Description

[Technical Field]

[0001] The present invention relates to an attachment structure for attaching optional parts to panel materials of booth furniture that can be used for personal office work or tasks, for example in offices, public facilities, etc., and to booth furniture equipped with such an attachment structure. [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 and conferences involving multiple users are often held using personal computers in booths. In these cases, whiteboards are often used to write down the contents of the meeting. For example, the upper end of a mounting bracket can be hooked onto the upper end of a panel material, and a protrusion formed on the backside of the whiteboard can be engaged with the lower end of the mounting bracket to hang the whiteboard from the upper end of the panel material. In this case, if the inner surface of the panel material is flat, the mounting bracket hooked onto the upper end of the panel material may shift left or right from the correct position, causing the whiteboard to tilt.

[0005] Another option is to attach a mounting bracket to the inside surface of the panel material near the bottom edge of the whiteboard and use that mounting bracket to support the bottom edge of the whiteboard from below.However, even in this case, if the inside surface of the panel material is flat, the mounting bracket attached to the inside surface of the panel material may shift vertically from the appropriate position, causing the whiteboard to tilt.

[0006] In addition, in order to prevent sound from leaking from the space inside the booth to the surrounding area, it is possible to attach an upper panel as a roof near the upper end of the panel material, but if there is a gap between the base of the upper panel and the inner surface of the panel material, sound will leak from the space inside the booth to the surrounding area through that gap.

[0007] It is also possible to attach lighting fixtures to the surface of panel materials in the booth space, but if there is a gap between the base of the lighting fixture and the inside surface of the panel material, light from the lighting fixture will leak upward through the gap.It is also possible to install a top plate in the booth space, but if there is a gap between the base of the top plate and the inside surface of the panel material, objects placed on the top plate will fall through the gap.

[0008] In particular, when the panel material used to make up the booth has a structure in which multiple convex portions surrounded by two sets of grooves extending approximately parallel to one another are arranged vertically and horizontally, if the base portions of the upper panel, the lighting fixture, and the tabletop are positioned so as to face the convex portions, gaps are likely to form between these base portions and the grooves between the convex portions.

[0009] The present invention has been made with an eye on these issues, and aims to realize an optional part mounting structure and booth furniture equipped with the same that eliminates the problems that arise when optional parts are attached to panel material. [Means for solving the problem]

[0010] In order to achieve the above object, the present invention takes the following measures.

[0011] In other words, the mounting structure for optional parts of the present invention is a mounting structure for mounting optional parts to a panel material having a structure in which multiple convex parts surrounded by two sets of grooves extending approximately parallel to one another are arranged vertically and horizontally, and is characterized in that at least the vertical grooves between the convex parts of the panel material are arranged in a straight line, and the mounting member that suspends the optional part from the upper end of the panel material is positioned to correspond to the vertical grooves.

[0012] In this way, when an optional part is hung from the upper end of the panel material, the vertical groove can be used to stabilize the position of the mounting member, preventing the optional part from tilting. Also, the mounting member that hangs the optional part is less visible because it is aligned with the vertical groove.

[0013] In the optional component mounting structure of the present invention, it is preferable that the mounting member has a width substantially equal to the thickness of the panel material and has a fitting recess that fits into the upper end of the panel material.

[0014] In this way, the mounting member can be easily suspended from the upper end of the panel material.

[0015] The mounting structure for optional parts of the present invention is a mounting structure for mounting optional parts to a panel material having a structure in which multiple convex parts surrounded by two sets of grooves extending approximately parallel to each other are arranged vertically and horizontally, and is characterized in that at least the horizontal grooves between the convex parts of the panel material are arranged in a straight line, and a mounting member that supports the optional part from below near the surface of the panel material is positioned so as to correspond to the horizontal grooves.

[0016] In this way, when supporting an optional part placed on the surface of the panel material from below, the horizontal groove can be used to stabilize the position of the mounting member, preventing the optional part from tilting. Also, the mounting member supporting the optional part from below is less visible because it is aligned with the horizontal groove.

[0017] In the optional component mounting structure of the present invention, it is preferable that the mounting member is fixed to an outer peripheral groove formed in the end face of the panel material.

[0018] In this way, the mounting position is guided by the outer circumferential groove, so that the mounting member can be easily fixed to the end face of the panel material.

