Abstract
Description
[Technical Field]
[0001] The present invention relates to a training device used by persons with disabilities in the motor functions of their upper and lower limbs for training to restore motor functions, and more specifically to a training device that allows comprehensive training including upper and lower limbs to be performed while the person is seated in a wheelchair or chair. [Background technology]
[0002] Traditionally, patients with impaired motor function in their lower limbs often use training equipment such as leg presses to train their lower limbs. However, transferring patients from their wheelchairs to training equipment can pose a physical burden and risk of falls for both the therapist and the patient. Furthermore, using a leg press can require support to maintain balance, which poses a safety risk.
[0003] Therefore, Patent Document 1 proposes a lower limb training device that allows patients with impaired motor function of the lower limbs to train their lower limbs while sitting in a wheelchair.The lower limb training device has left and right pedals that are slidably mounted on sliding sections to fix the patient's feet when approaching the device and bending and straightening the lower limbs.

DETAILED DESCRIPTION OF THE INVENTION
[0056] [First embodiment] Next, an embodiment of the present invention will be described with reference to the accompanying drawings.
[0057] Overall configuration of the training device 1 of the first embodiment 1 is a perspective view showing the overall external configuration of a training device 1 according to a first embodiment. The training device 1 is used by detachably connecting a wheelchair, and allows the wheelchair user to train while sitting in the wheelchair 2. In FIG. 1, the training device 1 comprises a main frame 10, a footrest 11, a sliding section 20, a wheelchair connecting section 21, a swing lever 31, and a terminal unit 50.
[0058] The main frame 10 is a box-shaped base that supports the entire training device 1, including the wheelchair 2. Adjusters 13 are attached to the four corners of the main frame 10 to adjust for floor wobble and tilt and keep the device level. Footrests 11 are provided integrally with the main frame 10 on the front side of the main frame 10 and are used to secure the feet of a trainee using a wheelchair. The footrests 11 have retaining belts 14 on each side of the foot, and the feet are secured to the footrests 11 by the retaining belts 14. The footrests 11 are configured so that their height and angle can be adjusted to suit the trainee's physique. The width of the footrests 11 is set to fit between the footrests of a typical wheelchair 2 when the footrests are folded down.
[0059] The slide section 20 as a slide mechanism holds the entire wheelchair, including the front and rear wheels of the wheelchair 2, in an upright position, and is provided on the main body frame 10 so that it can slide back and forth relative to the footrest (see Figs. 1 and 2). As shown in Fig. 2, a slide holder 115 that holds the slide section 20 slidably on the main body frame 10 has sliders 116 on the left and right outer walls of the slide section 20, and the sliders 116 are supported by rails 117 laid on the left and right inner walls of the main body frame 10 so that they can move back and forth.
[0060] As shown in Fig. 1, the training device 1 includes a biasing mechanism 12 that biases the sliding section 20 toward the footrest 11. The biasing mechanism 12 includes coil springs 12a, 12b, 12c, and 12d that connect the main frame 10 and the sliding section 20 so that tension acts on the sliding section 20 to bias the sliding section 20 toward the footrest 11. The biasing mechanism 12 also includes a biasing force adjustment means that can adjust the biasing force. In Fig. 1, of the coil springs 12a, 12b, 12c, and 12d, the front end of the coil spring 12c is fastened to the main frame 10 with a screw, and the rear end is fastened to the sliding section 20 with a screw, so that only the coil spring 12c is installed between the main frame 10 and the sliding section 20. In contrast, the front and rear ends of coil springs 12a, 12b, and 12d are all screwed to main body frame 10, so no urging force acts on footrest 11 of slide section 20. In this case, the urging force on footrest 11 of slide section 20 acts only on coil spring 12c. Increasing the number of the four coil springs that are screwed between main body frame 10 and slide section 20 increases the urging force.
