Description

The utility model relates to the field of satisfying a person’s vital needs, in particular to furniture, namely, spring blocks for mattresses made of independent springs placed in separate bags of non-woven fabric.

Known spring unit [RU 161990 U1, A47C 23/04, 05/20/2016], for mattresses, containing vertically mounted independent springs placed in separate bags of non-woven fabric, and bags of neighboring springs are interconnected by strips of non-woven fabric.

The disadvantages of such a spring unit are its low density and the absence of the “adaptability” effect under the human body.

Also known is a spring block [RU 2643593 C2, A47C 27/06, 02.02.2018], with a spring enclosed in an individual pocket, comprising a coil spring having an upper end and a lower end, a cover forming a pocket surrounding a coil spring and a shock absorbing pad located above the upper end of the coil spring, the case having a first cell in which the coil spring is placed and a second cell in which the shock-absorbing pillow is placed, wherein the first and second cells are separated from each other.

The disadvantages of this technical solution is the low wear resistance and durability of the structure, as well as the low effect of "adaptability" under the human body.

The closest technical solution to the proposed one is a spring block, [KR 101901889 B1, А47С 27/00, 09/28/2018], containing three types of independent wire springs, placed in separate bags of non-woven fabric and placed in certain zones. Including it contains double independent wire springs, which are wire springs placed in bags of cloth inside which there are additional, also wire, springs placed in their bag, and designed to provide increased rigidity of the edge region of the mattress.

The disadvantage of the closest analogue is the low effect of "adaptability" under the human body, and, as a result, a complex structure containing three types of springs. And the double springs (one in the other) have too much stiffness to place them in the main (central) zone of the mattress, due to the fact that they are both made of metal wire.

Thus, the objective of the proposed utility model is to increase the density of the spring block, while ensuring the maximum effect of "tuning" under the human body and ensuring wear resistance and durability.

The problem is solved by a spring block, which consists of many double springs, each of which is placed in an individual cover made of canvas, surrounding an external metal coil spring. Moreover, each double spring contains an internal shock-absorbing spring made of foamed polyurethane and located inside a metal coil spring. Moreover, the covers surrounding the external metal coil springs are stitched together according to an independent system.

Preferably, the cover is made of cotton fabric and the metal coil springs are made of 1.8 mm diameter wire and have a height of 14 cm.

The technical result of the proposed utility model is to increase the density of the spring block, while ensuring the maximum effect of "tuning" under the human body.

The essence of the utility model is illustrated by drawings.

FIG. 1 - a fragment of a spring block with a spring in a section.

FIG. 2 - mattress with a spring block.

In FIG. 1 shows the design of a spring block containing a series of double springs (1) sewn into individual covers (2). The spring block contains vertically mounted metal coil springs (3), placed in separate covers (2) - bags of fabric. Inside each metal spiral spring (3) shock absorbing springs (4) made of polyurethane foam are placed.

In the spring block, the covers (2) of adjacent double springs (1) are interconnected in an independent system by sewing them together.

The proposed double springs (1), which are a spring (4) of foamed polyurethane installed inside a metal spiral spring (3), provide an increase in the total density of the spring block (Fig. 2). Moreover, the indicated increase in the density of the spring unit due to the use of internal springs (4) made of foamed polyurethane is not excessively large for the entire surface of the mattress (5).

So in the well-known from the source [KR 101901889 B1, А47С 27/00, 09/28/2018] solution, only metal springs are installed, installed in one another, having great rigidity, and, therefore, are suitable only for strengthening the marginal areas of the mattress.

The maximum effect of individual “tuning” under the human body is provided by the proposed unique double springs (1), which are springs (4) of foamed polyurethane installed inside metal coil springs (3).

So in the areas of the mattress (5) experiencing the strongest pressure, the load is perceived by both parts of the double springs (1), thus providing increased resistance. In areas of the mattress (5) where the pressure is minimal, most of this load is absorbed by the internal springs (4) of foamed polyurethane, due to their greatest susceptibility to deformation. In areas of the mattress (5) that experience average pressure values, most of this load is absorbed by external metal coil springs (3).

In addition, the effect of an individual “adjustment” for the human body is also ensured by connecting the covers (2) surrounding the double springs (1) by stitching them together using independent technology. Such a combination of double springs (1) with each other provides an independent perception of loads from the human body, individual on each double spring (1).

In the most preferred embodiment, the proposed spring unit contains 306 pieces per m ² double springs (1), which are a spring (4) of foamed polyurethane installed inside a metal coil spring (3).

The cover (2) surrounding the double spring (1), which is a spring (3) of foamed polyurethane installed inside a metal coil spring (4), is preferably made of cotton fabric, to ensure breathability and ventilation of the internal volumes of the mattress (5).

The outer metal coil springs (3) are preferably made of wire with a diameter of 1.8 mm. The preferred spring height is 14 cm.

In order to improve the performance and environmental friendliness of the mattress (5), the internal springs (4) of foamed polyurethane are made of natural "soy" foamed polymer having a high density.

Thus, in the proposed technical solution, a technical result is achieved, associated with an increase in the density of the spring block, and at the same time ensuring the maximum effect of "tuning" under the human body.
