Abstract: Disclosed is a self-contained, pop-up bollard barrier system (10) that is capable of working from a single electromechanical actuator (29) with a series of belts (30) and pulleys (38, 38A). The system (10) is built in two parts that once the foundation vault (44) is in place, the internal apparatus or bollard assembly (11) can be removed as a unit for maintenance or can be completely replaced with another assembly to have a brand new barrier without the need of replacing or moving any of the initial foundation. The system (10) enhances the ability of the contractor on site to have a self contained product that only needs wiring and requires no grease while minimizing the installation cost, which is passed on to the end user.

Abstract: 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.
