Hinge comprising a non-parallelogram quadrilateral pivoted linkage comprising: a first member (11) arranged to be rigidly secured to a fixed window frame; a second (stile) member (12) arranged to be rigidly secured to an opening edge (as defined) of a movable wing of the window; a short third link member (13) pivotally connected between the first and second members and movable between a closed position substantially aligned with both said first and second members and an open position substantially aligned with the second member only; and a longer fourth link member (14) pivotally connected between the first and second members and movable between a closed position substantially aligned with both said first and second members and an open position angled with respect to the other three members of the linkage; both the third and fourth link members (13, 14) opening in the same direction of rotation between the closed and open positions. |
