Application August 9, 1954, Serial No. 448,451

Claims. (Cl. 128-243) This invention relates to massage devices and in particular to improved applicator massage devices.

The primary object of the invention is to provide a universal massage device for both cold and heated roller applications and for still heat application constructed and formed for use on both extremely sensitive and non-sensitive body areas or at local diflicult-to-contact spots wherever mechanical or heat therapy is called for, and which is employable to carry and apply medicament to any portion of the body during massage, or to massage portions of the body with or without medicament having eeen applied thereto.

A further object of the invention is to provide a roller type massage device adapted for use dry or to apply medicaments or for use with applied medicaments comprising a hand grip and a cylindrical conically pointed massage head rotatably mounted thereon, the said massage head being adapted to receive and removably retain thereon an applicator covering which serves to spread and massage in medicaments already applied, to receive, hold and apply medicaments, and to cushion the massage head when rolled over or applied to injured or tender portions of the body; the said massage device including a nonrotatable heating element which provides uniform heat during roller massaging or spot heat of various intensities at one side of the roller when the massage head is held against a portion of the body without rolling-the intensity and location of the spot heat depending upon the orientation of the hand grip after the applicator head is placed against the body.

Other objects of the invention will become apparent by reference to the following detailed description taken in connection with the accompanying drawing, in which:

Fig. 1 is an elevational view of a massage device embodying the invention.

Fig. 2 is a vertical sectional view through the massage device.

Fig. 3 is an enlarged fragmentary sectional view showing one type of heating element that may be employed.

Fig. 4 is a sectional view taken on the line 44 of Fig. 2.

Fig. 5 is a more or less diagrammatic sectional view taken on the line 55 of Fig. 2 showing the thermostatic switch and heating element and electrical connections thereto.

Fig. 6 is a cross sectional view taken on the line 66 of Fig. 2.

Fig. 7 is a wiring diagram.

Fig. 8 is a fragmentary view showing the use of a reticulated cushion element for soft massage and to retain excess medicament.

Referring now to the drawing wherein like numerals refer to like and corresponding parts throughout the several views, the particular embodiment of the invention disclosed for illustrative purposes comprises a cylindrical sonically pointed roller element 19 rotatably mounted on a tubular spindle 11 fixed in a hand grip 12. The hand grip 12 is bored at 13 to accommodate an electric cord 14 and counterbored at 15 to receive the spindle 1. T he lower end of the hand grip 12 is also counter-bored 16 to receive a ferrule 17 through which the electric cord 14 extends. The ferrule 17 accommodates a strain relief clamp 18 which is clamped to the electric cord 14 to prevent it from being pulled out of or pushed too far into the hand grip 12.

An annular Washer 19 is telescoped over the tubular spindle 11 and is secured to the inner annular end of the hand grip 12 by such suitable means as the countersink head screw 20. A collar 21 is also telescoped over the spindle 11 with the bottom of the radially outstanding flange 210 thereof positioned in abutment with the top of the annular washer 19, and the said collar 21 is fixed to the spindle 11 by such means as a set screw 22. A name plate 23 is secured onto the bottom of the washer 19 by suitable studs 24- extending therethrough into the outstanding flange of the collar 21.

The annular washer 19 and name plate 2-3 are apertured to accommodate a reflector jewel 25, and the flange 21% of the collar 21 is apertured opposite the jewel to per mit light from the heating element 26 to reflect through the jewel 25 for the purposes hereinafter described. The heating element 26 is preferably composed of a suitable number of turns of resistance wire formed into a coil disposed in continuous reverse bends through arcuate mica or other insulating supporting bars 27 held in spaced relationship to each other and the outstanding flange 210 of the collar 21 by

sleeves

28 and 29. The arcuate mica bars 27 maintain the heating element 26 in uniform spaced relationship to roller element 10. Screws 3% extending through the mica bars 27 and

sleeves

28 and 29 are threaded into the outstanding flange of the collar to fix the mica heating element insulating and supporting bars 27 and resistance coils 26 carried thereby into spaced relationship to the other adjacent and surrounding elements of the massage device.

