An apparatus for actuating wings, for floor door assemblies in lifts or elevator of the type with one or two automatically opened wings, comprises a motorisation (3) that actuates a closed belt or chain (4), whereto are fastened means (5) for connecting to the wings (2), which define, together with the wings (2), connecting rod-crank mechanisms, so that, in the transmission of motion, the wings or part thereof serve as cranks, whilst the connecting means, whereon the motorisation acts, serve as connecting rods. |
