Headgear having airflow characteristics

Abstract

A visor or cap brim is disclosed that prevents the pressure of the wind from blowing the cap off of the user's head. The visor portion is a generally planar surface that is held out away from the front of the cap portion that sits on the user's head. This creates a single large passage between the visor/bill and the cap and the visor/bill is held at such an angle that it acts a “spoiler” to press the hat down more firmly on the user's head in a high wind while at the same time shading the eyes and forehead from the sun. The visor portion of the cap is removably attached to a semi-rigid headband that encircles the base of the main body of the cap. This attachment is accomplished by a plastic “rivet” type arrangement connected at the terminal ends of a pair of arms attached to the novel visor portion. The visor portion includes a wind or air dam along its upper edge to increase stability and is also slidable up and down the arms.

1 . An article of headgear comprising: 
 a main body portion adapted to fit on a user's head, said main body portion further including a semi-rigid headband portion, said semi-rigid headband portion defining a plane on which it generally lies, and where said semi-rigid headband portion also includes two laterally located side portions and a front portion;    a visor portion having attachment means for attaching said visor portion to said main body portion and where said visor portion further includes a main visor body portion, said main visor body portion being generally planar, said visor portion also including;    a pair of arms, each one of said arms having a first end and a second end, each said first end being attached to said main visor body portion and each said second end including said attachment means and where said semi-rigid headband portion also includes receiving areas on said laterally located side portions, and where each arm also extends parallel to said semi-rigid headband between said first end and said second end; and    where said attachment means comprises a rivet-type attachment and said receiving means on said semi-rigid headband comprises a pair of apertures and where a second set of cooperating and aligned apertures is provided on each of said arms; whereby    said visor portion is attachable to said main body portion of said headgear at a predetermined angle to said plane of said semi-rigid headband portion by said removable attachment means and thereby an article of headgear with airflow characteristics is formed.    
   
   
       2 . The headgear according to  claim 1 , wherein said predetermined relationship is an angle of between 25° and 65°.  
   
   
       3 . The headgear according to  claim 1 , wherein said visor portion includes a top trailing edge, said top edge further including a wind dam extending at substantially a right angle to said visor portion.  
   
   
       4 . The headgear according to  claim 1 , wherein said visor portion is slidably attached to said pair of arms.
