11 anims. (c1. 2-14) The present invention relates to goggles and their frames, particularly of a type which are adjustable so as to nt them more accurately to the contour of the wearers face.

Goggles, such as are worn by persons engaged in industries which present hazards to the human eye, have been known for a ,great many years. The types of eye protection provided usually include goggles which consist oi individual eye-cups and a bridge piece, together with lsuitable elastic straps which hold the goggles to 'to put on and remove, it is highly desirable 'to have light weight goggles which,' while they protect the eyes from injury either =by actinic light or by flying particles, will neverthless have some of the characteristics .of the two-piece goggles,

particularly so far as lightness of weight is concerned.

Attempts have been made Ato produce shielding types of goggles which not only have the fea- Ytures of individual, and usually replaceable,

lenses, but which also have side walls or temple `pieces which protect the eye from particles which are approaching at an angle. Such goggles, however, will naturally be rigid and comparatively inexible so that they havea tendency to t inaccurately, and it is only occasionally that the contour of the portion in contact with the wearers brow will have the proper shape to make a 4tight t between the goggles and the'brow.

One of the objects ofthe present invention is to provide one-piece goggles, preferably constructed from a single piece of plastic material, at least the frontal portion thereof being transparent.

A further object of the present invention is to provide goggles in which the bridge member and the temples or sideshields are integral with the frontal portion that serves the function of the separable lenses usually employed in ordinary goggles.

,It is a further object of the present invention to provide goggles having an adjustable bridge member so that they will more accurately t the brow of the wearer, being moreover provided Awith means to make the adjustment permanent once 'the goggles have been properly fitted to the brow of the wearer.

Another object of the invention is to provide goggles or goggles frames in which the bridge member is sectionalized by transversely extending4 cuts orslots so that the various sections may be made to recede from or approach each other at one side,A the frontal lens-carrying portion, which is usually vertically disposed, consisting of some suiciently flexible material to partake of the movement of the sectionalized bridge member.

A furtherv object of the invention is to provide goggles in which the means employed for holding the sectionalized bridge member in condition of proper adjustment also serves a secondary function of holding certain lens members in place.y

Other objects of the invention will become evident from the further description hereinbelow when considered in connection with the accompanying drawings, in which Figure 1 is a perspective view of one form of goggles within the purview of the present invention; v

Fig. 2 is a front elevational view, on asomewhat enlarged scale, of the goggles shown in Figure 1;

Fig. 3 is a top plan view of the goggles shown in Fig. 2;

Fig. 4 is a bottom plan shown in Fig. 2;

Fig. 12 is a perspective view of still another type or goggles; and

Fig. 13 Ais a fragmentary sectional View along the lines |3-I3of Fig. 12.

All of the various types of goggles shown in Figs. 1 through v13 have certain elements in common, as can best be seen from the perspective views constituting Figs. 1, '7 andV 12, namely, in that the goggles consist of a frame having a substantially horizontally 4disposedbridge portion, one side of which is curved approximately to 't the brow of the wearer. The goggles also have side shielding or temple-contacting portions "pieces I6.

which are substantially vertically disposed, and also a frontal portion which is vertically disposed, but substantially at right angles to the plane of the temple portions, and which frontal portion serves to carry either the 1ensmounts of the goggles shown in Figs. 1 and 7, or the single lens of the goggles shown in Fig. l2. In all of these cases, however, the :bridge member iisfdivided into lat least twoksections by means of a transverse-slit or slot which extends about to the frontal portion of the frame.

More particularly, the goggles may, for instance, consist of a frame I4 (see Fig. l) having a substantially horizontally disposed bridge 7portion I which may be formed integrally Jwith the temple portions I6, also having an integral frontal portion II which serves to frsupportlensmounts 8 which may be of the usual construction, or more particularly of the ventilated-type more fully described and claimed in my copend- 'ing I-application iled concurrently herewith.