As best shown in Figs. 2, 5 and 7, electric current from a suitable source S flows through the resistance coil or heating element 26 and an adjustable thermostatic circuit breaker 31 which breaks the flow of current to the heating element 26 when a selected Warm or Hot temperature is attained thereby, the adjustment of the thermostat by the control knob 32 determining the temperature at which the heating element 26 is cut out by the thermostatic circuit breaker 31. Thus, the temperature to which the heating element 26 may heat the roller element is c r.- stantly governed by the setting of the thermostatic circuit breaker 31.

The roller element 10 is preferably cast or otherwise formed to the cylindrical conically pointed shape shown in Fig. 2, is centrally bored at 33 to rotatably on the outer end of the spindle 11, and is provided with a pair inwardly extending diametrically spaced arms 34 onto the inner ends of which an apertured bridge 35 is secured by means of studs 36. The apertured bridge 35 neatly fits the spindle 11 for the purpose of permitting the roller element 10 to rotate on the spindle 11 substantially without wobble. To prevent the roller element It? from sliding axially from the spindle 11, a circularly formed re tainer angle 37 is riveted or otherwise secured to the inner periphery cylindrical portion thereof as best shown in Figs. 2, 3 and 8. The annular inwardly disposed leg or retainer ring 37% of the circular retainer angle 37 overlays the radial flange 210 of the collar 21 fixed to the spindle it to prevent the roller element from axially sliding off the spindle ll; however, adequate working clearance is provided between the retainer ring 370 of the retainer angle 37 and the flange 210 of the collar 21 to permit the roller element 11 to rotate freely at all times Over the roller element 11 is disposed a close fitting fabric cover 38 which has its lower end or skirt 380 folded upwardly adjacent the retainer angle 37 and is held in such position by means of a split spring retainer ring 3?) having finger grips 390 formed at the split therein to permit the said retainer ring 39 to be readily positioned to hold the fabric cover 38 in place. This fabric cover 38 is preferably formed of a relatively soft absorbent material to carry medicament if desired or to aid in the spreading of medicament previously applied to the portion of the body being massaged.

Fig. 8 discloses the use of an apertured or reticulated cushioning element 40 of soft rubber, sponge rubber or other material which fits snugly over the cylindrical conically pointed roller element 10. The thickness of the cushioning element 49 and the size and spacing of the apertures ill therein may be varied to suit the purpose for which the massage device is employed. The massage device may be used with or without a cushioning element, but, when a cushioning element having rather small apertures 41 is employed, the apertures 41 will serve as retainers for medicament applied to the cover 38 thereover. When the cushioning element 41 is used alone, it fits sufficiently snugly onto the roller element 10 so that it retains itself thereon.

It is obvious that the improved massage device embodying the invention has many uses, and its cylindrical pointed roller element 10 is considered to be substantially universal in its application to the various parts of the anatomy. It should be noted that the massage device may be used with or without the fabric cover 38, with or without a cushioning element 41, and with or without the application of heat. Of considerable importance is the thermostatic heat regulation and the spot heat available to the user. For example, if the th rmostatic element of the circuit breaker 331 is of the range of from 110 to 120 degrees, the heating element 26 and thermostatic element will operate to maintain the massage roller element ll within that temperature range as determined by the setting of the thermostat control knob 32. user would like to have a hot spot heat for application to a particular muscle, joint or the like, the massage device is held on the selected body area or point without rotation of the roller element 10 with the jeweled indicator disposed nearest the selected area or point of heat application. Conversely, a relatively cooler spot heat is obtainable by holding the massage device against a selected body area or point with the portion of the roller element Trill opposite the jeweled indicator disposed nearest the selected area or point of heat application. The thickness of the fabric cover 38 and/ or the thickness and type of cushioning element 49 give added versatility in the use of the massage device embodying the invention.

Although but a single embodiment of the invention has been disclosed and described herein, it is obvious that many changes may be made in the size, shape, arrangement and detail of the several elements of the invention, all without departing from the spirit and scope thereof as defined by the appended claims.
