摘要

The invention relates to a drive device (1) for a slidable leaf (2) in the form of a sliding leaf or a slidable lift-and-slide leaf of a window or a door (3), comprising a blind frame (4) in which the leaf (2) is held in a slidable manner. In order to slide the leaf (2), the drive device (1) comprises a leaf-side drive motor (5) with a threaded spindle (6) which is driven on the drive motor and is forcibly guided about a gear rack element (7) arranged on the blind frame (4). The gear rack element (7) can be secured in a surrounded manner by the guide rail (10) and is made of tooth segments (47) which can be connected together in a modular manner and form one integral unit.
