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. In addition, there is a method of obtaining a spinal correction effect by applying 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 circumstances, and an object of the present invention is to provide a spinal correction device that can be assembled in a small size and can be easily corrected. It is.

  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 a motion to a symmetrical position across the user's spine with the trunk standing upright. 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 where the lower limb motion part is driven A control unit that moves and fixes the grip portion relative to the lower limb motion unit from a position toward a 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 at the part where the spine is distorted, that is, at the discontinuity point, 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 a symmetrical position across the pelvic spine. The position of the lumbar region can be stabilized by applying a motion to a symmetrical position across the user's vertebra and swinging the lumbar region, so that the tremor can be transmitted to the vertebrae of the vertebrae little by little.

  In the above invention, the lower limb motion part is a step board that moves up and down alternately to vertically move the left and right of the user's lower limbs, and the central swing axis of the vertical movement is between the lower limbs of the user. It is good also as arrange | positioning so that it may come. By arranging the central swing axis of the vertical movement of the tread between the lower limbs of the user, vertical movements are alternately given from the lower limbs to symmetrical positions across the pelvic spine. The connection position between the spine and the pelvis is almost the center of the swing of the pelvis and can transmit tremors to the vertebrae of the spine.

  In the above invention, the pair of grips may be provided at both ends of a single bar arranged horizontally. The user can appropriately select whether the gripping part is held in the pronation position or the pronation position. Especially when the gripping part is held in the pronation position, the side part of the upper limb is held in the pronation position. The position of the tightened trunk is more stable than the case. As a result, the tremor is stably absorbed in the part where the spine is distorted, that is, the discontinuity, 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-shaped body may swing in a horizontal plane around a rotation axis in the vicinity of the central portion in the longitudinal direction. By introducing vibration from both upper limbs to both shoulders, that is, symmetrical positions across the spine, the central axis of the spine of the spine along the length direction of the spine can be stabilized, and the posture of the user can be stabilized.

It is a control diagram of the spinal correction device according to the present invention. It is a figure of the handle of the principal part of the spine correction apparatus by this invention.

  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, as shown in FIG. 1, when the spine is bent sideways, one of the left and right transverse spinous muscles 5 extends. If it is a healthy person, the lateral bending of the spine 1 is eliminated by the contraction force of the transverse spinous muscle 5-2. However, when the contractive force of the transverse spinous muscle 5-2 is reduced, the lateral bending of the spine 1 cannot be eliminated.

  Therefore, as shown in FIG. 2, when the spine 1 (see FIG. 1) is twisted, the transverse process 4 ′ of the vertebra 2 ′ located below (the back side of the drawing) and the spinous process of the vertebra 2 located above the transverse process 4 ′. 3 becomes longer, the transverse spinous muscle 5-2 is extended. 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 swinging the vertebrae 2 little by little. In other words, 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 muscle 5-2 having a reduced contraction force is activated, and after releasing the twist of the spine 1, 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 is a cylindrical lower limb exercise unit 20 installed on a floor provided with a substantially square footboard 40, and an annular rotation unit that covers the outer peripheral side of the lower limb exercise unit 20. 30, a cylindrical rotating column 60 extending vertically upward from the rotating unit 30, a handle 50 fitted to the fitting unit 61 on the upper part of the rotating column 60, and a column 53 extending vertically upward from the rotating unit 30, It includes an operation unit 52 erected in the vicinity of the rotating column 60 at the upper end of the column 53. Here, as shown in FIG. 3, an X axis, a Y axis, and a Z axis are defined.

The central driving unit 24 can control the driving speed and the like by the central motor control unit 101.
The crank member 26a having obtained the rotational motion is transmitted to the arm 92b joined to the power transmission joining member 93a via the arm 92a.
The pillar 91b fixed to the bottom surface 21a has a structure that is a fulcrum of an arm 92a that performs a seesaw motion, and the motion is joined to the footboards 40a and 40b by the arms 92c and 92d via the crank members 26b and 26c. It is configured to change to vertical movement via power transmission joining members 93b and 93c. The vertical movements of the footboards 40a and 40b are set to be alternately opposite movements.
The stroke to move the back of both feet up and down by the user depends on the distance between the backs of both feet, but the amount of footboards 40a and 40b is not too small and too small to cause tremors in the spine. As a result, it is preferably 1 cm or more, generally 3 cm or less, more preferably 2 cm or less.
7, the cylinder member 93 is fixed to the bottom surface 21a, the piston member 94 is fixed to the step platform 40, and the step platform 40 is stabilized. The inside of the cylinder member 93 is the lowest of the vertical movement of the step platform 40. The structure is such that 93a exists when the piston member inside the cylinder member abuts so that the piston member 94 does not fall below the position.

