Description

DESCRIPTION

MATTRESS WITH HYBRID CORE OF FOAM AND SPRINGS

Object of the invention

The object of this report is a mattress with a hybrid core of foam and springs, which is characterized by being formed by means of a hybrid core in which flexible polyurethane foams are combined with a pocket spring shell, which allows a good sleeping posture. , with a pleasant reception to which a visually attractive design can be added.

Background of the invention

At present, the core formed as the internal part of the mattress is in charge of providing ideal support for the body and thus guaranteeing its rest. Thus, depending on the type of core, the rest varies, and it can be made of foam, viscoelastic (mattresses with flexible polyurethane foam cores) or springs.

Said types of cores and, therefore, of mattresses currently make up the vast majority of rest solutions present in the state of the art, however, the applicant is aware of mattresses with mixed cores that try to improve the benefits for the rest, optimizing its results through the integration of various technologies.

However, these types of solutions are based on placing foams in the core as mere layers of adaptability, not being considered as an integral part of it.

The applicant is aware of the existence of various documents that reflect the state of the art, thus, Spanish patent ES 2 632 255 describes a core for mattresses and pillows of different firmness characterized by being composed of between 20 and 90 kg/m3 of viscoelastic and the incorporation of a spring of plastic or metal and/or a polyurethane foam padding of between 20 to 60 Kg/m3 placed in the central hole of the elastic core.

Similarly, Spanish patent ES 2234 410 describes a spring mattress made of polyurethane foam, characterized in that the main body is made of a single block of said material and has springs with variable flexion resistance; and because the springs of said mattress have coils that are shaped by cutting the aforementioned block with a specific machine and expelling the excess material; and where the springs have a different number of coils distributed depending on the area of the mattress and the distribution of a person's body, in order to vary the resistance to bending of said springs and consequently of the mattress.

Similarly, patent ES 2323 279 T3 describes a bed mattress that includes a set of springs consisting of a plurality of springs arranged in row and column directions over the entire area of the bed mattress, and a helical coil to securely engage the springs to each other, wherein the bed mattress consists of: a reinforcing pervious element provided on an upper surface and/or on a lower surface of the spring assembly, the reinforcing pervious element being formed by a one-layer structure single or multi-layered; and a foam material; located on the outer surface of the permeable reinforcing element to be foamed, wherein the permeable reinforcing element is embedded within the foamed material and at the same time the spring assembly and the foamed material are integrally formed with each other by foaming the foamed material passing through a plurality of fine holes in the reinforcing permeable element; characterized in that the permeable reinforcing element is further formed by a plurality of holes for foam expansion arranged along the directions in rows and in columns such that they are spaced apart from each other at regular intervals so that a part of the foam material enters the interior of the set of springs in an increasing amount through the holes for the expansion of the foam, to be convexly foamed and a joint part between a spring of the set of springs and a helical coil and preferably a part of the seam between the springs or a part of the space between the springs are embedded within the convexly foamed part of the material sparkling.

None of the solutions described here solves the problem described as does the invention proposed here, that is, a mattress essentially made up of a hybrid core in which flexible polyurethane foams are combined with a pocket spring casing, which allows better posture for rest, adapting to all areas of the user's back in a simple and comfortable way.

Description of the invention

The technical problem that the present invention solves is to achieve a mattress that optimally adapts to the user's back to provide a lasting and real rest thanks to its adaptability to the contour of the user's back. For this, the mattress with a hybrid core of foam and springs, object of the present invention, is characterized by comprising a core that in turn is divided into three zones: where the first one is materialized in a polyurethane foam; the second is made up of a plurality of springs reinforced with polyurethane foam, and the third by another layer of polyurethane foam; and where the polyurethane foam used in the first zone has a density of between 25 and 35 kg/m3 with a hardness of between 6 and 10 KPas; the density used in the second area for the reinforcement of the springs is between 23 and 30 kg/m3 with a hardness between 5 and 9 KPas; and finally, the density of the foam used in the third zone is between 25 and 31 kg/m3 with a hardness between 3 and 5 KPas.

Thanks to its design, the mattress is configured using a hybrid core between polyurethane foam and springs, in such a way that an integral core is created that works as a single body; although thanks to its special shape, it generates up to seven independent comfort zones that provide the appropriate firmness for each part of the user's body, providing a greater sensation of comfort and better rest.

This is achieved thanks to a careful choice of materials and the densities used, specifically designing a series of profiles that take into account the level of firmness offered by each material, the areas of the body that will rest on it and the level of firmness necessary in each of them to ensure a good posture.

The foam used has been selected in the first place to ensure good performance and long durability, allowing its coloring to increase the visual impact it offers, and, therefore, giving a better optical performance to the product, a fact of special importance (along with with the quality of rest) when facing a sale in the market.

Finally, said core especially protects the pelvic area and the cervical/dorsal area; since they are the areas of the body that require greater firmness when exerting greater pressure on the mattress (avoiding excessive sinking and ensuring alignment of the spine, if the user chooses to sleep on their side).