[0061] According to this, since the biasing mechanism 12 that biases the sliding portion 20 toward the footrest 11 is provided, the sliding portion 20 can be repeatedly slid back and forth relative to the footrest 11 with a simple configuration. Moreover, the biasing mechanism 12 includes coil springs 12a, 12b, 12c, and 12d that connect the main frame 10 and the sliding portion 20 so that tension that biases the sliding portion 20 toward the footrest 11 acts on the sliding portion 20, so the sliding portion can be repeatedly slid back and forth relative to the footrest with a simple configuration. A positive load can be applied by the training action of moving the sliding portion 20 in a direction away from the footrest 11. Moreover, since the biasing mechanism 12 has a biasing force adjustment means that can adjust the biasing force, the movement load of the sliding portion 20 can be adjusted to suit the trainee's symptoms.
[0062] The wheelchair coupling section 21 couples the wheelchair 2 to the sliding section 20 with the front and rear wheels of the wheelchair 2 riding up onto the sliding section 20 and supporting the entire wheelchair. As shown in Figure 5, the wheelchair coupling section 21 is equipped with a plurality of locking members 22, each of which has a hook 23 at the end of a belt 24 that can be locked to a location on the wheelchair 2 to be locked, and a buckle 25 for adjusting the length of the belt 24, one end of the belt 24 of the plurality of locking members 22 being fixed to a predetermined position on the sliding section 20 by a fixing section 26, and the other end of the belt 24 being attached to the wheelchair 2 by the hook 23. After the hook 23 is attached to the wheelchair 2, the length of the belt 24 can be adjusted by the buckle 25, thereby fixing and coupling the wheelchair 2 to the sliding section 20.
[0063] The swing levers 31 are installed on both the left and right sides near the footrest 11. The swing levers 31 are provided so as to be swingable in the front-to-rear direction around the lower end of the swing lever 31 as the swing center. A grip 32 is provided at the upper end of the swing lever 31 so that the trainee can grip it with their hands during training. A pair of transmission units 30a, 30b are provided on the left and right sides to transmit the swinging motion of the swing lever 31 to the slide unit 20. The transmission unit 30a shown on the left side of FIG. 1 is formed by a link mechanism. The upper end of a link member 33 constituting the link mechanism is rotatably connected to the middle of the swing lever 31 by a pin 331, and the lower end of the link member 33 is rotatably connected to the upper surface of the slide unit 20 by a pin 332. When the swing lever 31 is tilted and swung backward from the upright position shown in FIG. 1 to the position shown in FIG. 2 by the transmission unit 30a, the slide unit 20 is moved backward. The sliding portion 20 can be moved rearward by tilting the swing lever 31 against the biasing force of the biasing mechanism 12. The transmission portion 30b shown on the right side of Fig. 1 has basically the same configuration as the transmission portion 30a, so a description thereof will be omitted. The swing lever 31 is configured so that the height of the grip 32 and the tilt angle during the swinging motion can be adjusted to suit the trainee's physique.
[0064] The terminal unit 50 is installed on the right side of the footrest 11. The rear edge of the terminal unit 50 is aligned with a reference position where the lower end of the footrest 11 is fixed to the main frame 10. The terminal unit 50 has a distance sensor 16 as a detector for measuring the distance between the reference position and the sliding portion 20 when it slides backward. The distance sensor 16 measures distance by measuring the time it takes for a pulsed laser to hit an object and return, and converting the time into distance. Note that the detector is not limited to the distance sensor 16 and may be, for example, a combination of an optical sensor and an encoder. The terminal unit 50 also includes a transmitter 300 (see FIG. 6) for wirelessly transmitting distance data detected by the detector to an external device. The distance data detected by the detector is transmitted to a user terminal via the transmitter 300, and the trainee can train based on a dedicated app on the user terminal. The user terminal may be a smartphone, tablet, or PC. In addition, the dedicated app is configured to issue an alert such as a chime or buzzer when the distance data detected by the detection unit reaches a value preset by a caregiver such as a physical therapist.
