Description

The present invention relates to teaching devices and simulators and can be used for the correct positioning of the fingers when using writing instruments in teaching children, people with impaired motor functions, writing and drawing, as well as for rehabilitation, training and restoration of lost functions due to injuries, burns and frostbite .

The problem of teaching children writing and drawing skills, as well as the restoration or development of these skills in people with congenital or acquired motor impairment due to injuries, is very relevant today.

During this process, many centers of the brain are involved: balance, attention, speech, associative memory, logical thinking, etc. On the other hand, correct, accurate writing can affect the state of a person's mental processes and his mood.

A device is known for the correct positioning of the fingers of a child’s hand when learning to write based on an elastic sleeve mounted on a writing instrument (pen) (RF patent No. 18786, published on July 10, 2001, No. 19).

The known device comprises a sleeve on which is placed a rack with a groove under the index finger for orienting the finger on the writing instrument from above. The stand is also equipped with stops - stops for the thumb and middle finger. The angle of inclination of the axis of the groove with respect to the axis of the sleeve is 30-45 ° in plan.

However, the known device provides the correct position only the index finger, while in the writing process involved three fingers - the index, thumb and middle. In addition, the device is inconvenient in operation.

For the prototype of the invention, a well-known training simulator for teaching writing was selected, including a shaped body with a guiding element for accommodating the first phalanx of the index finger with a through hole for accommodating the writing device and guiding elements for accommodating the first and partially second phalanges of the thumb and middle finger. The shaped body is equipped with a shaped emphasis under the base of the index finger, and can also be made integral with the body of the writing device (RF patent No. 43678, publ. Of January 27, 2005, No. 3).

The shaped case is made in the form of a children's toy, for example, a fish and has a through hole in the center. The known device allows for 1-2 weeks to teach a child to hold the handle correctly.

However, the known device has the following disadvantages:

- the case of the device is quite rigid, as it is made of plastisol or medical polyvinyl chloride (PVC), which has high elasticity. This does not allow to remove muscle tension from the brush in full when drawing and writing. The case has a sufficiently large volume, which, on the one hand, closes the review and the child does not see what he is writing, on the other hand, a thick case makes the pen heavier, which leads to quick fatigue of the fingers and, accordingly, of the hand. The device can be made only in the standard version, which limits its use in people of different ages and, accordingly, different arm sizes, as well as in people with various injuries to the hand and hand.

The objective of the invention is to provide physiological placement of the fingers when writing, increasing the ergonomics of the device and providing the possibility of using the simulator to a wider circle of people.

The problem is solved in that in the known simulator for the correct positioning of the fingers of the hand when learning to write, including a shaped body provided with a through hole to accommodate the writing device, and guiding elements placed on the outside of the body to accommodate the first phalanx of the index finger and for the first and partially second phalanx of the thumb and middle finger, the body is made in the form of a truncated cone, the through hole for the writing instrument is placed coaxially with the central axis of the cone, I direct These elements for the thumb, forefinger and middle finger form a triangle in cross section, the top of which is a thickening in the form of a ridge located between the guiding elements for the thumb and forefinger, the ridge is equipped with a shaped marker in the form of a ball for the correct orientation of the device on the writing instrument and placed perpendicular to the through hole, while the guide element for the thumb is placed in relation to the marker at an angle of 70-80 °, the guide element for the index finger at an angle of 45-55 ° and the guide element for the middle finger is placed at an angle of 55-65 °, and the guide elements for the fingers are made in the form of recesses with a radius for the thumb of 19-25 mm, departing from the central axis by 25-26 mm, for the index finger with a radius of 16-20 mm departing from the central axis by 22-23 mm and for the middle finger with a radius of 16-20 mm, departing from the central axis by 24-25 mm.

The proposed technical solution meets the criteria of "novelty" and "inventive step", since in the process of conducting patent information research there were no sources of scientific, technical and patent literature that would discredit the novelty of the proposed technical solution, as well as technical solutions with essential features of the proposed devices.

Figure 1 presents the proposed simulator.

Figure 2 presents the proposed simulator in operation.

Figure 3, 4, 5 schematically shows a graphical representation of the proposed simulator.

The proposed simulator for the correct positioning of the fingers in teaching writing includes a shaped body 1 (Fig. 1) equipped with a through hole 2 for accommodating a writing device. On the outer side of the body there is a guide element 3 for the first phalanx of the index finger and guide elements for the first and partially second phalanges of the thumb and middle finger, respectively (not shown). Shaped housing 1 is made in the form of a truncated cone 4 (figure 3). The through hole 2 for the writing instrument is placed coaxially with the central axis of the cone. The guide elements for the thumb 4, index and middle fingers form a triangle 5 in cross section, the top of which is a ridge-shaped bulge located between the guide elements for the thumb 4 and index finger. The comb is equipped with a shaped marker 6 (figure 4), made in the form of a ball for the correct orientation of the device on the writing instrument. The guide element for the thumb 4 (Fig. 5) is placed with respect to the shaped marker 6 at an angle of 70-80 °, the guide element for the index finger 7 at an angle of 45-55 ° and the guide element for the middle finger 8 is placed at an angle of 55-65 °. The guide elements for the fingers are made in the form of a recess with a radius for the thumb of 19-25 mm departing from the central axis by 25-26 mm, for the index finger with a radius of 16-20 mm departing from the central axis by 22-23 mm and for the middle finger with with a radius of 16-20 mm, departing from the central axis by 24-25 mm. The length of the truncated cone is 23 mm, the diameter at the base is 18-20 mm, the diameter of the apex is 13-15 mm. The diameter of the through hole is 8-9 mm.

The proposed simulator is used as follows.

A writing instrument (pen, pencil) is inserted into the through hole. Shaped marker 6 should be located on top of the writing instrument between the thumb and forefinger. The thumb, index and middle fingers are located in the recesses 4, 7, and 8 (figure 2). What follows is writing or drawing.

The present invention allows to obtain the following positive effect. The implementation of the guide elements at a certain angle to the shaped marker of the simulator (the guide element for the thumb is placed relative to the marker, directed at an angle of 70-80 °, the element for the index finger at an angle of 45-55 ° and the guide element for the middle finger is placed at an angle of 55 -65 °) and the execution of the guiding elements at a certain distance from the central axis of the simulator (the guiding element for the thumb is placed departing from the central axis by 25-26 mm, for the index finger, departing from the central axis by 22- 23 mm and for the middle finger, departing from the central axis by 24-25 mm) corresponds to the correct and physiological arrangement of the fingers on the writing instrument. In addition, the fingers are conveniently and freely placed in guide elements made in the form of recesses, the radius of curvature of which corresponds to the anatomical size of the fingers, depending on the age and, accordingly, the size of the fingers. The simulator makes a person hold the writing instrument correctly, while the hand does not strain and does not “clamp”. The marker does not block the writing field of vision for the person writing. The simulator is made of silicone - a light and durable material. The weight of the exercise machine makes 5 gr. In the manufacture of a simulator in mirror image it can be used by “left-handed people”. The simulator allows you to quickly and effortlessly teach children how to hold a writing or drawing instrument. It will allow adults with impaired motor functions (Cerebral Palsy) to learn writing and drawing and restore these functions to people who for some reason have lost them. The simulator can be produced both in mass production and individually.
