Summary of the Invention

Problems to be Solved by the Invention

[0004] As booth furniture provided with panel materials, for example, those including a pair of side panels arranged opposite each other and a back panel connected between one ends of these side panels can be considered. The booth furniture is made self-supporting by forming a U-shape in plan view as a whole, and forms a booth inner space that becomes a living space inside. In the booth furniture, a curved cover is attached to the butting corner portion where the side panel and the back panel are connected at a right angle.

[0005] In addition, multiple booth furniture may be combined and used as a booth unit. For example, in a booth unit where two booth furniture are arranged vertically in series, when the back panel is shared by one panel material, two side panels are connected to the back panel in a substantially T shape. In this case, a flat cover is attached to the butting corner portion where the two side panels and the back panel are connected.

[0006] Therefore, a structure is required to easily attach option parts such as a curved cover or a flat cover to the edge of the panel material.

[0007] The present invention has been made paying attention to these problems, and an object thereof is to realize a new panel furniture and booth furniture that enable easy attachment of option parts to the edge of the panel material.

Means for Solving the Problems

[0008] In order to achieve such an object, the present invention has taken the following means.

[0009] That is, the panel furniture of the present invention is detachable from the edge of the panel material, and has a fixture for attaching an option part from a direction of 90 degrees or 135 degrees with respect to the panel surface of the panel material. The fixture has first to third legs extending radially in three directions from the central portion, and the second and third legs extend in the 90-degree direction and the 135-degree direction with respect to the first leg, respectively.

[0010] By doing so, the option part can be easily attached to the edge of the panel material via the fixture.

[0011] In the panel furniture of the present invention, it preferably has a longitudinal outer peripheral groove formed at the left and right edges of the panel material, and at least one of the legs of the fixture has a plate shape that is inserted into this longitudinal outer peripheral groove.

[0012] By doing so, when attaching the fixture to the edge portion of the panel material, the fixture can be firmly fixed to the edge portion of the panel material by inserting the plate-shaped leg portion. Further, the attachment position of the fixture can be guided by the outer peripheral groove formed in the left and right edge portions of the panel material.

[0013] In the panel furniture of the present invention, it is preferable that the fixture has legs at positions 90 degrees and further 135 degrees in the same direction with respect to the first leg portion, and has a symmetrical shape when turned upside down.

[0014] By doing so, since the fixture is configured to have a symmetrical shape when turned upside down, the same fixture can be used on the left and right.

[0015] In the panel furniture of the present invention, it is preferable that the optional component is a cover in which two sets of engagement portions having a U-shaped cross section are arranged in parallel as engagement portions to the legs of the fixture.

[0016] By doing so, the fixture and the optional component can be attached only by inserting the engagement portion of the optional component into the leg portion of the fixture from one direction.

[0017] In the panel furniture of the present invention, it is preferable that the optional component is a cover attached to the butting corner portion of two panel materials connected at a right angle.

[0018] By doing so, the cover can be easily attached to the butting corner portion of two panel materials connected at a right angle.

[0019] In the panel furniture of the present invention, it is preferable that the optional component is a cover attached to the butting corner portion of three panel materials connected in a substantially T shape.

[0020] By doing so, the cover can be easily attached to the butting corner portion of three panel materials connected in a substantially T shape.

[0021] In the panel furniture of the present invention, when the cover is attached to the butted corner portion, it is preferable that the fixture is covered by the cover and becomes invisible from the outside.

[0022] By doing so, since the fixture is covered by the cover and becomes invisible from the outside, the appearance of the butted corner portion is improved.

[0023] In the panel furniture of the present invention, the upper end portions of the panel materials adjacent to each other in the butted corner portion are connected by a connecting tool, and a locking projection that is locked to the upper surface of the connecting tool in a state of being attached to the butted corner portion is formed on the inner surface of the cover. It is preferable that

[0024] By doing so, in a state where the cover is attached to the butted corner portion, it is possible to prevent the cover from moving downward.

[0025] The booth furniture of the present invention is characterized in that a plurality of the above-described panel furniture are connected in a U-shape to form an internal space with at least one side open.

[0026] By doing so, option parts can be easily attached to the edge portions of the panel furniture included in the booth furniture via fixtures.

Effect of the Invention

[0027] According to the present invention, option parts can be easily attached to the edge portions of the panel materials.

Embodiments for Carrying Out the Invention

[0029] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0030] (First Embodiment) FIG. 1 is a perspective view of the booth furniture 1 according to the first embodiment of the present invention, FIG. 2 is a front view of the booth furniture 1 in 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 in FIG. 1. In the cross-sectional view of FIG. 4, the illustration of the two chairs 2 is omitted. FIG. 5 is an exploded perspective view of the booth furniture 1, but only the main components are shown.

[0031] The booth furniture 1 shown in FIGS. 1 to 4 includes a pair of side panels 10 and 11 arranged opposite to each other, and a rear panel 12 connected between one ends (rear side ends) 10a and 11a of these side panels 10 and 11. The whole is made self-supporting by forming a U-shape in plan view, and forms a booth inner space S1 that becomes a living space inside. Two chairs 2 are arranged inside the booth furniture 1. The two chairs 2 are respectively arranged along the inner surfaces of the side panels 10 and 11.

[0032] The side panels 10 and 11 and the rear panel 12 are respectively panel materials of substantially the same shape, and form a horizontally long rectangular shape with a relatively large width. Front panels 13a and 13b are connected to the other ends (front side ends) 10b and 11b of the side panels 10 and 11. The front panels 13a and 13b are respectively panel materials of substantially the same shape, and form a vertically long rectangular shape with a relatively small width.

[0033] The front panels 13a and 13b are arranged to face the rear panel 12, and their widths are smaller than the width of the rear panel 12. Therefore, an opening OP is provided between the front panels 13a and 13b for users to enter and exit the space S1 inside the booth. The side panels 10, 11, the rear panel 12, and the front panels 13a, 13b are set to the same height dimension.

[0034] Notches 10c, 11c, and 12c are formed at the upper ends of both horizontal ends of the side panels 10, 11 and the rear panel 12, as shown in FIGS. 5 and 6. Similarly, notches 13c, 13c are also formed at the upper ends of one horizontal side (the side connected to the side panels 10, 11) of the front panels 13a, 13b.

