IMPROVED SEPARATING SCREEN FOR FASTENING CANVAS WITHOUT MEANS OF HITCHING

TECHNICAL FIELD OF THE INVENTION

[001] The invention relates to the technical field of false ceilings and false wall tension.

[002] The invention relates more particularly to a smooth for the assembly of two webs without attachment means for the realization of a false-walled stretched canvas.

STATE OF THE ART

[003] It is common, when the surfaces of the ceilings or wall walls are important, to have across the latter smooth dividers, also called double smooth, to assemble and maintain coplanar two stretched canvases.

[004] In conventional manner, the separating beams have two wings delimiting a receiving space for receiving the borders of the two canvases to be assembled. When the canvases to be assembled comprise a hooking means, the receiving space comprises two receiving grooves respectively arranged to allow the hooking of a canvas via the harpoon with which it is provided. When, on the contrary, the canvases to be assembled do not comprise means of attachment, the stringer comprises a means ensuring a joint fixing of the two canvases by clamping, the borders of the latter being arranged in one and the same space.

[005] The smooth implemented for fixing webs by pinching however have drawbacks.

[006] One of the major drawbacks is the removal of the paintings. Indeed, because the edges of the two canvases are placed in a single space, it is not possible to remove a canvas without removing the other canvas with which it is assembled. The access to the plenum or the replacement of a fabric for example imposes to unhook the two canvases. Moreover, the fabrics devoid of means of attachment are mainly textile fabrics without elasticity. During the installation of the false wall, the paintings used are leveled to ensure a quality finish. However, once disassembled, the canvases can no longer be placed in position on the rail due to lack of material following the leveling made on the one hand and the lack of elasticity of the fabrics on the other hand.

[007] The invention aims to remedy these problems by providing a separating smooth for the assembly of two webs devoid of attachment means for the realization of a false-walled stretched canvas, which allows to unhook the smooth two canvases independently of one another.

[008] The invention also aims to provide a smooth allowing quick and easy assembly and disassembly of the two canvases independently of one another.

[009] The invention also aims to provide a false ceiling with such a separating smooth.

OBJECT OF THE INVENTION

For clarity, identical or similar elements of the different embodiments are identified by identical reference signs throughout the figures.

In what follows, we define the terms "vertical" and "horizontal" with respect to the position of the rails shown in the figures.

DETAILED DESCRIPTION OF THE FIGURES

In connection with Figure 1, there is described a smooth separator 1 for the realization of a false-walled stretched canvas.

The smooth 1, formed of a profile or abutting profiles, comprises two lateral wings 2, 4, preferably of the same length, interconnected by a wall, said bottom wall 5, and extending from the wall background towards each other. Advantageously, the lateral wings 2, 4 are inclined relative to the vertical axis at an angle of between 5 degrees and 45 degrees.

The arm 1 further comprises a third wing 3 extending vertically between the lateral wings 2, 4, from the bottom wall 5.

The lateral wings 2, 4, the bottom wall 5 and the third flange 3 define respectively two grooves 6, 8 each having an access opening 16, 18 facing downwards. In the following, we will name the third wing 3 separation wing 3. The wing separation 3 extends to have a substantially coplanar end with the free ends 20, 40 of the lateral wings 2, 4 (converging ends) . The access openings 16, 18 at each groove are thus made distinct and independent of one another. In other words, they open directly to the outside of the rail 1. The spacing between the lateral wings 2, 4 and the separation wing 3 will be defined to ensure access openings 16, 18 sufficient to allow the passage of the canvases in the grooves 6, 8.

The separation wing 3 has two shoulders 10, 11, one of the shoulder 10 being formed to extend on the side of the groove 6, the other shoulder 11 being formed to extend to the side of the 8. The shoulders are arranged symmetrically with respect to the separation wing 3. They constitute retaining means for retaining an accessory profile 60, 80 in each of the grooves 6, 8, which accessory section 60, 80 is a profile additional intended to ensure the attachment by pinching a canvas without attachment means. FIG. 2 shows the rail 1 equipped with such accessory profiles 60, 80 housed in each of the grooves 6, 8.

Each accessory section 60, 80, advantageously made of PVC, is arranged to fully fit into one of the grooves 6, 8 of reception. More particularly, each accessory profile 60, 80 is arranged to fit the inner contour of the associated groove in which it is intended to be placed. In the illustrated embodiment, each accessory profile 60, 80 has a U-shaped cross section, one of the U-shaped arms being sized to extend, when the accessory profile 60, 80 is clipped into the associated groove. , on the height of the lateral flange of said groove, the other arm of the U-shaped having a defined height to abut on the shoulder of the inner wing.

The arm of the accessory section 60, 80 placed against the side wing is provided with tabs 61, 81 semi-rigid or flexible arranged to abut against the wing separation. The tongues 61, 81 are configured to maintain the edge of the web inserted in the groove in which the accessory profile is placed, by pinching on the separating wing 3. In the example illustrated, the nip is made on the portion of the separation wing 3 located between the shoulder and the free end of said separation wing 3. Advantageously, the tongues 61, 81 are made of semi-rigid or flexible polymer. This allows to ensure a pinch of the canvas sufficient to ensure the retention of the canvas without damaging it.

The insertion of the accessory profile 60, 80 in the associated groove 6, 8 is made possible because of its U-shaped, its implementation being effected by elastic casing in said grooves of the smooth 1.

In the illustrated embodiment, the shoulders 10, 11 are arranged to define a bearing surface located substantially midway from the end defining the access openings 16, 18 and the bottom wall. 5.

The separation wing 3 further has a tapered shape towards the access openings 16, 18. This has the advantage of reducing the gap between the two canvases when they are fixed on the rail, and to make the latter invisible.

Advantageously, the rail has two wings 7, 9 for fixing said rail to a wall. In the embodiment illustrated in Figures 1 and 2, the fixing wings 7, 9 extend horizontally, in the extension of the bottom wall 5, on either side of the latter. According to another embodiment of a separating arm illustrated in FIG. 3 (smooth 100), the fixing wings 7, 9 extend vertically, in the extension of the lateral wings 2, 4, in the opposite direction of the third wing 3, to be attached to a stirrup 12 provided with a tie 13 secured to the ceiling of the room.

The invention is described in the foregoing by way of example. It is understood that the skilled person is able to achieve different embodiments of the invention without departing from the scope of the invention.
