Description

  The present invention relates to a spinal correction device for correcting a user's spine.

  For example, when correcting a spine with a chiropractor, the vertebra is corrected by giving a displacement that adjusts the position by a technique. There is also a method of obtaining a spinal correction effect by giving a stimulus for activating the contraction force to a spine standing muscle group supporting the vertebrae constituting the spine by a technique. For example, when the transverse spinous muscles of the spine upright muscle group have been extended due to the strain of the spine, give a motion that repeatedly pulls them to the extended state, It promotes the activation of contractile force. According to the transverse spinous muscle with activated contraction force, the spine can be self-resolved and the spine can be corrected.

  By the way, the development of a spinal correction device that obtains the self-correcting effect of the spine by activating the contraction force of the spine standing muscle group as described above is expected even without a specialist such as a chiropractor.

  In order to activate the contraction force of a specific spine standing muscle group and obtain the self-correction effect of the spine by using the device, as in the case of a procedure by a specialist such as a chiropractor, a specific region is repeatedly exercised correctly. There must be. That is, it is necessary to strictly adjust the relative positional relationship between the user and the spinal correction device. The structure of the positioning mechanism device for such adjustment is complicated, and the device tends to be large.

  The present invention has been made in view of the above-described situation, and the object of the present invention is to be able to be assembled in a small and simple manner, and by dynamically applying force to the human body as described below, It is an object of the present invention to provide a spinal correction device that can easily correct the spine.

  A spinal correction device according to the present invention is a spinal correction device that corrects a user's spine, and swings the waist by applying motion to a symmetrical position across the user's spine with the trunk upright facing forward. A lower limb motion part to be moved, a pair of grip parts provided in front of the lower limb motion part and gripped by both hands of the user, and the front of the lower limb motion part in a state of driving the lower limb motion part And a control unit that moves the grip portion relative to the lower limb motion portion between the position of the limb and the side position.

  According to the apparatus of the present invention, by twisting the spine, the transverse spinous muscles of the erected spine muscle group are stretched according to the strain of the spine. Then, the position of the lumbar part is stabilized by giving a motion to a symmetrical position across the user's spine, thereby stabilizing the position of the lumbar part, and transmitting a trembling vibration between vertebrae in the spine. In particular, the tremor is absorbed in the part where the spine is distorted, and the transverse spinous muscle related to the part can be repeatedly displaced from the extended state to the extended state. That is, it is possible to easily correct a vertebra having a distortion without strictly adjusting the relative positional relationship between the user and the spinal correction device. According to this invention, since a mechanism for positioning the user to the spinal correction device is not required, the device can be assembled in a small and simple manner.

  In the above invention, the lower limb motion unit may swing the waist through both limbs while the user is standing. From the lower limbs, movement is given to the symmetrical position of the pelvis across the spine. The lower limb movement part can move the user's waist by swinging the left and right symmetrical positions of the pelvis with the spine in between, stabilizing the position of the waist and transmitting tremors between the vertebrae.

  In the above invention, the lower limb motion section may include a footboard that moves the left and right legs of the user up and down in opposite phases. The vertical movement of the opposite phase is given to the left and right of the lower limbs, and the connection position between the spine and the pelvis is almost the center of the swing of the pelvis, so that trembling can be transmitted between the vertebrae.

  In the above invention, the lower limb motion part is a tread that swings around an axis so as to tilt the back surface of the lower limb of the user forward and backward, and the axis is disposed directly below the spine of the user. It is good also as a feature. An axis extending in the left and right direction of the user so that the foot sole of the user's lower limb is tilted forward and backward is placed directly under the spine, so that the upper and lower sides of the pelvis are symmetrically positioned above and below the spine. Exercise is given. Along with the movement when the user tries to balance the standing position, a trembling vibration can be transmitted between the vertebrae.

  In the above invention, the pair of grips may be provided at both ends of a single bar arranged horizontally. The user can select as appropriate whether to hold the grip portion in the prolapsed position or the pronation position. In particular, when the grasping portion is held in the prorotated position, the side of the upper limb is tightened more than in the case where the grasped portion is held in the pronation position, so that the position of the trunk is stabilized. As a result, the tremor is sufficiently absorbed in the distorted portion of the spine, and the transverse spinous muscle related to the part can be repeatedly displaced from the extended state to the extended state.

