[0015] Hereinafter, one embodiment of the present invention will be described with reference to FIGS.

[0016] As shown in Figures 1 to 3, 5, 8, 9, and 11 to 13, booth B of this embodiment is a portable booth in which peripheral wall panels 1 and 2 are supported on a base frame 3 composed of frame members 31, and casters 32 are provided on the base frame 3 to make it movable. The casters 32 are arranged in a recessed position inside the base frame 3, with some exceptions. As shown in Figure 11, the casters 32 are low-profile casters, with wheels 325 pivotally supported on flat supports 323. The rolling direction of the wheels 325 changes as the supports 323 rotate horizontally. As shown in Figures 12 and 13, the base frame 3 has a frame member continuous section 3A where frame members 31 are continuously arranged, and a frame member removed section 3B formed between open ends 31a of the frame members 31. The frame member continuous section 3A supports the panels 1 and 2, and a door panel 5 is arranged in the frame member removed section 3B so that it can be opened and closed.

[0017] More specifically, this booth B is for personal use by one person, and as shown in Figures 3, 5, 8, 9, and 12, it has an interior space S formed by covering at least three sides excluding the front with peripheral wall panels 1 and 2, and a door panel 5 is disposed on the front corresponding to the frame material removed portion 3B of the base frame 3. The upper surface of the room, which is the interior space S, is covered with a ceiling panel 9 equipped with a downward-discharge type automatic fire extinguishing device 94.

[0018] As shown in Figures 5, 8, 9, 14, and 15, the peripheral wall panels 1 located on the sides of the booth B include a sheet metal side panel main body 11 that forms the outer surface of the booth B, and a sheet metal side panel inner plate 12 attached to the room side (the interior space S side) of the side panel main body 11. The side panel main body 11 is rectangular and covers the side surface of the interior space S, and includes horizontal plate portions 111 that extend inward at the upper and lower edges. The front edges of the side panel main body 11 include forward-facing vertical plate portions 112 that extend toward the room side, and inward-facing vertical inner plate portions 113 that extend rearward from the extending ends of the forward-facing vertical plate portions 112. The rear edge of the side panel body 11 is integrally provided with a first rearward-facing vertical plate portion 114 extending toward the room side, an inward-facing vertical inner plate portion 115 extending forward from the extending end of the first rearward-facing vertical plate portion 114, and a second rearward-facing vertical plate portion 116 extending toward the room side from the extending end of the inward-facing vertical plate portion 115. The inward-facing vertical plate portion 115, the second rearward-facing vertical plate portion 116, and the inner surface of the side panel inner plate 12 form a joint surface 1a that is bent at an angle of 90° in a plan view. 13 is a soundproofing plate attached to the side of the interior space S of the peripheral wall panel 1. 14 is a wiring cover attached to the side of the interior space S of the peripheral wall panel 1. 16 is a table top used by users of the booth B. Reference numeral 17 denotes a bracket for attaching the table top 16 to the peripheral wall panels 1 and 2. Reference numeral 18 denotes a wiring duct provided on the underside of the table top 16.

[0019] As shown in Figures 5, 8, 14, and 15, the peripheral wall panel 2 located at the rear of booth B includes a sheet metal back panel main body 21 that forms the outer surface of booth B, and a sheet metal back panel inner panel 22 attached to the interior side of this back panel main body 21. The back panel main body 21 is rectangular and covers the side of the interior space S, and includes horizontal panel portions 211 that extend inward at its upper and lower edges. The left and right edges of the back panel main body 21 are integrally provided with first outward vertical panel portions 212 that extend forward, and forward-facing vertical panel portions 213 that extend inward from the extending ends of the first outward vertical panel portions 212. The left and right edges of the back panel inner panel 22 are each provided with a second outward vertical panel portion 221 that extends rearward and is adjacent to the forward-facing vertical panel portion 213 of the back panel main body 21. The first outward vertical plate portion 212, the forward vertical plate portion 213, and the second outward vertical plate portion 221 form a joint surface 2a that is bent at an angle of 90° in a plan view.

