[Modes for carrying out the invention]

[0026] [Private Booth 1 (First Embodiment)] The following describes a private booth 1 according to the first embodiment of the present invention, using Figures 1 to 8. In this embodiment, the direction of the private booth 1 is defined by the arrows 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. The private booth 1 according to this embodiment has a width dimension of 1200 mm in the left-right direction and a width dimension of 1200 mm in the front-back direction.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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."

[0055] 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.

[0056] 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.

[0057] [Private Booth 101 (Second Embodiment)] Next, a private booth 101 according to the second embodiment of the present invention will be described with reference to Figures 10 to 16. In this embodiment, the direction of the private booth 101 is defined by the arrow in Figure 10. The private booth 101 according to this embodiment is suitable for use by wheelchair users or by multiple people when placed on the floor, as shown in Figure 13. The private booth 101 according to this embodiment has a width dimension of 2000 mm in the left-right direction and a width dimension of 1600 mm in the front-back direction.

[0058] When a wheelchair user uses the private booth 101, it is preferable to provide a retraction space in the corner of the private booth 101 where a permanent chair C can be placed, as shown by the dashed line in Figure 13. Furthermore, when a retraction space for chair C is provided within the private booth 101, it is also preferable to mark the area of ​​the retraction space on the floor. Alternatively, the space beneath the top panel 161 of the private booth 101 can also be used as a retraction space for chair C.

[0059] As shown in Figures 10 to 13, the private booth 101 according to this embodiment includes a peripheral wall 102 with an opening 102a formed on its side (the front side in this embodiment), a door 103 provided on the peripheral wall 102 so as to be able to open and close the opening 102a, a plurality of casters 126, and a plurality of 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 peripheral wall 102.

[0060] As shown in Figures 10 to 13, the peripheral wall 102 is equipped with panel bodies on both the left and right sides, the rear, and the left side of the front. When the opening 102a on the front right side of the peripheral wall 102 is closed by the door 103, an internal space isolated from the outside is formed in the private booth 101.

[0061] 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 support frame 122, a support column 123, a ceiling frame 124, a side panel frame 128, etc., as shown in Figure 15.

[0062] The support frame 122 is provided at the lower end of the base frame 121. In this embodiment, the support frame 122 is located on both the left and right sides, the rear side, and the front left side of the base frame 121. Four support columns 123 are provided at the ends of the support frame 122, erected vertically. The upper ends of the left and right pairs of support columns 123 are connected by a ceiling frame 124 at the construction site. Between the right end of the support frame 122 located on the front left side and the ceiling frame 124, a sleeve panel frame 128 is provided, erected vertically.

[0063] The support frame 122 may be constructed as a single unit or as a series of separate parts. However, considering the size required to fit into a transport elevator, it is preferable for transportation purposes to divide the entire structure into several parts and integrate multiple sections. When the support frame 122 is constructed as a series of separate parts, it is preferable to connect a U-shaped frame body, which connects the front left section to the left side and the middle section of the rear, with an L-shaped frame body, which connects the remaining middle section of the rear to the right side, using connecting members (members inserted into square tubes).

The automatic opening and closing device 109 is a commercially available electric door opening and closing device and, as shown in Figure 14(a), comprises an operating unit 191, a power supply unit 192 equipped with an adapter and connector, and a cord 193 that electrically connects these. The operating unit 191 is fixed to the door 103 and is rotatably connected to the ceiling frame 124 of the base frame 121 via an arm 191a and a link 191b.

[0071] The operating unit 191 houses a drive shaft that rotates around a vertical axis and a motor that rotates the drive shaft. The base end of the arm 191a is connected to the upper end of the drive shaft. The arm 191a rotates integrally with the drive shaft around the drive shaft. The base end of the link 191b is fixed to the ceiling frame 124, and the tip of the link 191b is rotatably connected to the tip of the arm 191a. The operating unit 191 also houses a control unit that controls the operation of the automatic opening and closing device 109.

[0072] The automatic opening and closing device 109 is equipped with an opening detection unit that detects the user's opening operation. When the opening detection unit of the automatic opening and closing device 109 detects the user's opening operation of the door 103 (the initial movement of the rotational displacement of the door 103), the control unit of the automatic opening and closing device 109 controls the motor in the operating unit 191 to rotate the drive shaft in one direction. As the motor in the operating unit 191 rotates the drive shaft, the arm 191a rotates relative to the link 191b, and the door 103 rotates in the direction of opening relative to the base frame 121. In other words, the automatic opening and closing device 109 performs the remaining rotational operation of the door 103 when it detects the initial movement of the rotational displacement of the door 103 by the user.

