ABSTRACT:
A knuckle joint hinge having a supporting-wall and a door part which are joined together by a knuckle joint mechanism formed by two link arms coupled pivoting together in their middle area, one end of the one link arm being articulated to the supporting-wall part and one end of the other link arm to the door part, the other end in each case being guided along a curve in space and coupled to the respective other part. In the portion of the knuckle joint mechanism that is formed by the door-side lever arms of the link arms, a filler piece is mounted so as to be variable in position. This filler piece is biased into a position covering the variable gaps which form between the door-side lever arms and between the lever arms and the door during the opening and closing movement, and it supports itself against the door or the door part, as the case may be, by means of a cam on its side facing the door.
