The exercise assisting device 1 includes a seat 10, a backrest 51, a base portion 53, a controller 54, and a pair of armrests 52. The seat 10 functions to support the buttocks and thighs. The seat portion 10 is provided on, for example, a base portion 53. The function of the arm rest 52 is to support the elbow. The pair of armrests 52 are provided on, for example, the sides of the seat 10, and are attached to the seat 10. The pair of armrests 52 are, for example, shaped such that, in the front-rear direction of the seat section 10, the upper portions thereof protrude forward and the lower portions thereof are retracted rearward. The base portion 53 is provided on the installation surface. By inputting information relating to the operation of the exercise assisting device 1 to the controller 54, the controller 54 outputs the information to a control device (for example, the control unit 500 in fig. 15) for controlling the operation of the exercise assisting device 1. The controller 54 is disposed on, for example, a handrail 52. One example of controller 54 is a plurality of keys or a touch panel display.

The backrest 51 is provided behind the seat 10. The backrest 51 includes a backrest main body 51A and a support member 51B. The backrest main body 51A functions to support the back. The backrest main body 51A is attached to the support member 51B. The support member 51B functions to support the backrest main body 51A. The support member 51B is attached to, for example, the seat 10.

The exercise assisting device 1 further includes a pair of back airbags 61 and a pair of holding airbags 62. The pair of rear airbags 61 are provided in the backrest main body 51A. The respective back airbags 61 stretch the back by repeating expansion and contraction, and stretch the back by maintaining the state in which the respective back airbags 61 are expanded. A retaining airbag 62 is provided, for example, on the inside face in a handrail 52. The other holding airbag 62 is provided on an inner surface of the other armrest 52, for example. By maintaining the inflated state of each holding airbag 62, the legs, pelvis, and the like are sandwiched between the holding airbags 62 and the seat 10, and the position of the body with respect to the seat 10 is held.

The exercise assisting device 1 further includes a driving portion 70. The driving portion 70 functions to swing the seat portion 10. The drive unit 70 is provided in the base unit 53, for example, and supports the seat unit 10 to be swingable. The seat 10 is swung by driving the driving unit 70. The backrest 51 and the pair of armrests 52 swing along with the swing of the seat 10. The backrest 51 and the pair of armrests 52 may be attached to the base portion 53 so as not to swing when the seat portion 10 swings.

The seat 10 has a plurality of forms, and any one of the plurality of forms is selected by deformation. The plurality of configurations include a 1 st configuration in which a user can sit and a 2 nd configuration in which a user can straddle. The sitting in the 1 st form is a posture that the user takes when the exercise assisting device 1 is used as in a general chair. The exercise assisting device 1 shown in fig. 1 is the 1 st embodiment.

The seat portion 10 includes an intermediate portion 11, a rear surface support portion 13, a switching portion 20 (see fig. 4), and a pair of side portions 12. The intermediate portion 11 is provided at an intermediate position in the width direction of the seat portion 10. The intermediate portion 11 is a portion that mainly supports the buttocks when the user 100 is seated in the 1 st configuration. The pair of side portions 12 are provided, for example, on both sides of the intermediate portion 11 in the width direction of the seat 10 so as to be rotatable about an axis along the front-rear direction of the seat 10. The pair of side portions 12 are portions that mainly support thighs when the user 100 is seated in the 1 st configuration.

In the example shown in fig. 1, the seating surface 10A in the 1 st form is formed into a substantially flat surface on which the user 100 can sit. The plane constituted by the seat surface 10A is a plane that does not make the user 100 seated on the seat 10 feel uncomfortable when the user 100 uses the exercise assisting device 1 as in a general chair. In one example, the seat 10 is configured as the 1 st form by operating at least one of the intermediate portion 11 and the pair of side portions 12 so as to reduce the difference between the height of the intermediate portion 11 and the height of the pair of side portions 12.

The back support portion 13 functions to support the waist. The rear support portion 13 is provided rearward of the intermediate portion 11. The height of the rear support portion 13 is lower than that of the backrest 51.

The intermediate portion 11 includes a front portion 11A and a rear portion 11B. The front portion 11A is a portion sandwiched between the pair of side portions 12. The front portion 11A is configured to be able to sandwich the front portion 11A with the thighs of both legs when the user 100 straddles the seat portion 10 in the 2 nd embodiment. The rear portion 11B is continuous with the front portion 11A and is provided rearward of the pair of side portions 12. The width of the intermediate portion 11 becomes narrower from the rear side to the front side of the seat portion 10. Therefore, the width of the front portion 11A is narrower than the width of the rear portion 11B. In one example, the front portion 11A is tapered such that the width thereof becomes narrower from the rear side to the front side of the seat portion 10.

Fig. 2 shows the movement aid 1 seen through the armrest 52. As shown in the figure, the front portion 11A bulges upward from the rear portion 11B. Specifically, the seat surface 10A of the front portion 11A bulges upward relative to the side portions 12, and the seat surface 10A of the rear portion 11B is recessed downward relative to the side portions 12.

Fig. 3 is an external appearance of the exercise assisting device 1 according to the 2 nd embodiment. The seat 10 is deformed to the 2 nd form by relatively operating the intermediate portion 11 and the pair of side portions 12 so that the intermediate portion 11 is higher than the pair of side portions 12 from the state of the 1 st form. When the exercise assisting device 1 adopts the 2 nd form, the pair of side portions 12 assume a posture inclined downward toward the outer side in the width direction of the seat portion 10. In the example shown in fig. 3, the seat surface 10A in the 2 nd form is configured to resemble a horse back or a saddle so that the user 100 can straddle it.

Fig. 4 shows an example of a specific configuration of the switching unit 20. In fig. 4, a part of the seat 10 is omitted.

The switching unit 20 operates at least one of the intermediate portion 11 and the pair of side portions 12 based on an operation of the controller 54 (see fig. 1), and selects one of the 1 st form (see fig. 1) and the 2 nd form (see fig. 3). In one example, when the seat portion 10 adopts the 1 st form, the switching portion 20 relatively operates the intermediate portion 11 and the pair of side portions 12 such that the intermediate portion 11 is higher than the pair of side portions 12, and selects the 2 nd form. When the seat 10 adopts the 2 nd form, the switching portion 20 operates at least one of the intermediate portion 11 and the pair of side portions 12 such that the difference between the height of the intermediate portion 11 and the height of the pair of side portions 12 is smaller than the difference in the 2 nd form, and selects the 1 st form.

The switching portion 20 includes a link 30 and a seat airbag 40. The seat airbag 40 functions to displace the intermediate portion 11 in the up-down direction by repeating expansion and contraction. The seat airbag 40 is provided below the intermediate portion 11. In one example, the seat airbag 40 is disposed within the linkage 30. The seat airbag 40 is connected to an air pump 41 as a part of the exercise assisting device 1. By supplying air from the air pump 41, the seat airbag 40 is inflated to lift the intermediate portion 11 upward.

The link 30 connects the intermediate portion 11 and the pair of side portions 12 such that the pair of side portions 12 assume an inclined posture as the intermediate portion 11 is displaced upward, for example. The link 30 includes an intermediate link 31, a rear link 33, a support link 34, and a pair of side links 32. The seat airbag 40 is disposed in a space surrounded by the links 31 to 34, for example.

