Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a walking/running training device used for walking training of patients in hospitals, etc., and running training in health promotion centers, sports centers, etc. be.

[Prior Art] In conventional walking/running training devices, the movable surface always runs at a fixed speed, or the speed changes according to a pre-programmed sequence, and the speed changes according to the trainee's will during training. In order to change the speed, it was necessary for the trainee to readjust the speed setting while running on the training device or once off the training device.

[Problems to be Solved by the Invention] The conventional walking/running training device described above is configured as described above, so that the movable surface can run at a constant speed regardless of the fatigue or mental state of the trainee. do.

Human walking and running constantly fluctuate depending on the person's mental state and information received from the eyes and ears, and maintaining a constant speed is a huge burden, both physically and mentally. It's easy to get tired.

Therefore, if training is performed for a long time using a conventional walking/running training device that runs at a constant speed, trainees will become extremely fatigued both physically and mentally, and will avoid such training. This had the problem of causing the opposite effect.

In addition, since the movable surface of the 1-meter training device runs at a constant speed, when the trainee becomes tired, he or she slows down in walking and running, and begins to position himself behind the movable surface, making it difficult for him to move faster. You must either return to the center by moving, or operate the operating section of the training device while driving to slow down the speed of the movable surface.

If these cannot be done, the trainee will be thrown backwards from the movable surface, which is extremely dangerous.

Furthermore, during long driving training, it is necessary to change the speed at any time according to the trainee's physical condition and goals.
Conventional walking/running training devices have a problem in that it is extremely difficult for trainees to freely change their running speed.

This invention was made to solve this problem, and the trainee can easily reach the desired running speed by simply trying to run at the desired speed without any other conscious operation. The aim is to provide a walking/running training device that allows for fun and safe training.

[Means for Solving the Problems] The walking/running training device according to the present invention includes a position detecting means for detecting the position of the trainee on the movable surface of the device, and a position detecting means for detecting the position of the trainee on the movable surface of the device. A speed control means for controlling the speed of the movable surface according to information is provided.

[Function] In the walking/running training device of the present invention, the position of the trainee on the movable surface of the device is detected by the position detection means, and the speed control means controls the running speed of the movable surface based on the position information. Therefore, the traveling speed of the movable surface can be changed simply by the trainee changing the position by slightly speeding up or slowing down the speed.

[Embodiment] FIG. 1 is a diagram showing the configuration of a walking/running training device that is an embodiment of the present invention. In the figure, l is a movable surface of an endless belt made of rubber or the like, 2 is a flat low-friction member whose surface is treated with Teflon, 3 is a support frame, and 4
5 is a distance measuring device that is a position detection means using ultrasonic waves, infrared rays, or lasers; 5 is a servo motor that drives the movable surface l in the direction of the arrow in the figure; 6 is a start button that starts the servo motor 5; and 7 is a movable surface. A display section 1 displays running speed, distance traveled, etc., a display section 8 starts the servo motor 5 by pressing the start button 6, and controls the rotational speed of the servo motor 5 according to the position information of the distance measuring device 4; Movable surface l
a control unit that displays on a display unit 7 the running speed and distance traveled after pressing the start button 6; 9 is a trainee; 1;
0 is the end of the movable surface l, and the servo motor 5. A cover that covers the control unit 8, and a distance measuring device 4 on the top. It is equipped with a start button 6 and a display section 7.

Next, the operation of the walking/running training device shown in FIG. 1, which is an embodiment of the present invention, will be explained.

When the trainee 9 steps on the movable surface l and presses the start button 6 with his or her finger, the control unit 8 rotates the servo motor 5 at a low speed, and the movable surface l moves at a low speed in the direction of the arrow in the figure. start. When the trainee 9 wants to increase the speed of the movable surface 1, the trainee 9 increases his or her own walking or running speed so that the trainee 9 comes out in front of the movable surface 1 (position B shown in the figure by a dotted line). do.

Then, the distance measuring device 4 sends information indicating that the distance is short to the control unit 8. When the control unit 8 receives short-distance information manually, it controls the rotational speed of the servo motor 5 to increase, so that the rotational speed increases and the traveling speed of the movable surface 1 increases. When the trainee 9 is located at the center (position A shown in the drawing), there is no change in speed and the movable surface 1 maintains the current speed forever. If it is desired to reduce the running speed of the movable surface l, if the trainee 9 lowers the running speed, the position will naturally retreat to the rear (position C tiF shown by the dotted line). Therefore, the distance measuring device 4 sends long distance information to the control unit 8, and the control unit 8 controls the servo motor 5 to decelerate, thereby decelerating the traveling speed of the movable surface 1.

As described above, the traveling speed of the movable surface l is controlled, so when the trainee 9 increases the speed of walking or running, the position of the trainee 9 moves forward, the traveling speed of the movable surface l increases, and the trainee 9 increases the walking or running speed. When the trainee 9 lowers his/her own speed, his/her position retreats to the rear and the traveling speed of the moving surface l decreases, and if the trainee 9 is within a certain range in the center, = sl The traveling speed of the moving surface l changes. do not.

