Abstract

Przedmiotem zgłoszenia jest rolowana kurtyna dymowa, stanowiąca jedno z zabezpieczeń przeciwpożarowych, które ma szczególne zastosowanie w budynkach wielokondygnacyjnych, zwłaszcza w budynkach z dziedzińcem wewnętrznym. Rolowana kurtyna dymowa ma elastyczny płaszcz (1), przytwierdzony górnym obrzeżem do poziomego wału nawojowego (2), który jest zamocowany swymi końcami do obrotowych opraw (3) ułożyskowanych w stałych podporach (4). Kurtyna charakteryzuje się tym, że co najmniej jedna z obrotowych opraw (3) wału (2) jest wyposażona w mechaniczne urządzenie blokady jego ruchu obrotowego, które jest przyłączone do wyzwalacza blokady, osadzonego na podporze (4) oprawy (3). Urządzenie to stanowi zapadkowy mechanizm, składający się z zębatego koła złączonego z oprawą (3) wału (2) i wahliwej, zapadkowej dźwigni z zapadkowym występem.  Występ jest zazębiany z zębatym kołem oprawy (3) pod naciskiem sprężyny. Jeden z końców zapadkowej dźwigni jest przyłączony obrotowo do stałej podpory (4), a ponadto zapadkowa dźwignia ma połączenie z wahliwym ramieniem wyzwalacza blokady za pośrednictwem poprzecznego łącznika.The subject of the notification is a rolled smoke curtain, which is one of the fire protection measures, which is especially used in multi-storey buildings, especially in buildings with an internal courtyard. The rolled smoke curtain has a flexible jacket (1), attached with its upper rim to the horizontal winding shaft (2), which is fixed with its ends to the rotating housings (3) mounted in fixed supports (4). The curtain is characterized in that at least one of the rotating mounts (3) of the shaft (2) is equipped with a mechanical device for blocking its rotation, which is connected to a lock actuator mounted on the support (4) of the mount (3). The device is a ratchet mechanism consisting of a toothed wheel connected to the housing (3) of the shaft (2) and a rocking, ratchet lever with a ratchet projection. The protrusion is meshed with the gear wheel (3) under spring pressure. One end of the ratchet lever is pivotally connected to the fixed support (4), and further the ratchet lever is connected to the swing arm of the lock actuator via a transverse link.
