SWIM GOGGLES
ABSTRACT OF THE DISCLOSURE
Swim goggles have a pair of eye pieces, each eye piece having a lens with an essentially rigid peripheral frame. Each eye piece has a seal assembly which includes a seal holder and a seal gasket. The seal holder is secured to the frame and has a pair of spaced flanges extending in a direction generally away from the respective lens. Space between the flanges of the seal holder provides a groove extending around the eye piece and the seal holder is resiliently deformable but relatively stiff. The seal gasket is fitted within the space between the flanges and has an outer face standing clear of the flanges to contact the wearer's face. The seal gasket is resiliently deformable and softer than the seal holder to provide a secure but comfortable seal with the wearer's face. Selection of the relative resiliences of the seal holder and seal gasket permits accommodation to a wide variety of faces and extends use of the goggles. A swim mask with single lens provided with a seal assembly as above is an alternative.

Description
~294389 BACKGROUND OF THE INVENTION
Field of the Invention The invention relates to goggles for eye protection which are particularly adapted for, t)ut not limited to, swimming.
Prior Art Many varieties of swim goggles have Deen available to accommodate the variations between wearer's faces. Swim goggles should provide a good seal against water penetration, as well as being comfortable for extended wear. It is known to provide a resilient seal or gasket made from an expanded elastorner or rubDer compound which extends from tile rigid frame of the goygles to contact the face. The seal is adapted to engage recesses and Dulges of the face, so as to provide a water-tight nut comforta~le fit.
If the seal is excessively soft, it usually deteriorates quickly in the chlorinated water commonly used in swimming pools. Soft seal gas~ets can deform under a relatively low force Which seems to l~e neCessary for comfort when fitted directly against the face, and can deform in a direction normal to th0 face to accommodate curvature of the face. However, exces9ively soft seals which project too far from a riyid base can deform excessively in a direction parallel to the face i.e., fold over, which can reduce effectiveness of the seal and permit leakage.
Harder types of seals require a greater force to deform them to fit the face, and correspondingly can become uncomfortable after a short time. The rnore rigid seals tend to resist deterioration better than the softer seals, and do not deform excessively but, in general, cannot accommodate such a wide variety of curvatures of the face. In general~ goggles for long distance -2~ 43~9 training swimming are soiter ~or greater comfort than go~gles used for rQcing Raci~g goggles must be sufficiently sti~i to resist the shock forces of a racing dive, and thus comfort is often sacrificed because such goggles are usually worn for shorter periods.
U.S. Patent 1,850,538 issued to Dickson in March 1932 and U.S.
Patent 1,741,427 issued to Meyrowitz in December 1929 disclose goggles having seals of the resilient cushion type, but these goggles do not appear to be suitable for swirnming. The seals of these goggles can be easily replaced when worn, but the structure for attaching the seals to the frame of the goggles is such that the goggle seals can accidentally be dislodged from the goggles, which could cause leakage, become uncomfortable and even distort vision through the goggles. U.S. Patent 2,393,533 issued to Heinz in January 1946 discloses a resilient seal for swimming goggles which is a hollow tube extending around the rim of the eye pieces.
The tube is formed from a relatively stiff elastomeric compound, bUt its cross-section and thin walls permits it to deform to accommodate variations in the face.
To the inventor's knowledge, none of the prior art goggles provide a seal which combines the comfort of the resilient soft, low density elastomeric cushion foam with the stiffness and accuracy of location arising from use of the stiffer, higher density elastomeric materials. To the inventor's knowledge, none of the prior art goggles provides a seal which can accommodate the wide variability of the h~man face, be comfortable, resist the shock loads of a racing dive, and water resistant and also permit easy replacement o~ a worn soft seal.
SIJ~II~RY OF THE INVENTION
~he invention provides a sealfor goggles which reducesthe difficulties and 35 disadvantages of the p~ior art by providing a seal assemrly of cornposite materials. The seal assernbly includes a combination of a relatively stiff 129~389 material which provides a degree of resilience to accommodate the larger curvatures of the face, without excessive distortion, and a softer material which contacts the face to provide comfort and a yielding seal to accommodate smaller variations in curvature of the face. In effect, there is a gradual change in stiffness from the essentially rigid peripheral frame of the lens, through an intermediate semi-resilient material to the softness of the cushion seal which actually contacts the face. By correct selection of seal materials, the invention provides swim goggles which can be used with a soft seal for training, and a harder seal can be su~stituted for racing.
