And the switching part 20 selects a 2nd form by operating the intermediate part 11 and a pair of side part 12 with the deformation | transformation of the link 30 (refer FIG. 3).

  With reference to FIG. 7, an example of the structure of the drive part 70 is demonstrated. Since the specific configuration and operation of the drive unit 70 are substantially the same as those of the drive device disclosed in Japanese Patent Laid-Open No. 2006-61672, a part or all of the description of the common matters is omitted. FIG. 7 shows the seat 10 in a simplified manner.

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

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

  The function of the eccentric rod 76 is to displace the swing base 71 in the width direction of the seat portion 10. The eccentric rod 76 is connected to the output shaft of the first motor 73 via a plurality of rotating shafts and gears (not shown). One end of the eccentric rod 76 is connected to a rotating shaft that rotates eccentrically with the rotation of the output shaft of the first motor 73, and the other end is connected to one support plate 72.

  For example, the drive unit 70 is 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. For this reason, the seat portion 10 swings so as to form a substantially V shape in plan view. The drive unit 70 shifts the phase of the crank arm 74 by 90 ° with respect to the phase of the eccentric rod 76 so that the ratio between the rotational speed of the crank arm 74 and the rotational speed of the eccentric rod 76 is 2: 1. It may be configured as follows. In this example, the seat 10 swings so as to form an approximately eight shape in plan view. The drive unit 70 may be configured such that the ratio of the rotational speed of the crank arm 74 and the rotational speed of the eccentric rod 76 is 1: 2.

As the output shaft of the first motor 73 rotates, the crank arm 74 rotates eccentrically via the plurality of rotating shafts and gears, and one end of the eccentric rod 76 is eccentrically connected via the plurality of rotating shafts and gears. Rotate. The crank arm 74 transmits the rotational motion to the connecting link 75, whereby the connecting link 75 is displaced in the front-rear direction of the seat portion 10. For this reason, the swing base 71 is displaced in the front-rear direction of the seat part 10 via the connecting link 75, and the seat part 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 portion 10 by rotating eccentrically. As a result, the support plate 72 is inclined and the connecting link 75 is displaced in the width direction of the seat portion 10. For this reason, the swing base 71 is displaced in the width direction of the seat portion 10 via the connecting link 75, and the seat portion 10 is displaced in the width direction. In this way, the seat 10 swings in the front-rear direction and the width direction as the output shaft of the first motor 73 rotates. For this reason, a rocking motion is provided to the user 100 (see FIG. 9) who uses the exercise assisting device 1.

  The exercise assisting apparatus 1 further includes an elevating mechanism 80. The raising / lowering mechanism 80 is provided in the front side of the seat part 10, for example. The function of the lifting mechanism 80 is to change the inclination of the seat portion 10 in the front-rear direction. The lifting mechanism 80 includes a second motor 81 and a telescopic part 82. The expansion / contraction part 82 includes, for example, a ball screw (not shown). The stretchable part 82 has one end connected to the swing base 71 and the other end connected to one support plate 72. An output shaft (not shown) of the second motor 81 is connected to a ball screw nut via a worm gear (not shown) or the like.

  When the output shaft of the second motor 81 rotates, the nut of the ball screw rotates via the worm gear or the like, and the screw shaft of the ball screw is displaced in the vertical direction. For this reason, the expansion / contraction part 82 expands and contracts, and the front of the swing base 71 rotates around the connection shaft 77 between the swing base 71 and the connection link 75. For this reason, the inclination of the swing base 71 in the front-rear direction of the seat part 10 is changed, and the inclination of the seat part 10 in the front-rear direction is changed. The lifting mechanism 80 is driven based on the operation of the controller 54 (see FIG. 1).

  With reference to FIG. 8 and FIG. 9, an example of the use state of the exercise assistance apparatus 1 is demonstrated.

  The user 100 using the exercise assisting apparatus 1 operates the controller 54 to select either the first form or the second form.

It is easy to sandwich the pair of side portions 12 between the thighs. For this reason, when rocking exercise is performed using the exercise assisting device 1, the posture of the user 100 is easily stabilized. Moreover, according to the exercise assistance apparatus 1, since the width | variety of the intermediate part 11 becomes narrow as it goes to the front side from the back side of the seat part 10, the user 100 straddling the seat part 10 which takes a 2nd form is intermediate part 11 Is easily pinched with the thigh.

