  The lower side of the side frames 12, 12 is connected by a front crossbar 10, and the lower rear side is connected by a rear crossbar 11. The side frame 12 is configured such that an upper rod member 12A and a lower rod member 12B are integrally fixed. The upper rod member 12A includes a horizontal rod portion 12a extending in the front-rear direction and a rear side end of the horizontal rod portion 12a. A vertical rod portion 12b that rises upward from the portion, and a handle portion 12c that is bent and extends rearward is formed at the upper end of the vertical tube portion 12b.

  An auxiliary wheel 14 is attached to a rear portion of the side frame 12 in the longitudinal direction via an auxiliary wheel support 13. Further, the rear cross bar 11 and the auxiliary wheel support 13 are connected by a rod member 15. Although not described in detail in the drawings, the auxiliary wheel support portion 13 has a vertically divided structure, and members of the divided structure are connected to each other so as to be rotatable in the horizontal direction. The auxiliary wheels 14 are oriented in a turning direction described later.

It functions as a backrest.

  Armrests 24, 24 are fixed to the vertical rods 12b, 12b of the left and right side frames 12, 12 by fixing means 25, 25, respectively. Further, as shown in FIG. 2, a brake device 26 that can be gripped and operated via a fixing means 27 is fixed to the lateral rod portion 12 a of the right side frame 12 in front view. For convenience of description, the brake device 26 is shown only in FIG. 2 and is not shown in other drawings.

  Further, as shown in FIG. 1, a control main body 30 of the operation promoting device 3 described later is detachably fixed to the vertical rod portion 12b on the right side in a front view by support means (not shown). Further, on the lower sheet member 17 side, an electrode device 31 of an operation promoting device 3 described later can be pulled out and arranged.

  The pedals 19, 19 are supported by the pedaling cranks 5, 5, respectively. At a substantially central portion of the main frame 4, one longitudinal side of the shaft member 22 is pivotally supported, and a drive wheel 20 is fixed to the other side of the shaft member 22. The shaft member 22 and the pedaling cranks 5 and 5 are in a transmission relationship by the transmission device 23. According to this, by rotating the pedaling cranks 5, 5, the driving force of the crank is transmitted to the shaft member 22, and the drive wheel 20 fixed to the shaft member 22 rotates. The transmission 23 is a so-called fixed gear without a freewheel, and the rotation of the pedaling cranks 5, 5 is always transmitted to the drive wheels 20 via the shaft member 22 without the free position. Has become.

  The pedaling device 2 includes the lower seat member 17 and the upper seat member 18 as described above, and the pedals 19, 19 are provided forward of the lower seat member 17. Therefore, since the reaction force when the user presses the pedals 19, 19 can be received particularly at the waist and back supported by the upper seat member 18, the pedaling operation is performed by the operation of pushing the legs forward. , The weight is not applied when the pedals 19, 19 are pressed. Therefore, the transmission efficiency of the leg force is stabilized, the burden on the joints such as the waist and the knee is small, and the muscle force of the thigh can be concentrated and increased. Further, since the waist and back are supported by the upper seat member 18 in addition to the lower seat member 17 supporting the buttocks region, the weight can be dispersed over a wide range, and the burden is reduced even when used for a long time, which is suitable for training.

  Subsequently, the operation promoting device 3 will be described with reference to FIGS. 1 and 4 to 6. As shown in FIGS. 1 and 4, the operation promoting device 3 mainly includes a control main body 30 and an electrode device 31. As shown in FIG. 4, the control main unit 30 includes a power supply unit 33 as a battery, a central control unit 34, and an output unit 35 inside a box-shaped exterior member 32.

  The control main unit 30 further includes a power switch 36, an adjustment dial 37, and a changeover switch 38 exposed outside the exterior member 32. The power switch 36 is electrically connected to the power supply unit 33 and the central control unit 34. , The adjustment dial 37 and the changeover switch 38 are electrically connected to the central controller 34, respectively.

  The electrode device 31 mainly includes a wiring 39 and electrode devices 40A and 40B. The wiring 39 is connected to the output unit 35 and is bifurcated in the middle in the longitudinal direction, and has connectors 41 and 41 at the respective ends.

