Or repeating the walking motion. In this case, since it is a single walking surface, the vertical angle with respect to the traveling direction can be adjusted,
Although the walking speed can be adjusted by controlling the motor drive, the speed, height, and angle of the left and right walking surfaces cannot be independently adjusted in consideration of the left and right feet.

Therefore, the conventional walking training device has the following disadvantages. 1. It is dangerous for a person with different lengths of right and left legs to lean left and right when walking. 2. It is dangerous that the speed is too fast or too slow depending on whether the affected side or the healthy foot supports the foot. 3. For patients who show symptoms of adduction and abduction, the weight of the entire sole of the foot cannot be supported, and the patient is supported on the side of the thumb or little finger, causing pain or damage to the tread. 4. A person who cannot kick straight back in the direction of travel is performing a walking motion while sliding his / her foot on the walking surface in the left-right direction, so that the tread is damaged. Alternatively, when the foot does not slip, the walking motion is performed while swinging the upper body to the left and right, and the walking posture is not stable, which is dangerous. 5. There is no straightening function for inner thighs, outer thighs, and crotch.

The inventor of the present invention filed a patent application (hereinafter abbreviated as a prior application) for a "gait training and correction device" in Japanese Patent Application No. 8-265707.・ A straightening device was proposed. In the prior application, the above-mentioned problems were improved, and the following problems were solved. 1. Even for people with different lengths of left and right legs, the ability to walk while standing upright without the body leaning left and right when walking. 2. The ability to set the appropriate resistance and speed for walking on either the affected side's foot or a healthy foot, allowing for smooth and safe walking. 3. The ability to support the weight of the entire sole of the foot, even for patients with adduction and abduction symptoms. 4. Even if you cannot kick straight back in the direction of travel, you should be able to perform a stable walking motion without sliding your feet left and right on the walking surface and without increasing the sideways movement of the upper body . 5. It has a function to correct the inner crotch, outer crotch, and crotch.

[0005] However, in the embodiment of the prior application, since the left-right rotation support shaft is set at the lower part of the roller, there is no need to provide a support frame before and after the walking belt, and between the belt and the support frame. It was safe without pinching the toes, but on the other hand, the walking surface was slid left and right due to the left and right rotation. Needed. In addition, for the forward and backward tilt mechanism, forward rise, rear rise, parallel movement, etc.
Although it had considerable flexibility, it was very functional, but the structure was complicated and the number of parts and weight increased. In addition, a gap is formed at the step between the left and right walking surfaces, and there is a possibility that the toes may be pinched.
Further, when adjusting the angle in front, rear, left and right, a screw operation has to be performed, which is a burden on the operator.

The left and right walking surfaces 1 and 6 are formed by stretching 9. The rear roller 33 is connected by a rotating belt 34 to a motor 35 provided independently on the left and right of the rear of the apparatus. By controlling the rotation of the motor 35, the walking surface speed is changed.
For this purpose, a control device is provided, but is not shown. In FIG. 1, the left walking surface 1 is illustrated with the belt 19 removed and the swash plate 17 and the front and rear rollers 18 and 33 are visible. A left walking surface support shaft front 3 and a left walking surface support shaft rear 4 are arranged on the center line of the left walking surface 1 in the front-rear direction,
The walking surface rotates left and right around this axis. Similarly, a right walking surface support shaft front 8 and a right walking surface support shaft rear 9 are disposed before and after the right walking surface 6.

As shown in FIG. 2, the front 8 (3) of the walking surface support shaft and the rear 9 (4) of the walking surface support shaft are arranged on the same plane as the rotation center of the front roller 18 and the walking surface. ing. Note that the outer shape is partially cut away to show the front and rear 8, 9 of the right walking surface support shaft.

Therefore, as shown in the explanatory view of the right-left tilt rotation mechanism of the walking surface in FIG. 3, when the minimum gap A that does not interfere with the left-right rotation of the left and right walking surfaces 1, 6 is set, , The maximum clearance B when the right walking surfaces 1, 6 are inclined in a mountain shape
Can be minimized. As a result, the minimum gap is maintained without any gap adjustment, which is effective in preventing the foot or the like from being pinched. In order to show the right middle frame rear fulcrum 14 and the lower frame rear 21, a part of the outer shape is broken.

