Description

[Technical Field]

[0001] The present invention relates to booth furniture that can be used in offices, public facilities, etc., suitable for personal office work or tasks. [Background technology]

[0002] In offices, public facilities, etc., booths that include left and right side panels and a back panel that connects one end of these side panels are known as spaces for individual work or tasks (see, for example, Patent Document 1). Inside the booth, a top panel is arranged along the left and right side panels and the back panel, creating a space where users seated facing the top panel can concentrate on their work or tasks without being distracted by their surroundings. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4804939 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, online meetings are often held using personal computers in booths. In these cases, users seated in the booth make various statements while looking at the screen of a personal computer placed on the top panel. The booth described in Patent Document 1 has a problem in that the left and right side panels and back panel are simply made of plate-like members, which causes the sound of what users say to leak to the surrounding area. This problem also occurs when multiple users hold a meeting in a relatively large booth.

[0005] The present invention has been made with a focus on these problems, and aims to realize new booth furniture that makes it possible to suppress sound leakage to the surrounding area. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention takes the following measures.

[0007] In other words, when a pair of upper panels are attached in a V-shape facing each other above the opposing panel materials of a U-shaped booth, the booth furniture of the present invention has a sound-absorbing panel positioned above the space between the pair of upper panels.

[0008] In this way, the sound-absorbing panels are placed above the booth interior space, so that sounds generated within the booth space are easily absorbed by the sound-absorbing panels. This prevents sounds, such as those spoken by users, from leaking from above the booth interior space to the surrounding area, resulting in booth furniture with a high sound-absorbing effect above.

[0009] The booth furniture of the present invention has a sound-absorbing panel disposed above a table top placed inside a U-shaped booth.

[0010] In this way, since the sound-absorbing panel is placed above the table top placed in the booth space, even if sound generated in the booth space is reflected by the table top, it is easily absorbed by the sound-absorbing panel. This prevents sound, such as what a user says in the booth space, from leaking from above to the surrounding area, resulting in booth furniture with a high sound-absorbing effect in the upper part.

[0011] In the booth furniture of the present invention, a sound-absorbing panel is disposed above the area enclosed by the U-shaped booth.

[0012] In this way, the sound-absorbing panels are placed above the booth interior space, so that sounds generated within the booth space are easily absorbed by the sound-absorbing panels. This prevents sounds, such as those spoken by users, from leaking from above the booth interior space to the surrounding area, resulting in booth furniture with a high sound-absorbing effect above.

[0013] In the booth furniture of the present invention, it is preferable that a plurality of U-shaped booths are connected or arranged adjacent to each other, and that sound-absorbing panels are arranged so as to span the range above them.

[0014] In this way, sound leakage from above the plurality of U-shaped booths to the surroundings is suppressed, and booth furniture with a high sound absorption effect above is obtained.

[0015] In the booth furniture of the present invention, it is preferable that the U-shaped booth has a surface made of sound-absorbing material covered with upholstery, on which a block portion is formed, surrounded by two sets of grooves extending approximately parallel to one another, forming a convex strip, and that multiple panel materials having such a structure are connected in a U-shape, and at least one side of the panel materials is open.

[0016] In this way, the interior space of the booth is surrounded by a panel material having a structure in which multiple blocks with convex sound-absorbing material arranged on either side of grooves are arranged, and sound generated in the interior space of the booth is easily absorbed by the panel material. This prevents sound, such as what a user says in the interior space of the booth, from leaking to the surroundings, resulting in booth furniture with high sound absorption properties.

[0017] In the booth furniture of the present invention, it is preferable that the sound-absorbing panel is suspended from above and placed above the area surrounded by the U-shaped booth.

[0018] In this way, the sound-absorbing panel can be easily placed above the U-shaped booth.

[0019] In the booth furniture of the present invention, it is preferable that the underside of the sound-absorbing panel has a structure in which a plurality of block portions are arranged vertically and horizontally on the surface of the sound-absorbing material covered with upholstery, the block portions being surrounded by two sets of grooves extending approximately parallel to one another to form convex strips.

[0020] In this way, the underside of the sound-absorbing panel has a structure in which multiple block sections each having a convex strip of sound-absorbing material arranged on either side of a groove are arranged, so that sound generated in the space inside the booth is easily absorbed by the sound-absorbing panel.

[0021] In the booth furniture of the present invention, it is preferable that a plurality of the sound-absorbing panels are arranged at different horizontal positions.

