Abstract
Description
- This invention relates to an amplitude change-over device for a body vibration machine, particularly to one able to change and adjust the strength of amplitude and the value of gravitational acceleration for tallying with a user's requirement in training muscular strength by adjusting a single motor with same frequency to rotate clockwise or counterclockwise.
- An amplitude change-over device for a body vibration machine according to the preamble of claim 1 is already known from
EP 1 813 245 A . - In particular,
EP 1 813 245 A provides an apparatus for the stimulation of the human body by means of vibrations comprising a vibrating plate, which can be activated to vibrate with a platform. The apparatus defines how the user is to position him- or herself during standard operation: a forward direction (and consequently also a backward direction) is defined by gripping devices (handles) and/or markings. I.e. the sagittal plane of the user in relation to the apparatus is defined. The apparatus comprises a vibration activator with at least one rotary driving mechanism in relation to a rotational axis and an electric motor, which can trigger an eccentric weight into a rotating motion, wherein the position of the rotational axis in relation to the vibrating plate is fixed. The rotational axis, or all rotational axes, is/are selected to extend transversely to the defined sagittal plane. - In reality, our daily activities are affected anytime and anyplace by gravity, and the influence of gravity is a basis for developing our muscular strength. Conventional weight training acted on a human body (gravity Fz) is to employ extra weight and load to be imposed upon the human body. Substantially human body can naturally enhance its muscular strength to cope with increase of weight and load imposed thereon. Dumbbells and other weight training apparatuses are extra loads for training muscular strength. During taking exercises, a man's body will carry out self-adjustment and correction in accordance with increase of extra loads and hence a man's muscular power can be strengthened and his body will become stronger than ever before.
- Compared with conventional weight training, body vibration training does not need extra loads, so it will not be affected by gravity but by acceleration. When an object or a human body changes its velocity in a very short time, assimilation of acceleration will be expanded. According to a formula: Fz (gravity)= m (individual body weight) × a (gravitational acceleration, m/sec.2), when acceleration (a) increases, a body working strength will also be actuated to increase. In comparison with conventional weight training (added with loads), vibration training without extra loads can attain an effect of exercise training faster than the conventional weight training; therefore, body vibration machines used for training a man's muscular power have been widely used.
- A conventional
body vibration machine 10, as shown inFigs. 1∼4 , includes a standing table 11, anupright post 15, ahandrail 16 and acontrol faceplate 17 combined together. - The standing table 11 is positioned over a
base plate 12, and a plurality of buffering andelastic support cylinders 13 are assembled between thebase plate 12 and the standing table 11 to connect them together so that when a user stands on the standing table 11, the standing table 11 can produce a buffer effect. The standing table 11 has an intermediate portion of its underside secured with the outer casing of amotor 14, as shown inFig. 3 , and themotor 14 has a rotatingshaft 140 with two opposite ends respectively fixed thereon with aneccentric plate 141. Thus, after themotor 14 is started to operate, the twoeccentric plates 141 fixed on the opposite ends of the rotatingshaft 140 will make themotor 14 produce eccentric vibration, and the standing table 11 secured with the outer casing of themotor 14 will be actuated to vibrate synchronously. - The
upright post 15 extending upward is fixedly connected with a front end of thebase plate 12. - The
handrail 16 and thecontrol faceplate 17 are fixed at the upper end of theupright post 15. When standing on the standing table 11, a user can hold thehandrail 16 for supporting and controlling the working conditions of thebody vibration machine 10 by means of thecontrol faceplate 17. - In using of the conventional
body vibration machine 10, as shown inFig. 1 , after a user stands on the standing table 11 and holds on thehandrail 16, themotor 14 is started to operate and, by its eccentric vibration force, driving the standing table 11 to vibrate continuously, and simultaneously the user's body will be actuated to produce continuous vibration, thus achieving effect of exercise training. - However, the conventional
body vibration machine 10 can produce only one single amplitude. Under the circumstances, if users of different body conditions need to use different-strength amplitudes, it is necessary to change the extent of the amplitude and for this purpose, theeccentric plate 141 at the opposite ends of the rotatingshaft 140 of themotor 14 have to be replaced, thus increasing trouble in disassembling and replacing of theeccentric plates 141 and resulting in inconvenience in use. In another case, if theeccentric plates 141 are not to be replaced, then two motors with different amplitudes have to be used for change of amplitude, thus increasing producing cost and weight of the body vibration machine. - The objective of this invention is to offer an amplitude change-over device for a body vibration machine, able to change the extent of amplitude by using a single motor so that a user can choose proper amplitude for use according to exercise strength, principle of gradual progress and exercise adaptability.
- The feature of this invention is two eccentric units respectively fixed on the opposite ends of a rotating shaft driven to rotate by a motor. Each eccentric unit consists of an eccentric driving plate secured with the rotating shaft for rotating together and an eccentric driven plate movably fitted on the rotating shaft abutting one side of the driving plate. Either one of the driving plate or the driven plate has its surface bored with an arc-shaped slide groove with the rotating shaft acting as a pivot, and another one has a corresponding end of its surface fixed with a projecting stud inserted in the slide groove. The motor of this invention is a right-handed and left-handed one. By so designing, the motor can be chosen to rotate clockwise or counterclockwise to change an included angle between the driving plate and the driven plate for changing centrifugal force, and hence strength of amplitude can be optionally adjusted for use by changing the rotating directions of a single motor.

Figs. 5 ,6 and7 , includes a standing table 20, abase plate 21, amotor 22, an upright post, a handrail, a control faceplate and twoeccentric units 23 combined together. - The upright post, the handrail and he control faceplate are the same as those in the conventional body vibration machine, so their description are omitted here. Besides, those components can be saved in a body vibration machine, as a user can stand on the standing table, with a hand holding something stationary.
