Abstract

A guiding rail for guiding a door leaf between an opening position and a closing position in relation to a door opening in a wall includes: at least one guiding section with a guiding compartment, in which a sliding element is accommodated to be movable, wherein the guiding section includes a guiding opening, through which a bearing axis of the sliding element exits at least partially from the guiding compartment, at which axis a lever element is supportable to be rotationally movable, in order to establish an operative connection between the sliding element and the door leaf. The guiding rail further includes at least one functional section with a functional compartment, in which a transmission means is receivable, which serves for transferring electrical energy and/or data between at least a wall-sided energy source and a door leaf-sided energy recipient and a labyrinth guide between the guiding and functional compartments.
