US Patent 7134148 Swim mask

A compact, waterproof swim mask having a unitary skirt, a frame, and a clinging device. The unitary skirt has two lenses for covering the eyes and/or the nose of a user, a flexible frame including two eye-shaped frame elements being capable of communicating with each other. Each frame element is bendable to slightly enlarge when an upper portion is pulled away from a lower portion so that the two frame elements communicate through a gap of a separable intermediate portion for mounting the skirt. The frame also has two endpieces for coupling a rear headband therebetween. The clinging device is secured to the separable intermediate portion of the frame by snapping for fastening the whole swim mask.
