  In the apparatus disclosed in Patent Documents 1 and 2, an apparatus that attempts to obtain an effect such as exercise of a muscle mainly by applying exercise to a user's trunk, and an exercise apparatus that applies correction exercise to the spine. Absent. On the other hand, the device disclosed in Patent Document 3 is a device that attempts to obtain an effect of correcting the rib cage or the like by “pushing acupuncture points”. It is not a spinal correction exercise device to be applied to.

  An object of the present invention is to provide a spinal correction exercise apparatus capable of efficiently and passively imparting corrective movements of the thoracic vertebra and lumbar vertebra in the spine while standing from the upper and lower limbs. is there.

  The inventor has come to make the present invention from the experience of researching chiropractic for more than 30 years.

  An exercise device according to the present invention is a spinal correction exercise device for imparting a correction exercise to a thoracic vertebra and a lumbar vertebra in a user's spine, wherein the tread plate moves up and down alternately left and right across a central axis, and the tread plate A pair of handles provided on the left and right sides of the central axis and reciprocating back and forth along the direction of the central axis. In a state where the pair of handles are arranged upright on the stepping plate on the stepping plate with the shaft sandwiched therebetween and faced forward along the central axis direction, the pair of handles reciprocate directly above the outside extension of the stepping portion, The reciprocating motion is characterized in that it moves with respect to the human body.

  According to the apparatus of the present invention, the user can use the left and right vertical movements from the lower limbs from the power source such as a motor to the spine through the pelvis, From the upper limb, back and forth movement is given to the spine passively from a power source such as a motor through the rib cage. In addition, since the user is in a standing position on the tread board, downward stress from the head is applied to the spine so that the vertebrae of the spine are in close contact with each other. Therefore, the above-mentioned movements from the upper limbs and the lower limbs can efficiently and stably co-operate near the connection points of the thoracic vertebra and the lumbar vertebra, which are discontinuous points of the spine. In other words, since the user is relaxed without using his / her power due to the passive motion, corrective motions of the thoracic vertebra and lumbar vertebra in the spine can be efficiently applied.

  In the above invention, the pair of handles are reciprocated by a power source such as a motor in an area on the tread plate. According to such an invention, the user can maintain the posture in which the rib cage is opened, and the forward and backward movement can be reliably applied to the spine from the upper limb through the rib cage.

  In the above invention, the tread plate is operated as a seesaw with the central axis as a rotation axis. According to this invention, the left and right of the lower limb can be exercised regularly in the opposite phase alternately up and down, and exercise can be imparted evenly to the lower limb.

  Further, in the above invention, the pair of handles can be arranged at a height between a waist portion and a shoulder portion of the user. According to this invention, the user is standing and holding the handle on the side of the trunk, the rib cage is opened, and the back and forth movement is reliably given to the spine from the upper limb through the rib cage.

  In the above invention, the pair of handles is further characterized by being substantially perpendicular to the tread plate and reciprocating in parallel while maintaining this. According to this invention, the user holds the handle with the back of the hand facing outward to maintain the elbow joint in an intermediate position, and the forward / backward movement is reliably given from the upper limb to the spine through the rib cage.

  In another aspect of the present invention, the pair of handles are substantially horizontal with respect to the tread plate, and reciprocate in parallel while maintaining this. According to this invention, the user can move the back and forth motion from the upper limb to the spine through the rib cage while holding the handle with the back of the hand upward or downward and holding the elbow joint in the pronation or supination position. It is given to.

  In the invention described above, the pair of handles reciprocate in opposite phases. According to this invention, the motion introduced into the user's upper limb is given alternately to the left and right, and the motion can be stably applied to the spine.

  In another aspect of the invention, the pair of handles reciprocate in the same phase. According to this invention, the motion introduced into the user's upper limb is given equally to the left and right, and the motion can be stably imparted to the spine.

  In another aspect of the invention described above, the pair of handles reciprocate the other while stopping one. According to this invention, a motion can be stably given to the spine.

  In the above invention, the reciprocating motion of the handle and the vertical motion of the tread plate are synchronized. According to this invention, the cooperative motion in the vicinity of the connection point of the thoracic vertebra and the lumbar vertebra obtained by the motion introduced from the lower limbs and the motion introduced from the upper limbs is given more stably.

