In a device for closing a wing (4) of a window or door, with a geared motor (3) which moves the wing (4) via a linkage, the geared motor (3) being switchable via a switch, it is proposed, in order to close the wing during the absence of the house owner, that these serve as a linkage a rod movable up against the wing (4) approximately perpendicularly to the wing (4) by means of the geared motor (3), that there be provided in the drive between the geared motor (3) and the rod a slip coupling (8), by which the adjusting force of the rod is limited, and that there serve as a switch for the geared motor (3) a time switch, by which the geared motor (3) can be switched on and where appropriate, switched off, at least the switch-on time of the time switch (21) be adjustable. <IMAGE> |
