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-envelope 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 like 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 at item “

a”

above, 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 the approximate curvature of a normal, at rest, adult shoulder—

that is the same length as the length of the rectangular center panel in item “

a”

above, with heating elements sandwiched within each triangular side panel, with the curved edge 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. heating elements that transverse throughout each of the three panels in general parallel lines, interconnected at only one end of the attachment of the three panels, allowing full ‘

drapability’

of the completed device;

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

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

3. The heating pad of claim 1 includes an adjustable holding belt, attached at each end to the distal corners of the completed device. Variable sizes are accomplished via an adjustable ‘

non-slip buckle’

, thereby accommodating a small woman or a large man.