[0020] The base frame 3 is U-shaped in plan view, and as shown in Figures 6 and 12, casters 32 are provided at four locations on the bottom side. That is, as shown in Figures 6, 12, and 13, the base frame 3 has a frame member continuation portion 3A where frame members 31 are continuously arranged, and a frame member removal portion 3B formed between the open ends 31a of the frame members 31. The frame member continuation portion 3A supports the panels 1 and 2, and the frame member removal portion 3B has a door panel 5 arranged in an openable / closable manner. As shown in Figures 3, 6, and 21, the frame member 31 of the base frame 3 is channel-shaped and includes an outer plate 311, an inner plate 312, and an upper plate 313 connecting the upper edges of the outer plate 311 and the inner plate 312. The width w from the outer plate 311 to the inner plate 312 is set larger than the thickness t1 of the panels 1 and 2. Caster seats 321 are fixedly provided at the front and rear ends of the leg regions extending in the front-rear direction of the base frame 3, and casters 32 are provided on these caster seats 321, respectively.

[0021] As shown in Figure 11, the caster 32 includes a support 323 supported on a caster seat 321 via a thrust bearing 322 so as to be horizontally rotatable, and a wheel 325 journaled on the support 323 via a support shaft 324, and the entire caster 32 is housed inside the frame 31 except for a portion of the support, specifically, the ground-contacting half of the wheel 325. In other words, the caster 32 is housed inside the frame 31 with only a portion of the wheel 325 protruding outside. The caster 32 is a low-floor caster type in which the wheel 325 is pivotally supported on a flat support 323 and the rolling direction of the wheel 325 changes as the support 323 rotates horizontally, and the flat support 323 has a maximum vertical dimension h that is set to a value smaller than its maximum horizontal dimension s.

[0022] The caster seat 321 is also equipped with an adjuster 33. As shown in FIG. 11, the adjuster 33 can be moved between a retracted position, in which the entire load is borne by the caster 32, and a protruding position, in which the entire load is not borne by the caster 32. That is, by lowering the adjuster 33 to the protruding position, the caster 32 can be placed in a light contact state, in which no load is applied, or in a state in which the caster 32 is raised above the floor. The adjuster 33 includes a threaded rod 331 threadedly attached to the caster seat 321 and a grounding portion 332 at the lower end of the threaded rod 331. The upper end of the threaded rod 331 is formed with an engagement portion, such as a hexagonal hole, for engaging a height-adjusting tool (not shown). The upper plate 313 of the frame member 31 is formed with a tool insertion hole 313a corresponding to the engagement portion of the adjuster 33, so that the height of the adjuster 33 can be adjusted by rotating the threaded rod 331 from inside the room. Specifically, the upper plate 313 of the frame material 31 in the base frame 3 has the panels 1 and 2 for the peripheral walls placed on its outer half, and the tool insertion hole 313a described above is arranged on its inner half.

[0023] As mentioned above, booth B comprises panels 1 and 2 for the peripheral walls, a door frame 4 arranged adjacent to these panels 1 and 2, and a base frame 3 that supports these panels 1 and 2 and door frame 4 from below.The door frame 4 has a frame material removal portion 4B at a position corresponding to the frame material removal portion 3B of the base frame 3, and cooperates with the base frame 3 to form a frame structure that has a closed loop shape when viewed from above.

[0024] 2, 12, 13 and 22, the door frame 4 is a gate-shaped structure having a pair of support posts 41 erected at the open end 31a of the base frame 3 and a cross member 42 connecting the upper ends of these support posts 41, with a frame material removal portion 4B being disposed between the lower ends of both support posts 41. The upper ends of the peripheral wall panels 1 and 2 and the upper end of the door frame 4 disposed adjacent to these panels 1 and 2 are fastened to the ceiling panel 9 and connected to each other.

[0025] As shown in Fig. 5, the horizontal width w of the base frame 3 is set to a value corresponding to the sum of the thickness t1 of the peripheral wall panels 1 and 2 and the thickness t2 of the support pillar 41. The peripheral wall panels 1 and 2 are placed on the outer half of the base frame 3, and the support pillar 41 of the door frame 4 is erected on the inner half of the base frame 3. The inner side of the front end of the peripheral wall panel 1 located on the side of the booth B is connected to the outer side of the support pillar 41 via a connector 6 that engages when the panel 1 is lowered relative to the support pillar 41, as will be described later and as shown in Figs. 3, 13, and 22. The base frame 3 is provided with a fastener 34 that prevents the panel 1 from moving upward after connection. The fixing device 34 is plate-shaped and has a bolt insertion hole 34a. By passing a bolt (not shown) through the bolt insertion hole 34a and screwing it into the panel 1, the panel 1 is prevented from moving upward relative to the base frame 3, and the connected state by the connecting device 6 is maintained.

