17,18 of this carriage 19g and above-mentioned form of hooks, link with lifter 20 capable of expansion and contraction.

Above-mentioned lifter capable of expansion and contraction 20 is identical with the structure of above-mentioned lifter 12 capable of expansion and contraction, it has: cylindrical shell 20a, from the retractile active gage 20b of this cylindrical shell 20a, be installed in the gear-box 20c on cylindrical shell 20a top, the motor 20d that said gear case 20c is driven, and height detection unit 20e.Be pressed in the lower end of above-mentioned cylindrical shell 20a and formed female lining 20f in the left and right sides, this lining 20f internal thread in conjunction with

bolt

17h, 18h, this

bolt

17h, 18h are inserted through bearing 17g, the 18g in elevating

lever

17,18 front ends that are pressed into above-mentioned form of hooks, therefore, the bottom of lifter 20 capable of expansion and contraction by axle supporting for around about the axis rotation of (y) direction.

Above-mentioned active gage 20b is made of spin leading screw etc., has fixed carriage 20g in the top.This carriage 20g is bearing in by axle on the carriage 19g of above-mentioned pedestal 19 by pin 20h, can around about axis shake freely.The internal thread engagement that forms on above-mentioned ball-screw and the not shown gear inner peripheral surface in gear-box 20c, this gear is by the worm-gear driven on the output shaft that is fixed on motor 20d, thereby above-mentioned active gage 20b can extend/dwindle in cylindrical shell 20a, thereby makes the angle of inclination mayization of front and back (x) direction of above-mentioned pedestal 19 and then seat 2.Above-mentioned height detection unit 20e detects the height of above-mentioned pedestal 19 front ends thus with the displacement that sensor 20j reads the slit plate 20i that is connected with above-mentioned carriage 20g, and then detects the inclination angle of this pedestal 19.

In above-mentioned head motion 3, by the revolving force of worm screw 13b to the motor 13 of above-mentioned the 1st driven wheel 14 transmission, also the gear 14b from minor diameter transmits to the gear 15a of the 2nd driven wheel 15.Distolateral eccentric shaft 15b that formed at the 2nd driven wheel 15, this eccentric shaft 15b is inserted through after the bearing 3n that is located on the above-mentioned side plate 3c, be embedded in the self-aligning bearing 21a that an end of eccentric rod 21 is provided with, screw thread can be in conjunction with nut 21b, in case anti-avulsion falls on the external screw thread 15c that its front end forms.Another of the 2nd driven wheel 15 is distolateral injected the bearing 3n that is located on the above-mentioned side plate 3d after, screw thread is in conjunction with nut 3s, in case anti-avulsion falls on the external screw thread 15d that its front end forms.

The bearing surface of above-mentioned self-aligning bearing 21a forms sphere, and same self-aligning bearing 21c is also in the other end setting of eccentric rod 21.Be inserted through a distolateral eccentric shaft 22a who is formed at axle 22 in this self-aligning

bearing

21c, 22b prevents to come off with the E ring.The central portion 22c of axle 22 is supported to rotation freely by the bearing 11n that is pressed among the 11m of hole, and this hole 11 is formed on the rear end side of a swivel plate 11a who constitutes above-mentioned support unit 11, and, at another distolateral gear 22d that is formed with of axle.

Said gear 22d and formed internal tooth 23a engagement on the inner peripheral surface of the gear 23 that is disposed at the swivel plate 11a outside, moreover, the nut 22f that screw thread is used in conjunction with slip-off preventing on the external screw thread 22e that the front end of this gear 22d forms, above-mentioned axle 22 is become one with gear 23, rotation linkedly, the external tooth 23b that forms on the outer peripheral face of said gear 23 is with the worm screw 24b engagement in the output shaft 24a that is pressed into motor 24.Motor 24 is installed to the recess of accommodating that forms from the outside of above-mentioned swivel plate 11a by installing component 25.The anglec of rotation with above-mentioned axle 22 all-in-one-piece gears 23 is detected by encoder 26.As shown in Figure 6, the benchmark hole 23c that 26 pairs of encoders form on the end face of gear 23 detects, and along with the rotation of gear 23, the hole 23d that uniformly-spaced forms is counted, can detect the anglec of rotation of said gear like this, and then detect the position of shaking basic point of eccentric rod 21.

