[0001] The present invention relates to a modular structure for the realisation of mouldings
along walls of buildings, of the type comprising the characteristics expressed in
the preamble of claim 1.
[0002] In particular, the modular structure according to the invention is suitable for the
realisation of mouldings serving as bumpers and/or handrails of the type commonly
installed for instance inside hospitals, schools, supermarkets and the like to protect
the walls against impacts and/or providing a bearing or gripping surface to facilitate
walking.
[0003] To this end, modular structures are currently employed which essentially comprise
a plurality of support bars, normally made of extruded aluminium, which are secured
to the walls in mutual alignment relationship, at a pre-set height from the floor.
[0004] On the support bars are engaged, by snap insertion, one or more covering elements
made of plastic material, destined to finish the visible surface of the moulding.
[0005] One or more gaskets interposed between the support bars and the covering elements
serve the purpose of damping the impacts whereto the moulding can be subjected, for
instance by persons or objects, such as carts, seats or others, which are made to
slide on the floor.
[0006] In correspondence with the extremities of the moulding, terminal elements are engaged
having each at least a plate-shaped insert suitable to be inserted into a respective
engagement seat defined in the cross section profile of the support bar and fastened
thereinto by means of threaded elements. Between different moulding portions delimited
in correspondence with the edges of the wall are also positioned junction elements
each fitted at the respective opposite ends with inserts engaging the support bar
in a manner similar to the one described above for the terminal elements.
[0007] Depending on whether the moulding is intended to serve exclusively as a bumper or
also as a handrail, the support bar presents a fastening side directly engageable
against the walls of the building, or it is structured in such a way as to be engaged
to the walls themselves by interposing suitable brackets able to maintain the fastening
side suitably distanced from the wall itself.
[0008] The Applicant has noted that the modular structures of the type described above can
be improved in several aspects, particularly in relation to constructive simplification
and to their ease of installation and mounting, as well as in relation to structural
strength and reliability over time.
[0009] In particular, it has been found that the quantity of different types of components
able to be associated in modular fashion to obtain the mouldings can be considerably
reduced.
[0010] It is also possible to improve the system whereby the different components are connected,
for the sake of greater strength and simplicity of installation.
[0011] Therefore, the subject of the present invention is a modular structure for the realisation
of wall mouldings in buildings, comprising the features expressed in the characterising
part of claim 1.
[0012] Further features and advantages of the invention shall be made more readily apparent
from the content of the detailed description that follows of preferred, but not exclusive,
embodiments of a modular structure for the realisation of mouldings along walls of
buildings, according to the present invention.

[0014] With reference to the aforementioned figures, the number 1 indicates in its entirety
a modular structure for the realisation of wall mouldings in buildings, according
to the present invention.
[0015] The modular structure comprises at least a support bar 2, for instance made of extruded
aluminium, suitable to be rigidly engaged to a wall of a building (not shown) by means
of its fastening side 2a oriented towards the wall itself. More in particular, normally
a plurality of support bars 2 is present, which bars can also be considered as segments
obtained by cutting the same section bar to measure and subsequently aligned to follow
the development of the walls of the building, at a pre-set height from the floor.
[0016] In the embodiment shown in Figure 1, where the modular structure realises a moulding
usable both as a handrail and as a bumper for the protection of the walls, each bar
2 is fastened to the respective wall by interposing spacers 3 set to maintain the
fastening side 2a of the bar itself at a pre-set distance from the wall. Each spacer
3 presents a plate shaped terminal portion 3a with rectangular profile, which engages
in a longitudinal seat 4 obtained on the fastening side 2a. This longitudinal seat
4 appears as a recess defined between two coplanar surfaces of the fastening side
2a. The width of the longitudinal seat substantially corresponds to the vertical dimension
of the terminal portion 3a of the spacer 3, thereby being suited to engage the latter
rigidly upon rotation. Each spacer 3 can then be placed in any position along the
support bar 2 but, as an effect of the engagement of its terminal portion 3a in the
longitudinal seat 4, it is advantageously inhibited from rotating with respect to
the bar itself.
[0017] A pair of threaded elements 5 extending through holes obtained in the bar and in
the spacer 3 and engaging in respective dowels 5a inserted in the wall ensures the
stable fastening of the bar 2.
[0018] The modular structure 1 further comprises terminal elements 6 each engageable to
a respective end of one of the support bars 2.
[0019] Each terminal element presents two opposite ends 6a, 6b oriented according to mutually
orthogonal directions. On a first end 6a is positioned at least a first connecting
insert 7a suitable to be inserted in a respective engagement seat 8 defined in the
cross section profile of the support bar 2. More in particular, at least two first
connecting inserts 7a are provided, oriented parallel and mutually distanced according
to a vertical direction, parallel to the fastening side 2a of the support bar 2. The
support bar 2 in turn presents two engagement seats 8, distanced according to a direction
parallel to the fastening side 2a to house the respective connecting inserts 7a.
