Crowd control barrier

Claim 1

A crowd control barrier comprising: a plurality of transportable hollow enclosed containers made from a lightweight, resiliently deformable material, said containers each having a top, a bottom, ends, a first side extending vertically upward from said bottom to said top, a second side extending vertically upward from said bottom a lesser distance than said first side and a third side extending from the uppermost part of said second side in an inwardly sloping direction to said top, said containers each having filler openings situated in said top with one of said filler openings adjacent one of said ends; means for coupling adjacent ends of said containers to one another, said coupling means including a pair of slots formed in each adjacent end at a juncture of the adjacent end and the bottom and extending through said bottom and a predetermined distance toward an opposite end and parallel with said first and second sides, each of said slots dimensioned to receive in snug fit a portion of a stud such that when said containers are positioned adjacent one another the slots in each are in alignment and said stud is positioned in the slots formed in each of said containers, wherein introducing a liquid into said containers through said filler openings causes said resiliently deformable material to deform, clamping said stud and locking said containers in position; and a drain formed in said second side of the containers and adjacent the bottom whereby said liquid may be drained from said containers, unclamping said stud and permitting the containers to be separated.