  As shown in FIG. 4, a heel portion 71 projecting outward 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 rollers 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.

  Further, referring to FIG. 6, a rotation drive unit 31 including a gear, a motor, and the like that can control a drive speed and the like by the rotation motor control unit 102 is provided in the rotation housing 33 that partitions the rotation unit 30. It is fixed. 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.

  When the cam 36 is rotated by the swing driving unit 35, the rotating column 60 is rotated by the blade members 64a and 64b repeatedly reciprocating 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 around the rotation axis M2. Regarding the swinging of the handle 50, the back-and-forth movement stroke in the vicinity of the gripping portions 51a and 51b is preferably 20 cm or less, but more preferably 8 cm or less in consideration of the safety of the user.

  Referring to FIGS. 3 and 9, a fitting portion 61 having a substantially rectangular cross section is formed on the upper portion of the rotating column 60, and a plurality of height adjusting holes 61 ′ that are cut away from each other in the Y-axis direction. Is provided. A handle 50 is fitted into the fitting portion 61 through a fitting hole 56, and a through hole 50 ′ provided at the center of the handle 50 is connected to one of the height adjusting holes 61 ′ by a pin 54. Fix it. With this configuration, the height of the handle 50 can be adjusted. The pin 54 is preferably provided with a drop-off prevention mechanism. 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 wirings 65a, 65b and 65c via wirings in a handle (not shown), and the wirings 65a, 65b and 65c pass through the inside of the hollow rotation column 60 and will be described later. Connected to the central control unit.

  Referring to FIG. 10, the central control unit 100 is connected to each of the central motor control unit 101, the rotation motor control unit 102, and the swing motor control unit 103. The central control unit 100 is connected to the operation unit 52. By operating the operation unit 52, the rotation switches 55a and 55b, and the swinging switch 55c, the central control unit 100 sends control signals to the respective control units. Is done.

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

  Users should twist their body from side to side in a standing position (do not move their waists) or sitting, and check if the angle at which they can twist is shallow. If there is a portion where the contractile force is reduced in the transverse spinous muscle 5, if the body is twisted by itself, the portion is unconsciously covered and the twist angle becomes shallow. That is, when the body is twisted by itself, twisting is applied to the shallower twist angle by the device of the present invention, so that the transverse spinous muscle 5 with reduced contraction force can be extended.

  Referring to FIG. 3, the user first stands on the spine correction device 10 with the reference point A in front by placing the lower limbs on the step portions 44 a and 44 b on which the sole marks are described. 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.

  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 twisting the spine, it can be adjusted preferably in the range of 5 to 45 degrees / second so as not to cause unreasonableness in each part.

  Subsequently, referring to FIG. 9, the user holds the grip portions 51 a and 51 b of the handle 50 with the left and right hands, with the thumbs facing outward, that is, in the swivel position.

  Further, the user operates the rotation switch 55a or 55b with the thumb to rotate the rotation unit 30. Specifically, referring to FIGS. 6, 9, and 10, when the rotation switch 55 a is pressed with the right hand, power is supplied from the central control unit 100 to the rotation drive unit 31 via the rotation motor control unit 102. Supplied. The rotation speed of a motor (not shown) 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 leftward with respect to the reference point A. When the turning switch 55a is released, the turning is stopped and the handle 50 is fixed. Similarly, the rotation part 30 can be rotated rightward by the rotation switch 55b. Here, when the rotation unit 30 is rotated to one of the left and right with a shallow twistable angle, which has been confirmed in advance, the arm / shoulder of the user holding the gripping portions 51 a and 51 b is attached to the rotation portion 30. It is twisted with respect to the spine 1 by the rotation. At this time, the user should consciously make the waist face the reference point A and maintain the position of the waist so as not to twist. However, according to the frequency of the vertical movements of the footboards 40a and 40b described above, inertia It is difficult for the user's waist to change direction due to the force.

  When the gripping portions 51a and 51b are gripped in the swivel position, the side of the user can be tightened and the movement of the handle 50 can be stably transmitted to the shoulder portion. The “play of movement” of the user's arm / shoulder is reduced, and eventually the spine 1 itself is also twisted. The user stops the rotation of the rotation 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.

  In the above state, the user's transverse spinous muscle 5 (see FIG. 1) is in an extended state. The swing of the user's lumbar region is absorbed by the small tremors of each of the vertebrae 2 constituting the user's spine 1, and the tremor is absorbed particularly by the distorted portion of the spine that is a discontinuity point. Therefore, it is possible to repeatedly give motion to the transverse spinous muscles 5 that connect the vertebrae 2 to each other, particularly the transverse spinous muscles 5 related to the distortion of the spine. Repeated movement between the extended state of the transverse spinous muscle 5 and the extended state activates the reduced contractile force of the transverse spinous muscle 5. Thereby, after releasing the above-mentioned twist, the strain of the spine 1 can be corrected by the activated contractive force of the transverse spinous muscle 5.

