Patent ID: 8701248

Claim:
A door construction comprising a door panel and at the top and at the bottom each time a self-closing pivot hinge integrated into the door panel for rotatably suspending the door panel in a door opening, each of the pivot hinges comprising: a first part, provided for being fixed to the door panel, and a second part, provided for being fixed to a side of the door opening, the first and second parts being rotatable with respect to each other about a rotation axle from a closed position in which the door panel closes off the door opening in a first direction towards a first open position and in a second direction, opposite the first direction, towards a second open position; a spring which extends along the rotation axle and which provides a self-closing function to the pivot hinge; a first cam element coupled to the first part and a second cam element coupled to the second part or vice versa, each cam elements having a predefined diameter, the cam elements extending along the rotation axle and being pushed onto each other by the spring upon rotation of the first and second parts with respect to each other, the cam elements being shaped such that they define the open and closed positions of the door panel and that they push the door panel towards the closed position from substantially each intermediate position between the open and closed positions under the influence of the spring pressure; the first cam element comprising protrusions on opposite sides of the rotation axle, which upon rotation run along a running surface with inclined parts of the second cam element; the second cam element being movably mounted in longitudinal direction of the rotation axle by means of a pen which is accommodated in slotted holes on opposite sides of the second cam element; characterised in that each of the slotted holes extends at least partly between the inclined parts of the running surface.
