Description

1. Name of utility model:

folding table

2. The technical field to which the utility model relates.

The utility model relates to folding furniture, which can be used in everyday life, on vacation, in industrial and office premises.

3. The prior art.

Among folding tables with different designs, a close analogue of the utility model is a folding table consisting of a supporting frame 1 (Fig. 1), the top of which is the middle table top 8 (Fig. 3), two side folding tabletops 2 (Fig. 1), which are held when the table is opened by the supporting frames 3 (Fig. 1). Lateral folding tabletops and supporting frames to the support frame are fastened with piano hinges. When the table is closed, the supporting frames are retracted inside the support frame. This table design provides good compactness, due to which the table has gained popularity among consumers. The folding tables available in retail are made of particle boards (chipboard), which have a significant specific weight, so the weight of these tables is 30-50 kg, which reduces their mobility. Not every person, especially women and children, if necessary, can carry such weight. The methods used to connect table elements made of chipboard with fasteners, usually metal ones, do not provide long-term rigidity of the table structure and require fastening over time, since the safety requirements for further operation of the table are not guaranteed.

4. Disclosure of a utility model.

When creating a utility model, the problem was solved to achieve the following technical result: while maintaining such useful quality of a folding table-analogue as compactness, increase the mobility of the table by reducing its weight, increase and make long-term stiffness of the supporting frame and the table as a whole.

Figure 1 schematically shows a folding table in the working position;

figure 2 section aa in figure 1; figure 3 supporting frame with an average countertop,

axonometry. In figure 1, 2, 3, the following numbering of parts and components referred to in the following description of the utility model is applied:

1- supporting frame with an average countertop;

2- side folding tabletop;

3- supporting frame;

4- spacer;

5- upper cross member of the side frame of the support frame;

6 - cross-section of the middle countertop frame;

7- plywood canvas of the middle countertop;

8- middle countertop;

9- side frame of the support frame;

10- connecting strip.

The technical solution for reducing the weight of the table is that instead of the massive middle and side countertops and sides of the supporting frame made for an analog table made of chipboard, the utility model uses frame-type worktops made of thin-sheet plywood blanks that are mounted in frames made of lightweight wooden blocks and side frames of the bars.

The technical solution to ensure the reliability of the connection of the table elements is that instead of the standard fasteners, new structural elements are used - two wooden spacers 4 (Figs. 2, 3) that can be made of another material, provided that its strength characteristics are not lower tree. Spacers 4 are attached at one end to the cross members of the middle table top frame 6 (FIG. 2), at the other end to the upper cross members of the side support frames 5 (FIG. 2). After the connection in the lower part of the side frames of the support frame by the connecting bar 10 (Fig. 3), a closed rigid table support frame is obtained.

Over 10 years of operation of the prototype of the utility model, weakening of the fastenings of the table elements and, accordingly, the violation of the rigidity of the supporting frame was not found.

5. Implementation of a utility model.

The implementation of the utility model begins with the manufacture of table elements with the subsequent assembly of these elements in accordance with the developed technical documentation. As blanks for the manufacture of table elements, wooden bars of various rectangular sections and rectangular blanks from thin-sheet plywood are used. In the manufacture of the table, the sequence of production of table elements is not regulated. The following elements are subject to manufacture: the middle countertop 8 (Fig. 3), two side hinged countertops 2 (Fig. 1), two lateral supporting frames 9 (Fig. 3), two supporting frames 3 (Fig. 1), a connecting lower strip

10 (figure 3) and two spacers 4 (figure 2, 3). Manufactured parts are assembled into table elements using PVA glue. After the support frame is assembled, the following are used for this: the middle countertop, two side support frames, a connecting lower bar and two spacers. Initially, the spacers at one end are attached to the cross-members of the middle table top frame 6 (Fig. 2), then the cross-members 5 (Figs. 2, 3) of the side support frames are attached to the middle countertop with the spacers, after which the lower parts of the side frames are fixed with a connecting strip, all connections are made using PVA glue. As a result, a closed contour of the table supporting frame is formed. The final assembly of the table is carried out by connecting the supporting frames and the side folding table tops with the supporting frame using piano hinges. The advantages of the utility model become apparent when operating the table. Reducing the weight of the table allows you to move the table indoors without the need for great efforts, the cross-members of the side frames 5 (Fig. 3) make it convenient to hold the table by weight with your hands. The increased rigidity of the support frame makes it possible to use the table for repair work in the premises when a reliable, stable stand is required.