[0019] The mounting structure for optional parts of the present invention is a mounting structure for mounting optional parts to a panel material having a structure in which multiple convex parts surrounded by two sets of grooves extending approximately parallel to each other are arranged vertically and horizontally, and is characterized in that at least the horizontal grooves between the convex parts of the panel material are arranged in a straight line, and the ends of the optional parts are positioned so as to correspond to the horizontal grooves.

[0020] In this way, the gap between the end of the optional part and the surface of the panel material can be reduced.

[0021] In the optional part mounting structure of the present invention, it is preferable that the optional part is an upper panel mounted in the vicinity of the upper end of the panel material.

[0022] This reduces the gap between the base of the upper panel and the surface of the panel material, making it less likely for sound to leak upward from the gap.

[0023] In the optional part mounting structure of the present invention, it is preferable that the optional part is a lighting fixture mounted on the surface of the panel material.

[0024] This reduces the gap between the base of the lighting fixture and the surface of the panel material, making it less likely that light will leak upwards through the gap.

[0025] In the optional part mounting structure of the present invention, it is preferable that the optional part is a top plate placed on a top plate support attached to an end of the panel material.

[0026] In this way, the gap between the edge of the top plate and the surface of the panel material can be made small, making it difficult for objects placed on the top plate to fall through the gap.

[0027] In the optional component mounting structure of the present invention, it is preferable that the convex portion is formed by covering the surface of the sound absorbing material with a tension material.

[0028] In this way, the booth interior space is surrounded by a panel material having a structure in which a plurality of convex portions each having a convex strip of sound-absorbing material arranged on either side of a groove are arranged, and sound generated in the booth interior space is easily absorbed by the panel material. This suppresses sound leakage to the surrounding area, such as what a user says in the booth interior space, and booth furniture with a high sound absorption effect is obtained.

[0029] It is preferable that the booth furniture of the present invention is equipped with an attachment structure for any of the optional parts described above, and that multiple panel materials are connected in a U-shape to form an internal space with at least one side open.

[0030] In this way, the booth interior space is surrounded by a panel material having a structure in which a plurality of convex portions each having a convex strip of sound-absorbing material arranged on either side of a groove are arranged, and sound generated in the booth interior space is easily absorbed by the panel material. This suppresses sound leakage to the surrounding area, such as what a user says in the booth interior space, and booth furniture with a high sound absorption effect is obtained. [Effects of the Invention]

[0031] According to the present invention, it is possible to solve the problems that arise when optional parts are attached to a panel material. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0033] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0034] (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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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 and 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).

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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. In the booth furniture 1 of this embodiment, the horizontal grooves 50 between the block portions (convex portions) 51 of the side panels 10, 11 are aligned in a straight line, and the base portion of the top panel 31 is positioned to correspond to the horizontal grooves 50.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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).

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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).

[0059] 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.

[0060] 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.

[0061] 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.

[0062] In the booth furniture 1 of this embodiment, a whiteboard 501 is attached to the inner surface of the back panel 12, as shown in FIGS.

[0063] Whiteboard 501 is suspended from the upper end of rear panel 12 by two mounting brackets 502. Each of the two mounting brackets 502 is formed by bending a metal rod-shaped member and has approximately the same shape. The two mounting brackets 502 are located near the left and right ends of whiteboard 501.

[0064] 11, the upper end of the front portion 502a of the mounting bracket 502 is bent horizontally toward the rear side to form a horizontal portion 502b, and the rear end of the horizontal portion 502b is bent downward to form a locking portion 502c. The front portion 502a and the locking portion 502c extend vertically and are generally parallel to each other. The distance between the front portion 502a and the locking portion 502c is generally the same as the thickness of the rear panel 12. In other words, the mounting bracket 502 has a width generally the same as the thickness of the rear panel 12 and has a fitting recess 502T that fits into the upper end of the rear panel 12.

[0065] The lower end of front portion 502a of mounting bracket 502 is bent horizontally toward the front side to form horizontal portion 502d, and the front end of horizontal portion 502d is bent upward to form engagement portion 502e. Engagement protrusion 501a is formed on the back surface of whiteboard 501, and engagement portion 502e of mounting bracket 502 engages with engagement protrusion 501a.

[0066] In this way, the upper end of mounting bracket 502 is hooked onto the upper end of rear panel 12, and engaging protrusion 501a formed on the back surface of the whiteboard is engaged with the lower end of mounting bracket 502. As a result, whiteboard 501 is attached within booth space S1, positioned along the inner surface of rear panel 12.

