For this reason, a reference state (see FIG. 8D) is formed. When the right high state is changed to the right rear high state, the relationship between the height position of the front end portion of the right sciatic support portion 23 and the height position of the rear end portion of the right sciatic support portion 23 is changed.

  When a predetermined period has elapsed from time t15, that is, time t14, the control unit 60 switches between the third electromagnetic valve 53 and the fourth electromagnetic valve 54. Thereby, the left front airbag 33A, the left rear airbag 33B, and the air pump 57 are connected to each other. For this reason, the left front airbag 33A and the left rear airbag 33B are inflated by intake air. For this reason, the left height state (refer FIG.8 (e)) in which the left side seat surface is lower than the right side seat surface is formed.

  When a predetermined period has elapsed from time t16, that is, from time t15, the control unit 60 switches the third electromagnetic valve 53. Thereby, the left front airbag 33A is connected to the exhaust passage 58. For this reason, the left front airbag 33A contracts due to natural exhaust. For this reason, the left rear high state in which the left and front seat surfaces formed by the left front airbag 33A are lower than the left and rear seat surfaces formed by the left rear airbag 33B (see FIG. 8F). Is formed. When the left high state is changed to the left rear high state, the relationship between the height position of the front end portion of the right sciatic support portion 23 and the height position of the rear end portion of the right sciatic support portion 23 is changed.

  When a predetermined period has elapsed from time t17, that is, from time t16, the control unit 60 switches the fourth electromagnetic valve 54. As a result, the left rear airbag 33B is connected to the exhaust passage 58. For this reason, the left rear airbag 33B contracts by natural exhaust. For this reason, the reference state (see FIG. 8A) is formed. After the time t17, the operation after the time t11 is repeatedly executed until the exercise end signal is output from the control unit 60 via the operation signal from the operation unit 70.

With reference to FIG. 8, the relationship between the operation of the pelvis exercise device 1 and the pelvis when the pelvic up / down mode is selected will be described.
As shown in FIG. 8 (a), when the pelvic exercise device 1 is in the reference state, the right and left sciatica are held symmetrically.

  As shown in FIG. 8 (b), when the pelvic exercise device 1 is in the right-high state, a force toward the upper YA acts on the right sciatic bone. At this time, the right ischia moves to a higher position than the left ischia. For this reason, stress is generated in the joint connecting the right pelvis and the left pelvis.

  As shown in FIG. 8C, when the pelvic exercise device 1 is in the right rear high state, a force toward the upper YA acts on the right sciatic bone. That is, the right sciatic support 23 formed by the right front airbag 23A and the right rear airbag 23B is inclined in the depth direction Z. At this time, the right rear sciatic bone moves to a position higher than the right front sciatic bone and the left sciatic bone. For this reason, stress is generated in the joint connecting the right pelvis and the left pelvis and in the right pelvis.

  As shown in FIG. 8 (e), when the pelvic exercise device 1 is in the left high state, a force toward the upper YA acts on the left ischia. At this time, the left ischia moves to a higher position than the right ischia. For this reason, stress is generated in the joint connecting the right pelvis and the left pelvis.

  As shown in FIG. 8F, when the pelvic exercise device 1 is in the left rear high state, a force toward the upper YA is acting on the left posterior ischia. In other words, the left sciatic support 33 formed by the left front airbag 33A and the left rear airbag 33B is inclined in the depth direction Z. At this time, the left rear sciatic bone moves to a position higher than the left front sciatic bone and the right sciatic bone. For this reason, stress is generated in the joint connecting the right pelvis and the left pelvis and in the left pelvis.

With reference to FIG. 9 and FIG. 10, an example of the operation | movement aspect of the pelvis exercise | movement apparatus 1 when the pelvis rotation mode is selected is demonstrated.
In the pelvic rotation mode, the solenoid valves 51 to 56 are sequentially switched. The first solenoid valve 51 and the second solenoid valve 52 are switched at the same timing. The third solenoid valve 53 and the fourth solenoid valve 54 are switched at the same timing.

