ABSTRACT:
The invention relates to a lift link gate having a plurality of tabular gate elements 1, 1' which are joined together by joints or hinges 14 about horizontally extending pivot axes (a). The gate slides with the aid of guide pins or rollers 3 in lateral guide tracks 4 which guide the gate from a vertically closed position along an arcuate path into a horizontal open position. To avoid finger injuries in the deflection area of the gate elements, there is provided at the upper edge 5 of each gate element 1 a tooth-like projection 7 substantially symmetrical relative to the gate center plane which has a front flank 10 ascending up to the tooth tip 9 and a rear flank 12 descending from the tooth tip to the rear face 11 of element 1 and at the lower upper edge 6 at least one depression 13 complementary to the projection of the adjacent element 1' is provided, there occuring, upon pivoting of the elements 1, 1' in the arcuate path area of the guide track 4, only an aperture spacing d which precludes the wedging of a finger therein.
