Claims14
Sunglasses, comprising, in combination:
- (a) a unitary transparent pane located to extend in a curved plane in the path of the wearer's field of vision, both frontally and sidewardly, said curved plane being everywhere substantially cylindrical, the pane having an upwardly humped lower edge bounding a space to receive the wearer's nose,
- (b) a top frame extending along and bounding elongated upper edge extent of the pane, and stems attached to the top frame at opposite ends thereof and adapted to extend rearwardly to the wearer's ears,
- (c) and the top frame having an elongated slot formed to extend upwardly in the frame from the lower side of the frame, along frame length, to removably vertically receive and closely fit the pane upper edge,
- (d) the pane being notched downwardly at two locations respectively proximate the upper opposite ends of the pane, the notches opening sidewardly above opposite end extents of the pane, the top frame having end portions overhanging said notches, and spaced above notch lower edges, said upper edges terminating at said notches,
- (e) the pane including projections overhanging portions of the the notches to interlock within end portions of said slot in the top frame.
