Parents are also worried about their vision problems, and various vision protection. Institutions and vision care products are constantly emerging. The survey found that the formation of myopia is mainly caused by reading books at close range. Therefore, keeping the distance between the eyes and the reading materials during reading and writing is very important for preventing myopia.

The existing prevention of myopia products is inconvenient to use, such as an anti-myopia frame, designed to correct the student's writing posture, so that students are far away from the book when writing, but the product needs to be fixed at the desk at the chest when using the product. In order to prevent the body from leaning forward, the defect of the product is relatively large, and it is convex on the chest table. The restriction affects the student's chest activity space, so that the student's body freedom is reduced, and must be installed at the table. It can't be used when you leave the table, so you can't protect your eyesight at any time because of the limited environment. You can only use limited protection for writing. In real life, the impact on children's vision is not only close to the book when writing, but also too close to the desk to read, especially when playing electronic products such as mobile phones for a long time. Serious damage, parents and teachers repeatedly reminded children to keep writing and reading distance can not effectively avoid this situation, the children are writing and looking at the book is close to the book. It is not as effective as the previous effective protection. Only a comprehensive prevention can protect eyesight. If there is a product that is easy to use, it will help students and books maintain a healthy distance and effectively prevent close writing and Reading, and without the limitations of the use of the occasion, small size and light to carry with you, will certainly be able to better prevent the occurrence of myopia from the source, in addition, myopia is a national problem, the product price can be low to benefit the whole people.

Big problem

In use, only the arm bending degree is mandatory, and there is no influence on the arm extension, so that the arm is in a semi-controlled state, so that the arm curvature can be regulated without affecting the free extension of the arm, and the user can write for a long time. When the arm is sore, the arm has a certain stretching space. The user can wear only one writing arm as needed, and the other arm can flex normally and flex to take the required school supplies and scratching during the learning process;

The invention can also influence the folding angle of the limited-angle positioning body plate and adjust the arm bending angle by setting different abutting bodies, so that the high and low fat and different people can adjust to the arm angle suitable for oneself, which also makes the product Production becomes convenient, an adjustable product can meet different people, and it is not necessary to separately produce corresponding sizes for different groups of people;

The restraint strap is designed to adjust the tightness of the wear when the thickness of the clothes is increased or decreased in spring, summer, autumn and winter;

detailed description

A posture correcting protector of the present invention and its application will be described in more detail below with reference to the accompanying drawings and by way of specific embodiments.

The first embodiment of the present invention provides a posture correction device, which is composed of a limited angle positioning body and a binding body, and the limited angle positioning body is composed of the first plate 3 and the first embodiment. The two plates 4 are hinged, and the upper surface of the hinge portion of the first plate 3 protrudes with a supporting body 5 for supporting between the first and second plates, and the first plate 3 is connected at one side ( Can be glued / stitched / buckled, etc.) The binding strap made of soft material 2 (the strap can be connected by: setting a Velcro on the bottom of the first panel, and binding the strap with the Velcro on the surface The upper plate is bonded to the first plate, and the binding band is used for binding the fixed product. There are various connection methods here only one or two), (the optimal connection mode of the binding band is only the first in FIG. 1) A strap is provided on the side of the plate 3 to bind a plate of the angle-limiting body to the upper arm of the elbow. This arrangement has the advantage of eliminating the cumbersome wearing of the two straps, simplifying the wearing process, and forearm skin. The discomfort is more obvious after the sensitive restraint, and the plate at the forearm position is not tied with the binding band. It does not affect the stacking of the product. When the forearm is extended, because of the flexibility of the hinged shaft and the gravity of the plate itself, the second plate 4 attached to the forearm will move with the forearm even if there is no binding band binding. The tether band 2 has a Velcro surface 72 at one end, and the Velcro surface 71 at the other end of the tether band 2, and the tether band 2 surrounds the wearing body 1 (elbow arm) to form the first plate 3 and the second plate 4. The angle-limiting positioning system is attached to the inner elbow of the elbow arm. After wearing, the first plate 3 and the second plate 4 are respectively located at the upper arm and the lower arm of the elbow arm.

When the wearer bends the arm with the vision protector, the elbow bends to drive the first plate 3 and the second plate 4 to fold each other, and when folded to the abutment body 5 against the second plate 4, the first plate The sheet 3 and the second sheet 4 are folded due to the abutment of the abutting body 5, so that the elbow arm cannot continue to bend, and the arm is in a healthy and appropriate camber position (because of the wearer's fat and thin body and body and body proportions and even The difference between the height of the seat and the table, the angle of the arm that meets the comfort of each person when writing or holding the book will be different. In actual production, the support body 5 of different lengths is set, and the support body 5 and the plate are adjusted on the plate. The angle between the sheets or the caps of different thicknesses on the top of the supporting body to adjust the contact distance between the supporting body and the sheet can affect the angle of the first and second sheets after folding, and the healthy viewing distance The angle of the arm is about 60-140 degrees. At this camber, the hand-held reading of the upper arm or the distance between the pen and the eye is a suitable healthy line of sight, which is not easy to damage the vision.

In addition, when wearing the vision protector, the limited-angle positioning body only limits the bending of the arm, but does not limit the stretching of the arm, and protects the visual force while still allowing the arm to have a space for stretching. In order to let Pei The wearer has better freedom of movement when writing, just wear the eye protector on the writing arm and the other arm can be bent normally. In addition, taking the right hand writing as an example, some people will write on the left arm side of the head. At this time, the elbow angle of the eye protector remains unchanged, but the forearm will turn left as the human body turns to the left. Side rolling, (Fig. 2) A contact type alarm 8 is provided on the second plate 4 of the vision protector, and the inside of the tether band 2 (corresponding to a position slightly below the inner side of the elbow forearm) is touched by the arm. Press on the table and give a vibrating/audible warning to remind the wearer to correct the sitting position. In practical applications, the alarm can be placed on the right inner side of the restraint band 2 (inside the left arm) or the left inner side of the restraint band 2 (inside the right arm) for people who are writing left and right. The bottom surface of the gusset of the angle-limiting body can be curved to accommodate the curvature of the arm.