  Hereinafter, since the electrode device 40A and the electrode device 40B have substantially the same structure, the electrode device 40A will be described, and the description of the electrode device 40B will be omitted. The electrode device 40A is in the form of a sheet having a pad portion 40a attached to the skin and a wiring portion 40b extending from the pad portion 40a. The wiring portion 40b is configured by sandwiching a conductive sheet 40d with a nonwoven fabric or the like, and a conductive electrode 40c continuous with the conductive sheet 40d of the wiring portion 40b is exposed on the surface of the pad portion 40a. In addition, one surface of a conductive adhesive member (not shown) is attached so as to cover the electrode 40c, and the other surface is attached to the skin. The performance of the conductive adhesive member is reduced due to the adhesion of secretions and the like to the skin, so that the conductive adhesive member can be appropriately replaced with a new one.

  The connector 41 has a so-called clip-like structure, and fixes and electrically connects the wiring 39 and the wiring portion 40b by sandwiching an end of the wiring portion 40b of the electrode device 40A. As described above, the connector 41 can easily switch between the sandwiched state and the released state of the wiring portion 40b.

  The central control unit 34 can send an electrical stimulation signal to the electrode device 31 from an output unit 35 having a D / A converter at an output determined by the central control unit 34. The adjustment dial 37 is an operation unit that works on the central control unit 34 to adjust the strength of the electric stimulus output from the output unit 35, and the changeover switch 38 works on the central control unit 34 to output the electric stimulus output from the output unit 35. Is an operation unit that switches between a frequency in the range of 0.5 to 3 Hz and a frequency in the range of 20 Hz to 5 kHz.

  FIG. 6 shows a state in which the pad portions 40a, 40a of the electrode devices 40A, 40B of the motion promoting device 3 are directly attached to the skin, respectively, such that the electrodes 40c, 40c are located on both sides of the center line of the sacrum of the user. Is shown. The human pelvis, regardless of gender, is generally composed of a substantially inverted triangular sacrum B sandwiched between a pair of right and left iliac bones (including the iliac bone, the pubic bone, and the sciatic bone). The electrical stimulation wave output from the output unit 35 and applied to the electrodes 40c, 40c is a unipolar negative rectangular wave or a bipolar rectangular wave having a pulse width of 1 to 500 μs, and is a continuous stimulation or a continuous intermittent stimulation.

  In addition, the motion promoting device 3 uses, for example, an electric stimulation frequency in the range of 0.5 to 3 Hz for a person with a walking disorder or a person with difficulty walking, and uses an electric stimulation frequency of 20 to 5 kHz for a healthy person or the like. The electric stimulus frequency is adjusted by operating the changeover switch 38 and operating the adjustment dial 37 as appropriate according to the user's physique and athletic ability. At this time, the output section provides a stimulation output of 20 to 80 volts and a maximum of 100 volts.

  An experiment for measuring the number of rotations of the pedals 19 and 19 per minute when using the pedaling device 2 when the motion promoting device 3 is used and when the motion promoting device is not used for the same subject. As a result, when the operation promoting device 3 was used, the result was that the number of rotations was higher than when the operation promoting device 3 was not used. According to this experiment, by using the motion promoting device 3, the electric stimulation waves applied to the electrodes 40c, 40c are output to both sides of the center of the sacrum B, so that the motor center of the spinal cord is stimulated, and the pedals 19, 19 It was found that it was possible to promote the operation of rowing, that is, the operation of pushing the legs up and then pushing them forward.

  Next, an example of a mode when the training device 1 is actually used will be described with reference to FIGS. 7 and 8. First, the user attaches the pad portions 40a, 40a of the electrode devices 40A, 40B to the skin portions immediately above the center on both sides of the sacrum B (see FIG. 6). The buttocks region is placed on the rear side 17a (seating portion), and the back is left on the upper seat member 18 to be seated.

