9 =Claims. (Cl. 128-33) The present invention relates to a massage table,

particularly a massage table providing body supporting parts and applicators, all .of which are power driven.

:Certain objectives heretofore suggested in nassage treatment consist of vibrating a table or ,a couch upon which the patient reposes, applying localized massage to selected portions .of the body of that patint,.;and manipu- Latina his legs w a omp und motion eft ctin niaterially all of the leg muscles at one phase or another during the motion, ith ,all driving power for suchmo ion being supplied from external sources. However, no one has, prior to our invention, suggested that all of these objectives could be accomplished from a single, power operated massage table upon which the patient can remain for the entire sequence of treatment. Past apparatus embodying separate units for each operation required that the patient be disturbed from time to time I in being removed and transferred from one unit to the next for successive operations.

The consolidated massage table structure according to this invention includes a vibrating top .or table .portion having 'body applicators and additional mechanism for exercising the legs. More specifically, the massage table has a stationary bed or frame constituting the table supporting structure, a reciprocating table top secured thereto on bodies forming vibration mountings, a pair of pads slidably mounted in longitudinaily formed openings in the table top to reciproeate'lengthwise of the table substantially in the plane ot those openings, :1 pair of foot supports rotatably mounted above one, end of the table supporting structure to manipulate the ,feet and legs of a reclining patient with compound motion and first, second, and third electric motors disposed at different points in the table supporting structure which have separate drives to the table top, pads, and {the i 91 sup ports.

More particularly, the electric motor drive to reciprocate the table top includes an idler sheave spaced from the first motor, an unbalanced weight device connected to reciprocate the table when the weight is rotated; and "V-belts continuously interconnecting the motor and the unbalanced weight device through the idler sheave.

The separate motor drive to reciprocate the pair of body pads includes an eccentric, eccentric shaft, crank, and a connecting rod driven by the second motor, rollers and roller ways to carry the individual applicator pads which reciprocate on the ways and which have individual drive links at one end of each pad, and a rocking fork mechanism providing a split drive between the connecting rod and the drive link for each applicator pad; The rocking fOIi mechanism carries a spaced pair of rigid pins which are rocked thereby about their midport-ions and whichcarry slide :b'locks pivoted to the pad drive links and slidable verticallyto-adjusted positions on the length of the pins. A parallelogram linkage for supportingeach slide :block includes a hand lever which controls the in dividual elevation of the slide block for setting the stroke phase- Patented Jan. 14, 1958 ice of the associated pad and which also selectively controls Whether the padoscillates-in direct or opposite phase to the other pad, depending on whether the slide block-is set at a point above or below the neutral midportion on the pin along, which gitslides. This second motor which drives the applicator pa s is run continuously and the applicator motion is individually stopped or run by app op t op a ion of the parallelogram .stroke setting linkages to giye the appliator pads the same .or difierent strokes both with respiqc Io'stnoike length and to stroke The separate motor drive to move the toot supports includes a PQ-i wQf spaced yettiual shafts geared tthlIOUg-h separate d i e conne ti ns o the third motor, a crank 'atm c qtendinghpm the s ipper end ;.of .each'vertical s'hafit andqhaving to diagon lly outwardly extending socket in the outer end thereof-,mndf a foot support .jour naled in spa ed hea n s o tained in thatsocket sothat they will not rot-ate about eir own axes as the crank arms ,reol e a out t e v rtical shafts.

Attire upper 1end, -the rectangular framework supports a un tary table top 1 6 having a rectangular metal" frame i' ?Y a p ced-pair of longitudinally extending side ra ls: l8, o ned-at their opposite. ends by meansof' a first pair of cross ails ,20: andv further joined by a second pair of cross rails. 22 intermediate the' 'first' rails, and also by a ser esof .thpee .centen- sectionrails 24, 26, and28 The center-section rail 24':isconnected by means of a pair of anger bans -3o"withtth! adjacent one-of the second pair of ra ls 22 and the 2tl is-zfuitherconnected to the ad Jaeent cen ertSlcC iolr rail 26: by: means of a spaced pair of railsfiz. At: thczfiourcorners thereof, the table toplb s securedto thcupflg'ht framework by means of a' set of deforrnablebodies .forming vibration mountings 34*. fheumtary table top l6= carries a plywood foundation panel .36.hav.1ng; openings therein generally corresponding t therectangular openings defined, between the rails 18; 24, 2 6,and32 whichreceivetherein a pair oflbody appli cator pads 38 and 40. Each: of these'pads-is in the form of a. pad 42 9f foam rubber or the like covered by the usual upholstery cloth which is preferably waterproofand formed in a pad 44 carried by the plywood foundation panel 36.

