[0001] The present invention relates to devices for forming a structure, typically to elements
that are arranged between the panels of a structure for the purpose of cooling, heating
or fluidic treatments in general, which therefore must provide effective thermal insulation
between the environment inside and outside the structure.
[0002] Such devices typically have one or more metal profile elements, which can be connected
to the panels, or walls, of a structure.
[0003] Although different solutions of such devices are known, they typically lack adequate
thermal insulation capacity.
[0004] Object of the present invention it is therefore to provide a device and related structure
which are easy to manufacture while providing effective thermal insulation between
the inside and the outside of the structure.
[0005] These and other objects are solved by a device and a structure according to one or
more of the appended claims.
[0006] In particular, a device and a structure according to claims 1 and 8 are object of
the present invention, while preferred aspects are set forth in the dependent claims.
[0007] Specifically, according to an aspect of the present invention, a device for forming
a structure, connectable to at least one wall of the structure, comprises a first
and a second metal profile, the first metal profile defining in section at least one
first closed chamber, the second metal profile defining in section at least one second
closed chamber. The device comprises a polymer insulating element interposed between
the first metal profile and the second metal profile, where the first profile, insulating
element and second profile are arranged in series so as to prevent the contact between
the first profile and the second profile.
[0008] Profiles are elements made in a manner known in the art and are typically single,
one-piece elements that therefore form two or more closed chambers.
[0009] Metal profiles and polymer insulating element are arranged in series, that is, in
a linear series, one after the other in the same direction, like the links of a chain
(without, of course, an intersection of the respective chambers), in which the polymer
insulating element is interposed between the metal profiles.
[0010] According to an aspect of the invention, such metal profiles can each be made in
one piece.
[0011] The first and second metal profiles, according to another aspect of the invention,
actually form a sequence of two or more closed chambers arranged in series, preferably
in a linear series, that is to say preferably aligned, one after the other along the
same direction which connects the inner space to the outer space.
[0012] The second profile, arranged in use toward the inside of the structure, has at least
one chamber adapted to provide a first thermal insulation. The profile is effectively
hollow and is therefore filled with air in use or possibly filled with insulating
material, which provides a first function of thermal insulation.
[0013] Additionally, the device has an additional insulating element, which is an element
made of material thermally less conductive than the material of the metal profiles.
By preventing the contact between the two metal profiles, this insulating element
made of polymer material prevents direct heat transmission between the two elements.
[0014] The first metal profile, arranged in use toward the outside of the structure, also
has a chamber that provides an additional insulating function due to the ambient air
contained therein.
[0015] At least part of the second profile, typically at least part of the second device
chamber made in the second profile, is covered with a polymer cover.
[0016] Such cover helps to improve the insulation efficiency of the device.
[0017] The polymer cover can also be arranged so as to ensure that the entire side, facing
the inner space, of the second chamber of the second metal profile is covered and
preferably enclosed by the polymer cover in order to further improve the insulating
efficiency of the device.
[0018] For this purpose, the polymer cover preferably forms openings configured to form
a plurality of air chambers between the polymer cover and the second profile.
[0019] Preferably, the first profile comprises exactly one closed chamber and/or the second
profile forms exactly one or two closed chambers. This provides a good compromise
between compactness, simplicity and insulating function of the device.
[0020] According to a preferred aspect, the polymer insulating element is in contact with
the second chamber of the device.
[0021] According to a preferred aspect, the insulating element comprises two portions separated
from each other and interposed between the first and second profiles.
[0022] An object of the present invention also relates to a structure comprising at least
one device according to one or more of the preceding aspects and at least one wall
constrained to the device.
[0023] According to a preferred aspect, the structure defines at least one inner space and
one outer space of the structure, in which the first profile faces the outer space
and the second profile (or anyway the polymer cover applied thereto) faces the inner
space.
