  • Patent number: 5890237
    Abstract: A swimming goggle structure includes lens frames, lenses, cushion pads and a head strap. The cushion pads of the swimming goggles include a collapsible layer and a resilient layer. The collapsible layer has a cushioning portion and a connection portion. The cushioning portion is mounted to the lens frame and is collapsible. The connection portion is connected to the resilient layer. The resilient layer is made of a resilient material, such as foam materials, for example foam rubber and foam plastics, and sponge. The collapsible layer collapses upon worn on the wearer's face to create a negative pressure suction inside the goggles. The resilient layer provides a comfortable engagement with the wearer's face and also provides a water-tight, hermetic contact engagement with the wearer's face.
