The present invention will be described in more detail below with reference to the drawings, showing embodiments and specific examples, but the present invention is not limited to these embodiments and specific examples.
In addition, in the following explanation using the drawings, it should be noted that the drawings are schematic and the ratios of the dimensions, etc. may differ from the actual ones, and in order to make it easier to understand, illustrations other than those of parts necessary for the explanation have been omitted as appropriate.

(1) Overall Configuration of the Booth Fig. 1 is a perspective view of the main parts showing the internal configuration of a booth 1 according to this embodiment, and Fig. 2 is a plan view explaining the installation of the booth 1. The overall configuration of the booth 1 will be explained below with reference to the drawings.

As shown in Figures 1 and 2, the booth 1 is box-shaped and is equipped with a desk 11, chair 12, monitor 13, lighting 14, electrical equipment box 15, indoor air conditioner unit 16, and outdoor air conditioner unit 17 on the side. Users can sit on the chair 12 in the air-conditioned space formed within the booth 1, facing the desk 11 and monitor 13, and carry out various tasks such as work or study, or receive online services via telecommunications lines.

The booth 1 comprises a base 2 provided on the installation surface FL, a floor plate 3 provided on the base 2, a side wall panel 4 erected on the base 2, a ceiling panel 5 provided on the side wall panel 4, and casters 6 provided below the base 2 (see Figures 3(a) and (b)).

The base 2 is made of four beams joined together so as to form a rectangular shape corresponding to the bottom shape of the booth 1, and is made of, for example, square steel pipes.
The floor panel portion 3 is supported by contacting a floor support member provided so as to protrude inward from the base portion 2, and a floor mat is layered on top of, for example, structural plywood, which is a wooden board material.

The side wall panel 4 is made up of a first side wall panel 41 that constitutes the rear wall and has a first surface, a second side wall panel 42 that constitutes the left and right walls and has a second surface, a third side wall panel 43 that has a third surface, and a fourth side wall panel 44 that constitutes the front wall and has a fourth surface. The fourth side wall panel 44 has an opening 44a that serves as an entrance and exit, and a door 45 is attached to this opening 44a. In this embodiment, the door 45 is a sliding door. In addition, an electronic lock (not shown) that can be unlocked with an electronic key is attached to the door 45, making it possible to provide services such as rental.

The ceiling panel 5 is fixed to the upper end of the side wall panel 4 so as to cover the upper opening formed by the side wall panel 4, and is made of, for example, structural plywood, which is a wooden board material.

The casters 6 are provided at the four corners of the lower part of the base 2, and when the booth 1 assembled in a factory or the like is to be installed at the installation site, it is transported on the platform of a truck or the like, and at the installation site, it is moved using the casters 6 and installed on the installation surface FL.

Inside the booth 1, the desk 11 is placed on the floor panel 3, in contact with the third sidewall panel 43, which is on the right side when viewed from the fourth sidewall panel 44. Above the desk 11, a monitor 13, a light 14, and an electrical box 15 are placed in this order from bottom to top along the third sidewall panel 43. The air conditioning indoor unit 16 is placed above the first sidewall panel 41, with its air outlet facing from the floor panel 3 to the fourth sidewall panel 44.

An automatic fire extinguisher (hereinafter referred to as the fire extinguisher) 20 is also attached to the ceiling panel 5. The fire extinguisher 20 has a heat sensor 22b (see FIG. 5) that detects a specific temperature, and when it detects a specific ambient temperature, it sprays a fire extinguishing agent into the booth 1.

On the outside of the second side wall panel 42, which is on the left side as viewed from the fourth side wall panel 44, an air conditioning outdoor unit 17 is installed, which is connected to the air conditioning indoor unit 16 of the air conditioner. Below the air conditioning outdoor unit 17, an evaporator 18 that atomizes the drain water discharged from the air conditioning indoor unit 16 and the air conditioning outdoor unit 17 and discharges it into the atmosphere, and a secondary drain water tray 19 are arranged in this order along the direction of gravity.

The booth 1 thus constructed is constructed so that it can be assembled in a factory or the like, transported on the platform of a truck or the like, and installed on the installation surface FL at a predetermined installation location. The installation location can be an inside corner of a building frame, which is an example of an exterior space where passersby and users of the booth 1 are mixed, and it is preferably installed in an inside corner of a concourse space, a connecting passageway, etc. formed between a subway station and above-ground parts.
Specifically, as shown in Fig. 2, with respect to the two first wall surfaces X and second wall surfaces Y that constitute the inside corner space, the third side wall panel 43 is installed facing the first wall surface X of the inside corner space, and the first side wall panel 41 is installed facing the second wall surface Y of the inside corner space. By installing in this manner, the air conditioning outdoor unit 17 arranged on the outside of the second side wall panel 42 is positioned so as not to protrude into the aisle at the installation location of the booth 1 and not to obstruct the passage of people (indicated by arrow R in Figs. 1 and 2).

