Description
BACKGROUND OF THE INVENTION
[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.
SUMMARY OF THE INVENTION
[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.

[0035] It should also be noted that anything found to be already

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0036] With reference to the figures, the reference numeral 1
designates a mattress which is constituted at least by a first
structure part, designated by the reference numeral 2, which forms
a containment element made of suitable materials of a known type,
particularly synthetic materials or other, natural materials.
[0037] At least one longitudinal receptacle, designated by the
reference numeral 3, is formed at the containment element, and at
least one second additional part, designated by the reference
numeral 4, and constituted by at least one complementarily shaped
mat, is seated and accommodated detachably therein.
[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 6, and in both elements the
containment element 2 and the mat 4 are assembled and contained by
another outer covering removable fabric 7, which can be accessed by
means of known lateral zip fasteners.
[0044] The longitudinal receptacle 3 can be, as shown in FIGS. 3
and 4, such as to extend only partially into the thickness of the
containment element 2; in this case, a perimetric containment
border 5 is formed for the mat 4, which is as high as the
longitudinal receptacle 3 is deep.
[0045] The mattress 1 can also be of the double type: in this case,
at the containment element, again designated by the reference
numeral 2, there are, at a same side, two longitudinal receptacles,
designated by the reference numerals 3a and 3b, in which it is
possible to arrange detachably mats which are shaped
complementarily and are designated by the reference numerals 4a and
4b.
[0046] The longitudinal receptacles can also be of a type different
than that shown in FIGS. 1, 3, 4, 7 and 8, such as the through
type, shown in FIGS. 5 and 6.
[0047] In this case, the receptacle extends through the entire
thickness of the containment element 2 and, accordingly, the mat 4
or the mats 4a and 4b have the same height.
[0048] Clearly, it is possible to provide embodiments in which, as
shown in FIGS. 7 and 8, the first part and therefore the
containment element, designated by the reference numeral 102, is
made of natural material, while the mats, designated by the
reference numerals 104 and 104a, 104b, are made of synthetic
material arranged at the lower side 106 of the containment element
and therefore at the side on which the body of the user does not
rest.
[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.