  When the operation of the pelvic exercise device 1 is started based on the time t21, that is, based on the output from the operation unit 70, the control unit 60 drives the air pump 57. In addition, the control unit 60 switches the right front airbag 23A, the right rear airbag 23B, the left front airbag 33A, the left rear airbag 33B, the right common airbag 42, and the left common airbag through switching of the electromagnetic valves 51 to 56. 43 and the exhaust passage 58 are connected. Thereby, air is discharged from the right front airbag 23A, the right rear airbag 23B, the left front airbag 33A, the left rear airbag 33B, the right common airbag 42, and the left common airbag 43 by natural exhaust. For this reason, a reference rotation state (see FIG. 10A) in which the seat surface is in a reference state horizontal to the floor surface F and the phase in the rotation direction R of the turntable 41 (hereinafter referred to as “rotation phase”) is a reference phase is formed. The The reference phase corresponds to the phase of the turntable 41 when the right common airbag 42 and the left common airbag 43 contract and the connecting portion 45 is located at the center of the right stopper 44 and the left stopper 44. .

  When a predetermined period has elapsed from time t22, that is, from time t21, the control unit 60 switches the first electromagnetic valve 51, the second electromagnetic valve 52, and the sixth electromagnetic valve 56. Thereby, the right front airbag 23A, the right rear airbag 23B, the left common airbag 43, and the air pump 57 are connected to each other. For this reason, the right front airbag 23A, the right rear airbag 23B, and the left common airbag 43 are inflated by intake air. Therefore, a right rotation state (see FIG. 10B) is formed in which the seat surface is in a right-high state and the rotation phase of the turntable 41 is changed in the second rotation direction RB from the reference phase.

  When a predetermined period has elapsed from time t23, that is, from time t22, the control unit 60 switches the first electromagnetic valve 51, the second electromagnetic valve 52, and the sixth electromagnetic valve 56. As a result, the right front airbag 23A, the right rear airbag 23B, and the left common airbag 43 are connected to the exhaust passage 58. For this reason, the right front airbag 23A, the right rear airbag 23B, and the left common airbag 43 contract due to natural exhaust. For this reason, a reference state and a reference rotation state (see FIG. 10C) are formed.

  When a predetermined period has elapsed from time t24, that is, time t23, the control unit 60 switches the third electromagnetic valve 53, the fourth electromagnetic valve 54, and the fifth electromagnetic valve 55. Thereby, the left front airbag 33A, the left rear airbag 33B, the right common airbag 42, and the air pump 57 are connected to each other. For this reason, the left front airbag 33A, the left rear airbag 33B, and the right common airbag 42 are inflated by intake air. For this reason, the left rotation state (refer FIG.10 (d)) in which the rotation phase of the turntable 41 was changed to the 1st rotation direction RA rather than the reference | standard phase is formed.

  When a predetermined period has elapsed from time t25, that is, from time t24, the control unit 60 switches the third electromagnetic valve 53, the fourth electromagnetic valve 54, and the fifth electromagnetic valve 55. Thereby, the left front airbag 33A, the left rear airbag 33B, the right common airbag 42, and the exhaust passage 58 are connected to each other. For this reason, the left front airbag 33A, the left rear airbag 33B, and the right common airbag 42 contract due to natural exhaust. For this reason, the reference state (see FIG. 8A) is formed. After time t25, the operation after time t21 is repeatedly executed until an exercise end signal is output from the control unit 60 via an operation signal from the operation unit 70.

With reference to FIG. 10, the relationship between the operation of the pelvis exercise device 1 and the pelvis when the pelvic rotation mode is selected will be described.
As shown in FIG. 10 (a), when the pelvic exercise device 1 is in the reference state and the reference rotation state, the right and left sciatuses are symmetrical and the pelvis is kept facing the front ZA. Yes.