  According to the exercise assisting apparatus 1, the front part 11A is swollen above the rear part 11B. On the other hand, when the user 100 straddles the seat portion 10 taking the second form, for example, the buttocks are supported by the rear portion 11B, and the front portion 11A is positioned in front of the body. For this reason, even if rocking exercise is performed using the exercise assisting device 1, the body position with respect to the seat portion 10 is prevented from moving forward by the swelling of the front portion 11A. For this reason, when the swing motion is performed using the exercise assisting apparatus 1, the posture of the user 100 is more stable.

  When the foot of the user 100 straddling the seat portion 10 taking the second form is floating from the floor, the user's 100 motion associated with the swing motion of the seat portion 10 is not supported by the foot. Become. On the other hand, according to the exercise assisting apparatus 1, since the height of the seat portion surface 10 </ b> A of the intermediate portion 11 in the second form is set to be higher than that in the first form, the seat that takes the second form. The user's 100 legs straddling the part 10 are likely to float off the floor. For this reason, the effect given to the user 100 with the rocking | fluctuation movement of the seat part 10 is heightened.

  When the user 100 straddles the seat 10 taking the second form, the back support 13 can be used to determine the position of the waist. Since the back support unit 13 supports the waist or buttocks of the user 100, the position of the user's 100 waist in the seat 10 is stable, and the posture of the user 100 is likely to be stable when the seat 10 swings.

  The pair of armrests 52 are shaped such that, for example, the upper portion projects forward and the lower portion retracts rearward in the front-rear direction of the seat portion 10. For this reason, when the user 100 straddles the seat part 10 which takes a 2nd form, the leg of the user 100 does not contact the armrest 52 easily. For this reason, it is possible to smoothly straddle the seat 10 taking the second form, and even when the seat 10 swings, the leg of the user 100 is unlikely to contact the armrest 52.

  In the link 30 of the exercise assisting device 1, the length of the first side link 32A is longer than the length of the second side link 32B. In this case, the inclination of the first side link 32A with respect to the intermediate link 31 becomes large when the seat airbag 40 is inflated most. For this reason, the inclination of the pair of side portions 12 with respect to the intermediate portion 11 is increased, and the pair of side portions 12 can be easily sandwiched between the thighs in a state where the user 100 straddles the seat portion 10. For this reason, when the swing motion is performed using the exercise assisting apparatus 1, the posture of the user 100 is more likely to be stabilized.

  The direction of the user 100 sitting on the seat 10 when the exercise assisting device 1 takes the first form is the same as the direction of the user 100 straddling the seat 10 when the exercise assisting device 1 takes the second form. It is. For this reason, according to the exercise assistance apparatus 1, in the state in which the user 100 held the posture seated on the seat portion 10 or the posture straddling the seat portion 10, the first mode and the second mode can be switched. For this reason, the convenience of the exercise assistance apparatus 1 is improved.

  The rotational speed of the first motor 73 at this time (in other words, the swing speed of the seat portion) is C (rotation / minute). Further, the rotational speed C of the first motor 73 in step S35 is faster than the rotational speed B of the first motor 73 in step S31.

  Note that the control unit 500 may execute the process of step S35 after the process of step S36.

  As described above, in this embodiment, when the controller 500 determines that there is a mode change instruction operation from the controller 54 (for example, a change from the chair mode to the jober mode, or a change from the jober mode to the chair mode). ), The mode is changed while lowering the rotational speed of the first motor 73 (swinging speed of the seat).

  For this reason, compared with the case where the mode is changed after stopping the swinging operation, the user can feel that the stretch by swinging of the seat portion 10 is continuously performed. In addition, since the swinging speed of the seat is reduced, the mode can be changed safely.

  Moreover, in this embodiment, in step S10-step S13, the seat part 10 rock | fluctuates in the state which the left and right holding airbag 62 inflated in the chair mode. As described above, the seat 10 swings while the holding air bag 62 holds the pelvis and the vicinity of the waist from the left and right, so that the pelvis and the vicinity of the waist can be effectively stretched.

  Further, since the pelvis and the waist are fixed by the left and right holding airbags 62, the user can continue to ride the seat 10 in a stable state even when the seat 10 swings. But it has a remarkable effect.

