DOOR DRIVE ARRANGEMENT WITH A BLOCKING DEVICE AND DOOR PROVIDED THEREWITH

摘要

The invention relates to a door drive arrangement (18) for moving a door leaf (16) of a door. The door drive arrangement (18) comprises a motor (22), a driver (26) and a slide-open safeguard (34). The door leaf (16) can be connected to the driver (26). The driver (26) can be moved by the motor (22) into an opening position for completely opening the door leaf (16), into a closing position for completely closing the door leaf (16) and into a partial opening position for partially opening the door leaf (16) for the purpose of ventilation. The slide-open safeguard (34) is provided with a blocking member for blocking the driver (26) in the case of a force exerted on the driver (26) by the door leaf (16) by positively gripping a counter-bearing member. The slide-open safeguard has a partial opening position counter-bearing member (36) in order to block the driver (26) in the partial opening position. It is thus possible to effectively prevent the door leaf (16) from sliding open even in a partial opening position.
