ABSTRACT:
A battery operated safety strobe barricade, particularly suited for school crossings. The use of a battery pack that is rechargeable and can be separated from the barricade enables the apparatus to be particularly well suited to safety situations where high visibility and weight are considerations. The A-frame stand section is fabricated from low weight aluminum so that it can be carried by even the smallest crossing guard. The rechargeable battery pack features a dual rate charger so that the unit can be left to charge continuously. The battery pack has a low voltage disconnect feature so that catastrophic battery discharge is avoided thus prolonging the life of the battery. A high visibility strobe light mounted on a telescoping pipe enables the unit, despite its light weight construction, to provide a warning beacon that can be easily seen at great distances, even in the daylight.
