Abstract
Abstract An oscillating electric fan having a neck joint which is mounted for tilting movement back and forth on the top of an upwardly projecting portion of a base and a fan unit mounted on top of the neck joint for oscillating movement on the neck joint about a vertical axis includes a flexible clip element which serves to selectively limit the extend of the tilting movement of the neck joint. The clip element, which is attached to the bottom of the neck joint has a hooked shaped tip which will strike the front wall of the upwardly projecting portion of the base when the neck joint is tilted down about 20 degrees from the horizontal axis and as a result prevents further downward tilting movement. However, by manually flexing the clip element upward away from the front wall the neck joint can be tilted further downward so as to place the fan in a collapsed or folded position.
