The utility model relates to gloves that can reliably protect the hands of its wearer in the maximum possible temperature conditions, including at very low temperatures and in strong wind conditions, and can also be used to heat the hands of personnel of special forces and services on duty or working outdoors at low ambient temperatures, as well as for builders, gas workers and oil workers working in the cold season.

The special conditions for serving personnel by special forces, especially in the winter cold season, impose stringent requirements on clothes, shoes, and on the whole equipment of personnel, primarily to ensure the necessary temperature conditions. It is especially important to ensure the preservation of heat in the area of the hands using heated systems with low weight and volume. For these purposes, various heat generation systems based on chemical, physico-chemical, electrical, mechanical and radiation methods are used.

A two-component system is known (patent RU 2489949, IPC A41D 19/00, published 08/20/2013), including a glove, in particular a sports glove having a finger part containing individual fingers and a mitt-shaped part attached to the back of the glove and made with the ability to pull over the finger part, having the shape of a mittens, in the initial position, placed in a pocket formed on the back of the glove, and the pocket is made on the specified side with the ability to be locked with a locking mechanism, on the back on the side of the glove is provided a covering means for the locking mechanism, and the mitt-shaped part on the inside of the glove reaches approximately to the base of the fingers and is fixed at its end located at the base of the fingers on the inside of the glove

This technical solution does not assume the possibility of working from small-sized power sources, which reduces the operational properties of the system.

The closest analogue of the claimed utility model is a glove (patent RU No. 100884 IPC A41D 19/00, 01/10/2011) containing a storage area for a portable heating pad, which is made inside the glove body and stores many portable heating pads for heating the portion of the fingertips of the hand, which is inserted into a glove case with a portable heating pad inside the storage area of the portable heating pad, the glove body comprising a base portion with an opening for inserting / removing a brush; the area covering the palm, which continuously extends the portion of the base with the hole and covers the palm and the back of the hand; the area covering the thumb, which continuously extends the overlapping area of the palm and overlaps the thumb of the hand; an area covering four fingers, which continuously extends a portion covering a palm, and covers four fingers of a hand, namely, an index finger, a middle finger, a ring finger and a little finger; a front end portion with a hole formed on a portion of an edge of a front end of a portion covering four fingers; and opening / closing means that open / close the front end portion with the hole; wherein the storage area of the portable heating pad has an opening for introducing a portable heating pad for inserting / removing the portable heating pad and is located on the four-finger covering portion at the location of the four-finger fingertips when these fingers are inserted, the portable heating pad insertion hole being located on the the front end with the opening of the four-finger covering portion, and the hole for introducing the portable heating pad is torn / closed along the portion of the front end with the hole by opening / closing means, and wherein the storage area of the portable heating pad has a first compartment and a second compartment that separately store two portable heating pads, the first compartment and the second compartment respectively being rotatable inside the area covering four fingers in the direction of the inner surface the side corresponding to the fingernails, and the inner surface of the side corresponding to the fingertips, and optionally provide spaces that allow you to enter Stock fingertips or between the first compartment and the inner surface side corresponding to the nails of fingers, portion covering the four fingers, or between the first compartment and the second compartment, or between the second compartment and the inner surface side corresponding to finger pad portion covering the four fingers.

A disadvantage of the known device is its low operational properties, as well as the low efficiency of using heating elements of a portable heating pad, which is the so-called replaceable portable heating pad, which uses iron powder, oxidized in air, placed in a bag of nonwoven fabric or paper, or the so-called a portable platinum catalytic heater in which gasoline vapors are made to slowly oxidize to generate heat using a catalytic the reaction of platinum, the device has low functional reliability during operation.

As a prototype, gloves with heating were selected (patent RU No. 72823, IPC 41D 19/00, published May 10, 2008) containing electric heating elements connected to the power source through a switching system and installed inside the area of the back of the fingers. The heating element of the index finger is located on the side of its bend, and the compartment for the index finger has a longitudinal incision with a detachable connection covering it. The electric heating elements are made in the form of flexible carbon fiber materials and are interconnected in parallel, and the power source is located in a special container formed on the outside on the back of the glove. In this case, the power source of the heating elements are plate-type electric batteries based on fluorocarbon-lithium-non-aqueous electrolyte, collected in a package of at least two pieces, and connected through a connector. A thermal relay is used as a switching element.

The disadvantage of this device is the exposure of the heating elements to mechanical damage during intensive operation and their fire hazard. The device does not provide uniform heating of the hands, and has low performance properties.

The known devices and the claimed utility model have the following essential features:

- performed function - heating using heating elements;

- the disadvantage of all known devices is the exposure of the heating elements to mechanical damage during intensive operation, their high fire hazard due to the material of the used heating elements, i.e. the elements used are not sufficiently durable, strong, subject to mechanical damage, etc.

The technical task of this utility model was to create a device for heating fingers and hands with high performance properties, such as hygiene, moisture resistance, heat resistance, strength, flexibility, designed to eliminate the above-mentioned disadvantages of the analogue.

