Description

Gravity pendulum action myopia-preventing and kyphosis-preventing equipment

The present invention is a kind of myopia prevention, anti-bow-backed device.

In the prior art, " attraction children's vision protector ", publication number are CN1087808A, it can not with look object distance from correction and automatically the sight-shielding plate of turning down is opened.

Purpose of the present invention be exactly to design a kind of can with look object distance from variation and stop automatically or open sight line, the myopia prevention of the pronunciation of pronouncing prompting automatically or stopping, anti-bow-backed device, stop people closer to read and write thing unawares solidly, eliminate the basic factor that myopia takes place.

Concrete technical scheme is: see Fig. 1, Fig. 1 is a fundamental diagram, is that tack (9) is positioned at the end of spectacle frame from the observed view in user the right.Be provided with one or a gravity bob (7) respectively is set in both sides as required in the side of spectacle frame (1), swaying direction is front and back.Suppose (to vary with each individual, because people's vision level difference) when people are in correct sighting distance, gravity bob (7) is A with the projection angle of lens frame face (2).(it is because tilt when using that figure tilts).Because the center of gravity of pendulum was parallel with gravity vertical all the time with the line of center of rotation when gravity bob (7) was static, when people closer read and write thing unawares, head will be lowly, and gravity bob (7) can rotate, and included angle A can increase.The present invention utilizes this rotation to remove closed circuit switch (C and D) exactly or promotes blade rotation, thereby pronunciation prompting or block vision reach myopia prevention, anti-bow-backed purpose with this.When people recovered correct sighting distance, gravity bob (7) will backward rotation, and prompt tone can stop, and the sight line that is blocked can be opened.In order to prevent the read-write of child's torticollis, can be arranged on the gravity bob (see figure 5) that can both swing on the both direction, achieve the goal with same operation principle.

Advantage of the present invention and good effect are: simple to operate, highly sensitive, full-automatic.Can stop people closer to read and write thing unawares, correct the read-write posture of their mistake, myopia prevention, anti-bow-backed.To the myope, can prevent the further intensification of myopia.

Fig. 1 is a fundamental diagram, and Fig. 2, Fig. 3, Fig. 4 are three embodiment of the present invention, and Fig. 5 is the gravity bob sketch map (amplification) that can both swing on both direction.

Fig. 2 is one embodiment of the present of invention, and the person of being to use picks up the glasses view of oneself seeing (non-other people see) before glasses will be put on.Go up with screw, installation of nut form and the insulating battery case of metal spectacle frame (1) (10) at the intermediate transverse girder (15) of metal spectacle frame (1), can adorn button cell in the box.A switch (11) is set, so that cut off the electricity supply when need not or not read and write on the battery case (10).With lead the anelectrode of battery and the electrode E (two places) of liquid mirror eyeglass (12) are connected, another electrode B on the liquid mirror eyeglass (12) (two places) is connected with metal spectacle frame (1).The reuse lead is connected the negative electrode of battery and the C electrode of gravity bob trigger-type contactor, C electrode and metal spectacle frame (1) insulation.Gravity bob (7) is made of metal, and be installed in metal spectacle frame (1) with the metallic screw that the smooth face of cylinder is arranged and go up and conducting, and can freely swing (frictional resistance is very little).Electrode D on the gravity bob (7) constitutes gravity bob trigger-type contactor with above-mentioned electrode C.When people put on these glasses, when being in correct sighting distance (varying with each individual, because people's vision level difference), the center of gravity of regulating gravity bob (7) makes electrode D soon contact with electrode C.When people began closer to read and write thing unawares, gravity bob (7) will rotate, and electrode D will contact conducting with electrode C, and liquid crystal lens (12) will turn black, and sight line will be blocked or disturb.When people recover correct sighting distance, gravity bob (7) meeting backward rotation, liquid crystal lens (12) will be transparent, and sight line can be opened.There is the center of gravity governor motion (8) of a pendulum lower end of gravity bob (7), and it adopts screw, nut structure form, the slide block and the gathering sill structure that also can adopt certain friction can not become flexible.Liquid crystal lens (12) has two electrodes of B, E to connect liquid crystal film on the eyeglass.Liquid crystal film can be whole laminated structure (full barrier type) or bar shaped reticulate structure.The bar shaped reticulate structure has prompting-type and interference type: bar shaped reticulate pattern sparse (extremely sparse is certain bar line, certain word or letter), and can see major part clearly or all read and write thing is prompting-type; The bar shaped reticulate pattern is very intensive, can not see the interference type that is of read-write thing clearly.Can consider during design two kinds of structural shape combinations are are closer read and write in the process of thing people, disturb prompting earlier, back.Spectacle frame can be nonmetal, but circuit and mounting means will redesign.

The direction that further develops of liquid crystal lens (12) is to unite two into one with concave lens, and liquid crystal lens can be made with reference to the processing technology of " palm PC " and " Tetris ".

Fig. 3 is an another embodiment of the present invention, is that tack (9) is positioned at the end of metal spectacle frame (1) from the observed view in user the right.Miniature gear gear (4) be welded on metal spectacle frame (1) both sides (about each one, can make of existing clock and watch technology), there is an axle (3) inside (that direction of the bridge of the nose) to stretch out below the spectacle-frame upper edge on the blade gear, blade (5) can be installed.On outside (glasses both sides) projecting shafts (6) of gravity bob gear, gravity bob (7) can be installed.There is the center of gravity governor motion (8) of a pendulum lower end of gravity bob (7), and structural shape is identical with the embodiment of front.When people are in correct sighting distance, the center of gravity of pendulum is transferred to the natural opening of blade (5).Blade (5) is the thin slice made from the very little material of proportion, and will consider its static equilibrium with respect to rotating shaft (can reduce motive force).The requirement of gear shift (4) is: the direction of rotation of the direction of rotation of speed change rear blade (5) and gravity bob (7) opposite (clockwise, and another is counterclockwise).In-house frictional resistance is as much as possible little.Gear ratio is big more, and sensitivity is just high more, but frictional resistance will be big relatively, generally can select gear ratio between 20 to 30.Present embodiment also can be applicable on the existing glasses for the myopia, to prevent the further intensification of myopia.Spectacle frame can be nonmetal.
