[0001] The present invention relates to an anchoring system for false ceilings.
[0002] Anchoring systems are known in the building industry to anchor a plasterboard false
ceiling to a ceiling of a building, in such a way to create an empty space for passing
a plurality of cables of various types.
[0003] The anchoring system comprises a plurality of threaded rods disposed in parallel
position that are anchored to the ceiling and protrude downwards from the ceiling.
[0004] For each threaded bar, the anchoring system also comprises a coupling bar that is
screwed into a lower free end of the threaded rod, and is connected to a supporting
bracket anchored to a section that partially defines a supporting frame for a false
ceiling.
[0005] The supporting bracket has an upper ring that is engaged with a maneuvering head
of an adjustment screw screwed in the coupling bar, and is additionally provided with
a lower foot that is slidingly coupled with the section, and is blocked on the section
by means of a blocking device.
[0006] The anchoring systems for false ceilings of the prior art are impaired by some drawbacks
that are mainly caused by the fact that the blocking devices that are normally used
to block the supporting brackets on the sections are relatively complicated and expensive,
and do not guarantee a reliable blocking.
[0007] The purpose of the present invention is to disclose an anchoring system for false
ceilings that is deprived of the aforementioned drawbacks, is simple and inexpensive
to make.
[0008] According to the present invention, an anchoring system for false ceilings is disclosed,
as claimed in the appended claims.
[0009] The present invention is described with reference to the appended drawings, which
illustrate a non-limiting embodiment, wherein:
Fig. 1 is a diagrammatic side view of a preferred embodiment of the anchoring system
of the present invention;
Fig. 2 is a diagrammatic perspective view of a first detail of the anchoring system
of Fig. 1;
Fig. 3 is a diagrammatic perspective view of the mounting system of a second detail
of the anchoring system of Fig. 1; and
Fig. 4 is a diagrammatic perspective view of a detail of Fig. 3.
[0010] With reference to Figs. 1, 2 and 3, an anchoring system 1 used for anchoring a false
ceiling 2, in particular made of plasterboard, to a ceiling 3 of a building is disclosed.
[0011] The anchoring system 1 comprises a plurality of anchoring rods 4 disposed in parallel
position and anchored to the ceiling 3 according to the prior art, protruding downwards
from the ceiling 3.
[0012] For each rod 4, the anchoring system 1 also comprises a coupling bar 5 that is provided
with a longitudinal axis 6, and is axially limited by two ending sides 7 that are
substantially perpendicular to the axis 6.
[0013] The bar 5 has two threaded cavities 8, and each of them opening outwards in correspondence
of a relative side 7, and being a blind cavity limited by a bottom wall (not shown)
that is substantially perpendicular to the axis 6.
[0014] The upper cavity 8 is screwed into a lower threaded end of the rod 4, whereas an
adjustment screw 9 with a polygonal maneuvering head 10 is screwed into the lower
cavity 8.
[0015] The anchoring system 1 also comprises a supporting bracket 11 provided with an upper
ring 12 that is revolvingly coupled with the screw 9 in axially sliding mode, protrudes
downwards from the ring 12, and is provided with a lower foot 13.
[0016] The head 10 defines a lower end stop suitable for axially stopping the ring 12 and
consequently the bracket 11, which is coupled with the bar 5 with the interposition
of a shock-absorbing spring 14.
[0017] As shown in Figs. 3 and 4, the foot 13 is anchored to a section 15 that partially
defines a supporting frame 16 of the false ceiling 2, has a U-shape and is limited
by two external sides 17 that are substantially disposed in parallel opposite position.
[0018] Moreover, the section 15 comprises two upper edges 18 that are folded over in such
a way to define a pair of guides that are slidingly engaged by the foot 13.
[0019] The foot 13 is blocked on the section 15 by means of a blocking device 19 comprising
an anchoring plate 20 that comprises an anchoring fork 21 coupled with the section
15 and an anchoring tab 22 coupled with the bracket 11.
[0020] The fork 21 has a substantially planar shape, is provided with two anchoring arms
23 disposed on opposite sides of the section 15 and additionally comprises a central
tooth 24 disposed between the arms 23 and engaged in the foot 13 of the bracket 11.
[0021] Each arm 23 is provided with a toothed section 25 that is frictionally coupled with
a relative side 17 of the section 15.
[0022] The tab 22 extends in perpendicular direction relative to the fork 21, is engaged
in a slot 26 obtained through the bracket 11, and has a larger maximum width than
the slot 26.
[0023] With reference to Fig. 3, the bracket 11 is blocked on the section 15 by inserting
the tab 22 in the slot 26 (Figs. 3a and 3b), rotating the plate 20 by 90° (Fig. 3c),
and lowering the plate 20 in such a way to engage the tooth 24 in the foot 13 and
frictionally couple the toothed section 25 of the arms 23 with the sides 17 (Fig.
3d).
[0024] The engagement of the tab 22 in the slot 26 and the toothed section 25 of the arms
23 guarantee a firm and safe blocking of each bracket 11 on the section 15.