  In the above invention, the rod-like body may swing around the rotation axis in the vicinity of the central portion in the longitudinal direction while maintaining the level. By introducing vibrations from both upper limbs to the shoulders that sandwich the spine, the central axis of spine twist along the length of the spine can be determined, and the posture of the user can be stabilized.

  First, the principle for obtaining the spinal correction effect according to the present invention will be described.

  As shown in FIG. 1, the transverse spinous muscles 5 of the erected spine muscle group (not shown) for supporting the vertebrae 2 constituting the spine 1 are the lateral processes 4 on the side of the vertebrae 2 and the vertebrae 2 above the lateral processes 4. It is the muscle which connects the spinous process 3 of the back (back side). For example, when the spine is bent sideways, one of the left and right transverse spinous muscles 5 extends. If the person is healthy, the lateral bending of the spine 1 is eliminated by the contraction force of the transverse spinous muscles 5-2. However, when the contraction force of the transverse spinous muscle 5-2 is reduced, the lateral bending of the spine 1 cannot be eliminated. The spine 1 that cannot achieve complete elimination of lateral bending, that is, the spine 1 with chronic lateral bending, tilts toward the side bent.

  As shown in FIG. 2, when the spine 1 is twisted, the distance between the transverse process 4 ′ of the vertebra 2 ′ located below (the back side of the drawing) and the spinous process 3 of the vertebra 2 located above the spine 1 becomes long. Thus, the transverse spinous muscle 5-2 is stretched. Subsequently, along with the extension of the transverse spinous muscles 5-2, a motion that swings the waist is given to the human body with the upper body in an upright state. Then, the swing of the lumbar region is absorbed by causing the vertebrae 2 and 2 'to wiggle each other. That is, the repetitive motion between the stretched state and the stretched state is given to the transverse spinous muscle 5-2 by the motion of swinging the waist. As a result, the transverse spinous muscles 5-2 with reduced contraction force are activated, and after the twist of the spine 1 is released, the lateral flexion of the spine is resolved by the activated contraction force. The spine can be corrected.

  Next, a spinal correction device according to one embodiment of the present invention will be described in detail with reference to FIGS.

  As shown in FIG. 3, the spinal correction device 10 has an annular rotation covering the outer peripheral side of the cylindrical lower limb exercise unit 20 and the lower limb exercise unit 20 installed on the floor surface provided with the substantially square footboard 40. 30, a cylindrical rotating column 60 extending vertically upward from the rotating unit 30, a column 53 extending in the vicinity of the rotating column 60 and extending vertically upward from the rotating unit 30, and an operation unit disposed at the upper end of the column 53 52. The handle 50 is fitted into the fitting portion 61 at the upper part of the rotating column 60. Here, as shown in FIG. 3, an X axis, a Y axis, and a Z axis are defined.

The central housing 21 has a substantially rectangular opening 22 on the top surface thereof, and the tread plate 40 is provided so as to protrude from the inside to the outside of the central housing 21 so as to close the opening 22. . The footboard 40 is a substantially dish-shaped integrally formed member having a bent portion 40a along the periphery of a rectangular metal plate. Two rotating shaft attachment members 40b are provided on the back surface of the tread plate 40 so as to be separated from each other in a direction along the central axis M1 parallel to the Z axis. The rotating shaft mounting member 40b has a through hole 40b 'along the central axis M1. The central housing 21 is provided with two bearings 28 separated from each other in the direction along the central axis M1. The shaft 41 is inserted into the through-holes 40 b ′ of the two rotary shaft attachment members 40 b of the tread plate 40, and is rotatably supported by a recess 28 ′ provided in the upper part of the bearing 28. As a result, the footboard 40 can swing around the shaft 41 disposed along the central axis M1. On the surface of the tread board 40, tread portions 44a and 44b depicting the shape of the soles indicating the positions where the user's lower limbs should be placed are provided at symmetrical positions with the central axis M1 in between. Two connecting rod mounting members 40 ′ are mounted on the back surface of the tread plate 40, offset from the central axis M 1 by a predetermined distance in the −X direction.

