Abstract
A rod system device extending from its lock unit to a tensioning devicc of the door catch mechanism which takes up two positions is connected in the door catch mechanism with a pivotable unlocking hammer so that the door catch mechanism can be released from the drive rod locking mechanism. The door catch mechanism has an unlocking lever which, when engaged with a bolt element, is ready for contact opposite a trigger element of the tensioning device so that following the unlocking of a bar/drive rod locking unit with the lock unit, the bolt element can be moved from the engagement position to a release position by deflection of the unlocking hammer.
Claims9
A locking device for a door with a rigid frame, the locking device including:
- a drive rod locking mechanism disposed in a door wing, the drive rod locking mechanism having a bar/drive rod locking unit which can be locked by means of a lock unit;
- a door catch mechanism disposed separately from the drive rod locking mechanism, wherein, with a tensioning device which can take up two end positions, a bolt element disposed opposite an energy storage device can be pushed into an engagement and a release position in a catch unit hinged on a rigid door frame, and
- a rod system device extending from the lock unit to the tensioning device and connected with an unlocking hammer pivotably movably arranged in the door catch mechanism, the door catch mechanism having an unlocking lever which, in the engagement position of the bolt element, is positioned ready for contact opposite a trigger element of the tensioning device,
- so that, following unlocking of the bar/drive rod locking unit with the lock unit the bolt element can be moved from the engagement to the release position by a deflection of the unlocking hammer.