On the other hand, in above-mentioned head motion 3, the lower end side of front gear-box 3a and back gear-box 3b forms parallel to each other, portion has been pressed into and has formed

female lining

3x, 3y in the central, in conjunction with

bolt

11x, 11y, this

nut

11x, 11y are inserted through bearing 11j, the 11i that is installed on above-mentioned sloping shaft support plate 11d, the 11d at this

lining

3x, 3y internal thread.Like this, above-mentioned head motion 3 can be rotated as rotation with the straight line 11z that connects above-mentioned bearing 11j, 11i.So,, head motion 3 is shaken around rotation 11z if 15 rotations of above-mentioned the 2nd driven wheel then utilize the effect from this eccentric shaft 15b to eccentric rod 21.At this moment, eccentric rod 21 carry out with respect to side plate 3c approaching/deviate from displacement.But by above-mentioned self-aligning

bearing

21a, 21c, can not break away from from the 2nd driven wheel 15 and axle 22 respectively, can transmission of drive force.

And, if 24 pairs of gears 23 of said motor are rotated driving, then can make the eccentric shaft 22a that connects above-mentioned eccentric rod 21 other ends and then make the basic point that shakes of above-mentioned eccentric rod 21 carry out the lifting displacement.Thus, as the detailed description of back, can make the position around above-mentioned rotation 11z of the head motion 3 relative have skew with support unit 11, to can make head motion 3 and then seat 2 is shaken around rotation 11z around the position of above-mentioned rotation 11z inclination predetermined angular as benchmark.And, owing to drive eccentric shaft 22a with worm gear 24b and gear 23, so, can prevent that the angle of inclination is with load variations.

In the balance training 1 that constitutes as mentioned above, if motor 13 rotations, then pass through eccentric shaft 14c, 14e, elevating lever 17,18 and the restrictive axes 16 of the 1st driven wheel 14, make seat 2 in front and back (x) direction with move back and forth on (z) direction up and down, see from the side and depict oval track R1 as shown in Figure 9.So, the elevating lever 17,18 that utilizes 14 pairs of supportings of one the 1st driven wheel that the pedestal 19 of seat 2 has been installed drives, thereby with cramped construction just can the shaking of front and back (x) direction (moving back and forth) go up increase about the shaking of (z) direction (moving back and forth), depict the track R1 of above-mentioned ellipse, can expand mobile graphics.And, the shaking of (z) direction (moving back and forth) about shaking of existing front and back (x) direction increases newly, thus can activate trainer's autonomic nerve, strengthen the muscle strength around the leg simultaneously.Moreover, see it is from the side owing to depict from circle to the track of ellipse, so, the load of shaking human body smoothly and is continuously changed, can either reduce damage to human body, can improve the effect of motion again.

Here should be noted that, in the present embodiment, the gear ratio of the gear 15a of the gear 14b of the 1st driven wheel 14 and the 2nd driven wheel 15, and then front and back (x) direction and about cycle of shaking of (z) direction be x: 2, the decimal ratio of 1＜x≤1.2 is wished to be set in 1＜x＜2 wherein.For example if be set at 1.2: 2, then ratio of revolutions is 2: 1.2.

In Figure 10, represent that above-mentioned gear ratio is the track of the timing of 1: 1 and initial point at 0 ° of seat of seeing from the plane 2 when consistent.In the case, because shaking of producing of above-mentioned eccentric rod 21, seat 2 is depicted seen rearward straight path L11 from the plane from oblique the place ahead.At this moment the 1st driven wheel 14 (x direction of principal axis) and the engagement of the 2nd driven wheel 15 (y direction of principal axis) change, and promptly the change in location on each direction of principal axis of seat 2 is shown in Figure 11.And, under the situation with respect to 180 ° of the phase delays of the 1st driven wheel 14, the 2 driven wheels 15, only shake direction and change and promptly become same straight path.

