Heater for active wear boots

Abstract

An overshoe adapted to be worn over an active wear boot or shoe, such as a ski boot, hiking boot, climbing boot, ice skates and generally any outdoor shoe desired to be protected against the cold environment having a resistance heating element connected to an electrical energy source, said heating element being part of the overshoe, in such a manner as to provide a heat barrier between the overshoe and the active wear boot, conductive leads from the heating element connected to said electrical energy source, preferably a battery and most preferably a rechargeable battery, said energy source preferably having fastening means to fasten said energy source to said active wear boot or to said wearer.

1 . An active-wear boot heater comprising: 
 a protective overshoe for said boot, said overshoe adapted to cover at least a portion of said boot and having fastening means to fasten said overshoe on the said boot,    at least one heating element mounted in or on such overshoe and capable of being activated to a heated state by an energy source, said element being located in said overshoe, fastening means on said energy source for fastening to said boot or said wearer means for energizing said energy source to provide electric current to heat said heating element.    
   
   
       2 . A heater according to  claim 1 , wherein said energy source is a battery  
   
   
       3 . A heater according to  claim 2 , wherein the heating element constitutes a wavy pattern.  
   
   
       4 . A heater according to  claim 3 , wherein the overshoe covers the sides and top of said boot.  
   
   
       5 . A heater according to  claim 4 , wherein the battery is rechargeable.  
   
   
       6 . A heater according to  claim 5 , wherein the battery source provides from 2.5 to 9 volts.  
   
   
       7 . A heater according to  claim 1 , wherein the fastening means of said overshoe are in the form of at least two open straps fastenable to each other by fastening means.  
   
   
       8 . A heater according to  claim 1  wherein the fastening means of said overshoe are in the form of a unitary stretchable band adapted to fit over the heel of the wearer  
   
   
       9 . A heater according to  claim 6  wherein the fastening means of said straps belts with a buckle.  
   
   
       10 . An overshoe adapted to be worn by a wearer over an active wear boot, desired to be protected against the cold environment, having a resistance heating element connected to an electrical energy source, said heating element being part of the overshoe, in such a manner as to provide a heat barrier between the overshoe and the active wear boot, conductive leads from said heating element connected to said electrical energy source, said energy source comprising fastening means to faster said energy source to said active wear boot or to said wearer.
