[0001] Various kinds of mattress for human resting are known in the current background art.
[0002] Such mattresses are made by using various known techniques; in some exclusively natural materials, for example wools, horsehair, et cetera, are used, while in some synthetic substances known to the person skilled in the art (for example foamed polyurethane or latex) are used, in others water is used.
[0003] Finally, a mixed solution with outer layers made of natural or synthetic materials between which multiple elastic metallic springs are interposed, also known as a “sandwich” configuration, is known.
[0004] Mattresses with a winter side constituted by wools and a summer side constituted by horsehair or other natural or synthetic materials that are more ventilated are also known.
[0005] All these known kinds of mattress are conceived so as to have permanent characteristics: the same density of material and therefore the same technical characteristics are in fact provided on the entire resting surface.
[0006] This leads to various drawbacks from the standpoint of practical use, since every person has different morphologic characteristics.
[0007] These drawbacks are particularly conspicuous in double mattresses, in which the same density is provided on the entire surface of one side or the other and this technical characteristic makes them usually uncomfortable for one or the other of the persons who rest on them.
[0008] The winter side is in fact often tolerated by some individuals but not by others, and the same applies to the summer side.
[0009] Moreover, a mattress can be too rigid for one person or too soft for another person.
[0010] Such double mattress, moreover, cannot be divided in two in order to expose the side that is most suited to both persons, and therefore a compromise is reached, requiring a variation in the number of blankets used.
[0011] However, these solutions are partial and in any case do not allow good resting and physical comfort.
[0012] Moreover, another drawback is noted which is linked to the size of single and double mattresses: they are in fact rather bulky and difficult to handle, and this for example prevents daily airing of said mattresses.
[0013] Accordingly, the qualitative technical performance options of known mattresses are limited only to two, i.e., to the number of resting surfaces.
[0014] Therefore, if one person has particular requirements he or she is forced to use and store various kinds of mattress through the year, depending for example on the seasons or on particular physical conditions.
[0015] This entails not only a waste of storage volume (which is very limited in modern homes, which are not very spacious) and also a waste of money, since said mattresses are left unused for most of the year.
[0016] The aim of the present invention is to solve the above-mentioned problems, eliminating the drawbacks of the cited known art, by providing a mattress whose technical characteristics can be modified according to the specific requirements of each individual user.
[0017] Within this aim, an object of the invention is to provide a mattress whose characteristics can be modified rapidly and easily.
[0018] Another object is to provide a mattress that is constituted by small parts that are easy to store, replace and sanitize.
[0019] Another object is to provide a mattress that can be aired easily.
[0020] Another object is to provide a mattress that allows the consumer to change its characteristics at low costs.
[0021] Another object is to provide a mattress that allows to reduce the disposal amounts of the product at the end of its life cycle.
[0022] Another object is to provide a mattress that is structurally simple and has low manufacturing costs.
[0023] This aim and these and other objects that will become better apparent hereinafter are achieved by a mattress with diversified density, characterized in that it is modular and is constituted by at least two or more mutually detachably associable parts, at least one first part forming a containment element that has one or more longitudinal receptacles for at least one second part constituted by at least one complementarily shaped mat.
[0024] Further characteristics and advantages of the invention will become better apparent from the following detailed description of a particular embodiment thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
[0025]
[0026]
[0027]
[0028]
[0029]
[0030]
[0031]
[0032]
[0033]
[0034] In the examples of embodiment that follow, individual characteristics, given in relation to specific examples, may actually be interchanged with other different characteristics that exist in other examples of embodiment.
[0035] It should also be noted that anything found to be already known during the patenting process is understood not to be claimed and to be the subject of a disclaimer.
[0036] With reference to the figures, the reference numeral
[0037] At least one longitudinal receptacle, designated by the reference numeral
[0038] The mat is made of various synthetic or natural materials that are suitable for the purpose, such as wools, horsehair, alpine herbs, mountain pasture hay, et cetera and are adapted to determine overall density variation or density variation at selected points or regions of the resting surface.
[0039] The mat can be removed, replaced, aired and sanitized easily, indeed because of its reduced dimensions, which make it easy to handle.
[0040] Indeed because of this characteristic, it can be stored easily even in wardrobes, so that it is possible to store the various types, each composed of various materials that can be used in each instance according to personal requirements.
[0041] This makes the mattress as a whole more versatile.
[0042] In this manner, with a single containment element it is possible to have as many different solutions for the user's resting as there are types of mattress usable.
[0043] Clearly, the elements are appropriately covered individually with suitable removable fabrics
[0044] The longitudinal receptacle
[0045] The mattress
[0046] The longitudinal receptacles can also be of a type different than that shown in
[0047] In this case, the receptacle extends through the entire thickness of the containment element
[0048] Clearly, it is possible to provide embodiments in which, as shown in
[0049] It has thus been found that the invention has achieved the intended aim and objects, a mattress having been obtained in which the containment element has a longitudinal receptacle formed preferably in a recessed central region that is adapted to receive various kinds of interchangeable mats, such containment element forming a supporting structure, while the mat is of an easily replaceable, interchangeable type, which is compact and in any case suitable to ensure resting quality.
[0050] Such mattress can be handled easily and therefore easily placed to air, and can be washed periodically, if allowed by the internal material, in order to improve its hygiene.
[0051] The mattress thus provided can in turn be inspected with great ease in order to assess the efficiency of its various components, allowing their airing, or the replacement of the damaged parts.
[0052] Moreover, the mattress in the double version, together with the individual mats, can be accommodated inside the containment fabrics or inside external covering fabrics, which have optional suitable zip fasteners that allow easy and immediate access thereto.
[0053] The removable and replaceable nature of the individual mats allows to choose to sleep according to two distinct or different technical characteristics, which can be customized on each side of the mattress simply by choosing the mat that has the intended characteristic.
[0054] As an alternative, the double mattress can be constituted by two separate and individual mattresses, mutually coupled by way of known coupling means, or simply arranged side by side, and kept associated to each other by means of an individual outer case.
[0055] Moreover, the dimensions of the mats allow their easy storage even in conventional wardrobes, which have minimum depths of sixty centimeters.
[0056] Therefore, the illustrated solution allows to provide a mattress whose density and technical performance can even be different at the individual surface or resting side, by way of the difference in consistency between the containment element and the mats.
[0057] The invention is of course susceptible of numerous modifications and variations, all of which are within the scope of the same appended claims.
[0058] The materials used, as well as the dimensions that constitute the individual components of the invention, may of course be more pertinent according to specific requirements.
[0059] The various means for performing certain different functions need not certainly coexist only in the illustrated embodiment but can be present per se in many embodiments, including ones that are not illustrated.