[0024] According to a preferred aspect, the wall comprises two metal sheets connected to
each other by at least one polymer profile. The device is connected to the polymer
profile and/or at least one of the metal sheets, preferably by at least one connection
selected from: at least one screw connecting said polymer profile of said wall to
said second metal profile of said device; a hinge connecting said first metal profile
of said device to one of the metal sheets of said wall; retainers arranged with interference
between said first metal profile of said device and one of the metal sheets of the
wall.

[0026] A device 1 for forming a structure 10 comprises a first and a second metal profiles
2, 3.
[0027] The first metal profile 2 defines in section at least one first closed chamber 4,
while the second metal profile 3 defines in section at least one second closed chamber
5.
[0028] The metal profiles 2, 3 are one-piece elements made, for example, by extrusion. Specifically,
in the case where the first metal profile 2 or the second metal profile 3 has two
or more chambers, such metal profile is a single element that forms in section these
two or more chambers.
[0029] The preferred material for the metal profiles 2, 3 is aluminum or at least an aluminum
alloy.
[0030] In preferred embodiments, the first profile 2 forms exactly one closed chamber 4,
while the second metal profile forms two closed chambers 5, 6.
[0031] In other embodiments, the number of chambers of the metal profiles 2 and 3 can be
variable for each profile.
[0032] It should also be noted that these first and second metal profiles 2, 3 can each
be made in one piece, for example from aluminum.
[0033] The device 1 further comprises a polymer insulating element 7 interposed between
the first metal profile 2 and the second metal profile 3.
[0034] The polymer insulating element 7 can take different shapes in different embodiments.
In general, the polymer insulating element 7 is shaped so as to prevent the contact
between the first metal profile 2 and the second metal profile 3.
[0035] The polymer insulating element 7 preferably has two portions 7a, 7b arranged distal
to each other, considering the sectional view of the device. The two portions can
be elements separated from each other or they can be connected to each other, such
as by a transverse portion connecting the two portions 7a, 7b. The two portions 7a,
7b are typically essentially identical and are arranged in a specular manner in the
device, typically with respect to a plane passing through both the metal profiles
2, 3.
[0036] Preferably, the two portions 7a, 7b are arranged to form a chamber 7c with the metal
profiles 2, 3. The two portions 7a, 7b themselves and outer walls of metal profiles
2, 3 constitute the walls of this chamber 7c. According to a possible aspect, considering
the sectional view of the device 1, each portion 7a, 7b is arranged substantially
flush with a wall of at least one of the two metal profiles 2, 3, preferably with
both a wall of the first metal profile 2 and a wall of the second metal profile 3.
[0037] The connection between the portions 7a, 7b and the metal profiles 2, 3 can be made
in different ways. According to a preferred aspect, the ends of the portions 7a, 7b
are coupled by interlocking in corresponding seats made on the outer surface of the
metal profiles 2, 3.
[0038] In general, the polymer insulating element 7 makes it possible to avoid direct heat
transmission between the two metal profiles 2, 3.
[0039] Polymer materials are typically thermally insulating, so different polymer materials
can be used to make the polymer insulating element 7. The Applicant found that insulating
elements 7 made of polyamide provided a good compromise between mechanical and thermal
properties.
[0040] The metal profiles 2, 3 and the polymer insulating element 7 are arranged in series,
with the polymer insulating element 7 arranged between the two metal profiles 2, 3.
[0041] Considering the section of the device, the metal profiles 2, 3 are arranged opposite
each other, with respect to the polymer insulating element 7.
[0042] In a possible embodiment, as discussed, the second profile has exactly two closed
chambers 5, 6, specifically the aforementioned second chamber 5 and an additional
third chamber 6. Therefore, the third chamber 6 is in contact with the polymer insulating
element 7, whereas the second chamber 5 is opposite the polymer insulating element
7 with respect to the third chamber 6.
[0043] The second chamber 5 has at least one surface directed toward, and facing, the inner
space of the structure 10 and at least one opposite surface facing the third chamber
6.
[0044] The size of the second chamber 5 (i.e., the area of the closed figure formed by the
second chamber 5) is typically larger than the third chamber 6 of the second metal
profile 3.