To this,,, make seat 2 describe to overlook track L12 as illustrated in fig. 12 into circle then owing to the shaking of above-mentioned eccentric rod 21 if the engagement of above-mentioned the 1st driven wheel 14 (x direction of principal axis) and the 2nd driven wheel 15 (y direction of principal axis) is offset 1/4 cycle, promptly 90 ° constantly.At this moment the 1st driven wheel 14 and the engagement of the 2nd driven wheel 15 variation are shown in Figure 13.Example when Figure 12 and Figure 13 represent with respect to 90 ° of the phase delays of the 1st driven wheel 14, the 2 driven wheels 15.Leading 90 ° also become same circular trace when promptly postponing 270 °, just the starting point difference.Under the situation of other phase places of skew, become the track that above-mentioned displacement is synthesized in its deviation ratio.

On the other hand, the gear ratio of the gear 15a of the gear 14b of the 1st driven wheel 14 and the 2nd driven wheel 15 is if be made as 1: 2, then ratio of revolutions is 2: 1, if the timing of initial point is 0 ° of unanimity, then because the shaking of above-mentioned eccentric rod 21, seat 2 is depicted as illustrated in fig. 14 overlook track L21 for horizontal 8 words (from describing in interior week).At this moment the 1st driven wheel 14 and the engagement of the 2nd driven wheel 15 variation are shown in Figure 15.

And if 180 ° of the timing slips of initial point, then seat 2 is depicted the track L22 of horizontal 8 words (describing from periphery) as illustrated in fig. 16.At this moment the engagement of the 1st driven wheel 14 and the 2nd driven wheel 15 variation is shown in Figure 17.

Moreover with respect to the 1st driven wheel 14, if 90 ° of the phase delays of the 2nd driven wheel 15, then seat 2 is depicted the track L23 that overlooks to inverted v-shaped as illustrated in fig. 18.At this moment the 1st driven wheel 14 and the engagement of the 2nd driven wheel 15 variation are shown in Figure 19.With respect to the 1st driven wheel 14, if leading 90 ° of the phase place (postponing 270 °) of the 2nd driven wheel 15, then seat 2 is depicted the track L24 that overlooks to the V font as illustrated in fig. 20.At this moment the 1st driven wheel 14 and the engagement of the 2nd driven wheel 15 variation are shown in Figure 21.

Moreover, if the gear ratio of the gear 15a of the gear 14b of the 1st driven wheel 14 and the 2nd driven wheel 15 was made as 2: 1, then ratio of revolutions is 1: 2, if the timing of initial point is 0 ° of unanimity, then because the shaking of above-mentioned eccentric rod 21, seat 2 is depicted as shown in figure 22 overlook track L3 into vertical 8 fonts.

But the eccentric shaft 22a that shakes basic point as eccentric rod 21 is located at the position that does not produce in the head motion 3 around the deviation of rotation 11z.If produce above-mentioned deviation, then as described later, above-mentioned each track L1, L21, L22, L23, L3 occur to this bias direction skew.And rotation 11z is counted as level.Track when this rotation 11z tilts also will be narrated in the back.

So, as previously mentioned, because the gear ratio of the gear 15a of the gear 14b of the 1st driven wheel 14 and the 2nd driven wheel 15 is made as x: the decimal ratio of 2 (1＜x＜2), so engagement regularly changes in time, for example as above-mentioned shown in Figure 14, from overlooking the track L21 of horizontal stroke 8 fonts that are a direction rotation, track L23 through inverted v-shaped shown in Figure 180, the track L22 of horizontal stroke 8 fonts of other direction rotation shown in Figure 16, and the track L24 of V font shown in Figure 20, turn back to the track L21 of horizontal stroke shown in Figure 14 8 fonts once more, shake repeatedly.