[0073] As described above, in the private booth 101 according to this embodiment, the automatic opening and closing device 109 automatically opens the door 103 when it detects the user's opening operation, making it easy for users (especially wheelchair users) to enter and exit.

[0074] The control unit of the automatic opening and closing device 109 controls the motor in the operating unit 191 to rotate the drive shaft in the reverse direction when a predetermined time has elapsed since the door 103 was opened. As the motor in the operating unit 191 rotates the drive shaft, the arm 191a rotates relative to the link 191b, causing the door 103 to rotate in a direction that closes relative to the base frame 121.

[0075] As described above, in the private booth 101 according to this embodiment, the automatic opening and closing device 109 automatically closes the door 103 after a predetermined time has elapsed since opening, so that the user (especially wheelchair users) does not need to close the door 103, making it easier to enter and exit.

[0076] In this embodiment, the control unit of the automatic opening / closing device 109 is equipped with a function to stop the opening and closing of the door 103 if the operation of the door 103 is obstructed during the opening and closing operation of the door 103. This prevents the user from being caught in the door 103 and allows for safe entry and exit from the private booth 101. However, the automatic opening / closing device 109 may also be configured without the above-mentioned stopping function.

[0077] In this embodiment, the control unit of the automatic opening / closing device 109 controls the motor to automatically close the door if the door 103 stops during the opening operation. Furthermore, if the door 103 stops during the closing operation, the control unit of the automatic opening / closing device 109 controls the motor to return to the open position, and then close the door again after a predetermined time has elapsed. Additionally, to maintain the open position, the motor controls the motor to stop in the open position after being stopped in the open position for a certain period of time.

[0078] It is also possible to configure the open detection unit in the private booth 101 in other ways. In this case as well, when the open detection unit detects an opening operation by the user, the automatic opening / closing device 109 will open the door 103. Possible configurations for the open detection unit include a sensor installed on the handle 133 of the door 103, or a switch, IC card sensor, or personal authentication sensor (facial recognition, fingerprint recognition, voiceprint recognition, etc.) installed on the door 103 or the side panel 134.

[0079] As shown in Figure 14(b), in this embodiment, a ceiling panel 147 is provided below the ceiling 151. The power supply unit 192, including adapters and connectors, and the wiring connected to the power supply unit 192 are housed in the space above the ceiling panel 147.

[0080] As described above, in this embodiment, the power supply unit 192 is housed in the space above the ceiling panel 147, in a location that is not visible from the outside. This prevents the wiring of the automatic opening and closing device 109 from being exposed inside the private booth 101, thereby improving the aesthetic appearance of the private booth 101. As shown in Figure 14(b), the wiring connecting the operating unit 191 and the power supply unit 192 is inserted into the gap between the end of the ceiling panel 147 and the ceiling frame 124.

[0081] As shown in the modified example of this embodiment in Figure 16, it is also possible to provide power supply fittings 135a and 135b on the door 103 and the base frame 121, respectively, and to route the wiring between the operating unit 191 and the power supply unit 192 through the power supply fittings 135a and 135b. This makes it possible to prevent the wiring between the operating unit 191 and the power supply unit 192 from being exposed inside the private booth 101.

[0082] As shown in Figure 12, in the private booth 101 according to this embodiment, the support frame 122 of the base frame 121 is provided with casters 126 and grounding members 127. In this embodiment, the casters 126 and grounding members 127 are provided adjacent to each other. The grounding members 127 can be rotated by the user using their hands or tools to adjust the extension length from the lower surface of the support frame 122 to the floor.

[0083] In the private booth 101 according to this embodiment, the casters 126 can be switched between an immovable state where they are lifted off the floor and a movable state where they are in contact with the floor. In other words, the private booth 101 according to this embodiment can be easily moved and installed.

[0084] As shown in Figure 13, in the private booth 101 according to this embodiment, a top plate 161 that moves up and down along the left peripheral wall 102 is provided on the inner surface of the left peripheral wall 102. By configuring the top plate 161 to be able to move up and down, desk work inside the private booth 101 is made easier. A handgrip portion 161a is formed at the lower part of the front edge of the top plate 161 so that wheelchair users can grab onto it when changing their posture, etc. Alternatively, a recess may be formed at the lower part of the front edge of the top plate 161 to allow a hand to be grabbed. As described above, by providing the handgrip portion 161a, not only wheelchair users but also able-bodied people can grab onto the top plate 161 when approaching it while sitting in a chair, thus improving convenience.

