This invention relates to an accessory to a treadmill which enables the treadmill to be converted into a whole body vibrator.
Recently, a product appeared on the market which was originally used by the Russians to rehabilitate their astronauts after being out in space for many days. This product or device is a machine that a person can stand on and it effects vibration on the whole body. The benefit of this is to loosen up joints and to improve blood and lymphatic circulation. Another claim is that by using the device, one gets the benefit of exercise without doing actual exercise. Whole body vibrator machines are relatively expensive. They cost anywhere from $4,000 to as much as $14,000 depending on the complexity of the device.
There is also a very inexpensive machine that consists only of a platform that is suspended in rubber cushions and the platform is vibrated only in a horizontal cyclical motion. This machine does not produce vibrations in a person's whole skeleton. It only vibrates the legs in a circular mode.
It would be desirable to provide a device which is very simple and it effects whole body vibration just like the expensive ones on the market but at a fraction of the cost. This invention has that objective.
The invention in its general form will first be described, and then its implementation in terms of specific embodiments will be detailed with reference to the drawings following hereafter. These embodiments are intended to demonstrate the principle of the invention, and the manner of its implementation. The invention in its broadest and more specific forms will then be further described, and defined, in each of the individual claims which conclude this Specification.
The invention, in one of its broader terms, is a mechanical device which can be attached to a treadmill where it converts the linear movement of the treadmill belt to an oscillating vertical motion and at the same time, circular motion. As such, the invention serves as a whole body vibrator. It includes a cylinder which has an eccentrically located shaft through it. The eccentric shaft extends beyond the ends of the cylinder. At the two opposite ends of the shaft there are bearings which are attached to a platform for a person to stand on. The platform is attached to the frame of the treadmill via a link, preferably a flexible bar, so as to localize the platform on the treadmill surface.
More particularly, the invention provides a whole body vibrator for attachment to a treadmill having a moving belt whereby the linear motion of the belt of the treadmill is converted to a vibratory motion comprising:
a platform on which a user may stand;
a roller for contacting the belt of a treadmill wherein the roller is eccentrically supported through bearings carried by said platform; and
a linkage connecting the platform to the treadmill to localize the platform on the belt and restrict longitudinal movement of the platform with respect to the belt, whereby the advancement of the treadmill belt causes the platform to effect an oscillating motion suited to provide a user, whose feet are positioned on the platform, with a whole body vibrator experience.
According to one variant of the invention the roller is carried by an eccentrically positioned axle shaft extending through the roller to provide protruding ends, said ends being supported by the bearings. According to another variant of the invention the roller has outer ends and eccentrically positioned shaft ends protruding from each of the respective ends of the roller to provide roller protrusions which are coupled to the platform through bearings carried by the platform.
The linkage which positions or localizes the platform on the belt is preferably longitudinally stiff but maybe laterally flexible. In order to better distribute the weight of the platform and corresponding pressure on the surface of the belt and to reduce noise, a resilient layer may be provided that extends over at least a portion of the surface of the roller that contacts the belt
In order to provide a user with a display that includes a presentation corresponding to the frequency of oscillation of the platform, the whole body vibrator of the invention may include:
The magnetic element may either be a piece of magnetic material, such as iron, or may be made magnetized material, such as magnetized iron or other permanently magnetized substance. The sensor may be a whole sensor or, conveniently when used in conjunction with a magnetized material, a simple coil that provides an electric pulse as the magnetized magnetic element passes by the sensor. Simple circuitry in the controller well-known to persons of the art can be constructed to convert this signal into a readout of the speed of the roller to the user.
The foregoing summarizes the principal features of the invention and some of its optional aspects. The invention may be further understood by the description of the preferred embodiments, in conjunction with the drawings, which now follow.
Wherever ranges of values are referenced within this specification, sub-ranges therein are intended to be included within the scope of the invention unless otherwise indicated. Where characteristics are attributed to one or another variant of the invention, unless otherwise indicated, such characteristics are intended to apply to all other variants of the invention where such characteristics are appropriate or compatible with such other variants.
The whole body vibrator as best seen in
While the roller 2 is shown with a single shaft with ends protruding from each end of the roller, instead, the outer ends of the roller may be provided with two shaft ends 24 (
The system for employing the vibrator further includes a linkage 6 connecting the platform 1 to the frame 10 of the treadmill 21 via support bar 11. Support bar 11 may be a simple bar as shown in
As shown in
During operation, the vibrator 20 is placed in position on the belt 8 of treadmill 21. A user then climbs on top of platform 1 of the device while using handles 9 to maintain their balance. The user may then activate the belt 8 of the treadmill 21 just as they would if the treadmill were to be used for walking or running. The motion of the belt 8 then frictionally drives and rotates the roller 2 while any longitudinal movement of platform 20 is restricted through the linkage 6.
As the roller 2 rotates under the force of belt 8, the eccentrically positioned roller moving eccentrically with respect to the shaft ends 4, imparts vertical oscillatory motion to the ends of the platform 1 as well as a limited horizontal oscillatory movement. The speed of the belt 8 determines the frequency of the oscillation and the user, standing atop the platform 1, is vibrated within this frequency. The user may continue to use handles 9 to maintain balance and may adjust the speed of belt 8 to produce a desired frequency of vibration. In other words, because of the eccentricity of the shaft through the roller, or the protruding shaft ends 24, the motion of platform 1 also has partial horizontal rotary motion as well as up and down motion. The position of the user's feet on the platform determines the amplitude of oscillation experienced by the user. The further apart the user's feet are, the larger the amplitude of oscillation.
The whole body vibrator 20 may be provided with a means to display useful information such as the frequency of vibration, the rate of rotation of the roller 2, or other such information to a user. This information may be measured with the arrangement shown in
Another possible modification includes cladding the roller 2 with a resilient layer, such as a sleeve 23, as shown in
Another arrangement is shown in
In
The stowaway mechanism works as follows. Referring to
By tightening nut 43 on bolt 42, bracket 37 is squeezed against brackets 39 and lock washers 41 provide friction so that bracket 37 becomes fixed at any position but, at the same time, linkage 6 is free to rotate around sleeve 40.
Item 38 also provides a resting spot for linkage 6 when in stowed position.
In operation, bracket 37 is set to an angle past the vertical position so that when the platform 1 is in stowed position, it will stay up due to gravity. See
The foregoing has constituted a description of specific embodiments showing how the invention may be applied and put into use. These embodiments are only exemplary. The invention in its broadest, and more specific aspects, is further described and defined in the claims which now follow.
These claims, and the language used therein, are to be understood in terms of the variants of the invention which have been described. They are not to be restricted to such variants, but are to be read as covering the full scope of the invention as is implicit within the invention and the disclosure that has been provided herein.