A first electric motor 46 is mounted at one end of the table framework and has a V-belt drive connection to an idler sheave diagrammatically indicated at 48. A cantilever beam 59 is pivoted at one end to the table supporting framework and carries the idler sheave 48 at its outer end in order that, under the influence of gravity, it

maintains tension on a V-belt 52 which is trained with its lower end about the idler sheave 48. The V-belt 52 drives a shaft 54 through a sheave 56 fast to one end thereof. The shaft 54 is rotatably mounted at its opposite ends in a set of bearings 58 carried by the hanger bars and at its midportion the shaft 54 has an unbalanced weight 60 bolted thereto so as to produce a vibratory motion of unbalance when it is rotated.

A second electric motor 62 is mounted to a center platform in the table supporting framework and is belt connected through an intermediate sheave 64 to a sheave 66. The sheave 66 is carried at the end of a driven shaft 68 which is rotatably mounted in a set of depending bearings 70 secured to the respective beams of a frame 72. The frame 72 has a pivot bar 74 at one end pivotally securing it to a pair of brackets 75 depending from the upright framework. At the opposite end, the frame 72 has an adjustable wing nut connection 76 to a cross rail 77 afiixed to the upright framework so as to vary the tension in the connecting belt between the sheaves 64, 66. The pivot bar 74 provides a fixed swing axis facilitating this tension adjustment. A pair of diagonal braces 78 rigidities the connection at one end of the table between the upper side rails 14 of the framework and the pair of adjacent table legs 10. These latter legs 10 have an upright frame bolted thereto which carries a foot support mechanism generally indicated at 82. Each of said foot supports 84 includes a heel rest 86 for supporting the foot of a patient reclining on the unitary table surface defined by the pad 44 on the table top 16. The end of this unitary table surface and table top 16 is foreshortened at 79 and the supporting framework extends therebeyond to give clearance to the frame 80 for the mechanism 82. At the opposite end, there is a hand rail 81 extending across the central portion of the table and having U-shaped side pieces which extend around and under the end of the table. The lower portion of these side pieces extends into sleeves 83 secured to the main frame.

The driven sheave 66 is suitably connected through the shaft 68 and suitable mechanism 88 to the individual body pads 38, 40 so as to reciprocate them in the plane of the rectangular openings in the table. The electric motors 46, 62 plus a third electric motor 90 in the foot support mechanism 82 are controlled from the respective upper, middle, and lower buttons in a push type switch box 92 which is energized from a plug-in type electric cord 94 carried by the table framework.

As best seen in Figures 3 and 4, the driven shaft 68 which carries the sheave 66 at one end also carries an eccentric 96 fast thereto and fitting into one end of a connecting rod 98. The connecting rod 98 is connected at the opposite end to a depending; crank 100 which is fast to a cross shaft 102 forming a driving member of the mechanism 88 to operate the pads 38 and 40 with an adjustable stroke. The driving member shaft 102 carries the crank 100 so as to depend from a midportion thereof and at spaced points from this midportion the shaft is journaled to rotate in a pair of bearings 104 which depend from the pivoted frame 72. At its outer extremities, the driving member shaft 102 carries a pair of outwardly directed. forks 106 which support individual vertically disposed rocking pins 108 bridging across the forks and secured thereto by means of a set of nuts 110. An apertured slide block 112 mounted to each of the rocking pins 188 has a pivotal connection to a pair of applicator pad drive link 116 or 118 as appropriate. The one drive link 116 is pivotally joined at 120 to the body applicator pad 38 and the other drive link 118 is pivotally joined at 122 to the remaining applicator pad 40 which is substantially transversely aligned with the applicator pad 38. Each pair of the end plates 114 at its rear extremity is pivotally connected to a different elevating link 124, which links are separately carried in spaced relationship by means of respective parallelogram type stroke setting linkages 126 and 128. The parallelogram stroke setting linkages 126 and 128 each include driven links 130 and 132 which pivotally support the individual links 124 and which are rotatably received to rock upon a fixed cross shaft 134 carried in spaced apart bearings 136 mounted to the lower side rails 14 of the table supporting framework. A pair of adjacent hand levers 138 and 140 have individual fixed quadrants 142 upon which they are adjusted and locked by means of a j'set of detents 144 so as to raise and lower the drive links 116, 118 by means of the parallelogram linkages to adjust the stroke of the body applicator panels 38 and 40.

