ABSTRACT:
A lift link gate having a plurality of tabular gate elements joined together by joints or hinges about a horizontally extending pivot axis. The gate slides in lateral guide tracks which guide the gate from a vertically closed position along an arcuate path into a horizontally open position. To avoid finger injuries in the deflection area of the gate elements, there is provided at the upper edge of each gate element a tooth-like projection substantially symmetrical relative to the gate center plane which has a front flank ascending up to the tooth tip and a rear flank descending from the tooth tip to the rear face of one of the gate elements and at the lower upper edge at least one depression complementary to the projection of a next adjacent element is provided, and upon pivoting of the adjacent elements in the arcuate path area of the guide track, an aperture region is provided with only a small aperture spacing which precludes the wedging of a finger therein.
