9 Claims.

This invention relates to light shields, more particularly to light shields used for excluding light rays from the eyes of the wearer.

In the designing of light shields it is not a simple task to provide a shield which will be effective in keeping all of the light rays from the eyes of the wearer. The chief reason for this is the difficulty of attaining a perfect fit between the shield and that portion of the wearers face which the shield is to cover, particularly the area at the intersection of the nose and cheeks. A generally satisfactory design may include an integral pad arrangement which serves to fill in such areas, however, due to the fact that some people differ greatly in head size and shape, it is not easy to make a standard size shield which will be satisfactory in every case. In such cases, the tight adjustment which may be necessary to hold the shield snugly against the face to provide maximum light restriction, can result in discomfort to the wearer after a prolonged period of use.

It is desirable that a light shield be easily maintainable in clean or sanitary condition. As a result of frequent use a light shield may become soiled with body perspiration and odor, and may serve as a carrier of germs from an afilicted wearer.

In the light shield of my invention I have provided a shield of simple design which overcomes the problems discussed above. Basically, "my shield comprises a combination including a body element and a pair of adjustable pad elements which can be positioned to eliminate passage of all light rays under the shield in the area of the wearers nose and checks, as will be readily apparent later. Furthermore, the shield of my invention can be easily maintained in sanitary condition, since it features attachable cover means which can be quickly affixed to the body of the shield, and removed for' cleaning pur-;- poses.

The main object of my invention is to provide a light shield which will effectively restrict passage of light rays from the eyes of the wearer.

A further object is to provide a lightshield which can be readily adjusted to give satisfactory service to any person regardless of head size and shape.

Another object is to provide a light shield'which can be easily maintained in clean or sanitary condition.

Other objects are to provide a light shield which is comfortable in use, simple in design, of low cost, and which will give long and satisfactory service.

These and further objects and features of the invention will become more apparent from a study of the following description and the illustrative drawings, in which:

Fig. 1 is a pictorial representation of the light shield of the invention in position on a wearer;

Fig. 2 is an elevation view of the basic shield of the invention as seen from the front or outside;

Fig. 3 is the same only as seen from the rear or face contact side;

Fig. 4 is a section as seen from line 44 in Fi 2;

Fig. 5 is a perspective view of one of the adjustable pad elements used in the shield;

Fig. 6 is an elevation view of the shield with a removabl cover in position and as seen from the front or outside;

Fig. 7 is a section view as seen from line 1-1 in Fig. 6;

Fig. 8 is an elevation view of the shield with another type of removable cover in position and as seen from the front or outside;

Fig. 9 is a section view as seen from line 9-9 in Fig. 8;

Fig. 10 is an elevation view of the shield with still another type of cover and as seen from the rear or face contact side; and

Fig. 11 is a fragmentary portion of a shield showing an alternate pad element arrangement.

Referring now to the drawings wherein like numerals have been used to indicate like elements in the several drawings, numeral 20 indicates a body or mask element formed in the shape illustrated and of such proportions as to cover the area of an average size face as shown in Fig. 1. The body element is preferably made from an opaque, stiff but flexible, sheet material such as the type known under the trade name Bakelite. A plurality of holes is formed in the body element to receive a holding cord 22, which is preferable of the covered elastic type used on light shields, and which is continuous in length as'shown. Two pairs of

holes

24, 25 are symmetrically arranged in the upper and outer extremity of the body element, the hole 24 being farthest from the vertical centerline of the shield. Another pair of holes 26 is located in the region of a nose cut-out region 28 of the body element. A final pair of holes 3!] is symmetrically arranged on on each side of the vertical centerline of the shield and at the lower edge of the body element, each of said holes 30 being located approximately midway between the pairs of

holes

24, 25 and 26, as shown. The cord 22 passes through the looped ends of a ribbon-like band 32, which has 3 a buckle 34 for adjusting the length thereof. A snap fastener 36 can be arranged on one loop of the band 32 if desired, to facilitat assembly of the shield.

