    DESCRIPTION
    Improved mattress core and mattress with said core
    The present invention relates to a new technology applied to the core of a mattress and to mattresses comprising said core.
    The mattress core should be understood as the internal part of the mattress that acts as a support, giving the mattress assembly its characteristic firmness. One or more layers with different comfort benefits are added to the core. The core is, therefore, the main component of the mattress. Five types of mattresses are currently known based on the different types of core: spring mattresses, foam mattresses, latex mattresses, air mattresses and water mattresses. In the case of spring mattresses, the core consists of a series of helical springs joined together. In the case of foam and latex mattresses, the core consists of a piece of said material, while in the case of air and water mattresses the core is a bag that receives the fluid in question (air or water ).
    However, despite these being the technologies that dominate the sector for years as components that make up the mattress core, the reality is that they lack some characteristics that would be highly valued within the sector.
    One of them would be the recyclability of the mattress core. Today, only the spring cores are recyclable, which is a problem when closing the product's life cycle and complying with the regulations that are increasingly stringent in terms of environmental terms, and that foresee stricter in the future.
    It is therefore an object of the present invention to present a new technology for mattress cores that presents the possibility of recyclability once its life cycle has ended, as well as zoning and comfort adjustment.
    In addition, the present invention allows the configuration of a customizable mattress firmly according to the needs and tastes of the end user.
    The present invention moves away from the structures traditionally used as the basis for the construction of the mattress support. Consequently, the present invention proposes the use of materials with elastic properties, preferably plastic, in the form of parts, in particular profiles, which can be obtained by an extrusion process. An additionally innovative concept of the present invention resides in the use of hollow pieces of a flexible plastic material for obtaining a mattress core.
    More particularly, the present invention is based on the use of constant section profiles that have an elastic element that allows the distance between the bases to be modified. The variation of distance between bases allows to take advantage of the flow of air in and out of a chamber to regulate the response of the mattress.

    Especially advantageously, the profiles comprise a lower base and an upper base. The upper base acts as a receiver of the user's weight and the lower one of support, and at least one wall that joins them. Preferably, said wall has an elastic element of variable length, such that the variation in length of the elastic element modifies the distance between said lower and upper base.
    According to one aspect, the present invention discloses the obtaining by extrusion of profiles of a profile such that hollow channels are defined that house a gas therein, advantageously air. The main core of the mattress may be formed by a certain number of extruded profiles (in varying numbers depending on the size of the mattress) joined together by clipping or other fixation. The present invention also provides that the profiles are obtained jointly in the same extrusion process.
    More particularly, the present invention discloses a mattress core comprising a plurality of constant section profiles in which the profiles are made of an elastic material, each profile comprising a lower base and an upper base and at least one wall which joins them and which defines a chamber filled with air or other gas and that comprises an elastic element of variable length, such that the variation in length of the elastic element modifies the distance between said lower and upper bases.
    Preferably, said elastic element comprises at least one wall connecting said lower and upper bases and whose development between both bases has a component not perpendicular to the bases.
    More preferably, said wall comprises a cylindrical wall, said cylindrical wall defining said chamber.
    In a particular embodiment, each profile can also comprise additional wall sections to the cylindrical wall and joining said upper and lower bases. Said wall sections may be sections that directly link both upper and lower bases, or sections that join the cylindrical wall with said upper and lower bases.
    The profiles may be linked together, or separated, or grouped in blocks.
    Advantageously, the profiles can be joined together through said additional walls, leaving the upper and / or lower bases between profiles.
    In one embodiment, at least one of the profiles is open to the outside at its ends, such that air can flow freely through its interior and through its ends.
    The present invention also allows at least one of the profiles to have caps at their ends.
    The core object of the present invention may have a section made exclusively of said profiles.
    In accordance with the present invention, said profiles may be extruded profiles. This allows for easy manufacturing, and the result is elastic profiles, of constant section, closed by their sides and open

    by its ends. These types of profiles, due to their structure, provide a comfort response unknown to date.
    The profiles of the core object of the present invention may be arranged longitudinally or transversely with respect to the main or greater length of the mattress. In the longitudinal arrangement, each profile is arranged along said main length. The transverse arrangement is perpendicular to this.
    Through a longitudinal configuration of profiles, a uniform pressure distribution can be achieved, approaching the ideal case of isobar lines in a static situation of the sleeper. The block object of the present invention can be divided into completely isolated chambers whose longitudinal dimension is much larger than the cross section.
    The present invention also has the advantage that the profiles joined together exert a low influence of movement in the direction perpendicular to the profiles. This has as a consequence that each profile performs its function with little influence on adjacent profiles. This allows, especially in this configuration, to isolate the respective support of two sleepers arranged on the same mattress, obtaining what in the sector is known as bed independence.
    The material that forms the profiles, as well as their geometry, has an important influence on the behavior of the whole. Consequently, this property can be used to implement areas with different stiffness depending on the material and the profile design. A cross-sectional configuration of profiles is useful to achieve greater adaptability to the sleeper's body contour, creating different zones.
    As for the ends of the profiles, the present invention provides two main aspects: a first, in which the profiles are open at their ends. In this case, core comfort is achieved thanks to the elastic properties of the material with which the profile has been extruded. A second aspect in which the ends of the profile have flow control means that are sealed so that the air is also used for comfort, since they form a hermetic chamber.
    In this last possibility, the profiles can be connected to each other, in addition to sealing, by means of a valve system (even pump) so that the air pressure is equalized at all points and if necessary, even being able to control it, getting a configurable comfort core. By controlling the air pressure inside, the firmness of the profile is controlled, which will result in a configurable comfort.
    Once developed the configuration of different profiles of elastic material that cover the entire surface of the mattress and that makes up the core, to this core you can add the rest of the components that make up the parts of a mattress (padded covers, sides, covers, etc.). However, given the technological novelty of the present invention, the mattress core constructed in this way could have an aesthetic totally different from what exists in the market.
    Being a core formed by extruded profiles of thermoplastic elastic material (PVC, TPE, SBS, etc.), it is a fully recyclable core since these materials can later be reused.

