Description

The utility model relates to fire fighting equipment, and more specifically, to a primary portable means for preventing the spread, localization and extinguishing of a fire by isolating it from ambient air oxygen, including large areas of fires of classes A and B, solid, liquid and oily materials , as well as for extinguishing objects such as cars, river transport, electrical equipment, burning clothes on people, and as a curtain during the evacuation of victims and carrying out fire, gas and electric welding works.

Known fire blanket containing heat-resistant fabric (Patent for utility model No. 43177 priority dated 09/18/2002, copyright holder CJSC "KOSMI-POZHSERVICE", RF).

This known bedspread has a simple construction made from a single piece of fabric material.

The disadvantage of this known fire blanket is its fragility and fragility due to instability to burn-through under the influence of high temperature and fire, due to the unprotected surface of its fabric material, as well as increased air permeability, which reduces the effectiveness of extinguishing fire. In addition, the use of this blanket, made from a single piece of material, is most suitable only for extinguishing fires on small flat surfaces, because To extinguish the fires of bulky objects, blankets of an increased area are required, ensuring their full coverage and requiring for their use a woven material of an increased width, which increases the cost of their production and the cost of finished products.

There are also known various fire blankets containing a heat-resistant fabric with a fire-retardant coating, one of which is disclosed in the patent for utility model No. 126945 priority dated 07.06.2012, the copyright holder of JSC "PyroKhimika" (RU).

This known blanket has a simple structure, made from a single piece of fabric material, and has increased fire extinguishing efficiency, reduced air permeability and increased resistance to burn-through under the influence of high temperature and fire due to the use of a flame retardant coating of fabric material.

The disadvantage of this known fire blanket, as well as the above, is the lack of mechanical strength, as well as the fact that its use is most suitable only for extinguishing fires on small flat surfaces, because To extinguish the fires of bulky objects, blankets of an increased area are required, which provide full coverage of the objects of ignition and require the use of a woven material of an increased width for their manufacture, which leads to an increase in the production costs of these blankets and their rise in price.

The closest to the proposed utility model in terms of the totality of features is a heat-resistant fire blanket, consisting of a non-combustible woven material with a fire-resistant adhesive coating and sewn from at least two of its segments (Patent for invention No. 2592792, priority from 01/30/2013, patent holder "BLH TECHNOLOGIES INC. "WITH A).

This blanket, which is closest to the claimed utility model, in comparison with the above-mentioned known fire blankets, has an increased resistance to burn-through.

The disadvantage of this bedspread, which is closest to the claimed utility model, is the laboriousness of its manufacture, due to the multilayer layers of woven fabric of the same size stacked on top of each other, sewn together along the perimeter, forming a semblance of a sandwich cloth, the strength of which is achieved by increasing its thickness. Thus, the formation of the thickness of the coverlet, and not the area of its surface, by the used pieces of woven material, does not provide the possibility of using this coverlet to extinguish the fires of bulky objects that require the manufacture of coverings of increased dimensions, providing full coverage of the objects of ignition, which leads to an increase in the production costs of these covers. and their rise in price.

The technical result of the claimed utility model consists in the possibility of manufacturing a fireproof cover of any size due to the formation by the surfaces of all of its stitched sections of woven material of the full surface of the cover, which has an increased mechanical tensile strength, provided by strong seams between its sections, which perceive breaking forces and distribute them among themselves, and also in the simplicity of its design, using woven material of any size for the manufacture without increasing production costs and the cost of the finished product.

The specified technical result is achieved in that a heat-resistant fire blanket consisting of a non-combustible woven material with a heat-resistant adhesive coating and sewn from at least two of its segments ... the entire surface of the bedspread and sewn together with connecting seams of the second class with sewing metallized thread along the parallel butted boundaries of these segments, moreover, the fire-retardant coating of non-combustible woven material is a solidified layer of a liquid-like mixture, dispersed over its surface during formation.

The production of a woven fabric in a fire blanket made of fibers and / or threads with a silicon dioxide content of at least 45% helps to increase its fire resistance.

The manufacture of a fire blanket with at least one fixed fold laid along its entire length or width perpendicular to the connecting seams, tying all the connecting seams between the pieces of material into a single frame, helps to increase its mechanical tensile strength during operation.

The application of a fire retardant adhesive coating on one of the surfaces of the woven material of the cover allows to reduce the cost of its manufacture by saving the consumption of the fire retardant coating.

The implementation of the rectangular bedspread provides manufacturability of its manufacture and ergonomics of use.

The production of a blanket with at least two handles for its opening, operation and folding speeds up the process of using the product in case of a fire, ensuring its ergonomics.

Execution of a blanket with holes reinforced with an eyelet around the perimeter of the product for threading heat-resistant flexible means through them, for example, ropes, cords, braids, cables used both to fix the blanket on surfaces that limit objects of fire, and as handles for opening the blanket, its operation and folding, increases the reliability of localization of objects of fire and provides ergonomic use of the bedspread.

The use of sewing metallized thread made with a core of steel wire, solid or braided, for sewing the pieces of woven material, increases the strength of the seams of the pieces of material being sewn and, as a consequence, the mechanical strength of the cover to break.