  As shown in FIG. 10 (b), when the pelvic exercise device 1 is in a right-high state and a right-rotating state, a force toward the upper YA is applied to the right ischia and a force to rotate in the second rotation direction RB is applied to the pelvis. It works. At this time, the right ischia moves to a higher position than the left ischia. For this reason, stress is generated in the joint connecting the right pelvis and the left pelvis. Further, when the user tries to maintain the posture, the pelvis rotates in the second rotation direction RB with respect to the portion of the trunk above the pelvis. For this reason, stress is generated in the joint connecting the pelvis and the spine.

  As shown in FIG. 10 (d), when the pelvis exercise device 1 is in the left high state and the left rotation state, a force toward the upper YA is applied to the left ischia and a force to rotate the pelvis in the first rotation direction RA. It works. At this time, the left ischia moves to a higher position than the right ischia. For this reason, stress is generated in the joint connecting the right pelvis and the left pelvis. Further, when the user tries to hold the posture, the pelvis rotates in the first rotation direction RA with respect to a portion of the trunk above the pelvis. For this reason, stress is generated in the joint connecting the pelvis and the spine.

The operation of the pelvis exercise device 1 will be described.
In the pelvic exercise device 1, the right sciatic support 23 and the left sciatic support 33 can operate separately. For this reason, forces in different directions on the right side and left side of the pelvis, or forces of different magnitudes can be applied even in the same direction. For this reason, the pelvic exercise device 1 can effectively give stimulation to the joints inside the pelvis and the muscles around the pelvis. Examples of joints in the pelvis include right and left sacroiliac joints and pubic joints.

  The pelvis exercise device 1 has an integral drive unit 40. For this reason, the application of force to the right and left sides of the pelvis and the application of force to the entire pelvis by the operations of the right sciatic support 23 and the left sciatic support 33 can be performed simultaneously. Therefore, various stimuli can be applied to the pelvis, joints related to the pelvis, and muscles around the pelvis.

  As shown in FIGS. 8A to 8F, in the pelvic up-and-down mode, the pelvic exercise device 1 is in the reference state, the right high state, the right rear high state, the reference state, the left high state, and the left rear high Repeat state. In other words, the right sciatic support 23 and the left sciatic support 33 operate alternately and symmetrically. For this reason, the pelvic exercise device 1 can prompt the pelvis to perform an operation similar to the operation of the so-called buttocks walking movement that advances by the operation of the pelvis while sitting on the floor. Ass walking exercise is said to be effective in correcting the pelvis. For this reason, the effect of correcting the pelvis can be expected.

  As shown in FIGS. 10A to 10D, in the pelvic rotation mode, the integrated drive unit 40 rotates the pelvis. For this reason, joints around the pelvis, for example, joints connecting the lumbar vertebra and the pelvis and muscles around the pelvis can be stimulated. For this reason, the effect which loosens the pelvic circumference can be expected.

  The pelvic exercise device 1 moves the pelvis. For this reason, the buttocks easily slide on the sciatic support portions 23 and 33. The pelvic exercise device 1 includes pelvic support portions 21 and 31. For this reason, the movement with respect to the pelvis support parts 21 and 31 of a buttocks and a pelvis is suppressed.

The pelvic exercise device 1 has the following effects.
(1) In the pelvic exercise device 1, the left sciatic support 33 and the right sciatic support 23 can operate separately. For this reason, the movement which shifted the right pelvis and the left pelvis can be performed. For this reason, the joint inside the pelvis and the muscle around the pelvis can be effectively exercised. The pelvic exercise device 1 can contribute to improvement of physical functions by effectively exercising joints inside the pelvis and muscles around the pelvis. For example, maintaining posture, improving walking movement, reducing left and right differences in muscles and movement, improving exercise ability, shaping the lower abdomen, improving cooling by promoting blood circulation in the trunk, and dysuria due to activation of the pelvic floor muscles Can contribute to improvement.

