A device for unlocking a landing door includes a door leaf that can be moved between an open position and a closed position, a bar arranged on the door leaf to lock the door leaf in the closed position, and an energy accumulator coupled to the door leaf to provide the energy for moving the door leaf into the closed position in the event that the energy supply needed to drive the door leaf fails. The energy accumulator is coupled to the door leaf by an elastic element such that through a displacement of the energy accumulator when the door leaf is in the closed position, the bar is moved to an unlocked position.
