[0001] The present invention relates to a modular sectional structure for various uses and
applications in general, having temporary or permanent character, particularly for
building boxes or stands and pavilions, etc., intended for fairs, exhibitions or the
like, or for creating indoor and outdoor open or closed areas, for example creation
of rooms or areas for various purposes as well as a solution for the subdivision or
separation of spaces or passages of rooms, or for example useable as a structure for
several applications and uses, such as for furniture pieces, furniture complements
or the like, for example tables, small tables for offices, expositors, shelvings,
etc.
[0002] The specific structures which have been up to now intended to partially perform these
functions cannot offer the advantage of practicality while at the same time meeting
aesthetic requirements and they not always provide a simple solution or are also comparatively
economically advantageous.
[0003] One of these structures according to the prior art is disclosed in US-A-3,797,948,
limitedly to a fastening means for tubular members, showing a channel-shaped member
attached at one end to a tubular member and formed with a longitudinally extending
slot. The channel's spaced apart walls, forced away by means of a spreading element
such as self-tapping screw, make frictional engagement with another tubular member's
inner walls, possibly provided also with a longitudinal slot.
[0004] The main object of the present invention is providing a sectional structure having
above all a multiplicity and versatility of uses and possibility of various utilizations
according to the desired solutions and needs of the user in various and different
activity fields or sectors, wherein assemblage of the constituting members can be
carried out easily and quickly so that very little skill is required in the interventions
for said assemblage, thus excluding or anyway reducing the need for specialized handwork
and also possible suitable auxiliary equipping.
[0005] Another object is providing a solution of greater manufacturing simplicity, which
nevertheless is statically suitable and reliable, and at the same time showing appraisable
aesthetic features.
[0006] A further object is allowing various composition possibilities with a limited typological
range of constituting members, by providing that some of these constituting members
have a large field of uses and adaptability even for the same construction, that is,
a single member being able to perform different functions, thus allowing various needs
and necessities of the user to be satisfied and also allowing possible subsequent
variations of arrangement and composition of said constituting members of the previous
construction, for instance because of the user changed needs, thus avoiding in this
case the difficulties of suitable changes or adaptation work.
[0007] A further object is allowing said constituting members to be quickly and repeatedly
disassembled in order to be assembled again, for instance, in another place with possibly
modified composition and arrangement in order to perform also a different function
with respect to the previous construction according to the user's needs, with possibility
of an easy transportation and moving by means of the usual transportation means.
[0008] These objects are obtained according to the invention by means of a modular sectional
structure, particularly suitable for the construction of furniture pieces, furniture
complements or the like, for instance tables, small tables for offices, shelvings,
expositors and the like or for creating open or closed areas, such as stands, boxes
for fairs, exhibitions and the like or for creating partition walls and the like,
that comprises vertical uprights, each of which is provided, in at least one position,
with at least one fitting at right angles therewith for the removable connection of
at least one horizontal transversal member, by which it can be connected to at least
one other vertical upright, characterized by comprising a connecting joint between
said fitting at right angles with an upright and a transversal member, said joint
comprising a first tubular joining portion integral with the upright and a second
tubular joining portion, coaxial with the first one and integral with the transversal
element, as well as an expansion pin partially insertable with the ends thereof into
said tubular portions and radially expandable by means of a screw for opening complementary
portions thereof and longitudinally matchable and screwed in accessible way in a median
collar of the expansion pin.
[0009] These and other features of the invention and the advantages deriving therefrom will
appear more clearly from the following detailed description of some preferred ones
among the advantageous and various embodiments of the invention, illustrated by way

[0010] With reference to the drawings, the structure according to the invention, suitable
for various uses and applications, comprises in modular coordination, members which
are statically suitable for performing upright function and provided with crosspieces
or lateral fittings intended to be associated and suitable for allowing union with
structural members for the connection of at least two uprights, so that according
to their position with respect to the upright and to their distance, various configurations
and geometrical combinations can be obtained, with wide composition possibilities
according to the desired solution, since said uprights and crosspieces are modularly
conformed so as to form altogether junctions having two, three or four ways, so as
to allow couplings with other structural members in different directions, by providing
for means for joining together and reciprocally fixing said different members, so
as to allow the assemblage of the whole structure with easy, simple and quick repetitive
operations, and being the so conformed structure suitable for allowing easy variations
and modifications of the composition and with the possibility of a likewise easy,
simple and quick disassemblage, re-assemblage and re-use of the components of said
structure.