[0035] The upper ends between the butting corner portions of the side panels 10, 11 and the rear panel 12, the upper ends between the butting corner portions of the front panel 13a and the side panel 11, and the upper ends between the butting corner portions of the front panel 13b and the side panel 11 are respectively connected by fixing an L-shaped connector 14 in plan view as a simple connecting means with bolts 14a.

[0036] For example, between the upper ends of the butting corner portion of the side panel 10 and the rear panel 12, as shown in FIG. 6(a), the L-shaped connector 14 in plan view is arranged in the notch 10c of the side panel 10 and the notch 12c of the rear panel 12 and fixed with bolts 14a to be connected. Then, as shown in FIG. 6(b), the notch 10c of the side panel 10 and the notch 12c of the rear panel 12 are blocked by arranging a lid portion 15 therein.

[0037] Although detailed description is omitted, the lower ends between the butting corner portions of the side panels 10, 11 and the rear panel 12, the lower ends between the butting corner portions of the front panel 13a and the side panel 11, and the lower ends between the butting corner portions of the front panel 13b and the side panel 11 are similarly connected by fixing an L-shaped connector (not shown in the figure) in plan view as a simple connecting means with bolts.

[0038] On the side of the booth furniture 1, at the butting corner part of the side panels 10, 11 and the back panel 12, at the butting corner part of the front panel 13a and the side panel 11, and at the butting corner part of the front panel 13b and the side panel 11, a cover (end cover) 16 extending in the vertical direction is attached.

[0039] At three positions at equal intervals at the lower ends of the side panels 10, 11 respectively, at four positions at the center of the back panel, and at one position at the end on the opening OP side of the front panels 13a, 13b, an adjuster 3 for adjusting the grounding height is attached as a grounding member.

[0040] In the booth furniture 1, above the booth inner space S1, as shown in FIGS. 1 and 4, an upper surface panel 31 extending from near the upper ends of the side panels 10, 11 toward the inside of the booth inner space S1 is provided. The upper surface panel 31 is inclined so as to be arranged upward as it is separated from near the upper ends of the side panels 10, 11. The upper end portion of the upper surface panel 31 is arranged at substantially the same height as the upper ends of the side panels 10, 11. Also, the lower end portion of the upper surface panel 31 is in contact with the inner surfaces of the side panels 10, 11 below the upper ends of the side panels 10, 11. Further, as will be described later, on the inner surface of the back panel 12, a block portion 51 surrounded by two sets of grooves 50 extending substantially in parallel is formed, and the base portion of the upper surface panel 31 is positioned so as to correspond to the grooves 50 extending in the horizontal direction on the inner surfaces of the side panels 10, 11.

[0041] Further, the upper surface panel 31 is attached to the upper portions of the side panels 10 and 11 along the inner surfaces of the side panels 10 and 11 of the space S1 inside the booth, above the two chairs 2 arranged along the inner surfaces. The upper surface panel 31 on the upper portion of the side panel 10 is in a positional relationship facing the chair 2 arranged at the lower portion of the opposing side panel 11, thereby effectively absorbing the voices of the seated persons on the opposing chairs. The upper surface panel 31 on the upper portion of the side panel 11 and the chair 2 on the lower portion of the side panel 10 are also in the same relationship, and two sets of the combination of the upper surface panel 31 and the chair 2 arranged opposite to each other are accommodated in the space S1 inside the booth. As described above, a sound absorption effect is obtained that effectively reduces the leakage of the voices of people conversing while seated inside the booth upward.

[0042] In order to attach the upper surface panel 31, as shown in FIG. 7(a), brackets 32 are provided near the upper ends of the front-side end portion and the back-side end portion of the side panel 10. The brackets 32 are respectively fastened with bolts 33 to the outer peripheral grooves 60a formed in the front-side end portion and the back-side end portion of the side panel 10.

[0043] As shown in FIG. 7(b), both end portions of the upper surface panel 31 are respectively held on the brackets 32, whereby the upper surface panel 31 is held near the upper end portion of the side panel 10. The upper surface panel 31 held near the upper end portion of the side panel 11 is also attached in the same manner.

[0044] The structures of the side panels 10 and 11, the back panel 12, the front panels 13a and 13b, and the upper surface panel 31 will be described. In the present embodiment, the structure of the back panel 12 illustrated in FIG. 8 will be described in detail, but the structures of the side panels 10 and 11, the front panels 13a and 13b, and the upper surface panel 31 are the same.

[0045] The inner surface (the surface facing the space S1 inside the booth) of the back panel 12 is a panel material having a panel structure in which a plurality of block portions 51 surrounded by two sets of grooves 50 extending substantially in parallel are arranged vertically and horizontally via the grooves 50, as shown in FIG. 8(a). The block portion 51 has a rectangular shape and is arranged over the entire inner surface of the back panel 12.

[0046] Specifically, as shown in FIG. 8(b), the rear panel 12 includes a lightweight core material 60 such as paper honeycomb, an MDF 61 (Medium Density Fiberboard) provided on one surface of the core material 60, an MDF 62 provided on the other surface of the core material 60, a surface layer material 63 provided to cover the MDF 61, and a covering material (lining) 64 provided to cover the MDF 62.

[0047] The core material 60 is a member disposed inside the rear panel 12. As described above, cutout portions 12c are formed at both ends of the upper surface of the rear panel 12, and the cutout portions 12c are formed at both ends of the upper end surface of the core material 60. Note that bolt holes 60c for fixing the connecting tool 14 with bolts 14a are formed in the cutout portions 12c, as shown in FIGS. 9(a) and 9(b).

[0048] A linear outer peripheral groove 60a is formed on the upper end surface of the core material 60 between the two cutout portions 12c. The outer peripheral groove 60a is formed at the central portion in the thickness direction of the core material 60, as shown in FIG. 9(b). Similarly, on the lower end surface of the core material 60, two cutout portions 12c disposed at both ends thereof and an outer peripheral groove 60a disposed between the two cutout portions 12c are formed. Also, on the left end surface and the right end surface of the core material 60, a linear outer peripheral groove 60a formed at the central portion in the thickness direction of the core material 60 is formed, as shown in FIG. 9(c).