[0026] 9, 13, and 22, an upwardly projecting protrusion 314 is fixed by welding or the like to the upper surface of the base frame 3 near the open end 31a. Then, as shown in FIG. 22, the lower end of the door frame 4 (the lower end of the support pillar 41) is fitted onto the protrusion 314, and the two are fastened together with screws in this state, whereby the door frame 4 is fixed onto the base frame 3.

[0027] Here, we will explain the connection between the peripheral wall panel 1 arranged on the base frame 3 and the support pillars 41 of the door frame 4. As described above, this booth B is made up of a plurality of peripheral wall panels 1, 2 and support pillars 41 erected on the base frame 3, and the panels 1, 2 are connected to each other and the panel 1 to the support pillars 41 by a common connector 6. As shown in Figures 13, 14 and 16 to 19, one end of the connector 6 engages with a slit 7s formed in the support pillar 41 or the panel 1, and the other end engages with a slit 8s formed in the other panel 1, 2.

[0028] 14 to 19, the connector 6 connects a first plate-like portion 7 with a slit 7s that engages at one end to a second plate-like portion 8 with a slit 8s that engages at the other end, with the first plate-like portion 7 constituting a part of the support 41 or the panel 1, and the second plate-like portion 8 constituting a part of the other panel 1, 2. More specifically, the connector 6 used on the front side of the booth B, as shown in FIGS. 13 and 14, is for connecting the outer plate portion 411 (first plate-like portion 7) of the support 41 in the door frame 4 to the inward vertical plate portion 113 (second plate-like portion 8) of the panel 1 located on the side of the booth B. In addition, the connector used on the rear side of booth B is intended to connect the rearward-facing vertical plate portion 116 (first plate-shaped portion 7) of the peripheral wall panel 1 located on the side of booth B with the forward-facing vertical plate portion 213 (second plate-shaped portion 8) of the peripheral wall panel 2 located on the back of booth B, as shown in Figures 13 and 15.

[0029] Thus, the peripheral wall panel 1 located on the side of booth B and the peripheral wall panel 2 located on the rear of booth B are connected by tightly engaging their curved joint surfaces 1a, 2a, as shown in Figures 8, 13, and 15. A part of the joint surface 1a of one panel 1 (rear-facing vertical plate portion 116) forms the first plate-like portion 7, and a part of the joint surface of the other panel 2 that is in close contact with this first plate-like portion 7 (forward-facing vertical plate portion 213) forms the second plate-like portion 8.

[0030] As shown in Figures 14 to 19, the connecting device 6 comprises a bridging member 61 that passes through both slits 7s, 8s of the first and second plate-shaped portions 7, 8 to be connected, a first claw member 62 that is provided at one end of the bridging member 61 and engages with the inner surface of the first plate-shaped portion 7, and a second claw member 63 that is provided at the other end of the bridging member 61 and engages with the inner surface of the second plate-shaped portion 8, and is made integrally from, for example, a metal plate.

[0031] As shown in Figures 14 to 19, the first claw member 62 and the second claw portion 63 of the connecting device 6 respectively include upward claw portions 621, 631 that extend above the bridging member 61, and downward claw portions 622, 632 that extend below the bridging member 61. The upward claw portion 621 and the downward claw portion 622 of the first claw member 62 and the upward claw portion 631 and the downward claw portion 632 of the second claw member 63 have mutually different shapes, and as will be described later, can be engaged with slits 7s, 8s of different shapes.

[0032] As shown in Fig. 18, the slit 7s of the first plate-shaped portion 7 has an opening dimension d1 that is shorter than the vertical dimension h2 of the first claw member 62 of the connector 6, and is sized so that the first claw member 62 can be engaged with the slit 7s by a pushing action, as shown in Fig. 17. Also, as shown in Fig. 18, the slit 8s of the second plate-shaped portion 8 has an opening dimension d2 that is longer than the vertical dimension h3 of the second claw member 63 of the connector 6, and is configured so that the first plate-shaped portion 7 and the second plate-shaped portion 8 can be connected together as shown in Fig. 19 by moving the first plate-shaped portion 7 and the second plate-shaped portion 8 relative to each other with the second claw portion 63 inserted into the slit 8s of the second plate-shaped portion 8.