  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. Immediately away from 55a, the rotation stops.

  Next, the usage method and operation | movement which rocks the handle | steering-wheel 50 in the above-mentioned spinal correction apparatus 10 are demonstrated.

  Referring to FIG. 3 and 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 in the same manner as described above. Further, the frequency at which the handle 50 swings is specified by operating the operation unit 52 within the same frequency range as described above, preferably in the range of 2 to 22 Hz.

  Next, the user operates the operation unit 52 to start the footboard 40 of the lower limb motion unit 20 at a desired frequency in the same manner as described above.

  Subsequently, the user starts the swinging of the handle 50 at a specified frequency, and holds the grips 51a and 51b of the handle 50 with the left and right thumbs facing outward, that is, in the swivel position. Specifically, referring to FIGS. 8 to 10, the user presses the swing switch 55 c, and power is supplied from the central control unit 100 to the swing drive unit 35 through the swing motor control unit 103. . The swing drive unit 35 rotates the cam 36. The rotation of the cam 36 is converted into left and right repetitive rotation around the rotation axis M2 of the rotating column 60 by the blade members 64a and 64b. Therefore, the handle 50 is repeatedly swung in the horizontal plane around the rotation axis M2.

  Further, as described 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, and torsion is applied to the spine 1.

  Here, the user's upper limb has already been given a motion to move back and forth alternately by swinging the handle 50. By such movement, before the spine 1 is twisted by the movement of the handle 50, the left and right sides of the user's shoulder are alternately swung back and forth, and the rotation axis for twisting the spine 1 is fixed. This stabilizes the twist center of the spine 1 provided by the handle 50. Therefore, the same effect of correcting the spine as when the handle 50 is not swung can be obtained more stably. In order to obtain such an effect, the cycle of the swing of the handle 50 is specified in the range of 2 to 22 Hz as described above.

  In the above-described operation, when the vertical movement of the footboard 40 and the swing of the handle 50 are synchronized, it becomes easier to stabilize the twist center of the spine 1 described above. In particular, when the left limb of the lower limb is raised to the highest level and the left limb of the upper limb is synchronized so as to descend most backward, the correspondence between the waist and shoulder close to walking is achieved, and the twist center of the spine 1 is most easily stabilized.

  It should be noted that the rotation switches 55a and 55b may be provided inside the gripper so that the thumbs 51a and 51b can be operated with the thumb facing inward, that is, 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 exercise | movement part 20. FIG.

  Further, instead of the handle 50, a handle 80 as shown in FIG. The handle 80 has a substantially rectangular fitting hole 86 in the center, and a fitting portion 61 (see FIG. 9) on the upper portion of the rotating column 60 is fitted thereto. At both ends of the handle 80, slits 80a and 80b are horizontally cut, and slide holes 89a and 89b are provided vertically opposite to each other. The implanted pins 84a and 84b are slidably engaged. The gripping bodies 82a and 82b are substantially L-shaped, and slide portions 83a and 83b extending from one end portion where the pins 84a and 84b are planted toward the front side, and outward at a substantially right angle at the front side end portion. Gripping portions 81a and 81b which are bent. The slide parts 83a and 83b are slidably inserted into cylinder members 85a and 85b described later. The cylindrical members 85a and 85b are vertically provided on the rotating portion 30 (see FIG. 3) so that the longitudinal direction thereof is parallel to the Z axis in a state where the rotating column 60 is closest to the reference point A. The fixing columns 87a and 87b are fixed to the upper ends of the lower fixing columns 87c and 87b.

  The upper fixing columns 87a and 87b are slidably fitted vertically into the hollow lower fixing columns 87c and 87d, and height adjustment pins 88a and 88b (other height adjustment pins not shown) and height adjustment holes 90a. And 90b (other height adjustment holes not shown) can be adjusted in height to fit the height (see FIG. 9) of the handle 80 adjusted by the height adjustment hole 61 ′ of the fitting portion 61. It is.

  With this configuration, a linear motion in the front-rear direction can be alternately applied to the left and right upper limbs of the user holding the gripping portions 81a and 81b. Even when such a handle 80 is used, the center of torsion of the spine 1 is stabilized as in the case of the handle 50 described above.

  As described above, according to the embodiment of the present invention, as described above, the user's spine 1 is twisted to give a repetitive motion between the extended state of the transverse spinous muscle 5 and the extended state, The reduced contractile force of the transverse spinous muscle 5 is activated. After releasing the twist of the spine 1, the strain of the spine 1 can be corrected by the activated contractive force of the transverse spinous muscle 5.
