Diffuser for hair dryer

Abstract

Diffuser attachment for hair dryer with a collar and a flared hollow diffuser head. The collar is fixedly attached to the diffuser head. The diffuser head is constructed of semi-rigid molded plastic and includes a plurality of air releasing apertures. The collar, partially comprised of an elastomeric plastic capable of being flexed and deformed by a user. The collar is oval shaped in plan view in its relaxed position. The collar is capable of being deformed by a user into a circular shape to facilitate attachment of the diffuser to a hair dryer nozzle. The collar is capable of tensionally and frictionally remaining in place on the nozzle of the hair dryer when the user releases the collar, conforming to the nozzle, after attachment.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]Not ApplicableSTATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableDESCRIPTION OF ATTACHED APPENDIX[0003]Not ApplicableBACKGROUND OF THE INVENTION[0004]This invention relates generally to the field of hair dryer accessories and more specifically to a diffuser for a hair dryer.[0005]Hair Dryers are commonly used to assist people in drying their hair quickly. They are electric devices that blow hot air onto a users wet hair to facilitate drying.[0006]An additional feature that can be attached to a hair dryer is a diffuser device. Diffusers generally have a flared head with a plurality of small apertures that spread the hot air that exits a hair dryer so that the warm air reaches a greater surface area of the head. The hot air is diffused and therefore does not create a hot spot on the user's head during use.Current diffuser heads tend to be designed specifically for a particular hair dryer. The collar portion o...

AI Technical Summary

Benefits of technology

[0008]The primary object of the invention is to provide a hair dryer diffuser that can be easily attached by a user to a hair dryer nozzle.

[0010]Another object of the invention is to provide a hair dryer diffuser that can be tensionally and frictionally held in place on the nozzle of a hair dryer.

[0011]A further object of the invention is to provide a hair dryer diffuser that is compact and can easily be carried while traveling.

[0012]Yet another object of the invention is to provide a hair dryer diffuser that is easy and economical to manufacture.

Problems solved by technology

A deficiency in the prior technology is that most existing diffusers are rigid in construction and therefore will not necessarily fit on hair dryers having an external nozzle diameter that is different from the internal diameter of the collar of the diffuser.

A number of patents have tried to address this problem including U.S. Pat. No. 4,230,279, U.S. Pat. No. 4,295,283, U.S. Pat. No. 4,590,687, U.S. Pat. No. 4,848,007, U.S. Pat. No. 5,036,601, U.S. Pat. No. 5,275,339, U.S. Pat. No. 5,303,483 and U.S. Pat. No. 5,649,370, however, none of these patents allow the user to physically deform an elastomeric plastic collar from an oval plan view shape to a circular shape and then to slide the collar onto the hair dryer nozzle and release the collar so that it tensionally and frictionally engages the outside diameter of the hair dryer nozzle conforming to the shape of the hair dryer nozzle.