[0033] More specifically, at the front of booth B, as shown in Fig. 14, a first plate-like portion 7 is arranged on the outer surface of a support pillar 41, and a second plate-like portion 8 is arranged on the inner surface of a peripheral wall panel 1 located on the side of booth B, with the front end of this panel 1 attached to the support pillar 41 via a connector 6. At the rear of booth B, as shown in Fig. 15, the peripheral wall panel 1 located on the side of the booth and the peripheral wall panel 2 located on the rear of the booth are connected by tightly engaging their curved joint surfaces 1a, 2a, and the first and second plate-like portions 7, 8 constituting both joint surfaces 1a, 2a are connected to each other via the connector 6.

[0034] Here, a procedure for assembling the door frame 4 and the peripheral wall panel 1 will be specifically described. First, from the state shown in FIG. 16 , the first claw members 62 of the connectors 6 are attached to the slits 7s provided in the outer plate portions 411 (first plate-like portions 7) of the support posts 41 of the door frame 4 by a pawl action, via the state shown in FIG. 17 . In this embodiment, four connectors 6 are attached to each of the left and right support posts 41 at regular intervals in the vertical direction. Thereafter, as shown in FIG. 18 , the panel 1, with the slits 8s of the inward vertical plate portions 113 (second plate-like portions 8) corresponding to the connectors 6, is pressed against the support posts 41, whereby the second claw members 63 of the connectors 6 can be inserted into the slits 8s of the panel 1. In this state, the panel 1 is lowered relative to the support posts 41, whereby the panel 1 and the support posts 41 are connected via the connectors 6, as shown in FIG. 19 . In this state, by screwing the rear end of the lower edge of the panel 1 to the fixture 34 of the base frame 3, the panel 1 is prevented from moving upward, and the connected state is maintained. From this state, the first claw members 62 of the connectors 6 are attached by a pushing motion to the slits 7s formed in the rear-facing vertical plate portion 116 (first plate-like portion 7) located at the rear end of the peripheral wall panel 1 located on the side of the booth B, as shown in Figure 17. In this embodiment, four connectors 6 are attached to each of the left and right panels 1 at regular intervals in the vertical direction. 18, the panel 2 for the peripheral wall located at the back of booth B, with the slits 8s of the forward-facing vertical plate portions 213 (second plate-like portions 8) aligned with each connector 6, is pressed against the rear end of the panel 1 located at the side of booth B, whereby the second claw portions 63 of each connector 6 can be inserted into the slits 8s of the panel 2. In this state, the panel 2 located at the back of booth B is lowered relative to the panel 1 located at the side of booth B, whereby the panels 1 and 2 are connected to each other via the connector 6, as shown in FIG. 19. In this state, the door frame 4 and the panels 1 and 2 are fastened to the ceiling main body 91 of the ceiling panel 9 with screws or the like, whereby the relative vertical movement between the panel 2 for the peripheral wall located at the back of booth B and the panel 1 for the peripheral wall located at the side of booth B is prohibited, and therefore the connected state of the panels 1 and 2 by the connector 6 is maintained. Note that the number of connectors 6 is not limited to that described above and may be set arbitrarily.

[0035] The door panel 5 arranged inside the door frame 4 has its hanging point on the right side when viewed from the front, and is supported on the door frame 4 via a hinge 53 so that it can be opened and closed, as shown in Figures 1, 2, 5, 6, 12 and 13.

[0036] Thus, this booth B is portable as described above, and the base frame 3 has a frame member continuation section 3A where frame members 31 are continuously arranged, and a frame member removal section 3B formed between the open ends 31a of the frame members 31. The frame member continuation section 3A supports the panels 1 and 2, and a door panel 5 is arranged in the frame member removal section 3B so that it can be opened and closed. As shown in Figures 7 and 12, the door panel 5 has a floor-contact member 54 at its lower end that protrudes and retracts toward the floor surface in response to opening and closing operations.

