Description

The invention relates to bedding, in particular to the design of a blanket for domestic use, made with increased heat retention and the properties of insulating the covered human body from heat and moisture (thermal stabilization in the sub-cover volume).

It is known a blanket containing a rectangular case in plan, in the central part of which a zone is formed that repeats the contour of the human body, divided into separate chambers arranged transversely oriented and filled with filler, while this zone and individual chambers in it are formed by joining the seams of the upper and lower paintings case to each other (DE No. 4091275, A47G 9/02, publ. 12.10.1995).

A feature of this blanket is that the contour of the zone repeating the contour of the human body is formed from the condition of repetition of the anatomical structure of the human body. In this regard, in the area of the proposed location of the shoulders of a person, this contour has wide transversely developed chambers (sections), and in the area of the legs - narrow, and in the area of the hips - widened with respect to the section for covering the legs. The rest of the blanket around the perimeter is stitched with a large number of linear seams. The disadvantage of this blanket is that it is not sufficiently designed in terms of taking into account the position of the sleeping person and his movements in a dream or in the event of uncomfortable sensations (feeling cold, chills). The lack of elaboration is due to the fact that in the blanket not only the area that follows the contour of the human body is divided into separate chambers, but the perimeter of the blanket is also divided into sections by linear seams. As a result, in the blanket, the zone repeating the contour of the human body is made with the same thermal stabilization parameters as the peripheral zone. That is, the entire blanket is one common zone with the same or almost the same thermal stabilization, which in principle characterizes the blanket as ordinary, for example, a quilted or full of fluff. The allocation of a zone that repeats the contour of the human body as a zone with a special regime of heat retention, with this design, loses its meaning and becomes an element of decor. If in this zone the amount of filler is increased compared to the amount of filler in the peripheral zone, then there will naturally be some difference in the thermal stabilization mode, but the need for such a slight difference is not confirmed by the need of the person covered with this blanket.

The present invention is directed to solving the technical problem of forming a blanket differentiated by the degree of thermal stabilization, in which the central zone, which repeats the contour of the human body, meets the needs of a healthy person in heat, and the peripheral zone is a zone of a temperature-contrasting subcloak volume. The task is also set (in terms of the method) of eliminating the twisting of the marginal sections of the blanket due to filing with an inlay with a cord.

The technical result achieved in this case is to increase comfort and ease of use with the exception of clumping of the filler and bending of the marginal sections of the blanket.

The specified technical result for the first embodiment is achieved by the fact that the blanket containing a rectangular cover in plan, in the central part of which a zone is formed that repeats the contour of the human body, divided into separate chambers arranged transversely oriented and filled with filler, while this zone and individual the chambers in it are formed by joining the seams of the upper and lower canvases of the cover to each other, the filler is fluff, oppositely located in the indicated zone on different sides of the cover, the outermost individual chambers are formed by arcuate seams, the convexities of which are directed towards each other, along the perimeter of the blanket there is a seam for connecting the upper and lower paintings of the cover at a distance from the edge, formed on three sides in straight lines, and in the area of the head and top the body with an arcuate line convex towards the specified zone, the upper and lower canvases of the cover are interconnected by linear seams emanating from the corners in the area of the legs in the direction of the zone, rep the range of this circuit is the human body.

The specified technical result for the second embodiment is achieved by the fact that the blanket containing a rectangular case in plan, in the central part of which a zone is formed that repeats the contour of the human body, divided into separate chambers arranged transversely oriented and filled with filler, while this zone and individual the chambers in it are formed by joining the top and bottom sheets of the cover to each other, provided with a lining fabric attached to the upper cover of the cover, and as a e of the filler, at least for the area of the zone repeating the contour of the human body, a polyester layer was used, in the indicated zone the extreme individual chambers oppositely located on different sides of the cover are formed by arcuate seams, the convexities of which are directed towards each other, along the perimeter of the blanket a seam is made to connect the upper and the lower canvases of the cover at a distance from the edge, formed on three sides by straight lines, and in the area of the head and upper body in an arcuate line, convex in side well of the indicated zone, the upper and lower canvases of the cover being connected by linear seams, coming from the corners in the area of the legs in the direction of the area that follows the contour of the human body, while the cover in the area that follows the contour of the human body is quilted.

