EMIL B. MEYROWITZ, OF NEW YORK, N. VY., ASSIGNOR T0 E. B. MEYROWITZ, INC.,

CORPORATION 0E NEW YORK Goeenns Application led May 5,

t vMy invention relates to goggles and especially to thatI type of goggle which is service able in aviation and" kindreduses. 1n cer tain respects my invention relates particufv 1d tion for uniting the eyecup and bridge member. Another object of my invention is to provide an improved construction for locking the goggles in a. closed position. Another object of my invention is to provide aV construction in which the locking means for locking the goggle in the closed position may be utilized to secure the cushion in place with respect to the goggle. A further object of my invention is to provide an eyecup for a goggle which may be properly ventilated.

In accordance with my invention, I provide a goggle in which the eyecups areprovided with bearing sockets for the legs of the bridge member. The sockets are split transversely through thebearing socket so that the bearing socket of each eyecup is intwo sections, one section on either side ofthe transverse split in the eyecup. The leg of the bridge member isadapted to expand transversely andvcooperates with thebearing sockets to secure the bridge to they eyecup and to Vmaintain the eyecup in the closed position;

Specifically, the bearing sockets of theeye-v cups are at the nasal end of the eyecups and' are adapted to receive the legs of a bridge member which secures the eyecups together. The legs of the bridge member are so con` structed that theyv expand transversely and when in position inA the bearing sockets,and

A 4the eyecups `are closed7 the legs` expand transversely and secure the eyecups in the closed position. Y- Y' Another phase of my invention relates to' the cushions and the reinforcing bands therefor. The cushions7 one of which'is used vin conjunction with each eyecup, are molded to Aform a seat'for the eyecups, 'and an'out-` wardly extending lip which extends into the` eyecup. -On the inner'surfacegofthe lip,

tons whichnare integral with the cushion.l These buttons are Ladapted to engage openings;

in av reinforcing band to secure the lip of the Y cushion to the reinforcing band. The reinforcing band is also provided with pointed i projections whichpierce the cushion and cooperate with the buttons in holding the cushion tothe band.

The invention also contemplates a construction providing an improved securing means for securing the reinforcing band of the cushion to the eyecup. The reinforcing band has lugs formed at eachend, one vat the temple end and one at the nasal end. One of thesek lugs is provided with an opening, andjis i adaptedy to extend between the sections of the carin-ff socket on the eyecup, the Opening through the lug being aligned with the bearing socket so that the element passing through the bearing socket passes through the lug. rIhe other lug on the reinforcing band passesy through an opening through the eyecup so thatthe reinforcing band is secured to the eyecup at two points. i Another feature of my invention resides in the provision of means to ventilate the eyecupsmThe eyecups are provided with raised hollow-portions at the top and bottom'thereof.A These raised hollow portionseXtend back beyond the lensso as tol form a passage bei tween the lens and vthe edge of the cushion.- The forward wall of the lower hollow portion is provided with a-series of small openings and the rear wall of the upper raised hollow portion is also provided witha series of small openings. Thus, as the wearer of the goggles. moves along, air entersthrough the lower hollow raised portion, moves along vthe inner surface of the goggles and out through the upper raised hollow portion.

Other features and advantages of my invention will be apparent from the following particular description of an embodiment thereof which is' illustrated in the accom-I panying drawings lin which: ,Y Y

In the goggles shown in the drawings, the eyecups 1 are connected together by a bridge member 2 and are identical, with the exception that one is reversed with respect to the other. Each eyecup is provided with a bearing socket 3 formed in the eyecup wall at the nasal end and adapted to receive the legs l of t-he bridge member. The eyecup is split transversely through the bearing socket, dividing the bearing socket into two sections, one on either side of the transverse split. The transverse split in the eyecup permits flexing of the eyecup to insert and remove the lens 5. rlhe lens is mounted in a frame 6 which has an outer flange 7 that abuts against the outer edge of the eyecup, and an inwardly extending flange 8 which is beaded over the edge of the lens at the inner end. This frame member is clamped by the eyecup when the eyecup is in the closed position and is retained in the eyecup by the clamping action thereof.

