Description

The proposed solution relates to the field of light industry and can be used in all areas where blankets are used, in particular at home, in medical institutions, on tourist trips when used in tents and outdoors, and other areas.

The various gradations of warmth of blankets used in everyday life are widely known. Thus, blankets are divided into very warm, warm and cool and differ in the degree of heat retention and the type of filler. From a physical point of view, the main difference between them is the level of their thermal conductivity. It is assumed that, depending on the season and the temperature in the room, the consumer will use a blanket of one or another degree of warmth that meets his needs. At the same time, it is obvious that regardless of the season, even during one night, the temperature in the room can change significantly, for example, due to the cooling of the room in the case of an open window and other factors, not to mention field conditions, where the temperature can fluctuate significantly.

In this regard, the purpose of the proposed utility model is to improve known blanket designs.

The patent RU 2316244 C2, 10.02.2008, can be adopted as a prototype, which discloses a combined duvet cover with a blanket, made from one piece of fabric, on top of which a blanket is placed, having fixing elements sewn along the entire perimeter, which are combined with the fixing elements sewn to the blanket, the duvet cover is provided with fixing elements sewn on one side in the corners and along all sides of the perimeter, made from sections of the first part of the contact tape, the second part of which is sewn to the blanket in the corners and along its entire perimeter on one side and on the opposite side of the blanket, with the opposite side having an indent from its edges along the width of the blanket.

A significant drawback of the known solution is that the blanket has only one thermal zone, i.e. the blanket is made of a material with the same thermal conductivity, which does not ensure the creation of a thermal balance in combined blankets with the provision of insulation of the lower extremities, which have reduced thermal performance.

The basis of this utility model is the task of refining the design of a two-zone combined blanket, eliminating the above-mentioned shortcomings of the closest analogue.

The technical result is the creation of a two-zone combined blanket with two thermal zones to create a thermal balance with the provision of insulation of the lower extremities, which have reduced thermal performance.

This technical result is achieved by the fact that the two-zone combined blanket includes

the bottom panel is rectangular in shape,

an upper web made of an upper zone and a lower zone, where the lower web and the upper web are connected along the short side by means of a detachable connection,

wherein the lower zone of the upper web is designed in such a way that it provides reduced thermal conductivity, and the upper zone and the lower zone are connected by means of a connecting seam.

The lower zone has a thicker layer of fabric.

The lower zone is made of a denser material with lower thermal conductivity.

The connecting seam and detachable joint are made in the form of a zipper.

The connecting seam on the outside of the upper panel is closed with a flap, fixed along the entire width of the upper zone and overlapping the entire width in the lower zone.

Further, the proposed utility model will be examined in detail taking into account the illustration, where Fig. 1 shows a general view of a two-zone combination blanket in section, lying on a person, and Fig. 2 shows a top view of a two-zone combination blanket on which pos.:

1 - lower canvas;

2 - top canvas;

3 - upper zone;

4 - lower zone;

5 - valve;

6 - detachable connection;

7 - connecting seam.

First, it should be explained that one of the physiological values of the body, which reflects the state of its thermal balance, is body temperature. Conventionally, two temperature zones are distinguished in the human body - the core (internal) and the shell (external). The shell is a superficially located structure, namely the skin and subcutaneous tissue. The core is the internal organs and heat flows. The shell temperature is always lower than the core temperature and is not the same in different parts of the body, which is due to the difference in their blood supply, the thickness of the subcutaneous tissue. The parts of the body that have a higher shell temperature relative to other parts are the head and the trunk. The shell of the upper and lower extremities of the human body has a longitudinal temperature gradient, as a result of which the shell temperature of the upper and lower extremities of the body is lowest in their distal parts.

Next, it is necessary to explain that thermal conductivity is the molecular transfer of heat caused by the temperature difference. The lower the thermal conductivity, the less heat loss.

The proposed solution discloses a two-zone combined blanket, which is formed as a single sheet. It should be emphasized that the solution is aimed at improving precisely combined blankets, completely ready for a sleeping place, where there is a lower sheet (sheet) and an upper sheet (a blanket for covering). In the context of this application, the upper 1 and lower 2 sheets are understood as both a single-layer fabric sheet and several layers forming a sheet, for example, two outer layers with a filler-insulator between them.

The lower sheet 1 has a rectangular shape, slightly larger than the dimensions of a person in length and width. The lower sheet 1 can perform both the function of a sheet in the proposed two-zone combined blanket, and the function of a mattress, if the lower sheet is made of sufficient thickness and/or from several layers.

The lower web 1 and the upper web 2 are connected along the short side (bottom) by means of a detachable connection 6. For example, a zipper can be used as a detachable connection 6, where one side of the zipper is attached to the lower web 1, and the opposite side to the upper web 2. Also, as a detachable connection, it is possible to use Velcro, buttons, a push-button connection and other detachable connections that provide a single web when using a two-zone combined blanket and detachment of the lower web 1, for example, for washing or replacement with a lower web with different dimensions or characteristics, for example, in terms of thermal conductivity.

