33 JACK B. HIRSCHMANN M ATTORNE United States Patent 3,141,172 VENTILATED GOGGLES Jack B. Hirschmann, Fairhaven, Mass. The H. L. Bouton Co., Buzzards Bay, Mass.) Filed Sept. 18, 1961, Ser. No. 138,892 3 Claims. (Cl. 2-14) This invention relates to goggles and more particularly to ventilated goggles for protection against the exposure of the eyes to harmful and/or undesired liquids and the like.
The invention provides a versatile protective ventilated goggle which has ventilators arranged to resist the intrusion of liquids or other foreign matter accidentally sprayed, spilled, or otherwise impinged against the goggles. The ventilators in the goggles further provide for the removal by draining of any liquids which may have entered through the outer air openings as a further prevention of the entry of such foreign matter into the interior of the goggles.
It is therefore an object of this invention to provide a ventilated safety goggle especially constructed to protect the eyes and surrounding areas against the intrusion of foreign matter, particularly liquids, while at the same time also offering effective protection against flying chips and particles.
Another object of this invention is to provide safety goggles having ventilators wherein a cap which forms the ventilating opening has a blind side which is positionable toward the direction of expected intrusion.
A further object of this invention is to provide a ventilated safety goggle having a cap with at least one ventilating opening facing generally downwardly and forming a drain opening for the gravitational removal of any liquid which enters the cap.
A still further object of this invention is the provision of a safety goggle having ventilators with extending tube portions forming a circuitous path resisting the intrusion of liquids into the interior of the goggles.
Other objects and advantages of the invention will be apparent from the following description, the accompanying drawing and the appended claims.
In the drawing FIG. 1 is a perspective view of a ventilated goggle constructed in accordance with this invention;
FIG. 2 is an exploded view of the component parts of one of the ventilators in the goggle of FIG. 1;
FIG. 3 is a section through the cap of FIG. 2 taken generally along the line 33 of FIG. 2; and
FIG. 4 is a transverse section through one of the ventilators shown as being secured to the frame member of the goggles.
Referring to the drawing, which illustrates a preferred embodiment of this invention, a pair of ventilated safety goggles is shown as including a frame which may be constructed of relatively soft impervious plastic material such as disclosed in my Patent No. 2,773,260. The goggle frame 10 includes a rim portion 12 and a back portion or wall 14 which extends re-arwardly from the rim and terminates in a flange 15 for engaging the face of the wearer, and a nose pad 16 is molded integrally with the rim. A head strap 18 is shown as connected to the goggles by means of loops 19 provided near the back edge of the frame 10 at opposite sides of the goggles. The front rim portion 12 includes a lens 20 which is substantially complementary to the shape of the rim and which may be removably received therein in the manner disclosed in the above patent.
The goggle frame 10 preferably includes a plurality of ventilators positioned at opposite sides of the frame 10, with a pair of the ventilators 25 positioned at the top of the frame and another pair of the ventilators 25 positioned at the sides of the frame.
The ventilators 25 are preferably identical in construction, and reference may be had to FIGS. 2-4 for a detailed description of one thereof. Each ventilator 25 preferably includes a separate base member 26 which may be conveniently molded of plastic material, although other materials such as metal may be used. The base member 26 includes a tube portion 28 for insertion through a suitably prepared opening 29 formed in the frame It The tube portion 28 is adapted for insertion through the opening 29 with an end 30 extending outwardly from the frame. The base member 26 preferably further includes an integral annular flange 32 formed on the inside end of the tube portion 28 and arranged for sealing engagement with the adjacent inside surface of the wall 10. The base member therefore forms a ventilating opening 33 (FIG. 4) formed axially thereof.
The ventilator 25 also includes a generally cup-shaped cap 35 preferably formed from the same material as the base member 26 and having a cylindrical body portion 36. The cylindrical body portion 36 of the cap 35 is arranged to be assembled on the goggles in telescoping relation with the tube portion 28. The member 26 and the cap 35 may be secured together by means of threads 37 formed on the tube portion 28. However, it is within the scope of this invention to join these parts with a press fit or by a solvent seal, or any other convenient means of attachment. When so attached, the cylindrical body portion 36 of the cap 35 includes a terminal end 38 which forms an outer flange in sealing abutment with the adjacent outer surface of the Wall 10 in opposed relation to the inner flange 32.
The cap 35 further includes an integral closed outer portion or end 40, as shown in FIG. 4, which defines a ventilating space 41 between the end 40 and the outer end 30 of the tube portion 28. The cylindrical portion 36 of the cap 35 further includes means defining at least one, but preferably a plurality of, ventilating apertures 45 formed to lie inwardly of the end 30 and opening into the ventilating space 41. The apertures 45 extend radially through the cylindrical portion 36 at a location spaced between the outer end 30 of the tube portion 28 and the sidewall 10, thus providing a circuitous path leading from outside the goggles to the axial opening 33.
The cap 35 is preferably formed with the apertures 45 on one side only, thereby providing a blind side 46 which may be positioned toward the direction of expected intrusion of the foreign matter. Preferably, the ventilator 25 is arranged on the goggles 10 with the cap 35 angularly positionable or movable by the wearer to place the blind side 46 toward the direction of expected intrusion according to the particular use of the goggles. The arrangement of three apertures covering approximately 180 of the cap provides good ventilation and, at the same time, permits one of the apertures, designated as 45 in FIG. 4, to open downwardly for the drain-out of any liquid which may have accidentally entered the: ventilator.
In use, it is desirable that the wearer determine the direction in which the spray, flooding, or other intrusion is to be expected, and then to rotate the cap 35 to position the blind side 46 accordingly. It is preferable that consideration be given to the placement of an aperture 45 to face downwardly for the gravitational drain-out of any liquid which may accidentally enter the cap 35. It is therefore seen that air or foreign matter such as liquid or particles is caused to follow a circuitous path entering through the apertures 45 and/ or 45' and making a turn to arrive at the space 41 and then making a further turn of approximately to enter the interior of the goggles through the axial opening 33. This has the advantage of causing particles which are heavier than air .to impinge against the outer surface of the tube portion 28 and again against the inside surface of the end 40, thereby substantially decreasing the velocity of such foreign matter so that it may fall or drain downwardly through. the opening 45'. Also, the arrangement of the end 30 outwardly of the opening 45 and 45' operates in the manner of a stand-pipe or a breather pipe, particularly for the ventilators located adjacent the top of the goggles, thus further resisting the intrusion of liquid.
It is therefore seen that this invention provides versatile safety goggles with ventilators which give superior protection of the eyes against the intrusion of foreign matter. It is also recognized that these ventilators form eflicient lighttraps and are therefore ideally suited for use in combination with goggles wherein the light is intended to be excluded, such as welding goggles and the like.
While the form of apparatus herein described constitutes a preferred embodiment of the invention, it is understood that the invention is not limited to this precise form of apparatus. As an example, the tubular portion 30 may be formed or otherwise suitably carried on the cap 35 and proportioned to extend into the opening 29. Also, the flange 32 may be formed as a separate piece which is solvent soldered to the portion 30 at the frame 10 after assembly. Thus, it is seen that these and other changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
