Abstract

The present invention is particularly used for correcting nearsightedness or training to further enhance a visual function for persons with normal vision and is in a portable headgear type. A lens assembly is pushed to zoom back and forth relative to a true object scene with spiral spring energy storage as dynamic force by the restrict and the conduction of an energy releasing system. Thus, ciliary muscles are induced to exercise to be regulated correspondingly. A pause switch and a focal power instant display are additionally arranged on an instrument which can also be used as an eye refractometer. The present invention is divided into a single-barrel type and a double-barrel type, and a zooming range can be adjusted. The lens distance between the double barrels of the double-barrel type can be adjusted so that the instrument is suitable for people with different interpupillary distances.

Description

Single, double tube wear-type autozoom training for vision correction instrument

Utensil of the present invention system takes exercise and improves a kind of myopic eye preventing and treating instrument of eyeball to video focusing ability, and the person that also can be used as the emmetropia further improves a kind of auxiliary sports training apparatus of visual function.And can use by the double as eye refractometer.

Existing like product is to be power with electronic or hand operated, by convex lens and the photochrome that moves repeatedly, constitutes the zoom view, and before eyes returning toward constantly zoom motion regulated the improvement vision to induce ciliary muscle.These product shortcomings have three, one: volume is big and heavy, particularly electronic, only adapts to the fixed-site medical health department to use, and inconvenience is flowed and portably used, and cost is also very high.Its two: because they are sensation target with fixing photo all, lose the various outdoor scene sense effect of prepossessing appearance, be unfavorable for training the further raising of visual sense function in latter stage.Its three: manual correcting instrument can be taken into account the cooperation that commander manually does because of brain in use, and consciousness force is disperseed, and is unfavorable for to the ciliary muscle centralized Control single-minded raising.Purpose of the present invention is for addressing the above problem, and reaches light, automatic, multi-functional, physical cultureization, high effect.So there is not above-mentioned shortcoming in this utensil.Its profile is to make the specular wear-type of similar eye, and is miniature, and being convenient to flow portably uses.Accumulation of energy with clockwork spring is a power again, and is energy-conservation convenient again.Be not visual object with the picture, and with a convex lens and concavees lens under its clockwork spring elastic force drives, return toward constantly zoom motion, the adjusting of inducing ciliary muscle to do focusing is taken exercise, and makes the vision raising.During use, be directly to train facing to " visual acuity chart " or scene in kind, visual sense is effective.But according to the also double as eye refractometer use of its attachment mechanism.This utensil is made single cylinder type and bitubular type two kinds, and they all have can cover an eye, carries out single-minded function by the eye exercise.Bitubular type also has spy's energy that eyes are also practiced simultaneously, and can also adjust the distance between two lens barrels.The different eye distance persons that adapt to child adult use.

Be in conjunction with the accompanying drawings its structure to be described in further detail below:

One, the description of single cylinder type wear-type autozoom training for vision correction instrument structure and operation principle:

As shown in Figure 1,, constitute power source and hold laying mechanism to drive sprocket axle (2) and steel bomb power bowl (3) with drag for the parts that wheel (4), clockwork spring (5) are connections by knob (1).Can tighten its clockwork spring by knob (1), and discharge elastic force by drivewheel (4) tooth, externally put rotary torsion to good use, above-mentioned formation is generically and collectively referred to as initiatively train (about its internal structure, by hereinafter describing separately, this section is omitted).

