The sides rest on the legs with the ability to adjust the height of the tabletop. Catalog "NEW PRODUCT SUPPLEMENT" by G&S SMIRTHWAITE LTD, 1984, p. 14.

The disadvantage of this model is that when the countertop is tilted, the objects located on it (books, stationery) are in an unstable position and slide down. It is difficult for children with weak muscle tone to hold moving objects and control their position on the countertop.

The objective of the utility model is the ability to select the optimal position of the countertop necessary to develop the correct posture of the child. Ease of operation is ensured due to the possibility of arranging objects on horizontal sections of the countertop, which prevents them from slipping. This leads to a reduction in the loss of time for lifting fallen objects and thus eliminates the causes that distract the child from the learning process.

The task is achieved in that the desk, consists of a countertop with a variable angle, sidewalls with slots connected to the legs, with the possibility of adjusting the height. A bracket is attached to the countertop for lifting it from below, which moves relative to the sidewall slot and is fixed by a latch. The countertop consists of three parts: the lower fixed horizontal, the middle movable and the upper movable horizontal. The lower stationary horizontal part is attached to the sidewalls with bars. The middle movable part of the countertop is attached to two other parts with hinges. The upper movable horizontal part is equipped with a bracket with a latch, the end of which moves along the second slot in the sides, with the configuration of the slot, ensuring its translational movement in a horizontal position.

The latches are made in the form of a bolt inserted into compatible holes of the elements to be connected and a lamb screwed onto it.

The legs and sidewalls along the front and rear edges have holes for the clips.

The novelty of the utility model:

The countertop consists of three parts: the lower fixed horizontal, the middle movable and the upper movable horizontal. The presence of moving parts of the countertop allows you to change its configuration and find an individual position for each child.

The lower stationary horizontal part is attached to the sidewalls with bars. Provides reliable support for the hands and for placing objects horizontally, which does not cause them to slip.

The middle movable part of the countertop is attached to two other parts using hinges. This ensures the mobility of this part. The bracket attached from the bottom allows you to change the angle of inclination, which is convenient when working.

The upper movable horizontal part is equipped with a bracket with a latch, the end of which moves along the second slot in the sides, with

the configuration of the slot, ensuring its translational movement in a horizontal position. The upper horizontal section allows you to place objects horizontally, which prevents them from slipping and increases ease of use.

The latches are made in the form of a bolt inserted into compatible holes of the elements to be connected and a lamb screwed onto it.

The legs and sidewalls along the front and rear edges have holes for the clips. When adjusting the height of the legs, the holes are combined and the fasteners are inserted into them. This makes it easy to adjust the height of the seat for the height of the child.

The set of essential features of the utility model allows you to conveniently correctly place the child at the school desk, adjusting its individual elements in height and inclination. Separate parts of the countertop, having a horizontal position, prevent slipping of objects (books, notebooks, pens and pencils) from it. At the same time, the loss of time associated with the raising of fallen objects is reduced, the causes that distract from the learning process are eliminated. Children are less irritated, especially if the children are sick and can not independently lift the fallen objects.

The design of the utility model is presented in figure 1, figure 2

Figure 1 presents the school desk with a worktop in the initial horizontal position.

In Fig.2 the desk at the working position.

The school desk has a worktop with a variable angle. The countertop consists of three parts: the lower fixed horizontal 1, the middle movable 2 and the upper movable horizontal 3. The countertop rests on the sidewalls 4 with slots 5 and 6. The sides 4 rest on the legs 7, with the possibility of height adjustment. To the bottom of the countertop, brackets 8 and 9 are attached from below, which move relative to the slots 5 and 6 in the sidewalls 4 and are fixed by clamps 10. Lower horizontal fixed

part 1 is attached to the sidewalls with 4 bars 11. The middle movable part 2 of the tabletop is attached to the other two parts 1 and 3 with hinges 12, and moves due to the movement of the bracket 8, relative to the slot 5 of the sidewall 4. The bracket 8 is attached with the upper end to the middle movable part 2 rotatable. The upper movable horizontal part 3 is provided with a bracket 9, the end of which moves along the second slot 6 in the side walls 4. The configuration of the slot 6 provides translational movement of the upper movable horizontal part. The upper end of the bracket 9 is rigidly connected to the upper movable horizontal part 3. On the parts of the countertop can be made sides 13

The latches 10 are made in the form of a bolt inserted into the compatible holes of the connected elements and a lamb screwed onto it.

The legs 7 and sidewalls 4 along the front and rear edges have holes for the clips 10.

The countertop, sidewalls, legs are made of plywood, squared details of coniferous wood and covered with paintwork material.

The device is used as follows. The physiological and physical condition of the child is determined. The child is brought to the desk or rolled up on a special orthopedic chair. By moving the legs 7 relative to the sides 4 raise the countertop to the desired height, in accordance with the growth of the child. Unscrew the flaps of the retainers 10 brackets 8 and 9. Move the brackets along the slots 5 and 6 of the side walls 4. Choose the most convenient position of the parts of the countertop. Lie down on the inclined part 2 of the notebook and book and check to see if they are slipping off the countertop. If objects slide, the angle of inclination of part 2 is reduced. Stuff items for teaching the child on the horizontal sections of the countertops 1 and 3, so that the child can reach them if necessary. Beads 13 prevent objects from falling off the countertop, especially with spasticity of the limbs in children.

The proposed device allows you to:

- It is convenient to correctly place the child at the school desk, adjusting its individual elements in height and inclination, in order to develop the correct posture of the person.

Separate parts of the tabletop having a horizontal position prevent objects (books, notebooks, pens and pencils) from sliding off it, which creates additional conveniences.

At the same time, the loss of time associated with the raising of fallen objects is reduced, the causes that distract from the learning process are eliminated. Children are less irritated, especially if the children are sick and can not independently lift the fallen objects.
