Abstract
A vibrating mechanism for a body vibration machine includes a step (80A), a bottom board (80B) and a driving mechanism that has upper linking bars (70A) and lower linking bars (70B) connected with the step and the bottom board, and plural direction-restricting sets (90) installed between the step and the bottom board. Each position-restricting set has a cylinder (91) and a guiding bar (94) inserted in the cylinder to enable the step moved vertically. A crank (60) is connected with the upper linking bar and the lower linking bar via a pivotal shaft (61) so that it can spontaneously drive the pivotal shaft to move circularly, enabling the step to move vertically. Moreover, a small motor unit is powerful enough as the step is driven to move by the upper and the lower linking bar instead of by the driving motor directly.
Description
- This invention relates to a vibrating mechanism of a body vibration machine, particularly to one that demands only a relatively small driving motor to move its step vertically in a stable amplitude of vibration.
- Commonly, there are various sorts of conventional body vibration machines. As shown in
Figs. 1 - 3 , a first conventional body vibration machine includes a vibratingmotor 10 able to work eccentrically, and a connectingbody 11 positioned on the top of the vibratingmotor 10 for fixing with the bottom of astep 12 to keep the vibratingmotor 10 hung in the air. In addition, there are plural pairs of direction-restrictingposts 13 positioned correspondingly on two lateral sides of abottom base 14, used to support thestep 12. Because thestep 12 is supported by the direction-restrictingposts 13, the M (the amplitude of vibration of the step 12) is directly proportional to the ΣF (resultant force), wherein ΣF = F (centrifugal force) N L (load). That is, when the L (the weight of a man standing on the step 12) is increased, the ΣF is to become smaller, obtaining a relatively smaller M. On the contrary, a larger M is to be attained if thestep 12 is loaded with a lighter person. Therefore, the M is to alter in accordance with the weight of the person standing on thestep 12, becoming unsteady. Moreover, as the vibratingmotor 10 is fixed with thestep 12 to work eccentrically and thestep 12 is supported by the direction-restrictingrods 13, thestep 12 is to be vibrated in X-, Y- and Z-direction, unable to move just up and down. - Additionally, as shown in
Fig. 4 (A,B,C,D), a second conventional body vibration machine is provided with a drivingmotor 20, arotator 21 fixed on aspindle 200 of thedriving motor 20, acrank 22 pivotally connected at aneccentric position 211 of therotator 21, and astep 23 having its bottom side pivotally fixed with the other end of thecrank 22. There are also plural pairs oftubular posts 24 positioned correspondingly at two sides of thedriving motor 20 and eachtubular post 24 is installed with a guidingbar 26 inside it. Thetubular post 24 and thedriving motor 20 are all fixed on abottom base 25. The guidingbars 26 are fixed together with thestep 23 at their top ends. In using, when thedriving motor 20 is turned on, therotator 21 is driven to rotate, and thecrank 22 is thus driven by therotator 21 to rotate spontaneously, enabling thestep 23 to move and vibrate just up and down as the guidingbars 26 are restricted to move inside thetubular posts 24. And, because thecrank 22 is connected with thestep 23 by its one end and with therotator 21 by the other end, thestep 23 is able to maintain stable vibration without being affected by a body's weight, overcoming the defect of the first conventional body vibration machine. But, in order to directly drive thestep 23 to move up and down, the drivingmotor 20 needs to be more powerful to do the job, resulting in a high cost. - The objective of this invention is to offer a vibrating mechanism of a body vibration machine, which can move a step vertically in a steady amplitude of vibration and does not need a large powerful driving motor so as to save cost.
- The main characteristics of the invention are a step, a bottom board and a driving mechanism. The driving mechanism is provided with two upper linking bars and two lower linking bars connected respectively with the step and the bottom board, and plural direction-restricting sets correspondingly installed between the step and the bottom board. Each of the direction-restricting sets has a cylinder fixed on the bottom board and a guiding bar inserted in the cylinder and connected with a bottom of the step to enable the step moved merely up and down. A crank is pivotally connected together with the upper linking bar and the lower linking bar by means of a pivotal shaft, so that the crank can spontaneously drive the pivotal shaft to move circularly to enable the step to move just up and down. And, instead of being driven by the driving motor directly, the step is driven by the upper linking bar and the lower linking bar to move up and down, able to save cost by using a smaller driving motor.

Fig. 10 (A,B,C,D) is a side view of the preferred embodiment of a vibrating mechanism of a body vibration machine in the present invention, showing how it works. - As shown in
Figs. 5 - 9 , a preferred embodiment of a vibrating mechanism of a body vibration machine in the present invention includes astep 80A, abottom board 80B and a driving mechanism. The driving mechanism is composed of adriving motor 30, asmall pulley 40 fixed on a spindle of thedriving motor 30, alarger pulley 50 linked with thesmall pulley 40 via abelt 41, two upper linkingbars 70A connected with thestep 80A and two lower linkingbars 70B connected with thebottom board 80B. Thelarge pulley 50 is provided with anaxial shaft 51 that is connected pivotally with aneccentric rod 52 at its two ends respectively. Eacheccentric rod 52 is connected pivotally with acrank 60 by its other end. Thecrank 60 is provided with apivotal shaft 61 located at the other end for connecting pivotally with an upper linkingbar 70A and a lower linkingbar 70B, so that thecrank 60 can drive thepivotal shaft 61 to rotate circularly to drag the upper linkingbar 70A and the lower linkingbar 70B, as shown inFigs. 8, 9 and10 . There are four direction-restrictingsets 90 positioned at four corners of thebottom board 80B for elastically supporting thestep 80A. And, as shown inFigs. 6 and8 , each of the direction-restrictingsets 90 is provided with acylinder 91 fixed on thebottom board 80B, abush 92 fixed on the top of thecylinder 90, apositioning disc 93 fixed on the bottom of thestep 80A to face exactly to acylinder body 91. Thepositioning disc 93 is provided with a female-threaded hole for screwing with a male-threaded portion located at a top end of a guidingbar 94 that is to be inserted into thecylinder body 91 through thebush 92, in order to restrict thestep 80A moving just up and down without swinging. In addition, aspring 95 is installed between thebush 92 and thepositioning disc 93 for elastically supporting thestep 80A. - In using, as shown in
Fig. 10 , when thedriving motor 30 is turned on, theeccentric rod 52 is to be driven by theshaft 51 of thelarge pulley 50 to do a circular motion. Thecrank 60 is then spontaneously driven to enable thepivotal shaft 61 to move circularly, keeping the upper linkingbar 70A and the lower linkingbar 70B dragged to move. And, because thestep 80A is directly connected with and limited by the upper linkingbar 70A and the lower linkingbar 70B and the guidingbar 94 of the direction-restrictingset 90 is inserted inside thecylinder body 91 and thebush 92, it can only move up and down in a steady amplitude of vibration. Also, instead of being driven by thedriving motor 30 directly, thestep 80A is dragged to move via the upper linkingbar 70A and the lower linkingbar 70B that are connected pivotally together with thecrank 60 by means of thepivotal shaft 61. So, the drivingmotor 30 does not need too much power to do the job, with its cost possible to be reduced considerably. - While the preferred embodiment of the invention has 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 spirit and scope of the invention.
