Growing table with your own hands. How to make a children's table desk. Models with smooth adjustment mechanisms are more convenient to use. With their help, you can organize a workplace in any corner of the apartment. The table-storage system has an original design
Like a desk that is main part any interior educational institution. Also, the desk can be usefully implemented at home, which is why it was decided to make a desk for children with their own hands. In this article I will tell you how the author made an age-appropriate small desk with his own hands and a comfortable chair, which makes it easy to flip through picture books, draw, sculpt from plasticine or lay out toys. Before manufacturing, we need to decide on the materials needed for this.
In order to assemble this homemade product, we need:
* Piano loops 50 cm long.
* Con-firms.
* Self-tapping screws.
*Sandpaper.
*Metal corners.
*Sawing furniture board from pine, for a desk according to scheme 1, and for a chair according to scheme number 2.
Here are all the materials ready.
You will also need tools:
* Electric jigsaw.
* Screwdriver.
*Grinder to facilitate grinding work.
And this is how the drawing of our future desk looks like, since making details with dimensions taken from the head will not only be wrong, but also not accurate.
Step one.
First of all, you need to assemble the desk, and only then the chair, so we gradually proceed to the exciting assembly process. As usual everything wooden details should have the least roughness, which in other words just be encrypted. Sanding is best grinding machine or with the help of a grinder, if it is not there, then you can use ordinary sandpaper. It should be processed with sandpaper, first coarse P40, then medium P120 and smaller P220. We correct sharp corners with a jigsaw, thereby rounding them. After grinding, it is necessary to cut out semi-circular recesses in the legs, this is done so that the child who will sit at the desk does not experience discomfort, and also so that when turning to the sides, the knees do not rest.
Step two.
Now you need to attach the legs to the bottom of the box, we do this with the help of mats, it is better to screw them with a screwdriver into the holes that need to be made in advance, the diameter of which is slightly smaller. We lower the bottom 8 cm lower than the edge of each of the legs, as shown in the figure according to scheme 3. After that, we fix the front wall of the box, given that its upper edge should be level with the legs, so that the box turns out to be almost perfect and even. Armed with a screwdriver, we attach the back wall of the desk to them with screws, the resulting protrusion should be several centimeters higher than the edges of the legs themselves.
Step three.
A desk without a tabletop is not a desk, so we will attach it now, but we need a piano hinge for this, it must be fixed so that its free movement can allow the tabletop to be raised and lowered without any difficulty and sticking, and also so that it the surface when closing had a flat surface, for better contact and evenness. The result is a medium-sized drawer under the tabletop, where you can store things such as sketchbooks, coloring books, supplies, and many other little things.
It is also worth considering that the protruding edge of the rear wall of the desk prevents the pen and the like from rolling and falling on the floor, which can be left on the tabletop without fear that the pen will roll off somewhere when the lid is raised, as in photo 2.
Step four.
This is how we got to the creation of a chair, we also make it out of wood, after which we fix its legs at an angle to the seat, which we fasten with a trapezoidal support board, at one time it must be inserted in the middle between them, as shown in diagram 4. To to strengthen the structure, knowing that children love to swing on a chair, all its parts at the joints must be fixed using metal corners that can be borrowed from furniture, see photo 3. We also fasten the back, as shown in photo 4. You can increase stability by cutting on the legs in the supporting part there are semicircular recesses. Prematurely cut out a groove for the backrest in the seat, which is shown in photo 5. The latter was rounded off in the upper part and a heart-shaped hole was cut so that the chair is easier to carry, this shape is easiest to cut with a jigsaw according to a pre-drawn pattern.
Party drawing. Assembly diagram and detailed description home desk which is adjusted to the height of the child.
The design of the school desk allows you to adjust the height from 575 to 775 mm and the angle of the table top from 0 to 10 degrees, taking into account the anthropometric data of the human figure (see article). Height adjustment is made in steps of 50 mm. The table top angle is adjusted in 5 degree increments. This setting allows you to provide comfortable conditions during the study and classes of the child. As the child grows, so does our desk.
The school desk is made of wooden knots and chipboard. Let's prepare necessary material and kit. We start assembly.
IN wooden base we mill two grooves for the guides.
We insert guides into the grooves on the PVA glue. On the inside of the guides, we mill grooves 10 mm deep and 10 mm wide. The length of the grooves is selected in such a way that at the smallest height of the desk, they would be the lower stop of the lifting mechanism.
Assembling the base structure. We drill through holes in the transverse rails and fasten the side walls of the shelf.
We fix the bottom of the shelf and the footrest.
Set up the mechanism for lifting the tabletop. The guides should slide easily into the grooves. In the guides, we drill four through holes with a diameter of 20 mm in increments of 50 mm.
On the guides we attach the mechanism for the angle of rotation of the tabletop. We drill through holes with a diameter of 10 mm and fix the axles in them, relative to which the tabletop will rotate. On the reverse side, we drill through holes with a diameter of 20 mm, which serve to fix the tabletop at the desired angle with the help of bosses, in 5-degree increments.
We check the operation of the mechanism of the angle of rotation.
The surfaces of the assembled desk are sanded with a fine-grained sandpaper, moistened and stained with a stain.
As a lower fence, an aluminum strip with an arcuate edge is used, which is inserted into a groove selected by a circular saw with a slight indent from the front edge of the table top.
From below, a corrugated steel sheet is attached to the side walls of the desk, which acts as a support platform.
In conclusion, a footboard made of aluminum pipe is installed at the desired level.
Standing desk - drawings
Rice. A. To assemble such a desk, it is enough to connect the parts with glue and screws. The footboard can also be fixed with screws by screwing them from the side of the front edges of the side walls.
