• and
• displacing and fixing means arranged to determine a position of said hinge levers relative to one another and formed as a wobble drive, said means having an eccentric associated with said pivot axle and retained in a force-transmitting abutment on said pivot axle, said eccentric being composed of two wedge-shaped cylindrical segments, and a spring element supporting said wedge-shaped cylindrical segments on said pivot axle in a force-transmitting abutment, for spreading apart said wedge-shaped cylindrical segments, said pivot axle being formed by a single one-piece continuous shaft which connects said hinges with one another and has end portions which directly pivotally support one of said hinge levers of each pair of said hinge levers, said shaft having a recess provided in each of said end portions and receiving said wedge-shaped cylindrical segments, and the other of said hinge levers of each pair of said hinge levers surrounding said wedge-shaped cylindrical segments received in said recess.