[0037] Specifically, booth B has an interior space S formed by covering at least three sides (excluding the front) with peripheral panels 1 and 2. Base frame 3 includes a continuous frame portion 3A (where frame members 31 are continuously arranged) and a partially removed frame portion 3B (where frame members 31 are partially removed). Door panel 5 is located on the front where the partially removed frame portion 3B is formed. As shown in FIGS. 7 and 9 , door panel 5 includes a button 56 on its front edge 5a (on the hinge side) that abuts against door frame 4 and is depressed inward when the door is closed. A member drive mechanism is provided that, when button 56 is depressed, moves floor-contact member 54 from a standby position (H) spaced apart from floor F to a floor-contact position (L) in contact with floor F. The member drive mechanism converts the retraction and projection of button 56 into the raising and lowering of floor-contact member 54, and can be implemented using an appropriate mechanism, such as a link or cam. The member drive mechanism is not shown in FIG. 7 .

[0038] As shown in Figures 1, 2, 5 to 7, and 12, the door panel 5 is primarily composed of a door body 50 made of, for example, sheet metal, corresponding to the interior shape of the door frame 4. A window 51 fitted with a transparent plate 51a is formed in the center of the door body 50. A channel-shaped component holding frame 55 open downward is embedded in the lower edge of the door body 50, and the aforementioned floor contact component 54 is housed within this component holding frame 55 so that it can protrude and retract relative to the floor surface F. A component driving mechanism is also housed within this component holding frame 55, but this is not shown. The floor contact component 54 is made of an elastic material such as rubber and is held, for example, by the lower edge of an extrusion 57 housed within the component holding frame 55 so that it can rise and fall. 52 denotes a handle. 55a denotes a guide groove formed in the upper part of the component holding frame 55 to guide the button 56 in the forward and backward directions and to prevent it from rotating.

[0039] The ceiling panel 9 is mainly composed of a ceiling main body 91 made of, for example, sheet metal. As shown in Figures 3, 4, 12, and 20, the ceiling main body 91 has a rectangular shape in a plan view and closes the top surface of the interior space S. As shown in Figure 20, a ceiling front frame 911 is provided at the front edge, side flanges 912 are provided at the left and right side edges, and a rear flange 913 is provided at the rear edge, all of which are integrally erected.

[0042] <Effects of the embodiment> With this configuration, the casters 32 are arranged in a position recessed inside the base frame 3, with some exceptions, so that even though the chair can be moved using the casters 32, the gaps SP (SP1, SP2, SP3) formed between the lower end of the base frame 3 and the floor F as shown in Fig. 21 can be made as small as possible. This makes it possible to effectively prevent sound from the internal space S from leaking to the outside through the gaps SP.

[0043] In particular, in this embodiment, the casters 32 are of a low-floor caster type, in which wheels 325 are pivotally supported on flat supports 323, and the rolling direction of the wheels 325 changes with the horizontal rotation of the supports 323. Therefore, even if most of the casters 32 are disposed inside the base frame 3, the vertical dimension of the base frame 3 does not become excessively large.

[0044] Furthermore, in this embodiment, the base frame 3 has a frame material continuation portion 3A and a frame material removal portion 3B, and the panels 1 and 2 are supported on the frame material continuation portion 3A, and the door panel 5 is arranged in the frame material removal portion 3B so that it can be opened and closed.This eliminates the step between the internal space S and the external space O, and allows smooth entry and exit to the internal space S with the door body 50 of the door panel 5 open even while sitting in the wheelchair.

[0045] In this embodiment, the frame member 31 of the base frame 3 is channel-shaped and includes an outer panel 311, an inner panel 312, and an upper panel 313 connecting the upper edges of the outer panel 311 and the inner panel 312. Therefore, as shown in FIG. 21 , the gap SP1 between the lower edge 311 of the outer panel and the floor F, the gap SP2 between the upper panel 313 and the floor F, and the gap SP3 between the lower edge of the inner panel 312 and the floor F change sequentially from small to large to small. As a result, the interior space S and the exterior space O are partitioned by multiple types of gaps SP1, SP2, and SP3 that can provide a labyrinth-like effect, thereby effectively suppressing sound leakage. In this case, the width w from the outer panel 311 to the inner panel 312 is set larger than the thickness t1 of the panels 1 and 2, thereby expanding the area in which the labyrinth-like effect can be provided, resulting in particularly favorable sound leakage prevention.

