Abstract
Door construction includes a door panel and at the top and at the bottom each time a self-closing pivot hinge. Each of the pivot hinges includes a spring which extends along the rotation axle and which provides a self-closing function to the pivot hinge. Each of the pivot hinges includes a first cam element and a second cam element which are pushed onto each other by the spring and push the door panel towards the closed position under the influence of the spring pressure. The first cam element includes at least one protrusion which upon rotation runs along a running surface with inclined parts of the second cam element. The second cam element is movably mounted in longitudinal direction of the pivot axle by means of a pen which is accommodated in a slotted hole of the second cam element. The slotted hole extends at least partly between the inclined parts of the running surface.