The intermediate link 31 supports the intermediate portion 11. The support link 34 is provided on the base portion 53 (see fig. 1) so as to face the intermediate link 31, and supports various elements constituting the link 30. In one example, the support link 34 is fixed to the base portion 53 so as not to be displaced relative to the base portion 53. The pair of side links 32 are provided on both sides of the intermediate link 31 in the width direction of the seat 10 so as to support the corresponding side portion 12. The rear link 33 is provided on the rear side of the intermediate link 31. The side link 32 and the rear link 33 connect the intermediate link 31 and the support link 34 so that the intermediate link 31 can be displaced in the vertical direction with respect to the support link 34.

The side link 32 includes a 1 st side link 32A and a 2 nd side link 32B. The 1 st side link 32A and the 2 nd side link 32B are coupled to each other so as to be rotatable about an axis along the front-rear direction of the seat 10. An axis along the front-rear direction of the seat 10 exists at a connecting portion of the links. One end of the 1 st side link 32A is rotatably coupled to the intermediate link 31. The other end of the 1 st side link 32A is rotatably coupled to one end of the 2 nd side link 32B. The other end of the 2 nd side link 32B is rotatably coupled to the support link 34. The 1 st side link 32A is longer than the 2 nd side link 32B.

The rear link 33 includes a 1 st rear link 33A and a 2 nd rear link 33B. The 1 st rear link 33A and the 2 nd rear link 33B are coupled to each other so as to be rotatable about an axis along the front-rear direction of the seat 10. One end of the 1 st rear link 33A is rotatably coupled to the intermediate link 31. The other end of the 1 st rear link 33A is rotatably coupled to one end of the 2 nd rear link 33B. The other end portion of the 2 nd rear link 33B is rotatably coupled to the support link 34. The length of the 1 st rear link 33A is substantially the same as the length of the 1 st side link 32A, and the length of the 2 nd rear link 33B is substantially the same as the length of the 2 nd side link 32B.

Fig. 5 shows an external appearance of the exercise assisting device 1 according to the 1 st embodiment, in which a part of the seat 10 is omitted. In the state where the seat 10 takes the 1 st form, the seat airbag 40 is most contracted, and the link 30 is folded. Specifically, by contracting the seat airbag 40, the 1 st side link 32A and the 2 nd side link 32B are folded so as to approach each other, and the 1 st rear link 33A and the 2 nd rear link 33B are folded so as to approach each other. Thus, the intermediate link 31 approaches the support link 34 with the seat airbag 40 interposed therebetween, and the intermediate link 31 and each 1 st side link 32A form a substantially flat surface. The folded rear link 33 is accommodated in the gap 51C of the support member 51B.

In this way, the switching portion 20 causes the seat airbag 40 to contract such that the difference between the height of the intermediate portion 11 and the height of the pair of side portions 12 is smaller than that in the 2 nd form. Then, the switching portion 20 operates the intermediate portion 11 and the pair of side portions 12 in accordance with the deformation of the link 30, and selects the 1 st mode (see fig. 1).

Fig. 6 shows an external appearance of the exercise assisting device 1 according to the 2 nd embodiment, in which a part of the seat 10 is omitted. In the state where the seat 10 takes the 2 nd form, the seat airbag 40 is configured to be inflated to the maximum extent, and the link 30 is deformed so as to extend upward. Specifically, when the seat airbag 40 is inflated to raise the intermediate link 31, the

side links

32A and 32B and the

rear links

33A and 33B deform to extend substantially linearly following the displacement of the intermediate link 31. Thus, the intermediate link 31 and the side links 32 form a shape that simulates a horse back or a saddle.

In this way, the switching portion 20 inflates the seat airbag 40 and deforms the link 30 so that the height of the seat surface 10A of the intermediate portion 11 in the 2 nd form is higher than the height of the seat surface 10A of the intermediate portion 11 in the 1 st form and the pair of side portions 12 assume an inclined posture with respect to the intermediate portion 11. The switching unit 20 operates the intermediate portion 11 and the pair of side portions 12 in accordance with the deformation of the link 30, and selects the 2 nd mode (see fig. 3).

An example of the structure of the driving unit 70 will be described with reference to fig. 7. The specific configuration and operation of the drive unit 70 are substantially the same as those of the drive device disclosed in patent document 1 (japanese patent application laid-open No. 2006-61672), and therefore, a part or all of the same items as those of patent document 1 will be omitted. Fig. 7 shows the seat 10 in a simplified manner.

For example, when the form of the seat 10 is at least the 2 nd form, the driving unit 70 swings the seat 10. In one example, the driving unit 70 swings the seat unit 10 when the form of the seat unit 10 is the 1 st form and when the form of the seat unit 10 is the 2 nd form. The driving unit 70 includes a swing base 71, a 1 st motor 73, an eccentric rod 76, a pair of support plates 72, a pair of crank arms 74, and a pair of connecting links 75. The seat 10 is fixed to the swing base 71 so as to swing together with the swing base 71. The pair of support plates 72 function to support various elements constituting the driving section 70.

The pair of crank arms 74 function to displace the swing base 71 in the front-rear direction of the seat 10 via the connecting link 75. The crank arm 74 is connected to an output shaft (not shown) of the 1 st motor 73 via a plurality of rotating shafts and gears (not shown). One end of the crank arm 74 is connected to a rotating shaft that eccentrically rotates in accordance with the rotation of the output shaft of the 1 st motor 73, and the other end is connected to a connecting link 75. One end of the connecting link 75 is connected to the swing base 71, and the other end is connected to the support plate 72.

The eccentric rod 76 functions to displace the swing table 71 in the width direction of the seat 10. The eccentric rod 76 is connected to an output shaft of the 1 st motor 73 via a plurality of rotating shafts and gears (not shown). One end of the eccentric rod 76 is coupled to a rotating shaft that eccentrically rotates in accordance with the rotation of the output shaft of the 1 st motor 73, and the other end is coupled to a support plate 72.

The driving unit 70 is configured such that, for example, the ratio of the rotational speed of the crank arm 74 to the rotational speed of the eccentric rod 76 is 2: 1. therefore, the seat 10 swings so as to form a substantially V-shape in a plan view. The driving unit 70 may be configured such that the ratio of the rotational speed of the crank arm 74 to the rotational speed of the eccentric rod 76 is 2: 1, and the phase of the crank arm 74 is shifted by 90 ° with respect to the phase of the eccentric rod 76. In this example, the seat 10 swings so as to form a substantially figure-eight shape in a plan view. The driving unit 70 may be configured such that the ratio of the rotational speed of the crank arm 74 to the rotational speed of the eccentric rod 76 is 1: 2.

by rotating the output shaft of the 1 st motor 73, the crank arm 74 is eccentrically rotated by the plurality of rotating shafts and gears, and one end portion of the eccentric rod 76 is eccentrically rotated by the plurality of rotating shafts and gears. The crank arm 74 transmits its rotational motion to the connecting link 75, thereby displacing the connecting link 75 in the front-rear direction of the seat 10. Therefore, the swing base 71 is displaced in the front-rear direction of the seat 10 by the connecting link 75, and the seat 10 is displaced in the front-rear direction.

Further, one end portion of the eccentric rod 76 is displaced in the width direction of the seat 10 by eccentric rotation. Thereby, the support plate 72 is inclined, and the connecting link 75 is displaced in the width direction of the seat 10. Therefore, the swing base 71 is displaced in the width direction of the seat portion 10 via the connecting link 75, thereby displacing the seat portion 10 in the width direction. By rotating the output shaft of the 1 st motor 73 in this way, the seat unit 10 is swung in the front-rear direction and the width direction. Accordingly, the user 100 (refer to fig. 9) using the exercise assisting device 1 is provided with the swing motion.