  Referring to FIG. 6, a shaft 45 along the Z axis is rotatably supported on a stay 25 attached to the central housing 21, and a crank disk 26 is fixed to both ends thereof. One end of the connecting rod 42 is pivotally connected by a pin 27 to a position offset in the outer circumferential direction from the rotation axis of the crank disc 26, and the other end of the connecting rod 42 is connected to a connecting rod mounting member 40 ′ ( (See FIG. 5). The crank disk 26 is connected to a power transmission unit 23 including a gear, a pulley, and the like through a shaft 45, and the power transmission unit 23 is connected to a central drive unit 24 including a motor and the like. The central driving unit 24 can control the driving speed and the like by the central motor control unit 101.

  When the motor in the central drive unit 24 operates and rotates the crank disk 26 via the connected power transmission unit 23, the connecting rod 42 is connected to the connecting rod mounting member 40 with the shaft 41 having the central axis M1 as a fulcrum. Move 'up and down. As a result, the tread plate 40 performs a seesaw movement with the shaft 41 as the rotation axis. In the vicinity of the treads 44a and 44b of the tread board 40 described above, the stroke for moving the back of both feet of the user up and down is preferably 3 cm or less, which is an amount that is not excessive to cause tremors in the spine. More preferably.

  As shown in FIG. 4, a heel portion 71 protruding to the outer peripheral side is provided on the outer periphery of the bottom of the lower limb exercise unit 20. The upper surface of the flange 71 is polished smoothly and contacts the roller 72. At least three or more roller groups 72 are arranged on the inner side of the lower end of the rotation unit 30 so that the rotation unit 30 can rotate with respect to the lower limb motion unit 20.

  Referring to FIG. 7, a rotation drive unit 31 including a gear, a motor, and the like that can be controlled by a rotation motor control unit 102 is fixed in a rotation housing 33 that partitions the rotation unit 30. Established. The rotation drive unit 31 is connected to a worm gear 32 having a rotation axis L2 orthogonal to the rotation axis of the rotation unit 30. The worm gear 32 is meshed with a rack gear 29 provided over approximately a half of the outer periphery of the central casing 21 through a window 34 provided on the inner peripheral side of the rotating casing 33. When the worm gear 32 is rotated by the rotation drive unit 31, the rotation unit 30 can rotate the outer periphery of the lower limb motion unit 20 up to about 90 degrees to the left and right with respect to the reference point A (see FIG. 3).

  Referring to FIGS. 3, 8 and 9, a through hole 37 is drilled in the top surface of the rotating housing 33 in the vicinity of the reference point A of the rotating portion 30. A hollow rotating column 60 is inserted into the through hole 37, and a lower end of the rotating column 60 is a rotating shaft parallel to the Y axis by bearings 36 a and 36 b provided on the bottom surface and the back surface of the top surface inside the rotating housing 33. It is supported so as to be rotatable about M2. Blade members 64 a and 64 b projecting in the −X direction are joined to the lower end portion of the rotation column 60 located inside the rotation housing 33. The blade members 64a and 64b are joined to the rotating column 60 so that opposing surfaces 64s that are spaced apart from each other and that face each other are parallel to the rotation axis M2. A cam 36 is provided between the blade members 64a and 64b so as to contact the blade members 64a and 64b. The cam 36 has a cam rotation axis M3 orthogonal to the rotation axis M2. The cam 36 is a disc eccentric with respect to the cam rotation axis M3, and is connected to a swing drive unit 35 including a gear, a motor, and the like. The swing drive unit 35 can control the drive speed and the like by the swing motor control unit 103.

  When the swing drive unit 35 is operated to rotate the cam 36, the blade members 64a and 64b reciprocate due to the rotation of the cam 36, and accordingly, the rotating column 60 repeats reciprocating motion around the rotation axis M2. . As a result, the handle 50 fitted to the upper portion of the rotating column 60 swings in the XZ plane about the rotation axis M2. The stroke of the back-and-forth movement in the vicinity of the gripping portions 51a and 51b of the handle 50 is preferably 8 cm or less.

