BACKGROUND o~ the INVENTION.
The invention relates to a s~ri~s of elements to
be used in the construction of ventilated facades.
V~ntilated fac3des ar~ wall-coverings made wïth
ceramic t;les or other materials (marble, granite~
05 and kept out of contact, by m~ans of a frame, w;th
the wall they are destïned to cover, so a5 to
create a ventilated channel between the wall and
the facade.
The vent;lated channel functions as a heat-
;nsulat;ng chsnnel and allows better transp;ration
of the wall to be covered. The prior art in the
field of vent;lated facades teaches the
application o~ the tiles on special metallic
frames w;thout the use of cemsnts, having rather
complex hooking sV~tems, and of~erlng only a
limit~d possib;lity o~ regulating either the tile~
or the frame during the mount;ng op~ra-t;on.
An aim of the present ïnvention is thus that of
elim;nating the above-mentionecl clrawbacks and
realising a ventilated facade in 3 very simple and
economical way, with a support fralne for the
tiles, which ~rame position c3n be reg(Jlated
during the mounting operation, and with tiles
.
,

'. ' .
shaped ;n such a way as to b~ applicab1~ by s;mple
fitting on the frame.
A` f~rther eirt7 o~ the ;nvention ;s that of
obviating wr~ong mounting, for examp'l~ fitting
05 tiles ups;de down. This ;s palticu'lanly us~u'l
when dea1ing with square ti'les havîng sp~cial
deslgns on the s;de in view.
SUMMARY of the _NVENTION.
The s&7id aims are ~ully sat;sfiecl by the series of
elements, object of the present invention, fon
re~71is;ng a vent;1ated facad~, characteris~d ;n
that it comprises:
- horizonta1 cross-b3r~s equïppçd with a slot on at
least one side ~or the ;nsertion of fixing means
of sa;d cross-bars;
1s - t;les which can be inserted by a simpl~ fitting
between two crc)ss-b~rs, s~id ti1es being equipp~ct
with peripherA1 groovas hidcden ~nom view al7d cut
into the breadth of the maerial constituting the
tile,, to enable its application bV simple fitting
between the cnoss-b~7rs in s-lch a wa~ that 3 sh~7ped
profi1e of the sa;d cro$s-bars inserts into the
; corresporlding grooves in the t;1es.
.. ':,.
'- ' '
,
The series may also comprise vertîc~l uprights
provided with slots on at least three sides,
whereon the said crossbars ~re ~nchored, ~5 well
as U-bolts for anchor;ng the vert;c31 upr;~ht 3 to
05 a wal1.
An object of the present invention is also to
provide a tile for re~lising ventilated f~c~des,
~pplic~ble to a metallic frame const;tuted by the
~eries of elements as ~bove-descr;bed, or to
another met311ic fr3me, for example of tha type
for walls which to be erectsd between a floor and
a ceiling, the sa;d ti1s belng equ;pped, ;n the
part of ;t h;ddan from view, w;th grooves and
bevellin~s such tha~ the posterior surface of the
tile is hidden below and the anterior surface of
the tile i~ in v;ew.

DESCRIPTION of the PREEERRED EMBODIMENTS.
With refer0nce to ths drawings, 1 denotes
metallic vertical upright, const;tut;ng the thind
e1ement of a series, which upright 1 ha5 a
; - transversal section which is subst~ntially sll~ped
in a "U" and which ;s equippped with a tripl~

s3i ~
~er;e~ of slots. Th~re is 3 p1ur~1ity of front~'l
slots'6 and lateral ~lots 7, the latter being mada
or two opposite sides of th0 upright 1 and having
a superlor interaxis with respect to the ~xi~ of
05 the frontal slots 6.
A plurality of uprights 1 are fixed to a w311 15
to be covered by a venti'latecl fac3de, by means of
U-bolts 2 constitut;ng the fourth element of the
ser;es.
lo Tha U-bolts 2, as ;tlustr~ted in f;gures 1 and 2,
3re equ;pped with two through~ho'les 10 for
3nchoring to the wall 15 w;th screws 5, ancl are
further equ;pped w;t,h ~ couple of opposite ~tateral
threaded holes 9 in wh;ch convention~l fixing
means 1~ (for example9 bolts~ are in~erted to
anchor the U-bolts 2 to the uprights 1.
The anchoring of the upr;~hts 1 c3n be effected
during the placing of the uprights 1 themselve~
since the fixing means 13, insert;ng into the
13ter~1 slots 7 of the uprights 1 can thus permlt
of small movamen's in the;r pos;t;onin~, whîch ;5
espec;~lly useful ;n ca5es whera the w311 1 5; 5
not perfectly fl3t but exhib;ts ;rr~gul 31'`'i ti a5
that manifest themse'lves in an imperfect a'lignment
2S of the U-bo'tts 2 previously fi'xed 'loosely on the