  Next, the ends of the wiring portions 40b, 40b of the electrode devices 40A, 40B are held between the connectors 41, 41 provided at the ends of the wiring 39 extending from the control main body 30 supported by the pedaling device 2, respectively. The devices 40A and 40B and the control main unit 30 are electrically connected. In this state, the power switch 36 of the control main unit 30 is turned on, and the changeover switch 38 and the adjustment dial 37 are appropriately operated to output the electrical stimulation wave from the output unit 35 (stimulation process). With the electric stimulation wave output, both feet are placed on the two left and right pedals 19, 19 to start pedaling operation.

  As shown in FIGS. 7 and 8, the pedaling operation is an operation in which one leg is pulled upward and then pushed forward (alternatively, left and right). At the time of pedaling operation, the user supports the buttocks region on the rear side 17a (seat portion) of the lower seat member 17 to support most of the load of the human body, and thus extends forward of the buttocks region. A limited movement only in the front-rear direction and in parallel with the two legs that have come out is required, and the muscles of the thighs of the left and right legs in the operation of pedaling the pedals 19 can be effectively strengthened in a well-balanced manner.

  According to this, when the user pedals the left and right two pedals 19 of the foot rowing device 2 with both legs, a pair of left and right electrodes 40c, 40c adhered to the skin immediately above the center on both sides of the sacrum B (FIG. 6), the motor center of the spinal cord is stimulated, and the left and right legs in the operation of pedaling the pedals 19 and 19 are alternately pulled up (in FIG. 7, the right leg is pulled up). The operation of pushing the left and right legs forward alternately (the right leg is pushed forward in FIG. 8) can be facilitated, and the muscle strength of the thighs of the left and right legs can be reduced by the operation of pedaling the pedals 19, 19. The balance can be enhanced. In particular, the use of the motion promoting device 3 enables the user to pad the pedals 19, 19 with both left and right legs by using the motion promoting device 3 as compared with a case where the user walks in rehabilitation. Muscle strength of the thighs of the left and right legs can be enhanced in a well-balanced manner.

  Further, as shown in FIG. 9, by supporting the buttocks region H on the rear side 17 a (seat portion) of the lower seat member 17, the pedaling operation is performed in a state where most of the load of the human body is supported. Therefore, a limited movement only in the front-rear direction and parallel to the legs extending forward of the buttocks region H is required, and the muscles of the thighs in the left and right legs in the operation of pedaling the pedals 19 are balanced. Can be strengthened. In addition, since the reaction force when the pedals 19, 19 are pressed can be received particularly at the waist and back supported by the upper seat member 18, the buttocks region H does not move in the front-rear direction, and particularly, the upper and lower portions of the thighs. Exercise will be promoted efficiently. In addition, H in the figure indicates an area of the buttocks where a load is applied to the rear side 17a (seat portion) of the lower seat member 17 with the left and right front ends I and I of the ischena as centers.

  Furthermore, since the cranks 5 and 5 have a structure in which the relative position in the rotation direction does not change, in the operation of pedaling the pedals 19 and 19, the pedal movement by one leg is always linked to the pedal movement by the other leg. Become. That is, the action of pushing forward with the right leg is the action of pushing backward with the left leg, and together with these linked actions, stimulation of the spinal motor center by the electrical stimulation wave is given, and the training effect is increased. improves.

  9A shows a state in which the pedal 19 is pushed forward by the right leg. At this time, the back side T1 of the thigh of the training user moves forward from the rear side 17a of the lower seat member 17. Left and right alternately contact the front side 17b (extended seat portion) extending. FIG. 9B shows a state in which the pedal 19 is pushed forward by the right leg, and the back side T2 of the thigh is in contact with the front side 17b. Therefore, the downward movement of the knee is restricted by the rear side 1 of the thigh of one leg operated in the direction in which the leg is extended in the pedaling operation, and the downward movement of the knee is restricted. And the movements of the left and right legs can be exercised in a well-balanced manner. In addition, a break can be temporarily given to one leg, and the exercise load on the training user can be reduced.

