DETAILED DESCRIPTION OF THE INVENTION

[0015] The booth assembly set and booth assembly of this embodiment will be described below.

[0016] FIG. 1 is a perspective view showing the exterior of a booth assembly set 50 according to an example of this embodiment. The booth assembly set 50 is a set for assembling the booth assembly 1. FIG. 2 is an external perspective view showing the booth assembly 1 that is assembled using the booth assembly set 50. As shown in FIG.

[0017] The booth assembly 1 is erected on a floor 100 in a medical facility such as a hospital or clinic as an installation surface. The booth assembly 1 has an inner space 7 surrounded by a ceiling surface 3 and side wall surfaces 5. The ceiling surface 3 and the side wall surfaces 5 are connected to each other. In the example shown in FIG. 2, the ceiling surface 3 is a surface parallel (horizontal) to the floor 100. In the example shown in FIG. 2, the side wall surfaces 5 are surfaces extending in a direction parallel to the normal direction (vertical direction) of the floor 100. The shape of the side wall surfaces 5 is the same as the side surfaces of, for example, a polygonal prism, a circular cylinder, or an elliptical cylinder. Examples of polygonal prisms include a triangular prism, a square prism, a pentagonal prism, and a hexagonal prism. In the example shown in FIG. 2, the side wall surfaces 5 have the same shape as the side surfaces of a square prism and have four side surfaces 5a, 5b, 5c, and 5d.

[0018] The booth assembly set 50 includes a frame body 10, a first sheet material 20, and a second sheet material 60.

[0019] The frame body 10 is made up of a plurality of frames 11, 13 that extend along the edges of the ceiling surface 3 and the side wall surfaces 5 and are connected to one another. The frames 11, 13 are each linearly extending members, with the frame 11 arranged to extend horizontally and the frame 13 arranged to extend vertically. The frames 11, 13 are made of a metal such as steel or an aluminum alloy, or a resin, for example.

[0020] The frame 11 constitutes a horizontal frame 15 of the frame body 10 that is aligned with the edge of the ceiling surface 3. In the illustrated example, the horizontal frame 15 is made up of four frames 11 connected to one another. The horizontal frame 15 is provided with two reinforcing frames 15a, 15b and two other reinforcing frames (see FIG. 1 ) extending between the reinforcing frames 15a, 15b in a direction perpendicular to the extension direction of the reinforcing frames 15a, 15b, to form an opening (not shown) in which a mounting frame 39 (described below) for mounting the air blower 30 to the frame body 10 is disposed. These reinforcing frames form a support frame 16 that surrounds the opening and supports the mounting frame 39 from below. The upper surface of the support frame 16 is positioned so as to overlap the edge of a vent hole 21a of a first ceiling surface sheet 21 (described below).

[0021] In the illustrated example, the frames 13 are the main bodies of the support posts 17 that are arranged along the edges of the side wall surfaces 5 of the frame body 10. In the example shown in Fig. 1, there are four frames 13, which are connected to the frame 11 so as to extend vertically downward from the four corners of the horizontal frame 15. A bottom 14 made of metal, resin, or rubber that comes into contact with the floor 100 is provided at the lower end of the frame 13.

[0022] The first sheet material 20 is attached to the frame body 10 to form the ceiling surface 3 and the side wall surfaces 5. The first sheet material 20 is composed of at least one first sheet. In the example shown in FIG. 1 , the first sheet material 20 includes a ceiling surface first sheet 21 that forms the ceiling surface 3 and four side surface first sheets 23 that form the side wall surfaces 5. In this way, the first sheet material 20 can be arranged on each surface surrounding the inner space 7, which makes it easy to attach the first sheet material 20 to the frame body 10. Alternatively, the first sheet material 20 may be composed of a bag-shaped sheet in which the side surface first sheet and the ceiling surface first sheet are integrated. This bag-shaped sheet is attached to the frame body 10 by covering the frame body 10 from above.

[0023] In the illustrated example, the first ceiling sheet 21 is provided with a vent hole 21a that allows gas to circulate between the inner space 7 and the outer space. The vent hole 21a may be provided in the first side sheet 23 instead of in the first ceiling sheet 21. The outer space refers to a space that is adjacent to the inner space 7 across the ceiling surface 3 and the side wall surface 5.