[0065] As described above, since the device further includes a detector that measures the distance the sliding portion 20 slides from a reference position and a transmitter 300 that wirelessly transmits data on the distance traveled from the detector, by measuring the distance traveled by the sliding portion with the detector, the amount of exercise can be grasped as a numerical value, which is a measure of the distance traveled, and it is possible to accurately monitor whether the target exercise index is being achieved. In addition, since the exercise results can be seen in numerical values, the effects of daily training and training can be easily understood, which leads to increased motivation.
[0066] Furthermore, since the detection unit is a distance measuring sensor 16 installed at a reference position corresponding to the installation position of the footrest portion 11, it is possible to detect even if the sliding portion 20 moves to a position more than a predetermined distance away from the installation position of the distance measuring sensor 16, and the distance from the reference position to the sliding portion 20 can be measured appropriately.
[0067] Furthermore, the data on the distance traveled is transmitted to the user terminal 41 via the transmitting unit 300, and the training of the trainee is recorded based on a dedicated app on the user terminal 41. Therefore, as a training system comprising the training device 1 and the user terminal 41, training can be properly performed and recorded, and the monotony of exercise can be eliminated while being inexpensive and occupying a small space.
[0068] Furthermore, since the user terminal 41 is a smartphone, tablet, or personal computer, a training system equipped with the training device 1 and the user terminal 41 can be constructed using a terminal device that the user has nearby, and the training system is inexpensive, occupies a small space, and can eliminate the monotony of exercise.
[0069] [Control System] 6, a control unit 70 on the transmitting unit 300 side in the terminal unit 50 has a CPU 701, a memory 702, etc., and is connected to the control unit 70 with a distance measuring sensor 16, a transmitting unit 707, and an alarm unit 703. Furthermore, a switch 706 and a battery 705 are connected to the control unit 70 via a power supply control unit 704. Also, a control unit 71 on the receiving unit 400 side as the user terminal 41 has a CPU 711, a memory 712, etc., and is connected to the control unit 71 with a receiving unit 716, a display unit 714, an operation unit 715, and an alarm unit 713.
[0070] As shown in FIG. 6, the distance measurement sensor 16 is connected to the transmitter 300 via the control unit 70. When the switch 706 is turned on, power is supplied from the battery 705 to the distance measurement sensor 16 and the transmitter 300. This causes the transmitter 300 to wirelessly transmit the signal from the distance measurement sensor 16. More specifically, the transmitter 300 converts the analog signal from the distance measurement sensor 16 into a digital signal. The transmitter 300 then samples the digital signal (distance data) at regular intervals and transmits it to the receiver 400 using the Bluetooth (registered trademark) communication standard. The receiver 400 (control unit 71) monitors the set distance and counts the number of times the slider has reciprocated based on the distance data.
[0071] [Training movement 1] Next, how to use the training device 1 will be described.
[0072] When using the training device 1, the trainee sits in the wheelchair 2, and a therapist or the like moves the wheelchair 2 from behind toward the training device 1, and as shown in Figure 3, the entire wheelchair, including the front and rear wheels, rides onto the sliding section 20. Then, in this state, the wheelchair 2 is connected to the sliding section 20.
[0073] As shown in Figure 5, the lower ends of the left and right belts 24 are fixed to fixing parts 26 at a predetermined position that is the center of the rear edge of the sliding part 20 in the left-right direction. The upper ends of the belts 24 are attached to the rear of the wheelchair 2 with hooks 23. The length of the belts 24 is then adjusted with buckles 25. The wheelchair 2 is detachably connected to the sliding part 20. The wheelchair connecting parts 21 may be installed at multiple locations on the slider 116.
[0074] According to this, the wheelchair 2 is detachably connected to the main frame 10 by a length-adjustable belt 24 with a hook, so that the wheelchair 2 can be easily attached to the training device 1 and the wheelchair 2 that can be attached is versatile.
[0075] Next, the trainee places his / her feet on the footrests 11 provided on the front side of the main frame 10. Next, both feet are fixed to the footrests 11 with the holding belts 14. Then, the trainee grasps both grips 32 at the tip of the swing lever 31 with both hands.
