Description

Technical field

The claimed utility model relates to pieces of furniture and bedding and can be used for the manufacture of mattresses.

State of the art

A foam mattress is known from the prior art (CA patent 2533009 dated February 10, 2005), made from a block of elastic polyurethane foam with a density of 40 kg / m ³ or any other density, while this block is first cut on a programmable machine along the main side, and then turned on 90° is a degree angle to its smaller side. This produces a certain number of springs, depending on each type of mattress. The number of coils of each spring depends on the position of each spring in the mattress in order to change its flexibility so that the mattress can perfectly adapt to the contours of each user or so that the flexibility remains constant throughout the mattress. Numerous variations can be realized with the same height of the entire mattress (fewer spirals with the same thickness of the spiral and more base and uncut, etc.; the width of the spiral can be changed, as well as the number of spirals, the size of the spiral), the inclination of the spiral axis, the total height of the area - bulges or depressions - etc.). The upper surface of the product is covered with a viscoelastic layer of polyurethane with a density of 50 kg/m ³ , 4 cm thick and a threaded gasket.

A mattress with two springs is known (see patent KR 1020030044880 dated 06/09/2003), consisting of latex foam inside the cover, several high-density polyurethane foams with holes for air circulation inside the latex foam, and metal helical springs, consisting of independent double springs inside the polyurethane foam .

The disadvantages of the known designs is insufficient anatomy.

The closest in technical essence to the claimed device is a mattress with soft and hard areas (see patent CN 212815470 dated March 30, 2021), containing a rectangular frame and a shock-absorbing layer covering a rectangular frame, a hard zone and a soft zone are located on both sides of the central axis of the cushion layer in the length direction of the cushion layer, respectively, the cushion layer is made of polyurethane sponge materials, wherein the density of the hard region of the cushion layer is greater than the density of the soft region; a plurality of springs are evenly distributed in a rectangular frame, two ends of each spring abut against two opposite inner side walls of the shock-absorbing layer, respectively, while the stiffness coefficient of the springs corresponding to the hard areas is greater than the stiffness coefficient of the springs corresponding to the soft areas.

The disadvantage of this design is its complexity due to the use of springs with different stiffness coefficients and polyurethane foam with different densities.

Utility Model Disclosure

The objective of the proposed utility model is to create a mattress with zonal load distribution.

To achieve this task, it is proposed to create a mattress with zonal load distribution, containing bulk fillers placed in a fabric cover, a block of independent springs and a polyurethane foam layer with a density of 40-55 kg/m ³ located around it, characterized in that the polyurethane foam layer is cut in a longitudinal horizontal plane along a sinusoid so that the shoulder area and the pelvic area are more elastic. To do this, the polyurethane foam layer is cut along a sinusoid with a wave height of 6-7 cm from the base of the polyurethane foam, while the wave height in the middle (along the length) of the polyurethane foam is 5-6 cm, and at a distance of 50 cm from the middle to the left is 7-8 cm. This zone, where the wave heights are 6-5 and 7-8 cm, corresponds to the location of the shoulder and pelvic zones.

As a block of independent springs, springs 5-7 cm high with an inflection angle of up to 180° are used.

As a bulk filler, foam rubber, batting, strutfiber, Hollcon, latex, synthetic winterizer are used.

To protect the layers of polyurethane foam from springs, a non-woven needle-punched fiber of 500 g/m ² is glued to the cut.

The principle of this mattress lies in the hybrid use of the resistance of the spring block to polyurethane foam with special contour cutting for zonal load distribution. At the same time, the contour cutting is made so that the shoulder area and the pelvic area are more elastic, thanks to which the person assumes a physiologically correct position.

The technical result provided by the given combination of features is an increase in the anatomy of the mattress.

Implementation of the utility model

In this section of the description, the most preferred embodiment of the utility model will be given, which, however, does not limit other possible embodiments explicitly following from the application materials and understandable to a specialist.

The inventive mattress is manufactured as follows.

They take polyurethane foam (hereinafter referred to as PPU) 10 cm high, 200 cm long, the width is chosen depending on the required width of the mattress. For the manufacture of the mattress, polyurethane foam with a density of 40-55 kg / m ³ is chosen, depending on the model.

A cut is made along the length of the PPU by contour cutting, according to Fig. 2,

where L is the length of the PPU, which is equal to 200 cm, h is the height of the PPU, equal to 10 cm, h ₁ , h ₂ , h ₃ are the contour cutting heights, where h ₁ \u003d 6.5 cm, h ₂ \u003d 7.5 cm , h ₃ \u003d 5.5 cm, L ₁ is the length of the section of the shoulder and pelvic zones, which is 50 cm, measured from the middle of the length of the mattress.

Next, a non-woven needle-punched fiber of 500 g/m ² is glued to the cut points to protect the PPU from springs.

Then, on the cut zone, between two pieces of polyurethane foam with a protective coating, a block of independent springs 5-7 cm high is glued, depending on the mattress model. These springs have the ability to lie exactly on the bends of the cut due to the bending angle up to 180°.

Along the perimeter, the springs reinforce PPU with a density of 40 kg/m ³ .

Next, soft layers are glued onto the top layer of PPU, depending on the model of the mattress, and covered with fabric.

Thus, a mattress with zonal load distribution is obtained.
