diaphragm support portion

4A and 4B.

As stated, chassis 70 makes its travel path receive the restriction of wheel 71 and track 72.Thereby chassis 70 is reciprocal along the length of track 72 along with worm gear 21b rotation.That is, the rotating tee of motor 20 crosses worm screw 21a and worm gear 21b passes to crankshaft cheek 22b, makes chassis 70 back and forth linear along track 72 so that be coupled to the toggle-action lever 22c of crankshaft cheek 22b.Thereby left foot and right crus of

diaphragm support portion

4A and 4B are driven reciprocal along the length of track 72 respectively.

In the present embodiment, worm screw 21a and two worm gear 21b are responsible for being separated to driving force in two passages that are respectively applied for driving left foot and right crus of

diaphragm support portion

4A and 4B, so that driver element 2 drives left foot and right crus of

diaphragm support portion

4A and 4B with the mode that links each other.Worm gear 21b engages with worm screw 21a in the different piece that separates with 180 °, so that right crus of diaphragm support portion 4B arrives the front end of its mobile range when left foot support portion 4A arrives the rear end of its mobile range.When right-hand member and the right crus of diaphragm support portion 4B that when it arrives the rear end of mobile range, arrives its mobile range along with left foot support portion 4A arrived the right-hand member of its mobile range when it arrives the front end of mobile range, left foot and right crus of

diaphragm support portion

4A and 4B transversely direction were mobile on direction equally.

Be apparent that according to above content, the expectation phase difference that moves between left foot and right crus of diaphragm support portion 4A and the 4B can be provided through the bonding station that changes worm gear 21b and worm screw 21a.When the user makes its pin be placed on the stance operative installations on left foot and right crus of diaphragm support portion 4A and the 4B; 180 ° phase difference is effectively for mobile the minimizing that makes user's weight on forward/backward direction, even make the user who reduced by balanced capacity also can take exercise.Can be as an alternative, when phase difference was not provided, device was necessary mobile subscriber's weight on forward/backward direction, thereby not only leg muscle was also carried out exercise to user's lower back muscle of keeping balanced capacity.

Mention along band, allow each the pin support portion in the pin support portion 4 to center on axle 48 rotations.Therefore, can change the rear end of bearing carrier 40 and the height and position of front end.Thereby, can change the heel that is placed on the pin on the bearing carrier 40 and the height and position of tiptoe, so that can realize the sole of the foot song and the dorsiflex of ankle-joint.Present embodiment adopts following structure to be linked oscillating motion and its reciprocating motion along track 72 of bearing carrier 40 around axle 48.That is, base plate 30 is provided with the guide surface (not shown) that comprises deflection in the part along the travel path of bearing carrier 40.In this connected, base 41 was provided with the servo-actuated protuberance (not shown) that engages with guide surface in its bottom.The servo-actuated protuberance has the roller bearing that rolls and contact with guide surface at its top.Though the servo-actuated protuberance has roller bearing, the servo-actuated protuberance is formed and/or be shaped to structure by material just enough to have the little tip of coefficient of friction.

In this case; Be arranged to drive in the pin support portions 4 each at drive motors 20 and the deflection of guide surface is raise and reduction in reciprocal with roll servo-actuated protuberance contact of guide surface; Thereby to change bearing carrier 40 and the angle of inclination of base 41, therefore make it possible to realize the sole of the foot song and the dorsiflex of ankle with respect to base plate 30 around axle 48 swing bases 41.

In the exercise aid device of present embodiment, control module 8 is configured to carry out control to drive unit 2 (to controling of the drive motors 20 of drive unit 2) and to the control of leaning device unit 6 (to controling of the adjustment motor 45c of leaning device unit 6).

Control module 8 is microcomputers for example.Control module 8 control offers the electrical power of adjustment motor 45c or drive motors 20 from the power source (not shown), thereby starts drive motors 20, closes down drive motors 20, or adjusts the revolution of drive motors 20.Further, control module 8 is configured to when the switch (not shown) that is provided with on the shell 3 is connected, start drive motors 20 and when switch turn-offs, close down drive motors 20.

Control module 8 further is configured to the adjustment motor 45c of leaning device unit 6 inclination of pulse power with adjustment bearing carrier 40 is provided from power source.

Control module 8 is adjusted the inclination of bearing carrier 40 with reference to the testing result of each load detecting unit 5.Control module 8 control leaning device unit 6 promptly, tilt bearing carrier 40, with two load sensor 50A of the detecting unit 5 that reduces to load and 50B poor between the detected load respectively.Especially; In the present embodiment; Control module 8 control leaning device unit 6 are about 0 (that is, the detected load of load sensor 50A becomes and equates with the detected load of load sensor 50B) so that the difference between two load sensor 50A and the detected respectively load of 50B becomes.

