Russo, Norristown, Pa. (RG. Box 62, Rte. 113, Creamery, Pa.) Filed Nov. 12, 1963, Ser. No. 322,810 19 Claims. (Cl. 12d-57) This invention relates to an improvement on applicant prior Patent No. 2,889,826 of June 9, 1959 for a Massage Machine.

A further object of this invention is to provide a rnessage roller assembly `for such massage machine whereby the -massage rollers may be readily adjusted to lit the contour of a pers-ons back so as to better exercise the back muscles and stimulate the blood circulation.

Still a further object of this invention is to provide an adjustable massage rol-ler assembly which can -be adjusted for spot massage, whether a small spot, by a single massage roller, `or a larger spot, by using two or more adjacent rollers, or two or more different spots, of any size, by using spaced apart individual or spaced apart groups of single or adjacent massage rollers.

With the above and related objects in View, this invention consists in the details of construction and com-bination of parts, as will be more fully understood from the following description, when `read in conjunction with the accompanying drawings, in which:

FIG. 1 is an end elevational view, partly in section and partly in elevation, of the massage machine to which this invention has been applied.

FIG. 2 is a -front elevational view of the massage actuating mechanism of FIG. l.

FIG. 3 is a sectional view on an enlarged scale on line 3-3 of FIG. 2, showing the adjustable rubber massage rollers.

FIG. 4 is a front elevational view of one massage roller.

FIG. 5 is a sectional View on line 5-5 of FIG 8, showing one of the massage roller latching elements.

FIG. 6 is an enlarged front elevational view of the massage roller assembly.

FIG. 7 is a top elevational view of FIG. 6.

FIG. 8 is a view similar to FIG. 6, but with the individua-l massage rollers adjusted to the contour of a human back.

FIG. 9 is a Itop elevational view of FIG. 8.

FIG. 10 is a fragmentary perspective reversed View of one end o-f the slidable latching bar.

There is shown at 1t) the massage roller assembly of this invention. For purposes of illustration, the massage roller assembly 10 is illustrated as being used on the massage machine of applicants aforementioned Patent No. 2,889,826, but of course this invention may be used on any suitable massage machine intended for the same general purpose. The plurality of spaced apart upright arms 12 which support the massage roller assembly 10, there being one assembly 1U* on each of the plurality of arms 12, correspond to the plurality of spaced upright arms `53 of the prior patent mentioned, and the remaining details of the massage machine illustrated are identical in construction and operation with the corresponding details and construction shown in this prior patent, `massage roller assembly 10 of this invention taking the place of the axles 66 and 7G and the massage rubber r-ollers 68 and 72 therein described.

In brief, the pairs of arms 12 are supported on the wheels 14 and follow the paths shown by the arrows 16 on the tracks 18, such action lbeing caused by the electric motor 20, belt 22 and pulley 24 mounted on the mechanism generally shown at 26 and adjustably supported by the mechanism support fork 28 on the stand 30 over the massage table 32. The mechanism 26 also includes a wheel 34 on straight track 36 supporting upright mounting arms 38 on which are ixedly secured transverse support arms 40. The arms 41B are actuated by the offset end 42 of 4a rotatable driver rod 4M and this motion is, in turn, transmitted to the pairs of upright arms 12 by the ends 46 of the rods 48 moving `in vertical slots 50 in the arms 12. The construction and operation of the details just described, except for the massage roller assembly 10 in place of the massage rollers shown in the prior patent mentioned, being identical with that of such patent; the details Kof construction and operation disclosed in such patent are incorporated herein Iby references, and hence not further repeated herein.

The massage roller assembly 11i comprises a plurality of individual rub'ber massage rollers `52, each roller 52 being journaled on yan individual horizontal axle 54 of an individual fork 74, so that the position of the individual fork 74 will, of course, determine the position of the particular massage roller 52 journaled on its axle 54.

Each fork is individually adjustably supported by means shown in detail in FIGS. 3 and 5 to 9 inclusive. Such means include one transversely extending bar 76 rigidly secured to the three arms 12 on one side of the forks 7d, a second transverse bar 114 rigidly mounted on the opposite side of the three upright arms 12, yand bar 78 therebelow slidably mounted through yokes 80 secured on the arms 12. Pins 82 extend through the top and bottom of the yoke 8i) at least at one end into slots 841 of limited length in the top rand bottom of the slidable bar 78, limiting the sliding movement of the bar 78 in one direction, and a stop finger 86 secured by stud screws S8 to the end of bar 78 beyond its yoke 8@ limits its sliding movement in the opposite direction..

