A suspension mechanism for a door construction of the kind which includes a door panel that can be swung vertically up and down, wherein the suspension mechanism includes a stationary pivot means (31) located in the region between the upper and lower parts of the door opening, a first brace means (4) extending from the pivot means (31) to the lower part of the door, a spring means (9) which is tensioned when closing the door (1) and which when opening the door exerts a torque-generating force which pivots the first brace means (4) such as to raise the door panel, and further includes a second brace means (5) whose one end (51) is pivotally connected to the first brace means (4) by a second pivot means (6) at a point between the stationary first pivot means (31) and the point of connection of the first brace means (4) to the lower part of the door, wherein the other end (52) of the second brace means (5) is intended to support against the upper part of the door panel (1), characterized in that the second brace means (5) extends in and is axially moveable through a stationary axial guide (7) located above the first pivot means (31). |