The exercise assisting device 1 further includes a lifting mechanism 80. The lifting mechanism 80 is provided, for example, on the front side of the seat 10. The elevating mechanism 80 functions to change the inclination of the seat 10 in the front-rear direction. The lifting mechanism 80 includes a 2 nd motor 81 and a telescopic portion 82. The expansion and contraction portion 82 includes, for example, a ball screw (not shown). One end of the expansion portion 82 is connected to the swing table 71, and the other end is connected to a support plate 72. An output shaft (not shown) of the 2 nd motor 81 is coupled to a nut of the ball screw via a worm gear (not shown) or the like.

By rotating the output shaft of the 2 nd motor 81, the nut of the ball screw is rotated via a worm gear or the like, and the threaded shaft of the ball screw is displaced in the vertical direction. Therefore, the telescopic portion 82 extends and contracts, and the front side of the swing base 71 rotates around the connecting shaft 77 connecting the swing base 71 and the connecting link 75. Therefore, the inclination of the swing table 71 in the front-rear direction of the seat 10 is changed, thereby changing the inclination of the seat 10 in the front-rear direction. The lifting mechanism 80 is driven based on the operation of the controller 54 (see fig. 1).

An example of the use state of the exercise assisting device 1 is explained with reference to fig. 8 and 9.

The user 100 using the exercise assisting device 1 selects any one of the 1 st form and the 2 nd form by operating the controller 54.

As shown in fig. 8, the exercise assisting device 1 according to the 1 st aspect is mainly used as a chair or a stretching tool by the user 100. Specifically, the user 100 seats on the seat 10 to use the exercise assisting device 1 as a chair, or operates the controller 54 to drive the rear airbag 61 to use the exercise assisting device 1 as a stretching tool.

As shown in fig. 9, the exercise assisting device 1 in the 2 nd aspect is mainly used as a device for a swing exercise by the user 100. Specifically, the user 100 operates the controller 54 while straddling the seat 10, thereby driving the driving unit 70 to swing the seat 10, and using the exercise assisting apparatus 1 as an apparatus for swing exercise. At this time, when the user 100 operates the controller 54 to drive the holding airbag 62, the position of the leg of the user 100 with respect to the seat portion 10 is held by the holding airbag 62.

The user 100 can also use the exercise assisting device 1 according to the 1 st aspect as a device for swing exercise. Specifically, the user 100 operates the controller 54 while sitting on the seat portion 10, thereby driving the driving portion 70 to swing the seat portion 10, and using the exercise assisting device 1 as a device for swing exercise. The operation of the seat 10 when the seat 10 in the 1 st form swings is substantially the same as the operation of the seat 10 in the 2 nd form, for example. At this time, when the user 100 operates the controller 54 to drive the holding airbag 62, the position of the pelvis of the user 100 with respect to the seat 10 is held by the holding airbag 62, and the user 100 is given a stretching motion of the pelvis or the like. The operation of the seat 10 when the seat 10 in the 1 st form swings may be different from the operation of the seat 10 in the 2 nd form.

In this way, the form that the exercise assisting device 1 can take includes a form that can manage the exercise assisting device 1 in the same way as furniture, and therefore, the exercise assisting device 1 does not become an obstacle even when the user 100 does not use the exercise assisting device 1 as a device for swing motion. Therefore, the exercise assisting device 1 has high convenience.

With the exercise assisting device 1 of the embodiment, the following effects are further obtained.

With the exercise assisting device 1, the pair of side portions 12 in the 2 nd form assume a posture inclined downward toward the outer sides in the width direction of the seat portion 10, and therefore, in a state where the user 100 is straddled on the seat portion 10, the pair of side portions 12 are easily sandwiched by the thighs. Therefore, in the case of performing the swing motion using the exercise assisting device 1, the posture of the user 100 is easily stabilized. Further, with the exercise assisting device 1, since the width of the intermediate portion 11 becomes narrower from the rear side to the front side of the seat portion 10, it is easy for the user 100 who straddles the seat portion 10 in the 2 nd form to sandwich the intermediate portion 11 with his/her thigh.

With the exercise assisting device 1, the front portion 11A bulges upward from the rear portion 11B. On the other hand, when the user 100 straddles the seat 10 in the 2 nd embodiment, for example, the buttocks are supported by the rear portion 11B, and the front portion 11A is positioned in front of the body. Therefore, even when the swing motion is performed using the exercise assisting device 1, the forward movement of the body with respect to the seat portion 10 can be prevented by the bulging of the front portion 11A. Therefore, in the case of performing the swing motion using the exercise assisting device 1, the posture of the user 100 is more easily stabilized.

When the feet of the user 100 straddling the seat 10 of the 2 nd embodiment are raised from the floor, the user 100 does not support the feet by the swinging motion of the seat 10, and thus the amount of exercise of the user 100 increases. On the other hand, in the exercise assisting device 1, since the height of the seat surface 10A of the intermediate portion 11 in the 2 nd form is set to be higher than that in the 1 st form, the feet of the user 100 who straddles the seat 10 in the 2 nd form are likely to float from the floor. Therefore, the effect of the user 100 accompanying the swing motion of the seat 10 can be improved.

When the user 100 straddles the seat 10 in the 2 nd embodiment, the back support portion 13 can be used to determine the position of the waist. Since the back support portion 13 supports the waist or the hip of the user 100, the position of the waist of the user 100 on the seat portion 10 is stable, and the posture of the user 100 is easily stabilized when the seat portion 10 performs the swing motion.

The pair of armrests 52 have a shape in which, for example, in the front-rear direction of the seat 10, the upper portion protrudes forward and the lower portion is drawn rearward. Therefore, when the user 100 straddles the seat 10 in the 2 nd mode, the legs of the user 100 are less likely to contact the armrests 52. Therefore, the user can smoothly straddle the seat 10 according to embodiment 2, and the legs of the user 100 are less likely to contact the armrests 52 even when the seat 10 swings.

With regard to the link 30 of the exercise assisting device 1, the length of the 1 st side link 32A is longer than the length of the 2 nd side link 32B. In this case, when the seat airbag 40 is inflated to the maximum, the inclination of the 1 st side link 32A with respect to the intermediate link 31 increases. Therefore, the inclination of the pair of side portions 12 with respect to the intermediate portion 11 is increased, and it is easy to strongly sandwich the pair of side portions 12 with the thighs in a state where the user 100 straddles the seat portion 10. Therefore, in the case of performing the swing motion using the exercise assisting device 1, the posture of the user 100 is further easily stabilized.

The orientation of the user 100 seated on the seat 10 when the exercise assisting device 1 adopts the 1 st aspect is the same as the orientation of the user 100 straddling the seat 10 when the exercise assisting device 1 adopts the 2 nd aspect. Therefore, with the exercise assisting device 1, the 1 st and 2 nd configurations can be switched while the user 100 is maintaining the posture of sitting on the seat portion 10 or straddling over the seat portion 10. Therefore, the convenience of the exercise assisting device 1 can be improved.

The 2 nd position sensor has a slit, 1 light emitting portion or a plurality of light emitting portions, and a plurality of light receiving portions, and thus can detect which position of the seat 10 is located in 5 stages.

The controller 54 has a plurality of keys and a display unit formed of, for example, a liquid crystal display device, and receives various operations such as turning on and off of power supply from a user and switching of modes. The controller 54 may be formed of, for example, an electrostatic or resistive touch panel.

The storage unit 503 is a nonvolatile Memory such as an EEPROM (Electrically Erasable and Programmable Read Only Memory), and stores various programs and data (for example, a flag indicating which mode the apparatus is currently in, and various parameters) executed by the control unit 500.

The air pump 41 is a pump that supplies air to the seat airbag 40, the back airbag 61, and the holding airbag 62. In the present embodiment, only 1 air pump 41 is mounted, but a plurality of air pumps 41 may be mounted.

