A dryer extension assembly connects with a hand-held dryer for dispensing heated air beyond an exhaust outlet of the dryer. The extension assembly is constructed from one or more interconnectable tube sections, an adapter section, and a stand section. Each tube section has a plurality of apertures defined through the outer wall and the inner wall for outletting heated air directed through the tube section. The number of interconnectable tube sections essentially enables the user to select an overall length of the extension assembly. The adapter section couples the dryer to a first or top tube section and the stand section receives the last or bottom tube section. The stand section enables the user to stand the extension assembly in a vertical position such that the hand-held dryer is held aloft by the extension assembly.

I claim: 1. An extension that connects with a portable hair dryer for dispensing air beyond an exhaust outlet of the portable hair dryer, the extension comprising: a tapered tube section having a planar, circular, open first tube end, a planar, circular, open second tube end, and a tapered tube bod
I claim: 1. An extension that connects with a portable hair dryer for dispensing air beyond an exhaust outlet of the portable hair dryer, the extension comprising: a tapered tube section having a planar, circular, open first tube end, a planar, circular, open second tube end, and a tapered tube body disposed between the first tube end and the second tube end, the tapered tube body having an inner wall and outer wall defining a hollow channel between the first tube end and the second tube end, the tapered tube body further having a plurality of apertures defined through the outer wall and the inner wall and in communication with the hollow channel, the tapered tube body having a uniform body slope angled toward the second tube end; a frustoconical stand having a planar, circular, open top portion, a planar, circular, open bottom portion, a frustoconical sidewall connecting the top and bottom portions, and a cylindrical tube-receiving sleeve extending orthogonally intermediate the top and bottom portions, the tube-receiving sleeve being sized to vertically accept the second tube end, the frustoconical sidewall having a uniform stand slope angled toward the top portion; and an adapter connected to the tapered tube section, the adapter having a planar, circular, open proximal end, a planar, circular, open distal end, and an adapter body disposed between the proximal and distal ends, the adapter body comprising a shouldered portion for shoulder-reducing the diameter of the adapter body intermediate the proximal and distal ends wherein the proximal end removably receives the exhaust outlet such that the shouldered portion provides stop structure for the exhaust outlet, the distal end being received within the first tube end such that forced air dispelled by the portable hair dryer flows out the distal end, within the hollow channel of the tube section, and out of the plurality of apertures. 2. The extension of claim 1 further wherein the tube-receiving sleeve is sized to vertically accept the second tube end for axially aligning the connected adapter and the tapered tube section so as to position the connected tapered tube section and adaptor such that the heated forced air dispelled by the portable hair dryer flows axially out the distal end, within the channel, and radially out of the plurality of apertures. 3. The extension of claim 1 wherein the plurality of apertures are staggered along the tube body. 4. The extension of claim 1 wherein the plurality of apertures are staggered in a uniform pattern along the tube body. 5. The extension of claim 1 wherein the adapter removably connects with the first tube end. 6. The extension of claim 1 wherein the adapter fixedly connects with the first tube end. 7. The extension of claim 1 wherein the tapered tube section includes a plurality of tapered tube sections such that each tube section respectively has a first tube end, a second tube end, and a tapered tube body disposed therebetween. 8. The extension of claim 7 wherein the first tube ends each comprise a tapered inner diameter and the second tube ends each comprise a tapered outer diameter, the tapered outer diameters of the second tube ends being receivable by the tapered inner diameter of the first tube ends for removably interconnecting adjacent tube sections such that adjacent tube sections can be readily engaged and disengaged in knockdown relation for ease of storage. 9. An object drying method, the method comprising the steps of: removably connecting together a plurality of tapered tube sections, each tube section having a first tube end, a second tube end, and a tapered tube body disposed therebetween, each tapered tube body having a plurality of apertures defined there through; inserting a lowermost second tube end into a cylindrical, tube-receiving sleeve of a frustoconical stand to vertically support the connected tapered tube sections; connecting an adapter to an uppermost first tube end of the connected tube sections; connecting an exhaust outlet of a portable hair dryer to the adapter; and discharging heated air axially through the exhaust outlet, within the tube section, and radially out through the apertures and onto an object for drying the object. 10. The method of claim 9 further comprising extending the tapered tube section by connecting another tapered tube section to the tapered tube section connected to the adapter.
