<p>A face shield (10) includes a crown (12), a head gear (14), and a lens (16) removably secured to the crown with a latch lever (62) having a wide paddle-shape that is easily manipulated from the rearward edge of the crown. The crown has an opposing pair of studs (38, 40) extending inwardly from the lower edge. The upper edge of the lens (52) includes an opposing pair of keyhole-shaped slots (54, 56) adjacent its opposing side edges which receive and rotatably engage the studs. The engagement end of the latch (62) includes a spaced pair of detents. The fulcrum (70) is secured to an inner surface of the crown so that the engagement end of the latch extends toward the front edge of the crown and the upper actuator end (66) extends toward the rearward edge of the crown. The upper edge of the lens includes a pair of spaced openings (84, 86) that releasably engage the detents (80, 82) on the latch lever.</p> |