In a preferred form of my invention, the cord 22 passes through a pair of pad elements 38 to maintain the latter on the backside of the mask 20, and in the area of the nose cutout 28, as shown. While the pad elements may be made. from any pliable and soft material, I have found that very satisfactory pad elements can be formed from a sponge rubber, such as the air foam rubber of the Goodyear Company. The pads 36 are adjustable in either direction along the cord so that when the shield is being worn, these pads may be suitably positioned to restrict passage of light rays underneath the shield for the particular wearer. At each end of the cord is attached a small metal bar 40 which fixes the cord to the shield.

The manner in which the cord 22 is arranged is to be observed. Notice that the cordpasses from the bar 56, through the hole 25, entersadjacent hole 2a to exit on the front side of. the shield, and enters the hole 36 from the frontv side of the shield. With this arrangement, the cord tends to press the mask in close contact with. the area of the wearer's face to be covered. If desired, the cord can be knotted just before entry from the front side of the shield into each hole 3-0, to regulate the tension of that portion of the cord upon which the pads 38 are maintained. In addition, small metal eyelets, (not shown) may be secured in each hole of the shield for reinforcement against wear and tear of the shield. While I have shown but one manner of affixing the cord to the shield, it willreadily occur tothose skilled in the art that other ways maybe as satisfactory, for example, the ends of the cord ma be permanently attached to the body portion 22 by any of theusual means.

While the description of the invention so far discloses a basic shield which may be satisfactory as such, the arrangements as illustrated in Figs. 6 toll are more nearly in-v accord with: all of'the objects of the invention.

In Figs. 6 and 7 the shield. of the invention is shown with a covering 42 which extends completely about the shield, i. e., both front and; rear, and which is open at both ends. The covering 42 is preferrably made from an opaque material, and may have a plastic insert or covering (not shown) on the inner side thereof. Suitable holes for the cord 22 may be made in the covering, which holes coincide with the holes in the shield. The number of holes to bemade in the covering can easily be determined from the illustrations of Figs. 6 and 7. It is to be noted that the covering 42 does not follow the contour of the mask at the nose cut-out portion 28', but rather encloses or extends over said portion. This ar rangement is of further help in the restriction of light rays from passage underneath the light shield. While the covering 4-2 is shown to be joined to itself along the top edge of the shield; other means, such as zipper attachments or snap fasteners, may be employed for such purpose with equal efiect. The cord 22 as applied to-v this em:- bodiment of the invention, is affixed. to the shield in the same manner as described in connection with the shield as illustrated in Figs. 2 to 4'.

Figs. 8 and 9 illustrate another arrangement of the. shield with a covering. In this embodiment the covering 42 extends only over the rear of the shield, so that it is positioned between; the

body member 20 and surface of the wearers face. In all other respects it is similar to the covering of the Figs. 6 and 7 illustration. While a simple method of attaching this covering to the shield, has been illustrated, it will readily occur that means such as snap fasteners may be used with equal eifect.

Fig. 10 illustrates another arrangement wherein the covering is greatly reduced in extent and comprises a pair of bag-like covers 64 which enclose the pad elements 38 in the region of action of the pad elements, as shown. The covers i t can be either affixed to the body element 20 by stitching as illustrated, or removably affixed by snap fastening means, or equivalent.

InFig. 11 isillustrated an arrangement where in the bag-like covers 44 of Fig. 10, contain pad elements:- 46 which are like the pad elements 38, except they are not apertured to receive a holdcord; In. this arrangement the pad elements 46- are maintained in adjusted position by virtue of snug contact with the inside of the covers l l. and, the pressure of the shield against the face of the wearer.

It will now be apparent that the light shield of my invention is. of simple design, will effectively restrict passage of light rays from the eyes of the wearer. is readily adjustable to give satisfactory service to any person so that a standard size is possible, and can. be easily maintained in sanitary condition.

While I have shown and. described the preferred manner of utilizing. the principles of my invention, it may occur to others that certain variations may be possible, thus I do not wish to be limited to the disclosure per se, but rather to the appended claims which clearly define the scope of the invention.