Figures 5 and 6 show the slide block and stroke setting mechanisms for the pad drive links 116, 118 in detail. The forks 106 have hubs 146 received on the common driving shaft 102 and they are each made fast to this shaft by means of a cross pin 148. Each of the slide blocks 112 carries a pair of outwardly extending trunnions 150 to which the spaced end plates 114 of the drive rods 116, 118 are secured. These end plates 114 carry ,a pivot pin 152 connected to the upper ends of the respective elevating links 124. The lower ends of the elevating links 124 carry a pivot pin 154 which is mounted to each of the driven links 130 and 132 at a point spaced from another pivot 156 connecting that link with its respective parallelogram linkages 126 and 128. The driving links and 157 for the parallelogram linkages are mounted to corresponding ends of the telescoped inner and outer shafts 160 and 158. The inner shaft 160 extends through bearings, not shown, mounted to the diagonal braces 78 in the table supporting framework. At their outer ends, the shaft 158, 160 carry the respective hand levers 140 and 138 and by independently rotating and locking these hand levers an operator is able to adjust the corresponding parallelogram linkage 126 or 128 .to change the stroke setting on the body applicator panels.

Figure 7 shows the body applicator pad 38 which is typical for both pads 38, 40. The pad 38 is essentially a wooden plate assembly bolted together at 162 and consisting of an upper plate 164, a lower plate 166 and a narrow spacer plate 168. Sheets 170 are clamped between these plates and extend beyond the sides of the narrow spacer plate 168 to define roller channels 172. The metal rails 18 and 32 adjacent the channels 172 carry rails 174 each of which presents a row of fixed studs 176. Each stud 176 carries a spherical bearing portion 178 at the head end and adjacent the head carries a roller wheel 180 received in the channel 172 so as to roll on the sheets 170. In one physically constructed embodiment of the invention, the spherical bearing portion 178 at the head had a two-inch radius of curvature where it engaged the spacer plate 168 and the roller wheels 180 were ball bearing type roller skate wheels. In brief reference to the foregoing Figure 3, it can be noted that the roller wheels 180 are provided three to a side for each of the body applicator pads 38 and 40 and that a pair of spaced straps 182 secured to the bottom of the bolts 162 have bent ends carrying the respective pivots 120 connected to the panel drive links 116.

Figure 8 shows a transverse cross section through the table vibration mountings 34 which are elongated bodies of rubber, elastic plastic, or similarly deformable solid materials. The deformable bodies are bonded at the bottom to a channel shaped mounting member 184 which is bolted at 186 to a structural bridging member 188 of angle spaced end plates'114 together carried at the end of an 75 cross section. This bridging member 188 is welded at 190 at its opposite ends to the upper side rails 14 of the table supporting framework. Along the upper face thereof, the deformable bodies in the vibration-mountings 34 are bonded to a partially embedded U-shaped channel member 192 which is deflected at its opposite ends to receive abolt 194 carried by the adjacent table top cross rail 22. The table top cross rail 22 has welds 196 at its opposite ends securing it between the table top side rails 18. Being disposed so as to extend generally transversely to the unitary table top 16, the deformable bodies in the vibration mountings 34 are relatively stifi against lateral movement of the table top and they act generally as narrow shear pads in the longitudinal direction of the table so that it readily is vibrated lengthwise with a patient reclining thereon.

