DESCRIPTION OF A PREFERRED EMBODIMENT
A therapeutic vibration apparatus 10 according to the present invention is shown in Fig. 1. The apparatus 10 includes a handle bar 12 which is attached to a "U"
shaped support frame 14 with an upright support standard 16 as shown in Fig. 2. The distal ends of the "U" shaped support frame 14 are attached to a base frame 18 with bolts 20 as shown in Fig. 2. The "U" shaped frame 14 is provided with a pair of rollers 22 so that when the upright support standard 16 is tilted the vibration apparatus 10 can be easily moved to a different location.
As shown in Fig. 3, the base frame 18 is a rectangular frame having four frame members 24, 26, 28 and 30. A non-skid support 32 is mounted at each of the four corners of frame 18 as shown in Fig. 3. In addition, an adjustable height non-skid support 33 is mounted to frame member 28 as shown in Fig. 1.
A series, of resilient supports are mounted to the base frame 18 as shown in Figs. 3 and 4. Four resilient supports 34 are provided with one resilient support 34 located at each corner of the base frame 18. An additional two intermediate resilient supports 35 are located on each of the base frame members 24 and 28.
Further a central resilient support 37 is located between the respective two intermediate resilient supports 35 on the base frame members 24 and 28.
In a preferred embodiment, the resilient supports 34, 35 and 37 are constructed of a rectangular sheet of rubber material which has been bent into an arch configuration. Each free end of the resilient supports 34, 35 and 37 are mounted to the frame 18 with a channel bracket 36.
A vibration platform 38 rests on top of the resilient supports 34 as shown in Fig. 4. The vibration platform is secured to the base frame 18 with bolts 40 which extend through the vibration platform 38 and then through a respective resilient support 34 located at each corner of the base frame 18 as shown in Fig. 3. A
rectangular washer 42 is provided on the underside of the resilient support 34 to prevent slippage of the bolt 40 through the resilient support.
In a preferred embodiment, the resilient supports 34 have a height greater than resilient supports 35 and 37.
The resilient supports 37 have the least height and the intermediate resilient supports 35 have a height between the height of resilient supports 34 and resilient supports 37. The reason for the varying heights is that corner supports will support a person or a person lifting weights up to about 450 pounds. When the weight is greater than this, the vibration platform will be pushed downwardly against the resilient supports 34 to rest on top of resilient supports 35. The resilient supports 34 and 35 will support weight up to about 850 pounds. With a greater weight the vibration platform 38 will be pushed further downwardly until it rests on resilient supports 37. With this arrangement, the vibration platform 38 will accommodate different weights without the necessity of providing a single resilient support to accommodate the maximum weights. Thus, vibration platform 38 has less stiffness with lower weights than with heavier weights positioned on the vibration platform 38.
In a preferred embodiment, a set offour angle iron members 44, 46, 48 and 50 are mounted to the underside of platform 38 as by welding to provide rigidity to the vibration platform 38. Amounting plate 52 is also welded to the underside of the vibration platform 38.
As shown in Fig. 3, a motor driven vibrator is used for vibrating the vibration platform 38. This vibrator includes a conventional, three phase, reversible dual-shaft motor 54. The motor 54 is provided with a pair of drive shafts 56 extending out either side of motor 50 as shown in Fig. 3. The distal ends of the drive shafts 56 are mounted in spaced apart pillow block bearings 58 and 60 which are mounted to the mounting plate 52 with bolts.
An eccentrically-mounted fixed weight 62 and an eccentrically-mounted rotatable weight 64 are mounted to each shaft 56 between the two pillow block bearings 58 and 60.
The fixed weight 62 is shown in Fig. 5. This weight 62 includes an off-center bore 66 for receiving the shaft 56. A pair of threaded bores 68 are provided in adjacent edges of the first weight 62 as shown in Figs. 5 and 6.
The bores 68 extend through the fixed weight 62 and into the bore 66. The threaded bores 68 receive set screws (not shown) for securing the fixed weight 62 to the drive shaft 56.
