[0031] The following describes a private booth 1 according to one embodiment of the present invention, using Figures 1 to 8. In this embodiment, the direction of the private booth 1 is defined by the arrow in Figure 1. As shown in Figure 1, the private booth 1 according to this embodiment is placed on the floor and used for one person or a small number of people to use the room.

[0032] As shown in Figures 1 and 2, the private booth 1 according to this embodiment comprises a peripheral wall 2 with an opening 2a formed on its side (the front side in this embodiment), a door 3 provided on the peripheral wall 2 so as to be able to open and close the opening 2a, a plurality of (four in this embodiment) casters 26, and a plurality of (four in this embodiment) grounding members 27 whose extension length relative to the floor surface can be adjusted. A ceiling 51 is provided at the upper end of the peripheral wall 2. As shown in Figure 4, the peripheral wall 2 is provided with panel bodies on both the left and right sides and the rear. When the front opening 2a in the peripheral wall 2 is closed by the door 3, an internal space isolated from the outside is formed in the private booth 1.

[0033] The peripheral wall 2 comprises a base frame 21 and a plurality of panel bodies fixed to the base frame 21 by screwing, welding, or adhesive bonding. The base frame 21 is a frame structure formed in a rectangular shape in plan view by combining metal square tubes. In this embodiment, the base frame is constructed by combining a support frame 22, a support column 23, a ceiling frame 24, etc., as shown in Figure 5.

[0034] The support frame 22 is provided at the lower end of the base frame 21. In this embodiment, the support frame 22 is arranged along the front-rear direction on both the left and right sides of the base frame 21. An insertion hole 22a is opened in the center of the left support frame 22 in the front-rear direction, and the support frame 22 penetrates through the support frame 22 in the vertical direction.

[0035] Four support columns 23 are provided at both the front and rear ends of the support frame 22, extending vertically. An auxiliary frame 23a is fixed to each support column 23 on its inner side in the front-to-back direction. Multiple engagement holes 23b are opened along the longitudinal direction on both the left and right sides of the auxiliary frame 23a.

[0036] The upper ends of the four support columns 23 are connected by four ceiling frames 24. In this embodiment, the ceiling frame 24 located on the front side of the base frame 21 and the ceiling frame 24 located on the rear side are connected at their intermediate points by two reinforcing frames 24a.

[0037] As shown in Figures 1 to 4, the base frame 21 is fitted with an outer panel 41, an inner upper panel 42T, an inner middle panel 42M, an inner lower panel 42B, an outer panel 43, an inner upper panel 44T, an inner middle panel 44M, an inner lower panel 44B, and a rear panel 45 as panel bodies. In this way, the private room type booth 1 according to this embodiment has a simple configuration in which the peripheral wall 2 is made up of the base frame 21 and a plurality of panel bodies.

[0038] As shown in Figures 3 and 6, an outer panel 41, which is a metal plate exposed to the outside of the peripheral wall 2, is assembled to the left outer surface of the base frame 21. In addition, an inner upper panel 42T, an inner middle panel 42M, and an inner lower panel 42B are assembled to the left inner surface of the base frame 21, from top to bottom, exposed to the inside of the peripheral wall 2. In this embodiment, a switch 42s is provided at the front end of the inner middle panel 42M.

[0039] Furthermore, as shown in Figure 3, an outer panel 43, which is a metal plate exposed to the outside of the peripheral wall 2, is assembled to the right outer surface of the base frame 21. Also, on the right inner surface of the base frame 21, the inner upper panel 44T, inner middle panel 44M, and inner lower panel 44B are assembled from top to bottom, exposed to the inside of the peripheral wall 2. In this embodiment, sound-absorbing materials such as nonwoven fabric are used for the panels 42T, 42M, 42B, 44T, 44M, and 44B provided on the inner circumferential surface of the peripheral wall 2.

[0040] As shown in Figures 3 and 4, a rear panel body 45 is provided on the rear side of the base frame 21. The rear panel body 45 consists of a glass frame 45a and a glass panel 45b supported by the glass frame 45a. It is also possible to use a metal panel similar to those on the left and right sides instead of a glass panel for the panel body provided on the rear side of the base frame 21.

