EA027952B1 - Moulding for fastening a tensioned canvas - Google Patents

Abstract

The invention is related do design of false ceilings such as decorative suspended ceilings, and partitions such as decorative walls of tensioned canvas. The objective of the present invention is provision of a moulding for a decorative partition that can be actually considered as invisible after mounting a tensioned canvas. Such invisibility is achieved without using any finishing element, and the moulding provides quick and reliable installation of a decorative partition in the place of canvas, and has a sufficiently simple structure to remain inexpensive. The new design of the moulding allows installation of multi-layer ceilings of complicated shape providing interesting and varied illumination. The objective is attained by providing edges of the channel in the form of a cylindrical bar protruding above the plane of the moulding, and by the moulding having an additional channel to accommodate the illumination band. There are also other distinctions from the prior art.

Description

The invention relates to the construction of false ceilings, such as decorative suspended ceilings, and partitions, such as decorative walls made of stretched fabric.

To fix the stretch fabric to the ceiling or walls, various construction devices (baguettes) are used, which are fixed respectively to the ceiling or walls. Typically, a baguette has the form of a structural structural part in which a longitudinal gutter of an I- or V-shape is made to place and fasten a canvas in it, attached to a longitudinal part fixed in the longitudinal hole of the baguette. This embodiment of the baguette allows you to conveniently and reliably fasten the edges of the canvas, hiding all elements support and fastening and practically without leaving visible cracks.

Further development of the design of ceilings, especially multi-level ceilings, required the development of more complex design of baguettes [3]. The patent adopted for the prototype describes a profile for mounting a multi-level stretch ceiling, containing at least one open cavity for attaching and securing the borders of adjacent paintings in it, made in the form of a one-piece integral part and containing a horizontal mounting shelf perpendicular to it front and rear vertical walls, external protrusions located along the extreme upper and lower edges, restricting the open cavity on the front side of the profile, while the horizontal mounting shelf is located yshe open cavity, the front and rear vertical walls are interconnected by a bottom wall, and the bottom front vertical wall is further configured bottom lip.

The disadvantage of the prototype is the complexity of its use in curved structures.

The problem to which the present invention is directed, is to create such a baguette for a decorative partition, which can actually be considered invisible after installing the stretched fabric. At the same time, such inconspicuity is achieved without the use of any finishing element, and the profile provides a quick and reliable installation of a decorative partition in place of the canvas and has a sufficiently simple structure to remain inexpensive. At the same time, the new design of the baguette allows for multi-level ceilings of complex shape, providing an interesting and varied decorative lighting.

The problem is solved in that in a baguette for attaching a stretched web made in the form of a molded box-shaped part with an upper shelf for fastening to a ceiling containing a front face and a rear wall with protrusions, two longitudinal I-shaped or ν-shaped gutters for placing and securing in it horizontal and vertical web, which are provided with external protrusions along the upper and lower edges of the said grooves and limit the open cavity on the wall from the front side, according to the invention The wall with protrusions in the lower part has a rounded cylindrical shape, and the baguette contains a dovetail shaped gutter for installing backlight elements, and the edges of the upper and lower edges of the longitudinal gutters of the I-shaped or ν-shaped are made in the form of a cylindrical rod that protrudes from the front side of the front wall above the baguette plane by the value of the radius of the cylindrical bar.

The cylindrical bar is made with a radius of 3-7 mm.

A dovetail-shaped gutter for installing backlight elements is made on the rear wall with protrusions, or on the front front side of the wall, or between the longitudinal grooves of the Uniform shape on the front side of the wall.

On the inner side walls of the grooves of the box-shaped part, open holes are made for installing docking pins when connecting several baguettes.

The invention is illustrated by drawings.

In FIG. 1 shows a baguette profile with cylindrical rods protruding above the baguette plane; in FIG. 2 - a profile of a baguette with an additional trough for installation of a tape of illumination; in FIG. 3 - profile baguette with an additional groove for the backlight tape from the side opposite from the mounting of the canvas; in FIG. 4 is a profile of a baguette with an additional groove for a backlight tape located between longitudinal V- or U-shaped grooves for attaching the web; in FIG. 5 profile baguette with a cylindrical lower part made along the radius; in FIG. 6 - profile baguette with the lower part made with faces; in FIG. 7 - profile baguette with a hole in the side surface of the gutters.

The baguette is made in the form of a molded box-shaped part, for example, of aluminum and contains an upper shelf 1 for attaching to the ceiling, two longitudinal gutters of a V- or I-shape 2 and 3 for attaching the ceiling web and for attaching the web directed downward. The edges of the grooves are made in the form of a cylindrical rod 4, protruding above the plane of the baguette and serving to bend around it with a stretched canvas. On the back wall of the baguette, guiding projections 5 are made for guiding a docking bar (not shown). Such a bar is necessary for connecting individual baguettes into a continuous support of the desired length, or when the baguette is incised when it is bent. The protrusions 5 also give additional rigidity to the baguette. For the same purpose, two L-shaped protrusions 6 are placed inside the baguette. A docking bar (not shown) can be held in them without being fixed. In a baguette by

- 1 027952 of the invention made an additional longitudinal groove 7 for installing backlight elements (not shown). As such elements, LED lamps or other light sources can be used. In particular, a decorative LED strip can be used. The execution of the trough for illumination in the form of a dovetail allows you to avoid additional fastening elements of the tape. Installing the backlight tape between the mounting grooves 2 and 3 allows you to get the light distributed along the canvas. Installing the backlight tape in other places allows you to significantly diversify lighting effects and use the transparency and translucency of the canvas in the design of ceilings and walls.

The execution of the edges of the grooves in the form of a cylindrical rod 4 allows you to keep the bending line of the canvas flat and smooth, regardless of the bending of the baguette. This cannot be achieved when the edges of the gutters are a right angle. Holes 8 are made in the side walls of the gutters, which can be made open for installing docking pins when several baguettes are connected in one line. Making holes 8 open allows you to install the docking pins with an interference fit without the use of presses. The holes in the side walls of the gutters for attaching the web allows you to very accurately join the gutters for attaching the web in adjacent profiles.

The radius of the cylindrical protrusion is determined empirically in the range from 3 to 7 mm. With a radius of more than 7 mm, the baguette turns out to be heavy enough and tough to install complex-profile multi-level ceilings. With a radius of less than 3 mm, the wire effect disappears and jams are possible when the baguette is bent. The protrusion of the bar by the size of the radius of the cylindrical protrusion allows the baguette to prevent the canvas from touching the surface of the baguette, thereby concealing any technological irregularities, scratches, holes, bends of the baguette. Thanks to this embodiment, the canvas does not touch the surface of the baguette.

The execution of the bottom of the baguette cylindrical or with faces also allows you to expand the range of use of design solutions. You can move away from traditional rectangular transitions from vertical to horizontal, and use fillet and smooth transitions. This allows you to create completely new designs of multilevel ceilings with smooth transitions from horizontal to vertical.
