ABSTRACT:
A collapsible barrier for controlling vehicular access to parking areas and transitways, comprises a base and an elongated post hinged to the base. A first latch member fixed to the base engages a second latch member to secure the post in an upright obstructing position. The second latch member is located within the post and hinged to rotate about an axis parallel to the post hinge axis. An actuator, accessible from the exterior of the post, swings the second latch member in a direction to disengage it from the first latch member. A spring, operating in conjunction with camming surfaces on the latch members, provides for automatic reengagement when the post is rotated into the obstructing position.
