Description

The present invention relates to medical technology, more specifically to devices for the prevention and formation of correct posture when working at a desk and to a method of its use for the prevention of postural disorders, in particular in children at school and at home.

Children at school age, especially at primary school age, are very mobile, but quickly get tired, and long-term studies at the desk lead to various types of posture disorders. It is known that the age of 7-17 years is the most important for the correct formation of posture. Currently, many devices are known for correcting and shaping correct posture, used when working at a writing desk. They can be conditionally classified into two groups. The first includes devices that fix the position of the user on the chair. These include, for example, the devices described in patents RU No. 2546086 (publ. 10.04.2015), CN No. 2845772 (publ. 13.12.2006), CN No. 203370001 (publ. 01.01.2014), CN No. 2642268 (publ. . 22.09.2004), US 20050194830 (publ. 08.09.2005). The second group includes devices that fix the position of the user relative to the desk. These include, for example, devices under the patents RU No. 59405 (published on December 27, 2006), RU No. 175310 (published on November 29, 2017), RU No. 105159 (published on June 10, 2011), KR No. 20150042977 (published on April 22 2015), KR No. 101449665 (publ. 10/13/2013), CN No. 2087909 (publ. 11/06/1991), CN No. 2198813 (publ. 05/31/1995), CN2200975 (publ. 06/21/1995). A common drawback of all the listed devices is their lack of functionality. They are designed to prevent any one deviation in posture. For example, some of them allow you to sit upright and prevent excessive bending forward (stoop), but do not take into account that the child can lean to the side or lower one shoulder (RU # 59405, RU # 105159, CN # 2642268, CN # 2087909, CN # 2198813), others, on the contrary, do not allow you to bend from side to side (RU No. 175310), but do not prevent stooping, others do not allow you to press your chest against the table, but do not prevent stooping and bending to the side (KR No. 20150042977, KR No. 101449665) ... It is known that while working at a desk, the back should be straight and pressed against the back of the chair. There should be a distance between the chest and the table, but it should not be large. This distance is determined by the width of the palm. The forearms should lie completely symmetrically on the table, the shoulders should be at the same level. The distance from the eyes to the book should be 30-35 cm. Known devices do not provide all these conditions. The disadvantage of devices according to patents RU No. 59405, CN No. 2642268 is also the impossibility of adjusting for changes in the height of the child, which also reduces their functionality. Some of the listed devices are complex and inconvenient to use.

Thus, the task is to create a device for the prevention and formation of correct posture, which would have greater functionality and versatility in comparison with known devices, as well as a method of using such a device.

The technical result consists in creating a device for the prevention and formation of correct posture, which would have greater functionality and versatility in comparison with known devices, as well as a method of using such a device.

To achieve the specified technical result, the device for the prevention and formation of correct posture "Posture Assistant" contains two plates - a horizontal one, attached to the table top, and a vertical one, mated with the edge of the table top, and the plates are connected by a groove into a groove, the vertical plate contains several grooves for connection with horizontal plate made with a step of 2-5 cm, the distance between the edge of the horizontal plate facing the user and the groove for connection with the vertical plate is equal to the width of the user's palm (from 6 cm for a six-year-old child and up to 10 cm for an eighteen-year-old teenager according to the size tables), the width of the plates is equal to the width of the user's body; the device additionally contains a latch attached to the back of the chair and containing a fastening assembly and associated central and two side belts provided with means for adjusting the length. In the particular case of the device, the horizontal plate can also have more than one groove, while the distance between its grooves is 2-4 cm. The horizontal plate can be attached to the tabletop using fasteners (for example, bolted connections, screws) or using magnets. Plates can be made of metal, plastic, plywood, hardboard, wood. Preferably, the retainer belts are made of elastic material - leather, rubber, textile. Preferably, the attachment point is made in the form of a buckle. It is advisable to make the means for adjusting the length of the side straps of the retainer in the form of buckles, Velcro tape, buttons, magnetic fasteners, fastex buckles, button fasteners.

A horizontal plate attached to the tabletop, in particular with fasteners or with magnets (other known fastening methods can be used), limits the distance between the user's chest and the tabletop and at the same time serves to install the vertical plate. At the same time, the recommended distance between the user's chest and the palm-width tabletop (6-10 cm) is maintained. In a particular case, this distance can be adjusted depending on the width of the user's palm by making several grooves in the horizontal plate with a step of 2-4 cm. The vertical plate, mating with the edge of the tabletop, is installed with a groove in the groove of the horizontal plate and limits the position of the user's hands on the tabletop. due to the selected width of the plates across the width of the user's body, and also limits the position of the user's head above the tabletop. At the same time, due to the selection of the installation height of the vertical plate above the table top (selection of the groove for the installation of the vertical plate), the user's gaze falls on the table surface visible to him behind the vertical plate (on a notebook or book) in such a way that a distance of at least 30-35 cm from the user's eyes to a book or notebook. At the same time, due to the fact that the vertical plate has several grooves made with a step of 2-5 cm, it is possible to adjust the device depending on the height and, accordingly, the age of the user. The distance from the top edge of the vertical plate to its groove can be determined by calculation. The calculation is made as follows. The length of the leg of a right-angled triangle, opposite to the angle at which the user's gaze falls on the table surface, is determined, while the length of the adjacent leg is equal to the distance to the edge of the tabletop, and the hypotenuse lies on the user's line of sight. When the distance between the grooves is less than 2 cm, the strength of the plates deteriorates. If the distance between the grooves of the vertical plate is more than 5 cm, the possibility of adjusting the device for different heights and ages of the child is limited. If the distance between the grooves of the horizontal plate is more than 4 cm, the possibility of adjusting the device for different heights and ages of the child is also limited, since the difference, for example, between the palm width of a six-year-old child and an eighteen-year-old teenager is just 4 cm. For the convenience of using the device, it is advisable to make inscriptions next to the grooves about the height or age they correspond to.

