The closer (100) has a pinion shaft (104) on which a cam disk (103) is arranged in a rotationally fixed manner and a pressure roller (101). A closing spring (102) forces the pressure roller against a roll-off surface of the cam disk by an operative connection (106, 111, 107). The roller is arranged relative to an axial centre of the pinion shaft in such a way the pressure roller, when a door leaf of a conventional door coupled to the pinion shaft is opened or closed, is moved along a trajectory. The trajectory runs past the axial centre of the pinion shaft and the run-off surface of the disk. |
