Patent ID: RE42941

Claim:
A nose filter comprising: a base assembly; a filter material; releasable attachment means carried on peripheral edge marginal regions of said base assembly for retaining said filter material thereon; a single one-piece U-shaped ear support means pivotally carried on said base assembly for removably retaining said base assembly and said filter material on a facial area; said base assembly includes a pair of rigid plates supporting said filter material and said ear support means; said rigid plates having mated and aligned conformal grooves for pivotally mounting said ear supporting means; said single one-piece U-shaped support means having a pair of support members with each member having a semi-loop at one end and having their opposite ends integrally joined by a rigid pivot bar rotatably mounted in said conformal grooves of said plates; at least one of said rigid plates including a plurality of openings to allow passage of ambient air to said filter material; said filter material is a pad composed of a close-mesh, open cell foam; and said ear supported members are rigidly joined together by said rigid pivot bar and said pivot bar is disposed in rotational relationship in said conformal grooves whereby said ear support member rotates in unison as said pivot bar rotates in said conformal groove.