  Further, in the present embodiment, in step S19 and step S21, the seat portion 10 is placed in a horizontal state, and then the air in the seat portion airbag 40 or the holding airbag 62 is exhausted to end the chair mode or the jover mode. It was. For this reason, the user can use the exercise assisting device as a normal chair when the exercise assisting device is not operating.

  The sixth embodiment may be modified as shown below.

  In the present embodiment, in step S13, the motor rotation speed (swinging speed of the seat) A in the chair mode or the jover mode, and in the chair mode or the jober mode after completion of the increase in the rotation speed in steps S28 and S36. The rotation speed (swinging speed) C of the motor may be the same, or the rotation speed A and the rotation speed C may be different.

  In the present embodiment, the control unit 500 is configured to increase the rocking speed in step S28 when it is determined in step S27 that 10 seconds have elapsed since the start of measuring the predetermined time in step S26. This timing is not limited to step S26, and timing may be started at the timing when the swing speed is lowered, when the air in the holding airbag 62 is exhausted, or when the air is supplied to the seat airbag 40. good. Further, although the predetermined time in step S27 is 10 seconds, it is not limited to 10 seconds.

  In the present embodiment, the control unit 500 is configured to increase the rocking speed in step S36 when it is determined in step S34 that 10 seconds have elapsed since the start of measuring the predetermined time in step S33. This timing is not limited to step S33, and timing is started at the timing when the swing speed is lowered, the timing when air is supplied into the holding airbag 62, and the timing when the air in the seat airbag 40 is exhausted. Also good. Moreover, although the predetermined time in step S34 is 10 seconds, it is not limited to 10 seconds.

  In the present embodiment, the configuration is such that the user operates the controller 54 to switch between the jobber mode and the chair mode. However, the configuration may be such that the jober mode and the chair mode are automatically switched in a series of courses. In this case, for example, in step S10 and step S16 in FIG. 16, the storage unit 503 determines whether the control unit 500 performs the next mode to be executed in the jober mode or the chair mode in a certain course. Can be determined based on data (for example, a flag) stored in.

  In the present embodiment, the left and right holding airbags 62 are disposed above the armrests 52 as shown in FIG. 1, but when it is desired to hold the pelvis or the vicinity of the buttocks from the left and right, compared to FIG. The holding airbag 62 may be disposed at the center or below.

  In the present embodiment, the left and right holding airbags 62 are arranged on the armrests 52, but it is also conceivable that the left and right holding airbags 62 are arranged on the seat portion 10. Even in such a configuration, the user's pelvis and waist area can be held in the chair mode. Moreover, when it is set as such a structure, the exercise assistance apparatus 1 of this embodiment can be used as a normal chair without the armrest 52 and the backrest 51 in the state which is not a chair mode or a jover mode.

The swing speed of the seat portion 10 may be configured to suddenly slow down or increase the swing speed of the seat portion 10, but may be gradually slowed down or fastened, gradually slowed down or fastened. You may do it. The seat 10 is preferably changed gradually or stepwise. This is because it is possible to avoid the user from being surprised as much as possible by a sudden change in the swing speed of the seat portion 10.
(Embodiment 7)
Next, a seventh embodiment will be described.

  The difference between the sixth embodiment and the seventh embodiment is that, in the sixth embodiment, the control unit 500 starts measuring a predetermined time in step S26, and when 10 seconds elapses in step S27, the swing speed is changed in step S28. When it is determined that 30 seconds have elapsed in step S29, the seat portion air is held in step S30. However, in the seventh embodiment, the predetermined time is counted with the start of air supply to the seat portion airbag 40 (for example, 40 seconds), and when the predetermined time has elapsed, the rocking speed is increased.

  That is, step S24 to step S30 in FIG. 16 which is a flowchart of the sixth embodiment is different from step S124 to step S129 in FIG. 17 which is a flowchart of the seventh embodiment, and other steps are the same. Therefore, the description of the same part is omitted.

  More specifically, steps S10 to S22 in FIG. 16 are the same operations as steps S110 to 122 in FIG. 17, and steps S31 to S36 in FIG. 16 are the same operations as steps S130 to S135 in FIG.

  The block diagram of the seventh embodiment and the block diagram of the sixth embodiment are the same.

  In step S124 of FIG. 17, the control unit 500 decreases the rotation speed of the first motor 73 (swinging speed of the seat), and proceeds to step S125.