[0022] In this way, multiple sound-absorbing panels are arranged in a relatively large area at the top of the booth interior space, so that sound traveling upward from the booth interior space can be blocked, thereby increasing the sound absorption effect.

[0023] In the booth furniture of the present invention, it is preferable that a plurality of the sound-absorbing panels are arranged at different height positions.

[0024] In this way, compared to when multiple sound-absorbing panels are arranged at the same height, sound traveling upward from the booth interior space can be blocked without blocking light from above, thereby increasing the sound absorption effect.

[0025] In the booth furniture of the present invention, it is preferable that a plurality of the sound-absorbing panels are arranged substantially parallel to one another.

[0026] In this way, compared to when a large-area sound-absorbing panel is placed at the top of the booth interior space, it is possible to block sound traveling upward from the booth interior space without blocking light from above.

[0027] In the booth furniture of the present invention, it is preferable that the sound-absorbing panel is a tubular member whose upper surface is closed.

[0028] In this way, sound traveling upward from the space inside the booth enters the space inside the sound-absorbing panel, so that the sound traveling upward from the space inside the booth can be blocked, thereby increasing the sound absorption effect. [Effects of the Invention]

[0029] According to the present invention, booth furniture with a high sound absorbing effect can be obtained. [Brief explanation of the drawings]

[0031] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0032] (First embodiment) Fig. 1 is a perspective view of booth furniture 1 according to a first embodiment of the present invention, Fig. 2 is a front view of the booth furniture 1 of Fig. 1, Fig. 3 is a plan view of the first booth, and Fig. 4 is a cross-sectional view of the booth furniture 1 of Fig. 1. Note that the cross-sectional view of Fig. 4 omits illustration of two chairs 2. Fig. 5 is an exploded perspective view of the booth furniture 1, showing only the main components.

[0033] The booth furniture 1 shown in Figures 1 to 4 includes a pair of side panels 10, 11 arranged opposite each other, and a back panel 12 connected between end portions (rear end portions) 10a, 11a of the side panels 10, 11. The entire piece is U-shaped in plan view, making it self-standing and forming an interior booth space S1 that serves as a living space. Two chairs 2 are arranged inside the booth furniture 1. The two chairs 2 are arranged along the inner surfaces of the side panels 10, 11, respectively.

[0034] The side panels 10, 11 and the back panel 12 are each made of panel material of approximately the same shape, forming a horizontally elongated rectangle with a relatively large width. Front panels 13a, 13b are connected to the other ends (front end portions) 10b, 11b of the side panels 10, 11. The front panels 13a, 13b are each made of panel material of approximately the same shape, forming a vertically elongated rectangle with a relatively small width.

[0035] The front panels 13a and 13b are arranged opposite the rear panel 12, and their width is smaller than that of the rear panel 12. Therefore, the space between the front panels 13a and 13b is an opening OP for users to enter and exit the booth space S1. The side panels 10 and 11, the rear panel 12, and the front panels 13a and 13b are set to have the same height.

[0036] 5 and 6, cutouts 10c, 11c, and 12c are formed in the upper ends of both horizontal ends of the side panels 10 and 11 and the back panel 12. Similarly, cutouts 13c, 13c are formed in the upper ends of one horizontal end of the front panels 13a and 13b (the side connected to the side panels 10 and 11).

[0037] The upper ends of the butt corners of the side panels 10, 11 and the back panel 12, the upper ends of the butt corners of the front panel 13a and the side panel 11, and the upper ends of the butt corners of the front panel 13b and the side panel 11 are each connected by fastening bolts 14a using L-shaped connectors 14 in a plan view as a simple connecting means.

[0038] For example, as shown in Fig. 6(a), the upper ends of the butt corners of the side panel 10 and the back panel 12 are connected by fastening bolts 14a with connectors 14 that are L-shaped in plan view placed in cutouts 10c of the side panel 10 and cutouts 12c of the back panel 12. Then, as shown in Fig. 6(b), lids 15 are placed in cutouts 10c of the side panel 10 and cutouts 12c of the back panel 12 to close them.

[0039] Although detailed explanations are omitted, the lower ends of the butt corners of the side panels 10, 11 and the back panel 12, the lower ends of the butt corners of the front panel 13a and the side panel 11, and the lower ends of the butt corners of the front panel 13b and the side panel 11 are also connected by fastening with bolts L-shaped connectors (not shown) in a plan view as a simple connecting means.

[0040] On the sides of the booth furniture 1, covers 16 extending in the vertical direction are attached to the butt corners of the side panels 10, 11 and the back panel 12, the butt corners of the front panel 13a and the side panel 11, and the butt corners of the front panel 13b and the side panel 11.

