3 Claims. (Cl. 214) This invention relates to safety goggles for protecting the eyes and adjacent area of the human face against the impact or entry of foreign particles such as are frequently encountered in industrial work. 7

An object of the invention is to provide a pair of safety goggles which will be light in weight, which can be worn over regular prescription spectacles, which can be easily adjusted for the differing facial contours to which the goggles are to be fitted and in which the lens member can be easily and readily replaced.

Another object of the invention is to provide a safety goggle in which the lens automatically adjusts itself within a limited range to the facial contour of the wearer. 1

Another object of the invention is to provide a pair of'light weight safety goggles which will furnish maximum protection to the eyes and adjacent face portions of the wearer but will, nevertheless, permit free circulation of air about the lens member to prevent fogging.

Another object of the invention is to provide safety goggles which can be slightly modified in form to permit the use of diiferenttypes of supports by which the goggles are supported upon the human head.

Another object of the invention is to provide safety goggles which are supported upon a frame which bears against the forehead and protects the eyes and adjacent face surfaces from any impact or shock if the goggles are struck by flying particles. 1

These and other features of the invention will be seen from the following detailed specification read in connection with the accompanying drawings forming part thereof and in which I Figure 1 is a side view of the 'pr'eferredform of safety goggles as worn over a pair of prescription glasses;

Fig. 2 is a topplan view of the preferred form shown in'Fig. l with the ends of the temples not shown; v 7

Fig. 3 is a perspective of the safety goggles shown in Figs. 1 and 2 with the temples folded into storage position;

Figs. 4., 5 and 6 show the lens adjusted in various positions upon the goggle frame;

Fig. '7 is a perspective of a modified form of the invention;

Fig. 8 is a plan view of the goggle frame of the form of the invention shown in Fig. 7 taken on the line 8-8 of Fig. '7;

Fig. 9 is a perspective of a second modified form Fig. 10 is a perspective of the frame of the modified form of the invention shown in Fig. 9.

Referring to the drawings, the frame for the safety goggles is indicated by the numeral l2. It is preferably formed of metal in the form of thin rods or strips which have some flexibility but can, nevertheless, be bent and formed as required. The frame consists of the crossbar l3 which is designed to bear against the forehead of the wearer and may, therefore, be covered with suitable covering material M such as a soft plastic tube or cushioning material of similar character. The cross bar terminates at each end in the positioning lugs [5.

Below the positioning lugs [5 are the frame uprights 16 each of which terminates in a lens support H. In the form shown in Figs. l-6 inclusive, hinges 18 are attached to the lens support I i as a pivotal mounting for the temples IS.

The lens member or shield, which is herein called the lens, is indicated by the numeral 20. It is formed from transparent, flexible material such as sheet plastic material of which many varieties are now available. Sheet materials of different thicknesses and color may be used according to the purpose for which the goggles are intended. The lens is formed as an integral elongated member of the form illustrated in Figs. 1, 2 and 3, that is of a slightly bowed or convex configuration cut away in the middle lower portion to provide a lens bridge 2! which is molded as shown in Figs. 3 and 4 to provide a rounded bearing portion where the lens rests upon the nose. The lens terminates at each end in a winglike side portion 22 bent substantially normal to the axis of the lens 29. These side portions are preferably cut with a plurality of positioning slots 23 and also the mountin slot 24, as best shown in Figs. 3, 4, 5 and 6.

The lens 20 is mounted upon the frame l2 by sliding the lens side portions 22 over the lens supports I! which will enter the mounting slots 24 and provide a suspension for the lens member. The positioning lugs [5 are inserted into one of the positioning slots 23. Which of the plurality of slots is selected depends upon the configuration of the face of the wearer and the most comfortable position of the lens upon the wearers face. The size and shape of the nose, the prominence and location of the cheek bones and the shape of the forehead are all factors which may slightly modify the ideal arrangement and relation of the lens 20 and frame I2.

The selective arrangement of the lens 20 upon the frame [2 available by the use of the plurality of positioning slots 23 is shown by Figs. 4, 5 and 6. The arrangement of this invention is so flexible that a frame portion which will fit the normal head will accommodate approximately ninety per cent of the wearers.

The use of the positioning slots 23 and mounting slots 24 gives the lens a freedom for vertical movement upon the positioning lugs l5 and lens supports I! which aids in the accommodationof the safety goggles to the difierent facial contours encountered. Thus, as is shown in Fig. 4, the lens may be lifted within the range of movement permitted by the positioning slot 23 and mounting slot 24, if the face of the wearer requires thataccommodation.

It is to be observed that the cross bar i3 is substantially at the upper edge of the lens 20 butv slightly spaced therefrom so that as the cross bar bears against the forehead the lens will be slightly removed from the front of the face leaving a passage for air between the safety goggles and the face to prevent the condensation of moisture thereon. This arrangement also insures that as the lens is struck with any flying material the shock or impact will be to a large extent absorbed by the lens member and such of it as is transmitted to the frame will be borne by the forehead and not by the areas of the face around the eyes.

The provision of this space between the eyes and the lens also enables the wearer to wear these safety goggles over the conventional types of prescription spectacles and thus the safety goggles provide protection for the underlying spectacles as well as for the eyes and face of the wearer.

The side portions 22 of the lens may be made in different forms and sizes depending upon the requirements for which the safety goggles are designed. In the preferred embodiment shown, the side portions are not extended very deeply,

and, therefore, are not designed to furnish any side protection for the eyes.

If the wearer is to be protected against material approaching the wearer from the sides, obviously side portions can be enlarged or modified in form to provide the most desirable protection.

A modified form of this invention is shown in Figs. '7 and 8 where the lens supports H are not provided with hinges but continue to form the shown in Figs. 9 and 10 where the frame 32 is simplified by the elimination of any temples whatsoever. In this form of the invention the safety goggles are supported upon the head of' the wearer by means of the headband 29, which is preferably made of elastic material and can be adjusted to the size of the head by means of the buckle 30. The headband is secured to the frame 32 by looping the ends of the headband about the frame uprights l6 where they are held against displacement by means of the lens supports [1.

In all forms of the invention the many objects hereinabove recited are achieved and the adjust- 4 ability of the lens to different facial contours is assured.

Another feature common to all forms of the invention is the ready interchangeability of lenses upon the lens frames. This permits not only the quick and ready replacement of lenses which may become damaged or scratched in use .-but-also permits the substitution of lenses of different weight'and color according to the purpose for which the safety goggles are being used.

Having thus shown and described several embodiments of the invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is intended to claim all novelty inherent in the invention as broadly as permissible, in view of the prior art.