[0024] The first sheet material 20 includes a portion that forms a replacement area, which is at least a portion of the ceiling surface 3 and the side wall surface 5. The replacement area is an area that is determined, for example, in response to a patient's desire not to have the inside of the booth seen from the outside, or a medical professional's desire not to have the outside of the booth seen from the inside. The replacement area is preferably at least one of the multiple side surfaces 5a to 5d that surround the inner space 7 from different directions. In the following description, an example will be given in which the replacement area is formed on two surfaces, side surface 5a and side surface 5b. In this example, the portion of the first sheet material 20 that forms the replacement area refers to the two side surface first sheets 23 that form side surface 5a and side surface 5b.

[0025] The booth assembly set 50 further includes attachment means (not shown) for attaching the first sheet material 20 to the frame body 10, such as a hook-and-loop fastener, adhesive tape, an adhesive gel sheet, or a magnet. The hook-and-loop fastener may have, for example, one loop or one hook provided on the frame body 10 and the other provided on the first sheet material 20. Alternatively, one loop and one hook may be provided on each of the portions of the first sheet material 20 that are connected to each other. The adhesive tape and adhesive gel sheet may be provided on either the first sheet material 20 or the frame body 10, or on each of the portions of the first sheet material 20 that are connected to each other. The adhesive tape and adhesive gel sheet are preferably removably attached and detached. The adhesive tape is a tape coated with an adhesive. The adhesive gel sheet is an adhesive sheet made of, for example, a gel of polyurethane resin or silicone resin. The magnet is, for example, provided on the first sheet material 20.

[0026] The second sheet material 60 is a sheet material that forms the replacement area by replacing a portion of the first sheet material 20 that forms the replacement area. The second sheet material 60 is composed of at least one second sheet. The number and shape of the second sheets included in the second sheet material 60 are preferably the same as the number and shape of the first sheets that form the portion of the first sheet material 20 that the second sheet replaces. In the example shown in the figure, the second sheet material 60 includes two side wall second sheets 63. In the booth assembly 1 shown in FIG. 2, the portion of the first sheet material 20 that forms the replacement area is replaced with the second sheet material 60.

[0027] The booth assembly set 50 further includes, as replacement means (not shown) for replacing the replacement area with the second sheet material 60, for example, a hook-and-loop fastener, adhesive tape, an adhesive gel sheet, a magnet, or the like. A portion of the replacement means may be provided on the frame body 10 and the first sheet material 20, and in that case, a portion of the replacement means may also serve as the above-mentioned attachment means. For example, the hook-and-loop fastener has one of a loop and a hook provided on the frame body 10, and the other provided on the second sheet material 60. Alternatively, for example, one of a loop and a hook is provided on each of the portions of the first sheet material 20 and the second sheet material 60 that are connected to each other. The adhesive tape and adhesive gel sheet are provided, for example, on one of the second sheet material 60, the first sheet material 20, and the frame body 10, or on one of the portions of the first sheet material 20 and the second sheet material 60 that are connected to each other. The adhesive tape and adhesive gel sheet are configured similarly to the adhesive tape and adhesive gel sheet of the above-mentioned attachment means. The magnet is provided on the second sheet material 60, for example. The attachment means and replacement means are preferably provided so as to extend linearly along the edges of the ceiling surface 3 and the side wall surface 5.

[0028] In this embodiment, one of the first sheets 21, 23 and the second sheet 63 is a transparent sheet that transmits light (visible light), and the other is an opaque sheet that does not transmit light (visible light). In the example shown in the figure, the first sheets 21, 23 are transparent sheets, and the second sheet 63 is an opaque sheet. The transparent sheet is preferably a sheet made of a resin such as polyvinyl chloride, polyethylene, or polypropylene. The opaque sheet is, for example, a colored sheet made of a synthetic resin such as polyester or nylon, or a sheet made by bonding a colored sheet made of the above resin with an opaque resin. The color applied to the opaque sheet may be a chromatic color or an achromatic color.

[0029] According to the booth assembly set 50, after assembling the booth assembly 1 at the installation site, the portion of the first sheet material 20 that forms the replacement area can be replaced with the second sheet material 60, thereby making the replacement area transparent or opaque as appropriate. This allows the interior space 7 and the exterior space to be switched between being visible and invisible as appropriate.