The indicated features for each embodiment are essential and interrelated with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present invention is illustrated by a specific example of execution, which, however, is not the only possible, but clearly demonstrates the possibility of achieving the desired technical result.

In the drawing - a blanket, top view.

According to recent studies, a short, but impeccable in terms of quality of sleep is much more beneficial than unnaturally long. Newborns should sleep 15-18 hours, infants - 11-13 hours, schoolchildren - 9-10 hours, twenty-year-olds - 7-9 hours, fifty-year-olds and older - 6-8 hours. Healthy sleep is only possible with maximum comfort. Human skin with 7 million pores works like lungs: it breathes and is released from toxic substances. Sweat glands work at night somewhat more intensively than during the day. While a person is sleeping, 0.5 to 1 liter of moisture is released from the surface of the skin. A third of it evaporates, and two-thirds are absorbed by bedding, a mattress and a bed. Sweat is 98% water, and 2% is sodium chloride, urea, fat and acid. It is very important that toxins released during skin respiration do not poison the skin again. Therefore, the breathability and hygroscopicity of the blanket is of great importance. The choice of bedding depends on the individual characteristics of the person. So, products for sleeping from down and feather are light, warm and comfortable, perfectly absorb moisture, maintain body temperature and create a pleasant feeling of peace and comfort. At the same time, they differ in large volume with minimal weight. In this regard, the present invention considers blankets, the design of which fully meets the requirements of a healthy sleep, that is, provides comfort while maintaining a predetermined amount of heat and air exchange.

According to the present invention, the blanket according to the first embodiment includes a cover 1 made of upper and lower canvases of a rectangular shape in plan (may have rounding at the corners), the canvases along the perimeter are fastened together by a seam. For a cover the fabric puderzhayushchy is used (GOST 29298-92). In the central part of the cover, it is formed by a closed seam connecting the specified cover sheets to each other, zone 2, repeating the contour of the human body (given the fact that this zone should cover the covered person and on the sides). This zone is divided into separate chambers 3 located transversely oriented and filled with a filler such as fluff or fluff.

Like this zone, individual chambers in this zone are formed by joining the seams 4 of the upper and lower paintings of the cover to each other.

In the zone that repeats the contour of the human body, the extreme individual chambers oppositely located on different sides of the cover are formed by arcuate seams, the bulges of which are directed towards each other. Since the chambers are filled with fluff, and the length in the transverse direction of the chambers is quite large, there is a danger of lumping or rolling down to one edge of the chamber, as is often the case with quilted down comforters. In this regard, the seams separating the chambers in the upper part of the blanket are made convex towards the lower part of the blanket, forming a chamber, in the plan view, dobiform. With this design, the fluff in the chambers will tend to move to the center of the chamber, where the volume is larger than along its edge sections. The same applies to the cameras at the bottom of the blanket. Practice has shown that when knocking down a duvet, fluff moves from the edge sections of the chambers to the center, which makes it possible to evenly distribute fluff over the chamber in case the latter nevertheless strayed.

In the present invention, a waterfowl fluff filler is used. The main property of fluff is its thermal insulation ability.

The composition of the filler:

- "Extra" - a mixture of 97% fluff and 3% feather waterfowl.

- "Prima" - a mixture of 60% fluff and 40% feather waterfowl.

