Abstract
A parallel opening hinge (1) comprises a first track (3), a second track (5) and at least two pairs of pivotally connected crossing links (7, 9), wherein each pair of crossing links (7, 9) is mounted to the tracks (3, 5) via a fixed pivot (13, 17) and a movable pivot (15, 19) in each track (3, 5), wherein a connector (23) joins two movable pivots (15) in a track (5) such that the movable pivots (15) move together. Improved opening of a parallel opening vent can thereby result. Other improved features of a parallel opening hinge are also described.
