1. Device for unlocking a door, comprising:
an operating element which is intended to be accessible to a user for the purpose of opening the door and which is mounted tiltably relative to the door; a bolt movable between a locking position and an opening position of the door; a coupling which can be placed in the door and which is coupled between the bolt and the operating element for causing a movement of the bolt from the locking position to the opening position upon activation of the operating element, wherein the coupling comprises a pair of scissor arms mounted rotatably around a fixed shaft, and a pair of pivot arms, wherein each pivot arm is connected at a first end for pivoting around a respective first shaft to a respective scissor arm and connected at a second end for pivoting around a second shaft to a push part intended to engage against the bolt, which fixed shaft and first and second shafts are parallel and are intended to extend in a plane substantially parallel to the door, this such that a tilting of the operating element brings about a movement of the push part, which movement of the push part brings about a movement of the bolt. |