uprights 1.
In an alternative ambodim~nt of th~ inventior),
illustrated in figure 10, the vertical uprights 1
can ha~e a "C"~shaped tr~nsver~al section ~nd can
05 be internally aquipped with mi11ing 29 to cne3te
friction against ~F;x;ng plates 28 ;nserted in the
uprights 1.
The uprights l c~n be providacl with a plurality of
lateral slots 27.
With reference to f;gure 4, a hori~ont~'l crossbar
3 constitutas the ~irst element of the ser;es and
exhibits a profile which is subst3ntially equal to
that of the vertical upri~hts 1, but which ïs also
equipped with two tabs or appendices 14~
perpendicular with r~spect to the vertical sides
of the "U", which when mounted are arranged
parallel to the wa'll 15 as shown in f;gure l.
The tabs 14 are asymmetrical, that is, th~re are 3
smal1er-width tab 14a and a wider-w;dth tab l4b.
Each crossbar 3 is equ;pped on a central s;d~ w;th
3 plwrality of slots 8 ;n wh;ch f;xing m ans 16
are ;nserted, wh;ch fix;ng msans 16 can be very
sim;lar to the said fixing me3ns 13, to anchor the
crossbars 3 to the vertical upr-îghts l, in th~
manner~ shown in figure l. The fixing mean~ 16 are
;nserted 9nto the s'lots 8 of the crossb3rs 3 and
into th~ frontal slots 6 of the uprights l.
The crossbars 3 can b~ equîpped w;th a plur31-ity
o~ apertures 19 to permit the dra;ning o~ 3ny
05 eventu31 accumu1at10ns of n3i nwater ~
The interaxis of the s1ots 8 in the crossbars 3 is
1ess than the long;tucl;nal d;mens;on of the
correspond;ng front31 slots 6 and th~ longit-lcl;n31
d;mension of the s10ts 8 of the crossbars 3 is
1arger th~n the interaxis of the frontal s10ts 6
o~ the uprights 1 so that a possible couplil1g
betwecn crossbars 3 and uprights 1 in any of the;r
re1ative positions c.an always be gu~ranteed.
In ~ further emobdimel1t, i1'lustr3ted in figures 7,
8 and 9, the crossbars 3 can have a substarltia11y
~'L"-shaped transversa1 sect;on with a short 'leg
termin~ting in the tabs 14.
The fixing means 16 c~n be usecl to fix the
crossbar~ 3 to the upr;ghts 1 of figur~e 10, using
the f;xing p1ates 2~.
The h;ghest 3nd 'lowest cro~sbars 3 will b~
equipped on1y with the tab l4a, .~s shown in figure
8.
With r~eference to fiyures 5 ancl 6, 4 cl~notes

series, which can be made of ceramic ma-t~ri~l,
m3rble, yranite or other materi~ls besides, and
can be of v3r;0us shapas.
Each tile 4 ;s equ;pped ~.~;th two groov s 1l,
05 p3rallel to each other and hidclen from view,
ch3nnelled p~ripher~'lly into the bre~dtll of the
materi~l constituting th2 tile, on two oppos;te
s;des of the t;le ;tsel~. The s3id two groovas 11
are asymmetr;cal s;nce the tabs 14a and 14b of the
crossb~r~s 3 insert in-to them by simple fittin~.
As is shown in ~igures l 3nd 6, the two grooves ll
are shaped so that the poster;or surface of the
tile ;5 lower than'its Front surf~ce, which latter
i5 in view; in other words, in a vertica'l section
the tile exhibits two asymmetricsl edges of tlle
two tila yrooves 11. A front ed~e 17 neaclles up to
the peripher~l edge of the tile, while g poster;or
ed~e 18 of the ~roove is substantially 'lowered to
p~rmi~ of perfect coupling of the tlles when
mounted, as shown ;n f1~ure 1.
The series of e1ements which is obj~ct of tl~e
present invent;on is constituted by the crossbars
~ and the tiles Ll, to which can be sdded~
preferably but not necessar7'ly, ~ third and a
fourth element constituted by the upr~igh-t~ l al-d

the U-bolts 2, or by the upI~igIts 1 ~nd th_ fixing
plates 28. Ventilated facacIas c~n ba ra~IIised by
using 311 four of the above elamsnts, as
;11~stratecl ;n f;~ure II or they can be made
05 s;mply with the crossbars 3 ~nd the pl3te 1" w;th
the cros~bars 3 anchor~cl for exampla to me~allic
frames of known typa, for extarnal wa11s or
arect;ons between floor 3nd ceil;ng.
The realis3tion oF a venti1at~d facacIe with the
lo complete series oF elem~nt~ of the invention
anvisages the fo110win~ ph~ses:
- a prelimin~ry and loose anchoriI-g o~ th~ U-bo1ts
2 internally to tha upr;ghts 1 to en~ble
subsequent regulat;on of the pos;t;on oF tha
uprights 1;
- f;xing the U-bolts 2 to the waIl 15 and a f;n~l
adjustment oF the uprights 1 position, th~n a
t;ghtening of the Pixing means 13;
- app1i~ation of the cr~ossbars 3 to tha uprights
1, throu~qh the fixing me~ns 16, to cIafina tha
spacas destined to house the t;les 4;
- ~itting ;nsartion of th~ tiles 4 between the
