The ends of the ribs of these cavity bounding profiles are rounded to prevent damage to the webs.

From patent RU 41044 U1, IPC E04B 9/00, publ. 10.10.2004, a profile for a stretch ceiling is known, made in the form of an integral part made of PVC or aluminum alloy from AD31, containing a horizontal shelf, a short central rib and two side ribs forming two open cavities for harpoons, while the side ribs are placed with inclined to the central rib, and the central rib is made with inclined side surfaces, each of which is parallel to the corresponding inner surface of the side rib.

In the description of patent RU 41044 U1 it is indicated that in the manufacture of a profile made of PVC, it is necessary to increase approximately two times (with respect to the profile made of aluminum alloy) the thickness of the loaded elements.

From the description to FIG. 8 patent RU 41044 U1 known design for a two-level stretch ceiling, including the profile described above and attached to it a Z-shaped profile made of PVC or aluminum alloy.

The profile described in patent RU 41044 U1, specialists in the installation of suspended ceilings are called the separator, and the Z-shaped profile is called the Z-shaped chipper.

The design of the separator and the Z-shaped chipper connected together allows the transition of a multi-level stretch ceiling.

An embodiment of a separator for interfacing with a decorative insert is described in patent RU 54064 U1, IPC E04F 19/00, 9/00, publ. 06/10/2006. The profile includes a horizontal shelf with a central V-shaped rib and two inclined side ribs that form open cavities for harpoons to create stretch ceiling cloths. In this case, the central rib is made with inclined side surfaces, each of which is parallel to the inner surface of the opposite side rib and has projections for interacting with harpoons of the stretch ceiling paintings. The edges of the inner surfaces of the side ribs are rounded.

From patent RU 2463414 C1, IPC E04B 9/30, publ. 10/10/2012, the profile for creating a multi-level stretch ceiling is known, made in the form of an integral part made of PVC or aluminum alloy with two cavities for harpoons open upwards, and a protrusion is made at the end of the rib bounding one of the cavities.

From patent RU 111170 U1, IPC E04B 9/30, publ. 12/10/2011, the profile for suspended ceilings is known, made in the form of a single piece and includes a base with three inclined walls. Two cavities are formed in the profile for attaching harpoons of stretch ceiling webs, while the central wall is provided with protrusions and is connected by a stiffener to one of the side walls.

From patent RU 147140 U1, IPC E04B 9/30, publ. 10.27.2014, an aluminum profile for stretch ceilings is known, containing the upper horizontal and lower shelves, as well as the front and rear vertical shelves between them, while the front shelf has an open cavity with a separator for harpoons of stretch ceiling paintings, the profile is equipped with protrusions limiting the cavity on the front side, and at the junction of the vertical front shelf with the lower shelf, a protrusion is made for bending the stretch ceiling web. Moreover, in the upper horizontal shelf can be performed along its entire length of risk under the fasteners.

For the closest analogue of the claimed utility model adopted profile for the installation of a multi-level stretch ceiling, see patent RU 120674 U1, IPC E04B 9/30, publ. 09/27/2012, obtained by extrusion in the form of an integral part and containing a horizontal shelf, front and rear vertical walls, a lower wall connecting the vertical walls, and an open cavity to accommodate and hold two harpoons of stretch ceiling paintings. The implementation of the aluminum alloy profile described in patent RU 120674 U1 is known, see the “Prozet” profiles description by the link on the Internet http://www.prozet.ru/prozet.pdf.

The advantage of the closest analogue is the reduction in the number of components when performing a multi-level transition. In particular, compared with the construction shown in FIG. 8 of the description of patent RU 41044 U1, there is no need to use a Z-shaped chipper.

The closest analogue has numerous disadvantages.

Among them, one can note the high cost of manufacturing, excessive stiffness of the profile.

