eye exercise device

Abstract

To provide an "eye exercise device" that can automatically and unconsciously avoid "eye economy syndrome" even while working or studying. [Solution] The stand 2 consists of an upper stand 3 that can move back and forth and a non-movable lower stand 4. The upper stand 3 is equipped with wheels, ball bearings, opposing magnets, etc. (for example, four wheels or more, not shown), and can only move back and forth on the lower stand 4. A monitor 5 is placed on the upper stand 3, and as the upper stand 3 moves back and forth, the monitor 5 also moves back and forth. As a result, the user looking at the screen of the monitor 5 changes the focus of their eyes in accordance with the movement of the monitor 5, so they unconsciously view the monitor from a single focus to a multi-focus view. This results in natural eye exercise, preventing ocular economy syndrome.

Description

[Technical Field]

[0001] The present invention relates to an eye exercise device used to relieve eye fatigue and prevent deterioration of eyesight. [Background technology]

[0002] In modern society, there are many opportunities to look at monitors such as computers and televisions, or magazines and books for long periods of time, and many people have experienced blurred or painful eyesight. The cause of this eye disorder is thought to be "ocular economy syndrome," which occurs when the eye's lens is not moved in order to fix the focus of the eye on the same subject.

[0003] A conventional preventative measure for eyes is to temporarily look away from a monitor such as a computer or television and gaze at a distant subject (see Patent Document 1, etc.). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3121452 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when concentrating on work or study, or playing video games with a third party, it is extremely difficult to consciously look away from a monitor or book and focus on a different distant subject.

[0006] Therefore, the present invention was completed with the aim of making it possible to automatically avoid "eye economy syndrome" without even being aware of it, even while working or studying.

[0007] The present invention is as follows. The first invention is an eye exercise device comprising a stand on which a monitor or equipment or printed material equipped with a monitor is placed, and a movement mechanism for moving the upper part of the stand back and forth, the movement mechanism using a worm-geared motor as power and connected to the upper part of the stand via a conversion member that converts the rotational motion of the motor shaft of the motor into back and forth motion, and by continuously moving the upper part of the stand back and forth, the focus of the eyes looking at the monitor is automatically switched from single focus to multi-focus. The second invention is an eye exercise device according to the first invention, characterized in that it is equipped with a motor emergency load stop prevention function that prevents the rotational movement of the motor shaft of the motor from being linked to the conversion member in an emergency. [Effects of the Invention]

[0008] The present invention has the following advantages. (1) The upper part of the stand on which the monitor, equipment with a monitor, or printed material is placed moves back and forth continuously, causing the eyes of the user looking at the monitor to change from a single focus, where the eyes are fixed on one point, to a multi-focus, where the eyes are constantly moving, where the eyes are constantly moving, thereby naturally preventing eye economy syndrome without the user even realizing it. (2) The eye exercise device is equipped with a motor emergency load stop prevention function that does not link the rotational movement of the motor shaft of the motor to the conversion member in an emergency. This makes it possible to avoid the motor from being stopped due to a load being placed on the motor even if the upper part of the stand stops operating due to a problem with the stand or the intrusion of foreign matter into the stand. [Brief explanation of the drawings]

[0009] [Figure 1] FIG. 1 is an explanatory diagram (1) illustrating an embodiment of the present invention. [Figure 2] FIG. 2 is an explanatory diagram (2) for explaining an embodiment of the present invention. [Figure 3] FIG. 3 is an explanatory diagram for explaining an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the "eye exercise device" according to the present invention will be described below with reference to the drawings. The present embodiment described below is an example of the present invention, and the present invention is not limited to this.

[0011] FIG. 1 is an explanatory diagram (external view) of an "eye exercise device 1" according to the present invention. As shown in Fig. 1, the gantry 2 is made up of an upper gantry part 3 that can move back and forth and a non-movable lower gantry part 4. The upper gantry part 3 is fitted with wheels (for example, four or more wheels, not shown) and can move only back and forth on the lower gantry part 4. Instead of wheels, known technology such as ball bearings or reciprocal magnets may be used to allow the upper gantry part 3 to move only back and forth relative to the lower gantry part 4. The monitor 5 is placed on the upper part of the stand 3, and as the upper part of the stand 3 moves back and forth, the monitor 5 also moves back and forth. As a result, the focus of the user's eyes changes according to the movement of the monitor 5, and the user unconsciously changes from single focus to multi-focus when looking at the monitor. This results in natural eye exercise, which is expected to prevent eye economy syndrome and improve eye fatigue and eyesight.

[0012] FIG. 2 is an explanatory diagram (structural diagram) of the "movement mechanism" of the "eye exercise device" according to the present invention. Symbol A is a worm geared motor. Reference symbols B and C are conversion members in which flat bars (FB) are rotatably connected. Reference symbol D denotes a part of the upper part 3 of the frame.

[0013] The movement mechanism converts the rotational motion of the motor shaft 10 into forward and backward motion as follows, using A to C above. In other words, the rotational motion of motor shaft 10 of A is transmitted to B. One end of B is connected to the motor shaft of A, resulting in rotational motion. C is connected to the other end of B so that it can rotate freely, and is also connected to the upper base 3, and the movement direction of the upper base 3 is restricted to the forward and backward direction by the lower base 4, so the rotational motion of B is converted into forward and backward motion by C. This allows the upper base 3 to move forward and backward. Note that B may be a disk instead of FB. Furthermore, although A to C are installed on the lower gantry 4, they may be installed on the upper gantry 3. In this case, there is an advantage in that the gantry 2 can be made thinner.

[0014] FIG. 3 is an explanatory diagram (structural diagram) of the "motor emergency load stop prevention function" of the "eye exercise device" according to the present invention. Reference numeral 10 denotes a motor shaft. Reference numeral 20 denotes a motor power transmission pipe. Reference numeral 30 denotes a long screw. Reference numeral 40 denotes a round rod-shaft push pin. Reference numeral 50 denotes a round urethane rubber rod. Reference numeral 60 denotes a push-in bolt for 40 and 50.

[0015] The motor emergency load stop prevention function is structured as follows, by the above 10 to 60, so that the rotational motion of the motor shaft 10 rotates freely relative to the motor power transmission pipe 20 (a component for transmitting power to the flat bar B). In other words, if an accident such as a foreign object being mixed into the stand 2 occurs, 10 and 20 can be temporarily made non-contact (sliding = spinning freely), which structurally prevents the motor from being loaded and stopping. To make 10 and 20 non-contact, simply adjust the screw tightening of 60, which is behind 50 that presses 40 from behind. [Industrial Applicability]

[0016] The "eye exercise device" of the present invention can be widely used by people of all ages, from children to adults, as a device for preventing "eye economy syndrome," and ultimately for relieving eye fatigue and preventing or restoring vision loss. [Explanation of symbols]
