发明名称 PORTABLE BARRICADE
摘要 A portable barricade which is particularly adapted for controlling crowds of people. The barricade consists of a length of multiple-ply nylon webbing having hand holds or support loops disposed at spaced intervals along the length and including between the plies a steel cable which extends beyond the ends of the webbing and has fastener loops which are adapted to be connected together. The webbing and the cable therein are sufficiently flexible to permit coiling of the barricade upon itself to form a compact package which may be conveniently carried from place to place.