[0067] As described above, the inner surface of rear panel 12 has a structure in which a plurality of block portions (convex portions) 51 surrounded by two sets of grooves 50 extending approximately parallel to one another are arranged vertically and horizontally. The vertical grooves between block portions (convex portions) 51 of rear panel 12 are aligned in a straight line. When whiteboard 501 is hung on the inner surface of rear panel 12, front portion 502a of mounting bracket 502 is positioned to correspond to vertical grooves 50, as shown in FIG. 11(b).

[0068] The lower end of the whiteboard 501 is supported from below by a mounting member 503. As shown in FIG. 12(a), the mounting member 503 is a member that extends substantially horizontally, and brackets 503a are provided on both left and right ends thereof. The brackets 503a are fastened to the left and right ends of the rear panel 12 with bolts (not shown), respectively. As a result, the mounting member 503 is disposed so as to extend substantially horizontally on the inner surface of the rear panel 12 across the entire width of the rear panel 12, as shown in FIG. 12(b).

[0069] Brackets 503a formed on both ends of mounting member 503 are fastened with bolts (not shown) to outer circumferential grooves 60a formed on the left and right ends of rear panel 12. This is similar to the method in which brackets 32 for mounting top panel 31 are fastened with bolts 33 to outer circumferential grooves 60a formed on the front and rear ends of side panel 10.

[0070] In this way, attachment member 503, which is disposed substantially horizontally on the inner surface of rear panel 12, comes into contact with the lower end of whiteboard 501, so that the lower end of whiteboard 501 is supported from below by attachment member 503. The horizontal grooves between block portions (convex portions) 51 of rear panel 12 are aligned in a straight line. When whiteboard 501 is suspended from the inner surface of rear panel 12, the lower end of whiteboard 501 is positioned at substantially the same height as the upper surface of attachment member 503. Therefore, as shown in FIG. 12(b), attachment member 503 is positioned so as to correspond to horizontal groove 50.

[0071] As described above, the booth furniture 1 of this embodiment has an attachment structure for attaching a whiteboard 501 to a back panel 12 having a structure in which multiple convex portions 51 surrounded by two sets of grooves 50 extending approximately parallel to each other are arranged vertically and horizontally, and the vertical grooves 50 between the convex portions 51 of the back panel 12 are aligned in a straight line, and the mounting brackets 502 for hanging the whiteboard 501 from the upper end of the back panel 12 are positioned so as to correspond to the vertical grooves 50.

[0072] In this way, when hanging whiteboard 501 from the upper end of rear panel 12, mounting bracket 502 can be stabilized in position using vertical groove 50. This prevents whiteboard 501 from tilting. Also, mounting bracket 502 for hanging whiteboard 501 is difficult to see because it is aligned with the vertical groove.

[0073] In the booth furniture 1 of this embodiment, the mounting member 502 has a width substantially equal to the thickness of the back panel 12 and has a fitting recess that fits into the upper end of the back panel 12.

[0074] In this way, the mounting member 502 can be easily suspended from the upper end of the back panel 12.

[0075] The booth furniture 1 of this embodiment has an attachment structure for attaching a whiteboard 501 to a back panel 12 having a structure in which multiple convex portions 51 surrounded by two sets of grooves 50 extending approximately parallel to each other are arranged vertically and horizontally, and the horizontal grooves 50 between the convex portions 51 of the back panel 12 are arranged in a straight line, and an attachment member 503 that supports the lower end of the whiteboard 501 from below on the surface of the back panel 12 is positioned so as to correspond to the horizontal grooves 50.

[0076] In this way, when the lower end of whiteboard 501 is supported from below on the surface of rear panel 12, the position of mounting member 503 can be stabilized by utilizing horizontal groove 50. This prevents whiteboard 501 from tilting. Also, mounting member 503 supporting whiteboard 501 from below is difficult to see because it is aligned with horizontal groove 50.

[0077] In the booth furniture 1 of this embodiment, the mounting member 503 is fixed to the outer circumferential groove 60a formed on the end face of the back panel 12.

[0078] In this way, the mounting position is guided by the outer circumferential groove 60a, so that the mounting member 503 can be easily fixed to the end face of the back panel 12.

