ABSTRACT:
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).
