Title: Door opening mechanism with automatic adjustment of the door opening latch

Abstract: 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 (1) and a remote-actuable blocking device (2) which interacts directly or indirectly with the door opener catch (1) in such a way that the door opener catch (1) can be switched into a blocking position and into a release position. It is essential that an actuating device (200) is provided which automatically sets the door opener catch (1) into a position in which the door opener catch (1) abuts against the lock catch (90) in the closed position of the door. Here, the door opener catch (1) is in particular formed from a bearing body (110) and from a catch body (10) which is displaceably guided on the bearing body and which is driven by the actuating device (200) in the direction of the actuating movement.