In Figure 9, the foot support mechanism generally indicated at 82 includes a pair of spaced vertical drive shafts 198 mounted adjacent their upper ends in a set of bearings 200 carried by and disposed outboard of the foot support frame 80. At their lower ends, these outboard drive shafts 198 are connected through worm type reduction gear boxes 202 to a common shaft 204 driving the same. The third mentioned electric motor 90 drives the shaft 204 through a sheave and V-belt drive indicated at 206. At its upper extremity, each vertical drive shaft 198 is connected to a different one of the foot supports 84 in the same manner. A generally rectangular radius bar 208 formed from a block of hardened aluminum or light metal material is made fast to the extremity of the appropriate shaft 198 such that its outer end describes a horizontal path of swinging motion as the shaft 198 rotates.

The reduction gearing in the gear boxes 202 is such that these shafts rotate in opposite directions from one another so that the radius bars 208 rotate in opposite directions but symmetrically to one another. At the swinging outer end each radius bar 208 has a deep socket 210 which extends diagonally upwardly and outwardly and receives a pair of spaced ball bearings 212. The ball bearings 212 are captive in spaced relation upon a shaft 214 carrying the foot support or applicator 84 and the lower ball bearing 212 rests on a bottom shoulder within the deep socket 210. Each one of two spaced brackets 216 has a set of three screw connections to the respective shaft 214 and applicator 84 to hold them rigidly together and the center connection of each set comprises a set screw for effecting up and down adjustment of the applicator 84.

In operation of the massage table of Figures 1 through 9 foregoing, a patient is placed on the pad 44 carried by the unitary table top 16 and an appropriate push button on the switch box 92 is depressed by the operator to energize the first motor 46 causing the table top to vibrate generally lengthwise upon the vibration mountings 34. After a time, the first motor 46 is switched off and the second motor 62 is started as soon as the patient is shifted to a point at which the body applicator pads 38, 40 are aligned with the proper massage points on the patient. Then the hand levers 138 and 140 are adjusted to set the mechanism 88 and stroke setting linkages 126, 128 whereby the pads 38 and 40 move together in phase, or out of phase and with the same stroke or different strokes of travel as required. When the stroke setting mechanism brings the slide blocks 112 into alignment with the pin neutral axis defined by the driving member shaft 102, Figure 5, neither pad 38 or 40 moves. This condition prevails even when the vibrating table top 16 is being oscillated on its vibration mountings 34. From this neutral position of the stroke setting mechanism, the second motor 62 may be left running for possible further use or may be turned off, but in either case the pads 38, 40 remain stationary and the patient is shifted and his feet are then secured to the foot supports 84 by means of straps, not shown. The third motor 90 is then switched on to set it in motion to impart Symmetrical motion to the foot supports 84. As a consequence the patients legs and ankle muscles are manipulated in a fashion whereby both feet move toward'the patient at the same time and then they rnoveaway from the patient. Simultaneously, they are first beingspread apart and then they approach one another and at the same time, they are under-going atwi stingmot ion best appreciated in Figure9'. Thus, in- Figure 9, the supports 84 move from their solid line posit-ion in which they are tilted away from one another into aposi-tionshown by the dotted lines 84a in which they tilt 'tow-a-rd one another. In the plane perpendicularthereto they are also tilting the feet of the patient respectivelytoward him and away from him as his feet bodily move toward andaway from him.

The plane of rotation of the unbalaneed weight-60 extends at right angles to the general longitudinal direction of the unitary table top 16--and rotation causes the barely perceptible vibrations desired of-the table top essentially in the fore and aft direction. The vibration mountings 34 are resistant to compression and tension forces but not to shear forces and therefore the table top 16 has little tendency to vibrate up and down.

It will be readily appreciated that the present single massage table affords the foregoing three-way massaging action on different parts of a-patient reclining thereon and that all three motions are power driven so as to afford a very relaxing massage action.