[0046] In addition, the width dimension w from the outer plate 311 to the inner plate 312 of the frame material 31 is set to be larger than the thickness dimension t1 of the peripheral wall panels 1 and 2. Therefore, for example, the peripheral wall panels 1 and 2 can be supported on the outer half of the frame material 31, and then a tool insertion hole 313a corresponding to the engagement portion of the adjuster 33 can be provided in the inner half of the upper plate 313 of the frame material 31, and a tool can be inserted into this tool insertion hole 313a, allowing the adjuster 33 to be adjusted from the internal space S side.

[0047] Furthermore, according to the configuration of this embodiment, even if the base frame 3 itself is a non-annular body having a frame material removed portion 3B in part, the door frame 4 bridges this frame material removed portion 3B. Therefore, when observing the frame structure as a whole, the base frame 3 and the door frame 4 form a structure that is annular in plan view. Therefore, cooperation between the base frame 3 and the door frame 4 makes it possible to naturally improve the overall rigidity.

[0048] In addition, the door frame 4 is gate-shaped and has a pair of pillars 41 erected at the open end 31a of the base frame 3 and a cross member 42 connecting the upper ends of these pillars 41, and a frame material removal portion 3B of the base frame 3 is arranged between the lower ends of both pillars 41, so that when passing through the door frame 4 to enter or exit the internal space S, one passes through the frame material removal portion 3B, allowing smooth entry and exit to the internal space S while remaining in the wheelchair.

[0049] Furthermore, the upper ends of the peripheral wall panels 1 and 2 and the upper end of the door frame 4 arranged adjacent to these panels 1 and 2 are fastened to a common ceiling panel 9, so that this ceiling panel 9 can be used to connect the panels 1 and 2 and the door frame 4, thereby reducing the number of parts.

[0050] In addition, the horizontal width dimension w of the base frame 3 is set to a value corresponding to the sum of the thickness dimension t1 of the peripheral wall panels 1 and 2 and the thickness dimension t2 of the support pillar 41, and the peripheral wall panels 1 and 2 are placed on the outer half of the base frame 3, while the support pillar 41 of the door frame 4 is erected on the inner half of the base frame 3, so that both the peripheral wall panel 1 and the support pillar 41 can be contained within the horizontal width dimension w of the base frame 3, resulting in a neat appearance.

[0051] Furthermore, the inner side of the front end of the panel 1 for the surrounding wall, more specifically the inward vertical inner plate portion 113, and the outer side of the support 41, more specifically the outer plate portion 411, are connected via a connector 6 that engages when the panel 1 is lowered relative to the support 41, and the base frame 3 is provided with a fixing device 34 that prevents the panel 1 from moving upward after connection, so that the panel 1 can be easily attached to the support 41 while the fixing device 34 prevents the panel 1 from moving upward, thereby preventing the panel 1 from coming off.

[0052] Furthermore, a protrusion 314 that protrudes upward is fixed to the base frame 3, and the lower end of the door frame 4 is fitted into and secured to this protrusion 314, making it easy to position the door frame 4 relative to the base frame 3.

[0053] The present invention is not limited to the above-described embodiment.

[0054] For example, the shape of the base frame is not limited to the one with the frame material removed from the front as in the above-mentioned embodiment, but may be one with the frame material removed from the side. Specifically, as shown in Figure 23, a door frame may be provided in part of the area that would become the side wall.

[0055] The base frame A3 of this embodiment includes a continuous frame portion A3A in which frame members A31f, A31s, A31b, and A31t are arranged in succession, and a frame-removed portion A3B formed between the open ends A31a of the frame members A31f and A31t. The continuous frame portion A3A includes a front frame member A31f supporting a peripheral wall panel (not shown) located at the front of the booth, a first frame member A31s supporting a peripheral wall panel (not shown) located across the entire area of ​​one side of the booth, a rear frame member A31b supporting a peripheral wall panel (not shown) located at the rear of the booth, and a second frame member A31t supporting a peripheral wall panel (not shown) located in the rear half of the other side of the booth. The open ends A31a are the end of the front frame member A31f on the other side and the front end of the second frame member A31t. A door panel (not shown) is arranged in the removed frame portion A3B so that it can be opened and closed. Each of the frame members A31f, A31s, A31b, and A31t of the base frame A3 has the same configuration as the frame member 31 of the booth B shown in the embodiment described above with reference to Figures 1 to 21, so detailed description will be omitted.

