HEAT-MASSAGE DEVICE FOR PHYSICAL THERAPY BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combination heat massage unit that can be applied and affixed directly to the body portion being treated.

2. Description of the Prior Art Combination heating pad vibrator devices are well known in the prior art. However, none of the known such prior devices can be directly attached to the body part being treated and held there by the unit itself. Also none of such prior units are constructed so that the heating pad portion of the unit can be quickly and readily removed from and attached to the vibrator portion of the unit for cleaning and maintenance or for use of either the vibrator or heating pad portion of the unit apart from the other.

Examples of prior combination heating-massage units are shown in, for example, Ross US. Pat. No. 2,800,897, McElwee U.S. Pat. No. 2,850,009, ZiffU.S. Pat. No. 3,062,203, and Murphy US. Pat. No. 2,852,020.

In view of the foregoing, there is an apparent need for a combination heat-vibrator unit that is relatively portable and that can be readily affixed to various portions of the body. Such a unit would have particular utility for athletes and others participating in sporting events, such as baseball pitchers, football players, tennis players and the like, who could apply such a device to sore body parts during rest periods in the course of the game or match being played.

SUMMARY OF THE INVENTION In accordance with the present invention, a combination heating-massage unit is provided which is capable of being affixed and held to the body part being treated by the unit itself. Other features of the heat-massage unit of the invention are: light-weight construction, portability, easy operation, A.C. or battery operation, and easy separation of the vibrator and heating pad portions of the unit for cleaning, maintenance, or separate use.

The foregoing features are embodied in a heatmassage unit having a lightweight shell-type housing which carries the vibrator motor, the elecrical circuitry for operating the motor and the heating pad, and the necessary controls for the vibrator and heating pad. The unit is characterized by a pair of wide articulated arms. These arms extend from hinged connections at opposite ends of the shell housing which enable their outward swinging movement. Hinged elbows midway along the length of the arms enable inward hinging movement of the outer arm sections, whereby a body part can be inserted in the spacebetween the arms and the arms then wrapped about the body part to be treated. The pad itself is attached preferably by snapfasteners directly to the inner surfaces of the arms and housing, which together define a generally U-shaped structure when the arms are parallel to one another. In one preferred embodiment of the unit, the housing carries a battery pack and an electrical circuit that can ve switched so that the motor and heating pad can be perated either from an external A.C. source of electric power or from the self-contained D.C. battery source.

The foregoing and other objects, features and advantages of the present invention will become more apparent from the detailed description which follows, such description proceeding with reference to the accompanying drawing.

BRIEF DESCRIPTION OF THE DRAWING In the drawing,

FIG. 1 is a front elevational view of a heat-massage unit in accordance with the invention;

FIG. 2 is a side elevational view of the heat-massage unit of FIG. 1;

FIG. 3 is a top plan view of the heat-massage unit of FIGS. 1 and 2; and

FIG. 4 is an electrical circuit diagram of an electrical circuit suitable for use in operating and controlling the vibrator and heat elements of the invention.

DETAIALED DESCRIPTION With reference to the drawings, the heat-massage unit of the invention as shown in FIGS. 1, 2 and 3 includes a plastic, fibreglas, or thin metal shell housing 10 of generally rectangular shape. Such shell has a height just sufficient to carry within it an electrically-operated vibrator motor 11 and the electrical circuitry and controls necessary to operate such motor and an associated heating pad.

From opposite ends of the housing 10, a pair of articulated gripping

arms

12, 13 extend unidirectionally and normally at generally right angles to the housing. Thus the arms and housing together define an open-ended generally U-shaped space 14 therebetween into which a body part such as a shoulder, elbow, knee or the like can be inserted for treatment. From FIG. 2 it will be noted that each arm is of substantial width, the same width as the housing 10. Each arm is also preferably constructed of the same material as the housing. The housing and arms are sized, of course, so as to fit about the human body portions to which the unit is intended to be applied, such as the previously mentioned shoulder, elbow, arm, knee, neck or other body part. Each arm is divided into two parts including an

inner arm portion

12a, 13a hinged to the housing and an outer arm portion 12b, 13b, joined together at a hinged elbow 16.

A first hinging means comprising the piano hinge 18 connects the

inner arm portions

12a, 13a to the housing 10 in a manner enabling movement of the inner arms from their normally downwardly-extending positions shown in full lines in FIG. 1, outwardly through a substantial arc, such as 45, to the position shown in phantom lines with respect to inner arm portion 12a in FIG. 1.

A second hinging means comprising another piano hinge at the elbow l6 interconnects the inner and

outer arm portions

12a, 13a, 12b, 13b. Elbow hinges 16 enable movement of the outer arms from their normal positions in alignment with the inner arms as shown in solid lines in FIG. 1 inwardly to gripping positions through substantial arcs of, for example, 45 as shown in phantom lines with respect to outer arm 12b in FIG. 1. This articulated arm construction enables insertion of a body part into the space 14 between the opposed arms and then wrapping the opposed arms about the body part within the space to attach the entire heatmassage unit to the body part to be treated, where it remains until the treatment is completed.

An electrical heating pad 20, shown in FIG. 1, lines the inner surfaces of the arms and housing. It is removably attached to the arms and housing by mating snapfasteners 22 affixed to corresponding portions of the pad, arms and housing. This removable feature of the pad enables cleaning and maintenance of the pad and vibrator unit and also enables separate use of the pad and vibrator portion of the unit. Of course, if the pad is to be adapted for separate use, it is provided with a separate electrical cord or its own power source.

As has been mentioned, the heating pad may carry its own electrical cord for connection to an external electrical outlet. However, for compactness the pad preferably has an electrical plug 23 for direct plugging into an electrical receptacle 24 in the housing so that if an external power source is to be used, only one electrical cord, shown at 26, need be used. The cord 26 carries a plug at 27 which can be plugged into a receptacle 28 at one end of the housing as shown in FIG. 2.

The housing also carries suitable controls for controlling the operation of the heating pad and the vibrator motor including the on/off toggle switch 30 for the motor and the rheostat control 32 for controlling the heat output of the pad. Alternatively, a three or more position switch can be used in place of the rheostat control.

A further advantageous feature of the unit, which may be optional, is a self-contained source of electrical power provided by a battery pack within the housing. For such purpose, a third switch 34 is provided at the same end of the housing as the socket 28 for switching the operation of the unit from an external 1 10 volt A.C. source of electrical power to the self-contained D.C. battery source of power within the housing.

Referring to FIG. 4, a suitable electrical circuit, carried by the housing, is shown for operating the heatmassage unit on either its self-contained battery source of power or alternatively from an external source. Such circuit has two subcircuits, including a first subcircuit 36 leading from a source of external 110 volt A.C. electrical power, and a second subcircuit 38 leading from the battery source 40 of electrical power. The first subcircuit 36 includes a small step down transformer in the l 10 volt plug 27. Alternatively, a voltage dropping resistor could be used. The first subcircuit also includes a diode full wave rectifier 44 which converts the A.C. signal to a DC. signal. Leads from the rectifier 44 conduct the signal to the parallel motor circuit 46 and heating pad circuit 48. The battery subcircuit 38 includes leads which intercept the leads from the rectifier for transmission of DC. power from the battery pack to the motor and heat circuits when the selector switch 34 is properly positioned.
