LIGHTWEIGHT FACE SHIELD
A face shield including a flexible transparent sheet and a strap component having a strap configured to encircle a wearer's neck, with a pair of support arms disposed on the strap which are secured to a lower portion of the sheet at two spaced apart locations. The support arms extend away from the strap so as to support the sheet in front of, and spaced apart from, the wearer's face. The extended support arms further introduce a bend in the sheet to provide lateral facial coverage.
The present invention relates generally to face shields and in particular to low cost, lightweight face shields that can be shipped in a compact form and then easily assembled for use by the end user.
2. Description of Related ArtVarious types of face shields are employed to protect all, or part of, the wearer's face from hazards such as flying objects, chemical splashes or potentially infectious materials. Such shields can also be useful in discouraging the wearer for touching his/her face. Face shields intended for infection control, sometimes referred to as medical face shields, are usually constructed from relatively lightweight materials as compared to shields intended to provide protection from flying objects such as wood chips, roadside debris and the like. Medical face shields have a tendency to be somewhat awkward to wear over extended periods of time, particularly those devices intended for use in healthcare settings such as hospitals.
There is a need for a very lightweight and low cost face shield, particularly for non-healthcare settings. Such a face shield needs to provide adequate room to accommodate eye glasses, face masks and other items frequently worn concurrently with the face shield. As will become apparent to those skilled in the art upon a reading of the following Detailed Description of the Invention together with the drawings, the present invention addresses these needs and requirements unlike conventional face shields.
SUMMARY OF THE INVENTIONA face shield is disclosed which includes a flexible transparent sheet supported over the user's face by a strap component, with the strap component having an elongated strap configured to be worn around the user's neck. The strap component further includes a pair of support arms secured at spaced apart locations on the elongated strap. Each support arm includes an attaching section and an arm section, with the arm section being separated from the attaching section by an intermediate transition region. The support arms are secured to the elongated strap exclusively by way of the respective attaching sections and are positioned on the strap facing one another so that the transition regions are spaced apart from one another a distance of at least one half a width of the transparent sheet.
Fasteners are positioned to secure the first and second arm sections to spaced apart locations on the transparent sheet. When the elongated strap is formed around the user's neck, the arm sections extend away from the curved strap at the respective transition regions and spread apart from one another. This action allows the support arms to position and secure the transparent sheet in front of the user's face and further introduces a bend in the transparent sheet so that the sheet wraps around the user's face to provide lateral coverage. The geometry of the support arms is such that the bent sheet is spaced apart from the user's face a sufficient distance to accommodate eye glasses and other items worn concurrently with the shield. In addition, the support arms are disposed at an angle with respect to the elongated strap so that the sheet is positioned vertically in front of the face. Typically, the fasteners are implemented using hook and loop mechanisms so that the flexible sheet can be readily separated from the strap component for ease in cleaning, shipping and storing.
Referring again to the drawings,
The shield component 20 further includes pair of the fasteners for securing the transparent sheet 22 to the strap component 20. A segment 24A of one half a hook and loop fastener, sometimes referred to herein as a fastener half, is secured by adhesive to the sheet at the corner formed by edges 22A/22C. Another fastener half 24B is secured by adhesive to the sheet at the corner formed be edges 226/22C. The active side of the fastener halves 24A and 24B are both facing the observer of
As previously noted, the shield component 20 is supported over the user's face by the strap component 26. In particular, the transparent sheet 22 of the shield component is supported exclusively on the user by a pair of support arms 28/30, as will be described.
In addition to securing the transparent sheet 22 on the user, the strap component 26 is configured to introduce a bend in the otherwise planar transparent sheet 22 so that the sheet provides lateral coverage of the user's face as depicted, by way of example, in
The strap component 26 is shown in
A pair of identically shaped, spaced apart support arms 28 and 30 are supported in the central region of the elongated strap 36. The support arms 28/30 can be fabricated having a cardboard substrate which is covered by the same two plastic outer layers used on the elongated strap 36.
The two arm sections 28B/30B of the respective support arms 28/30 are attached to the elongated strap 36, utilizing an adhesive, exclusively by way of the respective attaching sections 28B/30B. The surfaces of the arm sections facing away from the observer of
The arm sections 28B/30B extend away from the respective narrow transition regions 28C/30C toward one another when the strap component 28 is in the planar form shown in
The above-described alignment steps insure that transparent sheet 22 is disposed at a desired fixed angle A (
As can perhaps best be seen in
There should be sufficient space between the curved sheet 22 and the user's face to readily accommodate eyeglasses, surgical face masks and the like which may be concurrently worn by the user. This spacing is dependent, in large part, upon the distance that the support arms 28/30 extend away from the looped elongated strap 36 (
The face shield embodiment just disclosed allows the configuration of the shield to be altered by varying, within limits, the values of dimensions W, D, L and C (
Thus, a lightweight and low cost face shield has been disclosed. The shield relies solely on the neck mounted strap component for support rather than, for example support from ear loops and the like. Thus, eyeglasses and face masks of the type which utilize the ears for support can be easily accommodated. Although a single embodiment of the face shield has been disclosed, it is understood that various changes can be made by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
