Abstract (en)

Drivers (285,286) fitted both sides of the lever (28) in its swivel plane contact a stop plate (291) to reach the working settings so as to adjust the plate and in this way shift a cam (343,344) out of normal into working position in which the rope (17,18) is pressed against the pulley (22,23). The drivers come in pin form and the stop plates (291) are fixed to a slide (29) which is fitted at its ends with latching plates (33) and so acts on the cams. The cam is mounted on a shaft taking a pin (341) which normally enters the latching plate itself adjusting parallel to the pin. Preferably a pair of pulleys are provided and are exposed to a pair of cams mounted on the shaft.

Abstract (de)

Die Erfindung beinhaltet eine mechanische Anordnung zur Begrenzung der Bewegung, insbesondere der Neigung von Arbeitsbühnen (10), bei der ein Hebel (28) durch mindestens ein über eine Rolle (22,23) geführtes Seil (17,18) aus seiner Normalstellung in ein Arbeitsstellung ausgelenkt wird und dabei die Klemmung des Seiles (17,18) bewirkt. Um diese Anordnung bei Verwendung von C-Bügeln (11,12) unabhängig von der Neigungsrichtung wirksam zu gestalten sind am Hebel (28) zu beiden Seiten seiner Mittellinie in seiner Schwenkebene Mitnehmer (285,286) befestigt, von denen jeweils einer zum Erreichen der Arbeitsstellung eine Platte (291) kontaktiert und verstellt, die bei ihrer Verstellung die Bewegung mindestens eines Exzenters (343,344) aus seiner Normalstellung in seine Arbeitsstellung freigibt, in welcher er das Seil (17,18) gegen die Rolle (22,23) preßt und damit eine weitere Neigung der Arbeitsbühne (10) verhindert. <IMAGE>