[0030] The booth assembly 1 can be used, for example, as an isolation room for isolating patients infected with infectious diseases in medical facilities such as hospitals and clinics. In the booth assembly 1 installed in such a medical setting, the first sheets 21, 23 are preferably made of transparent sheets so that the condition of the patient inside the booth can be seen from outside the booth, or so that the patient inside the booth can see what is happening outside the booth (such as that someone has arrived). However, after assembling the booth assembly 1, there may arise a situation where a patient does not want to be seen lying in bed or sitting in a chair from outside, or wants the light to be blocked because of the bright sunlight, or a medical professional wants to prevent the patient inside the booth from seeing what is happening in the medical setting. The booth assembly set 50 allows the above-described switching between mutual visibility and mutual invisibility as needed to respond to such changing conditions. In particular, in medical settings, there is a demand to maintain the ceiling surface 3 and side wall surfaces 5 of the booth assembly 1 in a transparent state as a general rule, so if the first sheet material 20 is made up of separate sheets for the first ceiling surface sheet 21 and the first side surface sheet 23, it is possible to make only some areas opaque, which is preferable. Furthermore, if the first sheet material 20 is made up of separate sheets for the first ceiling surface sheet 21 and the first side surface sheet 23, it is possible to replace the first sheet material 20 for each partial area, making work at the installed location easier than when these sheets are in the form of a single bag.

[0031] The replacement area of ​​the booth assembly set 50 is not limited to the side surfaces 5a and 5b of the side wall surfaces 5 as in the example described above, but may be one, three, or four (all) surfaces of the side wall surfaces 5, or may be the ceiling surface 3 instead of the side wall surfaces 5, or may be the ceiling surface 3 in addition to the side wall surfaces 5.

[0032] The replacement area may also be a partial area of ​​each of the ceiling surface 3 and the side surface of the side wall surface 5. For example, with respect to the side wall surface 5, the vertical area on the side wall surface 5 through which the line of sight is directed from the inside of the booth to the outside or from the outside of the booth to the inside is often the central area of ​​the side wall surface 5, excluding the upper end area on the ceiling surface 3 side and the lower end area on the floor 100 side. Therefore, by designating only the central and lower end areas of the side surface of the side wall surface 5 as the replacement area, it is possible to ensure that the areas that can be obscured from each other are opaque while ensuring a larger area where the inside and outside of the booth can see each other. Such a replacement area is preferably a height area of ​​90% or less, more preferably 25 to 80%, of the height of the booth assembly 1 from the floor 100. In this case, the portion of the sheet material forming the upper end area of ​​the side surface may be a hat-shaped sheet integrated with the portion of the sheet material forming the ceiling surface 3.

[0033] The booth assembly set 50 further includes a blower 30 .

[0034] The air blower 30 is a device that blows air so as to create a pressure difference between the inner space 7 and the external space by passing gas through the ventilation opening 21a. Specifically, the air blower 30 passes gas from the inner space 7 toward the external space, thereby lowering the pressure in the inner space 7 below the pressure in the external space and creating a negative pressure in the inner space 7. Conversely, the air blower 30 may be configured to pass gas from the external space toward the inner space 7, thereby raising the pressure in the inner space 7 above the pressure in the external space and creating a positive pressure in the inner space.

[0035] The air blower 30 has, for example, a fan 31 (see FIG. 3) that is driven to rotate by supplying electric power. The air blower 30 is provided with, for example, a power cord (not shown) through which electric power is supplied from an external source. From the viewpoint of suppressing the driving noise (noise) and power consumption that accompany the driving of the fan 31, it is preferable to use a small fan 31 (for example, a diameter of 150 to 200 mm and an output of 75 W).

[0036] From the viewpoint of cleaning the internal space 7 or the external space, the blower 30 preferably further includes an air filter 33 (see FIG. 3). The air filter is preferably a filter that meets the performance of a HEPA (High Efficiency Particulate Air Filter) filter, and for example, has a collection efficiency of 99.99 or more when measured using particles with a particle size of 0.3 μm. The cleanliness of the internal space 7 or the external space achieved by the blower 30 is, for example, class 100 to 10,000 (based on the U.S. Federal Air Cleanliness Standard 209E). The volume of air passing through the vent 21a by the blower 30 is, for example, 10 to 11 m when class 1000 is achieved. 3 / min, 20-22m when achieving Class 100 3 The ventilation rate (air changes per unit time) of the inner space 7 by the blower 30 is, for example, 60 to 147 times / hour when Class 1000 is achieved, and 120 to 293 times / hour when Class 100 is achieved.

