| (54) | Improved panel for false ceilings |
| (57) An improved panel consisting of a plate (2) with its four edges bent at 90°, the
edges h.aving their ends (8, 8') cut to a determined shape, wherein: the end (8) is cut to form: - a lower rectangular appendix (12) of dimensions I x h, - an upper rectangular appendix (14) of dimensions c x b, - an L-shaped segment (16) of dimensions z x s, - a segment joining the end Q of the L-shaped segment (16) to the upper end of the appendix 12 and having a height "a" such that h+a+z+b corresponds to the height H of the bent edge (6), this segment assuming different shapes depending on the angles α and β which the segment forms respectively with the vertical passing through the point P of the appendix (12) and with the horizontal passing through the point Q of the L-shaped segment (16), the end (8') presenting: - a lower rectangular appendix (18) of dimensions n x h, - a second upper appendix (20) of dimensions b x c, and - a segment (22), joining the point R to the point S, which is of height t = a+z . |
[0002] Structural elements for false ceilings are known consisting of profiles of inverted T cross-section provided at their end with coupling elements either formed directly in the central web of the T-profile or formed separately and applied to each profile section during its manufacture.
[0003] In a central region of the web, these profiles comprise slots in which the coupling element of a profile perpendicular thereto engages so as to be able to form a lattice structure which is suspended from the ceiling, generally by steel hangers, and which, by means of the horizontal flanges of the profiles, functionally supports panels and/or staves or whatever else is required to form the false ceiling.
[0004] The object of the invention is to provide a panel which is highly reliable in its connection to the T elements, such as to present anti-disengagement characteristics.
[0006] The present invention is further clarified hereinafter with reference to the accompanying drawings, in which:
Figure 1 is a perspective view of a panel,
Figure 2 shows the end of two panels anchored to a T element,
Figure 3 is a longitudinal section through one end of the panel,
Figures 4 and 5 show two different forms of said end,
Figure 6 is a longitudinal section through the other end of the panel.
Figure 7 shows a different form of this latter end,
Figure 8 shows six steps in coupling the panel to the T-profile, and
Figure 9 shows a modified embodiment of the panel.
[0007] As can be seen from the figures, the improved panel of the invention comprises a plate 2 with its four edges 4, 4', 6, 6' bent at 90°, the edges 6, 6' having their ends 8, 8' cut to a certain shape.
[0008] Specifically, the end 8 is cut such as to form:
- a lower rectangular appendix 12 of dimensions I x h,
- an upper rectangular appendix 14 of dimensions c x b,
- an L-shaped segment 16 of dimensions z x s,
- a segment joining the end Q of the L-shaped segment 16 to the upper end P of the appendix 12 and having a height "a" such that h+a+z+b corresponds to the height H of the bent edge 6.
[0009] This segment assumes different shapes (see Figures 3, 4 and 5) depending on the angles α and β which the segment forms respectively with the vertical passing through the point P of the appendix 12 and with the horizontal passing through the point Q of the L-shaped segment 16. The values of the parameters are defined as follows (expressed in millimetres):
[0010] The end 8' presents a lower rectangular appendix 18 of dimensions n x h, a second upper appendix 20 of dimensions b x c, and a segment 22, joining the point R to the point S, which is of height t = a+z with n = m+Δ, where Δ lies between 0 and 4, and 80° < γ <83°.
[0011] The panels formed in this manner are then connected to the inverted T-profile as shown in Figure 8, from which it can be seen that after arranging the individual panels 2 between the various inverted T-profiles by resting the ends 8, 8' on the flanges 26 of these profiles, the final closing panel is inserted by a succession of steps comprising:
1 inserting the appendix 12 into the groove 28 of the end 8';
2) then inserting the appendix 18 into the groove 30 of the end 8;
3) translationally moving the panel such that the appendices 14 and 20 become positioned above the flanges 26 of the T-profile;
4) lowering the panel so that the appendix 14 rests on the flange 26;
5) translationally moving the profile;
6) resting the profile on the flanges.
the end 8 is cut to form:
- a lower rectangular appendix (12) of dimensions I x h,
- an upper rectangular appendix (14) of dimensions c x b,
- an L-shaped segment (16) of dimensions z x s,
- a segment joining the end Q of the L-shaped segment (16) to the upper end of the appendix 12 and having a height "a" such that h+a+z+b corresponds to the height H of the bent edge (6),
this segment assuming different shapes depending on the angles α and β which the segment forms respectively with the vertical passing through the point P of the appendix (12) and with the horizontal passing through the point Q of the L-shaped segment (16),
the values of the parameters being defined as follows (expressed in millimetres):
the end 8' presenting:
- a lower rectangular appendix (18) of dimensions n x h,
- a second upper appendix (20) of dimensions b x c, and
- a segment (22), joining the point R to the point S, which is of height t = a+z with n = m+Δ, where Δ lies between 0 and 4, and 80° < γ <83°.
