2 Claims.

This invention relates to vibratory therapeutic machines, and more particularly to a vibrator of the platform type adapted to impart vibrations to the human body for the purpose of stimulating the blood circulation, relieving nervous or muscular tension, and for otherwise relieving bodily or psychological disturbances or discomforts.

A main object of the invention is to provide a novel and improved vibratory platform device upon which a person may stand and be given a treatment of a vibratory nature, said device being very simple in construction, including means for controlling the amplitude of the vibrations, and requiring very little maintenance.

A further object of the invention is to provide an improved vibrator of the platform type, said vibrator being relatively inexpensive to manufacture, being rugged in construction, being relatively quiet in operation and requiring only a relatively small driving means.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 12 is a schematic wiring diagram of the motor circuit employed in the machine of Figure 1.

Referring to the drawings, II designates a rectangular shell secured at its bottom portion on a plate member l2 provided with the supporting feet I3 located adjacent the respective corners of the plate member. The rear wall of the shell I I is designated at I4, and rigidly secured to said rear wall are the vertical arms l5, I5 of an upstanding, inverted, U-shaped, tubular support member IS. The top arm of the member I6 is 2 I shown at H, and serves as a hand rail, as will be subsequently described.

As shown in Figures 3 and 4, the rear wall M of shell II is reinforced at the connections of the arms l5, I5 thereto by a pair of horizontal angle bars I8, I8 through which the bolts I 9, l9, securing the arms l5, l5 to the wall l4, pass.

The angle bars l8, l8 may be secured in addition to the rear wall M byother bolts 20, 20.

Designated at 2| are respective cylindrical spring members, preferably of solid rubber or similar resilient material, the lower portions of the members 2| being secured inreceptacles 22 provided with dependingaxial studs 23. Secured to the respective side walls of the shell ll, shown at 24, 24, are a pair ofangle brackets 25, 25, the dependingstuds 23 of each of thereceptacles 22 passing through the horizontal arm of abracket 25 and being rigidly secured thereto by anut 26. Each of the solid spring members 2| extends a substantial distance above the top plane of the shell I I and has embedded in its upper portion an internally-threaded,axial insert 21. Designated at 28 is a plate member secured to the respective solid springs 2| bymachine screws 29 threadedly engaging theinserts 21. The top surface of theplate member 28 is provided with aresilient rubber pad 30 fastened thereto by any suitable means. Designated at 3! is an electric motor suspended beneath and rigidly secured to theplate member 28 at its central portion, as by a pair ofhanger brackets 32, 32, clampingly surrounding the motor housing, as shown in Figures 3 and 4.

The motor shaft is shown at 33 and projects axially from the motor at opposite ends. thereof. Secured to the respective ends of theshaft 33 are thearms 34, 34, each arm being formed with an enlargedweight ball 35, said weight balls being substantially in longitudinal alignment.

As shown in Figures 7 and 8, thearms 34 are rigidly secured to theshaft 33, as bytransverse bolts 36 passing through thearms 34 and theshaft 33 and secured bynuts 31. The radial distances of theweight balls 35 from theshaft 33 are the same for each of the weight balls, and when themotor 3| is energized, theweight balls 35, 35 rotate in synchronism and develop synchronous centrifugal forces acting on theshaft 33 and through themotor 3| and itsbrackets 32 on theplate 28, causing said plate to oscillate vertically as theshaft 33 rotates.

As shown in Figure 11, the shell II is braced at its corners byvertical angle bars 36 welded to the shell at said corners, thereby making the shell I I very rigid.

As shown in Figure 10, theresilient pad 36 may be securely clamped to theplate 28 bycorner screws 39 passing through washers 4G bearing on theresilient pad 30, said screws being threadedly engaged in theplate 28.

As shown in Figure 9, the supporting feet l3 are preferably made of rubber or similar resilient material, and are provided with threaded-inserts 4! in which are engaged the shanks of fas teningscrews 42 passing through theplate member 12.

Transversely secured to the upper portions of the vertical arms l5, l arehorizontal bars 43, 43 to the intermediate portions of which is secured arectangular housing member 44 containing a rheostat whose shaft projects through the front wall of thehousing 44 and has mounted thereon aknob 45. The front wall of thehousing 4% is provided with ascale plate 46 suitably calibrated, theknob 45 being provided with a pointer ll movable over the calibrations of thescale plate 36.