The presence of a retainer attached to the back of the chair allows the user's back to be locked in the correct position. In this case, the central strap is used to attach to the back of the chair, and the side straps are used to fix the user's shoulders. This prevents slouching when working at a table, and also prevents one shoulder from dropping or lifting or "twisting" the user's body. The attachment point, in the special case in the form of a buckle, allows you to fix and adjust the position of the latch on the back of the chair, as well as use it on different chairs. The means for adjusting the length of the side straps of the retainer, in the particular case in the form of buckles, Velcro straps, buttons, magnetic fasteners and the like, make it possible to adjust their tension for a particular user. At the same time, the elasticity of the material of the side straps of the retainer gives the user a certain freedom. All of the above made it possible to create a device for the prevention and formation of correct posture, which has greater functionality compared to known devices, since it is intended for users of different heights and ages, allows you to correctly position your hands, head and body when working at the table, contributes to the formation and prevention correct posture and prevents myopia. The device is also easy to manufacture and use.

A method of using the device for the prevention and formation of correct posture "Posture Assistant" is also proposed, in which:

- attach the horizontal plate to the table top, providing a distance between the edge of the horizontal plate facing the user and the groove for connection with the vertical plate equal to the width of the user's palm (6-10 cm);

- install the vertical plate with a groove in the groove of the horizontal plate, while ensuring the conjugation of the vertical plate with the edge of the table top;

- attach the retainer to the back of the chair using a central strap and an attachment point, provide a tight fit with the lateral straps of the retainer of the user's shoulders due to their length adjustment means and the straight position of the user's back;

- the user is seated close to the horizontal plate attached to the table top, the user's hands are placed on the table;

- when the user's height changes, the height of the vertical plate above the table top is adjusted due to the possibility of its installation in the horizontal plate by one of several slots of the vertical plate, made with a step of 2-5 cm;

- in a particular case, the distance between the user's chest and the tabletop is adjusted by installing a vertical plate in one of several grooves in the horizontal plate, made in increments of 2-4 cm.

The device and its use can be explained with the following example.

A prototype device has been used by the author at home since the age of 11. The horizontal and vertical plates are made of hardboard, the same size, 25x25 cm. It has been noticed that the width of the body (body) in children and adolescents at the age of 6-18 does not change as much as the height. Therefore, a change in the width of the user's body and, accordingly, a change in the width of the plates can be neglected. In this particular example, the width of the plates of 25 cm corresponds to the width of the author's body, this width allows you to freely place your hands on the tabletop behind the device. Both plates have two identical grooves for connecting groove to groove with a pitch of 5 cm. Thus, the plates are interchangeable. The horizontal plate was attached to the table top, while maintaining the distance between the edge of the horizontal plate facing the user and the groove for connecting to the vertical plate equal to the width of the palm, in this particular example 5 cm.This distance also corresponds to the distance from the edge of the table top to the user's chest. A vertical plate was inserted into the groove of the horizontal plate, while it was pressed against the edge of the tabletop, and its height, due to the use of one of its grooves, was chosen so that the user's gaze fell on the part of the tabletop surface visible behind the vertical plate at an angle of no more than 30 °. The straight position of the back on the chair was ensured by a brace. At the same time, the author notes that the side straps did not allow him to lean forward and stoop, raise or lower his shoulders. The horizontal plate did not allow to press against the table top, the vertical plate did not allow the head to be lowered too much. At the same time, the author also notes that he did not experience any inconvenience when using the device when writing or reading, the author was less tired when doing homework. According to the author, the task of parents to preserve the child's health has also become easier, now they do not need to repeat many times “sit correctly”, “raise your head”, “do not bend over” when the child is doing homework. The Posture Assistant helps parents not to make themselves and their child nervous. The device is easy to carry and install and can be used both at home and at school. After starting to use the device, the author did not experience any deterioration in posture.

An example of using the device. A 6-year-old child was diagnosed with grade 1 infantile idiopathic scoliosis. To correct the posture, physiotherapy exercises were prescribed in the exercise therapy room. No positive dynamics was observed. At the age of 11, the child, in addition to exercise therapy, began to use the "Posture Assistant". The device has been in use for 5 years to date. According to the conclusion of the pediatric orthopedist from 07/12/2019, there is an improvement in posture.
