Goggle lens and face gasket engagement system

1. A goggle having a lens and interchangeable face gasket engagement system comprising:

a. a lens member having a posterior inner surface and first and second ends;

b. latch members pivotably attached to said lens member, one latch member attached adjacent each end of said lens member, each latch member having at least one face gasket member engagement portion;

c. a flexible face gasket member further comprising a plurality of corresponding latch member engagement portions, each latch member engagement portion of said gasket member for engaging a corresponding one of the gasket member engagement portions of said latch members, at least one of said lens member and said flexible face gasket member further comprising a plurality of other alignment protrusions thereon, whereas the other of said lens member and said flexible face gasket member further comprises corresponding receptacles aligned with the other protrusions for aligning and helping to retain said face gasket member with said lens member when engaged thereon; and

d. A strap member having first and second ends, each end interconnected to one of said latch members for securing the goggle lens and face gasket engagement system to a user's head.

2. The goggle of claim 1 , wherein each said face gasket member engagement portion of each said latch comprises a recessed detent area, wherein each said latch member engagement portion of said face gasket member comprises a supple nub protrusion, each supple nub protrusion for engaging a corresponding recessed detention area of a latch member to thus reinforce retention of said gasket member on said lens member.

3. The goggle of claim 2 , further comprising a battery retained on said strap member, said battery retained in a sealed housing having an on/off switch thereon, further comprising a heating element on said lens member, and further comprising upper and lower bus bars interconnecting said heating element and said battery adapted for heating said lens to prevent fogging thereof upon activation by user press of the on/off switch.

4. The goggle of claim 3 , wherein each said upper and lower bus bar is painted on peripheral upper and lower portions of said heating element on said lens member, and wherein contact is made between each said bus bar, said heating element and said lens member by means of a contact member on said bus bar further comprising a rivet extending through said contact member, said bus bar, said heating element and said lens member enabling heating said heating element to prevent fogging of said lens member.

5. The goggle of claim 3 , wherein each said bus bar is retained in a channel member for interconnecting each said bus bar with said heating element, each channel member also retaining at least one contact member for interconnecting each said bus bar with said battery via circuit wiring for heating said heating element to prevent fogging of said lens member.

6. The goggle of claim 5 , further comprising a sealed combination plug, receptacle and wire member for connecting and disconnecting said heating element from said battery.

7. The goggle of claim 6 , wherein said sealed combination plug, receptacle and wire member further comprises a female end on one of said channel member and said wire and a male end on the other of said channel member and said wire.

8. A method of installing an interchangeable face gasket on a goggle lens member comprising the steps of:

a. engaging alignment of face gasket receptacles on lens member alignment protrusions

b. pivotably operating first and second latches each posteriorly from an open position towards a closed position hinged at corresponding ends of the lens member to initially deform corresponding supple nub protrusions on the face gasket upon initial pivoting engagement of the latches with the face gasket;

c. continuing to pivotably operate each latch to deform each of the corresponding supple nub protrusions of the face gasket toward continued engagement of each latch with the face gasket; and

d. finishing pivotable operation of each latch to finally fully engage with each of the latches corresponding supple nub protrusions, each of the supple nub protrusions rebounding into a substantially non-deformation state residing within upper and lower recessed areas of each latch to retain the lens and the face gasket in fully-engaged, but releasable, relationship.

9. A goggle having a lens and interchangeable face gasket engagement system and a multi-point contact electrical contact system adapted for connection with a battery for heating the goggle lens comprising:

a. a lens member having a posterior inner surface and first and second ends;

b. latch members pivotably attached to said lens member, one latch member attached adjacent each end of said lens member, each latch member having at least one recessed detent area;

c. a flexible face gasket member further comprising a plurality of corresponding supple nub protrusions, each supple nub protrusion for residing in a corresponding one of the recessed detent areas of said latch members, at least one of said lens member and said flexible face gasket member further comprising a plurality of other alignment protrusions thereon, whereas the other of said lens member and said flexible face gasket member further comprises corresponding receptacles aligned with the other protrusions for aligning and helping to retain said face gasket member with said lens member when engaged thereon;

d. a strap member having first and second ends, each end interconnected to one of said latch members for securing the goggle to a user's head;

e. a battery retained on said strap member, said battery retained in a sealed housing having an on/off switch thereon;

f. a resistive heating element deposited on a posterior surface of said lens member;

g. upper and lower bus bars for contacting said heating element on said lens member;

h. upper and lower “U”-shaped cross-section non-conductive channel members attached with an open end of each “U” of each said channel member positioned over each said bus bar;

i. a plurality of strategically-located and compressible contact points, the contact points adapted for interconnecting said heating element and said battery via wiring contained partially within said channel members and in a way that said wiring does not contact any said bus bar except at said contact locations within said channel members, said battery thus being adapted for heating said heating element on said lens member upon activation by a user pressing said on/off button.

10. The goggle of claim 9 , further comprising a sealed combination plug, receptacle and wire member for connecting and disconnecting said heating element from said battery.

11. The goggle of claim 10 , wherein said sealed combination plug, receptacle and wire member further comprises a female end on one of said channel member and said wire and a male end on the other of said channel member and said wire.
