Abstract

A kind of health glasses for reading and writing that can make the people not bow and write and read, these glasses are made object lens with one group of level crossing, make eyepiece with another group level crossing, object lens are relative with the reflecting surface of eyepiece, middle in an acute angle, object lens are fixed on the picture frame by the object lens rotation axis, and can in sliding to groove, change and eyepiece between angle, construct extremely simple.Yet because the effect of its special optical system and regulating system, the eyeglass area is little, and whole glasses are lightly exquisite, sight is big as scope, and the height of image space is adjustable, and imaging does not have distortion, does not dwindle, clear bright, can be used for the official documents and correspondence write-read of writing and couch, remove the sorrow of people's write-read sufferer.

Description

Health glasses for reading and writing

The present invention relates to a kind of health glasses for reading and writing that can make people not bow and write and read.

Since ancient times, people particularly when official documents and correspondence is write, must sit up straight the table side at reading learning, and two elbows prop up on the table, bend over the desk to bow, and neck, waist are all in tension, very easily fatigue damage.According to statistics, be engaged in the people that official documents and correspondence is write work for a long time, the overwhelming majority suffers from cervical vertebra or lumbar vertebra disease in various degree, and the severe patient head can not be low, waist can not be bent, and is agonizing.For solving this difficult problem since ancient times, people take all means, have done all effort.As Chinese patent 86200353 horizontal reading mirrors, use precision machined 30 ° of right-angle prisms to make eyeglass and make difficulty, cost an arm and a leg, inconvenience is worn and is promoted.Chinese patent 86209052 health care enocscopes and for example, the level crossing that uses two one-tenth＞shape 45s to link into an integrated entity is made eyeglass, is worn on the crown with hatband, though structure is simple, because level crossing＞the shape structure, produce repeatedly reflection, imaging is mixed and disorderly in the mirror, and far away apart from eye because of minute surface, the visual field is narrow, desires to broaden one's vision to increase the area of level crossing, the result increases the weight of mirror, do not have the assurance of support again, be worn over and make jitter in the mirror on the crown, harm one's eyes.Simultaneously, because＞the shape structure, have only the light of close health just might reflex in the eye and be observed, promptly the minute surface of stretching from upper flat is done vertical line to desktop, as shown in Figure 1, puts down the minute surface M that stretches ₁Vertical line NN ₁And the object between the person PQ just might be observed by eyes, like this range of observation just extremely limited use very inconvenient.The OMF glasses of Chinese patent 89219602 for another example, eyeglass adopt that prism structures is compound so just to make the precision of processing and manufacturing improve greatly with suitable lens or compound suitable post mirror in addition, cause the production difficulty big, and price is costliness more.Up to the present, the glasses of also do not have a kind of simple structure in the world, producing easy, cheap and function admirable, be easy to promote.

Purpose of the present invention, the glasses that will provide a kind of simple structure, made people easy to manufacture, function admirable not to bow and read and write exactly.

The object of the present invention is achieved like this: as object lens, make eyepiece with another group level crossing with one group of level crossing, object lens are relative with the reflecting surface of eyepiece, and are middle in an acute angle, constitute lambda shape; Eyepiece is fixed on the picture frame, and object lens are fixed on the picture frame by the object lens rotation axis, can the object lens rotation axis be that rotate in the axle center; And on picture frame, be provided with the groove that slides to that changes the object lens angle, use the position of adjusting knob locking object lens.

The present invention only uses two level crossings, forms reflection optical system, and structure is simple especially, cost is extremely cheap, yet because the specific combination of this optical system, and the booster action of the rotatable regulating system of object lens, the eyeglass area is little, whole glasses are lightly exquisite, but see greatly as scope, the height of image space can freely be chosen, and imaging do not have distortion, do not dwindle, clear bright, glasses are worn comfortable, look and read easily.Accompanying drawing 2 is this optical path analysis figure that read glasses that look.Object lens (1) are relative with the reflecting surface of eyepiece (2), middle α in an acute angle, and obviously, the object AB that keeps flat on the table passes through reflex, and imaging is enhanced on the position of A ' B ', is arrived by the eye-observation of natural forward sight.Clockwise rotate object lens (1), also move to the direction away from the person position of visible objects AB, and imaging still can be arrived by eye-observation, has so just widened the visual range of glasses greatly, has adaptability widely.

Concrete structure of the present invention is provided by following examples and accompanying drawing thereof.

Fig. 3 is the organigram of health glasses for reading and writing provided by the invention.

Fig. 4 is the another kind of form synoptic diagram of health glasses for reading and writing.

As shown in Figure 3, (1) is object lens, and (2) are eyepiece, and (3) are picture frame, and (4) are the mirror leg, and (5) are the object lens rotation axis, and (6) for sliding to groove, (7) are adjusting knob, and (8) are the nose holder, and (9) are mirror leg folding shaft.As seen from the figure, object lens (1) are relative with the reflecting surface of eyepiece (2), and are middle in an acute angle, constitute lambda shape; Eyepiece (2) is fixed on the picture frame (3), and object lens (1) are fixed on the picture frame (3) by object lens rotation axis (5); On picture frame (3), have and slide to groove (6), can change angle between object lens (1) and the eyepiece (2) by adjusting knob (7), and the position of locking object lens (1).During use, on ear, nose holder (8) leans against on the bridge of the nose with mirror leg (4) frame, wear stable, when not using, can mirror leg (4) is folding to the center from mirror leg folding shaft (9), be received in the spectacle case and carry.The present invention is owing to wear stable, the visual field is adjustable, has purposes widely, not only can avoid because of the damage cervical vertebra of bowing, and can face upward and lean against write-read on the chair back as the official documents and correspondence health glasses for reading and writing, the flat write-read in bed that crouches, be broad masses of the people, particularly the old,weak,sick and disabled and the sick people that crouch at bed, the desirable reading writing tools of looking is provided.

As shown in Figure 4, eyepiece (2) also can directly not be fixed on the picture frame (3), but is connected with picture frame by rotation axis, so that can change the angle of eyepiece (2), the image space of observed object is had regulate leeway more freely.

Picture frame of the present invention (3), mirror leg (4) all can use metal or plastics manufacturing, object lens (1) and each eyeglass of eyepiece (2) can use the glass manufacturing, also can use the plastics manufacturing, two eyeglasses must remain in the same plane about object lens (1), the eyeglass of eyepiece (2) also must remain in the same plane, or two eyeglasses are made the monoblock level crossing that fuses.
