The objective of this invention is to improve upon the prior art by the provision of an exercising machine which will exercise more effectively and strenuously the ankles, legs and thighs of stroke victims and the like with complete safety to the user. The machine possesses an improved mode of operation in comparison to the prior art inasmuch as the users two legs are simultaneously subjected to cyclic twisting in two directions, while simultaneously the entire lower torso is twisted cyclically at a different rate and in a different cycle from the legs. All of this exercising motion is produced by a simplified, sturdy and compact power drive mechanism which has a wide range of adjustability. Due to available adjustments, the degree of twisting imparted by the machine to an individuals leg or legs may be regulated to meet particular needs. While the exercise therapy is taking place, the subject stabilizes himself by grasping a convenient hand rail near waist level with one or two hands. The oscillatory foot rest platforms are recessed for further safety and stability and to assure a firm twisting action on the legs without slippage. The driving mechanism is extremely simple and eco nomical and provision is made for lubrication.
Other features and advantages of the invention will become apparent during the course of the following detailed description.

DETAILED DESCRIPTION Referring to the drawings in detail, wherein like numerals designate like parts and considering FIGS. 1 through 3 initially, the exercising machine comprises a broad horizontal base plate on which the oscillatory turntable 21 and individual leg exercising foot rest platforms 22 and 23 are mounted centrally in a unit, as will be fully described. A power drive mechanism for the oscillatory elements 21, 22 and 23 is secured to the base 20, below turntable 21 and includes a variable speed drive motor 24, a drive or transmission box 25 and an associated adjustable drive linkage 26 having components directly coupled to turntable 21 and foot rest platforms 22 and 23. The final component of the simplified power-driven exerciser consists of a sturdy horizontal U-shaped hand rail 27 spaced above the base 20 and supported by three vertical standards 28 whose lower ends are firmly secured to the base 20 by brackets 29. A control switch 30 for the electric drive motor 24 is conveniently located at the forward side of hand rail 27 in ready reach of the user of the machine. The hand rail 27 is preferably disposed about 3 feet above the elevation of turntable 21, the latter being about 1 foot above the base 20. These dimensions, while generally preferred, are not critical.
Continuing to refer to all of the drawing figures, a turntable shaft support housing 31 is disposed at the center of the machine base 20 and rises therefrom and is securely bolted to the base as at 32. The housing 31 contains a pair of spaced bearings 33 and 34 for the rotational support of a vertical turntable shaft 35 which extends well above the top of the housing 31 and is attached at its top through a plate or flange 36 to the bottom of relatively large circular turntable 21.
At diametrically spaced locations on the turntable 21, a pair of vertical axis guide sleeves 37 for vertical foot rest platform drive shafts 38 are secured as at 39 to the bottom of turntable 21, FIG. 5. The guide sleeves 37 contain spaced bearings 40 and 41 for the pair of drive shafts 38, whose upper ends are attached through flanges 42 to the bottoms of foot rest platforms 22 and 23. The guide sleeves 37 like the housing 31 are equipped with lubrication fittings 43.
The foot rest platforms 22 and 23 are preferably circular, as shown, and embody dual position footreceiving shallow recesses 44 in their upper sides so that the users feet are firmly implanted and will not slip relative to the oscillating platforms. The recesses 44 are produced by contoured insert sections 45 of plywood or the like formed separately from the platforms 22 and 23 and attached thereto as shown in FIG. 5.
The power drive means for the exercising machine includes the aforementioned motor 24 mounted near one side of the base 20 and coupled through a generally diagonal shaft 46 and flexible coupling 47 with the drive box 25, the latter being bolted at 48 to the base 20 near one corner thereof.
The drive box 25, FIG. 10, contains and supports a vertical axis crank shaft 49 held rotatably in two spaced bearings 50 and 51 at the bottom and top of the drive box. The crank shaft has two diametrically opposed cranks or eccentrics 52 within an upper dry chamber 53 of the drive box 25. A lower oil-filled chamber 54 is separated from the dry chamber by a sealed divider 55 and keyed to the crank shaft 49 within the oil-filled chamber is a worm gear 56 meshing with a worm 57 attached to the drive shaft 46. The worm 57 is fully enclosed within an extension 58 of the drive box or housing 25.
Attached to the two opposed eccentrics 52 of crank shaft 49 are push rods 59 and 60 employed in the operation of the turntable 21 and the two foot rest platforms, respectively. The rods 59 and 60 are preferably equipped with needle bearings at their connections with crank shaft eccentrics 52. A downturned terminal end 61 of push rod 59 is received in a selected one of several adjustment openings 62 in a lower crank arm 63, which crank arm is firmly clamped at 64 to tumtable shaft 35. By selecting a different opening 62, the degree of oscillation of turntable 21 may be adjusted as the crank shaft 49 revolves. Similarly, the rod 60 has a terminal end 65 adjustably connected to one arm 66 of a bell crank having a second generally right angular arm 67 rigid therewith. The arms 66 and 67 have adjustment openings 68, as shown. The bell crank composed of arms 66 and 67 has a hub 69 freely joumaled for rotation on the shaft 35 and this hub bears slidably on a hub portion 70 of crank arm 63.
The crank arm 67 is pivotally coupled adjustably at 71 with a shiftable drive rod 72 for two additional horizontally swingable crank arms 73, one of which is firmly clamped to each of the vertical foot rest platform drive shafts 38. Each arm 73 has plural adjustment openings 74 therein for the selective reception of terminal ends 75 of drive rod 72. Through the medium of the rod 72 and the two crank arms 73 pivoted thereto, movement of the bell crank arm 67 will impart simultaneous oscillatory movement to the two shafts 38 and to the foot rest platforms 22 and 23 secured thereto. The individual oscillation strokes of the two foot rest platforms may be adjusted by the selection of different ones of the openings 74 for coupling with the drive rod 72.
In light of the foregoing description, the operation of the exercising machine may be briefly summarized as follows.
With the subject planting his feet in the recesses 44, the motor switch 30 is turned on and the hand rail 27 is grasped for security and stability. The drive motor 24 and associated gearing will produce continuous rotation of crank shaft 49 in a selected direction. The opposed eccentrics 52 will simultaneously reciprocate the two push rods 59 and 60. The lower push rod 59 through its associated crank arm 63 will produce oscillatory movement of the turntable 21 to an extent regulated by the adjustment openings 62. Simultaneously, in an out of phase mode, due to the arrangement of the eccentrics 52, the upper push rod 60 and the bell crank composed of arms 66 and 67 and the drive rod 72 will produce oscillation of the arms 73, shafts 38 and foot rest platforms 22 and 23. The foot rest platforms 22 and 23 will oscillate in unison and in the same directions but will be out of phase with and therefore turning oppositely to the movement of turntable 21, as indicated by the arrows in FIG. 1. As a result of this unique action, the two legs of the subject will be subjected to a twisting exercise simultaneously while the torso is being turned or twisted oppositely to the direction of movement of the legs. As previously stated, the extent of movement can be adjusted through a considerable range. The exercise is strenuous and benefits the ankles, calves and thighs without danger of straining the limbs beyond safe limits. The entire apparatus is characterized by its simplicity and compactness. The drive linkage shown in FIG. 4 is located safely between the base and the large turntable 21. The many advantages of the machine should be apparent to those skilled in the art without further description herein.
It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of the invention or scope of the subjoined claims.