[0079] The booth furniture 1 of this embodiment has an attachment structure for attaching the top panel 31 to the side panels 10, 11, which have a structure in which multiple convex portions 51 surrounded by two sets of grooves 50 extending approximately parallel to each other are arranged vertically and horizontally, and the horizontal grooves 50 between the convex portions 51 of the side panels 10, 11 are aligned in a straight line, and the base portion of the top panel 31 attached near the upper end of the side panels 10, 11 is positioned so as to correspond to the horizontal grooves 50.

[0080] In this way, the gap between the base of the top panel 31 and the surfaces of the side panels 10 and 11 can be made small, making it difficult for sound to leak upward from the gap.

[0081] In the booth furniture 1 of this embodiment, the convex portion 51 is formed by covering the surface of the sound absorbing material 53 with the upholstery material 54 .

[0082] In this way, the booth interior space S1 is surrounded by the side panels 10, 11 and the back panel 12, which have a structure in which a plurality of convex portions 51 are arranged, each having a convex strip of 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 side panels 10, 11 and the back panel 12. This prevents sound, such as what a user says in the booth interior space S1, from leaking to the surroundings, thereby providing booth furniture with a high sound-absorbing effect.

[0083] (Second embodiment) The booth furniture 101 of this embodiment differs mainly from the booth furniture 1 of the first embodiment in that the booth furniture 1 of the first embodiment is provided with an attachment member 503 that supports the lower end of the whiteboard 501 from below, whereas the booth furniture 101 of this embodiment is not provided with an attachment member 503 that supports the lower end of the whiteboard 501 from below. 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.

[0084] The booth furniture 101 shown in Figures 13 and 14 includes a pair of side panels 110, 111 arranged opposite each other, and a back panel 112 connected between one end (back end) 110a, 111a of these side panels 110, 111, and is U-shaped in plan view as a whole, making it self-standing, and forming an interior booth space S101 that serves as living space inside. 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.

[0085] In the booth furniture 101, as shown in Figures 13 and 14, 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 as to be 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. Furthermore, the lower end of the upper panel 131 contacts the inner surface of the rear panel 112 below the upper end of the rear panel 112. In the booth furniture 101 of this embodiment, the lateral grooves 50 between the block portions (convex portions) 51 of the rear panel 112 are aligned in a straight line, and the base portions of the upper panel 131 are positioned to correspond to the lateral grooves 50.

[0086] In the booth furniture 101, a lighting fixture 135 is attached below the top panel 131. A table 102 is placed inside the booth furniture 101. A top plate 102a of the table 102 is rectangular, and is placed along the inner surfaces of the side panels 110 and 111 and the inner surface of the back panel 112.

[0087] Therefore, brackets 132 for attaching the top panel 131 are provided near the upper ends of the left and right ends of the rear panel 112. This is similar to the first embodiment in which brackets 32 for attaching the top panel 31 are provided near the upper ends of the front and rear ends of the side panels 10 and 11.

[0088] Furthermore, brackets 136 for mounting a lighting fixture 135 are provided on the left and right ends of the rear panel 112. In this embodiment, the brackets for mounting the lighting fixture 135 are integrally provided on both ends of the lighting fixture 135.

[0089] Furthermore, top plate receivers 103 for supporting the top plate 102a of the table 102 are attached near the center in the height direction of the left and right ends of the rear panel 112. The rear end of the top plate 102a of the table 102 is supported at both ends by the top plate receivers 103, and the front end of the top plate 102a is supported at both ends by legs 102c. The two legs 102c are fixed to both ends on the front side of the underside of the top plate 102a, respectively.

[0090] 15, bracket 132, bracket 136, and top plate receiver 103 are attached to the left end of rear panel 112. Bracket 132, bracket 136, and top plate receiver 103 are each fastened with bolts (not shown) to outer circumferential grooves 60a formed in the left end of rear panel 112. The same applies to the right end of rear panel 112.

[0091] 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.

[0092] In booth furniture 101 of this embodiment, as shown in Figures 13 and 14, a whiteboard 501 is attached to the inner surface of side panel 111. Whiteboard 501 is suspended from the upper end of side panel 111 by two mounting brackets 502. The shape of mounting bracket 502 and the method of suspending whiteboard 501 from the upper end of side panel 111 are similar to the shape of mounting bracket 502 of the first embodiment and the method of suspending whiteboard 501 from the upper end of rear panel 12, so detailed description will be omitted.