At the bottom and top of the eyecup, there is provided raised hollow portions 9 and 10 respectively. As clearly shown in Fig. 5, these raised hollow portions extend a substantial distance behind the lens so as to form a passage between the rear wall of the hollow portion and the lens, which passage opens into the eyecup. The forward wall of the lower raised hollow portion is provided with a series of small openings which are adapted to permit air to enter the raised hollow portion. The rear wall of the upper raised hollow portion is likewise provided with a seriesof small openings which are adapt-ed to permit air to be exhausted from the eyecup. Thus, air may enter through openings in the forward wall of the lower raised portion and, by virtue of the curvature of the rear wall of the hollow portion, the air is directed along the surface of the lens to the upper raised hollow portion from which it is exhausted through the openings in the rear wall thereof. Air, passing through the eyecup in this manner, serves to prevent the formation of a mist on the lens of the goggle, which would impaii` the visibility of the wearer. l

Each eyecup is provided with a cushion 11, and as shown in Figs. 7 and 8, the cushion, which is of soft rubber, is molded to form aseat for the eyecup which fits snugly against the eyecup, and an outwardly extending, circumferential lip 12 which extends into the eyecup and engages the inner surface thereof. On the inner surface of the lip 12, there is formed a series of projections or buttons 13. These buttons are also molded and are integral with the lip of the cushion. The buttOns on the inner surface of the lip of the cushion are adapted to cooperate with openings in a reinforcing band, 14 to hold the lip of the cushion to the reinforcing band.

rlhe reinforcing band is made from a single piece of sheet metal and is pressed into the shape of the inner surface of the eyecup. The ends of the strip of metal from which the band is constructed are brought together at the nasal end of the reinforcing band and are bent laterally thereto and form a lateral lug 15. Diametrically opposite to lug 15, at the temple end of the band, there is a lug 16 secured to the outer surface of the reinforcing band. The reinforcing band is provided with a series of openings 17 corresponding to the buttons on the inner surface of the lip 12 of the cushion. These openings are slightly smaller in diameter than the head of the buttons which are adapted to be pressed through these openings to secure the cushion to the band. In addition to the button connection between the band and the lip of the cushion, the band is also provided with a series of inclined pointed projections 18 at the rear edge thereof which extend into the cushion and serve to aid in preventing longitudinal movement of the cushion with respect to the reinforcing band. The lugs at the temple and nasal ends of the reinforcing band extend through the lip of the cushion and are provided with openings for a purpose which will hereinafter appear.

The lug 16 on the reinforcing band at the temple end is adapted to extend through an opening formed through the wall of the eyecup and the lug 15 at the nasal lend is adapted to extend into the transverse split at the nasal end of the eyecup, between the sections of the bearing socket on either side of the split. The opening through the lug 15 is adapted to be aligned with the bearing socket so that the leg of the bridge member passes through the lug when the bridge member is in position, and serves to lock the nasal end of the reinforcing band in position in the eyecup. The opening through the lug 16 at the temple end of the eyecup is adapted to receive a. connector for a head-band. Thus, the reinforcing band is secured to the eyecup at two points, the nasal end and the temple end, and holds thecushion firmly in place.

The legs l of the bridge member are split longitudinally to permit the legs to expand and contract transversely. At the upper end, they are provided with integral collars 19 which abut against the upper edges of the walls of the bearing sockets to limit the inward movement of the legs, and at one side of the lower end of each leg member there is formed a lateral projection 20 which forms 2O passes out of the bearing sockets, the leg expands and the shoulder 21 engages the lower edge. of the wall of the bearingsockets, locking the eyecup in the closed position.

The eyecup may be opened by contracting the" end of, and withdrawing the legmember. Thus the bridge member serves to lock the eyecups in the closed position.

It is obvious that various changes may be made in the details of the embodiment described above by those skilled in the art within the spirit and scope of my invention as expressed in the appended claims.