[0011] The structure comprises uprights, provided in appropriate typological variability,
as a function of the position of lateral fittings 200 and their number, of the angular
arrangement in the same horizontal plane, preferably at 90° from each other or multiples
thereof, of the distance from the upper and lower end of the uprights, of the vertical
distance between them and all that with reference to the type of transversal member
to be associated and therefore with reference to the various employment necessities.
This concept and these variables give rise therefore to a number of embodiments, of
which some examples are illustrated in the sheets of the accompanying drawings.
[0012] Figs. 1, 2, 3 and corresponding figs. 1a, 2a, 3a illustrate a type of upright, respectively
101, 102 and 103, whose upper portion is provided with fittings or pairs of fittings
200, which are superposed and shortly spaced, arranged in a horizontal plane angularly
spaced from each other, particularly by 90°, in order to form junctions having two,
three and four ways respectively.
[0013] Uprights 104, 105, 106, 107 and 108 of figs. 21 to 25 and respective views of figs.
21a to 25a show pairs of fittings 200 at a relatively small distance from the upper
end, whereas the other fittings or lower pairs of fittings 200 are arranged at a certain
distance from the lower end, possibly vertically aligned or staggered if in several
superposed rows, in order to give rise to junctions having two, three ways and again
two, three and two ways respectively.
[0014] The types of uprights 109, 110, 111, 112 and 113 of figures 26 to 30 have lateral
fittings or fitting pairs 200 substantially near to the upper end, whereas the other
fittings or lower fitting pairs 200 are provided at a relatively short distance from
the lower end, possibly vertically aligned or staggered if in several superposed rows,
in order to respectively determine junctions having two, three ways and again two,
three and two ways respectively. Similarly, figs. 31 to 35 and respective figs. 31a
to 35a show other types of uprights 114, 115, 116, 117 and 118 wherein the lateral
fittings 200 are positioned in a various way in order to give rise to junctions having
two, three ways and again two, three and two ways respectively.
[0015] All the uprights are preferably tubular and into their lower ends are insertable,
according to the cases, a supporting foot 201 (fig. 1) or a preferably spinning and/or
brakable roller 202 (fig. 4).
[0016] To said uprights are associated, by means of fittings 200, transversal members having
different conformations, for instance straight, or curved, in particular arched, preferably
horizontally, provided in suitable dimensional range and typology, according to the
needs of use.
[0017] In fig. 5 the transversal member consists of a lattice crosspiece 301 longitudinally
provided with two parallel tubular bars 302, whereas in fig. 6 it consists of a plate-shaped
member 303 having holes and provided again with similar longitudinal bars 304, in
fig. 7 it consists of a curved lattice crosspiece 305 with relevant longitudinal bars
306, or it may consist in a crosspiece having the shape of a bar 307 (fig. 8) which
can have any profile in transversal cross-section, for example round or polygonal,
and is preferably tubular.
[0018] One type of transversal member can consist in a panel which can extend substantially
over the whole height of the upright or at least over the main part of the upright
height.
[0019] Some embodiments of said panel transversal member are shown in figs. 36 to 47 and
54 to 66.
[0020] Said panels can be provided continuous, such as for example panels 308 and 309, in
the version provided with holes, such as in panels 310 and 311, 320, 321, 322, 323,
324, 325, 326, 327, 328, 329, 330, which are straight, or also in the curved version,
such as in panels 312, 313, 314, 315, 316, 317, 318, 319, 331, 332. Said panels are
different from each other, for dimensional features and also for the typology of the
holes which can have any arrangement and pattern and size, and therefore also different
from the illustrated ones.
