Abstract: An improved sign post assembly (10) for roadway use is provided wherein a sign post (12) includes a lower section (16) adapted for anchoring to the earth, a mating upper section (20) and a magnetic coupling assembly (24) for maintaining the sections during normal use while permitting breakaway of the upper section (20) when the host (10) is struck by a vehicle. Preferably, the coupling assembly (24) includes a magnetic body (26) and a corresponding component (28) which is magnetically attracted to the body (26). In order to cause breakaway in a predetermined direction, the coupling assembly (24) has mating surfaces for the body (26) and component (28) which are in a stairstep configuration.

Abstract: An aerodynamic toy (20) comprises a flight body (22) including an enlarged portion (30) and an airfoil portion (32); the body (20) is preferably generally samara seed-shaped. A launching device (24) is used to propel the body (22) into the air for spiral-type autorotation descent. In other forms, the body (22) may be equipped with a battery compartment (68) allowing insertion of a battery (74) in order to illuminate spaced lights (60) carried by the body. A whistle (82) or other noise maker may also be fixed to the body (22) to emit a sound during flight.
