referring to the drawings , goggle 10 comprises front 12 molded or otherwise formed of a polycarbonate or similarly suitable material and temples 14 molded or otherwise formed of nylon , i . e . the somewhat different materials avoid squeeking noises during pivoting of the temples . otherwise , the front 10 and temples can be formed of like materials . front 12 , of one piece construction , includes right and left forward viewing lens areas 16 , 18 with a nasal recess 20 therebetween , wrap - around endpieces 22 and a rearwardly directed brow portion 24 . nasal recess 20 supports nosepiece 26 formed of a molded soft material such as silicon rubber or an equivalent . nosepiece 26 is dovetailed into recess 28 of front 12 ( fig6 ) with depending ends 30 attached in bayonet slots 32 . circular openings may be substituted for slots 32 . a tab 33 extending rearwardly from nosepiece 26 adjacent each of its ends 30 ( fig7 ) is hooked into a respective slot 32 or pulled through a correspondingly positioned circular opening if circular openings are used . material of front 12 extending about the portion of nasal recess 20 which receives nosepiece 26 is thinned as shown in fig6 and 7 for intimate nosepiece fitting and improved goggle aesthetics . this thinning of the goggle front may , however , be dispensed with and a nosepiece molded thereinplace as an integral part of front 12 as a substitute for nosepiece 26 , if desired . brow portion 24 of front 12 extends rearwardly of lens areas 16 , 18 to upturned lip 34 which is intended for engagement with a wearer &# 39 ; s forehead . centrally of lip 34 is a forwardly directed relief 36 which provides a ventilation opening between the head and front 12 , i . e . the space between broken line 38 and relief 36 permits ventilation of the spaces between lens areas 16 , 18 and a wearer &# 39 ; s face for avoidance of goggle front fogging as will become more readily apparent from the following . functioning with relief 36 of brow portion 24 are air scoops 40 ( fig2 and 5 ) in temples 14 which afford vertically elongated air entrance openings 42 , one of which is shown in fig2 and 3 . with each opening 42 extending approximately from top to bottom of scoop 40 , e . g . over a length of approximately 13 / 4 inches in each case , optimum goggle front ventilation is accomplished without sacrifice of flying particle protection . in this connection , the width of opening 42 is preferably held to a dimension x ( fig3 ) of approximately 0 . 040 inch . with goggle 10 applied to the face , air between the face and lens areas of front 12 , warmed by the wearer , rises outwardly through the opening provided by relief 36 allowing cooler outside air to enter through scoops 40 and travel across lens areas 16 , 18 as indicated by arrows 44 ( fig1 ). this prevents lens fogging particularly in the heretofore troublesome nasal areas . in addition to air scoops 40 , temples 14 feature upper and lower turned - in edges 46 , 48 which provide for close fitting against the head and protection against entrance of external foreign matter into temporal regions of the goggle . additionally , and in a unique and simple fashion , pivot pins integral with the temple construction in each case are adapted to snap - fit into corresponding openings in the endpieces 22 of front 12 for hinging the temples thereto . it should be understood , however , that other forms of temple hinging may be used if desired . the foregoing is believed to illustrate the improvements in facial fitting and general aesthetics afforded by the present goggle 10 and more particularly its highly significant anti - fogging design features . it should be understood , however , that various modifications and adaptations of the precise form of the invention described above may be made to suit particular requirements and it is intended that all modifications which incorporate the novel concept disclosed are to be construed as coming within the scope of the following claims or range of equivalency to which they are entitled .
a safety goggle including a one - piece wrap - around front with hinged temples continuing rearwardly therefrom . the goggle features improved anti - fogging ventilation and universal nasal area face fitting .