[0041] As shown in Figures 1, 2, and 4, a door 3 is provided on the front side of the base frame 21 via a hinge H. The door 3 consists of a door frame 31 and a door panel 32, which is a glass panel supported by the door frame 31. A doorknob 33 is provided on the door 3. In the private booth 1 according to this embodiment, the door 3 is rotatably assembled to the base frame 21, so that the opening 2a in the peripheral wall 2 can be opened and closed by the door 3.

[0042] As shown in Figures 2 to 4, in the private booth 1 according to this embodiment, the support frame 22 of the base frame 21 is provided with casters 26 and grounding members 27. In this embodiment, four casters 26 and four grounding members 27 are provided adjacent to each other. The grounding members 27 can be adjusted in length by the user rotating them with their hands or tools, thereby adjusting the extension length from the lower surface of the support frame 22 to the floor.

[0043] In this embodiment, the private booth 1 can be switched between an immovable state in which the casters 26 are lifted away from the floor and a movable state in which the casters 26 are in contact with the floor. Specifically, as shown in Figure 8(a), the casters 26 are made immovable by adjusting the extension length of the ground contact member 27 from the lower surface of the support frame 22 to be greater than the extension length of the casters 26. Also, as shown in Figure 8(b), the casters 26 are made movable by adjusting the extension length of the ground contact member 27 from the lower surface of the support frame 22 to be less than the extension length of the casters 26.

[0044] In this embodiment, four casters 26 are provided on the individual booth 1, but the number of casters 26 is not limited as long as the individual booth 1 can be moved. Similarly, the number of grounding members 27 is not limited as long as the individual booth 1 can be stably installed. However, in order to ensure that the casters 26 are reliably separated from the floor surface when the booth is immobile, it is preferable to have the same number of casters 26 as the number of grounding members 27, and to position the casters 26 in the vicinity of the grounding members 27.

[0045] In the private booth 1 according to this embodiment, the area around the support frame 22 of the base frame 21 is formed as a storage space. Specifically, as shown in Figure 6, a power strip T is housed in the storage space formed below the support frame 22. Wiring cords and the like (not shown) are also housed in the storage space.

[0046] Furthermore, a cover member 25 is provided on the inner circumferential surface of the lower end of the base frame 21, and this storage space (the power strip T, wiring cords, etc. housed in the storage space) is covered by the cover member 25. In this way, in the private booth type 1, by covering the storage space containing the wiring cords, etc. with the cover member 25, it is possible to prevent the wiring cords, etc. from being exposed inside the private booth type 1. It is also possible to utilize the upper part of the support frame 22 as a storage space.

[0047] Furthermore, as shown in Figures 3 and 4, a gap is formed between the outer panel 41 and the inner panels (inner upper panel 42T, inner middle panel 42M, and inner lower panel 42B) in the private booth 1. Through-holes 22a are opened in the support frame 22, allowing this gap to communicate with the storage space formed below the support frame 22. In this way, in the private booth 1, wiring cords and the like can be guided from the gap between the outer panel 41 and the inner panels through the through-holes 22a to the storage space, thus preventing the exposure of wiring cords and the like inside the private booth 1.

[0048] Furthermore, as shown in Figures 2 and 3, a fire extinguisher 52 and a light 53 are provided on the ceiling 51 of the private booth 1. The light 53 can be switched on and off by the user of the private booth 1 operating a switch 42s provided on the inner panel 42M. The fire extinguisher 52 includes a detection unit 52a that detects the occurrence of a fire, and a discharge unit 52c that automatically sprays the fire extinguishing agent filled in the tank unit 52b when the detection unit 52a detects the occurrence of a fire.

[0049] Thus, in the private booth 1 according to this embodiment, the ceiling 51 enhances the sound insulation performance of the private booth 1, and also enables automatic fire extinguishing inside the private booth 1 in the event of a fire.

[0050] Furthermore, as shown in Figures 6 and 7, joints are formed between the support columns 23 constituting the base frame 21 and the inner panels (inner upper panel 42T, inner middle panel 42M, and inner lower panel 42B), and an auxiliary frame 23a is provided in these joints. The auxiliary frame 23a has numerous engagement holes 23b opening along its longitudinal direction, which allow engagement members to be engaged.

