Description

The claimed group of inventions relates to construction and is used to create interiors of residential and other premises, in particular, to the technology of decorating stretch ceilings made of fabric or polymer materials with decorative elements, such as rhinestones, to improve their aesthetic qualities.

Known decorative element in the form of a rhinestone, taken as a prototype, including a body made in the form of a truncated pyramid with a base in the form of a flat contact surface for attachment to the decorated surface, equipped with a reflective coating (see the description of the utility model to patent No. 91266 "Case for things ", IPC A45S 11/24, publ. 10.02.2010).

The reflective coating of the flat contact surface of the rhinestone is made in the form of a layer of metal applied to the contact surface for better reflection of light from the rhinestone.

The rhinestone is attached to the surface to be decorated with a layer of glue, for example, PVA glue, epoxy, BF, decoupage glue, etc.

Fastening a rhinestone to a deforming surface to be decorated with glue is not reliable, since when the web is deformed at the place of gluing (contact), both the adhesive material itself and the bond between the adhesive material and the web can break, which leads to the peeling of the rhinestone.

Fastening a rhinestone with glue is laborious and, in addition, requires precise dosing of the glue and its exact place of application on the canvas, otherwise the decorated product will not have a high artistic aesthetic quality.

The technical problem and result of the proposed device is to simplify the process of fastening decorative elements to the canvas of stretch ceilings, to increase the reliability of fastening and to reduce the labor intensity of the manufacture of stretch ceilings.

The technical result is achieved in that the decorative element includes a body and a base made in the form of a flat contact surface for attachment to the decorated canvas, while the contact surface has a reflective coating of reflective materials, while it additionally contains a threaded element for fastening made of a conical shape with a blind cylindrical hole in the middle part for installing a fiber optic cable, while the ratio of the outer thread diameter D and the inner thread diameter D ₁ is D: D ₁ in the range from 4/1 to 4/3 with a thread pitch h equal to 0.5-2 mm ... The body of the decorative element is made of glass or polymer material. Epoxy resin or polyester resin or acrylic resin is used as a polymer material. The reflective coating of the decorative element is made of foil or reflective paint.

The presence of a decorative element of a tapered threaded element with a ratio of the outer diameter of the thread D and the inner diameter of the thread D ₁ in the range from 4/1 to 4/3 and a thread pitch in the range of 0.5-2 mm, allows you to keep the decorative element on the surface of the canvas, excluding its loss.

The group of inventions is illustrated by drawings, where: Fig. 1 shows a decorative element, general view; in fig. 2 - installation, general view; in fig. 3 - housing of a modular head for attaching a decorative element; in fig. 4 - removable module for installing a decorative element in assembly with the protective cover removed, initial position; in fig. 5 - removable module for installing a decorative element, complete with a removed protective casing, working position; in fig. 6 - a removable module for installing a decorative element assembled with a removed protective casing, bottom view; in fig. 7 is a sectional view of a device for removing a decorative element; in fig. 8 - cassette with decorative elements, general view; in fig. 9 - a decorative element installed in the canvas on the installation table.

The body of the decorative element 1 is made of any volumetric shape with the base 2 in the form of a flat contact surface for attachment to the surface to be decorated, and a threaded element 3 made with a blind cylindrical hole 4 for installing a fiber-optic cable (the fiber-optic cable is not shown in the drawing).

The threaded element 3 is made in the form of a cone and has a ratio of the outer diameter of the thread D and the inner diameter of the thread D ₁ equal to D: D ₁ in the range from 4/1 to 4/3, and the thread pitch h in the range of 0.5-2 mm.

The base 2 is equipped with a reflective substrate 5 made of reflective materials such as foil or reflective paint.

The decorative element 1 can be made by casting from glass or a polymeric material, for example a molding resin such as epoxy, polyester or acrylic resin.

The decorative element 1 is used to decorate the canvas 6 stretch ceilings during their manufacture.

The technical problem and result of the proposed device is to simplify the process of fastening decorative elements to the canvas of stretch ceilings, to increase the reliability of fastening and to reduce the labor intensity of the manufacture of stretch ceilings.