The opposite end of bar 73 is bifurcated at 90 and has a pawl 92 pivoted between the bifurcation and biased downwardly by a spring 94 biased against a handle button 96 which urges said pawl into latching position with the inner side of th-t adjacent yoke 80, as shown in FIGS. 8 and 9. When the pawl 92 is pivoted to unlatching position, shown in FIGS. 6 and 7, com-pressing biasing spring 94, another spring 9S, biased between projections 101B on the bar 78 and the adjacent side of both the adjacent support arms 12 and the yoke 80, biases the bar 78 in one direction to the limit permitted by the stop linger 86 at the other end, the sliding movement of the bar 78 in the other direction being limited by the slots 84 cooperating with pins 82 when the pawl 92 is in latched position.

The inner side of the `slidable bar 78, that :faces against the spaced apart forks 74, is provided `with spaced apart vertically extending ri-bs 102, `corresponding in number With the forks 74. The ribs 102 define channels 104 therebetween. The rigid bar 76 is also provided with correspondingly spaced ribs 106 defining channel 10S therebetween. Each fork 74 has vertically extending ribs 110 and 112 on the two opposite sides facing the rigid transverse bar 76 on one side and the slidable transverse bar 78 and rigid transverse bar 114 on the other side, the fork ribs 111i facing the rigid bar 76 being complementary to the channels 108.

Above the slidably mounted bar 78, the transverse bar 11d is rigidly secured to the arms 12 by stud screws 116. This second rigid bar 114 is provided with vertical ribs 118 defining channels 120 complementary to the fork ribs 112. As far .as the fork ribs 111i and 112 and the complementary channels 120 in bar 114i and channels 108 in rigid -bar 78 is concerned, the forks 74 therebetween may be moved freely in either vertical direction. Such vertical direction is limited and further guided by a rod 122 secured to the arms 12 and extending through vertical slots 124 in each fork 74, with an individual coil spring 126 biased between the bottom of the rigid rod 122 and the bottom wall 128 of each fork slot 124, thus urging each fork downwardly.

Each vertical rib 102 on the slidable bar 78 is serrated into transverse flutes 130, and the facing fork rib 110 is likewise serrated into complementary transverse flutes 132. When the pawl 92 is in the unlatched position shown in FIG. 6 and FIG. 7, the complementary flutes 130 on slidable bar 78 are in engagement with the complementary utes 132 on the fork ribs 111D, thus holding the forks against vertical movement. When the pawl 92 is in the latched position shown in FIGS. 8 and 9, the flutes 131i on the ribs 102 of slidable bar 7S have been moved out of engagement with the complementary llutes 132 on the fork ribs 110 and extend into the space between the fork ribs 110, and the forks 74 may move vertically, 4being biased downwardly by the springs 126. When a person is lying on the massage table 32 with the roller assembly adjusted by the stand 30 into contact with his back 134, the massage rollers 52 carried by the forks 74 will be individually biased downwardly by springs 132 into contour contact with his back 134 as shown in FIG. 8. Obviously, both sets of roller assemblies 10 shown in FIG. 1 will be successively thus adjusted into contour contact, and provide for contour massage of his entire back 134.

Should selected spot message be desired, then as many selected masasge rollers may be held in lifted position out of back massaging position by lifting the selected individual forks until an aperture 136 in the fork'rib 110 is engaged by a retractable plunger 138 urged therein by a spring 1411, the top of the rib 110 being curved at 142. The plunger 138 is `biased by the spring 140 located in a cylinder 144 threaded into the fork rib 1111 and biased between a pin 146 transversely through the plunger 138 and a plunger handle 148.

1n operation, the person having his back 134 inassaged lies on the table, 32, and the stand 3@ is adjusted to bring one of the roller assemblies 10 into contact with his back 134. The assembly 10 in contact is then brought into contour contact by an operator person pushing inwardly the slidable bar handle button 96, thus sliding bar 78 to the limit permitted by slots 84 and pins 82 while pawl 92 is biased to the latching position shown in FIG. S and FIG. 9 by spring 94. If spot massage is desired instead of complete contour massage, then as many selected massage rollers 52 may be disengaged as desired, by pushing the selected massage rollers 52 upwardly, against the bias of their springs 128, until the curved top 142 of the fork rib 110 rides upwardly against the end of the plunger 138 which is biased into aperture 136 by its spring 140 when in aligned position, thus holding the selected rollers 52 in disengaged position.

The pawl 92 is then unlatched, permitting the bar 73 to be slid by its bias spring 98 until stop linger Sil abuts its adjacent support arm 12. As it moves to this position, the slidable bar rib flutes 130 move into position complementary to the fork rib flutes 132, which may yield slightly up or down as necessary for engagement purposes, and the roller assembly is thus locked in the contour position. Then the other roller assembly is brought into back contacting position, and suitably adjusted in a similar manner. Thereafter, the motor is actuated to provide the desired massage operation, as fully set forth in the aforementioned patent.
