[0001] This invention relates to a façade of a building provided with a disappearing lighting
element such that it does not interfere with the appearance of the façade in particular
during daytime.
[0002] The realization of façade lighting systems usable for example in nighttime hours
to produce plays of light and special aesthetic effects on the building is known in
the art.
[0003] Know lighting systems however generally include a plurality of floodlights fastened
on the outer façade of the building and remaining exposed even when not in use. These
lights, indeed, can ruin the aesthetic appearance of the façade and remain continuously
at the mercy of bad weather or possible vandalisms.
EP 0 921 253 A contains the preamble of claim 1.
[0004] BE 1013381 A3 discloses a movable panel containing a light source, which is housed in a niche in
a wall and can be rotated to project outside the wall surface to illuminate the wall
or the ceiling.
[0005] The general purpose of this invention is to remedy the above mentioned shortcomings
by making available a façade provided with a lighting system that does not interfere
with the overall aesthetic effect produced by the building and in particular in daylight
hours.
[0006] Another purpose of this invention is to make available a lighting system such that
the light source would remain exposed to bad weather or vandalism as little as possible.
[0007] In view of this purpose it was sought to provide in accordance with this invention
a building façade according to claim 1.
[0008] To clarify the explanation of the innovative principles of this invention and its
advantages compared with the prior art there is described below with the aid of the
annexed drawings a possible embodiment thereof by way of non-limiting example applying
said principles. In the drawings:
FIG 1 shows a view of a façade part having a lighting system in accordance with this
invention,
FIG 2 shows a side view of the lighting element of the façade with hidden light source,
FIG 3 shows another side view of the façade lighting element configured to illuminate
the building, and
FIG 4 shows a rear view of the lighting element inside the façade.
[0009] With reference to the figures, FIG 1 shows part of a façade 11 of a building including
a plurality of modular covering panels 12 for example rectangular tiles made of ceramic.
[0010] The panels 12 are virtually coplanar with each other and define the surface of the
façade 11. The panel 13, which can be sized identically to the panels 12, is movable
between a protruding position inclined to the façade surface (shown in FIG 1) and
a position coplanar with the façade plane.
[0011] When the panel 13 is in the protruding position, in the space between the panel and
the façade surface there is at least one light source 14 oriented with the light beam
toward the building façade. Two light sources realized in accordance with the prior
art are shown in the example of FIG 1.
[0012] In the protruding position the movable panel 13 could be inclined to the vertical
surface by an angle of between 5° and 30° which would be enough to allow the light
source to illuminate the building façade 11.
[0013] In one realization of this invention the light sources 14 are housed in a supporting
frame or structure 15 to which the movable panel 13 is fastened.
[0014] The supporting frame 15 together with the light source 14 and the movable panel 13
make up the façade element designed to supply the façade lighting.
[0015] FIG 2 shows a side view of the façade part where the façade element designed for
lighting is arranged and configured with the light source 14 hidden inside the façade.
[0016] In accordance with the prior art contrivances, each covering panel 12 is fastened
to a pair of horizontal support sections 16. The horizontal sections 16 are fastened
to vertical sections 17 which in turn are anchored to the wall 19 of the building
by appropriate clamps 18 also realized in accordance with prior art. Said contrivances
allow forming between the building panels and wall an air space which can be ventilated
if necessary in accordance with known techniques of the building industry.
[0017] The movable panel 13 differently from the panels 12 is fastened to a movable supporting
frame 15 forming a space designed to house the light source 14.
[0018] In one embodiment of this invention the frame 15 has a virtually prismatic form with
an acute triangular cross section. Opposite its narrow part, the frame 15 is hinged
to the support 21 through the horizontal hinge 20. The support 21 is fastened to the
above-mentioned vertical sections 17.
[0019] Opposite its wide part the frame 15 is constrained to the rod 22 for transport. The
rod 22 is moved by the powered driving gear 23 designed to shift the frame 15 between
the retracted position of FIG 2 and the protruding position of FIG 3.
[0020] The driving gear 23 is realized in accordance with the prior art and fastened to
the wall 19 of the building and controlled so as to move the movable panel 13 alternatively
between the position coplanar with the façade surface in daylight hours and the inclined
protruding position in the nighttime hours.
[0021] Advantageously the panel 13 is fastened to the frame 15 so as to rotate around its
lower horizontal edge.
[0022] It is noted that in FIG 3 the wide part of the space 15 is closed by a covering glass
30 designed to project the light source 14 when the panel 13 is in the protruding
position.
[0023] FIG 4 shows the three panels of FIG 2 from the inside of the façade with the handling
rod 22 and the driving gear 23 removed.
[0024] It is noted in particular that the two covering panels 12 are anchored to the horizontal
sections 16 which are in turn fastened to the vertical sections 17. The panel 13 on
the contrary is fastened to the supporting frame 15 which houses the light source
(not shown in the figures). The supporting frame 15 as mentioned above is hinged to
the support 21 and has a width less than that of the panels to be insertable between
the vertical sections 17 when the movable panel 13 is coplanar with the outer panels
12.
[0025] It is now clear that the preset purposes have been achieved. Indeed, when the movable
panel 13 is in the position coplanar with the façade surface the light source 14 is
positioned in the air space between the building wall and the façade without remaining
in view or exposed to vandalism.
[0026] When the movable panel 13 is in the protruding position of FIG 3 the façade is illuminated
while keeping the light source 14 little exposed behind the movable panel 13.
[0027] Naturally the above description of an embodiment applying the innovative principles
of this invention is given by way of non-limiting example of said principles within
the scope of the exclusive right claimed here.
[0028] In an unclaimed embodiment, the light source could be fastened inside the façade
as regards the building and there could be arranged on the movable panel a mirror
to reflect the source light towards the façade when the panel is in the protruding
position.