(2) In the pelvic exercise device 1, the right sciatic support 23 and the left sciatic support 33 operate alternately. For this reason, it is possible to cause the user to perform an exercise that reproduces the movement of the pelvis during walking.
(3) In the pelvic exercise device 1, the right sciatic support 23 and the left sciatic support 33 operate symmetrically. For this reason, the exercise | movement of the right pelvis and the exercise | movement of the left pelvis can be performed uniformly. For this reason, it can suppress that a difference arises in the training effect of the joint and muscle which are related to the exercise | movement of the right pelvis, and the joint and muscle which are related to the exercise | movement of the left pelvis.

  (4) In the pelvic exercise device 1, the right sciatic support 23 and the left sciatic support 33 move in the height direction Y (vertical direction). For this reason, it is possible to cause the user to perform an exercise that reproduces the fist up and down system, which are the daily operations of the pelvis.

  (5) In the pelvic exercise device 1, the right sciatic support 23 and the left sciatic support 33 are inclined forward ZA. For this reason, it is possible to make the user perform an exercise that reproduces the inclination to the forward ZA, which is the daily operation of the pelvis.

  (6) The drive unit 50 changes the right sciatic support portion 23 and the left sciatic support portion 33 in the order of the reference state, the right high state, the right rear high state, the reference state, the left high state, the left rear high state, and the reference state. To do. For this reason, it is possible to make the user perform an exercise that reproduces the motion of the pelvis during walking.

  (7) In the pelvic exercise device 1, when one of the right sciatic support 23 and the left sciatic support 33 operates, the other of the right sciatic support 23 and the left sciatic support 33 does not operate. For this reason, when one of the right sciatic support 23 and the left sciatic support 33 operates, the pelvis on the side supported by the other of the right sciatic support 23 and the left sciatic support 33 becomes the axis of motion. For this reason, as compared with the configuration in which the right sciatic support 23 and the left sciatic support 33 operate at the same time, the pelvis is prevented from being displaced from the pelvic exercise device 1.

  (8) In the pelvic exercise device 1, the right sciatic support 23 and the left sciatic support 33 are operated by a common air pump 57. For this reason, the number of drive sources of the pelvis exercise device 1 can be reduced.

  (9) In the pelvic exercise device 1, the right sciatic support portion 23 and the left sciatic support portion 33 are constituted by airbags 23A, 23B, 33A, 33B. For this reason, the operation amount of the right sciatic support portion 23 and the left sciatic support portion 33 is limited by the upper limit of the expansion amount of the airbags 23A, 23B, 33A, 33B. For this reason, the operation amount of the right sciatic support portion 23 and the left sciatic support portion 33 can be kept within a previously assumed range. That is, the right sciatic support 23 and the left sciatic support 33 are prevented from applying an unexpected load to the user.

  (10) In the pelvis exercise device 1, the integrated drive unit 40 is configured by air bags 42 and 43. For this reason, the operation amount of the integrated drive unit 40, that is, the rotation amount of the turntable 41 is limited by the upper limit of the expansion amount of the airbags 42 and 43. For this reason, it is possible to keep the rotation amount of the turntable 41 within a presumed range. That is, the turntable 41 is prevented from applying an unexpected load to the user.

  Moreover, since the integral drive part 40 is comprised by the airbags 42 and 43, the rotation amount of the turntable 41 can be changed by changing the supply and discharge time of the air to the airbags 42 and 43. . For this reason, it becomes easy to respond to various requests for the amount of rotation of the turntable 41.

  (11) The pelvic exercise device 1 has the right lumbar support portion 22 and the left lumbar support portion 32. For this reason, the user can easily take an appropriate posture by aligning the right lumbar vertebra support part 22 and the left lumbar vertebra support part 32 with the lumbar vertebra.

