Abstract

PURPOSE: To allow an electric fan to swing by a pinion gear rotating around a rack of approximate elliptical form with a simple mechanism consisting of a small number operational parts.
CONSTITUTION: When a rotor axle 2 drives and rotates a vane 20, a pinion gear 8 revolves through a spring 9. Once the pinion gear 8 starts turn, it rotates and moves along a rack 7 meshing each other successively permitting a fan motor 1 to turn around a support axle 3. Upon arriving at the end of the rack 7, the pinion gear 8 engages with the rack 7 on the bottom side of the rack main body permitting the fan motor 1 to turn in reverse direction to the above. Thus the pinion gear 8 meshes with rack 7 on the elliptically formed portion and keepts its rolling motion allowing the fan motor 1 to swing right and left. The swinging unit consists of major components such as the spring 9, the pinion gear 8, the rack 7, and offers swinging motion of an electric fan with a simple mechanism and a small number of operational parts.