[0056] An upwardly projecting protrusion A314 is fixed by welding or the like to the upper surface of the base frame A3 near the open end A31a. The lower end of the door frame A4 (the lower end of the support pillar A41) is fitted onto the protrusion A314, and the two are fastened together with screws, thereby fixing the door frame A4 to the base frame A3. Note that A34 is a fixing device that prevents the peripheral panel from moving upward after connection.

[0057] The door frame A4 is a gate-shaped door frame having a pair of pillars A41 erected at the open end A31a of the base frame A3 and a cross member A42 connecting the upper ends of these pillars A41, and a frame material removal portion A4B is arranged between the lower ends of the two pillars A41.

[0058] Even in this configuration, the most important effect of the present invention can be obtained: even if the base frame A3 itself is a non-annular body having a frame material removed portion A3B in part, the door frame A4 bridges this frame material removed portion A3B, and the base frame A3 and the door frame A4 form a structure that is annular in plan view, and this cooperation between them makes it possible to reasonably improve the overall rigidity.

[0059] In addition, the door frame A4 is gate-shaped and has a pair of pillars A41 erected at the open end A31a of the base frame A3 and a cross member A42 connecting the upper ends of these pillars A41, and a frame material removal portion A3B of the base frame A3 is arranged between the lower ends of the two pillars A41, so that when passing through the door frame A4 to enter or exit the internal space, one passes through the frame material removal portion A3B, allowing smooth entry and exit to the internal space while remaining in the wheelchair.

[0060] The shape of the base frame is not limited to one in which a frame material removal portion is provided across almost the entire width of the front face as in the embodiment described above with reference to Figures 1 to 22, or one in which a frame material removal portion is provided on a portion of the side face as in the embodiment described above with reference to Figure 23, but various other shapes may be adopted, such as one in which a frame material removal portion is provided on only a portion of the front face, one in which a frame material removal portion is provided across the entire side face, or one in which a frame material removal portion is provided across both the front face and the side face.

[0061] Furthermore, for example, if the casters are arranged in a position where all but a portion are recessed inside the base frame, it is not necessary to arrange low-profile casters within the frame material of a base frame constructed using a channel-shaped frame material as in the above-mentioned embodiment. However, if the low-profile casters are configured such that the wheels are pivotally supported on a flat support body and the rolling direction of the wheels changes as the support body rotates horizontally, as described above, even if most of the casters are arranged within the base frame, the vertical dimension of the base frame can be prevented from becoming excessively large. Furthermore, if the casters are arranged within the frame material of a base frame constructed using a channel-shaped frame material, the frame material formed by extrusion processing or the like can be used as is without specially providing recesses in the frame material to accommodate the casters, thereby preventing an increase in processing man-hours.

[0062] The number of panels is not limited to 3 or 4. In other words, the panels for the peripheral walls located on the sides or back of the booth may be divided into multiple pieces, and as shown in Figure 22, if the frame material is removed only in part of the front or side, panels may also be supported on other parts of the front or side, i.e., parts where the frame material is continuous.

[0063] In the illustrated example, the table top is set to a height that can be used conveniently in a seated position, but it may also be set to a height that can be used conveniently in a standing position.

[0064] In the embodiment described above with reference to Figures 1 to 22, the upper ends of the peripheral wall panels and the upper ends of the door frames arranged adjacent to these panels are fastened to a common ceiling panel, but any mounting method for the ceiling panel may be adopted, and the ceiling panel may be omitted.

[0065] Furthermore, the horizontal width of the base frame, the thickness of the peripheral wall panel, the thickness of the door frame support pillars, and their arrangement may be set arbitrarily.

[0066] Any method of attaching the peripheral wall panels to the support posts and the door frame to the base frame may be adopted, and the base frame and the door frame may be integrally formed by welding or the like.

[0067] In addition, various modifications may be made without departing from the spirit of the present invention. [Explanation of symbols]