Owing to like this gear ratio of the gear 15a of the gear 14b of the 1st driven wheel 14 and the 2nd driven wheel 15 is set at the decimal ratio, so, it or not the track of fixing, but the combination of shaking direction changes in time, can be rich in shaking of changing, can realize the good balance training of continuous usability that the trainer can not be weary of.And, by above-mentioned gear ratio is made as x: 2 (1＜x≤1.2), so the inboard of energy enough horizontal 8 zag trajectory L21, L22 enhancing trainer's shank and the muscle strength in the outside, with seesawing that V zag trajectory L24 and inverted v-shaped track L23 are produced, can strengthen the muscle strength around trainer's waist, strength well can balance exercises one's muscles.

Above state is to make the long diametric(al) of slotted

hole

17b, 18b become track under the state of vertical direction.Therefore, do not make lifter 20 capable of expansion and contraction stretch, make lifter 12 flexible carrying out under the above-mentioned situation of shaking capable of expansion and contraction, for example if elongation lifter 12 capable of expansion and contraction, then seat 2 leans forward from support unit 11, the track of the seat of describing by

eccentric shaft

14c, 14d, elevating

lever

17,18 and the restrictive axes 16 of the 1st driven wheel 14 2, seeing from the side becomes the elliptical path R2 that leans forward as shown in figure 23.And, in the case, if the composition of front and back (x) direction is replaced mutually with the composition of vertical (z) direction or is tilted certain more than the angle, then as shown in figure 24, compare with above-mentioned track R1 shown in Figure 9, though the stroke W1 of oval horizontal direction reduces to W1 ',, the stroke W2 of vertical direction increases shown in W2 '.So also can change the size of track R1, R2.

And, stretch by making lifter 20 capable of expansion and contraction, the inclination of seat 2 is changed.In the case, distance H 1 from head motion 3 (becoming the center of the above-mentioned restrictive axes 16 of shaking basic point) to seat 2 (center of shaking of pedestal 19) is to H1 ' variation, as shown in figure 25, long diametric(al) at slotted

hole

17d, 18d is under the state of vertical direction, the stroke W2 of vertical direction does not change, and the stroke W1 of horizontal direction is changed to W ".And, about on (y) direction, from also changing to the distance of seat 2 (center of shaking of pedestal 19) as the rotation 11z that shakes basic point, stroke changes.

Like this, stretch, can change the stroke that shakes by making

lifter

12,20 capable of expansion and contraction.And it is many more that lifter 20 capable of expansion and contraction extends, and the toe lateral of seat 2 deviates from above-mentioned rotation 11z more, can increase the stroke that shakes (described later waving reversed) around this rotation 11z.Thus, compare, can shake stroke by change in the present embodiment and adapt to above-mentioned situation, can make the user feel at ease to use with the situation that past the elderly and the little trainer's reduction speed of shaking of muscle power are used.And, can also increase stroke.Like this, the motion that adapts with trainer's physique, health, age, sex, muscle power etc. can be provided, the balance training that movement effects is good can be realized.

In addition,, stretches by

lifter

12,20 capable of expansion and contraction because being linked mutually, so, can change the movement locus and the stroke of seat 2 as described above on one side, make seat 2 oscilaltions on one side, can increase statokinetic variation and telepresenc, realize the motion menu that can not be weary of.

On the other hand, because being linked mutually, stretches by

lifter

12,20 capable of expansion and contraction, so, as shown in figure 26, do not change the angle of seat 2 (pedestal 19), the inclination angle of above-mentioned rotation 11z is changed in the face of vertical (z) direction from front and back (x) direction.That is to say, in Figure 26, be that 45 state is a normal condition with above-mentioned rotation 11z with respect to the tiltangle on ground 5, if dwindle lifter 12 capable of expansion and contraction from this state, then rotation 11z is near level; If make lifter 12 elongations capable of expansion and contraction, then rotation 11z attitude close to the vertical shape (promptly erectting).In Figure 26, represent support unit 11, head motion 3, elevating

lever

17,18 and the pedestal 19 of said reference state with solid line, dot the state that rotation 11z tilts to plumbness, on the Reference numeral of each several part additional " ' " represented.