Therefore; In the exercise aid device of present embodiment; The load detecting unit 5, leaning device unit 6 and the control module 8 that comprise two load sensors 50 have constituted following this tilting gearing A: it is configured to make bearing carrier 40 to tilt, to reduce to load that the outside 40a of bearing carrier 40 applies and poor between the load that the inside of bearing carrier 40 40b applies.

Next, the operation of the exercise aid device of present embodiment is explained.Suppose that under initial situation switch maintenance shutoff and left foot and right crus of

diaphragm support portion

4A and 4B lay respectively at predetermined initial position.At initial position, left foot and right crus of

diaphragm support portion

4A and 4B are positioned at the same at along forward/backward direction.That is, left foot and right crus of

diaphragm support portion

4A and 4B are when they are in during at initial position on the line that transversely direction is extended.Correspondingly, when left foot and right crus of diaphragm support portion 4A and the 4B that stands in initial position when subscriber station went up, the vertical curve that dangles from user's center of gravity passed the center between left foot and right crus of diaphragm support portion 4A and the 4B.

As stated, the inclination of adjustment bearing carrier 40 equates with the detected load of load sensor 50B so that the detected load of load sensor 50A becomes.Therefore, under initial situation, only if user M is shelved on its pin on the pin support portion 4, otherwise the load-bearing surface of bearing carrier 40 almost keeps parallel with horizontal plane.

When user M is shelved on 4 last times of pin support portion to its pin, carry out operation as follows.

For example; The load that applies as the outside 40a to bearing carrier 40 surpasses the load that applies to the inside of bearing carrier 40 40b (promptly; Shown in Fig. 3 B; User M has rhaeboscelia) time, tilting gearing A tilts to promote outside 40a (that is, bearing carrier 40 being sloped inwardly) (seeing Fig. 3 B) with respect to inner 40b bearing carrier 40.Further, as stated, make bearing carrier 40 constantly tilt, become till zero up to the difference between two load sensor 50A and the detected respectively load of 50B.When the outside 40a of bearing carrier 40 is thus lifted to the position that is higher than inner 40b; The load that applies to the inboard of lower limb is increased to than the pin the user and makes its width keep bigger degree under the situation of parallel with horizontal plane (that is, the load-bearing surface of bearing carrier 40 is in the horizontal plane).Correspondingly, inboard that can the intensive training lower limb muscles.Do not need the difference between the strict load limited to remain 0.Difference between the load keeps being about 0 just enough.

Simultaneously; When the load that applies to the inside of bearing carrier 40 40b surpasses the load that applies to the outside 40a of bearing carrier 40 (promptly; User M has in knee) time, tilting gearing A tilts to promote inner 40b (that is, make bearing carrier 40 outward-dipping) with respect to outside 40a bearing carrier 40.Further, as stated, make bearing carrier 40 keep tilting, become till zero up to the difference between two load sensor 50A and the detected respectively load of 50B.When promoting the inside 40b of bearing carrier 40 with respect to outside 40a, the load that applies to the outside of lower limb keeps the situation increase with horizontal direction parallel (the load-bearing surface maintenance of bearing carrier 40 is parallel with horizontal plane) than the pin width.Correspondingly, the outside that can the intensive training lower limb muscles.Do not need the difference between the strict load limited to remain 0.Difference between the load keeps being about 0 just enough.

When the load that applies to the inside of bearing carrier 40 40b when load that outside 40a to bearing carrier 40 applies equates (that is, it is in knee that user M had not both had rhaeboscelia not have yet), tilting gearing A does not make bearing carrier 40 tilt.

Connect switch exercise aid device is operated just enough from initial situation.When switch connection, control module 8 provides electrical power to start drive motors 20 to drive motors 20.When drive motors 20 started, drive motors 20 can drive left foot and right crus of

diaphragm support portion

4A and 4B respectively, on the direction different with the length direction of pin, to move.For example, left foot and right crus of

diaphragm support portion

4A and 4B move through the for example travel distance of 20mm on the direction of forward/backward direction with 45 ° angular deflection with respect to shell 3.

Further, drive bearing carrier 40 and base 41 along with left foot and right crus of

diaphragm support portion

4A and 4B back and forth swing around spools 48 along track 72 separately.When bearing carrier 40 moved, the servo-actuated protuberance raise the deflection of guide surface and reduces, thereby when left foot and right crus of

diaphragm support portion

4A and 4B arrive its front position separately, caused the dorsiflex of ankle-joint, and when its arrival position, its rear end, made the ankle plantar song.Be positioned near heel in axle 48 length under foot.Each in dorsiflex and the sole of the foot song realized at the about 10 ° angle of inclination of reference planes so that the upper surface with respect to base plate 30 limits.Can carry out the dorsiflex and sole of the foot song respectively by tying up to left foot and right crus of

diaphragm support portion

4A and 4B back-end location and front position separately with above opposite pass.In addition, can select the angle of inclination with respect to reference planes different with above-mentioned angle.Can easily realize the operation of this modification through suitably shaped guide surface.