[0049] As shown in FIG. 8(b), the surface layer material 63 is composed of three layers: a non-woven fabric 52 disposed on the MDF 61, a sound-absorbing material (urethane) 53 forming convex stripes, and a covering material 54 covering the surface of the sound-absorbing material 53. Therefore, the block portion 51 is composed of the non-woven fabric 52, the sound-absorbing material 53, and the covering material 54 in a region surrounded by two sets of grooves 50 extending substantially in parallel.

[0050] Thus, in the back panel 12, the block portion 51 is arranged on only one side of the back panel 12, and the surface on which the block portion 51 is arranged becomes the inner surface of the in-booth space S1 of the booth furniture 1. Note that, also for the side panels 10 and 11 and the front panels 13a and 13b, the block portion 51 is arranged on only one side. For the top panel 31, the block portion 51 is arranged on both sides.

[0051] Therefore, in the side panels 10 and 11, the back panel 12, and the front panels 13a and 13b, as shown in FIG. 1, a sound-absorbing material 53 forming a convex strip is provided at the portion facing the in-booth space S1 of the booth furniture 1, and the sound-absorbing material 53 forming a convex strip is not provided at the portion not facing the in-booth space S1. Note that, for the top panel 31, the sound-absorbing material 53 forming a convex strip is provided at the portion facing the in-booth space S1 of the booth furniture 1 and the portion not facing the in-booth space S1.

[0052] A procedure for providing the above-described surface layer material 63 having a three-layer structure so as to cover the MDF 61 provided on the core material 60 will be described with reference to FIG. 10.

[0053] The surface layer material 63 has a three-layer structure of a non-woven fabric 52, a sound-absorbing material 53, and a bonding material 54, and is formed to be longer than the length of the core material 60. Therefore, the surface layer material 63 is cut and used according to the length of the core material 60, such as the back panel 12.

[0054] First, the surface layer material 63 is brought close along the MDF 61 provided on the core material 60, and as shown in FIG. 10(a), it is confirmed that the groove 50A at the end of the block portion 51 is arranged along the end 60A of the core material 60.

[0055] After that, as shown in Fig. 10(b), the non-woven 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 bonding material 54 is not cut along the groove 50A at the end of the block portion 51. Therefore, the bonding material 54 covering the surface of the block portion 51 extends outside the end portion 60A of the core material 60. Note that, as will be described later, the bonding material 54 is cut to a length such that its end portion can be pushed into the outer peripheral groove 60a formed in the end face of the core material 60.

[0056] The surface layer material 63 obtained by cutting the non-woven fabric 52 and the sound-absorbing material 53 according to the length of the core material 60 is arranged on the surface of the MDF 61 provided on the core material 60 such that the groove 50A at the end of the block portion 51 coincides with the end portion 60A of the core material 60. In this state, as shown in Fig. 10(c), the end portion of the bonding material 54 is pushed into the outer peripheral groove 60a formed in the end face of the core material 60. Then, the surface layer material 63 is attached to the surface of the MDF 61 provided on the core material 60 without any gaps.

[0057] Note that the procedure for providing the bonding material 64 on the surface of the MDF 62 provided on the core material 60 so as to cover the surface of 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 is the same. That is, the bonding material 64 is cut according to the length of the core material 60, the bonding material 64 is arranged on the surface of the MDF 62 provided on the core material 60, and in this state, the end portion of the bonding material 64 is pushed into the outer peripheral groove 60a formed in the end face of the core material 60. Then, the bonding material 64 is attached to the surface of the MDF 62 provided on the core material 60 without any gaps.

[0058] As described above, on the side surface of the booth furniture 1, a cover 16 extending in the vertical direction is attached to the butting corner portion of the side panels 10 and 11 and the back panel 12, the butting corner portion of the front panel 13a and the side panel 10, and the butting corner portion of the front panel 13b and the side panel 11. The cover 16 is a 90-degree R type attached to the butting corner portion of two panel members connected at a right angle.

[0059] Hereinafter, a method of attaching the cover 16 to the booth furniture 1 will be described with reference to FIGS. 11 to 16. In the present embodiment, a method of attaching the cover 16 to the butting corner portion of the side panel 10 and the back panel 12 will be described, but the method of attaching the cover 16 to other butting corner portions is the same.

[0060] FIG. 11 shows a state in which the cover 16 is attached to the butting corner portion of the side panel 10 and the back panel 12 in the booth furniture 1. When the cover 16 is pulled in a direction away from the butting corner portion from that state, as shown in FIG. 12, the cover 16 is removed from the butting corner portion.

[0061] When the cover 16 is removed from the butting corner portion, a plurality of fixtures 80 for attaching the cover 16 to the edge portions of the side panel 10 and the back panel 12 become visible. FIG. 13 shows a state in which the plurality of fixtures 80 are removed from the edge portions of the side panel 10 and the back panel 12. The fixture 80 is configured to be detachable with respect to the edge portions of the core materials 60 of the side panel 10 and the back panel 12.

[0062] As shown in FIG. 14(a), the fixture 80 has a cylindrical central portion 80a, a first leg portion 81, a second leg portion 82, and a third leg portion 83. The first to third leg portions 81 to 83 are each formed in a plate shape and radially extend in three different directions from the central portion 80a. The first leg portion 81 is a portion that is inserted into an outer peripheral groove 60a formed in the edge portion of the core material 60. Therefore, the outer peripheral surface of the first leg portion 81 is formed in a shape that makes it difficult to come off from the outer peripheral groove 60a.

[0063] As shown in FIG. 14(b), the second leg portion 82 extends in a direction 90 degrees with respect to the first leg portion 81, and the third leg portion 83 extends in a direction 135 degrees with respect to the first leg portion 81. The second leg portion 82 and the third leg portion 83 are arranged on the opposite side to the first leg portion 81.

[0064] As described above, at the edge portions of the side panel 10 and the rear panel 12, the end portions of the stretch materials 54 and 64 are pushed into the outer peripheral groove 60a formed in the end face of the core material 60. However, when the first leg portion 81 is inserted into the outer peripheral groove 60a, it is attached to the end face of the core material 60. In that state, the first leg portion 81 is disposed between the stretch material 54 and the stretch material 64 within the outer peripheral groove 60a.

