are formed separately then joined together using fasteners e g bolts etc interlocking components or features press fitting adhesives welding or any other suitable devices structures or techniques in some other versions attachment portion 14 and angled portion 16 are formed as a unitary construction e g molded as a homogenous continuum of material etc other ways in which attachment portion 14 and angled portion 16 may be formed will be apparent to those of ordinary skill in the art in view of the teachings herein the proximal end 20 of attachment portion 14 is secured to the distal end 30 of fan blade 12 as described in greater detail below in some versions the association of angled fan blade extension 10 to fan blade 12 provides a continuation of the cross sectional profile of fan blade 12 however rather than continuing along the axis of fan blade 12 the association of angled fan blade extension 10 to fan blade 12 creates an upwardly curved angle configured to create a pattern of outward spread in the output airflow column it will be appreciated by those of ordinary skill in the art that other angular orientations may be used along angled portion 16 the aerodynamic properties and angled orientation of angled portion 16 may tend to deflect the air downward and outward in a direction perpendicular to the axis of angled portion 16 of angled fan blade extension 10 such a deflection may create an effect of an outwardly spreading column of air below the fan those of ordinary skill in the art will appreciate.