The exercise aid device of present embodiment makes user M carry out passive exercise by means of moving left foot and right crus of

diaphragm support portion

4A and 4B as stated.

As stated,, bearing carrier 40 is tilted, to reduce to load that the outside 40a of bearing carrier 40 applies and poor between the load that the inside of bearing carrier 40 40b applies according to the exercise aid device of present embodiment.Therefore; The load that applies at the outside 40a to bearing carrier 40 surpasses the load that applies to the inside of bearing carrier 40 40b (promptly; The user has rhaeboscelia) time, the load that applies to the inboard of lower limb is increased to than the pin the user and makes bigger degree under its width maintenance situation parallel with horizontal plane.Correspondingly, inboard that can the intensive training lower limb muscles.Simultaneously; At the load that applies to the inside of bearing carrier 40 40b (promptly above the load that applies to the outside 40a of bearing carrier 40; The user has in knee) time, the load that applies to the outside of lower limb is increased to than the pin the user and makes bigger degree under its width maintenance situation parallel with horizontal plane.Correspondingly, the outside that can the intensive training lower limb muscles.Thereby, even have under rhaeboscelia or the situation in knee, also can improve the outside and the balance between the inboard (can force unbalance) of lower limb muscles the user.As a result, can treat the distortion bone (that is, can recover the bone alignment of lower limb) of lower limb.Further, the user can alleviate knee pain when enjoying comfortable passive exercise (training), also can carry out passive exercise even this means the user who in its walking process, suffers knee pain.

Further, owing to detect load that applies to the outside 40a of bearing carrier 40 and the load that applies to the inside of bearing carrier 40 40b, so can accurately estimate the distortion of user's lower limb.Control module is configured to control leaning device unit 6 reducing two

load sensor

50A and 50B poor between the detected load respectively, thereby makes bearing carrier 40 inside or outward-dipping.Therefore, can be paired in user M to the tilt adjustments of bearing carrier 40 and stark right inclination.

Notice that the configuration of leaning device unit 6 is not limited to above example.For example; Can adopt of the configuration of following this conventional arrangement as leaning device unit 6: as, the linear moving mechanism of electric rotating machine and feed screw group, electric rotating machine and belt group, electric rotating machine and pantogragh (pantograph) mechanism group, the linear moving mechanism that uses magnetic plug and use air bag.

In above embodiment, separated part 21 is configured to have worm gear 21b and worm screw 21a, is used under the situation that speed reduces realizing the power transmission from the output shaft 20a of drive motors 20 to the rotating shaft 21c of worm gear 21b.Yet, can use belt to pass to the rotating shaft 21c vertical to power from the output shaft 20a of drive motors 20 with output shaft 20a.In this example, use pulley but not worm gear 21b accepts belt has saved worm screw 21a simultaneously.

In above embodiment, drive motors 20 makes its output shaft 20a extend along the upper surface of base plate 30.Yet, when output shaft 20a need extend perpendicular to the upper surface of base plate 30, adopt transmission that spur gear realizes rotary power and separate, but not the combination of worm screw 21a and worm gear 21b.In this example, can use pulley and belt to substitute spur gear to be used between pulley, transmitting rotary power.

Replace and use crankshaft cheek 22a and toggle-action lever 22c, reciprocating part 22 can comprise by the grooved cam of drive motors 20 driven in rotation and be bonded on the cam-follower in the cam path.In this example, can use grooved cam to replace worm gear 21b, and grooved cam is arranged to make its rotating shaft parallel with the output shaft 20a of drive motors 20, to be used for through pinion from output shaft 20a to the grooved cam transmitted power.

Further; When only using a grooved cam to be used for power to transmit from the output shaft 20a of drive motors 20 to grooved cam; Two cam-followers can be used for engaging with the cam path of cam respectively, so that grooved cam and cam-follower are jointly as separated part 21 and reciprocating part 22.

Though the embodiment that illustrates has base plate 30 that is formed with guide surface and the base 41 that is formed with the servo-actuated protuberance; But can adopt following this configuration to realize same operation: wherein, base 41 is provided with guide surface and base plate 30 is provided with the servo-actuated protuberance.

Because the exercise aid device of present embodiment comprises load detecting unit 5, so exercise aid device is provided with the inclination of bearing carrier 40 automatically.Yet load detecting unit 5 is optional.That is, exercise aid device can be configured to make that the user can be based on the inclination of situation (for example, arc pin or in knee) the manual adjustment bearing carrier 40 of its pin.In this example, the operating unit (not shown) that is provided for operating leaning device unit 6 for shell 3 is just enough.

