Abstract
Abstract Protective eyewear having a wrap-around type lens and a frame which surrounds the upper and side edges of the lens. The frame includes a slot to receive the lens, and the slot has spaced pawls within the slot. The lens includes mating detents within the face of the lens to receive the pawls and thus retain the lens to the frame. The lateral edges of the frame include upper and lower struts and a bracing bar extends vertically between the struts to define an airflow opening. Rearward of the bracing bar a paint hinge posts extend from the struts in coaxial spaced opposed relation. The temple for the eyewear includes a hinge end having a pivot hole for receiving the hinge posts. The pivot hole includes a cutout with a height corresponding to that of one of the hinge posts, and a width slightly less than that of this hinge post. The temple may thus be mounted and removed from the hinge posts by inserting a first hinge post into the hinge hole, and then snapping the cutout over the remaining hinge post. Where a goggle configuration is preferred, looped ends of an elastic band may be placed over the hinge posts. To increase airflow and/or increase eye protection, a deflector may be removably connected over the airflow opening to guide air behind the lens. The deflectors may be employed with either the temples or the elastic band.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
163 words
In eyewear having at least one lens, and at least one frame section, the improvement comprising: said frame including a pair of hinge pins located adjacent each lateral end of said eyewear, said pins of each said pair extending towards each other generally vertically in coaxial spaced opposed relation; and a temple associated with each said pair of hinge pins, each said temple including a pivot end having a pivot hole receiving an associated pair of said hinge pins, each said pivot end including a cutout at a first longitudinal end of said pivot hole, said cutout having a length slightly greater than, and a projected width slightly less than, said hinge pin extending into said first longitudinal end, whereby said hinge pin extending into said first longitudinal end may pass through said cutout while the remaining hinge pin of said hinge pin pair is received within said pivot hole to allow said temple to be attached to, and removed from, said frame.
Claim 2
Dependent Claim
163 words
In eyewear having at least one lens, and at least one frame section, the improvement comprising: said frame including a pair of hinge pins located adjacent each lateral end of said eyewear, said pins of each said pair extending towards each other generally vertically in coaxial spaced opposed relation; and a temple associated with each said pair of hinge pins, each said temple including a pivot end having a pivot hole receiving an associated pair of said hinge pins, each said pivot end including a cutout at a first longitudinal end of said pivot hole, said cutout having a length slightly greater than, and a projected width slightly less than, said hinge pin extending into said first longitudinal end, whereby said hinge pin extending into said first longitudinal end may pass through said cutout while the remaining hinge pin of said hinge pin pair is received within said pivot hole to allow said temple to be attached to, and removed from, said frame.
Claim 3
Dependent Claim
105 words
The improvement of claim 1, wherein said frame includes end sections mounted at the laterally exterior ends of said eyewear, and further comprising upper and lower struts extending rearward from each said end section, one said hinge post extending from each of said upper and lower struts, and further comprising a bracing bar extending between each of said upper and lower struts substantially parallel to said hinge pins, and wherein said temple includes a wing mounted on a laterally exterior face and extending forward such that said wing will be placed in abutment with said bracing bar when said temple has reached an open position.
Claim 4
Dependent Claim
42 words
The improvement of claim 2, wherein said bracing bars are spaced from said end sections such that said end section, struts and bracing bar each define an airflow opening, and further comprising a deflector removably mounted laterally exterior of each said opening.
Claim 5
Dependent Claim
20 words
The improvement of claim 3, wherein said deflector takes the general from of a plate laterally spaced from said opening.
Claim 6
Dependent Claim
119 words
In eyewear having at least one lens and at least one frame section, the improvement comprising: said frame including a pair of hinge pins located adjacent each lateral end of said eyewear, said pins of each said pair extending towards each other generally vertically in coaxial spaced opposed relation; and an elastic band having a loop at each end thereof, each said loop extending fully about an associated pair of said hinge pins as the only connection between said band and said frame, said band having a thickness such that said loops of said elastic band may pass between said pins of said associated pair to allow said elastic band to be attached to, and removed from, said eyewear.
Claim 7
Dependent Claim
119 words
In eyewear having at least one lens and at least one frame section, the improvement comprising: said frame including a pair of hinge pins located adjacent each lateral end of said eyewear, said pins of each said pair extending towards each other generally vertically in coaxial spaced opposed relation; and an elastic band having a loop at each end thereof, each said loop extending fully about an associated pair of said hinge pins as the only connection between said band and said frame, said band having a thickness such that said loops of said elastic band may pass between said pins of said associated pair to allow said elastic band to be attached to, and removed from, said eyewear.
Claim 8
Dependent Claim
86 words
The improvement of claim 5, wherein said frame includes end sections mounted at the laterally exterior ends of said eyewear, and further comprising upper and lower struts extending rearward from each said end section, one said hinge post extending from each of said upper and lower struts, and further comprising a bracing bar extending between each of said upper and lower struts substantially parallel to said hinge pins, such that said bracing bar serves to limit movement of said loop extending about said hinge pin pair.
Claim 9
Dependent Claim
27 words
The improvement of claim 6, wherein said bracing bar is spaced from said hinge pins a distance to provide a sliding fit for said elastic band loop.
Claim 10
Dependent Claim
47 words
The improvement of claim 9, wherein each said bracing bar is spaced from an associated one of said end sections such that said end section, struts and bracing bar each define an airflow opening, and further comprising a deflector removably mounted laterally exterior of each said opening.
Claim 11
Dependent Claim
20 words
The improvement of claim 8, wherein said deflector takes the general from of a plate laterally spaced from said opening.
Claim 12
Dependent Claim