[0076] At the start of training, the trainee takes the posture shown in Figure 3, with both lower limbs bent and both upper limbs extended forward, grasping both grips 32 of the rocking lever 31. At this time, the rocking lever 31 is aligned in a vertical direction that is approximately perpendicular to the horizontal plane.
[0077] Next, when the trainee extends both lower limbs from the posture shown in Figure 3 and attempts to move the entire body backward away from the footrest 11 using the muscle strength of both lower limbs, the wheelchair 2 moves backward together with the slider 20, as shown in Figure 4, against the biasing force of the biasing mechanism 12.
[0078] In addition, along with this backward movement, the trainee pulls both upper limbs toward his / her torso as shown in FIG. 4, bending the elbows, and moving both grips 32 of the swing lever 31 backward.
[0079] The rearward movement of the tip of the rocking lever 31 is transmitted to the sliding part 20 by the transmission part 30a. The trainee uses the muscle strength of both upper limbs to rock the rocking lever 31 rearward against the biasing force of the biasing mechanism 12 and bends the elbows. Therefore, comprehensive training including the upper and lower limbs can be performed while sitting in the wheelchair 2. During training, the trainee may train only the lower limbs by bending and straightening both lower limbs without gripping both grips 32 of the rocking lever 31, or may train only the upper limbs by gripping both grips 32 of the rocking lever 31 and bending and straightening the elbows, without putting force into both lower limbs, from the position shown in FIG. 3 to the position shown in FIG. 4.
[0080] As a result of the above, there is no need to transfer from the wheelchair 2, reducing the risk of accidents during transfer. Furthermore, since the wheelchair 2 is used, trainees can remain seated on the seat of the box-shaped wheelchair 2 with armrests, allowing even trainees with severe symptoms to maintain a stable posture during training. Furthermore, unlike the prior art (Patent Document 1), the entire sliding section 20 to which the wheelchair 2 is connected moves in response to the trainee's operation, giving the trainee the feeling that they are exercising using their entire body, allowing them to train for a long time without getting bored.
[0081] [Training movement 2] Next, the training operation of the training device 1 of the present invention will be described with reference to the flow chart of FIG.
[0082] Fig. 8 is a flow diagram of the present invention during training. Fig. 7 shows the display screen 80a (display unit 714) of the dedicated application of the user terminal 41 during training.
[0083] First, the switch 706 of the transmitting unit 300 in the terminal unit 50 is turned on (S1), and then the switch (not shown) of the receiving unit 400 in the user terminal 41 is turned on, which establishes a pairing connection via Bluetooth (registered trademark), and when the connection is complete, the word "connect" is displayed on the display screen of the user terminal 41. Next, when the dedicated app in the user terminal 41 is started, the display screen 80a shown in Fig. 7 appears as the initial screen.
[0084] Next, on the display screen 80a, input of initial settings is accepted based on the operation of the user who is a trainee or an assistant such as a therapist (S2 to S5 in FIG. 8).
[0085] First, the training time is set (S2). The time is set by directly inputting it into the input box 82a on the display screen 80a or by tracing the pointer 81a with a finger. The training time refers to the total time of training, and the remaining time relative to the preset total time is displayed.
[0086] Next, the target number of repetitions is set (S3). The target number of repetitions is set by directly inputting the number of repetitions into the input frame 82b on the display screen 80a or by tracing the pointer 81b with a finger. The target number of repetitions refers to the number of times that the sliding portion 20 moves back and forth from the posture of FIG. 3 to the posture of FIG. 4 during training, with one repetition being the number of times the sliding portion 20 moves back and forth.
[0087] Next, the set distance is set (S4). The set distance is set by directly inputting the value into the input frame 82c on the display screen 80a or by tracing the pointer 81c with a finger. The set distance is the distance that the sliding portion 20 moves from the footrest 11 (reference position).