  As shown in FIGS. 7 and 8, when the user is seated, the position where the lower seat member 17 and the upper seat member 18 of the pedaling device 2 intersect and the portion where the sacrum B of the user is located are slightly different. The space S is formed apart. According to this, since the pad portions 40a, 40a of the motion promoting device 3 are stuck to the skin portions immediately above the central both sides of the sacrum B, they are arranged in this space S. , 40a not only come into contact with the lower sheet member 17 or the upper sheet member 18 through clothes, but also do not come off, and do not feel uncomfortable due to the pad portions 40a, 40a being pressed against the body, and concentrate on training. Can be.

  Further, as described above, since the pedaling device 2 includes the driving wheels 20 that can transmit the driving force of the pedals 19 and 19, and can run, the user can experience a feeling of sprinting during training and do not get bored. Can be used for a long time.

  Further, the wiring 39 extending from the control main body 30 of the operation promoting device 3 and the electrode devices 40A, 40B can be electrically connected to each other by using connectors 41, 41 which are detachable engagement means. The user can easily connect the control device 30 to the electrode devices 40A and 40B, which are previously attached to the skin immediately above the sacrum B on both sides in the center, while sitting on the foot row device 2.

  As shown in FIG. 10, the two pedals 19 of the pedaling device 2 have a measured value of a moving load applied to the pedal 19, that is, a pressed load detected value of the sole over 360 degrees, a load detection time, and , Are simultaneously mounted. The detection unit 45a is, for example, a strain gauge, and the detection value of the pressing load on the sole is measured by the detection unit 45a, and the measured time is simultaneously measured by the clocks in the detection devices 45 and 45. . The detected value of the pressing load on the sole detected by the detecting unit 45a and the time of the load detection detected by the clock in the detecting devices 45 and 45 can be extracted through the output terminal 45b. By comparing and verifying the exercise abilities of the left and right legs due to the pedaling operation from the measurement values taken out via the output terminal 45b, it is possible to take measures to reinforce the left and right legs in a well-balanced manner.

  The measured value of the moving load detected by the detection device 45 (the detected value of the pressing load on the sole and the time of load detection) is graphed by a computer connected to the output terminal 45b by a cable or the like. In the graph shown in FIG. 11, the moving load when the pedal 19 makes one rotation of the crank 5 is expressed as being distributed in a circle around the center point O, and the distance from the center point O and the value of the moving load are represented. Are expressed in proportion.

  As the moving load of one leg (here, the left crank) when the crank 5 is rotated once, a force that is greatly pushed forward in a position near the upper end of the pedal 19, that is, a large moving load, is required. The required force, ie, the moving load, gradually decreases as the pedal 19 moves toward the lower end. Further, the rotation of the pedaling cranks 5, 5 is always transmitted to the drive wheel 20 via the shaft member 22 in a state where there is no free position, and the pedal movement by one leg is always the same as the movement of the other pedal. Since the movements are linked to each other, when one leg (here, the left crank) is located near the upper end, the other leg (here, the right crank) is located near the lower end. Since the other leg is rotated in the upper end direction by the driving force generated by the pedaling operation of the one leg, the moving load is reduced. Therefore, when both the left and right legs perform the pedaling operation in a well-balanced manner, a substantially tear-shaped shape having a smooth curve as shown in FIG.

  On the other hand, when the balance of the pedaling operation of the left and right legs is poor, for example, when the other leg pushes the pedal 19 forward, if one leg does not balance with the other leg and does not move normally, This leg acts as a reaction force to hinder the rowing operation of the other leg, and the shape of the graph collapses (see FIG. 11B). Therefore, this graph is verified, and the muscular strength required for walking the thigh in the user's foot rowing motion is balanced by the degree of approximation of the smooth curve as shown in FIG. It is possible to judge whether or not it is close to the ideal pedaling operation that works well.

  Note that the detection devices 45, 45 and the computer may be connected by wireless communication or the like, and the measured value of the moving load detected by the detection devices 45, 45 may be transmitted to the computer instantaneously. In the case of such a configuration, the data of the measured value of the moving load when the predetermined left and right legs perform the pedaling operation in a well-balanced manner and the data of the measured value of the actually detected moving load are used.
