Abstract

A device for at least partially automatically actuating a door leaf, includes a drive having a drive axis of rotation for driving the door leaf at least partially during a movement between an opening position and a closing position, a casing element having a casing axis of rotation for assisting a movement of the door leaf, lever kinematics having at least one lever arm for establishing an operative connection between the drive and the casing element. The lever arm includes a drive-sided connection section, which is supported to be rotationally movable around the drive axis of rotation. The lever kinematics includes at least one transmission component for transferring electric energy and/or data between at least one casing-sided energy source and a drive-sided energy recipient. The connection section has a cranked course, wherein a multi-layered functional compartment for mechanically connecting the lever arm and for electrically connecting the transmission component to the drive is configured along the cranked course of the connection section.