  The rotational speed of the first motor 73 at this time (in other words, the rocking speed of the seat portion) is B (rotation / minute). Further, the rotational speed of the first motor 73 in step S124 is slower than the rotational speed A of the first motor 73 in step S113.

  In step S125, the control unit 500 controls the third electromagnetic valve 506 and the fourth electromagnetic valve 507 to start the exhaust of the air in the holding airbag 62, and for a predetermined time (for example, 4 seconds). Start timing.

  In step S126, the controller 500 drives the pump when the timing of 4 seconds started in step S125 is completed, and controls the first electromagnetic valve 504 to supply air to the seat airbag 40. Start. In addition, timing of a predetermined time (for example, 40 seconds) is started.

In step S127, if control unit 500 determines that the counting of a predetermined time (for example, 40 seconds) has ended after the start of timing in step S126, the process proceeds to step S128.

  In step S128, the controller 500 holds the air in the seat airbag 40 by controlling the holding valve 600.

  In step S129, the controller 500 increases the rotational speed of the first motor 73, and returns the process to step S116.

  The seventh embodiment may be modified as described below.

  In the present embodiment, the control unit 500 is configured to retain air in step S128 when it is determined in step S127 that 40 seconds have elapsed since the start of measuring a predetermined time (for example, 40 seconds) in step S126. The timing for starting the time measurement is not limited to step S126, but the timing at which the swing speed is lowered (step S124), the timing at which the air in the holding airbag 62 is exhausted (step S125), and the seat airbag 40 are displayed. The timing may be started at the timing of supplying air (step S126). Further, although the predetermined time in step S127 is 40 seconds, it is not limited to 40 seconds.

  In this embodiment, in step S113, the motor rotation speed (swinging speed of the seat) A in the chair mode or the jobber mode, and the chair mode or the jober mode after completion of the increase in the rotation speed in steps S129 and S135. The rotation speed (swinging speed) C of the motor may be the same, or the rotation speed A and the rotation speed C may be different.

  In the present embodiment, the control unit 500 is configured to hold air in step S134 when it is determined in step S133 that 10 seconds have elapsed since the control unit 500 started counting the predetermined time in step S132. The timing is not limited to step S131, and the timing may be started at the timing when the swing speed is lowered, when the air is supplied into the holding airbag 62, or when the air in the seat airbag 40 is exhausted. good. Further, although the predetermined time in step S133 is 10 seconds, it is not limited to 10 seconds.

  In the present embodiment, the configuration is such that the user operates the controller 54 to switch between the jobber mode and the chair mode. However, the configuration may be such that the jober mode and the chair mode are automatically switched in a series of courses. In this case, for example, in step S110 and step S116 of FIG. 17, the storage unit 503 indicates whether the control unit 500 performs the next mode to be performed in the jober mode or the chair mode in a series of courses. Can be determined based on data (for example, a flag) stored in.

  In the present embodiment, the left and right holding airbags 62 are disposed above the armrests 52 as shown in FIG. 1, but when it is desired to hold the pelvis or the vicinity of the buttocks from the left and right, compared to FIG. The holding airbag 62 may be disposed at the center or below.

  In the present embodiment, the left and right holding airbags 62 are arranged on the armrests 52, but it is also conceivable that the left and right holding airbags 62 are arranged on the seat portion 10. Even in such a configuration, the user's pelvis and waist area can be held in the chair mode. Moreover, when it is set as such a structure, the exercise assistance apparatus 1 of this embodiment can be used as a normal chair without the armrest 52 and the backrest 51 in the state which is not a chair mode or a jover mode.

The swing speed of the seat portion 10 may be configured to suddenly slow down or increase the swing speed of the seat portion 10, but may be gradually slowed down or fastened, gradually slowed down or fastened. You may do it. The seat 10 is preferably changed gradually or stepwise. This is because it is possible to avoid the user from being surprised as much as possible by a sudden change in the swing speed of the seat portion 10.
(Embodiment 8)
Next, an eighth embodiment will be described.

  The difference between the eighth embodiment and the sixth and seventh embodiments is that in the sixth and seventh embodiments, the mode is changed while the seat portion 10 is swung, but in the eighth embodiment, the seat portion is temporarily changed. The difference is that the mode is changed after 10 becomes horizontal.