A significant drawback is the increased complexity of profile refinement in the manufacture of multi-level ceiling structures with non-linear contours. The process of finalizing the analog profile is described in detail in patent RU 2517744 C1, IPC E04B 9/06, publ. 05/27/2014 and includes the implementation of through slots on the rear wall of the profile, after which the profile is bent to obtain the desired bypass line, the aluminum alloy bandage band is placed next to the rear wall, and the bandage band is attached to the rear wall of the profile using self-tapping screws.

The aluminum alloy profile during installation stains the walls, especially if they are glued with wallpaper.

It is unsafe to use a profile made of aluminum alloy from the point of view of electrical safety, since when making holes in the wall or ceiling and getting the drill into the wiring, electricians may be shocked by pressing the profile with their hands.

The disadvantage of the closest analogue can also be considered the impossibility of finalizing the profile during the installation of ceiling structures in order to reduce its height.

The design of the profile according to patent RU 120674 U1, in the case of its execution by extrusion of PVC, has insufficient strength and is subjected to warpage. In addition, it has such a disadvantage of an analogue as the inability to modify the profile during the installation of ceiling structures in order to reduce its height.

The objective to which the utility model is directed is to create a PVC profile design for a multi-level stretch ceiling to replace the aluminum profile known from RU 120674 U1, which is characterized by reduced installation labor, installation resistance, increased installation convenience, as well as advanced features application.

The technical results that the utility model aims to achieve are to change the profile design known from RU 120674 U1 in order to make its analogue from PVC, to reduce the complexity of installation, to reduce the complexity of finalizing the profile in the manufacture of multi-level ceiling structures with non-linear contours, in increasing resistance to deformation during the installation of a stretch ceiling, as well as the possibility of reducing the height of the profile during installation.

The above technical results are achieved in the profile obtained by extrusion and containing the rear side wall, the upper horizontal shelf with a platform protruding from the rear side wall, the front side wall, divided by a slot into the upper and lower parts, the lower shelf, and also a separator for holding harpoons of stretch ceiling cloths, the base of which is the rear side wall, with a V-shaped short dividing wall, on the outer surfaces of which there are protrusions-hooks for harpoons, and two boundary walls inclined toward the partition wall, one edge of each boundary wall being connected to the surface of the rear side wall, and the other to the edge of the slot made on the front side wall, so that the slot acts as an entrance to the separator cavity for harpoons.

The indicated technical results are achieved in that the profile is made of PVC, the upper horizontal shelf is provided with a platform protruding outward from the side of the front side wall, the upper part of the front side wall is inclined at an acute angle to the upper horizontal shelf, the lower part of the front side wall located between the slot and the lower shelf is made concave, and the side walls are connected by a horizontal partition.

In a preferred embodiment, further structural improvements can also be made.

A protrusion can be made on the outer surface of the front side wall near the horizontal partition.

On the surfaces of the back and front side walls below the horizontal partition, marking elements can be made, for example, in the form of protrusions and / or grooves.

The outer surface of the upper horizontal shelf may be risky.

On the surfaces of the first and second platforms of the upper horizontal shelf, marking elements for fasteners, for example, in the form of protrusions and / or grooves, can be formed.

The bends of the back side wall can basically repeat the bends of the front side wall.

In the spacer, a V-shaped short spacer wall may be connected to the boundary walls by jumpers.

The utility model can be successfully implemented in a design, profile, which includes (see Fig. 1, 2) the rear side wall 1, the upper horizontal shelf 2 with the platform 3 protruding from the rear side wall 1, the front side wall 4, divided a slot 5 on the upper 6 and lower 7 parts, the lower shelf 8, as well as the spacer 9 for the stretch ceiling, the base of which is the rear side wall 1, with a V-shaped short dividing wall 10, on the outer surfaces of which there are hooks for hooks, and with two tilted to the dividing wall by the restrictive walls 11, 12, and one edge of each restrictive wall 11, 12 is connected to the surface of the rear side wall 1, and the other to the edge of the slot 5 made on the front side wall 4, so that the slot 5 performs for the harpoons of the tension panels ceiling role of the entrance to the cavity of the separator 9.

To implement the utility model, the following design changes are made.

