Description

TRANSFORMABLE EDUCATION TABLE

The utility model relates to furniture for educational institutions and can be used as both educational and laboratory equipment.

A training table is known, comprising a tabletop mounted on the base with a stand for placing educational accessories, which includes horizontal guides mounted on the tabletop, a vertical supporting element mounted on horizontal guides with the possibility of reciprocating movement to reduce eyestrain, and means for moving the vertical supporting element, see RU 2022512, M. cl. A47B 41/00, 1993.

The disadvantage of this technical solution is the inability to increase the area of the working surface of the countertop.

A convertible training table is known, comprising a base, a tabletop and a stand for reading and writing box-shaped with a hinged lid and a rear wall located on the tabletop, the hinged lid having an inclined working surface, the stand is equipped with a triangular-shaped stop element placed in the inner cavity of the stand with adjoining its rear wall, the tabletop is formed by the bottom of the stand and is connected to its rear wall by means of loop nodes with the possibility of rotation and stirring; Tola perpendicular to the countertop, in the same plane with the hinged lid, while the thrust element is installed adjacent to the back wall of the stand to increase the surface of the table, while turning the hinged lid and the back wall together; the stand is provided with side walls connected to the countertop by means of brackets, while the loop nodes connecting the back wall of the stand with the countertop are made detachable, see RU 2014794, M. cl. A47B 83/02

This device is adopted as a prototype of this utility model.

The back wall of the stand can be rotated together with a hinged lid and placed in the same plane from the back of the table

perpendicular to the countertop, the width of the countertop increases slightly (by the width of the supporting element).

The disadvantage of this technical solution is that in the working position the hinged lid can be used only for reading or writing; it is impossible to put any objects on it, such as laboratory equipment; in order to put any objects on the table, except for notebooks or books, it is necessary to turn the hinged lid; if it becomes necessary to bring the table into working position, laboratory equipment will have to be removed to make room for the hinged lid, which causes serious inconvenience; in addition, the device is unnecessarily material-intensive, since the hinged lid, in fact, duplicates the countertop.

The basis of this utility model is the solution to the problem of creating a training table, which can be easily converted into a laboratory table and vice versa, while in the case of a reverse transformation, laboratory equipment can remain in place; the material consumption of the table should be reduced.

According to a utility model, this problem is solved due to the fact that in a convertible training table containing a base and a tabletop horizontally mounted on it, the tabletop is made of two parts - fixed, facing the person sitting at the table, and movable, which

located on the back of the table, mounted on at least two vertical brackets, made with the possibility of vertical rotation relative to the base and fixing in the upper position, while the fence is attached to the movable part of the tabletop perpendicular to it from below, and an additional attached to the bottom of the fence a shelf, the upper surface of which is parallel to the upper surface of the countertop, with the additional shelf located under the movable part of the countertop.

The applicant has not identified technical solutions that are identical to the claimed utility model, which allows us to conclude that it meets the criterion of "novelty.

figure 1 is a training table in a position intended primarily for reading and writing, in a perspective view;

figure 2 is a training table in the position intended for laboratory work, in a perspective view;

in Fig.3 is a section I-I in Fig.1;

The converted training table contains a base, including vertical racks 1 interconnected by horizontal elements, a fixed part 2 of the tabletop, a movable part 3 of the tabletop, which is mounted on brackets 4 and 5; a guard 6 is attached to the movable part 3 of the tabletop from below and perpendicular to it, to the lower part of which an additional shelf 7 is attached, the upper surface of which is parallel to the upper surface of the countertop, with the shelf 7 located under the movable part 3 of the countertop; brackets 4 and 5 have the ability to move vertically relative to the base and fixation in the upper position; in a specific design, this is achieved by the following means. In the brackets 4 and 5, vertical grooves 8 are made; in the racks 1 of the base, located on the back of the table, vertical grooves 9 are made, paired with holes 10 in the upper part, while the diameter of the holes 10 exceeds the width of the grooves 9.

In the brackets 4 and 5, spring-loaded cylindrical clamps 11 are made in a stepped form, with a step of a smaller diameter of the clamp 11 facing the rack 1 and placed in the groove 9, and the other

the step has a larger diameter corresponding to the diameter of the hole 10. In the uprights 1, the fingers 12 are rigidly fixed to the thread, entering their free ends into the grooves 8 in the brackets 4 and 5. In the brackets 4 and 5 above the fingers 12, spring-loaded clamps 13 are fixed; between the base and the movable part 3 of the tabletop there is a rubber shock absorber 14. In the position of FIG. 1, the movable part 3 of the worktop lies on the shock absorbers 14. To convert the device into a laboratory table, the movable part 3 of the worktop is lifted, while the brackets 4 and 5 move vertically upward relative to the uprights 1 grounds. The step of the smaller diameter of the latch 11 slides into the groove 9, and the finger 12 slides into the groove 8; under the action of the spring, the latch 13 extends. When lifting part 3 of the countertop to its highest position, the step of the retainer 11 with a large diameter enters the hole 10 of the rack 1 and fixes the movable part 3 of the countertop in this position. When lowering part 3 of the tabletop through the hole 15 in the racks 1, press with a thin rod, for example, with a pencil, onto the spring-loaded clamps 11, the step of the clamp with a large diameter comes out of the hole 10, part 3 of the countertop is lowered; while the step of the latch with a smaller diameter slides moving vertically down into the groove 9, and the finger 12 slides into the groove 8; finger 12 serves to prevent skewing when lowering

part 3 of the tabletop, which is lowered until the latch 13 falls onto the shock absorber 14. The latch 13 provides a gap between the part 3 of the tabletop and the base stand 1, which is necessary to prevent accidental pinching of the fingers when lowering the part 3 of the tabletop. Then press with some rod on the latch 13, which comes off the shock absorber 14, part 3 of the countertop is lowered and lies on the shock absorber 14, while the latch 13 slides on the surface of the rack 1; the device returns to its original position.

The converted training table is manufactured in the factory using conventional equipment and well-known materials, which determines, according to the applicant, his compliance with the criterion of “industrial applicability.
