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.

Dependent claims

A drive device (18) for driving an element, comprising

a toothed belt drive with a toothed belt (20),
a frame element (72) that forms two opposite connection plates (44) and a connection wall (76), which connects the two connection plates (44) to one another,
at least three elongate force drivers (22) that are fastened on the toothed belt (20) and aligned parallel to a width B of the toothed belt (20) and parallel to one another,
wherein said force drivers are arranged within the frame element (72), wherein a central force driver (22-1) is fastened on the two connection plates (44) in a rotationally fixed manner and end sections of the adjacent outer force drivers (22) respectively extend through curved oblong holes (48) of the connection plate (44) such that the outer force drivers (22-2, 22-3) can be pivoted, and wherein the ends of the outer force drivers (22-2, 22-3) have cylindrical projections, which are in the form of axle stubs and respectively carry a roller (80), outside of one of the connection plates (44),
a toothed disc (26) with tooth recesses (40) for catching teeth of the toothed belt (20) and force driver recesses (42) for catching the force drivers (22),
a nonlinear guideway (60), which at least sectionally extends parallel to the extent of the toothed belt (20) and in which the rollers (80) arranged on the outer force drivers (22-2, 22-3) are guided, and
a drive means (90) that is connected to the frame (72) element and serves for the connection to the element to be driven.