[0045] In this embodiment of the invention, the first and the second metal profiles 2, 3
actually form a sequence of two or more closed chambers 5, 6, 4 arranged in series,
preferably in a linear series, that is to say preferably aligned, one after the other
along the same direction which connects the inner space to the outer space of the
structure 10.
[0046] According to an aspect of the invention, at least the closed chambers 5, 6 of the
second profile 3 are aligned with each other, in series, along the direction joining
the inner space to the outer space of the structure 10.
[0047] According to a preferred aspect, at least part of the second metal profile 3, typically
at least part of the second chamber 5 of the second profile 3, is covered with a polymer
cover 8. Such a cover 8 is arranged to preferably cover at least the walls of the
second metal profile 3 which, in use, face the inside of the structure 10.
[0048] In general, the polymer cover 8 helps to improve the insulation efficiency of the
device.
[0049] According to a further preferred aspect, the cover 8 can be applied so that at least
the entire inwardly facing side of the second chamber 5 of the second metal profile
3 is covered and preferably enclosed by the polymer cover 8 in order to further improve
the insulating efficiency of the device.
[0050] In other words, at least the entire inwardly facing surface of the second chamber
5 of the second profile 3, that is at least the entire surface of the chamber 5 which
is intended to face the inner space of the structure 10, is preferably covered by
the polymer cover 8, so that the latter can effectively act as a thermally insulating
barrier with respect to this second chamber 5 and thus with respect to the entire
device 1.
[0051] The cover 8 can be applied to the second profile 3 by means of different technologies,
such as by mechanical constraint or adhesion or gluing.
[0052] Various materials can be used. Preferred solutions use a cover made of PVC (polyvinyl
chloride), so that the cover 8 is provided with thermal insulating properties as well
as antibacterial properties.
[0053] According to a preferred aspect, the polymer cover 8 has recesses 8a configured to
form a plurality of air chambers between the body of the polymer cover 8 and the second
profile 3, when the former is constrained to the latter.
[0054] As discussed, the device 1 is preferably used in a closed structure 10 equipped with
a plurality of walls 11 typically in the form of panels. The devices 1 are typically
arranged next to at least part of the uprights 10a of the closed structure 10. In
preferred embodiments, they are arranged at both the uprights 10a and the crossbeams
10b of the structure 10.
[0055] According to an additional preferred aspect, a gasket 17 is provided between the
device 1 and the wall 11.
[0056] The gasket 17 typically seals the space between the device 1 and the wall 11 and
is preferably arranged between the polymer cover 8 and a metal sheet 11b of the wall
11.
[0057] Specifically, the gasket 17, preferably made of polymer material, is arranged toward
the inner space of the structure 10 and increases the thermal insulating efficiency
of the inner space of the structure 10 with respect to the environment around the
structure 10 itself.
[0058] According to yet another preferred aspect, there is a sealing element 18 positioned
between the polymer profile 12 and the second profile 3, preferably coupled to the
second chamber 5 of said profile.
[0059] This sealing element 18 ensures better sealing in the presence of liquid, for example
as a result of condensation.
[0060] Finally, according to a further preferred aspect, the device 1 comprises exactly
two metal profiles 2 and 3.
[0061] In use, the chambers 4, and 5 of the metal profiles 2, 3 are typically hollow, that
is, they do not have fillers. Therefore, inside these chambers 4 and 5 there is, typically,
ambient air.
[0062] However, in alternative embodiments, the presence of insulating material within said
chambers is not excluded.
[0063] As discussed, the walls 11 are preferably in panel form. Specifically, in particularly
advantageous solutions, the walls have metal sheets 11a arranged substantially parallel
with each other and connected together by at least one polymer profile 12, typically
four polymer profiles 12.
[0064] Specifically, in the most basic solution, a wall 11 of the structure 10 has a substantially
rectangular section, in which the metal sheets 11a form the long sides of the rectangle,
whereas the polymer profiles 12 are arranged at the two short sides of the rectangle.
