7 Claims. (Cl. 2-1`4)- This invention relates to goggles such asl for use in industry for welding, burning, chipp'ingf and the like;

The principal object of this invention is to provide' an improved goggles having a pair of lens box'es wherein the' lens' boxes are secured together by' a brid'ging device, wherein the lens boxes are adjust'ably" carried by the bridging device for rotat'ion substantially' im one plane and for movement substantially normal' to said` plane closely to fit the face of the wearetf,v an'di' whe'reitrV the desired adjustments of the lens' bones` may bey read'ily and simply accomplished without the* use of tools.

Eriefly, the goggles of this inventi'on include al pair of' separate lens boxes wherein each lens: box has; a mar' ginal rearwardly extending fla'nge.p'ortioni` tot'the' face: of the wearer and a frontal' portion4 including a forwardly extending annular lensv receiving fian'ge provided with'l a' reduced diameter portion' adjacent. the frontal portion. A bridging device is provided. for adjustably eonne'cting together the separate lens boxes. This brld'gingf. device includes a ring portion receivedV in.v the reduced dameter portion of the lens receiving flange of each lens box and a bridge portion connecting together' thef rinn por'- tions whereby the lens bones are: a'djusta'bly? rotatably carried by the bridging deviceV closely' to fitf the face of the wearer.

Preferably, the ring portions` of the' bridging: dev-ice are split and provided at their? ends with. inte'rlocking means so that the ring portions may be" applidfinf spread condition over the lens receiving: flangesioff the lensv boxe's and then interlocked' in'V closed' positionx in.` the redil'ced diameter portions` the'reof. Thisl greatly fa'ciliit'ates the manufaetnre and assembly of' the' gog'gles. Also; the bridge port'ion of the bridging` device isfipreferablyfbend'- able to provide further adjustrnent4 of; the` goggles. t`o1= fit closely the face of the wearer.

The lens receiving flangesi of the: lens boxes are'V` prof; erably provided with external screw threads forreceiving screw threaded' rings for clamping, the lenses. in place on the lens receiving an'ges; These screw threarled rings extend adjacent toV the ring: members? to:v prevcnt unlocking of the interlockingz meanson the1ringzportions of the bridging member but at the. same time' they do vnot clamp the ring portions so that the lens boxes'may at all times be freely rotatedl Withrespecttothe'bridging device.

Further objects of thisA invention reside in the details of construction of the goggles andI in the cooperative relationships between the component parts ther'cof;

Other objects and advantages willi become' apparent to those skilled in the art upon reference tothejaccompanying' specification, claims and drawing, in which:2

Figs. 6'and 7` are front elevational views of thel goggles of' this'A invention illustrating the same in two different adjutedv portions;

VFig. 8 is'an enlarged partial sectional view' illustrating the strap and buckle arrangement for elfectively brid'ging or` closing" the space` between the` lens boxes'. The' goggles ofl this invention is generally designated at 10 and it includes a pair of lens boxes 11 which may be= form'ed of any suitable material suchV as Synthetic plastic or the like. Each lens box 1'1v includes a m'arginal rearwardly extending flange portion 12 for" enga'ging the face of the wearer and also av frontal' portion- 13.- The marginal'rearwardly' extending flang'e portion 12 is provided with an ear 14 having a suitable'openin'g'IS` in which is` secured a head band 16 for'securing the goggles to the facel` and head of the Wearer.

The fi'ontal portion 13 of each lens box 11 is provridedl with a forwardly' extending annular lens receiving ange 1'8' having a forward' annula'r' lens seating surface 197 which may be' provided with1 staggcred ventilating openngs. This forwardly extending annular lens receiving portion 18' is preferably'externally provided with screw threads 20; and adjacent to the frontal portion 113? and' be'- tweerr the frontal' portion" and the screw threads 20; it is also provided? with a reduced diameter portion 21'. The month' of' the lens receiving fl'ange 18`` may be provided with' a' reinforcing ring 212inbedded therein for strcngtheningthe same. A single lens 23; or a plurality of lenses ifdesiredi overlie the annular surface 19 of thelens receiving flzange 1:8A and' the lenses are clamped44 tol the lens receivingV flange 181by a l'ens retainin'g ring 24.' This lens retaining ring'` 221 includes al flan'ge 25 for e'ngaging the lenses 23 and' alsoV screw threads 26' for engaging the screw threads 20 of'the lens receiving flange 18. In this way, the* lenses 23` are readily removably secured" in' place on the lens boxe's 11.

The lens bo'xes' 1'1 are adjustably connectedV together by a* bridging device 28 which` may be formed of any suitable'm'aterial such asV aluminum or the like. The bridge member 28 includes a pair' of ringV portions 2'9' connected together by a bridge portion- 30. Each ring portion 29 is split as indicatedv at 31 and-l the ends of each ring portion are providediwith an` nterlocking means such as adovetail'i ih'terl'ocking means including a male portio'n 32 and a femaleiportion 33. Theseporti'ons 32' and 33 are laterally displaceable so that the ringportions 29 maybe spread apart as indicated; in Fig. 4 or closed and interlocked' as indicated in Pig. 5.

The ring portions 29 are spread apart and applied over the screw threads 20 of the lens receiving flanges 18 and are thenv closed and interlocked in the reduced diameter portions 21. In this way,r the lens boxes are firmly secured to the bridging device and are freelyV rotatable therein sol that the lens boxes may be rotated to any desiredr position, as illustrated in. Figs. 6 and: 7, closely to fiti the face of the wearer. The lens retaining rings 24 lie closely adjacent'. to the ring portions 29 of the bridging 'device 28 and they operate to preventaccident-al lateral ldisplacement and unlocking of the interlocking means. At the same time, they do not engageor clamp the ring portions 29 so that the' lensz boXes may at` all times be freely rotated to the desired adjusted positions. The bridging portion 30 is bendable so that' the lens boxes may be fnrther adjnsted in order closely to fit the face of the weaner;

To close the space between the lens bo'xes to prevent entrance of foreignl matter therebetween, the adjacent edges of the frontal portions 13 of the lens boxes are provided with slots 35 for receiving a flexible strap' 36 such as a leather strap. The strap is adjustably secured in place by a buckle 37.

Thus, it is seen that the lens boxes 11 are permanently secured together by the bridging device 28 and the lens boxes may be completely adjusted to fit the face of the wearer. The lens boxes may be readily replaced by merely manipulating the interlocking means on the ring portions 29 of the bridging device 28. The lenses 23 may also be readily replaced merely by manipulating the lens retaining rings 24 and in so doing this has no effect upon the bridging device which connects together the lens boxes.

While for purposes of illustration one form of this invention has been disclosed other forms thereof may become apparent to those skilled in the art upon reference to this disclosure and, therefore, this invention is to be limited only by the scope of the appended claims.