The objective of the utility model is to create a device with an electric heating element made of Dacron filaments with resistive silver sputtering and located in a multilayer fabric consisting of layers: outer fabric, gasket and inner fabric. There is also an option in the form of three layers forming the Softshell material, i.e. including outer fabric, membrane and laminated non-woven fleece (Fleece) or jersey-type material that provides self-regulation of the temperature regime when it is used as a heating element in a given temperature range for a long time of operation.

The technical result of this utility model was the creation of a device for heating fingers and hands and maintaining the temperature inside the glove optionally at a level higher than the temperature of the external environment, increasing operational properties.

The technical result that can be obtained from the use of the utility model is to increase the reliability of a flexible heating element made of dacron threads with resistive silver sputtering and, as a result, increase the efficiency of the product as a whole.

This result is achieved by the fact that in the heating glove containing electric heating elements connected to the power source through the switching system and installed inside the multilayer fabric in the region of the back of the distal phalanx of the fingers, metacarpus and covering the wrist joint, made in the form of multilayer electrically heated mats made of lavsan silver resistive filaments to increase the efficiency of the heating elements in the composition of the heated mat included in the reflective layer made of aluminum film by vacuum deposition.

A thermal relay is used as a switching element.

Electric heating elements are located on the back of the heating gloves, thanks to which they effectively warm the distal phalanges of the fingers, metacarpus and wrist of the hand, while not restricting and restricting the movement of the fingers, and remain protected from possible damage.

The use of infrared heating helps to avoid electromagnetic radiation and has a positive bracing effect on the hands.

A small-sized power source is located in the bell of the glove in a special cavity located on the back of the glove that warms and does not interfere with the movement of the brush.

The use of electric heaters made of dacron filaments with a resistive silver coating, coaxially placed on the back of the heating glove, provides more efficient heating of the phalanges of the fingers, metacarpus and wrist joint, due to the larger contact surface with the heating elements and the presence of a reflective layer made of aluminum film using a vacuum spraying. The maximum temperature of a heating element made of lavsan threads with a resistive silver coating does not exceed 28 ... 34 ° C [Methodical recommendations MP 2.2.8.2127-06 “Hygienic requirements for thermal insulation of a set of personal protective equipment against cold in various climatic regions and methods for its assessment” ].

Electric heaters made of dacron threads with resistive silver sputtering have the following advantages:

- mechanical resistance and "superflexibility" - up to 150,000 bends per point, can be wrinkled, folded in any position, washed in a washing machine;

- products have successfully passed tests under extreme conditions (beyond the Arctic Circle);

- fast heating rate of the fiber - 1 ° C per second.

To regulate the heating of the glove heating the heating elements can be connected stepwise and in groups, depending on the ambient temperature, which significantly reduces the energy cost of heating the phalanx of the fingers, metacarpus and wrist joint to a predetermined temperature and allows maximum use of the thermal energy of electric heaters for heating.

Therefore, the claimed utility model meets the requirements of novelty.

The essence of the utility model is illustrated in the drawing of FIG. one.

Heating gloves contain heating elements (Fig. 1) located inside the multilayer tissue in the region of the back of the distal phalanx of the fingers, metacarpus and covering the wrist joint. The heating elements are made in the form of multilayer electrically heated mats, including a mat for heating the phalanx of fingers 1, a mat for heating the metacarpus 2 and a mat for heating of the wrist 3. The mat for heating the phalanx of fingers 1 and the mat for heating of the metacarpus 2 are located on the back of the signet, and the mat for heating the wrist 3 covers the back and the inside of the glove. An additional tightening element 4 is located on the wrist, preferably a flap valve, on the inside of which there is a Velcro Velcro. The Velcro mating element is located on the gait, as a result of which it is possible to grip the arm of the gait more tightly. On an additional tightening element 4 there is a presence (pressure) sensor 5 (shown conditionally), which enables the inclusion and operation of the device for heating the hand only when the glove is worn and tightly covering the hand.

Heating gloves are made of waterproof fabrics, a layer of heat-saving cotton and a reflective layer. The presence of a reflective layer made of aluminum film by vacuum deposition allows the use of infrared heating, which helps to avoid electromagnetic radiation and has a positive bracing effect on the hands, its main properties are softness, heating speed, resistance to wear, etc.

Heating elements made in the form of multilayer electrically heated mats 1, 2, 3 are interconnected in parallel and connected to a power source 6 using a current lead laid in the fabric channels of the gloves (not shown in Fig.), Connecting the heated mats 1, 2, 3 with a power source 6 (lithium-ion polymer battery), electronic components (not shown in FIG.), a presence (pressure) sensor 5, which ensures the functioning of the device for heating the hand only when it (the hand) is in the glove, ter Morel 7 (shown conditionally), designed to turn off the heating elements at temperatures above 34 ° C, to maintain the optimum temperature, comfortable for the user and turn on the heating elements at temperatures below 28 ° C.