  3 and 10, a fitting portion 61 having a substantially rectangular cross section is formed on the upper portion of the rotation column 60, and a plurality of height adjustment holes 61 ′ that are cut away from each other in the Y-axis direction. Is provided. A fitting hole 56 of the handle 50 is fitted into the fitting portion 61. Then, the handle 50 is fixed by allowing a through hole 50 ′ provided at the center of the handle 50 to communicate with one of the height adjusting holes 61 ′ and passing the pin 54 through the communication hole. With this configuration, the height of the handle 50 can be adjusted. It is preferable to provide the pin 54 with a mechanism for preventing the pin 54 from falling off. Grip portions 51a and 51b are provided at both ends of the handle 50, and rotation switches 55a and 55b are provided at the ends thereof. Further, a swinging switch 55c is provided inside the grip portion 51a. The rotation switches 55a and 55b and the swinging switch 55c are connected to the wirings 65a, 65b and 65c through wirings in a handle (not shown), respectively, and the wirings 65a, 65b and 65c pass through the inside of the hollow rotation column 60. To the central control unit 100 described later.

  Referring to FIG. 11, which is a control diagram of the spinal cord correction apparatus according to the present invention, the operation unit 52, the rotation switches 55a and 55b, and the swinging switch 55c are connected to the central control unit 100. A central motor control unit 101, a rotation motor control unit 102, and a swing motor control unit 103 are connected to the central control unit 100. By operating the operation unit 52, the rotation switches 55a and 55b, and the swinging switch 55c, an operation signal is sent from the central control unit 100 to each control unit, and the central drive unit 24 that causes the tread plate 40 to perform seesaw movement, the rotation unit The rotation drive unit 31 that rotates 30 and the swing drive unit 35 that swings the handle 50 can be controlled.

  Next, the usage method and operation | movement of the spine correction apparatus 10 are demonstrated in detail using FIG. 3 thru | or FIG.

  When there is a portion where the contractile force is reduced in the transverse spinous muscle 5, if the upper body is twisted by itself, the portion is unconsciously covered and the twist angle of the upper body becomes shallow. Therefore, the user twists his / her upper body to the left and right without moving his / her waist in a standing or sitting position, and confirms which of the left and right twist directions is shallower with respect to the twistable angle. Then, when the upper body is twisted by itself, the spinal correction device 10 is twisted toward the shallower twist angle, and the lumbar region is also swung to stretch the transverse spinous muscle 5 with reduced contraction force. is there.

  Referring to FIG. 3, first, the user stands up with the sole surface placed on the stepped portions 44 a and 44 b on which the shape of the sole is described, with the reference point A as the front. The handle 50 is held so that the user's forearm is substantially horizontal and the handle 50 is gripped in the inward or outward position so that the positional relationship with the user's shoulder does not change greatly when the handle 50 is moved. Adjust the height between the chest and the abdomen. Here, the pronation position refers to the orientation of the wrist joint relative to the elbow joint when the forearm is substantially horizontal and the thumb is inside and the palm is directed downward. The prorotated position refers to the orientation of the wrist joint relative to the elbow joint when the thumb is on the outside and the palm is directed upward. Further, the intermediate position refers to the orientation of the wrist joint with respect to the elbow joint when the thumb is on the top and the palm is on the side.

  Next, the operating portion 52 is operated to adjust the angular velocity at which the rotating portion 30 rotates. Since the angular velocity is also a rate of twisting the trunk and spine, it can be adjusted preferably in the range of 5 to 45 degrees / second so as not to cause unreasonable effects on the user's body.

Next, the frequency for the seesaw movement of the footboard 40 of the lower limb motion unit 20 is determined. Such a frequency may be arbitrarily determined within a frequency range required for vibrating the vertebrae constituting the spine in small increments, that is, within a range of 2 to 22 Hz. The user inputs the determined frequency value to the operation unit 52 and starts the lower limb motion unit 20 at a desired frequency. Specifically, referring to FIGS. 3, 4, and 11, by operating the operation unit 52, power is supplied from the central control unit 100 to the central drive unit 24 via the central motor control unit 101. . The rotational speed of a motor (not shown) can be changed by operating the operation unit 52 even after starting. The driving force obtained by the central drive unit 24 rotates the crank disk 26 via the power transmission unit 23. The rotation of the crank disk 26 is converted by the connecting rod 42 into a movement in which both ends of the tread plate 40 in the X-axis direction are moved up and down with the central axis M1 as a fulcrum. That is, the tread plate 40 performs a seesaw movement with the central axis M1 as a fulcrum. Since the step portions 44a and 44b are provided symmetrically with respect to the central axis M1, they move in conjunction with each other in opposite phases.
By arranging the center axis M1 of the seesaw movement of the tread board 40 between the lower limbs of the user, the pedestals 44a and 44b are moved from the lower limbs to the left and right symmetrical positions of the pelvis with the spine interposed therebetween. Phase up and down motion is given. By giving up-and-down motions in opposite phases to the left and right of the lower limbs, the connection position between the spine and the pelvis is almost the center of the pelvic swing, so that the tremors can be transmitted little by little to the vertebrae. In addition, the user in the standing position can maintain the posture with the waist portion facing the reference point A in order to balance the introduction of the seesaw movement of the footboard 40. The frequency of seesaw movement of the footboard 40 is preferably 2 to 22 Hz.