  First, the principle of the effect on the user of the spinal correction exercise apparatus according to the present invention will be described.

  As shown in FIG. 1, the spinal correction exercise device according to the present invention introduces a vibration exercise F <b> 1 that alternately moves the pelvis 1 up and down through the hip joint K from the lower limbs. On the other hand, from the upper limb, a vibration motion F2 for moving the shoulder joints D back and forth is introduced. Here, the user P is in a standing position, and the spine E is given a downward stress g from the head H, so that the vertebrae e of the spine E can be in close contact with each other. Thereby, the movement from the lower limbs and the movement from the upper limbs can be guided to the spine E. In particular, exercise F1 from the upper limbs is achieved by bringing the vertebrae e constituting the thoracic vertebrae B above the spine E having a high degree of movement allowance mainly in order to engage in lateral bending and rotation of the trunk into close contact with each other. Can be transmitted without being absorbed between the vertebrae e.

  By the way, since the lumbar vertebra G in the lower part of the spine E is mainly involved in the trunk bending forward and backward, the lateral movement of the vertebrae e constituting the lumbar vertebra G is restricted, and the lateral movement from the lower limbs is absorbed. This can be propagated without The left-right motion is released at a connection point (a connection point between the first lumbar vertebra G1 and the twelfth thoracic vertebra B1) with the thoracic vertebra B having a different function and structure from the lumbar vertebra E. Therefore, the vicinity of the discontinuous point can be moved together with the longitudinal movement from the upper limb.

  Furthermore, when the position of the shoulder joint D where the upper and lower limb movements are introduced and the both ends of the pelvis I are connected to each other by the spinal correction exercise device according to the present invention, such a discontinuous point is located at the intersection. Therefore, the discontinuous points can be moved together efficiently and stably.

「関節の生理学 体幹・脊柱」、第８６頁、２００５年１１月発行、医師薬出版株式会社）からもわかるように、身体機能の維持において第１２胸椎近傍の役割は大きく、当該部分の矯正は脊椎の矯正の中でも非常に重要である。Such corrective movement by the above-mentioned cooperative movement in the vicinity of the first lumbar vertebra G1 and the twelfth thoracic vertebra B1 gives a high improvement effect of various body functions. In particular, it provides an effect of improving functions related to the small intestine, oviduct, and lymphatic circulation. “The 12th thoracic vertebra is the midpoint between the lumbar and thoracic vertebral folds. In fact, the 12th thoracic vertebra acts as a rotating device, and its thrust is firmer than the bow, and The spinal muscles that are running for a long time without adhering to the body cover the back.

As can be seen from “Physiology of the joint, trunk / vertebral column”, page 86, published November 2005, Physicians and Drugs Publishing Co., Ltd. Is very important in spinal correction.

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

  As shown in FIG. 2, the spinal correction exercise device 1 includes a lower limb exercise unit 1 a installed on the floor surface and an upper limb exercise unit 1 b located above the lower limb exercise unit 1 b.

As a result, the tread plate 19 performs a seesaw movement with the shaft 20 (center axis M) as the rotation axis. In the vicinity of the step portions 24a and 24b of the above-described stepping plate 19, the stroke of the vertical movement is preferably 3 cm or less.

  Referring again to FIG. 2 together with FIGS. 6 to 10, the upper limb motion portion 1 b includes a substantially rectangular parallelepiped housing 15, and an upper end portion of a column 16 erected in front of the housing 18 of the lower limb motion portion 1 a. Is attached. The upper limb motion part 1 b is movable along the support column 16.

  Specifically, as shown in FIG. 6 in particular, the height adjustment mechanism 17 for adjusting the height with respect to the lower limb movement part 1a is provided inside the housing 15 and is provided with a rack gear provided along the support column 16. It consists of a worm gear, a motor, etc., and is controlled by the height controller 105.

  Referring again to FIG. 2 in particular, the front surface A of the housing 15 is provided with a substantially rectangular opening 3 extending along the X-axis direction. A pair of arms 5a1 and 5b1 made of a metal square pipe or a metal round pipe are inserted into the opening 3 so as to be substantially perpendicular to the surface A, spaced apart from each other in the width direction. Joints 40a and 40b, which will be described later, are attached to the rear ends of the arms 5a1 and 5b1.

