[0001] The present invention relates to a panel, having accordingly a thickness of approximately
18 mm or more, that is particularly usable in the field of kitchen furniture, such
as for example kitchen worktops, table tops, exposed doors and side walls of furniture
carcasses, commonly known as finishing sides.
[0002] Table tops and doors made for example entirely of plastic material or wood coated
with waterproofing paint are currently commonly used in the field of kitchen furniture.
[0003] It is also known to use panels formed by a flat body made of plywood or chipwood,
fully covered with a lamina made of plastic material or by a veneer of wood, glued
appropriately onto the respective faces of the flat body.
[0004] It is also known to apply a border to a panel, made for example of plastics, by thermal
bonding of a strip of plastic material that is covered externally with a metallic
lamination.
[0005] All the known types of panel cited above have various drawbacks, due mainly to the
fact that the materials used often do not have aesthetic or technical characteristics
that are adequate for their use.
[0006] In particular, the panels made of wood and/or plastics described above are prone
to damage, which can occur due to exposure to high temperatures, to accidental impact
with foreign objects, or due to water infiltrations.
[0007] Kitchen furniture in fact necessarily has to be arranged proximate to heat sources,
such as burners, the electric or gas-fired oven, and any other heating devices, and
often also acts as containers or stands for said heating devices.
[0008] Likewise, kitchen furniture accommodates or is usually arranged adjacent to at least
one sink or even a dishwasher, and can also act as supporting bases for pots or kitchen
vessels and accordingly are often in contact with water or other liquids.
[0009] The main drawback of these known kinds of panel is that they often have a limited
durability, or in any case are subject to wear and to a gradual damage or deformation
that can also entail separation of the respective borders constituted for example
by said strips of plastic material or lamina.
[0010] The panels that are most intensely affected by this wear are in fact the ones that
lie closest to source of heat or water, since depending on the type of panel used
there may be a first initial slight peeling of the plastic lamina, which usually occurs
at the connecting region between the border and the surface, and especially at the
corners of the panel; or a small portion of paint might be removed, leading to loss
of the waterproofness characteristic.
[0011] While maintaining their functionality sometimes unchanged, these known types of panel,
once damaged, have the drawback of having in any case a substantially compromised
aesthetic impact which is in any case unpleasant.
[0012] This leads to the severe drawback of not only compromising the overall pleasantness
of the kitchen but also of causing in the user the perception of low quality of the
kitchen.
[0013] In the field of office furniture it is also known to use doors made of wood or plastics
that have, on one or more sides, covering borders made for example of rubber which
affect the entire height of the edge.
[0014] This known type of door, however, is difficult to use in the field of kitchen furniture,
since the mechanical and thermal stresses described above, which are frequent in using
said kitchen, can easily entail damage to the rubber borders.
[0015] The described drawbacks are worsened if a wood panel of great thickness, measuring
therefore 18 mm or more, is used, since very powerful forces become involved and are
discharged onto the border, deforming it or breaking it.
[0016] As a partial remedy to the drawbacks noted above it is known to provide panels constituted
by a frame, made of metallic material such as aluminum, which has a square or rectangular
shape.
[0017] Such frame is optionally provided with one or more horizontal crossmembers that are
suitable to divide the delimited internal region into two or more rectangular or square
areas, which can be conveniently closed by positioning and fixing complementarily
shaped flat bodies made for example of wood or plastics.
[0018] This solution, too, has the drawbacks noted above and therefore entails the possibility
that due to heat and/or humidity the panel undergoes deformation, entailing deformation
of the frame; moreover, in this solution the manufacture of the components and most
of all their assembly are very onerous from the economical point of view, since they
require the use of expensive materials and the use of labor for a considerable period
of time.
[0019] The manufacturing cost of the frame, moreover, is particularly onerous since it must
have a transverse cross-section and a thickness that ensure rigidity and support to
the entire panel.
[0020] The aim of the present invention is to solve the above-noted problems, eliminating
the drawbacks of the cited known art, by providing an invention that allows to obtain
a very thick panel, particularly for kitchen furniture, in which the perimetric structure
is stable over time, said panel being cheap to manufacture and assemble and at the
same time maintaining its aesthetic and functional appearance.
[0021] Within this aim, an object of the invention is to provide a panel that can be assembled
even automatically by using appropriately provided machines, further reducing manufacturing
costs and potentially increasing production.
[0022] Another object is to provide a panel that allows to contain any deformations due
to infiltrations of water or heat.
[0023] Another object is to obtain a large panel that has optimum mechanical strength, particularly
at the regions that are stressed most intensely, therefore at the edges and comers.
[0024] Another object is to provide a panel that is structurally simple and has a particularly
pleasant, innovative and durable aesthetic impact.
[0025] This aim and these and other objects that will become better apparent hereinafter
are achieved by a high-thickness panel, particularly for kitchen furniture, characterized
in that it is constituted by a flat body, along the perimeter of which it is possible
to associate separate metallic profiled elements that have means for mutual angular
connection.
[0026] Further characteristics and advantages of the invention will become better apparent
from the following detailed description of a particular embodiment thereof, illustrated
by way of non-limiting example in the accompanying drawings, wherein:
Figure 1 is a perspective view of the panel according to the invention;
Figure 2 is a sectional view of the panel, taken along the line II-II of Figure 1;

body;

