Description

The utility model relates to the field of orthopedics and can be used to form and maintain correct posture, prevent and treat spinal curvature, as well as maintain visual acuity, prevent myopia and other eye diseases.

An analogue of the proposed utility model is the "Posture Corrector" [RF Patent for Utility Model No. 66672, published September 27, 2007, Bulletin No. 27], comprising a belt made of elastic material with a spinal column vertically mounted on it and two adjustable from each other diverging from its top along the length by means of buckles with shoulder straps provided with fixing elements at the ends. However, this design only partially corrects posture (you can lean to the right, left, forward), and does not solve the problem of maintaining vision at all, since the physiologically necessary distance (30-35 cm) from the table to the eyes is not observed during work.

The prototype of the proposed utility model is the utility model "A simulator for the formation of correct posture and preservation of visual acuity of younger students" [RF Patent for utility model No. 110636, published November 27, 2011, bulletin No. 33] containing an elastic belt with pockets and Velcro for tightening ; two spinal racks with bent upper ends, the lower ends of the racks inserted into the pockets, and the upper ends wearing fixing elements in the form of T-shaped bushings in the horizontal holes of which a tubular, plastic crossbar is inserted with the possibility of rotation around its axis. In the middle of the crossbar, a plastic rod is rigidly fixed, on the other end of which a soft roller is rigidly fixed to support the chin.

The disadvantage of the prototype is the lack of full, rigid fixation of the simulator on the student’s body in accordance with its anatomical features, as well as the complexity of the design of the simulator and its production technology.

The objective of the proposed utility model is to improve the simulator for the formation of correct posture and preservation of visual acuity of younger schoolchildren, which allows to simplify its design, improve ease of use and manufacturability.

The technical result of the utility model is the provision of rigid fixation of the simulator on the student’s body, due to a tighter fit and the possibility of fitting its size, taking into account the anatomical dimensions. This allows you to form the correct posture of the student, maintain his visual acuity and helps prevent various diseases of the spine and eyes.

The technical result is achieved in that the simulator containing a belt made of elastic material with vertically mounted on it with two height adjustable spinal racks with rounded upper ends to grip the pupil’s shoulder girdle, connected using locking elements with a mechanism for fixing the chin, which consists from a rod, at one end of which a soft roller is rigidly fixed to support the chin, and the other end is rigidly connected to a horizontal bar fixed with the help of fixing elements with the possibility of rotation around its axis and movement along the bent ends of the spinal racks, while the spinal racks are made of metal-plastic tape with a width of 15-20 mm and a thickness of 1.5-2 mm, and the mechanism for fixing the chin consists of a rod and a horizontal crossbeam made in the form of a tube made of matter with tongues and Velcro on both ends, which cover the bent ends of the spinal racks, and the rod is made of rigid wire folded in half, and the lower part of the rod is divorced by the ends of halves of the wire in one line and inserted into the horizontal cross-section, with the possibility of rotation around the axis, the middle part of the rod is fixed in a hard plastic case, the upper part is curved ellipsoidly, and the soft roller is made in the form of a foam tube with a cut in the middle, worn on the upper part of the rod, with this elastic belt has two movable pockets made of matter in the form of two rings one on the other with Velcro, an elastic belt is threaded into large rings, and the lower ends of the spinal racks are inserted into small rings, which o provides adjustment of the simulator according to the height and width of the back of the student.

In contrast to the prototype, the proposed simulator is more convenient to use, more technologically advanced to manufacture, easier and cheaper at cost. In addition, he has a greater number of adjustments for the dimensions of the student, namely:

- adjusting the horizontal bar along its length, taking into account the width of the student’s chest, by changing the length of the tongues with Velcro on both sides of the tube;

- performing a fixed up-down movement of the mechanism for fixing the chin, which allows you to strictly maintain the physiologically necessary distance of 30-35 cm from the table to the pupil’s eyes;

- thanks to the spinal racks made of metal-plastic tapes, it is possible to bend their upper ends, which will provide the possibility of a snug fit to the student's body, taking into account its anatomical features;

- the possibility of lowering or raising the spinal racks in the small rings of the pockets, provides adjustment of the simulator taking into account the growth of the student;

- the movement of large rings on the elastic belt adjusts the position of the spinal racks along the width of the back;

- Velcro fasteners at the ends of the elastic belt, tightening it at the waist according to the dimensions of the student.