[0037] The blower 30 of the example shown in FIG. 3 is a fan-equipped filter unit (FFU) in which an air filter 33 and a fan 31 are arranged in this order in the direction of airflow through the vent 21a. FIG. 3 is a diagram illustrating the airflow generated within the booth assembly 1. The blower 30 of the example shown in FIG. 2 is supported from below by the support frame 16 of the frame body 10 via a mounting frame 39. Note that in FIG. 2, the blower 30 is shown lifted slightly upward from the mounting frame 39 to show the air filter 33. The mounting frame 39 is a rectangular frame with an opening on the inside, and a gasket (not shown) is provided on the mounting frame 39 to prevent gas leakage between the mounting frame 39 and the edge of the first ceiling surface sheet 21 placed on top of the support frame 16, and between the blower 30 and the mounting frame 39. The air blower 30 is not limited to being mounted on the ceiling surface 3 via the mounting frame 39 in this manner, and the air blower 30 disposed in the inner space 7 or the outer space may be connected to the vent 21a via a duct (e.g., a hose) extending within the inner space 7 or the outer space. The number of air blowers 30 provided in the booth assembly 1 is one in the example shown in Fig. 2, but may be two or more.

[0038] The dimensions of the booth assembly 1 are not particularly limited, but may be, for example, 1500 to 2000 mm in width (X direction in FIG. 2), 1500 to 2500 mm in length (Y direction in FIG. 2), and 2000 mm in height (Z direction in FIG. 1). In the inner space 7, for example, a bed or chair for use by the patient can be placed.

[0039] The airflow generated by the blowing air passes through the ventilation opening 21a and a gap G provided between the floor 100 and the lower end 23a (see FIG. 3) of the first side sheet 23 or the lower end 63a (see FIGS. 2 and 3) of the second sheet material 60. The first sheet material 20 is preferably attached to the frame body 10 and the second sheet material 60 is preferably replaced so as to adjust the size of the gap G so that the pressure difference between the internal space 7 and the external space caused by the airflow is a predetermined value.

[0040] Spaces within medical facilities, such as isolation rooms for isolating patients infected with infectious diseases, are typically required to comply with specified guidelines regarding the indoor environment and cleanliness (e.g., "Hospital Facility Design Guidelines (Air Conditioning Equipment Edition) (HEAS-02-2013)" published by the Japan Medical and Welfare Equipment Association). These guidelines specify, for example, the desired pressure difference between the indoor and outdoor spaces. However, in booth assemblies used as isolation rooms, etc., it is difficult to adjust the pressure difference between the indoor and outdoor spaces to satisfy this pressure difference, and it is not easy to strictly monitor the pressure difference between the indoor and outdoor spaces to satisfy the guidelines. In particular, while large fans in air blowers can relatively easily adjust the pressure difference by adjusting their output, small fans are used at high output to ensure the same airflow as large fans, which limits the range of output adjustment, making it difficult to adjust the pressure difference by adjusting the output. In conventional booth assemblies, adjusting the size of the gap between the floor and the lower end of the portion corresponding to the side wall surface of the sheet material to adjust the pressure difference makes it difficult to achieve the pressure difference specified by the index, because a change of even a few millimeters results in a large fluctuation in the pressure difference. Therefore, it is preferable to adjust the size of the gap G to precisely adjust the amount of gas suctioned or discharged from the gap G, thereby precisely adjusting the pressure difference between the inner space 7 and the external space. In particular, even when a small-sized blower 30 with high output (e.g., 60 to 75 W) is used, the pressure difference between the inner space 7 and the external space can be precisely adjusted. Therefore, the booth assembly 1 can be suitably used as an isolation room in a medical facility.

[0041] The pressure difference is measured, for example, in accordance with HEAS-02-2013, using a digital differential pressure gauge to measure the differential pressure between the central portion of the inner space 7 and the outer space. The size of the gap G is, for example, greater than 0 mm and not more than 10 mm, or 0.5 to 5 mm. The pressure difference is preferably 0.5 to 5 Pa, and more preferably 2 to 3 Pa.

[0042] The gap G may be adjusted by adjusting the height of the support column 17. In this case, the gap G may be adjusted using, for example, a bolt (adjusting bolt) (not shown) that is provided between the frame 13 and the bottom 14 and that can adjust the height of the support column 17 by changing the amount that the support column 17 is screwed into the frame 13 in the length direction. Furthermore, the adjustment of the gap G may be performed by adjusting the height of the support column 17 in combination with the adjustment of the height positions of the lower ends 23a, 63a of the seats 23, 63 described above.

