The present invention is directed to a face shield device that provides protection against virus-containing aerosolized particles when cloth, surgical masks, or full-face shields are impractical to use. In particular, the present invention is directed to a handheld demi-face shield device.
The following description is not an admission that any of the information provided herein is prior art or relevant to the present invention, or that any publication specifically or implicitly referenced is prior art. Any publications cited in this description are incorporated by reference herein. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.
During the COVID-19 pandemic, the Centers for Disease Control and Prevention (CDC) issued guidance relating to customers at restaurants, recommending masks be worn by employees and customers as much as possible when not eating or drinking and when social distancing measures are difficult to maintain. Generally, employees keep a mask on at all times, whereas customers unmask once the food and drinks arrive, or “when not actively eating or drinking”. Ultimately, this places the employees who interact with unmasked individuals, as well as other close-by restaurant guests and passers-by, at a greater risk of exposure to the virus. Oftentimes, it can take several seconds for a person to resecure his or her mask and may be impractical by the time a person approaches the table. In another scenario, the customer grabs the mask by the center and holds it in place over his or her nose and mouth with his or her hand. This option is unhygienic and may still result in placing the other person at risk of exposure to the virus. Lastly, speech may be muffled while the customer is wearing his or her mask making it difficult for the others to hear. Sound is further muffled when the table is outside and the voice is competing with the restaurant's music, other conversations close by, and traffic.
For the forgoing reasons, and for other scenarios where a mask is impractical, a need exists for a device that is easy to use, and can be rapidly and easily attached and removed from a user's face.
The present invention relates to a demi-face shield device that provides a user the ability to hold the mask in front of the face for source-control protection of other persons from particles from the mouth and nose. Furthermore, the device provides self-protection from inhaling particles in an environment where maintaining a safe distance is difficult or undesirable. The present invention is a curved demi-shield frame piece secured by a slidable clip which is in turn snapped onto a dowel adapter. The device contains a plurality of dowel holes configured to connect to the dowel handle in multiple positions to accommodate the user's preference. A fuller size face shield version is configured to extend to provide eye coverage for additional protection against ocular contamination.
In an embodiment, a handheld demi-face shield device comprises a demi-shield comprising an outer edge, a first end, a left edge, a right edge, a second end, a bottom portion, and a top portion; a nose bridge; a dowel adapter; and a dowel handle. In one embodiment, the nose bridge is removably affixed to demi-shield; and in another embodiment, the dowel adapter comprises a slideable clip, a receiving portion, a face, plurality of dowel holes, and a dowel cuff. In one embodiment, the first end is optionally tapered. In another embodiment, the second end is optionally tapered. In yet another embodiment, the first end and the second end are optionally tapered.
In yet another embodiment, the plurality of dowel holes are configured to allow a user to adjust the height of the demi-shield and the angle of the dowel handle to the demi-shield.
In a further embodiment, the face is in the shape of a half-sphere wherein the slideable clip is permanently affixed to a flat side of the face.
In yet another embodiment, the dowel cuff comprises a hollow end and a protruding end wherein the hollow end is capable of receiving the dowel handle and the protruding end is inserted into one of the plurality of dowel holes.
In one exemplary embodiment, the dowel adapter is removably attached to the left edge of the demi-shield using the slideable clip.
The dowel adapter is removably attached to the right edge of the demi-shield using the slideable clip.
In yet another embodiment, the plurality of dowel holes are configured to accommodate varying diameter of the protruding end.
In still another embodiment, the slidable clip is configured to engage varying thicknesses of the demi-shield.