The installation location is not limited to the corner of the building frame, but can be freely placed in the external space. In this case, the booth 1 has an internal space formed by the side wall panel 4 and an air conditioning outdoor unit on one side of the internal space, and is preferably rectangular in plan view with short and long sides, with the side on which the door 45 is located facing the aisle or road where there is a lot of foot traffic. By reducing the depth direction of the booth 1, which is the short side, the booth 1 can be placed so as not to protrude into the aisle and not to obstruct the passage of pedestrians.

(2) Air Conditioning System and Fire Extinguisher (2.1) Configuration of the Air Conditioning System Figure 3(a) is a partial cross-sectional front view showing the internal configuration of booth 1, (b) is a side view of booth 1, (c) is a plan view of booth 1, and Figure 4 is a schematic diagram showing air circulation within the space of booth 1.

The booth 1 according to this embodiment is equipped with an air conditioning indoor unit 16, an air conditioning outdoor unit 17, an air intake 43A provided in the third side wall panel 43 on which the desk 11, monitor 13, lighting 14, and electrical box 15 are arranged, and an exhaust fan 30 provided in the ceiling panel 5, and forms an air conditioning system with the circulation of cool or warm air blown from the air outlet of the air conditioning indoor unit 16 and the air flow of outside air drawn in through the air intake 43A and exhausted by the exhaust fan 30.

As shown in FIG. 3(a), the third side wall panel 43 on the side where the monitor 13, lighting 14, and electrical box 15 serving as heat sources are arranged has an air intake 43A that communicates with the outside. The air intake 43A consists of a first air intake 43Aa provided on the outer surface of the third side wall panel 43 and a second air intake 43Ab provided on the inner surface of the third side wall panel 43, and the first air intake 43Aa and the second air intake 43Ab are provided in positions that do not overlap in a side view.

Specifically, the first air intake 43Aa is provided toward the center of the third side wall panel 43 in the horizontal direction, and the second air intake 43Ab is provided on the fourth side wall panel 44 side of the first air intake 43Aa. The first air intake 43Aa may be on the outer side of the second air intake 43Ab. In addition, in the vertical direction, the air intake 43A is provided so as to be above the desk 11 and within the height range of the monitor 13.

As shown in FIG. 3B, the exhaust fan 30 is provided on the ceiling panel 5 at a position close to the fourth side wall panel 44 on the third side wall panel 43 side in the vicinity of the fire extinguisher 20 in a plan view.
This creates an airflow, as shown by arrow A in Figure 4, in which external air is taken in from the back side of the monitor 13, which is one of the heat sources, passes around the lighting 14 and electrical box 15, which are other heat sources, and is exhausted to the outside via the exhaust fan 30 provided on the ceiling panel 5.
The monitor 13, lighting 14, and electrical box 15 serving as heat sources are arranged in this order along the third side wall panel 43 from the bottom to the top of the space, so that the heat from the heat sources can be efficiently exhausted to the outside of the booth.

The air outlet 16a of the air conditioning indoor unit 16 faces from the floorboard section 3 toward the fourth side wall panel 44, so that the air blown out from the outlet does not directly reach the heat sources of the monitor 13, the lighting 14, the electrical box 15, and the fire extinguisher 20 installed in the ceiling panel 5. This allows the initial heat of the fire to reach the air conditioning indoor unit 16 in the event of a fire and quickly begin extinguishing the fire (see the dotted area in Figure 4(a)), and also prevents condensation caused by the cold air from the air conditioning indoor unit 16, thereby preventing electrical leakage accidents.

(2.2) Arrangement of fire extinguisher Figure 5(a) is a side view showing the structure of fire extinguisher 20, (b) is a plan view, Figure 6(a) is an oblique view showing a cylindrical support, (b) is a perspective view showing an example of a support divided into multiple parts, Figure 7(a) is a perspective view showing an example of a polygonal support, (b) is a perspective view showing another example of a polygonal support, Figure 8 is a perspective view showing a box-shaped support, Figure 9 is a perspective view showing an example of mounting the support to the upper surface of a ceiling, Figure 10(a) is a schematic vertical cross-sectional view showing the fixing structure of fire extinguisher 20, (b) is a schematic plan view, and Figure 11 is a diagram explaining the size of the openings in the fire extinguisher body 21 and support 25, and the stability of fixing the fire extinguisher 20.
The fixing structure of the fire extinguisher 20 will be described below with reference to the drawings.

