Description

Australian Patents Act 1990 - Regulation 3.2 ORIGINAL COMPLETE SPECIFICATION STANDARD PATENT Invention Title Sun shields for ears The following statement is a full description of this invention, including the best method of performing it known to me/us: 5102 HA11:I\111CAVOVCNNY0tD1WUUUVI L1A\313545_l.d0C-9/07/2014 - 1 SUN SHIELDS FOR EARS Field of Invention 5 The present invention relates to a combination of a pair of sunglasses and at least one ear shield. For example, the present invention relates generally to safety devices for protecting ears from the harmful ultraviolet rays of the Sun, and in a particular though non-limiting embodiment to sun shields that can be used with glasses or headgear to provide an improved ear protector, and an associated method for shading and protecting ears from the 10 Sun. Background of Invention With various surveys indicating that fewer than 33% of people routinely use sunscreen or 15 sun protection, skin cancer has become a dangerous risk and unfortunate reality for many people. However, the public is becoming increasingly more aware that consistent use of broad-spectrum sunscreens and sun-protective practices can help prevent skin cancer. One area particularly vulnerable to the Sun's harmful rays is the ears. Recent studies have 20 shown that the ears are the third most frequent location for basal cell carcinomas, with approximately 39% located on the front of the ear; approximately 37% located on the back of ear; and approximately 24% on the rim of the ear. Numerous devices are available for protecting different parts of the head from the Sun's 25 harmful ultraviolet rays, especially for protecting the face and eyes via different types of headgear and sunglasses or eyeglasses. However, there are no commercially viable options for providing protection to the ears. All known, related prior art patents suffer from some sort of limitation. In particular, most 30 do not address safety issues associated with blocking the ear and interfering with hearing; none provide a high degree of flexibility with respect to fit and adjustability for the user; and many are too complex to be commercially and economically viable.

For example, U.S. Pat. Nos. 4,751,746 to Rustin (1988) and 5,943,703 to Avila (1999) describe ear protectors that cover the ears and appear to significantly block the ear opening, which could interfere with hearing and potentially create a safety issue if used in a work environment such as construction. Similarly, U.S. Pat. No. 5,619,750 describes an immovable ear shield having three surfaces, which would not easily admit to comfortable wear; and U.S. Pat. No. 6,550,064 discloses an ear shield apparatus limited to use on headgear. While previously known commercial embodiments are available for shielding ears, these too suffer from one or more of the following disadvantages: (a) The designs are too complex to be commercially and economically viable. For example, many have complex shapes and numerous parts that must be manufactured and assembled. Complex features, unusual shapes, or multiple parts increase the difficulty and cost of manufacture, thereby causing the resulting ear shield to be cost prohibitive or less economically attractive to a potential purchaser. (b) Some ear shields can block the ear and interfere with hearing, thereby leading to safety concerns if used under conditions in which unimpaired hearing is essential. (c) The fit and adjustability of existing ear shields are limited, thereby often providing little or no flexibility, thus limiting the usefulness and comfort of the product for the user. (d) Known shields presently in use can be difficult and time-consuming to attach or use as required for adequate protection from harmful ultraviolet rays. (e) Known shields are generally not available in multiple sizes and/or are too small to 2 r1;\IU\ItCTOV~i~lNE~ft I\ 3I J Dtli\3343_ I,00C-WU L4| -3 provide adequate shade. The lack of availability of different sizes for men, women and children, or having a single, uniform size that is too small may result in the ear shield not providing enough shade for adequate protection or may make the ear shield uncomfortable, unattractive, or undesirable to wear. 5 (f) An important consideration in the use of ear shields is that they be durable enough to withstand use during physical activities such as sports, construction and other outside endeavors. A lack of durability is also a consideration in known designs that limit the usefulness of ear shields. 10 It is generally desirable to overcome or ameliorate one or more of the above described difficulties, or to at least provide a useful alternative. Summary of Invention 15 According to the present invention, there is provided a combination of a pair of eyeglasses and at least one ear shield, said eyeglasses comprising a frame and pair of temple sections, said at least one ear shield comprising: (a) a main body having an upper surface, a lower surface on the opposite side of said upper surface, an inner edge, an outer edge, a forward section, and a rearward 20 section, said inner edge and said outer edge extending from said forward section to said rearward section; (b) at least one of at least one hole cut through said shield and located proximal to said inner edge and an attachment area along said inner edge; and (c) said forward section of said ear shield being of sufficient size to extend over 25 the ear of the wearer.