Rice. B. Adjacent edges of the tabletop and pencil shelves are adjusted to each other and connected on a rail.

The first table, as expected, has four support legs. But they are not connected to the table top as a common frame, but in pairs with each other. The legs are made from single boards 600x80x20 mm. From below, they are mounted on supporting crossbars made of the same boards 500 mm long with lugs-thrust bearings and reinforcing triangular struts on both sides of each leg - for greater stability. From above, each pair is connected by double horizontal ties, being between them; the entire assembly is fixed with two furniture screws with wing nuts. On the same screws, the countertop racks are attached, which are also included between the ties, close to the legs, which ensures the necessary rigidity and stability of the structure. Dimensions of boards-racks 650x80x20 mm. Eight screw holes are drilled in each stand to allow the table to be adjusted in height and tilt. At the top, the racks are connected by crossbars, on which a tabletop measuring 1200x800x20 mm is laid, having an anti-slip rail attached at one end, holding the shield on the crossbars in an inclined position. To do this, ledges under the rail were sawn in the crossbars.
The second table-desk differs primarily in a different solution of the supporting part: it has no legs, as such. Their role is played by two right-angled triangles.
1 - transverse support (4 pcs.), 2 - triangular strut (8 pcs.), 3 - leg (4 pcs.), 4 - double coupler (2 pcs.), 5 - countertop stand (4 pcs.), 6 - tabletop cross member (2 pcs.), 7 - anti-slip rail, 8 - tabletop.
1 - countertop, 2 - stiffening panel, 3 - footboard, 4 - countertop support cross member, 5 - external boards of the inclined parts of the supports, 6 - insert of the inclined parts of the supports, 7 - external strut boards, 8 - insert of the struts, 9 - boards external vertical parts of the supports, 10 - insertion of the vertical parts of the supports, 11 - boards of the external horizontal parts of the supports, 12 - insertion of the horizontal parts of the supports, 13 - holes for adjusting the inclination of the tabletop, 14 - pin strut clamps (dowels).

They can be made from wooden beam suitable section, but better - from a package of planks. This option has undeniable advantages. And not only in greater availability of material. The main thing is that, by manipulating three boards of different lengths, it is easy to obtain a hinged joint and the desired groove at the ends and even in the middle of the workpiece without any sawing or gouging. Due to this, a spike and an eye are formed at the junction of the horizontal and vertical parts of the support, and spikes at their ends - under the joint with the inclined part. The latter, in turn, has lugs at the ends and a slot-slot in the lower half in the same way. The same can be said about the strut: by pushing the middle plank relative to the outer ones, we get a spike on one side, and an eye hinge on the other. With its spike, the brace moves along the slot of the inclined part of the support and is fixed in one of its holes, setting the required slope of the tabletop.
the triangular supports are connected in two places: from the bottom - by a footboard, from the back - by a stiffening panel. Joints are provided with either plug-in round spikes (dowels), or metal corners, or wooden blocks.
The boards that make up the support and the strut are interconnected by any convenient way, starting from knocking down with nails and ending with gluing under pressure (carpenter's glue, casein, PVA). After manufacturing, they are sanded and polished (if it is supposed to be coated with furniture varnish) or putty, followed by painting. The same applies to countertops. If it is made of thick plywood, then it is quite possible to varnish it, since the wood has a beautiful pattern. And it is better to paint a type-setting from individual boards or from chipboard, after carefully sanding it with sandpaper, puttying it and sanding it again. It is advisable to apply the paint in several layers with intermediate drying during the periods indicated on the label of the can.
A good aesthetic effect can be achieved by using multi-colored enamels. So, if the tabletop and its supporting cross with a brace are painted in one color (for example, lilac), and the triangular supports, together with the stiffening panel and the bottom bar, in another, say, purple, then, in combination with the originality of the design, this will immediately turn homemade furniture to "branded".
Do-it-yourself growing school desk, drawings, diagrams and functional dimensions of the table that can ensure the normal and healthy development of the child during classes.
Requirements for children's tables are regulated by GOST 11015-93 "Student Tables". Based on the specified GOST, they are made in six numbers and have their own color marking, depending on the average height of the student.
The model described in this article allows you to adjust the desk in two functional sizes for the average height of a student from 105 to 180 (cm):
- along the height of the working plane from 460 to 760 (mm) (∆h = h1 – h = 300) with an interval of 50 (mm)
- by the angle of rotation of the working plane from 0 to 16° (∆φ = φ1 – φ = 16) (four positions 7, 10, 13.16°)
- Tabletop.
- Movable stands.
- Fixed racks.
The size of the working plane is 500x700x20 (mm). The desk cover (1) is installed horizontally, or fixed at an angle of 7, 10, 13 or 16°. Two plates are welded to the square pipe (2) 15x1.5 (mm): fastening of the rotary axis (3); fixing the angle of rotation of the table top (4). The tube (2) is attached to the tabletop with four screws (6). The end plane is closed with a decorative cap (5). The tabletop has two recesses 220x20x5 (mm) for pencils, pens and other accessories.
2. MOVABLE RACKS
The structure is welded from metal pipes: square (3) fifteenth; rectangular (6) size 35x15x2.5 (mm). To increase the rigidity of the structure, a plate (4) in the form of a right-angled triangle with sides 20 and 50 (mm) is welded to the corner joints. A wooden shelf (1) measuring 700 x 107 x 20 (mm) with a stop (2) is attached to the pipes. The end plane of the pipe is closed with a decorative cap (5).
3. FIXED RACKS
Welded from rectangular pipes (1) 40x2x2.5 (mm). By analogy with movable jays, a plate (3) is welded to the corner joints. The end face is closed with a decorative cap (3).
The figure shows the desks at minimum and maximum resizing.