Swim goggles according to the invention have a pair of eye pieces, with each eye piece having a lens with an essentially rigid peripheral frame. A nose strap and the head strap interconnect the eye pieceS at inner and outer end portions respectively of the fràmes, as is common practice. Each eye piece has a seal assembly which includes a seal holder and a seal gasket. The seal holder is secured to the respective frame and has a pair of spaced flanges extending in a direction generally away from the respective lens. Space between the flanges provides a groove extending around the eye piece. The seal holder is resiliently deformaDle but relatively stiff. The seal gasket is 2û fitted within the groove between the flanges and has an outer face standing clear of the flanges and is adapted to contact the wearer's face. The seal gasket is resiliently deformable and softer than the seal holder so as to provide a secure but comfortable seal with the wearer's face. In one emDodiment the frame of each eye piece has engaging means to cooperate with the seal holder, the engaging means being a L-sectioned lug extending around the frame. The seal holder has an inner portion which has a L-sectioned recess complementary to the L-sectioned lug and adapted to receive the L-sectioned lug. In an unrestrained condition, the groove has a re-entrant cross-section with an inner width between the flanges greater than an outer width between the flanges, so as to grip the seal gasket theret~etween, - 12943~9 A single lens face mask with an essentially rigid peripheral frame can be fitted with a seal assembly aocording to the invention to provide a face mask which is more appropriate for Scuha diving.
A detailed disclosure followhlg, related to drawings, describes a preferred embodiment of the invention which is capable of expression in structure other than that particularly described and illustrated.
DESCRIPTION OF THE DRAWINGS
Figure 1 is a simplified, fragmented front view of a pair of swim goggles fitted with a seal assem~ly according to the invention, Figure 2 is a fragmented top plan of one eye piece portion of the goggles of Figure 1, Figure 3 is a simplified fragmented section on line 3-3 of Figure 1, showing a seal assemrly with a seal holder and seal gasket according to the invention, Figure 4 is a simplified fragmented section, generally as would ~e seen on line 3-3 of Figure 1, with the seal gasket removed from the seal holder so that the seal holder is in an unrestrained condition, Figure 5 is a simplified cross-section through a seal gasket of the invention in an unrestrained condition.
Figures 1 and 2 Swim goggles 10 according to the invention have first and second eye pieces lZ94389 11 and 12, a nose strap 13 and a head strap 14. The nose strap interconnects adjacent inner end portions of the frames as shown, and Dridges the nose, not shown, of a wearer, and the head strap 14 interconnects outer end portions of the frames and passes around the ~ack of the head as is common practice. The eye piece 11 has a transparent lens 17 and an essentially rigid peripheral frame 1~. Pre~erably, for manufacturing simplicity and for improved peripheral vision, the eyepiece and frame are integral and thus the frame is also transparent. The frame 18 has inner and outer portions 21 and 22 which provide releasable anchor means 25 and 26 respectively for the nose strap and head strap 13 and 14 respectively. The eye piece 11 has a seal assemDly 23 according to the invention provided on a side of the frame 18 remote from the lens so as to contact the wearer's face, not shown.
The eye piece 12 has structure generally similar to the eye pieee 11, and is a rnirror image thercof and is not descri~ed in detail.
Fiqures 3 throuqh 5 2û The seal assembly 23 includes a seal holder 28 and a seal gasket 30. The frame 18 has a L-sectioned lug 32 extending around the frame as ~est seen in Figure 3. The L-sectioned lug faces inwardly around the peripheral frame and the seal holder 28 has an inner portion 35 which has an L-sectioned recess 37 which is complementary to the L-sectioned lug 32 and is adapted to receive the L-sectioned lug. Thus, the L-sectioned lug of the frame serves as an engaging means to cooperate with the seal holder and, if desired, the frame and seal holder can ~e integrally molded together. The lug and seal holder can have other complementing shapes so that the inner portion of the seal holder is adapted to cooperate with the engaging means of the frame.
