发明名称 Safe removable bollard
摘要 A removable bollard is provided. A bollard is attached to a bollard plate with a catch fixed to one end and a lock juncture fixed near the opposite end of the bollard plate. Additionally provided is a base plate with a catch receiver at one end of the base plate, a retractable latch and a latch receiver at an opposite end of the base plate. The retractable latch has a first position and a second position. In the first position the catch is encompassed by the catch receiver on the base plate to couple with the base plate end, where the retractable latch is then locked to the lock juncture to lock the bollard plate to the base plate. When in the second position, the retractable latch is recessed into the latch recess within the base plate and the bollard and bollard plate are removed, leaving an obstruction-free access way.
