This invention relates to spectacle goggles which are intended for preventing accidents to the eyes by flying splinters, sparks or the like as well as by detrimental flashes of light as aris*5 ing in welding iron or in the furnaces used for industrial purposes or the like. The object of the invention is to improve on goggles of this type by providing a relatively simple and at the same time robust construction for the individual component parts together with a ready interchangeability for the lenses and other parts.

This is accomplished in the goggles according to the invention by mounting the eye cups that are made of compressed material in a wire frame which holds the lenses in a detachable manner and which is provided with lateral staples to which an elastic fastening band is directly secured.

Even though eye cups that are made of a material such as ebonite, bakelite or the like are not of a strength equivalent to that of metal cups, goggles of this construction present sufficient resistivity since the wire frame takes the mechanical strain resulting from connecting the lenses to the eye cups and from fastening the goggles on the head.

Advantageously, the rear edge of each eye cup, at the portion thereof which, in wearing the goggles rest against the face, is correspondingly curved, so that, with the exception of a slot that may preferably be provided on the outside for the reception of the ear straps of correcting glasses, the eye cup is a close fit all around the same.

For increasing the protection afforded to the eye and to the lens, the front edge of the eye cup may be extended beyond the edge of the lens, the ventilating gap formed between the eye cup and the edge of the lens, which is suitably supported at a few points only, thus being laterally shielded all about the lens, in order to prevent splinters from protruding through this gap.

In the accompanying drawing a form of the invention is shown by way of example only, in which Fig. 1 shows a front elevation of the goggles, partly in section on the line I-I in Fig. 2, Fig. 2 shows a side elevation of the goggles with the fastening band omitted, Fig. 3 shows a larger scale section through the eye cup on the line III-III in Fig. 1; Fig. 4 is a section on the line IV-IV in Fig. 1, Fig. 5 is a section on the line V-V in Fig. 1, and Pig. 6 is a perspective fragmentary view of an exterior rim on the eye cups taken at a portion 5 of the rim for connecting the lens.

Referring to the drawing, the goggles are provided with two eye cups I made of a compressed material and having a circular contour when lakes in the plan. The rear edges of the eye cups are curved in a search manner that each edge follows precisely the configuration of the face, the outer portions of these edges above the temples being the highest and provided with a rectangular notch la. These notches serve for receiving the ear straps of correcting eye glasses for spectacled users.

For preventing the eye cups from cutting into the skin, the cups are provided with an outwardly projecting bead Ib all about the curved rear edge, thus providing for a broad bearing surface of the eye cups and consequently avoiding paining at the contacting portions of the goggles after long use, while at the same time the wall thickness is extremely small with a view to saving weight. The front part of the eye cup is broadened so as to form the exterior hollow rim Jo at the rear side of which a groove Id for the accommodation of a wire frame is formed. The front edge of this hollow rim is provided with three circumferentially equally spaced incisions, le and projections If that are situated inwardly of these incisions at the side thereof, for supporting the lenses G, as well as flanges Ig for centering the lenses. In this manner an open ventilating gap is formed all about each lens, the diameter of which is slightly smaller than the inner diameter of the edge of the hollow rim, as well as underneath the lenses, as will be seen in Fig. 3.

Referring to the notch la, the side wall is provided thereat with a recess ih extending to the. the bottom of the groove Id (Figs. 2 and 5). The wire frame is provided with a central yoke 2a (Fig. 1) which joins with the two annular holders 2b for the eye cups, the open end of these holders being bent in a hook so as to form a detachable connection with the yoke. Each annular cup holder is provided with three forwardly projecting inturned clips 2c which enter into the incisions in the edge of the hollow rims, thus securing the lenses G in position. Immediately at the side of the exterior clip below the latter, the annular cup holder forms to the obliquely outwardly projecting staple 2d to which the fastening band B which consists of elastic material is secured.

For interchanging one of the lenses, it is only necessary to depress the staple 2d from the position shown in full lines in Fig. 4 into that indicated by chain dotted lines. Consequent on this depression, the clip 2c is moved out of its full-line position into the chain dotted position, thus releasing the lens G so as to permit of removing the same as indicated in chain dotted lines. On re6 lease the staple 2d after having inserted a fresh lens, the clip 2c forces this lens into position of use on the respective eye cup.

Since the wire frame is bent up from a single piece of material, the manufacture of the frame is considerably facilitated and cheapened and as the frame is devoid of soldered connections and the danger of disruption is reduced to a minimum. r ur-thermore, a frame of this construction is very elastic, thus adapting itself readily to the config15 ing of the face. Moreover, for securing the lenses in position, no special annular clamps or the like are required that easily become lost.