Still further objects and advantages will become apparent to those of skill in the art from consideration of the following detailed description of several example embodiments, 20 especially as read in conjunction with the related drawings and parts list summarized above. As seen in the example embodiments depicted in FIGs 1-2, a sun shield for ears comprises a flat body of a flexible material having an upper surface; a lower surface; an outer edge; and an inner edge with means for attaching to the temple portion of a pair of eyeglasses. The sun shield is attached to the temple part of the glasses such that the inner edge of the body is positioned along the temple part of the glasses, and the sun shield extends horizontally over an ear, whereby the ear shield is positioned over the ear and therefore shaded from the harm ful rays of the Sun. The ear shield 10 can be made of a variety of materials, e.g., foam, cloth, plastic, elastomer, UV-A and UV-B opaque material, fiberglass, rubber, metal, and various other materials providing IV protection. An especially useful material is a flexible material, for example, a cross-linked foam formed into a sufficient size and shape as to block the Sun's rays and provide shade for the ears. In one embodiment, the ear shield 10 has a flat body with an upper surface 20; a lower surface 22 located on the back side of the upper surface 20; a forward section 26; a rearward section 28; an inner edge 12 and an outer edge 14 that extend from the forward section 26 toward the rearward section 28; and a plurality of holes 18 disposed proximal to and along to the inner edge 14. In one embodiment, a plurality of holes 18 are spaced proximal and parallel to the inner edge 12. In an alternative embodiment the shield 10 has two holes 18, with a first hole 18 located in the forward section 26 and a second hole 18 located in the rearward section 28. In a further embodiment, the ear shield 10 is sized such that the forward section 26 will provide adequate shade to an ear when the ear shield 10 is placed directly over the ears of a 8 human being, with the inner edge 12 parallel to and touching the circumference of the head. In a still further embodiment, the ear shield 10 is removably attached to eyeglasses 30 by inserting the eyeglass 30 temple bar 34 through the hole 18 disposed on upper surface 20 of the forward section 26, and then again through the hole 18 on the lower surface 22 of the rearward section 28 as shown in FIG. 2. As seen in the example embodiments depicted in FIGs. 3-6, the ear shield 10 further comprises an attachment strip 25, which is attached to and runs along the inner edge 12 from the forward section 26 toward the rearward section 28; a pivot flap 19 that extends across the forward section 26 from the inner edge 12 toward the outer edge 14; and a molded wire 15 inserted into the ear shield 10 material and running along the outer edge 14. In further embodiments, the attachment strip 25 provides an attachment means for attaching the shield 10 to the temple bar 34 of eyeglasses frame 32, and/or the pivot flap 19 provides means for adjusting the ear shield 10 in order to assist personalized user adjustment of the shield for better fit and comfort. In a still further embodiment, the molded wire 15 provides support for the ear shield 10, and serves as an additional means for allowing the user to bend, shape, and adjust the ear shield 10 to meet personal preference for fit and comfort in shading the ears. As seen in the example embodiment depicted in FIG, 7, the ear shield 10 further comprises an attachment area 24 that can be combined with an attachment means to attach to eyeglasses or headgear (e.g., hats, visors, helmets, etc.) in order to provide better shade for the ears of a user. 9 As seen in the example embodiment depicted in FIG. 8, the ear shield 10 is attached to eyeglasses 30 and has an edge material 16 that runs substantially along the perimeter of the shield 10 including the inner edge 12 and outer edge 14. In one embodiment, the edge material 16 is a flexible and durable wire embedded in the shield 10 material, provides additional support for durability, and allows the wearer to adjust the ear shade to meet personal preference for fit and comfort by bending and adjusting the edge material 16 as desired to the preferred shape and angle. In another embodiment, the ear shield 10 is attached to the eyeglasses temple bar 30 via glue, sewing, clamp, clip, or another attachment means. In still another embodiment, the ear shield has one or more sleeves or holes that allow it to be removably attached to the eyeglasses temple bar 34 by sliding the temple bar 34 into the sleeve or sleeves, or sliding the temple bar 34 into a hole or holes that allow the temple bar to pass through and hold the shade, the preferred location of sleeve or hole being along the inner edge. In yet another embodiment, the ear shield is attached to headgear (e.g., cap, visor, etc.), by attaching the ear shield 10 inner edge 12 to the headgear in a location proximate with the wearer's ears. The ear shield 10 may be permanently attached to the headgear via glue, clamp, clip, sewing, fuse, snaps, plastic injection, wire, or another attachment means; or removably attached to headgear via clamp, clip, sleeve, hole, hook and loop fastener, snap, or another attachment means, thereby providing removable attachment.
