Abstract: A gate includes a gate leaf which is movable between a closed and an open position, and a plurality of gate leaf elements, which are tiltable. The gate leaf includes a door leaf which is swingable around a pivot axis extending perpendicular to the tilt axes. When closed, the door leaf is mounted in an opening in the gate leaf and the door leaf extends essentially parallel to the plane of the gate leaf. A stabilizing arrangement opposes the deformation of the gate leaf and a threshold element which rests on the floor of the opening when the gate leaf is in the closed position. The height of the threshold element is essentially less than 20 mm, preferably less than 10 mm.

Abstract: An openable barrier system for use with a horizontal surface. The system includes first and second support structures fixedly mounted to the horizontal surface an a barrier mounted to the first support structure and pivotable between a first position in which a latching mechanism incorporated with the second support structure securedly engages the barrier and a second position in which the barrier permits travel between the support structures. The latched engagement of the latch means and the barrier may be released from a first remote location. When the barrier is unlatched, spring energy sufficient to pivot the unlatched barrier into the second position is released. As the unlatched barrier pivots into the second position, a depressible pedal mechanically associated with the rotating member is raised. By later depressing the raised pedal, the rotating member may be rotated against the spring force to pivot the barrier into the first position. The latching mechanism then engages the barrier.