Figure 7 is a sectional view of the panel, taken along the line VII-VII of Figure

[0027] With reference to the figures, the reference numeral 1 generally designates a large
panel, which as such has a thickness of approximately 18 mm or more and can be used
to manufacture furniture and particularly for kitchen furniture and components for
kitchen furniture, such as for example worktops, table tops, exposed doors and/or
sides of carcasses of furniture, i.e., finishing sides.
[0028] The panel 1 is constituted by a flat polygonal body 2, for example square or rectangular,
at lateral edges 3 of which it is possible to associate respective metallic profiled
elements, designated by the reference numeral 4.
[0029] A first seat 6 is in fact provided at each of the lateral edges 3 at right angles
thereto and proximate to an upper surface 5 of the flat body 2, and affects the depth
of the flat body 2 for a few millimeters.
[0030] A recess having a chosen depth, designated by the reference letter A in Figure 4,
is further provided at each lateral edge 3 in a portion 7 that lies between a lower
surface 8 of the flat body 2 and the first seat 6.
[0031] The metallic profiled elements 4 are associable with the flat body 2 at the lateral
edges 3, are internally hollow and have, in a transverse cross-section, advantageously
a rectangular plan shape, with a lateral tab 10 that is shaped approximately complementarily
to the first seat 6 at an upper face 9.
[0032] The height of each metallic profiled element 4 is such that once the lateral tab
10 has been arranged in the first seat 6 a lower base 11 is arranged approximately
flush with the adjacent lower surface 8 of the flat body 2.
[0033] The various metallic profiled elements have a length equal to the corresponding lateral
edge with which they are to be associated; the ends 12 of each metallic profiled element
being cut at a chosen angle in order to allow connection to the adjacent metallic
profiled element.
[0034] In the particular embodiment shown, when using a flat body that has a rectangular
or square shape, the ends of each metallic profiled element are advantageously cut
at 45°.
[0035] The panel uses means for mutual angular connection between two adjacent metallic
profiled elements.
[0036] Such means are constituted by a comer element 13, which has in plan view a configuration
that in the particular embodiment is substantially L-shaped and can change according
to the perimetric configuration of the flat body 2.
[0037] Each corner element 13 has, in a transverse cross-section, a shape that is approximately
complementary to the cavity 14 formed at each metallic profiled element, since it
is hollow.
[0038] Therefore, the coupling of each metallic profiled element to the lateral edge 3 of
the flat body 2 provides for the positioning of a first metallic profiled element
so that the lateral tab 10 is arranged in the first seat 6 and then the insertion
of a wing 15 of the comer element 13 in such metallic profiled element followed by
the subsequent positioning of an additional metallic profiled element at the adjacent
lateral edge of the flat body and its sliding or positioning at the other wing of
the comer element 13.
[0039] To allow stable interconnection between two adjacent metallic profiled elements,
at the lower face 11 of each profiled element and proximate to the end 12 thereof
there is a second threaded seat 16 that interacts with suitable screws 17, the stem
18 of which can be accommodated at a suitable slot 19 formed at the adjacent overlying
wing 15 of the corner element 13 previously inserted in the cavity 14 of the metallic
profiled element 4.
[0040] As an alternative, instead of the slot 19 it is possible to provide a third seat
that is shaped complementarily to the stem 18 of the screw 17.
[0041] The positioning of the screws allows to achieve stable locking of the various metallic
profiled elements, which therefore form a practically non-deformable rigid frame perimetrically
with respect to the flat body 2.
[0042] It has thus been found that the invention has achieved the intended aim and objects,
a high-thickness panel having been provided that can be used to manufacture furniture
and particularly kitchen furniture and whose perimetric structure is stable over time,
such solution being further economical to manufacture and assemble and at the same
time maintaining over time its aesthetic and functional appearance.
[0043] This solution can be assembled even automatically, by using suitable machines, with
a further reduction of manufacturing costs and a potential increase in production;
moreover, it allows to contain any deformations due to infiltrations of water or heat,
by virtue of excellent mechanical strength, particularly at the regions that are stressed
most intensely, such as the corners.
[0044] 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.
[0045] 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.