The displacement big more (above-mentioned tiltangle is big more) of above-mentioned rotation 11z approaching vertical (z) direction of (x) direction (erecting) from front and back, the shaking that above-mentioned the 2nd driven wheel 15 and eccentric rod 21 etc. are produced around above-mentioned rotation 11z, can from about the shaking of (z) direction (waving) to (reversing (if shaking of seat 2 is centered close on the above-mentioned rotation 11z around shaking of approximate vertical (z) axis, the variation that can take place then deflection)) is big more, and, the composition that moves back and forth of front and back (x) direction that head motion 3 can be produced switches to the vertically composition that moves back and forth of (z) direction.So, mobile graphics is changed, and, variation along with this mobile graphics, the amplitude of each stroke can be changed, the moving picture that meets the position that the trainer should take exercise can be accessed, simultaneously, can make the moving picture variation, can realize that the trainer can not be weary of, the continuous good balance training of usability.

The example that table 1 expression waving angle changes with the variation of above-mentioned tiltangle.This waving angle is with the length of the offset of the eccentric shaft 15b in above-mentioned the 2nd driven wheel 15, eccentric rod 21, distance of 22 etc. changes from rotation 11z to axle.

In addition, rotation 11z erects come many more from level (θ=θ °), as described above, just from about the shaking of (y) direction (waving) switch to around vertical shaking of (z) axis.So the gear ratio of the gear 15a of the gear 14b of the 1st driven wheel 14 and the 2nd driven wheel 15 for example is under 1: 2 the situation, the track of seat 2 becomes the track L21 that overlooks as above-mentioned horizontal stroke 8 fonts shown in Figure 14, in Figure 27, shown in Reference numeral L21 ', reduce, generation be the increase of reversing shown in Reference numeral V1, the V2.This reverses with constantly different and different of the engagement of the 1st driven wheel 14 and the 2nd driven wheel 15, consistent with timing under the state of reference position P0 (displacement 0) if (0 ° of position of the 2nd driven wheel 15 and 0 ° of position consistency of the 1st driven wheel 14), then wave to the left and right more, shown in Reference numeral V1, what seat 2 reversed on its direction of waving is many more; Return to reference position P0 more, seat 2 reverses be eliminated many more on the direction opposite with Reference numeral V1.In the case, can further increase movement effects.

In contrast to this, if according to above-mentioned 1: 2 gear ratio, make 0 ° of position of the 2nd driven wheel 15 and 180 ° of position consistency of the 1st driven wheel 14, even then identical horizontal stroke 8 fonts also can become above-mentioned track L22 shown in Figure 16.This situation is opposite with above-mentioned situation, wave to the left and right more, wave on the direction of (relative) on the contrary seat 2 as Reference numeral V2 be shown in and its and reverse manyly more, return to the reference position more, on the direction opposite with Reference numeral V2, seat 2 reverses be eliminated many more.In the case, can carry out soft motion.

And, under the situation as above-mentioned V font shown in Figure 20, wave to the left and right big more, shown in above-mentioned Reference numeral V1, its wave on the direction seat 2 reverse many more, shown in Reference numeral V2, in the side of waving with it in the opposite direction seat 2 reverse many more.

Moreover, link to offset mutually flexible caused inclination by

lifter

12,20 capable of expansion and contraction, can change seat 2 height overhead, even the mechanism that makes the seat lifting is not set in addition, also can be easy to make about the trainer according to trainer's height.

