PURPOSE OF THE INVENTION
[0001] This description refers to a patent applied for, and relates to a new improved thermic
mattress, whose purpose is clearly to be used as a conventional mattress that presents
a suitable internally built-in flexible electric resistance protected by a layer of
silicone, introduced for security purposes and which will act as a heat generator.
The flexible electric resistance instead of being built-in to the mattress can be
built-in to a flexible sheet over the upper layer of the mattress, managing in the
same way to generate the pertinent heat as a comfort to the user.
SCOPE OF THE INVENTION
[0002] This invention is for use within the mattress manufacturing industry, and might be
partially used by the electric resistance manufacturing industry.
BACKGROUND OF THE INVENTION
[0003] The applicant is aware of the existence at present of a number of blankets and similar
products which apply heat to the user plugged into conventional electricity supplies.
[0004] These mattresses, pillows or similar, usually of a smaller size, have a power regulator
which permits the user variation of temperature.
[0005] Generally-speaking, the heat generators are in the form of electrical resistances
suitably protected and introduced into the interior of the various layers of fabric
of which the blankets and other are made-up.
[0006] In addition to the existence of this type of electrical coverlets used as heat generators
for human use, independent of if for use on top of the upper part of the mattress
for receiving heat, the applicant is aware of the existence of mattresses which include
over the "winter side" of the mattress interconnected resistance/-s which generate
heat, similar to the type incorporated in the coverlets, blankets, etc., etc.
[0007] It has been verified that the use of this type of resistance for mattresses on which
one lies down for long periods of time cause a gradual wear and tear of the materials
used in conventional resistances, damaging the same and, subsequently, the body of
the mattress, detrimental to the comfort of the user.
[0008] Also, it should be borne in mind that the mattresses which include the previously
mentioned resistances, and these mattresses are used by children which normally do
not contain miction, imply a risk for the user, or when the user applies a notable
amount of dampness to the mattresses (perspiration).
[0009] The obvious solution to the problem that exists at present would be to have available
a mattress which includes a flexible electrical resistance with a factor of security
which would avoid the above-mentioned risks and, at the same time, given its characteristics,
the comfort for the user would not be affected during the use of the mattress.
[0010] However, the applicant is not aware of the existence at present of a mattress of
these ideal characteristics.
DESCRIPTION OF THE INVENTION
[0011] The new thermal improved mattress which the invention offers, constitutes in itself
a clear novelty within the field of application of the same, given that from the introduction
of a flexible electrical resistance adequately protected with a layer of silicone
in the new mattress, the same can be considered as having all the characteristics
indicated as ideal.
[0012] More specifically, the new improved thermic mattress, subject of this invention,
constitutes a conventional mattress, which could have a central upper area, within
a flexible, electric sheet able to be placed on the upper layer of the mattress and
including a flexible electrical resistance protected by a layer of silicone for security
purposes with a controlled power of 220 voltage and likewise a two-way switch of optional
use which allows heating of 50% of the surface.
[0013] The invention has been formed iii such a way that the resistance can be assembled
on the upper middle face of the mattress and in such way provide its heating capacity
without being detrimental to comfort.
[0014] Externally the mattress will have an entirely conventional aspect in accordance with
the taste and choice of the user and based oil a determined type of mattress.
[0015] In short, the invention can be formed as a resistance introduced in the interior
of the mattress. That is to say, assembled over the upper middle face, or be introduced
as an additional element which is added to, stuck to or fixed on one of the sides
of the mattresses situated in the interior of a flexible sheet, which will be fixed
to the mattress by conventional means to prevent movement.
[0016] In both cases the resistance placed in the interior of the mattress, or additional
electrical sheet, will bear a switch for heating two separate areas which are understood
to be the whole area of the mattress or sheet or, in the event, 50% of the area.
DESCRIPTION OF THE DRAWINGS
[0017] As a complement to the description which is to be realised and in order to provide
a better understanding of the characteristics of the invention, illustrated, non-limiting
drawings are attached to this report, and form all integral part of the same and are
as follows:
Drawing 1: Shows a raised side view of a conventional mattress in the interior of
which -on the upper middle layer- a flexible electrical resistance is introduced,
forming as a result a first realisation of the invention of a new improved thermic
mattress.
Drawing 2: Corresponds to a view of A-B of figure 1.
Drawing 3: Shows a view of C-D of figure 2.
Drawing 4: Corresponds to a raised side view of a second realisation of the invention
in the form of a flexible, elastic sheet on the surface of the mattress.
PREFERENTIAL REALISATION OF THE INVENTION
[0018] In view of drawing 1, it can be observed how the new improved thermic mattress is
formed from the introduction in the interior of the conventional mattress (1) -on
the upper middle layer- a flexible electrical resistance protected by a layer of silicone
for security purposes and a controlled power of 220 voltage which has an optional-use
switch (6), so that the resistance (2) generates heat over all the surface area, or
an area understood to be 50% of the whole.
[0019] Passing to figure 2 it can be observed how the electrical resistance (2) has a covering
of silicone (4) over the metal core (5) of the resistance (2), specifically indicating
that the power is controlled at 220 wats.
[0020] In the second realisation, represented by figure 4, it can be observed how the resistance
(2), introduced in the interior of the flexible elastic sheet (10) can be assembled
in a direct manner over one of the two larger sides of the mattress (1), fixed (in
such a way that it cannot slip) to the body of the mattress by conventional means
forming a single block between the mattress (1) and the flexible sheet (10). Or optionally
this flexible sheet can be fixed over the face of the mattress (1) through conventional
means.
[0021] The temperature of the resistance obtained is 60°C, due to its response to the following
factors:
Lt=n.L1=6x1.5=9mts. W=10 mts/mx9 = 90wts. At=16°C
[0022] It is not considered necessary to enlarge this description as any expert on the subject
might understand the scope of the invention and the advantages that the same offers.
[0023] The material, form, size and layout of the elements are liable to variation, but
only when the same does not signify a change in the essential part of the invention.
[0024] The terms of this report should be at all times considered as ample and non-limiting
1. New improved thermic mattress based on the use of a conventional mattress (1), special
because on the middle layer of the mattress (1) a flexible electrical mattress is
introduced (2) protected by a layer of silicone (4) and a controlled power of 220
wats, with a switch (6), optionally included for the determination of 2 areas in which
the resistance works (2).
2. New improved thermic mattress, in accordance with the first claim, whose special characteristic
is the flexible electric resistance (2), protected by a layer of silicone (4), generating
heat over all the working area, or half, by means of a switch (6).
3. New improved thermic mattress, in compliance with the previous claims, singular because
in a second performance the electric resistance (2), protected by a layer of silicone
(4), can be optionally introduced within a flexible electric sheet (10), located on
the layer or upper face of the mattress (1).
4. New improved thermic mattress, as indicated in point 3, singular because the flexible
sheet (10) can be placed over the mattress (1) forming a fixed single block through
conventional means, or the flexible elastic sheet (10) can be fixed on the mattress
(1) by conventional means allowing mobility.
