[0001] The present invention relates to the field of components for the furniture manufacturing
and specifically to a modular system to make shutters.
[0002] Making furniture shutters, such as wall units and bases for a modular kitchen or
wardrobes, typically includes plain or drummed thickness panels, finished with veneering
and varnishing; these panels must be every time prepared in the wished dimensions
or prearranged and stocked according to the same dimensions.
[0003] A first inconvenience is the unavoidable limit in the size tipologies and the narrow
modularity only achievable from the combination of standard elements.
[0004] Such panels, usually made of heartwood or substitutes such as shavings, fillets,
plywood have got all the inner drawbacks of the base material - wood - such as: high
degree of hygroscopicity, high deformability, bent for the longitudinal warping at
the maximum heights, lacking borders endurance with consequent deformation and alteration
of the finish layers; all that causing thereto an unexpected obsolescence and endurance
unreliability in the shutters approaching and in the connection with hinges.
[0005] An other problem concerning the use and experimentally proved is caused by the glues
containing toxicants used to make the panels based on shavings agglomerates or sawdust,
which release with the time particularly dangerous substances if considering the long
period of contact with the users, as in household furniture.
[0006] A further inconvenience is that the use of wood and substitutes has proved not to
be in line with a tolerable development, with consequent deforesting problems.
[0007] It is the main purpose of the present invention to prevent the aforesaid disadvantages
and, within such a task, a first aim of the invention is to carry out a modular system
to make furniture shutters without any restriction in the shutters' size tipologies
and with the possibility of an unlimited modularity.
[0008] A further aim of this invention is to obtain shutters modularity attained by this
system, both horizontally and vertically.
[0009] An other feature of the present invention is to provide a system able to make the
furniture shutters indeformable even under unfavorable environment conditions, as
in presence of heat, damp, steam, etc., and to make them unchangeable even on the
external finish layers.
[0010] An other feature is to provide shutters whose borders are proved to be reliable with
the time, so as the endurance for coplanar shutters approaching and the endurance
of shutters linked to hinges.
[0011] A further feature is to provide a system to make furniture shutters based on materials
and components without toxicals, completely recyclable, not based on sparely or almost
unavailable vegetal materials and with a following impoverishment of the environment
estate.
[0012] The last but not less important feature is to provide a system to make modular shutters
which, although it is carried out with high industrial technologies, don't require,
for installation and final equipment, any complex technology or particularly skilled
Labor.
[0013] These and further features are achieved in a modular system to make furniture shutters
including a single modular section bar, with varying length and width depending on
the shutters' size to obtain and their use, said section bar showing lengthwise means
which allow the link "n" times to "n" section bars having the same shape, said link
made possible by a continuous seal, said means being able at the same time to hold
flanging means and/or connection means of a translucid element to make a glass-fronted
area on the shutter, said shutter formed by "n" section bars rimmed by cross continuous
means, said shutter resulting from such section bars having finished the upper and
the back surfaces and consequent to the finishes these section bars are provided with.
[0014] Further features and advantages of the invention will be better shown by the description

[0015] Referring to the figures from 1 to 4, it is illustrated the modular element 1, basing
the system, with two tipologies of profiles; said modular element consists of an extruded
aluminum section bar, whose length equals a furniture shutter and width equals its
submultiples and consists of two hollow closed chambers 2 and 4 in rectangular section,
adjacent and with a same volume, provided at the two opposite ends 5 and 15 with two
continuous round grooves 12 and 22 that have respectively two first 14 and 24 and
two second 16 and 26 continuous projections; said second angularly situated projections
16 and 26 limit respectly two first walls 17 and 27 of two ducts 18 and 28 whose second
walls 19 and 29 are also limited by the heads 20 and 30 of the dorsal wall 40 of the
section bar 1; said continuous wall connecting the hollow chambers 2 and 4 is externally
provided with a finished grained surface 56. The frontal 50 connecting the hollow
chambers 2 and 4 is a solid wall that can be overlaid with a finishing material such
as PVC or wood, or varnished, and it sets the sight wall of the relative shutter.