[0043] The booth assembly 1 can be used as an airborne infection isolation room, a protective environment room, an operating room, an emergency room, an intensive care unit (ICU), etc. in medical facilities such as hospitals and clinics. In particular, it is suitable for performing negative pressure air conditioning in airborne infection isolation rooms, etc., and positive pressure air conditioning in protective environment rooms, etc. Furthermore, the booth assembly 1 can be used not only in medical facilities but also in health and hygiene facilities such as public health centers.

[0044] (Variation) The booth assembly may also preferably be configured as in the modified example described below. The modified booth assembly differs from the booth assembly of the example described above in that, instead of the portion of the first sheet material forming the replacement area being configured to be replaced with the second sheet material, the portion of the first sheet material forming the switching area has a permeable switching sheet, which will be described later.

[0045] That is, the booth assembly of the modified example is a booth assembly having an inner space surrounded by a ceiling surface and side wall surfaces, and includes a frame body composed of a plurality of frames extending along the edges of the ceiling surface and the side wall surfaces, and a sheet material attached to the frame body and composed of at least one sheet that forms the ceiling surface and the side wall surfaces. The portion of the sheet material that forms a switching area, which is at least a portion of the ceiling surface and the side wall surfaces, has at least one transparency switching sheet (not shown) that can switch the transparency of light (visible light) between a transparent state that transmits light and an opaque state that does not transmit light. Like the booth assembly of the above example, the booth assembly of the modified example also includes a blower.

[0046] Like the replacement area of ​​the booth assembly in the above example, the transition area is an area determined in accordance with, for example, a patient's desire not to have the inside of the booth seen from the outside, or a medical professional's desire not to have the outside of the booth seen from the inside. Similarly to the booth assembly 1 in the above example, the side wall surfaces of the booth assembly in the modified example have multiple side surfaces that surround the interior space from different directions, and it is preferable that the transition area be at least one of the side surfaces. In the modified example, the transition area is, for example, a surface corresponding to two surfaces, side surfaces 5a and 5b, of the booth assembly 1 in the above example, but is not limited thereto. It may be a surface corresponding to one, three, or all four (all) of the side wall surfaces 5, or it may be a surface corresponding to the ceiling surface 3 instead of the side wall surfaces 5, or a surface corresponding to the ceiling surface 3 in addition to the side wall surfaces 5.

[0047] A preferred example of a transparency switching sheet is a light-controlling film that can be switched between a transparent state and an opaque state by switching the current-carrying state between on and off. The light-controlling film is a film (liquid crystal light-controlling film) with a laminated structure in which a liquid crystal layer is sandwiched between two transparent electrodes (conductive films) made of a material such as indium tin oxide (ITO), and this is sandwiched between two resin films such as polyester (PET). The liquid crystal light-controlling film is configured so that light transparency can be switched between a transparent state and an opaque state by switching the current-carrying state to control the orientation of the liquid crystal in the liquid crystal layer. In this specification, "non-transparent to light" refers to a haze value measured in accordance with JIS K7361-1 and JIS K7136 of 50% or more, preferably 80% or more, and more preferably 90% or more. "transparent to light" refers to a haze value measured in the same manner of less than 50%, preferably 20% or less, and more preferably 10% or less.

[0048] The electrode film of the liquid crystal light control film is connected to an external power source via a switch for switching the current-carrying state of the liquid crystal light control film. The liquid crystal light control film may be one that maintains an opaque state or a transparent state while the current-carrying state is on.

[0049] According to the booth assembly of the modified example, by switching the permeability switching sheet between a permeable state and an opaque state, it is possible to switch between a state in which the inner space 7 and the outer space are mutually visible and a state in which they are not visible, as appropriate. Furthermore, with the booth assembly of the modified example, such switching does not require the work of replacing the sheet material that forms the switching area, and switching can be performed easily.

