Abstract

FIELD: human vital needs satisfaction.

SUBSTANCE: folding table comprises a tabletop and racks which are connected to the tabletop through supports by means of pins, and oppositely arranged racks are rotatable on planes passing perpendicular to the tabletop plane and axes of the oppositely arranged racks which are connected to the bearing surface at the bottom part through cone regulators and interact with a fixing device moving along their axes. The rotation axes of the oppositely arranged racks form a predetermined angle with respect to the axis of the tabletop passing through the center of gravity.

EFFECT: increased rigidity of the structure.

Description

The invention relates to consumer goods, in particular to folding tables that can be used both in long hiking trips, geological and other expeditions, and in places of communication for a large number of people, for example restaurants, production halls, etc. In the manufacture of tables and other furniture, materials such as wood, plastics, metals, glass, or a combination of them, depending on the overall weight and characteristics and purpose of the product, can be used.

Known portable portable folding table (see. Russian patent No. 2564228), the disadvantage of which is its relative complexity of the design, the limitations of its use and the serial production of the use of non-standard technological equipment.

The closest analogue of the claimed invention is document KR 20020087167 A, cl. A47B 3/08, 11/22/2002 (D1), which reveals a folding table containing a countertop and racks. The racks through the stops by means of pins are connected to the countertop. Opposite racks have the ability to rotate on planes passing perpendicular to the plane of the countertop and the axes of the opposite racks. The disadvantage of the invention is that when you rotate the racks, they overlap each other, which leads to an increase in the dimensions of the device.

The technical result of the invention is to reduce the overall dimensions during transportation of the device and expand its functionality.

The specified result is achieved by the fact that when folding the racks they are located around the perimeter of the countertop. And the expansion of functionality is achieved by the fact that the racks interact with several planar latches that play the role of shelves.

In FIG. 1 shows a folding table device with a circular worktop in the working position. It contains a countertop 1 with stops 3 fixed to it, onto which racks 2 are attached using pins 4, which can rotate planarly relative to the pin axes. Racks 2 through cone-shaped regulators 6 interact with a supporting surface, for example a floor. The regulators with the help of a thread change the distance from the surface of the countertop to the supporting surface. The latch 6 moves along the racks along their entire height. The latches, like the table top, can have any given shape, for example, a wave-like, ring, circle, rectangular plate with rounded corners, etc. When performing countertops in a wavy shape, it is possible to insert pallets into the side cavities. The impact on the countertop and the table as a whole of radial loads does not violate the parallelism of the racks. Raising the latch to touch the tabletop, it becomes possible to rotate the racks by 90 degrees, ensuring the position of the table in a folding condition.

In FIG. 2 shows a table in a folding condition. To ensure the fixation of the uprights, arcuate tape springs are attached to the lower surface of the latch 7. In order to ensure uniform table resistance to lateral loads, the axis of rotation of the opposite struts form a predetermined angle relative to the axis of the countertop passing through the center of gravity.

In FIG. Figure 3 shows a stepped rack, on the steps of which are latches that play the role of shelves. When making latches with rectangular cutouts, it is possible to insert loading boxes there.

From the foregoing, it follows that the method of manufacturing furniture, which consists in the fact that the step racks, each step in the cross section of which may have a circle, or a rectangle, or a combination thereof, are strung with plane clamps, after which walls, doors, and others can be fixed to the resulting structure furniture attributes.

The claimed invention can find the widest application in the production of furniture and other household goods, for example, in the manufacture of tables for various purposes, chairs, armchairs, various wall shelves, shelving, walls, etc. When installing large-sized furniture, its simple, fast and high-quality assembly and installation is ensured. During transportation, loadability is significantly increased, which leads to a reduction in the cost of goods.

Claims (5)

1. A folding table comprising a countertop, racks that are connected through stops with pins to the countertop, and opposed racks can rotate along planes perpendicular to the plane of the countertop and the axes of the opposite racks, which are connected to the supporting surface in the lower part through conical adjusters and interact with a latch moving along their axes, characterized in that the axis of rotation of the opposite struts form a predetermined angle relative to the axes and passing through the center of gravity of the countertop. 2. A folding table according to claim 1, characterized in that the latch has any predetermined shape, moreover, when several latches are positioned, the racks have a stepped shape with the number of steps on the rack equal to the number of latches. 3. A folding table according to claim 1, characterized in that the countertop has a wavy shape. 4. The countertop according to claim 3, characterized in that pallets are installed in the hollows of the undulating countertop. 5. A folding table according to claim 1, characterized in that the racks contain rectangular cutouts into which drawers are inserted.