When elastic force is reversed in the external release of active train, it at first is the bottom small-diameter gear of passing to driven pulley (6), driven pulley (6) is again by the coaxial large diameter gear above it, elastic force is passed to driven gear (7), driven gear (7) is passed to driven gear (8) to elastic force by its coaxial large diameter gear again, since by drivewheel (4) to driven pulley (8), gear ratio all is than lacking by many between transmission, so its elastic force weakens step by step, pass when reaching driven pulley (8) through three grades, elastic force is just more weak, accelerates step by step but pass speed.Because take turns in the big footpath on the driven gear (8), its tooth is to make to carry rotation direction (direction shown in the arrow among the figure) deflection on one side, and in the rotation, the many ends in its inclined plane constantly collide two straight-bar (a) and (b) on the escapement (9) respectively.Its escapement (9) just swing gets up, and the rotating speed of restriction driven pulley (8), from and define the rotary speed of drivewheel (4), also just define the rotary speed of driven pulley (6).Owing on driven pulley (6), be connected with the coaxial wheel (10) that inclines, the wheel (10) that inclines tilts with respect to its cutting plane, so its wheel rim is and swings up and down when rotating, from and promoted to shoulder bar (11) motion that and then teeters, shaking of bar (11) shouldered in transmission, having promoted movable shuttle axle (12) again moves up and down, because movable shuttle axle (12) is gone up affixed a movable lens (13), thereby, its movable lens (13) is also along with shuttle axle (12) is done to move repeatedly up and down, this moving repeatedly constantly returned the relative distance that changes it and fixed position lens (14), owing to their both convex-concaves are opposite pastly, thereby constantly return toward the complex focus that is changing them, realize the effect of continuous zoom, induce ciliary muscle to do the corresponding exercise of regulating, improve the purpose of vision and reach.

Above-mentioned movable lens (13) is made directly (or solid mutually indirectly) for the high index of refraction light material and is cast from admittedly on the shuttle axle (12), its mirror also can be to form with ordinary lens materials processing, its focal length can be-2.86 centimetres, movable stroke can be about 0.5 centimetre, convex lens (14) focal length can be+and 3.86 centimetres, convex lens is embedded in the spiral cover (23), spiral cover (23) spins by the same shell of its screw thread (17), and be subjected to two symmetric top springs (24) and (25) (and for example Fig. 2 shows) elastic force press, make it be unlikely loosening.Be printed on scale (21) on the limit leaf of top spring (24), (e) is corresponding with vernier, with the usefulness of indicating degree.About 4～6 times of mirror group zoom per minute, zooming range can be determined by regulating the position of its spiral cover in shell according to each user eyesight status difference.But general adjustable in popular diopter+100～-421 degree scopes, the zooming range number of degrees after the setting can expose on scale window (20) (be embedded in shell by lucite and form, as Fig. 5).There are four rotations to see Fig. 5 on spiral cover (23) the face circle with turning round hole (f).

Above-mentioned index glass also can be set to convex, and horizontal glass is a spill, but video will diminish relatively.Each wheel shaft among Fig. 1 is by up and down two metallic plates supportings, and makes elasticity distance adjustable (Fig. 1 shows) structure (k) at escapement (9) axle head, so that adjust, the swing of escapement (9) guaranteed flexibly.

Shuttle axle bed (15) is the steel drift goods, and is connected with shell.Or once form in shell by the polymer disjunctor.Shuttle axle bed (15) both sides by edge (16), can make lens (13) relative with horizontal glass energy held stationary ground photocentre when returning toward motion with index glass.

Internal structure about the active train is described: as shown in Figure 3, the protruding base of a fruit (c) is arranged on the drive sprocket axle (2), be embedded on the clockwork spring (5), and restricted by its elastic force.Drive sprocket axle (2) is consolidated riveted (seeing A-A) with steel bomb power bowl (3) with shuttle again mutually, and so the energy interlock is with being subjected to clockwork spring (5) restriction.But the same drive sprocket axle of drivewheel (4) (2) does not directly correlate relation, and only continuous action relation takes place the frictional force that is in contact with it by steel bomb power bowl (3).This frictional force (refers to the elastic force direction rightabout that with clockwork spring transmit be reverse direction to the reverse that knob (1) takes place less than staff when winding up, otherwise for just changeing, torsion down together), so when winding up, (the driven pulley system can not reverse in fact in the driven pulley system rotational resistance restriction that is not subjected to drivewheel (4) and correlates, because the big footpath gear teeth on the driven pulley (8) are made to the reverse direction deflection, see Fig. 1,4, be subjected to two straight-bars (a) of escapement and restriction (b), formation can only just be changeed, and the situation that can not reverse), seem easily and freely.But during drive sprocket axle (2) the clockwork spring elastic force function that it is just changeing in release, can drive each driven pulley again just changes.This is the frictional force that drivewheel (4) is formed because of steel bomb power bowl (3), greater than the various rotational resistances of driven train.The clockwork spring accumulation of energy of this member, enough these parts move more than half an hour continuously.

