发明名称 Flying toy
摘要 A launcher (20) for a flying object, such as a boomerang (21), having a body that includes a plurality of wings (31). The launcher includes a stop (23), against which the object rests at a point (27) on its body. A moving member (25) engages one of the wings of the object so as to impart forward motion thereto, such that the object is propelled forward from the launcher with a rotational moment about the stop. The boomerang is preferably made from a sheet (50) of material which is cut to form the plurality of wings, joined at a vertex (28), wherein one or more of the wings are folded to produce lift flaps (34, 35).
