Description

ELASTIC TRANSFORMABLE BLOCK FROM DEFORMABLE MATERIAL

The utility model relates to light industry, namely, to furniture production and can be used for the manufacture of seats for household and office furniture, mattresses, etc.

A foam insert for a mattress is known from the patent literature. which on its surface has a large number of cells, each of which consists of cylindrical short channels of various diameters, which provide variable stiffness of the mattress (see the application of France. CU 2729063, class A 47 A 27/14 from 1996).

Closest to the proposed problem is a mattress (see US patent No. 6026527, class A 47 C 27/00 from 2000), which has a rectangular cross section and is equipped with a thickness of several uniformly spaced weakening section elements that make it possible to bend it when application of effort.

The objective of the proposed utility model is to expand the technological capabilities of an elastic transformable block from a deformable material used for the production of mattresses.

The task is achieved due to the fact that the bend line of the block is formed by hollow cells having different configurations and profiles, which are made on both sides of the block thickness, and the angle of the longitudinal axis of the cell to the horizontal plane of the block lies in the range from O to 90 °. The configuration of the cells has the form of geometric shapes, for example, an oval, rectangle, etc., which are made on the surface of the block by its

thickness and form a fold line. The shape of the cell profile in the cross section of the block has a constant or variable cross section along its entire length, can have the configuration of a stepped figure, can be made in the form of a through channel of the cross section of the block or in the form of a blind hole. In this case, the fold line of the block can be formed by one or several rows of hollow cells.

The drawings show a schematic diagram of a utility model of an elastic transformable block from a deformable material for the production of mattresses:

in FIG. 1 shows a block with cells in expanded form;

in FIG. 2 - in a form bent along the fold line;

in FIG. 3 - presents various types of cell configurations and the scheme of their deposition for the formation of the fold line;

in FIG. 4 - presents options for the cross section of the profile of the cells on one of the horizontal surfaces of the mattress;

in FIG. 5 - shows an embodiment of hollow cells on both horizontal surfaces of the mattress.

The elastic transformable block 1 of the deformable material is a liner for the mattress and has a rectangular shape. It is equipped with weakening its cross section cell elements 2, which are spaced along its thickness and have a different profile and depth along the thickness of block 1. Hollow cells 2, deposited along the horizontal plane of block 1, form a fold line 3 of block 1, they are performed on both sides of the intended fold lines 3 and are applied in the specified order, depending on the type of furniture production, the rigidity of the block material, etc. (see. Fig. 1). The configuration of the hollow cell 2 is determined

the need to have a clear fold line 3, which is closer to a straight or wavy (see Fig. 3). The shape of the hollow cell 2 and its depth also vary and depend, for example, on the elasticity of the material, the shape of the furniture or the number of rows of cells forming the fold line 3. The profile profile of the cell 2 in the cross section of block 1 may have a constant cross section over its entire thickness or have a step configuration (see Fig. 4). Cells 2 can be made in the form of a through channel 4 or blind hole 5, and cells 2 can be applied both on one of the flat sides of block 1 and on both sides (see Fig. 5) and can be located in one , and in several rows (see Fig. 3).

The material for an elastic transformable block can be, for example, polyurethane foam - a deformable material used for the manufacture of furniture, seats or mattresses.

The geometry of the application of hollow cells 2 is determined by the requirements for the fold line 3 (Fig. 3) and the complexity of their manufacture depending on the type of production (single, mass, etc.). Cells 2 can be made in the form of through channels 4 or blind holes 5, which, when an external load F is applied and the unit is bent, provide for “flowing in of wrinkled areas. The angle of the longitudinal axis of the cell to the horizontal plane of the block can lie in the range from 0 to 90 °. This makes it possible to vary the position of the part of the block 1 (Fig. 2) at an angle f relative to the fold line along the thickness of the block 1.

The utility model is industrially applicable, extends the operational capabilities in the manufacture of furniture of various shapes and designs. allows you to abandon the spring structures and furniture stuffing, apply

modern elastic materials, which are more widely used every year.