The upper web 2 is made of the upper zone 3 and the lower zone 4.

The upper zone 3 extends across the entire width of the upper sheet 2 from the top to approximately the middle of the blanket, occupying 40-60% of the area. The upper zone 3 covers mainly the torso, i.e. the area of the body with greater heat transfer and heat production, as explained above, and does not require increased insulation, and also eliminates excessive overheating of the torso, increased sweating and other negative factors.

The lower zone 4 of the upper sheet 2 extends across the entire width of the sheet from the bottom to approximately the middle of the blanket, occupying 40-60% of the area. The lower zone 4 covers the legs, i.e. the area of the body with lower heat transfer and heat production, as explained above.

The top fabric 2 can be made, for example, from wool, teak and other materials, or have several layers, for example, an inner and outer layer of satin with a filler between them made of down, synthetic padding, etc.

The lower zone 4 of the upper web 2 is made in such a way that it provides reduced thermal conductivity, for example, due to the fact that the lower zone has a thicker web layer. For example, the height of the web layer in the upper zone 3 is 4 cm and is made of synthetic fluff, and the height of the web layer in the lower zone 4 is 7 cm and is made of the same synthetic fluff.

Also, providing reduced thermal conductivity of the lower zone 4 can be ensured by making the fabric of the lower zone 4 from a denser material with lower thermal conductivity. For example, make the fabric of the lower zone 4 from swan's down with a density of 340 g/ ^m2 , and the fabric of the upper zone 1 from cotton.

This design provides reduced thermal conductivity in this lower zone 4, ensuring faster warming of the feet and the temperature background and the creation of a thermal balance in the proposed two-zone combined blanket.

The upper zone 3 and the lower zone 4, forming the fabric, are connected by means of a connecting seam 7. The connecting seam 7 can be either solid, formed, for example, by stitching the ends of the upper zone 3 and the lower zone 4 together with threads. Or, the connecting seam 7 can be made in the form of a quick-release connection, formed, for example, by a zipper or buttons, connecting the upper zone 3 and the lower zone 4 together.

It is necessary to clarify that a quick-release connection is an element for connecting different parts that allows for their quick connection/disconnection; in the context of this application, this is Velcro, a push-button connection, a zipper, etc.

It is preferable that the connecting seam 7 on the outside of the blanket is closed by a flap 5, fixed along the entire width of the upper zone 3 and overlapping along the entire width in the lower zone 4, to reduce heat loss through this connecting seam 7. This connecting seam 7 reduces the escape of air through possible openings/gaps formed when connecting the upper zone 3 and the lower zone 4 to each other, which also additionally contributes to the creation of a two-zone combined blanket with two thermal zones to create a thermal balance with the provision of insulation of the lower limbs.

The connecting seam 7, in addition to creating a thermal balance with the insulation of the lower limbs, by connecting the upper zone 3 and the lower zone 4 together, also additionally allows, if necessary, to disconnect the upper zone 3 and the lower zone 4, for example, to wash one of the parts or replace one of the parts with a part with different thermal parameters, without changing the entire blanket, to create a thermal balance for a specific person or a specific situation.

The device works as follows.

The user places the blanket with the bottom sheet 1 on a flat surface, such as a bed, tent floor, mattress, etc.

The user lies down on the lower sheet 1 and covers himself with the upper sheet 2. The user covers his torso with the upper zone 3 and his legs with the lower zone 4, which are connected by means of a connecting seam 7. The lower zone 4 provides reduced thermal conductivity.

The presence of the lower zone 4 provides reduced thermal conductivity of the blanket in this lower zone 4 and reduces heat loss from the leg area. In turn, the upper zone 3 has greater thermal conductivity, thereby providing greater thermal conductivity from the human body to the environment, but the body produces significantly more heat than the legs, which is lost to a greater extent through the upper zone 3, providing thermal balance.

In the case of the product being manufactured, in particular, for use on campaigns by military personnel in conditions unprepared for sleeping (under a canopy, in a tent, in a dugout, etc.), the lower sheet 1 is made of a material with low thermal conductivity, thereby the lower sheet 1 also participates in thermoregulation, reducing the flow of cold from below, to create a thermal balance.

The structural design of a two-zone combined blanket in the form of a single sheet formed by a lower sheet 1 and an upper sheet 2, connected along the short side by means of a detachable joint 6, where the upper sheet 2 includes an upper zone 3 and a lower zone 4, connected by a connecting seam 7, as well as the design of the lower zone 4 with reduced thermal conductivity, ensures a balance between the transfer of heat from the human body to the external environment and its thermal performance.
