8 Claims.

This invention relates to goggles and has particular reference to goggles having side shields. One object of the invention is to provide a goggle and a side shield cooperating therewith in an improved manner to provide a ventilatingv passage and to so enclose the passage as to fully protect the eyes against any stray light or against flying particles, whereby the goggle may be used by welders or by chippers.

Another object of the invention is the provision of a goggle and side shield having improved means for detachably mounting and reliably positioning the side shield.

Another object of the invention is to furnish improved means for connecting a side shield to a goggle having a lens securing ring cooperative with the shield to positively lock the connecting means.

Other objects and advantages of the invention will become apparent as the specification proceeds.

With the aforesaid objects in view, the invention comprises the novel features, combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated in the annexed drawings, wherein like parts are designated by the same reference characters throughout the several views.

The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined, but, useful embodiments. may be produced involving less than the whole.

It will be obvious to those skilled in the art to which the invention appertains, that the same may be incorporated in several dilferent constructions. The accompanying drawings, therefore, are submitted merely as showing a preferred exemplification of the invention.

Referring in detail to the drawings, l0 denotes a goggle embodying the invention. The same includes an eye cup ll adapted to fit the face of the wearer, and comprising any suitable air inlet openings l2 of angular or Z-shape in a threaded portion on which is screwed a ring l3,for retaining a lens or glass Id. The ring may partially overlie the openings l2 or form a ballie in front of their external ends while air flows into the eye cup I l and enters the same in a direction against the glass. At its rear outer end. the eye cup may have an opening I5 for attachment of a head band.

Suitable baiiied outlet passages for the air in the eye cup are provided by cooperation of the latter with a shield I6 s0 arranged and constructed that stray light will not enter the eye cup and interfere with the work of a welder. To permit the goggle to be used by a chipper also, the shield is formed with an opening adapted to receive any wire screen button I! as shown in Figs. 5 and 6, for additional ventilation. When used by a welder, the button I! may be replaced by an opaque plug l8 to cut off any light through that opening, as shown in Figs. 1 and 2. The elements I1 and I8 are of course identical in diameter and may be secured in place by a frictional fit or by a screw thread.

Marginally formed on the side shield I6 is a lip H, which is interrupted at 20 to form air outlets, and which merges into a boss 2| as clearly shown in Fig. 5. Confronting each opening 20 is a bafile forming ridge 22, with which cooperate the baffles 23, 24. The baflles 23 extend from the boss 2|, while the baflies 24 extend from the marginal wall l9. At each opening 20, the baiiles 22, 23, 24 coact with the adjacent portion of the marginal wall 19 to form a double zig-zag path permitting ample iiow of air but efiectively preventing any stray light from entering the eye cup through the openings 2|] even if the eye cup or its shield are made of a white plastic. The baffles make uniform contact with the outer surface of the eye cup, the bafiled passages leading to the central region of the shield, which communicates with one or more openings 25 in the wall of the eye cup. If the wire screen buttons I! are used they communicate with;the. central region of the shield and thence with the openings 25 of the eye cup, by-passing the baflle passages. The entrance of dust and flying particles is prevented both by the baflles and by the screen buttons.

To conform to the usual shape of the eye cup,

the shield I6 is of generally triangular shape,

with a base line 26 extending paralleliandfin'close proximity to the lens holding ring I3, andan.

apical portion lying near the rear of the eye cup.

Hence the openings 2!] lie atthe sides ofthe--tri--- angular shield, and the bafiles for one of these openings extend at an angle to the baflles of'the other opening. Sincestheaopenings 25 lie near the top. and. bottom of.- the eye." cup, air: from .all parts of. the. latter is. removed uniformly.

Adjacent to the base-line. 26,.hooksr2] are formed integral with the shield I6; these. hooks being spaced apart to. engage.difierent.portions of. the eye cup, for examplemarginal portions at the ventilating openings 25;. Itii nOtedLthat these hooks project toward the ring lasso that therlatter doesnotform an obstruction. In other words, to connectthe shieldto theeyecup; the shield is movedtoward the ring. 13;. The hooks 2.1 may be further soshaped as to conformtto the inner curved surfaceof the'eyecup. In order to prevent lateral movementofztheshieldialong its plane, the hooks Zlengage near lateral-edges of the openings 25, andrfurther', the: eye cup is provided witha depression which constitutesa seat for the shield. The-edges -of.thisdepression are clearly shown'at 28, 291. inFi'g. 2,- andat' 30.

in Fig. 4, but engagement of the hooks Z'JIis. not interfered with, as the shield [6' is adaptedito be pi-votally moved or swung while the hooks are engaged with the eye cup atthe openings 254 It is noted'that as these hooks project intozthe eye cup atthe forward-end thereof where there: is ample room, they formnoobstruction for vision nor do they interfere with the smooth seating of the eye cuponzthe face of the wearer.

Since the hooks'ZT arelocated at least partially rearward of the base line 26 andfairly'snugly receive the wallof' the eye cup, the shield; I6 is thus secured in place. However, it is-preferred to render the connection'positive as-by providing a hole 3! through theboss Z-iof the shield, whereby a screw 32may be-inserted-into a registering hole in the eye cup, whereby a-connection is provided supplemental to-that of" the hooks 2! and being locatedat asingle, rear. point. Thus the triangular shield'is affixed in apositiye man-- ner adjacent to the three apicalportions'thereof, so as to prevent even a slight separation of 'the shield from the eye=cup.

In Figs. 8 and 9 is showna modification comprising an eye cup Ila and light shield IBa generally like those at II and ifi' except that the screw 32 is eliminated and a positive securement obtained by pressure of thelensholding ring l3 rearward against the forward edge 26a of the shield. At the rear end of the latter is a projection or finger 35 engaged in an opening 36 formed in a raised hollow boss 31; the'opening 36" also receiving the head band 38. T-he'finger 35 actually afiords a'hooked engagement-opposite to that of the hooks 21a, and this'is possible by providing obtained.

that the shield may be slid forwardly to a substantial degree with the hooks 21a engaged and then slid rearwardly to engage the finger 35 in the opening 36, but without disengaging the hooks 21a. In other words, the range of engagement at 21a is greater than that at 35. After such engagement, the ring I3 is tightened to retain the shieldin the: rearwardLposition-and in abutment with the stop portion 3T. Since the thickness of the lenses l4 may vary, some resilience is desirable, and hence the shield may be concaved at its forward edge 26a to contact the ring l3 at spaced points 39, whereby a degree of spring is This is suficient to accommodate lenses of difierent thicknesses and to reliably hold the shield. Thus it is seen that a practical positive connection is obtained without the use of any-screw, and this :is important especially with most. plastics which have little resilience and therefore do not permit the use of spring catches andzthe like.