The heating glove is made of three layers located in the following sequence (from top to bottom):

- the first layer - is designed for intensive heat transfer to the hand, and also provides hygiene, has a convenient 3D volumetric shape that takes into account the anatomy of the hands, the rather thin front part of the first layer of the multilayer glove does not hamper the movement of the fingers;

the second layer is a layer with placed heated mats 1, 2, 3, which can be connected in steps and in groups. The heating temperature depends on the density of the current flowing through the Dacron threads with resistive silver sputtering, which is directly related to the magnitude of the electric voltage supplied to specially formed current-carrying tires, previously applied to the material layer. By setting the magnitude of the supply voltage, it is possible to regulate the heat generation of mylar threads with resistive sputtering of silver, and hence its temperature;

the third layer is a reflective layer placed between the protective insulating layer and the outer fabric. The surface of the reflective layer is conjugated directly with the material of the insulating layer, for example, by applying a metal foil to the insulating layer by vacuum evaporation, an insulating fabric pad designed to reduce heat transfer from the heating element to the outer surface of the glove.

The properties of each of the layers together can provide the claimed technical result.

The inventive device for heating hands can be made in the form of an integral product.

The device for heating the hands is heated by the built-in lithium-ion polymer battery 6, which is pre-charged using a charger from the 220 V network (not shown in Fig. 1). After turning on, the heating glove does not work continuously, but only if necessary - this is important for proper blood circulation in the hands. The heating glove operation scheme is as follows: the thermostat 7 built into the electronic components of the second layer (shown conditionally) activates the heating system when the temperature of the hands decreases to 28 ° C and turns off heating when the temperature reaches 34 ° C, then the heated mats 1, 2, 3 gradually cool and give their heat to the phalanges of the fingers, metacarpus and wrist; if the temperature drops to 28 ° C, the heating cycle is repeated. This ensures comfortable and healthy temperature conditions for the hands, and also extends the operating time of the lithium-ion polymer battery 6. Heating is carried out in the back area of the distal phalanges of the fingers, metacarpus, and the wrist joint of the fingers is heated from the back and inside, which are usually freeze. To turn on the heating glove device, you need to put on gloves to fasten the tightening element 4, on which the presence (pressure) sensor 5 is located, which ensures the inclusion (functioning) of the device for heating the hands only with the glove on and tightly covering the hand, which will ensure the operation of the heating glove. When unfastening the tightening element 4, the heating glove is automatically turned off.

The heating gloves are made according to the accepted standards of standard sizes of gloves. All the technical components that ensure the operation of the heating glove are securely covered with protective insulating layers, so using the device to heat the hand is absolutely safe.

The time of continuous operation of the heating gloves without recharging is from 2 to 8 hours - it depends on the external temperature and thermal conductivity of the glove material. The heating gloves use high-quality 900 mAh lithium-ion polymer batteries without a memory effect, which cannot be damaged by frequent charging and are designed for approximately 500 charge / discharge cycles.

Heating gloves are able to heat up and thus heat the internal volume to a comfortable temperature (30 ... 40 ° C) when powered not only by the built-in lithium-ion polymer battery, but also from any, including autonomous current sources, in particular from any car battery, as well as from a portable battery with a voltage of 12 ... 15 V DC. It is advisable, in some cases, the use of heating gloves, for example, on long trips in car bodies or in any specially not heated cabins of other vehicles. At the same time, the problems with the electric capacity of current sources are greatly simplified, since energy-consuming automobile batteries (with running generators) can always be used as a current source, and in this case there is no need to think about energy savings during generator operation.

When using gloves heating in rooms (if necessary), there is no need to use autonomous power sources for heating, since it is quite acceptable and advisable to use various kinds of DC and AC chargers that are widely used in everyday life. The electrical parameters of these universal devices such as "ADAPTOR" are quite acceptable for the operation of heating gloves. They are reliable, small-sized and suitable for all their electrical parameters; they are powered by 220 V AC, i.e. from the city electric network.

The total continuous operation time of the heating gloves is determined by the electric capacity of the current source used. For example, a current source having an electric capacity of 2 Ah, at a discharge current of 200 mA, is able to heat the hands (generate heat) continuously for 7 ... 8 or more hours.

There are many different design options for placing and securing fuel elements inside the heating gloves.

The combination of high temperature resistance of Dacron filaments with resistive silver sputtering, coaxially placed on the upper plane of the heated layer of the heating glove and low electrical conductivity of the reflective layer, coupled directly with the material of the insulating layer, for example, by applying a metal foil to the insulating layer by vacuum evaporation allows the use of a flexible, durable wire, made of dacron yarns with resistive silver plating. The temperature of heating of lavsan filaments with a resistive deposition of silver depends on the current density flowing through a conductive layer of lavsan filaments with a resistive deposition of silver, which is directly related to the magnitude of the electric voltage supplied to specially formed current-carrying tires, previously applied to the second layer of heating gloves - a layer with placed heated mats 1, 2, 3 ,.

The technical and economic efficiency of heating gloves lies in the fact that the use of dacron filaments with resistive spraying of silver can reduce its geometric dimensions, provide better thermal contact between the two environments and, accordingly, increase the efficiency of heat transfer from heating elements.

Effect: quick and reliable heating of the glove, heating of the hands to a predetermined temperature, as well as a more complete and efficient use of the heat released by the heating elements, the efficiency is increased, which allows the maximum use of the thermal energy of electric heaters to heat the hands.
