Abstract (en)
[origin: WO2018114283A1] The invention describes a device for unlocking a landing door, wherein the device comprises: a door leaf (10), which can be moved between an open position and a closed position, a bar (16) arranged on the door leaf (10) to lock the door leaf (10) in its closed position, and an energy accumulator (32) coupled to the door leaf (10), which energy accumulator (32) provides the energy for moving the door leaf (10) into its closed position in the event that the energy supply needed to drive the door leaf (10) fails, wherein the energy accumulator (32) is coupled to the door leaf (10) by means of an elastic element (60) such that through a displacement of the energy accumulator (32) when the door leaf (10) is in its closed position, the bar (16) can be moved to its unlocked position.
