Modular anti-fog goggle system

Abstract

Modular, anti-fog goggle system comprising: lens with an anti-fog heating element and electrical contact, a semi-rigid anterior body comprising an inner peripheral engagement receptacle for receiving the lens within the body, the lens being releasably retained by a removable lens retaining member preferably comprising a tongue releasably interconnected with a groove in the body, the anti-fog element on the lens being releasably connected with a battery preferably retained within the body, the releasable electrical connection being reinforced by the tongue and groove interconnection, a flexible posterior interface being adapted for interposition between the removable lens retaining member and a user's face, and strap means adapted for holding the goggle on the user's head or helmet and reinforcing the interconnection between the removable lens retaining member and the body.

What is claimed is: 
     
         1 . A modular, anti-fog goggle with a removable lens and adapted for accommodating various weather, lighting and fogging conditions comprising:
 a body having a battery and contact therein and further comprising first and second ends, a semi-rigid outer portion defining an outer opening for field of vision and a semi-rigid interior portion defining an inner opening within the outer portion for field of vision and defining a rear-access socket;   a semi-rigid, semi-transparent lens comprising a peripheral edge, an anterior surface and a posterior surface, said lens residing within the rear-access socket and adapted for being positioned to provide a semi-transparent, shielded view through the outer and inner openings, the lens having a resistive heating element thereon and operatively connected with the battery through the contact;   retaining means having first and second ends, said retaining means for releasably holding said lens within the rear-access socket and for releasably holding the resistive heating element in electrical contact with the battery;   cushioned posterior interface member interposed between one of said lens, said body and said retaining means and a user's face for providing a cushioned structure upon which the goggle is adapted for contacting the user's face; and   strap means having first and second ends, the first end of said strap means interconnected with one of the first end of said body and said retaining means, and the second end of said strap means interconnected with one of the second end of said body and said retaining means, said strap means adapted for holding the goggle on a user's head.   
     
     
         2 . The modular, anti-fog goggle system of  claim 1 , wherein said body further comprises a groove around the inner periphery of the rear-access socket, wherein said retaining means further comprises a tongue around the periphery of said retaining means, and wherein the tongue of said retaining means is inserted into the groove of the rear-access socket to releasably hold the lens in said body and in electrical contact with the battery. 
     
     
         3 . The modular, anti-fog goggle system of  claim 1 , further comprising a battery strength indicator means carried on said body. 
     
     
         4 . The modular, anti-fog goggle system of  claim 1 , further comprising heat adjustment mean on said body and operatively connected with said battery. 
     
     
         5 . The modular, anti-fog goggle system of  claim 1 , further comprising an on/off switch on said body and operatively connected with said battery.
