Description

The utility model relates to the furniture industry and can be used in the design of a guide for a mechanism for moving hinged folding inserts of a sliding table.

From the prior art, see, for example, the description of the patent US4553485A, IPC A47B 1/03, publ. 11/19/1985, sliding tables are known, including a frame, first and second movable upper parts of the tabletop, as well as two hinged folding inserts equipped with a moving mechanism with two guides.

From the description of the patent CN212437736U, IPC A47B 13/08; A47B 3/00, pub.

Making the guides for the sliding table from metal has the following disadvantages:

high labor intensity of manufacturing;

insufficient precision in the manufacture of mechanism parts;

increased range of components due to the need to use two mirror-made metal guides;

increased complexity of installation of guides;

increased noise when changing table geometry;

increased effort when laying out the table;

deterioration in the appearance of the guides during operation (rust on working surfaces).

The design of the table guide, known from the description of the patent RU220167U1, IPC A47B 1/10, publ., is taken as the closest analogue of the claimed utility model. 08/30/2023

The guide includes a base made of polymer material, in which a longitudinal groove and through mounting holes are formed.

Making the guide from a polymer material has the following advantages:

low manufacturing complexity;

high manufacturing precision;

low noise when changing table geometry;

low effort when laying out the table;

unchanged appearance of the guides during operation.

The task that the utility model is aimed at achieving is to develop an innovative design of a guide made of polymer material to replace the metal guide used in the mechanism for rotating the K-0401 table leaves produced by DEGON-SERVICE LLC, and known, for example, from information sources:

http://www.tex.domfort.org/upload/degon-stol.pdf or

https://www.degon.ru/catalog/komplektuyushchie-dlya-stolov/mekhanizmy-povorota-vstavki-stola/k-0401-mekhanizm-povorota-vstavki-stola/ or http://furnitura-dv.ru/mehanizm -povorota-vstavki-stola-k-0401.

The technical result that the utility model is aimed at achieving is to reduce the labor intensity of assembling the sliding table.

The above technical result is achieved in a guide that includes a base made of a polymer material in which a longitudinal groove and through mounting holes are formed.

This technical result is achieved in that the base has two holes for inserting the lever axis, and the guide is equipped with a shelf connected to the base by ribs.

The utility model is illustrated by the following images.

In fig. 1 shows a guide for an extendable table.

In fig. Figure 2 shows a guide installed on the table frame, assembled with an axis and a lever.

In fig. Figure 3 shows part of an extendable table.

The positions in FIG. 1-3 are marked:

1 - guide; 2 - base; 3 - longitudinal groove;

4, 5 - through mounting holes; 6 - shelf;

7, 8, 9 - ribs connecting the base of the guide to the shelf;

10, 11 - holes for inserting lever axes;

12 - upper edge of the crossbar of the table frame;

13 - table frame crossbar; 14 - axis; 15 - lever; 16 - lever support;

17 - table section; 18, 19 - hinged folding inserts;

20 - table frame; 21 - finger with support.

The utility model can be successfully implemented in a guide 1, including (Fig. 1) a base in which a longitudinal groove 3 and through mounting holes 4, 5 are formed.

To implement the utility model, the following design changes are made.

In the base 2 there are two holes 10, 11 for introducing the axis of the left or right lever, respectively.

This allows the same guides to be used to attach to any of the table frame rails, regardless of whether the rail is located to the right or left of the folding inserts.

The unification of the guide design reduces the labor intensity of assembling the sliding table, since the installer does not waste time searching for the left/right guides.

The guide 1 is equipped with a shelf 6, which is connected to the base by 2 ribs 7, 8, 9.

The ribs 7, 8, 9 provide a connection between the base 2 of the guide 1 and the shelf 6 with minimal consumption of polymer material.

When installing the guide (Fig. 2), the shelf 6 is installed on the upper edge 12 of the crossbar 13 of the table frame and serves to ensure accurate installation of the guide 1 relative to the upper edge of the crossbar 13 of the table frame.

The presence of shelf 6 makes it possible to reduce the labor intensity of assembling the sliding table, since the guide is installed in the desired position without wasting extra time on ensuring the orientation of the guide.

Through mounting holes 4, 5 are made inside the longitudinal groove 3. This allows the design of the guide 1 to be the most compact.

The guide is made by casting from a polymer material.

ABS plastic (acrylonitrile butadiene styrene) can be used as a polymer material for the manufacture of the guide.

It is possible to use other polymer materials, for example, polyamide, polyvinyl chloride, etc.

The guide is used as follows.

Sections of the sliding table are moved in opposite directions, providing access to the table frame.

The first guide is placed on the upper edge of the first crossbar of the table frame and attached to the crossbar with threaded rod elements.

Similarly, the second guide is placed on the upper edge of the second crossbar of the table frame and attached to the crossbar with threaded rod elements.

The upper of the hinged folding inserts is equipped with levers, attaching the lever supports to the insert with rod threaded elements.

The upper of the hinged folding inserts is equipped with pins 21, attaching the pin supports to the insert with rod threaded elements.

The axles 14 of the levers 15 are inserted into the corresponding holes 10, 11 in the guides.

The fingers 21 are installed in the grooves of the guides.

When moving the upper folding insert from the lower position (Fig. 3), the second folding insert simultaneously moves.

As a result of the inserts moving along complex trajectories, they occupy an upper position flush with the table sections.

The table sections are shifted, connecting with the outer surfaces of the inserts.

Conducted patent research confirms the world novelty of the utility model.

The operation of prototypes of the utility model confirmed its industrial applicability and compliance with the stated technical results.
