ApplicationJuly18, 1946, Serial No. 684,425

This invention relates to improvements in massaging rollers.

One of the objects thereof is to provide asimple, efiicient, and inexpensive massaging roller for the purpose of efiecting a better kneading action of the roller upon the tissues of the body over which it is used.

Various devices have been manufactured in the field of massage rollers and many of them have been fabricated with a view of affording increased bearing or rolling surface, more powerful massaging action, and capability of flexing out of the linear disposition over protruding portions of the human anatomy. However, previous efiorts have not resulted in providing a massage roller. with an equalizing resilient action on allpoints of the roller where such action is desired.

The characteristics of the present massage roller are such that the roller is made to have an eccentric movement or rolling action with respect to the shaft which constitutes its aXis of rotation,. such eccentric rolling action being spring cushioned.

Another object of the'present invention is to provide a massaging roller characterized by the fact that it is normally mounted concentrically upon an operating shaft which carries two han-.

dles for rolling it at opposite ends thereof. The

massaging roller, however, is journaled upon the operating shaft through intervention of circular resilient bodies which act as yieldable cushions therefor.

A further object of this invention is to provide a novel form of massaging roller which may not only be rolled upon the part to be massaged but spring tension followed by resiliently jumping back or retracting itself. This has a correspond ingly wholesome effect in that the tissue thus kneaded responds to alternate pressure and. relaxation. It is this which stimulates proper blood 16 Claims. (01.- 128-57) parts which are directly subject to spring tension and resilient manipulation. The roller proper is a stout, strong rubberlined body but the handle shaft for revolving it has a floating sprong hearing inside of the roller so while the roller turns the handle may be moved yieldably to resiliently press the roller against the surface being massaged and to relax pressure thereupon alternately. V With'the above and other objects in View my invention consists in thecombination, arrange! ment and details. of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims,

In the drawings, wherein similar reference characters designate similar parts throughout the respective views, T

Figure 5 is a cross section taken through my invention shown in Figure 1, illustrating how the circular sprin is housed, and.

Figure 6 is a planview of the massaging roller.

Referring to the drawings, which are-merely illustrative" of my invention, all the details thereof are made to appear. The figure Ill desig nates a hollow cylinder roller or cylinder, preferably a metal or plastic shell, the hollow interior of which is designated H. 'A series of similarly constructed cages are employed in this roller cylinder, broadly designated l2. 'The spool therein will first be described. v

Each spool is made'preferably' out of plasti one: end of the hub. That portion of the hub which projects beyond "the nearest flange i1 is" designated 24. The device is a strong, substan-- tial body. v

In Figurei is illustrated the cage proper. It may also be made from plastic, metal or other suitable material. The cage consists of two telescopically interfitted cap members, the rims of the respectively outer and inner of which are designated- 29, 23, while the opposing sidesof these caps, which are parallel, are designated 18 and H. 11: will be seenthat the

rims

20, 23 of Upon the the telescoping cap members register slidably if desired. Together they provide an annular closed body, or casing, with centrally aligning large openings i5 and 22 formed in the respective sides i8 and ii of the cap members. The hollow interior of this casing is denoted at Ma.

A series of these cages is employed in the hollow massaging roller as shown. Before the cap members composing same are placed into interfitted closed relationship as shown in Figure 4 it is designed to insert the spools shown in Figure 2 into them. The spool is inserted into the single cap member first and enclosed in the cage by the action of the other cap member, telescoping over the first cap member. In this manner the spools are removably assembled in the cages.

I design to use a circular or cylindrical resilient unit in each cage. Same is preferably made from a coil spring but could be fabricated of other material such as solid rubber, just as well.

Each circular resilient member consists of a circumferentially extending radially disposed successive series of spring convolutions or cylindrical yieldable coils which stand spoke-like in circular order like a wheel, as is clearlyshown in Figure 5. This produces a peripheral head surface of large outer diameter 35 and a constriated inside central reduced diameter forming a central bearing surface 38.

Each .of these circular springs is caused to frictionally embrace and be seated upon the hub 24 of a spool so that opposite sides of the several coils 36 abut the flanges l6 and I! of the spool while the outer circumference of the circular resilient member engage the inner surface of rim 20 of one of the cage cap members 18. The hub of the spool thus passes through the central open ing or bearing surface 38 of the spring body.

An elongated shaft 25 extends the full length of the cylindrical roller 10, being formed at onposite ends with reduced

stubs

21 and 28. The stubs provide

annular shoulders

26 and 28 with the

stubs

21 and 29, respectively. Tubular handles '29 and 30a respectively fit rotatingly upon the shaftstubs 2! and 29. In one direction these handles are confined in place on the stubs by the annular shoulders 25, 2B. In an opposite direction they are held against displacement from the stub by means of screws '30 which are threaded into the ends of the shaft 25 and have heads 3! overlying both these flat shaft ends and the

handles

29a, 30a each.

The cages are set at properly spaced apart points inside of the bore H of the cylinder I0, so their circular surfaces engage and may be cemented and secured together optionally. Two

of the cages are mounted in the opposite ends of the cylinder in such a manner that they effectively close these ends of the cylinder. Thus the sides l8 and 2| of the :cap members of these particular cages serve as the closure members. The flanges of the spools may slide eccentrically against sides l8, ill of each cage. This is what will take place when the circular springs, seated in the circular channel 13a of the spools, are compressed by pressing the shaft 25 against these springs in the act of imparting rotation to the massaging roller.

From the foregoing it will readily be seen that the circular springs properly center the shaft 25 and hubs l3 of all of the spools in the openings 19, 22 of each separate cageso that the shaft 25 may eccentrically float in these openings. Before pressure is imparted to the roller H! shaft 25 is concentrically disposed in roller l0. By taking hold of handles 29:; and 30a of the shaft and rolling the roller Ill over the human body,

and exerting pressure on the roller, the pressure is assumed directly by the circular springs, thus minimizing the feeling of hardness of a solid roll and obtaining a smoother more efficacious pressure and relaxation thrust of the massaging roller. The outer surface of the roller is covered by a rubber sleeve composed of a longitudinal series of hollow rubber annular bodies 3| with intervening annular grooves 32. These parts furnish additional softness and yieldable tread to the roller and enhance the massaging action thereof. The stems 24 of the hubs of the spools are secured by fasteners 23 to the shaft 25 and confine the cage in place by confining the spools themselves.