The 1 st electromagnetic valve 504 is connected to the seat airbag 40, and is a valve for switching to supply or not supply air from the air pump 41 to the seat airbag 40.

The 2 nd electromagnetic valve 505 is connected to the rear airbag 61 and is a valve for switching to supply or not supply the air from the air pump 41 to the rear airbag 61.

The 3 rd electromagnetic valve 506 is connected to one of the holding bladders 62, and is a valve for switching to supply or not supply the air from the air pump 41 to one of the holding bladders 62.

The 4 th electromagnetic valve 507 is connected to the other holding bladder 62, and is a valve for switching to supply or not supply air from the air pump 41 to the other holding bladder 62.

The holding valve 600 is a valve for holding air supplied to the airbag. In the apparatus of the present embodiment, the air pump 41 is connected to the holding valve 600 and the 2 nd electromagnetic valve 505, and the holding valve 600 is connected to the 1 st electromagnetic valve 504, the 3 rd electromagnetic valve 506, and the 4 th electromagnetic valve 507.

Further, the 3 rd solenoid valve 506 and the 4 th solenoid valve 507 may be configured by 1 solenoid valve. In the case of such a structure, the two holding airbags 62 are simultaneously supplied with air and exhausted with air.

Further, a plurality of holding valves 600 may be provided, and each holding valve 600 may be connected to a corresponding solenoid valve.

Fig. 16A and 16B are flowcharts showing the operation of the exercise assisting device according to embodiment 6.

In embodiment 6, the exercise assisting device has two modes, i.e., a saddle riding mode (1 st mode) and a seat mode (2 nd mode), and the user can switch the two modes by operating the controller 54. The riding mode (1 st mode) is a mode performed when the exercise assisting device 1 takes the above-described 2 nd form, and the seat mode (2 nd mode) is a mode performed when the exercise assisting device 1 takes the above-described 1 st form.

In addition, hereinafter, the state of the user in the seat mode (2 nd mode) may be expressed as "no-riding state". The "non-straddled state" is, as described above, a posture that the user takes when the exercise assisting device 1 is used as in a general chair, and may be expressed as "the user can sit on".

The seat mode is a mode in which the seat 10 is swung in a substantially flat state, and the saddle riding mode is a mode in which the seat 10 is swung in a partially raised state. Here, the "state in which a part of the seat portion 10 is raised" means, for example, a state in which the front portion 11A is raised above the rear portion 11B in the exercise assisting device 1.

In the horse riding mode, the user can obtain a sensation as if riding a horse.

In addition, the user can use the exercise assisting device as a normal chair in a state where the exercise assisting device is in neither the seat mode nor the horse riding mode.

When the power-on operation is performed from the controller 54 in the standby state and then an instruction operation is given, the control unit 500 advances the process to step S10.

In addition, the standby state is a state in which the control portion 500 waits for an instruction operation from the controller 54, for example, is in neither the seat mode nor the riding mode, and the control portion 500 waits for an instruction operation from the controller 54.

In step S10, when the control section 500 determines that the operation from the controller 54 is an instruction to start the seat mode (Yes in step S10), data (e.g., a flag) indicating that it is the seat mode at the present time is stored in the storage section 503, and the process proceeds to step S11. On the other hand, in step S10, when the control section 500 determines that it is an instruction to start the saddle mode (No in step S10), data (e.g., flag) indicating that it is the saddle mode at the present time is stored in the storage section 503, and the process proceeds to step S14.

In step S11, the control portion 500 drives the air pump 41, and controls the 3 rd electromagnetic valve 506 and the 4 th electromagnetic valve 507, thereby starting the supply of air to the holding airbag 62. Further, the timing of a predetermined time (for example, 10 seconds) is started.

In the next step S12, when the control unit 500 determines that the predetermined time (e.g., 10 seconds) has elapsed (Yes in step S12), it determines that the air supply to the holding airbag 62 is completed, controls the holding valve 600 to hold the air pressure, and advances the process to step S13.

In the present embodiment, even in the seat mode, the seat 10 is in a substantially flat state, and air can be supplied to the seat airbag 40 at a predetermined percentage (for example, 50%) of the air that can enter the seat airbag 40. In this case, (a part of) the seat 10 is not as high as the riding mode, but is slightly raised.

In step S13, the controller 500 controls the 1 st motor 73 to start swinging the seat 10, and advances the process to step S16.

The rotation speed of the 1 st motor 73 (in other words, the swing speed of the seat 10) in step S13 is a (revolutions per minute).

In step S14, the control portion 500 starts supplying air to the seat airbag 40 by driving the air pump 41 and controlling the 1 st electromagnetic valve 504. Further, the control unit 500 starts counting a predetermined time (for example, 40 seconds).

In the present embodiment, air is sufficiently supplied to the seat airbag 40, but air may be supplied at a predetermined percentage (for example, 50%) of the air that can enter the seat airbag 40. In this case, the height of the raised portion of the seat 10 is lower than in the case where air is sufficiently supplied.

In the next step S15, when the control unit 500 determines that the predetermined time (e.g., 40 seconds) has elapsed, it determines that the air supply to the seat airbag 40 is completed (Yes in step S15), controls the hold valve 600 to hold the air pressure, and advances the process to step S13.

In step S16, when control unit 500 determines that an instruction operation for mode change has been performed from controller 54 (Yes in step S16), the process proceeds to step S23, and if not (No in step S16), the process proceeds to step S17.

In step S17, when control unit 500 determines that an instruction operation to end has been performed from controller 54 (Yes in step S17), the process proceeds to step S18, and if not (No in step S17), the process returns to step S16.

In step S18, the control unit 500 reads data (for example, a flag) indicating which mode the current mode is stored in the storage unit 503, and determines whether the current exercise assisting device is in the seat mode. When the controller 500 determines that the mode is the seat mode (Yes at step S18), the process proceeds to step S19, and if not (No at step S18), the process proceeds to step S21.

In step S19, the control unit 500 drives the 1 st motor 73 to make the seat 10 horizontal, until the output from the 1 st position sensor 501 becomes the output of the seat 10 in the horizontal position, and stops the swing of the seat 10.

When the seat 10 is tilted in the front-rear direction, the control unit 500 drives the 2 nd motor 81 to drive the 2 nd motor 81 so that the seat 10 is in a horizontal state until the output from the 2 nd position sensor becomes the output in the state where the seat 10 is in the horizontal position.

In step S20, the control unit 500 controls the 3 rd solenoid valve 506 and the 4 th solenoid valve 507 to discharge the air in the left and right retention airbags 62, and stands by for the operation from the controller 54.

In step S21, the control unit 500 drives the 1 st motor 73 to make the seat portion horizontal, until the output from the 1 st position sensor 501 becomes the output of the seat portion 10 in the horizontal position, and stops the swing of the seat portion 10.

When the seat 10 is tilted in the front-rear direction, the control unit 500 drives the 2 nd motor 81 to drive the 2 nd motor 81 so that the seat is in a horizontal state until the output from the 2 nd position sensor becomes the output of the seat 10 in the horizontal state.

In step S22, the control unit 500 controls the 1 st electromagnetic valve 504 to discharge the air in the seat airbag 40, and waits for an operation from the controller 54.

In step S23, the control unit 500 reads data (e.g., a flag) indicating the current state stored in the storage unit 503, determines whether the current exercise assisting device 1 is in the seat mode, and if it is determined that the device is in the seat mode (Yes in step S23), the process proceeds to step S24, and if not (No in step S23), the process proceeds to step S31.

