PCT No. PCT/EP96/04038 Sec. 371 Date Mar. 11, 1998 Sec. 102(e) Date Mar. 11, 1998 PCT Filed Sep. 13, 1996 PCT Pub. No. WO97/10405 PCT Pub. Date Mar. 20, 1997A lift gate has elements which extend across the gate in its entire width. The elements are positioned vertically above each other, and are interconnected on their rear sides by hinges countersunk with respect to the rear side. The elements are guided in a pair of substantially vertical tracks along the sides of the gate. The tracks are bent at the upper edge of the gate in an approximately horizontal direction toward the rear side of the gate. The elements have a cross-sectionally tooth-shaped projection along their upper edge, and a corresponding depression along their lower edge. The depression accommodates the projection of an adjoining element. A cutting plane extends perpendicular to the element and through the hinge axis, and cuts a profile section which, in cross-section, approximately forms a triangle having a front flank and a rear flank, and which, when the gate is closed, extends from the lower edge of the overlying element upwards toward the vertex of the triangle. On the rear side of the tooth-shaped projection along the upper edge, the elements have a rearwardly directed projection which extends in the longitudinal direction of the element, and which, in the closed state of the gate, is positioned between the hinge and the lower edge rearwardly of the overlying element and which, when the gate is opened, forms a gap whose width is smaller than a finger thickness.
