Patent ID: 8297873

Claim:
A bollard assembly, comprising: a post comprising a generally cylindrical post wall forming a cavity, the post wall having a passage extending generally longitudinally along the post wall, and a stop plate secured to one end of the post wall and extending across the cavity; an insert positioned within the cavity of the post, the insert comprising a pipe, a generally penannular wedge extending radially outward from the pipe and defining a gap therein; and a sleeve comprising a generally cylindrical sleeve wall forming a cavity and a latch pin attached to the sleeve wall and extending into the cavity of the sleeve; wherein the sleeve is adapted to receive the post such that the latch pin travels through the passage in the post wall and the gap in the wedge of the insert when the passage in the post wall and the gap in the wedge of the insert are aligned, and the insert is rotatable within the cavity of the post such that rotation of the insert will misalign the gap of the wedge with the passage in the post wall such that the wedge prevents the latch pin from traveling through the passage.