[0021] Each panel is strengthened by a perimetrical frame or is carried by the same, and
this frame can be provided on the side of the panel which is in sight (front side)
and/or on the opposite side (back side) of the panel itself.
[0022] Each frame of the panel comprises two bars 350 (fig. 36) rectilinear or arched according
to the above mentioned versions, preferably horizontal and parallel to each other,
provided on the same side of the panel and connected by means of two other bars 351
(fig. 36) preferably vertical and parallel to each other, provided on the same side
of horizontal bars 350 or on the opposite side of the panel. This is determined also
by the use needs and by aesthetic needs of the desired construction, being necessary
to provide in some cases fittings turned towards the internal side, such as with panels
312, 313, 314, 315, 331, or towards the external side in the other panels illustrated
as embodiments.
[0023] Said transversal members can be associated to the uprights by virtue of unbendable
connecting joints which can be used at lateral fittings 200.
[0024] In the embodiment shown in fig. 9, a type of connecting joint between a lateral fitting
of an upright and a transversal member comprises a first tubular joining portion,
integral with the upright, and a second tubular joining portion, which is coaxial
to the first portion and integral with the transversal member, for example bar 302
of member 301, as well as an expansion pin indicated as a whole with 340, partially
insertable with its ends into said tubular portions and radially expandable, by means
of a screw 341 for opening portions thereof 340' and 340" which are complementary
to each other and longitudinally matchable and screwed in accessible way in a median
collar of expansion pin 340.
[0025] According to one feature of the invention, constructions which can extend vertically
are allowed, since two or more uprights are insertable one in the other so as to form
a correspondingly longer upright, or extend longitudinally with transversal members
having possibly a different length and particularly panels having different vertical
and/or horizontal extension, or two or more superposed rows of uprights can be provided,
reciprocally connected by means of transversal members formed in particular of flat
or curved panels, in particular for forming walls having corresponding height, equippable
on one or both sides with accessories (not shown), with superposition of panels on
panels.
[0026] According to a feature of the invention said structure comprising the above described
components allows the assembly of constructions, such as furniture pieces, furniture
complements or the like, for example tables, small tables for offices, shelvings,
expositors, etc., or for creating open or closed areas, for example stands, boxes
for fairs, exhibitions, etc., or for creating partition walls, etc.
[0027] Some embodiments of said constructions are shown, for example, in figs. 11, 12, 13
and 14 such as tables, respectively 401, 402, 403 and 404, with relevant working surfaces
using the types of upright of figs. 1 and 2, whereas figs. 15, 16 and 17 show other
types of tables 405, 406, and 407 with relevant shelf accessories, 408, 409, 410,
411 respectively and again using the uprights substantially of the type of fig. 1.
[0028] Figs. 18, 19 and 20 show embodiments relevant to reception tables 412, 413, 414,
having curved conformation, comprising transversal members 305 (fig. 7) and 301 (fig.
5) and using uprights substantially of the type of figs. 1 and 2.
[0029] Figs. 48, 49 and 50 show further embodiments of structures according to the invention,
consisting in reception tables 415, 416 and 417 comprising uprights of the type of
figs. 21 to 30, with straight panels provided with holes of figures 38 and 39, crosspieces
of fig. 5.
[0030] Figs. 51, 52 and 53 show other embodiments consisting in curved reception tables
418, 419 and 420 comprising uprights of figs. 31 to 35, crosspieces 305, bars 307,
flat and curved panels provided with holes of figs. 38 to 47.
[0031] Figs. 67, 69, 70 and 71 show further embodiments consisting in creations such as
stands, whereas fig. 68 shows an exposing structure, all said embodiments comprising
panels of figs. 36 to 47 and figs. 54 to 66.
[0032] In said embodiments the above mentioned panels form curtain walls, partition walls
of rooms, subdivision of passages of rooms, etc., equippable on both sides so that
it is possible to apply accessories (not shown) such as shelves, brackets, etc., all
in modular coordination and in harmony with the preceding creations, such as tables,
small tables, etc.
[0033] It must be specified that the connecting joints between the lateral fittings and
transversal members can consist of male-female fittings.
