KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft fahrbare Leitern, deren Schwenkachse während des Aufrichtens angehoben wird, und bezweckt, die Stützpunkte der Leiter auf dem Wagengestell unveränderlich zu machen. Letzteres wird nach der Erfindung dadurch erreicht, daß der die Schwenkachse der Leiter tragende Bock um eine unverschiebbar auf dem Wagengestell gelagerte Achse drehbar ist und mit einemThe invention relates to mobile ladders, the pivot axis of which during erection is raised, and the aim is to keep the support points of the ladder on the trolley unalterable close. The latter is achieved according to the invention in that the bracket supporting the pivot axis of the ladder an axis mounted immovably on the carriage frame is rotatable and with a
ίο an ihm konzentrisch zu seiner Drehachse befestigten Zahnbogen in ein ebenfalls unverschiebbar auf dem Wagengestell gelagertes Zahnrad eingreift.ίο attached to it concentrically to its axis of rotation Dental arch engages in a gear wheel that is also immovably mounted on the carriage frame.
In der Zeichnung 'ist eine Ausführungsform der Erfindung dargestellt, und zwar in der Seitenansicht bei aufgerichteter Leiter.In the drawing 'is an embodiment of the invention shown, namely in the side view with the ladder erected.
Der Leiterbock ist mit den unteren Enden seines einen Beinpaares a, das durch Streben e mit den unteren Enden des anderen Beinpaares f fest verbunden ist, auf dem Wagengestell b, und zwar zweckmäßig oberhalb der Stützen c, d auf einer Achse t gelenkig befestigt. In den oberen vereinigten Beinpaarenden ist bei g die Schwenkachse h der Leiter i gelagert. Das Beinpaar/ des Leiterbockes a, f trägt einen Zahnbogen k mit Innenverzahnung. In diesen greift ein Stirnrad /, das auf einer auf dem Wagengestell fest gelagerten Welle m sitzt. Auf dieser sitzt außerdem ein Kettenrad n, das durch eine Treibkette 0 von einem Kettenrade ρ auf der Trommelwelle q angetrieben wird. Durch die Drehung der letzteren im einen oder anderen Sinne erfolgt sonach das Aufrichten und Niederlegen des Bockes und damit das Heben und Senken der Schwenkachse h. ,The ladder bracket is with the lower ends of one pair of legs a, which is fixedly connected by struts e to the lower ends of the other pair of legs f , on the carriage frame b, conveniently attached above the supports c, d on an axis t articulated. In the upper combined leg pair ends, the pivot axis h of the ladder i is mounted at g. The pair of legs / the ladder block a, f carries a tooth arch k with internal teeth. In this engages a spur gear /, which sits on a shaft m fixedly mounted on the carriage frame. A sprocket n is also seated on this, which is driven by a drive chain 0 from a sprocket ρ on the drum shaft q. By rotating the latter in one sense or the other, the trestle is raised and lowered, and the pivot axis h is raised and lowered. ,
Das Aufrichten der Leiter erfolgt gleichzeitig mit dem Heben der Schwenkachse in bekannter Weise durch Aufwickeln des Aufrichtegurtes r auf \die Aufrichtetrommel s, die, ebenfalls auf der WeIIe^ sitzt.The ladder is erected simultaneously with the lifting of the pivot axis in a known manner by winding the erecting belt r onto the erecting drum s, which also sits on the shaft.
