Description

The invention relates to tents and is a tent with the ability to safely heat its internal volume by radiation from an external source, such as the sun, a fire, etc., while ensuring its safe operation at any time of the day.

A tent with a tubular frame, an awning with windows made of organic materials, entrance panels, ventilation holes and a removable floor is known, and the tent is provided with an inner insulation with a metallized film and sheathed on both sides with synthetic fabric (according to application 2001116898/20, 08.06 .2001, applicant: Voenohot-4 Plant Limited Liability Company, authors: Silantyev S.V., Ignatenko A.A., Kozlova L.A., Fedoseyeva N.A.).

The presence of a common layer of metallized film on the entire surface of the tent does not allow you to adjust the radiation, including thermal radiation from an external source, such as the sun or a bonfire. In addition, the tent is not distinguishable in the dark and requires the use of a light source to enter or exit the tent in the dark. The area of the windows available in the tent is much smaller than the area of the walls, which only makes it possible to use solar radiation to heat the inner volume of the tent, while it is practically impossible to use the radiation of a fire located outside the tent to heat its internal volume. The location of the fire close to the tent can lead to the fire of the tent and its stretch marks.

Also known is a portable infrared tent with field heating, comprising a freestanding enclosure having a frame supporting flexible walls of the enclosure and having at least one side opening opening hatch (according to US patent US 20140190537 A1 of July 10, 2014 with priority from 8 January 2013, authors Stephen J. Bend, Bend Chad Matthew, Robert E. Loukus).

The use of tent heating through infrared heating with elements fixed on the inner surface of the case to heat the patient makes it more voluminous and specialized in use. In addition, heating the space inside the tent through infrared heating requires connection to additional equipment. Also, the design of the tent does not guarantee the safety of the user from colliding with vehicles at the campsite, as well as quick evacuation in emergency situations, especially in the dark. Heated from an external source (bonfire or sunlight), which is most acceptable for tourists, for this option, tents are not provided.

The closest analogue is a tent containing a front wall made of a material permeable to radiation, and a protecting element made of a material whose inner surface is capable of reflecting radiation (RF patent 2257451). The surfaces of the enclosing element are arranged so that together they are a reflector capable of reflecting radiation from an external source located opposite the front wall to a limited area inside the tent, for example to the floor. The design of the tent allows you to increase the density of reflected radiation in the area of the floor and achieve a comfortable temperature with less power from an external radiation source. The tent, in camping conditions or in an emergency, in sunny weather, can provide fuel savings for heating, and also increases the chances of survival in the event of a dangerous drop in air temperature, if it is possible to use natural fuel for a fire located outside opposite the front wall of the tent.

Using a campfire as a heater for the inside of the tent is unsafe and should be extremely careful. The heating of the tent fabric, the ingress of sparks, coal from the fire on the tent canvases and on its stretch marks can lead to its ignition. In addition, there is a need to reinstall or overlap the tent when changing the radiation source to reduce the heating of the tent from sunlight. Also, the tent and its stretch marks with pegs at night can cause injury from stumbling over them. In addition, when using a tent in places of mass accommodation of campers (for example, in a campsite), there is a risk of vehicles colliding with the tent. Also, when leaving the tent or entering it at night, it becomes necessary to use a light source.

In solving this problem, a technical result was achieved - when using radiation from an external source, reflection was received from the lower and upper external contours of the tent’s enclosing elements, radiation in the direction of that part of the enclosing element that performs the function of the tent’s floor, with the concentration of reflected radiation in the place for people in the tent provides additional protection against radiation by using a reflective coating of the lower and upper surfaces of the building envelope and stretch marks olotna reflecting electromagnetic radiation with a wavelength of 2⋅10 ^-7 to 2⋅10 ^-3 meters. Moreover, the height and width of the reflective sheet surfaces of the enclosing structural elements occupy no more than 1/3 of the total height and width of the outer surface of the tent. The reflective lower side canvases of the tent and parts of stretch marks allow, together with the use of special fire-resistant impregnations with fire retardants, to protect the structure of the tent from fire not only from a fire, but also from a grass fire. When testing tent materials, an increase in the fire resistance of materials was established not only from the use of impregnations to increase fire resistance, but also from a mixture of special reflective coatings, for example, impregnation with flame retardants (for example, manufactured by TRANSFORMER LLC) and a reflective coating of fluorescent pigment (for example, NoxtonTechnologies production) composition with various adhesive coatings. The use of luminous coatings (paints), for example, a phosphor (for example, manufactured by "Noxton Technologies") in a composition with various adhesive coatings, to indicate the dimensions of the tent and its contour, stretch marks, pegs, sliders with zippers and fasteners at the entrance to the tent allows them to give visible dark electromagnetic radiation of wavelength from 4⋅10 ^-7 to 8⋅10 ^-7 meter and reduce the risk of injury during operation of the tent, vehicle collision, hesitation person per pegs or extensions, or untimely escape dark time of day.

