A lever mechanism (1) for controlling a roof hatch comprising a guide shaft (2) and two levers (3, 4), both of which are in the mounted state connected at one end (6, 7) to the roof hatch and at the other end movably connected to the guide shaft, and further comprising distance means (9, 11) which are coupled to the coupling points (10, 12) of the levers, which coupling points (10, 12) are located between the extremities of the levers for the maintenance of a permanent distance of the coupling points (10, 12) of the levers with respect to the support positions near the guide shaft (2). The distance means (9, 11) are executed as guide slots, and between its extremities each lever is provided with a coupling element (10, 12) for engaging a guide slot, such that when a lever is moved along the guide shaft (2), that end of the lever (6, 7) which is coupled to the roof hatch will run along a trajectory of movement determined by the guide slot. |