  The use method and operation of the spinal correction device 10 will be described with reference to FIGS. 7, 10, and 11. The user grips the grips 51a and 51b of the handle 50 in the prone position.

The user turns the turning unit 30 by operating the turning switch 55a or 55b with the thumb. That is, when the user depresses the rotation switch 55a with the thumb of the right hand, power is supplied to the rotation drive unit 31 via the rotation motor control unit 102 by a signal from the central control unit 100. The rotation speed of the motor of the rotation drive unit 31 is controlled by the rotation motor control unit 102 so as to give the rotation unit 30 the angular velocity adjusted by the operation unit 52. When the turning switch 55a is pressed, the handle 50 is turned left so as to move to the left with respect to the reference point A, and when the turning switch 55a is released, the turning is stopped (or will be described later). Can be turned in the opposite direction by changing the setting so that.) By the same operation, the rotation unit 30 can be rotated rightward by operating the rotation switch 55b. Here, when the rotating unit 30 is rotated to a shallower one of the left and right twist angles, which has been confirmed in advance, the arm and shoulder of the user holding the gripping portions 51a and 51b are rotated. It is twisted by 30 rotations. That is, the shoulder is pivoted with respect to the spine 1. Therefore, the user who is maintaining the posture with the lower back facing the reference point A twists the upper spine 1 from the lower back.

  When the gripping portions 51a and 51b are gripped in the swirl position, the side portions of the upper limbs are tightened, so that the position of the trunk is stabilized. As a result, the tremor is sufficiently absorbed in the distorted portion of the spine, and the transverse spinous muscle related to the part can be repeatedly displaced from the extended state to the extended state. In addition, the user's side can be tightened and the movement of the handle 50 can be effectively transmitted to the shoulder, so that “play of movement” of the user's arm and shoulder is reduced, and eventually the spine 1 itself is also twisted. . The user stops the rotation of the rotating unit 30 before feeling pain around the arm, shoulder and spine 1. As described above, the user's lower back is not twisted with respect to the lower limbs, and the spine 1 is twisted between the lower back and the shoulder.

  As the spine 1 is twisted, the transverse spinous muscles (see FIG. 1) of the erected spine muscles are stretched in accordance with the strain of the spine. Then, the position of the lumbar part is stabilized by giving a motion to a symmetrical position across the user's spine, thereby stabilizing the position of the lumbar part, and transmitting a trembling vibration between vertebrae in the spine. In particular, the tremor is absorbed in the part where the spine is distorted, and the transverse spinous muscle related to the part can be repeatedly displaced from the extended state to the extended state. That is, it is possible to easily correct a vertebra having a distortion without strictly adjusting the relative positional relationship between the user and the spinal correction device. According to this invention, since a mechanism for positioning the user to the spinal correction device is not required, the device can be assembled in a small and simple manner.

  In the present embodiment, even if the rotating unit 30 tries to rotate beyond the limit of twisting of the user's body, for example, in the case of rotating in the left direction, the user's right hand is the rotation switch. Since it leaves | separates from 55a, rotation stops immediately.

  Next, other usage methods and operations of the spinal correction device 10 will be described with reference to FIGS. 3 to 11 as appropriate. In this method of use, movement from the handle 50 is also given to the user.

  Referring to FIG. 3, the user adjusts the height of the handle 50 of the spinal correction device 10 and the angular velocity at which the rotating unit 30 rotates. Next, the frequency for the seesaw movement of the footboard 40 of the lower limb motion unit 20 is determined. Such a frequency is determined from a frequency necessary for oscillating the vertebrae constituting the spine in small increments, that is, an arbitrary frequency within a range of 2 to 22 Hz. After this determination, the user inputs this frequency value to the operation unit 52. Furthermore, the operating unit 52 is operated to determine the frequency at which the handle 50 swings within a range of 2 to 22 Hz, and the user inputs this frequency value to the operating unit 52.