The proposed utility model is illustrated by drawings:

FIG. 1 - A heat-resistant fire blanket made of 2 pieces of woven material, sewn with a locking seam;

FIG. 2 - A-A Fig. one;

FIG. 3 - Heat-resistant fire-resistant blanket with a fold and a grommet along the edging seams, sewn with a connecting seam "sewing" from 3 pieces of woven material;

FIG. 7 - Metallized sewing thread with a braided steel wire core (section).

FIG. 8 - Table of joining seams of the second class (GOST 12807-2003) used for stitching pieces of woven material with a fire retardant coating.

A heat-resistant fire-resistant blanket of rectangular shape (Fig. 1) contains two sections 1 and 2 of silica woven material with one-sided fire-retardant adhesive silicone coating each, which is a solidified layer of a liquid-like mixture dispersed over the surface of the woven material, respectively 3 and 4 (Fig. 2), placed relative to each other with the possibility of forming their surfaces of the full surface of the bedspread and sewn together along the parallel butted boundaries of the material segments with a strong connecting seam "locks" 5 (Fig. 8) with the stitches of the metallized thread 6 (Fig. 6), as well as the edging seam 7 along the edges of the bedspread and handles-loop 8 made of a corsage tape (Fig. 1), the ends of which are sewn onto the edging seams 7 in the corners of the sewn fabric sections 1 and 2.

Shown in FIG. 3, 4 and 5, a heat-resistant fire blanket, in contrast to a blanket of two fabric pieces, contains three pieces of silica woven material 1, 2 and 3 with a double-sided fire-retardant adhesive polyurethane coating, each, 4, 5 and 6, respectively, sewn together with strong connecting seams of the second class "sewing" 7 and 8 (Fig. 8) with stitches of metallized thread 9 (Fig. 7), as well as an edging seam 10 (Fig. 3, 4 and 5) along the edges of the bedspread with holes 11, reinforced with eyelet 12, for threading through them heat-resistant flexible means (not shown), for example, ropes, cords, braids, cables used both to secure the cover on surfaces that limit objects of fire, and as handles for opening the cover, its operation and folding, and, in addition, , additionally contains a fold 13 reinforcing the cover (Figs. 3 and 5), laid perpendicular to the connecting seams 7 and 8.

The manufacture of a heat-resistant fire blanket is carried out as follows using known technological equipment.

For sewing the product, a roll of non-combustible woven fabric is purchased with a fire retardant adhesive coating, which is a solidified layer of a liquid-like mixture, dispersed over its surface during formation. For example, for the manufacture of a fire blanket measuring 600 cm × 800 cm, a roll of fiberglass with a double-sided silicone coating, 5700 cm long and 100 cm wide, is purchased, cutting it into 7 stitched sections.

Thus, before cutting the purchased canvas into pieces of the appropriate size, determined by the purpose of the cover, the sizes of the blanks of these fabric pieces are calculated, taking into account the consumption of material for the seams connecting them, for the edging of the product and folds, if any, and also determine the total number of sewn segments, which are sufficient to form a complete surface, covered with the surfaces of the segments. Then, the web of the acquired material is marked and cut into blanks of segments of the calculated size, after which one segment is sequentially sewn with another, forming the seams connecting them along the parallel-abutting boundaries of these segments. To ensure increased strength of the connection of pieces of woven material, seams of the second class are used (Fig. 8) and a fire-resistant strong metallized thread with a solid or braided steel wire core. After that, the fabric sections sewn together are processed along the contour with an edging seam.

A fireproof blanket of two sections 1 and 2 (Figs. 1 and 2) of woven material is made from a purchased silica cloth with a one-sided silicone fire retardant coating, cutting out of it pre-sized blanks of fabric sections 1 and 2 (Fig. 1 and Fig. 2) , with a silicone fire-retardant coating of surfaces, each, respectively, 3 and 4, taking into account the consumption of material for the seam connecting them "in the lock" 5 (Fig. 8) and the edging seam 7 along the edges of the bedspread. Then these fabric segments 1 and 2 are sewn together along their parallel butted borders, forming a seam 5 (Fig. 8) connecting them with the stitches of a metallized thread 6 (Fig. 5). After that, they begin to form the edging seams 7, and then cut the material under the loop handles 8 and sew their ends onto the corners of the stitched sections 1 and 2. The fire blanket is ready for use.

The manufacture of a fire blanket from three fabric sections 1, 2 and 3 (Figs. 3, 4 and 5) differs from the manufacture of a fire blanket from two sections by the production of sections of woven material with a double-sided heat-resistant adhesive coating and the formation of an additional strong connecting seam 8 with stitches of metallized thread 9, connecting the 2nd and 3rd sections of the woven material, as well as the manufacture of an edging seam 10 with holes 11, reinforced with an eyelet 12, and, in addition, the formation of an additional reinforcing folds 13, laid perpendicular to the connecting seams 7 and 8.

Thus, the created technical solution, due to the totality of its essential features reflected in the formula of the utility model, makes it possible to manufacture a fireproof cover of any size due to the formation by the surfaces of all of its sewn sections of woven material of the full surface of the cover, which has an increased mechanical tensile strength provided by strong seams between its segments that perceive breaking forces and distribute them among themselves, as well as in the simplicity of its design, which uses woven material of any size for manufacturing without increasing production costs and the cost of the finished product.

The claimed heat-resistant fire blanket has been tested and is ready for release.
