## Background
FIELD OF THE INVENTION
The present invention relates to a plurality of individually-controlled, combination heat/massage devices comprising pads with heating and massaging elements, which can be wrapped around body parts needing heat and massage therapy.
BACKGROUND OF THE INVENTION
It is well known to use heating pads for treating muscle and joint pain. It is also known that massage therapy can relax and soothe individuals. Several prior art devices combine heating/cooling elements with massage units. For example, U.S. Pat. No. 3,886,934 to Doty discloses a rigid housing with gripping arms for receiving a body portion, with a heating pad lining the gripping arms and housing, and vibrator means carried within the housing. U.S. Pat. No. 4,607,624 to Jefferson shows a unitary box-shaped device which contains a heating element, a vibration unit, and controls. U.S. Pat. No. 5,902,256 to Benaron discloses a flexible housing with one or more pockets for holding heating or cooling gel packs, as well as power vibrators. U.S. Pat. No. 6,193,678 to Brannon discloses a vest unit with a hook-and-pile-covered interior surface to which can be attached vibration units and heating elements.
However, none of the prior art devices combines the features of the present invention, which provides a plurality of heat/massage devices, each of which can be wrapped and secured around a different area of the body to relieve pain, swelling, and discomfort to knees, elbows, shoulders, ankles, etc. Several of the devices can be used simultaneously. Each device has individual controls to allow adjustment of the intensity of vibration and heat applied to an affected body part.
SUMMARY OF THE INVENTION
The heat/massage devices of the present invention can be generally rectangular in shape, or can be custom-cut to fit around a particular body part. Each device has a flexible water-resistant pad holding the heating and vibration elements; an optional soft inner layer and a protective outer layer can be used with the device. A releasable complementary fastening system is used to secure each device around a particular area of the user's body.
Each device is electrically and mechanically connectable to a control unit, either directly or in series with another device. As a result, a user may treat several areas of his or her body simultaneously. For instance, a body builder could treat both of his biceps and forearms simultaneously. Indicator switches on the control unit allow the user to adjust the heat level and vibration intensity of the elements in each pad. The control unit is generally powered using standard household receptacles; an adapter can facilitate its use with a vehicle's D/C power source.
The heat/massage devices can be made in different sizes, depending on the size of the user and the area to be treated. The appearance of the pads can be enhanced by the use of various colors and decorative designs.
It is an object of the present invention to provide a plurality of heat/massage devices to relieve pain, swelling, and discomfort in the knees, ankles, shoulders, elbows, and back by applying heat and vibration directly to several affected areas simultaneously.
A further object of the present invention is to provide heat/massage devices with individually controlled heating and vibration elements.
Yet another object of the present invention is to provide heating/massage devices which can be wrapped and secured around different parts of the body.
Still another object of the present invention is to provide lightweight heating/massage devices which are portable, versatile, and easy and convenient to use.
A still further object of the present invention is to provide heating/massage devices which can be connected in series, then connected to a main control unit.