Be placed on the floor though the exercise aid device of present embodiment is configured to be applicable to, exercise aid device can be partially submerged under the situation in the floor at it and use.Selection is in the placement of place, fixed position or movably supports exercise aid device.These aspects can be applied to the exercise aid device of following second embodiment.

(second embodiment)

The exercise aid device of present embodiment is different with the exercise aid device of first embodiment aspect the configuration of tilting gearing A.Other assembly of the exercise aid device of present embodiment is the same with first embodiment.Therefore, other assembly marks out and saves its repeat specification by identical Reference numeral.

In the tilting gearing A of present embodiment, shown in Fig. 4 A to Fig. 4 C, load detecting unit 5 comprises the load sensor 50 that is configured to detect the load that applies to the inside of bearing carrier 40 40b.In brief, different with the load detecting unit 5 of first embodiment, the load detecting unit 5 of present embodiment includes only a load sensor 50.

The control module 8 of present embodiment is configured to control leaning device unit 6 based on a load sensor 50 detected loads.Control module 8 is configured to comparison load sensor 50 detected load and predetermined thresholds, and based on relatively confirming of drawing to load that the outside 40a of bearing carrier 40 applies and poor between the load that the inside of bearing carrier 40 40b applies.Predetermined threshold is the load that for example applies to inner 40b under the situation that the outside 40a and the inner 40b of bearing carrier 40 apply same load at user M.In this example, poor through between predetermined threshold and the load sensor 50 detected loads confirmed to load that outside 40a applies and poor between the load that inner 40b applies.Note, can be according to the body wt estimation predetermined threshold of user M.To put exercise aid device just enough as long as the user adds own wt when prepare using exercise aid device.In addition, can estimate predetermined threshold according to the detected load of load sensor of the load detecting unit 5 of each pin support portion 4.

Control module 8 not only has predetermined threshold and also has judgment value as the value that will compare with load sensor 50 detected loads.Judgment value is to be used for judges M whether to be shelved on the value on the pin support portion 4 to its pin.Control module 8 is configured to judge that when load sensor 50 detected loads user M is not shelved on its pin on the pin support portion 4 during less than judgment value.In this case, control module 8 control leaning device unit 6, parallel so that the load-bearing surface of pin support portion 4 bearing carrier 40 separately keeps with horizontal plane.

The control module 8 of present embodiment provides the inclination of pulse power with adjustment bearing carrier 40 from power source to the adjustment motor 45c of leaning device unit 6, thereby reduces to load that outside 40a applies and poor between the load that inner 40b applies.As stated; Threshold value for user M under the situation that the outside 40a and the inner 40b of bearing carrier 40 apply same load in the situation of the load that inner 40b applies; Control module 8 makes bearing carrier 40 deflections, so that load sensor 50 detected loads become equates with threshold value.

In the exercise aid device of present embodiment, load detecting unit 5, leaning device unit 6 and control module 8 have constituted tilting gearing A.

Next, the operation of the exercise aid device of present embodiment is explained.

Under initial situation, only if user M is shelved on its pin on the pin support portion 4, otherwise load sensor 50 detected loads are less than judgment value.Control module 8 control leaning device unit 6 are so that the load-bearing surface of bearing carrier 40 keeps parallel with horizontal plane (seeing Fig. 4 A).

When user M is shelved on 4 last times execution following operation in pin support portion to its pin.

For example; The load that applies as the outside 40a to bearing carrier 40 surpasses when the load that the inside of bearing carrier 40 40b applies; Tilting gearing A makes bearing carrier 40 deflections to rise to outside 40a the position (that is, making bearing carrier 40 toe-ins) (seeing Fig. 4 B) that is higher than inner 40b.As stated, make bearing carrier 40 constantly tilt, become till zero up to the difference between threshold value and the load sensor 50 detected loads.When the outside 40a of bearing carrier 40 is thus lifted to the position that is higher than inner 40b; The load that applies to the inboard of lower limb is increased to than the pin the user and makes its width keep bigger degree under the situation of parallel with horizontal plane (that is, the load-bearing surface of bearing carrier 40 is in level).Correspondingly, inboard that can the intensive training lower limb muscles.

Simultaneously; When the load that applies to the inside of bearing carrier 40 40b surpasses to load that the outside 40a of bearing carrier 40 applies; Tilting gearing A makes bearing carrier 40 deflections to rise to inner 40b the position that is higher than outside 40a (that is, make bearing carrier 40 outward-dipping) (seeing Fig. 4 C).As stated, make bearing carrier 40 constantly tilt, become till zero up to the difference between threshold value and the load sensor 50 detected loads.When 40b is thus lifted to the position that is higher than outside 40a in the inside of bearing carrier 40; The load that applies to the outside of lower limb is increased to than the pin the user and makes bigger degree under its width maintenance situation of parallel with horizontal plane (that is, the load-bearing surface of bearing carrier 40 keeps parallel with horizontal plane).Correspondingly, the outside that can the intensive training lower limb muscles.

