Abstract
Abstract Spectacle structure is provided in which a relatively rigid temple of dielectric plastic material is secured to the spectacle frame and is provided with generally vertically grooved or notched configuration as its outer end whereby very slight pressure against the ends of the temple will cause deflection thereof transversely toward the wearer. A resilient band material is secured to the outermost ends of both temples of the spectacle and is intended to surround the head of the spectacle wearer. Substantially all metal components have been eliminated from the spectacle and the resilient head band means provides a featherlight, extremely yieldable, structure minimizing lateral pressure of the spectacle temples and nose bridge against the wearer. Novel resilient band configurations are provided assuring simple resilient band adjustment while at the same time providing extreme flexibility and yieldability of the device.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
In combination in a spectacle having a frame carrying lens means and a pair of plastic temples pivoted thereto, each said temple having a longitudinal length extending generally horizontally beyond the ear of the wearer, the Portion of each temple adjacent the frame being generally stiff, and means rendering the other end of each temple flexible in the horizontal direction toward the wearer''s head, said means comprising a flexible plastic portion of substantially reduced thickness in the horizontal plane permitting localized flexing of said temple adjacent said other end, and resilient band means connecting the said other ends of the temple to each other urging the said other ends of the temples snugly against the wearer''s head while simultaneously urging the spectacles rearwardly of the wearer''s head.
Claim 2
Dependent Claim
127 words
In combination in a spectacle having a frame carrying lens means and a pair of plastic temples pivoted thereto, each said temple having a longitudinal length extending generally horizontally beyond the ear of the wearer, the Portion of each temple adjacent the frame being generally stiff, and means rendering the other end of each temple flexible in the horizontal direction toward the wearer''s head, said means comprising a flexible plastic portion of substantially reduced thickness in the horizontal plane permitting localized flexing of said temple adjacent said other end, and resilient band means connecting the said other ends of the temple to each other urging the said other ends of the temples snugly against the wearer''s head while simultaneously urging the spectacles rearwardly of the wearer''s head.
Claim 3
Dependent Claim
31 words
The spectacle set forth in claim l wherein said resilient band means comprises a light weight yieldable rubberlike material providing only light tension when said spectacles are positioned on the wearer.
Claim 4
Dependent Claim
155 words
In combination in a spectacle having a frame carrying lens means and a pair of temples pivoted thereto, each said temple extending generally horizontally and having a longitudinal length extending beyond the ear of the wearer, the portion of each temple adjacent the frame being generally stiff, and the other end of the temple being provided with vertical grooves facing the wearer and rendering the other end of the temples flexible in the horizontal direction toward the wearer''s head, resilient band means connecting the said other end of each temple to each other urging the said other end of the temple snugly against the wearer''s head while simultaneously urging the spectacles rearwardly of the wear''s head, each of the end portions of said band being on the order of 0.060 inches in diameter and being provided with a plurality of larger diameter spaced integral projections for positive cooperation with retaining means on said other end.
Claim 5
Dependent Claim
155 words
In combination in a spectacle having a frame carrying lens means and a pair of temples pivoted thereto, each said temple extending generally horizontally and having a longitudinal length extending beyond the ear of the wearer, the portion of each temple adjacent the frame being generally stiff, and the other end of the temple being provided with vertical grooves facing the wearer and rendering the other end of the temples flexible in the horizontal direction toward the wearer''s head, resilient band means connecting the said other end of each temple to each other urging the said other end of the temple snugly against the wearer''s head while simultaneously urging the spectacles rearwardly of the wear''s head, each of the end portions of said band being on the order of 0.060 inches in diameter and being provided with a plurality of larger diameter spaced integral projections for positive cooperation with retaining means on said other end.
Claim 6
Dependent Claim
195 words
In combination in a spectacle having a frame carrying lens means and a pair of plastic temples pivoted thereto, each said temple having a longitudinal length extending generally horizontally beyond the ear of the wearer, the portion of each temple adjacent the frame being generally stiff, and means rendering the other end of each temple flexible in the horizontal direction toward the wearer''s head, resilient band means connecting the said other ends of the temples snugly against the wearer''s head while simultaneously urging the spectacles rearwardly of the wearer''s head, said band comprising a readily yieldable rubberlike material providing light tension when said spectacles are positioned on the wearer, and being mechanically secured to the respective temples by physical deformation of said bands at the ends thereof to stretch the said ends to resiliently reduce the thickness thereof into a pinched restraining condition relative to a retaining slot in said temples, said band further having the intermediate portion between the ends thereof constructed of a substantially reduced cross-sectional diameter whereby tensions applied by the application of the spectacles to the wearer stretch said band mainly in the intermediate portion thereof rather than at the ends.
Claim 7
Dependent Claim