  On the other hand, as shown in FIG. 7 in particular, pin ends 54b (54a) are provided at the projecting ends of the pair of arms 5b1 (5a1) from the housing 15 so that the openings are directed upward, and pin screws 53b are provided. The pair of handles 5a and 5b are attached by (53a). Specifically, in the vicinity of the end portion of the handle 5b (5a), there is a bent fitting portion 5b4 (5a4), and the outer dimension thereof is slightly smaller than the inner dimension of the arm 5b1 (5a1). The fitting portion 5b4 (5a4) has a screw hole 51b (51a) along the longitudinal direction of the handle 5b (5a) and a screw hole 52b (52a) provided in a direction perpendicular thereto. Although not shown, the screw hole 52a is located on the opposite side (+ X side) of the screw hole 52b. The fitting portions 5b4 (5a4) of the handle 5b (5a) are respectively inserted into the arms 5b1 (5a1) and fixed by the pin screws 53b (53a) through the pin holes 54b (54a). Here, when the pin hole 54 b (54 a) and the screw hole 51 b (51 a) are communicated and the pin screw 53 b (53 a) is inserted, the handle 5 b (5 a) is substantially perpendicular to the tread plate 19. Placed in. On the other hand, when the pin hole 54b (54a) and the screw hole 52b (52a) are communicated and the pin screw 53b (53a) is inserted, the handle 5b (5a) is parallel to the tread plate 19, that is, substantially horizontal. Placed in. In addition, the screw holes 51b (51a) can be appropriately provided to change the arrangement of the handles 5b (5a).

  Referring again to FIGS. 6 and 8, the guide ring 6 a (6 b) is a rectangular tube that extends along the Z axis, and is fixed to the inner wall 15 a in the housing 15. A piston 4a (4b) is slidably inserted along the Z axis inside the guide ring 6a (6b). A width adjusting arm 4a1 (4b1) that is bent toward the side is provided at a forward projecting end portion of the piston 4a (4b) from the guide ring 6a. A rack gear 4a2 (4b2) is carved on the back surface of the width adjusting arm 4a1 (4b1).

  In particular, as shown in FIG. 9, the joint 40a (40b) has a mounting hole 41a (41b) at the front, and an arm 5a1 (5b1) can be inserted into the joint 40a (40b) and fixed with screws 44a (44b). . At the center of the joint 40a (40b), there is a square hole 42a (42b) extending along the X axis, and the width adjusting arm 4a1 (4b1) is slidably inserted. A window 43a (43b) communicating with the square hole 42a (42b) is provided behind the joint 40a (40b), and the rack gear 4a2 (4b2) provided on the width adjusting arm 4a1 (4b1) faces outward. Naked. In the vicinity of the window 43a (43b), a width adjustment mechanism 5a2 (5b2) including a worm gear and a motor that meshes with the rack gear 4a2 (4b2) of the width adjustment arm 4a1 (4b1) is attached. The width adjusting mechanism 5a2 (5b2) is controlled by the handle width control unit 104 and can move the joint 40a (40b) along the width adjusting arm 4a1 (4b1).

  Referring to FIGS. 6 and 10 in particular, the crank arm 8a (8b) is a rod-shaped member in which one side of a square bar is rounded. The crank arms 8a and 8b have flat surfaces 82a and 82b opposite to the rounded surfaces 81a and 81b facing each other, and are connected to the center in the longitudinal direction by the rotating shaft 14 to form a substantially H-shaped member. (See also FIGS. 13 and 14). The rotary shaft 14 is pivotally supported by a support member (not shown) so as to extend along the X axis. That is, the crank arms 8a1 and 8b1 are rotatable around the rotation axis R on which the rotation shaft 14 extends. The rotating shaft 14a engages with a power transmission unit 10 including a reduction gear using gears, pulleys, and the like, and is further connected to the driving unit 11 to rotate the crank arms 8a and 8b by the driving force of the driving unit 11. Rotate around the axis R. The drive unit 11 includes a motor that can control the rotation speed, and can be controlled by the lower motor control unit 101.

