The invention relates to a drive system for actuating hinged building closures, comprising at least two displaceably mounted control organs for displacing the building closures. Said system is characterised in that each control organ is connected to a respective guide element (7). Each guide element (7) is displaceably mounted in a profiled section (4) and fixed to a chain (3) of a chain drive that runs continuously in the profiled section (4). The chain drive has a central drive mechanism (2) for the chains (3) in the profiled sections (4). |