In step S24, the controller 500 decreases the rotation speed of the 1 st motor 73 (decreases the swing speed of the seat unit), and the process proceeds to step S25.

The rotation speed of the 1 st motor 73 at this time (in other words, the swing speed of the seat) is B (revolutions per minute). In addition, the rotation speed B of the 1 st motor 73 in step S24 is slower than the rotation speed a of the 1 st motor 73 in step S13.

In step S25, the control unit 500 starts to discharge the air in the holding bag 62 and starts to count a predetermined time (for example, 4 seconds) by controlling the 3 rd solenoid valve 506 and the 4 th solenoid valve 507.

Further, the controller 500 may perform the processing of step S24 and the processing of step S25 at the same time.

In step S26, when the 4 second timer started in step S25 ends, the control unit 500 drives the air pump 41 and controls the 1 st electromagnetic valve 504 to start supplying air to the seat airbag 40. In addition, the timing of a predetermined time (for example, 10 seconds) is started.

In step S27, when the control unit 500 determines that the timer counting for a predetermined time (for example, 10 seconds) has ended after the timer counting is started in step S26 (Yes in step S27), the process proceeds to step S28. Further, the control unit 500 starts counting a predetermined time (for example, 30 seconds).

In step S28, the control unit 500 increases the rotation speed of the 1 st motor 73 (increases the swing speed of the seat unit).

The rotation speed of the 1 st motor 73 at this time (in other words, the swing speed of the seat) is C (revolutions per minute). In addition, the rotation speed C of the 1 st motor 73 in step S28 is faster than the rotation speed B of the 1 st motor 73 in step S24.

In step S29, when the controller 500 determines that 30 seconds have elapsed since the predetermined time (for example, 30 seconds) counted in step S27 (Yes in step S29), the process proceeds to step S30.

In step S30, the control unit 500 controls the hold valve 600 to hold the air pressure in the seat airbag 40, and the process returns to step S16.

In step S31, the control unit 500 decreases the rotation speed of the 1 st motor 73 (decreases the swing speed of the seat unit).

The rotation speed of the 1 st motor 73 at this time (in other words, the swing speed of the seat) is B (revolutions per minute). In addition, the rotation speed B of the 1 st motor 73 in step S31 is slower than the rotation speed a of the 1 st motor 73 in step S13.

In step S32, the control unit 500 starts the exhaust of the seat airbag 40 by controlling the 1 st electromagnetic valve 504. Further, the control unit 500 starts counting a predetermined time (for example, 10 seconds).

Further, the controller 500 may perform the processing of step S31 and the processing of step S32 at the same time.

In step S33, when the timing of the predetermined time (e.g., 10 seconds) started in step S32 is completed, the control portion 500 drives the air pump 41, and controls the 3 rd electromagnetic valve 506 and the 4 th electromagnetic valve 507, thereby starting the supply of air to the holding airbag 62 and starting the timing of the predetermined time (e.g., 10 seconds).

In step S34, when the control unit 500 determines that the timer count has ended for a predetermined time (for example, 10 seconds) since the timer count started in step S33 (Yes in step S34), the process proceeds to step S35.

In step S35, the control unit 500 controls the holding valve 600 to hold the air pressure of the holding bladder 62.

In step S36, the controller 500 increases the rotation speed of the 1 st motor 73 (increases the swing speed of the seat unit), and returns the process to step S16.

The rotation speed of the 1 st motor 73 at this time (in other words, the swing speed of the seat) is C (revolutions per minute). In addition, the rotation speed C of the 1 st motor 73 in step S36 is faster than the rotation speed B of the 1 st motor 73 in step S31.

Further, the control unit 500 may execute the process of step S35 after the process of step S36 is performed.

As described above, in the present embodiment, when the control unit 500 determines that the instruction operation for mode change has been performed from the controller 54 (for example, a change from the seat mode to the saddle mode or a change from the saddle mode to the seat mode), the rotation speed of the 1 st electric motor 73 (the swing speed of the seat unit) is reduced and the mode is changed.

Therefore, the user can feel that the stretching by the swinging of the seat unit 10 is continuously performed, as compared with the case where the mode is changed after the swinging operation is temporarily stopped. In addition, since the swing speed of the seat section is reduced, the mode can be safely changed.

In the present embodiment, in the seat mode, the seat unit 10 swings with the left and right holding airbags 62 inflated in steps S10 to S13. In this way, the seat unit 10 swings while the vicinity of the pelvis and the waist is held from the left and right by the holding airbags 62, and therefore, the vicinity of the pelvis and the waist can be effectively stretched.

Further, since the vicinity of the pelvis and the waist is fixed by the left and right holding airbags 62, even if the seat 10 swings, the user can continue to sit on the seat 10 in a stable state, and a significant effect is obtained in terms of safety.

In the present embodiment, after the seat 10 is set to the horizontal state in step S19 and step S21, the air in the seat airbag 40 or the holding airbag 62 is discharged, and the seat mode or the riding mode is ended. Therefore, the user can use the exercise assisting device as a normal chair even in a state where the exercise assisting device is not operated.

Embodiment 6 may be a modification as described below.

In the present embodiment, the rotation speed a of the motor (swing speed of the seat) in the seat mode or the saddle mode in step S13 may be the same as the rotation speed C of the motor (swing speed) in the seat mode or the saddle mode after completion of the increase in the rotation speed in steps S28 and S36, or the rotation speed a may be different from the rotation speed C.

In the present embodiment, when the control unit 500 determines that 10 seconds have elapsed in step S27 after the timer of the predetermined time is started in step S26, the swing speed is increased in step S28, but the timing of starting the timer of the predetermined time is not limited to step S26. The timing may be started at the timing when the swing speed is reduced, the timing when the air in the holding bag 62 is discharged, and the timing when the air is supplied to the seat bag 40. The predetermined time in step S27 is 10 seconds, but is not limited to 10 seconds.

In the present embodiment, when the control unit 500 determines that 10 seconds have elapsed in step S34 after the timer of the predetermined time is started in step S33, the swing speed is increased in step S36, but the timing of starting the timer of the predetermined time is not limited to step S33. The timing may be started at the timing when the swing speed is reduced, the timing when the air is supplied into the holding bag 62, and the timing when the air in the seat bag 40 is discharged. The predetermined time in step S34 is 10 seconds, but is not limited to 10 seconds.

In the present embodiment, the user switches the riding mode and the seat mode by operating the controller 54, but the riding mode and the seat mode may be automatically switched in a series of steps. In this case, for example, in step S10 and step S16 of fig. 16, the control unit 500 can determine whether the mode to be executed next in a series of processes is the horse riding mode or the seat mode based on the data (e.g., the flag) stored in the storage unit 503.

In the present embodiment, as shown in fig. 1, the left and right holding airbags 62 are disposed above the armrests 52, but when it is desired to hold the pelvis and the vicinity of the buttocks from the left and right, the holding airbags 62 may be disposed closer to the center or lower side of the armrests 52 than in fig. 1.

In the present embodiment, the left and right holding airbags 62 are disposed on the armrests 52, but a configuration in which they are disposed on the seat portion 10 is also conceivable. With the above-described structure, the periphery of the pelvis and the waist of the user can be held in the seat mode. In the case of the above-described configuration, the exercise assisting device 1 according to the present embodiment can be used as a normal chair having the backrest 51 without the armrest 52 in a state of being in neither the seat mode nor the horse riding mode.

The swing speed of the seat 10 may be suddenly reduced or increased, but may be gradually reduced or increased, or may be gradually reduced or increased in stages. The seat 10 is preferably changed slowly or stepwise. This is because the user can be prevented from being surprised by a sudden change in the swing speed of the seat portion 10 as much as possible.

