Face Shield

Abstract

A face shield made of a single sheet of transparent material. An example face shield includes a front face covering, a first side strap having a tab, and a second side strap having at least one slot. The slot is configured to engage with the tab on the first side strap to assemble the first side strap to the second side strap and form a band for positioning the face shield on a user's head. A cantilever tab is provided above the front face covering, and a slot is formed in the front face covering. The cantilever tab rolls back onto the front face covering and the cantilever tab connects into the slot to form an adjustable spacer to maintain a distance between the user's head and the front face covering when worn by the user.

1 . A face shield comprising:
 a single sheet of transparent material;   a front face covering formed of the single sheet of transparent material;   a first side strap formed of the single sheet of transparent material, the first side strap having a tab formed therein; and   a second side strap formed of the single sheet of transparent material, the second side strap having a slot formed therein, the slot configured to engage with the tab on the first side strap to assemble the first side strap to the second side strap and form a band for positioning the face shield on a user's head.   
     
     
         2 . The face shield of  claim 1 , further comprising a cantilever tab above the front face covering and formed of the single sheet of transparent material. 
     
     
         3 . The face shield of  claim 2 , further comprising a slot formed in the front face covering, wherein the cantilever tab rolls back onto the front face covering and the cantilever tab connects into the slot formed in the front face covering to form an adjustable spacer to maintain a distance between the user's head and the front face covering when worn by the user. 
     
     
         4 . The face shield of  claim 3 , wherein the cantilever tab is configured to provide a spring-loaded force that presses against the user's forehead when the band is positioned on the user's head. 
     
     
         5 . The face shield of  claim 3 , wherein the cantilever tab is adjustable to provide different effective stiffnesses of the adjustable spacer. 
     
     
         6 . The face shield of  claim 3 , wherein the cantilever tab is adjustable to provide different spacings between the user's head and the front face covering. 
     
     
         7 . The face shield of  claim 3 , wherein the cantilever tab provides different effective stiffnesses based on at least one of a width of the cantilever tab, a length of the cantilever tab, a shape of the cantilever tab, a radius of the cantilever tab, a thickness of the cantilever tab, and a material of manufacture of the cantilever tab. 
     
     
         8 . The face shield of  claim 1 , wherein the adjustable spacer reduces curvature and ocular distortion in front of the user's face. 
     
     
         9 . The face shield of  claim 1 , wherein the adjustable spacer provides an adjustable amount of ventilation to reduce build-up of heat and perspiration on the wearer's face and forehead. 
     
     
         10 . The face shield of  claim 1 , wherein the single sheet of transparent material is pre-cut. 
     
     
         11 . The face shield of  claim 1 , wherein the single sheet of transparent material is at least partially pre-cut. 
     
     
         12 . The face shield of  claim 1 , wherein the single sheet of transparent material is at least partially perforated and features are formed by removing perforations. 
     
     
         13 . The face shield of  claim 1 , further comprising a plurality of slots formed in the front face covering for changing one or more property of the adjustable spacer. 
     
     
         14 . The face shield of  claim 1 , further comprising a plurality of slots formed in the second side strap to engage with the tab on the first side strap to assemble the first side strap to the second side strap and form a size adjustable band. 
     
     
         15 . The face shield of  claim 1 , further comprising an anti-fog coating on the front face covering. 
     
     
         16 . The face shield of  claim 1 , further comprising an anti-glare coating on the front face covering. 
     
     
         17 . The face shield of  claim 1 , further comprising an anti-UV light coating on the front face covering. 
     
     
         18 . The face shield of  claim 1 , wherein the single sheet of transparent material is recyclable and/or biodegradable. 
     
     
         19 . The face shield of  claim 1 , wherein the single sheet of transparent material can be cut and shaped to customize fit or size of the front face covering. 
     
     
         20 . A face shield comprising:
 a single sheet of transparent material;   a front face covering formed of the single sheet of transparent material;   a first side strap formed of the single sheet of transparent material, the first side strap having a tab formed therein;   a second side strap formed of the single sheet of transparent material, the second side strap having a plurality of slots formed therein, the plurality of slots configured to engage with the tab on the first side strap to assemble the first side strap to the second side strap and form a band for positioning the face shield on a user's head;   a cantilever tab above the front face covering and formed of the single sheet of transparent material,   a slot formed in the front face covering, wherein the cantilever tab rolls back onto the front face covering and the cantilever tab connects into the slot formed in the front face covering to form an adjustable spacer to maintain a distance between the user's head and the front face covering when worn by the user.