    In a preferred embodiment, the core comprises a first zone with said profiles and a second zone with helical springs or foam or latex or air or water mattress.
    More preferably, the first zone and the second zone are configured as two overlapping layers.
    The present invention also comprises mattresses with the core object of the present invention.
    For your best understanding, some drawings of an embodiment of the object of the present invention are attached by way of explanatory but not limiting example.
    Figure 1 shows a perspective view of an example of mattress core section extrusion profile of elastic thermoplastic material usable according to the present invention.
    Figure 2 shows a top plan view of the embodiment example of Figure 1.
    Figure 3 shows an elevation view of the example.
    An example of a mattress core section composed of a plurality of profiles -1- usable in the present invention is shown in the figures. The profile of the example can be realized by extrusion of a plastic material, preferably thermoplastic, elastic. Profile -1- is a hollow profile of essentially constant section. Profile -1- has two bases -11-, -12-, which can be referred to as upper base -11- and lower base -12-. The bases are connected to each other by a tubular wall -501-, of elastic material. The tubular wall has a development between bases with a component perpendicular to the bases and another parallel component, which increases the elastic response. In addition, the tubular wall defines an interior space for air or gas.
    In particular, profiles -1- of the core sector shown comprise an upper base -11- and a lower base -12-. Both the upper base -11- and the lower base -12- are horizontal, the upper base -11- being the one to receive the load and the lower base -12- supports the core. The bases -11-, -12- of each profile -1 - are not directly attached to the bases of the adjacent profiles, so that each upper base -11- can move vertically without affecting the adjacent base. The bases -11-, -12- of each profile of the example are joined together by two side walls -13- and -14- and by a tubular wall -501 - which is located between both side walls -13-, -14 -. The side walls -13-, -14- are optional and may have variations in their design. The side walls -13-, -14- are slightly warped to favor elastic behavior, that is, allow the variation of the distance between the upper base -11- and the lower base -12-. This is due to the existence of wall pieces that are not strictly perpendicular to the bases, but oblique to them. Similarly, the cylindrical wall is continuous and provides an elastic function and generates a chamber -502- intended to contain air or other gas. Since it is the walls that join the bases that provide the elastic response, the variation in volume produced by the approach or distance of the bases from each other can be used to regulate the hardness of the elastic response or to provide a damping component to The elastic response. If the air chamber is left (defined in this case by the tubular wall -501 -) open at its ends, a soft behavior is obtained and with hardly any damping. If their ends are covered, for example, using caps -2-, a hard behavior is obtained. If obstacles are placed for the air inlet / outlet (for example by providing a hole to the cover -2-) (no

    shown in the figures), a dampened behavior is obtained, by combining elements such as valves different behaviors can be obtained for compression and decompression (emptying / filling with chamber air). The pressure of the chambers can also be regulated by means of a pump. In these cases, the behavior of the profile is, to a certain extent, similar to that of an air mattress, with the exception of having an additional elastic behavior because the force exerted by the core is not an exclusive function of the fluid pressure. However, when the ends of the profile are open, there is only an elastic behavior, as in the spring mattresses.
    Finally, the side walls -13, -14- of adjacent profiles are joined together by horizontal bridges -503-.
    As indicated, the side walls -13-, -14- may have different designs. It is also possible to make the tubular wall -501 - not directly attached to the bases -11 -, -12-, but through sections of the connecting wall to the upper base -11- and wall sections connecting to the bottom base. In this case, the chamber can be defined exclusively by the tubular wall -501- or by the set of sections of cylindrical wall and said connection walls.
    The combination of different profiles allows to obtain a core with zoned firmness. Thus, for example, groups of profiles made of plastics with different elastic modulus or with different side wall thicknesses can be alternated.
    From the core shown in the example it is possible to obtain mattresses covering the core with various layers of comfort, which could be of known type, or of any other.
    The profiles object of the present invention can generate a core with multiple chambers. In turn, the profiles may be single chamber (a single space for gas / air) or multi-chamber (various spaces).
    Although the invention has been presented and described with reference to embodiments thereof, it will be understood that these are not limiting of the invention, so that multiple constructive or other details that could be evident to the technicians of the sector could be variable after Interpret the subject matter disclosed in the present description, claims and drawings. Thus, all variants and equivalents will be included within the scope of the present invention if they can be considered to be within the broadest scope of the following claims.
