US Patent 7637226 Emergency flag apparatus and associated method

An emergency signaling apparatus includes a portable base member, a telescopically adjustable and rectilinear pole, a plurality of brackets, and a flag directly coupled to the brackets and adaptable between compressed and expanded positions when the brackets are displaced along a longitudinal length of the pole. A mechanism is included for simultaneously articulating and linearly displacing the pole about at least two mutually exclusive axes respectively in such a manner that the flag is automatically returned to an equilibrium position defined along a vertically oriented plane after being biased about the at least two mutually exclusive axes.
