ABSTRACT:
A small, compact device which, when dropped or thrown from a moving vehicle, opens up and causes a visible flag or marker to be deployed at the upper end of a spring wire originally contained within the device. The device is formed of two mating cylindrical or spherical sections held together by a frangible or easily breakable bonding assembly which will fracture or open under the stress caused by dropping the device and subsequent contact with the ground. While riding or operating a piece of machinery, should a pothole be located or, if for any other reason, should the operator wish to mark a location, he merely drops one of these devices, the unit hits the ground, opens, and the marker deploys.