[0065] In addition, in the fixture 80, the second leg portion 82 and the third leg portion 83 are provided at positions 90 degrees with respect to the first leg portion 81 and further 135 degrees in the same direction therefrom. Therefore, when the fixture 80 is turned upside down, it becomes a symmetric shape. Thereby, as the fixture 80 attached to the edge portion of the side panel 10 and the fixture 80 attached to the edge portion of the rear panel 12, the parts can be made common.

[0066] As shown in FIG. 15, the cover 16 has a curved cover body 16a. On the inner surface of the cover body 16a, two attachment portions 16b extending parallel to the vertical direction are formed. The attachment portion 16b has two plate-like members extending in the vertical direction protruding from the inner surface of the cover body 16a. At the tip of the attachment portion 16b, an attachment groove 16c extending in the vertical direction is formed over the entire vertical direction of the attachment portion 16b. In this way, as an engaging portion to the leg portion of the fixture 80, two sets of attachment grooves 16c having a U-shaped cross section are arranged in parallel.

[0067] When attaching the cover 16 to the butting corner portion of the side panel 10 and the back panel 12, first, a plurality of fixtures 80 are attached to the edge portions of the core material 60 of the side panel 10 and the back panel 12 as shown in FIG. 12. In that case, for example, the plurality of fixtures 80 are attached to the edge portion of the core material 60 of the side panel 10 at height positions spaced apart in the vertical direction. Also, with respect to the edge portion of the core material 60 of the back panel 12, the plurality of fixtures 80 are attached at substantially the same height position as the height position at which the fixture 80 is attached to the edge portion of the core material 60 of the side panel 10. In FIG. 12, four fixtures 80 are attached to the edge portions of the side panel 10 and the back panel 12, respectively.

[0068] FIG. 16(a) shows a horizontal cross-section of the height position where the fixture 80 is attached to the edge portions of the core material 60 of the side panel 10 and the back panel 12. In the horizontal cross-section of FIG. 16(a), one fixture 80 is attached to the edge portion of the core material 60 of the side panel 10, and one fixture 80 is attached to the edge portion of the core material 60 of the back panel 12. At this time, the third leg portion 83 of the fixture 80 attached to the edge portion of the side panel 10 is oriented in a 135-degree direction with respect to the panel surface of the side panel 10. Similarly, the third leg portion 83 of the fixture 80 attached to the edge portion of the back panel 12 extends in a 135-degree direction with respect to the panel surface of the back panel 12.

[0069] In that state, as shown in FIG. 16(b), the cover 16 is attached from the direction in which the third leg portions 83 of the fixtures 80 attached to the edge portions of the side panel 10 and the back panel 12 extend. Specifically, the cover 16 is attached to the butting corner portion of the side panel 10 and the back panel 12 such that the third leg portion 83 of the fixture 80 is disposed within the attachment groove 16c formed on the inner surface of the cover 16. In the booth furniture 1 of the present embodiment, when the cover 16 is attached to the butting corner portion, the fixture 80 is covered by the cover 16 and becomes invisible from the outside.

[0070] Further, as shown in FIG. 15, locking projections 16t are formed near the upper end portion and the lower end portion on the inner surface of the cover body 16a. The locking projections 16t are formed so as to project from the inner surface of the cover body 16a. The two locking projections 16t are both of the same shape and are substantially rectangular plate-like members. When the cover 16 is attached to the butting corner portion so as to extend in the vertical direction, the lower surface of the locking projection 16t is disposed substantially horizontally.

[0071] Therefore, when attaching the cover 16 to the butting corner portion of the side panel 10 and the back panel 12, the lower surface of the locking projection 16t formed near the upper end portion of the cover body 16a is attached so as to contact the upper surface of the connector 14 that connects between the upper end portions of the butting corner portion of the side panel 10 and the back panel 12. Thereby, since the lower surface of the locking projection 16t of the cover 16 is locked to the upper surface of the connector 14, it is possible to prevent the cover 16 from moving downward.

[0072] Note that when the cover 16 is attached to the butting corner portion of the side panel 10 and the back panel 12, the locking projection 16t formed near the lower end portion of the cover body 16a is disposed at a position away from the connector 14, below the connector 14 that connects between the lower end portions of the butting corner portion of the side panel 10 and the back panel 12. In the present embodiment, two locking projections 16t are formed near the upper end portion and the lower end portion of the cover body 16a in order to enable the cover 16 to be attached to the butting corner portion of the side panel 10 and the back panel 12 even when the cover 16 is inverted in the vertical direction.

[0073] Note that, as described above, the bracket 32 for attaching the upper surface panel 31 is fixed with bolts 33 to the outer peripheral grooves 60a formed at the front side end portion and the back side end portion of the side panel 10 as shown in FIG. 17(a). However, as shown in FIG. 17(b), the bracket 32 is attached by fastening the bolts 33 to the bolt holes 60a1 formed at the bottom surface of the outer peripheral groove 60a.

[0074] As described above, the booth furniture 1 of the present embodiment is a booth furniture in which the side panels 10, 11 and the back panel 12 are connected in a plurality of U - shaped forms to form an internal space with at least one side being open. The edge portions of the side panels 10, 11 and the back panel 12 are detachable, and have a fixture 80 for attaching the cover 16 from a direction of 90 degrees or 135 degrees with respect to the panel surface. The fixture 80 has first to third legs 81 to 83 radially extending in three directions from the central portion 80a. The second leg 82 and the third leg 83 extend in the directions of 90 degrees and 135 degrees with respect to the first leg 81, respectively.

[0075] In this way, optional parts such as the cover 16 can be easily attached to the edge portions of the side panels 10, 11 and the back panel 12 included in the booth furniture 1 via the fixture 80.

[0076] In the booth furniture 1 of the present embodiment, it has vertical outer peripheral grooves 60a formed at the left and right edges of the side panels 10, 11 and the back panel 12. The first leg 81 of the fixture 80 is in a plate shape to be inserted into the vertical outer peripheral grooves 60a.

[0077] In this way, when attaching the fixture 80 to the edge portions of the side panels 10, 11 and the back panel 12, by inserting the plate - shaped first leg 81, the fixture 80 can be firmly fixed to the edge portions of the side panels 10, 11 and the back panel 12. Also, the attachment position of the fixture 80 can be guided by the outer peripheral grooves 60a formed at the left and right edges of the side panels 10, 11 and the back panel 12.