Ths seal holder 28 has an outer portion having inner and outer flanges 41 and 42, and an intermediate portion 45 disposed t)etween the inner and outer portions of the flange. The flanges 41 and 42 extend in a direction generally away from the respective lens 17 and have respective flange roots 47 and 48 adjacent the intermediate portion, and flange tips 51 and 52 at outer extremities of the flanges. As t~est seen in Figure 4, in the unrestrained conditiorl, an outer width 54 between the flange tips is less than an inner width 56 between the flange roots. It can ~e seen that space ~etween the flanges provides a groove 58 extending around the eye piece, the groove having a depth 57. Thus, the groove 58 has a re-entrant cross-section with the inner width 56 between the flanges being greater than the outer width 54 between the flanges.
The seal gasket 30 has an inner portion 64 fitted in the groove 58 between the flanges and has an oUter portion 59 having a relatively flat oUter face 60 standing clear Of the flanges ~y a distance 62, The distance 62 iS sufficient to permit only lill~ited lateral deformation Of the outer portion 59 of the sealgasket i~e.~ parallel to the face to accommodate contours of the wearer's face. Slight lateral deformation of the outer portion 59 of the seal gasket 30 iS shown in broken outline at 59.1. When the seal is laterally deformed, an effective watertight seal with the face is not lost because the outer face 60 rernains relatively flat and in contact with the wearer's face 63, shown in broken outline. The seal gasket is resiliently deformable and fabricated from an expanded or foamed elastomer as will be described. It is softer than the seal holder so as to provide a secure but comfortable seal with the wearer's face. It can be seen that relative stiffeners of the three components of the goggles increases in a direction away from the face, i.e., the softest components are closest to the face.
As seen in Figure 5, the seal gasket 30 is shown in the unrestrained condition and the inner portion 64 has a width 66 which is greater than the inner width ~ ~9~38~
56 of the groove 58 in the unrestrained condition as seen in Figure 4. The seal gasket can be die cut from a flat sheet and is generally rectangular in cross-section when unrestrained. An inner face 65 of the gasket can be provided with a "low tack" contact adhesive which can releasably bond to the portion 45 o~ the seal holder so as to augment retention of the seal gasket in the seal holder. The seal gasket can oe removed fron~ the holder with a negligiole deposit of the "low tack" adhesive remaining on the seal hol der.
Prefera~ly, the seal gasket 30 has a depth 68~ see Figure 5, which is approximately twice the depth 57 of the groove 58. In this wa~, approximately half the depth of the seal is gripped and retained by the flanges, and the remaining half stands proud of the flanges and can accommodate contours of the face, while simultaneously providing a soft uncomforta~le seal. Preferably~ the flanges are curved inwardly towards each other in the unrestrained condition as seen in Figure 4, so as to grip the seal gasket therebetween at a location on the seal gasket intermediate of inner and outer faces of the seal gasket.
Material Considerations The effectiveness and comfort of the seal of the present invention is dependent on the correct selection of materials for the two components of the seal assem~ly. The seal holder 2a is molded from thermoplastic ru~er compounds which are resilient and yet relatively stiff. SuitaDle materials are manufactured by Shell Chemical Inc., under the trade mark KRATON D
and KRATON G, and particular specifications of suitable compounds are as follows.
Hardness [Shore A(D-2240)] 35 through 95.
Tensile strength [D-412] PSI 500 through 2500 300~/o Modulus, PSI 300 to 1400 Elongation /,, 600 to 700 Tear resistance [ die C ] PLI (D- 624) 95 through 550 Yerzly resilience [ 3% (D-945) ] 71 through 75 lZ94389 The typical properties outlined at)ove for the KRATON G 2705, G-7705, G-7720, G-7820 and G-7827 are summarised for typical properties at 74 degrees Farenheit (23 degrees Centigrade). SuCh compounds have excellent ozone resistance which is essential for use in chlorinated water as is well known in the trade.
The seal gasket 30 can be manufactured by cutting from flat sheets of high density cellular polyurethane, sold under the trade mark PORON, as manufactured t)y the Rogers Corporation of East Woodstock, Connecticut.
Iû Other suital~le compounds include RUBBERTEX, registered trade mark of Rul~bertex Corporation of Virginia, U.S.A., and ENSOLITE, a registered trade mark of Uniroyal Plastics Co., Inc., of Indiana U.S.A. A "low tack"
contact adhesive can ~e applied to one side of the sheet to improve retention of the seal gasket within the seal holder.
