Description

Field of technology

The utility model relates to light industry, namely to elements of furniture for lying and sitting, located on beds, sofas, armchairs, and can be used when arranging a sleeping place or resting place as a mattress and/or pillow or an accessory for sleeping and relaxing . State of the art

The invention is known RU 2228162 C2 “Mattress for an immobilized patient”, IPC A61G 7/057, containing an upper solid, lower joined panels and vertical walls made of breathable fabric. The internal volume of the mattress is divided into isolated cells, the vertical (side) walls of which are attached to the upper and lower panels and along the corner edges of the cells - to each other. The cells are filled with a filler, which is a bulk biologically neutral material with low thermal conductivity, consisting of smooth round particles, and/or plant seeds with medicinal properties, such as flax, and/or millet, and/or oats.

The disadvantage of the above-described technical solution is the high complexity of maintenance due to the large amount of filler in the mattress, which must be removed during the physical and chemical process of cleaning the mattress, the lack of uniform distribution of pressure of the mattress on the body when it changes position due to the same rigidity of the filler in all cells of the mattress. (RU 2228162 C2, http://new.fips.ru).

There is a known utility model RU 111740 U1 “Springless mattress”, MPK A47C 27/00, containing a base, the design of which consists of a combination of at least three layers of elastic material, in which the outer layers have one profiled horizontal surface, with which they come into contact with the corresponding the surface of the inner layer, which provides a network of multiple horizontal through breathable channels between the layers of such a three-layer combination. This design allows air access to all layers of the mattress base, which helps improve the ventilation of the proposed springless mattress. Additional vertical through holes in each of the three layers of such a three-layer combination provide a network of vertical air-permeable channels, which, intersecting with a network of horizontal channels, further improve the ventilation of the proposed springless mattress. In a springless mattress, the rigidity of the inner layer of any three-layer combination is higher than the rigidity of any of the outer layers of this combination in contact with it. The outer layers of any three-layer combination can be made of a material of different or the same stiffness. The inner layer of any three-layer combination is connected to the outer layers of this combination by means of an adhesive connection. If there is more than one three-layer combination in a mattress, adjacent combinations are connected to each other by means of an adhesive connection. The layers of the mattress can be made of latex, or foam rubber, or elastic polyurethane.

The disadvantage of the above-described technical solution is the lack of uniform distribution of pressure of the mattress on the body when it changes position due to the same rigidity of the outer layer of the mattress over its entire area. (RU 111740 U1. http://new.fips.ru).

Of the known solutions, the closest in technical essence to the claimed object is the utility model RU 123307 U1 “Springless mattress”, MPK A47S 27/00, containing two flat bases made of polyurethane foam or other elastic material in the shape of a parallelepiped with front and back surfaces, glued together between their back surfaces. Open surface channels run along the back surfaces of each base in two mutually perpendicular directions, forming, after gluing, a network of mutually intersecting mattress ventilation channels with a constant pitch along the short side of the mattress. Open surface channels run along the front surfaces in two mutually perpendicular directions with a constant pitch along the short side of the mattress and a variable pitch along the long side of the mattress. At the intersection of the surface channels on the front surfaces (sides) of the mattress bases, through holes are made, located perpendicular to the plane of the surface channels and forming a network of freely communicating channels with them. On the back side of the mattress base there are also open surface channels running both along and across the surface of such a base, located preferably at an equal distance from the horizontal surfaces of such a base and forming a network of freely communicating channels with other holes and surface channels. Surface open channels on the front surface of each base form elements of different shapes and areas on the front surface of these bases. Manufacturing the bases of the proposed mattress with surface channels of different given diameters with a given pitch on the front side of these bases and through holes of a given diameter located with a certain given pitch perpendicular to the surface channels makes it possible to create a mattress with seven zones located sequentially one after another with different rigidities along the long side mattress.

The disadvantage of the above-described technical solution is the lack of uniform distribution of pressure of the mattress on the body when it changes position due to the presence of fixed zones of rigidity in this mattress. (RU 123307 U1, http://new.fips.ru).