The proposed tent is illustrated by drawings,

where in FIG. 1-4 shows a tent with the ability to safely heat from an external source and perform electromagnetic radiation with a wavelength of 4⋅10 ^-7 to 8⋅10 ^-7 meters to indicate its dimensions and location on the ground, as well as the position of entry and exit from it:

in FIG. 1 is a front view of the tent with the distribution of heat flux from the fire;

in FIG. 2 - side view of the tent;

in FIG. 3 is a side view of the tent when a grass fire spreads;

in FIG. 4 is a front view of the tent.

The tent with the possibility of heating from an external source contains the main body of the enclosing element with canvases 9 with coatings 11 that transmit electromagnetic radiation with a wavelength of 2⋅10 ^-7 to 2⋅10 ^-3 meters from the outside, and canvases 8 and 10 and stretch marks 2 s type 12 coatings reflecting this radiation. The inner walls of the canvases of the enclosing elements of the tent contour have coatings with the property of reflection of electromagnetic radiation with a wavelength of 1⋅10 ^-6 to 2⋅10 ^-3 meters and allow heat to accumulate in the inner space. The inner coating of the canvases, reflecting electromagnetic radiation with a wavelength of 1⋅10 ^-6 to 2⋅10 ^-3 meters, can be made with the ability to unfasten, reduce or change their position (transfer to the upper position), which allows a flexible response to changing conditions operation of the tent in real conditions.

Stretch marks 2 tents are fixed on the ground with 7 pegs 1. The contour of the tent forms the location of pegs 1, the upper part (ridge) 4 tents, stretch marks 2 and its lateral sides 3 have alternating reflecting electromagnetic radiation with a wavelength of 2⋅10 ^-7 to 2⋅10 ^-3 meters, a reflective coating of type 12, which emits electromagnetic waves during the night from 4710 ^-7 to 8⋅10 ^-7 meters in length, a luminous coating 13.

The height of the lower fabric 10 with a reflective coating 12 is also impregnated with flame retardants, which serves to prevent fire from a grass fire that may occur from a spark of a fire or come from another source of ignition. Moreover, the height h _{2 of the} location of the upper boundary of the side web 10 exceeds the height of ignition of the mowed (crushed) grass near the tent or hit by a flying spark from the fire. The height h ₂ depends on the design of the tent, its area, the condition of the grass around it and, approximately, can be established from the expression for cases where the state of the grass cover on which the tent is located and the probable flame length

- длина пламени; α - угол наклона пламени.Where

- flame length; α is the angle of inclination of the flame.

In the absence of such information, it is accepted from the condition

- смещение крепления палатки от ее контура, i=1…n, n - количество вариантов крепления растяжек;

и

- смещения по горизонтали нижнего участка полотна 10; с₁ - горизонтальная проекция верхнего отражающего лучи полотнища, С - ширина основания палатки; Н - высота палатки; h₁ - высота верхнего полотнища.

- displacement of the tent mounting from its contour, i = 1 ... n, n - the number of mounting options for stretch marks;

and

- horizontal displacement of the lower portion of the web 10; C ₁ - horizontal projection of the upper reflective rays of the cloth, C - the width of the base of the tent; H - the height of the tent; h ₁ - the height of the upper panel.

The same height h ₁ has a reflective surface 12 of the canvas on all sides of the tent.

The difference between the reflective sections of the coating 12 of the stretch and the luminous 13 is made from its lower part with a height h. Radiating electromagnetic waves with a length of 4 до10 ^-7 to 8⋅10 ^-7 meters, luminous coatings of type 13 of the frame on the tent should allow a person to visually establish its dimensions in the dark.

At the entrance to the tent, emitting electromagnetic waves from 4⋅10 ^-7 to 8⋅10 ^-7 meters long, glowing in the dark, there is at least a luminous coating 13 of the runner (s) 5 of the fastener 6, which allows opening the entrance in the dark days without the use of additional lighting.

When using an artificial radiation source, such as bonfire F, the tent is located to it one of its lateral sides. The distance from the campfire F to the tent should satisfy the fire safety requirements and be beyond the contour of the tent and its fasteners, i.e. L >> max (b _i ).

To receive radiation of electromagnetic waves from 4 -10 ^-7 to 8 -10 ^-7 meters long from the luminous coating in the dark, the tent enclosing and fastening elements that determine the dimensions and location of the tent on the ground, as well as the structural elements that indicate the entrance to the tent and way out of it, it is necessary to find these elements in the daytime under electromagnetic radiation with a wavelength of 2⋅10 ^-7 to 1⋅10 ^-6 meters (visible optical spectrum).