  Therefore, the block diagrams are the same in the sixth and seventh embodiments and the eighth embodiment. On the other hand, with respect to the flowchart, steps S224 to S233 of FIG. 18 which are the flowchart of the eighth embodiment are different from the flowcharts of FIGS. 16 and 17, and the other steps are the same as those of the sixth and seventh embodiments. Since they are the same, description of the same parts is omitted.

  In step S224 of FIG. 18, the control unit 500 drives the first motor 73 until the output from the first position sensor 501 becomes an output in a state where the seat 10 is in the horizontal position. Keep it level.

  When the seat portion 10 is tilted in the front-rear direction, the second motor 81 is driven so that the output from the second position sensor 502 becomes an output in a state where the seat portion 10 is in the horizontal position. Until this occurs, the second motor 81 is driven to bring the seat 10 into a horizontal state.

  In step S225, the control unit 500 controls the third electromagnetic valve 506 and the fourth electromagnetic valve 507 to exhaust the air in the left and right holding airbags 62.

  In step S <b> 226, the controller 500 starts the supply of air to the seat airbag 40 by driving the air pump 41 and controlling the first electromagnetic valve 504.

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

  In step S <b> 228, the control unit 500 controls the first motor 73 to start the swinging operation of the seat unit 10 and returns the process to step 216.

  In step S229 in FIG. 18, the control unit 500 drives the first motor 73 and moves the seat unit 10 horizontally until the output from the first position sensor becomes an output in a state where the seat unit 10 is in the horizontal position. To make sure

  When the seat 10 is tilted in the front-rear direction, the second motor 81 is driven so that the output from the second position sensor becomes the output when the seat 10 is in the horizontal position. The second motor 81 is driven until the seat 10 is in a horizontal state.

  In step S <b> 230, the control unit 500 controls the first electromagnetic valve 504 to exhaust the air in the seat airbag 40.

  In step S231, the control unit 500 starts supplying air to the left and right holding airbags 62 by controlling the third solenoid valve 506 and the fourth solenoid valve 507.

In step S232, the control unit 500 holds the air pressure of the holding airbag 62.

  In step S <b> 233, the control unit 500 starts the swinging operation of the seat unit 10 by controlling the first motor 73.

  As described above, in the eighth embodiment, when the mode is changed, the seat portion airbag 40 or the holding airbag 62 is exhausted or supplied after the seat portion 10 is once made horizontal.

  For this reason, the user can recognize that the mode is changed once the body 10 senses that the seat portion 10 has become horizontal.

  In addition, when the chair mode and the jover mode are executed for a long time, the user can take a break while the seat portion 10 is in a horizontal state for a short time.

  The eighth embodiment may be modified as shown below.

  In the present embodiment, the configuration is such that the user operates the controller 54 to switch between the jobber mode and the chair mode. However, the configuration may be such that the jober mode and the chair mode are automatically switched in a series of courses. In this case, for example, in step S210 and step S216 in FIG. 18, the storage unit 503 indicates whether the control unit 500 performs the next mode to be executed in the jober mode or the chair mode in a series of courses. Can be determined based on data (for example, a flag) stored in.

  In the present embodiment, the left and right holding airbags 62 are disposed above the armrests 52 as shown in FIG. 1, but when it is desired to hold the pelvis or the vicinity of the buttocks from the left and right, compared to FIG. The holding airbag 62 may be disposed at the center or below.

In the present embodiment, the left and right holding airbags 62 are arranged on the armrests 52, but it is also conceivable that the left and right holding airbags 62 are arranged on the seat portion 10. Even in such a configuration, the user's pelvis and waist area can be held in the chair mode. Moreover, when it is set as such a structure, the exercise assistance apparatus 1 of this embodiment can be used as a normal chair without the armrest 52 and the backrest 51 in the state which is not a chair mode or a jover mode.
(Embodiment 9)
Next, Embodiment 9 will be described.

  The block diagram of the ninth embodiment is the same as that shown in FIG.

  Moreover, since the exercise assistance apparatus 1 of Embodiment 9 is the same as the structure of any exercise assistance apparatus 1 of Embodiment 1-8 demonstrated previously, description is abbreviate | omitted.

  FIG. 19 is a diagram illustrating a usage example of the exercise assistance device 1 according to the ninth embodiment.

