An assembly comprising:

• a canopy or cover element;
• a body structure including walls defining
• an aperture, and
• hinge means supporting said canopy or cover element for hinging movement between open and closed positions;
• said hinge means comprising a hinge pivot means associated with one of said canopy or cover element and said body structure and rotatably carried by a cooperating element associated with the other of said canopy or cover element or body structure, said hinge pivot means and said cooperating element together defining a hinge axis which is fixed with respect to said canopy or cover element, said hinge pivot means being mounted for limited movement relative to said body structure in a direction transverse to said hinge axis, thereby to allow movement of said hinge axis to accommodate differential expansion of said body structure and said canopy or panel element, wherein said assembly includes support means supporting said hinge pivot means for movement along an arc about an axis spaced from said hinge axis.