  (12) The pelvic exercise device 1 includes a right pelvis support portion 21 and a left pelvis support portion 31. For this reason, it can suppress that the training effect by the pelvis exercise | movement apparatus 1 falls because a user's user's buttocks and pelvis shift | deviate with respect to the sciatic support parts 23 and 33.

  The right rod end 151 connects the right sciatic support 123 and the main body 10 in a swingable manner. The left rod end 152 connects the left sciatic support 133 and the main body 10 so as to be swingable.

Operation | movement of the pelvis exercise | movement apparatus 1 is demonstrated.
As shown in FIG. 13, the right sciatic support 123 and the left sciatic support 133 have a width direction X, a depth direction Z, a height direction Y, and an inclination direction around the rotation axes PR and PL of the sciatic supports 123 and 133. S and the rotation direction R around the rotation center C of the turntable 41 are moved. Hereinafter, in the inclination direction S, the direction in which the front ZA moves to the upper YA is referred to as a first inclination direction SA, and the direction in which the front ZA moves to the lower YB is referred to as a second inclination direction SB.

  As shown in FIG. 12, the right sciatic support 123 is rotatably attached to the turntable 41. As shown in FIG. 13A, the rotation axis PR of the right sciatic support 123 with respect to the turntable 41 has a right end of the right sciatic support 123 when the longitudinal direction of the right sciatic support 123 is parallel to the depth direction Z. It is formed from the part toward the left end part. The rotation axis PR goes from the rear ZB to the front ZA as it goes from the right end to the left end. That is, the rotation axis PR is parallel to the upper surface of the right sciatic support 123 and is inclined with respect to the short direction of the right sciatic support 123.

  As shown in FIG. 12, the right sciatic support 123 is rotatably attached to the turntable 41. As shown in FIG. 13A, the rotation axis PL of the left sciatic support 133 with respect to the turntable 41 has a left end of the left sciatic support 133 when the longitudinal direction of the left sciatic support 133 is parallel to the depth direction Z. It forms from the part toward the right end part. The rotation axis PL goes from the rear ZB to the front ZA as it goes from the left end to the right end. In other words, the rotation axis PL is parallel to the upper surface of the left sciatic support 133 and is inclined with respect to the short direction of the left sciatic support 133.

  The right sciatic support 123 rotates around the rotation axis PR. For this reason, the longitudinal direction of the right sciatic support 123 is inclined with respect to the horizontal plane. As shown in FIG. 13B, the left ischial support 133 rotates around the rotation axis PL. For this reason, the longitudinal direction of the left ischial support portion 133 is inclined with respect to the horizontal plane.

  As shown in FIGS. 12 and 13, when the motor 153 rotates in one direction, the rotation of the motor 153 is transmitted to the turntable 41 via the worm 144 and the helical gear 143. The turntable 41 rotates in the first rotation direction RA by the rotation of the helical gear 143.

  When the turntable 41 rotates in the first rotation direction RA, the right sciatic support portion 123 is swung with the right rod end 151 so that the front end portion, right end portion, rear end portion, and left end portion of the right sciatic support portion 123 are The operation of sequentially inclining from the lower YB to the upper YA is repeated.

  When the turntable 41 rotates in the first rotation direction RA, the left sciatic support 133 is moved by the left rod end 152 so that the rear end, left end, front end, and right end of the left sciatic support 133 are The operation of sequentially inclining from the lower YB to the upper YA is repeated.

  That is, when the turntable 41 rotates in the first rotation direction RA, the right sciatic support 123 and the left sciatic support 133 operate symmetrically on the turntable 41.

  When the motor 153 rotates in the other direction, the rotation of the motor 153 is transmitted to the turntable 41 via the worm 144 and the helical gear 143. The turntable 41 rotates in the second rotation direction RB by the rotation of the helical gear 143.

  When the turntable 41 rotates in the second rotation direction RB, the right sciatic support 123 is moved by the right rod end 151 so that the rear end, left end, front end, and right end of the right sciatic support 123 are The operation of sequentially inclining from the lower YB to the upper YA is repeated.