[0020] Each of the engagement seats 8 is defined by an engagement portion 8a projecting
from the support bar 2, opposite with respect to the fastening side 2a and shaped
according to an arched profile.
[0021] As the accompanying figures clearly show, each connecting insert 7a presents substantially
cylindrical conformation, and is suitable to be engaged in the respective seat 8 by
means of axial insertion according to a direction parallel to the longitudinal development
of the support bar 2.
[0022] In correspondence with the second end 6b of each terminal element 6, internally hollow,
an auxiliary seat 9a is defined for the snap engagement of a substantially plate shaped
closure portion 9. Said closure portion 9 can present a substantially planar external
surface 9b, positioned flush with the second end 6b, to prevent the entry and accumulation
of dirt and/or detritus in the terminal element 6. Alternatively, to the closure portion
9 is associated at least a second connecting insert, and more specifically two connecting
inserts 7b, projecting from the external surface 9b.
[0023] The second connecting inserts 7b are shaped similarly to the first inserts 7a, and
each is positioned coplanar according to a perpendicular orientation with respect
to one of the first inserts themselves. The second inserts 7b thus are suitable to
engage in the engagement seat 8 provided in the bar 2, in a manner similar to that
described for the first connecting inserts 7a.
[0024] In the presence of the second connecting inserts 7b, the terminal element 6 constitutes
an angular junction indicated in its entirety with the number 10, connecting two contiguous
support bars 2 angularly positioned to follow the development of the walls in correspondence
with an angle. Advantageously, the engagement seats 8, as well as the connecting inserts
7a and 7b, are shaped and positioned symmetrically with respect to a first and a second
mutually orthogonal axes of symmetry respectively indicated as X and Y in Figure 2,
observable on the cross section profile of the terminal element 6 engaged to the support
bar 2, as shown in Figure 2. Thanks to this feature, each terminal element 6 is suitable
to be indifferently engaged to one or to the other end of a support bar 2, according
to orientations offset 180° around the horizontal axis X, orienting the first inserts
6a towards the engagement seats 8 respectively in correspondence with one or the other
end of the bar 2.
[0025] The symmetry with respect to the vertical axis Y also allows to engage the angular
junction element 10 according to two different orientations mutually offset 180° around
the vertical axis itself, to be selected respectively according to whether the junction
element is to be positioned in corresponding with a convex angle (Figure 1, 5 and
6) or with a concave angle (Figure 4) formed by contiguous walls.
[0026] Advantageously, the engagement of the first and/or second inserts 7a, 7b in the respective
seats 8 occurs by means of a simple inserting action with axial sliding in a direction
parallel to the longitudinal development of the support bar 2, preferably until the
end of the terminal element 6 bears against the corresponding end of the bar itself.
Once the insertion operation is complete, each of the first and/or second connecting
inserts 7a, 7b is suitable to be axially locked in the engagement seat 8 by means
of at least a locking pin 11 which can be inserted through holes obtained, for instance
upon installation, through the bar 2 and through the connecting insert 7a, 7b itself.
[0027] To connect two support bars 2 positioned in mutual alignment, the modular structure
1 provides for the use of connecting inserts 12 shaped similarly to the connecting
inserts 7a, 7b and able to be inserted in the engagement seats 8 of the respective
bars to assure the perfect alignment thereof in correspondence with their ends joined
head-to-head. In this case as well, securing pins 11 can be inserted through respective
through holes obtained in the bars 2 and in the connecting inserts 12 to assure the
axial locking thereof in the respective engagement seats 8.
[0028] To each of the support bars 2 can moreover be associated at least a covering element
13, preferably made of extruded plastic material, set to cover the bar itself on the
side opposite the fastening side 2a.
[0029] In the embodiment shown in Figure 1, each covering element 13 presents substantially
C shaped section, with two terminal appendices 13a forming an undercut and set to
be engaged by snapping, passing over the opposite longitudinal borders of the bar
itself in correspondence with the fastening side 2a. To ease the snap engagement of
the covering element 13, the bar 2 presents, along the opposite longitudinal borders,
two guiding appendices 14 converging towards a horizontal plane containing the horizontal
axis of symmetry X, thereby defining inclined sliding planes 14a that facilitate the
spreading of the terminal appendices 13a when the covering element 13 is engaged to
the bar 2 with a thrusting action directed towards the bar itself.
[0030] At least a bumper lining 15 engaged in a corresponding groove 16 provided in the
bar 2, opposite to the fastening side 2a, is suitable to act internally against the
covering element 13 to dampen impacts whereto the latter, and therewith the entire
moulding formed by the modular structure 1, can be subjected.
