Definitions

  • the present invention relates to a protective faceshield and, more particularly, to a protective faceshield that has an opening for, and can be attached to, protective eyewear.
  • Johnson in U.S. Patent No. 4,821,340, discloses a faceshield to protect an individual against inhaling germs and other foreign bodies.
  • the Johnson faceshield includes a permanent clip portion which is adapted to be mounted on the nose piece of a pair of eyeglasses and a disposable sheet of relatively thin plastic which is removably attached to the clip thereby enabling the sheet to be removed and discarded after a single use and replaced by an identical sheet prior to treatment of a new patient.
  • the Johnson faceshield while providing an easy to use, low cost medical faceshield, does not shield all of the wearer's exposed skin surface as the device hangs from the nose piece of a pair of eyeglasses.
  • 5,206,956 discloses a one-piece protective faceshield including a generally flat semi-rigid transparent sheet, which may be bent into a semi-cylindrical face-covering shape and suspended from the bows of the frames of the eyeglasses of the user.
  • the Olson device includes a pair of integral bow-engaging clips adjacent to the top end edges of the transparent sheet. This device, while providing a simple and inexpensive disposable protective faceshield to cover the eyeglass frame and face of a user, also fails to shield exposed skin surface of the wearer. Dietrich, in U.S. Patent No. 4,944,039, and Parissenti et al., in U.S. Patent No. 4,843,643, also disclose a protective mask, or visor, attachable to eyeglass frames.
  • the Dietrich device includes a thin frame which is formed to cross transversely over the bridge of the nose, below the eyes and across the cheeks of a user.
  • a protective cover is attached to the thin frame and extends freely therefrom to hang in front of the nose and mouth of the user.
  • the Parissenti device protects dentists faces during oral surgery and includes a shield supported by bar elements connected to the rods, or temples, of a pair of spectacles or the like. These devices, however, also fail to cover all exposed skin surfaces of the wearer.
  • a further object of this invention is to provide a protective faceshield that covers substantially all of the wearer's exposed face when worn with eyeglasses, preferably safety eyeglasses. It is also, therefore, an object of this invention to provide a protective faceshield for use in numerous fields, particularly medical fields, to protect the wearer from fluid and particle spatters and any infection or injury therefrom.
  • the present invention provides a protective faceshield for attaching to a pair of eyeglasses.
  • the protective faceshield includes a face-covering sheet, extending from a forehead covering portion to a neck covering portion, having a cutout portion sized and shaped to expose a portion of the eyeglasses. The cutout portion is located over the effective viewing area of the wearer.
  • the faceshield also includes means for attaching the face-covering sheet to the eyeglasses.
  • the protective faceshield attachable to eyeglasses includes a face-covering sheet made of a transparent, semi-rigid thermoplastic film, selected from the group consisting of polyester, nylon, polycarbonate, polypropylene, polyethylene, polyethylene terephthalate, polyvinyl chloride, and the like.
  • the face-covering sheet has a cutout portion sized and shaped to expose a portion of the eyeglasses; preferably, safety eyeglasses are used with the protective faceshield of the present invention.
  • the face-covering sheet is attached to the brow or nosebridge portion of the eyeglasses.
  • the protective faceshield includes a face-covering sheet having a cutout portion, located over the effective viewing area of a -wearer, sized and shaped to expose a portion of the eyeglasses.
  • a connector for attaching the face-covering sheet to the eyeglasses is provided.
  • the connector typically has a substantially flat front portion and a flanged rear portion. The front portion extends over the face-covering sheet cutout portion, while the flanged portion extends around either a brow portion or a nosebridge portion of the eyeglasses to secure the faceshield.
  • the protective faceshield of the present invention generally can be applied to any pair of eyeglasses to provide the user with a lightweight, inexpensive faceshield which covers the face and protects the user from fluid and particle spatters.
  • the face-covering sheet is placed over the face and positioned until the cutout portion is located over the effective viewing area of the wearer, exposing a portion of the eyeglasses.
  • a means for attaching the face-covering sheet to the eyeglasses, preferably a flanged connector, is then inserted in a section of the cutout portion. The sheet is then secured to either the brow or nosebridge portion of the eyeglasses.
