A pair of left and right footrests that reciprocate back and forth alternately, a handrail section supported at a predetermined height in front of the footrests, and the footrests are driven back and forth to reciprocate. A walking training device comprising a base portion having a mechanism for moving the rear portion up and down within a predetermined angle.

More specifically, as described in claim 2, the front of the footrest is rotatably supported by a base plate via a shaft, and the lower surface of the rear part is supported by the base plate. The base plate is movably engaged with a roller having a predetermined length, and the rail is fixed to the base portion. A walking training device according to claim 1 is configured.

According to a third aspect of the present invention, a nut block is fixed to the base plate, a ball screw is engaged with the nut block, and the ball screw can be rotated forward and reverse by a servo-controlled motor. The walking training device according to claim 2 is configured.

Further, according to a fourth aspect of the present invention, there is provided a walking training apparatus according to the second or third aspect, wherein the arm reciprocates within a predetermined angle range by a servo-controlled motor. .

Therefore, according to this walking training device,
Restoring the walking function, which is reduced by imposing a passive exercise on a walking trainer, enables walking training without the need for a caregiver.
Efficient rehabilitation can be performed with caregiver-free economy, and training safety is ensured.

A substantially U-shaped support is provided horizontally on the upper part of each of the trainers 3 and 14, and the trainer 6
Are located at a predetermined height on the front part and on both the left and right sides, and preferably the height and the front and rear can be adjusted. If the supporter 12 is directly supported by the belt 11, the trainer holder 4
May not be required.

The footrest 7 and the base 8 will be described in detail. The base part 8 is connected to the auxiliary frames 1d and 1f of the frame 1 in a pair on the left and right sides of the foot of the trainee 6 and is disposed in parallel between the bottom frame 1a and the auxiliary frame 1e, respectively, as shown in FIG. And rails 1 on the left and right side walls of the channel member 20.
9 and 19, the front and rear portions of the channel member 20 are closed by the front plate 21 and the rear plate 22, respectively, and the front and rear portions of the ball screw 23 are positioned substantially on the center line of the channel member 20.
At 4 and 24, the servo motor 25 (see FIG. 5) is supported on the front plate 21 side so as to be rotatable around the axis, and the end of the ball screw 23 is connected to this. A pair of sliders 26, 26 are respectively engaged with the rails 19, 19 so as to be slidable back and forth.

A table 27 is mounted and fixed on the sliders 26, 26, and a nut block 28 is fixed on the lower surface of the table 27.
The ball screw 23 is engaged with and penetrates the screw hole 8. Therefore, when the servo motor 25 is driven to rotate, the ball screw 23 rotates, and the nut block 28 reciprocates in the front-back direction along the ball screw 23, so that the table 27 can move back and forth.

As shown in FIGS. 4 and 6, a cover plate 29 connecting the front plate 21 and the rear plate 22 to the table 27 is loosely fitted in an upper groove having a substantially horizontal H-shaped cross section. I have.
Therefore, both left and right sides of the table 27 protrude from the cover plate 29 and are on the upper surface than the cover plate 29, and both sides of the rectangular base plate 30 are placed and fixed on both sides thereof. The footrest 7 is swingably supported by the shaft 32 through the shaft. The footrest 7 is a U-shaped groove-shaped footrest having a length enough to accommodate one foot, and has a front part closed.

A stopper 33 is fixed to the base plate 30 so as to be able to come into contact with a substantially central portion of the footrest 7. Rollers 34 abutting on the lower surface of the rear end of the footrest 7 are supported by arms 35, 35 so as to be able to swing up and down, and the arms 35, 35 are provided by a speed reducer 37 of a servomotor 36 fixed to the base plate 30. It is connected to an output shaft 38. Preferably, a belt is provided on the footrest 7 so that the foot F of the trainee 6 can be fastened and fixed by the belt.

The arms 35, 35 can reciprocate only vertically within a predetermined angle range by servo control, and two limit switches 40, 41 are fixed to the side surface of the speed reduction unit case 37 as a fail safe. Therefore, when the servomotor 36 is driven to rotate, the arms 35, 35 move up and down within a certain angle range, and the roller 34 pushes up the rear end of the footrest 7, and reaches the upper limit to lower the rear end. The footrest 7 can move up and down around the shaft 32.

As shown in FIG. 7, a cable for sending a power supply and a control signal to the servomotor 36 is connected via a cable holder 39 which is flexible and deforms while maintaining a U-shape. 2 is connected to the base plate 30 and the other end is connected to the front plate 21 side. As shown in FIG.
Are connected by a cable L. On the screen of the personal computer P, a movement curve capable of adjusting the drive of the servomotor 36 in accordance with the trainee 6 is displayed.

Therefore, the trainee 6 inserts both legs into the holes 12a, 12a of the supporter 12 by the care of a caregiver or the like and is suspended from the trainer holder 4, and the trainer 6 has both footrests 7,
7, one foot F is placed on each of them, and is appropriately fixed with a belt. The handrail unit 5 or the tubular body 10.10 is gripped with both hands to prepare for walking. After the operator signals the trainee 6, the servomotor 25, When the driver 36 is driven, the footrest 7,
7 alternately reciprocate back and forth, and
The rear part moves up and down at a predetermined angle around the axis, that is, the heel part of the foot moves up and down to form a walking state, and the trainee 6 may move his body according to the movement. When the trainee 6 stops walking practice due to an emergency, the operation switch 9 is operated.

The walking training conditions and settings are all performed via a personal computer, and are represented by X (front and rear) and Y (vertical) coordinates displayed on the personal computer screen as shown in FIG. ＮN4 (actually, up to 24 points can be set), and the curve connecting the anode points becomes the locus of the trainee's heel. These coordinates are set independently and can be controlled.
The anode point can be freely set on the XY coordinates. The operator appropriately adjusts according to the physical condition of the trainee 6 and moves the change point of the curve up and down on the screen, thereby moving the leg rests 7, 7 back and forth, and moving up and down the rear, and training. The acceleration and other operations from the beginning to the end in time are coordinated and formed. Thus, the walking trainee does not need the support of the caregiver, and can walk independently for a predetermined time.

[0021]

According to the present invention described above, since it is a device capable of practicing walking alone without the need of support of a caregiver, it is most suitable for rehabilitation of a caregiver shortage, and furthermore, it is possible to improve the safety of walking trainers. Efficient rehabilitation can be performed with care-free economy.