At each of the upper and lower ends of the wall 10 there is an additional polymer
profile 12, which is adapted to constrain together the walls 11a, 11b at these ends.
[0065] In general, an inner space 11c of the wall, i.e. a chamber inside the wall, is defined
by the metal sheets 11 and the polymer profiles 12. This inner space 11c is typically
filled, preferably with insulating material. In possible embodiments such an insulating
material comprises a mineral material, such as rock wool. Different solutions are
possible, for example by using a polymer foam material as insulating material.
[0066] The metal sheets 11a, 11b are typically folded at the ends. These ends are typically
inserted within special seats (slits) of the polymer profiles 12. In possible embodiments,
connecting elements, such as screws, rivets or the like, could be used to constrain
the metal sheets 11a, 11b to the polymer profiles 12 at these seats. Alternatively
(particularly in embodiments using a polymer foam material as insulating material),
the coupling between the metal sheets 11a, 11b and the polymer profiles 12 at the
seats, typically with the aid of the insulating material, is sufficient to ensure
effective coupling between the elements.
[0067] The polymer profile 12, typically made by extrusion, typically forms a closed chamber.
Various materials can be used. In a preferred solution, the polymer profiles 12 are
typically made of PVC.
[0068] In the structure 10, the device 1 is coupled to at least one wall 11. Typically,
as in Figs. 2A, 2B, 2D, and 2E, the device 1 is interposed between (and thus connected
to) two walls, which, for example, can be arranged parallel (as for example in the
embodiments of Figs. 2A, 2D, 2E) or angled to each other (as for example in the embodiment
of Figure 2B).
[0069] However, for example in the case of joints of several uprights and crossbeams in
the structure 10, as shown for example in Figure 2C, two devices 1 can each be coupled
to a wall 11 on one side and to the other device 1 on the other side.
[0070] Additionally, according to a possible solution, the devices 1 can be arranged at
uprights 10a and crossbeams 10b of the structure 10 so as to form one or more frames
within which the walls 11 are to be constrained.
[0071] The coupling between the device 1 and the respective wall 11 (or the respective walls
11) can take place in different ways.
[0072] For example, the device 1 and the wall 11 can be coupled by screws 13, such as in
the embodiment of Figure 2D.
[0073] Specifically, in a preferred aspect, the screws 13 are arranged within a respective
bushing which is inserted into the wall 11, typically into one of the polymer profiles
12 of the wall 11.
[0074] In addition or as an alternative, a device 1 can be arranged with interference between
two walls 11. For example the wall 11, in particular one of the respective polymer
profiles 12, can be provided with elastic fins 13 which, in use, are deformed by the
contact with the device 1, as shown for example in Figure 1A.
[0075] In addition or as an alternative, inserts or retainers 15 could be arranged between
the wall and the device 11 so as to be compressed by this arrangement.
[0076] Typically, such inserts or retainers 15 are placed at one of the metal sheets 11a
and facing the outer or inner (more typically outer) side of the structure.
[0077] In other words, the inserts or retainers 15 are arranged to increase the thickness
of the walls 11, that is to say the dimension arranged along the direction joining
the exterior and the interior of the structure 10.
[0078] It should be noted that the coupling between the device 1 and the wall 11 could be
not rigid. For example, a wall 11 could act as a door for the structure 10.
[0079] In such a case it is possible, for example, to constrain the device 1 and the wall
11 together by means of a hinge 14, so that the wall 11 can be rotated with respect
to the device 1. The wall 11 that acts as a door can be typically operated to be opened
or closed by at least one handle 19 or a corresponding operating device.
[0080] In use, a structure 10 has a framework comprising a plurality of uprights 10a and
crossbeams 10b. The walls 11 are constrained to uprights and crossbeams, so as to
form a closed structure.
[0081] The devices 1 are arranged next to at least part of the uprights 10a, typically next
to at least part of uprights 10a and crossbeams 10b. The devices 1 are arranged so
that the first profile 2 faces the outside of the structure 1, whereas the second
profile 3, covered by the polymer cover 8, faces the inside of the structure 10.