- The standing table 20, as shown in
Fig, 5 , is positioned over thebase plate 21, and a plurality of buffer andelastic support cylinders 200 are assembled between thebase plate 21 and the standing table 20 to connect them together. - The
motor 22 has its outer casing secured thereon with afixing frame 220 to be firmly combined with an intermediate portion of the underside of the standing table 20, as shown inFig. 8 . Themotor 22 can be a right-handed and left-handed one provided with a rotatingshaft 221 having the opposite ends respectively and correspondingly fixed with theeccentric unit 23. Thus, when themotor 22 is started, the two oppositeeccentric units 23 on the rotatingshaft 221 driven by themotor 22 will be rotated to produce a centrifugal force, and the standing table 20 fixed with the outer casing of themotor 22 will be actuated to vibrate. - The improvements made in the invention are described below.
- The two
eccentric units 23 fixed on the opposite ends of the rotatingshaft 221 driven by themotor 22 are respectively composed of aneccentric driving plate 230 and an eccentric drivenplate 231. - The
eccentric driving plate 230 is of a sector shape, having its eccentric portion secured with the rotatingshaft 221 of themotor 22 for rotating together with the rotatingshaft 221. Thedriving plate 230 is bored with an arc-shaped slide groove 2301 with the rotatingshaft 221 acting as a pivot. - The eccentric driven
plate 231 is also of a sector shaped, having its eccentric portion movably fitted on the rotatingshaft 221 adjacent to one side of thedriving plate 230, with abush 232 fitted on the rotatingshaft 221 to separate thedriving plate 230 from the drivenplate 231 so as to prevent them from producing surface contact friction. The drivenplate 231 is provided with a projectingstud 2310 at one side facing thedriving plate 230. The projectingstud 2310 has its outside fitted thereon with a sound-proof sleeve 2311 and then they are together inserted in the arc-shaped slide groove 2301 of thedriving plate 230. After fitted on the rotatingshaft 221, the drivenplate 231 is fixed with the rotatingshaft 221 by means of arubber gasket 233 and alocking nut 234 for preventing the drivenplate 231 from slipping off therotating shaft 221, and then twomotor covers 222 are respectively fixed with the outer casing of themotor 22 for covering up both thedriving plate 230 and the drivenplate 231. - After foresaid components under the standing table 20 are combined together, the body vibration machine is finished assembling, as shown in
Figs. 7 and 8 . After a user stands on the standing table 20, themotor 22 is started to operate and drive the standing table 20, and the user's body to produce continuous vibration, thus attaining effect of exercise training. Two conditions of operating and using the body vibration machine are described as follows. - 1. When the
rotating shaft 221 of themotor 22 is controlled by the control faceplate to rotate clockwise, as shown inFigs. 7 and 8 , both themotor 22 and the drivingplates 230 will be driven to rotate clockwise simultaneously. When themotor 22 and the drivingplates 230 are rotated to reach a limit location where one end of the arc-shapedslide groove 2301 of the drivingplate 230 touches the projectingstud 2310 of the drivenplate 231, the drivenplate 231 will be hooked and actuated by the drivingplate 230 to rotate together with the drivingplate 230 synchronously. At this time, the drivingplate 230 and the drivenplate 231 are staggered in position with a large included angle. According to a formula: F (centrifugal force) = m (mass) × w2 (angular velocity) × r (radius), the included angle and the centrifugal force are of reverse ratio. Therefore, the amplitude of themotor 22 and the standing table 20 becomes low. - 2. When the control faceplate controls the
rotating shaft 221 of themotor 22 to rotate counterclockwise, as shown inFigs. 9 and 10 , themotor 22 and the drivingplates 230 will synchronously rotate counterclockwise. When the drivingplates 230 are rotated to reach a limit location where the other end of the arc-shapedslide groove 2301 of the drivingplate 23 touches the projectingstud 2310 of the drivenplate 231, the drivenplate 231 will be hooked and actuated by the drivingplate 230 to rotate together with the drivingplate 230 synchronously. At this time, the drivingplate 230 and the drivenplate 231 are overlapped in position and their included angle becomes small, and according to the formula: F (centrifugal force) = m (mass) × w2 (angular velocity) × (radius), the included angle and the centrifugal force are of reverse ratio; therefore, the centrifugal force is increased, and the amplitude of themotor 22 and the standing table 20 becomes high. - As can be understood from the above description, the amplitude of the standing table 20 and the
motor 22 can be changed only by controlling themotor 22 to rotate clockwise or counterclockwise. Thus, by employing a single motor, the body vibration machine of this invention can produce two different-strength amplitudes to be optionally chosen for use in accordance with different body conditions of the users. - A second preferred embodiment of an amplitude change-over device for a body vibration machine in the present invention, as shown in
Fig. 11 , has almost the same structure as that described in the first preferred embodiment, except that the drivenplate 231 instead of the drivingplate 230 is bored with the arc-shapedslide groove 2301, while the drivingplate 230 instead of the drivenplate 231 is provided with the projectingstud 2310, thus equally enabling the drivingplate 230 and the drivenplate 231 to be mutually hooked and actuated to rotate together. - A third preferred embodiment of an amplitude change-over device for a body vibration machine in the present invention, as shown in
Figs. 12 ,13 and 14 , is to have therotating shaft 221, which has twoeccentric units 23 fixed thereon, pivotally inserted and assembled on twosupport bases 224 located near one side of themotor 22. The drivingshaft 223 of themotor 22 and therotating shaft 221 have their corresponding ends respectively fixed thereon with agear 225, and a drivingbelt 226 is connected with the twogears 225 for driving therotating shaft 221 to rotate together with the drivingshaft 223 of the motor synchronously. - While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the scope of the invention.