When the load that applies to the inside of bearing carrier 40 40b when load that outside 40a to bearing carrier 40 applies equates, tilting gearing A does not make bearing carrier 40 deflections (seeing Fig. 4 A).

User M can carry out above-mentioned passive exercise through after being shelved on the pin support portion 4 respectively, connecting switch to its pin.

Above-mentioned exercise aid device according to present embodiment; Identical with the exercise aid device of first embodiment; Bearing carrier 40 is tilted, to reduce to load that the outside 40a of bearing carrier 40 applies and poor between the load that the inside of bearing carrier 40 40b applies.Therefore, inboard that can the intensive training lower limb muscles when the user has rhaeboscelia.Further, when the user have when in knee can the intensive training lower limb muscles the outside.Thereby, even have under rhaeboscelia or the situation in knee the user, also can improve the outside and the balance between the inboard of lower limb muscles or treat between the lower limb muscles outside and the inboard can force unbalance.As a result, can treat the distortion bone (that is, can recover the bone alignment of lower limb) of lower limb.Further, the user can alleviate knee pain when enjoying comfortable passive exercise (training), also can carry out passive exercise even this means the user who in its walking process, suffers knee pain.

Further, the load sensor 50 detected loads based on load detecting unit 5 make bearing carrier 40 with respect to the inside or outside deflection of user's pin.Therefore, can be paired in the user to the tilt adjustments of bearing carrier 40 and stark right inclination.It should be noted that according to present embodiment, because the quantity of the load sensor 50 of load detecting unit 5 can be reduced to one, so can reduce production cost.

In above-mentioned example, though load sensor 50 is configured to detect the load that applies to inner 40b, load sensor 50 can be configured to detect the load that applies to outside 40a.In this example, predetermined threshold can be the load that under the situation that the outside 40a and the inner 40b of bearing carrier 40 apply same load, applies to outside 40a at user M.Leaning device unit 6 makes the bearing carrier deflection so that load sensor 50 detected loads become to be equated with threshold value though the control module 8 of above-mentioned example is configured to control, and the control module 8 of another example is configured to change with step-by-step system the angle of inclination of bearing carrier 40.For example, when load sensor 50 detected loads were not less than first threshold, control module 8 made bearing carrier 40 outside deflections with predetermined angular with respect to the horizontal plane.When load sensor 50 detected loads were not more than second threshold value, control module 8 made bearing carrier 40 toe-ins with predetermined angular with respect to the horizontal plane.When load sensor 50 detected loads surpass second threshold value and during less than first threshold, control module 8 keeps bearing carriers 40 levels.

Mention that along band Fig. 5 A to Fig. 5 C shows the exercise aid device of another embodiment of the present invention.Exercise aid device shown in Fig. 5 is different with the exercise aid device of the exercise aid device shown in Fig. 4 and first embodiment aspect the configuration of pin support portion 4.Other assembly of exercise aid device shown in Fig. 5 is the same with the exercise aid device of the exercise aid device shown in Fig. 4 and first embodiment.Therefore, other assembly marks out and saves its repeat specification by identical Reference numeral.

Pin support portion 4 shown in Fig. 5 is provided with a pair of air bag (air chamber) 60 that is configured to limit distance between bearing carrier 40 and the base 41.The form of air bag 60 is the same.Air bag 60 is in order to having carried the outside 40a of bearing carrier 40, and another air bag 60 is in order to have carried the inside 40b of bearing carrier 40.Therefore, bearing carrier 40 deflections when an air bag 60 expands with respect to another air bag 60 or shrinks.In brief, the exercise aid device shown in Fig. 5 has the leaning device unit 6 that comprises a pair of air bag 60.In addition, shell 3 is configured to hold the air pump (not shown) that each air bag that is configured in air bag 60 provides air.Further, the opposite end of base 41 on its width is provided with adjustment means 41b.Adjustment means 41b is configured to limit the scope that allows bearing carrier 40 to tilt.

Air bag 60 is provided with the valve member (not shown).Valve member is configured to the exhaust outlet 60a of closed airbag 60, till air bag 60 pressure inside surpass predetermined value.Predetermined value is selected such that air pump can provide enough air to air bag 60, and is parallel with horizontal plane so that the load-bearing surface of the bearing carrier 40 of pin support portion 4 keeps.In other words, predetermined value is to carry bearing carrier 40 so that load-bearing surface keeps the air bag 60 parallel with horizontal plane not spray the value under the situation of gas.

The outside 40a of the bearing carrier 40 shown in Fig. 5 and each among the inner 40b are provided with retainer 40c.The through hole 40d of air bleeding valve 49 extends through bearing carrier 40 parts relative with retainer 40c on its thickness direction.Air bleeding valve 49 forms following this L shaped: it comprises and is configured to guard the valve portion 49a of exhaust outlet 60 and on valve portion 49a, forms with the load test section 49b from valve portion 49a horizontal expansion with integral way.Valve portion 49a penetrated through via holes 40d.Air bleeding valve 49 is applicable to the exhaust outlet 60a that forces closed airbag 60.

