Description

The utility model relates to the construction of a covering device made of transparent flexible film, designed to protect architectural openings and skylights, and can also be used instead of glass materials for protecting windows, doors and other openings of various premises (verandas, attic, gazebos, terraces, balconies ).

Known is a system for protecting buildings made of PVC film, which is placed in roller boxes (1) made of corrosion-resistant materials and, if necessary, is attached from the outside to the building structure using mounting and overhead profiles (4, 5). The joints obtained are made watertight with rubber sealing elements. The foundation walls are protected by permanently attached PVC plates. The invention is intended to protect buildings from water and dirt penetration [1].

Known heat-insulating, transparent building element for closing architectural openings, which can be used for warehouses, greenhouses and other similar places. The building element contains a transparent PVC film and a wooden, plastic or metal frame, which can be square, rectangular, round or curved, i.e. non-flat. The PVC sheet is stretched over the frame from both sides. The frame can be reinforced with spacers. Plastic sheets are transparent, translucent or opaque. The building element can be used as components in the form of wall, door and window elements and roof elements. The use of polyethylene film provides good heat-resistant and insulating, that is, energy-saving performance. [2]

It is widely known in the art to use polyvinyl chloride (PVC) or polyurethane for the manufacture of protective closures. Recently, polyvinyl chloride shielding devices have gained wide popularity. Such structures have an excellent appearance, protect from wind, dust, rain, snow, noise and insects, they make the space more comfortable, allowing you to use such a room in any weather and in almost any season.

Such devices are characterized by the use of a transparent or tinted film based on PVC or polyurethane, containing a strong opaque edging around the perimeter and metal or plastic fittings (eyelets, parts of straps) intended for fastening. Traditionally “OXFORD” or “Velfi” fabrics are used as edging. The product is, as a rule, a rectangle with an edging, stretched by means of fittings on the openings, thus forming a one-piece insulation. The shape may be different and depends on the opening. [3, 4].

As the closest analogue, the applicant's closing device was chosen, which is characterized by its execution of a transparent PVC film, contains an edging made of PVC awning fabric and metal fittings [5]. The edging is intended not only to give the soft window a design solution, but to a greater extent to stabilize the PVC canvas and strengthen the edge of the film for the installation of accessories. The disadvantage of the known solution is that the fabrics used for edging are quickly worn out, under the influence of the sun, precipitation, wind, they discolor, lose their original appearance, and creases form at the place of the fold, which requires replacement of the closing device as a whole. Given the growing consumer demand for these products, competition among manufacturers is also increasing. The problem solved by the utility model is to increase the service life of the closing device in order not to change the soft windows every season, but to use them for a long time in their original aesthetic and functional quality, which increases the competitive advantages of the product.

To solve this problem, it is proposed that the edging be made of artificial leather, also often referred to in sources as "eco-leather". Artificial leather is a material that consists of two layers. A woven fabric acts as a base, and on top is a layer of polymer painted in the desired color. The physical and mechanical parameters of artificial leather are known from publicly available sources. It is frost-resistant, successfully resists the effects of low temperatures and does not become brittle in frost, has increased wear resistance, is durable, tear-resistant and insensitive to direct sunlight, has shape stability (does not stretch, does not wipe at the folds), elastic, undemanding in leaving. It would seem that such a material is ideal for solving the task, but the problem is that when using artificial leather for edging, difficulties arise in the manufacture of a product due to the lack of a permanent stable state - the stability of the film and edging. The film stabilization in such products is lower than with the edging of OXFORD, Velfi or other fabrics. In this regard, the solution to the problem is possible only when solving the issue of stabilizing the product when using artificial leather.

When solving this problem, a technical result is achieved, which consists in increasing the shelf life of the closing device in its original state.

The problem is solved, and the technical result is achieved by the fact that in the closing device, which is a sheet of flexible film with edging and fittings, the new is the execution of an edging made of artificial leather, while the film sheet is placed inside the edging on its width, the fittings are installed with simultaneous gripping layers of edging and canvas, these layers are welded together. The distance between the fittings is 26-37 cm. Polyvinyl chloride or polyurethane is used as a film.

The essence of the utility model is illustrated by illustrative materials, where

in fig. 1 is a general view of a closure for architectural openings;

in fig. 2 and 3 show the formation of three layers of an artificial leather and film product and the arrangement of the film web inside;

in fig. 4 - shows the place of perforation of the product and installation of fittings;

in fig. 5 shows an embodiment of a product with a zipper fastener.

Next, referring to FIG. 1 describes the proposed utility model. The closing device contains a flexible sheet 1, an edging 2 and accessories 3.

Cloth 1 is a polyvinyl chloride or polyurethane film with a thickness ranging from 500 to 700 microns, depending on needs. Film 1 has high technical characteristics. These include a high level of strength and ductility, durability, resistance to moisture, UV radiation, temperature extremes. The appearance of mold and mildew is excluded on the surface of the material. The material is fireproof. Such a canvas serves for a long time without requiring replacement.

Edging 2, in contrast to the closest analogue, is made of artificial leather. The edging is used in order to strengthen the installation site of the fittings and stabilize the sheet 1 made of film.

Fittings 3 are intended for fastening the closing device to the frame base. To do this, use swivel brackets - the simplest method using spring brackets and eyelets; staples and straps - an inexpensive method of fastening with adjustable buckles; sliding mechanism with frame roller system. Fasteners are mounted either along the perimeter of the frame, or on the sides and / or at the bottom of the frame; in this case, eyelets for mounting windows are fixed in the upper part by means of self-tapping screws.