  When the turntable 41 rotates in the second rotational direction RB, the left sciatic support portion 133 is swung with the left rod end 152 so that the front end portion, right end portion, rear end portion, and left end portion of the left sciatic support portion 133 are The operation of sequentially inclining from the lower YB to the upper YA is repeated.

  That is, when the turntable 41 rotates in the second rotation direction RB, the right sciatic support 123 and the left sciatic support 133 operate symmetrically on the turntable 41.

  Further, when the turntable 41 rotates in the second rotation direction RB, the right sciatic support 123 and the left sciatic support 133 operate in the opposite direction to when the turntable 41 rotates in the first rotation direction RA.

  Thus, when the motor 153 (see FIG. 12) is driven, the right sciatic support 123 and the left sciatic support 133 move in the width direction X, the depth direction Z, the height direction Y, the tilt direction S, and the rotation direction R. Movement occurs synchronously.

  With reference to FIG. 14, an example of the operation | movement aspect of the pelvis exercise | movement apparatus 1 is demonstrated. In addition, the broken line in a figure shows operation | movement of the right sciatic support part 123, and the continuous line has shown operation | movement of the left sciatic support part 133. FIG.

  In the following, a period until the turntable 41 moves from the reference phase to the maximum in the first rotation direction RA by the rotation of the motor 153, moves to the maximum in the second rotation direction RB through the reference position, and returns to the reference position. Is a unit period TX. The reference position corresponds to a state in which the rotation phase of the turntable 41 is the reference phase and the right sciatic support 123 and the left sciatic support 133 are parallel to the floor surface F.

  As shown in FIG. 14A, in the unit period TX, the right sciatic support 123 moves to the maximum in the first tilt direction SA from the reference phase around the rotation axis PR, passes through the reference position, It moves to the maximum in the tilt direction SB and returns to the reference position.

The part 133 is horizontally moved in the longitudinal direction. The right drive part of this modification is comprised by the gear attached to the lower surface of the right sciatic support part 123, and the rail attached to the turntable 41, for example. The left drive unit of this modification is configured by a gear attached to the lower surface of the left sciatic support 133 and a rail attached to the turntable 41. The gears of the right sciatic support 123 and the left sciatic support 133 of this modification rotate in opposite directions. For this reason, the right sciatic support 123 and the left sciatic support 133 move in directions opposite to each other in the longitudinal direction. The longitudinal direction of the right sciatic support 123 and the longitudinal direction of the left sciatic support 133 may be at an angle or in parallel with each other.

  (C) In the pelvic exercise device 1 shown in FIG. 19, the right drive unit horizontally moves the right sciatic support 123 in the width direction X, and the left drive unit horizontally moves the left sciatic support 133 in the width direction X. The right drive part of this modification is comprised by the gear attached to the lower surface of the right sciatic support part 123, and the rail attached to the turntable 41, for example. The left drive unit of this modification is configured by a gear attached to the lower surface of the left sciatic support 133 and a rail attached to the turntable 41. The gears of the right sciatic support 123 and the left sciatic support 133 of this modification rotate in different directions. For this reason, the right sciatic support 123 and the left sciatic support 133 move in different directions in the width direction X. The longitudinal direction of the right sciatic support 123 and the longitudinal direction of the left sciatic support 133 may be at an angle or in parallel with each other. Further, the right drive unit horizontally moves the right sciatic support 123 in a direction inclined with respect to the width direction X, and the left drive unit horizontally moves the left sciatic support 133 in a direction inclined with respect to the width direction X. You can also.

  (D) In the pelvic exercise device 1 shown in FIG. 20, the right drive unit moves the right sciatic support 123 in the shape of 8 in a side view, and the left drive unit has 8 in the left sciatic support 133 in a side view. Move in a letter shape. The right drive unit of this modification has a worm gear that moves the right sciatic support 123 upward YA and lower YB in addition to the horizontal movement mechanism in the longitudinal direction of the modification (C). The left drive unit of this modification has a worm gear that moves the right sciatic support 123 upward and downward YB in addition to the horizontal movement mechanism in the longitudinal direction of the modification (C).

