An articulatable barrier for selectively restricting access to a parking space, roadway, passageway or the like. The barrier includes a base and a barrier frame that is pivotally journaled through the base at a pivot axis for pivotal movement of the frame between a first obstructing position and a second nonobstructing position. The base has an aperture formed therein above the pivot axis. The frame carries a center bolt for movement of the bolt between a first lowered position and a second raised position. In the first lowered position, the bolt is received in the base through the aperture, for supporting the frame and for maintaining the frame in the obstructing position. In the second raised position, the bolt is spaced from the aperture and the base for permitting the pivotal movement of the frame. Means is provided for moving the bolt in a second raising direction, wherein the bolt is withdrawn from the base and the aperture being moved into the second raised position. This means also permits the bolt to move in a first lowering position, wherein, when the frame is in the obstructing position, the bolt is received in the base through the aperture.

A barrier for selectively restricting access to a parking space, roadway, passageway or the like, comprised of: a heavy-duty base having an aperture formed therein; a heavy-duty pivotal barrier frame journaled through the base below the aperture for pivotal movement of the barrier frame between a first obstructing position, wherein ingress and egress to the parking space, roadway, passageway or the like is prevented, and a second nonobstructing position, wherein ingress and egress to the parking space, roadway, passageway or the like is permitted; a center bolt having a longitudinal axis, the center bolt being carried by the barrier frame for longitudinal movement of the center bolt between a first lowered position, wherein the center bolt is received through the aperture and into the base for securing and supporting the barrier frame in the first obstructing position and a second raised position, wherein the center bolt is spaced from the base for permitting the barrier frame to pivotally move between the first obstructing and second nonobstructing positions; and key lock means for withdrawing the bolt from the base, so that movement of the lock means in a first direction permits the bolt to move into the first lowered position when the frame is in the first obstructing position supporting the frame in the first obstructing position, and further so that movement of the lock means in a second direction moves the bolt into the second raised position permitting the frame to be selectively pivotally moved between the first obstructing and second nonobstructing positions.
