Abstract:
1. A barrier device for prohibiting people, vehicles and other machinery from entering a protected space, the barrier device comprising: a metal base plate structure having a bottom surface and a top surface, the base plate structure further having a front edge and a rear edge defining a length; a metal wall plate structure connected to and extending upward from the top surface of the base plate structure, the wall plate structure connected to the top surface of the base plate structure at a location between a mid-point of the length and the rear edge to permanently fix the wall plate structure in a perpendicular position relative to the base plate structure, the wall plate structure including a first side facing the front edge and a second side facing the rear edge; a support structure having at least one triangular metal plate disposed on the second side of the wall plate structure; a metal impact plate structure disposed on the first side of the wall plate structure, the impact plate structure having a plurality of planar sections oriented perpendicularly to the base plate, the planar sections extending from the wall plate structure and connected to one another at an angle to form at least one V-shape pointing toward the front edge; at least one hole extending through the base plate structure, the at least one hole located between the wall plate structure and the front edge of the base plate structure; an anchor member adapted to extend though the at least one hole and into a surface on which the barrier device is placed; and the front edge being a distance from the first side so that when a vehicle impacts the first side, tires of the vehicle will be located atop the base plate structure.