The slide member 9a (9b) is fitted along the longitudinal direction of the crank arm 8a (8b) so as to embrace it from the rounded surface 81a (81b) of the crank arm 8a (8b). A rack gear 8a1 (8b1) is cut on the side surface 83a (83b) of the crank arm 8a (8b), and is exposed to the outside through the window 9a2 (9b2) of the slide member 9a (9b). A worm gear 26a (26b) meshing with the rack gear 8a1 (8b1) and a stroke control motor 25a (25b) for rotating the rack gear 8a1 (8b1) are attached in the vicinity of the window 9a2 (9b2). The rotation angle of the stroke control motor 25 a (25 b) is controlled by the stroke control unit 103. Thereby, the distance from the rotating shaft R of the slide member 9a (9b) can be made variable. That is, as will be described later, the reciprocating stroke of the piston 4a (4b) can be adjusted.

The front end of the connecting rod 7a (7b) is pivotally attached to the rear end of the piston 4a (4b). Further, the rear end portion of the connecting rod 7a (7b) is pivotally attached to the pin 9a1 (9b1) of the slide member 9a (9b).

In particular, as shown in FIG. 11, by operating a panel-like operation unit 13 ′ (see FIG. 2) provided on the surface A of the casing 15, the lower motor control unit 101 and the upper motor control are controlled from the central control unit 13. A control signal is sent to each of the section 102, the stroke control section 103, the handle width control section 104, and the height control section 105.

Next, the usage method and operation | movement of the spinal correction exercise | movement apparatus 1 are demonstrated in detail using FIG. 1 to FIG.

In particular, as shown in FIG. 13, when the user P operates the operation portion 13 '(see FIG. 1), the slide members 9a and 9b move to positions facing each other on the crank arms 8a and 8b. That is, it moves to the position of the same distance from the rotation axis R. In addition, the distance from the rotating shaft R of the slide members 9a and 9b determines the stroke width of the back-and-forth movement of the handles 5a and 5b. Specifically, referring further to FIG. 11, the central control unit 13 that has received a signal from the operation unit 13 ′ operates the stroke control motors 25 a and 25 b via the stroke control unit 103. As a result, the worm gears 26a and 26b rotate, and the slide members 9a and 9b are moved along the crank arms 8a and 8b while meshing with the rack gears 8a1 and 8a2.

  Here, referring further to FIG. 6, in the initial state, the crank arms 8a and 8b are arranged so that the pins 9a1 and 9b1 are located farthest from the surface A. At this time, the handles 5a and 5b are arranged at the front position which is the maximum movement position in the + Z direction.

Next, as shown in FIG. 12, the user P stands upright with his / her back on the step portions 24a and 24b (see FIG. 2) of the tread 19 so as to face the surface A of the upper limb motion portion 1b (see FIG. 2). This is called “standing position”). When the upper arm is lowered along the trunk with the shoulder width and the elbow joint is moved backward with the shoulder joint as the center, the chest is opened and the chest is stretched. In this state, when the forearm is leveled around the elbow joint, the hand (palm) is positioned slightly in front of the thorax. Since the handles 5a and 5b are at least in the upper region of the tread plate 19, that is, directly above the side portions of the step portions 24a and 24b, when the height is adjusted to the height position of the hand of the user P, the posture described above naturally You will be able to grasp this.

  For the adjustment, the operation unit 13 'is operated.

  The user P can adjust the interval between the handles 5a and 5b by operating the operation portion 13 '. Specifically, as shown in FIGS. 8 and 11, when the operation unit 13 ′ is operated, the central control unit 13 sends a signal to the handle width control unit 104 to operate the worm gears of the width adjusting mechanisms 5a2 and 5b2. . Then, the arms 5a1 and 5b1 move in the X-axis direction along the width adjusting arms 4a1 and 4b1, and the distance between the handles 5a and 5b can be adjusted.

  Further, the user P can adjust the heights of the handles 5a and 5b by operating the operation unit 13 '. Specifically, as shown in FIGS. 6 and 11, when the operation unit 13 ′ is operated, a signal is sent from the central control unit 13 to the height control unit 105, and the worm gear of the height adjustment mechanism 17 operates. The upper limb motion part 1b moves in the vertical direction along the support column 16.

