摘要

The device (5) has a connecting rod fitting (3) for selective locking of a leaf opposite a frame (1) or releasing the leaf movement in rotational or tilting positions. A hand-operated drive unit is arranged at the leaf for moving a rod. A coupling unit establishes a positive locking between a motor-driven drive unit and the rod. A centering unit (11) aligning the leaf has base parts fastened to the frame and an upper part covering the base parts. The upper part has a recess for a centering component fastened to the leaf, and is positively fixed to the base parts in different positions.