As shown in Figure 12, themotor 3! has connected to one of its terminals aline wire 38 and to the other of its terminals a wire it. Wire id is connected to the movable tap of the rheostat. shown at 55, and connected to the end terminal ofrheostat 50 is aline wire 51. Thewire 49 extends upwardly from the shell I I and enters the housing id through its lower wall, whereas thewire 51 passes through the lower wall of the housing i l and enters the right-hand, tubular 55, as viewed in Figure 1, and then passes downwardly through said tubular arm, enterin the housing H through the lower portion of the arm l5 and the rear wall 14 of the housing, as shown in Figure 5. The wires Q6 and 5! are joined to define a two-wire line cord 52 which emerges from the housing I! through the bottom wall E2 of said housing.

. As shown in Figure 12, the rheostat 58 is in normal open-circuit position, wherein the mov able tap of the rheostat disengages from the winding thereof and whereby themotor 35 is normally de-energized. using the machine stands on the platform defined. byplate 28 andpad 30, holding the rail I1 and energizesmotor 3! by rotatingknob 45 so that the movable tap of the rheostat engages the end of the rheostat winding. Since most of the rheostat winding is in series with themotor 3! at this point, the motor rotates at relatively low speed, thereby providing a low amplitude and slow speed of vertical oscillation of the platform. To increase the amplitude and speed of vertical oscillation. of the platform, theknob 45 is rotated so as to cut out more of the winding of the rheostat It is thus seen that the amplitude of oscil lation of the platform may be regulated by adjusting theknob 45, the degree of adjustment being indicated by the pointer 4'! in conjunction with thescale plate 46.

It will be apparent that the rail I! will be relatively stationary, while themotor 3| is energized, since the shell H is cushioned with respect to the oscillatingplatform 28 through the solid rubber springs 2!. Therefore, the person employing the machine may support himself while undergoing a vibratory treatment by grasping the horizontal rail I I. At the end of the period of treatment, the person undergoing such treatment merely rotates theknob 45 so that thepointer 41 is moved to the off position, whereby themotor 3! becomes de-energized.

While a specific embodiment of a vibratory therapeutic apparatus has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that 'no limitations In operation, the person said platform at the under side thereof and depending into said base, said motor including a shaft, and weights eccentrically carried by the motor shaft for imparting vibration to said platform upon rotation of the motor shaft, means resiliently mounting said platform on said base comprising angle brackets secured to said base one near each corner thereof and projecting inwardly of the base, upwardly opening receptacles secured one on each bracket, solid blocks of resilient material disposed at the under side of said platform within said receptacles, an internally screw threaded insert in each block at the end thereof adjacent said platform, and screws extending through corresponding apertures in said platform and threaded into the correspondinserts to secure said blocks to said platform, said blocks being'received at their ends remote from said platform by corresponding cups carried by said brackets.

2. In a platform vibrator having a hollow rectangular base provided with a bottom wall and an open upper side, a rectangular platform disposed at the upper side of said base, a motor secured to said platform at the under side thereof and depending into said base, said motor including a shaft, and weights eccentrically carried by the motor shaft for imparting vibration to said platform upon rotation of the motor shaft, means resiliently supporting said base and resiliently mounting said platform on said base comprising solid blocks of resilient material disposed at the outer side of said bottom wall and one near each corner of said base, a screw threaded insert in each block at the end thereof adjacent said bottom wall, screws extending through corresponding apertures in said bottom wall and threaded into said inserts to secure said blocks to the bottom wall of said base, angle brackets secured to said base one near each corner thereof above said bottom wall and projecting inwardly of the base, upwardly opening receptacles secured one on each bracket, solid blocks of resilient material disposed at the under side of said platform, an internally screw threaded insert in each of said last mentioned blocks at the end thereof adjacent said platform, and screws extending through corresponding apertures in said platform and threaded into corresponding inserts in the last mentioned blocks to secure such blocks 'to said platform, said last mentioned'blocks being received at their ends remote from said platform by corresponding receptacles carried by said brackets.
