Hermam Chlang Spruson Ferguson, Patent Attorneys Level 33 St Martins Tower, 31 Market Street Sydney, New South Wales, 2000, Australia Swimming Goggles with Air Cushion Pad The following statement is a full description of this Invention, including the best method of performing it known to me/us:- 5845 SWIMMING GOGGLES WITH AIR CUSHION PAD FIELD OF THE INVENTION The present invention relates generally to swimming goggles and in particular to a swimming goggle structure that incorporates an air cushion pad for a more comfortable and compliant engagement with the wearer's face.

BACKGROUND OF THE INVENTION To provide a comfortable engagement with the wearer's face, swimming goggles are usually provided with a cushion pad of resilient material mounted to each of the lens frames of the goggles to be in resilient contact with the wearer's face around the eye sockets. Conventionally, the swimming goggle cushion pads have two types. The first one is made of a foamed material and the second one comprises a collapsible suction cup like configuration made of a resilient material. These two different types of cushion pad provide different capabilities in comfort of face engagement and leakage proofness. The foamed material type cushion pad, 15 although being made as a block, offers a very comfortable engagement with the *.*wearer's face due to the soft nature of the foam material used to make the cushion pad. In addition, the foamed material that is used to make the cushion pad also allows heat generated by the wearer's face skin to be dissipated so that an even greater comfort may be provided to the wearer's face skin. However, due to the fact that the foamed material that is used to make the cushion pad is generally in the form of a block which does not allow an excellent compliance with the face contour of the wearer so as not to provide a good leakage proof engagement with the wearer's face.

Thus leakage may occur and water may gradually get into the swimming goggles.

The suction cup type cushion pad is usually made of rubber or non-foamed 25 thermoplastic plastics which provides an excellent water leakage proof property.

The suction cup type cushion pad usually has a J-shaped cross section having a very S thin flange for face contact engagement which allows an instant collapse upon contact S with the wearer's face so as to be very compliant to the wearer's face contour for an excellent water leakage proofness. The suction cup type cushion pad, although possessing a good water leakage proof property, yet may not be suitable for everybody's face contour for the face contour is different from person to person.

Water leakage problem is thus not completely overcome by the collapsible ssuction cup type cushion pad.

Thus, it is desired to provide an air cushion pad for swimming goggles which has the advantages of both the foamed material type cushion pad and the collapsible suction cup type cushion pad so as to overcome the problems encountered in the prior art.

SUMMARY OF THE INVENTION An object of the present invention is to provide an air cushion type swimming goggle cushion pad, which by means of the compressibility and fluid flow characteristics of the air filled in the cushion pad, provides an excellent compliant engagement with the wearer's face contour that is not only capable to accommodate different face contours, but may also very comfortably engages the wearer's face to provide a very comfortable and very water leakage proof swimming goggle cushion pad structure.

Thus, to achieve the above objects, in accordance with the present invention, an air cushion pad structure of swimming goggles is provided, comprising a connection portion that is attached to each of the lens frames of the swimming goggles and a cushion body which is a hollow sealed member with air filled therein to provide compressibility and collapsibility. The cushion body has a face engaging surface which is capable to very comfortably engage with the wearer's face due to the collapsibility thereof and to very compliantly follow the wearer's face contour for an excellent water leakage proofness due to the compressibility thereof In accordance with the present invention, the face engaging surface of the cushion body has an arc configuration to provide an even better compliance with the :eeoee wearer's face contour.

The objects, advantages and features of the present invention will be apparent 25 from the following description of preferred embodiments thereof, with reference to the attached drawings, wherein: BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view, partially exploded, showing a pair of swimming goggles on which an air cushion pad structure in accordance with the present invention is mounted; Figure 2 is a cross-sectional view taken along line H-H in Figure 1; Figure 3 is a perspective view showing a pair of swimming goggles in which an air cushion pad in accordance with a second embodiment of the present invention is incorporated; Figure 4 is a cross-sectional view taken along line 111-111 of Figure 3; Figure 5 is a perspective view showing a pair of swimming goggles incorporating the air cushion pad of the present invention; and Figure 6 is a perspective view, partially exploded, showing a pair of swimming goggles on which an air cushion pad for swimming goggles in accordance with a further embodiment of the present invention is mounted.