[0050] The portion of the sheet material forming the switching area preferably further includes at least one transparent sheet that transmits light and is laminated on the permeability switching sheet. The transparent sheet is preferably configured similarly to the transparent sheet of the sheet material of the booth assembly 1 described above. In this case, as shown in FIG. 4, the thickness T2 of the transparent sheet 63c is preferably thicker than the thickness T1 of the permeability switching sheet 63b. FIG. 4 is a cross-sectional view showing the laminated permeability switching sheets 63b and 63c. Because light control films are generally thin, when used as permeability switching sheets, for example, the electrode film may bend every time a patient enters or exits the booth, which may cause localized stress and disrupt the operation of the light control film. In some booth assemblies, the sheet material is sometimes detached from and reattached to the frame body every time a patient enters or exits the booth. Therefore, by laminating the permeability switching sheet on a transparent sheet that is thicker than the permeability switching sheet, the lack of rigidity of the permeability switching sheet can be compensated for and the localized stress on the electrode film can be reduced. The thickness of the permeability switching sheet is preferably 0.5 mm or less, 0.4 mm or less, 0.3 mm or less, and 0.1 mm or more. On the other hand, the thickness of the transparent sheet is preferably 1 mm or less, 0.7 mm or less, 0.5 mm or less, and from the viewpoint of the strength of the curtain (sheet material), 0.2 mm or more. The thickness of the permeability electrode sheet is, for example, 0.27 mm, and the thickness of the transparent sheet is, for example, 0.3 mm. Furthermore, from the viewpoint of ensuring ease of assembling the booth assembly and ease of bending of the curtain (sheet material), the total thickness of the permeability switching sheet and the transparent sheet is preferably 1.5 mm or less, 1.1 mm or less, or 0.6 mm or less, and from the viewpoint of the strength of the curtain (sheet material), 0.3 mm or more. The total thickness is, for example, 0.57 mm. On the other hand, the sheet material forming the switching region may be composed of only the permeability switching sheet.

[0051] Furthermore, in order to reduce the local load on the electrode film of the light control film, it is also preferable to laminate the light control film on the transparent sheet so that it is positioned on the side of the transparent sheet that is closer to the inner space 7. When the sheet material is removed from or attached to the frame body, it curves so that it is convex toward the inner space 7, so by laminating the light control film on the transparent sheet so that it is positioned closer to the inner space 7 than the transparent sheet, it is possible to reduce the local load on the electrode film.

[0052] It is preferable not to locate the switching area on the part of the sheet material that forms the side that serves as the patient's entrance and exit, as this is more likely to result in localized stress being applied to the sheet material when patients enter and exit than on the other parts of the sheet material.

[0053] When the transparency switching sheet is made of a light-controlling film and is provided on multiple side surfaces of the side wall of the booth assembly, it is preferable that the light-controlling film be configured as a single film connecting the multiple side surfaces. In this case, switching between the transparent state and the opaque state can be performed by a single switching operation of the power supply state, making the switching operation easy. On the other hand, it is also preferable that one light-controlling film is provided on each of the multiple side surfaces. In this case, the transparent state can be switched between the transparent state and the opaque state for each side surface depending on the situation, allowing for precise response to various changes in conditions. For these reasons, it is preferable that the light-controlling film be provided on all side surfaces of the side wall. In this case, as mentioned above, the side of the side wall that serves as the patient's entrance and exit is more likely to be subjected to localized loads on the light-controlling film 63b than the other sides. Therefore, by configuring the side surface to be openable and closable with a fastener, as shown in the example of Figure 5, localized loads can be reduced compared to when the side surface is removed from and attached to the frame body. Figure 5 is an external view showing an example of a sheet material. The sheet material shown in Fig. 5 has a slit formed to extend vertically from the center of the lower end to the center of the upper end, and a fastener is provided along the edge of the sheet material forming the slit. The slit may be closed partway without reaching the upper end of the sheet material as shown, or it may reach the upper end of the sheet material. One of the side wall surfaces of the booth assembly is preferably configured to be opened and closed with a fastener to provide an entrance and exit for the patient, as shown in Fig. 5.

[0054] Furthermore, similar to the replacement area of ​​the booth assembly in the above example, the switching area of ​​the booth assembly in the modified example is preferably only the central and lower end areas, or only the central area, of the height direction of the side surface of the side wall surface 5, and such a switching area is preferably a height area of ​​90% or less, more preferably 25 to 80% of the height of the booth assembly from the floor 100. In this case, the portion of the sheet material that forms the upper end area of ​​the side surface may be a hat-shaped sheet that is integrated with the portion of the sheet material that forms the ceiling surface.

[0055] The booth assembly set and booth assembly of the present invention have been described in detail above, but the booth assembly set and booth assembly of the present invention are not limited to the above-described embodiments, and it goes without saying that various improvements and modifications may be made within the scope of the gist of the present invention.

[0056] For example, in the booth assembly set 50, the first sheets 21 and 23 may be opaque sheets and the second sheet 63 may be a transparent sheet, contrary to the above example. [Explanation of symbols]
