Abstract

A door leaf assembly with door fittings equipped with an add-on module for autonomous power supply, which includes a mechanically operated handle, where the add-on module for autonomous power supply includes at least one part, wherein each of the parts of the add-on module for autonomous power supply is inserted between at least a part of the door fittings and the door leaf. It is advantageous when the add-on module for autonomous power supply contains the central gearbox with the primary gearwheel and at least one secondary gearwheel. The primary gearwheel contains a hole for inserting the axis of the handle. Each secondary gearwheel is connected to one of the main shafts to drive the rotation of this main shaft, each main shaft being connected to either a single electric generator or to a block of at least two electric generators which are kinematically connected to each other.
