Description

[Technical Field]

[0001] This invention relates to a collapsible, portable summer shelter equipped with heat-shielding curtains or sheets as a measure against heatstroke and air conditioning equipment. [Background technology]

[0002] The working environment in factories can easily become very hot in the summer, potentially affecting the health of workers. Heatstroke, in particular, is a serious problem and requires countermeasures. On April 15, 2025, the Ministry of Health, Labor and Welfare issued a revised ministerial ordinance requiring businesses to take measures against heatstroke, with penalties attached. The ordinance will come into effect on June 1. This applies to work in an environment with a heat index of 28 or higher or a temperature of 31°C or higher for more than one continuous hour or more than four hours per day. Businesses that fail to take countermeasures face imprisonment of up to six months or a fine of up to 500,000 yen. Many factories face significant challenges in complying with these requirements, as they often require workers to work or operate machinery in close proximity to heat-generating equipment.

[0003] Due to global warming in recent years, the temperature inside factories is rising due to radiant heat from building roofs and walls, and in order to keep the heat index at 28 or the temperature at 31°C or below, it is considered necessary to expand and strengthen air conditioning equipment. However, due to the large space inside factories, this is not expected to be very effective, and it would also be a large economic burden.

[0004] Patent Document 1 presents a mobile summer rest area with casters, but it has a simple structure with blinds simply placed on the side walls.

[0005] Patent Document 2 presents a multipurpose portable tent, and describes the materials of the sheet as UV-blocking fabric, heat-shielding fabric, complete shading fabric, etc.

[0006] Patent Document 3 describes a greenhouse for plant cultivation in which both sides of a glass cloth are coated with aluminum foil as a heat shield sheet.

[0007] Patent Document 4 presents a combination of a metal thin film sheet and an embossed sheet, and although it has a heat-shielding and heat-insulating effect, there is no mention of application as a heat-shielding sheet in a summer resort.

[0008] Non-patent document 1 is a catalog of Lead Giken Co., Ltd., and describes a heat shielding sheet called "EMW Heat Shield Sheet GI" which has aluminum sheets on both sides of a glass cloth, and a heat shielding sheet called "EMW Heat Shield Sheet G-II" which has aluminum foil bonded to both sides of a polystyrene sheet formed into a honeycomb structure.

[0010] Indoor temperatures in factories and other places can get very high in the summer, putting workers at risk of heatstroke. Working around boilers and drying furnaces in particular is a constantly hot environment, and the Ministry of Health, Labor and Welfare has made heatstroke prevention measures mandatory, with penalties attached, for working in an environment with a heat index of 28 or higher or a temperature of 31°C or higher for more than one hour continuously or for more than four hours a day, but adhering to these standards is extremely difficult.

[0011] Therefore, the purpose of this invention is to provide a collapsible, portable summer shelter as a measure to prevent heatstroke among workers in workplaces such as factories. [Means for solving the problem]

[0012] The collapsible portable summer shelter to achieve the above-mentioned object has a metal or resin pipe assembly frame or a collapsible tent frame, the walls are made of highly insulating glass cloth on both sides of which flame-retardant curtains with a heat-shielding sheet coated with a highly reflective metal thin film attached to one side are hung, the ceiling is covered with a multi-layer heat-shielding sheet made of aluminum foil and an air layer of polyethylene foam, and the bottom has casters.

[0013] In addition, a transparent heat-shielding film can be attached to one side of a noren-style transparent curtain on one to four of the wall surfaces, allowing the outside to be seen from inside.

[0014] In addition, a wall-shaped board can be fixed to a base with casters, and a mobile air conditioning unit with an outdoor and indoor unit can be connected.The frame pipes can also be made extendable, allowing the shape and size to be adjusted to suit the installation location. [Effects of the Invention]

[0015] The portable, collapsible summer shelter of this invention allows workers to temporarily escape from a hot environment to a cooler one, helping to prevent heatstroke. By entering this summer shelter, workers can temporarily escape from a hot environment and avoid continuous work.

[0016] In addition, the walls can be fitted with transparent curtains or noren-style transparent curtains to allow visibility outside, allowing users to keep track of the status of the equipment and the surrounding work area. Furthermore, the noren-style curtains allow for entry and exit from any direction.

[0017] In addition, a wall-like board can be fixed to a base with casters, and a mobile air conditioning unit equipped with an outdoor and indoor air conditioner unit can be connected, with a power outlet provided, making it possible to work on a computer.

[0018] This allows people to temporarily escape from a hot environment to a cooler one, making it possible to prevent heatstroke. People can stay in the summer shelter without any problems while working outside.

[0019] In addition, the size of the frame pipes can be adjusted by making them extendable, so that the size can be adjusted to fit the shape of the work area as much as possible when installing it. [Brief explanation of the drawings]

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the collapsible movable summer shelter of the present invention will be described in detail with reference to the drawings.

[0022] Figure 1 is an external view of a collapsible portable summer refuge as one embodiment of the present invention. The collapsible portable summer refuge is collapsible, with a frame made of metal or resin pipes, etc., and the walls are made of a heat-shielding sheet made of highly insulating glass cloth coated with a highly reflective metal thin film on both sides, attached to a fire-retardant curtain 1. The ceiling is made of a multi-layer heat-shielding sheet 2 made of aluminum foil and an air layer of polyethylene foam, placed on top of the frame, and casters 4 are attached to make it movable.

[0023] As a heat shielding sheet for walls, for example, a 0.2 mm thick heat shielding sheet (EMW-GI manufactured by Lead Giken Co., Ltd.) consisting of three layers of surface-coated aluminum foil + glass cloth + surface-coated aluminum foil is used. As a multi-layer heat shielding sheet with an air layer for ceiling surfaces, a 20 mm thick multi-layer heat shielding sheet (EMW-GIIHGW manufactured by Lead Giken Co., Ltd.) consisting of aluminum foil + polyethylene foam core (diamond-shaped) + aluminum foil + polyethylene foam core (diamond-shaped) + aluminum foil, with two air layers and three layers of aluminum foil, is used.

[0024] Figure 2 shows the exterior configuration of a summer retreat equipped with a movable air conditioning system. A heat-shielding film is attached to one side of a noren-style transparent vinyl curtain, allowing the outside to be seen, and the indoor air conditioning system is a movable panel structure with casters that combines an outdoor unit 7 and an indoor unit 8 into one unit, which is part of the room.

[0025] These panels will be fitted with power outlets, allowing for the use of computers and other devices. Heat treatment is required during the manufacturing process within factories, and workers are constantly exposed to heat radiation, which poses a risk of heatstroke while working. To eliminate this risk, a compact summer shelter equipped with air conditioning and located as close to the work area as possible is effective. Making the summer shelter compact minimizes the inconvenience of reduced work space. [Example]

[0026] In order to confirm the heat-shielding performance of the transparent curtain attached with the heat-shielding film used in this invention, a heat-shielding performance test was conducted using an infrared heater.

[0027] As shown in Figure 7, a vinyl curtain with a heat-shielding film attached was placed in front of the infrared heater as a test specimen, and the radiation temperature was measured on the backside. As a result, as shown in Figure 8, in the case of a 300W infrared heater, for example, the temperature was 31.2°C for the vinyl curtain with the heat-shielding film attached and 66.5°C for the one without the heat-shielding film, a temperature difference of 35.3°C was confirmed.
