ABSTRACT:
A fan assembly, adapted for easy disassembly for storage and transportation and for easy assembly, includes a housing having a protruding tab-like portion and which is adapted to house a motor and blade assembly. A vertical tapered supporting arm having a narrowed fork-shaped end and an opposite enlarged base end is attached to the housing by having the tangs of the fork-shaped end of the tapered supporting arm adapted to receive therebetween the protruding tab-like portion of the housing. The protruding tab-like portion of the housing and the tangs of the fork-shaped end of the tapered supporting arm, each has a passageway aligned to receive a threaded bolt therethrough. A nut is threadably mated with the bolt to retain the protruding tab-like portion of the housing and the fork-shaped end of the tapered supporting arm in a releasable, selectively positionable compressive relationship. A horizontal base plate member has a hole therethrough with the hole having a cross-section shape similar to that of the tapered supporting arm at a distance proximate the base end of the tapered supporting arm. The tapered supporting arm is adapted to be inserted through the hole in the base plate member and has a taper so that the supporting arm engages the sides of the base plate member forming the hole proximate the base end of the tapered supporting arm. The base end of the tapered supporting arm is releasably attached in a fixed three-dimensional relationship to the base plate member by screws.
