DEFORMABLE UPRIGHT FOR FORMING ARCHED FALSE CEILINGS AND NON-LINEAR OPENINGS

Description

[0001] The present invention relates to a deformable upright for forming arched false ceilings and non-linear openings.

[0002] Currently, to form partitions, furnishing walls or false ceilings, metal structures are used, fixed to the masonry, to support panels of plaster board or other similar materials.

[0003] These structures generally consist of a U-bent profile provided with a plurality of apertures to form an assembly of U-shaped modules joined together by appendices provided on the bottom and on the two sides. The appendices are then bent inwards to form a plurality of U-shaped elements joined together by portions of their lower and lateral surfaces.

[0004] During use, each deformable guide is used as it is or is adapted to the curved shape to be produced, by opening out or bending the connection appendices. In particular, the guides are adapted to the plan development of the walls to be formed, are fixed or mounted vertically, fixed at their ends to the floor and ceiling respectively.

[0005] In other cases they are adapted to the development of the ceiling and fixed at their ends to the walls. Curved or flat panels connected together are applied to the guide and upright assembly.

[0006] WO 2013175272 A relates to a deformable guide for partitions, false ceilings and spandrels in general composed of a strip of die-cut sheet metal, cut and folded into a U-shape, having continuous zones alternating with zones with notches and die-cuts.

[0007] This document discloses the technical features of the preamble of claim 1.

[0008] These uprights have however been shown to be susceptible to improvement for their use as arched false ceilings or non-linear openings in partitions.

[0009] This improvement is attained according to the invention by a deformable upright for forming arched false ceilings and non-linear openings as described in claim 1.

[0010] The present invention is further clarified hereinafter in terms of a preferred embodiment thereof, with reference to the accompanying drawings, in which:

Figure 1

shows a perspective view of an upright according to the invention,

Figure 2

shows a portion of the upright according to the invention before being bent to U-shape,

Figure 3

shows it in frontal view,

Figure 4

shows it in partial lateral view, and

Figure 5

is a plan view showing it in curved configuration.

[0011] As can be seen in Figure 2, the upright 2 according to the invention consists of a strip of sheet metal die-cut to form a plurality of modules 4 symmetrical about the longitudinal axis 6 of the upright, each module being provided with two bending lines 8 for forming a U-shaped piece consisting of a base 10 and two flanges 12, with the edges 14 bent inwards and downwards.

[0012] Each module 2 is die-cut to define:

• in the two flanges 12, two apertures 16 of sand-glass shape which cease before the bending line 8 and which extend beyond the bending lines 18 about which the edges 14 are bent relative to the flanges 12,
• in the edge 14, a semicircular incision 20,
• in the base 10, a central incision 22 formed substantially from a elliptical portion 24 which extends at both ends into two slotted apertures 26 aligned with the incisions 20,
• in the base 10, outside the central incision 22, four inclined slotted apertures 28 having one end close to the elliptical portion 24, and the other end close to the ends of the base of the sand-glass shaped aperture 16.

[0013] In particular, the distance between the ends of those slotted incisions 28 closer to the axis 8 substantially corresponds to the width of the sand-glass shaped aperture 16.

[0014] To curve the upright, the zone comprising the central incision 22 has merely to be pressed.