  • FIG. 1 is a front elevational view of one embodiment of a protective faceshield of the present invention, unattached to a pair of eyeglasses.
  • FIG. 1A is a front elevational view of an alternative embodiment of the protective faceshield of the present invention, unattached to a pair of eyeglasses.
  • FIG. 2 is a front elevational view of the protective faceshield as shown in FIG. 1, attached to a pair of eyeglasses.
  • FIG. 3A is a front elevational view of a connector used to attach the protective faceshield to the eyeglasses.
  • FIG. 3B is a cross-sectional side view of the connector shown in FIG. 3A.
  • the protective faceshield for attaching to a pair of eyeglasses of the present invention includes a face-covering sheet having a cutout portion sized and shaped to expose a portion of the eyeglasses.
  • the cutout portion is located over the effective viewing area of the wearer so as to minimize any distortion to the vision of a wearer.
  • the faceshield also includes means for attaching the face-covering sheet to the eyeglasses.
  • FIG. 1 shows a face-covering sheet 12 having a cutout portion 14 sized and shaped to expose a pair of eyeglasses (not shown) .
  • Cutout portion 14 provides an opening 15, located over the effective viewing area of a wearer.
  • sheet 12 includes a bubble-like protrusion, or non-perforated vent portion 16, which provides additional user comfort while allowing sheet 12 to be positioned closer to the face.
  • Protrusion 16 should also be able to accommodate the nose and any mask, for example, being worn by a doctor/surgeon.
  • protrusion 16 is elliptical in shape and tapers gracefully toward the nasal area of sheet 12.
  • Face-covering sheet 12 is typically made of a semi-rigid, thermoplastic film.
  • sheet 12 is made of a thin, lightweight, and transparent synthetic resinous plastic material, such as polyester, nylon, polycarbonate, polypropylene, polyethylene, polyethylene terephthalate, polyvinyl chloride, and the like.
  • sheet 12 is made of MYLAR® polyester film (trademark of E.I. DuPont de Nemours & Co., Wilmington, DE) due to its relative inexpensive cost and availability, as well as its advantageous physical properties. It is noted, however, that other materials known to those of skill in the art could be used to form sheet 12.
  • Sheet 12 can be formed by processes known to those skilled in the art, such as calendering, casting, thermoforming, or molding. Preferably, sheet 12 is thermoformed due to the relative inexpensive costs and ease of manufacture.
  • An anti-fogging agent, and/or anti-glare UV coating can be applied to the inner surface of sheet 12 to prevent the sheet from becoming clouded or otherwise potentially obstructing the wearer's view.
  • sheet 12 is substantially rectangular in shape, it is noted that a wide variety of shapes can be used. Sheet 12, however, must be sized to substantially conform to and cover the entire face of a user, preferably extending from a forehead portion 18 to a tapering neck portion 20; sheet 12 also extends, at side portions 22, beyond the eyeglass frames (not shown) it covers. Typically, a sheet 12 having an overall length between about 6 inches and about 16 inches and an overall width between about 6 inches and about 12 inches, has been found to be effective to cover the face, forehead and neck of a wearer. Preferably, sheet 12 has an overall length between about 8 inches and about 12 inches and an overall width between about 6 inches and about 9 inches. Lastly, sheet 12 should be of sufficient thickness to maintain its shape and rigidity. A thickness of between about 0.007 inches and about 0.030 inch for sheet 12 has been found suitable to maintain its shape without being obtrusive to any health care procedures being performed.
  • face-covering sheet 12' includes two cutout portions 14', sized and shaped to expose the lenses of a pair or eyeglasses (not shown) . Cutout portions 14' provide openings 15' which are located over the effective viewing area of a wearer. A third cutout 14' is provided over the nose bridge portion of a pair of eyeglasses. Cutout 14' provides opening 15' into which a connector (not shown) can be placed securing sheet 12' to the nosebridge portion of a pair of eyeglasses. Sheet 12' also includes a protrusion 16' to accommodate the wearer's nose and any facial mask being worn.
  • ridges 17 are provided below cutout portions 14' to provide additional splash protection for the wearer.
  • the ridges 17 can also provide a ledge beneath the eyeglasses' frames to prevent liquids or particles from entering opening 15' and falling between cutout 14' and the wearer's eyeglasses.
