'I'he invention herein disclosed relates to eyeshields.v n Objects of the invention are to provide a shield which will effectively protect the eyes from glarl ing sunlight, articial light, wind and dust. which will be of simple inexpensive construction, light in weight, comfortable to wear, of neat attractive appearance, foldable to occupy small space, nonbreakable and of a form to fully pro- .0 tect the eyes, without possibility of injuring the same.`

The foregoing and other desirable objects are attained by the novel features of construction, combinations and relations of parts hereinafter .B described, illustrated in the accompanying drawing and broadly covered in the claimv annexed.

The drawing 'shows by way of illustration apresent practical commercial embodiment. of the invention. Details of the construction may however, be modified and changed without departure from the true spirit and broad scope of the invention. I

Fig. 1 is a front View of the eyeshield.

Fig. 2 is a part sectional view as taken onsub-` stantially the plane of line 2 2 of Fig. 1.

Fig. 3 is a broken plan and part sectional view as on the line 3-3 of Fig. 1.

Fig. 4 is a broken vertical sectional detail as on lline 4-4 of Fig. 2. l As indicated' in the vseveral views, the shield consists simply of three pieces of transparent or translucent molded plastic, a front part 5, con-- 'sisting of thin lens simulating portions 6, connected by a thickened arched bridge 1, and hav ing thickened rearwardly extending nose pad projections 8; and two thin side members 9, having inwardly projecting top and bottom flanges I0, II, disposed between and connected by small pivot pins I 2, I3, to rearwardly projecting lugs I 4, I5, at the top and bottom edges ci.' the front portion. I

As shown particularly in Fig. 1, the ends of the front part are'slightly inclined .outwardly and downwardly, giving this part a downward flare and so that with the location of the hinge lugs at the ends or in the end corners ofthe lens constituting elements, the hinge axes will be inclined to thev vertical, thus to locatethe side members at an inclined shielding angle and to cause them to swing downwardly as they fold inwardly behind the front part.

The flanges IIJ and II, stiien and strengthen the thin side shielding members 9, and the upper flange I is shown as of appreciably greater width than the lower, so as to shield the eyes against light from above.

The side members or temples 9, while of substantially the full height of the ends of the front part, taper from this maximum width immediately and continuously toward the rear, into thicker bow forming portions I6. The top and bottom anges and the front thin Wall between the flanges all merge into these thickened bow portions as indicated in Figs. 2 and 3, the latter 10 showing in particular how the thin light shielding Wall is molded inwardly on a gradual curve at I1, into the full thickness of the bow. With such construction, the sides can be made as thin as desirable, the anges providing necessary l5 strength back to the merger into the full thickness of the bows.

`The ends of the temples, including the flanges are shown as nished oft at a sharp right angle and as abutting the back of the front shield, so as to stop and brace the parts in this relation and to prevent entry of light rays at the juncture of the front and side shielding portions.

By molding the device, in plastic, the light shielding parts can be made as thin as desirable and additional thickness be given where strength or bearing surfaces are required. Thus in 'par'- ti'cular, suilicient surface may be provided at the nose pads and in the portions of the bows which 'l go back of the ears to make the device t com- 30 fortably and bear lightly on the wearer.

By locating thehinges -at the'ex'treme ends yand in the upper and lower corners of thelens portions, the eyes are not distracted or bothered' and such hinges arev practically invisible as viewed from V'appearance and provides desirable protection 40 without unnecessary bulk. No metallic parts are required, except possibly for the small concealed' hinge pins. The temples fold flat, one inside the other, behind the front portion. 'I'he wide anges at the top, the narrower flangesl at the bottom 45 and the downward outward slant of the temples provide a desirable awning effect, shutting off direct light from above, while allowing free circulation 'of air below. By molding. the parts, the

material may be placed only where required and A.

the article be thereby kept light and inexpensive.

What is claimed is: An eyeshield, comprising a substantially at front eyeshielding portion having substantially Vertical straight ends, upper and lower rearward said temple portions are in open relation, upper and lower inward horizontal extensions on and perpendicular to sid thin at eyeshielding temple portions adjacent the upper and lower edges thereof and at the inner faces thereof, said upper and lower extensions being spaced closely to em-` brace and to enter between each other at said vertical straight ends, said upper and lower ex` tensions yforming four sets of closely contacting 1 pairs and adjacent the outer upper and lower corners of said vertical straight ends, each of lo said pairs being provided with pivot connections.A
