A parking barrier permanently installed in vehicle parking surface, which has a base (20), with legs (22) embedded within the surface. A hinge plate (28) is attached to the base and allows the barrier to be rotated to a horizontal position permitting a vehicle to safely pass over the collapsed barrier. A channel shaped post (34) is pivotally attached to the hinge plate and a rigid strut (40) is retained on one end within the post and, on the other, to the hinge plate. The strut forms a right angle triangle with the post. A pull pin (46) holds the upper end of the strut in place and when removed, permits the barrier to be rotated horizontally removing the obstruction. A second, or electromechanical, embodiment utilizes a linear actuator (84) for the strut. An electronic controller (100) receives a signal through a coded radio frequency transmitter (102) and receiver (104) and, in turn, energizes the actuator to rotate the barrier into a horizontal position. Limit switches (120) and (122) control positioning and indicator lights (108) and (110) denote the barriers position. The electrical system operates on low voltage direct current supplied by a D.C. power supply (114).

[ What is claimed is:] [1.] A vehicle parking barrier permanently installed within a parking surface for withholding access and maintaining security of a motor vehicle comprising;a base having downwardly extending angular legs permanently embedded within a parking surface,hinge means attached to the base for allowing the barrier to be rotated downwardly from an obstructive vertical position,a pivotal barricade post swivelly attached to the hinge means,a structurally sound strut having a first end and a second end, with the first end slideably retained within the post, and the second end attached to the hinge means, also the post, base and strut arranged in a form of a right angled triangle with the strut constituting a hypotenuse, andlocking means disposed between the post and the strut for removably capturing the strut within the post for inflexible vertical securement while permitting authorized access to pivot the post into a horizontal position by sliding the strut therewithin.