  Next, the user operates the operation unit 52 to start the tread board 40 of the lower limb motion unit 20 at a desired frequency.

Subsequently, the user starts the handle 50 at a desired frequency, and grips the grip portions 51a and 51b of the handle 50 in the rotational position. Specifically, referring to FIGS. 9 to 11, the user presses the swing switch 55 c and power is supplied from the central control unit 100 to the swing drive unit 35 via the swing motor control unit 103. The swing drive unit 35 rotates the cam 36. The rotating cam 36 reciprocates the opposing surfaces 64s of the blade members 64a and 64b disposed at the lower end of the rotating column 60 in the Z-axis direction. Accordingly, the rotating column 60 in FIG. 9 rotates by a predetermined angle alternately clockwise and counterclockwise with the rotation axis M2 as a fulcrum, and the handle 50 fitted to the upper portion of the rotating column 60 is In the horizontal plane (XZ plane), the rotary shaft M2 can be repeatedly swung around the fulcrum.

  Further, similarly to the above, the user operates the rotation switch 55a or 55b to rotate the rotation unit 30 in a desired direction with respect to the lower limb motion unit 20, thereby to twist the spine 1.

  By swinging the handle 50, the user's upper limb has already been given a movement to move its left and right in opposite phases. By this swinging, the left and right of the user's shoulder are swung back and forth in opposite phases before the spine 1 is twisted with the rotation of the rotating unit 30, and along the length direction of the spine. The central axis of the spinal twist can be determined, and the posture of the user can be stabilized. In order to obtain this stable posture, the swing frequency of the handle 50 is preferably 2 to 22 Hz.

  In the above-described operation, if the frequencies of the seesaw movement of the footboard 40 and the swing of the handle 50 are matched, the axis of the twist center of the spine 1 is easily determined. In particular, when the frequency of the seesaw movement of the tread plate 40 and the swing of the handle 50 are matched, when the phase is adjusted so that the gripper 51b is closest to the user when the tread 44b is raised highest, The positional relationship between the lumbar part and the shoulder part substantially coincides with the positional relation between the lumbar part and the shoulder part during walking, and the axis of the twist center of the spine 1 can be easily determined.

  It should be noted that the rotation switches 55a and 55b may be provided on the inner side of the gripping portion so as to be operable even when the gripping portions 51a and 51b are gripped in the pronation position.

  Further, in this embodiment, the lower limb exercise unit 20 is fixed to the floor surface, and the rotation unit 30 is rotated around the lower limb exercise unit 20, but conversely, the rotation unit 30 is placed on the floor surface. It is good also as a structure which fixes and rotates the lower limbs movement part 20. FIG.

  When the user presses the rotation switch 55a or 55b to rotate the rotation unit 30, the user may release the hand from the switch so that the rotation unit 30 is immediately reversed. With such control, particularly in the vicinity of the limit of the twist of the user's body, the strain on the spine 1 can be corrected while reducing the burden on the user.

  Although not shown, the shaft 41 may be provided in parallel with the X axis so that both ends of the tread plate 40 in the Z axis direction can be moved up and down in opposite phases. In other words, the axis extending in the left and right direction of the user is placed directly under the spine so that the foot sole of the user's lower limb is tilted forward and backward, so that they are opposite in phase to the front and back symmetrical positions of the pelvis across the spine. Is given up and down movement. On the other hand, the user swings back and forth in order to maintain balance so as to maintain a standing posture. Along with rocking when the user tries to balance the standing position, tremors can be transmitted little by little to the vertebrae. As a result, the transverse spinous muscle 5 (see FIG. 1) is repeatedly exercised in a stretched state and a further stretched state, and the reduced contractive force of the transverse spinous muscle 5 is activated, and the recovered contractive force causes The distortion of the spine 1 can be corrected.