[0051] In the private booth 1 according to this embodiment, a top plate 61 and a hook member 62 are used as engaging members. As shown in Figure 7, the engaging members, the top plate 61 and the hook member 62, are assembled to the left inner surface of the peripheral wall 2 by engaging the engaging portion 61a formed on the top plate 61 and the engaging portion 62a formed on the hook member 62 with the engaging hole 23b. In this embodiment, as shown in Figures 2 and 3, a hook member 62, which is an engaging member, is also assembled to the right inner surface of the peripheral wall 2.

[0052] Thus, in the private booth 1, the engaging members such as the top plate 61 can be attached to and detached at any height position inside the private booth 1. In addition to the top plate 61 and hook members 62, display stands, lighting fixtures, speakers, telephones, etc. can also be used as engaging members.

[0053] In the private booth 1 according to this embodiment, as shown in Figure 2, the inner surfaces of the surrounding wall 2 and door 3 are formed to open downwards. By forming the private booth 1 with an opening at the bottom without a floor plate, as described above, it is possible to secure a larger effective height inside the room relative to the overall height of the booth compared to a booth with a floor plate. When mass-producing the private booth 1, it is necessary to be able to install them in many spaces, and there is a limit to how high the overall height of the private booth 1 can be made. Therefore, the configuration of this embodiment, which allows for the maximum possible height inside the room, is preferable.

[0054] Furthermore, the lower end of the peripheral wall 2, that is, the lower end of the base frame 21, is formed with an open side facing the opening 2a. Therefore, users do not need to climb or descend any steps when entering or exiting the private booth 1. In this way, the private booth 1 in this embodiment improves the convenience of the private booth 1 by eliminating the step between the outside and the inside, making it possible to enter and exit the private booth 1 on the same plane.

[0055] In the private booth 1 according to this embodiment, the inner surfaces of the surrounding walls 2 and door 3 are formed to open downwards, and no floor member is provided below the surrounding walls 2 and door 3. Therefore, when using the private booth 1, the floor member will not deform or make any noise due to the weight of the user or other factors. Furthermore, in this embodiment, since there is no need to provide a highly rigid floor member to prevent deformation, the manufacturing cost of the private booth 1 can be reduced.

[0056] In addition, in the individual booth 1, as shown in the modified example in Figure 9(a), the ends of the base frame 21 on the side of the opening 2a (the lower ends of the support columns 23) are connected to each other by a plate member 71 that contacts the floor surface. As shown in Figure 9(b), the plate member 71 is a plate-shaped member with fixing parts 71b formed at both ends of the plate portion 71a. With the plate portion 71a of the plate member 71 in contact with the floor surface, the fixing parts 71b are fixed to the support columns 23 on both the left and right sides with fasteners such as screws, thereby assembling the plate member 71 to the peripheral wall 2. In this configuration, since the plate member 71 is installed in a state where it is in contact with the floor surface after the height adjustment of the grounding member 27, it is always in contact with the floor surface when the individual booth 1 is in use.

[0057] As described above, by assembling the plate member 71 to the base frame 21, the peripheral wall 2 can be reinforced and the stability of the individual booth 1 can be improved. In this configuration, it is desirable to keep the height gap between the floor surface and the upper surface of the plate portion 71a to 5 mm or less, so that there is virtually no step, in order to prevent tripping. Therefore, it is preferable to make the thickness of the plate portion 71a 5 mm or less. Taking into account construction errors, it is even preferable to make the thickness of the plate portion 71a 3 mm or less.

[0058] Thus, in this modified example, even in the private booth 1, by reducing the difference in height between the outside and the inside, it is possible to enter and exit the private booth 1 on almost the same plane, thereby improving the convenience of the private booth 1.

[0059] As described above, in this specification, if a plate-like member is provided on the base frame 21 that does not require the user to climb up or down or climb over any steps when entering or exiting the private booth 1, then it is considered that "the side of the opening 2a at the lower end of the base frame 21 is open."

[0060] Furthermore, in this modified example, it is also possible to change the shape of the plate portion 71a of the plate member 71. For example, it is possible to widen the front-to-back width of the plate portion 71a in the forward direction, backward direction, or both directions. If the front-to-back width of the plate portion 71a is widened backward, it is possible to position the rear end of the plate portion 71a in the middle or rear end of the internal space of the private booth 1.

