Abstract

PROBLEM TO BE SOLVED: To always maintain a distance from a visual observation object in a proper range when reading a book or the like, and prevent myopia by arranging a measuring means which is supported in a forehead part of a wearer by a support means and measures a distance from a front object, and actuating an informing means when a measuring distance falls wide of a prescribed range. SOLUTION: When a posture correcting tool 1 is used, first of all, a prescribed range is set so that a distance up to a visual observation object (a book) from an eye becomes 30 to 40 cm being a proper value. Next, a support means 2 on which an opening 2a is formed in a horseshoe shape turning to the occipital side and the opening 2a can be elastically deformed in the expanding/contracting direction, is fitted to and installed in a head part H of a user P. A position is adjusted so that a main body 3 is positioned on the forehead, and a switch 6 is turned on after an angle of a main body 3 is adjusted so that a book enters a visual field of a distance measuring port 5 in a condition of visually observing the book. Then, a distance between the book and the posture correcting tool 1 is measured by a distance measuring means, and when a measuring distance falls wide of a prescribed range, an informing means is actuated, and the user P is informed of a sound and vibration or the like.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a posture correcting device which is mounted on a head and corrects the posture of a wearer during reading or the like.

[0002]

2. Description of the Related Art In recent years, an increase in myopia, particularly among young people, has been concerned. The main reason for this is that the distance between the eye and the visual target is an appropriate distance, especially during reading.
This is for maintaining a posture of less than ４０40 cm for a long time. In order to avoid such a posture, it is common practice for the surrounding person to give oral attention.

[0003]

However, there is a limit to verbal attention and it is impossible to pay attention when no one is around. Becomes worse, and as a result,
There is a problem that the progress of myopia cannot be sufficiently prevented.
In addition, there is also a problem that it is difficult to keep the distance from the eye to the visual target always within an appropriate range, especially for a young person whose distance sensation has not yet been developed.

The present invention has been made in view of the above circumstances, and corrects a posture so that the distance to a visual target is always maintained within an appropriate range even when a young person is reading alone. Its purpose is to prevent the progress of myopia.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a posture correcting tool for correcting the posture of a wearer at the time of reading or the like, and in particular, a support means detachably supported on the head of the wearer;
A distance measuring unit that is supported by the supporting unit at the forehead of the wearer and measures a distance to an object in front of the wearer; and a notifying unit that notifies the wearer that the distance is out of a predetermined range. The feature is that.

In this case, it is desirable that the direction of the distance measuring means is at least vertically variable. More preferably, the predetermined range can be set arbitrarily. On the other hand, the notifying means notifies the wearer that the distance to the object ahead is out of the predetermined range, for example, by sound and / or vibration.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of a posture correcting tool 1 according to the present invention. Reference numeral 2 denotes a supporting means. The supporting means 2 has a horseshoe shape in which an opening 2a is formed in a part, and is elastically deformable in a direction in which the opening 2a is enlarged or reduced.

Reference numeral 3 denotes a main body.
Through the support means 2 on the opposite side (front side) of the opening 2a
, And swingable up and down with the hinge 4 as a fulcrum, as shown by an arrow M in the figure. Also, reference numeral 5
Is a distance measuring port of a distance measuring means (not shown) accommodated in the main body 3, and the distance measuring port 5 is opened on the front surface of the main body 3, and as a result, an object located in front of the main body 3 Among them, it is possible to measure the distance to an object within the field of view of the distance measuring port 5. A known distance sensor using infrared rays, ultrasonic waves, or the like is used as the distance measuring means.

Further, a notifying means (not shown) for notifying the wearer that the distance to the object measured by the distance measuring means is out of a predetermined range is accommodated in the main body 3.
As the notification means, for example, a buzzer and / or a vibrator are used. The predetermined range can be arbitrarily set as long as it is within a range in which the distance measuring means can measure the distance. On the other hand, reference numeral 6 denotes an operation switch of the posture correcting tool 1, and reference numeral 7 denotes a stop switch of the notification unit.

When the posture correcting tool 1 is used, first, the predetermined range is set so that the distance from the eye to the visual target in reading or the like becomes an appropriate value of 30 to 40 cm. As shown, the support means 2 is fitted to the head H of the wearer P with the opening 2a facing the back of the head, and the position of the main body 3 is adjusted so that the main body 3 is positioned on the forehead. Next, as shown in FIG. 2, the angle of the main body 3 is adjusted so that the viewing target 8 is within the field of view of the distance measuring port 5 while the viewing target 8 is actually viewed.

Further, by turning on the switch 6 in this state, the distance L ₁ between the visual object 8 and the posture correcting tool ₁ is measured. As a result, if in the case where the distance L ₁ is out of the predetermined range, the notification means is operated, the distance L ₁ is that out of a predetermined range, and notifies the wearer P by the sound or vibration. By notifying means for visually viewing the object 8 while adjusting the distance L ₁ so as not to operate, the wearer P
Distance L ₂ from the eye to the visual target object 8 is maintained 30~40cm a proper range at all times.

That is, according to the posture correction tool 1, the year
Even if a few people are reading alone, the distance L_TwoAlways
Is maintained within the proper range, and as a result, the posture of the wearer P is
It is corrected to prevent the progress of myopia. Also visually
By changing the direction, etc., the distance L ₁Is the above treatment range intentionally
If you want to remove it, turn on the stop switch 7 and
If the stage is temporarily stopped, the notification means will be activated
There is no.

Further, since the posture correcting tool 1 is extremely lightweight and small, and is easy to operate, the feeling of wearing is small and even a young person can use it alone. In addition, the shape of the posture correcting tool 1 is not limited to the illustrated one,
Can be made into a band-like or hat-like shape, an ear-hook type eyeglass frame shape, or the like. Further, an earphone may be provided in the notification means, and the wearer P may be notified of the operation sound of the notification means via the earphone.

[0014]

As described above, according to the posture correcting device of the present invention, even when a young person is reading alone,
The distance from the wearer's eye to the visual observation object is always maintained within an appropriate range, and as a result, the posture of the wearer is corrected and myopia is prevented from progressing.