And, make seat 2 keep heeling condition constant, improving under the local situations such as movement effects, retractile lifter 20 also can not eliminated all changes of inclination of the flexible caused seat 2 of lifter 12 capable of expansion and contraction, can keep tilting wishing the state of angle.And, under the situation that seat 2 is installed with respect to pedestal 19 half-twists, shaking of above-mentioned head motion 3, about shaking of (y) direction become moving back and forth of vertical (z) direction in (moving back and forth), the track of the seat of seeing from front and back 2 becomes above-mentioned ellipse.And, the shaking of generations such as above-mentioned the 2nd driven wheel 15 and eccentric rod 21, become around about the shaking of front and back (x) (fluctuating) of (y) axis.And, also can be that seat 2 is with respect to pedestal 19 Rotate 180s °, installs on the contrary before and after promptly.Like this, the installation direction of seat 2 on head motion 3 suitably stipulated to get final product according to the purposes that this balance training 1 is required.

On the other hand, motor 24 makes gear 23 rotations, but with the shaking basic point and be pulled to the most close eccentric shaft 22a of this gear 23 all-in-one-piece eccentric shaft 22a and then above-mentioned eccentric rod 21 time, when eccentric rod 21 is positioned at bottom dead centre, and when at utmost being raised by eccentric shaft 22a, when eccentric rod 21 is positioned at top dead-centre, above-mentioned head motion 3 produces maximum deviation around above-mentioned rotation 11z.Like this, exist And have under the situation of above-mentioned reversing (deflection) composition, as Figure 28 and shown in Figure 29, the reference position of shaking changes to P0 ' from above-mentioned P0.Figure 28 is the situation that basic point is pulled to eccentric shaft 22 of shaking of eccentric rod 21, and head motion 3 is offset to the left.In contrast to this, Figure 29 is the situation that basic point is boosted by eccentric shaft 22a of shaking of eccentric rod 21, and head motion 3 is offset to the right.And, in θ=0 ° and do not have under the situation of above-mentioned reversing (deflection) composition, the axis that rocks back and forth among Figure 27 from Reference numeral V11 displacement to the left and right shown in V11 '.

Like this, the track of seat 2 is tilted around above-mentioned rotation 11z, the angle of oscillation about can making, about torsion angle, about directly advance amount of movement and can have difference in left side and right side.Like this, for example can locally strengthen pleural muscle tendon and adductor tendon etc., can strengthen muscle power efficiently, also can cultivate trainer's the sense of equilibrium.And, if motor 24 is rotated continuously, head motion 3 is changed continuously around the inclination of above-mentioned rotation 11z, make the moving picture variation, can realize the good balance training of continuous usability that the trainer can not be weary of.

Moreover, the profile of tooth of worm gear 13b also can be formed on the direction of rotation of motor 13 and driven

wheel

14,15 on a certain direction of turning right or turning left accordingly, but in the present embodiment, be formed on following direction, when to be seat 2 because of loading sink to (counter-rotating drives), scribe profile of tooth to this worm screw 13b in the direction of the direction that is pressed into above-mentioned output shaft 13a (the motor 13 directions) application of force from worm gear 14a.Like this, when seat 2 sank to because of body weight of trainer etc., worm screw 13b can not come off and this seat 2 is sharply descended from output shaft 13a.

Figure 30 is the block diagram of the electrical structure of expression balance training 1.Response is from the operation of aforesaid operations circuit board 9a, and aforementioned body lateral circuit plate 4r drives that mechanical mechanism that the seat inclination that is made of with motor 13, by d.c. motor etc. shaking of constituting such as DC brushless motor constitutes with motor 20d, by d.c. motor etc. tilts forward and back the motor 12d of (lifting) usefulness and by the tilt motor 24 of usefulness of the machinery that d.c. motor etc. constitutes.With respect to the tilt quantity of

head motion

3,20e detects the pedestal 19 (seat 2) that motor 20d by above-mentioned seat inclination usefulness produces by height detection unit.By above-mentioned mechanical mechanism tilt forward and back support unit 11 (head motion 3) that the motor 12d of (lifting) usefulness produces with respect to the tilt quantity of pillar 4b, be the above-mentioned tiltangle of rotation 11z, 12e detects by height detection unit.Tilt head motion 3 that the motor 24 of usefulness produces with respect to the tilt quantity of support unit 11 by above-mentioned mechanical mechanism, detected by encoder 26, its testing result is input to aforementioned body lateral circuit plate 4r.