  Further, the user P can change the orientation of the handles 5a and 5b as desired as described above with reference to FIG. Here, when the handles 5a and 5b are oriented in the vertical (Y-axis) direction, the elbow joint of the user P is in an intermediate position with the thumb facing upward, and the gripping method places a small burden on the wrist joint. When the handles 5a and 5b are oriented in the horizontal (X-axis) direction, the handles 5a and 5b are gripped from below and the thumb is directed outward, and conversely, the handles 5a and 5b are gripped from above and the thumb is Can be inwardly oriented toward the inside.

  Here, as shown in FIGS. 15 and 16, the hand T can be bent at the wrist Q with respect to the forearm U. When the hand T holding the rod S is bent toward the little finger side, it can be bent greatly, but the movable range on the thumb side is narrow. In other words, in the pronation position, the elbow cannot be spread unless the wrist is bent to the thumb side. On the other hand, in the pronation position, the wrist is bent toward the little finger side, so that it is easier to spread the elbow than in the pronation position. Therefore, when it is in the supination position, it is difficult to spread the elbow to the side, so that the rib cage can be opened further, and the reciprocating motion of the handles 5a and 5b can be transmitted to the shoulder joint D efficiently. Moreover, since it becomes easy to spread an elbow to the side if it is a pronation position, the load concerning the shoulder joint D can be reduced.

  Subsequently, the user P operates the operation unit 13 'to start the footboards 19a and 19b of the lower limb motion unit 1a at a desired frequency, preferably in the range of 2 to 22 Hz. Specifically, referring to FIGS. 3 and 11, when the operation unit 13 ′ is operated, power is supplied from the central control unit 13 to the drive unit 23 via the lower motor control unit 101. The rotational speed of a motor (not shown) can be changed by operating the operation unit 13 ′ even after starting, and can be changed and set by a signal from the central control unit 13. The driving force obtained by the driving unit 23 rotates the crank disk 30 via the power transmission unit 21. The rotation of the crank disk 30 is converted by the connecting member 33 into a movement that moves both ends of the tread plate 19 in the X-axis direction up and down with respect to the central axis M. Therefore, the tread board 19 is moved by the seesaw. Since the step portions 24a and 24b are provided symmetrically with respect to the central axis, they move in conjunction with each other in opposite phases.

  The movement of the tread board 19 gives an exercise of alternately moving the left and right of the pelvis up and down via the lower limbs J of the user P. Normally, the bending of the knee by the user P is an absorption of the exercise to the knee. It is difficult to increase the load.

  Next, the user P operates the operation unit 13 'to start the handles 5a and 5b of the upper limb motion unit 1b in a desired frequency, preferably in the range of 2 to 22 Hz. Specifically, referring to FIGS. 6 and 11, when the operation unit 13 ′ is operated, electric power is supplied from the central control unit 13 to the drive unit 11 via the upper motor control unit 102. The number of rotations of a motor (not shown) can be changed by operating the operation unit 13 ′ even after starting, and can be changed and set by a signal from the central control unit 13. The driving force obtained by the driving unit 11 rotates the crank arms 8 a and 8 b via the power transmission unit 10. The rotational movement of the crank arms 8a and 8b is converted into a reciprocating motion before and after the handles 5a and 5b via the connecting rods 7a and 7b.

  Here, when the crank arms 8a and 8b are rotated halfway from the initial position described above, the pins 9a1 and 9b1 move to a position closest to the surface A of the upper limb motion part 1b. That is, the handles 5a and 5b are arranged at the rear position which is the maximum movement position in the -Z direction. The forearm of the user P moves together with the handles 5a and 5b almost in parallel from the front position to the rear position. Therefore, the elbow joint cannot absorb such movement, and the forearm is pushed rearward so that the elbow joint is horizontal. It can be moved. That is, the user P is pushed backward from the posture in which the thorax is opened with the shoulder joint D of the upper arm hardly rotating, and the shoulder joint D is also moved rearward, so that the thorax is further opened. . If an excessive load is likely to occur on the shoulder joint D or the rib cage of the user P, the trunk of the user P can be avoided by being pushed back to the back side.