'The bridgeportion I5 fis-.divided into .two secltioris,I8-and.'I9'frespectively, bya cut or. slot .20 whichextends to-the point'zl which is:substan tiallyat theline of junction of the -`bridge'porftlon JIS with ithe frontal portion I'I. By reason zof #the -flexibility-of the frontal portion -'I'I, the two sections I8 and I9 can be made to approach for recede from each other iin .a lsort .of .pivotal :movement .which has fits :approximate center at lthe'po'int'l. 'Therefore the contour of thebrow- 'contacting edge- 22 can 4be varied .between two extremes,in.other words, froma point where the sections I 8f and' I9 arefsubstantially'touching each 2otherclosing ithe Slot120,1up :to a point where utheyareshown inlthe separated position' best seen in Figs. 3 and 4.

Thegoggles illustrated in"Egs.1through `6 are 'used-in the ifollowing manner: 'With'.the knurled 'nuts '28 'loosened 'so as to permit .free relative vmovement ofthe sections [8 and ,I9..o lthe bridge member I5,'the goggles are appliedto'theface of the wearer and the strap adjusted to a. comfortable position and secured. This will allow the sections I8 and I9 to be adjusted into snug engagement with the wearers brow, whereafter I the knurled nuts 28 are screwed down tightly so as to lock the parts in their positions of adjustment. The goggles having thus been adjusted .an'dma'de-.fast .can be taken :off and laid aside with the-'assurance thatvwhenthey are again ap- 10 lplied to the same head they will accurately t. )This adjustability is of particular advantage zwhenthe goggles are used, for example, by grinders, welders or chippers, as it will insure a, suf- `flciently tightt-between the brow-contacting lI6 portions and-the'wearers brow so as to prevent particlesf-rom entering the interior of the gog- :'gles.

.The goggles illustrated in Figs. 1 through 6 'may'bemade of eitheran opaque or transparent material which may be either a suitable plastic -such as. cellulose-,ester or .'ether, .cellulose'acetate, `cellulose acetobutyrate, ethyl cellulose, .or a transrparent.plastic.material such as av methyl methacrylate resin. fidesiredhowever, .theiparts may Lbemade'of .vulcanized ber or metal.

The lateral edges 'Il and l2 'of the lens member 68 are, however, of reduced thickmess so that a small space may exist between the temple member 66 and the lens member EB to allow for a certain amount of ventilation. Moreover, and for purposes of aillxing the lens member 68, there are provided a plurality, for example four, of S-clips 13, the rearward portions thereof engaging the inwardly bent edges 14 (Fig. 13) of the temple member 66, while the front portion 15 is bent against the outer face of the lens member 68 (see Fig. 13) The bridge member 65 is divided into two sections 'I8 and 19 by means of the slot 80- which terminates at about the point 8| at the point of juncture of the bridge member with the frontal member.

A locking member 83, entirely similar in construction and function to that employed in the' Moreover, by completely unscrewing and removing the nuts 28, the locking member or plate 83 may be removed and the lens then slid out of engagement with the retaining S-clips 13, for repair or replacement of the lens, or said nuts may be simply unscrewed sufficiently to allow the plate 83 to rock upwardly to such an extent as to allow the lensv to slip by the lip 54 of said plate.

All of the goggles illustrated hereinabove described have the common feature of the adjustable bridge portion which is divided into at least two relatively movable sections by a cut extending across said bridge member and terminating substantially at the frontal member. It will be self-evident that more than one slot 20, 50 or 80 may be employed, in which case the bridge member will be divided into more than two relatively trated and hereinabove described may of course subtend a plurality of such slots or slits, it being only necessary that at least two of the sections may be rigidly connected with each other and locked in a position of adjustment bymeans of a locking member 23, 53 of 83.

All of the goggles disclosed herein are characterized by having integrally formed bridge, temple and frontal members, the latter either serving directly as a lens or at least carrying lenses and/or lens-mounts thereon. The temple and bridge members may be either transparent, translucent, or opaque, and the lens portions may be tinted or colored, as may be desirable, depending upon the intended use of the goggles.
