Abstract

An electric heating device that is constructed in a unique fashion that allows it to be drapeable so that its three-dimensional, ‘scoop-like’ shape fits the curvature of a relaxed shoulder, a crooked knee or a crooked elbow, and is held in place by an adjustable strap whose ends are attached to the device. The heating element configuration that is contained within a singular, sealed, water-tight vinyl envelope that is produced as one piece, with the three panels briefly connected at a point where the heating element wiring crosses from one panel to the other.

Claims

1. An electric heating device comprising:

a. a center rectangular panel with a width of approximately 3½

inches to 4½

inches and a length of approximately 14 inches to 16 inches, formed of front and back panels of a suitable fabric material, with a heating element sandwiched therein;

b. two triangular side panels, formed of front and back panels of the same fabric material as the rectangular panel, each with two straight-cut edges of equal lengths of approximately 11 inches to 13 inches and one curved edge that is cut in an arch of a normal curvature of a normal, at rest, adult having the same length as the length of the rectangular center panel, with heating elements sandwiched within each triangular side panel, with the curved edges of the triangular side panels attached to each of the 14 inches to 16 inch edges of the rectangular panel, to create a curved, scoop-like, three dimensional structure;

c. said heating elements that transverse throughout each of said rectangular and triangular side panels in general parallel lines, interconnected at only one end of a attachment of said rectangular and triangular side panels, allowing full ‘

drapability’

of the completed device;

d. an electrical connection from said heating elements to a power source, and a manual control in said electrical connection including on-off positions and two or more heat settings.

2. The heating device of claim 1 wherein heating elements of said rectangular and triangular side panels are enclosed within one singular form-fitting waterproof vinyl cover, allowing for the use of a moistened cloth, which when placed between the device and the user'"'"'s skin, causes a desired moist heat effect.

3. The heating device of claim 1 includes an adjustable holding belt, attached at each end to the distal corners of said triangular side panels, variable sizes are accomplished via an adjustable ‘

non-slip buckle’

, thereby accommodating a small woman or a large man.
