Abstract

A face shield assembly is releasably attached to a pair of spectacles and is adjustable so that it may be placed close to or away from the wearer'"'"'s face. It is lockable into each position of adjustment. Multiple apertures are formed in a clear or tinted lens, just below its uppermost edge, and these apertures press fittingly receive posts that are formed along the length of a flexible base member that conforms to the contour of the wearer'"'"'s head so that the lens depends from the base member. The opposite ends of the lens are retained in detent members formed in the opposite ends of the base member, and a horizontal top shield extends from the base member to the wearer'"'"'s forehead.

Claims

1. A face shield assembly, comprising:

a flexible base member;

said base member having a curvature formed therein so that it follows the contour of a human head;

a plurality of posts spaced at predetermined intervals along the length of said base member;

a flexible shield means;

a plurality of apertures formed in said flexible shield means near an uppermost edge thereof so that said flexible shield means is detachably secured to said base member by press fitting said posts into their associated apertures;

a top shield means having a leading edge that conforms to the curvature formed in said base member and that is fixedly secured thereto, said top shield means substantially closing a space between the base member and the user'"'"'s forehead when the face shield assembly is worn;

a clamp means that detachably engages a pair of spectacles having lens means; and

engagement means for releasably attaching said top shield means to said clamp means;

detent means at opposite ends of said base member for releasably retaining opposite ends of said flexible face shield against said base member so that the shape of said flexible shield means conforms to the shape of said base member; and

said engagement means including means for slideably engaging said top shield means and for engaging said clamp means so that said flexible shield means may be placed at differing spacings relative to the face of the user of said face shield.

2. The face shield of claim 1, wherein said engagement means further includes a flat plate secured to said top shield in overlying relation thereto at a bight region thereof.

3. The face shield of claim 2, wherein said engagement means further includes a pair of transversely spaced apart channel-defining members fixedly secured to an underside of said top shield means so that said top shield means is disposed in sandwiched relation between said flat plate and said channel-defining members.

4. The face shield of claim 3, wherein said engagement means further includes a pair of transversely spaced apart "L"-shaped flat members, each member of said pair of flat members having a leading end and a trailing end, each leading end being disposed substantially orthogonally with respect to its associated trailing end, and each of said leading ends being slidably disposed within an associated channel-defining member of said pair of channel-defining members.

5. The face shield of claim 4, further comprising a first bridge member for interconnecting the leading ends of said flat members, and a second bridge member for interconnecting the trailing ends of said flat members, said first and second bridge members also maintaining the transversely spaced relation between said leading and trailing ends, respectively.

6. The face shield of claim 5, further comprising a flexible platform member disposed between said leading ends in parallel, coplanar relation thereto, and a hollow, hemispherical protuberance formed in a top surface of said flexible platform member, and further comprising a plurality of complementally formed protuberances formed in a top surface of said flat plate in linear array so that said flexible shield means is lookable into a plurality of functional positions of adjustment relative to a user'"'"'s face.

7. The face shield of claim 4, further comprising a trailing flange formed in a trailing end of each of said flat member leading ends to inhibit rotation between said leading and trailing ends of said "L"-shaped flat members.

8. The face shield of claim 5, further comprising a clip means releasable mounted to said second bridge member, and a bias means for biasing said clip means to clampingly engage said pair of spectacle lens when said clip means is in repose so that said face shield is supported by said pair of spectacles.

9. The face shield of claim 8, wherein said clip means includes a pivotally mounted plate having a pair of transversely spaced apart depending legs, wherein said clip means includes a pair of lens-engaging members, each lens-engaging member of said pair of lens-engaging members being fixedly secured to an associated leg of said depending legs so that pivotal movement of said plate is imparted to said lens-engaging members, and said bias means biasing said plate and hence said lens-engaging members into engagement with said lens when said bias means is in repose.

10. The face shield of claim 9, wherein each of said lens-engaging means has a bulbous distal free end so that said lens are not scratched when said bias means is in repose.

11. The face shield of claim 1, wherein said shield means is clear.

12. The face shield of claim 1, wherein said shield means is tinted.
