Abstract
A family of eye protectors for use with a variety of shapes and sizes of heads includes a plurality of different lenses with each lens having a selected curvature and selected height and profile parameters; and a manually adjustable nose engaging element carried on each lens. The nose engaging element can include a substantially U-shaped frame which has first and second deflectable, spaced apart members joined by a third member. A plurality of identical mounting elements can be proved wherein each mounting element holds one of said plurality of different lenses.
Claims11
A family of eye protectors comprising:
- a plurality of different unitary lenses with each lens having a common curvature and a different profile parameter;
- a set of temples where the temples are at least one of rotatably adjustable relative to the lens, or, slidably adjustable relative to the lens;
- each lens having a different size nose securing region;
- and
- said family having one manually adjustable nose engaging element that can be carried on each of said plurality of different unitary lenses where each lens defines an adjustable nose element receiving slot;
- wherein the adjustable nose engaging element includes a slidable lens engagement member which lockingly engages the respective lens at only a plurality of spaced apart locations;
- wherein the eye protectors are frameless and
- wherein the nose engaging element includes two separate, double molded nose contacting pads formed of two different elastomeric materials co-injected on a nose bridge producing pivotable ball joint-type movement.
Safety glasses comprising:
- a plurality of different sized unitary lenses, the lenses have a common curvature, each lens has a height and a length parameter which are consistent with a user face shape selected from a class that includes a wide face, a narrow face and a large face;
- a set of temples where the temples are at least one of rotatably adjustable relative to the lens, or, slidably adjustable relative to the lens
- one manually adjustable nose engaging element that can be carried on each of said plurality of different sized unitary lenses, and
- where each lens defines a manually adjustable nose engaging element receiving slot;
- wherein the manually adjustable nose engaging element lockingly engages the respective lens at only a plurality of spaced apart locations;
- wherein each lens has a different size nose securing region;
- wherein the adjustable nose element includes a slidable lens engagement member;
- wherein the safety glasses are frameless and
- wherein the nose engaging element includes two separate, double molded nose contacting pads formed of two different elastomeric materials co-injected on a nose bridge producing pivotable ball joint-type movement.