[0078] In the booth furniture 1 of the present embodiment, the fixture 80 has the second leg 82 at a position 90 degrees with respect to the first leg 81, and further has the third leg 83 at a position 135 degrees in the same direction therefrom, and becomes a symmetric shape when turned upside down.

[0079] In this way, since the fixture 80 is configured in a symmetric shape when turned upside down, the same fixture 80 can be used on the left and right.

[0080] In the booth furniture 1 of the present embodiment, as an engagement portion of the cover 16, which is an optional component, with the leg portion of the fixture 80, two sets of engagement portions having a U-shaped cross section are arranged in parallel.

[0081] In this way, the fixture 80 and the cover 16 can be attached only by inserting the engagement portion of the cover 16 into the leg portion of the fixture 80 from one direction.

[0082] In the booth furniture 1 of the present embodiment, the cover 16, which is an optional component, is attached to, for example, the butting corner portion of the side panel 10 and the back panel 12 that are connected at a right angle.

[0083] In this way, the cover can be easily attached to the butting corner portion of the two panel members that are connected at a right angle.

[0084] In the booth furniture 1 of the present embodiment, when the cover 16 is attached to, for example, the butting corner portion of the side panel 10 and the back panel 12 that are connected at a right angle, the fixture 80 is covered by the cover 16 and becomes invisible from the outside.

[0085] In this way, since the fixture 80 is covered by the cover 16 and becomes invisible from the outside, the appearance of the butting corner portion is improved.

[0086] In the booth furniture 1 of the present embodiment, for example, at the butting corner portion of the side panel 10 and the back panel 12, the upper end portions of the adjacent side panel 10 and back panel 12 are connected by a connector 14, and on the inner surface of the cover 16, a locking projection 16t that is locked to the upper surface of the connector 14 in a state of being attached to the butting corner portion is formed.

[0087] In this way, in a state where the cover 16 is attached to the butting corner portion, it is possible to prevent the cover 16 from moving downward.

[0088] (Second Embodiment) The main difference between the booth furniture 101 of this embodiment and the booth furniture 1 of the first embodiment is that in the first embodiment, the booth furniture 1 is used alone, while in this embodiment, two booth furniture 101 are used as a booth unit. In the configuration of the booth furniture 101 of this embodiment, detailed descriptions of the parts that are the same as the configuration of the booth furniture 1 of the first embodiment are omitted.

[0089] Two booth furniture 101 are arranged vertically in series to form a booth unit. The booth furniture 101a and the booth furniture 101b have the same configuration, and in the booth furniture 101a and the booth furniture 101b, one rear panel 112 is shared.

[0090] The booth furniture 101 shown in FIGS. 18 and 19 includes a pair of side panels 110 and 111 arranged opposite to each other, and a rear panel 112 connected between one end portion (rear side end portion) 110a and 111a of these side panels 110 and 111. The whole forms a U-shape in plan view to be self-supporting, and forms a booth inner space S101 that becomes a living space inside. Inside the booth furniture 101, a table 102 is arranged. The top plate 102a of the table 102 is rectangular and is arranged along the inner surfaces of the side panels 110 and 111 and the inner surface of the rear panel 112.

[0091] The lateral widths of the side panels 110 and 111 and the rear panel 112 are smaller than the lateral widths of the side panels 10 and 11 and the rear panel 12 of the first embodiment. Note that the structures of the side panels 110 and 111 and the rear panel 112 are substantially the same as the structures of the side panels 10 and 11 and the rear panel 12 of the first embodiment.

[0092] In the booth furniture 101, as shown in FIGS. 18 and 19, above the booth interior space S101, an upper panel 131 is provided that extends 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 disposed upward as it moves away from the rear panel 112. The upper end of the upper panel 131 is disposed at substantially the same height as the upper end of the rear panel 112. Further, 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.

[0093] In the booth furniture 101, as shown in FIG. 18, the upper panel 131 is disposed near the upper end of the rear panel 112. 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 in the same manner as in the first embodiment. By holding both ends of the upper panel 131 on the brackets respectively, the upper panel 131 is held near the upper end of the rear panel 112.

[0094] The upper panel 131 is attached to the upper part of the rear panel 112 that hits above the top plate 102a of the table 102 disposed along the inner surface of the rear panel 112 of the booth interior space S110. By disposing the upper panel 131 at the upper position of the top plate 102a, the voice of the seated person in the chair in front of the table 102 that is reflected upward by the top plate 102a is effectively absorbed. By the above, a sound absorption effect is obtained that effectively reduces the leakage of the voice of a person talking in a Web conference or the like while sitting in the booth upward.

[0095] On the side surface of the booth unit of the present embodiment, at the butting corner portion of the side panels 10, 11 and the rear panel 12, a cover (end cover) 116 extending in the vertical direction is attached. The cover 116 is of a 3Way flat plate type attached to the butting corner portion of three panel materials connected in a substantially T shape. When attaching the cover 116 to the butting corner portion, the same fixture 80 as in the first embodiment is used.

[0096] Next, a method for attaching the cover 116 to the butting corner portion of the side panels 10 and 11 and the rear panel 12 will be described with reference to FIG. 19.

[0097] As shown in FIG. 19, the cover 116 has a flat cover body 116a. On the inner surface of the cover body 116a, two attachment portions 116b extending parallel to the vertical direction are formed. The attachment portions 116b are formed so as to protrude from the inner surface of the cover body 116a. At the tip of the attachment portion 116b, an attachment groove 116c extending in the vertical direction is formed over the entire vertical range of the attachment portion 116b.

[0098] When attaching the cover 116 to the butting corner portion of the side panels 10 and 11 and the rear panel 12, first, a plurality of fixtures 80 are attached to the edge portions of the core materials 60 of the side panels 110 and 111. In that case, for example, a plurality of fixtures 80 are attached to the edge portion of the core material 60 of the side panel 110 at a height position spaced apart in the vertical direction. Also, with respect to the edge portion of the core material 60 of the side panel 111, a plurality of fixtures 80 are attached at a height position substantially the same as the height position where the fixtures 80 are attached to the edge portion of the core material 60 of the side panel 10.