(embodiment 7)

Next, embodiment 7 will be explained.

Embodiment 6 differs from embodiment 7 in the following point. In embodiment 6, the control unit 500 starts counting of a predetermined time (10 seconds) at step S26, increases the swing speed at step S28 when 10 seconds have elapsed at step S27, and maintains the air pressure of the seat airbag 40 at step S30 when 30 seconds have elapsed as determined at step S29. On the other hand, in embodiment 7, the timing of a predetermined time (for example, 40 seconds) by the control unit 500 is started at the same time as the air supply to the seat airbag 40 is started, and when the predetermined time elapses, the swing speed is increased.

That is, steps S24 to S30 in fig. 16A and 16B as the flowchart of embodiment 6 and steps S124 to S129 in fig. 17A and 17B as the flowchart of embodiment 7 are different from each other, and other steps are the same, and therefore, the description of the same parts will be omitted.

More specifically, steps S10 to S22 in fig. 16A and 16B are the same as steps S110 to S122 in fig. 17A and 17B, and steps S31 to S36 in fig. 16B are the same as steps S130 to S135 in fig. 17B.

The block diagram of embodiment 7 is also the same as that of embodiment 6.

In step S124 of fig. 17B, the control unit 500 decreases the rotation speed of the 1 st motor 73 (the swing speed of the seat unit) and advances the process to step S125.

The rotation speed of the 1 st motor 73 at this time (in other words, the swing speed of the seat) is B (revolutions per minute). The rotation speed B of the 1 st motor 73 in step S124 is slower than the rotation speed a of the 1 st motor 73 in step S113.

In step S125, the control unit 500 starts to discharge the air in the holding bag 62 and starts to count a predetermined time (for example, 4 seconds) by controlling the 3 rd solenoid valve 506 and the 4 th solenoid valve 507.

In step S126, when the 4 second timer started in step S125 ends, the control unit 500 drives the pump and controls the 1 st electromagnetic valve 504 to start supplying air to the seat airbag 40. In addition, the timing of a predetermined time (for example, 40 seconds) is started.

In step S127, when the control unit 500 determines that the timer counting for a predetermined time (for example, 40 seconds) has ended after the timer counting is started in step S126 (Yes in step S127), the process proceeds to step S128.

In step S128, the control unit 500 controls the hold valve 600 to hold the air pressure of the seat airbag 40.

In step S129, the control unit 500 increases the rotation speed of the 1 st motor 73, and returns the process to step S116.

Embodiment 7 may be a modification as described below.

In the present embodiment, when the control unit 500 determines that 40 seconds have elapsed in step S127 after the start of the counting of the predetermined time (for example, 40 seconds) in step S126, the air is held in step S128, but the timing of the start of the counting of the predetermined time is not limited to step S126. The time measurement may be started at the timing when the swing speed is reduced (step S124), the timing when the air in the holding bag 62 is discharged (step S125), and the timing when the air is supplied to the seat bag 40 (step S126). The predetermined time in step S127 is set to 40 seconds, but is not limited to 40 seconds.

In the present embodiment, the rotation speed a of the motor (swing speed of the seat unit) in the seat mode or the saddle mode in step S113 may be set to the same rotation speed as the rotation speed C of the motor in the seat mode or the saddle mode after completion of the increase in the rotation speed in step S129 and step S135, or the rotation speed a may be different from the rotation speed C.

In the present embodiment, when the control unit 500 determines that 10 seconds have elapsed in step S133 after the start of the counting of the predetermined time in step S132, the air pressure is maintained in step S134, but the timing of the start of the counting of the predetermined time is not limited to step S132. The timing may be started at the timing when the swing speed is reduced, the timing when the air is supplied into the holding bag 62, and the timing when the air in the seat bag 40 is discharged. The predetermined time in step S133 is 10 seconds, but is not limited to 10 seconds.

In the present embodiment, the user switches the riding mode and the seat mode by operating the controller 54, but the riding mode and the seat mode may be automatically switched in a series of steps. In this case, for example, in step S110 and step S116 of fig. 17A, the control unit 500 can determine whether the mode to be executed next in a series of processes is the horse riding mode or the seat mode based on the data (e.g., the flag) stored in the storage unit 503.

(embodiment mode 8)

Next, embodiment 8 will be explained.

Embodiment 8 is different from embodiments 6 and 7 in that the mode is changed while the seat 10 is kept swung in embodiments 6 and 7, but the mode is changed after the seat 10 is temporarily set to a horizontal state in embodiment 8.

Therefore, the block diagrams are the same in embodiment 6, embodiment 7, and embodiment 8. On the other hand, regarding the flowchart, steps S224 to S233 in fig. 18B, which is the flowchart of embodiment 8, are different from the flowcharts in fig. 16B and 17B, and the other steps are the same as those in embodiment 6 and embodiment 7, and therefore, the description of the same parts is omitted.

In step S224 in fig. 18B, the control unit 500 drives the 1 st motor 73 to make the seat 10 horizontal, and stops the swing of the seat 10 until the output from the 1 st position sensor 501 becomes the output of the seat 10 in the horizontal position.

When the seat 10 is tilted in the front-rear direction, the 2 nd motor 81 is driven, and the 2 nd motor 81 is driven to make the seat 10 horizontal until the output from the 2 nd position sensor 502 becomes the output of the seat 10 in the horizontal position.

In step S225, the control unit 500 controls the 3 rd solenoid valve 506 and the 4 th solenoid valve 507 to discharge the air in the left and right retention bladders 62.

In step S226, the control portion 500 drives the air pump 41, and controls the 1 st electromagnetic valve 504, thereby starting the supply of air to the seat airbag 40.

In step S227, the control unit 500 maintains the air pressure of the seat airbag 40.

In step S228, the control unit 500 controls the 1 st motor 73 to start the swing operation of the seat unit 10, and returns the process to step S216.

In step S229 in fig. 18B, the control unit 500 drives the 1 st motor 73 to make the seat unit 10 horizontal, and stops the swing of the seat unit 10 until the output from the 1 st position sensor becomes the output of the seat unit 10 in the horizontal position.

When the seat 10 is tilted in the front-rear direction, the 2 nd motor 81 is driven, and the 2 nd motor 81 is driven to make the seat 10 horizontal until the output from the 2 nd position sensor becomes the output of the seat 10 in the horizontal position.

In step S230, the control unit 500 controls the 1 st electromagnetic valve 504 to discharge the air in the seat airbag 40.

In step S231, the control unit 500 starts air supply to the left and right holding airbags 62 by controlling the 3 rd electromagnetic valve 506 and the 4 th electromagnetic valve 507.

In step S232, the control unit 500 maintains the air pressure of the retention bladder 62.

In step S233, the control unit 500 controls the 1 st motor 73 to start the swing operation of the seat unit 10.

As described above, in embodiment 8, in the mode change, the exhaust or supply of the seat airbag 40 or the holding airbag 62 is performed after the seat 10 is temporarily placed in the horizontal state.

Therefore, the user feels the state in which the seat 10 is temporarily horizontal through the body, and can recognize the change pattern.

When the seat mode and the riding mode are executed for a long time, the user can rest for a short period of time while the seat unit 10 is temporarily kept horizontal.

Embodiment 8 may be a modification as described below.

In the present embodiment, the user switches the riding mode and the seat mode by operating the controller 54, but the riding mode and the seat mode may be automatically switched in a series of steps. In this case, for example, in step S210 and step S216 in fig. 18A, the control unit 500 can determine whether the mode to be executed next in a series of processes is the horse riding mode or the seat mode based on the data (e.g., the flag) stored in the storage unit 503.

