JP5258095B2 - Eye muscle training device - Google Patents

Description

The present invention relates to a training apparatus for recovering and improving visual acuity of a person whose visual acuity has deteriorated due to a decline in the function of eye muscles.

The eye muscle training device of Japanese Patent Application No. 2004-174830 (publication number: Japanese Patent Application Laid-Open No. 2005-329185) has excellent advantages in that the strain of the eye muscle is eased as a training device, but the storage property and the outdoors, etc. The length of the guide bar makes you feel inconvenient when you take it out. Furthermore, it is effective to increase the number of reciprocations for “far and near” training, but since there is no count indicator, it is inconvenient for training management.

JP 2005-329185 A4

In the content of Japanese Patent Application No. 2004-174830, the guide bar needs a mechanically continuous structure to move the indicator, so that the length of the guide bar makes it feel inconvenient to take a place when carrying and storing. . Furthermore, I feel that training for increasing the number of reciprocations is necessary for training in the perspective direction for ciliary muscles compared to other eye muscle training. I feel inconvenience. The problem was to eliminate these inconveniences.

A small lamp consisting of 11 LEDs, etc., is installed on the guide bar at regular intervals. When the power switch is turned on, it automatically turns on and off automatically in sequence, and continues to reciprocate while looking at the lighted small lamp. The tracking method enables eye muscle training according to the moving index method as if tracking the reciprocating index with a line of sight, and the guide bar structure is divided into three parts and a gear mechanism is incorporated. This makes it possible to fold a long guide bar compactly at equal angles (symmetrical) from side to side. By replacing the indicator with a small lamp and eliminating the moving mechanism, the guide bar itself can be reduced in weight and saved in storage. Furthermore, training management can be facilitated by installing a counter that moves up every fixed number of round trips.

As a result of the eye muscle training method, a new training method in the V-shaped and reverse V-shaped directions could be added as a result of the combination with the gear mechanism.

In the training in the perspective direction, taking into consideration the risk of the eyes directly hitting the end of the guide bar due to sleepiness during training, etc., a cushion for safety is provided at the tip so that the eyes do not pose a danger.

Switching the position of the guide bar (each position of the guide bar at the time of training is referred to as “mode” in the following description) can be “automated” by using a reversible rotating small motor with a built-in reduction gear. However, from the viewpoint of cost-effectiveness, the mode is switched manually.

The present invention can bring out the same effect as the content of Japanese Patent Application No. 2004-174830 by a simpler method, and in addition to facilitating training management and realizing space saving during storage, New training mode can be added.

1 to 4 show the outline drawing and usage procedure of the present invention, and FIG. In this device, each LED 17 is automatically turned on and off sequentially by pressing the power switch of the operation box 33 after being connected to the power supply, so that the reciprocation continues continuously. At the same time, the guide bar is set to an arbitrary mode, and the eye muscles are trained according to the procedure of each procedure.

  The main configuration of the present invention includes a leg portion, a fulcrum portion, a guide bar portion, and an operation box. Details of the configuration of the embodiment will be described below.

  The leg part is composed of only the leg 1 for stable installation of the apparatus on a flat surface. When the screw part and the fulcrum part for contact with the support column 2 of the fulcrum part are rotated 90 degrees. The stopper has an integral structure. (See Figure 6)

  At the bottom of the fulcrum portion, a screw cap 21 for connecting to the leg 1, a positioning piece 19 and a set screw 20 at the time of 90 ° rotation are attached. In the upper part, the receiving portion when the guide bar is stored is constructed integrally with the support column, and a lever 18, a restoring spring 22 and a push plate 23 for opening the guide bar are incorporated between them (see FIG. 8). . These are assembled before the set screw 20 is attached. By depressing the lever 18, the ring 26 provided on the guide bar A5 and the guide bar C7 is expanded to the left and right by the push plate 23, the receiving part is opened, and the guide bars A and C can be opened. A seat for mounting the operation box 33 is provided at the center of the support column, and the jaw receiving seat has an integral structure at the upper portion, and the jaw receiving 14 is attached. Further, a fulcrum A10 and a fulcrum B11 for supporting the guide bar portion are attached to the upper surface by a screw, and the ball bearing 9 is incorporated. A nose pad 13 is attached to the front surface of the fulcrum A10, and a counter 34 and an electric wiring cover 35 are attached to the fulcrum B11 side.

The guide bar portion includes guide bar A5, guide bar B6, guide bar C7, connecting plate A3, connecting plate B4, LED 17, LED mounting seat A30, LED mounting seat B31, LED mounting seat C32, protective cushion A15, cushion B16, It consists of a gear 8, a plunger 12, and a small fastener.

In the guide bar A5 and the guide bar C7, the rotating shaft at the time of folding and the teeth meshing with the gear 8 have an integral structure and are connected to the connecting plate A3 and the connecting plate B4 by small parts fastening parts, respectively. The gear 8 is attached to the inside of the connection plate A3 by a small fastening component. Further, the connecting plate A3 and the connecting plate B4 each have an integral structure for rotating shafts for tilting the entire guide bar at the time of mode switching, and the shafts are fitted into the ball bearings 9. The shaft portion is provided with a wiring extraction hole.

The guide bar B6 is located between the connection plate A3 and the connection plate B4, and is fixed to the central portion of the connection plate B4 with a small fastening component, and the LED mounting seat B31 and the LED 17 are attached.

Each LED has a transparent cover and tape for diffusing light displaying characters and symbols (A, B, C, X, ◎, ☆, Randolt ring, Katakana, Hiragana, Kanji, etc.) Etc. to protect the eyes when looking directly at the LED from directly above, and to make the eye muscle training effective by trying to recognize the display according to the timing of lighting.

The plunger 12 has a structure in which the position of the guide bar can be set at a pitch of 15 ° by the plunger 12, and the mode can be switched within a range of ± 60 degrees (see FIG. 9).

In the perspective mode, the guide bar A5 and the guide bar C7 are angled about 4 to 5 degrees from the horizontal so that the LEDs do not overlap each other on the line of sight, and the connecting plates 3 and 4 are moved as shown in FIG. Rotate 15 degrees for training. The counter 34 is prepared for training in the near and far direction, and it can be started by returning the count to 0 by pressing the reset button attached to the operation box 33. It is programmed to go up once every 15 round trips and can count up to 99 times.

Training in the V-shaped and inverted V-shaped modes can be performed with the guide bar set as shown in FIG.

The operation box 33 includes a DC power connector, an illuminated power switch, a count reset switch, a control board, a buzzer, and small parts.
The operation is performed by connecting a DC power source, first leveling the guide bar, and then pressing the illuminated power switch. The LED turns on and off in sequence, plays a single beep at each turn at both ends of the guide bar, plays a single beep at the 5th and 10th rounds, and changes modes at the 15th round. This is also a signal for the third time, and the same three notes as every five reciprocations are played once. After every 15 reciprocations, the posture of the guide bar is changed manually and the mode is switched.

When the training apparatus is stored, it is folded as shown in FIG. 5 and a protective cover A36 and a protective cover B37 are attached for LED protection.
