Abstract

Beschrieben wird ein Mast für eine Tragvorrichtung mit Trägern (2), die über einen am Mast geführten Läufer in der Höhe verfahrbar sind und zur Halterung von bühnentechnischen Gerätschaften dienen, wobei der Mast aus mehreren Rohrabschnitten (3a, 3a') gleichen Durchmessers aufgebaut ist, die an den Nahtstellen durch ein Innenrohrstück (9) zueinander ausgerichtet und untereinander verbunden sind,
dadurch gekennzeichnet, dass
das Innenrohrstück aus einer längs einer Mantelline geschlitzten Hülse (9) besteht, die von mindestens einer Druckschraube (17) durchsetzt ist, die über ein Druckstück (24) mit konvexer Außenkontur auf am Rand des Schlitzes (14) vorgesehene Gegendruckstücke (15) mit ebenfalls konvexer Außenkontur einwirkt.
