Abstract

The present invention relates to a closing force assistance device (2) for a fire-door closer.  Axially connected with the rotational shaft (40) of a door closer (4) there is a rotational body (28) which is formed with a pinion gear unit (28a) on one part of the cylindrical outer circumferential surface and which is equipped with an actuator (26) having a rack gear unit (26a) and a bias spring (24) on a linear working chamber (36)in an upper and a lower case (20)(22). Before the fire door (8) is completely closed, engagement takes place between the pinion gear unit (28a) and the rack gear unit (26a) in a fire-door closing-force augmentation zone.
