Description

Technical Field

[0001] The present invention provides a tent heat insulation structure that can contribute to heatstroke prevention by attaching a heat insulation sheet to the ground surface side of an event tent or the like used outdoors.

Background Art

[0002] Event tents used outdoors prevent sunlight by coating the surface of the tent base with a material that reflects radiant heat or by kneading a reflective material into the tent base.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Therefore, there were the following problems. Outdoor tents are mainly for shading, and materials that absorb sunlight are mainstream. However, in recent years, due to global warming, the amount of solar radiation has increased, and the proportion of heat absorbed by the tent base is increasing significantly, and the environment under the tent is becoming very hot. Therefore, various methods of reflecting sunlight have been devised. For example, methods such as kneading a reflective material into the tent base or coating the surface of the tent base with a material that reflects radiant heat have been implemented. However, even if it is reflected by the tent base, most of the heat that passes through or is absorbed is radiated to the ground surface side, so the amount of heat under the tent is not at all small and can also be a factor in heatstroke. The present invention has been made to solve these problems.

Means for Solving the Problems

[0007] The best mode for implementing this invention will be described below. The primary source of heat for Tent 2, which is used outdoors, is radiant energy from the sun, also known as radiant heat. While some of this radiant heat is reflected by the surface of Tent 2, most of it is absorbed by the Tent material 1 or transmitted through it and radiated towards the ground. In addition to the radiant heat absorbed by the tent fabric 1, heat is also absorbed by air conduction and convection due to wind, and this heat is transmitted from the atmospheric side to the ground surface of the tent fabric 1 in the form of conductive heat. Subsequently, heat is transferred from the ground-facing surface of the tent fabric 1 back to the ground surface in the form of conduction and radiation. Of these, radiation accounts for the largest portion, making up more than 90% of the total heat. Therefore, the amount of heat transferred to the ground surface through tent 2 is the sum of this radiant heat and the radiant heat transmitted through tent material 1. Radiant heat, in the form of electromagnetic waves, is emitted to people inside Tent 2 and is the biggest factor in why people feel hot. Therefore, blocking this radiant heat is considered an effective measure against heatstroke and other related problems.

[0008] This invention is a tent heat shielding structure in which a heat shielding sheet 4 made of a material with high reflectivity against radiant heat, such as aluminum foil, is attached to the ground surface of an event tent 2 or sunshade made of resin sheet.

[0009] As mentioned earlier, more than 90% of the conductive heat absorbed by the tent fabric 1 is radiated back to the ground as radiant heat from the ground side of the tent fabric 1. When a heat-shielding sheet 4 made of a material with high reflectivity to radiant heat, such as aluminum foil, is attached to the underside of the tent fabric 1, more than 95% of the radiant heat emitted from and transmitted from the tent fabric 1 is reflected back to the tent fabric 1. Therefore, only a few percent of the heat is transferred to the ground surface side of the heat-shielding sheet 4. In this way, the area beneath tent 2 can be made into an extremely shaded space where radiant heat is not emitted from the tent fabric 1.

[0010] The heat-shielding sheet 4 is made by heat-welding a material with high reflectivity to radiant heat, such as aluminum foil, to one or both sides of a nonwoven fabric or glass fiber. Materials with high reflectivity against radiant heat, such as aluminum foil, are preferred because their purpose is to reflect radiant heat. Generally, materials with a reflectivity of 95% or higher are used. The thickness of the heat-shielding sheet 4 is typically 0.1 to 0.2 millimeters. Because it is thin, it is easy to fold, and the strength of the heat-shielding sheet 4 is increased by folding 20 to 50 millimeters around the edges 7 and bonding the two with acrylic double-sided tape or sewing them together with a sewing machine. Furthermore, grommets 5 are attached to the perimeter of the heat-shielding sheet 4 at intervals of approximately 30 to 50 centimeters. In addition, each grommet 5 has a cloth string about 20 centimeters long attached to it for attachment to the tent frame 3.

[0011] The heat shield sheet 4 is attached after the tent is assembled, by tying the fixing strings 6, which are tied to the grommets 5 of the heat shield sheet 4, to the tent frame 3 in order from the inside of the tent 2. [Effects of the invention]

[0012] The area under Tent 2 is in complete shade, protected from radiant heat, so you won't feel too hot when the temperature is below body temperature. Furthermore, even if the temperature rises above body temperature, a slight breeze will make you feel cooler. [Explanation of Symbols]