Typical properties of suitat)le seal gasket material are summarised belOW.
Compression deflection (PSI ) 2 - 10 Hardness Shore 00 Durometer 10-50 to Shore Resilience (Bashore) ~o Reoound Average 4û-60 Tensile strength and elongation are not very important properties for the seal gasket as the seal gasket is supported by the seal holder. This permits use of a relatively soft gasket material when compared with prior art 30 gaskets. Materials are selected also for their aging properties, and ozone and chlorination resistance as well as tendency to resist adhering to the face .
g OPERATION
The goggles are used in a normal manner, by adjusting the spacing between the eye pieces by careful adjustment of the nose strap. Similarly, the force of the goygles against the face is adjusted by the head strap 14.
For racing use, goggles are usually worn for only a short time, and the seal must withstand the forces of a racing dive. Thus a relatively stiff seal gasket, and correspondingly stiffer seal holder are preferred. For training purposes, where forces are lower, and the goggles are worn usually for a longer time, comfort is preferred and correspondingly softer materials are selected for the seal holder and seal gasket. Alternatively the same goggles and seal holder can be used for both training and racing, and only the seal gasket need Oe changed for the different activities. In general, the seal gasket will deteriorate far faster than the seal holder, and it is relatively easy to replace a worn or deteriorated seal gasket wit!- a new one.
ALTERNA~IVES AND EQUIVALENTS
A face mask with a single lens can ~e fitted with a seal assembly according to the invention and obtain the benefits of comfort, accuracy of sealing fit and easy replacement or material su~stitution of the seal gasket. This type of masl< is particularly appropriate for Scuba diving, and clearly requires only a head strap interconnecting opposite sides of the masl<, the nose strap oeing eliminated.

Figures 1 and 2 Swim goggles 10 according to the invention have first and second eye pieces lZ94389 11 and 12, a nose strap 13 and a head strap 14. The nose strap interconnects adjacent inner end portions of the frames as shown, and Dridges the nose, not shown, of a wearer, and the head strap 14 interconnects outer end portions of the frames and passes around the ~ack of the head as is common practice.

The eye piece 12 has structure generally similar to the eye pieee 11, and is a rnirror image thercof and is not descri~ed in detail.
Fiqures 3 throuqh 5 2û The seal assembly 23 includes a seal holder 28 and a seal gasket 30. The frame 18 has a L-sectioned lug 32 extending around the frame as ~est seen in Figure 3. The L-sectioned lug faces inwardly around the peripheral frame and the seal holder 28 has an inner portion 35 which has an L-sectioned recess 37 which is complementary to the L-sectioned lug 32 and is adapted to receive the L-sectioned lug.

Compression deflection (PSI ) 2 - 10 Hardness Shore 00 Durometer 10-50 to Shore Resilience (Bashore) ~o Reoound Average 4û-60 Tensile strength and elongation are not very important properties for the seal gasket as the seal gasket is supported by the seal holder. This permits use of a relatively soft gasket material when compared with prior art 30 gaskets. Materials are selected also for their aging properties, and ozone and chlorination resistance as well as tendency to resist adhering to the face .
g OPERATION
The goggles are used in a normal manner, by adjusting the spacing between the eye pieces by careful adjustment of the nose strap. Similarly, the force of the goygles against the face is adjusted by the head strap 14.
For racing use, goggles are usually worn for only a short time, and the seal must withstand the forces of a racing dive. Thus a relatively stiff seal gasket, and correspondingly stiffer seal holder are preferred. For training purposes, where forces are lower, and the goggles are worn usually for a longer time, comfort is preferred and correspondingly softer materials are selected for the seal holder and seal gasket. Alternatively the same goggles and seal holder can be used for both training and racing, and only the seal gasket need Oe changed for the different activities. In general, the seal gasket will deteriorate far faster than the seal holder, and it is relatively easy to replace a worn or deteriorated seal gasket wit!- a new one.
ALTERNA~IVES AND EQUIVALENTS
A face mask with a single lens can ~e fitted with a seal assembly according to the invention and obtain the benefits of comfort, accuracy of sealing fit and easy replacement or material su~stitution of the seal gasket. This type of masl< is particularly appropriate for Scuba diving, and clearly requires only a head strap interconnecting opposite sides of the masl<, the nose strap oeing eliminated.
