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.

Closing device for a door

The invention describes a remote-actuable door opener for installation in a door having a preferably positionally fixed door frame and having a door leaf movably mounted thereon. The door leaf has a movable door opener catch () and a remote-actuable blocking device () which interacts directly or indirectly with the door opener catch () in such a way that the door opener catch () can be switched into a blocking position and into a release position. It is essential that an actuating device () is provided which automatically sets the door opener catch () into a position in which the door opener catch () abuts against the lock catch () in the closed position of the door. Here, the door opener catch () is in particular formed from a bearing body () and from a catch body () which is displaceably guided on the bearing body and which is driven by the actuating device () in the direction of the actuating movement.

Door opening mechanism with automatic adjustment of the door opening latch

The present invention relates to a door opener system having a door opener, which comprises a pivot latch pivotable into the door opener having a stop, having a striker plate, and having a lock latch guide running diagonally inward into the door opener for guiding the lock latch, an adapter part being provided, on which the lock latch guide is implemented and which is situated between the door opener and the striker plate. In order to obtain a flexibly usable and simultaneously reliably functioning door opener system, the lock latch guide is implemented as a slide face, which runs continuously over the stop width and is situated on the door side next to the stop of the pivot latch and adjoining thereto.
