Description

[Detailed description of the invention] The present invention relates to a load display device for a walking training device,
In particular, the present invention relates to a load display device suitable for displaying a varying load as a percentage.

In recent years, when re-educating walking patterns for patients who have been bedridden for long periods of time or patients who have equinus contracture or ataxia due to hemiplegia or cerebral palsy after a stroke, we have begun to use standing posture training and training. 2. Description of the Related Art Gait training devices have come into use that allow trainees to perform weight-bearing training, gait balance training, etc. while visually checking what is displayed on a display device. This type of walking training device usually has a pair of left and right running belts that can repeatedly move back and forth in opposite directions, and a pair of left and right handrails to assist walking. The patient is now able to grasp his/her step length, walking speed, weight balance, etc. by looking at the display on the front display.

Conventional load display devices used to display the balance of body weight, for example, have a configuration in which the pointer on the display panel swings left and right depending on the ratio of the weight applied to the left and right lower limbs, Since the display is not expressed as a percentage, it is difficult to judge when using a light object, especially a child, because the pointer does not move much, and the pointer's deflection may be difficult to read, especially for patients with poor eyesight. There were also drawbacks such as it being difficult for trainees to intuitively determine whether the balance was good or bad.

The present invention eliminates the above-mentioned drawbacks of the conventional technology.In order to display the magnitude of the load measured as the weight of the human body supported by the limbs, the light-emitting area occupied by each display surface is arranged to resemble the shape of the human body. The display panel that displays the load value depending on the size of the load is made to emit light with a light emitting area of a size corresponding to the ratio of the measured load value to the maximum value of the pre-measured load, and the measured load value can be displayed statically as well. It is an object of the present invention to provide a load display device for a walking training device that displays a load in a manner that is dynamic and visually appealing.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Figures 1 and 2 are a perspective view and a side view of an embodiment of the gait training device to which the load display device of the gait training device of the present invention is applied, respectively, and Figure 3 is an embodiment of the load display device of the gait training device described above. An example schematic circuit configuration diagram is shown.

In Figures 1 and 2, the gait training device 1 is particularly suitable for users of prosthetic legs who need to re-educate their gait pattern, patients after surgery for implanted hip and knee prosthesis, patients with hemiplegia, and patients with balance dysfunction. It was developed for the purpose of training patients to recover their walking function, and involves passively moving the left and right legs of patients in the pre-walking stage alternately back and forth, and measuring the distance traveled (step length). It is now possible to restore walking function by changing the walking speed and walking speed.

The trainee first walks around the running belts 3l and 3r, which are provided with handrails 2l and 2r on both sides and which move alternately on the left and right.
stand on the footprint of At the same time, the accompanying doctor or nurse adjusts the stride length and speed according to the trainee's ability using the operation panel 5 above the life-sized flat reflector 4 provided in front of the trainee. Then, when the trainee presses the start/stop push button switches 6 provided on the handrails 2l and 2r, the running belt 3
1 and 3r move forward and backward alternately on the left and right, and the trainee's lower limbs are moved passively. By pressing the push button switch 6 again, the running belts 3l and 3r can be stopped on the spot, and the trainee can move the reflector 4 while standing still.
You can balance the left and right sides while looking at the

In this way, the gait training device 1 does not plantarly flex only the ankle joint, but also uses the left and right running belts 3.
L and 3r alternately move forward and backward, moving the entire lower limbs of the trainee riding on them, so even when weight is being loaded, local strain is not applied.
Since the hip joints work, it is easy to get a feel for walking, and it also has the advantage of being able to dynamically adjust the load balance between the left and right sides.

Next, the load display device 10, which is the main part of the present invention, will be explained with reference to FIG.