[0061] When the rear end of the plate portion 71a is positioned at the rear end of the internal space of the private booth 1, the plate portion 71a covers almost the entire area inside the peripheral wall 2 and door 3 in the private booth 1. Thus, in this modified version of the private booth 1, it is also possible to configure the interior of the peripheral wall 2 and door 3 to be open downwards, and the floor surface exposed in the opening portion to be covered with the plate portion 71a of the plate member 71. Even in this case, the plate portion 71a is not a floor member spaced apart from the floor surface, but is positioned in contact with the floor surface so as to overlap it, so no abnormal noises such as creaking, bending, or rattling will occur in the plate portion 71a.

[0062] Next, a private booth 101 according to another embodiment of the present invention will be described using Figures 10 to 18. In this embodiment, the direction of the private booth 101 is defined by the arrow in Figure 10.

[0063] As shown in Figures 10 and 11, the private booth 101 according to this embodiment includes a perimeter wall 102 with an opening 102a formed on its side (the front side in this embodiment), a door 103 provided on the perimeter wall 102 so as to be able to open and close the opening 102a, a plurality of (four in this embodiment) casters 126, and a plurality of (four in this embodiment) grounding members 127 whose extension length relative to the floor surface can be adjusted. A ceiling 151 is provided at the upper end of the perimeter wall 102. As shown in Figure 13, the perimeter wall 102 is provided with panel bodies on both the left and right sides and the rear. When the front opening 102a of the perimeter wall 102 is closed by the door 103, an internal space isolated from the outside is formed in the private booth 101.

[0064] The peripheral wall 102 comprises a base frame 121 and a plurality of panel bodies fixed to the base frame 121 by screwing, welding, or adhesive bonding. The base frame 121 is a frame structure formed in a rectangular shape in plan view by combining metal square tubes. In this embodiment, the base frame 121 is constructed by combining a base member 122, a front frame 123, a rear frame 124, connecting members 125, 125, etc., as shown in Figures 14 and 15.

[0065] The base member 122 constitutes the lower end of the base frame 121. In this embodiment, the base member 122 is open on the front side, which is the side of the opening 102a, while the other side, the rear side and both the left and right sides, are closed, forming a U-shape in plan view. Thus, according to the private booth 101 of this embodiment, the base member 122 that constitutes the lower end of the base frame 121 is configured to be open only on the side of the opening 102a. This makes it possible to stabilize the shape of the base frame 121, and thus maintain a high level of strength in the private booth 101.

[0066] In the private booth 101 according to this embodiment, as shown in Figure 11, the inner sides of the peripheral wall 102 and door 103 are formed to open downwards. Furthermore, the lower end of the peripheral wall 102, that is, the base member 122 which constitutes the lower end of the base frame 121, is formed to be open on the side of the opening 102a as described above. Therefore, there is no need for the user to climb or descend a step when entering or exiting the private booth 101. In this way, the private booth 101 in this embodiment improves the convenience of the private booth 101 by eliminating the step between the outside and the inside, making it possible to enter and exit the private booth 101 on the same plane.

[0067] In the base member 122, side portions 122a and 122a are provided on both the left and right sides, and the rear ends of the side portions 122a and 122a are connected by a rear portion 12b. A front frame support portion 122c is formed at the front end of each side portion 122a. In addition, rear frame support portions 122d are formed at both the left and right ends of the rear portion 122b.

[0068] A front frame 123, which is formed in a gate shape when viewed from the front, is erected on the front frame support portions 122c, 122c of the base member 122. The front frame 123 is formed by connecting the upper ends of two front support columns 123a, 123a with a front connecting portion 123b. Multiple engagement holes 123c are opened along the longitudinal direction on the inner surface of the front support column 123a, allowing engagement members to be engaged.

[0069] A rear frame 124, which is formed in a gate shape when viewed from the front, is erected on the rear frame support portions 122d, 122d of the base member 122. The rear frame 124 is formed by connecting the upper ends of two rear support columns 124a, 124a with a rear connecting portion 124b. Multiple engagement holes 124c are opened along the longitudinal direction on the inner surface of the rear support column 124a, allowing engagement of an engaging member.