The technical challenge for solving the above-described disadvantages is to develop a piece of furniture with low maintenance complexity, which has rapid adaptation to changes in body position with a uniform distribution of pressure on its surface.

Essence of a utility model

The stated technical problem is solved due to the fact that the furniture element is made in the form of a monolithic elastic block (1) FIG. 1 the front and back surfaces of which are formed by cells (2), each of which contains adjacent walls (3), having a change in cross-sectional area in height from the front surface to the back surface of the furniture element, while the walls (3) of the cells (2) have different height and width to create different structural rigidities of the furniture element, as well as to ensure uniform pressure distribution due to giving the front surface of the furniture element the anatomical shape of the body or its part.

The furniture element is made in the form of a monolithic elastic block (1) Fig. 1 containing front, back and side surfaces. This design has low maintenance complexity due to the fact that this design of the furniture element is easily subjected to the physical and chemical cleaning process at low water temperatures. The front and back surfaces of the block (1) of the furniture element are formed by cells (2), each of which contains adjacent walls (3) having a change in cross-sectional area in height from the front surface to the back surface of the furniture element. This design allows the furniture element to quickly adapt to changes in body position and evenly distribute pressure on its surface by changing the position and geometry of the walls (3) of the cells (2), as a result the shape of the cells (2) changes, and the changing cross-sectional area of the cells (2) in height from the front surface to the back surface makes it possible to ensure the rigidity of the cells (2), allowing them to withstand high loads without compromising their integrity. Cells (2) Fig. 1 the front and back surfaces of the block (1) of the furniture element form vertical through air channels that remove heat from the body, maintaining a comfortable temperature.

In the particular case of the execution of cell (2) of FIG. 1, the front and back surfaces of the block (1) of the furniture element form blind vertical holes.

In a particular case of execution, the front and back surfaces of the block (1) of FIG. 1 piece of furniture contains several layers of cells (2), while the cells (2) of one layer have a larger or smaller cross-sectional area relative to another layer, and the layers of cells (2) form vertical through air channels.

In the particular case of the cell layers (2) of FIG. 1 form blind vertical holes.

Cells (2) Fig. 1 the front and back surfaces of the block (1) of the furniture element have a different shape, namely, round or square or triangular. The walls (3) of the cells (2) have different heights and widths to create different structural rigidities of the furniture element, as well as to ensure uniform pressure distribution due to giving the front surface of the furniture element the anatomical shape of the body or part of it by changing the shape of the cells (2).

Cells (2) Fig. 1 the front and back surfaces of the block (1) of the furniture element have a triangular or square or rectangular or trapezoidal or semicircular or hexagonal cross-sectional shape.

In a particular embodiment, the furniture element has a cavity for replaceable filling located between the cells (2) of Fig. 1 front and back surfaces of the block (1).

In a particular case of execution, the furniture element contains an additional replaceable layer to increase the height of the furniture element, which has the ability to interface with the front surface of the block (1) of the furniture element.

In a particular case of execution, the furniture element consists of several monolithic elastic blocks (1) FIG. 2 interconnected.

In a particular case of execution, monolithic elastic blocks (1) FIG. 3 furniture elements are interconnected with each other and with a layer of solid damping material (4) located on the back and/or front surfaces of the blocks (1), covering the blocks (1) over the entire area. This design increases the elasticity of the furniture element and the rigidity of its structure.

The piece of furniture has a square or rectangular or trapezoidal or semicircular or round or oval shape.

A piece of furniture has different dimensions depending on the size of the piece of furniture or on the functional purpose, namely use, for example, as a mattress or pillow.

In a particular case, a furniture element is used as an additional material in the design of a piece of furniture, namely, the furniture element is mated with fabric or polyurethane foam or latex or coconut coir or a spring block or placed in a case and used as a structural element of furniture and goods for sleep and relaxation.

The technical result of the claimed solution is to create a piece of furniture with low maintenance complexity, which has rapid adaptation to changes in body position with a uniform distribution of pressure on its surface.