The two hollow chambers are divided by a partition wall 45 provided with a C-shaped
inward profile.
[0016] The two ends 5 and 15 of the section bar 1, equal and specular in the construction,
are fit for holding different kind of profiles according to the wanted function; the
profile 3 illustrated in the figures 1 and 2, is used on the base section bar 1, when
the end on which it is applied has to work as finished longitudinal border. Said profile
is provided with a continuous bead 13 able to be shrunk in the groove 12, said bead
being jointed with the vertically wall 23, having the external face 43 provided with
a grained surface and the internal face smooth; opposite the bead 13 there is a wing
"L" profile 33, able to be shrunk in the conduct 18 of section bar 1.
[0017] The profile 6, illustrated in the figures 1, 4, 5 and 6 is used between two or more
section bars 1, 1a, 1b, 1c as coplanar joint. It is provided with two opposite continuous
beads 32 and 34 which will shrink respectively in the two relative grooves 22 and
12a, whose the groove 22 is situated at the right end of a section bar 1 and the groove
12a at the left end of the adjacent section bar 1a; opposite to the beads 32 and 34,
at the ends of the grained face 57, there are two specular wing profiles with a L-shaped
terminal 35 and 37, whose profile 35 is fit for being shrunk in the conduct 28 of
head of profile 1 and the profile 37 can be shrunk in the conduct 18 of the profile
1a. In the figure 6, where the use of three section bars 1, 1b, 1c is showed, two
similar joints 6 and 6a are used, shrunk respectively both in the grooves 22 and 12b
of section bars 1 and 1b and in the grooves 22b and 12c of section bars 1b and 1c,
and in the back ducts 28 and 18b of section bars 1 and 1b and 28b and 18c of section
bars 1b and 1c.
[0018] A further border profile 9, as illustrated in the figure 9, is used in the box furniture
shutters in need of dust-cover gaskets; it consists of a border head 39 provided with
a continuous back wing extension 38, said extension as male function to hold the dust-cover
gasket not represented in the figure; the structure of profile 9, as far as the anchorage
to the section bar 1 is concerned, is based as before on bead 13, shrunk on the groove
12 and on the wing "L" profile 33, shrunk in the duct 18.
[0019] Referring to the figure 7, the same section bar 1 and 1a with the same heads construction,
can be used to make a glazed shutter using a special continuous profile illustrated
by the numbers 7 and 7a, provided axially with a duct 11 and 11a to fix the glass
10; opposite to such duct the continuous profile has the above mentioned structure
and includes a continuous bead 8 able to shrink in the groove 22 of the section bar's
1 end and a wing profile provided with "L" end 54, shrunk in the duct 28 of the same
end; said profile will be used at the opposite end of section bar 1a. The glass holder
profile is provided with a grained finishing back shoulder 25.
[0020] In the figure 8 is shown a section bar to carry out the shutter's off-module measures;
this is attained through a longitudinal cut of one of the two hollow chambers with
the consequent removal of head shaped to hold the ending profiles, on said cut the
release insertion occurs of a special aluminum profile having a grained plane finishing
head 55 and two wing ledges 31 and 41, the first of which plane 31 gets in the hollow
chamber 4 in contact with the frontal wall 50 and the second one arcuate 41 situated
against the rear wall 40, the whole carrying out a finishing stopper.
[0021] The height variability of the single shutters formed by the aforesaid section bars
is attained by a transversal cut; in said cut is introduced, by a horizontal milling,
a special aluminum profile 44, essentially having "U" section, which, clamped by self-tapping
screws, makes the single sectors each other integral; on the profile 44 is shrunk
by pressure an aluminum cover thread 46 having a finishing grained border 47 and two
continuous internal wing elements 48 and 49 whose heads are respectively provided
with a shoulder 51 and 52.
[0022] The advantages of this system to make modular shutters for furniture are evident,
especially considering that modularity and formal shapes in their size variables are
attained by using a single modular section bar.
