Abstract (en)
[origin: EP1028223A2] The auxiliary drive for a door into a building, and especially a powered roller or up-and-over door, has a rotary drive unit (12) in a bearing mounting (18) with at least one movement component parallel to the rotation of the chain drive (40) which operates the door. In the rest position, the two rotating units (12,40) are disengaged from each other, and are engaged together when there is a relative and parallel movement between them, with meshing tooth sectors (62,64) forming a reduction gearing to rotate the chain drive and move the door.