The oscillating body 96 is connected so as to oscillate about the central axis M1.
In addition, the center drive part 24, the power transmission part 23, the shaft 45, the crank disc 26, and the connecting rod 42 are the same members as the aspect with which the foot board 40 was mounted | worn.
As shown in FIG. 14, the swinging body 96 is provided with a slit along the XY plane at the center of both ends. The slit is provided from the end toward the central axis M1 up to about one third of the distance between the end and the central axis M1. A through hole 97b that penetrates the slit in the Z-axis direction and extends in the longitudinal direction (X-axis direction) of the swinging body 96 is provided in the side wall portion on one end side of the swinging body 96 across the slit. Further, the rocking body 96 has a rotating shaft attaching portion 98 having a through hole at a substantially central portion thereof, and the shaft 41 is inserted through the through hole in the Z-axis direction. Since both ends of the shaft 41 are pivotally supported by the two bearings 28, the swinging body 96 can swing around the central axis M1.
On the other hand, the upper end of the slide shaft 92b extending in the vertical direction is fixed to the lower surface of the tread plate 91b. The slide shaft 92b is inserted through a cylindrical member 94b that passes through an upper lid 93 that closes the upper portion of the central housing 21. An insertion hole is provided in the Z-axis direction at the lower end of the slide shaft 92b.
The insertion hole at the lower end of the slide shaft 92b and the slide through hole 97b of the swing body 96 described above are arranged so that the swing motion of the swing body 96 about the central axis M1 can be converted into the vertical movement of the slide shaft 92b. A pin 95b communicating in the Z-axis direction is inserted.
Similarly, the slide shaft 92a also has a pin 95a inserted into the through hole at the lower end thereof and is connected to the other end of the swing body 96. The swing motion of the swing body 96 with the central axis M1 as a fulcrum is the slide shaft 92a. It is converted into vertical movement.

The footboards 91a and 91b reciprocate in opposite directions in the vertical direction. A user who places the backs of both feet on the footboards 91a and 91b is moved up and down through the left and right lower limbs to the left and right symmetrical positions of the pelvis with the spine interposed therebetween. Further, the predetermined stroke can be accurately given without depending on the distance between the right foot and the left foot. Such a stroke is preferably 2 cm or less.
The footboards 91a and 91b may be configured to move up and down separately by a cam mechanism (not shown). For example, the tread plate 91b may be moved up and down while the tread plate 91a is stationary, then the tread plate 91b may be stopped, and the tread plate 91a may be moved up and down during that time.
It is preferable that the foot plate 40 or the foot plates 91a and 91b are provided with foot fixing means using a surface fastener, rubber, or the like that presses the back of the user's foot and presses the back of the foot against the foot plate.

  Furthermore, instead of the handle 50 shown in FIG. 3, a handle 80 as shown in FIG. 12 may be used. The handle 80 has a substantially rectangular fitting hole 86 in the center. A fitting portion 61 (see FIG. 10) at the top of the rotating column 60 is fitted into the fitting hole 86. At both ends of the handle 80, slits 80a and 80b are horizontally cut, and slide holes 89a and 89b facing vertically are provided. One ends of gripping bodies 82a and 82b are inserted into the slits 80a and 80b. On the other hand, pins 84a and 84b implanted at one end of the slide holes 89a and 89b are slidably engaged. The L-shaped gripping bodies 82a and 82b are bent in a direction parallel to the X axis and away from each other, and slide parts 83a and 83b extending in the −Z axis direction from the one end portion where the pins 84a and 84b are implanted. Gripping portions 81a and 81b. The slide parts 83a and 83b are slidably inserted into the cylindrical members 85a and 85b. In a state where the rotating column 60 is closest to the reference point A, the cylindrical members 85a and 85b are fixed to the upper ends of the upper fixing columns 87a and 87b so that the longitudinal direction thereof is parallel to the Z axis. The upper fixed columns 87a and 87b are attached to the hollow lower fixed columns 87c and 87d vertically provided on the rotating portion 30 so as to be slidable in the vertical direction.

  The upper fixed columns 87a and 87b can be adjusted in height with respect to the lower fixed columns 87c and 87d by height adjusting pins 88a and 88b and height adjusting holes 90a and 90b. One end can be inserted into the slits 80 a and 80 b of the handle 80.

  With such a configuration, a linear motion in the front-rear direction can be given to the left and right upper limbs of the user holding the gripping portions 81a and 81b in the left-right reverse phase. Even when such a handle 80 is used, the axis of the twist center of the spine 1 can be determined in the same manner as the handle 50 described above.