5, the fire extinguisher 20 is formed in a shape like two containers joined together from above and below, and is equipped with a fire extinguisher body 21 that contains an extinguishant inside, an extinguishant spray nozzle 22 that is located on the underside of the fire extinguisher body 21 and protrudes downward to spray the extinguishant inside in the event of a fire, and a heat sensor 22b that extends from the fire extinguisher body 21 into the space and detects the room temperature. The heat sensor 22b is made of a metal with good thermal conductivity, and when the end of the heat sensor 22 exceeds a predetermined temperature, it opens the nozzle hole of the extinguishant spray nozzle 22, making it possible to spray the extinguishant inside the fire extinguisher body 21.
In addition, a bracket portion 24 is attached to the upper portion of the fire extinguisher body 21 for mounting to a holder 27 provided on the ceiling panel 5 described later.

As shown in FIG. 10, the booth 1 in this embodiment is supported from below in the direction of gravity by a support 25 that is provided on the upper surface 5a of the ceiling panel 5 so as to surround the opening 51 and has an opening 25a that is smaller than the maximum outer diameter of the fire extinguisher body 21 and matches the outer shape of at least a portion of the fire extinguisher body 21.

As shown in FIG. 6(a), the support 25 is a cylinder having an opening 25a that matches the outer shape of at least a part of the fire extinguisher body 21 so that a part of the fire extinguisher body 21 can be installed inside, and a leg 25b is provided at the lower end for fixing to the upper surface 5a of the ceiling panel 5. In this embodiment, the fire extinguisher body 21 has a round shape like two container-like objects joined from above and below, and the support 25 is a cylinder so as to receive the lower surface 21a of the fire extinguisher body 21, but it may be configured by dividing it into multiple parts according to the outer shape of the fire extinguisher body 21, for example, as shown in FIG. 6(b). Note that FIG. 6(b) shows an example in which the support 25 is divided into three parts, but the number of divisions is not limited to this. By dividing the support 25 into parts, the cost can be reduced compared to a one-piece cylinder.

The support 25 may be a cylinder with a polygonal shape of three or more sides as shown in FIG. 7(a), and the polygonal cylinder may be a crown shape with each side formed concavely as shown in FIG. 7(b). Although a hexagonal support 25 is shown in FIG. 7, the support 25 may be a cylinder with a triangle or more sides, for example an octagon. In this way, the support 25 having a polygonal cylinder makes point contact with the fire extinguisher body 21, and is easy to follow the external shape of the fire extinguisher body 21. The support 25 may be a polygonal body or may be divided into multiple parts.

8(a), the support 25 may be a box-shaped body having an annular opening 25a that matches the outer shape of at least a part of the fire extinguisher main body 21. By making the support 25 a box-shaped body, the legs 25b for fixing the support 25 to the upper surface 5a of the ceiling panel 5 have rectangular surfaces, and the support 25 can be stably placed on the upper surface 5a of the ceiling panel 5.
In addition, the support 25 may be divided into a plurality of parts as shown in Fig. 8(b) in accordance with the outer shape of the fire extinguisher main body 21. By dividing the support 25 into parts, the cost can be reduced compared to a one-piece box-shaped body.

Also, as shown in FIG. 9, the support 25 may be formed so that the legs 25b extend outward from the cylinder so that the opening 25a does not block the opening 51 provided on the upper surface 5a of the ceiling panel 5 when the support 25 is installed on the ceiling panel 5. This allows the support 25 to be stably installed on the upper surface 5a of the ceiling panel 5.

A portion of the upper surface 5a may be protruded to match the outer diameter shape of the fire extinguisher body 21, or a cavity may be provided so that the fire extinguisher body 21 can fit into it. Of course, in addition to partially processing the upper surface 5a, a support may be used in combination to stably install the fire extinguisher container. In this way, the number of parts can be reduced by increasing the number of supports provided by the upper surface, and the assembly labor required for installation can be reduced.