[0041] Adjusters 3 for adjusting the ground height are attached as grounding members at three equally spaced locations on the lower ends of the side panels 10 and 11, four locations in the center of the back panel, and one location at the end of the opening OP side of the front panels 13a and 13b.

[0042] In the booth furniture 1, as shown in FIGS. 1 and 4, an upper panel 31 is provided above the booth interior space S1, extending from near the upper ends of the side panels 10, 11 toward the inside of the booth interior space S1. The upper panel 31 is inclined so as to be positioned upward as it moves away from near the upper ends of the side panels 10, 11. The upper end of the upper panel 31 is positioned at approximately the same height as the upper ends of the side panels 10, 11. Furthermore, the lower end of the upper panel 31 contacts the inner surfaces of the side panels 10, 11 below the upper ends of the side panels 10, 11. Furthermore, as will be described later, a block portion 51 surrounded by two sets of grooves 50 extending approximately parallel to each other is formed on the inner surface of the back panel 12, and the base portion of the upper panel 31 is positioned to correspond to the grooves 50 extending horizontally on the inner surfaces of the side panels 10, 11.

[0043] Additionally, the top panel 31 is attached to the top of the side panels 10, 11, above two chairs 2 arranged along the inner surfaces of the side panels 10, 11 in the booth interior space S1. The top panel 31 at the top of the side panel 10 is positioned opposite the chair 2 arranged at the bottom of the opposing side panel 11, thereby effectively absorbing the voices of the person sitting in the opposing chair. The top panel 31 at the top of the side panel 11 and the chair 2 at the bottom of the side panel 10 are in the same relationship, and as a result, the booth interior space S1 accommodates two sets of top panels 31 and chairs 2 arranged opposite each other. This provides a sound-absorbing effect that effectively reduces the upward leakage of voices of people talking while seated in the booth.

[0044] 7(a), brackets 32 are provided near the upper ends of the front and rear ends of the side panel 10 to attach the top panel 31. The brackets 32 are fastened with bolts 33 to outer peripheral grooves 60a formed in the front and rear ends of the side panel 10, respectively.

[0045] 7(b), both ends of the top panel 31 are held on brackets 32, so that the top panel 31 is held near the upper end of the side panel 10. The top panel 31 held near the upper end of the side panel 11 is also attached in the same manner.

[0046] The following describes the structures of the side panels 10, 11, rear panel 12, front panels 13a, 13b, and top panel 31. In this embodiment, the structure of the rear panel 12 shown in Fig. 8 will be described in detail, but the structures of the side panels 10, 11, front panels 13a, 13b, and top panel 31 are also similar.

[0047] As shown in Figure 8(a), the inner surface of the rear panel 12 (the surface facing the booth interior space S1) is a panel material having a panel structure in which a plurality of block portions 51 surrounded by two sets of grooves 50 extending approximately parallel to each other are arranged vertically and horizontally via the grooves 50. The block portions 51 have a rectangular shape and are arranged over the entire inner surface of the rear panel 12.

[0048] Specifically, as shown in Figure 8(b), the back panel 12 has a lightweight core material 60 such as paper honeycomb, MDF 61 (Medium Density Fiberboard) provided on one side of the core material 60, MDF 62 provided on the other side of the core material 60, a surface material 63 provided to cover the MDF 61, and an upholstery material (upholstery) 64 provided to cover the MDF 62.

[0049] The core material 60 is a member disposed inside the back panel 12. As described above, the back panel 12 has cutouts 12c formed at both ends of its upper surface, and these cutouts 12c are formed at both ends of the upper end surface of the core material 60. As shown in Figures 9(a) and 9(b), the cutouts 12c have bolt holes 60c formed therein for fastening the connector 14 with bolts 14a.

[0050] A linear circumferential groove 60a is formed on the upper end surface of the core material 60 and is located between two cutout portions 12c. As shown in FIG. 9(b), the peripheral groove 60a is formed in the center of the thickness direction of the core material 60. Similarly, two cutout portions 12c are formed on both ends of the lower end surface of the core material 60, and a peripheral groove 60a is formed between the two cutout portions 12c. Similarly, linear circumferential grooves 60a are formed on the left and right end surfaces of the core material 60 and are located in the center of the thickness direction of the core material 60, as shown in FIG. 9(c).

[0051] 8(b), the surface material 63 is composed of three layers: nonwoven fabric 52 placed on MDF 61, sound-absorbing material (urethane) 53 forming convex stripes, and tension material 54 covering the surface of the sound-absorbing material 53. Therefore, the block portion 51 is composed of the nonwoven fabric 52, sound-absorbing material 53, and tension material 54 in the area surrounded by two sets of grooves 50 extending approximately parallel to each other.

[0052] In this way, the block portion 51 is arranged on only one side of the rear panel 12, and the side on which the block portion 51 is arranged becomes the inner surface of the booth interior space S1. Note that the block portion 51 is also arranged on only one side of the side panels 10, 11 and the front panels 13a, 13b. The block portion 51 is arranged on both sides of the top panel 31.

[0053] 1, the side panels 10, 11, back panel 12 and front panels 13a, 13b are provided with convex sound absorbing materials 53 in the portions facing the booth interior space S1 of the booth furniture 1, and are not provided with convex sound absorbing materials 53 in the portions not facing the booth interior space S1. Note that the top panel 31 is provided with convex sound absorbing materials 53 in the portions facing the booth interior space S1 of the booth furniture 1 and in the portions not facing the booth interior space S1.

[0054] The procedure for providing the surface layer material 63 having the above-described three-layer structure so as to cover the MDF 61 provided on the core material 60 will be described with reference to FIG.

[0055] The surface layer material 63 has a three-layer structure of nonwoven fabric 52, sound-absorbing material 53, and upholstery material 54, and is formed to be longer than the length of the core material 60. Therefore, the surface layer material 63 is cut according to the length of the core material 60, such as the back panel 12, before use.

[0056] First, the surface material 63 is brought close to the MDF 61 provided on the core material 60, and it is confirmed that the groove 50A at the end of the block portion 51 is aligned along the end 60A of the core material 60, as shown in Figure 10(a).

[0057] 10(b), the nonwoven fabric 52 and the sound-absorbing material 53 are cut along the groove 50A at the end of the block portion 51. At this time, the stretching material 54 is not cut along the groove 50A at the end of the block portion 51. As a result, the stretching material 54 covering the surface of the block portion 51 extends outward beyond the end 60A of the core material 60. As will be described later, the stretching material 54 is cut to a length that allows its end to be pushed into the peripheral groove 60a formed in the end face of the core material 60.

[0058] The surface layer material 63, which is made by cutting the nonwoven fabric 52 and sound-absorbing material 53 according to the length of the core material 60, is placed on the surface of the MDF 61 provided on the core material 60 so that the groove 50A at the end of the block portion 51 is aligned with the end 60A of the core material 60. In this state, as shown in Figure 10(c), the end of the upholstery material 54 is pressed into the peripheral groove 60a formed on the end face of the core material 60. This causes the surface layer material 63 to be attached tightly to the surface of the MDF 61 provided on the core material 60.

[0059] The same procedure is followed for providing the upholstery material 64 to cover the MDF 62 provided on the core material 60 on the surface opposite to the surface on which the surface layer material 63 of the core material 60 is provided. That is, the upholstery material 64 is cut to the length of the core material 60, and the upholstery material 64 is placed on the surface of the MDF 62 provided on the core material 60. In this state, the end of the upholstery material 64 is pressed into the peripheral groove 60a formed on the end face of the core material 60. This causes the upholstery material 64 to be attached tightly to the surface of the MDF 62 provided on the core material 60.

[0060] In the booth furniture 1 of this embodiment, as shown in Figures 1 to 3, three sound-absorbing panels 80a to 80c are arranged above the booth interior space S1. The sound-absorbing panels 80a to 80c all have the same configuration and are flat plate-like members that are approximately circular in plan view. In the following description, each of the sound-absorbing panels 80a to 80c may be simply referred to as the sound-absorbing panel 80.

[0061] Two mounting members 81a and 81b are arranged approximately in parallel between the vicinity of the center of the upper end of the side panel 10 and the vicinity of the center of the upper end of the side panel 11. The mounting member 81a is arranged on the front side, and the mounting member 81b is arranged on the rear side of the booth furniture 1 relative to the mounting member 81a.

[0062] The sound absorbing panel 80a is suspended from a mounting member 81a via a suspension member 82, and the sound absorbing panels 80b and 80c are each suspended from a mounting member 81b via a suspension member 82.

[0063] The sound-absorbing panels 80a to 80c are arranged above and near the center of the booth interior space S1. That is, the sound-absorbing panels 80a to 80c are arranged between the two upper panels 31 in a plan view. The sound-absorbing panels 80a to 80c are arranged at different horizontal positions in a plan view. That is, the three sound-absorbing panels 80a to 80c are arranged so that they do not overlap in a plan view. The three sound-absorbing panels 80a to 80c are also arranged at different heights. That is, the sound-absorbing panel 80a is arranged at the lowest height position, followed by the sound-absorbing panels 80b and 80c at higher height positions.

[0064] The structure of the sound-absorbing panel 80 will be described with reference to FIG.

[0065] The sound-absorbing panel 80 is formed in a substantially circular, flat plate shape. The sound-absorbing panel 80 is configured in the same manner as the above-mentioned back panel 12. That is, the lower surface of the sound-absorbing panel 80 (the surface facing the booth interior space S1) is a panel material having a panel structure in which a plurality of block portions 51, each surrounded by two sets of grooves 50 extending substantially parallel to one another, are arranged vertically and horizontally with the grooves 50 interposed therebetween. The block portions 51 are rectangular and are arranged over the entire lower surface of the sound-absorbing panel 80.

[0066] Specifically, similar to the back panel 12 described above, the sound-absorbing panel 80 has a lightweight core material 60 such as paper honeycomb, MDF 61 (Medium Density Fiberboard) provided on one side of the core material 60, MDF 62 provided on the other side of the core material 60, a surface material 63 provided to cover the MDF 61, and an upholstery material (upholstery) 64 provided to cover the MDF 62.

[0067] The surface material 63 is composed of three layers: nonwoven fabric 52 placed on MDF 61, sound-absorbing material (urethane) 53 forming convex stripes, and tension material 54 covering the surface of the sound-absorbing material 53. Therefore, the block portion 51 is composed of the nonwoven fabric 52, sound-absorbing material 53, and tension material 54 in the area surrounded by two sets of grooves 50 extending approximately parallel to each other.

[0068] As described above, in the booth furniture 1 of this embodiment, when a pair of upper panels 31 are attached in a V-shape facing each other above the opposing side panels 10, 11 of the U-shaped booth, the sound-absorbing panel 80 is positioned above the space between the pair of upper panels 31.

[0069] In this way, the sound-absorbing panel 80 is disposed above the booth interior space S1, and sound generated in the booth interior space S1 is easily absorbed by the sound-absorbing panel 80. This prevents sound, such as what a user says in the booth interior space S1, from leaking from above the booth interior space S1 to the surrounding area, thereby providing booth furniture with a high sound-absorbing effect above.

[0070] In the booth furniture 1 of this embodiment, the U-shaped booth has a block portion 51 formed on the surface of a sound-absorbing material 53 covered with upholstery material 54, surrounded by two sets of grooves 50 extending approximately parallel to one another, forming a convex strip, and side panels 10, 11 and a back panel 12, which have a structure in which multiple panels are arranged vertically and horizontally, are connected in a U-shape to form an internal space S1 with at least one side open.

[0071] In this way, the booth interior space S1 is surrounded by a panel material having a structure in which a plurality of block sections 51 are arranged, each having a convex sound-absorbing material 53 arranged on either side of a groove 50, and sound generated in the booth interior space S1 is easily absorbed by the panel material. This prevents sound, such as what a user says in the booth interior space S1, from leaking to the surrounding area, thereby providing booth furniture with a high sound-absorbing effect.

[0072] In the booth furniture 1 of this embodiment, the sound absorbing panels 80a to 80c are suspended from above and disposed above the U-shaped booth.

[0073] In this way, the sound absorbing panels 80a to 80c can be easily arranged above the U-shaped booth.

[0074] In the booth furniture 1 of this embodiment, the underside of the sound-absorbing panels 80a to 80c has a structure in which a plurality of block portions 51 are formed vertically and horizontally on the surface of the sound-absorbing material 53 covered with upholstery material 54, and the block portions 51 are surrounded by two sets of grooves 50 extending approximately parallel to each other, forming convex strips.

[0075] In this way, the undersides of the sound-absorbing panels 80a to 80c have a structure in which multiple block portions 51 having convex sound-absorbing material 53 are arranged, so that sound generated in the booth interior space S1 is easily absorbed by the sound-absorbing panels 80a to 80c.

[0076] In the booth furniture 1 of this embodiment, the sound absorbing panels 80a to 80c are arranged at different horizontal positions.

[0077] In this way, the sound absorbing panels 80a to 80c are arranged in a portion with a relatively large area above the booth interior space s1, and therefore, sound traveling upward from the booth interior space S1 can be blocked, thereby improving the sound absorbing effect.

[0078] In the booth furniture 1 of this embodiment, the sound absorbing panels 80a to 80c are arranged at different height positions.

[0079] In this way, compared to when the sound absorbing panels 80a to 80c are arranged at the same height, it is possible to block sound going upward from the booth interior space S1 without blocking light from above.

[0080] (Second embodiment) The booth furniture 101 of this embodiment differs from the booth furniture 1 of the first embodiment mainly in that, in the booth furniture 1 of the first embodiment, three sound absorbing panels 80a to 80c are arranged above the booth interior space S1, whereas in the booth furniture 101 of this embodiment, one sound absorbing panel 180 is arranged above the booth interior space S101. Detailed description of parts of the configuration of the booth furniture 101 of this embodiment that are similar to the configuration of the booth furniture 1 of the first embodiment will be omitted.

[0081] 12 and 13 includes a pair of side panels 110, 111 arranged opposite each other, and a rear panel 112 connected between end portions (rear end portions) 110a, 111a of the side panels 110, 111. The entirety is U-shaped in plan view, making it self-standing and forming an interior booth space S101 that serves as a living space. A table 102 is arranged inside the booth furniture 101. A top plate 102a of the table 102 is rectangular and is arranged along the inner surfaces of the side panels 110, 111 and the inner surface of the rear panel 112.

[0082] The widths of the side panels 110, 111 and the rear panel 112 are smaller than the widths of the side panels 10, 11 and the rear panel 12 of the first embodiment. The structures of the side panels 110, 111 and the rear panel 112 are substantially the same as the structures of the side panels 10, 11 and the rear panel 12 of the first embodiment.

[0083] In the booth furniture 101, as shown in Figures 12 and 13, an upper panel 131 is provided above the booth interior space S101, extending from near the upper end of the rear panel 112 toward the inside of the booth interior space S101. The upper panel 131 is inclined so that it is positioned upward as it moves away from the rear panel 112. The upper end of the upper panel 131 is positioned at approximately the same height as the upper end of the rear panel 112. In addition, the lower end of the upper panel 131 is in contact with the inner surface of the rear panel 112 below the upper end of the rear panel 112.

[0084] In the booth furniture 101, an upper panel 131 is disposed near the upper end of the rear panel 112, as shown in Fig. 12. In order to attach the upper panel 131, brackets (not shown) are provided near the upper ends of the left and right ends of the rear panel 112, as in the first embodiment. Both ends of the upper panel 131 are held on the brackets, so that the upper panel 131 is held near the upper end of the rear panel 112.

[0085] The top panel 131 is attached to the top of the back panel 112, which is above the top plate 102a of the table 102 arranged along the inner surface of the back panel 112 of the booth space S110. By being positioned above the top plate 102a, the top panel 131 on the top of the back panel 112 effectively absorbs the voice of the person sitting in the chair in front of the table 102 that is reflected upward by the top plate 102a. This provides a sound absorption effect that effectively reduces the voices of people talking in a web conference or the like while seated in the booth from leaking upward.

[0086] In the booth furniture 101 of this embodiment, one sound-absorbing panel 180 is arranged above the booth interior space S101. The sound-absorbing panel 180 has the same configuration as the sound-absorbing panel 80 of the first embodiment, and therefore a detailed description thereof will be omitted.

[0087] A single mounting member 181 is bridged between the vicinity of the center of the upper end of the side panel 110 and the vicinity of the center of the upper end of the side panel 111. The sound-absorbing panel 180 is suspended from the mounting member 181 via a hanging member 182. The sound-absorbing panel 180c is placed above the top board 151 of the table 150 placed inside the booth furniture 101. Therefore, as shown in FIG. 13 , the sound-absorbing panel 180 is placed so as to overlap the top board 151 in a plan view.

[0088] As described above, in the booth furniture 101 of this embodiment, a sound-absorbing panel is placed above a table top placed in a U-shaped booth.

[0089] In this way, since the sound-absorbing panel is placed above the table top placed in the booth space, even if sound generated in the booth space is reflected by the table top, it is easily absorbed by the sound-absorbing panel. This prevents sound, such as what a user says in the booth space, from leaking from above to the surrounding area, resulting in booth furniture with a high sound-absorbing effect in the upper part.

[0090] Furthermore, the booth furniture 101 of this embodiment provides the same effects as the booth furniture 1 of the first embodiment.

[0091] (Third embodiment) The booth furniture 201 of this embodiment differs from the booth furniture 1 of the first embodiment mainly in that, in the booth furniture 1 of the first embodiment, three sound-absorbing panels 80a to 80c are arranged above the booth interior space S1, whereas in the booth furniture 101 of this embodiment, two sets of three sound-absorbing panels 80a to 80c are arranged above the booth interior space S1. Detailed description of parts of the configuration of the booth furniture 201 of this embodiment that are similar to the configuration of the booth furniture 1 of the first embodiment will be omitted.

[0092] The booth furniture 201 shown in Fig. 14 includes a pair of side panels 10, 11 arranged opposite each other and a rear panel 12 connected between end portions (rear end portions) 10a, 11a of the side panels 10, 11, and is U-shaped in plan view, making it self-standing and forming an interior booth space S1 that serves as a living space. A table 202 having a top panel 202a is arranged inside the booth furniture 201. The table 202 is arranged in approximately the center of the interior booth space S1.

[0093] In the booth furniture 201 of this embodiment, as shown in Fig. 14, two sets of sound-absorbing panels 80A are arranged above the booth interior space S1. The two sets of sound-absorbing panels 80A have substantially the same configuration. Each set of sound-absorbing panels 80A includes three sound-absorbing panels 80a to 80c. The sound-absorbing panels 80a to 80c are each suspended from the ceiling via a suspension member 82. The sound-absorbing panels 80a to 80c have the same configuration as the sound-absorbing panel 80 of the first embodiment, and therefore detailed description thereof will be omitted.

[0094] As described above, in the booth furniture 201 of this embodiment, a plurality of sound-absorbing panels 80 are arranged above the top plate 202a of the table 202 installed in the booth interior space S1. Therefore, the voices of the occupants seated around the table 202 in the booth furniture 201 are reflected upward by the top plate 202a and are effectively absorbed by the sound-absorbing panels 80.

[0095] In the booth furniture of the present invention, a sound-absorbing panel is disposed above the area enclosed by the U-shaped booth.

[0096] In this way, the sound-absorbing panels are placed above the booth interior space S1, so that sound generated in the booth interior space S1 is easily absorbed by the sound-absorbing panels. This prevents sound, such as what a user says in the booth interior space S1, from leaking from above the booth interior space S1 to the surrounding area, resulting in booth furniture with a high sound-absorbing effect above.

[0097] Furthermore, the booth furniture 201 of this embodiment provides the same effects as the booth furniture 1 of the first embodiment.

[0098] (Fourth embodiment) The booth furniture 301 of this embodiment differs from the booth furniture 1 of the first embodiment mainly in that, while the sound-absorbing panel 80 of the booth furniture 1 of the first embodiment is a substantially circular flat plate-like member, the sound-absorbing panels 380a, 380b of the booth furniture 101 of this embodiment are long flat plate-like members. Detailed description of parts of the configuration of the booth furniture 301 of this embodiment that are similar to the configuration of the booth furniture 1 of the first embodiment will be omitted.

[0099] 15 includes a pair of side panels 10, 11 arranged opposite each other and a rear panel 12 connected between end portions (rear end portions) 10a, 11a of the side panels 10, 11, and is U-shaped in plan view, making it self-standing and forming an interior booth space S1 that serves as a living space. A table 302 having a top panel 302a is arranged inside the booth furniture 301. The table 302 is arranged in approximately the center of the interior booth space S1.

[0100] Two mounting members 81a and 81b are arranged approximately in parallel between the vicinity of the center of the upper end of the side panel 10 and the vicinity of the center of the upper end of the side panel 11. The mounting member 81a is arranged on the front side, and the mounting member 81b is arranged on the rear side of the booth furniture 1 relative to the mounting member 81a.

[0101] In the booth furniture 301 of this embodiment, four sound-absorbing panels 380a and four sound-absorbing panels 380b are arranged above the booth interior space S1. The four sound-absorbing panels 380a and the four sound-absorbing panels 380b are all arranged at approximately the same height. As shown in FIG. 16 , the sound-absorbing panels 380a and 380b each have a hole 380c formed in the front end and a hole 380c formed in the rear end. Therefore, the sound-absorbing panels 380a and 380b are supported by inserting the attachment member 81a into the hole 380c at the front end and the attachment member 81b into the hole 380c at the rear end.

[0102] The sound-absorbing panels 380a, 380b are both elongated flat members having a predetermined length. The sound-absorbing panels 380a and 380b are arranged alternately and approximately parallel to each other in a direction from the side panel 10 toward the side panel 11. When the booth furniture 301 is viewed from the front, the sound-absorbing panel 380a is inclined so that its right end is positioned higher than its left end, and the sound-absorbing panel 380b is inclined so that its left end is positioned higher than its right end.

