Helmet mounted fan

Abstract

A helmet-mounted fan, including a main body that includes a fan assembly having at least two fan blades each including a foldable joint, a motor operatively coupled to the fan assembly, and a power supply, operatively coupleable to deliver power to the motor and configured to drive rotation of the fan when the power is delivered. A clip-on fastener releasably secures the fan assembly, motor and power supply to a helmet. The clip-on fastener including a generally planar base portion and a deformable, arcuate member extending from the base portion, wherein the base portion and arcuate member together define a clamp area that will tightly receiving the brim, visor or brow guard of a helmet, hat or other headwear to releasably secure the fan assembly to the helmet, hat or other headwear.

1 . A helmet-mounted fan, comprising:
 a main body, comprising:
 (i) a fan assembly having at least two fan blades, the at least two fan blades each including a foldable joint, 
 (ii) a motor operatively coupled to the fan assembly, and 
 (iii) a power supply, operatively coupleable to deliver power to the motor and configured to drive rotation of the fan when the power is delivered; and 
   a clip-on fastener for releasably securing the fan assembly, motor and power supply to a helmet, the clip-on fastener comprising a generally planar base portion and a deformable, arcuate member extending from the base portion, wherein the base portion and arcuate member together define a clamp area that will tightly receiving the brim, visor or brow guard of a helmet, hat or other headwear to releasably secure the fan assembly to the helmet, hat or other headwear.   
     
     
         2 . The helmet-mounted fan of  claim 1 , further comprising a moveable joint disposed between the clip-on fastener and the main body that allows the position of the helmet-mounted fan to be adjustable relative to the helmet. 
     
     
         3 . A helmet-mounted fan, comprising:
 a fan assembly having at least two fan blades;   a motor operatively coupled to the fan assembly;   a power supply, operatively coupleable to supply power to the motor and drive rotation of the fan; and   means for releasably securing the fan assembly, motor and power supply to a helmet.   
     
     
         4 . The helmet-mounted fan of  claim 3 , wherein each of the at least two fan blades comprises a foldable joint near a base of each fan blade, allowing the fan blades to be positioned in a stowed configuration when not in use. 
     
     
         5 . The helmet-mounted fan of  claim 3 , wherein the fan blades are circumferentially enclosed within a protective fan cover. 
     
     
         6 . The helmet-mounted fan of  claim 3 , wherein the means for releasably securing is a clip-on fastener. 
     
     
         7 . The helmet-mounted fan of  claim 6 , wherein the clip-on fastener comprises a generally planar base portion and a deformable, arcuate member extending from the base portion, wherein the base portion and arcuate member define a clamp area for tightly receiving the brim, visor or brow guard of a helmet, hat or other headwear to removeably secure the fan assembly to the helmet, hat or other headwear. 
     
     
         8 . The helmet-mounted fan of  claim 3 , wherein the means for releasably securing means comprises a hook and loop fastener. 
     
     
         9 . The helmet-mounted fan of  claim 3 , wherein the means for releasably securing comprises an adhesive. 
     
     
         10 . The helmet-mounted fan of  claim 3 , wherein the means for releasably securing comprises a mechanical fastener. 
     
     
         11 . The helmet-mounted fan of  claim 3 , wherein the means for releasably securing comprises a spring clamp. 
     
     
         12 . The helmet-mounted fan of  claim 3 , wherein the means for releasably securing comprises a stretch band that wraps around the top of the helmet. 
     
     
         13 . The helmet-mounted fan of  claim 3 , further comprising a moveable joint which allows the position of the helmet-mounted fan to be adjusted relative to the helmet.