Figure 31 is the block diagram of the electrical structure of expression main body side circuit board 4r.At first, power circuit 52, for example be transformed into the direct current of 140V, 100V, 15V, 12V and 5V, supply with each circuit in this main body side circuit board 4r from the commercial ac power of attaching plug 51 input.In this main body side circuit board 4r, come control action by control circuit 53 with microcomputer 53a, show output by operator drive circuit 54 to above-mentioned operator circuit board 9a, receive input simultaneously from operator circuit board 9a.Height detection unit 20e, the 12e that imports with the rotary angle position of motor 13 and rotary speed, by sensor drive driving circuit 56,57,58 to this input, by shaking of detection signal treatment circuit 55 input and the testing result of encoder 26 are replied, above-mentioned control circuit 53 drives by drive circuit 59 and shakes the motor 13 of usefulness, drives motor 20d, the 12d, 24 of inclination usefulness by drive circuit 60.

And, aspect driving, should be noted in the discussion above that shown in figure 32, if motor 12d changes the tiltangle of rotation 11z, then switch the direction of rotation of the motor 13 that shakes usefulness by control circuit 53.And, should be noted in the discussion above that shown in figure 32 control circuit 53 is controlled to rotary speed and reduces relatively according to the anglec of rotation of the motor of importing by detection signal treatment circuit 55 that shakes usefulness 13 when seat 2 rises; When seat 2 descends, rotary speed is accelerated relatively.

So, at first, change the direction of rotation of switching motor 13 accordingly, even the fore-and-aft direction that the constant transfer of trainer is sat by tiltangle with rotation 11z, also shaking under the retrograde orbit can be experienced, muscle generally obsolete, that lack exercise can be tempered.

And the rotary speed of shaking with motor 13 slows down when seat 2 rises, and accelerates when descending, and can suppress the torque capacity to motor 13 requirements like this, makes this motor 13 and then head motion 3 miniaturizations.And,,, can strengthen trainer's leg strength even identical stroke up and down also can increase stepping on the body weight load of the pin on stirrup 7 from the movement effects aspect.

Moreover, drive circuit 53 response is by the rotary angle position of the motor 13 of the sensor signal processing circuit 55 inputs, is that unit controls with the least common multiple of the gear ratio of the gear 15a of the gear 14b of above-mentioned the 1st driven wheel 14 and the 2nd driven wheel 15.Specifically, if above-mentioned gear ratio for example was made as 1.2: 2, then transfer 1 unit to 5 of the 1st driven wheel 14 and control, control circuit 53 will stop the energising of motor 13 according to the method that stops in its 5th moment of changeing end when stopping the energising of motor 13.For example, the lifting position at the 5th seat 2 that changes stops to power up.On the other hand, the inclination angle of the profile of tooth of worm screw 13b is set under the state that motor does not power up, for the loading input from coming as pedestal 19 sides of load, the angle that can reverse.

Owing to constitute like this, so as mentioned above, even the engagement of the 1st driven wheel 14 and the 2nd driven wheel 15 changes constantly, also can energising makes the 1st driven wheel 14 utilize seat 2 and trainer's etc. loading to reverse to motor 13 by stopping, when the 1st driven wheel 14 stops at this

eccentric shaft

14c, 14d and is positioned at bottom dead centre (0 ° or 180 °) (seat 2 sinks to, and stops on upper/lower positions).Here, the 2nd driven wheel 15 also stops on the position of 0 ° or 180 °, and seat 2 stops on the mid point.

By stopping at like this on the mid point, make the trainer easily about, the trainer is driven with correct posture, can carry out the good motion of balance.