Description about auxiliary function refraction system principle and structure: as Fig. 1,2,4,5, shown in, refraction system is made of brake switch (19) and index glass vernier (e) and scale window (20), scale scale (21), and wherein brake switch (19) is to live in being embedded on the face-piece (17).Fig. 4 shows, when optometry person watches " visual acuity chart " attentively when obtaining suitable clear video, at once brake switch (19) is advanced to the direction of arrow shown in the figure, pawl spring (d) is promptly exerted pressure to escapement (9), prevented the swing of escapement, thereby make whole dynamical system out of service, at this moment, there is a vernier (e) (Fig. 1 shows) at the outer rim place of moving concave mirror, also be in resting state, and show its scale (21) by its scale window (20) (Fig. 5 shows), thus obtained the optometry data, realized the purpose of optometry.Fig. 4 right side is reference type brake structural figure.

Monotubular instrument for training profile as shown in Figure 5, shell (17) etc. is made attached elastic bandage (22) by injection moulding.Expose the knob of winding up (1) and suspend brake switch (19) and eye refractometer scale window (20) vernier (e) scale (21).With center line BC is directrix, and the both sides profile is symmetry substantially.Make in actual use, practiced an eye after, it is turned to another direction wears, can continue and practice another eye, realize the usefulness of two wheel usefulness of a glance window.

Two, the structure and the principles illustrated of similar series of products a pair of cartridge type wear-type autozoom training for vision correction instrument:

Bitubular type sight training instrument profile as shown in Figure 6, form by two lens barrels, before placing two eye sockets respectively, the power main part is arranged on inclined to one side slightly forehead position between two lens barrels, and expose the knob of winding up (26), two fixing convex lenss (29), (30) be embedded in two spiral covers (27) respectively, (28) in, its spiral cover is by same respectively two lens barrels (31) of screw thread, (32) correspondence spins, two spiral covers are with two lens barrels (31), (32) elasticity that spins is subjected to all separately that a pair of top spring force of inner face presses, and top spring shape and principle be single cylinder type instrument for training top spring (55) roughly the same, (56) (integrate with Fig. 2 and show it).Branding has scale scale (57) on the leaf of top spring (55) limit, divides scale window (37) that other correspondence is exposed to two lens barrels, (38) (inlayed form by lucite and lens barrel shell).And constitute the focal power display with vernier (M) (Fig. 2,8) respectively, and go out degree by adjusting each spiral cover precession, can reach and adjust its focal power excursion and demonstration.This structure, those two eyeball myopic degree persons of differing that are more convenient for adjust use.(n) in the accompanying drawing is spiral cover torsion hole.

Distance can be adjusted according to the user eye distance between two lens barrels (31), (32).Structure and principle are as shown in Figure 7, promptly make groove (g), (h), (i), (j) at the place of Square-edge separately of two lens barrels (31), (32), divide corresponding with lens cone seat (33) in addition, make two lens barrels (31), (32) can be respectively advance or pull out and aim at a center to the center of lens cone seat (33), behind the appropriate location of accent, fastening by the relevant screw of lens cone seat bonnet.This adjustable body tube device is more convenient for adapting to adult, the different eye distance people's of child use.

And for example shown in Figure 6, before two lens barrels, be provided with a movably pushing cover (34), this pushing cover can move along its groove (35), (36) track up and down.The sight line of two any one lens barrels about can blocking with this is concentrated idea so that carry out, and single-minded simple eye training is when needs are done binocular balance combined training, as long as in the middle of this lid pushed to, just brought into play the effectiveness that two lens barrels act on simultaneously.

