Separation system has additional blocking element at input end preferably joining blocking elements of double wall in preferably semi-circular shape with external convex side

摘要

The system has at least one passage (8) that can only be practically traversed by persons individually and sequentially and that is bounded on at least one side by a double wall made up of fence-like blocking elements (1-3) terminated at the ends by further blocking elements. The additional blocking element at the input end preferably joins the blocking elements of the double wall in a preferably semi-circular shape with an external convex side.