Next, the vertical swing rotation of the right intermediate frame 10 will be described with reference to the right side view of the apparatus of the present invention shown in FIG. The right walking surface support frame 7 is broken so that the inner belt 19 and the front roller 18 can be seen. Bearing portions at the front and rear of the right walking surface supporting shaft of the right walking surface 6 rotating left and right, and at the rear 8, 9 are fixed to the right intermediate frame 10. A rear portion of the right intermediate frame 10 is rotatably supported by a rear support 21 of the right intermediate frame at a rear portion 21 of the lower frame. The details are shown in FIG. 3, which is an enlarged view of the lower left of FIG.

On the other hand, in the front part of the right intermediate frame 10,
An upper and lower screw bracket 24 is rotatably supported at a bracket fulcrum 25. Upper and lower female screws 23 are rotatably mounted on the upper and lower screw brackets 24, and the upper and lower screws 22 are screwed together. The lower ends of the upper and lower screws 22 are rotatably supported on the lower frame front 20 at upper and lower screw fulcrums 26 so as to be rotatable in the front-rear direction. The details are shown in FIG. 4, which is an enlarged view of the lower right of FIG.

FIG. 4 is a view of the right side surface shown in FIG. 2 as viewed from the front, showing a vertical movement mechanism for tilting the right walking surface 6 back and forth. Bracket fulcrum 25, 25 on right middle frame 10
The upper and lower screw brackets 24 are rotatably supported in the left-right direction through the shaft. The vertical screw bracket 24 is mounted with the walking surface vertical tilt motor 12, and rotates the vertical female screw drive gear 29 around the vertical screw 22 via the vertical drive gear 27 and the intermediate gear 28. The upper / lower internal screw drive gear 29 is integral with the upper / lower internal screw 23 and moves up and down by rotating around the upper and lower screws 22 supported by the lower frame front 20.
Therefore, when the walking surface vertical tilt motor 12 is rotated, the front of the right intermediate frame 10 moves up and down together with the vertical screw bracket 24, and swings and rotates around the rear fulcrum 14 of the right intermediate frame to adjust the vertical tilt. Will be

Similarly, the front-back inclination is adjusted for the left walking surface 1. Therefore, since the left walking surface 1 and the right walking surface 6 can be adjusted by rotating the rear fulcrum by one point, the structure is simple, and the number of parts is reduced and the weight is reduced.

As shown in FIGS. 1 and 2, a partition plate 30 is provided between the left walking surface 1 and the right walking surface 6. The partition plate 30 is erected from the lower frame and is continuously installed from the rear part to the front part of the walking surface, corresponding to the front, rear, left and right inclination of the walking surface, and in any case, projects upward from the left and right walking surface. doing. Therefore, at any of the front, rear, left and right inclination positions of the left and right walking surfaces, a dangerous step between the left and right walking surfaces and the intrusion of the toe into the gap are prevented, and at the same time, the crossing of the walking legs is prevented.

Further, as shown in FIGS. 1 and 3, the right and left inclination of the left and right walking surfaces is adjusted by the left and right driving belts 15 by the left and right drive belts 15 via the worm case 16 by the walking surface left and right inclination motors 11. This is performed by driving the front surface support shafts 3 and 8.
The drive from the worm case 16 via the left and right drive belts 15 is due to a problem in assembly adjustment.In terms of structure, the output shaft (worm wheel shaft) of the worm case 16
The front walking shaft support shafts 3, 8 may be directly connected.

In FIG. 4, as described above,
The vertical movement for adjusting the front and rear angles of the left and right walking surfaces is performed by a walking surface vertical tilt motor 12.

Therefore, the front, rear, left and right angles of the left and right walking surfaces can be easily adjusted individually by the motor, so that the optimum position can be easily set, and effective walking training can be performed.

Further, the walking speed of the left and right walking surfaces and the front, rear, left and right angles can be adjusted by operating the operation panel as shown in FIGS. 2, 5 and 6.