  In the present embodiment, the control unit 500 controls the first motor 73 to maintain the state where the exercise assisting device is tilted to the left side or the right side. In this state, the user stretches the upper body by twisting the upper body to the right when the exercise assisting device is tilted to the left, and twisting the upper body, particularly near the waist, when the exercise assisting device is tilted to the right. Can be done. The exercise assisting apparatus 1 as the apparatus of the present embodiment enables the user to stretch the flank, particularly the oblique oblique muscle.

  First, as shown in FIG. 19A, the user sits on the seat portion 10. At this time, the left and right holding airbags 62 are not inflated.

  Subsequently, when the user performs an operation to execute the operation of the ninth embodiment, the control unit 500 determines from the controller 54 that there is an instruction operation to execute the operation of the ninth embodiment, and The left and right holding airbags 62 are inflated by controlling the third solenoid valve 506 and the fourth solenoid valve 507.

Subsequently, the control unit 500 controls the first motor 73 to first bring the seat portion 10 to the right side at a predetermined angle as shown in FIG. 19B and maintain this state.
At this time, a voice such as “Please extend your back and raise your right arm up” is sent from a speaker (not shown), and then a voice like “Please bend your right arm to the left and tilt your upper body to the left” from the speaker. Is sent out. In this way, the user is notified of the stretching operation procedure from the speaker. When the user follows this notification, as shown in FIG. 16C, the user tilts his / her body to the left side.

  In this way, the user can perform stretching to stretch the right flank.

  Subsequently, a stretch that stretches the left flank can be performed in the same manner.

  The control unit 500 controls the first motor 73 so that the seat 10 is first inclined to the left by a predetermined angle, and this state is maintained. At this time, a speaker such as “Please extend your back and raise your left arm” is sent out from a speaker (not shown), and then from the speaker, “Please bend your left arm to the right and tilt your upper body to the right”. Is sent out. In this way, the user is notified of the stretching operation procedure from the speaker. When the user follows this notification, the user is tilted to the right.

  Thus, by tilting the seat portion 10 alternately to the right side and the left side, the user can stretch the flank.

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

  If the controller 500 determines from the controller 54 that there is an operation for executing the operation of the ninth embodiment, whether or not the current device is in the chair mode from the data (for example, flag) stored in the storage unit 503. If it is determined whether the mode is the jobber mode and the mode is the chair mode, the first motor 73 is controlled so that the seat portion 10 is inclined to the right or left by a predetermined angle, and the state is maintained. It is.

  On the other hand, if the control unit 500 determines that it is in the jobber mode, the control unit 500 prohibits the seat unit 10 from being inclined at a predetermined angle to the right side or the left side, or controls the first electromagnetic valve 504 to control the seat unit. After the air in the airbag 40 is exhausted to make the seat 10 substantially flat with respect to the floor surface, the left and right holding airbags 62 are inflated, and the seat 10 is tilted to the right or left by a predetermined angle.

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

Further, the timing for outputting the instruction voice for stretching from the speaker may be in the middle of the movement of the seat 10 so that it is tilted, or may be when the seat 10 is in a tilted state.

  Further, in a state where the seat portion 10 is tilted to the right side or the left side, an operation in which a part of the seat portion 10 is raised may be prohibited. This is because if a part of the seat part 10 is raised while the seat part 10 is tilted, the user may fall depending on the degree of inclination of the seat part 10.

  Embodiment 9 can be described as follows.

  The exercise assisting device 1 according to the ninth embodiment includes a swingable seat portion 10 and a backrest 51, and can maintain a state in which the seat portion 10 is inclined at a predetermined angle on the right side or the left side.

  In addition, the first mode in which the seat portion 10 swings in a state where a part of the seat portion 10 is raised, the state in which the seat portion 10 is not raised, or the height of a portion of the seat portion 10 is raised. A second mode in which the seat portion 10 swings in a state lower than the first mode, and in the second mode, the seat portion 10 is inclined at a predetermined angle to the right or left side. It can be maintained.

  In the second mode, the swinging of the seat portion 10 may be prohibited in a state in which the seat portion 10 is tilted at a predetermined angle to the right or left.

  In the first mode, an operation for maintaining the state in which the seat portion 10 is inclined at a predetermined angle to the right side or the left side may be prohibited.

Further, in the first mode, the seat portion 10 may be prohibited from tilting to the right side or the left side. (Embodiment 10)
Next, Embodiment 10 will be described.

  The block diagram of the tenth embodiment is the same as the diagram shown in FIG.

