Tire deflating blade perimeter protection system

Abstract

A tire deflating blade perimeter protection system having a control box in communication with a plurality of interconnected modules, each module being a base block with a plurality of blades pivotally connected to a center shaft such that the blades rotate between an armed, up, position and a retracted, down, position wherein the height and angle of the blades in the armed position are adjustable. Each blade is disposed in a blade aperture in the base block wherein the blade aperture is open through the base block to allow for the passage of dirt and debris through the module. A control box ramp is adapted to be placed over the control box as means of protecting the control box from an on-coming vehicle. An extension assembly connecting the control box to the modules extends and raises the control box in relation to the modules.