In FIG. 1 shows a general view of the simulator for the formation of proper posture and preservation of visual acuity of younger students. It consists of: two spinal racks 1, made of metal-plastic tape, with a width of 15-20 mm and a thickness of 1.5-2 mm with curved and rounded upper ends to surround the shoulder girdle; a mechanism for fixing the chin (shown in Fig. 2), mounted on spinal racks with support on rubber rings 2, dressed on the ends of the spinal racks; and elastic belt 3 with Velcro 4; two movable pockets 5, made of matter in the form of two rings (one in the other) with Velcro and shown in Fig 3, moreover, elastic rings 3 are threaded into large rings 14, and the lower ends of the spinal racks 1 are inserted into small 15.

In FIG. 2 shows a mechanism for fixing the chin. It consists of: a rod 6 and a horizontal bar 7 made of matter in the form of a tube with a cut in the middle 8. with tongues 9 and Velcro 10 at both ends. The tongues cover the bent ends of the two spinal racks, and the Velcro straps provide for the adjustment of the length of the horizontal bar 7, depending on the width of the chest of the student. The horizontal bar can move up and down along the spinal racks, having additional support on the rubber rings 2, worn on the ends of the spinal racks (see Fig. 1). Rod 6 is made of a piece of rigid wire with a diameter of 3 mm folded in half, the lower part of which is divorced by the ends of the wire in one line and inserted into the cut 8 of the horizontal crossbar 7 with support on the lower, inner wall of the tube, with the possibility of turning around about its axis . The middle part of the rod is placed in a hard plastic case, consisting of two halves 11. The upper part of the rod 6 is curved ellipsoidly. The soft roller 12 is made in the form of a foam tube with a cut 13 in the middle and is worn on the upper part of the rod 6.

In FIG. 3 shows one of the two movable pockets 5 on the elastic waist 3 (see Fig. 1). Pockets are made of matter in the form of two rings, one in the other with Velcro (not shown). At the same time, elastic belt 3 is threaded into large rings 14, and into small rings 15, the lower ends of the spinal racks are inserted. This allows the simulator to be adjusted for the height and width of the student’s back. Small rings 15 are located on the outside of the elastic belt 3. Thanks to the Velcro 4 located on the elastic belt 3, it is fixed by the girth of the student.

The simulator is used as follows: first, the spinal racks 1 are put on the shoulders, then the student tightens the elastic belt 3 with Velcro 4. To wear or remove the simulator, it takes no more than 3 seconds.

It is advisable that all students in the class have their own simulator. In the first lesson, wearing a simulator, students sit at their desks (tables). The teacher asks everyone to put their left hand upright on their elbows. With your right hand, turning the shaft 6 towards you and raising or lowering the horizontal bar 7 together with the rings 2, set it so that when you support the chin on the foam tube 12, the extended fingers of the left hand are at the temple (or the thumb was at eye level) . This corresponds to a physiologically sound norm of 30-35 cm from the table to the eyes. In place of the rubber rings 2, students make a mark on the spinal racks 1, so that at any time they can then set the desired height of the horizontal crossbar themselves 7. Schoolchildren carry out all other simulator adjustments for the individual sizes of their bodies on their own.

The teacher, leading the lesson, physically cannot follow and correct the position of each student, and with the use of simulators he does not need to worry about it.

Thus, throughout the lesson, students observe correct posture, since they cannot stoop and lean to the side, even the cervical vertebrae do not bend, the neck muscles do not squeeze the blood vessels and the blood flows normally to the head, and due to the fixation of the chin the required distance is strictly maintained 30-35 cm from the table to the eyes. Coming out to answer to the board, the student simply lowers the rod 6 down. At breaks, you can remove the simulator and hang it on the back of the chair.

After class, students, having disassembled the simulator, put it in a backpack or a special case made of cloth and take it home, for further use at home when doing homework, reading, and working at the computer.

It is very important to use the simulator both at school and at home, as this will allow younger students to form a correct posture, to avoid many diseases, such as scoliosis, etc., and also to maintain visual acuity, preventing the development of myopia and other eye diseases, while preserving the acquired dynamic stereotype for life at work at a table or at a desk.

The simulator is simple in design, technologically advanced to manufacture, safe and easy, and also has a low cost. It can be used both in the lower grades of schools and kindergarten preparatory groups, as well as in children's medical institutions and specialized rehabilitation centers.

The production of the simulator can be mastered by many firms, enterprises and companies.