  Further, when the crank arms 8a and 8b are rotated halfway, the pins 9a1 and 9b1 are returned to the positions farthest from the surface A again, and the handles 5a and 5b are arranged at the front position. That is, the user P returns to the initial state again.

  Note that the user P can also change the strokes of the above-described longitudinal movements of the handles 5a and 5b by changing the distances from the rotation axis R of the slide members 9a and 9b by operating the operation unit 13 '. Specifically, referring to FIGS. 11, 13, and 14, when the operation unit 13 ′ is operated, the stroke control motor 25a (25b) and the worm gear 26a (26b) are operated from the central control unit 13 via the stroke control unit 103. ) Can be operated to change the position of the slide member 9a (9b) with respect to the crank arm 8a (8b). The reciprocating stroke of the piston 4a (4b) is double the distance between the rotation axis R and the pin 9a1 (9b2). Here, the stroke of the reciprocating motion of the piston 4a (4b) is preferably about the thickness of the rib cage of the user P, for example, 8 cm or less, preferably about 2 to 3 cm. If the width of the reciprocating motion is too large, the motion F2 applied to the shoulder joint D becomes too large, and an excessive load is applied to the user's trunk. Moreover, the tolerance of each part of the trunk with respect to the exercise | movement given to the user P will arise, and the effect of continuous exercise will be reduced.

  Here, the movements of the handles 5a and 5b can be reversed in phase. Similarly to the above, the slide member 9b is moved on the crank arm 8b via the stroke control unit 103 so that the slide member 9b is positioned on the opposite side across the rotation shaft R with the operation of the operation unit 13 ′. is there. According to this, when the handle 5a is in the front position, the handle 5b is in the rear position. Conversely, when the handle 5a is in the rear position, the handle 5b is in the front position.

  As described above, according to the present apparatus, the frequency of the reciprocating movement of the handles 5a and 5b and the frequency of the seesaw movement of the tread plate 19 can be adjusted independently, and the body P of the user P can be adjusted. For example, the frequency of the handles 5a and 5b may be the same as the frequency of the tread plate 19, or the phase of the handle 5a and the handle 5b may be reversed so that the phase of the upper position of the step portion 24a is the front position of the handle 5a. Alignment can be reversed to the front position of the handle 5b. Furthermore, the frequency of the handles 5a and 5b and the frequency of the tread plate 19 are different, and the phase does not have to be synchronized. Furthermore, according to the chiropractic expert, it is possible to finely adjust the movement of the upper limb and the lower limb while observing the state of the spine of the user P from the outside.

  Of course, it is also possible to input a signal so as to drive only one of the drive units 11 and 23 by the operation unit 13 'and exercise only one of the upper limbs and the lower limbs. It is also possible to use it as an exercise device that gives

  As described above, according to the present invention, correction movements of the thoracic vertebrae and the lumbar vertebrae in the spine as described above can be efficiently applied by movements such as “vibration” applied to the upper and lower limbs.

  Furthermore, while giving exercise | movement to the spine E inside a trunk, the effect which trains the deep muscle inside a trunk can also be expected. Moreover, effects such as improvement of physical functions can be expected by enhancing muscle strength of the trunk.

  As another embodiment, the handles 5a and 5b may be reciprocated alternately by providing a cam mechanism instead of the crank arms 8a and 8b. That is, from the state where the handles 5a and 5b are stopped at the front position, only the handle 5a is reciprocated from the rear position to the front position and stopped. Subsequently, only the handle 5b reciprocates from the rear position to the front position and stops. Since the mechanism is almost the same as the above-described embodiment, the details are omitted. Such alternate reciprocating motion can also stably impart motion to the spine.

  The step portions 24a and 24b and the handles 5a and 5b are passively moved with respect to the human body by a power source such as a motor, and the human body is passively moved.

  In the above-described embodiments, design values such as dimensions and movements of each part of the apparatus should be determined in consideration of the user's physique and the like. Therefore, the design values and shapes of the respective parts of the present apparatus are not limited to the above-described embodiments as long as they have the gist of the present invention and the effects and functions to be achieved.
