Abstract
A hand warmer comprising: a tubular sleeve having two extremities located along a longitudinal axis thereof, said sleeve defining a longitudinal opening therein, each extremity having defining an opening adapted to receive hands; a heating element; and a battery operatively connected to the heating element; wherein said tubular sleeve comprising an inner wall and an outer wall and adapted to receive the battery between the inner and outer wall and wherein the heating element is located within the longitudinal opening and is adapted to be grasped by a hand when such is inserted into the longitudinal opening of the hand warmer.
Claims9
A hand warmer comprising:
- a tubular sleeve having two extremities located along a longitudinal axis thereof, said sleeve defining a longitudinal opening therein, each extremity defining an opening adapted to receive hands;
- wherein said tubular sleeve comprises an inner wall and an outer wall;
- a flexible handlebar-shaped heating element that comprises a heating wire that is encased in a thin, flexible heating pad, the flexible handlebar-shaped heating element adapted to be grasped by a hand or hands when inserted into the longitudinal opening, the flexible handlebar-shaped heating element is secured to the inner wall of the tubular sleeve at both ends of the handlebar-shaped heating element,
- wherein the flexible handlebar-shaped heating element is formed from the thin, flexible heating pad, the heating wire of the thin, flexible heating pad connected to a battery, and
- wherein the entire flexible handlebar-shaped heating element is flexible.
