Pressure equalizing mechanism for a diving mask










Image Number 6 for United States Patent #5572989.

An improved diving mask is disclosed. The diving mask includes a frame and a lens mounted and sealed within the frame. A flexible skirt is also mounted to the frame and designed to form a seal with a diver's face around the eyes and nose of the diver. The skirt includes a flexible nosepiece that fits over the nose of the diver. A stiff bracket is mounted to the frame and extends partially over the nosepiece. Additionally, an actuator is adjustably mounted to the bracket and cooperates with the nosepiece to selectively squeeze the nosepiece and restrict airflow through the nose of the diver.
