Description

The invention relates to the construction of furniture, in particular to school desks, to equipment for workplaces, offices, and can also be used to equip dining rooms, cafes, restaurants, places for recreation. The proposed folding furniture will find application in computer centers, in a typewriting bureau, in the field of healthcare, as well as in other sectors of the national economy.

The aim of the invention is to increase the degree of unification of structural parts, the possibility of using these parts for various types and configurations of collapsible furniture, as well as improving convenience by improving the operational characteristics of the product.

Figure 1 shows a U-shaped tubular profile with a bent end; figure 2 - assembly options for two U-shaped tubular profiles: figure 3-6 - assembly options for four U-shaped tubular profiles, as well as the use in the design of additional elements from the pipes; Fig.7 is an embodiment of the school

desks with an armrest; Fig. 8 is a variant of a school desk with the ability to adjust the position along the height of the table and chair; Fig. 9 shows a method for attaching flat structural elements to a frame; in FIG. 10 is an embodiment of connecting tubular profiles to each other; Fig. 11 is a table top of a school desk for drawing and drawing. Figure 1 shows a U-shaped tubular profile with a bent end, as well as its mirror image. These tubular profiles are the main parts of the collapsible furniture offered. Using these parts, you can assemble various designs of collapsible furniture, which are shown in Fig.3-8. Fig. 3.4 shows various versions of the supporting structures for tables obtained by combining from U-shaped tubular elements, the free ends of which are closed in this case. Figure 5, Fig. B shows the supporting structures having two free (open) ends of the U-shaped tubular profiles, and also shows the use of additional parts from

pipes. Fig. 7 shows an embodiment of the use of U-shaped profiles in a school desk device, which are the supporting surfaces of a table and chair. The abutment surface for the back and elbow is formed by an additional spatial piece of pipe.

Tubular profiles, depending on the type and purpose of collapsible furniture, as well as the wishes of the customer, can be interconnected in various ways. This can be a connection using various fasteners (bolts, pins, connecting rods, etc.), as well as a tight fit on a cone formed by deformation of the end of the tubular profile. The table top, seat and backrest can also be secured with various fasteners. Clamps covering the pipe and attached to the surface of a countertop or other element of collapsible furniture can be used as such fasteners.

In the school desk, which can be used for drawing and drawing, the countertop consists of two parts, hinged together. one of which is fixed motionless on the frame and plays the role of a working surface for placing the tool next to a seated one, while the other has the ability to deviate vertically and serves as a working surface for drawing and drawing.

The connection of the tubular profiles with each other can be made with the possibility of moving (translationally or rotationally) relative to each other in space. Thus, collapsible furniture can be rebuilt to other sizes or assembled into a more compact form.

An example of such a solution is the school desk shown in Fig. 8. The table, seat and back of such a desk can be height-adjustable, which makes it possible to use it for people with various anthropometric data. The table consists of a frame made of two U-shaped profiles 1. worktops 2. rod 3. with which the height of the worktop is adjusted. The chair also includes U-shaped profiles 4, seat 5, back 6. rods 7 and 8, as well as support for the back and elbow 9. Using the rod 7, the height of the seat is adjusted, and with the help of the rod 8, the position of the back . The tabletop 2, seat 5, backrest 6 are fastened to the frame with the help of clamps 10 and

fasteners 11 (see Fig.9). The connection of the tubular U-shaped profiles with each other, as well as with the rods 7 and 8, is carried out using fasteners 12 and 13 (see Fig. 10).

In FIG. 11 shows the top of the school desk for drawing and drawing, consisting of two surfaces 14 and 15, interconnected pivotally and two braces 16, mounted on the surface 14. The adjustment of the position in the space of the surface 14 is carried out using bushings 17, mounted on the surface 15 rotatable, and clamping screws 18. When the working surface 14 is horizontal, the braces 16 are located along the side faces of the countertop.

When adjusting the position of the table top 2. the seat 5 and the backrest 6 in height must be unscrewed fasteners 12 and 13. move the upper U-shaped profiles 1 and 4, as well as the upper part of the support for the back and elbow 9 to the desired level until the holes coincide in the rods x 3.7 and 8, and then fix the desired position with the fasteners 12 and 13.

When adjusting the position of the working surface for drawing and drawing 14, it is necessary to loosen the screws 18, move the surface 14. to the desired angle. The braces 16 will then move in the bushings 17, which, in turn, will rotate by the required angle. Then, it is necessary to fix this angle of installation of the surface 14 with clamping screws 18.

The proposed collapsible furniture has a number of advantages over the prototype. The use of the unified U-shaped profiles described above in the design greatly simplifies it, and also contributes to the modification of this collapsible furniture. In fact, from the same U-shaped profiles, at the request of the buyer, furniture with a wide range of consumer properties can be assembled in various shapes and purposes. The claimed design is expedient and rational, convenient in operation, and can be carried out under conditions of industrial production using standard equipment, modern materials and technology.
