Triple-Lock Border Edge and Retain Barrier Apparatus

A landscape border edge and retain barrier apparatus comprising barrier member units manufactured with a unitary body with specific physical characteristics engineered into each barrier member thereby enabling a locking connection between barrier members into an assembly, said physical characteristics are comprising:

• a. a base solid in nature, relatively thin and manufactured from material substantially rigid and suitable to permanent outdoor installation, having an elongate planar surface with opposite first and second base ends and having opposite base sides, the base is sufficiently wide that the member is free standing and thin to be mown over,
• b. a base flange integral with and equal in width to the said base and extending from one or more of said base ends and from either the top or bottom of said base end, said base flange height is such that two base flanges overlapped are equal in height to said base, said base flange length is defined by the distance between the base flange end and the base end,
• c. a wall solid in nature and rigid resisting pressure to flex, said wall extends generally upward vertical from and integral to said base and extends longitudinally between opposite base ends terminating in wall end edges, said wall height is proportionate to base width such that the barrier member is freestanding, said wall width is such that it resists pressure from materials being retained,
• d. a wall flange integral with and equal in height to said wall and extending from one or more of said wall end edges, said wall flange may extend from either side of said wall end edge such that it will overlap an adjacent abutted barrier member wall flange, the width of said wall flange is such that two overlapped wall flanges are equal in width to said wall, said wall flange length is defined by the distance between the wall flange end and the wall end, said wall flange includes a lock pin hole positioned to overlap a similar lock pin hole on overlapped wall flanges,
• e. a base tab extends from said base end and is integral with and on top of said base flange, said base tab is rectangular or square in shape and is somewhat shorter than said base flange, the base tab height is such that the base tab on top of the base flange is equal in height to said base, base tab is intermediate said base flange and said wall flange, base tab is integral with part of said wall flange,
• f. a base slot is included on said base flange extending from the top of the said base end, said base slot extends from base flange end towards base end and is equal in width to base tab on an adjacent abutted member, said base slot is somewhat shorter than said base flange with length being equal to base slot on adjacent member to be abutted and interconnected upon assembly, base slot is underneath a portion of said wall flange such that said wall flange prevents tab and slot separation on vertical axis,
• g. a lock pin hole is included on each wall flange and is positioned to align with additional lock pin holes on overlapped wall flanges of adjacent, abutted members, said lock pin hole is somewhat oblong being wider than the lock pin as to accommodate thermal expansion and contraction,
• h. a lock pin is provided to insert through lock pin holes on assembly of overlapping wall flanges, said lock pin is someone smaller in diameter than the width of the lock pin hole, said lock pin has a lock pin head that is substantially larger that the lock pin hole to provide full coverage of said lock pin hole ensuring full coverage of the vertical surface.