  Moreover, since the exercise assistance apparatus 1 of Embodiment 10 is the same as the structure of the exercise assistance apparatus 1 of any one of Embodiments 1-9 demonstrated previously, description is abbreviate | omitted.

  In the present embodiment, the control unit 500 controls the second motor 81 so that the user performs stretching in a state where the seat unit 10 is inclined forward or backward by a predetermined angle. For example, the user can perform an abdominal muscle exercise or exercise to extend the back muscles by extending both hands while being inclined forward or backward.

  More specifically, when the controller 500 determines from the controller 54 that there is a predetermined operation, the controller 500 controls the second motor 81 to place the seat 10 forward or backward at a predetermined angle. , To maintain that state.

  At this time, a notification is given from a speaker (not shown) to the user to perform stretching. For example, a voice for instructing stretching such as “Let your legs stretch while stretching your back” is output from the speaker.

  The predetermined angle is, for example, about 10 to 25 degrees backward or forward with respect to the floor surface, and the seat 10 is maintained in an inclined state at this angle. The predetermined angle is not limited to this angle.

Further, when the controller 500 determines from the controller 54 that there is a predetermined operation, the controller 500 determines from the data (for example, a flag) stored in the storage unit 503 whether the current device is in the chair mode or the jober mode. And if it determines with it being a chair mode, it is good also as a structure which makes the seat part 10 incline in the predetermined angle forward or back by controlling the 2nd motor 81, and maintains the state.

  On the other hand, when the control unit 500 determines that the mode is the jover mode, the control unit 500 prohibits the seat unit 10 from being inclined at a predetermined angle forward or backward, or controls the first electromagnetic valve 504 to control the seat unit. The air in the airbag 40 may be exhausted to make the seat portion 10 in a substantially flat state, and then the seat portion 10 may be inclined forward or backward at a predetermined angle.

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

  The tenth embodiment can be described as follows.

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

  In addition, the first mode in which the seat portion 10 swings in a state where a part of the seat portion 10 is raised, the state in which the seat portion 10 is not raised, or the height of a portion of the seat portion 10 is raised. A second mode in which the seat 10 swings in a state lower than the first mode, and the seat 10 is tilted forward or backward at a predetermined angle in the second mode. Can be maintained.

  In the second mode, the swing of the seat portion 10 is prohibited in a state where the seat portion 10 is tilted forward or backward at a predetermined angle.

  Further, in the first mode, an operation for maintaining the state in which the seat portion 10 is inclined at a predetermined angle forward or backward is prohibited.

Further, in the first mode, it is prohibited to incline the seat portion 10 forward or backward.
(Embodiment 11)
The eleventh embodiment is such that, in each of the embodiments described so far, when the user finishes using the exercise assisting apparatus 1, the exercise assisting apparatus 1 is shaped to the user's preference.

  More specifically, when the exercise assisting apparatus 1 swings in the jover mode or the chair mode and the user performs an operation to end these modes, the seat 10 is set at an angle set in advance by the user. It stops in a tilted state.

  Details will be described below. When the exercise assisting device 1 is in the standby state or the jover mode or the chair mode, the control unit 500 determines that there is an operation for setting the angle of the seat 10 at the end of the jober mode or the chair mode from the controller 54. Based on an operation from the controller 54, information on the angle of the seat 10 is stored in the storage unit 503.

  At this time, in the storage unit 503, the seat 10 is tilted forward 10 degrees, tilted forward 5 degrees, horizontal with respect to the floor (tilt angle 0), and tilted rear 5 degrees. Information of any of the five levels of the angle and the angle tilted 10 degrees backward is stored.

  This angle is an example, and the angle and the number of steps may be changed as appropriate.

When the user uses the exercise assisting device 1 in the jober mode or the chair mode, and the control unit 500 determines that there is an operation for terminating the use of the exercise assisting device 1 from the controller 54, the operation is stored in the storage unit 503. Information on the angle at which the seat 10 tilts is read, and the second motor 81 is controlled so that the seat 10 is at the read angle.

  With such a configuration, the user can sit with the seat portion 10 tilted to a desired angle when using the exercise assisting apparatus 1 as a chair in a standby state.

  In the standby state, when the controller 500 determines that there is an operation of tilting the seat 10 from the controller 54, the controller 500 tilts the seat 10 to an angle desired by the user by controlling the second motor 81. Anyway.

