Abstract

A therapeutic heating sleeve (10) consisting of a laminate pad (20) with an exterior cover (22), a batting (24), a polyester lining (26), a heating wire (28) and an interior lining (30) having a hook and loop fastener (32) that is attached on the exterior cover (22) and the interior lining (30). The laminate pad (20) has a lower portion that is in the shape of a human arm and an upper portion that is in the shape of a human shoulder. The heating sleeve (10) is completed by overlapping the pad'"'"'s right side onto the pad'"'"'s left side and attaching the two sides with the hook and loop fastener (32), thereby forming an open-ended sleeve. An electrical control is removably attached to the laminate pad (20) for applying electrical energy to the heating wire (28), thereby creating heat for baseball pitchers to warm up their arm and shoulder prior to pitching.

Claims

1. A therapeutic heating sleeve comprising:

a) a laminate pad having;

1) an exterior cover of a woven fabric cloth lamina,

2) an insulating batting lamina, disposed onto the exterior cover for retaining heat within the sleeve,

3) a polyester lining disposed onto the insulating batting lamina,

4) a flexible resistance heating wire disposed in a winding path onto the polyester lining for supplying heat within the sleeve,

5) a soft woven fabric interior lining disposed on the heating wire, and

6) a length of hook and loop fastener that is attached in opposed positions on an outer surface of the exterior cover and the interior lining through the insulating batting and polyester lining, wherein said laminate pad having a lower portion in the shape of a human arm and an upper portion in the shape of a human shoulder with each portion having a right side and a left side, with the therapeutic heating sleeve completed by juxtapositioning the laminate pad right side onto the laminate left side and overlapping the hook and loop fastener together, thereby forming an open-ended sleeve, and

b) an electrical control that is removably attached to said laminate pad for applying electrical energy to the resistance heating wire, thereby creating heat for baseball pitchers to warm up their arm and shoulder prior to pitching.

2. The therapeutic heating sleeve as recited in claim 1 wherein said exterior cover is fabricated of a non-flammable material that is selected from the group consisting of cotton cloth, cotton and polyester blend cloth, rip-stop nylon, neoprene coated polyester, chlorosulfated polyethylene coated nylon, nylon infused with silicone and woven nylon.

3. The therapeutic heating sleeve as recited in claim 1 wherein said insulating batting material further comprises a non-flammable polyester material.

4. The therapeutic heating sleeve as recited in claim 1 wherein said insulating batting further comprises a thickness from 0.25 inches to 0.75 inches (6.35 cm to 1.9 cm).

5. The therapeutic heating sleeve as recited in claim 1 wherein said flexible resistance heating wire further comprises a nichrome wire with a thermoplastic sheath selected from the group consisting of vinyl, nylon and polyester.

6. The therapeutic heating sleeve as recited in claim 1 wherein said flexible resistance heating wire further having a diameter from 0.008 inches to 0.010 inches (0.2 mm to 0.25 mm).

7. The therapeutic heating sleeve as recited in claim 1 wherein said woven fabric interior lining further comprising a non-flammable cotton flannel material.

8. The therapeutic heating sleeve as recited in claim 1 wherein the length of the hook and loop fastener is attached by a method selected from the group consisting of sewing, bonding with adhesive and heat sealing.

9. The therapeutic heating sleeve as recited in claim 1 wherein said laminate pad is sewn together in a quilting fashion with stitching between the winding path of the heating wire to maintain the wire'"'"'s location and to provide structural integrity to the pad.

10. The therapeutic heating sleeve as recited in claim 1 wherein said electrical control is further comprised of a control module that is attached to the heating sleeve with a first flexible electrical cord.

11. The therapeutic heating sleeve as recited in claim 10 wherein said control module further comprises an on/off switch.

12. The therapeutic heating sleeve as recited in claim 11 wherein said control module further comprises a heat selection dial.

13. The therapeutic heating sleeve as recited in claim 12 wherein said control module further comprises temperature selection indicia that is located adjacent to said heat selection dial.

14. The therapeutic heating sleeve as recited in claim 10 wherein said control module further comprises a second flexible electrical cord that extends from said control module to an electrical plug.

15. The therapeutic heating sleeve as recited in claim 1 wherein said electrical control further comprise at least one high temperature thermostat within the flexible heating wire to automatically break continuity of the wire when the wire temperature exceeds a predetermined limit and to return continuity when the wire temperature attains a safe level.