A stop 70 is secured to one face of the first weight 62 adjacent the bore 66 as shown in Figs. 5 and 6 and extends outwardly in a perpendicular relation to a face of the fixed weight 62 and in parallel relation with a longitudinal axis of bore 66. In a preferred embodiment, a polyethylene sleeve 72 is mounted on the stop 70.
The rotatable weight 64 is shown in Figs. 7 and 8.
This rotatable weight is provided with an off-center bore 74 for receiving the shaft 56. A spacer 76 is mounted to one side of the rotatable weight 74 and has a bore 78 axially aligned with the bore 74 as shown in Fig. 7. The bore 74 and 78 are sized to rotatably receive the shaft 56.
The fixed weights 62 and the rotatable weights 64 are sized so that when these weights revolve with the drive shafts 56, they.do not strike the mounting plate 52.
With this construction, the vibration platform vibrates with each revolution of the drive shaft 56 because of the unbalanced weight provided by the fixed weights 62 and the rotatable weights 64 mounted on the drive shafts 56. When the motor 54 is energized, the fixed weight 62 will rotate with the shaft 56 and the stop 72 will catch the rotatable weight 62. Depending on the direction of rotation of the motor 54, the rotatable weight 62 will be caught by stop 72 either on the side of shaft 56 in alignment with the eccentric portion of the fixed weight 62 or on the side of shaft 56 opposite the eccentric portion of the fixed weight 62. When the fixed weight 62 and rotatable weight are aligned, the amplitude of vibration increases because of the increased weight on one side of the shaft 56. When the direction of the motor 54 is reversed and the rotatable weight 62 is on the opposite side of shaft 56, the amplitude of vibration is reduced, because the weight of the eccentric portion of fixed weight 62 is off set by the weight of the eccentric portion of the rotatable weight 64.
As will be noted, simply by reversing the direction of the motor 50, the amplitude of the vibration is either increased or decreased depending on the direction of rotation of the motor.
It is to be also noted that by increasing the mass of the fixed weight 62, the amplitude of vibration can also be varied. By increasing the mass, the amplitude of vibration is increased and by decreasing the mass, the amplitude of vibration is lessened.
In order to increase the mass of the fixed weight 62, the fixed weight 62 is provided with a series of threaded holes 80 and 82 as shown in Figs. 5 and 6. To increase the mass of the fixed weight 62, a bolt (not shown).is threaded into one or both of the threaded holes 78 or 80. The weight of the bolts inserted increase the mass of the fixed weight 62.
A conventional controller 84 is used for controlling the speed and direction of rotation of the motor 54. In a preferred embodiment, the controller 84 is a three-phase AC adjustable speed drive, micro series inverter manufactured by Leeson. The controller 84 is electrically connected in a conventional manner to an invertor 86 and the motor 54 with conductor cable 88.
The controller 84 includes an internal micro processor which allows a user to control the speed of the motor 54 as well as the direction of rotation of the motor 54.
Further, the controller 84 includes a timer for setting the time during which the motor is energized. A power cord 90 connects the invertor 86 to a conventional power source.
While the fundamental novel features of the invention have been shown and described, it should be understood that various substitutions, modifications and variations may be made by those of ordinary skill in the art without departing from the spirit or scope of the invention. Accordingly, all such modifications or variations are included in the scope of the invention as defined by the following claims.
Further a central resilient support 37 is located between the respective two intermediate resilient supports 35 on the base frame members 24 and 28.
In a preferred embodiment, the resilient supports 34, 35 and 37 are constructed of a rectangular sheet of rubber material which has been bent into an arch configuration. Each free end of the resilient supports 34, 35 and 37 are mounted to the frame 18 with a channel bracket 36.
A vibration platform 38 rests on top of the resilient supports 34 as shown in Fig. 4. The vibration platform is secured to the base frame 18 with bolts 40 which extend through the vibration platform 38 and then through a respective resilient support 34 located at each corner of the base frame 18 as shown in Fig. 3. A
rectangular washer 42 is provided on the underside of the resilient support 34 to prevent slippage of the bolt 40 through the resilient support.
