Abstract

The utility model relates to a reading-writing board which is composed of a movable board, a main board and supporting feet of the main board. The main board and the movable board are made of boards. The supporting feet can arbitrarily alter the length, and the movable board is attached on the main board. The key point is that the main board is an iron board. The movable plate is a non-iron board which is provided with a magnet at the central position. The main board is regulated during use, the proper inclination angle is selected, and a book is placed under an elastic pressing rope on the movable board. Two eyes view horizontally and a body sits up to complete reading and writing work, therefore, the habit of bending waist can be changed, and the distance of normally reading and writing can be ensured. Thus, the utility model has the effects of correcting bent waists and protecting the vision when the reading-writing board is used for a long time.

Description

Read-write board

The utility model belongs to a kind of cultural goods, and rectifying sitting posture of student or the incorrect custom of some reading and writing postures are had better action, thereby reaches the effect of protection eyes and the normal development of assurance health.

The common desk or the panel of desk are all horizontal, like this, the people of reading and writing or office often forms both hands and pounces on custom on desktop, in the course of time, not only cause hypometropia, severe patient also is accompanied by trunk flexural deformation, and is just more outstanding for the heavy students in middle and primary schools' that are in the body development growth stage again of learning tasks influence.For this reason, existing manyly be used to change children's study and learning and pounce on the table the articles for use manufacturing technology of this bad habit and come out, can have mandatory effect owing to majority, user's utmost point sense discomfort.In case the disengaging condition is just recovered bad habit again; So difficulty is formed correct sitting posture and read-write posture, do not reach the purpose of correcting fully.As be stuck in the Support for preventing myopia of pouncing on before a kind of children of preventing on the desk edge, and exactly when pouncing on before the student, support holds out against at its chest, and upper body can not be pounced on the desktop and achieve the goal.So be passive rectification, and long-term the use, may be influential to the normal development of child's chest.And, use also normal sense discomfort.Also there are the reading stand one class articles for use that adopt some relative desktops can change the angle of inclination to increase visual effect, the people is felt comfortably cool, also can reach the effect of vision protection.But only limit to the reading aspect, incorrect rectification just can not effectively solve for writing posture; Especially for the people who is engaged in office's secretarial work for a long time, no matter be the Support for preventing myopia that clamps on the desktop, the reading stand that still can change the inclination angle all is not suitable for, and uses also inconvenient.

The purpose of this utility model is exactly to disclose a kind of portable plate that shifted one's position arbitrarily on mainboard by the mainboard that can change the angle of inclination and energy, that be used to fold up books to constitute, and reaches the read-write board that allows the user rectify sitting posture and vision protection naturally.

The scheme that realizes above-mentioned purpose is as follows:

This read-write board is made of portable plate and mainboard and feet thereof.Mainboard and portable plate are all used board making.Mainboard and feet are installed on the quadra, and feet can change length arbitrarily, and portable plate is attached on the mainboard; Key is that mainboard is an irony sheet material, and portable plate is the non iron sheet material that a center position is equipped with magnet.

Further scheme is the guide rail that portable plate dual-side edge is fixed with the band chute, and the bottom is connected with elastic force and presses rope along the books supporting plate is housed between the chute of two guide rails.Press rope two ends system that the bail that slides that can slide in the chute of guide rail is arranged.

Press such scheme, make framework earlier, install feet, again in the positive punching of framework, with the solid good mainboard of screw dress; Portable plate with plastics or wooden boards all can, a dress solid block permanent magnet in heart position is so just made a read-write board therein.During use, it is put on desk, regulates the height of feet, change the inclination angle of mainboard and desktop, until sit up straight look squarely also feel comfortably cool till.Books are placed under the stretch cord on the portable plate compress.Suitably the position of moving active plate on mainboard feels that easy-to-read ends with writing.

The utility model has the advantages that the mainboard gradient is adjustable, finish by magnetic function the displacement of portable plate on mainboard and location, and books are compressed by stretch cord on portable plate.Simple in structure, stability is good, and in reading and writing process, the conscious active of decapacitation also needn't be used the hand books outside sitting up straight; Even action of writing, only the hand that need hold a pen moves on books and gets final product.So bad habit of having avoided both hands to pounce on causing on the table of bending over and affecting one's power of vision.

Fig. 3, portable plate structure schematic diagram;

Fig. 4, slide bail and stretch cord connected mode schematic diagram;

Fig. 5, portable plate Facad structure schematic diagram.

Below in conjunction with accompanying drawing,, scheme of the present utility model is specified as an embodiment.

With reference to Fig. 1,2, earlier make framework 2 with angle bar or aluminium alloy extrusions, with install feet 8 and fixedly the connecting hole of mainboard 4 hold successfully; Be screwed the smooth iron plate of upper surface as mainboard 4 in framework 2 fronts, install feet 8 at its back side.

With reference to Fig. 1,3,5, portable plate 5 adopts wooden or plastic plate is made, and has been screwed two in its both sides and has vertically slided guide rail 6; Slide the guide rail aluminium alloy extrusions.A strip supporting plate 7 is installed in the portable plate lower edge, is used to prevent that books from falling, and there is a plate washer 3 that the panel 13 of two guide rails 6 and portable plate is linked together the upper edge.The back side center position of portable plate 5 is installed the disc permanent magnet 9 that similar megaphone is used.Just made portable plate.

With reference to Fig. 1,4,5, the two ends of stretch cord 1 bind respectively that an energy slides in guide rail chute 11 slides bail 10.The head of a nail part of bail is in the form of annular discs, favourablely slides in chute 11; Its ailhead top is sheet shape, has the hole of fastening stretch cord.The two ends of the stretch cord of getting ready 1 fasten slide bail 10 well admittedly after, two bails are slipped into the head of a nail of bail the chute 11 from guide rail 6 upper oral parts 12, the end opening of guide rail is then sealed by books supporting plate 7.The length of stretch cord 1 selected, should make it be installed in 6 on two guide rails has the elastic force effect can.

The read-write board of making in a manner described places it on the desk, along drawing back feet perpendicular to the direction of mainboard face, changes its length, regulates the gradient between mainboard and desktop, sees under the state of looking squarely books feel comfortably cool and ends sitting up straight.Books are sandwiched under the stretch cord on the portable plate, and the suitable position of moving active plate on mainboard read and write and all feel the convenient standard that is as required.Read like this and write all needn't hand by books, only sit up straight with two at eye level, just have comfort.Therefore, the long-term use has nature to correct the effect of upper body part and eyesight; Avoid both hands to pounce on desktop, cause the consequence of crooked hunchback and hypometropia.Also overcome the harmful effect that has positively-acting reading stand that health is produced.