FIG. 11 shows a schematic diagram of the size of the opening 25a of the fire extinguisher body 21 and the support 25 and the stability of the fixing of the fire extinguisher 20. In FIG.
The fire extinguisher body 21 is a container-like shape with a curved outer shape, and as shown in Fig. 11(c), making the opening 25a of the support 25 as small as possible (Θ>45 degrees) will make the so-called seating of the fire extinguisher body 21 on the support 25 more stable, but on the other hand, if the support 25 is small, the appearance will be poor. Also, as shown in Fig. 11(b), if the opening 25a of the support 25 is made large (Θ<45 degrees), the appearance will be improved, but the curvature will be large in the large outer shape part of the fire extinguisher body 21, making the seating unstable.
In this embodiment, as shown in Figure 11 (a), the size of the support 25 is set so that the angle Θ between the normal N at the contact point between the outer shape of the fire extinguisher main body 21 and the horizontal is approximately 45 degrees, thereby achieving a balance between the stability of the seating of the fire extinguisher main body 21 and good appearance.

FIG. 12 is a perspective view showing an example of a fastener, FIG. 13(a) is a schematic vertical cross-sectional view showing a fastening structure according to Modification 1 of the fire extinguisher 20, and FIG. 13(b) is a schematic plan view.
In the booth 1 of this embodiment, as shown in Figure 11 (a), a support 25 is placed on the upper surface 5a of the ceiling panel 5 so as to surround the opening 51 and support the fire extinguisher main body 21 from below in the direction of gravity, and a fixing device 26 is inserted into a part of the fire extinguisher main body 21 on the lower surface 5b of the ceiling panel 5 to fix the fire extinguisher main body 21 to the support device 25, and the fire extinguisher 20 may be fixed by sandwiching the ceiling panel 5 between the support device 25 and the fixing device 26.

As shown in FIG. 12, the fixing device 26 is connected to a part of the fire extinguisher body 21 and has a notch 26a formed in the plate-like body so as to straddle the fire extinguisher body 21, and has a spring part 26b that protrudes in a direction intersecting the connection direction and is connected to a part of the fire extinguisher body 21 on the underside 5b of the ceiling panel 5, thereby fixing the fire extinguisher body 21 to the support device 25.

As shown in FIG. 13, the fire extinguisher 20 is supported from below in the direction of gravity with a part of the fire extinguisher body 21, the extinguishing agent spray nozzle 22, and the heat detector 22b housed in the opening 25a of the support 25 fixed to the upper surface 5a of the ceiling panel 5 so as to surround the opening 51 of the ceiling panel 5. Then, the fixing device 26 is inserted into the stepped body 22a of the extinguishing agent spray nozzle 22 from the lower surface 5b side of the ceiling panel 5 (see arrow P in FIG. 13(b)), and the spring part 26b presses the lower surface 5b of the ceiling panel 5, and the fire extinguisher body 21 is supported and fixed at the upper end in a state in which it is pulled into the opening 25a of the support 25 by the reaction force (see arrow F in FIG. 13(a)). This allows the fire extinguisher 20 to be easily and detachably installed on the ceiling panel 5 of the booth 1.

Figure 14(a) is a spacer 26B as a fixing device, (b) is a diagram showing an E-type retaining ring 26A, Figure 15(a) is a schematic vertical cross-sectional view showing a fixing structure using the E-type retaining ring 26A of the fire extinguisher 20, and (b) is a schematic plan view.
The fire extinguisher 20 may be fixed using an E-type retaining ring 26A as a fixing device. Standardized E-type retaining rings 26A are available according to the shaft diameter. In this embodiment, the E-type retaining ring 26A is selected according to the shaft diameter of the stepped body 22a of the extinguishant spray nozzle 22, and the E-type retaining ring 26A can be inserted into the body 22a with a spacer 26B interposed between the E-type retaining ring 26A and the lower surface 5b of the ceiling panel 5 to fix the E-type retaining ring 26A.
As shown in FIG. 14( a ), the spacer 26B has a notch 26Ba formed in a plate-like body so as to straddle the body portion 22 a and is formed larger than the opening 51 so as to prevent the E-type retaining ring 26A from entering the opening 51.
As shown in FIG. 14(b), the E-type retaining ring 26A has spring properties so that it presses against the lower surface 5b of the ceiling panel 5 via the spacer 26B when it is twisted in the thickness direction and inserted into the body portion 22a.

As shown in Fig. 15(b), the E-type retaining ring 26A thus formed is inserted into the stepped body 22a of the extinguishing agent spray nozzle 22 from the underside 5b of the ceiling panel 5 via the spacer 26B (see arrow Q in Fig. 15(b)). The twisted portion 26Aa of the E-type retaining ring 26A presses against the underside 5b of the ceiling panel 5, and the fire extinguisher body 21 is supported and fixed at the upper end in a state in which it is pulled into the opening 25a of the support 25 by the reaction force (see arrow F in Fig. 15(a)). This allows the fire extinguisher 20 to be easily and detachably installed on the ceiling panel 5 of the booth 1.