In this embodiment, the load display device 10 displays the weight loads applied to the left and right lower limbs and the left and right upper limbs by displaying them on the operation panel 5.
This is visually displayed on the upper display panel 11. For this reason, load cells 12l, 12r and 13l, 13r using semiconductor strain meters, etc. are installed on the left and right handrails 2l, 2r and the running belts 3l, 3r, respectively. 13l,
The weight load measured at 13r is calculated as a ratio by a calculator 14 in the operation panel 5. When the trainee first stands on the running belts 3l, 3r, the calculator 14 calculates the load meters 12l, 12r, 13l, 13r.
The trainee's weight measured by
Calculate as a fraction.

On the other hand, the display panel 11 has a head portion 11a and a body portion 1.
The four limbs 11c other than 1b have a human-shaped display surface that emits light, and in this embodiment, each limb 11c has 40 light emitting diodes 15 arranged vertically.
The light emitting diodes 15 are arranged in rows with 10 light emitting diodes in each row, and a predetermined number of light emitting diodes 15 are turned on in accordance with the output of the arithmetic unit 14.
In this lighting method, each limb 11c is sequentially lit from the lower light emitting diode 15 to the upper light emitting diode 15, and the light emitting diode 15 that has been lit is
The ratio (size) of the light emitting area occupied by each limb 11c
corresponds to the percentage of the load mentioned above.

Therefore, if the trainee on the running belts 3l, 3r can assume a balanced posture with weight equally applied to the left and right lower limbs, the lower limbs 1 of the display panel 11
1c is a state in which half of each area is emitted, strictly speaking
Twenty light emitting diodes 15, half of the 40 light emitting diodes 15, are turned on. Also, if you stand up with a single strike, the lower limb part 11
Only one side of c emits light. Therefore, the trainee can visually and clearly grasp how to apply weight to both lower limbs from the way the display panel 11 is displayed, and in particular, the trainee can clearly and directly grasp his or her balance as determined by the reflector 4. Since the relationship between posture and weight bearing is obvious at a glance, highly effective posture correction training can be administered.

Furthermore, when walking is assisted by placing the upper limbs on the handrails 2l, 2r, the light emitting area of the limbs 11c of the display panel 11 changes depending on the weight applied to the handrails 2l, 2r. When the trainee supports the body only with the upper limbs in positions 2l and 2r, half of the display area corresponding to the upper limbs 11c lights up, allowing the trainee to visually grasp the strength of each limb.

Furthermore, even during walking training by moving the running belts 3l and 3r, the trainee can monitor the body shield as he or she walks from the display panel 11, which can continuously change the light emitting area according to the walking. Because you can easily understand the movement back and forth visually,
Extremely effective for biofeedback training of walking.

In this way, the load display device 10 having the above configuration
Displays the weight of a person on the left and right lower limbs or the left and right upper limbs as the size of the light emitting area on the display panel 11 so that it can be visually grasped at a glance. There are no inconveniences such as the display being difficult to read or the dynamic changes in load being difficult to grasp, unlike conventional load display devices that help you understand how to apply the load.

Furthermore, since the load distribution is expressed as a percentage of the trainee's body weight, all trainees can understand their own exercise patterns under the same conditions, regardless of the size of their body weight.

As explained above, according to the load display device of the walking training device according to the present invention, the light emitting area of the display panel is determined by the ratio of the load value measured by the load cell to the maximum value of the pre-measured load. Because the configuration changes depending on the load, it is possible to visually grasp the load both statically and dynamically as the size of the display panel's light-emitting area, and therefore, regardless of the size of the load, changes in the load can be maintained at the same level. It is suitable for monitoring conditions, etc., and is therefore applicable, for example, to walking training devices that require balance in a standing position, and when measuring the weight applied to the left and right lower limbs and displaying it in a way that directly appeals to the eye. It has excellent effects, such as being effective for both children and adults.

In addition, the load display device of the walking training device according to the present invention uses four load meters, and is configured as a weight display device that displays the weight of a person when supported by the four limbs as the support load of each limb. By arranging the display panel provided corresponding to the load meter to resemble the shape of the human body, effects such as being able to visually grasp the weight balance can be made more effective.
