Goggle contoured for helmet engagement

Abstract

A goggle ( 12 ), shaped to conform to a human face includes a body defining a top wall ( 19 ) and sidewalls ( 21 ) dimensioned to form a continuous contour which closely matches the shape and size of a facial aperture ( 41 ) formed in a helmet ( 38 ), thereby to form a smooth, contoured combined goggle and helmet exterior surface. At least one air intake aperture ( 24, 25, 26 ) communicates through the goggle lens ( 16 ) or goggle body to an eye cavity ( 18 ). At least one venting aperture ( 30 ) communicates through the sidewalls ( 12 ) of the goggle body with the eye cavity ( 18 ).

1 . A helmet engageable goggle comprising: 
 a goggle body having an exterior surface and an interior surface and having a lens aperture surrounded by a top wall, a bottom wall, and two sidewalls;    a lens mounted in said lens aperture;    an eye cavity defined by the area between said interior surface, said lens, said top wall, said bottom wall and said two sidewall;    at least one intake aperture communicating through said lens or said goggle body with said eye cavity;    at least one side venting aperture communicating through one of said sidewalls of said goggle body with said eye cavity;    said top wall and said sidewalls dimensioned to form a single contiguous contour;    said single contiguous contour adapted to substantially abut with the top edge and side edges of a facial aperture formed in a helmet when said goggle is engaged in said facial aperture; and    means to attach said goggle to a helmet.    
   
   
       2 . The helmet engageable goggle of  claim 1 , wherein said attachment means comprising an elastic line extending from the goggle sidewalls to engage an anchor disposed on a helmet.  
   
   
       3 . The helmet engageable goggle of  claim 2 , wherein said anchor having an enlarged head portion standing out from a helmet to define a shoulder for receiving the elastic line.  
   
   
       4 . The helmet engageable goggle of  claim 1 , wherein said attachment means comprising at least one pin projecting from the goggle sidewalls to engage receiving sockets formed in a helmet.  
   
   
       5 . The helmet engageable goggle of  claim 1 , further comprising: 
 an exterior surface of said goggle sidewall dimensioned to create a low air pressure area immediately adjacent to said side venting aperture when moving air travels over said exterior surface, whereby air flow exhausting from said eye cavity through said side venting aperture is enhanced by the force of said low pressure area acting to draw higher pressure air in said eye cavity out through said side venting aperture.    
   
   
       6 . The helmet engageable goggle of  claim 1 , further comprising: a helmet; 
 said helmet having a facial aperture, said facial aperture having a top edge and two side edges; and    said helmet top edge and two side edges substantially formed to mate with said single contiguous contour of said goggle.    
   
   
       7 . The helmet engageable goggle of  claim 6 , further comprising: 
 an exterior surface of said goggle sidewall dimensioned to create a low air pressure area immediately adjacent to said side venting aperture when moving air travels over said exterior surface during engagement of said goggle in said facial aperture, whereby air flow exhausting from said eye cavity through said side venting aperture is enhanced by the force of said low pressure area acting to draw higher pressure air in said eye cavity out through said side venting aperture.    
   
   
       8 . A helmet and goggle combination, comprising: 
 a. a helmet comprising a facial aperture defined by a top edge portion and side edge portion to form a contiguous contour;    b. a goggle comprising: 
 a body shaped to define an exterior side and an interior side, said body also defining a lens aperture formed by a top wall, a bottom wall and two sidewalls;  
 the lens mounted in said lens aperture;  
 an eye cavity defined by the area between said body interior surface, said lens, said top well, said bottom well, and said two sidewalls;  
 said goggle body top wall and sidewalls configured to form a single continuous contour, said single continuous contour shaped and sized to substantially abut with the top end side edge portions of the facial aperture of said helmet when said goggle is engaged with said facial aperture;  
 at least one intake aperture communicating through said lens or said goggle body with said eye cavity; and  
 at least one venting aperture communicating through said goggle body with said eye cavity; and  
   c. means to attach said goggle to said helmet.    
   
   
       9 . The combination of  claim 8 , wherein said at least one venting aperture communicating through at least one of said sidewalls of said goggle body.  
   
   
       10 . The combination of Clam  9 , further comprising an exterior surface of said goggle sidewall dimensioned to create a low pressure area immediately adjacent to said sidewall venting aperture, wherein when moving air travels over said exterior surface, the air flow exhausting from said eye cavity through said venting aperture is enhanced by the force of said low pressure area acting to draw high pressure air disposed in said eye cavity out through said venting aperture.  
   
   
       11 . The combination according to  claim 8 , wherein said attachment means comprising an elastic cord extending from the goggle sidewalls to engage an anchor disposed on said helmet.  
   
   
       12 . The combination according to  claim 10 , wherein said anchor having an enlarged head portion disposed outwardly from said helmet to define a shoulder portion between said enlarged head portion and said helmet for receiving the elastic cord.  
   
   
       13 . The combination according to  claim 8 , wherein said attachment means comprising at least one pin projecting from said goggle body sidewalls to engage close-fitting sockets formed in adjacent portions of said helmet, when said goggles are engaged with said facial aperture of said helmet.