(embodiment mode 9)

Next, embodiment 9 will be explained.

The block diagram of embodiment 9 is the same as that shown in fig. 15, and therefore, the description thereof is omitted.

The exercise assisting device 1 according to embodiment 9 has the same structure as the exercise assisting device 1 according to any one of embodiments 1 to 8 described above, and therefore, description thereof is omitted.

Fig. 19A, 19B, and 19C are diagrams showing examples of use of the exercise assisting device 1 according to embodiment 9.

In the present embodiment, the control unit 500 controls the 1 st motor 73 to maintain the state in which the exercise assisting device 1 is tilted to the left or right. In this state, when the exercise assisting device 1 is tilted to the left, the user can twist the upper body to the right, and when the exercise assisting device 1 is tilted to the right, the user can twist the upper body to the left, and the upper body, particularly, the vicinity of the waist can be stretched. With the exercise assisting device 1 of the present embodiment, the user can stretch the lateral abdomen, particularly the oblique abdominal muscle.

First, as shown in fig. 19A, the user sits on the seat 10. At this time, the left and right holding airbags 62 are in an unexpanded state.

Next, when the user performs an operation for executing the operation of embodiment 9, the control unit 500 determines that an instruction operation for executing the operation of embodiment 9 is performed from the controller 54. Then, the control unit 500 controls the air pump 41, the 3 rd electromagnetic valve 506, and the 4 th electromagnetic valve 507 to inflate the left and right holding airbags 62.

Next, the controller 500 controls the 1 st motor 73 to maintain the seat 10 in a state of being inclined at a predetermined angle to the right side as shown in fig. 19B. At this time, a sound "please stretch the back muscle and raise the right arm upward" is emitted from the speaker not shown, and then a sound "please bend the right arm leftward and incline the upper half of the body leftward" is emitted from the speaker. In this way, the user is informed of the sequence of stretching actions from the speaker. When the user follows this notification, the user is in a state in which the body is tilted to the left side as shown in fig. 19C.

The user can perform stretching to stretch the right abdomen in this manner.

Subsequently, stretching for stretching the left abdomen can be performed in the same manner. Specifically, the controller 500 controls the 1 st motor 73 to first maintain the seat 10 in a state of being tilted at a predetermined angle to the left. At this time, a sound "please stretch the back muscle and raise the left arm upward" is emitted from the speaker not shown, and then a sound "please bend the left arm to the right side and tilt the upper body to the right" is emitted from the speaker. In this way, the user is informed of the sequence of stretching actions from the speaker. When the user follows the notification, the user is in a state of inclining his or her body to the right side.

By thus inclining the seat unit 10 alternately to the right and left sides, the user can stretch the flank.

The predetermined angle is, for example, an angle of 10 to 25 degrees in which the seat 10 is inclined to the right or left with respect to the floor surface, and the seat 10 is maintained in the inclined state at the angle. The predetermined angle is not limited to the angle (about 10 degrees to 25 degrees).

When determining that the operation of embodiment 9 is performed from the controller 54, the control unit 500 determines whether the current apparatus is in the seat mode or the riding mode based on the data (e.g., the flag) stored in the storage unit 503. When it is determined that the seat mode is the seat mode, the 1 st motor 73 is controlled so that the seat 10 is tilted to the right or left side by a predetermined angle and maintained in the tilted state.

On the other hand, when determining that the current device is in the riding mode, the control unit 500 prohibits the seat unit 10 from being tilted at a predetermined angle to the right or left, or controls the 1 st electromagnetic valve 504 to discharge the air in the seat unit air bag 40, and after the seat unit 10 is in a substantially flat state with respect to the floor, the left and right holding air bags 62 are inflated, and the seat unit 10 is tilted at a predetermined angle to the right or left.

The period in which the seat 10 is kept inclined at the predetermined angle may be set to a predetermined time (for example, 10 seconds) until the user operates the controller 54.

The timing of outputting the stretching instruction sound from the speaker may be when the seat 10 is operated to tilt, or may be when the seat 10 stops tilting.

In addition, in a state where the seat portion 10 is tilted to the right or left, the raising operation of a part of the seat portion 10 may be prohibited. This is because, when a part of the seat 10 ascends in a state where the seat 10 is inclined, the user may fall down according to the difference in the inclination degree of the seat 10.

The embodiment of embodiment 9 can be described as follows.

The exercise assisting device 1 according to embodiment 9 includes a backrest 51 and a seat 10 that can swing, and can maintain a state in which the seat 10 is tilted at a predetermined angle to the right or left.

Further, the seat 10 has a 1 st mode and a 2 nd mode, and in the 1 st mode, the seat 10 swings in a state where a part of the seat 10 is raised, and in the 2 nd mode, the seat 10 swings in a state where a part of the seat 10 is not raised or in a state where a raised height of a part of the seat 10 is lower than that in the 1 st mode, and in the 2 nd mode, a state where the seat 10 is inclined at a predetermined angle to the right or left can be maintained.

In the mode 2, the seat 10 may be prohibited from swinging while the seat 10 is kept inclined at a predetermined angle to the right or left.

In the 1 st mode, the operation for maintaining the state in which the seat 10 is tilted at a predetermined angle to the right or left may be prohibited.

In the 1 st mode, the seat 10 may be prohibited from being tilted to the right or left.

(embodiment mode 10)

Next, embodiment 10 will be explained.

The block diagram of embodiment 10 is the same as that shown in fig. 15, and therefore, the description thereof is omitted.

The exercise assisting device 1 according to embodiment 10 has the same structure as the exercise assisting device 1 according to any one of embodiments 1 to 9 described immediately above, and therefore description thereof is omitted.

In the present embodiment, the user stretches the seat unit 10 in a state where the seat unit 10 is tilted forward or backward at a predetermined angle by controlling the 2 nd motor 81 by the control unit 500. For example, the user can perform abdominal muscle exercise or exercise for stretching the back muscle by stretching both hands while tilting the seat unit 10 forward or backward.

Specifically, when determining that a predetermined operation is performed from the controller 54, the control unit 500 controls the 2 nd motor 81 so that the seat unit 10 is tilted forward or backward at a predetermined angle and maintains the tilted state.

At this time, the user is notified from a speaker not shown that stretching is to be performed. For example, a sound indicating stretching such as "stretch the back muscle while stretching the leg bar" is output from the speaker.

The predetermined angle is, for example, an angle of 10 to 25 degrees in which the seat 10 is inclined rearward or forward with respect to the ground, and the seat 10 is maintained in the inclined state at the angle. The predetermined angle is not limited to the angle (about 10 degrees to 25 degrees).

When determining that a predetermined operation is performed from the controller 54, the control unit 500 determines whether the current device is in the seat mode or the horse riding mode based on data (e.g., a flag) stored in the storage unit 503. When it is determined that the seat mode is the seat mode, the 2 nd motor 81 may be controlled so that the seat unit 10 is tilted forward or backward at a predetermined angle and maintained in the tilted state.

On the other hand, when determining that the current device is in the riding mode, the control unit 500 may prohibit the seat unit 10 from being tilted forward or backward by a predetermined angle, or may control the 1 st electromagnetic valve 504 to discharge air in the seat unit airbag 40, and may tilt the seat unit 10 forward or backward by a predetermined angle after the seat unit 10 is in a substantially flat state.

The embodiment of embodiment 10 can be described as follows.

The exercise assisting device 1 according to embodiment 10 includes a backrest 51 and a seat 10 that can swing, and can maintain a state in which the seat 10 is tilted forward or backward at a predetermined angle.