[0093] Furthermore, in the booth furniture 101 of this embodiment, the horizontal grooves 50 between the block portions (convex portions) 51 of the back panel 12 are aligned in a straight line, and the base portions of the top panel 131 are positioned to correspond to the horizontal grooves 50. In other words, the brackets 132 for attaching the top panel 131 are attached to the edge portions of the back panel 12 so that the base portions of the top panel 131 are positioned to correspond to the horizontal grooves 50.

[0094] Furthermore, in the booth furniture 101 of this embodiment, the horizontal grooves 50 between the block portions (convex portions) 51 of the back panel 12 are aligned in a straight line, and the base portions of the lighting fixtures 135 are positioned to correspond to the horizontal grooves 50. In other words, the brackets 136 for mounting the lighting fixtures 135 are attached to the edge portions of the back panel 12 so that the base portions of the lighting fixtures 135 are positioned to correspond to the horizontal grooves 50.

[0095] Furthermore, in the booth furniture 101 of this embodiment, the horizontal grooves 50 between the block portions (convex portions) 51 of the back panel 12 are aligned in a straight line, and the end of the table top 102a placed on the table top holder 103 is positioned to correspond to the horizontal grooves 50. In other words, the table top holder 103 for supporting the table top 102a of the table 102 is attached to the edge portion of the back panel 12 so that the end of the table top 102a placed on the table top holder 103 is positioned to correspond to the horizontal grooves 50.

[0096] As described above, the booth furniture 101 of this embodiment provides the same effects as the booth furniture 1 of the first embodiment.

[0097] (Third embodiment) The booth furniture 201 of this embodiment differs from the booth furniture 1 of the first embodiment mainly in that the booth furniture 1 of the first embodiment is provided with two upper panels 31, whereas the booth furniture 201 of this embodiment is not provided with an upper panel. 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.

[0098] 16 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 as a whole, 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.

[0099] In the booth furniture 201 of this embodiment, as shown in FIG. 16, two sets of sound-absorbing panels 80A are arranged above the booth interior space S1. Both 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 all have the same configuration and are flat, plate-like members that are substantially 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.

[0100] The sound-absorbing panels 80a to 80c are each suspended from the ceiling via a suspension member 81 so as to be positioned above the booth interior space S1. The sound-absorbing panels 80a to 80c are positioned at different horizontal positions in a plan view. That is, the three sound-absorbing panels 80a to 80c are positioned so as not to overlap each other in a plan view. The three sound-absorbing panels 80a to 80c are also positioned at different heights. That is, the sound-absorbing panel 80a is positioned at the lowest height, followed by the sound-absorbing panels 80b and 80c at higher heights.

[0101] The structure of the sound-absorbing panel 80 will be described with reference to FIG.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 16, in booth furniture 201 of this embodiment, a whiteboard 501 is attached to the inner surface of rear panel 12. Whiteboard 501 is suspended from the upper end of rear panel 12 by two mounting brackets 502, and the lower end of whiteboard 501 is supported from below by mounting members 503. Note that the method of suspending whiteboard 501 from the upper end of rear panel 12 by mounting brackets 502 and the method of supporting the lower end of whiteboard 501 from below by mounting brackets 503 are the same as in the first embodiment, and therefore detailed explanations will be omitted.

[0107] As described above, the booth furniture 201 of this embodiment provides the same effects as the booth furniture 1 of the first embodiment.

[0108] (Fourth embodiment) The booth furniture 301 of this embodiment differs mainly from the booth furniture 1 of the first embodiment in that the booth furniture 1 of the first embodiment is provided with two top panels 31 and front panels 13a, 13b, whereas the booth furniture 301 of this embodiment is not provided with a top panel or a front panel. 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.

[0109] 18 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.

[0110] 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.

[0111] 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. 19 , 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 and fitting the attachment members 81a into the holes 380c in the front end and the attachment members 81b into the holes 380c in the rear end.

[0112] 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.

[0113] 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.

[0114] 18, in booth furniture 301 of this embodiment, a whiteboard 501 is attached to the inner surface of rear panel 12. Whiteboard 501 is suspended from the upper end of rear panel 12 by two mounting brackets 502, and the lower end of whiteboard 501 is supported from below by mounting members 503. Note that the method of suspending whiteboard 501 from the upper end of rear panel 12 by mounting brackets 502 and the method of supporting the lower end of whiteboard 501 from below by mounting brackets 503 are the same as in the first embodiment, and therefore detailed explanations will be omitted.

