Motor operated separating curtain for halls and theatres - has guide rollers and switch prevent cables from tangling when curtain hits obstacle

摘要

The drive motor (16) operates the drum pulley with cables (24) attached the cables pass over 2 guiding support brackets (17) over the guide roller (14) and then vertically downwards to the sprung winding mechanism of the separating curtain (12). Between the guiding support brackets (17). A weight (18) is attached vertically below the weight is a switch (19) which controls the drive motor (1). If the downward motion of the separating curtain (11) is impeded by an obstruction (22) at floor level (21) the relevant cable will sag and the weight which is attached will depress the switch thereby switching off the drive motor and preventing the cables entangling alternatives to the switch arrangement include infrared sensors and photoelectric cells. USE/ADVANTAGE - Operating mechanism for fire curtains or stage curtains in theatres. Entanglement of the operating cables is prevented.
