Patent ID: 7607645

Claim:
An interlocking barrier system, comprising: a plurality of rigid upright sections which are linkable end-to-end in an interlocking fashion; a connection member embedded in each of a first and a second end of each rigid upright section, each said connection member having a hook member which projects outward from said first or said second end of each rigid upright section wherein said hook member extends linearly a given length along a line running from a top to a bottom of each rigid upright section, wherein said given length along said line running from said top to said bottom of each rigid upright section is greater than 20 inches, a flange member which is recessed in said first or said second end of each upright section wherein said flange member extends linearly said given length along said line running from said top to said bottom of said rigid upright section, and wherein said flange member is positioned behind said hook member in a front to back dimension and includes a portion which projects towards said hook member, and a plurality of bars which extend linearly a given length along a line running from said first end to a second end of each rigid upright section, said given length being equal to or less than a length extending from said first end to said second end at least a pair of deflection limitation stops in the form of plates each having a front side and a back side embedded in each of said first and second ends of each of said rigid upright sections on opposite sides of said connection member at the lower part of each end of each rigid uptight section at a position where the front sides of the plates will face front sides of another pair of deflection stops embedded in an end of an adjacent rigid uptight section of said plurality of rigid upright sections, and where a bar is secured to said back side each of said plates in said pair of deflection limitation stops and extends at an acute angle towards the connection member, whereby said pair of deflection limitation stops provides reinforcement of lower comers of said rigid upright section and prevent spalling.