In the pelvic exercise device 1 of this modified example, the right sciatic support 123 and the left sciatic support 133 operate in an 8-character shape in a side view, as shown in FIGS. 20 (a) to 20 (d).
Specifically, first, as shown in FIG. 20A, the right sciatic support 123 moves to the lower YB and the left sciatic support 133 moves to the upper YA. Next, as shown in FIG. 20B, the right sciatic support 123 moves forward ZA and upward YA, and the left sciatic support 133 moves backward ZB and downward YB.

Thereafter, the right sciatic support part 123 and the left sciatic support part 133 move along an 8-shaped trajectory in a side view shown in FIG.

  In the pelvic exercise device 1 of this modification, the right sciatic support 123 and the left sciatic support 133 include an eight-letter operation. For this reason, the circumference of the waist is easier to move with the movement of the right sciatic support 123 and the left sciatic support 133 than the movement in one direction. For this reason, a user's waist circumference is moved well. For this reason, a user's waist circumference can be stimulated effectively. In addition, the waist of the user is trained.

  In the pelvic exercise device 1 of the second embodiment, the right sciatic support 123, the left sciatic support 133, and the integrated drive unit 140 are operated by one motor 153. However, the configuration of the pelvic exercise device 1 is not limited to this. For example, the pelvic exercise device 1 according to the modified example includes a plurality of motors, and the right sciatic support 123, the left sciatic support 133, and the integrated driving unit 140 are operated by different motors. In the pelvic exercise device 1 of this modification, the motor of the right sciatic support 123 can be arranged on the turntable 41, and the motor and the right sciatic support 123 can be connected by a rod end. Further, the motor of the left sciatic support portion 133 can be arranged on the turntable 41, and the motor and the left sciatic support portion 133 can be connected by a rod end. Moreover, the pelvic exercise device 1 of this modification can also operate the right sciatic support 123 and the left sciatic support 133 asymmetrically. Moreover, the pelvis exercise | movement apparatus 1 of this modification can also operate the right sciatic support part 123 and the left sciatic support part 133 alternately. Moreover, the pelvic exercise device 1 of this modification can also operate only one of the right sciatic support 123 and the left sciatic support 133 and keep the other stationary.

  In the pelvic exercise device 1 of the second embodiment, the motor 153 is used as the drive source, but an air bag, a solenoid, or the like can also be used as the drive source. In this case, the linear motion of the drive source rotates the turntable 41.

  In the pelvic exercise device 1 of the second embodiment, the sciatic support parts 123 and 133 are swingably attached to the turntable 41 by rod ends 151 and 152. However, the configuration of the pelvic exercise device 1 is not limited to this. In short, any configuration can be adopted as long as the sciatic support portions 123 and 133 are swingably attached to the turntable 41. For example, a profile protrusion is formed on one of the lower YB side surface of the sciatic support portions 123 and 133 and the upper YA side surface of the turntable 41, and the lower YB side surface and the turntable 41 of the sciatic support portions 123 and 133. A guide having an inclined surface is formed on the other of the upper YA side surfaces. The profile protrusion moves relatively along the inclined surface of the guide. For this reason, the sciatic support parts 123 and 133 swing with respect to the turntable 41.

  The driving unit 150 of the second embodiment is driven by the right rod end 151 and the left rod end 152. However, the configuration of the drive unit 150 is not limited to this. For example, the drive unit 150 of the modification shown in FIG. 21 is driven by the right airbag 154 and the left airbag 155. As shown in FIG. 21 (a), the right sciatic support 123 is disposed above the right airbag 154. The left ischial support part 133 is disposed above the left airbag 155.