[0103] As described above, in the booth furniture 301 of this embodiment, the sound-absorbing panels 380a, 380b are supported with a gap between them on the mounting members 81a, 81b that are bridged across the upper ends of the opposing side panels 10, 11. As a result, the sound-absorbing panels 380a, 380b are disposed with a gap between them above the top plate 302a of the table 302 installed in the booth interior space S1. Therefore, the voices of the occupants seated around the table 302 in the booth furniture 301 that are reflected upward by the top plate 302a are effectively absorbed by the sound-absorbing panels 380a, 380b.

[0104] In the booth furniture of this embodiment, a plurality of sound-absorbing panels are arranged substantially parallel to one another.

[0105] In this way, compared to when a large-area sound-absorbing panel is placed at the top of the booth interior space, it is possible to block sound traveling upward from the booth interior space without blocking light from above.

[0106] Furthermore, the booth furniture 301 of this embodiment provides the same effects as the booth furniture 1 of the first embodiment.

[0107] (Fifth embodiment) The booth furniture 401 of this embodiment differs mainly from the booth furniture 1 of the first embodiment in that the sound-absorbing panels 80 of the booth furniture 1 of the first embodiment are substantially circular, flat-plate-like members, whereas the sound-absorbing panels 480 of the booth furniture 301 of this embodiment are substantially cylindrical members. Detailed description of parts of the configuration of the booth furniture 401 of this embodiment that are similar to the configuration of the booth furniture 1 of the first embodiment will be omitted.

[0108] In the booth furniture 401 of this embodiment, one sound-absorbing panel 480 is disposed above the booth interior space S1. The sound-absorbing panel 480 is a substantially cylindrical member having a predetermined height, and a hollow portion 480A is formed therein. The upper surface 480a of the sound-absorbing panel 480 is closed by a circular plate-like member, and the lower surface 480b is formed in an annular shape. The diameter of the upper surface 480a of the sound-absorbing panel 480 is smaller than the diameter of the lower surface 480b. Therefore, the horizontal cross-sectional area of ​​the hollow portion 480A formed in the sound-absorbing panel 480 increases from top to bottom. A table 402 is disposed inside the booth furniture 401. The top plate 402a of the table 402 is rectangular and is disposed in approximately the center of the booth interior space S1. Therefore, the sound-absorbing panel 480 is disposed above the top plate 402a of the table 402 disposed in the booth furniture 401.

[0109] As described above, in the booth furniture 401 of this embodiment, the sound absorbing panel 480 is a cylindrical member whose upper surface is closed.

[0110] In this way, sound traveling upward from the booth interior space S1 enters the space inside the sound-absorbing panel 480, so that sound traveling upward from the booth interior space S1 can be blocked, thereby improving the sound absorption effect.

[0111] Furthermore, the booth furniture 401 of this embodiment provides the same effects as the booth furniture 1 of the first embodiment.

[0112] (Sixth embodiment) The booth furniture 501 of this embodiment differs mainly from the booth furniture 1 of the first embodiment in that, while the sound-absorbing panels 80 of the booth furniture 1 of the first embodiment are substantially circular flat plate-like members, the sound-absorbing panels 580 of the booth furniture 501 of this embodiment are substantially polygonal flat plate-like members. Detailed description of parts of the configuration of the booth furniture 501 of this embodiment that are similar to the configuration of the booth furniture 1 of the first embodiment will be omitted.

[0113] In the booth furniture 501 of this embodiment, three sound-absorbing panels 580a to 580c are arranged above the booth interior space S1. The sound-absorbing panels 580a to 580c are flat, generally polygonal members, but have different shapes when viewed from above. In the following description, each of the sound-absorbing panels 580a to 580c may be simply referred to as the sound-absorbing panel 580.

[0114] The sound-absorbing panel 580a is suspended from a mounting member 581a via a suspension member 582, and the sound-absorbing panels 580b and 580c are suspended from a mounting member 581b via suspension members 582. The arrangement of the sound-absorbing panels 580a to 580c is similar to that of the sound-absorbing panels 80a to 80c in the first embodiment, and therefore a detailed description will be omitted. A table 502 is placed inside the booth furniture 501. A top plate 502a of the table 502 is rectangular and is placed approximately in the center of the booth interior space S1. Therefore, the sound-absorbing panel 580 is placed above the top plate 502a of the table 502 placed inside the booth furniture 501.

[0115] As described above, the booth furniture 501 of this embodiment can provide the same effects as the booth furniture 1 of the first embodiment.