The technical result is achieved by the fact that the installation for attaching a decorative element to a stretch ceiling canvas contains a cutting table with clamping compartments, a hard cover and at least one device for creating a pressure below atmospheric, with the ability to turn off any clamping compartment, as well as guides for longitudinal movement of carriages, connected by a guide, on which a transverse movement carriage is installed, on which a cutting knife is mounted, mounted with the ability to move across the flooring with the cloth being decorated along a guide, which in turn is mounted with the ability to move along the flooring along the guides, and a drive for moving the carriages, controlled by a computer program , while it additionally contains a removable module for installing decorative elements, fixed on the carriage of lateral movement by means of the case, while the removable module consists of a cassette unit for placing the set vertically installed mounted cassettes in the form of hollow cylinders for placing decorative elements, a mechanical drive for step-by-step movement of the cassette unit, a device for removing decorative elements from the cassette unit and screwing decorative elements into the decorated canvas and devices for punching holes in the canvas for installing decorative elements, while the cassette unit installed in the guides of the removable module body with the ability to move in the horizontal plane from the mechanical step-by-step movement relative to the guides of the removable module body, and the punching device has the ability to move horizontally and vertically from the drive and contains an element for punching holes in the web, and the element for punching holes is made with the possibility of heating for burning holes, while the cutting table cover additionally contains a soft air-permeable substrate, and the rigid flooring is perforated. The punching device can be driven pneumatically, hydraulically or mechanically.

The proposed installation includes a cutting table 7, on opposite sides of which guides 8 and 9 are fixed for the longitudinal movement of the carriages 10. The carriages 10 are connected by the guide 11, on which the carriage 12 is installed with the possibility of transverse movement from the drive for programmed movement along the cutting line (the programmed movement drive on not shown in the drawing). On one side of the carriage 12, the body 13 of the removable module for installing decorative elements 1 is fixed, and on the other side there is a removable cutting knife. The cutting knife can be made, for example, in the form of a rod with an end beveled on both sides (the cutting knife is not shown in the drawing).

The proposed installation provides the ability to decorate the canvas 6 stretch ceilings both with the possibility of cutting a pattern in the canvas 6 and decorating along the contour of the cutouts with decorative elements, not along the contour (in a place free from the cutouts) and decorating the canvas 6 only with decorative elements 1 without cutting the pattern.

The cutting table 7 is equipped with a set of clamping compartments 14, and at least one device 15 for creating a pressure below atmospheric, for example, a vacuum pump connected, for example, by means of hoses to each of the clamping compartments 14 and with the possibility of disconnecting any clamping compartment 14 (hoses and holes not shown in the drawing). For the passage of air between the compartments 14, it is possible, for example, to make through holes in the inner walls of the compartments 14 when the pressure is below atmospheric pressure (through holes are not shown in the drawing).

The covering of the cutting table includes a rigid perforated flooring 16 and a soft breathable backing 17 with a thickness of 4-7 mm to ensure the passage of air when creating a pressure below atmospheric. The decorated canvas 6 of the stretch ceiling, made of PVC or fabric with a thickness of 0.5-1.5 mm, intended for stretch ceilings, is placed (stretched) over the flooring 16 and the substrate 17.

The decoration of the canvas 6 with decorative elements 1 is carried out with a removable module for installing decorative elements 1, the units of which are mounted on the case 13 of a removable module fixed on the carriage 12 of lateral movement.

A removable module for installing decorative elements 1 consists of a cassette unit 18 for placing decorative elements 1, a mechanical drive 19 for step-by-step movement of the cassette unit 18, a device 20 for removing decorative elements 1 from a cassette unit 18 and screwing decorative elements 1 into the decorative canvas 6 and devices 21 for punching holes in the canvas 6 for installing decorative elements 1.

The cassette unit 18 is a cassette holder in the form of a group of vertically placed slots for installing a set of cassettes 22 made in the form of hollow cylinders, inside which decorative elements 1 are placed (the cassette holder is not shown in the drawing). The cassette unit 18 is installed in the guides 23 of the body 13 by means of the skids 24, which can be moved in the horizontal plane from the drive 19 of mechanical step-by-step movement relative to the guides 23.

The device 21 for punching holes has the ability to move horizontally and vertically relative to the body 13 from a pneumatic, hydraulic or mechanical drive 25 and 26, respectively, and contains an element 27 for punching holes in the web 6. The element 27 for punching holes in the web 6 is made with a cross-section in the form of an oval or circle. The length of the element 27 is from 3-8 mm, which excludes the possibility of touching the rigid perforated deck 16.

