Abstract

Przedmiotem rozwiązania jest mechanizm dźwigający dla nożycowych schodów strychowych, schody strychowe i sposób dźwigania drabiny nożycowej schodów strychowych za pomocą mechanizmu dźwigającego, przy czym mechanizm dźwigający z napędem elektrycznym zbudowany jest z ramy nośnej (5), półramy na której zawieszony jest napęd elektryczny (72) oraz półrama zbudowana jest z ramiaka poprzecznego i dwóch ramiaków bocznych tak, że ramiaki boczne półramy zamocowane są przegubowo do ramy nośnej (5), przy czym każdy z ramiaków bocznych posiada układ podciągający, do podciągania nożycowej drabiny (3) schodów strychowych, przy czym układ podciągający zajmuje pozycje zwolnioną i pozycję aktywną podczas pracy mechanizmu dźwigającego.
