Abstract

See full text

A door closing device for a door is described. The device includes an externally powered and/or spring force-powered catch device F for mounting to the stationary door frame TR or the door leaf TF. The catch device has a movably mounted catch element F and an externally powered and/or force storage means-powered drive assembly M connected to the catch element F. It is essential that the catch element F can be connected to and disconnected from the counterpart element, for example the lock latch S, so that the catch element F can be brought into engagement with the counterpart element S for pulling the door leaf TF shut and can be brought out of engagement with the counterpart element S outside of the pulling-shut movement.