[0099] FIG. 20(a) shows a horizontal cross-section of the height position where the fixture 80 is attached to the edge portions of the core materials 60 of the side panels 110 and 111. In the horizontal cross-section of FIG. 20(a), one fixture 80 is attached to the edge portion of the core material 60 of the side panel 110, and one fixture 80 is attached to the edge portion of the core material 60 of the side panel 111. At this time, the second leg portion 82 of the fixture 80 attached to the edge portion of the side panel 110 is oriented in a direction 90 degrees with respect to the panel surface of the side panel 110. Similarly, the second leg portion 82 of the fixture 80 attached to the edge portion of the side panel 111 extends in a direction 90 degrees with respect to the panel surface of the side panel 111.

[0100] In that state, as shown in FIG. 20(b), the cover 116 is attached from the direction in which the second leg portion 82 of the fixture 80 attached to the edge portions of the side panels 10 and 11 extends. Specifically, the cover 116 is attached to the butting corner portion of the side panels 110 and 111 and the rear panel 112 such that the second leg portion 82 of the fixture 80 is disposed in the attachment groove 116c formed on the inner surface of the cover 116. In the booth furniture 101 of the present embodiment, when the cover 116 is attached to the butting corner portion, the fixture 80 is covered by the cover 116 and becomes invisible from the outside.

[0101] Also, on the inner surface of the cover main body 116a, locking protrusions (not shown) are formed in the vicinity of the upper end portion and the lower end portion thereof, similar to the cover 16 of the first embodiment. Therefore, when the cover 116 is attached to the butting corner portion of the side panels 110 and 111 and the rear panel 12, the lower surface of the locking protrusion of the cover 116 is locked to the upper surface of the connecting member, so that the cover 116 can be prevented from moving downward.

[0102] In the booth furniture 101, an upper surface panel 131 is attached in the vicinity of the upper end portion of the rear panel 112, and a lighting fixture 135 is attached below it. Also, a table 102 is disposed inside the booth furniture 101. The top plate 102a of the table 102 is rectangular and is disposed along the inner surfaces of the side panels 110 and 111 and the inner surface of the rear panel 112.

[0103] Therefore, brackets 132 for attaching the upper surface panel 131 are provided in the vicinity of the upper end portions of the left and right end portions of the rear panel 112. This is the same as in the first embodiment, where brackets 32 for attaching the upper surface panel 31 are provided in the vicinity of the upper end portions of the front and rear end portions of the side panels 10 and 11.

[0104] In addition, brackets 136 for attaching lighting fixtures 135 are provided at the left and right ends of the rear panel 112. In the present embodiment, the brackets 136 are integrally provided at both ends of the lighting fixture 135.

[0105] In addition, near the central portions in the height direction of the left and right ends of the rear panel 112, top plate supports 103 for supporting the top plate 102a of the table 102 are provided. Note that both ends of the rear side end portion of the top plate 102a of the table 102 are supported by the top plate supports 103, and both ends of the front side end portion of the top plate 102a are supported by the legs 102c. The two legs 102c are respectively fixed to both front side end portions of the lower surface of the top plate 102a.

[0106] As shown in FIG. 21, brackets 132a, 136a, and top plate supports 103a for the booth furniture 101a, and brackets 132b, 136b, and top plate supports 103b for the booth furniture 101b are attached to the left end of the rear panel 112. The same applies to the right end of the rear panel 112.

[0107] In this way, when attaching the two brackets 132a and 132b for attaching the upper panel 131 back-to-back to the rear panel 112, the bracket 132a has an attachment portion 132a1, and the bracket 132b has attachment portions 132b1 and 132b2. In that case, with respect to the left end of the rear panel 112, in the vertical direction, the attachment portion 132a1 of the bracket 132a is attached so as to be disposed between the attachment portion 132b1 and the attachment portion 132b2 of the bracket 132b.

[0108] In that state, with respect to the left end of the rear panel 112, the attachment portion 132a1 of the bracket 132a is fixed to the outer peripheral groove 60a formed in the end face of the core material 60 with the bolt 133, and the attachment portions 132b1 and 132b2 of the bracket 132b are respectively fixed to the outer peripheral groove 60a formed in the end face of the core material 60 with the bolt 133. Thereby, even when the brackets 132a and 132b are attached using the entire thickness of the rear panel 112, they do not overlap.

[0109] Similarly, when attaching two brackets 136a and 136b for attaching the lighting fixture 135 to the back panel 112 back-to-back, the bracket 136a has attachment portions 136a1 and 136a2, and the bracket 136b has attachment portions 136b1 and 136b2. In that case, with respect to the left end of the back panel 112, in the vertical direction, the attachment portion 136a1 of the bracket 136a is attached so as to be disposed between the attachment portion 136b1 and the attachment portion 136b2 of the bracket 136b. Further, the attachment portion 136b2 of the bracket 136b is attached so as to be disposed between the attachment portion 136a1 and the attachment portion 136a2 of the bracket 136a.

[0110] With respect to the left end of the back panel 112, the attachment portion 136a1 and the attachment portion 136a2 of the bracket 136a are fastened to the outer peripheral groove 60a formed in the end face of the core material 60 by bolts 133 respectively, and the attachment portion 136b1 and the attachment portion 132b2 of the bracket 136b are fastened to the outer peripheral groove 60a formed in the end face of the core material 60 by bolts 133 respectively. Thereby, even when the brackets 136a and 136b are attached using the entire thickness of the back panel 112, they do not overlap.

[0111] Similarly, when attaching two brackets 103a and 103b for attaching the top plate receiver 103 to the back panel 112 back-to-back, the bracket 103a has attachment portions 103a1 and 103a2, and the bracket 103b has attachment portions 103b1 and 103b2. In that case, with respect to the left end of the back panel 112, in the vertical direction, the attachment portion 103a2 of the bracket 103a is attached so as to be disposed between the attachment portion 103b1 and the attachment portion 103b2 of the bracket 103b. Further, the attachment portion 103b1 of the bracket 103b is attached so as to be disposed between the attachment portion 103a1 and the attachment portion 103a2 of the bracket 103a.

[0112] With respect to the left end of the back panel 112, the attachment portions 103a1 and 103a2 of the bracket 103a are fixed to the outer peripheral groove 60a formed on the end face of the core material 60 with bolts 133, respectively, and the attachment portions 103b1 and 103b2 of the bracket 103b are fixed to the outer peripheral groove 60a formed on the end face of the core material 60 with bolts 133, respectively. In this way, even if the brackets 103a and 103b are attached using the entire thickness of the back panel 112, they do not overlap.

[0113] As described above, after the bracket 132 for attaching the upper panel 131, the bracket 136 for attaching the lighting fixture 135, and the bracket 103 for attaching the top plate receiver 103 are attached to the left end of the back panel 112, the back side end of the side panel 110 is connected to the left end of the back panel 112.

[0114] In that state, when looking at the bracket 132 for attaching the upper panel 131 from inside the booth furniture 101, as shown in Fig. 22(a), the vicinity of the attachment portion of the bracket 132 is hidden at the connection portion between the back panel 112 and the side panel 110 and is not conspicuous, and is neatly accommodated.

[0115] Similarly, when looking at the bracket 103 for attaching the top plate receiver 103 from inside the booth furniture 101, as shown in Fig. 22(b), the vicinity of the attachment portion of the bracket 103 is hidden at the connection portion between the back panel 112 and the side panel 110 and is not conspicuous, and is neatly accommodated.

[0116] In the booth furniture 101 of this embodiment, the cover 116, which is an optional part, For example, it is attached to the butting corner portion of the side panels 110 and 111 and the back panel 112 that are connected in a substantially T shape.

[0117] By doing so, the cover 116 can be easily attached to the butting corner portion of the side panels 110 and 111 and the back panel 112 that are connected in a substantially T shape.

[0118] As described above, in the booth unit having the side panels 110 and 111 and the back panel 112 which are the panel furniture of the present embodiment, the same effects as those of the first embodiment can be obtained.

[0119] (Third Embodiment) The main difference between the booth furniture 201 of the present embodiment and the booth furniture 1 of the first embodiment is that in the booth furniture 1 of the first embodiment, two upper panels 31 are provided, while in the booth furniture 201 of the present embodiment, no upper panel is provided. In the configuration of the booth furniture 201 of the present embodiment, detailed description of the parts that are the same as the configuration of the booth furniture 1 of the first embodiment will be omitted.

[0120] The booth furniture 201 shown in FIG. 23 includes a pair of side panels 10 and 11 arranged opposite to each other, and a back panel 12 connected between one ends (rear side ends) 10a and 11a of these side panels 10 and 11. The whole is made self - standing by forming a U - shape in plan view, and forms a booth inner space S1 which becomes a living space inside. Inside the booth furniture 201, a table 202 having a top plate 202a is arranged. The table 202 is arranged at a substantially central part of the booth inner space S1.

[0121] In the booth furniture 201 of the present embodiment, as shown in FIG. 23, two sets of sound - absorbing panels 80A are arranged above the booth inner space S1. The two sets of sound - absorbing panels 80A both have substantially the same configuration. One set of sound - absorbing panels 80A includes three sound - absorbing panels 80a to 80c respectively. The sound - absorbing panels 80a to 80c are respectively suspended from the ceiling via suspension members 82. The sound - absorbing panels 80a to 80c all have the same configuration and are flat - plate members having a substantially circular shape in plan view. In the following description, each of the sound - absorbing panels 80a to 80c may be simply referred to as a sound - absorbing panel 80.

[0122] The sound-absorbing panels 80a to 80c are respectively suspended from the ceiling via suspension members 81 so as to be disposed above the space S1 inside the booth. The sound-absorbing panels 80a to 80c are arranged with different horizontal positions in plan view. That is, the three sound-absorbing panels 80a to 80c are arranged so as not to overlap in plan view. Further, the three sound-absorbing panels 80a to 80c are arranged with different height positions. That is, the sound-absorbing panel 80a is disposed at the lowest height position, and the sound-absorbing panels 80b and 80c are disposed at higher height positions in this order.

[0123] The configuration of the sound-absorbing panel 80 will be described based on FIG. 24.

[0124] The sound-absorbing panel 80 is substantially circular in shape and is formed in a flat plate shape. The sound-absorbing panel 80 is configured in the same manner as the above-described rear panel 12 and the like. That is, the lower surface (the surface facing the space S1 inside the booth) of the sound-absorbing panel 80 is a panel material having a panel structure in which a plurality of block portions 51 surrounded by two sets of grooves 50 extending substantially in parallel are arranged vertically and horizontally via the grooves 50. The block portion 51 has a rectangular shape and is disposed over the entire lower surface of the sound-absorbing panel 80.

[0125] Specifically, the sound-absorbing panel 80 has, in the same manner as the above-described rear panel 12 and the like, a lightweight core material 60 such as paper honeycomb, an MDF 61 (Medium Density Fiberboard) provided on one surface of the core material 60, an MDF 62 provided on the other surface of the core material 60, a surface layer material 63 provided so as to cover the MDF 61, and a covering material (lining) 64 provided so as to cover the MDF 62.

[0126] The surface layer material 63 is composed of three layers: a nonwoven fabric 52 disposed on the MDF 61, a sound-absorbing material (urethane) 53 forming a ridge, and a covering material 54 covering the surface of the sound-absorbing material 53. Therefore, the block portion 51 is composed of the nonwoven fabric 52, the sound-absorbing material 53, and the covering material 54 in a region surrounded by two sets of grooves 50 extending substantially in parallel.

[0127] As described above, in the booth furniture 201 of the present embodiment, a plurality of sound absorption panels 80 are arranged above the top plate 202a of the table 202 installed in the booth interior space S1. Therefore, in the booth furniture 201, the sound absorption panel 80 effectively absorbs the sound that is reflected upward by the top plate 202a when a seated person seated around the table 202 makes a sound.

[0128] As described above, in the booth furniture 201 of the present embodiment, the same effects as those of the booth furniture 1 of the first embodiment can be obtained.

[0129] (Fourth Embodiment) The main difference between the booth furniture 301 of the present embodiment and the booth furniture 1 of the first embodiment is that in the booth furniture 1 of the first embodiment, two upper surface panels 31 and front panels 13a, 13b are provided, while in the booth furniture 301 of the present embodiment, the upper surface panel and the front panel are not provided. In the configuration of the booth furniture 301 of the present embodiment, detailed descriptions of the parts that are the same as those in the configuration of the booth furniture 1 of the first embodiment are omitted.

[0130] The booth furniture 301 shown in FIG. 25 includes a pair of side panels 10 and 11 arranged opposite to each other, and a rear panel 12 connected between one ends (rear side ends) 10a and 11a of these side panels 10 and 11. The whole is made self - supporting by forming a U - shape in plan view, and forms a booth interior space S1 that serves as a living space inside. Inside the booth furniture 301, a table 302 having a top plate 302a is arranged. The table 302 is arranged at a substantially central portion of the booth interior space S1.

[0131] Between the vicinity of the central portion of the upper end of the side panel 10 and the vicinity of the central portion of the upper end of the side panel 11, two mounting members 81a and 81b are spanned substantially in parallel. 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 with respect to the mounting member 81a.

[0132] In the booth furniture 301 of the present embodiment, four sound absorption panels 380a and four sound absorption panels 380b are arranged above the space S1 inside the booth. The four sound absorption panels 380a and the four sound absorption panels 380b are all arranged at substantially the same height. As shown in FIG. 26, the sound absorption panels 380a and 380b each have a hole 380c formed at the front end and a hole 380c formed at the rear end. Therefore, the sound absorption panel 380a and the sound absorption panel 380b are supported by inserting the attachment member 81a into the hole 380c at the front end and inserting the attachment member 81b into the hole 380c at the rear end.

[0133] The sound absorption panels 380a and 380b are both long flat plate-shaped members having a predetermined length. The sound absorption panels 380a and the sound absorption panels 380b are alternately arranged substantially in parallel in a direction approaching from the side panel 10 to the side panel 11. When the booth furniture 301 is viewed from the front, the sound absorption panel 380a is inclined so that its right end is arranged at a higher position than its left end, and the sound absorption panel 380b is inclined so that its left end is arranged at a higher position than its right end.

[0134] Thus, in the booth furniture 301 of the present embodiment, the sound absorption panels 380a and 380b are supported with a gap in the attachment members 81a and 81b that span the upper ends of the opposing side panels 10 and 11. As a result, the sound absorption panels 380a and 380b are arranged above the top plate 302a of the table 302 installed in the booth space S1 with a gap. Therefore, the voices of the seated persons sitting around the table 302 in the booth furniture 301 are effectively absorbed by the sound absorption panels 380a and 380b, which reflect upward from the top plate 302a.

[0135] As described above, in the booth furniture 301 of the present embodiment, the same effects as those of the booth furniture 1 of the first embodiment can be obtained.

[0136] As described above, the embodiments of the present invention have been described, but the configuration of each part is not limited to only the above-described embodiments.

[0137] In the above first embodiment, the first leg portion 81 of the fixture 80 is in a plate shape that is inserted into the outer peripheral groove 60a formed at the left and right edges of the side panels 10 and 11 and the back panel 12, but it is not limited thereto. When the first leg portion 81 of the fixture 80 is inserted into the outer peripheral groove 60a, the first leg portion 81 of the fixture 80 does not have to be formed in a plate shape. Also, the outer peripheral groove 60a may not be formed at the left and right edges of the side panels 10 and 11 and the back panel 12, and the fixture 80 may be attached to the left and right edges of the side panels 10 and 11 and the back panel 12 by a method such as screwing. The same applies to the second to fourth embodiments.

[0138] In the above first embodiment, an example of the shape of the fixture 80 is shown, but the shape of the fixture 80 is arbitrary. For example, the number, arrangement, and length of the leg portions of the fixture 80 are arbitrary. The same applies to the second to fourth embodiments.

[0139] In the above first embodiment, the cover 16 has two sets of mounting grooves (engaging portions) with a U-shaped cross-section arranged in parallel as engaging portions for the leg portions of the fixture 80, but it is not limited thereto. The configuration of the engaging portion for the leg portion of the fixture 80 formed on the inner surface of the cover 16 is arbitrary. The same applies to the second to fourth embodiments.

[0140] In the above first embodiment, the case where the cover 16 as an optional part is attached to the left and right edges of the panel material 12P of the back panel 12 via the fixture 80 has been described, but the optional part attached to the edge of the panel material is arbitrary. That is, an optional part other than the cover 16 may be used. The same applies to the second to fourth embodiments.

[0141] In the above-described first embodiment, the first leg portion 81 of the fixture 80 is inserted into the outer peripheral groove 60a formed at the edge portion of the panel material, so that when the fixture 80 is attached to the edge portion of the panel material, the first leg portion 81 is disposed between the tension member 54 and the tension member 64 within the outer peripheral groove 60a over its entire length. However, the present invention is not limited thereto. For example, as shown in FIG. 28, a groove portion 160a1 having a width smaller than that of the outer peripheral groove 60a is formed on the bottom surface of the outer peripheral groove 60a, and the fixture 180 may be attached to the edge portion of the panel material by inserting the tip end portion of the first leg portion 181 of the fixture 180 into the groove portion 160a1. Note that the first leg portion 181 of the fixture 180 is formed longer than the length of the first leg portion 81 of the fixture 80 in the first embodiment. In that case, the end portions of the tension member 54 and the tension member 64 may be disposed within the outer peripheral groove 60a and not within the groove portion 160a1.

[0142] In the booth furniture 1 according to the first embodiment, a wire holder 360 for fixing wiring T or the like may be attached to the edge portions of the front panels 13a and 13b.

The wire housing portion 360a is formed in a substantially cylindrical shape, and wiring can be housed therein. The protruding portion 360b is a portion that is inserted into the outer peripheral groove 60a formed at the edge portion of the front panel 13a when the wire holder 360 is attached to the edge portion of the front panel 13a.

[0144] To explain an example of using the wire holder 360, as shown in FIGS. 29(a) and 29(b), the protruding portion 360b of the wire holder 360 is inserted into the outer peripheral groove 60a formed at the edge portion of the front panel 13a for attachment. Then, as shown in FIG. 29(c), by disposing the wiring T within the wire housing portion 360a of the wire holder 360 attached to the edge portion of the panel material, the wiring T or the like can be fixed to the edge portion of the front panel 13a.

[0145] In the above description, after the wire collecting tool 360 is attached to the edge of the front panel 13a, the wiring T is accommodated in the wiring accommodation portion 360a. However, after the wiring T is accommodated in the wiring accommodation portion 360a, the wire collecting tool 360 may be attached to the edge of the front panel 13a.