In a preferred embodiment, the resilient supports 34 have a height greater than resilient supports 35 and 37.
The resilient supports 37 have the least height and the intermediate resilient supports 35 have a height between the height of resilient supports 34 and resilient supports 37. The reason for the varying heights is that corner supports will support a person or a person lifting weights up to about 450 pounds. When the weight is greater than this, the vibration platform will be pushed downwardly against the resilient supports 34 to rest on top of resilient supports 35. The resilient supports 34 and 35 will support weight up to about 850 pounds. With a greater weight the vibration platform 38 will be pushed further downwardly until it rests on resilient supports 37. With this arrangement, the vibration platform 38 will accommodate different weights without the necessity of providing a single resilient support to accommodate the maximum weights. Thus, vibration platform 38 has less stiffness with lower weights than with heavier weights positioned on the vibration platform 38.
In a preferred embodiment, a set offour angle iron members 44, 46, 48 and 50 are mounted to the underside of platform 38 as by welding to provide rigidity to the vibration platform 38. Amounting plate 52 is also welded to the underside of the vibration platform 38.
As shown in Fig. 3, a motor driven vibrator is used for vibrating the vibration platform 38. This vibrator includes a conventional, three phase, reversible dual-shaft motor 54. The motor 54 is provided with a pair of drive shafts 56 extending out either side of motor 50 as shown in Fig. 3. The distal ends of the drive shafts 56 are mounted in spaced apart pillow block bearings 58 and 60 which are mounted to the mounting plate 52 with bolts.
An eccentrically-mounted fixed weight 62 and an eccentrically-mounted rotatable weight 64 are mounted to each shaft 56 between the two pillow block bearings 58 and 60.
The fixed weight 62 is shown in Fig. 5. This weight 62 includes an off-center bore 66 for receiving the shaft 56. A pair of threaded bores 68 are provided in adjacent edges of the first weight 62 as shown in Figs. 5 and 6.
The bores 68 extend through the fixed weight 62 and into the bore 66. The threaded bores 68 receive set screws (not shown) for securing the fixed weight 62 to the drive shaft 56.
A stop 70 is secured to one face of the first weight 62 adjacent the bore 66 as shown in Figs. 5 and 6 and extends outwardly in a perpendicular relation to a face of the fixed weight 62 and in parallel relation with a longitudinal axis of bore 66. In a preferred embodiment, a polyethylene sleeve 72 is mounted on the stop 70.
The rotatable weight 64 is shown in Figs. 7 and 8.
This rotatable weight is provided with an off-center bore 74 for receiving the shaft 56. A spacer 76 is mounted to one side of the rotatable weight 74 and has a bore 78 axially aligned with the bore 74 as shown in Fig. 7. The bore 74 and 78 are sized to rotatably receive the shaft 56.
The fixed weights 62 and the rotatable weights 64 are sized so that when these weights revolve with the drive shafts 56, they.do not strike the mounting plate 52.
With this construction, the vibration platform vibrates with each revolution of the drive shaft 56 because of the unbalanced weight provided by the fixed weights 62 and the rotatable weights 64 mounted on the drive shafts 56.

Depending on the direction of rotation of the motor 54, the rotatable weight 62 will be caught by stop 72 either on the side of shaft 56 in alignment with the eccentric portion of the fixed weight 62 or on the side of shaft 56 opposite the eccentric portion of the fixed weight 62. When the fixed weight 62 and rotatable weight are aligned, the amplitude of vibration increases because of the increased weight on one side of the shaft 56. When the direction of the motor 54 is reversed and the rotatable weight 62 is on the opposite side of shaft 56, the amplitude of vibration is reduced, because the weight of the eccentric portion of fixed weight 62 is off set by the weight of the eccentric portion of the rotatable weight 64.