In this case, the rate of change (acceleration) of the velocity of the movable surface l is not only linearly proportional to the distance between the trainee 9 and the distance measuring device 4, but also increases as the trainee 9 moves further away from the center. Using known techniques, it is easy to set the rate of change as follows, or to set the rate of change in advance to suit the elderly, adults, or athletes.

Furthermore, it goes without saying that the distance measuring device 4 is not limited to being provided in front of the movable surface l, but may be provided at the rear.

FIG. 2 is a plan view showing a walking/running training device according to another embodiment of the present invention, in which the same parts as in FIG. 1 are designated by the same reference numerals. In the figure, 11 is a frame (handrail) provided on both sides of the movable surface l at a height between the waist and chest of the trainee 9, and 12a to 12b are embedded inside one frame 11 at approximately equal intervals. The light emitters 13a to 13h are composed of light emitting diodes and condensing lenses, and the light receivers 13a to 13h are composed of condensing lenses and light receiving elements embedded inside the other frame 11 at positions facing the light emitters 12a to 12h. For example, a pair of photoelectric switches is formed by the light emitter 12a and the light receiver 13a facing each other.

The trainee 9 uses the light emitters 12a to 12h and the light receiver 13a.
-13h and the light is blocked, the state of the light-blocked light receivers 13a-13h changes and the position of the trainee 9 can be detected.

When the light receiver 13a located at the forefront is blocked, the traveling speed of the movable surface l is increased at the largest acceleration rate,
When the light receiver 13c near the center is shielded from light, the speed is increased at a small speed increase rate. If the rearmost receiver 13h is blocked, it will be decelerated at the largest deceleration rate, and the receiver 13h closest to the center will be decelerated.
When f is shielded from light, the speed is decelerated at a small deceleration rate. Also,
Control is such that when the central light receivers 13d and 13e are shielded from light, the traveling speed of the movable surface 1 does not change.

The light emitters 12a to 12h and the light receivers 13a to 13b
It goes without saying that the number is not limited to eight, and can be increased or decreased as necessary.

Furthermore, an ultrasonic switch may be used in which the light emitters 12 a - 12 h are replaced with ultrasonic generators and the light receivers 13 a - 13 h are replaced with ultrasound microphones, and the same operation as above can be performed. is clear.

FIG. 3 is a plan view showing a walking/running training device according to still another embodiment of the present invention, in which the same parts as in FIGS. 1 and 2 are designated by the same reference numerals. In the figure, A, B, and C indicate the center, front, and rear parts when the movable surface l is divided into three parts in the running direction, and 14a controls the detection signal when the trainee 9 enters the front part. An area sensor 14b is configured to send out a detection signal when the trainee 9 enters the rear section C. It is an area sensor similar to 14a that is sent to the control unit 8, and the hatched part is the sensitive range' of the area sensor. In this way, the area sensor 14
a and 14b, it is possible to detect in which part the trainee 9 is present. Therefore, when the trainee 9 is in the center part A, the traveling speed of the movable surface l is not changed, and when the trainee 9 is in the front part B, the speed is increased at a constant rate.
If you are in the rear part C, you should be able to slow down at a certain rate and reach your desired objective. Although the acceleration/deceleration rate in this case is constant, it is also possible to provide an adjustment knob on the control unit 8 and set the desired acceleration/deceleration rate before starting training. Although the control method shown in Figure 3 is simple,
The intended purpose can be sufficiently achieved, and the position detection means,
The advantage is that the control method is simple and the device can be manufactured at low cost.

Area sensors 14a and 14b which are the above position detection means
Instead, the light emission shown in FIG. #12 a and receiver 13
The same operation as described above can be performed by disposing photoelectric switches consisting of a (IN) on each side of the frame.

Furthermore, a wire tension displacement transducer can be used as the position detection means.

This wire tension type displacement transducer has a rotary ring of a potentiometer connected to the center shaft of a drum wrapped around a wire.
This drum is always biased by a mainspring in the direction of winding the wire. When the wire is pulled out against the force of the mainspring and connected to the trainee 9 at the end, the length of the wire fed out changes depending on the position of the trainee 9, and the rotation angle of the drum changes. The position of the trainee 9 can be detected by changing the resistance value of the connected potentiometer.

Further, as the speed control means, in addition to the one using the servo motor 5, one using a motor drive by frequency conversion,
Alternatively, it goes without saying that a method of interposing a mechanical transmission between the drive shaft of the movable surface 1 and the drive motor can be used.

[Effects of the Invention] As explained above, the present invention provides a walking/running training device that uses a position detection means for detecting the position of a trainee on a movable surface and position information obtained by this position detection means. Since the configuration is provided with a speed control means for controlling the traveling speed of the movable surface, the trainee gets on the movable surface and presses the start button to start the movable surface and move the trainee's own position forward or backward. You can change the running speed of the movable surface at will, without any other operations, just by saying, if you want to run fast, go faster, if you want to run slower, go slower.

Therefore, the training can be carried out in accordance with the trainee's will, so that the training can be enjoyable without being forced or excessively burdensome. Furthermore, it is now possible to train with complex and advanced programs that were not possible with conventional equipment, and even if the trainee suddenly becomes tired, the moving surface will naturally slow down to avoid dangerous situations. It has excellent effects such as:
