[0011] [Booth equipment 1] A booth apparatus 1 according to a first embodiment of the present invention will be described below with reference to Figs. 1 to 9. The booth apparatus 1 according to this embodiment is an example of a private booth according to the present invention. As shown in Figs. 1 and 2, the booth apparatus 1 according to this embodiment is placed on the floor and used for indoor use by one person or a small number of people. The booth apparatus 1 is mainly constructed by combining metal members such as steel or aluminum alloy. In this embodiment, the directions of the booth apparatus 1 are defined by arrows in Fig. 1.

[0012] 1 and 2, the booth apparatus 1 according to this embodiment is provided with a cylindrical peripheral wall 2 having an opening 2a formed at the top, thereby forming a private room. The peripheral wall 2 is formed into a rectangular shape in a plan view, as shown in FIGS. 1, 2, and 4. The peripheral wall 2 is made up of support columns 21 arranged at the four corners in the vertical direction, side panels 22 arranged on both sides of the peripheral wall 2, a door frame panel 23 and a door 24 arranged at the front of the peripheral wall 2, and a back panel 25 arranged at the rear of the peripheral wall.

[0013] 1 and 4, the support pillars 21 are columnar members arranged at the four corners of the peripheral wall 2, to which the side panels 22, door frame panels 23, doors 24, and back panel 25 are attached. Side cover members 21a are attached to the side surfaces of the support pillars 21 exposed to the outside of the peripheral wall 2. Furthermore, an upper cover member 21b is attached to the upper surfaces of the support pillars 21.

[0014] 8 and 9(a), the support pillar 21 is formed with longitudinally extending protrusions 21c that protrude diagonally in the front, rear, left, and right directions and serve as corners of the support pillar 21. Numerous engagement holes 21d are formed on the outer surface of the protrusions 21c. The spaces between the protrusions 21c are formed as insertion sections 21e into which connecting members such as the side plates 22 can be inserted or into which the wiring cord C or the like can be inserted (see FIGS. 9(a) and 9(b)).

[0015] The side panels 22 and the back panel 25 are attached to the support posts 21 via connecting members 22b and 25b fixed to the upper parts of the side panels 22 and the back panel 25. Specifically, as shown in FIG. 9(a), locking portions are formed at the ends of the connecting members 22b and 25b, and these locking portions extend from the end faces of the side panels 22 and the back panel 25. The locking portions are inserted between the protrusions 21c and 21c of the support posts 21, thereby connecting the connecting members 22b and 25b to the support posts 21. The lower parts of the side panels 22 and the back panel 25 are also connected to the support posts 21 in the same way as the upper parts. The door frame panel 23 is also attached to the support posts 21 in the same way as the side panels 22 and the back panel 25.

[0016] 1, the door frame panel 23 and the door 24 are rotatably assembled via hinges H. A door knob 24a is provided on the door 24. A door closer 24b is also provided on the upper rear surface of the door 24. In this embodiment, a transparent glass panel is assembled to the door 24, but the door 24 may also be made of an opaque material.

[0017] In this embodiment, two side plates 22 are connected to each other and disposed on both sides of the peripheral wall 2. A groove 22a is formed on the upper edge of each side plate 22, allowing the side plates 22 to communicate with each other. As shown in Figures 11 and 12, locking portions 22c are formed on the inner surface of the groove 22a in the longitudinal direction, protruding and facing each other. A groove 25a is also formed on the upper edge of the back plate 25.

[0018] The outer dimensions of the peripheral wall 2 can be changed by changing the width dimensions (horizontal length dimension perpendicular to the thickness direction) of the side panels 22, the door frame panels 23 and the doors 24, and the back panel 25. In other words, the booth apparatus 1 can be appropriately changed in size in the front-to-back and left-to-right directions by changing the outer dimensions of the peripheral walls 2.

[0019] 2 to 4, a plurality of sound-absorbing panels 42 made of a sound-absorbing material such as nonwoven fabric are provided on the inner surface of the peripheral wall 2, at the rear of the side panels 22 and on the back panel 25 (opposite the door 24). According to the booth apparatus 1 of this embodiment, the sound-absorbing panels 42 absorb the voices of the user inside the booth apparatus 1, thereby improving the sound insulation of the booth apparatus 1 (attenuation of the sound volume transmitted between the inside and outside of the booth apparatus 1). In this embodiment, the plurality of sound-absorbing panels 42 are provided separately in the vertical direction and are each independently attachable to and detachable from the peripheral wall 2.

[0020] In the booth apparatus 1 according to this embodiment, a roof member 31, a first louver member 32, and a second louver member 33 are provided as shielding parts at the opening 2a of the peripheral wall 2, as shown in Figures 1 to 4. In this embodiment, the roof member 31, the first louver member 32, and the second louver member 33, which are shielding parts, are configured so that a sound-absorbing material such as a nonwoven fabric is exposed.

[0021] In this embodiment, the roof member 31, first louver member 32, and second louver member 33, which are the shielding portions, are configured to shield an area of ​​30% or less of the opening area of ​​the opening 2a in a plan view, thereby ensuring that water is sprayed from above by sprinklers or the like in the event of a fire.

[0022] 1 and 2, the roof member 31 is a plate-like member arranged substantially horizontally so that its horizontal dimensions (front-to-back and left-to-right dimensions) are greater than its height. Also, as shown in FIG. 7(b), the roof member 31 includes a roof main body portion 31a recessed in the vertical direction so as to have a rectangular shape in a plan view, and hook-shaped engaging portions 31b formed on both the left and right sides of the roof main body portion 31a. In the booth apparatus 1, the engaging portions 31b of the roof member 31 engage with the grooves 22a of the opposing side plates 22, thereby assembling the roof member 31 to the peripheral wall 2.

[0023] 1 to 4, the roof member 31 of the booth apparatus 1 is open between two opposing side edges in the front-to-rear direction and the peripheral wall 2. In other words, a gap is formed between the roof member 31 and the peripheral wall 2 (the door frame panel 23, the door 24, and the back panel 25) on both the front and rear sides.

[0024] Four first louver members 32 are provided in the gap between the roof member 31 and the door frame panel 23 and door 24. Four second louver members 33 are provided in the gap between the roof member 31 and the back panel 25. The number of each louver member is not limited, and other numbers are also possible.

[0025] 1 and 2, the first louver member 32 and the second louver member 33 are plate-shaped members arranged so that their up-down and left-right dimensions are greater than their front-to-rear dimensions. Also, as shown in Fig. 7(b), the first louver member 32 includes a plate-shaped first louver portion 32a arranged parallel to the door 24 and hook-shaped first engagement portions 32b formed on both the left and right sides of the first louver portion 32a. Also, as shown in Fig. 7(c), the second louver member 33 includes a plate-shaped second louver portion 33a arranged parallel to the back panel 25 and hook-shaped second engagement portions 33b formed on both the left and right sides of the second louver portion 33a.

[0026] 7(a) and 7(c), in the booth apparatus 1, the first engaging portions 32b and the second engaging portions 33b are engaged with the grooves 22a of the opposing side plates 22, thereby assembling the first louver members 32 and the second louver members 33 to the peripheral wall 2. In this embodiment, as shown in FIG. 7(c), a sound-absorbing panel 42 is provided on the side plate 22 in the portion where the second louver members 33 are to be assembled, and therefore the second louver portions 33a are formed so that their width in the left-right direction is smaller than that of the first louver portions 32a.

[0027] In the booth apparatus 1 according to this embodiment, the engaging portions 31b of the roof member 31, the first engaging portions 32b of the first louver members 32, and the second engaging portions 33b of the second louver members 33 can be positioned at any position in the front-rear direction in the grooves 22a of the side panels 22. It is also possible to form a plurality of slits at predetermined intervals in the grooves 22a and insert the engaging portions 31b, the first engaging portions 32b, and the second engaging portions 33b into the slits, thereby restricting the front-rear positions of the roof member 31, the first louver members 32, and the second louver members 33. Alternatively, a positioning metal fitting having slits formed therein can be fixed to the grooves 22a along the longitudinal direction of the grooves 22a, and the engaging portions 31b, the first engaging portions 32b, and the second engaging portions 33b can be inserted into the slits of the positioning metal fitting, thereby assembling the roof member 31, the first louver members 32, and the second louver members 33 in a state where they are positioned in the grooves 22a.

[0028] As described above, in the booth apparatus 1 according to this embodiment, the roof member 31 reflects the voice of a user inside the booth apparatus 1, making it difficult for the voice to be emitted to the outside of the booth apparatus 1, thereby improving the sound insulation of the booth apparatus 1. Furthermore, since the roof member 31 has an open space between the two opposing side edges in the front-rear direction and the peripheral wall 2, it does not impede the spraying of water from above by a sprinkler or the like.

[0029] Furthermore, in the booth apparatus 1 according to this embodiment, the voice of the user inside the booth apparatus 1 is reflected between the first louver members 32 and between the second louver members 33, making it difficult for the voice to be emitted outside the booth apparatus 1, thereby further improving the soundproofing of the booth apparatus 1.

[0030] In the booth apparatus 1 according to this embodiment, speakers S are provided on inner peripheral surfaces (inner surfaces of the side plates 22) that face each other in the left-right direction in the peripheral wall 2. As shown in Figures 3 and 4, the speakers S are attached to the side plates 22 via mounting frames 41. The mounting frames 41 are ladder-shaped optional mounting frames made up of a frame body, and are connecting members that are inserted between the side plates 22 and the sound-absorbing panels 42.

[0031] 5, the mounting frame 41 includes a locking portion 41a formed at the upper end, a frame 41b that forms the framework of the mounting frame 41, and a support plate 41c that is provided on the frame 41b and to which the speaker S is fixed. When assembling the mounting frame 41 to the side plate 22, first, the locking portion 41a is locked into the groove portion 22a of the side plate 22, as shown in FIG.

[0032] Thereafter, as shown in Fig. 6, the speaker S is attached to the support plate 41c. The mounting frame 41 is covered by attaching the sound-absorbing panel 42 to the side plate 22. Furthermore, as shown in Fig. 3, the sound-absorbing panel 42 with the window portion 42a opened is attached around the speaker S, thereby completing the booth apparatus 1 with the speaker S exposed to a part of the sound-absorbing panel 42. In this embodiment, the surface of the speaker S is covered with a cover member made of mesh fabric or the like.

[0033] 4, in the booth apparatus 1 according to this embodiment, the speaker S and the roof member 31 are provided in an overlapping area in a plan view. As a result, by reflecting the sound from the speaker S by the roof member 31, the sound from the speaker S is less likely to be emitted to the outside of the booth apparatus 1, and the sound insulation of the booth apparatus 1 can be further improved. Note that, from the viewpoint of making it less likely that the sound from the speaker S is emitted to the outside, it is preferable to employ a directional speaker as the speaker S. Furthermore, by arranging the speakers S so that the user is sandwiched between them on the left and right, it is possible to suppress the volume of the speakers S, and therefore it is possible to make it less likely that the sound from the speaker S will leak to the outside of the booth apparatus 1.

[0034] In the booth apparatus 1 according to this embodiment, the sound-absorbing panel 42 is attached to the mounting frame 41 via resin rivets or the like. It is also possible to attach the sound-absorbing panel 42 to the side panels 22 and the back panel 25 by attracting a magnetic material fixed to the sound-absorbing panel 42, or to fix the sound-absorbing panel 42 to the side panels 22 and the back panel 25 by adhesive.

[0035] Inside the booth apparatus 1 according to this embodiment, a top plate 52 is provided along the back plate 25. Specifically, as shown in Fig. 8, engaging portions 51a formed on the top plate bracket 51 are engaged with engaging holes 21d of the support columns 21, thereby assembling the top plate bracket 51 to each of the two support columns 21 located at the rear of the booth apparatus 1. Then, the top plate 52 is fixed to the upper portions of the two top plate brackets 51, thereby providing the top plate 52 inside the rear of the booth apparatus 1 (at a position along the back plate 25).

[0036] 3 and 8, in the booth apparatus 1 according to this embodiment, a tray 53 for accommodating communication devices, wiring, etc. is provided between two top plate brackets 51. A cover 54 for covering the upper side of the tray 53 is fixed to the front side of the tray 53.

[0037] 2 to 4, in the booth apparatus 1 according to this embodiment, the rear end of the top plate 52 is disposed near the roof member 31 in a plan view. Since the user of the booth apparatus 1 often speaks while sitting near the front side of the top plate 52, by bringing the rear end of the top plate 52 and the roof member 31 closer together in a plan view as described above, the head of the user of the booth apparatus 1 can be positioned below the roof member 31. This makes it easier for the roof member 31 to reflect the voice of the user of the booth apparatus 1. In other words, according to the booth apparatus 1 according to this embodiment, the voice of the user is less likely to be emitted to the outside of the booth apparatus 1, and therefore the sound insulation of the booth apparatus 1 can be further improved (see test results described later).

[0038] In particular, in the booth apparatus 1 according to this embodiment, the roof member 31 is fixed to the two side plates 22. This allows voices inside the booth apparatus 1 to be reflected by the roof member 31 near the side plates 22, making it difficult for the voices to be transmitted to the outside of the booth apparatus 1 to the sides.

[0039] Furthermore, as in this embodiment, by positioning the head of the user of the booth apparatus 1 below the roof member 31, it is possible to prevent sounds outside the booth apparatus 1 from reaching the user. That is, in the booth apparatus 1 according to this embodiment, the roof member 31 blocks external sounds coming from above the user, thereby making it possible to further improve sound insulation.

[0040] [Booth Unit 100] Next, the booth unit 100 will be described with reference to Figure 10. The booth unit 100 according to this embodiment is formed by connecting two booth apparatuses 1 according to the above embodiment in the left-right direction. The components that make up the booth unit 100 are the same as those of the booth apparatus 1, and therefore detailed description thereof will be omitted.

[0041] In the booth unit 100 according to this embodiment, the left and right booth apparatuses 1 share the two support columns 21 and the side plate 22 disposed between them. Therefore, in the booth unit 100 according to this embodiment, the mounting frames 41, 41 assembled opposite to each other on the same side plate 22 are configured to be located at the same position in the front-to-rear direction without interfering with each other.

[0042] 11 and 12(a), the mounting frame 41 in this embodiment is formed by bending the claw-shaped locking portions 41a perpendicularly to a fixing plate 41d formed at the upper end of a frame 41b. In this case, as shown in Fig. 12(b), the distance from the center line L of the fixing plate 41d to the left locking portion 41a is formed to be greater than the distance to the right locking portion 41a.

[0043] 12(a) and 12(b), when the mounting frames 41 are engaged with the grooves 22a of the side plates 22 and the locking portions 41a are locked with the locked portions 22c, the center lines of the fixing plates 41d can be aligned with each other. In other words, the mounting frames 41, 41 that are assembled facing each other can be provided at the same position in the front-to-rear direction on the side plates 22 without interfering with each other.

[0044] In the booth unit 100 according to this embodiment, the roof member 31 provided on each booth apparatus 1 is fixed to one peripheral wall 2 (in this embodiment, a side panel 22 provided between the two booth apparatuses 1·1) arranged between the adjacent booth apparatuses 1, and to the other peripheral wall 2 opposite the one peripheral wall 2 (in this embodiment, side panels 22·22 provided on the left-right outer sides of the booth unit 100).

[0045] With the booth unit 100 configured as described above, voices uttered by neighboring booth apparatuses 1 and 1 can be reflected by the roof member 31 near the side panels 22. This makes it difficult for voices to leak outside to the sides of the booth apparatus 1, making it difficult for voices to be transmitted between the booth apparatuses 1 and 1. In other words, it is possible to further improve sound insulation between the booth apparatuses 1 and 1.

[0046] Furthermore, inside each booth apparatus 1·1 in the booth unit 100 according to this embodiment, a top panel 52 is provided along a back panel 25 that intersects with the side panels 22 (see FIG. 2). This allows a user using the top panel 52 inside each booth apparatus 1·1 to be positioned facing the back panel 25. This allows the user to speak in a direction perpendicular to the adjacent booth apparatus 1·1 (rearward in this embodiment), thereby further improving sound insulation between the adjacent booth apparatuses 1·1.

[0047] Furthermore, when using the booth unit 100 of this embodiment, from the viewpoint of minimizing the impact of sound leakage to the outside, it is preferable to place the back panel 25 of the booth apparatus 1 constituting the booth unit 100 close to the wall.

[0048] [Measurement test results] Next, the results of a measurement test conducted by the applicant to verify the sound insulation of the booth unit 100 will be explained with reference to Fig. 13. As shown in Fig. 13(a), the applicant used two consecutive booth devices (a speech booth Bs and a measurement booth Bm) similar to the booth unit 100 to test their sound insulation against each other.

[0049] In this test, the speech booth Bs and the measurement booth Bm were configured to have the same configuration as the peripheral wall 2 in the booth apparatus 1, so that both booths were under the same conditions. In addition, sound-absorbing panels P similar to the sound-absorbing panels 42 provided in the booth apparatus 1 were placed on both sides of the room, on both the left and right sides and at the front. Then, as indicated by the arrow St, a speaker placed at a speech point Ps in the center of the speech booth Bs was used to emit a sound at 500 Hz toward the front. Furthermore, the volume was measured at a measurement point Pm in the center of the measurement booth Bm adjacent to the speech booth Bs.

[0050] In this test, as shown in Figure 13(b), Tests 1 to 5 were conducted, which differed in the placement of the roofing and louver elements. Specifically, Test 1 was configured without roofing or louver elements. Test 2 was configured with the roofing elements blocking the entire upper opening, with no louver elements. Test 3 was configured with the roofing elements blocking the front 30% of the upper opening, with no louver elements. Test 4 was configured with the roofing elements blocking 30% of the upper opening (above the sounding point Ps and measurement point Pm), with no louver elements. Test 5 was configured with the roofing elements positioned above the upper opening (above the sounding point Ps and measurement point Pm), and with a total of 10 louver elements positioned in front and behind the roofing elements, so that the roofing and louver elements blocked a total of 30% of the opening.

[0051] In this test, as shown in Figure 13(b), for each of Tests 1 to 5, the effect of reducing the measured sound volume was measured in comparison with the condition where the sound volume was measured near the phonation point Ps (hereinafter referred to as the "basic condition"). That is, in Test 1, where no roof member was provided, a sound volume reduction effect of 19.1 dB was confirmed compared to the basic condition. Also, in Test 2, where all openings were closed with roof members, a high sound volume reduction effect of 28.7 dB was confirmed compared to the basic condition.

[0052] On the other hand, as shown in Figure 13(b), Test 3, in which the front 30% of the booth was blocked off with a roof member, only achieved a sound volume reduction of 20.2 dB compared to the base conditions, and no significant difference was observed from Test 1, in which no roof member was installed. Test 4, in which the overhead 30% was blocked off with a roof member, demonstrated a sound volume reduction of 25.2 dB compared to the base conditions. Thus, this test demonstrated that placing the roof member above the speaking point (above the booth user's head) reduced sound volume by more than 5 dB compared to placing the roof member in the front, demonstrating high sound insulation without impeding water spraying.

[0053] Furthermore, Test 5, in which 30% of the overhead space was blocked off with roof and louver elements, demonstrated a sound reduction of 27.9 dB compared to the basic conditions, similar to Test 2, in which all openings were blocked off with roof elements. This test thus confirmed that sound insulation can be further improved by installing louver elements in addition to roof elements.

[0054] [Other variations] The above embodiment can be modified as appropriate as shown in the other modifications below. Note that each modification described in this specification may be applied in combination with other modifications to the extent that no contradiction occurs.

[0055] The booth device may have a shape other than a rectangle in plan view, such as a circle, a triangle, a pentagon, or a trapezoid in plan view.

[0056] The roof member 31 of the booth apparatus 1 may be open not only between two side edges opposing in the front-rear direction and the peripheral wall 2 as in this embodiment, but also between two side edges opposing in the left-right direction and the peripheral wall 2. Furthermore, it is also acceptable for three or more side edges in the front-rear and left-right directions to be open between the peripheral wall 2.

[0057] In the booth apparatus 1, the roof member 31, the first louver member 32, and the second louver member 33 are provided as a shielding portion that shields the opening 2a of the peripheral wall 2, but it is also possible to configure the booth apparatus 1 so that only the roof member 31 is provided as a shielding portion. Also, in the booth apparatus 1, it is also possible to configure the shielding portion using only louver members, and to configure the roof member by rotating some of the louver members to be continuous with adjacent louver members.

[0058] In the booth apparatus 1, the roof member 31, first louver member 32, and second louver member 33, which are the shielding parts, are not limited to being made of nonwoven fabric, but may be made of other materials capable of reflecting sound, such as steel plate. It is also possible to form a sound-absorbing panel by inserting sound-absorbing material inside a panel body made of steel plate.

[0059] The booth apparatus 1 may be configured without either or both of the sound-absorbing panels 42 and the speakers S. The booth apparatus 1 may also be configured with the sound-absorbing panels 42 only at the rear or only at the sides. The booth apparatus 1 may also be configured with the speakers S only at the rear.

[0060] In the booth unit 100, it is also possible to install the booth apparatus 1 with the longitudinal direction of the roof member 31 facing the front-to-rear direction. It is also possible to configure the booth apparatus 1 so that the top plate 52 is provided along the side plates 22 (configuration in which the user uses the booth in a position facing the side plates 22).

[0061] [Booth equipment 1A] A booth apparatus 1A according to a second embodiment of the present invention will be described below with reference to Figs. 14 to 20. The booth apparatus 1A according to this embodiment is an example of a private booth according to the present invention. As shown in Figs. 14 to 16, the booth apparatus 1A according to this embodiment is placed on the floor and used for indoor use by one person or a small number of people. Of the components constituting the booth apparatus 1A, those common to the booth apparatus 1 according to the previous embodiment are designated by the same reference numerals and detailed description thereof will be omitted. In this embodiment, the directions of the booth apparatus 1A are defined by the arrows in Fig. 14.

[0062] As shown in FIGS. 14 to 17 , the booth apparatus 1A according to this embodiment, like the booth apparatus 1 according to the previous embodiment, has a cylindrical peripheral wall 2 with an opening 2a formed at the top and in contact with the floor, thereby forming a private room. The peripheral wall 2 is composed of four support posts 120, which are corner supports, and a panel body that is connected by the support posts 120 to form a rectangular shape in a plan view: side panels 22, a door frame panel 23, and a back panel 25. A door 24 is attached to the door frame panel 23 via hinges H so that it can be opened and closed. It is also possible to configure the booth apparatus 1A so that a certain area is formed by connecting panel bodies provided in three directions with the support posts 120. In other words, one side of the booth apparatus 1A may be open, or a configuration without a door 24 or the like may be possible.

[0063] 14 and 16, the support pillars 120 are columnar members arranged at the four corners of the peripheral wall 2, to which the side panels 22, door frame panels 23, doors 24, and back panel 25 are attached. As shown in Figures 18 and 20, the support pillars 120 are formed by assembling locking plates 122, side cover members 123, etc. to a support pillar main body 121.

[0064] As shown in Figure 20, the support main body 121 has protrusions 121a extending in the vertical direction (i.e., the longitudinal direction) that protrude diagonally in the front, rear, left, and right directions and serve as corners of the support main body 121. Furthermore, insertion grooves 121b are formed at the tips of the protrusions 121a along the longitudinal direction. Recessed insertion portions 121c are formed between the protrusions 121a, and these insertion portions 121c are configured as spaces into which connecting members for panel members such as the side panels 22 can be inserted, or into which wiring cords C, etc. can be inserted (see Figure 21).

[0065] 21 , in this embodiment, the pillar main body 121 is formed so that its upper end is lower than the side plate 22 and the back plate 25 so that the wire cord C, which is inserted into the groove 22a on the upper edge of the side plate 22 (the same applies to the groove 25a of the back plate 25), can be passed through the insertion portion 121c without climbing over the pillar main body 121. Furthermore, the upper end of the side cover member 123 is formed at the same height as the upper ends of the side plate 22 and the back plate 25. In other words, the side cover member 123 is formed so that its upper end is located higher than the pillar main body 121. As a result, when the side cover member 123 is assembled to the pillar main body 121, the wire cord C, which is inserted into the insertion portion 121c, can be hidden from view from the outside.

[0066] 19 and 20, the support 120 in this embodiment has a square horizontal cross section that is perpendicular to the longitudinal direction, and has four mounting surfaces that are perpendicular to each other. Specifically, the four mounting surfaces facing the front, back, left, and right directions are formed by surfaces formed by two adjacent protrusions 121a on the support 120. As shown in FIG. 19, each mounting surface on the support 120 can be connected to a panel body such as a side panel 22 or a back panel 25.

[0067] The side panels 22 and the back panel 25 are attached to the mounting surfaces of the support posts 120 via connecting members 22b and 25b fixed to the upper parts of the side panels 22 and the back panel 25. Specifically, as shown in Figure 19, locking portions are formed at the ends of the connecting members 22b and 25b, and these locking portions extend from the end faces of the side panels 22 and the back panel 25. The locking portions are inserted into the insertion portions 121c of the support posts 120, thereby connecting the connecting members 22b and 25b to the support posts 120. The lower parts of the side panels 22 and the back panel 25 are also connected to the support posts 120 in the same way as the upper parts. The door frame panel 23 is also attached to the support posts 120 in the same way as the side panels 22 and the back panel 25.

[0068] 19, in the booth apparatus 1A according to this embodiment, the support pillar 120 is formed so that, in a horizontal cross section, the width dimension of the support pillar 120 in the cutting line direction (left-right direction) of the front mounting surface to which the side plate 22 is attached (support pillar left-right width dimension Ps shown in FIG. 19) is larger than the thickness dimension of the side plate 22 (side plate thickness dimension Ss shown in FIG. 19). Also, in a horizontal cross section, the width dimension of the support pillar 120 in the cutting line direction (front-rear direction) of the left mounting surface to which the back plate 25 is attached (support pillar front-rear width dimension Pb shown in FIG. 19) is larger than the thickness dimension of the back plate 25 (back plate thickness dimension Sb shown in FIG. 19).

[0069] In this embodiment, the support pillar 120 is formed in a square shape in horizontal cross section, so the support pillar left-right width dimension Ps and the support pillar front-rear width dimension Pb are the same dimension. In addition, the side panel thickness dimension Ss and the back panel thickness dimension Sb are the same dimension.

[0070] As shown in Fig. 17, a side cover member 123 is provided on the side surface of the support pillar 120 that is exposed to the outside at the peripheral wall 2. Specifically, as shown in Figs. 18 and 20, an engaging protrusion 123a is formed along the longitudinal direction of the side cover member 123. The engaging protrusion 123a engages with the insertion portion 121c of the support pillar main body 121 via the connecting member 124, thereby assembling the side cover member 123 to the support pillar main body 121.

[0071] As shown in Figure 18, a plate-shaped locking plate 122 is inserted into the insertion groove 121b of the protrusion 121a. A number of locking holes 122b are opened along the longitudinal direction in the locking surface 122a, which is the surface of the locking plate 122. In addition, screw holes 122c are opened in the locking surface 122a. By inserting the locking plate 122 into the insertion groove 121b, locking surfaces 122a are formed that face the four corners of the support 120, front, back, left, and right.

[0072] The locking holes 122b opened in the locking plate 122 are adapted to allow locking portions of brackets to be locked when other components are attached to the support columns 120. Specifically, as shown in FIG. 17, a top-plate support portion 151 for supporting a top plate 152 includes a bracket on which locking claws 151a, which serve as locking portions, are formed. The locking claws 151a, 151a of the top-plate support portion 151 are locked into the locking holes 122b of the support columns 120, thereby assembling the top-plate support portion 151 to each of the two support columns 120 located at the rear of the booth apparatus 1A. The top-plate support portion 151 is fixed to the locking plate 122 by threading fixing screws into the screw holes 122c. This prevents the top-plate support portion 151 from being displaced upward and the locking claws 151a from coming out of the locking holes 122b.

[0073] In addition, the bracket for engaging with the engaging hole 122b is not limited to being provided by the top plate support part 151, and it is also possible to configure the bracket provided on another component to have an engaging claw engaged with the engaging hole 122b.

[0074] 18, in this embodiment, the locking plate 122 is formed to have approximately the same length as the support 120, but it is also possible to form the locking surface 122a by inserting multiple short locking plates into the insertion groove 121b. This makes it possible to insert the locking plate into the insertion groove 121b even if there is not enough space between the ceiling and the support 120 when inserting the locking plate into the support 120 after placing the booth apparatus 1A. In this case, it is sufficient that the short locking plate is inserted into the insertion groove 121b up to the part to be used (the part that locks the bracket), and it is not necessary to insert the locking plate in a stack up to the top of the support 120.

[0075] In the booth apparatus 1A according to this embodiment, the insertion grooves 121b formed in the column main body 121 are inclined at approximately 45 degrees with respect to the mounting surfaces to which the side plates 22 and back plate 25, which are panel bodies, are assembled, as shown in Fig. 20. Therefore, the locking plates 122 inserted into the insertion grooves 121b are mounted to the column main body 121 with the locking surfaces 122a inclined with respect to the mounting surfaces. In other words, between adjacent mounting surfaces in the column 120, locking surfaces 122a inclined with respect to the respective mounting surfaces are formed.

[0076] According to the booth apparatus 1A of this embodiment, as described above, the locking surfaces 122a of the support posts 120 are inclined with respect to the mounting surfaces to which the panel bodies are attached. This makes it possible to make the locking holes 122b of the support posts 120 less visible from inside or outside the booth apparatus 1A, thereby improving the design of the booth apparatus 1A.

[0077] Furthermore, in the booth apparatus 1A according to this embodiment, the support columns 120 are formed so that their widths (the support column left-right width dimension Ps and the support column front-rear width dimension Pb) in the horizontal direction in the cutting line direction of the mounting surface are the same. This allows the thicknesses of the panel bodies connected to the respective mounting surfaces (the side panel thickness dimension Ss of the side panel 22 and the back panel thickness dimension Sb of the back panel 25) to be the same, making it possible to standardize the panel bodies.

[0078] 20, in the booth apparatus 1A according to this embodiment, the support 120 is square in horizontal cross section and has four mounting surfaces that are perpendicular to each other in the front-rear and left-right directions, and a panel body can be connected to each mounting surface. Four locking surfaces 122a are formed between the four mounting surfaces, and are inclined relative to the respective mounting surfaces. Furthermore, each locking surface 122a is formed with a locking hole 122b that can lock a locking portion of a bracket. This makes it possible to connect a panel body to the four mounting surfaces of the support 120, and to form four locking surfaces 122a between the respective mounting surfaces.

[0079] In addition, in the booth apparatus 1A according to this embodiment, the mounting surface of the support 120 can be covered with a side cover member 123, which is a cover member. As shown in the corners of the support 120 in Fig. 19, the gaps between the multiple side cover members 123 are formed as slits through which the locking portions of the brackets can be inserted. This makes it possible to lock the locking portions of the brackets in the locking holes 122b even when the mounting surface of the support 120 is covered with the side cover member 123.

[0080] In the booth apparatus 1A according to this embodiment, the support 120 includes a support main body 121 and a locking plate 122. The support main body 121 is formed with mounting surfaces to which a panel body is attached, and with insertion grooves 121b formed between adjacent mounting surfaces. The locking plate 122 has locking holes 122b formed therein to form locking surfaces 122a, and is assembled to the support main body 121 by being inserted into the insertion grooves 121b. This makes it possible to easily form the locking holes 122b in the support 120 by simply inserting the locking plate 122 into the insertion grooves 121b.

[0081] In the booth apparatus 1A according to this embodiment, the support column 120 has a square horizontal cross section, so that the support column 120 has four mounting surfaces. However, the support column 120 may have at least two mounting surfaces that are perpendicular to each other. In this case, the widths of the support column 120 in the cutting line direction of the two mounting surfaces may be different lengths. Also, like the support column 21 in the booth apparatus 1 described in the first embodiment, the engagement hole 21d may be directly formed in the support column 21 (see the support column 21 according to the first embodiment shown in FIG. 9(b)).

[0082] 15 and 16, on the inner surface of the peripheral wall 2, a plurality of sound-absorbing panels 142 made of a sound-absorbing material such as nonwoven fabric are provided on the rear of the side panels 22 and the back panel 25 (opposite the door 24). In the booth apparatus 1A according to this embodiment, the sound-absorbing panels 142 also absorb the voices of the user inside the booth apparatus 1A, thereby improving the sound insulation of the booth apparatus 1A (attenuation of the volume of sound transmitted between the inside and outside of the booth apparatus 1A). In this embodiment, the plurality of sound-absorbing panels 142 are provided in a vertically divided manner into five panels, each of which is independently attachable to and detachable from the peripheral wall 2.

[0083] The sound-absorbing panel 142 is attached to the side panel 22 and the back panel 25 via a mounting frame 141. The mounting frame 141 is a connecting member interposed between the side panel 22 and the sound-absorbing panel 42, and also functions as an optional mounting member for attaching the speaker Sa. The upper end of the mounting frame 141 is covered by an upper cap 141d.

[0084] In the booth apparatus 1A according to this embodiment, speakers Sa are provided on inner peripheral surfaces (inner surfaces of the side plates 22) that face each other in the left-right direction of the peripheral wall 2. In this embodiment, the front surface of the speaker Sa (the surface facing the user) is formed in a substantially rectangular shape, and almost the entire front surface is configured as an audio output section So. As shown in Fig. 16, the speaker Sa is attached to the side plates 22 via a mounting frame 141, which is an optional mounting member.

[0085] The mounting frame 141, which is an optional mounting member, can be fitted with optional members other than the speaker Sa. For example, in the booth apparatus 1A according to this embodiment, a light I and a display D are attached to the mounting frame 141 that supports the sound-absorbing panel 142 on the back panel 25.

[0086] In the booth apparatus 1A according to this embodiment, a shielding portion is provided at the opening 2a of the peripheral wall 2 via a support member 130, as shown in Figures 14 and 15. In this embodiment, a roof member 131, a first louver member 132, and a second louver member 133 are employed as the shielding portion.

[0087] In the booth apparatus 1A, the support members 130 are engaged with the grooves 22a of the side panels 22 on both the left and right sides. A roof member 131, a first louver member 132, and a second louver member 133 are then placed between the support members 130. In this way, the roof member 131, the first louver member 132, and the second louver member 133 are provided as a shielding section that shields the opening 2a.

[0088] In this embodiment, the roof member 131, first louver member 132, and second louver member 133, which are shielding portions, are configured so that sound-absorbing material such as nonwoven fabric is exposed. Furthermore, the roof member 131, first louver member 132, and second louver member 133, which are shielding portions, are configured so that they shield an area of ​​30% or less of the opening area of ​​the opening 2a in a plan view (a shielding rate of 30% or less). This ensures that water can be sprayed from above by sprinklers or the like in the event of a fire.

[0089] Inside the booth apparatus 1A according to this embodiment, a top plate 152 is provided along the back plate 25. Specifically, as shown in Fig. 15 and Fig. 17, top plate support parts 151 are fixed to the support columns 120, and the top plate 152 is fixed to the upper parts of the two top plate support parts 151, so that the top plate 152 is provided inside the rear part of the booth apparatus 1A (at a position along the back plate 25).

[0090] A curtain 162 capable of shielding the interior of the booth apparatus 1A is provided at the front side of the interior of the booth apparatus 1A. Specifically, as shown in Fig. 16 , a rail 161 capable of suspending the curtain 162 is attached to the door frame panel 23 via an attachment member. The curtain 162 is provided so as to be able to extend and retract while sliding along the rail 161. This allows the interior of the booth apparatus 1A to be shielded by the curtain 162 even when a transparent glass panel is used for the door 24.

[0091] A chair 172 is provided inside the booth apparatus 1A according to this embodiment for a user to sit on when using the top panel 152. In this embodiment, the chair 172 is supported by a chair support member 171 extending from the lower end of the back panel 25, and its position inside the booth apparatus 1A is fixed and invariable.