  The right sciatic support 123 is attached to the turntable 41 via a rotation shaft 156 at the left XB of the right sciatic support 123. For this reason, as shown in FIG. 21B, when the right airbag 154 is inflated, the right sciatic support 123 is tilted about the rotation shaft 156, and the right end moves upward YA relative to the left end. To do.

  The left sciatic support 133 is attached to the turntable 41 via a rotation shaft 156 at the right side XA of the left sciatic support 133. For this reason, when the left airbag 155 is inflated, the left sciatic support 133 is tilted about the rotation shaft 156, and the left end moves to the upper side YA than the right end.

  -The pelvis exercise | movement apparatus 1 of the modification shown by FIG. 21 can also be changed as shown in FIG. That is, as shown in FIG. 22A, in the pelvic exercise device 1 of the modified example, the right sciatic support 123 is attached to the turntable 41 via the rotation shaft 156 in the front ZA of the right sciatic support 123. It has been. For this reason, as shown in FIG. 22B, when the right airbag 154 is inflated, the right sciatic support portion 123 is tilted around the rotation shaft 156, and the rear end portion is located above the front end portion YA. Moving.

  The left sciatic support 133 is attached to the turntable 41 via a rotation shaft 156 in the front ZA of the left sciatic support 133. For this reason, when the left airbag 155 is inflated, the left ischial support portion 133 is inclined about the rotation shaft 156, and the rear end portion moves to the upper side YA relative to the front end portion.

  In the pelvic exercise device 1 of each embodiment, the protrusion on the upper YA side surface of the main body 10 is inserted into the slide groove on the lower YB side surface of the turntable 41. However, the configuration of the pelvic exercise device 1 is not limited to this. For example, in the integrated driving unit 400 of the modification shown in FIG. 23, the upper plate 411 of the turntable 410 rotates. The turntable 410 includes an upper plate 411, an intermediate plate 412, a lower plate 413, a shaft portion 414, and needle rollers 415. The shaft portion 414 is inserted into a through hole formed in the center of the upper plate 411, the middle plate 412, and the lower plate 413. The needle rollers 415 are arranged in through grooves 412 </ b> A that are radially formed in the intermediate plate 412. The diameter of the needle roller 415 is made larger than the thickness of the middle plate 412. For this reason, the needle roller 415 functions as a bearing that smoothly rotates the upper plate 411 and the lower plate 413. The connection part 45 is connected to the outer periphery of the upper plate 411. For this reason, when the connecting portion 45 moves to the right XA and the left XB, the upper plate 411 rotates on the needle rollers 415.

  In the modification shown in FIG. 23, the connecting portion 45 can be arranged at any position on the outer periphery of the upper plate 411. For this reason, it can change suitably in consideration of the external appearance design, usability, etc. of the pelvis exercise device 1.

  -The following structures can also be added to the pelvis exercise apparatus 1 of each said embodiment. That is, the pelvis exercise device 1 of the modified example shown in FIG. The thigh support portion 160 is located on the upper YA side of the main body 10 and on the front side ZA than the turntable 41. The thigh support part 160 includes a base part 161 and a swing part 162. The base 161 is fixed to the main body 10. The swinging portion 162 has a spherical shape at the end on the lower YB side. The swinging portion 162 has a spherical end attached to the upper YA side surface of the base portion 161. For this reason, the rocking part 162 can incline the surface on the upper YA side of the rocking part 162 with the spherical tip as a base point with respect to the base part 161. The upper YA side surface of the swinging part 162 supports the thigh.

  When the pelvis is moved by the operations of the right sciatic support portions 23 and 123, the left sciatic support portions 33 and 133, and the integrated drive portions 40 and 140, the thigh also moves. At this time, if the foot is installed on the floor surface F, the friction between the foot and the floor surface F suppresses the movement of the thigh. For this reason, there exists a possibility that the operation | movement of a pelvis may be suppressed.