  • Face-covering sheet 12' can be made of similar materials, and be sized similarly, as sheet 12 described above.
  • face-covering sheet 12 is shown attached to a pair of eyeglasses 24.
  • the sheet includes cutout portion 14, as noted above, which is sized and shaped to expose a portion of eyeglasses 24.
  • the exposure of a portion of eyeglasses 24, over the effective viewing area of the wearer, helps to prevent the eyeglasses from fogging during use; in addition, the exposure of a portion of eyeglasses 24 prevents possible vision distortion which can be caused by a thick or soiled faceshield.
  • eyeglasses 24 include lenses 26, and frames 28; frames typically include rims 30, a brow portion 32, a nosebridge portion 34, and hinged temple portions 36.
  • Lenses 26 can be prescription lenses to correct sight defects, shaded lenses to protect the user from the environment, or safety lenses to protect a wearer's eyes in, for example, an industrial environment. Lenses may also be provided to address a combination of the above noted needs; for example, prescription sunglasses, prescription safety, or safety sunglasses.
  • lenses 26 are manufactured from a transparent material such as glass, or plastic materials such as polycarbonate and the like. It is preferred to attach the protective faceshield of the present invention to safety eyeglasses due to their ability to protect the wearer from, particularly, particle spatters. In safety eyeglass applications, polycarbonate is the preferred material due to its durability, and high impact strength.
  • Protective faceshield 10 also includes means for attaching face-covering sheet 12 to eyeglasses 24.
  • Sheet 12 can be attached to brow 32 or nosebridge portion 34 of eyeglasses 24.
  • Connector 38 is provided to attach sheet 12 and eyeglasses 24.
  • connector 38 is shaped to fit the particular opening of the frame for which it is made.
  • connector 38 has a substantially flat front portion 40 and a flanged rear portion 42.
  • Flange 43 forms rims 44 in rear portion 42 which secure sheet 12 to eyeglasses 24.
  • Connector 38 is typically made from the same material as sheet 12.
  • connector 38 can also be made of any semi-rigid material, preferably a synthetic resinous plastic material, such as polyester, nylon, polycarbonate, polypropylene, polyethylene, polyethylene terephthalate, polyvinyl chloride, and the like.
  • Connector 38 can be thermoformed in the same process as sheet 12, i.e., -as an integral, one-piece part of sheet 12, or it can be formed separately by other processes known to those skilled in the art.
  • Connector 38 is typically between about 0.5 inch and about 1.25 inches in length, and between about 1 inch and about 1.5 inches at its widest, and between about 0.5 inch and about 1 inch at its narrowest.
  • connector 38 is slightly oversized to fit snugly between cutout 14 while securing sheet 12 and eyeglasses 24.
  • cutout portion 14 of face-covering sheet 12 is located over the effective viewing area of a wearer.
  • Connector 38 attaches sheet 12 to eyeglasses 24 as front portion 40 extends over a small section of the periphery of cutout portion 14, while flanged rear portion 42 extends toward nosebridge portion 34.
  • the flange extends around the nosebridge portion 34 and snaps into position securing the nosebridge portion and the section of the periphery of cutout portion 14.
  • any type of snap, clip, hook, or fastening device can be used to attach face-covering sheet 12 to eyeglasses 24, provided the sheet is supported by either the brow 32 or nosebridge portion 34.
  • the wearer can use either prescription, shaded, safety, or combination eyeglasses.
  • the protective faceshield of the present invention is of a simple construction and is easily manufactured without providing the wearer with added bulk or visual distortion.
  • Various modifications may be desirable without departing from the scope of the invention.
  • additional side shields or non-perforated vents may be added to aid breathing and further reduce fogging.
  • a moisture-absorbing foam strip may be added to contact the forehead of a wearer to increase comfort while minimizing perspiration.
  • a resilient head-engaging band may also be added to the ends of forehead portion to provide additional support to the faceshield when in use.
  • Connector 38 may include a front handle or tab to aid the user in removing the faceshield.
  • a protective faceshield for attaching to a pair of eyeglasses having a shape and design substantially in accordance with the present invention is provided by the following combination of elements.
