APPARATUS FOR LIFTING A TWO-LEAF FOLDING TRAP DOOR

摘要

The lifting frame for a two leaf cover with an upper leaf (3) pivoting around a horizontal axis (2) and a lower leaf folding around a parallel axis (4) has a two armed lever (13) pivotally mounted to a side section of the cupboard carcass. The longer arm of the lever is connected to the lower leaf. The lever is longitudinally slidable on its pivot axis and the shorter arm (16) is connected via a slide or roller (17) to a curved guide fixed to the carcass.