Elastic component 51 is inserted between the load test section 49b of bearing carrier 40 and air bleeding valve 49.Elastic component 51 is processed by the elastomeric material such as rubber, when bearing the load that is not less than setting, to shrink.When the load that applies to elastic component 51 was not more than setting, elastic component 51 remained on the position that air bleeding valve 49 is opened exhaust outlet 60a to air bleeding valve 49.Comparatively speaking, when the load that applies to elastic component 51 surpassed setting, elastic component 51 shrank, and moved to the position of air bleeding valve 49 sealing exhaust outlets 60 to allow air bleeding valve 49.Setting is to be slightly less than the load that under the situation that the outside 40a and the inner 40b of bearing carrier 40 apply same load, applies to outside 40a (or inner 40b) at user M (value).Notice that elastic component 51 can have known configuration, therefore, there is no need it is elaborated.

In the example shown in Fig. 5 A to Fig. 5 C, air bag 60, air bleeding valve 49 and elastic component 51 have constituted tilting gearing A.In following explanation; In order to distinguish air bag 60, air bleeding valve 49 and the elastic component 51 corresponding and air bag 60, air bleeding valve 49 and the elastic component 51 corresponding respectively with inner 40b with outside 40a; As required; For the Reference numeral of each in the air bag corresponding with outside 40a 60, air bleeding valve 49 and the elastic component 51 adds suffix " A ", and be each Reference numeral interpolation suffix " B " in air bag 60, air bleeding valve 49 and the elastic component 51 corresponding with inner 40b.

Next, the operation of the exercise aid device shown in Fig. 5 is explained.Under initial situation, air pump provides air to each air bag 60, and is parallel with horizontal plane so that the load-bearing surface of bearing carrier 40 keeps.Under initial situation, the exhaust outlet 60a of valve member closed airbag 60 before user M is shelved on its pin on the pin support portion 4.Therefore, shown in Fig. 5 A, a pair of air bag 60 has carried bearing carrier 40, and is parallel with horizontal plane so that load-bearing surface keeps.

When user M is shelved on 4 last times of pin support portion to its pin, carry out operation as follows.For example, when the load that applies as the outside 40a to bearing carrier 40 equated with the load that applies to the inside of bearing carrier 40 40b,

air bag

60A and 60B valve member separately was at the corresponding exhaust outlet 60a of much the same time opening.After its inside ejection air,

elastic component

51A and 51B begin to shrink in much the same timing at air bag 60.Therefore,

air bleeding valve

49A and 49B be enclosed in much the same time opening,

air bag

60A and 60B exhaust outlet 60a separately.As a result, bearing carrier 40 is deflection not, and load-bearing surface keeps parallel with horizontal plane.

The load that applies as the outside 40a to bearing carrier 40 surpasses when the load that the inside of bearing carrier 40 40b applies, and each sprays gas since it is inner air bag 60A and 60B.Yet elastic component 51A shrank before elastic component 51B shrinks.That is the exhaust outlet 60a of air bag 60A sealing before the exhaust outlet 60a of air bag 60B sealing.As a result, air bag 60A is used for keeping the outside 40a of bearing carrier 40 and base 41 to separate constant distance (seeing Fig. 5 B).This makes the load that applies to inner 40b increase, and makes that thereupon elastic component 51B begins to shrink.Therefore, the exhaust outlet 60a of air bag 60B sealing, and air bag 60B is used for keeping the inside 40b of bearing carrier 40 and base 41 to separate constant distance (seeing Fig. 5 C).When air bag 60A and 60B exhaust outlet 60a separately seal as stated; Make the air bag 60A of its exhaust outlet 60a sealing before the exhaust outlet 60a of air bag 60B sealing keep the air capacity bigger than air bag 60B, wherein the exhaust outlet 60a of air bag 60B seals with rear enclosed at the exhaust outlet 60a of air bag 60A.As a result, make between base 41 and the bearing carrier 40 distance towards outside 40a place greater than at inner 40b place.In brief, bearing carrier 40 is with respect to the pin toe-in of user M.