A seam 5 is made around the perimeter of the blanket to connect the upper and lower canvases of the cover at a distance from the edge, formed on three sides by straight lines, and in the area where the head and upper body are placed, an arcuate line convex towards the specified zone. Since the peripheral part of the blanket is a fairly developed surface, to prevent deformation, the cover canvases are fastened in straight lines with a seam on three sides of the blanket (in the legs and sides). This peripheral zone may inside carry an extra layer that is sewn. And in the area where the person’s shoulders or head is placed, the seam is concave towards the area of the person’s contour in order to soften this part of the blanket, since in practice this part of the blanket is crumpled by a person to make placement comfortable on the neck.

The upper and lower canvases of the cover are interconnected by linear seams 6, emanating from the corners in the area of the legs in the direction of the area that follows the contour of the human body. These seams add rigidity to the blanket in the area of the legs, since when covering it precisely due to the movement of the legs into the blanket, the latter is adjusted to a comfortable position.

The blanket according to the first embodiment allows to provide the following consumer properties:

- unique heat-shielding properties;

- optimal temperature conditions;

- high hygroscopicity: absorb and evaporate moisture;

- breathability: allow the body to breathe;

- low specific gravity and large volume;

- soft elasticity of products.

According to the second embodiment, the blanket basically repeats the design of the blanket according to the first embodiment in terms of the execution of the cover, the presence of a lining layer and the formation of a zone that repeats the contour of the human body, as well as fixing seams, but has distinctive features in the design.

A feature of this blanket is that it is made with a lining fabric sewn to the upper fabric of the cover as a second layer of the upper fabric.

The material is "thermoregulating." This material is patented by an American company, which was the first to start the development of thermal control technology. The main feature is that it maintains a constant body temperature, regardless of the degree of motor activity and external temperature. The material includes a huge number of microcapsules filled with a substance that can quickly transfer from a solid state to a liquid state and vice versa, and thus accumulate or give off heat. When the temperature rises, excess heat absorbs into itself, preventing the body from overheating, while lowering the temperature, heat is given back, preventing overcooling. Thus, the material maintains a constant temperature balance inside the garment. The excess heat of your body is absorbed by the tissue capsules, preventing overheating. Heat is evenly distributed throughout the layer, eliminating the occurrence of local overheating or supercooling zones. The stored heat is released when the body temperature decreases, maintaining optimal thermal balance. The material is hypoallergenic, so it is suitable for people prone to allergies.

The processes of absorption and regulation of thermal energy in a material are based on the principles of thermodynamics. Heating causes the molecules to accelerate. In cold environments, on the other hand, molecular motion is slow. Imagine the process of boiling water. Fast “hot” molecules collide with slow “cold” ones like billiard balls; energy is transferred from hotter to colder molecules. Thus, energy is transferred from a warmer environment to a colder one.

This material is not the only one that can be used as the material of the second layer of the upper canvas. You can use the material, the feature of which is the presence of microscopic granules-spheres that absorb heat when it’s hot, and give off when it’s cold. You can use a polypropylene fabric, its knitting provides breathable properties and maintains a microclimate. Both materials have approximately the same properties as a proprietary product.

Equipping the blanket with a lining cloth or its analogs sewn to the upper cloth of the cover provides stable thermal conditions inside the blanket, and, as a result, in the duvet cover. On the other hand, the upper web with an additional layer performs the function of a boundary layer on which there is a collision of air temperature flows of different temperature, especially from the side of the external environment. An additional layer, without interfering with the cooling of the upper sheet of the cover, eliminates the transfer of cooling from it inside the chambers to the filler.

Another difference is that, as a filler, at least for the area of the zone repeating the contour of the human body, a polyester layer was used (Estrella silicone polyester layer, 200-400 g / m ² , and a cover in the zone repeating the human body contour quilted stitch.

Hollow polyester siliconized fiber is widely used as a filler. This fiber perfectly retains heat (when examining a material under a microscope, you can see its distinctive feature - each fiber has a hollow shape). Products with this filler perfectly retain heat, hold volume, while possessing softness and elasticity, allow the skin to "breathe", creating maximum comfort and coziness. In addition, it should be noted that this filler is environmentally friendly, odorless, hygienic and does not cause allergies.