The profile is performed by extrusion from PVC. The thickness of the material for different grades of PVC is determined empirically.

The PVC profile is significantly cheaper than the aluminum alloy profile, it is easy to process and assemble, it does not stain the ceilings and walls during installation. Its use increases the safety of installing a stretch ceiling by eliminating electric shock through the profile for installers, for example, if a drill gets into the electrical wiring while making a hole in the wall or ceiling.

The upper horizontal shelf 2 is provided with a second platform 13, protruding outward from the profile from the side of the front side wall 4.

The second platform allows you to prevent deformation of the profile inside the formed ceiling ledge during installation of the stretch ceiling canvas.

The upper part 6 of the front side wall 4 is placed at an acute angle a ° to the upper horizontal shelf 2. The location of the upper part 6 of the front side wall 4 at an acute angle a ° to the upper horizontal shelf 2 allows to increase the profile stability under tension of the ceiling sheet.

The lower part 7 of the front side wall 4, located between the slot 5 and the lower shelf 8, is concave.

This embodiment of the lower part 7 allows you to ensure the indentation of the canvas of the lower level of the stretch ceiling from the surface of the front side wall 4 of the profile to improve the appearance of the ceiling.

The side walls 1.4 are connected by a horizontal partition 14.

The presence of a horizontal partition 14 allows you to eliminate warpage of the walls of the profile, increase its rigidity and, if necessary, obtain a profile with a reduced height.

In a preferred embodiment, further structural improvements can also be made.

On the outer surface of the front side wall 4 near the horizontal partition 14, a protrusion 15 can be made.

The protrusion is used in case of removal of the lower part of the profile (see Fig. 4) to ensure the indentation of the canvas of the lower level of the stretch ceiling from uneven surfaces of the profile to improve the appearance of the ceiling.

On the surfaces of the rear and front side walls 1, 4 below the horizontal partition 14, marking elements 16, 17 can be made, for example, in the form of protrusions and / or grooves.

Marking elements 16, 17 facilitate the removal of the bottom of the profile to obtain a profile with a reduced height.

On the outer surface of the upper horizontal shelf 2, risks 18 can be fulfilled.

Risks 18 improve the adhesion of the profile to the ceiling and reduce the possibility of its slippage or displacement.

On the surfaces of the first and second platforms 3, 13 of the upper horizontal shelf 2, marking elements 19, 20, for example, in the form of protrusions and / or grooves, for fasteners can be made.

The presence of marking elements 19, 20 (protrusions and / or grooves) reduces the complexity of mounting the profile.

The bends of the back side wall 1 can basically repeat the bends of the front side wall 4.

The execution of the side walls curved allows you to increase the rigidity of the profile.

In the spacer 9, the V-shaped short spacer wall 10 can be connected to the boundary walls by jumpers 21, 22.

Jumpers increase the rigidity of the spacer used to secure harpoons.

The profile is used as follows.

On the ceiling, mark the future transition of the ceiling. The profile is laid out along the marking line and fixed on the ceiling with fasteners. The holes for the fasteners are performed, guided by the marking elements 19, 20 (protrusions and / or grooves). Install the canvas of the lower level of the stretch ceiling; at the same time, harpoons of one side of the canvas are mounted on the wall of the room using the corresponding profile, then harpoons of the second side of the canvas are installed in the lower part of the cavity of the separator 9. Similarly, the canvas of the upper level of the stretch ceiling is fixed.

In the manufacture of multilevel ceiling structures with non-linear contours in the rear wall of the profile, small incisions are made, which eliminates the need for a retaining tape.

If desired, the height of the profile can be reduced. For this, the profile is cut off, guided by the marking elements 16, 17 (protrusions and / or grooves) and a profile with a reduced height, shown in FIG. 4. The front side wall 4 with the protrusion 15 in the profile with a reduced height perform the role of a chipper blade stretch ceiling.

The conducted patent studies confirm the world novelty of the utility model.

The operation of the prototypes of the utility model confirmed its industrial applicability and compliance with the stated technical results.
