发明名称 Whirligig with articulated frame
摘要 Levered whirligig of the string torsion variety which employs the forces generated by contraction of string torsion device (26) to actuate an articulated frame (10). Articulated frame (10) includes levers (12) and upper struts (18). Levers (12) including handles (16), fulcrums (11) lower struts (14) and hooking member (22) with notches (24). Upper and lower struts are joined together at hinged joints (20), thereby providing an enclosed, articulated frame easily manipulated using a variety of methods. String torsion device (26) includes intertwistable strands (28) and spinning member (30).
