Abstract:
The invention relates to a drive device for driving an element, having the following: a toothed belt drive with a toothed belt, a frame element which forms two opposite connection plates and a connection wall that connects the two connection plates together, at least three elongated force driving elements which are secured to the toothed belt and are aligned parallel to the width (B) of the toothed belt and parallel to one another and which are arranged within the frame element, wherein a central force driving element is rotationally fixed to the two connection plates, and the end sections of each adjacent outer force driving element extend through curved elongated holes of the connection plate, whereby the outer force driving element can be pivoted and the end faces of the outer force driving elements have cylindrical projections, which are designed as axle stubs and each of which has a roller, outside of one of the connection plates, a toothed disc with tooth recesses for catching teeth of the toothed belt and force driving element recesses for catching the force driving elements, a non-linear guide path, at least some sections of which run parallel to the extension of the toothed belt and in which the rollers arranged on the outer force driving elements are guided, and a drive means which is connected to the frame element and is used to connect to the element to be driven.