[0031] The longitudinal groove 16 for the insertion of the bumper lining 15 is advantageously
provided on a longitudinal bearing portion 17 projecting from the opposite side with
respect to the fastening side 2a, for the purposes that will become more readily apparent
farther on.
[0032] The embodiment shown in Figure 4 differs from the description above in that the spacers
3 are replaced by plate shaped bearing elements 18, suitable to be positioned along
the longitudinal seat 4 and able to be fastened, by means of insertion thereinto,
in rotational direction with the respect to the bar 2. In this embodiment, each of
the support bars 2 is applied with its fastening side 2a directly against the walls
of the building, possibly after interposing plugging gaskets 19 engageable in respective
sealing grooves 19a provided on the fastening side 2a of the bar 2.
[0033] Otherwise, the embodiment of Figure 4 is substantially identical to the description
given with reference to Figures 1 through 3.
[0034] In the embodiment of Figure 5, the support bars 2 are in the form of sections of
very limited length mutually distanced along the respective walls. With respect to
the embodiment described above, both the spacers 3 and the bearing plates 18 and plugging
gaskets are lacking. Also absent are the connecting inserts 12 described with reference
to the embodiment as per Figures 1 through 3. In this case, the mutual alignment between
the different support bars 2 is assured by at least an auxiliary bar 20 able to be
engaged by snapping on the bearing surfaces 17 belonging to different support bars
2 mutually aligned, preferably to replace the bumper lining 15.
[0035] More specifically, the engagement of the bar 20 on the bearing surfaces 17 occurs
by snap coupling of first teeth provided along opposite terminal edges 20a of the
auxiliary bar itself, engaging with second coupling teeth 17a (Figure 2) provided
on the bearing portion 17.
[0036] The auxiliary bar 20 preferably presents, on a side oriented towards the covering
element or elements 13, an auxiliary longitudinal seat 21a, suitable to house an auxiliary
bumper lining 21 that serves the same functions described with reference to the bumper
lining 15 as per the embodiment illustrated in Figures 1 through 4.
[0037] In the embodiment illustrated in Figures 6 and 7, each of the engagement seats 8
is defined by a tubular portion 8b with circular profile positioned along a longitudinal
edge of the support bar 2.
[0038] The tubular portions 8b are mutually distanced according to such a measure as to
define between them the longitudinal seat 4 for the engagement of the terminal portion
3a of each spacer 3.
[0039] As Figure 6 clearly shows, the terminal elements 6 and/or junction elements 10 present
a curvilinear plan profile, with curvature radius correlated to the size of the spacers
3 and substantially equal to the distance of the median vertical axis Y from the wall
against which the support bar 2 is fastened.
[0040] Each covering element 13 is counter shaped to the cross section of the support bar
2, with the respective terminal portions 13a shaped according to an arched profile.
[0041] The present invention attains important advantages.
[0042] The doubly symmetrical disposition of the engagement seats 8, along with the constructive
solutions adopted in the realisation of the terminal elements, allow considerably
to reduce, with respect to the state of the art, the number of component types necessary
to realise moulding which may even differ from each other. In other words, the modular
structure according to the invention allows to realise different types of mouldings
assembling according to different configurations a limited number of components of
the same type, that is to say obtainable from the same mould or from the same extrusion
die plate.
[0043] In this regard, it should also be noted that all the embodiments as per Figures 1
through 5 are obtainable by means of the same base bar 2, covering element 13, terminal
elements 6 and/or junction elements 10, as well as connecting inserts 12.
[0044] It should further be noted that the distanced positioning along the vertical axis
Y of the engagement seats 8 and of the connecting inserts 7a, 7b, as well as their
mutual engagement obtained by means of axial insertion in the direction of longitudinal
development of the bar 2, allows to obtain an excellent structural resistance in the
connection between each terminal and/or junction element and the bars themselves.
In particular, the junction and/or terminal elements can also be exploited, if need
be, to serve functions sustaining the support bars, for instance if, as may occur
in correspondence with edges formed by pillars projecting from the wall, the reduced
longitudinal development of the bar 2 and/or its positioning do not allow it to be
fastened directly on the wall.
[0045] The invention further attains considerable improvements in terms of simplicity in
setting up and installing the mouldings. In particular, each support and respective
covering element, supplied in pre-assembled condition to the installer, can be cut
to measure simultaneously. The structure of the terminal and/or junction elements
allows to maintain the same length for each support bar and the respective covering
element, circumstance which is not provided by prior art devices which require additional
cutting operations on the support bar, which must necessary present a slightly smaller
longitudinal development.
[0046] Also the assembly of the terminal and/or elements to the support bars, which can
be performed by means of simple axial insertion operations without requiring the use
of any threaded element, is considerably simplified with respect to the prior art.