This variation of performance has the same features for stabilizing the thermal conditions in the duvet cover, but it is designed not to use a fluff type filler, but to use a plastic filler that is inserted in a layer under the lining layer and quilted with a stitch.

The blanket according to the second embodiment allows to provide the following consumer properties:

- high thermal insulation ability;

- hypoallergenicity: does not cause allergic reactions;

- breathability: provides air circulation through the filler;

- the possibility of washing at a water temperature of no higher than 40 ° (products quickly dry and restore volume and shape after washing).

The use of polyester fiber gives the blanket additional properties:

- comfort: the product takes on an individual body shape;

- increased elasticity: greater resistance to crushing and stalling.

The blankets for both versions are characterized by variable differentiated thermal stability in the central and peripheral zones, which allows the user to adjust the temperature of the duvet cover and body temperature using various sections of the blanket.

The manufacture of a blanket with a filler in the form of fluff is as follows.

1. Lay the canvas cover on the coating table with the wrong side up. Lay a pattern on top of the canvas and use it to cut the slices along the 4 sides and mark out the stitching lines of the camera steps (forming the contour of the zone repeating the human body).

2. On one canvas, sew down the nips along the marking lines (two curly lines and three straight lines), starting with the straight line, then the curly line, reducing the line to “no”, go to the straight line, starting to line it from 1 mm and then 3 mm, then curly again and then straight. At the beginning and at the end of the line, put a stitch (no more than 1 cm).

3. On the second sheet, stitch the tucks in the same way as the first sheet, while simultaneously securing the chambersteps along the marking. Stitch chambersteps along the marking located perpendicular to the pointed stitches, four straight lines, in a continuous line. At the beginning and at the end of the line, put a tack.

4. To put the first canvas with sharpened tucks on the second with chambersteps, begin to connect the canvases in series along chambersteps and marking lines. Start stitching to the tucks of the chamberstep of the second canvas, then go to the long one and stitch the chamberstep with continuous stitching, go to the short chambersteps and get to the last ones.

5. To prepare a slanting inlay from fabric of a cover with a cord, having fixed a cord in an inlay. Bend the neckline in half, put the cord to the bend and lay the fastening line. Connect the canvas, laying between them the prepared edging, double stitching, leaving holes for marking above the long chambersteps.

6. Fill the cover with feather fluff and fill the holes.

The manufacture of blankets with filler in the form of a layer of polyester silicone is as follows.

1. Apply the canvas with the front side on the wrong side of the canvas from the main fabric, and from above lay the second canvas from the main fabric with the front side inward.

2. The canvases are joined together along the canvas from the main fabric, while simultaneously laying a separate edging between the canvases. First of all, the edging is sharpened to one of the transverse sides of the edging on the front side, combining the cut of the canvas and the earned edge of the edging.

3. The second fabric is applied facing the first one, combining the sections and joining the canvas together with a seam seam 1.2-1.5 cm wide. Stitch along the transverse side by 29 cm with a fastener at the beginning of the stitch and further along the perimeter of the cover and end along the transverse side 29 cm, leaving a 90 cm hole. The frequency of stitches is 5 cm with a 15-20 stitch machine.

4. Lay the cover on the back table with the wrong side. On top of the cover lay the polyester layer, evenly distributing it over the entire area of the cover.

5. Roll the cover with the filler along the length and turn it on the front side, then straighten the filler in the corners and the entire area of the cover.

6. Tuck the blanket into the frame so that the top is the canvas cover, duplicated with the canvas. The stitch pattern should begin on the transverse side of the cover opposite the neck. Quilt on a single-needle machine.

7. Then, the open edge of the blanket is stitched on the front side, bending the trim edges inward by 1.2-1.5 cm at a distance of 0.2-0.3 cm from the edge. At the beginning and at the end of the line, the stitches are set.

The present invention is industrially applicable, as it can be manufactured using known technologies used in the manufacture of quilted or pouched blankets.
