Automatic self contained collapsible traffic barrier bollard system

摘要

A collapsible traffic barrier system is disclosed which includes a steel vault having a top treated with anti-skid material. A rod is rotatably mounted to support members inside the vault, wherein the rod extends across the vault from end to end. A plurality of bollards are coupled to the rod substantially near the first end thereof, whereby rotation of the rod rotates the bollards so as to extend the second ends of the bollards above the vault in a vertical direction, or raised position. An actuator having a first end anchored within the vault and a second end is coupled to the rod by means of an arm. The actuator is a worm-drive mechanism disposed for rotating the rod. A stop is anchored to the bottom of the vault for engaging the first ends of the bollards when the bollards are in the raised position.