[0070] In both the front frame 123 and the rear frame 124, the upper ends of adjacent front support columns 123a and rear support columns 124a are connected by connecting members 125 and 125. In this way, the base member 122, front frame 123, rear frame 124, and connecting members 125 and 125 are combined to form a highly rigid base frame 121.

[0071] As shown in Figures 10 to 13, the base frame 121 is fitted with a reinforcing panel 140, an outer panel 141, an inner upper panel 142T, an inner lower panel 142B, an outer panel 143, an inner upper panel 144T, an inner lower panel 144B, and a rear panel 145 as panel bodies. In this way, the private room type booth 101 according to this embodiment has a simple configuration in which the peripheral wall 102 is made up of the base frame 121 and the multiple panel bodies.

[0072] As shown in Figures 12, 13, and 16, reinforcing panels 140 are provided on both the left and right sides of the base frame 121, above the side portions 122a of the base member 122, between the front support column 123a and the rear support column 124a. High-rigidity honeycomb panels are used for the reinforcing panels 140. It is also possible to use other high-rigidity panels such as resin panels or carbon panels as reinforcing panels.

[0073] In the private booth 101 according to this embodiment, by employing a highly rigid reinforcing panel 140 as part of the panel body constituting the peripheral wall 102, the strength of the peripheral wall 102 in the private booth 101 can be maintained at a high level. Specifically, by constructing the peripheral wall 102 using the reinforcing panel 140, the rigidity of the private booth 101 is increased, and deformation of the peripheral wall 102 can be suppressed even when the peripheral wall 102 is formed in a U-shape in plan view. For this reason, even in the configuration without the plate member 71 in the first embodiment, the private booth 101 can maintain high stability. It should be noted that the structure that provides rigidity using the reinforcing panel 140 is not limited to booths without floors as in the present invention, but is a structure that can be used in general.

[0074] Furthermore, in the private booth 101 according to this embodiment, the reinforcing panel 140 is provided between the front support column 123a and the rear support column 124a. That is, even if the reinforcing panel 140 is provided, the surrounding wall 102 does not become thicker, so the external dimensions of the private booth 101 do not increase, nor does the internal space of the private booth 101 decrease.

[0075] The reinforcing panel 140 is assembled to the base frame 121 via a panel support member 129 fixed to the side portion 122a of the base member 122. It is also possible to assemble the reinforcing panel 140 to the front support column 123a and the rear support column 124a, or to assemble it to the side portion 122a, the front support column 123a, and the rear support column 124a. Multiple magnets 140a are fixed to the inner surface of the reinforcing panel 140 to attract the inner upper panel 142T, the inner lower panel 142B, the inner upper panel 144T, and the inner lower panel 144B (hereinafter collectively referred to as "inner panels").

[0076] As shown in Figures 12 and 13, an outer panel 141, which is a metal plate exposed to the outside of the peripheral wall 102, is assembled to the outside of the right reinforcing panel 140 on the base frame 121. On the inside of the right reinforcing panel 140, the inner upper panel 142T and the inner lower panel 142B are assembled from top to bottom, exposed to the inside of the peripheral wall 102, via a magnet 140a. In this embodiment, a switch 142s is provided at the front end of the inner upper panel 142T.

[0077] As shown in Figures 12 and 13, on the base frame 121, an outer panel 143, which is a metal plate exposed to the outside of the peripheral wall 102, is assembled to the outside of the left reinforcing panel 140. Also, on the outside of the left reinforcing panel 140, from top to bottom, the inner upper panel 144T and the inner lower panel 144B are attached via magnets 140a, exposed to the inside of the peripheral wall 102.

[0078] As described above, in the private booth 101 according to this embodiment, the appearance of the exterior is improved by providing outer panels 141 and 143 on the outside of the reinforcing panel 140. In addition, in this embodiment, the inner panel is made by compressing sound-absorbing material such as nonwoven fabric. In this way, by providing the inner panel on the inside of the reinforcing panel 140, it is possible to improve the appearance and sound absorption inside the private booth 101.

[0079] As shown in Figures 12 and 13, a rear panel body 145 is provided on the rear side of the base frame 121. The rear panel body 145 consists of a glass frame 145a and a glass panel 145b supported by the glass frame 145a. It is also possible to use a metal panel similar to those on the left and right sides instead of a glass panel for the panel body provided on the rear side of the base frame 121. In this case, a reinforcing panel 140 may also be provided on the rear side of the base frame 121.