Element 27 for punching holes in a PVC sheet has the ability to heat to provide the possibility of "burning" holes in PVC for installing decorative elements 1.

The removable module for installing rhinestones is equipped with a protective casing 28.

The installation works as follows.

The decorated canvas 6 of the stretch ceiling is placed on the cutting table 7 over the soft breathable substrate 17 and the pressure is created below atmospheric pressure by the device 15, pressing the decorated canvas 6 with a vacuum against the rigid perforated flooring 16 of the table 7.

Cassettes 22 are pre-filled with decorative elements 1 and placed vertically in a cassette holder, forming a cassette unit 18.

According to a signal from the control unit of the installation using carriages 10 and guide 11, the module for installing decorative elements 1 is positioned at the place of decoration of the canvas 6 (the control unit is not shown in the drawing). Then with element 27 holes are punched in the fabric or holes are burned into PVC. The device 21 performs piecewise removal of decorative elements 1 from the first cassette 22 of the cassette unit 18 and screwing the decorative elements 1 into the decorated canvas 6.

After using the decorative elements 1 in the first cassette 22 with the help of the device 20 for stepwise movement, the cassette unit 18 moves along the guides 23 to the outside of the module housing 13, providing the decorative elements 1 from the second cassette 22.

Depending on the selected pattern, recorded in digital form in the memory of the programmed machine, the removable cutting knife can work with the module for installing decorative elements 1 both simultaneously (in parallel) and separately (separately).

There is a known method of decorating a canvas of stretch ceilings, which consists in choosing a pattern, cutting a canvas of stretch ceilings and processing it with a programmed machine, in the memory of which the figure is pre-recorded in digital form, and the subsequent installation of the cut and processed canvas (see the description of the invention to patent " 2621232, MPK E04B 9/00, publ. 03.02.2017).

In the known method, the processing of the fabric of the stretch ceilings consists in cutting out patterns with a cutting tool of a machine tool equipped with program control. The drawing is preliminarily created using computer programs. A polymer film is used as a canvas for stretch ceilings. To decorate a stretch ceiling, a polymer film of different colors and textures is used, which complicates the process of decorating and increases the production time of the stretch ceiling.

In addition, stretch ceilings obtained by a known method have a low artistic and aesthetic quality.

The technical problem and result of the proposed device is to simplify the process of fastening decorative elements to the canvas of stretch ceilings, to increase the reliability of fastening and to reduce the labor intensity of the manufacture of stretch ceilings.

The technical result is achieved by the fact that the method of attaching a decorative element to a stretch ceiling fabric consists in cutting the fabric of stretch ceilings and processing it on a programmable machine, in the memory of which a digital pattern is pre-recorded, previously created using computer programs, and the subsequent installation of the cut and the processed fabric, while it additionally involves the use of the installation for attaching decorative elements according to claim 9, when decorating the fabric of stretch ceilings with decorative elements, which are pre-made with a threaded element for fastening made of a conical shape, and the decorative elements are screwed into the holes with a threaded element, which are preliminarily performed in the decorated canvas, according to a pre-selected pattern. Fabric or PVC is used as a canvas for stretch ceilings.

The proposed method is implemented in the following way.

First, the customer chooses a drawing, then on a machine with program control, in the memory of which the drawing is preliminarily recorded in digital form, cutting and processing of a PVC or fabric cloth is carried out, the thickness of the decorated surface of the cloth is 0.5-1.5 mm.

The processing of the canvas is carried out according to a pattern previously created using computer programs. Moreover, the processing of the canvas is carried out both with the fastening of decorative elements 1 around the cut patterns, and without cutting out the pattern, namely, by fastening the decorative elements 1 according to the pattern. Moreover, the fastening is carried out by screwing the decorative elements 1 with the threaded element 3 into the previously made through holes in the stretched decorative fabric 6 (the hole is not shown in the drawing).

The hole can be oval, round, or slot-shaped (elongated rectangle with rounded corners). The most reliable is an oval hole. Screwing decorative elements 1 into a round or slot-like hole can cause a tear (rupture) of the canvas along the contour of the hole when screwing in, which is not permissible, since the tear can lengthen and go beyond the base of decorative elements 1 during the operation of the stretch ceiling.

After decorating the surface of the web, the web is installed.