Further, there are a 1 st mode and a 2 nd mode, in the 1 st mode, the seat 10 swings in a state where a part of the seat 10 is raised, in the 2 nd mode, the seat 10 swings in a state where a part of the seat 10 is not raised or in a state where a raised height of a part of the seat 10 is lower than that in the 1 st mode, and in the 2 nd mode, a state where the seat 10 is inclined at a predetermined angle in the forward or rearward direction can be maintained.

In the 2 nd mode, the seat 10 is prohibited from swinging while maintaining the state in which the seat 10 is tilted forward or backward at a predetermined angle.

In the 1 st mode, the seat 10 may be prohibited from being tilted forward or backward at a predetermined angle.

In the 1 st mode, the seat 10 is prohibited from being tilted forward or backward.

(embodiment mode 11)

Embodiment 11 is to bring the exercise assisting apparatus 1 into a shape preferred by the user when the user finishes using the exercise assisting apparatus 1 in addition to the above-described embodiments.

More specifically, when the exercise assisting device 1 swings in the riding mode or the seat mode and the user performs an operation for ending these modes, the seat portion 10 is stopped in a state of being inclined at an angle set in advance by the user.

The following description will be made in detail. When the exercise assisting device 1 is in the standby state, the riding mode, or the seat mode, the control unit 500 determines that the setting operation of the angle of the seat unit 10 at the time of ending the riding mode or the seat mode is performed from the controller 54, and stores information of the angle of the seat unit 10 in the storage unit 503 based on the operation from the controller 54.

At this time, the storage unit 503 stores information on any of 5 stages, i.e., a state where the seat unit 10 is tilted forward by 10 degrees, a state where the seat unit is tilted forward by 5 degrees, a state where the seat unit is horizontal to the ground (the tilt angle is 0), a state where the seat unit is tilted backward by 5 degrees, and a state where the seat unit is tilted backward by 10 degrees.

The angle described above is an example, and the angle and the number of stages may be changed as appropriate.

When the user uses the exercise assisting device 1 in the riding mode or the seat mode and the control unit 500 determines that the controller 54 has performed an operation to finish the use of the exercise assisting device 1, the information on the angle at which the seat unit 10 is tilted, which is stored in the storage unit 503, is read, and the 2 nd motor 81 is controlled so that the seat unit 10 becomes the read angle.

By forming such a structure as described above, when the exercise assisting device 1 is used as a chair in a standby state, the user can sit the seat 10 obliquely at a desired angle on the seat 10.

In the standby state, when the controller 500 determines that the operation of tilting the seat unit 10 is performed from the controller 54, the controller may control the 2 nd motor 81 so that the user tilts the seat unit 10 at a desired angle.

By forming such a structure as described above, the user can tilt the seat 10 at a desired angle in the standby state, thereby using the exercise assisting device 1 as a chair capable of automatic adjustment.

The control unit 500 may store the angle of the seat unit 10 in the storage unit 503 in the standby state immediately before the start of the riding mode or the seat mode automatically or based on the user's operation, and perform control to incline the seat unit 10 to the angle stored in the storage unit 503 when the riding mode or the seat mode is finished and the seat unit shifts to the standby state.

In embodiment 11, the seat 10 can be set to an angle in the front-rear direction in the standby state, but the shape of the seat 10, the height of the seat surface, the inclination direction and angle of the exercise assisting device 1 with respect to the floor surface, and the like may be set.

(modification example)

The description of the embodiments is an example of the form that the exercise assisting device of the present disclosure can take, and is not intended to limit the form. In addition to the above embodiments, the exercise assisting device of the present disclosure may take a form in which, for example, modifications of the embodiments shown below and at least two modifications that are not mutually inconsistent are combined.

As shown in fig. 14, the armrest 52 according to the modification of embodiment 1 is vertically displaceable in conjunction with the intermediate portion 11. Specifically, the armrest 52 is displaced in the vertical direction relative to the backrest 51 in conjunction with the vertical displacement of the intermediate portion 11 caused by the expansion or contraction of the seat airbag 40. The armrest 52 is displaced in the up-down direction by a motor or the like, for example. Therefore, the armrest 52 can be used even when the seat 10 takes either the 1 st or 2 nd forms without changing the vertical distance between the seat 10 and the armrest 52. Therefore, the convenience of the exercise assisting device 1 can be improved. In embodiments 2 to 5, the same modifications are also true.

The shape of the seat surface 10A of the intermediate portion 11 can be arbitrarily changed. In one example, the seating surface 10A of the intermediate portion 11 constitutes a plane.

The shape of the width of the intermediate portion 11 can be arbitrarily changed. In example 1, the width of the intermediate portion 11 is constant. In example 2, the width of the intermediate portion 11 increases from the rear side to the front side of the seat portion 10.

The shape of the width of the front portion 11A can be arbitrarily changed. In example 1, the width of the front portion 11A is constant. In example 2, the width of the front portion 11A is wider than the width of the rear portion 11B. In example 3, the width of the front portion 11A increases from the rear side to the front side of the seat 10.

The switching portion 20 of the modification includes another mechanism capable of displacing the intermediate portion 11 in the vertical direction instead of the seat airbag 40. An example of another mechanism is a ball screw.

The relationship between the height of the seating surface 10A of the intermediate portion 11 in the 1 st form and the height of the seating surface 10A of the intermediate portion 11 in the 2 nd form can be arbitrarily changed. In example 1, the height of the seating surface 10A of the intermediate portion 11 in the 2 nd form is substantially the same as the height of the seating surface 10A of the intermediate portion 11 in the 1 st form. In example 2, the height of the seating surface 10A of the intermediate portion 11 in the 2 nd form is lower than the height of the seating surface 10A of the intermediate portion 11 in the 1 st form.

Whether or not the pair of side portions 12 in the 2 nd aspect take the inclined posture can be arbitrarily changed. In one example, the pair of side portions 12 in the 2 nd form takes a posture in which they extend substantially downward. That is, the seat surface 10A of the intermediate portion 11 in the 2 nd form and the seat surfaces 10A of the pair of side portions 12 in the 2 nd form are substantially perpendicular to each other.

When the form of the seat portion 10 is the 2 nd form, the drive portion 70 of the modification swings the seat portion 10, and when the form of the seat portion 10 is the 1 st form, the drive portion 70 of the modification does not swing the seat portion 10.

The exercise assisting device 1 according to embodiment 1 can be configured such that at least one of the back support portion 13, the backrest 51, the armrests 52, the back airbag 61, and the holding airbag 62 is omitted. In embodiments 2 to 5, the same modifications are also true.

The seat 10 may be selected from a plurality of forms including at least 1 additional form in addition to the 1 st form and the 2 nd form. In one example, the plurality of forms further include any form configured in the process of deforming the seat portion 10 from the 1 st form to the 2 nd form.

In the above embodiment, as shown in fig. 1, the left and right holding airbags 62 are disposed above the armrests 52, but when it is desired to hold the pelvis and the vicinity of the buttocks from the left and right, the holding airbags 62 may be disposed closer to the center or lower side of the armrests 52 than in fig. 1.

In the above embodiment, the left and right holding airbags 62 are disposed on the armrests 52, but a configuration in which they are disposed on the seat portion 10 is also conceivable. With the above-described structure, the periphery of the pelvis and the waist of the user can be held in the seat mode. In the case of the above-described configuration, the exercise assisting device 1 according to the present embodiment can be used as a normal chair having the backrest 51 without the armrest 52 in a state of being in neither the seat mode nor the horse riding mode.