A distinctive feature of the proposed solution is the use of artificial leather as edging, which due to its characteristics has advantages over other materials. However, the use of artificial leather, as mentioned above, entails another problem associated with low stability.

Stabilization refers to the mechanical strengthening of the edge of the product. Stabilization is necessary to eliminate the negative factors associated with the difference in the properties of materials (PVC film and artificial leather), namely, different values of compression and elongation of materials at the same temperature. Stabilization of the film in the product is achieved by edging and installing fittings. In addition, the overall strength and uniformity of the product is thus achieved. In this regard, the capture during the installation of the fittings of three layers, including the edging made of artificial leather 2 and the sheet of the film 1, as well as the installation of the fittings with a step of 26-37 cm are essential.

FIG. 2, 3 it is shown that the edging 2 bends around the web of the film 1 with the formation of three layers: the first layer is artificial leather, the second is the film web, and the third is artificial leather. In contrast to the known solutions, it is important to locate the canvas 1 (second, middle layer) in the edging 2. It should completely fit the width of the edging (Figure 3) or no more than 0.5 mm not reach the fold of the edging (Fig. 2). This arrangement of the web 1 in the edging 2 allows you to install the fittings 3 with the simultaneous capture of all three layers and thus ensure the stability of the fixing of the fittings and the stability of the web. When using edging made of other materials, manufacturers install fittings, capturing only two layers from the edging, the inner layer of the film does not form, it is enough that the canvas is slightly captured by the edging, but not by the fittings.

The fittings are installed as follows. One of the fastener parts, for example, a grommet, is installed in the welded seam with the required step. The eyelet sleeve is inserted into the hole of the three-layer blank of the product on one side, and on the other, a washer is put on it and fixed by expanding the sleeve. Mounts other than eyelets are installed in a similar manner.

Another significant feature is the distance between the fittings. If in known analogs, the fittings are installed with a step of at least 38-45 cm, then in the proposed solution within the range of no more than 26-37 cm.It is obvious to the specialist that the more often the fittings are installed, the more stability it provides, which is a prerequisite when using edging made of artificial leather.

Depending on the width and height of the product, the required number of fittings and the step between them are calculated with rounding of the results obtained. Moreover, in height, the installation of the fittings should be symmetrical on products located nearby. The calculation is carried out as follows. For example, the width of the product is b = 140 cm, the experimentally established coefficient is accepted as k = 30, (the coefficient when using edging for other materials is 40). The number of eyelets (f) is calculated using the formula f = b / k or 140/30 = 4.66666666667, that is, you should use 5 eyelets, the step will be 28 cm (s = b / f or 140/5 = 28). FIG. 1 shows that the distance l between the fittings is measured from the center of the eyelet. As established experimentally, the more frequent installation of eyelets is excessive, and the installation of fittings with a step of more than 37 cm does not provide the proper stability of the edging.

The developers guarantee an increase in the service life of the device up to 10-12 years, subject to the rules and operating conditions, which triples the shelf life of the closing device without the need to replace it due to edging cracks and damage.

The closing device is made as follows. Cut the blank edging 2 made of artificial leather with a margin of 10 cm in length, width, for example, 5, 8, or 10 cm. Cut out PVC film 1 for the given dimensions of the architectural opening. The width of the film roll, as a rule, is 140 cm. If it is necessary to manufacture a product to close large openings, it is allowed to weld two or more canvases together or create a non-standard shape. The film is fixed on the cutting floor with staples using a stapler without folds, slightly pulling the material. Marking is made on the film for subsequent welding of the edging. With an edging 2 made of artificial leather, they bend around the film 1, capturing it so as to ensure its full position inside the edging (Figs. 2, 3). Then the fittings are installed with the capture of all three layers. This is done to stabilize the product more. PVC film is not stable and has temperature shrinkage. If the fittings do not grip the fabric inside the edging, then two layers of artificial leather edging will not "hold" the fittings, it will fall out. The edging will be rough if the canvas is placed in the edging with a bend in more layers, which, moreover, will not allow the installation of accessories. Next, the diagonals of the product are checked, the tolerance should be no more than 0.5 cm, otherwise the product will not stand on the opening. For convenience, they are fixed with staples with a stapler on the cutting floor according to the dimensions with pretension, but not overtightening. Then three layers of the product are welded. Welding is carried out with a semiautomatic device for hot air welding of technical PVC fabrics. When welding edging and film, the beginning and end of the seam are protected from thermal deformation. For this, masking tape is glued to avoid burns on the material. After passing by the semiautomatic device on one side, the product is turned over and the welding process is repeated. Then the excess edging is cut off, leaving the material for the collar. Fold over the edging is done to ensure the tightness of the seam, as well as the wear resistance of the material in the places where the weighting agent is inserted (“pocket”), as well as to preserve the neat appearance of the product during the operation of the product. The corners of the product require careful welding of layers, this is done with a handheld dryer for welding polymer materials at a temperature of 500-550 ° C. Stitching instead of welding layers of transparent film and artificial leather edging is not acceptable, since welding provides a more reliable adhesion of the layers of film and edging.

If desired, a zipper 4 is sewn in with the hem of the edging to ensure the strength of the fastening of the zipper to the edging, as well as to ensure an aesthetic appearance (see Fig. 5). Sewing of the edging with a zipper is allowed. For this, lavsan threads are used, which are resistant to temperature extremes, stretching, rupture, destruction from moisture and sunlight.