[0080] As shown in Figures 10, 11, and 13, a door 103 is provided on the front side of the base frame 121 via a hinge H. The door 103 consists of a door frame 131 and a door panel 132, which is a glass panel supported by the door frame 131. A handle 133 is provided on the door 103. In the private booth 101 according to this embodiment, the door 103 is rotatably assembled to the base frame 121, so that the opening 102a in the peripheral wall 102 can be opened and closed by the door 103.

[0081] As shown in Figures 11 to 13, in the private booth 101 according to this embodiment, casters 126 and grounding members 127 are provided on the lower surface of the base member 122. In this embodiment, four casters 126 and four grounding members 127 are provided adjacent to each other. The extension length of the grounding members 127 from the lower surface of the base member 122 to the floor can be adjusted by the user rotating them with their hands or tools.

[0082] In this embodiment, the private booth 101 can be switched between an immovable state in which the casters 126 are lifted away from the floor and a movable state in which the casters 126 are in contact with the floor. Specifically, as shown in Figure 18(a), the casters 126 are made immovable by adjusting the extension length of the grounding member 127 from the lower surface of the base member 122 to be greater than the extension length of the casters 126. Also, as shown in Figure 18(b), the casters 126 are made movable by adjusting the extension length of the grounding member 127 from the lower surface of the base member 122 to be less than the extension length of the casters 126.

[0083] In the private booth 101 according to this embodiment, as shown in Figures 18(a) and (b), the grounding member 127 has a grounding cover 127b attached to the lower surface of the grounding leg portion 127a by an adhesive member such as double-sided tape. The grounding cover 127b is a resin member formed with a smooth curved shape on its lower surface.

[0084] In this embodiment, as described above, by providing a ground cover 127b on the lower surface of the grounding member 127, the sliding ability on the floor surface can be improved. Therefore, when the individual booth 101 is immobilized and subjected to an impact such as an earthquake, the grounding member 127 is more likely to remain in place without following the displacement of the floor surface. This reduces the possibility of the individual booth 101 tipping over when subjected to an impact. Furthermore, by making the lower surface of the ground cover 127b a smooth curved shape, it is possible to suppress snagging on the floor surface (making it easier to slide on the floor surface) and further reduce the possibility of the individual booth 101 tipping over.

[0085] It should be noted that, with a configuration different from the grounding member 127 in this embodiment, a means of preventing tipping over by grounding the individual booth 101 with a large plate-like object to improve sliding is also conceivable. However, if the grounding area of ​​the individual booth 101 is made too large, the booth may slide and move, for example when the door is opened or closed, or when someone unexpectedly leans against it. Furthermore, the process of switching the individual booth 101 from an immovable state to a movable state becomes complicated. On the other hand, with the grounding member 127 in this embodiment, the grounding area of ​​the individual booth 101 does not become too large, so the individual booth 101 will not slide and move when someone leans against it. In addition, the process of switching the individual booth 101 from an immovable state to a movable state can be easily performed.

[0086] Furthermore, according to the grounding member 127 of this embodiment, since a smooth grounding cover 127b is provided, when making fine adjustments to the location where the individual booth 101 is installed, the individual booth 101 can be moved by sliding it on the floor surface by applying force to push it. In other words, according to this embodiment, it is preferable that the casters 126 are not required to be grounded when making fine adjustments to the installation location. It should be noted that the structure that prevents tipping and enables fine adjustments by the grounding cover 127b is a general-purpose structure that can be used not only for booths without floors as in the present invention.

[0087] In this embodiment, four casters 126 are provided on the individual booth 101, but the number of casters 126 is not limited as long as the individual booth 101 can be moved. Similarly, the number of grounding members 127 is not limited as long as the individual booth 101 can be stably installed. However, in order to ensure that the casters 126 are reliably separated from the floor surface when the booth is immobile, it is preferable to have the same number of casters 126 as the number of grounding members 127, and to position the casters 126 in the vicinity of the grounding members 127.

[0088] In the private booth 101 according to this embodiment, the area below the base member 122 of the base frame 121 is formed as a storage space. Furthermore, a cover member 128 is provided on the inner circumferential surface of the base member 122, and the storage space below the base member 122 and the contents inside are covered by the cover member 128. In this way, in the private booth 1, by covering the storage space containing contents such as wiring cords with the cover member 128, it is possible to prevent wiring cords and the like from being exposed to the inside of the private booth 1.