When the load that applies to the inside of bearing carrier 40 40b surpassed to load that the outside 40a of bearing carrier 40 applies, each sprayed gas since it is inner air bag 60A and 60B.Yet elastic component 51B shrank before elastic component 51A shrinks.That is the exhaust outlet 60a of air bag 60B sealing before the exhaust outlet 60a of air bag 60A sealing.As a result, air bag 60B is used for keeping the inside 40b of bearing carrier 40 and base 41 to separate constant distance.This makes the load that applies to outside 40a increase, and makes that thereupon elastic component 51A begins to shrink.Therefore, the exhaust outlet 60a of air bag 60A sealing, and air bag 60A is used for keeping the outside 40a of bearing carrier 40 and base 41 to separate constant distance.When air bag 60A and 60B exhaust outlet 60a separately seal as stated; Make the air bag 60B of its exhaust outlet 60a sealing before the exhaust outlet 60a of air bag 60A sealing keep the air capacity bigger than air bag 60A, wherein the exhaust outlet 60a of air bag 60A seals with rear enclosed at the exhaust outlet 60a of air bag 60B.As a result, make between base 41 and the bearing carrier 40 distance towards inner 40b place greater than 40a place externally.In brief, bearing carrier 40 is with respect to the outside deflection of the pin of user M.

Be apparent that according to above content the exercise aid device shown in Fig. 5 A to Fig. 5 C can make bearing carrier 40 tilt, to reduce to load that the outside 40a of bearing carrier 40 applies and poor between the load that the inside of bearing carrier 40 40b applies.Therefore, can improve the outside and the balance between the inboard (ability force unbalance) of lower limb muscles.As a result, can treat the distortion bone (that is, can recover the bone alignment of lower limb) of lower limb.Further, the user can alleviate knee pain when enjoying comfortable passive exercise (training), also can carry out passive exercise even this means the user who in its walking process, suffers knee pain.In addition, because the circuit of load detecting unit 5 grades is unnecessary, so can reduce production cost.

Though the bearing carrier 40 of the exercise aid device shown in Fig. 5 A to Fig. 5 C is a plate, for example, can shown in Fig. 6 A, on its width, be divided into two to bearing carrier 40.Exercise aid device shown in Fig. 6 A has and the similar basic structure shown in Fig. 5.Therefore, same section marks and saves its repeat specification by identical Reference numeral.

In the example shown in Fig. 6 A, bearing carrier 40 is divided into outside 40a that forms rectangular slab and the inside 40b that forms rectangular slab.Outside 40a and inner 40b be respectively through using sloping shaft 43 and inclination bearing 44, on its width with rotation mode be coupled to base 41 in the sidewall sections 42 that is provided with in the heart.Correspondingly, in the example shown in Fig. 6 A, outside 40a and inner 40b be deflection independent of one another.

In the example shown in Fig. 6 A, air bag 60, air bleeding valve 49 and elastic component 51 have constituted tilting gearing A.

Above-mentioned configuration about dividing bearing carrier 40 can be applied to the example shown in Fig. 4 and first embodiment.In brief, tilting gearing A can be configured to make at least a portion of bearing carrier 40 to tilt, to reduce to load that the outside 40a of bearing carrier 40 applies and poor between the load that the inside of bearing carrier 40 40b applies.Bearing carrier 40 is not limited to above-mentioned example, and can be configured to change load and the balance between the load that the inside of bearing carrier 40 40b applies to the outside 40a of bearing carrier 40 applies.

Above-mentioned example shown in Fig. 5 and Fig. 6 has utilized the contraction of air bag 60, so that bearing carrier 40 deflections.Further, another example can be configured to the control air pump provides air so that its expansion to air bag 60, thereby makes bearing carrier 40 deflections.

In the example shown in Fig. 6 B, retainer 40c lays respectively at the back lower face of the outside 40a and the inner 40b of bearing carrier 40, and is coupled to sloping shaft 43 with rotation mode together with outside 40a and inner 40b respectively.The outside 40a of bearing carrier 40 and inner 40b are formed with the protruding 40e as the valve of exhaust outlet 60a respectively.Elastic component 51 is inserted in (not shown elastic component 51 among Fig. 6 B) between each among retainer 40c and outside 40a and the inner 40b.Elastic component 51 is configured to when the load that affords greater than predetermined load, shrink so that protruding 40e sealing exhaust outlet 60a.Predetermined load equates with the load that under the situation that the outside 40a and the inner 40b of bearing carrier 40 apply same load, applies to outside 40a (or inner 40b) at user M.

Further, in the example shown in Fig. 6 B, air bag 60 is inserted between retainer 40c and the base 41.Each air bag 60 has the air supply opening 60b that is connected to above-mentioned air pump.Air pump is configured to each air bag 60 air (pressurization) is provided; So that keep comparably when the outside 40a of bearing carrier 40 and inner 40b apply load at user M, the outside 40a of bearing carrier 40 keeps parallel with horizontal plane with inner 40b load-bearing surface separately.

Next, the operation of the exercise aid device shown in Fig. 6 B is explained.When user M is shelved on 4 last times of pin support portion to its pin; And the load that ought apply to the outside 40a of bearing carrier 40 equates (promptly with the load that applies to the inside of bearing carrier 40 40b; It is in knee that the user had not both had rhaeboscelia not have yet) time,

elastic component

51A and 51B do not shrink.Therefore,

air bag

60A and 60B exhaust outlet 60a does not separately seal.In this case, pressurize through air pump and keep outside 40a parallel with horizontal plane with inner 40b load-bearing surface separately.

