser Anordnung können also die
Sprossen sich beim Zusammenlegen der Leiter nicht gegenseitig behindern, es kann
vielmehr die Leiter eng zusammengelegt werden.The subject of the invention is a collapsible ladder. The pre- differs from the known similar ladders. lying essentially in that the rungs are alternately attached to the front and rear of the ladder stiles, so that the ladder can be put closer together, since the rungs do not interfere with each other. In the drawing, the subject of the invention is illustrated in more detail in Fig. Ι in a view of the ready-to-use ladder. FIG. 2 shows a longitudinal section, FIG. 3 shows a side view of the folded ladder and FIG. 4 shows a horizontal section.
Rungs c are rotatably attached to the side parts α by means of rivets b. The rungs c are also, as the drawing illustrates, correspondingly rounded at the top left and bottom right at the pivot points. As a result of this arrangement, the rungs cannot interfere with each other when the ladder is collapsed, rather the ladder can be placed closely together.
Um das selbsttätige Aufklappen der Leiter zu verhindern, ist eine Sicherung d angebracht (Fig. 3).To prevent the ladder from unfolding automatically, a fuse d is attached (Fig. 3).