[0085] Furthermore, as shown in Figure 16, the individual booth 101 is provided with a pair of left and right actuators 162-162, which are lifting units for raising and lowering the top plate 161. The actuators 162-162 are housed inside the peripheral wall 102 and covered by an inner panel 142M so as not to be exposed on the inner surface of the left peripheral wall 102.

[0086] In this embodiment, each actuator 162 is equipped with a support portion 163 that extends laterally from the main body and slides in the longitudinal direction (vertical direction) of the main body, as shown in Figures 12 and 13. The top plate 161 is fixed to the support portion 163 via a bracket 164. The pair of actuators 162-162 are controlled by an electrically connected control unit 165 to raise and lower their respective support portions 163 in synchronous motion. As a result, the top plate 161 can be raised and lowered while maintaining a horizontal position.

[0087] As shown in Figure 10, the support portion 163 of the actuator 162 extends into the interior of the private booth 101 through the slit S between the inner panels 142M and 142M. As the support portion 163 moves up and down through the slit S, the top plate 161 moves up and down.

[0088] Thus, in this embodiment, the actuators 162-162 are covered with the inner panel 142M, and the support portion 163 extends through the slit S, so that the actuators 162-162 are not exposed in the internal space of the private booth 101. This enhances the aesthetic appeal of the private booth 101. Furthermore, since the actuators 162-162 are not present in the internal space of the private booth 101 and do not hinder the user's activities, the convenience of the private booth 101 can be enhanced.

[0089] Furthermore, in the private booth 101 according to this embodiment, as shown in Figures 11 and 13, the inner surfaces of the surrounding wall 102 and door 103 are formed to open downwards. As described above, the private booth 101 is formed with an opening at the bottom without a floor plate, so vibrations from the raising and lowering of the top plate 161 (vibrations from actuators 162, 162) are not transmitted to the user through the floor plate. In other words, vibrations from the raising and lowering of the top plate 161 that cause discomfort to the user can be suppressed.

[0090] Furthermore, the lower end of the peripheral wall 102, that is, the lower end of the base frame 121, is formed with an open side facing the opening 102a. As a result, wheelchair users do not need to climb or descend any steps when entering or exiting the private booth 101, making it easy to enter and exit. In this way, the private booth 101 in this embodiment eliminates the step between the outside and the inside, making it possible to enter and exit the private booth 101 on the same plane, thereby improving the convenience of the private booth 101 (especially for wheelchair users).

[0091] 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 a wheelchair or user. 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.

[0092] In the private booth 101 according to this embodiment, the peripheral wall 102 on which the top plate 161 is provided intersects with the surface on which the door 103 is provided. A side panel 134 is provided on the left side of the surface on which the door 103 is provided. Furthermore, as shown in Figure 12, the depth dimension of the top plate 161 is formed to be smaller than the width dimension of the side panel 134. This allows users of the private booth 101 to enter and exit without being obstructed by the top plate 161 when the door 103 is opened. In particular, it makes it possible for wheelchair users to easily enter and exit the private booth 101.

[0093] [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.

[0094] The surrounding walls of the private booth can be constructed not only by assembling a base frame with multiple panel bodies as in this embodiment, but also by connecting multiple panel bodies without a base frame. Furthermore, the surrounding walls can be formed into a continuous cylindrical shape (for example, a cylindrical shape) in the circumferential direction.

[0095] 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.

[0096] 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.

[0097] 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 of this embodiment are also possible.

[0098] 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.

[0099] When a door opening and closing mechanism is installed in a private booth, it is also possible to install a closure detection unit similar to the opening detection unit in the private booth. In this case, when the closure detection unit detects a user's closure operation, the opening and closing mechanism will close the door. If the closure operation is performed before a predetermined time has elapsed since the door was opened, the opening and closing mechanism can close the door immediately. It is also possible to configure the door closing operation using only the closure detection unit described above.

[0100] Furthermore, when a door opening and closing mechanism is provided for the private booth, the door can be a sliding door in addition to a hinged door. It is also possible for the private booth to be configured without casters or grounding components. Additionally, it is possible for the private booth to be configured without a height-adjustable top panel. Furthermore, it is possible for the private booth to be configured without side panels.