The load that applies as the outside 40a to bearing carrier 40 surpasses when the load that the inside of bearing carrier 40 40b applies, and elastic component 51A shrank before elastic component 51B shrinks.That is the exhaust outlet 60a of air bag 60A sealing before the exhaust outlet 60a of air bag 60B sealing.Therefore, air bag 60A is along with providing air from air pump and expand, thus the outside 40a of lifting.This makes load of applying to inner 40b (that is, the load that applies to elastic component 51B) increase, thereby elastic component 51B is shunk.The contraction of elastic component 51B makes the exhaust outlet 60a of air bag 60B seal.This makes the load that applies to elastic component 51A reduce, thereby opens the exhaust outlet 60a of air bag 60A.In this case, air bag 60A expands along with air bag 60B and shrinks.Thereby, thereby being lifted the feasible load that applies to inner 40b, reduces inner 40b.As a result, the load that applies to outside 40a increases, thereby makes the exhaust outlet 60a sealing of air bag 60A and the exhaust outlet 60a of air bag 60B open.Alternately the repetition aforesaid operations is responsible for making each deflection among outside 40a and the inner 40b, so that the load that applies to outside 40a becomes equates with the load that applies to inner 40b.Even when the load that applies to the inside of bearing carrier 40 40b surpassed to load that the outside 40a of bearing carrier 40 applies, exercise assisting apparatus was also operated as stated in a similar manner.

Be apparent that according to above content the exercise aid device shown in Fig. 6 B can make bearing carrier 40 tilt, to reduce to load that the outside 40a of bearing carrier 40 applies and poor between the load that the inside of bearing carrier 40 40b applies.Therefore, can improve the outside and the balance between the inboard (ability force unbalance) of lower limb muscles.As a result, can treat the bone distortion (that is, can recover the bone alignment of lower limb) of lower limb.Further, the user can alleviate knee pain when enjoying comfortable passive exercise (training), also can carry out passive exercise even this means the user who in its walking process, suffers knee pain.In addition, because the circuit of load detecting unit 5 grades is unnecessary, so can reduce production cost.

Technical characterictic of the present invention can be applied to the exercise aid device shown in Fig. 7 A and Fig. 7 B.

Exercise aid device shown in Fig. 7 comprises the carriage 30 that will be placed on the precalculated position (like, floor).Carriage 30 is provided with support component 32 and handlebar 33.Support component 32 is provided with the seat 9 that is configured to carry user M buttocks in the top.Handlebar 33 has and is applicable to the handle 33a of user M held as required.A pair of pin support portion 4 invests carriage 30 and between support component 32 and handlebar 33.This pin support portion 4 has and the same configuration in the pin support portion of first embodiment 4 or Fig. 4 to Fig. 6 pin support portion 4 separately.In the exercise aid device shown in Fig. 7, a pair of pin support portion 4 has constituted support unit 1 together with seat 9.

Support component 32 is provided with the drive unit 2 that is configured to make seat 9 reciprocal.Drive unit 2 is configured to through using the drive source (not shown) to make as the seat 9 of the part of support unit 1 reciprocal, thereby is shelved on the pin support portion 4 respectively and its buttocks is shelved on the buttocks displacement that makes user M under the situation on the seat 9 at its pin.In brief, drive unit 2 is configured to change the weight that acts on user M shank.Drive unit 2 makes the buttocks displacement of user M, thereby changes the ratio of carrying user's weight between seat 9 and the pin support portion 4.The result is that drive unit 2 changes the user's weight that acts on buttocks, thereby changes the weight that acts on each pin of user.

Angle at knee remains under the situation of predetermined angular, and the load that applies to the femur zone of user M carries the ratio minimizing of user's weight along with seat 9 and increases.This is similar and can cause femoral muscle and tighten up with crooked user's self the knee of squatting down in the exercise process.That is, the vibration of seat 9 causes passive exercise but not the initiative exercise of user M.According to this passive exercise, femoral muscle repeats nervous and lax.Therefore, user M can be mainly performs physical exercise to self femoral muscle.

Be apparent that according to above content the exercise aid device shown in Fig. 7 can make bearing carrier 40 tilt, to reduce to load that the outside 40a of bearing carrier 40 applies and poor between the load that the inside of bearing carrier 40 40b applies.Therefore, even have under rhaeboscelia or the situation in knee, also can improve the outside and the balance between the inboard (can force unbalance) of lower limb muscles the user.As a result, can treat the distortion bone (that is, can recover the bone alignment of lower limb) of lower limb.Further, the user can alleviate knee pain when enjoying comfortable passive exercise (training), also can carry out passive exercise even this means the user who in its walking process, suffers knee pain.