[0088] Next, the time for the exercise cycle is set (S5). The time is input and set by directly inputting into the input frame 82d on the display screen 80a or by tracing the pointer 81d with a finger. Note that an exercise cycle is the number of times that the sliding portion 20 moves back and forth from the posture of FIG. 3 to the posture of FIG. 4 during training. In S5, the target value for the time required for one exercise cycle is set. After setting, the input contents are confirmed by pressing the "Initialize / Set" button shown at 83b in FIG. 7.
[0089] Next, the "Start" button is pressed (S6). Training begins by pressing the "Start / Stop" button 83c shown in 80a of FIG.
[0090] Next, after training, the training results are displayed (S7). By pressing the "Start / Stop" button 83c shown in 80a of FIG. 7 again, the training ends and the training results are displayed (not shown). The training results include the training time, number of times, goal achievement rate, rank, etc. The rank displays how well the training matched the set distance. Alternatively, when the set time reaches 0, the training ends and the training results are displayed.
[0091] Next, the operation during training will be described in more detail. The dedicated application in the user terminal 41 has the following two features (1) and (2) during training. (1) The dedicated app controls the music to continue playing normally if the slider 20 is moved back and forth to any song selected by the trainee within the set exercise cycle time, otherwise the music will stop halfway through.
[0092] (2) The dedicated app is configured to visually train the trainee while changing the display position of a person or anthropomorphic character in the virtual space according to the distance measured by the distance sensor 16. A person character 90a sitting in a wheelchair is displayed in the virtual space shown on the display screen 80a in FIG. 7, and the display position is changed left and right according to the distance measured by the distance sensor 16. When the set distance is met, the tip 90c of the front wheel of the wheelchair reaches a position where it overlaps with the target line 90b, and the number of times is incremented. The dedicated app is not limited to the above configuration. It may also be configured to slow down the movement speed of the person or anthropomorphic character in the virtual space according to the measured movement cycle, or it may be configured so that the person or anthropomorphic character in the virtual space is fixed in a fixed position while the background moves in a flowing manner according to the measured movement cycle.
[0093] As a result of the above, it is possible to break up the monotony of exercise and provide training that is fun and not boring.
[0094] [Second embodiment]
[0095] Next, a second embodiment of the present invention will be described with reference to the accompanying drawings. Regarding the second embodiment described below, differences from the first embodiment will be described. Explanations of parts common to the first embodiment will be omitted and the same reference numerals will be used.
[0096] (Overall configuration of the second embodiment) Fig. 9 is a perspective view showing an example of the overall external configuration of a training device 1A. In training device 1, a simple stationary chair is detachably connected to main frame 10 instead of the above-mentioned wheelchair 2, and a trainee with mild symptoms can train while sitting in chair 60. In Fig. 9, training device 1 comprises main frame 10, footrest 11, slide section 20, chair connecting section 100, swing lever 31, and terminal unit 50. By adding chair connecting section 100 (described later) to training device 1 connected to the above-mentioned wheelchair 2, the wheelchair 2 and chair 60 can be selectively interchangeable while using the same training device 1.
[0097] According to this, even a trainee with mild symptoms who cannot use a wheelchair 2 can easily train by using the chair 60.
[0098] The training device 1, which is used by detachably connecting a chair 60, comprises a main frame 10, a footrest 11 which is attached integrally to the front of the main frame 10 and which secures the feet of a trainee who sits on the chair 60 to train, a slide 20 which serves as a slide mechanism attached to the main frame 10 and is capable of sliding back and forth relative to the footrest 11, and a chair connecting part 100 which is attached to the slide 20 and connects the chair 60 with the entire chair 60 resting on the slide 20, so that a trainee can train while sitting in the chair 60.
[0099] This allows the chair 60 to be easily connected to the training device 1.
[0100] 14, the chair connecting part 100 comprises a slide guide 102 fixed integrally to the slide part 20 so as to extend in one direction, and a slide block 101 slidably supported on the slide guide 102, and is configured so that the legs 62 of the chair 60 are fixed to the slide block 101 with thumb screws 65 and connected so as to be slidable along the slide guide 102. Two sets of slide guides 102 and slide blocks 101 are arranged on the slide part 20 so as to be connectable to the legs 62.
