2 Claims. (Cl. 2-14) This invention relates to improvements in goggles of the so-called cover-all type used principally for eye protection against flying particles resulting from industrial operations and the like.
it is an object of this invention to provide novel goggles which are sturdy and shock resistant, are easily maintained in good useable condition and are economical to manufacture.
It is a further object to provide such a device which will afford good protection against flying particles and splash while still having efiective ventilation for the interior thereof.
Further objects and advantages reside in the novel details of construction, and the arrangement and combination of parts which are described in the specification herebelow and are shown in the accompanying drawing in which:
Fig. 1 is a front view, partly cut away and shown in section, of a preferred form of this invention,
Fig. 2 is a fragmentary rear view of the goggles, partly broken away and shown in section,
Fig. 3 is a fragmentary sectional view taken on the line 3-3 of Fig. 1, and
Fig. 4 is a fragmentary sectional view taken on the line 4-4 of Fig. 2.
Goggles constructed according to this invention, shown generally at it) in Fig. l of the drawing, comprise two principal parts, namely, an integral frame or body 11 and a demountable lens means or panel 12. Both parts 11 and 12 are preferably formed from a molded plastic material such as polystyrene, vinyl acetate, or the like, and the lens panel is necessary transparent. The structure of frame 11 comprises an upright front wall 13 which is curved from side to side and is provided with a pair of sight openings 14 and 15. Extending rearwardly from the front wall 13 is a top wall 16 and side Walls 17 and 18 which are continuously and integrally formed so as to extend from the upper side around the lower side of the front wall to a protruding nasal portion 19 that is adapted to accommodate the wearers nose. Covering substantially the entire front wall 13 is the aforesaid lens panel 12 which is normally flat but is held upon assembly in a stressed and curved position by means hereafter described.
An important feature of this invention is the substantially continuous rib 21 formed integrally on the marginal portions or" the front wall 13 so as to project forwardly thereof and cover the edge of the lens panel 12. This rib 21 effectively covers the clearance space 22 between the front Wall 13 and lens panel 12 so that no flying particles, such as grinding products, etc., may enter the interior of the goggles. On the temporal sides of the "ice goggles, overhanging flanges 23 and 24 are formed integrally with the rib 21 and these flanges project inwardly so as to provide in cooperation with the rib and the front wall a pair of seating grooves 25 and 26 in which the end portions of the lens panel 12 may engage.
The ventilation means constitutes another feature of this invention and it is provided by forming several offset portions 27, 28, 29 and 30 on the temporal and side parts of the goggles 10, the forward faces of said portions being set back from the plane of the lens panel 12. In said forward faces are formed numerous small ventilating apertures 31 which lead air rearwardly into the interior of the goggles. For the purpose of diverting the incoming air from the wearers eyes, rearwardly projecting bafl'le plates or walls 32, 33, 34 and 35 are formed on the rear of the front wall 13 around the inner side of the apertured areas.
Anchorage recesses 36 and 37 having openings 38 and 39, respectively, through the side Walls of the goggles are provided in which a head strap, not shown, may be secured.
In assembling the lens panel 12, one end of it is engaged in one of the seating grooves 25 or 26 and the panel is flexed until the other end thereof may be placed in the other groove. The natural stiffness of the panel 12 should be sufficient to hold it in extended position in engagement with both of the seating grooves 25 and 26.
Although only a preferred embodiment of this invention has been shown and described in detail, it will be understood that other embodiments are possible and changes may be made in the form and arrangement of the parts thereof and substitutions may be made therein without departing from the spirit of the invention as defined in the claims herebelow appended.
1. A goggle comprising an integral body having a front wall carrying lens means, a top wall and side walls extending rearwardly from the front Wall, said side and top walls having offset portions located rearwardly of the plane of the lens means, said portions having forwardly facing apertured walls to provide ventilation, and baffle plates formed integrally with the body and extending rearwardly from the inner edge of the apertured walls whereby currents of air entering the apertured Walls will be directed rearwardly of the eyes of the wearer.
2. In a goggle the combination of an integral body comprising a front wall having a pair of spaced sight openings, a one-piece lens panel removably secured over the sight openings in eye protecting relation and means for securing the lens panel to the body member comprising a rib projecting forwardly of the plane of the lens panel and extending continuously around the body member, and inwardly projecting overhanging portions formed on the rib along only the temporal sides of the body to form in cooperation with the front wall lens receiving grooves, the edges of said lens panel abutting said rib and the temporal ends of the lens panel being received within said grooves whereby the forwardly projecting rib prevents flying particles from entering the goggle between the lens panel and the front wall.