[0089] Furthermore, as shown in Figures 12 and 13, a gap is formed around the magnet 140a between the reinforcing panel 140 and the inner panel in the private booth 101. In this way, in the private booth 101, wiring cords and the like can be housed in the gap between the reinforcing panel 140 and the inner panel, thus preventing wiring cords and the like from being exposed on the inside of the private booth 101.

[0090] Furthermore, as shown in Figures 11 and 12, a fire extinguisher 152 and a light 153 are provided on the ceiling 151 of the private booth 101. The light 153 can be switched on and off by the user of the private booth 101 by operating a switch 142s provided on the inner upper panel 142T. The fire extinguisher 152 includes a detection unit 152a that detects the occurrence of a fire, and a discharge unit 152c that automatically sprays the fire extinguishing agent filled in the tank unit 152b when the detection unit 152a detects the occurrence of a fire.

[0091] Thus, in the private booth 101 according to this embodiment, the ceiling 151 enhances the sound insulation performance of the private booth 101, and also enables automatic fire extinguishing inside the private booth 101 in the event of a fire.

[0092] Furthermore, as shown in Figure 17, the front support column 123a and the rear support column 124a constituting the base frame 121 have a plurality of engagement holes 123c and 124c that can be engaged with the engaging member, opening along the longitudinal direction. In the private room type booth 101 according to this embodiment, a top plate 161 and a display 173 are used as the engaging member. As shown in Figure 17, the top plate 61, which is the engaging member, is assembled to the inner surface on the right side of the peripheral wall 102 by engaging the engagement portion 161a formed on the bracket for assembling the top plate 161 with the engagement holes 123c and 124c.

[0093] Furthermore, as shown in Figure 17, the display 173 is assembled to the base frame 121 via the display support frame 171, the locking member 171a, and the display support member 172. Specifically, as shown in Figure 17, the display support frame 171 and the locking member 171a are assembled to the display support member 172 to which the display 173 is assembled. Then, by engaging the locking member 171a with the engagement holes 123c and 124c, the display 173, which is the engaging member, is assembled to the inner surface on the right side of the peripheral wall 102.

[0094] Thus, in the private booth 101, the engaging members such as the top plate 161 and the display 173 can be attached to and detached at any height position inside the private booth 101. In addition to the top plate 161 and the display 173, lighting fixtures, speakers, telephones, etc. can also be used as engaging members.

[0095] In the private booth 101 according to this embodiment, the inner surfaces of the peripheral wall 102 and door 103 are formed to open downwards, and no floor member is provided below the peripheral wall 102 and door 103. Therefore, when using the private booth 101, the floor member will not deform or make any noise due to the weight of the user or other factors. Furthermore, in this embodiment, there is no need to provide a highly rigid floor member to prevent deformation, so the manufacturing cost of the private booth 101 can be reduced.

[0096] [Other variations] The embodiments described above can be modified as appropriate, as shown in the other modifications described below. Each modification described herein may be applied in combination with other modifications, to the extent that it does not create inconsistencies.

[0097] The surrounding walls of the private booth can also be constructed by connecting multiple panel bodies without a base frame, rather than by assembling a base frame and multiple panel bodies as in this embodiment.

[0098] The base frame that defines the external shape of the private booth can have a shape other than a rectangle when viewed from above. For example, the base frame can have a circular, triangular, pentagonal, trapezoidal, or other shape when viewed from above.

[0099] The lower end of the base frame constituting the private booth only needs to be formed with an open side, at least on the side where the door is installed. In other words, the lower end of the base frame can be configured so that the part other than the opening is closed.

[0100] Furthermore, the materials constituting the panel body and door are not limited to glass panels or metal panels; materials such as wood or resin can also be used. Additionally, arrangements other than those in this embodiment are also possible.

[0101] In a private booth, it is possible to open engagement holes in the support columns for engaging the engaging members. Furthermore, it is also possible to have a private booth without a ceiling. If a ceiling is provided in the private booth, it is also possible to omit fire extinguishers or similar equipment from the ceiling. [Explanation of Symbols]