[0101] As shown in FIG. 9 , the slide mechanism position adjustment unit 68 as a chair position adjustment unit is a mechanism for adjusting the front-to-rear position of the chair 60 on the main body frame 10, and is provided with a restriction pin 684 as a positioning member for positioning the chair 60 at a predetermined position on the slide unit 20. Specifically, the leg 62 of the chair 60 is provided with the restriction pin 684 as a positioning member for positioning the leg 62 at any position within the sliding range, and the positioning member positions the leg 62 relative to the slide guide 102 by moving the restriction pin 684, which is provided on the leg 62 so as to be able to move forward and backward, into one of a plurality of insertion holes 103 formed on the slide guide 102. Note that a support part 682 that supports an operating lever 681 is formed integrally with the leg 62 of the chair 60, and the operating lever 681 is fitted to the support part 682 so as to be able to rotate about a rotation center 685, and an arm 685 having the restriction pin 684 at its tip is fixed to the operating lever 681. When the caregiver moves the operating lever 681 up and down, the restriction pin 684 can be freely moved forward and backward relative to the insertion hole 103 of the slide guide 102.
[0102] This allows the front-to-back position of the chair 60 to be adjusted to suit the trainee's body shape. Also, the chair 60 does not shift forward or backward during training, ensuring safety.
[0103] As shown in Figure 15, the locking means 64 is a means for locking the chair 60, which is rotatably installed relative to the main frame 10, so that the chair 60 does not rotate relative to the main frame 10. The locking means 64 can lock the rotation position of the chair 60 at least in the front and left and right lateral positions. Specifically, the leg supports 63, which fit the seat 61 and legs 62 of the chair 60, are made up of a lower support 632 attached to the legs 62 and an upper support 631 to which the seat 61 is attached, which is fitted from above onto the inner periphery of the lower support 632 so as to be rotatable up and down. At the fitting portion between the lower support 632 and the upper support 631, a locking means 64 is provided, which consists of a plurality of through-holes 633 formed in the upper support 631 and a spring knob 641, in order to lock the seat 61 at a predetermined rotation angle.
[0104] This prevents the chair 60 from shifting in the rotational direction during training, ensuring safety. Also, the trainee can get on and off the training device 1 easily and safely.
[0105] The chair 60 further includes a pair of armrests 67 that are arranged on both sides of the seat 61 in the left-right direction and that support the trainee's forearms.
[0106] This allows the trainee's forearm to be supported safely during training.
[0107] The chair 60 also has a backrest 66 that can support the upper body of the trainee, and a handle 69 that is attached to the rear surface of the backrest 66.
[0108] This is convenient because the caregiver can adjust the position of the chair by holding the handle 69 from behind.
[0109] The chair 60 is also provided with a safety belt 105 that is arranged on the chair 60 and prevents the trainee from slipping off the chair 60. Specifically, a lock detection mechanism is provided on the buckle side of the safety belt 105, and when an insert piece (not shown) of the safety belt 105 is inserted into the buckle to lock it, the lock detection mechanism detects the locked state of the safety belt using a switch or the like.
[0110] This ensures safety during training and when the trainee gets on and off the training device 1. In addition, since a safety belt detection mechanism for detecting the state of the safety belt 105 is provided, it can detect whether the safety belt 105 is fastened or not and issue an alarm.
[0111] (Training movement of the second embodiment) Next, a method of using the training device 1 in the second embodiment will be described.
[0112] When using the training device 1, first, as shown in Fig. 10, the chair 60 is connected to the sliding section 20 with the entire chair 60 riding on the sliding section 20. Details of the connection method have been described above, so a detailed explanation will be omitted here. Also, in the explanatory diagrams of the training operations in Figs. 10 to 13, the slide mechanism position adjustment section 68 has been omitted for the sake of simplicity.
