Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die auf beiliegender Zeichnung dargestellte Vorrichtung besteht aus zwei im Winkel gebogenen Armen α α, welche um ihren Scheitelpunkt beweglich sind und deren ein Schenkel zangenförmig ausgebildet ist, während die anderen Schenkel a1 a1 durch entsprechend gebildete Schraubenbolzen in zwei Schlitzen der gleichsam die oberste Sprosse der Leiter bildenden Gleitschiene s geführt werden.The device shown in the accompanying drawing consists of two arms bent at an angle α α, which are movable around their apex and one leg of which is tong-shaped, while the other legs a 1 a 1 by appropriately formed screw bolts in two slots of the top rung as it were s are fed to the conductor forming rail.

Die Scheitelpunkte der Winkelhebel sind mittelst Schraubenbolzen an Kloben befestigt, welche in die Leiterholme am Ende eingeschraubt sind und mit den Winkelhebelh ein Scharnier bilden.The vertices of the angle levers are fastened to clamps by means of screw bolts, which are screwed into the ladder stiles at the end and with the angle lever Form a hinge.

Die Regulirung der nach ihrem Zusammensetzen gleichsam eine Zange bildenden Winkelhebel geschieht mittelst einer gewundenen Zugfeder, welche mit ihren Enden um die Schraubenbolzen zur Führung der Hebel in den Gleitschienen gewunden ist und durch ihre Spannung die Hebelzange in geöffnetem Zustande zu erhalten bestrebt ist, während das überwiegende Gewicht der Leiter und deren Belastung durch den auswärts gerichteten Druck auf die Gleitschiene die Hebelzange schliefst und deren festes Anklammern an die Säule etc. derart bewirkt, dafs ein Gleiten oder Umfallen der Leiter vollständig ausgeschlossen ist.The regulation of the angle levers which, after their assembly, form as it were a pair of pliers happens by means of a coiled tension spring, which with its ends around the screw bolts to guide the lever in the slide rails is twisted and their tension makes the lever pliers open Strives to maintain conditions, while the predominant weight of the ladder and their The lever pliers are loaded by the outward pressure on the slide rail and their firm clinging to the column etc. causes them to slide or Falling over of the ladder is completely excluded.