[0115] As described above, the booth furniture 301 of this embodiment provides the same effects as the booth furniture 1 of the first embodiment.

[0116] Although the embodiments of the present invention have been described above, the configuration of each part is not limited to the above-described embodiments.

[0117] In the first embodiment, the mounting bracket 502 and mounting member 503 for mounting the whiteboard 501 as an optional part to the rear panel 12 have been described, but the present invention is not limited to this.

For example, the top panel 31 may be provided near the upper ends of the side panels 10, 11 and near the upper end of the back panel 12. The top panel 31 may also be provided near the upper ends of the front panels 13a, 13b. In other words, the top panel may be provided near the upper end of at least one of the multiple panel materials of the booth furniture 1. The same applies to the second to fourth embodiments.

[0128] In the first embodiment, the top panel 31 is provided so as to be inclined upward from near the top ends of the side panels 10, 11 as it moves away from the side panels 10, 11, but this is not limiting. For example, the top panel 31 may be provided along the horizontal direction from near the top ends of the side panels 10, 11. The same applies to the second to fourth embodiments.

[0129] In the first embodiment, the front panels 13a, 13b facing the back panel 12 are provided, but this is not limiting. The front panels 13a, 13b do not have to be provided. Also, only one of the front panels 13a, 13b facing the back panel 12 may be provided. The booth furniture 1 of the present invention only needs to include at least the side panels 10, 11 and the back panel 12 connecting the back end portions of the side panels 10, 11. The same applies to the second to fourth embodiments.

[0130] In the first embodiment, the sound absorbing material 53 is made of a soft, elastically deformable material, but this is not limiting. For example, the sound absorbing material 53 may be made of a hard, non-elastically deformable material. The same applies to the second to fourth embodiments.

[0131] In the first embodiment, the surface layer material 63 including the sound absorbing material 53 is fixed to the core material 60 by wrapping the end of the upholstery material 54 in the outer peripheral groove 60a formed on the end face of the core material 60, but this is not limitative. Any method can be used to fix the surface layer material 63 including the sound absorbing material 53 to the core material 60. The same applies to the second to fourth embodiments.

[0132] In the first embodiment, the core material 60 is a paper honeycomb core, but is not limited to this. The material and structure of the core material 60 are arbitrary. The same applies to the second to fourth embodiments.

[0133] In the first embodiment, MDF 61 is provided on one side of core material 60 and MDF 62 is provided on the other side of core material 60, but this is not limiting. MDF may be provided on only one side of core material 60. Furthermore, MDF does not have to be provided on both sides of core material 60.

[0134] In the first embodiment, the block portions 51 having the convex sound-absorbing material 53 on the side panels 10, 11, the back panel 12, and the front panels 13a, 13b are arranged facing the booth interior space S1, but this is not limited to this. The block portions 51 having the convex sound-absorbing material 53 may be arranged facing the outside of the booth interior space S1. Furthermore, the block portions 51 having the convex sound-absorbing material 53 may be arranged facing both the booth interior space S1 and the booth interior space S1. In other words, the convex sound-absorbing material 53 may be provided on both sides of the multiple panel materials of the booth furniture 1. The same applies to the second to fourth embodiments.

[0135] In the first embodiment, the block portions 51 having the convex sound-absorbing material 53 are provided on both sides of the panel material of the upper panel 31, but this is not limited thereto. It is sufficient that the block portions 51 having the convex sound-absorbing material 53 are provided on at least the lower surface of the upper panel 31.

[0136] In the first embodiment, the front panels 13a and 13b are connected to the front end portions 10b and 11b of the side panels 10 and 11, respectively. However, this is not limiting. For example, the left end portion of the front panel 13a may be disposed adjacent to the front end portion 10b of the side panel 10, and the right end portion of the front panel 13b may be disposed adjacent to the front end portion 110b of the side panel 11. In other words, a gap may be formed between the left end portion of the front panel 13a and the front end portion 10b of the side panel 10, or a gap may be formed between the right end portion of the front panel 13b and the front end portion 110b of the side panel 11.

[0137] In the first embodiment, the side panels 10, 11 and the back panel 12 are connected in a U-shape to form an interior space S1 with one side open across the entire height of the booth furniture 1, but this is not limited thereto. The booth furniture of the present invention may be any type in which a plurality of panel materials are connected in a U-shape to form an interior space with at least one side open.