[0113] Next, using the slide mechanism position adjustment unit 68 described above, the front-to-rear position of the chair 60 on the main body frame 10 is lowered all the way to the rear and positioned by the positioning member 684. At this time, the seat 61 is locked in its rotation position, for example, to the left side, on the main body of the leg unit 62 by the locking means 64. Then, in this state, the trainee 3 gets on and sits in the chair 60, and fastens the safety belt 105 to prevent the trainee 3 from slipping off the chair 60. The safety belt 105 is equipped with a safety belt detection mechanism for detecting the fastening state of the safety belt 105, and is configured to, for example, display a warning until the safety belt 105 is fastened.
[0114] Next, as shown in FIG. 11, the caregiver releases the locking means 64, operates the handle 69 attached to the underside of the backrest 66 of the chair 60, rotates the chair 60 so that the trainee 3 faces forward, and locks the rotated position with the locking means 64.
[0115] Next, as shown in Figure 12, the slide mechanism position adjustment part 68 is used to raise the front-to-back position of the chair 60 on the main frame 10 to the forward training position, and the positioning is performed by the positioning member 684. Also, on the front side of the main frame 10, there is provided a footrest 11 that is integral with the main frame 10 and that secures the feet of the trainee who is a wheelchair user, and the footrest 11 has a retaining belt 14 arranged on each side of the foot, and both feet are secured to the footrest 11 by the retaining belts 14. Then, both grips 32 at the tip of the swing lever 31 are grasped with both hands.
[0116] The initial posture of the trainee 3 is as shown in Figure 12, with both lower limbs bent and both upper limbs stretched forward, grasping both grips 32 of the swing lever 31. At this time, the swing lever 31 is approximately perpendicular to the ground.
[0117] Next, when the trainee extends both lower limbs from the posture shown in FIG. 12 and pushes the entire body backward using the muscular strength of both lower limbs, the chair 60 moves backward together with the slider 20, as shown in FIG. 13, against the biasing force of the biasing mechanism 12.
[0118] In addition, along with this backward movement, the trainee 3 draws both upper limbs toward his / her body as shown in FIG. 13, bending the elbows, and drawing both grips 32 of the swing lever 31 toward his / her body.
[0119] Thereafter, training is performed by repeating the operations shown in FIGS.
[0120] Furthermore, when the patient 3 finishes training and gets off the training device 1, first, as shown in Figure 11, the slide mechanism position adjustment part 68 is used to lower the front-to-rear position of the chair 60 on the main frame 10 all the way to the rear, and then the positioning member 684 is used to position it.
[0121] 10, the seat 61 is locked in its rotation position, for example, at the left side position on the main body of the leg 62 by the locking means 64. In this state, the patient 3 gets off the training apparatus 1.
[0122] The rocking lever 31 has a transmission unit 30a, which transmits the operating force of the rocking lever 31 to the sliding unit 20 as a driving force counter to the biasing force of the biasing mechanism 12. Therefore, combined training of the upper and lower limbs can be performed while sitting on the chair 60. During training, the user may train only the lower limbs by bending and straightening both lower limbs without gripping both grips 32 of the rocking lever 31, or may train only the upper limbs by gripping both grips 32 of the rocking lever 31 and bending and straightening the elbows, without applying force to both lower limbs, from the posture of FIG. 12 to the posture of FIG. 13.
[0123] As described above, even trainees with mild symptoms who do not use wheelchairs can easily train by using a chair. Also, because the entire body (entire chair) moves in response to the trainee's operation, the trainee feels as if they are exercising using their entire body, allowing them to train for a long time without getting bored.
[0124] It is clear that the present invention is not limited to the present embodiment, and that within the scope of the technical concept of the present invention, the present embodiment may be modified as appropriate in addition to the modifications suggested in the present embodiment. Furthermore, the number, position, shape, etc. of the components are not limited to the present embodiment, and the number, position, shape, etc. of the components may be any number, position, shape, etc. suitable for implementing the present invention.