Above-mentioned housing constitutes by injection moulding, and an attached elastic bandage (54) is for wearing firmware.

About its internal mechanism, shown in Fig. 8,9, dynamic component is the instrument for training structure of single cylinder type roughly the same, still by active train (40) (its inner structure with Fig. 3 merge show it) driven pulley (41) and the coaxial wheel (42) that inclines, driven pulley (43), (44) escapement (45), transmission shoulder bar (46), shuttle axle institutes such as (47) forms.Difference is that varifocal mirror increases by one group, and promptly moving horizontal glass respectively increases by one.Index glass is concavees lens (48), (49), is directly to cast from link arm (50), (51) face one-tenth (Figure 10 shows) respectively admittedly with transparent high index of refraction light material.Link arm among the figure (50), (51) and shuttle arm (52) are pressed into the semicircle tube by metallic membrane (rustless steel etc.), and link arm is merged into the wholecircle tubulose with shuttle arm two ends respectively, and be solid by steel wire helical spring pipe (53) cover, scalable twitch (Fig. 8 shows).This structure purpose is for two index glass (48), (49) are adjusted in the lump according to user eye distance situation and fixed lens barrel.Shuttle arm (52) motion also is subjected to the support of two weighing apparatuses fixed prominent (58) and makes its stable operation.

Above-mentioned index glass also can be designed to protruding, and horizontal glass is a spill.

Bitubular type instrument for training adnexa refraction system constitutes and principle is analogous to the single cylinder type instrument for training, is promptly still finished with above-mentioned focal power display by suspending brake switch (39) (Fig. 4,6 shows).

Remaining principle and specification requirement are analogous to the explanation of single cylinder type instrument for training, and this section does not repeat.

The secondary name of this serial utensil: wear-type autozoom vision correction, optometry double-purpose instrument.

Three, about the Practical significance of this utensil:

As shown in figure 11, the abscissa express time carries out, vertical coordinate is the vision progress, the progress that can see visual training is to be the stage in cycle in time to change, process from quantitative change to qualitative change promptly from " stupid keeping the phase " beginning, carries out the transition to " unstable idiophase " so that " stablizing the raising phase ", resemble the inclined to one side band (Figure 12) of a rotation, so claim " bandlet rule ".So-called " stupid keeping the phase " is meant that the beginning white silk is initial, eye disease patient myopia state is deep-rooted, malleable not, must lead by this utensil and practice a period, make it to divide and disintegrate to certain vision basis, go bore hole more directly facing to " visual acuity chart " training of following up a victory with hot pursuit, and do not reducing under the horizontal situation of near vision, by zooming out the sighting distance training period, be limit target until the 15 meters standards that can see the minimum E of delegation clearly; Or stare distant view, and the turnover motion pan of combined high-strength eyeball is taken exercise: in conjunction with boxing, blue ball, table tennis exercise with consolidation etc.This is because looking the function structure is an integral body, is to be made of multiple factor, not only improves and the development vision by the ciliary muscle function merely.Research theory and practice all show to have the teenager on appropriate myopia basis, behind the regular period distant vision balance training by this utensil and these works, will can obtain the ken and the better visual sense effect wideer than common emmetropia person on the contrary.Monograph " teenager vision correction sentific training method---the New Physical Culture theoretical lecture " books (be aim at this utensil is supporting to be shown) that concrete theory and methods and rules for military drill or physical exercise see this researcher for details have nothing to do because of itself and this patent, and this paper is not described further.

Its meaning is traditional myopic eye preventing and treating only rested on asking recovery from illness be the medical character of purpose, rises to ask the physical significance standard of evolving and developing into target to implement, and brings into play by the effect of this utensil.Filling up and list universities, middle and primary schools, military universities and colleges' sports item in, promote and carry out the competition competition, improve the development in an all-round way of sports, is to save human facing from the effective measures of more educated variation for myopiaization.To improving the vision quality of whole nationality, profound significance is arranged all.(Figure 13 is that the exercise induced ciliary muscle of mirror group zoom is done corresponding adjusting exercise principle signal)