  By setting it as such a structure, the user can incline the seat part 10 to a desired angle in a standby state, and can use the exercise assistance apparatus 1 as a reclining chair.

  Further, the control unit 500 stores the angle of the seat 10 in the standby state immediately before starting the jobber mode or the chair mode in the storage unit 503 automatically or based on the user's operation, and the jobber mode or the chair mode is stored. Control may be performed to tilt the seat 10 so that the angle is stored in the storage unit 503 when the process ends and shifts to the standby state.

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

(Modification)
The above description of each embodiment is an example of the form that the exercise assisting device according to the present invention can take, and is not intended to limit the form. In addition to the above-described embodiments, the exercise assisting device according to the present invention may take a form in which, for example, modifications of the embodiments shown below and at least two modifications not contradicting each other are combined.

  As shown in FIG. 14, the armrest 52 of the modification of the first embodiment can be displaced in the vertical direction in conjunction with the intermediate portion 11. Specifically, the armrest 52 is displaced in the vertical direction with respect to the backrest 51 in conjunction with the vertical displacement of the intermediate portion 11 caused by the inflation or deflation of the seat airbag 40. The armrest 52 is displaced in the vertical direction by, for example, a motor. For this reason, the distance between the seat portion 10 and the armrest 52 in the vertical direction does not change, and the armrest 52 can be used even when the seat portion 10 takes either the first form or the second form. is there. For this reason, the convenience of the exercise assistance apparatus 1 is improved. Note that similar modifications are also established in the second to fifth embodiments.

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

  The shape of the width of the intermediate portion 11 can be arbitrarily changed. In the first example, the width of the intermediate portion 11 is constant. In the second example, 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 the first example, the width of the front portion 11A is constant. In the second example, the width of the front portion 11A is wider than the width of the rear portion 11B. In the third example, the width of the front portion 11A becomes wider from the rear side of the seat portion 10 toward the front side.

The switching unit 20 of the modified example includes another mechanism that can displace the intermediate unit 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 seat portion surface 10A of the intermediate portion 11 in the first form and the height of the seat portion surface 10A of the intermediate portion 11 in the second form can be arbitrarily changed. In the first example, the height of the seat portion surface 10A of the intermediate portion 11 in the second embodiment is substantially the same as the height of the seat portion surface 10A of the intermediate portion 11 in the first embodiment. In the second example, the height of the seat portion surface 10A of the intermediate portion 11 in the second form is lower than the height of the seat portion surface 10A of the intermediate portion 11 in the first form.

  Whether or not the pair of side portions 12 in the second embodiment takes an inclined posture can be arbitrarily changed. In one example, the pair of side portions 12 in the second form takes a posture that extends generally downward. That is, the seat portion surface 10A of the intermediate portion 11 in the second form and the seat portion surfaces 10A of the pair of side portions 12 in the second form constitute substantially vertical.

  The drive unit 70 according to the modified example swings the seat 10 when the form of the seat 10 is the second form, and does not swing the seat 10 when the form of the seat 10 is the first form. .

  The exercise assisting apparatus 1 according to the first embodiment may take a form in which at least one of the back support 13, the backrest 51, the armrest 52, the back airbag 61, and the holding airbag 62 is omitted. Note that similar modifications are also established in the second to fifth embodiments.

  The plurality of forms from which the seat 10 can be selected include at least one other form in addition to the first form and the second form. In one example, the plurality of forms further includes any form configured in the process in which the seat 10 is deformed from the first form to the second form.

  In the present embodiment, the left and right holding airbags 62 are disposed above the armrests 52 as shown in FIG. 1, but when it is desired to hold the pelvis or the vicinity of the buttocks from the left and right, compared to FIG. The holding airbag 62 may be disposed at the center or below.

  In the present embodiment, the left and right holding airbags 62 are arranged on the armrests 52, but it is also conceivable that the left and right holding airbags 62 are arranged on the seat portion 10. Even in such a configuration, the user's pelvis and waist area can be held in the chair mode. Moreover, when it is set as such a structure, the exercise assistance apparatus 1 of this embodiment can be used as a normal chair without the armrest 52 and the backrest 51 in the state which is not a chair mode or a jover mode.

  The exercise assistance device according to the present invention can be used for various exercise assistance devices including home use and business use.
