Description

[Detailed explanation of the invention] Eyeball exercise by moving the line of sight is effective in recovering from eye fatigue, training eyeball muscles, and preventing aging, but until now there was no device suitable for this purpose. .
This invention realizes a device suitable for performing eye movements as described above.

The device of this invention has a dark box with a window provided approximately in the center of the front. When looking into the dark box through this window, the light spot moves, and by gazing at it, the eyeball moves. There are two modes of movement of this light spot: clockwise rotation and counterclockwise rotation. In order to implement these modes, a light guide is provided which pivots about a horizontal axis passing through said window, which light guide emits the light of a light source located on said axis from its pivoting tip. There is. This light guide is driven by an electric motor, and the direction of rotation of the electric motor can be selected by a selection switch.

Next, this invention will be explained based on illustrated embodiments.

This embodiment is configured so that the following light spot movement modes can be obtained.

A Upward and downward B Leftward and rightward C Upper left and lower right D Upper right and lower left E Turning in a clockwise direction F Turning in a counterclockwise direction In Fig. 1, the pillar 2 installed at one end of the stand 1
A dark box 3 is supported on top, and a chair 4 whose height is adjustable is provided at the other end of the stand.

As shown in FIG. 2, a support 5 is erected within the dark box 3, and a bearing 7 for supporting a horizontal hollow rotating shaft 6 is provided in the middle of the support 5. A viewing window 9 is provided on the front wall of the dark box 3 on the extension of the axis 8 of the rotating shaft 6.

The rotating shaft 6 supports the center of a tray-shaped rotary disk 10 made of a milky-white translucent material at its front end, and has a groove wheel 11 and a friction wheel 12 fixed to its rear portion. Reference numeral 13 denotes a light guide, which is composed of a base 13a located within the rotating shaft 6, and a turning section that bends from the base and extends along the back surface of the rotating disk 10, and the end on the base side is exposed to the rear end surface of the rotating shaft 6. However, the end portion on the rotating portion side terminates at the peripheral edge portion 14 of the rotary disk 10.

Reference numeral 15 denotes a reversible electric motor, which is supported by an arm 16 provided on the support column 5 and has a groove wheel 17 attached thereto. Grooving wheel 1
A transmission belt 18 is placed between 7 and 11. A friction wheel 19 is in contact with the friction wheel 12, and is rotatably supported by a horizontal shaft 21 at the end of an arm 20 provided on the support 5, and a colored disk 22 with different colors for each part is fixed to the back side. . A portion of this color disk 22 covers the rear end surface of the light guide 13 .

A miniature light bulb 23 is supported at the tip of an arm 24 provided on the support 5, and faces the rear end surface of the light guide 13 with the color disk 22 in between. 25 is a ring-shaped light bulb support frame,
The upper and lower parts are fixed to the column 5 by fixtures 26 and 27, respectively, so that the axis 8 is the center, and the upper part, the lower part, the left part, the right part, the upper left part, the upper right part, the lower left part, and the right 28 miniature light bulbs each at the bottom
a, 28b, 28c, 28d, 28e, 28f,
28g and 28h, and these miniature bulbs are located behind the peripheral edge 14 of the rotary disk 10.

29 is a ventilation fan installed at the top of dark box 3, 32, 3
3 and 35A to 35F are switches for various operations provided on the front of the dark box 3.

FIG. 3 shows the electric circuit of the above-mentioned device, in which 31 is a power supply terminal, 36 to 42 are relays, and 43 to 45 are timers. Codes indicating relays or timers with letters such as a, b, c, d, etc. indicate the respective contacts, and among the symbols indicating various types of contacts, the small circle is not filled out. indicates a normally open contact, and a filled small circle indicates a normally closed contact. Incidentally, the time limit of the timer 43 defines the entire time for performing the eyeball movement, and the timers 44 and 45 define the lamp switching intervals in the above-mentioned modes A to D. In addition, relay 41
controls the forward rotation circuit of the electric motor 15, and the relay 42 controls the reverse rotation circuit of the electric motor 15.

In the above-mentioned device, the power-on pushbutton switch 32 is pressed and the desired mode, e.g.
When mode selection switch 35A is closed, relay 36 is energized, self-holding contact 36a is closed, and current is supplied to bus bars 46 and 47. Then, timers 43 and 44 start, and at the same time relay 3
9 is energized and its contacts 39a, 39b, 39
c, 39d closes. As a result, the miniature light bulb 2 above
8a lights up.

When the time limit of the timer 44 (approximately 1 to 2 seconds) is reached, the contact 44a closes, the timer 45 is started, and the relay 38 is energized. Then,
Contacts 38a, 38b, and 38d of the relay close and contact 38c opens, completing the self-holding circuit of the relay, energizing relays 37 and 40, and deenergizing relay 39. As a result, the normally closed contact 37a of the relay 37 opens and stops the operation of the timer 44, and the contact 39a of the relay 39 opens and the miniature light bulb 28
A goes out, and instead, the contact 40a of the relay 40 closes and the lower miniature light bulb 28b lights up.

When the time limit of the timer 45 (approximately 1 to 2 seconds) is reached, the contact 45a opens and deenergizes the relay 38, so the contacts 38a to 38d are restored and the relay 38 is turned off.
7 and 40 are deenergized, and relay 39 is energized. As a result, the timer 44 is started again,
The miniature light bulb 28b goes out and the miniature bulb 28a lights up again.

In this way, the miniature light bulbs 28a and 28b alternately flicker at intervals determined by the timers 44 and 45, so if you look into the dark box 3 through the window 9 and look at the light spot, you can immediately switch to A mode. In other words, it is possible to move the eyeballs in the vertical direction.

Next, turn the mode selection switch from 35A to 35A.
When switched to any one of B to 35D and turned on, the miniature light bulbs will become 28c and 28d, 28e and 28h, and 28f by the same timer and relay operation as above.
and 28g, and the eyeballs can be moved in any of B, C, and D modes.

Also, when only the mode selection switch 35E is closed, the miniature light bulb 23 lights up and the relay 41 is turned on.
is energized. As a result, the electric motor 15 rotates forward,
The rotary disk 10 rotates in the clockwise direction, and the light from the miniature light bulb 23 is guided to the light guide 13, whose tip emits light while rotating in E mode. When closing only the mode selection switch 35F, the relay 42
The electric motor 15 is reversed by the energization of the light guide 13.
The tip emits light while rotating in F mode, which is a counterclockwise direction. In the E and F modes, the color of the light emitted from the tip of the light guide 13 changes every moment due to the rotation of the color disk 22, which can be enjoyed.

As described above, various eye movements are performed while selecting the appropriate mode, and when the time specified by the timer 43 is reached, the contact 43a opens to deenergize the relay 36, and the operation of the device is terminated. . Note that even before the time limit of the timer 43 is reached, the operation of the device can be ended by pressing the push button switch 33. While the device is in operation, the ventilation fan 29 rotates to raise the temperature inside the dark box 3.
Prevents humidity from increasing due to exhalation.

As mentioned above, this invention allows the eyeballs to perform various modes of movement, especially rotational movement, contributing to recovery from eye fatigue, training of eyeball muscles, and prevention of aging.
