Abstract
An apparatus and method for use of an improved face shield assembly which prevents foreign materials or contaminants from vertically migrating from the above a wearer's head to the area around a wearer's face, eyes, nose and mouth.
Claims20
An improved halo brim comprising:
- a frame having a first arc, a cap having a second arc, and a bridge;
- wherein said frame and said cap are fixedly joined by said bridge, wherein said bridge is formed at a centerline bisecting said first arc and said second arc;
- said frame further comprising a lip that extends substantially around an outer edge of the frame;
- said cap further comprising one or more cap slots and one or more knobs;
- wherein each of said cap slots is for receiving and engaging a side edge of a face shield and wherein each of said knobs matingly engage with a hole formed on a surface of said face shield;
- wherein gaps around the bridge are reduced when the lip contacts the cap, creating a seal to prevent the downward mitigation of contaminants and/or particles from entering through substantially most of the gap by the frame flexing outwardly, when the improved halo brim is worn.

An improved face shield assembly comprising:
- an improved halo brim, and a face shield;
- said improved halo brim further comprising a frame, a cap, and a bridge, wherein said bridge fixedly joins said frame to said cap at a centerline, wherein said centerline bisects a first arc formed by said frame and a second arc formed by said cap;
- said frame further comprising a lip that extends substantially around an outer edge of the frame;
- said cap further comprising a plurality of cap slots and one or more knobs;
- said face shield comprises a first and second side edge;
- said face shield further comprises one or more detents or holes formed on a surface of said face shield;
- wherein said face shield is attached to the cap of the improved halo brim by inserting the first and second side edges of the face shield into the cap slots and matingly engaging the knobs of the cap with the detents or holes formed on the surface of the face shield;
- wherein said face shield is held by the cap at a distance away from a wearer's face;
- wherein gaps around the bridge are reduced when the lip contacts the cap, creating a seal to prevent the downward mitigation of contaminants and/or particles from entering through substantially most of the gap by the frame flexing outwardly, when the improved halo brim is worn.

A method of preventing contaminants and/or particulates from migrating vertically downward into the face of a wearer of a face shield assembly comprising:
- obtaining an improved halo brim comprising;
- a frame having a first arc, a cap having a second arc, and a bridge;
- wherein said frame and said cap are fixedly joined by said bridge, wherein said bridge is formed at a centerline bisecting said first arc and said second arc;
- said frame further comprising a lip that extends substantially around an outer edge of the frame;
- said cap further comprising one or more cap slots and one or more knobs;
- assembling the face shield assembly by attaching the face shield to the improved halo brim by inserting the side edges of the face shield into the to the one or more cap slots of the improved halo brim and inserting the one or more knobs of the cap into the detents or holes of the face shield;
- placing the face shield assembly on the head of a wearer, thereby outwardly flexing the frame of the improved halo brim such that the lip of the frame extends outwardly to engage an edge of the cap of the improved halo brim;
- and
- wherein gaps around the bridge are reduced when the lip contacts the cap, creating a seal to prevent the downward mitigation of contaminants and/or particles from entering through substantially most of the gap by the frame flexing outwardly, when the improved halo brim is worn.
