N. Y., a corporation of New York Application October 19, 1940, Serial No. 361,939

5 Claims.

This invention relates to goggles and more particularly it has reference to the bridge member which connects the two eyecups of a goggle.

One of the objects of my invention is to provide an improved bridge member for goggles which will be relatively simple in structure yet efficient in operation. Another object is to provide-a goggle having a flexible bridge member which may be readily assembled and adjusted. A further object is to provide a goggle having an adjustable bridge member which also serves to hold the bezel on the eyecup. These and other objects and advantages reside in certain novel features of construction, arrangement and combination of parts as will hereinafter be more fully described and pointed out in the appended claims.

Referring to the drawing:

Fig. 1 is a fragmentary front view of a goggle embodying my invention.

Fig. 2 is a fragmentary side view of same.

Fig. 3 is a fragmentary top plan view of an eyecup.

Fig. 4 is a horizontal sectional view showing the bridge connections with the eyecups.

Fig. 5 is a view of the nasal side of the eyecup and bezel.

Fig. 6 is a fragmentary top plan view of a modification.

Fig. 7 is a horizontal sectional view of the eyecup of Fig. 6.

Fig. 8 is a view taken on line 88 of Fig. 7.

A preferred embodiment of my invention is illustrated in the drawing wherein l0 indicates,

generally, a goggle having two spaced eyecups I H which are connected by the flexible bridge member l2. The construction of both eyecups is identical and hence a detailed description of one eyecup will be sufificient. The eyecup H is formed so as to fit the contour of the face of the wearer and may be made of any suitable material such as aluminum, molded plastics or the like. A lens l3 rests on the front edge of the eyecup H and it is held in place by the bezel M which has an overhanging lip or side wall 15. The bezel l4 may also be formed of any suitable material such as metal or molded plastics.

On its temporal side, the bezel I4 is secured to the eyecups by means of a pivotally mounted clasp [6 which engages the upstanding lug I! carried by the eyecup II. The clasp I6 is held against accidental opening by the ring I8 attached to the elastic headband l9. The ring l8 passes through an opening, not shown, in the lug l1.

On the nasal side of the eyecup H, the bezel l4 is held onto the eyecup by means of the flexible strap member l2 which also serves as a bridge for connecting the two eyecups of the goggle.

w The nasal side of the bezel I4 is provided with a slot 20 while the nasal wall of eyecup II is provided with the slot. 2! and the notch 22 is formed in the rear face or edge of the eyecup. Both of the slots 20 and 2| and the notch 22 are adja- Figs. 1 and 4, the two free ends 23 of strap l2 are located adjacent the front nasal portions of the eyecups. From this position, the strap extends rearwardly and then into the eyecup through the notch 22 and then outwardly through I the slot 2| in the eyecup wall. The strap is then looped through the slot'2ll in the wall of the bezel I4, is doubled back on itself and. again enters the eyecup ll through slot 2| and then passes out through notch 22 and over to the other eyecup where it is similarly connected, as clearly shown in Fig. 4. V, 7

It will be apparent, therefore, that the strap l2 serves to. hold the nasal side of the bezel M in place on the eyecup and also acts as abridge member to connect the two eyecups. The bridge member l2 'may be readily adjusted so as to vary the pupillary distance between the eyecups in order to fit the face of a wearer. When the two eyecups are moved rearwardly so that the rear faces of the eyecups are brought into contact or in proximity to each other, the parts of the strap l2 are rendered accessible for adjustment purposes. Since the usual buckle member is not required, it is possible to bring the nasal sides of the eyecups into very close proximity so that narrow interpupillary distances may be accommodated.

A modification-is shown in Figs. 6-8 wherein 25 indicates an eyecup of a goggle having a different construction. The eyecup 25 may be formed of molded plastic, metal or any other suitable material. The lens 26 is placed against the front edge of the eyecup 25 and held in position by the bezel 21. The temporal side of eyecup 25 has a groove 28 into which is fitted the bead 29 carried by the temporal side of bezel 21. The nasal side of the bezel 21 is 'held in place by the flexible strap member 30 which also serves as a bridge to connect the two eyecups, both of which are identical in structure.

The nasal side of the bezel 21 is provided with the slot 3| and the nasal wall of the eyecup 25 has the two slots 32 and 33, with slot 33 positioned rearwardly of slot 32. The free ends 34 of strap 30 are positioned between and adjacent the nasal sides of the eyecup 25 and bezel 21. From this position the strap extends rearwardly and into the eyecup through the slot 33 and then out of the eyecup through slot 32. The strap is then looped through the slot 3| in bezel 21, doubled back on itself and extended through slot 32 again and then out through slot 33 and. over to the adjacent eyecup, as clearly shown in Fig. 7. The slot 33 should preferably have a substantial width in a direction perpendicular to the plane of the lens 26 in order to afford ample slack in the strap 30 when making adjustments. Such adjustments in bridge length can be readily made and the bridge member 30 may be unloosened when it is desired to remove the bezel 21 to replace the lens.

From the foregoing it will be apparent that I have attained the objects of my invention by providing a goggle having a bridge member which is simple in structure yet efficient in operation. By my novel construction I have eliminated the necessity of using a separate buckle or strap fastening member. My improved bridge can be assembled and adjusted without the use of tools. If the goggle parts are made of molded plastics, for example, the slots and notches would be formed when the parts were molded so that the cost of providing the adjustable bridge member is reduced to a minimum. Various modifications can obviously be made without departing from the spirit of my invention.

I claim:

1. In a goggle the combination of an eyecup havinga nasal wall provided with a slot adjacent the front edge of the eyecup, the rear edge of said eyecup having a notch which is substantially in alignment with said slot, and a bridge member secured to said eyecup, said member comprising aflexible strap which is doubled on itself and extends from a point adjacent the outer nasal wall of the eyecup through said slot and into the eyecup and then rearwardly and laterally through sa-id'notch to a point outside of the eyecup.
