Abstract

A separating device for a door leaf that is moveable overhead has a coupling element movable between a coupling position, in which the coupling element couples an output element of the drive device to the structural component, and a freewheeling position, in which the output element of the drive device is decoupled from the structural component. A locking member is provided which is movable between at least one release position, in which the locking member allows a movement of the coupling element into the freewheeling position, and at least one locking position, in which the locking member counteracts a movement of the coupling element into the freewheeling position. The locking member can be coupled to the drive device.
